Description

  The present invention relates to a game media polishing apparatus for polishing game media such as pachinko balls and coins with an abrasive cloth.

  Japanese Unexamined Patent Publication No. 2000-254333 discloses a ball polishing apparatus having a polishing cloth winding mechanism. In this ball polishing apparatus, an endless rotating belt is stretched between rotating rollers at the upper and lower ends of the mounting base. A guide rail 31 is provided to face the rotating belt, and an end-like polishing cloth is stretched so as to cover the surface of the guide rail. The pachinko balls are lifted and polished while being pressed against the polishing cloth on the surface of the guide rail by the rotating belt. The polishing cloth is set in a roll shape on the discharging shaft of the polishing cloth roll before use, drawn downward by a driving rotary roller, and finally wound intermittently on the winding shaft.

The polishing apparatus requires a space for mounting a roll-shaped polishing cloth on the side of the payout shaft, and requires a space for winding the polishing cloth in the form of a roll on the winding shaft side. . In addition, the winding diameter is small at the beginning of winding, and the roll diameter on the winding shaft grows greatly, whereas the roll diameter on the dispensing side is large and the reduction of the roll diameter on the dispensing shaft is small. Therefore, in order to achieve smooth winding while balancing this growth and shrinkage, it is not sufficient to separate the two shafts by the roll radius, and it is necessary to separate them more than that. As described above, the conventional polishing apparatus has a problem that a large space is required to wind up the polishing cloth, and the polishing apparatus is increased in size.
JP 2000-254333 A (FIG. 1)

  The present invention has been made in order to solve the above-described conventional problems and to provide a game media polishing apparatus capable of reducing the size of the polishing cloth by reducing the winding space of the polishing cloth.

  The game media polishing apparatus of the present invention made to solve the above-mentioned problems comprises a payout shaft for mounting a polishing cloth before polishing use, and a take-up shaft for winding the polishing cloth after polishing use, and paying out In a game media polishing apparatus that polishes a game medium by a polishing portion provided between a shaft and a winding shaft, it corresponds to the winding amount of the polishing cloth that is wound and grown on the winding shaft of the polishing cloth. Thus, a moving mechanism for sliding the take-up shaft in the direction of the payout shaft is provided. The moving mechanism includes a driving roller that rotates the winding shaft via a polishing cloth wound around the winding shaft, and a support base that slidably supports the winding shaft between the driving roller and the discharge shaft. And an elastic body that urges the take-up shaft in the direction of the drive roller. Further, it is desirable that the winding shaft at the start of winding is separated at least by the initial roll diameter of the polishing cloth from the dispensing shaft.

  In the game media polishing apparatus of the present invention, the winding shaft of the polishing cloth is slid in the direction of the payout shaft in response to the growth of the roll diameter of the polishing cloth. The take-up space can be narrowed. Since the moving mechanism is composed of a driving roller, a support base that slidably supports the winding shaft between the driving roller and the discharge shaft, and an elastic body that biases the winding shaft in the direction of the driving roller. The winding shaft can be rotated in contact with the driving roller through the polishing cloth, and the polishing cloth that is wound up and grows against the bias of the elastic body can be slid in the direction of the discharge shaft. it can. Further, the winding shaft at the start of winding is separated from the discharging shaft by the initial roll diameter of the polishing cloth, so that the winding shaft is moved to an intermediate position between the driving roller and the discharging shaft after winding, so that one polishing cloth is used. Rolls can be accommodated between them.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1 and 2 are diagrams showing a game media polishing apparatus according to the present invention, wherein 1 is a support for the polishing apparatus and 2 is a polishing rail. A polishing cloth discharge shaft 3 is fixed horizontally on the support stand 1, and a roll-shaped polishing cloth 4 before use is mounted on the discharge shaft 3. In addition, a driving roller 5 rotated by a motor M and a winding shaft 6 of the polishing pad 4 are provided on the support base 1 in parallel in the horizontal direction. The take-up shaft 6 is inserted into a horizontally long hole 7 formed between the drive roller 5 and the payout shaft 3, and the take-up shaft 6 is positioned on one line with the drive roller 5 and the payout shaft 3 and slides. Can move. The take-up shaft 6 is rotatably held by a bearing 8. Since the bearing 8 is urged by the coil spring 9 in the direction opposite to the payout shaft 3, the take-up shaft 6 is also urged integrally and is in contact with the drive roller 5. The drive roller 5 has a large number of protrusions on the roller surface, and these protrusions bite into the polishing pad 4, so that the polishing pad 4 can be wound more reliably.

  The polishing cloth 4 attached to the payout shaft 3 is wound around the winding shaft 6 via the guide roller 11, the polishing rail 2, and the guide roller 12, but the winding shaft 6 is in a state before starting winding. The abrasive cloth 4 is separated from the delivery shaft 3 by the roll diameter. Therefore, the polishing pad 4 can be smoothly wound up sufficiently in response to the rapid growth of the roll diameter at the start of winding.

  Since the polishing cloth 4 is rubbed against game media such as pachinko balls and coins conveyed by screws, belts, etc. on the polishing rail 2, these game media can be polished. As the polishing progresses, the polishing cloth 4 is contaminated with oil, dust, etc., and the polishing ability is lowered. Therefore, the polishing cloth 4 has a predetermined length with an appropriate time interval by a intermittent winder (not shown). 4 is wound around the winding shaft 6.

  Since the winding shaft 6 is brought into contact with the driving roller 5 through the polishing pad 4 by the bias of the coil spring 9, the winding shaft 6 is rotated by rotating the driving roller 5 by the motor M. Since the roll diameter of the polishing cloth 4 wound up grows as the winding shaft 6 rotates, the winding shaft 6 slides in the direction of the payout shaft 3 against the bias of the coil spring 9.

  When the polishing cloth 4 is used and the winding is completed as shown in FIG. 3, the polishing cloth 4 grown to the same extent as the roll diameter before the start of use is located between the drive roller 5 and the discharge shaft 3. Will be intervened. That is, the winding shaft 6 is slid to the intermediate position between the drive roller 5 and the payout shaft 3, so that the winding space can be saved by the radius of the initial roll.

  As described above, the game media polishing apparatus according to the present invention is configured to slide the winding shaft toward the payout shaft in accordance with the roll diameter of the growing polishing cloth. Half of the diameter can be saved, and the polishing apparatus can be downsized accordingly.

It is a front view of the polish device of the present invention before the polishing cloth starts winding. It is a top view which shows the structure of the grinding | polishing apparatus of this invention. It is a front view of the polish device of the present invention which the polishing cloth completed winding.
