2. Description of the Related Art Sushi packaging, for example, seaweed hand-rolled sushi,
Nori seaweed is enclosed in a moisture-proof film bag, so-called nori seaweed packaging film, which is made portable by wrapping sushi wrapped around plate-like cooked rice in the core. Is taken out from the bag portion of the packaging film, and the sushi wrapped in the film is wrapped with the taken-out seaweed to be eaten as seaweed hand-rolled sushi. Such seaweed hand-rolled sushi is made by forming cooked rice into strips, cutting the strip-shaped cooked rice produced in this way into a specified length, producing plate-shaped cooked rice, and placing ingredients on the plate-shaped cooked rice. The plate-shaped cooked rice on which this ingredient is placed is rolled with the ingredient as a core to produce rolled sushi, and the rolled sushi produced in this manner is wrapped with a packaging film containing nori.

Strip-shaped cooked rice for seaweed hand-rolled sushi is produced by a strip-shaped cooked rice producing apparatus. The band-shaped cooked rice manufacturing apparatus includes a plurality of pairs of molding rollers, and a molding space for molding the band-shaped cooked rice is formed between each pair of molding rollers so that the cooked rice is molded therethrough. The plurality of pairs of forming rollers are formed by gradually narrowing the gap between the forming rollers in each pair so that the thickness of the strip-shaped cooked rice formed therein is gradually reduced as the cooked rice is moved from top to bottom. It is arranged in columns. Therefore, in this strip-shaped cooked rice manufacturing apparatus, the cooked rice is pressed from both sides between the pair of molding rollers while moving from the upper side to the lower side by the molding action of the plural pairs of molding rollers arranged in plural stages. Then, the adhesiveness of the rice grains is formed into a band shape.

[0004]

SUMMARY OF THE INVENTION In a strip-shaped cooked rice producing apparatus, cooked rice is continuously and sequentially formed into a strip shape between each pair of forming rollers, and discharged from the lowermost forming rollers to a conveyor belt below. . However, the strip-shaped cooked rice is relatively easy to fold when placed on the conveyor belt, and once the strip-shaped cooked rice is broken, it becomes a broken state and it becomes impossible to maintain the strip-shaped cooked rice. This is a problem because it hinders the work of the rolling process. An object of the present invention is to eliminate problems such as breakage of strip-shaped cooked rice when it is extruded from the strip-shaped cooked rice production apparatus and placed on a conveyor belt.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a strip-shaped cooked rice production apparatus which allows a strip-shaped cooked rice extruded from the strip-shaped cooked rice production apparatus to be placed on a conveyor belt without breaking. That is, the present invention provides a conveyor belt, a pair of guide walls disposed on the conveyor belt at intervals in the width direction of the conveyor belt and extending in the traveling direction of the conveyor belt, and the guide walls. A cooked rice supply port formed between the walls, and a pair of first forming rollers arranged below the cooked rice supply port in parallel with a first gap in the traveling direction of the conveyor belt, A first cooked rice molding region formed between the molding rollers,
Below the first forming roller, a pair of second forming rollers arranged in parallel at a second interval narrower than the first interval, and below the first cooked rice forming region, A continuous cooked band rice cooker comprising a second cooked rice forming region formed between second mold rollers, characterized in that a feed member for the cooked band is provided below the second mold rollers. It is in a continuous production device for banded cooked rice.

In the present invention, the cooked rice is formed into a strip shape by a continuous strip-shaped cooked rice producing apparatus and is continuously supplied to the conveyor belt in a strip shape. In the present invention, in the continuous production device for banded cooked rice, in order to regulate the width of the band of cooked rice to be formed, two guide walls are arranged in parallel with each other at intervals along the traveling direction of the conveyor belt. It is provided. In the continuous production device for banded rice, the banded rice forming area is
It is formed between two guide walls.

Also in the present invention, the strip-shaped cooked rice forming region is formed between a pair of left and right forming rollers, as in the conventional strip-shaped cooked rice continuous manufacturing apparatus. Generally, a plurality of pairs of forming rollers are vertically arranged in pairs. Are sequentially arranged. When forming a plurality of strip-shaped cooked rice forming regions in the vertical direction, a pair of left and right forming rollers are provided in the vertical direction between the guide walls,
The gap between the forming rollers in the immediately lower stage is smaller than the gap between the forming rollers in the upper stage. In this way, the gap between the forming rollers is gradually reduced and the passage through which the cooked rice passes is gradually tapered so that the grains of the cooked rice are pressed while moving downward and stick to each other. A stable and stable band of cooked rice can be formed. By forming a pair of left and right forming rollers in a plurality of stages between the uppermost forming roller and the lowermost forming roller, it is possible to increase the number of stages in the forming area. With the increase in the number of steps in the forming region, a stable cooked rice band, that is, a band-shaped cooked rice can be formed.

In the present invention, in order to continuously feed the strip-shaped cooked rice from the strip-shaped cooked rice continuous production device onto the conveyor belt without breaking, a feeding member is provided below the bottommost cooked rice forming region. To be In the present invention, the feed member may be a roller with a feed claw similar to the forming roller, but the roller with a feed claw is more suitable than the forming roller in order to gently drop the banded rice on the conveyor belt. The roller diameter can be reduced. Further, the feeding member can be formed of a conveyor belt so that it can be reliably placed on the conveyor belt.

When the feed member for the strip-shaped cooked rice is a roller similar to the forming roller, this feed roller is provided at a position that blocks the passage of the strip-shaped cooked rice extruded from the lowermost strip-shaped cooked rice forming area. It prevents the broken pieces from forming a strip of cooked rice on the conveyor belt. By providing the feed roller in this way, a stable band of cooked rice, that is, a strip of cooked rice can be formed on the conveyor belt, and the number of molding stages in the continuous cooked rice manufacturing apparatus can be reduced. Therefore, it is possible to prevent the band of the cooked rice from breaking.

In the present invention, the strip-shaped cooked rice extruded from the lowermost cooked rice forming region is guided by the feeding member,
It is placed on a conveyor belt and conveyed by the conveyor belt. Therefore, the strip-shaped cooked rice extruded from the bottommost cooked rice forming area is pulled by the cooked rice placed on the conveyor belt and is gently curved by the feeding member,
It will be placed gently on the conveyor belt, preventing the rice band from breaking. In the present invention, as the forming roller and the feeding member, a roller having a claw over the entire length on the major axis side can be used.

[0011]

According to the present invention, since one feeding member is provided below the opening of the lowermost cooked rice forming area in the continuous strip-shaped cooked rice manufacturing apparatus provided on the conveyor belt, it is extruded from the lowermost cooked rice forming area. The band-shaped cooked rice is guided by the feeding member and gently bends to change its direction and is placed on the conveyor belt, so that the band-shaped cooked rice does not curve sharply and is not broken, and it is surely continuous. Band-shaped cooked rice can be produced and fed to a conveyor belt.

FIG. 1 is a schematic side view mainly showing a band-shaped cooked rice forming process in one embodiment of the present invention, and FIG. 2 is a schematic side view of another embodiment of the present invention.
It is an outline side view mainly showing a band-shaped cooked rice forming process. 1 and 2, the same reference numerals are used for common portions.

In FIG. 1, a strip-shaped cooked rice forming apparatus 1 is for continuously producing strip-shaped cooked rice for seaweed hand-rolled sushi, and is usually provided on a conveyor belt 3 which moves in the direction of arrow 2. The strip-shaped cooked rice forming apparatus 1 includes a pair of guide plates 4 (one of which is not shown) arranged in parallel along the traveling direction of the conveyor belt 2 and a vertical feed forming unit 5 and a strip-shaped cooked rice feed unit. 6 is provided.

The vertical feed forming section 5 is a hopper 7 for supplying cooked rice.
Of the upper stage forming roller 8 is provided below the upper stage forming roller 8 at a position protruding below the upper stage forming roller 8 from the space between the upper stage forming rollers 8. Is also provided with the lower-stage forming rollers 9 arranged on the left and right with a narrow interval. The pair of upper forming rollers 8 are driven by a drive source (not shown) such as a prime mover and a gear mechanism to rotate in the direction of arrow 10,
A first molding region 11 is formed between them. The pair of lower forming rollers 9 are driven by a drive source (not shown) such as a motor and a gear mechanism to rotate in the direction of arrow 12 and form a second forming region 13 therebetween. .

The band-shaped cooked rice feeding section 6 has a second molding region 13
A feed roller 14 is provided below the sheet. The feed roller 14 is driven by a drive source (not shown) such as a prime mover and a gear mechanism, rotates in the direction of an arrow 15, and is extruded from the second molding region 13 (not shown). 1) is moved to the right in FIG. 1 so that the strip-shaped cooked rice is placed on the moving conveyor belt 2 without breaking. In this example, the upper stage forming roller 8, the lower stage forming roller 9 and the feed roller 14 are each provided with a projection 16 for a feed claw in order to reliably feed the band-shaped cooked rice.

The thickness adjusting section (not shown) is formed on the front side of the belt-shaped cooked rice feeding section 6 in the moving direction of the conveyor belt 2 with a thickness adjusting roller (not shown). In the thickness adjusting roller, the size of the gap between the surfaces of the conveyor belt 2 and the thickness adjusting roller is adjusted to the thickness of the cooked rice band. In the thickness adjustment area of the conveyor belt 2,
Since the underlay reinforcing member 17 of the conveyor belt 2 is provided, the pressurization of the thickness adjusting roller can be performed without bending the conveyor belt 2, which is effective.

Since the apparatus of this example is formed as described above, the cooked rice supplied from the hopper 7 is first compressed in the first molding region 11 by the pair of upper molding rollers 8 to form rice grains. Are adhered to each other and are sent to the second molding region 13 having a narrower molding interval than the first molding region 11, and the cooked rice is further compressed so that the rice grains adhere to each other and are formed into a band shape. It is pushed out from between. The strip of cooked rice extruded from between the pair of lower forming rollers 9 is guided by the feed roller 14 and transferred onto the conveyor belt 2. In this example, the cooked rice band was not broken, and the cooked rice band was reliably sent to the next step by the conveyor belt.

When the conveyor belt 2 is moved, it is sent to the thickness adjusting section, and the thickness is adjusted by the thickness adjusting roller. The thickness-adjusted cooked rice strip is then sent to a cutting unit (not shown) equipped with a conventional cutting device for producing laver rolls, and cut into plate-shaped cooked rice of a predetermined length. The plate-shaped cooked rice cut in this manner is sent to a conventional cooked rice roll-making device for laver-rolling, where the ingredients are placed and wound with the ingredients as the core. To produce a rolled rice cooked with the ingredients as the core.

In the embodiment shown in FIG. 2, in addition to the feed roller,
This is an example in which an auxiliary feed roller having a diameter smaller than that of the feed roller is provided in front of the feed roller in the feed direction, and differs from the embodiment shown in FIG. 1 in that the auxiliary feed roller is provided,
Other points are the same as the embodiment shown in FIG. In the embodiment shown in FIG. 2, an auxiliary feed roller 18 having a smaller diameter than the feed roller 14 is provided in front of the feed roller 14 in the feed direction. The auxiliary feed roller 18 is driven by a drive source (not shown) to rotate in the direction of arrow 19. In this example, the auxiliary feed roller 18 is provided with the projection 20 for the feed claw, like the forming rollers 8 and 9 and the feed roller 14.

In the example of FIG. 2, since an auxiliary feed roller is provided, when the feed roller 14 is rotated in the direction of arrow 15 and the auxiliary feed roller 18 is rotated in the direction of arrow 19, the feed roller 14 is rotated. The fed cooked rice band is placed on the conveyor belt 3 from the height of the auxiliary feeding roller 18 by the feeding of the auxiliary feeding roller 18. By setting the diameter of the auxiliary feed roller 18 to be relatively small,
The height at which the cooked rice strip is placed on the conveyor belt 3 becomes small, and at the stage of placing it on the conveyor belt 3, it is possible to prevent the cooked rice strip from breaking.

In the above example, a roller with a claw similar to the forming roller is used as the feed roller, but a conveyor belt can be used instead of the roller. Also, by using multiple auxiliary feed rollers, the belt of rice cooked rice can be supplied to the conveyor belt by reducing the roller diameter so that the height at which the rice cooked rice is placed on the conveyor belt can be set to the conveyor belt surface as much as possible. The belt-shaped cooked rice can be smoothly transferred to the conveyor belt,
