In addition, in the position adjustment operation of the width direction position of the seaweed sheet N, the main control unit C is in a rotating state of the rotary motor 2b via the drive control circuit 13 for transporting the seaweed sheet so that the position adjustment can be performed well. (Rotation speed, etc.) may be adjusted.

Next, an example of a method for producing seaweed rolls of the continuous seaweed roll molding machine M1 will be described with reference to FIGS. 1, 2, 2, 5 and the like.

First, when the power of the continuous seaweed winding molding machine M1 shown in FIGS. 1 and 2 is turned on, the liquid crystal screen of the operation panel 6 is turned on and the menu screen is displayed, so that the operator can use the seaweed sheet through the operation panel 6. Width (thick roll, medium roll, thin roll, etc.), cut size of seaweed roll, speed, various modes, etc. are input.

Then, in the continuous seaweed winding molding machine M1, the bobbin drive is performed based on the information of the width (thick winding, middle winding, thin winding, etc.) of the seaweed sheet N input to the operation panel 6 under the control of the main control unit C. The drive device 7c (see FIG. 5 and the like) is driven, and the holding position of the roll-shaped seaweed sheet N of the bobbin 2a for supplying seaweed is automatically set to a position suitable for the width of the seaweed sheet N. Here, for example, the holding position of the seaweed sheet N is set so that the center position of the seaweed sheet N in the width direction coincides with the inlet position of the winding forming portion 4.

Further, the drive device 7b (see FIG. 5 and the like) for driving the position detection sensor is driven based on the width information of the seaweed sheet N input to the operation panel 6 under the control of the main control unit C, and the position detection sensor 7a is driven. The installation position (position in the direction of the arrow As) is automatically set to a position suitable for the width of the seaweed sheet N. Here, for example, the position of the position detection sensor 7a is set so that one end of the seaweed sheet N in the width direction can be detected.

Subsequently, when the operation start button on the display screen of the operation panel 6 is touched to start the operation of the continuous seaweed winding molding machine M1, the cooked rice supply unit 1, the seaweed supply unit 2, the conveyor 3, the winding forming unit 4 and the cutter are started. The unit 5 starts driving.

That is, in the seaweed supply unit 2, the bobbin 2a is rotated by the rotary motor 2b, and the roll-shaped seaweed sheet N wound around the bobbin 2a is supplied onto the measuring conveyor 3a. On the other hand, in the cooked rice supply section 1, the cooked warm cooked rice (vinegared rice) is carried by the rice lifter section 1a to the supply hopper section 1b above the continuous seaweed winding molding machine M1 and thrown into the cooked rice. The cooked rice charged into the supply hopper 1b is unraveled by the unraveling blades in the supply hopper 1b, then sent to the lower vertical measuring section 1c, and passes between the three-stage roller pairs in the vertical measuring section 1c. As a result, it is formed into a plate-shaped rice sheet and placed on the seaweed sheet N on the measuring conveyor 3a.

The laminate of the seaweed sheet N and the rice sushi sheet is sent from the weighing conveyor 3a to the topping conveyor 3b, and is manually placed on the rice sushi sheet by an operator, for example, various kinds of rice such as eggs, kamaboko, natto, and gourd. After the ingredients are placed, they are sent to the winding conveyor 3c.

The seaweed sheet N, the rice sushi sheet, and the laminate of the ingredients sent to the winding conveyor 3c are wound and formed by gradually winding the belt B3 of the winding conveyor 3c into a cylindrical shape on the winding conveyor 3c.

The position of one end of the seaweed sheet N at this time is set as the reference position x0. In this state, the bobbin 2a for supplying seaweed is not moved in the width direction of the seaweed sheet N.

Here, when the position detection sensor 7a is in a state of detecting the seaweed sheet N as shown in FIG. 8C while the seaweed sheet N is being conveyed, the seaweed sheet N is above FIG. 8C. The bobbin 2a for supplying seaweed is indicated by arrow Ab1 while the seaweed sheet N is being conveyed so that the position of one end of the seaweed sheet N returns to the reference position x0 in FIG. 8 (b). The seaweed sheet N is automatically moved in the width direction (below FIG. 8C).

On the other hand, when the position detection sensor 7a does not detect the seaweed sheet N as shown in FIG. 8D during the transportation of the seaweed sheet N, the seaweed sheet N is located below FIG. 8D. Since the position is misaligned, the bobbin 2a for supplying seaweed is indicated by arrow Ab2 while the seaweed sheet N is being conveyed so that the position of one end of the seaweed sheet N returns to the reference position x0 in FIG. 8 (b). The sheet N is automatically moved in the width direction (above FIG. 8D).

By doing so, in the continuous seaweed winding molding machine M1 of the present embodiment, the position of the seaweed sheet N in the width direction during transportation can be adjusted, so that the seaweed sheet N is conveyed without meandering. Can be done. Therefore, it is possible to prevent the occurrence of defective products due to the misalignment of the seaweed sheet N.
