A food supply hole 61 is formed above the two guide members 12.

Next, the operation of the food molding machine configured as described above will be explained.

First, push down the other end of the bell crank 21b (the part protruding from the housing 5). Then, the bell crank 21b rotates about the fulcrum shaft 21a, and the horizontal shaft 21 moves away from the horizontal shaft 22 against the force of the spring 30. Therefore, since a space is created between the rotor 19 and the rotor 20, extruded sheets 19a and 20a made of endless sheet-like belts are loosely fitted to the rotors 19 and 20, respectively, to reduce the downward pushing force of the bell crank 21b. release. Then, the force of the spring 30 causes the rotor 19 to return to its original position together with the horizontal shaft 21.

Therefore, when the handle 42 is turned in a predetermined direction, the rotation shaft 41, the worm 43, the worm wheel 39,
The rotation transmission plate 32 rotates via the horizontal shaft 22, and in conjunction with this, the rotation transmission plate 36 rotates while circumscribing the rotation transmission plate 32 due to the biasing force of the spring 30.

At the same time, the rotor 20 and stepped pulley 31 rotate. When the stepped pulley 31 rotates,
Belt 49, small pulley 48, gears 53, 44, 4
5, rollers 14 and 15 rotate in the directions of arrows A and B shown in FIG. 1, respectively. Also at this time,
The large pulley 4 also rotates via the belt 50. Note that at this time, the cylinder 56 rotates together with the horizontal shaft 47, and the barbs on its outer circumference repel the vibration valve 57. As a result, a melody is played from the music box 55. This melody is written by rotors 19 and 20, which will be described later.
When the rotors 19 and 20 are rotating normally, a beautiful melody is produced, and when the rotors 19 and 20 are rotating abnormally (rotating too fast or too slowly), an abnormal sound (a sound that does not resemble music) is produced. Therefore, it is possible to tell whether the rotors 19, 20 are rotating normally, that is, whether the food is being formed correctly, by the sound emitted by the music box.
By adjusting the rotational speed of 20, accurate molding can be performed at all times.

Therefore, in the state shown in FIG. 4 in which the recess 25 of the rotor 19 and the recess 27 of the rotor 20 are separated on the rollers 14 and 15 side, the container 60 is filled with unformed food, that is, cooked rice, and a portion of it is is manually dropped from the food supply hole 61 onto the space between the rollers 14 and 15. When the handle 42 is further turned, the food above the rollers 14 and 15 is forcibly fed between the rollers 14 and 15 by the respective flanges of the rotating rollers 14 and 15, and then by the teeth 18 of the rollers 14 and 15. These rollers 14,1
The food product is forcibly fed onto the extruded sheets 19a, 20a on the recesses 25, 27 of the rotors 19, 20 adjacent to the other side (lower side) of the food molding section 5.
Then, the portions of the extruded sheets 19a, 20a to which the rice has been fed come into contact with the recesses 25, 27, and the other portions of the extruded sheets 19a, 20a are tensioned. Further, as the rotors 19 and 20 rotate, the space between the recesses 25 and 27 is compressed as the recesses 25 and 27 move toward the opposed state, and the recesses 25 and 27 are compressed.
When the pieces 27 face each other as shown in FIG. 5, they are most compressed and formed into a sushi shape. Furthermore, handle 4
When you turn 2, the concave part 25 of the part where the rice is compression molded,
27 is spaced apart on the turntable 52 side, and the recess 2 is immediately above the recesses 25 and 27 where the rice was compression-molded.
Tensioned extruded sheet 19 on 5,27
Rice is supplied from above onto a and 20a. Therefore, the extruded sheet 19 on these recesses 25 and 27
a, 20a are pressed by rice and sag, recessed portions 25, 2
The extruded sheet portions above the recesses 25 and 27, which were in contact with the bottom of the sheet 7 and were previously compression-molded, are suddenly tensed. Therefore, the extruded sheet 19 under the compression-molded rice is suddenly tensed.
The compression-molded nigiri sushi-shaped sushi balls are forcefully pushed out from the recesses 25 and 27 by a and 20a, and the turntable wheel 5 is rotated.
2 falls on top. Therefore, by placing a plate on the turntable 52 and repeating the above operation, the nigiri sushi balls are neatly arranged on the plate in the circumferential direction.
