It can be connected to a programmable logic system (PLC) via the / O connector 12.

Before describing the details of the static elimination monitor 1,
Explaining the static elimination bar unit 2, the static elimination bar unit 2 is composed of, for example, a pulse AC type static elimination bar shown in a block diagram in FIG. Static elimination bar unit 2 shown in FIG.
Includes positive and negative high voltage generation circuits 201 and 202, and high voltages are alternately supplied to the electrode needles 203 from the positive and negative high voltage generation circuits 201 and 202. The electrode needles 203 cause ions of different polarities, that is, positive and negative. Ions are alternately generated.

The positive and negative high voltage generating circuits 201 and 202 are
Both are self-excited oscillation circuit 206 connected to the primary side coils of transformers 204 and 205, and connected to a secondary coil.
For example, the booster circuit 207 including a double rectifier circuit is included. A protective resistor 209 is provided between the high voltage generation circuits 201 and 202 and the electrode needle 203.

A ground (GND) plate 210 is provided near or around the electrode needle 203, and this GND plate 210 is connected to a work side ground, that is, a frame ground FG through a conductor 211, and a conductor 211.
Is provided with _first and _second resistors R ₁ and R ₂ in series. Specifically, the first resistor R ₁ is the GND plate 21.
The second resistor R ₂ provided on the 0 side is connected to the frame ground F
It is provided on the G side. The positive and negative transformers 204 and 20 are connected between the first resistor R ₁ and the second resistor R _2.
The ground side end of the secondary coil of No. 5 is connected by the conductor 212.

Between the electrode needle 203 and the GND plate 210
Current I between₁Is the first resistance R₁Potential difference V₁By
It can be detected directly. Also, the frame on the work side
The difference between the amount of positive and negative ions reaching the mugland FG is
Second resistor R_TwoCurrent I through _TwoThat is, the second resistance R_Twoof
Potential difference V_TwoCan be indirectly detected by.

Therefore, the potential difference V _{1 of the first} resistor R ₁
The degree of discharge by the electrode needle 203, that is, the amount of ions generated by the electrode needle 203 can be detected by this, and not only can the performance or efficiency of the electrode needle 203 be reduced, but also the electrode needle 203 can be detected. It is possible to know the balance between the positive and negative ion generation amounts generated by.
On the other hand, the work charge state, that is, the ion balance can be known from the potential difference V _{2 of} the second resistor R ₂ .

For example, the potential difference V ₁ of the first resistor R ₁ is detected by the ion current detection circuit 214, and the detection data is input to the CPU 215 so that the CPU 215 can maintain the work charge state, that is, the ion balance. By controlling the positive and negative self-excited oscillation circuits 206 and 207 in order to change the positive and / or negative supply voltage to the electrode needle 203 or change the pulse width, the balance between the positive and negative ion generation amounts is made constant. Can be maintained (ICC control).

Further, when the potential difference V _{1 of} the first resistor R ₁ is extremely small or becomes small with time and becomes smaller than a threshold value, for example, it means that an abnormal discharge has occurred, and the alarm means or the display means 216 indicates. You may make it notify a worker. An example of this type of discharge abnormality is when dust is deposited on the electrode needle 203.

Further, for example, the potential difference V of the second resistor R _2
2 is detected by the ion current detection circuit 214, this detection data is input to the CPU 215, and the positive and / or negative supply voltage to the electrode needle 203 is changed so that the work charge state, that is, the ion balance can be maintained. Alternatively, the pulse width may be changed (ion balance control). In addition to this, the fact that the ion balance is not maintained may be notified to the operator through the alarm means or the display means 216.

Further, for example, the potential difference V of the first resistor R _1
When the potential difference V ₂ between the _first and / or second resistor R ₂ is extremely large, this is detected by the abnormal discharge current detection circuit 217 and input to the CPU 215. For example, the electrode needles 203 and G
Since a short circuit has occurred between the ND plate 210 and between the electrode needle 203 and the work and an abnormal discharge has been generated, the alarm means or the display means 216 causes an alarm such as turning on an emergency light or sounding an alarm sound. To a user or an operator, and by incorporating a switch in the positive and negative self-excited oscillation circuits 206 and 207 and cutting the switch, the operation of the static elimination bar unit 2 is forcibly stopped. You may do it.

By detecting the potential difference V ₁ of the first resistor R ₁ with the ion current detection circuit 214, it is assumed that the electrode needle 203 is contaminated or contaminated.
A display to that effect can be displayed on the ED 216. Also,
Positive side current value I ₁ or I ₂ and negative side current value I ₁ or I ₂
By comparing with, it is possible to know the balance of the amount of generated ions.

When the first display mode of FIG. 4 is selected, the (+) or (-) side LED emits light in accordance with the charge amount on the positive side or the negative side of the work. As the ion balance approaches zero, any one of the central LEDs 223 to 225 emits green light, and finally the central LED 224 emits green light to indicate that the neutralization is completed. . As can be easily understood by those skilled in the art, such a display mode is used for each of the LEDs 221 to 227.
This can be carried out by preparing "threshold values" for emitting light and comparing these "threshold values" with the detected values.

This "alarm confirmation" character indicates that the current screen is the unit alarm confirmation mode 303. The character "ALL" at the upper left of FIG. 9 means that it is the alarm confirmation display for all units. When no alarm is issued to all the units 2 connected to the monitor 1, the message "No alarm" is displayed (Fig. 11).

If there is a unit 2 for which an alarm is issued, the display is as shown in FIG. To explain the display of FIG. 12, "BAR0" is "I".
D-0 ”means unit 2 and“ BAR1 ”means“ ID-
1 ”means unit 2.

The word "condition alarm" on the right side of the "ID-0" unit 2 as shown in FIG. 12 indicates, for example, that the charged state of the work is at the alarm level, specifically, shown in FIG. It means that the ion current detection circuit 214 has some problem that the static elimination performance of the unit 2 cannot be maintained such that a larger current than the normal current is generated. Also, as shown in the figure, "ion level alarm" on the right side of the "ID-1" unit 2

When an alarm is issued to the monitoring monitor 1 or unit 2, the monitoring monitor 1 or all units 2 at that time
It is preferable to save the operating status and alarm contents of the above in the internal memory.

(7) Unit alarm notification 308: The monitoring monitor 1 constantly monitors the abnormality of all the static elimination bar units 2 connected, that is, the alarm generation state, and immediately when a problem occurs in any of the units 2, As the alarm notification, the unit alarm notification 308 is switched to, and the screen (FIG. 18) of the unit alarm notification 308 is displayed on the monitor 1
It is displayed on the CD display unit 3. That is, when an alarm occurs in any of the units 2, the screen of the LCD display unit 3 is automatically switched to the screen of the unit alarm notification 308 (FIG. 18), and preferably the display screen is displayed by blinking. Call attention to.

Further, one of the four LEDs 5 provided on the monitor 1 in synchronization with the display of the alarm screen is constituted by a red LED for alarm, and the LED for alarm is turned on or blinks, and / or In response to the request, the monitoring monitor 1 may be provided with a unit such as a buzzer for emitting an alarm sound, and the alarm sound may be emitted in synchronization with the display of the alarm screen. The alarm relating to the unit 2 includes at least the following items.

Communication error alarm: A communication error has occurred between the monitor 1 and each unit 2.

Device failure alarm: The operating state of the unit 2 cannot be grasped due to a failure of a device of each unit 2, for example, an EEPROM.

Abnormal discharge alarm: An abnormal discharge has occurred in each unit 2.

Condition alarm: For example, in the ion current detection circuit 214 shown in FIG. 3, a current larger than the normal current is generated, and each unit 2 cannot maintain the original static elimination performance. .

Ion level alarm: The ion generation amount of each unit 2 is below the threshold value. Note that this threshold is set in the unit setting mode 3 as already described.
It can be set by the operator using 06 (FIG. 16).

Regarding the display of these six types of alarm notifications, when the alarms are duplicated, the priority order for determining which alarm is to be preferentially displayed is three levels from level 1 to level 3 for each alarm. It is set.

As can be understood from the list below, level 1 includes a communication error alarm, equipment failure alarm, abnormal discharge alarm, level 2 includes a condition alarm, and level 3
Includes an ion level alarm. For example, when the level 1 and level 2 alarms are in conflict with each other, the level 1 alarm is preferentially displayed, and the level 2 alarm display is suspended.

Level 1 (Priority: High): Communication error alarm, device failure alarm, abnormal discharge alarm Level 2 (Priority: Medium): Condition alarm Level 3 (Priority: Low): Ion level alarm

Levels 1 to 3 are classified according to the size of the problem in the operation of the static elimination bar unit 2.
Level 1 is a problem that cannot be ignored in the operation of the unit 2. When this level 1 alarm is issued, the communication relationship between the static elimination bar unit 2 and the monitoring unit 1 that issued the level 1 alarm is canceled. It Specifically, the ID for identifying the unit 2 is removed from the unit 2, so that the communication between the unit 2 and the monitor 1 is disabled or blocked. Regarding the level 1 alarm, when a device failure or abnormal discharge occurs, the static elimination operation of the unit 2 is stopped by the internal control of the unit 2 itself.

Levels 2 and 3 are considered to have relatively small problems in the operation of unit 2. When level 2 and level 3 are compared, the level 2 condition alarm is issued when the static elimination performance cannot be maintained, and therefore has a higher priority than the level 3 ion level alarm.

When the level 1 to level 3 alarms conflict with each other, as a rule for determining the order of displaying the alarms, for example, when a plurality of alarms are generated in different units 2, a high priority alarm is issued. Unit 2 is the alarm output unit. When a plurality of alarms having the same priority order are generated in different units 2 with a time lag, the unit 2 having a first alarm is set as the alarm output unit. When multiple alarms with the same priority are simultaneously generated in different units 2, the unit 2 with the smaller unit ID
Is the alarm output unit. When the alarm output unit simultaneously outputs two or more types of alarms, the alarm screen 308 is displayed because the alarm with the higher priority is generated.

As for the level 1 to 3 alarm display, by pressing the return key SW9, as shown in FIG.
When the screen is switched to the screen that displays "Please refer to the troubleshooting in the instruction manual" and the operator who confirms this screen presses the return key SW9 again, the original normal screen is restored. Normally, the operator would follow the screen and retrieve the instruction manual and refer to it to solve the problem occurring in the indicated unit 2.

(8) Main unit abnormality mode 309: The monitor 1 constantly monitors its own current consumption, internal temperature, etc., and when an abnormality is found, immediately displays a screen of this main unit abnormality mode 309 as an alarm notification. (Fig. 19),
The screen of the main body abnormality mode 309 is displayed on the LCD display unit 3 of the monitor 1, and at the same time, the power supply to all the units 2 is stopped. That is, when a problem occurs inside the monitor monitor 1, the screen of the LCD display unit 3 is automatically switched to the screen of the main body abnormality mode 309 (FIG. 19),
Preferably, the display screen is displayed in a blinking manner to alert the operator and stop the power supply to all the units 2.

Further, in synchronization with the display of the alarm screen, one of the four LEDs 5 provided on the monitor 1 is composed of a red LED for alarm, and the LED for alarm is turned on or blinked, and / or In response to the request, the monitoring monitor 1 may be provided with a unit such as a buzzer for emitting an alarm sound, and the alarm sound may be emitted in synchronization with the display of the alarm screen. The alarm relating to the monitor 1 includes at least the following items.

High temperature alarm inside the main body: In order to protect the monitor 1, the internal temperature of the monitor 1 is detected by a temperature sensor, and this internal temperature is equal to or higher than a threshold value (specification temperature or higher).
When the air-cooling fan fails and stops, or when the air-cooling ventilation part is blocked and if left unattended, the inside of the monitor 1 may become hot. When the above problem occurs, this internal high temperature alarm is issued.

Main body overcurrent detection alarm: In order to prevent the monitor 1 from malfunctioning, this main body overcurrent detection alarm is issued when an overcurrent occurs in the internal wiring of the monitor 1. For example, when a predetermined number or more of units 2 are connected, or when a cable for supplying power from the monitor 1 to the unit 2 is disconnected and the power supply line to the unit 2 is short-circuited, the main body overcurrent detection alarm is issued. To be

Main body abnormality "0" alarm: This main body abnormality "0" is issued when communication from the monitoring monitor 1 to the static elimination bar unit 2 is impossible.

Main body abnormality "1" alarm: This main body abnormality "1" is issued when the contents of the internal memory of the monitor 1 are destroyed, for example, when the battery runs out, or when the internal memory itself is destroyed.

Main unit abnormality mode 3 including the above four alarms
09 has a higher priority than the unit alarm notification 308 described above, and when it conflicts with the six types of alarm notifications included in the unit alarm notification 308, the main body abnormality mode 309 is preferentially entered.

To get rid of the above alarms,
It is possible to return to the normal screen by restarting the monitor 1 after the operator removes the cause by turning off the power of the monitor 1.

20 to 26 show a unit alarm notification 30.
8 illustrates a timing chart of alarm output regarding the main body abnormality mode 309.

FIG. 20 relates to the main body abnormal mode 309. When an alarm is issued to the monitor monitor 1, even if the level 1 to 3 other unit alarm notifications 308 are issued, the main body abnormal mode is immediately issued. Enter 309,
Switch to the screen of this main unit abnormality mode 309,
In synchronization with this, the LED 5 blinks in red. The operator turns off the power of the monitor 1, removes the problem, that is, the cause of the alarm of the monitor 1, and then turns on the power of the monitor 1 again to return to the normal operation.

FIG. 21 is a timing chart when a level 1 alarm is issued to a different unit 2 during a level 2 alarm (condition alarm) of the unit alarm notification 308. As can be understood from the figure, at the same time as the subsequent level 1 alarm, the condition alarm (level 2 alarm) screen is switched to the corresponding level 1 alarm screen. When the operator detects that the operator has confirmed the key operation, the user exits the level 1 warning screen and switches to the start condition warning screen.

The LED 5 provided on the monitor 1 lights up in red in synchronization with the condition alarm (level 2 alarm) screen, and blinks in red in synchronization with the level 1 alarm screen. The LED 5 is turned off by solving the problem of the corresponding unit 2. This allows the operator to LE
It is possible to confirm that the difference between the alarms generated in the unit 2 and the problem have been resolved by lighting or blinking D5.

When the monitor 1 detects that a level 1 alarm has been generated, the monitor 1 releases the communication relationship with the corresponding unit 2 (removes the ID) in synchronization with this. When the operator confirms the level 1 alarm notification screen and performs a confirmation operation of pressing down the return key SW9, the level 1 alarm notification screen is switched to the level 2 alarm notification screen. This level 2
The alarm notification screen of No. disappears when the operator performs a confirmation operation of pressing the return key SW9, and the screen returns to the normal screen. The fact that the alarm notification screen is switched by pressing the return key SW9 is the same in the following various cases. This makes it possible to effectively use the display unit 3 having a limited size to display a plurality of conflicting alarms.

When the static elimination state of the static elimination bar unit 2 exceeds the alarm level and detects level 1 where the original static elimination function cannot be exerted, the monitoring monitor 1 immediately releases the communication relationship with the corresponding static elimination bar unit 2, so that a plurality of When there is a conflict with the above alarms, after confirming the level 1 alarm notification screen with higher priority, when another alarm screen is operated to exit from the alarm screen, the level 1 alarm screen appears again. It is possible to prevent it.

In this case, the first level 1 alarm display is continued without being affected by another subsequent level 1 alarm generation, and when it is detected that the operator has confirmed the key operation by the operator, Immediately after switching off the first level 1 alarm display, the display immediately switches to the later level 1 alarm display.

The LED 5 provided on the monitor 1 blinks red in synchronization with the level 1 alarm screen, and continues to blink red until the level 1 alarm ends.

FIG. 23 is a timing chart when a level 3 alarm (ion level alarm) is generated in a different unit 2 while a level 2 alarm (condition alarm) of the unit alarm notification 308 is being generated. In this case, the display of the first level 2 alarm (condition alarm) is continued without being affected by the generation of another subsequent level 1 alarm, and the operator confirms the key operation by the operator. Is detected, the warning display of the level 2 of the starter is removed, and immediately the display of the level 3 (ion level alarm) of the starter is switched.
