Description

MANUFACTURED METHOD OF PREFABRICATED PANEL}

The present invention relates to a method of manufacturing a prefabricated panel used as a roofing plate or a wall plate, and in particular, to improve some of the manufacturing method (Patent application of January 15, 1999) filed by the applicant.

Generally, roof panel or wall panel is interposed between inner and outer panels made of aluminum or steel sheet or steel plate which is bent to form a shape, and interposed between foam or glass wool or urethane foam and adhering them to the sheet or aluminum sheet. I make it by a way to let In particular, in manufacturing a conventional roof panel, the roof top plate is bent and transported, and the inner panel made of a rectangular panel type styrofoam or urethane foam having a predetermined length, which is formed in advance, is transferred to a conveyor in a state of being laminated on a lamination table. The bottom plate is also transported while forming into a certain shape, but before moving into the compression roller unit, the material transfer of the roof top plate, interior material, and roof bottom plate is temporarily stopped, and a part of a separate interior material is inserted into each of the bent portions of the roof top plate and the bottom plate. Glue the inner, upper and lower surfaces, roof and lower plate by adhesive, but bond the inner and inner parts cut by a certain length to each other, and then enter the roller unit to compress the roof, the lower plate and the inner material. It is prepared by the method of coupling.

Such a conventional method for manufacturing a roof panel is laminated with a predetermined height of the foam or glass wool or urethane foam to be transported by a predetermined height, it is pointed out that the stacking stand for stacking the interior material occupies a large space of the system, The interior material is transported by the length of the interior material cut to a certain length, the productivity is greatly reduced by the interruption of work due to the temporary stop during the transfer, and after stopping the transfer of the material to be transferred to the bent roof and bottom plate By attaching a part of a separate interior material and adhering it to the contact surface of the square interior material and interior material, it compresses and compresses, which greatly reduces the productivity due to time and pause of adhesion. Interior material which performs sound absorption function by seam according to adhesion with bending groove There is a problem that brings down the quality, such as greatly deteriorating the function of.

Particularly, in the case of the conventional panel, when the outer layer part is made of metal, the metal surface is coated by a separate process to impart color. However, in this case, the cost of the coating process increases and the manufacturing process is complicated. It is pointed out that the cost of manufacturing increases and the surface is easily peeled off due to wind pressure, ambient climate, and impact, so that it is very ugly in appearance and harms the surrounding landscape.

The present invention aims to improve the productivity of the panel by greatly improving the productivity of the panel by smoothly proceeding the transfer of each material without a pause automatically and to improve the quality of the panel.

In addition, an object of the present invention is to keep the surface of the panel smooth to enhance the aesthetics, as well as to give a color to the surface of the panel to harmonize with the surrounding environment.

The present invention is a technical problem that the interior material consisting of a foam or urethane foam is made to automatically bond and compress the upper and lower plates without a seam.

In the present invention, the inner and outer plates constituting the panel are foamed by mixing pigments during extrusion and foaming, foaming using a liquid gas during foaming, or foaming by mixing foaming agents.

The present invention is a step of extruding, withdrawing, cooling and conveying the interior material consisting of a foam or urethane foam, and the stabilizer 1% by weight to 98% by weight of synthetic resin such as PVC, PE, PP, PET, ABS, EPS, PC, etc. And a mixture of 0.5% by weight of pigment and 0.5% by weight of blowing agent to convey the synthetic resin plate of the thin plate which is foamed while being extruded by extruder at high temperature, and the roof upper plate and the synthetic resin which operate by transporting the roof plate feeding roller. The sheet is bent to a certain shape by a molding machine, and 98% by weight of the synthetic resin such as PVC, PE, PP, PET, ABS, EPS, and PC, 1% by weight of stabilizer, 0.5% by weight of pigment and 0.5% by weight of foaming agent. Transfer the synthetic resin board of the thin plate to which the foamed color is mixed and extruded by extruder at high temperature, and operate the roofing plate supply roller and the roof underboard and the synthetic resin plate by a molding machine. Bending to the upper side, applying an adhesive to the inner surfaces of each of the roof top plate and the bottom plate to be transferred, and compressing the roof top plate, the interior material and the roof bottom plate by entering the unit by a compression roller, and compressing the compressed panel. Characterized in that it consists of a step of cutting and transporting to a certain length.

In the above, also in the production of the panel for wallboard is produced by the same process as the above process.
