2. Description of the Related Art Conventionally, for example, the one disclosed in Japanese Utility Model Laid-Open No. 2-25288 is known as a ball polishing and lifting machine for pachinko balls of this type. In this conventional ball grinding lifter, a wear resistant elastic material, a soft elastic layer having a ball passage formed therein, and a sliding material are superposed in a guide rail facing the rising side of the lifting belt. A lifting path is formed between the sliding material and the lifting belt to lift the pachinko balls while holding them at an appropriate pressure.

[0003]

In a conventional pachinko ball ball polishing and lifting machine, since the pachinko ball lifting path is formed of three members, an elastic material, a flexible elastic layer, and a sliding material, There is a problem that the structure is complicated and the manufacturing cost is very high.

Further, since the pachinko balls guided from the ball guiding path in the lower part of the ball polishing lifter to the lifting path are lifted while being fitted in the ball paths of the flexible elastic layer, respectively. There is a problem that the manufacturing process is difficult or time-consuming because high accuracy is required for the positional relationship between the ball introduction path and the ball introduction path and the dimensions of the recess of the ball passage and the surface of the lifting belt.

It is an object of the present invention to obtain a ball polishing and lifting machine for pachinko balls, which has a simple structure and can be manufactured at low cost, and can exhibit a high polishing and lifting capacity.

[0006]

In order to achieve the above-mentioned object, in a pachinko ball ball lifter of the present invention, an endless pumping is provided between a drive roller and a driven roller arranged above and below the apparatus frame. While the belt is stretched, guide rails are arranged opposite to each other on the ascending side of the lifting belt, and a polishing cloth made of an elastic material is provided on the inner side surface of the guide rail to provide the lifting belt and the polishing cloth. In between, a hoisting path having an interval substantially equal to the ball diameter of the pachinko ball is formed, and innumerable bristles for forming a ball passage are arranged within the hoisting path.

[0007]

The pachinko balls in the hoisting path are nipped between the hoisting belt and the polishing cloth and hoisted. At this time, the cloth is pushed laterally by the pachinko balls to be lifted or collapsed in the lifting direction of the pachinko balls to naturally form a ball passage. Therefore, it is not necessary to form a ball passage in the hoisting passage, so that the structure is simple and can be easily manufactured.
