Definitions
- the invention relates to a method for optimizing the number of workstations which can be supplied simultaneously with additional underpressure of a textile machine producing a multitude of workstations having cheeses according to the preamble of claim 1.
- suction air is constantly needed to operate a cop dust removal, that is to say a device which, during the rewinding process, ensures that the dirt and dust produced by the spinning cop when the thread runs out are disposed of.
- the thread end of the so-called lower thread is taken up by a gripper tube, which can also be acted upon by negative pressure, and likewise conveyed to the thread splicing device.
- the yarn ends of upper and lower thread are connected in the Fadens splicer by compressed air.
- the speed of the drive motor of the vacuum unit is increased to provide a predetermined increased negative pressure with which then the increased Saugluft band can be met. That is, the speed of the drive motor of the vacuum unit is adjusted so that the pressure level in the suction system is always maintained at a minimum value during the execution of the first additional intake-requiring event and other similar events occurring in the meantime.
- the speed of the drive motor of the vacuum unit is then back regulated to the speed to cover the basic vacuum demand.
- Such an increased additional vacuum requirement for example, always indicates a self-sufficient workstation when it has to be re-spun at the relevant workstation. That is, when the end of the thread sought by a workstation's own, under horrbeetzbergerbare suction nozzle on the surface of the cheese, taken up, transported to a Fadenanspinnvortechnik and prepared there for the piecing.
- the invention has for its object to provide a method which ensures that in case of need always the maximum possible number of jobs of the textile machine is supplied with the required additional negative pressure, said ensures that the negative pressure in the Saug Kunststoffstrom the textile machine does not fall below a basic requirement of the textile machine representing limit.
- the inventive method which operates on the so-called maximum principle, has the particular advantage that in case of need always the entire, currently available potential of the suction air system of the textile machine is utilized.
- the maximum number of these each still be supplied simultaneously with additional negative pressure work is variable and is determined from the, as determined above number, increased by the number of currently with additional negative pressure on the basis of the actual speed of the drive motor already supplied jobs. This maximum number of circuits exceeding negative pressure requirements are rejected.
- the maximum number of jobs that can still be supplied simultaneously with additional negative pressure depends, for example, on the length of the textile machine, the degree of soiling of the dirt chamber, the installation height of the textile machine and similar parameters, as can be seen from the actual speed of the drive motor.
- the number of jobs that can still be supplied simultaneously with additional negative pressure is calculated, inter alia, from the vacuum requirement of a single workstation or from the speed increase of the drive motor of the suction air unit required to cover this underpressure requirement.
- the amount of an additional vacuum requirement of a job also results from the respective yarn parameters.
- Coarser yarns and hairier yarns require a higher negative pressure to be able to suck a yarn end from a supply spool and prepare and splice the yarn end into thread-splicing preparation tubes as fine, smoother yarns.
- the method steps described above ensure that, on the one hand, the vacuum level in the suction air system does not fall below a predefinable limit value and, on the other hand, all work stations which are supplied with additional compressed air always receive sufficient suction air.
- the figure shows a diagram of the schematically indicated by a curve 1 speed curve of the drive motor Saug Kunststoffaggregates the textile machine and the schematically indicated by the curve 2 negative pressure curve in the Saug Kunststoffstrom the textile machine when restarting the textile machine after a batch change.
- the abscissa shows the time course of the method according to the invention, wherein the various times described in more detail below with A, B, C, etc. are marked.
- the drive motor of Saug Kunststoffaggregates runs at a speed di 3t , resulting from various parameters, such as the degree of contamination of the dirt chambers, the length of the textile machine, the height of the site of the textile machine, etc.
- control device of the textile machine ensures that the drive motor of Saug Kunststoffaggregates to its maximum speed dm ax . is accelerated.
- the value for the speed reserve d res . which is the difference between d ⁇ x . and d iat , as well as the respective additional vacuum consumption of a single workstation calculated or the speed increase, which is necessary to cover the additional vacuum requirements of a single job.
- the negative pressure p begins to fall in the Saugluftstrom and reached at time D, the negative pressure level p G , which is necessary to cover the basic needs of the textile machine.
