Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressurized air injection device, and more particularly to a pressurized air injection device suitable for use in a pressurized air injection section 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., this machine automatically cracks shelled eggs, extracts the yolk and white, and separates the yolk and white if necessary and collects them separately. Egg machines 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 collected in its entirety, which may reduce the yield of recovered eggs.

For this reason, after the egg is broken and the yolk and albumen are collected by gravity, a movable nozzle with an air injection hole at the tip is inserted between the cracks of the divided eggshell that is being held. , a pressurized air injection device suitable as a residual egg fluid removal device that removes albumen or egg yolk that remains inside the eggshell 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. was devised by the inventor.

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. The steps of breaking eggs, collecting egg yolk and albumen, and removing eggshells after removing residual egg fluid are performed, and the removal of residual egg fluid using the nozzle must also be performed at some point during the above steps,
It is extremely uneconomical to install an air supply source for each of the egg-breaking mechanisms, and therefore it is necessary to supply pressurized air only for a certain period of time. It is difficult to blow out pressurized air instantly after insertion, and there may be a time lag before it blows out.
Otherwise, there was a problem of unnecessary ejection.

In view of this, the present invention has been devised for the purpose of providing a pressurized air injection device in which pressurized air is ejected the moment the pressurized air injection nozzle advances to a predetermined position.

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

Except for one of them, 6, a toothless guide sprocket is used.

One shaft 4 on the rear side of the egg breaking machine 1 is spaced apart from the other shaft 5 so that the chain 10 can be rotated at an acute angle there.

Therefore, the chain 10 is wound in a rectangular shape with a trapezoidal planar shape, and the area between the shafts 2 and 3 on the front side is the delivery area A where shell eggs E are supplied, and the area between the shafts 2 and 4 is where the egg yolk is supplied. The egg white recovery area B is defined as the area rotated at an acute angle by the shaft 4, and the area C for eliminating residual egg fluid in the eggshell, to which the present invention is applied, is the area between the axes 4 and 5 where the egg white is collected into the container. The inspection area D is for egg yolk and albumen, and the turning range of the shaft 3 is defined as an area F for excluding unbroken eggs and excluding eggshells.

FIG. 2 shows the present invention in the case where pressurized air is injected into the removal mechanism 12 which blows out and collects the egg white or egg yolk remaining in the eggshell with pressurized air in the egg liquid removal area C remaining in the eggshell of the egg breaking machine 1. A specific example is shown.

The movable nozzle 22 has pressurized air injection holes 23 opening slightly diagonally upward on both sides of its front end, and tongues 24 protruding 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 1. ing. Furthermore, the sliding member 19 and the movable nozzle 22
A compression spring 33 is interposed between the movable nozzle 22 and the boss portion 32 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.
The vertical sliding shape of the frame 17 allows the entire frame 17 to be swung from the horizontal position shown in FIG. 2 to a forward tilted position at a required 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.
The egg receiving part 36 is attached above and has an egg receiving part 36 at its tip on which a shelled egg is placed in a horizontal position.
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.
It is designed to hold the shelled egg 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 concave shape with the lower half down and has a bottom area suitable for just storing one egg yolk Ea, and an opening 14A is cut in the side wall from slightly below the height of the egg yolk Ea to the upper end. has been done. The shape of the opening 14A is approximately V, which widens as it reaches the upper end of the egg yolk/white separation container 14.
It is said to be a letter.

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.

In FIG. 1, reference numeral 42 denotes a delivery conveyor, and the end of a supply conveyor 43 that transfers and supplies washed shell eggs E in double rows in the delivery area A of the egg breaking machine 1;
It is provided between the chain 10 constituting the egg breaking machine conveyor and runs in the same direction at the same speed as the chain 10,
After the shelled eggs E are once transferred from the end of the supply conveyor 43 to the delivery conveyor 42, they are delivered to the egg breaking mechanisms 11, 11, . . . of the egg breaking machine conveyor under 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 43, and once transferred from the end thereof onto the delivery conveyor 42, and the shell eggs E placed in a horizontal position on this delivery conveyor 42 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 10 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 hangs from 4A and flows downward to the 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 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 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 in the egg-liquid removal area C remaining in the eggshell in the section rotating around the shaft 4 via the recovery area B of the egg-breaking machine 1. That is, one egg breaking mechanism 11
If you follow this, you will see that the removal mechanism 12
5 and 35, the rear end is lowered as shown in FIG. 2, and the valve seat 39 of the pressure air receiving connection part 38 is joined to the nozzle member of the pressure air supply nozzle of the pressure air supply system (not shown), and the pressure air is supplied. A valve in the system opens and pressurized air is supplied into the air passage 25 in the guide shaft 18. However, at this time, the movable nozzle 22 has not moved forward yet, so the opening 27 in the block 20 at the end of the air passage 25 of the guide shaft 18 is sealed by the circumferential surface of the movable nozzle 22.
There is no blowing out of air.

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 tip touches 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.

The chain 10 that constitutes the egg breaking machine conveyor in this way
Exclusion area C of the section where turns around axis 4 at an acute angle
During the passage, residual albumen or egg yolk is removed, and this removal action is carried out by the successive egg-breaking mechanism 1.
Pressurized air is ejected every time 1, 11, . . . by the corresponding action described above.

When the one egg-breaking mechanism 11 reaches the time when it passes the exclusion area C, the rear part of the exclusion mechanism 12 is lifted up by the guide rails 35, 35, and the pressure air receiving connection 38 is connected 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 remains in that position, and the cushioning effect of the tongue piece 24 at the tip prevents the shell egg E from being broken through. 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, by using the same removal mechanism 12 as described above (however, the pressurized air supply system is not required) in the eggshell removal area, it is possible to remove the eggshells or unbroken eggs held by the egg-breaking mechanism 11. can.

In the illustrated embodiment, the block 20 includes a moving nozzle 2.
2 is inserted and the opening 27 of the air passage 25 of the guide shaft 18 is opened and closed on the circumferential surface of the movable nozzle 22. However, as another example, as shown in FIG. A branch pipe 22A is provided at the opening 27.
is opened on the side of the block 20 to connect the branch pipe 22A.
It may be formed so that it can come into close contact with the communicating hole 28' at the tip of the nozzle, so that when this comes into close contact, pressurized air is supplied to the air passage 26 of the movable nozzle 22 through the branch pipe 22A.

In the above explanation, the case where the present invention is used for supplying and discharging pressurized air to the egg-removal mechanism in the eggshell of an egg breaking machine has been shown, but pressurized air may also be injected at a predetermined time for other purposes. It goes without saying that the present invention can be applied to any necessary device, and the configuration of each part is not limited to the illustrated embodiment.

As explained above, the pressurized air injection device according to the present invention intermittently ejects pressurized air supplied from the pressurized air supply side from the nozzle, and the nozzle is aligned with the guide shaft provided parallel to the nozzle. A movable nozzle is movable in the axial direction and has an air passage inside, and the air passage in the guide shaft is formed to be able to freely supply pressurized air from a pressurized air supply source, and the movable nozzle is arranged at a predetermined pressurized air injection position. Since the air passage inside the movable nozzle and the air passage within the guide shaft are configured to communicate with each other when the movable nozzle moves to the pressurized air injection position, pressurized air is ejected at the moment the movable nozzle moves to the pressurized air injection position, making it possible to accurately control the injection timing. It is not necessary to eject the air before reaching the injection position, and an excellent effect can be obtained without wasteful consumption of pressurized air.
