Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an abrasive polishing device mainly used for polishing game media such as pachinko balls.

``Prior art'' Conventionally, in order to purify pachinko balls, which are used as gaming media to which dust, hand marks, etc. have adhered, there has been
Publication No., JP-A-58-92379, JP-A No. 1983-
As disclosed in Japanese Patent Publication No. 21268, a technique related to a polishing device for polishing pachinko balls is disclosed.

``Problems to be Solved by the Invention'' However, in such a conventional 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. Therefore, as disclosed in Japanese Patent Application Laid-Open No. 51-8043, dirty abrasives should be replaced with new ones regularly, or
As disclosed in Publication No. 92379 and Japanese Patent Publication No. 48-21268, the dirty abrasive material is removed and washed with detergent and detergent.
It was cleaned with cleaning liquid etc. However, replacing dirty abrasives with new abrasives wastes resources and money, and the technique of cleaning with cleaning liquid requires cleaning liquid, which requires drying after cleaning and disposal of the cleaning liquid. Requires processing equipment, etc.
There was a problem in that the cleaning equipment became large.

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

"Means for Solving the Problem" The gist of the present invention for achieving the above object is to agitate the game balls taken in from the game ball intake port and the abrasive material taken in from the abrasive material intake port. In a game ball polishing device that includes a polishing machine that polishes the game ball and a separator that separates the polished game ball and the abrasive material, the separated abrasive material is removed by cutting the surface layer of the abrasive material. A game ball polishing device that performs polishing using an abrasive material recycling machine that includes a machine, a sorter that separates the abrasive material whose surface layer has been scraped off and shavings, and a collector that collects the shavings. Exists in abrasive polishing equipment.

``Operation'' The abrasive material whose surface has been contaminated by pachinko balls in the abrasive machine is separated by a separator and guided to an abrasive material regenerating machine comprising a cutter, a sorter, and a collector. In this reproducing machine, the dirt on the abrasive is scraped off to obtain a fresh surface, and the material is led back to the polisher to polish away the dirt on the pachinko balls.

"Embodiment" An embodiment of the present invention will be described below based on 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 7 curved downward into a substantially arc shape, a motor 8 attached to the upper end of the tube 7, and a rotating shaft of the motor 8, which is connected to the shaft and inserted along the tube 7. It is generally composed of a spiral body 9. Near the lower end of the tube body 7 is a pachinko ball 1 fed from an out rail 10.
A pachinko ball intake port 11 for taking in the abrasive material 2 and an abrasive material intake port 12 for taking in the abrasive material 2 sent from the transportation path 5 are bored, and an outlet port 13 is bored near the upper end of the pipe body 7. has been done. Therefore, the polishing machine 3 stirs the pachinko balls 1 and the abrasive material 2 taken into the pipe body 7 through the intake ports 11 and 12 by the spiral body 9 driven by the motor 8, and conveys them from below to above. Can be done. Further, the separator 4 has a sieve 14 with an interval slightly smaller than the diameter of the pachinko balls 1, and when the mixture of the pachinko balls 1 and the abrasive material 2 passes over the sieve 14, the separator 4 Only the pachinko balls 1 can be sent to the gutter 15 by causing the balls 2 to fall downward.

Next, the regenerator 6 will be explained in detail using FIG. 2. In the figure, 16 indicates a sorter that separates the surface layer of the abrasive material 2 from shavings, and 18 indicates a collector that collects the shavings. The cutting machine 16 connects the transport paths 5, 5 and the sorting machine 1.
a container 19 having an opening at 7; and a blade rotating body 2 housed in the container 19 and rotated by a motor 20.
It consists of 1 and 21. The sorting machine 17 is composed of, for example, a container 22 and a Sirotskov fan 23 housed in the container 22 and rotated by a motor 20, which separates the abrasive material 2 by creating an air flow.
It is designed to absorb only the shavings. Further, as shown in FIG.
a container 26 having an outlet 25 and an outlet 25;
a motor 27 provided on the side wall of the motor 27;
The spring body 29 is fixed to the rotating shaft of the container 26 to stir the sol or liquid 28 (for example, starch water, water) in the container 26. Therefore,
The collector 18 introduces the air containing the shavings from the sorter 17 through the inlet 24 and causes it to collide with the liquid 28 in the collector 18, thereby absorbing the shavings into the liquid and producing fresh air. It is configured to be discharged from an outlet 25. Note that 30 is an abrasive material supply port for supplying new abrasive material 2.

The game ball polishing device according to this embodiment has the above-described configuration, and the abrasive material 2 whose surface has been soiled by the pachinko balls 1 in the polishing machine 3 is separated by the separator 4 and transported via the transport path 5. It is guided to the regenerator 6. In the regenerator 6, the abrasive material 2 obtains a fresh surface,
It is led to the polishing machine 3 again. Furthermore, since the regenerator 6 generates an air flow as shown by the arrow, the regenerator 6 also purifies the air in the game hall.

In addition, in this embodiment, the polishing machine 3 has a spiral body 9.
Although the above description assumes that a screw type is used, other types such as a screw type may also be used. In addition, some or all of the dirty abrasive material may be polished by passing it through a recycling machine.Furthermore, although the cutting machine 16 has been described as using the vane rotating body 21, file-like teeth are used on a disc or the like. It may be something that is provided. Furthermore, the collector 18
Although described above as using water or the like, it goes without saying that a filter type using fibers or a combination of a filter type and water or the like may be used.

"Effects of the Invention" The present invention is as described above, and includes a cutting machine that scrapes off the surface layer of dirty abrasive material, a sorting machine that separates the ground abrasive material from the scraped shavings, Since the abrasive is recycled using an abrasive recycling machine that includes a collector that collects shavings, dirty abrasive can be used many times without being discarded, and cleaning liquid, etc. Since dry polishing is not required, the device can be made smaller and simpler.
