Description

[Technical Field]

[0001] The present invention relates to a coin processing device, and more particularly to a coin processing device that is used as a change dispenser. [Background technology]

[0002] Conventionally, a coin processing device with a built-in lift-up section for the purpose of reducing the depth dimension has been proposed in Patent Document 1. The lift-up section extends in a manner that gradually slopes upward as it approaches the dispensing port, and transports coins upward to be dispensed from the dispensing port. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-154439 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned coin processing device, in order to reduce the depth dimension, the inclination angle of the lift-up section relative to the horizontal plane needs to be 40° or more, and it is required that the lift-up section be able to transport coins one by one smoothly.

[0005] Here, the lift-up section is configured by a lift-up conveying belt stretched endlessly around a pair of lift-up conveying pulleys arranged along the conveying direction, and as the lift-up conveying pulleys rotate, the lift-up conveying belt displaces along its own extension direction to convey coins upward.

[0006] Therefore, as shown in Fig. 10, it is conceivable to transport coins K by increasing the protruding height of protrusions 52 provided on the surface of lift-up transport belt 51. However, with the configuration shown in Fig. 10, there is a risk that coins K may roll between the protruding portions 52, which is not preferable.

[0007] 11(a) and 11(b), it is possible to attach conveying pieces 55 to protruding portions 54 of a lift-up conveying belt 53 and surround the conveying pieces 55 with guide rails 56 in a manner that reduces the gap between the conveying pieces 55 and the coins K. In such a configuration, it is possible to convey the coins K without rolling even if the inclination angle is 40° or more.

[0008] However, in such coin processing devices, when performing an empty confirmation operation to determine whether there are any coins remaining in the lift-up section, for example, because the number of coins dispensed from the storage cabinet does not match the number of coins dispensed from the dispensing port, the following problem occurred.

[0009] In other words, the conveyor belt must be displaced in the opposite direction to when dispensing until it is detected by the remaining bill detection sensor installed in the lift-up section, which may lengthen the time required for the empty confirmation operation. Such a lengthy empty confirmation operation ultimately results in an excessively long dispensing time, which is undesirable.

[0010] In view of the above circumstances, an object of the present invention is to provide a coin processing device that can reduce the depth dimension and shorten the dispensing time. [Means for solving the problem]

[0011] In order to achieve the above object, the coin processing device according to the present invention identifies the authenticity and denomination of deposited coins, and stores coins identified as genuine coins in the storage vaults corresponding to each denomination, while transporting coins dispensed from any storage vault in response to a dispensing instruction by a dispensing transport unit and then transporting them upward by a lift-up unit to dispense them from a dispensing port, the lift-up unit comprising: a first lift-up transport belt that is endlessly stretched around a pair of lift-up transport pulleys arranged along the transport direction, with transport pieces erected at predetermined intervals along the extension direction of the lift-up unit on its surface, and on which coins can be placed at an upper portion between the pair of lift-up transport pulleys; and a second lift-up transport belt that is endlessly stretched around the pair of lift-up transport pulleys. Both are equipped with a second lift-up conveying belt having protrusions on its surface at the same intervals as the conveying pieces along its extension direction, and which is displaced along its extension direction by the rotation of the lift-up conveying pulley, and when the driving source, a lift-up actuator, is driven in a forward rotation, the protrusions press against the conveying pieces, thereby displacing the first lift-up conveying belt so that the upper portion is closer to the withdrawal port, while when the lift-up actuator is driven in a reverse rotation, the protrusions press against the conveying pieces, thereby displacing the first lift-up conveying belt so that the upper portion is away from the withdrawal port.

[0012] Furthermore, in the coin processing device according to the present invention, the second lift-up conveyor belts are arranged in pairs on both sides of the first lift-up conveyor belt. [Effects of the Invention]

[0013] According to the present invention, the lift-up unit includes a first lift-up conveyor belt that is endlessly stretched on a pair of lift-up conveyor pulleys arranged along the conveying direction, has conveying pieces standing on its surface at predetermined intervals along its extension direction, and is capable of placing coins at an upper portion between the pair of lift-up conveyor pulleys, and a second lift-up conveyor belt that is endlessly stretched on the pair of lift-up conveyor pulleys, has protruding pieces standing on its surface at the same intervals as the conveying pieces along its extension direction, and is displaced along its extension direction by the rotation of the lift-up conveyor pulleys, and the second lift-up conveyor belt is driven by a lift-up actuator that rotates in the forward direction. When driven, the protrusion presses the conveying piece, displacing the first lift-up conveying belt so that the upper part is closer to the withdrawal port, while when the lift-up actuator is driven in reverse rotation, the protrusion presses the conveying piece, displacing the first lift-up conveying belt so that the upper part is away from the withdrawal port.Therefore, if no gaps occur between all of the conveying pieces and the protrusion when the lift-up actuator is driven in reverse rotation, it means that no coins remain, and by quickly determining that the coin is empty, the time required for the empty confirmation operation can be shortened, resulting in the effect of reducing the depth dimension while shortening the withdrawal time.

DETAILED DESCRIPTION OF THE INVENTION

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a coin processing device according to the present invention will be described in detail below with reference to the accompanying drawings.

[0016] 1 and 2 are perspective views showing a money handling machine to which a coin processing device according to an embodiment of the present invention is applied. The money handling machine 1 shown here is connected to a host device (not shown) such as a POS (Point Of Sales) register in a store such as a supermarket or convenience store, and includes a device main body 2.

[0017] The device main body 2 is a rectangular housing having a front opening 2a at the front and a top opening (not shown) at the top, and is movable with multiple casters 2d (four in the illustrated example) provided on the bottom 2c.

[0018] The device body 2 has a front opening 2a that can be opened and closed by a door 3, and a top opening that can be opened and closed by a top panel 4.

[0019] The door body 3 includes a front cover 3a and a front door 3b. The front cover 3a is pivotally supported forward of the top opening. When the front cover 3a swings upward, it opens the upper part of the front opening 2a, and when it swings downward, it closes the upper part of the front opening 2a.

[0020] The front door 3b is pivotally supported at the front end portion of the left edge of the device main body 2. When the front door 3b swings forward, it opens the lower portion of the front opening 2a, i.e., the portion that cannot be closed by the front cover 3a, and when it swings backward, it closes the lower portion of the front opening 2a.

[0021] The front door 3b is provided with a locking mechanism 3c, and when this locking mechanism 3c is in a locked state, the front door 3b is kept in a state in which the lower part of the front opening 2a is blocked, while when the locking mechanism 3c is in an unlocked state, the front door 3b becomes able to swing forward.

[0022] Moreover, the front door 3b has a function of pressing a part of the front cover 3a in the closed state, and when the locking mechanism 3c is in the locked state, the front cover 3a is maintained in the closed state.

[0023] The top panel portion 4 is slidable in the front-rear direction, and opens the top opening by sliding it rearward, and closes the top opening by sliding it forward.

[0024] As shown in Fig. 2, the apparatus main body 2 accommodates a coin processing device 10 together with a banknote processing device 5. The banknote processing device 5 performs operations such as depositing and dispensing banknotes.

[0025] Fig. 3 is a perspective view showing the external configuration of the coin processing device 10 shown in Fig. 2, i.e., the coin processing device 10 according to an embodiment of the present invention, and Fig. 4 is a schematic diagram showing the internal structure of the coin processing device 10 according to an embodiment of the present invention. The internal structure of the coin processing device 10 will be explained by function using Figs. 3 and 4. In the following, the configuration of each part of the coin processing device 10 will be explained along the directions indicated in Fig. 3.

[0026] The coin processing device 10 illustrated here can be pulled out forward from a front opening 2a of the device main body 2 by a pull-out mechanism (not shown), and includes a coin transport mechanism 20.

[0027] <Coin transport mechanism 20> The coin transport mechanism 20 has a deposit transport section 22, a deposit temporary holding section 24, an inspection temporary holding section 26, a sorting section 28, a storage cabinet 30, a withdrawal transport section 32, a withdrawal temporary holding section 34, a direction change section 36, a lift-up section 38, and a group of switching gates 40.

[0028] The deposit transport unit 22 transports coins that are inserted through the deposit port 21 and detected by an insertion detection sensor (not shown). The deposit port 21 is an opening for inserting coins, and is exposed to the outside through a coin deposit opening 3d formed in the front cover 3a. This deposit transport unit 22 is provided with a coin validation unit 22a. The coin validation unit 22a identifies the authenticity and denomination of coins.

[0029] Deposit escrow section 24 is disposed below deposit transport section 22 and is connected to deposit transport section 22 via deposit chute 23a. Reconciliation escrow section 26 is disposed below deposit escrow section 24 and is connected to deposit escrow section 24 via connecting chute 25a. Reconciliation escrow section 26 temporarily holds coins that have fallen through connecting chute 25a.

[0030] The sorting unit 28 sorts the coins that have been stored in the inspection temporary storage unit 26 and then transported, by denomination. The storage cabinets 30 are provided for each denomination and store the coins sorted by the sorting unit 28. More specifically, there are six storage cabinets 30, from the rear side: a 1 yen storage cabinet 30a, a 50 yen storage cabinet 30b, a 5 yen storage cabinet 30c, a 100 yen storage cabinet 30d, a 10 yen storage cabinet 30e, and a 500 yen storage cabinet 30f. Each storage cabinet 30 has a feeding unit 301 that feeds the stored coins to the dispensing transport unit 32, and this feeding unit 301 is provided with a discrimination unit 302 that discriminates predetermined discrimination elements, such as the denomination and number of the coins to be dispensed.

[0031] The dispensing transport unit 32 is disposed on the right side of the storage 30. This dispensing transport unit 32 transports coins dispensed from the storage 30 rearward.

[0032] The withdrawal escrow section 34 is disposed on the rear right side of the withdrawal transport section 32, below the deposit escrow section 24. This withdrawal escrow section 34 temporarily stores coins to be withdrawn from a withdrawal port 39, which will be described later.

[0033] The direction changing unit 36 ​​is disposed in front of the withdrawal escrow unit 34. The direction changing unit 36 ​​receives the coins stored in the withdrawal escrow unit 34 one by one and transports them to the lift-up unit 38.

[0034] The lift-up section 38 is disposed on the front side of the direction changing section 36. The lift-up section 38 extends in a manner that gradually slopes upward as it approaches the front, and conveys coins from the rear to the front, that is, conveys coins upward and dispenses them from the dispensing port 39. The configuration of the lift-up section 38 will be described later.

[0035] The withdrawal port 39 is an opening provided above the deposit temporary holding section 24 and below the deposit port 21, and is exposed to the outside through a coin withdrawal opening 3e formed in the front cover 3a. Coins withdrawn from this withdrawal port 39 are paid out to a withdrawal tray 3f provided in the front cover 3a.

[0036] The switching gate group 40 includes a first switching gate 40a, a second switching gate 40b, and a third switching gate 40c. The first switching gate 40a is provided behind (downstream in the conveying direction) the deposit transport unit 22. The first switching gate 40a is switchable between a state in which coins that are being transported by the deposit transport unit 22 and identified as genuine by the validation unit 22a are transported to the deposit chute 23a, and a state in which coins that are being transported by the deposit transport unit 22 and identified as counterfeit by the validation unit 22a are transported to the first refund chute 23b. The first refund chute 23b guides coins from the deposit transport unit 22 to the withdrawal escrow unit 34.

[0037] The second switching gate 40b is provided on the rear side (downstream side in the transport direction) of the deposit escrow section 24. This second switching gate 40b can alternatively switch between a state in which coins stored in the deposit escrow section 24 are transported to the connection chute 25a and a state in which the coins are transported to the second refund chute 25b. Here, the second refund chute 25b guides coins from the deposit transport section 22 to the withdrawal escrow section 34.

[0038] The third switching gate 40c is provided on the rear side (downstream side in the conveying direction) of the dispensing conveying section 32. This third switching gate 40c is capable of selectively switching between a conveying state in which coins conveyed by the dispensing conveying section 32 are conveyed to the dispensing escrow section 34, and a circulating state in which the coins are conveyed to the inspection escrow section 26. The third switching gate 40c is normally in the conveying state.

[0039] The operation of the coin transport mechanism 20 will be briefly described. First, the deposit operation will be described. When a deposit permission command is given from a higher-level device, a coin inserted into the deposit port 21 is detected by an insertion detection sensor, then transported by the deposit transport unit 22, and its authenticity and denomination are identified by the coin validation unit 22a. If the coin is genuine, it is stored in the deposit temporary storage unit 24 via the deposit chute 23a.

[0040] On the other hand, if the coin is not a genuine coin, it is transported to the dispensing escrow section 34 via the first switching gate 40a and the first refund chute 23b. Thereafter, the coin is transported from the dispensing escrow section 34 and the direction changing section 36 to the lift-up section 38, which transports it to the dispensing port 39 and returns it to the dispensing tray 3f.

[0041] Furthermore, when a refund command is given from a higher-level device regarding a coin held in the deposit escrow unit 24, the coin is transported to the withdrawal escrow unit 34 via the second switching gate 40b and the second refund chute 25b. Thereafter, the coin is transported from the withdrawal escrow unit 34 and the direction changing unit 36 ​​to the lift-up unit 38, which then transports the coin to the withdrawal port 39 and returns it to the withdrawal tray 3f.

[0042] When a deposit command is given from a higher-level device regarding coins held in deposit escrow unit 24, the coins held in deposit escrow unit 24 are held in reconciliation escrow unit 26, and then the coins held in reconciliation escrow unit 26 are transported to sorting unit 28, where they are sorted by denomination as they are transported forward. The coins sorted by sorting unit 28 are stored in storage vaults 30 according to their denominations, and then the deposit operation is completed by notifying the higher-level device that deposit has been completed.

[0043] Next, the dispensing operation will be described. When a dispensing command is given from the higher-level device, coins of the denomination corresponding to the dispensing command are fed from the corresponding storage 30 to the dispensing transport unit 32. The coins fed to the dispensing transport unit 32 are transported rearward and sent to the dispensing escrow unit 34 via the third switching gate 40c, which is in a transport state. The coins are then transported from the dispensing escrow unit 34 and the direction changing unit 36 ​​to the lift-up unit 38, which transports them to the dispensing port 39 and dispenses them into the dispensing tray 3f. After the specified coins have been dispensed to the outside in this way, the dispensing operation is completed by notifying the higher-level device that dispensing has been completed.

[0044] The reconciliation operation is an operation for counting the number of coins stored in each storage box 30.

[0045] When a reconciliation command is given from a higher-level device, the feeding unit 301 in the corresponding storage 30 is driven to feed coins from the storage 30 to the dispensing transport unit 32, and the coins are discriminated by the discriminator 302. The coins are then transported rearward by the dispensing transport unit 32 and temporarily stored in the reconciliation temporary storage unit 26.

[0046] The coins stored in the reconciliation temporary storage section 26 are then transported to the sorting section 28, where they are sorted by denomination, and the reconciliation operation is completed by detecting the number of coins and storing them in a designated storage cabinet 30.

[0047] <Lift-up part 38> 5 and 6 are schematic diagrams each showing the configuration of the lift-up unit 38. As shown in these Figs. 5 and 6, the lift-up unit 38 is configured to include a first lift-up conveyor belt 381 and a second lift-up conveyor belt 382.

[0048] The first lift-up conveyor belt 381 is endlessly stretched around a pair of lift-up conveyor pulleys 383 arranged in the conveying direction. Similar to the lift-up conveyor belt shown in Fig. 11, this first lift-up conveyor belt 381 has conveying pieces 384 attached to protruding portions (not shown) as shown in Fig. 6. Note that Fig. 6 shows the conveying pieces 384 attached to the upper portion of the first lift-up conveyor belt 381 between the pair of lift-up conveyor pulleys 383, and the lower portion is not shown.

[0049] Such a first lift-up conveyor belt 381 is stretched around a pair of lift-up conveyor pulleys 383, but does not displace in the extending direction even when the lift-up conveyor pulleys 383 rotate.

[0050] The second lift-up conveyor belt 382 is endlessly stretched between a pair of lift-up conveyor pulleys 383 on both sides of the first lift-up conveyor belt 381. The second lift-up conveyor belt 382 has protrusions 385 standing on its surface along its extension direction at the same intervals as the conveyor pieces 384. The second lift-up conveyor belt 382 is displaced along its extension direction by the rotation of the lift-up conveyor pulley 383.

[0051] Although not shown in the figure, the lift-up section 38 is surrounded by a guide rail in a manner that reduces the gap between the lift-up section 38 and the conveying piece 384. Also, reference numeral 386 in Fig. 5 denotes a residue detection sensor that is constituted by, for example, an optical sensor.

[0052] In the lift-up section 38, the rear lift-up conveying pulley 383 is connected to the lift-up actuator 387, which is the drive source, and is a drive pulley that rotates clockwise as viewed from the left when the lift-up actuator 387 is driven in a forward rotation, and rotates counterclockwise as viewed from the left when the lift-up actuator 387 is driven in a reverse rotation.

[0053] When the rear lift-up conveying pulley 383 rotates clockwise when viewed from the left, the protrusion 385 of the second lift-up conveying belt 382 presses the conveying piece 384, as shown in Figure 5, displacing the first lift-up conveying belt 381 so that the upper portion between the pair of lift-up conveying pulleys 383 is closer to the withdrawal port 39.On the other hand, when the rear lift-up conveying pulley 383 rotates counterclockwise when viewed from the left, the protrusion 385 presses the conveying piece 384, as shown in Figure 7, displacing the first lift-up conveying belt 381 so that the upper portion is away from the withdrawal port 39.

[0054] In the coin processing device 10 having the configuration described above, when the lift-up actuator 387 rotates forward in the lift-up section 38, the protrusion 385 presses the conveying piece 384, and coins placed on the upper part of the first lift-up conveying belt 381 and the second lift-up conveying belt 382 between the lift-up conveying pulley 383 are pressed by the conveying piece 384 and conveyed to the withdrawal port 39.

[0055] In the above-mentioned coin processing device 10, when an empty confirmation operation is performed to determine whether there are any coins remaining in the lift-up section 38 because the number of coins dispensed from the storage 30 does not match the number of coins dispensed from the dispensing port 39, the lift-up actuator 387 is driven to rotate in the reverse direction.

[0056] As a result, the rear lift-up conveying pulley 383 rotates counterclockwise as viewed from the left. When there are no remaining coins in the lift-up section 38, the protruding piece 385 comes into contact with and presses the conveying piece 384 as shown in Fig. 7, and the remaining coin detection sensor 386 turns ON when the conveying piece 384 and the protruding piece 385 pass through its detection area in a state of contact with each other, as shown in (A) of Fig. 8(a).

[0057] 9(a), when a coin K is caught sideways between any of the conveying pieces 384 and the protruding pieces 385, the same gaps will be formed between all of the conveying pieces 384 and the protruding pieces 385. Therefore, the residual detection sensor 386 turns ON when the conveying piece 384 passes through its detection area as shown in FIG. 8(b)(b), and also turns ON when the protruding piece 385 passes through its detection area as shown in FIG. 8(b)(c).

[0058] Furthermore, as shown in Figure 9(b), when a coin K is caught in an upright position between any of the conveying pieces 384 and the protruding pieces 385, a gap equal to the thickness of the coin K will be formed between all of the conveying pieces 384 and the protruding pieces 385. Therefore, the residual detection sensor 386 turns ON when the conveying piece 384 passes through its detection area as shown in Figure 8(c)(d), and also turns ON when the protruding piece 385 passes through its detection area as shown in Figure 8(c)(e).

[0059] Furthermore, as shown in Figure 9(c), when a coin K is caught in an upright position between any of the conveying pieces 384 and the protruding pieces 385, a gap equal to the outer diameter of the coin K will be formed between all of the conveying pieces 384 and the protruding pieces 385. Therefore, the residual detection sensor 386 turns ON when the conveying piece 384 passes through its detection area as shown in Figure 8(d)(f), and also turns ON when the protruding piece 385 passes through its detection area as shown in Figure 8(d)(g).

[0060] In this way, in the coin processing device 10, if coins remain in the lift-up section 38, the lift-up actuator 387 is driven in reverse rotation to create gaps between all of the conveying pieces 384 and the protrusions 385, and the remaining coins can be detected by the remaining detection sensor 386 detecting that the conveying pieces 384 and the protrusions 385 are separated from each other.

[0061] In other words, when the lift-up actuator 387 is driven in reverse rotation, if no gaps occur between all of the conveying pieces 384 and the protrusions 385, there are no coins remaining, and by quickly determining that the machine is empty, the time required for the empty confirmation operation can be shortened.

[0062] Therefore, according to the coin processing device 10, it is possible to reduce the depth dimension and shorten the dispensing time.

[0063] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this and various modifications can be made.

[0064] In the above-described embodiment, the second lift-up conveying belt 382 was arranged on both sides of the first lift-up conveying belt 381, but in the present invention, the second lift-up conveying belt may be arranged on one side of the first lift-up conveying belt.
