Abstract

PURPOSE:To provide the simplified and low-priced cleaning device to be interlocked with a game machine without requiring various kinds of additional devices by arranging grinding cloth with a small gap between parallelly with a conveyer for conveying a prize winning medium above this conveyer when cleaning the prize winning medium of the game machine. CONSTITUTION:The prize winning media of the game machine such as coins 2, for example, are moved from a collector to a conveyer 1 and conveyed one by one. Besides, grinding cloth 3 is arranged above the conveyer 1 with the small gap between parallelly to this conveyer 1. Further, the grinding cloth 3 is moved while being wound between a pair of pulleys 4, and pressed with the coin 2 on a pressing board 5 arranged on its upper surface. At such a time, the pressing board 5 is horizontally vibrated so that the grinding cloth 3 can be also vibrated to grind the one side of the coin 2. Successively, the coin 2 which one side is ground is dropped from the end terminal of the conveyer 1 through an internal passage 7 of a moving pipe 6 and moved onto another conveyer 8. Then, the other side of the coin 2 is ground by the similar operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cleaning dirty winning media used in a game machine.
This device is a device that is usually attached to a gaming machine.

[0002]

2. Description of the Related Art A conventional winning medium cleaning technique for a gaming machine will be described with reference to the drawings. FIG. 4 shows a method of cleaning a winning medium, which is a member to be cleaned, by mixing it with resin pellets and stirring. FIG. 5 shows a method of immersing the winning medium in a cleaning liquid layer for cleaning. The above cleaning techniques are generally put into practical use.

[0003]

However, the conventional cleaning method as described above is a so-called batch operation,
It is unsuitable for operating in conjunction with a gaming machine.
A special device (not shown) was required to interlock with the game machine. Further, in the conventional cleaning method, another device (not shown) is required for separating the member to be cleaned from the pellets or the cleaning liquid used as the cleaning medium. As described above, the conventional cleaning method requires a large number of additional devices and has a heavy cost burden.

[0004]

The present invention solves the above problems and does not require an additional device such as a device for separating a member to be cleaned from a cleaning liquid or pellets, or a device for interlocking with a gaming machine. It is therefore an object of the present invention to provide a winning medium cleaning device with a low cost burden. In order to achieve such an object, a device for cleaning a winning medium of a gaming machine, wherein a polishing cloth is installed above a carrier conveyor in parallel with the carrier conveyor with a small gap therebetween. Invented

[0005]

The winning medium cleaning device of the present invention is operated in conjunction with the game machine. The winning medium collected by the winning medium collecting device of the gaming machine is transferred onto the carrying conveyor of the device of the present invention, and is cleaned by a polishing cloth installed in parallel with a small gap above during carrying.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view of a winning medium cleaning device in which the winning medium is a coin, FIG. 2 is a front view of a winning medium cleaning device in which the winning medium is a hard ball, and FIG. 3 is a conveyer conveyor of the winning medium cleaning device in which the winning medium is a hard ball. FIG. When the winning medium is a coin, the coins 1 collected by the coin collecting device of the gaming machine are transferred onto the carrying conveyor 2 of the device of the present invention as shown in FIG. 1 and carried one by one. A polishing cloth 3 is installed above the transfer conveyor 2 in parallel with the transfer conveyor via a small gap. The polishing cloth 3 is replaced with a new surface by a pulley 4 as needed. A pressing plate 5 is installed on the upper surface of the polishing cloth 3, and the pressing cloth 5 presses the polishing cloth 3 against the coin 1. Further, since the pressing plate 5 vibrates in the horizontal direction by a vibrating device (not shown), the polishing cloth 3
Also vibrates with this and polishes the coin. As described above, one side of the coin 1 is cleaned by the vibration of the polishing cloth 3 while being conveyed by the conveyor 2, but the other side is not cleaned. Therefore, a mechanism was added to flip coin 1 and polish the other side.

A coin 1 whose one side is polished is a conveyor 2
From the end of the, through the passage 7 in the transfer pipe (6), dropped, and placed on another transport conveyor 8 in the inverted state,
The other surface is polished by the same mechanism as described above.
In order to ensure this reversal, the diameter of the passage 7 is formed to be larger than the thickness of the coin 1 and smaller than the outer diameter dimension. In this way, the other side of the coin is polished by the polishing cloth 10 by the vibration of the pressing plate 9 during the transportation on the transportation conveyor 8, and the cleaning of both sides is completed.

Next, the case where the winning medium is hard balls will be described. FIG. 2 shows a winning medium cleaning device when the winning medium is a hard ball. The hard spheres 11 collected by the hard sphere collecting device of the game machine are transferred onto the conveyor 12 of the device of the present invention, and are cleaned by the polishing cloth 13 during the conveyance. A pressing plate 14 is installed on the back surface of the polishing cloth 13.
The polishing cloth 13 is pressed against the hard balls 11 by 4. Also,
Since the pressing plate 14 vibrates in the horizontal direction by a vibrating device (not shown), the polishing cloth 13 also vibrates accordingly and polishes up the hard ball. The above mechanism is the same as that of the coin. However, in the case of coins, the flat surface in the fixed state may be polished, whereas in the case of hard spheres, the spherical surface must be polished evenly. The above mechanism only rolls in one direction during conveyance, and only the substantially fixed rolling direction is polished. Therefore, as means for arbitrarily setting the rolling direction, a plurality of guiding projections 15 having different directions are formed on the surface of the conveyor 12 as shown in FIG. 3 so that the rolling direction is arbitrarily changed. A recess may be formed instead of the protrusion. In this way, the surface of the hard sphere 11 can be polished all over. In addition, the protrusions and recesses are formed on the conveyor 1
The same effect can be obtained by forming the pressing plate 14 instead of the above two.

[0009]

According to the winning medium cleaning device of the present invention, it is possible to obtain a winning medium cleaning device that works in conjunction with a gaming machine, without requiring a number of additional devices. Therefore, the device becomes simple and the cost burden can be reduced.
