ABSTRACT:
A system for automatically coiling, cutting, and tying wires. The system (50) includes a plurality of wire reels (52) from which a measured length of a selected wire (114) is coiled at a coiling assembly (60). Each of the plurality of wires (54) are arranged in spaced-apart planar array across a wire select assembly (56). A control (82) selects one of the wires for coiling based upon a programmed work schedule. The end selected wire is drawn from a sensor assembly (88) on the wire select assembly by a wire feed assembly (58) and transferred to the coiling assembly. The coiling assembly winds the selected wire into a coil (402), at either a seven- or ten-inch (inside) diameter. Pinch marks previously applied to the wire or a length sensor (122) determine when a required length of the wire has been coiled. The coiled wire is then lifted from the coiling assembly by a pick and place assembly (66) and moved to one of two wire tying machines (61/62), where a tie is applied to the coiled wire so that it can be stacked on a pallet (400). A conveyor (70) conveys the pallets to an operator workstation (72) where the coiled wires are assembled into wire groups needed to make wire bundles.
