Abstract

PURPOSE:To improve the accuracy of an alignment of pattern by arranging a transfer conveyor and an endless running body with a pad piece abutting on a laminate board to allow the formation of an uneven pattern on a synthetic resin layer on the laminate board as accurately positioned with a ground pattern thereof. CONSTITUTION:In the laminating of a laminate board 2, a fancy paper 8 is stuck on a wood or metal substrate 3 to apply a ground pattern 5 on the substate 3 while a light transmitting synthetic resin layer 4 is adhered onto the top surface thereof. An endless running body 7 comprising a roller body and, for example, a tile pattern is formed on the circumference thereof. An uneven pattern 9 with ridges 33 arranged in a lattice is formed. The laminate board 2 being fed with a dog 30 as laid on a transfer conveyor 6 having one end rim (a) thereof ahead with the synthetic resin layer 4 upward while being guided with a guide roller 31 abbuts against a pad piece 12 of the endless running body 7 having the pad piece 12 positioned facing the upstream of the transfer conveyor 6 as the one end rim (a) of the substrate 3 advancing. Thereafter, as the laminate board 2 proceeds, the endless running body 7 is driven to rotate to form a convex-concave pattern 9a positioned with the ground pattern 5 on the synthetic resin layer 4 with the convex-concave pattern 9. Thus, a tile uneven pattern P is formed.

Description

[Detailed Description of the Invention] [Technical Field J] The present invention provides an uneven pattern that enables accurate formation of an uneven pattern on a transparent synthetic resin layer on the upper surface of the substrate in accordance with the base pattern formed on the substrate. This invention relates to a plate forming device.

For example, as shown in Fig.
On the top surface of the substrate 3 which has been subjected to pattern 1! Translucent synthetic resin that formed pattern 9a*
By stacking 4, the strip 1f3 of the uneven pattern 9a is formed.
It is conceivable to form a tile plate-like uneven pattern board P with a novel design in which the base pattern 5 emerging from the base pattern 10 functions as a joint pattern of tiles, for example. However, when producing such an uneven pattern board P, it is difficult to form the uneven birch 9a on the synthetic resin scrap 4 to be laminated on the substrate 3 in alignment with the base pattern 5.

[Purpose of the invention]

The present invention has a transfer conveyor and an endless running body provided with a contact piece that comes into contact with the laminate plate, and is capable of forming an uneven pattern on the synthetic resin m on the laminate plate that is precisely aligned with the underlying pattern. The purpose of the present invention is to provide a molding device for a plate with an uneven pattern.

[Disclosure of the invention]

Hereinafter, an example will be described based on the drawings, taking as an example a case in which the molding apparatus 1 for a concavo-convex pattern board of the present invention is used to mold a concave-convex pattern board P having a tile pattern as illustrated in FIG. .

In the figure, a molded plate W with a concave-convex pattern 1 is attached to a transfer conveyor 16, and an endless running body 7 having a concave-convex pattern 9 on the outer peripheral surface and a protruding abutment piece 12- is attached to the transfer conveyor 16. In this case, the endless running body 7 is formed in a roll shape.

The transfer conveyor 6 includes a pair of roller conveyors 23.24, in which free rollers 21a, -122a, etc. are arranged in parallel between the side frames 21.21.22.22, and are arranged in parallel with a small gap.
and a chain conveyor 29 in which chains 27, 27, 27 are passed between chain wheels 25, 25, 25, 26, 26, 26 which are pivotally supported at the front and back of the outer surface of the side frame 21, 22 including the small gap. A dog 30-. provided in the same phase as the chain 27-. pushes the laminated plate 2 placed on the upper surface of the roller conveyor 23.24. Furthermore, guide rollers 31 are arranged in parallel on each of the outer side frames 21 and 22.
As shown in FIG. 4, the F4 temporary 2 has a base pattern 5 applied to the substrate 3 made of wood or metal by pasting decorative paper 8 on the substrate 3, and a translucent layer on the upper surface. Synthetic resin scraps 4 made of synthetic 4δ1 resin having the following properties are adhered and laminated. Also, the base pattern 5 is separated from one end edge a of the substrate 3 by its starting line, for example, by half the pitch length of the grid, F31 [
The base pattern 5 is formed in advance as shown in FIG. The base pattern 5 can be formed directly on the substrate 3, and the synthetic ff1f resin forming the synthetic resin layer 4 may be made of polypropylene, polystyrene, polyvinyl chloride, acrylic resin, polycarbonate, polyamide 1', etc. In addition to thermoplastic resins, thermosetting resins such as urea resin, melamine resin, and polyester resin can also be used, and the thickness of the synthetic resin W34 is set depending on the depth of the uneven pattern 9a.

The endless running body 7 consists of a roller body as described above,
The upper ends of the support columns 32 and 32, which stand between the transfer conveyors 1 and 6, are supported perpendicularly to the transfer conveyor 6, and the outer circumferential surface of the support columns 32 and 32 are vertically and horizontally provided with protrusions 33 forming, for example, a tile pattern. An uneven pattern 9 arranged in a grid pattern is formed. Further, on the outer circumferential surface, for example, three contact pieces 12, 12, 12 are protrudingly provided, which divide the outer circumferential surface into three equal parts and stand up at intermediate positions of the horizontal protrusions 33,33. The contact piece 12 is formed to have a height IIr higher than the protrusion 33 and can come into contact with the substrate 3 of the laminated plate 2 conveyed on the transfer conveyor 6, while the protrusion 33 of the uneven pattern 9 The height of the endless running body 7 is set to a height that allows it to mesh with the synthetic resin layer 4. The endless running body 7 can also be configured as a hot roll that heats the outer circumferential surface by storing a heater inside or circulating a heating medium. It facilitates molding, and when a thermosetting resin is used, its curing can be accelerated.

Then, the dog 3 is placed on the transfer conveyor 6 with the synthetic resin W4 on top and one end edge a in front and guided by the guide roller 31.
The MR plate 2 sent by the conveyor 6 has one contact piece 12 on the endless traveling body 7 located on the upstream side of the transfer conveyor 6.
The abutment piece 12 and one end edge a of the substrate 3 first come into contact with each other.

After that, as the laminated plate 2 advances, the endless running body 7 is rotated in a driven manner, and the uneven pattern 9 is bitten into the synthetic resin Jtif4, so that the base pattern 5 is aligned with the synthetic resin JFf4. Therefore, it is possible to form a tile-like uneven pattern Fj, P that makes the lower pond pattern 5 stand out from the grooves lO. When one laminated plate 2 finishes passing, the endless traveling body 7 directs the contact piece 12 toward the upstream side of the transfer conveyor 6, stops again, and waits for the next laminated plate 2 to be supplied. Note that the synthetic tree BNJFi4 is supplied to the transfer conveyor 6 in an uncured or semi-cured state.

FIG. 3 shows another embodiment of the present invention in which the endless running body 7 is not shaped like a belt.

The endless running body 7 has a rack 1 which is passed over pulleys 35 and 36.
"It is an endless belt body, and its outer circumferential surface has, for example,
A concavo-convex pattern 9 forming a pine-like shape is formed, and the abutment pieces 12, 12, 12 protruding outward are formed at intermediate positions between the lateral protrusions 33, 33. The transfer conveyor 6 is arranged on the entrance side of the endless traveling body 7 and is connected to the endless traveling body 7.
A feeding section 37 consisting of a roller conveyor which has a gap equal to or more than the thickness of the laminate 2 between it and the outer circumferential surface of the laminate 2, and a synthetic resin layer of the laminate 2 disposed on the exit side and in the uneven pattern 9 of the endless running body 7. 4
A holding part 39 using a roller conveyor is installed in parallel to separate the gap between the feeding part 37 and the holding part 39.
A passing roller 40 of intermediate height is provided in between, and receiving rollers 41--., which support the endless traveling body 7 from above, are arranged in parallel above the presser portion 39. The contact piece 12 projects with a gap in the direction 11 of the endless traveling body 7, and the roller conveyor 39 is provided with a groove 42 through which the corresponding piece 12 passes. Therefore, the synthetic resin layer 4 is placed on the transfer conveyor 6.
l! One end edge a of the laminate 2 that is carried by one person comes into contact with the contact piece 12 of the endless traveling body 7 that is circulating, and after moving through the feeding section 37, it passes through the passing roller 40 and moves to the presser section 39. As a result, the uneven pattern 9 of the endless running body 7 is synthesized 411 n
NN13 interlocking, the synthesis +31 fat waste 4 and its uneven pattern 9
is transferred, and since the contact piece 12 contacts one end edge a,
The uneven pattern board P can be formed while correctly aligning the base pattern 5 and the uneven pattern 9.

[Results of invention]

As described above, the apparatus for forming a concave-convex pattern board of the present invention includes an endless running body having a concavo-convex pattern and a contact piece formed on the outer circumferential surface of the conveying machine 1, and stacks W on the said contact piece. By bringing the slopes into contact with each other, the laminate can be synthesized while aligning the base material Iφ and the uneven pattern.■1 The uneven pattern can be transferred to the fat layer, improving the alignment and U accuracy of the underlying pattern and the uneven pattern. At the same time, it can produce excellent effects such as greatly improving the production size of the uneven patterned plate. Note that the uneven pattern plate forming apparatus of the present invention can be used for forming various appropriate uneven patterns in addition to tile materials.
It can also be used to produce a textured patterned board in which the design effect is enhanced by having the textured pattern shifted from the base pattern rather than directly above it.
