Abstract

A method is performed at a spinning machine that includes a plurality of spinning stations at which different yarn lots are spun. The method transports tubes from multiple tube magazines to the spinning stations. At the spinning station, a yarn is spun from a sliver deposited in a can and is wound onto the tube. An identical marking associated with a respective one of the different yarn lots is provided on the following components: each of the tubes, each of the tube magazines, a display device at the spinning station, a monitor at a machine control system, the cans at the spinning station, and a service unit that travels alongside of the spinning stations.

First claim

The invention claimed is:

1. A method performed at a spinning machine that includes a plurality of spinning stations at which different yarn lots are spun, comprising:
transporting tubes by means of a transport device from multiple tube magazines to the spinning stations;
at each spinning station, spinning a yarn from a sliver deposited in a can, and winding the yarn onto the tube at the respective spinning station; and
providing an identical marking associated with a respective one of the different yarn lots on the following components: each of the tubes, each of the tube magazines, a display device at the spinning station, a monitor at a machine control system, the cans at the spinning stations, and a service unit that travels alongside of the spinning stations.

2. The method of claim 1 , comprising changing the marking on the components when changing the yarn lot produced at the spinning stations.

3. The method of claim 1 , wherein the marking for each of the yarn lots is specified at the machine control system.

4. The method of claim 1 , wherein the marking is selected directly at the tube magazines, at the service unit, or at the spinning stations.

5. The method of claim 1 , wherein assignment of the spinning stations to a particular yarn lot is carried out at the machine control system or directly at each spinning station.

6. The method of claim 1 , wherein assignment of the tube magazines to a particular yarn lot is carried out at the machine control system or directly at each tube magazine.

7. The method of claim 1 , wherein assignment of a number of the tube magazines to a particular yarn lot is carried out by the machine control system.

8. A spinning machine, comprising:
a plurality of spinning stations at which different yarn lots are spun;
multiple tube magazines in which tubes are stored;
a transport device that transports the tubes from the tube magazines to the spinning stations;
a can at each spinning station having a sliver deposited therein, wherein a yarn is spun at the spinning station from the sliver and wound onto the tube at the respective spinning station;
a service unit that travels alongside of the spinning stations;
a machine control system;
an identical marking associated with each of the different yarn lots provided on the following: each of the tubes, each of the tube magazines, a display device at each spinning station, a monitor at the machine control system, the cans at the spinning stations, and the service unit.

9. The spinning machine of claim 8 , wherein the marking comprises a color, an icon, a pattern, a numeral, or text.

10. The spinning machine of claim 8 , wherein the marking is generated by a display, a bulb, a multi-position switch, a pushbutton, a colored band, or a label.

11. The spinning machine of claim 8 , further comprising sensors configured to check agreement between the markings at the spinning machine.
