Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of slip flaw and top mark by keeping an expandable mandrel at the prescribed degree of opening, pressing a belt wrapper against the mandrel to start the coiling, retracting the belt wrapper while coiling the metallic strip after the metallic strip is coiled by the prescribed number of turns, and immediately expanding the mandrel to the maximum diameter. SOLUTION: When a mandrel 10 is started to turn, a belt wrapper 20 is advanced, a rubber belt 22 is pressed against an elastic sleeve 12, a tip part of a steel strip S is held between the elastic sleeve 12 and the rubber belt 22 to start the coiling, and the belt wrapper 20 is retracted when the turns of coiling reach the prescribed value, for example, 1.5-7 turns. The degree of opening of the mandrel 10 which has been set to the prescribed degree of opening of 95-98% is rapidly expanded to 100% to continue the coiling. A top mark flaw part is expanded in the circumferential direction, and the step between a tip part of the steel strip S and a lapped part of the coil is mitigated, slip flaws and top marks are are drastically reduced, parts to be scrapped are reduced, and the yield is improved.

2. Description of the Related Art In a continuous production or processing step of a steel strip, it is common to provide a winding device for winding the steel strip into a coil at the end or middle thereof. In recent wind-up facilities, particularly cold rolled steel strip wind-up facilities, a belt wrapper is often arranged around a mandrel to assist winding of the steel strip tip. One example will be described with reference to FIG. This figure is a front view of the main part of the winding equipment showing the initial stage of winding, 10 is a mandrel, 11 is a segment constituting the surface, 12 is an elastic sleeve fitted to the mandrel 10, 20 is a belt wrapper, 21 is the roll,
22 is an endless rubber belt, and S is a steel strip.

[0003] The mandrel 10 is rotated at a predetermined rotational speed by a driving device (not shown), and a segment 11 constituting the surface of the cylindrical portion is moved back and forth in the radial direction by an expansion and contraction mechanism such as a hydraulic cylinder (not shown) to move from the maximum diameter to the minimum diameter. The diameter can be expanded and reduced up to. On the other hand, the belt wrapper 20 includes a plurality of rolls 21 and an endless rubber belt
22 and an advancing / retracting mechanism (not shown) for moving them toward and away from the mandrel 10. When the rubber belt 22 approaches the mandrel 10 and presses it, the rubber belt 22 follows the rotation of the mandrel 10 and runs at the same peripheral speed.

[0004] The conventional operating procedure in such a winding facility is usually as follows. To start the winding of the steel strip S, first, the segment 11 of the mandrel 10 is expanded to make the mandrel 10 the maximum diameter, the belt wrapper 20 is advanced, and the rubber belt 22 is pressed against the surface of the mandrel 10 to push the mandrel 10. By rotating the steel strip S, the leading end of the steel strip S is sandwiched between the segment 11 and the rubber belt 22 to start winding the steel strip S. When the steel strip S has been wound by an appropriate number of turns and the slip of the steel strip S does not occur without being pressed by the rubber belt 22, the belt wrapper 20 is retracted from the mandrel 10. The steel strip S is wound around a coil with the mandrel 10 kept at the maximum diameter, and after winding, the segment 11 is contracted to make the mandrel 10 the minimum diameter, and the coil is pulled out of the mandrel.

[0005] Defects that tend to occur when the steel strip S is wound include a flaw called a top mark. This is shown in FIG.
Is a phenomenon to put a stepped flaw in a plate with step is wound thereon by a thickness of the strip S tip S 0 as shown in. To prevent this, the mandrel 10 is generally provided with an elastic sleeve 12 made of an elastic material such as rubber. Further, as described in JP-A-4-37416, the winding of the mandrel is started at a diameter smaller by about 1 to 10 mm than the maximum diameter,
There is also a method in which after winding a predetermined number of times, the diameter is increased to the maximum diameter to geometrically reduce the step. However, this publication does not describe at all about the relationship with the belt wrapper, nor does it describe how to prevent slip flaws described below.

Another typical defect at the time of winding a steel strip is a so-called slip defect. This is a defect caused by slipping of the steel strip in the initial winding, especially when the winding tension (top tension) in the initial winding is set to be relatively high because the steel strip is wound tightly. On the other hand, Japanese Patent Publication No. 5-30737 proposes a method of winding a steel strip to prevent slip flaws (referred to as oyster flaws in this publication) when winding the steel strip. According to this, at the start of winding, the mandrel opening is set to a predetermined opening of less than 100%, the belt wrapper is pressed against the mandrel to start winding, and the mandrel is wound at a predetermined winding number after winding starts. Opening
According to the company, the diameter is increased to 100% to enhance the pressing between the mandrel and belt wrapper, thereby realizing winding without slip.

In the invention described in Japanese Patent Publication No. 5-30737, although the purpose is different, the winding is started with a diameter slightly smaller than the maximum diameter, and the diameter is enlarged after the winding is started. Since it is the same as the invention described in the above-mentioned Japanese Patent Application Laid-Open No. 4-37416, it seems that no top mark appears at first glance.
It has been found that the method described in US Pat. No. -30737 hardly improves the top mark. This is because the diameter is increased while the belt wrapper is pressed, so that the tip of the steel strip cannot move rearward as the diameter increases and the wound steel strip is pressed against the step. It seems to be because.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail. Note that the winding equipment for implementing the present invention is the same as that shown in FIG. 1 as far as the range shown is concerned. The segment 11 of the mandrel 10 is expanded in diameter when a command to prepare to wind the steel strip S is given, and is maintained at a predetermined opening of less than 100%, for example, 95 to 98%. If it is less than 95%, the burden at the time of expanding the diameter is increased, which is not preferable. If it is more than 98%, the effect of the diameter expansion is reduced, which is not preferable.

When the rotation command signal is input and the mandrel 10 starts rotating, the belt wrapper 20 advances and the rubber belt 22 is pressed against the surface of the elastic sleeve 12 mounted on the mandrel 10. The steel strip S enters, the tip portion is clamped between the elastic sleeve 12 and the rubber belt 22, and the winding of the steel strip S is started. The steel strip S has a predetermined number of turns,
For example, when 1.5 to 7 turns are reached, the belt wrapper 20 is retracted. If the number of turns is less than 1.5, slippage occurs when the belt wrapper is opened. On the other hand, if the number of windings is more than 7, the amount of retraction of the steel strip tip due to the diameter expansion is insufficient, and the top mark prevention effect is small.

When the belt wrapper 20 is retracted, the mandrel 10 is immediately expanded to an opening of 100% (maximum diameter). The larger the timing of the diameter expansion, the better, and within 1 second if it is strong. If this is delayed, a slip occurs before the diameter expansion, or the retreat amount at the time of the diameter expansion is insufficient. After the diameter is expanded, the mandrel 10 is rotated in this state to continue winding.

Topmark flaw portion indicated by e in FIG. 2 is extended in the circumferential direction and is pulled back the tip portion S 0 of the steel strip S was slightly retracted in the arrow direction, the step caused by the tip portion is greatly alleviated. In addition, no slip occurs even after the belt wrapper retracts due to the winding effect by the diameter expansion.
