This application claims priority to Japanese Patent Application No. 2015-133719, the disclosure of which is incorporated herein by reference in its entirety.
The present invention relates to a medicine feeding apparatus configured to feed medicine, or to a medicine passing apparatus configured to allow medicine to pass therethrough.
There is a medicine feeding apparatus provided in a tablet packing machine disclosed, for example, in Patent Literature 1. This medicine feeding apparatus includes a medicine passage (medicine passing apparatus) configured to allow medicine to pass therethrough.
In such a medicine passage, if there is an undesired gap, medicine may leak from the medicine passage through the gap. Such leakage of medicine is not preferable because, for example, it makes it impossible to package the medicine as prescribed. Therefore, in the case where the medicine passage is composed of a plurality of components, the distances among the plurality of components need to be strictly adjusted so as not to allow formation of such an undesired gap. However, the work to adjust the distances among the plurality of components takes time and labor.

Next, the present invention will be described with reference to an embodiment of a medicine packaging apparatus including a medicine feeding apparatus and a medicine passing apparatus. A medicine packaging apparatus 1 of this embodiment is an apparatus configured to form a medicine package P by automatically packaging medicine M using a packaging sheet 3 and a cover sheet 4 that are packaging materials for packaging the medicine M.
As shown in
The packaging sheet holder 11 holds the packaging sheet 3 that is flat. The packaging sheet 3 is a resin sheet. As the packaging sheet 3 of this embodiment, a thermoplastic resin sheet is used, for example. The packaging sheet 3 has an elongated strip shape and is held by the packaging sheet holder 11 so as to be drawable while being wound into a rolled body 3a. The width dimension of the packaging sheet 3 is a dimension that allows one recess 31 to be formed therein. The flat packaging sheet 3 is not limited to those having an elongated strip shape. The configuration can be such that the flat packaging sheet 3 has a (short) quadrangular shape in planar view, and a plurality of packaging sheets 3 are stacked in the packaging sheet holder 11. Further, the packaging sheet 3 of this embodiment is transparent. Therefore, it is easy to visually recognize from the outside the medicine M contained in the recess 31 after being packaged. In this embodiment, the transparent packaging sheet 3 is used, but the packaging sheet 3 is not necessarily transparent. The packaging sheet 3, for example, may be semi-transparent or may be opaque.
Since the flat packaging sheet 3 can be used in this embodiment, the medicine packaging apparatus 1 can be configured so that the packaging sheet 3 wound into a roll is held by the packaging sheet holder 11, or a large number of packaging sheets 3 having a quadrangular shape in planar view are stacked and held by the packaging sheet holder 11. That is, the medicine packaging apparatus 1 can hold the packaging sheet(s) 3 in the packaging sheet holder 11, in an amount that allows a large number of medicine packages P to be formed at a time. Therefore, there is no need to set trays having housing recesses one by one by hand as in conventional techniques. The operator of the medicine packaging apparatus is thus relieved of the troublesome work. The word “flat” includes an embodiment in which projections and recesses or patterns are formed without hindering the formation of the recess 31 by the recess former 13, which will be described below.
The packaging sheet feeder 12 takes the packaging sheet 3 out of the packaging sheet holder 11 and feeds the packaging sheet 3 in the longitudinal direction. The packaging sheet 3 is fed while the tension is adjusted by a plurality of rollers 121 as shown in the figure. The packaging sheet 3 is drawn by a transport device (not shown) provided immediately upstream of the cutter 19, which will be described below. Therefore, the packaging sheet 3 is taken out of the packaging sheet holder 11. The feeding of the packaging sheet 3 is stopped when the recess 31 is formed in the packaging sheet 3 by a forming mold 133, which will be described below. Therefore, the feeding is intermittently carried out. Since the medicine M can be put into the packaging sheet 3 automatically fed by the packaging sheet feeder 12 after molding the packaging sheet 3, the medicine M can be packaged easily. As a device for taking out the packaging sheet 3, a device, for example, configured to sandwich and draw the packaging sheet 3 can be employed and various devices such as rollers, arms, and rubber plates can be employed. In particular, in the case of using the packaging sheets 3 having a quadrangular shape in planar view, the packaging sheet feeder 12 is configured so as to be capable of taking the packaging sheets 3 out of the packaging sheet holder 11 one by one.
The recess former 13 forms a plurality of the recesses 31 in the packaging sheet 3 fed by the packaging sheet feeder 12 at specific intervals in the longitudinal direction. The recess former 13 includes a hot plate 131, a receiving part 132, and the forming mold 133.
The hot plate 131 and the receiving part 132 are opposed to each other with the conveyed packaging sheet 3 being interposed therebetween, and their opposed surfaces are flat. The hot plate 131 is located below the packaging sheet 3, and the receiving part 132 is located thereabove. The hot plate 131 and the receiving part 132 may be inversely arranged with respect to the packaging sheet 3. A heater is incorporated in the hot plate 131. The receiving part 132 is made of resin and is made of rubber in this embodiment. The receiving part 132 may serve as another hot plate in which a heater is incorporated. The hot plate 131 and the receiving part 132 are configured to be capable of moving close to and away from the packaging sheet 3 by being driven by an electric motor. The driving source to drive the hot plate 131 and the receiving part 132 is not limited to the electric motor. The driving source of the hot plate 131 and the receiving part 132 may be any device that can cause the hot plate 131 and the receiving part 132 to move close to and away from the packaging sheet 3. The driving source of the hot plate 131 and the receiving part 132 may be, for example, an air cylinder or a hydraulic cylinder. The hot plate 131 and the receiving part 132 move close to the packaging sheet 3 so as to sandwich the packaging sheet 3, while the hot plate 131 is heated by energizing the heater, thereby softening the packaging sheet 3.
The hot plate 131 and the receiving part 132 are formed to have a dimension of two packages (equivalent to two recesses 31) in the longitudinal direction. Meanwhile, the packaging sheet 3 intermittently moves so that the recess 31 is formed for each package (equivalent to one recess 31) by the forming mold 133. With such intermittent movement, the packaging sheet 3 is fed to the forming mold 133 after being heated twice. Therefore, the first heating serves as so-called “preheating”, and the second heating serves as so-called “main heating”, thereby sufficiently softening the packaging sheet 3 for forming the recess 31. The hot plate 131 and the receiving part 132 are not necessarily formed to have the dimension of two packages (equivalent to two recesses 31) in the longitudinal direction. If the packaging sheet 3 is sufficiently softened by heating once, the hot plate 131 and the receiving part 132 may be formed to have a dimension of one package (equivalent to one recess 31) in the longitudinal direction. If the packaging sheet 3 is not sufficiently softened by heating twice, the hot plate 131 and the receiving part 132 may be formed to have a dimension of three packages (equivalent to three recesses 31) or more in the longitudinal direction.
The forming mold 133 is located on the downstream side of the hot plate 131 and the receiving part 132 in the sheet conveying direction. The forming mold 133 includes a female mold 133a located below the conveyed packaging sheet 3, and a male mold 133b and a holding plate 133c located thereabove. The female mold 133a and the male mold 133b are formed to have a shape corresponding to the recess 31 so as to be capable of forming the recess 31 having desired diameter and dimension. The recess 31 formed in this embodiment has a circular cross-sectional shape with a diameter dimension decreasing as it advances downward, as shown in the figure. A plurality of suction holes (not shown) are formed on the recessed molding surface of the female mold 133a.
The female mold 133a, the male mold 133b, and the holding plate 133c are configured to be capable of moving close to and away from the packaging sheet 3 by being driven by an electric motor. The driving source to drive the female mold 133a, the male mold 133b, and the holding plate 133c is not limited to the electric motor. The driving source of the female mold 133a, the male mold 133b, and the holding plate 133c may be any device that can cause the female mold 133a, the male mold 133b, and the holding mold 133c to move close to and away from the packaging sheet 3. The driving source of the female mold 133a, the male mold 133b, and the holding plate 133c may be, for example, an air cylinder or a hydraulic cylinder.
The male mold 133b and the holding plate 133c move close to the female mold 133a so as to sandwich the packaging sheet 3 softened by the hot plate 131. While the packaging sheet 3 is interposed between the female mold 133a and the holding plate 133c, air is suctioned through the plurality of suction holes, thereby forming the recess 31 recessed downward in the packaging sheet 3. In such a state, the male mold 133b is further fitted into the female mold 133a, thereby reliably forming the recess 31 having a desired shape. The male mold 133b is not necessarily provided. If the recess 31 having a desired shape can be formed by suctioning air through the plurality of suction holes of the female mold 133a, the male mold 133b may be omitted.
The forming mold 133 of this embodiment is provided as one set, so that one recess 31 is formed at a time (with one cycle of vertical movement of the female mold 133a and the male mold 133b), but a plurality of recesses 31 can be formed at a time by arranging plural sets of forming molds 133 in parallel along the longitudinal direction of the packaging sheet 3 or the width direction of the packaging sheet 3 (the front-back direction in
The medicine feeder body 14 temporarily stores the medicine M and feeds the medicine M to the medicine passage 15 according to the prescription data (for example, for each dose). The medicine feeder body 14 has a storage 141 configured to temporarily store the medicine M, and can selectively feed the medicine M from the storage 141 according to the control by the control unit (not shown). Examples of the storage 141 for tablets include a storage cassette and a distribution cell in which a plurality of recesses are arranged in the form of a matrix. Further, examples of the storage 141 for powder include a cell unit including recesses having a V-shaped vertical cross section and a disk-shaped powder dispensing apparatus configured to scrape the powder according to the prescription data. However, the medicine feeder body 14 is not limited to the aforementioned embodiments and can be implemented by various embodiments. The storage 141 can be constituted, for example, by a plurality of per-type storages configured to store the medicine M for each type or a plurality of per-dose storages configured to store the medicine M for each dose. In this case, the medicine feeder body 14 can store the medicine M for each type or for each dose in a state that is suitable for feeding the medicine M. In the case of storing the medicine M for each type using the per-type storages, refilling with the medicine M can be facilitated. Further, in the case of storing the medicine M for each dose using the per-dose storages, the medicine M can be fed to the medicine passage 15 as it is stored.
The medicine feeder body 14 of this embodiment can handle medicine in various dosage forms. For example, tablets, capsules, and powders can be mentioned. Further, this embodiment is configured to handle only solid medicine, but it is also possible to handle medicine in liquid or gel form depending on the circumstances.
The medicine passage 15 serving as the medicine passing apparatus allows medicine to pass therethrough and puts the medicine M into each recess 31 formed in the packaging sheet 3 by the recess former 13. The medicine passage 15 constitutes a medicine feeding apparatus 1X (shown by the dashed-double-dotted lines in
The cover sheet holder 16 holds the cover sheet 4 that is flat. As the cover sheet 4 of this embodiment, a resin sheet is used. The cover sheet 4 has a strip shape and is held by the cover sheet holder 16 so as to be drawable while being wound into a rolled body 4a. The cover sheet 4 has a width so as to be capable of covering the openings of the recesses 31 formed in the packaging sheet 3. The width of the cover sheet 4 of this embodiment is the same as the width of the packaging sheet 3. As the cover sheet 4, paper also can be used. The paper may be coated with resin.
The cover sheet feeder 17 feeds the cover sheet 4 configured to close the openings of the recesses 31 to the packaging sheet 3 in which the recesses 31 have been formed and the medicine M has been put into the respective recesses 31. The cover sheet feeder 17 feeds the cover sheet 4 onto the upper surface of the packaging sheet 3. In this embodiment, the cover sheet feeder 17 feeds the cover sheet 4 to the packaging sheet 3 from above. The cover sheet feeder 17 may feed the cover sheet 4 from a lateral side of the packaging sheet 3 or may feed the cover sheet 4 from below. The cover sheet feeder 17 takes the cover sheet 4 out of the cover sheet holder 16 and feeds the cover sheet 4 in the longitudinal direction. The cover sheet 4 is fed while the tension is adjusted by a plurality of rollers 171 as shown in the figure. The cover sheet 4 is drawn by a transport device (not shown) provided immediately upstream of the cutter 19, which will be described below. Therefore, the cover sheet 4 is taken out of the cover sheet holder 16. In this embodiment, the packaging sheet 3 and the cover sheet 4 are drawn by a common transport device. The feeding is stopped when the cover sheet 4 is bonded to the packaging sheet 3 by the cover sheet bonding unit 18, which will be described below. Therefore, the feeding is intermittently carried out. This intermittent feeding of the cover sheet 4 is synchronized with the feeding of the packaging sheet 3. As a device for taking out the cover sheet 4, a device, for example, configured to sandwich and draw the cover sheet 4 can be employed, and various devices such as rollers, arms, and rubber plates can be employed.
The cover sheet bonding unit 18 bonds the cover sheet 4 fed by the cover sheet feeder 17 to the packaging sheet 3 in the state where the openings of the recesses 31 are covered to be closed by the cover sheet 4. The cover sheet bonding unit 18 includes a hot plate 181 and a receiving part 182. The hot plate 181 and the receiving part 182 are opposed to each other while the conveyed cover sheet 4 and the portion of the packaging sheet 3 where the recesses 31 are not formed are interposed therebetween, and their opposed surfaces are flat. The hot plate 181 is located above the cover sheet 4, and the receiving part 182 is located therebelow. A heater is incorporated in the hot plate 181. The receiving part 182 is made of resin and is made of rubber in this embodiment. The receiving part 182 may serve as another hot plate in which a heater is incorporated. The hot plate 181 and the receiving part 182 are configured to be capable of moving close to and away from the cover sheet 4 and the packaging sheet 3 by being driven by an electric motor. The driving source to drive the hot plate 181 and the receiving part 182 is not limited to the electric motor. The driving source of the hot plate 181 and the receiving part 182 may be any device that can cause the hot plate 181 and the receiving part 182 to move close to and away from the cover sheet 4 and the packaging sheet 3. The driving source of the hot plate 181 and the receiving part 182 may be, for example, an air cylinder or a hydraulic cylinder. Though not shown, a recessed portion into which the recess 31 is fitted is formed in the receiving part 182, so as to prevent the receiving part 182 and the recesses 31 from interfering with each other. In this embodiment, a circular hole passes through the center of the receiving part 182 as the recessed portion, so that the receiving part 182 does not interfere with the recess 31 when the receiving part 182 moves upward. The hot plate 181 and the receiving part 182 sandwich the cover sheet 4 and the packaging sheet 3 while the hot plate 181 is heated, thereby bonding (heat sealing) the cover sheet 4 to the packaging sheet 3, so that the medicine packages P are formed. This bonding prevents the medicine M put into the recesses 31 from leaking from the recesses 31. In the case where paper is used as the cover sheet 4, the cover sheet bonding unit 18 can perform the bonding while an adhesive is interposed between the cover sheet 4 and the packaging sheet 3.
While the cover sheet 4 is bonded to the packaging sheet 3, the cutter 19 cuts the two sheets 3 and 4 together for each dose or multiple doses. The cutter 19 of this embodiment includes cutting blades 191 that are located above and below the packaging sheet 3 and are movable so that their blade tips overlap each other. The medicine packages P are thus cut into a separate unit that is easy for patients to take. Therefore, the medicine packages P in the unit of each dose or multiple doses can be obtained.
It is also possible to form perforations through the packaging sheet 3 and the cover sheet 4 by changing the shape of the cutting blades 191. Such formation of perforations enables patients to appropriately cut the medicine packages P according to the convenience of patients, and therefore the patient usability is improved when taking a medicine or storing the medicine packages P. Other than such perforations, it is also possible to form a fragile portion with reduced rigidity or reduced sheet thickness as compared to other portions, so as to help patients cut the medicine packages P.
The printer 20 prints information corresponding to the prescription data on the cover sheet 4. The printer 20 can perform printing as a series of steps and thus can facilitate forming the medicine packages P into a state ready to be delivered to patients. Examples of print contents include the patient name, the date and/or the day of the week for dosing, and the timing of dosing (such as after meals, before meals, and between meals). In this embodiment, the printing is performed on the cover sheet 4 before being bonded to the packaging sheet 3. Therefore, the printer 20 is located above the conveyance line of the packaging sheet 3. It is also possible to perform the printing on the cover sheet 4 after being bonded to the packaging sheet 3. As a printing method, a thermal transfer method using an ink ribbon can be mentioned, but various methods such as an ink jet method can be employed.
Next, the medicine passage 15 will be described. As shown in
The inlet 151 is arranged below the medicine feeder body 14 by being fixed to part of the structural material of the medicine packaging apparatus 1 (shown by the dashed-double-dotted line in
The outlet 152 is a part that is arranged below the inlet 151 and above the packaging sheet 3 in which the plurality of recesses 31 are formed and is configured to allow the medicine M fed by the medicine feeder body 14 to exit downward therethrough. The medicine passage 152a that passes through the outlet 152 in the vertical direction and is configured to allow the medicine M to fall down is formed in the outlet 152. The medicine passage 152a has a substantially square cross-sectional shape which is narrowed as it advances downward. The cross-sectional shape of the medicine passage 152a is not limited to the substantially square shape and may be an elliptical shape or a circular shape, for example. The cross-sectional shape of the medicine passage 152a is not necessarily narrowed as it advances downward, and may expand or stay constant as it advances downward.
The outlet 152 is detachably attached to a specific position in the upper part of the packaging sheet 3, independently of the communication part 153. Specifically, as shown in
A holding unit 1524 having a plate shape is formed at the lower end of the outlet 152. The holding unit 1524 can reliably guide the medicine M to the recess 31, without leakage of the medicine M falling down from the outlet 152 through the gap between the outlet 152 and the packaging sheet 3, by covering the recess 31 in the packaging sheet 3 located immediately below the outlet 152. At least the upstream end in the sheet conveying direction of the holding unit 1524 has an upwardly warped shape (in this embodiment, the same applies also to the downstream end in the sheet conveying direction). Therefore, when the packaging sheet 3 is located below the outlet 152 before starting the operation of the medicine packaging apparatus 1, the packaging sheet 3 is less likely to be caught by the outlet 152, so that the operation can be smoothly performed.
The communication part 153 is a part communicating the inlet 151 and the outlet 152 with each other. The medicine passage 153a that passes through the communication part 153 in the vertical direction and is configured to allow the medicine M to fall down is formed in the communication part 153. Therefore, the upper part of the medicine passage 153a is in communication with the medicine passages 151a of the inlet 151 and the lower part of the medicine passage 153a is in communication with the medicine passage 152a of the outlet 152. In the upper part, the medicine passage 153a has a rectangular cross-sectional shape that is elongated along the sheet conveying direction. The long side dimension of the rectangular shape of the medicine passage 153a decreases as it advances downward, and the cross-sectional shape in the lower part is a substantially square shape. The cross-sectional shape of the medicine passage 153a is not limited to the rectangular shape or the square shape and may be an elliptical shape or a circular shape, for example. The cross-sectional shape of the medicine passage 153a is not necessarily narrowed as it advances downward, and may expand or stay constant as it advances downward. The communication part 153 includes an upper part 1531, a lower part 1532, and a middle part 1533.
As shown in
Meanwhile, the lower part 1532 is loosely fitted to the outlet 152 from the inside so as to be connected by being inserted into an upper part 1521 of the outlet 152 in the perpendicular direction. Due to the loose fitting from the inside, the gap between the communication part 153 and the outlet 152 is open to the outside of the medicine passage 15 above the lower end of the communication part 153, as shown in
The middle part 1533 is a part configured to couple the upper part 1531 and the lower part 1532 integrally. In the medicine passage 15 of this embodiment, the outlet 152 is located forward of the inlet 151 (on the left in
As shown in
The projection 1535 projects outwardly from the lower part 1532 in the form of a flange. The projection 1535 abuts an upper end face 1521a of the outlet 152 (see
The opening and closing mechanism 154 includes the opening and closing plate 1542 configured to move in the front-rear direction. The opening and closing plate 1542 controls the input of the medicine M into the recess 31 formed in the packaging sheet 3 by crossing between the medicine passage 153a in the communication part 153 and the medicine passage 152a in the outlet 152, so as to open and close the space communicating the communication part 153 and the outlet 152 with each other.
According to the medicine packaging apparatus 1 of this embodiment configured as above, the feeding of the packaging sheet 3, the formation of the plurality of recesses 31, and the input of the medicine M can be automatically performed. Therefore, blister packaging can be easily performed.
In particular, the inlet 151 and the outlet 152 are provided in the medicine passage 15 as separate bodies from each other. Therefore, the adjustment work for the inlet 151 and the adjustment work for the outlet 152 can be individually performed. In the case where the inlet 151 and the outlet 152 are integrally provided, it is necessary to adjust the positions of the inlet 151 and the outlet 152 at the same time so that both the gap between the inlet 151 and the medicine feeder body 14 and the gap between the outlet 152 and the packaging sheet 3 fall within acceptable ranges. In contrast, according to the example of the aforementioned configuration, the positions of the inlet 151 and the outlet 152 can be individually adjusted. Accordingly, as compared with the case where the respective adjustment works need to be performed at the same time, the adjustment works can be facilitated.
Further, the communication part 153 is provided in the medicine passage 15 as a separate body from the inlet 151 and the outlet 152 and is connected to the inlet 151 and the outlet 152 so as to be positionally adjustable. Therefore, even if the relative position and posture of the inlet 151 and the outlet 152 change due to the adjustment works, the change can be absorbed. Such absorption of the change eliminates the need to strictly adjust the gap between the communication part 153 and the inlet 151 and the need to strictly adjust the gap between the communication part 153 and the outlet 152. Accordingly, the adjustment work for the communication part 153 can be omitted. In this way, the adjustment works for the inlet 151 and the outlet 152 can be facilitated, and the adjustment work for the communication part 153 can be omitted. Accordingly, the time and labor required for the works to adjust the distances among a plurality of components of the medicine passage 15 can be reduced in this embodiment. The communication part 153 may be connected to at least one of the inlet 151 and the outlet 152 so as to be positionally adjustable according to the change in the relative position and the posture of the inlet 151 and the outlet 152.
Finally, the configurations and operations of the aforementioned embodiments (including the modifications) will be summarized. The medicine feeding apparatus 1X according to the aforementioned embodiment includes: a medicine feeder body 14 configured to feed medicine M; and a medicine passage 15 configured to guide the medicine M fed by the medicine feeder body 14 to a packaging material 3 configured to package the medicine M, wherein the medicine passage 15 includes: an inlet 151 that is arranged below the medicine feeder body 14 and is configured to allow the medicine M fed by the medicine feeder body 14 to enter from above therethrough; an outlet 152 that is arranged below the inlet 151 and above the packaging material 3 and is configured to allow the medicine M fed by the medicine feeder body 14 to exit downward therethrough; and a communication part 153 that is configured to communicate the inlet 151 and the outlet 152 with each other, the inlet 151 and the outlet 152 are provided as separate bodies from each other, and the communication part 153 is provided as a separate body from the inlet 151 and the outlet 152 and is connected to the inlet 151 and the outlet 152 so as to be positionally adjustable.
According to the example of the aforementioned configuration, the medicine M is fed by the medicine feeder body 14. The medicine M fed by the medicine feeder body 14 is guided by the medicine passage 15 to the packaging material 3 configured to package the medicine M. In the medicine passage 15, the outlet 152 is arranged below the inlet 151, and the inlet 151 and the outlet 152 are communicated with each other by the communication part 153. The medicine M fed by the medicine feeder body 14 enters the inlet 151 from above, passes through the communication part 153, and exits through the outlet 152 downward. The inlet 151 and the outlet 152 are provided as separate bodies from each other. Therefore, the adjustment work for the inlet 151 and the adjustment work for the outlet 152 can be performed individually. The adjustment work for the inlet 151 is the work to adjust the gap between the inlet 151 and the medicine feeder body 14. The adjustment work for the outlet 152 is the work to adjust the gap between the outlet 152 and the packaging material 3. In the case where the inlet 151 and the outlet 152 are integrally provided, it is necessary to adjust the positions of the inlet 151 and the outlet 152 at the same time so that both the gap between the inlet 151 and the medicine feeder body 14 and the gap between the outlet 152 and the packaging sheet 3 fall within acceptable ranges. In contrast, according to the example of the aforementioned configuration, the positions of the inlet 151 and the outlet 152 can be individually adjusted. Accordingly, as compared with the case where the respective adjustment works need to be performed at the same time, the adjustment works can be facilitated. The communication part is provided as a separate body from the inlet 151 and the outlet 152 and is connected to the inlet 151 and the outlet 152 so as to be positionally adjustable. Therefore, even if the relative position and posture of the inlet 151 and the outlet 152 change due to the adjustment works, the change can be absorbed. Such absorption of the change eliminates the need to strictly adjust the gap between the communication part 153 and the inlet 151 and the need to strictly adjust the gap between the communication part 153 and the outlet 152. Accordingly, the adjustment work for the communication part 153 can be omitted. In this way, the adjustment works for the inlet 151 and the outlet 152 can be facilitated, and the adjustment work for the communication part 153 can be omitted. Accordingly, the time and labor required for the works to adjust the distances between a plurality of components of the medicine passage 15 can be reduced.
A medicine passing apparatus 15 according to an example of the configuration of this embodiment is the medicine passing apparatus 15 through which medicine M passes, the medicine passing apparatus 15 including: an inlet 151 that is configured to allow the medicine M fed by the medicine feeder body 14 to enter from above; an outlet 152 that is arranged below the inlet 151 and is configured to allow the medicine M to exit downward therethrough; and a communication part 153 that is configured to communicate the inlet 151 and the outlet 152 with each other, wherein the inlet 151 and the outlet 152 are provided as separate bodies from each other, and the communication part 153 is provided as a separate body from the inlet 151 and the outlet 152 and is connected to the inlet 151 and the outlet 152 so as to be positionally adjustable.
According to the example of the aforementioned configuration, the outlet 152 is arranged below the inlet 151, and the inlet 151 and the outlet 152 are communicated with each other by the communication part 153. The medicine M enters the inlet 151 from above, passes through the communication part 153, and exits through the outlet 152 downward. The inlet 151 and the outlet 152 are provided as separate bodies from each other. Therefore, the adjustment work for the inlet 151 and the adjustment work for the outlet 152 can be performed individually. Accordingly, as compared with the case where the respective adjustment works need to be performed at the same time, the adjustment works can be facilitated. The adjustment work for the inlet 151 is the work to adjust the gap between the inlet 151 and an object that provides the medicine M to the inlet 151. The adjustment work for the outlet 152 is the work to adjust the gap between the outlet 152 and an object to which the medicine M is provided from the outlet 152. The communication part 153 is provided as a separate body from the inlet 151 and the outlet 152 and is connected to the inlet 151 and the outlet 152 so as to be positionally adjustable. Therefore, even if the relative position and posture of the inlet 151 and the outlet 152 change due to the adjustment works, the change can be absorbed. Such absorption of the change eliminates the need to strictly adjust the gap between the communication part 153 and the inlet 151 and the need to strictly adjust the gap between the communication part 153 and the outlet 152. Accordingly, the adjustment work for the communication part 153 can be omitted. In this way, the adjustment works for the inlet 151 and the outlet 152 can be facilitated, and the adjustment work for the communication part 153 can be omitted. Accordingly, the time and labor required for the works to adjust the distances among a plurality of components can be reduced.
Further, the configuration can be such that the communication part 153 is vertically movable and is connected to the outlet 152 while being supported from below by the outlet 152 in an area within the vertically movable range.
According to the example of the aforementioned configuration, the communication part 153 is vertically movable and is connected to the outlet while being supported by the outlet from below by the outlet in an area within the vertically movable range. Therefore, the positional relationship among the inlet 151, the outlet 152, and the communication part 153 can be maintained by using the self-weight of the communication part 153 applied to the outlet 152. Accordingly, the configuration to maintain the positional relationship can be simplified.
Further, the configuration can be such that the communication part 153 is hung from the inlet 151.
According to the example of the aforementioned configuration, the communication part 153 is hung from the inlet 151. Therefore, even if the outlet 152 is detached, it is possible to prevent the communication part 153 from falling down.
Further, the configuration can be such that the communication part 153 is detachably attached to the outlet 152, and the outlet 152 is detachably attached to a specific position above the packaging material 3 independently of the communication part 153.
According to the example of the aforementioned configuration, the communication part 153 is detachably attached to the outlet 152. Further, the outlet 152 is detachably attached to a specific position above the packaging material 3 independently of the communication part 153. Therefore, the outlet 152 can be detached while leaving the communication part 153. Accordingly, the attachment and detachment work of the outlet 152 can be facilitated.
Further, the configuration can be such that the communication part 153 is loosely fitted to the inlet 151 from the outside so as to be connected and is loosely fitted to the outlet 152 from the inside so as to be connected.
According to the example of the aforementioned configuration, the communication part 153 is loosely fitted to the inlet 151 from the outside so as to be connected. Therefore, it is possible to prevent the medicine M from leaking through the gap between the communication part 153 and the inlet 151. Further, the communication part 153 is loosely fitted to the outlet 152 from the inside so as to be connected. Therefore, it is possible to prevent the medicine M from leaking through the gap between the communication part 153 and the outlet 152. Accordingly, it is possible to prevent the medicine M from leaking from the medicine passage 15.
Further, the configuration can be such that, in the connecting portion between the inlet 151 and the communication part 153, the medicine passage of the communication part 153 is located outwardly of the medicine passage of the inlet 151, and in the connecting portion between the communication part 153 and the outlet 152, the medicine passage of the outlet 152 is located outwardly of the medicine passage of the communication part 153.
According to the example of the aforementioned configuration, in the connecting portion between the inlet 151 and the communication part 153, the medicine passage of the communication part 153 is located outwardly of the medicine passage of the inlet 151. Therefore, it is possible to prevent the medicine M from being caught by the connecting portion. In the connecting portion between the communication part 153 and the outlet 152, the medicine passage of the outlet 152 is located outwardly of the medicine passage of the communication part 153. Therefore, it is possible to prevent the medicine M from being caught by the connecting portion. Accordingly, it is possible to prevent the medicine M from being caught within the medicine passage 15.
According to the example of the aforementioned configuration, this embodiment can reduce the time and labor required for the works to adjust the distances among a plurality of components of the medicine passage 15.
