Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch panel display device, which is mounted as an operation panel device in a control device or other devices and which is touched (touched) by an operator or an operating finger of an operating machine. Of the touch panel display device for operating the above equipment from the outside.

[0002]

2. Description of the Related Art Conventionally, as a touch panel display device of this type, as shown in FIG. 10, for example, a main control unit 1 is connected to an image display unit 5 such as a liquid crystal display or a plasma display via a display control unit 3. , A touch panel portion 7 having a large number of switch elements (not shown in FIG. 10) that are turned on by a touch from the outside in a matrix and having good transparency is superimposed on the image display surface, and the touch panel portion 7 is connected to the switch detection portion 9. In addition, a configuration is known in which the switch detection unit 9 is connected to the main control unit 1.

That is, the display control unit 3 controls the image display on the image display unit 5 based on the operation image data output from the main control unit 1, and the switch signals from the individual switch elements of the touch panel unit 7 are detected by the switch detection unit. 9 detects the switch-on position from the outside, and the main control unit 1 specifies the image display area corresponding to the switch-on position, so that any operation can be performed via the touch panel unit 7. The main control unit 1 determines whether the external input has been made.

The touch panel display device having such a structure is separated or integrated with a control device 11 which mainly forms a sequence controller, a programmable controller, and the like, and the main control section 1 uses the transmission line through various transmission lines. It is connected to the control device 11. Then, the image data displayed on the image display unit 5 is transmitted from the control device 11 side to the main control unit 1, and the control device 11
While the measured value and the operating condition of the control target A connected to can be monitored, the set value and the operation content set / operated on the touch panel unit 7 are transmitted to the control device 11 via the main control unit 1, and the control device 11 The control target A is controlled.

Therefore, the operator, for example, as shown in FIG. 11, the image display 15 of the image display unit 5 arranged on the operation surface side of the main body case 13 of the control device 11, that is, the ten-key display 15a, and the arrow keys for moving the cursor. While touching the display 15b, the table display 15c, the function key display 15d, the shift key display 15e, etc., by touching those display areas of the touch panel unit (transparent and invisible in FIG. 11) 7 with a finger or a pen, The number of inputs and operation inputs corresponding to the touch area become possible, and the information is transmitted to the control device 11.

As the function key display 15d, for example, eight kinds of key images F1 to F8 are displayed, and when the shift key display 15e and any function key display 15d (F1 to F8) are pressed, the function key display is displayed. In many cases, the functions of 15d (F1 to F8) are changed and 16 kinds of functions can be selected. By the way, in the touch panel section 7 described above, for example, as shown in FIG. 12, the flexible sheets 21 and 23 in which a large number of elongated electrodes 17 and 19 are formed on one side in the shape of a comb are sandwiched with the spacer 25 therebetween. The electrodes 17 and 19 are stacked in a state of being orthogonal to each other, and are formed so as to be entirely transparent.

By touching a finger or the like from one side of the touch panel portion 7, the counter electrodes 17 and 19 are brought into contact with each other to be turned on.
Each switch element 27 is formed by 19. A plurality of adjacent switch elements 27 among these switch elements 27 form individual switch areas corresponding to individual image display areas.

That is, in FIG. 11, each numeric key display area of the ten-key display 15a and arrow key display 15b.
Individual arrow display area, function key display 15d
The function key display areas F1 to F8, the shift key area of the shift key display 15e, and the like are image display areas, and individual switch areas are formed on the touch panel portion 7 so as to overlap with them.

When such a touch panel display device is used in, for example, an extrusion molding line, while the operator actually sees the rotational speed of the motor and other movable parts of the mechanical system, he or she can move them quickly or slowly. Although it is necessary to have a speed adjustment operation function of moving the touch panel, the conventional touch panel display device is inferior in this kind of operability. Therefore,
As shown in FIG. 13, a configuration has been proposed in which the external operation device 29 is installed near the control device 11.

This configuration has a so-called jog shuttle or the like that can accelerate or decelerate a variable amount according to a rotation angle like a dial operation knob 31 outside the control device 11 in which the touch panel section 7 is integrally mounted as in FIG. External controller 29
Is to be placed. With the configuration of FIG. 13, for example, when the extrusion molding line is set up, the number of rotations of the motor is increased while observing the state of the line, and at the time of manufacturing, the dial operation knob 31 is rotated while observing the quality of the actual molded product. It is designed to be operated, and an image related to this operation is displayed on the image display unit 5.

Further, as shown in FIG. 14, the control device 11
The dial operation knob 31 and the like described above are arranged on the front surface of the
In some cases, the same operation as in the configuration of 3 may be performed. Note that FIG.
In addition, in the configuration of FIG. 14, a plurality of external operation devices 29 or dial operation knobs 31 are arranged as necessary.

[0012]

However, as shown in FIG. 13 described above, when an external operating device 29 having a different structure is externally connected to the control device 11 including the touch panel display device, a plurality of external operating devices 29 may be connected in some cases. Since the control system may be connected, the number of operating parts is increased in the entire control system, the number of operating parts operated by the operator is widened, and the configuration is likely to be complicated. Also, as shown in FIG. 14, the dial operation knob 3
Since the control device 11 having No. 1 is apt to have a complicated mechanical structure and it is necessary to reduce the size of the image display unit 5 by the space for disposing the dial operation knob 31 or to increase the size of the control device 11, The visibility is improved and the equipment is simple.
This conflicts with the general demand for miniaturized control equipment.

The present invention has been made in order to solve such a drawback, and a small-sized touch panel display device capable of performing a variable amount of acceleration / deceleration operation by touch operation and requiring no mechanical parts such as dial operation knobs. For the purpose of provision.

[0014]

In order to solve such a problem, a touch panel display device of the present invention displays an image display section having an optical image display surface and an image display of the image display section based on image data. A display control unit for controlling, a touch panel unit having a plurality of switch elements, which are turned on or off by a touch from the outside, in a matrix form and the image display surface of the image display unit is transparently overlapped on the touch panel unit, and the touch panel unit. Of the switch elements that are turned on or off, and the change speed of the image display of the image display section is determined according to the number of switch elements in the specific area detected by the switch detector. And a speed determination unit that outputs a speed signal, and outputs the image data and controls the changing speed of the image data according to the speed signal. That has a main control unit.

The main control section in the present invention is
Control the changing speed of the operation amount according to the speed signal,
It is preferable that the changing speed of the set value during image display is controlled and the changing set value is output to the outside, and further, the switching speed of the entire image display is controlled. Further, the main controller in the present invention can be formed so as to externally output the sound changed according to the speed signal.

[0016]

According to the present invention having such means, when the display control section displays an image on the image display section based on the image data from the main control section, when a specific area of the touch panel section is touched, the touched area is touched. The switch detection unit detects the switch element, the speed determination unit determines the change speed according to the number of the detected switch elements and outputs a speed signal to the main control unit, and the main control unit responds to the speed signal by the above The change speed of the image data is changed and output.

Then, the operating speed is controlled according to the speed signal from the speed determining unit, the changing speed of the set value during image display is controlled and the changed set value is output, and further, the image is displayed. In the configuration in which the main control unit is formed so as to control the switching speed of the entire display, the operation amount, the set value, and the changing speed of the image switching can be changed only by increasing or decreasing the touch area of the touch panel unit with respect to the specific area.
Further, if the main control unit is formed so as to output the sound changed according to the speed signal, the changing speed can be detected without checking the image display unit.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. Note that, except for the main part of the present invention, the same reference numerals are given to the parts common to the conventional configuration. FIG. 1 is a block diagram showing an embodiment of a touch panel display device according to the present invention. In FIG. 1, the main control unit 33 outputs a plurality of other image data for operation (see FIG. 3 and FIG. 9 described later) to the display control unit 35, and also operates according to the type of switch operated externally. And a function of outputting an operation amount to an external movable part, for example, an operation device (not shown) of a motor of an extrusion molding line via a control device 11 described later. There is.

The display control section 35 is connected to an image display section 37 which is a known image display means having an optical image display surface such as a liquid crystal display, a plasma display or a CRT display, and the main control section 33. The image layout of the image display unit 37 is controlled based on the image data for operation from. On the image display surface of the image display unit 37, the touch panel unit 39 is directly or overlaid at some intervals.

The touch panel section 39 has a structure as shown in FIG. 12 described above, and a plurality of switch elements 27 which are turned on by an external touch are arranged in a matrix form so that the display surface of the image display section 37 can be seen. It is formed so as to be transparent. For example, as shown in FIG. 2, nine switch elements 27 arranged vertically and horizontally (reference numerals in FIG.
), A switch area SW is formed, and the switch area SW is correspondingly arranged so as to overlap with the image display area 45 of the symbol “A” on the image display surface (omitted in FIG. 2) of the image display unit 37.

The switch elements 27 of the touch panel section 39 can be formed so that the switches are turned off by an external touch. Touch panel section 39
Is connected to the switch detector 41. Actually, each electrode forming each switch element 27 (see FIG. 12) 1
Reference numerals 7 and 19 extend from the end of the touch panel section 39 and are connected to the switch detection section 41.

The switch detector 41 includes electrodes 17 and 19
The position of which switch element 27 is turned on is detected based on the switch signal depending on the conduction state of the switch, and the switch region SW to which the turned on switch element 27 belongs is detected. For example, as shown in FIG. 2, when the lower right portion of the image display area 45 is touched with the fingertip 47, the switch element of the switch area SW is turned on, and the switch detection unit 41 detects the switch element to detect the switch. The detection signal of the area SW is output.

Further, the switch detection section 41 has a certain period (for example, 100 seconds) in order to prevent malfunction due to noise.
ms) It also has a normal malfunction prevention function such that the switch element detects an ON operation when continuously touched. It goes without saying that even if the image display area 45 is touched with the fingertip 47, the corresponding area on the touch panel unit 39 is actually touched.

The speed determination section 43 outputs the detection signal from the switch detection section 41 to the main control section 33, and on the other hand, turns the switch detection section 41 on or off to detect a specific switch area (specific area) detected by the switch detection section 41. Switch element 27
It has a function to be described later as well as to determine the changing speed of the image according to the number of. Here, before describing the function of the speed determination unit 43, the image display displayed on the image display unit 37 based on the image data from the main control unit 33 will be described with reference to FIG. 3 for convenience.

FIG. 3 shows an image display 15 including a schematic configuration diagram of an extrusion molding line and the like together with the control device 11. 3, in the lower part of the screen, in addition to the arrow key display 15b, the function key display 15d and the shift key display 15e similar to those in FIG. 11, a set value increasing key (+ key) 49 for operating the movable part of the mechanical system is provided. And the set value lowering key (-key) 51 are those keys 15b, 15c,
It is arranged in a larger area than 15d and 15e.

On the other hand, a schematic view of the inflation process of the extrusion molding line is shown in the upper part of the screen. The left part of the drawing is the winding machine 53a and the take-up machine 53b of the extrusion molding line.
The right part is a schematic view of the cylinder part 53c and the extruder 53d. The switch areas of the set value up key 49 and the set value down key 51 correspond to the above-mentioned specific switch area.

The cylinder portion 53c of the extruder 53d has a column for selectively displaying set values, measured values and the like for temperature control of the heaters 1 to 4, and the hopper portion 53e displays the hopper temperature. Further, the screw motor portion has a display of the number of rotations indicating the rotation of the motor, and the measurement input from the sensor for measuring the number of rotations of the motor is displayed.

In FIG. 3, the position of the number of revolutions is directly touched with a finger or the cursor (not shown, the same applies hereinafter) is moved by the arrow key display 15b to specify the value, and then the set value increasing key 49 or the setting value is set. By touching the value down key 51 with the fingertip 47, the screw rotation is increased or decreased. In this case, the switch detection unit 41 detects the number of rotations and the touch operation on the arrow key display 15b, and the main control unit 33 determines that the instruction is to change the number of rotations and raises or lowers the number of rotations. Create and output image data.

4 to 8 show the above-mentioned set value increasing key 4
9 and the set value decrease key 51, the set value increase key 49 is taken as an example to explain the function thereof, and the set value decrease key 51 is also the same. 4 to 8, the left side is the image display area 45 of the set value increasing key 49, and the right side is the image display area 45.
A specific switch area SW1 is formed by arranging nine rectangular areas composed of individual switch elements 27 vertically and horizontally. The array shape of the set value up key 49 and the set value down key 51 is not limited to this, and may be any shape such as a circle or an ellipse.

4 to 8, FIG. 4 shows a state in which the set value increasing key 49 is not pushed with the fingertips 47, and FIG. 5 shows an example of pushing with the three fingertips 47. The black part in the specific switch region SW1 is the part where the switch element 27 is on (the same applies hereinafter).
In FIG. 5, 42 of the 81 switch elements 27 are turned on. In FIG. 6, the set value increase key 49 is pressed with two fingertips 47.
This is an example of pressing with, and 29 out of 81 switch elements 27
The individual is turned on, and in FIG. 7, press with one fingertip 47
This is an example in which five switch elements 27 are turned on, and FIG. 8 is an example in which five switch elements 27 are turned on by pushing a narrow portion with one fingertip 47.

The speed determining unit 43 described above determines speed changes of four ranks corresponding to the number of switch elements 27 (ON areas) which are turned on as shown in FIGS. 4 to 8, and speeds corresponding to the ranks. It has a function of outputting a signal to the main control unit 33. The speed determining unit 43, for example, as shown in FIG. 5, the speed rank 1 when 40 or more of the 81 switch elements 27 are turned on, and the speed rank 2 when 20 or more and less than 40 as shown in FIG. As described above, 10 or more and less than 20 are speed rank 3, and less than 10 are speed rank 4 as shown in FIG. 8, and the correspondence relationship between the number of operated on-switch elements 27 and the speed rank is set in advance. It has a function of outputting a speed signal that is stored and corresponds to the number of switch elements 27 that are turned on.

When a speed signal of speed rank 1 is input, the main control unit 33 makes the above-mentioned rotational speed display portion at the highest speed in the image data to be displayed on the image display unit 37 via the display control unit 35. It has a function of variably outputting, decreasing the changing speed in the order of speed rank 2 and speed rank 3, and changing and outputting at the lowest speed in speed rank 4.

Next, the operation of the above-described touch panel display device of the present invention will be briefly described. For example, based on the image data from the main control unit 33, the display control unit 35 causes the image display unit 37 to display a schematic configuration diagram such as an extrusion molding line as shown in FIG. When the location is directly touched with a finger or designated by touching the arrow key display 15b and then the set value increasing key 49 is touched with the fingertip 47, the switch detection unit 41 detects each touched switch element 27.

The speed determining unit 43 determines the changing speed according to the number of the ON switch elements 27 and feeds back the speed signal to the main control unit 33. The main control unit 33 determines the speed with respect to the rotation speed of the motor. Since the image data including the rotation speed that changes at the speed corresponding to the signal is sequentially created and output, the rotation speed of the motor in the image display unit 37 increases and changes at a predetermined timing. The speed of change is speed rank 1 as shown in FIG.
If it is the highest speed, if it is speed rank 2 as shown in FIG. 6, it is a little faster, if it is speed rank 3 it is at medium speed, and if it is speed rank 4 as shown in FIG. If it is slow, it will change as I said.

Therefore, in order to speed up the rotation speed of the motor quickly, it is sufficient to touch a wide area of the set value increasing key 49 with a plurality of fingertips 47 from the beginning as shown in FIG.
When it is desired to increase the number of rotations little by little, the touch area of the fingertip 47 may be increased in the reverse order as shown in FIGS. Note that when the set value down key 51 is touched with the fingertip 47, the basic operation is the same as that of the set value up key 49, only the rotational speed of the motor in the image display unit 37 is changed downward.

However, regarding the speed operation of the motor,
When the rotation speed has an upper limit and a lower limit and exceeds the limit value, the limit value is fixed, and the changing speed has a change rate limit value (limit value). It has the function of changing the decelerated speed rank and decelerating.
For example, when the speed determination unit 43 rapidly changes the speed rank from 4 to 1, it may cause a failure of the load, the motor, etc. Therefore, when the speed of change exceeds the limit value, the main control unit 3
In 3, the speed rank may be changed to 3 and the speed may be reduced.

As described above, in the touch panel display device of the present invention, the main control unit 33 is connected to the image display unit 37 via the display control unit 35, and the image data from the main control unit 33 is displayed on the image display unit 37. The touch panel section 39 that is displayed and overlapped with the image display section 37 is connected to the switch detection section 41, and the touched switch element 27 among the switch elements 27 forming the touch panel section 39 is detected by the switch detection section 41. The part 41 is connected to the main control part 33 via the speed fixing part 43, and the speed of changing the speed according to the number of switch elements touching the set value increase key 49 or the set value decrease key 51 of the touch panel part 39 with the fingertip 47 is set. The unit 43 determines and outputs the speed signal to the main control unit 33, and the main control unit 33 changes the increase or decrease speed of the rotation speed of the motor according to the speed signal. It is so arranged to output the image data, by simply increasing or decreasing the touch area of the set value increase key 49 and set values down key 51 can be changed to increase or decrease the speed of rotation of the motor.

Moreover, the rotation speed of the motor can be changed to high speed, medium speed, low speed, or the like by a simple fingertip operation such as simply adjusting the touch area of the fingertip 47.
After confirming the position of, the rotational speed of the motor can be accelerated and decelerated without continuing to look at the touch panel unit 39, and the operability is improved. Further, since the acceleration / deceleration operation can be performed only by the touch operation on the touch panel portion 39, and the dial operation knob 31 is not required as in the above-described FIG. 13 and FIG. 14, the operation area operated by the operator is not widened,
The mechanical structure does not become complicated.

By the way, in the above-described embodiment, the speed rank is set to 1 to 4 depending on the number of the switch elements 27 touched.
However, the present invention is not limited to this. For example, in the image display area 45 of FIG. 4, 45%
When the above switch elements 27 are operated, the speed rank 1 is set, and when 30% or more and less than 45% of the switch elements 27 are operated, the speed rank 2 is set, and 15% or more and less than 30% of the switch elements 27 are operated. Speed rank 3
As described above, when less than 15% of the switch elements 27 are operated, the speed rank is set to 4 and the image display area 4 is set.
It is also possible to previously set and store a speed rank based on the ratio of the ON switch elements 27 to the number of all the switch elements 27 in 7, and to form the speed determining unit 43 so that the speed signal can be output at the speed rank. .

The speed rank according to the number of operated switch elements 27 and the speed rank according to the ratio of the operated switch elements are not limited to four steps, and the number of steps can be set arbitrarily. It goes without saying that when the number of stages is large, the width of the number or ratio of switch elements for each speed rank becomes relatively narrow. The speed rank for the speed determination unit 43 may be set on a dedicated screen, or may be selected and set from a plurality of preset patterns, or may be operated in advance in consideration of the thickness of the operator's finger. It is also possible to store the number of the switch elements 27 that the person touches with the fingertip 47 and turned on, and use that number as a criterion for determining the speed rank.

For example, the operator may be asked to perform the operations shown in FIGS. 5 to 8 in advance, and the intermediate value of the number of switch elements 27 turned on by each operation may be used as the boundary value for the speed rank determination. It is possible. In addition, the speed rank mentioned above is
For example, a speed for increasing or decreasing the set value in a certain fixed period is set. For example, if the value n is changed in a certain time in the speed rank 4, n × 2 in rank 3, n × 5 in rank 2, In No. 1, it is configured as n × 10, and the speed depending on the rank can be set arbitrarily.

The above-described embodiment of the present invention is an example in which the speed of increase or decrease of the rotation speed of the motor during image display is varied, but the present invention controls the speed of changing the set value during image display. Can be configured to For example, as shown in FIG. 9 showing the control device 11 equipped with the touch panel display device, in addition to the arrow key display 15b, the table display 15c, the function key display 15d, the shift key display 15e similar to FIG. This is a case where the set value down key 51 is arranged at the bottom of the screen with a set area wider than those of the keys 15b to 15e.

In the setting screen of FIG. 6, when setting data in each table display 15c, first, the location of the data to be set is designated directly by a finger or the position is designated by the arrow key display 15b and the main control section 33 is used. It is possible to make a designation judgment, and to raise or lower the set value by the set value raising key 49 or the set value lowering key 51, and create image data in which the set value is changed in speed by the speed signal from the speed confirming section 43. The main controller 33 may be formed so as to output.

In this case, the main controller 33 can externally output the set value to a control target (not shown) via the control device 11. It should be noted that the set values such as the temperature generally have an upper limit and a lower limit, and when the set values exceed the limit values, the set values are fixed to the limit values, as in the case of the above-described motor rotation speed.

Further, in the present invention, the image display section 37 by the main control section 33 is used in addition to individually changing the rotation speed of the motor and the rising or falling speed of the set value as an external movable section.
It is also applicable to variable control of the switching speed of the image display 15 in FIG. For example, when switching scanning between a plurality of operation screens 1 to n as shown in FIG. 3 and a plurality of setting screens and monitor screens 1 to m as shown in FIG. 9 at high speed, after setting the image switching mode by the function key display or the like. The image is switched by the set value increasing key 49 or the set value decreasing key 51, or the function key display 15d itself has a switching function.

As described above, in the present invention, the set value increasing key 4
In addition to 9 and the set value down key 51, the function key display 15d and the like can be used as the specific switch area.
Then, when it is desired to speed up the image switching, a wide area is touched with the fingertip 47 as shown in FIG. 5, and when it is desired to delay the image switching, a narrow area is touched as shown in FIG. The image display unit 37 via the control unit 35
The switching speed of the screen display 15 displayed on the screen can be changed.

When the image switching is slow, the individual image displays 15 associated with the image switching can be completely displayed.
When the image switching is fast, the display control unit 35 and the image display unit 37 cannot follow the display speed, and the complete image display 1
It is possible that 5 is not obtained. In this case, only a part of the image portion having a title or characteristic such as “setting screen 1” or “operation screen 1” is displayed for each image display, and the remaining image parts such as setting data and measurement data are displayed. The display may be performed after the fingertip 47 is separated from the set value up key 49 or the set value down key 51 or the image switching is delayed.

If the present invention is applied to the configuration in which the respective image displays 15 are switched in this way, when displaying a large number of image displays 15 by switching, it is not necessary to spend time searching as in the conventional case, and it is desired to display next. The operation up to image display is simplified. By the way, as described above, the specific switch area in the present invention includes the set value increase key 49 and the set value decrease key 51.
In addition to the function key display 15d and other key areas, the present invention has a configuration in which the changing speed can be changed by changing the area touched by the fingertip 47 or the like, so that the specific switch area is another key area. A larger area is preferable.

In addition, in the touch panel display device capable of producing sounds such as melody sounds, the main control unit 33 is modified so that the speed or direction of change or the speed of the sound or tone color or If you make the volume variable,
Since the operation status can be detected by sound, operability is improved. Furthermore, in the present invention, by changing and forming the main control unit 33, if it is formed so as to be able to change the color of the entire image display or a specific area and the density thereof by following the changing speed and the changing direction thereof, the image display can be changed. The operability at the time of changing the set value and changing the entire image display is improved. That is, in the present invention, the change of the image data from the main control unit 33 includes the change of the color and the shade thereof.

[0050]

As described above, according to the present invention, the image display section, the display control section for controlling the image display of the image display section based on the image data, and the plurality of switch elements turned on or off by the touch operation are provided. A touch panel unit that has a matrix shape and is stacked on the image display unit, a switch detection unit that detects a switch element that is turned on or off in the touch panel unit, and a detection switch in a specific region detected by the switch detection unit It has a speed determining unit that outputs a speed signal according to the number of elements, and a main control unit that outputs the image data to the display control unit and controls the changing speed of the image data according to the speed signal. It is possible to change the changing speed of a part or the whole of the display screen simply by adjusting the touch area to the area. Moreover, it is not necessary to continue watching by just checking the operation part such as the touch panel part, and it becomes easy to operate only by looking at the external movable part, the situation of the process, and the part of the quality of the product. The operability is improved because the operation speed can be changed like a jog shuttle. Further, since it is not necessary to use a dial operation knob or the like as in the conventional case, the configuration of the touch panel display device or the control device equipped with the touch panel display is not complicated, and the operation area is not easily expanded because only the touch panel portion is operated. Then, controlling the changing speed of the operation amount according to the speed signal from the speed fixing unit,
In the configuration in which the main control unit is formed to control the changing speed of the set value during image display and output the changing set value, and further to control the switching speed of the entire image display, the touch area of the touch panel unit The operation amount, the set value, and the changing speed of the image switching can be changed only by adjusting the. Further, if the main control unit is formed so as to output the sound changed according to the speed signal, there is an advantage that the changing speed can be surely detected only by listening to the sound output without looking at the image display unit.
