Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressurized air supply device, and more particularly to a pressurized air supply device suitable for use in a pressurized air supply 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., it automatically cracks shelled eggs, extracts the yolk and albumen, and separates the egg yolk and albumen as needed and collects them separately. Egg breaking 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. are allowed to fall naturally and are 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. It is conceivable that the albumen or egg yolk that remains inside the eggshell can be removed by blowing pressurized air toward the top of the inner surface of the eggshell from the air injection hole at the tip of this nozzle.

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 at one time. Although this can be easily achieved by using rotary valves for rotating objects, it is extremely difficult to supply air only at the necessary times to objects that are rotated by a conveyor as mentioned above, and it is still difficult to supply air to objects that rotate using a conveyor. In reality, the removal of residual egg fluid inside the eggshell has not been achieved.

The above is not limited to the removal of egg fluid remaining in the eggshell, but the same can be said to any application that requires supply of pressurized air when an object to be removed moves to a certain position.

In view of this, the present invention supplies pressurized air by connecting the pressurized air source and the air injection unit only when necessary, and disconnects and cuts off the pressurized air from the air supply source when the supply is cut off. The purpose of this invention is to provide a pressurized air supply device that can obtain the desired air pressure.

receives the egg yolk and albumen flowing down after the egg is broken, and then tilts toward the opening 66 by a cam (not shown), whereby all of the albumen is separated from the yolk Ea and flows out.
Upon leaving the cam, the egg yolk/white separation container 62 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
1, the rear end is lowered as shown in FIG.
9, then the connection 2 for pressurized air supply
The operating rod 33 protruding from the valve seat 32 of No. 1 is inserted into the nozzle member 39 of the pressurized air supply nozzle 38, the valve body 41 is pushed against the valve spring 42, and the lower surface of the nozzle member 39 is opened. Air passage 34 of shaft 4, air distribution chamber 36, branch passage 37, air chamber 4
0, pressurized air is supplied to the movable nozzle 18 through the nozzle 38, the passage 23 of the guide shaft 16, and the flexible tube 24.

On the other hand, prior to this, the sliding guide 17 at the rear of the movable nozzle 18 is moved by the spring 25 by the guide bar 27.
The movable nozzle 18 moves forward along the guide shaft 16 while being bent, and at the same time, the movable nozzle 18 also moves forward via the spring 29, and its tip touches the egg receiving part 4 of the egg breaking mechanism 11.
As shown in FIG. 7, it enters between the eggshells Eb, Eb, which are sandwiched between the eggs 4, 44 and the egg presser 58 and spaced apart from each other to the left and right.

In this case, the air injection holes 19, 19 at the tip of the movable nozzle 18 are bored so as to face the inner top surfaces of the eggshells Eb, Eb held in the egg-breaking mechanism 11. Pressurized air is blown to the innermost part of the eggshells Eb and Eb, and the albumen or yolk remaining on the inner surfaces of the eggshells Eb and Eb is blown away and flows out through the cracks, and the yolk that is directly below it is blown away. The egg whites are collected in the egg white separation container 62, and the overflowing egg whites flow down from the opening 66 and are collected in the egg white collection container 63.

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.
1, 11, . . . , the pressurized air is supplied 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 rail 31, and the pressure air receiving connection part 21 is connected to the pressure air supply nozzle of the pressure air supply system. 38, the valve body 41 is separated from the valve spring 4.
It is pushed up by the force of 2 and comes into pressure contact with the lower surface of the nozzle member 39, stopping the supply of pressurized air.

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 moving nozzle 18 touches the side of the shelled egg E, but at this time, even if the tip of the moving nozzle 18 touches the shelled egg E,
It remains in that position only by bending the spring 29, and does not break through the shell egg E. 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.

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 above explanation, the present invention is used for supplying and discharging pressurized air to the egg-removal mechanism in the eggshell of an egg-breaking machine, but pressurized air may 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 present invention provides a system for intermittently supplying pressurized air from a pressurized air supply side to a pressurized air receiving side such as a pressurized air injection nozzle, in which a frame is supported by a support member so as to be vertically swingable. a pressurized air receiving member such as a pressurized air injection nozzle supported on the frame; an air receiving connection portion provided on the frame and capable of closely fitting into an air supply connection portion on the compressed air supply side; and the frame. an actuating means for swinging the pressurized air supply connection so that it comes into close contact with the pressure air reception connection when pressurized air is supplied; an air supply valve that opens when the frame swings; and an air supply valve that opens when the frame swings; Since the connection part is provided with a pressure air supply system that supplies pressurized air from the pressure air source via the air supply valve, the pressure air supply side and the receiving side are arranged in a circular manner, as shown in the illustrated embodiment. Pressure air can be supplied only when it is needed, even if the other side moves on an arbitrary trajectory, and the air supply valve is opened when the pressurized air is connected to the receiving side, and the air supply valve is opened at the required time. Since pressurized air is sent only to the cylinder, it is possible to make effective use of the compressed air. In addition, in the present invention, since the pressure air supply nozzles of the pressure air supply system are arranged only around the axis, the structure of this part does not become complicated, and the appearance becomes plain and there is a risk of failure. There are various excellent effects such as being able to reduce the amount of water used.
