Title: Intermittent case packer assembly and methods

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This is a United States national utility patent application filed pursuant to 35 USC § 111(a) claiming priority under 35 USC § 120 of/to U.S. Pat. Appl. Ser. No. 62/233,104 filed Sep. 25, 2015 and entitled INDIVIDUAL QUICK FROZEN FOOD INTERMITTENT CASE PACKER ASSEMBLY &amp; METHODS, the disclosure of which is hereby incorporated by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     The present invention is generally directed to one or more of systems, subsystems, apparatuses, assemblies, subassemblies, and/or methods for intermittent case packing. More particularly, the instant disclosure is notionally directed to the one or more of systems, subsystems, apparatuses, assemblies, and subassemblies (and/or related methods), configurable for each of flat and vertical packing operations, and contextually, and without limitation, to flexible article, e.g., bagged individual quick frozen food articles, packing. 
     BACKGROUND 
     It is well known that frozen food packaging must maintain its integrity throughout machine filling, sealing, freezing, storage, packing, transportation, thawing, and often cooking. Improvements in food handling, preparation and freezing has enabled a heretofore unseen variety of foodstuff to be widely available and desirable. 
     In the culinary arts, the term IQF stands for “individually quick frozen.” IQF foods are notable for the fact that each individual piece of food is frozen separately from all the others, thus defeating both real and perceived drawbacks and making such foodstuff easier to work with. Non-limiting examples of IQF foods are fruits (e.g., and especially, blueberries, strawberries and peaches); vegetables such as corn, peas and green beans; seafood such as shrimp and scallops; or poultry, such as individual chicken parts such as breast, tenders or wings; and, processed potatoes, commonly in the form of “fries.” 
     Whether in the context of IQF foodstuff or otherwise, flexible bags or the like are becoming/have become especially favored. Both commercial and retail offerings from a single source/provider are the norm, with a variety of package styles, configurations, and/or sizes for each category of purchaser. Needless to say, with the current state of affairs, a one-size-fits-most case packing system has gone the way of the dinosaur. There remains a need to at least maintain, if not improve upon system processing versatility characterized by minimal downtime, change parts etc. Moreover, there remains a need to reduced mechanical and/or operational complexity, minimize a footprint for such system, and provided an alternative to what are generally high cost robotic solutions. 
     SUMMARY 
     A system for loading an accumulated article group into a case is provided. The system is advantageously characterized by assemblies that are readily and quickly configurable and reconfigurable for high throughput flat and vertical packing operations. The system generally includes an article accumulation station, a grouped article loading station, and a pusher assembly. 
     The accumulation station is characterized by an article receiver assembly for selective aggregating receipt of articles in furtherance of delimiting an accumulated article group. The accumulation station is further characterized by a grouped article guide structure within which the accumulated article group is positionable by operation of the article receiver assembly. 
     The grouped article loading station is characterized by a gate assembly having first and second operable configurations. The gate assembly includes an actuatable gate, the accumulated article group passing through the actuatable gate during loading of the accumulated article group into a case presented for receipt of the accumulated article group. 
     The pusher assembly is characterized by an actuatable pusher effectuating a transfer of the accumulated article group from the accumulation station to the grouped article loading station. Flat packing operations are effectuated via transfer of the grouped article guide structure, and thus the accumulated article group therein, over the actuatable gate of the first operable configuration for the pivotable gate assembly by the pusher. Vertical packing operations are effectuated via transfer of the accumulated article group to the actuatable gate of the second operable configuration of the pivotable gate assembly. Via contemplated, minimal, change parts and operatively robust elements such as, but not limited to a grouped article guide structure of an article accumulation station, and a selective orientable gate assembly of a grouped article loading station, a relatively small footprinted system possessing supreme reliability for the either of flat or vertical pack processing of a wide dimensional range of articles characterized by flexible containers (e.g., bags), with resort to expensive robotics, is provided. More specific features and advantages obtained in view of those features will become apparent with reference to the drawing figures and DETAILED DESCRIPTION OF THE INVENTION.

     DETAILED DESCRIPTION 
     Preferred, non-limiting systems, subsystems, assemblies, subassemblies, structures and/or mechanism are generally shown and described in connection to a preferred, non-limiting intermittent case packer, advantageously, but not necessarily, an intermittent case packer, more particularly, a case packer configurably convertible for and between flat and vertical pack operations. Prior to a presentation of particulars, preliminary remarks are provided as to the depictions of the figures herein. 
     A contemplated, non-limiting convertible intermittent case packer system, configured for “flat” pack operations, is generally illustrated in  FIG. 1  wherein the system is advantageously but not necessarily characterized by processing areas I-VII generally corresponding to: (I) article conditioning (i.e., pre-conditioning, e.g., settling of article (e.g., package/bag) contents and air evacuation of same to substantially conform the package/bag to the contents); (II) article infeeding; (III) article accumulation/grouping; (IV) case erection and presentation; (V) case blank pick-up via a blank gantry assembly; (VI) a case blank magazine; and, (VII) a packed case outflow. The system of  FIG. 1 , area I elements omitted and parts removed to reveal process flow clarity, is next shown, two views ( FIGS. 2 &amp; 3 ), with processing areas II &amp; IV subsequently emphasized ( FIG. 4 ). Thereafter, an operational processing sequence for the  FIG. 2  subsystem is illustrated ( FIGS. 5-10 ), with a functional operation sequence associated with subassemblies of processing areas III &amp; IV, operatively configured for article group flat packaging operations ( FIGS. 11-14 ) and article group vertical packing operations ( FIGS. 16 &amp; 17 ) thereafter provided, a subassembly conversion depiction (i.e. in furtherance of changing between flat and vertical article group packing operations) is likewise provided ( FIG. 15 ). Finally, hidden elements of the  FIG. 16  vertical pack subassembly are readily appreciated in the depictions of  FIGS. 18 &amp; 19 . 
     With initial general reference to the depictions of  FIGS. 1-4 , and reference thereafter to the sequence of  FIGS. 5-10 , discussion will proceed with regard to article accumulation/grouping, grouped article transfer, and grouped article case loading. More particularly, such discussion proceeds in connection to processing areas III &amp; IV, with reference to horizontal/flat pack operations as depicted. 
     General processing is best appreciated with initial reference to system  10  of  FIG. 1 , and select reference to any of  FIGS. 2-4 . Commencing in processing area I, the advantageous preconditioning of articles (e.g., bags of individual quick frozen (IQF) foodstuffs such as, but hardly limited to french fries) is conducted via first  12  and second  14  preconditioning conveyors. Notionally, preconditioning aims to uniformly distribute the foodstuff in relation to its container, e.g., a bag, and to, as the case may be, evacuate the container headspace such that a flexible container closely conforms to the foodstuff. In short, preconditioning of the articles is intended to aid casing operations, and the structural integrity of a case packed with such preconditioned articles. 
     Post preconditioning, articles pass to a product placement conveyor  20  (see e.g., US 2013/0008762 (Gust et al.) which, owing to transverse oscillation ( FIG. 2 ), establishes article rows for conveyance upon article infeed conveyor  30 . Article grouping operations commence at the downstream-most portion of the article infeed conveyor, namely, at an article accumulation station  40 . As further depicted  FIG. 2 , downstream processing areas area generally and fairly characterized by a grouped article loading station  100 , a case erection and presentation assembly  130 , a case blank gantry assembly  140 , a case blank magazine  150 , and a packed or loaded case outflow assembly  160 . 
     With particular reference to  FIGS. 2-4 , and as is best appreciated with reference to  FIG. 3 , wherein processing areas III and IV are indicated in the depicted side elevation, process flow right to left, area III article accumulation/grouping is fairly characterized by a select vertical, falling transfer of articles from the infeed conveyor. More particularly, article infeed transpositing conveyor  30  conveys gapped and divided articles toward a free end portion  32  thereof adapted for translation or oscillation in the direction of article flow. Notionally, formed article rows longitudinally extend and travel toward the free end portion of the transpositing conveyor such that the downstream-most article “spills” thereover as the fully downstream extended free end portion of the transpositing conveyor is swiftly retracted in an upstream direction. 
     With specific reference to  FIGS. 3 &amp; 4 , there is depicted an article accumulation station  40  fairly characterized and/or delimited by a chute  41 . Chute  41  (i.e., a working envelope or volume if you will for the station) vertically extends downstream of transpositing conveyor  30  and upstream of operations associated with processing area IV (i.e., grouped article case loading/packing delimited by a gate assembly  102  (i.e., a chamber loader) of grouped article loading station  100 ). 
     Devices and/or subassemblies associated with article accumulation station  40 , e.g., chute  41 , advantageously include first  42  and second  44  actuatable layering shelves, an article receiver assembly  50 , and a grouped article guide structure  60  through which a portion of the article receiver is passable in furtherance of positioning an accumulated article group within same. A pusher assembly  120  acts upon the grouped article guide structure, in the as depicted flat pack subassembly configuration, so as to registeringly position the grouped article guide structure over the gate assembly in advance of loadingly transferring guidingly grouped articles to a case below the loader. 
     With primary reference now to  FIGS. 5-10 , there is illustrated an operational sequence which exemplifies article grouping, article group transfer and transferred article group case packing. Notionally, case blanks  170  are at least partially erected during article accumulation operations, with substantially formed cases  171  transferred into a loading station or area delimited by the gate assembly  102  (i.e., the case is positioned there below) in advance of transfer of the grouped article guide structure  60  into the loading station delimited by the gate assembly (i.e., the grouped article guide structure is positioned there above) by an actuatable pusher  122  of pusher assembly  120 . It is to be noted that while the subject depictions are characterized by a single shelf (i.e., shelf  42 ), general operation/function is nonetheless fairly illustrated. 
     The operational status of  FIG. 5  is one of completion/initiation. Gate  104  of gate assembly  102  is shown in an open configuration having permitted passage of an article group to the case which is shown initially exiting case presentation area IV. The gate remains open in furtherance of pivotingly accepting a substantially erect case having origins in the blank secured by overhead gantry assembly  140  as will later be appreciated in connection to subsequent disclosure. The article accumulation station is in a ready/initially active state, with an article having passed from transpositing conveyor  30  to shelf  42  via chute  41 . Grouped article guide structure  60  is positioned in/at a home position, an article group platform or support  52  (not visible, but see  FIGS. 6 &amp; 7 ) of article receiver assembly  50  shown having been upwardly advanced from a home position, to and through grouped article guide structure  60 . 
     With reference now to  FIGS. 6-10 , shelved articles pass to the article group platform  52  of article receiver assembly  50  ( FIGS. 6 &amp; 7 ). During accumulation thereon (e.g., stacking, layering, etc.), article group platform  52  is incrementally lowered, making “room” for a further/new article to the top of the pile (see/compare each of  FIGS. 6-8 ). During accumulation of the articles, case blank  170  is partially erected ( FIG. 7 ) and thereafter, substantially erected case  171  is pivotingly passed through gate  104  of gate assembly  102  ( FIG. 8 ) with article group platform  52  continuing its descent into grouped article guide structure  60 . Having been lowered to a preselect elevation sometime after the view of  FIG. 8  but before the view of  FIG. 9 , the article group supported upon platform  52  of article receiver assembly  50  is circumscribed by elements of article group guide structure  60  ( FIG. 9 ), with gate  104  of gate assembly  102  having been actuated to prohibit access to an underlying case. Next ( FIG. 9 ), actuatable pusher  122  of pusher assembly  120  is activated so as to locate article group guide structure  60 , and thus the article group essentially surrounded thereby, over top gate assembly  102 , with gate  104  thereof further actuated to permit passage of the article group from guide structure  60  to the case, pusher  122  and gate  104  thereafter reverting to permit further cycling, with the loaded case ready for transfer from case presentation area IV ( FIG. 10 ) for later processing. 
     With general reference now to  FIG. 11-19 , advantageous subassemblies of processing areas III &amp; IV are generally illustrated ( FIGS. 11-17 ), with select particulars therefore likewise depicted ( FIGS. 18 &amp; 19 ) to aid and support understanding of structures of the subassembly and/or attendant functions thereof. As previously noted, in as much as functional flow is depicted for the subassembly in relation to flat pack operations ( FIGS. 11-14 ) and vertical pack operations ( FIGS. 16 &amp; 17 ), with conversion of the  FIG. 11  subassembly from flat to vertical pack operations depicted ( FIG. 15 ), discussion next proceeds in connection to the structures of each of the subassemblies depicted. 
     With continued general reference to  FIGS. 11-19  and particular reference to the subassembly configurations of  FIGS. 11 &amp; 16 , there is illustrated article accumulation station  40  characterized by article receiver assembly  50  and grouped article guide structure  60 , grouped article loading station  100  characterized by gate assembly  102 , and pusher assembly  120  characterized by actuatable pusher  122 . Notionally, the article accumulation station is intermediate the pusher assembly and the grouped article loading station as shown. Moreover, as will be later presented, a cross dimension (z-direction) for the station is selectable, via manipulation of an adjustable framework for same, so as to conform the station to the accumulating article or article pack pattern in the cross machine direction, with an x-dimension for the accumulated article group likewise being selectable, via actuation (i.e., adjustment or resetting of a start position) of the pusher of the pusher assembly. 
     As a preliminary matter, and with reference to  FIG. 11 , notionally, a two part framework  43  (e.g., “front” and “rear” frame or framework portions  43   a ,  43   b  as shown) operatively support article receiver assembly  50  and grouped article guide structure  60 , indirectly via a guide structure carriage assembly as will be later described. Frame portions  45 ,  47  are adapted so as to draw one portion to/from the other, or to/from each other. Moreover, as will be readily appreciated subsequently, portions of the grouped article structure are operably supported so as to move with the framing in furtherance of guiding a range of variably dimensioned (z-dimension) accumulated article groups. 
     Articles exit the article infeed conveyor and “enter” the columnar article accumulation station (e.g., article chute thereof) whereupon the articles are selectively handled during a guided descent in advance of positioning the accumulated article group within the grouped article structure. As should be appreciated, it is desirable/advantageous to selectively conform at least the z-dimension of the chute to the z-dimension of the article or article group or article pack pattern, as via the aforementioned framework, with selective conforming of the x-dimension of the grouped article structure accomplished via adjustment of the pusher of the pusher assembly. 
     In addition to article receiver assembly  50  and grouped article structure  60 , article accumulation station  60  is further and advantageously characterized by a shelf or shelving, e.g., upper and lower shelves  42 ,  44  as shown. The shelves, which take the form of actuatable doors or gates which traverse the chute in section and open in the z-direction, function to buffer article flow within the chute (i.e., the shelves intermediately collect or capture articles introduced from the article infeed conveyor). As shown, shelves  42 ,  44  advantageously but not necessarily include first and second shelf portions, each shelf portion adapted to be translating or otherwise separable to permit passage (vertical) of the one of more articles received thereon to a lower shelf or a portion of the article receiver assembly. Opposingly paired sidewalls or panels  46  extend between shelves  42 ,  44  in furtherance of providing a guided egress from the upper to the lower shelf. 
     Article receiver assembly  50  generally includes an article receiver, e.g., a platform  52  as shown (see especially  FIG. 15 ), a support structure in the form of an arm  54 , and a vertical track subassembly  56  characterized by a track  57 , a carriage  58  and carriage driver, e.g., a servo  59  as shown. The article receiver platform, consistent with robust and versatile article handling aims, is advantageously a change-part, platforms dimensionally selected to generally conform/correspond with the sectional dimension of the article chute of the article accumulation station. Functionally, the article receiver ascends/descends to and through the grouped article guide structure in furtherance of receiving articles or article sub groups discharging from the shelf/shelving overlying the guide structure and positioning an accumulated article group within the guide structure. 
     The grouped article guide structure functions to align or orient, and/or maintain the alignment or orientation of articles of the accumulated article group positioned with respect thereto by the platform of the article receiver assembly. Guide structure  60  is operatively supported by assembly framework  43  via carriage assembly  70 . As best appreciated with reference to the sequence of  FIGS. 11-13 , carriage assembly  70  is advantageously, but not exclusively, characterized by a primary carriage  72  supporting a secondary carriage  74 , primary carriage  72  operably united with assembly framework  43 , secondary carriage  74  operably uniting guide structure  60  to primary carriage  72 . 
     As is readily appreciated with continued reference to  FIGS. 11-17 , carriages  72 ,  74  are generally characterized by conventional elements, such as, but not limited to, track segments  76 , track blocks  78  and a drive assembly  80  to impart the sought after motion. Notionally, guide structure  60 , or elements thereof, are operably linked or united with carriage assembly  70  for select reversible translation so as to position or locate an accumulated article group positioned within the guide structure for flat packing at the grouped article loading station (compare  FIGS. 11-14  with  FIG. 16-19 , wherein the carriage is active as to the former, via an operable link to/with the pusher of the pusher assembly, and inactive as to the latter). 
     Grouped article guide structure  60  is generally and minimally characterized by wall forming major guide panels  62  ( FIGS. 11-17 ). Major guide panels  62  extend, as shown, in the z-direction or dimension, intending to longitudinally bound the accumulated article group positionable therebetween, and further generally extend, in the y-direction or dimension, between a portion of the secondary carriage and the lowermost shelf. Major guide panels  62  are supported by carriage assembly  70 , more particularly and advantageously, but not necessarily, indirectly supported by secondary carriage  74  via a hinge assembly  64 . Via such arrangement, major guide panels  62  are readily pivotable upon release of a latch  63  or the like to access the space delimited or bounded by the major guide panels in furtherance of inspection and/or maintenance tasks, e.g., and without limitation, to facilitate change part operations in connection flat to vertical pack operation conversion as will be subsequently described ( FIGS. 16-19 ). 
     Grouped article guide structure  60  is further characterized by a minor guide panel or minor guide panels  66  as processing necessitates, minor guide panels  66  operably combinable or coupleable to other structures of article receiver assembly  50  and/or grouped article guide structure  60 . By way of illustration, there is shown a “distal” minor panel (e.g.,  FIGS. 11-14 ), advantageously but not necessarily, a panel having first and second portions  66   a ,  66   b  (see especially  FIG. 15 ), and a “proximal” minor panel ( FIG. 18 ), the relative notions of proximal and distal cited with reference to/in relation to pusher  122  of pusher assembly  120  ( FIG. 19 ). 
     Each of minor panels  66  are, as previously noted, operably coupleable/combinable and, selectively, readily and easily disintegrable from elements of grouped article guide structure  60  (i.e., in relation to the distal minor panel, see  FIG. 15 ; in relation to the proximal minor panel, see  FIG. 18 ) in furtherance of select flat or vertical pack operations, with the proximal minor panel contemplated/provided as a change part ( FIG. 18 ) in furtherance of both previously described z-dimension frame adjustability and conversion between flat and vertical pack operations. More particularly, the distal minor panel is decoupleable from/in relation to the major guide panels, and removable part-and-parcel of operational conversion ( FIG. 15 ); the proximal minor panel is likewise decoupleable from/in relation to the major guide panels part-and-parcel of operational conversion ( FIG. 17 ), and removable as a change part ( FIG. 18 , e.g.,  66 ′ for flat pack operations, combinable with major panels in furtherance of formation of/delimiting a grouped article guide “sleeve” characterized by fixedly linked major and minor panels, or  66 ″ for vertical pack operations wherein the proximal minor wall is actuatable to pass between the major guide panels in furtherance of passing an accumulated article group through the actuatable gate. 
     With particular reference now to  FIGS. 11 &amp; 13-17  of  FIGS. 11-19 , gate assembly  102  is generally and fairly characterized by actuatable gate or keeper  104 , a gate actuation subassembly  106 , case loading assists  108 , and a framework  110  to which/within which the instant components are operably united/supported. A transfer deck  112  ( FIGS. 11 &amp; 15 ) is utilized to conveyingly link the adjacent stations (i.e. article accumulation station  40  to/with grouped article loading station  100 ). As is best appreciated with reference to  FIGS. 3 &amp; 15 , and in keeping with the disclosure to this point, gate assembly  102  is hingedly or pivotably supported in relation to the subsystem/subassembly to as to be pivotingly actuated about point P in conversion from its  FIG. 11-14  orientation to its  FIG. 16-18  orientation. 
     Gate  104  advantageously, but not necessarily includes first and second gate portions  104   a ,  104   b . Each gate portion  104   a ,  104   b  is carriage or otherwise mounted within/with respect to gate assembly framework  110  for opposing reversible translation, relative to each other, in the z-dimension (see/compare, e.g.,  FIGS. 13 &amp; 14  relative to flat pack operations and  FIGS. 16 &amp; 17  relative to vertical pack operations) to permit passage of an accumulated article group therethrough. 
     With particular reference now to  FIG. 19  of  FIGS. 11-19 , pusher assembly  120  is generally and fairly characterized by actuatable pusher  122 , a pusher actuation subassembly  124 , and frame or framework  126  to which/within which the instant components are operably united/supported. Pusher  122  is carriage or otherwise mounted within/with respect to pusher assembly framework  126  for opposing reversible translation in the x-dimension, home/load pusher comparative arrangements depicted in relation to  FIGS. 11 &amp; 13  on one hand, and  FIGS. 16 &amp; 17  on the other hand. 
     As is best appreciated with reference to  FIGS. 18 &amp; 19 , a free end  123  of pusher  122  is adapted for receipt of proximal minor guide panel  66 , which as previously noted, is advantageously present in the subassembly as a change part. Notionally, the pusher acts upon the accumulated article group, advantageously, indirectly, in furtherance of transferring the accumulated article group from the article accumulation station to the grouped article loading station. 
     Proximal minor guide panel  66  is supported by (i.e., affixable to) free end portion  123  of pusher  122 . During flat pack operations, the proximal minor guide panel (e.g., minor guide panel  66 ′,  FIG. 18 ) is part and parcel of sleeve like guide structure  60  (see e.g., either of  FIGS. 5-10 , or  FIGS. 11-14 ), actuation of the pusher resulting in translation of sleeve like guide structure  60 , via its carriage mount (i.e., union of major guide panels  62  with carriage  70 ), so as to effectively transfer the accumulated article group surrounded thereby over gate  104  of gate assembly  102  for subsequent release into an awaiting case therebelow. During vertical pack operations, the proximal, and only minor guide panel (e.g., minor guide panel  66 ″,  FIG. 18 ) is not united with either of major guide panels  62 , the proximal guide panel being reversibly passed through the resulting stationary, opposingly paired major guide panels such that the accumulated article group is transferred to grouped article loading station  110 , through gate  104  of gate assembly  102  and into an awaiting case. 
     While advantageous, non-limiting systems, subsystems, apparatuses, assemblies, subassemblies, and/or methods for intermittent case packing are depicted, described and/or readily ascertained with reference to the instant disclosure, alternate not insubstantial functional equivalents are likewise contemplated to effectuate a sought after and described robust functionality. Presently known and future developed means for effectuating the noted functionalities are understood to be within the scope of the instant disclosure. 
     Thus, since the structures of the assemblies/mechanisms disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described and depicted herein/with are to be considered in all respects illustrative and not restrictive. Accordingly, the scope of the subject invention is as defined in the language of the appended claims, and includes not insubstantial equivalents thereto.
