Description

Cold rolled steel winding device {Apparatus for winding of steel sheet}

The present invention relates to a winding apparatus for winding a cold rolled steel sheet in the form of a coil during the cold rolling process of steel manufacturing, and particularly to prevent end mark defects occurring during winding of the cold rolled steel sheet.

In general, a cold rolled steel sheet 1 having a series of processing steps in a steel manufacturing process is wound in a coil form by a winding device such as a tension reel 2 provided at the exit side of the pass line as shown in FIG. 1A. .

At this time, in order to wind the steel sheet on the outer circumferential surface of the tension reel (2), a process is applied by applying a predetermined tension, which causes bending of the steel sheet material at the overlapping portion of the next rotation by the thickness of the steel sheet tip. A defect called an end mark, such as a pressing mark, is generated periodically for the circumference of the steel sheet to be wound. As such, the steel sheet having the end mark is degraded in quality, resulting in dissatisfaction of the consumer.

Accordingly, various techniques for preventing end marks occurring on the surface of the steel sheet have been disclosed. For example, the winding tension is reduced in the winding equipment, or a taper is formed at the tip of the steel sheet, or a rubber sleeve for tension reel ( rubber sleeve; 2a).

However, when the winding tension is lowered, there is an advantage that the application is easy, but there is a disadvantage that the prevention effect of the end mark is extremely insignificant.

In addition, the technique of processing the taper at the tip of the product is to remove the effect of the thickness step by step cutting the steel sheet tip, the application effect is excellent, but the treatment and removal of chips generated during the tip processing and processing Necessary separately, it is difficult to process the equipment because it can cause a separate quality problem by the scattering of the chip generated.

In addition, the technique of employing a rubber sleeve on the outer circumferential surface of the tension reel is to remove the influence of the thickness step wound in the winding equipment after matching the steel sheet tip to the groove position formed in the sleeve, but the material, shape and thickness of various steel sheets The difference of the stop position of the steel plate front end occurred according to the state of, and it was difficult to employ | adopt it to the field substantially.

Accordingly, in recent years, a technique of winding a steel sheet by attaching a buffer pad as shown in FIG. 2 to a tip end portion of the steel sheet has been disclosed.

The shock absorbing pad 4 attaches an elastic material to the distal end of the coil wound in a coil shape to prevent end marks due to the thickness of the steel sheet when the steel sheet is wound on the tension reel. Such buffer pads are generally used in four types of lengths of 1000 mm, 1200 mm, 1400 mm, and 1600 mm, and generally wider than the width of the steel sheet.

More specifically, as shown in FIG. 2, as shown in FIG. 2, a pad body 4a having a predetermined thickness and surface area, and a magnet 4b embedded in the pad body to attach the pad body to the tip of the steel sheet. And a buffer member 4c attached to one end of the pad body to impart elastic force to the steel sheet.

Synthetic resin is usually used as the buffer member 4c, for example, a sponge may be applied.

However, in the related art, there is no facility for automatically supplying the shock absorber pad to the tip of the steel sheet, so it is difficult and complicated to implement the supply automation of the shock absorber pad.

Accordingly, the operator directly lifts the steel sheet to the upper portion of the winding equipment of the cold rolled steel sheet to perform the operation of inserting the shock absorbing pad, which may cause the steel sheet to be crushed in the process of lifting the steel sheet, and the shock absorbing pad may be precisely at the tip of the steel sheet. There is a problem that is not easy to insert in.

In addition, there is a risk of safety accident because the operator must be equipped with a buffer pad on the conveyor belt for transporting the cold rolled steel sheet.

The suction plate 320 is lowered by the operation of the first elevating cylinder 330 to be positioned close to the buffer pad, and then vacuum-adsorbs the selected buffer pad using a vacuum through the suction hole.

Next, after the suction plate 320 is raised again by the operation of the first lifting cylinder 330, the suction plate 320 is moved along the feeding frame 220 toward the table 110 where the steel plate is located. Then, the vacuum state of the adsorption plate 320 is cut off, and the shock absorbing pad is seated on the swing plate 421 which is preliminarily waited at the position.

At this time, the swing plate 421 is rotated forward by a predetermined angle downward by the operation of the swing member 460 to form an angle that can be easily inserted into the lower side of the steel plate. In the state where the swing plate 421 is formed to be inclined at a predetermined angle, the buffer pad is held on the swing plate by adsorbing the buffer pad using a vacuum in the rear plate 422 located behind the swing plate 421.

Thereafter, the swing plate 421 is moved forward by the second moving frame 430 and the cylinder 433, and thus the shock absorbing pad seated on the swing plate 421 is inserted below the steel plate tip.

Next, after blocking the vacuum provided to the adsorption holes 422a of the rear plate 422, the loading means 400 is moved to the rear and raised, the buffer pad is attached to the lower side of the steel sheet by magnetic force or the like.

Finally, the steel sheet is moved to the process progress direction, that is, the rear side of the table 110 with the buffer pad attached to the lower surface thereof, and wound up on a tension reel (not shown), thereby completing a series of operations.

As such, the present invention can be automated without the operator to place the buffer pad on the lower surface of the steel sheet by manual labor, thereby improving productivity and minimizing process errors.
