Definitions

  • the invention relates to a winding device which consists of a two-armed spool lever which is pivotally mounted in the machine frame about a stationary axis and which has a releasable spool sleeve fastening and a stationary spool drive which acts on the circumference of the spool.
  • a winding device for winding a thread on a bobbin tube with the features specified in the preamble of claim 1 is already known.
  • coils are alternately produced on two mutually parallel coil axes.
  • the two bobbin levers are rotated further with respect to the drive roller and the finished bobbin is lowered, while at the same time an empty sleeve clamped between the centering plates of the second bobbin lever is placed on the drive roller.
  • the invention is based on the technical object, in particular to simplify and facilitate the process of removing or guiding the full bobbin from the bobbin case fastening in the bobbin lever and, if appropriate, the transfer of the full bobbin to a receiving and transport device. It is a further object of the invention to lift the full bobbin from its stationary drive, a driving roller, when the winding process is complete, to brake it and to release it from the bobbin tube attachment after it has come to a standstill.
  • the coil is to be picked up by a guide device and guided into a user-friendly position or directly into a receiving and / or transport device for the full coils.
  • the prerequisites are to be created by the invention to automate the bobbin changing process in substantial parts or in total B.
  • the full coil is lifted from its drive and brought into a latched position of the coil lever and the coil change then takes place automatically.
  • the invention achieves this object by means of a winding device, on the U-shaped coil lever of which a guide device consisting of two running rails is pivotably mounted essentially concentrically to the centering plates.
  • the running rails can be positioned in two swivel positions.
  • the running rails are pivoted into their lower pivot position when the coil has reached its final diameter and the coil lever has therefore been locked in an upper pivot position (change position).
  • the runners In their lower swivel position, the runners have a slope and reach under the outermost ends of the bobbin tube of the full bobbin.
  • the bobbin tube is released from the bobbin lever by axial movement of at least one of the two centering plates, and the ends of the bobbin tube roll on the running rails into a position in which the bobbins can be gripped comfortably by hand or by a robot.
  • the running rails open into a receiving and transport device.
  • the drive roller lies axially between the rails.
  • the running rails can be bent upwards at their rear ends, with which they engage under the coil sleeves, and can thereby be designed as a sleeve travel limiter.
  • one of the arms can have a joint in a known manner for releasing the bobbin case fastening by pivoting it sideways.
  • An embodiment of the coil lever is preferred, in which the arms together with their base, for. B. pivot axis, form a substantially rigid U-shaped frame.
  • the centering plates arranged in the region of the free arm ends can then both be moved in the axial direction with respect to the laterally non-pivotable arms, this movement being directed in opposite directions in accordance with the function of the centering plates as clamping elements.
  • the axial movement of the centering plate can advantageously be coupled to the pivoting movement of the guide device in such a way that it is only possible in the pivoting position of the guide device in which the running rails or their tube travel limiters are located under the ends of the winding tube. This ensures that the full spool is not released from the centering plates and the spool lever before the runners reach under the ends of the spool sleeve.
  • An embodiment which is particularly suitable for automation is characterized in that the pivoting movement of the running rails into their lower pivoting position also brings about the axial movement of the centering plates in the sense of loosening the coil sleeve. It is reversed by swinging ken the guide rails in their folded position causes the axial movement of the centering plate in the sense of clamping the empty bobbin tubes.
  • the bobbin lever 3 is pivotally mounted in the bearing block 2 of the machine frame 1. In a known manner, it has a damping bracket 5 which interacts with a sliding block 37.
  • the spool lever 3 consists of two substantially similar arms, which together with the pivot axis 27 form a rectangular frame that is open at the front. This has a centering plate 29 (FIG. 2) on each of the free arm ends and on the inner sides thereof, between which the winding tube 18 is clamped.
  • bobbin drive 13 in the form of a drive roller, a traversing mechanism 14 and a traversing thread guide 15 guided therein, which guides the thread 16 reaching the winding point via the deflection roller 17 to the winding point.
  • the spool lever 3 is shown in the spool change position 38.
  • the full bobbin 25 is lifted from the drive roller 13, the bobbin lever 3 is locked in this position by the sliding block 37 which is latched into the recess provided for this purpose in the damping bracket 5.
  • the guide device 8 which consists of the two running rails 9 with the stops 10 and the sleeve travel limiters 36 and the connecting bracket 12 and is provided on the open side with handles 11, is arranged within the arms of the spool lever 3 so as to be pivotable about the centering plate axis.
  • the bracket 12 is not set in the extension of the rails 9, but angled for reasons of space. It is dimensioned such that the full spool - as indicated by dash-dotted lines in Fig. 2 - finds space within the bracket 12 without tarnishing.
  • the runners 9 are in the lower pivot position, the working position 22.
  • the runners 9 have a slight slope to the operating side of the winding machine, which, when the centering plate 29 is released, leads to the released ends of the winding tube 18 sit on the sleeve travel limiters 36 and the full bobbin 26 rolls forward until the bobbin sleeve ends abut against the stops 10. It is essential that the clamped sleeve ends are only released when the travel limiters 36 are below them.
  • the guide device 8 as indicated by dash-dotted lines and identified by 20, is in the folded-up position relative to the bobbin lever during the winding travel.
  • This position based on the bobbin lever 3, it maintains until the end of the winding process, so that it has then assumed the position designated by 21. Only when the bobbin 25 is lifted off and the bobbin lever 3 is engaged is it then lowered into the working position 22. To ensure trouble-free operation, it has proven to be expedient if the guide device 8 brought into the upper swivel position 21 after inserting the empty tube at the end of the bobbin change is locked in this position and is only released after the bobbin lever 3 into the bobbin change position 38 was brought.
  • the guide device 8 With a corresponding constructive design of the centering plate attachment, it is possible to use the guide device 8 according to the invention also on winding devices of known type, in which one or both arms of the spool lever can be swiveled sideways by the centering plate to release the winding tube. According to the invention, however, the use of rigid coil lever arms which can only be moved together about their pivot axis 27 is preferred, in which case the centering plates are then made movable in the axial direction.
  • FIG. 3 An advantageous embodiment of a device for axially displacing a centering plate is shown in FIG. 3.
  • the illustration shows a horizontal section through the device and in the centering plate axis.
  • the arm of the spool lever 3 has a lateral recess, the housing 4, which is concentric with the centering plate 29 and in which the device is accommodated.
  • a first, fixed pressure piece 32 is provided in the lateral bottom of the housing in a precisely fitting recess and connected to the housing 4 by means of stud bolts 40.
  • a second pressure piece 31 is provided, which, together with the bearing pin 39, forms the bearing of the centering plate and is secured against rotation, but is axially movable.
  • a key 41 practically occupying its entire free length, which fits into the keyways 42 in both pressure pieces 31, 32 takes hold. As a result, the latter are secured against rotation relative to the spool lever 3; however, only the movable pressure piece 31 can move in the axial direction.
  • Both thrust pieces 31, 32 are seated in the control hub 33, which is firmly connected to the running rails 9.
  • the control hub is connected to the pressure piece 31 on the one hand and to the pressure piece 32 on the other hand by circumferential guides, of which at least one circumferential guide is a threaded connection 34.
  • the circumferential guides or threaded connections allow the control hub 33 to rotate. If both circumferential guides are threaded connections, these threaded connections have opposite pitches.
  • the threaded connections can be designed as two intermeshing thread grooves.
  • the pins can be fitted with smooth-running, cylindrical rollers.
  • one guide pin per pressure piece is sufficient, but several, for example three, guide pins per pressure piece 31, 32 can also be provided; but then they must lie with their axes in a common plane perpendicular to the centering plate axis and the grooves must be distributed accordingly.
  • One advantage of such an embodiment is, for example, that when the centering plate is released from the pivoting of the guide device 8 in the working position 22 by appropriate design of the grooves - for example for the first pivoting phase they can run in a plane perpendicular to the axis and only by one generate the corresponding movement in the second swivel phase, the lateral movement - the centering plate is only released in the last swivel phase.
  • the spring lever 35 has the task of generating a bias such that the rails are held in their upper pivot position 21. It is advantageous to have a fuse that engages in both end positions 21 and 22.
  • FIG. 4 shows a further advantageous device for axially moving the centering plate 29.
  • the stationary pressure piece 32 is fastened with screws 40 in the housing 4 of the coil lever 3.
  • the bearing pin 39 In its central bore slides axially displaceably the bearing pin 39, on the right end section of which the centering plate bearing 30 is fixed in the axial direction.
  • a second pressure piece 31 is fixed radially (parallel key 41) and axially (snap ring 49) on the bearing pin 39 and can be axially displaced together with it in the bore of the stationary pressure piece 32.
  • the centering plate 29 is also carried along with the pressure piece 31 when the bearing bolt is displaced laterally.
  • each of the two pressure pieces 31, 32 is secured on the bearing pin 39 with its own feather key against rotation. Between them is a snap ring 49 for axially securing the pressure piece 31; it should be pointed out that the axial fixation of the pressure piece 31 required according to the invention is carried out here only by way of example by means of a snap ring, other means can serve the same purpose.
  • the pressure piece 31 is connected to the free end of a parallel spring 44 which sits at the other end with the aid of the spring holder 45 and the screw 55 on the coil lever 3.
  • the parallelism of the two spring leaves is achieved by the spacer 46 and the fastening piece 47.
  • the parallel spring presses the centering plate 29 against and into the winding tube 18.
  • the rotatable control hub 33 is connected to the pressure pieces 31 and 32 via a circumferential guide.
  • the circumferential guide between the stationary pressure piece 32 and the control hub is formed by a collar on the pressure piece 32 which lies in a normal plane and which meshes with a circumferential groove of the control hub 33.
  • the groove is formed by a cover 50 which is screwed to the control hub by stud screws 51.
  • the control hub 33 is fixed axially with respect to the stationary pressure piece 32 by means of the groove and collar 52 and only the rotary movement is permitted.
  • the circumferential connection between the control hub 33 and the pressure piece 31 is formed by a thread-shaped curve piece 53 in the control hub 33 and a nose 54 which is fastened to the pressure piece 31 and meshes with the curve piece 53.
  • the control hub 33 is firmly connected to a running rail 9. By lowering the running rail into the lower swivel position, the control hub 33 is rotated counterclockwise as seen from the right. As a result, the pressure piece 31 with the bearing pin 39 and bearing 30 is pushed to the left and the bobbin tube 18 is released against the parallel spring force 44.
  • control hub 33 By pivoting the running rail into the upper pivot position, the control hub 33 is rotated in the opposite direction of rotation.
  • the right pressure piece 31 and with it the centering plate 29 is through the threaded connection Extension of the curve 53 and nose 54 and by the force of the parallel spring 44 is shifted to the right and the winding tube is clamped.
