Description

[Detailed description of the invention] (Industrial application field) This invention relates to a coin sorting device installed in the coin insertion port of a vending machine, game machine, etc., and in particular to an improvement to prevent unauthorized operation of a coin sorting device equipped with a material checking magnetic device that has a magnetic braking action on coins rolling on a ramp in a coin sorting passage so as to be able to sort the material of the coins.

Conventional coin sorting devices of this type include a coin sorting passage limited between two parallel spaced side plates, and a coin sorting passage limited between two parallel side plates, as described in Japanese Patent Application Laid-Open No. 55-157085. A ramp for rolling coins through the passage, a material check magnetic device provided to provide a magnetic braking effect to the coins rolling on the ramp, and a magnetic braking device provided by the material check magnetic device. A coin chute whose entrance is located in the coin passing track downstream of the coin sorting passage exit for proper coins, which is less affected by the effects of and a coin sorting piece provided at a branch point from the exit of the coin sorting passage to the coin chute and the return chute, and the coin sorting piece is configured to move the coin sorting piece in a direction that increases the inclination of the ramp. When the coin sorting device is tilted, it is moved from the normal sorting position toward the entrance side of the coin chute, so that when coins are inserted, one end of the game machine, etc. is lifted and the coin sorting device is tilted to its normal vertical position. By sloping the road in a direction that increases its slope, the slope of the slope increases and the coins rolling on it are accelerated, thereby affecting the braking action on the coins, thereby increasing the slope of the slope. Although the correct coin advances to the coin chute through the same passage route as the correct coin, the coin sorting piece moves toward the entrance of the coin chute and blocks the entrance of the coin chute, so that the incorrect coin does not enter the coin chute. There are known devices designed to prevent the passage of such objects.

(Problem to be solved by the invention) However, as described above, when the coin sorting device is tilted in the direction where the slope of the ramp is increased, the coin sorting piece moves from the normal sorting position toward the coin chute entrance. In a structure that prevents illegal coins from passing through the coin chute by movement using a pendulum movement, etc., when a fraudulent act is committed by tilting the coin sorting device, the tilting movement of the coin sorting device and the sorting piece are prevented. Due to the time lag with the left and right movement of the coins, the sorting piece cannot provide a reliable blocking effect, resulting in a problem in that unsuitable coins end up passing into the coin chute.

In view of the above-mentioned problems, the present invention has been developed so that no matter how the coin sorting device is tilted by any tilting operation, the coin sorting device is tilted in a direction that increases the inclination of the ramp, and at the same time the stopper piece is adjusted to its normal position. It is intended to be able to instantaneously protrude into the passage of coins and prevent any coins from passing into the coin chute.

(Means for Solving the Problems) According to the present invention, there is a coin sorting passage limited between two parallel side plates, and a coin sorting passage for rolling coins to pass through the coin sorting passage. a ramp, a material check magnetic device provided to provide a magnetic braking effect to coins rolling on the ramp, and a coin sorting passageway exit for suitable coins that are less affected by the magnetic braking effect by the material check magnetic device. A coin sorting device comprising: a coin chute having an entrance located within a downstream coin passing track; and a return chute communicating with an outlet of a coin sorting passage for receiving incorrect coins that have been significantly subjected to magnetic braking action by a material checking magnetic device. A tilted stopper having a stopper piece protruding from one side of a main body having a balance weight portion is swingably pivoted to one side of a proper coin passage path extending from the ramp to the entrance of the coin chute. When the sorting device is not tilted, the stopper piece is oriented toward the exit of the coin sorting passage outside the proper coin passing track, so that when the coin sorting device is tilted in a direction that increases the slope of the ramp, the stopper piece is characterized in that it protrudes into the passage trajectory of the appropriate coin.

(Function) According to the present invention, when the coin sorting device is tilted in a direction that increases the slope of the ramp, the stopper piece immediately protrudes into the proper coin passing track, so that the coin sorting device can be used on a ramp that is highly inclined. When the incorrect coins are accelerated and pass from the exit end of the coin sorting path to the correct coin passing track, they collide with the stopper piece, which changes the direction of travel toward the return path and returns the coins, allowing them to pass through the coin chute. can be reliably prevented.

(Example) An embodiment of the present invention will be described with reference to the drawings.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a diagram showing an example of a coin sorting device provided with an inclined stopper according to the present invention, in which 1 is a top plate, 2 is a coin slot, 3 is a rigid lever, and 4 is a coin sorting device.
5 is a return port, 5 is a fixed side plate, 6 is a movable side plate whose upper edge is hinged to the fixed side plate 5 by an elastic connecting piece 7, and 8 is a coin sorting passage limited between both side plates 5 and 6. a magnetic device for checking the material of coins by applying magnetic braking to the coins rolling on the ramp;
The pin 16 is installed so that the sorting piece 15 at the lower end is located at the path branching point between the entrance 12 to the proper coin chute 11 and the entrance 14 to the incorrect coin return chute 13.
a pendulum lever whose upper end is pivotally connected to the fixed side plate 5 and swingably hangs; 17 is a distribution piece 15;
A window 18 provided in the stationary side plate 5 to allow the coin to protrude to the passage branch point indicates a proper coin detection micro switch provided at the lower end outlet 19 of the proper coin chute 11.

FIG. 2 shows an inclined stopper 20 according to the present invention, the inclined stopper main body 21 has a balance weight part 22, and one end of a plate-shaped stopper piece 24 is inserted into a stopper mounting slot 23 of the main body 21 with a wedge piece 25.
The plate-shaped stopper piece 24 has a width approximately equal to the width of the coin sorting passage and projects from the main body 21 to one side.

This inclined stopper 20 is attached to a pivot pin 26 on the stationary side plate 5 through a mounting hole 25' from the ramp 9 to the entrance 1 of the coin chute 11, as shown in FIG.
It is located on one side of the passage track 28 for the proper coins 27 up to the number 2, and is pivotally mounted so as to be swingable. In this case, it is preferable to select a position such that the tip 24a of the stopper piece 24 is just above the proper coin passing trajectory.

Next, the operation of the inclined stopper having the above-described structure will be explained. When the coin sorting device is tilted backwards as shown in FIG.
The tip 24a is connected to the coin chute 11 from the ramp 29.

(Effects of the invention) According to the invention, when the coin sorting device is tilted backward so that the slope of the ramp is increased, the stopper can plunge into the passage trajectory of coins from the ramp to the coin chute entrance. Since the tilt stopper, which is protruded from the main body with a balance weight, is pivotally attached to the piece, it is possible to reliably prevent unauthorized use due to the tilt with an extremely simple means.
