[Industrial Application Field] The present invention is a semi-plastic material that can accurately and efficiently cut semi-plastic materials such as steam-cured lightweight aerated concrete slabs (hereinafter referred to as ALC slabs) into various dimensions in a semi-plastic state. It relates to a body cutting device.

0002

[Prior Art] Conventionally, ALC plates are generally made by placing reinforcing materials such as reinforcing bars in a formwork in a predetermined manner, and then injecting raw material slurry and foaming, which then becomes semi-plastic. At this point, the formwork is removed, the top and side surfaces are cut to a predetermined size, and then the product is manufactured by cutting to a predetermined thickness using steel wire, curing in an autoclave, and curing the product. In recent years, the demand for ALC plates for use in small-sized buildings or buildings with complex shapes has increased, and along with this, requirements for the length and width dimensions of ALC plates have also diversified.

[0003]Therefore, methods for manufacturing ALC plates of different lengths include, for example, providing partition plates at predetermined positions in the formwork and injecting raw material slurry, or manufacturing products of rated dimensions. A method of cutting the semi-plastic body as desired, a method of having a worker cut the semi-plastic body one by one into a predetermined size from the upper surface with a serrated cutting blade while it is stored in a formwork in a semi-plastic state, or a method of actually cutting the semi-plastic body one by one with a serrated cutting blade. Kosho 63-3904
There is a method of using a device such as that disclosed in Japanese Patent No. 7.

0004

[Problem to be Solved by the Invention] However, with the method of providing partition plates in the formwork, it is almost impossible to partition one lot into various lengths because there is a process of cutting to a predetermined thickness. There is a problem that. or,
The method of cutting the product into desired dimensions not only requires time and effort, but also has the problem of lowering the yield of the product. Furthermore, the method of cutting by a worker in a semi-plastic state poses safety problems as the worker must work in an unstable position as they cut each piece to a predetermined size from above using a serrated cutting blade. However, there are quality issues such as partial product defects and dimensional accuracy. Note that when cutting a product using a device such as that disclosed in Japanese Utility Model Publication No. 63-39047, if the cutting dimension is larger than the pulley diameter of the bandsaw, it cannot be cut at once and must be cut several times. There is a problem in that it is necessary to cut the

Note that 28 is a rotating cylinder, which may be attached to the upper part of the holder 21 as necessary so that the holder 21 to which the cutting blade 20 is attached can be rotated 90 degrees, and does not necessarily need to be always provided.

Since the device of the present invention is constructed as described above, first, the rotary cylinder 28 is operated to rotate the cutting blade 20.
is adjusted so that the flat part of the rail 15 is parallel to the rail 15 (thereby, it becomes parallel to the width direction of the semi-plastic body 2), and the lifting cylinder 26 is operated in the contraction direction to raise the presser plate 25. The frame portion 6 on which the cart 12 in this state is placed is kept waiting outside the pedestal 3 (on the left side in FIGS. 1 and 2).

Next, the formwork 1 containing the semi-plastic material 2 cut into a predetermined thickness is placed at a predetermined position on the pedestal 3. At this time, the longitudinal direction of the formwork 1 is the rail 4

During this cutting operation, by lightly pressing the presser plate 25 against the two surfaces of the semi-plastic body, it is possible to prevent cracks and defects from occurring on the cut surface.

Note that the semi-plastic body 2 can be cut in the right angle direction by operating the rotating cylinder 28 to rotate the holder 21 in the right angle direction and then moving the presser plate 25 and the cutting blade 20 up and down. . Further, by appropriately selecting the width of the cutting blade 20 and repeating cutting by moving it many times in the length direction and width direction of the semi-plastic body 2, it is also possible to cut it into a rectangular frame shape. Note that when cutting the semi-plastic body 2 only in one direction, the rotation mechanism of the holder 21 is not necessary, and when cutting the semi-plastic body 2 in two orthogonal directions, the rotation mechanism of the holder 21 is not required.
Instead of rotating the cutting mechanism, another cutting mechanism may be provided on the carriage 12 to cut in the right angle direction.
