Definitions

  • the invention relates to a winding machine for man-made fibers. It is used in particular for winding freshly spun and / or drawn multifilament threads in spinning machines.
  • the winding machine has a traversing device and a winding spindle.
  • the traversing device and the winding spindle are mounted such that they can move relative to one another, e.g. the winding spindle is fixed in a frame and the traversing device is mounted in a movable carriage.
  • Such a winding machine is shown in DE-A-2039772 & FR-A-21 04203, in which the traversing mechanism is mounted in a structural unit consisting of a slide and a cantilever arm attached to it.
  • the carriage is essentially vertical in a straight guide and is guided in such a way that the traversing device can avoid the growing diameter of the bobbin formed on the bobbin spindle.
  • the weight of the unit consisting of slide and support arm is fully or partially compensated for by a force transducer which, in the known winding machine, is designed as a pneumatic cylinder-piston unit.
  • the solution according to the invention according to the characterizing features of claim 1 is characterized in that the force transmitter does not act directly on the carriage, but rather by means of a one-armed or two-armed lever articulated in the frame of the winding machine in the central region of the structural unit consisting of carriage and support arm, preferably in Longitudinal focus of this unit. This prevents the support arm and slide from exerting an impermissible bending moment on the guides and even being subjected to an impermissible bending moment.
  • the lever transmission ratio can be selected so that, despite a large range of movement of the slide, the support arm and the oscillation, i.e. Despite the production of coils with a very large diameter, the length of movement of the force transducer can be chosen to be smaller in the ratio of the lever transmission ratio, which is favorable for friction, wear and space utilization.
  • the force transmitter preferably engages between the swivel point and the longitudinal center of the swivel lever, while the end of the swivel lever rests on the support arm.
  • the force transmitter engages at one end, while the other end rests on the support arm.
  • the lever is designed with two arms and is bent at its pivot point, so that despite the limited length of the frame of the winding machine, a sufficient length of the lever arm is provided for the force application of the force transmitter.
  • the force transmitter used in the context of this invention is preferably a hydraulic or pneumatic cylinder-piston unit. This cylinder-piston unit is applied to a constant or variable pressure in the course of the winding cycle. As a result, part of the weight of the assembly consisting of slide, support arm, traversing, etc. is absorbed. It can thus be achieved that a drive roller, which is also mounted in the support arm, bears against the bobbins to be formed on the bobbin spindle with only a certain, predetermined pressure that may be variable in the course of the winding cycle.
  • the guide used within the scope of this invention is a straight guide, e.g. in the form of a cylinder-roller guide, which is fixed in the frame and on which the slide slides.
  • a design with a particularly high stability of the assembly consisting of the support arm and the slide is achieved in that the assembly is guided in a straight line by two guides which are arranged at the ends of a diagonal of the slide. This gives the guides their greatest possible distance.
  • the point of engagement of the lever with respect to the support arm has a degree of freedom in the longitudinal direction.
  • the free end and the support arm can lie on one another in a plain bearing.
  • the support arm and the lever are connected by an intermediate lever which is articulated on the support arm on the one hand and on the lever on the other hand.
  • An alternative embodiment provides that the point of application of the lever is articulated to the support arm and that the lever itself is free with respect to its frame degree of storage is stored.
  • the swivel joint of the lever can be mounted in a slide bearing.
  • a particularly simple embodiment results from the fact that the swivel joint of the lever is in turn attached to the end of an articulated lever which is articulated in the frame.
  • the force transmitter has a degree of freedom transverse to its direction of force relative to the lever.
  • the power transmitter is pivotally mounted or the power transmitter and the lever are connected to one another by a hinged intermediate lever.
  • the winding spindle 2 is mounted in a stationary and freely rotatable manner in the fixed frame 1.
  • Sleeves 3 are attached to the winding spindle.
  • a coil 4 is formed on each sleeve 3.
  • the coils with the winding spindle are driven by the drive roller 5 (see FIG. 3).
  • Changings 6 are used to move the threads back and forth.
  • Each oscillation 6 consists of a thread guide 7, which is driven in a straight guide 8 by a reversing thread shaft 9, and a grooved roller 10 with grooves embedded therein (cf. FIG. 3).
  • any other traversing can be used, such as a so-called "wing traversing”.
  • the drive roller and the traversing mechanism are mounted in a slide 11 and a support arm 12 attached thereto, the support arm 12 being attached to the slide 11 in a cantilever manner. 1
  • the carriage 11 is movable in two straight guides 13 in the vertical direction. This ensures that the traversing and the drive roller can avoid the growing spool diameter.
  • a force transmitter 14 is provided, in the illustrated case a cylinder-piston unit, as also described by the prior art is known.
  • the piston rod 15 engages via an intermediate lever 16 on a lever 17 which is mounted on one side on the frame 1 in the pivot point 18 and engages with its free end 19 on a slide bearing 20 of the support arm 12.
  • the distance between the pivot point and the point 21 of the force application of the force transmitter 14 on the one hand and the end 19 of the support arm on the other hand is selected such that the slide or support arm with the given stroke length of the force transmitter has the stroke sufficient for the desired maximum coil diameter, which also allows the drive roller to be lifted off the spool surfaces.
  • the slide bearing 20 is attached approximately in the longitudinal center of the support arm and approximately in the longitudinal center of gravity of the entire structural unit comprising the slide 11 and the support arm 12. It is not necessary for this longitudinal center of gravity to be adhered to precisely, since it can be assumed that the guides 13 must be able to absorb a certain moment anyway. However, this design prevents the support arm from exerting an impermissibly high bending moment on the slide 11 and the guides 13.
  • the slide bearing 20 serves to ensure the degree of freedom in the longitudinal direction of the support arm 12 required for the lever end 19 when the lever is pivoted about pivot bearing 18.
  • FIG 4 shows, as an alternative to the sliding bearing 20, that the end 19 is connected to the support arm 12 by an intermediate lever 22.
  • the intermediate lever is articulated on the support arm 12 on the one hand and the end 19 of the lever 17 on the other hand and allows a relative movement in the longitudinal direction of the support arm.
  • the winding spindle 2 with the sleeves 3 and coils 4 clamped thereon is rotatably mounted in the stationary frame 1 and driven by the drive roller 5.
  • the thread guide 7 is moved back and forth in the straight guide 8 by a reversing thread shaft 9. Downstream of the thread guide 7 in the thread run is the grooved roller 10, through which the thread is laid on the spool.
  • the traversing 6 with the reverse thread shaft 9 and the thread guide 7 and the grooved roller 10 and the drives, not shown, and also the driving roller 5 with its drive, not shown, are mounted in the carriage 11.
  • the carriage 11 has the support arm 12 for receiving the bearings, which extends along the winding spindle.
  • the carriage is movable in the straight guides 13.
  • the straight guides 13 consist of stamps 23 on the one hand and bushes 24 on the other hand.
  • the stamps 23 are fastened in the frame 1.
  • the sockets 24 slide as free of play and friction as possible - e.g. via embedded rollers or balls - on the punches 23.
  • Two guides - as can be seen in FIG. 5 - are provided at the end points of the diagonal of the slide 11, which enables stable guidance of the slide with the support arm 12.
  • the vertical movement of the slide and support arm 12 is brought about by the lever 17, which engages with its end 19 on the slide guide 20 of the support arm 12. It is mounted laterally from the carriage 11 - as shown in FIG. 3 - in a pivot bearing 18 on the frame.
  • the sliding bearing 20 is designed as a slot-shaped hole 28 in the longitudinal direction, in which hole a laterally projecting pin 27 of the lever 17 engages.
  • the other end of the two-armed lever 17 in this embodiment is bent vertically. At his end takes hold the force transmitter 14 at the force application point 21.
  • the force transmitter 14 is pivotally mounted in the pivot point 25 in order to take into account the mobility of the force application point 21 when the lever 17 is pivoted.
  • FIG. 5 shows that the piston rod 15 is articulated by the U-shaped yoke 26 at the force application point 21 of the lever 17.
  • FIG. 6 shows an embodiment similar to FIG. 2, in which the winding spindle 2 with the sleeves 3 and coils 4 clamped thereon is rotatably mounted in the fixed frame 1 and is driven by the drive roller 5.
  • the thread guide 7 is moved back and forth in the straight guide 8 by a reversing thread shaft 9. Downstream of the thread guide 7 in the thread run is the grooved roller 10, through which the thread is laid on the spool.
  • the traversing 6 with the reversing thread shaft 9 and the thread guide 7 and the grooved roller 10 and the drives, not shown, and also the driving roller 5 with its drive, not shown, is mounted in the carriage 11.
  • the carriage 11 has the support arm 12 for receiving the bearings, which extends along the winding spindle.
  • the carriage is movable in the straight guides 13.
  • the straight guides 13 consist of stamps 23 on the one hand and bushes 24 on the other hand.
  • the stamps 23 are fastened in the frame 1.
  • the bushings 24 slide with as little play and friction as possible - e.g. via embedded rollers or balls on the punches 23.
  • Two guides - as can be seen in FIG. 5 - are provided at the end points of the diagonal of the slide 11, whereby a stable guidance of the slide with the support arm 12 is made possible.
  • the vertical movement of the carriage and support arm 12 is brought about by the lever 17, which engages with its end 19 on the support arm 12 in a fixed joint 29.
  • the lever 17 is mounted on the side of the carriage 11 - exactly as in FIG. 3 - in a pivot bearing 18.
  • This pivot bearing 18 is seated at the end of an intermediate lever 30.
  • the intermediate lever 30 is articulated in the frame 31 in articulation 31.
  • the joints 18 and 30 lie at least approximately on the resultant of the support force in the joint 29 and the application force of the force transmitter 14 in the application point 21.
  • the other end of the lever 17, which in this exemplary embodiment is also two-armed, is bent vertically.
  • the force transmitter 14 engages in the force application point 21.
  • the force transmitter 14 is pivotably mounted in the pivot point 25 in order to take into account the mobility of the force application point 21 when the lever 17 is pivoted.
