The guide roll 70 is provided so as to support and convey the work W to be fed while idling.

Hereinafter, the operation of the present invention will be described in detail.

As shown in Figs. 4 to 7, in the rolling line of rough rolling, intermediate rolling and finishing rolling, the material W of the material of the large diameter wire rod is wound on the guide roll 70 along the conveying path P It is possible to prevent deterioration of product quality such as scratching of the surface due to friction between the guide roll 70 and the work W and to prevent worker safety accidents due to on- The material conveyance guide device 1 of the wire rolling line is as follows.

6 and 7, when the work W to be fed in the material rolling process enters the guide roll 70 between the blocks 110 through the guide block 110, The work W is supported by the guide roll 70 while the work W is supported by the guide roll 70. At this time, the work W applies a load to the guide roll 70 according to the progress speed of the work W and its size.

The load applied to the guide roll 70 by the work W is then applied to the workpiece conveying guide device of the present invention 1, the guide roll 70 is rotated clockwise when viewed from the front by the circular movement of the stand 72 about the rotary shaft 10 This is because the rotary shaft 10 is rotatably installed in the bearing block 14 fixed on the bracket 12. [

7, when the stand 72 is circularly moved as the work W advances and the rotary shaft 10 rotates in the clockwise direction, the disk means fixed to the end of the rotary shaft 10 The first and second discs 36 and 40 of the weighing means 50 integrally connected to the second disc 40 and the adjusting plate 42 are integrally rotated in a clockwise direction, The weights 52 mounted on the fixed shaft 56 are lifted clockwise, that is, leftward viewed from the front.
