Definitions

  • This invention relates to the forming of cartons, more particularly of paperboard or the like by folding a blank of the type providing a bottom panel, a pair of side panels and a pair of end flaps articulated to the sides of the bottom panel, a pair of major end panels articulated to the upstanding sides of one side panel, a pair of minor end panels articulated to the upstanding sides of the other side panel, the width of the major end panels and the end flaps being substantially the same as the width of the bottom panel, top closure panels on the side panels and major end panels, and a guide tab on each end flap for guiding the end flaps by engagement with the insides of the major end panels during folding, with slits between the end panels and end flaps extending substantially to the meeting point of fold lines between the side panels and the bottom panel and the end flaps.
  • a carton of this type is described in GB-PS 1 424 035 as having the overlying panels bondedto each other by thermoplastic adhesive material on at least one of each pair of t'ie surfaces to be bonded, in particular the end flaps each having an adhesive strip across the full width of the outside thereof adjacent the bottom panel for bonding to the adjacent major end panel.
  • the end flaps have substantially full overlap of the widths of both the major and minor end panels adjacent the juncture with the bottom panel, and the edges of the end flaps contact the fold lines of both major and minor end panels so as to obviate leakage channels.
  • the fold lines are embossed on the blank, with a convexed side of the lines being on the inside of the carton to form beads when folded, the free edge of each major end panel abutting the fold bead for the corresponding minor end panel to assist in forming the side seal of the carton.
  • the slits between the end panels and end flaps must only extend substantially up to the outer limit of the convexed surface of the embossed lines to cause full compression of the convexed surface and whereby puckering of excess paperboard and adhesive caulks the corner formed to obviate pinhole leakage.
  • GB-PS 1 424 035 makes it clear that, in order to turn the blank into a fully formed and fully sealed carton (except that is for the closing and sealing of the closure flaps) ready to receive liquid or semi-liquid products, the blank is coated on both the inside and the outside with thermoplastic adhesive material and a total of eight areas of adhesive are activated by heat applied by complex arrays of nozzle boxes disposed in opposed pairs above a forming die into and through which the blank is moved down (by a plunger or punch) to effect the folding operation.
  • the nozzle boxes also apply heat along a marginal portion of the outside of each major end panel, along the inside of each minor end panel, and across the bottom of the inside of each major end panel.
  • GB-PS 1 424 035 also describes and illustrates how blanks as hereinbefore defined can be cut from flat stock, with adjacent blanks oppositely directed, the major end panel of one being contiguous with the minor end panel of the other and the guide tab of one blank being contiguous to the guide tab of the other blank, whereby to enhance the conservation of paperboard, the full potential of this type of carton has not been realised, probably for a number of reasons.
  • One object of the present invention is to provide a method of forming a carton of the type initially defined applicable to the widest possible range of flat stock; i.e., not limited to stock coated on both sides with thermoplastic adhesive material, and even applicable to thermoplastic (e.g., polypropylene) blanks.
  • thermoplastic e.g., polypropylene
  • Another object of the invention is to provide a method with which adhesive forming the necessary bond between each of at least two pairs of mating surfaces is brought to the best possible condition for the forming operation without impairing the speed with which cartons can be formed.
  • a further object of the invention is to provide a method with which different types of adhesive can be used (to suit different types of stock material and/or coatings and/or impregnations) without impairing the speed with which cartons can be formed.
  • Yet another object of the invention is to provide a machine for forming cartons of the type initially defined and adaptable to the objects as aforesaid.
  • a still further object of the invention is to provide a machine for forming cartons of the type initially defined having readily interchangeable parts facilitating changes in sizes of cartons, and particularly adaptable to a wide range of sizes and capable of forming narrow and deep cartons.
  • a method of forming a carton of the type initially defined comprises the steps of feeding, the blank from a pack onto a conveyor with the side forming the interior of the carton uppermost and the end panels aligned with the direction of travel of the conveyor, passing the blank on the conveyor through an adhesive applying station, applying an adhesive coating within the inside area of each major end panel projecting laterally beyond the respective minor end panel, passing the blank on the conveyor through an adhesive conditioning station, applying heat to the adhesive coatings, feeding the blank from the conveyor onto a die having a throat corresponding substantially to the bottom panel, pushing the blank through the die by means of a plunger engaging the bottom panel, the die having guide surfaces whereby the end flaps and minor end panels are turned inside the major end panels, and applying roller pressure against the major end panels to press them against the minor end panels to cause the adhesive beween them to form an adequate bond to hold the carton together upon being discharged from the die.
  • the total cycle time will be greater (which is of advantage in arranging for the condition of the adhesive to be just right when each blank is pushed through the die), but the speed of forming cartons will be the speed at which the blanks can be fed from the pack to the conveyor or the speed at which the blanks can be fed from the conveyor up to the die.
  • the adhesive may be a water-based adhesive (e.g. polyvinyl acetate emulsion) applied by spraying intermittently in phase with the passing of the major end panels, and then dried by hot air blown thereon as the major end panels pass through the adhesive-conditioning station.
  • a water-based adhesive e.g. polyvinyl acetate emulsion
  • minor end panels are preferably broken upwardly from the plane of the blank as it is fed onto the conveyor, so as to hold the minor end panels clear of the adhesive-applying station (and also ready for folding inside the major end panels), and the end flaps are likewise preferably broken upwardly from the plane of the blank as it is fed onto the conveyor and preferably held over closer to the blank than the minor end panels, even though in the final forming in the die the end panels may be interposed between the respective major and minor end panels. Hot air from the adhesive-conditioning station may also be blown onto the outsides of the minor end panels, to increase the speed at which the bond is formed between the respective major and minor end panels.
  • Suction may be applied through apertures in the vertical edges of the plunger to hold the minor end panels closely thereto, especially the minor end panels of a narrow and deep carton.
  • the control of adhesive condition attainable with the separate adhesive-applying and adhesive-conditioning stations, especially using a water-based adhesive and hot air, is such that this method is applicable to virtually any paperboard capable of being transformed from flat blank to carton in a die, such as, duplex, triplex, solid white, grease resistant, single-sided polythene and double-sided polythene.
  • a method of forming a carton of the type initially defined comprises the steps of feeding the blank from a pack onto a conveyor with the side forming the interior of the carton uppermost and the end panels aligned with the direction of travel of the conveyor, passing the blank on the conveyor through an adhesive activating station, activating adhesive at least within the inside area of each major end panel projecting laterally beyond the respective minor end panel, feeding the blank from the conveyor onto a die having a throat corresponding substantially to the bottom panel, pushing the blank through the die by means of a plunger engaging the bottom panel, the die having guide surfaces whereby the end flaps and minor end panels are turned inside the major end panels, and applying roller pressure against the major end panels to press them against the minor end panels to cause the adhesive between them to form an adequate bond to hold the carton together upon being discharged from the die.
  • the minor end panels are preferably broken upwardly from the plane of the blank as it is fed onto the conveyor, so as to hold the minor end panel clear of the adhesive activating station (and also ready for folding inside the major end panels), and the end flaps are likewise preferably broken upwardly from the plane of the blank as it is fed onto the conveyor and preferably held over closer to the blank than the minor end panels, even though in the final forming in the die the end panels may be interposed between the respective major and minor end panels; however, the adhesive activating station may direct heat (e.g., by means of blown air) in two directions, one downwardly for the insides of the major end panels and one laterally for the outsides of the minor end panels, in which case the breaking of the minor end panels and end flaps and the holding of the end flaps closer to the blank facilitates the application of heat to the minor end panels.
  • the adhesive activating station may direct heat (e.g., by means of blown air) in two directions, one downwardly for the insides of the major end panels and one laterally for the
  • Suction may be applied through apertures ⁇ in the vertical edges of the plunger to hold the minor end panels closely thereto, especially the minor end panels of a narrow and deep carton.
  • a machine for forming cartons of the type initially defined comprises an endless conveyor, a magazine for the blanks inclined downwardly towards the leading end of the upper run of the conveyor, a pick-out and transfer mechanism for feeding the blanks individually in succession from the magazine onto the conveyor with the side forming the interior of the carton uppermost and the end panels aligned with the direction of travel of the conveyor, adhesive-applying and conditioning or activating equipment disposed above the conveyor, a die beyond the trailing end of the upper run of the conveyor and having a throat corresponding substantially to the bottom panel, a transfer mechanism for feeding the blanks in succession from the conveyor onto the die, a plunger for pushing each blank in turn through the die by engaging the bottom panel, the die having guide surfaces whereby the end flaps and minor end panels are turned inside the major end panels, rollers for applying pressure against the major end panels to press them against the minor end panels to cause the adhesivebetween them to form an adequate bond to hold the carton together upon being discharged from the die, a motor, and driving mechanisms connecting
  • the conveyor is preferably provided with pairs of lugs for propelling the blanks positively, and is also preferably provided with guide rails for breaking the minor end panels and end flaps upwardly from the plane of the blanks and for holding the end panels closer to the blanks as they pass the adhesive-applying equipment and adhesive-conditioning or activating equipment, and in readiness for folding the minor end panels and the end flaps inside the major end panels, even though in the final forming in the die the end panels may be interposed between the respective major and minor end panels.
  • Adhesive-applying equipment may comprise sprays applying water-based adhesive intermittently and adhesive-conditioning or activating equipment may comprise hot air blowers operating continuously or intermittently in phase with the passing of blanks along the conveyor.
  • the vertical edges of the plunger may be provided with apertures, with passages through the plunger and flexible pipes to a source of suction, so that suction supplied at the apertures holds the minor end panels of the cartons (especially the minor end panels of narrow and deep cartons) to those edges of the plunger.
  • the magazine and the pick-out and transfer mechanism for feeding the blanks individually in succession from the magazine onto the conveyor can be of conventional type, but the transfer mechanism for feeding the blanks in succession from the conveyor onto the die preferably comprises an endless driven belt having an upper run in extension of the conveyor, and a spring-loaded nip roller adjustable lengthwise of the upper run of the belt, to set the position of the nip between the roller and the belt to cease propelling each blank as the latter moves into its final position on the die.
  • the one motor and driving mechanisms can operate a double (or multiple) machine having pairs (or equivalent numbers) of magazines, conveyors, transfer mecahnisms, dies and plungers side by side, and feeding alternate cartons to a product packaging line, which may be hand-loaded or mechanised loading in a variety of dispositions for a wide variety of products.
  • a further advantage of the methods and machine of the present invention is that, in addition to the saving of flat stock in making the blanks, there are great savings for the user because of savings over a preglued sleeve carton and the flat blanks are more convenient both for shrink-wrapping packs of blanks (instead of having to enclose a lesser number of sleeve blanks in a custom made carton) and loading the magazine.
  • the (or each) conveyor is preferably flanked by longitudinal beams carrying the respective guide rails, adhesive-applying and conditioning or activating equipment spaced longitudinally and projecting laterally appropriately to one size of carton blank, and the (or each) die and plunger are preferably carried together on a common frame, the die and plunger having cross-sectional dimensions and heights appropriate to one size of carton, the longitudinal beams and the frame being readily attachable and detachable, for interchange with similar beams and frames appropriately equipped to suit other sizes of cartons.
  • carton blanks 20 are cut out from flat stock, with adjacent blanks oppositely directed so that the major end panel 21 of one is contiguous to the minor end panel 22 of the other.
  • End flaps 23 are also contiguous but have their mating edges shaped to provide a transition between the major and minor end panels of the repsective blanks.
  • the end flaps 23 of each blank 20 are articulated to the ends of a bottom panel 24, and the major and minor end panels 21, 22 are articulated to the sides of side panels 25, 26 respectively, which are themselves articulated to the sides of the bottom panel.
  • Top side closure panels 27, 28 are articulated on the side panels 25,26 respectively and top end closure panels 29 are articulated on the major end panels 21.
  • Each end flap 23 has a guide tab 30 for guiding the end flaps by engagement with the insides of the major end panels 21 during folding, as shown in Figure 2, and slits between the end panels 21, 22 and the end flaps 23 extend substantially to the meeting point of the fold lines between the side panels 25, 26 and the bottom panel 24 and the end flaps 23.
  • Figure 2 indicates, in accordance with one method of the invention of forming a carton from a paperboard blank as in Figure 1, an adhesive coating 31 applied within the inside area of each major end panel 21 projecting laterally (i.e., in the direction parallel to the length of the bottom panel 24) beyond the respective minor end panel 22, so that upon folding of the blank to bring the side panels 25, 26 parallel to each other with the minor end panels 22 and the. end flaps 23 inside the major end panels 21, the adhesive coatings 31 form bonds between the insides of the major end panels 21 and the outsides of the minor end panels 22, to form the carton shown in Figure 3.
  • Each blank 20 is fed from a pack 32 in a magazine 33 onto a conveyor 34 with the side forming the interior of the carton uppermost and with the end panels 21, 22 aligned with the direction of travel of the conveyor, passing the blank on the conveyor through an adhesive applying station 35 (where the adhesive coating 31 is applied to each major end panel as aforesaid), passing the blank on the conveyor through an adhesive conditioning station.36 (where heat is applied to the adhesive coatings), feeding the blank from the conveyor onto a die 37 having a throat 38 corresponding substantially to the bottom panel 24, pushing the blank through the die by means of a plunger 39 engaging the bottom panel, the die having guide surfaces 40 whereby the end flaps 23 and minor end panels 22 are turned inside the major end panels, and applying roller pressure against the major end panels to press them against the minor end panels to cause the adhesive between them to form an adequate bond to hold the carton together upon being discharged from the die.
  • Figure 4 shows a motor 41 and gearbox 42 and - diagrammatically - driving mechanisms 43, 44, 45, 46, 47 to (respectively) a pick-out and transfer mechanism 48 (of well-known type) for feeding the blanks individually in succession from the magazine 33 onto the conveyor 34, to the conveyor itself, to a transfer mechanism 49 for feeding the blanks in succession from the conveyor onto the die 37, and to the plunger 39.

  • the conveyor 34 comprises two endless chains 50 ( Figure 9) with pairs of lugs 51 for propelling the blanks over a deadplate 52 between the longitudinal beams 53 carrying adhesive-applying and conditioning equipment and guide rails all of which will now be described in greater detail.
  • the minor end panels 22 and the end flaps 23 are broken upwardly from the plane of the blank 20 as it is fed onto the conveyor 34, by means of guide rails 54 ( Figures 5, 6 and 7), so as to hold them clear of the adhesive applying station 35 (and also ready for folding inside the major end panels 21).
  • the adhesive-applying station 35 has adhesive-applying equipment comprising two sprays 55 applying water-based adhesive intermittently in phase with the passing of the major end panels 21, the timing being controlled by a photocell detector 56 carried by one of a pair of guide rails 57, which are spaced from the breaker guide rails 54 by spacer guide rails 58 (which initially receive the major end panels 21).
  • the sprays 55 are adjustable towards and away from each other by means of handwheels or knobs 59 (see also Figure 8).
  • the adhesive-conditioning station 36 is spaced from the adhesive-applying station 35 by guide rails 60 (see also Figure 9) and has adhesive-conditioning equipment comprising two hot air blowers 61 with nozzle boxes 62 having lower apertures 63 for directing hot air onto the adhesive coatings 31 applied to the major end panels 21, and side apertures 64 for directing hot air against the outsides of the minor end panels 22 (see also Figures 10 to 12), while the end flaps 23 are held clear by bar guides 65.
  • the hot air blowers 61 may operate continuously, but if there is an interruption in the succession of blanks 20 sensed by the detector 56, whereupon the hot air is diverted, by diverter valves 66, into upstanding exhaust pipes 67 and ducts 68 ( Figure 4 only) exhausting above an attic 69, which houses a separately powered air unit 70 providing air for the blowers 61 and suction for the pick-out and transfer mechanism 48.
  • Each diverter valve 66 comprises a two-part valve body 71 with alternative passages 72, 73 for the blown air from the blower 61- to respectively the nozzle box 62 and the exhaust pipe 67, under the control of a diverter 74 which is swung between its two positions -( Figures 11 and 12) by an arm 75 oscillated by a pneumatic cylinder 76 and piston 77.
  • the blanks 20 are carried by the conveyor between guides 78 until they are fed by the transfer mechanism 49 onto the die 37.
  • a pair of hold-down guides 79 prevent the blanks from lifting from the conveyor at this crucial stage, and similar pairs of hold-down guides 80, 81 respectively are provided at the adhesive-applying station 35 and between there and the adhesive-conditioning station 36.
  • the transfer mechanism 49 comprises an endless belt 82, driven by the drive mechanism 46, with an upper forwarding run extending from a slot 83 in the end of the deadplate 52 of the conveyor, and with a spring-loaded nip roller 84 adjustable lengthwise of the upper run of the belt to set the position of the nip beween the roller 84 and the belt 82 to cease propelling each blank 20 as the latter moves into its final position on the die 37.
  • the drive mechanism 47 for the plunger 39 includes link rods 85 to a crosshead 86 to which is gimballed the upper end of a shaft 87 to the lower end of which is secured to the plunger 39.
  • the shaft 87 has a non-circular cross- section (e.g., it may be .splined) and slides in corresponding bearings 88 on two out of three cross-beams 89 of a frame 90, so that the plunger 39 cannot rotate about the shaft axis (i.e., the plunger will be maintained in correct alignment with the throat 38 of the die 37).
  • the frame 90 also consists of two columns 91 (between which the cross-beams 89 are secured) and upper and lower pairs of brackets 92, 93 for securing the frame to the end of the machine.

  • the longitudinal beams 53 carrying the respective guide rails 54, 58, 57, 60, 78 and 80, 81, 82, the adhesive-applying equipment 35 and the adhesive-conditioning equipment 36 are provided with brackets 109 ( Figures 5 to 7) with holes 110 locating on pegs 111 upstanding from beams 112 ( Figures 4 and 7), which have quick-action clamps 113 for the brackets, thus enabling the beams 53 to be detached for interchange with similar beams appropriately equipped with guide rails etc. to suit other sizes of cartons.
  • the detector 56, adhesive sprays 55, the diverter valves 66 and the transfer mechanism 49 are conveniently readily transferable from one set of beams 53 to another, to save duplication of too many parts not requiring different dimensions.
  • the frame 90 with its plunger 39 and die 37 are readily detachable from the machine as a unit for interchange with a similar frame appropriately equipped with plunge.rs and dies to suit other sizes of cartons.
  • the adhesive-applying station 35 can be removed, or its sprays 55 rendered inoperative, the adhesive-conditioning station 36 then becoming an adhesive-activating station, with the hot air blown by the blowers 61 activating the thermoplastic or thermosetting adhesive at least within the inside area of each major end panel 21 projecting laterally beyond the respective minor end panel 22 (i.e., the area corresponding to that of the sprayed adhesive coating 31 in Figure 2), or with the hot air softening the surface of a thermoplastic blank within that same area of each major end panel to an extent that enables it to form an adequate bond with the respective minor end panel.
  • the same nozzle boxes 62 may be used, with hot air from the apertures 64 heating the uncoated outside of the minor end panel, or activating thermoplastic or thermosetting adhesive thereon, or softening the surface of a thermoplastic blank additionally on the outside of the minor end panel, to form an extremely good bond with the inside of the major end panel.
  • thermoplastic blanks as well as virtually any paperboard capable of bonding by water-based adhesive conditioned by hot air and also any paperboard carrying or coated - on one or both sides - with thermoplastic or thermosetting adhesive.
  • speed at which cartons can be formed is not restricted to the total cycle time of the operations performed at these steps or stations.
  • the operations requiring most time i.e., the application and conditioning or the activation of the adhesive - or thermoplastic merely take up more length along the conveyor and so do not slow down the rate at which blanks are fed from the pack or the rate at which blanks are pushed through the die.
  • the total cycle time will be greater, but the speed of forming cartons will only be limited by the maximum speedat which blanks can be moved by the conveyor and kept under full control by the various guides,
  • a speed of seventy-five cartons per minute is perfectly feasible with one conveyor, but the comparatively simple nature of the equipment and drive mechanisms associated therewith makes it also very feasible to incorporate two or more similarly equipped conveyors in one machine (with one motor and gearbox, and one air unit) to obtain machine speeds of one hundred and fifty cartons per minute or in excess of two hundred cartons per minute, as may be required for a product packaging line.
