The present invention relates to a coin conveying device that separates coins conveyed in an overlapping state into one coin by rotating the separating roller so that the opposite peripheral surface side is opposite to the rotating direction, and more specifically, the above-mentioned conveying belt. The present invention relates to a coin jam removing device that can easily remove coins when they are jammed between the separating roller and the separating roller.

(B) Conventional Technology Conventionally, for example, a coin transport device 31 that supplies change coins in a fixed amount to a change coin discharging device of a vending machine,
As shown in FIG. 3, support shafts 32, 3 are provided on the side wall of the device (not shown).
A conveyor belt 34 that conveys the coin 3 is stretched between the support rollers 33, 33 that support 2 and a separation roller 37 is provided opposite to the conveyor surface 34a of the conveyor belt 34 on the rear stage side that conveys the coin 3. At the same time, the gap h between the separation roller 35 and the conveyor belt 34 is set to an interval that allows one coin 3 to pass through, and is fixed on the support shaft 32 of the support roller 33 at the rear side of the conveyor belt 34. Pulley 36 and pulley 38 fixed on the support shaft 37 of the separation roller 35
The drive belt 41 is stretched between the pulleys 40 of the drive motor 39 arranged in front of the conveyor belt 34.

Then, the drive motor 39 is started to move the conveyor belt 34 to the coin 3
Rotate in the coin transport direction.

At the same time, with respect to the rotation of the transport belt 34 in the coin transport direction,
The coins 3 which are conveyed in the same manner as the separation belt 35 is rotated in the opposite direction and are overlapped by the conveyor belt 34.
By the frictional resistance between the conveyor belt 34 and the separation roller 35, the upper coin 3 is shifted rearward by the separation roller 35 to separate the two-ply stack into one, and the coins 3 are supplied without overlapping the coins 3. Was there.

However, as shown in FIG. 4 (d), when the upper coin 3 is in the state of being overlapped with the first coin in the gap h, the upper coin 3 includes the conveyor belt 34 or the lower coin 3. Since a force in the direction of taking in is applied to the gap h side by the contact between the coins 3, the overlapping resistance of the coins 3 cannot be completely separated by the frictional resistance of the separating roller 35, and the coins 3 are separated. There is a problem in that, when the coins are piled up, the coins are caught in the gap h between the conveyor belt 34 and the separation roller 35, and the operation of the coin conveyor 31 is stopped.

Therefore, as shown in FIG. 4 (e), in order to remove the jam caused by the coin 3, the drive motor 39 is once rotated in the reverse direction and the conveyor belt 34 is rotated in the reverse direction to retract the coin 3. At this time, the separation roller 35 rotates in a direction opposite to the rotation of the conveyor belt 34.

In other words, the conveyor belt 34 applies a force in the direction of removing the coin 3 on the lower side from the gap h, whereas a force is applied in the opposite direction of taking the coin 3 on the upper side into the gap h. In some cases, the coin 3 may move in the direction of easy clogging on the side of the gap h and may be pinched, and the coin 3 cannot be removed from the gap h, and the overlap of two coins cannot be separated. Had.

Further, as shown in FIG. 4F, a support plate 42 is provided on the back surface side of the conveyor belt 34 so that the conveyor bell 34 is not bent by the weight of the coins 3 as shown by a virtual line in the figure. If you have 3 coins
When the paper is caught in the gap h, the conveyor belt 34 cannot contact the support plate 42 and cannot escape downward, and the coin 3 caught in the gap h bites into the conveyor belt 34, and the coin 3 is firmly fixed. It also had the problem of clogging.

(C) Problem to be Solved by the Invention According to the present invention, the power is transmitted to the separating roller via the one-way clutch, the rotation of the separating roller is stopped at the time of reverse rotation of the conveyor belt, and the one-way clutch is clogged with coins. By providing a removal function, the coins sandwiched in the gap between the conveyor belt and the separation roller can be reliably removed by applying only the force in the direction to remove them from the gap, making it easy to remove jams due to overlapping coins. An object is to provide a coin jam removing device that can be removed.

(D) Means for Solving the Problem The present invention is provided with a separation roller formed on the conveying surface of a conveying belt so as to form a gap through which a single coin can pass, and a separating roller is provided in the forward direction for conveying coins. Coins that are conveyed in an overlapping state by rotating the conveyance belt and the separation roller by power transmission by one drive belt so that the peripheral surface side of the separation roller facing the conveyance belt rotates in the opposite direction to the rotation. A device for separating the separation roller, and between the separation roller and the power input section of the separation roller, when the rotation of the conveyor belt is the forward direction, the separation roller is rotated in the reverse direction,
The present invention is characterized in that the coin jam removing device is provided with a one-way clutch for transmitting power in a state in which the separation roller is not rotated when the conveyor belt is rotated in the reverse direction.

(E) Effect of the Invention According to the present invention, since the separating roller is provided with the one-way clutch, when two coins of a normal coin are separated and the coins are conveyed one by one, the coin is separated from the conveyor belt and the separation roller. If the drive belt is reversed and the conveyor belt is reversed when it is caught in the gap, the coin on the lower side is retracted due to frictional resistance with the conveyor belt. At this time, the driving force of the drive belt is not transmitted to the separation roller due to the action of the one-way clutch, the rotation of the separation roller is stopped, and the one-way clutch functions as a coin jam removing means when the drive belt is rotated in the reverse direction. To do.

For this reason, since only the frictional resistance of the conveyor belt that is going to be removed from the gap is applied to the coin, it is possible to remove the coin from the gap and easily remove the clogging due to the overlapping of coins. The operation is simple because the drive belt can be reversed.

At the same time, since the coins can be separated into one coin, the coins can be transported smoothly one by one.

Moreover, since the configuration is only the interposition of the one-way clutch,
The structure is simple.

Further, inside the separation roller 6, a one-way clutch 7 is interposed, and the one-way clutch 7 transmits power in a direction in which the opposing peripheral surface side is opposite to the rotation of the transport belt 5 in the transport direction. By the action of the one-way clutch 7, a coin jam removing device 8 for preventing jamming of the coin 3 is constituted, and the drive motor 9 for rotating the conveyor belt 5 and the separation roller 6 in a predetermined direction is connected to the conveyor belt 5. The coins 3 are arranged on the front side in the conveying direction.

The peripheral surfaces of the conveyor belt 5 and the separation roller 6 are made of a rubber material having a large frictional resistance.

A guide plate 10 for guiding the inserted coins 3 onto the conveyor belt 5 is provided inside the coin insertion portion 4 described above by inclining the coins 3 from the upper part of the coin insertion part 4 to the lower side so that the coins 3 can slide. It is fixed to the inner wall of the charging part 4.

The conveyor belt 5 is mounted on the side walls 2b, 2b of the apparatus main body 2 by the support shaft 1
Support rollers 1 supporting the shafts 11 and 11 and fixed on the shafts 11 and 11.
It is stretched between 2 and 12.

In addition, the rear support shaft 11 that conveys the coins 3 of the supporting time 11,11
Is a shaft supported at a position slightly higher than the shaft support position of the other support shaft 11, and the conveyance belt 5 stretched between the support rollers 12 and 12 is
The coins 3 are provided so as to be inclined upward in the direction in which they are conveyed.

Between the support rollers 12 and 12 described above, the both ends of the side wall 2b of the apparatus body 2 are provided on the back surface of the conveyor belt 5 on the side where the coin 3 is placed.
The upper surface of the support plate 13 fixed to b is brought into contact with the support belt 13 to prevent the conveyor belt 5 from being bent by the weight of the coin 3.

Further, an end portion of the lower portion of the support belt 13 at a position facing the separation roller 6 described later is cut out to form an escape portion 13a below the transport belt 5.

The separating roller 6 is mounted on the support shaft 14 pivotally supported on the side walls 2b, 2b of the apparatus main body 2 via the one-way clutch 7 on the rear-side transfer surface 5a for transferring the coins 3 of the transfer belt 5. ing.

Further, the separation roller 6 sets the gap h with the transport surface 5a of the transport belt 5 to be slightly wider than the thickness of one coin 3 and narrower than the thickness of two coins 3 so that the coin 3 It is provided so that one sheet can pass through.

The one-way clutch 7 is rotated in the direction in which the conveyor belt 5 conveys the coins 3 by the rotation of the drive motor 9 described later, while the rotation of the support shaft 14 rotated by the drive motor 9 causes the separation roller 6 to rotate. And the separation roller 6 is rotated in a direction opposite to the rotation of the conveyor belt 5.

Further, the one-way clutch 7 does not transmit the rotation of the support shaft 14 to the separation roller 6 when the conveyor belt 5 rotates in the reverse direction, and stops the rotation of the separation roller 6.

Then, due to the action of the one-way clutch 7 described above, a force in a direction for removing the coin 3 from the gap h when the transport belt 5 reverses, with respect to the coin 3 sandwiched in the gap h between the transport belt 5 and the separation roller 6. The coin clogging removal device 8 that removes the clogging of the coin 3 by providing only the coin is configured.

The above-mentioned drive motor 9 includes a drive pulley 16 fixed on a rotary shaft 15 of the drive motor 9 and a rear stage side of the conveyor belt 5.
Between the pulley 17 fixed on the support shaft 11 of the support roller 12 and the pulley 18 fixed on the support shaft 14 of the separation roller 6, a drive belt is provided.
When the drive motor 9 is started, the rotation of the drive motor 9 in the forward and reverse directions is driven by the drive belt 19 and each pulley.
The conveyor belt 5 and the separation roller 6 are rotated in the respective predetermined directions via 17, 18.

The operation of the coin transporting device 1 configured as described above is performed by starting the drive motor 9 and rotating the drive motor 9 from the drive shaft 15 via the drive pulley 16, the drive belt 19, and the pulleys 17 and 18. 5, transmitted to the separation roller 6.

Then, the conveyor belt 5 is rotated by the rotation of the drive motor 9 in the conveying direction for supplying the coins 3. At the same time, the separation roller 5
The rotation of the drive motor 9 is rotated from the support shaft 14 via the one-way clutch 7 in a direction opposite to the rotation direction of the conveyor belt 5.

At this time, as shown in FIG. 2B, the coins 3 conveyed by the conveyor belt 5 in the overlapping state are separated from each other by the separating roller 6
The frictional resistance causes the coins 3 on the upper side to be displaced backward and the overlap is separated.

Then, the coins 3 separated into one sheet are conveyed by the conveyor belt 5 and ejected from the ejection port 2a of the apparatus main body 2.

However, if the coin cannot be separated and the coin 3 clasps in the gap h, as shown in FIG. The coin 3 is removed from the gap h.

At this time, the separation roller 6 is stopped by the action of the one-way clutch 7 without transmitting the rotation of the drive motor 9, so that only the force in the direction to be removed from the gap h is applied to the coin 3 and the separation roller 6 is securely operated. Moreover, the coin 3 can be removed from the gap h.

Moreover, as shown in FIG. 2C, the escape portion of the conveyor belt 5 is provided below the conveyor belt 5 facing the separation roller 6.
Since 13a is formed, when the coin 3 is caught in the gap h, the conveyor belt 5 escapes downward, so that the coin 3 comes into full contact with the peripheral surface of the separation roller 6 to increase the frictional resistance. It becomes easy to separate the two coins 3 from overlapping.

As described above, the coin jam removing device 8 is provided inside the separation roller 6 by interposing the one-way clutch 7 that allows the conveyor belt 5 to rotate in the direction opposite to the conveying direction and stops the rotation in the other direction. With this configuration, only the force in the direction of eliminating the coin 3 from the gap h can be applied to the coin 3 sandwiched in the gap h when the conveyor belt 5 reversely rotates, and the clogging of the coin 3 can be reliably removed.

Moreover, by removing the coins 3, the normal coins 3 can be smoothly conveyed one by one.

The structure of the one-way clutch 7 is not limited to the structure shown in the drawings, and another structure may be adopted.
