Definitions

  • This invention relates to packaging of primary articles such as cans and bottles into multiple pack cartons, and is more particularly concerned with feeding such cartons in collapsed condition from a hopper and then initiating and completing a set up operation of cartons in sequence.
  • UK Patent 205 3133 to Bosch concerns an apparatus for removing, folding box blanks from a stationary magazine and erecting and transferring the blanks. It comprises such members which are mounted on four point linkages and arranged on a rotary carrier controlled by cams. During the rotation to facilitate the removal of the blanks from a stationary condition activation of the suction members occurs. During the transfer cf the erected blanks to the transport device, suction members are moved synchronously with the transport device.
  • WO 92/15450 to Mead Corporation illustrates a carton set up machine having a suction device for withdrawing collapsed sleeve type cartons from a magazine.
  • the suction device moves inwardly and outwardly on a slidable rod as it orbits about a central rotating shaft.
  • An oscillating gripper mounted outside the orbit of the suction device pulls outwardly on an outer panel of the collapsed carton to begin opening it.
  • the present invention can be used with a packaging machine and it is envisaged that it can be used on various other types of packaging machinery.
  • the erecting mechanism of the present invention can be sold as an individual module to be fitted to new equipment or to existing equipment on a retro-fit basis.
  • an apparatus for separating opposed first and second panels of a carton blank being conveyed through a packaging machine comprising a first panel separating means arranged to move around a pre-determined locus such that the panel separating means comes into contact with and engages said first panel.
  • the apparatus is operable to change the velocity of the first panel separating means relative the carton during engagement with the first panel so as to move the first panel away from the second panel.
  • the apparatus may further comprise second panel separating means arranged to move around a second pre-determined locus such that the second panel separating means comes into contact with and engages the second panel, the apparatus being further operable to change the velocity of the second panel separating means during engagement with the second panel thereby to separate the second panel from the remaining panels of the carton.
  • control means may be arranged to control the speed of the or each panel separating means.
  • control means may vary the speed of the or each panel separating means to lie within the range of plus or minus 1 to 25% of the speed ofthe cartons being conveyed.
  • the or each panel separating means may comprise a suction cup and cupholder mounted to a shaft which rotates about a fixed axis, the suction cup being connected to a vacuum supply during the panel separation.
  • the first panel separating means may be accelerated with respect to the carton blank to cause the first panel to advance relative the blank.
  • the panel separating means may be decelerated with respect to the carton blank to cause the first panel to retreat relative the blank.
  • the second panel separating means may be decelerated with respect to the carton blank to cause the second panel to retreat relative the blank.
  • a second aspect of the invention provides a device for setting up carton blanks in a packaging machine which device comprises first and second opening wheel being oppositely disposed.
  • the wheels are each provided with panel separating means to retain opposed portions of the blank and wherein control means is provided to accelerate the first opening wheel relative to the second wheel and/or control means is provided to decelerate the second opening wheel relative to the first wheel.
  • the acceleration and/or deceleration of respective first and second opening wheels cause the opposed portions of the blank to be moved apart.
  • the first and second panels may comprise opposite side walls of a carton blank.
  • a third aspect of the invention provides a method for separating opposed first and second panels of a carton blank conveyed through a packaging machine, which method comprises the steps: (i) introducing the carton blank and conveying it through the packaging machine; (ii) moving a panel separating means to bring it into contact with the first panel to be engaged therewith; (iii) changing the velocity of the panel separating means relative the carton blank to cause the first panel to be moved away from the second panel; and (iv) disengaging the panel separating means from the first panel.
  • step (iii) the panel separating means may be accelerated with respect to the carton blank to cause the first panel to advance relative the blank.
  • step (iii) the panel separating means may be decelerated with respect to the carton blank to cause the first panel to retreat relative the blank
  • FIGURE 7 is a perspective view of a second embodiment of the panel separating means of the invention.
  • carton 10 is a basket type carrier, shown in Figure 1b in a set up condition ready for lowering onto articles.
  • the carton 10 includes opposed side wall panels 12, 14 and opposed end wall panels 16, 18 hingably connected one to the next.
  • the carton 10 further includes a handle structure 20 which interconnects end wall panels 16, 18 and comprises transverse partition panels 22 interconnecting each side wall panel 12, 14.
  • Base panels 24, 26 are hingably connected to each side wall panel 12, 14 respectively.
  • cartons can vary depending upon the shape and/or quantity of articles to be packaged and accordingly, a machine in accordance with the present invention is adjustable in numerous respects so that it can process a wide variety of such cartons.
  • the principal arrangements which are likely to be varied are shown in Figure 1a in which "H” is the overall height of the set up carton equivalent to the distance between the upper edge of the side wall and base panel, "L” is the overall length of the carton when the base panels are closed.
  • H is the overall height of the set up carton equivalent to the distance between the upper edge of the side wall and base panel
  • L is the overall length of the carton when the base panels are closed.
  • suitable adjustment for example wraparound or end loading cartons. Any reference in this specification to carton type includes different sizes of a particular carton style.
  • FIG. 2 of the drawings there is shown a machine 50 for processing cartons 10, 52 of the basket type outlined above.
  • the upstream end of the machine includes a hopper 54 in which a multiplicity of cartons 10, 52 in flat collapsed condition are held ready for processing.
  • the cartons are removed from the hopper 54 sequentially by a rotary vacuum feeder 56.
  • Figure 3 illustrates the path of a carton in flat collapsed condition which is removed from the hopper 54 and is rotated by the vacuum feeder 56 to the infeed end of the machine 64.
  • the blank is placed between the nip end 66 of an infeed belt set shown generally at 68.
  • the infeed belt set includes pairs of upper and lower receiving belts 70, 72 spaced apart so as to receive in this embodiment the handle portion 20 and base panels 24, 26 of a flat carton delivered by the rotary feeder 56.
  • the belt sets 70, 72 maintain the position of the carton and move the carton downstream to the set up station shown generally at 74.
  • the apparatus of the present invention is used to separate opposing panels and to assist in partly erecting the carton.
  • panel separating means or opposed opening wheel units
  • 76, 78 are positioned either side of the carton feed path of which the nearside panel separating means 76 is adjustable relative to the far side panel separating means 78 transversely to the machine to reflect the adjustments made according to the type of carton.
  • the panel separating means are similar and hence only nearside means 76 is described in detail with reference to Figures 4, 6a and 6b.
  • the panel separating means 76 comprises a vacuum suction cup 79 connected via a drive rod 80 to a drive shaft 82, rotatable about a fixed axis.
  • the drive shaft 82 is preferably powered by a servo motor 84.
  • the shaft 82 is generally supported at its end by a suitable bearing structure but which is conventional and which is mounted to a side frame.
  • the servo motor 84 is controlled by suitable control means which can cause the rotational velocity of the panel separating means 76 to vary and, therefore, causes the velocity of the suction cup 79 to vary.
  • the drive rod 80 is preferably connected to a cam track by a cam follower (not shown) contained in a housing 86 or to other suitable means to provide a uniform path for the suction cups when the drive shaft 82 is rotated.
  • a cam follower not shown
  • the suction cups and drive rod are moved under a guided linear motion "M" towards and away from the carton during one complete rotation "R”of the drive shaft.
  • a vacuum break is provided in the housing 86 which is used in conjunction with a vacuum supply to set the vacuum connection and cut off points thereby determining when the carton is held by the panel separating means 76.
  • Figure 7 shows an alternative embodiment of panel separating means, comprising three suction cups 79 mounted to a drive shaft 88 by drive rods 81.
  • This embodiment is rotated in the same way as described above and is adapted for processing at higher carton throughput. It is envisaged that both embodiments illustrated in Figures 6 and 7 are compatible to be used together according to the velocity requirements of each unit and/or the carton throughput of the packaging machine.
  • only one panel engaging means can be used to separate the panels, although it is envisaged that the opposing panel(s) of the carton should be held and/or supported by suitable means known in the art.
  • rotary suction cups to separate carton panels to the conveyor
  • the present invention can be used or adapted to be used with other types of mechanism without departing from the scope of the invention.
  • a suction cup assembly could be mounted to an endless chain on a guide track, the chain being moved by a servo motor. This arrangement advantageously enables the panel separating means to adopt a different path or be in contact with the panel for a longer time period.
  • the carton 52 is brought into a set up condition: the lower belt set terminates short of panel separating means 76, 78 and the carton is moved downstream by the upper belt unit only.
  • the suction cup 79 of the far side panel separating means 78 is rotated and caused to engage the first or side panel 14 of the carton and vacuum is applied to the suction cup.
  • the far side panel separating means 78 is caused to increase its rotational velocity by the control means so that the suction cup 79 is accelerated relative to the moving carton blank.
  • the suction cup is also caused to move away from the carton by the cam effect of the opening wheel so that side panel 14 and leading end panel 18 are separated and moved apart from the handle structure 20.
  • the suction cup of the nearside panel separating means 76 is rotated and caused to engage the opposing second or side panel 12 of the carton blank.
  • Vacuum is applied to the suction cup 79 mounted on the nearside panel separating means 76 and the electronic cam effect causes the suction cup to move away from the handle structure 20 thereby separating leading side panel 12 and trailing end panel 16 from the handle structure 20.
  • the side panels 12, 14 are moved apart so that carton 52 is progressively brought into a set up condition (shown in Figure 1b).
  • the nearside panel separating means 76 is caused to reduce its rotational velocity so that the suction cup decelerates relative to the velocity of the carton blank as it moves through the set up station.
  • the preferred point of contact between the panel separating means 76, 78 and respective panels 12, 14 is in a central portion of the wall being separated.
  • the position will vary according to the type of carton and in particular the dimensional variations of the side and end walls for each carton type and for different carton sizes. It is envisaged that the acceleration and/or deceleration can be altered according to the type of carton being processed through the machine and throughput times required by including manual input capability in the control means.
  • the control means may be a dedicated processor or may be a control means for a packaging machine with which the apparatus of the invention is used.
  • the control means may preferably be a known programmable servo control system.
  • the end panels 16, 18 are maintained in a perpendicular relationship to the side panels 12, 14 by blocking lugs 92 (see Figures 4 and 5) mounted on a pair of side lug chain sets 94, 96.
  • the base panels 24, 26 are then outwardly folded into a substantially perpendicular relationship with their respective side panels 12, 14 by guides positioned either side of the carton 10, 52.
  • the endless chain sets 102, 104 are downwardly inclined and transport the erected carton to the loading station 100, where it is successively loaded with articles; the carton construction is completed and resulting package is transferred to the outfeed end 106 of the packaging machine.
  • the velocity and acceleration or deceleration of the suction cup 79 can be pre-set, thus reducing the amount of down time when interchanging carton types or styles.
  • the speed of operation of the apparatus is improved as well as its efficiency and durability.
  • An advantage of the present invention is the flexibility offered by the system.
  • the carton erecting mechanism of the invention has been illustrated with reference to a specific embodiment and that numerous modifications are possible within the scope of the invention.
  • the carton erecting mechanism is able to process cartons comprising numerous configurations of groups of articles covering a range of carton size and shape, for example, four, six, eight and twelve bottles without undue time being spent in adjusting the mechanism.
