Abstract

PURPOSE:To have a high-speed, high-prcision control of an actuator (wire guide) working in a flyer rotary system of a flyer type winding machine, with a small- sized arrangement, by controlling the actuator through a drive shaft inserted in a hollow, rotary spindle. CONSTITUTION:In an arrangement in which a wire 6 is wound round an armature core 7 through the action of a rotating flyer 1, the flyer 1 is fixed to the periphery of the tip of hollow, rotary spindle 2. Drive shafts 16, 17 in double construction are slidably fitted to the hollow of said spindle 2, and the slide given by cylinders 21, 22 on the shafts 16, 17 puts actuators 15, 15' in operation as a wire guide with the aid of facial plates 23', 24' and levers 27, 27'. In order to make location of these actuators 15, 15', stoppers 30, 30' are installed, which are driven by pulse motors 28, 28' and rotate lead screws 29, 29' so as to specify the advancing or retracting position, whereby the facial plates 23, 24, i.e. actuators 15, 15', are located in their respective places.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of positioning and driving an actuator within a flyer rotation system of a flyer winding system in which wires are wired directly or indirectly to the iron core of an electric motor at high speeds and high speeds. I am very proud of what I have done.

Conventionally, for winding the iron core of an electric motor, for example, a second winding machine is used as a winding machine for winding the coil around the armature core, as shown in Fig. 1.
The flyer winding machine shown in the figure is used. That is,
At one end of the main shaft 2 with the flyer 1fc fixed in a predetermined position,
A wire 6 is wound around an AM guide 5 which is attached to a chuck 4 via a bearing 3, and is inserted into a slot 8 formed on the outer circumferential surface of an armature core 7. be.

In such a winding method using a flyer, the wire 6 is
In order to guide the wire from the wire supply source 9 to the tip of the flyer 1, the wire 6 must be placed inside the rotating king 11112, and a hollow rotating main shaft is generally used. This is something that anyone in the industry who does flyer winding can understand.

For this reason, the supports of the chuck 4 and the line guide 5 are suspended (referred to as a floating island mechanism by those in the art) within the n1 fryer rotating system with support attached to the rotating main shaft 2 via the bearings 3.

Therefore, it is difficult to completely incorporate the actuators for driving the chuck 4, the wire guide 5, the winding frame, etc. into the flyer rotation system because the wiring and piping become tangled each time the flyer rotates.

In addition, as a device for driving the support member in the flyer rotation system, there are
16, etc., but all of them require large drive motors, cylinders, etc. to drive the entire device support, and are slow in operation, making it difficult to drive for highly accurate positioning.

There is no method or device for positioning the actuator of the support (for example, line guide, former, chuck, etc.) in a flyer rotation system in a small size, at high speed, and with high sieving degree, and fi!
, it was not possible to make accurate windings.

The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a method and apparatus for positioning and driving supports in a flyer rotation system at high speed and with high precision.

That is, in the present invention, in order to achieve the above object, a mechanism for controlling the actuator (line guide or former) of the support section in the fryer that rotates at high speed is provided on the outside of the 2-band unit, and the flyer is rotated. The control mechanism provided on the outside of No. 111, which engages with the drive shafts multiplexed in the main shaft, uses a pulse motor to move the position of the surface, and the stopper engaged with the screw. Operate and set it at the desired position, drive it with a cylinder and press it against the stopper. The position i is determined by if+M degrees.

Furthermore, by separating the drive unit and positioning unit,
It is characterized by increased speed of operation and miniaturization of the motor.

Hereinafter, nine examples of the present invention will be explained with reference to the drawings.

FIG. 3 shows an embodiment of the present invention, in which a conventional flyer type armature winding machine is generally shown.
'A coil of wire is wound around the slotted core of a generator, generator, or other similar machine.

Generally, 1 is a flyer, and the wire 6 is wound around the armature core 7 by the rotation of the flyer 1.

This flyer 1 is fixed to the outer peripheral tip of a hollow shaft, that is, a rotating main shaft 2, and a pulley 10 is attached to the outer end of the main shaft 2.
is connected to the main shaft 2, and a belt 11 for transmitting power to the pulley 10 is connected to a drive motor (not shown) for rotating the fryer at the bottom of the horizontal table 12. The main shaft 2 is supported by a bearing 13 and fixed to a winding head 14.

In order to drive the actuator (line guide or former) 15 at high speed and with high precision in the limited space inside the flyer 1 which rotates at high speed, the present invention has a dual drive shaft in the hollow of the main shaft 2. 16.17 is main shaft 2 and key 18
They are connected together with a long hole in the sliding direction, allowing them to slide freely.

The drive shaft 17 has a clear path for the wire 6, and the wire 6 is sent from the wire supply section 9 to the seven layer 1. Both ends of this drive shaft 16,170 are each held by bearings 19,20 and are moved by cylinders 21,22. The power of the cylinder 21.22 is jointed to the face plate 23.24, and the cylinder 21.22 moves together with the face plate 23.24, and the cylinder 21.22 moves in unison with the face plate 23.24, and the drive shaft 16.
17, and furthermore, a bearing 25' in the flyer rotation.
, 26′? Through this, levers 27, 27' engage the face plates 23', 24' and the actuators 15, 15'.

The actuator 15.15' is positioned using a pulse motor 28.28' and a lead screw 29.29.
', and a lead nut stopper 30.30' is attached. A detent guide 31.31' of the stopper 30.30' is attached.

Also, a detection dog 32.32' is attached to the stopper 30.30'.
There is a sensor 33.33' and an actuator 15.
The origin of 15' is taken by the pulse motor 28, 28'.

Based on the above configuration, the positioning drive of the actuators 15, 15' is performed by taking the initial origin of the actuator using the pulse motor 28, 28' and the sensor 33, 33', rotating the lead screw from the origin with the pulse motor, and rotating the stopper. Move to the desired position, stop the rotation of the pulse motor, and use the cylinder to move the face plate 23, 24 to the stopper 30.
Press it against 30'. Thereby, power is transmitted from the connected lever to the actuator 15.15' via the drive shaft, and the position is determined by the stopper. When the actuator moves backward, the cylinder moves backward.

In this way, while controlling the motor and cylinder, the actuator within the flyer rotation is controlled according to the control program of the device.

As described above, according to the present invention, - In order to drive the actuator in the flyer rotation system, a drive shaft is passed through the rotating main shaft, and a motor and a cylinder are engaged with the drive shaft on the wire supply source side. By controlling the actuator using the actuator, it is now possible to control the actuator with high speed and high precision in a compact size. In particular, for the winding of the armature core, the wire guide or former can be retracted when indexing the armature core, and can also be flexibly changed before movement according to the winding coil specifications, improving efficiency. Winding became possible.
