Abstract

Abstract A method and apparatus for assembling flats for folded boxes into a container for shipment and storage which comprises the steps of positioning a container under an opening having a slidable closure which is in a closed position, positioning a sheet of divider material over the slidable closure, positioning a plurality of stacked flats on top of the divider material in a defined space, applying a weight to the stack flats, cutting the divider material to size, opening the slidable closure and dropping the divider material, flats and weight into the container and thereafter removing the weight.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 199 words
A device for packaging folded box flats comprising: a frame member, a first surface associated with said frame member for receiving a container thereon, a second surface carried by said frame member positioned vertically above the said first surface, said second surface including a movable surface portion, means for moving the surface portion to and from an area over a container on the first surface, vertical walls defining an area above said second surface, means for positioning a sheet of divider material on said movable surface portion, means for positioning packets of a plurality of individual box flats on said sheet of divider material, a movable weight positionable at a first position on said packets, means allowing said weight to freely fall from said first position to a second position adjacent the first surface, means limiting movement of said weight in a horizontal direction whereby when said movable surface portion is removed from said area, the divider material, packets and weight will fall towards the first surface, means restricting spreading of the individual flats during falling to maintain the position and alignment of the packets, and means for moving said weight to a third position above the second surface.
Claim 2
Independent Claim 199 words
A device for packaging folded box flats comprising: a frame member, a first surface associated with said frame member for receiving a container thereon, a second surface carried by said frame member positioned vertically above the said first surface, said second surface including a movable surface portion, means for moving the surface portion to and from an area over a container on the first surface, vertical walls defining an area above said second surface, means for positioning a sheet of divider material on said movable surface portion, means for positioning packets of a plurality of individual box flats on said sheet of divider material, a movable weight positionable at a first position on said packets, means allowing said weight to freely fall from said first position to a second position adjacent the first surface, means limiting movement of said weight in a horizontal direction whereby when said movable surface portion is removed from said area, the divider material, packets and weight will fall towards the first surface, means restricting spreading of the individual flats during falling to maintain the position and alignment of the packets, and means for moving said weight to a third position above the second surface.
Claim 3
Independent Claim 127 words
The method of inserting packets of folded box flats in a container which comprises the steps of positioning a container under an opening having a slidable closure, positioning the slidable closure in a closed position, positioning a sheet of divider material on top of the slidable closure remote from the container, positioning packets of flats on the divider material over the slidable closure, positioning a weight on said packets, opening said slidable closure and dropping said divider material, packets and weights into said container, restricting spreading of the box flats during movement of the packets and weight from the area of the opened closure to the container, and thereafter removing said weight from said container to a position above said slidable closure and closing said slidable closure.
Claim 4
Independent Claim 127 words
The method of inserting packets of folded box flats in a container which comprises the steps of positioning a container under an opening having a slidable closure, positioning the slidable closure in a closed position, positioning a sheet of divider material on top of the slidable closure remote from the container, positioning packets of flats on the divider material over the slidable closure, positioning a weight on said packets, opening said slidable closure and dropping said divider material, packets and weights into said container, restricting spreading of the box flats during movement of the packets and weight from the area of the opened closure to the container, and thereafter removing said weight from said container to a position above said slidable closure and closing said slidable closure.
Claim 5
Independent Claim 154 words
A device for packaging box flats in a container which comprises a frame device, a first surface associated with said frame device for receiving a container, a second surface carried by said frame device, portions of said second surface being movable to provide an opening in said second surface above a container received on said first surface, vertical walls extending above said second surface defining an area which includes the opening, a movable weight movable from a position above said second surface to a position adjacent said first surface, a plurality of vertical grooves in at least some of said vertical walls, a plurality of shoulders on the periphery of said weight indexible with said grooves, and means for guiding and controlling movement of the weight, the shoulders on the weight having outside end portions thereof which project below a bottom surface of said weight, the bottom surface being parallel with the second surface.
Claim 6
Independent Claim 154 words
A device for packaging box flats in a container which comprises a frame device, a first surface associated with said frame device for receiving a container, a second surface carried by said frame device, portions of said second surface being movable to provide an opening in said second surface above a container received on said first surface, vertical walls extending above said second surface defining an area which includes the opening, a movable weight movable from a position above said second surface to a position adjacent said first surface, a plurality of vertical grooves in at least some of said vertical walls, a plurality of shoulders on the periphery of said weight indexible with said grooves, and means for guiding and controlling movement of the weight, the shoulders on the weight having outside end portions thereof which project below a bottom surface of said weight, the bottom surface being parallel with the second surface.
Claim 7
Dependent Claim 28 words
The device of claim 3 wherein the weight comprises a perforated plate fixed to the lower end of at least one vertical member guided in a guiding means.
Claim 8
Dependent Claim 39 words
The device of claim 4, wherein the said weight comprises an assembly of telescopic parts whereby the horizontal dimensions of the weight are variable, the weight being affixed to at least one vertical bar guided in a guiding means.
