The present invention relates to a method for polishing a surface of a plank and a device therefor, and in particular, by passing the plank through a predetermined direction between the grinding roller and the transfer roller to be polished by a rotating polishing roller, the surface portion of the rotating roller, the rotation direction of the feed roller The present invention relates to a method for polishing a surface of a plank and a device thereof so that one surface is polished in a surface contact state with a polishing roller rotating in the opposite direction.

In general, in the case of manufacturing mother-of-pearl, the mother-of-pearl of the shell, such as beating, abalone, etc. is polished to manufacture the mother-of-pearl in an appropriate form according to the size or shape of the shell, or the mother-of-pearl may not be shaped or partially broken during manufacturing. In this case, since the mother-of-pearl can not function as a mother-of-pearl, they are polished to a certain thickness, and a plurality of polished materials are properly recycled by manufacturing a plurality of polished materials formed by pressing and fixing the edges to overlap each other.

The plank or recycled mother-of-pearl made of such a process has a rough surface and uneven surface, and thus, the surface of the plank or recycled mother-of-pearl has been usually polished to produce a finished product of the plank or recycled mother-of-pearl.

Referring to the conventional surface polishing treatment method as shown in FIG. 8, the polishing roller 100 and the transfer roller 101 are installed in parallel with each other in the vertical direction, and the feed roller 101 is transferred by the rotational direction of the feed roller 101. Direction and the polishing roller (100) in the state of rotating in the same direction in the state in which the plank (R) is passed between the rollers (100, 101) to polish the surface portion thereof (hereinafter referred to as "forward rotation method") Has been applied.

However, in the forward rotation type as described above, the plank R passes between the polishing roller 100 rotating at a high speed and the transport roller 101 rotating at a relatively low speed. ) Is caused by the difference in the rotational force in the rotational direction due to the speed difference between the high-speed polishing roller 100 and the low-speed feed roller 101, resulting in a non-uniform polishing rate or feed rate of the plank (R) Plank (R) is not polished properly, the quality has been a factor of deterioration, and furthermore, the plank (R) has a disadvantage that is broken by the impact that is thrown out to the outside during the grinding process.

Therefore, in order to rule out the above disadvantages, the accurate rotation ratio between the polishing roller 100 and the transfer roller 101 and the accurate clearance adjustment between the rollers 100 and 101 were required, but there was a very difficult end to match them. Due to the need for fine thickness adjustment between the rollers 110 and 101, an extremely skillful technique is required for the surface polishing of the plank R.

In addition, even if the rotational ratio between the abrasive roller 100 and the transfer roller 101 is applied accurately, the plank (R) while being transferred in the forward rotation direction of the abrasive roller 100 that rotates at a relatively high speed compared to the transfer roller 100 Because the surface part of is polished, the surface polishing efficiency is inferior due to the nonuniformity of feed and polishing speed, and thus, it is not possible to exclude the disadvantage that the work efficiency is reduced because several times of repeated work are required.

The present invention in order to solve the problems of the prior art as described above in the opposite direction to the rotation direction of the transfer roller for transporting the plank in a predetermined direction and the rotational direction of the polishing roller for polishing one surface portion of the plank In the case of applying the rotating method (hereinafter referred to as "reverse rotation method") was developed based on the fact that the feed rate and polishing speed of the plank can be made uniform, the present invention has the following object.

That is, the first object of the present invention is a surface polishing method of the surface of the plank applying a reverse rotation method to transfer the plank through the grinding roller rotating in the opposite direction to the rotating direction of the transfer roller to be transferred in a predetermined direction to polish one surface portion and In providing a device.

The second object of the present invention is to apply the reverse rotation method compared to the conventional forward rotation method, the ease of controlling the polishing and feed speed of the polishing roller and the transfer roller and the thickness control according to the plank is required less and also if necessary The present invention provides an easy surface polishing method and apparatus therefor.

A third object of the present invention is to provide a method and apparatus for polishing a surface of a plank that can be applied without the need for an experienced technique according to the surface grinding of the plank, thereby improving productivity and improving its quality.

The present invention applies a reverse rotation method for rotating the polishing roller in a direction opposite to the rotation direction of the transport roller for transporting the plank in a predetermined direction in order to achieve the above object, the rotation ratio of the feed roller and the polishing roller By applying the independent driving method that can be precisely adjusted.
