[0002]

2. Description of the Related Art Conventionally, when a predetermined amount of fluid is supplied or a main and sub-fluids are mixed at a predetermined mixing ratio, a batch processing system is generally employed. In particular, when mixing the sub-fluid with the main fluid at a predetermined mixing ratio set in advance, a pump for supplying a predetermined amount of the main fluid, a main fluid supply path including a flow meter and a valve, and a pump for supplying the sub-fluid , A sub-fluid supply path composed of a flow meter and a valve, and a batch control unit for controlling the main fluid supply path and the sub-fluid supply path. With this system, a mixed fluid having a predetermined mixing ratio can be obtained. ing. The batch control unit used in this batch processing system presets the supply amount of the sub-fluid with respect to the supply amount of the main fluid, and turns on a start / stop switch (not shown) to start this processing. It has become so.
Then, when the supply of the main fluid is stopped and the supply of the sub-fluid is also supplied in an amount corresponding to the mixing ratio, the supply is automatically stopped, and the first batch processing is completed. By repeating this, a mixed fluid having a predetermined mixing ratio is continuously obtained.

[0003]

However, in such a batch processing system, if the power supply for controlling and controlling the batch equipment during this processing operation is interrupted during this operation, it is set in the batch control section. The batch processing stops even if the supply amount has not been reached, and stops in the middle of the supply, and even if the power is restored, the batch processing is not automatically resumed and continued.
It is necessary to restart the process by pressing the stop switch. For this reason, if the operator does not constantly monitor whether or not a power failure has occurred, normal processing is considered to have been completed and processing may be incorrectly performed. Not obtained. Furthermore, in the case of a so-called momentary power failure in which the supply of power is temporarily interrupted, it is not possible to confirm that the power failure has occurred, and it may be treated as if batch processing was interrupted due to malfunction, and the obtained fluid Although they are correct set amounts or have a predetermined mixing ratio, they have problems such as being determined to be defective.

[0004] It is an object of the present invention to solve such a problem and to provide a power failure stop display device for surely displaying that there is evidence of a power failure during a batch processing operation.

An upper portion of the set value display section 2 receives a flow signal output every time a fluid passes from a flow meter (not shown) constituting a main fluid supply system (not shown) to which the main fluid is supplied. A total display section 3 for totalizing and displaying the total is provided. An output indicator 4 such as an LED for indicating the respective processing and output display states is disposed above the total display section 3, and a supply fluid for supplying a main fluid or a sub-fluid is provided on the left side of the set value display section 2. Among the paths (not shown), a setting indicator 5 indicating a set supply path is arranged.

Below the total display section 3 and the set value display section 2, setting operation switches 6 for setting numerical values for each digit of the display sections 3 and 2 are arranged corresponding to the digits. Have been. Further, operation switches 20 for processing, which are operated according to the respective purposes, are arranged in a row below the operation switches. In the operation switch 20 for this processing, reference numeral 21 denotes a start / stop switch for manually starting and stopping the batch processing operation, and next to the start / stop switch is a display switch for switching the display of the already displayed total integrated value or calculated value. The switch 22. Also, 23
Is a set value changeover switch for changing the set value of the set value display section 2 which has already been set. On the right side, a reset switch 24 for resetting the total integrated value of the total display section 3 and for canceling batch processing is provided. Is arranged.

Further, when the power supply 7 shown in FIG. 1 is interrupted during the batch processing operation, all of the output indicator lamps 4 at the upper part of the counter case 1 for indicating the output display state are not displayed. Then, a blinking display is provided, and the blinking display is built in the batch processing operation control unit 10 which stores that the control signal output has been turned off, as shown in FIGS. 1 and 2. The output is performed by a signal output indicating that the batch processing signal was being output from the storage unit 12 in the middle.

As described above, the main fluid supply path and the sub-fluid supply path used to produce a predetermined amount of mixed fluid at a predetermined mixing ratio of the main fluid and the sub-fluid take in signals from the respective fluid supply paths. It is controlled by a batch control unit 11 of a batch processing operation control unit 10 for processing, and the batch control unit 11 includes a pump (not shown), a flow meter, and a valve (not shown) disposed in main and auxiliary fluid supply paths. , Etc., are electrically connected to the respective batch devices 13 to receive signals from them and to supply signals to them.

By continuing this batch processing operation continuously, a predetermined amount of mixed fluid having a predetermined mixing ratio set in advance is obtained, and one cycle of the batch processing operation ends. On the other hand, when the current supply from the power supply 7 is stopped during the batch processing operation, that is, when a so-called power failure occurs, the control signal output from the batch processing operation control unit 10 (integrated value, set value, output in the middle of Control signal) is stored. The stored control signal output is held until the power failure state is restored, at which point the batch processing operation is interrupted. Then, at the same time when the power supply 7 is restored, the integrated value / set value of the control signal output is displayed, and a control signal indicating that the output of the batch processing is being output is output to output the output indicator light 4 for displaying the output display state. Flashes. After this, the start / stop switch 21
Is turned on, the output indicator lamp 4 is turned off, and the batch processing operation can be resumed. Thereafter, the start / stop switch 21 is turned on to restart the batch processing operation. When the mixed fluid having the preset mixing ratio reaches a predetermined amount, the batch processing operation ends.

In this embodiment, the use of the main fluid and the sub-fluid in a batch process for obtaining a mixed fluid having a preset mixing ratio has been described. However, the present invention is not limited to this. The same can be used in batch processing for obtaining a predetermined amount of fluid.

[0012]

As is apparent from the above-described embodiments, the present invention relates to a batch processing system for calculating a supply amount in order to obtain a predetermined amount of fluid. The unit 10 has a built-in storage unit 12 for sequentially storing a set value at the time of a power failure and a total integrated value of a supply amount. The storage unit 12 stores that a batch processing signal is being output, and the batch processing is performed when the power is restored. Since this is a power failure stop display device that provides a signal output indicating that the signal was being output to the output indicator lamp 4 as an electric signal, the power supply for controlling the power supply during the processing operation is interrupted. Even when the power is restored, it is possible to accurately confirm that a power failure has occurred during the batch processing operation, and it is easy to determine whether a malfunction has occurred. After confirming this, the operator can press the start / stop switch to restart the processing operation, so that the restart of the batch processing operation is ensured. Further, there is no need to constantly monitor whether or not a power failure has occurred during the work, and it is possible to immediately return to the normal processing state when the power failure is recovered, and there is no suspicion that the counter is broken. And the reliability of the batch processing system is improved. In addition, even in the case of a so-called momentary power failure in which the power supply is temporarily interrupted, the obtained mixed fluid has the correct mixing ratio without processing as if the batch processing operation was interrupted due to power failure or malfunction. Therefore, it is possible to obtain a specific effect such as a reduction in discarding as a defective product.
