Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin feeding device for feeding coins received in a batch by detecting the denominations of the coins one by one.

[0002]

2. Description of the Related Art Conventionally, a coin sending device is, for example, an actual open flat 7
As described in JP-A-6861 or JP-A-7-6862, a coin storage hopper is provided above the outer peripheral edge side of the rotating disc, and the coin storage hopper has a surface facing the rotating disc. A coin passage having a reference passage wall portion for guiding coins delivered by centrifugal force and a coin passage passage along which the coins delivered along the reference passage wall portion face each other with a gap therebetween is formed. , The coin passage is provided with an elastically deformable pressing member such as a sponge material that pushes the coin against the rotating disc to move along the reference passage wall portion, and sends the coin along the reference passage wall portion of the coin passage. A detection sensor for detecting the coins is provided.

The detection sensor is of a light emitting and receiving type which projects and receives small circular detection light. When the coin passes, the detection light is blocked so that one coin is sent out and the detection light is blocked. The time corresponds to the diameter of the coin and the denomination of the coin is determined.

[0004]

However, in the conventional coin feeding device, the coins moved along the reference passage wall portion are detected by the detection sensor, but the pressing member for causing the coin to follow the reference passage wall portion. Since the coins come into contact with each other and slide, the pressing member is liable to deteriorate, and there is a problem that it becomes uncertain to cause the coins to follow the reference passage wall portion due to the deterioration.

Further, by providing the line sensor as the detection sensor along the passage width direction, the denomination of the coin can be discriminated within the light-shielding range corresponding to the diameter of the coin without the coin extending along the reference passage wall. However, since the passage width is adjusted to a size that allows a maximum-diameter coin (for example, a 500-yen coin) to pass through, when a small-diameter coin (for example, a 1-yen coin) is continuously moved, two coins are placed on the line sensor. The coins cannot be detected reliably, for example, when the coins are lined up at the same time (see FIG. 12), and the coins are erroneously discriminated as coins having a diameter larger than that of the small diameter coins.

The present invention has been made in view of the above-mentioned circumstances, and coins can be sequentially drawn out one by one with respect to a detection sensor provided at the exit of a coin passage, and coins can be reliably detected. The purpose is to provide a device.

A tension spring 96 for urging the stopper piece 92 to swing upward is connected to the right end of the support piece 93, and the central lower surface of the support piece 93 swings the stopper piece 92 downward against the bias. The solenoid 97 is connected.

Further, as shown in FIG. 8, a coin storage hopper
An operation panel 101 is formed at the front end of the upper surface 38 of the 32, and an operation section 102 and a display section 103 are formed on the operation panel 101. Various keys such as a start key, a stop key, and a numeric keypad are arranged on the operation unit 102. The display unit 103 can display the number of denominations, the number of batches, and an alarm.

Further, as shown in FIGS. 2, 3 and 9, a cover 111 is detachably attached to cover the entire area of the coin storage hopper 32. The cover 111 has an upper surface portion 112 and a peripheral surface portion 113 formed so as to project downward from the periphery of the upper surface portion 112, and the peripheral surface portion 113 is the peripheral surface portion of the coin storage hopper 32.
It is fitted or loosely fitted to the outer periphery of 39 and the lower end of the peripheral surface portion 113 is joined to the flange portion 42 of the coin storage hopper 32,
The entire area of the coin storage hopper 32 can be covered.

As shown in FIG. 3, the cover 111 is removed from the coin storage hopper 32, the upper and lower surfaces thereof are inverted, and the cover 111 is inserted into the recess 2 of the base 1 so as to face the lower side of the delivery port 68. The coins sent from the sending port 68 can be received through the 51. Therefore, a coin storage space 114 for receiving and storing coins is formed inside the cover 111 used as a carton.

Next, the operation of this embodiment will be described.

When counting coins, the cover 111 is removed, the upper and lower surfaces of the cover 111 are inverted, and the coins are inserted into the recesses 2 of the base 1 and faced below the delivery port 68.

Coins are inserted into the coin storage space 43 through the hopper opening 40 of the coin storage hopper 32. At this time, as shown in FIG. 4, when a large amount of coins are thrown into the coin storage space 43, some coins are placed on the inclined wall 45 to support the weight of the coins, so that the rotary disk 11 is covered. The load can be reduced. Further, when the amount of coins inserted into the coin storage space 43 is small, coins directly inserted from above onto the rotating disk 11 bounce to cause a coin standing, and the standing coins are raised on the inclined wall 45. In such a case, the coin falls down halfway up the sloped wall portion 45, and even if it rises up to the upper end of the sloped wall portion 45, it abuts against the peripheral wall portion 44 and falls over. Is slid down on the rotating disk 11 due to the inclination of.

By selecting the counting mode or the batch mode with the operation unit 102 and operating the start key, the drive motor 22 is driven and the rotary disk 11 is rotated. In the counting mode, the number of coins is counted and the number of coins is displayed for each coin. In batch mode,
First, for the denomination detected by the line sensor 81, an arbitrary number of batches such as 100 is sent.

It should be noted that, even if the coin is rotated and moved along the inclined wall portion 45 or the coin is leaned against the inclined wall portion 45 by the rotation of the rotating disk 11, the coin is rotated to the protruding wall portion 46. By abutting the moving coin, the coin can be forcibly dropped on the rotating disk 11. Further, the protrusion 20 of the rotating disk 11 can be eccentrically rotated to loosen the coin in the coin storage space 43.

The coins placed in surface contact with each other on the rotating disc 11 are moved radially outward by the centrifugal force generated by the rotation of the rotating disc 11, and some of the coins are introduced into the coin passage 51 through the introduction passage portion 52. Directly, some coins come into contact with the introduction guide edge 59b of the passage member 58 and move along the introduction guide edge 59b and the following introduction guide edge 59a and enter the entrance portion 52a of the introduction passage portion 52. To do.

Since the delivery body 14 having a high coefficient of friction is arranged on the inner peripheral edge side of the rotating disk 11, a rotating force is reliably applied to the coin on the inner peripheral edge side of the rotating disk 11 to act on the coin. It is possible to strengthen the centrifugal force to reliably move the outer peripheral edge. Similarly, since the delivery body 15 having a high coefficient of friction is disposed on the outer peripheral edge side of the rotating disk 11, a centrifugal force that reliably applies a rotational force to the coin entering the introduction passage portion 52 and acts on the coin is provided. The force can be strengthened so that the coin is reliably moved to the outer peripheral edge side, and the peripheral edge of the coin can be brought into contact with the first passage wall 54. Also,
Since the upper surface of the metallic rotating disk 11 having a smaller friction coefficient than the sending bodies 14 and 15 faces between the sending bodies 14 and 15 on the inner peripheral edge side and the outer peripheral edge side of the rotating disk 11, let's enter the introduction passage portion 52. It is possible to reduce slippage between the coin and the coin and weaken the centrifugal force acting on the coin to weaken the impact of hitting the coin in the introduction passage portion 52.

The coin entering the introduction passage 52 is a rotating disc.
While being moved a long distance along the outer peripheral edge side of 11, a strong centrifugal force is applied to surely abut the first passage wall 54 and enter the lower side of the sphere 71 on the upstream side of the outlet passage portion 53.

As shown in FIG. 10, when the coin C enters the lower side of the sphere 71, the sphere 71 rises against the elastic body 75 according to the thickness of the coin C. Biasing force of elastic body 75 and sphere 71
Since the coin C is pressed against the delivery body 15 of the rotating disc 11 by its own weight, the coin C moves in the circumferential direction together with the rotating disc 11 while maintaining the joined state with the delivery body 15. And FIG.
As shown in, before the coin C moves away from the lower side of the upstream side sphere 71, the moving direction front edge of the coin C enters the lower side of the downstream side sphere 71, and The coin C is rotated by the sphere 71 while maintaining the joined state with the sending body 15.
Move in a circumferential direction with 11.

The coin C, which is pressed by the sphere 71 on the downstream side and moves in the circumferential direction together with the rotating disk 11, abuts on the leading guide edge 60 of the passage member 58 and rotates along the leading guide edge 60. It is guided to the outside of the disk 11 and passes through the line sensor 81.

The line sensor 81 detects the delivery of one coin by blocking the detection light when the coin passes, and determines the coin denomination and the presence of a coin based on the detection light shielding range corresponding to the diameter of the coin. Distinguish between coins and coins without holes.

At this time, the coins can be sequentially drawn to the line sensor 81 one by one by the sphere 71 arranged in the drawing passage portion 53. That is, FIG. 12 shows an explanatory view in the case where the sphere 71 is not provided, and since the passage width of the outlet passage portion 53 is formed to have a size that allows the passage of the maximum diameter coin (for example, a 500-yen coin), When small-sized coins C1 (for example, 1-yen coins) are continuously moved, the preceding coin C1 moves along the second passage wall 55 and the succeeding coin C1 moves along the first passage wall 54. As a result, two coins C1 are lined up on the line sensor 81 at the same time, and the coin is erroneously discriminated as a coin having a diameter larger than the diameter of the small coin C1. On the other hand, by providing the sphere 71, even if the coins move continuously, the coins are moved in the circumferential direction along the rotating disk 11 so that the coins are moved along the second passage wall 55 from the lead-out guide edge 60. Line sensor 81 can be sequentially derived one by one,
Can reliably detect coins.

The coins passing through the line sensor 81 are discharged into the chute 67, and are discharged through the chute 67 into the coin storage space 114 of the cover 111 arranged in the recess 2 from the outlet 68 of the base 1. To be done.

Then, in the counting mode, after all the inserted coins are counted and sent out into the cover 111, the number of coins of each denomination is displayed on the display unit 103.

In the batch mode, first, the denominations detected by the line sensor 81 are counted, and when coins of different denominations or unidentifiable coins such as counterfeit coins are detected,
The solenoid 97 is actuated, the stopper 91 stops the coin next to the corresponding coin, and the display unit 103 displays an alarm. Then, a predetermined number of batches, for example 100
When detected at 81, the next coin of the 100th coin is stopped by the stopper 91, and only the 100th coin is sent out.
