Abstract

A sleeve magazine for a textile machine and operational method include multiple transport elements each with a plurality of holders configured for holding a sleeve, wherein each transport element is driven to move the holders and sleeves to a removal point. A removal device at the removal point removes the sleeves from the holders. A controller controls movement of the individual transport elements such that the holder of at least one transport element is moved with the sleeve thereon to the removal point. The controller actuates the removal device to remove the sleeve from the holder at the removal point while the holders of the remaining transport elements are maintained outside of the removal point so as not to interfere with removal of the sleeve from the holder at the removal point.

First claim

The invention claimed is:

1. A method for removing individual sleeves from a sleeve magazine of a textile machine, wherein the sleeve magazine further includes multiple transport elements each with a plurality of holders configured for holding a sleeve, wherein the transport elements are driven to move the holders and sleeves to an individual respective removal point associated with each of the transport elements, and wherein a removal device is arranged so as to extend across all of the removal points to remove the sleeves from the holders that are located at the individual respective removal point for each of the transport elements, the method comprising:
with a controller, controlling movement of the individual transport elements such that the holder of at least a first transport element is moved with the sleeve thereon to the individual respective removal point associated with the first transport element; and
with the controller, actuating the removal device and removing the sleeve from the holder at the individual respective removal point associated with the first transport element while holders of the remaining transport elements are maintained outside of the individual respective removal point associated with each of the remaining transport elements so as not to interfere with removal of the sleeve from the holder at the individual respective removal point of the first transport element.

2. The method of claim 1 , wherein the removal device is controlled to remove a plurality of the sleeves at the individual respective removal point from the holders of a plurality of the transport elements.

3. The method of claim 1 . wherein the transport elements are individually activated to move the one of the holders thereon to the individual respective removal point of the transport element while remaining ones of the transport elements are stationary.

4. The method of claim 1 , wherein the removal device is actuated upon detecting a position of the sleeve at the individual respective removal point of the first transport element with a sensor.

5. The method of claim 1 , wherein the removal device is configured and controlled to push the sleeve from the holder at the individual respective removal point of the first transport element.

6. A sleeve magazine for a textile machine, comprising:
a plurality of adjacently disposed transport elements, wherein each transport element comprises a plurality of holders arranged thereon for receipt of respective sleeves;
a motor configured to drive the transport elements in a path such that the holders are moved to a removal point for removal of the sleeves therefrom, wherein each transport element has an individual respective removal point associated therewith;
a removal device operably arranged at the removal point so as to extend across all of the removal points:
a controller in communication with the transport elements and the removal device, the controller configured to:
control the individual transport elements such that the holder with the sleeve thereon of at least a first transport element is moved to the removal point associated with the first transport element; and

actuate the removal device to remove the sleeve from the holder at the removal point associated with the first transport element while maintaining the holders of the other transport elements outside of the respective removal point of the other transport elements.

7. The sleeve magazine of claim 6 , wherein the removal device is configured to remove a plurality of the sleeves from the holders of a plurality of the transport elements at the individual respective removal point of the plurality of transport elements.

8. The sleeve magazine of claim 6 , wherein the individual respective removal point for the transport elements are also adjacent to each other.

9. The sleeve magazine of claim 6 , wherein the removal device comprises a pusher element that engages and pushes the sleeve from the holder at the individual respective removal point associated with the first transport element.

10. The sleeve magazine of claim 6 , wherein the removal device is pneumatically or electrically driven.

11. The sleeve magazine of claim 6 , further comprising a sensor in communication with the controller and disposed to detect a position of the sleeve at the removal point associated with first transport element.

12. The sleeve magazine of claim 6 , further comprising a separate motor or a separate clutch configured to each transport element.

13. The sleeve magazine of claim 6 , wherein the holders comprise pins or supports on which the sleeves are placed.

14. The sleeve magazine of claim 6 , wherein the transport elements comprise a flexible member driven in a revolving path and arranged transversely or longitudinally with respect to a longitudinal axis of the textile machine.

15. The sleeve magazine of claim 14 , wherein the revolving path is an oval path or a multiple-deflection meandering path.

16. The sleeve magazine of claim 6 , wherein the transport elements are modular, each module arranged adjacent to one another transversely or longitudinally with respect to a longitudinal axis of the textile machine.
