Abstract
Abstract An improved apparatus for automatically producing cable with terminals crimped thereto is disclosed which includes a cable storing section, for storing various kinds of cables, a cable selecting section for selecting a required cable, a cable measuring and cutting section, a cable sheath stripping section for removing insulative sheath at the foremost end parts of the cable, a terminal crimping section having a plurality of terminal pressure connecting machines arranged in line along a conveyor, and a control circuit. The control circuit automatically controls selection of kinds of cables and terminals and their working conditions at every time when operations are achieved in each of the sections. The cable measuring and cutting section is provided with a direct measuring mechanism in which a distance of movement of the measuring head is measured while it is stretched under the effect of tension. The cable sheath stripping section is preferably provided with a stripping length adjusting mechanism which serves to adjustably determine the length of naked wire portion of the cable at the foremost end parts thereof with insulative sheath removed therefrom.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
206 words
An apparatus for automatically producing cable with terminals crimped thereto comprising a cable storing section for storing a plurality of various kinds of cables each at a position predetermined in accordance with its kind, a cable selecting section for selectively taking a certain cable from a selected one of the group of cables stored in said cable storing section, a cable measuring and cutting section for measuring a predetermined extended length of a cable selected in said cable selecting section and cutting it to a preselected measured length, a cable sheath stripping section in which insulative sheaths at the cut ends of the selected cable are stripped, a terminal crimping seciton including a plurality of terminal crimping machines and feed means for different terminals and each having a crimp height adjusting mechanism incorporated therein, and a control circuit controlling said cable selecting section, said cable measuring and cutting section, said sheath stripping section and said terminal crimping section for selecting in sequence the desired kind of cable to be processed, measuring and cutting the appropriate length of the selected cable, stripping the ends thereof, and selecting the appropriate preselected terminal for each of said ends and attaching by crimping the selected terminals to the stripped ends.
Claim 2
Independent Claim
206 words
An apparatus for automatically producing cable with terminals crimped thereto comprising a cable storing section for storing a plurality of various kinds of cables each at a position predetermined in accordance with its kind, a cable selecting section for selectively taking a certain cable from a selected one of the group of cables stored in said cable storing section, a cable measuring and cutting section for measuring a predetermined extended length of a cable selected in said cable selecting section and cutting it to a preselected measured length, a cable sheath stripping section in which insulative sheaths at the cut ends of the selected cable are stripped, a terminal crimping seciton including a plurality of terminal crimping machines and feed means for different terminals and each having a crimp height adjusting mechanism incorporated therein, and a control circuit controlling said cable selecting section, said cable measuring and cutting section, said sheath stripping section and said terminal crimping section for selecting in sequence the desired kind of cable to be processed, measuring and cutting the appropriate length of the selected cable, stripping the ends thereof, and selecting the appropriate preselected terminal for each of said ends and attaching by crimping the selected terminals to the stripped ends.
Claim 3
Dependent Claim
39 words
An apparatus as defined in claim 1, wherein the cable measuring and cutting section includes a direct measuring mechanism in which a distance of extension of a selected cable is measured while it is kept in the stretched state.
Claim 4
Dependent Claim
19 words
An apparatus as defined in claim 1, wherein the cable sheath stripping section includes a stripping length adjusting mechanism.
Claim 5
Dependent Claim
36 words
An apparatus as defined in claim 1, wherein the cable storing section comprises a plurality of hollow cylindrical packs having open upper ends and each receiving a bundle of cable in the form of a coil.
Claim 6
Dependent Claim
33 words
An apparatus as defined in claim 4, wherein the cable selecting section includes a bed having transversely spaced apart areas thereon each adapted to receive cable from a respective one of the bundles.
Claim 7
Dependent Claim
66 words
An apparatus as defined in claim 1, further including an electrical communication confirmation testing device interposed between the cable sheath stripping section and the terminal crimping section for testing to determine that the cable is properly stripped in the cable sheath stripping section, the control circuit being operative to disable the subsequent terminal crimping section operation in the event the stripping has not been properly completed.
Claim 8
Dependent Claim
36 words
An apparatus as defined in claim 6, wherein the control circuit further reprograms a new cable operation for the rejected cable so as to produce the desired number of cables of each of the respective kinds.
Claim 9
Dependent Claim
37 words
An apparatus as defined in claim 1, further including a terminal checking section positioned downstream of the terminal crimping section for testing to ensure that terminals have been properly attached to the ends of the selected cable.
Claim 10
Dependent Claim
43 words
An apparatus as defined in claim 8, wherein the control circuit further includes means for reprogramming a new selected cable in the event the terminal attachment test is not successfully passed so as to produce the desired number of cables of each type.
Claim 11
Dependent Claim
60 words
An apparatus as defined in claim 1, wherein the cables are moved along a predetermined path from the cable sheath stripping section and the terminal crimping section and the means for stripping the cable sheath in the cable stripping section and the means for attaching terminals in the terminal crimping section are all disposed at one side of said path.
Claim 12
Dependent Claim
46 words
An apparatus as defined in claim 10, further including means between the cable measuring and cutting section and the cable sheath stripping section for folding the cut cable back upon itself so that the cut severed ends are disposed at the one side of the path.
