Be composed.

[0003] This stator coil has a problem that the stator core becomes longer as the capacity of the turbine generator increases,
The stator coil length is also very long.

[0004] To manufacture such a stator coil,
The wire wound on the wire drum is pulled out, cut into an arbitrary length, and when an arbitrary number is cut out, the wires for one coil are manually bundled as shown in FIG. Label dislocation forming was performed from an arbitrary position by a label dislocation conductor manufacturing apparatus while the wires were fixed to a feeder and bundled.

A plurality of pairs are arranged at intervals of 80 cm, and arrows 212 are intermittently arranged.
A, rotates in the direction of 212B. Further, a pair of step forming devices 213A and 213B are arranged adjacent to both sides of the strand bundle 210. In this case, the step forming device 213
For A and 213B, there is a case where only one of two pairs is used or a case where both pairs are used depending on the kind or combination of the element wire conductors to be used.

The step forming devices 213A and 213B are fixed to receiving ends 214A to 214B at their ends, respectively, and slide 216 reciprocally slides in the directions of arrows 215A and 215B, that is, the width direction of the dislocation conductor by a driving device (not shown).
A, 216B. This slide 216A, 2
16B, the push piece 2 faces the receiving pieces 214A and 214B.
17A and 217B are mounted, and reciprocally slide in the directions of arrows 218A and 218B, that is, in the height direction of the dislocation conductor, by a driving device (not shown).

The receiving pieces 214A and 214B and the pushing piece 217
Each of A and 217B has a formed portion corresponding to the wire size for performing step forming on the wire located at the end in the width direction in each case. It is to be noted that a receiving piece and a pressing piece having different molding portions are attached according to the respective wire dimensions of the wire conductor.

[0008] In the figure, reference numeral 220 denotes a state in which strands of one coil are bundled and one end thereof is gripped, and the strands to be subjected to step forming are located exactly at the step forming apparatuses 213A and 213B.

Since “slip” also occurs, the accuracy of the operation further decreases. Therefore, the label dislocation pitch cannot be narrowed, which hinders the performance improvement of the turbine generator. In addition, the label dislocation forming portion has a trouble of manually inserting thin insulators one by one in order to prevent a short circuit, and there is a problem that the number of working steps is extremely large.

As a first embodiment of an apparatus and a method for manufacturing a label transposition conductor of a stator coil in a rotating electric machine according to the present invention, a case where the present invention is applied to the manufacture of a stator coil of a turbine generator in a power plant will be described.

FIG. 1 is a perspective view showing the entire configuration of a label coil conductor manufacturing apparatus for a stator coil.

The apparatus for producing a label dislocation conductor shown in FIG.
A wire supply unit 10 having a wire loosening prevention unit 10a and a wire break detection unit 10b for detecting a wire break, a wire sending unit 20 for sending a wire supplied from the wire supply unit 10, A wire bending correcting unit 30 for correcting the bending of the wire sent from the wire sending unit 20, and a heating unit 5 for heating the insulating coating of the wire straightened by the wire bending correcting unit 30.
0, an insulation coating removing unit 53 for removing the insulation coating of the heated wire, a wire cleaning unit 65 for cleaning the wire removed by the insulation coating removal unit 53, and precisely sending the cleaned wire. Precision delivery cutting section 70 for cutting by cutting, the remaining material discharging section 8 for discharging the remaining material of the strand cut by the precision delivery cutting section 70
1. Consisting of a drawer 90 for drawing a wire from which residual material has been discharged in order to perform a label transposition, and these are disposed in the right column of a frame configured in two rows on the left and right with respect to the drawing direction of the wire. Have been.

In this case, the wire sending section 20, the wire bending correcting section 30, the heating section 50, the insulation coating removing section 53, the wire cleaning section 65, the cutting section 70, and the remaining material discharging section 81 are mounted on the same frame. Each of them is placed to form one station.

In addition, one strand stand loader 107 and three loaders 106 are arranged on the ceiling portion of the frame corresponding to the strand drawing section 90 at regular intervals in the strand traveling direction. In addition, one positioning control loader 151 and two loaders 152 and 15 are provided on the ceiling of the frame corresponding to a position between the wire supply unit 10 and the residual material discharging unit 81.
3 are arranged at regular intervals.

Further, on the floor surface on the left column side with respect to the direction of drawing out the strands of the frame, a conveyor 1 having a long conveyor belt 163 and a table (not shown) for supporting the conveyor belt 163.
62 are provided.

FIG. 2 is a perspective view showing in detail an enlarged configuration of the wire supplying section 10. As shown in FIG.

As shown in FIG. 2, in the wire supply section 10, a wire 11 is wound around a wire drum 12 in a state where the outer periphery of a rectangular copper wire is subjected to insulation coating. The wire drum 12 has a wire slack preventing means 10a, which is connected to a rotating shaft 13 inserted into the wire drum 12 so that the wire 11 wound around the wire drum 12 is not loosened when the wire is pulled out. A brake 14 for preventing over-turning is provided, and a strand 11 is hung on an idler 15 provided on a side opposite to the traveling direction to take a bending habit and to prevent slack of the strand before and after the strand drum 12. Is configured to be tensioned by an air cylinder 17 via a link mechanism 16.

The wire break detecting means 10b is linked to the wire loosening preventing means 10a. When the wire 11 is on the wire drum 12, tension is applied to the wire 11 and the wire 11 is pulled in the traveling direction. Therefore, the air cylinder 17 does not move to the retreat limit due to the resistance of the wire 11 when the air cylinder 17 moves to the retreat limit. However, when the wire 11 disappears from the wire drum 12, the tension of the wire 11 is pulled. The resistance due to the force disappears, and the air cylinder 17 moves at a stretch to the retreat limit.
When the air cylinder moves to the retreat limit, an electric signal is input to a monitoring device (not shown) by the operation of the limit switch 18 to notify that the wire 11 has disappeared from the wire drum 12.

Further, as means for detecting the connection of the strands 11, a photoelectric sensor (not shown) is used which can distinguish the color of the connection portion from a color different from that of a normal insulating coating. Further, in order to always keep the distance and the position between the element wire 11 and the photoelectric sensor (not shown), it is constituted by an adjustable guide roller (not shown) that can correspond to an arbitrary element wire size.

FIG. 3 is a perspective view showing in detail a configuration in which the wire sending section 20 and the wire bending correcting section 30 are enlarged.

The strand sending section 20 feeds the strand 11 drawn from the strand drum during the setup to the cutting section 70 (see FIG. 1), and includes a driven pulley 21, a driving pulley 22, a transport belt 23, A drive motor (not shown), a base 24 on which they are mounted, an air cylinder 25 for vertically moving the base 24, and a guide 2 for moving the base 24
6.

In such a wire feeding section 20, the wires 11 drawn from the drum are placed on the belts 2 arranged vertically.
3, the upper belt is lowered by the air cylinder 25, the driving belt 22 is sandwiched between the upper and lower belts, and a driving force is applied to the driving pulley 22 to feed the element wire 11 to the cutting section 70. Further, the drive pulley 22 can be pulled out toward the strand drum 12 by reversing the rotation of the drive pulley 22. In addition, by using a belt to drive the wires, it is possible to prevent the wires whose outer surfaces are coated with insulation from being subjected to a local force at the time of drawing, thereby preventing the insulation performance of the portion from deteriorating. ing.

The wire bending correcting section 30 has rollers arranged alternately in front and behind when viewed from the operator side. That is, four fixed straightening rollers 31 are arranged on the rear side, and three movable straightening rollers 32 are mounted on the front side of the operator side.
4 to adjust the pushing amount of the movable straightening roller 32 arranged on the operator side by a screw 33 with a handle in order to cope with the difference in the wire size and the difference in the bending habit. The bending of the flat wire 11 in the width direction can be corrected. In this case, the movement correction roller 32 is guided by the toggle clamp 35 to the guide 3.
6 to move back and forth so that the wires 11 can be easily passed through during setup.

In the thickness direction, rollers are arranged alternately up and down. That is, four fixed straightening rollers 37 are arranged on the upper side, and three movable straightening rollers 38 are arranged on the base 40 on the lower side. Of the correction roller 38 can be adjusted by an arbitrary feed of the screw 39 with a handle. The movable correction roller 38 is configured to be movable back and forth on a guide 42 by a toggle clamp 41 so that the strand 11 can be easily passed through at the time of setup.

The wire bend correcting units 30 have the same configuration and are arranged in two upper and lower stages. This is because, for example, when a combination of a solid wire and a hollow wire having different wire thicknesses is used, the wires can be drawn out in the arrangement order set in advance by an operation panel (not shown).

FIG. 4 is a perspective view showing in detail a configuration in which the heating section 50 and the insulation coating removing section 53 are enlarged.

As shown in FIG. 4, the heating unit 50 is provided with torches (not shown) above and below the place where the wire passes, and usually prevents the torch from being heated from the flame of the torch (not shown) by a shutter 51. When the part of the peel length set on the board comes to the position of the torch, the shutter 51 is automatically turned on.
Are opened by the air table 52 to heat the strands. For the same reason as described above, the heating unit 50 has the same configuration and is arranged in two upper and lower stages.

Further, as shown in FIG. 4, the insulating coating removing section 53 can be divided into two directions, ie, a wire width direction and a wire thickness direction. That is, the stripping of the strands 11 in the width direction is performed by installing two wire brushes 54 on the left and right sides in the feed direction, each of which has a drive motor 5 whose rotation direction is opposite to the feed direction.
7 is provided. The stripping of the strands 11 in the thickness direction is performed by installing two wire brushes 56 in the upper and lower directions in the feed direction, each of which has a drive motor 57 whose rotation direction is opposite to the feed direction.

Since the stripping of the wire 11 is in an arbitrary range, the wire brushes 54 and 56 need to be normally released (not contacted) with the wire 11. For this reason,
The wire brushes 54 and 56 are made to escape from the wire 11 by a rack and pinion (not shown) and an opening and closing mechanism driven by an air cylinder. In this case, the opening and closing mechanism is the wire width,
It also has an adjustment function when the strand thickness changes.

Further, when hundreds of strands 11 are peeled off, the outer diameter surfaces of the wire brushes 54 and 56 are worn out. Therefore, the wire brushes are polished and reused. May be used. At that time, the center lines of the wire 11 in the width direction and the thickness direction do not match the center lines of the wire brushes 54 and 56, and the finish of peeling is deteriorated. I am prepared to respond.

Further, in order to be safe and prevent the removed insulating coating from being scattered, a protective cover 60 for the width direction brush and a protective cover 61 for the thickness direction brush are provided at the boundary surface in the insulating coating removing portion 53. . Wire brush 5 in width direction
In No. 4, a transparent resin cover (for example, made of vinyl chloride) is provided on the upper surface and on the front side of the wire brush 56 in the thickness direction, so that the wire brushes 54 and 56 can be reduced and the wire 11 can be peeled off. You can check it immediately.

When it is confirmed that the wire brushes 54 and 56 have been reduced due to wear, the push-in amount of the screw with a handle (not shown) is adjusted so that the opening / closing mechanism of the wire brushes 54 and 56 driven by a rack and pinion and an air cylinder (not shown). The amount of operation is changed so that adjustment can be made in accordance with the reduction due to wear of the wire brushes 54 and 56.

FIG. 5 is a perspective view showing the details of the configuration in which the element wire cleaning section 65, the precision feeding and cutting section 70, and the remaining material discharging section 81 are enlarged.

As shown in FIG. 5, the wire cleaning section 65 is a cleaning brush 66 in which soft hairs are implanted on the upper and lower sides through which the wire passes.
Is installed, and a rotary shaft of a brush (not shown) is directly connected to a drive motor (not shown). When a portion having a peeling length set in advance by an operation panel (not shown) comes to the position of the cleaning brush 66, the brush automatically rotates. , Cleaning.

The precision sending and cutting section 70 is a section for precisely sending out and cutting the wire 11 to an arbitrary length.
A timing pulley 71 having an AC servomotor (not shown) and a driven timing pulley 72 having no driving source are mounted on the rear side (the right side in the figure) of a feed belt, and a timing belt 73 coated with a high friction cloth is provided on both sides. The hooks are arranged above and below the base 74 so that the lower portion is fixed, and the upper portion is movable vertically along the guide 75.

When the element wire 11 is sent out in the precision sending / cutting section 70, the upper part is lowered on the guide 75 by the driving of the air cylinder 76, and is sandwiched between two upper and lower belts to be sent. The length of the wire 11 to be sent is managed by the number of pulses of an encoder of an AC servo motor (not shown) provided in the drive timing pulley 71.
In addition, a timing belt 7 coated with a high wear cloth
Because it is used in combination with 3, the feed can be performed with extremely high precision.

The wire 11 is cut by a cutting blade 77 provided at the lower end of the hydraulic cylinder 78. The cutting blade 77 moves up and down on the guide 79 to prevent the wire 11 from rising and being displaced in the longitudinal direction. The vicinity of the location is clamped by an air cylinder 80 with a guide. The precision sending and cutting section 70 also has the same configuration and is arranged in two upper and lower stages for the same reason as described above.

The remaining material dispensing section 81 is composed of a dispensing table 82, a guide plate 83 for dispensing the short cut wires 11 traversing the dispensing table, and an air cylinder 84 which is a driving section of the guide plate 83. Tunnel type guide 8 for surely sending the wire 11 to the wire drawer 90
5 is comprised.

The purpose of the remaining material discharging section 81 is to perform the cutting and positioning of the wire 11 after returning to the home position by a control device (not shown) at the time of turning on the power, and to perform a plurality of discarding cuttings at a certain appropriate length. This is because it becomes residual material and must be paid out.

Also, as described with reference to FIG. 2, when the wire 11 has run out of the wire drum 12, the device is also temporarily stopped and connected to the wire 11 of the new wire drum 12 by taping. If the part is detected by an identification sensor (not shown), it is compared with a wire length set in advance on an operation panel (not shown), and is necessary if sufficient (for example, there is no wire connection portion in one cut wire). After cutting off the remaining length, the remaining length is less than the specified length and made unnecessary, and if all are judged to be inadequate length, they are cut off on the spot with the length less than the specified length and the remaining material It is paid out and discharged. For the same reason as described above, the remaining material dispensing section 81 has the same configuration and is arranged in two upper and lower tiers.

FIG. 6 is a perspective view showing the details of the configuration in which the wire drawing section 90 is enlarged.

As shown in FIG. 6, the wire drawing section 90 has a tunnel type guide 92 at the entrance of the drawing table 91.
And an air hand 94a with a parallel chuck driven by a rodless cylinder 93, and an air hand 94b with a parallel chuck driven by a high-speed feed AC servomotor 95.
A driven timing pulley 96 attached thereto, a driven timing pulley 97 having no driving source, and a timing belt 98 which is hung on the driven timing pulley 97 and transmits the power of the AC servomotor 95. Two shock absorbers (not shown) for reducing the shock at the time of stopping for high-speed feeding are provided at the limit positions at both ends.

Since the cutting position and the pull-out table 91 are apart from each other by a predetermined length, the air-driven rodless cylinder 93 is used to adjust the positional relationship in the longitudinal direction with the tension head of the label dislocation forming section described later. , And is configured to be transported by a predetermined length.

That is, the tip of the wire 11 that has passed through the tunnel guide 92 is connected to the parallel chuck air band 94.
b. Then, the element wire 11 is transferred in the direction of the transport unit by driving the AC servomotor. The transfer amount is controlled by counting the pulses of the encoder of the AC servomotor. When the wire 11 is transported to the cutting length, the rear end of the wire 11 passes through the tunnel type guide 92. At this time, the parallel chuck type air band 94b
The rear end is thereby gripped. Finally, both of the parallel chuck type air bands 94a and 94b are
Is transported to a predetermined position of the transport unit 101, that is, the same position as the tension head position of the label transfer molding unit described later.

In the wire drawing section 90 having such a structure, even if the wire 11 has a slight bend, the wire end passes through the tunnel guide 92 to reliably grip the tip portion with the air hand 94b with a parallel chuck and to a predetermined position. Can be pulled out to the position.

The AC servomotor of the wire drawing section 90 performs torque control so as to cooperate with the AC servomotor of the wire feeding section so that the wire 11 is always tensioned so as not to meander. .

For the same reason as described above, the wire drawing section 90 also has the function of automatically moving up and down to two upper and lower positions.

The wire drawer 90 is provided on the gantry 100 as a set of two air cylinders and guide rods 99 (not shown) as a lifting / lowering function in order to be able to draw a wire exceeding a predetermined length. It consists of 6 sets over the entire length.

On the other hand, the transport section 101 is connected to the wire drawing section 9.
The wire is transported from 0 to the label dislocation forming unit. The transport unit 101 has a hand 103 having a parallel chuck 102 having a high gripping force as shown in FIG. 7 and a wire 103 as shown in FIG. A hand 105 having an inclined chuck 104 that is hard to fall, and X, Y, and Z directions equipped with these (FIG. 1)
1) and one strand stand loader 107 for controlling the positioning of the two axes in the X and Z directions shown in FIG. 1.

In this case, four loaders are used in order to reliably handle the thin wire 11,
The parallel chuck 102 and the hand 103 are used for the two devices at both ends in the longitudinal direction.

In this configuration, the wire is transported so that the cutting section 70 side is always at the same position.
07, the X and Y axes are transferred, and a recess 108a is provided in the drawer table 91 corresponding to the gripping position.
The wire 11 can be securely held several mm above the lower end of the wire 02 so that the wire 11 does not drop from the parallel chuck 102.

Further, since the length of the wire may change,
The other end, which becomes an arbitrary position,
Is installed, and the parallel chuck 10 is set with the strand end floating.
2 and a loader 106 equipped with a hand 103 and securely gripping a few mm above the lower end of the parallel chuck 102 to prevent the longitudinal positions of the wires 11 from becoming irregular. This relates to the accuracy of the bending position in the label dislocation forming described later.

Further, two inclined chucks 10 are provided at the center.
By using the loader 106 equipped with the hand 4 and the hand 105, there is no gripping force, but by scooping up, the thin strand is reliably lifted at any place so that it does not drop even if it moves at high speed. .

As shown in FIG. 7, the loader 106 moves the element wire 11 into three axes: a Z axis for vertical movement, an X axis for forward and backward movement, and a Y axis for horizontal (longitudinal) movement. Is controlled.

In these hands 103 and 105, as shown in FIGS. 7 and 8, the Z-axis is equipped with a large-diameter timing pulley 112 on a rotary nut (not shown) of a ball screw 109 with a ball spline, and the timing belt 113 supplies power. It is designed to be transmitted and raised and lowered.
On the X-axis, a timing pulley (not shown) is sandwiched by an idler roller to an AC servomotor (not shown) serving as a power source on a fixed linear timing belt (not shown) to transmit power and move in the X-axis direction.

FIG. 9 is an enlarged perspective view showing the configuration of the label dislocation forming section.

In FIG. 9, the label dislocation forming section 120
Is provided with a mechanism for grasping one end of the wire 11 to remove slack, and also includes a single tension head 121 for controlling one-axis positioning in the longitudinal direction, and a mechanism for performing two types of bending on the wire 11. That is, one-axis positioning control in the Y direction 3
Like the tension head 121, the molding head 122, the tension head 121, and a tension head 123 having a mechanism for grasping one end of the strand 11 to take slack and having no Y-direction positioning control. ing.

The label dislocation forming section 12 having such a configuration
0, first, the tension heads 121 and 123
When the strand 11 is loaded by the loaders 106 and 107 (shown in FIG. 1), the strand 11 is moved to the standby position (the strand 11a in the drawing) as shown in FIG.
It is gripped by an arm 125 provided with a hard rubber provided in 24. At this time, since the strand 11a is slack because it is an elongated line of several millimeters square, it is necessary to remove the slack before forming in order to secure the positional accuracy of the label dislocation forming. For this reason, the strand 11 is moved to the position of the forming die while being held by the swing cylinder 124 provided in the laterally-moving guide air cylinder (not shown) (the strand 11 in the figure).
b). Then, after the wire 11 is clamped by the swing cylinder 127, the wire 11 is
b is released and pulled to both ends by the air slide table 128 to apply tension to the strand 11b.

Next, when the element wire 11 is loaded by the loaders 106 and 107 (shown in FIG. 1), the forming head 122 does not have the hard rubber provided in the swing cylinder 124 at the standby position as shown in FIG. The arm 126 performs positioning in the lateral direction, not gripping. The wire 11 is moved onto the forming die by a not-shown laterally-moving air cylinder with a guide, and the swing cylinder 124 is used to secure the position of the wire 11 in the horizontal direction until the tension heads 121 and 123 finish removing slack. And the arm 126 is held.

Forming Head 122 and Tension Head 1
When the strand 11 moves to the position of the molding die, the clamps 21 and 123 are clamped by the air cylinder 129 with a guide, and are rotated 90 ° in that state. The 90 ° rotation is performed by rotating the rotary plate 130 provided on the guide air cylinder 129 and the associated arcuate segment gear 132 through the fan-shaped gear 134 and the pinion gear 135.
The power is supplied by a rack 136 provided in 9. FIG. 12 shows a state of the molding head 122 rotated by 90 °.

The guide 131 for supporting the outer diameter and the surface of the rotary plate 130 is partially cut off from the necessity of having the air cylinder 129 with a guide for clamping the wire 11. For this reason, a guide 133 on the inner diameter side is provided separately. The guide 133 on the inner diameter side is formed using the inner periphery of the segment gear 132 having a bow shape as a sliding portion.

Thereafter, the forming head 122 performs three-dimensionally bending label dislocation forming using four types of forming dies provided on the upper and lower rotating plates 140a and 140b.
This three-dimensional bending includes two types of edgewise bending dies and two types of flatwise bending dies. Two types of molds are required for the following reasons.

In the label dislocation forming section, the stator coil is composed of dozens of strands in two rows, an upper row and a lower row. Even if the upper row is manufactured and combined, it is formed as one stator coil. Either long or heavy rows with poor handling need to be flipped 180 ° before combining. So 180 °
In order to form a group of label displaced wires in such a manner that one row is automatically reversed with respect to one row even without inversion, the required number of upper and lower four sets of label transposition molds are designated as No. 1.
No. 1 head to No. 1 It is held in four heads, and is automatically reversed by a program created in advance so that label dislocation molding can be performed sequentially.

The vertical opening and closing of the mold is performed by a vertical trapezoidal screw 138 having left and right screws, and both ends are supported by bearings 139 for high load. The molding die is a rotary plate 14 attached to the molding die provided on the internal thread of the trapezoidal screw 138.
When the trapezoidal screw 138 is provided with a rotational driving force by an AC servomotor (not shown), the upper and lower molding dies are closed to perform molding. In this case, a thread groove is formed in the trapezoidal screw 138 in the opposite direction so that the rotating plates 140a and 140b move toward or away from each other.

In the label dislocation molding, the AC servomotor is torque-controlled, the motor output torque is converted into a molding force, the value of which is set, and when this set value is reached, it is determined that the molding is completed and the automatic operation is performed. .

As shown in FIG. 12, the forming die 122 used first in the label dislocation forming includes rotary plates 141a and 141b for upper row of edgewise bending (bending in the short side direction of the wire 11). Is provided. Each edgewise mold has a corrugated groove for forming the wire 11, and plating and buffing are performed on the portion to reduce damage to the wire 11. ing.

As shown in FIG. 13, a flatwise forming die 122 used second is an upper die 14 for flat row bending (bending in the long side direction of the wire 11).
2a and a lower mold 142b are provided, and each flatwise mold has an uneven shape for forming the element wire 11, and a plating process and a buff polishing are performed on the portion thereof, and the element wire is formed. Care has been taken to reduce damage to 11. Therefore, before forming with the mold, the strand 11 is rotated 90 ° in advance to return to the original state.

When performing the label dislocation molding of the wire 11, only two sets of the four dies are used. The indexing table 143 mounted on the upper part of the molding head has a function of indexing the molding dies, not shown. It consists of a shaft coupling, a spline shaft, large and small timing pulleys, a timing belt, and a bearing that supports the spline shaft.

At the time of indexing, the indexing table 143
The power of 180 ° rotation is transmitted to the spline shaft via the shaft coupling, and from the small-diameter timing pulley provided on the spline shaft to the large-diameter timing pulley having twice the teeth of the small-diameter timing pulley via the timing belt. The power is transmitted to reduce the speed, and 180 ° is reduced to 90.
A predetermined index is determined by the rotation of °.

When the strand is label-transformed, the three forming heads automatically move to the label-transfer forming section of the next strand based on the stator coil data input to the operation panel (not shown). The three forming heads are mounted on the same gantry on which the linear motion guide 144 is disposed, and can be moved by driving a linear belt (not shown), a timing pulley, and an AC servomotor.

In order to arrange the wires 11 formed by label transposition on the conveyor, as shown in FIG. 1, a loader 10 which conveys the wires 11 from the wire drawing section 90 to the label transposition forming mechanism is used.
6,107, strand stand 161, and conveyor 162
It is done in.

The loaders 106 and 107 are controlled by adding position data up to the label transposition forming mechanism to each hand constituting the transport section 101 (shown in FIG. 6). When the wire 11 is subjected to label dislocation molding, the loaders 106 and 107
Based on interference data input to an operation panel (not shown) in advance so as not to interfere with the three forming heads 122 (shown in FIG. 9) linearly moving in the y-axis direction,
It is programmed to move to a position that keeps a certain distance from 2.

Further, in order to arrange the formed wires 11b on the conveyor 162 shown in FIG. 1 and to arrange them at equal intervals, the wires 11b must have an interval which does not intersect with a groove in which the wires 11b can be placed vertically. Wire stand 161 is provided. The wire 11b has a rectangular cross section of several mm square and is easy to bend and bend. Therefore, when the wire 11b is twisted after being placed on the wire stand 161, the wires 11b are surely taken one by one and easily placed. The stands 161 are placed in two rows.

Means for transporting the label-transformed-formed strands 11b arranged on the transport conveyor 162 to the place where they are to be twisted are a long transport belt 163, a table supporting the transport belt 163, and a tension device for the transport belt 163. And an AC motor with a speed reducer (not shown) serving as a drive source for moving the transport belt 163.

In the automatic operation, when the number of strands cut and formed by the number input to the operation panel (not shown) is arranged on the table, the operation is automatically stopped, and these strands are moved to the next twisting station. Unless completed, automatic operation is set not to restart.

In order to twist a label-transformed wire,

A loader 151 (shown in FIG. 1) for controlling two-axis positioning in the Y direction and a loader 151 for controlling two-axis positioning in the X and Z directions including a separating hand 156 for gripping an end portion for twisting a wire.
(Shown in FIG. 1).

The clamp hand 154 has one end of the wire 11
When the wire is lifted to twist the wire b (see FIG. 14), a tensile force acts in the longitudinal direction.
Air chuck 160 that holds the air chuck 1b without shifting, and a chuck driving mechanism 1 that applies a holding force to the air chuck 160
60b, and a driving mechanism 160d for moving the air chuck 160 and the chuck driving mechanism 160b in the Z direction using the shaft 160c as a guide.

As shown in FIG. 16, the separating hand 155 has three mechanisms for holding the group of strands, and a mechanism for opening and twisting the twisted strands, in order to facilitate twisting of the label dislocation portion. A mechanism is provided to prevent the wires from spreading. That is,
The mechanism for holding the strand group includes an air cylinder 171 for pushing the fixed end side of the strand group from above during normal twisting, and an air cylinder for pushing the fixed end side of the strand group from above during reverse twisting. An air cylinder 182 for sandwiching the width direction (X axis) of the cylinder 181 and the wire group from the lateral direction is provided.

As a mechanism for preventing the wire from opening or spreading, an air cylinder 174 for inserting and removing the rod 173 between the wires in the Z-axis direction, and a rod 173 from the inside of the wire to the outside (X-axis). Air cylinder 175 for pushing in the X direction, and the air cylinder 17 for moving the twisted strand group in the X-axis direction.
8. Guided air cylinder 180 for inserting and removing skewers 179 between the separated strand and the twisted strand, and a rodless cylinder for moving this guided air cylinder 180 to the vicinity of the twisted position of the strand 176 is provided.

Further, the separating hand 156 has the same configuration as that of FIG. 7, and the description thereof is omitted here.

On the other hand, the loader for controlling the positioning of the clamp hand 154 and the separating hands 155 and 156 has the following functions.

In FIG. 1, a one-axis positioning control loader 153 in the Y direction is operated by a belt driving device for the purpose of maintenance-free operation and high-speed movement. In this belt driving device, both ends of a belt (not shown) are fixed to a tension mechanism, and an AC servo as a driving source and a speed reducer are arranged.
The output shaft of this reduction gear is equipped with a timing pulley. In this case, since the movement stroke of the belt is long, 2
The belt is prevented from falling off by being sandwiched between the individual idling rollers with brims, and power transmission is ensured.

The loader 152 for controlling the biaxial positioning in the X and Y directions includes the X-axis drive in addition to the driving of the loader 153 in the Y direction.
Driving in the direction is operated by a similar belt driving device. In this case, since the X axis moving in the Y direction has a large aspect ratio,
Timing pulleys are provided at both ends of an output shaft extended from a Y-axis speed reducer (not shown) to ensure accurate parallel movement as double drive.

In the label dislocation forming section having such a configuration, the air chuck 1 of the clamp hand 154 shown in FIG.
With the wire group held at 60, the clamp hand 15
In the case of forward twisting in which the twisting proceeds in the direction of No. 4, first, the fixed end side of the group of strands is separated at a position away from the twisting position and pressed from above by the air cylinder 171 of the hand 155.

In this state, the strand 1 is
After lifting the vicinity of the other end of 1 and moving it in the X-axis direction, it is lowered (Z-axis) to a position where it does not interfere with the strand stand 161. At this time, the rod 173 of the separating hand 155 in FIG.
Is lowered from above (Z axis) by the air cylinder 174,
Further, the rod 174 is pressed from the inside of the strand to the outside (in the X-axis direction) by the air cylinder 175 that moves in the X-axis. As a result, the amount of movement of the X axis locally increases, twisting can be performed efficiently, and the wire does not bend where it is unnecessary.

In this state, another rod (not shown) is lowered (Z-axis) from above by the air cylinder 177, and the X-axis moving air cylinder 17 is brought into contact with the end face of the already twisted strand group.
At 8 pull the stick. The reason for this is that if many strands are twisted, a gap is created between the strands, and the strands are spread by springback at the transition part of the strands. This is because a reliable twisting cannot be performed unless they are placed so that they do not overlap each other.

The above-described wire separation is performed when the wire thickness is small. However, when the wire thickness is large, the wire cannot be separated. Skewers 179 between the stranded wire and the guided air cylinder 1
By inserting the rod 80 from above (Z axis) and running the rodless cylinder 176 to the vicinity of the twisting position, it is possible to cope with a wire having any thickness.

When the group of strands is handled in this way,
Even if the amount of movement in the X direction is small, the label dislocation portion can be twisted reliably.

Next, a description will be given of a case of reverse twisting in which twisting is performed in the direction of the hand 156 which grips the strands formed by label dislocation one by one.

As shown in FIG. 17, while the wire group is held by the air chuck 160 of the clamp hand 154 of FIG. 15, the wire group is released by the air cylinder 181 of the releasing hand 155 at a position close to the twisting point. While being pressed from above the fixed end side, the air cylinder 182 sandwiches the width direction (X axis) from the side.

In this case, when pressing from above, a material with a soft waist is stuck on the contact surface in order to press the step surface, so that the wires do not float more than necessary even on the surface with a low step. Twisting can be performed.

In this state, the strand 1 is
After lifting 1 and moving it in the X-axis direction, it is lowered (Z-axis) to a position where it does not interfere with the strand stand 161. At this time, the rod 173 of the separating hand 155 in FIG. 16 is lowered from above (Z axis) by the air cylinder 174, and the rod 174 is moved from the inside of the element wire to the outside (X axis) by the air cylinder 175 moving in the X axis. Direction). As a result, the amount of movement of the X axis locally increases, twisting can be performed efficiently, and the wire can be prevented from being bent at unnecessary places.

In this state, another rod (not shown) is lowered from above by the air cylinder 177 (Z-axis), and the X-axis moving air cylinder 17 is brought into contact with the end face of the already twisted strand group.
At 8 pull the stick. The reason for this is that if many strands are twisted, a gap is created between the strands, and the strands 1
This is because the wire group is expanded by the springback caused by the first transfer portion, so that when the next wire to be twisted is placed on the lower table, the wires cannot be reliably twisted unless they are overlapped.

By combining the upper row conductor of the coil obtained by forward-twisting the wire group formed by the label transposition and the lower row conductor of the coil obtained by reverse-twisting, one stator coil can be obtained. Label dislocation conductors can be manufactured.

Next, a method of manufacturing a label dislocation conductor according to the present invention will be described.

FIGS. 18 and 19 are flow charts for explaining the procedure for manufacturing a label dislocation conductor according to the present invention.

The wires used for the label dislocation conductors need to be insulated between the wires in order to finally form a coil. For this reason, it is necessary to coat the wire with an insulating material in advance. For example, a fibrous insulating material is wound around a rectangular copper wire of several mm square, and this is used as the wire (step 1). Such a wire is wound on a drum having a relatively large diameter without causing twisting or the like in the wire and making it easy to handle a long wire (step 2). Then, the drum configured as described above is attached to, for example, the above-described label dislocation conductor manufacturing apparatus (step 3).

The strand wound on the drum is guided from the drum to the apparatus by a conveying means using, for example, a belt. After the drum is set in the apparatus, the drum is pulled out to the sending means manually, and thereafter, it is automatically drawn out (step 4).

On the other hand, the size of the strand is several millimeters at most, so that it is easy to bend. Therefore, there is provided a step (step 5) of applying a certain amount of tension to the strand when the strand is pulled out from the drum to prevent the drawn strand from becoming loose.

Next, it is determined whether or not there is a “join” between the wires in the conductor used as the label transition conductor. "Connecting" is the connection between the last end of a strand wound on one drum and the leading end of the strand wound on the next drum, producing a large label transposition conductor It is a part that can always be made when using a large amount of strands, but it becomes physically thicker when it is twisted into a label transition conductor due to deterioration of insulation performance,
Its performance is greatly reduced. Therefore, if there is a “splice”, information that “there is a splice several meters before the cutting step” is transmitted to a cutting step described below. Then, the information is used to control the length of cutting, so that the "joining" portion does not enter the label dislocation conductor (step 6). Note that the wires themselves flow to the next step even if there is a “connection”.

On the other hand, the wire immediately after being drawn has a winding habit when wound on a drum, and is inconvenient to use as a linear label dislocation conductor. for that reason,
In order to remove a distortion such as a winding habit remaining in the strand, the strand is passed through the step of removing distortion (step 7) to prevent deterioration of the label dislocation conductor performance.

The strand is finally twisted as a label transposition conductor. At this time, since the end portion is electrically connected to another label transposition conductor, the insulating coating is removed from the stage of the strand. (Step 8). Therefore, the wires are passed through the step of heating the coated portion (step 9) so that the insulating coating can be easily removed.

Thereafter, the insulating coating is removed from the heated portion with a brush or the like (step 10).

Furthermore, since a large current flows through the label dislocation conductor, leaving dust such as the remaining coating material on the portion from which the insulating coating has been removed may cause the dust to seize. In some cases, the performance of the conductor is degraded. For this reason, a step of cleaning the portion from which the insulating coating has been removed (step 11) and preventing performance degradation is provided.
The portion where the coating needs to be removed is a part of the long wire, and the other region does not need to be. Therefore, the portions that do not require the removal of the coating are subjected to these steps (step 8).
It is not necessary to go through step 11).

Since the label dislocation conductor is formed from a plurality of strands having a predetermined length, it is necessary to cut the strand drawn from the drum into a plurality of strands having a predetermined length. For this reason, if it is determined that the "joint" portion comes within the predetermined length to be cut in the strand already drawn out from the drum to some extent (step 13), Dispense the wire as waste (Step 1)
4, step 15). Then, the wire is drawn again (step 12), and the position of the “joining” portion is determined. When it is determined that there is no “joining” in the strand of a predetermined length to be cut, the strand is cut to a predetermined length as a strand for a label dislocation conductor (step 16).

The strand having a predetermined length is conveyed to the dislocation forming means for performing label transposition (step 1).
7).

Then, after the label dislocation is processed at a predetermined position (step 18), the process is shifted to a step of twisting as a label dislocation conductor (step 19). Since label dislocation has already been processed on the strand, a label dislocation conductor is completed by twisting a plurality of strands.

[0126]

As described above, according to the present invention, the label dislocation pitch can be shortened by subjecting the strands to label dislocation molding one by one, and the insulator can be inserted by providing a gap in the label dislocation portion. It is possible to provide an apparatus and a method for manufacturing a label dislocation conductor for a stator coil, which can manufacture a stator coil that does not cause a short circuit even without it.
