Definitions

  • the present invention relates to a method for operating a spinning or winding machine with a plurality of workstations arranged next to one another, each of the workstations having a thread delivery device, in particular a spinning device, for delivering a thread, a withdrawal device for withdrawing the thread, a winding device with a winding drive for winding of the thread on a bobbin and a thread store for temporarily storing a thread loop formed during piecing.
  • the invention also relates to a corresponding spinning or winding machine, in which a control device for controlling the winding drive is also provided.
  • a thread supplied by a spinning device or a pay-off bobbin is drawn off by means of a withdrawal device and wound onto a bobbin by means of a winding device. If a thread breakage or a cleaner cut occurs at one of the work stations, the work station in question on the spinning or winding machine is shut down. Then the thread has to be started again, i.e. either spun or spliced, and the work site concerned has to be put back into operation. When the work station is started up, there are speed differences between the delivery device or the take-off device and the winding device, so that temporary excess lengths of the thread arise. These must be taken up in a thread store, otherwise the bobbin would be wound up without the necessary winding tension and faulty bobbins would be generated.
  • this temporary excess length can be recorded in a thread store of the maintenance device.
  • the jobs of the spinning or The winding machine is designed as self-sufficient or at least partially self-sufficient workplaces, so such a thread store must be provided at each individual workstation.
  • the thread stores are generally designed as pneumatic thread stores that are subjected to negative pressure. These have a relatively high air consumption, since the thread stores have to be subjected to negative pressure during the entire piecing process.
  • the DE 10 2006 047 288 A1 describes a textile machine in which a pneumatic thread store is provided at each individual work station.
  • a pneumatic thread store is provided at each individual work station.
  • the thread stores individually lockable so that they can be separated from the negative pressure as soon as they are no longer needed.
  • the loosening of the thread loop is monitored by sensors and the thread storage device is depressurized as soon as the thread loop has left the thread storage device. This can reduce the vacuum consumption of the textile machine.
  • the provision of a sensor at each individual workstation is costly.
  • the object of the present invention is to propose a method for operating a spinning or winding machine and a spinning or winding machine which allow the winding speed to be timed in a simple and cost-effective manner when the work station is running up.
  • each of the workplaces has a thread delivery device, in particular a spinning device, for delivering a thread, a pull-off device for pulling off the thread, a winding device with a winding drive for winding the thread onto a bobbin and a thread storage device for temporarily storing a thread loop that occurs during piecing.
  • a thread delivery device in particular a spinning device, for delivering a thread
  • a pull-off device for pulling off the thread
  • a winding device with a winding drive for winding the thread onto a bobbin
  • a thread storage device for temporarily storing a thread loop that occurs during piecing.
  • a spinning or winding machine in particular an open-end spinning machine, in particular for carrying out the aforementioned method, has a large number of work stations arranged next to one another, each of the work stations having a thread delivery device, in particular a spinning device, for delivering a thread, a pull-off device for pulling off the thread, a winding device has a winding drive for winding the thread onto a bobbin and a thread storage device for temporarily storing a thread loop that occurs during piecing. Furthermore, a control device is provided for controlling the reel drive.
  • a lot-related, optimized run-up curve for the winding speed is determined by means of a control device at the beginning of a new lot at at least one of the work stations. This takes place in that the thread loop in the thread store is detected at the work site by means of at least one first sensor and a winding speed of the winding drive is set as a function of a signal from the at least one sensor.
  • the optimized run-up curve determined in this way is then given to other workplaces of the spinning or winding machine processing the same batch as a setpoint curve.
  • capturing or detecting the thread loop can both only the presence and a length of the thread loop can be detected by means of one or more sensors.
  • the bobbin When setting the winding speed, the bobbin should be accelerated as slowly as possible in order to avoid a jerky pull on the yarn and the bobbin jumping. This, however, creates relatively long thread loops, so that the entire length of the thread store must be used for storing the excess length of thread as far as possible. On the other hand, however, the thread loop should be dissolved again as quickly as possible in order to keep the negative pressure consumption at the work site as low as possible.
  • the winding speed is therefore preferably set during the run-up of the work station as a function of the signal (s) of the at least one sensor in such a way that the thread loop is broken up as quickly as possible when the bobbin is accelerated as slowly as possible.
  • At least one first sensor for detecting the thread loop in the thread store is arranged at at least one of the work stations.
  • the sensor is connected to the control device by means of a signal line.
  • the control device and / or a further control device is designed to set a winding speed of the winding drive as described above as a function of a signal from the at least one sensor and to determine a lot-related, optimized run-up curve for the winding speed.
  • the control device and / or a further control device is designed to control the winding drives of further work stations of the spinning or winding machine by means of the optimized run-up curve.
  • the work station is thus designed as a so-called pilot work station, at which a run-up curve of the winding speed optimized for a specific yarn section can be determined, with which the required winding tension is always maintained and a gentle winding acceleration is achieved.
  • this optimized run-up curve this has to be done Starting up the work station, if necessary, can be carried out several times with different controls of the winding speed and a check is made to see whether there are thread breaks or sagging threads. If the optimized run-up curve has been determined by means of the control device, for example the workstation control of the relevant workstation, then this can be transmitted either via a machine control or directly to other workstation controls.
  • the other work stations can then, for their part, set their winding speed according to the optimized run-up curve when starting up.
  • the optimized run-up curve can, however, also be saved so that it can be used later for settings at other workplaces. It is therefore not necessary to equip all work stations with expensive sensors in the thread store.
  • the spinning or winding machine can be equipped inexpensively as a result.
  • the loosening of the thread loop is detected by means of the first sensor.
  • the first sensor is arranged in an opening area of the thread store. For example, the sensor detects the thread loop for the first time when it is sucked into the thread store. If the sensor then detects the thread loop a second time when the thread loop is withdrawn from the thread store, this indicates that the thread loop has broken up. If the sensor delivers the signal that the thread loop is being opened, the vacuum supply to the thread store can already be shut off.
  • the winding speed is reduced from an increased winding speed to a regular winding speed as soon as the first sensor has detected the loosening of the thread loop.
  • the Winding speed can be reduced to the regular winding speed.
  • the optimal point in time determined in this way can then also be taken into account via the optimized run-up curve at the other workplaces that are not equipped with a sensor.
  • a length of the thread loop is detected by means of a second sensor.
  • a second sensor is advantageously arranged for this purpose, for example in an end region of the thread store.
  • the second sensor in the end area of the thread store does not deliver a signal or does not yet recognize the end of the thread loop, the bobbin can continue to accelerate slowly because the thread loop has not yet reached the end of the thread store. It is of course also conceivable to arrange several sensors in the thread store in order to determine the length of the thread loop more precisely and to adjust the winding speed even more sensitively.
  • a maximum length of the thread loop is detected by means of the second sensor and the winding speed is increased as soon as the second sensor has detected the maximum length of the thread loop.
  • the second sensor is also arranged in an end area or directly at the end of the thread store. As soon as the thread loop has reached the second sensor, which it registers and outputs a corresponding signal, there is a risk that the thread loop will become too long and reach into the vacuum channel of the machine. The winding speed is therefore increased in this case in order to return the excessively long loop to the desired size as quickly as possible.
  • the thread store of the at least one work station has electrical and mechanical interfaces for temporarily accommodating the at least one sensor or, during the process, the first and / or the second sensor are only temporarily arranged at the work station. This makes it possible to temporarily turn any job that has such interfaces into a pilot job.
  • a program for determining the lot-related, optimized run-up curve of the winding speed is stored in the control device and the program is activated when a run-up curve is to be determined at the at least one work station.
  • the program can only be provided in certain workplaces. However, it is also possible to provide each of the workstations of the spinning or winding machine with electrical and mechanical interfaces for a sensor and, for example, to store the program in each of the workstation controls or to install it there if necessary. It is thus possible to operate any workstation temporarily as a pilot workstation.
  • the lot-related, optimized run-up curve (s) are stored in a memory, in particular in an article management database. It is also advantageous if not only the optimized run-up curve but also the sensor data on which it is based are also stored. It is therefore also possible to check a run-up curve that has once been determined again at a later point in time.
  • the batch-related run-up curve (s) stored in the memory are called up when the same cooking section is produced again and the workplaces of the spinning or winding machine processing this yarn section are specified as a setpoint curve.
  • the run-up curve (s) therefore do not have to be determined again when the same yarn batch is produced again.
  • the stored run-up curves can also be used as the basic setting for new but similar yarn lots.
  • FIG. 1 shows a front view of a spinning or winding machine 1 in an overview.
  • the spinning or winding machine 1 has a multiplicity of work stations 2 arranged next to one another, which can be arranged on only one or also on both opposite longitudinal sides of the spinning or winding machine 1.
  • the workplaces 2 are presently arranged between two frames 9 in which central components such as central drives or functions can be arranged. In the present case, only a machine control 13 is shown as the central control device 17.
  • Each of the work stations 2 has, in a manner known per se, a thread delivery device 3, which can be designed as a spinning device or also as a pay-off bobbin.
  • the thread 5 delivered by the thread delivery device 3 is withdrawn by means of a withdrawal device 22 and, depending on the design of the spinning or winding machine 1, possibly via several further components or handling organs, fed to a winding device 4, where it is wound onto a bobbin 6, which is set in rotation by means of a winding roller 8.
  • each of the work stations 2 also has a work station controller 12 as a control device 17, which is connected to the machine controller 13.
  • a work station controller 12 as a control device 17, which is connected to the machine controller 13.
  • several work stations 2 can also be controlled by a common control device 17.
  • additional control devices 17, for example at section level, are provided.
  • the individual workplaces 2 of the spinning or winding machine 1 are designed here as so-called self-sufficient or at least partially self-sufficient workplaces 2. Such workplaces 2 are at least capable of automatically resuming the production process after an interruption.
  • the individual work stations 2 have a work station-specific attachment device, not shown, such as a piecing device or a splicing device.
  • a thread store 7 is provided at each of the work stations, which can accommodate an excess length of thread during the attachment, as on the basis of the Figure 2 will be explained.
  • At least one of the work stations 2 is at least temporarily designed as a pilot work station 11.
  • three work stations 2 are designed as pilot work stations 11, each of the three yarn sections 18 being assigned a pilot work station 11.
  • pilot work stations 11 could also be assigned to a yarn lot 18;
  • certain yarn sections 18 cannot be assigned any pilot workplaces, but setting values or run-up curves already determined earlier can be used.
  • FIG. 2 shows a schematic, partially sectioned side view of a work station 2 of a spinning or winding machine 1, which is designed as a pilot work station 11, during regular production operation.
  • both the take-off device 22 and the winding device 4 are each driven by means of an individual drive 24 and are each controlled by the workstation control 12.
  • the work station 2 has a suction nozzle 19, which in the present case is fixedly arranged at the work station 2 and by means of which a thread end that has run onto the bobbin 6 can be sought out.
  • the thread 5 runs through the suction nozzle 19, into which it enters through an opening 20 and exits again at a mouth (not designated).
  • the suction nozzle 19 could, however, also be pivotable be executed.
  • the suction nozzle 19 can be subjected to negative pressure via a negative pressure channel 21.
  • a shut-off means 23 can be used to shut off the negative pressure to the suction nozzle 19, so that suction is only applied to it when a thread 5 actually has to be searched for.
  • the pneumatic thread store 7 is shown, which is also connected to the vacuum channel 21 via a shut-off means 23.
  • the thread store 7 is thus only vacuumed when this is actually necessary for storing a thread 5.
  • both shut-off means 23 are in a closed position in which they shut off the connection to the vacuum channel 21.
  • the work station 2 shown here is designed as a pilot work station 11, in which a sensor 10 for detecting a thread loop 14 (see Fig. Figure 3 ) is arranged in the thread store 7.
  • a first sensor 10a is arranged in the mouth region 15 of the thread store 7.
  • the sensor 10a is connected to a control device 17, here the workstation control 12, via a signal line (dotted line).
  • Figure 3 now shows job 2 of the Figure 2 during start-up after a thread break or cleaner cut.
  • job 2 is initially shut down.
  • the thread 5 at the work station 2 must then be reattached and the work station 2 started up.
  • the take-off device 22 and possibly the delivery device 3 accelerate much faster than the winding device 4 with the comparatively heavy bobbin 6 to maintain the required winding tension.
  • the thread loop 14 initially grows further after it has been sucked in due to the speed difference between the winding device 4 and the drawing device 22 until the winding device 4 and the drawing device 22 have finally reached approximately the same speed and the thread loop 14 has reached its maximum length .
  • the first sensor 10a is now preferably arranged in the mouth area 15 of the thread store 7 that it only detects the end 14a of the thread loop 14 when it moves over the first sensor 10a.
  • the first sensor 10a has thus already detected the end 14a of the thread loop 14 for the first time and reported it to the workstation control 12. This therefore knows that the thread loop 14 has been successfully sucked into the thread store 7.
  • the point in time at which the thread loop 14 is opened can now be precisely detected and the winding speed can be reduced again at the precisely correct point in time. This is essential because an operation with increased winding speed after the thread loop has broken up 14 would inevitably lead to a thread breakage. Likewise, reducing the increased winding speed too early can lead to a reduction in the winding tension and thus to a bobbin 6 that is wound too loosely or incorrectly.
  • the loosening of the thread loop 14 is detected in the present case in that the first sensor 10a detects the end 14a of the thread loop for the second time when it passes over the sensor 10a.
  • the present work station 2 is designed as a pilot work station 11 by means of the first sensor 10a, an optimized run-up curve for the winding speed can now be determined.
  • start-up it can be observed whether thread breaks due to excessive thread tensions or faulty windings due to low winding tensions. If necessary, one or more sample coils can be wound, which are then examined to see whether they have the desired properties.
  • the run-up curve that is to say the run-up speed of the winding device 4 over time, is recorded, for example, by means of the control device 17, here the workstation control 12.
  • the point in time at which the increased winding speed is returned to the regular winding speed on the basis of the signal from sensor 10a can also be recorded exactly. In this way, after several run-up processes, the course of the winding speed can be optimized over time and an optimized run-up curve can be created.
  • optimized run-up curves are preferably determined several times during the winding of a bobbin in order to also detect different run-up behavior with different bobbin diameters. For example, optimized run-up curves for 5 - 10 different, graduated bobbin diameters can be determined. An optimized run-up curve is preferably determined at least for a minimum and for a maximum bobbin diameter. One or more sample coils can also be wound for this purpose.
  • an optimized run-up curve for the winding speed is determined in this way, for example by means of the control device 17, here the workstation control 12, then this can be transferred from the control device 17, here the workstation control 12 of the pilot workstation 11, for example directly to further workstation controls 12, not as pilot workstations 11 trained jobs 2 are transmitted. It is also possible that the optimized run-up curve is first transmitted to the machine control 13 and from there to the other workstation controls 12. For this purpose, the machine control 13 is in control connection with the workstation controls 12, as symbolized by the dotted lines. Alternatively, the run-up curve can of course also initially be stored in the control device 17 and later read out from it, in order then to be made available to further control devices 17, in particular to further workstation controls 12. Furthermore, the optimized run-up curve can of course also be determined by means of a control device 17 other than the workstation control 12.
  • the winding speed can now be optimally adjusted by means of the optimized run-up curve when running up at further work stations 2 not designed as pilot work stations 11, without a sensor 10a being required for this at each individual work station 2.
  • the optimized run-up curve is given to the other workplaces as a setpoint curve.
  • FIG Figure 5 shows another embodiment of a workstation 2 designed as a pilot workstation 11, in contrast to the workstation of FIG Figure 2 a second sensor 10b is provided in the thread store 7 in addition to the first sensor 10a. This is arranged in an end region 16 of the thread store 7.
  • a second sensor 10b By means of such a second sensor 10b, not only the loosening of the thread loop 14, but also the presence of the thread loop 14 in a certain area of the thread store 7 and thus the length of the thread loop 14 can be detected.
  • the second sensor 10b In order to accelerate the winding device 4 as slowly and gently as possible, it makes sense to produce a thread loop 14 that is as long as possible. If the second sensor 10b is arranged in the end area 16 of the thread store 7, as shown here, it can be detected whether the end 14a of the thread loop 14 has reached the end area 16 and thus the thread loop 14 has an optimal length. The slowest, just possible bobbin acceleration with which the optimum length of the thread loop 14 is achieved can thus be determined by means of the second sensor 10b by means of several run-up processes.
  • the sensor 10b is preferably arranged in the end region 16 of the thread store 7, but still somewhat spaced from the actual end of the thread store 7, which is marked by the shut-off means 23.
  • the second sensor 10b or a further sensor 10 to detect a maximum length of the thread loop 14.
  • the maximum length of the thread loop 14 is reached, for example, when the end 14a of the thread loop 14 has reached the shut-off means 23, since in this case there is a risk of the thread loop 14 jamming on the shut-off means 23.
  • the maximum length of the thread loop 14 can also be defined by reaching the vacuum channel 21, since there is then the risk that pieces of thread will get caught in the vacuum channel.
  • the sensor 10b is arranged at the point which marks the maximum length of the thread loop 14, for example directly next to the blocking means 23.
  • the control device 17, here the workstation control 12 knows that the maximum length of the thread loop 14 has now been reached. In this case, the winding speed is now increased in order to prevent further growth of the thread loop 14 and associated complications. Thus, not only the exact point in time of the loosening of the thread loop 14, but also the slowest possible point in time
  • the bobbin acceleration and the time at which the maximum length of the thread loop is reached are taken into account when determining the optimized run-up curve (s).
  • the at least one first sensor 10a and possibly the second sensor 10b do not necessarily have to be permanently arranged in the thread store 7, but can also be provided only temporarily in order to use a work station 2 as a pilot work station 11.
  • Fig. 6 shows a section of such a thread store 7 in a schematic detailed representation.
  • the thread store 7 of this workstation 2 has mechanical interfaces 26 and electrical interfaces 25 for receiving a sensor 10, 10a, 10b.
  • the workstation 2 can thus be converted into a pilot workstation 11 in a simple manner by attaching the sensor 10, 10a, 10b.
  • a corresponding control program is also stored in a control device 17, for example in the workstation control 12, which contains all the control and evaluation functions required for the function as a pilot workstation 11 and only needs to be activated by an operator .
