Definitions

  • a packaging machine for securing a wrappertype blank about a group of articles is provided with a continuously movable tucking stud mounted on an endless conveyor element whose working reach is disposed alongside the path of movement of a group of articles and an associated blank, said stud being engageable with a pair of article retaining and blank reinforcing flaps so as to fold such flaps inwardly of the blank to positions of enveloping relationship relative to an article.
  • Guides are arranged so as to complete the folding of the blank in such manner as to force the flapsinto secure article gripping relationship relative to the article and thereafter the ends of the blank are folded underneath the group of articles and secured together.
  • the machine and method of this invention are concerned with the inward folding of pairs of flaps cut from the corners of an open-ended tubular wrapper to define article receiving apertures.
  • the two flaps of each pair of flaps are engaged initially and folded inwardly while the adjacent portions of the blank are held against substantial sidewise movement by suitable guide means.
  • the guide means folds the flaps and the associated portions of the blank inwardly toward the articles comprising the particular article group to positions where the spaced flaps of each pair of flaps engage and receive a part of an article.
  • the folding operation is completed so as to force the pairs of flaps into snug article gripping relationship and the end portions of the blank are secured together, all such operations being performed while the article group and its associated blank are moved continuously along a predetermined path.
  • FIG. 1 is a schematic side view of a packaging machine of the type to which this invention is applicable;
  • FIG. 2 is a perspective view of a package formed by the machine of FIG. 1;
  • FIG. 3 is a plan view of a blank from which the package of FIG. 2 is formed;
  • FIG. 4 is an enlarged view taken along the line designated 44 in FIG. 1 and constitutes a plan view of the mechanism constructed according to this invention;
  • FIG. 5 is a front view of the mechanism depicted in FIG. 4, and in which FIG. 6 is an end view taken along the line designated 6-6 in FIG. 5.
  • the numeral 1 generally designates the top panel of the carrier. It will be understood that this panel is designated as the top panel for the sake of convenience and that this panel could constitute the bottom panel depending on the orientation of the finished package.
  • Formed in the top panel I for engaging the recessed ends of the packaged cans are the tabs 2, 3, 4 and 5. These tabs are foldably secured to the top panel by fold lines designated respectively at 6, 7, 8 and 9.
  • the tabs 2-5 are simply folded downwardly and inwardly approximately 180 so that. an abutment ledge is formed for engaging the upwardly protruding chime of the end cans thereby to secure the cans against dislodgmentthrough the open ends of the package.
  • separator tabs l0, l1 and 12 are struck from the top panel 1 and are foldably joined thereto along their respective fold lines 13, 14 and 15. Separator tabs -12 are simply folded inwardly approximately 90 and are interposed between the cans as is well known.
  • finger gripping tabs 16 and 17 are struck from top panel 1 and are foldably joined thereto along fold lines 18 and 19 respectively.
  • the sidewalls 20 and 21 are foldably joined to the side edges of top panel I along fold lines 22 and 23 respectively.
  • Bottom panel 24 is foldably joined along fold line 25 to the bottom edge of sidewall 20 while bottom panel 26 is foldably joined along fold line 27 to the bottom edge of sidewall 21.
  • the locking tabs 28-31 are driven through the openings defined by retaining tabs 32-35 respectively in a manner well known in the art.
  • the bottom portions of the packaged cans in one row are separated from the bottom portions of the cans in the other row by the medial separator panel 36 which is foldably joined to bottom panel 24 along fold line 37 in a manner well known in the art.
  • a pull tab 38 is formed in one of the sidewalls such as 21 and cooperates with a plurality of cuts generally designated by the numeral 39 so that a pull exerted on tab 38 effectively tears the sidewall 21 and renders the packaged items C readily accessible to the ultimate user.
  • tightening apertures are formed in-the bottom panels 24 and 26. These tightening apertures receive machine elements which are manipulated so as to perform the desired tightening operation in a manner well known .in the art.
  • the tightening apertures designated generally by the numerals 40-42 in the bottom panel 24 and the apertures designated by the numerals 43-45 in bottom panel 26 are provided with reinforcing flaps. These flaps are designated by the numerals 46-57 in FIG. 4. Reinforcing flap 46 is struck from the bottom panel 24 and is foldably joined thereto along fold line 58 while reinforcing flap 47 is struck from bottom panel 24 and is foldably joined thereto along the fold line 59. In like fashion, the remaining reinforcing flaps 48-57 are foldably joined to their associatedbottom panels. Thus when machine elements enter the tightening'apertures the reinforcing flaps such as 46 and 47 are swung inwardly and serve as strengthening means along the edges of the tightening apertures.
  • supplementary flaps 60-65 are formed in the lower portion of sidewall 20 and similar supplementary flaps 66-71 are formed in the lower portion of sidewall 21.
  • Supplementary flap such as 60 is foldably joined to sidewall 20 along fold line 72 and to the adjacent end edge of main reinforcing flap 46 by fold line 73 which is aligned with fold line 25.
  • supplementary flaps 61-65 are foldably joined to the sidewall 20 and to their associated main reinforcing flaps while supplementary reinforcing flaps 66-71 are foldably joined to sidewall 21 and to their associated main reinforcing flaps.
  • the main and supplementary flaps are folded inwardly so that the flaps appear as indicated for example at 45 in FIG. 2.
  • the tightening aperture generally designated by the numeral 41 is defined by hinge lines 74 and 75 by which the main reinforcing flaps 48 and 49 are adjoined to the bottom panel 24.
  • these hinge lines 74 and 75 converge in the direction of tightening movement of the tightening element, i.e., away from the sidewall 20 and toward the medial line of the carrier.
  • fold lines 74 and 75 are disposed in diverging relation in the direction of sidewall 20.
  • the can C rests atop the main reinforcing flaps 48 and 49 as will be readily understood particularly from FIG. 2.
  • the supplementary reinforcing flaps such as 62 and 63 are struck from the lower portion of sidewall 20 and are foldably joined to the main reinforcing flaps 48 and 49 respectively by fold lines 76 and 77 as can best be seen from FIG. 3.
  • Supplementary reinforcing flap 62 is foldably joined to sidewall 20 along fold line 78 while reinforcing flap 63 is foldably joined to sidewall 20 along fold line 79 as is best shown in FIG. 3.
  • fold lines 76 and 77 which interconnect the main and supplementary reinforcing flaps 48, 62, and 49, 63 are aligned both with each other and with the fold'line 25 interconnecting sidewall 20 and bottom panel 24.
  • the machine and method of this invention are designed for manipulating the flaps 46-57 and 60-71 into positions of enveloping relationship relative to the packaged articles.
  • the machine comprises a schematically represented base designated by the numeral 80, schematically represented hopper 81 in which a stack of blanks B is disposed.
  • Articles to be packaged are designated at C and move along through the machine in the direction by the arrow 82 from left to right and during movement through the machine, blanks disposed atop article groups such as are indicated at Gl-G4 are held above the associated article group by suitable conventional holddown mechanism generally designated by the numeral 83.
  • the mechanism 84 schematically represented in FIG. 1 is mounted alongside the machine frame 80.
  • mechanism 84 as shown in FIG. 1 is for the purpose of manipulating the flaps on one side only of the carrier. It will be understood of course that similar mechanism is mounted on the opposite side of the machine and serves to manipulate the flaps on the opposite side of the carton.
  • the flap manipulating mechanism 84 comprises a base plate 85 mounted on adjustable support elements 86, 87 and 88.
  • An endless conveyor chain 89 is trained about a plurality of sprockets 90, 91, 92 and 93.
  • Endless element 89 is driven through gearbox 94 which in turn is driven by a sprocket 95 and driving chain 96 from a driving element not shown in the drawing but which is conventional and synchronized with the operations of the packaging machine itself.
  • Sprocket 93 is a laterally adjustable idler sprocket which may be employed to control the tension of endless element 89.
  • Sprocket 91 is utilized to dispose the trailing portion 97 of the working reach of endless element 89 disposed between sprockets 90 and 91 in a converging relationship relative to the path of movement of the articles C as they move from left to right.
  • the flaps of the carton are manipulated by tucking studs mounted on endless element 89 and designated by the numerals 99, 100, 101, 102 and 103.
  • the tucking studs are shown along the working reach only of endless element 89 for the sake of clarity and convenience although it will be understood that these studs are disposed about the entire length of the endless element 89 and that the studs are spaced apart by a distance which corresponds to the spacing between the pairs of flaps in the carton and also in such manner as to accommodate the particular spacing between article groups.
