Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for peeling off a transfer sheet in the process of producing a transfer veneer such as a cedar pattern. After dropping the hot melt adhesive 3 on the hot melt adhesive 3, the veneer 1 is fed between the sheet winding roll 4 and the pinch roll 5 from the side where the hot melt adhesive 3 has been dropped, and the hot melt adhesive 3 is applied to the transfer sheet 2.
The transfer sheet peeling method is characterized by adhering the transfer sheet to a sheet winding roll 4, peeling it off from the veneer 1, and winding it up on the sheet winding roll 4.

Conventionally, as shown in Figure 1, the transfer sheet 2 was manually peeled off from the veneer 1 by a worker, but this required two workers and could not be peeled off uniformly, resulting in sheet damage and frizz. There was a problem that poor adhesion occurred during molding.

The present invention has been made in view of the drawbacks of the conventional examples described above, and its purpose is to peel off the transfer sheet from the edge while sandwiching the veneer and the transfer sheet between a sheet winding roll and a pinch roll. The transfer sheet can be peeled off evenly, and
To provide a method for peeling a transfer sheet, which can speed up the peeling work and save labor.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. 1 is a veneer with a transfer sheet 2 attached to its surface;
A plurality of sheets are stacked and placed in front of the peeling device A. A few drops of hot melt adhesive 3 are dropped onto the edge of the transfer sheet 2 on the surface of the veneer 1 using a hot melt gun 6 just before the sheet winding roll 4.
The sheet is fed as it is between the sheet winding roll 4 and pinch roll 5 of the peeling device A. Then, the third
As shown in the figure, the hot melt adhesive 3 adheres to the circumferential surface of the sheet winding roll 4, and the transfer sheet 2 is wound onto the sheet winding roll 4 from the end.
The transfer sheet 2 is peeled off from the veneer 1. As a result, a pattern such as a cedar pattern is transferred onto the surface of the veneer 1 by the transfer sheet 2. Reference numeral 7 denotes a constant pressure cylinder that presses the sheet winding roll 4 against the pinch roll 5 with a constant pressure, and gradually rises as the transfer sheet 2 is wound around the sheet winding roll 4. Reference numeral 8 denotes a guide plate that holds down the veneer 1 and prevents it from floating up, thereby pushing the veneer 1 forward. Further, the veneer 1 may be manually pushed between the sheet winding roll 4 and the pinch roll 5, or the sheet winding roll 4 or the pinch roll 5 may be rotationally driven.

The one shown in Fig. 4 is another example of the present invention, in which the veneer must be turned over from the front to the back in order to apply glue to the back side and feed it into the spreader after the transfer sheet has been removed. In this embodiment, peeling off of the transfer sheet and reversal of the veneer are performed at the same time. That is, 9 is a detection sensor for detecting the tip of the veneer 1, 10 is a reversing guide,
11 is glue, 12 is a roll coater, 13 is a press,
14 is a roll coater insertion table, and 15 is also a table. Then, the detection sensor 9 detects the tip of the veneer 1, the hot melt gun 6 drips the hot melt adhesive 3 onto the tip of the transfer sheet 2, and the sheet winding roll 4 winds up the transfer sheet 2 and at the same time turns it over. Veneer 1 along guide 10
The veneer 1 is reversed and glue 11 is applied to the back surface of the veneer 1 by a roll coater 12, and then the veneer 1 is sent to a press 13. In this device, the hot melt gun 6 may not be used, but an automatic double-sided tape applying device 16 as shown in FIG. 5 may be used.

As described above, the present invention involves dropping a hot melt adhesive onto the edge of a transfer sheet attached to the surface of a veneer, and then feeding this veneer between a sheet winding roll and a pinch roll from the side where the hot melt adhesive was dripped. Since the transfer sheet is adhered to a sheet winding roll using a hot melt adhesive, peeled off from the veneer, and wound up on the sheet winding roll, the transfer sheet is sandwiched between the sheet winding roll and the pinch roll. It has the advantage that it can be peeled off from the edge while it is still in place, and that it can be peeled off more uniformly than a veneer, and that it does not damage the transfer sheet and cause poor adhesion during frit molding. Since it is wound up on a take-up roll, it does not get in the way. Furthermore, there is an advantage that the peeling work can be carried out quickly, improving work efficiency and saving manpower.
