Abstract
Scrap material cut by a shear is gripped by a vertically and transversely movable scrap-gripping and conveying mechanism which feeds the strip generally parallel to the back side of the shear into a pinch roll drive. The scrap is then fed into a slot of a scroll spindle. The spindle is rotated, and the scrap wraps around the spindle into a compact cylindrical package. Once the scrap is entirely rolled on the spindle, the spindle is retracted by a cylinder, and the scrap is pushed off the end of the spindle and falls into a storage area.

In a conveying system for a shear having an elongated shear blade and a conveyor for moving cut metal in a preselected direction from the shear, a scrap scroller for moving strips of scrap metal cut from the shear away from the conveyor and compacting the strips, the scroller comprising:
- a scroller frame located adjacent the shear;
- a spindle rotatably mounted in the frame adjacent and offset to one side of the shear blade for rotation about an axis generally transverse to the shear blade and parallel to the preselected conveying direction, said spindle including a strip-receiving portion;
- means for moving the strip parallel and adjacent to the shear blade;
- guide means for directing one end of the metal strip into the receiving portion;
- means for rotating the spindle to wind the strip in a compact scroll onto the spindle;
- and
- means providing relative axial movement between the scroll of metal and the spindle for removing the scroll from the spindle.
A method for handling strips of scrap metal cut by an elongated shear, the method comprising:
- (a) gripping one end of a strip of scrap material as it is being cut
- (b) moving the strip generally parallel to the elongated shear
- (c) directing one end of a strip of scrap material into contact with an elongated spindle having an axis of rotation generally perpendicular to the shear and located at one end of the shear;
- (d) rotating the spindle about the axis of rotation to wind the strip onto the spindle and thereby draw said strip in the direction of said one end of the shear;
- and
- (e) removing the wound strip from the spindle adjacent said one end of the shear.
A method for handling a strip of scrap material cut from a sheet of material by a metal shear having a side frame and an elongated cutting blade having one end located adjacent the side frame, the method comprising the steps of:
- (a) gripping the strip of material as the strip is severed from the sheet;
- (b) moving the strip of material closely adjacent the cutting blade in a direction generally parallel to the longitudinal axis of the blade toward the side frame of the shear;
- and
- (c) rolling the strip of material into a compact scroll adjacent the side frame.
In a conveying system for a shear, scrap-handling structure for removing and compacting narrow strips of material cut by the shear, each strip having a major axis extending in a preselected direction generally parallel to the shear, said scrap-handling structure comprising:
- a scrolling mechanism located closely adjacent the shear, said mechanism including a rotatable spindle having an axis of rotation offset to one side of the shear and generally perpendicular to the axis;
- means for moving a strip of material into contact with the spindle;
- and
- means rotating the spindle for wrapping the strip onto the spindle in a compact scroll and thereby removing the strip from the shear.
