Definitions

  • Folded and glued paperboard "lockbottom” or “autobottom” cartons are generally flat as produced, but are characterized by having one edge portion that is much thicker than the opposite edge portion.
  • the thicker edge portion (which normally forms the bottom part of the carton, when erected) consists of multiple plies (typically five) of the construction material, whereas the thinner edge portion (which normally comprises the cover) is typically of only one- or two-ply thickness.
  • the resulting batch is of wedge-like form.
  • lockbottom cartons are conventionally loaded into shipping cases as alternating batches of a multiplicity of cartons, arranged in opposite directions with the thicker end of one batch mated with, or complementary to, the thinner end of the adjacent batch. Doing so serves of course to most efficiently utilize the capacity of the shipping case while, at the same time, affording uniform weight distribution.
  • the systems for handling and loading such collapsed cartons are usually operatively connected directly to the machines by which they are folded and glued, from which they are presented as a shingled stream in which the thicker end portion of each carton is disposed as the leading edge with respect to the machine travel direction.
  • the packaging machines are also designed to handle cartons so oriented.
  • each carton is designated "C”

  • B the alternating batches of cartons (in this instance, consisting of five cartons)
  • B' the corrugated shipping case (shown in broken line) contains a count of 60 cartons and is designated S.
  • An individual carton C is also shown in Figure 2, and a stacked batch B often cartons is shown in Figure 3.
  • the upwardly facing side of the carton is discontinuous, being comprised of panels that lie in at least two parallel planes and that present a free, generally transverse intermediate edge E at the intersection of the planes.
  • the leading edge of a successive carton will have a tendency to catch on, or interlock with, the exposed intermediate edge structure E of the underlying carton, as indicated by the three triangular marks in Figure 4, usually necessitating stoppage of the entire production line when that occurs.
  • a more specific object of the invention is to provide such a transporting system in which conveying means functions to invert articles transported thereby so that they all arrive at a common accumulation location with a substantially continuous side of each article facing upwardly.
  • Another broad object of the invention is to provide a method for automatically merging and accumulating articles, of the construction described, whereby alternating groups of the articles are delivered to an accu- mulation location inverted end-to-end but with a substantially continuous side of each article facing upwardly.
  • the word “article” refers to any object that is generally flat and that has the end portion and intermediate edge structure characteris- tics broadly described.
  • An “article” will usually take the form of a lockbot- tom carton or the like, but other such objects (e.g., packages having receptacle components attached near one end of a backing board) are also contemplated.
  • An assemblage of a plurality of articles having the same orientation is referred to herein as a "batch,” whereas the term “group” more broadly refers to a plurality of articles having such orientation but arranged either as a batch or as a consecutive sequence of individual articles.
  • a transporting system for use in a packaging machine, for automatically merging and accumulating substantially identical, generally flat articles of the kind described, comprising first and second conveying means constructed for transporting the articles along separate paths from a common entrance location of the machine, at which all of the articles have the same, upwardly facing orientation, to a common accumulation location, the conveying means being so constructed as to maintain the articles transported with their endwise axes in alignment with the axis of travel.
  • the first conveying means is so constructed and arranged as to deliver the articles to the accumulation location with the original orientation
  • the second conveying means is so constructed and arranged as to deliver the articles to the accumulation location with an orientation in which they are inverted from the original orientation, end-to- end about transverse axes thereof
  • the first and second conveying means delivering the articles transported thereby to generally opposite sides of an upwardly facing support surface present at the accumulation location, for merging and accumulation, usually as a shingled stream.
  • the machine also has diverting means at the entrance location, for presenting equal numbers of articles, as groups, alternatingly to the first and second conveying means for transport thereby.
  • the second conveying means includes a portion that is so constructed as to invert the transported articles, from one side to the other about their endwise axes, so that, at the accumulation location, the substantially continuous sides of the articles face upwardly.
  • the inverting portion of the second conveying means is constructed to twist through an effective angle of substantially 180° about the axis of travel.
  • the second conveying means may include at least three cooperating, separate sections, with the portion for inverting the articles comprising a section that is interposed between two others.
  • the inverting section will preferably comprise at least one belt, assembled with support means that disposes two portions of the belt closely adjacent to one another for capturing the articles therebetween and for together traversing the two other sections; the inverting conveyor section will desirably comprise a single, endless belt.
  • first conveying means will follow a path that has a substantial portion disposed above the level of the entrance location and the accumulation location (both elevated, but not necessarily at the same height) and the second conveying means will follow a path that has a substantial portion disposed therebelow.
  • the travel axes of the first and second conveying means will normally be disposed substantially on a common vertical plane.
  • the machine will usually also include third conveying means disposed at the article-accumulation location and having a travel axis with a horizontal portion that extends substantially normal to the above-mentioned common vertical plane.
  • the third conveying means will preferably provide the up- wardly facing support surface on which the delivered articles are accumulated such that, with all of the conveying means in operation in appropriately timed relationships, the articles accumulate as a shingled stream, of alternating batches, on the support surface (generally, a belt or apron).
  • the terminal ends of the first and second conveying means will normally exit at the accumulation location at a level somewhat above the support surface, so that, upon exiting from the conveying means, the articles drop upon the support surface.
  • the exits, or outlets, of the conveying means will usually also be so disposed that, as delivered, the leading end portions of the transported articles extend beyond lateral margins of the support surface, and over the proximal end portions of previously deposited articles, before they are released.
  • the machine will additionally include a hold-down mechanism comprised of at least first and second contact members disposed, respectively, adjacent the generally opposite sides of the support surface at the common accumulation location.
  • the hold-down mechanism will be constructed for moving the contact members, in alternating sequence, between a position proximate the support surface, for bearing upon the end portion of a deposited article, and a posi- tion displaced from the support surface for permitting the articles transported by presently discharging conveying means to exit therefrom, unimpeded.
  • each of the contact members will desirably comprise at least one brush, typically mounted for pivotal movement between the proximate and displaced positions.
  • the method broadly comprises the steps: providing a multiplicity of articles at a common entrance location, all of the articles having the same, first orientation, taken end-to-end and also side-to-side, with a substantially continuous side facing generally upwardly; delivering, by first conveying means, first groups of a plurality of the articles to one lateral side of an upwardly facing support surface, at a com- mon accumulation location, with the articles having the first orientation; delivering, by second conveying means, second groups of an equal number plurality of the articles to a generally opposite lateral side of the upwardly facing support surface at the accumulation location, with the articles having a second orientation in which they are reversed from the original orientation only end-to-end about their transverse axes and not reversed side-to-side about endwise axes thereof, deliveries of the groups of articles being so timed that a first group of the articles alternates with a second group, and that batches of articles merge and accumulate, usually as a shingled stream, so that, at the accumulation location, the discontinuous sides of all of
  • the method of the invention will include a step of inverting the articles of the second groups, by use of the second conveying means, from one side to the other about endwise axes thereof.
  • the articles employed in the method will usually be in the form of collapsed lockbottom folded cartons, or the like, in which the transversely extending thicker end portion is of multiply construction and constitutes the leading edge as the cartons are transported by the conveying means.
  • the opposite, transversely extending thinner end portion (the trailing edge) will usually be of single-ply construction, or occasionally of double-play construction, and the leading edge:trailing edge thickness ratio will typically be 5:1 or 5:2, respectively.
  • That individual cartons arrive consecutively at a merge point at the terminal, exit ends of the two conveyors, at which is provided a third conveyor that runs perpendicular to the x-axis plane (as is also more fully dis- cussed below).
  • That y-axis conveyor operates at a controlled, variable speed and at a selected ratio to the x-axis conveyors (always more slowly); it serves for off-loading of the shingled stream of cartons, generally for deposit into a transport container (for which purpose the conveyor may have a z-axis portion as well).
