The present invention relates to a medicine dispensing apparatus for inspecting a medicine such as a tablet, a capsule and a suppository before the medicine is packaged.
Heretofore, as an apparatus which can perform inspection related to medicine dispensing, there are provided an apparatus which photographs a medicine before the medicine is packaged to perform the inspection and an apparatus which photographs the medicine after the medicine has been packaged to perform the inspection.
For example, as the former apparatus, there is provided an apparatus which supplies only tablets required to be inspected on a turn table to photograph the tablets with a camera and then carries the tablets from a discharging hopper through a carrying conveyer to package the tablets for every one package with a packaging device as disclosed in patent document 1. Further, for example, as the latter apparatus, there is provided an apparatus which photographs tablets which have been packaged with a photographing device with illuminating the tablets with an illumination device to count the number of the tablets from an image of shadows of the tablets as disclosed in patent document 2.
In the tablet packaging apparatus of the patent document 1, although the tablets required to be inspected can be photographed with the camera, a photographed surface of each tablet is limited to a surface (front surface) directed toward the side of the camera and it is impossible to photograph a rear surface of each tablet. Namely, the tablet packaging apparatus of the patent document 1 is configured to recognize an external view of a medicine based on an image photographed with the camera to identify medicine information. Thus, in the tablet packaging device of the patent document 1, any surface constituting the medicine may be photographed by the camera as long as it is possible to obtain an image from which an external shape of the tablet can be recognized. On the other hand, since the identification for the medicine is performed based on the external shape of the medicine, it requires a complex process such as image processing and further there is a concern that a sufficient inspection accuracy cannot be obtained in a case where other medicines having a similar external view is mistakenly handled or the like.
Further, in the case where the inspection is performed after the medicine has been packaged in packaging paper as disclosed in the patent document 2, the tablet is photographed in a state that the packaging paper intervenes. Thus, in the case of taking the configuration as disclosed in the patent document 2, there is a problem that it is difficult to read an engraved mark engraved on the surface of the medicine or the like and it is impossible to perform other inspection than the counting of the number of the medicines. Specifically, there is a problem that marks for a patient name, a medicine name or the like attached to the packaging paper are overlapped with the medicine and thus it is difficult to read information such as the engraved mark attached to the medicine.
Thus, the present invention is intended to provide a medicine packaging apparatus whose reading accuracy for identification information such as an engraved mark attached to a medicine is high and which can provide superior inspection performance.
A medicine packaging apparatus of the present invention provided for solving the above-described problem is characterized by comprising a medicine preparing and dispensing portion for preparing medicines so that the medicines can be dispensed, a packaging portion for packaging the medicines dispensed from the medicine preparing and dispensing portion, a pre-packaging photographing portion including a medicine photographing device for photographing the medicines dispensed from the medicine preparing and dispensing portion in a phase before the medicines are packaged by the packaging portion, an individually supplying portion which can individually supply the plurality of medicines received from the side of the medicine preparing and dispensing portion to the side of the pre-packaging photographing portion, and a control part, wherein the control part includes a reading control part for reading identification information attached to the medicine based on an image photographed by the pre-packaging photographing portion and an inspection processing part for performing an inspection process based on the identification information read by the reading control part and prescription information.

According to such a configuration, it is possible to prepare the medicines supplied from the side of the medicine preparing and dispensing portion into the plurality of provided receiving portions in sequence and move the rotating body into the working area of each of the receiving portions to perform the delivery action, thereby supplying the medicines to the side of the pre-packaging photographing portion one after another. This makes it possible to efficiently perform the action for individually and one by one supplying the medicines to the side of the pre-packaging photographing portion in the individually supplying portion.
Here, in order to precisely perform an operation for individually and one by one holding the plurality of medicines prepared in the receiving portion by the delivering portion, it is preferable that the medicines are dispersed in the receiving portion.
The medicine packaging apparatus of the present invention provided based on such knowledge is configured so that the medicines supplied from the side of the medicine preparing and dispensing portion are supplied to a position which is in the receiving portion and on the side of the axial center position of the rotating body.
According to such a configuration, the medicines supplied to positions eccentrically located at positions on the side of the axial center position of the rotating body in the receiving portion are individually dispersed in the receiving portion along with rotation of the rotating body and thus the medicines become in a separated state. Thus, at the time when the receiving portion reaches the working area of the delivering portion due to the rotation of the rotating body, the medicines become in a sufficiently separated state in the receiving portion and thus it becomes easier to one by one hold the medicines with the delivering portion.
Here, it is easier to hold a medicine existing at a position away from a wall surface constituting the receiving portion compared with a medicine existing in the vicinity of the wall surface constituting the receiving portion at the time of performing the action for holding the medicine with the delivering portion.
The medicine packaging apparatus of the present invention provided based on such knowledge is characterized that the control part has a rotating body control part for controlling the rotation of the rotating body and when the rotating body control part rotates the rotating body to move the receiving portion to a predetermined position in the working area, the rotating body control part rotates the rotating body so that the receiving portion rotates to a position over the predetermined position and then rotates the rotating body so that the receiving portion returns to the predetermined position.
According to such a configuration, the medicines are likely to be in a state that the medicines are separated from the wall surface constituting the receiving portion at the time when the receiving portion reaches the working area of the delivering portion along with the rotation of the rotating body. This makes it much easier to perform the action for one by one holding the medicines with the delivering portion.
Here, when the rotating body is rotated so that the receiving portion reaches the working area of the delivering portion, the medicines roll in the receiving portion. Thus, in order to allow the delivering portion to precisely hold the medicines in the receiving portion reaching the working area, it is preferable to take a configuration in which the rolling of the medicines stops and the medicines become in a stable state as soon as possible.
The medicine packaging apparatus of the present invention provided based on such knowledge is configured so that the receiving portion has a receiving portion side wall provided to stand, a receiving area for receiving the medicines is provided inside the receiving portion side wall and a shape of the receiving area is non-circular.

In this embodiment, the individually supplying portion 60 is configured to receive the medicines dispensed from the manually distributing portion 24 in the medicine preparing and dispensing portion 20 and individually supply the medicines to the side of the pre-packaging photographing portion 100. As shown in
As shown in
The plurality of receiving portions 72 (in this embodiment, the number of the receiving portions 72 is three) are provided on the rotating body 68. The receiving portions 72 are configured so that three openings provided in the front plate 68a are defined as the receiving ports 72a and the receiving portions 72 respectively include receiving areas 72b which can receive the medicines from the side of the medicine preparing and dispensing portion 20. The receiving areas 72b are areas respectively surrounded by the rear plate 68b and the receiving tubes 72c provided in the space 68f so as to correspond to each receiving port 72a. The medicines for one package are contained in the receiving area 72b (the receiving tube 72c). The receiving tube 72c is a tubular member whose inner circumferential surface 72d (a receiving portion side wall) is non-circular. In this embodiment, the receiving tube 72c is a tubular member in which a curved portion is formed on the inner circumferential surface 72d. More specifically, a cross-sectional shape of the receiving area 72b is a substantially polygonal shape (in this embodiment, the cross-sectional shape is a hexagonal shape).
Further, the receiving tube 72c is configured to be slidably moved between the receiving port 72a and a discharging port 74 described later when the collectively discharging mechanism 73 is actuated. The collectively discharging mechanism 73 is used for moving the receiving tube 72c from the side of the receiving port 72a to the side of the discharging port 74 to collectively discharge the medicines existing in the receiving tube 72c toward the discharging port 74. Although the collectively discharging mechanism 73 may be any mechanism as long as it has this described function, the collectively discharging mechanism 73 is configured as follows in this embodiment. Specifically, as shown in
The receiving port side unit 73a is connected to the receiving tube 72c and can be combined with the discharging port side unit 73b to slidably move the receiving tube 72c between the receiving port 72a and the discharging port 74. More particularly, the receiving tube 72c has an arm 72e protruding from an outer circumferential portion toward an outer side of a radial direction of the receiving tube 72c. The receiving tube 72c has a pinion portion 72f provided at a tip end portion of the arm 72e. Further, the receiving tube 72c is configured to be pivotally moved with respect to the rotating body 68 around a support axis 72g provided to stand on a substantially center portion of the pinion portion 72f. The receiving port side unit 73a includes a slide piece 73c, a slide guide 73d and a spring 73e. The slide piece 73c has a rack portion 73f at a tip end portion thereof. The slide piece 73c is configured to be slidably moved along the slide guide 73d fixed to the rear plate 68b of the rotating body 68. Further, the rack portion 73f is meshed with the pinion portion 72f. The spring 73e for applying biasing force to the slide piece 73c toward a tip end side (the side of the pinion portion 72f) thereof is arranged between a base end portion (an end portion opposite to the pinion portion 72f) of the slide piece 73c and the slide guide 73d.
The receiving port side unit 73a can pivotally move the pinion portion 72f in a positive direction by applying external force against the above-described biasing force to push the slide piece 73c along the slide guide 73 in a direction toward the base end side. Further, by pivotally moving the pinion portion 72f in the positive direction, it is possible to move (pivotally move) the receiving tube 72c around the support axis 72g. This makes it possible to move the receiving tube 72c existing on the side of the receiving port 72a in a normal state to the side of the discharging port 74 to collectively discharge the medicines in the receiving tube 72c to the discharging port 74. On the other hand, when the external force in the direction for pushing the slide piece 73c toward the base end side is released, the slide piece 73c is pushed back by an action of the spring 73e. Along with this movement, the receiving tube 72c is returned from the side of the discharging port 74 to the side of the receiving port 72a and returns to a state that the receiving tube 72c can receive the medicines through the receiving port 72a.
Whereas the above-described receiving port side units 73a are provided for each receiving tube 72c, the discharging port side unit 73b is only provided at a position adjacent to the discharging port 74. The discharging port side unit 73b is used for applying the external force with respect to the slide piece 73c of the receiving port side unit 73a. The discharging port side unit 73b has a motor 73g and a cam 73h and can pivotally move the cam 73h with driving force of the motor 73 transmitted through gears 73i, 73j connected to rotation axes of the motor 73g and the cam 73h. The cam 73h is arranged at a position at which the cam 73h can contact with the slide piece 73c of the receiving port side unit 73a corresponding to the receiving tube 72c reaching a position adjacent to the discharging port 74. The receiving port side unit 73a can actuate the motor 73g and pivotally move the cam 73h to change pressing force acting to the slide piece 73c. Thus, the collectively discharging mechanism 73 can move the receiving tube 72c between the side of the receiving port 72a and the side of the discharging port 74 and collectively discharge the medicines in the receiving tube 72c to the discharging port 74 due to an interaction of the receiving port side unit 73a and the discharging port side unit 73b.

As shown in
In a state that one of the plurality of receiving portions 72 provided at the rotating body 68 is arranged at a position adjacent to the discharging port 74, the supplied area forming portion 78c is positioned between the receiving portion 72 located at a position adjacent to the discharging port 74 (hereinafter, this is sometimes referred to as “a delivery target receiving portion 72”) and the receiving portion 72 adjacent to the upper stream side of the positive rotational direction of the rotating body 68 than the delivery target receiving portion 72 (hereinafter, this is sometimes referred to as “an upper stream side receiving portion 72”). The supplied area forming portion 78c is constituted of a through-hole passing through the frame body 78 in the thickness direction thereof. Although the supplied area forming portion 78c may have any opening shape, the opening shape thereof is substantially circular in this embodiment.
In a state that one of the plurality of receiving portions 72 is arranged at the position adjacent to the discharging portion 74, the supplied area forming portion 78c forms a bottomed space having a bottom formed by an area corresponding to the thin-walled portion 68e in the surface (the front plate 68a) of the rotating body 68. This space constitutes an area (a supplied area 80) into which the medicines dispensed from the side of the medicine preparing and dispensing portion 20 are supplied before the medicines are received by each receiving portion 72. When the rotating body 68 is positively rotated after the medicines have been supplied into the supplied area 80 to move the upper stream side receiving portion 72 under the supplied area forming portion 78c, the medicines in the supplied area 80 are transferred into the upper stream side receiving portion 72. As described above, the bottom of the supplied area 80 can be opened and closed by relatively rotating the rotating body 68 with respect to the supplied area forming portion 78c and thus it is possible to transfer the medicines into the receiving portion 72 in a phase before the receiving portion 72 reaches the position adjacent to the discharging port 74.
In a state that one of the plurality of receiving portions 72 provided at the rotating body 68 is arranged at the position adjacent to the discharging port 74, the delivery area forming portion 78d is a portion for forming an area (a delivery area 82) containing this receiving portion 72 and the discharging port 74. The delivery area forming portion 78d has a side wall portion 78f surrounding an outer periphery of the supplied area 80. Further, the delivery area forming portion 78d has a partition wall portion 78g for separating between an area on the side of the receiving portion 72 constituting the supplied area 80 and an area on the side of the discharging port 74. A height of the partition wall portion 78g is lower than that of the side wall portion 78f.
The pre-absorbing position forming portion 78e is provided in a working area of the delivering device 64 described later. Further, the pre-absorbing position forming portion 78e is provided at a location whose surface is smooth in the frame body 78. Although the pre-absorbing position forming portion 78e may be provided at any location as long as the location satisfies these conditions, the pre-absorbing position forming portion 78e is provided in an area on the center side of the rotating body 68 in a state that the frame body 78 is attached in this embodiment.
The delivering device 64 is configured to individually and one by one hold the medicines in the receiving portion 72 (the delivery target receiving portion 72) reaching the position adjacent to the discharging port 74 and release the medicine in the discharging port 74 to perform an action (a delivery action) for delivering the medicines from the side of the medicine preparing and dispensing portion 20 to the side of the pre-packaging photographing portion 100. Although the delivering device 64 may be any device as long as it can perform the delivery action, the delivering device 64 is configured to include a driving portion 84 and a holding portion 86 as shown in
The driving portion 84 is configured to move the holding portion 86 between the receiving portion 72 (the delivery target receiving portion 72) and the discharging port 74. Although the driving portion 84 may be any portion as long as it can perform such an action, the driving portion 84 is constituted of a multi-joint robot such as a scalar robot and a manipulator in this embodiment. The driving portion 84 can move a delivering arm 84a between the receiving portion 72 (the delivery target receiving portion 72) and the discharging port 74.
The holding portion 86 is configured to perform an action (a holding action) for individually and one by one holding the medicines and an action (a hold releasing action) for releasing the medicine being held. Although the holding portion 86 may be any portion as long as it can perform the holding action and the hold releasing action, the holding portion 86 is configured to include an adsorbing portion 88, a suctioning device 90 and a discharging device 92 in this embodiment. The absorbing portion 88 includes a member obtained by providing a contacting portion 88b at a tip end portion of a hollow absorbing tube 88a. The suctioning device 90 and the discharging device 92 are connected to the absorbing tube 88a through pipes. Further, the contacting portion 88b is a portion which contacts with the medicine which is a holding target. It is preferable that the contacting portion 88b has elasticity in order to prevent the medicine from being broken or the like. In this embodiment, a pad-like portion formed from an elastic material such as rubber is used as the contacting portion 88b.
The suctioning device 90 is a device which is constituted of a pump or the like, for example, so as to provide suctioning force. Thus, when the suctioning device 90 is actuated, the suctioning force acts at the contacting portion 88b attached to the tip end of the absorbing tube 88a, thereby individually and one by one suctioning and holding the medicines. Further, by stopping the suctioning device 90, it is possible to release the suctioning force acting at the contacting portion 88b to release the medicine. Further, the discharging device 92 is constituted of a compressor or the like, for example, and connected to the absorbing tube 88a through the pipe. By actuating the discharging device 92, it is possible to discharge air in a direction opposite to a working direction of the suctioning force due to the suctioning device 90. Thus, by actuating the discharging device 92 when the medicine being held by the holding portion 86 is released, it is possible to apply discharging force to the medicine being held and actively release the medicine.

The medicine rolling and moving device 102 has rolling and moving units 110 and an opening-closing mechanism 140. Each rolling and moving unit 110 includes an operating mechanism for rolling and moving the medicines. In this embodiment, the plurality of rolling and moving units 110 (in the illustrated example, the number of the rolling and moving units 110 is six) are provided in a state that the rolling and moving units 110 are aligned in a circumferential direction of the disk-shaped rolling and moving portion rotating body 130 and the medicines which are inspection targets can be supplied into each of the rolling and moving units 110.
The rolling and moving unit 110 has an external shape as shown in
As shown in
As shown in
The fixed portion 118 is a member arranged so as to fit a position where an opening (not shown in the drawings) for discharging the medicines is formed in the rolling and moving rotating body 103. The fixed portion 118 includes a base portion constitution body 123, a first side constitution body 126 and a second side constitution body 128. The base portion constitution body 123 forms a bottom portion of the fixed portion 118 and is fixed on the rolling and moving rotating body 103. As shown in
As shown in
Further, as shown in
As shown in
The movable portion 122 is configured by providing an operating piece 122c so as to bridge between (inside) a pair of movable pieces 122a, 122a and integrating these pieces. Each of the movable pieces 122a, 122a is constituted of a plate-like body having a substantially triangle shape in a front view thereof. The seconds rotating roller 116 is provided between the movable pieces 122a, 122a. The second rotating roller 116 is rotatably supported by respectively connecting one end side and the other end side of the second rotational axis 116a to the movable pieces 122a, 122a. Further, the support axes 122b, 122b are respectively provided at the movable pieces 122a, 122a so as to protrude toward the outside. As described above, the support axes 122b, 122b are respectively inserted into the first side constitution body 126 and the second side constitution body 128. With this configuration, the movable portion 122 is supported so that the movable portion 122 can oscillate around the support axes 122b, 122b.
As shown in
Here, in a state that the first rotating roller 114 and the second rotating roller 116 are close to each other and the medicines which are the inspection targets can be arranged on them, an axial center position (a rotational center) of the second rotating roller 166 is positioned on the upper side than an axial center position (a rotational center) of the first rotating roller 114. This makes it possible to reliably rotate the medicines on the first rotating roller 114 and the second rotating roller 116.
Specifically, if the first rotating roller 114 and the second rotating roller 116 are arranged at the same or same level height as shown in
In contrast, in a case where one of the rollers 114, 116 (in this embodiment, the second rotating roller 116) is arranged at a higher position than the other one of the rollers 114, 116 as shown in
By taking the above-described configuration, the gravity center G of the medicine arranged on the rollers 114, 116 is in a state that the gravity center G is positioned on the side (the right side in the illustrated example) nearer to the roller 114 than the contact portion A between the roller 116 and the medicine and thus the rotation of the medicine is not interfered. Thus, by positioning the rotational center of one of the first rotating roller 114 and the second rotating roller 116 (in this embodiment, the second rotating roller 116) at a higher position than the rotational center of the other one of the first rotating roller 114 and the second rotating roller 116, it is possible to reliably rotate the medicine even if a roller whose diameter is relatively small is employed as the rollers 114, 116. Further, since it is possible to employ a small diameter roller as the rollers 114, 116, it is possible to reduce the size of the apparatus structure.
In addition to this matter, as shown in
Further, as described above, the first rotating roller 114 is configured to be the so-called radial-crown type or taper-crown type roller and the first rotating roller 114 expands toward the outer side of the radial direction from the both end sides of the axial line direction to the center side of the first rotational axis 114a. Thus, along with the rotation of the first rotating roller 114, propulsive force in a direction toward the substantially center portion of the axial line direction of the first rotating roller 114 acts to the medicine. Therefore, even if the medicine supplied into the rolling and moving unit 110 exists at a position away from the center portion of the axial line direction, the medicine is moved to the substantially center position of the axial line direction by the propulsive force caused by the rotation of the first rotating roller 144 and rotates at this position. Specifically, in a case of using the first rotating roller 114 of the radial-crown type, a speed difference occurs on the surface of the first rotating roller 114 being rotating due to a difference of the diameters of the center portion and the both end portions of the axial line direction. This makes it possible to obtain an effect (that is a so-called crown effect or an effect similar to the crown effect) that the medicine is moved to the center side where the speed is fast even if the medicine is supplied to a position deviated toward the both end sides of the first rotating roller 114.
As described above, by employing the radial-crown type roller as the first rotating roller 114, it is possible to rotate the medicine at a fixed position with respect to camera units 104a, 104b included in the medicine photographing device 104. This makes it possible to improve a photographing accuracy for the medicine by the camera units 104a, 104b. Further, by configuring the second rotating roller 116 to be the inverted-crown type roller curved along the first rotating roller 114, it is possible to prevent a clearance which can be a cause of the dropping of the medicine to be photographed from being formed between the rollers 114, 116.
On the other hand, when an operation for lifting up the operating portion 122d being in the substantially horizontal posture in the normal state is performed, the movable pieces 122a, 122a oscillate around the support axes 122b, 122b. Along with this movement, the second rotational axis 116a is guided by the guide grooves 134a, 134a of the guide portions 134, 134 provided in the base portion constitution body 123 and thus the second rotating roller 116 is lowered toward the diagonal lower side. This makes it possible to expand the clearance between the first rotating roller 114 and the second rotating roller 116, thereby dispensing the medicine on these rollers 114, 116 toward the lower side.
As shown in
The introducing portion 124 has a configuration (see
As shown in
Here, in a case where the introducing member 124b having the translucency as described above is connected to the bottom constitution portion 124a, there is a concern that light is reflected on a bottom (a contacting end 124f) of the introducing member 124b and this reflected light adversely affects the photographing for the medicines by the medicine photographing device 104. Specifically, due to an effect of the reflected light caused on the contacting end 124f, the introducing member 124b appears in the image photographed by the medicine photographing device 104 as a white artifact and thus it becomes difficult to distinguish the medicines from the introducing member 124b.
In order to address the above-described concern, in this embodiment, as shown in
Further, in this embodiment, an antistatic layer 124h made of an antistatic agent is provided on a surface of the colored layer 124g. This makes it possible to suppress static electricity caused when the medicine pivotally moves in the introducing member 124b with the antistatic layer 124h. In this regard, although the antistatic layer 124h is provided as another layer than the colored layer 124g in this embodiment, it may be possible to take a configuration in which the antistatic layer 124h is not provided and the colored layer 124g has an antistatic effect by mixing the antistatic agent into the colored layer 124g.
When the introducing member 124b is attached to the bottom constitution member 124a, the introduced area 124e is formed on the upper side of the first rotating roller 114 and the second rotating roller 116 as shown in
The reflecting member 124c is constituted of a plate-like body having gloss. As shown in
As shown in
The opening-closing driving source 140a is a portion for providing driving force in the opening-closing mechanism 140. Although the opening-closing driving source 140a may be constituted of any members, the opening-closing driving source 140a is constituted of a motor in this embodiment. The driving force transmission portion 140b is a portion for transmitting the driving force from the opening-closing driving source 140a to the working piece 140c.
The working piece 140c is a piece-like portion which is actuated by the driving force received from the opening-closing driving source 140a through the driving force transmission portion 140b. As shown in
The rotational amount detecting portion 140d is used for detecting a rotational amount of the rotational axis of the opening-closing driving source 140a. Although the rotational amount detecting portion 140d may be constituted of any member, the rotational amount detecting portion 140d is constituted of a rotary encoder in this embodiment.
The medicine photographing device 104 is used for photographing the medicines rolled and moved by the rolling and moving unit 110. Although the medicine photographing device 104 may be any device as long as it can photograph the medicines, the medicine photographing device 104 is configured to include a plurality of camera units 104a, 104b (the number of the camera units is two in the illustrated example) in this embodiment. As described above, the medicine photographing device 104 is attached to the attachment body 105 arranged on the upper side of the rolling and moving portion rotating body 103. The medicine photographing device 104 is provided at a position deviated from the position where the opening-closing mechanism 140 is arranged toward the upper stream side of the positive rotational direction of the rolling and moving portion rotating body 103 (this is the clockwise direction in the illustrated example). In this embodiment, in a state that the rolling and moving unit 110 remains at the position adjacent to the opening-closing mechanism 140, the camera units 104a, 104b are respectively arranged at positions (hereinafter, sometimes referred to as “photographing positions”) corresponding to positions where the two rolling and moving units 110, 110 adjacent to the upper stream side of the positive rotational direction of the rolling and moving portion rotating body 103 are arranged.
Although the camera units 104a, 104b are common in a point of including a camera 104c and a light source 104d, there is differences between them in the kind of the medicine to be photographed and a photographing method. Specifically, the medicine has two kinds containing one kind that the identification information is mainly attached with the engraved mark and another kind that the identification information is mainly attached with the print. The camera unit 104a is used for photographing the medicine to which the identification information is mainly attached with the engraved mark and the camera unit 104b is used for photographing the medicine to which the identification information is mainly attached with the print. As shown in
Further, trays 142 are respectively provided at positions on the lower side of the rolling and moving portion rotating body 103 and corresponding to the above-described photographing positions. The trays 142 are used for receiving powder or the like generated by rotating the medicine in the rolling and moving unit 110.
The packaging portion 150 is provided on the lower side of the above-described pre-packaging photographing portion 100. The packaging portion 150 includes a printing unit 152 for subjecting the packaging paper to printing and a package unit 154 for packaging the medicines with the packaging paper. The printing unit 152 includes a roll 156 around which the packaging paper which is two-folded is wound and a printer 158 for printing a name of the medicine, a dosage method or the like onto the surface of the packaging paper unwound from the roll 156 based on the inputted prescription data. The remaining amount of the packaging paper wound around the roll 156 is detected by a remaining amount detecting sensor 160 and a remaining amount signal is transmitted to the control part 200. Further, a paper stock-out sensor 162 is provided in the middle of the carrying path for the packaging paper unwound from the roll 156 and a stock-out signal is transmitted to the control part 200 at the time of detecting that the packaging paper becomes lack of stock.
The packaging unit 154 is used for applying heat to the packaging paper with heater rollers 164 (heating portions) to seal the packaging paper in order to form a packaging bag from the packaging paper. The packaging unit 154 includes the heater rollers 164 respectively arranged on both sides of the packaging paper carried from the diagonal upper direction toward the diagonal lower direction. The heater rollers 164 can rotate to carry the packaging paper and package the medicines for one package. A hopper 166 for supplying the medicines dispensed from the side of the pre-packaging photographing portion 100 for packaging the medicines is arranged on an upper stream side of the heater rollers 164 with respect to the carrying direction of the packaging paper. A tip end portion of the hopper 166 is inserted between the two-folded packaging paper in the middle of the carrying path due to the packaging unit 154. Further, a cutter 168 is provided on a downstream side of the heater rollers 164 with respect to the carrying direction of the packaging paper and thus it is possible to cut the packaging paper by desired packaging numbers. Furthermore, a carrying device 170 for carrying the cut packaging paper to a taken position is provided on a downstream side of the cutter 168 with respect to the carrying direction of the packaging paper.
In this regard, although the example of the packaging unit 154 in which the heater rollers 164 having the functions of carrying and sealing the packaging paper are provided is described in this embodiment, the present invention is not limited thereto. Namely, it may be possible to take a configuration in which the heater rollers 164 are not provided, the packaging unit 154 is configured to include a pair of heating bodies (heating portions) for heat-sealing the packaging paper by sandwiching the packaging paper from both sides and a carrying roller for carrying the packaging paper and the packaging bag is formed from the packaging paper by using these members.
The control part 200 transmits and receives a signal to and from a server in which a plurality of prescription data are stored. The control part 200 stores commands checked from the server into a buffer and controls the driving of the medicine preparing and dispensing portion 20 according to the commands to dispense the medicines corresponding to the prescription data. At the same time, the control part 200 controls the driving of the packaging portion 150. This makes it possible to allow the printing unit 152 to print dosage information or the like related to the medicines to be dispensed onto the packaging paper and drive the packaging unit 154 to package the medicines for every one dose. Further, it is possible to allow a display device such as the touch panel 14a to display a result of the inspection for the medicines performed as described later. In this regard, a data table constituted of medicine information (medicine identification information, a medicine name, a medicine code, a dosage method, an effect, a medicine image and the like) is stored in a storage portion of the server in addition to the prescription data. These kinds of information may be stored in a storage portion of the control portion 200.
Each portion 224 of the medicine packaging apparatus 10 is connected to the control portion 200 so that each portion of the medicine packaging apparatus 10 can perform one or both of receiving and transmitting a signal. In this embodiment, the control part 200 is connected so as to receive and transmit a signal from and to the medicine preparing and dispensing portion 20, the individually supplying portion 60, the inspection unit portion 50 and the packaging portion 150.
The control part 200 includes an action control part 210 and is configured to use the action control part 210 to appropriately control an action of each of the medicine preparing and dispensing portion 20, the individually supplying portion 60, the inspection unit portion 50 and the packaging portion 150. In this embodiment, in order to realize distinguishing actions in the medicine packaging apparatus 10, the control part 200 includes an individually supplying control part 220, a reading control part 230 and an inspection processing part 240 in addition to the action control part 210. Hereinafter, each part constituting the action control part 210 will be further described in detail.
The individually supplying control portion 220 is used for controlling an action of the individually supplying portion 60. The individually supplying control part 220 includes a rotating body control part 222, an arrangement deriving part 224, a delivery action control part 226 and an action confirmation control part 228. In this regard, each part constituting the individually supplying control part 220 is not necessarily essential and it may be possible to take a configuration in which some of parts are omitted or any other configurations are added thereto as long as it can perform the action for individually and one by one supplying the medicines to the side of the pre-packaging photographing portion 100 in the individually supplying portion 60.
The rotating body control part 222 is used for controlling an action of the rotating body 68. In order to prepare for the receiving of the medicines from the manually distributing portion 24 to each receiving portion 72, the rotating body control part 222 performs a control for rotating the rotating body 68 so that the receiving portion 72 is arranged at a position suitable for receiving the medicines. Further, in order to prepare for the delivery action (the action for delivering the medicines received from the side of the medicine preparing and dispensing portion 20 to the side of the pre-packaging photographing portion 100 with the delivering device 64), the rotating body control part 222 performs a control for moving the receiving portion into the working area of the delivering device 64. Regarding the control related to the movement of the receiving portion 72, the rotating body control part 222 first rotates the rotating body 68 in the positive direction so that the receiving portion 72 rotates to respectively reach a position over a predetermined position (a discharging port adjacent position) adjacent to the discharging port 74. After that, the rotating body control part 222 performs a control for inversely rotating the rotating body 68 so that the receiving portion 72 returns to the discharging port adjacent position.
The arrangement deriving part 224 is used for deriving an arrangement of the medicines in the receiving portion 72 reaching to the discharging port adjacent position under the control of the rotating body control part 222. The arrangement deriving part 224 allows the receiving photographing portion 94 to photograph the receiving portion 72 with turning on the illuminating portion 96 to illuminate the receiving portion 72 from the lower side after the receiving portion 72 has reached the discharging port adjacent position. The arrangement deriving part 224 analyzes the image date obtained by the receiving photographing portion 94 to find out the locations where the medicines appear as the shadows. Based on this analysis result, the arrangement deriving part 224 derives the arrangement of the medicines in the receiving portion 72.
The delivery action control part 226 is used for performing an execution control for the delivery action performed with using the delivering device 64 and the like. Here, although various execution methods can be considered as the execution control for the delivery action, a method of combining a plurality of actions such as an arm driving action, a suctioning action and a separating action is performed as the execution method for the delivery action in this embodiment. Here, the arm driving action represents an action for driving the delivering arm 84a of the delivering device 64, the suctioning action represents an action for allowing the holding portion 86 of the delivering device 64 to suction and hold the medicine and the separating action represents an action for separating the medicine which has been suctioned and held from the holding portion 86. In this regard, the delivery action may be any action as long as it can deliver the medicines to the side of the pre-packaging photographing portion 100 with using the delivering device 64 and it may be also possible to omit some of actions from the delivery action and add other actions to the delivery action.
The delivery action control part 226 is used for performing an execution control for the arm driving action. The delivery action control part 226 moves the delivering arm 84a based on the analysis result obtained by the arrangement deriving part 224. This makes it possible to move the delivering arm 84a so that the holding portion 86 reaches the position where the medicine is arranged. Further, after the holding portion 86 has held the medicine, it is possible to lift up the medicine to move the medicine to the side of the discharging port 74 by actuating the delivering arm 84a with the delivery action control part 226. At this time, the delivery action control part 226 actuates the delivering arm 84a with limiting the working range so that the medicine held by the holding portion 86 is moved in an area surrounded by the frame body 78 within a range not exceeding a height of the side wall portion 78f of the frame body 78.
The action confirmation control part 228 is used for performing an action confirmation for each portion constituting the individually supplying portion 60. Although the action confirmation control part 228 can be configured to perform various confirmation actions, the action confirmation control part 228 is configured to perform a confirmation action combining an action confirmation for the suctioning device 90 and an attachment confirmation for the frame body 78 before the delivery action is performed in this embodiment. Specifically, the action confirmation control part 228 moves the holding portion 86 attached to the delivering arm 84a to a predetermined pre-suctioning position deviating from the location where the medicine is arranged before the delivery action is performed to allow the contacting portion 88b to make contact and actuates the suctioning device 90. In this embodiment, the suctioning device 90 is actuated with allowing the contacting portion 88b to contact with the predetermined suctioning position forming portion 78e arranged in the frame body 78. The action confirmation control part 228 confirms whether or not a certain level of the suctioning force is provided by such actions. With this configuration, in a case where it is confirmed that the certain level of the suctioning force is provided, the action confirmation control part 228 confirms that the suctioning device 90 is in a normal state and the frame body 78 is correctly attached. On the other hand, in a case where it is not confirmed that the certain level of the suctioning force is provided, the action confirmation control part 228 confirms that one or both of a bad condition of the suctioning device 90 and an attachment failure of the frame body 78 has occurred.
The reading control part 230 is used for performing an action control for the pre-packaging photographing portion 100 to read the identification information attached to the medicine. The reading control part 230 includes a rolling and moving control part 232, a photographing control part 234, a discharging control part 236 and the like. In this regard, each part constituting the reading control part 230 is not necessarily essential and it may be possible to omit some of them and add other configurations as long as it can perform the action for reading the identification information attached to the medicine.
The rolling and moving control part 232 is used for performing an action control for the rolling and moving unit 110 constituting the medicine rolling and moving device 102. The rolling and moving control part 232 performs a rotation control of the rolling and moving portion rotating body 103 to perform a control (a movement control) for moving each rolling and rolling unit 110 to a proper position in sequence. Specifically, each rolling and moving unit 110 is moved to the proper position for receiving the medicines which are the inspection targets and a control for moving the rolling and moving units 110 in which the medicines have been received to the position where the medicine photographing device 104 is provided is performed in sequence at the same time. Further, the rolling and moving control part 232 actuates the first rotating roller 114 and the second rotating roller 116 of the rolling and moving unit 110 reaching the position where the medicine photographing device 104 is provided to perform a control (a rolling and moving control) for rolling and moving the medicine on these rollers 114, 116. The rolling and moving control part 232 rolls and moves the medicines over a substantially entire of a time period when the image of the medicine is photographed by the photographing control part 234 described later.
The photographing control part 234 performs an action control for the medicine photographing device 104 to photograph the image of the medicine rolled and moved along with the actuation of the first rotating roller 114 and the second rotating roller 116. The image data obtained by this control is outputted to the inspection processing part 240 described later and used for performing the inspection process.
The discharging control part 236 is used for performing an action control for the opening-closing mechanism 140 to discharge the medicine whose image has been already photographed under the above-described control of the photographing control part 234 from the rolling and moving unit 110. At the time of discharging the medicine from the rolling and moving unit 110, the discharging control part 236 actuates the opening-closing driving source 140a to allow the working piece 140c to perform an action for lifting up the operating piece 122c of the rolling and moving unit 110. This makes it possible to expand the clearance between the first rotating roller 114 and the second rotating roller 116 in the rolling and moving unit 110 to drop down the medicine between the rollers 114, 116. Due to this control, the medicine is discharged to the side of the packaging portion 150.
The inspection processing part 240 performs a process for obtaining the identification information such as the engraved mark and the print attached to the medicine with using the image data obtained from the photographing control part 234. Further, the inspection processing part 240 identifies the medicine matching with the identification information obtained from a database stored in a server or the like based on the identification information obtained based on the image data. With this configuration, the inspection processing part 240 identifies the medicine information on the medicine which is actually dispensed from the identification information obtained based on the photographed image data of the medicine. Further, based on the prescription data, the medicine information on the medicine to designated to be packaged is identified. The inspection processing part 240 compares the medicine information derived based on the image data with the medicine information derived based on the prescription data. As a result, in a case both of the medicine information match with each other, it is determined that the medicine is appropriately dispensed. On the other hand, in a case where both of the medicine information do not match with each other, it is determined that the dispensing of the medicine is improper. In the case where it is determined that the dispensing of the medicine is proper, there is no problem even if the dispensing of the medicine is continued as it is. On the other hand, in the case where it is confirmed that the dispensing of the medicine is improper, it is preferable to perform an alert action such as an action for displaying a message indicating this error on the display device such as the touch panel 14a or emitting an alert sound, for example.
In this regard, it is preferable that the result of the above-described inspection (image inspection) based on the image data is displayed not only in the case of determining that the dispensing is improper but also in the case of determining that the dispensing is proper. Further, at the time of displaying the result of the image inspection, it may be possible to output one or more images obtained by the camera units 104a, 104b as data for providing supplementation of the inspection result. Specifically, an image of the front surface or the rear surface of the medicine utilized for obtaining the identification information on the medicine may be outputted as data for providing supplementation of the inspection result.
Although an aspect of displaying the result of the image inspection on the displaying device such as the touch panel 14a may be any kinds of aspects, it may be possible to take a configuration in which the image data of the medicines is displayed so that the medicines can be distinguished in a package unit (dosage time) packaged in the packaging portion 150, for example. Further, the image data of the medicines displayed in the package unit may be listed according to a predetermined order of the kinds of the medicines. By taking such a configuration, it is possible to easily confirm the inspection result based on the displayed image data. As a result of the inspection, in a case where it is determined that the improper dispensing of the medicine is performed, it is preferable that a message indicating that the error has occurred is informed by changing a color of the image of the medicine displayed on the touch panel 14a or displaying the image of the medicine with a blinking state on the touch panel 14a.
More specifically, for example, in a case where the inspection is performed for the medicine dispensed according to the prescription data as shown in
Here, with referring to the example of the image displaying aspect indicating the inspection result shown in
In this regard, although the example in which the medicine is displayed with the simplified graphic such as the mark “∘” is described in
Subsequently, description will be given to the action of the medicine packaging apparatus 10. In this regard, the inspection process for the medicine performed before the medicines are packaged which is the main distinguishing part of the present invention, will be described in the following description with emphasis.
The medicines dispensed from the medicine preparing and dispensing portion 20 according to the prescription data reach the pre-packaging photographing portion 100 through a path as shown in
More specifically, the medicines dispensed from the manually distributing portion 24 are introduced into the receiving portions 72 of the individually supplying portion 60. In the individually supplying portion 60, the rotating body 68 is rotated and the medicines dispensed from the manually distributing portion 24 for one box are introduced into each of the empty receiving portions 72 in sequence. When the receiving portion 72 in which the medicines have been supplied reaches the position adjacent to the discharging port 74 along with the rotation of the rotating body 68, the action (the delivery action) for individually and one by one delivering the medicines from the receiving portion 72 toward the discharging port 74 is performed by the delivering device 64.
Even more specifically, the medicines dispensed from the manually distributing portion 24 are supplied into an area eccentrically located on the side of the rotational center of the rotating body 68 in the receiving portion 72 of the individually supplying portion 60. After that, at the time when the rotating body 68 is rotated and the receiving portion 72 in which the medicines have been supplied reaches the position adjacent to the discharging port 74, the rotating body is rotated in the positive direction so that the receiving portion 72 is first moved to a position over a predetermined position (a discharging port adjacent position) adjacent to the discharging port 74 under the control of the rotating body control part 222. After that, the rotating body 68 is rotated in the inverted direction so that the receiving portion 72 returns to the discharging port adjacent position. By performing such an action, the medicines in the receiving portion 72 are separated from the inner circumferential surface 72d of the receiving tube 72c. Further, since the cross-sectional shape of the receiving portion 72 is non-circular (in this embodiment, the cross-sectional shape is the substantially polygonal shape), the medicines are soon stopped after the medicines are dispersed in the receiving portion 72.
When the receiving portion 72 reaches the discharging port adjacent position as described above, the arrangement of the medicines in the receiving portion 72 is found out under the control of the arrangement deriving part 224. Although the method for deriving the arrangement of the medicines may be any method, an analysis process for finding out shadow portions in the image data obtained by photographing the receiving portion 72 by using the receiving photographing portion 94 with illuminating the receiving portion 72 from the lower side by using the illuminating portion 96 is performed to derive the arrangement of the medicines based on positions of the shadows in this embodiment. When the receiving portion 72 returns to the discharging port adjacent position, the medicines are separated from the inner circumferential surface 72d of the receiving tube 72c as described above. Thus, since shadow images of the medicines appear at positions away from the receiving tube 72c, it is possible to accurately identify the positions of the medicines.
When the arrangement of the medicines in the receiving portion 72 reaching the discharging port adjacent position is derived as described above, the delivery action is performed based on this result under the control of the delivery action control part 226 by the delivering device 64 and the like. Although the delivery action may be performed with any method, the delivery action is performed after an action for confirming that any cause of action failure does not exist in each portion constituting the individually supplying portion 60 is performed by the action confirmation control part 228 in advance in this embodiment.
Specifically, the delivering arm 84a is moved to the pre-suctioning position provided in the frame body 78 under the control of the action confirmation control part 228 to allow the contacting portion 88b to make contact with the pre-suctioning position and actuate the suctioning device 90. With this configuration, it is confirmed that an action failure of the suctioning device 90, an attachment failure of the frame body 78 or the like does not occur. After that, the delivering arm 84a is actuated by the delivery action control part 226 and the holding portion 86 of the delivering device 64 is moved to the location where the medicine is arranged in the receiving portion 72. Further, by actuating the suctioning device 90, the medicine is suctioned and held by the holding portion 86.
After that, the holding portion 86 which keeps suctioning and holding the medicine is moved to the side of the discharging port 74 in the frame body 78. When the holding portion 86 reaches the discharging port 74, the delivering arm 84a is stopped and the medicine suctioned and held is released from the holding portion 86. At this time, by stopping the suctioning device 90, closing a valve provided in a path from the suctioning device 90 to the holding portion 86 or the like, the suctioning device 90 becomes in a state that the suctioning force is not applied to the medicine. In addition, by actuating the discharging device 92, discharging air onto the medicine being held by the holding portion 86 in the direction opposite to the working direction of the suctioning force and the like to apply the discharging force to the medicine. This makes it possible to reliably release the medicine from the holding portion 86 and discharge the medicine to the side of the discharging port 74. In this regard, although the example in which the discharging device 92 is actuated at the time of releasing the medicine is described in this embodiment, it may be possible to take a configuration in which the discharging device 92 is not provided and the discharging force is not applied or a configuration in which the discharging device 92 is actuated only in a case where the discharging device 92 is considered to be necessary.
By repeating the action for suctioning the medicine in the frame body 78 and releasing the medicine after the medicine has been moved to the side of the discharging port 74 as describe above, it is possible to individually and one by one supply all of the medicines supplied from the manually distributing portion 24 into the frame body 78 to the side of the pre-packaging photographing portion 100 through the discharging port 74. The medicines dispensed through the discharging port are one by one supplied into each medicine rolling and moving device 102 which is in the empty state through the opening 105a provided in the attachment body 105 of the pre-packaging photographing portion 100, respectively.
Further, the medicines dispensed from the cassette dispensing portion 22 are transmitted to the side of the pre-packaging photographing portion 100 through a pipe or the like not shown in the drawings. After that, these medicines are one by one supplied into each medicine rolling and moving device 102 which is in the empty state through the hopper 105b connected to the attachment body 105.
On the other hand, the action control for the rolling and moving unit 110, the medicine photographing device 104 and the opening-closing mechanism 140 are performed on the side of the pre-packaging photographing portion 100 under the control of the reading control part 230 in order to receive the medicines from the manually distributing portion 24 or the cassette dispensing portion 22. Specifically, in order to allow the medicines to be received in the pre-packaging photographing portion 100, the rolling and moving control part 232 pivotally moves the rolling and moving portion rotating body 112 to reach the empty rolling and moving unit 110 in which the medicines are not supplied to the lower side of the discharging port 74. After that, the rolling and moving portion rotating bodies 112 are rotated in sequence and the rolling and moving unit 110 in which the medicines have been supplied is moved to the position where the medicine photographing device 104 is arranged.
When the rolling and moving unit 110 reaches the position of the medicine photographing device 104 after the medicines have been supplied to the rolling and moving unit 110 as described above, the driving force applying portion 120a is actuated based on the control of the rolling and moving control part 232 to perform a control (a rolling and moving control) for rotating the first rotating roller 114 and the second rotating roller 116. Along with this operation, the medicine existing on the rollers 114, 116 is moved to the substantially center portions of the axial lines of the rollers 114, 116 with being rotated. While the medicine is being rotated as described above, the control for actuating the medicine photographing device 104 is performed by the photographing control part 234 to obtain the image date of the medicine being rotating on the rollers 114, 116.
When the image data of the medicine which is the inspection target is obtained as described above, an action for dispensing the medicine from the rolling and moving unit 110 toward the packaging portion 150 is performed under the control of the discharging control part 236. Specifically, the discharging control part 236 actuates the motor constituting the opening-closing driving source 140a by a predetermined amount to incline the tip end side of the working piece 140c toward the upper side. Along with this action, the working piece 140c contacts with the operating portion 122d of the operating piece 122c provided on the front side of the rolling and moving unit 110 from the lower side and thus the operating piece 122c becomes in a state that the operating piece 122c is lifted up. This makes it possible to move the second rotating roller 116 in the direction separating away from the first rotating roller 114 and thus expand the clearance between the rollers 114, 116, thereby dispensing the medicine existing on the rollers 114, 116 from the rolling and moving unit 110.
When the dispensing of the medicine finishes as described above, the discharging control part 236 further rotates the motor constituting the opening-closing driving source 140a. With this action, the working piece 140c inclining toward the upper side returns to a substantially horizontal posture. Along with this movement, the operating portion 122d of the operating piece 122c also returns to a substantially horizontal posture due to its own weight and the fixed portion 122e on the side of the first side constitution body 126 becomes in a state that the fixed portion 122e is absorbed and fixed with respect to the magnet 126a provided on the front side of the first side constitution body 126. With this configuration, the second rotating roller 116 returns to a state close to the first rotating roller 114 and thus the medicine can be arranged on the rollers 114, 116.
When the image data of the medicine which is the inspection target is obtained as described above, the inspection process is performed under the control of the inspection processing part 240 as described above. Namely, whereas the identification information such as the engraved mark on the medicine which is the inspection target is found out from the image date and the medicine information is identified, the identification information on the medicine to be inspected is obtained from the prescription data. Then, these kinds of the identification information are compared with each other and a judge for determining whether or not the medicine is appropriately dispensed according to the prescription data is performed. The judge result is indicated with an appropriate method such as the displaying means such as the touch panel 14a, sound, blinking of a lamp or the like.
The medicines whose inspections have finished as described above are discharged into the hopper 166 provided between the inspection unit portion 50 and the packaging portion 150 and stored in the hopper 166 in sequence. Further, the medicines for one dose (one dose unit) are stored and the medicines are dispensed from the hopper 166 toward the packaging portion 150 if the inspection result has no problem. The medicines dispensed to the packaging portion 150 are packaged for every one dose by the packaging unit 154 with the packaging paper on which corresponding dosage information (a name of the medicine, a dosage method or the like) is printed by the printing unit 152. The packaging by the packaging unit 154 may be appropriately performed. For example, the packaging may be automatically performed or a confirmation button is once displayed and the packaging is performed under a condition that the confirmation button is pushed. This makes it possible to reliably supply and package the medicines remaining in the hopper 166 into one bag to which the printing is performed. On the other hand, if a problem occurs as the result of the inspection, a message indicating that an error has occurred may be printed on the corresponding one bag or the printing of the message may be performed on a subsequent packaging paper continuing the one bag if the printing has been performed to the one bag.
In this regard, the medicine packaging apparatus 10 of the present invention may be configured so that the medicines for one dose (in the one dose unit) are stored in the hopper 166 and the medicines are dispensed from the hopper 166 to the packaging portion 150 after the result of the inspection is obtained as described above or may be configured so that the medicines for one dose are not stored in the hopper 166 and the medicines are dispensed toward the packaging portion 150. Further, the packaging portion 150 may be configured to include a blowing portion 300 and a post-packaging information writing portion 320 described later. Namely, the packaging portion 150 may be configured so that the medicines are once packaged without waiting the inspection result for the medicines and then the information on the inspection result is written onto the packaging bag after the medicines have been packaged with using the post-packaging information writing portion 320 described later.
As described above, in the medicine packaging apparatus 10 of this embodiment, the medicines received from the side of the medicine preparing and dispensing portion 20 to the receiving portion 72 by the individually supplying portion 60 are individually held by the delivering device 64 and can be supplied to the side of the pre-packaging photographing portion 100. This makes it possible to accurately read the identification information on the medicines supplied through the individually supplying portion 60 with the pre-packaging photographing portion 100, thereby contributing the improvement of the inspection performance.
Since the medicine packaging apparatus 10 of this embodiment is configured so that the medicines supplied into the manually distributing portion 24 are supplied to the pre-packaging photographing portion 100 through the individually supplying portion 60, it is possible to reliably and one by one supply the medicines to the pre-packaging photographing portion 100 even if the plurality of medicines are dispensed from the manually distributing portion 24 at one time. This makes it possible to reliably and one by one read the identification information of the medicines in the pre-packaging photographing portion 100. On the other hand, the medicines dispensed from the cassette dispensing portion 22 including the medicine cassettes 32 which can individually dispense the medicines stored therein are supplied to the pre-packaging photographing portion 100 with the path bypassing the individually supplying portion 60 and inspected. Thus, in the medicine packaging apparatus 10 of this embodiment, the process in the individually supplying portion 60 can be omitted for the medicines, which are not necessarily separated one by one, such as the medicines dispensed from the medicine cassette 32 and thus it is possible to improve the efficiency and the speed of the inspection process.
In this regard, although the medicines dispensed from the cassette dispensing portion 22 are supplied to the pre-packaging photographing portion 100 through the path bypassing the individually supplying portion 60 in this embodiment, the present invention is not limited thereto and it may be possible to also supply the medicines dispensed from the cassette dispensing portion 22 to the pre-packaging photographing portion 100 through the individually supplying portion 60. Further, although the above-described medicine packaging apparatus 10 is configured to supply all of the medicines dispensed from the manually distributing portion 24 to the pre-packaging photographing portion 100 through the individually supplying portion 60, the present invention is not limited thereto. Specifically, the medicine packaging apparatus 10 may be configured to supply the medicines to the pre-packaging photographing portion 100 through the individually supplying portion in a case where the plurality of medicines are collectively dispensed and may be configured to directly supply the medicines to the pre-packaging photographing portion 100 without passing through the individually supplying portion 60 in a case where the medicine packaging apparatus 10 is used in an operation that the medicines are one by one dispensed from the manually distributing portion 24.
As described above, the medicine packaging apparatus 10 of this embodiment is configured so that the delivering device 64 includes the suctioning device and the medicines can be one by one suctioned and held by the suctioning device 90. Thus, it is possible to reliably, one by one and individually hold and supply the medicines supplied to the individually supplying portion 60 to the side of the pre-packaging photographing portion 100. In this regard, the delivering device 64 is not necessarily configured to individually hold the medicines with using the suctioning force as described above and may be configured to one by one grip the medicines, for example.
Further, in the medicine packaging apparatus 10 of this embodiment, although the example in which the contacting portion 88b is provided at the tip end of the absorbing tube 88a is described as the absorbing portion used for absorbing the medicines in the delivering device 60, the shape and the like of the contacting portion 88b can be appropriately modified. Specifically, although the above-described contacting portion 88b may be configured to be constituted of the pad portion 88c as shown in
Further, the medicine packaging apparatus 10 of this embodiment is configured so that the delivering device 64 includes the discharging device 92 in addition to the suctioning device 90 and discharges air at the time of releasing the medicine. By taking such a configuration, it becomes possible to even more reliably release the medicine held by the delivering device 64. In this regard, although the example in which the delivering device 64 includes the discharging device 92 is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in which the delivering device 64 does not include the discharging device 92.
As described above, the medicine packaging apparatus 10 is configured so that the delivering device includes the contacting portion 88b contacting with the medicine at the time of the delivery actin and performs the action (the pre-suctioning action) for allowing the contacting portion 88b to contact with the pre-absorbing position forming portion 78e which is not related to the suctioning for the medicine to apply the suctioning force before the delivery action is performed. By allowing the delivering device 64 to perform such an action, it is possible to perform a pre-check for confirming whether or not the proper suctioning force is caused for holding the medicine in the delivery device 64. Further, by providing the pre-absorbing position 74e in the frame body 78, the pre-absorbing action is also utilized for confirming an arrangement status of the frame body 78. With this configuration, it becomes unnecessary to provide a sensor or the like for confirming the attachment status of the frame body 78 and thus it is possible to contribute to simplification of the device structure or action. In this regard, although the example in which the pre-suctioning action is performed is described in this embodiment, the medicine packaging apparatus 10 may be configured not to perform the pre-suctioning action. Further, although the example in which the pre-absorbing position forming portion 78e is provided in the frame body 78 is described, other portions may be defined as the pre-absorbing position forming portion 78e.
The medicine packaging apparatus 10 of this embodiment is configured so that the medicine is moved from the side of the receiving portion 72 to the side of the discharging port 74 in the area lower than the upper end of the frame body 78 provided so as to surround the receiving portion 72 and the discharging port 74. With this configuration, even if the medicine drops down from the delivering device 64 during the delivery action by any possibility, the dropped medicine remains inside the frame body 78 and it is possible to prevent a failure that the medicine drops down to an unexpected location or the like. In this regard, the example in which the medicine is moved within the range of the height of the frame body 78 to prepare for the drop of the medicine during the delivery action is described in this embodiment, the present invention is not limited thereto. Specifically, it may be possible to take a configuration in which the medicine is moved over the height of the frame body 78 or the frame body 78 itself is not provided. In this regard, even in a case of taking such a configuration, it is preferable to take any way for preparing for the drop of the medicine during the delivery action.
In the medicine packaging apparatus 10, the bottom portion of the receiving portion 72 is formed from the translucent material having the translucency. Further, the arrangement of the medicines in the receiving portion 72 is derived by the arrangement deriving part 224 based on the image data obtained by photographing the receiving portion 72 from the upper side by the receiving photographing portion 94 with illuminating the receiving portion 72 from the lower side by the illuminating portion 96 and the medicines can be held by actuating the delivering device 64. By taking such a configuration, it is possible to precisely find out the arrangement of the medicines supplied to the receiving portion 72 and accurately perform the delivery action due to the delivering device 64. In this regard, the example in which the above-described portion is employed as means for finding out the arrangement of the medicines for delivering the medicines is described in this embodiment, the present invention is not limited thereto and any other replaceable method may be employed.
As described above, the medicine packaging apparatus 10 is configured so that the collectively discharging mechanism 73 is provided at the individually supplying portion 60 and it becomes possible to collectively discharge the medicines in the receiving portion 72. This makes it possible to rapidly discharge the medicines in the receiving portion 72 in a case where the medicines introduced into the receiving portion 72 need to be collected, in a case where the packaging is stopped while the medicines are one by one discharged to the side of the pre-packaging photographing portion 100 or the like. In this regard, the example in which the collectively discharging mechanism 73 is provided at the individually supplying portion 60 is described in this embodiment, it may be possible to take a configuration in which the collectively discharging mechanism 73 is not provided. Further, the collectively discharging mechanism 73 may be any other structure which can be replaced with the above-described structure.
The medicine packaging apparatus 10 of this embodiment is configured so that the plurality of receiving portions 72 are arranged on the rotating body along the circumferential direction thereof and the delivery action for the medicines in the receiving portion 72 arranged in the working area of the delivering device 64 can be performed along with the rotation of the rotating body 68. With this configuration, it is possible to prepare the medicines supplied from the side of the medicine preparing and dispensing portion 20 into the plurality of receiving portions 72 in sequence and moves the rotating body 68 into the working are of the delivering device 64 to perform the delivery action. This makes it possible to efficiently perform the action for individually and one by one supplying the medicines to the side of the pre-packaging photographing portion 100 in the individually supplying portion 60.
In this regard, although the example in which the plurality of receiving portions 72 are provided is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in which a single receiving portion 72 is provided. Further, the example in which the plurality of receiving portions 72 are moved into the working area of the delivering device 64 in sequence by the rotating body 68 is described, the present invention is not limited thereto and it may be possible to take a configuration in which each receiving portion 72 is moved into the working area of the delivering device 64 by moving means other than the rotating body 68. Further, it may be possible to take a configuration in which the plurality of receiving portions 72 are provided and a plurality of delivering devices 64 are also provided to enable the delivery action without moving the receiving portions 72 or a configuration in which the delivering device 64 is configured to be moved with respect to the plurality of receiving portions 72 to relatively move the delivering device 64 and each receiving portion 72 for enabling the delivery action.
The medicine packaging apparatus 10 of this embodiment is configured so that the medicines supplied from the side of the medicine preparing and dispensing portion 20 are supplied to the position on the side of the axial center position of the rotating body 68 in the receiving portion 72. This makes it possible to individually disperse the medicines in the receiving portion 72 along with the rotation of the rotating body 68 and thus it becomes possible to smoothly perform the action for one by one holding and delivering the medicines with the delivering device 64. In this regard, the position for supplying the medicines with respect to the receiving portion 72 is not limited to the above-described position, the medicines may be supplied to any other location.
Further, in the medicine packaging apparatus 10, the rotating body 68 is rotated over the predetermined position where the receiving portion 72 should be arranged at the time of delivering the medicines when the rotating body 68 is rotated to prepare for the delivery action and then the rotating body 68 is reversely rotated so as to return the predetermined position. With this configuration, the medicines are likely to be in the state that the medicines are separated from the wall surface constituting the receiving portion 72 when the receiving portion 72 reaches the above-described predetermined position. Thus, by actuating the rotating body 68 as described above, it is possible to make the action for one by one holding the medicines with the delivering device 64 much easier. In this regard, the medicine packaging apparatus 10 is not necessarily configured to actuate the rotating body 68 as described above.
The medicine packaging apparatus 10 of this embodiment is configured so that the receiving portion 72 has the receiving area 72b on the inner side of the inner circumferential surface 72d and the cross-sectional shape of the receiving area 72b is non-circular (in this embodiment, the cross-sectional shape is substantially polygonal). Namely, a curved portion is provided on the inner circumferential surface 72d. With this embodiment, the medicines supplied into the receiving area 72b become unlikely to be rotated along the inner circumferential surface 72d. Thus, it is possible to suppress the time duration until the medicines are rotated and then stopped after the medicines are received in the receiving portion 72 to a minimum. In this regard, the medicine packaging apparatus 10 is not necessarily configured so that the cross-sectional shape of the receiving area 72b is non-circular (in this embodiment, the cross-sectional shape is substantially polygonal) or the inner circumferential surface 72d is curved. For example, the medicine packaging apparatus 10 may be configured so that the cross-sectional shape of the receiving area 72b is circular.
The medicine packaging apparatus 10 of this embodiment is configured so that the pre-packaging photographing portion 100 can photograph the medicines by the medicine photographing device 104 with rolling and moving the medicines by the medicine rolling and moving device 102 to obtain the identification information attached to the medicines by using its image data with the reading control part 230. Namely, in the medicine packaging apparatus 10, it is possible to read the identification information based on the photographed image without intervening the packaging paper or the like. Further, in the medicine packaging apparatus 10, the medicines can be photographed by the medicine photographing device 104 with rolling and moving the medicines by the medicine rolling and moving device 102. Thus, it is possible to read the identification information without being affected by the postures of the medicines at the time of supplying the medicines to the pre-packaging photographing portion 100. Thus, according to the medicine packaging apparatus 10, it is possible to improve the inspection process accuracy for the medicines.
Further, in the medicine packaging apparatus 10, the first rotating roller 114 and the second rotating roller 116 arranged side by side are included as the medicine rolling and moving device 102 and the first rotating roller 116 and the second rotating roller 116 are rotated in the same direction at the time of reading the identification information. This makes it possible to roll and move the medicine regardless of the size and the shape of the medicine and photograph the image in a state of allowing the identification information to be recognized with the medicine photographing device 104. In this regard, the example in which the first rotating roller 114 and the second rotating roller 116 are used as the medicine rolling and moving device 102 for rolling and moving the medicine is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in which the medicine is rolled and moved by any other configuration.
Further, the medicine packaging apparatus 10 is configured so that the cross-sectional shape of the introduced area 124e into which the medicines are introduced is non-circular (in this embodiment, the cross-sectional shape is substantially polygonal) in the medicine rolling and moving device 102. Thus, the medicines supplied into the introduced area 124e are not likely to move along the inner circumferential surface of the medicine rolling and moving device 102 and thus it is possible to suppress the time duration while the medicines move along the inner circumferential surface of the medicine rolling and moving device 102 to a minimum. This makes it possible to smoothly start the operation such as the reading process for the identification information. In this regard, the example in which the cross-sectional shape of the introduced area 124e is non-circular is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in that the cross-sectional shape of the introduced area 124e is modified so as not to provide the curved portion on the inner circumferential surface such as a circular shape, for example.
The above-described medicine packaging apparatus 10 of this embodiment is configured so that the medicine rolling and moving device 102 has the introducing portion 124 and the introduced area 124e into which the medicines are supplied is provided inside the introducing portion 124. Further, the introducing portion 124 is configured so that the bottom constitution member 124a and the introducing member 124b are provided as the constitution bodies and the bottom constitution member 124a and the introducing member 124b are connected to each other in the vertical direction so that the end surfaces of the bottom constitution member 124a and the introducing member 124b contact with each other. Further, the end surfaces of the bottom constitution member 124a and the introducing member 124b have the dark color. This makes it possible to prevent light from entering into the introduced area from the connecting portion between the bottom constitution member 124a and the introducing member 124b, thereby avoiding the image obtained by the medicine photographing device 104 from being unclear. In this regard, although the example in which the end surfaces constituting the connecting portion between the bottom constitution member 124a and the introducing member 124b have the dark color to prevent the light from entering into the introduced area 124e is described in this embodiment, the present invention is not limited thereto and may be configured to obtain the same effect with any other configuration.
Further, the medicine packaging apparatus 10 is configured so that the first rotating roller 114 and the second rotating roller 116 arranged side by side in the medicine rolling and moving device 102 have the dark color. This makes it possible to clearly distinguish the medicines from the first rotating roller 114 and the second rotating roller 116 in the image obtained by photographing the medicines with the medicine photographing device 104 to read the identification information, thereby contributing to the improvement of the inspection accuracy. In this regard, the example in which the first rotating roller 114 and the second rotating roller 116 have the dark color is described in this embodiment, the present invention is not limited thereto and one or both of the first rotating roller 114 and the second rotating roller 116 may have light color such as white color.
The medicine packaging apparatus 10 of this embodiment is configured so that the members constituting the medicine rolling and moving device 102 have a charging suppressing effect. Thus, even if the medicines are rolled and moved in the medicine rolling and moving device 102, it is possible to reduce the possibility that the medicines and/or the medicine rolling and moving device 102 itself take charge due to the static electricity. This makes it possible to suppress the adverse effect that the medicines adhere to the medicine rolling and moving device 102 or the like due to the static electricity. In this regard, the example in which the constitution members of the medicine rolling and moving device 102 have the charging suppressing effect with considering that the static electricity occurs along with the rolling and moving of the medicines is described in this embodiment, it is not necessary to configure so that the constitution members of the medicine rolling and moving device 102 have the charging suppressing effect in a case where it is possible to reduce the adverse effect of the static electricity with any other configuration, in a case where it is unnecessary to consider the effect of the static electricity or the like.
The medicine packaging apparatus 10 of this embodiment has the movable portion 122 movably supporting the second rotational axis 116a of the second rotating roller 116 constituting the medicine rolling and moving device 102 and it is possible to expand the clearance between the first rotating roller 114 and the second rotating roller 166 to discharge the medicines by actuating the opening-closing mechanism 140 to lift up the movable portion 122. Further, by releasing the external force applied to the movable portion 122, the movable portion 122 is lowered by its own weight and thus it is possible to return the first rotating roller 114 and the second rotating roller 116 to the state that the medicine can be arranged on the first rotating roller 114 and the second rotating roller 116. Thus, in the medicine packaging apparatus 10 of this embodiment, a mechanism or the like for returning the movable portion 122 to the original posture after the medicines are dispensed is unnecessary and thus it is possible to simplify the apparatus structure. In this regard, the example in which the movable portion 122 returns to the original posture by its own weight when the external force is released after the medicine are dispensed is described in this embodiment, the present invention is not limited thereto and may be configured so that the movable portion 122 returns to the original posture by using a biasing member such as a spring or the like, for example.
The medicine packaging apparatus 10 of this embodiment can fix the movable portion 122 by using the fixing force due to the magnet with keeping the state that the movable portion 122 is lowered. Thus, when only external force weaker than the fixing force provided by the magnet is applied to the movable portion 122, the medicine rolling and moving device 102 is not actuated and the medicines are not leaked. In this regard, the example in which the movable portion 122 is fixed by the magnetic force is described in this embodiment, the present invention is not limited thereto and may be configured to provide any other fixing device to fix the movable portion 122.
Further, in the medicine packaging apparatus 10, the tray 142 is provided on the lower side of the medicine photographing device 104. Thus, by rotating the medicine at the position where the medicine photographing device 104 is provided to read the identification information, even if the powder of the medicine generates due to the effect of the friction force, it is possible to receive the powder with the tray 142. This makes it possible to suppress the time and effort required for cleaning the vicinity of the medicine photographing device 104 to a minimum.
Although the configuration in which only one medicine is arranged on the first rotating roller 114 and the second rotating roller 116 of the medicine rolling and moving device 102 and the medicine is rotated to read the identification information is described in this embodiment, the present invention is not limited thereto. Specifically, it may be possible to take a configuration in which a process (an integrated process) for rolling and moving the plurality of medicines on the first rotating roller 114 and the second rotating roller 116 at one time and photographing the plurality of medicines with the medicine photographing device 104 is performed to obtain the identification information on the plurality of medicines based on the image data obtained by the integrated process.
In this regard, in order to enable the integrated process, it is preferable that the medicines are not overlapped with each other on the first rotating roller 114 and the second rotating roller 166 and the medicines are supplied to the medicine rolling and moving device 102 in an area that the medicines can be aligned in the axial line direction of these rollers 114, 116. Based on such knowledgement, when a length of a portion which is the longest in the medicine is defined as a medicine length x and a length of a border line between the first rotating roller 114 and the second rotating roller 116 is defined as a border length X, a condition that a sum of the medicine lengths x of the plurality of medicines which are targets of the integrated process is equal to or less than the border length X is set as an execution condition for the integrated process. By performing the integrated document under such an execution condition, the plurality of medicines can rotate in the medicine rolling and moving device 102 without overlapping with each other. This makes it possible to obtain the identification information on the plurality of medicines from the image obtained by the medicine photographing device 104 and thus it is possible to make the operation required for the inspection even more efficient.
Further, as described above, the reading control part 230 may be any part as long as it can perform the action for reading the identification information attached to the medicine. Specifically, as shown in
Further, as shown in
Although the reading control part 230 may be configured to include one of the above-described configurations shown in
Although the example in which the portion including the printing unit 152 (the pre-packaging information writing portion) and the packaging unit 154 is described as the packaging portion 150 in this embodiment, the present invention is not limited thereto and the packaging portion 150 may be configured to further include other configurations as shown in
The blowing portion 300 is used for blowing air into the packaging paper on the upper stream side of the carrying path (illustrated by an arrowed line T in
Although the position from which the gas stream is blown by the blowing nozzle 304 may be any appropriate position, it is preferable that the position is set as follows, for example. Namely, it is preferable that the blowing nozzle 304 is configured so that the blowing nozzle 304 is positioned on the upper stream side of the carrying direction of the packaging paper than the packaging unit 154 and the gas stream is blown toward the downstream side of the carrying direction of the packaging paper than the hopper 166. Alternatively, as another concrete example, it is preferable that the blowing nozzle 304 is configured so that the position of the gas stream to be introduced into the packaging paper by the blowing nozzle 304 is located on the upper stream side of the carrying direction of the packaging paper than the packaging unit 154 and the gas stream is blown toward the downstream side of the carrying direction of the packaging paper than the width expanding portion 167.
Although an opening provided in the blowing nozzle 304 for blowing the gas stream may be arranged at any position, it is preferable that the opening is arranged so as to be located inside the two-folded packaging paper. Namely, it is preferable that the opening of the blowing nozzle 304 for blowing the gas stream is arranged in an area sandwiched by the packaging paper.
The introduction detecting portion 310 is used for detecting the introduction of the medicines from the hopper 166 into the packaging paper on the upper stream side of the carrying direction of the packaging paper than the packaging unit 154. The introduction detecting portion 310 includes a light emitting portion 312 which can emit detection light and a light receiving portion 314 which can receive the detection light. The introduction detecting portion 310 can detect the passing of the medicine on a condition that receiving of the detection light from the light emitting portion 312 at the light receiving portion 314 is stopped or a received amount of the detection light at the light receiving portion 314 decreases during the receiving of the detection light. The light receiving portion 314 is provided on the upper stream side of the carrying direction of the packaging paper than the light emitting portion 312. In this embodiment, the light receiving portion 314 is arranged on the side of the width expanding portion 167. Further, the light emitting portion 312 is arranged at a position facing the light receiving portion 314. In this embodiment, the light emitting portion 312 is provided at the blowing nozzle 304 of the blowing portion 300. Here, the widths of the both ends of the two-folded packaging paper in the width direction thereof are expanded by the width expanding portion 167 in a zone from the width expanding portion 167 to the heater roller 167 and a clearance between the both ends of the packaging paper in the width direction thereof narrows as it approaches the heater roller 164. As shown in an arrowed line B in
A lower end portion of the hopper 166 is positioned on the inner side of the packaging paper whose width is expanded by the width expanding portion 167. Further, the detecting range of the introduction detecting portion 310 is set so as to detect the introduction of the medicines in an area lower than the lower end portion of the hopper 166.
The post-packaging information writing portion 320 is used for writing the information onto the packaging paper in which the medicines have been packaged on the downstream side of the carrying direction of the packaging paper than the packaging unit 154. Whereas the printing unit 152 (the pre-packaging information writing portion) is provided for writing the information onto the packaging paper before the medicines are packaged on the upper stream side than the packaging unit 154, the post-packaging information writing portion 320 is different from the printing unit 152 in a point that the post-packaging information writing portion 320 is provided for writing the information onto the packaging paper after the medicines have been packaged.
As shown in
The writing mechanism 324 is arranged on another side, which is opposite to the rear side contacting portion 322, of the carrying path T of the packaging paper carried with the posture that the plane stands as the boarder. The writing mechanism 324 has a holder 331, an oscillating portion 332 and a front side contacting portion 334. The holder 331 is used for holding a writing member 336 for writing the information onto the packaging paper. In this embodiment, a pen is used as the writing member 336. Thus, the holder 331 is configured to hold the pen by inserting the pen therein.
As indicated by an arrowed line S in
The front side contacting portion 334 is a member provided integrally with the holder 331. Thus, by actuating the oscillating portion 332, it is possible to oscillate the front side contacting portion 334 together with the holder 331. The front side contacting portion 334 is formed from an elastic material such as a metal and a resin having elasticity. The front side contacting portion 334 is provided so as to be in a state that the front side contacting portion 334 protrudes toward the side of the carrying path T (the side of the rear side contacting portion 322) more than the holder 331. The front side contacting portion 334 can be constituted of a leaf spring curved or bent into a J-like shape or a U-like shape, for example. Further, the front side contacting portion 334 is provided at a position facing the rear side contacting portion 332. Thus, when the holder 331 is oscillated toward the side of the carrying path T (the side of the rear side contacting portion 322), the front side contacting portion 334 contacts with the packaging paper prior to the pen arranged in the holder 331 and the packaging paper is put between the front side contacting portion 334 and the rear side contacting portion 322 and becomes in a fixed state. When the holder 331 in this state is further oscillated toward the side of the carrying path T, the front side contacting portion 334 is pressed and becomes in a deflected state and then the pen contacts with the packaging paper. This makes it possible to write the information constituted of the point-like or line-like marks onto the surface of the packaging paper.
The tip end of the writing member 336 (the pen) is held by the holder 331 in a state that a cap (not shown in the drawings) is attached to the tip end. When the holder 331 is oscillated in the direction for approaching to the rear side contacting portion 322, the tip end of the pen is removed from the cap and the tip end of the pen contacts with the packaging paper. On the other hand, when the holder 331 is oscillated in the direction for separating away from the side of the rear side contacting portion 322, the tip end of the pen held by the holder 331 is capped again.
As described above, the post-packaging information writing portion 320 is arranged in the packaging paper carrying portion 330 and the packaging paper is carried with the posture that the plane of the packaging paper stands in the packaging paper carrying portion 30. With this configuration, the medicines are positioned on the lower side in the packaging bag due to their own weights and an area K in which the medicines do not exist on the upper side in the packaging bag as shown in
Although the example in which the packaging paper carrying portion 330 allows the packaging paper to be carried with the posture that the plane of the packaging paper stands in the substantially vertical direction is described in this embodiment, the present invention is not limited thereto. Namely, the packaging paper carrying portion 330 may be configured to allow the packaging paper to be carried with a posture that the plane of the packaging paper stands with a certain level inclination.
The packaging paper carrying portion 330 is configured so that the packaging paper is carried in the substantially vertical direction as shown in
In a case of taking the above-described configuration of the packaging portion 150, it is possible to perform a temperature rising suppressing control and a post-packaging information writing control described later with the control part 200. Hereinafter, the temperature rising suppressing control and the post-packaging information writing control will be described in detail.
<<Regarding the Temperature Rising Suppressing Control>>
The above-described temperature rising suppressing control is a control performed for preventing a temperature in the packaging paper in a medicine introducing waiting state on the upper stream side of the carrying direction of the packaging paper than the sealing portion from being too high at the time of waiting the introduction of the medicines from the medicine introducing portion into the packaging paper. The temperature rising suppressing control actuates the blowing device 302 under a condition that the sealing action (the packaging action) for the packaging paper in the packaging unit 154 is stopped and performs an action control for feeding the packaging paper to the side of the packaging unit 154 by a predetermined amount under a condition that the temperature in the packaging paper exceeds a predetermined temperature condition. Hereinafter, the temperature rising suppressing control will be described in detail according to a flowchart shown in
(Step 1-1)
In the temperature rising suppressing control, at first, at a step 1-1, it is confirmed by the control part 200 whether or not the packaging operation is stopped. In a case where the packaging action is stopped (step 1-1=YES), the control flow is shifted to a step 1-2. In a case where the packaging operation is continuing (step 1-1=NO), the sequential control flow finishes.
(Step 1-2)
At the step 1-2, the blowing device 302 is turned on by the control part 200. This makes it possible to introduce low-temperature air (in this embodiment, external air) into the packaging paper waiting for the sealing on the upper stream side of the packaging unit 154. After that, the control flow shifts to a step 1-3.
(Step 1-3)
At the step 1-3, it is confirmed whether or not the temperature in the packaging paper waiting for the sealing on the upper stream side of the packaging unit 154 is in a state that the temperature exceeds the predetermined temperature condition. The temperature in the packaging paper can be derived by an appropriate method such as a method of directly measuring the temperature with a temperature sensor not shown in the drawings and a method of indirectly deriving the temperature from a lapsed time until the packaging action is stopped, a temperature outside the packaging paper or an arrangement atmosphere temperature of the medicine packaging apparatus 10. In a case where it is confirmed that the temperature in the packaging paper is in the state that the temperature exceeds the predetermined temperature condition (step 1-3=YES), the control flow shifts to a step 1-4. In a case where the temperature in the packaging paper is in a state that the temperature is equal to or lower than the predetermined temperature condition (step 1-3=NO), the control flow returns to the step 1-1.
(Step 1-4)
At the step 1-4, the packaging paper is fed to the side of the packaging unit 154 by the predetermined amount to perform an action (an enforced sealing action) for sealing the packaging paper. With this action, coming and exiting of air (a gas stream) in the packaging paper occurs and thermal energy is consumed by heat quantity required for the sealing in the packaging unit 154, thereby suppressing the temperature in the packaging paper from being too high.
<<Regarding the Post-Packaging Information Writing Control>>
The above-described post-packaging information writing control is a control for writing the information onto the packaging paper after the medicines have been packaged in the packaging paper with the post-packaging information writing portion 320. Hereinafter, the post-packaging writing control will be described in detail according to a flowchart shown in
(Step 2-1)
At a step 2-1, it is confirmed whether or not the packaging for the medicines has been finished in the packaging unit 154 and the packaging bag reaching the post-packaging information writing portion 320 is one onto which any information should be written. For example, it is confirmed whether or not the packaging bag in which the medicines which are determined to have problems as a result of the above-described inspection are packaged is one onto which any information such as a mark for distinguishing one from others having no problems should be written. Here, in a case of determining that the packaging bag is the one onto which the information should be written (step 2-1=YES), the control flow shifts to a step 2-2. In a case of determining that the packaging bag is not the one onto which the information should be written (step 2-1=NO), the sequent control flow finishes.
(Step 2-2)
In the case of determining that the packaging bag is the one onto which the information should be written at the above-described step 2-1, the control part 200 performs a control for stopping the carrying of the packaging paper at the step 2-2. At this time, a carrying stop position of the packaging paper is set so that the packaging bag onto which the information should be written reaches between the rear side contacting portion 322 and the front side contacting portion 334 constituting the post-packaging information writing portion 320.
(Step 2-3)
At a step 2-3, the control part 200 actuates the oscillating portion 332. With this control, the front side contacting portion 334 first contacts with the packaging paper and the packaging paper becomes in a state that the packaging paper is put and fixed between the front side contacting portion 334 and the rear side contacting portion 322. After that, when the holder 331 is further oscillated toward the side of the carrying path T, the pen held by the holder 331 contacts with the packaging paper. This makes it possible to write the information constituted of the point-like mark or mark on the line onto the surface of the packaging paper. With this control, the sequent control flow finishes.
As described above, the packaging portion 150 includes the blowing portion 300 and is configured to blow the air into the packaging paper on the upper stream side than the packaging unit 154. Further, if the blowing of the air by the blowing portion 300 is performed under the condition that the introduction of the medicines into the packaging paper from the hopper 166 is waiting, it is possible to reliably prevent the temperature in the packaging paper form rising due to the effect of temperature rising in the packaging unit 154 or the like. Thus, by providing the blowing portion 300, it is possible to suppress the medicines supplied into the packaging paper in order to prepare for the packaging from being adversely affected by heat or the like. In this regard, the example in which the blowing portion 300 is provided is described in the above-described example, the present invention is not limited thereto and may be configured not to include the blowing portion 300.
Further, as described above, by feeding the packaging paper to the side of the packaging unit 154 by the predetermined amount under the condition that the temperature in the packaging paper becomes in the state that the temperature exceeds the predetermined temperature condition on the upper stream side of the carrying direction of the packaging paper than the packaging unit 154 to perform the enforced sealing action, it is possible to obtain the suppressing effect of the temperature rising and thus it is possible to suppress the medicines from being adversely affected by the heat. In this regard, the present invention is not necessarily configured to perform the enforced sealing action.
As described above, by providing the one whose detection range is set in the packaging paper as the introduction detecting portion 310 for detecting the introduction of the medicines into the packaging paper, it is possible to precisely detect whether or not the medicines supplied from the roll 156 are introduced into the packaging paper through the hopper 166. Further, by arranging the light receiving portion 314 of the introduction detecting portion 310 on the side of the width expanding portion 167 and arranging the light emitting portion 312 at the position facing the light receiving portion 314, it is possible to detect the introduction of the medicines into the packaging paper without missing the introduction. Further, since the light emitting portion 312 is provided at the blowing portion 300, it is possible to prevent the light emitting portion 312 from getting dirty by the powder caused from the medicine or the like, thereby preventing the detection accuracy from deteriorating. In this regard, the introduction detecting portion 310 is not an essential configuration in the present invention and it is possible to appropriately omit the introduction detecting portion 310. Further, the introduction detecting portion 310 is not necessarily configured to be the one as described above, it is possible to replace the introduction detecting portion 310 with other sensors or the like.
In a case of configuring the packaging portion 150 as described above, the packaging portion 150 takes a distinguishing configuration in which the information can be written onto the packaging paper on not only the upper stream side of the carrying direction of the packaging paper than the packaging unit 154 but also the downstream side than the packaging unit 154. Specifically, it is possible to not only write the information onto the packaging paper before the medicines are packaged with the printing unit 152 provided on the upper stream side than the packaging unit 154 but also write the information onto the packaging paper with the post-packaging information writing portion 320 provided on the downstream side than the packaging unit 154.
Further, as one operational example in a case of configuring the packaging paper 150 as described above, it is possible to take a configuration in which characters are mainly written onto the packaging paper before the packaging and symbols are mainly written onto the packaging paper after the packaging. Examples of the information written with the characters include contents of the prescription data, a medicine name, a dosage time and a patient name. Examples of the information written with the symbols include an inspection result of the medicine kind, a result of the detection in the introduction detecting portion 310 and the like.
Further, at the position where the packaging paper is carried in the vertical direction after the medicines have been packaged (in this embodiment, the position where the packaging bag is carried in the state that the packaging bag stands in the vertical direction), the medicines are eccentrically located on the lower side in the packaging bag. Since the post-packaging information writing portion 320 is arranged at such a position, it is possible to write the information with the post-packaging information writing portion 320 with targeting the position on the upper side of the packaging bag where the medicines do not exist and the number of undulations is small with the post-packaging information writing portion 320.
Further, the above-described post-packaging information writing portion 320 can allow the packaging paper to be in the packaging paper fixed state that the packaging paper is put between the front side contacting portion 334 and the rear side contacting portion 322 to write the information with the pen or the like in a state that the packaging paper is stabilized in the vicinity of the post-packaging information writing portion 320. Further, in the above-described packaging portion 150, the post-packaging information writing portion 320 is provided at the position adjacent to the downstream side of the carrying direction of the packaging paper than the packaging unit 154. Thus, even if the packaging bag formed by packaging the medicines with the packaging paper has any length, it is possible to appropriately write the information.
In this regard, although the configuration in which the post-packaging information writing portion 320 is provided is described in the above-described example of the packaging portion 150, the present invention is not limited thereto and may be configured not to include the post-packaging information writing portion 320. Further, the configuration of the post-packaging information writing portion 320 is not limited to the above-described configuration. Specifically, it may be possible to take a configuration in which one or both of the front side contacting portion 334 and the rear side contacting portion 322 are not provided or a configuration in which the member held by the holder 331 is replaced with other tools such as a stamp instead of the pen. Further, the arrangement of the post-packaging information writing portion 320 can be appropriately modified. Further, when a packaging error occurs, it is possible not to write a message indicating that the packaging error occurs onto the packaging bag which is cause of the error but writing the message with other methods. Specifically, when one or more of the packaging errors occur in the sequent packaging process, it may be possible to write the message onto any one of the subsequent packaging bags. In this case, although the packaging bag onto which the message indicating that the packaging error occurs should be written may be any one of the packaging bags, it is preferable to write the message onto one which can be easily recognized by a user such as the last one of the packaging bags, for example. With this configuration, the user can understand that the packaging bag at which the packaging error occurs exists in the subsequent packaging paper by seeing the last one of the packaging bags, for example.
Further, although the above-described rolling and moving unit 110 is configured to include the contact type driving mechanism constituted of the driving force applying portion 120a and the like, the present invention is not limited thereto and may be configured to include a non-contact type driving mechanism. Specifically, as shown in
Although the representative embodiment of the present invention is described up to here, it is possible to perform various design changes within the technical sprit of the present invention described in the claims and these modifications are also contained in the present invention.
The present invention can be appropriately utilized in a general medicine packaging apparatus for packaging medicines.
