Embodiment Construction

[0029] Based on the invention figure 1 with figure 2 In the electrode winding device 1 shown, the strip-shaped positive electrode side electrode 2 and the negative electrode side electrode 3 and the strip separators 4 and 5 for insulation to be sandwiched between the pair of electrodes 2 and 3 are removed from the corresponding coils. The discs 6, 7, 8, 9 are sent out, and are guided between a pair of nip rollers 10 by a plurality of guide rollers 11, 12, 13, 14, and floating rollers (not shown) provided as necessary, and pass The pair of nip rollers 10 are finally wound on the outer peripheral surface of the core 38.

[0030] When necessary, a pair of nip rollers 10 are arranged near the finished product winding position S in such a way that at least one of the nip rollers 10 can contact and be separated from the other.

[0031] Each electrode 2 or 3 passes in front of the electrode holder 23 or 24, the pair of electrode cutters 25 or 26, and the defective electrode winding devic...

Abstract

In an electrode winding device, when a defect mark is detected, a defective portion of an electrode can be separately wound and discarded as a defective electrode. The electrode winding device comprises: a pair of openable and closable chucks (33) used for winding a defective electrode; an operation driving unit (39) for opening and closing the chucks (33); a rotationally driving unit (40) for rotating the chucks (33); and a reciprocating drive means (41) for reciprocating the chucks (33) between a standby position and an operating position. The electrode winding device operates as follows: when a defective electrode is discarded, the chucks (33) is moved by the reciprocating drive means (41) from the standby position to the operating position; at the operating position, the chucks (33) are closed by the operation driving unit (39) to hold the defective electrode therebetween; the chucks (33) are rotated by the rotationally driving unit (40) to wind the defective electrode around the outer circumference of the chucks (33); and then the wound defective electrode is discarded from the chucks (33).

Description

Technical field [0001] The present invention relates to a device for winding and discharging defective electrodes in an electrode winding device, which manufactures electrodes for batteries or accumulators by winding a strip electrode and a separator together. Background technique [0002] For example, in a storage battery, a pair of (positive and negative) electrodes are provided in a case in a state of being wound on a core (winding core). A pair of electrodes are wound on the core to a desired length with the separator sandwiched, and then cut into a finished unit. [0003] If a defect occurs in the electrode during the manufacturing of each electrode, a label or some other marking device is used to mark the defective part of the electrode and attach a defect mark as a mark of the defective part. Therefore, if a defective mark is detected during the winding process, the defective part corresponding to the defective mark needs to be discharged as a bad electrode to prevent the d...
