Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing egg fluid remaining in eggshells and unbroken eggs in an automatic egg breaking machine.

As a processing machine for eggs (mainly chicken eggs) used as raw materials for processed foods, etc., it automatically cracks shelled eggs, extracts the yolk and albumen, and separates the yolk and albumen as needed and collects them separately. Egg breaking machines designed to do this are widely used.

However, the above-mentioned egg-breaking machine generally grips an egg with a shell in a horizontal position, applies an egg-breaking blade to the center of the lower part of the shell to crack the shell, and then opens the split eggshell from side to side to remove the yolk and white inside the eggshell. The material is allowed to fall naturally and is stored in a collection container. Therefore, depending on the state at the time of shell cracking, a portion of the egg white or egg yolk may remain in the eggshell and be discarded without being recovered entirely, which may reduce the yield of recovered eggs.

However, in the above-mentioned egg-breaking machine, an egg-breaking mechanism is attached to an endlessly wound egg-breaking machine conveyor at predetermined intervals, and the egg-breaking mechanism receives shelled eggs while moving by the belt movement of the egg-breaking machine conveyor. , breaking the eggs, collecting the yolk and albumen, and removing the eggshell after removing the residual egg fluid. Therefore, it is extremely difficult to automatically remove the residual egg fluid at a certain point during the above steps. This is difficult, and the actual situation is that it has not yet been possible to eliminate the egg fluid remaining in the eggshell.

On the other hand, eggs held in the egg-breaking mechanism may not be broken for some reason, but if the eggs are held in the egg-breaking mechanism unbroken, there will be surplus eggs in the area where new eggs are transferred. This causes the inconvenience that eggs fall and the transfer is disrupted in that area, causing other normal eggs to fall as well.

Therefore, it is necessary to take additional measures to remove unbroken eggs before the egg breaking mechanism completes one cycle and reaches the delivery area, which further complicates the structure of the automatic egg breaking machine.

In view of this, the present invention collects the egg liquid remaining in the broken eggshell by jetting pressurized air, and also configures the nozzle for jetting pressurized air to be movable, and controls the movement of the movable nozzle. Residual egg liquid in the eggshell of an automatic egg breaking machine that is capable of blowing away the egg liquid remaining in the eggshell and removing the unbroken egg by pushing out and removing the unbroken egg using the automatic egg breaking machine.

Note that when the movable nozzle 18 moves forward, if the egg held in the egg-breaking mechanism 11 is not cracked and is held as an egg with a shell, the movable nozzle 18 moves forward.
The tip of the shell egg E comes into contact with the side surface of the shell egg E, but at this time, the unbroken egg extrusion tongue piece 1 at the tip of the movable nozzle 18
8a gently contacts the unbroken egg without giving a shock,
Since the spring 29 is bent, the unbroken egg E will not be broken through. When the shape of the guide bar 27 enters the retreating region, it is followed by the restoring force of the spring 25 of the guide shaft 16 and retreats, returning to the original position.

When the removal device 12 reaches the removal area F, the egg-breaking mechanism 11 due to the high position of the guide rail 31
At the same time as the guide bar 27 tilts forward again, the movable nozzle 18 is pushed out again by the overhanging portion 27a of the guide bar 27.
The tip pushes out unbroken eggs from the egg breaking mechanism 11 and removes them. Note that at this time, the egg holding part 58 of the egg breaking mechanism 11 has been raised, and the egg holding state has been released.

In the illustrated embodiment, the end of the egg yolk and albumen collection area of the egg breaking machine conveyor is turned at an acute angle, and the device of the present invention is installed in this turning area. It may also be turned at an acute angle. It goes without saying that the mechanism for supplying and discharging pressurized air may be other than the illustrated example.

As explained above, the device for removing residual liquid in eggshells and unbroken eggs of the present invention includes a hollow movable nozzle whose both ends are closed and has pressurized air injection holes on both sides of the tip, and the movable nozzle which is extracted via a spring. a supporting means for stopping and slidably supporting the movable nozzle, and a driving means for advancing the movable nozzle so that the pressurized air injection hole at the tip thereof is positioned between the left and right broken eggshells held by the egg breaking mechanism; A hollow guide shaft whose position is fixed and which is arranged in the same direction as the movable nozzle and receives pressurized air from a pressurized air supply source is in communication with the movable nozzle and the guide shaft to supply pressurized air to the movable nozzle. By having a configuration having a pressure air path, it is possible to efficiently recover the egg fluid remaining in the eggshell after breaking the egg by spraying the pressurized air. Since the nozzle can be moved forward and backward, unbroken eggs can be pushed out and removed using the forward movement of this nozzle.As a result, there is no need to provide a separate unbroken egg removal device, and the structure of the automatic egg breaking machine is There are various effects such as being able to simplify the process.

In addition, if a pressure air supply means such as the illustrated embodiment is used together, even if the pressure air supply side and the pressure air reception side move in a circular motion while the other moves in an arbitrary trajectory, the necessary Pressurized air can be supplied only at certain times, and when the compressed air is connected to the receiving side, the air supply valve is opened and the compressed air is sent only when necessary, so the effective use of the compressed air can be achieved.
