Definitions

  • the invention relates to a goods take-off device on flat knitting machines, with a driven goods take-off roller consisting of a plurality of roller elements and with the pressure elements of a material pressure roller assigned to the roller elements, which are seated on a common swivel shaft and can be pressed resiliently against the respective roller element.
  • a similar goods take-off device in which, however, the goods take-off roller is made in one piece, is known from DE-C-651 296. A drive of the one-piece goods take-off roller cannot be seen there.
  • the most frequently used goods take-off devices on flat knitting machines generally have a goods take-off roller and a goods pressure roller.
  • the knitted fabric which comes from the needles between the two rollers, is pulled by a driven goods take-off roller.
  • the material pressure roller has the task of pressing the knitted fabric onto the fabric take-off roller and of determining the wrap angle through which the fabric knits around the fabric take-off roller.
  • the take-off roller as is known for example from DE-PS 33 31 052, consists of a number of short roller elements corresponding to the width of the needle space, which independently of one another influence the knitted pull-off force in a spring-loaded manner over a certain angle of rotation.
  • the goods pressure roller in turn has pressure rollers which can be pressed resiliently against the respective roller elements.
  • the pressure rollers In order to obtain a uniform knitted fabric pull-off, the pressure rollers have to be adjusted more or less differently in terms of their pressure force.
  • the adjustment depends on the yarn to be processed and the binding of the knitted fabric that is to be pulled off. If the pinch rollers are adjusted so that the knitted fabric is pulled off evenly, the rows of stitches leaving the goods take-off device horizontally without a bow, and then the total pressure force has to be changed evenly, all pinch rollers must be adjusted in parallel and readjusted.
  • the invention has for its object to provide a goods take-off device of the type described in the introduction with which an automatically adjustable, reproducibly uniform knitted fabric take-off is obtained.
  • the axis of rotation of the swivel roller can be adjusted horizontally and vertically by an electric motor parallel to two coordinate axes parallel to the central axis of the goods take-off roller or can be pivoted on an arc around the central axis of the goods take-off roller. This allows the wrap angle ⁇ , which the knitted fabric passes through the material take-off roller, to be adjusted automatically in accordance with the take-off conditions.
  • the pressure rollers are advantageously each individually drivable by an electric motor.
  • an electric motor axially arranged on the pivot shaft is expediently provided.
  • a stepping motor acting on one compression spring each is advantageously provided for adjusting the contact pressure of the pressure rollers.
  • An electric motor connected to the swivel shaft is expediently provided for parallel adjustment or swiveling of the swivel shaft relative to the goods take-off roller.
  • individual stepping motors are advantageously provided for driving the pressure rollers.
  • the electric motor for swiveling in and out, the stepper motor for adjusting the contact pressure, the electric motor for parallel adjustment or swiveling and / or the stepper motors for driving the pressure rollers can advantageously be controlled via a machine control of the flat knitting machine.
  • the goods take-off device shown in FIGS. 1 and 2 has a goods take-off roller 2 consisting of several roller elements and a goods pressure roller consisting of several change pressure rollers 3.
  • a knitted fabric 1, coming between the two rollers coming from the needles (not shown), is drawn off from the driven goods take-off roller 2.
  • the pressure rollers 3 of the fabric pressure roller have the task of pressing the knitted fabric 1 against the fabric take-off roller 2 and the Wrap angle ⁇ that the knitted fabric 1 passes through the goods take-off roller 2.
  • the take-off roller 2 consists of a number of short roller elements which correspond to the width of the needle space and which, independently of one another, have a spring-loaded effect on the fabric pull-off force in a different manner via a certain angle of rotation.
  • a pressure roller 3 of the goods pressure roller is assigned to each roller element.
  • the pressure rollers 3 are mounted on a rotatable and lockable pivot shaft 5 provided with a locking lever or handle 4 so that they face the roller elements of the goods take-off roller 2 exactly.
  • Bearings 6 of the pressure rollers 3 are firmly connected to the pivot shaft 5.
  • Each pressure roller 3 is spring-loaded adjustable by means of a compression spring 7 and a grip screw 8.
  • One position is the pivoted-out position shown in FIG. 2, in which the pressure rollers 3 do not rest against the goods take-off roller 2.
  • the other position is the position shown in FIG. 1, in which the pressure rollers 3 bear against the goods take-off roller 2 and are held in this position in a latched manner.
  • the pressure rollers 3 In order to obtain a uniform knitted pull-off when knitting, the pressure rollers 3 must be adjusted more or less differently in terms of their pressure force. The adjustment depends on the yarn to be processed and the binding of the knitted fabric that is to be pulled off. The pressure rollers 3 are set so that the knitted fabric 1 is pulled off evenly. This is great recognizable in the case of colored rings, the rows of stitches having to leave the goods take-off device horizontally without a sheet. If the total pressure force is then to be changed evenly, then all pressure rollers 3 must be adjusted in parallel and readjusted.
  • the pressure rollers 3 are swiveled out and in using the handle 4, which is pinned on the swivel shaft 5, and carried out by hand.
  • Fig. 3 shows a goods take-off device, which is designed to achieve an automatically adjustable, reproducibly uniform knitted fabric such that the pressure rollers 3 can be pivoted together into variable end positions and pivoted out of these and the contact pressure of each pressure roller 3 is individually adjustable by an electric motor.
  • the pressure rollers 3 can be pivoted together by electric motors into variable pivoted end positions, as shown in FIG. 3, so that the basic position of differently adjusted pressure rollers 3 on the knitted fabric 1 can be changed accordingly.
  • the pressure rollers 3 are also pivoted out together via the electric motor 9.
  • a stepping motor 11 which works on a compression spring 7 of each individual pressure roller 3, is provided, by the action of which the contact pressure of the pressure rollers 3 is individually adjustable.
  • An electric motor 13 connected to the pivot shaft 5 makes it possible to adjust the axis of rotation 10 of the pivot shaft 5 relative to the central axis 14 of the goods take-off roller 2 either horizontally and vertically in parallel in two coordinate axes (double arrows A), or to pivot the pivot shaft 5 by motor on a circular arc around the central axis 14 of the goods take-off roller 2 ( Double arrows B). This allows the wrap angle ⁇ to be adjusted automatically and by motor in a manner adapted to the trigger conditions.
  • a single stepping motor 12 can be provided with each of the pressure rollers 3 for driving the pressure rollers 3.
  • the electric motor 9, the stepping motor 11, the electric motor 13 and / or the stepping motors 12 can advantageously be controlled via a machine control (not shown) of the flat knitting machine.
