Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a multilayer multipole continuous coil configured such that flat coils of a pole pair window are automatically wound in sequence on a winding frame of a pole pair window. This relates to a winding device.

[Background of the invention]

The coils of each pole-pair window of a stator coil used in a flat motor etc. are formed as flat coils wound in alignment.

The entire stator coil is configured as a multi-layer, multi-pole continuous coil in which flat coils of each pole pair and window are arranged in a ring shape and the flat coils are electrically connected.

The conventional method has the disadvantage that the stator coil winding process cannot be fully automated.

This is because flat coils must be sequentially formed by a flyer on the winding frame of a plurality of pole pair windows arranged in an annular manner on the same plane.

In other words, since it is necessary to arrange multiple reeling frames at the same height, when forming a flat coil on a certain reeling frame, the rotational movement of the flyer may be obstructed by the reeling frame adjacent to that reeling frame. This is because it will be done.

Therefore, in the past, even if the winding of the flat coil of the pole pair window was automated, the connection with the adjacent flat coil, that is,
The reality is that crossover wire processing is done manually, which has the drawback of not being able to improve work efficiency.

[Purpose of the invention]

An object of the present invention is to provide a winding device for a multi-layer, multi-pole continuous coil that can automatically perform crossover wire processing. A feature is that the winding frames of the plurality of pole-pair windows arranged can be protruded in the direction of the flyer.

That is, after a certain winding frame is projected toward the flyer and a flat coil is formed on the winding frame by the flyer,
The winding process is carried out sequentially and continuously, such that the winding frame is moved back from the direction of the flyer together with the flat coil, and then the adjacent winding frame is made to protrude toward the flyer, and a flat coil is formed on the winding frame. It is composed of

[Embodiments of the invention]

The present invention will be explained below with reference to FIGS. 1 to 3.

First, the winding frame according to the present invention will be explained with reference to FIGS. 1a and 1b and 2 a and 2b.

FIG. 1a shows the plane of the winding frame.

As shown in the figure, the winding frames 1 to 8 of the pole pair windows are arranged on a rotating disk 11 in an annular shape.

Each of the winding frames 1 to 8 is placed on the rotating disk 11 so as to be able to protrude upward, although it is not possible to move on the surface of the rotating disk 11.

The grooves 10 to 16 formed in the winding frames 2 to 8, respectively, are
The crossover wire from the adjacent left side is positioned and accommodated inside it.

Further, the groove 9 provided in the winding frame 1 is for positioning and accommodating therein a portion near the tip of the wire rod fed out from the wire rod outlet 19 of the flyer.

In this embodiment, the direction in which the grooves 9 to 16 are formed on the winding frames 1 to 8 is as shown in the figure, but this is because the winding direction of the flat coil formed on a certain winding frame is the same as the winding direction of the adjacent winding frame. This is because it is opposite to the linear direction.

For example, if we take the example of winding frame 3.4, Fig. 1b (however,
As shown in the rotating disk 11 (not shown), the wire serving as a crossover wire from the not-illustrated winding frame (winding frame 2 in FIG. 1a) is connected to the winding frame 3 ( (not shown in a protruded state in the figure).

Then, the wire rod is wound around the winding frame 3 by rotating the flyer to the left when viewed from the top.

After this winding is completed, the flyer is stopped at a predetermined position and the winding frame 3 is lowered.

Then, the rotating disk (rotating disk 17 in FIG. 1a) is rotated by a predetermined amount.

Thereafter, the winding frame 4 is raised upward, and the flyer is rotated clockwise when viewed from above with the wire rod accommodated in the groove 12 of the winding frame 4.

In this way, the wire drawn from the winding frame 3 to the winding frame 4 can be connected to the groove 1 as a crossover wire between the coils wound on the winding frame 3 and the winding frame 4.
It is positioned and accommodated in 2.

Therefore, the crossover wire does not obstruct the rotation of the flyer.

When the winding on the winding frame 4 is completed, the flyer stops at a predetermined position to wind the wire on the winding frame (winding frame 5 in FIG. A fixed amount of rotation, a protruding rise of the winding frame 5, and a counterclockwise rotation of the flyer are sequentially performed.

FIGS. 2a and 2b show a situation in which winding on the winding frame 2 is started after winding on the winding frame 1 is completed.

As shown in the figure, after the formation of the flat coil 18 on the winding frame 1 is completed and the wire rod outlet 19 of the flyer is stopped at position A, the winding frame 1 is lowered and the rotary disk 17 is rotated by a predetermined amount. The frame 2 is 4O during the rotation of the wire rod outlet 19 of the flyer.
It will be located at the bottom.

After raising the winding frame 2 from this state, if the wire rod outlet 19 of the flyer is rotated clockwise, the wire from the flat coil 18 will pass through the flyer's wire rod outlet 19 sequentially through positions B and C. In the process, it is positioned and housed in the groove 10 as a crossover wire.

After that, the wire will be wound around the winding frame 2.

It should be noted that in FIG. 1, a suitable distance is provided between the winding frames, but this is not a serious problem.

FIG. 3 is a block diagram showing an example of an apparatus according to the present invention for automatically obtaining a winding frame for a multi-layer, multi-pole continuous coil.

The winding frames in this example (only the winding frame 1 is shown) are each rotary disk 1.
It is placed and housed in a recess 36 formed in 7 so as to be movable only in the vertical direction.

Here, in order to wind the winding frame 1, solenoid 3
The process starts by controlling the excitation state of the plunger 34 to cause the plunger 34 to protrude upward.

The plunger 34 operates the motor 24 with the reel 1 protruding upward (toward the flyer), and the flyer 20
drive the rotation.

Then, the wire rod fed out from the wire rod outlet 19 of the flyer 20 is wound around the winding frame 1 via the groove 9.

In this case, the amount of winding of the wire on the winding frame 1, that is, the number of turns of the coil formed on the winding frame 1 by 200 rotations of the flyer, is determined by the rotation pulses obtained from the rotary encoder 25 attached to the flyer 20, This can be determined by counting.

Therefore, the winding amount can be easily controlled by comparing the count value of the counter 26 and the set value of the winding position setter 28 using the comparator 27, and stopping the motor 24 when the respective values become equal. .

Therefore, when the comparator 27 outputs a signal indicating that the set value and the count value have become equal, the signal is used to reset the counter 26, and at the same time, the forward/reverse rotation control circuit 30 of the motor 24 is controlled, and once the motor is The rotation of 24 is stopped.

As a result, the rotation of the fryer 20 is also stopped, and the fryer 2
The wire rod outlet 19 of No. 0 is stopped at position A shown in FIG. 2a.

The output from the comparator 21 is also connected to a solenoid control circuit 31,
It is provided to the control circuit 32 of the motor 35 for driving the rotating disk 17.

Among these, the solenoid control circuit 31
is controlled to cause the plunger 34 to retreat once.

Further, the control circuit 32 operates to cause the motor 35 to rotate the rotary disk 1γ by a predetermined amount while the plunger 34 is being retracted.

When the rotating disk 11 rotates by a predetermined amount, the solenoid control circuit 31 controls the solenoid 33 to cause the plunger 34 to rise again.

Then, the winding frame 2 to be wound next comes to be located at the center of rotation of the wire rod outlet 19 of the flyer 200.

In this state, if the motor 24 is rotated in the opposite direction to the winding frame 1, the wire is wound around the winding frame 2 in the opposite direction to the winding frame 1.

Since the winding amount control for the winding frame 2 is the same as that for the winding frame 1, no further explanation is required.

By sequentially performing such control, flat coils are sequentially formed on winding frames 1 to 8''.

Note that reference numeral 29 is a power supply source O to the motor 24. [Effects of the Invention] As explained above, in the present invention, a plurality of winding frames arranged in an annular shape on a rotating disk are each individually moved in the direction of the flyer. The winding frame is made to be protrusive, and by appropriately controlling the rotation of the rotating disk, controlling the forward and reverse rotation of the flyer, and controlling the protrusion of the winding frame, flat coils are sequentially formed on each of the winding frames.

Therefore, according to the present invention, not only the winding of the coil but also the processing of the crossover wire can be automated, which has the effect of greatly improving work efficiency.
