Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention interposes a foaming reaction mixture having self-adhesiveness between a composite plate, so-called two base materials, and variously changes the position of a decorative rib of a surface material. The present invention relates to a composite plate manufacturing apparatus capable of continuously and mass-producing a composite plate in which a longitudinal edge of a surface material is formed into a box-folded shape.

[Conventional technology]

Generally, a metal hoop material is used as a surface material, and this is formed into a gutter-shaped body having an arbitrary cross section, the raw material of the synthetic resin foam is discharged, and the back surface material is laminated on it and fed to a double conveyor, and thereafter. An apparatus is known in which the above raw materials are reacted and foamed between the front and back materials to produce a composite strip having a synthetic resin foam interposed between the front and back materials, and then cut to a fixed length.

[Problems to be solved by the invention]

However, with this type of device, it is difficult to form a decorative rib on the surface material at an arbitrary position on the decorative surface, and it is disadvantageous that only one type of product can be continuously produced. In addition, when forming a box-folded portion at the edge of a wooden mouth, after cutting it into a regular size with a notch, fold the edge of the wooden mouth into a box, abut this box-folded portion, and cover the abutting portion with a sealing material before unfoaming. This is a device that discharges the synthetic resin raw material, and stacks the backing material on top of it, and cure oven, so the raw material during foaming leaks from the abutting part of the box folding part due to foaming pressure, etc. There was a defect that the surface of the folded portion was contaminated.

[Means for solving problems]

In order to eliminate such defects, the present invention feeds the surface material to the traveling cutter through each step in a continuous strip, removes the mouth end of the foam which is the core material after cutting to an arbitrary length,
Since it is the process of forming the box-folded part, it can be manufactured at high speed without polluting the decorative surface and the surface of the box-folded part, and a decorative rib with an arbitrary width and depth can be placed at any position on the decorative surface of the surface material. It is an object of the present invention to propose a composite plate manufacturing apparatus capable of continuously manufacturing, in a line, a composite plate that can be formed and has excellent design characteristics.

Next, the operation of the composite plate manufacturing apparatus according to the present invention will be described. That is, 0.27 wound around the uncoiler 3 in a coil shape.
A color steel plate having a thickness of mm is mounted with the decorative surface side as the upper surface, and is fed to the first loop portion 7 via the pinch roller 4. Next, the surface material A is passed through the first loop portion 7 and then the first preheater 9
Heat to 30 ℃ ~ 60 ℃, soften the decorative coating film to a predetermined hardness, and continuously form an embossed pattern consisting of concave parts α and convex parts β with embossing roll 10 as shown in FIG. To do. After that, surface material A is tensioner 11 and leveler 1
4. Through the pinch roller 13, the side edges in the longitudinal direction, which are generated at the time of embossing, are stretched, and the distortion caused by the fact that the central portion of the decorative surface is not stretched so much is removed, and the sheet is fed to the reversing section 15 . The surface material A passes through the second loop portion 18 and then the pinch roller 19
It is fed to the primary molding machine 21 as shown in FIG. 6 via the, and the decorative rib a is formed on the surface material A as shown in FIG. 7 (e). The surface material A on which the decorative rib a is formed is fed to the secondary molding machine 22, and both ends of the surface material A are molded as shown in FIG. 9 (e), and the molding of the surface material A is completed. The surface material A, which has been molded and has a concave cross-section, is then processed by the second preheater 9a.
Immediately after heating to about 30 ° C to 110 ° C, as shown in Fig. 11 (a), on the back surface of the backing material B made of aluminum kraft paper continuously supplied from the backing material supply section 26 , The mixture P made of unfoamed polyisocyanurate foam is discharged, laminated on the concave portion of the surface material A by the guide roller 23a, and fed to the cure oven 28 . Cure oven 28 is a heating source
The surface material A, the back surface material B, and the mixture P are preliminarily heated to an atmosphere of 90 ° C. by 35 to be bonded and hardened integrally, and are delivered as a continuous strip composite plate S from the outlet 28b. Next, the composite plate S that is continuously sent out is 3030 mm
Then, as shown in FIG. 12, the composite plate S is cut to form box folds A ₂ at both ends in the longitudinal direction. In this case, as shown by the chain double-dashed line in FIG. 12, the back material B and the mixture P are cut and cut at the same time. Cut composite plate S
Is fed to the box folding section 39 by a conveyor 38 composed of a belt conveyor, and as shown in FIGS. 13 (a) to 13 (c), a backing material B, a mixture P cutting step, a folding mark making step, and a bending step. After that, both end surfaces in the longitudinal direction of the composite plate S are covered with the box fold pieces A ₂ , and the composite plate S is completed. After that, it is sent to a packing unit (not shown).

[Other Examples]

The above description is merely one example of the composite plate manufacturing apparatus according to the present invention. The embossing roll 10 is provided at the position shown by the alternate long and short dash line in FIG. 1, and various embossing patterns are applied by a plurality of embossing rolls 10. It is also possible to use a device corresponding to a plurality of types of embossed patterns. It is also possible to install a caulking material discharger 40 between the curing oven 28 and the traveling cutter 37 as shown by the dotted line, and to implant the caulking material C as shown by the diagonal lines in FIG. 15, for example. In addition, caulking material C
Examples of the hot-melt adhesive include hot-melt adhesives (including foams of 2 to 5 times), rubber-based and synthetic resin-based packing materials adhered with an adhesive, or swellable water-absorbent resins. . Further, as shown by the alternate long and short dash line in FIG.
By providing b, the back surface material B can be heated, or the back surface material B can be heated by hot air in the curing oven 28 . Also,
It is also possible to form a heat retaining part only in the cure zone after the cover 36 as shown by a chain line. In addition, the box-folded portion may be formed as shown in FIG. 16, or when the surface material A is 1000 mm, it may be slit by the carrier 38 to be two members. Furthermore, when feeding the surface material A one coil at a time, it is not necessary to connect two uncoilers 3 and two pinch rollers 4 in series, and it is possible to use a single system.

〔The invention's effect〕

As described above, according to the composite plate manufacturing apparatus of the present invention, since a constant tension is applied to the coil during embossing, the uneven pattern does not shift during embossing, A beautiful uneven pattern can be formed.
Residual strain during embossing can be easily removed by passing it through a tensioner or leveler, so there is no peking or twisting. Since the mixture is sandwiched between the front and back materials to form a composite plate, which is cut and then folded in a box, the decorative surface of the composite plate is not contaminated.

Since the primary molding machine for forming the decorative ribs and the secondary molding machine for molding the male and female fitting parts have separate molding functions,
The position of the decorative ribs can be changed variously, and a composite plate having a plurality of decorative surfaces can be easily and mass-produced with one line. There are features such as.
