Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of winding the remaining width by cutting the side end portion of a running material coil in the longitudinal direction to form the remaining width, and winding this remaining width. - to do.

Generally, the width of the raw material coil is limited to several types due to the economic efficiency of pre-processing. However, from this 5 material coil, Sea 1 'a? When cutting out the sheet, there are an infinite number of widths because this is the size that will be used in the end, and as a result, it is necessary to cut the side ends of the material coil, resulting in a remaining width. If the remaining width is wide, it can be used as a product as it is or after some processing. It is proposed that. The winding method in the first sentence is as follows: 1. A raw material coil 1 continuously unwound from a payoff reel (not shown) is taken over by a pinch roll 2, and then slits are formed at both ends thereof by a trimmer 3, and a strip 4 of a predetermined width is formed.
and the remaining width 5 and ' as the remaining part. The strip 4 is then cut one after another into a predetermined cutting length by a shear 6 to form a sheet 7. On the other hand, the remaining width 5 descends while being guided by the first guide table 8, and the bit 9
After forming the loop 10 within the bit 9, a second guide table 11. Tensioning device 12. It passes through a deflector roll 13 and is then wound up by a winder 14 installed in the bit 9 directly below the IJ knob 4.

Moreover, the winding method shown in FIG. 2 is almost the same as described above, but
Second guide table 11. A tension applying device 12, a deflection roll 13, and a winder @14 are installed on a pedestal 15.

Winding is performed directly above the strip 4.

However, in any of these winding methods, the tension applying device 12, which is indispensable for the first winding, is required.
, the deflector roll 131 and the winder 14 are located directly below or directly above the IJ gear 4, so the pinch roll 2. It is not possible to arrange the shear 6, etc., and as a result, the total length of the shear line becomes long, and it takes a long time for the shear line to pass through the strip 40, reducing efficiency. Further, since it is difficult to thread the sheet into the winder 14 within the bit 9 or at a high place and to extract the coil from the winder 14, efficiency is further reduced. Moreover, in the former case, the basic cost is high to manufacture the bit 9, and in the latter case, since the heavy winding machine 14 is mounted on the emperor, not only does the bridge 15 need to have great rigidity, but also has a wide range. A work deck is also required, which increases the overall equipment cost.

An object of the present invention is to provide a method for winding up the remaining width in which equipment such as a winding machine necessary for winding the remaining width can be installed on the plane where line equipment is installed. .

In order to achieve the above object, the present invention provides a method for winding the remaining width by cutting the side ends of a running material coil in the longitudinal direction to form the remaining width, and winding the remaining width. , the remaining width is bent and run in reverse, and the coil is wound on the side of the material coil.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is a partially cutaway schematic perspective view showing an embodiment in which the present invention is applied to a shear line, and FIG. 4 is a partially cutaway side view similar to FIG. 3.

In this embodiment, a pair of trimmers 21 are installed downstream of a payoff reel (not shown), and each trimmer 2
1. consists of a pair of slitters 22 that rotate freely. The raw material coil 23 unwound from the crystalline payoff reel is cut at both ends by trimmers 21 in the longitudinal direction to form a strip 24 of a predetermined width, a wide remaining width 25, and a narrow remaining width 2.
It is divided into 6 parts. A pinch roll 27 is provided on the downstream side of the trimmer 21 to take off the strip 24, and the pinch roll 27 is comprised of a pair of rolls 28 that are driven by a drive motor (not shown) and rotate while holding the IJ tube 24 between them. A rotary shear (not shown) is installed downstream of the pinch rolls 27, and this rotary shear sequentially cuts the strip 24 to a set cutting length to form a sheet 29. When the remaining width cut by the trimmer 21 cannot be reused (1), for example, when the width is 20 to 30 mm or less, the degree of deformation is not taken into consideration (as in the remaining width 26). After the running direction is forcibly changed by rollers 30, it is wound up in a scrap winder 31 and made into scrap.

Strip 2 between trimmer 21 and pinch roll 27
A bit 32 is provided directly below the bit 4.

In the figure, 33 is a first guide table, and this first guide table 33 is composed of four parallel small diameter rolls 34.
The remaining width 25 is guided into the bit 32, and no external force is applied to the cutting portion by the trimmer 21. The remaining width 25 that has passed through the first guide table 33 forms a hanging loop 35 in which the remaining width 25 is somewhat twisted. On the side of the strip 24 upstream from the loop 35, a shear line device, such as a trimmer 21. A winder 36 is installed on the same plane as the pinch roll 27, and this winder 36 bends at the rising end of the loop 35 to rotate the strip 240 at 180 degrees with respect to the running direction. The remaining width 25, whose running direction is inclined at an acute angle A with respect to the running direction of the strip 240, is wound up in an orderly manner. At the reversal position of the remaining width 25, a '2nd guide wheel 37 is installed.

This second guide table 37 has four small-diameter rolls 38 arranged along the curvature of the remaining width 25 at the reversed position, and as these small-diameter rolls 38 roll into contact with the remaining width 25, the loop 35 is Stably supported. Immediately below the second guide cheagle 37, there is a remaining width 25 after reversal.
A pair of rails 39 are installed parallel to the rails 39, and the second guide table 37 can be moved along the rails 39 by rolling the rollers 40 of the second guide table 370 on these rails 39. A deflector roll 41 and a tension applying device 42 that applies tension necessary for winding to the remaining width 25 are provided between the second guide table 37 and the winder 36 .

Next, the operation of the above embodiment will be explained.

The raw material coil 23 unwound from the payoff reel has slits formed in the longitudinal direction by trimmers 21 at both ends thereof, and a strip 24 of a predetermined width and a wide remaining width 25.
and the narrow remainder @26. The strip 24 is taken up by a vinyl roll 27 and then cut into a set cutting length by a rotary shear to form a sheet 29.

The narrow remaining width 26 that can be reused is forcibly changed direction by a roller 30 and then wound up as scrap in a scrap winder 31. On the other hand, since the reusable remaining width 25 needs to be wound up with almost no deformation, it is wound up as follows. That is, the trimmer 21
Immediately after cutting W'r, the remaining width 25 is guided into the bit 32 by the first guide eagle 33 and forms a depending loop 35. In this loop 35, the small diameter roll 38 of the second guide table 37 is arranged parallel to the rotation axis of the winder 360, so that it is somewhat twisted. However, since the total length of the remaining width 25 in the loop 35 is long, no permanent distortion occurs in the remaining width 25. Next, the remaining width 25 is determined by the rise 9 of the loop 35.
At the end 111, while being supported by the small diameter roll 38 of the second guide table 37, the strip 240 makes an E bend and is reversed by 180 degrees with respect to the running direction of the strip 240. The reversal position of this remaining width 25 is on the intersection O of the extension line B of the center of the remaining width 25 before reversal and the extension aC of the center of the remaining width 25 after reversal, or,
It is located on the side of the extension line C that is farther away from the winder 36 than the intersection O. Furthermore, since the winding machine 36 is installed on the side of the IJ tube 24, the running direction of the remaining width 25 after reversal is inclined at an acute angle A with respect to the running direction of the IJ tube 24. ing. In addition, the width of the remaining width 25 is 40~3
In the case of a stainless steel plate having a weight of 0.00 mg and a thickness of 0.2 to 2.0 mm, the acute angle A is preferably about 60 degrees. In addition, this acute angle A should be made to stabilize the loop 35 because the larger the remaining width 250 and the thicker the thickness, the thicker the rigidity (and the harder it is to deform). (Here, as mentioned above, since the remaining width 25 is bent to run in reverse, the first winding position is The remaining width is 2.
5 does not need to be bent to the extent that permanent deformation occurs during travel. Next, the remaining width 25 is given tension necessary for winding by a tension applying device 42, passes through a deflector roll 41, and is neatly wound up by a winding machine 36. Next, material 2
3 becomes thicker.

If the width is thick (if the second guide table 37 is
9 to the side away from the winder 36 from the intersection O. This is because the rigidity of the remaining width 25 is large (as a result, the radius of curvature of the remaining width at the reversal position becomes large, and as a result, the one reversal position moves to the side away from the winder 36).

In the above embodiment, the remaining width 25 on the side of the winding position (winding machine 36) is wound up, but the remaining width on the side opposite to the winding position (the side where the scrap feeder 31 is installed) is It is also possible to wind it up using 36. In this case,
The second guide table needs to be moved on the extension line C to the side opposite to the winding position. In addition, in the above embodiment, the force ζ'' trimmer 1 describes the so-called sol cut method in which the material coil 23 is cut by the trimmer 21 that rotates freely while the strip 24 is taken up by the pinch roll 27.
When it is necessary to form a loop between the trimmer and the pinch roll 27, a so-called drive cut method in which a trimmer is driven and rotated may be adopted.

Furthermore, the above embodiment is the first embodiment. Second guide table 33.
37 is constructed from four small-diameter rolls 34 and 38, but any type may be used as long as it can support the traveling plate-like body.

As described above, one aspect of the present invention is a method for winding up a remaining width in which the side end portion of a running material coil is cut in the longitudinal direction to form a remaining width, and the remaining width is wound up.
Since the remaining width is bent and runs in reverse, and is wound on the side of the material coil, the equipment such as the winding machine necessary for winding the remaining width is installed on the plane where the line equipment is installed. It can be installed on top. As a result, the overall length of the line is shortened, the threading work and the work of extracting the coils become easier, production efficiency is improved, and equipment costs are also reduced.
