[Problems to be solved by the device]

 However, since the coin sorter is designed to process coins at high speed, when a coin that does not correspond to the designated denomination is dropped into the sorting hole 13, the momentum of the coin is too strong, For example, in FIG. 9, it dances as shown by the solid line and the chain double-dashed line, moves in the selection hole 13 while passing through the guide member 20 in that state, and rides on the edge of the selection hole 13, There was a problem that it passed through the sorting hole 13 without being excluded. The present invention solves such a problem, and when coins that do not correspond to the designated denomination are about to be removed into the sorting hole, no matter what the posture of the coin is, The coins can be reliably guided and excluded into the sorting hole.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention extends a coin passage, a reference rail and a moving belt from a peripheral portion of a turntable, and provides a coin discriminating means along a coin transfer direction at an intermediate portion of the coin passage. In a coin sorting device that is configured by sequentially arranging a sorting means and a narrow sorting hole, the width is gradually narrowed along the coin transfer direction and is formed by an inclined portion that is gradually inclined toward the coin passage side. And a side surface that is continuous with the outer edge of the inclined portion and that is formed by an upright side surface portion that gradually inclines toward the sorting hole side along the coin transfer direction. It is characterized in that it is provided above and spaced apart from both the coin passage and the sorting hole.

[0005]

[Action]

 Therefore, the coins ejected from the turntable and transferred by the transfer belt along the reference rails of the coin passage are discriminated by the discriminating means and then based on the discrimination result of the discriminating means in advance. Coins corresponding to the designated denomination are passed through the sorting hole as they are, and coins not corresponding to the designated denomination are dropped into the sorting hole after the transfer direction is changed by the sorting means. Will be eliminated. When a coin is removed from the sorting hole, no matter what the posture of the coin, the coin drop guide consisting of the slanted part and the upright side part allows the coin to pass through the coin drop guide and get on the edge of the sorting hole. Lifting is blocked, and it will be smoothly guided as it is into the sorting hole.

FIG. 1 is a plan view of the main part of the coin sorting device, in which an annular guide 2 for arranging the coin A along the inner surface is provided above the outer peripheral part of the turntable 1 capable of receiving a large amount of coins A. On the outer peripheral portion of the turntable 1, a regulation plate 3 for regulating the thickness of only one fed coin is arranged, and a guide member 4 is arranged on the outer side of the regulation plate 3. At the end of the reference rail 6, which is laid on the side of the coin passage 7 extending from the site, facing the rotating disc 1, a guide roller 5 for suspending the width of the coins sent from the rotating disc 1 is mounted on the end. There is. On the extension of the reference rail 6 and on the side of the coin passage 7, the reference rail 14 is fixed through a part of the sorting means 10 described later, and the width of the coin passage 7 near the reference rail 14 is wide. A coin storing opening 15 having a width substantially the same as the width of the coin passage 7 is formed in the rear of the narrow sorting hole 13 (on the left side in FIG. 1), and the coin is opened from above the outer peripheral portion of the turntable 1. A transfer belt 8 which extends along the reference rails 6 and 14 while pressing the coin from above the storage opening 15 is extended in a plane inclined so that the end of the coin is moved toward the reference rail 14 side. Then, the portion of the transfer belt 8 located above the selection hole 13 is configured to be pressed toward the selection hole 13 side by the drop roller 17 which is elastically biased downward.

Further, a coin discriminating means 9 for discriminating the denomination and authenticity of the coin is provided above the front of the coin passage 7, and the coin passage 7 is provided between the reference rails 6 and 14. When a part of the projecting part comes into contact with the coin, the sorting means 10 is provided which can be dropped into the sorting hole 13 while changing its posture. The sorting means 10 includes the rotary solenoid 10a and the rotary solenoid 10a. The shaft 10b is rotated by the shaft 10b, and the semicircular portion at the upper end of the shaft 10b is cut out so that only the other semicircular portion 10c (the semicircular portion shown in FIG. 1) is projected onto the upper surface of the coin passage. When the protruding semicircular portion 10c is rotated 90 ° in the coin passage 7 clockwise in FIG. 1, the coin can be separated from the reference rail 6. A timing sensor 11 is provided in the coin passage 7 which is slightly distant from the shaft 10b in the direction of the turntable 1, and when a coin not corresponding to a designated denomination is detected by the timing sensor 11, the sorting means 10 is operated. The rotary solenoid 10a is operated to rotate the shaft 10 in the clockwise direction in FIG. 1 so that the protruding semicircular portion 10c is projected into the coin passage 7.

A coin drop guide 16 is installed from above the sorting hole 13 to the lateral side. As shown in FIGS. 3 and 4, the coin drop guide 16 includes a flat surface portion 16a, an inclined portion 16b, and a standing side surface. The flat portion 16a is horizontal, the inclined portion 16b has a width that gradually narrows in the coin transfer direction, and is inclined toward the coin passage 1 side. Shall gradually incline toward the sorting hole 13 side along the coin transfer direction. Further, the lower ends of the inclined portion 16b and the standing side surface portion 16c of the coin drop guide 16 have the same height as shown in FIG. 4, and the distance between the lower end edges of the inclined portion 16b and the standing side surface portion 16c and the upper surface of the coin passage 7. C is an interval through which one coin can pass.

Therefore, when the coins are sent out from the turntable 1 one by one and the sorting process is performed while moving the coins on the coin passage 7, the coins are discriminated as the denominations corresponding to the denominations designated in advance by the coin discriminating means 9. As shown in FIGS. 5 and 6, the coin R is transferred by the transfer belt 8 while being laid on the sorting hole 13 and received in the coin storage opening 15, and the coin discriminating means 9 is also provided. The coin N discriminated as a denomination that does not correspond to the denomination designated in advance is separated from the reference rail 6 by the semicircular portion 10c of the shaft 10 protruding into the coin passage 7 of the sorting means 10, and As shown in FIG. 5, when a part is made to look into the selection hole 13, as shown in FIGS. 7 and 8, it is pressed by the drop roller 17 via the transfer belt 8 and stands up. like Even when the posture is changed, as shown in FIGS. 7 and 8, the coin drop guide including the flat surface portion 16a, the inclined portion 16b, and the standing side surface portion 16c and the coin drop guide 16 including the rising side surface portion 16c having the flat inclination are used. Is guided to change the posture, and the drop can be smoothly eliminated without accidentally passing over the selection hole 13. In this embodiment, the inclined portion 16b is connected to the flat surface portion 16a, and the rising side surface portion 16c is connected to the inclined portion 16b to form the coin drop guide 16. However, the coin with the flat surface portion 16a removed Even the drop guide 16 can sufficiently eliminate the guiding of coins into the sorting hole 13.
