Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin separating device and a coin processing machine used in a game field, a bank, etc., and particularly, to identify a coin carried on a coin passage and identify the coin based on the identification result. The present invention relates to a coin separating device and a coin processing machine suitable for separating.

[0002]

2. Description of the Related Art Conventional coin processors such as a coin sorter, a coin counter, and a coin sorter / counter that have been conventionally used accelerate a coin fed from a rotating plate by a coin accelerating means to guide it to a coin passage. A coin is separated into a designated coin and a non-designated coin based on a detection signal of a sensor provided in the middle of the coin passage. A solenoid, a plunger, and the like that operate in synchronization with the sensor detection signal are used in this separation device.

[0003]

In the coin separating device used in the above-mentioned prior art, the coin separating speed is limited by the response speed of the plunger, solenoid, etc. There is a problem in that an output means or a special precision means is required, the apparatus becomes complicated, and a high development cost is required.

It is an object of the present invention to provide a coin separating device and a coin processing machine which do not newly bear development costs, have a simple device structure, are low in manufacturing cost, and can be easily separated at high speed.

[0005]

In order to achieve the above object, the coin separating apparatus of the present invention selects a coin as a designated coin and a non-designated coin based on a detection signal of a coin identification means provided in the middle of a coin passage. In the coin separating device for separating into two, the angular displacement by the clockwise rotation (CW) and the counterclockwise rotation (CCW) of the stepping motor is used as a means for separating the designated coin and the non-designated coin. It is a thing.

[0006] Further, the above object is to accelerate a coin fed from a rotary disc by a coin accelerating means to guide it to a coin passage, and to detect the coin based on a detection signal of a coin identifying means provided in the middle of the coin passage. In a coin processing machine including coin separating means for separating designated coins and non-designated coins, the coin separating means includes clockwise rotation (CW) and counterclockwise rotation (C) of a stepping motor.
This is achieved by a coin processor characterized in that the coin is separated into a designated coin and a non-designated coin by an angular displacement due to (CW).

[0007]

According to the above construction, the coin fed into the coin passage from the coin feeding rotary disc or the like is horizontally accelerated by the coin accelerating means and guided into the coin passage, and passes through the coin identifying means. Based on the detection signal from the coin discriminating means, the stepping motor of the coin separating means operates at a predetermined step angle in a predetermined rotation direction, and by a distribution plate attached to the output shaft of the stepping motor, for example, in the vertical direction. Designated coins and undesignated coins can be separated and stored separately.

EXAMPLES Before describing the examples of the present invention,
First, a coin processing machine as a comparative example of the present invention will be described with reference to the drawings. 5 and 6 are a cross-sectional view and a top view of the coin processing machine of this example, respectively. As shown in these figures, the coins 2 accumulated on the turntable 1 and sequentially guided onto the passage bottom plate 3 are accelerated by the accelerator 9 by the roller belt to move on the passage bottom plate 3 and the optical dark portion. When passing through the position sensor 4 and the photo sensor 6 at the installed position of 5, the camera 8 recognizes the shape, size, pattern, etc. via the ring strobe 7, and the controller 13
Then, it is determined whether the coin is a designated coin or a non-designated coin.

Accelerator 1 is used to prevent coins from stagnation.
Accelerated at 0, solenoid 16, distribution plate 17, spring 18
To reach the coin separating means, such as. Here, based on a signal from the controller 13, the solenoid 16 operates to operate the distribution plate 17, and the designated coin 23 is stored in the designated coin storage box 21, and the non-designated coin 24 is stored in the non-designated coin storage box 22. To do. The storage boxes 21 and 22 are provided with gates 19 and 20, respectively.

In this case, the speed of each of the accelerators 9 and 10 formed of roller belts is measured by the speed sensor 1 respectively.
1 and 12, the controller 13 controls the speed of the accelerator 10 to be slightly faster than the speed of the accelerator 9,
Coins do not become stagnant on the passage bottom plate 3.
Incidentally, the passage bottom plate 3 is provided with side plates 14 and 15 so that coins do not jump out of the passage.

In this example, coins can be separated at a speed of 20 ms to 30 ms, but the coin separation speed is
Since the response speed of the plunger, solenoid, etc. is limited, a large output means or special precision means is required for high-speed separation, and the sorting mechanism ages after tens of thousands of operations. There was a problem. Also,
Attempting to sort many types at the same time required that many solenoids. Also, because the coins are separated horizontally, the amount of sliding movement is large, and when the coins come into contact with the distribution plate and the speed slows down, the subsequent coins collide with this, and subsequently the subsequent coins collide with each other. However, there was a problem that the coin passage was clogged.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing an embodiment of the coin processor of the present invention, and FIG. 2 is a side view thereof. In these figures, the coins 53 supplied onto the rotary disc 51 are aligned by the centrifugal force of the rotary disc 51 driven by the rotary plate 51 along the regulation plate 52 provided around the coins, and are provided outward of the rotary disc 51. The coins are sequentially delivered onto the coin passage 66 via a guide plate (not shown).

The coin passage 66 is located on the right and left sides of the passage bottom plate 62 and the passage bottom plate 62 having substantially the same surface as the upper surface of the turntable 51. And a passage side plate 56 capable of adjusting

A coin accelerating means 63 including a roller 54 and a motor 55 for driving the rollers is provided near the periphery of the rotary disk 51 of the coin passage 66. The roller 54 of the coin accelerating means 63 causes the rotary disk 51 to rotate. The coin fed from is accelerated and is conveyed at high speed while sliding on the surface of the passage bottom plate 62 of the coin passage 66.

A coin identifying means 65 is provided downstream of the coin accelerating means 63 in the coin passage 66. When the coin 53 passes over the coin identifying means 65, for example,
A designated coin or a non-designated coin is discriminated, and a detection signal is output at the same time.

A coin separating means 64 is installed near the end of the coin passage 66, and the coin separating means 64 has a distribution plate 58 and a stepping motor 57 for driving the distribution plate 58.
And so on. The response speed of the coin separating means 64 can be set within 10 ms and high speed (6000 coins / minute)
You can separate the coins. The distribution plate 58 is located on the lower surface of the passage bottom plate 62 of the coin passage 66, and has a stepping motor 57.
Is connected to the output shaft of.

The coin 53 passing through the coin identifying means 65
Is a coin other than the designated coin, the coin identifying means 65
Based on the detection signal from the stepping motor 57 of the coin separating means 64, the stepping motor 57 rotates counterclockwise (CCW) at a predetermined step angle, and the tip of the distribution plate 58 connected to the output shaft of the stepping motor 57. However, the coin projects up onto the coin passage 66, flips up the coin onto the surface of the distribution passage 59, and guides it to the undesignated coin storage box 61.

Next, when the coin 53 passing through the coin identifying means 65 is not the designated coin in the same manner, the stepping motor 57 keeps the current excitation state and the coin is guided to the undesignated coin storage box 61. In the case of, the stepping motor 57 rotates clockwise (CW) at a predetermined step angle, the tip of the distribution plate 58 is pulled down from the coin passage 66, and the coin is designated through the lower surface of the coin distribution passage 59. It is stored in the coin storage box 60.

3 and 4 are modified examples of this embodiment. The coin distribution plate 58, as shown in FIG.
The coin distribution plate 58 may be vertically distributed behind the stepping motor 57, or as shown in FIG. 4, the coin distribution plate 58 may be arranged in front of the stepping motor 57.
It is also possible to use a method in which the numbers are distributed vertically. It is also possible to adopt a system in which the coin distribution plate 58 is distributed to the left and right depending on the installation position of the stepping motor 57.

Since the angular displacement of the stepping motor is used to sort the coins, the coin separation speed can be implemented within 10 ms, and the response speed is fast.
Moreover, the speed can be controlled freely. Also, by changing the angular displacement, it is possible to select various types with one unit. For example, as shown in FIG. 7, by changing the angle of the distribution plate 58 in multiple stages in the vertical direction, it becomes possible to sort multiple types of coins in multiple stages for each type, and also to improve durability. It has an excellent effect that the device can be downsized.

[0021]

According to the present invention, a novel and expensive development is made by using the angular displacement by the clockwise rotation (CW) and the counterclockwise rotation (CCW) operation of the stepping motor as the method of giving the displacement amount. The coin does not get stuck in the coin passage because it does not need to bear the cost, and the structure of the device is simple and the coins can be separated at high speed and vertically.
