Description

The present invention relates to a coin feeding device for sorting coins of a plurality of denominations having different diameters one by one and feeding them to the next process.
The present invention also relates to a coin feeding device of a coin processing device that separates coins having different diameters one by one and delivers them to a coin transport device.
The “coin” used in this specification includes currency coins, tokens, medals, and the like, and the shape includes a circle and a polygon.

As a first prior art, it is known that a coin is hooked by a pin fixed on the upper surface of a rotating disk, and coins are divided one by one and delivered to a transport device in the next process (see, for example, Patent Document 1). .
As a second prior art, it is known that coins are received one by one in a fan-shaped concave portion opened on the upper surface side and the peripheral surface side of the rotating disk, and transferred to the transport device in the next process (for example, see Patent Document 2). .

Japanese Patent Laid-Open No. 8-171666 (Figures 1 and 2) Shokai 57-50776 (Figure 4, pages 2-7)

In the first prior art, the division of each coin is only regulated by the pin interval.
Therefore, when the diameter difference between the maximum diameter coin and the minimum diameter coin is large, for example, in British pound, the maximum diameter is 28.5 mm of 2 pound coins and the minimum diameter is 18 mm of 5 pence coins.
Since the pin interval is set in consideration of the allowance allowance, there is a problem that two coins having the smallest diameter enter between the pair of pins and are not separated one by one.
In the second prior art, since the coin is received in the fan-shaped recess, two coins having the smallest diameter do not enter the recess.
However, since gravity is used for delivery of the transport device in the next process, the position of the coin payout port cannot be set freely, and there is a problem that the layout is restricted.

A first object of the present invention is to provide a coin feeding device capable of sorting and feeding coins of a plurality of denominations having large diameter differences one by one.
A second object of the present invention is to provide a coin feeding device in which a coin payout position can be freely set.
A third object of the present invention is to provide a small coin feeding device.

In order to achieve this object, the coin feeding device according to the first aspect of the present invention is configured as follows.
In a coin processing apparatus in which coins are held one by one in a sorting recess arranged on the upper surface of the rotating disk and then sorted one by one, and then transferred to a coin transport device, the sorting recess of the rotating disk is located on the upper surface side of the rotating disk. A fan-shaped opening that is open on the circumferential surface side of the rotating disk, and has a coin pushing part in a part thereof, forming a part of the sorting recess, and A movable body movable in the diameter direction is provided, and the movable body is positioned to the side of the coin pushing portion when receiving a coin, and is moved to the circumferential surface opening side when the coin is delivered to the coin transport device. a coin delivery device of the coin processing apparatus as that.

In this configuration, coins are received in the recesses and are separated one by one.
That is, since only one coin can be positioned, the two smallest diameter coins are not separated and held together.
When the recess moves to the delivery position to the coin transport device, the moving body that forms the recess moves in the diameter direction of the rotating disk.
Because of this movement, the coins held in the recesses are actively moved in the diameter direction of the rotating disk, so that the moving parts can be transferred to the coin transport device.
In other words, since the coin payout position can be controlled by the moving position of the moving body, there is an advantage that the payout position is not restricted.

Further , the concave portion of the rotating disk is a fan shape in which the upper surface side of the rotating disk is opened, and the peripheral surface side of the rotating disk is opened, and has a coin pushing part in a part thereof, the moving body is It is located on the side of the pushing portion when a coin is received, and moves to the circumferential surface opening side when a coin is delivered.

In this configuration, since the concave portion is opened on the upper surface side and the peripheral surface side of the rotating disk, the coin in the storage bowl in which the rotating disk is located is agitated by the rotation of the rotating disk, and only one piece is received in the concave portion.
In other words, the sector-shaped concave portion is partitioned by the edge portion and the retaining ring so that two minimum-diameter coins are not held.
The coin is moved by the concave coin pushing portion.
Then, the moving body moves toward the peripheral opening at a predetermined position, and pushes the coin from the side to the peripheral opening.
The pushed coin is received by the coin transport device and transported to the next process.
Since the pushing portion for pushing the coin is formed on the rotating disk, it can be made of a durable material.
In addition, since the moving body pushes the coin from the side, it does not require a large force and can be miniaturized.
Therefore, there is an advantage that the coin delivery device can be reduced in size.

According to a second aspect of the present invention, in the first aspect of the present invention, the movable body is arcuate, and is attached to the rotating disk so as to be pivotable about one end portion, and a driven body attached to the movable body is provided. It is a coin feeding device of a coin processing device inserted in a groove cam located below the rotating disk.

In this configuration, since the moving body has an arc shape, the circular peripheral edge of the coin is received in the concave portion.
Since the moving body and the driven body move together with the rotating disk, and the driven body is guided by a fixed groove cam, there is an advantage that no special driving device is required.
Further, by appropriately setting the shape of the groove cam, the moving body can be moved in the diameter direction of the rotating disk at a predetermined position, so that the coin held in the recess can be sent out at the predetermined position.
Therefore, the coin delivery device can be reduced in size and is inexpensive.

According to the present invention, a rotating disk whose axis is inclined at a predetermined angle, an upper side and a peripheral surface side are opened on the upward surface of the rotating disk, at least one minimum diameter coin is located, and two minimum diameter coins are not positionable. And a movable body attached to the concave portion of the rotating disk so as to be pivotable, movable to a receiving position for forming the partitioned concave portion, and moved to a moving position moved to the opening side, and attached to the movable body. It is preferable that the coin feeding device includes a driven body and a groove cam which is disposed below the rotating disk and receives the driven body.

In this configuration, in cases other than coin payout, the moving body is positioned at the receiving position, so that the coins are received and held one by one in the sorting recess.
That is, since at least one coin having a minimum diameter is a recess that can be positioned, two minimum coins are not held together.
When the coin is paid out, the moving body moves to the moving position, so that the coin held in the recess is moved in the diameter direction of the rotating disk by the moving body.
By this movement, the coin held in the concave portion is positively moved in the circumferential surface direction of the rotating disk, so that the coin can be sent out from the rotating disk at a predetermined position.
In other words, since the coin payout position can be controlled by the position of the moving body, there is an advantage that the payout position is not restricted.

The present invention, it is preferable that the moving body is the a coin feeding device, characterized in that attached to the pivot shaft arranged on the peripheral edge side of the rotary disk than the moved member.

In this configuration, since the moving body is attached to the pivot shaft disposed on the peripheral side of the rotating disk relative to the driven body, the driven body is positioned on the groove cam on the rear side of the rotating disk.
In other words, since the pivot shaft is moved in advance of the driven body, the driven body is moved by the groove cam in a positional relationship with respect to the pivot shaft.
Therefore, since a large force is not applied to the driven body, there is an advantage that the coin feeding device can be reduced in size and can be made at low cost.

  In a coin feeding device in which coins are held one by one in a sorting concave portion arranged on the upper surface of a rotating disk and in which only one coin having a minimum diameter can be positioned and then sorted one by one, the coin is fed to a coin transport device. A rotating disk tilted at an angle, an upper side and a circumferential surface side of the rotating disk that are open on the upper surface, at least one coin having a minimum diameter and at least two coins having a minimum diameter that cannot be positioned; and the rotating disk A movable body that is pivotally attached so as to form the concave portion and is movable to a receiving position located on a side portion of the sorting concave portion and a moving position moved to the opening side, and a driven attached to the movable body And a groove cam disposed on the lower side of the rotating disk and receiving the driven body, the delivery to the coin transport device A coin delivery device designed to move the movable body in the circumferential direction on.

FIG. 5 is a front view for explaining the operation of the embodiment of the present invention.

This embodiment is a coin feeding device of a coin processing apparatus that processes coins of 8 denominations of 2 pounds, 1 pound, 50 pence, 20 pence, 10 pence, 5 pence, 2 pence and 1 pence, which are British currencies. Device.
In FIG. 1, a coin processing device 100 includes a coin feeding device 102, a coin transport device 104, and a coin sorting device 106.

  That is, the coin delivery device 102 sorts and delivers the coins 110 one by one, passes them to the coin transport device 104, and separates them into denominations by the coin sorting device 106 in the course of transporting a predetermined path by the coin transport device 104. It is a thing.

First, the coin delivery device 102 will be described with reference to FIGS.
The coin sending device 102 has a function of sorting and sending coins of a plurality of denominations one by one.
The coin feeding device 102 includes a rotary disk 112, a recess 114 formed between the protrusions 122, a moving body 116 for moving the coin 110, and a driving body 117 for the moving body.

First, the rotating disk 112 will be described.
The rotating disk 112 has a function of stirring a large number of coins and receiving and sorting the coins 110 one by one in a sorting recess 138 described later.
The rotating disk 112 has a disk shape, and its rotation axis 118 is inclined at a predetermined angle, and has an upward surface 120.

An extrusion disk 126 having six protrusions 122 extending radially on the upward surface 120 and having a recess 114 formed between the protrusions 122 is fixed.
A slightly depressed coin pushing portion 128 is formed on the front surface of the projecting portion 122 in the rotational direction of the rotating disk 112.

On the rear surface in the rotation direction of the protrusion 122, a concave moving body receiving portion 130 is formed, and an arcuate moving body 116 is disposed.
The rotating disk 112 and the extruded disk 126 can be integrally formed of a sintered metal or a wear-resistant resin.

Next, the moving body 116 will be described.
The moving body 116 has a function of moving the coin 110 held in the sorting recess 138 in the diameter direction of the rotary disk 112 at a predetermined position.
Therefore, the moving body 116 can be changed to another structure as long as this function is satisfied.

The moving body 116 is attached to a pivot shaft 134 protruding from the moving body receiving portion 130 on the peripheral side of the rotary disk 112 so as to be pivotable.
This moving body 116 is preferably made of metal or resin in consideration of wear resistance and mechanical strength.

The recess 114 and the inner edge 136 of the moving body 116 constitute a fan-shaped sorting recess 138.
The recess 138 is a flat groove whose upper surface and peripheral surface are open.
The depth of the recess 138, in other words, the thickness of the extruded disk 126 is formed slightly shallower than the thinnest coin thickness among the eight denominations.

This is because two coins are not held together.
In addition, the concave portion 138 is shaped like a fan, and the distance between an inner surface of a retaining ring 140 described later and the innermost portion of the concave portion 138 is set to be not more than twice the diameter of the minimum diameter coin. It is not held side by side.

That is, the circumferential and radial lengths of the recess 138 are less than twice the minimum diameter coin.
When the moving body 116 is located at the receiving portion 130, it is located at the receiving position RP.
The rotating disk 112 is disposed at the bottom of a cylinder-shaped retaining ring 140 for retaining coins.

An opening 142 is provided in the transfer portion of the holding ring 140 to the transfer device 104 so that the coin 110 can pass therethrough.
A retaining bowl 144 is further attached to the retaining ring 140, and a retaining part 146 is provided so as to face the rotating disk 112.
Accordingly, the coin 110 inserted into the holding unit 146 is guided toward the rotating disk 112.

Next, the driving device 117 for the moving body 116 will be described.
The driving device 117 has a function of moving the moving body 116 from the receiving position RP to the moving position MP at a predetermined position.
Therefore, the drive device 117 can be changed to a structure other than the embodiment as long as this function is satisfied.
The driving device 117 includes a driven body 154 and a cam 157.

First, the driven body 154 will be described.
An arc-shaped through hole 148 is formed around the pivot shaft 134 in the rotary disk 112, and a pin 150 fixed in the middle of the moving body 116 passes through the through hole 148 . A roller 152 is rotatably attached to the lower end of the pin 150.
This roller 152 is a driven body 154.

Next, the cam 157 will be described.
The driven body 154 is movably inserted into a groove cam 158 formed on the upper surface of an inward flange 156 formed in a ring shape from the inner peripheral surface of the retaining ring 140 toward the center.

  The groove cam 158 includes a circular receiving groove 160 centered on the rotation center of the rotary disk 112, a moving groove 162 that has a larger diameter than the receiving groove 160 and holds the moving body 116 at the moving position MP, and the receiving groove 160. A feed process groove 164 and a return process groove 166 returning from the movement groove 162 to the receiving groove 160 are formed.

Therefore, when the driven body 154 is positioned in the receiving groove 160, the moving body 116 is held by the receiving portion 130 and is in the receiving position RP.
Accordingly, the moving body 116 forms a sector-shaped partitioning recess 138 together with the recess 114.
As shown in FIG. 5, the sorting recess 138 is such that the bottom B closest to the rotation shaft 180 (in the embodiment, the tip of the moving body 116) is slightly separated from the inner surface of the retaining ring 140 than the diameter of the maximum diameter coin 110L. positioned.

Further, this distance is less than twice the diameter of the smallest coin 110S.
Accordingly, the sorting concave portion 138, in other words, the smallest diameter coin 110S is not received side by side in the diameter direction of the rotating disk 112 between the retaining ring 140 and the bottom portion B.

Further, since the sorting recess 138 has a fan shape, two coins 110S having the smallest diameter are not received side by side in the circumferential direction of the rotary disk 112.
When the driven body 154 is positioned in the feeding process groove 164, the moving body 116 is pivoted clockwise with the pivot shaft 134 as a fulcrum.

When the driven body 154 is positioned in the moving groove 162, the moving body 116 moves to the moving position MP.
Thereafter, since the driven body 154 is positioned in the return process groove 166, the driven body 154 is rotated counterclockwise about the pivot shaft 134 and returned to the receiving position RP.

  Therefore, the cam 157 is not limited to the groove cam 158, but when the groove cam 158 is used, an auxiliary device for moving the driven body 154 along the cam 157 is unnecessary, so the structure is simplified and the size can be reduced. And has the advantage of being inexpensive.

Next, the coin transport device 104 will be described.
The coin transport device 104 has a function of receiving coins 110 sent one by one from the coin delivery device 102 and transporting them to a predetermined coin processing device, for example, a coin sorting device.
The coin transport device 104 includes an endless traveling body 163 and pins 167 attached to the endless traveling body 163 at a predetermined interval.

The endless progress body 163 is a loop body that can be bent, and is a chain 169 having a predetermined length in this embodiment.
However, the endless progression member 163 can be changed to a belt.
The endless progression member 163 is guided by a plurality of sprockets and circulates in an L-shaped loop path.

  That is, the path of the endless traveling body 163 approaches the top of the rotating disk 112 most in the lowermost sprocket 168, then proceeds upward at a steep angle, and then proceeds through the first sorting unit 170 with a gentle climbing slope, Next, after proceeding substantially vertically, the second sorter 172 having a gradual climbing inclination located above the first sorter 170 is advanced and then returned to the sprocket 168.

The pins 167 are fixed to the side surface of the endless traveling body 163 at a predetermined interval so as to hook the coins 110 fed from the coin feeding device 102 one by one.
Accordingly, the sprocket 168 and the rotating disk 112 rotate in conjunction with each other.

That is, the gear 174 to which the sprocket 168 is fixed meshes with the gear 176 disposed below the rotary disk 112.
In other words, the gear 176 is rotatably attached to the shaft 180 fixed to the base 178, and the rotating disk 112 is fixed to the gear 176.
The gear 174 meshes with the side gear 182 and the gear 182 is driven by an electric motor (not shown) at a predetermined speed.

Therefore, the rotating disk 112 and the sprocket 168 rotate and move at a predetermined speed ratio.
In other words, the sorting recess 138 and the pin 167 move correspondingly.
A notch 181 is formed on the outer periphery of the protrusion 122 of the rotating disk 112 so that the coin 110 is smoothly transferred from the moving body 116 to the pin 167 , and the pin 167 can enter the notch 181. .

A plate-shaped first coin guide 182 is disposed along the endless traveling body 163 in the vicinity of the sprocket 168, a second coin guide 184 is disposed along the first sorting section 170, and a third along the second sorting section 172. A coin guide 186 is arranged.
Therefore, the coin 110 hooked to the pin 167 is moved to a predetermined position by the endless progress member 163 while being guided by the coin guides 182, 184, and 186.

Next, the operation of this embodiment will be described with reference to FIG.
When the coin 110 is inserted into the holding unit 146, it is moved to the rotating disk 112 side by the inclination of the bowl 144, and comes into contact with the rotating disk 112 and the pushing disk 126.
The rotating disk 112 is automatically or constantly rotated upon detection of coin insertion.

As the rotating disk 112 rotates, the coin 110 is agitated by the protrusion 122 and enters the sorting recess 138.
At a position other than the vicinity of the coin transport device 104, the moving body 116 is located at the receiving portion 130, and thus is at the receiving position RP.
In other words, the recess 138 has a fan shape.

Therefore, only one coin 110 is held in the partitioning recess 138 defined by the pushing portion 128 of the protrusion 122 and the arcuate surface of the moving body 116.
That is, since the outer periphery of the coin 110 is guided by the retaining ring 140, only one maximum diameter coin 110 is held in the recess 138 formed slightly deeper than the diameter of the maximum diameter coin 110L.

Further, since the depth is less than twice the diameter of the minimum diameter coin 110S, two minimum diameter coins 110S cannot enter the diameter direction of the rotating disk 112.
Furthermore, since the recess 138 is fan-shaped, the two smallest diameter coins 110S cannot be arranged in the circumferential direction of the rotary disk 112.

Accordingly, only one minimum diameter coin 110S is held in the sorting recess 138.
The coin 110 held in the sorting recess 138 is moved to the coin transport device 104 side by the rotation of the rotary disk 112.
In other words, the coin 110 is moved from below to above.

At this time, the coin 110 is pushed and moved by the pushing portion 128 and almost no force is applied to the moving body 116.
When the moving body 116 moves to the vicinity of the coin transport body 104, the driven body 154 moves through the feeding process unit 164, so that the driven body 154 is moved in the diameter direction of the rotary disk 112.

As a result, the movable body 116 is pivoted clockwise about the pivot shaft 134 as a fulcrum.
Therefore, the moving body 116 pushes the coin 110 located in the sorting recess 138 in the diameter direction of the rotary disk 112 from the side, so that the coin 110 is pushed out from the sorting recess 138.

When the driven body 154 is positioned in the moving groove 162, the moving body 116 is moved to the moving position MP, so that the coin 110 passes through the opening 142 and is pushed out to the moving path of the pin 167 .
Immediately after being pushed out, the coin 110 is pushed by the pin 167 and conveyed to the next step while being guided by the first coin guide 182, the second coin guide 184, the third coin guide 186, and the like.

The present invention can be used for a coin feeding device that moves a coin to a predetermined position at a predetermined position.
Therefore, in the above embodiment, the coin is used to be transferred to the coin transport device. However, the present invention can also be applied to a so-called coin hopper, which is a coin feeding device that pays out coins one by one at a predetermined position.
