Definitions

  • converting of corrugated boards or blanks into boxes, containers or other three-dimensional forms relied upon a design-conform paradigm wherein the locations of folds, creases, edges and corners for the converted blank were determined without consideration as to the effect on the corrugated board material (as persons skilled in the art well know, dimensional attributes such as caliper were necessarily taken into account).
  • a container for example, was designed in the abstract, e.g., corrugated board size, caliper, stiffness, etc., and a conforming blank was subjected to the converting process without consideration as to the effect that the converting process would have on the corrugated board.
  • scores, slits and slots would be formed in the blank without meaningful concern over the consequences thereof. While such oversight has little consequences for a
  • the resulting folds, creases, corners or edges would often cause compromised outer liner integrity and/or crushed inner liner and fluted mediums in the converted article. This consequence not only decreased structural performance of the article, but significantly reduced the number of reuse cycles. Moreover, because the scores, for example, did not evenly affect the corrugated board, the folds, creases, corners or edges were often uneven, which resulted in unintended flap gaps, fishtails and the like, not to mention overall visual discord.
  • the invention is directed to methods, apparatus, and systems for increasing converting accuracy and consistency of corrugated articles of manufacture such as blanks, intermediates or converted structures to minimize unintended gap variations, fishtail variations and visual discord as well as to minimize unintentional loss of strength due to conversion of such articles.
  • the constitution of converted articles formed from a corrugated board blanks according to the invention comprises at least one intelligently located score, slit or slot (hereinafter collectively "registered modification") based upon knowledge of the corrugated board's fluted medium, including the absolute relative location of at least one fluted medium feature and/or the fluted medium geometry, such as its pitch.
  • methods according to the invention comprise establishing a registered modification using a fluted medium of a corrugated board wherein the registered modification is substantially at a constant distance from a fluted medium feature, such as a peak or a valley, in a direction orthogonal to the flute axis.
  • the modification is said to be in registration with the fluted medium and is referred to herein as a registered modification.
  • the desired registration information can be obtained in many ways including, but not limited to, spatial location knowledge of at least one fluted medium feature and the fluted medium's pitch quality (e.g., frequency and whether constant or variable); or sufficient spatial location knowledge of a plurality of fluted medium features to enable creation of a registered modification.
  • spatial location knowledge of at least one fluted medium feature and the fluted medium's pitch quality e.g., frequency and whether constant or variable
  • sufficient spatial location knowledge of a plurality of fluted medium features to enable creation of a registered modification.
  • at least one visual and/or machine discernible registration indicia can be established on the corrugated board to aid in the creation of future registered modifications.
  • Apparatus and systems according to the invention enable determination of the registration information in one respect, and formation of the registered modification in another respect.
  • registration information of a corrugated board can be obtained, for example, from engineering/manufacturing data about the board and/or inspection of the board (e.g., optical, sonic, thermal, etc.).
  • formation of the registered modification can be accomplished, for example, by CAM/CNC machinery using information obtained in the first respect, or by creation of a registered edge in a corrugated board from which subsequent measurements or determinations for modification locations are made.
  • a registered edge is one that is substantially at a constant displacement from a fluted medium feature, such as a peak or a valley, either of which runs parallel to the flute axis. In this sense, the edge is said to be in registration with the fluted medium and
  • corrugated board possessing a registered edge can be described as edge registered. Once a registered edge has been established, registered modifications can be made to the board simply based upon knowledge of the fluted medium's pitch quality.
  • the invention is further directed to articles resulting from practice of the methods and/or use of the apparatus or systems herein described.
  • such articles may be characterized as edge registered single or multiple wall corrugated board, edge registered single or multiple wall corrugated board blanks or such blanks that have been converted to a finished form.
  • edge registered single or multiple wall corrugated board edge registered single or multiple wall corrugated board blanks or such blanks that have been converted to a finished form.
  • it is not necessary that such articles also have at least one registered modification formed therein; it is only necessary that at least one edge of the article be a registered edge as that term is used herein.
  • a first series of method embodiments of the invention comprises establishing a registered edge in a corrugated board prior to creating any modification of the same.
  • a registered edge which is preferably parallel to the flute direction (alternatively characterized as perpendicular to the presumptive weak axis of the corrugated board)
  • any constant distance there from along the registered edge, and in multiples of the fluted medium's pitch (i.e., period) will encounter substantially consistent mechanical properties of the corrugated board, particularly with respect to the fluted medium.
  • the distance from the registered edge to a flute valley in one direction is "x"
  • the same distance "x" in the same direction anywhere along the registered edge will also terminate along the same flute valley.
  • the registered edge can be established by ascertaining the run length location of a fluted medium feature, for example a most lateral continuous valley, and cross cutting the corrugated board along this fluted medium feature. Since significant fluted medium run-out along the flute axis is rarely encountered in current corrugating production, the resulting edges will form the trailing edge of one corrugated board sheet and the leading edge of another. Furthermore, because there is no meaningful kerf to the cross cutting action, registry among sheets is maintained.
  • a variety of inspection means can be used, which include, but are not limited to, optical emitters and sensors, which detect changes in transmitted or back-scattered light to characterize the corrugated board; sonic transducers, which detect changes in material density and/or caliper of the corrugated board; and thermal emitters and sensors, which detect changes in transmitted or back-scattered heat signatures to characterize the corrugated board.
  • optical emitters and sensors which detect changes in transmitted or back-scattered light to characterize the corrugated board
  • sonic transducers which detect changes in material density and/or caliper of the corrugated board
  • thermal emitters and sensors which detect changes in transmitted or back-scattered heat signatures to characterize the corrugated board.
  • the data can be exploited to guide a trimming tool and/or stage upon which the corrugated board is placed in order to effectuate the desired trimming actions.
  • a flute-based registered edge will have been established.
  • the weak axis direction material constitution can be ascertained by using multiples of the fluted medium's period based from the registered edge. For example, if the fluted medium is a "C" type and has a pitch "P' of 7.6mm (e.g., a peak to peak distance) and if the registered edge corresponds to a flute valley, then "n" multiples of 7.6mm (n x P) as measured from the registered edge will necessarily correspond to a flute valley, which may be a desired location to establish a score. Because the registered edge preferably forms the baseline for all further material modifications, no further examination of the corrugated board is needed.
  • P' of 7.6mm e.g., a peak to peak distance
  • the invention comprises establishing a registered modification in a corrugated board not based upon a registered edge, but based upon the absolute relative location(s) of the fluted medium features.
  • Corrugated sheets are created from a continuous web of combined corrugated board, where a cross cutting knife (cut-off knife) severs the web in register to a predetermined and repeatable point in a single flute. This cut-off operates
  • the board is produced with the running direction at 90 degrees to the flute direction.
  • Each successive sheet is the same as the preceding one.
  • scores, slits, slots, and the like that run parallel to the flutes are positioned accurately to be in register with the flutes.
  • Boxes/containers have scores (for instance) always positioned in the same place relative to the flute individual profile, which will have the effect of producing the same desirable folding effect and accuracy.
  • Score-to-score design panel dimensions will always be multiples of the individual flute pitch employed when making the corrugated board/sheet itself.
  • the folding process collapses the inner liner into the flute valley without crushing the flutes themselves, thereby preserving the essential strength of the corrugated board and making a stronger corner to the container than has been previously possible when non-registering to the flute line/valley (the "in-folded" liner functionally creates an arch or second flute in addition to occupying the flute valley, thereby providing dual means for enhancing corner strength).
  • Registering these parallel-to-flute-valley converting considerations also enhances the repeatable assembled accuracy and appearance of finished containers, also an attribute missing when non-registered conversion operations are carried out.
  • Pseudo-radiused corners are corner pairs or triplets that permit adjacent or proximately located corners or folds to mimic high degree corners or folds, that otherwise may compromise the structural integrity of the resulting converted article.
  • proximately located corners or folds are in-folds that are low pitch multiples from each other, e.g., 1 , 2 or 3 flute periods or specifically, valleys. For example, a pair of adjacent or proximately located 45° corners or folds mimic a 90° corner; a triplet of 30° folds also mimic a 90° corner.
  • the invention and its embodiments also provide opportunities for enhancing the performance of multiple wall corrugated board: by creating multiple wall corrugated board wherein the fluted mediums are registered with each other (such as when similar pitch mediums are used) or choosing pitch multiples that registration still occurs even when differing pitches are used, the benefits of the invention such as increased accuracy and consistency as well as minimized loss of strength during conversion processes can be achieved.
  • articles within the scope of the invention set forth herein include at least one registered edge or at least one registered modification resulting from the practice of at least one method aspect of the present invention.
  • Articles may, and desirable do, comprise both at least one registered edge and one registered modification.
  • articles comprise single or multiple wall corrugated board, corrugated board blanks and/or converted corrugated boards such as containers, boxes, displays, or any other three-dimensional corrugated structure resulting from a converting process.
