Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a Finolem tacking device for tacking a film onto a base material.

(Prior Art) Firstly, decorative paper is adhered to a base material made of plywood, asbestos cement board, etc. to produce building materials such as decorative boards. When the decorative paper is adhered to the base material, it is pressed and heated by a press machine in order to improve its adhesion and at the same time dry and harden the applied adhesive.

By the way, when the base material to which such decorative paper is adhered is heated, the adhesive melts and leaks out to the outside, adhering to and damaging the glazing plate fixed to the press machine, causing damage to the base material. A heat-resistant film is placed before pressing to prevent molten adhesive from adhering directly to the glazed plate.

(Problem to be solved by the invention) However, the work of placing films on such a base material is difficult because it is carried out one by one manually by an operator right before a press machine that is maintained at a high temperature. Combined with the work environment, there was a problem of low work efficiency.

For this reason, there is no problem if the film is placed on the base material at a position away from the press machine, but the film shifts from the specified position during the process of transporting it to the press machine, making it impossible to reliably protect the glaze plate. Also, since we rely on human resources,
It was difficult to improve work efficiency.

The present invention has been made in view of the problems of the prior art, and provides a film tacking device that automatically fixes a film onto a base material and transports the film to a press machine. .

(Means for Solving the Problems) The present invention includes a base material transported via a transport device, a film supplied via a first supply device, and a method for guiding and sandwiching the film together with the base material. A laminating roll to send out, a carry-out device to carry out the base material fed out by the laminating roll, a fusing device corresponding to the rear end of the base material carried out by this unloading device, and a fusing device for the back end of the base material fed out by the laminating roll. At least a fusing device corresponding to the front end and a heat fusing device consisting of a cutting device provided between these fusing devices are provided, and the base material and the film are fed out while being pressed against the base material by a laminating roll. , further characterized in that the film is fused by a heat fusion device to the rear end of the base material carried out by the carry-out device and the front end of the base material sent out by the rattan roll, and the film is cut between them. That is.

(Function) The film is guided to a laminating roll via a supply device. Then, when the base material is conveyed to the lamination roll via the conveyance device and bitten therein, the lamination roll starts rotating, and the base material and the film are pressed against the lamination roll and sent out.

At the same time, a carry-out device provided at the rear stage of the laminating roll is activated, and the film is temporarily fixed to the front end of the laminating roll, and the base material previously sent out by the laminating roll is carried out. Then, the film is fused by a thermal fusing device to the rear end of the base material transported out by the unloading device and the front end of the base material sent out by the laminating roll, temporarily fixing the film, and at the same time, the continuous film is cut. The base material whose front and rear ends have been fused in this manner is appropriately conveyed to a press machine.

<Example) Embodiments of the present invention will be described below based on the drawings.

In the drawings, reference numeral 1 denotes a vacuum feeder as a conveying device, which conveys the introduced base material P to a pair of laminating rolls 5 and 7, which will be described later. On the other hand, the film F is guided to a rotatable upper laminating roll 5 via a first supply device, that is, a tension roll 2, a carbstan roll 3, and an expander roll 4. And above the expander roll 4,
An adhesive tack applicator 6 is arranged, and when this tack applicator 6 operates, adhesive is applied to both edges of the inner surface of the film F.

Further, a lower laminating roll 7 is rotatably disposed below the upper laminating roll 5 so as to form a space approximately equal to the thickness of the base material P, and these upper and lower laminating rolls 5, 7 rotates in the direction shown by the arrow, thereby holding the base material P conveyed by the conveyance device 1,
It can be sent out to a vacuum feed 8 serving as a carrying out device for carrying out to the next process.

Plus, these fills! - A second supply device for supplying the make-up material D is provided in parallel with the first supply device of F, and this second supply device includes the tension roll 12, the capsun roll 13, and the expander roll. 1
4, the decorative paper D is guided to an upper laminating roll 5 which is rotatable like the film F.

It should be noted that this decorative adhesive D is impregnated with a resin (adhesive), and when heated, the impregnated resin melts and becomes an adhesive, which is adhered onto the base material P.

Further, above the rear part of the vacuum feed 8, a heat fusion device S is arranged. This heat fusion device S includes a first sealer 21 provided corresponding to the rear end of a base material P0 carried out via a vacuum feed 8, and a base material P0 sent out via laminating rolls 5 and 7. ．． A second sealer 22 is provided corresponding to the front end of the sealer, and a cutter device 23 is provided between the first and second sealers 21 and 22. The base material P. A film F and a decorative film D are heat-fused to the rear end and the front end of the base material P sent out via the laminating roll 5.7 on the short side of the base material P (in the direction perpendicular to the plane of the paper). It is used to attach and temporarily fix the paper, and then cut the base material P0, the base material P, and the continuous film F and decorative paper D between them.

Next, to explain the operation of this embodiment, in the state shown in the drawing, after the film F and the decorative paper D are fused to the rear end of the base material P0 and the front end of the base material P by the heat fusion device S, , their makeup D and film F have been cut. Therefore, one end of the film F and the makeup film D that are unwound from a reel (not shown) are fused and fixed to the front end of the base material P1 through the upper laminate roll 5.

The film F and the makeup D are the first and second films.
It is bonded with the adhesive discharged from the tack applicator 6 when it is supplied to the upper lamination roll 5 via the supply device.

From this state, the vacuum feed 1 is activated and the base material P
is carried into the laminating rolls 5, 7, and when the tips thereof are bitten, the upper and lower laminating rolls 5, 7 rotate in the direction of the arrow, and at the same time, the vacuum feed 8 is activated.

As a result, the base {
While sending out the paper P, the base material P is carried out by the vacuum feed 8 in synchronization with this. By the way, the base material P.
Since the film F and the decorative film D are fused and fixed to the front end of the film F and the base material D, the film F and The cosmetics D are sent out together with the base material P while being pressed onto the base material P with their tips fixed to the front end of the base material P.

When the base material P1 and the base material P reach a predetermined position, the base material P1 is moved by the vacuum feed 8. The unloading of the base material P by the laminating roll 5.7 is stopped.

After that, when the heat fusion device S operates and descends, the base material P,
Sealpers 21 and 22 are attached to the rear end and the front end of the base material P, respectively.
The film F and the decorative paper D are fused together, and further,
The film F and the decorative film D that are continuous between the rear end of the base material Pl and the front end of the base material P are cut by the cutter device 23. In this way, the film and the decorative paper are simultaneously fused to the rear end of the base material that was carried out first and the front end of the base material that was sent out subsequently, and then cut.

As a result, the decorative paper D and the film F placed thereon are temporarily fixed to the front and rear ends of the base material P1.

Next, the base material, to which the film and the decorative paper are fused and fixed to the front and rear ends, is suitably conveyed to a press machine (not shown), and a press operation is performed. In this case, the decorative material D is impregnated with a resin, and the resin is melted by the pressing operation and becomes an adhesive to adhere the decorative material D onto the base material P. Once the adhesive has hardened and dried, it is removed from the press and the temporarily attached film F is peeled off from the base material P, thereby producing a decorative board.

In this example, the film and the decorative paper were supplied at the same time and the two were temporarily attached in the process. It may be configured such that only the film is sent out together with the base material by the rotation of the base material, and only the film is heat-sealed before and after the base material.

(Effects of the Invention) As described above, according to the present invention, the film can be automatically temporarily attached and fixed to the base material, and no positional shift occurs during the process of transporting it to the press machine. Temporary attachment can be performed at a location away from the vehicle, greatly improving the working environment, and making it possible to automate the work, greatly improving work efficiency.
