The wire rope is wound around the winch drum and the looper car connected to the wire rope pulls the strip into the loop arrangement or the strip is withdrawn from the roof arrangement.

By the way, the conventional structure of the wire rope is moved along the longitudinal direction of the winch drum as the wire rope moves to the left and right according to the winding and unwinding position of the wire rope for the winch drum as the looper travels. Due to the movement of the center, the force of the central axis of the wire rope that pulls the looper car moves from time to time, resulting in plate pull and wave when storing the strip.

As a result, edge side trimming is performed to meet the demand width.The side trimming causes the plate to fall out of the string roll control range due to plate tilting, resulting in excessive production of strip edge overtrimming as well as falling production rate and other factors such as production equipment trouble. It is becoming.

Accordingly, the present invention has been made in order to solve the above problems, to minimize the center of gravity of the movement of the looper car wire rope when the wire rope of the winch drum is wound or unwound when driving the looper car to prevent meandering It is an object of the present invention to provide a wire rope winding apparatus of a looper facility.

In addition, the present invention can prevent the plate pull and the wave generation of the strip by changing the tension of the central axis of the looper by giving the angle of the sibu roll in advance by recognizing the plate pull and wave generation caused by the material strip width and poor shape in advance. It is yet another object to provide a wire rope winding apparatus of a looper installation.

In order to achieve the object as described above, the present invention, the guide portion for reciprocating the wire rope in the longitudinal direction of the winch drum to proceed in a direction perpendicular to the winch drum, and the looper car according to the wire rope position of the guide portion It maintains the force transmitted to the uniform to prevent the holding of the looper car.

Therefore, the wire rope can be accurately wound along the winch drum and the wire rope can pull the coil car at the same position by the operation of the retainer despite the change of the position of the wire loafers.

And the buffer spring 28 for cushioning the impact between the wire rope 130 and the guide roll 24 is elastically installed between the moving member 22 and the support bracket 23.

In addition, a frame 29 protrudes in front of the support bracket 23, and a guide rail 30 is installed in the same direction as the transfer screw 20 on the frame 29, and a sliding member is provided on the guide rail 30. (31) is movably installed, and the guide roll (32) for guiding the wire rope 130 to the guide roll (24) is further provided on the sliding member (31).

Accordingly, the wire rope 130 having passed through the holding part may be guided to the guide roll 24 through the guide roll 32 and then wound vertically on the winch drum 140.

The drive means is, for example, the drive motor 33, the rotation shaft of the drive motor 33 and the sprocket wheel 34 is installed at the tip of the transfer screw 20 and the chain 35 connecting each sprocket wheel 34. The present invention is not particularly limited thereto, and it will be sufficient if the driving force can be transmitted to the transfer screw 20 to reversely rotate the transfer screw 20.

On the other hand, the holding part is to prevent the meandering of the looper car 120 by always transmitting the same force to the looper car 120 regardless of the center movement of the wire rope 130, as shown in Figure 4 the base member 40 and the base guide roll 41 is rotatably installed on the upper portion of the base member 40 to guide the wire rope 130 to the guide portion and horizontally installed in front of the base member 40. Rotating shaft 42, the rotating member 43 is installed so as to be rotatable via the rotating shaft 42, the upper portion of the rotating member 43 by the bracket 44 is horizontally installed through the wire rope 130 And a pivoting roll 45 for guiding the vertical guide roll 41 to the vertical guide roll 41 and a pivoting means for rotating the pivoting member 43.

In addition, a position sensor 50 for detecting a rotation angle of the rotation member 43 is further provided below the rotation member 43.

The rotation means is a screw jack 46 axially coupled to one side end of the rotation member 43, the operating motor 47, the rotating shaft of the operating motor 47 and the screw jack 46 It is installed between the and includes a gear box 48 for converting the rotational force of the operating motor 47 to the linear motion of the screw jack 46.

Accordingly, by rotating the rotating member 43 in accordance with the position of the wire rope 130 by the guide portion it is possible to maintain the tension of the wire rope 130 as it is.

Hereinafter, the installation structure of the present invention in more detail as follows.

As shown in FIG. 4, a sibu roll 45 and a vertical guide roll 41 of a secondary role are provided to maintain the central tension of the looper car 120 so that the looper car 120 can be tilted. The shibu roll 45 is connected to the base member 40 which can be rotated by ± 30 degrees to advance the state of the strip 100 and the plate tilt in the horizontal looper facility 110 in CPC (Center.Position.Control). Sensing and moving the rotation angle of the shibu roll 45 as much as the plate tip to give a change of the wire rope 130, the rotation angle of the shibu roll 45 to the position sensor 50 to know the movement amount and check its position Is detected.

The guide part for uniform winding of the wire rope 130 is a device for uniformly winding the wire rope 130 angled by the shibu roll 45 to the winch drum 140 groove and the groove of the winch drum 140. The drive motor 33 drives the feed screw 20 by receiving the motor PLG rotation speed.

By moving the sprocket wheel 34, the movable member 22 moves from left to right or right to left and is wound and unwound evenly in the groove of the winch drum 140 whenever the rotation angle of the wire rope 130 is changed. The guide roll 24 is located in the center.

There is a support bracket (23) for holding and assisting the guide roll 24 on both sides, and the shock spring that can absorb the external shock and the external shock and offset the rocking and tension of the wire rope 130 when the guide roll 24 rotates 28 is inserted and connected between the support bracket 23 and the moving member 22.

On the other hand, for uniform winding of the wire rope 130, the movement angle of the shibu roll 45 is limited to ± 0 ~ ± 30 degrees, the wire movement amount is ± 0 ~ ± 60mm, the strip 100 movement amount ± 0 ~ It is desirable to limit ± 40mm.

Looking at the reason for this limitation, when the movement angle of the shibu roll 45 is more than ± 30 degrees, the movement amount of the strip 100 is more than ± 40mm wire rope of the winch drum 140 during the run of the looper car 120 ( When the 130 is wound or unwound, the movement of the center of the force of the looper car 120 and the wire rope 130 is excessive, so that it is impossible to work with waves and damage to the edges of the material strip 100 due to meandering. Work is impossible due to plate deflection due to poor shape.

The reason for limiting the amount of wire movement to ± 60 mm is that the wire rope 130 is unevenly wound around the winch drum 140 when it is maintained at ± 60 mm or more, which causes another facility failure. This causes the strip 100 to tip left and right, causing ear damage and plate breakage.

In this case, the amount of wave generation at the edge portion of the strip 100 is generally not enough to be applied to both edge portions of the strip 100 as long as it is possible to visually check a state in which both edge portions are not coated and partially uncoated at the time of insulation coating. If it is not severe, if the edge coating is good, it is judged as not generated and classified.

In addition, the degree of damage to the ear is finely generated at both edges of the strip 100, but the coating is weak when the damage to the coater roll is weak. If this defect is severe, it is defined as unworkable when it is severe enough to break the blade by intervening with the equipment before passing the cotter roll.

The progress of the work with such limited conditions is shown in Table 1 below.

However, the width between the sibu roll 45 and the guide roll 24 is 10m, and the line speed 125mpm strip 100 thickness 0.5 with the width between the guide roll 24 and the winch drum 140 set to 2m, respectively. T, annealing and decarburizing of non-oriented electrical steel sheet 1120mm in width through the looper facility 110, which is the main equipment, after the insulation coating is wound in the form of coils during the strip 100 edge wave generation and ear damage And workability were shown, respectively.

As described above, in the case of Inventive Examples 1 and 2, the amount of wave generation at both edge portions of the strip 100 and the occurrence of ear damage were not generated, and the workability was found to be good.

On the other hand, in Comparative Examples 1, 2, 3, and 4, the amount of wave generation at both edges of the strip 100 and the occurrence of ear damage are all inadequate due to normal, severe, or unworkable, and the workability is moderate, severe, and unworkable. It can be seen that it is inappropriate.

The action of the wire rope 130 winding device of the present embodiment configured as described above is as follows.

In order to perform the continuous work without the center line while the welding part removal work and the product coil weight cutting work at the exit side, supplying the strip 100 to the horizontal looper facility 110 and storing the strip 100 again. In order to minimize the change in the center tension of the looper car 120 generated in the process, the angle of the sibu roll 45 is adjusted to prevent the center of the wire rope 130 from moving during the driving of the looper car 120 and always the looper car ( The uniform force of the 120 is applied, and a constant tension is always applied to the center of the looper car 120 during the reciprocation of the looper car 120 to prevent meandering of the strip 100.

In addition, by using the plate tilting action for the center movement of the looper car 120 according to the winding position of the wire rope 130 of the existing winch drum 140, the state of the strip 100 and the plate tilting being progressed on the horizontal looper. The position is sensed by the CPC (Center.Position.Control) and the operating motor 47 is driven by the compensation position value to move the screw jack 46 engaged through the gearbox 48.

According to the linear movement of the screw jack 46, the rotating member 43 connected to the upper end of the screw jack 46 is rotated about the rotating shaft 42, so that the sheet roll 45 on the upper portion of the rotating member 43 is wired. Pull in the direction of rotation.

At this time, by showing the angle in the opposite direction to the plate roll moving direction of the shibu roll 45 will be able to prevent the meandering of the strip 100 by changing the central axis of the wire pulling the looper car 120.

In this case, the sheet roll 45 is automatically controlled according to the shape and width of the strip 100 to prevent the meandering of the strip 100 and the position sensor which knows the rotation angle movement amount of the sheet roll 45. There is a sibu roll 45 position can be checked at any time.

Then, the wire changed by the shibu roll 45 is guided by the vertical guide roll 41 and then proceeds between the guide rolls 24 of the guide part in a state where the lower portion is supported by the guide roll 32.

In this state, the drive motor 33 rotates the sprocket wheel 34 by receiving the PLG rotational speed of the winch drum 140 motor, and the transfer screw connected to the sprocket wheel 34 via a chain 35. 20 is reversely rotated, and the movable member 22 engaged with the transfer screw 20 reciprocates along the transfer screw 20.

As the moving member 22 moves from side to side, the wire rope 130 between the guide rolls 24 installed on the support bracket 23 is guided along the winch drum 140 so that the winch drum 140 groove is normally not entangled. Coiled in the groove.

According to the wire rope winding apparatus of the looper equipment according to the present invention as described above, according to the wire rope winding position of the existing winch drum, which is a problem of the horizontal looper equipment with a narrow space, and prevents the plate tilting for the center movement of the looper car In addition, it is possible to prevent the meandering of the strip by inducing the center tension movement of the wire rope by grasping in advance the state of the strip and the position of the plate pull that are going on the horizontal looper.

In addition, it is possible to minimize plate tilting and wave generation when storing strips, and thus, it is possible to prevent the fall of production error rate and the reduction of work rate such as occurrence of outage trouble by preliminary strip edge trimming as well as good width management in exit side trimming.
