  • the body 1 of a spinning unit has built therein a feed roller 2, a combing roller 3, a yarn breakage sensing feeler 4, and a solenoid clutch 5 for controlling the feed roller by an actuation of said feeler 4, and there is disposed a rotor cap 7 opposed to the opening side of a rotary spinning chamber 6.
  • the spinning chamber 6 is held for rotation within a casing 8 that is pivotally mounted to the spinning unit body 1 by a pin 9 and connected to said body 1 by a hook 10.
  • a sliver S fed to the spinning unit is delivered to the combing roller 3 by the rotation of the feed roller 2, combed by the combing roller, separated from the peripheral surface of the combing roller 3 by means of air currents, conveyed via a feed channel 11 to the rotary spinning chamber 6 where the separated fibers are gathered together and then continuously withdrawn through a yarn drawing tube 12 by a pair of drawing rollers 13 to form a spun yarn Y.
  • the yarn breakage sensing feeler 4 Disposed between the outlet from the yarn drawing tube 12 and the drawing rollers 13 is the yarn breakage sensing feeler 4, which, when a yarn break occurs in a spinning chamber 6, actuates a lead switch (not shown) to actuate the solenoid clutch 5 to disengage the clutch portion 5', thereby stopping the rotation of the feed roller 2 to interrupt the feeding of the sliver S.
  • such spinning unit 1 houses a suction tube 15 and a blow tube 16, said tubes having one of the respective ends extending through the rotor cap 7 and opening to the spinning chamber 6 and the other ends connected to valve means 14, and the spinning unit body 1 is arranged to be tiltable around the axis of a pivot 17 in the lower region thereof through a predetermined angle of inclination.
  • the cylindrical body 19 is provided with suction and blow passageways 26 and 27 out of phase with each other for establishing communication between said openings 20 and 23 and between said openings 21 and 25, respectively.
  • said cylindrical body 19 is provided with a shaft 28 to which an arm 29 having a pin 30 at the front end thereof is secured and said pin 30 is fitted in a slot 32 in a stationary guide plate 31 so that when the spinning unit body 1 is tilted along with the valve means 14, the pin 30 of said arm 29 is controlled by the guide plate 31, whereby the cylindrical body 19 is rotated within the box 18 to displace the passageways 26 and 27.
  • a resilient brake 34 secured to the frame 33 of the spinning machine. Said brake 34 is rotatable around the axis of a pivot 35 and resiliently loaded by a coiled spring 36 which gives a reaction substantially balancing with a moment resulting from the weight of the spinning unit body 1 upon tilting thereof.
  • the pulley 37 of the rotary spinning chamber 6 is moved out of contact with a driving belt 38 into abutment against the shoe 34 of said brake 34 so that the rotation of the spinning chamber 6 and the tilting of the spinning unit body 1 are stopped.
  • reaction of the coiled spring 36 balances with or overcomes the rotational moment resulting from the weight of the spinning unit body 1
  • the spinning unit body 1 is maintained in a supported state by the reaction of said spring 36. This means that the spinning unit body 1 is ready for being further tilted through a predetermined angle of inclination if it is manually urged against the action of the spring 36.
  • valve means 14 has been displaced as a result of said tilting movement into a position where the blow passageway 27 establishes communication between the openings 21 and 25, as shown in FIG. 10, whereby compressed air from the tube 24 connected to the compressed air source is fed to the blow tube 16.
  • the suction passageway 26 also is displaced, but it is so arranged that it continues to maintain communication between the openings 20 and 23 (see FIG. 3). That is, the relative position of the two passageways 26 and 27 or their diameters are designed with due considration given to the range of rotation of the cylindrical body 19 attendant on the tilting of the spinning unit body 1.
  • the yarn breakage sensing feeler 4 When a yarn breakage occurs in the spinning state shown in FIGS. 1 and 2, the yarn breakage sensing feeler 4 is first tilted whereby a lead switch (not shown) is closed to energize the electric circuit to actuate the solenoid clutch 5 of the feed roller 2 through a relay for stopping the feed roller 2 and to energize a yarn breakage indicating lamp 39.
  • the worker walks to the front of the spinning unit in question where the yarn break has occurred, and he carries out the mending of the broken yarn. Prior to effecting the mending of the broken yarn, he pushes a push-button for disengaging a locking member (not shown) which locks the spinning unit body 1 in its spinning position.
  • said tilting of the spinning unit body 1 actuates the arm 29 to rotate and displace the cylindrical body 19 of the valve means 14 so as to align the suction passageway 26 with the upper and lower openings 20 and 23 in the box 18 to establish communication between the two openings 20 and 23, as shown in FIG. 8, so that the suction force from the suction source (not shown) is admitted into the suction tube 15 to apply suction to the spinning chamber 6 through the open end of said suction tube 15.
  • the suction force from the suction source (not shown) is admitted into the suction tube 15 to apply suction to the spinning chamber 6 through the open end of said suction tube 15.
  • the valve means 14 may be divided into two parts, a suction valve and blow valve, so that the suction valve is first opened automatically in connection with the first stage tilting of the spinning unit body under its own weight, as described above, to impart a sucking action to the spinning chamber 6 and the blow valve is then manually opened to blow compressed air into the spinning chamber 6 without imparting a second stage tilting movement to the spinning unit body 1.
  • the brake may be of the fixed type and it is not necessary to support it by the spring 36 to make it movable.
  • a ringless spinning machine comprising spinning units each having a feed roller 2, a combing roller 3 and a spinning chamber 6 and adapted to control the feed roller 2 by the actuation of a yarn breakage sensing feeler 4, the present invention provides a method of cleaning the spinning chambers comprising, upon yarn breakage, tilting a spinning unit body 1, which supports its associated spinning chamber 6, to stop the rotation of the latter, applying first a sucking action to the interior of the spinning chamber 6 to discharge the residual fibers and then blowing compressed air into said spinning chamber 6 to remove the residual material adhering to the inner wall surface of the spinning chamber 6.
  • the material remaining in the spinning chamber upon yarn breakage can be reliably and quickly removed.
  • the present invention provides an apparatus for carrying out said method, comprising means for tilting a spinning unit body 1 supporting its associated spinning chamber 6, a brake 34 disposed above a spinning machine frame 33 and resiliently supported by a spring 36, said spinning unit body 1 housing a suction tube 15 and a blow tube 16, one of the respective ends of said tubes opening to the spinning chamber 6, and valve means at the other ends of said tubes whereby when the spinning unit body 1 is tilted to bring the pulley 37 of the spinning chamber 6 into abutment against said brake 34, communication is established between a suction source and said suction tube 15 and when the spinning unit body 1 is further tilted against the action of said spring 36 of the brake 34, communication is established between a blow source and a blow tube 16.
  • FIGS. 11 15 Next, another embodiment shown in FIGS. 11 15 will now be described.
  • the blow groove 41 of the blow tube 16in the preceding embodiment is arranged substantially in the direction of and along with the feed channel 11 and a small amount of air is constantly blown from said blow groove 41 during the spinning operation to control the direction of flow of fibers fed in from the feed channel 11.
  • a sucking action is first applied to a suction tube 15 and then the amount of air fed by the blow tube 16 is increased to carry out thevcleaning of the spinning chamber 6 in the manner described in connection withthe preceding embodiment.
  • a suction tube 15 in the spinning unit body 1 the front end of which opens to the spinning chamber and the terminal end of which communicates with a suction source 44 through a switching valve 43
  • a blow tube 16 in the spinning unit body 1 having an outlet end groove 41 arranged substantially in the direction of and along with the feed channel 1 l and opening to the rear of the outlet from the feed channel and an inlet end which communicates with a compressed air source 46 through a two-stage flow control changeover valve 45.
  • the reference numeral 47 designates a brake member associated with the pulley 37 of the spinning chamber 6, the arrangement being such that when the spinning unit body 1 is tilted, the pulley 37 of the spinning chamber 6 which is displaced therewith abuts against said brake member 47 to stop the rotation of the spinning chamber 6.
  • the numeral 48 designates a locking member for locking the spinning unit body 1 and the frame 33 together. Said locking member has a hook portion 49 urged toward the frame 33 by a spring 50, and a stem 48 opposed to an electromagnet 52 adapted to be energized by an actuation of a yarn breakage sensing feeler 4.
  • the numeral 53 designates a solenoid for restoring the tilted spinning unit body 1 to its normal position, said solenoid being adapted to be energized by an action of a timer (not shown) only at the time of returning of said body 1 upon lapse of a predetermined period of time after said body 1 is tilted.
  • the yarn breakage sensing feeler 4 first senses it whereby a lead switch (not shown) is closed to energize an electrical control circuit (not shown) to actuate the solenoid clutch 5 through a relay to stop the feed roller 2.
  • the electromagnet 52 is energized to attract the stem 51 of the locking member 48 against the action of the spring 50, thereby releasing the hook 49.
  • the spinning unit body 1 is outwardly tilted under its own weight around the axis of a pivot 17 through predetermined angle of inclination until it is stopped by the action of a latch 54.
  • This tilting displaces the spinning chamber 6 so that the pulley 37 of said spinning chamber 6 is moved out of contact with a driving belt 38 into abutment against the brake member 47 whereby it is stopped.
  • the switching valve 43 is opened to impart a sucking action to the suction tube to suck and remove the fibers remaining in the spinning chamber 6 through the front end opening 42.
  • the flow control changeover valve 45 is changed over to an intense flow so that a larger amount of compressed air is blown into the spinning chamber 6 to scatter the remaining material adhering to the inner wall surface of the spinning chamber 6, said material being then removed through the suction tube 15.
  • the switching valve 43 for the suction tube 15 remains closed during the spinning operation shown in FIG. 11. And a small amount of compressed air is blown from behind the outlet 11' from the feed channel 11 in the direction of feed of the fibers (see FIG. 13). This flow of air is effective to quickly move all of the fibers, delivered from the outlet 1 1 of the feed channel, toward the wall surface of the spinning chamber 6, and to make up for a decrease in the rate of flow of fibers in a space behind the separator 40 and thus prevent the stagnation phenomenon of fibers, thereby ensuring favorable conditions for spinning.
  • the tilting of the spinning unit body 1 causes the switching valve 43 to open to pass a sucking action to the spinning chamber 6 at rest to remove the fibers remaining therein. Subsequently, the flow control changeover valve 45 is changed over from weak to intense flow so that the amount of air being fed from the compressed air source is increased to pass an intense flow of compressed air to the spinning chamber 6 to scatter the impurities adhered to the inner wall surface of the spinning chamber, which are then discharged through the suction tube 15.
  • the solenoid 53 is actuated to' bring the spinning unit body 1 back to the original position and at the same time the electromagnet 52 is deenergized to permit the hook 49 to lock said body 1 to the frame 33 and the switching valve 43 is closed while the changeover valve 45 is turned to weak flow. In this way the cleaning of the spinning chamber 6 is automatically completed.
  • the body 1 is tilted to stop the spinning chamber, whereupon sucking action is first applied to the spinning chamber at rest to remove the residual fibers and then compressed air is blown thereinto to scatter the impurities adhering to the inner wall surface of the spinning chamber 6, which are then sucked and discharged.
  • sucking action is first applied to the spinning chamber at rest to remove the residual fibers and then compressed air is blown thereinto to scatter the impurities adhering to the inner wall surface of the spinning chamber 6, which are then sucked and discharged.
