Definitions

  • the present invention relates to a method for operating a textile machine with a large number of similar work stations arranged next to one another, each of which has different, energy-consuming work elements.
  • a control unit of the textile machine allocates the total energy resources available for the large number of jobs to individual jobs requiring energy resources.
  • the invention relates to a corresponding textile machine.
  • Generic textile machines are designed either as spinning machines for producing a yarn or as winding machines, which wind around a yarn that has already been produced.
  • the workplaces of the textile machines have numerous working elements for the production or handling of the yarn, such as spinning devices, take-off devices and winding devices.
  • the workplaces have working bodies to resume regular operations in the event of an interruption, i.e. to carry out service operations such as piecing processes (piecing or splicing) and bobbin changes.
  • suction nozzles for finding a thread end, blowing nozzles for cleaning purposes or working elements for thread handling should be mentioned.
  • the working organs require certain amounts of energy resources, ie electricity, compressed air or vacuum.
  • energy resources ie electricity, compressed air or vacuum.
  • the total energy resources available on the textile machine are limited, only a certain number of work stations can be supplied with energy resources at the same time. It has therefore prevailed in the prior art that jobs that require energy resources request them.
  • a control unit allocates the requested energy resources to the work stations as long as the total available energy resources are not exceeded. However, requests that exceed the available energy resources are deferred.
  • the working organs require different amounts of energy resources at different times. For example, some working organs require energy resources only during regular operation, but not during service operations. Other working organs require energy resources only during a service operation, but not during regular operation. Other working elements require larger amounts of energy resources when starting up after an interruption in operation, while only small amounts are required in regular operation.
  • suction air requirements contain information about the planned course of their suction air requirements, which is taken into account accordingly when allocating the suction air requirements.
  • the DE 10 2016 106 107 A1 also proposes dividing service operations into sub-sequences and requesting and allocating resources not for the entire service operation but only for the respective sub-sequence. A pending sub-sequence is then carried out independently of the other sub-sequences of the respective service operation when the energy resources required for the execution of this sub-sequence are available. Partial sequences can thus already be processed when not enough energy resources are available for the entire service operation.
  • the object of the present invention is to further improve the allocation of energy resources to the work stations.
  • the energy resources available for the large number of work stations are allocated by a control unit of the textile machine to individual work stations requiring energy resources.
  • a partial number of at least two jobs from the large number of jobs is defined.
  • at least one of the different working elements is selected and the at least one selected working element is put into operation at the partial number of working positions.
  • a total consumption of the relevant energy resource is measured.
  • a total consumption of the relevant energy resource is determined when the at least one selected working element is at a standstill. From the difference between the determined total consumption and the partial number of jobs, a real individual consumption of the at least one selected working element per job is finally determined and taken into account in future by the control unit when allocating the energy resources.
  • a corresponding textile machine with a large number of similar jobs arranged next to one another, each of which has different energy-consuming working elements, contains a control unit which allocates the total energy resources available for the jobs to individual jobs requiring energy resources.
  • the control unit is designed to carry out the method.
  • the invention has recognized that the actual energy resource requirement or individual consumption of a working organ or a group of working organs can sometimes deviate significantly from a theoretically calculated or earlier empirically determined resource requirement. Reasons for this can be, among other things, soiling or wear and tear of certain components or working organs, a different design of individual jobs or working organs as well as different equipment of jobs, for example with certain spinning elements. Since the energy resources are now allocated on the basis of the determined, real individual consumption, it is possible that more energy resources can be allocated even if there are small deviations in the determined real consumption from the previously used, general requirements for energy resources, since the energy resources that are still available can be calculated precisely in this way.
  • the determination of the real individual consumption can take place both before and after the commissioning of the selected working unit at the partial number of jobs. Furthermore, the determination can also be made not only for a single working body, but also for a group of working bodies. For example, for a suction nozzle that carries out the thread search before a piecing or piecing process, it makes sense to determine the real individual consumption per suction nozzle. If, on the other hand, when starting up a workplace, for example, several drives at the workplace have to be put into operation at the same time or with only a small time lag, it can make sense here to jointly determine the real individual consumption for these several drives that are functionally related.
  • the invention is based on the assumption that, overall, similar conditions arise at similar jobs. It is therefore considered sufficient to determine the total consumption of the selected working organ (or the selected group of working organs) at several workplaces with just one measurement for the several workplaces and from this to calculate the individual consumption of the selected working organ per workplace. A time-consuming individual measurement per job is therefore not necessary. It goes without saying, however, that the individual consumptions can only be measured at work stations of the same type and equipped in the same way and, of course, can only be transferred to work stations of the same type and equipped in the same way. This must be taken into account when the textile machine is used in multiple batches.
  • the type of energy supply and the type of energy resource energy can be supplied and the energy resources allocated in different ways.
  • the supply of vacuum on a double-sided textile machine is often carried out separately for each side of the machine.
  • the variety of jobs, which on which the allocation of resources is based is formed in this case by all work stations on one long side of the textile machine.
  • the work stations of a section are supplied with electricity by a power pack.
  • the large number of jobs is formed by all the jobs in a section.
  • Other energy resources are made available centrally for the entire textile machine, so that the large number of jobs is formed by all jobs on the textile machine.
  • the energy resources are allocated accordingly, for example by a machine controller or also a section controller.
  • the real individual consumption is determined during the start of the textile machine before the start of production. In this way structural conditions of the textile machine or also current states of wear can be taken into account.
  • the actual individual consumption is determined lot-related before and/or during the start of a new yarn lot.
  • structural conditions and current states of wear can also be taken into account, as described above.
  • spinning means used for this special yarn lot and lot-specific settings at the work stations can also be taken into account.
  • the determination of such a lot-related individual consumption can also take place during operation of the textile machine at the beginning of a new yarn lot in the case of multi-lot occupancy. Only a partial number of work stations belonging to the same yarn lot is then defined, by means of which the individual consumptions are determined. The workplaces of the textile machine, which are processing other yarn lots can meanwhile continue to work in regular operation.
  • the real individual consumptions of several different working units or also several different groups of working units are determined one after the other.
  • the real individual consumptions are determined for each of the various working elements and are taken into account by the control unit when allocating the energy resources. It is through this possible to determine the real individual consumption for many partial sequences, if necessary even for all partial sequences of a service operation.
  • the available energy resources can be used particularly well in this way.
  • the control unit is also assigned a storage unit in which actual individual consumption of energy resources by the working elements is stored. Based on the energy resources already allocated and the total energy resources available, the control unit can now precisely calculate whether the currently requested energy resources can still be allocated or not.
  • the individual consumptions can be stored in a central storage unit or in a storage unit at the workplace.
  • shut-off valves for the spinning vacuum are opened simultaneously at the partial number of jobs and a first, self-adjusting vacuum level in a vacuum channel Textile machine is measured and if the shut-off valves continue to be closed at the partial number of jobs and a second, self-adjusting vacuum level is measured in the vacuum channel.
  • the real individual consumption of negative spinning pressure of an individual spinning device is determined from the difference between the two measured values.
  • the vacuum level that occurs is first measured with the shut-off valve closed and only then are the shut-off valves opened at the partial number of work stations and that the vacuum level that occurs is measured again.
  • a pneumatic blower unit is put into operation at the partial number of work stations at the same time and a first compressed air consumption that occurs is measured, that the blower units are stopped at the partial number of work stations and a second compressed air consumption that occurs is measured and that the real individual consumption of compressed air of an individual blower unit is determined from the difference between the two measured values.
  • a rotor drive is put into operation at the partial number of work stations, preferably at two work stations, and a first power consumption is measured, that the rotor drives are stopped at the partial number of work stations and a second power consumption is measured when the rotor drives are at a standstill at the partial number of work stations, and that the real individual consumption of current of a single rotor drive is determined from the difference between the two measured values.
  • the reverse measurement sequence is of course also conceivable for the two last-mentioned examples. It is only essential for the measurements that a stable condition has been established with regard to the negative pressure or the variable to be measured and that it is further ensured that only the total consumption of the energy consumers at the selected partial number of jobs is determined, i.e. it is not by chance that a similar energy consumer is active at another job.
  • the power consumption can be measured when the rotor drives are started up. From the real individual power consumption of a single rotor drive, it can then be calculated exactly how many spinning positions or how many rotor drives can start up at the same time.
  • the real individual consumption of electricity by an individual rotor drive can also be determined during the regular operating state. In this way, the consumption of jobs already in operation can also be taken into account when further allocating resources.
  • the power consumption when the rotor drives are started up is measured and compared to the power consumption when the rotor drives are stationary at the partial number of work stations, it is also possible to compare the power consumption when the rotor drives are started up with the power consumption of the rotor drives in the to compare regular operating conditions.
  • the real individual consumption of a single rotor drive during start-up can also be determined from this differential measurement.
  • the actual individual consumption values are determined again during ongoing production operations and are preferably updated in the storage unit. As already described, this can be done, for example, if only a new game is to be started. However, it is also conceivable to repeat the measurement during operation for a different operating state, in the case of vacuum consumption, for example with an uncleaned filter. Since consumers may also have to be deactivated for this purpose, this is preferably done when few events are taking place on the machine and therefore the efficiency of the machine is little influenced by the measurements.
  • Such repeated measurements can also reveal bottlenecks in the energy supply, for example if sufficient negative pressure can no longer be provided when the filter is occupied. If such repeated measurements of the total consumption are stored and compared with one another, resource limitations that occur during production operations can also be uncovered and eliminated. For example, early filter cleaning or another Machine settings eliminate a limitation of the vacuum resources that has occurred and thereby enable the allocation of the theoretically maximum possible number of resource requests.

  • FIG. 3a requires a suction nozzle 31 for the thread search significant amounts or resource shares of vacuum resources FSU.
  • the need for vacuum resources FSU for the thread search is over a third of the maximum capacity 32.
  • This requirement was defined once in the prior art and is linked to each request for vacuum resources FSU at a job 2 for the thread search.

  • the real individual consumption of a suction nozzle 31 is somewhat lower than the third of the maximum capacity 32 assumed above.
