Definitions

  • the invention relates to a load carrier for drafting systems of spinning machines with a carrier which can be pivoted about an axis parallel to the top rollers and to which holders for top rollers are attached, of which at least the one located on the inlet side with a screw projecting upwards from the carrier a longitudinal guide is held adjustable, and with a lockable in the operating position, pivotally arranged loading lever.
  • the field widths ie the distances between the pairs of bottom rollers and top rollers, in order to adapt them to the material to be processed.
  • the fixed point of the field widths is the fixed pair of output rollers. Since in many cases the middle pair of rollers in a three-cylinder drafting system is provided with an upper apron and a lower apron, which specify the field width, this pair of rollers is generally only adjusted when the aprons and apron cages are exchanged. With regard to the pair of input rollers, in most cases the field width setting is carried out in such a way that the distance between the top roller and the associated bottom roller is changed from the middle roller.
  • the adjustment of the lower rollers takes place in that they are adjusted with the adjustable slide in which they are mounted.
  • the mounting of the top roller is adjusted accordingly in the longitudinal direction of the carrier.
  • the screw holding the holder on the carrier is loosened, the holder is moved and the screw tightened again.
  • This is usually carried out in such a way that the loading lever and the carrier are pivoted out of the operating position, so that the screw or screws of the holders are accessible for a tool. In the operating position, however, the screws are covered by the load carrier.
  • the setting of the top roller or top rollers is inevitably relatively imprecise, since the tolerances between the screw, the holder and finally the axis of the top roller in question add up.
  • the invention has for its object to provide a load carrier of the type mentioned, with which a more precise field width setting is possible than before.
  • the loading lever is shaped and / or recessed in such a way that at least the screw associated with the holder on the inlet side is accessible to a tool when the loading lever is in the operating position.
  • a method for setting field widths on load carriers in which the top rollers are held in a carrier by means of detachable and fixable brackets, which one in operation Position locked locking lever is assigned, an adjustment gauge is attached to the axis of at least the top roller facing the inlet side, and the bracket of this top roller is fixed with the loading lever and carrier in the operating position relative to the carrier.
  • the load carrier shown in FIGS. 1 and 2 contains a carrier (10) and a load lever (24).
  • the carrier (10) which is formed from a sheet metal profile which is bent in a U-shaped cross section, can be pivoted about a stationary axis (14) which is designed as a holding rod which runs in the longitudinal direction of a spinning machine.
  • the loading lever (24) is fastened to the carrier (10) by means of a pivot axis (25) parallel to the axis (14), a locking device (42), which is not explained in more detail here, being provided to secure the operating position of the carrier ( 10) and load lever (24).
  • holders (16, 17, 18) In the U-shaped, downwardly open profile of the carrier (10), holders (16, 17, 18) are used, which act as pressure rollers hold twin-trained top rollers (11, 12, 13).
  • the middle top rollers (12) are provided with an apron guide.
  • the brackets (16, 17, 18) are fastened to the carrier (10) by means of screws (19, 20, 21), the lenticular screw heads provided with a hexagon recess protruding upward from the carrier (10).
  • longitudinal guides (22, 23) extending in its longitudinal direction are provided in the carrier (10), in which the holders (16, 17) after loosening the Screws (19, 20) can be moved and fixed in new settings by tightening the screws (19, 20).
  • the loading lever (24) is formed from a flat iron, which is mounted in the axis (25) between the two legs of the U-shaped support (10).
  • the carrier (10) is provided in the region of its end facing the inlet side with a slot (31) through which the loading lever (24) emerges, which then in the operating position has a leg (30) essentially parallel to the carrier (10) extends and rests at its front end with a load stop (26) on its top.
  • the section (27) of the loading lever (24) arranged on the axis (25) runs in the longitudinal center plane of the carrier (10), as can be seen from FIG. 2.
  • a section (28) forming the front end of the loading lever (24), to which a handle (15) is attached, also lies in the same longitudinal center plane.
  • the middle one Section (29) remains within the contour, which is predetermined by the width of the carrier (10). Since the load carrier (24) ends in front of the screw (21) of the output top roller (13), all screws (19, 20, 21) are accessible even when the drafting system is closed, ie when the carrier (10) and the load lever (24 ) are in the operating position shown in Fig. 1.
  • the field width setting in particular between the top rollers (11 and 12), is carried out with the carrier (10) and loading lever (24) in the operating position.
  • the screw (19) is loosened so far that the holder (16) with the upper roller (11) can be moved.
  • An adjusting gauge which is shown in FIG. 3, is then placed on the axis (14) designed as a holding rod.
  • This setting gauge has a base body (35), to which two side rails (34) are first attached by means of a screw (37) and pins (36).
  • These rails (34) have a recess adapted to the axis (14) designed as a holding rod, with which they can be placed on this axis (14).
  • the distance between the two rails (34) is selected so that they can be placed laterally from the carrier (10) in the operating position onto the axis (14).
  • Two further lateral rails (33) are fastened to the base body (35) of the setting gauge and can also be guided laterally past the carrier (10) in the operating position.
  • the rails (33) are provided with cutouts which are adapted to the axes (32) of the upper rollers (11) and which can be plugged directly onto them.
  • the rails (33) are firmly connected at their end opposite the cutouts by means of a screw bolt (38), by means of which they are kept at a distance. They are provided with slot guides (40), through which screws (39) pass, which are screwed into the base body (35).
  • the base body (35) is provided with upper and lower guide stops (41) so that the rails (33) have a defined position relative to the rails (34). have to take.
  • the rails (33) are set by loosening the screws (39) and moving the rails (33) in their slot guides (40) to the desired distance between the axes (32) of the top rollers (11) to the axis (14) and then fixed .
  • this setting gauge fixed with the desired setting, the upper rollers (11) are then set on the individual drafting systems.
  • the setting gauge is hooked into the axis (14) with the recesses of the rails (34) and into the axes (32) with the recesses of the rails (33).
  • the screw (19) is then tightened so that the top rollers (11), ie the top roller twin, are set in the exact position.
  • setting gauges for the top rollers (12) can of course also be provided.
  • an adjustment of the upper rollers (12) is generally not provided, since otherwise the distances of the apron guide from the pair of output rollers no longer have the correct values.
