Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stator coil winding device for a variable speed motor, such as a motor used in an electric washing machine or an electric fan, in which the rotational speed can be switched in stages. It is something.

Conventionally, as a device for winding a stator coil for a motor,
A winding device has been proposed in which the coils are wound around all of the winding frames, the number of which is opposite to the number of poles of the stator coil, and then the coils of each winding frame are simultaneously transferred to a coil insertion device.

That is, a single board is provided with a plurality of winding frames that are slidable in radial directions from the center thereof, and with each of the winding frames positioned in a direction away from the center of the board, the board is index-rotated to rotate each winding frame. By sequentially positioning the coil within the rotating circumference of the flyer, the coil is continuously wound around each winding frame without cutting the coil between poles. After the coils are wound around all the winding frames, each winding frame is positioned at the center of the board, and each winding frame is combined with the blade of the coil insertion device to reduce the winding frame and eliminate the tension in the coil.
The coil is dropped from the bobbin by its own weight or by other means between the blades of the coil insertion device. Such a device has the advantage of improving productivity.

However, since the winding device is dedicated to one type of motor, it cannot be adapted to high-mix, low-volume production. Furthermore, when transferring the coil from the winding frame to the coil insertion device, the coil falls freely, which disrupts the alignment of the coil, making it impossible to increase the space factor of the coil in the slot of the stator core. In addition, for example, the stator coil of a variable speed motor that switches the rotational speed in four stages is divided into four coils, ie, the first, second, third, and fourth coils, between the starting end and the ending end of the coil. Pull out and connect the terminal end and the starting end of the second coil, the terminal end of the second coil and the starting end of the third coil, and the terminal end of the third coil and the starting end of the fourth coil, and connect the first, second, and third coils. intermediate taps are formed, and a current is selectively applied between the starting end of the coil (starting end of the first coil) and each of the intermediate taps or the terminal end of the coil (the terminal end of the fourth coil) to drive the rotor. It is designed to rotate at the required speed.

When winding such a stator coil with the winding device, each time the first to fourth coils are wound, a starting end and a terminal end of each are pulled out, and a predetermined mark is attached to each lead wire, After winding is completed, a predetermined lead wire is connected to form an intermediate tap, and then the coil is transferred from the winding frame to the coil insertion device.

Therefore, winding of a coil such as a stator coil for a variable speed motor in which the intermediate tap is drawn out has the drawback of poor workability. The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to provide a highly versatile system that automatically pulls out the intermediate tap and enables transfer to a coil insertion device without disturbing the alignment of the coil. The present invention provides a stator coil winding device for a variable speed motor.

In order to achieve the above object, in the present invention, a turret head having a vertical rotation center and facing a flyer whose rotation center is horizontal is provided with a required number of turrets on a base. A winding means is provided in which a winding conveying jig in which a winding frame is arranged so as to be slidable in a radial direction is rotatably and detachably arranged, and a coil holder is index-rotated.
Each winding frame is sequentially positioned within the rotating circumference of the flyer, and a coil is wound around each winding frame, and the winding frame is positioned so as to face the wire stretched between the end of the coil wound around the winding frame and the flyer, and to move forward and backward. A tap wire processing means including a rotatably arranged gripping member is provided, and the gripping member is rotated while gripping the wire and pulling out the wire from the flyer, and the wire at the end of the coil and the wire pulled out from the flyer are rotated. are twisted together to form an intermediate tap, and after all the windings are completed, the tape applying means is arranged so as to face one of the winding frames of the coil holder at a position where the turret head has index rotated. , pull out the adhesive tape from the tape reel, affix the adhesive tape onto the coil wound on the winding frame, cut it to the required length, and insert it through the gap formed between the winding frame and the coil. After applying adhesive tape to the inner circumference of the coil to prevent the coil from being disturbed, the coil holder is removed from the turret head and the coil is held in the coil holder and transported to the coil insertion device. Features. An embodiment of the present invention will be described below with reference to the drawings.
