Description

  The present invention relates to a static eliminator, and more particularly to an improvement in a static eliminator that takes in air from the outside and generates humidified air.

  The static eliminator is an apparatus that removes excess electricity from a workpiece by supplying static-removed ions having a reverse polarity to the workpiece charged by static electricity. For example, static elimination ions are generated by ionizing air using corona discharge by an electrode needle to which a voltage is applied, and are composed of positive ions or negative ions.

  Moreover, there exists a type of static elimination apparatus which diffuses static elimination ion by blowing air from the air blowing port of a head unit (for example, patent document 1). The head unit is provided with electrode needles, and air is supplied from the air supply unit. According to this type of static eliminator, since static elimination ions are transported in the air blowing direction, it is possible to eliminate static electricity even at a farther workpiece. Further, since the static elimination ions are promptly conveyed to the position of the workpiece, the time required for static elimination of the workpiece can be shortened.

  Furthermore, a neutralization device with a humidifier has been proposed that diffuses neutralization ions by blowing out humidified air composed of air containing water vapor. The humidified air is generated when the air heated by the heater passes through a humidifying filter containing water. The humidified air that has passed through the humidifying filter is guided to the suction port of the fan blower through a communication path that is blocked from the outside by a partition wall. According to such a static eliminator with a humidifier, the work and surrounding devices are less likely to be charged by humidification, so that the static elimination effect can be enhanced.

  The above-described static eliminator with a humidifier detects the temperature of humidified air that has passed through the humidifying filter using a temperature sensor disposed near the suction port of the fan blower, and adjusts the temperature of the heater using the detection result. Thus, the humidity control of the humidified air is performed. However, the air heated by the heater has temperature unevenness, and the humidified air immediately after passing through the humidifying filter is composed of relatively warm humidified air and cold humidified air. For this reason, in the static eliminator with a humidifier described above, the absolute humidity of the humidified air in the vicinity of the suction port becomes spatially nonuniform, and the absolute humidity of the humidified air blown from the air outlet of the head unit becomes a desired value.

Is done. According to such a configuration, since the humidified air that has passed through the throttle opening of the throttle partition is guided to the suction port side of the fan blower by the duct, the absolute humidity of the humidified air near the suction port can be made more uniform. .

The float unit 124 is disposed in the water receiving tray unit 42. The sensing unit 125 is a position detection unit that detects the vertical position of the float unit 124 and outputs a detection signal. The sensing unit 125 is disposed in the main body housing 40 and can detect the presence or absence of the water receiving tray unit 42.

  For example, a magnet is fixed to the float part 124, and the sensing part 125 is comprised by the Hall element which detects the position of the said magnet using a Hall effect. In the sensing unit 125, a plurality of Hall elements are arranged at different positions in the vertical direction. For example, by providing three Hall elements, it is possible to detect whether the water level falls within the limit area, the appropriate area, or the water supply area, and the presence or absence of the water receiving tray section 42.

  The limit area is a range that exceeds a predetermined determination threshold L1 and indicates that the amount of water in the water receiving tray section 42 is excessive. The water supply area consists of a range that falls below a predetermined determination threshold L2 (L2 <L1), and indicates that the amount of water in the water receiving tray section 42 is insufficient. The appropriate range is a range of L2 or more and L1 or less, and indicates that the amount of water in the water receiving tray section 42 is an appropriate amount.

<Water receiving tray section 42>
FIG. 8 is a diagram illustrating a configuration example of the controller 4 of FIG. 3, and shows a cut surface when the main body housing 40 is cut by a horizontal plane passing through the water receiving tray portion 42. Of the side walls of the water receiving tray portion 42, the side wall exposed from the main body housing 40 is a double wall constituted by an outer wall 42b and an inner wall 42c.

  The inner wall 42 c is a partition wall that surrounds the storage portion that stores the lower portion of the water storage tank portion 41. The outer wall 42b is formed so as to surround the inner wall 42c. The housing portion of the water receiving tray portion 42 is provided with a protruding portion 42d for pushing the water supply valve of the water storage tank portion 41 and allowing water to flow out.

  The protrusion 42 d pushes the water supply valve of the water storage tank unit 41, so that water is supplied from the water storage tank unit 41 to the water receiving tray unit 42. If the water level of the water receiving tray part 42 exceeds the position of the water supply valve, air is not supplied to the water storage tank part 41, and the outflow of water automatically stops. The lower portion of the main body housing 40 is a housing portion that houses the water receiving tray portion 42, and the left and right side walls of the housing portion are also made of double walls similar to the water receiving tray portion 42.

  By adopting such a double wall structure, the inner wall 42c can be prevented from being damaged by an external impact, and the water in the water receiving tray 42 can be prevented from being damaged even if the outer wall 42b is damaged. It is possible to prevent leakage to the outside.

  FIG. 9 is a perspective view showing a configuration example of the controller 4 in FIG. 3, and shows the back surface of the main body housing 40. On the back surface of the main body housing 40, a drain port 5, an outside air sensor 103, and a terminal block 104 are disposed.

  The terminal block 104 is a signal cable connection part, and various signals are input and output. For example, a water level signal indicating the water level and an alarm signal informing the maintenance timing are output. The drain port 5 is a drain for discharging water in the water receiving tray part 42, and is disposed at the lower end of the main body housing 40. The outside air sensor 103 is a detector for detecting the temperature of outside air near the main body housing 40.

  Based on the output of the water level sensor 123, the water level signal is generated by identifying whether the water level in the water receiving tray section 42 corresponds to a limit area, an appropriate area, or a water supply area. Such a water level signal is an open / close control that opens or closes an electromagnetic valve that opens and closes a water tap for supplying water to the main body housing 40 when the static elimination device 1 is a static elimination device with a humidifier. Can be used.

  The alarm signal is obtained by detecting the presence / absence of the water receiving tray unit 42 and forgetting to put in the humidifying filter 121 based on the outputs of the water level sensor 123, the outside air sensor 103, and the air detecting unit 131 and the operating state of the heater 111. Generated. The presence / absence of the water receiving tray 42 is detected based on the output of the water level sensor 123. Forgetting to put in the humidifying filter 121 is detected by comparing the outside air temperature when the heater 111 is in the off state with the temperature of the humidified air by the air detection unit 131, and whether or not a temperature decrease due to absorption of vaporization heat is observed. .

  The alarm signal is generated by detecting the clogging of the humidifying filter 121 and the contamination of the electrode needle 21 based on the outputs of the water level sensor 123 and timer (not shown) and the operating state of the fan blower 101. The That is, the humidification filter 121 is detected by comparing the water level when the fan blower 101 is in the off state and the water level when the fan blower 101 is in the on state, and whether or not the water level is increased. The contamination of the electrode needle 21 is detected by a decrease in ion current.

<Interface unit 105>
FIG. 10 is a diagram showing an example of a detailed configuration of the interface unit 105 of FIG. The interface unit 105 includes an indicator unit 61, a status display unit 62, numerical display units 63 and 64, an operation button 65, a mode button 66, and selection buttons 67 and 68.

  The indicator unit 61 is a display unit 106 that notifies the operation state of the controller 4, the amount of water in the controller 4, and the maintenance time by the lighting state and lighting color of the indicator. The indicator unit 61 includes an operation indicator, a water level indicator, and a maintenance indicator.

  The operation indicator lights green during normal operation and lights red when stopped. When an abnormality occurs, it flashes red. For example, if an abnormality such as water leakage, poor attachment of the water receiving tray section 42, poor connection of cables, abnormal discharge at the tip of the electrode needle, tipping of the controller 4 or circuit failure occurs, the operation indicator blinks red. When such an abnormality occurs, an alarm signal is output from the terminal block 104, and the operation of the controller 4 is stopped.

  The water level indicator lights orange when the water level of the water receiving tray section 42 is lowered, otherwise it lights green during operation, and turns off when stopped. The maintenance indicator lights red when the humidification performance decreases, and lights orange when the ion generation amount decreases. When both the humidification performance and the amount of generated ions are reduced, the light blinks red. When the humidification performance decreases, a humidification alarm signal is output from the terminal block 104. Further, when the ion generation amount decreases, an ion level alarm signal is output from the terminal block 104. Further, when both the humidification performance and the ion generation amount are reduced, a humidification alarm signal and an ion level alarm signal are output from the terminal block 104.

  The state display unit 62 is a display unit 106 that displays any one of the relative humidity of the humidified air, the air volume of the fan blower 101, and the charge amount of the object as a bar. The status display unit 62 selectively lights up seven indicators arranged on a straight line extending in the left-right direction, thereby displaying the relative humidity, the air volume, and the charge amount according to the length of the bar. The sign is displayed according to the bar position. The lower limit indicates relative humidity = 30%, and the upper limit indicates a target relative humidity.

  The numerical display unit 63 is a display unit 106 that displays the ambient temperature of the head unit 2 as a numerical value, and displays the temperature detected by the outside air sensor 103. The numerical value display unit 64 is a display unit 106 that displays a target relative humidity numerically.

  The operation button 65 is an operation unit 107 for starting the operation of the controller 4 or stopping the controller 4 during operation. The mode button 66 is an operation unit 107 for switching a display target of the state display unit 62 and an adjustment target by the selection buttons 67 and 68. By operating the mode button 66, the display target can be changed among the relative humidity, the air volume, and the charge amount. Further, by operating the mode button 66, the adjustment target can be changed among the relative humidity, the air volume, and the ion balance.

  The selection buttons 67 and 68 are the operation unit 107 for adjusting the target relative humidity, the air volume of the fan blower 101, and the ion balance. The selection button 67 is an increment button for increasing the relative humidity and the air volume. The selection button 68 is a decrement button for decreasing the relative humidity and the air volume. The ion balance is a generation ratio of positive ions and negative ions, and can be adjusted by operating the selection button 67 or 68.

  By operating the mode button 66, the operation mode can be switched from the operation mode to the setting mode for setting various parameters. In the setting mode, the setting items can be changed by operating the selection buttons 67 and 68.

  For example, when the ionized air generation unit is driven by a pulse AC or pulse DC that alternately outputs positive ions and negative ions, a positive and negative switching frequency can be set.

  In addition, a threshold value for determining whether or not to output an ion level alarm signal can be set. In accordance with the input of a stop signal from an external device, it is possible to select whether the function for stopping static elimination is valid or invalid. When the function of stopping static elimination is activated, if a stop signal is input to the terminal block 104 from an external device, the generation of ions is stopped by stopping the application of voltage to the electrode needle 21.

  Further, it is possible to select whether the function of stopping the heater 111 is valid or invalid in response to a stop signal input from an external device. When the function of stopping the heater 111 is validated, the function of the heater 111 is stopped if a stop signal is input to the terminal block 104 from an external device. The stop signal input terminal for stopping static elimination and the stop signal input terminal for stopping the heater function may be provided separately on the terminal block 104 or may be shared.

  Furthermore, in order not to blow a minute object by air, the validity or invalidity of the light wind mode that minimizes the air volume of the fan blower 101 can be selected. If the light wind mode is enabled, the air volume of the fan blower 101 cannot be adjusted by the selection button 67 or 68. The air volume in the light air mode may be the minimum air volume that can be selected in the normal time, or may be smaller than the minimum air volume that can be selected in the normal time.

  In addition, it is possible to select whether the power-on automatic start function is valid or invalid. If the power-on N automatic start function is disabled, the static eliminator 1 is started in a stopped state, and the operation of the controller 4 is started when the operation button 65 is pressed. On the other hand, if the power-on automatic start function is validated, the operation starts even if the operation button 65 is not pressed. Further, the signal output from the terminal block 104 can be forcibly shifted to the on state or the off state. Thereby, in the apparatus connected to the terminal block 104, the wiring connection state can be confirmed.

<Terminal block 104>
FIG. 11 is a diagram showing an example of a detailed configuration of the terminal block 104 of FIG. The terminal block 104 includes three input terminals T1 to T3 and four output terminals T4 to T7. The input terminal T1 is a ground terminal on the input side. A static elimination stop signal or a heater stop signal is input to the input terminal T2. An operation stop signal for stopping the operation of the controller 4 is input to the input terminal T3.

  The output terminal T4 is an output-side ground terminal. The output terminal T5 outputs an ion level alarm signal or a humidification alarm signal. The output terminal T6 outputs a water level alarm signal. The water level alarm signal is output when the water level in the water receiving tray section 42 is lowered. The output terminal T7 outputs an alarm signal.

  According to the present embodiment, the humidified air that has passed through the humidifying filter 121 is guided to the branch openings 52a and 52b at both ends of the deflecting unit 52 by the deflecting unit 52, and further, the humidified air that has passed through the branch openings 52a and 52b. Is guided to the diaphragm opening 53 a by the diaphragm partition 53. For this reason, since the humidified air is sufficiently stirred on the upstream side of the throttle opening 53a due to the collision between the humidified air passing through the branch openings 52a and 52b, the absolute humidity of the humidified air in the vicinity of the suction port 40d of the fan blower 101 is reduced. Spatial uniformity can be achieved.

  Further, since the humidified air that has passed through the throttle opening 53a of the throttle partition 53 is guided to the suction port 40d side of the fan blower 101 by the duct 54, the absolute humidity of the humidified air in the vicinity of the suction port 40d can be made more uniform. . Furthermore, the humidified air that has passed through the humidifying filter 121 is sufficiently stirred in the air mixing chamber 13 to reduce temperature unevenness. For this reason, the absolute humidity of the humidified air blown from the air outlet 23 of the head unit 2 is accurately determined by detecting the temperature of the humidified air in the vicinity of the inlet 40d of the fan blower 101 and adjusting the temperature of the heater 111. Can be controlled.

For example, a configuration in which only the deflection unit 52 and the throttle partition wall 53 are provided in the air mixing chamber 13 and the duct 54 is not provided may be employed. Further, the throttle partition may be arranged on the upstream side of the air flow path, and the deflection unit may be arranged on the downstream side of the air flow path. Even with such a configuration, the absolute humidity of the humidified air in the vicinity of the suction port 40d of the fan blower 101 can be made spatially uniform.

  Moreover, although this embodiment demonstrated the example of the static electricity removal apparatus with a tank attachment / detachment type humidifier with which the water storage tank part 41 was mounted | worn with the main body housing | casing 40, this invention is a static electricity removal apparatus with a pipe type humidifier. Can also be applied.

This static eliminator 1 is a pipe-type static eliminator with a humidifier. Compared with the static eliminator 1 shown in FIGS. 3 and 9, the controller 4 does not include the water storage tank part 41 and the water receiving tray part 42. It differs in that it has a mouth 6.

  In addition to the drain port 5, the outside air sensor 103 and the terminal block 104, a water supply port 6 is provided on the back surface of the main body housing 40. The water supply port 6 is a water injection port for supplying humidifying water into the main body housing 40, and is disposed in the middle stage of the main body housing 40. The humidification filter 121 and the water level sensor 123 are disposed in the main body housing 40.

  In the present embodiment, the example in which the air detection unit 131 detects the temperature of the humidified air in the air mixing chamber 13 has been described, but the present invention limits the configuration of the air detection unit 131 to this. is not. For example, the air detection unit 131 includes a temperature sensor and a humidity sensor, detects the temperature and relative humidity of the humidified air in the air mixing chamber 13, and controls the temperature adjustment unit 11 using the detection result. It may be a configuration. Moreover, the structure which the air detection part 131 detects the absolute humidity of the humidification air in the air mixing chamber 13, and controls the temperature adjustment part 11 using the detection result may be sufficient.

  In the present embodiment, an example in which any one of the relative humidity of the humidified air, the air volume of the fan blower 101, or the charge amount of the target object is displayed on the state display unit 62 as a bar is described. The configuration of the status display unit 62 is not limited to this. For example, a configuration in which the relative humidity of the humidified air, the air volume of the fan blower 101, and the charge amount of the object are simultaneously displayed in a bar may be used.

  Further, in the present embodiment, an example in which the interface unit 105 is disposed in the main body housing 40 has been described, but the present invention does not limit the configuration of the interface unit 105 to this. For example, the interface unit 105 may be detachably connected to the main body housing 40 via a wiring cable.
