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-PS 19 16 580.
  • DE-AS 22 55 065 discloses 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 as a transmission element, which is articulated between the guide rail for the pivoting of the thread guide and the actuating rod of the bobbin holding arm and in which the one from the increase in the winding diameter and the periodic reciprocating movement 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 outlay for maintenance, downtime and downtime of the winding devices.
  • the flank angle on the coils cannot be adjusted continuously but only in steps between the intended catches 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 patent claim 1 in such a way that the disadvantages of the known device with regard to the guidance of the obliquely moved push rod are avoided and that the flank angles of the coils are simultaneously and infinitely variable for all winding positions of the winding device can be adjusted.
  • the specified solution also uses a lever 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). While the lever in the known device is firmly articulated at both ends and the sliding block must be displaced by changing the effective geometric lengths of the force and load arm in order to bring about a change in the flank angle of the coils, the subject of the invention is a on a guide rod pivoted intermediate link, which rests between the load arm of the lever and the guide rail for pivoting the thread guide, moved in the longitudinal direction of the lever.
  • the intermediate member can be brought into any position between the possible end positions on the load arm of the lever. This allows any desired flank angle of a spool to be set for all spool positions.
  • Claims 2 to 6 indicate advantageous developments and preferred constructive configurations of the invention, which will be explained in more detail below with reference to the drawing, which merely shows an exemplary embodiment.
  • 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 those for the ing invention essential parts are shown.
  • a winding device for textile threads, tapes, glass fibers, wires or similar linear structures, of which only those for the ing invention essential parts 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 traversing 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 the pin 4 by a reversing thread roller (not shown) and a boat-shaped sliding block which is moved back and forth in the reversing thread groove and is guided in a straight line through the rod 5.
  • the plate 3 could also be firmly connected to the rod 5, while the 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 in the guide rail 9 by a guide roller 6, which is rotatably arranged at its other end, 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 width 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 in a winding device according to the invention 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 two-armed lever 13, the pivot point of which is designated 13.1.
  • a lever arm 13.2 on the force arm side in the sense of this Invention of the arm of the lever 13 defines in which the adjusting force, in particular the adjusting force from the coil lever arm, is introduced.
  • the arm of the lever 13, from which the adjusting forces are transmitted to the guide rail 9, is referred to as the lever arm 13.3 on the load arm side.
  • the adjusting force generated by the respiratory control of the take-up device is additionally introduced into the lever at pivot point 13.1, namely by a second actuating device 14 designed as a rod.
  • This rod carries a feeler element 14.1 at its free end and is at its other end by one Pin 15 rotatably mounted on the machine frame.
  • the lever 13 is rotatably mounted on the rod 14 in its pivot point 13.1.
  • 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 units in the textile machine - sliding blocks 17 are fastened, which have a bearing surface 17.1.
  • the sensing element 14.1 of the actuating device 14 is held non-positively against this bearing surface.
  • the adjustment forces are transmitted indirectly according to Fig. 1, i.e. via a further lever 19, which has an abutment at 19.1 on the machine frame and can be pivoted un.
  • the intermediate links 18 are arranged analogously to the guide stones 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 together with the push rod 16 in a guide fastened to the machine frame 21 stored.
  • Low-load 13.3 on the lever 13 can be changed from a maximum length to a minimum length (shown as an invisible pressure roller).
  • the Abdschrlle is in the 18.1 to the pivot point 13.1 of the lever 13, while cylindrical coil would wound while in allthingLStellungen the Ab - spinning roller 18.1 is wound with tapered edges to the largest possible length of the load arm 13.3 coils
  • the guide rail 9 is constantly under the effect of an e. is nice Energy storage device 22, for example a spring, which energy storage device is arranged on the other side of the lever system with regard to the bearing 7 of the guide rail 9 located locally in between.
  • FIG. 2 differs from the exemplary embodiment of FIG. 1 essentially solely by the constructive design of the transmission system for the adjusting forces of the coil lever arm and breathing control on the guide rail 90 of the traversing device.
  • the two-armed lever 130 is articulated with its lever arm 132 on the power arm side to the actuating device 120 of the coil lever arm.
  • Its fulcrum or support part 131 is designed as a projection 134 with a convex contact surface and is held in contact with the inclined contact surface 171 of the sliding block 170.
  • the pivot point 131 shifts only slightly as a result of the rolling movement of the projection 134 on the contact surface 171.
  • the adjustment force of the breathing control transmitted by the sliding block 170 is introduced into the lever 130 via the projection 134.
  • the intermediate member 180 pivotally mounted on the guide rod 200 is arranged, but in the embodiment according to FIG. 2, however. transmits the forces directly to the guide rail 90 and the guide rail is optionally pivoted about the bearing 70 as the coil diameter increases.
  • the intermediate member 180 can also, as described above, be moved, for example, between the two end positions shown, as a result of which the flank angles of the coil can be continuously adjusted from a minimum biconus angle to an angle of 90 for cylindrical cross-wound bobbins.
  • the constant is advantageously used once it has been set for the selected flank angle
  • Gear ratio between the force arm and the load arm of the lever 130 controls the stroke shortening, which must be carried out with coils with flank angles deviating from cylindrical coils with increasing coil diameter. This happens because the slide rail 90 is pivoted more and more.
  • the slight displacement of the pivot point 131 on the projection 134 of the lever can be compensated for by the shape of the intermediate member 180.
  • the guide rail 90 is not pivoted when the intermediate member 180 has been moved to the position shown in dashed lines and its contact surface is arranged above the pivot point 131 of the lever 130.
  • This position of the intermediate member 180 is provided for cylindrical cross-wound bobbins, while all other positions between this and the other end position result in bobbins with different conical flank angles.
