DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semi-plastic body cutting apparatus used for cutting a semi-plastic body of a lightweight cellular concrete (ALC) panel in a process of manufacturing the panel.

[0002]

2. Description of the Related Art Conventionally, an ALC having a width of about 600 mm is generally used.
In the case of manufacturing a panel, although not shown, the depth is about 650 mm, the width is about 1500 mm, and the length is about 6000 mm.
The raw material slurry is poured into a casting mold having a rectangular shape and foamed, and after a desired time has passed, the slurry is cured to a semi-plastic state. Then, the four side plates of the mold are removed to expose the semi-plastic body. In this state, the semi-plastic body is cut by an upper surface cutting machine so as to have a height of about 605 mm.

[0003] Next, in a state where the long side of the semi-plastic body is gripped and lifted, the vertical piano wire is moved in the direction perpendicular to the rectangular parallelepiped semi-plastic body and cut into a desired length.
Then, the cutting device 1 shown in FIG.
Then, the sample is transferred onto the cutting bed 11.

[0004] The main part of the cutting device 10 is composed of a cutting bed 11 and a cutting cart 13, and the horizontal cutting bed 1 is provided.
Reference numeral 1 denotes a machine whose length is almost the same as the length of the formwork, and a plurality of machine bases 11a which can be moved up and down by cylinders 11b individually arranged on the bottom surface.

A cutting truck 13 is disposed from above the cutting bed 11 to the side (see FIG. 2), and the cutting truck 13 has vertical piano wires 1 at intervals corresponding to the panel thickness.
A square frame 12 with 2a is attached. And, along a pair of guide rails 13a laid horizontally on both sides of the cutting bed 11, it can reciprocate horizontally in the entire length thereof.

[0006] The semi-plastic body 1 placed on the cutting bed 11 of the cutting device 10 is provided with a frame 12 attached to the cutting cart 13 as the cutting cart 13 moves on the guide rail 13a. It is cut vertically to the desired width by the piano wire 12a. Thereafter, the cut semi-plastic body 1 is housed in a curing mold (not shown) and then charged into an autoclave, and steam-cured at a high temperature and a high pressure for a desired time to produce an ALC panel. Then, the assembly of the ALC panels is taken out of the mold, and the small face and the surface are cut according to the product specifications of each panel to obtain an ALC panel product.

When the semi-plastic body 1 is cut into a desired width at one time, the end 1a in the width direction cannot be commercialized due to problems in dimensional accuracy and surface shape.
When the semi-plastic body 1 is cut, the semi-plastic body 1 is peeled off from the inner adjacent portion 1b by the peeling mechanism 14 as shown in FIG. However, for example, when manufacturing an ALC panel containing a water repellent, it is necessary to load the end portion 1a into the autoclave at the same time as the central portion, and carry out steam curing for a desired time.

In this case, if the end portion 1a is not fixed to the inner adjacent portion 1b when the semi-plastic body 1 is cut, the semi-plastic body 1 peels off during cutting and falls. Therefore, a jig 1 in which a worker bent an iron wire as shown in FIG.
5 are inserted from above across the end 1a and the long side edge of the inner adjacent portion 1b.

However, this operation requires workers on both sides of the cutting trolley 13 and is troublesome, and furthermore, is a work in a narrow place near the moving cutting trolley 13 and has a safety problem. . After the steam curing in the autoclave, the jig 15 is no longer necessary together with the end 1a.
5 is removed and collected and used repeatedly, but there is also a problem that the collection work is troublesome.
