Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an automatic tile splitting machine for cutting half-shaped tiles used at corners or ends into desired dimensions when tiling walls, floors, etc.

Conventional Technique Conventionally, this type of irregular tiles have been divided manually. That is, measure the split position with a scale, mark the split position by drawing a line on the tile surface with a pencil, etc., then mark the tile surface with a manual creasing cutter, and then add the marks. A convex table is placed under the tile, one side is held down with one's hands, and the other side is lightly tapped with a hammer or the like to break the tile to the desired size.

Problems that the invention aims to solve: However, the manual tiling described above is inefficient, so for example, when tiling a large area such as the exterior wall of a high-rise building, a large number of irregular tiles are required. This requires a dedicated worker to split the tiles, and since it is done by hand, there are many defective products due to mistakes in splitting.Furthermore, since the tiles are hard, fragments fly away during the splitting process, which is dangerous. There were other drawbacks.

Therefore, the present invention provides an automatic tile splitting machine which is capable of mass producing half-sized tiles of a preset desired size and which eliminates the above-mentioned drawbacks of the conventional tile splitting machine.

Means for Solving the Problems This invention is based on a machine 1 in which a large number of tile mounting pallets 2a each having a protrusion 11 for receiving the lower surface of the split portion of the tile T and a cushion material 2c are arranged at predetermined intervals. Tile conveying belts 2 arranged in parallel are mounted on an axis so as to rotate intermittently with a preset fixed stop time, and a strip pressurized by a pressing spring 3 or the like is attached to the upper part of the tile conveying belt 2. A creasing means A in which a creasing cutter 4 is positioned directly above the protrusion 11;
and a tile pressing means B, which is provided with a pair of pressing arms 6, 6, which are moved up and down by a cylinder 5, etc., and positioned on both sides of the protrusion 11 during the stop time of the tile conveying belt 2, is arranged in parallel in the front and back. The aim is to solve the above-mentioned problems by adopting the following technical means.

Function Since this invention has the above-mentioned configuration, when the tile T carried on the tile placement pallet 2a of the tile conveyance belt 2 passes the lower surface of the creasing means A, it is placed at the desired split position. When the tile T with the creases formed by the creasing cutter 4 reaches the lower surface of the tile pushing and splitting means B, the rotation of the tile conveying belt 2 is stopped and the tile T stands still.
After that, the cylinder 5 etc. are operated and the pressing arm 6,
6 and press both sides of the tile T line with arms 6, 6.
At the same time, the tile T is pushed down against the cushion material 2c, and the tile T is split into two from the warp line starting from the protrusion 11. Thereafter, when the pressing arms 6, 6 rise and return to their original positions, the tile conveying belt 2 starts rotating and moves on to the next dividing operation.

Embodiment An embodiment of the automatic tile splitting machine according to this invention will be described below with reference to the drawings.

In the drawing, 1 is a machine base, 2 is a tile conveying belt that rotates intermittently with a preset stop time on the machine base 1, and carries a large number of L-shaped pallets 2a for placing tiles at a predetermined interval. Endless chain 2
The endless chain 2b is installed in parallel with the drive shaft 7 on the machine base 1, and is connected to the sprocket gears 9 and 10 fixed to the driven shaft 8.
The intermittent rotation is performed by a control motor M, and the stop time, rotation speed, etc. can be freely controlled by a control panel C.

In addition, a sponge or other cushioning material 2c is fixed to the tile mounting pallet 2a, leaving a tile-engaging protrusion 2a' at the rear of the pallet 2a, and at any position on the pallet 2a, a sharp piece such as a hardened chip is fixed. The protrusion 11 is fixedly provided. Reference numeral 12 designates pallet guides provided on both lower surfaces of the sharp protrusion 11. A is a creasing means having a creasing cutter 4 which is pressurized by a pressing spring 3 or the like, and the creasing cutter 4 is a cutter roll similar to a so-called glass cutter and is pivoted at the tip of a support frame 4a so that it can rotate freely. The creasing means A is provided on the tile conveying belt 2 with its creasing cutter 4 positioned directly above the sharp protrusion 11. B is a tile pressing means equipped with a pair of pressing arms 6, 6 which are moved up and down by an air cylinder 5 etc. during the stop time of the tile conveying belt 2. The supporting rail 13 is fixed to the piston rod 14 of the air cylinder 5, and is movable up and down while keeping the horizontal position by means of a guide 15. The pressing arms 6, 6 are attached to the upper part of the conveyor belt 2.
are provided on both sides of the sharp protrusion 11. This tile pressing means B is arranged in parallel with the creasing means A at a constant distance from front to back. Note that the vertical movement of the support rail 13 by the air cylinder 5 is controlled by the control panel C so that it is performed within the stop time of the tile conveying belt 2.

In the figure, 16 is a top restraining guide of the conveying tile T;
Reference numeral 17 denotes a width adjustment guide on both sides of the conveyed tile T, 18 a work table, and 19 a discharge chute for half-odd tiles.The half-odd tiles are sorted by a partition plate 19a. Reference numeral 20 denotes a drive chain, which extends over a sprocket gear 22 fixed to the shaft 21 of the control motor M and a sprocket gear 23 fixed to the drive shaft 7 of the tile conveying belt 2.
24 is a compressor which is a driving source for the air cylinder 5.

In the above configuration, when the tiles T stacked on the work table 18 are manually placed one by one on a predetermined position on each pallet 2a of the tile conveying belt 2, the tiles T are placed on the engaging protrusion 2a. ' and is sequentially transferred to the right in the figure as the tile conveying belt 2 rotates intermittently, and when the tile T passes the lower surface of the creasing means A, the creasing cutter 4 cuts the creasing a at the split position. Can be attached. That is, since the creasing cutter 4 is pressurized downward by the pressing spring 3, etc., the creasing cutter 4 is strongly pressed against the upper surface of the tile T as the tile T moves and rotates, thereby carving the striations a on the tile surface. (see Figure 4). When the tile T with the creases a reaches the lower surface of the tile pushing and splitting means B, the rotation of the tile conveying belt 2 is stopped by a command from the control panel C, and the tile T stands still. After that, air cylinder 5
is activated by a command from the control panel C, and the pressing arms 6, 6 descend via the support rail 13, and the pressing arms 6, 6
Press down on both sides of the stripe a of tile T. Then,
Since both sides of the tile T curve downward starting from the sharp protrusions 11 supporting the tile T directly below the striation a, the tile T cracks into two from the striation a (see FIG. 5).
When this dividing operation is completed, the pressing arms 6, 6 are raised by the air cylinder 5 and returned to their original positions in response to a command from the control panel C, and at the same time, the tile conveying belt 2 starts rotating and moves on to the next dividing operation. be. The above-mentioned series of splitting operations are continuously repeated under instructions from the control panel C, and the split half-sized tiles are automatically taken out from the discharge chute 19. In addition, the allocation position of the tile T is, for example,
Any position from 5:5 to 1:9 can be freely selected by changing the position of placing the tile T on the pallet 2a and the position of the pressing arms 6, 6.

Effects of the invention As explained above, this invention automates the process from creasing with the creasing cutter to pressing with the pressing arm, making it possible to mass-produce odd tiles with preset desired dimensions. Compared to conventional tiles, work efficiency is improved, and costs are lower due to the ability to mass-produce uniform irregular tiles.
The work is safe and also contributes to so-called energy savings.
