Description

[Detailed description of the invention] The present invention is a laminator for sealing sheets between thermoplastic plastic films or between thermoplastic plastic films and other sheet-like bodies, and more specifically, for sealing unnecessary parts of laminated plastic films. This invention relates to a laminator having interlocking cutters that automatically cut.

The laminator is used to preserve photos, documents, and the like. The laminators currently in use can be roughly divided into those that continuously supply long plastic films and laminate them continuously, and those that press individual commuter passes, membership cards, etc. using molds.

The former type is suitable for continuous lamination in large quantities. However, in the latter case, a manual process is required to cut off unnecessary parts of the continuous process and process it to a predetermined size. FIG. 1 is an explanatory diagram showing the process of continuous lamination. In the figure, P1 and P2 are thermoplastic plastic films, and S1, S2, and S3 are sealed objects. Usually, the thermoplastic plastic film is sold in standard widths, and unless it is consumed in large quantities, it is not supplied in the desired width. Therefore, as described above, after the continuous lamination process, the sheets are cut along the lines AA, B-B, and C-C shown in FIG. 2 using a manual cutter or the like. This work is done manually, and the labor cost of this work is one of the causes of the increase in the unit price of laminating.

An object of the present invention is to provide a laminator having interlocking cutters that can greatly simplify the cutting process after the lamination process of the continuous laminator.

In order to achieve the above object, the laminator with interlocking cutters according to the present invention is equipped with a pair of press rollers and a pair of pull-out rollers, and the laminator is equipped with a pair of press rollers and a pair of pull-out rollers to continuously pass sheets between thermoplastic plastic films or between a thermoplastic plastic film and another sheet-like body. In a laminator for sealing, a sheet insertion guide is provided on a sheet guide stand so as to be movable at right angles to the sheet insertion direction, a thin blade-shaped cutter, and the cutter is laminated between the press roller and the pull-out roller. A cutter holder is supported so as to face the plastic film path and is movable in a direction parallel to the moving direction of the insertion guide, and the cutter holder supports the insertion guide and the cutter holder, and an interlocking mechanism that is connected so as to be movable by an equal amount in the same direction.

According to the above configuration, at least unnecessary portions on the sides in the lamination direction can be automatically cut off, so that the cutting process after the lamination process is completed can be greatly simplified.

Hereinafter, the laminator having interlocking cutters according to the present invention will be described in more detail with reference to the drawings.

Next, the operation of the apparatus having the above configuration will be explained in detail together with the detailed configuration. When starting to use the device,
Remove knob 105 and knob 106 in the state shown in FIG. The knob 106 is the upper pull-out roller 11 mentioned above.
The knob 105 is a knob for adjusting the pressure between the upper press roller 9 and the lower press roller 10. The knob 105 is likewise connected to the camshaft of the device for regulating the pressure between the upper press roller 9 and the lower press roller 10. When knob 105 and knob 106 are removed, upper covers 101 and 102 can be expanded to the left and right relative to lower covers 103 and 104, respectively.

As shown in Fig. 4, the upper cover 102 is provided with operation knobs for switches and temperature adjustment, but the wiring from these to the lower assembly etc. should be done with plenty of time on the premise of the above expansion. ing.

Next, a coupling mechanism (not shown) between the upper and lower assemblies is loosened, and the upper assembly is raised at a substantially right angle. With the upper assembly unfolded approximately 90 degrees from the lower assembly, films P1 are transferred from the upper film roll 3 and the lower film roll 4 supported by the upper film roller shaft 1 and the lower film roller shaft 2, respectively.
Pull out film P2. On the upper assembly side, the film P1 is applied to the upper idle roller 6, the upper heating roller 7, the upper press roller 9, and the upper pull-out roller 11 in this order. On the lower assembly side, the film P2 is applied to the lower idle roller 6, the lower heating roller 8, the lower press roller 10, and the lower pull-out roller 12 in this order.

Then, return the upper assembly, connect the upper assembly and the lower assembly, and attach the upper covers 101 and 102 to the fourth
Return the upper and lower heating rollers 7 to the positions shown in the figure,
8. When the upper and lower press rollers 9 and 10 are heated to a predetermined temperature by the built-in heater, preparation for lamination is completed.

Before starting the device, rotating a predetermined roller, and inserting the sheets to be sealed, determine the position of the insertion guide 34 with respect to the guide table 37, and determine the position of the sheet to be sealed inserted from the guide table 37. Determine the insertion reference position for one edge. When the position of the insertion guide 34 is determined, the position of the cutter holder 35 is automatically determined. Note that the position at which the film P1 and the film P2 are cut from the sealed sheet differs depending on the use and the like. This adjustment is performed using the cutter holder 35.
By adjusting the position of the cutter 36 relative to the cutter 36, the amount of cutoff can be adjusted.

The apparatus is started and one edge of the object to be sealed, such as a photograph, is sequentially fed from the front so that it comes into contact with the guide 34. The objects to be sealed, such as photographs, are film P heated by upper and lower heating rollers 7 and 8, respectively.
1. The film P2 is pressed and sealed between the upper press roller 9 and the lower press roller 10.

At this time, the cooling fan 40 is operated, and the upper drawer roller 11 and the lower drawer roller 12 cool the paper during the drawing process. While being cooled or being cooled, one edge of the film is cut into a cutter 36 during the conveyance process as shown in FIG.
The paper is cut into pieces by the upper pull-out roller 11 and the lower pull-out roller 12 to be pulled out of the apparatus.

It can be said that the cooling fan 40 contributes to making the device more compact. When the film is pressed by the upper press roller 9 and the lower press roller 10, the film is in a soft state and is difficult to cut before cooling. The cutter is forcibly cooled by the cooling fan 40, so the upper press roller 9
This makes it possible to perform sufficient cutting without placing the roller at a distance from the lower press roller 10.

Since the laminator according to the present invention is configured and operates as described above, it has the following effects.

Place the insertion guide 34 and cutter holder 35 into the cutter holder 3.
5 are connected by an interlocking mechanism that allows them to move by an equal amount in the same direction as the movement direction of the insertion guide 34, so once the position of the insertion guide 34 is determined, the cutter holder 35
The position of is determined automatically. Therefore, if the operator determines the position of the insertion guide 34 before starting a series of operations and inserts the object to be sealed along the insertion guide 34, one edge of the film will be automatically cut as shown in FIG. be done. As a result, the cutting process is greatly streamlined because the operator only has to cut between the sealed sheets. Note that manual cutting between sheets is easier than cutting in the longitudinal direction and does not require skill.

Various modifications can be made to the embodiments described in detail above within the scope of the present invention. In the above embodiment, only one cutter is used, but it is of course possible to provide two cutter insertion guides and cut both edges.
