DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. The machine control device using the touch panel is used when the servo mechanism 2 of the controlled machine 1 to be numerically controlled is manually operated. Controlled machine 1

Machines used in the production and transport of goods, such as machine tools, plate processing machines, and transport machines. The servo mechanism 2 includes a movable body 3
For driving the position controllable, and comprises a drive source and its controller. In this embodiment, the servo mechanism 2 includes a servo motor 4 serving as a drive source and a servo controller 5 for driving the movable body 3 through a feed mechanism 6 such as a ball screw mechanism by driving the servo motor 4. Can be The overall control device 7 is a means for controlling the entirety of the controlled machine 1, is configured by a computer device such as a personal computer, and includes an automatic operation control unit 8 and a manual operation control unit 9. The automatic operation and the manual operation can be switched by a mode switch (not shown) or the like. The automatic operation control unit 8 includes an operation program 10 such as a machining program.
In accordance with the formula (1), a control command is given to the servo controller 5 as one of the control commands.

The manual operation control section 9 is means for controlling the servo mechanism 2 by manual operation, and uses the touch panel 11 as an input device. The touch panel 11 is provided with a transparent digitizer overlaid on a display so that an instruction can be input by a finger or the like. The touch panel 11 is used for various inputs by changing its screen display contents in various ways. Hereinafter, a case where the touch panel 11 is used for controlling the servo mechanism 2 by manual operation will be described. Manual operation control unit 9
Comprises a screen display means 12 and an operation recognition movement command means 13.

The screen display means 12 is a means for displaying an input operation unit 19 for manual operation of the servo mechanism 2 on the display of the touch panel 11 on a screen. The input operation unit 19
A plurality of touch switch displays 20 are arranged so that input operation can be continuously performed by tracing with a finger. Each touch switch display 20 is arranged in a circle. The operation recognition movement command means 13 is a means for giving a movement command s to the servo mechanism 2 of the controlled machine 1 in accordance with an input operation of the input operation unit 19 of the touch panel 11. The movement command s is composed of a pulse train and is input to the servo controller 5.

The operation recognizing movement commanding means 13 is for recognizing an input on the touch panel 11 and judges that an input has been made when a range corresponding to the input operation section 19 is touched with a finger or the like. When the input operation unit 19 includes a row of the touch switch displays 20, every time any part of each touch switch display 20 is touched, a predetermined coordinate input set in advance corresponding to the touch switch display 20 is performed. It is recognized that there was. Note that the operation recognition movement command means 13
Instead of using the coordinate values determined for each touch switch display 20 as described above, the touched coordinate position may be directly recognized as input coordinates. In this case,
The touch switch display 20 serves to display an indication of a range in which an input is recognized.

The operation recognizing movement commanding means 13 includes, in addition to the means for performing input recognition described above, a moving command providing means 14, a direction determining means 15, a speed determining means 16, and an operation continuity recognizing means 1.
7 and a discontinuous stop means 18 for performing, for example, the control shown in the flowchart of FIG.

The movement command applying means 14 is provided for the touch panel 1
1 is a means for recognizing a change in the input coordinates and giving a movement command s to the servo controller 5 based on the change. In the case of the processing of FIG. 2, it is a means for issuing a normal rotation command and a reverse rotation command in steps S2 and S6. In addition, the movement command giving means 14
As the movement command s, a movement amount according to the change amount of the input coordinates of the touch panel 11 is commanded. For example, touch panel 1
In the case where one input operation unit 19 is composed of an array of touch switch displays 20, the movement command giving unit 14 generates a predetermined number of pulses by moving the traced position by one touch switch display 20. You. Note that the movement amount of the movement command s by the movement command applying means 14 is the same as that of the touch panel 1.
It may be determined based on the time during which one input operation unit 19 is touched. For example, the movement command s may be given so that the movement continues for a time during which the input operation unit 19 is touched. The direction determining means 15 is means for controlling the axial direction as forward rotation when the input coordinates increase, and reverse rotation when the input coordinates decrease, and in the processing of FIG.
1, S5. The speed determining means 16 is a means for monitoring the increase amount of the input coordinates and changing the feed speed according to the amount, and corresponds to steps S3 and S4 in the processing of FIG. In this case, the increment of the input coordinates is the increment of the input coordinates per unit time. The speed determining means 16
The feed speed may be changed according to the increment of the input coordinates each time one continuous input operation is performed from the touch panel 11 instead of the increment of the input coordinates per unit time. In this case, for example, the movement command providing means 14 may determine the movement amount based on the time during which the input operation unit 19 is touched as described above, or move by a fixed movement amount by one input operation. You may do it.

The operation continuity recognizing means 17 is a means for monitoring a change in coordinate input on the touch panel 11 and determining whether or not the input operation has lost continuity under a predetermined condition.
The process of FIG. 2 corresponds to the process of performing the determination of step S7 through steps S1 and S5. This series of processes is a process of moving to the next stop command S8 when the coordinate input on the touch panel 11 does not increase or decrease, that is, when the input coordinates are stopped or there is no input for a certain period of time or longer. is there. In addition to the above, the operation continuity recognizing unit 17 may determine that the continuity has been lost, for example, when the increase width or the decrease width of the input coordinates is equal to or more than a certain value, or after the input coordinate increase / decrease direction is reversed. It is assumed that it is reversed again. When the operation continuity recognition unit 17 determines that the operation is discontinuous,
This is a means for issuing a stop command. In the example of FIG.
Is applicable. The time at which the stop command is issued is, for example, a certain time after it is determined that the operation is discontinuous. The operation-recognition-movement instructing means 13 includes, in addition to these means, means (not shown) for correcting input coordinates according to a predetermined rule in accordance with the display on the input operation unit 19 of the touch panel 11. Correction when the touch switch displays 20 of the input operation unit 19 are arranged in a circle will be described later.

FIG. 4 shows an example of the machine 1 to be controlled. In this example, the controlled machine 1 is a turret type lathe, and the feed base 22 on which the turret 21 is mounted corresponds to the movable body 3 in the example of FIG. The feed stand 22 is installed so as to be movable on a guide 24 of a bed 23 in a direction approaching and separating from a spindle 26 of a headstock 25, and is provided with a feed mechanism 6 such as a ball screw mechanism.
Is driven forward and backward by the servo motor 4 via the.

The operation of the above configuration will be described. First, the outline will be described. Each touch switch display 20 on the touch panel 11
Is successively touched by the operator with the finger 30 or the like, so that the operation recognition movement command means 13 gives a movement command s based on a pulse train to the servo controller 5. The servo controller 5 drives the servo motor 4 according to the movement command s to move the movable base 3. When the touch switch displays 20 are arranged in a circle as shown in the drawing, the operation recognition is performed by touching an arbitrary touch switch display 20 and sequentially tracing each touch switch display 20 with a finger 30 so as to draw a circle or an arc. The movement command means 13 recognizes in which direction the signal obtained for each touch of each touch switch display 20 is being rotated to determine the movement direction,
A movement command s for driving in a direction corresponding to the moving direction is output. If the speed at which the finger 30 contacts the plurality of touch switch displays 20 is different, the speed at which a pulse serving as the movement command s is output is also different. As a result, the rotation speed of the servomotor 4 is changed. A function equivalent to that of a manually configured pulse generator is realized on the touch panel 11.

The operation will be described with reference to the flowchart of FIG. FIG. 7 is a diagram showing the processing of the operation recognition movement command means 13 of FIG. 1 as described above. As the touch switch display 20 is traced, it is determined whether the coordinate values sequentially input from the touch panel 11 are increasing or decreasing (S1, S1).
5) In the case of an increase, the rotation is recognized as a forward rotation, and a forward rotation movement command s is output (S2). In the case of decrease, a reverse rotation command s recognized as reverse rotation is output (S6).
The movement amount of the movement command s is determined, for example, such that a predetermined number of pulses are generated when the input moves by one touch switch display 20. Further, a change amount of the input coordinate value per unit time is recognized (S3), and a speed command corresponding to the change amount is generated (S4). This speed command may be output to the servo controller 5 as a speed command such as a digital value or an analog value. However, in this embodiment, in steps S2 and S6, a pulse train given as a forward or reverse movement command s is provided. It is given as a pulse interval.

If the coordinate values inputted from the touch panel 11 are neither increased nor decreased, for example, if the same coordinate values are continuously inputted or there is no input, it is determined whether or not the state continues for a predetermined time. (S7) If it continues for a certain period of time, a stop command is output assuming that the continuity of the input operation has been lost (S8). The stop command is given, for example, by stopping the output of a pulse train serving as the movement command s. If the predetermined time does not continue, the process returns from the determination step S7 to the first step S1, and the processing of FIG. 2 is repeated.

When it is determined by the operation continuity recognizing means 17 of FIG. 1 that the continuity of the operation has been lost, in addition to the above case, the increase width, that is, the amount of increase or decrease of the input coordinates per unit time Is greater than or equal to a predetermined value, and the directions of increase and decrease of input coordinates may change two or more times. When the direction of the increase and decrease of the input coordinates changes more than twice, for example,
When the tracing direction of the touch switch display 20 is after the forward direction,
This is the case where the direction changes to the negative direction and then changes to the positive direction again.

In the case where the touch switch displays 20 are arranged in a circle, if the input coordinate values are processed as they are, if the operation is performed in a circular manner, the input coordinate values are repeatedly increased and decreased many times. Therefore, the direction is not determined in the processing of FIG. Therefore, as shown in FIG.
With the center of the circle C on which the touch switch displays 20 are arranged as the coordinate origin, the coordinates are divided into four quadrants R1 to R4, and the increase and decrease are reversed depending on which quadrant R1 to R4 the touched touch switch display 20 is located in. Correction to be performed.
For example, if the operation of tracing the circle C in the direction of the arrow in FIG. 3 is in the positive direction (increase direction), in the first quadrant R1 and the second quadrant R2, the direction in which the X coordinate increases is set as the increase direction. , In the third and fourth quadrants R3 and R4,
The direction in which the X coordinate decreases is corrected as the increasing direction. Thus, an appropriate correction process is performed according to the arrangement of the touch switch displays 20.

In the above embodiment, the touch switch display 20
Are described in the case of being arranged in a circle, but as shown in FIG. 5, the input operation unit 19 of the touch panel 11 may be one in which the touch switch displays 20 are arranged in a straight line. May be an array. That is, the touch switch display 20 only needs to be an array that allows continuous input operation by tracing with a finger. As shown in an example in FIG. 6, a target machine diagram display 31 is provided on the screen of the touch panel 11, in which the operation target portion of the control target machine 1 is shown in a diagram or a picture, and input in correspondence with the target machine diagram display 31. The operation unit 19 may be displayed. The input operation unit 19 may be an array of the touch switch displays 20 or another display. The whole or a part of the target machine diagram display 31 itself may be used as the input operation unit. For example, a state in which the display unit 31a (in the illustrated example, the display unit corresponding to the feed plate 22 in FIG. 4) of the machine part to be moved by manual operation in the target machine diagram display 31 is set as an input operation unit, and the input operation unit is touched. It is also possible to give a coordinate input by tracing the finger in the desired movement direction with.
