Abstract

A textile machine for producing cross-wound packages, which has a plurality of workstations on the two longitudinal sides of the machine and is equipped with a tube magazine arranged at an end of the machine, the tube magazine having a plurality of empty-tube transport rows, driven by electric motor and loaded with empty tubes of different yarn lots. In order to avoid the fixed division of the empty-tube transport rows that hitherto was defined by the construction of the tube magazine and thus to avoid limited variations in the yarn lot management, the invention provides for the empty-tube transport rows to be equipped with electric drives, which are connected to a control unit of the textile machine, the machine control system being designed in such a way that different lot management programs are set by software.

First claim

What is claimed is:

1. A textile machine for producing cross-wound packages, having a plurality of workstations on the two longitudinal sides of the machine and equipped with a tube magazine arranged at an end of the machine, the tube magazine having several empty-tube transport rows, driven by electric motor and loaded with empty tubes of different yarn lots,
characterized in that
the empty-tube transport rows are equipped with electric drives connected to a control unit of the textile machine, a common drive is used for maximum two empty-tube transport rows, the control unit being configured in such a way that different lot management programs are set by software, and each of the lot management programs of the control unit is set to a different number of yarn lots, without any changes having to be made to construction of the tube magazine.

2. The textile machine for producing cross-wound packages according to claim 1 , characterized in that the empty-tube transport rows of the tube magazine are assigned to a certain specifiable yarn lot by the lot management programs.

3. The textile machine for producing cross-wound packages according to claim 1 , characterized in that the electric drives of the empty-tube transport rows are controlled by the control unit in accordance with the set lot management programs.

4. The textile machine for producing cross-wound packages according to claim 1 , characterized in that the electric drives for the empty-tube transport rows are designed as stepper motors.
