Abstract

PURPOSE:To hold and convey wire rods surely by each piece and prevent generation of flaws in coils by forming rolled wire rods into spiral coils with a loop former, inclining these forward by prescribed angles, conveying the same and blowing a refrigerant thereto. CONSTITUTION:Finish rolled wire rods 10 are supplied to a loop former 11, by which they are looped to spiral coils 12 of prescribed diameters, and the coils are discharged successively. These are held laid down at prescribed pitches by a fore conveyor 15, and are conveyed in this state to a terminal end part where they are projected. The leading end parts of the projecting loop parts 12a are hooked by each piece with hooks 22 of a hanger conveyor 18, by which they are held and conveyed. The trailing end parts of the loop parts fall onto a bed conveyor 31 along a guide plate 40, and are held and conveyed in prescribed positions inclined forward. During this conveying, a refrigerant is supplied from a blower 44 and controlled cooling is accomplished. Next, when they arrive at the terminal end parts of the hanger conveyor 18, the hooks 22 are disengaged from the loop parts 12a by a releasing means 29, and the spiral coils 12 are fed to a stacker 42 by a relay conveyor 41.
