BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a preforming mechanism of a rice sand making apparatus.

[0002]

2. Description of the Related Art At present, there has been proposed a diaper sandwich in which ingredients are interposed substantially over the entire surface between a lower rice body and a upper rice body, and the mass demand of the diaper sand is met. For this reason, automation of a method and a machine for producing rice ball sand has been promoted.

[0003] Conventionally, the above-mentioned method for producing a rice ball sand is a method in which only a single turntable mold is used. A method in which molding is performed using only the mold that is transported by the transport mechanism. It has been known.

In the above-mentioned manufacturing method, a predetermined amount of cooked rice is supplied into a molding die, and the rice is pressed in the molding die to form a lower rice body. After supplying the ingredients, supply the same amount of cooked rice to the ingredients in the mold, and press the cooked rice on the ingredients in the mold together with the ingredients and the ingredients to be the same as the ingredients. The shape of the body
A rice ball sand is manufactured by integrally molding with a rice cooker and ingredients. That is, according to the above two methods, the lower rice body forming, the supply of the ingredients, and the integral molding of the lower rice body and the ingredients with the upper rice body are sequentially performed by one molding die.

However, in both of the above-mentioned conventional methods and apparatuses, when pressing the cooked rice on the ingredients to form the upper rice body, the compressive force is dispersed to the lower ingredients and the lower rice body to compress the rice. Insufficiently, the compression and diffusion of cooked rice with respect to the mold may be insufficient, and the cooked rice body may not be formed in the same shape as the cooked rice body, resulting in variation in the shape of the rice ball sand, or Since the body is pressed twice during molding itself and when shaping the rice body, the lower rice body is overpressed, and the lower rice body and the upper rice body have different cooked rice pressed densities and are uniform. Not only is it difficult to obtain compressed (rice cooked rice) rice ball sand, but also the upper rice body is liable to collapse, resulting in lower commercial value.

Therefore, in order to solve the above-mentioned problem, the lower rice body and the upper rice body are separately formed by separate molding dies, and the ingredients are placed on the lower rice body and then the upper rice body is combined. , It is easy to make high quality rice sand with constant hardness (uniform compression) and shape from lower rice body to upper rice body,
An apparatus and a method for producing rice ball sand that can be produced reliably and have been proposed by the present applicant.

[0007]

However, even in the above-mentioned apparatus for manufacturing rice ball sand, there is a case where the molding of the lower rice body and the upper rice body varies in terms of the compressed rice rice density and the shape.

According to the present invention, the above-mentioned rice-and-rice sand manufacturing apparatus is equipped with the above-mentioned rice-and-sand sandwiching apparatus, so that the lower rice body and the upper rice body that can sufficiently satisfy the compression, diffusion and shape of cooked rice can be formed. It is an object of the present invention to provide a pre-forming mechanism of a diaper sand manufacturing apparatus which can easily and surely manufacture a higher quality diaper sand by a manufacturing apparatus.

[0009]

In order to achieve the above-mentioned object, a preforming mechanism of the apparatus for manufacturing a rice ball sand according to the present invention comprises a first molding die of a first turntable and a second turntable. The lower rice body and the upper rice body are separately formed in the second molding die of the bull, and the ingredients are supplied on the lower rice body, and the lower rice body and the ingredients in the first molding die and the upper rice body in the second molding die are formed. A pre-forming mechanism of a rice sand making apparatus provided so that a rice body and a molding die are combined by a press mechanism at a position where the two molds communicate with each other. The first and second pre-formed frames formed by communicating the pre-formed dies in the recesses in the recesses so as to be able to advance and retreat in the front-rear direction by the driving mechanism are respectively connected to the first pre-formed frames. A concave portion of the forming frame, a first cooked rice supply mechanism for supplying cooked rice to the first mold, and a second cooked rice supply mechanism. The concave portion of the pre-formed frame and the second cooked rice supply mechanism for supplying cooked rice to the second forming die are communicated with each other in the up-down direction so as to coincide with each other. It is characterized in that the preforming dies of the first forming die and the second preforming frame and the one second forming die are arranged so as to coincide with and communicate with each other in the respective vertical directions.

[0010]

The cooked rice in the cooked rice hopper is scraped off by a stirring bar and transported to the first and second cooked rice supply mechanisms. When a predetermined amount of cooked rice is supplied into the recesses of the first and second preforming dies by the first and second cooked rice supply mechanisms, the presser die at the retracted position in the recesses is advanced by the drive mechanism, and the cooked rice is fed. It presses and moves from the inside of the recess toward the first and second preforming dies and compresses it. Thereby, the cooked rice is preformed into a predetermined shape (for example, a triangle) by the first and second preforming dies and the pressing die. After the preforming, the holding dies of the first and second preforming frames are immediately retracted by the drive mechanism, and stand by at the positions, in preparation for the next preforming.

[0011] The preformed rice in the first preforming die is extruded downward by the first press head, pushed into the first molding die of the first turntable, and pressed to form the lower rice body. Molded.

On the other hand, the preformed cooked rice in the second preforming mold is extruded downward by the second press head, pushed into the second molding die of the second turntable, pressed, and then pressed. A rice body is formed. The lower rice body and the upper rice body have the same amount of cooked rice and are formed into the same shape.

The first turntable is intermittently rotated by a predetermined angle unit, and when the lower rice body is rotated and conveyed to a predetermined position, the component filling mechanism covers the entire upper surface of the lower rice body in the first molding die. Ingredients are supplied. The first turntable is
Furthermore, it is intermittently rotated in the same direction.

On the other hand, the second turntable is also intermittently rotated in the same direction as the first turntable by a predetermined angle unit, and a second molding die of the second turntable includes: First turn
Since the first molding die of the table is provided so as to coincide with the vertical arrangement at a predetermined position, when the second molding die coincides with the first molding die at the predetermined position, the lower rice body is pushed up by the press head. The upper rice body is removed from the first molding die and is pushed into the second molding die, and at the same time, the lower rice body and the ingredients and the upper rice body are pushed down by the press head, so that the second rice mold is removed. It is combined in a second mold of the table, thereby producing a rice ball sand.

When the second mold comes to a predetermined position due to the intermittent rotation of the second turntable, the press-down head operates to push out the sand from the inside of the second mold. When packing the sand with a laver sheet, the diaper sand is rotated and transported to the position of the laver sheet supply device without being extruded from the inside of the second mold, while being packed in the second mold. At the position, it is lifted up from the second molding die by the press head and removed from the mold, and wrapped in a laver sheet.
