Definitions

  • the invention relates to a take-off device for flat knitting machines, with a goods take-up roller which is divided into a plurality of coaxial partial rollers and cooperates with a counter-pressure roller, each partial roller rotatably mounted in one direction on the common axis being separately drivable via an adjustable clutch and being driven by a rotating cam star as a drive element
  • Actuatable spring-loaded pivot lever is assigned, which is connected to the partial roller in a rotationally fixed manner in the take-off direction via a wrap spring clutch arranged within the partial roller.
  • a trigger device of the type mentioned has been proposed in DE-PS 32 17 395.
  • the pretension of the spring loading the pivoting lever of a partial roller can be set to different values by hand on the take-off device itself be put.
  • this setting is only possible before the machine is started up. It is not possible to change the preload while the machine is in operation.
  • the invention is based on the object of designing the draw-off device mentioned at the outset in such a way that the pretensioning of each partial roller can also be set during operation of the flat knitting machine.
  • an electrically operated and controlled adjusting element can be used here, in particular an electric motor, with which a support or holding part for the spring can be adjusted.
  • the electric motor can be connected to a threaded shaft on which a screw nut part which is coupled to the support or holding part for the spring is arranged in a rotationally fixed manner.
  • low-power small regulating or control motors are sufficient, which are only supplied with current for adjustment, and therefore are not permanently loaded by current.
  • the adjustment distance of the adjustment element can be chosen to be so large that complete relaxation of the loading spring and thus practically also stopping of the associated partial roller can be achieved.
  • FIG. 1 shows the two needle beds 10 and 11 of a flat knitting machine and a knitted web 12 made on this flat knitting machine, which extends downward from the comb gap 13 of the machine to a take-off roller 14 and is further discharged downwards via a counter roller 15. Its axis 16 and one of its partial rollers 14.x can be seen from the take-off roller 14.
  • the drive device for the goods take-off roller 14 consists of a common drive shaft 17 which, for each partial roller 14.x, has a star from cams 18 formed here by inserted pins 18, which act on an associated pivot lever 19.x mounted on the axis 16, with which one the associated partial roller 14.x can be tensioned in the pull-off direction by the compression spring 20.x via the swivel lever 19.x.
  • the compression spring 20.x is indirectly coupled to the swivel lever 19.x with its upper end in the drawing, while its lower end in the drawing is supported on a support wall 21.
  • each partial roller 14.x is assigned its own and with which the bias of the compression spring 20.x, which is exerted by the partial roller 14.x on the knitted web 12
  • Goods take-off torque that is to say the goods take-off force exerted on the knitted web 12 on the partial roller 14.x, can be changed.
  • the support wall 21 is formed at one end of a hollow body 43 which is guided between two walls 41 and 42 and is provided with a screw nut part 44 in its other end.
  • An electric motor 45 preferably a stepper motor, is attached to the two walls 41 and 42 and has a threaded shaft 46.
  • the threaded shaft 46 cooperates with the screw nut part 44, so that when the threaded shaft 46 rotates in one direction or the other, the hollow body 43 with the support wall 21 is moved up or down in the drawing.
  • the bias of the compression spring 20.x is changed.
  • the hollow body 43 and the threaded shaft 46 are designed with sufficient length so that there is a large adjustment path for the support wall 21 which is so large that the compression spring is completely relaxed in the position of the adjustment device 40.x shown in the drawing and therefore no pull-off torque of the partial roller 14.x can cause.
  • each swivel lever is on its free end with a widened stop surface 37 for the pins 18 of the cam stars 18 'of the drive shaft 17 and is connected at its other end via screws 26 to a sleeve 27 which is freely rotatably mounted on the axis 16 which is normally held rigidly.
  • each pivot lever is connected to a ring shield 28 which is concentric with the axis 16 and with which the gap 29 existing between each partial roller 14.1... 14.x is covered on the inside in order to prevent threads from being drawn into this gap.
  • Each sub-roller 14.x is firmly connected by screws 30 to an inner foot ring 31 which is freely rotatably mounted on the concentric sleeve 27.
  • an inner foot ring 31 which is freely rotatably mounted on the concentric sleeve 27.
  • Each partial roller 14.x is with its foot ring 31 on the one hand via a right-handed wrap spring 35, which extends partly over the foot ring 31 and partly over the sleeve 27, with the sleeve 27 and on the other hand via a left-hand wrap spring 36, which extends partly over the foot ring 31 and partially extends over the coupling ring 32, with the clutch tion ring 32 coupled.
  • the wrap springs 35, 36 act in a known manner as one-way clutches.
  • the right-hand wrap spring 35 causes the associated partial roller 14.1 ... 14.x not to be moved in the counterclockwise direction during the adjustment movement of the pivot levers 19.1 ... 19.x caused by the bone stars 17, while the return movement of the pivot lever 19.1 .. 19.x clockwise under the influence of the prestressed compression spring 20.x, the right-hand wrap spring 35 causes the associated partial roller 14.x to move along.
