Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supply device for supplying a predetermined amount of rice cake raw material to a rice cake making machine widely used in the food processing industry such as confectionery rice cakes.

[0002]

2. Description of the Related Art There are various types of rice cake punching machines known, but basically they are composed of a pestle and a mortar body, and in order to obtain a desired rice cake, a predetermined amount of rice cake raw material in the mortar body is used. Predetermined time (predetermined number of times)
It is necessary to punch, and the supply of the rice cake raw material in the automation of the rice cake making machine must be performed properly and continuously.

Therefore, the applicant of the present invention has previously provided an extruding section for extruding the dough material from the extruding opening and a supply mechanism having an opening / closing section at the extruding opening, and a receiver and a receiver arranged below the extruding opening. A rice cake raw material supply device composed of a weighing mechanism having a placed weighing unit has been proposed (Japanese Patent Laid-Open No. 3-292867).
issue).

[0004]

The feeding mechanism pushes the rice cake raw material (kneaded material) from the extrusion port, drops it into the receiver, and closes the extrusion port when the metering unit detects the supply of a predetermined amount. As a result, a fixed amount of supply is realized.

However, when the above means is adopted, a measurement error is likely to occur. That is, immediately after closing the extrusion port, not all the rice cake raw materials to be supplied are stored in the receiver and the weight is not measured, but the rice cake raw material in the middle of falling between the extrusion outlet and the receiver is measured. Not not. Of course, it is natural to set the amount of rice cake raw material in the middle of dropping in advance to the set weight of the operation of the opening / closing part, but the weight of rice cake raw material in the middle of falling is the moisture content, However, the weight does not always come as expected, because it is greatly affected by the air content, adhesiveness, etc. Therefore, the present invention proposes a rice cake raw material supply device in which the error in the supplied weight is reduced.

[0006]

A device for feeding a rice cake raw material according to the present invention comprises an upper large extrusion port and an extruding section for extruding the kneaded rice cake raw material from a lower small extrusion port continuous below the large extrusion port. At the same time, the opening / closing part having the function of fully opening / closing the extrusion port and the opening / closing operation of only the small extrusion port, the feeding mechanism provided in the extrusion port, the receiver and the receiver arranged below the extrusion port are mounted. It is characterized by comprising a weighing mechanism including the above-mentioned weighing unit.

Further, particularly in the rice cake raw material supply device described above,
It is characterized in that the rice cake raw material is extruded to the receiver with the opening / closing part fully open, and when the extrusion amount approaches the set value, the opening / closing part is operated only for the small extrusion port. .

[0008]

When steamed rice is supplied to the extruding section, the rice cake material is kneaded into a kneaded state and is extruded from the extruding port and dropped into the receiving unit. The metering unit measures the weight of the rice cake raw material supplied, and when it approaches the preset amount, the opening / closing unit is operated to switch the supply from the small extrusion port, and when the set amount is reached, the extrusion port is fully closed. To do.

EXAMPLES Next, examples of the present invention will be described. The rice cake raw material supply device includes a supply mechanism and a measuring mechanism, and the supply mechanism includes an extrusion unit 1 and an opening / closing unit 2. The extrusion unit 1 includes a hopper 11 and an extrusion cylinder 12 arranged below the hopper 11.
And a screw bar 13 installed in the extrusion cylinder 12 and an extrusion port 14 provided at the tip of the extrusion cylinder 12. In particular, the extrusion port 14 is a large extrusion port 14A on the upper side and a small extrusion port on the lower side continuous with the large extrusion port 14A. It consists of the exit 14B.

The opening / closing part 2 is a lid 2 for opening / closing the extrusion port 14.
1 and a cylinder 22 that drives the lid 21,
The cylinder 22 is controlled by a signal from a measuring unit described later.

The metering mechanism is composed of a receiver 3, a receiver driving unit 4 and a measuring unit 5. The receiver 3 is formed in a bowl shape and is arranged below the above-mentioned extrusion port 14, and the center of the bottom part thereof is provided. And an outer receiver portion 32 which is a peripheral surface portion of the bowl-shaped container.
An opening / closing door 33 is provided on a part of the peripheral surface thereof, and an appropriate opening / closing member 34 is attached to the opening / closing door 33, and a guide plate connected to the mortar a of the rice cake machine is provided at a portion opened by the opening / closing door 33. Further, the receiver driving unit 4 has a motor built therein and drives the inner receiver unit 31 to rotate.

The weighing unit 5 mounts the receiver 3 and the receiver driving unit 4, measures the weight change of these, and controls the opening / closing operation of the cylinder 22 of the opening / closing unit 2 and the opening / closing member 34 of the receiver 3. It emits a signal.

The control method is as follows: When the weight change (the amount of rice cake raw material supplied) measured by the measuring unit 5 reaches a value close to a preset desired amount, the lid 21 is semi-closed (large extrusion port 14A). Closed), and the lid 21 is intermittently opened and closed until the desired amount is reached.

When steamed rice is fed from the hopper 11, the steamed rice is advanced to the extrusion port 14 side in the extrusion cylinder 12 by the screw bar 13, and in the course of this process the steamed rice is crushed into a kneaded state and extruded from the extrusion port 14. It is extruded and supplied to the receiver 3 (see FIG. 4).

In the weighing unit 5, when the predetermined weight change, that is, the set value is approached, the cylinder 22 of the opening / closing unit 2 is operated,
The large extrusion port 14A is closed with the lid 21, and then the lid 21 is closed.
Is operated intermittently under the following predetermined control. That is, the rice cake raw material is supplied to the receiver 3 as a small lump by intermittently opening and closing the small extrusion port 14B. In particular, the weight is measured each time a small lump of the rice cake raw material is supplied. Is performed until the set value is reached (see FIG. 5). Therefore, the error of the supply amount is at least less than this small amount.

Further, since the inner receiver portion 31 of the receiver 3 is rotating, the kneaded rice cake raw material is lumped as it rolls on the inner peripheral surface of the outer receiver portion 32 and is supplied to the rice cake whisk a. It is what is done.

The present invention is not limited to the above-mentioned embodiment, and the present invention is such that at least the extrusion ports are continuously formed in large and small sizes, and the small extrusion ports are used when the supply amount of the rice cake raw material approaches the set value. Anything can be supplied as long as it is extruded and supplied, and even if it is a continuous opening regardless of the intermittent operation of the opening / closing part, the amount of rice cake raw material is small during the fall immediately after the opening / closing part is fully closed, so the error in supply amount can be reduced. Is. Further, any receiving container can be adopted.
