I'm preventing.

Next, the operation based on the configuration of the embodiment of the present invention will be described below. The power of the automatic egg breaking device 1 is turned on, and the rotating disk drive motor 2d and the rotary blade drive motor 5k are driven.

When the rotating disk driving motor 2d is driven, the driving force of the rotating disk driving motor 2d is transmitted to the rotating shaft 2a via the motor side gear 2c and the driving gear 2b, and the rotating shaft 2a is provided at the center. The turntable 2 rotates.

The rotating blade 5 provided at the lower end of the rotating shaft 5a is transmitted to the rotating shaft 5a via i and the driven pulley 5d, and rotates.

The egg a to be broken is mounted on the egg receiving hole 3 of the rotating turntable 2. In the egg receiving hole 3 on the side where the egg a is mounted, the upper egg presser 4 is flipped upward by the cam 4f provided on the lower surface of the flip-up board 4e, and the egg a is mounted in the egg receiving hole 3. The upper egg presser 4 does not interfere.

That is, at this point, the cam 4f provided on the lower surface of the flip-up board 4e is
The operating piece 4d provided on the rear end side is pressed downward, so that the operating rod 4b is pivoted upward with the bearing 4c as a fulcrum, and the egg pressing ring 4a is pivoted upward to be repelled and lifted. There is no hindrance when attaching a to the egg receiving hole 3.

When the egg a to be broken is mounted on the egg receiving hole 3 of the rotating turntable 2, the egg receiving hole 3 on which the egg a is mounted rotates together with the rotation of the turntable 2, and the rotary blade 5 rotates. Move toward the place where you are.

At this time, since the cam 4f provided on the lower surface of the flip-up board 4e has disappeared on the side where the rotary blade 5 is rotating, the cam 4f has caused the operating piece 4d on the rear end side to face downward. The operating rod 4b pressed against the rotating blade 5
The pressing by the cam 4f is released during the movement toward the side, and the egg pressing ring 4a on the front side of the operating rod 4b, which has been repelled upward by the spring 4g, is rotated downward to provide an egg receiving hole. 3. Hold the upper side of egg a attached to 3.

In this manner, the egg a approaches the rotary blade 5 in a state where the upper side of the egg a is pressed by the egg pressing ring 4 a attached to the egg receiving hole 3. The rotary blade 5 is mounted so as to cut slightly below the lower surface of the egg receiving hole 3, and each egg mounted in the egg receiving hole 3 projects only slightly below the lower surface of the egg receiving hole 3. A part of the outer periphery of the cut portion, for example, about one third of the circumference is cut and a cut b is made.

By the way, the inside diameter of the egg receiving hole 3 is equal to that of a normal egg a.
Is smaller than the diameter on the minor axis side of the elliptical sphere, the lower side of the mounted egg a projects downward from the lower surface of the egg receiving hole 3. At this time, the diameter of the egg a protruding from the lower surface of the egg receiving hole 3 is substantially the same as the inner diameter of the lower surface of the egg receiving hole 3 irrespective of the size of the mounted egg a. Therefore, regardless of the size of the mounted egg a, substantially the same cut b is formed by the rotary blade 5 on the lower side of the egg a mounted in the egg receiving hole 3.

At this time, the guide plate 5 of the rotary blade 5 provided at the distal end of the horizontal arm 5c that can be pivoted in the horizontal direction is used.
Since the arcuate guide 5n of m is moved along the circular outer circumference of the ring 3a of the egg receiving hole 3, the horizontal arm 5c swings slightly left and right, and the rotary blade on the tip side thereof. 5 also moves slightly left and right.

That is, when the egg receiving hole 3 on which the egg a is mounted approaches, the rotary blade 5 moves to the egg receiving hole 3 side and the shell of the egg a on the lower side near the lower surface of the egg receiving hole 3. Start cutting. When the egg receiving hole 3 rotates and starts to approach further, the egg receiving hole 3 starts to move to the opposite side. When the rotation of the egg receiving hole 3 further advances and starts to separate from the rotary blade 5, the rotary blade 5 moves to the egg receiving hole 3 side.

By such a movement, the rotary blade 5 can cut the shell of the egg a near the lower surface of the egg receiving hole 3 while maintaining a predetermined cut depth, and the cut is too deep or too shallow. Never. Also, while cutting the shell on the lower side of the egg a with the rotary blade 5, the upper side of the egg a is pressed by the egg pressing ring 4a, so that the egg a does not rotate and a part of the predetermined outer periphery. A cut b is made by the length of.

A cut b is made in a part of the lower side of the egg a by the rotary blade 5, and when rotated by a certain angle, a support plate 6e provided on the lower side of the turntable 2 and having a shell opening claw 6 in front thereof.
Also rotate together.

That is, an upper operating piece 7c projects downward from the lower surface of the rotating rotary disk 2, while a support disk 6e having a shell opening claw 6 at the front is provided with an interlocking return mechanism 7 at its rear end.
The upper operating piece 7c on the lower surface of the rotating disk 2 which is rotating is in contact with the locking piece 7b at the upper end of the engaging plate 7a. 7b
And rotate it in conjunction with it. Thereby, the support plate 6e provided with the shell opening claws 6 at the front also rotates in conjunction therewith.

The supporting plate 6e which rotates in conjunction with the rotating plate 2
The operating piece 6 provided on the upper surface of the pedestal 6j below the support plate 6e is rotated by the operating roller 6i provided on the front side thereof.
abuts on k. When the operating roller 6i abuts on the operating piece 6k, the connecting operating rod 6m having one end connected to the operating roller 6i rotates around the vertical axis 6n as a fulcrum, and the other end of the rotating connecting operating rod 6m is connected to the connecting beam 6g. When the connecting operation rod 6m rotates, the connecting girder 6g slides toward the rear side of the support board 6e.

A sliding bar 6f is attached to the front of the connecting bar 6g which slides toward the rear side of the support board 6e.
b is attached, and shell opening claws 6 are provided on both left and right ends of the cross beam 6b. For this reason, when the connecting girder 6g moves toward the rear side of the support board 6e, the sliding rod 6f and the horizontal girder 6g move.
The left and right shell opening claws 6 connected to the connecting girder 6g via b also move toward the rear side of the support board 6e.

The left and right shell opening claws 6 are located immediately below the egg receiving hole 3 in which the egg a with the cut b made by the rotary blade 5 is mounted, and are rotated in conjunction with the egg receiving hole 3. The egg a protrudes from the lower surface of the egg receiving hole 3 between the left and right shell opening claws 6 and enters the lower side.

When the left and right shell-opening claws 6 move toward the rear side of the support board 6e, the left and right claw pieces 6a attached to the distal end sides of the inner side surfaces of the left and right shell-opening claws 6 cut the egg a. b.

When the left and right shell opening claws 6 further move toward the rear side of the support board 6e, the operating rod 6h protruding forward at the center of the front end of the support board 6e, and between the left and right shell opening claws 6 The laterally connected connecting rod 6c hits the connecting rod 6c. The connecting rod 6c is connected to the operating rod 6h.
, The left and right shell-opening pawls 6 pivot about the rotation axis on the side surface of the cross beam 6b, and the claw 6a side at the tip thereof turns downward, and the egg below the cut b that the claw 6a cuts into. a
Shell cracks. At this time, since the content of the egg a is viscous and vacuum, even if the lower side of the egg a is broken, it does not immediately flow down.

When the lower side of the egg a is split, the lower end of the engaging plate 7a at the rear end of the support disk 6e rotating in conjunction with the rotary disk 2 is provided on the upper surface of the base 6j below the support disk 6e. The lower end of the engaging plate 7a contacts the lower operating piece 7e, and the lower end of the engaging plate 7a rotates upward about the rotating shaft 7d, and the locking piece 7b of the upper end rotates downward. When the locking piece 7b at the upper end of the engagement plate 7a rotates downward, the engagement between the locking piece 7b and the upper operating piece 7c is released, and only the turntable 2 continues to rotate, and the support board 6e does not rotate.

When the support board 6e stops rotating, the connecting girder 6g, which has been moving toward the rear side of the support board 6e, moves toward the front side by the urging force of the spring 6p, and the slide bar 6f and the horizontal The left and right shell opening claws 6 connected to the connecting girder 6g via the girder 6b also move toward the front side of the support board 6e.

The left and right shell opening claws 6 moving toward the front side
Is relatively released from the operating rod 6h and the pressing thereof is released, so that the left and right shell opening claws 6 that have been rotated obliquely downward return to the original horizontal state by the action of the spring 6d.

Also, the support plate 6e rotated by a certain angle
The operation roller 6i returns to the original state by the biasing force of the spring 6p, and the operation roller 6i that returns to the original state receives the reaction force from the operation piece 6k. I do.

It should be noted that the present invention is not limited to the above embodiment of the present invention, and it is needless to say that various modifications can be made without departing from the spirit of the present invention.

[0073]

As is clear from the above description, according to the automatic egg breaking device according to the present invention, a plurality of egg receiving holes are provided at equal intervals in a circumferential direction on a rotating disk that rotates around a vertical axis.
An egg top holder that holds the upper side of the egg attached to the egg receiving hole is provided on the upper side of the turntable and cuts a part of the outer periphery of a predetermined portion of the egg that rotates around the vertical axis and protrudes from the lower part of the egg receiving hole By installing a rotating blade and inserting it into this notch and opening the lower side of the egg shell downward and breaking the egg shell, the shell opening claw is provided on the lower side of the turntable, so that large and small eggs can be inserted into the egg receiving hole. The lower part of the egg protrudes from the lower part of the egg receiving hole regardless of the size of the egg, and the diameter of the egg at the lower part of the egg receiving hole is almost the same regardless of the size of the egg. It is possible to cut a part of the outer periphery of the lower part of the egg and make a cut in the same state without the need for a sensor to detect the size and without fine adjustment of the rotating blade according to the size of the egg . Then, the egg can be reliably broken regardless of the size of the egg simply by inserting the shell opening claw into the cut and opening the lower side of the egg shell downward. Furthermore, unlike conventional cutting of the whole circumference of the egg, the cutting amount for cutting is, for example, about one third of the whole circumference. It is possible to reduce the amount by a factor of about 1, and it is possible to minimize the mixing of a part of the cutting powder into the contents of the egg. In addition, in the case of holding eggs from both sides with a conventional suction device, eggs that were partially broken could not be broken because the contents were sucked out of the broken portion by the suction device and jumped out. However, the device of the present invention is different from the structure held by the suction device,
This is an extremely novel and beneficial effect, such as the ability to reliably break even partially broken eggs.

When an interlocking mechanism is provided for rotating the shell opening claw by a predetermined angle in conjunction with the turntable, the egg mounted in the egg receiving hole is rotated. The lower part of the shell of the egg can be broken by the claws between the shells.
