Definitions

  • the invention relates to a method and device for quickly restoring the spinning operation after an interruption on reaching a desired bobbin filling, thread length or bobbin size of the cross-wound bobbin holding the spun thread and held in a bobbin frame at a spinning position of an OE spinning machine which has a plurality of spinning positions.
  • a mobile bobbin changing device can be provided with devices for forming the thread reserve.
  • Such a bobbin changing device can be arranged to be mobile on the OE spinning machine.
  • the invention has for its object to contribute to the rapid restoration of the spinning operation after an interruption when reaching a desired bobbin fullness, thread length or bobbin size of the bobbin receiving the spun thread.
  • this object is achieved in that the thread end by means of the piecing unit is automatically wound as a thread reserve on a sleeve end protruding from the cross-wound bobbin, while at the same time the end of an auxiliary thread is also automatically drawn off from a supply bobbin by means of the piecing unit, to the spinning element of the spinning station passed and applied to existing or fed fibers there, that after the formation of the thread reserve, the package is automatically removed from the bobbin frame of the spinning station and replaced by an empty tube, while at the same time the thread, which has since been spun again, is continuously drawn off from the spinning element, below Eliminate the auxiliary thread piece to the tube, passed to the spinning station and continuously wound up to a new package.
  • the mobile piecing unit for piecing when changing the bobbin has a piecing device provided with a supply bobbin and a piecing device which cooperates with the devices for locating and removing the thread end from the surface of the bobbin, the sucked-in thread as a thread reserve on the tube end of the produce cross winding reel-up reserve formation device, the reserve formation device and the piecing device being designed in such a way that they cannot work in an obstructive manner at the same time and can be switched on at the same time.
  • the mobile piecing unit thus receives parts that it normally does not have. It takes on activities that it normally does not do. A special bobbin changing device that can be moved independently of the piecing unit is no longer required.
  • Fig. 1 shows the bobbin 1 with its sleeve 2, on the projecting end on the left side, the thread end 3 is wound into a thread reserve 3 '.
  • the thread end lying laterally across the end face of the package 1 makes it easy to recognize the thread end and to pick it up again.
  • Fig. 2 shows the example of a device 4 for locating and pulling the thread end from the surface of the package 1 as a suction nozzle.
  • the suction nozzle 4 has a suction mouth 4 'directed against the surface of the cheese 1'.
  • the suction nozzle 4 has a guide slot 5 for the thread being sucked in.
  • the guide slot 5 begins at one end of the suction mouth 4 'and extends obliquely over the wall of the suction nozzle 4 towards the package.
  • the arrow 1' marks the direction of rotation of the package 1 during the normal winding process. To suck the thread end, the cheese 1 is rotated against the direction of arrow 1 '.
  • the thread end comes into the suction mouth 4 ', comes under the influence of the air flowing in the direction of arrow 5' and slides into the guide slot 5. If the package 1 is then rotated in the direction of arrow 1 ', the sucked thread end slides in the guide slot 5 along to the left down to the left end of the suction mouth 4 ', after which it slides over the edge of the bobbin as a string and reaches the sleeve 2, where it is wound up as the bobbin 1 as a thread reserve 3'.
  • Fig. 2 shows the device 4 only for example. There are also other ways of sucking in the thread end and guiding it, for example, to the sleeve end by mechanical guide elements so that it can be wound up there.
  • 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.
  • friction rollers can serve as spinning elements in another configuration.
  • the drives 10 and 11 are designed here as whorls, which are driven by tangential belts 10 'and 11'.
  • the air serving in a known manner for fiber transport is sucked out of the spin box 6 via a suction air connection 12.
  • the thread 8 ' is drawn off at a constant speed from the take-off shaft 13 with the aid of a pinch roller 14 resting resiliently on the thread and on the take-off shaft.
  • the thread 8 ' is passed to a back and forth thread guide 16.
  • the thread guide 16 oscillates in the immediate vicinity of the bobbin 1, so that the thread 8 'is deposited on the bobbin 1 rotating in the direction of the arrow 1' in intersecting turns and layers.
  • the cheese 1 is pivotally held by a bobbin frame 18. It lies on the winding drum 17 and is driven by friction.
  • the piecing unit 23 has a chassis 24, the rollers 24 'are supported on the rail 25. Under the travel rail 25 there is a traverse 26 carrying suction air, which supplies the piecing unit 23 with suction air via a suction connection 27 which can be coupled. Busbars 28 supply the piecing unit 23 with electrical energy. At the lower end, the piecing unit 23 is supported by support rollers 29 against support rails 30 arranged on the spin boxes 6 of the individual spinning positions.
  • a device 31 for rotating the cheese 1 is pivotally mounted on the housing of the piecing unit 23.
  • the device 31 consists of a pivotable arm, at the end of which there is a drive roller 31 '.
  • the drive roller 31 ' has a built-in motor and can be driven with the help of it rotating forward and backward.
  • a long frame lifter 32 is also pivotally mounted on the housing of the piecing unit 23. The frame lifter 32 is arranged so that it can grip under a handle 18 'of the coil frame 18 and thereby raise and lower the coil frame 18. With a side movement, he can also open and close the left frame arm.
  • a supply spool 33 is mounted on the housing of the piecing unit 23 and supplies an auxiliary thread 33a for piecing on the occasion of a package change.
  • the auxiliary thread 33a is clamped between a conveyor roller 34 and a pinch roller 35.
  • a feeder 36 is through a branch line 27 'to the suction port 27 connected.
  • the feeder 36 is also pivotally mounted on the housing of the piecing unit 23. It is hollow and therefore able to suck the auxiliary thread 33a on the conveying roller 34 when it assumes the position shown in FIG. 3. With a swiveling movement, he can bring the sucked-in auxiliary thread 33 into the area of a take-off roller 39, which takes over the thread take-off during the piecing.
  • the feeder 36 can, however, still pivot behind the right or rear sleeve receiving plate of the bobbin frame 18, whereby it guides the thread that is sucked in so that the thread is gripped by the sleeve plate and clamped between the sleeve plate and the sleeve, for example.
  • the thread can be held on the take-off roller 39 by applying a pinch roller 40.
  • 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 from an upper position 37 '(FIG. 7), taking the thread with it.
  • the feeder 36 pivots in a plane located far back on the housing of the piecing unit 23. He can therefore not simply pass an auxiliary thread 33a picked up on the conveyor roller 34 to the puller 37.
  • the auxiliary thread 33a is guided to the center for insertion into a thread feeder 42 and into a cutting and untwisting device 41. This is done by means of a guide lever 38 which can pivot from the rear to the center.
  • the cutting and untwisting device 41 has the task of cutting off the inserted thread and preparing the end of the thread for piecing, for example by pneumatic unscrewing.
  • the thread feeder 42 brings the thread end by a pivoting movement of the feeder arm 42 'in the suction area of the draw-off tube 8 of the spinning unit 6.
  • the thread is guided down from the take-off roller 39 of the piecing unit 23 and returned to the normal running position at the spinning position. This is done by a transmitter 43 which is pivotable against the tensile action of a tension spring 44 about the pivot point 43 '.
  • the transmitter 43 carries a small roller 43a, which is arranged axially parallel to the take-off roller 39 when the transmitter 43 assumes its rest position shown in FIG. 3.
  • the thread is pressed laterally from the take-off roller 39 onto the roll 43a of the transfer device 43 and at the same time the winding speed of the package 1 is somewhat increased.
  • the transmitter 43 is pulled against the force of the spring 44 in the direction of the spinning station.
  • the thread loop (FIG. 6) between the spinning station and the piecing unit 23 is used up.
  • the suction nozzle 4 pivots against the cheese 1. After picking up the thread, the suction nozzle 4 pivots back so far that the puller 37 can grasp the sucked thread in front of the suction mouth 4 '(Fig. 7) in order for the normal piecing insert the cutting and untwisting device 41 and into the thread feeder 42.
  • a about the pivot point 45 'pivotable bobbin ejector 45 is able to bring the cheese 1 out of the open bobbin frame 18 on the bobbin conveyor belt 19.
  • a about the pivot point 46 'pivotable sleeve feeder 46 then grips with its gripper 46a, a sleeve 2 from the magazine 21 and presents it to the opened coil frame 18 when pivoting further.
  • the coil frame 18 clamps the sleeve.
  • Fig. 3 shows the spinning station during normal spinning.
  • the piecing unit 23 is parked in front of the spinning station.
  • Fig. 4 shows the piecing unit 23 during the package change.
  • the spinning process was automatically interrupted and the piecing unit 23 requested by reaching the intended thread length, the intended bobbin filling or the intended bobbin diameter at the cross-wound bobbin 1 of the spinning station. This was done in a way known in itself. There is, for example, the possibility of stopping the piecing unit 23 in front of the spinning station in that the spinning station extends a bolt which at the same time also triggers the signal for the automatic piecing unit 23 to act.
  • the frame lifter 32 grips under the left frame arm of the bobbin frame 18 and holds the bobbin 1 in a position raised from the bobbin drum 17, as shown in FIG. 4.
  • the device 31 pivots so far against the package 1 that the drive roller 31 'bears against the surface of the package 1.
  • the cheese 1 is now rotated against the direction of arrow 1', that is against the winding direction.
  • the thread end is picked up by the suction nozzle 4.
  • the drive direction of the cheese 1 is reversed, so that the sucked thread end according to FIGS. 1 and 2 is wound onto the left end of the sleeve 2 to a thread reserve 3 '.
  • the feeder 36 has gripped and sucked the auxiliary thread 33a on the conveyor roller 34. With the thread sucked in, it was then pivoted into the position shown in FIG. 4, 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 had pushed the auxiliary thread 33a towards the center, so that the puller 37 would draw it from the line shown in FIG. 4 with solid lines Position. When swiveling down, the puller 37 had gripped the auxiliary thread 33 and carried it downward as a loop, as shown in FIG. 4. Meanwhile, the conveyor roller 34 had supplied the necessary thread length.
  • the auxiliary thread 33a When pulling the thread loop down, the auxiliary thread 33a has been guided past the feeder 42 and the cutting and clamping device 41. Thereafter, the puller 37 pivoted upward again while the pinch roller 40 was opened somewhat, so that the auxiliary thread 33a was kept under tension by the suction effect of the feeder 36. The auxiliary thread 33a then lay in the clamps of the thread feeder 42 and in the cutting and untwisting device 41, as shown in FIG. 4. The auxiliary thread 33a was cut off on the cutter. Its end was unraveled and turned up. One thread end of the auxiliary thread 33a is thus already prepared for piecing while the bobbin change is not yet completely finished. The other end of the thread is in feeder 36.
  • the thread feeder 42 now pivots in the direction of arrow 60 until it comes to the position shown in FIG. 5, the thread end can be released and pneumatically passed through the draw-off tube 8 to the spinning element 6 '. There the thread end is placed on already existing or fed fibers, whereupon the thread can be withdrawn from the spinning box, because now the new thread formation has started, especially since the feed drive 9 has also been started.
  • FIG. 5 shows the piecing unit 23 in a position in which the sleeve 2 is being fed to the coil frame 18.
  • the feeder 42 has been pivoted against the draw-off tube of the spin box 6 and had brought the thread end of the auxiliary thread 33a into the suction area of the draw-off tube 8.
  • the take-off roller 39 had conveyed the auxiliary thread 33a back out of the feeder 36 in the direction of the spin box 6.
  • the piecing time has just been exceeded.
  • the thread end has new fibers fed in connected and the take-off roller 39 now pulls the auxiliary thread 33a and the thread 8 ⁇ spun onto it from the spin box 6 at a constant speed.
  • the thread 8 ⁇ is sucked off by the feeder 36.
  • the frame lifter 32 had opened the bobbin frame 18 and the ejector 45 was pivoted into the position shown in broken lines in FIG. 5 in order to convey the bobbin 1 from the bobbin frame 18 onto the bobbin conveyor belt 19.
  • the sleeve feeder 46 had gripped the sleeve 2 in the magazine 21 and carried it into the area of the coil frame 18.
  • the frame lifter 32 had already lowered the spool frame 18 so far that it is in the vicinity of the spool drum 17. Subsequently, the frame lifter 32 had closed the coil frame 18, which was opened to receive the sleeve 2, in order to clamp the sleeve 2. Now the sleeve feeder 46 can pivot back into its starting position shown in FIG. 3.
  • Fig. 6 shows the position of the piecing unit 23 when applying the thread 8 ⁇ to the sleeve 2.
  • the frame lifter 32 holds the bobbin frame 18 raised so far that the sleeve 2 does not yet touch the winding drum 17.
  • the drive roller 31 ' drives the coil 2nd in the direction of arrow 1 ', that is, in the winding direction.
  • the feeder 36 which sucks the continuously spun thread 8 ⁇ , swings past the rear sleeve plate of the bobbin frame 18. As a result, the trailing thread 8 ⁇ comes into a position in which it can be gripped by gripping slits known per se on the sleeve plate.
  • the thread 8 ⁇ After the thread 8 ⁇ has been detected and begins to wind up on the sleeve 2, it is separated by a cutting device, not shown here, attached to the mouth of the feeder 36. The separated end, on which the auxiliary thread piece also hangs, is suctioned off.
  • the feeder 36 can be provided at its end with a contour which first guides the thread to the edge of the sleeve so that an initial reserve can form there. Then the thread 8 ⁇ is pressed down by the take-off roller 39 and delivered to the roll 43a of the transfer device 43. The thread loop is now used up by increased winding speed and as soon as this has happened, the frame lifter 32 releases the bobbin frame 18.
