Method and apparatus for removing wires from a bale
View Patent ↗A method and apparatus for removing wires from a bale includes a conveyor system for moving one or more bales and a de-wiring station positioned adjacent the conveyor system. The de-wiring station includes a robot with an end tool. A bale that is bound by one or more wires is transferred by the conveyor system to a position proximate the de-wiring station. The robot with end tool moves to sense the location of the wires, cut the wires, collect the wires and deposit the wires in a collection hopper.
1. An apparatus for removing wires from a bale comprising a robot having a full range of movement in three planes; an end tool positioned on the distal end of the robot, said end tool including a housing having (1) a visioning system with at least one camera for locating the wires on the bale and (2) a wiring cutting tool, wherein, upon the visioning system locating the wires, the robot places the cutting tool proximate the wires, and the cutting tool clips the wires, thereby allowing the wires to be removed from the bale.
2. The apparatus of claim 1 wherein said housing includes at least two sensors for locating the wire and instructing the robot to position the cutting tool proximate the wire.
3. The apparatus of claim 2 wherein the end tool further includes at least two bumper pads, each bumper pad located proximate the sensor where in the bumper pads engage the wire and hold the wire against the bale as the cutting tool clips the wire.
4. The apparatus of claim 1 wherein the cutting tool is retractable within the end tool when not in use clipping wires.
5. The apparatus of claim 1 wherein the end tool further includes a wire collecting spindle for removing the wires from the bale, said spindle being rotatable in a first direction to collect the clipped wires and in a second direction to disgorge the clipped wires from the spindle.
6. The apparatus of claim 5 wherein said wire collecting spindle has a circular pipe-like casing for receiving said wire while rotating in said first direction.
7. The apparatus according to claim 6 further including a plurality of guide pins adjacent said spindle.
8. The apparatus of claim 5 wherein said pipe-like casing has a plurality of slots at a lower most portion of said spindle.
9. An apparatus for removing wire from bales comprising a robot having a full range of movement in three planes; an end tool positioned on the distal end of the robot, said end tool including housing having (1) a visioning systems with at least one camera for locating the wire on the bale, (2) a wire cutting tool, and (3) at least two bumper pads, said bumper pads positioned to engage the wire and hold the wire against the bale as the cutting tool clips the wire, wherein, upon the visioning system locating the wire, the robot places the cutting tool proximate the wire, and the cutting tool clips the wire, thereby allowing the wire to be removed from the bale, a wire collecting spindle for removing the wire from the bale, said spindle being rotatable in a first direction to collect the clipped wire and in a second direction to disgorge clipped wire from the spindle.
10. The apparatus of claim 9 wherein the cutting tool includes at least two sensors for locating the wire and instructing the robot to position the cutting tool proximate the wire.
11. The apparatus of claim 9 wherein the cutting tool is retractable within the end tool when not in use clipping wires.
