Definitions
- the invention relates to a method and a device for temporally optimizing a work event at individual workplaces of textile machines, according to the preamble of patent claims 1, 2 and 8.
- Evenly wound yarn lengths can be spun in an open-end spinning process, e.g. B. rotor spinning process, can be achieved in that the yarn lengths are measured during the winding process by a length measuring unit, and that when a predetermined target yarn length is reached, the spinning process per spinning station is interrupted for the bobbin changing process.
- an open-end spinning process e.g. B. rotor spinning process
- the change 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.
- Such a device is known from European Patent Application No. 0 047 743.
- An open-end spinning machine is shown and described therein, in which a bobbin changing device and a thread attachment device are commanded to this spinning station by means of a control device on the basis of a request signal from a corresponding spinning station.
- the changing device as well as the thread attaching device are each guided on a separate rail in such a way that they can be controlled past one another at the corresponding spinning positions.
- the use of the two devices is coordinated taking into account their positions and the position of the requesting spinning station.
- German Offenlegungsschrift No. 3 030 504 it is proposed in German Offenlegungsschrift No. 3 030 504 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 briefly “dotten ” and the device which carries out this “doffing” is briefly called “doffer”.
- the maximum length difference mentioned corresponds to the length of time required for the doffing including the time for the doffing itself.
- the disadvantage of this method is the long waiting time until the bobbin changing process with only short travel times required. This disadvantage has an impact on the frequency of changing bobbins.
- 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, 2 and 8.
- a changing device 10 travels on a textile machine (not shown further) for producing yarn bobbins with predetermined ones Desired yarn lengths along (shown with a dash-dotted line) in order to change the bobbins marked with the numbers 1 to 8 and belonging to the winding process of the textile machine at a later time, after reaching the desired yarn length against empty tubes (not shown).
- a thread length sensing element 111 to 118 known per se from DOS 3 030 504, 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 provided by a positioning element 131 to 138, known per se, associated with each coil, e.g. One limit switch each, signals the position of the changing device.
- t is a time which is required to reach the predetermined target yarn length
- t R is a time which is required to wind up a predetermined remaining yarn length
- t u is a waiting time for a bobbin which has stopped after reaching the target yarn length 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 with t w and the time required for the bobbin change with t ⁇ .
- the computing unit 12 is continuously signaled the yarn lengths scanned by the yarn scanning elements 111 to 118 during the production of the individual bobbins 1 to 8.
- 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.
- t W 4th , t W 7 and t U 5 not be zero, the time t U 5 however as small as possible.
- the times t 'R 4th , t ' R 7 and t ' R 5 accordingly deviate from the times t R 4th , t R 7 and t R 5 (all in Fig. 3) and are detected by the optimization O 2 .
- the computer determines after the end of a coil change that priority must be given to another change sequence in the meantime, 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.
- O 3 the computer has determined that the remaining yarn length t R 8th so shortly after the remaining yarn length t R 5 It comes to an end that a new change order A ', in which the coil 8 is changed after the coil 7 and before the coil 5, gives the overall shortest waiting time t U , namely the time t U 5 .
- the times for this sequence of changes are shown in FIG. 5 with solid lines.
- 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 winding 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 one after the other from the position shown in FIG.
- the optimization O 4 previously has the remaining yarn lengths t " R 4th , t “ R 7 and t “ R 5 recorded in such a way that the coils 4 and 7 are produced without and the coil 5 with an 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 When the bobbins are changed manually, 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 u 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 is that the cleaning takes place within a time range after a predetermined target time for the cleaning, for example after half the target yarn length has been reached.
- the optimization process selects z. B. from three spinning positions, the winding times are within a time t R of a remaining yarn length before reaching the specified time.
- the distances shown in FIGS. 2 to 8 and corresponding to the different times are not to scale.
- the changer 10; 101 a driving 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.
