Definitions

  • the invention relates to a device for opening boxes of the type formed of foldable sheet material in which the boxes are folded flat in manufacture to provide opposite side and end walls, and a bottom superimposed and interconnected along fold lines, said device comprising a stationary frame, a hopper means secured to said frame for maintaining a supply of flat unopened boxes and delivering the lowermost of them and hook means for engaging and erecting said walls.
  • a further disadvantage of the known devices is, that they are rather complicated.
  • the invention aims to provide a device of the recited type, that occupies less floor area and due to a simple construction is cheap and reliable.
  • said hooking means comprising two oppositely mounted hook devices, each having a hook pivotably mounted about a shaft, a pivot driving means for pivoting said hook about said shaft and a further driving means for imparting to said hook a movement having a radial component with respect to said shaft.
  • the horizontally oriented down-fall of the boxes is safeguarded by providing that below said hopper flaps having a plane surface are present pivotable from a position in which they protrude into the space below the lowermost flat unopened box and their upper surface is mainly horizontal and a position in which the said plane surfaces tilt downward toward said space and are located outside said space.
  • flaps of this type are known per se from the German Patent Specification 658,581, but with a falling height that does not allow the objects to be positioned obliquely, so that the insight, that such flaps prevent obliquely falling down of flat objects cannot be learned from this publication.
  • drawing reference 1 indicates a hopper in which a stack of folded boxes 2 is present, wherewith it is indicated that the stack may be considerably higher than has been shown in the drawing.
  • This stack rests on stop members 3, which, as has been shown clearly in fig. 2, can be moved from a position in which they support the stack (solid lines) into a position in which they are not located inside the hopper so that they cannot- support the stack.
  • the member 5 is coupled to an activation arm 7 which by means of an activation link 8 enables movement of the member 5 from the position shown in solid lines into the position indicated with interrupted lines.
  • a retaining member 9 has been shown, that by means of a pneumatical cylinder 10 can move from the position shown in solid lines into a position that is retained from the stack and vice versa.
  • Stack release members 11 are movable about a shaft 12 and can be moved from the position indicated with solid lines into the position shown with interrupted lines. In the position shown with solid lines they are inactive but when they have pivoted upward into the position shown with interrupted lines they come below one of the objects 2 and lift it somewhat, together with the stack positioned higher up, so that the members that support the stack or have to retain it are considerably released.
  • flaps 14 are mounted pivotably about shafts 13, which flaps by means of an activation arm 15 and an activation link 16 can be moved from the position shown in solid lines into the position shown in interrupted lines and vice versa.
  • a shifting member 18 that is movable in horizontal direction can remove an object laying on the roller track toward the left in fig. 1.
  • hooks 19 have been mounted, which can be activated pneumatically by means of pneumatical cylinders, which themselves can be pivoted by means of an arm 21 about a shaft 22 from the position shown in solid lines into the positions shown in interrupted lines and vice versa.
  • the line 3 indicates the position of the stop members wherewith the lower level corresponds to the position shown in fig. 2 with solid lines and the higher part corresponds to the position shown in that figure in interrupted lines.
  • the retaining members 5 are in the time period that corresponds to the high level of this line in the position shown in solid lines, consequently outside the hopper 1 and in the lower part of line 5 in the position in which they cooperate with the stack.
  • the line 9 shows also in the higher part of this line the position in which the members 9 do not cooperate with the stack, whereas in the lower part of this line they do cooperate with the stack.
  • the shift member 18 is in the lower part of line 18 in the shown position, wherewith the higher part of this line indicates movement toward the left in fig. 1.
  • the hook 19 is in the lower part of the line 19 in the retracted position, that means retracted into pneumatical cylinder 20.
  • the line 20 indicates in its high part the position indicated with 20" of the pneumatical cylinders 20 and in the lower part the position indicated with 20'.
  • stop members 3 move outward and at a predetermined moment, that by way of example has been indicated with an arrow the lowermost object falls down, mostly firstly at one side.
  • the small arrows indicate the moments at which falling downs normally occurs firstly from the stop members 3 and then from the flaps 14.
  • the shift member 18 has returned into its position shown in fig. 1 before the flaps let the object fall down, after completion of the removal of the preceding object.
  • the hooks in their position indicated with 20' can press against the bottom of the box, if this is desired and then will scrape along said bottom during their retracting movement, it may be preferred to chamfer them or round them off at this location in order to prevent damage to the bottom.
  • Such a movement along the bottom will only be necessary when the side walls of the box practically engage the bottom. In that instance it is also possible to shape the foreside of the hooks such like, that they only slide between the side wall and the bottom.
  • the length of the refolded part of the hooks enables the device to work satisfactory with boxes having a somewhat deviating side wall height without need to readjust the apparatus.
  • the side wall may have a considerably lower height before readjustment of the pivot movement of the cylinders 20 or variation of their stroke length is necessary.
  • a further advantage of the invention is, that the same control mechanisms, to wit that for pivoting the cylinders and that for extending and retracting the hooks can be used not only for opening the boxes but also to bring the hooks outside the hopper 1.
