Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for molding fiber-reinforced hydraulic uncured irregularly shaped thin sheets for construction.

BACKGROUND ART Various noncombustible building materials have been known that are made of cement and hydraulic inorganic materials such as gypsum as main components, and are formed by adding fibrous reinforcing materials.

When molding irregularly shaped thin plates, the amount of fiber mixed should be reduced to 15 to 30% due to the dispersibility of the fibers or poor moldability.
It must be mixed in a large amount (by weight). In addition, in terms of the shape of building materials, efforts are being made to improve the quality of building materials by avoiding bent corners and using curved parts with as large a curvature as possible. In the former case, the strength and fire resistance of the product will decrease, while in the latter case, there will be major restrictions on the shape of the product. Although it can be used as a backing material, it cannot be used as a frame material for such materials.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, an object of the present invention is to provide a molding device capable of molding thin irregularly shaped plates having corner portions even when the fiber content of hydraulic inorganic materials such as cement and plaster is 8% or less. It is.

To explain this invention, a green plate forming machine is a device that makes a flat plate-like body made of hydraulic materials such as cement and gypsum as main raw materials and reinforced by mixing fibrous materials, and a green plate transporting machine is a machine for forming green plates. This device suctions and suspends the resulting uncured flat plate (hereinafter referred to as green plate) using a suction tool, and transports it to a molding machine. A molding machine is a device that turns a raw board into a irregularly shaped board with molded corners, and moves multiple upper and lower molds,
It has a mechanism that controls the movement direction and distance of the upper mold by moving the lower mold. An embodiment of the present invention will be explained with reference to the drawings. In FIG. 1, a frame 3 has wheels 4
It is suspended from the upper rail 1 by a screwdriver and reciprocates in the direction of the rail, but the driving device is not shown.
A raw board transporter 7 and an upper mold frame 16 are incorporated in the frame gate 3. The raw board transporter 7 is suspended from a vertical shaft 81 and is raised and lowered by a drive device 15, and the upper mold frame 16 is assembled into the frame 3. The frame 16 is suspended by a vertical shaft 22 and is raised and lowered by a drive device 23. A green board 10 made of a fiber-reinforced hydraulic uncured material is manufactured on the upper surface of the green board forming machine 5, is run on the lower rail 2 by wheels 6, and is stopped directly below the green board transport machine 7. . The raw board transporter 7 has a suction tool 11 on the entire lower surface of the suction box 12, and when a vacuum pump or exhaust block (not shown) is operated, the inside of the suction box 12 is sucked through the duct hose 14 and the suction duct 13. The pressure is reduced, and the suction tool 11 has a suction effect.

To transfer the raw board 10, the raw board transporter 7 is lowered by the drive device 15, and the suction box 12 is brought into a reduced pressure state with the raw board 10 in contact with the suction tool 11.
0 is attracted to the suction tool 11 and comes into close contact with it.

Next, raise the raw plate transporter 7 and move the frame 3 to the arrow A3.
2, and position it above the lower mold frame 24 as shown in FIG. Note that the suction tool 11 may have a large number of small holes or may have a mesh. In order to place the green plate 10 on the lower die frame 24, the green plate transporter 7 is lowered by the drive device 15, and when the switching damper 9 is closed with the green plate 10 in contact with the upper surface of the fixed lower mold presser 28, It leaves the suction tool 11 and rides on the fixed lower die presser 28 and the movable lower die presser 25.

This state is shown in FIG. 7, but since the raw board 10 is not supported by the entire lower surface, the raw board is soft and hangs down from the part where it is not supported. In order to prevent this, as shown in FIG. 6, a suction tool 11 is formed on the upper surface of the lower mold presses 25, 28 to create a reduced pressure state, so that the green plate can be suctioned and held. Next, the order of molding is shown in FIGS. 7 to 9.

7th. The figure shows the state immediately before molding, FIG. 8 shows the state in the middle of molding, and FIG. 9 shows the state after molding is completed. The present invention is designed to prevent harmful cracks from occurring during bending and shaping of green plates. That is, the moving distance and speed of the movable lower mold presser 25 are linked to the movable upper mold presser 18.
In FIG. 5, when the movable lower mold holder 25 is moved together with the sliding upper mold holder 20 in the direction of arrow A25 by the air cylinder 26, the cam plate 31 provided on the side of the movable lower mold holder 25 also moves in the same direction. .

On the other hand, the movable upper mold presser 18 is lowered by the cylinder 17. At this time, the guide pin 33 provided on the side surface of the movable upper mold holder 18 descends along the cam surface of the cam plate 31 while descending along the guide hole 34 of the guide plate 32 of the upper mold frame 16. As shown in Fig. 9, when the movable lower mold presser 25 moves to a predetermined position, the movable upper mold presser 18 also completely lowers to complete the molding of the green plate.The molded raw plate is suspended as it is. It can be lowered and transferred onto the roller conveyor 30.

That is, in FIG. 6, a suction tool 11 is provided on the lower surface side of the upper mold presser 18, 19, 20, and is communicated with the duct hose 14 so that the green board 10 can be lifted up. When the molding of the green plate is completed as shown in Fig. 9, the suction of the lower die pressers 25 and 28 is stopped and the suction of the upper die presses 18, 19 and 20 is activated, so that the green plate is adsorbed by the upper die. Then, the lifting frame 3 is moved horizontally as shown in FIG. 2 and transferred onto the roller conveyor 30. In addition, in the drawing, 21 is a slide mechanism, 27 is a wheel,
29 indicates a rail.
