(Prior Art) Generally, a decorative material such as a decorative board is manufactured by adhering a decorative paper to a base material formed of a veneer board or an asbestos cement board. Then, when the decorative paper is adhered to the base material, it is heated and pressed by a press machine in order to improve the adhesiveness thereof and at the same time dry and cure the applied adhesive.

By the way, when the base material to which such a decorative paper is adhered is heated, the adhesive may be melted and melted to the outside, and may adhere to the board fixed to the press machine to damage the gloss board. . For this reason, the heat resistant film is placed on the base material before the pressing operation so that the melted adhesive does not adhere to the board.

(Problems to be Solved by the Invention) However, since the work of placing a film on such a substrate is performed one by one by a worker immediately before a press machine which is maintained at a high temperature, it is strict. There was a problem that work efficiency was low in combination with the work environment.

Therefore, there is no problem if the film is placed on the base material at a position distant from the press machine, but in the process of being conveyed to the press machine, the film is displaced from a predetermined position and the board cannot be reliably protected, Also, as it depends on human resources,
It was difficult to improve work efficiency.

The present invention has been made in view of the above problems of the conventional art, and provides a film tacking device capable of automatically tacking and cutting a film on the front and rear ends of a substrate in sequence. is there.

On the other hand, the film F is guided to the rotatable laminating roll 5 via the first feeding device, that is, the tension roll 2, the capstan roll 3, and the expander roll 4. Then, a temporary adhesive applicator 6 is arranged above the expander roll 4, and when the temporary applicator 6 is operated, the adhesive is applied to both side edges of the inner surface of the film F. Has become.

Further, below the upper laminating roll 5, a lower laminating roll 7 is rotatably arranged so as to form a space of approximately the plate thickness of the substrate P, and these upper and lower laminating rolls 5, 7 are arranged. By rotating in the direction shown by the arrow, the substrate P conveyed by the conveying device 1 can be held and sent to the vacuum feed 8 as a carry-out device for carrying out to the next step.

Further, a second supply device for supplying the decorative paper D is provided in parallel with the first supply device for the films F, and the second supply device, that is, the tension roll.
Like the film F, the decorative paper D is guided to the rotatable upper laminating roll 5 via the capstan roll 12, the capstan roll 13, and the expander roll 14.

The decorative paper D is impregnated with a resin (adhesive), and when heated, the impregnated resin melts to become an adhesive and adheres onto the substrate P.

Further, a heat fusion device S is arranged above the rear portion of the vacuum feed 8. A first seal bar 21 provided corresponding to the rear end of P, and a second seal bar 22 provided corresponding to the front end of the next substrate P sent out through the laminating rolls 5 and 7, A cutter device 23 provided between the first and second seal bars 21 and 22, and a trailing end of the preceding substrate P carried out through the vacuum feed 8 and a laminating roll. The film F and the decorative paper D are attached to the front end of the next base material P sent out via 5, 7 and the short side of the base material P (vertical direction to the paper surface).
Then, the film F and the decorative paper D, which are continuous between the base materials P, P, are cut by heat fusion and temporary fixing.

Next, the operation of the present embodiment will be described. In the state shown in the drawings, the film F and the decorative paper D are attached to the rear end of the preceding substrate P ₀ and the front end of the next substrate P ₁ by the heat fusion device S. After being fused, the decorative paper D and the film F are cut. Therefore, one ends of the film F and the decorative paper D fed from a reel (not shown) are temporarily fixed to the front end of the base material P ₁ via the upper laminating roll 5. The film F and the decorative paper D are the first
Also, they are adhered by the adhesive discharged from the temporary application machine 6 when being supplied to the upper laminating roll 5 via the second supply device.

From this state, the vacuum feed 1 operates and the substrate P
Is carried into the laminating rolls 5 and 7, and the tips thereof are bitten, the upper and lower laminating rolls 5 and 7 rotate in the direction of the arrow, and at the same time, the vacuum feed 8 operates. As a result, the base material P is delivered by the upper and lower laminating rolls 5 and 7, while the base material P ₁ is delivered by the vacuum feed 8 in synchronization with it. Meanwhile, the front end of the substrate P ₁ from the film F and the decorative paper D is tack fixation, feeding of the substrate P and unloading of the substrate P ₁ by vacuum feed 8 by upper and lower lamination roll 5,7 Due to
The film F and the decorative paper D are sent out together with the base material P while being pressed onto the next base material P in a state where their front ends are fixed to the front end of the base material P ₁ that precedes them.

Then, when the base material P ₁ and the base material P reach a predetermined position,
The delivery of the substrate P ₁ by the vacuum feed 8 and the delivery of the substrate P by the laminating rolls 5, 7 are stopped. After that, the heat-sealing device S descends, and the film F and the decorative paper D are melt-bonded to the rear end of the preceding substrate P ₁ and the front end of the next substrate P by the seal bars 21 and 22, respectively. The film F and the decorative paper D, which are continuous between the rear end of the material P ₁ and the front end of the base material P, are cut by the cutter device 23. In this manner, the film and the decorative paper are simultaneously fused and cut at the rear end of the substrate that has been carried out first and the front end of the substrate that has been subsequently sent out.

As a result, the decorative paper D and the film F placed thereon are temporarily attached and fixed to the front and rear ends of the base material P ₁ .

Then, the base material having the front end and the rear end thereof fused and fixed with the film and the decorative paper is appropriately conveyed to a press machine (not shown), and a press operation is performed. At this time, the decorative paper D is impregnated with the resin, and the resin is melted by the pressing work to become an adhesive to bond the decorative paper D onto the base material P. Then, when the adhesive is cured and dried, it is taken out from the press and the temporarily fixed and fixed F is peeled from the base material P to manufacture a decorative plate.

In this embodiment, the film and the decorative paper were supplied at the same time, and both were temporarily attached in the process, but the decorative paper was adhered to the base material in advance and conveyed to the laminating roll. It may be configured such that only the film is sent out together with the substrate by the rotation of, and only the film is heat-sealed before and after the substrate.

(Effect of the invention) As described above, according to the present invention, it is possible to automatically temporarily and temporarily fix the films on both ends of the base material, and the positional deviation does not occur in the process of being conveyed to the press machine. It can be temporarily attached at a position distant from the machine, the work environment can be greatly improved, and the work can be automated, so that the work efficiency can be greatly improved.
