Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a coin sorting device for sorting a plurality of types of coins having different diameters.

[Conventional technology]

Conventionally, as disclosed in, for example, Japanese Patent Laid-Open No. 55-28113, a rotary disc located below a coin slot and rotating in a fixed direction, and a coin delivery port opening in a part of a wall surrounding the rotary disc. There is also known a coin sorting device which is provided with a coin sorting passage arranged outside the rotating disk and in which a plurality of coin-type coin drop openings are arranged in the coin sorting passage. In this device, an enclosure wall is arranged above the vicinity of the periphery of the rotating disk so that coins inserted therein can be delivered from a coin delivery port, and an outer periphery of the rotating disk projecting around the enclosure wall, A guide plate and a rail arranged on the outer side thereof form a coin sorting passage along the circumferential direction, and coins delivered from the coin delivery port straddle the outer peripheral portion of the rotating disc and the rail. The coins fall by coin type (diameter) into the coin outlets of different widths that are arranged between the outer periphery of the rotating disc and the rails while being transferred by rotating the rotating disc. Has become.

[Problems to be solved by the device]

According to the above device, since the coins are transferred in the coin sorting passage while slightly riding on the outer peripheral portion of the rotating disk, the rotating force of the rotating disk is not sufficiently applied to the coins, and therefore the coins slip and the coins are transferred. As the ability decreases, the coin transfer speed varies, causing a collision between coins,
There is a problem that the selection of coins becomes uncertain due to pressure contact.

Therefore, the applicant of the present invention, outside the rotating disk,
A coin sorting passage having a coin support surface in which a plurality of coin-type coin drop ports are arranged and a guide wall projecting upward from the outer periphery thereof is formed in the circumferential direction, and the coin sorting surface is provided above the coin support surface. I applied for a device that installed a coin sorting transfer member that moves coins in the direction along the guide wall while coming into contact with coins fed into the passage from above, and that reliably transfers coins with this member. It is (actual Kaisho 63
-293090). In the case of such a device, in order to be able to send coins from the coin outlet to the coin sorting passage with a simple structure, the coin outlet is provided between the coin outlet and the coin sorting passage. It is desirable to install a coin delivery means for placing the coins delivered from the delivery belt on the delivery belt and sending the coins into the coin processing passage.

By the way, in such a device, in order for a coin to drop into a drop port according to a denomination, it is required that the coin moves along the guide wall in the coin sorting passage. When coins are fed into the coin sorting passage by the belt, before they reach the guide wall,
Since the coin sorting transfer member moves the coin sorting passage downstream and shifts from the delivery belt, the delivery belt alone is not sufficient to feed coins to the position along the guide wall. It should be noted that while coins move through the coin sorting passage, centrifugal force or the like acts toward the guide wall side, but it is desirable to more positively follow the coins along the guide wall in the initial stage of the movement. .

Further, in order to prevent a situation in which coins are stuck to each other and are prevented from falling in the coin sorting passage, it is required that each coin move at an appropriate interval. Since there are cases where they are close to each other, it is desirable to take measures to keep the distance between coins.

In view of the above circumstances, the present invention provides a coin sorting transfer member that moves a coin while coming into contact with the coin fed into the coin sorting passage from above, and a coin delivered from the coin delivery port on a delivery belt. An object of the present invention is to provide a coin sorting device capable of efficiently sorting coins by means of a coin delivery means or the like for feeding the coins into the coin sorting passage, and more particularly, to enhance the certainty of coin sorting. To do.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention has a rotary disc located below a coin slot and rotating in a certain direction, a coin outlet opening in a part of a wall surrounding the rotary disc, and a coin. A coin sorting passage having a supporting surface and a guide wall projecting upward from the coin supporting surface and arranged outside the rotary disc; In the coin sorting device arranged in the direction along the guide wall, above the coin supporting surface of the coin sorting passage, while guiding the coins from above while contacting the coin fed into the coin sorting passage from above. While installing a coin sorting transfer member that moves in the direction along the wall,
Between the coin outlet and the coin sorting passage, while laying a coin delivery means for placing the coin delivered from the coin outlet on the delivery belt and sending it to the coin sorting passage, the coin support surface A feed roller for feeding coins toward the guide wall is provided in the vicinity of the delivery belt and on the downstream side of the delivery belt.

Further, in this configuration, the peripheral speeds of the feed belt and the feed roller are set to be lower than the coin transfer speed of the coin sorting transfer member.

[Action]

According to the above configuration, the coins ejected from the coin delivery port are placed on the delivery belt and carried to the coin sorting passage, and then transferred to the coin sorting passage by the coin sorting transfer member. At this time, the coin is positively moved along the guide wall by the feeding action of the feed roller.

Further, if the peripheral speeds of the delivery belt and the feed roller are set to be lower than the coin transfer speed of the coin sorting transfer member, the speed is increased when the coins sequentially sent by the coin sending means move to the coin sorting passage. , The intervals between coins will be widened.

The power of the motor 5 is also transmitted to the drive shaft 407 of the drive-side pulley 405 around which the motor 5 is wound via a transmission mechanism (not shown). Then, for each of the peripheral velocities v ₁ , v ₂ , v ₃ , the above relationship (v ₁ = v ₂
In order to obtain <v ₃ ), the speed ratio is set in each power transmission system for the rotating member 20 and the drive pulley 405.

According to the structure as described above, a large number of coins 100 of a plurality of types having different diameters are put into the rotating disc 2 and the motor 5 is driven, whereby the coin 100 is centrifugally generated by the rotation of the rotating disc 2. The coins are sent out one by one from the coin delivery port 8 to the coin delivery passage 13 and enter between the delivery belt 401 of the coin delivery means 40 and the coin splash-prevention plate 402, and are placed on the delivery belt 401 to be used by the delivery belt 401 It is transported to the sorting passage 10.

The coin 100 conveyed to the coin sorting passage 10 has a coin supporting surface 1
It is inserted between 1 and the tip portion 22a of the lip member 22 of the rotary member 20, and is transported by the lip member 22 in the coin sorting passage 10 in the circumferential direction. At this time, as shown in FIG. 5, before the coin 100 carried by the delivery belt 401 reaches the guide wall 12 on the outer periphery of the coin sorting passage 10, the coin 100 is moved in the circumferential direction by the lip member 22 to be delivered belt. Although it deviates from 401, since the feed roller 41 is provided on the downstream side, the coin 100 moves in the circumferential direction (arrow B) in the range where the feed roller 41 is arranged, and the guide wall 41 moves. It is sent in the direction toward 12 (arrow C). Thus, at the initial stage of transfer in the coin sorting passage 10, the coin 100 is positively moved along the guide wall 12.

Further, since the peripheral speeds v ₁ and v _{2 of the} delivery belt 401 and the feed roller 41 are lower than the peripheral speed of the lip member v ₃ , a large number of coins 100 are sequentially selected from the coin delivery passage 13 for coin selection. Even when the coins 100 are in close contact with each other in the coin delivery passage 13 when the coins are fed into the passage 10, the speed is increased in the coin sorting passage 10 so that the coins can be reliably separated from each other.

The coin 100 moved to the coin sorting passage 10 is rotated by the rotating member 20.
The guide member 12 and the coin support surface 11 by the lip member 22 of
It moves in the circumferential direction while being pressed against. In this way, while the coin 100 moves along the guide wall 12,
Various coins 100 having different diameters fall into the coin drop ports 15a to 15b corresponding to the coins 100 and are classified. In this case, a coin 10
If 0 shifts toward the inside of the passage, the coin 100 may fall to a drop port other than the corresponding drop port, so that the coin 100 must be properly aligned with the guide wall 12 to prevent misselection. In response to such a request, the action of causing the coin 100 to follow the guide wall 12 can be obtained by the centrifugal force during movement and the lip member 22. In particular, the feed roller in the initial stage of transfer in the coin sorting passage 10. The feeding action of 41 ensures that the coin 100 is guided along the guide wall 12. In addition, by setting the peripheral speeds v ₁ , v ₂ , and v ₃ as described above so that the coins 100 in the coin sorting passage 10 are spaced from each other, the coins stick to each other and are prevented from falling into the drop port. Is also prevented.

[Effect of device]

As described above, according to the present invention, the coins fed into the coin sorting passage are transferred by the coin sorting transfer member that comes into contact with the coins from above, so that sufficient coin transfer capability can be obtained. The coin transfer speed in the sorting passage can be increased to improve the efficiency of the sorting process. Further, by providing the coin sending means for sending the coin on the sending bell, between the coin sending outlet and the coin sorting passage,
With a simple structure, coins can be fed from the coin outlet to the coin sorting passage. Furthermore, in particular, at a position downstream of the coin supporting surface in the vicinity of the delivery belt,
Since the feed roller for feeding the coins toward the guide wall is provided, the coins fed into the coin sorting passage can be reliably guided along the guide wall, which can enhance the certainty of coin sorting. .

Further, if the peripheral speeds of the delivery belt and the feed roller are set to be lower than the coin transfer speed of the coin sorting transfer member, the intervals between the coins sequentially fed from the coin delivery means move to the coin sorting passage. Since the coins do not stick to each other in the coin sorting passage, the certainty of coin sorting can be further enhanced.
