Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a coin sorting device used in vending machines, game machines, etc.

(Prior Art) Conventionally, as this type of coin sorting device, for example,
As described in Japanese Unexamined Patent Publication No. 55-157085, the top plate is provided with a coin input slot, a coin return lever, and a coin return slot, and a fixed side plate, a movable side plate, and a chute side plate attached to the top plate. A coin sorting passage and a regular coin chute and a return chute branched from the coin sorting passage are provided, and regular coins and defective coins sorted from the coin sorting passage provided with a cradle and a magnetic material sorting device are separated into a regular coin chute and a defective coin chute. It is configured to pass through the coin return chute separately, and has a self-sufficient structure that integrates the coin input slot to the coin return slot, and requires a small installation space for vending machines, game machines, etc. Devices with advanced coin sorting capabilities are known.

(Problem to be solved by the invention) However, in such a conventional device, since the bad coin return chute and the regular coin chute leading to the coin return slot are provided branching off from the coin sorting passage, for example, bad coins When a large number of coins are inserted, the defective coin return chute is blocked and the defective coins are packed up to the junction point between the return chute and the regular coin chute, making it possible for the defective coins to pass into the regular coin chute. Even if the system had a 100% complete coin sorting function, there was a problem in that vending machines, game machines, etc. could be used illegally due to defective coins.

In addition, a coin sorting device equipped with a magnetic material sorting device that checks the coin material by a magnetic braking action can be used in a vending machine, in a direction that accelerates the coin rolling speed.
There has been a problem in that when the game machine or the like is tilted, defective coins pass from the coin sorting path to the regular coin chute.

(Means for Solving the Problems) The present invention solves the above-mentioned two problems at the same time by using one defective coin blocking piece, and completely prevents defective coins from passing into the regular coin chute after sorting. The purpose is to provide a means to prevent this.

Therefore, according to the present invention, in a coin sorting device configured such that the sorted regular coins and defective coins pass through the regular coin chute and the defective coin return passage, which are branched from the coin sorting passage, respectively, As shown in Fig. 1, a defective coin blocking piece 1 is rotatably attached to a chute side plate 2 by a pivot pin 3 so as to be able to protrude into the regular coin chute entrance, and an operating lever 4 for operating the blocking piece 1 is pushed into the chute. It is pivotably attached to the side plate 2 by a pivot pin 5, and is actuated by an actuating arm 6 that engages the actuating lever 4 with the blocking piece 1, and a defective coin that protrudes into the return chute and is in the return chute. It is characterized in that it is provided with a defective coin detection arm 7 and a balance weight 8 for detecting inclination.

(Function) According to the present invention, normally, as shown in FIG. 3, the operating lever 4 is in a balanced position by the balance weight 8, and the operating arm 6 is engaged with the pivot end of the blocking piece 1. , the blocking piece 1 is in the retracted position, and the movable bottom 7a at the free end of the defective coin detection arm 7 is in a position projecting upward from the inclined bottom 10 of the defective coin return chute 9.

In this state, regular coins such as nickel coins that have been subjected to the magnetic braking action pass from the rolling rail 11 in the coin sorting passage to the entrance 12a of the regular coin chute 12 as shown by arrow A.

In addition, bad coins are sorted into the sorting piece 1 as shown by arrow B.
3, the coin passes through the defective coin return chute 9, presses down the defective coin detection arm 7 and rolls onto the inclined bottom 10, as shown in FIG.
will be returned to. On the contrary, for the purpose of unauthorized use,
If the coin return slot is blocked and a large number of defective coins are inserted, and thereby the defective coins are stuffed into the defective coin return chute 9 as shown by the chain line C in FIG. 4, the defective coins D on the movable bottom 7a are pushes down the defective coin detection arm 7 as shown by arrow a, which causes the actuating lever 4 to rotate around the pivot pin 5 as shown by arrow b, and the actuating arm 6 engaged with the blocking piece 1 The blocking piece 1 moves onto the inclined convex portion 1a on the blocking piece 1, and thereby the blocking piece 1 rotates as shown by arrow c, and the blocking piece 1
The tip end 1b of the coin protrudes into the entrance 12a of the regular coin chute 12 as shown by the arrow d, thereby preventing the defective coin E inserted after the defective coin D from passing into the regular coin chute 13.

Additionally, if a vending machine, game machine, etc. is tilted for the purpose of unauthorized use, the tilt detection balance weight 8 moves in the direction of arrow e and moves the operating lever 4 to arrow b.
As a result, the tip 1b of the blocking piece 1 is rotated in the direction of the regular coin chute 1 as in the case described above.
The coin chute protrudes into the second entrance 12a to prevent defective coins from passing into the regular coin chute.

(Embodiment) The drawing shows an embodiment of the present invention, in which 14 is a front plate, 15 is a coin slot, 16 is a return lever, and 17
18 is a return port, 18 is a fixed side plate fixed to the top plate 15 with screws, etc., 19 is a movable side plate hinged to the fixed side plate 18 by a hinge pin 20, and a shoot side plate 2 is formed of plastic similarly to these side plates. is fixed to the top plate 14 and fixed side plate 18 with screws or the like, and a regular coin chute 12 and a defective coin return chute 9 are provided between the fixed side plate 18 and the fixed side plate 18.

The defective coin blocking piece 1 is L-shaped, and the pivot pin 3
is pivotally connected to the chute side plate 2 by a pivot pin 3.
By rotating the tip 1b around the chute side plate 2, the tip 1b passes through the opening 21 of the chute side plate 2 and is inserted into the regular coin chute 1.
2, and in order to operate this blocking piece 1, the chute side plate 2
At the position where the actuating arm 6 of the actuating lever 4, which is pivotally connected by a pivot pin 5, engages a stopper 22 provided at the pivot end of the blocking piece 1, the tip end 1b
is in a position retracted from the entrance 12a of the regular coin chute 12, the operating lever 4 rotates around its pivot pin 5, and the operating arm 6 moves toward the inclined protrusion 1 of the blocking piece 1.
By moving above a, the blocking piece 1 touches the pivot pin 3.
It is configured such that the tip portion 1b projects into the entrance 12a of the regular coin chute 12 by rotating around the coin chute 12.

The operating lever 4 is provided with a defective coin detection arm 7 and a tilt detection balance weight 8 in order to produce the above-mentioned rotation, and the free end of the defective coin detection arm 7 is connected to a window provided in the chute side plate 2. 23 into the defective coin return chute 9, and the movable bottom portion 7a of the free end portion is held in a position projecting upwardly from the bottom 10 of the return chute 9 by the action of the balance weight 8. Balance weight 8 is in slot 2
4 and a screw 25 so that the tilt detection sensitivity can be adjusted.

Further, in the figure, 27 is a cradle, 28 is a buffer lever, 29 is a magnetic material sorting device, and 30 is a cradle configured to detachably support the cradle 27.
Cradle support device according to No. 59-30110, 31 is a coin jagged check device according to Utility Application No. 59-30109,
32 shows a coin center hole checking device according to Utility Model Application No. 59-107529.

(Effects of the invention) According to the invention, one defective coin blocking piece protruded from the entrance of the regular coin chute can completely prevent unauthorized use due to the insertion of a large number of defective coins and unauthorized use due to tilting. This effect can be obtained.
