Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for peeling a transfer sheet from a veneer, and includes a drive roll that is rotationally driven;
A veneer with a transfer sheet, on which a transfer sheet has been pasted, is passed between the drive roll and a take-up roll which is disposed above the drive roll so as to be able to move up and down and freely rotate, while being pinched between the two rolls. This method is characterized in that the transfer sheet is wound up on a winding roll.

Conventionally, artificial precious wood has been manufactured in the following manner. As shown in FIG. 1, first, an adhesive is applied to the surface of a thinly sliced veneer 5, and then a transfer sheet 3 with ink printed on the lower surface is pasted to the surface of the veneer 5 and pressed. Next, the transfer sheet 3 is peeled off and printing 6 is performed on the surface of the veneer 5.
Transfer the pattern. Next, a large number of these veneers are laminated with adhesive and pressed again to form a frit. Thereafter, the fritsch is thinly sliced again to obtain artificial wood with the grain of cedar, pine, etc. By the way, when peeling the transfer sheet 3 from the veneer 5, conventionally two workers peel off the transfer sheet 3 from both ends of the veneer 5, as shown in FIG. However, there is a problem that the transfer sheet 3 cannot be peeled off uniformly in this way, and the transfer sheet 3 is easily damaged during peeling.
When the fritches were manufactured using this method, there was a problem in that poor adhesion occurred. In addition, two or more workers are required,
Moreover, there was also the problem that it took a long time to clean up the transfer sheet 3 after it was peeled off.

The present invention has been made in view of the above points, and is capable of uniformly peeling the transfer sheet so that it does not remain on the veneer, and can be automatically peeled off from the veneer. The object of the present invention is to provide a transfer sheet peeling method.

The present invention will be explained in detail below with reference to Examples. As shown in FIG. 3, the drive roll 1 is disposed horizontally within the main body 7 of the apparatus, and is connected to a drive motor 8 by a belt 9 and driven to rotate. Above the drive roll 1, there is a winding roll 2 formed by covering the shaft core 10 with a paper tube 11, or an opening 3 cut out in the side plate of the device main body 7.
5, and is arranged so as to be able to move up and down and rotate freely. Winding roll pressing cylinders 12, 12 are arranged above both ends of the winding roll 2, respectively, and the winding roll 2 is moved upward while being pressed downward in synchronization with the rotation speed of the winding roll 2. In this way, the take-up roll 2 can be pressed against the outer peripheral surface of the drive roll 1 at a constant pressure. In addition, this winding roll pressing cylinder 1
2 may be configured so that it can be elastically pressed downward by air pressure or the like. In the figure, 13 is a drive switch for the drive motor 1, and 14 is a vertical movement switch for the take-up roll pressing cylinder 12.

Therefore, when the transfer sheet 3 pasted when transferring ink to the back surface of the rotary veneer 5 etc. is subsequently peeled off from the veneer 5 using the above-mentioned device,
As shown in FIG. 4, a veneer 4 with a transfer sheet is inserted between a drive roll 1 and a take-up roll 2. The transfer sheet-attached veneer 4 at the beginning of passing is used to attach the transfer sheet 3 at the tip to the paper tube 11 of the winding roll 2. The winding roll 2 is pressed downward, and the veneer 4 with the transfer sheet is passed between it and the drive roll 1 while being pressed, and the winding roll 2 is pressed against the upper surface of the veneer 4 with the transfer sheet being sent. The transfer sheet 3 is rolled in pressure contact with the transfer sheet 3 and rolled up. The front and rear veneers 4, 4 with transfer sheets are connected by pasting tape 14 on their upper surfaces as shown in FIG. The transfer sheet 3 of the transfer sheet-attached veneer 4 is wound up following the previous transfer sheet 3, so that the transfer sheets 3 can be continuously peeled off. After winding the transfer sheet 3, as shown in FIG. It is easy to process and store.

As described above, in the present invention, a veneer with a transfer sheet to which a transfer sheet is attached is passed between a drive roll and a take-up roll while being pressed between both rolls, and the transfer sheet is passed onto the take-up roll. Since the transfer sheet is rolled up, the transfer sheet can be peeled off uniformly from the veneer without damaging the transfer sheet or leaving unpeeled transfer sheet on the veneer. Fritsch processing can be performed without any problem on the veneer to which the ink has been transferred. Furthermore, this device allows the transfer sheet to be automatically and continuously peeled off, resulting in labor savings.
