The present inventor has already developed this type of quantitative dividing mechanism in 1983.
The device described in No. 38175 was proposed, but with this mechanism, the rice may not be divided quantitatively due to insufficient compression of the highly viscous cooked rice, and the dividing plate 4 cuts the raw material while rotating in one direction. In some cases, the separated raw material lumps were not accommodated in the predetermined cylinder hole because of the adhesion of the raw material lumps to the falling direction of the separated raw material lumps.

The present invention was provided in order to eliminate the above-mentioned drawbacks, and its purpose is to provide a forced compression transfer mechanism in a part of the feeding device and a dividing mechanism that simultaneously cuts the discharged raw material from both sides. This is achieved by providing

The shaft pin 52 is also fixed to the lower surface of the bottom plate 21a.

54a and 54b are tension springs interposed between the base ends of the operating rods 51a and 51b and key points on the lower surface of the bottom plate 24a;
Reference numeral 5 designates a solenoid that is fitted and fixed into a notch in the bottom plate 24a, and its core 55a is connected to links 56a and 56b.
It is connected to the operating rods 51a and 51b via.

Thus, the dividing mechanism 5 includes the above-mentioned symbols 5a, 5b and the following 56a.
, 56b, and is operated alternately with the compression transfer mechanism 4 by a control circuit to be described later.

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 seven-acting shaft for supporting and rotating the turntable 6, and is connected to a driving source in the base casing 3.

Inside each molded cylinder hole 61... is a piston 62.
・A running roller 62 is attached to the lower end via the piston rod.
A is provided.

Reference numeral 63 denotes an endless rail-shaped guide path fixed on the casing 3, which periodically moves up and down at a predetermined position 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.

64 is a microswitch fixed on the casing 3;
Reference numeral 65 denotes contacts protruding from the side circumference of the turntable 6 at predetermined intervals, and the microswitch 64 is intermittently opened and closed by rotation of the turntable.

The microswitch 64 is incorporated into the operation control circuit of the drive source section D2 and the solenoid 55, and is provided so that the operation of the drive source section D2 and the solenoid 55 is linked in response to the operation of the turntable 6. It is being

Note that the operation control circuit may include a known power supply circuit and a timer circuit.

In the figure, 25a and 25b are guide plates fixed on both sides of the hora and no discharge ports 21, and 25 is a front plate that covers the raw material passage from the discharge port 21 to the lower end of 41a and 41b to prevent the raw materials from escaping. and the hopper casing 24
is fixed.

Note that by providing a timing circuit in the control circuit without providing the microswitch 64, the drive source section D1. The operating order of D2 and the solenoid 55 may be controlled.

Now, put the raw cooked rice into the hopper 2 and drive the drive source D1.
When the power is turned on, the turntable 6 rotates in the direction of the arrow by the distance between the cylinder holes and stops when the cylinder hole 61a is positioned below the center of the gap between the left and right belts 41a and 41b.

At the stop position of the turntable 6, the contact 65 turns on the microswitch 65, and the power circuit of the drive source section D2 and the solenoid 55 is closed.

Thus, the conveyor belt 23 and the compression belt 41a.

41b is driven once, and cooked rice is discharged into the gap between the compression belts and compressed.

At this time, the cutters 5a and 5b are in a separated state as shown in FIG. collide instantaneously.

Next, the turntable 6 rotates in the m direction again, so
When the microswitch 64 is OFF, the drive source section D2 and the solenoid 55 are deenergized.

Therefore, the operation of conveyor 23 and belts 41a, 41b is stopped.

On the other hand, the cylinder hole 61a moves five times while it is empty, and the subsequent cylinder hole 61b is connected to the left and right belts 41a.

It is located below the center of the gap 41b.

The 7 drive source section D2 and the solenoid 55 operate in the same manner as described above, but in this case, the raw material already waiting in the compression section is pushed downward by the rotation of the belts 41a and 41b in the n direction, and is pushed out into the cylinder. It is housed in the hole 61b.

Next, the solenoid 55 is activated so that the raw material is transferred to the cutter 5.
a and 5b, and is divided into the cylinder hole 61b by the amount accommodated.

Then, the turntable 6 is rotated again and the same operating sequence is repeated.

The divided cooked rice is then transferred by the intermittent rotation of the turntable 6, and in the process, the automatic wasabi setting is done by the mechanism 7, the laying work is done by the mechanism 8, and the automatic pressing is done by the mechanism 8.
After compression finishing, the sushi is completed.

In addition, the intermittent rotation speed of the turntable 6 is at the driving edge D.
The gear transmission mechanism and the intermittent movement mechanism such as a cam in the motor 1 are appropriately combined by known means, or are appropriately adjusted by a control circuit for the electric motor.

According to the quantitative dividing device of the present invention having the above-described structure and operation, the left and right cutters 5a and 5b cut the compressed and discharged raw material from the left and right toward the center, so that the highly viscous raw material is directly cut into 5 pieces. It can be divided at different positions and accommodated appropriately in the cylinder hole 61.

In addition, since the gap between the rotating left and right bells 41a and 41b is shaped like a width downward, the raw material is forcibly conveyed downward while being compressed.

Therefore, the cooked rice stirred by the bars 22a to 22c in the hopper 2 is compressed uniformly, and a fixed amount can always be discharged and supplied downward, so that proper shaping can be achieved in subsequent processes such as wasabi attachment and pressing. It is possible.
