Definitions

  • the invention relates to a method and device for restoring the spinning operation after an interruption at a spinning position of an OE spinning machine, which has a plurality of spinning positions, each of which has a spinning element, which has an autonomous mobile piecing unit and an autonomous mobile, a full package against one empty sleeve replacing bobbin changing unit is equipped.
  • Mobile devices are known for changing cross-wound bobbins on OE spinning machines, which carry out the changing process in such a way that they separate the thread that still comes from the spinning element onto the cross-wound bobbin, hold it in a suction tube, suck in the trailing thread and the full bobbin replace with an empty sleeve.
  • the thread that continues to run into the suction tube is then placed on the sleeve, with a thread reserve possibly being wound onto the sleeve end first.
  • the mobile device then transfers the thread to the spinning position of the OE spinning machine.
  • the disadvantage here is that the thread must run onto the package until the changing device, which serves a large number of spinning positions, reaches the spinning position which has reached the specified length of thread, the specified number of bobbins or the corresponding cross-bobbin diameter. A precisely measured thread length can therefore not be wound onto the package.
  • Combined changing and piecing units have also been developed, with which the spinning device is spun with the help of a foreign thread after a package change.
  • the spun thread is taken up by a suction tube and from there placed on the sleeve on which the new package is to be wound up.
  • the piecing and changing capacity of such a combined device is low, however, because the bobbin changing unit must inevitably remain inactive during the removal of a thread break during the spinning process, that is, it cannot operate at other spinning positions at the same time.
  • the change capacity is particularly low if the changer has a device for preparing the thread start on the finished package and the cycle time for a bobbin change is thereby extended. It is therefore often necessary to have several combined changing and piecing units working on one OE spinning machine, which is very complex and cumbersome.
  • the bobbin changer carries tubes which are already prepared for spinning by having already wound an initial length of the thread. After this so-called starter spool has been clamped, the spinning takes place as if a thread break had occurred. This system has been used very successfully so far. In the event of a batch change, however, there must be a predetermined amount of the yarn which is to be spun with the new batch. This particular amount of yarn is initially to provide. Only then can the starting spools be wound and only then is it possible to carry out the spool change or batch change at the individual spinning positions one after the other.
  • the invention has for its object to restore the spinning operation reliably and quickly after a thread break or a bobbin change.
  • this object is achieved in that by means of the piecing unit with a first piecing program for eliminating a thread break occurring during the spinning operation, the end of the thread is automatically withdrawn from the bobbin, guided to the spinning element of the spinning station, applied to the spinning fibers present or fed there, then continuously pulled off the spinning element as a re-spun thread, transferred to the spinning station and wound onto the package, and that on the occasion of a bobbin change carried out by the autonomous mobile bobbin changing unit, a signal is triggered which the mobile autonomous piecing unit for stopping at the spinning station and for starting a second piecing program caused, with the help of which after the bobbin change, an auxiliary thread is drawn from a supply bobbin, passed to the spinning element of the spinning station and applied to existing or fed spun fibers, then as re-spun The thread is continuously withdrawn from the spinning element and passed to the sleeve while eliminating the auxiliary thread piece, transferred to the spinning station and continuously wound on the sleeve to form
  • the signal is triggered by the bobbin changing unit after the bobbin change has ended, passed on to the winding unit and transmitted from the winding unit to the piecing unit.
  • the signal is triggered by the spinning station when an empty bobbin tube is received and passed on to the piecing unit.
  • the signal can also be triggered by the piecing unit observing the content of the bobbin frame and taking the presence of an empty bobbin tube clamped in the bobbin frame as an occasion to stop at the spinning position and / or to start the second piecing program.
  • the signal is triggered by a yarn length counter which is reset to zero when a specified yarn length of the cheese package and / or the bobbin changing process caused thereby is reached.
  • the piecing unit advantageously interrogates the yarn length counter and adjusts itself to the second piecing program when the yarn length counter is at zero.
  • the yarn length counter can, for example, be arranged at a central point on the OE spinning machine.
  • the piecing unit can be in constant connection with the thread length counter via a trailing line or via sliding lines with sliding contacts. But there are also other ways of arranging counters and active connections.
  • the method for carrying out the method is that the piecing unit has a first piecing program and devices that can be switched after this first piecing program for piecing a thread returned from the cross-wound bobbin to the spinning element and a second piecing program and, according to this second piecing program, switchable devices for piecing one from a supply reel to the spinning element S. returned auxiliary thread and switching means responsive to a thread break or its consequences for starting the first piecing program and switching means responsive to a bobbin change or its cause or its consequences for starting the second piecing program.
  • the signal transmitter advantageously has a switch coupled to a sequence control device of the bobbin changing unit.
  • the signal transmitter has a sensor which checks the coil frame for the presence of an empty coil sleeve and which can advantageously be arranged on the piecing unit.
  • the OE spinning machine or the spinning station has a yarn length counter which has active connections with the switching means for selecting and / or starting the second piecing program, which can be activated as soon as the yarn length counter has reached the specified yarn length of the cheese and / or is set to zero again on the basis of the reel change process caused thereby.
  • the spinning box 6 containing a rotatable spinning element feeds a sliver 7 originating from a sliver can 7' and, after an OE spinning process, spins a thread 8 'which is drawn through a draw-off tube 8 from the spinning box 6 is subtracted.
  • a feed drive 9 continuously pulls the sliver 7 into the spin box 6.
  • the fiber sliver is dissolved into individual fibers by a dissolving device, not shown here, driven by a dissolving drive 10.
  • the fibers collect again and reach the open end of the thread 8' rotating about its longitudinal axis.

  • a puller 37 is pivotable about the pivot point 37a. It serves to pull down a thread sucked in by the suction nozzle 4 in order to insert it into a cutting and untwisting device 41 and into a thread feeder 42. For this purpose, the puller 37 pivots downward from an upper position into the position shown, taking the thread with it.

With the thread sucked in, it then pivots into the position shown in FIG. 2, the auxiliary thread 33a being transferred to the take-off roller 39. By placing the pinch roller 40 against the take-off roller 39, the auxiliary thread 33a has been pinched. Thereafter, the guide lever 38 presses the auxiliary thread 33a towards the center, so that the puller 37 can grip it from the position shown in solid lines in FIG. 2.
