Definitions

  • the invention relates to a device for coupling a heald frame or a loom of a loom with a heald frame, in particular lateral guides for the heald frame are provided and the heald frame is connected to the dobby by angle levers.
  • a device for coupling a heald frame with a heald frame in which the coupling end of the heald frame is designed as a hook with a mouth for receiving a correspondingly shaped counterpart of the heald frame.
  • the shaft pulling hook is provided with a support adjoining the mouth for supporting the counterpart and can be fixed in a first swivel position in which the counterpart can be lowered freely onto the support.
  • each of the two rows of shaft pulls is assigned an adjusting and an adjusting member.
  • the disadvantage here is that the device has a relatively complicated mechanism and manipulations are required during the coupling process, which are unsuitable for automation.
  • the object of the invention is to provide a device of the type mentioned at the outset, which is not only simple and reliable, but also suitable for automated operation, in particular with robots.
  • a coupling sleeve with a cavity for receiving a coupling member, the cavity having at least one tooth-like projection, which engages in a corresponding recess of the coupling member when the coupling sleeve and coupling member are aligned and, and furthermore, the cavity opposite the respective projection an extension has such that a relative pivoting of the coupling sleeve and coupling member for disengaging the tooth-like front jump and release of the clutch is guaranteed.
  • the coupling only by lateral pivoting e.g. the shaft pulls can be brought into a position which enables the coupling to be released or the heald frame to be pulled out.
  • Moving parts such as bolts, adjustment hooks etc. can thus be dispensed with.
  • the actual coupling only consists of two interlocking moving components. This also makes the use of robots possible in a simple manner, for example by With appropriate grippers the heald frame or an entire shaft package can be replaced.
  • laterally displaceable guides 14, 16 are provided on the side walls 11, 12, in which heald frames 18 (only the first one provided with the reference number) are guided so as to be displaceable in the vertical direction.
  • a heald frame 20 connected to the one side wall 11 is used to drive the heald frames 18.
  • Each shaft clamp 22 of the heald frame 20 is connected to the shaft drawbars 32, 34 via a drive lever 24 and various angle levers 26, 28 and push rods or pull rods 30, which are telescopically longitudinally adjustable in a known manner.
  • a coupling sleeve 36, 38 with an essentially rectangular cross section is arranged on each shaft pull rod 32, 34 Has cavity 40 for receiving a coupling member 44, 46 attached to the shaft frame 42.
  • each shaft frame 42 has two coupling members 44, 46. Accordingly, two shaft pull rods 32, 34 are provided per heald frame 18.
  • the number of shaft drawbars 32, 34 per heald frame 18 can vary; with very narrow weaving machines, e.g. Ribbon looms, one shaft feed per heald frame 18 is sufficient; in the case of wide looms, three or more shaft drawbars 32, 34 can be provided per heald frame 18.
  • the cavity 40 has two tooth-like projections 48, 50 which engage in corresponding recesses 52, 54 of the coupling member 44 when the coupling sleeve 36 and coupling member 44 are in alignment. Furthermore, the cavity 40 has an approximately wedge-shaped extension 56, 58 relative to the respective projection 48, 50.
  • the bottom 60 of the coupling sleeve 36 is designed as a slideway with a cylindrical outer surface on which a correspondingly designed sliding surface 62 of the coupling member 44 is supported.
  • the angle levers 28 are approximately in a position M corresponding to the middle position of the heald frame, the shaft pull rods 32, 34 being in a vertical position.
  • the top dead center of the angle lever 26, 28 is denoted by A, the bottom by B.
  • groove-like side stops 64, 66 are arranged, which according to the enlarged detailed illustration in FIG. 3b have a groove 68 for each shaft pull rod.
  • the lateral guides 14, 16 are now shifted to the right by the distance L in the direction of the arrow 70, the shaft pull rods 32, 34 being pivoted to the right by the angle ⁇ (FIGS. 3c, 4, 7a, 8) and the individual shaft pull rods 32 , 34 are supported in the grooves 68.
  • the tooth-like projections 48, 50 are disengaged from the recesses 52 and 54, respectively, by moving the coupling member 44 against the abutment surfaces of the extensions 56, 58, the sliding surface 62 of the coupling member 44 along the floor 60 of the coupling sleeve 36 slides. In this position, the unlocked coupling can be released and the shaft frame 42 or the entire shaft package can be lifted out according to arrow 72 (FIGS. 3c, 4).
  • the new shaft frame or the new shaft package is reinserted in accordance with arrow 74 and the coupling is closed again by moving the guides 14, 16 back to the left or pivoting the shaft pull rods 32, 34 to the left.
  • the coupling member 44 is screwed onto the heald frame 42 via a flange 84 by means of screws 86, 88.
  • the upper extension 56 is closed by a resilient striking plate 90 fastened to the screw 86 for the purpose of rejecting thread flight, which would otherwise accumulate in the extension 56 and could hinder the pivoting movement between the coupling member 44 and the coupling sleeve 36. Since the striking plate 90 is resilient, it does not hinder the pivoting movement.
  • the coupling member 44 is fastened in the heald frame 42 via a known elastic torsion coupling 92 with a rubber bushing 94.
  • the flank 49 or 51 of the respective tooth-like projection 48 or 50 is curved in such a way that a wedge-like tension is ensured when it snaps into place.
  • the coupling device 36, 44 can also between the shaft machine 20 and the shaft pull e.g. attached to the location of the swing arm 22 and operated in the manner described.
