Abstract

A control device according to some embodiments of the disclosure includes one or more motors directed by the control device to form whip(s) from a length of a cable by causing the cutting of the cable in accordance with specifications based at least in part on whip information. An interface communicates the whip information between the control device and a user device.

First claim

What is claimed is:

1. A machine for fabricating a whip from a cable, the cable having an outer jacket and one or more conductors enclosed by the outer jacket, the whip having a portion of the outer jacket and the one or more conductors therein, the machine comprising:
an input into which the cable is fed into the machine and an output through which the whip exits the machine, wherein a cable travel space is defined along a longitudinal axis between the input and the output;
a notching saw downstream of the input;
a first motor operatively connected to the notching saw, wherein the notching saw is configured to be moved between a first position and a second position by the first motor, wherein the notching saw is in contact with the outer jacket of the cable in the first position, and wherein the notching saw is not in contact with the outer jacket of the cable the second position;
a second motor operatively connected to the notching saw, wherein the second motor is configured to drive the notching saw, wherein activation of the first and second motors causes the notching saw to cut the outer jacket of the cable in a direction parallel to or substantially parallel to the longitudinal axis of the cable to form a notch in the cable when the notching saw is in the first position;
a cutting tool downstream of the notching saw and upstream of the output, the cutting tool having at least one cutting edge;
at least one motor operatively connected to the cutting tool, wherein activation of the at least one motor operatively connected to the cutting tool causes the at least one cutting edge of the cutting tool to completely cut the outer jacket and the conductors of the cable from a remainder of the cable during the same cutting motion and in a direction transverse to the longitudinal axis when the at least one cutting edge of the cutting tool passes through the cable travel space to form the whip; and
a controller configured to receive whip information corresponding to the whip to be fabricated, the controller operatively coupled to the motors and configured to control operation of the motors based at least in part on the whip information corresponding to the whip to be fabricated, wherein in response to receipt of the whip information the controller causes:
a. the first motor to move the notching saw into the first position when the cable is in a first location,
b. the second motor to actuate the notching saw to cut a first longitudinally extending notch having a length in the outer jacket of the cable,
c. the first motor to move the notching saw into the second position,
d. the first motor to move the notching saw into the first position when the cable is a second location which is spaced from the first location,
e. the second motor to actuate the notching saw to cut a second longitudinally extending notch having a length in the outer jacket of the cable, the second notch being longitudinally aligned with the first notch,
f. the first motor to move the notching saw into the second position, and
g. the least one motor operatively connected to the cutting tool to actuate the cutting tool to completely cut the outer jacket and the conductors of the cable to separate the whip from the remainder of the cable when the cable is in a third location.

2. The machine of claim 1 , wherein the whip information includes whip length, lead length, and tail length.

3. The machine of claim 1 , wherein the whip information is received based at least in part on one or more of a received user input, information received from an external computing device through wireless or wired technology, data automatically extracted from architectural drawing models using an application, information extracted from a spreadsheet, and one or more saved files.

4. The machine of claim 1 , wherein the motors are coupled wirelessly or through wired technology to one or more external devices.

5. The machine of claim 1 , further comprising
a feed roller, and a motor operatively connected to and configured to rotate the feed roller in a reverse direction to back tension the cable, wherein the controller is further configured to control operation of the motor operatively connected to the feed roller based at least in part on the whip information.

6. The machine of claim 1 , further including at least one of a coiling assembly configured to wind the whip into a coil after the cable is cut and secure the coil with a tie, and a labeler assembly configured to label the whip after the cable is cut.

7. The machine of claim 6 , wherein the labeler assembly is mounted to the machine before or after the machine or mounted within a cabinet.

8. The machine of claim 1 , further comprising a pad downstream of the input and operatively coupled to the first motor, wherein a first activation of the first motor causes the pad and the notching saw to move into the first position, and a second activation of the first motor causes the pad and the notching saw to move into the second position.

9. The machine of claim 1 , wherein the at least one motor operatively connected to the cutting tool includes a first motor which causes the cutting tool to move into the cable travel space, and a second motor which causes the at least one cutting edge of the cutting tool to completely cut the outer jacket and the conductors of the cable in a direction transverse to the longitudinal axis.

10. The machine of claim 1 , further including an interface operatively coupled to the controller, the interface configured to receive whip information and communicate information to the controller.

11. The machine of claim 1 , further comprising
a feed roller downstream of the input and upstream of the notching saw; and
a motor operatively connected to the feed roller, the motor operatively connected to the feed roller being configured to rotate the feed roller in a first direction to advance the cable along the cable travel space from the input toward the output under the direction of the controller, and further configured to rotate the feed roller in a reverse direction to advance the cable toward the input to back tension the cable under the direction of the controller.

12. The machine of claim 11 , further comprising
a pad downstream of the input and operatively coupled to the first motor; and
wherein
a first activation of the first motor causes the pad and the notching saw to move into the first position, and a second activation of the first motor causes the pad and the notching saw to move into the second position.

13. The machine of claim 1 , wherein multiple whips are formed along the length of the cable.

14. The machine of claim 13 , wherein the whip information includes whip length, lead length, tail length, and number of whips.

15. The machine of claim 1 , wherein the third location is spaced from the second location.

16. A machine for fabricating a plurality of whips from a single cable, the cable having an outer jacket and one or more conductors enclosed by the outer jacket, each whip having a portion of the outer jacket and the one or more conductors therein, the machine comprising:
an input into which the cable is fed into the machine and an output through which the whips exit the machine, wherein a cable travel space is defined along a longitudinal axis between the input and the output;
a notching saw downstream of the input;
a first motor operatively connected to the notching saw, wherein the notching saw is configured to be moved between a first position and a second position by the first motor, wherein the notching saw is in contact with the outer jacket
