Abstract

A carrier for supporting a yarn to be used by a braiding machine, has: a spool carrying the yarn; a motor drivingly engaged to the spool; at least one sensor for producing data about a condition of the yarn in the spool; and a controller operatively connected to the motor and to the at least one sensor, the controller having a processor and a computer-readable medium operatively connected to the processor and having instructions stored thereon executable by the processor for: receiving said data from the at least one sensor; determining operation parameters of the motor based on the received data; and operating the motor per the determined operation parameters to create the desired tension in the yarn.

First claim

What is claimed is:

1. A carrier for supporting a yarn to be used by a braiding machine, comprising:
a spool carrying the yarn;
a motor drivingly engaged to the spool;
at least one sensor for producing data about a condition of the yarn in the spool; and
a controller operatively connected to the motor and to the at least one sensor, the controller having a processor and a computer-readable medium operatively connected to the processor and having instructions stored thereon executable by the processor for:
receiving said data from the at least one sensor;
determining operation parameters of the motor based on the received data; and
operating the motor per the determined operation parameters to create the desired tension in the yarn, including rewinding the yarn around the spool with the motor to create the desired tension.

2. The carrier of claim 1 , wherein the receiving of the data includes receiving data about a quantity of yarn remaining around the spool.

3. The carrier of claim 2 , wherein the at least one sensor is a potentiometer engaged to an arm pivotably mounted to a housing of the carrier supporting the spool, a distal end of the arm biased in abutment against the yarn of the spool, the distal end of the arm movable toward the spool as the yarn is consumed, the receiving of the data about the quantity of the yarn includes receiving a signal from the potentiometer indicative of the quantity of the yarn remaining.

4. The carrier of claim 1 , wherein the determining of the operation parameters includes determining a torque generated by the motor.

5. The carrier of claim 4 , wherein the determining of the torque includes determining a current to be supplied to the motor to achieve the determined torque.

6. The carrier of claim 1 , wherein the receiving of the data includes receiving data about an angular position of the motor.

7. The carrier of claim 6 , comprising an encoder operatively coupled to the motor and to the controller, the receiving of the data includes receiving the angular position of the motor from the encoder.

8. The carrier of claim 1 , comprising a battery operatively connected to the controller and to the motor, the battery located within a housing of the carrier, the spool rollingly engaged to the housing.

9. The carrier of claim 1 , wherein the controller is further configured for transmitting data about the tension in the yarn.

10. The carrier of claim 1 , wherein the spool is disposed around the motor, a shaft of the motor supported by two arms protruding from a housing, the spool rollingly engaged to the housing via the two arms.

11. The carrier of claim 1 , wherein an end of the spool is rollingly engaged to a housing, the spool sized to receive therein a bobbin of the yarn from an opposed free end of the spool, the spool having a tightening mechanism to secure the bobbin to the spool for concurrent rotation.

12. A carrier for supporting a yarn to be used by a braiding machine, comprising:
a spool carrying the yarn;
a motor drivingly engaged to the spool;
at least one sensor for producing data about a condition of the yarn in the spool; and
a controller operatively connected to the motor and to the at least one sensor, the controller having a processor and a computer-readable medium operatively connected to the processor and having instructions stored thereon executable by the processor for:
receiving said data from the at least one sensor, the receiving of the data including receiving data about a quantity of yarn remaining around the spool;
determining operation parameters of the motor based on the received data; and
operating the motor per the determined operation parameters to create the desired tension in the yarn.

13. The carrier of claim 12 , wherein the at least one sensor is a potentiometer engaged to an arm pivotably mounted to a housing of the carrier supporting the spool, a distal end of the arm biased in abutment against the yarn of the spool, the distal end of the arm movable toward the spool as the yarn is consumed, the receiving of the data about the quantity of the yarn includes receiving a signal from the potentiometer indicative of the quantity of the yarn remaining.

14. The carrier of claim 12 , wherein the determining of the operation parameters includes determining a torque generated by the motor.

15. The carrier of claim 14 , wherein the determining of the torque includes determining a current to be supplied to the motor to achieve the determined torque.

16. The carrier of claim 12 , wherein the receiving of the data includes receiving data about an angular position of the motor.

17. The carrier of claim 16 , comprising an encoder operatively coupled to the motor and to the controller, the receiving of the data includes receiving the angular position of the motor from the encoder.

18. The carrier of claim 12 , comprising a battery operatively connected to the controller and to the motor, the battery located within a housing of the carrier, the spool rollingly engaged to the housing.

19. The carrier of claim 12 , wherein the spool is disposed around the motor, a shaft of the motor supported by two arms protruding from a housing, the spool rollingly engaged to the housing via the two arms.

20. The carrier of claim 12 , wherein an end of the spool is rollingly engaged to a housing, the spool sized to receive therein a bobbin of the yarn from an opposed free end of the spool, the spool having a tightening mechanism to secure the bobbin to the spool for concurrent rotation.
