Abstract

A spinning machine and method are provided for feeding a sliver end of a sliver deposited in a can to a spinning position of the spinning machine, wherein the spinning machine includes a plurality of adjacently arranged spinning positions and a plurality of cans arranged in at least a first row under the spinning positions. With a sliver gripper of a robot, the method includes seeking the sliver end from one of the cans in an area that includes at least one adjacent spinning position to a spinning position to be supplied. The sliver end is grasped with the sliver gripper and fed to the spinning position to be supplied.

First claim

The invention claimed is:

1. A method for feeding a sliver end of a sliver deposited in a can to a spinning position of a spinning machine, wherein the spinning machine comprises a plurality of adjacently arranged spinning positions and a plurality of cans arranged in at least a first row under the spinning positions, the method comprising:
positioning a robot at an adjacent spinning position to the spinning position to be supplied such that a sliver gripper of the robot is at the adjacent spinning position;
with the sliver gripper of the robot at the adjacent spinning position, seeking the sliver end from one of the cans;
grasping the sliver end with the sliver gripper; and
feeding the sliver end to the spinning position to be supplied.

2. The method as in claim 1 , comprising moving the robot along the spinning machine and positioning the robot at the spinning position to be supplied or at the adjacent spinning position.

3. The method as in claim 1 , comprising moving the sliver gripper relative to the robot along the spinning machine to the area that includes the adjacent spinning position or to an area that includes a can in a second row of the cans adjacent to the first row of cans.

4. The method as in claim 3 , wherein the shiver gripper is configured to grasp the sliver end from multiple possible positions at the adjacent spinning position.

5. The method as in claim 1 , wherein the sliver gripper seeks the sliver end on a top side of the can or at a circumference of the can.

6. A method for feeding a sliver end of a sliver deposited in a can to a spinning position of a spinning machine, wherein the spinning machine comprises a plurality of adjacently arranged spinning positions and a plurality of cans arranged in at least a first row under the spinning positions, the method comprising:
with a sliver gripper of a robot, seeking the sliver end from one of the cans in an area that includes at least one adjacent spinning position to a spinning position to be supplied;
grasping the shiver end with the sliver gripper;
feeding the sliver end to the spinning position to be supplied; and
wherein the robot is at the adjacent spinning position when the sliver end is grasped, and further comprising moving the robot with the grasped end to the spinning position to be supplied before feeding the sliver end to the spinning position to be supplied.

7. A spinning machine configured to perform the method according to claim 1 .

8. The spinning machine as in claim 7 , wherein the robot is movable along the spinning machine.

9. The spinning machine as in claim 8 , wherein the robot is also movable along additional spinning machines.

10. The spinning machine as in claim 7 , wherein the sliver gripper is movable relative to the robot along the spinning machine to the area that includes the adjacent spinning position or to an area that includes a can in a second row of the cans adjacent to the first row of cans.

11. The spinning machine as in claim 10 , wherein the sliver gripper is configured to grasp the sliver end from multiple possible positions at the adjacent spinning position.

12. The spinning machine as in claim 7 , wherein the sliver gripper comprises a width so as to grasp the sliver end at at least two adjacent spinning positions relative to the spinning position to be supplied.

13. The spinning machine as in claim 7 , wherein the sliver gripper comprises a suction unit for drawing in the sliver end.

14. The spinning machine as in claim 7 , wherein the sliver gripper comprises a blowing unit for feeding the sliver end into the spinning position to be supplied.
