Title:
WINDING DEVICE
Document Type and Number:
Japanese Patent JP2018206571
Kind Code:
A
Abstract:
To provide a winding device capable of more surely preventing a circumference of a winding core from being unexpectedly changed by a winding and fastening force, and capable of attaining downsizing of the winding core.SOLUTION: A winding device comprises: a stationary core piece 81; a movable core piece 82; thickness measuring means which measures thickness of an electrode sheet; a circumference change mechanism 84 for changing a circumference of a winding core; and control means which controls operation of the circumference change mechanism 84. The circumference change mechanism 84 includes: a rotatable camshaft 841 including a cam part 841a of which the distance from a rotary shaft to an outer peripheral surface is not fixed; a spring 842 which provides a state where the movable core piece 82 is pressed to the outer peripheral surface of the cam part 841a in a direction of changing a distance between both the core pieces 81 and 82; and an actuator 843 to which power is supplied, thereby rotating the camshaft 841. Based on a result that is measured by the thickness measuring means, the control means controls operation of the actuator 843.SELECTED DRAWING: Figure 9
