Definitions
- the invention relates to packaging of primary articles, such as cans or bottles, in multiple packaged cartons. More particularly, but not exclusively, the invention relates to an apparatus and method of packaging articles conveyed in more than one adjacent streams simultaneously; an apparatus for and method of metering and grouping articles conveyed in two lines in more than one adjacent streams; a packaging line incorporating such a metering system and including an integrated tertiary packaging system and quaternary wrapping system.
- the present invention seeks to provide a number of advantages or improvements in the field of packaging.
- the invention provides a packaging machine comprising at least two independent paths upon which primary articles to be contained by a secondary carton are conveyed from an infeed end of the packaging machine to an integral tertiary packaging device wherein secondary cartons directly output from said two independent paths are merged and combined with a tertiary package characterised in that tertiary packages are conveyed along a transfer means out of said tertiary packaging device travelling at a speed the same as that of each of the paths upon which incoming primary articles are disposed.
- the packaging machine comprises a device for grouping articles operable to interact with articles on each path simultaneously.
- the device for grouping articles disposed between two adjacent ones of said paths, for grouping and metering primary articles conveyed on each of the two paths simultaneously.
- the packaging machine comprises a transfer conveyor for supplying a tertiary article to the tertiary packaging device for combination with the processed articles being merged, the transfer conveyor having an infeed end disposed above or below a horizontal plane containing said two paths and being inclined such that an output end of the transfer conveyor is disposed between and in substantially co-planar alignment with said two paths whereat the processed articles are merged and combined with the tertiary article.
- a finishing device is disposed upstream of said tertiary packaging device, the finishing device being structured and arranged to receive articles directly output from the tertiary packaging device, and to convey finished packages out of said finishing device along a transfer means travelling at the same speed as each of the paths upon which incoming primary articles are disposed.
- the packaging machine comprises means for supply of secondary packages to each of the two paths for combination with the primary articles; a means for supply of tertiary packages for combination with the primary articles and secondary packages, the means of supply of the tertiary package being up stream of the means for supply of the secondary article; and a single loading device operable to load, in turn, secondary packages and tertiary packages to the respective means for supplying secondary and tertiary articles.
- a second aspect of the invention provides, a device for grouping articles to be contained by a secondary carton, the device comprising a first series of spacer elements arranged to move along a pre-determined path, each spacer element operable to engage at least one article from a first infeed stream and to convey articles through a working reach of the device, the device further comprising a second series of spacer elements arranged to move along a similar pre-determined path, each spacer element of the second series operable to engage at least one article from a second infeed stream of articles, characterised in that a spacer element of the first series of spacer elements is coupled to a spacer element of the second series of spacer elements by a drive means such that the coupled spacer elements are conveyed at the same speed.
- the spacer elements of the first and second series are disposed back-to-back and operate on separate streams of primary articles disposed on separate independent conveyors to synchronise the processing of primary articles on said separate independent conveyors such that primary articles processed by the device as they are conveyed on each of said separate independent conveyors are similarly grouped and metered and output from the output end of their respective separate independent conveyor in synchrony.
- spacer elements of the first series are coupled to spacer elements of the second series in pairs by means of a common bar and said pairs of spacer elements structured and arranged to follow a cam-path of the device to control and synchronise their journey through the working reach of the device.
- the invention provides a loading device for supplying articles such as blanks to a machine for processing those articles, the loading device comprising a loading mechanism (70), a conveyor (32) for supplying pallets loaded with articles (8); a conveyor (36) for removal of empty pallets (4) and a first pallet lift (38) wherein the conveyor (32) for supplying pallets loaded with articles (8) is disposed in substantially parallel alignment with the conveyor for removal of empty pallets such that full pallets are deliverable as empty pallets are removable.
- the loading device further comprises a second conveyor for supplying loaded pallets and a second pallet lift, wherein the same loading mechanism is also operable to take articles from a loaded pallet on the second conveyor and supply them to another in-feed point of a packaging machine and wherein the second pallet lift is operable to move a pallet from the second conveyor for supplying pallets to the said conveyor for removal of empty pallets, which conveyor for removal of empty pallets services both the first and second conveyors for supplying loaded pallets.

- Fig. 7 shows an enlarged view of a tertiary packaging section of the packaging line of Figure 1.
- a packaging line of the present invention will be described with general reference to each of the Figures 2 - 7.
- the present invention provides for the efficient packaging of primary articles such as cans or bottles (C) into secondary cartons, such as the exemplary top-gripping clips 8a, 8b (as shown in Figures IA and IB) by utilising two incoming streams of articles.
- the articles on each incoming stream are processed simultaneously thus doubling the output compared to a single article stream packaging machine running at an equivalent linear speed.
- the packaging line 10 of the present invention is shown in Figure 2.
- the packaging line comprises an infeed end generally denoted by reference 56; an auto-loading assembly generally denoted by 16 for loading secondary carton blanks 8 and tertiary carton blanks 6; a tertiary carton infeed mechanism, generally denoted by reference 12; a secondary package 8 to tertiary package 6 loading section generally denoted by reference 24 and a finishing device 14.
- the packaging line 10 accommodates primary articles C conveyed in two streams on a first conveyor 26 and accommodates primary articles C conveyed in two streams on a second conveyor 28.
- the first and second conveyors, 26, 28 receive, at one end, primary articles C from the output end of a bottling or filling line and deliver the articles C, at their other end to the infeed end 56 of the packaging line 10.
- the conveyors 26, 28 may be of adjustable width to enable a variety of articles C (such as 330ml cans to 500ml bottles) to be accommodated by the packaging line.
- each of the first and second conveyors 26, 28 is sized to accommodate two primary articles C side-by-side.
- a first stream of primary articles C is denoted in Figure 3 by reference 42 and a second stream of primary articles C is denoted by 44.
- Secondary cartons 8a and 8b are structured to accommodate four and six cans C arranged in 2x2 and 2x3 configurations respectively. It will be realised upon reading the following description with reference to the drawings that the secondary packaging clips 8a and 8b are illustrative examples of secondary packages or secondary carton wrappers and it is envisaged that the packaging machine of the present embodiment and other embodiments can accommodate different types of secondary packages, (more generally indicated in Figures 2 - 8 by reference numeral 8) for containing, as well as cans, other primary articles such as bottles and for example plastic dairy pots. Such primary articles may be contained in the secondary cartons in variety of configurations. The direction of travel of the primary articles C is denoted by arrow 'X'.
- an auto-loading assembly 16 is provided.
- the auto-loading assembly 16 is most clearly shown in Figure 3.
- the auto-loading assembly 16 comprises a loading mechanism 70, a conveyor 32 for supplying pallets loaded with secondary carton blanks 8; a conveyor 34 for supplying pallets loaded with tertiary carton blanks 6; a conveyor 36 for removal of empty pallets 4; a first pallet lift 38 and a second pallet lift 40.
- the auto-loading assembly 16 is compact and therefore minimises the amount of floor space required to supply pallets loaded with secondary and tertiary carton blanks 30, 38. Additionally, by automating this process, the need for an operator is alleviated.
- the auto-loading assembly 16 operates by the conveyors 32 and 34 supplying pallets 30 loaded with secondary carton blanks 8 and pallets 46 loaded with tertiary carton blanks 6 respectively.
- a lift 40, 38 is provided at the end of each conveyor 32, 34 .
- a lift 40, 38 is not holding a pallet 30, 46
- a loaded pallet 30, 46 is supplied by the appropriate conveyor 32, 34.
- the loaded pallet 30, 46 is in this embodiment moved from the end of the supply conveyor 32, 34 onto the associated adjacent lift 40, 38 by the loading mechanism 70.
- a transfer means connected to the lift 40, 38 is used to transfer a pallet 30 loaded with secondary carton blanks 8 and pallets 46 loaded with tertiary carton blanks 6 to the associated lift 40, 38.
- the loading mechanism 70 (fitted with an articulated lifting arm 72) picks up a stack of blanks 8 or 6 using an articulating lifting arm 72 and loads the blanks 8; 6 onto the appropriate hopper 48/50 or 52 respectively.
- the lift 40, 38 holding the empty pallet 4 is lowered substantially to the same height as the conveyor for empty pallets 36.
- the empty pallet is transferred, in this embodiment by the loading mechanism onto the conveyor for empty pallets 36 which is operable to remove the empty pallet(s) away from the auto-loading assembly 16.
- the pallet conveyors 32, 34, 36 are controlled using a programmable logic controller and therefore no human operator of the machine is required in this area.
- the outward conveyor 36 for removal of empty pallets 4 is disposed below the conveyor 34 for supplying pallets 46 loaded with tertiary carton blanks 6. This means that the supply and removal mechanism are accommodated within the same floor space and thereby minimise the amount of floor space required to supply loaded pallets and remove loaded pallets. This compact solution reduces the area required by the packaging line 10.
- the outward conveyor 36 is disposed below the other conveyor 32 for supplying pallets 30 loaded with secondary cartons 8.
- both inward supply conveyors 34, 32 have their own outward conveyor 36.
- a further advantage of the present invention is gained because the tertiary carton lift 5 and tertiary carton hopper 54 are disposed within operable reach of the loading mechanism 70.
- the loading mechanism 70 can supply blanks 8 to both hoppers 48, 50 for the secondary blanks and to the tertiary carton lift 52 that in turn supplies the tertiary carton hopper 54.
- the packaging line of the present invention is structured and arranged such that the supply and infeed of the secondary carton blanks is situated in close proximity to the supply and infeed of tertiary carton blanks and therefore a single loading mechanism 70 can efficiently serve them both, thus increasing efficiency (by virtue of requiring less components and/or machine operators) and a more compact packaging line 10.
- star wheels 62 are known in the art for regulating article flow. In this embodiment four star wheels are used on for each side of each incoming stream of articles 42, 44. In other embodiments where one or each stream comprises only a single line of articles the number of star wheels may be reduced. In an alternative embodiment, where greater than two incoming streams of articles are accommodated the number of star wheels is greater than four.
- each star wheel 62 is provided with its own independent driver, preferably a servo-motor. By having independently driven star wheels, the packaging line remains fully adjustable in order to ensure synchronised incoming streams 42, 44.
- the metering mechanism 64 (described below) groups the incoming streams of articles 42, 44 into the required configuration.
- the secondary carton blanks 8 hold 6 articles C in a 2x3 configuration (see Figure IB).
- the metering mechanism 64 of the present embodiment is operable on each side of each incoming stream of articles 42, 44 and separates the articles C into groups of 2x3 articles.
- each of the first and second hoppers 48, 50 simultaneously supplies an individual blank to a rotary vacuum mechanism 58 which through the use of vacuum suction cups 60 (known in the art) deposits a blank 8 simultaneously onto a group of articles C in each incoming stream 42, 44.
- a rotary vacuum mechanism 58 is used to supply blanks 8 to each of the incoming streams 42, 44. This simplifies the processing and minimises the number of required motors.
- each incoming stream 42, 44 comprises different articles C and C (not shown).
- This optional feature whilst incorporating a slight increase in complexity provides the advantage that the packaging line 10 can offer a greater degree of flexibility.
- first and second infeed streams of articles 42, 44 each comprising articles in side by side abutting relationship is introduced into each infeed end of the grouping mechanism 64.
- the line pressure of the articles C is preferably controlled by infeed star wheels 62 as is well known.
- the article grouping mechanism 64 groups the correct number of articles C per carton as described below with the mechanism also controlling the flow of articles C, so that they can be coupled with the cartons at the same rate of carton flow downstream of the grouping mechanism 64.
- the grouping mechanism 64 comprises a grouping assembly 94 positioned on each side of the article conveyor.
- Each grouping assembly 94 is similar in construction; first the outer grouping assembly 94 will be described and then an inner grouping assembly 96 (comprising two grouping assemblies disposed in back-to-back relationship) will be described.
- the assembly 96 includes a plurality of spacer elements 88 mounted on an endless conveyor comprising a spaced pair of endless chains 84.
- each spacer element 88 includes an engagement portion comprising three partly cylindrical recesses, positioned adjacent one another. If the articles to be packaged are the same size then each recess has an identical length and is shaped substantially to conform to a peripheral wall portion of a bottle or can C (or other article) with which the recess is to engage.
- the spacer elements 88 can be grouped into pairs with leading or trailing spacer elements.
- Each spacer element 88 is connected to the endless chains 94 by suitable attachment means.
- the body portion of each element is slidably mounted on a pair of bars 98 extending between and secured to the endless chains 94 (only one visible). This arrangement permits transverse movement but prevents a rotational or longitudinal movement of the spacer elements 88 with respect to the endless chains 94.
- the endless chains 94 are mounted onto guide tracks of the assembly 94.
- the assembly 94 further comprises a cam track 92 to receive the cam followers extending from each spacer element 88.
- the endless chains 94 are driven by a motor, for example a servo motor (not shown) through a drive shaft.
- a motor for example a servo motor (not shown) through a drive shaft.
- continuous downstream motion of the endless chains 94 causes the leading spacer element 88 to be deployed into engagement with the articles C before a trailing spacer element, thus causing the mechanism to form two groupings of articles having a maximum length of three articles and a relatively short pitch therebetween.
- the mechanism has a second mode of operation.
- a secondary cam track (not shown) is in another embodiment provided such that spacer elements 88 following the secondary cam track are delayed from being deployed into contact with the articles C.
- An adjustment or selecting means is provided to select whether the leading spacer element 88 enters the secondary cam track according to the particular mode of operation.
- a blocking member is preferably provided at the exit of the secondary cam track to ensure that the trailing engagement member (not depicted) does not partially retract when passing the opening or catch in the opening.
- the inner grouping assembly 96 has been structured and arranged to optimize the space required by this section of the packaging line 10.
- the spacer elements 88 on the inner grouping assembly 88 are mounted onto each end of the double ended bars 90 that extend between and are secured to the endless chains 86.
- the inner grouping assembly 96 is formed from two of the outer grouping assemblies arranged back-to-back but with the significant difference that a spacer element is mounted onto each end of the bars 92 and only two endless chains 86 are needed to drive two opposed spacer elements 88, whereas in the outer grouping assembly 94, two endless chains (or other suitable drive means) are required for only a single headed assembly.
- the inner assembly 96 is therefore narrower than the sum of the widths of two outer assemblies 94 such that a dual ended metering system is operable between the two processing streams 26 and 28. It is envisaged that in other embodiments the spacer elements on each side of the dual-ended metering system could be differently configured, arranged and/or shaped in order to accommodate different styles of articles in each of the two lanes 42, 44.
- the grouping of articles C is, as described above, adaptable such that groups of between 1 and 6 articles can be created (for 4 - 6 articles a dual cam track arrangement is needed and two adjacent spacing elements 88 operate as a pair, this is not shown).
- the grouping of the articles C is an optional feature of the general packaging line 10 and metering may be done in other ways, however for the dual lane packaging line described, the double sided grouping mechanism 96 offers a compact solution that is adaptable to different sizes of articles and can accommodate cartons requiring a variety of configurations. Because the grouping mechanism 96 is narrower than the sum of the widths of two outer assemblies 94, the overall width of the packaging line 10 is kept sufficiently narrow that collated carton groups 82 easily can be transferred onto a tertiary blank 6 (see description below).
- the spacing elements on one side of the grouping assembly 96 might differ in shape and/or size than those of the other side to accommodate different types of article being provided on the first and second processing lines 26, 28.
- the final tertiary package would contain say two packs of cans and two packs of bottles.
- the carton package is completed by passing the grouped articles and secondary carton through finishing mechanism 68, in this case a pair of rollers 68 which apply pressure to each side of a package to ensure that the side portions of the carton have been secured in place.
- finishing mechanism 68 in this case a pair of rollers 68 which apply pressure to each side of a package to ensure that the side portions of the carton have been secured in place.
- the completed package 80 is then transferred to a delay mechanism comprising a single lug 76, lug chain.
- the travel of a leading package 82 is slowed and an immediately trailing package catches up.
- the slowing of a package to create a group of 2 packages is achievable with a system of belts, wheels, a robot or chains with and cam path such that articles are regrouped into 2x6 articles (2 packages of articles arranged in a 2x3 configuration or 3 packages arranged in a 2x2 configuration) and is not limited to the mechanism described herein.
- tertiary carton blanks 6 are transferred, along a conveyor 78 from the lift for case packer blanks 52 onto the tertiary carton hopper 54 and then conveyed underneath and between the grouping mechanisms of the first incoming stream 42 and second incoming stream 44.
- the linear dimension of the packaging line is reduced and made more compact.
- tertiary carton blanks 6 The delivery of tertiary carton blanks 6 is synchronized with the assembly of the carton packages 80 such that the tertiary carton blanks arrive proximate the level of the grouped packages 82 and between the two processing streams (see Figure 8). Almost immediately the construction and grouping of a pair of packages 80 in each processing stream is completed a tertiary blank 6 is supplied to receive them.
- a transfer robot 18 is provided either side of processing streams 42, 44 to move the collated pair of packages 82 of each processing stream 42, 44 onto the tertiary blank 6 disposed therebetween (as shown in Figure 7).
- the pitch of the packaging line 10 is maintained and the tertiary packaging assembly is formed as an integral part of the packaging line 10 without the need for conveying the finished packages 82 to a separate sub-assembly for transferring the collated secondary packages to a tertiary package.
- the tertiary packages are transferred by a rotator robot 20 and transferred to a finishing device, in this embodiment a shrink wrapping device.
- the construction of the carton 8 as illustrated in the Figures provides an illustration of how the benefits of the present invention can be applied to a specific secondary carton formation and tertiary packaging into a crate. It is envisaged that cartons formed by a different series of sequential folding operations, preferably in a straight line machine, could be assembled by a packaging machine according to the invention without necessarily involving the grouping, forming and finishing steps described. As such the invention should not be construed as being limited in application to the specific carton or article types described or folding and construction process described and these aspects may be altered according to particular manufacturing requirements.
- the present invention provides improvements in the field of packaging machinery.
- articles are collated using a secondary clip, the grouped articles are then transferred along a conveyor to a second in-line sub-assembly, a divider, where the single line is split so that two side-by-side packages can be transferred to a third in-line sub assembly.
- Tertiary package blanks are supplied to the third in-line subassembly and the secondary packages are loaded into the tertiary packs which are then conveyed along to a fourth in-line subassembly where shrink wrap finishing is conducted.
- the average length of such a machine is 300m, whereas the aforedescribed packaging line of the present invention is only 120m.
- the single line machine is known to run at an average linear operational speed of 760m per minute whereas the double line integrated packaging line of the present invention only needs to run at an average linear operational speed of 380m per minute to produce 300 cartons per minute (comprising 4 articles in a 2x2 configuration) and 50 tertiary packages (comprising 24 articles).
- the present invention provides a compact and efficient machine having a high-throughput yet being less than half the length of an equivalent known machine and able to operate at half the linear running speed of known machines without compromising the throughput.
- finishing device is omitted or in other embodiments where the finishing device is present, the finishing process may be other than shrink wrapping.
- the metering device may comprise two dual sections and two single sections.
- the in feed of the tertiary package in such an embodiment may be disposed between the first and second and/or second and third lanes or alternatively, may be aligned with the end of the second lane such that cartons from the second lane are immediately fed onto the tertiary carton blank and the secondary cartons from the first and third processing lanes are transferred by the transfer robot onto the tertiary package.
- optimum benefit in reduced complexity is gained by using two processing lines and although it is envisaged that more than two processing lines can be used, it will be understood that the advantage of reducing the linear dimension will be offset by the necessary increased width of such a packaging machine.
