Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coil winding misalignment correction device for a coil wound on a rolling line, an annealing line, or the like.

[0002]

[Prior art]

 Conventionally, since it is not possible to apply tension between the final stand and the winder at the rear end of the coil wound on the winder on the rolling line or the annealing line, approximately one turn is required at the end of the coil winding. In many cases, winding is misaligned and the coil edge pops out to the side, resulting in uneven coil winding.

As shown in FIG. 5, the coil winding misalignment caused by such coil winding deviation is often the case where the edge of the winding end end 16 of the coil 12 is gradually displaced as the edge travels most to the side. Coils with uneven edges are packed manually after being manually repaired by workers at the packing line in the next process, but this is problematic in terms of labor saving and unsafe work. In addition, it is necessary to insert a coil lifter into the inner diameter of the coil for lifting to correct the edge misalignment, which is a case after the folding of the packing paper, which may cause paper and blurring.

By the way, as disclosed in Japanese Utility Model Publication No. 56-48403, which performs centering of a coil, when the coil is unwound from the coil unwinder, the coil rewound by a guide roller is used. It is known that the coil is centered by being sandwiched from both sides and always sent to the center of the path, and the coil can be rewound by firmly holding the coil by the drum diameter enlarging means and applying the back tension.

However, the one disclosed in the above publication rewinds by a rewinding machine arranged on the line to center the coil, and the wound coil finishes coiling at a packing work place or the like. The purpose, configuration and effect are different from those for correcting the coil winding misalignment at the end, and it cannot be applied to correct the coil misalignment transported to the coil packing place.

In order to solve the above-mentioned problems of the prior art, the applicant of the present invention disclosed in Japanese Unexamined Patent Publication No. 2-86533 "a pair of coils moving forward and backward on a guide frame facing a coil suspended by a lift. A plurality of expansion / contraction slicing guide rods radially extending in the coil radial direction are provided on the main body frame of the body, and the expansion / contraction body that is guided by the guide rods and is movable in the coil radial direction to freely expand and contract is located at a position corresponding to the coil outer diameter. After moving the coil up to the coil facing side of the expandable / contractible body, the presser plate for expanding and contracting the coil winding, which is elastically arranged by the pressing cylinder, is fed toward the outer diameter of the coil and the end of the coil winding is uneven. Method and apparatus for correcting the above. "

[0007]

[Problems to be solved by the device]

 Usually, the bare coil that enters the packing line has a band on the outer circumference, and it is not easy to correct the uneven coil winding on the outer circumference simply by pressing the holding plate with the holding cylinder. If the pressing force is not adjusted depending on the thickness, material, etc., the coil edge will bend. On the other hand, there is a problem that a large pressing force is required to correct the coil misalignment only by the pressing force of the holding plate, and there is a high possibility that the coil will bend.

The present invention has been made in view of the above circumstances, and is an improvement over the prior art proposed by the above-mentioned Japanese Patent Laid-Open No. 2-86 533, in which a coil unevenness is corrected by using a holding plate. An object of the present invention is to provide a device for correcting coil misalignment of a wound coil, which can reduce troubles such as bending of a coil plate edge.

[0009]

[Means for Solving the Problems]

 The present invention was inspired by the fact that vibration is used to align and move objects in parts feeders, etc. The gist of the invention is as follows. Means for Solving the Problems The present invention to achieve the above object is a wound coil provided with a plurality of coil misalignment correcting presser plates that are radially movable in the coil radial direction and that are expandable and contractable so as to face the coil winding end portion. In the coil winding non-uniformity correction device, a coiling non-uniformity correction presser plate is provided with a self-oscillating device for adjusting the vibration force on the back surface of each coil non-uniformity correction supporting the correction of the coil non-uniformity. This is a device for correcting coil winding irregularities.

[0010]

[Action]

 According to the present invention, while the pressing plate is being pressed against the coil winding non-uniformity at the end of the coil winding, the vibration force applied to the coil plate edge by the oscillator installed on the back side of the coil winding plate depending on the coil thickness and material. By adjusting (frequency, amplitude, etc.), it is possible to correct the coil irregularity without bending the plate edge portion of the coil.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In the coil winding irregularity correcting device for the wound coil of the present invention, an oscillator with adjustable vibration force is provided on the back of each coil irregularity correcting presser plate to assist in correcting the coil irregularity. Except for this point, the configuration is the same as that disclosed in Japanese Patent Application Laid-Open No. 2-86 533 proposed by the present applicant.

That is, as shown in FIGS. 1 to 4, a frame main body 1 traveling on a guide frame 2 is provided with a plurality of expansion / contraction threaded guide rods 3 extending in the coil radial direction. An expansion / contraction body 13 is set on each guide rod 3 by screwing. Each expansion / contraction body 13 is provided with a holding cylinder 6 on the side facing the coil 12, and a holding plate 4 is attached to the tip of the holding cylinder 6 via a U-shaped support frame 17. An oscillating device 18 is arranged on the back surface of the holding plate 4 (see FIG. 4).

As shown in FIG. 3, driving force transmission gears 9 are provided at the inner ends of the threaded guide rods 3, respectively, and the adjacent driving force transmission gears 9 are in mesh with each other. Therefore, since the adjacent driving force transmission gears 9 rotate in opposite directions one after another, the threads of the threaded guide rods 3 are oppositely threaded in correspondence with this rotation direction, and the expansion / contraction bodies 13 move in the same direction. It is designed to move in scaling.

One of the threaded guide rods 3 is provided with another drive force transmission gear 10 in addition to the drive force transmission gear 9, and the drive force transmission gear 10 is connected to the drive gear 14 of the drive motor 5. Are in mesh. Reference numeral 7 denotes a touch roller type plate edge detector for detecting the winding end of the coil 12, 11 a coil receiving saddle, and 15 a wheel attached to the frame body 1.

Next, the operation of the present invention having the above configuration will be described. With the coil 12 having the irregular coil windings suspended by the lift 8, the frame body 1 is moved forward to approach the side surface of the coil 12. Then, the drive motor 5 is driven to rotate the threaded guide rods 3 via the drive gear 14 and the drive force transmission gears 10 and 9 to move the expansion / contraction body 13 in the coil radial direction to correspond to the outer diameter of the coil 12. Stop at the position you want.

Subsequently, the pressing cylinder 6 provided on the expansion / contraction body 13 is operated to move the pressing plate 4 forward, and at the same time, the oscillation device 18 provided on the back surface of the pressing plate 4 is vibrated to be displaced from the outer circumference of the coil 12. Then, the protruding edge of the coil 12 is pressed in the width direction to correct the coil misalignment. At this time, a plurality of holding plates 4 may be oscillated by the oscillating device 18 and simultaneously pressed against the outer peripheral side surface of the coil 12 to correct the coil misalignment, but the touch roller type coil winding disposed near the outer periphery of the coil 12 may be used. The end-of-winding detector 7 detects the end-of-winding of the coil 12, and the presser foot corresponding to the coil portion following the end-of-coil winding 16 so that the end-of-winding coil 16 is finally corrected as shown in FIG. The coil edge is prevented from being crushed by pressing the edge of the coil 12 in the width direction to move the plate 12 forward from the plate 4 in the order of winding in the order of ... It is preferable from the point. As the coil winding end detector, an appropriate means such as a holding plate internal type can be used.

As described above, in the present invention, the oscillator 18 is arranged, and the pressing plate 4 attached to the front surface of the U-shaped support frame 17 is pushed forward while applying the vibration to the pressing plate 4. The coil winding irregularity can be corrected smoothly. The vibration force (frequency, amplitude, etc.) applied to the oscillating device 18 can be adjusted by the plate thickness, material, etc. of the coil. By selecting the optimum vibration force, the cold rolling line, annealing line, and surface The coil winding misalignment can be corrected for a wide range of coils such as processing lines without bending the coil edge. For example, the larger the frequency is from 1800 to 3600 VPM, the smaller the pushing force of the holding plate 4 by the holding cylinder 6 can be. At this time, the amplitude of the holding plate 4 by the oscillating device 18 is close to zero.

The pressing plate 4 preferably has a hard surface on the edge of the coil 12 but a little soft inside. For example, a material such as wood or urethane wound on a tin plate is suitable. According to the conventional means disclosed in Japanese Unexamined Patent Publication (Kokai) No. 2-86533, coil unevenness correction of a coil having a plate thickness of 0.6 mm or more does not adversely affect the quality such as edge bending and scratches. According to the present invention, the success rate of the coil misalignment correction is 80% or more, while the coil succession rate of the wound coil having the plate thickness of 0.4 mm or more can be 95% or more. It was

[0019]

[Effect of device]

 As described above, according to the present invention, it is possible to reduce the coil winding due to the labor saving without the manual work of the worker by the simple means of applying the vibration to the pressing plate by using the oscillation device. It is possible to easily correct the edge protrusion on the outer circumference of the coil. In particular, if the end of the coil winding is detected and the end of the coil is pressed at the end, the coil edge can be crushed if it is corrected sequentially from the part following the end of the coil winding along the coil winding direction by the holding plate. It can be easily corrected without causing.
