Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic egg breaking machine that automatically breaks eggs and takes out and collects egg yolk and albumen.

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

By the way, conventional egg-breaking machines have been provided with an egg-breaking machine conveyor that carries out each process of cracking eggs and recovering egg yolk and albumen. Since it is formed in a rectangular arrangement, the installation space for the egg breaking machine is large, and there is a disadvantage that it wastes space. It is necessary to secure a space for the inspector who inspects the egg yolk and albumen, and therefore it is necessary to place the egg breaking machines with a wide distance between them, making effective use of the space in the building. There was a problem that it was difficult to do.

Therefore, the applicant constructed the third section of the egg breaking machine conveyor, which has four sides and is disposed so as to be freely movable, to be oblique in the direction in which the fourth section becomes shorter. The installation space can be used effectively by deploying inspectors in the space, and since the front side corner of the inspection area is at an acute angle, the turning section can be used to spray pressure air. We have developed an automatic egg-breaking machine that removes the egg yolk and albumen remaining in the eggshell, contains this removed egg liquid, which is inspected by inspectors, and removes it if it is a defective egg.

According to the above configuration, the problem of installation space could be solved, but for example, when a rotten egg or a bloody egg is broken, residual egg liquid remaining in the eggshell is also removed by compressed air in front of the inspection area. Because it is excluded by
The egg fluid is scattered into the cup of good quality egg yolk and albumen, and the good quality egg yolk and albumen mixed with the egg fluid of rotten eggs and bloody eggs must also be removed in the inspection area, which reduces the recovery yield of egg yolk and albumen. The drawback was that it decreased significantly.

In view of this, the present invention has an endlessly arranged egg-breaking machine conveyor that does not waste space, and also arranges each area of the egg-breaking machine conveyor in the most efficient arrangement for the egg processing process. , an automatic egg-breaking method that can improve the recovery yield of high-quality egg yolk and albumen by eliminating the contamination of egg shell fragments and other foreign matter, as well as the contamination of egg fluid from rotten eggs and bloody eggs, into the collected egg yolk and albumen. This was done for the purpose of providing an opportunity.

Hereinafter, the present invention will be explained with reference to embodiments shown in the drawings.

As schematically shown in FIG. 1, the egg breaking machine conveyor K includes a first shaft 1, a second shaft 2 standing upright at a required distance from the shaft 1, and the first shaft 1, A third shaft 3 stands at a required distance from the second shaft 2 in a direction perpendicular to the imaginary line connecting the second shafts 1 and 2, and these second and third shafts 2. , 3 to the sprockets 5, 6, 7, 8 on each axis of the fourth axis 4, which is erected at a required interval from the third axis 3 in a direction forming an obtuse angle with respect to the imaginary line connecting them. It has an endlessly wound chain 9, and an egg-breaking machine conveyor K is constituted by this chain 9 and egg-breaking machine grooves 11, 11, . . . attached to this chain 9 at regular intervals. There is.

The imaginary line connecting the fourth axis 4 and the first axis 1 is arranged parallel to the imaginary line connecting the second axis 2 and the third axis 3, and is formed to be long, The distance between the third axis 3 and the fourth axis 4 runs diagonally when viewed from the plane.

The sprockets 5 to 8 are sterile guide sprockets except for one sprocket 5, and a rotational driving force is transmitted to the shaft 1 having the toothed sprocket 5 from a drive source (not shown). The egg machine conveyor K is configured to move in the direction of the arrow in FIG.

A first section between the first shaft 1 and the second shaft 2 is defined as a delivery area A for shell eggs, and a second section between the second shaft 2 and the third shaft 3 is defined as a delivery area A for shell eggs. The section is designated as the yolk and albumen collection area B, where the eggs are broken and the yolk and albumen are collected from the eggshell.The third section that slopes from the third axis 3 to the fourth axis 4 is used for inspection of the collected yolk and albumen. The area C is designated as a region C, and the turning section that turns at an acute angle along the fourth axis 4 is designated as the residual egg fluid removal region D in the eggshell, which eliminates the egg fluid remaining in the eggshell. The fourth section between the axis 1 and the axis 1 is defined as a region F in which unbroken eggs and broken eggshells are removed.

In the delivery area A, which is the first section of the egg-breaking machine conveyor K, there are egg-breaking machine grooves 11, 11 installed at a constant interval from the end of the egg supply conveyor 10 to the egg-breaking machine conveyor K. A delivery conveyor KA that delivers the eggs E stably and at high speed to ... is arranged parallel to the egg-breaking machine conveyor K in the delivery area A so as to move at the same speed as the egg breaker conveyor K. It is provided as a section for delivering eggs to the egg breaking mechanisms 11, 11, . . .

In the egg yolk and albumen collection area B, which is the second section, the egg yolk and albumen are discharged from the eggshells that have been broken by the egg breaking mechanisms 11, 11, etc. It is provided as an area where only the albumen is received and the albumen is collected in the albumen cup below it.

The inspection area C, which is the third section, is an area where the egg yolk and albumen collected from the eggshell are subjected to visual inspection, and while the cup moves through this inspection area C, defective eggs and foreign objects (eggshells) are detected. It is provided as a section to be discarded by tilting the cup.

The residual egg liquid removal area D in the eggshell, which is a section that turns at an acute angle, is provided as a section in which the egg liquid remaining in the eggshell is recovered by, for example, blowing pressurized air.

In the removal area F, which is the fourth section, the egg breaking mechanism 1
It is provided as a section for excluding eggshells or unbroken eggs held in 1, 11, . . .

The egg breaking machine conveyor K having each of the above areas forms an obtuse angle of 90° or more at the starting end of the inspection area C after the turning section, and an acute angle at the next corner, so that the inspection area C between A void space G is formed on the outside of the part, so that when an inspector is located in this void space and performs inspection work, it will not interfere with the adjacent egg breaking machine.
The installation space for the egg breaking machine can be used effectively.

Next, the residual egg fluid removal mechanism 12 in the eggshell used in the residual egg fluid removal region D includes a second
As shown in the figure, the device is installed on the upper part of a support member 13 fixed on the outer surface side of the chain 9, and on the side of this support member 13, there is a container for separating the egg yolk and albumen flowing out from the eggshell during egg breaking and for collecting the albumen. 14 and 15 are attached, and these egg-breaking mechanism 11, ejection mechanism 12, and containers 14 and 15 are moved together as the chain 9 moves.

The removal mechanism 12 includes a guide shaft 18 fixed in a direction perpendicular to the chain 9 to a frame 17 whose lower front end is pivotally supported on the support member 13 so as to be tiltable forward by a shaft 16; A pressure air supply block 20 is fixed to the front end of the guide shaft 18, and the rear end is inserted into and supported by the sliding member 19, and a The movable nozzle 22 is airtightly inserted and supported in the through hole 21 of the block 20, and the movable nozzle 22 has pressurized air injection holes 23 opened slightly diagonally upward on both sides of the front end. A tongue piece 24 is provided to protrude forward and downward. Note that this tongue piece 24 functions as a buffer when used to push down and remove unbroken eggs.

Both the guide shaft 18 and the sliding nozzle 22 are made of a pipe material, for example, and have air passages 25 and 26 inside in the axial direction.
The end of the nozzle 22 is opened at the inner circumferential surface of the through hole 21 of the block 20, and this opening 27 is connected to the movable nozzle 22.
It is designed to be sealed by the circumferential surface of the

The movable nozzle 22 moves forward and the injection holes 23, 23 at the tips of the movable nozzle 22 move to a predetermined ejection position (second
When the opening 27 is placed in the position shown by the chain line in the figure
A communication hole 28 is opened at a position corresponding to the
This communication hole 28 is the air passage 2 in the moving nozzle 22.
It is connected to 6. Therefore, the moving nozzle 22
When the communication hole 28 does not match the opening 27, air is blocked at the opening 27.

A compression spring 29 is interposed on the outer periphery of the guide shaft 18 and springs between the front inner surface of the frame 17 and the sliding member 19, and normally causes the sliding member 19 to retreat to the position shown in FIG. , this is given the habit of pulling back the movable nozzle 22 which is prevented from coming off via a spring 30, and the rear surface of the sliding member 19 is brought into contact with a guide bar 31 disposed on the egg breaking machine. There is. A compression spring 33 is interposed between the sliding member 19 and the boss portion 32 of the movable nozzle 22 so that the movable nozzle 22 can be returned independently.
Therefore, when the sliding member 19 moves forward due to the shape of the guide bar 31, the sliding member 19 moves forward on the guide shaft 18 by bending the compression spring 29, and as the sliding member 19 moves forward, the compression spring 33 The movable nozzle 22 is moved forward via.

A roller 34 is pivotally supported at the rear end of the frame 17, and this roller 34 is sandwiched between an upper and lower pair of guide rails 35, 35.
Due to the vertically folded shape of the frame 5, the entire frame 17 can be swung from the horizontal position shown in FIG. 2 to a forward tilted position at a predetermined angle. and the frame 1
An egg-breaking mechanism 11 is attached to the front upper part of the egg-breaking mechanism 7. This cleavage mechanism is publicly known (Jikko 56-
No. 7178) is used, so a detailed explanation thereof will be omitted, but the outline will be as follows.
It is attached above and has an egg receiving part 36 at its tip on which a shelled egg is placed in a horizontal position, and this egg receiving part 3
6 consists of a pair of left and right arm rods, which are supported so that they can move toward and away from the left and right, and are normally brought close together by a spring.
The egg in the shell is held in cooperation with a presser member (not shown), and when breaking the egg, the knife 37 is swung upward from below to break the egg, and the egg receiving part 36 opens and the yolk and albumen flow down. It was made to do so.

The air receiving connector 38 has a valve seat 39 recessed in the shape of an inverted cone on the lower surface, and an operating rod 40 for opening a valve of a pressure air supply system (not shown) projects downward from the valve seat 39. .

The egg yolk/white separation container 14 has a bottom area that is suitable for storing one egg yolk Ea, and has an opening 14A cut in the side wall from slightly below the height of the egg yolk Ea to the upper end. It is set up. The opening 14A has a substantially V-shape that widens as it reaches the upper end of the egg yolk/white separation container 14.

The free end 15A of the egg white collection container 15 is received by a guide bar 41. This guide bar 41 once moves each container 14, 15 to the egg-breaking mechanism 1 until it reaches the collection area B where the egg yolk and albumen are received.
The heights are different so that it can be tilted to a position close to 1 and then kept in a horizontal state, and the free end 15A is lowered and tilted forward at the position where the collected egg yolks and egg whites are collected in another container or chute. , the height is adjusted in the vertical direction so that it can be taken out to each chute etc. depending on the difference in the tilt position.

The delivery conveyor KA in FIG. 1 connects the end of the supply conveyor 10 that transfers washed shelled eggs E in a return row in the delivery area A of the egg-breaking machine and the chain 9 that constitutes the egg-breaking machine conveyor. A conveyor which is provided between the chain 9 and which runs in the same direction at the same speed as the chain 9 and delivers the shell eggs E from the end of the supply conveyor 10.
After being transferred to the KA once, the eggs are delivered to the egg-breaking mechanisms 11, 11, . . . of the egg-breaking machine conveyor in a stationary state with no relative speed difference.

Next, the operation of the above embodiment will be explained.

The washed shell eggs E are sent on the supply conveyor 10, and once transferred from the end to the delivery conveyor KA, and the shell eggs E placed horizontally on this delivery conveyor KA are moved at the same speed as this. The eggs are delivered onto the egg holding section 36 of the egg breaking mechanism 11 of the egg breaking machine conveyor that moves in the same direction.

The shelled egg E delivered onto the egg receiving part 36 of the egg breaking mechanism 11 is broken by the knife 37 in the process of moving as the chain 9 moves, and the egg holding part 36 opens left and right to release the egg yolk. The egg white flows down into the egg yolk and albumen separation container 14 and is collected.

Of the egg yolk and albumen that have entered the egg yolk and albumen separation container 14, the egg yolk Ea is stored at the bottom, and the egg white above this is stored in the opening 1 of the egg yolk and albumen separation container 14.
It overflows from 4A and flows downward into egg white collection container 1.
It will be collected within 5 days. In addition, egg yolk and white separation container 14
receives the egg yolk and albumen flowing down after the egg is broken, and then tilts toward the opening 14A side by, for example, a cam (not shown), whereby all of the albumen is separated from the yolk Ea and flows out, and when it leaves the cam, it enters the yolk and albumen separating container. 14 is returned to its initial position.

The containers collected as described above are in the inspection area C.
During the passage, rotten eggs and bloody eggs are inspected by an inspector or other inspection means, and for normal eggs, each container 14, 15 is tilted by a cam (not shown) at a predetermined position, and the egg yolk and albumen are collected separately onto a collection gutter. It is discharged. In the case of abnormal eggs, they are discharged onto the collection gutter for abnormal eggs by the inspector's operation.

The egg yolk and albumen are recovered from the eggshell that has been broken as described above.
Some of the yolk that has been cut off may remain inside the eggshell.

In the above case, the egg white or egg yolk remaining in the eggshell is removed at the egg fluid removal area D remaining in the eggshell, which is a section that passes through the inspection area C of the egg breaking machine and rotates over 90 degrees around the axis 4. . That is, when one egg-breaking mechanism 11 is followed, the rear end of the ejection mechanism 12 is lowered by the guide rails 35, 35 as shown in FIG. It is joined to the nozzle member of the pressure air supply nozzle of the air supply system, and when the valve of the pressure air supply system opens, the air passage 2 in the guide shaft 18
Pressurized air is supplied within 5. However, at this time, the movable nozzle 22 has not moved forward yet, so at the end of the air passage 25 of the guide shaft 18, the opening 27 in the block 20 is sealed by the circumferential surface of the movable nozzle 22, and the air is ejected. doesn't happen.

Next, the sliding guide 19 at the rear of the movable nozzle 22
moves forward along the guide shaft 18 while bending the spring 33 by the guide bar 31, and at the same time, the movable nozzle 22 also moves forward via the spring 33, and its cut end is connected to the egg receiving part 36 of the egg breaking mechanism 11 and the egg presser. It enters between the eggshells that are sandwiched between the eggshells and the eggshells that are separated from each other on the left and right.

When the moving nozzle 22 advances to a predetermined position,
The communication hole 28 and the opening 27 in the block 20 match, and at the same time the pressurized air that was being supplied into the guide shaft 18 flows through the opening 27 and into the communication hole 2.
8. The air is injected from the injection holes 23, 23 through the air passage 26, and is blown onto the deepest part of the inner surface of the left and right eggshells held in the egg-breaking mechanism 11, thereby blowing away the albumen or egg yolk remaining on the inner surface of the eggshell. The egg whites flow out through the cracks and are collected in the egg yolk and albumen separation container 14 located directly below the cracks, and the overflowing albumen flows down and is collected in the egg white collection container 15 through the opening 14A.

In this way, while the chain 9 constituting the egg breaking machine conveyor passes through the exclusion zone D in the section where it turns around the axis 4 at an acute angle, the remaining albumen or egg yolk is removed,
This elimination action is caused by the successive egg-breaking mechanism 11, 1.
Pressurized air is ejected by the above-mentioned action corresponding to each time.

When the one egg-breaking mechanism 11 reaches the time when it passes the exclusion area D, the rear part of the exclusion mechanism 12 is lifted by the guide rails 35, 35, and the pressure air receiving connection 38 connects to the pressure air supply of the pressure air supply system. supply of pressurized air is stopped.

Note that when the movable nozzle 22 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 22 moves forward.
The tip of the movable nozzle 22 touches the side of the shelled egg E, but at this time, the egg is held within the recess of the egg receiving part 36, so even if the tip of the moving nozzle 22 touches the shelled egg E,
Only by bending the spring 33, the egg does not fall and stays at that position, and the cushioning effect of the tongue piece 24 at the tip prevents the egg from breaking through the shelled egg E. When the shape of the guide bar 31 enters the retreating region, it follows and retreats due to the restoring force of the spring 29 of the guide shaft 18.
Return to original position.

Therefore, in the eggshell removal area F, the same removal mechanism 12 as above is used (however, the pressurized air supply system is not required).
By making the guide bar 31 partially protrude forward as shown by 31A in FIG. 1, the eggshell or unbroken egg held by the egg-breaking mechanism 11 can be removed.

Note that the residual egg fluid removal mechanism 12 described above is merely an example, and it goes without saying that other mechanisms may be used.

Therefore, according to the present invention, from delivery of eggs,
While it is possible to effectively provide an area suitable for performing all tasks such as breaking eggs, collecting and inspecting egg yolks and albumens, removing and collecting residual egg fluid, and removing eggshells, it is possible to effectively utilize the installation space, and it is possible to use the limited space. Many egg breaking machines can be installed in a small space.

In addition, after normal eggs and abnormal eggs are sorted in the inspection area, residual egg fluid is removed in the next turning section, so that residual egg fluid in the eggshells of abnormal eggs is not scattered into the recovered egg fluid of normal eggs. Therefore, the recovery yield of normal egg fluid can be significantly improved.

Furthermore, since the residual liquid removal area in the eggshell in the turning section after the inspection area turns at an acute angle of less than 90 degrees, the time required for the egg-breaking machine conveyor to revolve around the shaft is long, and therefore the removal of egg liquid in this section is difficult. It has various excellent effects such as being able to take a longer period of time and ensuring the removal of egg fluid.
