Title:
WINDING DEVICE CAPABLE OF MEASURING WINDING PROCESS REAL TIME PRECISE TENSION
Document Type and Number:
Japanese Patent JP2023121746
Kind Code:
A
Abstract:
To provide a winding device capable of measuring and monitoring a tension value occurring during a winding process of a substrate (an electrode plate and/or a separation membrane) having a short width and a low tension in real time and precisely and allowing a winding process real time precise tension measurement synchronized dynamically with the measured tension value of the substrate and a winding speed of the substrate.SOLUTION: A winding device comprises a control part for determining a winding speed corresponding to a tension profile of a substrate to be wound and outputting a motor control signal corresponding to the winding speed, an electric motor for rotating a winding core to wind the substrate up by the motor control signal and a tension sensor installed at a transfer roller for transferring the substrate wound up to the winding core and sensing a tension value of the substrate in real time and precisely and providing the tension value to the control part, and the control part controls the winding speed of the electric motor dynamically by utilizing the tension value.SELECTED DRAWING: Figure 1
