DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a boiled egg shelling device.

<Prior Art> As a conventional boiled egg shelling device, Japanese Patent Publication No. 25-25115.
As shown in Japanese Patent Publication No. JP-A-2003-264, the bottom of a cylindrical container having an inner peripheral wall with an uneven surface accommodates a rotating plate having an uneven line on the surface, and a large number of boiled eggs are accommodated inside the rotating plate. It is known that the eggshell is peeled off by rotating the.

<Problems to be solved by the invention> However, in the above-mentioned device, the eggshell is peeled off by accommodating and driving a large number of boiled eggs at the same time. However, there is a drawback that a rapidly peeled object collides with a delayed peeled egg, a peripheral wall, or the like to damage the peripheral surface, or the yolk inside projects and is damaged.

In addition, in the above device, because it is a badge system that shells a fixed amount of eggs together for a certain period of time, it is necessary for the operator to start and stop the device at all times and to supply and remove eggs. Since it has to be stopped and continuous operation is not possible, there is a drawback that it is uneconomical in terms of labor cost and work efficiency.

<Means for Solving the Problems> The present invention intends to provide an apparatus for solving the above-mentioned problems. First, a cylinder having a discharge window 6 for discharging eggs at a part of a lower end of a peripheral wall. -Shaped casing 7 is fixedly provided, and a rotating plate 8 forming an unevenness 8a on the upper surface and forming the bottom portion of the casing 7 is provided so as to be rotationally driven at a relatively high speed, and is inserted into the casing 7 so that the casing 7 In a structure having a partition 14 that divides the inside into a plurality of partitions 7a, a rotor 13 that rotates relatively slowly with the rotation of the rotating plate, and a nozzle 34 that injects cleaning water into the casing 7. At the outer peripheral position of the discharge window 6 of the casing 7, a water tank-shaped stocker 3 for storing water is provided, and a basket 24 for storing eggs 22 after shelling is removably accommodated in the stocker 3. , The second feature And,

A shower nozzle 34 is provided for sprinkling water on the eggs to be conveyed and removing the attached shells.

<Operation> The rotating plate 8 rotating at a relatively high speed causes the boiled eggs 22 placed on the upper surface thereof to contact the unevenness 8a on the surface to sequentially peel off the shells of the eggs, and the casing 7 is boiled eggs being shelled. The partition 22 of the rotor 13 forms a partition 7a so that the eggs on the rotating plate 8 do not mix with other eggs, and this is a slow rotation. By doing so, the peeling of the shell is controlled so that the peeling of the shell proceeds in the order in which the eggs are put in each compartment 7a, and the action of the centrifugal force exerted by the rotating plate 8 on the discharge window 6 completes the peeling of the eggs 22. It can be released to the next step.

Then, the released eggs 22 are in the basket in the stocker 3.
It was housed in 24 and the shell adhered by the water inside was dropped,
Eggs are taken out by taking out the basket 24.
In another example, the eggs 22 carried by the conveyor 33 or 38 are sprinkled with a sprinkling nozzle 34, and the attached shell pieces are washed and removed.

<Embodiment> The embodiment of the present invention shown below will be described in detail. FIGS. 1 to 3 show a first embodiment of the present invention. A shallow box-shaped stainless steel pallet 2 is fixedly installed.
A stocker 3 having an inverted trapezoidal shape and having a deep bottom is continuously formed between the end of the frame 1 and the front end of the frame 1.

On the bottom plate 4 in the pallet 2, a stainless steel casing 7 having a C-shaped cross section and having a discharge window 6 having a cutout is formed on the front side. At the bottom of the casing 7, a rotating disk 8 made of zinc alloy or the like having a large number of radial convex shapes 8a formed on the upper surface is rotatably supported, and the rotating disk 8 is below the pallet 2. The drive device such as the motor 9 attached to the

Further, a left and right gate frame 11 is horizontally provided in the upper center of the casing 7, and a rotor 13 having a shaft 12 concentric with the rotating disk 8 is pivotally supported on the gate frame 11, A plurality of vane-shaped partitions 14 made of stainless steel are fixed around the shaft 12 in a tangential and radial manner, and are supported by being inserted into the casing 7 from above. The partition 14 is in a state of dividing the casing 7 into a plurality of partitions 7a.

A pulley 16 is attached to the upper end of the shaft 12 of the rotor 13, and a belt 19 is wound around a drive pulley 18 of a motor 17 provided at the rear of the frame 1, and the rotor 13 is a rotating disc. It is rotationally driven in the same direction (clockwise direction) as 8 at a relatively slow speed (for example, 7.5 to 10 rpm).

21 is a motor cover for accommodating the motor 17 and frame 1
The discharge window 6 of the casing 7 is provided at the rear end of the casing 7.
An egg feeding device 23 such as a chute that sequentially supplies the boiled eggs 22 to each of the compartments 7a that move with the rotation of the rotor 13 is opened on the left side of the rotor 13. In the illustrated example, the rotor 13 makes one round. The mechanism is such that a total of 6 boiled eggs 22 are supplied, one for each section in between.

In the above structure, the pallet 2 and the stocker 3 are
The boiled egg 22 that contains water to the extent that the water surface sufficiently covers the upper surface of the rotating disk 8 and is sequentially supplied to each compartment 7a is
While the rotor 13 is rotated in the clockwise direction in sequence, the rotating disk 8 is rotated and the egg shell is peeled off. Then, the boiled eggs 22 are circled around by the rotor 13 and a total of 6 boiled eggs are discharged from the discharge port 6 into the water in the stocker 3 in the staircase where shelling is performed.

In the stocker 3, as shown in FIG.
The basket 24 having a coarse mesh fitted in the upper part of the container is stored, and the eggshell fragments are settled on the bottom of the stocker 3 and boiled eggs.
22 is left in the basket 24. When the basket 24 is housed in the stocker 3, a space 3a is formed at the bottom of the stocker 3 for storing shell fragments and the like. The basket 24 is replaced with an empty basket on the stairs in which a predetermined amount of peeled eggs are stored.

When the above device is used, the water is contained inside for the purpose of impact mitigation against eggs, protection of the egg white surface after shell peeling, separation and removal of attached egg shell fragments, and the like.

FIG. 4 shows a second embodiment of the present invention, in which the casing 7 is attached to the gate-shaped frame 11 with a bracket 27.
And a small gap between the lower end of the casing 7 and the outer circumference of the rotating disk 8 to release the peeled eggshell pieces.
28 are formed. A motor casing 29 for accommodating the motor 9 and supporting the rotating disc 8 is projectingly provided in the pallet 2 below the rotating disc 8. Further, an egg shell is provided around the rotor shaft 12 on the casing 7. A nozzle that sprays water into the casing 7 in a shower shape during peeling work
31 is the installed mechanism.

Then, when the shelled boiled eggs 22 are discharged from the discharge window 6, a chute plate 32 that guides the shelled eggs to the outside, a belt combiner 33 that receives the eggs that have been transferred from the chute plate 32 and conveys them to the next step, and the belt A shower nozzle 34 for washing off shell debris attached to the eggs on the conveyor 33, a brush 36 for removing the attached egg shells below the belt conveyor 33, and a belt conveyor 33
A shooter 37 for receiving eggs from the eggs and carrying them to another position is provided, and the shell pieces peeled and separated from the eggs are discharged or dropped from the gap positions indicated by arrows a ₁ , a ₂ , and a ₃ , respectively. .

FIG. 5 also shows the third embodiment of the present invention. The boiled egg 22 discharged from the casing 7 through the chute plate 32 is one of two parallel rollers provided below the chute plate 32. The book has a structure in which it is dropped onto a spiral conveyor 38 having a spiral strip 38a attached thereto and is conveyed to another. At this stage, the shell pieces attached to the boiled egg 22 are washed away by the water supplied from the upper shower nozzle 34 and fall downward from the gap between the two rollers.

In the present invention, in addition to the above-mentioned embodiments, the egg discharge window 6 of the casing 7 is formed by cutting out a part of the lower end of the peripheral wall of the casing 7, and the ridge 8a is formed on the surface of the rotating disk 8. Instead, forming a large number of projections on the spherical surface or adhering a large number of rubber or resin uneven rubbers, forming a large number of holes on the surface of the rotating disk 8, the rotor 13 and the rotating disk. It is possible to carry out many modified examples such as rotation of 8 by a single motor via a transmission or the like.

Further, as shown in the embodiment, it is preferable to rotate the rotor 8 in the same direction with respect to the rotation direction of the rotating disk 8 in terms of preventing damage to the eggs, etc. However, depending on the rotation speed adjustment of both, they rotate in opposite directions. It is also possible to cause a relative rotation difference.

<Effects of the Invention> According to the present invention configured as described above, eggs are sequentially stored in a compartment formed by a rotor that rotates at a constant speed and slowly, and shelling is performed for a fixed time. When there are differences in the size of eggs, the thickness and hardness of the shell, etc. as a result of the eggs not colliding with each other and the load of other eggs not being applied as compared to the case where a large number of eggs are thrown at the same time and the discs are rotated. However, it has the advantage that all eggs are uniformly and reliably shelled without damage.

Also, if eggs are sequentially supplied to each compartment according to the rotation speed of the rotor, shelling will proceed correspondingly, so automation of shelling work and continuous operation will be possible, and for loading and unloading eggs. It saves labor compared to the conventional one, which always requires human labor, improves work efficiency by continuous operation, and enables a large amount of shelling in a fixed time. For example, in a conventional device having a casing and a rotating plate of the same size,
In contrast to the processing amount of 1500 pieces / H, the present invention enables processing of 3000 to 4000 pieces / H.

Since the above-mentioned device has a basic structure including a rotating plate, a casing, and a rotor, the mechanism is simple, operation and maintenance are easy, and there are few failures and the machine itself is very inexpensive.

Furthermore, eggs can be stored in water in a stocker and a basket, and eggs without shells can be obtained without any special treatment. Similarly, there is an advantage that eggs without shells can be obtained even when water is sprayed by a nozzle while being conveyed by a conveyor.
