Definitions

  • the present invention relates to a locking device for a spinning or twisting spindle of a textile machine according to the preamble of claim 1.
  • Locking devices for the spinning or twisting spindles of textile machines are known and described in detail in numerous patents.
  • the DE 39 34 843 A1 describes, for example, a spinning or twisting spindle which, as usual, has a spindle upper part which is rotatably mounted in a spindle lower part and which serves to receive a spinning head sleeve.
  • the upper spindle part is equipped with a drive whorl, which, acted upon by a tangential belt, drives the upper spindle part during operation.
  • a locking device is arranged, which forms a trigger guard against unintentional removal of the spindle upper part of the spindle lower part.
  • the locking device has a holder which is made of a stamped and bent sheet metal part.
  • a clamped under the flange of the spindle lower part plate has on one side via two tabs for pivotally attaching a spindle brake and on the opposite side via two fork-shaped upwardly projecting legs, which run obliquely towards each other.
  • a securing hook is positioned by means of a kind of clip connection, which protrudes in the operating state with a hook arm in the region of a collar of the drive whirlpool.
  • a disadvantage of this known locking device is the somewhat unstable attachment of the safety hook on the holder by a very simple clip connection.
  • Locking devices for spinning or twisting spindles are also by the German utility model DE 297 21 486 U1 known.
  • These locking devices each have a fixable on the flange of the spindle lower part, vertically arranged holder and a pivotally mounted on the holder locking flap, which prevents unintentional withdrawal of the spindle top part of the spindle lower part in the folded state.
  • the holder is hardened at least in the region of its contact surface on the flange and has sharp-edged projections in this area, which dig into the flange during assembly and in conjunction with a bolt or the like. A relatively secure against rotation, positive connection between the flange and holders ensure.
  • a locking flap On the holder is pivotally mounted by means of a rivet a locking flap, that is, in holes of the side walls of the holder, a rivet is defined, which also passes through a hole in the locking flap, which was previously positioned between the side walls of the holder.
  • the invention has the object, a To provide locking device for spinning or twisting spindles, which is not only very stable and reliable, but also inexpensive to manufacture.
  • a locking device with a holder which has in the region of its rear wall a first, upper recess for receiving a locking flap and a second lower recess for insertion of a fastening means, as well as with a locking flap, which in the installed state with a mounting element in the first, upper recess of the holder is pivotally fixed, has the advantage that a very stable locking device can be produced in a simple manner, with no further separate component is required for fastening the locking flap.
  • dispensing with a rivet and the associated simplification of the handling of the components during their assembly is possible in a relatively simple manner to automate the assembly of the components, resulting in a significant cost reduction in the production of the locking device according to the invention.
  • the locking flap has a weight and stop member with a molded mounting member and a spaced-apart locking latch and with respect to their dimensions and their Material is designed so that the locking bolt can be relatively easily applied by deformation to the front side of the mounting member.
  • the mounting element forms with the adjacent locking latch a pivot member for the locking flap, which is not only easy to manufacture, but also very stable and reliable.
  • the locking flap is, when the mounting member threaded through the first, upper recess of the holder and the locking latch is pressed against the end face of the mounting member, reliably connected to the holder.
  • the holder is so deformable after inserting the mounting element of the locking flap in the first, upper recess of the holder in the region of this recess, that the locking flap pivotally movable, but not removable , is set in the recess.
  • the holder in the region of its second, lower recess positioning lugs, with which the holder is supported in the installed state on the flange of the spindle lower part.
  • the waiver of a grinding of teeth and in this context, at least in places necessary hardening of the holder has a positive effect on the manufacturing cost of the locking device.
  • the mounting position of the locking device in particular the installation depth of the holder, defined can be predetermined and thus easily adjusted to the diameter of the Antriebswirtels the spinning or twisting spindle.
  • the mounting depth of the holder can be adapted to the respective needs, or it is, as set forth in claim 7, a Leksfräsung on the flange, which also serves to accommodate the holder, designed in depth so that the holder can be optimally positioned in the operating state.
  • the Fig.1 shows a arranged in a ring rail 5 a textile machine spinning and twisting spindle. 1
  • Such spinning and twisting spindles 1 each have a spindle upper part 2 and a spindle lower part 3, wherein the spindle lower part 3 serves for the rotatable mounting and vibration damping of the spindle upper part 2.
  • the spindle upper part 2 has a central spindle shaft (not shown) in the drawings, on which, preferably in each case by means of a press fit, a sleeve carrier 6 and a drive whip 4 are fastened.
  • the drive whorl 4 is acted upon by a tangential belt 7, which rotates the spindle upper part 2 during operation of the textile machine.
  • the spindle lower part 3 passes through a corresponding bearing bore in the ring rail 5 and is located with a flange 8 on the ring rail 5.
  • the spindle lower part 3 is fixed to the ring rail 5 by a fastening nut 9, which corresponds to an external thread 10 of the spindle lower part 3 and acts on a washer 11.
  • the spinning or twisting spindle 1 is also equipped with a locking device 12, which has a, preferably by means of a bolt 13, the flange 8 of the spindle lower part 3 fixed holder 14 and a locking flap 15.
  • a preferred, first embodiment of a locking device 12 according to the invention will be described below with reference to FIGS. 2 to 5 explained in more detail.
  • the holder 14 is preferably formed in this embodiment as a U-shaped bent sheet metal part, in the rear wall 16, a first upper, preferably rectangular recess 17 and a second, preferably circular recess 18 are incorporated.
  • the angle-shaped locking flap 15 has a weight and stop member 23, to which a mounting member 24 is integrally formed, and a closure latch 25.
  • the locking bar 25 is positioned on the holder 14 spaced from the mounting member 24 prior to attachment of the locking flap 15.
  • the locking flap 15 can be pushed in this state from the top of the holder 14 and positioned so that the mounting member 24 is disposed in the region of the upper recess 17 of the holder 14.
  • the holder 14 of the locking device 12 is mounted so that between the Antriebswirtel 4 and the front edge of the closure bolt 25, a distance t is ensured.
  • FIGS. 6-8 show a further embodiment of the locking device 12 according to the invention.
  • the holder 14 is preferably formed as a U-shaped bent sheet metal part and has in the region of its rear wall 16, a first, upper, preferably rectangular recess 17 and a second, preferably circular recess 18.
  • the side walls 19, 20 of the holder 14 may, as shown in the embodiment and with reference to the first Embodiment of the locking device 12 explained, also be equipped with positioning lugs 21, 22; However, such positioning approaches are not mandatory if the holder 14, such as in Figure 10 shown positioned in a longitudinal milling 29 of the flange 8 and secured by this L jossfräsung 29 against rotation.
  • the locking flap 15 has, as known in principle from the first embodiment, a weight and stop member 23, to which a mounting member 24 is formed, and a spaced apart from the mounting member 24 locking element 28.
  • the mounting member 24 has in the region of its free end on a small, slightly upwardly drawn nose 27.
  • the locking element 28 is slightly shorter than the locking bolt 25, which comes in the first embodiment used.
  • a gap between the locking element 28 and the mounting member 24 is also given in this second embodiment, so that the locking flap 15 is pushed from above onto the holder 14 and positioned so that the mounting member 24 in the region of the upper recess 17 of the holder 14th is arranged. Subsequently, the holder 14 is embossed, that is, the rear wall 16 of the holder 14 is pushed out slightly to the rear, so that a locking projection 30 is formed.
  • the Arretianssansatz 30 then prevents, preferably in cooperation with the nose 27 of the mounting member 24 that the locking flap 15 can solve the holder 14 again.
  • FIGS. 9 and 10 show, respectively in front view, a spinning and twisting spindle. 1
  • the locking devices 12 of this spinning and twisting spindle 1 are each slightly modified in the region of the attachment of their holder 14 on the flange 8 of the spindle lower part 3.
  • the holder 14 is fixed by means of a screw bolt 13 in a recess 31 of the flange 8, while the holder 14 at the in Figure 10 embodiment shown in a longitudinal milling 29 of the flange 8 is positioned.
  • the installation depth t of the locking device 12 that is, the distance between the folded locking flap 15 and drive whorl 4 can be given in a simple manner.
