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.

Textile machine producing cross-wound packages

A textile machine producing cross-wound packages with a plurality of identical workstations which are arranged in the area of the longitudinal sides of the textile machine and each of which has a winding device, and equipped with a tube supply device which includes a central tube magazine and at least one tube conveyor belt installed in the area of the longitudinal sides of the machine, in which case a cross-wound package can be removed, if necessary, from the winding device of the relevant workstation on the textile machine producing cross-wound packages and can be transferred to a cross-wound package transport device running the length of the machine, and an empty tube provided on the tube conveyor belt of the tube supply device can be inserted by means of a tube gripper into the winding device of the relevant workstation. The tube supply device is designed in such a way that the tube conveyor belt can be used as a tube accumulator for empty tubes during the operation of the textile machine producing cross-wound packages. In order to improve the efficiency of such a textile machine producing cross-wound packages, in particular to minimize significantly the tube delivery times arising in the event of yarn lot changes at a textile machine producing cross-wound packages, a drive is connected to the at least one tube conveyor belt, which drive enables reversible operation of the tube conveyor belt.

Textile machine producing cross-wound packages and method for operating a textile machine producing cross-wound packages

A textile machine for producing cross-wound packages, comprising a plurality of workstations, each of which has at least one pneumatic consumer, and comprising a suction system which has at least one vacuum source to which the pneumatic consumers of the workstations are connected via a machine-length vacuum duct arranged in the region of the central axis between two rows of workstations. In order to modify such a textile machine producing cross-wound packages in such a way that it is ensured that the required minimum spinning vacuum is always available at all workstations of the textile machine during spinning operation, according to the invention the textile machine producing cross-wound packages has, in addition to the vacuum duct, a machine-length bypass duct which is also installed in the region of the central axis and is arranged above chain ducts for service units.

Method for operating a service unit for processing work orders regarding a cross-wound package/empty tube doffing process employed at spinning machines producing take-up packages that process at least two different lots, whereby the service unit is fed an empty tube via the spinning machine's tube feed track, and the fed empty tube is taken up by the service unit. If the current work order for the cross-wound package/empty tube doffing of the workstations expires before it is processed and the empty tube is exchanged and another work order has come in which is for a workstation requiring a cross-wound package/empty tube doffing for another lot, the already taken up empty tube is released by the service unit, and the service unit takes up an empty tube of another lot in order to be able to carry out a cross-wound package/empty tube doffing process at the other workstation.
