DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal band winding device, and more particularly to a metal band winding device suitable for use in a line for dividing a metal band such as a steel band into widths.

[0002]

2. Description of the Related Art Generally, a metal strip such as a steel strip is unwound from a coil shape to a band shape, and is subjected to some processing (heat treatment, surface treatment, etc.) while being conveyed, and thereafter is wound up (referred to as a tension reel). However, in the case of winding up with a tension reel, in general, at the end of winding, a metal band presser Snubber roll is provided. As the snubber roll, a flat roll having a body length corresponding to the coil width is usually used.

In addition, in lines (slitter lines) that divide the metal strip into a plurality of pieces in the width direction, in order to prevent the width-divided metal strip from being distorted in a telescopic shape, the edges of the split metal strip are guided to guide each split. A separator is provided to prevent the metal strip from being offset in the width direction. Fig. 3 shows the separator
As shown in the figure, a plurality of ring-shaped fins 11 are composed of a hydraulic arbor shaft (a shaft whose diameter can be expanded and contracted by applying or removing hydraulic pressure between double pipes), both ends of which are supported by bearings 9. It is fitted to the separator shaft 4 via a sleeve 12. Fin 11 is usually integrated with sleeve 12, and the separator shaft (hydraulic arbor shaft)
When the diameter of the fin 11 and the sleeve 12 are reduced / increased, the fin 11 and the sleeve 12 are slidable / fixed with respect to the separator shaft (hydraulic arbor shaft) 4. It can be changed accordingly.

In the slitter line, the width of the metal band is not divided in some cases. However, it is impossible to substitute the separator with the snubber roll for the metal band not divided in width. In the conventional slitter line, since there is not enough space for installing the tension reel, conventionally, as shown in FIG. 4, a winding core for winding the metal band 10 fed from the pinch roll 8 is provided. A swivel arm 3 driven by a hydraulic cylinder 2 is provided at a predetermined position (upward in the case of upper winding, lower in the case of lower winding) with respect to 1, and a snubber roll shaft (not shown) and a separator shaft 4 The shaft replacement method of replacing and mounting is adopted.

In FIG. 4, reference numeral 7 denotes a rotary changer (shaft changing device) separately provided offline for replacing the snubber roll shaft and the separator shaft 4, and the changer 7 has a rotating arm and a shaft to be replaced (replaced). A snubber roll shaft and a separator shaft 4) to be formed can be supported at both ends of the rotary arm. In the shaft changing operation, the slitter line is stopped, the turning arm 3 is turned, and the shaft mounting portion at its tip is moved to the position of the shaft to be replaced supported by the changer 9 as shown in the figure, and the shaft to be replaced is moved to the rotating arm 3. It is performed by the procedure of setting the shaft at the tip of the shaft.

[0006]

In the above-mentioned conventional method, a device (swing arm 3) for pressing a snubber roll or a separator is used.
In addition, the changer 7 must be provided separately from the hydraulic cylinder 2), so that the equipment is complicated and a high investment is required. If the space for installing the changer cannot be secured, the operation cannot be performed.

Further, the fins 11 (see FIG. 3) fitted to the separator shaft 4 drawn off-line by the changer 7 are recombined manually, but the fins 11 are integrated with the sleeve 12 and are integrated. Is surrounded by a ring, so that the sleeve 12 must be removed and inserted, and there is a problem that the work load is large. In addition, the bounce of the tail end of the width-divided metal band is substantially prevented by being pressed by the sleeve 12 at the base of the fin 11 on the separator shaft 4 in FIG. Therefore, there is a problem that the sleeve life is shortened or the sleeve 12 needs to be made firm.

The present invention has been made in view of the above-mentioned problems of the prior art,
An object of the present invention is to provide a metal strip winding device that can reduce the work load of switching functions between snubber rolls and separators with a slitter line, can be configured at low cost, and can save installation space.

[0009]

According to the present invention, there is provided a snubber roll for preventing a tail end of a metal band from jumping up, comprising a core for winding one or a plurality of width-divided metal bands in a coil shape. In a winding device for a metal band having a separator that prevents the width direction deviation of a plurality of strips in the width direction and a revolving arm capable of supporting a snubber roll and a shaft of the separator, the snubber roll and the separator share the same axis,
The outer peripheral portion of the snubber roll is composed of a plurality of sleeves that can be divided in the axial direction and can be fixed at an arbitrary position in the axial direction. The fins of the separator can be divided in the circumferential direction and can be attached and detached between the plurality of sleeves. It is a winding device of a metal band characterized by the above.

[0010]

DETAILED DESCRIPTION OF THE INVENTION As shown in FIG.
A winding core 1 for winding one or a plurality of width-divided metal strips 10 into a coil shape is provided, and further, a snubber roll for preventing the tail end of the metal strip from jumping up and preventing the metal strips from shifting in the width direction. In a winding device for a metal band having a separator and a revolving arm 3 capable of supporting a snubber roll and a shaft of the separator, for example, as shown in FIG.
The snubber roll and the separator are configured to be able to be shared by the shared shaft 13.

In order to enable such a dual use, the diameter of the common shaft 13 is made variable, and the outer periphery of the snubber roll is constituted by a plurality of sleeves 5 which are divided in the axial direction and can be fixed at an arbitrary position in the axial direction. The fins 6 of the separator are configured to be circumferentially dividable and detachable between the plurality of sleeves 5. According to this configuration, when the width division of the metal band is not performed, the sleeve 5 is caused to function as a snubber roll by moving the sleeve 5 to the center of the common shaft 13 as shown in FIG. As shown in FIG. 1B, according to the number of divisions and the division positions, the fins 6 can be functioned as separators by being sandwiched between any two adjacent sleeves 5. become. Since the fins 6 can be divided in the circumferential direction (half in this example), it is not necessary to pull out the sleeve 5 from the shared shaft 13 at the time of mounting.

Furthermore, since the entire plurality of sleeves 5 between the fins 6 receive the impact load of the tail end rising as snubber rolls for the divided metal strip, the burden on the sleeves 5 is reduced and the life thereof is extended. The hydraulic arbor shaft may be used for the common shaft 13. As the sleeve 5, a small-width steel ring (preferably a urethane-lined one) or the like can be used. The width of each of the sleeves 5 is preferably about 10 to 50 mm from the viewpoint of ease of handling, and the number of the sleeves 5 is 50 to 50 to the maximum width of the undivided plate from the viewpoint of having a function as a snubber roll.
It is preferable that the number be such that it can contact a width of about 70%. Further, as the fin 6, for example, a disk-shaped steel member having an outer diameter larger than that of the sleeve 5 as shown in FIG.

If there is a possibility of circumferential displacement between the sleeves 5 or between the sleeves 5 and the fins 6 when the metal strip contacts, for example, as shown in FIG. By providing the pin 14 and a pin hole (not shown) for fitting the pin 14 on the other side, such circumferential displacement can be prevented. As described above, since one shared shaft 13 has both the functions of the separator and the snubber roll, according to the present invention, the troublesome separator and snubber roll depending on the presence or absence of the width division conventionally required by the metal band slitter line is used. There is no need to replace the shaft, the work load is reduced, and the productivity is improved. In addition, the changer (the member 7 in FIG. 4) is not required, so that equipment costs and installation space can be reduced.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a slitter line for dividing a steel strip having a maximum plate width of 1300 mm into widths will be described. The application form is basically as shown in FIGS. 1 and 2, and the winding method is upper winding. As the common shaft 13 in FIG. 1, a hydraulic arbor shaft (member 4 in FIG. 3, hereinafter abbreviated as shaft) used for a conventional separator shaft was used. This shaft can be expanded / contracted (diameter expansion / diameter reduction) by adjusting the hydraulic pressure as described above.

As the sleeve 5, a steel ring having an outer diameter of 140 mm and a width (= length in the axial direction) of 22 mm with a urethane lining on the surface is applied, and 34 of these are fitted on the shaft. Approximately 58 of division maximum board width 1300mm
%). As the fin 6,
A steel disk (outside diameter: 180 mm × thickness: 5 mm) was half-split and hard chrome plated on the surface (half-split disc).

In this embodiment, it is essential to provide the pin (member 14 in FIG. 1) and the pin hole, since a sufficient holding force can be secured by the expansion of the shaft and there is no concern about the above-mentioned circumferential displacement. However, a pin and a pin hole were provided in consideration of the workability of fin attachment. When the width division of the steel strip is not performed, the sleeve 5 is moved toward the center of the shaft and fixed by expanding the shaft.
In order to hold the tail end of the steel strip as a snubber roll, and to perform width division, the shaft is contracted and the sleeve 5 is slid to arrange the half-split disk between the sleeves 5 in accordance with the width division position. A gap is formed, and the two half-split discs are arranged and sandwiched in the gap so as to form a disc, and the shaft is expanded to fix the disc at that position. The section was guided to prevent the steel strip from being shifted (or straightened if already slightly shifted).

As a result, the changer is not required, and the place where the changer is installed and the space around the changer can be effectively used for other purposes, and the setup time due to the presence or absence of the width division is greatly reduced from the conventional about 8 minutes to about 4 minutes. Shortened to

[0018]

As described above, according to the present invention, it is not necessary to exchange the shaft between the separator and the snubber roll, which is required according to the presence or absence of the width division in the metal band slitter line. The load is reduced, the productivity is improved, and the changer that has conventionally been required to be installed off-line is not required, so that the equipment cost and the installation space can be saved.
