BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for feeding food materials, and more particularly to an apparatus for discharging cooked rice or other viscous substances in the production of rice balls, rice balls and the like.

[0002]

2. Description of the Related Art A conventional apparatus for supplying cooked rice and other viscous food materials is performed by a screw mechanism or a piston cylinder, and a conventional example similar to the present invention is disclosed in Japanese Patent Publication No. 39-12276. There is a book in which the same type of conical rollers are arranged in a ring shape with the large-diameter portion facing downward and the direction of the axis perpendicular to the roller. Further, a brief description will be given of a food material delivery device which has been already implemented by the applicant of the present invention.

The above-mentioned food material feeding device has a casing, and a plurality of vertical rollers arranged in an annular shape are provided in the casing in order to convey the outer food material (for example, bun dough) downward while rotating. Each is provided rotatably. Here, the rotation center lines of the plurality of vertical rollers are inclined to one side with respect to the vertical direction so that a funnel-shaped space whose upper side is wider than the lower side is formed inside the plurality of vertical rollers. The discharge ports are formed inside the lower ends of the plurality of vertical rollers.

[0004] In the space, a transport pipe for transporting the inner food material (for example, bean paste) is provided extending in the vertical direction, and a discharge port is provided below the transport pipe. A joint is formed between the outlet and the outlet to join the outer periphery of the inner food material and the outer food material.

Accordingly, the outer food material is supplied to the inside of the plurality of vertical rollers, and by rotating the plurality of vertical rollers, the outer food material is conveyed and sent downward while turning. In addition, by discharging the inner food material from the outlet while rotating the transport pipe, the inner food material is sent to the joint while rotating. As a result, the outer periphery of the inner food material and the outer food material are joined at the joint, and the inner and outer food materials are discharged downward from the discharge port.

[0006]

However, in the conventional apparatus, food materials, for example, viscous materials such as steamed buns and cooked rice stick or stick to the passage of the feeding device, and it is difficult to supply the food stably. is there. Also,
There is a problem that the quality is deteriorated due to excessive stirring and crushing of the rice grains during the supply. Further, even when a plurality of food materials are formed by discharge molding, a bar-shaped dough having a predetermined shape cannot be discharged stably.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the feeder according to the present invention, a supply pipe is provided below and connected to a food material supply section for supplying a food material from above to below. A scraper of food material is provided in sliding contact. As the food material supply unit, for example, a plurality of supply rollers are erected in an annular shape, and the upper part of a vertically formed enclosure passing through the central axis of the annular shape is widened and narrowed downward to form a funnel shape. Like that.

The surface of the supply roller is formed as an uneven groove in order to prevent slipping or sticking when the contacting rice material is supplied downward. The shape of the concave and convex grooves on the supply roller surface is provided with vertical grooves and spirals provided in the longitudinal direction of the roller,
Alternatively, it is effective to provide a large number of small hemispherical dents and protrusions. By making the surface of the supply roller uneven, the surface in contact with the cooked rice is reduced, so that sticking can be prevented. In addition, the unevenness of the surface can surely guide and supply the cooked rice downward without slipping.

The supply pipe is provided with a scraper for removing cooked rice adhering to the inner peripheral surface of the pipe in proximity to or in sliding contact with the inner peripheral surface of the pipe. Since the scraper preferably has a shape that covers the entire inner peripheral surface of the pipe, for example, a wire-shaped scraper is provided in a spiral shape so as to be close to or in sliding contact with the inner circumference of the pipe. This scraper is separate from the inside of the supply pipe so that the scraper relatively moves on the wall surface inside the pipe. When the cooked rice passes through the supply pipe, the scraper and the wall around the pipe move relatively, so even if the cooked rice sticks to the wall, the scraper scrapes the cooked rice and the spiral shape of the scraper moves the cooked rice downward. The action of sending out works.

The entrance of the outer shell material D1 of the housing inner chamber 31a is provided on the side surface of the housing 31, and the outer shell material supply unit 10 and the outer shell material passage tube 13 are connected. The rotating ring 33 is fitted into the opening on the lower surface of the housing 31, and the positional relationship is such that the central axes of the supply pipe 32 and the rotating ring 33 are the same axis and coincide with the central axis of the surrounding space. Further, the tip of the supply pipe 32 and the rotating ring 33 are separated by a predetermined gap,
It has an annular gap C. This annular gap C is a skin material D1.
Outlet. The supply pipe 32 and the rotary ring 33 rotate in the same direction via gears 34 by the drive transmission from the motor 22.

Therefore, the outer skin material D1 sent from the outer skin material passage tube 13 is supplied to the housing inner chamber 31a and discharged from the annular gap C, and the inner packaging material D2 is rotated by the supply rollers 21. Supply pipe 32 driven by rotation
And is discharged from below through the supply pipe 32, and formed and discharged as a double rod.

A spiral scraper 35 is provided inside the supply pipe 32, and the upper end of the scraper 35 is fixed to the housing 31, so that the scraper 35 does not rotate even if the supply pipe 32 rotates. It is separate from. When the shape of the scraper 35 is a spiral shape, in addition to preventing the inclusion material on the inner peripheral surface of the supply pipe 32 from adhering, the scraper 35 can be rotated relative to the supply pipe 32 to move the inside of the pipe. The effect of pushing the inner packaging material D2 downward acts.

The envelope cutting section 40 is implemented, for example, as shown in Japanese Patent Publication No. Hei 4-53453 by the present applicant. In other words, three or more rectangular pieces are slidably assembled with each other to form an enclosure at the center, and the enclosure is opened and closed to cut the food material passing therethrough. Six identically shaped rectangular pieces 41 are housed in a case 42 and a drive rod 4 movably attached to the case 42.
