Definitions

  • the follower 72 engages the upper straight surface 78 of the cam 70 to locate the arms 62 and 64 in the retracted position of FIGURE 1, and when the arms 56 and 57 are elevated to the FIGURE 3 position, the follower moves along the surface 78 to the surface 80 to raise the auxiliary support arms 62 and 64 into the operative stack-supporting position of FIGURES 3-6 for supporting the stack from below at the carton base 13.
  • the surface 78 is the fast surface of the cam and produces a more rapid up or down movement of support arms 62 and 64 than the corresponding movement of the arms 56 and 57.
  • Surface 80 effects a slow movement of support arms 62 and 64 and serves to position them in proper stack-supporting position when arms 56 and 57 have completed their upward movement.
  • a finger assembly is provided for separating and bending the front locking flap 20 of the bottom carton away from the locking flap of the carton next above.
  • the assembly 120 comprises a pair of parallel arms 122 pivoted to the frame members 40 and 42 by aligned pivots 124.
  • the arms 122 are connected by a rotatable shaft 126 pivoted at 128 to a rod 130 which is also pivoted at 132 to the arm 134 of a bellcrank lever 136.
  • the bellcrank lever 136 is pivoted at 137 and its other arm 138 has a follower 140 held in engagement with the periphery of cam 84 by spring 139. When the follower 140 is in engagement with the circular periphery 142 of the cam 84,
  • Edges 162 comprise the end portions 166a and the intermediate portion 166]) of two parallel sides.
  • Ad jacent edges 164 extend longitudinally for the entire length of the other parallel sides of the tray. Any of these edge portions 166a, 1661) or 164, or combinations of such edge portions of the endmost tray can be bent or deformed out of the normal plane of such edges to provide the enlarged opening or openings between such edge portions and similar corresponding edge portions of next adjacent trays for smooth and easy entry of elements that will pry such endmost tray from the nested stack of which it has been a member.
  • the apparatus hereindisclosed have been designed to operate upon nested stacks of the containers illustrated in FIGURES 7A through 7C and described above.
  • the inventive concept of creating an enlarged opening or openings between corresponding edge portions of adjacent containers is utilized for each of such nested stacks by components in the apparatus, whereby prying or separating elements or components enter such enlarged opening or openings to complete the step of separating an endmost container from the nested stack.
  • Movement of the stripper assembly 46 from the FIG- URE l to the FIGURE 3 position produces a movement of the auxiliary support arms 62 and 64 from the lower retracted position of FIGURE 1 to the upper support position shown in FIGURE 3 and also in FIGURE 4, the stack being supported by the blade 34 at the flap end, and the arm rests 68 disposed about 4" below the bottom carton.
  • the blades are formed to provide cutouts 34 and 48' along their rear edges to clear the fingers 146.
  • the stripper blade 48 is shaped between the cutouts as shown in FIGURE 2.
  • the pointed rear edge portions of the stripper blade between the cutouts permits entry thereof between the cells of. the carton and beyond the hinge connection of the lid-locking flap.
  • the points along the rear edge are aligned with the spaces between the egg cells 14, and the rounded contour on either side of each point conforms to the cell configuration.
  • said separator comprises at least one finger having a surface adapted to engage said flap of said bottom carton to bend said fiap downwardly away from said flap next above thereto and means moving said finger so as to bend said flap.
  • said separator comprises at least one finger having a surface adapted to engage and bend said bottom carton edge portion away from the like edge portion of the carton next thereto above, said finger is spring biased toward said bottom carton edge portion.
  • a chute for said stack of cartons the combination comprising a movable blade for intermittently supporting said stack of cartons in said chute,
  • apparatus means adapted to engage and bend said accessible edge portion of the endmost carton in a direction away from its normal position in said stack so as to provide an enlarged spaced opening between 5 said endmost and next adjacent cartons at said portions, dual carton separating means adapted to enter said enlarged spaced opening in a smooth and facile manner so as to engage said adjacent cartons, one of said latter means engaging said endmost carton, another of said latter means engaging said next ad; jacent carton, in said stack, said carton separating means adapted to pry said endmost carton from said stack upon movement of either of said carton separating means in a direction relatively away from the other of said carton separating means.
