Abstract: Disclosed is a winder for an electrode assembly of a rechargeable battery for improving space usage. The winder includes a plurality of spools supplying a negative electrode member, a positive electrode member, a first separator member, and a second separator member, a mandrel stacking and spirally winding the first separator member, the negative electrode member, the second separator member, and the positive electrode member supplied by the spool, a first frame accommodating a predetermined number of spools from among the plurality of spools and the mandrel, a second frame connected to the first frame and accommodating other spools from among the plurality of spools, a reorienter installed between the first frame and the second frame and reorienting a progressing direction of one of the members, and a position controller controlling a position of the member that passes through the reorienter and progresses towards the mandrel.

Abstract: A filament winding apparatus includes a control unit, a rotation mechanism that rotates a mandrel, a hoop winding head that performs hoop-winding, and a helical winding head that performs helical-winding. The hoop winding head includes bobbins that feed fiber bundles to the mandrel and a circulation mechanism that circulates the bobbins around the mandrel. The control unit controls the rotation and circulation mechanisms such that the mandrel is rotated and the bobbins are circulated in the same direction during helical-winding. It is not necessary to cut fiber bundles after hoop-winding, and wasted fiber is not fed during helical-winding, thereby increasing economy and productivity.

Abstract: Provided are a winding method and a winding apparatus in which it makes possible to expedite the winding cycle with a relatively simple construction. In a winding method in which a plurality of conductor wires are arranged in parallel and wound around a reel to form a coil, which is dropped into a coil receiving jig, the plurality of conductor wires are temporarily wound around a bobbin, and the bobbin is attached to a flyer of a winding apparatus. The flyer is rotated to wind the plurality of conductor wires around the reel while drawing them out of the bobbin.

Abstract: The present invention aims at providing a method of wire winding without the failure of engagement of the wire caused by the deviation of position of a nozzle and bobbin terminal. The method is characterized in that, in the case of winding wire around the outer peripheries of rotating wind-up tools of which the peripheries are parallel to their axes of rotation, each wind-up tool 8 is attached to each of a plurality of spinning bodies 6 each of which has the rotation axis same as the wind-up tool, a rotation driving source is provided for each spinning body 6 for winding the wire, and the rotation driving sources are rotated in synchronism with each other.

Abstract: Methods and system for allowing the winder to continue to wind armatures and therefore avoid a total loss of production which would otherwise occur during the time which passes between breakage or overflow of the wire and intervention of the operator to restore normal winding conditions are provided. Upon detection of a wire breakage or overflow at a winding position, the wires from flyers corresponding to that position are withdrawn by a withdrawing device. In addition to withdrawing the wires from flyers corresponding to the position where the wire breakage or overflow took place, all flyer rotations in the multiple dynamo-electric part winder are stopped. The affected armatures are transferred to a reject track and new armatures to be wound are subsequently delivered to the winding positions. While the armature in the position where the breakage or overflow was detected remains unwound, the armature in the other position is wound and delivered to the conveyor.
