``Technology that comes to i'' Traditional Akebono moss preparation precepts! Fl! ! There are various inventions and ideas for devices and methods for carrying out this invention, and the present applicant has proposed various inventions and obtained the rights to them, and many of them have been put into practical use.

Therefore, representative technical documents or similar technical documents related to the present applicant include the following inventions.

In other words, there is a display panel for controlling the concentration of the seaweed mixture in Japanese Patent Publication No. 60-181675, which displays the concentration of the seaweed mixture produced by mixing the seaweed raw materials and water stored in the stirring tank (concentration adjustment tank). The system detects the concentration, displays this horizontal value, and adjusts the amount of water in the adjustment tank based on this value.

Japanese Patent Publication No. 60-3819 discloses an RFL moss mixture concentration adjustment method and apparatus, in which a seaweed mixture with a higher concentration than the appropriate concentration is supplied to a concentration adjustment tank via a blender, and the concentration is monitored via a concentration sensor. At the same time, it is configured to correct the concentration to an appropriate level only by supplying water.

Japanese Patent Publication No. 62-2709 discloses a method and apparatus for once adjusting a seaweed mixture, in which a seaweed mixture of cut seaweed and water is supplied to a concentration adjustment tank through a blender, and the concentration is monitored through a concentration sensor. At the same time, it is configured to adjust the concentration to an appropriate level by supplying water or draining water.

"Problems to be Solved by the Invention" The inventions in the technical documents mentioned above involve cutting seaweed into the shape of a dragonfly, which is usually produced using a seaweed cutting machine.

, and sent to the seaweed blending machine via the yA blending machine.

When the cut seaweed sent here is sent in fixed quantities to the next processing machine, for example, a concentration adjustment tank, water is simultaneously added to the cut seaweed, where it is roughly adjusted.

This roughly adjusted mixed liquid is conveyed to a concentration correction tank, and is then detected J times via a concentration detection sensor installed between the mixed liquid correction tank, the paper machine, and the mountain. This is a device that maintains and manages the concentration at a set value by directly supplying water or draining water in the liquid preparation tank.

Therefore, a system is created in which auxiliary equipment, such as a blending machine, is placed between the seaweed cutter or ripening machine and the blended liquid compensating tank.

If such a system is adopted, the time required for processing the 5-Kikabara algae will become longer, resulting in a negative impact on the quality of the cut nori.

The most special 18! In the case of lichen algae, if such a situation occurs, the rate of damage to the lichen algae is high;
Ultimately, this will lead to product quality deterioration and price decline in the future, and this distortion in quality will have a negative impact on price.

In addition, each moss is added to the system as a whole. ) is complicated, which also has a negative impact on the quality of cut seaweed, as mentioned above.

In addition, the relatively small work area of the seaweed drying building was filled with seaweed drying equipment, which could impede work and reduce efficiency.

Furthermore, considering the economic aspect of seaweed manufacturing machinery, the prices of this type of machinery and equipment have been increasing recently, and 8! There is a great need for simplification of machinery and equipment.

``Means for Solving the Problems'' Therefore, the present invention aims to simplify the entire system and omit the mechanical equipment (for example, it is desirable to omit the blending machine), as well as to reduce the time required for raw algae processing. In order to significantly shorten processing time, especially in the case of seaweed raw algae, which is the first to be collected, the liquid level of the mixed liquid in the preparation tank is monitored using a floatless sensor. The floatless sensor operates below the set liquid level to supply the cut nori and water, and at the set τα level (double stage), the floatless sensor stops operating and supplies the cut nori and water. supply will be stopped.

In this way, when the liquid level of the mixed liquid is at or above the set liquid level, the concentration of the mixed liquid in this mixed liquid adjustment tank is detected, and the horizontal value deviates from the set range. The water supply/drainage pump is operated via a concentration detection sensor that is activated when the machine is running, thereby controlling the supply and drainage of water to generate a blended liquid and supply this blended liquid to the paper machine.

Further, for the purpose of simplifying and simplifying the mechanical equipment for generating the mixture Iα and achieving reliable operation, the mixture is configured to be generated in a mixture adjustment tank. To this end, in the present invention, cut seaweed and water are directly supplied to a mixing tank Iα in a fixed ratio under the control of a floatless sensor, and the level of the mixed liquid in this mixing tank 7α is set. to keep on saliva,
Also, the mixed liquid maintained at the set liquid level is detected by the a degree detection sensor.

Based on this concentration, H1 controls the supply and discharge of water and/or the supply/stop of cut seaweed in the liquid preparation tank to generate a liquid mixture H1! It is.

In addition, in order to feed only the blended liquid to the paper machine, the present invention uses a feed pump that operates only when the concentration sensor installed in the liquid mixture adjustment tank detects a set value. The feed pump will not operate if the concentration sensor detects a value other than the set value. ), installed between the liquid preparation tank and the stirring tank.

As a result, a configuration was created in which the formulation Iα having a truly appropriate concentration was fed to the stirring tank.

"Function" The present invention will be described in detail below. After the cut seaweed is produced in the seaweed cutter, the cut seaweed is supplied to the liquid preparation tank through an opening (not shown) provided in the seaweed cutter by the operation of a pump. , the structure is such that the pump is supplied via piping that communicates with this closed port, and the pump is turned on and off by a floatless sensor installed in the mixed liquid adjustment tank. It is turned on when it reaches the lower limit, and turned off when it reaches the upper limit.

As a result, a certain amount of cut seaweed is supplied in accordance with the liquid level in the liquid mixture adjustment tank.

On the other hand, in the process of supplying this cut seaweed, a water supply pump installed in the water tank is used to simultaneously supply water and mix it with the cut seaweed to generate a mixed liquid. It is turned on and off by a provided floatless sensor, and specifically, it is turned on when the liquid level of the mixed liquid in the mixed liquid adjustment tank reaches the lower limit, and conversely, it is turned off when it reaches the upper limit.

As a result, the water in the water tank is supplied via the manual valve equipped on the piping facing here in accordance with the liquid level in the mixed liquid adjustment tank, and the amount of water is adjusted according to the Zα surface in the mixed liquid adjustment tank. is supplied.

iL supplied in this way Thoroughly stir and mix the cut seaweed and water through the stirring blade installed here? The concentration of this mixture was adjusted to form a mixture of
The mixed liquid (
Continuously detects the concentration of (prepared liquid).

That is, if the value detected by the concentration detection sensor is higher than the setting 11α, the concentration of the mixed liquid is high, and a signal indicating that the concentration is high is generated from the concentration sensor to the vjl device.

This signal is transmitted to the water tank water supply pump via the control device, and by operating this water supply pump, water from this water tank is supplied to the mixed liquid compensation tank. Therefore, the concentrated liquid mixture in the liquid mixture adjustment tank is diluted and returned to the set concentration.

After that, when the concentration detection sensor detects the set value, the control device issues a stop signal to the water supply pump, and the water supply is stopped.

By continuously controlling the supply or stopping of water from the water tank through the control device and promptly correcting the phenomenon in which the mixed liquid thickens during the nori production process, it is possible to obtain a seaweed mixture with an appropriate concentration. generate.

On the other hand, if the detection f+fi detected by the concentration detection sensor is lower than the set value, the mixed liquid is in a dilute state, and thus a signal indicating that the concentration is dilute is generated from the concentration sensor to the control device.

This signal is transmitted via the control device to the drainage pump of the mixed liquid adjustment tank, and by operating this drainage pump,
Only the water in this mixed liquid adjustment tank is drained into a water tank or the like. Therefore, after two nights of preparation, the dilute mixture in the adjustment tank is diluted to 1 and returned to the set concentration.

After that, when the concentration detection sensor detects the set value, the control device issues a stop signal to the drain pump, which stops draining the water.

By continuously controlling the supply of water from the mixed liquid compensation tank through a concentration sensor and a control device, and promptly correcting the phenomenon in which the mixed liquid deviates from the corrected concentration, the proper concentration can be maintained at all times. Generate +1B moss formulation I bond.

In addition, if the above-mentioned concentration detection sensor is too thin, it is also possible to use a method in which cut seaweed is supplied from a moss cutting machine via a pump.

The liquid mixture produced above is supplied to the paper machine 111 times.

Then, when the liquid level of the mixed liquid in the mixed liquid adjustment tank falls to the lower limit, the floatless sensor is turned on in the same way as described above, and the L-shaped seaweed is lined up (water is supplied, and its li & surface rises. When the upper limit is reached, the floatless sensor is turned off and the supply is stopped.

After that, the concentration of this mixed liquid is detected by a concentration sensor, and the control i! Controlling the supply and discharge of water or the supply and stop of cut seaweed via signals from the machine is the same as in the previous example.

The above-described operations are repeated one after another, and the blended liquid having an appropriate concentration is fed to the paper machine.

In addition, in the above example, it is also possible to install a stirring tank between the blended liquid adjustment tank and the paper machine, and feed only the blended liquid with the proper concentration to the paper machine through this stirring tank. It is.

In the figure, 20 is a control device, and 21 is a water pump provided in this water tank 10. Then, it is returned to this picture word mixture adjustment tank 20.

The concentration detection sensor 30 can also be installed in other devices! For example, it can also be installed inside the liquid preparation tank 22. Further, the detection method and control means may be an ultrasonic method.

The example shown in FIG. 2 is a device that feeds only the finely adjusted mixture produced in the mixture adjustment tank 22 to the stirring tank 40.

"Effects of the Invention" As described in detail above, the present invention involves supplying and mixing cut seaweed and water from an aquarium directly to a mixed liquid compensation tank, and monitoring the liquid level of this mixed liquid with a floatless sensor. The concentration of the mixed liquid that maintains this set liquid level is detected by a concentration detection sensor, and based on this detected value, the supply and discharge of water in the mixed liquid correction side is controlled to adjust the mixed liquid. Since this is a device that adjusts the seaweed mixture to yA through so-called cut seaweed and water supply/stop means and a control means that detects and controls the concentration of the set liquid level, as a general rule, mixing 1 is performed in the mixture adjustment tank.
