The present invention relates to a coin processing apparatus and a coin depositing/dispensing machine equipped therewith and more particularly, to a coin processing apparatus that makes it sure to suppress the congestion of coins occurring in a coin storing space for temporarily storing a lot of coins which have been supplied from a con inlet, in which the congestion of coins is likely to be caused by a so-called Tawara state and/or a so-called Keirin phenomenon of the coins occurring on or over a conveying belt, and a coin depositing/dispensing machine equipped with the coin processing apparatus.
In this specification, the term “coin” has a wide meaning including not only coins as currency but also coin equivalents such as tokens and medals other than coins, in which the shape of “coin” is not limited to a circular shape and may be a polygonal or any other shape.
Conventionally, coin depositing/dispensing machines for automatically conducting the depositing and dispensing processes of coins have been known, as disclosed in, for example, Japanese Unexamined Patent Publication No. 2015-097001 issued on May 21, 2015. Coin depositing/dispensing machines of this type are configured as follows:
Coins thrown into a coin inlet are separated from each other by a coin separating and delivering section, and the denomination of the coins is discriminated by a coin discriminating section. Then, the coins thus discriminated are conveyed individually and distributed into their respective denominations to be sent to a coin storing section by a coin conveying section. Furthermore, designated denominations and designated numbers of the coins are selected and taken out of those stored in the coin storing section according to a predetermined dispensing signal (e.g., a dispensing signal for change) and then, dispensed into a coin outlet by a coin dispensing section. A depositing belt is disposed right below the coin inlet and an opening is formed over one end of the belt. A reversing roller is provided to be opposite to the depositing belt in such a way as to close the opening. The reversing roller is configured to be rotatable in the opposite direction to the conveying direction of the belt. Between the roller and the belt, a gap that allows one coin having a largest thickness of all the coins to be thrown to pass through is formed.
Because of the configuration as described above, coins thrown into the coin inlet are conveyed toward the gap by the depositing belt, and the passage of the coins that are overlapped or stacked on the belt in such a way as to have a larger height or thickness than that of the gap is restricted by the reversing roller. As a result, the coins can be transferred into the inside of the coin depositing/dispensing machine every several coins.
With the aforementioned prior-art coin depositing/dispensing machine, when a lot of coins are thrown into the coin inlet collectively, there is a possibility that a plurality of coins are closely aligned in their standing state on the depositing belt in the widthwise direction of the said belt so as to extend across the whole width of the said belt, forming a shape like a single cylinder. Such the state of the coins on the belt may be termed “Tawara state” below because it resembles in shape a Japanese ricebag “Tawara”. The coins that have been turned into the Tawara state in this way are interfered with each other and as a result, they cannot topple down on the belt, in other words, they cannot be turned into their lying state.
Moreover, even if the coins existing in the Tawara state are contacted with the rotating reversing roller, they simply continue to rotate around their centers on the belt while keeping their standing state and they are never turned into their lying state. Such the phenomenon of the coins that continues to rotate around their centers in their standing state on the belt may be termed “Keirin phenomenon” below because it resembles in shape a plurality of bicycles aligned in the famous Japanese bicycle race termed “Keirin”.
Once the aforementioned Keirin phenomenon occurs in the coins existing in the aforementioned Tawara state, even if the depositing belt is moved in the conveying direction or the opposite direction thereto (in other words, forward and backward) over and over again to eliminate the Keirin phenomenon, the respective coins are simply rotated around their centers in their standing state on the belt or moved forward and backward along with the movement of the belt while keeping the Tawara state and as a result, they are unable to be turned into their lying state on the belt. Accordingly, there arises a problem that a malfunction is likely to occur in the coin depositing process, such as a long time transfer that it takes a very long time to transfer a lot of coins to the inside of the coin depositing/dispensing machine. Such the malfunction leads to problems such as the operation efficiency degradation of the said machine.
To suppress the occurrence of the aforementioned Keirin phenomenon, a first prior art disclosed in Japanese Patent No. 3017885 issued on Dec. 24, 1999 is known.
This first prior art is a coin processing apparatus comprising a coin receiving chamber that receives collectively a lot of coins of several kinds thrown through a coin inlet; a conveying belt that forms the bottom of the coin receiving chamber and that is moved to convey out the coins that have been received in the said chamber through a coin delivering port of the chamber; a restricting means that is provided near the coin delivering port and that restricts the transmission of the coins in such a way that the coins are transmitted one by one in alignment; and a coin scooping-up means that is provided at the wall of the coin receiving chamber which is formed to extend in the direction perpendicular to the restricted transmission direction of the coins and that scoops up selectively the coins which have been received in the said chamber using the rotation action of the coin scooping-up means itself around an axis extending along the conveying direction of the belt.
Moreover, a second prior art for suppressing the occurrence of the aforementioned Keirin phenomenon is disclosed in Japanese Patent No. 4498776 issued on Apr. 23, 2010.
The second prior art is a coin depositing/dispensing machine for discriminating the denomination of deposited coins to receive the coins thus discriminated in the said machine and dispensing the coins thus received selectively. This apparatus comprises a coin inlet having an upward opening through which coins are thrown; a depositing belt that is provided at the bottom of the coin inlet, that is rotatively driven, and that conveys coins placed on an upper surface of the belt in the conveying direction for depositing coins; a reversing path that is provided on at least one side of the belt at the coin inlet, that extends in the conveying direction upward, that has s width equal to or greater than the largest coin thickness and is inclined downward, and that has a flat bottom surface with respect to the widthwise direction of the upper surface of the belt; and a guiding section that guides the coins which are guided by the reversing path toward the belt.
With the aforementioned coin processing apparatus as the first prior art, there is provided with a structure that the coins existing in the Tawara state in the coin receiving chamber are scooped up by a rubber roller with protrusions on its surface as the coin scooping-up means, thereby detaching a coin positioned at one end of the coin group in the Tawara state from the remainder. However, in the case where additional coins are overlapped or stacked on the coin group which is kept in the Tawara state, the scooping-up action of the roller to the coins is inhibited by the additional coins that are placed in an upper level than that of the coin to be scooped-up. Thus, there is a problem that the Tawara state of the coin group cannot be eliminated in the aforementioned case.
Moreover, with the aforementioned coin depositing/dispensing machine as the second prior art, there is provided with a structure that the coins positioned at the two ends of the coin group that exists in the Tawara state, which are standing upright on the inclined surface of the reversing path, rotate in the conveying direction upstream due to their own weight to topple down on the upper surface of the depositing belt on the upstream side of the conveying direction. However, in the case where additional coins are placed on the belt on the upstream side of the conveying direction with respect to the coin group existing in the Tawara state, the rotation action of the coins toward the upstream side of the conveying direction along the reversing path is inhibited by the additional coins placed on the upstream side. As a result, similar to the aforementioned coin processing apparatus as the first prior art, there is a problem that the Tawara state of the coin group cannot be eliminated in the aforementioned case as well.
The present invention was created to solve the aforementioned problems of the first and second prior-art apparatuses.
An object of the present invention is to provide a coin processing apparatus that eliminates quickly and surely a congestion of coins caused by a group of coins that have induced a Tawara state and/or a Keirin phenomenon on a conveying surface and a coin depositing/dispensing machine using the coin processing apparatus.
Another object of the present invention is to provide a coin processing apparatus that eliminates quickly and surely a congestion of coins even in the case where additional coins are overlapped or stacked on a group of coins that have induced a Tawara state and/or a Keirin phenomenon on a conveying surface and in the case where additional coins are placed on an upstream side of the conveying surface with respect to a group of coins that have induced a Tawara state and/or a Keirin phenomenon on the conveying surface
The above objects together with others not specifically mentioned will become clear to those skilled in the art from the following description.
According to a first aspect of the present invention, a coin processing apparatus is provided, which comprises:
(a) a coin conveying section for conveying coins, which are put therein through a coin inlet, in a desired attitude after separating the coins from each other; and
(b) a coin congestion suppressing section for suppressing a congestion of the coins that is generated during conveyance by the coin conveying section;
wherein the coin conveying section comprises;
a conveying belt for conveying coins that are put in the coin conveying section through the coin inlet in a predetermined conveying direction by placing the coins on a conveying surface of the belt, wherein a coin pusher is formed on the conveying surface in such a way as to be engageable with coins that are placed on the conveying surface in their lying state or their approximately lying state, thereby pushing the coins in the conveying direction by the coin pusher;
a driving means for moving the belt in the conveying direction; and
a reversing roller disposed at a predetermined position on the conveying surface so as to be opposite to the conveying surface to thereby form an introducing port between the reversing roller and the conveying surface; wherein the introducing port serves to allow coins that are placed on the conveying surface in a desired state to selectively pass through the port, and the reversing roller is rotated to move coins that are placed on the conveying surface toward an opposite side to the introducing port when the coins are contacted with the reversing roller;
and wherein the coin congestion suppressing section comprises one or more coin moving members for moving coins placed on the conveying surface toward the opposite side to the introducing port by engaging the coins with the one or more coin moving members, the one or more coin moving members being disposed on at least one side of the belt; and
if coins that are placed on the conveying surface in their standing state or their approximately standing state are engaged with the one or more coin moving members, the coins are moved by the one or more coin moving members toward the opposite side to the introducing port so as to topple down toward the conveying surface during movement.
With the coin processing apparatus according to the first aspect of the present invention, as explained above, the coin congestion suppressing section is provided in addition to the coin conveying section. The coin congestion suppressing section comprises the one or more coin moving members for moving coins placed on the conveying surface toward the opposite side to the introducing port, and the one or more coin moving members is/are disposed on at least one side of the belt. If coins that are placed on the conveying surface in their standing state or their approximately standing state are engaged with the one or more coin moving members, the coins are moved by the one or more coin moving members toward the opposite side to the introducing port so as to topple down toward the conveying surface during movement.
For this reason, if a group of coins is gathered on the conveying surface of the conveying belt to thereby induce a Tawara state and/or a Keirin phenomenon, there is an increase in the possibility that the coin(s) located at least one end of the group, which is/are opposed to the one or more coin moving members, is/are contacted and engaged with the one or more coin moving members. If so, the coin(s) opposed to the one or more coin moving members is/are moved on the conveying surface toward the opposite side to the introducing port while keeping its/their standing or approximately standing state and then, the said coin(s) is/are likely to be detached from the remainder of the group. In this state, the coin(s) is/are unstable and thus, the coin(s) is/are likely to topple down naturally toward the conveying surface during the movement thereof. Once such the action occurs, this action will be repeated naturally and therefore, the total number of the coins remaining in the group that have occurred the Tawara state and/or the Keirin phenomenon decreases gradually. As a result, the coins remaining in the said group will become more likely to sway laterally (i.e., in the direction perpendicular to the conveying direction). Finally, the Tawara state or the Keirin phenomenon of the group of coins disappears due to natural repetition of the aforementioned action.
Accordingly, even if a congestion of coins is caused by a group of coins that have induced a Tawara state and/or a Keirin phenomenon on the conveying surface of the conveying belt, the Tawara state and/or the Keirin phenomenon can be eliminated in a short time. This means that the congestion of coins caused by a group of coins that have induced a Tawara state and/or a Keirin phenomenon can be eliminated quickly and surely by the coin processing apparatus according to the first aspect of the present invention.
Moreover, since the coin pusher is formed on the conveying surface in such a way as to be engageable with coins that are placed on the conveying surface in their lying or approximately lying state, coins that are placed on the conveying surface in their lying or approximately lying state are likely to be engaged with the coin pusher and as a result, the coins can be surely pushed toward the introducing port along with the movement of the conveying surface. This is applicable to any case regardless of the presence or absence of the group of coins that have induced a Tawara state and/or a Keirin phenomenon in the vicinity of the reversing roller. Furthermore, aforementioned mechanism or operation principle that the Tawara state and/or the Keirin phenomenon is eliminated by the one or more coin moving members is effective even (i) in the case where additional coins are overlapped or stacked on a group of coins that have induced a Tawara state and/or a Keirin phenomenon on the conveying surface and (ii) in the case where additional coins are placed on an upstream side of the conveying surface with respect to a group of coins that have induced a Tawara state or a Keirin phenomenon on the conveying surface.
Accordingly, a congestion of coins can be eliminated quickly and surely even in the aforementioned cases (i) and (ii).
In a preferred embodiment of the coin processing apparatus according to the first aspect of the present invention, there is provided with one or more coin passage preventing members (e.g., an upper or lower brush) disposed adjacent to the one or more coin moving members at a higher or lower position or positions than the one or more coin moving members, wherein a gap or gaps is/are formed between the one or more coin passage preventing members and the one or more coin moving members;

wherein the coin receiving chamber comprises inner side walls that are respectively formed on two sides of the belt so as to extend in the conveying direction and that are curved so as to join to each other at their rear ends; and
when coins are moved in their standing or approximately standing state on the conveying surface toward the opposite side to the introducing port by the one or more coin moving members while being in contact with at least one of the inner walls, the coins will topple down naturally toward the conveying surface during movement thereof toward the rear ends of the inner side walls.

Moreover, a congestion of coins can be eliminated quickly and surely even in the case where additional coins are overlapped or stacked on a group of coins that have induced a Tawara state and/or a Keirin phenomenon on a conveying surface and in the case where additional coins are placed on an upstream side of the conveying surface with respect to a group of coins that have induced a Tawara state and/or a Keirin phenomenon on the conveying surface.
Accordingly, the operation efficiency of the coin depositing/dispensing process can be raised and at the same time, the convenience for users can be improved and the burden of persons in charge of coin depositing/dispensing can be reduced compared with the prior arts.
In order that the present invention may be readily carried into effect, it will now be described in detail with reference to the accompanying drawings.
Preferred embodiments of the present invention will be described in detail below while referring to the drawings attached.
A coin depositing/dispensing machine 1 according to an embodiment of the present invention is shown in
The overall schematic structure of the coin depositing/dispensing machine 1 according to the embodiment of the present invention is shown in
As shown in
A coin inlet 12 with an approximately circular shape through which a coin C is thrown is formed upward on (the horizontal surface of) the upper cover 6. Here, to make it possible for a user to throw a lot of coins C (e.g., 200 coins) simultaneously, a coin inlet cover 7 is attached to the coin inlet 12. However, the coin inlet cover 7 may be omitted. This is because a lot of coins C can be temporarily stored even if the cover 7 is omitted, in the case where, for example, a coin storing space with a sufficiently large size is formed right below the inlet 12. Here, as shown in
As shown in
The coin introducing section 10a is a section for separating a lot of coins C that have been put through the coin inlet 12 from each other and introducing the coins C thus separated into the inside of the coin depositing/dispensing machine 1 in a desired attitude. The detail of the structure and function of the coin introducing section 10a (the coin processing apparatus 10) will be explained later.
The coin separating and delivering section 20 is a section for separating the coins C conveyed from the coin introducing section 10a (the coin processing apparatus 10) individually and adjusting the attitude of the individual coins C thus separated to a desired one (here, a lying state, in other words, a tumbled state) to deliver the said coins C to the coin discriminating section 30, as shown in
The structure and function of the coin separating and delivering section 20 are not limited to those described here. Any other device or mechanism may be used as the coin separating and delivering section 20 if it has a function of separating the coins C conveyed from the coin introducing section 10a (the coin processing apparatus 10) individually and adjusting the attitude of the individual coins C thus separated to a desired one to deliver the said coins C to the coin discriminating section 30.
The coin discriminating section 30 is a section for discriminating the denomination of the coins C conveyed from the coin separating and delivering section 20 and generating a predetermined denomination signal based on the discrimination result to send the signal thus generated to the coin distributing section 50. Here, the coin discriminating section comprises a rotatable pushing member 32 and a magnetic sensor 34 and moves sequentially the coins C that are placed on the receiver 28 toward the coin distributing section 50 by the rotation of the pushing member 32, in which the discrimination of the denomination of the coins C is carried out during the moving process thereof. The denomination signal generated by the magnetic sensor 34 is sent to the coin distributing section 50 using a predetermined manner.
The structure and function of the coin discriminating section 30 are not limited to those described here. Any other device or mechanism may be used as the coin discriminating section 30 if it has a function of discriminating the denomination of the coins C conveyed from the coin separating and delivering section 20 and generating a predetermined denomination signal based on the discrimination result to send the signal thus generated to the coin distributing section 50.
The coin distributing section 50 is a section for distributing the coins C conveyed from the coin discriminating section 30 into their respective denominations to send the coins C thus discriminated to the coin storing section 60. Here, the coin distributing section 50 comprises a chain 54 stretched between a pair of sprockets 56, pusher pins 52 fixed at their predetermined positions on the chain 54, and a slide plate 58 provided under the chain 54 so as to have distributing gates 59 for the respective denominations. The pusher pins 52 fixed on the chain 54 that is moved at a predetermined velocity are engaged with the respective coins C conveyed from the coin discriminating section 30, thereby pushing the coins C sequentially along the longitudinal direction of the slide plate 58. During such the moving process of the coins C, corresponding ones of the distributing gates 59 are opened in response to the denomination signal sent from the coin discriminating section 30. For this reason, each of the coins C falls freely through a corresponding one of the gates 59 to the denomination thus discriminated to be sent to the coin storing section 60 through their different paths. The distribution of the coins C is carried out in this way.
The structure and function of the coin distributing section 50 are not limited to those described here. Any other device or mechanism may be used as the coin distributing section 50 if it has a function of distributing the coins C conveyed from the coin discriminating section 30 into their respective denominations in response to the denomination signal sent from the coin discriminating section 30 to send the coins C thus discriminated to the coin storing section 60.
The coin storing section 60 is a section for storing the coins C that have been distributed into their respective denominations by the coin distributing section 50 so as to be separated from each other corresponding to the respective denominations. Here, the coin distributing section 60 comprises storing boxes 62 provided for the respective denominations, the total number of which is equal to the number of the denominations (here, eight), and an overflow box 64. The coins C that have been sent to the coin storing section 60 by way of the different distribution gates 59 for the respective denominations and their different paths fall downward to the inside of the corresponding storing boxes 62 and stored therein. If the total number of the coins C stored in any one of the storing boxes 62 reaches a predetermined number, numbers more than the predetermined one are regarded as “overflow” and a further storing operation is restricted. At this time, only the distribution gate 59 corresponding to the overflow box 64 is opened in the coin distributing section 50 and as a result, all the coins C that are sent after the total number of the coins C reaches the predetermined number are sent and stored in the overflow box 64.
If a coins C is found as a counterfeit one in the coin discriminating section 30, the distribution gate 59 corresponding to the counterfeit coin C thus found is opened and the said counterfeit coin C is sent to a conveying belt 72 provided in the coin discharging section 70 (which will be explained later) by way of a dedicated path, thereby being discharged into the dispensing tray 80 without storing in the coin storing section 60. In this way, the coin depositing operation is completed.
The structure and function of the coin storing section 60 are not limited to those described here. Any other device or mechanism may be used as the coin storing section 60 if it has a function of storing the coins C that have been distributed into their respective denominations by the coin distributing section 50 so as to be separated from each other corresponding to the respective denominations.
The coin discharging section 70 is a section for combining the coins C that have been stored in the storing boxes 62 in the coin distributing section 60 according to a dispensing instruction sent from the outside and conveying the coins C thus combined to the outside (concretely, onto the dispensing tray 80). Here, the coin discharging section 70 comprises a discharging belt 72 bridged between a driving roller 74 and a driven roller 76, a motor 78 for driving the driving roller 74, and a pair of guide plates 79 arranged over the discharging belt 72 so as to have an approximately equal interval to the width of the belt 72 along the conveying direction. The coin discharging section 70 opens the dispensing gates (not shown) provided in the storing boxes 62 according to a dispensing instruction transmitted from the outside, thereby making the coins C that are stored in the corresponding boxes 62 of the coin distributing section 60 fall onto the belt 72. Thereafter, the belt 72 is moved by driving the motor 78 to convey the coins C that are placed on the belt 72 to the dispensing tray 80. In this way, the coin dispensing operation is completed.
The structure and function of the coin discharging section 70 are not limited to those described here. Any other device or mechanism may be used as the coin discharging section 70 if it has a function of combining the coins C stored in the storing boxes 62 in the coin distributing section 60 according to a dispensing instruction sent from the outside and conveying the coins C thus combined to the outside (the dispensing tray 80).
Next, the structure of the coin processing apparatus 10 (i.e., the coin introducing section 10a) will be explained below with reference to
As explained above, the coin introducing section 10a of the coin depositing/dispensing machine 1 is formed by the coin processing apparatus 10 according to the embodiment of the present invention. In other words, the coin processing apparatus 10 is incorporated into the coin depositing/dispensing machine 1 as the coin introducing section 10a thereof. The coin introducing section 10a has the structure shown below.
The coin processing apparatus 10 comprises a coin conveying section 100 and a coin agitating section 200. The coin agitating section 200 serves as a coin congestion suppressing section for suppressing a congestion of coins C that is generated during conveyance by the coin conveying section 100.
The coin conveying section 100 is a section for conveying the coins C that have been thrown through the coin inlet 12 in the predetermined conveying direction indicated by the arrows shown in
As shown in the exploded perspective view of
The coin conveying section 100 further comprises a base frame 120 and an introducing chute 114. The base frame 120 comprises a pair of frame plates 122 and 124 disposed at a predetermined interval, and a connecting pin 126 that is located between the frame plates 122 and 124 and that connects the plates 122 and 124 to each other. On the base frame 120, a conveying belt 104 bridged between a driving roller 160 and a driven roller 162, a motor 130 that drives rotatively the driving roller 160, and a reversing roller 108 (which will be explained later) for conveying the coins C in an opposite direction to the conveying direction of the conveying belt 104 are mounted. On the lower surface of the base frame 120, the introducing chute 114 is fixed. The introducing chute 114 is used for sending the coins C that have been introduced into the coin conveying section 100 to the coin separating and delivering section 20 which is provided below the chute 114. The base frame 120 and the chute 114, and the conveying belt 104, the motor 130, and the reversing roller 108 that are mounted on the base frame 120 are fixed in the inside of the front end part of the casing 5. The conveying belt 104, which is located right under the coin inlet 102, is extended in the forth and back direction of the coin depositing/dispensing machine 1 (i.e., in the longitudinal direction of the machine 1). Thus, as seen from
The aforementioned structure of the coin conveying section 100 will be explained below in more detail with reference to
As shown in
The reversing roller 108 is rotatably supported by the base frame 120 in such a manner as to be approximately horizontal. The roller 108 is located at a position right over the rear end (i.e., the left end in
As shown in
The rotation shaft whose one end is connected to the driven pulley 140 is rotatably supported by the base frame 120, and the other end of this shaft is connected to a bevel gear 164, as shown in
Frame members 127 and 129 are attached to the rear end portion of the base frame 120. The frame member 127, which is located at a rearward position with respect to the reversing roller 108, supports the frame plates 122 and 124 at their upper end portions. The top (i.e., the upper end portion) of the chute 114 is located to be opposed to the gap (i.e., the introducing port 116) formed between the motor 130 and the conveying belt 104. The frame member 129, which is located at a rearward position with respect to the frame member 127, supports the frame plates 122 and 124 at their rear end portions.
A rotary encoder 136 is fixed to the output shaft 132 of the motor 130. An optical sensor 138 is attached to the frame member 127 at an opposing position to the encoder 136. An optical beam emitted from a light source (not shown) is detected by the sensor 138 by way of the encoder 136, thereby monitoring constantly the rotation number of the output shaft 132 of the motor 130.
As clearly shown in
The protrusion 106a has a shape like a triangular prism which is laid on the conveying surface of the conveying belt 104 as a whole, and the cross-sectional shape of the protrusion 106a perpendicular to the conveying surface (i.e., the upper surface of the belt 104) is approximately right-angled triangular. In other words, the inclined top face of the protrusion 106a, which corresponds to the hypotenuse of the right-angled triangular cross-section, is extended diagonally backward and downward along the moving direction (i.e., the conveying direction) of the belt 104. Thus, the rear end of the inclined face of the protrusion 106a reaches the conveying surface of the belt 104. This means that the height of the top face of the protrusion 106a gradually decreases along the straight line extending from the driving roller 160 to the driven roller 162. Moreover, the vertical front face of the protrusion 106a, which corresponds to the vertical line of the right-angled triangular cross-section, is located on the side of the driving roller 160 and intersects with the upper surface (i.e., the conveying surface) of the belt 104 at approximately right angles. The reason why such the cross-sectional shape is adopted is to contact or engage the vertical front face of the protrusion 106a with the rear end of a coin C which is placed on the conveying surface at a forward position with respect to the protrusion 106a, thereby making it sure to push the coin C forward by the movement of the belt 104.
In this embodiment, only the pair of protrusions 106a and 106b is formed on the conveying surface of the conveying belt 104. This is why coins C need to be placed on the conveying surface in their lying state in order for the coins C to pass through the introducing port 106 and therefore, an obstacle will arise if the protrusions are formed at more positions. However, two or more pairs of protrusions may be formed if such an obstacle is prevented, and the layout of the protrusions on the conveying surface may be adjusted optionally.
As shown in
Furthermore, in this embodiment, the driving roller 160 and the driven roller 162, which are provided for rotatively driving the conveying belt 104, can convey the coins C not only in the aforementioned conveying direction (i.e., the direction indicated by the arrows in
The coin agitating section 200 is a section for agitating the coins C existing in the coin receiving chamber 118 which is formed between the coin inlet 12 and the conveying surface of the conveying belt 104 at a position right below the inlet 12, thereby quickly eliminating a coin congestion caused by the coins C which have turned into a Tawara state and/or which have induced a Keirin phenomenon after supplied onto the conveying belt 104 through the port 12. It may be said that the coin agitating section 200 is a mechanism having such the function as described here. The coin agitating section 200 serves as a coin congestion suppressing section or means.
As shown in
The pair of screw-like members 202a and 202b, which is rotatably supported by the support 103, has a roll or function of forcing the coins C placed on the right and left sides of the conveying belt 104 in their lying or standing state to move in the opposite direction to the conveying direction, thereby quickly eliminating a coin congestion caused by the coins C which have turned into a Tawara state and/or which have induced a Keirin phenomenon after supplied onto the conveying surface of the belt 104 through the port 12. Therefore, each of the screw-like members 202a and 202b serves as a “coin moving member”.
Next, the structure of the screw-like members 202a and 202b will be explained below with reference to
The screw-like member 202a, which is located on the right side of the conveying belt 104, has an approximately cylindrical shape as a whole. A spiral projection 204a is formed on the outer surface of the member 202a so as to stretch the full length thereof. The projection 204a has three apertures 204aa formed at predetermined intervals along the spiral of the projection 204a. The direction of the spiral of the projection 204a is determined in such a way that a coin C which is engaged with any position of the projection 204a is moved in the opposite direction to the conveying direction of the conveying belt 104 based on the relation with the rotation direction of the member 202a. In this embodiment, the rotation direction of the member 202a is determined in such a way that the member 202a is rotated from the upside toward the downside on the opposite side to the belt 104 and at the same time, the spiral direction of the projection 204a is determined in such a way that the projection 204a has a right-handed spiral from the upstream-side end portion of the member 202a toward the downstream-side end portion thereof. The projection 204a serves as an “operating portion (of the coin moving member)”.
A hole is formed to penetrate through the screw-like member 202a from its upstream-side end to its downstream-side end so that the rotation shaft 210a can be insert into the inside of the member 202a and fit to the same. Moreover, as shown in
By adopting such the structure as described above, the rotation shaft 210a and the screw-like member 202a can be unified easily and at the same time, both of the rotation shaft 210a and the screw-like member 202a can be rotated integrally in the predetermined direction (i.e., the direction that makes the coins C to move in the opposite direction to the conveying direction) due to the rotation of the driven gear 232, while the shaft 210a is idled in the opposite direction to the aforementioned predetermined direction so as not to rotate the screw-like member 202a (see
The structure of the screw-like member 202b is the same as that of the screw-like member 202a. Specifically, the screw-like member 202b, which is located on the left side of the conveying belt 104, has an approximately cylindrical shape as a whole. A spiral projection 204b is formed on the outer surface of the member 202b so as to stretch the full length thereof. The projection 204b has three gaps 204bb formed at predetermined intervals along the spiral of the projection 204b. The direction of the spiral of the projection 204b is determined in such a way that a coin C which is engaged with any position of the projection 204b is moved in the opposite direction to the conveying direction of the conveying belt 104 based on the relation with the rotation direction of the member 202b. In this embodiment, the rotation direction of the member 202b is determined in such a way that the member 202b is rotated from the upside toward the downside on the opposite side to the belt 104 and at the same time, the spiral direction of the projection 204b is determined in such a way that the projection 204b has a left-handed spiral from the upstream-side end portion of the member 202b toward the downstream-side end portion thereof. As seen from the description presented here, the rotation direction of the screw-like member 202b is opposite to that of the screw-like member 202a, and the spiral direction of the spiral projection 204b of the screw-like member 202b is also opposite to that of the spiral projection 204a of the screw-like member 202a. The projection 204b also serves as an “operating portion (of the coin moving member)”.
A hole is formed to penetrate through the screw-like member 202b from its upstream-side end to its downstream-side end so that the rotation shaft 210b can be insert into the inside of the member 202b and fit to the same. Moreover, as shown in
By adopting such the structure as described above, the rotation shaft 210b and the screw-like member 202b can be unified easily and at the same time, both of the rotation shaft 210b and the screw-like member 202b can be rotated integrally in the predetermined direction (i.e., the direction that makes the coins C to move in the opposite direction to the conveying direction) due to the rotation of the driven pulley 226, while the shaft 210b is idled in the opposite direction to the aforementioned predetermined direction so as not to rotate the screw-like member 202b (see
By setting the structure and the rotation direction of the screw-like-members 202a and 202b and the spiral direction of the spiral projections 204a and 204b as describe above, the coins C placed on the conveying surface of the belt 104 can be surely moved in the opposite direction to the conveying direction of the belt 104 only when needed.
As shown in
Similarly, the pair of lower side brushes 208a and 208b is fixed to the support 103. The roll or function of the lower side brushes 208a and 208b is to prevent the coins C that are pushed laterally (i.e., in the horizontal direction perpendicular to the conveying direction) from going out of the coin receiving chamber 118 (or the conveying surface) positioned over the conveying belt 104 while allowing the spiral projections 204a and 204b to rotate so as to continuously change their positions with the rotation of the screw-like members 202a and 202b. For this reason, the lower parts of the brushes 208a and 208b are formed by a flexible material (e.g., a synthetic resin with flexibility) so as to be easily deformed due to the contact of the projections 204a and 204b. The gaps between the brushes 208a and 208b and the corresponding screw-like members 202a and 202b are set to be larger than the maximum height of the projections 204a and 204b.
The pair of covers 250a and 250b is fixed to the base frame 120 so as to be positioned respectively at the left and right sides thereof. The roll or function of the covers 250a and 250b is to protect the pair of upper brushes 206a and 206b, the pair of screw-like members 202a and 202b, and the pair of lower brushes 208a and 208b by covering them from their outside, and to surely prevent the coins C that are pushed laterally from going out of the conveying surface or the coin receiving chamber 118 formed on the conveying belt 104. To prevent the coins C from going out, each of the covers 250a and 250b has three protrusions 250aa and 250bb, as clearly shown in
The pair of element supports 252a and 252b is attached to the outer surfaces of the pair of corresponding covers 250a and 250b, respectively. The element support 252a is a member for supporting light-emitting elements 192 that are aligned at predetermined intervals along the conveying surface of the conveying belt 104 at slightly higher positions than the conveying surface. The element support 252b is a member for supporting light-receiving elements 194 that are aligned at the same intervals as the light-emitting elements 192 along the conveying surface of the conveying belt 104 at slightly higher positions than the conveying surface. Each of the light-receiving elements 194 is designed to receive an optical beam emitted from a corresponding one of the light-emitting elements 192. (To realize this, two gaps through which the optical beam can pass are respectively formed between the lower brush 208a and the conveying surface of the belt 104 and between the lower brush 208b and the same surface.) If a coin C is present on the conveying surface of the belt 104, the optical beam is blocked by the coin C and as a result, the amount of the light received by a corresponding one of the light-receiving elements 194 becomes zero or decreases drastically. Thus, by monitoring the ON and OFF operation of each light-receiving element 194, the existence or absence of coins C on the conveying surface can be detected. Accordingly, the control operation that the rotation of the screw-like members 202a and 202b is stopped if no coin exists on the conveying surface can be performed. The combination of the light-emitting elements 192 and the light-receiving elements 194 constitutes a second coin detecting section 190 for optically detecting coins C placed on the belt 104. In addition, the second coin detecting section 190 belongs to the coin conveying section 100, not to the coin agitating section 200. The second coin detecting section 190 may be omitted.
Next, the structure for rotatively driving the aforementioned pair of screw-like members 202a and 202b (the rotation shafts 210a and 210b) will be explained below with reference to
The aforementioned pair of screw-like members 202a and 202b is rotatively driven by the motor 130 that rotatively drives the conveying belt 104 in the following way. This is to reduce the fabrication cost. However, it is needless to say that the pair of screw-like members 202a and 202b may be rotatively driven by another motor instead of the motor 130.
As seen from
The driving pulley 224 is fixed to the driving shaft 222 which is rotatably supported by the frame member 128. The bevel gear 220 is fixed to the opposite end portion of the driving shaft 222 to the driving pulley 224 and is meshed with the bevel gear 164. As explained above, the bevel gear 164 is rotatably driven by the rotation of the output shaft 132 of the motor 130 and therefore, it is seen that both of the screw-like members 202a and 202b are rotatably driven in the same direction by the rotation of the output shaft 132 of the motor 130.
In this embodiment, as explained above, all of the screw-like members 202a and 202b, the reversing roller 108, and the driving roller 160 and the driven roller 162 for rotatably driving the conveying belt 104 are rotated by the single motor 130; thus, the fabrication cost can be reduced.
Next, the coin processing operation of the coin processing apparatus 10 according to the embodiment of the invention having the aforementioned structure and function will be explained below with reference to
(a) First, how coins C placed on the conveying surface of the belt 104 in their lying state are moved in the coin receiving chamber 118 is shown in
As seen from
Next, (b) while a group CC of coins are staying on the conveying surface of the conveying belt 104 in its Tawara state, how the coins C placed on the conveying surface in their lying state are moved in the coin receiving chamber 118 is shown in
As seen from
In this case, the coin group CC staying in the Tawara state is not conveyed; however, as explained above, the coins C placed on the conveying surface in their lying state can be conveyed forward successively. As explained later, the coin group CC staying in the Tawara state is gradually put into disorder by the pair of screw-like members 202a and 202b of the coin agitating section 200 and therefore, the coin group CC staying in the Tawara state also will be able to be conveyed forward successively.
Subsequently, (c) how coins C placed on the conveying surface of the belt 104 in their standing state at its right and left sides are moved in the coin receiving chamber 118 is shown in
As seen from
When the coins C are turned into the lying state or the state near the lying state on the conveying surface in this way, they are moved forward by the movement of the belt 104 and then, fall on the chute 114 through the introducing port 116 from the belt 104. This is because a friction force is generated between the coins C and the conveying surface of the belt 104 or because the pair of protrusions 106a and 106b formed on the conveying surface of the belt 104 abuts against the rear ends of the coins C to thereby push them forward. The subsequent action of the coins C fallen on the chute 114 is the same as that described above with reference to
Finally, (d) how two coins C secede from a coin group CC that is staying on the conveying surface of the belt 104 in its Tawara state near the front end portion of the conveying surface, where the two coins C are respectively located at the right and left side ends of the group CC, is shown in
As seen from
As explained above in detail, with the coin processing apparatus 10 according to the embodiment of the present invention, there are provided with the coin conveying section 100 for separating the coins C that have been thrown through the coin inlet 12 from each other and conveying them having a desired attitude, and the coin agitating section 200 for agitating the coins C that are being conveyed by the coin conveying section 100 to suppress a congestion of the coins C thus conveyed. The coin agitating section 200 serves as the coin congestion suppressing section.
Moreover, the coin conveying section 100 comprises the conveying belt 104 for conveying the coins C that have been thrown through the coin inlet 12 and that are placed on the conveying surface in the predetermined conveying direction, the motor 130 for moving the belt 104 in the conveying direction, and the reversing roller 108 that is mounted to be opposed to the conveying surface at the predetermined position thereon and that forms the introducing port 116 for allowing the coins C having the desired attitude to selectively pass through in cooperation with the conveying surface.
The reversing roller 108 is rotated in response to contact with the coin or coins C placed on the conveying surface in such a way as to move the coin or coins C placed on the conveying surface in the opposite direction to the conveying direction. The pair of protrusions 106a and 106b (each of which serves as a coin pusher) is formed on the conveying surface in order to push the coins C that are placed on the conveying surface in their lying state or approximately lying state (which is a state close to the lying state caused by another coin) toward the introducing port 116.
The coin agitating section 200 comprises the pair of screw-like members 202a and 202b that is mounted at the right and left sides of the conveying belt 104 along the conveying direction and that has the spiral projections 204a and 204b formed respectively on the outer surfaces of the members 202a and 202b. The members 202a and 202b are rotatively driven around their central axes in such a way that the coins C placed on the conveying surface in their standing state are engaged with any one of the spiral projections 204a and 204b of the members 202a and 202b to be moved toward the opposite side to the introducing port 116, in which the coins C are designed to topple down naturally toward the conveying surface during the conveyance.
Therefore, if the coins C placed on the conveying surface in their standing state are engaged with any one of the spiral projections 204a and 204b of the screw-like members 202a and 202b in the state where the pair of screw-like members 202a and 202b is rotatively driven around their central axes, the said coins C are moved toward the opposite side to the introducing port 116 so as to topple down naturally toward the conveying surface during the conveyance. For this reason, if the coin group CC is gathered on the conveying surface of the conveying belt 104 to thereby induce a Tawara state and/or a Keirin phenomenon, there is an increase in the possibility that the coins C placed at the two ends (i.e., the right and left sides) of the group CC are contacted and engaged with the adjoining one of the spiral projections 204a and 204b. If so, the coins C at the ends of the group CC are moved on the conveying surface toward the opposite side to the introduction port 116 to thereby topple down naturally toward the conveying surface during this movement. Once such the action occurs, the group CC existing in a Tawara state and/or inducing a Keirin phenomenon is more likely to sway laterally (i.e., in the horizontal direction perpendicular to the conveying direction); thus, the aforementioned action will occur repeatedly and finally, the Tawara state and the Keirin phenomenon will disappear.
Accordingly, even if a lot of coins C that are thrown through the coin inlet 12 are gathered on the conveying belt 104 to result in a Tawara state or the coins C of the coin group CC on the belt 104 are contacted with the reversing roller 108 to be rotated on their own axes to thereby induce a Keirin phenomenon, the Tawara state and the Keirin phenomenon can be eliminated quickly and surely.
Moreover, since the pair of protrusions 106a and 106b is formed on the conveying surface of the belt 104, the coins C placed on the conveying surface in their lying state or approximately lying state can be surely pushed toward the introducing port 116 by engaging the coins C in question with at least one of the protrusions 106a and 106b. This is applicable in any case regardless of the presence or absence of the coins C that are in a Tawara state and/or a Keirin phenomenon near the reversing roller 108.
Furthermore, the aforementioned mechanism or operation principle that the Tawara state and/or the Keirin phenomenon is/are eliminated by the screw-like members 202a and 202b is effective even (i) in the case where additional coins are overlapped or stacked on a group CC of coins C that have induced a Tawara state and/or a Keirin phenomenon on the conveying surface and (ii) in the case where additional coins are placed on the upstream side of the conveying surface with respect to a group CC of coins C that have induced a Tawara state or a Keirin phenomenon on the conveying surface.
Accordingly, a congestion of coins can be eliminated quickly and surely even in the aforementioned cases (i) and (ii).
On the other hand, with the coin depositing/dispensing machine 1 according to the embodiment of the present invention, since the aforementioned coin processing apparatus 10 is incorporated as the coin introducing section 10a, the same advantageous effects are obtained because of the same reason as that of the coin processing apparatus 10.
Specifically, even if a congestion of coins C is caused by a group of coins C that have induced a Tawara state and/or a Keirin phenomenon on the conveying surface of the conveying belt 104, the Tawara state and/or the Keirin phenomenon can be eliminated in a short time. This means that the congestion of coins caused by a group of coins C that have induced a Tawara state and/or a Keirin phenomenon can be eliminated quickly and surely. Furthermore, a congestion of coins C can be eliminated quickly and surely even in the aforementioned cases (i) and (ii).
Accordingly, with the coin depositing/dispensing machine 1, the operation efficiency of the coin depositing/dispensing process can be raised and at the same time, the convenience for users can be improved and the burden of the persons in charge of coin depositing/dispensing can be reduced compared with the prior art.
In addition to the aforementioned advantageous effects, the coin processing apparatus 10 according to the embodiment of the present invention has the following advantageous effects.
Since the screw-like members 202a and 202b that are rotatively driven around their axes are provided as the coin moving members and the rotatively driving of the conveying belt 104 and that of the screw-like members 202a and 202b are realized by the single motor 130, the structure of the coin processing apparatus 10 is simplified and the fabrication cost thereof is lowered.
Moreover, the screw-like members 202a and 202b are designed to be easily integrated with the corresponding rotation shafts 210a and 210b using the one-way clutches 207a and 207b according to the necessity so that the members 202a and 202b and the corresponding shafts 210a and 210b are rotated integrally in the predetermined direction (i.e., the direction in which the coins C are moved in the opposite direction to the conveying direction) while the shafts 210a and 210b are idled in the opposite direction to the aforementioned predetermined direction so as not to rotate the screw-like members 202a and 202b. Thus, it is possible to conduct such a suitable control that the rotation of the screw-like members 202a and 202b is temporarily stopped to stop the rearward movement of the coins C temporarily while keeping the rotation of the belt 104 and that of the members 202a and 202b using the single motor 130 when the belt 104 is stopped or moved in the opposite direction to the conveying direction.
The aforementioned embodiments are embodied examples of the present invention. Thus, it is needless to say that the present invention is not limited to the said embodiments and any other modification is applicable to the embodiments without departing the spirit of the invention.
For example, in the aforementioned embodiments, the circular coin inlet 12 is provided horizontally at the position right over the conveying belt 104 (i.e., the conveying surface) so as to be spaced apart from the belt 104 at a predetermined distance, thereby forming the coin receiving chamber 118 right under the coin inlet 12. However, the present invention is not limited to this. The positional relationship between the belt 104 or the conveying surface and the coin inlet 12 may be optionally changed. It is sufficient for the present invention to have the coin receiving chamber 118 on or over the belt 104 or the conveying surface.
In the aforementioned embodiments, the coin inlet cover is attached to the coin inlet 12 to increase the total amount of the coins C that can be thrown into the coin receiving chamber 118 in a lump. However, the present invention is not limited to this. The cover 7 may be omitted, and the distance between the coin inlet 12 and the belt 104 may be made larger to increase the total amount of the coins C that can be thrown into the chamber 118 in a lump.
In the aforementioned embodiments, the upper and lower side brushes 206a and 208a are arranged respectively at the upper and lower positions of the screw-like member 202a and the upper and lower side brushes 206b and 208b are arranged respectively at the upper and lower positions of the screw-like member 202b, and the gaps formed between the upper and lower side brushes 206a and 208a and the member 202a and the gaps formed between the upper and lower side brushes 206b and 208b and the member 202b are blocked while allowing the spiral projections 204a and 204b of the members 202a and 202b to pass through the corresponding gaps in question. However, the present invention is not limited to this. Any other structure may be used for this purpose.
In the aforementioned embodiments, the screw-like members 202a and 202b are provided at the right and left sides of the conveying belt 104 or the conveying surface as the coin moving members; however, the present invention is not limited to this. The screw-like member may be provided at only the right or left side of the conveying belt 104. In this case, although it takes a longer time to eliminate the Tawara state and/or the Keirin phenomenon of the coin group CC than the case where the screw-like members 202a and 202b are provided at the right and left sides of the belt 104, the Tawara state and/or the Keirin phenomenon in question can be eliminated.
In the aforementioned embodiments, since the spiral projections 204a and 204b of the screw-like members 202a and 202b have the apertures 204aa and 204bb formed along the spirals of the projections 204a and 204b, respectively, the occupation areas of the projections 204a and 204b are respectively larger than the occupation areas of the apertures 204aa and 204bb. However, this relationship may be reversed, specifically, the occupation areas of the apertures 204aa and 204bb may be respectively larger than the occupation areas of the projections 204a and 204b. In this case, a structure that a plurality of protrusions are arranged on a virtual spiral that is formed on the outer surface of a cylindrical member at predetermined intervals is obtained, in which the arrangement pitch of the protrusions is set to be, for example, less than the minimum coin diameter that can be handled in order that the protrusions may be engaged with the coins placed on the conveying surface to thereby move these coins upstream in the conveying direction (i.e., backward). If such the concept is pushed ahead furthermore, a structure that a plurality of pin-shaped parts are arranged on a virtual spiral that is formed on the outer surface of a cylindrical member at predetermined intervals is obtained; such the structure may be used for the aforementioned screw-like member. Briefly speaking, it is sufficient for the present invention that the screw-like members 202a and 202b with the spiral projections 204a and 204b can be engaged with the coins C in their standing state to move the said coins C upstream in the conveying direction (i.e., backward); the concrete structure of the screw-like members 202a and 202b may be changed optionally.
Further in addition, as the aforementioned coin moving member, any other structure may be used instead of the screw-like members 202a and 202b used in the aforementioned embodiments. For example, (a) a structure that a plurality of projections, which serve as the operating portion of the coin moving member for engaging with a coin or coins C to move the said coin or coins, are arranged at intervals on the outer surface of a cylindrical member that is rotatively driven in a horizontal plane, (b) a structure that a plurality of projections, which serve as the operating portion of the coin moving member, are arranged at intervals on the outer surface of an endless belt that is rotatively driven in a horizontal plane, or (c) a structure comprising a plurality of brush-like parts that is rotatively driven in a horizontal plane, in which the top ends of the brush-like parts are used as the operating portion of the coin moving member, may be used. In this way, any structure may be used for the coin moving member if it can be engaged with a coin or coins C in its/their standing state on at least one of the right and left sides of the conveying surface to move the said coins C upstream in the conveying direction (i.e., backward).
The coin processing apparatus and the coin depositing/dispensing machine according to the present invention are applicable not only to coins as currency but also coin equivalents such as token and medals. Moreover, the coin processing apparatus according to the present invention may be used for any other apparatus or machine than the coin introducing section for the coin depositing/dispensing machine if there is a possibility that a Tawara state and/or a Keirin phenomenon of coins is/are caused to result in a congestion of coins on the conveying belt in the coin receiving chamber for receiving coins that are put in through the coin inlet.
While the preferred forms of the present invention have been described, it is to be understood that modifications will be apparent to those skilled in the art without departing from the spirit of the invention. The scope of the present invention, therefore, is to be determined solely by the following claims.
