When the guiding wire W is released Further comprising a departure prevention part (240) for allowing the detection sensor (242) to sense an electrical signal for departure,
The driving unit 200 includes:
And is fixed to the side surface of the driving drum 220 by using fixing bolts 232 provided on both sides of the fixing groove 231. The fixed Further comprising a fixture (230) for pressing and fixing the wire (W) inserted in the groove (231)
The pulley 400 includes:
A pulley frame 410 vertically installed on the upper part of the base 100 and having a spacing space therein and having a free axis 422 horizontally coupled to the spacing space;
A guide shaft 421 which is axially coupled to the free shaft 422 while being inserted into an inner spacing space of the pulley frame 410 and guides the wire W to the guide groove 421, 420);
The wire W is supported horizontally in a spaced space of the pulley frame 410 and is supported on one of the circumferential side and the lower side of the pulley drum 420, Further comprising a guide (430) for selectively changing the pull-out direction of the sheet
The release preventing part 240 includes a fixed bracket 241 which is axially coupled to one side surface of the driving frame 210 and whose rotation angle is arbitrarily adjusted and a fixed bracket 241 fixedly coupled to the other side of the shaft- Further comprising a detection sensor (242) for detecting the detachment of the wire (W) while being in contact with one surface of the wire (W)
The fixture 230 includes a friction portion 233 selectively formed to prevent damage of the wire W while preventing the wire W from sliding on the inner circumference of the fixing groove 231,
The driving motor 300 further includes a limit switch 110 connected to the driving shaft 310 to measure a length of a section of the wire W wound on the driving unit 200,
The limit switch 110 is coupled to the upper side of the base 100 adjacent to the drive motor 300. The limit switch 110 and the drive shaft 310 of the drive motor 300 are coupled to a belt 110a Further comprising the step of operating the limit switch (110) to sense the rotational speed of the drive shaft (310) in accordance with the mutual connection. delete delete delete delete
