Description

[Detailed explanation of the invention] (Industrial application field) This invention was developed using an ALC panel that can be cut with high precision on the same mounting table in order to obtain lightweight aerated concrete panels (hereinafter referred to as ALC panels) with sequentially different widths.
This invention relates to a panel cutting device.

(Prior Art) In recent years, the use of ALC panels for small-scale construction has been increasing, and as a result, the number of orders for panels that vary in length and width has increased.

To produce lightweight aerated concrete, reinforcing steel bars are placed in a formwork, raw material slurry is injected and foamed, then the formwork is removed in a semi-plastic state and cut to the desired thickness using piano wire, etc. In addition, the piano wire is cut into a certain length by crossing the piano wire so that the length direction is perpendicular to the thickness direction, and the product is cured in an autoclave. Therefore, a plate material having constant dimensions in width and length can be obtained.

However, in order to produce panels with varying lengths and widths, take out this ALC panel and place multiple panels on a mounting table with the side facing up.
After manually extruding one or two panels by the required length in the longitudinal direction, aligning the cutting position on the opposite side of the mounting table in a plane perpendicular to the longitudinal direction of the panel,
Cut with a saw, and for width cutting, rotate the panel cut to length using the method described above 90 degrees,
Place the panel on the mounting table again, manually extrude one or two panels by the required width in the width direction, align the cutting position parallel to the longitudinal direction of the panel, and then cut with a saw to length and width. was cut in two steps.

However, with the conventional cutting configuration described above, the cutting operation requires many man-hours and a long time, and there is also a risk that the dimensional accuracy may deteriorate, which poses a problem in the finishing process of the panel.

Therefore, among the above problems, regarding the device that changes the length of the ALC panel and cuts it, the Utility Application
This problem can be solved by using a device like No. 164394. In other words, multiple ALC panels arranged in parallel in the thickness direction with their sides facing up are placed on a mounting table, and one edge side of the ALC panels on this mounting table is moved in the thickness direction of the panel as well. An extrusion device has an extrusion cylinder that can control the extrusion size, and a cutting device that runs perpendicular to the longitudinal direction of the ALC panel is installed on the other edge side. After extruding the panel by the length and aligning the cutting positions with a plane perpendicular to the longitudinal direction of the panel on the opposite side of the mounting table, the panel is cut.

(Problems to be Solved by the Invention) However, the device having the above configuration has a problem in that the same operation as before is required to cut in the width direction.

(Means for solving the problem) In order to solve the above-mentioned problem, this invention is a plate that can be vertically raised and lowered while supporting the bottom surface of each ALC panel arranged in parallel in the thickness direction with the side facing up. The mounting table is equipped with a mechanism to raise the panel to a desired height, and the width of the protruding panel can be cut with a horizontal bandsaw.

(Function) In this way, the width of each panel can be cut to a desired size while a plurality of ALC panels arranged in parallel in the thickness direction with their sides facing up are placed on the mounting table. Therefore, the above problem can be eliminated.

(Example) Fig. 1 is a perspective view showing one embodiment of the cutting device of the present invention, Fig. 2 is a plan view of the same, Fig. 3 is a front view of the same, and Fig. 4 is a perspective view showing an embodiment of the cutting device of the present invention.
The figure is a side view of the same. As shown in the figure, the mounting table 2 for the ALC panel 1 has a large number of vertically shaped plates 24 that are slightly thinner than the thickness of the ALC panel 1 arranged in parallel. is supported by a horizontal plate support 4. Each plate 24 can be raised and lowered to a desired height by a stepping motor of an electric cylinder 3 disposed at the bottom thereof and a control device (not shown). The plate receiver 4 is shaped like a letter, and its vertical tip 4a has a comb-like cavity, and a fixing plate 26 and a cylinder 25 are provided near one tip. At 26
The plate surface of ALC panel 1 can be clamped and fixed. Further, the base of the tip 4a on the opposite side of the fixing plate 26 is supported by a horizontal shaft 4b.
A hydraulic cylinder 5 provided between the bottom surface of the plate holder 4 and the foundation causes the shaft 4 to be
It can be rotated at right angles around b. The panel width cutting mechanism includes an endless band saw 22 horizontally attached to a drum 13 that is pivotally supported at both front ends of a gate-shaped pedestal 6, which is perpendicular to the width direction of the panel 1. It is becoming driven. Further, two pairs of wheels 28 are pivotally supported on the legs of the pedestal 6 and are movable along rails 29 disposed on both longitudinally outer sides of the pedestal 2. This movement is carried out by drive wheels 30, which mesh with racks provided on the lower surfaces of the rails 29 on both sides, being rotationally driven by the motor 8 via a chain 31.

Note that this mechanism is further provided with a part of a mechanism for cutting the panel 1 in the longitudinal direction.
That is, as an extrusion mechanism, an electric cylinder 11 and a stepping motor 12 that extrude a predetermined amount from the rear end of the panel 1 in the longitudinal direction are suspended on a pedestal 6 in parallel with the panel 1. It is possible to move across the entire width of the mounting table 2 in the right angle direction. Further, as a cutting mechanism, a band saw 14 is provided, which is fixed to a processing table 19 that is movable horizontally in a direction perpendicular to the longitudinal direction of the panel 1 on the side opposite to the pedestal 6, and is perpendicular to the longitudinal direction of the panel 1. .

The operation of the device configured in this manner will be described next.

First, when placing the ALC panel 1 on the mounting table 2, as shown in FIG.
The fixing plate 26 is retracted. and ALC taken out from the autoclave.
The panels 1 are transported on a transport vehicle 27 in a horizontally stacked state to just before the mounting table 2. Then, the cylinder 32 is activated to move the lowermost panel to the mounting table 2 (toward the right in the figure) in a state where the lowermost panel is slightly higher than the surface of the tip 4a of the plate holder 4. At this time, the teeth 27a on the top surface of the conveyance vehicle 27 fit into the comb-shaped gaps in the tip portion 4a. Next, the tooth 27a is lowered by the motor cylinder 32 and fixed by the fixing plate 26, and then the mounting table 2 is horizontally rotated by the hydraulic cylinder 5.

Next, the motor 8 is started to move the pedestal 6 forward in the direction of the mounting table 2, and the tip of the extrusion cylinder 11 approaches the edge of the panel 1, stops at a predetermined position, and is fixed with the rail clamp 7. Then, the motor 9 is started to move the extrusion cylinder 11 laterally to a desired position via the screw 23, and then the cylinder 11 is operated under the control of the stepping motor 12 to extrude the panel 1 by the desired size. to retreat. After the panels 1 are extruded one after another in this way, the fixing cylinder 25 is activated and the panels 1 are fixed with the fixing plate 26. Also,
The extrusion cylinder 11 reverses the screw 23 and returns it to its original position so that the movement of the pedestal 6 is not hindered.

Next, the motor 16 is started to operate the vertical band saw 14, and the processing table 19 is moved by the motor 20, so that the protruding panels 1 are sequentially cut. When cutting is completed, motors 16 and 20 stop, and motor 17
is started and the band saw 14 is retracted toward the processing table 19 and separated from the panel 1, and then the motor 20 is reversed to return the processing table 19 to its original position. After the lengthwise cutting is completed, the fixed cylinder 25 is moved back, and the cylinder 3 is then operated to raise the plate 24 to a desired size. Then, the predetermined panels 1 are successively pushed up to a desired height, and after finishing, they are fixed with the fixing plate 26.
Then, the motor 10 is started to operate the horizontal bandsaw 22, and the motor 8, chain 31, and drive wheel 3 are operated.
0, the frame 6 is advanced and the panels 1 protruding upward are sequentially cut. After cutting, cutting waste is removed, the fixing plate 26 is loosened, and the panel 1 is lowered to its original position by the cylinder 3 and plate 24, and the pedestal 6 is also returned to its original position.

The panel 1, which has been cut to length and width on the mounting table 2, is fixed again, then vertically tilted by the cylinder 5, and transferred to the transfer vehicle 27 in the reverse motion of the loading process, where it is transferred to the next process. It will be carried out.

This completes the series of operations.Although these operations may be controlled manually by a worker, the entire process may be controlled by a controller placed at a predetermined position or by a shift switch, sequential controller, etc. It can also be done automatically.

(Effects of the invention) As explained in detail above, according to the invention, the widths of a large number of ALC panels on the mounting table can be automatically cut to the desired dimensions at once, reducing work time and man-hours. has a big effect. Further, it would be even more effective if a mechanism capable of cutting in the length direction is also added.
Furthermore, if the mounting table can be tilted at right angles, panels can be transferred without using a crane, which has many effects such as saving labor and facilitating full automation.
