Problems solved by technology

[0005] However, in the method of rotating the bobbin, there is a disadvantage that the next coil cannot be directly formed while the coil attached to the insertion tool remains in the state where the insertion tool is fixed.
However, the winding machines and the winding insertion machines described in JP-B-3691222, JP-A-2000-134876, and JP-2006-187132 tend to increase the introduction cost due to the complexity of the structure. A technology that requires a high degree of difficulty to improve reliability

Abstract

The invention provides a winding inserting machine which is provided with a plurality of coil racks for keeping coils; a winding machine possessing a coil rack rotary part for rotating the coil rack and utilizing the coil rack winding the coil rack rotary part to wind a plurality of metal lines to form coils; an inserting tool accepting the coil rack with the coil winding the coil rack; an inserting tool rotary part for rotating the inserting tool; and a coil rack work part for closing and separating the coil rack relative to the inserting tool. In addition, the coil rack and the coil winding the coil rack are successively accepted in the inserting tool.

Description

technical field [0001] The present invention relates to a wire insertion machine for inserting a coil formed by winding a metal wire into a stator. Background technique [0002] A general wire insertion machine is used to form a wire (coil) by winding an electric wire (metal wire) around a bobbin, and insert the formed coil into a predetermined position such as a slot of a stator of a motor. A coil used in a motor to which a large current is applied is formed by winding a plurality of metal wires side by side. In addition, in a stator used in a general motor, one-phase coils are assembled across a plurality of electrodes, but for the purpose of omitting the step of connecting the metal wires, it is preferable to wind a continuous metal wire over the plurality of electrodes. [0003] A method of forming a coil by rotating a flywheel around the bobbin in a state where the bobbin is fixed is known. In this case, the step of winding a continuous metal wire over a plurality of ...
