Definitions

  • the invention relates to a load carrier for drafting systems of a spinning machine with a pressure roller receiving, to a stationary support bar pivotable support on which a load lever is pivotally attached, which is connected to take the carrier with it via a towing connection, which in the closed position at one the locking bar attached latch can be locked and which can also be locked in the open position.
  • the invention has for its object, while maintaining a simple structure of the load carrier, so that both opening the drafting system and transferring the load carrier from the open position in the closed position, ie the operating position, can be carried out with one hand.
  • This object is achieved in that the loading lever is guided on a predetermined movement path by means of a guide element which is fixed with respect to the holding rod in such a way that the loading lever can only be moved further around the holding rod after a predetermined pivoting path in the opening direction when the carrier is also pivoted along, and that the latch is provided with a detent assigned to the open position, into which the loading lever can be locked with a locking element from the fully swiveled-out position.
  • This training enables full one-handed operation, i.e. Both opening and closing can be done with just one hand.
  • the load lever not only secures the closed position, i.e. the operating position, but also the open position. It is therefore only necessary to adjust the loading lever by hand.
  • the load carrier essentially contains two elements, namely a carrier (14) and a load lever (15).
  • the carrier (14) is made from a bent sheet metal profile, which has an essentially U-shaped cross section (FIG. 2) and, in the side view (FIG. 1), the shape of an unequal angle.
  • the short leg (25) is mounted on a stationary holding rod (13) which runs through in the longitudinal direction of a spinning machine.
  • the long leg (26) carries top rollers (10, 11, 12), which are not shown, stationary, driven bottom rollers are assigned. These lower rollers are usually stored in punches and provided with a drive at the end of the machine.
  • the arrangement of the top rollers (10, 11, 12) is the subject of the older patent application P 38 23 872.1. Since their arrangement is of no importance for the present invention, it is not further explained here.
  • the load lever (15) also has the shape of an irregular angle in the side view (FIG. 1). It is formed from a flat steel.
  • the short leg (29) of the loading lever (15) is mounted on the short leg (25) of the carrier (14) so as to be pivotable about an axis (23) which runs parallel to the holding rod (13). This axis (23) lies at least approximately in the plane of the stretching field and on the side opposite the pressure rollers (10, 11, 12) with respect to the holding rod (13).
  • the loading lever (15) is led out of a slot (24) in the carrier (14). Its long leg (28) runs essentially parallel to the long leg (26) of the carrier (14). This long leg (28) is provided with a stop (31) which lies in the closed position, the operating position, and in the fully open position on the top of the carrier.
  • the loading lever (15) is provided in the region of its short leg (29) with a locking bolt (19) protruding on both sides, onto which sleeves (32) acting as rollers are attached (see Fig. 2).
  • the locking bolt (19) is assigned a bolt (16) which is stationary on the holding rod (13).
  • the bolt (16) consists of two plates (Fig.2), which are interconnected by at least one cross bolt (27).
  • the bolt (16) is fixed in an adjusted position on the holding rod (13) by an adjusting screw (33) and a fixing screw (34).
  • the bolt is provided with a catch (20) in which the locking bolt (19) engages in the operating position. In this operating position, the loading lever (15) pulls the carrier (14) into the operating position via the axis (23).
  • the loading lever (15) is connected to the bolt (16) via a guide bracket (17).
  • the guide tab (17) is articulated on a linkage (21) on the bolt (16), which in the closed position lies approximately in the plane of the locking bolt (19) and the axis (23).
  • the tab (17) engages around the locking bolt (19) next to one of the sleeves (32) with an elongated hole (22), the greater length of which is aligned radially to the linkage (21).
  • the loading lever (15) can be pivoted around the axis (23) with which it is held on the carrier (14) by gripping with one hand on a handle button (30) located at its end.
  • the locking force applied by the loading devices of the pressure rollers (10, 11, 12) is overcome.
  • the loading lever (15) pivots essentially around the axis (23) with which it is held on the carrier (14).
  • the tab (17) runs with it.
  • the carrier (14) has not yet been moved up to this open position.
  • the loading lever (15) To close the drafting system, the loading lever (15) must be disengaged from the catch (18), for which purpose it is pivoted together with the support (14) in such a way that the locking bolt (19) moves relative to the tab (17). After this disengagement from the catch (18), the loading lever (15) can be raised and then pivoted back, the carrier (14) also carrying out an inevitably guided movement. As soon as the loading lever (15) reaches its position according to Fig. 3 again when swiveling back, the pressure rollers (10, 11, 12) rest on the lower rollers. The further closing movement with which the loading lever (15) is returned to the position according to FIG. 1 again leads to the entire load carrier being locked by the locking bolt (19) engaging in the catch (20).
