Description
1~ 894 This invention relates to a sorting or selecting device generally for trout and fish eggs, characterized by using differ-ent rebound capabilities of said eggs, such capabilities prevailing-ly depending on the vitality and hence on the quality of the egg.
The sorting or selecting device comprises means for arran-ging the eggs in a suitable aligned and spaced apart relationship on a rotary drum, wherein the eyys are sucti~`on dried and caused to advance to the ~one of the rebound wall, against which wall they are launched to fall down by gravity due to the differenti-ated rebound thereof into distinct separating picking means to bedischarged therefrom outside the sorting or selecting device.
At present, a photoelectric cell sorting or selecting ~ device is known which operates on the ground of the different ; colouring distinguishing vital eggs from those deprived of 1ife.
However, this sorting or selecting device is operatively very slow and can give only but a very low output.
It is the object of the present invention to provide an apparatus capable of a very high output, or capable of sorting or selecting in the same time unit a much larger amount of eggs. ~hus, ~0 the apparatus according to the invention exhibits àn output capa-bility of about ten times larger than that hitllerto obtained.
It is a fur-tller object of the present invention to pro-vide an apparatus for counting with a good approximation the num-ber of sorted or selected eggs.
.
q~
llZ0894 According to the present invention there is provided a sorting apparatus generally for trout and fish eggs of the type comprising an inclined wall, said wall providing a surface against which eggs are launched and caused to rebound there-from according to different trajectories depending on the resilience of the eggs and spaced collecting means, for collecting the eggs according to their reajectories; wherein said apparatus comprises a tank adapted to receive the eggs together with water, and a rotating drum associated to said tank and provided with a plurality of cups on the outer surface thereof, said cups being aligned in parallel rows extending along the drum generatrices and having a perforated bottom, each of said cups being designed to separately accommodate one egg therein so that, upon rotation of said drum, the eggs contained in the cups are removed from the water.
Upon rotation, the foraminous or perforated drum removes the eggs away from water, which eggs, after being dried by ventilation, are row by row aligned in front of the rebound wall and then pneumatically launched still row by row against said wall, allowing the occurrence of differentiated rebound determinlng the selection or sorting of the eggs. The latter will fall down in distinct picking means, from which they are carried to the outside.
In the figure of the accompanying drawings, the apparatus according to the invention has been schematically shown by mere way of unrestrictive example as embodied in a preferred embodiment thereof. Of course, any other embodiment following the same inventive concepts or embodying, even in a different combination, the features of the present invention, would be within the scope of the invention and accordingly within the covering field of the related patent.

In upward direction on the side facing a basin or tank
2, into which mixed water and eggs are introduced, as rotably dri-ven said drum 1 will crowd the well distributed eggs fiIling up the cups 3. Possible eggs that should remain stuck to the drum out-side of cups 3 would be washed away by a rainer 4 and broughtback to the mass.
On rotation, said drum 1 upward carries the eggs rest-ing thereon by entering said cups, dries said eggs by air suction through the bottom holes of the cups, and completes the transfer of the eqgs by carrying the latter to a position in front of rebound wall 5, against which such eggs are launched by blowing to rebound according to a different pattern for a selection or sorting to fall down separately and in accordance with the quality thereof into respective compartments 6 and 7. The eggs of the best quality, or the most rebounding eggs as provided with a higher elasticity, will fall down into compartment 6. Said com-partmentæ 6 and 7 are provided with conduits 8 and 9, respectively, the conduits having a slanting bottQm and with running rivulet water, separately discharging the selected or sorted eggs to the outside.
Internall~ ~f the drum and at the topmost section, a suction line 10 is prQvided, externally terminating in a suction fan or impeller ~nQt shown).
Still internally of the drum and at the section facing , :
i~ - 4 -said rebound wall 5, a blowing line 11 is prQvided, externally terminat~ng in a blowtng ~an ~r impeller (n~t shown).
Through a belt 12, said drum l is rotably driven by an electric motor located in a casing 13.
By means of suitable tubing (not shown), water is caused to supply said tank or basin 2, having positioned therein the eggs to be sorted ~r selected, rainer 4, and rivulets for carrying the selected or sorted eggs to the outside.
The inclination of rebound wall 5, as well as the posi-tion of partition 14 can be adjusted.
A bulkhead or baffle plate 15, which at the bottom is separated from the bottom, causes the eggs to become thoroughly distributed for passing therebeneath in the transfer movement from tank or basin 2 to drum 3.
Due to drying suction, water entering said drum is re-used for transferring to the outside the selected or sorted eggs outcoming from conduits 8 and 9, respectively, or is directly exhausted to the outside by a free outlet to which it is caused to flow.
Drum 1 is pivoted on sides 16 and 17 and rotates about a tube 18, which is partly an intake or suction tube and partly a blowing tube.
Since the eggs become aligned on the drum in an ac-curate and constant number or amount, orderly moving to the selection or sorting step, one needs only to count the number of rows passed to such a selection or sorting step or the number of revolutions of said drum, respectively multiplied by a proper coefficient, to know with a good approximation the number or amount of selected or sorted e~gs.
