The laminated thing is sent out in a rightwise direction in succession and a turning direction of the motor is inverted at a point of time when the laminated thing is put between the pair of feed rollers. With this construction, the laminated thing is sent out in a leftwise direction, press bonding of the laminated film 2 to the printed matter 3 is performed completely at the time when the laminated thing passes through between the pair of heating and press bonding rollers R1 and a lamination treatment of the printed matter is completed by peeling off the base material 1 from the laminated thing.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a thermocompression bonding device that presses sheets etc. while heating them, and more specifically, a recording method using a recording liquid, particularly an inkjet recording method. The present invention relates to a heat press device used for laminating a print formed by recording an image on paper or the like.

[Conventional technology]

The inkjet recording method is a recording method in which small droplets of recording liquid are deposited onto a recording material such as paper from the orifice of a recording head, and it generates little noise and does not require special fixing processing. It is attracting attention as a recording method that can perform high-speed recording and full-color image recording.

The recording liquid used in this ink jet recording method is generally formed from a recording agent such as a dye, and water as a solvent or a mixture of water and various solvents.

As described above, in the inkjet recording method, since an aqueous recording liquid is used, the recording material used for recording is required to have excellent recording liquid absorption and stability.

In particular, in multicolor inkjet recording using recording liquids of two or more colors, the amount of recording liquid that adheres to the recording material is large, so it is required that the recording liquid has particularly excellent absorption and stability. be done.

Known recording materials with such excellent properties include those in which a recording liquid receptive layer made of a porous material with excellent recording liquid absorption and stability is provided on a base material such as paper □. There is.

On the other hand, in the case of a recording material having a porous recording liquid receptive layer, the surface of the recording material lacks gloss, and even if the image is clearly recorded, it has the disadvantage of impairing the sharpness of the image when viewed with the naked eye. This has become a problem to be solved, particularly when a multicolor image is recorded by an inkjet recording method to form a color print.

As a countermeasure against this problem, it has been carried out to form an image on a recording paper using a recording liquid, and then to impart gloss to the recording surface by laminating the recording surface with a film.

Among these lamination processes, the lamination process using a peelable transfer type laminate film has the advantage that the laminate film is easy to store and easy to handle. Generally, a laminate is made by laminating a transfer layer mainly made of thermoplastic resin such as acrylic resin, polystyrene resin, polyester resin, or polyethylene resin on a base material such as paper, cloth, or plastic, so that it can be peeled off from the base material. After the film material is pressure-bonded with a transfer material in close contact with the image forming surface, the base material is separated and the transfer material remains on the recording material to impart gloss to the recording surface.

[Problem that the invention seeks to solve]

Conventionally, in a laminator used for such lamination processing, the object to be processed, for example, a laminated print and a print protection member, is inserted through an insertion slot, passed through a thermocompression roller, etc., and then outputted as is from a separate exit. Because of this structure, it was necessary to leave a certain amount of space on at least two sides, the insertion slot and the paper output slot, which limited the space available for installing the laminator.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a heat press device that can be used as a laminator, etc., which requires less installation space because the insertion port and the paper output port are integrated. purpose.

[Means for solving problems]

The above objects of the present invention are achieved by the following heat press apparatus.

That is, the present invention provides a heat press apparatus comprising a pair of heat press rollers and a pair of feed rollers that heat and press a workpiece held between the heat press rollers while rotating. This hot press apparatus is provided with a control means for controlling the rotation direction of the pair of hot press rollers and the pair of feed rollers so that the pair of hot press rollers and the pair of feed rollers reciprocate.

[Effect]

The heat press device of the present invention has excellent operability because the workpiece returns to the hand where it is inserted.

(Example) FIG. 1 shows a schematic diagram of an example of a heat press apparatus of the present invention.

In the figure, R1 is a pair of stainless steel hot press rollers with a built-in halogen heater having a radius of 15 mm, and has heating means (not shown). R2 and R3 are a pair of rubber feed rollers each having a radius of ]0+n+n, and are arranged at a center-to-center distance of #160 mm from the pair of hot press rollers. M is a motor that rotates the pair of rollers R2, R1, and R3, and has a control mechanism (FIG. 4) that reverses the direction of rotation by temporal control. This control mechanism is
As shown in Fig. 4, M repeats stopping and reversing at regular intervals under the control of a microcomputer, and is directly connected to R1, and each roller pair is interlocked, so the rotation of M, The direction is transmitted to each pair of rollers.

In the above-mentioned apparatus, the lamination process is performed, for example, in Figs.
This is done as shown in FIG.

The laminate film surface of the print protection member, which is formed by arranging the laminate film 2 as a transfer layer on the base material 1, is brought into close contact with the print material 3 as the transfer medium, and the laminate is inserted into the feed roller pair R2 (first figure). At this time, the roller pairs R2, Hl, and R3 are all rotated by the motor M so as to be sent out to the right in FIG. The laminate inserted into the pair of feed rollers R2 is fed out to the right and is sandwiched between the pair of hot press rollers R1 as shown in FIG. is crimped. Subsequently, the laminate is sent out to the right, leaves the heated press roller pair R1, and when it is sandwiched between the feed roller pair R3, the rotational direction of the motor is reversed, and the roller pairs R2, R1, and R3 start reversing. . Since the circumferential speed of the roller is usually constant, the time at which this reversal begins is stored in advance in the microcomputer. Due to this reversal, the laminate is sent out to the left, that is, in the forward path, the roller pair R2, R
The steps performed in the order of 1 and R3 are performed in the order of roller pairs R3, R1, and R2 on the next return trip. In the upper part of this return journey, the laminate film 2 is completely pressed onto the print 3 when it passes through the heat-pressing roller pair R1, and the base material 1 is peeled off from the laminate to complete the lamination process of the print.

The heat press device having a reciprocating function of the present invention can be used not only for laminating processing using a transfer-peelable print protection member as described above, but also for various processing of heat pressing sheet-like objects. can.

〔Effect of the invention〕

As explained above, since the heat press apparatus of the present invention has the same paper feed/discharge port, the installation space can be reduced.

In addition, since the object to be processed returns to the hand where it was inserted, it has excellent operability.
