Next, as shown in FIG. 8, when the cooked rice R reaches a predetermined position (moldable position by the molding die 30) on the fourth conveyor C4, the transport operation of the fourth conveyor C4 is stopped, and a pair of conveyors C4 are stopped. The first mold members 30a and 30a are moved to the descending end (that is, the position where they come into contact with the fourth conveyor C4).

Then, as shown in FIG. 9, the pair of second mold members 30b and 30b are moved in the direction of approaching each other, the third mold member 30c is lowered, and finally the first located rearward in the cooked rice transport direction. The mold member 30a of No. 1 is moved in a direction approaching the other first mold member 30a. As a result, the cooked rice R is formed into a quadrangle smaller than the cooked rice input region T1 of the container T shown in FIG.

When the molding of cooked rice R is completed, the mold driving unit 33a is moved in a direction orthogonal to the transport direction of the fourth conveyor C4, so that the first mold members 30a, 30a, as shown in FIG. The second mold members 30b and 30b and the third mold member 30c are integrally moved in the horizontal direction, and are directly above the cooked rice charging region T1 of the container T positioned on the cooked rice feeding portion M4 on the cooked rice R transport path. Position the cooked rice R so that the position comes. Needless to say, when the molding completion position of the cooked rice R on the fourth conveyor C4 is the position directly above the cooked rice charging region T1 of the container T, it is not necessary to move the mold driving unit 33a.

After positioning the cooked rice R, as shown in FIG. 11, the first mold member 30a located rearward in the cooked rice transport direction is moved rearward. Subsequently, as shown in FIG. 12, the first mold member 30a located in the front in the cooked rice transport direction is raised, and the first mold member 30a located in the rear in the other cooked rice transport direction is raised and further moved backward. Let me. Further, the pair of second mold members 30b and 30b are moved in a direction in which they are separated from each other, and the third mold member 30c is raised.

Finally, as shown in FIG. 13, the transport operation of the fourth conveyor C4 is restarted to transport the cooked rice R to the cooked rice loading section M4, which is the next step, and the molded mold drive section 33a is returned to the fixed position. Introduce the next cooked rice R.

In the molding unit M3 of the present embodiment, the cooked rice R is positioned after being molded, but the molding and the positioning may be performed at the same time.

The cooked rice R that has been molded in the molded portion M3 in this way is conveyed to the cooked rice charging portion M4.

The process of adding cooked rice R by the cooked rice charging unit M4 will be described with reference to FIGS. 14 and 15. Here, FIG. 14 is an explanatory view showing how the cooked rice R is guided to the shutter plate 40 by the positioning portion 41, and FIG. 15 is a state in which the cooked rice R is opened into the cooked rice charging region T1 of the container T with the shutter plate 40 opened. It is explanatory drawing which shows.

As described above, in the cooked rice charging section M4, the container T sent from the container supply section M2 is installed in the container setting section 42. As shown in FIGS. 14 and 15, the cooked rice R from the molding portion M3 is pushed by the rear positioning member 41b along the rice transport direction and comes into contact with the front positioning member 41a, so that the cooked rice R is a shutter plate. On 40, it is positioned directly above the cooked rice charging region T1 of the container T. Then, when the shutter plate 40 moves to the open position, as shown in FIG. 15, the cooked rice R on the shutter plate 40 is automatically dropped and thrown into the cooked rice charging region T1 formed in the container T.

The container T into which the cooked rice R is charged in the cooked rice charging section M4 is weighed by the total weight measuring section M5, and when the total weight of the container T is within a predetermined range, the cooked rice is sorted by the container sorting section M6. It is distributed to the leveling section M7. Then, the cooked rice R charged into the container T is leveled by the cooked rice leveling unit M7 and sent to the next step (for example, a side dish serving step). When the total weight of the container T is out of the predetermined range, the container T is sent to the container discharge unit M8 by the container distribution unit M6, and is discharged from the discharge conveyor 80 to the outside of the device.

As described above, in the molding unit M3 of the present embodiment, the molding mold driving unit 33a for driving the plurality of molding dies 30 for molding the cooked rice R and the molding mold driving unit 33a are orthogonal to the transport direction of the fourth conveyor C4. A position adjusting unit 33b that can move in the direction is provided, and the mold driving unit 33a and the position adjusting unit 33b are controlled by the control unit 33 to have a shape corresponding to the cooked rice input region T1 formed in the container T and cooked rice. Since the cooked rice R is formed by adjusting the position so that the position directly above the cooked rice charging region T1 is on the transport path of the cooked rice R, the cooked rice R can be formed regardless of the position of the cooked rice charging region T1 formed in the container T. It will be possible to put it in automatically.

Further, as shown in FIG. 16, the shape of the region surrounded by the first mold members 30a, 30a and the second mold members 30b, 30b (that is, the shape of the cooked rice R to be molded) is the first mold member. Various changes can be made by making the positional relationship between the 30a and 30a and the second mold members 30b and 30b variable. As a result, the cooked rice can be automatically charged into a plurality of types of containers T having different shapes of the cooked rice charging region T1.

Here, for example, if the first mold member 30a located rearward in the rice transport direction can be replaced with another mold member having a different shape, the cooked rice R can be changed as shown in FIGS. It can be molded into a wider variety of shapes.

That is, as shown in FIG. 17B, the rear first mold member 30a shown in FIG. 17A should be replaced with the first mold member 30a having a substantially triangular shape in a plan view having an inclined molding surface. For example, since the substantially triangular cooked rice R is formed, it is possible to correspond to the cooked rice input region formed in the triangle.

Further, as shown in FIGS. 17 (c) and 17 (d), if the first mold member 30a having a short length is replaced, a quadrangle or cooked rice R elongated in the transport direction is formed.

The first mold member 30a located rearward in the rice transport direction is not limited to being replaceable, and other mold members may be replaceable, and a plurality of mold members may be replaceable. May be good.
