Abstract

A system for twisting wire that includes an upper portion having a plurality of upper clamps configured to retain an upper wire end corresponding at least one wire pair. The upper portion may be selectively adjustable between a first vertical position and second vertical position. The system also includes a lower portion, disposed on vertically below the upper portion. The lower portion may include a plurality of lower clamps, each of the plurality of lower clamps may be configured to retain a first lower wire end and a second lower wire end corresponding to the at least one wire pair. The system may further include a controller configured to selectively rotate each of the lower clamps in response to instructions corresponding to a twisting program.

Claims

1. A system for twisting wire, the system comprising

an upper portion that includes a plurality of upper clamps;

the upper clamps are configured to retain an upper wire end corresponding, at least one wire pair, the upper portion is selectively adjustable between a first vertical position and second vertical position;

a lower portion, disposed vertically below the upper portion;

the lower portion including a plurality of lower clamps, each of the plurality of lower clamps is configured to retain a first lower wire end and a second lower wire end corresponding to the at least one wire pair; and

a controller configured to selectively rotate each of the lower clamps in response to instructions corresponding to a twisting program.

2. The system of claim 1, wherein the at least one wire pair includes a first wire segment and a second wire segment.

3. The system of claim 2, wherein the first wire segment includes a first upper end and a first lower end, and the second wire segment includes a second upper end and a second lower end.

4. The system of claim 3, wherein the one of plurality of upper clamps retains the first upper end, and another of the upper clamps retains the second upper end, and wherein a first lower clamp retains the first lower end and the second lower end.

5. The system of claim 1, wherein the upper portion is adjusted to the first vertical position in response to a first position signal.

6. The system of claim 5, wherein at least one lower clamp is loaded with the first lower end and the second lower end in response to the upper portion being adjusted to the first vertical position.

7. The system of claim 6, wherein the upper portion is adjusted to the second vertical position in response to a second position signal.

8. The system of claim 7, wherein when the upper portion is adjusted to the second vertical position, the controller initiates rotation of each of the lower clamps.

9. The system of claim 1, further comprising a pre-load device disposed adjacent to the upper portion, the pre-load device being configured to receive a plurality of upper ends corresponding to at least one other wire pair.

10. The system of claim 9, wherein the pre-load device is configured to transfer the at least one other wire pair from the pre-load device to the upper portion in response to the pre-load device being closed onto the plurality of upper clamps.

11. A system for twisting wire, the system comprising

an upper portion that includes a plurality of upper clamps;

the upper clamps are configured to retain an upper wire end corresponding at least one wire pair, the upper portion is selectively adjustable between a first vertical position and second vertical position;

a lower portion, disposed vertically below the upper portion;

the lower portion including a plurality of lower clamps, each of the plurality of lower clamps is configured to retain a first lower wire end and a second lower wire end corresponding to the at least one wire pair;

a wire guide disposed between the upper portion and the lower portion;

the wire guide is configured to guide the at least one wire pair between the upper portion and the lower portion;

a pre-load device disposed adjacent to the upper portion;

the pre-load device is configured to retain upper wire ends corresponding to at least one other wire pair, the pre-load device is adjustable between an open and a closed position; and

a controller configured to selectively rotate each of the lower clamps in response to instructions corresponding to a twisting program.

12. The system of claim 11, wherein the at least one wire pair includes a first wire segment and a second wire segment.

13. The system of claim 12. wherein the first wire segment includes a first upper end and a first lower end, and the second wire segment includes a second upper end and a second lower end.

14. The system of claim 13, wherein the one of plurality of upper clamps retains the first upper end, and another of the upper clamps retains the second upper end, and wherein a first lower clamp retains the first lower end and the second lower end.

15. The system of claim 11, wherein the upper portion is adjusted to the first vertical position in response to a first position signal.

16. The system of claim 15, wherein at least one lower clamp is loaded with the first lower end and the second lower end in response to the upper portion being adjusted to the first vertical position.

17. The system of claim 16, wherein the upper portion is adjusted to the second vertical position in response to a second position signal.

18. The system of claim 17, wherein when the upper portion is adjusted to the second vertical position, the controller initiates rotation of each of the lower clamps.

19. The system of claim 11, further comprising a vertical wire storage rack that is configured to store a plurality of wire segments prior to the wire segments being loaded into the upper and lower portions.

20. The system of claim 11, further comprising a table that includes a plurality storage areas, wherein the storage areas are configured to receive twisted wire pairs that are unloaded from the upper and lower portions.
