Definitions

  • the invention relates to a drafting system in a textile machine, with a drivable outlet cylinder which is fixedly mounted in a machine frame, and with a drivable inlet cylinder and at least one drivable intermediate cylinder, each of which carries a drive wheel and is mounted in a frame which is in the machine frame is adjustable relative to the outlet cylinder and can be fixed with releasable locking elements, at least one drive belt, against which a tensioning roller rests, being placed around at least one of the drive wheels and around a drivable wheel.
  • the intermediate cylinder immediately adjacent to the outlet cylinder is approximately radially adjustable with respect to the outlet cylinder with the frame in which it is mounted, so that the distance between the clamping line on this intermediate cylinder and the clamping line on the outlet cylinder is optimally adjusted to match the stack of the fiber material to be warped can be.
  • the drivable wheel is mounted in the adjustable frame and is in turn driven by a motor mounted in the machine frame via a toothed belt.
  • the effect of adjustments of the frame on the toothed belt is to be compensated for by a spring-loaded tensioning roller resting against it.
  • the inlet cylinder and the intermediate cylinder are driven by gears from a shaft mounted in the machine frame. Since the adjustability of these cylinders and the frame must be ensured, the gearwheels used for this purpose are complicated and expensive.
  • the object of the invention is to provide the means for driving the inlet cylinder and the intermediate cylinder in a drafting system of the type specified at the outset or to make the intermediate cylinder simpler and cheaper in comparison with known drafting systems.
  • the object is achieved according to the invention in that the drivable wheel is mounted in the machine frame, that the tensioning roller for the drive belt is mounted on a movable carrier and that one of the locking elements is set up to move the frame, the movable carrier and the machine frame in relation to one another fix.
  • said locking element which fixes the frame, the movable support and the machine frame with respect to each other, the risk of overstretching the drive belt and / or damage to the bearings of the cylinders when adjusting the frame is excluded, because such adjustment is only possible after this locking element has been released and thus the carrier of the tensioning pulley has been released so that the tensioning pulley can move freely.
  • the drive belt is preferably a toothed belt. However, it could also be a chain or a flat belt, for example.
  • the drive wheels of the cylinders and the drivable wheel mounted in the machine frame would of course have to be adapted accordingly.
  • the drawing system shown schematically contains a drivable outlet cylinder 1, which is mounted in a machine frame 2 of a textile machine, in particular a combing machine.
  • An outlet pressure roller 3 interacts with the outlet cylinder 1 and is pressed downward against the outlet cylinder during operation by loading means (not shown).
  • the drafting system also contains an inlet cylinder 4 and three intermediate cylinders 5, 6 and 7, all of which are rotatably mounted in a frame with two side plates 8 and 9.
  • the frame 8, 9 is displaceable in the machine frame 2 with respect to the outlet cylinder 1, for example with the aid of an adjusting screw 10 which extends through a bore in part 2.1 of the machine frame 2 and is screwed into a threaded bore in a crossbar 11 of the frame 8, 9 .
  • two locking elements are arranged, with which the frame can be fixed in any set position with respect to the machine frame 2.
  • the locking elements have, for example, the shape of clamping screws 12 and 13 or 14 and 15, which extend through elongated holes 16, 17, 18, 19 in the frame side plates 8 and 9 and are screwed into threaded bores in the machine frame 2 (FIGS. 3, 4) .
  • the frame 8 9 there are also two pressure rollers 20 and 21 (FIGS. 1, 2) which are pressed down during operation by means of loading devices, not shown, against the intermediate cylinders 4 and 5 or against the intermediate cylinders 6 and 7.
  • a drive belt in the form of a toothed belt 22 runs on the outside of the frame side plate 8 around drive toothed wheels 23 and 24, which are supported by the intermediate cylinders 6 and 7, and around a toothed wheel 25, which is seated on a drivable shaft 26 mounted in the machine frame 2.
  • a tension roller 27 is in contact with the toothed belt 22.
  • This is rotatably mounted on a carrier 28 which is pivotally mounted on the machine frame 2 about an axis 29.
  • the clamping screw 13 extends not only through the elongated hole 17 in the frame side plate 8, but also through an elongated hole 30 in the carrier 28. Thus, the clamping screw 13 serves to pivot the carrier 28, the displaceable frame side plate 8 and the machine frame 2 with respect to one another fix.
  • a second toothed belt 32 runs on the outside of the frame side plate 9 around drive toothed wheels 33 and 34, which are carried by the intermediate cylinders 4 and 5, and around a toothed wheel 35, which is also seated on the drivable shaft 26.
  • a tensioning roller 37 is in contact with the toothed belt 32.
  • This is rotatably mounted on a carrier 38 which is pivotally mounted on the frame side plate 9 about an axis 39.
  • the clamping screw 15 extends not only through the elongated hole 19 in the frame side plate 9, but also through an elongated hole 40 in the carrier 38.
  • the clamping screws 12, 13, 14 and 15 must first be loosened. This also releases the carriers 28 and 38 of the tensioning rollers 27 and 37.
  • the tensioning rollers 27 and 37 since they are mounted on the freely pivotable supports 28 and 38, cannot cause excessive tension in the toothed belts 22 and 32.
