Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a rice ball forming machine,
More specifically, the rice ball is well supplied to the rice ball forming table, and the rice ball forming table can be efficiently formed by the rice ball forming table that rotates the rice ball having a constant weight intermittently. Regarding the machine.

[0002]

2. Description of the Related Art Generally, a rice ball forming machine has a rice ball forming table which is detachably pivoted on a base fixedly set on a base frame and intermittently rotates, and a rice ball forming table. It is equipped with a rice supply device that supplies rice to each rice ball forming hole that is drilled at a prescribed interval in the peripheral portion, and a carry-out device that carries out the rice ball formed in the rice ball forming hole of the rice ball forming table and controls these. Connected to the device, configured, triangle,
Various shapes such as squares and straws are automatically formed.

[0003]

However, in the conventional rice ball forming machine of this type, the weight of the rice ball is not measured during forming, but some of the formed rice balls are measured, and the weight of the rice ball is approximately constant. Since the formed rice balls have different weights, the rice is often wasted.

When forming rice balls of various shapes such as a triangle, a quadrangle and a straw shape, it is necessary to supply various shapes of rice to the rice ball forming holes of the rice ball forming table. Therefore, it is necessary to replace not only the rice ball forming table each time the shape of the rice ball changes, but also the guide roller and the feeding roller that supply the rice to the rice ball forming table. Cannot be molded efficiently.

Further, the rice supplied from the hopper to the rice ball forming table has not been sufficiently loosened yet, and the rice ball supplied to the rice ball forming hole of the rice ball forming table is cut into one piece. Since the cutter pushes the rice all the way through, the rice is wasted and
There is a problem that rice is scattered around the rice ball forming machine and becomes dirty.

Further, since the Geneva stop mechanism is used to intermittently rotate the rice ball forming table, the rotation distance may shift during repeated use, and the interlocking mechanism is entirely external. Since it is exposed to the inside and grease can be injected, it cannot be washed with water after use, and cleaning cannot be performed easily.

The rice ball forming machine of the present invention has been made in view of the above situation, and the rice ball can be supplied to the rice ball forming table well, and the rice ball having a constant weight without wasting rice can be compared with the rice ball forming machine. Even if the shape is different, intermittent rotation can be performed accurately with the rice ball forming table, and the surroundings are not contaminated during the rice ball forming process. It is intended to provide a rice ball forming machine that can be washed.
