Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an egg breaking apparatus that automatically divides eggs such as chicken eggs and separates and recovers yolk egg whites.
[0002]
[Prior art]
For example, an egg breaking machine that automatically divides chicken eggs and separates and collects egg yolk whites is provided with an egg supply conveyor along a part of the egg breaking conveyor that rotates endlessly in a horizontal plane. The egg is delivered to the egg receiving saddle of the egg breaking mechanism that is radially attached to the egg breaking conveyor, and the egg is divided by the egg breaking knife of the egg breaking mechanism in the egg breaking process and the egg yolk egg white is separated from the shell in the cup. The egg yolk and the egg white are separated by this cup and collected respectively.
[0003]
Therefore, the conventional egg breaking mechanism generally has a length such that the tip of the egg breaking knife is aligned with the outer edge of the egg receiving saddle as seen in JP-A-6-70960. This is to prevent the tip of the breaking knife from colliding as a protruding obstacle during egg delivery to the egg transfer device that delivers the egg to the egg receiving saddle of the egg breaking mechanism.
[0004]
[Problems to be solved by the invention]
However, in the conventional structure, in the case of a chicken egg, there is almost no problem if it is an egg of a normal size (major axis 57 mm, minor axis 42 mm or less). In particular, in the case of an egg having a minor axis of about 60 mm, when the egg held on the egg receiving saddle is divided by a breaking knife, the tip of the knife is buried in the eggshell and flows out of the eggshell or from the eggshell. There is a problem that the yolk touches the cutting edge at the tip of the egg breaking knife and the yolk membrane is destroyed to form a turbulent egg, so that the yolk cannot be separated from the egg white purely, resulting in a decrease in commercial value.
[0005]
The present invention provides an egg breaking device that can perform egg breaking with a high yield without interfering with an egg transfer device while being able to break eggs without damaging the yolk even for large-diameter eggs. It was made as an issue to provide.
[0006]

[0017]
Next, the operation of the above embodiment will be described.
The egg E is delivered from the end of the egg supply conveyor 2 to the conveyor 3 with a rotating table that is temporarily stopped, and the conveyor 3 is rotated and delivered to a transfer conveyor 4 that rotates at a constant speed. In the egg transfer section A from the conveyor 4 to the egg breaking machine 1, the eggs are transferred onto the egg receiving saddles 10 of the egg breaking mechanisms 6, 6.
[0018]
Tip 18c of the egg breaking knife 18 by a knife actuation lever 22, 22 'is pushed up by the egg breaking mechanism 6,6 ... egg breaking knife 18 is cam rail C ₃ which is located in the egg transfer exchange section A 7 lowered to a position which does not project forward from the front end of the egg receiving saddle 10 as shown in conjunction with being placed in position that does not interfere with the conveyor 4, Tamagoosae member 15 eggs pressing portion pushed up by the cam rail C ₁ No. 13 is placed in a raised position where there is no hindrance to receiving the egg E.
[0019]
As described above, when the egg is received on the egg receiving saddle 10, the egg presser member 15 is rotated downward by the cam rail C ₁ , and the egg presser 13 moves the upper surface of the egg E on the egg receiving saddle 10 to the spring 12. It can be pressed by action.
[0020]
Next, when the egg breaking mechanism 6 moves to a predetermined position, the knife operating rods 22 and 22 ′ of the egg breaking knife 18 fall to the lower position of the cam rail C ₃ , and the blade 18 b at the tip thereof is lifted and rotated by the action of the spring 17. The egg E is divided into two pieces from the lower surface of the egg E. At this time, the tip 18c of the egg breaking knife 18 extends beyond the outer edge of the eggshell as shown in FIG. 6 even if it is an oversized egg, so it is buried so that the tip of the blade edge sticks into the eggshell. Thus, the egg yolk membrane is not destroyed, and therefore, there is no occurrence of a turbulent egg in which egg yolk and egg white are mixed. Moreover, since the knife operation rods 22 and 22 'are respectively extended at the rear ends of the pair of blade members 18a and 18a constituting the egg breaking knife 18 at the time of the above-mentioned cleavage, the right and left blade members 18a and 18a may be different. There is no good egg breaking.
[0021]

The egg yolk is collected by being discharged onto a collection basket by tilting the separating cup 19 at a predetermined position.
[0022]
【The invention's effect】
As described above, according to the present invention, even if an egg larger than the standard size is mixed, the tip of the blade portion of the egg breaking knife is located at a position protruding from the eggshell of the egg held on the egg receiving saddle. This prevents the blade tip from entering the eggshell and damaging the yolk, which prevents the egg yolk and the egg white from being mixed together and prevents the egg from becoming confused. Obtainable.
[0023]
Also, even if the tip of the egg breaking knife has a length that protrudes from the tip of the egg receiving saddle, in the section where the egg transfer device exists, it is retracted to a lower position that does not interfere with this device, The egg breaking knife does not collide with the egg transfer device side and can be operated safely.
[0024]
Furthermore, since the knife operating rod is extended at each rear end of the pair of blades constituting the egg breaking knife, there is no displacement movement of the right and left blades, and a good egg breaking action can be performed. The blade member can be reliably rotated by setting one knife operating rod to a lower surface below the other operating rod.
