In order to reduce the set amount, controlling the processing amount adjusting means, and, when the storage state of the grain meets the condition for operation stop, stop the operation of the sorting unit, during the operation stop, the The present invention relates to a supply control device for a rice huller configured to execute the initial operation when a storage state of kernels meets a condition for starting operation based on detection information of a storage amount detection unit.

[0002]

2. Description of the Related Art Conventionally, a supply control device for a rice huller detects a storage amount of grains in a mixed rice tank as the storage tank as disclosed in Japanese Patent Application Laid-Open No. 2-245244. As the storage amount detecting means, the kernel storage amount is detected by four levels of upper limit level (S1), first storage level (S3), second storage level (S4), and lower limit level (S2), and the detection is performed. Based on the information, the amount of dewatering is changed and adjusted so that the amount of supply of the grain when the amount of stored grain is reduced below the first storage level and the amount of supply when the amount of stored grain is increased above the second storage level are changed. By increasing or decreasing the supply amount when the storage amount increases above the first storage level and when the storage amount decreases below the second storage level, the kernel storage amount is set between the first storage level and the second storage level. As much as possible When the kernel storage amount decreases below the lower limit level, the operation of the sorting unit is stopped, and when the kernel storage amount increases above the first storage level in the operation stopped state, the operation of the sorting unit is restarted. There was something like that.

[0003]

The above-mentioned conventional structure has a problem in that the loss rate is reduced due to, for example, the type of grain and the growing condition, or the defective grains removed by the sorting process after the loss. In the case where the ratio is large, for example, even if the amount of grain supplied to the evacuation unit is the same, the amount of grain supplied from the evacuation unit to the sorting unit is reduced, and the storage amount of the storage tank is reduced. However, even in such a case, the amount of stored grain is
The separation unit is maintained between the storage level and the second storage level so that the operation of the selection unit is stopped as much as possible.

However, in the above-described conventional configuration, since the configuration is such that the variation in the storage amount is dealt with only by the configuration that changes and adjusts the deaeration amount, there is still room for improvement in the following points.

[0005] In other words, the unit time is determined not only by the above-described variation in the leaching rate and the ratio of defective grains, but also by the sorter in the sorting section depending on whether or not the sorting is easy due to the difference in the type and properties of the grains. In some cases, even if the supply amount from the escape unit is the same, the storage amount of the storage tank will increase or decrease. The fluctuation of the amount is so large that the decrease in the amount of storage caused by the change is greater than the increase in the amount of storage due to the adjustment of the change in the amount of degassing, and the amount of storage falls below the lower limit level, and the sorting unit stops operating. There is.
In addition, the sorting unit consists of dehulled brown rice, untreated rice,
The mixed rice mixed with paddy and brown rice is sorted and collected respectively, the mixed rice is returned to the storage tank and sorted again, and the paddy is treated again in the removal unit. Depending on the sorting situation, the amount of mixed rice returned to the storage tank may be small, but in such a case,
Even if the escape processing amount is increased, the change in the escape processing amount is changed by a unit set amount set in advance.
When the storage amount is increased due to the increase adjustment, the selection unit may stop operating below the lower limit level in time for the reduction of the storage amount.

The present invention eliminates the above-mentioned disadvantages by effectively utilizing the structure of the object-to-be-sorted means provided in this type of huller, and minimizes the operation of the sorting unit. It is an object of the present invention to provide a supply amount control device in a huller capable of performing work efficiently without stopping.

[0007]

According to the first aspect of the present invention, the control means controls the amount of stored kernels to increase the amount of loss during normal operation based on the detection information of the storage amount detecting means. When the value falls below the discrimination level, the selected object transporting unit is changed from the discharge state to the return state only until the set time has elapsed from that time, and then the transport state switching control for switching to the discharge state is executed. .

In other words, the control means determines that the grain storage amount is lower than the determination level for increasing the amount of grain loss, in other words, if the amount of grain removal is not increased, the amount of grain storage decreases and the operation for stopping the operation is stopped. Since the condition is satisfied and the operation of the sorting unit is stopped, the processing amount is increased while the set amount is increased.
From that time, the sorted object transporting means is returned to the returning state only until the set time elapses, and thereafter the discharged state is brought to the discharging state.

[0009] Therefore, by increasing the amount of processing to be processed by the set amount, the amount of grain supplied from the processing unit to the sorting unit is increased, and the selected object conveying means is set in the reducing state. In the normal operation, the sorted material to be discharged to the outside is returned to the storage tank only for a lapse of the set time. For example, the unsorted material to be returned from the sorting unit to the storage tank ( Even if the amount of mixed rice is decreasing, the amount of the processed material returned to the storage tank is increased by returning the sorted material to the storage tank together.

[0010] As a result, the amount of grain stored per unit time fluctuates, the amount of mixed rice returned to the storage tank decreases, and the like. Even if it becomes large,
By suppressing the decrease in the storage amount by increasing the amount of the processing object returned to the storage tank, it is possible to prevent the operation of the selection unit from being stopped as much as possible.

According to a second aspect of the present invention, in the first aspect, the control means determines that the grain storage amount is based on the detection information of the storage amount detection means, based on a determination level for increasing the amount of desquamation. Also, when the value falls below the set lower limit level set to a low level, the operation of the sorting unit is stopped, and the storage amount of the grain is determined to be in a state satisfying the operation stop condition, and the storage amount of the kernel is reduced.越 え る When the operation start determination level set to a level higher than the amount increase determination level is exceeded, the operation of the sorting unit is regarded as a state in which the grain storage state satisfies the operation start condition. Is configured to start.

When the grain storage amount falls below the discrimination level for increasing the shedding amount, the shedding processing amount increases and the conveyance state switching control is executed, so that the grain storage amount increases. Although there is little possibility that the discrimination level is much lower than the discrimination level for grain, the amount of stored grains falls below the set lower limit level set to a level lower than the discrimination level for increasing the amount of loss despite execution of such control. If there is, stop the operation of the sorting unit at that time. If the operation is continued in such a state, there is a possibility that the supply of the grain to the sorting unit is reduced and the proper sorting state cannot be maintained.

According to a third aspect of the present invention, in the second aspect, there is provided a supply state detecting means for detecting whether or not the supply state is such that the grain is being supplied to the drier.
The control means, when the supply state is detected by the supply state detection means, based on the detection information of the storage amount detection means, when the kernel storage amount falls below the discrimination level for increasing the loss amount. When the conveyance state switching control is executed and the supply state detection unit detects that the supply state is not in the supply state, based on the detection information of the storage amount detection unit, the kernel storage amount is used to increase the desquamation amount. The configuration is such that the transfer state switching control is not executed even when the value falls below the determination level.

In the supply state in which the grain is supplied to the crushing unit, the cereal grain is continuously supplied to the sorting unit. Therefore, when the grain storage amount falls below the discrimination level for increasing the crushing amount. By performing the transfer state switching control, the operation can be continued without stopping the operation of the sorting unit as much as possible. or,
In a state in which no grain is supplied to the extraction unit, the kernel is not subsequently supplied to the sorting unit. Does not need to execute the transfer state switching control.
After that, when the grain storage amount falls below a set lower limit set at a level lower than the discrimination level for increasing the shedding amount, the operation of the sorting unit is stopped.

According to a fourth aspect of the present invention, in the first aspect, the control means is configured such that, even after executing the transfer state switching control, the grain storage amount falls below the discrimination level for increasing the loss. If it is in the state, the operation of the sorting unit is stopped.For example, if the operation is continued as it is, the amount of processed material in the sorting unit is reduced, and a state in which an appropriate sorting state cannot be maintained is obtained. Can be avoided beforehand. In addition, such a state is a special situation, for example, the processing in the sorting unit is not performed properly and the number of objects to be sorted is very small. .

According to a fifth aspect of the present invention, in the fourth aspect, there is provided a supply state detecting means for detecting whether or not the grain supply section is in a supply state in which grain is supplied,
The control means, when the supply state is detected by the supply state detection means, based on the detection information of the storage amount detection means, when the kernel storage amount falls below the discrimination level for increasing the loss amount. When the conveyance state switching control is executed and the supply state detection unit detects that the supply state is not in the supply state, based on the detection information of the storage amount detection unit, the kernel storage amount is used to increase the desquamation amount. When the value falls below the determination level, the operation of the sorting unit is stopped.

In the supply state in which the grain is supplied to the crushing unit, the cereal grain is continuously supplied to the sorting unit. Therefore, when the storage amount of the grain falls below the discrimination level for increasing the crushing amount. By performing the transfer state switching control, the operation can be continued without stopping the operation of the sorting unit as much as possible. In a state in which no grain is supplied to the extraction unit, the kernel is not subsequently supplied to the sorting unit. If it falls below, the operation of the sorting unit is stopped.

With this configuration, the discrimination level for executing the transfer state switching control and the discrimination level for stopping the operation of the selection unit are set to the same level, and the discrimination configuration is also used. There is an advantage that the control configuration can be simplified as compared with the setting.

According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the supply state of supplying the kernel to the scraping section and the supply of the kernel to the scraping section are stopped. Supply intermittent means that can be switched to a stop state is provided, and the control means includes
Based on the detection information of the storage amount detection means, if the grain storage amount exceeds the discrimination level for reducing the amount of debris, the supply intermittent means is stopped until the stored amount of grain falls below the determination level for reduction of the deaeration amount. When the stored amount of grains exceeds the discrimination level for reducing the amount of waste, the set time has elapsed since the last time the stored amount of grains exceeded the determination level for reducing the amount of waste. For example, it is configured not to change the subsequent processing amount.

When the amount of stored grain exceeds the discrimination level for reducing the amount of waste, the supply interrupting means is switched to a stop state until the amount of stored grain falls below the determination level for reducing the amount of waste.
While the continuous supply of the grains prevents the grains from overflowing and overflowing the grains, basically, the subsequent deaeration processing amount is reduced by a set amount.
If the set amount of time has passed since the previous time when the amount of stored grain exceeded the determination level for reducing the amount of grain when the amount of stored grain exceeded the determination level for reducing the amount of loss, Not to change the amount of processing.

In other words, if the set time has elapsed from the time when the determination level was exceeded last time to the time when the determination level was exceeded next time, the set time is required to increase by a small amount, and the current判断 Since it can be determined that the processing amount is not too large, do not change the processing amount, and reduce the processing amount excessively so that the storage amount decreases and the sorting unit becomes unnecessarily stopped. I try to avoid becoming as much as possible.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a hulling machine according to the present invention; As shown in FIGS. 2 and 3, the huller includes a paddy tank 1 in which grains are supplied and stored by a transport device (not shown), and a paddy tank for removing the grains supplied from the paddy tank 1.ぷ section 2, wind selection section 3 for removing rice husks and pity etc. from de-processed processed material, processed product after wind selection (mixed rice in which rice and brown rice are mixed)
Mixed rice tank 4 (an example of a storage tank) for storing rice, mixed rice supplied from the mixed rice tank 4 is dehulled brown rice, unhulled unhulled rice, and those brown rice and paddy are mixed. And a collecting unit 6 for collecting the separated brown rice, the mixed rice, and the paddy in a separated state.

The collecting section 6 comprises a paddy collecting section 6a, a mixed rice collecting section 6b, and a brown rice collecting section 6c. The mixed rice collected in the mixed rice collecting section 6b is fed by a first unloading conveyor 7. The paddy is recovered and returned to the mixed rice tank 4 to be sorted again, and the paddy collected in the paddy recovery unit 6a is returned to the padding unit 2 by being pumped up by the second pumping conveyor 8. Then, it is configured to perform the escape processing again. Then, the brown rice collected by the brown rice collecting unit 6c (an example of a sorted product) is lifted by the third lifting conveyor 10 by switching the switching shutter 9 to the outside from the upper discharge port 11 to the outside. The state can be switched between a state of discharging and a state of supplying the mixed rice to the mixed rice tank 4 together with the mixed rice by supplying the mixture to the middle of the return path of the transport bucket 7a in the first conveyor 7. The switching shutter 9 is switched by an electric motor M1, and a switching state detecting sensor S1 for detecting a switching position of the switching shutter 9.
Is provided. Accordingly, the first and third conveyors 7 and 10 and the switching shutter 9 can be used to convey a sorted object that can be switched between a discharge state in which brown rice (sorted substance) is discharged to the outside and a reduction state in which the brown rice is returned to the mixed rice tank 4. Means H will be constituted.

As shown in FIGS. 4 to 6, the sorting section 5 guides the mixed rice with the brown rice and the rice while guiding the mixed rice from one side in the feeding direction (X direction in FIG. 4) along with the swinging movement. And a mixture of a large number of projections 12 for specific gravity difference selection (selection in regions indicated by G, K and M in FIG. 4) in the selection direction (Y direction in FIG. 4) for each of the mixed rice. In a state where a plurality of the plates 13 are in an oblique posture, and in a state where the periphery thereof is surrounded by a wall, the plates 13 are swingably supported by the frame F by four hanging rods 14. One end of the sorting plate 13 is rotated around the longitudinal axis by the eccentric crank mechanism FK by driving the sorting electric motor M2, and the other end is pivotally supported by the end of the swing arm YA. The mixed rice is supplied from the supply port 15 located on the upper side (upper side) in the feed direction (X direction) with respect to the sorting plate 13 by being driven to swing as a whole. The collecting unit 6 provided on the side (lower side) is configured to collect brown rice, mixed rice, and paddy, respectively.

In the sorting unit 5 having such a configuration, since the amount of processing is small at the start of the work, the specific gravity difference sorting is not performed well, and there is a great possibility that a large amount of paddy is mixed into the brown rice. In the initial operation before the lapse of time, the switching shutter 9 is switched to the reducing state to return the brown rice to the mixed rice tank 4, and after the set time has elapsed, the brown rice is switched to the discharging state to remove the brown rice to the outside. It shifts to the normal operation of discharging to

As shown in FIG. 1, at the lower end of the paddy tank 1, an electromagnetically operated paddy tank shutter 16 (supply) for stopping the supply of grains from the paddy tank 1 to the drier 2 is provided. An example of an intermittent means) and an open / close detection sensor S2 for detecting the open / close state of the paddy tank shutter 16 are provided. The paddy tank 1 has a paddy upper limit sensor S3 for detecting whether or not the stored amount of paddy in the paddy tank 1 is larger than a set upper limit value close to the tank full state, and a set lower limit value close to the empty state. Rice lower limit sensors S4 for detecting whether or not the size is smaller are respectively provided.

The pull-out unit 2 is configured such that a pair of left and right rollers 2a are arranged at a set interval, and are driven to rotate in opposite directions at different peripheral speeds. When the paddy passes through the space, the rice husk is removed and the paddy is removed. Between the paddy tank shutter 16 of the paddy tank 1 and the padding unit 2, a feeding roll 17, and a rocking supply amount adjusting plate 18 for changing and controlling the amount of grain supplied to the padding unit 2; An adjusting electric motor M3 for swinging the supply amount adjusting plate, and a potentiometer PM for detecting an opening degree of the supply amount adjusting plate 18.
By changing and adjusting the opening of the supply amount adjusting plate 18, the processing amount per unit time in the screwing unit 2 (a screwing processing amount) can be changed and adjusted. The supply amount adjusting plate 18 and the electric motor M3 constitute a processing amount adjusting means T.

Inside the mixed rice tank 4, three sensors are provided as storage amount detecting means S for detecting the amount of stored grains in the tank. That is, the mixed rice upper limit sensor S5 for detecting whether the storage amount is larger than the set upper limit (upper limit level) close to the tank full state, the storage amount being smaller than the set lower limit value (lower level) close to the empty state. A mixed rice lower limit sensor S7 for detecting whether or not the stored amount is larger than an intermediate set value set at an intermediate level between the set upper limit value and the set lower limit value. Each of the intermediate sensors S6 for detecting is provided, and each sensor is configured to be a pressure-sensitive type that outputs an ON signal when detecting that the pressure is larger than a set pressure. That is, it is detected that the storage amount is above the sensor installation location in the ON state, and that the storage amount is below the sensor installation location in the OFF state.

A control unit 19 is provided as control means using a microcomputer for controlling the operation of each unit. The control unit 19 is provided with the sensors S1 to S
7. Detection information of the potentiometer PM and the like is input, and based on the detection information, the opening / closing operation of the paddy tank shutter 16, the supply amount adjustment operation by the adjustment electric motor M3, and the operation operation of the selection electric motor M2 are controlled. It is configured as follows.

Next, the control operation of the control device 19 will be described with reference to the flowchart of FIG. The operation start of the apparatus is commanded by command means (not shown), the paddy is supplied into the paddy tank 1 and the paddy tank 1 is filled with paddy, the paddy lower limit sensor S4 and the paddy upper limit sensor S3 are turned ON, respectively, and If the mixed rice upper limit sensor S5 is OFF, the paddy tank shutter 16 is opened and the mixed rice tank 4
To start paddy supply (Steps 1 to 7). If there is no paddy in the paddy tank 1 or if the paddy rice tank 4 is full of paddy, the paddle tank shutter 16 is closed (steps 3 and 6).

When the paddy is supplied to the mixed rice tank 4 and the mixed rice upper limit sensor S5 is turned on, the operation of the sorting unit 5 is started (steps 8 and 9). That is, the driving of the selection electric motor M2 is started. Here, in the initial operation in which the operation of the selection unit 5 is started, the switching state detection sensor S1 is used.
Based on this information, the switching shutter 9 is set to the reduction state until a set time has elapsed from the start of operation, and then switched to the discharge state to execute normal operation. In other words, in the early stage of operation, the amount of processed material on the separation plate is small, and stable specific gravity difference selection cannot be performed properly.
In the initial operation until the set time elapses, brown rice as a sorting object is reduced and circulated to the mixed rice tank 4.

After the operation of the sorting unit 5 is started, when the mixed rice lower limit sensor S7 is turned off and the stored amount falls below the lower limit level (when the operation stop condition is satisfied), the processing amount is reduced. Since the operation of the sorting unit 5 is stopped because of the decrease and the proper sorting operation cannot be performed, the stored rice amount is recovered until the mixed rice upper limit sensor S5 is turned on and exceeds the upper limit level (when the condition for starting operation is satisfied). ) The operation of the sorting unit 5 is started (steps 10, 11, 12). When the mixed rice upper limit sensor S5 is turned on, if the operation is continued as it is, the mixed rice may overflow from the mixed rice tank 4, so that the paddy tank shutter 16 is closed to stop the supply, and the previous time the mixed rice upper limit sensor was used. If the set time (20 minutes) has not elapsed since S5 was turned on, the adjusting electric motor M3 is operated to adjust the supply amount so as to decrease the set unit amount based on the detection information of the potentiometer PM (step). 13, 14, 15, 16). At this time,
If the ON operation of the mixed rice upper limit sensor S5 is such that the set time (20 minutes) has elapsed since the last time the mixed rice upper limit sensor S5 was turned ON, the supply amount change adjustment is not performed. Thus, the possibility that the storage amount will decrease due to excessive adjustment is reduced. Then, the mixed rice upper limit sensor S
When 5 is turned off, the paddle tank shutter 16 is opened (step 17).

Then, when the intermediate sensor S6 is turned off and the stored amount falls below the intermediate set value, the circulation adjustment control described later is executed. That is, when the storage amount falls below the intermediate set value, the rice lower limit sensor S4 is in the ON state, and
If the supply of grains from the to the mixed rice tank 4 is being performed, the adjusting electric motor M3 is operated to adjust the supply amount based on the detection information of the potentiometer PM so as to increase the set unit amount. (Steps 18, 19, 2)
At the same time, the switching electric motor M1 is operated to switch the switching shutter 9 to the reduction state based on the detection information of the switching state detection sensor S1 (step 21). In other words, the paddy lower limit sensor S4 corresponds to a supply state detecting unit that detects whether or not the grain is being supplied to the drying unit 2. Set time (2
When 0 seconds have elapsed, the switching electric motor M1 is operated to switch the switching shutter 9 to the original discharge state based on the detection information of the switching state detection sensor S1 (steps 22 and 23). Such processing corresponds to the transfer state switching control. In this way, the brown rice is returned to the mixed rice tank 4 only during the set time, so that the storage amount of the mixed rice tank 4 is increased, and the disadvantage that the sorting unit 5 stops is minimized. I have to. Note that when the storage amount falls below the intermediate set value, the rice lower limit sensor S4 turns off the OF.
If the state is the F state and the supply of the grain from the drying unit 2 to the mixed rice tank 4 is not performed, such a transfer state switching control is not executed. Thereafter, when the operation stop is instructed by the command means (not shown), the operation of each part is stopped and the operation is completed (step 24).

[Another Embodiment] (1) In the above embodiment, a configuration in which three sensors are provided as storage amount detecting means has been exemplified. Instead of such a configuration, for example, as shown in FIG. A mixed rice upper limit sensor S5 for detecting whether the storage amount is larger than a set upper limit value close to the tank full state, and mixing for detecting whether the storage amount is smaller than the set lower limit value close to the empty state. The storage amount detection means S may be configured by two sensors, that is, the rice lower limit sensor S7, and the control may be executed as described below. The description of the same contents (steps 30 to 37) as in the flowchart of the above embodiment is omitted.

As shown in FIG. 9, when the mixed rice lower limit sensor S7 is turned off and the storage amount falls below the lower limit level after the operation of the sorting unit 5 is started, when the storage amount falls below the lower limit level, If the paddy lower limit sensor S4 is in the OFF state and the supply of the grains from the dehulling unit 2 to the mixed rice tank 4 is not performed (when the condition for stopping the operation is satisfied), the sorting unit 5 Stop operation. After that, when the paddy supply is started and the mixed rice upper limit sensor S5 is turned ON and the stored amount recovers until the upper limit level is exceeded (when the condition for starting operation is satisfied), the operation of the sorting unit 5 is started (step S5). 38 ~
42).

When the rice lower limit sensor S4 is turned on when the stored rice lower limit sensor S7 is turned off and the stored amount falls below the lower limit level, the operation of the sorting unit 5 is stopped without stopping the operation of the sorting unit 5. The motor M3 is operated to adjust the supply amount based on the detection information of the potentiometer PM so as to increase the set unit amount (steps 40 and 43), and the switching electric motor M1 is operated to switch the switching state detection sensor S1. The switching shutter 9 is switched to the reduction state based on the detection information (step 44). When a set time (20 seconds) elapses after switching to the reduction state, the switching electric motor M1 is operated to switch the switching state detection sensor S1.
The switching shutter 9 is switched to the original discharge state on the basis of the detection information (steps 45 and 46). In this way, the brown rice is returned to the mixed rice tank 4 only for the set time, and the storage amount of the mixed rice tank 4 is increased, so that the disadvantage that the sorting unit 5 stops is avoided as much as possible.

Even after executing the control for switching to the reduction state (corresponding to the conveyance state switching control), the mixed rice lower limit sensor S7 is turned off and the grain storage amount is lower than the lower limit level. If the condition for stopping the operation is satisfied, the operation of the sorting unit is stopped (steps 47 and 41).

When the mixed rice upper limit sensor S5 is turned ON, the mixed rice may overflow from the mixed rice tank 4 if the operation is continued as in the above embodiment.
Close the paddy tank shutter 16 to stop the supply, and if the set time (20 minutes) has not elapsed since the last time the mixed rice upper limit sensor S5 was turned on, operate the adjusting electric motor M3. The supply amount is adjusted to decrease by the set unit amount based on the detection information of the potentiometer PM (steps 48 to 51). At this time, the ON operation of the mixed rice upper limit sensor S5 was previously performed by the mixed rice upper limit sensor S5.
If the set time (20 minutes) has elapsed since 5 was turned on, the supply amount should not be adjusted to reduce the possibility that the stored amount would decrease due to excessive adjustment. , And thereafter, the mixed rice upper limit sensor S5
Is OFF, the paddle tank shutter 16 is opened, and thereafter, when operation stop is instructed by a command unit (not shown), the operation of each unit is stopped and the operation is terminated (Step 52). , 53).

In this embodiment, since the storage amount detecting means is composed of two sensors, the number of parts is smaller and the configuration is simpler than in the above-described embodiment in which three sensors are provided. Become something.

In this embodiment, the mixed rice upper limit sensor S5 for detecting whether or not the storage amount is larger than the set upper limit close to the tank full state, the storage amount being smaller than the set lower limit close to the empty state. Rice lower limit sensor S for detecting whether or not
7, the storage amount detecting means S is constituted by two sensors, but instead of such a lower limit sensor, a sensor located at a higher level (a level close to the intermediate level) is used to increase the deaeration amount. May be configured to detect whether or not the value is lower than the discrimination level for use.

(2) In the above-described embodiment, the storage amount is detected stepwise by a plurality of pressure-sensitive sensors as the storage amount detection means. May be detected, and the configuration is not limited.

(3) In the above embodiment, when the amount of stored kernel exceeds the discrimination level for decreasing the amount of loss, if the set time has not elapsed since the previous time, the amount of processing to be reduced is changed. However, instead of such a configuration, the escape processing amount may be changed.
