Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention collects game balls discharged from a large number of game machines installed in a pachinko game arcade and pumps them to a supply route connected to a prize ball tank provided at the top of the game machine. While it is an up-and-down polishing device that polishes a game ball.

[0002]

2. Description of the Related Art Conventionally, there is JP-A-57-29385 as an elevating and lowering polishing apparatus for game balls. According to this publication, the game ball is configured to face the rising surface of the lifting belt and press the flexible elastic layer forming the game ball passage having a groove-shaped cross section toward the belt side through the elastic spring. ing. And
The game balls are arranged in the concave groove and are lifted while rotating and sliding, and are polished when rotating and sliding.

[0003]

The structure of the polishing apparatus having the above-described structure is complicated, there are many assembly parts, and many steps are required for assembly. Further, since the elastic spring is used, it is necessary to replace the elastic spring at appropriate intervals. Therefore, an up-and-down polishing apparatus having a simple structure is desired.

[0004]

In order to solve the above-mentioned problems, the up-and-down polishing apparatus for a game ball according to claim 1 is one in which the game ball sliding surface is made of a soft material. In addition, the entrance of the game ball formed in the lower part of the lower roller is provided with a guide member that is rotatable along the lower roller around the entrance side and forms a sliding surface with the game ball and a flexible material. The elastic body is configured to press the lower roller side.

[0005]

[Function] The game ball is sandwiched between the lifting belt and the soft material layer,
It is rotated and slid to be pumped. Then, the game ball is polished by the soft material layer when slidingly rotating. Further, since the game ball is thrown in through the guide member which receives the pressing force by the elastic body, it is smoothly rotated and slid between the lift belt and the guide member, and discharged to the rising surface of the lift belt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An elevating and lowering polishing apparatus 1 for a game ball according to the present invention will be described with reference to the drawings. FIG. 1 is an overall perspective view with an opening / closing cover 2a in an open state, FIG. 2 A ~
A sectional view is shown. Reference numeral 5 is an upper roller, 6 is a lower roller, a lifting belt 10 is stretched between the rollers 5 and 6, guide rollers 7 are arranged at appropriate intervals, and the rollers are rotated via an electric motor 14. To do. 8 is a roller for adjusting the belt tension, which is a bolt 9a attached to the support frame 11,
Adjust via nut 9b. The rollers 5, 6, the lifting belt 10 and the like are covered with an opening / closing cover 2a and a fixed cover 2b, and a trumpet-shaped game ball discharge port 3 is formed in the upper part and a game ball entrance 4 is formed in the lower part. There is. The opening / closing cover 2a has a U-shaped cross section, is attached to the fixed cover 2a via the hinge 2c so as to be openable / closable with a length corresponding to the rising surface of the lifting belt 10, and is closed by the hook 2d. To do. A removable frame 12 having a U-shaped cross section is fixed inside the opening / closing cover 2a by a double-sided tape 13 or the like, and the frame 12 is formed of a polyester resin or the like and has elasticity and flexibility. The material 15 is attached. A guide member 20 is attached to the lower portion of the lower roller 6 so as to be rotatable around a shaft 21 provided on the support frame 11 along the outer peripheral shape of the lower roller 6. The guide member 20 is a thin plate-shaped frame 20a.
The flexible material 15 is attached to the inner peripheral surface of the. or,
A stop plate 23 is horizontally formed on a support body 22 provided on the outer periphery of the guide member 20, and the support rod 2 into which the elastic body 25 is inserted is inserted.
4a is a gap between the support rod 24b provided upright on the support frame 11 and the gap 2
6 are provided so as to face each other in a state of having the guide member 6, and the guide member 2
0 is constantly pressed by the elastic body 25 toward the lower roller 6 side. The elastic body 25 is selected to have strength enough to sandwich one game ball between the lower roller 6 and the guide member via a bolt 27 inserted through the stop plate 23 and a pair of nuts 28. The lower limit of movement of 20 is configured to be adjustable to prevent the game balls Y from being overlapped and sent.

Explaining the operation of the elevating type polishing apparatus having the above construction, a large number of game balls Y flowing down from the inlet 4 flow between the guide member 20 and the lower roller 6. Then, the game ball Y that has flowed in presses the guide member 20 downward, but the elastic material 25 is elastically sandwiched between the lower roller 6 and the flexible roller 15 with low frictional resistance. It rises while sliding and rotating. Similarly, the game ball Y is also conveyed on the rising surface of the lifting belt 10 while slidingly rotating with the soft material 15, and is discharged from the discharge port 3 in a polished state. In addition, a large number of game balls Y inserted from the inlet 4 are sandwiched by the elastic body 25 that presses the guide member 20 one by one, and the guide member 20 further includes the nut 2
Since the support 22 adjusted to the position corresponding to 8 prevents the game balls Y from falling, the game balls Y are discharged to the rising surface of the lifting belt 10 while avoiding the overlapping state. In addition, the game sphere with the above-mentioned configuration can process 1.5 million pieces / Hr.
When the soft material 15 is soiled, the open / close cover 2a is opened, the frame 12 is removed, and a new frame 12 is attached with double-sided tape or the like. Thus, the soiled soft material can be easily replaced.

EFFECT OF THE INVENTION The elevating and lowering polishing apparatus for game balls of the present invention has a simple structure in which a flexible member is provided facing the rising surface of the lifting belt, and can be manufactured at a lower cost than the conventional one and the processing amount can be increased. There are many effects.
