Description

Strip edge debris removal device {APPARATUS FOR REMOVING ZINC-TREE IN STRIP-EDGE}

The present invention relates to a strip edge debris removal device, and more particularly to a strip edge debris removal device capable of removing the zinc (Zn) tree of the strip edge portion generated while passing through the electroplating line.

In general, the electroplating line can be divided into carouse type and horizontal cell type.

In the carousel type, current flows to both sides of the strip, which causes over-plating to the strip edge during plating, resulting in build-up.As a result of this over-plating (anode on both sides of the strip) Phenomenon that thickening of both ends of the product during winding takes place, causing a wave to occur at about 30 to 50 mm on both sides of the strip during winding.

The plated layers on both side edges of the over-plated strip are not completely attached to the strip, and when Zn (ink) powder adheres to the roll and is transferred to the strip, it may cause product defects or gather at a processing facility such as a press. There is a problem that causes a secondary failure of.

In order to solve this problem, Korean Patent Application Publication No. 2000-0014065 (2000.07.15.) Discloses a "plating steel sheet edge part polishing apparatus", and Korean Patent Registration No. 10-0762489 (2007.09.20.) Discloses a "strip buildup three-side polishing machine".

As shown in FIG. 1, this is all a technique for polishing the plating layer, in which the strip mask 2 is brought close to the strip edge portion 1 on which the zinc tree 3 is formed, thereby preventing overplating of the strip edge portion 1 and In order to prevent the strip edge portion 1 and the strip mask 2 from colliding due to meandering of the strip, the strip mask 2 is used at a distance of about 10 mm from the strip edge portion 1.

However, when the post-plating operation of 55g / m2 or more, as shown in Figure 2, the zinc tree grows, and the zinc stamping dent occurs, the zinc tree of the strip edge portion is extremely unstable, so that the zinc tree slightly Even if the touch is broken easily, even if the prior art described above is used, the brush roll must be coated and managed separately, and the life of the brush roll is extremely short, which is about one week. Dropping out causes the same problem as described above.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.

At the same time, the moving frame 800 coupled to the moving block 100 is also moved in the width direction of the strip.

Water sprayed at a constant pressure from the water spray nozzle 530 pushes the lower float 564 installed in the tube 540 at a constant pressure, and the dog sensor 568 and the magnet sensor 570 face each other. Will signal between them.

At this time, the control unit 600 determines that the cleaning unit 400 does not sufficiently approach the strip edge unit, and continuously operates the first driving unit 200. When the strip edge portion is positioned between the upper bracket 510 and the lower bracket 520 so that the water sprayed from the water spray nozzle 530 is interfered by the strip edge portion, the dog 550 is moved inside the tube 540. When the dog sensor 568 is lowered, the dog sensor 568 reaches a position which cannot be mutually opposite to the magnet sensor 570. At this time, the control unit 600 is located at a position where the cleaning unit 400 can remove the foreign substance of the strip edge portion. It is judged that it has come.
