2. Description of the Related Art In a game arcade where a large number of medal gaming machines are installed, used medals are polished or washed and then supplied to the medal gaming machines. The method of polishing or cleaning the medals is 1) a method of polishing medals by using the adsorption of plastic particles called pellets, 2) a method of brushing medals in hot water, and 3) a parting of medals in a cleaning solution. There is a method of vibrating by a feeder to lift dirt. Of these methods, the general method 1) requires a special device for separating medals and pellets after polishing or cleaning because they are once mixed with pellets. In the methods 2) and 3), a large amount of liquid is used, so that the method is troublesome, and a drying step is required.
On the other hand, a method of polishing a ball with a cloth is known, and a method of applying the method to a medal has been proposed. For example, as disclosed in Japanese Unexamined Patent Publication No. Hei 8-19658 "Coin / ball polishing device", a pressing plate presses between two polishing cloths wound in a roll shape, and a medal is sent to this portion while being rotationally driven. Some are polished. This method requires a device for transferring medals one by one,
In addition, since a load (force) is applied to the medal, the medal may be easily damaged. On the other hand, there has been proposed a method of polishing medals by arranging two polishing cloths in parallel at an interval, passing a medal therebetween, and rubbing the medals against the polishing cloth. For example, in Japanese Patent Application Laid-Open No. 5-49750, two plates, each having an abrasive cloth laid on the opposing surface, are vertically and parallelly arranged so that the gap between the abrasive cloths is slightly larger than the thickness of the medal. In addition, the plates are relatively displaced in parallel (vertical direction) by the driving means, and while the medals inserted between the polishing pads are lowered by gravity through the gap, the plates are caused by the relative displacement of the two plates. A method of polishing or cleaning by sliding between a medal surface and a polishing surface is disclosed. In this method, a driving device for relatively displacing the plate in the vertical direction is required, and the gap needs to be adjusted, and a considerable load (force) is applied to the medal.
Was added, so that the medal was easily damaged.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a medal, coin, or ball (hereinafter referred to as a medal, etc.) is provided between two cloth-shaped polishing members arranged in parallel in the vertical direction from the top to the medal. This is a polishing device that throws in and drops from the lower end, and polishes or cleans medals etc. during that time, and the mechanical elements of the device can be simple, small and inexpensive, and there is a risk of damaging medals etc. No new medals
It is an object of the present invention to provide a MigakuSo location.

[Operation and effect of the means and the invention to solve the problems] or
First, the polishing method employed in the polishing apparatus of the present invention is described.
Will be explained. In this polishing method, an opposing cloth-like polishing member hung in a hanging state is attached to any of a medal, a coin, and a ball.
The object to be polished (hereinafter, these polishing objects
When an elephant is also referred to as a medal or the like) when it is thrown from above between the opposing cloth-like polishing members, the pressing force is large enough to separate the opposing cloth-like polishing members so that they can fall freely. The polishing object is polished by the cloth polishing member by freely falling between the opposing cloth polishing members.

[0005] This polishing method will be described with reference to FIGS. 1 and 4 showing the principle configuration thereof, and also to FIGS. 2 and 3 showing the basic configuration examples. According to this polishing method, as shown in FIG. 1, two opposed cloth-like polishing members 1 and 2 are suspended in a state of being suspended by gravity in a substantially stationary state, and both cloth-like polishing members 1 and 2 are suspended. A pressing force 3 is applied as uniformly as possible along the surface of the cloth-like polishing member in order to keep the two in contact with each other. The magnitude of the pressing force 3 is such that when a medal or the like is thrown between the cloth-like polishing members from the upper end side, the two cloth-like polishing members 1 and 2 are pushed apart, fall freely, and are stuck halfway. Not to be relatively small. Thus, the surface of the medal or the like 4 is polished or cleaned by free-falling the medal or the like 4 between the two cloth-like polishing members in contact with each other by the two cloth-like polishing members. As described above, except for using the pressing means for simply pressing the cloth-like polishing members 1 and 2 statically, there is no need to use a special device such as a driving device for the two cloth-like polishing members. The mechanical elements of the apparatus for implementing this method are simple, small and inexpensive to manufacture, and can be easily polished with gloss without damaging medals and the like. Further, the cloth-like polishing members 1 and 2 are not only hung down substantially vertically as shown in FIG. 1 and the medals and the like freely fall substantially vertically, but also, for example, as shown in FIG. 2 is hung down along the inclined surface 5a of the inclined surface providing body 5 which is inclined in a plane (the paper plane of FIG. 2) including the vertical line and orthogonal to the cloth-like polishing member surface, thereby reducing the pressing force. It can be added using the gravity of the cloth-like polishing member itself. That is, by using the inclined surface providing body 5 as a pressing means, the above pressing force can be obtained without providing any special pressing force applying device. The inclined surface may be a spirally descending inclined surface. In this case, the surface of the side of the medal or the like facing the inclined surface tends to be polished more often. However, by repeatedly and repeatedly inserting medals or the like, both surfaces are uniformly polished. Further, one of the cloth-like polishing members 1 of the cloth-like polishing members 1 and 2 which is vertically suspended as shown in FIG.
And a plurality of fluid bags 7 filled with a fluid, preferably a gas, more preferably adjusted to a substantially constant pressure from the cloth-like polishing member 2 at intervals, for example. It can be preferably used. Even when a large number of medals or the like are clogged between the cloth-shaped polishing members, the fluid bags 7 are eventually pushed away by the weight of the large number of medals and dropped at once, so that the clogging of the medals and the like is well prevented. Further, as shown in FIG. 4, a side wall providing body 8 for providing a side wall surface 8a of a fall passage for medals 4 is arranged along one edge of the width of the cloth-like polishing members 1 and 2 and the side wall providing body. 8 and the cloth-like polishing members 1 and 2
Is inclined toward the side wall providing body 8 in the plane including the cloth-like polishing member surface, so that the side surface of the medal etc. 4 has the inclined side wall surface 8a (necessary as shown in FIG. (A cloth-like polishing member is stuck on the side wall surface 8a in accordance with the above), so that the medals and the like are dropped while being in contact with the medals and the like, and the side surfaces of the medals and the like can be polished. The tips of the two cloth-like polishing members 1 and 2 which are suspended by gravity are completely free ends, and so that medals and the like do not stay while freely falling between the cloth-like polishing members 1 and 2. As far as possible, the end may be supplementarily pulled with a weight or pulled through a spring. or,
The opposing cloth-like polishing members 1 and 2 are not limited to the case where two independent cloth-type polishing members are used, and for example, two flat surfaces formed by crushing a long bag-shaped member into a flat shape are used. Or each of the opposed cloth-like polishing members 1 or 2 or 1 and 2 may be constituted by a plurality of cloth-like polishing members.
Further, a cleaning solution or an antibacterial agent can be dropped or impregnated on the cloth-like polishing members 1 and 2 to enhance the cleaning effect and the antibacterial effect when polishing medals and the like. Also, there is no limitation on the size of medals or the like to be polished or cleaned, and medals or the like of different sizes may be mixed if the thickness is almost constant, and the medals or the like themselves are pellet-shaped. It doesn't matter if it's a sphere or not.

[0006] The material of the cloth-like polishing members 1 and 2 is as follows.
For example, various woven fabrics such as cotton cloth, and in some cases, paper products, etc.
Any material can be used as long as it is soft and has a certain degree of strength and abrasion resistance like a general cloth. Among them, a cotton fabric which is soft and has a small amount of dust as the fluffy fiber is stretched as seen in a toweling fabric is particularly preferable.

Next, the polishing apparatus of the present invention will be described.

A polishing apparatus for polishing with a polishing member, wherein the pressing means is a zigzag bent insertion path providing body which provides an insertion path for passing the opposed cloth-shaped polishing member while bending the zigzag.

FIG. 2 shows how the cloth-like polishing members 1 and 2 are tilted.
As shown in the above, only the lower surface of a medal or the like that comes into contact with the inclined surface via the cloth-like polishing member 1 or 2 by simply inclining in one direction is cloth-like polishing with a greater pressure to which the own weight of the medal or the like itself is added. In order to come into contact with the member 1 or 2, it is necessary to drop freely between the cloth-like polishing members 1 and 2 several times at random so that both surfaces of medals and the like are evenly polished. In the polishing apparatus of the present invention, a zigzag bent insertion path providing body is used to change the direction of the cloth-shaped polishing members 1 and 2 in a zigzag manner and repeatedly incline. The cloth-like polishing member 1 or 2 comes into contact with a uniform contact pressure, so that both surfaces are uniformly polished.

According to a third aspect of the present invention, in the polishing apparatus for a medal or the like according to the second aspect , the zigzag bent insertion path providing body is used for passing the opposed cloth-like polishing member in a zigzag manner while bending it. The insertion passage is a ladder form body formed in a plurality of stages.

In the polishing apparatus for medals and the like according to the present invention, FIG.
Further, as shown as a more specific configuration example of the polishing apparatus, the zigzag of the cloth-like polishing members 1 and 2 at least once is formed by the ladder form frame 9 in which a plurality of stages of the insertion passages 9a and 9b are formed. It is formed. The ladder form body 9 in FIG. 5 is configured such that two cloth-like polishing members 1 and 2 formed by crushing a bag 10 made of a long cloth-like polishing member are passed through the insertion passages 9a and 9b. Gives a zigzag of times. As shown in FIG. 6A, when medals or the like are thrown into the cloth-like polishing members 1 and 2 provided by the bag 10 made of a zig-zag cloth-like polishing member that is vertically suspended as a whole, as shown in FIG. First, as shown in FIG. 6 (b), one surface of a medal or the like is first mainly polished by the cloth-like polishing member 1 in the obliquely downward insertion passage 9a, and then as shown in FIG. 6 (c). In the next return, the opposite surface starts to touch the cloth-like polishing member 2 while heading toward the obliquely downward insertion passage 9b.
After the opposite surface of the medal or the like in the return insertion passage 9b is mainly polished by the cloth-like polishing member 2 as shown in (d), as shown in FIG. It is discharged from below the polishing members 1 and 2. By laminating the ladder form frames 9 vertically, a ladder form body that gives the cloth-like polishing members 1 and 2 a large number of zigzag bends can be obtained. FIG. 7 exemplifies the ladder form body 11 configured so as to provide a large number of zigzags to the cloth-like polishing members 1 and 2. The ladder form member 11 includes cloth-like polishing members 1 and 2.
Are inserted in a zigzag manner and are repeatedly provided in multiple stages. The ladder form 11 is divided into two parts by a surface 12 and each part is freely opened and closed by a hinge (not shown).
By sandwiching (in this case, the bag 10 of a long cloth-like polishing member) and closing it, two opposite cloth-like polishing members 1 and 2 which are bent in a large number of zigzags at a time can be obtained. In addition, as a ladder-type frame body for forming the cloth-like polishing members 1 and 2 having a large number of zigzag bends, the cloth-like polishing members 1 and 2 are repeatedly zigzag in the longitudinal direction of a long rectangular plate. As an insertion passage for passing
It may be one in which a large number of window holes (holes perpendicular to the surface of the plate) having a quadrangular cross section are formed at intervals.

In the description based on the above figures,
Although the hanging ends of the two cloth-like polishing members 1 and 2 are shown as free ends, for example, as shown in FIG. 8, the cloth-like polishing members 1 and 2 are substantially in a stationary state. The cloth-like polishing members 1 and 2 are not wound,
It is also possible to wind up the winding cores 15 and 16d little by little from 3 and 14 so as to save the trouble of replacing the cloth-like polishing member. However, at this time, the cloth-like polishing members 1 and 2 are pulled so strongly by the winding materials 13 and 14 that the pressing force becomes excessively large so that medals and the like do not stay between the cloth-like polishing members.

According to a fourth aspect of the present invention, in the polishing apparatus for a medal or the like according to the second aspect , the zigzag bent insertion path providing body includes two elastically flexible belts bent in a zigzag manner. A zigzag insertion path is formed between the two belts by arranging them in parallel at an interval.

In the polishing apparatus for medals and the like according to the present invention, two belts having elastic flexibility are similarly bent in a zigzag manner and are arranged in parallel at an interval from each other, so that two opposing cloths are provided. Since the insertion passages through which the abrasive members 1 and 2 pass are formed, medals and the like are stagnated while the medals and the like fall between the cloth-like abrasive members bent in a zigzag pattern, and a plurality of medals and the like are gathered. However, since the belt flexes due to the gravity of medals or the like and retreats, and the medals or the like that have gathered are discharged at a stroke, a zigzag bent insertion passage providing body in which clogging of medals and the like is unlikely to occur is obtained.

A polishing apparatus according to a fifth aspect of the present invention is the polishing apparatus for medals or the like according to any one of the first to fourth aspects, wherein at least one of the widths of the cloth-like polishing members facing each other is adjusted. A side wall member which forms a side wall surface of a free fall passage for medals or the like is provided so as to limit the hanging direction of the opposing cloth-like polishing member as a whole in a plane including the surface of the cloth-like polishing member. In this case, the partition wall is inclined to the side where the partition member is located.

In the polishing apparatus for medals and the like according to the present invention, as shown in FIG. 4, the medals and the like inserted between the two cloth-like polishing members are free-falling in the fall passage while the side wall member of the fall passage is provided. The medals and the like are rotated and their side surfaces are polished evenly because the medals and the like are made to fall while being in contact with the side wall surfaces.
