Definitions

  • the present invention relates to an open-end rotor spinning machine according to the preamble of claim 1.
  • the associated spinning device can be automatically re-spun by the functional elements.
  • Open-end rotor spinning machines have also long been known and widely used in the textile industry, whose work stations are supplied with service units, so-called piecing carriages, which can be moved along the workstations of these textile machines during the spinning operation.
  • piecing carriages Such as in the DE 44 43 818 B4 or in the DE 196 36 395 B4 Anspinnaggregate described engage automatically when there is a need for action at one of the jobs of open-end rotor spinning machines.
  • Such a need for action exists, for example, when there has been a spinning break at one of the workplaces, for example due to the completion of a cross-wound bobbin.
  • the responsible piecing unit runs to the affected workstation, transfers the finished cross-wound bobbin on a bobbin conveyor belt, places a new empty tube in the creel and performs a piecing process.
  • the piecing which perform the piecing process
  • a control device on which a lot of parameters that affect the piecer more or less strongly must be readjusted after a batch change.
  • the extra length R3 for the thread return, the voltage E2, the fill factor E2, the start deduction, the additional rotation and the draw-in addition Delta E3 should be mentioned as piecing parameters, which should be set newly defined , but also numerous other parameters, for example, the length of the addition, the length of the additional rotation, the amount of additional rotation, the fiber flight time etc ..
  • a piecing unit for an open-end rotor spinning machine which is equipped with a sensor element with which a running thread can be scanned for thick and thin areas.
  • the piecing unit has a control device with a user interface as well as a knowledge store in which function tables are stored for a piecing process.
  • the control device of the service unit is also connected via a data line to a machine center of the open-end rotor spinning machine, which has a data memory in which the machine data of the relevant textile machine are stored.
  • a piecing unit which is equipped with a special control device and an evaluation device.
  • the control device ensures that in a first test phase, first without doffer charging Delta E3, a Testanspinner is generated, which is then removed again.
  • the evaluation determines the length of each caused in the thread running direction caused by the Testanspinner thin spot and determined from the length of the thin spot required for the compensation of the thin area extent of collection draw delta E3, resulting in a significant improvement of the piecing.
  • the invention has the object to modify a piecing-free open-end rotor spinning machine so that in the case of a lot change a simple, fast and proper adjustment of the main piecing parameters is possible.
  • the optimized basic setting of piecing parameters calculated by the central control device can be transmitted to the workstation's own control devices via a bus system or the like.
  • control devices of the workstations ensure that after a spinning interruption at a work site, the functional elements of the affected workstation are controlled during the piecing process in such a way that the resulting piecer, in particular as regards its strength and its appearance, is formed almost yarn-like.
  • the workstation's own control devices can be designed so that they are able to calculate an optimized basic setting of the piecing parameters using a mathematical calculation method of a few piecing the concerned easy to understand specifications and some known spinning parameters ,
  • the easy-to-understand specifications relating to the piecer are fixed values which are processed in the computer device if required so that the computer device calculates the required optimized piecing parameters from these fixed values, for example at the press of a button.
  • the computer device can, if necessary, calculate the required, optimized piecing parameters.
  • the operator also inputs whether a coarse adjustment or fine adjustment is desired with respect to the thickness of the new piecer (claim 7).
  • the operation of the device according to the invention requires neither specially trained and / or experienced operating personnel, since neither spinning parameters have to be determined empirically, nor are any laboratory examinations and / or complex measuring equipment necessary for a batch change.
  • the inventive, in the central control unit of an open-end rotor spinning machine integrated control device can be the parameterization of the piecing significantly simplify in particular open-end rotor spinning machines, which are not equipped with piecing.
  • FIG. 1 schematically shows a front view of a piecing-free open-end rotor spinning machine 1 with a plurality between two end racks 2 and 3 arranged, largely self-sufficient jobs. 4
  • the end racks 2, 3 of this open-end rotor spinning machine 1 are, as is known and therefore not shown in detail, connected via continuous supply and disposal channels, for example one Vacuum channel for supplying the arranged in the field of jobs 4 spinning devices 5 with spinning vacuum, an electronic channel for a bus system 13 and a cable channel for supplying the work stations 4 with electrical energy.
