In the configuration of this coin feeding device, a transport surface that is suspended by rollers 1 and 2 that are supported by a body (not shown) and that transports coins in the feeding direction f
The transport belt 4 includes a transport belt 4 whose lower surface is supported and guided by a guide 3 and a separation roller 5 rotatably supported above the transport belt 4 on the side of the feeding direction f. The coins are arranged at an interval that allows only one coin to pass in the thickness direction of the coin with respect to the conveying surface 4a of the conveying belt 4 so that the coins are in a single layer state. Then, the coins placed on the transport belt 4 in a non-aligned state are fed out in a single layer state by the separation roller 5 while being transported by the transport belt 4 in the feeding direction f.

In such a coin feeding device, FIG.
As shown in (b), depending on how the conveyed coins c overlap, the coin c may be located between the separation roller 5 and the conveyance belt 4.
May be jammed and coin jams may occur. In such a case, the conveying surface 4a of the conveying belt 4 is reversed in the direction opposite to the coin feeding direction f,
Eliminates jams in coins.

The interval between the side walls 26 on both sides is wider than the diameter of the largest diameter coin among the coins to be processed, and narrower than two diameters of the smallest diameter coin, so that the coins are aligned in the dispensing direction F. Is formed.

As shown in FIG. 1, the conveying roller 22 on the upstream side in the feeding direction F (opposite side to the feeding direction F) is formed with a small diameter on the driven side, and the conveying roller 23 on the downstream side in the feeding direction F is driven on the driving side. It is formed with a large diameter. The belt portion on the upper surface facing the hopper 21 of the transport belt 24 suspended by the transport rollers 22 and 23 is configured as a transport surface 27 on which coins are loaded and transported. The transport surface 27 is arranged so as to be inclined upward in the feeding direction F.

When pressed downward together with the transfer surface 27, an elastic force is generated such that the stopper 34 at the other end returns to the upper initial position with the fixed portion 33 at one end as a fulcrum.

On the lower surface of the fixed guide 28, a restricting member 35 for defining a lower limit position of the stopper portion 34 of the movable guide 29 is attached. The coins smaller than two coins of the minimum thickness coin can be separated by two or more coins.
Do not pass under the.

The separation roller 25 is provided at an interval at which coins can pass in a single-layer state with respect to the upper surface of the transport surface 27 of the transport belt 24, that is, a maximum of coins to be processed, in order to make the fed coins into a single-layer state. The coins are arranged with an interval larger than the thickness of the thick coin and smaller than the thickness of two coins of the minimum thickness.

As shown in FIG. 5, pulleys 36 and 37 are coaxially fixed to the transport roller 23 and the separation roller 25 on the driving side, respectively. The pulleys 36 and 37 are rotated by a motor 38 as a driving means. A drive transmission belt 40 is suspended between the pulley 39 and the pulley 39. The forward and reverse rotation of the motor 38 causes the transport surface 27 of the transport belt 24 to move in the feeding direction F.
And it is moved in a reverse rotation direction opposite to the feeding direction F.
A one-way clutch is interposed in the separation roller 25, and when the transport surface 27 of the transport belt 24 moves in the feed direction F by forward rotation of the motor 38, the transport roller 27 rotates in a direction opposite to the feed direction F of the transport surface 27, The conveyor belt 24 is rotated by the reverse rotation of the motor 38.
Is configured not to rotate when is moved in the reverse direction.

Next, the operation of the coin feeding device 14 will be described.

The coin is transported from the hopper 21 to the transport surface of the transport belt 24.
Among the coins that have been inserted and fallen on the transport surface 27 among the inserted coins, the coins are aligned in the line-out direction F by the side walls 26 on both sides.

By the forward rotation of the motor 38, the transport belt 24 is rotated so that the transport surface 27 of the transport belt 24 moves in the feeding direction F, and the separation roller 25 is moved in a direction opposite to the direction in which the transport surface 27 of the transport belt 24 moves. Is rotated.

The coins that are in surface contact with the transport surface 27 of the transport belt 24 move in the feeding direction F together with the transport surface 27 and
The coins passing over the coins in a single-layer state and overlapping the coins that are in surface contact with the transport surface 27 are regulated by the separation roller 25.

For example, as shown in FIGS. 2 (a) to 2 (d), a state in which another coin C2 is placed on a coin C1 which is in surface contact with the conveying surface 27 of the conveying belt 24, and the two sheets overlap. With separation roller 25
The coin C2 on the upper side
, And is returned to the inside of the hopper 21, and only the lower coin C1 enters below the separation roller 25 and passes in a single-layer state. By passing the lower coin C1, the upper coin C2 is transferred to the transport surface.
It is dropped to 27 and subsequently passed under the separation roller 25 to be fed out.

Accordingly, the coins are arranged in a single line by the side walls 26 on both sides, the coins are arranged in a single layer by the conveyor belt 24 and the separation roller 25, and the coins are unreeled from the coin feeding device 13 in a single layer and a single line. It is.

Further, as shown in FIG.
The leading end of the upstream coin C4 enters under the downstream coin C3, and the downstream coin C3 is placed on both the transport surface 27 and the upstream coin C4, and the separation roller 25 is overlapped in a wedge shape.
The coin C3 on the downstream side
25, but cannot be returned to the hopper side because the coin C3 is placed on both the transport surface 27 and the coin C4 on the upstream side, and as shown in FIG. 3 (b), the coins C3, C4 It is easy to enter under the separation roller 25 with the overlapping.

When the coins C3 and C4 enter under the separation roller 25 in a state where they are overlapped, as shown in FIG. 3C, the leading ends of the coins C3 and C4 are pressed downward by the separation roller 25, and The movable guide 29 that supports and guides the transport surface 27 of the transport belt 24 is pushed down from its initial position against elasticity, and the coins C3 and C4 and the transport surface 27 sink into the opening 31.
As a result, the upper coin C3 is transferred to the transfer surface 27 of the transfer belt 24.
From the lower coin C4 and the separation roller 25, and is slid on the lower coin C4 by the reverse rotation force of the separation roller 25 to move the hopper 21 in the direction opposite to the feeding direction F. It is flipped inside.

When the coins cannot be separated and the coins are jammed under the separation roller 25, the conveyed belt 24 is reversed so that the jammed coins come off from under the separation roller 25, and the coins are jammed. Is eliminated. After the coin jam is cleared, the normal rotation of the transport belt 24 is restarted.

When the transport belt 24 rotates in the reverse direction, the lower surface of the transport surface 27 of the transport belt 24 pressed down by the opening 31 is supported and guided by the movable guide 29. 27 is prevented from being rubbed at the edge of the opening 31, and damage to the transport belt 24 can be prevented.

As described above, when a plurality of coins enter under the separation roller 25 and are almost jammed, the conveyance surface 27 of the conveyance belt 24 is supported and guided at a position below the separation roller 25. The movable guide 29 that moves is the transport surface 27 of the transport belt 24
Simultaneously, the coins are pushed downward to allow the coins to sink downward, so that the separation roller 25 can easily separate the overlapped coins, and the coins are less likely to be jammed.

Further, in addition to the normal feeding operation, when a coin jam occurs or when a coin jam occurs, the transport belt 24
Even when reversing
Since the guide is supported and supported, the load applied to the transport belt 24 can be reduced and the transport belt 24 can be prevented from being damaged.

Further, since the movable guide 29 has elasticity, the downward movement of the movable guide 29 can be permitted, and the movable guide 29 returns to the initial position before being pushed from the position pushed downward. it can.

Further, as shown in FIG.
A sensor 41 may be provided as detecting means for detecting that the stopper portion 34 of the movable guide 29 has moved down to the lower limit position. As the sensor 41, a contact switch is used in which a contact is switched when the stopper portion 34 contacts and is pushed. Then, by detecting that the movable guide 29 has moved down to the lower limit position by the sensor 41, it is possible to grasp the situation of the coin jam and to take measures such as clearing the coin jam.

That is, as shown in FIG. 8, a control means 42 for controlling the motor 38 by inputting a detection signal from the sensor 41.
Thereby, the situation of the coin jam can be grasped and measures such as clearing the coin jam can be taken. The control means 42 functions to drive the transport belt 24 in the feeding direction F by the motor 38 at the time of coin feeding, and to drive the transport belt 24 in the reverse direction by the motor 38 when the sensor 41 detects the lowering of the movable guide 29. have.

Then, under the control of the control means 42, the sensor
When the lowering of the movable guide 29 is detected at 41, the transport belt 24
Immediately in the reverse direction, it is possible to prevent the occurrence of jamming of coins that can be bitten too hard to solve.

The elasticity of the movable guide 29 is shown in FIG.
If it is set to be weaker than that used in the embodiment shown in FIG. 5, when the coin is likely to be jammed even a little, the movable guide 29 immediately descends, and the transport belt 24 can be reversed, so that It is possible to more reliably prevent the coin from being jammed.

The detecting means is not limited to the sensor 41 such as a contact switch, but may be a mechanical switch or a photo sensor.

In each of the above embodiments, the movable guide 29 is located at an initial position where the upper surface of the guide portion 32 is substantially flush with the upper surface of the fixed guide 28 and no deformation force is applied. The upper position of the upper surface of the fixed guide 28 may be substantially flush with the upper surface of the fixed guide 28, and the stopper portion 34 may always be elastic at the position where the stopper portion 34 contacts the lower surface of the fixed guide 28. 24 guides can be ensured.

The movable guide 29 has a cantilever structure supported by a fixed portion 33 at one end. However, both ends corresponding to the feeding direction F are supported by the fixed guide 28, and a guide portion 32 intermediate the movable guide 29 is provided. The same operation and effect can be obtained even if is configured to move in the vertical direction.

The movable guide 29 is not limited to a leaf spring.
For example, the same operation and effect can be obtained even if the elastic member is made of a metal plate and is urged upward by another elastic member such as a spring.

Further, the fixed guide 28 and the movable guide 29 are integrally formed so that only the movable guide 29 moves up and down, and the movable guide portion 29 is elastically moved up or down by using another elastic body. The same operation and effect can be obtained even when the biasing is performed.

The structure of the coin feeding device 13 can be similarly applied to the coin storage section 18 of the coin receiving and dispensing machine, and the same operation and effect can be obtained.
