Definitions

  • the invention relates to a method for operating a textile machine and a textile machine with several similar work stations, each of which has a basic negative pressure requirement for regular production operations and an additional negative pressure requirement after an interruption in production at the work location, and with a suction air system with a limited suction power to provide the negative pressure at the workplaces.
  • Such a textile machine has a suction air system with at least one controllable suction air unit, the suction power of which can be regulated via the speed of a drive motor.
  • the vacuum requirement of an individual job can, however, especially if the jobs, such as in the DE 101 39 075 A1 described, as essentially self-sufficient workplaces are designed to increase significantly at times.
  • Workplaces of open-end rotor spinning machines always have such an increased additional vacuum requirement, for example, when new spinning has to be carried out at a workstation. This means when, after a spinning interruption, the thread end that has accumulated on the surface of a cheese has to be searched for, picked up by a workstation's own vacuum nozzle, transported to the associated open-end spinning device and prepared there for the piecing process.
  • open-end rotor spinning machines are usually equipped with a suction air system, in which the speed of the drive motor of the suction air unit can be increased to a maximum speed if necessary to increase the vacuum level
  • these known textile machines often result in considerable difficulties when the suction air requirement of the textile machine overall is above the maximum suction air supply of the suction air system concerned.
  • the suction air system of the textile machine although the drive motor of the suction air unit is already running at maximum speed, cannot provide enough negative pressure to simultaneously supply all workplaces that require additional negative pressure with the necessary suction air, without the spinning negative pressure required by the workplaces simultaneously falling a minimum level drops.
  • suction air is constantly required, for example to operate a bobbin dedusting system, i.e. a device that ensures that the dirt and dust produced when the thread runs off the bobbin is disposed of during the winding process.
  • a bobbin dedusting system i.e. a device that ensures that the dirt and dust produced when the thread runs off the bobbin is disposed of during the winding process.
  • the workplaces of such textile machines have what is known as a thread catching nozzle, which is also constantly supplied with suction air during the rewinding process.
  • textile machines of this type also have, for example, in the DE 44 46 379 A or in the DE 195 11 960 A1 described, via a machine's own suction air system with a suction air unit, the drive motor of which is connected to a frequency converter and its speed can be set in a defined manner. This means that the speed of the drive motor can be adjusted within certain limits according to the suction air requirement of the textile machine.
  • the drive motor of the suction air unit runs during the regular work process preferably at a speed at which the negative pressure in the suction air system does not fall below a certain minimum level, i.e. at which the so-called basic suction air requirement of the textile machine is met.
  • the speed of the drive motor of the suction air unit is increased in order to provide a predeterminable increased vacuum, and in this way the increased demand for suction air is realized.
  • the speed of the drive motor of the suction air unit is adjusted so that the pressure level in the suction air system is always kept at a minimum value when processing the first event that requires additional suction air and other similar events that have occurred in the meantime. After the last of these events has been processed, the speed of the drive motor of the suction air unit is then regulated back to the speed to cover the basic vacuum requirement.
  • the invention is based on the object of developing a method which enables the numerous workstations of a textile machine producing cross-wound bobbins to be restarted as quickly as possible, even when difficult conditions exist.
  • a method for operating a textile machine with several similar work stations each of which has a basic negative pressure requirement for regular production operations and an additional negative pressure requirement after a production interruption at the work location, and with a suction air system with a limited suction power to provide the negative pressure proposed to the workplaces.
  • a minimum negative pressure is specified here.
  • the number of workplaces simultaneously supplied with additional negative pressure is limited so that the minimum negative pressure is not undershot.
  • a sub-negative pressure is specified which is below the minimum negative pressure and, in the event of a specified event, the number of workplaces simultaneously supplied with additional negative pressure is limited so that the sub-negative pressure is not undershot.
  • the method according to the invention has the particular advantage that in this way the suction air potential made available by the suction air system of the textile machine can be used to a greater extent for the additional supply of jobs.
  • the drive motor of the suction air unit of the suction air system preferably runs simultaneously at maximum speed and generates a maximum compressed air potential in the suction air system of the textile machine.
  • a relatively large vacuum reserve is then available, which can advantageously be used to supply a large number of workplaces with additional compressed air and thus to resume production of a large number of other workplaces. In the case of an open-end rotor spinning machine, production is resumed by re-spinning the workplaces.
  • the invention creates a maximum of quality with an optimized production speed. It is ensured that the minimum negative pressure required for quality in regular production operations is maintained.
  • the negative pressure is only lowered to the sub-negative pressure in the event of certain predetermined events in order to be able to resume regular production as quickly as possible.
  • the quality losses that may occur as a result of the lower negative pressure are hardly significant overall, since the sub-negative pressure is only set for a short time.
  • the event is the start-up of the textile machine after a machine standstill, during which all workplaces have an additional vacuum requirement in order to resume production. If the sub-vacuum is set after a machine standstill, the workstations of the textile machine can resume their regular production operations as quickly as possible. Such machine downtimes can be caused, for example, by malfunctions in the power supply equipment or by lot changes.
  • the event is the start-up of a group of workstations which at the same time have an additional vacuum requirement.
  • Such a definition of the event is particularly useful in multi-batch operation of the textile machine.
  • a multi-lot operation there can be several groups of workplaces on which different lots are produced.
  • a group of workplaces is then formed from several workplaces on which the same batch is produced.
  • this group of workplaces then simultaneously has an additional vacuum requirement.
  • the number of workplaces that can be simultaneously supplied with additional negative pressure is increased from a somewhat low number to a significantly larger number.
  • the number of jobs that can be supplied with additional negative pressure at the same time can for example be increased from about ten jobs to about twenty jobs, as has been customary up to now, which almost halves the start-up time of the textile machine that has hitherto been customary.
  • the number of workplaces that can be supplied with additional negative pressure at the same time is not only dependent on the sub-negative pressure set, but also on other, in some cases quite different, factors.
  • the maximum number of workplaces that can be supplied with additional negative pressure at the same time also depends, for example, on the material and the material thickness of the bobbins to be produced on the workplaces, the degree of soiling of the dirt chambers of the suction air system, the installation height of the textile machine and similar parameters.
  • Coarser and hairier yarns require a higher negative pressure than fine, smoother yarns in order to suck off a yarn end from a pay-off bobbin and to be able to prepare and splice the yarn end in preparation tubes for a yarn splice.
  • the temporary lowering of the level of the negative pressure prevailing in the suction air system to a sub-negative pressure can be set by the operating personnel in a defined manner. This means that by lowering the level of the negative pressure in the suction air system to a temporary sub-negative pressure, which can be initiated by the operating personnel, if necessary, especially after a machine standstill, it is possible to react immediately in such a way that the subsequent production start of the workstations of the textile machine as much as possible demanded a short period of time.
  • a textile machine with several similar work stations each of which has a basic negative pressure requirement for regular production operations and an additional negative pressure requirement after an interruption in production at the work station, and with a suction air system with a limited suction power to provide the negative pressure at the work stations is also proposed .
  • the control device can also be given a sub-negative pressure which is below the minimum negative pressure.
  • the control device is designed to temporarily limit the number of workplaces simultaneously supplied with additional negative pressure in the event of a predetermined event so that the sub-negative pressure is not undershot.
  • the operator can therefore enter two negative pressures on the control device. These are, on the one hand, the minimum negative pressure, which is used by the control device in regular production operation as the lower limit, and, on the other hand, the sub-negative pressure to which the negative pressure is lowered by the control device during the specified event.
  • the textile machine according to the invention with its control device is designed to carry out the method according to the invention and its preferred embodiments.
  • the start-up of the textile machine after a machine standstill, in which all workplaces have an additional vacuum requirement is stored as an event in the control device.
  • the start-up of a group of workstations that simultaneously have an additional vacuum requirement can also be stored as an event in the control device.
  • the temporary lowering of the spinning vacuum preferably increases the number of work stations that can be simultaneously supplied with additional vacuum from a first number to a second number.
  • the method according to the invention is preferably used in connection with an open-end rotor spinning machine and the textile machine according to the invention is preferably designed as an open-end rotor spinning machine.
  • the production company is thus a spinning company. After the production interruption, that is to say in this case a spinning interruption, the additional negative pressure is required for the re-spinning of the job.
  • the negative pressure is the spinning negative pressure.
  • the Figure 1 shows, based on a diagram through a curve 1, the negative pressure profile p in the suction air system of a textile machine.
  • Curve 1 shows the negative pressure profile p both during regular spinning operation and after restarting the textile machine after a lot change or an involuntary machine standstill. Curve 1 specifically shows the predeterminable level of the spinning vacuum that is present in the rotor housings of the open-end spinning devices in the area of the work stations of a rotor spinning machine.
  • Curve 2 shows schematically the speed profile of the drive motor of the suction air unit of the textile machine, i.e. the speed profile of the drive motor both during regular spinning operation and after restarting the textile machine after a lot change or an involuntary machine standstill.
  • Z 1 shows the number of jobs that can additionally be supplied with negative pressure when the jobs work with a minimum spinning negative pressure p min .
  • Z 2 reveals the number of jobs that can additionally be supplied with negative pressure when the jobs are operated with a sub-spinning negative pressure p sub .
  • the abscissa shows the course of the method according to the invention over time, the various points in time described in more detail below being identified by A, B, C, etc.
  • the level of the spinning vacuum prevailing in the rotor housings is indicated by p and the speed level of the drive motor of the suction air unit of the textile machine is indicated by d.
  • the drive motor of the suction air unit of the open-end rotor spinning machine runs during the regular spinning operation of the textile machine at a speed d max compared to its maximum speed. lower speed d is .
  • a predeterminable minimum spinning vacuum p min prevails during this time. Since all workplaces are initially running properly, the number of workplaces to be supplied with additional negative pressure at the same time is 0.
  • control device of the textile machine ensures that the drive motor of the suction air unit is set to its maximum speed d max . is accelerated. This maximum speed d max . is reached at time B, for example.
  • the level of the spinning negative pressure in the suction air system would be if at time B there was no additional negative pressure requirement due to the aforementioned workplaces to be re-spun, as indicated by the dashed line 1 ', to a maximum spinning vacuum p max . increase, which is well above the minimum spinning vacuum p min . would be.
  • the control of the textile machine has at the same time derived from the difference between the maximum spinning vacuum p max . and the minimum spinning vacuum p min . as well as the additional negative pressure consumption of an individual job, the number Z 1 of jobs is calculated that from time B is simultaneously supplied with additional negative pressure, that is, can be spun again at the same time without the spinning negative pressure in the suction air system falling below the minimum spinning negative pressure p min . drops, that is, despite the supply of a number Z 1 of work stations with additional negative pressure, the spinning negative pressure in the suction air system remains at a minimum spinning negative pressure p min .
  • the maximum speed d max of the drive motor of the suction air unit is again reduced to speed d ist , which happened at time D.
  • the level of the spinning negative pressure in the suction air system remains at a minimum spinning negative pressure Pmin.
  • the point in time at which a major malfunction occurs is shown with E. That is, at time E, the rotor spinning machine switches off, for example due to a fault in the power supply devices, and comes to a standstill, which happened at time F. At time F, the speed of the drive motor is do and the spinning vacuum in the suction air system is correspondingly p 0 .
  • the operating personnel sets a sub-spinning vacuum p sub on the control of the textile machine. That means when starting up the open-end rotor spinning machine there is temporarily a sub-spinning negative pressure p sub in the area of the suction air system of the textile machine , which is below the minimum spinning negative pressure p min which is usual during regular spinning operation of the rotor spinning machine. lies.
  • the rotor spinning machine is restarted at time G. Since at time G there are a large number of additional suction air requests from workplaces that all want to spin again immediately after the incident, the control device of the textile machine immediately ensures that the drive motor of the suction air unit is set to its maximum speed d max . accelerated, which is reached at time H. This means that if there were no additional negative pressure requirement from jobs that want to piecing, a maximum spinning negative pressure p max would now be in the suction air system of the textile machine, as indicated by the dashed curve 1 '. to rule. However, in the control device of the textile machine, the difference between the set sub-spinning negative pressure p sub and the maximum spinning negative pressure p max .
  • the number Z 2 of work stations is calculated that can be simultaneously supplied with additional suction air while the textile machine is running without the risk of the negative pressure in the suction air system of the textile machine falling below the specified sub-spinning negative pressure p sub decreases.
  • the control of the textile machine corrects the negative spinning pressure set in the suction air system of the textile machine.
