Title:
APPARATUS AND METHODS FOR WIRE-TYING BUNDLES OF OBJECTS
Document Type and Number:
WIPO Patent Application WO2001068450
Kind Code:
A3
Abstract:
Apparatus and methods for wire-tying one or more objects. A wire accumulating and feeding mechanism feeds the wire axially through the hollow axle of an accumulator drum and then out to a drive wheel. The wire is wrapped around the periphery of the drum to accumulate the wire during tensioning. A wire gripping mechanism is a simple, economical device including a gripper block (322) having a wire receptacle (321) formed therein, an opposing wall (333) positioned proximate the wire receptacle, and in one embodiment a tapered gap (325) formed in the gripper block proximate the wire receptacle and opposite from the opposing wall, and a gripper disc (326) mounts in a gripper release lever (324) constrained to move within the tapered gap and frictionally engageable with the length of wire disposed within the wire receptacle, the gripper disc being driven into the tapered gap by frictional engagement with the length of wire and pinching the length of wire against the opposing wall when the drive motor is operated in the tension direction. In an alternative embodiment the gripper release lever pinches the wire against the gripping wall. In another embodiment, an apparatus includes a track assembly including multiple modular segments forming a corner of the track. In yet another aspect, a twisting assembly includes a twist motor coupled to a rotatable twist axle having a plurality of cams attached thereto, the primary functions of the twisting assembly being cam-actuated.
