57 is a seaweed case containing seaweed 62, which is made of acrylic or the like so that the inside can be seen through.

Making seaweed-wrapped sushi l using the seaweed-rolled sushi manufacturing apparatus having the above-described configuration is performed through the following steps.

(1) Preparation process In the state shown in FIGS. 1 and 6 in which the rice sushi rice supply frame 13 is set on the horizontal surface 2b of the sheet 2 of this device, spread the rice sushi rice 60 flat in the rice sushi supply frame 13, and place it in the center. A groove is made, and toppings 61 such as dried gourd, pickled incense, and tuna are put into the groove, and seaweed 62 is spread on the inclined surface 2a of the sheet 2 in front of the groove to complete the preparation process.

(2) Winding and winding process When the start switch 53 is pressed, the chain 19, chain conveyor 40, and belt conveyor 50 rotate in the direction shown by the arrow. When the chain 19 rotates, the gears shift from the second gear 25 meshing with the rack 24 to the intermediate two gear 27 and the gear 29.
The rotational force that has been decelerated is transmitted to the shaft 30. axis 30
When rotates, the winding arm 9 swings, the stopper 15 comes off, the rice sushi supply frame 13 is reversed upward by the spring force, and the guide roller 33 rises from the lower end depressed portion 32a of the guide groove 32. At this time, the gear connecting block 8 is also guided by the guide rail 35 and ascends. When the guide roller 33 moves to the straight part of the guide groove 32, the winding arm 9 rises while stopping its swinging. When the chain 19 further rises, the winding arm 9 as shown in FIG.
rotates, and along with this, the winding roll 4 pushes up the sheet 2 and rotates forward so as to wrap around the shari 60, so that the shari 60 is a cylindrical portion formed by the shari guide 16, 16 and the sheet 2. At the same time as the tool 61 is pushed in, the winding arm 9 moves forward, and the winding roll 4 advances along the type A1 surface 2a of the sheet 2 to the tip of the sheet 2. The seaweed 62 is rolled up into a cylindrical shape by the sheet 2. In this way, the ingredients 61 are
The seaweed-wrapped sushi l, which enters the center of the sheet 0 and has its outer periphery wrapped around the seaweed 62 to form a cylindrical shape, is placed in the sheet 2 as shown in FIGS. 3 and 8.
is transferred from the upper end to the receiving mold 45 of the chain conveyor 40.

(3) The seaweed-wrapped sushi 1 transferred from the pre-molding process to the mold 45 is pressed by the press mold 46 that follows the mold 45 as the chain conveyor 40 rotates, and changes from a cylindrical shape to a rounded shape as it descends on an incline. After being press-molded, the mold is opened by the pressing die 46 at the lowest point, and the nori-wrapped sushi l having rounded corners is transferred to the belt conveyor 50.

(4) Sending process The seaweed-wrapped sushi l that has been formed into a rounded shape and transferred to the belt conveyor 50 in the pre-processing process is conveyed to the front lower part of the apparatus by the belt conveyor 50, and then transferred to a packaging process or the like.

During the above process, the reciprocating motion in the winding process is caused by a limit switch issuing a reverse command to the drive motor (not shown) to descend. Further, the positional relationship between the seaweed-wrapped sushi l and the mold 45 from the rolling process to the forming process is set so that the sushi can be transferred smoothly under preset conditions.

After the above work is completed, the gear connecting plot 8 descends and the guide roller 33 moves into the lower end depressed portion 32 of the guide groove 32.
As it reaches point a, the winding arm 9 swings in the opposite direction and presses the stopper 15 against the tension of the spring as shown in FIG. 1, returning the sushi rice supply frame 13 to the state shown in FIG. set on the horizontal surface 2b of the sheet 2.

In this way, according to the present invention, all you have to do is place the rice sushi rice 60 and the ingredients 61 such as dried gourd, pickled vegetables, and tuna on the horizontal surface zb of the sheet 2, spread seaweed 62 on the inclined surface 2a of the sheet 2, and press the start switch 53. , The work of rolling up the seaweed sushi l can be performed automatically and continuously. In particular, in the present invention, the shari 60 etc. arranged on the horizontal surface 2b of the sheet 2 are once rolled up on the horizontal surface 2b by the sheet 2, and then further rolled up on the inclined surface 2a.
1 to wind up the sheet 2 along the
Because of this, the cylindrical seaweed-wrapped sushi l can be formed smoothly and reliably, and the seaweed 62 can tightly adhere around the sushi rice 60. In addition, the seaweed-wrapped sushi l rolled up into a cylindrical shape is automatically formed into rounded corners in the next process, so it looks good and is convenient for packaging, etc. Moreover, it is also convenient to pack it into boxes. Since the well-pressed seaweed-wrapped sushi 1' is delivered to the front, even one person can manufacture the seaweed-wrapped sushi 1 in an easy-to-follow manner.In addition, it is extremely hygienic because it can be manufactured without being touched during the forming process. It has many advantages such as:
