Abstract

The present invention discloses a novel improvement applied to egg grader machines used in poultry farms and the like. Said continuous egg grader machine differs from other egg grader machines because it does not comprise the above-mentioned 90-degree curve existing in the egg circuit, i.e., the continuous egg grader machine of the present invention comprises a completely continuous linear circuit, wherein the great advantage of using the continuous egg grader machine disclosed herein is related to the gain obtained by the egg reduced speed when multiple rows of eggs are provided.

Claims

1. An improvement applied to a continuous egg grader machine comprising of at least an optical egg candling module (2), at least a weighing module (3), an egg conveyor system (4), at least an egg outlet (5), and an electronic central processing unit (6), wherein said conveyor system (4) is continuous and linear, and consists of a close belt (4.1) driven by gears (4.2);

said conveyor system (4) is also composed of a plurality of claws (4.3) arranged in multiple rows, wherein each of the claws (4.3) (4.3) has an individual locking system responsible for opening or locking said claws (4.3);

said conveyor system (4) also comprises multiple solenoids (4.4) that are responsible for interaction with the locking system of each claw (4.3);

the egg outlet (5) is a conveyor belt (5.1) that begins below the conveyor system (4) in transversal direction, and;

the continuous egg grader machine (1) also comprises an outlet (7) for out-of-specification eggs.

2. An improvement applied to a continuous egg grader machine according to claim 1 wherein said solenoids (4.4) are arranged diagonally and located on the egg outlets (5) to the conveyor belt (5.1).

3. An improvement applied to a continuous egg grader machine according to claim 1 wherein the conveyor belt (5.1) also contains just below the conveyor system (4) a dampening system (5.2) responsible for the dampening of eggs coming from said conveyor system (4).

4. An improvement applied to a continuous egg grader machine according to claim 1, wherein in a preferred configuration, the continuous egg grader machine (1) comprises a plurality of egg outlets (5), wherein each egg outlet is used to an egg specification, and in this situation, said conveyor system (4) comprises a set of solenoids (4.4) on each egg outlet (5).

5. An improvement applied to a continuous egg grader machine according to claim 1, wherein the continuous egg grader machine (1) also comprises tray storage units (8) for eggs storage.

6. An improvement applied to a continuous egg grader machine according to claim 1, wherein said electronic central processing unit (6) is responsible for trigging the solenoid (4.4).

7. An improvement applied to a continuous egg grader machine according to claim 1, wherein eggs are introduced into the optical egg candling module (2), where a screening of said eggs is performed, then, said eggs are weighed in the weighing module (3), the weighing data is stored in the electronic central processing unit (6) and then said eggs are sent to the conveyor system (4);

in said conveyor system (4), all eggs are collected by the claws (4.3), wherein only one egg is collected by each grab (4.3);

said claws (4.3), which are duly connected to the close belt (4.1), convey continuously eggs to their respective outlets defined by the weighing data, and when a particular egg that is still gripped by a claw (4.3) passes over its respective egg outlet (5), said electronic central processing unit (6) triggers the solenoid (4.4), and due to the mechanical action, said solenoid (4.4) opens said claw (4.3), which causes firstly the egg to be dispensed in the dampening system (5.2) and then said egg flows to the conveyor belt (5.1).
