Description

[Technical Field]

[0001] The present invention relates to a dispenser system for applying or filling a fluid such as a coating material or a filler material. [Background technology]

[0002] Conventionally, dispenser systems used for applying or filling a fluid have been provided. For example, a coating system capable of performing a coating operation of applying a coating material to a coating target (workpiece) and a filling system capable of performing a filling operation of filling a filling target (workpiece) with a filler material have been proposed as dispenser systems used for applying or filling a fluid (see, for example, Patent Document 1).

[0003] The above-mentioned Patent Document 1 discloses a pattern forming device that discharges a paste-like pattern forming material (coating material) from the discharge port of a nozzle to form a pattern on a substrate as a coating target. This Patent Document 1 describes that it is possible to form a pattern having a predetermined pitch and cross-sectional shape (pattern height, width, etc.), as well as to form a pattern with a modified predetermined pitch and cross-sectional shape.

[0004] Furthermore, Patent Document 1 discloses that by inputting values ​​for the desired pattern pitch and cross-sectional shape, such as "pitch 300 μm, width 80 μm, height 150 μm," multiple parameters that determine the output to the motor, pump, light source unit, etc. Patent Document 1 also discloses that the coating pattern is controlled mainly by adjusting the nozzle angle of the discharge port, the relative movement speed between the workpiece and the nozzle, UV irradiance, etc. However, Patent Document 1 does not disclose in detail how the amount of pattern formation material (coating material) discharged from the pump is controlled. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4082499 Summary of the Invention [Problem to be solved by the invention]

[0006] Generally, as described in Patent Document 1, users manage the amount of coating material applied by coating dimensions (coating shape) such as coating diameter and height. On the other hand, the parameters set in a control device (controller) that controls the operation of a coating system are mostly the rotation speed of a pump, the flow rate of the coating material, the coating amount, and the coating time. Detailed calculations and know-how are required to set and adjust the parameters to obtain the desired coating dimensions for a coating pattern.

[0007] As an example of a pattern forming device, when a dispenser device is used in a coating system, the dispenser device performs a discharge operation in which the pump mechanism is operated to move the coating material from the pump mechanism toward the discharge port, thereby discharging the coating material, and a suck-back operation (reverse suction operation) in which the pump mechanism is operated to move the coating material from the discharge port toward the pump mechanism, thereby sucking the coating material. By performing reverse suction when the device is stopped, residual pressure in the nozzle is eliminated, preventing dripping. However, setting the reverse suction operation is not easy. Specifically, when adjusting the coating amount, changing the rotation speed of the pump mechanism changes the flow rate of the coating material, which changes the discharge pressure and, therefore, the optimal reverse suction setting. Therefore, changing the reverse suction setting also changes the coating amount of the coating material. This poses the problem of requiring repeated adjustments to obtain the desired amount of coating material applied to the coating target.

[0008] Furthermore, even when the dispenser device described above is used in a filling system, reverse suction is performed when the device is stopped to eliminate residual pressure in the nozzle and prevent dripping. However, as with the case where the dispenser device is used in a coating system, setting the reverse suction is not easy. Specifically, when adjusting the filling amount, if the rotation speed of the pump mechanism is changed, the flow rate of the filler material changes, which in turn changes the discharge pressure, resulting in a change in the optimal reverse suction setting. Therefore, if the reverse suction setting is changed, the filling amount of the filler material also changes. This poses the problem of having to make adjustments multiple times until the desired amount of filler material is filled into the workpiece.

[0009] The present invention has been made to solve the above problems, and aims to provide a dispenser system that is an application system that can shorten the time required to adjust the amount of fluid to be applied to an object to be applied, and a filling system that can shorten the time required to adjust the amount of fluid to be filled into an object to be filled. [Means for solving the problem]

[0010] In order to achieve the above object, the present invention is configured as follows.

[0011] (1) A dispenser system according to the present invention comprises a dispenser device having a discharge port for discharging a fluid and a pump mechanism for moving the fluid relative to the discharge port, and capable of performing a discharge operation for operating the pump mechanism so that the fluid moves from the pump mechanism to the discharge port, and a suck-back operation for operating the pump mechanism so that the fluid moves from the discharge port to the pump mechanism; and a control device for controlling the operation of the dispenser device, and is capable of performing either or both of an application operation for applying a fluid to a workpiece by discharging the fluid onto the workpiece by the discharge operation and then performing the suck-back operation, and a filling operation for filling a workpiece with the fluid by discharging the fluid onto the workpiece by the discharge operation and then performing the suck-back operation, and is characterized in that the control device has an operation parameter setting unit for automatically setting a suction parameter that is correlated with the amount of fluid suctioned in the suck-back operation based on the suction conditions of the fluid.

[0012] According to the above-described dispenser system, suction parameters that correlate with the amount of fluid suctioned during suck-back operation are automatically set based on the fluid suction conditions, allowing a user to smoothly set the suction parameters without trial and error, for example, based on the dimensions of the cross section of the fluid applied to the workpiece. In this way, because the suction parameters related to the amount of fluid suctioned are automatically set by the operating parameter setting unit, complicated adjustment know-how is not required. As a result, the time required to adjust the amount of fluid suctioned during suck-back operation can be shortened, and the time required to adjust the amount of fluid applied to the workpiece can also be shortened.

[0013] Furthermore, according to the above-described dispenser system, suction parameters that correlate with the amount of fluid suctioned during suck-back operation are automatically set based on the fluid suction conditions, allowing the user to smoothly set the suction parameters without trial and error, for example, based on the mass of fluid filled into the workpiece. In this way, because the suction parameters related to the amount of fluid suctioned are automatically set by the operation parameter setting unit, complicated adjustment know-how is not required. As a result, the time required to adjust the amount of fluid suctioned during suck-back operation can be shortened, and the time required to adjust the amount of fluid filled into the workpiece can also be shortened.

[0014] (2) In the dispenser system according to the present invention, it is preferable that the operating parameter setting unit derives and sets discharge parameters that are correlated with the amount of fluid discharged by the pump mechanism unit based on the discharge conditions of the fluid, and the operating parameter setting unit sets the suction parameters based on the relationship with the discharge parameters set by the operating parameter setting unit. With this configuration, the suction parameters are automatically set based on the relationship with the discharge parameters, so that, for example, a user does not need to set the suction parameters through trial and error based on the state of the fluid applied to the workpiece. This eliminates the need for complicated work when setting the suction parameters, thereby shortening the time required to adjust the amount of fluid suctioned.

[0015] (3) In this case, the control device preferably has a parameter relationship generating unit that generates a relationship between the discharge parameter and the suction parameter based on actual values ​​related to the combination of the discharge parameter and the suction parameter. With this configuration, the relationship between the two is automatically generated by setting an appropriate suction parameter corresponding to the discharge parameter. Therefore, the user does not need to set an appropriate suction parameter corresponding to the discharge parameter in advance by trial and error.

[0016] (4) In the dispenser system having the parameter relationship generation unit, it is preferable that the parameter relationship generation unit generates the relationship between the discharge parameters and the suction parameters using at least one of linear interpolation using multiple points or a polynomial. With this configuration, it is possible to set appropriate suction parameters corresponding to the discharge parameters by using at least one of linear interpolation using multiple points or a polynomial. As a result, the relationship between the two is automatically generated, allowing the user to set appropriate suction parameters corresponding to the discharge parameters in advance without trial and error.

[0017] (5) In the dispenser system having the parameter relationship generation unit, it is preferable that the operating parameter setting unit sets the discharge parameters based on at least one of a target discharge amount of fluid to be discharged onto the workpiece during the discharge operation and a target application dimension of the application cross section. With this configuration, the discharge parameters for which corresponding suction parameters should be set are automatically set by the operating parameter setting unit based on at least one of the target discharge amount of fluid and the target application dimension of the application cross section, eliminating the need for the user to calculate the discharge parameters. Note that the target discharge amount is a concept that includes both mass and volume, and the target application dimension is a concept that includes both length and area.

[0018] (6) In the configuration in which the discharge parameters are set by the operating parameter setting unit, it is preferable that the operating parameter setting unit sets the discharge parameters based on at least one of the difference between the target discharge amount and the actual discharge amount of fluid discharged onto the workpiece during the discharge operation, and the difference between the target and actual coating dimensions of the coating cross section. With this configuration, the discharge parameters for which the corresponding suction parameters should be set are automatically set by the operating parameter setting unit based on at least one of the difference between the target and actual discharge amount of fluid, and the difference between the target and actual coating dimensions of the coating cross section, eliminating the need for the user to calculate the discharge parameters. The target discharge amount and the actual discharge amount are concepts that include both mass and volume, and the target and actual coating dimensions are concepts that include both length and area.

[0019] (7) In the dispenser system according to the present invention, the suction parameter is preferably an output and / or an operating time during the suck-back operation of the dispenser device. With this configuration, the dispenser device can be operated in the suck-back operation based on the output and / or the operating time corresponding to the suction parameter set by the operating parameter setting unit.

[0020] (8) In the dispenser system according to the present invention, it is preferable that the dispenser device is a single-axis eccentric screw dispenser. With this configuration, the operating parameters are approximately proportional to the discharge amount and suction amount, so that the calculated values ​​tend to match the actual values ​​and adjustments tend to converge. Furthermore, compared to dispenser devices such as air-type and screw-type dispensers, the discharge amount and suction amount are more proportional to the operating parameters, making adjustments easier. As a result, a dispenser system can be configured using a single-axis eccentric screw dispenser that can shorten the time required to adjust the amount of fluid applied to a workpiece. [Effects of the Invention]

[0021] According to the aspects of the present invention, it is possible to provide a dispenser system that constitutes an application system that can shorten the time required to adjust the amount of fluid to be applied to a workpiece, and a filling system that can shorten the time required to adjust the amount of fluid to be filled into a workpiece.

[0023] An application system, which is one embodiment of the dispenser system of the present invention, will now be described with reference to the accompanying drawings. These drawings are schematic diagrams and are not necessarily drawn to exact scale. In addition, like components in the drawings are designated by like reference numerals.

[0024] An application system 100 according to this embodiment will be described with reference to Figs. 1 to 12. As shown in Fig. 1(a), the application system 100 mainly includes a dispenser device 1, a dispenser control device 2, a robot 3, a robot control device 4, and an input / output device 5 (see Fig. 3). These devices are electrically connected by wired communication or wireless communication so as to enable one-way or two-way information communication. The dispenser control device 2 is mainly responsible for controlling the entire dispenser device 1. The robot control device 4 is mainly responsible for controlling the entire robot 3. The dispenser device 1 is attached to the robot 3.

[0025] The coating system 100 operates the dispenser device 1 as specified in accordance with the operating parameters derived and set based on the coating conditions defined in the dispenser control device 2, and also operates the robot 3 as specified based on the operating parameters derived and set based on the coating conditions defined in the robot control device 4. In this way, the coating system 100 performs a process of applying a fluid coating material to a workpiece (object to be coated) under predetermined coating conditions through a predetermined coating process.

[0026] 1(b), it is also possible to control both the dispenser device 1 and the robot 3 by consolidating the control functions of both the dispenser control device 2 and the robot control device 4 into one control device. On the other hand, it is also possible to configure the above control functions by dividing them into three or more control devices.

[0027] The dispenser device 1 is used to discharge and apply a fluid (coating material) to a workpiece (object to be coated). The dispenser device 1 is used to pump the coating material, and its main part is composed of a single-shaft eccentric screw pump 10. The dispenser device 1 operates in accordance with operation commands from a dispenser control device 2, driving a pump mechanism part 11 and discharging the coating material from a discharge port 12 provided at the tip, thereby performing point coating or line coating on the workpiece.

[0028] As shown in Figure 2, the uniaxial eccentric screw pump 10 is a rotary positive displacement pump. The uniaxial eccentric screw pump 10 has a male-screw rotor 13 that rotates eccentrically when powered, a stator 14 whose inner circumferential surface 14a is formed with a female thread, and a motor 15.

[0029] The rotor 13 is a metallic shaft body having an n-thread (n=1 in this embodiment) male screw shape. The stator 14 is a substantially cylindrical member having a through-hole 14b whose inner circumferential surface 14a is formed into an n+1-thread (n=1 in this embodiment) female screw shape. The uniaxial eccentric screw pump 10 is configured such that a pump mechanism 11, the main part of which is formed by inserting the rotor 13 into the through-hole 14b of the stator 14, is built into a pump casing 17. The pump mechanism 11 has the function of moving the coating material to the discharge port 12.

[0030] The motor 15 serves as a drive source for the uniaxial eccentric screw pump 10. The motor 15 is connected to the base end of the rotor 13 via a power transmission unit and an eccentric rotation unit (not shown). Therefore, by operating the motor 15, the uniaxial eccentric screw pump 10 can freely eccentrically rotate the rotor 13 inside the through-hole 14b.

[0031] The uniaxial eccentric screw pump 10 can move the fluid longitudinally through the fluid transport path 16 formed between the rotor 13 and the stator 14 by rotating the rotor 13 in the forward direction within the through-hole 14b of the stator 14. Therefore, by rotating the rotor 13, it is possible to suck the fluid into the fluid transport path 16 from one end of the stator 14, transport it toward the other end of the stator 14, and discharge it. In addition, the amount of fluid transported (discharged) can be controlled according to the amount of rotation of the rotor 13 (motor 15). Furthermore, the direction of movement of the fluid in the fluid transport path 16 can be switched by switching the rotation direction of the rotor 13 to the reverse direction.

[0032] The dispenser device 1 can perform a discharge operation in which the pump mechanism unit 11 is operated (forward rotation) so that the coating material moves from the pump mechanism unit 11 toward the discharge port 12, and a suck-back operation in which the pump mechanism unit 11 is operated (reverse rotation) so that the coating material moves from the discharge port 12 toward the pump mechanism unit 11. In other words, the dispenser device 1 can perform a discharge operation in which the coating material is discharged from the discharge port 12 by operating the pump mechanism unit 11 in the forward direction (forward rotation). Furthermore, the dispenser device 1 can perform a suck-back operation in which the coating material is sucked in by operating the pump mechanism unit 11 in the reverse direction (reverse rotation). Furthermore, the dispenser device 1 can perform a coating operation in which the coating material is applied to the workpiece by performing a suck-back operation after discharging the coating material onto the workpiece in the discharge operation.

[0033] The robot 3 is used to move the dispenser device 1 relative to the workpiece. An industrial robot is used as an example of the robot 3. The robot 3 can operate the robot arm based on a command signal from a robot operation control unit 41 of the robot control device 4. Therefore, the operation control of the robot operation control unit 41 can move the dispenser device 1 attached to the tip of the robot arm along a predetermined trajectory.

[0034] The input / output device 5 is a device for inputting and displaying coating conditions (coating information), inputting and displaying information for correcting (changing) discharge parameters and suction parameters, and outputting input information. Coating conditions include, for example, information regarding the coating pattern of the coating material, such as the target coating amount of the coating material to be applied to the workpiece, the target coating dimensions (coating diameter of the coating cross section, coating height), coating time, and coating speed, but are not limited to these conditions. The above-mentioned "amount" includes both volume and mass. The input / output device 5 also includes a touch panel. The touch panel has both a display function (display device 51) and an input function (input device 52) for coating information. The display device 51 is configured with a liquid crystal display device, an organic electroluminescence display device, or the like, and is configured to display various images (GUI), etc., as described below.

[0035] The input / output device 5 (touch panel) is configured to be able to display and / or input application conditions, operating parameters, and correction information for various images (GUI: Graphical User Interface) such as those shown in Figures 10 to 12 displayed on the display device 51.

[0036] As shown in FIG. 3, the dispenser control device 2 has an input receiving unit 21, an application condition setting unit 22, an operation parameter setting unit 23, a parameter relationship generation unit 24, an operation control unit 25, a memory unit 26, a correction information receiving unit 27, and a display control unit 28.

[0037] The input receiving unit 21 receives input of application conditions for the application material to the workpiece input by the user for various images displayed on the display device 51 of the input / output device 5, for example.

[0038] The coating condition setting unit 22 can set, as coating conditions, at least one of, for example, a target coating amount of the coating material to be applied to the workpiece, a target coating dimension of the coating cross section, and operating parameters. The coating dimension refers to the dimensions related to the coating diameter and coating height of the coating cross section when the coating material to be applied in dots to the workpiece is assumed to be a hemisphere of a spheroid. Note that the setting method described above is one example, and a calculation method for setting the coating diameter and / or coating height can be prepared separately as long as it is linked to the coating diameter and / or coating height. In addition, in the case of line coating, in which the coating material is applied to the workpiece in a line, a value related to the length of the line is relevant, and for example, the volume of the shape (semi-cylindrical shape) of the line of coating material when viewed in cross section may be calculated.

[0039] The operation parameter setting unit 23 derives and sets operation parameters that have a correlation with the amount of coating material applied to the workpiece based on the application conditions of the coating material. Note that "deriving and setting based on the application conditions of the coating material" includes cases where the operation parameter setting unit 23 sets the operation parameters fully automatically, and cases where the user sets the operation parameters by partially manually operating (inputting conditions) when setting the operation parameters.

[0040] The operating parameters include discharge parameters and suction parameters. The discharge parameters are parameters that correlate with the amount of the coating material discharged by the pump mechanism unit 11. The discharge parameters are derived and set based on the discharge conditions of the coating material. The discharge conditions are any numerical values ​​related to discharge input by the user to the dispenser control device 2, such as "discharge time" and "discharge rotation speed." The discharge parameters are, for example, the output and / or operation time of the dispenser device 1 during forward operation. The "output" refers to the rotation speed of the rotor 13 or the motor 15 in the case of a single-axis eccentric screw type, the moving speed of the plunger in the case of a plunger type, or the air pressure in the case of an air type. The suction parameters are parameters that correlate with the amount of the coating material suctioned by the pump mechanism unit 11. The suction parameters are derived and set based on the suction conditions of the coating material. The suction parameters are, for example, the output and / or operation time of the dispenser device 1 during suck-back operation. The suction condition is any numerical value related to suction input to the dispenser control device 2 by the user.

[0041] The operation parameter setting unit 23 can derive and set operation parameters by a method described below. For example, the operation parameter setting unit 23 can set operation parameters based on the coating conditions set in the coating condition setting unit 22, and then set the amount of coating material discharged by the discharge operation to increase in response to a decrease in the amount of coating material applied due to the suck-back operation.

[0042] The operation parameter setting unit 23 can derive and set the discharge parameters by a method described below. For example, the operation parameter setting unit 23 can derive and set the discharge parameters based on the discharge conditions of the coating material that are correlated with the discharge amount of the coating material by the pump mechanism unit 11, derive and set the discharge parameters based on the target discharge amount (or target application amount) of the coating material to be discharged (or applied) to the workpiece during discharge operation, and / or derive and set the discharge parameters based on the difference between the target discharge amount (or target application amount) of the coating material to be discharged (or applied) to the workpiece during discharge operation and the actual discharge amount (or actual application amount) of the coating material.

[0043] The operation parameter setting unit 23 can derive and set the suction parameters based on the relationship with the discharge parameters set by the operation parameter setting unit 23 .

[0044] Furthermore, coating system 100 can perform a calibration operation (initial setting) to optimize operating parameters according to coating conditions. In the calibration operation, operating parameter setting unit 23 provisionally sets the suction amount of coating material associated with suck-back operation as a provisional suction amount. For example, when provisionally setting the suction amount of coating material associated with suck-back operation as a provisional suction amount, operating parameter setting unit 23 is configured to calculate the provisional suction amount based on at least one of (1) a target coating amount and / or a target coating dimension, (2) discharge parameters such as forward rotation speed and / or time, (3) an arbitrary value input by the user, (4) a fixed value unrelated to other conditions or parameters, and (5) a suction parameter.

[0045] In other words, in the calibration operation, the operation parameter setting unit 23 initializes the suction amount (provisional suction amount) to a predetermined value, and also initializes the discharge parameters (rotation speed) based on the initially set provisional suction amount, target application dimensions, target application amount, application time, etc. Thereafter, the operation control unit 25 performs a test application in which a test application operation is carried out in accordance with the initially set discharge parameters.

[0046] As described above, in this embodiment, the operating parameter setting unit 23 initially calculates the initial forward rotation speed using a calculation formula that takes into account the decrease in coating amount due to reverse suction. For example, this is shown by the following formula: Forward rotation speed = ((discharge rate) + (provisional reverse suction rate)) / (theoretical discharge rate × forward rotation time). In other words, the numerator in the above formula sets the provisional coating amount as the sum of the discharge rate and the provisional reverse suction rate, with the aim of matching the provisional coating amount with the target coating amount. The target coating amount is calculated assuming a "spheroid hemisphere with the desired coating diameter and coating height." As described above, by taking the "provisional reverse suction rate" into account, it is possible to calculate a more appropriate (closer to the correct) forward rotation speed from the initial stage.

[0047] The parameter relationship generating unit 24 generates a relationship between a discharge parameter and a suction parameter based on actual values ​​relating to the combination of the discharge parameter and the suction parameter. The actual values ​​are based on past calculation results, simulation results, etc.

[0048] The operation control unit 25 controls the operation of the dispenser device 1 in accordance with the operation parameters set in the operation parameter setting unit 23.

[0049] The memory unit 26 stores (contains) in advance programs and data for controlling the entire dispenser device 1, and various images to be displayed on the display device 51. The memory unit 26 also stores the settings of application conditions (patterns) input by the user, and the history of set operating parameters, etc.

[0050] The correction information receiving unit 27 receives input of correction information related to the correction of operating parameters for adjusting the coating amount so as to obtain a desired coating amount. The correction information receiving unit 27 receives, as correction information, the actual coating dimensions and the actual coating amount of the coating cross section of the coating material applied to the workpiece, and the target coating dimensions and the target coating amount of the coating cross section of the coating material.

[0051] The correction information receiving unit 27 includes a discharge parameter correction information receiving unit 271 and a suction parameter correction information receiving unit 272. The discharge parameter correction information receiving unit 271 receives input of correction information related to the correction of discharge parameters for adjusting the discharge amount of the application material. The suction parameter correction information receiving unit 272 receives input of correction information related to the correction of suction parameters for adjusting the suction amount of the application material.

[0052] The operating parameter setting unit 23 corrects the operating parameters based on the correction information received by the correction information receiving unit 27. For example, the operating parameter setting unit 23 corrects the discharge parameters using the relationship between the actual application dimension and the target application dimension of the application material received by the correction information receiving unit 27. Note that the correction is not limited to the actual application dimension and the target application dimension, but may also be the actual application amount and the target application amount. Furthermore, the operating parameter setting unit 23 can correct the suction parameters using the relationship between the discharge parameter and the suction parameter based on the actual value related to the combination of the discharge parameter and the suction parameter.

[0053] The display control unit 28 controls the display device 51 of the input / output device 5 to display a coating condition display unit 281, an operation parameter display unit 282, and a correction information display unit 283. The coating condition display unit 281 displays the coating conditions accepted by the input accepting unit 21. The coating condition display unit 281 is, for example, an image relating to "width" and "height" in the coating shape designation image shown in FIG. 10(a).

[0054] The operation parameter display section 282 displays the operation parameters (discharge parameters and suction parameters) derived and set by the operation parameter setting section 23 based on the application conditions received by the input receiving section 21. The operation parameter display section 282 is, for example, an image relating to the "discharge rotation speed," "discharge time," "suction speed," and "suction time" in the application shape designation image shown in Fig. 10(a).

[0055] The correction information display unit 283 displays the correction information received by the correction information receiving unit 27. The correction information display unit 283 is, for example, an image relating to "suction speed," "suction time," "diameter," "height," and the like, as shown in Figs. 11 and 12.

[0056] Next, a procedure for adjusting the application amount of the application system according to this embodiment will be described with reference to FIGS.

[0057] As shown in FIG. 4, in step S1-1, the user inputs (sets) application dimensions, application time, and the like as application conditions for the material to be applied to the workpiece. At this time, for example, an application shape designation image (application condition display section 281 and operation parameter display section 282) as shown in FIG. 10(a) is displayed on the display device 51. The user operates the touch panel to input application dimensions ("width" and "height" shown in FIG. 10(a)) and application time (discharge time) and the like as application conditions for the material to be applied to the workpiece in response to the application shape designation image displayed on the display device 51. The information (application conditions) input by the user is accepted by the input accepting section 21 of the dispenser control device 2 and set as application conditions by the application condition setting section 22. In addition, when the "?" button in the image shown in FIG. 10(a) is pressed, an explanatory diagram relating to the application dimensions of the material to be applied is displayed as shown in FIG. 10(b). In this embodiment, the "suction speed" and "suction time" shown in Fig. 10(a) are displayed as fixed provisional values ​​in advance, but the user may be allowed to input a different value. When the user inputs a different value, the control may be such that the input value is not reflected in the calculation result of the "discharge rotation speed" in step S1-2 described later, or the control may be such that the input value is reflected in the calculation result.

[0058] Furthermore, if the provisional suction time is too long compared to the discharge time input by the user, the suction time may be automatically adjusted to be shorter. The aforementioned "fixed value" is a provisional value and can be set as appropriate. Alternatively, the "suction speed" and "suction time" may be automatically set based on application conditions such as the target application amount and / or target application dimension, or discharge parameters such as the forward rotation speed and / or time. In this embodiment, suction parameters such as the "suction speed" and "suction time" are displayed and / or input. Alternatively, or in addition to this, the "suction amount" and / or "provisional suction amount" may be displayed and / or input. In this case, the suction amount and provisional suction amount, like the suction speed and suction time, may be various values, such as a fixed value, a value input by the user, or a value automatically calculated based on the application conditions and discharge parameters.

[0059] Next, in step S1-2, the forward rotation speed of the dispenser device 1 is automatically calculated. At this time, the dispenser control device 2 performs the calculation after taking into account a provisional reverse suction amount (provisional suction amount) when calculating the forward rotation speed. Specifically, the operation parameter setting unit 23 provisionally sets the suction amount of the coating material associated with the suck-back operation as the provisional suction amount in the calibration operation (initial setting). Furthermore, the operation parameter setting unit 23 provisionally sets the operation parameter (forward rotation speed) based on the provisional application amount, which is the amount obtained by adding the provisional suction amount to the discharge amount of the coating material associated with the discharge operation. At this time, the operation parameter setting unit 23 performs the calculation based on the formula shown as forward rotation speed = ((discharge amount) + provisional reverse suction amount) / (theoretical discharge amount × forward rotation time). Note that if suction parameters such as suction speed and suction time are displayed and / or input on the application shape specification screen described above, the provisional suction amount can be calculated and used based on those values. On the other hand, when the suction volume or provisional suction volume is displayed and / or input, those values ​​can be used as the provisional suction volume as is, or another value calculated based on those values ​​can be used as the provisional suction volume.

[0060] Here, a method for calculating the rotational speed in the dispenser device 1 will be explained using an image diagram. As shown in FIG. 6, when the horizontal axis represents time t and the vertical axis represents the rotational speed V, region A represents the discharge amount during forward rotation, region B represents the suction amount during reverse rotation, and region C (shaded area) represents the amount that is not actually applied. In such a case, if the target application amount is 100, the conventional calculation method calculates A=100. As a result, since the decrease in B is not taken into consideration, the application amount may be, for example, 97, which is less than expected. On the other hand, the calculation method according to this embodiment calculates AB=100. In the initial calculation stage, the suction parameter is undetermined and the value of B (suction amount) is not confirmed, so a provisional value (provisional suction amount) is used in the calculation. This makes it possible to reduce errors compared to the conventional calculation method.

[0061] Next, in step S1-3 shown in FIG. 4, a test application (trial application) is performed in which an application operation is performed in accordance with the operation parameters provisionally set by the operation parameter setting unit 23.

[0062] Next, in step S2, the suction parameters are corrected to appropriate values. During the test application in steps S1-3, dripping or excessive suction often occurs, making it difficult to accurately measure the application amount and application dimensions. Therefore, the suction parameters are corrected (corrected) to appropriate values. The user sets suction parameters related to the suction time and suction speed based on the state of the application material when it runs out. For example, the user inputs "suction speed 1" and "suction time" as reverse suction conditions in the correction 1 image (correction information display unit 283) shown in FIG. 11(a) displayed on the display device 51. At this time, the information input by the user (correction information) is accepted by the suction parameter correction information accepting unit 272 of the correction information accepting unit 27 of the dispenser control device 2. Note that if a suck-back operation is not performed during the test application, no suction of the application material occurs. Therefore, the correction (correction) of the suction parameters in step S2 may include a case in which new conditions are set when a suck-back operation is not performed.

[0063] Next, in step S3, the operation parameter setting unit 23 derives and sets operation parameters based on the application conditions and suction conditions input in steps S1 and S2, and performs a test application with reverse suction. For example, the user touches the "operation 1" switch on the correction 2 image (correction information display unit 283) as shown in Figure 11(b) displayed on the display device 51 to eject the liquid several times.

[0064] Next, in step S4, the user actually measures (measures) the application dimensions of the coating material applied to the workpiece using a caliper, ruler, or the like. The user inputs the measured application dimensions ("diameter 1" and "height 1") in the correction 2 image as shown in FIG. 11(b) displayed on the display device 51. At this time, the information (correction information) input by the user is accepted by the correction information accepting unit 27 of the dispenser control device 2. Note that a measuring device or the like for measuring the application dimensions of the coating material may be provided at any position to automatically measure the application dimensions of the coating material. Furthermore, if a communication device for communicating the measurement results from the measuring device is provided, it is possible to automate both the measurement of the application dimensions and the parameter setting.

[0065] Next, as shown in FIG. 5, in step S5-1, based on the measurement results of step S4, the dispenser control device 2 predicts the range of forward rotation speeds that will likely result in the desired coating size, and issues an instruction to adjust the suction parameters at several forward rotation speeds within that range (displayed on the display device 51). At this time, for example, the user touches each of the switches for "Operation 2," "Operation 3," and "Operation 4" as shown in FIG. 12(a) to discharge the liquid, and a correction 3 image (correction information display unit 283) is displayed on the display device 51, which sets the parameters for "Suction Speed ​​2," "Suction Speed ​​3," and "Suction Speed ​​4" so that the liquid cutoff is appropriate. The display control unit 28 may also control the display device 51 to display an image such as "Please adjust the reverse suction for forward rotation speed x rotations." The above-mentioned adjustment (automatic setting) of reverse suction may also be performed based on a combination of only one forward rotation speed and reverse speed. In this case, a relationship is generated by artificial intelligence such as AI based on the parameters set in step S2, and steps S5-1 and S5-2 may be omitted.

[0066] Specifically, in step S4, when the user inputs the measurement results of the coating dimensions into a predetermined field on the correction 2 image shown in FIG. 11(b), the operation parameter setting unit 23 estimates (automatically specifies) the forward rotation speed range within which the desired coating amount can be obtained. The forward rotation speed range is determined by multiplying the ratio of the actual coating amount (calculated from the actual coating dimensions) obtained in step S4 to the target coating amount (calculated from the target coating dimensions) by a predetermined margin, and setting the result as the upper or lower limit of the range. A simpler variation is to specify the range by calculation or database utilization, etc., based only on the target coating amount, without using the actual coating amount in the calculation. Furthermore, in addition to the coating amount, the coating dimensions, i.e., diameter (width), height, or area (which may be calculated based on the diameter or height, or obtained by image processing, etc.), can also be used in the calculation.

[0067] For example, in the example shown in Figure 7, the horizontal axis represents the forward rotation speed [min -1 ], and the vertical axis is the reverse rotation speed [min -1], the forward rotation speed range is 10.0 to 20.9 [min -1 ] range. In addition, the forward rotation speed is 10.0 [min -1 ] has been adjusted and input in step S2, so in the corrected image 3 shown in Figure 12(a), the forward rotation speed is 13.6 [min -1 ], 17.3 [min -1 ], and 20.9 [min -1 The user is instructed to adjust and input the reverse rotation speed for each of the following. The reverse suction time is set constant and not changed. However, the reverse suction time may be set variable and the rotation speed may be set constant.

[0068] Next, in step S5-2, the user pre-adjusts the suction parameters corresponding to the specified forward rotation speed. For example, the user touches each of the "Operation 2," "Operation 3," and "Operation 4" switches in the correction 3 image displayed on the display device 51 as shown in FIG. 12(a) to discharge the liquid. Next, the user adjusts the parameters of "Suction Speed ​​2," "Suction Speed ​​3," and "Suction Speed ​​4" so that the liquid is properly cut off. After that, the user inputs the adjustment results from the input / output device 5 (touch panel), and the input results are accepted by the suction parameter correction information accepting unit 272 of the correction information accepting unit 27 of the dispenser control device 2. In this way, by setting appropriate reverse rotation speeds (suction parameters) corresponding to multiple forward rotation speeds (discharge parameters), a relationship between the two is generated. That is, the parameter relationship generating unit 24 generates a relationship between the discharge parameter and the suction parameter based on actual values ​​related to combinations of the forward rotation speeds (discharge parameters) and the reverse rotation speeds (suction parameters). For example, the parameter relationship generating unit 24 can generate the relationship by an approximation curve using multiple points. Specifically, in the example of Fig. 7, the relationship is generated by linear interpolation using two points, but linear interpolation using three or more points, or a polynomial, exponential approximation, logarithmic approximation, sine wave, etc. may also be used. By generating the relationship in this manner, when the forward rotation speed is changed, it becomes possible to automatically calculate appropriate suction parameters even if the changed forward rotation speed is not the forward rotation speed for which the suction parameters were set in step S2 or step S5-2. If it is confirmed in step S5-2 that appropriate liquid cut-off has occurred at the above three rotation speeds, proceed to the next step.

[0069] Next, steps S6 and S7 are repeatedly performed. In step S6, coating is performed based on the forward and reverse rotation speeds calculated by the operation parameter setting unit 23, and in step S7, the user measures the coating dimensions (diameter and height) of the coating material applied to the workpiece and inputs the measurement results. The processing contents of steps S6 and S7 will be described in detail below.

[0070] In step S6, the operating parameter setting unit 23 calculates the forward rotation speed based on the set dimensions set in step S1-1, and also calculates the reverse rotation speed based on the relationship between the forward rotation speed and the reverse rotation speed obtained in step S5. When calculating the forward rotation speed, for example, as shown in FIG. 8, a graph is referenced, in which the horizontal axis represents the forward rotation speed and the vertical axis represents the amount of coating material applied (the hemispherical volume of the spheroid calculated from the test application and the actually measured dimensions). In FIG. 8, Z(n-2) represents the rotation speed and coating amount applied in the (n-2)th application, and Z(n-1) represents the rotation speed and coating amount applied in the (n-1)th application. Z(0) can be the rotation speed and target coating amount for the next (nth) application as a corrected prediction.

[0071] The prediction after the above correction will be explained with reference to the image diagram in Figure 9. In Figure 9, as with Figure 8 described above, the horizontal axis represents the forward rotation speed, and the vertical axis represents the amount of coating material applied. In Figure 9(a), the first run is represented by "O" and the second run by "△". If the relationship between the amount applied and the rotation speed is linear, it is estimated that the amount of coating material applied at the calculated rotation speed will be the amount represented by "□". The amount that actually appears is represented by "◇". Next, in Figure 9(b), since the data from the past two runs is used for correction, "△" is replaced with "O" and "◇" is replaced with "△". By repeating the above calculation multiple times, the "O" and "△" become closer to each other, as shown in Figure 9(c).

[0072] As described above, it is only from the third test application onwards that corrections can be made (by connecting two points with a line) based on the relationship between the actual measured values ​​(actual values) from the past two times. Therefore, the first point is plotted by performing the calculations and measurements shown in steps S1 to S4 in the first test application. The second time, the rotation speed for the second test application is calculated by multiplying the difference (ratio) between the first measured application dimension and the desired application dimension by the first rotation speed. The second point is plotted by performing test application and actual measurement at this rotation speed. The third time, the rotation speed corresponding to the desired application dimension is derived by connecting the first and second points with a line. The method described above is repeated until the target application amount is achieved.

[0073] Next, in step S7, the user measures the application dimensions (diameter and height) of the application material applied to the workpiece and inputs the measurement results. For example, if multiple application dimensions are applied to the workpiece, the average values ​​of the application dimensions may be input. At this time, for example, the user inputs "diameter 2" and "height 2" as the application dimension measurement results in the correction 4 image (correction information display unit 283) as shown in FIG. 12(b) displayed on the display device 51. At this time, the information (correction information) input by the user is accepted by the discharge parameter correction information accepting unit 271 of the correction information accepting unit 27 of the dispenser control device 2, and the operation parameter setting unit 23 corrects the operation parameters based on the correction information. Note that steps S6 and S7 are repeated. At this time, as described above, in step S6, the operation parameter setting unit 23 calculates the forward rotation speed based on the relationship between the actual measurement dimensions measured in steps S4 and S7 and the set dimensions set in step S1-1, and also calculates the reverse rotation speed based on the relationship between the forward rotation speed and the reverse rotation speed obtained in step S5.

[0074] According to the embodiment described above, the following effects (1) to (8) can be obtained.

[0075] (1) In the coating system 100 according to the above embodiment, the operating parameter setting unit 23 automatically sets suction parameters that correlate with the amount of fluid suctioned during suck-back operation based on the fluid suction conditions. According to the above embodiment, the suction parameters that correlate with the amount of fluid suctioned during suck-back operation are automatically set based on the fluid suction conditions. This allows the user to smoothly set the suction parameters based on the state of the fluid applied to the workpiece without trial and error. In this way, because the suction parameters related to the amount of fluid suctioned are automatically set by the operating parameter setting unit 23, complicated adjustment know-how is not required. As a result, the time required to adjust the amount of fluid suctioned during suck-back operation can be shortened, and therefore the time required to adjust the amount of fluid applied to the workpiece can also be shortened.

[0076] (2) In the coating system 100 according to the above embodiment, the operating parameter setting unit 23 sets the suction parameters based on the relationship with the discharge parameters set by the operating parameter setting unit 23. As a result, the suction parameters are automatically set based on the relationship with the discharge parameters, so that, for example, a user does not need to set the suction parameters by trial and error based on the state of the fluid applied to the workpiece. This eliminates the need for complicated work when setting the suction parameters, and therefore reduces the time required to adjust the amount of fluid suctioned.

[0077] (3) In the coating system 100 according to the above embodiment, the parameter relationship generating unit 24 generates the relationship between the discharge parameter and the suction parameter based on the actual values ​​relating to the combination of the discharge parameter and the suction parameter. As a result, the relationship between the two is automatically generated by setting an appropriate suction parameter corresponding to the discharge parameter. Therefore, the user does not need to set an appropriate suction parameter corresponding to the discharge parameter in advance by trial and error.

[0078] (4) In the coating system 100 according to the above embodiment, the parameter relationship generation unit 24 generates the relationship between the discharge parameters and the suction parameters using at least one of linear interpolation using multiple points and a polynomial. This makes it possible to set appropriate suction parameters corresponding to the discharge parameters by using at least one of linear interpolation using multiple points and a polynomial. This automatically generates the relationship between the two, allowing the user to set appropriate suction parameters corresponding to the discharge parameters in advance without trial and error.

[0079] (5) In the coating system 100 according to the above embodiment, the operating parameter setting unit 23 sets the discharge parameters based on at least one of the target discharge amount of the fluid to be discharged onto the workpiece during the discharge operation and the target coating dimension of the coating cross section. As a result, the discharge parameters for which the corresponding suction parameters should be set are automatically set by the operating parameter setting unit 23 based on at least one of the target discharge amount of the fluid and the target coating dimension of the coating cross section, eliminating the need for the user to calculate the discharge parameters by calculation or the like.

[0080] (6) In the coating system 100 according to the above embodiment, the operating parameter setting unit 23 sets the discharge parameters based on at least one of the difference between the target discharge amount of the fluid discharged onto the workpiece during the discharge operation and the actual measured discharge amount of the fluid, and the difference between the target coating dimension and the actual measured coating dimension of the coating cross section. As a result, the discharge parameters for which the corresponding suction parameters should be set are automatically set by the operating parameter setting unit 23 based on at least one of the difference between the target discharge amount of the fluid and the actual measured discharge amount, and the difference between the target coating dimension and the actual measured coating dimension of the coating cross section, eliminating the need for the user to calculate the discharge parameters by calculation, etc.

[0081] (7) In the coating system 100 according to the above embodiment, the suction parameters are the output and / or operation time during the suck-back operation in the dispenser device 1. This allows the dispenser device 1 to perform the suck-back operation based on the output and / or operation time corresponding to the suction parameters set by the operation parameter setting unit 23.

[0082] (8) In the coating system 100 according to the above embodiment, the dispenser device 1 is configured as a single-axis eccentric screw dispenser. As a result, the operating parameters are approximately proportional to the discharge amount and suction amount, so that the calculated values ​​tend to match the actual values ​​and adjustments tend to converge. Furthermore, compared to air-type or screw-type dispensers, the discharge amount and suction amount are more proportional to the operating parameters, making adjustments easier. As a result, a coating system 100 can be configured using the single-axis eccentric screw dispenser device 1, which can shorten the time required to adjust the amount of fluid to be applied to the workpiece.

[0083] (Other embodiments) Next, referring to FIG. 13, a filling system 110 according to another embodiment of the dispenser system of the present invention will be described.

[0084] As shown in FIG. 13, the filling system 110 mainly includes a dispenser device 1, a dispenser control device 2, a robot 3, and a robot control device 4. These devices are electrically connected by wired communication or wireless communication so as to enable one-way or two-way information communication. The dispenser control device 2 mainly controls the entire dispenser device 1. The robot control device 4 mainly controls the entire robot 3. The dispenser device 1 is attached to the robot 3.

[0085] In this embodiment, the filling system 110 differs from the above-described application system 100 only in that the filling system 110 fills a workpiece 130 (object to be filled) such as a container with a filler 120 discharged from a dispenser device 1 of the filling system 110. Therefore, the configuration provided in the application system 100 can be replaced with the filling system 110.

[0086] According to the embodiment described above, the following effects (9) to (16) can be obtained.

[0087] (9) In the filling system 110 according to the above embodiment, the operating parameter setting unit 23 automatically sets the suction parameters, which are correlated with the suction amount of the filler material 120, based on the suction conditions of the filler material 120. According to the above embodiment, the suction parameters, which are correlated with the suction amount of the filler material 120 during the suck-back operation, are automatically set based on the suction conditions of the filler material 120. This allows the user to smoothly set the suction parameters without trial and error, for example, based on the state of the filler material 120 filled into the workpiece 130. In this way, because the suction parameters related to the suction amount of the filler material 120 are automatically set by the operating parameter setting unit 23, complicated adjustment know-how is not required. As a result, the time required to adjust the suction amount of the filler material 120 during the suck-back operation can be shortened, and therefore the time required to adjust the filling amount of the filler material 120 filled into the workpiece 130 can also be shortened.

[0088] (10) In the filling system 110 according to the above embodiment, the operating parameter setting unit 23 sets the suction parameters based on the relationship with the discharge parameters set by the operating parameter setting unit 23. As a result, the suction parameters are automatically set based on the relationship with the discharge parameters, so that the user does not need to set the suction parameters by trial and error based on the state of the filler 120 filled in the workpiece 130, for example. This eliminates the need for complicated work when setting the suction parameters, and therefore reduces the time required to adjust the suction amount of the filler 120.

[0089] (11) In the filling system 110 according to the above embodiment, the parameter relationship generating unit 24 generates a relationship between the discharge parameter and the suction parameter based on the actual values ​​relating to the combination of the discharge parameter and the suction parameter. As a result, the relationship between the two is automatically generated by setting an appropriate suction parameter corresponding to the discharge parameter. Therefore, the user does not need to set an appropriate suction parameter corresponding to the discharge parameter in advance by trial and error.

[0090] (12) In the filling system 110 according to the above embodiment, the parameter relationship generating unit 24 generates the relationship between the discharge parameters and the suction parameters using at least one of linear interpolation using multiple points and a polynomial. This allows the use of at least one of linear interpolation using multiple points and a polynomial to set appropriate suction parameters corresponding to the discharge parameters. This automatically generates the relationship between the two, allowing the user to set appropriate suction parameters corresponding to the discharge parameters in advance without trial and error.

[0091] (13) In the filling system 110 according to the above embodiment, the operation parameter setting unit 23 sets the discharge parameters based on the target discharge amount of the filler 120 to be discharged onto the workpiece 130 during the discharge operation. As a result, the discharge parameters for which the corresponding suction parameters should be set are automatically set by the operation parameter setting unit 23 based on the target discharge amount of the filler 120, eliminating the need for the user to calculate the discharge parameters by calculation or the like.

[0092] (14) In the filling system 110 according to the above embodiment, the operation parameter setting unit 23 sets the discharge parameters based on the difference between the target discharge amount of the filler 120 discharged onto the workpiece 130 during the discharge operation and the actual discharge amount of the filler 120. As a result, the discharge parameters for which the corresponding suction parameters should be set are automatically set by the operation parameter setting unit 23 based on the difference between the target discharge amount of the filler 120 and the actual discharge amount, eliminating the need for the user to calculate the discharge parameters by calculation or the like.

[0093] (15) In the filling system 110 according to the above embodiment, the suction parameters are the output and / or operation time during the suck-back operation in the dispenser device 1. This allows the dispenser device 1 to perform the suck-back operation based on the output and / or operation time corresponding to the suction parameters set by the operation parameter setting unit 23.

[0094] (16) In the filling system 110 according to the above embodiment, the dispenser device 1 is configured as a single-axis eccentric screw dispenser. As a result, the operating parameters are approximately proportional to the discharge amount and suction amount, so that the calculated values ​​tend to match the actual values ​​and adjustments tend to converge. Furthermore, compared to air-type or screw-type dispensers, the discharge amount and suction amount are more proportional to the operating parameters, making adjustments easier. As a result, a filling system 110 can be configured using the single-axis eccentric screw dispenser device 1, which can shorten the time required to adjust the amount of filler 120 to be filled into the workpiece 130.

[0095] (Other variations) The above embodiment can be modified as follows.

[0096] In the above embodiment, an example of applying a uniaxial eccentric screw type is shown as an example of a dispenser device, but the present invention is not limited to this. In the present invention, any type of dispenser device that can perform suck-back operation, such as a plunger type (piston type), a valve type, a screw type, or an air type, can be used.

[0097] In the above embodiment, the application diameter, application height, and application time of the application material are mainly shown as examples of application conditions, but the present invention is not limited to this.

[0098] In the above embodiment, the case of point application in which the coating material is applied to the workpiece in points has been described, but the present invention is not limited to this. In the present invention, in the case of line application in which the coating material is applied to the workpiece in a line, a value related to the application length (length of the line) can be the application condition. For example, it may be necessary to calculate the volume of the shape (semi-cylindrical) of the line of coating material when viewed in cross section. Furthermore, in the case of line application, the application speed (relative movement speed of the dispenser device with respect to the workpiece) can be used as the application condition instead of the application time.

[0099] In the above embodiment, an example of managing the application conditions based on the application size has been shown, but it is also possible to manage the application conditions based on the application amount (volume or mass).

[0100] In the above embodiment, when the suction parameters are set by the operation parameter setting unit, an example is shown in which the user determines the suction parameters through application tests and inputs them to the dispenser control device, but the present invention is not limited to this. In the present invention, by automating the measurement of the dimensions of the applied coating material, etc., it becomes possible for the control device to automatically set the suction parameters without the user having to input them to the control device.

[0101] In the above embodiment, as an example of the operation parameters (discharge parameters and suction parameters), the discharge parameters are the output and / or operation time during forward rotation operation of the dispenser device, and the suction parameters are the output and / or operation time during suck-back operation of the dispenser device, but the present invention is not limited to this. In the present invention, it is sufficient that the operation parameters have a correlation with the amount of coating material applied to the workpiece, and for example, the movement speed or movement distance of the robot can also be included in the operation parameters.

[0102] In the above embodiment, an input / output device (touch panel) in which a display device and an input device are integrated has been shown, but the present invention is not limited to this. In the present invention, the display device (e.g., a display or monitor) and the input device (e.g., a keyboard, a numeric keypad, a mouse, etc.) can also be configured as separate devices. Also, an input / output device such as a touch panel may be provided on the housing of the control device, or the touch panel provided on the housing of the control device may be eliminated and data may be input and displayed using a completely separate (separate) PC or tablet.

[0103] In the above embodiment, the application shape designation image (FIG. 10) is configured so that the user can input application conditions, etc., but in addition to this, when the user inputs application conditions, etc., a figure reflecting the application conditions, etc. may be displayed on the application shape designation image, etc. of the display device. This allows the user to visually confirm the application shape of the applied material.

[0104] In the above embodiment, the application shape designation image (FIG. 10) is configured so that the user can input application conditions, etc., but in addition to this, it is also possible to input shapes and change sizes using drawing methods such as autoshape, that is, by dragging with a mouse or by pinching in (reducing) and pinching out (enlarging) on ​​a touch panel, by moving the thumb and index finger closer together and apart, and these can be automatically reflected in the dimension values.

[0105] In the above embodiment, the application shape designation image (Figure 10) is configured so that the user can input application conditions, etc., but in addition to this, an input section or selectable selection button may be provided that allows the user to input a "magnification" for enlarging or reducing the application dimension, so that the application dimension can be adjusted by the user inputting (selecting) the "magnification."

[0106] In the above embodiment, the application shape designation image (FIG. 10) is configured so that the user can input application conditions, etc., but in addition to this, it is also possible to display in advance "numerical values" for enlarging or reducing the application size, and have the user adjust the application size by selecting the "numerical value" button (or by touching the panel, in the case of a touch panel).

[0107] The above-described modifications of the application system can also be applied as similar modifications to the above-described filling system.

[0108] The above-described embodiments are merely examples of applications of the present invention, and it goes without saying that any other embodiments within the scope of the claims are also included in the technical scope of the invention. [Explanation of symbols]
