Definitions

  • the invention relates to a device for automatically connecting threads, consisting of a frame with a plurality of thread clamps and a stepwise horizontally movable carriage on which a thread connecting device is provided, a method for connecting threads and a use of the device.
  • bobbin changer a device which allows threads to be taken from 50 to 100 bobbins. It is used to manufacture a test knitted tube, which is composed of short sections according to the number of bobbins presented (W. Stein, Textile Horizons, (1988) pages 40-42). The sample stocking is used for a visual assessment or as a template for a colorimetric evaluation of the sections after it has been colored.
  • a program-controlled device for connecting filament yarns is known from DE-A-33 36 202. Then a first stationary thread is connected to a second running thread by air swirling and is only separated from the running thread when both threads have the same speed. The ends of the threads of the supply spools are held in clamping points which are designed as bolts and are pressed mechanically by spring pressure against a support surface. The uniform mechanical loading of many clamping points can only be accomplished with great effort.
  • the object of the invention is to provide both an improved device and a method for the automatic, safe change of a large number of threads of different bobbins and their step-wise connection.
  • each thread clamp is assigned a thread guide tube at a certain distance perpendicular to the thread pull, said thread guide tube being connected to a vertically movable suction bar.
  • the thread is permanently pre-tensioned until it is removed for thread retraction and cannot spring back or evade in any way.
  • the thread is expediently held by suction until it is released with a thread separating device.
  • the thread guide tubes are fastened in a profile rail, equipped with a thread guide eyelet at the end of the thread inlet and preferably consist of ceramic tubes. This has the advantage that the thread is drawn in cleanly when it is sucked in.
  • the segment-by-segment arrangement of the suction blocks has the advantage that a certain number of threads is kept under a uniform tension and, overall, works with less energy can be.
  • Each suction block is equipped with an injector nozzle and a thread discharge hose.
  • the lifting plate has the advantage that after the suction bar has been docked onto the thread guide tubes, all thread clamps are relieved by the lifting plate, which enables general thread pulling.
  • a pneumatic cylinder arranged on a slide as the threading arm, which is connected to the suction bar and can take over the free end of the thread between the entrance of the thread guide tube and the thread clamp.
  • the pneumatic cylinder loads the thread clamp before a position shift and only releases it when the threading arm is in the suction position in order to load the next clamp after the position shift.
  • Pneumatic pick-up and transport of the thread has proven to be more advantageous and safer than a mechanical gripper arm.
  • a thread is expediently threaded into the threading arm by means of an injector mounted at the outlet by suction.
  • Both a thread separating device and a thread marker are provided on the carriage itself. After the thread connection has been completed, the thread cutting device cuts off the "old" thread behind the connection point.
  • the suction bar is docked to the thread guides.
  • a change of overlay or supply is the change in a creel with new coils.
  • Thread ends lying in the area of the openings of the thread guide tubes are sucked in and, by the general release of the thread clamps, the new templates, which have been connected to the old thread rest, are brought into the operating position by suction.
  • the actual work, change process is released.
  • all thread clamps are relieved by the lifting plate.
  • the thread clamps are activated to prevent unthreading.
  • FIG. 2 parallel threads coming from a gate are shown and because of the overview only the threads 7,7 'are designated.
  • the thread 7 ' is already connected to thread 15 and lies in the slot 13 from which the thread residue 15' is sucked off after cutting with the thread separating device 9.
  • a new thread 7 is in the slot 12 and is connected to the thread 15.
  • the thread 15 passes through a thread guide 20 and 21 arranged in front of and behind the thread monitor 14.
  • the threading arm 11 is shown with its mouth between the thread guide tube 6.
  • FIG. 3 three sections 10 ', 10' 'and 10' '' of the suction bar 10 are shown. Each of the sections 10 ', 10' 'and 10' '' is provided with an injector and an exhaust pipe 16. For the sake of clarity, suction tubes 16 and 16 'are only shown for the sections 10' and 10 '' '.
  • Each suction bar 10 includes a piston 17 with a flexible air connection, not shown. The suction bar 10 is displaceable in the vertical direction, indicated by a double arrow.
  • the thread separating element 22 serves to release the threads 7. A soldering iron can serve as the thread separating element 22.
  • the threads 7 held by the suction bar 10 are released individually by the thread separating device 9 due to the gradual displacement of the carriage 2.
  • the released thread piece 7 can be taken over by the threading arm 11 by suction.
  • the threading arm 11 can feed the thread into the thread connecting device 8.
  • the lifting cylinder 23 is for the actuation of a thread clamp 5; a lifting plate 24 is provided for all thread clamps 5.
  • threads 7 are held by thread clamps 5 and guided over thread guide tubes 6 before starting.
  • the threads 7 hang down about 10 cm with their free ends.
  • the connected thread 15 leads through the thread connecting device 8 and past the thread monitor 14, for example to a circular knitting machine, not shown.
  • the threading arm 11 pivots towards the thread clamp 5, and the thread 7 is drawn in by the threading arm 11.
  • the thread clamp 5 is raised pneumatically by the piston 17; the thread 7 is pulled into the slot 12.
  • the thread connecting device 8 for example a thread splicer, is actuated and the thread is thus connected to the thread 15 of the knitting machine by a gate, not shown.
  • the knitting machine is started and stopped again after a predetermined time, corresponding to the size of the desired knitting section.
  • the piston 17 is vented and the thread 7 is held again by the thread clamp 5.
  • the thread 7 is changed from the slot 12 into the slot 13 by the thread lifter 18 and separated after the thread connection by means of the thread separating device 9.
  • a pair of scissors or a soldering iron can serve as the thread separating device 9.
  • the thread connecting device 8 mounted on the carriage 2 is moved by the motor 3 to the next thread location, as a result of which the cycle with the thread 7 ′ starts again.
  • the carriage 2 moves to the zero position.
  • the change machine is restarted.
  • the suction bar 10 is raised and coupled to the thread guide tubes 6.
  • the thread sections, which are arranged between thread clamp 5 and thread guide tube 6 more or less lying around are now sucked into the thread guide tube 6.
  • the lifting plate 24 opens all the thread clamps 5, whereby all threads are pulled through until all the connection points old / new template are pulled through.
  • the lifting plate 24 moves away.
  • the thread clamps 5 are thereby set in function.
  • the suction bar 10 is lowered, whereby the readiness for the gradual thread change is created.
  • the carriage returns to the starting position.
  • the device according to the invention makes it possible to carry out thread take-off according to selectable lengths from a large number of bobbins.
  • a splicer or knotter known per se for the first time it is possible, depending on the design of the machine size, to connect more than 100 supply spools, the threads of which are pre-sorted in the device, to one another fully automatically.
  • the number of change positions can be specified to the machine.
