Description

[Detailed Description of the Invention] The present invention relates to a coin jam detection device in a coin processing machine.

That is, in a coin processing machine configured such that a rotating disk aligns the coins fed by a supply belt around the circumference by centrifugal force and sends them out one by one from a sending section around the rotating disk to a sorting path side, the sending section side If a coin jam occurs while the coins are being sent out, the rotating disk can be immediately stopped and detected, and damage to the coin button and machine can be effectively prevented, and the structure is simple and can be carried out suitably. This is what we provide.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows an exploded perspective view of the main parts of the coin handling machine.
An endless supply belt 3 is installed below the hopper 2 into which a large amount of coins 1 can be input so that its rotation can be controlled. A sorting passage 6 for sorting extends from a part of the peripheral delivery section 5 that aligns the coins 1 on the rotating disk 4 by centrifugal force and sends them out one by one. belt l
The coins 1 are hung on one side facing the end of the sorting passage 6.
A counting sprocket 8 for counting while engaging and rotating is installed, and a packaging device and a coin holder are installed behind it, so that the structure is similar to the conventional structure.

A table ring 9 is erected around the rotating disk 4 except for the vicinity of the delivery section 5, and an inner wall member made of a wear-resistant raw hardened steel plate is attached to the inner peripheral surface of the table ring 9C to which a coin 1 is pressed. 10 is stretched.

In the vicinity of the delivery section 5, that is, in the notch part of the table ring 9 that serves as the inlet of the sorting passage 6-, a regulation block 11 for feeding the coins on the rotary disk 4 one by one into the sorting passage 6 is installed on the table. It is provided separately from the ring 9.

This regulation block 11 can be vertically adjusted by a knob 12 on the upper side thereof, and includes a thickness regulation member 11 that protrudes above the upper surface on the peripheral side of the rotary disk 4, an inner wall member 10 fixed to this, and a gap regulation member. It consists of 13.

The inner side of the rotating disk 4 of the thickness regulating member 11 is set at a position where the gap between its lower edge and the top surface of the rotating disk 4 exceeds the thickness of one coin to be sorted and is less than the thickness of two coins. The divided inner wall member 10 is fixed.

Further, a gap regulating member 13 is provided at a position close to the inner wall member 10 on the lower surface of the upwardly protruding end of the thickness regulating member 11 on the peripheral side of the rotating disk 4, and is fixed in an insulated state from the others. The lower end surface of the regulating member 13 is provided so that the gap with the upper surface of the rotary disk 4 exceeds the thickness of one coin to be sorted and has a height less than the lower edge of the inner wall member 10.

That is, for example, when the thickness regulating member 11 is formed of an insulating material, the gap regulating member 13 is directly fixed to the lower surface thereof, and the insulating material 14 is interposed between it and the inner wall member 10.

Further, the reason for providing a step in the gap between the inner wall member 10 and the gap regulating member 13 from the upper surface of the rotating disk 4 is that when the coin 1 is jammed in a wedge shape as shown in FIG. This is to allow the jammed coin 1 to come into contact with the corners of the rotating disk 4 and the gap regulating member 13.

In this device, the rotary disk 4 is made of a conductive material, and the conduction and insulation conditions between the rotary disk 4 and the gap regulating member 13 are monitored, and if the state of conduction and insulation changes between the two, In this case, the drive motor (not shown) of the rotary disk 4 etc. is automatically stopped when it is determined that there is a jam in the intake portion.

Additionally, the outer circumferential side of the rotating disk 4 is arranged such that the coin 1 placed on the upper surface of the outer circumferential side of the rotating disk 4 below the gap regulating member 13 is brought into pressure contact with the abutment member 16 and guided toward the delivery section 5 side. The abutment member 16 is set to move outwardly in conjunction with the sorting passage 6, and a detection rod 15 is obliquely provided above the circumference of the rotating disk 4, so that the detection rod 15 can touch the coin 1 on the rotating disk 4. It is configured to operate in contact with each other and to control the drive of the supply belt 3 according to the amount of coins 1.

Note that when the thickness regulating member 11 is formed of a conductive material, an insulating material is interposed between the thickness regulating member 11 and the gap regulating member 13.

However, during work, coins 1 are thrown into hopper 2.
The coins 1 on the rotating disk 4, which rotates as shown by the arrow A, are aligned along the inner wall member 10 by applying centrifugal force, and the coins 1 are fed to the rotating disk 4 by the supply belt 3, and the coins 1 are aligned along the inner wall member 10.
When reaching the side intake port, the coin 1 on the rotating disk 4 is guided while sliding against the abutment member 16, as shown in FIG.
Since the rotating disk 4 and the gap regulating member 13 are separated from each other, the rotating disk 4 and the gap regulating member 13 become insulated, and the coins that overlap the top surface of the coin 1 are joined to the inner wall member 10 as shown in the back of the figure, and 11 coins are taken in. The coins 1 are sent out from the IT delivery section 5 onto the sorting passage 6, and while being fed by the upper belt I, coins of different diameters are sorted on the sorting passage 6, and are engaged with the 1 dot counting sprocket 8. It is sent out while being counted.

In that case, on the intake side that is provided in front of the sending section 5,
As shown in FIG. 3, if the coins 1 are not aligned and a jam occurs, the inclined coins 1 will come into contact with the rotating disk 4 and the gap regulating member 13, causing a jam. A short circuit occurs through the coin 1, and the jam can be detected due to the short circuit, and the drive motor of the rotary disk 4 etc. can be automatically stopped to perform processing.

In addition, by operating the knob 12, the gap regulating member 113 can be moved up and down for adjustment.

In this way, the present invention provides a coin processing machine configured so that the coins fed by the supply belt are aligned around the rotating disk or by centrifugal force, and sent out one by one from the sending section on the peripheral side of the ID1 rotating disk to the sorting path side. Later, a gap regulating member made of conductive material was installed at a distance higher than one coin above the upper surface of the circumferential side of the rotating disk in front of the sending section, and the jammed coins were placed in the member. If they come in contact with each other, a short circuit will occur, causing damage to the
Since the drive motor is configured to be able to be stopped, if a coin jam occurs while the coins on the rotating disk are aligned and fed out one by one toward the sending section, the jammed coins will be transferred to the rotating disk. It is possible to short-circuit the gap regulating member and detect a jam, and it is also possible to automatically stop the drive motor of the rotating disk, etc., and to reliably prevent damage to coins and the machine. It has the feature that it can be easily implemented with a simple structure.
