Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is used in pachinko games, where game balls ejected from a pachinko machine are This relates to the Tamama lifting device that polishes and lifts the polishing to the supply tank on the upper part of the island.

[Conventional technology]

Balls are absolutely essential in the automatic circulation mechanism of game balls in pachinko games. Many proposals for polishing and feeding devices have been made. Among them, the upright lifting machine rotates with power. A guide rail (support wall) is installed in the longitudinal direction opposite the rising side surface of the lifting belt. However, in order to maintain a uniform clamping force to clamp and lift the balls between the guide rail and the lifting belt, There were many problems.

0003 For example, on the surface of a plate-shaped urethane rubber, semicircular ball passages (in this example, there are five rows) are prepared. ), an elastic spring mounting part is formed on the back surface, and an elastic spring is mounted on the elastic spring mounting part. The conventional method was to attach the guide rail manually and lay it on the bottom of the guide rail support frame. Not only is the process complicated, but it takes a lot of adjustment work, and it is not easy to find defective parts, making replacement work difficult. Moreover, the protrusion of the tension roller provided on the lifting belt side as shown in Fig. 6 is difficult. There were also problems such as insufficient clamping in other places due to the meeting point of the ball and the ball (see Figure 6). Sara Due to long-term use during high-speed lifting, metal fatigue occurs and uneven wear occurs, resulting in The clamping force between the polishing cloth and the polishing cloth decreases, and it is no longer possible to maintain a uniform clamping force that is ideal for bead lifting and polishing. It became difficult. Also, due to the above reasons, the polishing cloth that comes into direct contact with the ball path may be partially damaged. This created a vicious cycle in which the replacement period was brought forward.

[Problem that the idea aims to solve]

In order to solve the above-mentioned problem, the ball diameter is large in the longitudinal direction inside the guide rail support frame. A partition wall is provided in each row, and a highly elastic material is laid in each row to form an independent partition ball passage. It is something that can be achieved.

[Effect]

The operation of the present invention will be explained. The balls ejected from each pachinko machine as out balls are Introducing balls that are collected into an out ball tank (not shown) and communicated with the out ball tank It flows into the lower part of the doffing machine A from the port C. The inflowing balls are polished by the rotation of the lifting belt 2. It is polished and sent to the upper ball outlet D.

[0007] Figure 2 shows the state of the lifting path K in which balls are sandwiched between the lifting belt 2 and the guide rail 4. . The pachinko balls introduced into the transport path K divided by the partition wall 6 are laid out in rows with elasticity. Since the balls are held in a substantially sunken state by the polishing cloth 10 between the high members, the adjacent balls There is no impact on the horizontal direction due to the grounding point and ball passage, and the lifting belt 2 The ball rotates on its own axis on the polishing cloth 10 by the rotational force of , and is lifted while being polished.
