Abstract

PURPOSE:To prevent deviation of winding position, by controlling rotations of the winding shaft and of the feed roller so as to allow a predetermined length of steel strip to be wound in each winding rotation, by detecting the inclination of the outer peripheral face of the wound strip and by shifting the axis of the winding shaft by a predetermined angle. CONSTITUTION:A winding shaft 23 makes one rotation to wind up a predetermined length of a steel strip 1, and the strip is cut with cutting blades 22 at the terminating point. A rewinding belt 28 is rotated by the outer peripheral length corresponding to the length of the wound steel strip 1. In accordance therewith, a pulse generator 30 measures the length of the steel strip wound by one rotation and generates a signal. According to this signal, ALU commands the length of the steel strip to be wound by next one rotation and controls the rotations of the feed roller 16 and winding shaft 23 so as to wind the predetermined length of steel strip. When a steel strip 1 having deflection in its plate thickness on the both sides is wound, it is wound into a trapezoidal shape so that the outer peripheral face of the wound strip is inclined to the axis of the winding shaft 23 by the angle theta. When this inclination angle theta is increased, the steel strip 1 comes to shift to the side where the thickness is smaller, so that the winding shaft 23 is rotated by the angle beta to incline the fed steel strip 1 by the angle beta so as to approximate it to the arc-shape steel strip 1'.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a manufacturing apparatus for manufacturing a one-turn cut type wound core used in transformers and the like.

[Technical background of the invention and its problems]

As shown in Fig. 1, the general structure of a one-turn cut type wound core is to bend a plurality of steel strips 1a, Each steel strip 1a, 1b, 1c...
The cuts (butt portions) zaj2b, 2c...2n of zn are arranged by sequentially changing the position in the circumferential direction for each winding of the wound core,
It returns to its original position every predetermined number of turns.

Therefore, the length of each copper strip 1a, Ib, IC...1n from one cut to another is equal to the circumference of each winding that each copper strip constitutes.
The size is the sum of the wrap length up to the cut (butt part) of the next winding.

To manufacture such a wound core, as shown in FIG. 2, first cut out the hoop material and mark the cutting position 3a (alpha) of the band I.

Add 3b...3m, and mark 3a, sb...
Mark 4 is marked on the opposite side of 3 m by sawing, and this copper strip l is fed out and the part marked with mark 3 nl is cut with a cutting blade 5,
51, and then mark 3Tn-1+...31)
,,? Cut part a and make these cut pieces into 5 pieces.
- 10 sheets are put together as one group, and the cutting position is returned to the 3 m mark and the steel strip I is cut in the same manner as the next group. Each cut steel strip is bent into a circular shape according to the diameter of each winding, and the bent copper strips 17 are overlapped inside and out for each winding to align the marks 4 at 11A of that diameter. Assemble one group. Similarly, in the next group, each cut copper strip is bent and stacked on top of each other in the order of diameter. The disadvantage is that productivity is low because all processes are performed manually.

Therefore, in the past, the steel strip was manufactured by automatically controlling the process of sequentially winding the steel strip around a winding shaft with a winding length corresponding to each winding of the core, and then cutting and folding the steel strip with a cutting blade. Development of a device is being considered.

However, generally, steel strips are not necessarily equal in thickness on both sides in the width direction due to rolling manufacturing reasons, and the thicknesses on both sides in the width direction differ by several inches. For this reason, when a steel strip is wound up in the above-mentioned automatic manufacturing apparatus, the copper strip is wound into a conical shape due to the difference in the thickness of both sides of the copper strip. As a result, the copper strip shifts in position α in 10 directions while being wound, making it difficult to wind it evenly and making it difficult to wind it.
A problem arises in that the ends of the core are not aligned, making it impossible to obtain a wound core of good quality.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and is capable of automatically winding and cutting a copper strip, and also prevents positional shift due to deviation in plate thickness during winding of the copper strip, thereby facilitating winding and improving quality. The present invention provides a wound core manufacturing device capable of manufacturing a shape-wound core with good one-turn cut.

[Summary of the invention]

The wound iron core manufacturing apparatus of the present invention cuts and analyzes the wound copper strip to a predetermined length with a cutting blade when sending a 611 band with a feed roller and winding it on a winding shaft, and then cuts and analyzes the wound copper strip into a predetermined length with a cutting blade. The core is manufactured by controlling the rotation of the feed roller to obtain a predetermined winding speed of the copper strip for each winding of the core. A detector detects the inclination of the copper strip, and a winding shaft position control device, which operates in response to a signal from the detector, displaces the axis of the winding shaft by a predetermined angle. In some cases, the copper strip is fed obliquely to eight axes.

The winding shaft 23 has a steel strip 1 for each winding corresponding to each winding of the winding core.
Wind up. The winding length of the copper strip for one turn when the winding shaft 23 rotates once is the length between the cuts at both ends of the steel strip I forming 47 turns, that is, the circumferential length of the copper strip for one turn. plus the length to the next cut. This winding length can be expressed mathematically as shown in FIG.

L = Circumference length of copper strip for 1 turn + P (cut pitch) + 2π1
(1 is the thickness of the copper strip). Therefore, P+2πt is the length of the steel up to the cut for the next winding. Therefore, when winding the steel strip 1, the winding shaft 23 rotates once, winds up the steel strip 1 corresponding to the circumferential length of one winding, and then winds up the steel strip 1 corresponding to the circumferential length of one winding. The steel strip L is wound up by rotating for the same amount of time.

When the winding shaft 23 rotates once and winds up the steel strip 1, winding ii'
The length of the steel strip 1 existing between 1123 and the cutting blade 22 is the length up to the next cut. Note that the winding It 7 winds the copper strip 1 from several turns to several turns, and cuts 2a of the steel strip 1;
When tb,2c·=2n reaches point B, L=perimeter−A+2πt.

I will now explain the general effects. In FIGS. 3 and 6, the feed rollers Z 6 , 1 G' are connected to the support 11
The winding shaft 23 sends the steel strip I held at the winding shaft 23 toward the winding j'l+2s with a length corresponding to one winding length. roll:! il+,? s is the feed roller 16,
The steel strip 1 sent by the steel strip 1 is rotated once and wound to a predetermined length, and the cutting blade 22 cuts the steel strip 1 at the winding end point of the winding shaft. The pull-in belt 28 presses and presses the outer circumferential side of the steel strip 1 wound around the winding shaft 23, and rotates by a length corresponding to the outer circumferential length thereof. In response to this, the pulse generator 30 measures the copper strip winding length for one turn of the winding shaft 23, and in response to this signal, the calculator 52 measures the copper strip winding length for the next one rotation of the winding @2S. Based on this command, the feed roller rotation control device 2θ and the winding shaft rotation control device 27 feed the steel strip I to the feed roller 16 and the winding shaft 23 by a length corresponding to a predetermined winding length. By repeating this operation, the steel strip Z (Za... zn), its cut (butt part 2a...
・A wound core is manufactured by winding every 11th turn so that 2n) is shifted in the circumferential direction. Add further explanation.

To explain the operation of the computing unit 52, when the winding shaft 23 rotates and the operating body 33 drives the winding shaft origin switch 32, the counter 58 is erased and an inverse value measuring the circumference wound by the winding shaft 23 is generated. It's all set. Here, as the winding 111] 23 further rotates, the winding belt 28 also rotates, and the pulse generator 30 provided on the guide roller 29 also rotates to generate pulses, thereby increasing the count value of the counter 58. is increasing.

At this time, when the winding shaft 23 rotates once and the winding shaft origin switch 32 is operated again by the operating body 33, the count value of the counter 58 is held in the count holder 59 and is sent to the arithmetic unit 52. The counter 58 is cleared again as the length is entered. In order to repeat this operation each time the winding shaft 23 rotates once and the winding shaft origin switch 32 operates accordingly, the circumference of the steel strip 1 wound on a new winding shaft 23 is always input to the calculator 52. It will be done. Here, when the winding length of the steel strip 1 is input to the calculator 52,
The calculator 52 calculates the winding length of the steel strip l to be wound next. The winding length of this steel strip is as described above.

Next, the operation of the entire device will be explained. The copper strip 1 is rewound by unwinding rollers 12, 12' and is always connected to the feed roll 16,
A slack is provided in front of l 6'. Here, the winding shaft 23 is rotated as described above, and then the winding length of the steel strip l to be wound around the @shaft 23 is calculated and input to Ff52.

Next, when the steel strip 1 is wound around the winding shaft 23 and the apparatus is started, a command for the length of the steel strip 1 to be wound around the winding shaft 23 is output from the computing unit 52 to the pulse generator 53. Pulse generator 5
Based on this instruction, 3 simultaneously outputs pulses corresponding to the length of the feed of the copper strip 1 to the difference counter 56 on the winding shaft side and the difference counter 54 on the feed roll side.
, l 5' is aromatic. As a result, although the steel strip 1 on the winding shaft side and the steel strip 1 on the feed roller side are cut, they move synchronously as if they were one steel strip. As a result, the difference between the pulses from the pulse generator 53 and the pulses from the pulse generator FIU so of the winding belt 28 is counted by the difference counter 56, and digital-to-analog conversion is performed so that the difference is always "0". The servo motor controller 26 of the winding shaft rotation control device 27 is operated via the device 57, whereby the winding shaft 2 is controlled by the servo motor 24 and the rotary generator 25.
3 is rotated only outside the command from the pulse generator 53. Similarly, the servo motor of the feed roller rotation control device 2o is controlled so that the difference between the pulse from the pulse generator 53 and the pulse from the pulse generator 2 is set to rOJ on the sides of the feed rollers 1G, 15'. The feed roller 16 is operated by the servo motor 17 and the rotary generator 18.
Z6' is rotated and the 1:1 belt 1 is sent to the winding shaft 23. Next, when both the winding shaft 23 and the feed rollers Z 6 and Z 6' have completed their operations, the cutting blade 22 is activated to cut the steel strip 1. The above operation is repeated a predetermined number of times to produce a wound core.

Note that when winding the copper strip, due to the tension of the winding belt 28 applied by the cylinder 31, the winding shaft 23 is drawn toward the cutting blade 22 (I! While taking it.

As the outer diameter of the steel strip wound on the winding shaft 23 increases, the winding shaft 23 moves in the direction of 1>1 from the cutting blade 22, and when the steel strip winding is completed, the spring 41 moves the movable table 38, Cutting blade 2
2 to make it easier to remove the steel strip 1 from the winding shaft 22.

Next, an explanation will be given of the effect of preventing the positional shift of the steel strip 1 due to a deviation in the thickness of the steel strip 1 during winding of the steel strip 1. As shown in FIG. 8, the steel strip 1 has a thickness of 1.5 mm on both sides in the width direction. ,1
．． There is often a difference of several inches in size. When winding a steel strip 1 with equal thickness on both sides using the winding shaft 23, the steel strip 1 is fed from a direction perpendicular to the winding shaft 23':'41a and is wound. Therefore, it can be wound evenly as shown in FIG. However, when the steel strip l having uneven plate thickness on both sides is wound around the winding shaft 23, as shown in FIG. 10, the steel strip 1 has a smaller winding diameter D1 on the thin side and The winding diameter is wound into a large trapezoidal shape, and the winding outer peripheral surface thereof is inclined at 0 degrees with respect to the l1it line of the winding shaft 23. At this time, the winding diameter is = number of windings “I”
.

D2=number of turns x t, and there is a copper band winding outer peripheral surface. When the inclination angle θ of the outer circumferential surface of the copper strip winding increases, as shown in FIG. As a result, the steel strip 1 has a positional deviation S between the tip and the rear end.
occurs, making winding by the winding shaft 23 difficult. In order to prevent this positional shift, it is possible to wrap a copper strip 1' in an arc shape as shown by the diagonal double-dashed line in Fig. It is difficult to form it in an arc shape. Therefore, in the present invention, the steel strip I is fed so as to be inclined by β degrees with respect to the axis of the winding shaft 23 so as to approximate the arc-shaped copper strip 1'. In this case, according to the invention, volume mb 2. ? is rotated by β degrees.

When winding the copper strip, the winding shaft 23 is normally positioned so that the 1iIII wire is perpendicular to the copper strip feeding direction, so that the copper strip 1 is evenly wound. 5. As shown in FIG.
The steel strip 1 wound around s is always in contact with its outer peripheral surface, and the actuator 717B of the potentiometer 47 is pressed by a spring and is in contact with the head lever 45. When the steel strip 1 is wound evenly, the head lever 45
The position [δ is parallel to 3. but.

When the steel strip I is wound into a trapezoidal shape, the head lever 4
5 is pushed by the piston rod 44a of the cylinder 44 and the actuator 47a of the potentiometer 47, and the piston rod 4
The head roller 46 is rotated about the pivot portion of the steel strip 1 toward the outer circumferential surface of the steel strip 1 to be wound, and the head roller 46 is brought into contact with the outer circumferential surface of the steel strip 1.

The head lever 45 is located parallel to the winding outer circumferential surface of the steel strip 1, and is inclined with respect to the axis of the winding shaft 23 at the same inclination angle θ as the steel strip winding outer circumferential surface. Actuator 4 of potentiometer 47
7a protrudes with a length corresponding to the inclination angle θ of the lever lever 45. Then, the potentiometer 47 becomes ζ
f81 The above-mentioned inclination angle of the outer circumferential surface of the belt winding failure is detected. Digital detection signal power is output from the potentiometer 47,
This signal is converted into an analog signal by the digital-to-analog converter 61 and input to the difference counter 61. The difference counter 6I calculates the correlation between the detected inclination angle of the outer circumferential surface of the copper strip to be wound and the outer diameter of the winding, and sends a signal to the servo motor controller 62 to rotationally displace the winding shaft 23 by a predetermined angle in a predetermined direction. Output to. The servo motor controller 62 receiving this signal drives the servo motor 48 to rotate. The rotation of the servo motor 48 rotates the small output wheel 50, rotates the gear 51 meshing with the small gear 5o, and rotates the turntable 34 together with the gear 51. Due to the rotation of the turntable 35, the winding shaft 23 is aligned with the axis of the winding shaft 23 on the side where there is an intersection 0 between the extension line along the copper strip winding outer peripheral surface and the axis of the winding 111h23, as shown in FIG. It is rotationally displaced in a direction in which the angle with the copper strip feeding direction is smaller than 90 degrees. In this case, the rotating shaft of the servo motor 48 is connected to the pulse generator 49.
is detected and fed back to the difference counter 61.

The differential counter 49 is connected to the potentiometer 47 of the detector 42.
Signals and pulses from,,! The servo motor controller 6
2. In this way, the winding shaft 23
By winding the steel strip I by controlling the angle of the axis of the steel strip I, even if the steel strip I is wound in a trapezoidal shape due to a deviation in its thickness, the occurrence of misalignment of the steel strip 1 can be prevented. +h can be done.

Although the rotation angle of the winding shaft 23 is large in the illustration, it is actually very small. A specific example thereof will be explained with reference to FIG.

Width W 150vl, plate thickness t1 0.345ia,
A steel strip l with a t2 of 0.350 is wound on a winding shaft 23 with a diameter of 160 mm.

Table 1 shows the values of each part when the wire is wound 300 times.

As is clear from Table 1, the inclination angle β of the winding shaft 23 is very small at approximately 18 degrees even when the copper strip 1 is wound 300 times.

On the other hand, if we look at β10 from Table 1 above, we get Table 2.

Y is -2-)B, and by simply detecting diff (or Y), that is, the dimensional deviation corresponding to the inclination angle of the winding outer circumferential surface with a potentiometer via the head lever, the winding shaft can be adjusted to a predetermined inclination angle. It can be rotated to β.

By performing this operation according to the inclination angle of the winding outer circumferential surface, it is possible to prevent the steel strip 1 from shifting and wind the steel strip 1 well, and to manufacture a wound core with uniform winding surfaces. can.

〔Effect of the invention〕

As explained above, the wound core manufacturing apparatus of the present invention can automatically wind and cut a copper strip.

In addition, even if there is a thickness deviation on both sides of the copper strip, the copper strip can be wound to produce a high-quality one-turn cut wound core.
