Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a polishing device for pachinko balls.

BACKGROUND ART Conventionally, in order to purify pachinko balls as game balls with dust, finger marks, etc. attached thereto, a polishing device has been used that polishes the pachinko balls by stirring the pachinko balls and an abrasive material. In such a pachinko ball polishing device, when a predetermined amount of pachinko balls are polished, the surface of the abrasive becomes dirty and the cleaning effect becomes weak. For this reason, the abrasive material has been taken out periodically and cleaned with detergent or the like. However, there have been complaints that cleaning such abrasive materials is time-consuming.

The present invention was made in view of the drawbacks of the prior art, and its purpose is to provide a game ball polishing device that regenerates the abrasive by scraping the surface layer of the abrasive.

The present invention will be described with reference to embodiments shown in the drawings. FIG. 1 shows an apparatus for polishing game balls, in which 1 indicates a pachinko ball as a game ball, and 2 indicates an abrasive material such as a synthetic resin granule. 3 is a polishing machine that polishes the pachinko ball 1 by stirring the pachinko ball 1 taken in from the pachinko ball intake port described later and the abrasive material 2 taken in from the abrasive material intake port described later; 4 is the polished pachinko ball Separators 5 and 5 for separating the abrasive material 2 from the abrasive material 2 are an abrasive transport path that returns the separated abrasive material 2 to the abrasive intake port, and 6 is an abrasive regenerating machine inserted in the middle of the transport path 5. shows. The polishing machine 3 has a tube body 7 curved downward into a substantially arc shape, a motor 8 attached to the upper end of the tube body 7, and a motor 8 connected to the rotating shaft of the motor 8, and inserted along the tube body 7. It is generally composed of a spiral body 9. A pachinko ball intake port 11 for taking in pachinko balls 1 sent from the out rail 10 and an abrasive material intake port 12 for taking in the abrasive material 2 sent from the transport path 5 are bored near the lower end of the pipe body 7. An outlet port 13 is provided near the upper end of the tube body 7. The sanding machine 3 is therefore
The pachinko ball 1 and abrasive material 2 introduced into the motor 8
The material can be stirred and transported from below to above by a spiral body 9vc driven by a spiral body 9vc. Further, the separator 4 has a sieve 14 having an interval slightly smaller than the diameter of the pachinko balls 1, and the mixture of the pachinko balls 1 and the abrasive material 2 passes through the sieve 14.
4, the separator 4 causes the abrasive material 2 to fall downward, allowing only the pachinko balls 1 to be sent to the gutter 15.

Next, the regenerator 6 will be explained in detail using FIG. 2. 1 in the diagram
Reference numeral 6 denotes a cutting machine that scrapes off the surface layer of the abrasive material 2, 17 a sorter that separates the abrasive material 2 from the scraped shavings, and 18 a collector that collects the shavings. The cutting machine 16 has a container 19 that opens into the transport paths 5, 5 and the sorter 17, and the container 1.
9 and a vane rotating body 21.21 rotated by a motor 20. The sorting machine 17 is composed of, for example, a container 22 and a sawtooth fan 23 housed in the container 22 and rotated by a motor 20, and sucks only the shavings of the abrasive material 2 by generating an air flow. . As shown in FIG. 3, the collector 18 has a container 2 (
i, a mower 27 provided on the side wall of the container 26, and a screw fixed to the rotating shaft of the motor 27 for stirring the sol or liquid 28 (for example, water) in the container 26. It is composed of a body 29. Therefore, the collector 18 transfers the air containing shavings from the sorter 17 to the inlet 2.
4 and collides with the liquid 28 in the collector 18, whereby the shavings are absorbed into the liquid and fresh air is discharged from the outlet 25. Note that 30 is an abrasive material supply port for supplying new abrasive material 2.

The game ball polishing device according to the present embodiment has the above-described configuration, in which the abrasive material 2 whose surface has been soiled by the balls 1 in the polisher 3 is separated by the separator 4, and the transport path 5 It is guided to the regenerator 6 via the . In the regenerator 6, the abrasive material 2 obtains a fresh surface and is again led to the sander 3.

In addition, since air flow is generated in the ladle machine 6 as shown by the arrow, the regenerator 6 also purifies the air in the game hall.

In this embodiment, the polishing machine 3 is described as using the spiral body 9, but it may be of other types such as a screw type. Furthermore, although the cutting machine 16 has been described as using the vane rotating body 21, it may also be one in which a disk or the like is provided with file-like teeth. Furthermore, although the collector 18 has been described as one that uses water or the like, it is of course possible to use a filter type that uses fibers, a Ushitake filter type, and one that uses water or the like. be.

The present invention has been described in detail above, and includes a cutting machine that scrapes off the surface layer of the abrasive material in the middle of the abrasive transport path, a sorting machine that separates the abrasive material from the scraped off swarf, and a separator that separates the shavings from the abrasive material. Since an abrasive regenerating machine consisting of a collection device and a collector is inserted, dust, hand grime, etc. adhering to the surface of the abrasive are removed along with the scraped surface layer of the abrasive, and the surface of the abrasive is always fresh. Therefore, the cleaning power of the abrasive can be maintained. Furthermore, since the sorting machine is designed to suck only the shavings of the abrasive material by generating an air flow, it has the excellent effect of collecting the shavings and simultaneously reducing the air inside the game hall.
