  As shown in FIG. 5 (f), after the material Q is loaded, the material loading press head 33b is moved upward and simultaneously the lateral slide plate 35 is moved backward to return to the original state. Thereafter, the same operation is repeated. It is.

  The sheet-like cooked rice R is conveyed to the float-type final weighing unit 51 by the turntable T, and the sheet-like cooked rice R with the ingredients Q inserted into the tool holes is floated together with the mounting surface S via the load cell 52 and finally weighed. .

  Furthermore, the sheet-like cooked rice R is conveyed to the folding plate 5 position by the turntable T, the sheet-like cooked rice R is introduced inside the U-shaped frame of the folding insertion frame 8, and the sheet-shaped cooked rice R is moved by the forward movement of the folding insertion frame 8. It is transferred onto the folding plate 5 through the front gate part.

  Further, the turntable T is rotated and another sheet-like cooked rice R is introduced into the U-shaped frame inside the folding insertion frame 8.

  The link mechanism is activated, and the left and right folded pieces of the folding plate 5 are folded inward from each other via the center surface to fold the sheet-like cooked rice R into a substantially triangular shape.

  After folding, the left and right folded pieces open. Then, by the operation of the crank link mechanism, the folding insertion frame 8 moves forward, the sheet-like cooked rice R on the turntable T is held inside the U-shaped frame of the folding insertion frame 8, and the sheet is moved to the folding plate 5 position by the extruded piece. The cooked rice R is moved.

  At the same time, the pressing mold outside the U-shaped frame of the folding insertion frame 8 slides, so that the sheet-shaped cooked rice R folded in a substantially triangular shape on the folding plate 5 is turned into a rice ball molding hole of the vertical molding table 6. insert.

  The folding insertion frame 8 is raised and retracted toward the turntable T, and lowered to the original placement surface S. At this time, the next sheet-like cooked rice R is waiting due to the rotation of the turntable T (mounting surface S).

  When the sheet-like cooked rice R is inserted into the rice ball forming holes of the vertical forming table 6, the vertical forming table 6 rotates to the pre-forming position and is pre-formed by the pre-forming mold 10.

  Then, the vertical molding table 6 is rotated to the main molding position and is finally molded by the main molding die 12.

  Next, the vertical molding table 6 rotates to the discharge position, and the rice balls after the main molding are discharged from the rice ball forming holes to the discharge conveyor 9 by the discharge mold 11.

  The discharged rice balls are transported by the carry-out conveyor 9 and manually taken out and then packed, or are automatically transported to the rice ball packaging process and then automatically packed there to become a finished product.
