Abstract

PROBLEM TO BE SOLVED: To provide a winder for a stationary electromagnetic induction device, of which an installation space is reduced and which can improve reliability without to possibility of damaging a wire rod. SOLUTION: A supply drum 20 is raised and lowered by a lifter 41, and also a hoist 81 is lifted by a hoist lifter 71, and even if the position of a wire rod W drawn from the supply drum 20 is changed vertically, it is made so that it is hoisted substantially horizontally by the hoist 81. At hoisting on the host 81 and when the wire rod is required to be hoisted back on the supply drum 20, a torque imparting the supply drum 20 is controlled by a powder clutch 55 to set a hoist and hoist-back tension to be a specified value. Since the wire rod W between the supply drum 20 and a hoist core 81 becomes substantially horizontal, and a bending way is not produced, it is possible to reduce the installation space by shortening the distance between the supply drum and the hoist. Furthermore, since the supply drum is controlled to impart a specified drawing tension to the wire rod, there is also no possibility of damaging the wire rod.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a winding device used for manufacturing a static electromagnetic induction device such as a transformer.

[0002]

2. Description of the Related Art FIG.
It is a side view which shows the conventional winding apparatus of the transformer shown by patent publication 18. In the figure, a base 11 is installed on a floor F of a factory, and a circular turntable 12 is placed on the base 11.
Are supported rotatably about a vertical axis. On the upper surface of the turntable 12, a cylindrical winding form 13 is concentrically fixed. Gear 1 on the lower surface of the turntable 12
4 is provided concentrically and the motor 1 installed on the base 11
The pinion 16 driven by the gear 5 is engaged.

A lifting device 18 is provided on the floor F so as to surround the former 13. The elevating device 18 supports a supply drum 20 rotatable about a vertical axis on an elevating table 19 that is elevated by a pantograph mechanism in a vertical direction indicated by an arrow A while maintaining a horizontal position. A brake 21 is provided between the supply drum 20 and the former 13 to apply tension to the wire W wound on the former 13.

[0004] The winding die 13 is rotated by the motor 15 via the turntable 12 to take up the wire W wound around the supply drum 20 to form a cylindrical winding 25. At this time, in synchronization with the rotation of the winding form 13, the control unit (not shown) controls the lifting and lowering of the lift table 19 to control the brake 21.
And the wire W wound around the winding form 13 is kept substantially horizontal.

[0005]

Since the conventional winding device is configured as described above, there are the following problems. (1) Since both the supply drum 20 and the brake 21 are fixed at a constant height on the elevator 19, when the wire W is wound from the supply drum 20, the wire W The pass line bends. For example, the WB shown by the dashed-dotted line in FIG. To prevent this, the distance between the supply drum 20 and the brake 21 must be increased, but in this case, the installation space for the winding device is increased. (2) Since the frictional force is applied to the wire W by the brake 21, there is a possibility that the wire, particularly the wire insulated by the paper tape winding, may be damaged.

(3) Since there is no device for applying tension to the wire when rewinding the wire to the supply drum 20, the winding mold 13
When rewinding the wire W wound on the supply drum 20, the wire may be loosened, and the wire may be deformed or entangled. (4) In a winding in which the wire W is wound a plurality of times so as to overlap in the radial direction of the winding form 13 to sequentially form a disc-shaped section coil, one section coil is switched to the next section coil. When crossing, crossover bending (hereinafter referred to as "S-bending") is performed to process the wire W in a stepped manner only by the crossover, but there is no suitable device for performing this, and the work efficiency is poor because it is performed manually. Was. (5) There is no suitable transposition device that transposes the wire drawn from the plurality of supply drums 20 and supplies it to the winding form 13.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and to provide a winding device for a static induction machine which can reduce the installation space, does not damage the wire, and can improve the reliability. Aim. Furthermore, when crossing from one section coil to another section coil, it is possible to perform a crossover bending process in which the wire material is processed stepwise by the crossover margin, or to transpose a wire material drawn from a plurality of supply drums. It is an object of the present invention to provide a winding device for a static electromagnetic induction device that can supply the windings with their mutual positions interchanged, thereby improving the working efficiency and producing a winding of stable quality.

[0008]

In order to achieve the above object, a winding device for a stationary electromagnetic induction electric machine according to the present invention comprises a supply drum wound with a wire rotatable in both forward and reverse directions about a vertical axis. The brake device that brakes the rotation of the supply drum so as to apply a predetermined winding tension to the turntable on which the supply drum is placed and the wire drawn from the supply drum And a winding machine having a winding form for winding a wire from the supply drum to form a winding while rotating about a vertical axis. And a drum for raising and lowering the supply drum so that the wire wound on the former from the supply drum is substantially horizontal between the supply drum and the former. Those having at least one of the former lifting device for lifting the descending device and former. Since the wire wound from the supply drum to the former is almost horizontal between the supply drum and the former, no bending habit occurs even if the distance between the supply drum and the former is shortened. Space can be reduced. Further, since a predetermined winding tension is applied to the wire drawn out of the supply drum by the braking device, there is no possibility of damaging the wire, particularly a wire insulated by paper tape. Furthermore, since the wire once sent out is rewound while applying a predetermined unwinding tension, the wire is not sagged or deformed during the unwinding, and it is possible to prevent the wire from being disordered when the wire is wound again.

[0009] Then, the winding form is formed by winding the wire in the radial direction of the winding form and winding, so that the one rod-shaped coil section and the one coil section allow the wire to pass over and into the one coil section. The winding is formed by winding so as to form another disk-shaped coil section which is formed by adjacently overlapping and winding in the radial direction of a winding form. Provide a pre-processing device for performing bending for crossover so that the wire can pass from one coil section to another adjacent coil section, and provide both a drum lifting device and a winding die lifting device, or a drum lifting device A pre-processing device elevating means for elevating and lowering at least one of the device and the winding elevating device, and a pre-processing device elevating means for raising and lowering the pre-processing device, and supplying a wire that is passed through the pre-processing device from the supply drum and wound into a form to the supply drum. Characterized in that as can be substantially horizontal between the former. The pre-processing device allows the machine to perform a transition bending process from one coil section to another adjacent coil section.

Further, the pre-processing device once forms a disk-shaped coil section to determine a position on the wire where the crossover bending portion is to be provided, and then uses a rewinding device to position the wire on the rewind wire by a predetermined length. It is characterized in that it can be subjected to a bending process. Since the wire is unwound at a predetermined unwinding tension, the wire does not sag or deform at the time of unwinding, and there is no possibility that the position of the migrating bent portion is shifted when the wire is bent and wound again.

[0011] The braking device may further include a turntable that applies a braking torque obtained from a predetermined winding tension to be applied to the wire when winding the wire from the supply drum and a winding diameter of the wire wound around the supply drum. To control the winding tension to a predetermined value. Since the winding tension is set to a predetermined value by applying a braking torque to the turntable, there is no possibility of damaging the wire.

The rewinding device turns the rewind torque determined from a predetermined rewind tension to be applied to the wire when rewinding the wire to the supply drum and a winding diameter of the wire wound on the supply drum. To control the unwinding tension to a predetermined value. Because it rewinds with a predetermined rewind tension,
The wire does not sag or deform during unwinding, and there is no possibility that the position of the cross-over bending portion will shift when the cross-over bending process is performed and re-wound.

[0013] Further, the supply device has a plurality of turntables, and the pre-processing device is adapted to take up each wire from the supply drum placed on each turntable into a preform. In order to perform a transposition in which the mutual positions in the radial direction are exchanged, a guide device is provided for exchanging and guiding the positions in a direction perpendicular to the winding direction of the wire. Wires from a plurality of supply drums can be transposed by exchanging their mutual positions in a direction perpendicular to the winding direction of the wire.

The wires W1 and W2 are respectively drawn out, pass through the horizontal position detecting device 61, further pass through the pre-processing device 100, and are moved by the vertical guide rollers 127 to the two.
While the books are put together and wound on a winding form 81 of a winding machine 70, a winding 25 having a predetermined shape is manufactured.

Next, the operation will be described. First, the operation of the supply device 40 will be described with reference to FIGS. The supply drum 20 is mounted and fixed on the turntable 54,

00 almost horizontally so as to be wound on the former 81 in the direction of arrow R in FIG.

As the wire W is pulled out from the supply drum 20, the position where the wire W is pulled out on the supply drum 20 changes vertically as shown in FIG. 6 or FIG.
In other words, the pass line of the wire W fluctuates in the vertical direction,
A pair of upper and lower sensors 64 move up and down following the wire W.

When the position of the wire W to be drawn is below the shaft 62, the sensor 64 is pulled downward and the rotating arm 63 rotates counterclockwise about the shaft 62 in FIG. The sensor 66 turns on. When the sensor 66 operates, the elevator 44 is moved by the elevator motor 45.
Is driven in the ascending direction as indicated by the arrow J in FIG. 6, and the wire W is in a substantially horizontal position. As a result, the sensor 66 is turned off, and the sensor 6 is turned off.
5 is turned on, and the lift of the lift 44 is stopped.

Conversely, as shown in FIG. 7, when the position where the wire W is pulled out is higher than the shaft 62, the rotary arm 63 is rotated clockwise, and the sensor 67 opposed thereto is turned on. The elevator 44 moves down in the direction of arrow K by operating. Then, when the posture of the wire W returns to a substantially horizontal position, the sensor 67 is turned off, the sensor 65 is turned on, and the descent of the elevator 44 is stopped. As described above, the lifting / lowering device 41 raises / lowers the lifting / lowering table 44 following the change in the position of the wire W pulled out from the supply drum 20, and maintains the pass line of the wire W substantially horizontal.

The turntable 54 is connected to a rotary drive motor 56 via a powder clutch 55.
The rotation drive motor 56 applies a torque in the opposite direction to the drawing of the wire W from the supply drum 20, that is, a torque in the rewinding direction, to the supply drum 20, and applies a back tension which is a predetermined winding tension to the drawn wire W. . Therefore, unlike the conventional device, the brake 21 in FIG. 13 is unnecessary.

The magnitude of the back tension to be given at this time is controlled as follows. First, the roller 59 is brought into contact with the outer periphery of the wire W wound around the supply drum 20, and the rotational displacement of the actuator 57 is detected by the rotational displacement detector 60, and the outer periphery of the wire W wound around the supply drum 20 is detected. Find the diameter. The winding torque to be applied to the supply drum 20 is determined based on the outer diameter and the back tension to be applied, and the transmission torque of the powder clutch 55 is controlled so as to apply the winding torque.

When the wire W once sent out from the supply drum 20 needs to be rewound to the supply drum 20 for some reason, the turntable is applied while applying a predetermined unwinding tension to the wire W as follows. Rotate 54 in reverse. That is, the unwinding torque to be applied to the supply drum 20 is calculated from the winding diameter of the wire W of the supply drum 20 detected by the rotational displacement detector 60 and a predetermined unwinding tension, and the powder clutch is applied so as to apply this torque. 55 is controlled. At this time, the winding driving device 78
Controls the reverse rotation speed of the former 81.

The wires W1 and W2 drawn from the supply drum 20 pass through the pre-processing device 100 almost horizontally, and
The book is collectively wound around a winding die 81. This will be further described with reference to FIGS. FIG. 9 shows a wire W
Shows a state in which the winding 25 is formed while winding
FIG. 10 is a partial cross-sectional view showing the right half of the center line S of the winding die 81, and FIG.
It is an expanded sectional view in I-XI.

The winding 25 is formed by successively forming a plurality of disc-shaped section coils 25a one after another. For example, the lowermost section coil 25a has a wire W1 on the outside and a wire W2 on the inside. (See FIG. 1) 2
The wire rods W1 and W2 obtained by grouping the books are wound on the former 81 a plurality of times so as to overlap in the radial direction of the former to form a disc-shaped section coil 25a.

Subsequently, a second-stage section coil 25a is formed, but without cutting the wire W, the wires W1, W2
Must be wound from the outside to the inside. For this reason, as is well known, the section coil 25a of the second stage from the bottom tentatively winds the section coil in a disk shape from the inside to the outside on the former 81, and unwinds the section coil to reverse the inside and outside. To form a section coil 25a in a shape of being wound from the outside toward the inside. Hereinafter, in the same manner, a predetermined number of section coils 25a wound in a direction from the inside to the outside and from the outside to the inside are formed.

For winding the section coil 25a, the wire rods W1 and W2 drawn from the supply drum 20 are joined together by the vertical guide roller 127 of the pre-processing device 100, and then wound around the winding die 81. The winding die 81 includes a rotary table 79.
The disk-shaped section coil 25a is formed by rotating the rotary table 79 by the servomotor 80. At this time, the torque applied to the supply drum 20 via the turntable 54 by the powder clutch 55 is controlled so that the tension of the wire W wound around the winding form 81 becomes constant.

When the section coil 25a has been wound up by one section, the lifting motor 7
The lifting platform 77 is lowered by a predetermined size in a step-like manner via 4 to wind the next section. The positioning of the descent is performed by detecting the height of the rotary table 79 by the encoder 75. Thereby, the pass line of the wire W pulled out from the supply drum 20 and wound around the winding die 81 is maintained substantially horizontal.
Therefore, the height of the work position where the section coil 25a is formed on the former 81 is controlled to be the same as the height of the worktable set to facilitate the work.

At this time, in order for the wire W to pass from one section coil 25a to the adjacent section coil 25a, on the outermost and innermost sides of the section coil 25a, the outer section section 25b and the inner section section 25c are provided. Is formed. This is the pre-processing device 100
The details will be described later. As shown in FIG. 9, a plurality of short fence-shaped spacers 25d are radially inserted between the section coils 25a at predetermined positions on the circumference thereof.

Further, the winding 25 is provided with a crossover section 25b outside the section and a crossover section 2 inside the section to suppress the circulating current.
In 5c, so-called transposition is performed in which two wires are exchanged between the inner diameter side and the outer diameter side. In the past, dislocations were done by hand tools using a pattern etc. for each section coil, marking the processing position on the circumference of the winding together with the S bending process, but this dislocation was pre-processed. This can be performed by the device 100. This will be described later in detail.

In this embodiment, the S-bending point pre-processed as follows is a predetermined angular position α on the winding.
(FIG. 9). That is, the winding tension of the wire W wound from the supply drum 20 to the winding die 81 is controlled to a predetermined value by the powder clutch 55. Further, since the positional relationship between the winding machine 70 and the pre-processing device 100 is constant, the servo motor 81 controls the rotary table 79 to determine the angle. That is,
The control is performed so that the specified angle α and the rotation speed N of the turntable 79 become a predetermined value, and it is possible to guide the S bending point to be exactly at a predetermined position on the winding.

Returning to FIG. 3 and FIG. 4, the S bending, which is the pre-processing of the wire W by the pre-processing apparatus, will be described. The wires W1 and W2 drawn from the supply drum 20 are
2 (FIG. 1) is maintained in a substantially horizontal posture by the horizontal roller 103 adjusted to the same height as that of FIG. In addition, the wires W1, W
The position of 2 on the horizontal plane is regulated by vertical rollers 104 and 105 provided before and after the S bending device 111, respectively.

The lower limit of the vertical direction of each of the wire rods W1 and W2 exiting the vertical roller 105 is restricted by the horizontal guide roller 123, and the upper limit is restricted by the vertical guide roller 127. Further, in the horizontal plane, they are gathered together in a form squeezed by the vertical guide roller 127, and wound up by the winding die 81. The wires W1 and W2 are usually supported by the horizontal guide rollers 123, and the wires W1 and W2 drawn from the supply drum 20 are supported by the horizontal rollers 103 and the horizontal guide rollers 123, and are wound substantially horizontally. It is wound by 81.

When one section coil 25a is formed, the adjacent section coil 25a is wound, so that when the wire W is wound up, it is placed at a predetermined angular position on the circumference of the winding when the wire W is wound, and the section crossover section 25b and the inside of the section are wound. Crossover 25c
(See FIGS. 10 and 11) to perform S bending. Based on the current rotational position of the turntable 79, the position where the S bending point should be provided in the front wide is determined.

The positions of the wires W1 and W2 in the vertical direction are regulated by the rotational displacement detector 60, the horizontal roller 103 and the horizontal guide roller 123, and the positions in the horizontal direction are determined by the vertical rollers 104 and
105, on a pass line regulated by the vertical guide roller 127; At the time of S-bending, the frame 114 is driven by the drive cylinder 113 on the traversing guide 112 in the vertical direction of FIG. 3, that is, in the horizontal direction of FIG. 5, from the retracted position to the processing position, that is, the pass lines of the wires W1 and W2. Move up. FIG. 5 shows that the right frame 114 is a wire W1.
, The left frame 114 is in the retracted position at the S bending position.

At this time, the two rotating rollers 117 attached to the bending shaft 116 are located at positions vertically overlapping each other as shown in FIG. 8, and have a sufficient distance from the wires W1 and W2. . The frame 114 is moved to a predetermined position, that is, to the pass line, and the wires W1 and W2 are sandwiched between the rotating rollers 117 provided on the respective bending shafts 116.
The bending shaft 116 is moved by the swing actuator 118 in FIG.
Is rotated in the counterclockwise direction.

Then, as shown in FIG. 4, the wire W1 or the wire W2 is fixed between the left fixed roller 115 and the left rotating roller 117 and between the right rotating roller 117 and the right fixed roller 117. Plastically deformed between the side rollers 115,
An outer section crossover section 25b or an inner section crossover section 25c having a predetermined step in the vertical direction is formed. Thereafter, the bending shaft 116 is returned counterclockwise by the swing actuator 118 so that the rotation-side roller 117 is separated from the wire W as shown in FIG. 8, and then the frame 114 is moved backward to the retracted position by the drive cylinder 113. .
By performing such an operation, the S-bending process is completed.

Next, the operation of the wire rod level adjusting device 121 will be described. As shown in FIG. 9, the wire rods W1 and W2 are joined together by a vertical guide roller 127 to form a single unit.
Wound around one. The wire W1 is formed by the vertical guide roller 127.
This is because the advantage of the horizontal guide roller 123 that regulates the height in the horizontal direction is better when the W2 is combined into one.

The wire W passing through the S bending device 111
1 and W2 are the horizontal rollers 10
3, the height is regulated by the horizontal guide roller 123, and the arm end roller 126, and the sheet passes horizontally. Also,
When the crossover section 25b and the crossover section 25c that have been subjected to the S-bending process pass, the arm end roller 126 is moved upward by the lifting cylinder 124 as shown in FIG.

As described above, the wire rods W1 and W2 are crossed from one section coil to the next section coil, that is, after the S-bending process is performed at the beginning or end of winding of the section coil. When performing transposition in which the inner diameter side and the outer diameter side of the winding form are switched, the positions of the wire W1 and the wire W2 on the horizontal plane must be switched as shown in FIG. Left side) horizontal roller 103
Is increased so that the wire W2 intersects above the wire W1.

In the present invention, even when the wire W1 and the wire W2 intersect in the vertical direction due to such dislocation and the pass line is slightly inclined, the wire W1 and the wire W2 pass through the pre-processing device from the supply drum. It describes that the wire wound on the winding form is substantially horizontal between the supply drum and the winding form.

In order to switch the wire rods W1 and W2, the wire rods W1 and W2 are removed from the vertical rollers 104 and 105 and the vertical guide roller 127, and the upper and lower positions of the wire rods W1 and W2 in FIG. , 105 and the vertical guide roller 127 to obtain the state shown in FIG. In addition,
Cylinder 102, horizontal roller 103, vertical roller 104,
The wire rod 105 and the wire rod level adjusting device 121 constitute a guide device in the present invention.

The supply device 40 and the winding machine 7 as described above.
By combining with 0, the winding of the wire W or the rewinding to the supply drum 20 can be performed while keeping the pass lines of the wires W1 and W2 substantially constant and applying a predetermined tension. In addition, the rotation drive motor 56 is stopped with the brake applied, and the powder clutch 55 is stopped.
, The braking force can be applied to the supply drum 20 to adjust the back tension when the wire W is wound around the winding die 81.

Instead of applying a braking force with the powder clutch 55, for example, a brake for directly braking the main shaft 52 may be provided, or a flange or the like of the supply drum 20 placed on the turntable 54 may be directly braked. It may be something. Similarly, the flange portion of the supply drum 20 may be directly driven in the method of applying the rewind tension. In addition,
A drum lifting device may be provided on the turntable 54 to raise and lower the supply drum.

As described above, the winding is formed by winding the wire W around the winding form 81 while keeping the pass line of the wire W substantially horizontal. 25a can be formed. Heretofore, the section coil 25a was wound while finely adjusting the wires W1 and W2 so as to overlap on concentric circles using their own hands as a guide at a place corresponding to the wire rod level adjusting device 121.

Even if the distance between the supply drum 20 and the former 81 is reduced, no bending habit is formed, so that the installation space can be reduced. Furthermore, since a winding torque is generated by applying a braking torque to the supply drum 20, the wire rod,
In particular, there is no risk of damaging the paper winding material around which the paper insulating tape is wound. In addition, since the rewinding is performed while applying a predetermined unwinding tension, the wire does not bend and deform at the time of rewinding, and the position of the wire does not shift when rewinding.

With the S bending device 111, when the wire is crossed from one section coil to the next section coil, it is possible to perform a cross-bending process in which the wire is formed in a stepped manner by the crossing margin. Also, the horizontal roller 10 of the S bending device 111
By changing the height of 3, the wire drawn from a plurality of supply drums can be supplied to the former 81 with their mutual positions interchanged for transposition.

Further, in the S-bending device 111, the bending shaft 116 is made a double shaft, and the rotating roller 1 is attached to the inner shaft.
By mounting a roller corresponding to the fixed-side roller 115 on the outer shaft and adjusting the rotation angle of these double shafts, it is possible to arbitrarily select a dimension for making a step in the S-bending process. It is also possible.

Since the determination of the position of the S-bending point is made possible to always apply the back tension to the wires W1 and W2, the wire W is previously wound up to the S-bending point on the circumference of the winding. To mark the wire W. After that, the supply device 40 rewinds the product with a predetermined tension, and stops when the marking point reaches a predetermined position of the S bending device 111 to perform the S bending process.

Since the stop point can also be read as the angular position of the rotary table 79, a control device having a teaching function is provided to store the position data.
The teaching position data can be extracted and used when winding each section coil 25a. In particular, in this case, the rewinding is performed while applying a predetermined unwinding tension, so that the wire is bent and deformed or the elongation rate changes, so that when the wire is wound again, the position of the wire, particularly the S bending point, is reduced. There is no risk of shifting.

As described above, according to this winding apparatus, the working efficiency is improved by the mechanization of the winding operation. Since the chance of touching the wire rod during the winding operation is reduced, the safety of the operation is also improved. In addition, the winding work can be performed without a skilled worker, and the quality of the winding can be stabilized.

Embodiment 2 In the embodiment shown in FIG. 1, it is assumed that the height of the worktable 30 is fixed at a fixed height from the floor F, and the turntable 54 and the rotary table 79 are fixed.
Are raised and lowered together. However, for example, the following is also possible. The winding elevating device 71 of the winding machine 70
, And the former 81 is rotatably supported at a predetermined height from the floor F. And the supply drum 20
The work table 30 is moved up and down as the winding 25 is formed on the former 81 and the winding position changes, so that the wire W between the supply drum 20 and the former 81 keeps a substantially horizontal position.

If it is not necessary to provide the pre-processing apparatus 100, even if one of the supply drum 20 and the winding die 81 is moved up and down, the supply drum 20 and the winding die 81 are not moved.
Since the horizontal posture of the wire W between them can be maintained, only one of the elevating device 41 or the winding elevating device 71 may be provided.

The powder clutch 55 of the drum driving device 51
In the above description, the supply drum 20 is provided with a tension and a braking force during rewinding, but a motor with an eddy current coupling may be used instead of the powder clutch 55.
In addition, although the two wires supplied from the two supply drums 20 are shown in parallel, it is needless to say that the same can be achieved even if the number of parallel wires is changed.
