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 present invention relates to an additive supply device in an apparatus for automatically and continuously mechanically forming foods that are basically manually formed, such as sushi rolls and rice balls.

The present inventor has already developed this type of automatic molding machine in 1983.
The method described in No. 38175 was proposed, but when forming sushi using this mechanism, the work of adding anti-stick additives such as wasabi must be done manually after feeding raw materials to the cylinder hole and during removal of the finished product. had to be done.

The present invention aims at saving labor by allowing the supply of such additives to be carried out continuously as a step in the automatic molding process.

Another object of the present invention is to provide an additive supply system that can be operated in response to the movement speed and timing of the main material.

Still another object of the present invention is to provide an additive supply device that allows adjustment of the amount of additives supplied.

The object of the present invention is to provide an automatic food molding machine having a molding member provided rotatably or reciprocally, and a first drive mechanism for intermittently driving the molding member. an additive discharge section disposed above; a pressure feeding mechanism connected to the discharge section via a supply pipe; a support member that supports at least the discharge member and is movable up and down; a second drive mechanism for intermittently moving the member up and down; an automatic food molding machine configured to supply additives by a pressure feeding mechanism when the discharge part descends near the upper surface of the molded member; This is achieved by the additive supply device at.

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

1 and 2 show a sushi molding machine 1 as an embodiment of an automatic food molding machine to which the present invention is applied.

Reference numeral 2 denotes a raw material input hopper, which is fixed to the base casing 3 and whose discharge port 21 opens above the compression transfer mechanism 4.

23 is a conveyor belt for transferring the raw cooked rice in the hopper to the outside of the discharge port 21.

41a and 41b are a pair of left and right endless belts facing each other so as to be rotatable in the vertical direction, and constitute a main material transfer mechanism 4 driven and guided by rollers R and r.

5a and 5b are cutters in the quantitative dividing mechanism 5, which are operated intermittently by a solenoid 55.

6 is a turntable which is a molding member, and a first driving source D
1, it is intermittently rotated in the direction of arrow m.

Reference numeral 61 designates a plurality of molded cylinder holes arranged and opened in a substantially circular manner along the periphery of the turntable 6, into which pistons 62 are loosely inserted.

Reference numeral 81 is a drive rod that is intermittently moved up and down by the third drive source section D2, and moves the connecting arm 82 up and down.

A presser mechanism 8 is fixed to key points of the arm 82, and an additive supply device 7 according to the present invention is connected thereto.

The supply device 7 includes at least an additive discharge section 71 disposed above the drive locus of the cylinder hole 61, a pressure feeding mechanism 72 connected to the discharge section 71 via a supply pipe 73a, and an additive discharge section 71 disposed above the driving locus of the cylinder hole 61; It has support members 74 and 75 for fixing the discharge part 71 and the pumping mechanism 72 to the connecting arm 82, respectively.

FIG. 3 shows an example of the configuration of the present supply device 7, in which a discharge member 71 is fixed to a support member 74 via a vertically adjustable Ron door 4a, and its lower surface has the shape of the upper opening of the cylinder 61. It has a contact surface 71a that is substantially the same as that of
A supply pipe 73a is connected to the discharge passage 71b that opens to the contact surface 71a.
One end is fixed in communication.

Reference numeral 72a designates an intermittent pressure-feeding cylinder that is fixed or detachably fixed to the connecting arm 82 via a support member 75, into which a piston 72b is loosely inserted, and a piston door 2c protrudes downwardly from the outside. There is.

Reference numeral 72c denotes an abutment member screwed and fixed to the base casing 3 directly below the piston door 2c, and the height can be adjusted by adjusting the weight of the screw.

The supply pipe 7 is disposed on the upper surface of the intermittent pressure feeding cylinder 72a.
The other end of supply pipe 73b is fixed and communicated with, and one end of supply pipe 73b is fixed and communicated with at a proper position on the outer periphery.

Reference numeral 76 is a constant pressure feeding section, 76a is a replenishment cylinder, and the other end of the supply pipe 73b is fixedly connected to the lower part of the cylinder.

Reference numeral 76b denotes a weighted piston that is detachably inserted loosely into the cylinder 76a, and is provided so that its weight always presses out the additive filled in the cylinder 76a into the supply pipe 73b.

Now, in FIG. 1, after the cylinder hole 61a moves directly below the discharge part 71 and stops, when the five drive rod 81 descends, the connecting arm 82 also descends.

Therefore, the discharge member 11 and the pressure feeding mechanism 72 are simultaneously lowered in the direction of the arrow 1, and the contact surface 71a of the discharge member 11 is at a position near the opening surface of the cylinder hole 61 or slightly inside the opening, and the raw cooked rice is removed. Opposite the top surface.

At this time, the piston rod 72c in the intermittent pressure-feeding cylinder 72a collides with the contact member 72 (1/lc), causing the piston 7
2b, the additive in the cylinder 72a, such as kneaded wasabi, is discharged onto the cooked rice from the outlet of the discharge passage 71b via the supply pipe 73a.

Note that when the piston 72b presses, the supply pipe 73b
However, by increasing the weight of the weight piston 76a in the supply cylinder 7'6a, backflow of the additive is prevented.

Of course, a check valve 72e may be provided on the inner wall of the cylinder 72a to prevent backflow.

Next, the drive rod 81 is raised, the discharge part 71 is separated from the turntable 6, and the intermittent pressure feeding mechanism 72 is also moved upward, completing the discharge addition operation.

Next, the turntable 6 rotates to open the subsequent cylinder hole 6.
1 is positioned directly below the discharge portion 71 and stops, the above-described discharge addition operation is repeated again.

In this case, the height position of the contact surface 71a of the discharge portion may be adjusted by the screwing amount of the Ron door 4a, so that the amount of entry into the cylinder hole 61 can be adjusted.

Further, the height of the contact member 72d may be similarly adjusted to adjust the stroke width of the piston 72b, thereby adjusting the discharge amount of the additive.

The speed and timing of the intermittent rotation of the turntable 6 and the vertical movement speed and timing of the drive rod 81 are controlled in conjunction with each other by the mechanical intermittent transmission mechanism or electrical control circuit of the drive source sections D1 and D3. The above-mentioned operations of the material supply device are also automatically linked.

Although the turntable 6 having the cylinder hole 61 is illustrated as a molded member, the present invention is not limited to this, and the discharge part 71
The structure includes an endless belt conveyor, a reciprocating plate, etc., on which the raw materials are placed directly below and passed intermittently. Of course, it is also possible to make them interlock according to the above.
