TECHNICAL FIELD

[001] The present invention relates to in-line wrapping of a foldable blank around a load that is simultaneously received onto the loading space of the foldable blank.

BACKGROUND

[002] In the recent years, there has been a many-fold increase in the trend of grouping large number of items such as food items, including liquid foods, home essentials, stationary items, beverage containers, and the like, into secondary packages, for various purposes such as to enable bulk selling, easy transportation, handling, and the like.

[003] Particularly, there has been a considerable increase in use of folding box-based packages e.g. for holding various articles and therefore the number of boxes that are manufactured is increasing consistently. These packages are generally formed from foldable blanks which are folded using one or more folding mechanisms to obtain the secondary package having the desired shape and size.

[004] Numerous folding mechanisms have been proposed. In some instances, these foldable blanks are provided with score lines, fold-lines and /or cut-outs to form wall corner portions or joining portions to form a wall or corner.

[005] One such mechanism is disclosed within US patent number.

3,841 ,476, which discloses the use of a pre-cut blank of cardboard or like material to form a tray shape package. The blank is scored and provided with cut-outs to form wall corner portions and uniting portions at the ends of corresponding first wall forming portions and also to form strengthening tabs. The tray is erected by first erecting the strengthening tabs and by then erecting the first and second wall forming portions and finally bending the corner portions and uniting portions so that the latter can be secured to the second wall forming portions. However, the package formed using scoring/folding line techniques has certain limitations such as first, a special tool is required to create the fold lines and then another folding tool is required to form the package. Further, such mechanism allows only a single predetermined shape and size of packaging blanks to be created.

[006] On the other hand, current packaging mechanisms involves a process of picking up a group of articles from an infeed supply and then dropping into already formed packages supplied onto another conveying line. Accordingly, such a process first requires assembling or erecting the packaging blanks of predetermined sizes, then receiving the group of articles therein, and then closing the package. These predetermined packaging blanks are generally adapted to receive articles arranged in predetermined groups, configurations and/or patterns.

[007] Unfortunately, if the predetermined configuration, pattern and/or number of articles in a group needs to be changed, the packaging mechanism must be converted to cope with the changed packaging configuration. Consequently, the overall packaging process, accommodating various package configurations becomes highly inefficient in terms of cost as well as complexity of the packaging process.

[008] It would therefore be beneficial if the conversion of the packaging mechanism, to accommodate changing configurations, patterns and/or number of articles in a group, would not affect the overall packaging efficiency. To this end, the present invention beneficially allows articles to be dropped into a package while at the same time said package is being formed by means of erecting the packaging blank.

[009] None of the existing solutions in the art completely provide the flexibility of using a same packaging machine for varying configurations, shapes and numbers of articles to be packaged within a (secondary) packaging, while the packaging blanks for the packaging are formed the moment they are loaded with articles.

DETAILED DESCRIPTION

[0057] The present application discloses a packaging apparatus, for forming a package of a desired dimension around a plurality of articles or items including e.g. liquid foods, home essentials, stationary items, and the like. The packaging tool while being efficient, is able to form packages of different sizes instantly and in accordance with the incoming load being dropped on the load space thereof, without requiring any functional changes in the mechanical elements of the packaging tool. Further, the packaging tool is configured to receive articles onto the foldable blank and change its fold lay-out by automatically adapting the configurations of the apparatus in accordance with the incoming load. Alternatively the packaging tool may receive the incoming load directly onto the support frame, optionally in combination with a top applied means of article retention in a package in a downstream operation. While the secondary package in the context of the present invention may generally be a box shaped container formed of a foldable blank adapted to hold articles (e.g. such as beverage containers), it should be understood that the embodiments of the present invention may be applied in combination with various types, design and utilities of such packages, irrespective of size, shape and materials.

[0058] FIG. 1 illustrates a schematic diagram displaying basic components of the packaging apparatus of the present invention. As illustrated in FIG. 1 , the present invention provides a packaging apparatus 100 for forming a secondary package 150 of a predetermined dimension, from a foldable blank 180. The packaging apparatus 100 includes support means 120 extending between a receiving end E _R towards an output end E ₀ and adapted to receive a supply of a foldable blanks 180 from an incoming conveying line (not shown). The support means 120 includes a support frame 122 supported onto two or more parallel longitudinal rails 124 positioned generally transversal to a direction L of supply of foldable blanks 180 and adapted to support one of the foldable blank 180 thereon. The packaging apparatus 100 further includes an overhead frame 130 having a pair of downwardly protruding and movingly spaced apart transversal rails 132 configured thereon and adapted to define a loading space 188 onto the bottom panel 182 of the foldable blank 180 positioned onto the support frame 122. The packaging apparatus 100 further includes an article loading mechanism (not shown) adapted to load one or more articles 190, arranged in a predetermined configuration, onto the loading space 188. Additionally, the packaging apparatus includes an erecting mechanism 140. The erecting mechanism 140 includes a plurality of generally spaced apart vertical or near vertical acting pairs of pitch adjustable lugs 142, positioned onto one or more sides of the support frame 120, and at a height HE lower than a height of longitudinal rails H _L such that a upward movement of the one or more lugs engages, erects and clamps at least one or more wall panels 181 of the foldable blank 180 around the articles 190 already loaded thereon.

[0059] In operation, each of the foldable blanks 180 received at the receiving end ER of the support means 120 is first positioned onto the support frame 122, and defined with the loading space 188 using the pair of transversal rails 132 in accordance to the configuration/dimensions of the articles 190 to be packaged. Thereafter, the articles 190 are received onto the loading space 188 and the plurality of side panels 181 of the foldable blank 180 is erected by the erecting mechanism 140, while being conveyed towards the output end E ₀ .

[0060] In a preferred embodiment, as illustrated in Fig. 2a, an exemplary packaging apparatus 200 having an incoming conveying line 205 carrying a continuous supply of foldable blanks 280 and employed to package a supply of beverage containers 190 within the supply of foldable blanks 280 received at the incoming conveying line 205. The conveying line 205 is generally a conveying apparatus and in preferred embodiment includes two generally parallel circular tracks 205a, 205b together adapted to facilitate a movement of a supply of foldable blanks 280 from a source such as stack denesting operation [not shown] towards a support means 220 extending between a receiving end E _R towards an output end Eo.

[0061] An example of a foldable blank suitable for use with the present invention is illustrated in Fig. 2b; the foldable blank 280 including bottom panel 282 extended towards a plurality of wall panels 281 including a first side panel 283, a second side panel 284, a front-end panel 285 and a back-end panel 286.

[0062] The wall panels 281 of the foldable blank 280 are adapted to be folded around the bottom wall panel 282, to form a secondary package defining an inner surface (not shown) there within, and already filled with beverage containers 290. The foldable blank 280 further includes one or more side flaps 287 on at least one of the one or more side panels 281. In some embodiments, the one or more side flaps 287 of the foldable blank 280 further includes one or more engaging mechanisms (not shown) to close the package 250 from the sides thereof. The engaging mechanism may be selected from one or more of but not limited to notch based fixation mechanism, gluing, adhesive patches, retention tab, rivets, and any other suitable engaging mechanisms particularly which can be closed by an upward pushing force, conventionally known in the art and suitable for use in current invention, without deviating from the scope thereof.

[0063] As disclosed earlier and as illustrated in Figure 3, the packaging apparatus 200 includes the support means 220 adapted to receive the supply of the foldable blank 280 from the incoming conveying line 205. The support means 220 includes a support frame 222 supported onto two or more parallel longitudinal rails 224 including a first longitudinal rail 224a, and a second longitudinal rail 224b, each positioned generally transversal to a direction L of supply of foldable blanks 180 towards the output end Eo, and adapted to support one of the foldable blank 180 thereon.

[0064] In some embodiments and as illustrated in Figure 4a, 4b, 4c, the support frame 222 is a frame with variable width adapted to support foldable blanks 280 of varying dimensions D.

[0065] In one such embodiment, the support frame 222 includes a pair of finger sets 223, each supported onto one of the longitudinal rails 224. Each of the finger set 223 includes a plurality of generally parallel spaced apart fingers 226 having a predetermined space S between consecutive fingers 226 adapted to movingly receive at least one of the fingers 226 of the other set of fingers 223. The movement of the pair of finger sets 226 is facilitated by a movement of the longitudinal rails 224a, 224b, towards and/or away from each other. In an embodiment, such a movement of longitudinal rails 224a, 224b is achieved by a horizontal movement mechanism H. The horizontal movement mechanism H includes a closed loop conveyor 260 adapted to movingly receive the longitudinal rails 224a, 224b there upon through a plurality of support movers 262, at least one movingly engaged to each of the longitudinal rails 224a, 224b, such that each of the longitudinal rails 224 is independently movable in a horizontal direction generally parallel to the direction L of supply of foldable blanks, towards and/or away from each other. Such a longitudinal movement of the longitudinal rails 224 enables the movement of the pair of set of fingers 223 towards and away from each other thereby, to facilitate a movement of the pair of finger sets 223 between an overlapping configuration and a non-overlapping configuration as illustrated in Fig.3, 4a, 4b, 4c.

[0066] The longitudinal rails 224a, 224b, are mounted via hinge points 84 (shown in Fig. 7) off support movers 262 such that as the support movers travers about the curves of the open or closed loop conveyor, via a floating alignment bar, the support members are maintained parallel to each other.

[0067] The supporting member alignment bar is configured to slide and allow freedom of adjustment on the support frame width and while also accommodating any inaccuracies of the vertical alignment of the curves in the conveyor, while maintaining the support rails parallel (i.e. perpendicular to the alignment rail) .

[0068] In another embodiment in accordance with the present invention, the support frame may be foldable or collapsible upon moving the longitudinal rails towards each other.

[0069] As illustrated in fig. 7 and 8, such foldable or collapsible support frame 81 may comprise a foldable or collapsible deck comprising by a plurality of parallel elongated segments 91 moveable configured transversal to the direction of supply of foldable blanks. The foldable or collapsible deck, although made up of multiple segments, when orientated straight and pressed upon in the opposite direction to the freedom to fold direction, forms a flush, load bearing, support surface, void of major gaps or irregularities which may otherwise damage or spoil the materials placed thereon and enable successful support of even tall small diameter articles, such as tall beverage containers, with shallow tipping threshold. In an embodiment the segments may be supported by a chain and sprocket mechanism as shown in fig. 8. Preferably two or more roller chains 92 with corresponding chain support sprockets 93 enables flexible folding of the support frame upon moving the longitudinal rails towards each other.

[0070] In another embodiment as shown in fig.9, the foldable or collapsible support frame 81 may be further supported by one or more folding lattice support mechanisms assuring high load carrying capacity and a truly flat package support deck. [0071] In another embodiment as shown in fig.##, alternatively to the lattice linkages, the foldable or collapsible support frame 81 may be further supported by a folding origami-like, or Miura fold-based cell structure assuring high load carrying capacity and a flat package support frame.

[0072] Accordingly, the support means 220 is generally a cart kind of structure adapted to be movable onto the closed loop conveyor 260 between the receiving end ER and the output end Eo through the support movers 262 connected to the longitudinal rails 224.

[0073] The support frame 222 is generally positioned at a height H _s generally same as a conveying height H _c of the incoming conveying line 205 such that the frame 222 is adapted to receive the foldable blank 280 from the incoming conveyor without requiring any additional transferring means. However, in some embodiments, the support means 222 includes one or more locating mechanisms 245 adapted to properly position the one or more foldable blanks onto the support frame 224. In one such embodiment as show in fig.5, the locating mechanism 245 include one or more pushing lugs 246, each configured at the receiving end E _R of the support frame 224. Each of the pushing lugs is generally configured to push an incoming foldable blank 280 such that it is positioned completely onto the support frame 224. Further, the one or more locating mechanism 245, includes one or more corner lugs 247 positioned onto the corners of the support frame and adapted to support the foldable blanks 280 at the corners of the support frame 224 such that falling of the foldable blank 280 is avoided there from.

[0074] Alternatively, as shown in fig. 7, the locating means may include a pair of retractable location pins 83 integrated into the support frame to engage in corresponding apertures in the base panel of the foldable blank and thereby precisely locate the foldable blank upon deposition onto the support frame.

[0075] In an embodiment, preferably in addition to locating means, a series of suction cup pairs 82, preferably independently activated by vacuum pumps, is incorporated into the support frame at either side of the frame. Once the suction cups are activated and the foldable blank securely held onto the support frame, the location pins may be retracted. [0076] It should be understood that the use of location pins and suction cups is not limited to foldable and collapsible support frames, but may be used in any type of support frame used in the context of the present invention.

[0077] As illustrated in Figure 6, the packaging apparatus 200 further includes one or more pair of generally parallel, downwardly protruding, and movingly spaced apart spacing means 212 configured thereon to an overhead structure 210. The overhead structure 210 is a supporting structure adapted to support the transversal rails thereon and having a width W ₀ . In the illustrated embodiment, the overhead structure 210 is generally in the form a fixed frame. However, in other embodiments, the overhead structure 210 may be in the form of any suitable conventionally known support structure selected from one or more of but not limited to an overhead conveyor, a robotic arm, and the like.

[0078] The spacing means 212 is generally a means for defining the loading space 288 on to the foldable blank 280 in accordance to the configuration, arrangement and/or dimensions, of the one or more articles, to be packaged within the (secondary) package 250. In the illustrated embodiment, the spacing means 212 is generally in the form of a pair of movingly spaced apart downwardly protruding transversal rails 213, each movingly connected to the overhead frame 210 through one or more spacing movers 214. The transversal rails 213 are first moved down in contact with the foldable blank 280, and thereafter moved away from each other in accordance to the configuration / arrangement / dimensions, of the one or more articles, to be packaged within the package 250. Alternatively, the spacing means 212 may include any suitable mechanism conventionally known in the art for facilitating such an independent longitudinal movement of the one or more transversal rails 213 longitudinally across the overhead frame 210.

[0079] The packaging apparatus 200 further includes one or more article loading mechanisms (not shown) for loading one or more articles 290, arranged in a predetermined configuration, onto the loading space 288. [0080] The article loading mechanisms may be selected from any conventionally mechanism known in the art and suitable for picking and/or releasing articles such as e.g. beverage containers.

[0081] The packaging apparatus 200 further includes an erecting mechanism 240 adapted to erect the side panels 281 of foldable blanks 280 around the articles 290 already loaded onto loading space 288 of the bottom panel 282 of the foldable blank 280. In an embodiment, the erecting mechanism 240 includes a plurality of generally spaced apart vertical or near vertical, pitch adjustable, retractable, lugs 242, positioned onto one or more sides of the support frame 222, and at a height H _E lower than the height of longitudinal rails H _L such that a generally upward movement of the one or more individually activated pairs of lugs 242 engages and erects at least one or more wall panels 281 of the foldable blank 280 around the articles 290 already loaded thereon. In some embodiments, the plurality of spaced apart vertical lugs 242 are positioned onto a mounting means 244 having one or more mechanism for independently moving each of the plurality of lugs 242 upwardly and downwardly between a top position T and a bottom position B thereof. Such a movement of the lugs 242 upwardly engages the corresponding side panels 281 and erects it while moving towards its top position T. Further, the independent movement of the lugs 242 enables the need of only the selected lugs 242 to be moved up and/or down in accordance to a width W of the foldable blanks 280. Further in some embodiments, the generally vertical acting lugs 242 further includes means for permanently closing the flaps 287 of the foldable blank by either closing the engaging means, or in some embodiments, gluing the flaps by a gluing means configured thereon to the vertical lugs 242.

[0082] In some embodiments, the mounting means 244 is generally configured onto an outer portion O of each of the longitudinal 224 such that the vertical lugs always engage the corresponding side panels 281 during an upward movement thereof. Flowever, in other embodiments, the mounting means 244 may be positioned at any desired position in any possible way so as to erect at least one of the side panels 281 and/or the closing flaps 287 around the articles 290 already loaded onto the foldable blank 280. [0083] The vertical lugs 142 may be not only retractable, but also pitch adjustable such that each pair of lugs are positioned and act on one row of loaded articles from each side of that row. Pitch adjustment per longitudinal rail may be executed via rotation of one common shaft with different pitched scrolls or threaded adjustment between the vertical lugs, on each side of the support frame.

[0084] In an embodiment, the vertical lugs may have either fixed inclined actuation (up and down) or the option of being actuated vertically up and/or down, or with an up and outward sweep before moving in to fold up and then clamp vertical, the base minor panels of a foldable blank. The option to sweep out and up before clamping in may also have the feature to be withdrawn vertically down to clear the major panels as they are normally folded in later.

[0085] In some embodiments and as illustrated in Figure 7, the erecting mechanism 270 further includes or more secondary erecting means 225 erecting one or more ends selected from the front-end panel 285 and/or the back-end panel 286 of the foldable blank 280. In a preferred embodiment of the present invention, as illustrated in Fig. 2a, the secondary erecting means 225 include two parallel static guiding rails 275, each positioned at opposite sides of the support frame 120 and extending away from the receiving end ER towards the output end Eo in a generally vertically slanted configuration such that the each of the end panels 285, 286 of the foldable blank 280 gets gradually erected around the corresponding already loaded articles 290, while the support means 220 and in turn the foldable blank 280 already loaded with beverage containers 290, is being conveyed onto the closed loop conveyor 260 from the receiving end E _R towards the output end E ₀ . In an embodiment of the present invention, each of the two or more erecting rails of the erecting means 275 is movingly connected to the closed loop conveyor 260 using one or more erecting movers 264. Alternatively, the two or more erecting rails 275 of the erecting means 270 are positioned, one on each side of the closed loop conveyor 260 using any positioning mechanisms such as a manipulator, robotic arm, and the like. Yet alternatively, the positioning mechanism may include any conventionally known manual manipulation mechanism [0086] The packaging apparatus 200 further includes a first powering means (not shown) for enabling a movement of the overhead frame 210, the article loading mechanism 270, and the erecting mechanism 240 including the vertical lugs 242, and various sub-components thereof. In a preferred embodiment, the first powering means comprises one or more servo motors or linear motors adapted to power the overhead frame 210, the article loading mechanism 270, and the erecting mechanism 240 including the vertical lugs 242, at a first predetermined pitch facilitating a continuous operation of each of the component of the packaging apparatus 200 such that the incoming supply of the foldable blanks 280 is continuously formed into packages 250 of the desired dimensions.

[0087] Further in some preferred embodiments, the packaging apparatus 200 includes a second powering means (not shown) for enabling a movement of each of the support movers 262, and optionally also the spacing movers 214 and/or the erecting movers 264 along the corresponding tracks. In a preferred embodiment, the second powering means is one or more linear motors or equivalent transportation device allowing independent controlled movement of the movers. In such an embodiment, the linear motor is a generally moving magnet type of motor conventionally known in the art. Further in such embodiments, the linear motor utilizes the corresponding conveying track as a stator and each of the movers as a rotor thereof. In such an embodiment, the conveying tracks include a plurality of coils fixedly arranged in a longitudinal direction within the interior portion thereof.

[0092] FIG. 2 and 3 schematically show the arrangement of the basic components of the packaging apparatus 200 of the present invention. However, in the construction of commercial functional units, secondary components such as couplers, connectors, support structure and other functional components known to one of skill in the field of packaging apparatus and more particularly the packaging apparatus for secondary package for use with conveyor systems, may be incorporated within the packaging apparatus 200. Such commercial arrangements are included in the present invention as long as the structural components and arrangements disclosed herein are present. Accordingly, it is to be contemplated that the packaging apparatus 200 may be configured to be used for any kind of secondary packages of any possible shape as deems possible without deviating from the scope of the current invention.

[0093] Foldable blanks suitable for use within the context of the present disclosure may be formed from a (recyclable) material selected from one or more of, but not limited to, all kinds of papers, fiberboard, corrugated board, foldable blanks, hybrid material, light weight plastic materials, thermoplastics including acetal, acrylic, cellulose acetate, polyethylene, polystyrene, vinyl, and nylon, and any combinations thereof. Further, the size including the height, and width of the secondary package 250 to be formed, may be varied depending on the design constraints and requirements for its application. For example, within the instances when the secondary package 250 is adapted to house twelve containers in one layer in a 3x4 arrangement the loading space 288 is dimensioned accordingly. Further, in other instances, the loading space 288 may be sized and shaped to hold containers of a different or same quantity and/or size in single layer or more than one layers, and/or in different row/column arrangements (e.g., 1 x4, 2x2, 3x4, 4x6, 2c3c2, 2c6c2, 3c5, 3c5c2 etc.). [0094] In use, as disclosed earlier, the packaging apparatus 200 is adapted to be positioned onto an output line of a foldable blank stack denester carrying the foldable blanks 280 for forming generally carton shaped secondary packages 250. The packaging apparatus 200 receives a continuous supply of the foldable blanks 290 which are first defined with a loading space 288 and then loaded with one or more articles, and then erected around the already loaded articles 290, and then formed into the corresponding secondary packages 250 by action of the vertical lugs 242 of the erecting mechanism 240, which are configured to push the closing flaps 287 of the erected foldable blanks 290 in a predetermined manner so as to close the one or more side flaps 287 of the foldable blank 280 using the one or more engaging mechanism and thereby forming the secondary package 250 already loaded with articles 290 in a desired configuration, manner or group.

INDUSTRIAL APPLICABILITY

[0095] Particularly advantageously, the packaging apparatus 200 is adapted to receive a supply of foldable blanks 280, which are first defined with a loading space 288, loaded with one or more articles in any desired manner and then erected there around such that no redundant tasks of first forming the package and then loading it with articles 290 is required.

[0096] Further, the packaging apparatus is adaptable to different dimensions of foldable blanks and is therefore well suitable to process the packages of different sizes with ease and efficiently.

[0097] Additionally, the packaging apparatus 200 of the present invention, while being applicable onto the conveyor system, does not impact the rest of the conveying process.
