Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) 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 Patent Application Laid-open No. 55-157085, regular coins sorted through a coin sorting passage pass into a regular coin chute, fall through the regular coin chute, and cross the outlet at the lower end of the chute. A coin sorting device is known in which a micro switch actuating arm that rotatably protrudes from the coin is pushed down to be activated and sends a signal for passage of a regular coin. In order to prevent unauthorized operation of the microswitch operating arm due to inserted wire, etc., for example,
As described in Publication No. 6629, a blocking piece rotatably pivoted to one side plate of the chute at the exit portion of the lower end of the regular coin chute is made to protrude retractably into the regular coin chute through a window in the side plate of the chute. Something is known.

In addition, in Japanese Utility Model Publication No. 55-45488, a rotating pendulum plate is provided in the coin passage below the coin insertion position, and a minute gap is created between the protruding end of the pendulum plate and the side wall of the passage. A tamper-evident device is described that prevents the switch from being activated by inserting a wire through the input port.

(Problem to be Solved by the Invention) However, in recent years, due to the development of metal materials, extremely thin strips suitable for malfunctioning switches can be easily obtained. There is a problem in that the switch can be operated illegally.

Furthermore, in the above-mentioned tamper-evident device, when coins are continuously inserted, subsequent coins engage the protruding terminal and the pendulum plate cannot completely return to the passage open position, causing subsequent coins to remain in the passage. There is a problem with clogging.

The present invention aims to provide a coin sorting device configured to prevent unauthorized operation of the microswitch operating arm due to the above-mentioned wire, tape-like metal piece, etc., and to prevent erroneous operation due to continuous input of coins.

(Means for Solving the Problems) The present invention provides a system in which regular coins sorted from a coin input port through a coin sorting passage pass into a regular coin chute 7 and rotatably protrude across the outlet at the lower end of the chute. The coin sorting device is configured such that a regular coin passing signal is transmitted by pushing down and operating a micro switch operating arm 1, which has a lower engaging portion 2 that projects to a lower position of the micro switch operating arm 1. A micro switch operation prevention lever 4 is pivotally attached to the side plate 5 of the regular coin chute 7 by a pivot pin 6, and a blocking gate 10 having a regular coin chute entrance blocking plate 9 extending in an arc shape from one end closes the regular coin chute entrance. It is pivotally connected to the side plate 11 of the regular coin chute 7 by a pivot pin 12 so as to be able to rotate between a position and an open position, and a locking gate operating engagement arm 8 is provided to protrude from the blocking gate 10 into the chute 7. The upper end engaging portion 1 of the micro switch operation prevention lever 4 is connected to the one end of the cutoff gate 10.
4 is provided in a protruding manner to urge the cutoff gate 10 to be always held at the fully open entrance position.

(Function) In the device of the present invention configured as described above, in the inactive state before a coin is inserted, the cutoff gate 10 is opened by the balance weight 13, which is a biasing means, as shown in FIG. position, the chute inlet 7a is opened, and the microswitch actuation prevention lever 4 is in a substantially vertical position due to the action of gravity, and the engaging portion 1 on the shutoff gate 10 is
5 is apart from the engaging portion 14 at the upper end of the micro-switch actuation lever 4, and the lower engaging portion 2 at the lower end of the micro-switch actuation prevention lever 4 is located below the actuating arm 1 of the micro-switch 20. Further, the locking gate operating locking arm 8 is located at a position where a coin entering the regular coin chute 7 from the chute entrance 7a can be locked (see FIG. 9).

Therefore, the wire inserted from the coin slot etc. passes through the entrance 7a of the regular coin chute 7, which is always open, and is connected to the operating arm 1 of the micro switch 20.
However, the micro switch actuating arm 1 can reach the micro switch actuating prevention lever 4.
Since the microswitch actuating arm 1 is prevented from moving downward by its engagement with the lower end engaging portion 2, the microswitch actuating arm 1 is not pushed down by the wire to be actuated.

However, when a regular coin falls into the chute 7 through the chute entrance 7a, the regular coin hits the locking gate actuating arm 8, which activates the shutoff gate 10, and the chute entrance 7a is closed by the shutoff gate 10. be done. When the cutoff gate 10 closes the chute entrance 7a, the hooking part 15 provided on the cutoff gate 10 engages with the hooking part 14 of the blocking lever 4, rotating the blocking lever 4 to the release position, and operating the micro switch. Arm 1 and blocking lever 4
is disengaged from the engaging portion 2, and the microswitch actuating arm 1 is actuated by a coin.

As described above, according to the present invention, the micro switch is not activated when the entrance 7a of the regular coin chute 7 is opened, and the cutoff gate 10 is activated by the coins entering the coin chute 7, thereby closing the entrance 7a. Since the microswitch is configured so that it can be operated in the state, unauthorized operation by a wire or the like can be completely prevented.

(Embodiment) The drawing shows one embodiment of the present invention, and the illustrated coin sorting device allows regular coins sorted from a coin input port 25 through a coin sorting passage to a regular coin chute 7.
The actuating arm 1 of the micro switch 20 passes through the chute 7 and protrudes into the chute 7 at the outlet at the lower end of the chute.
(See FIG. 8) is configured so that a regular coin passage signal is transmitted by pressing down and operating the coin.

In Figures 1, 2 and 6, reference numeral 4 denotes a micro-switch actuation blocking lever, which can be rotated between the actuation blocking position (see Fig. 1) and the open position (see Fig. 2) of the micro-switch arm. A hook is pivotally attached to the side plate 5 of the regular coin chute 7 by a pivot pin 6, and can be hooked to the lower side of the vertically bent arm of the operating arm 1 of the micro switch 20 in the normal position shown in FIGS. 1 and 6. 3 and 2, and in the normal position where the chute inlet 7a is open, the lower bent arm portion (see FIG. 8) located at the chute 7 of the actuating arm 1 is lowered by a wire or the like to open the micro It is configured to prevent switch 20 from being actuated.

A blocking gate 10 is installed on the side plate 5 of the regular coin chute 7.
As shown in FIG. An actuating engagement arm is provided by a screw 31 extending in an arc shape and engaging a slot 30 extending along the length of the main body of the blocking gate 10 at a position below the blocking plate 9. 8 is adjustably attached, and this operating engaging arm 8
extends from the main body of the cutoff gate 10 into the chute 7 so that regular coins falling into the chute 7 from the chute entrance 7a can be caught therein.

A balance weight 1 is attached to the main body of the cutoff gate 10.
3 is attached, and as a result, the inlet is normally held at the fully open position, but when a coin falling into the chute 7 engages with the engaging arm 8, the pivot pin 1
2, and both side edges of the blocking plate 9 are slidably guided in arcuate grooves 21 (only one of which is shown in FIG. 1) provided on both side plates at the chute entrance 7a. The blocking plate 9 is configured to be moved to the chute inlet fully closed position as shown by a solid line in FIG. 2 and by a phantom line in FIG. 9.

Therefore, as shown in Figure 9, regular coin A
When inserted from the coin input port 25, the regular coin A engages with both engaging pieces of the cradle 33 in a known manner, rides on the cradle 33, rotates, and is sent onto the inclined guide rail 48. While rolling on this inclined guide rail 48, the coin crosses the magnetic field of the coin material sorting magnet 49, falls from the exit end of the inclined guide rail 48 as shown by arrow A, and hits the lower sorting piece 50. The coin falls into the chute 7 through the chute entrance 7a and engages with an actuating engaging arm 8 protruding into the chute 7. As a result, the cutoff gate 10 is rotated around the pivot pin 12, and at the same time, the cutoff plate 9 begins to close the chute inlet 7a, and when the chute inlet 7a is closed by the cutoff plate 9, the main body of the cutoff gate 10 The engaging portion 15, such as a pin, protruding from the free end of the lever rotates the blocking lever to the release position as described later, whereby the genuine coin A depresses the switch actuating arm 1 to actuate the switch and exit from the outlet 7b. It will fall into the coin box below. Incidentally, when the fraudulent coin B of different material crosses the magnetic field of the coin material sorting magnet 49, it is subjected to a braking action as is known, and as shown by arrow B in FIG. 9, it falls and hits the sorting piece 50. It is returned to the return slot 27 via the return chute.

The blocking lever 4 has an engaging portion 14 at its upper end, which engages the inner surface of the blocking plate 9 in the open position to prevent the blocking plate 9 from rotating from the normal position shown in FIG. The terminal end portion is engaged with the engaging portion 15 on the blocking plate 9 to move the blocking lever 4 to its pivot pin 6.
It has an engaging part 16 that is rotated around the .

According to the above-described configuration, when the cutoff plate 9 of the cutoff gate 10 opens the entrance 7a of the regular coin chute 7, the microswitch operation prevention lever 4 is moved to the pivot pin 6 by a wire inserted from the coin input port. Even if an attempt is made to rotate the lever 4 around the stopper, the engagement between the engaging portion 14 and the blocking plate 9 will cause the blocking lever 4 to be rotated from the operation blocking position (see Figure 1) to the releasing position (see Figure 2). , and as long as the blocking lever 4 is located in the operation blocking position as described above,
Both ends 1a of the operating arm 1 of the micro switch 20,
1b cannot engage with the engaging portions 2 and 3 of the blocking lever 4 to operate the microswitch operating arm 1.

A condition in which the microswitch activation arm 1 can be activated occurs only when a regular coin passes into the regular coin chute 7. That is, the regular coin falls into the regular coin chute 7 and engages the operating engagement arm 8 of the cutoff gate 10, and the cutoff gate 10 is connected to the pivot pin 1.
2, the blocking plate 9 moves into the arcuate groove 21 (the arcuate groove on the side plate 5 is not shown) provided in the side plates 5 and 11 at the entrance 7a of the regular coin chute 7. The blocking lever 4 is rotated around the pivot pin 6 by the engagement of the engaging portions 15 and 16, and when the blocking plate 9 has completely closed the entrance 7a, the blocking lever 4 is rotated.
reaches the release position (see Figure 2). and,
In this release position of the blocking lever 4, the end 1b of the microswitch operating arm 1 can freely move into the slot 22 without being caught by the engaging part 3, and the other end 1a The coins can also move freely without being caught by the engaging part 2, so that the genuine coins can actuate the microswitch operating arm 1 and pass into the lower coil box.

As described above, the microswitch actuating arm 1 is in an operable state only when the blocking plate 9 completely blocks the entrance 7a of the regular coin chute 7, and in such a blocking state, not only the wire but also extremely thin tape It is not possible to insert even a shaped metal piece into the coin chute 7. Therefore, unauthorized operation of the microswitch by such an insert can be completely prevented.
