Disclosed is a tension reel siggement gripper device for winding a coil for preventing the occurrence of buckling of a coil to be wound.

In general, the SENDZIMIR REVERSE MILL facility is a process for pickling the raw materials supplied from hot-rolled steel by the strength adjustment and processing process (APL process) and then rolling it into products of thickness and shape required by the customer. And is rolled in 5 passes or 6 passes according to a pass schedule for each size.

The rolled product is withdrawn from the tension reel and transferred to the next process.

However, when the rolled product is pulled out from the tension reel, the initial strip is fixed by the operation failure of the gripper which fixes the strip so as to maintain the proper tension in order to prevent the inner diameter from loosening and to prevent skewing during the initial winding. The coil whose coil diameter has been lost due to the advance of the coil vehicle (coil car) and which has lost the winding force is buckled.

Accordingly, when the coil is buckled, the gripper needs to be replaced with a new one, and the production cost is reduced and the replacement cost is incurred.

Provided is a tension reel sig- nement gripper device for winding a coil that can minimize buckling of a wound steel coil coil by minimizing deformation of a gripper for winding the coil.

A tensioner reel segment gripper device for winding a coil includes a gripper bar inserted into an assembly groove formed along a longitudinal direction of a tension reel for installing a gripper and lifted by a lower bar spring to fix an end of the steel plate; A guide installed at an upper portion of one side of the gripper bar and assembled so that an end of the steel plate can be inserted through a space formed by the gripper bar; And a row guide in the form of a segment that is installed along the gripper bar in a state of being in contact with the other side of the gripper bar to thereby support the gripper bar.

The row guide may be divided into two or more pieces, and each unit row guide may be assembled to an assembly groove of the tension reel.

The gripper bar may have a structure symmetrical with respect to the center of the gripper bar.

The gripper bars may be integrally formed and assembled in a bidirectional compatible manner.

The gripper bar further includes a stopper inserted into an empty space at an end of the gripper bar in a state where the gripper bar is installed in an assembly groove of the tension reel.

The gripper bar further includes a support member for fixing the gripper bar to the assembly groove of the tension reel with the gripper bar fixed to the lower portion thereof.

The gripper bar may have a structure in which a coupling groove for assembling the support member is formed at a lower portion thereof.

The gripper bar may have a sloped surface contacting the end of the steel plate.

The stopper may be a bidirectional compatible structure that is assembled to one end or both end portions of the gripper bar regardless of the assembling direction, with a space formed therein.

According to the present apparatus, the shape of the tension reel segment gripper is improved to minimize the deformation of the gripper, thereby preventing the occurrence of buckling of the coil of the electric steel plate, thereby improving the quality of the coil product.

In addition, it is possible to prevent the occurrence of buckling of the steel plate coil product, for example, the electric steel plate coil product, thereby improving the productivity and workability, preventing accident of the equipment for winding the electric steel plate into a coil, The component compatibility can be improved.
