By rotating the feed plate 2a
2, 23 and cutter 28 operate, and the configuration of these operation timings is shown in FIGS. 5A to 5G.
Explain with reference to.

FIG. 5A shows a state in which the feed plates 22 and 23 are closest to each other and at the lowest position, the cutter 28 is closed, and the space between the feed plates 22 and 23 is filled with rice R. From this state, first, the feed plates 22 and 23 move left and right in opposite directions to reach the farthest position (FIG. 5B). Next, the feed plates 22, 23 move upward and reach the uppermost position (FIG. 5C). During this time, the food R remains stationary, maintaining almost its initial shape. Next, the feed plates 22 and 23 move left and right in opposite directions to reach the closest position, and at this time the food R is compacted by both the feed plates 22 and 23 (fifth
Figure D). The cutter 28 opens (Fig. 5E). The feeding plates 22 and 23 move downward together with the rice R,
It reaches the lowest position (Fig. 5F). When the cutter 28 closes, the rice R protruding downward from the outlet 25 is cut off by the cutter 28 and falls, and is supplied to a container (not shown) provided below (Fig. 5G). . After that, the process from FIG. 5B to FIG. 5G is repeated.

As explained above, according to this embodiment, the feed plates 22, 23 and the cutter 28 can be operated at the above-mentioned operation timing by the rotation of the drive shaft 18 and the shaft 32a, and the drive shaft 18
If the shaft 32a and the shaft 32a are connected by a suitable power transmission mechanism such as a sprocket or a chain, all of the components can be operated using a single rotational drive source. Even when interlocking with devices other than this device, such as a container conveyance device for receiving the supplied rice R, it can be similarly operated by a single drive source, and the operation timing can be easily synchronized. be able to. In addition, cam plates 19, 20, 21, 3
By variously changing the shape of the feed plates 22, 23 and the cutter 28, the operation timing and moving speed of the feed plates 22, 23 and the cutter 28 can be appropriately selected.

According to this embodiment, both feed plates 22, 23
have tapered surfaces 22a, 23a, so when these move toward each other, the food R is compressed to some extent, and the feeding portions 22c, 2
3c, it can be made into a substantially rectangular parallelepiped-like grip-like state. Further, the cutter 28 cuts off the rice R protruding downward from the outlet 25 and drops it, and in its closed state, the rice R does not move downward while the feed plates 22 and 23 are operating. It also plays the role of a stopper.

The structure of each part in the above-mentioned embodiment is an example of the present invention, and various structures can be made without being limited to the above-mentioned embodiment. For example, the two cam plates 19 and 20 may be integrally molded, or it is also possible to use a hydraulic cylinder, a solenoid, or the like as the driving source without using the cam plates. It is also convenient to provide a detector near the input port 24 to detect whether the rice R is full, and to control the refilling of the rice R into the input port 24 based on the signal from the detector. .

(Function) According to the present invention, as shown in FIG.
opens, the tip of the rice R is supported on the cutter 28, and while the rice R remains stopped at that position, only the pair of feed plates 22 and 23 move upward as shown in FIG. Both plates 2 as shown in D
2 and 23 approach each other again and press the upper part of the rice R, and in this state, both plates 2 and 23 are pressed together as shown in FIG.
2 and 23 descend by a certain stroke along with the compacted rice R (see E and F in the figure), and both plates 22,
Since the tip R protruding toward the 23 is cut off by the cutter 28, the rice R itself is forced to slide between the pair of feed plates 22 and 23 and to be forcibly fed downward. Instead, the rice R is simply subjected to the compacting action of the pair of feed plates 22 and 23 from the sides. Therefore, the rice R that has been compacted is not forcibly fed by the pair of feeding plates 22 and 23, but the plates 22 and 23 that have compacted the rice R are sent together with the rice R. By descending, a fixed amount of rice R is sent downward.

(Effects of the Invention) According to the present invention, it is possible to obtain an automatic rice feeding device with a simple structure and low cost, which can automatically feed a certain amount of rice by compressing it to a certain extent into a certain shape. Therefore, it is suitable as an automatic sushi rice feeding device in an automatic Inari sushi molding device or the like.

In particular, according to the present invention, as described above, the rice fed between the pair of feeding plates is simply subjected to the compacting action of both feeding plates from the sides, so that the rice is simply compacted by hand. It has a similar finish, can harden uniformly, and can bring out a natural flavor.

Moreover, the compacted rice can be accurately fed in fixed quantities as a fixed quantity molded product by a pair of feeding plates.
