Abstract

PURPOSE:To prevent polished tiles from moving, flying up, and being damaged during polishing operation even when the tiles have somewhat demensional errors and to easily place, fix, and remove them by holding the polished tiles by front and rear holding parts of holding bodies, and providing clearances between the holding bodies by springs provided on the front edges of the holding bodies. CONSTITUTION:Plural holding bodies 3, 3a are slidably loaded inside a frame body 2, a loading faces 4 are formed on the upper faces of the holding bodies, springs 6, 6a are provided on the rear edge parts to be projected, and bolts 16, 16a for pressing the holding bodies 3, 3a are loaded in the rear of the frame body 2. Further, the bolts 16, 16a are retracted to provide clearance between the holding bodies 3, 3a by resilient force of the springs 6, 6a to ensure loading spaces larger than polished tiles M, M'. Then the lined-up polished tiles M, M' are loaded on the loading places at one time, the bolts 16, 16a are advanced to hold and fix the polished tiles M, M' by front and rear holding parts 5 to be polished by a polishing machine. Finally, the bolts 16, 16a are retracted to release holding and fixing of the tiles, and the polished tiles M, M' are then removed at one time.

Description

[Detailed Description of the Invention] [Object of the Invention] The present invention provides a method for removing polished tiles that move or fly away when polished tiles are polished on a belt conveyor or on a table. This invention relates to a polishing tile fixing device which prevents damage to the polishing tile and also allows the polished tile to be easily placed, fixed and removed from the fixing device.

Traditionally, polished tiles were polished by placing them individually on an endless conveyor belt or table, and placing a rotating and/or swinging polishing stone above against the polished tiles. It has the disadvantage that it moves or flies off due to the rotational force and/or rocking force of the polishing stone, making it impossible to achieve satisfactory polishing.

Therefore, frames were fixed on all sides of the surface of the plate and the polished tiles were placed in alignment within the surface frame of the plate, but the polished tiles could shrink, warp, or deform during firing. Since there are some dimensional errors in each piece, the polished tiles inside the frame do not come into perfect contact with the adjacent polished tiles, so they may move or fly away (especially in the case of the swinging type). ), the polished tiles cannot be polished satisfactorily, and the polished tiles come into contact with each other and collide, resulting in chipping and damage of the polished tiles.

Further, as mentioned above, since the rolled tiles are arranged and placed adjacently within the frame with as little gap as possible, there is not enough room, and the arrangement 12 has the disadvantage of requiring time and effort.

The present invention is designed to reduce shrinkage, distortion, and
When polishing a polished tile that has some dimensional errors due to deformation, it is necessary to prevent the polished tile from moving or flying off, and to prevent damage to the polished tile because the polished tiles are not in contact with each other. To provide a fixture for fixing polished tiles that can be easily placed, fixed, and removed.

[Structure of the invention]

Section: The present invention is based on the above-mentioned conventional technology, in view of the difficulty of fixing polished tiles due to dimensional errors and the problem of damage. To solve the above problems, the tiles are fixed so that they are not damaged, and the springs on the front edges of the clamping bodies allow the clamping bodies to return to each other with a gap so that polished tiles can be easily placed and removed. It is something to do.

Function The present invention moves the bolt backward, creates a gap between the clamping bodies using the elastic force of the spring, secures a place larger than the polished tiles, transfers the aligned polished tiles at once, and then removes the bolt. The polishing tile is held and fixed by the front and rear holding parts and polished by the polishing machine.Finally, the lever bolt is moved back to release the holding and fixation, and the polished tile is transferred all at once.

Hereinafter, one embodiment of the present invention will be described based on the drawings. 1 is a fixing device for holding and accommodating a large number of polished tiles M, M'... A clamping body 3.3a is slidably mounted inside the frame body 2,
A mounting surface 4 is formed on the upper surface of the clamping body 3.3a, which is lower than the frame body 2, a clamping part 5 is provided projecting above the rear edge, and a spring 6.6a is mounted on the front edge. It is installed protrudingly.

Although not shown, rubber bodies or the like are attached to the front and rear surfaces of the holding portion 50.

The frame body 2 is composed of left and right frames 7.7a, a front frame 8 and a rear frame 9, and the left and right frames 7.78 are horizontally arranged inside both ends. ! jI
