9 is a view for explaining a method of dismantling the slag removal unit shown in FIG. 3, and FIGS. 10 and 11 are views for explaining a method of adjusting the spacing of the blades.

On the other hand, the width and spacing of the support plates (2a) may vary according to the type and process conditions of the laser processing machine and other cutting processing machines. In this case, after separating the scraper 11 from the support frame 12, the spacer 17 may be replaced according to the width and spacing of the support plates 2a provided in the cutting machine to proceed with the slag removal operation. can

First, as shown in FIG. 9 , by separating the rotation support plates 12b and 12c from the main body 12a of the support frame 12 , the scraper 11 is separated from the support frame 12 . To this end, the rotation support plates 12b and 12c may be detachably coupled to the body 12a of the support frame 12 using bolts or other coupling members, respectively.

Next, as shown in FIG. 5 , the blades 16 and the spacers 17 are sequentially separated from the shaft 15 .

Thereafter, as shown in FIG. 10 , a second spacer 17b and a third spacer 17c having a width corresponding to the width and spacing of the supporting plates 2a of the cutting machine to proceed with the slag removal operation ), the blades 16 and the spacers 17 are sequentially rejoined to the shaft 15 in a predetermined order.

Next, as shown in FIG. 11 , the scraper 11 in which the second spacer 17b and the third spacer 17c have been replaced is recombined to the support frame 12 .

As described above, the slag removal device 1 can adjust the spacing of the blades 16 through the exchange of the spacers 17, so it can have compatibility applicable to the support plates 2a having various standards. have.

The driving member 13 is a member that provides a driving force for rotationally driving the scraper 11 . The driving member 13 is preferably configured as a motor, but is not limited thereto. The driving member 13 is fixed to the motor support plate 12d provided on one side of the support frame 12 . The rotation shaft of the driving member 13 is axially coupled to one end of the shaft 15 by a coupler 19 . Accordingly, the driving member 13 may rotationally drive the shaft 15 and the blades 16 coupled thereto.

The torque sensor 14 is axially coupled to the rotation shaft of the driving member 13 . Through this, the torque sensor 14 may measure the rotational load applied to the rotation shaft of the scraper 11 and/or the driving member 13 . The rotation load measured in this way may be input to the controller 60 .

However, the rotational load measured by the torque sensor 14 may vary depending on the amount of slag attached to the support plates 2a, the binding force of the slag, and the like. That is, as the amount of slag attached to the support plates 2a increases or the bonding force of the slag increases, the rotational load increases in proportion to this. Accordingly, if the slag removal operation is performed in a state in which the rotational load is high, a part of the slag attached to a specific portion of the support plate 2a having a high rotational load is not removed, or the blade 16, other slag removal unit The components of (10) may be damaged.

To solve this, the controller 60, when the rotational load is measured to be higher than the predetermined reference load, the slag removal operation for a specific portion of the support plate (2a), the rotational load is measured to be high, repeatedly performed two or more times. The driving member 13 of the slag removal unit 10 may be stopped to transfer the slag removal unit 10 using a transfer unit 20 to be described later, or to stop the slag removal operation.

For example, when the rotational load is measured to be higher than the first reference load, the controller 60 retracts the slag removal unit 10 using the second transfer unit 24 of the transfer unit 20 to be described later. By doing so, the slag removal operation for a specific portion of the support plate 2a having a high rotational load may be repeatedly performed two or more times.

For example, the controller 60 may stop the driving member 13 of the slag removal unit 10 to stop the slag removal operation when the rotational load is measured to be higher than the second predetermined reference load. The second reference load is preferably set higher than the first reference load, but is not limited thereto.

Meanwhile, although the torque sensor 14 has been described as being axially coupled to the rotation shaft of the driving member 13 , the present invention is not limited thereto. That is, the torque sensor 14 may be axially coupled to the shaft 15 .

Through this, it is possible to end the slag removal operation for the support plates (2a) corresponding to the first priority work reference point (R1) of the work reference points (R1, R2, R3). At the same time, the controller 60 may drive the first transferor 22 to raise the slag removal unit 10 so that the support plates 2a are drawn out from the gap between the blades 16 .

Next, as shown in Fig. 22, when the slag removal unit 10 reaches the second transfer limit point B2, the second transfer unit 24 is driven in the reverse direction to operate the slag removal unit 10. It can be retrieved to the starting point Oi or the first transfer limit point B1.

Thereafter, as shown in FIGS. 23 to 24 , the controller 60 controls the supporting plates 2a corresponding to each of the subordinate work reference points R2 and R3 among the work reference points R1, R2, and R3. The slag removal unit 10 and the transporters 20 may be driven so that the slag removal operation can be sequentially performed.
