     SUMMARY OF THE INVENTION 
     The present invention provides an apparatus for continuous high speed loading of chicks into handling trays which includes a chick conveyor adapted to transport chicks thereon continuously. This chick conveyor preferably includes an input end and an output end. The chicks are added to the conveyor at any point between the input end and the output end thereof and the chicks are adapted to exit from the chick conveyor adjacent the output end such as to be moved into handling trays positioned therebelow. 
     A divider apparatus is preferably positioned upon the chick conveyor and includes a plurality of divider walls to separate chicks being transported thereon into a plurality of rows thereof, normally three or four in number. 
     A tray conveyor is preferably positioned below the chick conveyor and is movable preferably in the same direction and is designed to transport handling trays with open tops to a location approximately below the output end of the chick conveyor to receive chicks exiting therefrom. The tray conveyor preferably defines a first tray position and a second tray position thereon. The tray conveyor means is adapted to sequentially move each handling tray forwardly one station, initially to the first tray position for initial filling thereof and thereafter to move the handling tray to the second tray position to allow continuous filling thereof up to full capacity and to finally remove the handling tray from the loading station and exiting therefrom. 
     A chick counter device such as a photoelectric cell or other similar device may be positioned adjacent the chick conveyor in order to count the number of chicks passing therealong into a given tray in either the first or second tray positions on the tray conveyor. 
     A diverter assembly is preferably positioned adjacent the output end of the chick conveyor to control the movement of chicks from the chick conveyor into the handling trays positioned on the tray conveyor therebelow at both the first and second tray positions. This diverter assembly preferably includes a plurality of diverter members preferably being three or four in number which are positioned adjacent the output end of the chick conveyor for controlling movement of chicks exiting therefrom. Each of the diverter members is positioned adjacent one of the three or four rows of chicks exiting from the chick conveyor in order to facilitate control of movement thereof into the handling trays therebelow. Each of the diverter members is selectively pivotally movable to a closed diverter position extending generally downwardly for deflecting chicks exiting the chick conveyor from the associated row of chicks into the handling tray positioned on the tray conveyor at the first tray position therebelow. 
     Similarly each of the diverter members is selectively pivotally movable to an opened diverter position extending downwardly and outwardly away from the chick conveyor for deflecting chicks exiting from the specifically associated row of chicks into a handling tray positioned on the tray conveyor at the second tray position therebelow. 
     A controller is included operatively secured to the diverter assembly for controlling pivotal movement of the diverter members between the open and closed position thereof and being operatively secured to the chick counter to determine the number of chicks having been loaded into each handling tray on the tray conveyor. This controller is preferably operatively secured with respect to the tray conveyor to cause sequential movement of each handling tray carried thereon to the first tray position, the second tray position and thereafter for exiting. The controller is responsive to sequentially move the diverter members one at a time from the open position to the closed position responsive to filling of the handling tray to increasingly larger percentages of full capacity thereof. The controller is responsive to the handling tray located in the second tray position being filled with chicks to full capacity to move all of the diverter members to the closed diverter position for the loading of chicks into the handling tray located in the first tray position. The controller is responsive to movement of all of the diverter members to the closed diverter position in order to cause the tray conveyor to allow movement of the filled handling tray from the second tray position and to move the handling tray being filled from the first tray position to the second tray position and to move an empty handling tray into the first tray position. This controller is responsive to initiate movement of a partially filled handling tray from the first tray position to the second tray position in order to initiate movement of all of the diverter members from the closed diverter position to the open diverter position. This controller is operative to move the diverter members from the closed diverter position to the open diverter position simultaneously with movement of a handling tray being filled from the first tray position to the second tray position in order to allow continuous filling thereof with chicks during movement thereof resulting from selective operation of the tray conveyor means. In this manner the diverters will &#34;follow&#34; the movement of the tray being filled from the first tray position to the second tray position and will continue filling thereof during actual movement thus resulting in &#34;continuous filling&#34; thereof. The controller is also responsive to sequentially move the diverter members from the open position to the closed position responsive to filling of the handling tray positioned at the second tray position to a given percentage of full capacity thereof. 
     In the preferred configuration of the design of the present invention the diverter assembly means will include a first diverter member positioned adjacent the output end of the chick conveyor adjacent the first row of chicks for controlling movement of chicks therein downwardly into the handling trays positioned at the first tray position and the second tray position of the tray conveyor therebelow. This first row of chicks and the first diverter member will be positioned on one lateral side of the chick conveyor preferably. 
     Similarly a second diverter member will be preferably positioned adjacent the output end of the chick conveyor adjacent the second row of chicks for controlling movement of chicks therein downwardly into the handling trays positioned at the first tray position and the second tray position of the tray conveyor therebelow. This second row of chicks and the second diverter member will be positioned on the opposite lateral side of the chick conveyor from the first row of chicks and the first diverter member in the preferred configuration. 
     A third diverter member will preferably be positioned adjacent the output end of the chick conveyor adjacent the third row of chicks for controlling movement of chicks therein downwardly into handling trays on the tray conveyor therebelow. This third row of chicks and the third diverter member will preferably be positioned laterally at some point between the first row of chicks and the second row of chicks on the chick conveyor. 
     A fourth diverter will also be positioned adjacent the output end of the chick conveyor adjacent the fourth row of chicks for controlling movement of the chicks therein downwardly into handling trays positioned at the first tray position and the second tray position on the tray conveyor. This fourth row of chicks and the fourth diverter member will preferably be positioned laterally between the first row of chicks and the second row of chicks on the chick conveyor at a position adjacent the third chick row. 
     In the preferred configuration the controller will be operative to urge movement of the first diverter member from the open diverter position to the closed diverter position responsive to the loading of chicks into the tray located at the second tray position reaching 90% of full capacity thereof. The controller is also operative to urge movement of the second diverter member from the open diverter position thereof to the closed diverter position responsive to the loading of chicks in the tray located at the second tray position reaching 95% of full capacity thereof. 
     The controller means is also preferably operative to urge movement of the third diverter member from the open diverter position to the closed diverter position responsive to the loading of chicks into the tray located at the second tray position reaching 98% of full capacity thereof. The controller means is operative finally to urge movement of the fourth diverter member from the open diverter position to the closed diverter position responsive to the loading of chicks into the tray located at the second tray position reaching 100% of full capacity thereof. Also, the controller preferably includes a pneumatic means operatively secured with respect to each of the diverter members for selectively controlling pivoting thereof between the open position and the closed position.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention provides an apparatus for continuous high speed loading of chicks 10 into a plurality of handling trays 12. The chicks 10 are carried upon a chick conveyor 14. 
     Chick conveyor 14 includes an input end 16 and an output end 18. Chicks 10 are fed onto the chick conveyor 14 at any convenient point between the input end 16 and the output end 18 thereof. The direction of movement of the chick conveyor 14 is shown by directional arrow 68 with movement of chicks 10 being generally from the input end 16 toward the output end 18. At the output end 18 the chicks are designed to exit as shown by exiting chicks 20 for movement downwardly onto handling trays positioned therebelow. 
     While traveling upon the chick conveyor 14, preferably, the chicks 10 are divided by a divider means 22 including a plurality of divider walls 24 designed to divide the chicks 10 into a plurality of rows of chicks. In the preferred embodiment the divider walls 24 will divide the chicks into four individual rows shown best on FIG. 2 as first chick row 54, second chick row 56, third chick row 58 and fourth chick row 60. The first row of chicks 54 and the second row of chicks 56 will be positioned preferably on the outermost lateral edges of the conveyor. 
     In this manner chicks 10 will be continuously supplied by the chick conveyor 14 at the output end 18 thereof in four given rows, 54, 56, 58 and 60, respectively. 
     A tray conveyor 26 will preferably be positioned below the chick conveyor 14 and will be capable of movement in the tray conveyor movement direction shown by arrow 70 which is preferably parallel to the movement direction of chick conveyor 14 and therebelow. Tray conveyor 26 will define a first tray position 28 shown in FIG. 1 to be immediately below the output end 18 of the chick conveyor 14 and a second tray position 30 positioned immediately downstream from first tray position 28 and at a location downwardly and slightly outwardly from the output end 18 of chick conveyor 14. 
     In operation the tray conveyor apparatus 26 will be periodically operable to move the trays forward one tray position. As shown in FIG. 1, the first tray position 28 is positioned immediately upstream of the second tray position 30 which itself is positioned immediately upstream from the exiting tray 32. An empty tray is partially shown to the right of first tray position 28 in FIG. 1. During movement of the trays, an empty tray will move to the left as shown in FIG. 1 to the first tray position 28. The partially filled handling tray 12, formerly in the first tray position 28, will move to the left into the second tray position 30. The filled handling tray 12, formerly in the second tray position 30, will move to the left and will become the exiting tray 32. Once all of the trays have moved downstream on the tray conveyor 26 to the new location, movement of all of the trays will cease. 
     The tray conveyor apparatus 26 can be configured in numerous different configurations with two such constructions being currently contemplated. In one design the tray conveyor 26 is continuously operable at all times with stopping members selectively movable adjacent the edge of each tray at the first tray position 28 and the second tray position 30 to retain trays in these positions as described herein. In this embodiment the tray conveyor 26 itself will continuously rotate with the stopping members or arms holding the tray stationary in their respective positions and the tray conveyor skidding along the undersurface thereof. When movement of the trays to the next position is required the stopping members will retract to allow the trays to move downstream one station and then return as the next trays approach the first and second tray stations 28 and 30. In a second design as shown in the FIGS. 1 to 3 herein, the tray conveyor apparatus 26 can simply comprise a sequentially movable conveyor being selectively movable. In both above described configuration, the composite tray conveyor apparatus is movable and causes sequential movement of all of the trays from the first tray position 28 to the second tray position 30 and on to exiting thereof. Thus, the different configurations of the tray conveyor apparatus are functionally equivalent. 
     It is primary object of this preferred embodiment to fill each tray to an accurate count of full capacity while allowing continuous filling of trays at all times. This design does not utilize any batch loading but utilizes the much more gentle and less damaging aspect of loading from a continuously moving chick supply conveyor. For this configuration the chick conveyor 14 is continuously moving whereas the tray conveyor apparatus 26 only moves the receiving trays periodically and yet continuous loading is made possible by the diverter assembly 38. 
     Diverter assembly 38 includes a plurality of individual diverter members and in this preferred embodiment includes first diverter member 40, second diverter member 42, third diverter member 44 and fourth diverter member 46. These four diverter members are each pivotally movable with respect to the diverter support bar 64. This pivotal movability allows each of the diverters 4 through 46 to be movable between a closed diverter position 50 and an open diverter position 52. In closed diverter position 50 the diverter member is oriented downwardly for guiding movement of chicks 10 into a handling tray 12 located at the first tray position 28. When in the open diverter position 52 the diverter member 48, 42, 44 or 46 is oriented extending downwardly and outwardly in a direction away from the chick conveyor 14 as shown best in FIG. 1 to facilitate guiding of movement of chicks into the handling tray 12 positioned at the second tray position 30. 
     A chick counter means 34 which preferably includes a photoelectric sensing means 36 is preferably positioned adjacent to any possible path of movement of a chick 10 on the chick conveyor 14 and is preferably positioned within each row of chicks defined thereon. This counter means is designed to provide an accurate count of the number of chicks which have been loaded within a handling tray 12 positioned at either the first tray position 28 or the second tray position 30. 
     In the preferred embodiment shown in this design a pneumatic hose means 48 will be operatively secured with respect to a pneumatic piston means 76 in order to control movement of the individual diverters 42, 44 and 46 between the open and closed diverter positions 52 and 50 respectively. Also preferably the divider member includes three divider walls 66 which are operative to divide the chicks moving upon the chick conveyor 14 into four specific rows of chicks set forth as first through fourth chick rows 54, 56, 58 and 60 respectively. Also to facilitate guiding of movement of the chicks gently each of the diverters 40, 42, 44 and 46 is preferably formed with arcuate shapes to minimize the possibility of damaging of the chicks and to aid in gentle guiding thereof into the respective trays in the first and second tray positions 28 and 30 located on the tray conveyor 26. 
     In operation the design of the present invention is that all of the chicks traveling on the chick conveyor 14 in all of the rows of chicks will be loaded into the handling tray 12 positioned at the second tray position 30 initially. That is, as the tray 30 is filled to 20, 30, 40, 50, 60, 70 and 80 percent capacity all four of the diverters 40 through 46 would be in the open diverter position 52 as shown in FIG. 1. A controller means 62 will be operatively connected with respect to the pneumatic cylinders associated with each of the four diverter members 40 through 46 and will also be operatively secured with respect to the photoelectric chick counter means 34. Controller 62 will also be operatively connected with respect to the tray conveyor apparatus 26 for controlling movement of trays thereupon. 
     In operation the controller 62 will sense when the handling tray 12 at the second tray position 30 has reached the 90% capacity fill condition. Once the 90% capacity of fill is reached, the first diverter member 40 will be pivotally moved from the open diverter position 52 to the closed diverter position 50. At this point all chicks within the first row of chicks 54 will start loading of the empty handling tray 12 currently positioned in the first tray position 28. At this point the second, third and fourth diverters 42 through 46 will continue to allow all chicks traveling in the second row 56, third row 58 and fourth row 60 to move into the handling tray 12 in the second tray position 30. Thus, filling of this tray will continue but at a slower pace than prior to movement of the first diverter member 40 from the open diverter position 52 to the closed diverter position 50. 
     The controller means 62 will continue to monitor the photoelectric chick counter 34 and once the loading of handling tray 12 in second tray position 30 reaches 95% capacity controller means 62 will cause movement of the second diverter member 42 from the open diverter position 52 to the closed diverter position 50. Thus, all chicks in the second row of chicks 56 will now be diverted to loading of the handling tray 12 in the first tray position 28. Thus, the rate of loading of chicks 10 into the handling tray 12 positioned in the second tray position 30 will be further decreased since once it is 95% full that tray will only be receiving chicks from the third and fourth rows 58 and 60 respectively. 
     The controller means 62 will further continue to monitor the loading of chicks into handling tray 12 in the second tray position 30 and once the number of chicks reaches 98% of total capacity the controller 62 will move the third diverter member 44 from the open diverter position 52 to the closed diverter position 50. At this point all chicks traveling in the first, second and third rows 54, 56 and 58, respectively, will be counted and continuously moved into the handling tray 12 positioned in the first tray position 28. Also at the same time the handling tray 12 in the second tray position 30 will be at the 98% filled capacity and will be receiving chicks only from the fourth row 60 of chicks 10. 
     Once the controller 62 senses that the count number of chicks in the handling tray 12 in the second tray position 30 has reached 100% capacity, it will initiate movement of the fourth diverter member 46 from the open diverter position 52 to the closed diverter position 50. At this point the handling tray 12 at second position 30 will be completely filled. Once all of the diverters 40 through 46 are in the closed position, the controller 62 will initiate operation of the tray conveyor apparatus 26 thereby moving all of the handling trays 12 on the tray conveyor 26 downstream one step. Thus, the filled handling tray 12 in the second tray position 30 will exit and become an exiting tray 32. The handling tray 12 in the first tray position 28 will move from the first tray position 28 to the second tray position 30 and an empty tray will be moved to the first tray position 28. 
     Simultaneously with movement or the receiving trays downstream one station, the controller 62 will initiate movement of all four diverter members 40 through 46 respectively from the closed diverter position 50 to the open diverter position 52. The timing of this movement is preferably oriented to coincide with the time of movement of handling tray 12 from the first tray position 28 to the second tray position 30. In this manner the chicks from all four rows of chicks 54 through 60 will be guided by the four diverters 40 through 46 into the tray as it moves from the first tray position 28 to the second tray position 30. In other words, the diverters 40 through 46 will actually &#34;follow&#34; the tray as it moves from first tray station 28 to second tray station 30 in order to continuously fill that tray. With the partially filled tray arriving in the second tray position 30 and the diverter members 40 through 46 all moving to the open diverter position 52, the cycle has been completed and all four diverters will remain in the open diverter position 52 until the controller receives information from the photoelectric counter 34 that this tray has reached 90% capacity at which time the first diverter 40 will move to the closed diverter position 50 and the cycle will begin again. 
     In this manner a continuous supply of chicks can be supplied on a chick supplying conveyor and be continuously loaded into handling trays which are moved periodically and advanced one step each time a tray is loaded to full capacity. Thus, the system of the present invention avoids batch loading of chicks into trays a hundred at a time which can damage chicks and also increase the amount of time needed for loading and significantly decrease the capacity of the automatic loading apparatus of the design. It should be appreciated that the percentages of capacity at which the diverters move from the closed diverter position 50 to the open diverter position 52 can be adjusted as needed depending on the rate of chick supply and other operating conditions. Also note that it is preferable that the rows of chicks which tend to have the greater supply of chicks be the chosen rows that continuously fill a box to 100% capacity in order to increase the operating capacity of the system. 
     In the present embodiment it can be seen that the center two rows tend to have more chicks located therein than the outer two rows and for this reason the center two rows are the last two moved from the open diverter position 52 to the closed diverter position 50 to increase the speed of operation and enable the last few chicks for loading to full capacity to be done as quickly as possible. 
     It should be appreciated that the design of the present invention can be performed utilizing different percentages for different sizes or capacities of operation. Also the number of diverters and chick rows can be of any number. Preferably, the number of chick supplying rows will be three or four in number. Also, the apparatus of the present invention can be positioned adjacent apparatus of similar or identical configuration thereby multiplying the capacity of the overall configuration. For example, two adjacent identical continuously loading systems have been found to be particularly effective with three chick supplying rows each. 
     It is only preferred that the individual rows be gradually shifted from movement into the almost full tray to the more empty tray as the sensed percentage full in the chick tray at the second station is sensed. Any number of actual rows of chicks and diverter members can be utilized in order to further fine tune the system based upon the capacity of the handling trays and the number of chicks being supplied. 
     While particular embodiments of this invention have been shown in the drawings and described above, it will be apparent, that many changes may be made in the form, arrangement and positioning of the various elements of the combination. In consideration thereof it should be understood that preferred embodiments of this invention disclosed herein are intended to be illustrative only and not intended to limit the scope of the invention.
