SUMMARY OF THE INVENTION In a conventional pachinko ball ball polishing and lifting machine, in order to reduce frictional resistance between the apparatus frame and the lifting belt, a large number of balls are provided on the rear surface side of the lifting section of the lifting belt. Since the guide rollers are provided in the up-down direction and the lifting belt is moved while being in contact with a large number of guide rollers, the lifting belt is lifted while being sandwiched by the lifting path between the lifting belt and the polishing member. When a pachinko ball is passing through the guide roller portion, the unevenness of the lifting belt caused by the pachinko ball and the guide roller collide with each other, which causes noise.

Further, as described in Japanese Patent Application Laid-Open No. 7-155456, unevenness of a constant pitch is formed on the back side of the lifting belt, and unevenness of the same pitch is formed on the surfaces of the driving roller and the driven roller, and then the lifting belt is fed. In a ball patrol machine for pachinko balls, in which the unevenness of the belt and the unevenness of the driving roller and the driven roller are fitted to each other so that the lifting belt moves without slipping on both rollers, a guide roller There is a problem in that the unevenness of the lifting belt and the unevenness of the lifting belt always collide with each other to generate more intense noise, and a solution thereof has been strongly desired.

The present invention has been made in view of the above problems, and an object thereof is to effectively eliminate the generation of noise due to the collision of many guide rails and the unevenness of the lifting belt. An object of the present invention is to provide a pachinko ball polishing machine.

[0006]

In order to achieve the above object, the present invention provides an endless feeding belt between a driving roller and a driven roller arranged above and below a device frame, and A large number of guide rollers are provided in the vertical direction on the back surface side of the lifting portion of the belt, and pachinko balls flowing into the ball guide path at the bottom of the device frame are provided with a polishing member facing the lifting belt with a substantially spherical diameter interval. In a pachinko ball ball hoisting and hoisting machine which is lifted upward while being sandwiched at an appropriate pressure in a hoisting path between them, an endless auxiliary belt is hung between the plurality of guide rollers and the auxiliary belt is hoisted. It is designed to be superposed on the back side of the feeding section of the feeding belt.

Therefore, the unevenness of the lifting belt caused by the pachinko balls is absorbed by the auxiliary belt and does not collide with the guide roller, so that the noise can be completely eliminated.

Further, in the case where unevenness having a constant pitch is formed on the back side of the lifting belt, the uneven surface is protected by the auxiliary belt in addition to the elimination of noise, so that the uneven surface is prevented from being damaged. be able to.

As shown in FIG. 4, the lifting belt 14 has irregularities 16 having a constant pitch formed on the back side thereof, and is fitted into irregularities 12a and 13a having the same pitch formed on the surfaces of the driving roller 12 and the driven roller 13. The lifting belt 14 is tightly moved so as to reliably move with the driving roller 12 and the driven roller 13 without slipping. Further, a large number of guide rollers 17 are vertically provided on the rear surface side of the lifting portion (the side that moves upward) 14a of the lifting belt 14. The guide roller 17 normally rotates in contact with the lifting belt 14, and plays a role of reducing contact resistance and smoothing the movement of the lifting belt 14.

A gutter-shaped guide rail 18 is attached to the apparatus frame 11 so as to face the lifting portion 14a of the lifting belt 14,
A polishing member 19 such as a cloth or a blanket is provided on the inner surface of the guide rail 18. Then, the pachinko balls are hoisted upward while sandwiching the pachinko ball between the polishing member 19 and the hoisting portion 14a of the hoisting belt 14 with an appropriate pressure. Since the guide rail 18 needs to be replaced when the polishing member 19 becomes dirty, one side is hinged to the device frame 11 so as to be openable and closable, and the free end side is closed by the opening / closing hook 20. There is. Therefore, the guide rail 18 can be opened by approximately 180 degrees by removing the opening / closing hook 20, and the polishing member 19 can be easily replaced.

On the other hand, at the lower part of the apparatus frame 11, there is provided a curved sphere passage 21 which is curved in an arc shape so as to surround substantially the outer circumference of the drive roller 12, and the sphere guide passage 22 is provided in the curved sphere passage 21. It is connected. The sphere guide path 22 has a plurality of sphere paths 23 slightly larger than the ball diameter of the pachinko sphere formed by the thin strip 22a.
Bending ball passage 21 while aligning the pachinko balls flowing down
It is supposed to lead to. Then, by driving the driving roller 15, the pachinko ball is lifted to lift the belt 14 and the polishing member 1.
It is configured such that it is sent to a feeding path between the upper and the lower part 9 and polishing-lifted, and is sent from an upper ball outlet 24 to a replenishing system path (not shown). In addition, 25 is a tension roller of the lifting belt 14, and 26 is a ball stopping device that closes the ball passage 23 of the ball guiding path 22 and prevents the pachinko ball from being fed into the curved ball passage 21 by a switch operation when the operation is stopped. is there.

Therefore, in the present invention, the endless auxiliary belt 27 is stretched between the large number of guide rollers 17, and the auxiliary belt 27 is lifted by the lifting portion 14 of the lifting belt 14.
a The back side is polymerized. The auxiliary belt 27 preferably has a cushioning property such as rubber or urethane resin, and its lateral width is selected to be substantially equal to that of the lifting belt 14.

Further, as shown in FIGS. 3 and 4, the plurality of guide rollers 17 are provided with left and right side walls 28, 28 and the receiving plate 2.
Vertical rail frame 30 formed in a U-shaped cross section by 9 and
