Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for winding an armature of a rotating electrical machine, and more particularly, the present invention relates to a winding device for winding an armature of a rotating electric machine, and more particularly, the present invention has an improved means for connecting a conductor to a commutator pawl. The present invention also relates to a winding device having improved means for cutting and terminal processing of a conductor, and for hooking the cut end of the conductor to a commutator pawl of the next armature.

In order to wind a wire on an armature having a core and a commutator, it is necessary to repeat the work of hooking the conductive wire to the commutator claw and the work of winding the same conductor around the core.

Further, when the winding of the conducting wire around the armature is completed, it is necessary to cut the conducting wire and perform the same operation to wind the conducting wire on the next armature.

In a conventional wire winding device, the work of hooking a conductor to a commutator claw involves first winding the conductor around a swinging hooker, then swinging the hooker at a predetermined commutator claw portion to hook the conductor to the commutator claw. This was done by dropping it into the commutator claw.

In addition, cutting after winding the conductor is done after clamping the conductor at the opposite side of the core from the commutator, and then cutting the conductor at the beginning of the conductor to the commutator claw of the armature that will be set next. The hooking was also done using the hooker mentioned above.

However, in such a conventional winding device, it is difficult to properly connect the conducting wire to the commutator pawl, and a problem may occur in which the conducting wire cannot be accurately hooked to the commutator pawl.

In addition, since the conductor is cut on the opposite side of the commutator as described above, the cut portion to the part hooked to the commutator claw remains as an extra line, resulting in wasted material and the extra line. Cumbersome manual labor was required for excision.

SUMMARY OF THE INVENTION Therefore, the present invention solves these conventional drawbacks and provides a winding device that enables good connection between conductor wires and commutator claws, and also allows winding around an armature without producing extra wires. It is intended for this purpose.

An embodiment of the present invention shown in the drawings will be described below.

FIG. 1 shows an example of an armature for a rotating electric machine, which is wound by the apparatus of the present invention.

As shown in the figure, this armature 1 has a shaft 2, a core 3 press-fitted to the shaft 2, and a commutator 4 adjacent to the core 3 and press-fitted to the shaft 2. It has a winding 5 wound around a commutator 4.

The core 3 has many slots 3a, and the commutator 4 has many claws 4a at the end on the core side.

The winding 5 is constructed by winding a conducting wire 5a around the core 3 and commutator 4 as follows.

That is, after hooking the tip 5a' of the conducting wire 5a to one claw 4a of the commutator 4, the conducting wire 5a is connected to the two throwers) 3a.
The conductor 5a is then wound around the core 3 a predetermined number of times through the slot, and then the conductor 5a is hooked onto the next claw of the commutator 4, and then the conductor 5a is wound around the core 3 through the next two slots, and this is repeated thereafter.
Finally, the winding 5 is applied by hooking the conductor end 5a'' to the same commutator claw as the hook on which the lead end (winding start end) 5a' is hooked.

FIG. 2 shows a winding device according to an embodiment of the present invention for applying winding 5 to armature 1. As shown in FIG.

This winding device is configured to wind the conductor while directly hooking the conductor onto the commutator tabs, and is capable of winding the armatures that are set in sequence in a fully automatic manner without leaving excess conductor wire. Generally speaking, winding is performed by the following procedure.

In other words, if we explain the process from the start of winding the conductor on one armature to the start of winding the conductor on the next armature, we will explain the winding of the conductor on the held armature and the winding of the conductor after winding. Clamping, cutting and terminal processing of the conductor after clamping (completion of winding), removing the armature after winding is completed, setting the next armature, attaching the above clamped armature to the commutator claw of the set armature The winding device repeats the steps of hooking the tip of the conductor (winding start end), then winding the conductor around the armature, and winding the armature that is set in sequence.

For this reason, the above-mentioned winding device has a holding means A1 for holding the armature 1, a winding means B1 for winding the conductor around the held armature 1, a winding means B1 for winding the conductor around the held armature 1, a winding means for directly hooking the conductor to the commutator pawl when winding the conductor. guiding means C for guiding the conductor; clamping means D for clamping the conductor after winding the conductor around one armature; and clamping means D1 for clamping the conductor after winding the conductor around one armature. Conductor cutting/terminal processing means E1 for completing the winding of the wire; Setting means F for removing the armature on which winding has been completed and setting a new armature;
1 and one of the commutator claws of the set armature is provided with winding start end processing means G for hooking the leading end of the conductor in cooperation with the clamp means.

The details of each of the above means will be explained below.

(1) Holding means A Holding means A includes a chuck 10 that grips one end of the armature shaft 2 on the commutator side, and uses this chuck 10 to hold the armature 1 set by the setting means F.

The chuck 10 has a male tapered surface 101 on its outer periphery, and grips and releases the armature shaft 2 in response to the operation of a member having a matching female tapered surface.

The winding start end shaping arrow 90 forming the winding start end processing means G is used as the member with the tapered surface of the function described above, and the chuck 10 moves the conductor wire to the armature 1 by vertical movement of this shaping arrow, which will be described later. The armature 1 is held during winding and cutting and terminal processing of the conductor, and is then released from holding.

The chuck 10 is connected to an index shaft 11 at its lower end, and is driven by a drive source (not shown) to rotate intermittently along with the index shaft 11 by a predetermined angle in a fixed rotation direction.

(2) Winding means B The winding means B includes a hollow first rotating shaft 20, a hollow second rotating shaft 21 fixed to the tip of the first rotating shaft 20 by an appropriate method such as a bolt, It has a former support shaft 22 supported by this second rotating shaft 21, and a former 23 fixed to its tip by an appropriate method such as a bolt.

The first rotating shaft 20 is mounted on a box 24 with a bearing 25°2.
It is rotatably supported by 6.26'.

A pulley 27 is coupled to the rear end of the first rotating shaft 20, and the first rotating shaft 20 is connected to a forward/reverse rotation drive device (not shown) via the pulley 27.

As a result, the first rotation shaft 20 and the second rotation shaft 21 fixed thereto repeat normal rotation, stop, reverse rotation, stop, and normal rotation.

A knock ring 28 is fixed to the first rotating shaft 20 inside the box 24, and a knock 29 that engages with the knock ring 28 is attached to the box 24 together with a cylinder 30 that drives the knock ring.

These knock rings 28 and knocks 29 are the first and second knock rings.
The rotating shafts 20 and 21 of the rotary shafts 20 and 21 are stopped at predetermined positions.

Two gear support parts 211 and 211' are formed on the second rotating shaft 21 and are parallel to each other.
1 is supported so as to be rotatable and immovable in the axial direction.

First and second gears 32 and 32' of the module having the same number of teeth are connected to both ends of the support shaft 31, one of which is connected to the first fixed gear 2 provided on the former support shaft 22.
21, and the other gear meshes with a second fixed gear 33 fixed to the box 24 with bolts or the like.

The former support shaft 22 is supported with respect to the second rotating shaft 21 by bearings 34, 34'.

Therefore, even if the first and second rotating shafts 20.degree. 21 rotate, the former support shaft 22 and the former support shaft 22 and The fixed former 23 remains stationary.

The former 23 provides a guide for sliding the conductor into the slot of the armature core 3 and is located along the armature 1.

The winding means B further includes a flyer arm 35.

The flyer arm 35 is attached at its rear end to an arm attachment portion 212 provided on the second rotating shaft 21, and is parallel to the axes of the first and second rotating shafts 20 and 21.

The flyer arm 35 swings on the side of the armature 1 by the rotation of the first and second rotating shafts 20°21.

The flyer arm 35 has two guide nozzles 36 and 37 for guiding the conductor.

As shown in the figure, the conducting wire 5a wound around the armature 1 passes through the inside of the first rotating shaft 20, is guided by a rotatable roller 38 supported inside the tip of the first rotating shaft 20, and is further Through the guide nozzles 36 and 37 of the flyer arm 35,
Guided to armature 1.

Conductor 5a to armature 1 held by the holding step A
When winding, the first and second rotating shafts 20, 21 are rotated in the forward direction a predetermined number of times by being driven by a forward/reverse rotation drive device (not shown).

In response to this, the flyer arm 35 swings around the side of the armature 1 in the same direction a predetermined number of times.

Then, the conductor 5a whose tip is hooked to one of the commutator claws of the armature 1 (this process is performed by the winding start end processing means G)
While being pulled out from the tip guide nozzle 37 of the flyer arm 35, it rotates together with the nozzle 37, and the former 23
The wire is guided around the armature core 3 by a predetermined number of times and is wound around the armature core 3 a predetermined number of times.

This is the first winding of the conducting wire around the core 3.

When this first winding is completed, the first and second rotating shafts 20.
21 and the flyer arm 35 at a position where the conducting wire 5a drawn out from the tip nozzle 37 reaches the commutator claw,
Stop once.

A knock ring 28 and a knock 29 are used for stopping at this predetermined position.

Then, the rotating shaft 20°21 and the flyer arm 35
rotates at a predetermined angle in the reverse direction and stops.

During this time, the conducting wire 5a is hooked onto the commutator claw, which will be described later.

Thereafter, the flyer arm 35 turns in the forward rotation direction a predetermined number of times together with the rotating shaft 20.21, and since the armature 1 has already rotated by a predetermined amount, the conductor is wound around the core 3 through the next two slots. (second wrapping).

Thereafter, the above-described operation is repeated to wind the conducting wire 5a around the armature 1.

(3) Guide means C The guide means C includes a cylindrical hooker 40.

This hook 40 surrounds the holding means A, and its upper end is located around the commutator 4 of the armature 1.

As shown in FIGS. 3 to 7, at the upper end of the hooker 40 located around the commutator 4, there is particularly a commutator claw 4.
A claw portion 401 located around a, and a guide arrow 402 that protrudes inward from this claw portion 401 and enters the lower side of the commutator claw 4a.
, and a slope 403 that forms a gap between the tip of the claw portion 401 and the tip of the claw portion 401 .

In the illustrated example, the claw portion 401, the guide arrow 402 and the slope 4
03 are provided in two pairs, but in this case, by providing two sets of the winding means B, two conductive wires can be wound around one armature, and the winding time can be shortened.

However, here we will explain the case where one set of winding means B is provided, so the claw portion 401, the guide arrow 402 and the slope 40
One pair of 3 is sufficient.

The hooker 40 is connected at its lower end to a hollow shaft 41 by an appropriate method such as a bolt or by a knock pin 42, and is driven by a drive source (not shown) via this, thereby reciprocatingly rotates by a predetermined angle.

Therefore, the hooker 40 operates every time the winding means B finishes winding the conducting wire 5a on the armature core 3 for the first time, second time, etc. In conjunction with the pivoting movement of the flyer arm 35 and the rotation of the armature 1 through a predetermined angle by the holding means A, the conductor 5a is moved between the commutator claws 4
Hook a directly.

That is, when the flyer arm (tip guide nozzle 37) stops after winding any one of the conductive wires around the armature core 3, the hooker 40 rotates by a predetermined angle in the direction of arrow A in FIG.

At the same time, the armature 1 is rotated by the holding means A, so that the hook 40 is
The guide arrow 402 of the hooker 40 is rotated by a predetermined angle in the direction of the same arrow as shown in FIGS.

Then, the flyer arm (tip guide nozzle 37) of the winding means B rotates in the opposite direction to the direction of rotation when winding the armature core, that is, in the direction of arrow C in FIGS. 3 to 5, and stops. do.

As a result, the conductor 5a changes from a solid line state to that shown in FIGS. 3 and 4.
It transitions to the state indicated by the two-dot chain line in the figure, and at that time is guided by the guide arrow 402 and hooked on the commutator claw 4a.

Thereafter, the hooker 40 rotates in the opposite direction to that in the above case and returns to its original position, and the slope 40 is rotated as shown in FIGS. 6 and 7.
3 comes to rest at a position corresponding to the hook 4a on which the conducting wire is to be hooked.

Then, the flyer arm of the winding means B is shown in FIGS. 3 to 5.
It turns in the two directions of arrows opposite to those shown in the figure (directions when winding around the armature core), and the conducting wire 5a follows this.

At this time, the conducting wire 5a slides on the slope 403 of the hooker 40, as shown by the two-dot chain line in FIG. state.

In this way, the work of hooking the conducting wire 5a to one commutator pawl 4a is completed.

By the above-mentioned winding means B and guiding means C, the armature 1
The conductor 5a is wound around the armature core 3 and commutator claw 4a.
It is wound by repeating the hooking and hooking.

Then, when the conductor wire is hooked to each commutator claw 4a once again and the conductor wire 5a is hooked again to the claw where the start end of the conductor winding was hooked, as shown in FIG. finish.

(4) Clamping means D The clamping means D has a wire clamper 50 for clamping the conducting wire.

Although not shown in detail, this clamper 50 is composed of two arms, and is driven by a cylinder 51 to clamp the conducting wire 5a between the two arms.

The drive cylinder 51 to which the clamper 50 is attached is swingably supported by a ring-shaped member 52 by a support pin 53 at its lower end, and is connected to a slide ring 55 by a lifting pin 54.

The slide ring 55 is fixed to a cylindrical body 56 that is slidably fitted to the hollow shaft 41, and the ring-shaped member 52 is slid onto the cylindrical body 56 while being raised by a predetermined distance with respect to the slide ring 55. possible to be mated.

A compression coil spring 57 is disposed between the ring-shaped member 52 and the slide ring 55, and the ring-shaped member 52 is elastically supported by the slide ring 55.

The slide ring 55 is moved up and down in two stages by a drive device (not shown).

That is, the illustrated position is the lowest position, and the slide ring 55 performs the first upward movement from this position.

The ring-shaped member 52 also follows this, and the clamper 50 and cylinder 51 also rise together.

When this first rise is completed, the ring-shaped member 52 is just
It comes to a position where it hits the stopper 58.

When the slide ring 55 rises to the second stage, the ring-shaped member 52 is prevented from rising by the stopper 58, so only the slide ring 55 rises while contracting the coil spring 57.

As a result, the clamper 50 and the cylinder 51 are driven by the lifting pin 54 and swing about the support pin 53 as a fulcrum.

The operation in case of a downward movement is opposite to that described above.

When the winding means B finishes winding the conducting wire 5a around one armature 1, the slide ring 55 performs the first upward movement.

Although the position of the clamper 50 is shifted in the figure for ease of explanation, when the slide ring 55 rises to the first stage, the clamper 50 moves from the commutator pawl of the armature 1 to the tip guide nozzle 37 of the flyer arm 35. It comes to a position where it can hold the conductive wire 5a leading to.

Then, by driving the cylinder 51, the clamper 50 clamps the conductive wire 5a and stops in this clamped state.

The slide ring 55 rises to the second stage after the conductor wire is cut and the terminal is processed, which will be described later.

(5) Conductor cutting/terminal processing means E This means E, as shown in FIGS. 9 to 11,
A commutator claw bending arrow 60 is held movably in the former 23 so as to face the commutator claw, and this bending arrow 6
It has a cutting blade 61 held inside the 0 so that it can move forward and backward.

The bent arrow 60 has its tip connected to two adjacent commutator claws 4 of the armature 1.
The structure is such that the drive pin 62 can be bent at the rear end.
The drive pin 62 is connected to the drive pin 62 by screwing into the tip of the drive pin 62 .

The bending arrow 6G is loaded by a compression coil spring 64 guided by a guide 63 to a retracted position where it only slightly protrudes from the former 23 (FIGS. 9 and 10).

The cutting blade 61 has a long hole 611 through which a pin 65 fixed to the bending arrow 60 is inserted, and the interference between the pin 65 and the long hole 611 allows it to slide relative to the bending arrow 60 by a certain amount. It is.

A cushion rubber 66 is disposed between the rear end of the cutting blade 61 and the tip of the drive pin 62, so that the cutting blade 61 is maintained at a position advanced relative to the bending arrow 60.

The cushion rubber 66 allows the cutting blade 61 to retreat and prevents damage caused by overload.

A flange 621 is provided at the rear end of the drive pin 62, and a bushing 67 engages with this flange 621.

The bushing 67 is held by the second rotary shaft 21 so as to be movable forward and backward, and is normally loaded by a coil spring 68 to the retracted position.

This bushing 67 is provided with an engaging portion 671 at its tip that engages with the flange 621 of the drive pin 62, and a hook portion 672 at its rear end.

A hook-shaped attachment 70 provided at one end of the lever 69 engages with the hook portion 672 of the button 67.

The lever 69 is rotatably supported by the box 24 with a pin 71, and is connected to a cylinder 72 at the other end.

When the cylinder 72 is driven, the lever 69 is rotated counterclockwise in FIG. 2 using the pin 71 as a fulcrum, thereby advancing the bushing 67 and the driving pin 62, and thus the bending arrow 60 and the cutting blade 61.

Note that the bushing 67 is held by the second rotary shaft 21 that rotates, but when the cylinder 72 is activated, it stops at the position shown in FIG. The attachments 70 are respectively engaged.

For this reason, a part of the bushing 67 is made into a polygon, for example,
By making the hole of the second rotating shaft 21 in which it is held also polygonal, it is prevented from rotating with respect to the second rotating shaft 21, and the engaging portion 671 is perpendicular to the paper surface in FIG. The structure is open at both ends.

The conductive wire cutting/terminal processing means E configured in this way has 1
After the winding of the conductor wires around the two armatures 1 is completed and the conductor wires 5a are clamped by the clamping means, the operation is started.

Prior to this, the hooker 40 is rotated and stopped at a position where it does not interfere with the advancement of the arrow 60 and the cutting blade 61.

Thus, the bending arrow 60 and the cutting blade 61 are moved by the cylinder 72 to the lever 69, the bushing 67, and the armature 1 and the clamped conducting wire 5a shown in FIGS. It is driven via the drive pin 62 and moves forward toward the commutator claw 4a to which the conducting wire 5a is hooked and the claw 4a adjacent thereto.

Then, as shown in FIG. 11, the two commutator claws 4a are bent by a bending arrow 60.

4a is temporarily bent to prevent the conducting wire 5a from separating from the claw 4a, and then the cutting blade 61 cuts the conducting wire 5a in the immediate vicinity of the claw 4a.

If an overload is applied to the cutting blade 61 here, the cutting blade 61 is elastically supported by the cushion rubber 66, so
The cutting blade 61 stops advancing and is protected.

After the above operations are completed, the bending arrow 60 and the cutting blade 61 retreat and return to their original positions, thereby completing the winding of one commutator 1.

The state of the conducting wire 5a for each commutator pawl 4a in the armature 1 whose winding has been completed is as shown in FIG. 12, and the armature 1 having the winding 5 shown in FIG. 1 is obtained.

(6) Setting means F The setting means F has a collet chuck 80 and a holder 81 paired therewith.

The collet chuck 80 is driven by a cylinder 82,
The armature 1 is connected to the holder 81 by the wedge principle due to its tapered surface.
grip the other end of the shaft 2.

These collet chuck 80, holder 81, and cylinder 82 are held by a table 83 that moves up and down and rotates intermittently in a fixed direction.

When the winding 5 on the armature 1 is completed as described above, the collet chuck 80 is driven by the cylinder 82 to hold the armature 1.

Chuck 1 of holding means A that used to hold armature 1
0 releases the holding of the armature 1 by raising the shaping arrow 90.

Then, the table 83 rises and rotates by a certain angle,
The armature 1 with the winding 5 completed is taken out, and a new armature held by another collet chuck is set further down.

After setting the new armature on the collet chuck,
The armature is held until the winding means B completes the first winding of the conductor around the armature core, after which the holding is released and the function is transferred to the holding means A.

') Winding start edge processing means G This means G includes a winding start edge shaping arrow 90 which also serves the function of controlling the operation of the holding means A as described above.

This shaped arrow 90 has a cylindrical shape, and has a chuck 10 and a hooker 40.
and as shown in FIGS. 13 to 16,
The upper end has a slope 901 that can enter between the commutator claw 4a and the commutator body and has an inclination along the commutator claw.

It also has a protrusion 902 provided at one end of the slope 901.

Furthermore, the shaping arrow 90 is a male tapered surface 101 of the chuck 10.
It has a female tapered surface 903 that matches.

The shaping arrow 90 is connected to a hollow shaft 91, and is moved up and down and rotated in a fixed direction by a drive device (not shown).

As mentioned above, when the winding on one armature is completed, the shaping arrow 90 rises to release the armature from being held by the chuck 10, and then a new armature 1 is set by the setting means F. .

The state in which this new armature 1 is set is as shown in FIG.

From this state, the slide ring 55 of the clamping means performs a second upward movement.

Then, the clamper 50 swings in the direction of the arrow H, and sends the clamped tip 5a' of the conductive wire 5a between one commutator claw 4a and the commutator body, as shown in FIG.

Then, the shaping arrow 90 further rises, and the sloped part 90 at the upper end
1 enters between the claw 4a and the commutator body.

Then, as shown in FIG. 15, the leading end 5a' of the conductive wire is bent and wrapped around the claw 4a by the protrusion 902.

In this state, the hooker 40 was kept in a position where it did not interfere with the shaping arrow 60 during the previous cutting and terminal processing of the conductor to the armature.
returns to its original position as shown in Figures 6 and 7, and then
Winding of the conducting wire 5a by the winding means B is started.

FIG. 16 shows the state immediately after the winding of the conducting wire 5a hooked onto the commutator claw 4a by the shaping arrow 90 has started.

When the first winding on the armature by the winding means B is completed, the shaping arrow 90 descends, and the clamper 50 releases the clamp on the conducting wire 5a and descends.

To summarize the operation of the winding device equipped with each of the above-mentioned means A to G in order from the setting of the armature, first, the armature 1 is set by the setting means F, and this setting means F
With respect to the armature 1 held by the collet chuck 80, the leading end 5a' of the conducting wire 5a is hooked onto the first commutator claw 4a by the clamping means and winding start end processing means G.

Then, the winding means B performs the first winding of the conducting wire 5a around the armature core 3.

Thereafter, the clamping means and winding start end processing means G are lowered, the armature 1 is held by the holding means A, and the setting means F releases the holding of the armature 1.

Next, mainly due to the operation of the guide means C, coupled with the operation of the winding means B and the operation of the holding means A, the conducting wire 5a is directly hooked to the second commutator claw, and then the winding means B carries out the second winding. Winding of the conducting wire 5a is performed.

After that, with the same operation, hook the conductor to the third commutator claw,
The third winding process is repeated, and the conducting wire is hooked onto the first commutator claw 4a, thereby completing the winding of the conducting wire around the armature 1.

Subsequently, the conducting wire 5 is clamped by the clamping means, the first commutator claw and the commutator claw adjacent thereto are temporarily bent by the conducting wire cutting/terminal processing means E, and the first commutator claw is temporarily bent. The conductive wire 5a is cut near the claw.

This completes the winding of one armature 1.

When the winding is completed in this way, the conductor cutting/terminal processing means E
returns to its original position, and the armature 1 is held by the setting means F.

Then, the holding means A releases the holding of the armature 1, and the setting means F operates to remove the armature 1 and set a new armature.

Thus, according to the above winding device, the conducting wire is wound around the armature while being directly hooked onto the commutator claws, so that good results can be obtained between the conducting wire and each commutator claw.

Furthermore, since a guide means having a relatively simple structure is used for this purpose, the mechanism can be significantly simplified.

In addition, after the conductor is wound around the armature, it is cut near the commutator pawl, and the tip of the cut conductor is hooked onto the commutator pawl of the next armature, so there is no extra wire on the conductor. , windings are applied to the armatures that are set in sequence.

Therefore, work such as cutting extra lines is not necessary, and materials can be saved.

As described above, according to the present invention, a good connection between the conducting wire and the commutator claw can be realized with a simple mechanism, and a highly reliable armature can be obtained.

In addition, winding can be performed without creating extra wires, making it possible to save materials and reduce man-hours.

Furthermore, highly reliable windings as described above can be applied to the armatures that are set one after another in a fully automatic manner without producing extra wires.
