Abstract

PURPOSE:To make it possible to carry out the concentration control stably with a high accuracy, by draining or hydrating a laver according to the concentration at a given level with a level and a concentration sensors provided in a laver preparing tank. CONSTITUTION:A laver fed from a laver feeding mechanism 1 and water from a pump 3 are fed to a preparing tank 2 and stirred by a stirring mechanism 5. If a water level sensor 4 senses a level (H), the concentration is measured by a concentration sensor 6, and the measured values are compared with a set value by a controller 13. In the case of the low concentration, water is discharged from the tank 2 by a draining mechanism 8. If the concentration is high, the laver is hydrated by a hydrating mechanism 7. If the concentration is a proper value, the laver is fed to a storage tank 9 by a pump motor 12 and then fed to a laver sheet forming machine. If the level in the preparing tank 2 is lowered, the laver and water are fed again to carry out the preparation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seaweed blending device, and particularly to a seaweed blending device that is capable of stable concentration control.

Conventional seaweed blending equipment feeds the blended liquid while controlling the blended concentration; in other words, water is added when the concentration is high, and water is drained when the concentration is low, so even if it deviates from the set value midway through, it is output as is. As a result, there were many variations in the accuracy of the concentration.Also, the distribution of seaweed during stirring differs depending on the water level in the mixing tank, so it is difficult to determine what to measure depending on the location of the concentration sensor. Because water was being added and drained repeatedly without knowing whether the concentration was being mixed or not, it was not possible to improve the accuracy of concentration measurements.

In view of the above, the present invention detects the concentration at a constant water level in the mixing tank, and so that the concentration always reaches the set value, the water is removed by the drainage mechanism when it is low, and the water is added by the water addition mechanism when it is high, so that the concentration always reaches the set value. The object of the present invention is to provide a seaweed blending device that can reliably control the concentration by sending a blended liquid when the seaweed is mixed.

The main point of the present invention is that the constant water level (H level) t of the mixing tank
When the mixed liquid arrives, the concentration of the liquid in the mixing tank should be stable from the point in time, and since the concentration is always determined by stirring at a constant water level, the measurement conditions are the same. For this reason, the seaweed blending device is designed to produce highly accurate products.

It is equipped with a level detection sensor that detects the L level and H level of the blended solution in the blending tank, a concentration sensor for the blended solution, and a mechanism that stirs the water and seaweed in the blending tank. In a seaweed blending device equipped with a controller that controls a water addition mechanism and a drainage mechanism in conjunction with a signal, the concentration of the seaweed and water mixture at a constant water level is detected, and the concentration and set value are The seaweed mixing device is configured to adjust the amount of water based on the difference in the amount of water.

.

Further, 14 is a first memory circuit, and 15 is a second memory circuit.

According to this embodiment, concentration control is started when the water level of the mixing tank 2 is at the H level, and the mixed liquid is sent out when the set value is reached.

That is, a seaweed supply mechanism l that supplies cut seaweed,
A mixing tank 2, a pump 3 that pours seaweed into the mixing tank 2, and the L level and H level of the mixing liquid level in the mixing tank 2.

and pump 3. Water adding mechanism 7. In the configuration shown in FIG. 1, which includes a controller 13 for ON-OFF control of a pump associated with a drainage mechanism 8 and a pump motor 12, a first memory circuit 14. A configuration including a second memory circuit 15 is added.

In the case shown in FIG. 2, the second storage circuit 15 is set using the concentration OK double signal and the H level detection output of the level detection sensor 4 via the first storage circuit 14 to detect the level. The L level unattained signal from the sensor 4 causes the first. The second memory circuit 14, 15 is reset, and the ON-OFF control of the pump motor 12 is performed in relation to the output of the second memory circuit 15.

Next, the operation of the apparatus having the above configuration will be explained.

First, the seaweed supplied from the seaweed supply mechanism l and the pump 3
The water from is poured into the mixing tank 2 and stirred.

Note that the amounts of seaweed and water to be added at this time are fixed. ``Then, when the above-described liquid mixture reaches the H level, which is a constant water level in the illustrated mixing tank 2, the concentration is measured by the concentration sensor 6, and compared at the controller 13 to see if it has reached the set value.

In this comparison, if the water is thin, water is removed by the drainage mechanism 8, if it is thick, water is added by the water addition mechanism 7, and if the density is OK, the water is left as is.

Thereafter, as shown in FIG. 2, the concentration OK double signal indicating that the set value has been reached and the H level signal related to the constant water level in the mixing tank 2 via the storage circuit 14 are ANDed, that is, both conditions are satisfied. After confirming that this has been established, the second memory circuit 15 is operated, and the output of this second memory circuit 15 is
This is to drive the pump motor 12 when a condition is met, that is, to prepare for subsequent operations.

In other words, the pump motor 12 is driven only when the water level is at the H level and the concentration is OK. At that time, if the conventional operating condition K described later is ON, it is turned ON, and if it is OFF, it is turned OFF. Become.

Note that when the pump motor 12 starts to drive, the mixing tank 2
Even if the water level of the first memory circuit 14 falls below the H level,
Since the output of 9 does not change, the mixed liquid continues to be fed.

When the water level of the mixing tank 2 becomes lower than the L level shown in the figure, the first storage circuit 14 and the second storage circuit 15 are reset by the L level unattained signal from the level detection sensor 4. This is to stop the pump motor 12.

During this time, the blended liquid corresponding to the amount between the L level and the H level of the blending tank 2 was sent out.

In addition, to explain the conventional operating condition K mentioned earlier, the Bongumoori 12 has conventionally been operated under the conditions of the temporary storage tank 9.
OFF at H level of overflow prevention level detection sensor 10
At F, there is no ONL unless it is sucked into a separate plow machine side (not shown) and becomes below the L level, but in this embodiment, the ON condition of the conventional operation and the second memory circuit 15 The above-mentioned temporary storage tank 9 is used for operation during the continuous seaweed production process. It is something that can be given.

And control these controls? Drop with shishidamono as you did in 13.

According to the invention according to this embodiment, the following effects can be expected in summary.

(1) Concentration detection accuracy is high because the stirring state of the blended liquid in the blender is always the same, i.e., at a constant water level.

(2) Only the mixed liquid with an acceptable concentration is sent, so the seaweed is uniformly finished.

Next, FIGS. 3 and 4 are related to other embodiments, FIG. 3 is a control configuration circuit diagram added to the configuration related to FIG. 1 mentioned earlier, and FIG. FIG. 3 is an input/output signal diagram of the static conversion device.

In the figure, 16 is a concentration signal A/D conversion circuit, 17 is a storage device, 18 is a static conversion device, 19 is a water metering tank with a level detection sensor, and 20 is a waste water metering tank also with a level detection sensor. It is. Then, the above A/D conversion circuit 16. Storage device 17. The static conversion device 18 etc.
Controller 1 containing the main components shown in Figure 2 above
3 is placed in the controller 13A of FIG. 1,
It is meant to be controlled.

In addition, both water addition and drainage measuring tank 19.20 are:
It supplies and discharges a specified amount according to the input setting value.
It is equipped with a 3-step level detection sensor that performs this for each step, and makes fine adjustments to water addition and drainage. is to be left empty.

Therefore, the device according to this embodiment detects the concentration of the seaweed and water mixture in the mixing tank 2 when it reaches the H level, and adds water by an amount corresponding to the difference between the concentration and the set value.
The system is designed to pump out the liquid mixture while draining water.

Sunawachi, level detection sensor 4 detects H level,
The concentration is measured when the pump associated with the pump motor 12 starts operating, and an amount of water proportional to the difference from the set value is added from the water metering tank 19 if the concentration is high, or from the drainage metering tank 20 if the concentration is low. Alternatively, by sending the mixed liquid to the temporary storage tank 9 while draining water, reliable concentration control is performed. a concentration signal A/D conversion circuit 16, a storage device 17, a static conversion device 18, and a water metering tank 19 with a level detection sensor.
and a drainage measuring tank 20 equipped with a level detection sensor.

In the system shown in FIG. 3, the water addition measuring tank 1
While supplying or draining a specified amount of water from 9 or the drainage measuring tank 20, the pump associated with the pump motor 12 is operated until the L level of the mixing tank 2 is detected to send the mixed liquid to the temporary storage tank 9. It is composed of

Next, the operation of the apparatus having the above configuration will be explained.

That is, in the present embodiment, when the level of the mixing tank 2 into which seaweed and water are thrown is below the H level, the controller 13A turns on the seaweed supply mechanism 1 and the pump 3, and still When the H level is detected, it is turned off, and at the same time, the pump motor 12 is turned on and the mixed liquid is sent to the temporary storage tank 9.

As a result, the level of the mixing tank 2 decreases, and when the level detection sensor 4 detects the L level, the controller 13A turns on the seaweed supply mechanism 1 and the pump 3 again.
The pump motor 12 is set to 0FFL, and the sending of the mixed liquid to the temporary storage tank 9 is stopped.

Now, when the level detection sensor 4 detects the H level and turns on the pump motor 12, the concentration will be lower than the set value concentration.
If there is a deviation, the added control circuit shown in FIG. 3 will cause the specified amount of water to be pumped from the water addition metering tank 19 through the water addition mechanism 7 if it is thick, or through the drainage mechanism 8 to the drainage metering tank 20 if it is thin. The liquid mixture is sent to the temporary storage tank 9 while adding water or draining water.

Then, by repeating the above-described operations, the liquid mixture having an appropriate concentration is sent to the temporary storage tank 9.

Water measuring tank 19 in the above. Drainage metering tank 2
The control operation of 0 will now be explained with reference to FIG.

The A/D conversion circuit 16 converts the analog value of the difference between the concentration setting value and the measured value into a digital value, ANDs it with the H level signal of the level detection sensor 4, and then stores it in the storage device 17.
Set (S). Also, the L of level detection sensor 4
The level signal is used to reset the storage device 17 to 1-(FL).

As a result, the digital values output from the storage devices 17OFFI to FF8 become the concentration when the level of the mixing tank 2 is H, and are held until the level detection sensor 4 detects the L level.

The static converter 18 stores A-H from the storage device 17 mentioned above.
The output value to the water measuring tank 19. Drainage metering tank 2
Level detection sensor attached to 0 (Ll~L3.Ml~
M3) is converted into a value corresponding to the output of M3), and a signal for driving the water adding mechanism 7 or the draining mechanism 8 is output until the values match.

The water addition measuring tank 19 measures the amount of water added by the water addition mechanism 7 using its level detection sensor.

Further, the drainage measuring tank 20 measures the amount of water drained by the drainage mechanism 8 using its level detection sensor.

If the currently measured concentration is higher than the set value, for example,
When the concentration is "2", the static conversion device 18 makes the + (plus) output high level until the output value of the level detection sensor of the water metering tank 19 becomes equal to the value converted into the input concentration difference signal. to drive the water adding mechanism 7. This is illustrated by the correspondence between column H and column G in FIG.

As a result, when the concentration is high, the mixed liquid is sent to the temporary storage tank 9 while adding water in an amount corresponding to the difference from the set value, and the concentration is controlled to the same value as the set value.

On the other hand, when it is thin, for example, when it is thin by @1'', the static converter 18 converts - until the output value of the level detection sensor of the wastewater measuring tank 20 becomes equal to the value obtained by converting the input concentration difference signal. The (minus) output is set to high level and the drainage mechanism 8 is driven.This is shown in the correspondence of column C to column 2 in FIG.

As a result, if the mixture is thin, the mixture is sent to the temporary storage tank 9 while removing an amount of water corresponding to the difference from the set value, and the concentration is controlled to the same value as the set value.

As described above, according to this embodiment, the concentration of the liquid mixture sent to the temporary storage tank 9 is reliably controlled and the concentration is always constant.

In this way, the quality of the seaweed can be improved because it is possible to always send the mixed liquid at a constant concentration to the storage tank, etc., and as in the previous example, the concentration can be kept equal to the set value. The liquid mixture is not sent after such control, but is sent from the time when the H level is detected, so there is no need to wait for the time required for control, and efficiency can be improved.

Next, FIGS. 5 and 6 relate to still other embodiments, and as before, FIG. 5 is a control circuit diagram added to the configuration in FIG. 1, and FIG. 6 is a control circuit diagram added to the configuration in FIG. , is an input/output signal diagram of the static conversion device.

In the figure, 16 is a concentration signal A/D conversion circuit, 17 is a storage device, 21 is a static conversion device, and 22 is a timer.

The A/D conversion circuit 16.storage device 17. Static conversion device 21. The timer 22 and the like are installed in the controllers 13 and 13, which house the main components shown in Figures 2 and 3 of Sagi.
It is stored in the controller 13B of FIG. 1 in place of A,
It is something that is meant to be controlled.

According to this embodiment, the concentration of the seaweed and water mixture in the mixing tank 2 is detected when it reaches the H level, and water is added and drained for a time corresponding to the difference between the concentration and the set value. The liquid mixture is sent out while the process is being carried out.

In other words, the level detection sensor 4 detects the H level,
The concentration is measured when the pump motor 12 starts operating, and the mixed liquid is temporarily stored for a time proportional to the difference from the set value, while driving the water addition mechanism 7 if the concentration is high, and the drainage mechanism 8 if the concentration is low. By sending the signal to the tank 9, reliable concentration control is performed, and in addition to the configuration shown in FIG.
/D conversion circuit 16, storage device 17, and static conversion device 2
1 and a timer 22.

What is shown in Fig. 5 is the H of the previous mixing tank 2.
When the level is detected, the seaweed supply mechanism 1 and pump 3 are turned off, and until the L level of the mixing tank 2 is detected, water is added or drained for a specified period of time depending on the difference between the detected concentration at the H level and the set concentration, and the mixture is mixed. It is configured to send the liquid to a temporary storage tank 9.

That is, in this embodiment, the third
Similarly to the embodiment shown in the figure, when the level of the mixing tank 20 is below the H level, the controller 13B turns the seaweed supply mechanism 1 and the pump 3 ONL, and when the H level is detected, the controller 13B
At the same time, the pump motor 12 is turned on to send the mixed liquid to the temporary storage tank 9.

As a result, the level in the mixing tank 2 decreases, and when the level detection sensor 4 detects the L level, the controller 13B turns the seaweed supply mechanism 1 and pump 3 ONL again, sets the pump motor 12 to 0FFL, and temporarily stores the mixed liquid. /ri9
This will stop sending to.

Now, when the level detection sensor 4 detects the H level and turns on the pump motor 12, if the concentration deviates from the set value, the added control circuit shown in FIG. If the liquid is thin, the drainage mechanism 8 is configured to send the mixed liquid to a temporary storage tank 9 for a specified period of time.

Then, by repeating the above-described operations, the liquid mixture having an appropriate concentration is sent to the temporary storage tank 9.

Water adding mechanism 7 in the above. The operation of the drainage mechanism 8 is
．． This will be explained next with reference to FIG.

The A/D conversion circuit 16 converts the analog value of the difference between the concentration setting value and the measured value into a digital value, ANDs it with the H level signal of the level detection sensor 4, and then stores it in the storage device 17.
is input, and this storage device 17 is set. Further, the L level signal from the level detection sensor 4 is used to reset the storage device 17.

As a result, the digital value output from the storage device 17 is
The concentration difference becomes the concentration difference when the mixing tank 20 level is H level, and is held until the level detection sensor 4 detects the L level.

The static conversion device 21 converts the output value of the storage device 17 into the setting signal of the timer 22 and the water addition mechanism 7. It converts into a code signal that drives the drainage mechanism 8 and outputs a code output.

The timer 22 turns on the output for a time specified by the output value of the static conversion device 21.

After being ANDed with the aforementioned code signal, the water adding mechanism 7 or the draining mechanism 8 is driven.

Now, when the measured concentration is 9'', 2'' larger than the set value, that is, when the concentration difference signal in the G column is 2'' larger than the E column in FIG.
The output value of the static conversion device 21 is fi 2n1 sign output is +
(plus), and the signals output from the static conversion device 21 are at the level . . . the signal to the 2nd terminal of the timer 22 in FIG. 5 and the signal to the 10th terminal.

The timer 22 outputs Q for the time corresponding to '2#.
is set to a high level, and the output Q of this timer 22 and the + output of the static conversion device 21 drive the water adding mechanism 7 through an AND circuit.

Accordingly, if the concentration is high, the water adding mechanism 7 is driven for a time corresponding to the difference from the set value, and while adding water, the mixed liquid is sent to the temporary storage tank 9, so that the concentration is equal to the set value. Controlled to the same value.

On the other hand, when it is thin, for example, when it is thin by °'1", that is, when the concentration difference signal related to the column C is about 1" smaller than the second column in FIG. 2
The output value of 1 is '1'', and the sign output is - (minus).9
, in the same manner as before, the signal output from the static conversion device 21 is as shown in FIG.
The signal to the terminal and the signal related to the - terminal become high level.

The timer 22 sets the output Q to the .

As a result, when the concentration is low, the drainage mechanism 8 is driven for a time corresponding to the difference from the set value, and the mixed liquid is sent to the temporary storage tank 9 while draining, and the concentration is controlled to the same value as the set value. Ru.

As described above, according to this embodiment, as in the previous embodiment, the concentration of the liquid mixture sent to the temporary storage tank 9 is reliably controlled and the concentration is always constant.

In addition, similar to the example shown in Fig. 3, the quality of seaweed was improved.
It is possible to improve efficiency by not having to wait for the time required for control, and at the same time,
This allows for the simplification of the device.

Therefore, each of the embodiments described above includes at least a seaweed supply mechanism, a mixing tank, and a pump for pouring seaweed into the mixing tank, and the water addition mechanism and drainage mechanism related to the mixing tank are the same. It is equipped with a level detection sensor that detects the L level and H level of the blended solution in the blending tank, a concentration sensor for the blended solution, and a mechanism that stirs the water and seaweed in the blending tank. In devices equipped with a controller that controls the water addition mechanism and drainage mechanism, the concentration of the seaweed and water mixture at a certain level is detected, and the system detects the concentration based on the difference between that concentration and the set value. This system is configured to adjust the amount of water by adjusting the water level, thereby making it possible to always maintain a constant water level, detect the concentration, and send a liquid mixture that matches the set value.

Including the above-mentioned aspects, according to the present invention, it is possible to perform stable concentration control on the blended liquid and obtain a blended liquid that matches the set value, and as a result, uniform seaweed finish can be achieved as desired. It can be said that this invention has excellent practical effects and can be expected to greatly increase profits for businesses.
