Definitions

  • the present invention relates to a ring spinning or twisting machine according to the preamble of claim 1.
  • the fixing sleeve serves to fix the thread on the machine side on the spindle shaft, which allows the freshly spun bobbin to be doffed:
  • a spinning process, during which a cop is built, is completed by the spinning phase.
  • the upper, rear and underwinding are carried out during spinning.
  • the underwinding arises as soon as the thread is guided beyond the underwind crown to the underlying spindle shaft section, which presupposes that the fixing sleeve is in the open position. Otherwise the underwinding would be applied to the fixing sleeve.
  • the fixing sleeve must take up its working position, which means that by pressing the thread against the underside of the underwind crown, it fixes the thread section lying in the underwinding and thus the thread at all. If the cop is removed during the subsequent doffing, the thread defined in the underwinding tears at the underwind crown. A new cop can now be freshly spun on; the thread still has to be fixed. As soon as the cop is filled, the cycle starts again.
  • EPA 0 292 852 now shows a spinning unit for a ring spinning machine, the spindle shaft of which is provided with an underwind crown, and a fixing sleeve which is axially displaceable on the shaft relative to the underwind crown.
  • the thread is fixed in a position of the fixing sleeve striking the underwind crown, while in in a position distant from the underwind crown, the thread can be placed in or removed from the underwinding.
  • the fixing sleeve is in its lower, i.e. part removed from the underwind crown in such a way that it can expand during the rotation of the spindle shaft by the then prevailing centrifugal force.
  • the expandable part engages in an essentially rotationally symmetrical control element for the fixing sleeve which is stuck on the spindle shaft.
  • the expandable part of the fixing sleeve and the area of the control member which is in engagement with it are mutually designed such that the fixing sleeve must move downward, due to the rotation-related spreading, into its open position, while moving through the reshaping given when the spindle shaft is at a standstill pushes upwards in the closing, ie working position.
  • the ring spinning or twisting machine according to the invention has the characterizing features of claim 1.
  • the ring frame carries out the necessary movements for piecing, spinning and spinning. In particular when spinning it takes up a position above and when spinning, or when applying the underwinding, a position below the underwind crown. This means that the position of the ring frame provides clear information regarding the necessary position of the fixing sleeve: If the ring bench lowers in the downwind position, the fixing sleeve must be kept in the open position for the application of the winding. In the other positions of the ring frame, the fixing sleeve must be kept closed, which ensures that the thread remains fixed during the piecing.
  • a preferred embodiment according to claim 6 provides that the ring frame acts via an effective section on a stop surface of the fixing sleeve and thus presses the fixing sleeve for the winding in the open position. In addition to the task at hand, this ensures that the fixing sleeve is driven and controlled by an extremely simple and robust construction can be realized, so that a separate drive for the fixing sleeve and complex control are eliminated.
  • the figure shows a spinning unit 1, a frame 2, a ring frame 3 and a spindle shaft 4 with a whorl 5 of a ring spinning or twisting machine.
  • a spinning unit 1 a frame 2, a ring frame 3 and a spindle shaft 4 with a whorl 5 of a ring spinning or twisting machine.
  • the areas of the spindle shaft bearing and the bearing of the ring frame 3 provided in the frame 2 are omitted.
  • the figure further shows a circumferential shoulder 7 at the upper end of the spindle shaft 4, on which a sleeve 8 of a cop 9 is placed. Underneath the sleeve 8 there is an underwind crown 10 which is fixedly arranged on the spindle shaft 4 and, under this in turn, a fixing sleeve 11.
  • the whorl 5 has a cambered surface 12 for a spindle shaft drive belt 13 and a spindle shaft holder 14 which surrounds the base of the spindle shaft 4 in a tubular shape.
  • the fixing sleeve 11 is held axially displaceably on the spindle shaft holder 14 of the whorl 5 with respect to the spindle shaft 4. It is also supported on the spindle shaft 4 by a flange 15 projecting towards the inside. The flange 15 also limits the range of displacement of the fixing sleeve 11 by in whose uppermost position abuts against the underwind crown 10 via a fastening surface 16 and strikes against the spindle shaft holder 14 in its lowest position via a stop surface 17.
  • a driver part 18 of the sleeve 11 projecting radially at least in the direction of the ring frame 3 radially from the fixing sleeve 10 has a stop surface 19, via which the driver part 18 and thus the sleeve 11 itself can be acted on.
  • the ring frame 3 is mounted on the frame 2 so as to be vertically movable and can be moved back and forth between an upper end position above the upper edge of the sleeve 8 and a lower end position below the underwind crown 10. It carries a spinning ring 25 with a rotor 26 at the location of the spinning units assigned to it. Furthermore, an active section designed as a rocker arm 27 is formed on the ring frame 3, which is in a non-positive connection with the stop surface 19 of the driving part 18, thus a mechanical coupling of the ring frame 3 trained with the fixing sleeve 10. The direction of action of this coupling runs parallel to the longitudinal axis of the spindle shaft 4 against the whorl 5, ie towards the bottom.
  • a spring 30 is clamped between the shoulder section 15 of the fixing sleeve 10 and the spindle shaft holder 14 in such a way that it exerts a force on the fixing sleeve against the direction of action of the coupling or non-positive connection between the ring frame 3 and the sleeve 10.
  • the ring frame 3 lowers from its upper end position against the underwind crown 10, as a result of which the rear winding is formed on the freshly filled cop 9.
  • the rocker arm 27 pushes against the stop surface 19 of the driver part 18, with the consequence that the fixing sleeve is pressed against the pressure of the spring 30 from its working or closed position into the open position. It thus follows that the fixing sleeve 10 is already in an open position as soon as the rotor reaches the area below the underwind crown 11, which ensures that the underwinding can be created without problems, in particular independently of the spindle shaft speed.
  • the ring frame 3 lifts again, whereupon the thread from the underwinding runs back up through the underwinding beads.
  • the fixing sleeve (11) is brought into the working position by the pressure of the spring 30, so that the thread section lying in the underwinding is clamped between the fixing surface 16 and the underwind crown 11 for doffing.
  • the ring frame acts in two opposite directions of action on the fixing sleeve, so that a spring 30 is omitted. This results in a forced control of the fixing sleeve by the ring frame.
