Definitions

  • My invention relates to a suction tube for textile machines and more particularly to a suction tube of the type having an orifice formed in a smooth flat plate.
  • Suction tubes are employed for very many purposes in textile machines, for example for cleaning specific machine components, for seizing and readying yarn ends, for removing surplus or severed yarn ends by suction, and the like.
  • a suction tube with an end plate which is mounted for movement relative to the nozzle end of the suction tube for opening and closing the same.
  • Means for sealing the suction-tube orifice can be provided which functions in accordance with movement of the plate relative to the suction-tube nozzle. It is Well known that innumerable suction tubes in textile machinery are operable only for a short time and serve no operational function for a rather lengthy interval. For this reason, the suction tube orifice is provided with a sealing member which is opened only when the suction tube is in actual operation. Since the plate provided with the suction-tube orifice in accordance with my invention is mounted for movement relative to the nozzle end of a suction tube, the displacement of the plate serves for actuating the sealing means.
  • I provide a plate having a suction-tube orifice and mounted pivotably or slidably directly in front of the open end of the suction tube so that it can itself serve as the sealing means for the suction tube.
  • I provide a plate which is movable against the restoring force of a spring for example and which is provided with at least one stop member connected directly or indirectly with the suction tube.
  • the device is accordingly so constructed that the opening formed in the plate is located in front of the suction-tube orifice only in the operative position of the plate whereas in the inoperative position of the plate, the suction-tube orifice is covered by the plate. The operator thus has merely to slide the plate against the restoring or biasing force of the spring in order to bring the opening formed in the plate into alignment with the suctiontube orifice.
  • the yarn end is then laid on the plate and is immediately sucked into the tube.
  • the opening in the plate is again moved away from the suction-tube orifice and the plate then closes the suction-tube orifice.
  • a yarn length which may project out of the opening in the plate and extend to a yarn coil can be clamped between the plate and the suction-tube end.
  • FIG. 1 is a top plan view of the plate constructed in accordance with my invention showing the suction tube in dotted lines;
  • FIG. 2 is a sectional view of FIG. 1 along the line IIII taken in the direction of the arrows;
  • FIG. 3 is a sectional view of FIG. 1 along the line IIIIII taken in the direction of the arrows;
  • FIG. 4 is a schematic, partly sectional view of a textile machine in which the suction tube of my invention is incorporated.
  • a plate 51 which is provided with an opening 52 in its flat smooth face.
  • the plate 51 is movably-mounted on one end of a suction tube which is provided with an end orifice 54.
  • the plate 51 is pivotable about a pin 56 suitably supported in an eccentric arm 55 extending transversely to the longitudinal axis of'the suction tube 100.
  • the pin 56 is turnably mounted in a bore formed in the arm 55 and is secured rigidly at one end to the plate 51.
  • a torsion spring 57 abutting the arm 55 at one end and the side of the plate 51 at the other end is constrained to turn the plate 51 about the pin'56 in a counterclockwise direction.
  • This turning movement is limited by a stop member 58 consisting of a boss projecting on the inside of the plate 51 when it abuts the suction tube 100.
  • An additional stop member 59 similarly limits the turning movement of the plate 51 in opposition to the force applied by the spring 57, that is, limits the turning movement in the clockwise direction.
  • the suction-tube orifice 54 is covered by the plate 51, i.e. the opening 52 is not aligned with the suction-tube end orifice 54.
  • the plate 51 is pivoted clockwise about the pin 56 in the direction of the arrow A shown in FIG. 1, against the restoring force of the spring 57 and until the stop member 59 abuts the suction tube 100, then the opening 52 in the plate 51 reaches a position in which it is directly above the suction-tube end orifice 54 and the suction tube is accordingly opened.
  • a yarn F can consequently be sucked into the tube 100 and when the suction tube opening 54 is closed by the reset spring 57, the yarn F becomes clamped between the plate 51 and the end of the suction 3 tube 100 as shown in FIGURE 3.
  • its upper surface can be provided with suitable contours, for example one or more concave recesses 62, which can be readily gripped by the operators fingers.
  • FIG. 4 A particularly advantageous application of the device constructed in accordance with my invention is illustrated in FIG. 4.
  • a textile machine having a plurality of reserve yarn coils such as spinning cops suitably located in a magazine, the yarn ends of the coils being held ready within a suction tube.
  • the structure and operating principles of such an appartus are described -in Patent No. 3,059,867, issued on October 23, 1962 and in the copending application Serial No. 355,585 of Stefan Furst filed on March 30, 1964.
  • a yarn guiding drum 2 is carried on a shaft 1 and is in engagement with a take-up spool 4 journalled on a carrier frame 3.
  • the take-up spool 4 is frictionally driven by the yarn guiding drum 2.
  • the yarn F is accordingly unwound from the supply coil or cop 5 and wound up on the take-up spool 4.
  • Two yarn seeking suction tubes or arms 6 and 10 feed the yarn ends to a knotting device 9 when a yarn break occurs betweenthe tensioner 19 and the take-up spool 4.
  • An additional yarn seeking arm 11 feeds the yarn from a supply coil 5 into the vicinity of the yarn seeking suction tube 10 which accordingly delivers it to the knotting device when the supply coil is to be replaced.
  • a circular magazine 20 for supply cops which is coaxially mounted on a suction tube 100.
  • the supply coils are contained in shells or compartments which in turn are mounted for rotation about the suction tube and are rotated through one sector or division by well known and conventional stepping devices, such as a ratchet and pawl assembly, whenever the supply coil is replaced.
  • an opening 204 is provided which is usually closed by a lid 205.
  • the lid 205 is at one end of a centrally pivoted rocker arm whose other end is pivoted at one end of an elongated rod 207.
  • the other end of the rod 207 is pivotably connected to one end of a centrally pivoted double arm lever 206.
  • a chute 202 is located beneath the opening 204 of the supply-coil magazine 20, the respective supply coil being able to slide down the chute 202 onto the pivoted supply coil mandrel 5a when the lid 205 is opened.
  • FIGS. 1 to 3 there is shown in enlarged view the device constructed in accordance with my invention mounted on a suction tube 100.
  • the plate 51 which closes the end of the suction tube 100 can be opened in relation to the textile machine cycle instead of by hand.
  • a swivel arm 60 is provided which is pivotable about the pin 56 and, as shown in FIG. 1 by the broken lines, is actuated by the rod 108 which is in turn connected in any suitable manner known to the man of skill in the art to the textile machine to provide the desired motion.
  • the rod 108 As shown in FIG.
  • the part of the rod 108 which extends alongside of the suction tube 100' is mounted in elongated slots in the bearing 61 which is secured to the suction tube 100.
  • the rod 108 is controlled by the cam 111 engaged by one end 110 of a centrally pivoted double lever 109 whose other end is pivotably connected to the free end of the rod 108.
  • the plate 51 is cup-shaped so that it covers the cooperating components 55, 56, 57, 60 which actuate its movement at the top and at the sides, as seen particularly in FIG. 2, so that no yarn lengths can be accidentally caught therein.
  • yarn at this stage extends slidingly through a slot 20a of the supply-coil magazine from the suction tube to the head of the coil.
  • Control means that are not illustrated but that are well known from Patent No. 3,059,867, for example, then cause the arm 11 to pivot to the position shown in phantom in FIG. 4. Since the arm 10 is pivoted downwardly in the meantime to the phantom position also shown in FIG. 4, the yarn that is carried upwardly by the arm 11 can then be grasped by the suction nozzle of the suction arm 10 and delivered to the knotting device 9. The yarn end of the takeup spool 4 is simultaneously conveyed by the suction arm 6 to the knotting device 9 so that both yarn ends can be knotted together.
  • the yarn extending from the knotting .device to the opening of the suction tube 100 is severed by unillustrated means such as are disclosed in the aforementioned Patent No. 3,059,867.
  • the plate 51 is simultaneously pivoted by the cam 111 through the linkages consisting of the double arm lever 109, and the rod 108 and the pivot arm 60, because shortly before the end of the supply-coil replacement operation, that is, shortly before the dwell position of the cam 111 shown in FIG.
  • the double lever 109, 110 is pivoted by the cam lobe 111a counterclockwise
  • the end orifice of the suction tube 100 is thereby opened and the severed yarn end that was clamped therein is freed so that it can be sucked into the suction tube 100.
  • the opening of the suction tube 100 for a short period each time after a supply-coil replacement permits the yarn with the coils 5', 5" to travel around the suction tube 100 and to take a suitable position when the supply coil is replaced in a manner described in the aforementioned copen-ding application Serial No. 355,585 of Stefan Furst filed on March 30, 1964.
  • the starting end of the yarn of the reserve supply coils 5' and 5" can be easily fed into the end orifice of the suction tube 100 without any danger arising of possibly entangling the yarn length leading to the reserve or supply coil about any projecting portions or edges thereof. It is also within the scope of my invention to employ instead of a circular magazine as is illustrated in FIG. 4 also a straight-line magazine as is for example shown and described in the aforementioned Patent 3,059,867.
