• FIGURE 10 is a schematic perspective view of a packaged carton produced using the machinery of Figures 1 to 9.
• FIG. 1 there is shown a packaging machine 10 according to the invention.
• the machine takes an incoming feed of articles such as cans of drinks and divides these into upper and lower feed paths.
• a divider panel, or insert is added to arrays of articles in the lower feed path and then the panel is manipulated to ensure that deformable portions of the divider panel are properly nested with the tops of articles.
• the upper layer of articles is then stacked on top of the divider panel in register with a lower article such that the bottom of an upper article nests in the deformable portion of the divider panel which is nested in the upper part of the lower article.
• the stacked, divided, double layer of articles are then packaged in a carton, which in this example is of the wraparound type.
• the divider panel 13 also ensures that the tops and bottoms of adjacent articles do not rub against one another in a packaged carton which would otherwise create unsightly marking of the ends of at least one of the articles.
• the articles A are made of aluminum
• constant rubbing of adjacent ends of stacked articles can lead to an unsightly deposit containing aluminum oxide, on one of the ends.
• movement of the articles can lead to damage to the ends of the articles, including to ring pulls at the end of a can.
• a feeder mechanism 16 draws divider panels, or inserts, 13 from a hopper 12, which in this example comprises an extension feature 14 for holding a large number of inserts 13.
• the feeder mechanism 16 may comprise vacuum cups for example which pick up the front divider panel 13 from the hopper and transport it to a position adjacent the tops of articles A in lower rows 38.
• the divider panels 13 comprise lateral recesses 60 which enable the panel to be carried by lug chains 42 provided adjacent the tops of articles A on each side of the rows 38.
• lug chains 42 provided adjacent the tops of articles A on each side of the rows 38.
• the arrays of articles and the divider panel are then conveyed along the lower feed path to an insert clipping wheel 18 which causes locking tabs 64 defined in insert 13 to be forced out of the plane of the divider panel such that they wedge between the tops of adjacent articles in the lower array.
• the articles A are cans which have an upper rim R which is of lesser diameter than the main body diameter of the substantially cylindrical cans.
• the locking tabs 64 can therefore be positioned in the gap between rims of adjacent articles thereby to hold the divider panel 13 in place during movement of the lower array of articles.
• Insert clipping device 18 is shown in greater detail in Figure 6 which shows that the device comprises a cylindrical wheel 74 which is driven by means not shown to cause radially extending figures 70 to rotate about the central axis of wheel 74.
• the shaped end portion 72 of a finger 70 abuts the upper surface of a locking tab 64 of divider panel 13 as the fingers rotate to a lowermost position.
• the end portions 72 can be rounded to enable easy entry and exit of the fingers from the apertures surrounding tab 64 in the divider panel 13.
• the punch wheel comprises a cylindrical wheel 84 which is driven about its cylindrical axis by a means not shown.
• the cylindrical surface of wheel 84 comprises two rows of hollow cylindrical cups 80 which each have a rim 82 to simulate the base of an article.
• the movement of punch wheel 20 is again synchronised with the movement of the lower arrays of articles and divider panels such that individual cups 80 cause the deformable portion 62 in panels 30 to deform and thus nest in the top of the article A.
• the articles comprise an upper end which is longitudinally recessed with a respect to upper rim R.
• the deformable portion 62 provides a cup ⁇ like structure between the rim R and the end of an article. This arrangement is shown in Figure 4.
• the divider panel 13 can be held in place on a lower array of articles due to the effects of one or both of the tabs 64 and the deformable portion 62.
• lug chains 42 can still engage recesses 60 thereby ensuring that individual divider panels 13 are accurately positioned with respect to an array of articles.
• FIG. 1 An upper array of articles is now created ready to be stacked on top of an array such as shown in Figure 4.
• two upper rows 44 of articles are conveyed along conveyors 22.
• the rows can be guided by fixed rails not shown in the attached drawings.
• the flow of a row of articles 44 can be regulated by a star wheel 46.
• the rows 44 are brought together over a dividing plate 91.
• the movement of both the upper and lower arrays of articles is then regulated by a device 48 shown more clearly in Figure 9.
• regulator 48 which effects the stacking of an upper and lower pair of articles comprises a pair of star wheels 90 and 92.
• the star wheels comprise a series of toothed plates 94.
• the plates 94 comprise recesses 98 separated by teeth 96 which acts to engage part of the circumference of an article.
• a lower and upper set of plates is provided to engage lower and upper articles.
• the upper and lower sets of plates are separated by a gap 99 to allow for dividing plate 91.
• aligned recesses in the upper and lower sets of plates 94 effect an alignment of an upper and lower article such that as the star wheel 90 or 92 rotates it provides an effective chute through which an upper article falls under gravity into the cup defined by deformable portion 62 in the top of the lower article.
• a stacked array as shown in Figure 5 is created.
• the number of articles in a stacked group can be anything from a stacked pair, three or four stacked articles and so on.
• the arrays can of course comprise any number of rows.
• the stacked array can be conveyed as a unit, for example, using a conventional conveyor beneath the lower array of articles, to a carton loading station.
• machine 10 comprises a hopper 24 for a stack of cartons 26.
• An individual carton 100 can be withdrawn from the front of the stack 26 using a feeder mechanism 28 similar to mechanism 16 described earlier.
• a carton 100 can thus be moved from hopper 24 to a feed chain 30 which can comprise lugs for example which engage cooperating parts of the carton to enable it to be conveyed to an overhead boom chain 34.
• a device initially presses the top panel 110 of the carton against the upper ends of the upper articles.
• the sides 114 and 124 of the carton 100 are then folded downwardly using folding wheel 32.
• the sides of the cartons are then guided by a carton side lug chain 52 along to an article heel expander device 54 which causes known article heel engaging devices 104, provided by the carton, to be expanded prior to pressing the sides of the carton 114 and 124 against the sides of the array of stacked articles.
• Boom chain 34 continues to press the top of the carton against the array of articles whilst a known locking mechanism 56 effects the folding of heel panels 116 and 122 and base panel portion 118 and 120 about the underside of the stacked array of articles.
• the base panel portions may be glued.
