Definitions

  • the invention relates to a method and a device for the temporal optimization of a work schedule at individual workplaces of textile machines, according to the preamble of claims 1 and 15.
  • Uniformly wound yarn lengths can be achieved in an open-end spinning process, also known as a rotor spinning process, by measuring the yarn lengths during the winding process by means of a length measuring unit and by interrupting the spinning process per spinning station for the bobbin changing process when a predetermined target yarn length is reached.
  • the changing process can be carried out either manually or by means of stationary thread attaching and bobbin changing devices which are provided for each spinning station or by means of corresponding devices which move along the spinning stations.
  • the disadvantage of the last-mentioned method step is the still relatively long waiting times of the individual spinning stations until the change is completed, in particular when it is necessary to change almost several bobbins which may be at a distance from one another.
  • German Offenlegungsschrift No. 30 30 504 proposed to control a bobbin changing device by means of a length measuring device in combination with a computing unit to the spinning station at which the bobbin has at least approximately reached the desired length.
  • the length measuring device determines the yarn length of a number of spinning positions assigned to it and reports these lengths continuously to the computing unit in which these length values are stored and each compared with the target value.
  • the computing unit commands the bobbin changing device as a precaution to this bobbin, so that the bobbin changing process is triggered when the yarn length corresponding to the setpoint is reached.
  • the removal of the full bobbin is followed by the insertion of an empty tube and the attachment of the yarn end separated from the full bobbin.
  • the removal of the full bobbin and the insertion of the empty tube, as well as the attachment of the yarn end to the empty tube, is also called “doffing” and the device which carries out this "doffing” is called “doffer” for short.
  • the maximum length difference mentioned corresponds to the long travel time required for the doffer, including the time for the doffing itself.
  • the object of the invention is therefore to remedy this disadvantage.
  • the invention solves the problem in terms of method and device in the manner characterized in claims 1 and 15.
  • a changing device 10 travels along a textile machine (not shown) for producing yarn packages with predetermined desired yarn lengths (shown with a dash-dotted line) in order to form one the time described later to change the bobbins marked with the numbers 1 to 8 and belonging to the winding process of the textile machine after reaching the desired yarn length against empty tubes (not shown).
  • a yarn length sensing element 111 to 118 which is known per se from DOS 3030504 and is assigned to each bobbin, continuously measures the length of the yarn to be wound and emits a signal corresponding to this length to a computing unit 12. Furthermore, the computing unit is assigned a positioning element 131 to 138, e.g. One limit switch each, signals the position of the changing device.
  • t is a time which is required to reach the predetermined desired yarn length
  • t R is a time which is required to wind up a predetermined remaining yarn length
  • t is a waiting time for a bobbin which has stopped after reaching the desired yarn length until the start of change.
  • a time required for the travel of the changing device is denoted by t S , the time required for the waiting of the changing device until the bobbin change and t D the time required for the bobbin change.
  • the arithmetic unit 12 is continuously scanned by the yarn scanning elements 111 to 118 while the individual bobbins 1 to 8 are being generated Yarn lengths signaled.
  • the computing unit 12 compares the bobbin time of all the bobbins that have reached the time range of the remaining yarn length t R with the respective travel time until the desired yarn length is reached Change device to these coils and selects the combination for three coils that results in the shortest possible waiting time t u for the three selected coils.
  • the travel time of the changer 10 from the coil 1 to the coil 4 with t s , from the coil 4 to the coil 7 with t s and analogously between the coils 7 and 5 with t S7 -5 is called.
  • the remaining times relating to a specific coil are provided with an index corresponding to the coil number.
  • t W4 , t W7 and t U5 would not be zero, but the time t U5 would be as short as possible.
  • the times t ' R4 , t' R7 and t ' R5 accordingly differ from the times 4 t R , t R7 and t R5 (all in FIG. 3) and are determined by the optimization O 2 .
  • the computer determines that priority has been given to another change sequence in the meantime If, for example, in order not to change the coil 5 but the more distant coil 8 after changing the coil 7, the computer changes the sequence.
  • the computer has determined that the remaining yarn length t R8 comes to an end shortly after the remaining yarn length t R that a new change sequence 5 A I , in which the bobbin 8 after the bobbin 7 and before the coil 5, the total waiting time t U results, namely the time t U5 .
  • the times for this change order are shown in FIG. 5 with solid lines.
  • dashed lines show the chronological course of an alternating order A, from which it can be seen that in such an order the sum of the times t ' u and t U8 is greater than the time t U5 , the order AI.
  • the aforementioned optimization method can also be used for a rotor spinning machine, on which the bobbins 1 to 8 are additionally produced with a predetermined excess length that goes beyond the desired yarn length.
  • the waiting time t U following this excess length t Ue is the mean time after the bobbin has stopped, ie after the time t Ue has elapsed until the bobbin is changed and the thread is reattached, be it manually or mechanically.
  • a computer 121 (FIG. 1) of all the bobbins which have reached the time range of the remaining yarn length t R compares the remaining take-up time up to and with the time t Ue for reaching the maximum excess length with the respective travel time of the changing device to these coils and selects the combination for three coils that results in the shortest possible time t Ue for the three selected coils.
  • FIG. 7 An example of such a variant is shown in FIG. 7, in which a bobbin changer 101 changes the bobbins 4, 7 and 5 in succession from the position shown in FIG. 1 in accordance with the change order A III .
  • Optimization 0 4 has previously detected the remaining yarn lengths t " R4 , t" R7 and t “ R in such a way that the bobbins 4 and 7 are produced without and the bobbin 5 with excess length.
  • a new change priority is selected by the computer 121 in order to first change the coil 8 and then the coil 5 according to a change order A IV after changing the coil 7.
  • This sequence of changes is determined beforehand by optimization 0 5 .
  • the computer 121 also triggers a signal for this corresponding winding unit after the time t Ue has expired and temporarily switches this winding unit off from the optimization program.
  • the resumption into the optimization program takes place, for example, through manual signaling (not shown) by the operator after changing the bobbin and attaching the thread to the corresponding spinning position. Attaching the thread can be understood as either attaching to the new bobbin with the spinning process not interrupted at this spinning position or re-spinning with an interrupted spinning process.
  • Another variant of the use of the optimization method is that the time of cleaning the rotors of the individual spinning stations after the spinning station is stopped is optimized by means of a yarn length measuring unit belonging to a computer 122.
  • the optimization method works according to the variant shown and described with FIGS. 2, 4 and 5.
  • the recorded times t R of the remaining yarn lengths correspond to the remaining yarn lengths before the time of cleaning and the waiting times t are waiting times after stopping the spinning process per spinning station until the time of cleaning.
  • a second variant of the use of the optimization method for cleaning the rotors of the individual spinning positions consists in cleaning within a time range subsequent to a predetermined target time for cleaning, e.g. after half the target yarn length is reached.
  • the optimization process selects e.g. three spinning positions, the winding times of which are within a time t of a remaining yarn length before reaching the stated point in time.
  • This optimization method works essentially according to the variant shown and described with FIGS. 6 and 7.
  • the end of the time t R corresponds to the target time for cleaning the rotor and the time t Ue shown in FIG. 7 corresponds to the time range within which the rotor cleaning must take place.
  • the spinning station is stopped for the time t.
  • the rotor is cleaned before re-spinning.
  • the changer 10 101 a vehicle Speed that allows you to travel along 200 spinning positions in 2.5 minutes and takes 20 to 30 seconds for the bobbin changing, cleaning and re-spinning process.
  • the claimed method is not only limited to the application for changing bobbins on rotor spinning machines. It can basically be used for all textile machines in which twine bobbins are produced with predetermined nominal yarn lengths and in which the bobbins are changed after reaching this nominal yarn length by a device controlled at the work station.
  • the invention thus relates to a textile machine with a majority of work stations, a mobile maintenance device, a roadway for the device and a control device.
  • the machine is provided with a data transmission system in order to convey operating status data from the workstations to the control device, position data from the maintenance device to the control device and control data from the control device to the maintenance device.
  • the operating status data represent the operating status of the individual work stations, the position data the position of the maintenance device relative to the work stations.
  • the control data control the movements of the maintenance device along the road.
  • the control device is arranged such that the control data are produced in accordance with the operating state and position data obtained.
  • the invention further relates to a control method for a Textile machine with a majority of jobs, a mobile maintenance device, a roadway for the device and a control device.
  • the operating states of the various work stations and the position of the maintenance device relative to the work stations can be determined and communicated to the control device as data.
  • the movements of the maintenance device along the road can be controlled by the control device in accordance with the determined operating states and the position.
  • the textile machine could e.g. an OE spinning machine, a ring spinning machine or a winding machine.
  • the determined operating states could be run times, and / or normal operation / malfunction and / or bobbin fullness (wound yarn lengths.
  • the control device can be arranged in such a way that the movements of the maintenance device are optimized according to a program.
  • the optimization criteria of the program can be the minimum total time of the workflow represent the maintenance device or at least take it into account, whereby under "workflow" preprogrammed maintenance work must be included in a majority of workplaces.
