Abstract

PROBLEM TO BE SOLVED: To arrange more pachinko stands in a prescribed interval than in a conventional manner and also to easily maintain and manage a grinding means by arranging the grinding means in the lower part of a game part in a base stand and also permitting the means to be freely drawing-out possible at the front surface side of the game part. SOLUTION: The grinding means D is arranged in the lower part of the game part 11 in the base stand 10 so as to be freely drawing-out possible at the front surface side of the game part 11. Pachinko balls B supplied from a storing tank 16 are ground by the grinding means D and adhered trash, dust or finger marks, etc., is removed. A lower tank 17 is arranged in the lower part of the game part 11 in the base stand 10. The PACHINKO balls B ground by the grinding means D are temporarily stored in the lower tank 17. Then, the balls B stored in the lower tank 17 are elevated to an upper tank 12 by an elevating means 18 which is driven under a fixed condition so as to elevate it to the upper tank 12. The fixed condition means a case when the PACHINKO balls B to be supplied becomes short in the upper tank 12.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing machine for pachinko balls.

[0002]

2. Description of the Related Art In a conventional polishing apparatus of this kind, a polishing means is disposed between adjacent pachinko machines, and while polishing the pachinko balls used in this pachinko machine to an upper upper tank, polishing is performed to remove dirt. Had been dropped.

[0003]

However, since the polishing means requires a required space, a conventional pachinko ball polishing apparatus has to secure a required space between adjacent pachinko machines. Had the disadvantage of having to do so.

An object of the present invention is to eliminate such inconvenience.

[0005]

In order to achieve the above object, a polishing machine for pachinko balls according to the present invention comprises:
A pachinko machine with a playing unit on the base and a polishing means,
In a pachinko ball polishing apparatus for polishing a pachinko ball used on the pachinko machine by the polishing means, the polishing means is disposed below the play portion on the base and the polishing means is disposed on the front side of the play portion. The space which has not been conventionally used in the pachinko machine can be effectively used for the polishing means, and the maintenance and management thereof can be facilitated.

The polishing means has a pachinko ball feeder, and the pachinko ball feeder is provided with a drive shaft and a driven shaft provided on a substrate, and a feed belt wound between the drive shaft and the driven shaft. And a polishing rail installed on the substrate and disposed substantially in parallel with the belt, if these drive shafts and driven shafts are in a cantilever state with respect to the substrate,
Since the feed belt can be taken out, the maintenance of the polishing apparatus can be easily performed.

In addition, if the drive shaft and the driven shaft are arranged so as to be at an up and down position, and the feed belt is made swingable about a drive shaft or a driven shaft located below together with its frame as a swing center. In addition, since the swing of the feed belt can be fixed by gravity and the swing shaft can be used also as a drive shaft or a driven shaft, the configuration of the device can be simplified.

The pachinko ball feeding section includes a tension device for adjusting the tension of the feed belt, and if the tension device also functions as a lock device for the feed belt, the feed belt is separately provided from the tension device. Since there is no need to provide a lock device, the configuration of the device can be simplified.

The pachinko ball feeding section is provided with a ball taking-in member for supplying pachinko balls to the feed belt via the ball taking-in member, and the ball taking-in member can be pulled out to the surface side of the play section. If this is the case, the maintenance of the ball intake member can be facilitated.

If the drive shaft is arranged below the driven shaft, the drive means such as a motor can be arranged below, so that the stability of the device itself is improved.

If the feed belt is arranged obliquely, it is possible to increase the distance of the feed belt in a predetermined space and to pinch pachinko balls by the gravity of the belt. Further, when the feed belt is set, the feed belt can be leaned by gravity, so that the maintenance is easy.

If the polishing rail is installed so as to be able to advance and retreat with respect to the feed belt, the pachinko balls can pass smoothly.

If a ball guide is fixed immediately before the polishing rail on the substrate, and a pachinko ball is supplied to the polishing rail via the ball guide, for example,
Even if the polishing rail is movable, pachinko balls can be properly supplied on the rail.

If a caster is provided on the polishing means, the polishing means can be smoothly pulled out from the pachinko machine.
