As for this storage part 18, the cutter 13 is arrange | positioned by the lower side opening part, and the arm 19 is attached to the side surface. A measuring mechanism 22 is arranged below the tip of the arm 19, and the storage unit 18, the cutter 3 and the like are supported by the measuring mechanism 22 via the arm 19. This weighing mechanism 22 also measures the cooked rice B in the storage space 15 of the storage unit 18 by the same method using the same weight checker system as that of the above embodiment.
[0023]
Further, the weighing mechanism 24 is also electrically connected to the unwinding motors 10 and 10 via the control mechanisms 23 and 23 in the same manner as described above, and matches the amount of cooked rice B stored in the storage space 15 of the storage unit 18. The driving of the unlocking motors 10 and 10 is controlled, and the rotation of the unlocking rollers 4 and 4 is controlled.
[0024]
In this embodiment, a rotating plate 24 constituting a cooked rice forming machine is disposed below the cutter 13, and a plurality of forming holes 25 are formed along the peripheral edge of the rotating plate 24. And when the cutter 13 opens, the rice B in the storage space 15 of the storage part 18 is filled in each shaping | molding hole 25 of the rotating plate 26 which rotates intermittently.
[0025]
Next, the operation of the present invention will be described.
[First Embodiment]
At the beginning of the supply of cooked rice B, the two feed motors 7 and 7 are driven and the two unwinding motors 10 and 10 are driven. As a result, the two feed conveyors 6 and 6 are rotationally driven to release the cooked rice B and feed it in the directions of the rollers 4 and 4. The delivered cooked rice B is unwound by the two unrolling rollers 4 and 4 that are rotationally driven, and as a result, falls into the storage space 15 in the storage portion 18 as shown in FIG. At this time, the weight of the cooked rice put into the storage space 15 by the cooked rice supply mechanism 22 is measured. Thereafter, by opening the shutter 13, the cooked rice is put into the basket 14 from the storage space 15.
[0026]
By the way, after a certain amount of cooked rice B is put into the bowl 14, either one of the feed motors 7 is driven and the unwinding motor 10 on the side corresponding to the feed motor 7 being driven is driven. Stop the other. As a result, one feed conveyor 6 is driven to rotate, and the unrolling roller 4 corresponding to the feed conveyor 6 is driven to rotate. For this reason, as shown in FIG. 5, the cooked rice B falls into the storage space 15 of the storage unit 18 only from the one side of the unrolling roller 4. In response to this fall, by opening the shutter 13, the cooked rice B can be thrown into the bowl 14. In this case, the supply amount of cooked rice B can be finely adjusted by gradually slowing the rotation of the feed conveyor 6 and the unwinding roller 4.
[0027]
[Second Embodiment]
The process is the same as in the first embodiment until the cooked rice B is supplied into the storage space 15 of the storage unit 18. In other words, the weight of the cooked rice B in the storage space 15 of the storage unit 18 is weighed by the weighing mechanism 22, but at this time, it is not thrown into a large amount of 4 at once, and is once halved, and then the supply ends. Since the supply of cooked rice is gradually reduced at the stage, it is possible to accurately supply a fixed amount of cooked rice. That is, the weight of cooked rice weighed by the weighing mechanism 22 can be as close as possible to the target weight. Further, since the weighing is performed by the weighing mechanism 22 every time, the supply error can be corrected quickly and accurately. The same applies to the first embodiment.
[0028]
Thus, the fixed quantity cooked rice B dropped in the storage space 15 of the storage part 18 can be filled in the forming hole 25 of the forming plate 24 by opening the shutter 13 as in the above-described embodiment. Since the forming plate 24 rotates intermittently, the cooked rice B in the storage space 18 can be sequentially filled into the forming hole 25 in accordance with the opening / closing operation of the shutter 13.
In addition, the cooked rice in the forming hole 25 can be formed into a molded product having a predetermined shape, such as a rice ball containing tools, by a tool filling mechanism or a press mechanism (not shown) in a later process.
[0029]
The present invention is not limited to the embodiment as described above, and various modifications can be made. For example, three or more food feeding mechanisms 3 may be arranged in parallel, and the same number of breaking rollers 4 may be arranged so as to correspond to the food feeding mechanism 3. Further, a structure other than a screw, such as a belt conveyor, can be used as the feed conveyor 6 of the food feed mechanism 3. Furthermore, the container for receiving the cooked rice B may be a wooden box for lunch, a plastic or metal container, or the like. Furthermore, cooked rice forming apparatuses such as a sushi forming machine, a seaweed roll forming machine, and a rice ball forming machine can be used. Furthermore, as food, it can be applied to granular foods other than cooked rice B.
[0030]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists the following effect.
According to claim 1, first, all the food feeding mechanisms and the unrolling rollers are rotationally driven, and then only one food feeding mechanism and the like are rotationally driven, and the rotational speeds of the other food feeding mechanisms and the like are gradually reduced. Since the feed can be stopped at the end, the feed amount can be finely adjusted, and the accuracy of the quantitative supply can be improved.
[0031]
Further, according to claim 2, in addition to the effect of claim 1, since the amount of feed can be detected by the weighing mechanism at one time and the rotation of the food unrolling roller etc. can be controlled, the accuracy of the quantitative supply can be further increased. In addition, the error can be corrected quickly and reliably even if an error occurs.
[0032]
Furthermore, both claims 1 and 2 can be reduced in size, weight, and cost, and can be arranged with a good appearance with the upper part being funky, resulting in improved texture.
