Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for cutting long ceramic tiles into desired dimensions, and in particular, to continuously cut two tile pieces of desired dimensions from one tile. The present invention relates to a device that allows the invention to be obtained.

Problems to be Solved by Conventional Technologies and Ideas For example, one of the methods for manufacturing corner tiles that are pasted on corners is a method in which two long and short tile pieces are butted together in an L-shape and then glued together. However, although the production volume of corner tiles is small, there are many types of corner tiles, and manufacturing each tile piece of a desired size would be extremely costly, so it is necessary to manufacture large quantities of long tiles of a certain size and then make the desired size. A commonly used method is to cut it to size before use. Conventionally, when cutting tiles in this way, the common method is to cut by placing one end of the tile along a ruler set to the desired size between the cutter and the cutter, and then pressing it against the cutter by feeding it on a belt conveyor or by hand. To obtain two tile pieces with different dimensions from a long tile, cut the required number of tile pieces of one size, then change the position of the ruler and cut another tile piece from the remaining tile pieces. The process involved cutting tile pieces of one size in two separate steps, resulting in low production efficiency.

Means for Solving the Problems The present invention has been proposed as a means to solve the above problems by installing a belt conveyor that conveys tiles in one direction, on both edges of the belt conveyor, in a direction perpendicular to the running direction of the belt conveyor. First and second rulers whose movement can be adjusted are disposed at intervals in the running direction of the belt conveyor, and first and second rulers corresponding to the first and second rulers are provided on the belt conveyor. The structure is equipped with a cutter.

Functions and Effects of the Invention Since the present invention has the above configuration, after setting the distance between the first ruler and the first cutter and the distance between the second ruler and the second cutter to desired dimensions,
When long tiles are fed onto a belt conveyor,
One end of the tile piece is fed along a first ruler and cut with a first cutter to obtain a first tile piece of the desired size, and then the other end of the tile piece that was left uncut is cut with a first cutter. The second tile piece is cut with the second cutter while being fed along the tile cutter to obtain a second tile piece of the desired size, and two types of tile pieces with different sizes can be manufactured continuously, increasing work efficiency. It has a significant improvement effect.

The position of the first cutter 45a is determined using the first ruler 60a.
Adjust the position of the second cutter 45b so that the distance from the parallel portion 64 of the second ruler 60b is the same as the dimension of the desired tile piece b, and adjust the position of the second cutter 45b so that the distance from the parallel portion 64 of the second ruler 60b to the desired tile piece b. Adjust it so that it is the same as the dimension of one side d, and then adjust both lifting bodies 30
By moving a and 30b up and down, the positions of both cutters 45a and 45b are adjusted to a height that matches the thickness of tile a, thereby completing the setting.

Then, when a long tile a is placed on the running belt conveyor 1 by touching the locking plate 7 and the inclined part 63 of the first ruler 60a, the tile a will move as it approaches the first cutter 45a. Therefore, the tape is conveyed along the locking plate 7 by the inclined part 63 of the first ruler 60a, gradually moving toward the left side in the running direction of the belt conveyor 1, and when it reaches the parallel part 64 of the first ruler 60a, By sandwiching the tile a between the belt conveyor 1 and the first pressing body 55a, movement in a direction perpendicular to the running direction of the belt conveyor 1 is restricted, and in this state, the first ruler 60
The first tile piece b having the desired dimensions is obtained by being cut by the first cutter 45a while being conveyed along the parallel portion 64 of the tile piece b. uncut tile piece c
When the uncut tile piece c is conveyed, the corner of the uncut tile piece c comes into contact with the inclined part 63 of the second ruler 60b, and gradually moves along the locking plate 7 as it approaches the second cutter 45b. The tile piece c is conveyed while being shifted to the right side in the running direction of the belt conveyor 1, and reaches the parallel part 64 of the second ruler 60b, and the uncut tile piece c is pressed by the second pressing body 55b. By cutting the second tile piece d with the second cutter 45b while being conveyed along the parallel part 64 of the second ruler 60b, the second tile piece d of the desired size is obtained, and the tiles a are sequentially cut. By conveying with the belt conveyor 1, two types of tile pieces b and d of desired dimensions are continuously obtained.

In the above embodiment, by forming the inclined portion 63 on the ruler 60, the tile a or the uncut tile piece c is conveyed in a state in contact with the ruler 60, and the parallel portion 64 of the ruler 60 is conveyed. When the tile a or the tile piece c is reached, the pressing body 55 presses the tile a or the tile piece c to restrict the movement in the direction perpendicular to the running direction of the belt conveyor 1. It is advantageous that the desired tile pieces b and d obtained have high dimensional accuracy because they are cut with one end edge always aligned with the ruler 60.
