As a result, the preceding lump of cooked rice R1 positioned in the conveying frame portion 21b is opened on the downstream side in the conveying direction, and the next lump of cooked rice R2 introduced into the introduction frame portion 21a is regulated from both sides.

Next, as shown in FIG. 27, when the moving frame 21 moves from the introducing position to the molding position and the moving plate 25 pushes the next cooked rice lump R2, the preceding cooked rice lump R1 is placed on the belt conveyor 12. After the sesame seeds are shaken by the sesame shaker 13, the rice mass R2 is transported to the next process, and the cooked rice mass R2 moves directly above the forming hole 22c.

Thereafter, the moving frame 21, upper mold 23, lower mold 24 and moving plate 25 sequentially repeat the operations shown in FIGS. become.

Also in the cooked rice forming apparatus M of Embodiment 2, the moving frame body 21 moves from the separated state to the combined state at the introduction position, moves to the forming position, and moves from the combined state to the separated state during the forming operation at the forming position. , it passes through both sides of the arm portion 23-1 for raising and lowering the upper molding die 23 and moves to the introduction position. As a result, the moving frame 21 can return from the forming position to the introduction position during the forming of the cooked rice lump R, so that the next cooked rice lump R can be introduced without waiting for the completion of the forming of the preceding cooked rice lump R. This makes it possible to speed up the process of forming the lump of cooked rice R.

Further, according to the cooked rice forming apparatus M of Embodiment 2, the moving frame body 21 is in the separated state at the introduction position, and since the cooked rice mass R is introduced into the introduction frame portion 21a, the moving frame body 21 moves to the combined state. It is possible to introduce the boiled rice mass R without being restricted by the width and position of the frame 21. - 特許庁

Although the invention made by the present inventor has been specifically described based on the embodiments, the embodiments disclosed in this specification are illustrative in all respects and are limited to the disclosed technology. is not. That is, the technical scope of the present invention should not be construed in a restrictive manner based on the description of the above embodiments, but should be construed according to the description of the scope of claims. All modifications are included as long as they do not deviate from the description technology and equivalent technology and the gist of the claims.

For example, in Embodiments 1 and 2, the moving frame 21 can be separated and coupled to each other in the direction intersecting the moving direction at the partition portion 21s. This is because, in Embodiments 1 and 2, the arms 23-1, 23a-1, and 23b-1 for lifting and lowering the upper molding dies 23, 23a, and 23b are positioned substantially at the center of the conveying width of the lump of cooked rice R. Therefore, when the moving frame 21 returns from the forming position to the introduction position, it can pass through both sides of the arm portions 23-1, 23a-1, and 23b-1 if separated at the partition portion 21s. Because it becomes

Therefore, when the arm portions 23-1, 23a-1, and 23b-1 are shifted from the substantially central portion of the conveying width of the lump of cooked rice R, the separating position of the moving frame 21 is not the dividing portion 21s. It does not have to be, and it can be, for example, between one width restricting portion 21f and the partition portion 21s.

The cooked rice forming apparatus of the present invention can of course be used alone, but it is also possible to connect a cooked rice forming apparatus for forming a predetermined weight of cooked rice to the previous stage, or to place the formed lumps of cooked rice in a box lunch container or the like. It is also possible to further promote automation of production by connecting a device for serving cooked rice to the rear stage.
