Abstract

Abstract A wire dispensing system provides for ordered dispensing and forming of wires along predetermined paths to produce cables and including automating the production of cable harnesses. A wire dispensing head is controlled to selectively dispense wires from a group of supply spools, laying the wire along predetermined paths according to the desired harness pattern configuration, cutting the wires to conform to the individual path lengths, and securing the wires at respective termination sites. The wire dispensing head includes feed tubes selectively actuated to secure the wires at the termination sites wherein movements of the dispensing head are controlled to accurately move the selected feed tubes along the paths determined by the harness pattern configuration. The desired length of an individual precoded wire is determined by optically sensing the configuration of a wire mark which controls wire pay-out by a rotatable capstan while the feed rate tension of the wires is regulated by the same capstan at a low level capable of accurately locating the wires along the wire layout paths of the cable harness wherein the tension is regulated so as not to exceed the level of wire retention at the termination sites. The termination sites include openings having resilient retaining means comprising a slit pattern in neopreme at each opening for receiving the end portion of a feed tube and retaining wires on withdrawal of the feed tube.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 108 words
A dispensing head for strand material comprising: means for supplying strand material; means for feeding said strand material including means for drivingly engaging said strand material, the feeding means includes a feed tube including means for supporting said feed tube to receive strand materiaL cut to the desired length and means for producing axial movement of the feed tube to position the end thereof for dispensing the strand material; and means for receiving and cutting the driven strand material to a desired length, said latter means including axially aligned annular members having annular opposing cutting edges for passing the strand material and slidable for cutting the strand material.
Claim 2
Dependent Claim 108 words
A dispensing head for strand material comprising: means for supplying strand material; means for feeding said strand material including means for drivingly engaging said strand material, the feeding means includes a feed tube including means for supporting said feed tube to receive strand materiaL cut to the desired length and means for producing axial movement of the feed tube to position the end thereof for dispensing the strand material; and means for receiving and cutting the driven strand material to a desired length, said latter means including axially aligned annular members having annular opposing cutting edges for passing the strand material and slidable for cutting the strand material.
Claim 3
Dependent Claim 31 words
A dispensing head according to claim 1 in which the feeding means includes a plurality of feed tubes and support means therefor are provided for receiving and dispensing said strand material.
Claim 4
Dependent Claim 40 words
A dispensing head according to claim 2 in which said dispensing head includes control means coupled to said means for drivingly engaging the strand material for selectively paying out of strand material to any selected one of said feed tubes.
Claim 5
Dependent Claim 59 words
A dispensing head according to claim 3 in which the feeding means includes a strand material guide and mark sensing means associated with the cutting means for guiding individual strands of material from said means for drivingly engaging said strand material to said cutting means and detecting marks on the strands of material for actuation of said cutting means.
Claim 6
Dependent Claim 31 words
A dispensing head according to claim 4 in which said strand material comprises insulated wire having portions along its length deformed to provide marking for sensing individual lengths of strand material.
Claim 7
Dependent Claim 33 words
A dispensing head according to claim 4 in which the strand material is marked and the sensing means is responsive to the marking to identify individual lengths of strand material from said supply.
Claim 8
Dependent Claim 33 words
A dispensing head according to claim 6 in which said control means includes circuit means responsive to the sensing means and associated with the feeding means for interrupting feeding of the strand material.
Claim 9
Dependent Claim 89 words
A dispensing head for strand material comprising: means for supplying strand material; means for feeding said strand material including means for drivingly engaging said strand material, the means for drivingly engaging said strand material includes control means for selectively engaging the individual strands for selectively feeding individual strands of material; and means for receiving and cutting the driven strand material to a desired length, said latter means including axially aligned annular members having annular opposing cutting edges for passing the strand material and slidable for cutting the strand material.
Claim 10
Dependent Claim 89 words
A dispensing head for strand material comprising: means for supplying strand material; means for feeding said strand material including means for drivingly engaging said strand material, the means for drivingly engaging said strand material includes control means for selectively engaging the individual strands for selectively feeding individual strands of material; and means for receiving and cutting the driven strand material to a desired length, said latter means including axially aligned annular members having annular opposing cutting edges for passing the strand material and slidable for cutting the strand material.
