Definitions

  • the invention relates to a method and means for alternately arranging warp failure detectors in a row to form a package from which the individual detectors can be consecutively separated by a machine for threading or mounting the detectors on the warp threads of a Weaving machine.
  • the detectors usually are in the form of laminae whose outlines are asymmetric to afford separation of the detectors from the package.
  • the detectors or laminae are arranged alternately with respect to their asymmetric contours so that consecutive separation of the outermost and only the outermost detectors from the package is facilitated.
  • New laminae are either arranged in packages wherein the laminae are not alternately placed or they are loose and do not form packages. It is not difiicult to place the laminae of equal outlines to form packages. Transformation of such packages into packages wherein asymmetric laminae are alternately arranged, by hand takes a long time.
  • laminae of equal outline are placed in like position on a first carrier bar to form a row thereon and laminae of equal outline are placed on a second carrier bar which is substantially parallel to the first carrier bar, in mirror-inverted relation to the laminae on the first carrier bar whereupon the outermost laminae of the rows of laminae on said bars are alternately and consecutively separated from the other laminae of the respective row and are swung toward each other for alining threading holes in the laminae and forming a package of laminae wherein the laminae of one now alternate with the laminae of the second row.
  • the apparatus includes two substantially parallel horizontal carrier bars, each bar supporting a row of detectors, the detectors on one bar being in mirror-inverted position relative to the detectors on the second bar, a conventional mechanism for alternately and consecutively separating the outermost detectors of said rows, and guide means for swinging the detectors hanging on the first bar and on the second bar toward each other for alining threading holes in the detectors and forming a package of detectors wherein the detectors of one row alternate with the detectors of the second row and the threading holes of all detectors are alined.
  • FIG. 1 is a diagrammatic perspective illustration of a carrier bar supporting a plurality of warp failure detectors.
  • FIG. 2 is a diagrammatic top view of an arrangement according to the invention.
  • FIG. 3 is a diagrammatic perspective illustration of the arrangement shown in FIG. 2.
  • FIG. 4 is a perspective illustration of a carrier pin supporting a plurality of warp failure detectors in alternatingly mirror-inverted relation.
  • numeral 1 designates warp failure detectors as used for checking the warp threads in a weaving machine.
  • the size and configuration of the detectors and necessary apertures such as are designated by numerals 2 and 3 depend on the conditions under which the detectors operate.
  • detectors are fed to the machine from packages.
  • detectors of at least two different contours are alternately arranged in mirror-inverted relation in the package.
  • the detectors or laminae preferably have an asymmetric outline whose configuration depends on the type of apparatus which is used for separating the detectors from the package and must also be such as to reduce the cost of manufacturing the detectors.
  • the aforementioned asymmetry may be obtained, for example, by a one-sided grinding off of a part of a plurality of detectors which are held in a package for this purpose. As can be seen in FIG. 1 the initially round top of the detectors 1 is ground ofi at one side to produce an inclined surface 5.
  • the detectors be presented to the threading or mounting apparatus from packages wherein the detectors are placed in alternately mirror-inverted position.
  • the detectors are filed in rows on carrier bars 6, 6' whereby, for example, the detectors 1 are arranged on the carrier bar 6 with the bevelled top surfaces 5 declining to the left in FIG. 1 and all detectors 1' are arranged on the carrier bar 6' with the bevelled top surfaces 5' declining tothe right as shown in FIGS. 2 and 3.
  • the carrier bars 6, 6' are placed in parallel or almost parallel relation and guide the detectors arranged thereon to a dividing apparatus 10, for example, as disclosed in Patent No. 2,512,165.
  • This dividing apparatus includes grippers 11 and 12 which alternately engage the detectors arranged on the bars 6 and 6, respectively, in consecutive order and move the seized detectors in the direction indicated by the arrow a.
  • An apparatus for alining warp failure detectors having an asymmetrical configuration, in alternatingly mirrorinverted relation, each detector having an upper and a lower aperture, comprising:
  • said first carrier bar extending through the upper apertures of a group of detectors placed in equal relative position and hanging on the first carrier bar
  • said second carrier bar extending through the upper a a apertures of a second group of detectors placed in ends facing the separated detectors and receiving the movequal relative position and hanging on the second ing detectors between said ends and causing the detectors carrier bar in mirror-inverted relation to the deof one group to swing towards the detectors of the second tectors of the first group, group while moving between said ends into the space bemeans for alternatingly consecutively separating the 5 tween said guide rails.
  • An apparatus as defined in claim 1 including a horimost detectors of the second group and for moving Zontal guide rod received in the alined lower apertures. the separated detectors of the first group on the horizontal first bar and for moving the separated de- References Cited y the Examine!
