Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for continuously manufacturing composite boards used as exterior materials for buildings.

(Prior art) As shown in Japanese Patent Publication No. 59-17675, the conventional technology involves forming a thin metal plate to form a surface material with a flat decorative surface, and discharging an unfoamed synthetic resin raw material into the concave portion of the surface material. ,
There is an apparatus for manufacturing a composite plate in which a back material is laminated thereon and the material is continuously manufactured into a predetermined shape via a caterpillar type or steel belt type mold member.

(Problems to be Solved by the Invention) Conventional devices can only be used when the decorative surface of the surface material is a flat surface;
There was a drawback that it could not be manufactured if there was a difference in level. Further, although it is possible to manufacture a composite plate with an inclined decorative surface using a caterpillar type material, the manufacturing speed is as slow as 5 to 10 m/min, which has the disadvantage of poor productivity.

(Means for Solving the Problems) In order to solve these problems, the present invention transports the surface material immediately after forming with a conveyor that matches the decorative surface, and transfers it to a roller that matches the cross section of the composite board. The core material interposed between the front surface material and the back surface material is foamed in a curing oven consisting of a group of sheets, and the core material is formed into one piece.Then, this continuous band is cut into regular lengths with a traveling cutter to produce a large amount of material at high speed. It is configured to be able to manufacture composite plates.

(Function) According to this configuration, the surface material made of a thin metal plate is formed,
This facing material is guided in a line contact state by a group of rollers, then a core material is supplied to the back side of the facing material, and with the backing material laminated on top of it, the thickness is regulated while being conveyed and heated. This is for cutting a continuous band into regular lengths.

Note that one of the conveyance rollers 7 and 8, the conveyance roller 7 having a larger diameter, is driven, and either the conveyance roller 8 has a free roller structure, or both rollers have a free roller structure. In addition, regulation roller 9.10
．． 11 is a roller with an outer shape corresponding to the end face shape of the surface material 35 as shown in FIG. Further, the conveying roller 7.8 and the regulating roller 9.10.11 are used to control the displacement of the surface material 35.
The rollers are arranged alternately in the traveling direction of the rollers, or in multiple stages so that the rollers do not face each other. The discharge machine 14 serves as the core material 37 of the composite board 38, and applies, for example, a foamable reaction mixture P (hereinafter simply referred to as a mixture) having self-adhesive properties to the back surface 35c (one surface) of the surface material 35, for example, by applying a rotary blade body. It is intended to be supplied by any one of the following methods: a discharge method equipped with an air conditioner, a spray gun method (air, airless), or an injection method. Note that as the mixture P, a thermosetting foamable synthetic resin is used. The guide roller 15 is the back material 36
The discharged mixture P is guided onto the concave portion of the laminated surface material 35, and the supporting position is moved up and down or back and forth to cover the mixture P in accordance with the reaction system of the mixture P, and the mixture P is moved like a nip roller. It is an extension of the Its structure is that the upper guide roller 15a is cylindrical and the lower guide roller 15 is cylindrical.
