Description

  The present invention relates to a handy type operating device that can communicate with an industrial machine such as a machine tool, a loader, or a robot, and is used to manually operate an operation part of the industrial machine.

  There is a machine tool system that includes a machine tool such as a lathe and a loader that supplies and discharges workpieces to the machine tool. The machine tool system is normally operated by automatic control by a control device, but may be operated manually by interrupting the automatic control operation during teaching, maintenance, or the like. In such a manual operation, the machine is operated using a portable operating device that can be carried so that the operation parts of the machine tool and the loader can be confirmed in the vicinity.

  The conventional handy type operating device has a configuration shown in FIG. 6, for example. That is, the operation part selection switch 70 formed of a rotary switch is turned using the knob 70c, and the operation part of the machine tool or the loader is selected by matching the instruction part 70a with the operation part name display part 70b. When the selected operation part is a part that always performs a fixed operation such as a chuck or the like, the operation part operates by turning ON the operation buttons 71A and 71B. For example, when the operation part is a chuck, the chuck is opened when one operation button 71A is turned on, and the chuck is closed when the other operation button 71B is turned on. In addition, when the selected operation part is a part whose operation amount is variable such as an XYZ axis moving part of a loader, the dial type operation unit 72 is operated with one of the operation buttons 71A and 71B turned ON. By operating, a pulse corresponding to the operation amount is generated, and the operation part operates by the generated pulse. If the magnification of the pulse amount generated for each of the two operation buttons 71A and 71B is set differently, whichever of the two operation buttons 71A and 71B is turned on even if the operation amount of the dial type operation unit 72 is the same. Depending on how, the amount of motion of the motion part can be varied.

  If any one of the plurality of operation parts is selected by operating the dial type operation unit in a state where the second mode is selected by the mode switching means, another operation unit is not provided. Therefore, it is possible to select an operation part and to simplify the operation unit. In addition, when the selected operation part is displayed on the display unit, the selected operation part can be easily confirmed, and erroneous operation can be prevented. When the dial type operation unit and the display unit are provided in front of the case, the operation of the dial type operation unit and the visual recognition of the display unit are easy.

In the present invention, the mode switching means may change the first mode from the first mode when the dial type operation unit is operated beyond a predetermined operation amount or when it is operated beyond a predetermined time. The mode may be switched to the second mode.
As a result, it is possible to prevent an operation portion selection operation excessive operation that is operated by operation of the dial type operation unit.

The handy type operating device 1 will be described with reference to FIG.
The handy type operating device 1 has a case 1a having a size and shape that can be held with one hand as shown in the figure, and does not have the display unit 3 using a liquid crystal display or the like on the front side and the handy type operating device 1. A dial type operation unit 4 that is operated by one hand is provided. Further, left and right operation buttons 5A and 5B that can be operated by a hand having the handy type operating device 1 are provided on both side surfaces of the handy type operating device 1, respectively. The dial type operation unit 4 and the left and right operation buttons 5A and 5B are the operation units of the handy type operation device 1. In this embodiment, the display unit 3, the dial type operation unit 4, and the operation buttons 5A and 5B are all arranged at a place where the operator can see at the same time, but the operation buttons 5A and 5B are located at a place where the operator cannot see them. It may be arranged.

  On the display unit 3, operation part names of the industrial machine 20 that can be controlled by operating the handy type operating device 1 are displayed one by one. In this example, the displayed operation part names are “X-axis movement”, “Y-axis movement”, “Z-axis movement”, “first loader chuck”, “second loader chuck”, “first loader chuck”. And “second reversal chuck” (see FIG. 3). The names of these operation parts are as follows: the traveling table 34 of the industrial machine 20, the lifting rod 36, the front / rear moving table 35, the first loader chuck 38, the second loader chuck 39, the swivel table 40 a of the index mechanism 40, and the first. This corresponds to the reverse chuck 31 and the second reverse chuck 32, respectively.

  The dial type operation unit 4 performs a dial operation using the knob 4c. A scale 4a is attached to the outer periphery of the dial type operation unit 4, and the dial operation amount can be understood by reading the scale 4a whose position matches the mark 4b provided on the case 1a. The dial type operation unit 4 can be switched between two operation modes, and performs different work in each mode. In the first mode, by operating the dial type operation unit 4, a specific operation member among the plurality of operation parts is operated, and the operation amount is controlled. In the second mode, by operating the dial type operation unit 4, an operation part where the control is effective is selected. Switching between the first mode and the second mode is performed by the left and right operation buttons 5A and 5B.

  The operation buttons 5A and 5B are of a push button type, and the pushed state is ON, and the returned state is OFF. Both the left and right operation buttons 5A and 5B can be turned off, but both are not turned on. For example, the operation buttons 5A and 5B are pushed in by being pushed with a finger or the like, and when the finger or the like is released, the operation buttons 5A and 5B are automatically returned to their original positions by the action of a built-in spring member or the like (not shown). The operation buttons 5 </ b> A and 5 </ b> B may have a structure in which the operation buttons 5 </ b> A and 5 </ b> B are kept pressed when pressed once and return to their original positions when pressed again.

  The operation buttons 5A and 5B have three functions. The first function is to switch the operation mode of the dial type operation unit 4 between the first mode and the second mode. When any one is ON, the first mode is set, and both are OFF. Sometimes it becomes the second mode. The second function is to operate an operation part that always performs a fixed operation among the operation parts of the industrial machine 20. This function functions for the selected operation part, that is, the operation part displayed on the display unit 3. The third function is to specify the magnification of the pulse that gives the operation command when operating the operation part of the operation part of the industrial machine 20 in which the operation amount is variable. This function will be described in detail later.

  FIG. 2 is a block diagram showing a schematic configuration of a control system of the handy type operating device 1. Based on information from dial type operation unit 4 and operation buttons 5A, 5B, command generation unit 10 generates a command to be sent to manual operation control unit 52 and display unit 3 of overall control device 50 (FIG. 1). The command generation unit 10 includes a custom AISC (an integrated circuit manufactured specifically for a specific application), a microcomputer, an FPGA (Field Programmable Gate Array), and other electronic components, and includes a mode switching unit 11 and an operation site selection unit 12. , A selection operation part command means 13, an axis / pulse determination means 14, a pulse generation means 15, a destination switching means 16, and a display content generation means 17.

  The mode switching means 11 determines whether the operation buttons 5A and 5B are ON or OFF, and the operation mode of the dial type operation unit 4 is set to the first mode as described above according to the determination result. And the second mode. Again, when one of the operation buttons 5A and 5B is ON, the first mode is selected, and when both are OFF, the second mode is selected.

The mode switching means 11 includes an operation amount detection means (not shown) for detecting the operation amount of the dial type operation unit 4 and an operation time detection means (not shown) for detecting the operation time of the dial type operation unit 4. have. The mode switching means 11 is operated when the dial type operation unit 4 is operated exceeding a predetermined operation amount or when the dial type operation unit 4 is operated beyond a predetermined time. The operation mode of the unit 4 is automatically switched from the first mode to the second mode. Thereby, it is possible to prevent the operation part selection operation excessive operation that is operated by the operation of the dial type operation unit 4.
The operation mode of the dial type operation unit 4 is changed to the first mode only when the mode switching unit 11 has only the operation amount detection unit and the dial type operation unit 4 is operated beyond the predetermined operation amount. The configuration may be such that the mode is automatically switched to the second mode. Alternatively, the operation mode of the dial type operation unit 4 is changed to the first operation mode only when the mode switching unit 11 has only the operation time detection unit and the dial type operation unit 4 is operated beyond a predetermined time. The configuration may be such that the mode is automatically switched to the second mode.

  Further, in some cases, the operation buttons 5A and 5B may not be provided. In that case, mode switching by the operation of the operation buttons 5A and 5B is not performed, and only the automatic mode switching based on the operation amount or operation time of the dial type operation unit 4 is performed.

  When the dial-type operation unit 4 is operated when the operation mode of the dial-type operation unit 4 is the second mode, the operation site selection unit 12 selects one of the operation sites according to the operation amount. select. For example, assuming that the operation parts are registered in the order shown in FIG. 3, assuming that the currently selected action part is “Y-axis movement”, turning the dial type operation unit 4 in the forward rotation direction by a certain angle will result in “Z “Axis movement” is selected, and when the dial type operation unit 4 is further rotated in the forward rotation direction by a certain angle, “first loader chuck” is selected. When the dial type operation unit 4 is rotated in the reverse rotation direction, the operation part is selected in the reverse direction of the registration order. The order of registration of the operation parts shown in FIG. 3 is an example, and is not limited to this. It is desirable to determine the registration order so that the operation amount of the dial type operation unit 4 can be reduced as much as possible in accordance with the actual operating status of the industrial machine 20.

  The selected action part designating unit 13 receives the ON signal of the operation buttons 5A and 5B in a state in which the action part that always performs the action determined by the action part selecting unit 12 is selected. The first loader chuck control means 58, the second loader chuck control means 59, the index control means 60, the first reverse chuck control means 61, and the second reverse chuck control of the manual operation control unit 52 so as to operate. A command is output to any of the means 62. For example, when the operation part is the chuck 31, 32, 38, 39, the opening operation is performed when the left operation button 5A is ON, and the closing operation is performed when the right operation button 5B is ON. When the operating part is the swivel base 40a of the index mechanism 40, when the left operation button 5A is ON, the first loader chuck 38 is set to the front posture, and when the right operation button 5B is ON. Makes the second loader chuck 39 the front posture.

  The axis / pulse determination means 14 is a destination of the pulse when the pulse generation means 15 generates a pulse as will be described later when the movement part whose movement amount is variable is selected by the movement part selection means 12. And means for determining the number of pulses. The destination of the pulse is the motion part selected by the motion part selection means 12. The number of pulses is a value obtained by multiplying the number of pulses determined for each operation region by a magnification determined according to the ON / OFF signals of the operation buttons 5A and 5B. For example, when the left operation button 5A is ON, the magnification is 1 ×, and when the right operation button 5B is ON, the magnification is 10 ×.

  When the dial type operation unit 4 is operated in the state where the operation mode of the dial type operation unit 4 is the first mode, the pulse generation unit 15 sets the number of pulses determined by the axis / pulse determination unit 14 to the dial type. The number of pulses multiplied by a coefficient proportional to the operation amount of the operation unit 4 is generated. When the dial type operation unit 4 is operated in the forward rotation direction, a pulse for moving the operation part in the positive direction is generated, and when the dial type operation unit 4 is operated in the reverse rotation direction, the operation part is negative. A pulse that moves in the direction of is generated.

  The destination switching means 16 is a means for switching the pulse transmission circuit so that the pulse generated by the pulse generating means 15 is sent to the operation part determined by the axis / pulse determining means 14. The pulse generated by the pulse generation unit 15 is sent to any of the X-axis movement control unit 55, the Y-axis movement control unit 56, and the Z-axis movement control unit 57 of the manual operation control unit 52 via the destination switching unit 16. Sent.

  The display content generation unit 17 is a unit that generates a display content command to be displayed on the display unit 3 from the information on the operation site selected by the operation site selection unit 12. The command generated by the display content generation means 17 is sent to the display unit 3, and the selected operation site is displayed by characters on the display unit 3 as shown in FIG. You may display a selection operation | movement part on the display part 3 with a figure.

Manual operation of the industrial machine 20 by the handy type operating device 1 is performed as follows.
For example, when the loader head 37 of the loader 22 is moved in the X-axis, first, the dial type operation unit 4 is turned with the operation buttons 5A and 5B being both OFF to display “X-axis movement” on the display unit 3. . Next, in a state where any one of the operation buttons 5A and 5B is pressed and turned on, the dial type operation unit 4 is turned by an angle corresponding to the moving amount in a direction corresponding to the moving direction. As a result, the loader head 37 moves along the X axis. At this time, the magnification of the movement amount of the loader head 37 with respect to the operation amount of the dial type operation unit 4 can be selected in one of two ways depending on which of the operation buttons 5A and 5B is turned ON. If a higher magnification is selected when moving a long distance, the operation amount of the dial type operation unit 4 can be reduced and the operation becomes easy.

  For the Y-axis movement and the Z-axis movement, the same operation as described above is performed except that the operation part name displayed on the display unit 3 is “Y-axis movement” or “Z-axis movement”. For any of the axis movements, the loader 22 is not intended due to an erroneous operation because the axis movement is not performed even if the dial type operation unit 4 is operated unless the conscious operation of pressing the operation buttons 5A and 5B is performed. It is possible to prevent movement.

  When opening and closing the first loader chuck 38, first, the dial type operation unit 4 is turned with the operation buttons 5 </ b> A and 5 </ b> B both being OFF to display “first loader chuck” on the display unit 3. In this state, when the left operation button 5A is turned on, the first loader chuck 38 is opened, and when the right operation button 5B is turned on, the first loader chuck 38 is closed. The other chucks 31, 32, 39 are also opened and closed by the same operation as described above.

  In order to switch the front posture and the downward posture of the first and second loader chucks 38 and 39, first, the dial type operation unit 4 is turned with the operation buttons 5A and 5B both turned OFF, and an “index” is displayed on the display unit 3. "Is displayed. In this state, when the left operation button 5A is turned on, the first loader chuck 38 is in the front posture and the second loader chuck 39 is in the downward posture. When the right operation button 5B is turned on, the first loader chuck 38 is turned on. The loader chuck 38 is in the downward posture and the second loader chuck 39 is in the front posture.

  Thus, by providing the two operation modes of the first mode and the second mode in one dial type operation unit 4, only the dial type operation unit 4 and the operation buttons 5A and 5B are used. Each operation part can be operated. Since the number of operation units is small, the operation is simple. Moreover, since the selected operation | movement site | part is displayed on the display part 3, the selected operation | movement site | part can be confirmed easily and an erroneous operation can be prevented. Since the display unit 3 is disposed in front of the case 1 a visible to the operator together with the dial type operation unit 4, it is easy to see the display content of the display unit 3 even when the dial type operation unit 4 is operated.

  In this embodiment, the manual operation by the handy type operating device 1 is limited to the operation related to the transfer of the workpiece W by the loader 22, but the machine tool 21 may be operated by the operation of the handy type operating device 1.

  Further, in this embodiment, when the operation mode of the dial type operation unit 4 is the second mode, an operation part in which the control is effective is selected, but other work may be performed. For example, by operating the dial type operation unit 4 in the second mode, the light quantity, color, etc. of illumination in the machine tool 21 may be changed, or analog operation such as mouse operation on the operation panel, specifically, May be able to perform an operation of moving the cursor on the screen instead of the mouse.

The industrial machine 20 is not limited to a machine tool system in which the machine tool 21 and the loader 22 are combined, and may be the machine tool 21 alone or the loader 22 alone.
The technique of the handy type operating device 1 can be applied to other industrial machines such as robots.
