Definitions

  • the present invention relates to a device for handling slats for warp threading machines, and means for storing the slats and with transport means for feeding them to a separating station at which the slats are separated for the purpose of making them available for the warp threading.
  • the invention is now to provide a device for handling slats for warp threading machines, which enables an uninterrupted automatic loading of the warp threading machine with slats.
  • this object is achieved in that the means for storing the lamella magazines for receiving lamella stacks and the transport means have a first path for feeding the full magazines to the separating station and a second path for returning the empty magazines from of the separating station, and that means are provided for transferring the empty magazines from the first to the second path.
  • the first path contains a feed rail sloping down towards the separating station and the second path contains a return rail sloping downwards away from the separating station, and the hand magazines are guided in a rolling or sliding manner in the feed and return rail.
  • two pairs of feed and return rails are provided, each of these pairs being assigned a means for transferring the empty magazines.
  • the drawing-in machine consists of a base frame 1 and of various assemblies arranged in it, each of which forms a functional module.
  • a warp beam carriage 2 with a warp beam 3 arranged on it can be seen.
  • the warp beam trolley 3 also contains a lifting device 4 for holding a frame 5, on which the warp threads KF are stretched. This clamping takes place before the actual pulling-in and at a location separate from the drawing-in machine, the frame 5 being positioned at the lower end of the lifting device 4 in the immediate vicinity of the warp beam 3.
  • the warp beam carriage 2 with the warp beam 3 and lifting device 4 is moved to the so-called upgrade side of the pulling-in machine and the frame 5 is lifted up by the lifting device 4 and then assumes the position shown.
  • the frame 5 and the warp beam 3 are moved in the longitudinal direction of the base frame 1. With this shifting, the warp threads KF are guided past a thread separation group 6 and separated and divided in the process. After division, the warp threads KF are cut off and presented to a pull-in needle 7, which forms part of the so-called pull-in module.
  • the sectioning device used in the USTER TOPMATIC warp knitting machine (USTER - registered trademark of Zellweger Uster AG), for example, can be used for dividing the warp threads.
  • a monitor 8 which belongs to an operating station and is used to display machine functions and machine malfunctions and for data input.
  • the operator station which forms part of a so-called programming module, also contains an input stage for the manual input of certain functions, such as creeper, start / stop, repetition of processes, and the like.
  • the drawing-in machine is controlled by a control module containing a control computer, which is arranged in a control box 9.
  • this control box contains a module computer for each so-called main module, the individual module computers being controlled and monitored by the control computer.
  • the main modules of the drawing machine are, in addition to the modules already mentioned, drawing module, yarn module, control module and programming module, the strand, the lamella and the sheet module.
  • the warp threads and the individual elements in which the warp threads are to be fed are fed in on the upgrade side, and the so-called dishes (strands, lamellae and sheets) with the drawn-in warp threads can be removed on the tear-down side.
  • the frame 5 with the warp threads KF and the warp beam carriage 2 with the warp beam 3 are moved past the thread separation group 6 to the right, the pull-in needle 7 successively taking out the warp threads KF stretched on the frame 5.
  • the warp thread guard slats LA Immediately behind the plane of the warp threads KF are the warp thread guard slats LA, behind them the healds LI and even further behind the reed.
  • the lamellae LA are stacked in hand magazines, and the full hand magazines are hung in inclined feed rails 11, on which they are transported to the right, towards the pull-in needle 7. There they are separated and brought into the feed position. After pulling in, the lamellae LA arrive on lamella support rails 12 on the dismantling side.
  • the strands LI are lined up on rails 13 and manually or automatically shifted to a separation stage on them. Then the healds LI are individually brought into their retracted position and, after they have been drawn in, distributed to the corresponding heald frames 14 on the dismantling side. The reed is also moved past the pull-in needle 7 step by step, the corresponding sheet gap being opened for the feed. After it has been drawn in, the sheet is also on the dismantling side. To the right of the heald frames 14 is a part of the reed WB. This representation is to be understood purely for illustrative purposes, because the reed differs from the one shown The position of the frame 5 is of course on the upgrade page.
  • a so-called crockery trolley 15 is provided on the dismantling side. This is inserted together with the slat support rails 12, heald frames 14 and a holder for the reed attached to the base frame 1 in the position shown and carries the dishes with the drawn-in warp threads KF after being drawn in. At this time, the warp beam carriage 2 with the warp beam 3 is located directly in front of the dishwashing carriage 15. Now, using the lifting device 4, the dishes are reloaded from the dishwashing carriage 15 onto the warp beam carriage 2, which then carries the warp beam 3 and the drawn-in dishes and to the relevant weaving machine or can be moved to an interim storage facility.
  • FIGS. 2a, 2b and 3 show an overall view of this partial module in a side view (FIGS. 2a, 2b) and in a front view (FIG. 3) in the direction of arrow III of FIG 2a.
  • the side view is divided into two sheets, wherein FIGS. 2a and 2b are to be thought of as abutting along the line A-A drawn in FIG. 2a on the far right and in FIG. 2b on the far left.
  • the slat magazine sub-module essentially consists of a movable elongated frame GE, in which the feed rails 11 for the hand magazines with the slats LA (FIG. 1) are mounted.
  • the sub-module in FIGS. 2a and 2b is rotated through 180 °; its total length is about 3 meters.
  • the feed rails 11 are formed by profile rails with a C-shaped cross section, into which elongated hand magazines 16 are hung. 4 and 5, these consist of a rail 18 carrying transport rollers 17, a handle 19 connected to the rail 18 and a slat rod 20 connected to the handle 19, on which the slats LA are lined up .
  • the feed rails 11 run from the loading side of the submodule whose unloading side, that is the separating station at which the lamellae LA are separated, slants downwards so that the hand magazines 16 loaded with lamellae LA automatically roll to the separating station, which is located at the left end of the sub-module in FIG. 2a.
  • return rails 21 are provided in the frame GE for returning the empty hand magazines from the separating station to the loading side. These run obliquely downwards away from the separating station, so that the empty hand magazines 16 roll back by themselves.
  • the empty hand magazines are transferred to the return rails 21, which will be described later with reference to FIGS. 6 and 7.
  • the foremost part of the feed and return rails 11 and 21, which adjoins the separating station is designed as a pivot rail 22 which can be pivoted optionally into the feed path or into the return path and whose length corresponds to the length of a hand magazine 16. It is therefore only ever located in the hand magazine 16 in the swivel rail 22, its entry and exit into and from the swivel rail being detected by sensors 23 and 28.
  • the hand magazine 16 in the swivel station 22 abuts a stop with the tip of its rail 18 (FIG. 4) and is thereby fixed in the swivel rail.
  • the individual lamellae LA are transferred to the separating station by moving the lamella stack lined up on the lamella rod 20 against the free end of the lamella rod. This displacement is carried out by a pneumatic cylinder 24 which drives a plunger 26 guided in a C-profile 25.
  • This plunger is provided on its front part pressing against the stack of lamellae with a hinge-like driver finger 27.
  • the driver finger is held in its working position by spring force, in which it projects at right angles from the plunger 26 and presses against the lamellae LA.
  • the swivel rail 22 is swiveled into the return path, as a result of which the empty hand magazine 16 is transferred to the return rail 21 and rolls back to the right against the loading side of the lamella module.
  • This movement is made by one Sensor 28 monitored on the return rail 21.
  • the swivel rail 22 is swiveled into the feed path, so that a new full hand magazine 16 can roll into the swivel rail 22.
  • the plunger 26 with the driver finger 27 is still in its foremost position.
  • the pneumatic cylinder 24 is retracted.
  • the driver finger 27 abuts against the lamellae LA and, because of its hinge-like attachment to the plunger 26, is pushed aside to the extent that it can slide along the lamellae.
  • the frame GE has a central longitudinal rail 29 on which electrical connections 30 for the various sensors and pneumatic connections 31 for the various pneumatically driven adjusting elements are arranged.
  • 29 supports 32 for the C-profiles 25 are attached to the central longitudinal rail 29.
  • Each swivel rail 22 is articulated to the central longitudinal rail 29 on its end face adjacent to the separating station and is adjustable via a pneumatically driven lever 33 which is fastened to the frame GE.
  • FIG. 3 shows the different positions of the two swivel rails 22, the swivel positions being drawn approximately in the region of the sensor 23, that is to say at the location of the maximum deflection of the swivel rails 22, for a clearer illustration. This is the place where the respective end of the swivel rails 22 is aligned with the associated feed or return rail 11 or 21.
  • the swivel rail 22 is in the fully extended position in the feed path, the position shown in broken lines corresponds to the return path.
  • the swivel rail 22 is in the fully extended position in the return path, the position shown in broken lines corresponds to the feed path.
  • the left half shows a full hand magazine 16 with lamellae LA, which are pushed against the viewer by the pneumatic cylinder 24 via plunger 26 and driver 27.
  • the right half shows an empty hand magazine 16, the slats of which have already been processed.
  • the frame GE is provided with wheels 34 which run in corresponding rails 35.
  • the frame GE and thus the entire slat module are mobile on the one hand, that is to say they can be moved into and out of the drawing-in machine, and on the other hand can be fixed in the drawing-in machine in its working position.
  • FIGS. 6 and 7 show the connection between the feed and return rails 11 and 21 on the one hand and the swivel rail 22 on the other hand, FIG. 6 being an enlarged detail from FIG. 2a and thus a side view and FIG. 7 a plan view in the direction of the arrow VII of Fig. 6 shows.
  • a pivotable stop flap 36 for the hand magazines 16 is arranged on the end of the feed rails 11 facing the swivel rail 22.
  • An arcuate groove 37 is milled into this stop flap, into which a locking bolt 38 engages, and which has a step 39 recessed at its upper end with respect to the base of the groove.
  • the locking bolt 38 is arranged on one end face of a cylinder 40 which is resiliently mounted in a bore in the central longitudinal rail 29 and its length corresponds to the depth of groove 38 plus gradation 39.
  • the locking bolt 38 projects with its entire length into the groove 37 and step 39 and thereby locks the stop flap 36, as a result of which this occurs in the adjacent feed rail 11 in the transport direction, the foremost hand magazine 16 is prevented from rolling further (FIG. 6). If the swivel rail 22 is then swiveled into the feed path and aligned with the feed rail 11 (FIG. 7, upper half), then the swivel rail 22 also hits its side surface facing the central longitudinal rail onto the cylinder 40 and presses it against the force of its spring into its bearing bore, as a result of which the locking bolt 38 is pulled out of the step 39 of the groove 37.
  • the corresponding adjustment path of cylinder 40 and locking pin 38 is somewhat greater than the depth of the step 39, so that the locking pin 38 no longer protrudes into the step and the stop flap 36 is therefore no longer locked.
  • the stop flap 36 is pressed upwards by the foremost hand magazine 16 and this can roll into the swivel rail 22.
  • the pressure of the swivel rail 22 on the cylinder 40 is released and the locking bolt 38 can snap back into the step 39 and lock the stop flap 36.
  • the lamella module In its working position, the lamella module is detachably coupled to the drawing-in machine. In this working position, the loading of full magazines and the removal of the empty magazines takes place in the drawing-in machine, from which the lamella carriage is only removed for maintenance or service work.
