Description of the invention (8) / Figure 2 shows that the first winding axis 5 is on the winding completion side, while the second volume When the take-up shaft 7 is on the winding start side, the first take-up shaft 5 position is on the take-up start side, and the second take-up shaft 7 position is on the car winding end. In the case of the take-up, the take-up completion side torque setting section 17 The series conversion is connected to the drive circuit 3 1 of the motor 9 of the second take-up shaft 7 », and the series conversion of the winding start-side torque setting unit 19 is converted to the moving circuit 29 of the motor 11 of the first take-up shaft 5. In the above embodiment, by the control timing, the timer implements the control of the declining of the output torque of the motor on the winding completion side and the control of the gradual increase of the output torque of the motor on the winding start side, but the control is an input traverse type cut It is also possible to implement the feedback compensation method based on the position of the cutter for the position information of the cutter 13; the specific control system is not specifically controlled by the timer. [Effects of the Invention] As can be seen from the above description, according to the tension control method and device of the two-axis winder according to the present invention, when the film sheet is cut by the traverse cutter, the motor on the winding completion side is gradually reduced. The output torque, and the output torque of the motor of the take-up shaft that starts winding is gradually increased. Therefore, neither of the take-up shaft on the winding completion side and the take-up shaft on the winding start side will cause the film to be wound. The pulling force becomes too large, so it can avoid the damage of the film sheet on the side where the winding is completed, and the occurrence of creases, creases, shrinkage, etc. on the film sheet on the side where the winding starts. Thereby, the occurrence of defective products can be avoided, and it becomes possible to efficiently and efficiently perform the film winding on the film manufacturing line continuously. In addition, by cutting the film sheet, the winding side of the winding motor is completed-this paper standard is applicable to China National Standard (CNS) A4 specification (210X297mm) ~ (please read the precautions on the back before filling in this Page) Binding · Order

Invention description (9) / Decrease control of output torque / Increasing control of output torque of the motor of the take-up shaft at the start of winding When the sum of the output torque of the motor on the take-up shaft on the completion side and the output torque on the take-up shaft on the take-up side is kept at a certain value, the tensile force acting on the film in cutting the film Keeping it at a certain value, even if either of the winding axis on the winding completion side and the winding axis on the winding start side can more surely prevent the film winding force from becoming too large, so it is more sure to avoid the winding There is damage to the film on the completion side, and there are creases, creases, flaws, etc. on the start side of the winding. It is born on the film. [Brief description of drawings] Fig. 1 is a schematic configuration diagram showing an embodiment of a two-spool winder to which the tension control device according to the present invention is applied. Fig. 2 is a block diagram showing an embodiment of a tension control device of a two-axis winder according to the present invention, and Fig. 3 is an output of a motor of a winding shaft on a winding completion side when a film sheet is cut A graph of torque and the change characteristics of the output torque of the motor of the winding shaft on the winding start side.
