Definitions

  • the invention relates to a method for changing bobbins on a spinning bobbin winder, in which the delivered thread is wound into a bobbin by means of a traversing thread guide moving in a bobbin area and after the replacement of a full bobbin with an empty tube in a clamping and cutting zone to the side of the Sleeve is clamped and cut off.
  • the invention further relates to an apparatus for performing the method.
  • a disadvantage of this method is that it is not suitable for high winding speeds and can only be used if all the bobbins of the machine are changed at the same time.
  • the thread continuously supplied by the device is cut through before the bobbin change above the take-off rollers and introduced into a swivel nozzle, by pivoting the thread after replacing the full bobbin with an empty tube and with the bobbin holder not yet fully closed Gap between the sleeve and the centering head of the coil holder reaches (DE-OS 2.312.609).
  • the thread is clamped when the bobbin holder is closed and separated by a pair of scissors attached to the mouth of the swivel nozzle.
  • the thread is kept away from the area of the traversing thread guide by a guide wire. After completion of the thread reserve next to the actual bobbin winding, the thread is pressed down by the guide wire, so that it can be gripped by the traversing thread guide and laid according to the bobbin structure.
  • This handling of the thread is also not suitable for high machine speeds at which there is in particular the risk that the thread will not be caught by the traversing thread guide.
  • the object of the present invention is to avoid the disadvantages of the known proposals and to provide a method for guiding and separating a thread and a device therefor, which make it possible to carry out the bobbin change without problems even at high bobbin speeds.
  • the object is achieved in that the traversing thread guide leads the thread from the winding area into the clamping and cutting zone and then back into the winding area.
  • the thread In order to prevent thread strikes from the bobbin, the thread is deflected perpendicularly to the bobbin axis when it is transferred to the clamping and cutting zone.
  • the traversing thread guide expediently brings the thread in the clamping and cutting zone in front of the mouth of a suction pipe, through which the thread continuously supplied by the spinning device can be sucked off.
  • the winding of a thread reserve without additional aids is made possible in that the traversing thread guide is moved back and forth to form a thread reserve winding next to the winding area.
  • the thread is first cut and then clamped after the bobbin is replaced with an empty tube, the clamping advantageously being maintained until the thread reserve is wound up.
  • the device for performing the method is characterized in that the traversing thread guide is releasably attached to the thread guide rod and a displacement means is assigned to it, which moves it with the thread guided in it on the thread guide rod to the cutting and clamping device.
  • a particularly light and fast Decoupling and displacement of the traversing thread guide is made possible in that the traversing thread guide is held in the spinning position by a permanent magnet arranged on the thread guide rod.
  • the traversing thread guide is reset to form the thread reserve on the sleeve in a simple manner by means of a compression spring.
  • the displacement means is arranged on a threaded spindle. Their rotation in one direction or the other is ensured by a reversible motor.
  • the cutting and clamping device is assigned to a spool plate in a space-saving arrangement and forms a structural unit with the latter.
  • the cutting and clamping device is further optimized in that it contains a bolt which is displaceable transversely to the thread running direction in a bore cut through an annular groove and is provided with a groove-defining cutting edge and clamping edge which are arranged one behind the other in the thread running direction and with one through the cut of the hole formed edge cooperate as a counter element. This ensures a quick and defined cut as well as a secure clamping of the thread.
  • the cutting edge and the clamping edge are expediently deliverable to the counter element one after the other.
  • the suction of the thread enables a suction tube which is pivotably mounted in the radial plane of the ring groove and which also inserts the thread into the cutting and clamping device.
  • a thread deflecting fork pivotally mounted in the end region of the bobbin adjacent to the cutting and clamping device prevents thread windings from falling off the bobbin when the traversing thread guide is pushed out with the thread from the winding region.
  • FIG. 1 shows the parts of a winding unit on a spinning winder, for example an open-end spinning machine, which are essential for the explanation of the invention.
  • the thread continuously supplied by the spinning device is wound up by means of a traversing thread guide 1 on a bobbin tube 2 in a cross winding to form a bobbin 21.
  • the spool sleeve 2 is held on both sides in a spool holder (not shown), on the holding arms of which spool plates 22 are rotatably mounted, each of which engages with a centering shoulder in the sleeve ends.
  • the coil sleeve 2 or coil 21 is driven by a drive drum 3 against which it is pressed.
  • the traversing thread guide 1 is arranged on a thread guide rod 11 which is moved back and forth parallel to the sleeve axis in a known and therefore not shown manner, as indicated by the double arrow.
  • the traversing thread guide 1 is displaced on the thread guide rod 11 stored bar, but fixed in position during the formation of the bobbin by a permanent magnet 12 attached to the thread guide rod 11. In the fixed position, the traversing thread guide 1 moves in a winding area which is defined by the width of the bobbin 21.
  • the traversing thread guide 1 is assigned a displacement means 4 which is mounted on a threaded spindle 41.
  • the threaded spindle 41 can be driven by a reversible motor 42.
  • the traversing thread guide 1 can be moved on the thread guide rod 11 in the direction of a sleeve end and beyond this into an end position 1 ⁇ . Tilting of the traversing thread guide 1 about the axis of the thread guide rod 11 is prevented by a guide rod 13 on which the traversing thread guide 1 slides.
  • the end position 1 ⁇ is limited by a fixed stop 43 and a compression spring 44, which is held on the guide rod 13 and attached to the stop 43.
  • the traversing thread guide 1 is located in an area in which the thread continuously supplied by the spinning device is clamped and cut off when the bobbin is changed.
  • the bolt 51 is provided with a groove 52, which is arranged inclined with respect to the annular groove 61 in the structural unit 6, and is displaceable in the bore transverse to the thread running direction.
  • the groove 52 and the annular groove 61 lie in the same plane of rotation.
  • the bolt 51 protrudes in the radial direction with its groove 52 beyond the base of the annular groove 61, so that the tapering thread can be placed in the groove 52.
  • the groove 52 is delimited by a cutting edge 53 and a clamping edge 54, which are arranged one behind the other in the thread running direction.
  • the bolt 51 can be displaced from its initial position shown in FIG. 3 transversely to the annular groove 61 and the thread running direction in the direction of the bobbin 21 such that the cutting edge 53 and the clamping edge 54 of the groove 52 are in functional contact with the exposed edge 71 of the bore, which acts as a counter element 7 come.
  • the displacement of the bolt 51 is effected by a push rod 62, the wedge-shaped end of which engages on an extension 55 of the bolt 51 which projects on the end face of the component 6.
  • a flattened portion 56 on the extension 55 secures the bolt 51 against rotation (FIG. 4).
  • the push rod 62 is arranged at one end of a two-armed lever 63 which can be pivoted about an axis 65 by means of a double-acting lifting magnet 64.
  • the other free end of the lever 63 carries a roller 66.
  • the return of the bolt 52 to the starting position is carried out by a compression spring 72.
  • a thread deflection fork 8 and a suction pipe 9 are also arranged (FIGS. 1 and 2).
  • the thread deflecting fork 8 can be pivoted about a pivot axis lying near the end face of the spool 21 and perpendicular to the sleeve axis from a rest position below the thread running onto the spool 21 into the thread path.
  • the suction pipe 9 can be pivoted about an axis 91 arranged parallel to the sleeve axis from an essentially horizontal thread take-up position 9 ⁇ below the annular groove 61 to a position behind the annular groove 61.
  • the device works as follows:
  • the traversing thread guide 1 is coupled to the permanent magnet 12 and is moved back and forth in the bobbin formation area by the thread guide rod 11.
  • the bobbin 21 is raised to such an extent that it loses contact with the drive drum 3 and the reversible motor 42 activated, which sets the threaded spindle 41 in rotation. Characterized that by a ramp 45 (Fig.
  • the thread guide fork 8 In order to prevent thread strikes from the bobbin 21 when the traversing thread guide 1 is moved beyond the end of the bobbin, the thread guide fork 8 is pivoted into the thread path before or simultaneously with the start of the displacement. The thread lies in the fork 8 and is thus secured against slipping off the bobbin 21.
  • the traversing thread guide 1 In the end position 1 ⁇ is the traversing thread guide 1 with the thread close to the mouth of the suction pipe 9, which has been pivoted into the position 9 ⁇ .
  • the thread continuously supplied by the spinning device when the bobbin 21 is at a standstill is sucked into the suction tube 9 in the form of a loop and is cut by a not shown device, which is suitably arranged in the intake manifold 9, separated from the coil 21.
  • the coil 21 is now exchanged for an empty bobbin tube and this is brought into contact with the drive drum 3.
  • the suction tube 9 is pivoted back with the thread continuously sucked out of the suction position 9 'into the starting position (FIG. 2).
  • the bolt 51 is moved by means of the push rod 62 in the bore 7 and the thread is cut by the cutting edge 53 abutting against the edge 71 of the bore and clamped by the clamping edge 54.
  • the position of the cutting and clamping device 5 is queried by an initiator (not shown) and the actuation of the push rod 62 after one of the peripheral speed of the component 6 pending time triggered by a timer (not shown).
  • the bolt 51 is prevented from moving back into the rest position by a lock in the form of a slide 58 loaded by a spring 57, so that the thread remains clamped (FIG. 5).
  • the spring 57 presses the slide 58 radially outwards, wherein it engages in a groove 59 in the extension 55 of the bolt 51 and protrudes from the component 6.
  • the motor 42 driving the threaded spindle 41 is reversed so that the displacement means 4 moves back against the direction of the arrow P.
  • the compression spring 44 also presses the traversing thread guide 1 in this direction, which thus returns the thread into the winding area, but initially into the radial plane of the thread reserve formation on the bobbin tube 2.
  • the thread reserve is expediently formed in such a way that a longitudinal piece of the thread held clamped is overcome by the reserve winding outside the winding area.
  • the motor 42 driving the threaded spindle 41 is reversed accordingly.
  • the lifting magnet 64 pivots the lever 63 about the axis 65 into the position shown in FIG. 4, in which the roller 66 pushes the slide 58 back into its rest position against the force of the spring 57.
  • the clamping of the thread in component 6 is thus released and the thread guide fork 8 is pivoted back into its rest position.
  • the displacement means 4 is pivoted away from the traversing thread guide 1 into the rest position. The pivoting is expedient when the permanent magnet 12 fastened on the thread guide rod 11 approaches the traversing thread guide 1.
  • the traversing thread guide supported by the restoring force of the compression spring 44, couples to the permanent magnet 12 and the bobbin formation begins.
