 Next, the operation will be described.

 The principle operation is as follows.

Originally, the polishing member 20 having a smooth surface is used in a state in which the unevenness 26 for article friction is provided on the surface by the molding portion 40.
When the surface of the polishing member 20 is rubbed against the polishing target A,
The unevenness 26 is pressed against the polishing target A with resistance, and the polishing target A
Dirt and polishing debris on the surface are rubbed off by the irregularities 26.

When the unevenness 26 on the surface of the polishing member 20 is clogged, the surface is restored by the memory calling unit 50 provided facing the polishing member 20. When the polishing member 20 is heated by the memory recall unit 50, the polishing member
The surface of 20 becomes smooth, and dirt and the like attached to the unevenness 26 rises, so remove it. Thereafter, as described above, the surface of the polishing member 20 is newly provided with irregularities 26 in the forming section 40 and used.

The operation will be described in more detail with the object A to be polished being a ball-shaped pachinko ball.

The endless belt-shaped polishing member 20 wound between the frame members 21a and 21b disposed apart from each other has brake rollers 25a and 25
Stopped by being pressed by b.

The conveyor belt 30 is such that the rollers 31a and 31b are rotationally driven at an appropriate speed, and the portion of the polishing member 20 facing the polishing section 22 is the first portion.
In the figure, it moves continuously from left to right.

The object A to be polished, which is a ball-shaped object, is sandwiched between the conveyor belt 30 and the polishing member 20 from the left end, and the receiving plate 32 and the holding plate 32 are held.
When the polishing target A moves while being pressed between the polishing target 24 and the unevenness 26 on the surface of the polishing member 20 and is discharged from the right end, polishing is completed.

The irregularities 26 on the surface of the polishing member 20 cause clogging due to adhesion of dirt and polishing debris on the surface of the polishing target A during polishing. Therefore, when the degree of clogging exceeds the limit, the polishing member 20 is regenerated. Regeneration process is polishing section
It is done in the recovery section 23 opposite the 22.

When the braking is released by loosening the brake rollers 25a and 25b, the polishing member 20 becomes movable. Therefore, the mounting members 21a and 21b are rotated manually or by power to move. The polishing member 20 first passes through the memory recall unit 50, is heated and the unevenness 26 disappears,
The surface returns to its original shape and the surface becomes smooth, and dirt and the like attached to the irregularities 26 emerge.

Next, after the memory calling unit 50, the polishing member 20 passes through the cleaning unit 60, and the belt polishing roller 62 comes into contact with the surface of the polishing member 20 to peel off and remove attached dirt and the like.
66 sucks out the air in the cleaning chamber 61, and dirt and the like are accumulated in the filter 64. The filter 64 is appropriately replaced, and dust such as dirt is collected and discarded.

The polishing member 20 passes through the forming section 40 before entering the polishing section 22. In the forming section 40, the polishing member 20 passes between the notch roller 42 and the receiving roller 43, and the notch 42a on the surface of the notch roller 42 is formed.
Is pressed against the surface of the polishing member 20, and the unevenness 26 for article friction is formed on the surface of the polishing member 20.

The polishing member 20 moves until it is stretched over the polishing section 22 with the new unevenness 26, and finally the brake roller 25a,
The polishing member 20 is pressed and stopped at 25b.

When viewed as a process, in the polishing process, the irregularities 26 on the surface of the polishing member 20 are rubbed against the object A to be polished, and in the memory calling process, the surface of the polishing member 20 is heated by heating the polishing member 20 to which dirt or the like has adhered. The dirt and the like adhering to the unevenness 26 are smoothed out, and in the cleaning step, the dirt and the like adhering to the surface of the polishing member 20 are peeled off and removed.

In the above-described embodiment, the polishing member is an endless belt, and the regenerating process is performed by intermittently moving the polishing member according to the clogging of the unevenness. However, the polishing member slowly moves at a sufficiently slow speed compared to the transport belt. You may make it reproduce | regenerate continuously, making it.

As for the moving direction of the endless belt, the finished state is good if the regenerated polishing member is sent to the side where the polishing target is discharged.

Further, it goes without saying that the storage and recall unit and the forming unit may be moved without moving the polishing member.

[Advantages of the Invention] According to the polishing apparatus and the polishing method of the present invention, the polishing member is a shape memory resin, and the unevenness for polishing is formed to polish the object to be polished. Since the dirt and the like are removed in this manner, it is possible to eliminate clogging of the unevenness for polishing and easily regenerate, and it is possible to provide an extremely efficient polishing apparatus and polishing method.
