Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a flat motor armature manufacturing apparatus, and more particularly to a flat motor armature manufacturing apparatus equipped with an automatic connection mechanism between a commutator and a coil tap.

[Background of the invention]

Conventionally, coil winding work for this type of armature has relied exclusively on manual labor, which takes a lot of time.

U.S. Pat. No. 3,550,645 proposes a method and apparatus for winding a star-shaped coil, but it is not satisfactory in terms of speed. Therefore, the present inventor previously proposed a device for continuous automatic winding at high speed using a rotating plate having a group of pins and a winding jig (Japanese Patent Laid-Open No. 58-29352).
(see issue). In this proposal, the coil tap, which serves as the coil lead, is only twisted and does not automatically connect to the commutator.

[Purpose of the invention]

The present invention aims to provide an unmanned and highly efficient armature manufacturing device by automatically winding a required number of coils at high speed and also by automating the connection of commutator pieces and coil taps. be.

[Summary of the invention]

The present invention has a large number of pins installed at a predetermined pitch on at least double concentric circles. A rotary plate that is index-rotated, and a first volume jig and a second volume jig that are arranged with a gap G in order to wind electromagnetic wires around specific pins among these pins.

Said 1st. Volume 2 Jig Empty! A mechanism for winding the electromagnetic wire with a single coil around the plurality of pins through the iiG to perform high-speed winding of the coil, and a mechanism for automatically connecting the coil tap drawn out from the coil to the commutator piece. The aim is to achieve continuous high-speed automation of winding work and connection work between coil taps and commutators.

[Embodiments of the invention]

The configuration of the present invention will be explained in more detail below based on the drawings of one embodiment. 1 is a pedestal that supports the entire device; this pedestal 1
A column 2 is provided in the center of the column. A turntable 3 is rotatably supported on the support 2. A gear 4 is integrally provided on the turntable 3, and an output gear fixed to the output shaft of a gear motor 5 is meshed with the gear 4. A guide pin 6 is biased by a fluid or gas cylinder to position and hold the turntable 3 at a predetermined position. An index table 60 is rotatably supported on the turntable 3 by a thrust bearing 61, and an index gear 7 is fixed to the lower part of the index table 60. Reference numeral 8 denotes a rotary plate fixed to the upper surface of the index table 60, which rotates the index together with the index table 6o. This rotating plate 8
A hole 8-1 is formed in the center of the coil tap for pulling out the coil tap connected to the commutator downward. For this reason, the one-rotation plate 8 has a donut shape.

8-2 is an insulating film interposed between the lower surface of the rotary plate 8 and the index table 60 for electrical insulation.

Reference numeral 8-3 is a ceramic or fluorine resin coating provided on the outer periphery of the rotating plate 8 for the same purpose, and 60-5 is an insulating stand made of Bakelite that supports clamps 62 and 69, which will be described later.

A gear 9 meshes with the index gear 7, and this gear 9 is driven by a stepping motor 10. The gear 9 and the index gear 7 are engaged with each other intermittently by a lever 11 operated by an air cylinder 12.

The rotation angle of the index table is controlled by counting the number of slits provided on the outer periphery of an angle detection plate 9-1 that rotates together with the gear 9 using, for example, an optical or magnetic sensor 9-2.

Although this example shows an example in which a detection plate is attached to the gear 9, a detection idle gear may be attached and an angle detection plate may be attached to that gear.

The gear to which the angle detection plate is attached is set to make one rotation of the index gear 7ON, and the gear is attached as many times as the number of divisions of the detection plate's Surin L-winding wire assembly jig. Even if the product specifications change, that is, the number of divisions changes, a predetermined division angle can be easily obtained by simply changing the slits 9-3fi' of the angle detection plate. That is, the rotation angle for one division can be obtained by counting the slits N times.

Let me explain the history in detail. For the rotation angle of the index table, see the slit 9-39-3l (C) attached to the outer circumference of the detection plate 9-1 that rotates together with the pix@gear]
A predetermined index rotation angle is detected by counting the number of slits that pass through the detection section of the detection switch 9-2 using the detection switch 9-2. Incidentally, the detection plate may be connected to a detection idle gear separately and attached to that gear. The gear to which the angle detection plate is attached is 1/N of index gear 7.
If the index table is set to rotate and the slits in the detection plate are made as many times as the number of divisions of the winding jig, the index table will rotate by one division when counted N times. For example, if the rotational speed ratio N of the gear is 3 and the gear is divided into 28 divisions, a detection plate having 28 slits is attached so that the gear rotates by one division every 3 counts.

In another example, even if the number of divisions is a prime number such as 23, if you replace it with a detection plate with 23 slits, the count will be 3 and the result will be L.
Since it rotates by one division, there is no need for complicated calculations in control, and it is possible to respond to changes in the number of divisions, etc.

Reference numeral 13 is a twist pin for hooking the taps between the coils to perform twisting, and is placed at the bottom of the winding wire 22)A, and the tip has a hook shape for hooking the coil taps. The detailed information is shown in Figure 9. In this figure, reference numeral 14 is for twisting a twist pin hooked with a twist mode. The twist mold 14 and the twist pin 13 are connected via a shirt 13-21. One end of the shirt 13-2 is formed with a hollow portion for receiving the slide piece 13-1, and the other end is connected to the twist mold 14 by a coupling 14-1. The slide piece 13-1 has a guide groove, and the twist pin 13 is fixed integrally with the slide piece 13-1.
The hollow portion formed in 13-2 is connected with a spring 15 by applying an appropriate preload. 15-1 is a spring presser.

A pin 13-3 protrudes into a groove provided in the slide piece and prevents the slide piece 13-1, which is integrated with the twist pin, from rotating and regulates the orientation of the seven prongs of the twist pin. By adjusting the strength of the spring appropriately, it is possible to prevent wire breakage due to the coil tap 16 being twisted and shortened during twisting, and when removing the tap from the hook after twisting, tap separator 7 (described later) is used.
It becomes possible to move the twist pin to the part where it is caught by the locking piece 71 of 0 without the tap coming off the hook part and without breaking the wire. The air cylinder 17 slides left and right to remove the coil tap 16t. After twisting, the seven twist pins are stopped in a fixed direction by the detection dog 13-4 and sensor 13-5.

Further, these twist a structures are configured to be moved up and down by an air cylinder 18.

Reference numeral 19 denotes a column supporting the upper apparatus to the wire winding and assembling station. A guide holder 20 is provided on the upper part of the column, and a guide post 21 is supported by the guide holder 20. Further, a slide base 22 is provided on the guide post 21 so as to be movable up and down by a guide bush 23, and the entire upper device of the winding and assembling station A attached to the slide base 22 is configured to move up and down. Volume J [i The entire upper device of station A is moved up and down by an air cylinder 24. A guide holder 25 is further provided on the top of the slide base 22, and a guide post 26 is supported by this guide holder 25. A system slide base 28 is supported on the guide post 26 by a guide bush 27 so as to be movable up and down by the operation of an air cylinder 29. Further, a ball bearing 30 is fitted to one end of the slide base 28. A core shaft 31 is press-fitted into the ball bearing 30 from below, and a fixing screw 32 is attached to the upper end of the core shaft 31 . Further, the first core shirt 31 is provided with a through hole 31-1 that passes through the top and bottom. A nozzle 31-2 is provided at the upper end of this winding core shaft 31, and a spline shaft 31-2 with splines formed on the outer periphery is provided at the center.
It is said to be 3. Also, a part of the lower end is a notch 31-4.
The guide reel 33 is installed in this notch 31-4.
are set up so that they can be transferred freely. Furthermore, a ball bearing 34 is fitted in the lower end opening.

Further, at the lower end of the single-volume core shaft 31, a column weight 31-5 is provided to balance a rotating nozzle 40, which will be described later.

Reference numeral 35 denotes a spline sleeve, a ball bearing 36 is fitted into the middle part of its outer periphery, and a pulley 37 is fixed to the upper end by a fixing screw 38.

Ru. Further, a rotary nozzle 40 supported by an arm 39 is attached to the lower end of the spline sleeve 35, and an electromagnetic wire, for example, an enamelled copper wire 4
1 is guided inside this rotating nozzle 40. especially,
This electromagnetic wire 41 is an enameled wire whose surface is coated with a heat-fusible coating material such as phenol oxide or butyral. 42 is installed as described below +m
This is a detent pin of the Mf 1-volume jig 43, which is attached to the tip of the air cylinder 44, and prevents the first-volume jig 43 from sliding upward or downward from the upper limit t4. It engages with the positioning notch 50-1 of the tool 43 and is prevented from rotating so that relative positional deviation between the first volume jig 43 and the rotary plate 8 does not occur.

The one-winding jig 43 is the main component (1) of the present invention, and is mounted on a shaft 45 that is rotatably supported by the ball bearing 34 fitted into the lower end opening of the core shaft 31. 9, supported in a co-moving relationship with the winding core shaft 31.
t, a coil spring 46 wound around the shaft 45 applies an appropriate pressurization, and the shaft 45 faces the rotary plate 8 with a predetermined gap therebetween.

The outer periphery of the lower surface of the first winding jig 43 is used to generate a component of force to push up the first winding jig 43 due to coil tension during coil winding, and during indexing of the rotary plate 8, which will be described later. The main oblique portion, which has an inclined portion 43-1 to maintain an appropriate positional relationship with the lower surface thereof, may be curved instead of straight.

In addition, the first winding jig 43 is provided with two spring pins 47 for forming a hexagonal coil, one at a position close to the center of the rotary plate 8 and the other at a far position. The spring pin 47 is made to be able to slide up and down, and when the spring pin comes into contact with a wound coil, a suitable pressurization is applied by the coil spring 48 so as not to damage the coil. .

The spring pressure of the coil spring 46 inserted into the shaft 45 and pressing the first volume jig 43 is several times stronger than that of the coil spring 48 inserted into the coil pin 47. The spring pressure of the coil spring 46 is set to an appropriate value depending on the diameter of the electromagnetic wire 41 to be wound (the wire's stiffness) and the tension applied thereto.

When a coil is wound on the lower part of the above-mentioned m1 winding jig 43, the coil tension generates a force that pushes up the first winding jig 43 at the lower inclined part of the first winding jig 43, and the coil spring 46 Push up the winding jig l against the pressing force to create a space where the coil becomes round and tight. Since a coil is formed there, if the coil 46 is too strong, the rotating plate 8 and the first
The space between the winding jigs 43 remains as narrow as it was at the time of crimping, and the first winding jig 43 cannot be moved upwards easily. It is not possible to wind the coil into a predetermined shape because the coil is in the way. Moreover, the coil shape becomes uneven between the beginning and the end of winding, and the coils are wound one after another so as to extend in the outer circumferential (horizontal) direction, making it impossible to form the coil into a predetermined outer circumferential shape.

If it is too weak, the coil will not stretch in the outer circumferential direction, but the coil thickness in the winding direction will increase.

As described above, it is difficult to form the coil shape into a predetermined shape.

49 is a slide plate, and the spring pin 47 is oriented at 11°.
The shaft 45 is threaded through the shaft 45 and screwed onto the shaft 45. As is clear from this configuration, when the shaft 45 slides, the upper surface of the slide plate 49 pushes up the flange of the spring pin 47, and the spring pin 47 protruding from the lower surface of the first volume jig 43 comes out and disappears. configured to be possible.

Reference numeral 50 denotes a cover provided on the upper surface of the first winding jig 43, which supports the spring pin 47 in a slidable manner, and whose central portion serves as a bearing boss for the shaft 45. Therefore, this cover 50 is manufactured from a sintered oil-impregnated bearing material. As shown in FIG. 5, the rotary plate 8 has a plurality of pins 5 equidistant from the center of rotation of the rotary plate 8 and slightly outside the inner spring pins 47.
Similarly, a plurality of pins 52 are installed at the same distance from the center of rotation of the rotary plate 80 and slightly inside the outer spring pins 47.

In one embodiment of the present invention, these pins 151 and 52 each have 28 pins, and cooperate with the three pins 47 to wind a heptagonal coil as shown in FIG. It has become. In this case, the coils are not wound around adjacent pins, but around four pins apart.

Reference numeral 53 denotes a recess provided below the first volume jig 43, which is made of an arc shape γ1 having the same radius as the pin 51.52, and is considerably wider than the diameter of the pin 51.52. The depth is set so that the tips of the pins 51 and 52 do not touch the upper bottom of the recess 53 even when the first roll jig 43 is pressed against a discharge plate 54 to be described later. The ejection plate 54 is connected to the pin 51.5.
r'
; iJ is arranged on the concave portion 8-2 of the rotary plate 8.

Reference numeral 55 denotes a disc-shaped @2-width jig that serves as a guide for winding the electromagnetic wire 41 fed out from the rotating nozzle 40 around a predetermined pin, and also allows the given coil 41A to rotate without being completely wound. It has a holding action to prevent it from floating above the plate 8, and a part of the outer periphery is attached to the ball 56 by a support pin 56-1 so that it can be opened and closed freely. .

57 and 58 have the same radius as the pins 51 and 52, arcuate edges formed on the lower surface of the disc-shaped winding jig 55, and the same width as the recess 53. A coil spring 59 is wound around the outer periphery of the mounting ball 56 to hold the second volume jig 55 at a predetermined height. 56-2 is a long groove that allows the support pin 56-1 to move up and down by a predetermined distance, and is attached to the ball 56. This coil spring 59 pushes the second winding jig 55 upward in advance, and when indexing the index table 60 after winding, maintains an appropriate gap between the second winding jig 55 and the rotary plate 8. When the wound coil 41A enters the second winding jig 55, the notch 55-1 of the second winding jig 55
This is to prevent the coil 41A from hitting the side surface of the coil 41A and from rubbing the coil 41A strongly against the lower surface of the second winding jig 55, thereby allowing smooth indexing. Long 1:'t 56
By supporting the coil spring 59 in combination with the coil spring 59, the second volume jig 5 is
5 and the rotating plate 8, the wound coil 41
It becomes possible to shape A into a flat shape. The part supported by the coil spring is part of the second volume jig 55, and the second volume jig 55
1 and rotating plate 8 so that there is no gap. When the rotary plate 8 indexes, the gap on the side where the coil 41'A under the first volume jig 43 enters is made larger, so that the fully wound coil 41A comes out under the first volume jig 43. Reduce the gap on the opposite side.

That is, in FIG. 5(A), by reducing the gap on the left side of the first winding jig and increasing the gap on the right side, the coil 41
Indexing is possible without A hitting the side and without problems such as coil disturbance.

The upper surface of the discharge plate 54 is overcoated with Teflon or ceramic to prevent short-circuit damage even if the coil short-circuits during electrical heating.

This prevents the dissipation of heat during electrical heating and makes it easy to release the coil from the mold when the coil is discharged after winding. Further, the lower surface of the second volume jig 55 is also overcoated in the same manner as described above. Reference numeral 55-1 denotes a fan-shaped notch formed in a part of the second winding jig 55, and this notch 55-1 is slightly smaller than the six pitches of the pins 57 and 58.

This is to prevent the coil from being wound on pins outside this pitch when the coil is wound with a pitch of 4. This notch 55-1 allows insertion of the first volume jig 43, but the electromagnetic wire 41 is inserted into the first volume jig 43 between them.
A gap G is provided along the outer circumferential surface of the material to allow the material to fall. The angular pitch of the lower end flat part of the first winding jig 43 is also larger than the pitch (4 pitches in this case) of the pins 51 and 52 around which the coil is wound. Notch part 55-1
As is clear from FIG. 5(A), a diagonal cut 55-2 is provided from the lower surface to the side surface to facilitate the insertion of the wound coil 41A into the lower part when indexing the rotary plate 8. A steel pole 60-2 is incorporated in the center of the index table 60, which has a through hole through which a twist pin 13 for coil tapping can be moved up and down, and is pressed by a spring 60-3. A recess 60-1 is provided in the index table receiving portion to maintain the positional accuracy of the index. 70 is a tap wire (later).Tap wires interfere with each other during winding work, which will be described later.
When the twist pin is raised, it is held in a fixed position so as not to catch the tap line that has already been processed, and is indexed integrally with the index table. still,
The tap separator 70 has a planar shape shown in FIG. 3(A).

That is, a number of locking pieces 71 corresponding to the number of taps determined by the number of coils 41A to be wound are fixed inside the outer ring 72 toward the center. As shown in the figure, a triangular head 73 is formed at the tip of the locking piece 71.
1 is itself made of an elastic body. This locking piece 7
1 can also be made from synthetic resin, but the one made by bending piano wire had stronger elasticity and better wear resistance. When the coil tap 16 is inserted, the locking piece 71 bends in a predetermined direction to permit insertion, and returns to the parent's position after insertion to prevent the tap from returning to the inside.

62 is a coil winding start clamp, and 63 Fi is a winding end clamp, which are provided on the index table 60. After one winding is completed, the winding start and winding end of the coil are clamped by the clamps 62 and 63, but when the clamps are clamped, the clamping teeth of the clamps 62 and 63 break the coating of the electromagnetic wire 41, Internal core wire (copper m)

Therefore, the clamps 62, 63 and the electromagnetic wire 41 are electrically connected. In such a state, the clamp 62.6
3, when a predetermined amount of current is applied to the coil 41A, the wound coil 41A generates heat, the heat-sealing coating of the coil 41A melts, and the electromagnetic wire 41A forming the unit coil 41A melts.
This electromagnetic wire 41 and the electromagnetic wire 41 forming the other coil 41A are welded together. When the coil is cooled for a predetermined period of time, the heat-sealing coating material is cured, and a hard and regularized coil winding set in which a large number of unit coils 41A are superimposed is obtained. 64 is the clamp 62.6
3, which is movable up and down by an air cylinder 65.

A pressing block 66 is provided at the lower end of the air cylinder 65, and the pressing block 66 includes a pressing body 66-1 that presses the second volume 70 tool 55 downward when the coil 4LA is heated 71D, and a pressing body 66-1 that presses the second volume 70 tool 55 downward. Notch 5 of jig 55
5-1, and a fan-shaped suppressor 66-2 that directly applies a pressing force to the coil 41A through the coil 41A.

As the suppressing block 66 moves forward, the suppressing body presses the second volume jig 55, and the coil spring 59 and the long groove 56-2
By reducing the gap between the 2-wrap jig 55 supported by the coil 41A and the rotary plate 8, the 42-wrap jig 55 is completely passed through.
Press. Further, the notch 55-1 of the second winding jig 55 presses the coil 41A with the pressing body 66-2, thereby uniformly pressing and shaping the entire coil into a flat shape. In this state, the coils can be fixed in a predetermined shape by thermally fusing them together in the manner described above.

Reference numeral 67 is a column that supports the suppressing energization heating shaping section and the six poles of the conductor, and 68 is a timing belt that transmits rotation to the winding core shaft 31. A pulse mode (not shown) or the like is used to generate one rotational force. A position detection sensor (not shown) for always stopping the nozzle 40 at a fixed position is installed. It is equipped.

78 is a commutator holder, which holds the commutator. This commutator holder is provided with a guide groove 79 for guiding the coil tap to the connection groove 77 of the commutator piece 76. Further, the outer circumferential portion of the guide groove 79 is provided with a widening portion 80 for guiding the coil tap into the guide groove 79 and making it easier to remove the coil tap. The range in which the guide groove is provided is the range indicated by L, and each guide piece is integrated at its lower side.

Reference numeral 81 denotes a lifting base shown in FIGS. 11 and 12, which is lifted and lowered by a cylinder (not shown). The commutator holder 78 is attached to a mounting base 84 which is rotatably disposed on this elevating base by means of bearings 82 and 83, and moves up and down together with the elevating base 81. As the commutator holder rises, the coil taps, which are held separately and spread out toward the bottom, are guided by the widening portions 80 of the guide grooves 79 and guided into the guide grooves 79. 85 is a connecting pin that fits into the connecting hole 86 of the index gear on the rotating plate side.

In the above, the unit on the turntable 3 is the first
One winding station A as shown in figure (A)? It is divided into a coil forming solid bed station B1" by heating, a two-way station 7C, and a discharge station D.
By setting the entire minimum length of the stainless steel and combining these with -1.d, it is possible to obtain a winding machine with twice the manufacturing capacity or more. In other words, Tanigumi 4d station A is arranged at the starting point of the turntable 3.

Coil forming and fixing station B is placed at 11t at 90 degrees from the starting point, and 180 degrees from the starting point.
The connection station C is placed at a position of 270 degrees from the starting point, and the discharge station D is placed at a position of 1ζ at a distance of 270 degrees from the starting point. At the ejection station, this is not done unmanned, but the ejection plate 54 is connected to the index table 60 by a cylinder (not shown). The rotary plate 8 is pushed up by the cylinder pin 74 through the insertion hole 60-4, and the coil 41A wound around the pins 47, 51 and 52 can be easily removed from these pins.

Note that the discharge can also be performed after the connection process at the connection station. Next, the operations in the above-mentioned embodiment will be sequentially explained.

When the start button (not shown) is pressed, the guide pin 6 of the turntable 3 is removed, the turntable 3 is rotated by the required angle by the gear mode 5, and the rotating plate and second volume jig from which the completed coil has been taken out are moved to the discharge station. A winding and assembling jig such as the above is transported to the winding and assembling station A. Subsequently, the guide pin 6 is reinserted and the wire winding jig is placed at a predetermined position. Index gear 7 and gear 9 continue to mesh, rotate until the winding start clamper on the winding assembly jig comes to a predetermined position, and then stop (50'26' in this example).
) Next, operate the cylinders attached to each °C.
> Set the 1θ Sdenoyon as shown in Fig. 2, transfer the terminal wire from the clamper 69 of the winding and assembling station to the winding start clamp 62 on the winding and assembling jig, and clamp it as shown in Fig. 2. .

The state shown in Fig. 2 is a state in which 15 lines are possible. That is, the first volume jig 43 enters the notch 55-1 of the second volume jig 55, and the coil spring 46 brings the first volume jig 43 close to the discharge plate 54 surface with a slight gap. state. At this time, the lower ends of the three spring pins 47 are in contact with the surface of the discharge plate 54 with a predetermined pressure due to the urging force of the coil spring 48. As mentioned above, pins 51 and 52 are installed on the rotary plate 8,
By means of these pins 47.51.52 the hexagonal coil 4
1A winding becomes possible.

In this state, when the winding stepping mode (not shown) rotates, the rotational force is applied to the pulley 37. spline sleeve 35
The rotational nozzle 40 is rotated. Rotating nozzle 40
As the electromagnetic wire 41 is rotated, an appropriate tension is applied to the electromagnetic wire 41 fed out from a coil boppin (not shown) by a coil tension mechanism (not shown), passes through the core shaft 31, is guided to the guide reel 33, and is further rotated. It passes through the nozzle 40, cleans the side wall surface of the first winding jig 43, and is sequentially wound around the pins 51 and 52 of the rotary plate 8. At this time, the winding core shaft 31 of the first winding jig 43 is in a lowered state, and the spring pin 47 protrudes downward and is in contact with the discharge plate 54, so that the coil is
1.52 and this spring pin 47, and its shape becomes a heptagonal shape as shown in FIG.

After being wound a predetermined number of times, the rotating nozzle 40 stops at a fixed position. It is very difficult to wind the coil 41 tightly in a narrow space (especially the pitch of the pin 51). In this case, the first winding jig 43 is pressed with an appropriate force by the coil spring 46, and the electromagnetic wire 41
Because of the relationship in which appropriate tension is given to
The coil 41A is caused by a component of the force acting on the lower slope of the winding jig 43.
As the coil 41A is wound, the first winding jig 43 rises, albeit slightly, and the coil 41A is wound in an orderly manner. Also, at this time, (1) the fan-shaped element of the 1-3 jig 43 and the notch 55-1 of the second winding jig 55 are set in an appropriate dimensional relationship, so that winding can be ensured around the predetermined pins 51 and 52. .

Predetermined number of times! ! 5, the air cylinder 18 is operating. The twist pin 13 rises through the center through hole of the index table 60 and rotary plate 8. By further winding the rotating nozzle 40 about one turn, the magnetic wire 41 (7a) is hooked to the hook portion of the twist pin 13. Subsequently, the air 7/tick 8 floats downward.

In this way, when the coil winding and winding of IA are completed,
Operate the air cylinder 29 to move the winding core shaft 31 to the third position.
Raise it halfway up as shown.

When the winding core shaft 31 rises at the middle IJ';l''J, the three tin ring pins 47 that have been vulgarly lost in the first winding jig 43 are connected to the coil springs 48, respectively, as shown in FIG. It is pulled up by the slide plate 49 against the spring force of , and drawn into the 41-winding jig 43.

By moving the winding core shaft 31 into the internal upper bar, the slide plate 49 fixed at the tip also rises.Although the AIIta tool 43 is pushed downward by the coil spring 46, the cover 50 hits the slide plate 49. Stop at a certain point.

By adjusting the intermediate rise amount of the winding core shaft 31,
The gap between the lower surface of the first volume jig 43 and the rotary plate 8 can be set in a Kyogen manner. By appropriately setting the rising height of the bowl 1-containing jig 43 within a range in which the tips of the pins 51 and 52 set on the rotary plate 8 do not come off the recesses 53 provided in the first volume jig 43.

The pressing force acting on the coil 41A is removed, and the rotary plate 8 can be indexed smoothly without the coil 41A dislodging from the pins 51, 52. Subsequently, when the stepping mode lO is operated, the intex is performed at a predetermined pitch (115° 43' since the present invention uses 28 coils, a 6-pole magnet, and a wave winding connection).

At this time, the set of coils 41A that have been wound are still prevented from floating upward due to springback by the first winding jig 43.
Insert the pin 5 into the gap between the 42-volume jig 55 and the discharge plate 54.
1.52 so that it can be fed smoothly.

At this time, as described above, the relationship between the 2' volume jig 55 and the 2' volume jig 55, which is held with varying gaps with the rotary plate 8, is as shown in FIGS. 5 and 5(A). 43 has already been wound and is under the second winding jig 55.
The gap is larger than the gap on the bottom surface of the second volume jig 55 on the side where the coil 1A slips into, and the bottom surface of the second volume jig 55 on the side where the coil 41A wound on the bottom surface of the first volume jig 43 enters. By maintaining an appropriate play relationship so that the gap is smaller than that of the coil 41A when indexing the rotary plate 8.
can be moved to the lower surfaces of the first volume jig 43 and the second volume jig 55 without contacting the side surfaces thereof, allowing smooth indexing.

As mentioned above, if you make a diagonal cut from the side to the bottom, it will be easier to create this kind of relationship.

Furthermore, the second volume jig 55. Indexed above 11
It is made of metal and has a corresponding weight in order to press the several sets of coils sent between the two with appropriate pressure.

When the first Intex is finished in this way, the third
The intermediate position 1.91 winding jig 43 shown in the figure is lowered again to the state shown in Figure 2, and the next set of coils 41A winding pins 5
1.52, and rotate the rotary nozzle 40 again to wind the coil 41A.

When indexing of the rotary plate 8 begins, the twist mode 14 rotates and the coil tap 16 is twisted a predetermined number of times. When the twisting is completed, the twist pin stops facing in a certain direction, and then the air cylinder 17 is operated to move the twist pin 13 left and right to remove the coil tap 16 from the hook portion.

The direction of movement of the cylinder 17 is the intermediate position between the previously wound coil and the next wound coil, and the direction of connection to a commutator, which will be described later. As mentioned above, this coil tap 16 prevents the taps from collapsing and interfering with each other, and also prevents the twist pier 1.
When the coil tap 3 rises, the coil tap separator L/- is used to prevent the already processed tap 16 from getting caught or deformed 71).
It is held in a fixed position at 70 pm.

A predetermined number of coils 41A17), S
When the line ends, the 21'>1-volume jig 43 rises and the turntable moves, but when the first-volume jig 43 rises immediately after the line ends, the wound coil group floats up. Therefore, when the winding is completed, the air cylinder 29 operates to raise the winding core shaft 31 halfway up, burying the spring pin 47 of the first winding jig 43 in the first winding jig 43, and then temporarily A predetermined index (64°1 in the present invention)
7').

By doing so, the last coil 41A is the 27th! +The coil group is held in the jig 55 and is prevented from floating. However, at this time, -1 wrapped in the middle
The coil 41 appears in the notch 55-1, but this coil is held down by the next coil wound over this coil, so it does not float up. Indexing is done smoothly. After indexing by a predetermined amount, the end of the coil 41 is clamped by a clamper 63 and cut by a cutting tool (not shown). The terminal wire on the boppin side is held by a clamper 69 provided at the winding and assembling station A. In this state, the air cylinder 24 is operated, and the entire upper device of the winding and assembling station is moved upward as shown in FIG.

At this time, since the first volume jig 43 is in a free state, the air cylinder 24 operates a moment earlier, the moya cylinder 44 operates, and the detent 42 engages with the notch of the blind cover 50, and the first volume jig 43 is in a free state. This is used to prevent the tool 43 from rotating. Thus, the turntable 3 is indexed, for example, by 120 degrees,
The 41-member coil group moved to the next coil forming and fixing station B.
sent to. At this station B, the air cylinder 65 is operated and the coil 41 subassembly is pressed and shaped by the suppression block 66, and at the same time, the energizing electrodes 64 are joined to the clampers 62, 83 and energized. Since the pressing block 66 has a pressing body 66-1 that presses the second volume jig 55 and a fan-shaped pressing body 66-2 that directly presses the coil 41A through the notch 55-1, the pressing shaping of the coil 41A is almost perfect. can be done. During this time, a series of wire winding operations are repeated at the winding and assembling station. After being energized for a predetermined period of time, the energization is stopped, but after that the air cylinder 65 is left in the pressed and shaped state for a certain period of time (25 to 30 seconds), and the air cylinder 65 returns to its original upper position. When a series of winding steps at the winding and assembling station are completed, the turntable 3 is further indexed by 90 degrees. The 41 coils thus shaped and heated and fixed are sent to the next connection station. Since the coil after shaping and heating and fixing is welded and hardened with a heat-sealed covering material, the coil retains its shape even if the second winding jig is removed. FIG. 11 is a view after the second volume jig 55 is opened using the support pin 56-1 as a fulcrum, and the second volume jig 55 is not shown. If the elevating base 81 is raised in this state, the first
As shown in FIG. 2, the ejection plate 54 is pushed up using a push-up pin 87 to ensure an appropriate gap between the rotary plate 8 and the ejection plate 54. At this time, the amount of thrust is that the coil 41 is pushed up by the pin 51.5.
The range should not deviate from 2. , and commutator holder 78
Push up the commutator 75, which is attached to the holder, so that the connecting groove 77 is at the height of the insertion punch 89. At the same time, the connecting pin 85 fits into the connecting hole 86 of the index gear 7.

During winding, the coil taps are twisted by the leads between the coils connected to the same connection groove of the commutator piece 76.

Further, the arrangement corresponds to the arrangement order of the connection grooves 77 of the commutator piece 76, and is arranged in the same order, and is separated by the tap separator 70 so that the order will not be disrupted or tangled.

On the other hand, the outer periphery of the guide groove 79 of the commutator holder 78 is provided with a widening part 80 to make it easier to guide the coil tap, so that when the commutator holder 78 rises, the guide groove 79 is separated and held in a state where it expands toward the bottom. coil tap 1
6 is guided from the guide wiping part 80 to the guide groove 79.

In this state, the insertion punch 89 is advanced toward the connection groove 77 of the commutator 75 through the gap between the discharge plate 54 and the rotary plate 8 and between the pins planted on the rotary plate. As described above, the coil tap 16 is guided by the expanded portion 80 and positioned in the guide groove 79 when the commutator holder is raised, so the coil tap 16 is pushed into the connection groove 77 of the commutator 75 by the insertion punch 89. It will be done. If the insertion bolt and punch 89 are shaped like a cross except for the tip, and the guide groove 91 is also shaped like a cross, the coil tap located in the widening part will also pass through the guide groove 79 and into the connection groove 77. is inserted. Also, by advancing the cutter 90 toward the commutator piece slightly later than the insertion punch 89,
Coil taps located below the cutter 90 are cut. By moving the clamper 92 forward and closing it while inserting and cutting these coil taps,
Clamp the cut coil tap. Subsequently, the insertion punch 89, the force 90, and the clamper 92 are retracted. A receiving box (not shown) is placed at the rearward end position of the clamper 92, and by opening the clamper, the coil tap remaining material after cutting is stored in the receiving box.

In this state, connect index gear 7 to the drive section in the same way as when winding. If you rotate the index,
At the same time as the coil 41 and the coil tap 16 are indexed, the mounting base, which is rotatably mounted and connected through the connecting pin 85 and the connecting hole 86, is indexed together with the commutator 75, and the coil tap and commutator to be connected next are indexed. The connecting groove is inserted into the punch 89 and the cutter 90. Move to a position opposite the clamper 92. In this case, since the winding is different, the index angle only needs to be indexed by one pitch. The index of the positive flow element holder may be driven separately from the index of the rotary plate, but if the index is not indexed in synchronization, there is a risk that force will be applied to the connected portion. It is structurally simpler to connect them using the same drive.

Subsequently, the insertion punch 89, cutter 90, and clamper 92 move forward and backward. By repeating the rotation of the index gear 7, the coil taps 16 can be automatically inserted and connected into the connection grooves 77 one after another.

The coils wound with this device have coil taps with a common lead at the beginning and end of the coil, but all other coil taps can be connected automatically.

After the connection process is completed. When the index gear is in the normal position and the lifting base 81 is lowered, the commutator 75 remains connected to the coil through the connecting coil tap, and only the commutator holder 78 is lowered.

The first work system is completed by automatically or manually setting a commutator for the next work in the commutator holder 78. In addition, the projecting pin 87 and the connecting pin 85 are connected to the elevating base 81.
Since it descends together with the winding jig, the turntable is separated from the winding jig, and the turntable becomes ready for indexing, and the $2 winding jig 55 is returned to its original state and further indexed by 90 degrees.

During the connection process, another coil is being wound at the winding station.

Furthermore, the number of stations can be increased, or even if the number of stations is not increased, the parts corresponding to the punch and cutter shown in Fig. 12 can be replaced with separately provided electrodes, and with this electrode pressed against the commutator piece, a predetermined current can be applied. By flowing, electrical connection by fusing is also possible.

Naturally, this is carried out after the coil tap 16 is connected to the connection groove 77 of the commutator piece 76 using the punch 89 or the cutter 90 or the like.

Specifically, an electrode corresponding to a punch is applied to the surface of the commutator piece 76 which has been crushed so as to bury the coil tap 16 with a punch 89, and an electrode corresponding to a forceps is applied to the surface of the commutator piece 76 so as to bury the coil tap 16. It comes into contact with the surface of the commutator piece away from the crushed part. However.

By passing a large electric light through the electrode for a short time, the buried portion of the coil tap 16 is heated, the coating of the coil tap 16 is melted, and the false piece 76 and the coil tap 16 are electrically connected.

At the next discharge station/, the second volume jig 55 is opened using the support pin 56-1 as a fulcrum, and the discharge plate 54 is pushed up by an air cylinder (not shown), thereby completing the flat coil unit. can be taken out. The coil can be taken out after forming and connecting, either manually or automatically, but in either case, the ejection plate 54 makes it easy to take out the coil, which is preferable.

It is preferable that the spring force of the coil spring 46 that presses the tool a 43 is i) adjustable by the rotational speed of the idle rotating nozzle 40 and the tension applied to the electromagnetic wire 41. As a result, the wire diameter of the electromagnetic wire 41 to be handled is not specified.
