Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a coin dispensing machine that is incorporated into a vending machine, a money exchange machine, etc. and dispenses change coins or exchange coins, and particularly relates to a coin dispensing machine that dispenses change coins or exchange coins. The present invention relates to a coin sending device that sends out coins to a coin passage using centrifugal force and conveys the coins in the coin passage by a belt.

[Conventional technology]

In conventional coin feeding devices, coins are fed onto a rotating disk, and the centrifugal force generated by the rotation of the rotating disk moves the coin to its periphery, allowing only one coin to pass above the periphery of the rotating disk. A coin thickness regulating member disposed at a height of 100 cm allows the coins to be layered in a single layer in the thickness direction and sent from the rotating disk to the coin passage extending outward, and onto the conveyor belt provided above the upper surface of the coin passage. Therefore, the coins are conveyed while being pressed against the upper surface of the coin passage, and after performing necessary processing such as counting or identification, the coins are sent out of the device.

A pulley supporting the conveyor belt is supported by a biasing support mechanism using, for example, a spring so that the conveyor belt moves up and down in accordance with the thickness of the coin being conveyed.

In addition, the method for driving the conveyor belt and the rotating disk has been to use dedicated motors to drive each separately.

[Problem that the invention seeks to solve]

The coins sent to the coin passage by the rotating disk are conveyed by being pressed against the upper surface of the coin passage by a conveyor belt provided above the upper surface of the coin passage, so the upper surface of the coin passage is abraded by the coins. ,
A material with a small coefficient of friction and excellent wear resistance must be selected for the coin passage, and since such materials are very expensive, this becomes an obstacle when considering cost reduction of the device. Furthermore, with this type of conveyance method, the coins being conveyed are easily damaged, the durability of the conveyor belt is reduced, and additional equipment is required to urge the conveyor belt along the coin path and move it up and down. There was a problem that a force support mechanism was required and the mechanism became complicated.

In addition, since separate dedicated motors were directly installed to drive the conveyor belt and rotating disk,
Two motors are required, which increases the cost, and each motor needs to be installed in two locations, making it difficult to utilize space. In addition, the conveyor belt and rotating disk are driven and controlled by separate motors. For example, if the driving of the rotating disk is not stopped even though the driving of the conveyor belt is stopped, coins may be pushed into the coin passage from the rotating disk, causing a coin jam, or the driving of the rotating disk may be stopped. If the drive of the conveyor belt is not stopped at the same time, a problem occurs in the flow of coins, such as when the conveyor belt runs idle even though no coins are fed into the coin passage.

The present invention was made in view of the above-mentioned points, and the first object is to provide a coin dispensing device with an improved coin conveyance structure in a coin passage, and the second object is to provide a coin dispensing device that has an improved structure for conveying coins in a coin passage. An object of the present invention is to provide a coin dispensing device which simultaneously drives the coins.

Dust removal holes 20 are provided through the upper and lower surfaces of the rotary disk 11 to remove dust that has entered the rotary disk 19 .

Along the outer peripheral edge of the rotating disk 11, the rotating disk 1
A peripheral wall 21 is disposed to support a coin that moves to the periphery due to the centrifugal force of 1, and a notch 22 is provided in a part of this peripheral wall 21. A coin passage 23 is provided along the direction.

A coin guide piece 24 that guides coins moving along the peripheral wall 21 toward the center of the rotating disk 11 is arranged on the entrance side of the coin passage 23. The side (the left side in FIG. 2) is placed on the peripheral edge 11a of the rotating disk 11, and the end side is placed close to the center of the rotating disk 11, and the coins cannot pass through the rotating disk 11. It is placed facing the top.

A coin thickness regulating member 25 is disposed above the rotating disk 11 extending from the terminal end of the coin guide piece 24 to the coin passage 23 to send the coins into a single layer in the thickness direction to the coin passage 23. The coin thickness regulating member 25 is arranged at a height relative to the upper surface of the rotary disk 11 that allows only one coin to pass through the coin passage 23, and has a regulating edge that regulates the passage of coins from the second layer or higher. 26 is arranged such that the starting end side of the coin passage 23 is continuous with the terminal end of the coin guide piece 24, and the starting end side is arranged as a starting point and moves away from the center of the rotating disk 11 as it goes in the rotation direction F of the rotating disk 11. That is, it is arranged so that the width of its overlap with the peripheral edge 11a of the rotating disk 11 is reduced, and its terminal end is located on the peripheral edge 11a of the rotating disk.

The coin passage 23 includes a lower passage plate 28 whose upper surface is disposed substantially on the same plane as the upper surface of the rotating disk 11 and in which a long slot 27 is formed extending from the starting end side to the terminal end side of the coin passage 23, and a lower passage plate 28 whose lower surface is arranged to accommodate coins. It has an upper passage plate 29 arranged substantially on the same plane as the lower surface of the thickness regulating member 25, and on the lower surface side of the lower passage plate 28, a pair of pulleys are provided at the lower part of the starting end side and the terminal end side of the long groove hole 27. 30 and 31 are provided respectively, and this pulley 3
A part of the belt 17 that spans the disk driving pulley 13 is hung on the belts 0 and 31, and the belt 17 projects from the long slot 27 onto the coin passage 23 on the upper surface of the lower passage plate 28. The coin passage 23 is supported by the rotation of the belt 17 in the conveyance direction.
The coins sent in are conveyed toward the end of the coin passage 23 while being pressed against the lower surface of the upper passage plate 29.

Furthermore, notches 32 and 33 are formed in the lower passage plate 28 and the upper passage plate 29 so as to face each other facing the coin passage 23.
A sensor 34 is disposed in a substantially U-shape, with both ends facing the upper and lower surfaces of the coin passage 23, and detects, for example, magnetism of the coins conveyed through the coin passage 23 to count or identify the coins. , a rotary solenoid 3 is installed on the starting end side of this sensor 34.

A branching member 37 made of a roller that takes coins into the coin passage 23 and returns them to the rotating disk 11 for branching is disposed at a connecting portion between the rotating disk 11 and the coin passage 23 on the rotation direction F side.

Next, the operation of this embodiment will be explained.

The coins supplied onto the rotating disk 11 move to the periphery of the rotating disk 11 due to the centrifugal force caused by the rotation of the rotating disk 11, and then move along the periphery.
The coin is moved toward the center of the rotating disk 11 by the coin guide piece 24. Then, when the coin guide piece 24 reaches the end and is no longer restricted, the coins in the lowest layer touching the upper surface of the rotating disk 11 are transferred to the rotating disk 11.
Due to the centrifugal force of 1, the coin jumps out in the direction of the coin and enters under the coin thickness regulating member 25.

Then, the coins that have entered under the coin thickness regulating member 25 and are sent out to the coin passage 23 are removed from the belt 1.
Coin passage 2
3 is transported.

On the other hand, the coins in the second or higher layers that were on the upper surface of the coins fed into the coin passage 23 come into contact with the regulating edge 26 of the coin thickness regulating member 25 and move along the regulating edge 26. Then, it moves along the periphery of the rotating disk 11 again.

Note that the rotation of the rotating disk 11 and the start and stop of the rotation of the belt 17 in the coin passage 23 are always at the same time, so that the coins flow smoothly through the rotating disk 11 and the coin passage 23.

In addition, the rotational speed of the rotating disk 11 and the coin passage 23
The conveying speed of the belt 17 in can be easily set by changing the diameter of the disc drive pulley 13.

〔Effect of the invention〕

According to the present invention, the coin conveying belt is disposed in a protruding state from the lower side of the coin passage onto the coin passage,
Since the coins sent from the rotating disk to the coin passage are carried on a belt, there is less contact pressure between the coins and the coin passage, and there is less wear on the coin passage. There is no need to use expensive materials with excellent durability, which reduces the cost of the device.Furthermore, the coins transported through the coin passage are less likely to be scratched by friction with the coin passage, and the durability of the belt is improved. Furthermore, since there is no need to bias and support the belt on the coin passage surface as in the conventional case, the mechanism can be simplified.

In addition, a part of the belt that transmits rotation from the motor to the rotating disc is also used for coin transport to transport coins in the coin passage, so it is possible to drive the rotating disc and belt with one motor. It is possible to reduce the number of parts such as motors that drive the rotating disk and belt separately, which reduces the cost of the device, and also ensures that the rotation of the rotating disk and the belt start and stop at the same time. Since the timing is right, the coins can flow smoothly in the rotating disk and the coin passage without being stagnant or having gaps.
