[0010]
FIG. 5 is a schematic diagram showing the overall configuration of the shaping mechanism (6), and FIG. 6 is a schematic diagram for explaining the opening / closing mechanism (65).
The shaping mechanism (6) is disposed at substantially the same height as two upper rollers (61), (61), and disposed at an intermediate position and below the two upper rollers (61), (61). One lower roller (62), a wire conveyor (63) stretched around the outer circumference of these three rollers, and an intermediate position between the two upper rollers (61) and (61) and the wire conveyor (63). 63), and a weight roller (64) mounted on the upper part of (63), and an opening / closing mechanism (65) for moving the two upper rollers toward and away from each other.
[0011]
The two upper rollers (61) are connected to the rotating shafts (67a) and (67b) by connecting rods (66), respectively.
Although not shown, both ends of the lower roller (62) and the two rotating shafts (67a) and (67b) are rotatably fixed to an inverted triangular plate so that the positional relationship does not change. Have been.

[0012]
Hereinafter, the operation of the opening / closing mechanism (65) having the above configuration will be described.
First, in the normal state, the operating rod (69) is urged upward by the spring (6a). In this state, the two upper rollers (61) and (61) are separated from each other as shown in FIG. In state.
When the operator steps on the foot pedal (6b) with his / her foot or presses down the operation rod (69) with his / her hand, one of the rotation shafts (67a) connected to the operation rod (69) rotates counterclockwise, Accordingly, the gear (68a) also rotates counterclockwise.
Then, the gear (68b) meshing with the gear (68a) rotates clockwise, and accordingly, the other rotating shaft (67b) rotates clockwise.

[0015]
Hereinafter, a method of manufacturing a sushi roll using the sushi roll manufacturing apparatus having the above configuration will be described.
First, sushi rice is put into the hopper (1), and is transported on the first conveyor (2) while being loosened by the stirring blades (8).
The sushi rice transported by the first conveyor (2) falls between the two rollers (31) and (31) constituting the drop supplying means (3), and the two sushi rice rotating inward each other. It falls onto the second conveyor (4) from the gap between the rollers (31) and (31).
The rotation cycle of the rollers (31) and (31) is set such that when the sushi rice falls, the concave portions (3b) face each other and face diagonally upward, whereby the sushi rice is rolled ( The rice is not crushed because it enters the concave portion (3b) formed on the surface of the roller (31), and a plurality of annular concave grooves (3a) formed on the surface of the roller (31) allow the rice other than the concave portion (3b). Part of the sushi rice does not collapse.
[0016]
The sushi rice dropped downward from the drop supplying means (3) is conveyed by the second conveyor (4), and the surface is leveled by the leveling means (7).
At this time, the roller constituting the leveling means (7) is formed with a plurality of concave portions (71) and a plurality of concave grooves (72), so that the sushi rice is not crushed by the rollers.
[0017]
The sushi rice continuously conveyed by the second conveyor (4) is cut to a fixed length by the cutting mechanism (5) by intermittent vertical drive of the cutting blade (53) with the rotation of the rotating cam (51). In this state, it is supplied to the shaping mechanism (6) in the next step.
The flow of the sushi rice so far is indicated by an arrow in FIG.
[0018]
In the shaping mechanism (6), a certain amount of sushi rice flowing from the previous process is prepared in the form of a rolled sushi, but in the rolled sushi making apparatus according to the present invention, both normal rolled sushi and California rolls are produced. First, the case of making normal rolled sushi will be described.
[0019]
When making a normal rolled sushi, in the state where the sushi rice (S) cut to a certain length is conveyed on the wire conveyor (63), the ingredients (G) are put on the sushi rice (S). Is placed (see FIG. 9).
Next, when the operator steps on the foot pedal (6b) with his / her foot or presses down the operating rod (69) with his / her hand, the two upper rollers (61) and (61) approach each other, and the weight rollers (FIG. (Not shown), the wire conveyor (63) stretched between the two upper rollers (61), (61) descends, and the ingredients (G) begin to be caught by the sushi rice (S) ( (See FIG. 10).
Then, immediately before the ingredients (G) are caught in the sushi rice (S), the laver (N) is inserted along the wire conveyor (63) (see FIG. 11).
Then, the ingredients (G) are completely wrapped around the sushi rice (S), and the seaweed (N) is wrapped around the sushi rice (S). (See FIG. 12).
The finished rolled sushi is released between the two upper rollers (61) and (61) by releasing the foot pressing the foot pedal (6b) or the hand pressing the operating rod (69). The raised wire conveyor (63) can be easily taken out by raising it again.
[0020]
In the case of making a California roll, in a state where the sushi rice (S) cut to a certain length is transported on the wire conveyor (63), the seaweed (N) and the ingredients are put on the sushi rice (S). (G) is placed (see FIG. 13).
Next, when the operator steps on the foot pedal (6b) with his / her foot or depresses the operating rod (69) with his / her hand, the operation is carried out between the two upper rollers (61) and (61) by the above operation. The wire conveyor (63) descends, and the ingredients (G) and the nori (N) are caught by the sushi rice (S) (see FIG. 14), and finally the nori (N) is contained in the sushi rice (S). A so-called California-style sushi roll with the ingredients (G) involved is completed (see FIG. 15).
[0021]
In the case where the sushi is not sufficiently tightened by the above operation alone, the sushi is pressed obliquely from the outside of the wire conveyor (63) by the pressing mechanism (9) in the state of FIG. 12 or FIG. Thereby, a rolled sushi that is tightly wound can be obtained.
[0022]
