  • a time-switch is released, for instance a pressure switch mounted on the pick-up means 50 or alternatively by means of a photo-cell arrangement controlling the presence ofa bag in the position shown in FIG. 2, with the effect that the linear motor is anew reversed such that a new bag is automatically picked up, dispensed and held open in the rack, etc.
  • a device or rack in accordance with the invention may be modified in various manners within the scope of the inventive idea, and in the foregoing description one has only described the main parts since it will rest within the skill of art to provide for the desired actuating and control of the varying moving parts of the rack.
  • the design of the pick-up means together with the complementary cut-outs or serrations 72 and 74 in the outermost bag panel can be eonfigurated in several ways.
  • the invention utilizes a reciprocating pickup means which co-operates with complementary serrations in the outermost bag panel, leaving an open bag space between the pick-up means and the bag magazine.
  • FIGS. 5 and 6 illustrate a lateral view and a plan view, respectively, of a modified embodiment of an apparatus in accordance with the invention
  • FIG. 7 is a fragmentary view illustrating how the bag in this case is designed, and how it is supported in open fashion in the apparatus rack.
  • the reference number designates the supporting frame comprising a bottom part 102 and an upright housing part 104, housing a bag magazine 106 which in this embodiment comprises an upwardly inclined supporting rail means 108 comprising rails 152 and 154 for the supply of bags 110, and which is kept compressed by means of spring means 112 pressing the bag supply upwardly and biased against an upper stop knob 114 at the outer ends of the rail means.
  • a bag magazine 106 which in this embodiment comprises an upwardly inclined supporting rail means 108 comprising rails 152 and 154 for the supply of bags 110, and which is kept compressed by means of spring means 112 pressing the bag supply upwardly and biased against an upper stop knob 114 at the outer ends of the rail means.

  • An inclinedbag magazine as shown implies two advantages. Firstly, one saves space laterally and also in the upward direction. In other words, the magazine may contain more bags per square area of the rack housing 4.
  • a further advantage with this embodiment for the magazine rests in that the picking member gets a better biasing action against the outermost bag panel or the serrations in same, since the bag panels on the inside of the same will not be in complete register with each other but somewhat laterally displaced, such that the handle openings and the special serrations in the outermost bag panels will not be positioned straight backwards.
  • FIGS. 5 and 6 will principally operate analogous with the apparatus shown in FIGS. 1 3 with a bag as shown in FIG. 4, but the apparatus of the second embodiment presents, among others, the advantage that it can be made entirely open to both sides 158 and 159, making it possible to remove the bags to either side, and the design makes it possible to make a more compact unit.
  • FIGS. 5 and 6 illustrate the operative situation wherein a bag 160 has just been picked up by the pickup arms 132, 134 by a forward action of the swing arm 116, this now being in its return movement.
