Description

Foreign matter removal unit and foreign matter removal device {ALIEN SUBSTANCE REMOVING UNIT AND ALIEN SUBSTANCE REMOVING APPARATUS}

The present invention relates to a foreign matter removal unit and foreign matter removal device.

It should be noted that the content described in this section merely provides background information on the present invention and does not constitute prior art.

For continuous work on materials such as steel plates, the rear end of the first coil and the front end of the rear coil may be joined by welding. A welder wheel is placed at the top and bottom, and the upper and lower welding wheels move in the left and right directions of the steel plate to weld and join two steel plates.

The welder wheel can weld hot-dip galvanized material and hot-dip galvanized material, or hot-dip galvanized material and cold-rolled material without surface treatment.

When welding two steel plates, a strong spark is generated from the welder wheel, and foreign substances scattered around the weld area may stick to the steel plates. When foreign matter is stuck on a steel plate and passes through equipment such as various rolls, the steel plate with the foreign matter stuck on it is pressed by the various rolls, causing quality defects such as surface contamination and uneven dents in the steel plate, making normal production of finished products difficult. There is a problem.

In addition, there is a problem that the worker's workload increases and the incidence of safety accidents increases in the process of workers directly entering narrow space facilities and manually removing uneven dents and surface contamination. In addition, there are many problems such as a decrease in the operating productivity of the equipment due to interruption of operation during such maintenance work.

The close contact portion 300 prevents the foreign matter (T) removed by the removal portion 100 from passing through and escaping to the outside, and may form a fine gap through which air can pass.

The close contact part 300 may be detachably installed at the lower part of the suction part 200 so that it can be replaced.

In the foreign matter removal unit 10 of the present invention, when the removal unit 100 removes foreign matter (T) around the welding part (W), the foreign matter (T) removed from the suction part 200 and the adhesion part 300 is outside. By preventing the air from escaping and allowing the inflow of external air, the suction power of the suction unit 200 can be stably maintained, which has the effect of stably suctioning and removing the removed foreign matter (T).

Accordingly, by preventing quality defects that may occur in finished products due to foreign substances (T) adhering to the metal plate (S), the incidence of worker safety accidents that may occur during the manual removal of foreign substances (T) by workers is reduced. It can be reduced. In addition, it has the effect of improving operational productivity by minimizing operational interruption due to maintenance work.

At this time, the removed foreign matter (T) is prevented from escaping to the outside by the hood member 210 and the close contact portion 300 of the suction unit 200, and the foreign matter T inside the hood member 210 is prevented from leaving the suction unit (200). It can be removed to the suction member 230 via the suction pipe 250 by the suction force provided by the suction member 230 of 200.

The foreign matter removal unit 10 moves to the end of the welding area W, and when the removal of the foreign matter T is completed, the moving unit 20 and the foreign matter removal unit 10 can stop operating. At this time, the foreign matter removal unit 10 may be located at the end position, which is the end point where removal of the foreign matter T is completed.

For example, the above-described second sensor 21b detects the touch plate 23e to determine that the foreign matter removal unit 10 is located in the end position. When the foreign matter removal unit 10 is located in the end position, , the foreign matter removal unit 10 and the moving unit 20 can stop operating.

Thereafter, in a state where the operation of the removal unit 100 and the suction unit 200 of the foreign matter removal unit 10 is stopped, the moving unit 20 can move the foreign matter removal unit 10 back to the home position. there is.

Of course, the control unit calculates the width of the welding area (W) by calculating the moving distance, and the moving unit 20 moves the foreign matter removal unit 10 to the end of the welding area (W) to remove the foreign matter (T). can do. Thereafter, in a state in which the operation of the foreign matter removal unit 10 is stopped, the control unit may control the moving unit 20 to move the foreign matter removal unit 10 back to the home position.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and variations are possible without departing from the technical spirit of the present invention as set forth in the claims. This will be self-evident to those with ordinary knowledge in the field.
