Japanese Unexamined Patent Publication No. 2019-185509

In the above-mentioned coin storage, since the storage unit is configured as a unit with the storage unit of other denominations, each denomination (for example, 1-yen coin, 50-yen coin, 5-yen coin, 100-yen coin, etc. The storage area for 10-yen coins and 500-yen coins) is divided into one unit as a whole, which has the following problems.

That is, in a change machine to which a coin storage is applied, for example, when a specific denomination such as a 1-yen coin is not handled, or when a specific denomination such as a 10-yen coin is desired to be stored. Conceivable.

However, in the above-mentioned coin storage, one unit is configured with the storage area of each denomination divided. Therefore, when a specific denomination such as a 1-yen coin is not handled, 1 yen is used. The coin storage area becomes a dead space, which may lead to a decrease in storage efficiency. In addition, since one unit is configured with the storage area of each denomination divided, it is not possible to increase only the storage area of a specific denomination such as a 10-yen coin, and flexible operation is possible. It was difficult to plan.

In view of the above circumstances, it is an object of the present invention to provide a coin storage capable of flexible operation and improvement of storage efficiency.

In order to achieve the above object, the coin storage according to the present invention is stored in a storage unit for storing coins that have been deposited and sorted by denomination, and in the storage unit when driven in response to a withdrawal command. A coin provided with a payout unit that pays out coins one by one, and a payout unit that pays out a predetermined number of coins to a withdrawal transport unit on the downstream side while determining the authenticity of the coins paid out by the payout unit. The storage is characterized by having the storage unit, the payout unit, and the payout unit, and having a storage unit unitized for each denomination.

Further, according to the present invention, in the coin storage, the storage unit includes a unit body for accommodating the storage unit, the payout unit, and the payout unit, and the unit body is a unit body constituting another storage unit. It is characterized by being configured to be connectable.

According to the present invention, since the storage unit has a storage unit, a payout unit, and a payout unit and is configured as a unit for each denomination, it is possible to configure only the storage unit of the required denomination. can. That is, when a specific denomination such as a 1-yen coin is not handled, it is possible to prevent the formation of a dead space by eliminating the storage unit of the specific denomination, and for example, 10 yen. If it is desired to increase the number of storage units of a specific denomination such as coins, it can be achieved by increasing the number of storage units of the specific denomination. This has the effect of enabling flexible operation and improving storage efficiency.

Further, by driving the feeding motor 75, the feeding pulley 71 on the left side of all the storage units 34 rotates clockwise when viewed from the front. By rotating the feeding pulley 71 on the left side in this way, the feeding belt 73 is displaced to the right while the extending portion between the lower pulleys is displaced to the left.

By the way, in the storage unit 34 that does not store coins of the corresponding denomination, as shown in FIG. 11, the payout motor 65 is not driven. Therefore, the coins stored in the storage unit 50 are carried out to the left due to the displacement of the carry-out belt 53, but the payout belt 63 does not move and stays in the storage unit 50.

On the other hand, in the storage unit 34 for storing coins of the corresponding denomination, the payout motor 65 is driven as shown in FIG. By driving the payout motor 65 in this way, the payout pulley 61 on the left side rotates counterclockwise when viewed from the front. As the payout pulley 61 on the left side rotates counterclockwise when viewed from the front, the payout belt 63 has the extension portion between the upper pulleys displaced to the left and the extension portion between the lower pulleys to the right. Displace towards you.

As a result, the coins carried out toward the left side by the carry-out belt 53 are sent toward the left side due to the displacement of the payout belt 63, but on the way, the extending portion between the upper pulleys of the payout belt 63 by the reverse roller 66. The coins are restricted from overlapping with each other, and the coins are paid out one by one by the guide member 67 on the extending portion between the upper pulleys of the payout belt 63.

The coins paid out one by one from the payout unit 60 in this way pass through the payout path 43a due to the displacement of the payout belt 73 and are paid out to the withdrawal transport unit 14. The authenticity and number of coins passing through the feeding path 43a are detected by the feeding detection unit 76, and when the feeding detecting unit 76 detects that a predetermined number of coins have been paid out, the control unit 20 controls the feeding motor 55. A command is given to the payout motor 75 to stop the drive, and a command is given to the payout motor 65 being driven to stop the drive.

As a result, the coin storage 30 can pay out a predetermined number of corresponding coins to the withdrawal transport unit 14 according to the withdrawal command.

As described above, according to the coin storage 30 according to the embodiment of the present invention, the storage unit 34 has a storage unit 50, a payout unit 60, and a payout unit 70, and is configured as a unit for each denomination. Therefore, it can be composed of only the storage unit 34 of the denomination required according to the operation of the applied coin processing device 1. That is, when the coin processing device 1 does not handle a specific denomination such as a 1-yen coin, the storage unit 34 of the specific denomination can be eliminated to prevent the formation of a dead space. If the coin processing device 1 wants to increase the number of storage units of a specific denomination such as a 10-yen coin, it can be achieved by increasing the number of storage units 34 of the specific denomination. .. This enables flexible operation and improves storage efficiency.

According to the coin storage 30, the storage unit 34 unitized for each denomination is composed of a carry-out belt 53 stretched endlessly with respect to the unit main body 40, and coins are placed on the carry-out belt 53. It is composed of a storage unit 50 that stores in a stacked state and a payout belt 63 that is endlessly stretched on the downstream side of the carry-out belt 53 in the carry-out direction in the unit body 40, and the payout belt 63 is displaced according to a withdrawal command. In this case, it is composed of a payout unit 60 that pays out coins stored in the storage part 50 one by one, and a payout belt 73 that is endlessly stretched on the downstream side of the payout belt 63 in the payout direction in the unit main body 40. Since it is provided with a payout unit 70 for feeding out a predetermined number of coins to the withdrawal transport unit 14 on the downstream side while determining the authenticity of the coins paid out due to the displacement of the belt 63, it corresponds to the coins to be stored. The belts 53 and the like may be arranged on the unit main body 40 according to the dimensions. Then, the coin storage 30 can be configured only by arranging such storage units 34 in parallel, and the assembly work can be facilitated.

According to the coin storage 30, the transmission rod 54 penetrates the shaft hole 51a of the left side carry-out pulley 51 in all the storage units 34 arranged side by side in the front-rear direction, and is driven by the carry-out motor 55. Since the carry-out pulley 51 on the left side is rotated around the central axis, the drive source can be shared, and the increase in manufacturing cost can be suppressed by reducing the number of parts. Moreover, since the transmission rod 54 is penetrated without connecting the left-side carry-out pulleys 51 to each other, the driving force of the carry-out motor 55 can be efficiently transmitted to each carry-out pulley 51, and coins are stacked. The carry-out belt 53 can be satisfactorily displaced even in the storage portion 50 that is stored in the closed state.

According to the coin storage 30, the left feeding pulley 71 constituting each storage unit 34 is connected to the left feeding pulley 71 in the other storage units 34, and therefore all the coins are stored by driving the feeding motor 75. The feeding belt 73 can be displaced by rotating the feeding pulley 71 on the left side of the unit 34. As a result, the drive source can be shared, and the increase in manufacturing cost can be suppressed by reducing the number of parts.

In the coin storage 30, the unit body 40 is configured as follows.

As shown in FIG. 13, the unit main body 40 has a curved portion 44 formed on the upper side of the carry-out pulley 52 on the right side. The curved portion 44 constitutes the right end portion of the storage portion 50, and a stepped wall 44a is formed downward. The stepped wall 44a formed in the central portion of the curved portion 44 in the front-rear direction has a lower end portion close to the carry-out belt 53, and the gap with the carry-out belt 53 is smaller than the thickness of the coin. It is said to be.

On the other hand, conventionally, it is known that a plurality of ribs are provided so as to be close to the carry-out belt in the region constituting the right end portion of the storage portion. However, if the ribs are deformed due to wear or the like, coins may enter between the ribs or between the ribs and the carry-out belt, which is not preferable.

In that respect, since the stepped wall 44a is formed in the curved portion, there is no possibility of deformation due to wear or the like, and it is possible to prevent coins from entering between the curved portion 44 and the carry-out belt 53. can.

As shown in FIG. 14, the base portion 45 on which the extension portion between the upper pulleys of the carry-out belt 53 in the unit main body 40 is placed has a plurality of lengths (two in the illustrated example) extending along the left-right direction. A scale rib 45a is formed.

Such a long rib 45a has the following dimensions. As shown in FIG. 15, the separation distance between the long rib 45a on the rear side and the rear end portion of the carry-out belt 53 is L1, and the long rib 45a on the rear side and the long rib 45a on the front side The separation distance is L2, the separation distance between the long rib 45a on the front side and the front end portion of the carry-out belt 53 is L3, and these L1 to L3 are the outer diameters of the coins on which the carry-out belt 53 is laminated. Is smaller than.

As a result, the coin placed on the extending portion between the upper pulleys of the carry-out belt 53 is placed in the upper region of any of the long ribs 45a, and when the carry-out belt 53 is displaced, the coin is placed on the base portion 45. Deformation such as wear due to sliding contact can be suppressed, and durability can be improved.

As shown in FIGS. 16 and 17, in the unit main body 40, the rear side of the storage portion 50 in the rear main body wall portion 42 with respect to the storage portion corresponding portion 411 which is the front side of the storage portion 50 in the front main body wall portion 41. The storage portion corresponding portion 421 is formed so as to protrude upward. As a result, as shown in FIG. 15, the storage portion corresponding portion 421 of the rear main body wall portion 42 corresponds to the storage portion of the rear main body wall portion 42 of the other unit main body 40 which is on the rear side of the unit main body 40. It can face the front surface of the portion 421, and defines the front-rear dimensions of the storage portion corresponding portion 421 and the storage portion 50.

Two long convex portions 421a are formed on the front surface and the rear surface of the storage portion corresponding portion 421 of the rear side main body wall portion 42 in a manner parallel to the extending portion between the upper pulleys of the carry-out belt 53. There is. The separation distance between these two long convex portions 421a is smaller than the outer diameter of the coin having the smallest outer diameter (for example, a 1-yen coin).

As described above, the long convex portion 421a is formed on the front surface and the rear surface of the storage portion corresponding portion 421 of the rear side main body wall portion 42, so that the coins stored in the state of being stacked on the storage portion 50 are in an upright posture. When it comes into contact with the front surface or the rear surface of the storage portion corresponding portion 421, it can be prevented from sticking to the front surface or the rear surface of the storage portion corresponding portion 421 due to surface tension or the like.

Moreover, the front and rear dimensions of the storage portion 50 can be defined on the front surface and the rear surface of the storage portion corresponding portion 421 of the rear side main body wall portion 42, and the volume of the storage portion 50 can be increased.

As shown in FIGS. 18 and 19, in the unit main body 40, the front side portion 461 and the rear side portion 462 of the upper pulley extending portion of the payout belt 63 constituting the payout belt 60 are larger than the front and rear dimensions of the carry-out belt 53. The diameter is also increased, and the front-rear dimensions are gradually reduced toward the downstream side in the payout direction. Further, the front side portion 461 and the rear side portion 462 form a plane substantially the same as the extending portion between the upper pulleys.

On the other hand, conventionally, it is known that the front side portion and the rear side portion become inclined portions that gradually incline upward as they are separated from the payout belt. In this case, even if the payout belt is displaced, the coins hung on the inclined portion continue to rotate and cannot be paid out, and as a result, there is a risk that the coins will stay.

In that respect, in the unit main body 40, the front side portion 461 and the rear side portion 462 have a larger diameter than the front-rear dimension of the carry-out belt 53, so that coins carried out from the carry-out belt 53 can be smoothly received. .. Moreover, the front side portion 461 and the rear side portion 462 form a plane substantially the same as the extending portion between the upper pulleys of the payout belt 63 while being configured so that the front-rear direction gradually becomes smaller toward the downstream side in the payout direction. Therefore, as shown in FIG. 20, the coin can be paid out toward the payout portion 70 without being twisted and rotated.

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.

In the above-described embodiment, the unit bodies 40 are connected to each other and the storage units 34 are arranged side by side, but in the present invention, the unit bodies are engaged with each other by using an engaging means to engage the storage units. May be arranged side by side.
