Scrap Winder

摘要

A scrap winder is provided as part of a slitting line that creates a ribbon of scrap. The scrap winder has a moveable mandrel that exposes a grabbing portion that rotates. The grabbing portion extends outward to reveal a puller cable reel. The puller cable reel contains a retrieving cable that attaches to the start of the scrap ribbon. As the grabbing portion rotates, the scrap is brought to the grabbing portion, where the scrap is attached directly to it. The mandrel is then moved into position and the scrap can be wound around the mandrel.

1. A scrap winder for use with a slitting machine, said slitting machine having an uncoiling portion, a slitting portion, and a recoiling portion, said slitting machine adapted to generate a strip of edge trim, said scrap winder having:
a pivoting frame pivotable between a release position and a winding position, said pivoting frame having a mandrel rotatably affixed thereto and rotatable about a mandrel axis, said mandrel being tapered along its length to a tip; an inboard flange plate having a center aperture and rotatable about a driving axis, said inboard plate having a mandrel facing surface and a yoke facing surface, said yoke facing surface having pins extending therefrom; a sliding hub fixed from rotation with respect to said inboard plate and moveable axially through said center aperture between an extended position and a retracted position, said sliding hub fixed from rotation with respect to said inboard plate, said sliding hub having a front face, said retracted position defined by said front face being at a relatively close distance to said mandrel facing surface of said inboard plate, said extended position defined by said front face extending outward from said mandrel facing surface of said inboard plate, said sliding hub having a puller cable reel portion on said sliding hub located adjacent said front face, said puller cable reel portion is outward of said mandrel facing surface when said sliding hub is in said extended position, said front face of said inboard plate adapted to receive a distal end of said strip of edge trim; a yoke having a sliding hub mating portion mated with an outer diameter of said sliding hub for shifting said sliding hub axially between its said extended position and said retracted position; a driveshaft rotatable about said driving axis, said inboard plate fixed from rotation with respect to said driveshaft; and when said pivoting frame is in said winding position, said tip of said mandrel located at a relatively close position to said sliding hub and said mandrel axis substantially coaxial to said driving axis.
