TAPE WINDER
20220242690 · 2022-08-04 ·

A roll tape 1 is held by a tip end portion of an arm 3 connected by a pivot shaft 4 fixed to a rotating body 5, and an enlarged diameter curved surface portion 6 is provided that comes into contact with the arm 3 that pivots at a time of rotation. In an angle range in which the arm 3 is in contact with the enlarged diameter curved surface portion 6, the arm 3 is pushed in a rotation outward direction at the time of rotation such that the tape stretched from the roll tape 1 to an object 9 is wound around the object 9 while being pulled out. In an angle range in which the arm 3 is not in contact with the enlarged diameter curved surface portion 6, the tape previously pulled out from the roll tape 1 is wound around the object 9 while being wound up on the object 9. By repeating this alternately, displacement of the object from the rotation axis is suppressed, and proper winding is performed.

WIRE TENSION CONTROL DEVICE AND BRAIDING MACHINE USING THE SAME

A wire tension control device including a bobbin and a magnetic moment generator is provided. The bobbin is configured to provide a wire. The magnetic moment generator includes a stator and a rotor relatively rotatable with respect to the stator. The rotor is connected to the bobbin. When the bobbin drives the rotor to rotate, the magnetic moment generator generates a tension on the wire.

Winding apparatus and coil component manufacturing method
10832865 · 2020-11-10 · ·

A winding apparatus for a coil component in which wires are wound around a core. The winding apparatus includes a wire position support including wire route holes in which the wires are inserted, a wire feeder that feeds the wires to the wire position support such that tension is applied to the wires, a winding driver that orbitally revolves the wire position support around the core such that the wires are wound around the core while twisted, a rotator that rotates the core, and a controller that controls the winding driver and the rotator. The controller controls a rotation direction of the core with regard to an orbital revolution direction of the wire position support and an orbital revolution speed of the wire position support to prevent generation of a kink of a wire between a wire feeder and the wire position support.

FILAMENT WINDING DEVICE AND BOBBIN REPLACEMENT METHOD

A filament winding device includes: a helical winder which winds a fiber bundle around a liner; a bobbin supporting shaft which rotatably supports a bobbin for providing the fiber bundle to the helical winder and a bobbin different from the bobbin in a state in which winding-initiation ends of the fiber bundle wound around the bobbin and winding-termination ends of the fiber bundle wound around the bobbin connect to each other; and a fiber bundle storage unit. The fiber bundle storage unit has a stopper which can switch the fiber bundle storage unit between a storage state in which the fiber bundle is stored in the fiber bundle storage unit and a storage-released state in which the fiber bundle has been released from storage in the fiber bundle storage unit and the fiber bundle is supplied from the fiber bundle storage unit to the helical winding unit.
