DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for discriminating the authenticity of coins conveyed in a row and for arranging the sending direction in accordance with the authenticity. And a coin discriminating / sorting device for improving discrimination accuracy and simplifying the structure.

[0002]

2. Description of the Related Art Heretofore, a method has been adopted in which coins are conveyed while being pressed and slid by a belt on a conveying path surface made of zirconia, a kind of ceramic, nitrocarburized sheet metal or the like. With this transport method, coins can be transported reliably without deviating from the transport path surface even when subjected to vibration or impact.

[0003]

The prior art has the following disadvantages. The transport path surface made of zirconia or nitrocarburized sheet metal is easy to form a smooth surface and has good sliding characteristics, so while coins are transported smoothly, it is difficult to maintain the quality of the transport path surface and costs are high. Take it. In addition, since it is a configuration of the conveying path surface and the pressing belt,
The arrangement of the coin identification sensor is limited only to the upper side of the conveyance path surface, and it is difficult to improve the identification accuracy. Furthermore, if the quality of the transport path surface varies, this directly affects the coin identification accuracy.

[0004] The problem to be solved by the present invention is to solve the above problems of the prior art, and to improve the identification accuracy and simplify the structure by contriving the transportation means, to identify and distribute coins. Is to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a coin identifying and sorting apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the first embodiment, and FIG. 2 is a side view of the first embodiment. In these figures, the embodiment mainly includes three blocks, namely, a feeding section for coins, an identification section, and a sorting section. The feeding part is a flat belt 11 wound around pulleys on both sides without reference numerals, and a frame 12 on the left side of the figure.
, An optical sensor 13 and a reverse roller 14. coin
9 is loaded from above a rectangular cylindrical frame 12, and is placed on the upper surface of a flat belt 11 that is configured to rise to the right. Coin insertion, transmission type optical sensor consisting of a set of light emitting part and light receiving part
When detected by any one of the three sets, the flat belt 11 is activated based on the detection signal. In the course of being conveyed by the flat belt 11, the inserted coins 9 are separated one by one by a reverse roller 14 at the upper right end and sent to the next identification unit. The optical sensor 13 not only activates the flat belt 11 by detecting the insertion of coins, but also detects an abnormality that the coins 9 stand upright during conveyance and cannot be conveyed, and issues an alarm.

The discriminating portion is wound around pulleys on both sides without reference numerals, and moves in the horizontal direction. The flat belt 1 and the regulating frames 2A, 2B provided near the edges on both sides of the flat belt 1 are provided.
And the identification sensor 3 highlighted in oblique lines. Each of the restriction frames 2A and 2B is a U-shaped plate-like member that restricts the movement of the coin 9 so that the coin 9 does not jump up on the flat belt 1 or deviate to the left and right sides. As shown in FIG. 2, the identification sensor 3 is composed of two parts which are disposed so as to sandwich the upper part of the flat belt 1 from above and below, and can accurately identify coins 9 which are conveyed and passed from both sides. it can.

The sorting unit comprises a sorting gate 6 for deflecting coins 9 at right angles to the conveying direction of the flat belt 1, and a conveying means for the sorted coins 9, comprising a passage 15, a take-in roller 16 and a belt 17. . Distribution gate 6
As shown in Fig. 1, the left side end face is
And is rotatably supported about a horizontal axis 5 and driven by a solenoid 4. The belt 17 is wound around a pair of rollers (the take-up roller 16 is shown in the figure), and the coin 9 taken in by the take-in roller 16 is pressed against the surface of the passage 15 and is slid and conveyed. The edges of the passage 15 are folded back on both sides, thereby restricting the coin 9 from deviating in the vertical and horizontal directions.

In the first embodiment, the coins 9 sequentially fed one by one from the feeding section are placed in a row on the flat belt 1 and conveyed, and furthermore, while being conveyed, the coins 9 are controlled by the respective regulation frames 2A and 2B. Bounce and lateral deviation are limited. During the transportation, the identification sensor 3 identifies the authenticity and denomination of the coin. If the coin 9 is identified as a counterfeit coin, the solenoid 4 is activated by the abnormal signal of the identification sensor 3 and the sorting gate 6 jumps up as shown by the broken line in FIG. Move away from surface. Therefore, the abnormal coin 9 is conveyed by the flat belt 1 as it is, falls from the right end as shown by the arrow Q, and is returned to the input side by return means (not shown). When the coin 9 is identified as a genuine coin, no signal is output from the identification sensor 3, so that the solenoid 4 does not operate, and the sorting gate 6 has the guide surface 6a as shown by the solid line in FIG. 1
Remains in close proximity to the surface. Therefore, normal coin 9
Abuts on the guide surface 6a, is guided along the guide surface 6a, and is distributed in the direction of the arrow P as shown in FIG.
15, the sheet is conveyed by conveying means including a take-in roller 16 and a belt 17, and the process proceeds to the next step.

A modification of the identification sensor according to the first embodiment will be described with reference to FIG. FIG. 2A is a plan view thereof, and FIG. 1B is a side view thereof. This identification sensor 7
Is provided close to the upper side of the flat belt 1 on the coin loading side. Another modification of the identification sensor according to the first embodiment will be described with reference to FIG. 4 which is a side view thereof. The identification sensor 8 is provided near the lower side of the flat belt 1 on the coin loading side. As described above, the identification sensor is disposed close to the upper and lower sides of the flat belt 1,
There are three methods, such as the arrangement close only to the upper side or the arrangement close only to the lower side, and the method is appropriately selected according to the required accuracy of identification and the condition of the transporting means.

A second embodiment will be described with reference to FIGS. 5 and 6 relate to the main part, in which (a) is a plan view and (b) is a side view. The difference between the second embodiment and the first embodiment is that the coin 9
Means to prevent them from jumping or deviating to both sides. In the second embodiment, a round belt 10 wrapped around pulleys on both sides without reference numerals is used.
9 is held between the surfaces of the round belt 10 and the flat belt 1. Others are the same as those of the first embodiment, and the description is omitted. In FIG. 5, the identification sensor 3 </ b> A is of a type that is disposed close to the upper and lower sides of the flat belt 1 and separated by a round belt 10.
In the modification shown in FIG. 6, an identification sensor 8 is arranged close to only the lower side of the flat belt 1 instead of the identification sensor 3A in FIG.
