DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail by embodiments of the present invention with reference to the drawings. First Embodiment FIGS. 1 and 2 show an overall view of a hoisting and polishing apparatus according to the present invention provided at, for example, a central portion or an end of an island of a coin (medal) game machine. A polishing guide member 2 forming a conveyance guide path in a vertical housing 1;
2. In the embodiment, groups are provided in series. Each of the polishing guide members 2, 2,... Has a guide groove formed along the height direction, and they are connected to each other.

In the housing 1, an endless conveyor belt 4 made of, for example, cloth or rubber is provided so as to face a guide path formed by the polishing guide members 2, 2,.... .

The conveyor belt 4 has a driven pulley 5 on the upper end side.
And a main pulley 6 on the lower end side. The drive motor 7 has its output shaft and drive belt 8
, The main pulley 6 is rotated, whereby the conveyor belt 4 is conveyed along an endless trajectory.

After passing through the coin-operated game machine, the collected and dirty coins Mi are introduced into the alignment inlet 9, and the polishing guide member 2 (specifically, its guide groove) whose structure will be described later.
In the process of pressing the outer peripheral surface of the coin M by the relative resilience of the guide groove bottom and the conveyor belt 4 during the pressing between the guide groove bottom and the conveyor belt 4, the two uneven planes of the coin M are cleaned on both sides of the guide groove The dirt is scraped off by the modified surface and polished, and is lifted upward by the conveying force of the conveying belt 4. Thus, the coin M polished by the polishing guide members 2, 2,.
o is discharged from the outlet 10.

Reference numeral 1A denotes a main structural member. The detachable metal fitting 1B is detached, the housing 1 is detached, and the inside of the housing 1 is disassembled or facilitated when necessary. When the housing 1 is removed, the transport belt 4
Is exposed.

In such a lifting process, in order to reliably guide the conveyor belt 4 and to ensure that the coin M is pressed against the guide groove of the polishing guide member 2, the distance between the driven pulley 5 and the main pulley 6 is increased. On the way, guide rolls 11, 11... That rotate freely at intervals in the height direction are provided.

As shown in FIG. 3, for example, the guide roll 11 is formed by forming circumferential grooves 11a, 11a,... Formed on the outer peripheral surface of a cylindrical roll at intervals in the generatrix direction. Can be used. Grooves 11a, 11a
.. Correspond to the formation positions of the guide grooves of the polishing guide member 2 described later, as shown in FIG.

Although not shown, a concave groove can be formed in the main pulley 6, the driven pulley 5, and the like, or in one of these cylindrical rotating bodies, in addition to the guide roll 11. It is preferable that the concave groove is formed at least in the main pulley 6 and each guide roll 11 group.

As shown in FIG. 4 and FIG.
a, 11a..., the coins M
, And the coin M is resiliently pressed by the tension of the conveyor belt 4. As a result, the coin M becomes the polishing guide member 2.
Is pressed against the bottom of the guide groove, so that the coin M is securely pressed against the guide groove.

The use of the guide roll 11 makes it possible to reliably transport the coin M and press against the guide groove of the polishing guide member 2 without applying excessive tension to the transport belt 4. As a result, there is also an advantage that the life of the transport belt 4 is extended.

The entrance width W of the concave groove 11a is preferably 5 to 18 mm, particularly preferably slightly larger than the diameter of the coin M, for example, about 12 mm. The depth D is preferably about 1 to 5 mm.

As the polishing guide member 2, the one shown in FIG. 5 can be used. In this example, eight rows of gutter grooves 2A, 2A... Along the lifting direction are formed in the width direction, and abrasive layers 20, 20,... Are formed in each of the gutter grooves 2A, 2A. In this example, the inner surface of the abrasive layer 20 forms the guide groove 20A of the present invention.

The guide groove 20A is formed so that the coin M
It has a groove width equal to or slightly larger than the thickness of the coin M, and its depth can be selected depending on the diameter of the coin to be handled.
8) It is preferably φ.

The polishing guide member 2 has long supporting pieces 22, 23 and 24 with long legs formed on the back surface thereof along the lifting direction at both sides and the center, respectively, and is fixed in the housing 1.

In the device configured as described above, after passing through the coin game machine, the collected and dirty coins Mi are collected.
Is introduced between the guide groove 20A, which is a groove surface formed by the abrasive layer 20 of the polishing guide member 2, and the conveyor belt 4, and the bottom of the guide groove 20A and the conveyor belt 4
In the process of pressing the outer peripheral surface of the coin M by the relative resilient pressure, the transport belt 4 moves, and the coin M is forcibly rolled and lifted.

In this process, the two planes of the coin M are the cleaning surfaces (the guide grooves 20) on both sides of the guide groove 20A.
(The groove surface of A), the coin M is lifted up by the conveying force of the conveying belt 4 while the dirt on the two flat surfaces of the coin M is scraped off and polished by the cleaning surface. Is done. Thus, the coin Mo polished by the polishing guide members 2, 2,... Is discharged from the outlet 10 while being transported by the transport belt 4. The discharged clean coin Mo is supplied to the coin gaming machine.

In the polishing method according to the present invention, in the process in which the coin M moves on the cleaning surface while rolling, each point of the deviated plane of the coin M forms a "normal cycloid curve" corresponding to the radial position. Because these curves intersect, the polishing effect is significantly greater than simply moving, for example, linearly (without rolling) between opposing sandwiching belts.

(Second Embodiment) In the first embodiment, the polishing guide member 2 is used.
The guide groove 20A is formed by forming a gutter groove 2A in the gutter groove 2A and the abrasive layer 20 in the gutter groove 2A, but the polishing guide member 2 is made of a material having a grinding ability for the coin M. In the case of having polishing ability by itself such as having fine irregularities, a guide groove may be simply formed.

(Others) Although the above example is an example of a lifting and polishing apparatus, it is not necessary to have a lifting function. Examples of the material constituting the abrasive layer or the cleaning surface exhibiting abrasiveness include various plastics,
Known abrasive materials such as buffs, cloths, non-woven fabrics, leathers, rubbers, and composite materials thereof, and those obtained by mixing these particles can be used.

( Embodiment of Reference ) Abrasiveness can be imparted also at the bottom of the guide groove. However, as shown in FIG. 6, the abrasive layer 20 is formed only on the uneven plane (front and back) of the coin M. Is also good. Further, as shown, coins M can be fed in a single row.

In the present invention, at least the rolling means for rolling the game coin by the movement of the transport belt while pressing the outer edge surface of the game coin to the other side by the transport belt, and the rolling means In the rolling process of gaming coins,
There is provided cleaning means disposed opposite to the two planes of the gaming coin to contact the two planes of the gaming coin to clean the plane . As shown in FIG. 7 , the gaming coin M
Rolling means for rolling the game coins M by the movement of the conveyor belt 4 while pressing the outer edge surface of the game coin toward the receiving seat 200 by the conveyor belt 4, and the rolling of the game coins M by the rolling means. In the moving process, a pair of cleaning means around which an endless belt 20 exhibiting abrasiveness is wound is provided opposite to both the flat surfaces of the game coin M, and the endless belt 20 is placed on both sides of the game coin M. The flat surface can be cleaned by contacting the flat surface.

In this case, the endless belt 20 is stationary, and is moved by the driving force of a drive motor (not shown) in the direction opposite to the rolling direction of the game coin M by the transport belt 4 so that the endless belt 20 and the game The relative speed of contact with the coin M per unit time can be increased. For this,
The guide roll 201 of the endless belt 20 can be freely rotated.

[0038]

As described above, according to the present invention, the coin is brought into sliding contact with the abrasive cleaning surface while rolling.
It has excellent cleaning and polishing effects, and also has a large cleaning (polishing) throughput per unit time. Further, when a game coin is supplied to a gaming machine, there is provided an advantage that an abrasive function is provided to the coin lifting machine, thereby reducing the installation space.
