Definitions

  • This invention relates to an apparatus for mounting a harness in a weaving machine. More particularly. this invention relates to an apparatus for mounting a harness containing a reed, heald shafts and contact and/or guide rails for stop motion droppers in a weaving machine.
  • a harness containing various components such as a reed, heald shafts, and the like, has generally been brought to the weaving machine on a conveying device together with a freshly wound warp beam.
  • the harness which is held in a common mounting and contains the draw-in ends of the warps wound on the new warp beam has then been lifted manually from the conveying device, which remains outside the machine, and placed in the corresponding guides and retaining means in the weaving machine.
  • the invention provides an apparatus which is mounted on a weaving machine to move a harness from a position adjacent the machine to a position within the machine so that the machine components mounted in the harness can be mounted in position in the machine.
  • the apparatus includes an upwardly projecting supporting structure which is mounted on the upright supports of the weaving machine, a pair of beams, each of which is mounted on the supporting structure above the weaving frame to project over either the part of the machine to receive a harness or a station provided for the harness outside the ground plan of the machine, and lifiing means on each beam which are guided along the beams to lift and lower the harness.
  • the apparatus functions so that a harness can be lifted from a conveying device to a desired height above the conveying device, pushed horizontally across the weaving machine by an operator. and lowered to position the various assemblies into the respective guides on the machine for operation.
  • the two beams are in the form of booms which can be pivoted at one end and are so attached to the associated supporting structures as to be horizontally pivotable.
  • Each of these beams also has its own lifting means.
  • the beams forming the booms can be relatively short, and can be swivelled into a first position above the station for the harness outside the machine and into a second position above the appropriate portion of the machine.
  • the two beams are situated at approximately the same height and the length of each is less than half the width of the weaving machine.
  • the two beams are mounted approximately parallel to one another on a crossbeam connecting the free ends of the supporting structures while the lifting means are guided in planes parallel to the beams.
  • a relatively compact and highly stable apparatus can be obtained, according to a further feature of the invention, if the two supporting structures are fixed to the uprights of the weaving machine. Further, since the apparatus is to be connected to a relatively heavy and necessarily stable base of a weaving machine, the apparatus can be particularly light in construction, so that the operators can easily place the apparatus on one weaving machine and, if necessary, remove it after insertion of the harness for use on another machine.

  • the weaving machine I is a gripper shuttle weaving machine in which weft bobbins (crosswound bobbins) remain outside the shed during weaving and are mounted on a bobbin carrier 3 (FIG. 2) attached to the weaving-machine base.
  • the drawings show only those components which are most important in a description of the operation of the machine I.
  • the machine base has two upright (lateral supports) 6, 7, which are connected by crossbeams 4, 5 and each of which carries, at the warp end of the machine, a warp beam bearing 8 and a mounting 9 for a tension beam I0.
  • a hinged retaining strap 20 is pivoted on the warp beam bearing 8 in order to retain a warp beam shaft therein.
  • Each of the two ends of the tension beam 10 is rotatably mounted on a swing lever II which is fixed to a supporting beam 12 secured in the mounting 9.
  • guide rails 14 for a warp stop motion 13 are fixedly mounted on comb-like brackets 15 on the uprights 6, 7 to lie across the uprights 6, 7.
  • the brackets 15 are also provided with guides for contact rails I6 for the warp stop motion 13, these contact rails being inserted in the brackets and displaceable horizontally along them.
  • the contact rails 16 and guide rails 14 are also supported on brackets (not shown) placed at intervals across the width of the machine.
  • the uprights 6, 7 also contain vertical guides I7 for heald shafls 18, which can be displaced up and down therein, and bearings for a sley 21 (pivotable as indicated by arrows 19), a rotatable rough-surfaced cloth draw-ofi' roller (sand beam) 23 and a cloth beam 26.
  • a breast beam 22 also connects the uprights 6, 7, while a reversing roller 24 which bears on the cloth draw-off roller 23, and a cloth guide bar 25 are also disposed across the uprights 6, 7.
  • the weaving machine is set aslant, with the machine base raised at the warp end, so that large-diameter warp beams can be used.
  • an apparatus for mounting a harness in the machine I includes a pair of supporting structures 31, 32 mounted on the machine base and a horizontally pivotable boom 33, 34 pivoted on each of the mutually facing sides of the supporting structures, at the same level above the machine 1.

  • Each of the booms 33, 34 also has a fork-like pivot element 46 with two connecting lugs 47, 40 placed one above the other which are joined by a continuous vertical pivot 49 to two corresponding lugs 51, 52 fixed to the column 36.
  • the length of each boom 33, 34 is somewhat less than half the distance between the two uprights 6, 7, so as to be swivelled horizontally without touching one another, over part of the weaving machine 1 and over a station provided for a conveying device 53 outside the ground plan of the machine at the warp end of the machine.
  • the two pairs of wheels 44 are mounted on two lugs 54 which project from the slot between the lower flanges 42a, 43a and are connected by a pin 55 beneath the boom 33, 34 to a lug 56 fixed to the lifting gear 45.

  • the warp yarns 94 are passed from the warp beam 93 over the guide rod 98 and each is drawn through one of the stop motion droppers 97 beneath the contact rails 16 (FIG. 4) and passed over the guide rod 98a to the heald shafts l8, and each is drawn through an eye on one of the warp healds 104 and then through the reed 100.
  • the ends of the warps 94 projecting from the reed 100 are knotted together in groups.
  • the conveying device 53 When weaving begins, or in order to replace an empty warp beam, the conveying device 53, loaded with the full warp beam 93 and harness 106, is brought to a station behind the machine, that is, at the warp end.

  • the motors for the two sets of lifting gears 45 are switched on simultaneously by means of a control signal, and the harness 106 is lifted high enough from the conveying device 53 for the undersides of the heald shafts 18 to be higher than the tension beam or other corresponding components of the machine in this area.

  • the harness 106 suspended over the weaving machine I is now lowered, the contact rails 16 being first inserted in the brackets and so brought into their operative position (broken lines in FIG. I) so that the lower ends of the stop motion droppers 97 come between the guide rails 14.
  • the chains 115 are then removed from the conveying brackets 99 (so that the devices 107, being loaded only at one end by the shafts 18, move askew), and the shafts 18 are brought into their guides 17 and so into their operative position (broken lines in FIG. I) and connected to a driving device (not shown).

  • the stop motion droppers 97 sitting on the tensioned warp yarns 94 are lifted off the associated contact rail 16 by means of the cross-pieces which close their eyes at the top.
  • the lateral arm of the eyes touch the lateral surfaces of the contact rail 16 barely or not at all. if one of the warps 94 breaks, the dropper 97 resting on it falls on to the contact rail l6, closing a circuit and so producing a signal to stop the weaving machine.
  • the guide rails 14' for the warp stop motion which can, instead of being fixed to the machine, be detachable like the contact rails 16.
