Definitions

  • the present invention relates to a method for piecing a thread in a spinning rotor of an open-end spinning device, in which the fibers are fed into the spinning rotor after the thread has been returned to the spinning rotor, and to an apparatus for carrying out the method.
  • This object is achieved in that after the return of the thread in the spinning rotor, an increased amount of fiber is briefly fed into the spinning rotor and then the fiber delivery is reduced again to the normal delivery amount. In this way it is achieved that the thread end does not have to burst open a fiber ring already present in the spinning rotor, but that the fiber ring forms over the thread end. Since the latter continuously transmits the rotation it has been given to the fiber ring that is being formed, the fiber ring is always open at the attachment point, so that the problem of having to burst open the fiber ring does not even occur. Since an increased amount of fibers is fed into the spinning rotor for a short time, an amount of fibers is also made available at the time of the piecing, which ensures that the attachment point arising in the thread has a relatively high strength.
  • the temporarily increased fiber feed is chosen so that the unavoidable jump in the thread thickness formed by the end of the back-fed thread end has the smallest possible deviations from the normal thread thickness.
  • the increased amount of fibers is expediently generated by storing fibers when the spinning process is set between a delivery device and a disintegration device, which fibers are suddenly released during spinning, while at the same time the delivery of fibers starts in the normal scope of delivery.
  • the abruptly released fiber mass corresponds to 30% to 50% of the fiber mass that is present in a fiber ring during the normal spinning process. In this way, the thick point in the area of the thread end is kept within acceptable limits, without a too weak thin point subsequently occurring at the same time. It has proven to be particularly favorable if the thread returned to the spinning rotor is deposited on 20% to 40% of the inner circumference of the spinning rotor.
  • a delivery device that can be brought up to an increased delivery speed for a short time can be provided for carrying out the method.
  • a drive is assigned to the delivery device according to the invention, by means of which it can be driven briefly at an increased delivery speed during commissioning and then at a normal delivery speed.
  • a fiber storage device is arranged between the delivery device and the opening device for carrying out the method according to the invention, which briefly absorbs fibers when the spinning process is stopped, which fibers are suddenly released again during piecing.
  • the fiber storage provides the increased amount of fibers required for piecing.
  • the arrangement of the fiber storage after the delivery device ensures on the one hand that the amount of fiber actually stored can be fed suddenly into the spinning rotor, while its arrangement in front of the opening roller ensures that the fibers are separated in the usual way and do not get into the spinning rotor as uncontrolled chunks.
  • the fiber storage is arranged in the area of the fiber beard in a continuation of a housing wall surrounding the opening roller and can be released by a movable fiber insertion.
  • the fiber insertion is a part of the feed trough extending in the circumferential direction of the opening roller, the end of which in the transport direction is assigned a pivot axis for the feed trough.
  • the pivot axis is advantageously designed as a slide stop for the feed trough.
  • the feed trough When the feed is stopped, the feed trough is pressed so far in the direction of the slide stop that the feed trough bears against the slide stop and can only evade the further pressure by a pivoting movement, as a result of which a gusset forming the fiber storage is formed between the opening roller and the feed trough.
  • the feed trough on the side of the clamping point facing away from the opening roller has a stop surface with which a clamping element cooperates during the first part of the pivoting movement of the feed trough, while during the second part of the pivoting movement it is located at the clamping point on the feed trough supports and stands out from the stop surface.
  • the fiber feed is released as a function of the recovered thread tension of the thread returned to the spinning rotor, which is why, according to the invention, the thread store is connected in terms of control to a thread monitor monitoring the thread.
  • U represents the circumference of the collecting trough of a spinning rotor 3 (FIG. 4), in which a fiber ring R is formed by starters, before a thread end E is returned to the spinning rotor 3 for spinning, which is then based on the fiber ring already present as a result of the fiber pre-feeding R drops.
  • the rotation of the spinning rotor 3 gives the thread end E a rotation (FIG. 1). If the centrifugal force is low, the thread end E only rolls on the fiber ring R without involving it, so that the success rate for piecing is low, even if the thread take-off starts somewhat delayed.
  • fibers F are fed into the spinning rotor 3 in a conventional manner and are deposited on the thread end E and on the fibers of the fiber ring R.
  • the fibers F which reach the spinning rotor after the thread is returned have a thickness d.
  • the returned Yarn length 30% of the rotor circumference, so 30% fibers of fiber thickness D are fed onto the yarn end until this yarn length is continuously withdrawn.
  • the thickness d at the end of the returned thread end E serves only to connect the returned thread end E with the newly formed thread G, so that despite the optically present thread thickness, a weak point of only 30% of the fibers in the thread carrying it G arises.
  • the part R1 of the fiber ring R which is connected to the returned thread end E and the part R2 of the fiber ring R which is connected to the newly formed thread G are shown offset from one another in FIG.
  • FIG. 2 shows an attachment point as it arises when no fibers are delivered to the spinning rotor 3 before the yarn end E is returned.
  • the attachment point is then optically weaker, but there is no difference here from the attachment point shown in FIG. 1 with regard to the strength d of the newly formed thread which serves for the connection.
  • the fibers F of the fiber ring R formed by the return of the thread end E in the spinning rotor do not contribute anything to the strength of the attachment point in the thread, since the fiber ring R has to be blown open anyway, an increase in strength can only be achieved by making the thread end E as wide as possible is placed on the circumference U of the spinning rotor. However, this is only possible to a limited extent due to the risk of twisting the thread end E and the resulting short dwell time in the spinning rotor 3. In practice, the returned thread end E usually takes up about 30% of the circumference U of the spinning rotor.
  • the desired thread size d A - also depending on the fiber material to be spun - and the length L of the portion of the thread end E which is deposited in the spinning rotor 3 are determined, which then gives the abruptly released amount of fibers M. It has proven to be advantageous if the abruptly released amount of fibers M corresponds to 30% to 50% of the amount of fibers that are present in a fiber ring R during the normal spinning process. If at the same time the thread end E deposits over 20% to 40% of the circumference U of the spinning rotor, the thickness d A is approximately 70% of the normal thread thickness D (on the basis of average values of the above numbers), so that a considerable increase in the strength of the attachment point previous thread piecing can be determined. The success rate in threading thus increases considerably, so that threading is now also possible under conditions such. B. higher speed of the spinning station can be made, where a preparation was previously not possible.
  • the manner in which the increased amount of fibers M is provided in the spinning rotor 3 at the time of piecing is irrelevant to the invention.
  • a first exemplary embodiment is explained below with reference to FIGS. 4 to 6.
  • the inside of the spinning rotor 3 is fed in a conventional manner with the aid of a delivery device 1 and a disintegration roller 2 to a fiber sliver 4 which is dissolved in individual fibers 40, where the individual fibers 40 enter the collecting trough and form a fiber ring R.
  • the fiber ring R is integrated in a known manner into a thread end E of a thread G, which is drawn off through a thread draw-off tube 30 by means of a pair of thread draw-off rollers (not shown) and wound up in the usual way on a spool (not shown).
  • the thread G is monitored on its way to the bobbin by a thread monitor 31.
  • the negative pressure required for spinning in the spinning rotor 3 is generated in a known and therefore not shown manner.
  • the delivery device 1 has a driven delivery roller 10 and a feed trough 11 which resiliently supports it.
  • the opening roller 2 is arranged in a housing 20, which also carries the feed trough 11, while the delivery roller 10 is mounted independently of the housing 20.
  • a clamping lever 5 which works with its clamping end 50 in the sliver transport direction in front of the clamping area 12 of the delivery device 1 with the feed trough 11 and here a clamping point 15 for the sliver 4 can form.
  • the clamping lever 5 has a sliver guide funnel 51, so that the sliver 4 can pass between the feed trough 11 and the clamping end 50 of the clamping lever 5 to the delivery roller 10.
  • the drive end 52 of the two-armed clamping lever 5 bears against the plunger 54 of an electromagnet 55 by the action of a compression spring 53.
  • the sliver guide funnel 51 protrudes in the sliver transport direction beyond the clamping lever 5, but ends before the clamping end 50 of the clamping lever 5.
  • the clamping lever 5 is further arranged and movable in relation to the feed trough 11 in such a way that during the first part of its pivoting movement, the sliver guide funnel 51 contacts a stop surface 110 of the feed trough 11 is supported without the clamping end 50 having a clamping effect on the fiber sliver 4, but that with the further pivoting movement of the clamping lever 5 the clamping end 50 is supported on the feed trough 11, the sliver guide funnel 51 lifting off again from the feed trough 11.
  • the housing 20 is lined with a thin film 21 which has a feed opening 210 in the region of the delivery device 1 and a discharge opening 211 in the region of a fiber feed channel 22 leading into the spinning rotor 3.
  • the feed trough 11 is supported on the outside of this film 21, so that it always remains in contact with this film 21 during its movements as a result of fluctuations in the sliver 4 being fed.
  • the D E-0 S 2 448 584 shows further possibilities for radial support of a sliding trough.
  • a slide stop 23 is arranged in the immediate vicinity of the film 21 on the side of the feed trough 11 facing away from the delivery roller 10, which prevents the feed trough 11 from sliding beyond the usual frame. If a pressure is exerted on the feed trough 11 in front of the clamping area 12 in the sliver transport direction, then when the feed trough 11 has reached the sliding stop 23, this pressure is converted into a pivoting movement of the feed trough 11.
  • the sensor 310 of the thread monitor 31 thereby released is pivoted by a prestressed compression spring 311 and closes a contact 312, whereby the electromagnet 55 is excited and the clamping lever 5 is pivoted with the aid of the plunger 54.
  • the clamping lever 5 rests against the stop surface 110 and thereby shifts the feed trough 11 so far that it comes into contact with the sliding stop 23.
  • the feed trough 11 is thus pivoted with the aid of its sliver guide funnel 51 without the clamping end 50 of the clamping lever 5 already jamming the sliver 4 (FIG. 5).
  • the clamping lever 5 continues its pivoting movement.
  • the pivoting movements of both the feed trough 11 and the clamping lever 5 now bring the clamping end 50 of the clamping lever 5 at the clamping point 15 into clamping contact with the sliver 4 and the feed trough 11, while the feed trough 11 and the sliver guide funnel 51 move away from one another (FIG. 6 ).
  • the sliver feed to the opening roller 2 is set by clamping the sliver 4, while the fiber storage 6 is further increased.
  • a thread end E is now inserted into the thread take-off tube 30, which is sucked into the spinning rotor 3 due to the negative pressure prevailing in the spinning rotor 3 and which is placed in the collecting channel of the spinning rotor 3 due to the centrifugal force generated by the rotating spinning rotor 3.
  • the thread monitor 31, around the sensor 310 of which the returned thread end E is guided signals the renewed presence of the normal spinning voltage, as a result of which the electromagnet 55 is de-energized.
  • the plunger 54 now releases the clamping lever 5, the clamping end 52 of which completely releases the fiber sliver 4 by the action of the compression spring 53 and immediately thereafter the feed trough 11 with the fiber sliver guide funnel 51.
  • fibers F are thus stored between the delivery device 1 and the opening roller 2 when the spinning process is set, which fibers are suddenly released during piecing, while normal fiber delivery begins at the same time.
  • a suction line can open as the thread store 6 between the delivery device 1 and the opening roller 2, which can have a screen a short distance from its end facing the sliver 4 and which can be effective or ineffective depending on a response of the thread guard 31 .
  • a thread break occurs, fibers are sucked in, which are released again when spinning on (e.g. by reversing the air flow), whereby a timer can ensure that the suction or blown air is only as long as is absolutely necessary. is effective.
  • the fiber storage 6 is arranged in the region of the fiber beard in continuation of the wall of the housing 20 surrounding the opening roller 2 and can be released by a movable fiber insertion.
  • the fiber insertion is formed by a pivotable feed trough 11.
  • FIG. 7 shows an embodiment in which a feed trough 13 is provided which is pivotally mounted on a pivot axis 14, which in turn is arranged at the point where the sliding stop 23 is arranged according to FIGS. 4 to 6.
  • a fiber storage 6 is formed between the surface of the feed trough 13 facing the opening trough 13 and the opening roll 2 itself when the pivoting movement of the feed trough 13 exceeds the usual extent.
  • a single control element serves both to control the fiber storage 6 and to control the clamping of the sliver 4.
  • a clamping member 7 is provided, for example, which cooperates with a stop 130 provided on the feed trough 13.
  • the clamping member 7 is formed by the plunger of an electromagnet 70, which is controlled as a function of the response of the thread monitor 31 (FIG. 4).
  • the clamping lever 8 provided for clamping the sliver 4 can be controlled independently of the clamping member 7 and with a delay that can be preset by interposing a suitable timing element (not shown).
  • controllable fiber storage 6 - z. B. by a pivotable feed trough 11 or 13 - and a delivery roller 10 which can be stopped with the aid of a clutch, so that here too the fiber storage and the stopping and switching on of the fiber delivery can be carried out independently of one another and thus in an adjustable manner.
  • an opening roller 2 is provided as the opening device and the delivery device consists of a delivery roller 10 and a feed trough 11 or 13. Rather, the delivery device can also consist of two rollers. It is also possible to design the delivery device 1 as a pair of input rollers and the opening device as a pair of output rollers of a drafting system, in which case, of course, the fiber storage device must be designed and adapted accordingly, e.g. B. in the form of an intermediate pneumatic fiber storage. This fiber storage can also work combined pneumatic-mechanical, by z. B. a panel covers or releases a pneumatic and switchable fiber storage.
  • the fiber storage device 6 and the delivery device can always be controlled as a function of the thread monitor 31. But it is also conceivable to use these elements - possibly only additionally - manually or from another control point, e.g. B. the main switch of the machine to control.
  • a clutch 9 is assigned to the delivery roller 10.
  • the clutch 9 has on the drive roller 100 of the delivery roller 10 two freely rotatable drive wheels 90 and 91, with which a driving wheel 92 connected to the drive shaft 100 in a rotationally fixed manner can alternately be brought into engagement.
  • the driving wheel 92 has a circumferential groove 920 into which an adjusting lever 93 engages with its adjusting element 930.
  • the actuating lever 93 is connected to the armature 940 of an electromagnet 94, which is electrically connected to the thread monitor 31 via a control element 95.
  • the drive wheels 90 and 91 are connected via chains 900 and 910 to drive wheels 901 and 911, which sit on a common shaft 96, which in turn are driven by a motor 98 via drive wheels 97 and 970, which are connected to one another via a chain 971, is driven.
  • the clutch 99 is disengaged via the control element 95, so that the delivery roller 10 is stopped.
  • the clutch 99 is again engaged, but at the same time the driving wheel 92 is brought into engagement with the drive wheel 91, so that the delivery roller 10 from the motor 98 via the drive connection 970, 971, 97, 96, 911, 910, 91, 100 is driven at an increased speed, as a result of which individual fibers F increasingly enter the spinning rotor 3.
  • the fiber delivery quantity is normalized again by the drive connection 98, 970, 971, 97, 96, 901, 900, 90, 100, 10 being established by switching the driving wheel 92 from the control element 95 (time element).
  • the delivery device 1 can thus be driven briefly at an increased delivery speed and then at a normal delivery speed, so that even with such a device, the increased amount of fibers M (FIG. 3) can be fed onto the returned thread end E in such a way that it is in the area the attachment point of the thread is available.
