Description

FIELD OF THE INVENTION

The present invention generally addresses a system for providing automated inspection, removal and tracking of eggs advancing along an egg conveying apparatus and prior to an egg breaking stage. More specifically, the present invention discloses a system for providing inspection, tracking and removal of selected eggs, the latter feature especially desirable in situations where eggs of a quality exceeding that minimally necessary for the breaker can be reclaimed from the main conveyor for use such as in higher demand or more lucrative in shell applications.

BACKGROUND OF THE INVENTION

The prior art is well documented with examples of egg transfer and processing machinery, such as which are located within industrial egg laying facilities and which are communicated by egg conveying belts extending from the various hen laying houses. Typical egg transfer systems include each of egg orienting, washing, and grading operations, as well as optional egg breaking in which the previously shelled eggs are reduced to yolk and albumen components for given applications, and as an alternative to other applications in which it is desirous to package the shell eggs.

Shortcomings associated with known egg transfer devices include the lack of an integrated processor control interfacing in cumulative fashion with each step of the egg transfer and processing operations, such as for constructing dedicated egg data profiles for a specified conveyor location. Additional shortcomings include the inability to effectively differentiate certain grades (including weight, color and the like) off shell eggs prior to entering the breakers, and in particular instances where it is desirable to remove certain types of eggs to be utilized in packaging operations and as opposed to being reduced to yolk and albumen components.

SUMMARY OF THE INVENTION

The present invention discloses an egg transfer system for providing automated inspection and tracking of advancing eggs prior to entering an egg breaker as well as subsequent tracking of broken egg contents. The transfer system includes a series of processing and inspection component interfacing with a central processor for grading and segregating the eggs into one of a number of classes including removal eggs. An egg accumulator communicates a series of conveyors extending from the various laying houses for delivery of a plurality of eggs. The accumulator may also include individual sub-pluralities of lanes dedicated to specified laying houses which may be independently processor controlled.

The accumulator in turn delivers the accumulated flow of eggs to one or more of an egg washer, a pre-breaker scanner, a crack detection unit, a weighing unit, an egg counter and a post breaker scanner. A plurality of strategically positioned removal gates are provided at intermediate locations of the egg transfer system, prior to the egg breakers, and which are intended to assist in the removal of specific types of eggs. In one variant, a first gate is provided for removing leaking or significantly defective eggs, a second gate for dirty eggs to be rerouted back to a preceding egg washer for rewashing, and a third gate for rerouting desirable shell eggs from a conveyor leading to the breaker for reclamation and use in alternate shell applications.

The central processor interfaces with the various stations in order to assemble a dedicated data packet of egg related data which is assigned to a progressing location on the egg conveyor (this typically consisting of interconnecting spool bar sections) upon which a specified egg is located. The central processor further includes the feature of assigning a data packet to a location subsequent to the breakers which holds specified shell egg contents (e.g. yolk cup and underneath positioned albumen tray). At least one, and typically two, manual removal locations are provided at both an intermediate (pre-breaker) egg detection and removal station, as well as the post-breaker removal station at which targeted air circulators are provided for assisting the individual sense of smell in detecting any rotten liquid egg contents indicative of a contaminated batch.

The present invention also discloses a processor control “smart box” subassembly which is capable of being retrofit installed with any existing egg transfer assembly including any one or more of the accumulating, washing, inspection/removal, and breaking stations. In this application, the necessary sensors and/or controller interfaces are installed upon the various transfer stations and are communicated to such as an Ethernet hub incorporating the any combination of controller panels and visual screen displays (such as further with touch screen capability). In this fashion, the retrofit version of the control subassembly again provides both the assembly of data profiles associated with each egg conveying location, as well as the ability to adjust (such as speed) the operational parameters associated with each station and such as in response to detected conditions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As previously described, the present invention discloses an egg transfer system, such as utilized in an industrial egg laying and processing facility, and which generally addresses the need for establishing automated identification and tracking of eggs, such as during handling operations preceding an egg breaking stage. As will be described in detail below, the egg transfer system incorporates processor technology which interfaces with each interconnecting station and which assists in assembling a data file associated with each identified and advancing egg position in order to both track and assemble data of individual egg properties and process parameters throughout the entire orientation, washing, inspection/removal and breaking processes. The processor control aspects further interface with a midpoint located egg inspection and removal subassembly which enables eggs to be selectively rerouted from the main transfer system out through one or more gates for varying purposes such as re-washing, removing damaging or leaking eggs or selective removal of superior quality eggs.

The feature of selective egg removal from the transfer assembly at a point preceding the egg breaker is especially desirable in situations where eggs of a quality exceeding that minimally necessary for the breaker (such as specialized colored and larger sized eggs) can be reclaimed from the system prior to being sent to the egg breakers. The rescue of such desirable eggs allowing for their more profitable use in higher market demand and/or more lucrative in shell applications and while ensuring that only eggs of requisite condition are sent to the breakers for reduction to yolk and albumen components.

The above stated, and referring to FIG. 1, an overall schematic view is generally illustrated at 10 of an egg transfer system. The system 10 is typically located within an industrial egg laying operation and incorporates a plurality of components or stations (hereinafter termed subassemblies) for washing, grading, and handling raw eggs from the varying laying houses.

As further depicted in the schematic view of FIG. 2, preceding the initial egg accumulator (or orientor) 12 are a plurality of individual belts 14, 16 and 18 which are intended to signify different laying houses (not shown) associated with the installed location of the egg transfer system. As is known, the laying houses each include a dedicated network of conveyors and feeders extending from the industrial laying pens, and in order that eggs laid by the hens are routed to the belts 14, 16 and 18 for subsequently delivery to the accumulator 12. It is also understood that the accumulator 12 for purposes of the disclosure can be substituted by any other form of inlet equipment or sourcing for direct in-feed of eggs to the overall system.

The accumulator 12 defines a first or inlet subassembly associated with the overall egg transfer system 10 and, as further depicted in schematic fashion in FIG. 2, a plurality of individually defined lanes and which, depending upon the size and orientation of the inlet feeder belts 14, 16, 18, define individual sub-pluralities 20, 22, and 24 of lane entry positions for feeding the eggs delivered from the respective laying houses. As will be subsequently described, the associated processor control aspects assign specified lane and spool positions to given eggs originating from a given laying house and throughout the egg transfer system.

The conveyors are each moved using such as an electric motor (servo) with a positioning device which defines where the eggs are as they are moved through the entire system. Beyond the arrangement depicted, it is understood that any other scalable arrangement can be employed, such as using fewer or more than the three laying houses depicted and/or either more or fewer lanes provided per laying house. It is also envisioned that the eggs provided along the in feed belts 14, 16 and 18 do not necessarily need to originate from laying houses, but could rather be provided from any number of offline suppliers (e.g. eggs not communicated from a facility located laying house but rather introduced in bulk after being transported from a remote location). Beyond that described, it is envisioned that any laying house or offline supplier can be assigned to any position or number of positions defined in the computer system.

As is further described in succeeding illustrations FIGS. 2-5, the transfer system 10 depicted in the non-limiting embodiment includes, in addition to the inlet accumulator 12, an egg washer subassembly 26, egg inspection and removal subassembly 28, and an egg breaker 30.

Interconnecting each of the accumulator 12, washer 26, inspection/removal 28 and breaker 30 subassemblies are individual sections of spool bars, as further shown at 32 (FIGS. 2-3) extending between the accumulator 12 and washer 26, at 34 (FIGS. 3-4) extending between washer 26 and inspection/removal subassembly 28 and, at 36 (FIGS. 4-5) extending between the inspection/removal subassembly 28 and breaker 30. The spool bar sections 32, 34, 36 each consist of a plurality of parallel aligned and spaced apart spool bars, specified ones of which are powered/rotated and, in combination with any adjoining and free-wheeling/rotating spool bars, operate to advance eggs between the subassemblies. The spool bars are of a given width and configuration which correspond to number and placement of lanes (such as fifteen) originating with the accumulator 12 and extending to the breaker 30.

As is further schematically referenced in FIG. 1, a processor/control sub-system 38 includes a plurality of input communication lines fed by sensors mounted at specified locations within each of the associated egg transfer subsystems, and in addition to a plurality of output lines (physical and/or wireless) connecting to servo-motors associated with each of the transfer subassemblies as well as inlet feed belts 14, 16 and 18 and interconnecting spool sections 32, 34 and 36. Illustrated in FIG. 1 are inlet lines 42 (washer drive), 44 (pusher drive), 46 (infeed drive), 48 (cup drive) and 50 (cracker drive). Corresponding outlet lines 52, 54, 56, 58 and 60 extend from servo motors (not shown) mounted to the driving components incorporated into each piece of equipment in paired fashion with each of the above referenced inlet lines 42, 44, 46, 48 and 50.

In this fashion, an aggregating series of input parameters are fed to the processor 38 and which progressively assemble the data packets of information beginning with each egg placement location established at lane entry positions 20, 22, 24 interfacing with the laying house belts 14, 16 and 18 and terminating in the yolk cup/albumen trays associated with each remaining egg passing through the breakers. The corresponding output lines communicate signals from the processor/controller 38 to the servo drives associated with the individual components in order to adjust various parameters (including but not limited to operating speed) associated with the laying house belts, transfer subassemblies, and interconnecting spool sections.

It should also be noted that, additional to the hardwiring scheme illustrated in FIG. 1, processor connections to the in-feed laying house belts 14, 16, 18, the accumulator 12, and washer 26 are understood to either be routed through additional wiring extending from the egg inspection/removal subassembly 28 and/or breaker subassembly 30 or, alternatively or additionally, additional wiring (or wireless connections) can be incorporated into the communication architecture between the controller 38 and these other components in order to selectively or simultaneously adjust the operating parameters of each.

Referring again to FIG. 2, each of the laying houses 14, 16 and 18 include mechanical guides for influencing eggs from a given house into assigned lane positions. As shown in FIG. 2, the non-limiting example shown includes the accumulator 12 exhibiting 1-3 entry lane positions (identified again at 20) for laying house 14, positions 4-10 (also lanes 22) for laying house 16 and positions 11-15 (also lanes 24) for laying house 18.

Alternate to laying houses it is also envisioned that the accumulator 12 can be communicated with multiple offline suppliers, and to which any position or number of positions can be defined by the associated computerized processor system. The central processor controller system see, again at 38 in FIG. 1 and as will be further described in reference to the succeeding illustrations FIGS. 19-51, precisely controls the flow of eggs, process parameters, and inspection properties of each egg through the entire transfer process, this being accomplished through the accretion of information assembled by the several successive inspection stations and which is compiled into a data packet associated with the specific egg at its dedicated conveyor position, again beginning at the point that the eggs are received at their respective lane entry positions from the laying houses 14, 16, 18 to the accumulator 12 and extending through their removal through each of the gates associated with the inspection/removal subassembly 28 or their eventual reduction in the breaker subassembly 30 to assigned yolk cups and albumen trays.

The purpose of the accumulator 12 is accumulate and orient the eggs into specific positions onto a conveyor that mechanically separates the eggs from each other through the entire process via the mechanical dividers or guides (at 62 in FIG. 2). Some or all of the individual spool bars incorporated into the interconnecting spool conveyor sections 32, 34 and 36 are again concurrently rotated utilizing an electric motor (servo), with the positioning technology incorporating subassembly specific located sensors and input lines extending to the processor 38 establishing a specific (and data assigned) advancing location for each egg as advanced through the transfer system, this also including that location being assigned to a yolk and albumen cup holder associated with post breaker operations.

Referring to FIG. 3, an enlarged sectional view is shown of the egg washer 26, succeeding the accumulator 12 as further depicted in the overall view of FIG. 1, and through which the pre-segregated eggs are maintained in position upon the interconnecting spool bar conveyor section 32. Reference is also made to FIG. 6 which illustrates a perspective view of a dual station washer 26 and which further shows the arrangement of overhead sprayer bars 64 (initial station) and 66 (succeeding station) in relation to a looped and underneath positioned conveyor (see individual sections 68). The washer 26 further depicts an inlet side 70 which connects to the spool bar section 32 depicted in FIG. 3. Also shown is a brush drive 72 with additional servo drives (not shown) being located at the removal subassembly 28 and such as which can be accessed by output line 52 schematically depicted in FIG. 1 in order to adjust the speed of the looped conveyor 68 within the washer in cooperation with or alternately from the inlet spool bar section 32 and outlet section 34.

During conveyance through the washer 26, the individual eggs (not shown) are tracked according to process parameters including without limitation wash/rinse temperatures, pH level, conductivity, detergent level and time in wash. As is further known, the purpose of the washer 26 is to clean the surface of the egg shell to an acceptable level for further processing. The ability to track washing parameters and egg shell inspection results can be used to optimize the parameters of the washing system to provide maximum throughput of eggs. The ability to provide processor based data tracking of the individual eggs, through the parameters identified, further can be used to determine if there are specific positions within the washer which are not performing correctly or if eggs from a given supplier may require different washing parameters, so as to again improve throughput.

Referring to FIG. 4 (in cooperation with succeeding FIGS. 7-13) an enlarged schematic view is illustrated of the egg inspection/removal subassembly 28 which is interconnected by spool bar sections 34 and 36. As will be individually described in succession, the inspection/removal subassembly 28 incorporates a series of stations including, from an inlet end, a vision inspection station 74, a crack detection, segregation and data assignment station 76, weighing station (see as depicted by underneath located digital scales at 78 in FIG. 9), and a plurality of targeted and automated egg removal gates (see at 80, 82, and 84). Additional features including manual (station located) egg removal, as well as egg candling (rotating) and counting (via location identity sensors as depicted in FIG. 13) occur upon the outlet spool conveyor section 36 extending from the inspection/removal subassembly 28 prior to delivery to the breaker subassembly 30.

FIG. 7, in combination with FIG. 4, depicts the first station vision inspection system 74. As previously described, the associated processor/controller 38 assigns advancing spool positions to each egg beginning at its receipt location from the specified laying house to a given entry lane 20, 22, 24 of the accumulator 12. By the point in time that the egg has been conveyed through the washer 26 to the inlet location of the inspection/removal subassembly 28, an interim/incomplete record of information pertaining to the washer parameters has already been assembled.

The vision system 74 exhibits a three dimensional cabinet or enclosure which is representatively depicted in FIG. 7 positioned in overhead and downwardly/angular positioned fashion. Although not shown, the vision system 74 incorporates a combination of light illumination and high resolution cameras (e.g. such as Ethernet connected digital cameras or the like) in order to inspect properties of each egg including without limitation dirt on shells, color of shells, broken or leaking eggs, mutilated shells or the absence of eggs. This information is interfaced to the central processor/controller 38, such as via a communication line or hardwire (see as depicted at 86) extending from the vision system 74.

Succeeding the vision system 74, the crack detection system 76 operates to inspect each egg for the existence of cracks and, if detected, an associated degree or severity. Without limitation, crack detection capabilities can be built into the overhead positioned vision system 74, such as which can provide a desired infrared or other wavelength illumination which, in combination with the rotating or candling of eggs upon a multiple lane defined conveyor construction (see FIG. 8), allow for quickly determining if any eggs are cracked or otherwise damaged. Data collected for each egg scan is incorporated into a file transmitted to the central processor 38 and assigned to each advancing egg location (throughout each spool section and interfacing/internal conveyor structure incorporated into each of the accumulator 12, washer 26, inspection/removal 28 and breaker 30 subassemblies). Also, and although not shown in FIG. 8, it is also envisioned that other or additional sensors could be located at locations, above, below or aside the conveying lanes illustrated in FIG. 8.

Following crack detection, obviously damaged and leaking eggs are discarded through the initial removal gate 80, with all remaining eggs being advanced to the next succeeding weighing component (see again FIG. 9) and which includes a plurality of individual digital scales 78 positioned within the subassembly 28 following the crack detection zone and prior to the second and third removal gates 82 and 84. The configuration of the digital scales are each such that they individually weigh each lane specific and advanced egg, with the data resulting from the digital weighing likewise being communicated to the processor 38 for incorporation into the aggregating data file/packet for that advancing egg location.

At this point, all shell egg quality data and parameters have been assigned and such that the processor 38 is configured to remove any number of the advancing eggs from the subassembly 28, such as to laterally extending and egress spool bar sections (not shown in FIG. 4) and based upon pre-set criteria which is compared to the individual egg data files assembled, such as by a look up table or the like built into the processor component 38. In one non-limiting variant, this can include the first gate 80 being instructed to remove eggs which are either leaking or exhibit major defects, the second gate 82 subsequently removing dirty eggs for rerouting by the egress spool section (again not shown) extending from the gate 82 to a reintroduction location prior to the washer 26. The third gate 84 is utilized to remove desirable eggs (typically larger sized and/or colored eggs) prior to be sent to the breaker subassembly 30, these eggs being more desirously used in more profitable shell packaging applications, with the remaining eggs being of a generally acceptable but non-remarkable quality suitable for delivery to the breakers and resultant reduction in to yolk and albumen components.

Once an egg is removed (either at this stage or subsequently) the pre-stored data characteristics need no longer be tracked through the system, with he associated egg record such as being stored in a database for purposes of future statistical evaluation. Along these lines, outright defective eggs are rejected (again gate 80), with other eggs being reprocessed if still dirty (gate 82) or subject to alternate processing (again gate 84) if higher quality or specific demand shell eggs possessing characteristics such as weight or color for routing to a grader for shell egg sales. Without limitation, the present invention contemplates the use of any number of removal gates, from one gate to any plurality thereof, and it is further understood that the removal parameters associated with any removal gate are also not limiting, this including the removal of quality shell eggs for alternate application, as well as the removal of poorer quality eggs (both shell or liquid) for either recycling (e.g. rewashing) or disposal.

FIGS. 10-12 illustrate a series of perspective, side and enlarged partial views of first selected removal gate 80 extending in communicating fashion with a side location of the subassembly 28 and which includes a belt conveyor 88 (connected to an exit ramp or other spool conveyor section depending upon the intended destination of the removed eggs and which could include damaged eggs such as from first gate 80 being quickly collected and disposed by an egress ramp, as opposed to additional spool sections for the second and third gates which carefully maintain and reroute the eggs to their intended destination). First and second bevel drive gears 90 and 92 are provided, with a shaft 94 extending from the second (driven) gear 92 both supporting and continuously drive the belt 88.

Additional to the constant lateral conveying direction of the belt 88 is the provision of a pair of widthwise extending, cylinder shaped and opposingly rotating brush elements, these including geared outer end plates 96 and 98 as best shown in FIG. 10 which are driven by a further pair of drive gear 99 and 101, the plates 96 and 98 in turn exhibiting inwardly extending and 360 degree extending tufts of bristles (see further at 100 and 102 respectively in FIG. 10 as well as illustrated in further detail at 102 in FIG. 12) in order to safely communicate eggs deposited, via descending passageways, from the above communicating lanes 76 for safe delivery upon the outlet conveyor belt 88.

By example, eggs of specific weight can be removed and rerouted through third gate 84 to a grader (not shown) for sale as shell egg product. Along these lines, a detected combination of characteristics can be used to remove specific eggs according to laying house, color, weight, cleanliness and absence of cracks. The provision of automatic removal gates results in a labor and material handling reductions (beyond that disclosed below in reference to the succeeding manual candling, inspection and removal stage) and, as a result, fewer employees are required to inspect the eggs visually and materially handle the eggs for reprocessing.

Following the three removal gates, and referring to FIG. 13, the remaining eggs pass underneath a plurality of lane aligned egg counting sensors 104 which determine the presence of an egg in each conveyor position following manual candling and prior to delivery to the egg breaker subassembly 30. A bundled communication line defining a wiring harness 106 extends from the individual sensors to the processor 38 and confirms 1) that eggs previously instructed to be to withdrawn through one of the gates are no longer present and 2) that eggs which are intended to proceed on to the breaker subassembly 30 are in fact present at this location.

The counting sensors 104 inspect the presence of each egg at an assigned conveyor lane (advancing) location established along the spool bars, following manual candling/removal and prior to breaking. Upon a designated egg counting sensor 104 detecting an egg missing where one is supposed to be, a determination is made that it is manually removed.

Reciprocally, the counting sensors 104 may detect an egg presence at a location where an egg is not supposed to be (such as indicative of one or more error conditions associated with functioning of the egg transfer system). In this instance, the processor system 38 will track the invalid egg through the remainder of the transfer system and, depending upon the system parameters, the machine can be stopped immediately, processed normally, or removed at a next available removal station.

Referring to FIG. 5, in combination initially with FIG. 14, the egg breaking subassembly 30 provides a plurality of individual breakers which are formed in multiple rows and columns defining a continuous belt extending in continuous looped fashion within a forward end of the breaker subassembly and such that a selected row of breakers (equivalent in number to the number of lanes associated with the spool section 36) are arranged in synchronized communication with delivery locations of the spool section 36. An egg breaking zone is representatively illustrated at 107 in FIG. 5 and each of the breakers depicted in FIG. 14 include upper egg configured pad supports 108, 110, 112 et seq., opposing lower and spaced apart pairs of egg supports 114, 116, 118 et seq., and lower knifes 120, 122, 124, et seq. which are respectively located between the lower egg supports.

Referring further to FIG. 15, and upon the eggs being delivered to a specified breaker, the breaker is advanced to a location at which the knife is pivoted upwardly between the lower egg supports and so that the shell egg can be fractured for reduction of its yolk and albumen components, these being delivered in gravity fashion at a removal gate location 125 (again FIG. 5) into aligning yolk cups 126, 128, 130 et seq. and albumen holders 132, 134, 136 et seq. positioned underneath the breakers (see further zone 138 in FIG. 5). Similar to the breakers, the yolk cups and albumen trays are likewise mounted in similar row and column arrangement such that they define a second looped belt which interfaces with the breakers (subsequent reference is made to screen illustration 260 in FIG. 28 and in which cracker/breaker belt 135 interfaces with fluid cup/tray belt 137). At this point, the central processor control 38 records which set of tooling is employed to break the shell and separate the inner egg contents.

As previously described, the eggs entering the breaker subassembly 30 are tracked through the entire breaking process from the central processor system 38, with the specific tooling used to break the eggs also assigned to the egg breaking data. The pluralities of yolk holding cups and underneath communicating albumen trays receive the yolk and albumen contents of each broken egg, with each specified pair of cup and tray identified by the processor 38 as holding the fluidic contents of a previously designated shell egg for which the processor has assembled a data record.

At this point, the egg yolk and albumen held within a given cup and tray is successively advanced through a series of stations including a post-breakage yolk manual operator and inspection station 139, a vision inspection station 140 with concurrent albumen (including also combined yolk/albumen and whole egg contaminated) tray emptying and, following this, yolk fluid emptying station 141 at which the contents are emptied for further processing and the date and time of this being recorded to the central processor 38. Upon being delivered to a processor identified cup and holder, the yolk cups and underlying albumen trays are passed underneath a vision scanner 142 (see again FIG. 16) which is likewise in communication with the central processor 38 which maintains the process parameters and characteristics of the yolk and albumen resulting from the breaker operation and as visualized across station 140.

The post breakage vision scanner 142 (as contrasted from the shell egg inspection vision system 74 in FIG. 7) determines, among other possible parameters, absence of yolk or the existence of blood or other impediments in the yolk indicative of a bad egg or batch of eggs and which may require disposal of the yolk and/or albumen prior to fluid collection, such as further by triggering the selected cups and trays to dump their contents into a waste drain (see as schematically depicted at 143 in screen shot 260 of FIG. 28 and as further identified at 145 in FIG. 18) incorporated into the breaker subassembly 30. Air displacement nozzles 144 (again FIG. 15) are also located at the initial receipt trays for quickly indicating the presence of rotten egg fluid contents to a manual inspector located at station 139 and in order to quickly dispose of any such contents prior to collection and contamination within a larger safe yolk and/or albumen reservoir.

As previously indicated, any cup/tray containers which have been manually (operator) emptied during the previous operation are identified and recorded to the central processor 38, with the egg content defect data stored to the central system 38. Following desirable albumen removal through drain 148, whole egg removal is accomplished through drain 150 as indicated by vision inspection station 142, and at which point the contents then progress through the automatic removal station 141 at which the contents of each cup and tray are selectively removed based upon the previously assembled inspection criteria (data record) corresponding to a desired application (yolk only, white only, admixture, etc.). Again, the record of each cup and try is recorded to the central processor 38 with any remaining egg contents are emptied for further processing.

Consistent with the final emptying stage 141 of all remaining yolk (and residual albumen) contents which survive both the process controlled vision scanning 142 and the preceding manual inspection/removal 139, FIG. 17 provides an internal view of an inclined albumen fluid collection ramp 146 located underneath a section of fluid release/pivoting albumen holding trays, a subsequent and likewise constructed yolk collection ramp successively receiving yolks deposited from pivoting yolk holding cups. FIG. 18 is a side view of fluid exit locations 145, 148, 150 and 151 again associated respectively with manual operator waste yolk/albumen (145), quality albumen (148), whole egg discharge via vision system (150) and quality yolk discharge 151 associated with the egg breaker subassembly 30.

Although not further shown, additional lengths of conduit are connected to communicate usable yolk (discharge 151) and albumen (discharge 148) from the end stage of the transfer assembly, such as for use in subsequent fluid packaging operations. The yolk discharge 151 is further illustrated at an underside remote end location of the breaker subassembly 30.

Given the above system description, reference is now further made to the screen shot illustrations set forth in FIGS. 19-51 and which collectively detail one non-limiting example of an operating program associated with central processor 38, such as is presented on a screen or monitor display and which can also include the provision of either touch screen or keyboard/mouse input features. The present invention contemplates both the integration of a central processor control into a dedicated design for an egg transfer system, as well as the retrofit adaptation of a processor with associated wiring and controls for use with an existing egg transfer system which may or may not include each of the features depicted in the illustrated design, such as the washer, breakers, and the like.

As further referenced in FIG. 1, the central processor 38 is depicted as a breaker system control panel generally referenced by dashed outline box and which incorporates each of Panel PC Controller and HMI 152, Slice I/O System for Local I/O 154, Safety Processor for Safety Slice I/O 156, Yolk Scanner Computer 158, Dirt Detector Computer 160 and collective Ethernet Hub 162 communication. As previously described, included within the overall control panel are the input/output connections to each of washer drive 164 (input line 42 and output line 52), pusher drive 166 (input line 44 and output line 54), infeed drive 168 (input line 46 and output line 56), cup drive 170 (input line 48 and output line 58) and cracker drive 172 (input line 50 and output line 60).

Finally, FIG. 51 illustrates a last control screen 502 used to load, save, look up documentation on, and edit all of the parameters incorporated within the control software and including parameters not available on other control screens.

It is understood that the processor based system explained with reference to illustrations FIGS. 19-51 consists of only one possible depiction of a software based flow scheme for accomplishing multi-stage egg tracking, data gathering and disposition, and that the present invention also contemplates the inclusion of other processor controlling schemes, such as intended to aggregate egg related data between individual egg subassemblies or stations beginning with an accumulator and including any (but not necessarily each and every) of a washer, inspector/removal and breaker subassembly.

The processor control scheme as further depicted herein provides a number of advantageous features for assembling detailed, comprehensive and enduring records of each egg originating from an in-source location (such as again a laying house or other bulk feed supply) following through egg gate removal or egg breaking and reduction to yolk and albumen components. The multi-interfacing capabilities of the processor functionality further provides the ability to detect any negative trending of operation of any of the machine components (most notably but not limited to gate removal eggs and egg breakers) and which can allow for replacement or reconfiguration prior to resulting in any significant egg losses.

Having described my invention, other and additional preferred embodiments will become apparent to those skilled in the art to which it pertains, and without deviating from the scope of the appended claims.
