It becomes.

The operation preparation 121 is controlled by the operation preparation control function unit 104, and refers to various values set in the operation unit 110 to prepare the operation in the pulp manufacturing unit 200 and the papermaking unit 300.

The pulp production process 122 is controlled by the pulp production unit control function unit 101. In the pulp manufacturing unit 200, the raw material 2 for shredded paper or the raw material 2 for unshredded fixed-shaped paper is supplied to the pulper device 6 by the raw material supply device 8, and is disintegrated in the pulper device 6 to be a pulp slurry. Is manufactured. The pulp slurry obtained by the pulper device 6 is diluted with white water supplied by the diluent supply pump 21A until the fiber concentration reaches about 2% to 4%, and then supplied to the deinking device 10 by the pulp slurry supply pump 20. To do. Further, the white water in the white water tank 18 is supplied to the deinking device 10 by the diluent supply pump 21B to dilute the fiber concentration from 0.5% to 0.6%.

The control unit 100 determines the basic execution processing time for processing the load of each processing unit by the basic function based on the weight of the paper raw material 2 put into the raw material supply device 8 in the operation completion scheduled time calculation unit 107. calculate. Then, the scheduled operation completion time is output to the touch panel 201 of the display unit 109 based on the calculated execution processing time.

Here, in the calculation of the scheduled operation completion time, the control unit 100 corrects the execution processing time based on at least one processing time determining factor involved in the processing by the basic function of the processing unit, and outputs the scheduled operation completion time. .. In the present embodiment, the operation completion time is the time when the fiber processing and the cleaning of the apparatus are completed and the power can be turned off, and the scheduled operation completion time is the time when the power of the apparatus can be turned off. It is the time of.

The processing time determinants involved in the calculation of the scheduled operation completion time include various information related to the pulp manufacturing unit 200 and the papermaking unit 300. For example, it is operation setting information indicating an operation condition, operation status information indicating an actual operation status, operation history information indicating a past operation history, and environmental information indicating an environmental condition. These information are stored in the internal storage unit 111 of the control unit 100 or an external storage device connected via a network.

The individual factors included in each of the above information will be described below.
-Paper type (operation setting information)
Factors that determine the type of paper are fiber length, type / amount of filler, and fiber density. These factors change the adhesion of fibers to bubbles during deinking. Therefore, depending on the type of paper, the amount of fibers that adhere to the bubbles during deinking and are removed together with the toner changes.

Further, the type of paper affects the degree of disintegration, and in order to obtain the same degree of disintegration, it is necessary to change the disintegration time depending on the type of paper.

Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Set release time (operation setting information)
The increase or decrease in the disintegration time is the same as the increase or decrease in the papermaking time. For example, if the disassembly time by the pulper device 6 is increased by 20 minutes, the execution processing time is also increased by 20 minutes. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
-Amount of surfactant to be added when the fibers of the raw material of paper are dissociated (operation setting information)
A surfactant is charged into the pulper device 6 during the disintegration treatment. The amount of the surfactant depends on the weight of the input paper as the raw material of the paper, and the amount of bubbles at the time of deinking in the subsequent process changes depending on the amount of the surfactant. As the amount of foam changes, so does the amount of fiber removed during deinking. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
-Type of surfactant to be added at the time of deinking and set usage amount per unit time (operation setting information)
The amount of bubbles generated by the deinking device 10 changes depending on the type of surfactant and the amount used per unit time, and the amount of fibers removed together with the toner also changes as the amount of bubbles changes. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output. In the present embodiment, the surfactant charged into the pulper device 6 and the surfactant charged into the deinking device 10 are the same.
・ Set deinking time (operation setting information)
The probability that the fibers adhere to the bubbles also changes depending on the deinking time, that is, the time that the fibers pass through the deinking device 10. The longer the deinking time, the higher the probability that the fibers will adhere to the foam and the more fibers will be removed.

Further, a long deinking time is synonymous with a decrease in the flow velocity of the pulp slurry moving in the deinking tank of the deinking device 10. Therefore, as the deinking time becomes longer, the amount of fibers supplied per unit time supplied from the deinking device 10 to the papermaking device 12 decreases. At this time, if the papermaking speed of the papermaking apparatus 12 is not changed, the thickness of the paper to be made becomes thin. Further, in order to maintain the thickness of the paper to be made, it is necessary to slow down the paper making speed, and as a result, the execution processing time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Deinking mode (operation setting information)
The deinking mode includes an eco mode, a normal mode, and a powerful mode, and the amount of bubbles generated differs. Set the deinking level by selecting the deinking mode. In eco mode, the amount of foam is small and the deinking effect is weak, but the amount of fiber lost is small. In the powerful mode, the amount of bubbles is large and the deinking effect is high, but the amount of fibers lost is large. The normal mode is between the eco mode and the powerful mode. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Set papermaking speed (operation setting information)
The papermaking speed is indicated by a set value of the rotation speed of the motor that drives the papermaking wire of the papermaking apparatus 12. When the wet paper made by the paper making wire of the paper making device 12 is sufficiently dried, the wet paper is moved at the same speed as the paper making speed by slowing down the paper making speed. The residence time in the paper drying device 14 becomes long, and as a result, the execution processing time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
-Set paper thickness, set paper density (operation setting information)
If the paper thickness and fiber density to be made are changed without changing the papermaking speed, the amount of fibers used per unit time will change. Therefore, the time required to complete the papermaking by using up the fibers supplied from the deinking device 10 to the papermaking device 12 also changes, and as a result, the execution processing time changes.

For example, if the thickness of the paper to be made is increased or the density is increased, the amount of fiber used per unit time increases and the time until the supplied fiber is used up becomes shorter, resulting in a shorter execution processing time. .. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

The paper thickness and density are changed by changing the speed of the papermaking wire of the papermaking apparatus 12, or changing the flow rate of the pulp slurry from the head box of the papermaking apparatus 12 to the papermaking wire.
・ Set slurry transfer speed (operation setting information)
The set slurry transfer speeds are the transfer speed of the pulp slurry supply pump 20 that transfers the pulp slurry from the pulper device 6 to the deinking device 10, and the deinked pulp that transfers the pulp slurry from the deinking device 10 to the head box of the papermaking device 12. It is a transfer speed of the slurry delivery pump 22, and the transfer speed is indicated by a set value of the rotation speed of the pump.

When the transport speeds of these two pumps are changed, the amount of fibers supplied per unit time supplied to the paper machine 12 also changes. When papermaking with the same thickness and density while the amount of fiber supplied changes, it is necessary to change the papermaking speed.

For example, if the transport speed of the pump is slowed down, the amount of fibers supplied to the paper making device 12 decreases. Therefore, in order to maintain the paper thickness, it is necessary to slow down the papermaking speed, and as a result, the execution processing time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

In the cleaning process, the slurry remains in the pulper device 6 with the white water flowing from the papermaking device 12 into the pulper device 6 via the white water tank 18, the clean water flowing into the pulper device 6 from the clean water supply source 19. It is a mixture of the existing fibers and has a different fiber concentration from the slurry used for papermaking.

The transport speed of the pulp slurry supply pump 20 that transports this slurry from the pulper device 6 to the deinking device 10 affects the cleaning time. If the transport speed is slow, the time for transporting the slurry to the deinking device 10 becomes long, and as a result, the cleaning time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Set white water transport speed (operation setting information)
The set white water transport speed is the transport speed of the diluent supply pump 21A that transports white water from the white water tank 18 to the pulper device 6 and the transport speed of the diluent supply pump 21B that transports white water from the white water tank 18 to the deinking device 10. Yes, the transfer speed is indicated by the set value of the rotation speed of the pump.

The transport speeds of these two pumps affect the start time of the deinking step in the pulper device 6 and the deinking step in the deinking device 10. If the transport speed of the white water supplied to the pulper of the pulper device 6 and the deinking tank of the deinking device 10 is slowed down, the time required for the water level to reach a predetermined level in the pulper or the deinking tank becomes longer, and as a result, Execution processing time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

This set white water transfer speed is also the transfer speed of the diluent supply pump 21A that transfers white water from the white water tank 18 to the pulper device 6 in the cleaning process, and is also the transfer speed of the diluent that transfers white water from the white water tank 18 to the deinking device 10. It is also the transfer speed of the supply pump 21B. The transport speeds of these two pumps affect the cleaning time of the pulper device 6 and the deinking device 10, and if the transport speed is slowed down, it takes a long time to obtain a sufficient amount of water necessary for cleaning, and cleaning is performed. The time will be longer. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Set water transfer speed (operation setting information)
This is the speed at which the clean water used for cleaning is conveyed to the deinking device 10 and the paper making device 12. The transport rate of clean water depends on the water pressure of the clean water supply source 19, for example, the pressure of tap water. If the transport speed of the clean water used during cleaning is slowed down, it takes a long time to obtain a sufficient amount of water required for cleaning, and the cleaning time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Set drainage transfer speed (operation setting information)
The wastewater here is the water used for cleaning the inside of the device after the papermaking process is completed. All the wastewater is conveyed to the outside of the paper processing device 1 by the drainage pump 25 via the deinking device 10 and the deinking and draining liquid processing device 17. The transport speed is indicated by a set value of the rotation speed of the drainage pump 25. When the transport speed of drainage by the drainage pump 25 becomes slow, the cleaning time becomes long as a result. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Actual papermaking speed (operating status information)
The actual papermaking speed indicates the actual papermaking speed, and is indicated by the measured value of the rotation speed of the motor that drives the papermaking wire.

When the papermaking speed fluctuates, the residence time of the wet paper in the wet paper dehydrating device 13 and the wet paper drying device 14 in the post-process in which the wet paper moves at the same speed as the paper making speed fluctuates, and as a result, the execution processing time also fluctuates. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Actual slurry flow rate (operating status information)
The actual slurry flow rate indicates the clogged state of the slurry transport path for transporting the pulp slurry from the pulp manufacturing section 200 to the papermaking section 300, and is indicated by the flow rate at which the pulp slurry actually flows, and is measured by the flow meter 31B here. It is shown by the measured value. When the actual slurry flow rate is lower than the set slurry flow rate, it is determined that the slurry transfer path is clogged. When the actual slurry flow rate decreases, the execution processing time becomes longer as a result. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

Further, it shows the clogged state of the slurry transport path for transporting the pulp slurry from the pulper device 6 to the deinking device 10, and shows the flow rate at which the pulp slurry actually flows. Here, the measured value measured by the flow meter 31A. Indicated by. When the actual slurry flow rate is lower than the set slurry flow rate, it is determined that the slurry transfer path is clogged. When the actual slurry flow rate decreases, the execution processing time becomes longer as a result. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

Further, in the cleaning process, it indicates a clogged state of the slurry transport path for transporting the slurry (clean water + white water + fibers remaining in the pulper device 6) from the pulper device 6 to the deinking device 10, and the slurry is actually It is shown by the flow rate flowing through, and here, it is shown by the measured value measured by the flow meter 31A. When the actual slurry flow rate decreases due to clogging or the like in the slurry transfer path from the pulper device 6 to the deinking device 10, the discharge time of the slurry that has washed the pulper device 6 becomes longer, and the washing time also becomes longer. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Actual slurry transfer speed (operating status information)
The actual slurry transfer speed indicates the speed at which the pulp slurry is actually transferred from the pulp manufacturing section 200 to the papermaking section 300, and the rotation speeds of the pulp slurry supply pump 20 and the deinked pulp slurry delivery pump 22 are measured by a sensor or the like. It is shown by the measured value of the measured actual rotation speed.

The fluctuation of the rotation speed of these two pumps indicates the fluctuation of the transport speed of the pulp slurry. Similar to the clogging of the transport path, when the actual slurry transport speed decreases, the execution processing time becomes long as a result. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

Further, the speed at which the pulp slurry is actually transferred from the pulper device 6 to the deinking device 10 is shown, and the rotation speed of the pulp slurry supply pump 20 is shown by a measured value of the actual rotation speed measured by a sensor or the like.

The fluctuation of the rotation speed of this pump indicates the fluctuation of the transport speed of the pulp slurry. Similar to the clogging of the transport path, when the actual slurry transport speed decreases, the execution processing time becomes long as a result. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

Further, in the cleaning treatment step, the slurry from the pulper device 6 to the deinking device 10, that is, the slurry in which the water (clean water + white water) used for cleaning in the pulper device 6 and the fibers remaining in the pulper device 6 are mixed is conveyed. The actual transport speed of the pulp slurry supply pump 20 affects the cleaning time.

If the actual slurry transfer speed is slow, the time for transporting the slurry to the deinking device 10 becomes long, and as a result, the cleaning time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
-Actual white water transport speed at which the white water supplied to the pulp manufacturing unit 200 is actually transported (operating status information)
The actual white water transport speed is indicated by a measured value of the actual rotation speed measured by a sensor or the like of the rotation speeds of the diluent supply pump 21A and the diluent supply pump 21B.

Fluctuations in the rotational speeds of these two pumps indicate fluctuations in the transport speed of white water. When the actual white water transport speed is lowered, the start time of the dissociation step in the pulper device 6 and the deinking step in the deinking device 10 is delayed, and as a result, the execution processing time becomes long. Further, if the transport speed of white water fluctuates, not only the time when the deinking tank of the deinking device 10 is filled with white water is delayed, but also the fiber concentration of the deinking tank does not meet the set value. Therefore, not only the deinking performance is affected, but also the processing time of the post-process after the deinking process is affected. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

This actual white water transport speed is also the actual transport speed of the diluent supply pump 21A for transporting white water from the white water tank 18 to the pulper device 6 in the cleaning process, and transports white water from the white water tank 18 to the deinking device 10. It is also the actual transfer speed of the diluent supply pump 21B. The transport speeds of these two pumps affect the cleaning time of the pulper device 6 and the deinking device 10, and if the transport speed is slowed down, it takes a long time to obtain a sufficient amount of water necessary for cleaning, and cleaning is performed. The time will be longer. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Actual water transport speed (operating status information)
This is the actual speed at which the clean water used for cleaning is conveyed to the deinking device 10 and the paper making device 12, and is measured by the flow rate measured by the flow meter 31E. If the actual transport speed of the clean water used during cleaning is slowed down, it takes a long time to obtain a sufficient amount of water necessary for cleaning, and the cleaning time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Actual drainage transport speed (operating status information)
It is the actual transfer speed of the wastewater conveyed to the outside of the paper processing device 1 by the drainage pump 25, and the transfer speed is indicated by the value of the actual rotation speed of the pump. The slower transport rate of this wastewater results in longer cleaning times. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Elapsed time from the last operation completion time (operation history information)
If the elapsed time from the previous operation completion time exceeds a predetermined time, a cleaning step is performed before the start of papermaking. Therefore, the start of operation is delayed, and as a result, the execution processing time becomes long. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
-Papermaking time per unit amount of load based on the operation results for the specified number of times performed in the past (operation history information)
The papermaking time per unit weight of the paper raw material 2 is obtained from the input paper weight of the paper raw material 2 in the past predetermined number of operations and the execution processing time from the start of papermaking to the completion of papermaking. The execution processing time corrected by multiplying the obtained papermaking time by the input paper weight of the paper raw material 2 to be input this time is calculated, and the cleaning time is further added to calculate the scheduled operation completion time. Here, individual operating conditions such as the deinking mode and the papermaking speed setting are not considered.
・ Dissolution time per unit amount of load based on the operation results for the specified number of times performed in the past (operation history information)
The disintegration time per unit weight of the paper raw material 2 is obtained from the input paper weight of the paper raw material 2 in the past predetermined number of operations and the processing time of the disintegration step. The calculated disintegration time is multiplied by the weight of the input paper of the raw material 2 of the paper to be input this time to obtain the corrected disassembly time, the execution processing time is corrected by this disassembly time, and the scheduled operation completion time is calculated.
-Washing time per unit amount of load based on the operation results for the specified number of times performed in the past (operation history information)
The cleaning time per unit weight of the paper raw material 2 is obtained from the input paper weight of the paper raw material 2 in the past predetermined number of operations and the processing time of the cleaning processing step. The cleaning time corrected by multiplying the obtained cleaning time by the weight of the input paper of the paper raw material 2 to be input this time is calculated, and this cleaning time is added to the execution processing time to calculate the scheduled operation completion time.
-Papermaking time for each past operating condition (operation history information)
The execution processing time from the start of papermaking to the completion of papermaking in the past operations is divided according to various operating conditions such as papermaking speed, deinking mode, paper thickness, type of paper raw material 2 to be charged, and weight of input paper. It is stored as past data in the internal storage unit 111 of the control unit 100. When the operation is performed under the same operating conditions other than the input paper weight, the papermaking time per unit weight is obtained from the input paper weight and the execution processing time in the memorized past operation. The execution processing time corrected by multiplying the obtained papermaking time by the input paper weight of the paper raw material 2 to be input this time is calculated, and the cleaning time is further added to calculate the scheduled operation completion time.

If there is a difference of a certain amount or more between the actual papermaking time in this operation and the papermaking time of the past data after the operation is completed, it is considered that the cause is a change in one of the operating conditions in the device. The operating conditions and operating results in this operation are added to the storage unit as new data to be saved.

If there is no operation record under the same operation conditions in the past operation, the operation is performed under the operation conditions set in the current operation, and the operation conditions and the operation record are stored in the storage unit after the operation is completed.

Alternatively, if there is no past operation record that matches all of the multiple operation conditions set in this operation and there is a past operation record in which some operation conditions are different, the operation is close to the operation condition set this time. The actual results are selected, the papermaking time per unit weight is corrected in consideration of different conditions, and the scheduled operation completion time is calculated.
・ Dissociation time for each past driving condition (driving history information)
In addition to the set disassembly time, the operating conditions that affect the disassembly time include the type of paper, water temperature, and the set white water transport speed. Even if the set disintegration time is the same, the degree of disintegration differs depending on the type of paper and water temperature. Therefore, in order to obtain the same degree of disintegration, it is necessary to change the set disintegration time depending on the type of paper and water temperature.

If the set white water transport speed and the actual white water transport speed are different and the white water transport time is slowed down, the injection time will be long and the start time of the disaggregation process will be delayed, so that the disaggregation time will be long. Therefore, the scheduled operation completion time corrected based on the disassembly time in the past operation results under the same conditions for the set white water transport speed is obtained.
・ Cleaning time for each past operating condition (operation history information)
Factors that affect the cleaning time include the transport speeds of clean water, white water, slurry, and drainage that flow through the device during cleaning, and the operating conditions include the set clean water transport speed, the set white water transport speed, and the set slurry transport speed. , Set drainage transport speed.

If the transport speed of clean water, white water, slurry, and drainage flowing in the apparatus during cleaning is slowed down, the cleaning time becomes long.

Therefore, for each operating condition of the set clean water transfer speed, the set white water transfer speed, the set slurry transfer speed, and the set drainage transfer speed, the scheduled operation completion time corrected based on the cleaning time under the same conditions in the past operation results is set. Ask.

Further, the amount of fibers removed together with the toner in the deinking device 10 also affects the washing time. Factors that affect the amount of fiber include the amount of paper input, the type of paper, the type of surfactant, the amount of surfactant added during deinking, and the set amount of surfactant used per unit time during deinking. , Set deinking time, deinking mode.

This increase or decrease in the amount of fibers affects the deinking and draining treatment and the drainage time, and the time for the deinking waste liquid treatment increases as the amount of fibers removed increases.

Therefore, the amount of paper to be charged, the type of paper, the type of surfactant, the amount of surfactant to be charged at the time of deinking, the set usage amount of the surfactant to be charged at the time of deinking, the set deinking time, and the deinking For each operation condition in black mode, the estimated operation completion time corrected based on the cleaning time under the same conditions in the past operation results is obtained.
・ Water temperature (environmental information)
The water temperature in the pulper device 6 of the pulp manufacturing unit 200 is a factor that affects the progress of the disintegration treatment. If the water temperature is lower than the planned water temperature, the progress of dissociation will be slow, and it is necessary to set a long dissociation time in order to obtain the same dissociation result as the dissociation process performed under the planned water temperature.

The water temperature in the deinking device 10 of the pulp manufacturing unit 200 is a factor that affects the amount of bubbles generated in the deinking step. When the water temperature is lower than the planned water temperature, the amount of bubbles generated is small, and in order to obtain the same deinking effect as the deinking treatment performed under the planned water temperature, set a long deinking time or disperse in the pulp slurry. Increase the amount of air and increase the amount of foam.

The water temperature also affects the drying time. If the water temperature is low, it takes time to reach a predetermined temperature required for drying in the drying step, so that it may be necessary to correct the execution processing time. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.
・ Temperature (environmental information)
Air temperature is a factor that affects the drying time after papermaking. When the air temperature is low, it is necessary to reduce the transport speed of the paper to be made in order to set a long drying time, and as a result, the execution processing time becomes long. Alternatively, it is necessary to raise the heater temperature in the drying step of the wet paper drying device 14, and the time until the heater reaches an operable temperature becomes longer, and as a result, the execution processing time becomes longer. Therefore, the execution processing time is corrected based on the processing time determining factor, and the scheduled operation completion time is output.

In the above embodiment, the touch panel 201 of the display unit 109 is used as the output unit, but other output units include personal computers, high-performance mobile phones (so-called smartphones), tablets, and mobile terminals connected via a network. There is a display device. Further, it is possible to notify by voice, and it is also possible to notify another device separately from the notification to the operator.

Case, Recalculation and Output In the above-described embodiment, the configuration having the pulp manufacturing unit 200 and the papermaking unit 300 has been illustrated and described, but the present invention also includes the configuration of only the pulp manufacturing unit 200 having no papermaking unit 300. The invention can be carried out.
Example 1 (basic form)

実施例２（稼働状況情報の実スラリー流量に基づく補正）
脱墨装置１０の脱墨槽から抄紙装置１２のヘッドボックスの間における目詰まりに起因して、または脱墨パルプスラリー送出ポンプ２２の回転速度の低下に起因して、設定スラリー流量に対して実スラリー流量が５％低下したときに、抄紙速度を落として紙厚さを変更しない場合を例示する。

Example 2 (Correction based on the actual slurry flow rate of the operation status information)
Actually with respect to the set slurry flow rate due to clogging between the deinking tank of the deinking device 10 and the head box of the papermaking device 12, or due to a decrease in the rotation speed of the deinking pulp slurry delivery pump 22. An example is an example in which the paper making speed is reduced and the paper thickness is not changed when the slurry flow rate is reduced by 5%.

Here, the execution processing time is increased by 0.3 h (18 minutes), and the total operating time is increased by 0.3 h.

実施例３（運転履歴情報の過去に行った実際の製紙時間に基づく補正）
過去３回分の運転実績における実行処理時間と投入紙重量と単位時間当たりの製紙時間を示す。

Example 3 (correction of operation history information based on actual papermaking time performed in the past)
The execution processing time, the weight of the input paper, and the papermaking time per unit time in the operation results for the past three times are shown.

過去３回の運転実績における単位重量当たりの製紙時間の平均値は、０．７６ｈ／ｋｇである。

The average value of the papermaking time per unit weight in the past three operation results is 0.76 h / kg.

When processing the raw material of the paper having a weight of 6 kg of the input paper this time under the condition of this operation record, the execution processing time is as follows.

6 kg x 0.76 h / kg = 4.56 h (approximately 4 hours and 34 minutes)
By adding the disintegration time of 1.5 h and the washing time of 1.0 h, the total operating time is 7.06 h (about 7 hours and 4 minutes).
Example 4 (correction based on execution processing time for each past operating condition, which is operation history information)
The past operation results are stored in the storage unit for each operation condition, and the execution processing time is calculated based on the past operation results in which the operation results match.

This operating condition

過去データ１の運転条件と運転実績

Operating conditions and operating results of past data 1

過去データ２の運転条件と運転実績

Operating conditions and operating results of past data 2

今回の運転条件は、抄紙速度、脱墨モード、紙厚さ、投入用紙種類の全てにおいて、過去データ１の運転条件と同じである。

The operating conditions this time are the same as the operating conditions of the past data 1 in all of the papermaking speed, the deinking mode, the paper thickness, and the type of input paper.

If the operating conditions are the same, it is considered that the papermaking time per unit weight of the input paper is the same, and from the input paper weight of 7.5 kg and the execution processing time of 5.5 h of the operation record of the past data 1, the unit weight The papermaking time of 0.73 h / kg is calculated.

Multiply the calculated papermaking time of 0.73 h / kg by the weight of the input paper in this operation to calculate the corrected execution processing time of 3.65 h, and add the disintegration time of 1.5 h and the cleaning time of 1 h to the total operation. Find the time and output the scheduled operation completion time.
Example 5 (correction based on past execution processing time which is operation history information)
As the past operating conditions and operating results, there are the operating conditions and operating results of the past data 1 in Table 5 shown in the previous Example 4 and the operating conditions and operating results of the past data 2 in Table 6, and the operating conditions of this time. Is shown in Table 7, and there is no past data in which all the operating conditions match.

しかし、過去データ２の運転条件とは、抄紙速度が異なるだけである。このため、過去データ２の運転条件が、今回の運転条件に近いと判断し、この過去データ２の運転実績の数値を採用する。ここでは、単位重量当たりの製紙時間０．８ｈ／ｋｇと今回の運転条件の投入紙重量５．０ｋｇを乗算して実行処理時間４ｈを算出し、これに離解時間１．５ｈ、洗浄時間１ｈを加えて合計運転時間６．５ｈを求め、運転完了予定時刻を出力する。

However, the papermaking speed is different from the operating conditions of the past data 2. Therefore, it is determined that the operating conditions of the past data 2 are close to the current operating conditions, and the numerical values of the operating results of the past data 2 are adopted. Here, the execution processing time 4h is calculated by multiplying the papermaking time 0.8h / kg per unit weight by the input paper weight 5.0kg under the operating conditions of this time, and the disintegration time 1.5h and the washing time 1h are calculated. In addition, the total operation time of 6.5 hours is obtained, and the scheduled operation completion time is output.

Further, instead of adopting the operating conditions of the past data 2 as they are, the operating results corrected for the difference between the papermaking speed of 90% and 95% may be adopted.
