Definitions

  • the invention relates to a movable cleaning and operating device for textile machines, in particular for high-speed ring spinning machines, according to the preamble of claim 1, and to a method for cleaning and operating textile machines, according to the preamble of claim 13.
  • the desired functions can be carried out with a single cleaning and operating device, which not only has advantages in terms of the energy consumption involved, the rails and electrical lines to be installed, but also prevents it in principle, that conflict situations can occur with other devices.
  • a particularly efficient cleaning can be provided by literally engaging the blowing nozzles or the suction nozzles in the work elements to be cleaned and virtually enclosing them, so that the cleaning can be carried out precisely at the points at which the fiber fly arises.
  • contour nozzles in the space between the pendulums which are adapted to the surface of the drafting rollers for cleaning the drafting system to allow carriers to intervene and at the same time remove the cleaning rollers required for this purpose to clean them using a wire brush roller attached to the cleaning device.
  • the cleaning rollers can be lifted off with a separate operating arm and transferred to the cleaning position, in which case a rotation drive of the cleaning rollers can then be effected by contact with the wire brush roller, which in connection with suction extraction of the contact point between the wire brush roller and cleaning roller for cleaning the cleaning roller from wound fiber fly leads.
  • the centrifugal effect can be advantageously used with a fast drive of the cleaning rollers, the wire tips of the wire brush roller additionally lifting off the fiber winding.
  • the existing air output can be used several times by switching the air flows and, in addition to suction and / or blowing, a further operating function can be provided.
  • a high-pressure blower with a comparatively low air volume with a low-pressure blower with a comparatively large air volume
  • the high-pressure blower being used for the targeted cleaning of the working elements of the textile machine and the low-pressure blower, for example, acting on a footwell nozzle or for that Vacuuming the cleaning roller in the cleaning position is used.
  • a suction or blowing space in the area of the cops is provided with a whirl knife which can be triggered in a targeted manner.
  • the cut off ne thread residue can be removed from the associated suction or blow arm, so that it cannot be wrapped and thereby avoidable disturbances can be avoided. Due to a special construction of the whirl knife, even at high rotational speeds of the spindles of, for example, 25,000 revolutions per minute and the spinning of polyester, sticking with subsequent burning of the whirl knife can be avoided without the rotational speed having to be reduced for cutting off.
  • the spring element according to the invention can also consist of an impact surface, for example made of metal, which acts immediately after the cutting when the whirling knife rebounds.
  • the guiding elements for the whirl knives accelerate the whirl knives in the area of the cutting edge in the circumferential direction when the cops are approached, wherein the rebounding of the whirl knife can also be used to bring the whirl knife back into the starting position.
  • the triggering impact bar is expediently under a spring preload acting in the actuating direction of the whirling knife, while the trigger rod can be returned to the ready position before triggering by pneumatic or electrical means.
  • the movement of the whirl knife can at the same time be given a vertical component due to a correspondingly designed guide profile, which on the one hand increases the service life of the whirl knife and increases the safety of the cut.
  • the whirling area can be cleaned continuously as soon as the ring bench has reached the corresponding height, the cleaning intensity can be ensured to the desired extent even with very long textile machines if six or even twelve work units such as spindles are subjected to simultaneous cleaning by the cleaning and operating device according to the invention.
  • a cleaning and operating device 10 has a frame 12 and can be moved on a floor-side travel rail 14.
  • a suction and / or blowing unit 16 is arranged, to which a suction and / or blowing arm 18 for whirl cleaning, as well as a suction and / or blowing hose for the drafting area is connected.
  • a suction nozzle 19 is connected for floor cleaning.
  • Another operating arm is designed as a gripping arm 22 and is suitable for lifting a cleaning roller 28 lying obliquely above a drafting unit 24 of a textile machine 26 and pivoting it into a cleaning position 30.
  • the cleaning roller 28 bears against a wire brush roller 32, which is rotated by a drive device 34 and in turn rotates the cleaning roller 28.
  • the fibers loosened by the engagement of the wire ends of the wire brush roller 32 in the cleaning roller are detected via a collecting nozzle 36 and suctioned off from the suction and / or blowing unit 16 via a hose connection (not shown).
  • the gripper arm 22 is pivotally mounted on a pivot bearing 38 and can be pivoted by a pivot drive device 40. To securely grip the cleaning roller 28, it has a gripping claw, not shown, which grips the cleaning roller 28, which is essentially dumbbell-shaped, and transfers it in the desired manner into the working position or into the cleaning position 30.
  • the suction and / or blow hose 20 for the drafting system 24 opens into a contour nozzle 42 which engages around the drafting system rollers 44 of the drafting system 24 and in the illustrated embodiment sucks them off.
  • the contour nozzle 42 engages in the area of the drafting system 24 between two pendulum supports, not shown in FIG. 1, after the gripping arm 22 has reached there cleaning roller 28 initially located has removed.
  • the contour nozzle 42 and the suction and / or blow hose 20 are pivotally mounted on an operating arm 46, a pivot drive unit 48 making the pivot movement possible, and is also connected to the suction and / or blow unit 16.
  • both the operating arm 46 and the gripping arm 22 are shown in the pivoted-out position, it is understood that first the gripping arm 22 brings the cleaning rollers 28 into the cleaning position 30 and immediately thereafter the operating arm 46 laterally is moved past the gripper arm 22 into the pivoted-out position and sucks the drafting system 24.
  • the suction and or blowing arm 18 has a transverse guide 50, via which it can be brought into the area of the cops 52.
  • the whirlpool area can accordingly be cleaned via the suction and / or blowing arm 18, for which purpose the suction and / or blowing arm 18 has a mouthpiece 54 which engages in the area 52 and is connected to the suction and / or blowing unit 16.
  • the shift from the working position, which is shown in FIG. 1, to the retracted rest position is accomplished by a drive device 56, which is connected to the transverse guide 50 and the suction and / or blowing arm 18.
  • the suction and / or blow arm 18 also carries a whirl knife 58 in the area of the mouthpiece 54, the exact configuration of which can be seen in FIG.
  • the whirling knife 58 is mounted so that it can move essentially transversely, the front end position relative to the textile machine is determined by the abutment of the mouthpiece 54 on the textile machine, so that there is a comparatively accurate reference point.
  • the whirling knife 58 has a cutting edge 60, an arcuate region 62 and a striking plate 64 and is guided on a guide profile 66. When moving from a release position into the cutting position, the guide profile 66 simultaneously causes the cutting edge 60 to move in the lateral direction, the direction of movement corresponding to the circumferential movement of a spindle 68 which is still rotating.
  • the striking plate 64 has a dual function. It limits the movement of the whirling knife 58 in the direction of the spindle 68, a spring element 70 formed by a rubber block forming a stop for the striking plate 64 in this direction, and on the other hand serves as a stopping surface for a striking bar 72, of which the whirling knife is in the actuating direction is encountered.
  • the impact rod 72 is acted upon by a compression spring 74 with spring force in the direction of the whirling knife 58.
  • the striking rod 72 is released by a schematically illustrated triggering device, whereby the striking rod 72 is struck against the striking plate 64 by the force stored in the compression spring 74.
  • the pulse generated in this way is transferred to the whirling knife 58, which carries out the cutting process.
  • both the striking rod 72 and the whirling knife 58 are brought into the tensioned state by a return device 76, the spring element 70 assisting the rebounding of the whirling knife 58.
  • FIG 3 shows the position of the whirling knife 58 in relation to the splinter 68 in four different states I to IV which follow one another in time.
  • position I the whirling knife 58 is in a position in which the cutting edge 60 is still spaced from the spindle 68, the whirling knife 58 pointing to a point on the surface of the spindle 68 which, in the direction of rotation R of the spindle 68, lies before the point at which the whirling knife 58 touches the spindle 68.
  • the cutting edge 60 is already on the circumferential surface of the spindle 68 and is practically carried by it in the direction R into the position III, while the whirling knife 58 has moved away from the surface of the spindle 68 in the position IV, so that the cutting process is complete.
  • the cutting edge 60 of the whirling knife 58 describes approximately a semicircular movement symmetrical to the surface of the spindle 68.
  • a similar semicircular movement is also carried out by the whirling knife 58 in the direction parallel to the axis of the spindle 68.
  • the same reference numerals here as in the other figures indicate the same parts and do not require any further explanation.
  • the actual cutting process accordingly takes place between the positions II and III, the relative movement between the spindle 68 and the whirling knife 58 facilitating the cutting.
  • the configuration of the contour nozzle 42 can be seen. This engages around the drafting rollers 44 and particularly engages in the column on the side of the drafting rollers 44, which are particularly at risk of dust. It extends over the entire width between pendulum supports 78 and is connected to a high-pressure fan, which permits intensive cleaning at these points with a comparatively low air output.
  • the cleaning device according to the invention can also be combined to form a unit with a thread tying machine.
