Definitions

  • the invention relates to a device for Combing cotton and cotton-like fibers with a feed device for feeding Fibers, using pliers to hold the fibers during the comb, with a round comb, which is a comb segment for combing the fibers held by the pliers, with an essentially positionally stable tear-off device for pulling out those combed by the round comb Fibers from the pliers and for soldering the from the pliers delivered beard with the rear end of the Kammzuges, consisting of at least one lower Tear-off roller and an axially parallel upper tear-off roller, with both tear-off rollers making a mit step motion perform, with a fixed comb to the rear Comb the pulled fibers and with a trigger device.
  • the tear-off rollers are arranged in a stable position outside the path of movement of the comb tips of the circular comb.
  • the tear-off roller pair consisting of a lower and an upper tear-off roller, is immediately adjacent to the pliers and the circular comb.
  • the lower tear-off roller is located between the path of movement of the comb tips of the circular comb and the upper tear-off roller and, together with the upper tear-off roller, forms the clamping gap for the comb pull.
  • the pliers are swinging in two directions stored.
  • the pliers are raised as a unit so that the just combed fiber beard reaches the nip of the tear-off roller pair. During this movement, the pliers also approach the tear-off nip horizontally.
  • the section of the sliver fed back at this time is overlapped with the tips of the new, combed fiber beard, pressed into the nip of the tear-off rollers and pulled in the pull-off direction by the tear-off rollers.
  • the fixed comb is inserted into the end of the newly combed fiber beard and combs out this free piece of fiber.
  • Another major disadvantage is that too free end of the beard that has just been combed with relatively high speed, with the free fiber tips moving forward, over long distances and in precise defined position on the returned end of the ridge must be placed.
  • Another disadvantage of the known device is that between the tear-off roller pair and the take-off rollers, due to theippo movement of the tear-off rollers, an uncontrolled formation of wrinkles occurs, which additionally leads to disturbances in the combing process.
  • the invention is based on the object, a Device for combing cotton or cotton-like To create fibers where the through the round comb combed fiber beard between combing and soldering be guided precisely and with high precision can.
  • the device found so can be modified that the setting options regarding the degree of overlap, the tear-off length and the feed speed even during the run of the Machine are given.
  • This configuration makes it possible to place the upper tear-off roller very close to the path of movement of the comb tips of the circular comb.
  • the clamping gap is thus very close to the area in which the fiber beard has been combed out by the circular comb.
  • the pivoting movement of the lower tear-off roller around the lower section of the upper take-off roller displaces the nip against the fiber tips of the newly combed fiber beard.
  • the returned end of the comb is held by the air flow following the comb segment on the lower take-off roller in such a way that a large open angle is available for inserting the newly combed fiber beard.
  • this new device enables extremely low device effort a significant Increase the working speed of the combing machine. At the same time it is possible to check the quality of the crest through an exact positioning of the fiber ends of the Comb and the newly combed fiber beard clearly increase.
  • the bearing of the lower leg of the pliers and in principle the bearing of the feed rollers according to claim 2 to be fixed to the frame.
  • the entire pliers unit can are basically arranged in a stable position. The ones to be moved Masses are reduced to a minimum. The between two passes of the comb segment to be carried out mechanical movements are limited to the Swinging motion of the lower tear-off roller, which leads to this optimized laws of motion can be executed.
  • a low device effort is due to the design reached according to claim 4.
  • the design of the device according to claim 5 enables on the one hand an optimization of the mit step movement the tear-off roller and a matching one Movement of the second lower tear-off roller for guidance the ridge to the trigger.
  • the optimal drive device for the pivoting movement of the lower tear-off rollers is defined.
  • the arrangement of claim 7 also allows control of the uniformity of the ridge according to a manually or automatically specified program.
  • the so-called fixed comb according to claim 8 pivotable about the upper tear roller to arrange. This reduces the device effort with optimal operation of the fixed comb.
  • Claim 10 defines the criteria for determining the form of movement of the second lower Tear-off roller with regard to its swinging movement around the upper take-off roller with wrinkle-free comb loop are to be considered.
  • the basic structure of the device should be based on FIG. 1 to be discribed.
  • the circular comb 1 is in a conventional manner in the frame the combing machine is rotatably mounted and is in itself driven in a known manner.
  • the round comb 1 has a Comb segment, the tips of its combs on a circular Orbit around.
  • This pliers 3 is preferably in Circumferential direction of the circular comb 1 and radially to the same adjustable.
  • This pliers 3 is a swinging in the usual way movable top pliers 4 assigned a clamping surface for the fiber beard to be combed and a deflecting nose, which are directed towards the path of the comb tips is owns.
  • the feed rollers 15 are the lower and upper pliers 3.4 assigned in a known manner. You become addicted of the respective comb game and the respective Delivery quantity per comb game moved step by step.
  • This upper tear roller 5 is at least a lower one Tear roller 7 assigned to the lever on the Axis of the upper tear roller 5 is pivotally mounted. Both tear-off rollers 5.7 together form the one for the Soldering process necessary for the crest 8.
  • the lower tear roller 7 is from a position in which they are completely outside the trajectory of the Comb tips of the circular comb 1 is in one position within the trajectory of the comb tips, close to the clamping surfaces of the collet 3 movable.
  • the second lower tear roller 6 (it could also be referred to as a guide roller) can also be pivoted about the axis of the upper tear roller 5.
  • the ridge 8 between the nip of the tear-off rollers 5, 7 and the take-off device 9 is defined and guided without creases.
  • the ridge 8 is at its rear end in Pinch gap of the tear-off rollers 5,7 held.
  • the ridge 8 between tear-off rollers 5, 7 and the take-off device 9 becomes looped over the second lower tear roller 6 performed in a wrinkle-free and untensioned form.
  • the rear end of the ridge 8 is fed back by a corresponding rotary movement of the tear-off rollers 5, 7.
  • This returned end of the ridge 8 is also pressed down by the air flowing in after the ridge segment, so that a large open angle is available for inserting the newly combed fiber beard.
  • Both fiber whiskers are superimposed in a defined manner and are connected to one another by pressure (soldered) by means of the clamping gap which moves towards the overlap section due to the rolling movement of the tear-off roller 7.
  • the tear-off rollers 5, 7 then start in this position (according to FIG. 1) with their rotary movement in the take-off direction and with the simultaneous backward swinging movement the further pulling off of the combed fiber beard.
  • the fixed comb 10 is inserted around the upper tear-off roller 5 with its tips into the fiber beard and combs out the rear end of this fiber beard.
  • the new end of the ridge is from this fiber beard solved and is between Figure 2 in the nip upper and lower tear roller 5,7 held.
  • the course of f VAR in the diagram (FIG. 4) represents the distance function from the clamping line of the tear-off rollers 5, 6 and the clamping line of the take-off rollers 9 a wrinkle-free guiding of the ridge move necessary movement of the ridge between the tear-off rollers f GES .
  • the amount of funding required for the combing process the upper tear roller 5 can be determined.
  • the programmable electric drives available today enable optimum movement of the described working elements with minimal mechanical effort. So you can carry out both the swinging movement and the rotational movement of the tear-off rollers 5,6,7 by means of computer-controlled stepper or servo motors.
  • the fixed arrangement of the pliers 3.4 enables the tear-off length even during the combing process set within relatively large limits.
  • the spindle-nut gear 11, 12 can be controlled manually or by means of Motor (not shown) are operated.
  • Such drive arrangements for the individual work elements also allow certain control processes with regard to the uniformity of the ridge 8 to be carried out while the machine is running.
  • the upper tear-off roller 5 must be stored in any position test. In the sense of optimizing all movements, it may also be expedient to move this upper take-off roller 5 slightly radially to the circular comb 1 or towards the pliers 3, 4.
