Abstract

PURPOSE:To obtain an accurate duration during operation or suspension by a method wherein, in case of adjustment of time or date of a clock circuit, a period of time from the start of a state to adjustment and a period of time from adjustment to the end of a state are operated separately to add them up. CONSTITUTION:A controller 16 obtains a period of time of each state of operation and suspension in a processing part to grasp the processing situation of the processing part 12 and to control it to keep the processing condition of a work 14 constant. A clock circuit 20 usually outputs times or dates in succession, but times or dates must be adjusted after once batteries are removed for their replacement. For this adjustment, the processing part 12 keeps a suspension. Therefore, not obtaining the duration of a suspension from its start time and end time, but a period of time from its start to adjustment is once stored during adjustment and added to a period of time from adjustment to the end of this suspension.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time management system for managing the state of a controlled system based on the time and date read from a clock circuit which is backed up by a battery and stores the time and date inside the control system. Regarding the method.

2. Description of the Related Art Conventionally, for example, water contained in a developing solution applied to an automatic developing machine evaporates regardless of whether it is in operation or not in operation. Although this evaporation amount is proportional to the time, there is a significant difference between the evaporation amount during operation and during operation stop, so in order to replenish water according to the evaporation amount with time,
It is necessary to accurately measure and store the duration of each state (during operation and suspension of operation).

Generally, a clock circuit is built in a control system (microcomputer, etc.) for controlling the apparatus. This clock circuit is backed up by a battery so that the time can be kept ticking even when the power supply to the control system is cut off.

Therefore, even if the power supply to the control system is temporarily interrupted, the start time and the end time of the operation of the automatic processor can be fetched and calculated to easily obtain the duration of each state. .

In the control system, the evaporation amount is calculated and water is replenished at a separately determined time based on the calculated continuation time. This makes it possible to obtain a stable finish without significantly changing the concentration of the developing solution or the like. It should be noted that the above time management can also be applied as a parameter for determining the replenishment amount when replenishing the replenisher based on the deterioration of the process during operation.

[0006]

However, if the time or date of the clock circuit is adjusted while a certain state (during operation or suspension of operation) is being continued, the memory before the adjustment will be cleared, resulting in an accurate correction. It is not possible to get the duration of driving or rest. For this reason, an error occurs when calculating the replenishment amount of the water content or the replenisher, and it becomes impossible to perform the optimum replenishment.

In view of the above facts, the present invention provides a time management method capable of obtaining an accurate duration time during operation or at rest even if the time or date of the clock circuit in the control system is adjusted during continuation. The purpose is to obtain.

[0008]

According to a first aspect of the present invention, a clock circuit which is backed up by a battery and manages time and date inside a control system is used to perform time management of the state of the controlled system. A time management method, when the time or date of the clock circuit is adjusted, the time from the start of the state to the time of adjusting the time or date,
The duration of the state is obtained by separately calculating and adding the time from the time of adjusting the time or date to the end of the state.

The invention according to claim 2 is characterized in that the controlled system is an automatic developing machine, and the state is during operation or suspension of the automatic developing machine.

[0010]

According to the invention described in claim 1, when obtaining the time from the start to the end of the same state of the controlled system, the time from the start of the state to the time or date adjustment ,
Since the time from the time of adjusting the time or date to the time of ending the state is separately calculated and added, even if the time or date of the clock circuit is adjusted midway,
The exact duration of the condition can be obtained.

According to the second aspect of the present invention, by applying the above-mentioned time management to the time management of the automatic developing machine during operation and during suspension, for example, the respective states (during operation and suspension) It is possible to obtain an appropriate amount of replenisher or diluting water to be replenished.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a processing apparatus 10 according to this embodiment. The processing apparatus 10 has a processing unit 12 as a controlled system, and a work 14 is conveyed to the processing unit 12 for processing.

A signal line 18 from the control unit 16 is connected to the processing unit 12, and the processing unit 12 is controlled according to a signal from the control unit 16.

A clock circuit 20 is built in the control device 16. The clock circuit 20 is operated by a battery (not shown), and is configured to be able to continuously output the time and date even when the power supply to the control device 16 is cut off.

The control unit 16 obtains the time (operating time T _A , operation stop time T _B ) of each state of operation and operation stop in the processing unit 12, and performs processing based on these times T _A and T _B. Control is performed to grasp the processing status of the unit 12 and to maintain the processing conditions of the work 14 constant.

The clock circuit 20 normally outputs the time or date continuously as described above.
After removing the battery, it is necessary to adjust the time or date. When the time or date is adjusted, the processing unit 12 continues to be in a continuous state (for example, an operation stop state). Here, in the present embodiment, instead of obtaining the duration of the operation pause state from the start time and the end time of the operation pause state, the time from the start of the operation pause state to the adjustment time is temporarily stored during the adjustment. ,
It is designed to be added to the time from the adjustment until the end of this operation stop state.

Thus, even if the time or date is adjusted during the suspension of operation, the duration can be accurately obtained during the suspension of operation.

The operation of this embodiment will be described below with reference to the time chart showing the state of the processing apparatus of FIG. 2 and the flow chart of FIG.

In step 100, it is determined whether the processing unit 12 is in operation or in operation suspension. If it is in operation, step 10 is executed.
2, the process proceeds to step 104 when the operation is not in operation.

(During operation) Step 102: Time adjustment
It is judged whether or not
Go to step 106, increment variable I, then
In step 108, the processing unit 12 is in operation and the first
If it is an adjustment, the duration A from the start of operation _IFrom the second time
If it is a later adjustment, the duration A since the last adjustment_IPlayed
Then, the process returns to step 102. This allows time adjustment
Each time A separated by _I(I = 1, 2, ...

If a negative determination is made in step 102, that is, if the time has not been adjusted, the routine proceeds to step 110, where it is determined whether the operation has ended. This step 11
If the answer is 0, that is, if the operation is continued,
Returning to step 102, the above process is repeated.

If the affirmative determination is made in step 110, that is, if it is determined that the operation has ended, the process proceeds to step 112, and if the time has not been adjusted at all, the time A'from the start of operation is adjusted. If it is found, the time A ′ from the time of the final time adjustment is calculated, and the process proceeds to step 114.

In step 114, the value obtained in step 112 is obtained.
A'and A obtained in step 108 _IAdd and drive
Total time T from start to finish_AAsk for.

Next, at step 116, variables I and J are cleared (0), and the routine proceeds to step 118, where time T
After performing processing based on _A , return.

(During suspension of operation) In step 104, it is judged whether or not the time adjustment has been performed, and if a positive judgment is made, the routine proceeds to step 120, where the variable I is incremented,
Next, at step 122, the processing unit 12 is in the operation stop state, and if it is the first adjustment, the duration B _I from the start of the operation stop is
And if the adjustment of the second subsequent calculating the duration B _I from after the last adjustment, the flow returns to step 104. As a result, each time B _I (I
= 1, 2, ...) can be obtained.

If the determination in step 104 is negative, that is, if the time has not been adjusted, the routine proceeds to step 124, where it is determined whether or not the operation suspension has ended. If a negative determination is made in step 124, that is, if the operation suspension is continued, the process returns to step 104 and the above steps are repeated.

If an affirmative determination is made in step 124, that is, if it is determined that the operation stop has ended, the process proceeds to step 126, and if the time has not been adjusted at all, the time B'from the start of operation stop is adjusted to the time. If is performed, the time B ′ from the final time adjustment time is calculated, and the process proceeds to step 128.

In step 128, the value obtained in step 126 is obtained.
B'and B obtained in step 122 _IAdd and drive
Total time T from start to finish_BAsk for.

Next, at step 130, variables I and J are cleared (0), and the routine proceeds to step 132, where time T
After performing processing based on _B , the process returns.

As described above, when the duration of each state of the processing unit 12 is obtained based on the time output from the clock circuit 20, the time adjustment time is used as a delimiter and the operation is added last. , Even if the time is adjusted on the way, the time before that is not canceled or the time is not errored, and the accurate duration (T
_A or T _B ) can be obtained. Therefore, calculation and processing based on this duration (T _A or T _B ) can be performed accurately.

[Application Example] FIG. 4 shows an automatic developing machine 22 to which the present invention can be applied. This automatic processor 22
(Corresponding to the processing device 10) is a film 24 (workpiece 14).
(Corresponding to the above) is sequentially dipped in a developing solution, a fixing solution and washing water, and then dried.

First, the structure of the automatic processor 22 will be described. The automatic developing machine 22 includes a developing tank 26, a fixing tank 28,
A rinse tank 30 and a washing tank 32 are provided, and each processing solution of a developing solution, a fixing solution, and a rinse solution is stored therein.

A rack 36 to which a plurality of roller pairs 34 are attached is arranged in the developing tank 26, the fixing tank 28, and the washing tank 32, and the film 24 is transported in each tank in a substantially U-shape. It is like this. The rinse tank 30 is provided with a roller pair 38, and the lower roller 38A pumps up the rinse liquid and supplies it to the film 24, so that the surface of the film 24 is rinsed.

The film 24 that has passed through the washing tank 32 is conveyed to the drying section 40. The drying section 40 is provided with a plurality of roller pairs 42, and a blowout port 44 for ejecting dry air is provided between the roller pairs 42. Therefore, the film 24 is dried by the drying air while being horizontally conveyed while being sandwiched by the roller pair 42.

Here, for example, the liquid level of the adjacent rinsing tank 30 is maintained at an overflow level and diluted so that the concentration of the fixing liquid stored in the fixing tank 28 does not change due to evaporation of water. The water is supplied to the rinse tank 30 when the water needs to be replenished.

(Operation and Effect in Application Example) The evaporation amount of water can occur both during the operation of the apparatus and during the stop of operation, but the evaporation amount per unit time is different. Therefore, it is possible to replenish an appropriate amount of diluting water by accurately obtaining the time during operation and the time during operation suspension. It should be noted that the replenishment of the vaporized component is performed at regular intervals or once a day, for example, before the start of operation every morning when the amount replenished during operation does not reach the predetermined daily minimum replenishment amount. When replenishing a predetermined amount according to the downtime,
Sometimes this is done on a weekly basis.

Therefore, as in the present embodiment, the clock circuit 2
When calculating the time during the operation and during the operation stop based on the time output by 0, by calculating each time as in the flowchart shown in FIG. 2, it is possible to obtain an accurate replenishment amount of the dilution water. .
