Definitions

  • the invention relates to a service unit according to the preamble of claim 1.
  • Open-end spinning machines are known to have a plurality of identical, juxtaposed jobs, each having a spinning device for producing a thread and a winding device for producing a cross-wound bobbin.
  • the jobs of such open-end spinning machines are usually supplied by automatically operating service units that intervene when an operating case occurs at one of the jobs.
  • Such an operating case is, for example, at a yarn breakage or when at one of the jobs the cross-wound bobbin has reached its prescribed diameter and must be replaced with a new empty tube. That is, for example in the DE 44 43 818 A1
  • the service units described above can not only eliminate "normal" thread breaks, but also carry out automatic cross-bobbin / empty tube changes.
  • the service units have various facilities. They are equipped, for example, with an auxiliary thread delivery device for providing the auxiliary thread required for rewinding after a cheese / empty tube change, and a thread laying device for fixing the new thread to the empty tube held in the bobbin frame of the winding device between sleeve plates and for creating a so-called thread reserve winding.
  • the service units have, for example, a thread laying device with a pivotally mounted yarn guide plate, which moves the new thread in the region of a sleeve plate of the creel that a sleeve plate arranged on the circumferential thread catching device capture the spun yarn, pull in a driving groove and more or less can fix securely. Subsequently, an initial reserve winding is created by means of the Fadenleitbleches in the region of the sleeve foot of the empty tube.
  • the invention is based on the above-mentioned prior art, the object to provide a service unit, the yarn laying device is modified so that not only a proper setting of the new spun yarn is held on the empty frame held in the bobbin empty machine, but that during the subsequent creation a Fadenreservewicklung is ensured that the Fadenreservewicklung is always stored properly on the sleeve foot of the empty tube.
  • a service unit whose thread laying device is equipped with a second, separately controllable drive for the thread guide and reversing lever has the advantage that the pivotally mounted Faden operations- and lever is temporarily positioned in a so-called Schrägzug too.
  • the Faden operations- and reversing lever clamped between the sleeve plate of the winding device and the front side of an empty spider filament is acted upon with an obliquely directed to the regular yarn direction force component, which ensures that the spun yarn is immediately returned to the empty tube. That is, by the positioned in the Schrägzug ein Faden operations- and lever is reliably avoided that the spun yarn lingers too long in the empty tube / sleeve plate and the thread reserve is thereby accidentally wound next to the empty tube.
  • the second drive is designed as a pneumatic cylinder whose piston rod corresponds during extension with a arranged on the thread guide and reversing lever switching plate.
  • a pneumatic cylinder whose piston rod corresponds during extension with a arranged on the thread guide and reversing lever switching plate.
  • pneumatic cylinders are proven, cost-effective mass-produced components, which are characterized by a long life and high reliability.
  • the Faden arrangements- and reversing lever is also acted upon by a spring element, which ensures that the Faden arrangements- and deflection wire, when the pneumatic cylinder is depressurized, is automatically reset from the Schrägzug too in the winding position, the position of the Thread reserve winding on the empty tube pretends.
  • the retrieved onto the empty tube thread is then guided by the positioned in the winding position Faden operations- and reversing lever that a proper Fadenreservewicklung is created on the sleeve foot of the holder frame rotatably supported Erten empty tube. That is, a thread reserve winding, on the one hand during the winding process and the subsequent transport operations safely in its predetermined position, on the other hand, if necessary, but easily accessible and easily solvable.
  • FIG. 1 One half of a known open-end spinning machine 1 is shown.
  • Such open-end spinning machines 1 have a plurality of in series next to each other, identical work stations 2, which are each equipped with a spinning device 3 and a winding device 4.
  • the spinning devices 3 the sliver 5 presented in sliver cans 6 is spun into filaments 7, which are wound on the winding devices 4 to cheeses 8.
  • the winding devices 4 are each equipped with a creel 9 for rotatably supporting an empty tube 10 or a cheese 8 and a winding drum 11 for driving the cheese.
  • the work stations 2 each have a thread-changing device 18, a working-own suction nozzle 14 as well as a work-station-own piecing element 20. That is, the jobs 2 are equipped so that they can fix thread breaks automatically if necessary.
  • the open-end spinning machine 1 also has a bobbin transport device 12 for disposing of the cheeses 8 finished on the winding devices 4.
  • a service unit 16 On or on the open-end spinning machine 1, movably mounted on a guide rail 13 and a support rail 15, a service unit 16 is arranged. Such service units 16 patrol along the workstations 2 of the open-end spinning machine 1 and engage automatically when a need for action arises at one of the workstations 2. Such a need for action exists, for example, if at one of the workstations 2 a full cross-wound bobbin 8 is exchanged for a new empty tube 10 and the workstation 2 subsequently has to be rewound again.
  • the service unit 16 has for this purpose, as is known, numerous facilities that allow a proper cheeses / Leerhülsencic. Of these numerous facilities are in Fig. 1 only one auxiliary thread supply device 21 with associated delivery tube and the thread laying device 23 are shown. Auxiliary thread supply devices 21 and thread laying device 23 are known per se and for example in the DE 101 39 072 A1 described in relative detail.
  • the thread laying device 23, the in Fig. 2 is shown in a larger scale, is limited rotatably mounted and can be pivoted to pass a thread from the service unit 16 out in the range of a coil in the frame 9 a work 2 rotatably mounted empty tube 10.
  • the thread laying device 23 consists essentially of a support arm 39, which is mounted in an intermediate wall of the service unit 16 with respect to its pivot axis 42 both limited rotation, and axially displaceable.
  • a head element 40 is fixed end, as shown in the Figures 2 and 3 can be seen, connected via a pivot axis 44 to the support arm 39 and can be pivoted about a pneumatic cylinder 45 slightly laterally.
  • a Fadenanlegerkopf 47 is articulated, the various functional elements, such as a yarn brake 35, a Faden Operationss- and lever 34, a thread cutting device 31 and a Fadenumlenkrolle 33 carries.
  • the Fadenanlegerkopf 47 is limited relative to the head member 40 by means of a pneumatic cylinder 48 about the pivot axis 46 rotatably.
  • a pneumatic cylinder 49 is provided, which controls the aforementioned functional elements via a linkage 54.
  • the head member 40 further includes a stopper pin 25 for the Faden Operationss- and lever 34 and a sleeve plate 32, which can be applied to one of the sleeve plate 30 of the coil frame 9, that between the sleeve plate 30 and the end face 27 of the empty tube 10, a gap arises, in the new thread 7 can be inserted and fixed.
  • the Faden Operations- and lever 34 has a switching element 26, which corresponds to the pivoting of the acted upon by the pneumatic cylinder 48 Fadenanlegerkopfes 47 with a arranged on the head element 40 stop pin 25.
  • Fadenanlegerkopf 47 is further a separate drive 19, preferably a pneumatic cylinder, arranged, the piston rod when extending to a on Faden Operationss- and Shift lever 34 arranged shift plate 29 presses while the Faden Operationss- and lever 34 in a so-called Schrägzug too II ( Fig. 4B ) presses.
  • the service unit 16 is ordered to the relevant job 2 and there automatically changes the full cheese 8 against a new empty tube 10. That is, after the ejection of the full cheese 8 from the creel 9 is by appropriate (not shown) handling facilities of the service unit 16 first placed a new empty tube 10 between the tube plate 30 of the creel 9 of the relevant job 2 and then to re-spinning the spinning device 3 of Job 2 by the auxiliary yarn supply device 21 of the service unit 16 an auxiliary thread provided.
  • the thread laying device 23 is at this time in the in Fig. 1 indicated detent position.
  • the delivery tube of the auxiliary thread supply device 21 is pivoted into the upper operating position, being replenished by the auxiliary thread supply device 21 according to auxiliary thread.
  • the pivoting of the delivery tube in the upper operating position of the auxiliary thread is pulled over the guide roller 33 of the thread laying device 23, which is still positioned in its locked position at this time.
  • the thrust piston 41 is driven so that the thread laying device 23 in their, in Fig. 2 shown working position pivots forward.
  • the auxiliary thread is thereby threaded into the arranged on the thread laying device 23 thread cutting device 31 and the yarn brake 35.
  • the suction nozzle 14, which pneumatically fixes the thread beginning of the auxiliary thread pivots downward and passes the auxiliary thread to the Anspinnorgan 20 of the job. 2
  • a corresponding yarn preparation device of Anspinnorgans 20 preferably a known, pneumatically acted preparation tube, the thread end of the auxiliary thread is prepared for the subsequent piecing process and the auxiliary thread for the piecing process held.
  • the now free suction nozzle 14 pivots back into the thread receiving position already described above, in which also the delivery tube pivots on.
  • the delivery tube of the auxiliary thread is in a thread withdrawal device of the service unit 16 inserted, which is formed, for example, as a mechanically working roller supply plant.
  • the auxiliary thread is now separated by a thread cutting device arranged within the auxiliary thread delivery device 21, emerges from the mouth of the delivery tube due to prevailing within the auxiliary thread delivery device 21 and is immediately into the suction nozzle 14 by the negative pressure prevailing in the region of the suction opening of the suction nozzle 14 sucked. That is, the auxiliary thread is now held between the Anspinnorganen 20 of the job 2 and the workstation's own suction nozzle 14 and runs through the thread laying device 23, the thread withdrawal device 56 of the job 2 and a thread withdrawal device of the service unit 16th
  • the thread laying device 23 is then acted upon by the thrust piston gear axially to the pivot axis 42 and positioned with a (not shown) stop element on the housing of the winding device. 4 Subsequently, the head member 40 is pivoted about the pivot axis 44 by a pneumatic cylinder 45 and presses with a head member 40 attached to the sleeve plate plate 32 one of the sleeve plate 30 of the coil frame 9 slightly outward.
  • the auxiliary thread which is then connected via a so-called piecing with the new spun yarn 7, on the in Fig. 1 indicated thread withdrawal device 56 of the job 2 and the approximately synchronously running thread withdrawal device of the service unit 16 withdrawn from the spinning device and disposed of by the suction nozzle 14 of the job 2. This disposal continues until the piecer passes a sensor device (not shown). If the piecing is detected, the actual application of the spun yarn 7 to the empty tube 10 and the winding of the thread reserve 28 takes place on the empty tube 10th
  • the new filament 7 is cut by the thread cutting device 31 just above the empty tube 10 and disposed of the cut thread piece on the suction nozzle 14 immediately.
  • the new spun yarn 7 is fixed by the yarn brake 35, which is positioned in the yarn running direction shortly before the empty tube 10.
  • the thread separation is closed by pivoting back of the head member 40 about the pivot axis 44 of the sleeve plate 30 and the filament 7 between the empty tube 10 and end face 27 of the empty tube 10 securely clamped.
  • the winding drum 11 is started and accelerates the over-frictional resting empty tube 10 to winding speed.
  • the spinning device 3 continuously produces filament 7 from the start, it can both during the fixing of the spun yarn 7 in the gap sleeve plate 30 / empty tube 10, in which the filament 7 comes to a brief halt, as well as when winding the spooling drum 11 at winding speed to a Thread excess come, which can be temporarily stored in a (not shown) storage nozzle of the job 2 for a short time.
  • the winding drum 11 is already accelerated to a predetermined winding speed before the empty tube 10th with the clamped between the empty tube 10 and sleeve plate 30 spun yarn 7 is placed on the winding drum. In this way, the amount of spun yarn 7 to be stored temporarily in the course of re-spinning can be significantly reduced.
  • the thread cutting device 31 and the thread brake 35 are opened by appropriate control of the thrust piston 49 and the pneumatic cylinder 19 in the direction of "piston rod extended” driven.
  • the Faden Resultss- and lever 34 is first spring loaded pivoted in the winding position III and then by the extending piston rod of the pneumatic cylinder 19, which corresponds to a shift plate 29 on the thread guide and lever 34 from the in Fig. 4C shown winding position temporarily displaced III in the oblique position II, as shown in Fig. 4B is shown.
