Definitions

  • This invention relates to packaging, particularly to the packaging of liquid, for example milk or orange juice, in cartons.
  • United States Patent Specification 3239995 discloses a machine for forming, filling, closing and sealing plastics-coated paperboard cartons in which flat sleeves are successively drawn from a magazine, erected into open-ended tubular form and loaded on to mandrels of a multi-station, indexing, bottom-forming, rotary turret. From the turret, the bottom-closed cartons are conveyed successively along a tubular trackway and then carried by an indexing chain conveyor to top- breaking, filling, top-heating, top-closing and top-sealing stations and then discharged from the machine. The sleeves and cartons are thus indexed through the machine.
  • United States Patent Specification 3280531 discloses a somewhat similar machine in which the opened sleeves are indexed along a stationary supporting track by a lifting comb-like structure positioned laterally of the track and having its teeth defining cells receiving the respective sleeves.
  • a mandrel is inserted into the sleeve, the top and bottom closure sub- panels are folded-in about horizontal edges of the mandrel and then the mandrel is removed.
  • a fin of the bottom closure is heated and, at a third station, the fin is pressure-sealed.
  • the projecting bottom fin enters a slot of a slidable track component which executes a short movement laterally of the stationary track to displace the fin flatly and in the meantime a press ram enters the open top of the carton and flattens the bottom closure.
  • the carton then proceeds to filling, top-folding, top-heating and top-sealing stations.
  • British Patent Specification 1541910 discloses an apparatus for breaking-in, or-out, or both, and sub-panels of a gable top closure of a carton and including two forked breaking elements arranged to embrace from above the respective top edges of the end sealing sub-panels.
  • Insertable into the top of the carton is a disc-like former of a ram, and two opposed stationary guides are located at the outside of the top of the carton.
  • the breaking elements fold the top closure end sub-panels about edges of the former and the guides; both sub-panels are folded inwards about the ram, or both are folded outwards about the respective guides, or one sub-panel is folded inwards about the ram and the other folded outwards about one of the guides.
  • the breaking elements perform somewhat reciprocatory motion, they are unsuitable for high-speed operation.
  • the guides extend over only a very small part of the height of the carton, they oppose distortion of the carton over only a very sm ⁇ 11 proportion of its height; in particular, they do not oppose distortion of the carton at its lower end during breaking and folding at that end.
  • United States Patent Specification 4,160,406 discloses a compact high speed carton opening and sealing machine and method employing a horizontal flat sleeve feeding mechanism.
  • Sleeves are fed into the opening station, positioned against a stop and vacuum opened from the trailing side panel.
  • the opened horizontal sleeve is maintained in a squared position and driven through the machine by flights mounted on parallel chain conveyors adjustably positioned adjacent the long sides of the sleeve.
  • the trailing and leading bottom end flaps are sequentially folded into place and then the bottom side flaps are partially folded into place. With the side flaps in a partially folded position, adhesive is applied to either or both the bottom end flaps and the bottom side flaps.
  • the partially folded side flaps are then maintained in position by a fixed anvil as the carton is delivered by the conveyor to a set of squaring stops.
  • a transversely moving platen then moves the carton laterally to clear the end stops while bringing the end and side flaps into sealing relationship under time and pressure conditions sufficient to effect adhesion between the side and end flaps.
  • the sealed carton is ejected from the machine by the movement of the succeeding carton into the sealing station.
  • the vacuum opening of the sleeve is performed by two vacuum cups applied to the lower side.
  • a method of conveying articles in the form of packaging containers comprising advancing said articles to a transfer location in respective pockets of a first conveyor closely receiving said articles but each open at one lateral side of the path of said articles, and operating a second conveyor transversely of the first conveyor to strip the articles from the respective pockets in the sense of said one lateral side, characterized in that the first and second conveyors continuously advance and the articles slide transversely of the second conveyor while being stripped from the pockets.
  • apparatus for conveying articles in the form of packaging containers comprising a transfer location, a first conveyor extending to said transfer location for advancing said articles along a path to said transfer location, respective pockets of said conveyor for closely receiving said articles but each open at one lateral side of said path, and a second conveyor arranged transversely of said first conveyor for stripping the articles from the respective pockets in the sense of said one lateral side, characterized in that the first and second conveyors advance continuously and the second conveyor is such that the articles being advanced thereby can slide transversely thereof.
  • the packaging machine is designed for high-speed packaging of liquid, for example milk or orange juice, in gable-topped cartons. It can attain a speed of at least 300 cartons per minute. It includes a feeder 1 for feeding flat carton sleeves 2 to a rotary sleeve-opening turret 3, which feeds the sleeves into chain pockets 4 of a continuously advancing endless conveyor chain 5 as the chain 5 passes around a rotary top pre-breaker turret 6.
  • Each sleeve 2 has been made from a blank (shown in Figure 11) consisting of paperboard coated on both faces with a suitable thermoplastics.
  • the pockets 4 are so designed that they closely receive the sleeves 2 with the sleeves in a fully opened, rectangular condition, the three upright walls of the pockets, and a fixed vertical guide wall along which the open side of each pocket 4 moves, substantially preventing movement of the sleeve relative to the pocket in any horizontal direction.
  • a rotary horizontal supporting plate 7 of the turret 6 prevents the sleeves 2 from falling out of the pockets 4.
  • the chain 5 advances the sleeves 2 along a fixed horizontal supporting plate 7' to over a bottom pre-breaker 8, by which bottom closure sub- panels of each carton are pre-broken along score lines, the walls of the pocket 4 and the vertical guide wall acting effectively as an encircling mandrel for maintaining the general rectangular shape of the remainder of the sleeve during this bottom pre-breaking.
  • the chain 5 forwards the sleeves 2 from the pre-breaker 8 to a pair of bottom closure ploughing-in and guide rails 9, which force towards each other lateral sub-panels of the bottom closure and which guide them in a partially open condition over a bottom heater 10 which blows hot air upwards into the bottom closure, so rendering tacky the internal thermoplastics coating thereof.
  • the chain 5 advances the sleeves 2 along the rails 9, which at their farther ends plough-in the lateral bottom closure sub- panels to a condition in which lateral sealing sub- panels thereof are virtually in contact with each other, whereupon the chain 5 forwards each sleeve 2 to a lead-in block 11 which is vertically slotted to receive the bottom sealing sub-panels and lead them into a pair of pre-sealing nip rollers 12.
  • the chain 5 advances the carton 2' so formed to a rotary filling and bottom-sealing turret 13, in which the bottom closure sealing sub-panels are held together for a relatively long time to give good sealing, and the liquid is filled into the carton which, since the liquid is cool, also assists sealing.
  • the chain 5 passes around this turret and forwards the filled cartons to a top tucker 14, from which the chain carries the cartons along between a pair of top closure ploughing-in and guide rails 15, above which is a top heater 16 which blows hot air downwards onto top closure sub-panels of the carton to render tacky the thermoplastics coatings thereof.
  • the chain 5 advances the cartons from the top heater 16 to a top sealer 17 consisting of a pair of horizontal endless chains 18 each provided with a series of horizontal sealing jaws 19.
  • the jaws 19 of the two chains 18 come together in pairs to grip between them gable top closure sealing sub-panels of the carton to form the gable top closure sealing fin.
  • the chain 5 advances the sealed cartons to a transfer location at which a continuously advancing conveyor 20 strips the sealed cartons from the continuously advancing chain 5.
  • the conveyor 20 consists of two endless chains 21 and 22 arranged parallely to each other and each moving along an endless path arranged in a vertical plane, the chain 21 being arranged above the chain 5 and the chain 22 being arranged below the same.
  • Each of the chains 21 and 22 includes slats 23 extending parallely to the conveyor 5, the lower run of the chain 21 and the upper run of the chain 22 moving in the same direction as each other, namely horizontally perpendicularly outwards of the return run of the chain 5.
  • the slats 23 of the lower run of the chain 21 and the slats 23 of the upper run of the chain 22 come to bear against the respective top and bottom fins of the cartons 2' arriving at the transfer station and thereby push laterally outwards the cartons in the respective chain pockets 4, although the chain 5 continues to push the cartons towards the turret 6, which it can do because the slats 23 allow sliding of the cartons transversely of the conveyor 20.
  • the conveyor 20, which is relatively short, moves at the same speed as a second transverse conveyor 24, which again consists of a pair of upper and lower endless chains 25 and 26 provided with slats 27.
  • the action of the chain 5 causes the cartons to slide from between their respective pairs of slats 23 to between their respective pairs of slats 27, by which they are displaced to a second bottom heater 28 which renders tacky the thermoplastics coating of the downwardly directed outside faces of the sub-panels of the bottom closure, and thence to a tucking-in device 29 for tucking inwards triangular end flaps of the bottom closure and retaining those flaps in a tucked-in condition whilst they seal against underneath surface portions of the bottom closure.
  • the feeder 1 includes horizontal guide rails 30 for the flat sleeves 2, a pack of flat sleeves 2 (not shown) being advanced stepwise by pressing fingers 31 mounted on respective slide blocks 32 themselves guided on respective guide rods 33.
  • the blocks 32 are advanced stepwise in synchronism by respective drive chains 34.
  • the sleeves 2 are supported by a horizontal rail 35 and are there stripped one-by-one from the end of the pack by a lug (not shown) provided on a horizontal endless conveying chain 36.
  • the lug pushes the stripped sleeve into a nip between a driven roller 37 and an idler roller 38.
  • the rollers 37 and 38 advance the sleeve into a position in which it is face-to-face with one of eight identical suction pads 39 (see Figure 5 and 6), against which the sleeve is pressed by a pressing-on roller device 40 shown in more detail in Figure 4.
  • the device 40 includes a vertical shaft 41 to the upper end of which is fixed a radial arm 42 which at its forked outer end is provided with a double roller arrangement 43 which is embraced by the forked outer end of the arm 42 and which is guided for movement in the fork by means of a horizontal stud 44 fixed thereto.
  • the roller arrangement 43 is urged outwardly by a helical compression spring 45 encircling the stud 44 and is limited as to its outward movement by nuts 46 on the stud 44.
  • the shaft 41 swings the roller arrangement 43 to a position in which it presses the sleeve 2 against the suction pad 39 and at the same time causes the sleeve 2 to depress and thus open a valve closure member 47 of a valve 48 of the pad 39.
  • the sleeve opening turret 6 comprises a fixed, vertical central axle 50 to the upper end of which is keyed a horizontal cam plate 51 formed with a continuous camming slot 52.
  • a vacuum line 53 which terminates at its upper end in a distributor valve 54, a rotary upper part 55 of which is connected via respective suction tubes 56 to the suction pads 39.
  • a co-axial tubular body 57 which is driven at a toothed ring 68 and to which the rotary part 55 is attached by a strap 58.
  • the body 57 has the suction pads 39 distributed around the wider, upper part thereof.
  • each bracket 59 Arranged on the body 57 adjacent to the respective pads 39 are eight cranked suction brackets 59 each provided with three small suction pads 60.
  • Each pad 60 is similar to each pad 39 in incorporating a valve openable by depression of its valve closure member by contact with a flat sleeve 2.
  • Each bracket 59 is swingable about a vertical axis in vertical bearings 61 mounted in respective horizontal flanges 69 of the wider upper part of the body 57.
  • each bracket 59 has fixed thereto a pinion 62 of a rack-and-pinion device 62, 63 of which the rack 63 is fixed to a slide bar 64 guided in the body 57 and mounting at its inner end a roller follower 65 which runs in the slot 52.
  • Each tube 56 has a branch duct 66 therefrom leading via a connector 67 to the upper end of the bracket 59, most of which is hollow so that suction can be applied to the pads 60.
  • the continuously rotating turret brings the sleeve 2 from a position shown at a in Figure 1, in which one of two adjacent panels of the flat sleeve are held by suction against one of the suction pads 39, through a position b in which the adjacent bracket 59 has been swung to bring its suction pads 60 against the other of those two panels and in which that other panel is held against the pads 60 by suction, through a position c in which the bracket 59 has been swung about its axis of turning, which coincides with the junction line between those two panels, partially to open the sleeve to a cross-section of diamond shape as shown, (since the axis of turning of the bracket 59 coincides with the junction line, the pads 60 of the bracket 59 move along an arcuate path corresponding to the natural path of movement of that other panel relative to that one panel), through a position d, in which the bracket 59 has continued to turn and brought the s
  • the top pre-breaker turret 6 comprises a plurality of top pre-breakers 70 equi-angularly spaced around the turret 6 and arranged to coincide in vertical alignment with the chain rockets 4 as these latter move around the turret 6.
  • the turret comprises a fixed vertical central axle 71 on which is mounted a rotary body 72 carrying the pre-breakers 70. Encircling the axle 71 is a fixed sleeve 73 formed with a continuous external peripheral camming slot 74. In the slot 74 there runs a roller follower 75 attached to the lower end of a reciprocatory vertical rod 76 which is guided in linear bearings 77 in the body 72.
  • a sleeve 78 Encircling the upper part of the rod 76 is a sleeve 78 in which the rod 76 is mounted by way of linear bearings 79.
  • a helical compression spring 80 acts between an annular washer 81 supported by an upwardly facing internal shoulder of the sleeve 78 and a flanged bush 82 encircling and retained on the upper end of the rod 76.
  • the sleeve 78 is attached to a vertical slide 83 mounted in a vertical guide 84 forming part of the body 72.
  • a radially outwardly projecting bracket 85 supporting, at respective lateral sides thereof, respective bearings 86 mounting respective cranked shafts 87 having respective pinions 88 fixed to the inner ends thereof.
  • each shaft 87 is located radially outwardly of its bearing 86 and, at its radially outer end each shaft 87 has fixed thereto a triangular flap 93 for pre-breaking top closure sub-panels of the sleeves 2.
  • an internal anvil consisting of a horizontal plate 90 with a downwardly tapering skirt 91.
  • each pre-breaker 70 moves around the axle 71 with the aligned pocket 4 containing a sleeve 2, its follower 75 lowers the rod 76 from its uppermost position shown in full lines in Figure 8 into its lowermost position 76' shown in dot-dash lines in that Figure.
  • the sleeve 78 strikes a hardened abutment 92 on the body 72. This occurs when the topmost surfaces of the internal anvil 90, 91 has reached the level of the lowermost boundaries of the sub-panels of the gable top closure.
  • the pre-breaker 8 includes a pre-breaker wheel 95 which rotates continuously in the sense of the arrow A.
  • the wheel 95 is in the form of a vertical plate formed with four trapezium-shaped lobes 96 equi-angularly spaced about the axis of the wheel.
  • the wheel 95 is fixed to a rotary driving flange 97 by means of bolts 98 (of which only one is shown) passing through holes 99 in the wheel 95, which holes are arcuate in order to allow for an accurate pre-setting of the angular position of the wheel 95 relative to the flange 97.
  • each sleeve 2 arrives above the wheel 95, one of the lobes 96 enters the open bottom of the sleeve and the leading face of that lobe 96 displaces forwards the leading sub-panels of the bottom closure of the sleeve 2 and its lagging face displaces rearwards the lagging sub- panels of that bottom closure.
  • the three walls of the relevant pocket 4 together with the fixed vertical guide wall closing the open side of the pocket 4, which wall is coextensive with the pocket walls insofar as its vertical dimension is concerned, act as an external mandrel for this bottom pre-breaking, the bottoms of the walls for this purpose being arranged at the level of the tops of obturating sub- panels of the bottom closure.
  • the bottom closure sub-panels are now immediately received between the rails 9 which are arranged at approximately the level of boundaries between sealing sub-panels, on the one hand, and the obturating sub-panels, on the other hand, of the bottom closure.
  • These rails initially converge and thus they plough-in, in other words swing towards each other, the lateral sub-panels of the bottom closure whereby the leading and lagging sub-panels thereof are swung increasingly away from one another.
  • the rails 9 approach the heater 10, they begin to run parallely to each other, so that the ploughing-in effect ceases.
  • the heater includes a heater box 100 extending along beneath the chain 5 and of a rectangular cross-section, as shown at 100', with a hot air outlet slot 101 formed centrally through the top wall thereof.
  • a pair of parallel guide rails 102 extending the length of the box 100.
  • the guide rails 9 and 102 are each of a tubular form and are cooled by passing cooling liquid through their interiors.
  • the arrangement is such that the lowermost extremities of the sleeve 2 slide along the guide rails 102 so that most of the hot air applied through the slot 101 to the bottom closure sub- panels is applied to the insides of those panels and renders tacky the thermoplastics coatings of those insides, particularly of the bottom closure sealing sub-panels, which are in fact nearest to the slot 101.
  • Hot air is supplied to the box 100 from a heater blower 103 via a supply pipe 104 and a flap valve 105.
  • the flap 106 of the valve 105 is movable by an operating ram 107 between its position shown in chain lines in Figure 10 in which the hot air flows into the box 100, and its position shown in dot-dash lines in Figure 10, in which the hot air is diverted to an exhaust pipe 108 and into which the flap 106 is moved automatically whenever the chain 5 is stopped, in order to avoid over-heating of the sleeves 2.
  • the rails 9 converge upwardly towards each other, as indicated at 9', and thereby force the bottom closure sub-panels further inwards towards each other.
  • the converging portion 109 merges into a parallel-sided portion 110, in which the sealing sub-panels are face-to-face with each other.
  • the filling and bottom-sealing turret 13 will now be described with reference to Figures 1 and 2.
  • the turret includes a plurality of reciprocatory bellows fillers 111 which rotate around the vertical axis of the turret in vertical alignment with the chain pockets 4 as these proceed around the turret.
  • the fillers 111 are supplied with cool liquid, such as milk or orange juice, from a tank 112 rotating with them.
  • Each filler 111 has thereabove a pneumatic ram 113 for operating the same.
  • Arranged vertically below the respective fillers 111 are respective bottom closure sealers 114.
  • Each sealer 114 includes a pair of clamping jaws 115 and 116 of which the jaw 115 is fixed relative to the rotary body 117 of the turret 13, and of which the jaw 116 is movable radially of the turret 113 relative to the jaw 115 by means of a roller follower 118 running in an annular camming slot 119 in a camming plate 120 fixed relative to the frame of the machine.
  • the chain 5 carries the bottom pre-sealed carbon from the rollers 12 to between a pair of jaws 115 and 116 and these jaws clamp together the sealing sub-panels of the bottom closure over a considerable part of one revolution of the turret 13, the corresponding filler 111 meanwhile filling the carton with the cool liquid from the tank 112.
  • the jaws 115 and 116 are in the relative positions shown at 115 and 116 in Figure 1, but, in the closed condition, they are in the relative positions shown at 115' and 116' in Figure 1.
  • the persistent clamping effect of the jaws and the cooling effect of the liquid give a very good sealing together of the inside thermoplastics coatings of the sealing sub-panels, so providing a good seal along the whole of the vertical fin of the bottom closure of the carton.
  • the chain 5 then carries the filled carton 2' to the top tucker 14 which includes a plate-form wheel 121 including four legs 122 terminating outwardly in a foot having a forwardly projecting toe 123 and a rearwardly projecting heel 124.
  • the speed of turning of the wheel 121 relative to the speed of advance of the chain 5 is such that each filled carton 2' catches up with a heel 124 of one leg 122 and thus the leading sub-panels of the top closure are pushed firmly in between the lateral sub-panels thereof, and then the toe 123 of the next leg 122 catches up with the carton and thus the lagging sub-panels of the carton are pushed firmly in between the lateral sub-panels thereof.
  • the provision of the tucker 14 ensures that any leading or lagging sub-panels which have moved out of their desired positions between the lateral sub-panels since pre-breaking at the turret 6 are brought back into their desired positions.
  • the top heater 16 will not be described in detail since it is similar to the bottom heater 10, including a heater box 125, a flap valve 126, a supply pipe 127, a heater blower 128, and an exhaust pipe 129.
  • Figure 11 shows a carton blank designed to produce a carton sleeve for use in the machine hereinbefore described with reference to Figures 1 to 10.
  • the blank consists of paperboard coated on both faces with a suitable thermoplastics.
  • parallel score lines 130 it is divided into five panels 131 to 135, of which the panel 135 will be heat-and pressure-sealed to the panel 131 to provide a side seam of the carton sleeve 2.
  • the panels 131 are divided to form five gable top closure obturating sub-panels 141 to 145, five gable top closure sealing sub- panels 151 to 155 outwardly thereof, five flat bottom closure obturating sub-panels 161 to 165, and five flat bottom closure sealing sub-panels 171 to 175 outwardly thereof.
  • Each of the obturating sub-panels 141, 143, 161 and 163 is divided into triangular sub-sub-panels by score lines 146 extending respectively from those two corner regions of the sub-panels nearest to the centre of its panel 131 or 135 to the middle of that side of the sub-panel furthest from the centre of its panel. From the junction of each pair of score lines 146 there extends centrally across the adjacent sealing sub-panel 151, 153, 171 or 173 another score line 147 parallel to the score lines 130 to divide that sealing sub-panel into two rectangular sub-sub-panels.
  • the sub-panel 145 is formed with an oblique score line 148 corresponding to one of the score lines 146 of the sub-panel 141.
  • the sub-panels 151 and 153 each in a condition folded upon itself about the score lines 147, together with the sub-panel 155, are sandwiched between the sub-panels 152 and 154 and form a sealing fin of the gable top closure.
  • the triangular flaps formed by the folded sub-panels 161 and 163 are turned underneath and the fin parts 171 and 173 are sealed to the fin parts 172 or 174, thereby to form the flat bottom of the carton.
  • the sub-panels 142 and 144 are formed with oblique score lines 149, to facilitate pulling out of the folded subpanels 143 and 153 to provide the spout.
