Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a food molding machine that uses a machine to mold food products such as nigiri sushi that were previously molded by hand.

[Prior art]

2. Description of the Related Art Food molding machines are known that automatically mold foods such as nigiri sushi, which were conventionally molded by hand. This item is a special public service issued in 1988.
As disclosed in Japanese Patent No. 3660, the rice fed into the chute is connected to the chute, and
The food is pushed out from the chute side through a food passage whose tip end is constricted by a drive mechanism, and the food pushed out from this food passage is conveyed by a belt conveyor and automatically formed into sushi-shaped, rice ball-shaped, etc. by a forming mechanism at a predetermined location. It is something to do.

[Problem that the invention seeks to solve]

However, in the conventional food molding machine,
The problem was that the mechanism was complex, large, and expensive.

An object of the present invention is to provide a convenient food molding machine that solves the above-mentioned problems of conventional machines and can easily mold foods such as nigiri sushi even at home. .

[Means for solving problems]

In order to achieve the object, the present invention has the following configuration. That is, the housing;
A food molding member provided within the housing;
a drive mechanism connected to the food molding member and driving the food molding member; and a drive mechanism located above the food molding member in the housing and movable to the food molding member side and the opposite side thereof. A food thrower with a food forming member side and an open upper part, and a food forming member of the food thrower that is provided on the inner surface of the food thrower and holds the food supplied inside the food thrower. A protrusion for transferring the food to the food molding member by moving to the side and charging the food into the food molding member, and a housing wall and a wall on the opposite side of the food thrower from the food molding member. and a spring biasing the food dispenser in a direction opposite to the food molding member.

[Effect]

When the food thrower is moved to the food forming member side and the food thrower is in a free state, a spring provided between the wall of the food thrower on the side opposite to the food forming member side and the housing wall is activated. The force causes the food thrower to return quickly, and the protrusions on the inner surface of the food thrower hold the food inside the food thrower and transfer it to the food forming member, thereby throwing the food into the food forming member.

On the other hand, in the housing 5, a shaft 67 is rotatably provided above the worm 65 via a bearing 66 attached to the bottom plate 57. A worm wheel 68 is fixedly attached to this shaft 67, and this worm wheel 68 is meshed with the worm 65. In addition, two levers 69 are mounted on the shaft 67 with a worm wheel 68 in between.
is fixedly attached. This lever 69
is configured to rotate around a shaft 67 through a hole 70 formed in the bottom plate 57 and a hole 71 formed in the inner wall 8b. The tip of the lever 69 engages with the lower part of the outer surface of the rear wall 55a of the food dispenser 55 to push the food dispenser 55 in the direction of arrow D shown in FIG. Then, it is separated from the food dispenser 55.

Next, the operation of the food molding machine configured as described above will be explained.

First, the food dispenser 55 is filled with cooked rice for forming, and when the handle 42 is turned in a predetermined direction, the rotating shaft 41, the worm 43, the worm wheel 39,
The rotation transmission plates 32 and 33 rotate via the horizontal shaft 22, and the rotation transmission plates 36 and 37 rotate with the spring 30.
The rotation transmission plates 32 and 33 are circumscribed and rotated by the urging force of the rotation transmission plates 32 and 33.

At the same time, the rotor 20 and stepped pulley 31 rotate. When the stepped pulley 31 rotates,
Belt 49, small pulley 48, gears 53, 44, 4
5, rollers 14 and 15 rotate in the directions of arrows A and B shown in FIG. 1, respectively. Also at this time,
The large pulley 4 rotates via the belt 50, and the lever 69 rotates in the direction of arrow E in FIG. 3 via the worm 65, worm wheel 68, and shaft 67.

Therefore, in the state shown in FIG. 4 in which the recess 25 of the rotor 19 and the recess 27 of the rotor 20 are separated on the rollers 14 and 15 side, the rear wall 55a of the food dispenser 55 is pushed by the lever 69, and as shown in FIG. Move in the direction of arrow D and touch the front wall 59a of the box 58.
When the lever 69 approaches the food dispenser 55 and reaches the position shown by the two-dot chain line in FIG.
distance from. Then, the food dispenser 55 is moved by the spring 6
4 and moves in the direction of arrow C shown in FIG. This thrown out rice falls from the food supply hole 60 and falls to the rollers 14 and 15.
and is forcibly sent downward by teeth 18,
It is supplied into the spaced apart recesses 25, 27. It should be noted that when the food dispenser 55 moves in the direction of arrow D in FIG. Furthermore, when the food dispenser 55 moves in the direction of arrow C in FIG.
Since the shape of the pleats 63 is serrated as shown in the figure, and the tips thereof are directed toward the food forming member side, the pleats 63 do not become an obstacle to the ejection of rice toward the food supply hole 60 side. . As the handle 42 continues to be turned, the concave portions 25 and 27 rotate in the direction in which they are opposed to each other, and as the concave portions 25 and 27 become opposed to each other, the rice is compressed, and the concave portions 25 and 27 are placed in the fifth position. When facing each other as shown in the figure, the rice is most compressed and formed into a sushi shape. When the handle 42 is further turned, the recess 2
5 and 27 are separated from each other on the turntable 52 side, and from between these recesses 25 and 27, sushi rice formed into a sushi shape is sequentially discharged onto the rotating turntable 52 so as to be lined up in the circumferential direction. .
When this operation is repeated with a plate placed on the turntable 52, the sushi rice balls are arranged on the plate.

According to this embodiment, since it does not require power such as a motor and has a simple structure, it can be downsized, and food such as sushi and rice balls can be easily formed at home and automatically placed on a plate. can be arranged in In addition, since the box 58, food dispenser 55, front lid 6, and guide body 11 can be easily attached and detached, cleaning before and after use is easy and sanitary.

In addition, in the embodiment, the rotors 19, 2
Although 0 is a pentagonal cylinder, the present invention is not limited to this, and other polygonal shapes may be used as long as the rotor and the rotation transmission plate have similar end surfaces.

Further, in the embodiment, the rotors 19, 2
The shape of the recesses 25 and 27 formed at 0 was made into a shape for forming nigiri sushi or rice ball,
The shape is not limited to this, and may be any desired shape for molding food.

Further, in the embodiment, the teeth 18 of the roller
was set in the direction shown in Fig. 1, and the rice before forming was strongly conveyed downward. However, the present invention is not limited to this, and the conveyance force of the rice can be increased by reversing the rollers or exchanging the left and right sides to change the orientation of the teeth 18. It is also possible to adjust the conveyance state of the rice by changing the distance between the rollers 14 and 15 as appropriate, or by eccentrically rotating the rollers 14 and 15. Further, instead of the teeth 18 of the roller, protrusions of other shapes may be provided to convey the unformed food product downward.

Further, in the first embodiment, the worm wheel 68 and the lever 69 were attached to the bottom plate 57 of the box 58 via the bearing 66 and the shaft 67, but the present invention is not limited to this, and the front wall 7, the middle wall 8a, 8b, an upper plate is provided at the upper end of the rear wall 9, and a bearing 66 and a shaft 6 are mounted on this upper plate.
A worm wheel 68 and a lever 69 may be attached via 7.
