Method and device for automatically starting and ending the winding of metallic wire onto reels.

摘要

Automatic control system for the start-up and ending of the winding of metallic wire onto reels, the system being applicable to processes for the hot or cold drawing or rolling of metallic wire, which may have a round, oval, three-lobed, square, rectangular, hexagonal, etc. section, the system being fitted to the wire feed side of a machine (10) to wind metallic wire (25) on reels and comprising the following operational assemblies:a first assembly of automatic devices including in succession a unit (31) to position the wire, a gripper unit (39), a bending unit (45) and a shears unit (50), these units (31-39-45-50) being able to act on wire (25) wound on a reel (11), so as to obtain the step of ending the winding automatically,a second assembly of automatic devices including an inserter unit (58) and a clamp (67), these units (58-67) being suitable to act on one end of the wire (25) so as to obtain the step of start-up of the winding automatically, the first assembly (31-39-45-50) and the second assembly (58-67) of automatic devices cooperating in their respective operational steps with a wire-guide device (17) borne on a movable unit (21) and including means (27) to grip the wire.
