DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an insulated fireproof panel and an apparatus therefor.

[0002]

2. Description of the Related Art Conventionally, a plurality of strip-like inorganic materials have been used to manufacture an insulated fire-resistant panel formed by filling an inorganic fiber material having a fiber direction oriented in the thickness direction between two metal shells. The fiber material is conveyed by a feed conveyor in a state where the longitudinal direction and the feed direction are substantially parallel to each other, and the fiber direction is vertically oriented, and the inorganic fiber material is separated from another preceding inorganic fiber material. The inorganic fiber material was fed between the upper and lower metal shells in a state where the inorganic fiber material was abutted against the rear end of the metal fiber.

[0003]

However, in the conventional manufacturing method, when the inorganic fiber material on the feed conveyor hits the rear end of the preceding inorganic fiber material, the feed conveyor is in a horizontal state. Therefore, the inorganic fiber materials are compressed from the lateral direction and the inorganic fiber materials are bent in an arch shape and deformed, or one of the inorganic fiber materials runs on the other inorganic fiber material in many cases. In each case, the line must be temporarily stopped, and the operator has to manually correct the lifting of the inorganic fiber material and the like. Furthermore, in order to increase the strength in the thickness direction of the insulated fireproof panel,
The fiber direction of the inorganic fiber material is oriented in the thickness direction (vertical direction). Therefore, the strength of the inorganic fiber material is weaker in the lateral direction. Therefore, when the inorganic fiber material is pressed from the lateral direction. There is also a problem that warping or twisting tends to occur due to bending in an arch shape, which leads to deterioration of the quality of the product.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and it is possible to prevent the inorganic fiber material from being lifted up or run on the line and to smoothly carry the inorganic fiber material, It is an object of the present invention to provide a method and apparatus for manufacturing a heat-insulated fireproof panel capable of preventing the occurrence of warpage or twisting of a product and improving the quality of a product.

The inorganic fiber material d on the conveyor 17 is slanted against the rear end of the preceding inorganic fiber material d while flowing down, so that the inorganic fiber material d rises or climbs up as in the related art. At the same time, the occurrence of the phenomenon can be prevented, and at the same time, there is no fear that the inorganic fiber material d is bent in an arch shape, and the occurrence of warping or twisting can be prevented.

Here, a plurality of strip-shaped inorganic fiber materials are placed on the conveyor 17 from the lateral direction so that the longitudinal direction of the inorganic fiber material d and the feeding direction F of the conveyor 17 are substantially parallel. In this case, it is preferable to change the direction of the plurality of strip-shaped inorganic fiber materials d on the transport conveyor 17, and at the same time, to adjust the width of the plurality of strip-shaped inorganic fiber materials d. It becomes easy, and when the inorganic fiber material d is extruded, it can be reliably butted against the rear end of the preceding inorganic fiber material d without displacement.

A butt edge 2 between the inorganic fiber materials d
0 is preferably stepped in the width direction G of the heat-insulating fireproof panel A. In this case, it is possible to avoid that the butting edges 20 of the inorganic fiber materials d are aligned in the width direction G of the inorganic fiber material d, It is possible to prevent a portion having low bending strength from being generated in the heat-insulating fireproof panel A.

The transport of the fiber material d can be performed smoothly, and the production efficiency is greatly improved. In addition, since the floating of the inorganic fiber materials d can be prevented, the inorganic fiber materials d do not bend and deform in the shape of an arch, and warpage or twisting is unlikely to occur. As a result, it is possible to improve the quality of the product. You can do it.

A transfer conveyor 16 for transferring a plurality of strip-shaped inorganic fiber materials d from the lateral direction of the transport conveyor 17 so that the longitudinal direction thereof and the feed direction F are substantially orthogonal to each other and transporting the inorganic fiber materials d onto the transport conveyor 17 is provided. Since it is provided, it is not necessary to change the direction of the plurality of strip-shaped inorganic fiber materials d on the transport conveyor 17, and at the same time, it is easy to shift the width of the plurality of strip-shaped inorganic fiber materials d, and the inorganic fiber material d Can be reliably butted against the rear end of the preceding inorganic fiber material d when extruded. In particular, in the present embodiment, the stopper 51 is provided on the rotating portion 18 so as to be reciprocally movable in a direction orthogonal to the feed direction F of the inorganic fiber material d. By moving the stopper 51, the width of the inorganic fiber material d can be easily and accurately adjusted. Therefore, when the inorganic fiber material d is extruded by the pusher device 52, the inorganic fiber material d becomes the preceding inorganic fiber material. d can be securely butted against the rear end of the inorganic fiber material d.
It is no longer necessary to perform the width adjustment work of the inorganic fiber material d.
There is an advantage that the transfer of the sheet can be performed more smoothly.

Further, since the two pusher devices 52 are arranged so that the strokes are different in the longitudinal direction of the inorganic fiber material d, as shown in FIG. A step can be formed in the width direction G of the panel A. Therefore, it is possible to prevent the butting edges 20 of the inorganic fiber materials d from being aligned in the width direction G of the inorganic fiber materials d, and to shift the weakly butting edges 20 in terms of strength, so that the bending strength of the heat-insulating fireproof panel A is reduced. There is also an advantage that a weak portion can be prevented from occurring, and the strength of the product can be increased.
