Definitions

  • the invention relates to a traversing device on winding devices for threads, tapes or the like according to the preamble of patent claim 1.
  • Such a traversing device is known from DE-B 22 55 065. It also shows a device for jointly setting different flank angles on the bobbins for the entire winding device having a plurality of bobbins.
  • a lever is used in DE-B 22 55 065 as a transmission element, which is articulated on the guide rail for pivoting the thread guide and the actuating rod of the bobbin holding arm and in which - from the increase in the winding diameter on the one hand and the periodic back and forth Movement of a common push rod for changing the winding structure on the other hand - resulting adjusting forces for pivoting the guardrail can be initiated.
  • a disadvantage of the known arrangement is that the push rod, through which the adjusting forces from the periodic back-and-forth movement of the respiratory control are introduced into the lever, must constantly perform an oblique movement because the sliding block can only be moved between the inclined surfaces of the catch rail. However, guiding such a movement is structurally difficult.
  • Another disadvantage of the known device is the mechanical wear which necessarily occurs between the catches of the sliding block and the catches of the fixed catch rail and the associated increased effort for maintenance, downtime and downtime of the winding devices. Finally, it is felt to be disadvantageous that the flank angle on the coils cannot be adjusted continuously but only gradually between the provided catches of the catch rail.
  • the guidance of the connecting rod connected to the sliding block is also difficult in this embodiment, since it moves obliquely during its back and forth movement - due to the displacement of the sliding block on the wedge surface of the slide.
  • the flank angle on the coils is also adjusted in stages by adjusting the slide on the bars of the catch rail.
  • the object of the invention is to provide a traversing device on winding devices of the type specified in the preamble of claim 1 in such a way that the disadvantages of the known devices with regard to the guidance of the obliquely moved push rod are avoided, and that for all winding positions of the winding devices the flank angles of the coils simultaneously and can be continuously adjusted.
  • the specified solution also uses a lever arrangement to transmit the adjustment forces from the changes in diameter on the coils and breathing (periodic reciprocating movement of the push rod to influence the coil structure).
  • the lever in the known device is firmly articulated at its end remote from the pivot point and the sliding block has to be displaced by changing the geometric distance between the pivot point and its support surface in order to bring about a change in the flank angle of the coils
  • the subject of the invention is one at a Support rod movably mounted in the direction of the pivoting movement of the lever, which is arranged between the lever and the guide rail and whose distance to the pivot point of the lever is adjustable by the displacement of the guide rod.
  • a major advantage of the present arrangement is that the push rod of the cam control with which the coil assembly be is influenced, is moved back and forth alone to maintain breathing and the adjusting forces are transmitted to the support surface of the lever by a sliding block attached to the push rod.
  • the guide of the push rod in the winding device is therefore very easy to carry out.
  • the intermediate member between the possible end positions on the lever can be brought into any position between its free end and the support of the cam control. This means that any desired flank angle of a spool can be set collectively for all spool positions.
  • FIG. 1 shows a traversing thread guide 1 in a winding device for textile threads, tapes, glass fibers, wires or similar linear structures, of which only the parts essential for the present invention are shown.
  • a winding device for textile threads, tapes, glass fibers, wires or similar linear structures, of which only the parts essential for the present invention are shown.
  • several winding devices are arranged next to one another and, if necessary, one above the other in the associated textile machines, such as spinning, winding, twisting or texturing machines.
  • the thread guide 1 is attached to an angle lever 2, which is pivotally attached to a plate 3.
  • the plate 3 is driven, for example, via a pin 4 by a reversing thread roller (not shown) and a boat-shaped sliding block which is reciprocated in its reversing thread groove and is guided in a straight line by a guide rod 5.
  • the plate 3 could also be firmly connected to the guide rod 5, while the guide rod 5 is moved back and forth in a different, suitable manner by a traversing mechanism such as a cam, eccentric disc, etc.
  • the angle lever 2 is also guided by a roller 6, which is rotatably arranged at its other end, in a guide rail 9, which guide rail can be pivoted about the pin 8 rotatable in the bearing 7.
  • the guide rail 9 preferably has a U-shaped cross section for lateral guidance of the roller 6.
  • the position of the guide rail 9 during the traversing is decisive for the length of the traversing stroke, i.e. the traversing stroke remains constant during the winding cycle if the position of the guide rail 9 also remains unchanged during the entire winding cycle.
  • the position of the guide rail 9 is adjusted on the one hand depending on the growing diameter of the spool 10 via the spool lever arm (not shown) pivoting away from the friction roller and an actuating device 12 connected to it, for example, by the Bowden cable 11.
  • the actuating device 12 acts here to transmit the adjusting force to a one-armed lever 13, which is connected at 13.1 to the breathing lever 14 described later.
  • the adjusting force of the coil lever arm as the coil diameter grows is introduced at pivot point 13.2 at one end of the one-armed lever 13.
  • the part of the one-armed lever 13 between which the sum of the adjusting forces is transmitted to the guide rail 9 is designated 13.3.
  • the adjusting force generated by the breathing control of the winding device is additionally introduced into the one-armed lever 13, namely by the breathing lever 14 of the cam control 14 to 17.
  • This breathing lever 14 has a contact surface 14.1 and is pivoted at its other end on a pivot axis 15 on the machine frame.
  • the one is pivotably mounted on its connecting joint 13.1 on the breathing lever 14.
  • the textile machine has a push rod 16 which is guided parallel to the longitudinal direction of the machine and is driven and is moved back and forth during the bobbin travel according to a predefinable program. On this push rod 16 - according to the division of the winding positions in the textile machine - cams 17 are fastened, which have a support surface 17.1.
  • the bearing surface 14.1 of the breathing lever 14 is pressed against this supporting surface in a force-locking manner.
  • the support member 18 located between the one-armed lever 13 and the transmission lever 19, by its adjustment in the machine longitudinal direction according to the invention for all Winding positions of the desired flank angle
  • Coils 10 is collectively adjustable, is pivotally mounted on a guide rod 20 parallel to the push rod 16 or longitudinal axis of the machine on a pin 20.1. All support members 18 are arranged analogously to the cams 17 fastened on the push rod 16 at intervals, corresponding to the winding position division, on the guide rod 20.
  • the guide rod 20 itself is mounted together with the push rod 16 in a guide 21 fastened to the machine frame.
  • the support member 18 with the push-off roller 18.1 provided at its end is displaced between the one-armed lever 13 and the transmission lever 19, the distance between the connecting joint 13.3 to place the power transmission from a greatest distance to a smallest distance (shown as an invisible pressure roller) is changeable.
  • the pressing roller 18.1 is located above the connecting joint 13.1 of the one-armed lever 13, cylindrical coils are wound, while in all other positions of the pressing roller 18.1 coils with conical flanks are wound up to the greatest possible distance of the pressing roller 18.1 from the connecting joint.
  • the force transmitter is arranged beyond the lever system.
  • Fig. 2 differs from the embodiment of Fig. 1 essentially solely by the design of the transmission system for the adjusting forces of the spool arm and breathing control on the guide rail 90 of the traversing device.
  • the one-armed lever 130 is articulated at its one end in the pivot point 132 to the actuating device 120 of the coil lever arm.
  • Its support surface 131 is designed as a projection 134 with a convex shape and bears against the cam surface 171 of the sliding block 170.
  • the support surface 131 shifts only slightly as a result of the rolling movement of the projection 134 on the cam surface 171.
  • the adjustment force of the breathing control transmitted by the sliding block 170 is introduced into the one-armed lever 130 via the projection 134.
  • the support member 180 which is pivotably mounted on the guide rod 200 is arranged, but which, according to the exemplary embodiment of FIG. 2, transmits the adjusting forces directly to the guide rail 90 and the guardrail may be pivoted about the pivot bearing 70 as the coil diameter increases.
  • the support member 180 can also, as described above, be moved, for example, between the two indicated end positions, as a result of which the flank angle of the coil 10 can be continuously adjusted from a minimum biconus angle to an angle of 90 ° for cylindrical cross-wound bobbins.
  • the constant transmission ratio of the adjusting forces on the one-armed lever 130, that is, once set for the selected flank angle is advantageously used.
  • the slight displacement of the contact line of the support surface 131 of the one-armed lever 130 on the cam surface 171 can be compensated for by the shape of the support member 180.
  • the guide rail 90 is not pivoted when the support member 180 has been moved to the position shown in dashed lines and its contact surface has been eroded over the support line 131 of the one-armed lever 130.
  • This position of the support member 180 is provided for cylindrical cross-wound bobbins, while all other positions between this and the other end position result in bobbins 10 with different conical flank angles.
