Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to food products, particularly food products molded using boiled rice as a main material,
For example, the pressing of raw materials in an apparatus for mechanically and continuously automatically forming manually formed foods such as sushi and rice balls is related to an apparatus.

This type of presser foot mechanism was already developed by the inventor in 1983.
-38175 was proposed, but this mechanism presses the raw material from above and below while the turntable is rotating, that is, while transferring the material, so the mechanism also requires a rotating part to press down. It has disadvantages such as the sushi type is complicated, the sushi type etc. may deviate, and the presser foot is difficult to adjust the pressure.

The present invention was provided in order to eliminate the above-mentioned drawbacks, and its purpose is to provide a turntable in which a plurality of molded cylinder holes are arranged in a circle, and a turntable that is loosely inserted into each of the cylinder holes. A piston, a piston guide mechanism for imparting a predetermined sliding cycle to the piston during one rotation of the turntable, a presser device for compression molding raw materials, and a piston for horizontally moving the turntable intermittently. The pressing device of an automatic food molding machine having a rotating drive mechanism includes a pushing mechanism for temporarily pushing up and separating the piston from the guide mechanism, and a pushing mechanism for pushing the raw material from above in correspondence with the pushing mechanism. a pressing mechanism for temporarily pressing;
Presser clamping in an automatic food molding machine is achieved by an apparatus comprising an intermittent actuation mechanism for synchronously operating the push-up mechanism and the press mechanism when the turntable stops rotating;

The invention will now be explained in more detail according to the embodiments shown in the drawings.

FIG. 1 shows a sushi molding machine 1 as an embodiment of the automatic food molding machine according to the present invention.

2 is a raw material input hopper, 3 is a base casing, 4 is a compression transfer mechanism, and 5a, 5b are cutters for quantitative division.

Reference numeral 6 denotes a turntable having a plurality of forming cylinder holes 61 arranged and opened in a substantially circular manner, and receives the raw material from the dividing mechanism 5 and repeats sequential forming and discharging while rotating.

S is a drive shaft for supporting and rotating the turntable 6, and is connected to a drive source D1 inside the base casing 3.

A piston 62 is slidably inserted into each molded cylinder hole 61 (Fig. 2).
... has a running roller 6 at the lower end via the piston land.
2a is provided.

Reference numeral 63 denotes an endless rail-shaped guide path 1 fixed on the casing 3, which periodically moves up and down at predetermined positions when the traveling rollers 62a... travel in a circular manner as the turntable 6 rotates. It is formed in an endless shape with height differences to guide the user through the process.

3 and 4 show a pressing mechanism 8 according to the present invention.

Reference numeral 81 denotes a drive rod, which is fixed to the base casing 3 so as to be movable up and down, and connected to the drive source section D1 via the intermittent actuation mechanism D3.

82 is a connecting arm fixed to the drive rod 81, a part of which protrudes above the turntable 6 and connects the suppressing mechanism 8.
3 is supported and fixed.

The pressing mechanism 83 consists of a connecting rod 83a and a pressing member 83b fixed to the lower end of the connecting rod 83a, and is arranged so that the pressing member 83b faces the cylinder hole 61.

Reference numeral 84 denotes a push-up mechanism, which includes a swing plate 841 rotatably provided around a shaft pin 842, a support member 843 fixed on the base 3 to support the shaft pin 842, and a push rod. It consists of 85.

Thus, one end 841a of the swing plate 841 is connected to the guide path 6.
3 and forms a part of the guide path.

Reference numeral 63a designates a recessed portion formed by cutting out a part of the road surface of the guideway into which the end portion 841a of the rocking plate can be inserted.

Under normal conditions, the roller 62a at the lower part of the piston is arranged so that the guide road surface and the upper surface of the rocking plate end 841a are connected substantially smoothly.
It is assumed that the vehicle can run smoothly.

Note that one end 841a of the rocking plate is located directly below the pressing member 83b.

The push rod 85 is fixed at a key point on the connecting arm 82, and its lower end is arranged to face the upper surface of the swing plate 841 near the other end.

Now, the turntable 6 is rotated and the cylinder hole 61 is in the third position.
When the piston reaches the position shown in the figure, the roller 62a below the piston is located on the upper surface of the end 841a of the rocking plate.

Here, by driving the first drive rod 81 downward, the cooked rice or cooked rice in the cylinder hole 61 and the sushi seeds placed on it are simultaneously compressed from above and below into a predetermined shape and hardness. It is molded.

That is, as shown in FIG.
1 or slightly into the opening to press down the raw material from above, while the push rod 85 descends via the connecting arm 82 and rotates the rocking plate.

As a result, the swinging plate 841a rises in the direction of arrow l and pushes up the piston 62, so that the raw material in the cylinder hole 61 is compressed and compressed by the pressing member 83b and the piston 62.

In order to make this compression force adjustable, the connecting rod 83a is attached to the connecting arm 82 so that its length can be adjusted, or the push rod 85 is attached to the connecting arm 82 so that its length can be adjusted, or the push rod 85 is attached to the connecting arm 82 so that its length can be adjusted. Alternatively, the swing plate 841 may be pressed by an elastic coil spring (not shown), or these may be blocked.

Next, when the drive rod 81 is raised, the presser member 83
b is pulled up and away from the cylinder hole 61, and at the same time the pusher 85 is also pulled up and away from the swinging rod 841, returning to the position shown in FIG. 3.

Thus, the piston D roller 62a also returns to the guide path 63.

Next, the turntable 6 rotates in the direction of arrow m, and the subsequent D
After the cylinder hole 61 is moved directly below the holding member 83b and stopped, the drive rod 81 is operated again to perform the compression molding process, and the same operation is repeated.

Therefore, the intermittent rotation operation of the turntable 6 and the drive rod 81
The order and timing of the upper and lower intermittent operations are determined by the drive source section D1.
Alternatively, a mechanical interlocking mechanism in the intermittent operating mechanism D3 or separate electric motors may be provided for the drive source section D1 and the operating mechanism D3, and these may be controlled by an electrical control circuit.

Also, while the turntable 6 is stopped and the presser mechanism 8 is operating, the other cylinder holes 61a) or the first and second
As shown in the figure, it is located between the cutters 5a and sb of the dividing mechanism 5, and is supplied with cooked rice from the upper raw material supply mechanism 4, and undergoes a step of receiving a fixed amount of rice by the cutters 5a and 5b.

Thus, rotational urging of the belt drive roller R in the supply mechanism 4 and cutters 5a and 5b in the dividing mechanism 5 are performed.
It is also assumed that the order and timing of energization of the turntable are controlled by the electric control circuit of the first drive source section D1 of the turntable, the drive source section D3 of the supply mechanism, and the treid 55.

According to the present invention having the above-described structure and operation, the compression molding process during finishing is performed while the turntable is stopped, so the surface of the raw material does not collapse, and the sushi balls placed on the raw material do not collapse. No deviation or deviation occurs.

Furthermore, since the pressing force can be easily adjusted, it is possible to finish the material with an arbitrary and appropriate hardness depending on the quality of the raw material.

In addition, the vertical movement of the piston in the process of taking out the finished product after finishing and resupplying raw materials is according to the above-mentioned Japanese Patent Publication No. 56-38.
Of course, the known technique disclosed in No. 175 may be used.
