Definitions

  • the invention relates to a ring spinning machine with drafting, the drafting rollers are mounted in punches and which downstream compression devices, each having a lower roller, a pressed against the lower roller upper roller and a flexible compression straps, which wraps around a suction under suction suction shoe and one of the rollers wherein the compaction belt has a perforation track and the suction shoe has a suction port associated with the perforation track.
  • Such a ring spinning machine is known, for example, from DE 197 08 410 A1. It has common drafting systems with, for example, three drafting roller pairs and double aprons, which deliver to the desired fineness stretched Faserlunten. These drafting arrangements are preferably followed by pneumatic compacting devices which, for example, have flexible straps which wrap around a roller and a suction shoe which is under suction. The straps are provided with a perforation track, which are guided over a suction opening of the suction shoe and are sucked to the fibers of the fiber slivers supplied by the drafting systems under compression.
  • the roller looped by the perforated belt is associated with a counterpressure roller.
  • the perforated strap may be disposed above or below the plane of the grain.
  • DE 100 50 089 C2 also discloses a possibility of retrofitting existing ring spinning machines with compacting devices.
  • this solution is limited to very small compacting devices, especially for short staple fibrous materials, in which the compacting belt can be pressed by means of a small pressure roller to the top roller of the pair of output rollers of the drafting system and driven from this.
  • the invention was therefore the object of specifying a way to upgrade ring spinning machines with compression devices in which intervened in the structure of the drafting of the ring spinning machines as little as possible and their default work is accordingly adversely affected as little as possible.
  • the extension of the punch can be done by inserting a correspondingly extended punch or preferably by applying an extension part containing these bearings. If the - short - top roller support and loading arm is maintained, a separate loading device is provided for the top roller of the compactor. However, it is also possible to use a - longer - top roller carrying and loading arm, which contains a separate, additional loading element for the top roller of the compacting device.
  • a ring spinning machine has draw frames on both longitudinal sides, of which only those of one side are shown in the figures.
  • 1, from which the invention is based, has three roller pairs 2, 3 and 4, each with one lower roller 2 ', 3' and 4 'and one upper roller 2 ", 3" and 4 " stored in a punch 5 interrupted here, which are held by two support tubes 6 extending longitudinally through the ring spinning machine 6, of which only one is shown here. whose guide cages are not shown here.
  • the top rollers 2 ", 3” and 4 are guided by means of a support and loading arm 9 and are loaded by means of spring force or pneumatically via handlebar 10.
  • the top rollers 2", 3 "and 4" are, like a later introduced pressure roller, as usual as roller twins executed.
  • a common compression device 11 comprises according to Figure 2, a flexible Verdichtungsriemchen 12, which wraps around a roller 13, a suction shoe 14 and a deflecting rod 15 .
  • the Verdichtungsriemchen 12 has on its circumference in the middle of a perforation track of small holes 16 with a diameter of about 1 mm and passes through a suction opening on the top of the under suction suction shoe 14.
  • the suction line and the suction source are not shown here for clarity.
  • the roller 13 looped around by the compacting belt 12 is provided on the upper side with a pressure roller 17 and on the underside with a drive roller 18 extending over the length of the ring spinning machine like the lower rollers 2 ', 3' and 4 ' over which the roller 13 and above it the pressure roller 17 of each compacting device 11 are driven.
  • FIG. 2 provides for applying to the punch an extension part 19 in which the drive roller 18 is mounted.
  • the extension part 19 can, as outlined in Figure 8, are fastened by means of screws 20 to the punch 5.
  • a loading lever 21 is provided.
  • the load lever 21 through a pin 22 is pivotally mounted at pivot point 23 in a supporting piece 24 which is attached to a line extending through all the punching machine 5 along the supporting rod 25th
  • the support piece 24 may be attached to this support rod 25 angularly adjustable.
  • the support piece 24 rotatably supports on the support rod 25 and is supported by means of a arranged on an arm 26 screw 27 on the support tube 6 and thereby sensitive in its angular position is adjustable.
  • the loading lever 21 is under the tensile load of a tension spring 29 which is mounted on the support piece 24 and the loading lever.
  • the loading lever has an arm 30 on a toggle 31 , by means of which it is pivotable against the pulling force of the spring 29 to give the pressure roller 17 free.
  • the support piece 24 has - as can be seen in particular from Figure 7 - advantageously two cheeks, between which the Loading lever 21 is arranged. This is also advantageous U-shaped executed with two cheeks.
  • Recognizable grooves 33 can be introduced into the cheeks of the support piece 24 , into which the common housing 34 of two suction shoes 14, each associated with two adjacent compression devices 11 , can be inserted by means of rails 35 attached to this housing. As a result, the correct position of the suction shoes 14 can be secured. Support piece 24 and loading lever 21 engage through this housing 34th
  • the fiber structure 36 which enters into it in a wide manner, is shown, which ends in a compacted manner as a narrow roving 37 emerging from the compacting zone.
