Definitions

  • the invention relates to a method and / or a device for operating a cross-wound textile machine, which has a plurality of individually driven, autonomously operating workstations and a central control unit.
  • the cross-wound textile machine is, for example, a cross-winding machine or an open-end rotor spinning machine.
  • suction air is also constantly required in order to suck off the fiber dust which continuously occurs during the rewinding process.
  • the Saugluft entrance the jobs of such textile machines is exacerbated when, for example, after a yarn breakage or a controlled cleaner cut the accumulated on the cross-wound yarn end must be picked up by a workstation's own suction and transported to a yarn splicing device.
  • a particularly high intake air requirement, which often overstrains the performance of the machine's own suction air system, is particularly present when, for example, after a batch change a large number of jobs to be re-pooled simultaneously.
  • a pneumatic vacuum When operating the jobs of open-end rotor spinning machines in addition to electrical energy and constantly a pneumatic vacuum is required. That is, in the rotor housing of the open-end spinning device of the workstations of such textile machines, a so-called spinning vacuum must constantly prevail, which ensures during the spinning operation that the dissected from an opening roller of a master fiber strand single fibers are fed via a Faserleitkanal pneumatically in the spinning rotor, where be rotated from the spinning at high speed spinning rotor to a thread.
  • open-end rotor spinning machines In order to shorten the time required for the workstations of an open-end rotor spinning machine to run properly again after a power failure or a batch change, open-end rotor spinning machines have been developed in the past which have self-sufficient work stations. That is, the jobs of such open-end rotor spinning machines are able to automatically spin after a spin interruption without the help of an operating unit.
  • the suction of the Saugluftstrom can be increased by the speed of the drive motor of the Saugluftaggregates to reach a maximum speed, wherein the speed of the drive motor is controlled by monitoring the vacuum level in the Saugluftstrom.
  • the DE 43 38 283 A1 and the JP H09 21021 A reveal textile machines in which the jobs are started gradually.
  • the invention has for its object to develop a method and a cheese-producing textile machine for performing the method, which can be ensured that it is at a mass start of all jobs or a mass start a variety of jobs of an open Rotor spinning machine, which may be required, for example after a batch change or after a power failure, does not come to the occurrence of disturbances due to bottlenecks or overloads.
  • This object is achieved in that the jobs affected by a mass start of all jobs of the textile machine or at a start of a variety of jobs of the textile machine jobs are started successively by the switch-on for the following jobs on the first job each by a minimum period of 1 ms is delayed compared to the previously started job.
  • the presence of all necessary conditions for the start of the jobs is monitored and in their absence, the turn-on are each additionally additionally delayed with respect to the minimum time until these conditions for the next successful start again.
  • the inventive method avoids that in a first start phase of the jobs, the communication links are overloaded by simultaneously differentiated communication between the central control unit and each of the jobs done. While a simple broadcast command that is distributed equally to all workstations does not yet result in congestion, it is problematic to send corresponding responses from the workstations to the central control unit over the data bus at the same time. Furthermore, by the successive lowering of the stored in their creel lifted off cheeses on long machines their placement equalized on their drive rollers and avoided a possibly not insignificant oscillation. Finally, a sudden rash in the energy supply is suppressed.
  • the monitored conditions include the power supply, the pressure and Saugluftrgna and / or communication technology, the Saugluftrgna already belongs to the phases following the first phase, which is not already available for a high number of jobs anyway, but in groups at the same time can be demanded.
  • the cheese-producing textile machine according to the invention for carrying out the method according to the invention has a multiplicity of individually drivable, autonomously operating work stations with workstation-specific control devices and via a central control unit.
  • the central control unit has a switching device on which a mass start of all jobs of the textile machine or a mass start a variety of jobs of the textile machine can be initiated and the switching device or the workstation's own control devices are designed so that the affected jobs are started successively by the turn-on for the on the first job following jobs is delayed in each case by a minimum period of 1 ms compared to the previously started job.
  • the inventively provided minimum period of 1 ms already leads to the equalization of otherwise simultaneously occurring processes. This already begins with the fact that the lowering and setting down of the cheeses, which takes place in a first step, does not lead to a considerable oscillation of the machine due to simultaneity.
  • the successive communication by means of the machine bus avoids overloading the communication links. Energy and compressed air requirements are also equalized.
  • the generation of the power-up sequence can be done according to claim 9 and 10 either centrally in the central control unit or decentralized in the workplaces.
  • the delay of the start signal at the respective workstations is advantageously calculated from the product of an individual size of the workstation and the minimum time span. If the generation of the power-up sequence takes place only in the workstations, a broadcast signal is first sent to all workstations by the switching device of the central control unit. As a result, the determination of the individual delay of the start time is initiated in the workstations and then the transmission of the response signals is staggered via the data bus.
  • an individual delay time is calculated depending on the job number for each job. This means that the minimum time span is multiplied by the job number, which ultimately leads to a kind of turn-on shaft along the textile machine.
  • an almost arbitrary deviating sequence of the switch-on pulses for example one after the other odd-numbered and then even-numbered jobs can be selected.
  • the monitored conditions include the power supply, the pressure and Saugluftrgna and / or communication technology, the Saugluftrgna already belongs to the phases following the first phase, which is not available simultaneously for a large number of jobs, but in groups at the same time can be demanded.
  • Fig. 1 is schematically in front view of a cheese-producing textile machine, in the embodiment, an open-end rotor spinning machine 5, shown.
  • Such textile machines have between their end frames 31, 32 a plurality of identical, hereinafter with reference to Fig.2 described in more detail, self-sufficient work stations 1 and have a central control unit 10 and a machine-own suction system 20th
  • a vacuum source 30 of the Saug Kunststoffstrom 20 is disposed in one of the end frames of the open-end rotor spinning machine 5, wherein the vacuum source 30 by an electro-motor drive 29 which is defined by means of a frequency converter with respect to its speed adjustable, is applied.
  • the drive 29 or the associated frequency converter is connected via a control line 35 to a central control unit 10 of the textile machine 5, which has a switching device 12, via which the operator can input control commands into the central control unit 10.
  • the central control unit 10 is also connected via a bus system, preferably via a CAN bus 28, to the workstation's own control devices 25 of the numerous independently operating work stations 1.
  • the textile machine 5 is also equipped with a movable along the workstations 1 operating unit 7, preferably a so-called cleaning and changer car equipped.
  • this cleaning and changer cart 7 ensures that finished cheeses are transferred from the creel 22 of the workstations 1 to a (not shown) Spulenabtransportband the textile machine 5 and new empty tubes in the creel 22 of the jobs 1 are changed.
  • the Fig. 2 shows in perspective one of the many largely self-sufficient working places 1 in Fig.1 schematically illustrated open-end rotor spinning machine. 5
  • Such a workstation 1 has, as is known per se and therefore only shown schematically, always an open-end rotor spinning device 2 as well as a winding device 3.
  • a piecing 16 is arranged, which accumulated after a yarn break or a controlled cleaner cut on the cheese 8, by a pivotally mounted, under groutbeetzschlagbare suction nozzle 4 of the cheese 8 retrieved thread 9 and prepares the thread end for rebirth.
  • such a workstation 1 has a thread withdrawal device 27, which takes over both the removal of the thread 9 from the open-end spinning device 2 during the regular spinning operation, as well as the re-spinning for a defined return of a prepared thread 9 in the open-end spinning device 2 provides ,
  • the winding device 3 has, as usual, a creel 22 for rotatably supporting a cross-wound bobbin 8, a preferably powered by a reversible single drive 36 drive drum 23 and a Fadenchangier affection 24 which is driven by means of a stepping motor 37, for example.
  • a thread centering device in the form of a pivotably mounted centering plate 11 can be arranged in front of the thread-changing device 24.
  • the workstation 1 is also equipped with a thread monitor 26, a paraffining device 17 and a pneumatically actuable storage nozzle 40, which stores excess thread length during run-up of the job 1 and thereby ensures that the yarn produced in the open-end spinning device with a proper Winding tension is wound up.
  • Both the storage nozzle 40 and the pivotally mounted suction nozzle 4 are connected via a defined controllable device 13 to the machine's own suction system 20 of the open-end rotor spinning machine 5. That is, the suction nozzle 4 and the storage nozzle 40 can be acted upon when required with negative pressure.
  • the pivotally mounted suction nozzle 4 is also adjustable by means of a stepping motor 6 between a thread receiving position lying in the region of the winding device 3 and a yarn transfer position lying in the region of the spinning device 2.
  • an authorized operator at the switching device 12 of the central control unit 10 enters a corresponding command for a mass start of the work stations 1.
  • the central control unit 10 then sends via the bus system 28 corresponding start pulses to the workstation's own control devices 25, the numerous start pulses are each delayed by a minimum period of 1 ms, preferably 15 ms, sent to the individual jobs 1.
  • the delay time compared to the first start signal is dependent, for example, on the job number.
  • the central control unit 10 when the central control unit 10 is commanded to re-start the open-end rotor spinning machine by an operator, the work stations 1, initiated by a switching means 12 of the central control unit 10, spin in turn, offset by a delay time of 15 ms from their predecessor , new.
  • the switch-on pulses run in the case of using the workstation number for the delay sequence like a wave through the open-end rotor spinning machine.
  • a broadcast command could also be issued by the central control unit 25 or the switching device 12, which initiates the determination of the individual switch-on delay in the workstations.
  • the Switch-on pulses delayed from the set minimum time period until the conditions for the next start are present again.
  • a prior determination of the minimum period of time for example, to 1, 5 or 15 ms, results from known conditions that would directly lead to interference in an overlap of the turn-on, such as in the communication or energy or compressed air supply.
  • the further phases of the piecing process such as the thread search and the actual piecing are largely independent of the first phase and include, as already known, a delay which is essentially dependent on the sufficient suction air supply. For example, a maximum of 12 or 24 spinning stations can be adequately supplied with suction air at the same time, so that staggering of the initiation of the piecing phases following the first phase can also take place in groups and with a greater time interval than in the claimed minimum period of time.
