When the 1st key~the 3rd key 32~34 of operation portion 35, any one is pressed, as illustrated in the flow chart of fig. 9,
CPU 51 makes display unit 31 show features at a glance picture 71 (referring to Figure 10) (step 1, hereinafter referred to as " S1 ").Such as the X1 of Figure 10
It is shown, initial value is shown first in features at a glance picture 71.When user presses the 2nd key 33 or 3 key 34, CPU 51 via
Input and output portion 44 receives input operation, and reads the identification of function being stored in EEPROM 54 number.Then, CPU
Instruction is shown that the display signal of read identification of function number is sent to display unit 31 via input and output portion 44 by 51.By
This shows such as identification of function number " F1 " as shown in the X2 of Figure 10 in features at a glance picture 71.As user presses the 2nd
Key 33 or the 3rd key 34, identification of function number are changed.
As shown in figure 9, CPU 51 judges whether to have selected function (S2).When the 1st key 32 is not pressed, CPU 51 sentences
Break as non-selected function (S2: no).At this point, CPU 51 judges whether to have passed through stipulated time (S24).Pass through it in the stipulated time
Before (S24: no), CPU 51 waits the 1st key 32 to be pressed in the state of display function list screen 71.On the other hand, it is passing through
The stipulated time is spent but in the case that the 1st key 32 is not pressed (S24: yes), CPU 51 terminates control shown in Fig. 9.As a result,
It can be avoided actuation means 1 to be placed in the state that function is unselected.
When user presses 1 key 32 at the appointed time, CPU 51, which is judged as, selected function (S2: yes).Then,
CPU 51 judges that selected function is the 1st function or the 2nd function (S3).If indicating the identification of function number quilt of the 1st function
When being shown in display unit 31, user presses the 1st key 32, then CPU 51, which is judged as, has selected the 1st function (the S3: the 1 function).This
When, CPU 51 sends the display signal of instruction display preset numbers setting screen 73 via input and output portion 44 (referring to Figure 10)
To display unit 31, display unit 31 is made to show preset numbers setting screen 73 (S4).As shown in Figure 10, picture is set in preset numbers
Face 73 shows identification of function number (X3 in figure) and preset numbers (X4 in figure).So-called preset numbers refer to and move for identification
The identification information of operation mode.In the present embodiment, such as up to 8 action modes be can store, each action mode is assigned
Preset numbers " P1 "~" P8 ".As user presses the 2nd key 33 or the 3rd key 34, CPU 51 changes preset numbers (X4 in figure).
As shown in figure 9, CPU 51 does not set preset numbers (S5: no) before user presses the 1st key 32.On the other hand,
When user presses 1 key 32, the preset numbers that CPU 51 is displayed in preset numbers setting screen 73 are stored in RAM 53,
Thus preset numbers (S5: yes) is set.Then, instruction display preset numbers are determined that the display signal of picture 74 is sent by CPU 51
To display unit 31, display unit 31 is made to show that preset numbers determine picture 74 (S6).As shown in the X5 of Figure 10, preset numbers are determined
Picture 74 is to show set preset numbers, not display function identiflication number.
Next, as shown in figure 9, CPU 51 is by the display signal of instruction display initial pressure input picture 75 via input
Output section 44 is sent to display unit 31, and display unit 31 is made to show initial pressure input picture 75 (S7).For example, as shown in Figure 10,
If the 1st key 32 is pressed in the state of showing that preset numbers determine picture 74, the display of display unit 31 is from preset numbers
Determine that picture 74 switches to initial pressure input picture 75.Expression input initial pressure is shown in initial pressure input picture 75
The process number (referring to N1 in figure) of Pf and the input value (M1 in figure) of initial pressure Pf.Herein, so-called initial pressure Pf, refers to
Start the setting value of operating pressure when valve control (control of the operating pressure of cylinder 17) according to action mode.CPU 51 via
Input and output portion 44 receives the input operation of the 2nd key 33 or the 3rd key 34, and according to the defeated of input operation change initial pressure Pf
Enter value (M1 in figure).As shown in figure 9, CPU 51 does not set initial pressure Pf (S8: no) before user presses the 1st key 32.
On the other hand, when user presses 1 key 32, CPU 51 sets initial pressure Pf (S8: yes).That is, CPU 51 will
The input value of the shown initial pressure Pf out of initial pressure input picture 75 is stored in RAM as the setting value of initial pressure Pf
53。
Next, CPU 51 sends out the display signal for indicating displaying target pressure input picture 76 via input and output portion 44
It send to display unit 31,31 displaying target pressure of display unit is made to input picture 76 (S9).For example, as shown in Figure 10, in goal pressure
The input value for indicating process number (N2 in figure) and goal pressure Pe of input goal pressure Pe is shown in input picture 76
(M2 in figure).Herein, so-called goal pressure Pe refers to operating pressure when carrying out feedforward control to the operating pressure of cylinder 17
Setting value.Then, as shown in figure 9, CPU 51 judges whether to set the input value (S10) of goal pressure Pe.The place of S9, S10
Reason is identical as the processing of S7, S8, so omit the description.
In the case where setting the input value of goal pressure Pe (S10: yes), CPU 51 will be used via input and output portion 44
It is sent to display unit 31 in the display signal of display delay time input picture 77, the 31 display delay time of display unit is made to input picture
Face 77 (S11).For example, as shown in Figure 10, showing the process for indicating input delay time Td in delay time input picture 77
Number the input value (M3 in figure) of (N3 in figure) and delay time Td.Herein, so-called delay time Td refers to according to movement mould
Formula starts the time that valve control (control of the operating pressure of cylinder 17) maintains initial pressure Pf afterwards.CPU 51 is via input and output
Portion 44 receives the input operation of the 2nd key 33 or the 3rd key 34, and correspondingly changes the input value of delay time Td with input operation
(M3 shown in Fig. 10).CPU 51 does not set delay time Td (S12: no) before user presses the 1st key 32.
On the other hand, when user presses 1 key 32, CPU 51 sets delay time Td (S12: yes).That is, CPU 51 will
Input value shown by delay time input picture 77 is stored in RAM 53 as the setting value of delay time Td.
Then, CPU 51 makes the input value (M4 shown in Fig. 10) for showing process number (N4 of Figure 10) and clearance time Ts
Clearance time input picture 78 (Figure 10) be shown in display unit 31 (S13), when pressing 1 key 32, by shown input
Value is set as clearance time Ts (S14: yes).Herein, so-called clearance time Ts, refers to until making initial pressure Pf reach target pressure
Time until power Pe.Then, CPU 51 makes input value (Figure 10 institute for showing process number (N5 of Figure 10) and repetition time Tr
The M5 shown) repetition time input picture 79 (referring to Figure 10) be shown in display unit 31 (S15), when pressing 1 key 32, will
Shown input value is set as repetition time Tr (S16: yes).Herein, so-called repetition time Tr, be instigate initial pressure Pf and
Interval time when goal pressure Pe changes repeatedly.Input value (M5 shown in Fig. 10) be "-" when, refer to initial pressure Pf and
Goal pressure Pe does not change repeatedly.The processing of S13 and S15 is identical as the processing of S11, and the processing of S14 and S16 are identical as S12,
So omitting the description.
It should be noted that the terminal of delay time Td is equivalent to when initial pressure Pf being made to start to change to goal pressure Pe
Time.Moreover, the terminal of clearance time Ts is equivalent to time when reaching goal pressure Pe.Therefore, pass through the place of S7~S14
Reason sets the setting value of the operating pressure of 2 each time.
Then, as shown in figure 9, when CPU 51 is based on the initial pressure Pf, goal pressure Pe, delay being stored in RAM 53
Between Td, clearance time Ts, repetition time Tr and generate action mode, be stored in EEPROM 54 (S17).
For example, initial pressure Pf is set greater than the value of 0kPa by user, goal pressure Pe is set greater than initial pressure
Delay time Td and clearance time Ts, are set greater than 0 second value by the value of power Pf, and repetition time Tr is set as "-".This
When, CPU 51 generates action mode as shown in figure 11, that is, operating pressure is made only to become mesh through 1 variation from initial pressure Pf
Mark the action mode of pressure Pe.Figure 11 is the image for generating action mode, and the longitudinal axis indicates operating pressure (kPa), when horizontal axis indicates
Between (sec).
And on the other hand, when user sets numerical value to repetition time Tr, as shown in figure 12, CPU 51 generates following dynamic
Operation mode, that is, the change of initial pressure Pf and goal pressure Pe are repeated according to the interval of delay time Td set in S14
It is dynamic.Figure 12 is the image for generating action mode, and the longitudinal axis indicates operating pressure (kPa), and horizontal axis indicates time (sec).
(what is set in S5 is pre- with the preset numbers that are stored in RAM 53 by the action mode generated as shown above by CPU 51
If number) it is stored in association in EEPROM 54.Therefore, CPU 51 can be read using preset numbers as actual parameter
Action mode.
Then, CPU 51 makes display unit 31 show that picture 80 (S18) is completed in action mode registration.For example, such as the X6 of Figure 10
Shown, action mode registration is completed to show the default volume for the action mode being stored in S17 in EEPROM 54 in picture 80
Number, i.e. the preset numbers that set in S5.User is able to recognize that the registration of action mode has been completed as a result,.Then, 51 CPU
Terminate control shown in Fig. 9.It should be noted that the processing of S4~S17 is an example of action mode storage processing.In addition, S7,
The processing of S9, S11, S13, S15 are to show an example of processing.
Referring to Fig. 5~Fig. 8, specifically describe process action mode being stored in EEPROM 54.Herein, operation pressure
When power is 5kPa, the valve opening of actuation means 1 becomes complete open state.
For example, initial pressure Pf is set as " 0kPa " via operation portion 35 by user, goal pressure Pe is set as
" 5kPa ", is set as " 0sec " for delay time Td, and clearance time Ts is set as " 5sec ", repetition time Tr is set as
"-".At this point, as shown in figure 5, CPU 51 generate the 1st action mode, that is, according to action mode start valve control (cylinder 17
The control of operating pressure) while increase operating pressure, gently operating pressure was made to be increased to 5kPa from 0kPa by 5 seconds.
Moreover, preset numbers " P1 " and the 1st action mode are stored in association in EEPROM 54 by CPU 51.
In addition, goal pressure Pe is set as example, initial pressure Pf is set as " 0kPa " by operation portion 35 by user
" 2kPa ", is set as " 0sec " for delay time Td, and clearance time Ts is set as " 5sec ", repetition time Tr is set as
"-".At this point, as shown in fig. 6, CPU 51 generates the 2nd action mode, that is, make to grasp while starting valve control according to action mode
Make pressure rise, operating pressure is gently made within 5 seconds to reach 2kPa from 0kPa.Moreover, CPU 51 is by preset numbers " P2 " and is somebody's turn to do
2nd action mode is stored in association in EEPROM 54.
In addition, goal pressure Pe is set for example, initial pressure Pf is set as " 2.5kPa " via operation portion 35 by user
For " 2kPa ", delay time Td is set as " 5sec ", clearance time Ts is set as " 0sec ", repetition time Tr is set as
"-".At this point, as shown in fig. 7, CPU 51 generates the 3rd action mode, that is, will be grasped while starting valve control according to action mode
Make pressure control and operating pressure is reduced to 2kPa from 2.5kPa immediately after maintaining this state 5 seconds in 2.5kPa.Moreover,
3rd action mode and preset numbers " P3 " are stored in association in EEPROM 54 by CPU 51.
In addition, goal pressure Pe is set as example, initial pressure Pf is set as " 5kPa " via operation portion 35 by user
" 2kPa ", is set as " 5sec " for delay time Td, and clearance time Ts is set as " 2sec ", repetition time Tr is set as
"-".At this point, as shown in figure 8, CPU 51 generates the 4th action mode, that is, will while starting valve control according to action mode
Operating pressure control is in 5kPa, and after this state is maintained 5 seconds, changing operating pressure from 5kPa is 2kPa.CPU 51 will
Preset numbers " P4 " and the 4th action mode are stored in association in EEPROM 54.
Therefore, user sets initial pressure Pf, target only by viaing operation portion 35 on one side watch display unit 31 while
Pressure Pe, delay time Td and clearance time Ts, so that it may CPU 51 be made to generate different move in a simple manner according to demand
Operation mode, and it is stored in EEPROM 54 in a manner of identifiable.It is shown that is, user can be watched by one side
Show that portion 31 is operated and set on one side the setting value of the operating pressure of each time to operation portion 35, therefore, actuation means 1 are only
Action mode can be stored by own device.
Then, on one side referring to Fig. 9, the control to selecting action mode by operation portion 35, acting actuation means 1 on one side
Process is illustrated.
For example, user presses the 2nd key 33 or the 3rd key 34, the function of indicating the 2nd function is shown in features at a glance picture 71
Identiflication number, and press the 1st key 32.Then, CPU 51 be judged as selected function be the 2nd function (S1, S2: being, S3: the 2
Function).
At this point, the display signal for being used to show preset numbers assigned picture is sent to by CPU 51 via input and output portion 44
Display unit 31 makes display unit 31 show preset numbers assigned picture (S19).CPU 51 is according to the operation of the 2nd key 33 or the 3rd key 34
The preset numbers being stored in EEPROM 54 are sequentially displayed in preset numbers assigned picture (not shown).The 1st key 32 not
When being pressed, CPU 51 is judged as not specified preset numbers, standby (S20: no).On the other hand, when the 1st key 32 is pressed,
CPU 51 is judged as the preset numbers (S20: yes) specified and be shown in preset numbers assigned picture.
CPU 51 judges whether have and the specified consistent preset numbers of preset numbers (S21) in EEPROM 54.
When not having a consistent preset numbers (S21: no), CPU 51 carries out error notification (S25), and terminates control shown in Fig. 9.
On the other hand, there are (S21: yes) when consistent preset numbers, read from EEPROM 54 and preset with specified
Corresponding action mode is numbered, and is stored in RAM 53 (S22).
Then, CPU 51 makes the operation of the beginning cylinder 17 of pressure control portion 43 according to the action mode being stored in RAM 53
The control (S23) of pressure.Specifically, CPU 51 is sent out according to the action mode being stored in RAM 53 to pressure control portion 43
Send the control signal for temporally indicating the setting value of operating pressure.Pressure control portion 43 controls supply solenoid valve 5 and exhaust is used
Solenoid valve 6 so that the operating pressure detection value detected by pressure sensor 7 with received operating pressure setting value one
It causes.Then, CPU 51 is ended processing.It should be noted that the processing of S20~S22 is an example of action mode reading process.
The processing of S23 is an example of control processing.
Referring to Fig. 5~Fig. 8, for the process by 35 required movement mode of operation portion, the valve opening for controlling actuation means 1
It is concretely demonstrated.
Specifically, for example, when user specifies preset numbers " P1 " via operation portion 35, CPU 51 is by preset numbers
" P1 " is used as actual parameter, and the 1st action mode shown in fig. 5 is read from EEPROM 54.CPU 51 will be by the 1st action mode
The control signal of the time instruction operating pressure of defined is sent to pressure control portion 43.Pressure control portion 43 is based on control letter
Number, supply solenoid valve 5 and electromagnetic valve for air discharge 6 are controlled, so that the operating pressure detection value detected by pressure sensor 7
It is consistent with the operating pressure that CPU 51 is indicated.Actuation means 1 rise to operating pressure slowly from 0kPa through 5 seconds as a result,
After 5kPa, 5kPa is maintained.Therefore, the valve opening of actuation means 1 becomes full open position from completely closed state, does not have
Punching.
In addition, for example, CPU 51 makees preset numbers " P2 " when user specifies preset numbers " P2 " via operation portion 35
For actual parameter, the 2nd action mode shown in fig. 6 is read from EEPROM 54.Identically as above-mentioned 1st action mode, CPU
51 send control signals to pressure control portion 43 according to the 2nd action mode, and pressure control portion 43 is made to control supply electromagnetism
Valve 5 and electromagnetic valve for air discharge 6.Actuation means 1 maintain after operating pressure is gently increased to 2kPa from 0kPa as a result,
2kPa.Therefore, the valve opening of actuation means 1 becomes slightly opening state from completely closed state, does not overshoot.
In addition, for example, CPU 51 makees preset numbers " P3 " when user specifies preset numbers " P3 " via operation portion 35
For actual parameter, the 3rd action mode shown in Fig. 7 is read from EEPROM 54.Identically as above-mentioned 1st action mode, CPU
51 send control signals to pressure control portion 43 according to the 3rd action mode, and pressure control portion 43 is made to control supply solenoid valve 5
With electromagnetic valve for air discharge 6.When the operating pressure of actuation means 1 is adjusted to 2.5kPa first as a result, which is maintained 5
Second, then, after being decompressed to 2kPa, maintain the 2kPa.Therefore, the valve opening of actuation means 1 becomes slightly from intermediate opening state
Opening state does not overshoot.
In addition, for example, CPU 51 makees preset numbers " P4 " when user specifies preset numbers " P4 " via operation portion 35
For actual parameter, the 4th action mode shown in Fig. 8 is read from EEPROM 54.Identically as above-mentioned 1st action mode, CPU
51 send control signals to pressure control portion 43 according to the 4th action mode, and pressure control portion 43 is made to control supply solenoid valve 5
With electromagnetic valve for air discharge 6.When the operating pressure of actuation means 1 is adjusted to 5kPa first as a result, by 5kPa maintenance 5 seconds, so
Afterwards, after being decompressed to 2kPa from 5kPa within 2 seconds, the 2kPa is maintained.Therefore, the valve opening of actuation means 1 becomes from full open position
For slightly opening state, do not overshoot.
It should be noted that action mode can not only be specified by operation portion 35, can also be specified by host controller 9.
For the control process, it is illustrated while flow chart shown in 3 referring to Fig.1.Figure 13 is indicated using host controller
The flow chart of control process when work.The CPU 51 of control device 3 using from host controller 9 input preset numbers as opportunity,
It executes and is controlled shown in Figure 13.
CPU 51 will be stored from the preset numbers that host controller 9 receives into RAM 53 via communication interface part 42,
Thus preset numbers (S41) is received.Then, when there are preset numbers consistent with received preset numbers in CPU 51
(S42: yes) reads its action mode (S43) from EEPROM 54, starts the control (S44) of the operating pressure of cylinder 17.Separately
When on the one hand, without consistent preset numbers (S42: no), CPU51 carries out error notification (S45).The processing of S42~S45 and figure
9 S21~S23, S25 is identical, and and the description is omitted.It should be noted that the processing of S41~S43 is at action mode reading
An example of reason.The processing of S44 is an example of control processing.
As described above, preset numbers of the actuation means 1 via 9 required movement mode of operation portion 35 or host controller
Afterwards, control device 3 is just read from the multiple action modes being stored in EEPROM 54 corresponding with specified preset numbers
Action mode, and valve control (control of the operating pressure of cylinder 17) is carried out according to read action mode.Therefore, actuating dress
1 is set since valve opening is fed forward control, so will not overshoot in valve opening control, the response time can be shortened.In addition,
The pressure sensor for detecting the second pressure of actuation means 1 to control the valve opening of actuation means 1 becomes not needing, because
This, is simplified for controlling the control structure of valve opening of actuation means 1, becomes compact.
In addition, sluggishness can occur in valve opening movement and between when valve closing movement, increasing valve opening in actuation means 1
When and reduce valve opening when, valve opening corresponding from operating pressure is different.Therefore, the CPU 51 of control device 3 is in regulating valve
When aperture, keep the moving direction of piston 19 constant.That is, the CPU 51 of control device 3 is according to the 3rd movement mould for example shown in Fig. 7
When formula makes valve opening become small opening state from intermediate opening state, the operating pressure for making cylinder 17 is become to compare goal pressure
The control signal for rising to goal pressure Pe (2kPa) after Pe (2kPa) is small again is sent to pressure control portion 43.Actuating dress as a result,
It sets 1 always to pressurize to piston 19 along the valve opening position for leaving diaphragm 16 from valve seat 14, thus makes the operation of cylinder 17
Pressure is consistent with goal pressure Pe.Therefore, actuation means 1, which can be avoided, causes because of sluggishness even if in same operation pressure lower valve
Also different situation, precision are excellent for aperture.
(use example)
Next, the use example for actuation means 1 is illustrated.Figure 14 is an example for indicating medical supplies production line
Figure.Feeding pipe 62 is connected to the upper surface of tank body 61, and is configured with the 1st actuation means 1A.Discharge line 63 and tank body 61
Lower surface connection.Discharge line 63 is successively equipped with the 2nd actuation means 1B, filter 64 and the 3rd actuation means from 61 side of tank body
1C.Gas exhaust piping 65 is connected to the top of filter 64, and is equipped with the 4th actuation means 1D.
1st actuation means~the 4th actuation means 1A~1D has structure identical with above-mentioned actuation means 1.1st actuating dress
It sets in~the 4 actuation means 1A~1D according to using purpose to be stored with action mode.
For example, being stored with the 1st action mode shown in fig. 5 in the 1st actuation means 1A.It is deposited in the 2nd actuation means 1B
Contain the 1st action mode shown in fig. 5.The 3rd action mode shown in Fig. 7 is stored in the 3rd actuation means 1C.Also,
The 2nd action mode shown in fig. 6 and the 4th action mode shown in Fig. 8 are stored in 4th actuation means 1D.Herein, the 1st movement
Mode~the 4th action mode preset numbers are general, but can also be different for each valve.
Host controller 9 supplies 5 seconds in order to ensure health and by the hot water of high temperature into pipeline, thus implements to tank body 61
CIP (cleans on the spot: Cleaning In Place), then the steam of high temperature being supplied in pipeline, implement SIP to tank body 61
It (sterilizes on the spot: Sterilizing In Place).
At this point, host controller 9 sends preset numbers " P1 " to the 1st actuation means 1A and the 2nd actuation means 1B, to the 3rd
Actuation means 1C sends preset numbers " P3 ", sends preset numbers " P4 " to the 4th actuation means 1D.
As a result, during the hot water of high temperature is flowed from feeding pipe 62 to tank body 61, discharge line 63, the 3rd actuating dress
The valve opening for setting 1C is controlled in intermediate opening state, while the valve opening of the 4th actuation means 1D is controlled in and fully opens shape
State.Therefore, air is discharged via the 4th actuation means 1D, hot water, with flow at high speed, can be improved cleaning effect in pipeline.
After supplying hot water 5 seconds to tank body 61, steam is supplied to tank body 61.Steam from feeding pipe 62 to tank body 61,
During discharge line 63 flows, the valve opening of the 3rd actuation means 1C and the 4th actuation means 1D are reduced to slightly opening state.
Thereby, it is possible to while inhibiting steam discharge as much as possible, it is ensured that steam flowing improves sterilizing efficiency.At this point, the 4th actuating
Device 1D gently reduces valve opening, and therefore, the internal pressure for being able to suppress filter 64 sharply increases.
It should be noted that host controller 9 when carrying out CIP and SIP after replacing filter 64, is filled for the 4th actuating
It sets 1D and supplies preset numbers " P2 ", rather than preset numbers " P4 ".The 4th actuation means 1D is gently from completely closing shape as a result,
State becomes slightly opening state, gently the air in discharge filter.When therefore, can be avoided filter because of injection hot water
Pressure and it is damaged.
