That is, the high speed transfer roller 40 can be effectively reduced the counting time by the roller 41 is positioned in a horizontal state with the plane of the conveying port 13 and pushed again at a constant speed by the rotational force when the coin is introduced. .

For example, when the coin is transferred only by the rotational force of the rotating plate 20 to pass through the counting sensing unit 30, the coin has a speed deviation according to the size and weight of the coin, and the counting sensing unit ( On the 30) side, a large coin and a small coin are in contact with each other, causing malfunction of the counting detector 30.

On the other hand, the frame 10 has a return discharge port 15 formed by cutting the side wall 14 so as to return the injected defect or foreign matter, is installed on the frame 10 above the return discharge port ( 15) the forced return unit 60 formed with the opening and closing protrusion 61 for opening and closing the lift plate 60 and the forced return unit 60 to return the defective coin or foreign matter when the rotating plate 20 is reversely rotated, and the discharge outlet An elevating member 53 for opening 15 is provided.

That is, the frame 10 has a return discharge port 15 formed so as to return the defective coin or foreign matter to the outside by cutting the side wall 14 on the opposite side of the transfer port 13, this return discharge port 15 Is in communication with the appearance side return port (2) of the coin counter (100).

The forced return unit 60 is installed on the upper side of the frame 10 to open and close the return discharge port 15, as shown in FIG. The protrusion 61 serves as a side wall of the frame 10 in a state where the return discharge port 15 is sealed. Therefore, the coin accommodated in the coin receiving groove 21 of the rotating plate 20 is smoothly transferred in the rotating plate 20 along the opening / closing protrusion 61 which seals the return discharge port 15, and the transfer hole 13 is moved. Will be dispensed through.

The elevating member 53 lifts or returns the forced return portion 60 and opens or closes the return discharge port 15 by the opening / closing protrusion 61 protruding from the bottom thereof, and both sides of the forced return portion 60. A flange 62 is formed on the shaft 62, and the shaft of the solenoid that is the elevating member 53 is coupled to the flange 62, and when the power is applied to the solenoid, the shaft is moved inward to lift the forced return portion 60. (See a, b of FIG. 6). Accordingly, the return discharge port 15 sealed by the opening / closing protrusion 61 maintains an open state. Reference numeral 54 is for fixing the elevating member 53 to the intermediate cover plate is manufactured so that there is no interference during the lifting of the forced return unit (60). Of course, when the elevating member 53 is fixedly installed in the structure located above it can be omitted.

At the same time, the motor 51 and the high speed transfer roller 40 of the rotating plate 20 rotate in the reverse direction to transfer the defective coin or foreign matter on the rotating plate 20 to the return discharge port 15 side and to the transfer hole 13 side. The coin or the foreign matter is prevented from entering, and is easily discharged to the outside through the return discharge port (15). Of course, this series of operations is preferably controlled according to the control sequence programmed in the control unit.

A partition wall 63 protruding downward is formed inside the rotational track (see FIG. 5).

In more detail, the partition 63 is installed between the rotation paths between the coin accommodation groove 21 and the elliptic protrusion 22 so that only the coins accommodated in the coin accommodation groove 21 are transferred to the transport port 13. Be sure to In addition, when another coin is transported in addition to one coin accommodated in the coin receiving groove 21, the other coin is separated by the partition 63 located inside the rotation trajectory of the coin receiving groove 21.

For example, the coin receiving groove 21 is designed to be smaller than the sum of the diameters of two smallest coins (for example, 50 won) for counting, so that one coin is accommodated in the coin receiving groove 21 while the other coin is accommodated. If it is accommodated over so as to protrude to the outside so as to hit the partition 63 during rotation of the rotating plate 20 to be separated.

And the transfer path 12 is provided with a semi-arc shaped curved portion so that the coin forced by the high-speed transfer roller 40 passes through the counting sensing unit 30 in close contact with the one side wall, the impact on the curved portion Shock absorbing member 16 for absorbing is provided.

That is, the coin forcedly transferred by the rotational force of the high-speed transfer roller 40 is shaken from side to side or irregularly deflected when passing through the counting detector 30 when the transfer path 12 is in a straight line to detect value according to the size of the coin. It will cause false detection. Accordingly, a portion of the transfer passage 12 is provided as a half arc-shaped curved portion, and the coin forcedly transferred by the high speed transfer roller 40 at a constant speed passes through the coefficient sensing unit 30 while being in close contact with one side of the wall. By doing so, it is possible to accurately detect the value of the coin according to the size by preventing the left and right shake or irregular deflection of the coin.

The shock absorbing member 16 is provided with a shock absorbing material such as a resin material so as to prevent the coin forcedly transported by the rotational force of the high speed transmission roller 40 to be thrown out while turning along the curved portion.

Hereinafter, with reference to the above-described technical configuration and the accompanying drawings will be described in detail the effect of the coin counter according to the present invention.

First, when a user (passenger) of the public transport puts a coin of a proper fee into the coin inlet 1 of the coin counter 100, the coins fall to the rotating plate 20 located below the coin inlet 1.

At this time, if the coin input to the rotating plate 20 is detected by the proximity sensor 52 installed on the bottom surface of the receiving portion 11 of the frame 10, the controller (not shown) based on the detection signal of the proximity sensor 52 The motor rotates the rotating plate 20 in one direction by driving the motor 51 and at the same time drives the high speed transmission roller 40 to rotate the roller 41 in one direction.

Accordingly, the coins in the rotary plate 20 are pushed outward by the centrifugal force, respectively, are accommodated in the coin receiving grooves 21 arranged at regular intervals, and transported, and are sequentially discharged to the transfer port 13.
