Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for removing egg fluid remaining in eggshells in an egg breaking machine.

As a processing machine for eggs used as raw materials for processed foods, etc.
2. Description of the Related Art Egg breaking machines are widely used, which automatically crack shell eggs to extract the yolk and albumen, and if necessary, separate the yolk and albumen and collect them separately.

However, the self-cracking machine generally grips an egg in the shell horizontally, applies an egg-breaking blade to the center of the lower part to crack the shell, and then opens the divided eggshell from side to side to remove the yolk inside the eggshell. Since the egg white is allowed to fall naturally and stored in the collection container, depending on the condition at the time of cracking, the albumen may stay inside the eggshell and be discarded without being collected in its entirety. The consistency of egg whites may decrease.

In view of this, the present invention has been developed by inserting a movable nozzle with an air injection hole at the tip into the cracked shell of the split eggshell, which is being held in a gripped state, after the shell is split and the yolk and albumen are collected by gravity. , a method for removing egg fluid remaining in an eggshell in which the albumen or egg yolk remaining in the eggshell is forcibly removed by blowing pressurized air from the air injection hole at the tip of the nozzle toward the top of the inner surface of the eggshell, and this method can be directly performed. The purpose of this invention is to provide a device for removing egg fluid remaining in eggshells, which can be used for carrying out the experiment.

``Between the end of the supply conveyor 72 that transfers washed and shelled eggs E in double rows and the chain 10 that constitutes the egg-breaking machine conveyor, there is a conveyor 72 that runs at the same speed and in the same direction as the chain 10''. A delivery conveyor 73 is provided, and after the shelled eggs E are once transferred from the end of the supply conveyor 72 to the delivery conveyor 73, they are transferred to the egg breaking mechanisms 11, 11, . . . of the egg breaking machine conveyor.
It is designed to be delivered to ... in a stationary state with no relative speed difference.

The supply conveyor 72 is formed by a row of rollers 4 each having a small diameter in the shape of a cluster and a portion on which shell eggs E are placed, as shown in FIG. 1 at one end. It is designed to hold six shell eggs E.

The delivery conveyor 73 is a subrocket provided at a position away from the delivery area A. A chain wound between 5 and 75? 6, and as shown in FIG. 5 in an enlarged cross-section, rollers 78 having a longitudinal cross section of a chain 78 are connected to each other through a bracket 77, as shown in a partially enlarged cross section in FIG. The chain 76 is rotatably supported with an axis in the running direction of the chain 76 at regular intervals.

A drive roller 79 rotated through a drive system (not shown) is in sliding contact with this roller 781, so that the roller 781 is given seven rotations in the direction of the arrow in FIG. The shaft 80' of the roller 78 is pivoted at the base of both side frame portions of a support arm 81 having a U-shaped planar shape. A clutch-shaped roller 82 is rotatably supported by a shaft 83, and a shell egg E is stably held in a horizontal position above both rollers 78 and 82.

It is preferable that these rollers 78 and 82 be made of a relatively cheap material such as plastic so as not to damage the shelled egg E, and have a hollow structure to cushion the impact. One of the sprockets 75, 75 is driven by a drive source (not shown) so that the upper running side of the chain 76 is moved in the same direction and at the same speed as the moving direction of the chain 10 constituting the egg breaking machine conveyor. It is meant to be empowering. A tentacle 81a projects from the free end of the support arm 81, and this tentacle 81a slides under its own weight onto a cam rail 85 fixed to one side of a guide member 84 of the chain 76. The cam rail 85 lowers the free end of the support arm 81 at a portion facing the end of the supply conveyor 72, and raises the free end from near the middle position of the transfer area A. Near this raised position, the cam rail 85 is placed on the upper surface. It has a cam and side cam structure. Above the delivery conveyor 73 is a delivery conveyor from the L supply conveyor 72? A rotating body 86 is provided on the rollers 78 and 82 of No. 3 for intermittent supply and transfer assistance when transferring shell eggs E. This rotating body 86 has a plurality of (four in the figure) arms 889, 88... projecting in radial directions around the ball 87, as shown in part in FIG. At the tips of 88, 88..., there is a support arm 8 that supports the lower part of the shelled egg E and guides it onto the delivery conveyor 73.
9, the shelled eggs E falling from the end of the supply conveyor 72 by rotation of the shaft 87 in the direction of the arrow are delivered to the conveyor 73.
Laura? 89 - 82 It is designed to transfer the transfer to the upper part. Next, the operation of the above embodiment will be explained.

The washed shell eggs E are sent on the supply conveyor 72,
When the shell egg OE reaches its end, it is released by reversing the supply conveyor 72, but one of the support arms 89 of the rotating body 86 supports the lower surface of the shell egg OE by rotating the shaft 87 in the direction of the arrow, and gradually moves downward. The shell egg 6 is guided onto the rollers 78, 82 of the transfer conveyor 73.

of the delivery conveyor 73.

When the roller 82 is in the receiving position, the free end of the support arm 81 that supports it is lowered by the lower part of the cam rail 85 and placed below the other roller 78, and the shell egg E
The shell egg E is gradually displaced to a horizontal position by the belt movement of the delivery conveyor 73, and the shell egg E is corrected to a horizontal position by the rotation of the roller 78. As the chain 756 moves, the free end of the support arm 81 is gradually raised by the cam rail 85, and the roller 82 moves above 78, and the chain 1 of the egg sheller 1 moves at the same speed. The eggs are received and passed onto the egg receiving section 42 of the supported egg breaking mechanism 11 under a constant speed transfer state. The shelled egg E delivered to the egg-breaking mechanism 11 in this manner is moved as the chain 10 moves, and the rear end of the egg holding village 57 is pushed upward by an operating cam (not shown). Presser foot Z section 56
presses the upper surface of the shelled egg E on the egg receiving part 42.

At this time, the rear end of the egg-breaking blade 54 is lowered by the operating cam,
The blade part of the egg-breaking blade 54 rises due to the action of the spring, and the egg-receiving part 42
, 42 and hits the lower surface of the shell egg E, breaking the shell.
Thereafter, the force 2 shifter 53 of the lever 48 is pushed down by the operating cam, and the pivot shafts 52 of the levers 48, 49 reach a position below the line connecting the pivot pins 50, 51 of the cross levers 46, 46, and are expanded laterally. As a result, the egg shells cracked by the egg-breaking blade 54 are separated left and right while being held between the left and right egg receiving parts 42, 42 and the egg presser part 56, and the egg yolk and white are separated from the lower end of the crack. Egg yolk and albumen are collected by flowing down into the container 61. Among the egg yolk and albumen contained in the egg yolk and albumen separation container 61, the egg yolk Ea is stored at the bottom, and the albumen above this comes out from the opening 66 of the egg yolk and albumen separation container 61 and flows downward.

This egg white flows into an egg white collection container 62 placed directly below the egg yolk and albumen separation container 61 and is collected. In addition,
The egg yolk/egg white separation container 61 that separates the egg white from the yolk includes:
After receiving the egg yolk and albumen flowing down after the egg is broken, the pin 69 is pushed by a cam (not shown) and tilted slightly toward the opening 66, whereby all of the albumen flows out from the closing section 66 and the yolk and albumen are separated. be done. When the pin 69 finishes passing through the cam, the spring 71 returns the egg yolk/white separation container 61 to its initial horizontal position. In this way, the egg yolk and albumen are collected from the broken eggshell, but depending on the position where the egg-breaking blade 54 hits and the degree of cracking of the eggshell, the egg white and the egg-breaking blade 54 may be recovered.
A part of the egg yolk that has been cut by step 4 may remain inside the eggshell.

However, in the present invention, the removal area C of eggs remaining in the eggshell in the section where the egg breaking machine 1 rotates around the shaft 4 via the collection area B.
In this step, the egg white or egg yolk remaining in the eggshell is removed.

That is, when one egg-breaking mechanism 11 is followed, when this egg-breaking mechanism 11 enters the exclusion area C, the moving nozzle 18
The sliding member 17 at the rear of the spring 23 is moved by the guide bar 24.
The movable nozzle 18 moves forward along the guide shaft 16 while manipulating it, and the moving nozzle 18 also moves forward via the spring 26, so that its tip is between the egg receiving parts 42, 42 of the egg breaking mechanism 11 and the egg holding part 56. The eggshells Eb and E are separated from each other to the left and right.
During the period b, enter as shown in Figure 4. On the other hand, the roller 34 at the base of the swinging pestle 31 of the air supply mechanism 29, which moves in synchronization with the rotation of the shaft 4, is pushed up by the cam rail 33, and the air supply nozzle 28 at the tip is brought into close contact with the valve seat 27 of the connector 21. At the same time, the operating piece 35c of the air supply valve 35
is pushed by the swinging punch 31 to open the valve, and pressurized air is supplied from the air supply nozzle 28 into the subsequent tool 21 through the air passage 36 in the shaft 4, the hose 37, the air supply valve 35, and the hose 40. , from this connector 21 to the flexible tube 22
Pressurized air is sent to the moving nozzle 18 through. In this case, the air injection holes 19, 19 at the tips of the movable nozzles 18 are bored toward the inner top surfaces of the eggshells Eb, Eb held by the egg-breaking mechanism 11. ，
The pressurized air injected from No. 19 is blown to the deepest part of the inner surface of the eggshells Eb, Eb, and therefore the albumen or egg yolk remaining on the inner surface of the eggshells Eb, Eb is blown away and flows out through the cracks, and is directly below it. 5 egg yolk and white separation containers 61, and the overflowing egg whites are collected in an egg yolk and white separation container 6.
The egg whites flow down and are collected from the closed part 66 of No. 1 into the egg white collection container 62 located directly below it. In this way, while the chain 100 constituting the egg-breaking machine conveyor passes through the exclusion zone C in the section where it rotates at an acute angle around the axis 4, the remaining egg white or egg yolk is removed, and this removal action is carried out by the egg-breaking mechanism that rotates one after another. 11,11・
. . . is performed by the corresponding air supply mechanism 29.

The egg yolks and egg whites collected as described above are stored in the collection container 1.
While the eggs 2 pass through the inspection area D of the egg breaking machine 1, a visual inspection is carried out by an inspector, and the egg yolks and albumens other than defective eggs are collected into containers or chutes at appropriate locations.

When the movable nozzle 18 moves forward, if the egg held by the egg-breaking mechanism 11 is not cracked and is held as a shelled egg, the tip of the movable nozzle 18 will touch the side surface of the shelled egg E. However, at this time, the tip of the movable nozzle 18 has a shell g.
Even if it hits EE, it remains in that position only by carrying the spring 26, and does not break through the shell egg E.

When the shape of the guide bar 24 enters the retreating region, it follows the restoring force of the spring 23 on the guide shaft 16 and retreats, returning to its original position. Eggshell Eb held by the egg-breaking mechanism 11
, Eb or unbroken eggs are removed by appropriate means in the eggshell removal area F and returned to the delivery area A.

As explained above, the present invention provides a movable nozzle having an air injection hole at the tip between the cracks of the divided eggshell which is held in a gripped state after the shell is cracked and the yolk and albumen are collected by gravity. By inserting the nozzle and continuously blowing pressurized air toward the top of the inner surface of the eggshell from the air injection hole at the tip of the nozzle, the egg white or egg yolk that remains inside the eggshell is forcibly removed, making it possible to break the egg. Even if the condition is not perfect and the egg white or egg yolk remains in the eggshell, it can be completely discharged, and the recovery efficiency of the albumen and yolk can be significantly improved, and the yield can be greatly improved. Furthermore, according to the device of the present invention, if the moving nozzle is blocked in its path, it will stop moving against the seal, so even if cracked eggs occur due to a mistake in cracking the shell, the tip of the moving nozzle will It won't break the shell. Furthermore, the removal mechanism including a moving nozzle is
Since the device is installed around the rotating shaft of the egg-breaking machine conveyor, it is possible to continuously remove residual eggs even though the number of installations is small, and it is easy to synchronize with the egg-breaking machine conveyor, so it is reliable. Various effects can be obtained, such as being able to provide a powerful exclusion function. Note that the configuration of each part in the present invention is not limited to the illustrated embodiment, and design changes may be made arbitrarily without departing from the technical idea of the present invention.
