First, when the power switch provided on the operation panel P is turned on, the stirring rod 24 in the hopper 2 starts to rotate. Add sushi rice that has been mixed with sushi vinegar in advance.

  Sushi rice thrown into the hopper 2, while being understood by stirring arm 24, is supplied to the top rolling roller pair 31 of the rolling unit 3. Then, the operator operates the operation panel P, after setting the winding thickness and number of sushi, press the start button.

  When the start button is operated, a control unit (not shown) issues a command to the rolling unit 3 to rotate the upper rolling roller pair 31 and the lower rolling roller pair 32 in the feeding direction. The sushi rice introduced into the rolling unit 3 is first roughly rolled by the upper rolling roller pair 31 and then fed to the next lower rolling roller pair 32 and formed into a high-density plate shape by the lower rolling roller pair 32. The

  At the same time, the control unit issues a command to the drive motor of the slider 41 of the molding stage 11 and makes the slider 41 stand by with the third rotating plate 54 of the winding plate 5 positioned under the rolling unit 3.

  When the sushi rice is washed away from the downstream of the rolling unit 3, the control unit slides the winding plate 5 forward (rightward in FIG. 2) in accordance with the flow rate of the sushi rice, and each pressing plate of the winding plate 5. Lay out sushi rice among members 71-73. When the sushi rice is fed out for a predetermined length, the control unit pushes the cutting blade 642 to cut the sushi rice.

  When the sushi rice is supplied onto the roll rice bran plate 5, the cooked rice forming apparatus 1 once enters a standby state. During this waiting time, the worker arranges a laver sheet and ingredients on the sushi rice (supplying process). When the arrangement of the ingredients is completed, the operator presses a winding process start button (not shown) on the operation panel P. Instead of winding process start button, after the rolling step is completed, it may be timer controlled to shift automatically to the winding step after a period of time.

  When the winding process is started, the control means first confirms again whether the curl plate 5 is in a predetermined position on the plate driving means 6, and then the control means instructs each drive motor of the plate driving means 6. send.

  With this command, the first lift plate 61 and the second lift plate 61 are pushed up independently of each other. As the first lift plate 61 rises, the first cam member 56 of the third rotation plate 54 comes into contact with the upper surface of the first lift plate 61 and is pushed up, so that the first rotation plate 52 and the third rotation plate rotate. The plate 54 is lifted while maintaining a horizontal state.

  When the second lift plate 62 is raised, first, the cam roller 572 of the second cam member 67 of the second rotation plate 53 is pushed up against the upper surface of the second lift plate 62, and the second rotation plate 53 gradually moves. It will be lifted. Accordingly, as shown in FIG. 5B, the sushi rice is gradually lifted up at both ends of the base plate 51.

  When the second lift plate 62 is further raised, as shown in FIG. 5C, the second lift plate 62 leaves the cam roller 572, and the second lift plate 62 is in the uppermost position while being in contact with the next cam roller 573. The second rotation plate 53 is in an upright state with respect to the base plate 51.

  In this state, when the second and third pressing plate members 72 and 73 enter the front surface side of the base end surface 711 of the first pressing plate member 71, as shown in FIG. They are faced together and completely block both ends of the sushi roll.

  When the first lift plate 61 continues to rise to the uppermost position, the third rotating plate 54 is a U-shaped space formed by the base plate 51, the first rotating plate 52, and the second rotating plate 53. It is folded as it is pushed inward.

  Accordingly, the placed sushi rice on the rolling-up bamboo plate 5 is shaped into a rod pushed from above by the third rotating plate 54. At that time, both ends of the rolled sushi are completely pressed by the second and third pressing plate members 72 and 73, so that the ingredients in the middle can be prevented from protruding to both sides by the tightening force. Moreover, since both ends are pressed down, the density of cooked rice and ingredients from the center to both ends can be made uniform, and the appearance when cut is good.

  As described above, when the series of operations is completed, the cooked rice forming apparatus 1 again enters the standby state. Finally, the operator By recovering the seaweed roll molded into bars on the rolling-up bamboo plate 5, a series of work steps are all completed.

  In addition, when making the “back roll” with the cooked rice on the front side, the curl plate 5 is temporarily returned to the horizontal state, and after the operator performs “position change” to rotate the formed sushi rice by 90 °, the above-described process is performed. By repeating the series of operations again and deforming the curl plate 5 into a cylindrical shape, a spiral back winding can be performed. The sushi rice repositioning operation may be performed automatically instead of manually.

  Moreover, in this example, the cooked rice forming apparatus 1 rolls the sushi rice in the rolling unit 3 and forms it into a rod shape in the molded unit 4, but automatically collects the ingredient charging device and the rolled up sushi rice. A recovery device or the like may be further provided, and as long as the basic structure of the present invention is included, those modified examples are also included in the present invention. Moreover, the size of the rolled candy plate may be arbitrarily selected according to the size and diameter of the rolled sushi.

  Furthermore, in this example, the cooked rice forming apparatus is described taking as an example a molding apparatus that automatically performs a series of steps from the supply of cooked rice to molding. However, if the roll rice plate structure of the present invention is provided, , rolling-up bamboo may be a plate alone only consisting configuration, even driving method of winding bamboo plate is automatic, may be manual.
