As shown in FIGS. 6D and 8, the machine frame right side wall forming body 23 of the sushi roll forming unit 3 includes a first sensor 96 that detects the origin (initial) position of the throttle forming body 31, and a diaphragm. A second sensor 97 for detecting the advance limit position of the part forming body 31 and a third sensor 98 for detecting the origin (initial) position of the plate-like sushi rice support / guide body 30 are provided. As the first to third sensors 96, 97, and 98, proximity sensors (inductive proximity switches) can be used.

  A controller 99 containing a CPU (Central Processing Unit) such as a microcomputer (microcomputer) is disposed at a predetermined position in the sushi roll manufacturing apparatus A. As shown in FIG. 12, on the input side of the controller 99, the operation / stop switch 6, the operation panel unit 8, the rolled sushi forming switch 9, and the first to third sensors 96, 97, 98 are provided. Connected. Further, the first and second driving electric motors M1 and M2 and the first and second actuating electric motors M3 and M4 are connected to the output side of the controller 99.

  Here, servomotors are used as the first and second driving electric motors M1 and M2, and these are connected to the controller 99 by RS485 serial signals and IO signals. Then, the controller 99 sends the rotation amount and rotation speed data to the first and second drive electric motors M1 and M2, which are servo motors, by serial communication. Each of the first and second driving electric motors M1 and M2 incorporates a sensor for detecting an output current. When a load is applied to each of the first and second driving electric motors M1 and M2, the output current increases. Therefore, the sensor detects the increased output current and outputs it to the controller 99 as load detection. When the output current exceeds the reference value for a certain time, the controller 99 determines that the belt body 28 is pulled in a tensioned state (substantially horizontal state). Then, the controller 99 sets the positions of the first and second drive rollers 25 and 27 when the belt body 28 is pulled in a tension state as the origin (initial) position, which is the start position of the subsequent operation cycle, for the sushi rice M The first and second drive rollers 25 and 27 are returned to their origin (initial) positions immediately before the operation is extended.

  The procedure for determining the origin (initial) position of the belt body 28 will be described with reference to FIGS.

(1) Origin (Initial) Positioning of Second Driving Roller 27 As shown in FIG. 13A, the belt body 28 is all wound up by the second driving roller 27. At this time, the first drive roller 25 is kept in a free state.
As shown in FIG. 13B, when all the belt body 28 is pulled out, the first drive roller 25 can no longer rotate, and the belt body 28 is in a tension state and becomes a substantially horizontal straight shape. At this time, a current equal to or higher than the reference value flows through the second drive electric motor M2 that drives the second drive roller 27, and the built-in sensor detects the load and outputs it to the controller 99. As a result, the controller 99 determines that all the belt bodies 28 have been wound, and stops the driving of the second drive electric motor M2.
As shown in FIG. 13C, in order to position the origin (initial) of the first drive roller 25, the second drive roller 27 is slightly rotated in the feeding direction (counterclockwise) to slightly move the belt body 28. This position is set as the origin position of the second drive roller 27 in a slack state.

(2) Origin (initial) positioning of the first drive roller 25 As shown in FIG. 13D, the first drive roller 25 is rotated in the winding direction (counterclockwise) to wind the belt body 28. take. At this time, the second driving roller 27 is kept stopped, and the belt body 28 in a slightly slack state shown in FIG.
As shown in FIG. 13E, when the belt body 28 is completely wound around the first drive roller 25, the belt body 28 becomes tensioned and becomes a substantially horizontal straight shape. At this time, a current equal to or higher than the reference value flows in the first drive electric motor M1 that drives the first drive roller 25, and the built-in sensor detects the load and outputs it to the controller 99. As a result, the controller 99 determines that all the belt bodies 28 have been wound, and stops the driving of the second drive electric motor M2. This position is set as the origin position of the first drive roller 25.

  Next, operation switches and the like will be described. When the operation / stop switch 6 is pressed during the stop, each drive unit is set at the operation start position and is set in a standby state. Further, when the operation / stop switch 6 is pressed during operation or standby of each drive unit, the operation or standby state is immediately released and the operation is stopped. The operation / stop switch 6 is provided with a lamp (not shown), and the lamp is turned on during operation and turned off during stoppage.

  The sushi roll forming switch 9 can start the plate-shaped sushi rice supply and start the sushi roll formation by pressing. A plate-shaped sushi rice supply start lamp (not shown) and a sushi roll formation start lamp (not shown) are provided in the vicinity of the rolled sushi formation switch 9, and the plate-shaped sushi rice supply start lamp blinks. When the sushi roll switch 9 is sometimes pressed, the supply of the plate-like sushi rice P is started. When the rolled sushi formation switch 9 is pressed while the rolled sushi formation start lamp is blinking, an operation of forming the plate-shaped sushi rice P into the spiral rolled sushi U is started.

Next, automatic control of each drive unit will be described.
The feed roll 12 of the sushi rice storage unit 1 receives an output signal from the first and second driving electric motors M1 and M2 for controlling the belt body 28, and the controller 99 receives the output of the feed roll 12. This is to output the drive output signal to the drive unit. The supply of the rice M is started, the controller 99 receives the stop output signal from the first and second drive electric motors M1 and M2, and the controller 99 feeds the roll. This is to stop the supply of rice M by outputting a stop output signal to the drive unit 12. Thereby, the supply roll 12 which supplies the sushi rice M, and the belt body 28 can be driven synchronizing. This is an effective use of the advanced positioning functions of the first and second drive electric motors M1 and M2, which are servo motors, and enables the supply of sushi rice M with much higher accuracy than timer operation. Yes. Therefore, the plate-shaped sushi rice P having a stable length can always be formed.

  A sensor (not shown) is provided at a non-cutting position where the cutter 15 is most retracted. When the plate-like sushi rice P is fed out, the cutter 15 is moved backward to this sensor position and the lower plate-like sushi rice forming rollers 14, 14 are moved. Set the opening directly below. When the cutter 15 closes the position immediately below the lower plate-shaped sushi rice forming rollers 14, 14, the cutter 15 is closed by a timer built in the controller 99.

  The belt body 28 is controlled by the first and second driving electric motors M1 and M2 which are servo motors. When the plate-like sushi rice P is transferred in the front-rear direction, the belt body 28 is slack, and the winding operation is performed. All the movements of the belt use the advanced positioning function of the servo motor. Therefore, the rolled sushi can always be stably formed. Further, since the servo motor operates at a determined rotation amount and rotation speed, the tightening can be tightened or loosened appropriately while rotating the rolled sushi with the belt body 28.

  When the third sensor 98 that detects the origin (initial) position of the plate-like sushi rice support / guide body 30 moves the normal plate-like sushi rice M, the third sensor 98 is provided. Is in a position to react. And if it becomes rolling sushi formation operation, the plate-shaped sushi rice support and guide body 30 will be made into an inclination posture with a timer, and the plate-shaped sushi rice P will be supported and guided.

  The squeezing part forming body 31 stands by at a position where the first sensor 96 for detecting the origin (initial) position of the squeezing part forming body 31 reacts, and when the rolled sushi is formed, the squeezing part is formed to a position where the second sensor 97 reacts. The formation body 31 moves and closes the middle part of the plate-shaped sushi rice P from above. However, since the advancement state (closing state) of the throttle portion forming body 31 cannot be adjusted only by the second sensor 97, it is preferable that the second sensor 97 is further moved and adjusted after the reaction of the second sensor 97.

  Next, with reference to FIGS. 14 to 27, the first operation process to the fourteenth operation process (method for manufacturing the spiral roll sushi U) for manufacturing the spiral roll sushi U by the above-described roll sushi manufacturing apparatus A will be described.
