Description

[Detailed description of the device]

The present invention relates to an improvement of an apparatus for reliably and automatically supplying a certain amount of rice for producing nigiri rice, Inari sushi, bento and the like.

[0002]

[Prior art]

 As shown in Japanese Examined Patent Publication No. 63-49980 and Japanese Utility Model Publication No. 61-75236, the upper part is inclined outward as a means for quantitatively supplying cooked rice to produce nigiri rice, Inari sushi, bento, etc. A pair of rice feed plates, which are vertically and oppositely movable up and down, are provided with a moving mechanism for moving them inward at the rising position and outwardly at the descending position, and at the same time, the pair of rice feeding plates at the descending position. It is known that a pair of open / close shutters, which are opened when the plate is lowered, are installed at the lower end of the plate, and a fixed amount is supplied downward by the open / close action of the open / close shutter while pressing and pressing the rice between the pair of rice feed plates. .

By the way, recently, nigiri rice is wrapped in a film containing seaweed, and when eating, the film is separated from the central part to the left and right, and the separated film is detached to the left and right, so that the internal seaweed is automatically added to the surface of the nigiri rice. It is known that nigiri rice is made by wrapping it in seaweed before meals without touching it with hands. However, when the film separated in the central part is released to the left and right, the rice adheres to the film and the left and right film detachment operations cannot be performed smoothly, and the seaweed encapsulation action also occurs. Since there is an insufficient defect, it is considered that oil is mixed in the rice so that the rice does not adhere to the film.Currently, it is not limited to nigiri rice so that rice does not adhere to containers and so on, inari sushi, bento It is also practiced to mix oil with rice.

[0004]

[Problems to be solved by the device]

 However, when trying to supply a fixed amount of this oil-containing rice with the above-mentioned automatic rice feeder, the slip between the rice and the rice feed plate becomes too good, and especially the rice feed plate that is compacting the rice is clamped down and transferred. Due to the inertia of time, it becomes uncertain whether or not the rice will be fed in a fixed amount, and this tendency becomes more noticeable as the speed of raising and lowering the rice feed plate is increased to improve work efficiency. In view of these circumstances, it is an object of the present invention to provide an automatic rice feeding device capable of reliably feeding a fixed amount of such slippery rice mixed with oil.

[0005]

[Means for Solving the Problems]

 For the above-mentioned purpose, the present invention provides a pair of rice feed plates which are inclined upward and outward and are opposed to each other in a vertical direction, and are moved inward in a raised position and outward in a lowered position. A pair of open / close shutters that open during the lowering action are installed at the lower ends of the pair of rice feed plates in the descending position, and a pair of rice fed between the pair of rice feed plates is provided. In the automatic rice feeder for fixed amount feeding by the closing action of the opening / closing shutter, a plurality of uneven ridges are provided horizontally at appropriate intervals on the inner surfaces facing each other of the pair of rice feeding plates. To do.

If a partition plate that moves up and down together with the rice feed plate is provided in the center between the pair of rice feed plates, two pieces of rice are fed in a fixed amount at the same time between the side surfaces of the partition plate and the pair of rice feed plates. The efficiency can be further improved. Further, the uneven line may be formed integrally with the rice feed plate or may be attached separately, but it is usually preferable to form the convex line. In the present invention, however, the vertically moving mechanism of the pair of rice feeding plates and the inward or outward moving mechanism at the ascending position and the descending position may be any of the conventionally known ones.

[0007]

[Action]

 According to the present invention, the rice that is supplied between the pair of rice feed plates that are in the raised position and are spaced apart from each other is fixed by the inward movement of the pair of rice feed plates, and then the pair of open / close shutters At the same time as opening, the pair of rice feeding plates descends, so that the uneven strips hold the rice compacted between them without sliding, and the lower end is projected from the opening / closing shutter for a certain amount, so that the pair of opening / closing shutters Is closed and the protruding rice is separated and supplied downward, and then the pair of rice feed plates moves outward and separates from the rice and rises to return to the separated state of the elevated position again. Then, the next fixed amount supply operation is repeated.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A partition plate 4 and A pair of rice feed plates 5 and 5, which are opposed to both sides thereof and whose upper portions are respectively inclined outward, are provided so as to be simultaneously moved up and down by an arbitrary lifting mechanism 6, and the pair of rice feed plates 5 5 is further provided with a moving mechanism 7 that moves inward in the ascending position and moves outward in the descending position, and the moving mechanism 7 and the elevating mechanism 6 are interlocked with each other, and their interlocking modes When the pair of rice feed plates 5.5 reach the upper position, the moving mechanism 7 operates to move the pair of rice feed plates 5.5 inwardly to press and solidify the rice inside, Rice feeding plate 5 It is configured to pair rice feed plate 5.5 by the moving mechanism 7 to reach descending position away from the rice that has been compacted by moving outwardly from one another.

As an example of the elevating mechanism 6, the levers 10 and 10 provided on the pair of rice feed plates 5 and 5 are respectively pulled upward by a spring 11 and are supported between the levers 10 and 10. The roller 12 can be intermittently pressed downward by the rotating cam 13 so that the rice feed plates 5 and 5 can be moved up and down, and the moving mechanism 7 includes the rice feed plates 5 and 5. The support pieces 14 and 14 provided on the support shaft 15 are slidably fitted on the support shaft 15 so that both support pieces 14 and 14 can be pulled inward by the spring 16 and the expansion cam between the support pieces 14 and 14 can be extended. 17 and 17 'are provided so that the support cams 14 and 14 can be intermittently expanded outward by the expansion cams 17 and 17' so that the pair of rice feeding plates 5.5 can be moved inward. It is configured so that it can be lowered with Has been done.

Further, the opening / closing operation of the pair of opening / closing shutters 1.1 is interlocked with the elevating mechanism 6 so as to be opened only when the rice feed plates 5.5 are moved downward. There is no difference from the invention described in the known Japanese Utility Model Publication No. 1-8143.

The feature of the present invention is, however, that a plurality of horizontal ridges, ribs 8, 8 ... Are provided integrally or separately on the inner surfaces of the pair of rice feed plates 5, 5 facing each other at appropriate intervals. , When the pair of rice feed plates 5, 5 move inward as described above to press and solidify the rice, the rice pressed by the inertia of the rice slides against the rice feed plate 5. It is formed so as to protrude from the open / close shutter 1.1 while maintaining a predetermined amount of clamping pressure. Reference numeral 9 in the drawing denotes a rice supply conveyor, and it is preferable that the pair of rice feed plates and partition plates be coated with ethylene tetrafluoride resin so that rice does not adhere thereto.
