Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a forming machine for food products such as sushi.

[Prior art]

Conventionally, rice fed into a chute is pushed out by a drive mechanism through a food passage connected to the chute and narrowed at the tip end from the chute side, and the food delivered from this food passage is conveyed by a belt conveyor and molded at a predetermined location. Automatic food forming machines are known that use a mechanism to form food into sushi or rice ball shapes.

However, in such food forming machines,
The problem was that the mechanism was complex, large, and expensive.

[Problem that the invention seeks to solve]

The problem to be solved by the present invention is that it has a simple structure, can be miniaturized, is low in cost, and can be easily molded into foods such as sushi and rice balls at home.

[Means for solving problems]

Two parallel axes are attached to the center of a pair of polygonal prisms with concave portions formed on the outer periphery of the rotor, and two parallel axes are provided in the housing so that they can rotate and move closer to each other. a spring that is always biased in a direction to approach the rotor; a pair of polygonal plates having a similar shape to the rotor, the outer circumferences of which are opposite to each other and whose centers are fixed to the two parallel axes; and the pair of polygonal plates. Until the apex portions of the pair of polygonal plates face each other during rotation, the distance between the two parallel axes is allowed to be shortened, and when the apex portions of the pair of polygonal plates face each other, the two parallel axes A concave fitting portion provided at one apex corner of the pair of polygonal plates that fit into each other with a wider distance between them; and a convex fitting portion provided at the other apex corner of the pair of polygonal plates. and a manual rotation drive mechanism connected to the one polygonal plate.

[Operation] When the manual rotation drive mechanism is activated to rotate one polygonal plate, the other polygonal plate is circumscribed by the force of the spring, so this other polygonal plate is rotated. rotates, narrowing the distance between the two parallel axes until the apex portions of the pair of polygonal plates face each other, and widening the distance between the two parallel axes when the apex portions of the pair of polygonal plates face each other. As a result, when a plurality of paired rotors are rotated and food is supplied by the food supply means between two adjacent concave portions with an increased mutual interval, the food is delivered while one rotor rotates toward the other rotor. As they approach each other, the two concave portions of the plurality of rotors are compressed and molded into the desired molded shape as they approach the opposed state, and as one rotor rotates away from the other rotor, the two concave portions move away from each other. It is discharged outward from between these two recesses.

〔Effect of the invention〕

According to the present invention, by rotating one of a pair of polygonal plates, the rotation can be transmitted to the other polygonal plate and the distance between two parallel axes can be made closer to each other, thereby rotating the pair of rotors. When the concave portions of one rotor and the concave portions of the other rotor are separated, food is supplied between the two concave portions, and when these two concave portions face each other, the food between the two concave portions is compressed. When separated, the food can be discharged from between these two concave portions, so the structure is simple, the size can be reduced, the cost is low, and foods such as sushi and rice balls can be easily formed at home. Can be done.

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

First, place the container 5 on the housing 8 and the mounting plate 49.
Put 0. At this time, the exit 51 is connected to the belt 16,
It is located above between the guide plates 17.

Next, when the handle 36 is turned, the rotation shaft 34 is rotated, and the rotation transmission plates 26 and 27 are rotated via the worm 35, the worm wheel 32, and the horizontal shaft 21.
Along with this, the rotation transmission plates 30 and 31 rotate.

The gear 37 rotates via the small pulley 41 and the gear 47, and the gears 48, 38 also rotate, which causes the rollers 10, 11 to rotate, the roller 14 to rotate via the belt 16, and the large roller to rotate via the belt 43. Pulley 3 also rotates.

Therefore, in the state shown in FIG. 4 in which the recess 22 of the rotor 18 and the recess 22 of the rotor 19 are spaced apart on the rollers 10 and 11 side, cooked rice is put into the container 50 and the rice is passed from the outlet 51 to the housing 8.
It is dropped between the belt 16 and the guide plate 17 inside.
When the handle 36 is further turned, the rotation of the roller 11 and the belt 16 causes the rice to be transferred to the rotor 1.
8 and the recess 22 of the rotor 19, and is compressed as these recesses 22, 22 face each other as shown in FIG. It is then formed into a sushi shape. If you turn the handle 36 further,
The recesses 22, 22 are separated from each other on the turntable 46 side, and the compression-molded sushi rice is discharged from between these recesses 22, 22 onto the rotating turntable. When this operation is repeated with the plate placed on the turntable 46, the compression-molded sushi rice is sequentially arranged on the plate in the circumferential direction of the plate.

According to this embodiment, since no power such as a motor is required and the structure is simple, it can be downsized, and foods such as sushi and rice balls can be easily formed at home.

In addition, in the embodiment, the rotors 18, 1
The roller 1 feeds rice between the recesses 22 and 22 of 9.
This is carried out by the cooperative action of a conveyor formed by winding a belt 16 around the belts 0 and 14 and the roller 11 below the guide plate 17; however, the present invention is not limited to this; A conveyor consisting of another roller 10, 14 and a belt 16 may be used, or only the roller 11 may be used, or only the rollers 10, 11 may be used without the roller 14, belt 16, and guide plate 17.

Further, in the embodiment, the rotors 18, 1
The drive mechanism for these rotors 18 and 19 is composed of a rotating shaft 34, a worm 35, a worm wheel 32, approximately pentagonal rotation transmission plates 26, 27, 30, 31, a spring 24, etc. However, without being limited to this, if the outlines of the rotors 18 and 19 and the outlines of the rotation transmission plates 26, 27, 30, and 31 are the same shape (similar shapes), these rotors,
The rotation transmission plate may have another polygonal shape.

Further, in the embodiment, the rotors 18, 19
Although the shape of the recessed portion 22 formed in the sushi is made into a shape for forming sushi, the shape is not limited to this, and when making rice balls, the shape may be a shape that matches the shape of the food to be manufactured, such as a rice ball shape. Good too.

Further, in the above embodiment, the rotor 19 is fixed in position and the rotor 18 is moved close to and separated from the rotor 19. However, the present invention is not limited to this. The rotor 19 may be arranged close to and separated from each other, or the rotors 18 and 19 may be arranged near to each other and separated from each other.
