Abstract
The invention relates to a method for the control of the travel movement of at least one service unit at a rotor-spinning machine, whereby the service unit services and/or controls an operating zone assigned to it containing a plurality of processing stations of the textile machine. The service unit is moved in the direction of its assigned operating zone when the detected position is located outside the assigned operating zone. In addition, the size of the operating zones is determined as a function of the workload of the service units and/or of the work efficiency of the service units.

A process for controlling travel movement of a service unit at a rotor spinning machine, comprising:
- assigning an operating zone to the service unit, the operating zone having a plurality of processing stations serviced by the service unit;
- monitoring and detecting the position of the service unit relative to the spinning machine;
- and
- moving the service unit back to its assigned operating zone upon detection that the service unit is beyond its respective assigned operating zone by automatically reversing the travel movement of the service unit, if the service unit is moving in a direction away from its assigned operating zone.
A process for controlling travel movement of a service unit at a rotor spinning machine, comprising:
- assigning an operating zone to the service unit, the operating zone having a plurality of processing stations serviced by the service unit;
- monitoring and detecting the position of the service unit relative to the spinning machine;
- moving the service unit back to its assigned operating zone upon detection that the service unit is beyond its respective assigned operating zone;
- and
- servicing processing stations with the service unit that are disposed along a path of travel of the service unit back to its assigned operating zone.
A process for controlling the travel movement of at least two service units at a rotor spinning machine, comprising:
- assigning a separate operating zone to each of the service units, the operating zone having a plurality of processing stations serviced by the respective service unit;
- and
- defining the size of the respective operating zones for each of the service units as a function of workload or work efficiency of the service units.
A process for controlling the travel movement of at least two service units at a rotor spinning machine, comprising:
- assigning an operating zone to each of the service units, the operating zone having a plurality of processing stations serviced by the respective service unit;
- defining the size of the respective operating zones as a function of workload or work efficiency of the servicing units;
- and
- wherein the size Na of the operating zone for the first service unit and the size Nb of the operating zone for the second service unit are empirically calculated as follows:
- Na=N/2 (100%−a+b)
- Nb=N/2 (100%+a−b)
- a=workload of the first servicing unit
- b=workload of the second servicing unit
- N=total number of processing stations to be serviced by the two service units.
A process for controlling the travel movement of at least two service units at a rotor spinning machine, comprising:
- assigning an operating zone to each of the service units, the operating zone having a plurality of processing stations serviced by the respective service unit;
- defining the size of the respective operating zones as a function of workload or work efficiency of the servicing units;
- and
- adding to an operating zone for a first service unit a portion of an operating zone of a second servicing unit that cannot be serviced by the second servicing unit.
A textile machine having a plurality of spinning processing stations and at least one traveling service unit for servicing said processing stations, and further comprising:
- a detection system operatively configured between said service unit and said processing stations that detects a position of said service unit as it travels alongside of said processing stations;
- a control system configured with said service unit, said control system automatically controlling movement of said service unit by a process wherein:
- an operating zone is assigned to the service unit, said operating zone having a plurality of said processing stations serviced by said service unit;
- position of said service unit relative to said processing stations is monitored and detected;
- and
- said service unit is moved to its assigned operating zone upon detection that said service unit is beyond its respective assigned operating zone by automatically reversing the travel movement of said service unit, if said service is moving in a direction away from its assigned operating zone.
A textile machine having a plurality of spinning processing stations and at least two traveling service units for servicing said processing stations, and further comprising:
- a control system configured with said service units, said control system automatically controlling movement of said service units by a process wherein:
- a separate operating zone is assigned to each of said service units, said operating zone having a plurality of said processing stations serviced by said respective service unit;
- and
- the size of said respective operating zones for each of said service units is defined as a function of workload or work efficiency of said service units.
