Definitions
- the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 12.
- Such a method and a device for carrying out the method are known from WO 93/17949.
- the known device has a winding turret with two winding spindles which are brought alternately into the winding area and into a changing area by rotating the winding turret, the full bobbins being pushed off in the changing area and then the empty tubes being pushed onto the unloaded winding spindle.
- the winding spindle located in the winding area is referred to as the operating spindle and the winding spindle located in the alternating area is referred to as the rest spindle.
- the full bobbins are removed from the idle spindle at the end of a winding trip and exchanged for empty tubes, since the thread continues to feed.
- the winder is equipped with an automatic control device for carrying out automatic bobbin changes, as described, for example, in the prospectuses Aut 14 (d) "Doffer WD5" or Aut 15 (d) "Doffer WD9 "from Barmag AG is known.
- Such an operator control has a bobbin mandrel for taking over the finished spinning bobbins v of the idle spindle and a second mandrel for supplying the discharged bobbin spindle with new empty tubes.
- winding spindles are relatively narrow due to the compact design of such winding machines and the spools on the operating spindle, which increase in diameter at the usual high winding speeds, grow against the full bobbins still on the idler spindle, especially when winding threads and Yarns with a higher titer, for example of carpet yarn, high winding speed for a rapid increase in the bobbin diameter and consequently for rapid successive bobbin changes with relatively low intermediate times between the individual changes.
- the object of the invention is now to develop the known method for changing bobbins according to the preamble of the claim in such a way that the bobbin change no longer takes place in a more flexible manner and with a changing time adapted to the yarn to be wound up, so that the bobbin is entrusted with the bobbin change Automatic control device (doffer) is only held as short as possible at the winding point.
- a margin for the coordination between the individual spool heads and the doffer carrying out the bobbin change is achieved for the bobbin change, so that the automatic control device is no longer held at the respective winding position as absolutely necessary.
- the sequence of the bobbin change is now determined by the machine or doffer control and is dependent on the parameters specified in claim 2.
- the spool change is initiated depending on the availability of the doffer at the spool point signaling the spool change.
- the start of the change range is thereby determined that the idle spindle reaches its change position at the earliest when the operating spindle is moved into the winding position at the start of a new winding cycle, although a small amount of time that can be used to initiate the movement sequences may be advantageous.
- the beginning of the changing range is 180 ° behind the turret position at the beginning of the turning process.
- the size of the change range should include an angle of rotation of at least 15 ° and at most 75 °, preferably from 30 ° to 60 °.
- the winding spindle to be doffed enters the changing area of the operating machine or its changing devices by monitoring and control devices of the winding spindle precisely aligned at least from the start.
- the control of the operating machine or its changing devices can take place depending on the machine control supplied control signals of the respective winding head or depending on control signals of the automatic control device.
- a free operating machine is signaled a short time before the winding turret swivels into the changing area when the bobbin is changed, so that it is called to the winding head in question.
- the finished bobbins are pushed off the bobbin lockers.
- the spool vendor of the operating machine (doffers) carrying the empty tubes is adjusted and the idle spindle, which is now moved, is adjusted until the axis is aligned and the empty tubes can be pushed from the spool mandrel to the unloaded spool spindle.
- the winding mandrels of the doffer are adjusted by the machine control of the respective winding head for alignment with the rest spindle.
- the bobbin change can be carried out - depending on the particular circumstances such as winding speed, thread titer, bobbin dimensions and the like - without interfering with the rotary drive of the bobbin turret when changing the bobbin.
- the doffer is always kept in a precise changing position, evaluating the changing position data of the moving spindle. its winding mandrel for receiving the full bobbins tracks the rest spindle.
- the bobbin change and the loading of the bobbin spindle with empty tubes takes place without a fixed time, as soon as an operator control is available. In the case of a plurality of winding machines and automatic machines, this can save investment costs, since only a smaller number of automatic machines may be required.

- the sensor 123, 124 can be installed in such a way that the magnetic field lines of the magnet 124 rotating with the winding turret 102 run vertically when the winding rotor 102 is in the zero position explained above, and accordingly the or anchoring one of the sensor elements 123A, 123B with its lengthwise extension transverse to the field lines of the machine frame 101 secured against rotation is that its side surfaces facing the magnetic poles 124A, 124B intersect the field lines at an angle of 90 ° when the axes of rotation of the two winding spindles (104, 105) lie one above the other as shown in FIG. 7.
- the arrangement shown in FIG. 9 is preferred, in which the magnetic field lines in each position of the turret 102 run parallel to a plane defined by both winding spindle axes, consequently that Sensor element 123A is anchored on the machine frame 101 with its longitudinal extension transverse to the field lines so that it is secured against rotation in such a way that, in the zero position of the turret 102, its magnetic lines 124A, 124B facing the plane of the magnetic poles 124A, 124B extending through the axis of the spindle axes Cut an angle of 90 °.
- two sensor elements 123A, 123B are preferably provided according to the invention, one of which (123A) is fastened in the manner described above and the second sensor element 123B opposite the first (123A) is rotated by an angle of 90 ° with the rotor axis as the axis of rotation.
- a magnetic field sensor and its structure and arrangement in the turret 1 was shown in the preceding description as a sensor device 123 for detecting the angular position of the rest spindle, the invention is not limited to the specific embodiment of the measuring device. Rather, other transducers can also be used, by means of which the changes in the angle of time of the respective rest spindle 1 or both winding spindles 104, 105 can be continuously detected and made available in analog or digital format. For example, other known rotary angle encoders can be used or measuring devices that evaluate the switching impulses of the stepping motor for the rotary drive 103 of the turret 102.
