  The present invention relates to a part program selection device, an industrial machine, and a part program selection method used when performing processing of a measuring machine or the like.

2. Description of the Related Art Conventionally, a measurement apparatus that performs measurement processing on a workpiece placed on a table is known (see, for example, Patent Document 1).
In the apparatus described in Patent Document 1, a work is fixed to a fixing jig, and the fixing jig is placed on a table. The jig is provided with a jig discrimination forming unit, and the measuring apparatus automatically selects a part program corresponding to a measurement process performed on the workpiece by measuring the jig discrimination forming unit.

Japanese Patent Laid-Open No. 9-178469

By the way, in an industrial machine that performs various types of processing such as measurement processing on workpieces, the operator must specify the optimum part program corresponding to the processing to be performed after placing the workpiece on the table. If the designation is wrong, accurate processing (measurement and processing) cannot be performed. Since a plurality of part programs are created according to, for example, the type of work, the operator needs to select an appropriate part program from the plurality of part programs, which is a complicated operation.
In addition, in a manufacturing site or the like, it is common to place a workpiece fixed on a jig on a table and perform measurement or processing on the workpiece. The jig to which the workpiece is fixed is the same or approximately the same every time. There is a tendency to be installed at the same position. In such a case, finding the part program corresponding to the workpiece measurement and machining position from all the part programs each time is very complicated and causes an erroneous operation.

  Here, in the apparatus described in Patent Document 1, a part program is automatically selected by measuring a jig discrimination forming portion provided in a fixing jig for fixing a workpiece. However, in this case, since it is necessary to separately prepare a plurality of jigs corresponding to the type of workpiece and the type of measurement, there is a problem that the cost is increased. Moreover, since it is necessary to install the fixing jig to which the workpiece is fixed at a predetermined position on the table, the degree of freedom in performing the measurement is reduced.

The Z drive mechanism 143 is a mechanism that moves the Z slider 142 in the Z direction. Although not shown, the Z drive mechanism 143 is constituted by, for example, a Z-axis feed screw mechanism having a ball screw shaft extending in the Z direction and a nut member screwed to the ball screw shaft. Can do. The feed screw mechanism can be constituted by, for example, a Z-axis drive motor and a Z-axis rotation transmission mechanism that transmits the rotation of the Z-axis drive motor to the ball screw shaft. As the Z drive mechanism 143, a Z adjustment knob 143A may be provided as shown in FIG. The Z adjustment knob 143A is connected to one end of the above-described ball screw shaft, and manually rotates to rotate the ball screw shaft.

The X drive mechanism 146 is provided with an X scale 148 (see FIG. 2) for detecting the position of the X slider 145 in the X direction.

[Configuration of control device]
FIG. 2 is a block diagram showing an outline of the system configuration of the surface texture measuring instrument 1.
The control device 20 can be configured by a computer such as a personal computer, for example, and corresponds to the part program selection device of the present invention. The control device 20 includes a storage unit 21, an operation unit 22, and a control unit 23.

The storage unit 21 stores various programs and various data for controlling the driving of the surface texture measuring machine 1.
As various programs stored in the storage unit 21, a part program including a measurement procedure for performing measurement processing on the workpiece W is stored. A plurality of part programs are stored in accordance with the type of the workpiece W, the measurement position with respect to the workpiece W, and the like. Note that these part programs are created in advance and stored in the storage unit 21.
Also, in each of these part programs, process start position information indicating the position of the detector 13 that starts the measurement process is stored in association with the position information. Here, the processing start position information is the (X, Z) coordinate position of the coordinate system of the apparatus main body 10 detected by the Z scale 147 and the X scale 148. For example, the position coordinates of the detector 13 are acquired at the time of creating each part program, and the process start position information is associated with the process start position information of the created part program.
In addition, table data that records the relationship between the program ID for identifying each part program and the processing start position information may be recorded.

The operation unit 22 includes a mouse, a keyboard, a joystick, and the like, for example, and outputs an operation signal to the control unit 23 when operated by an operator.
The control unit 23 includes, for example, an arithmetic circuit such as a CPU (Central Processing Unit), a storage circuit, and the like, and reads and executes a program stored in the storage unit 21, as shown in FIG. It functions as an acquisition unit 231, a selection unit 232, a designated program acquisition unit 233, an operation control unit 234, and a display control unit 235.

The position acquisition unit 231 acquires the position of the detector 13 of the apparatus main body 10. The position acquisition unit 231 acquires the position of the detector 13 in the Z direction detected by the Z scale 147 of the apparatus main body 10 and the position of the detector 13 in the X direction detected by the X scale 148.
The selection unit 232 extracts (selects) the part program associated with the processing start position information indicating the position of the detector 13 acquired by the position acquisition unit 231 from the storage unit 21.

The designated program acquisition unit 233 performs measurement that causes the apparatus main body 10 to execute the part program included in the operation signal when an operation signal for designating the part program is input by operating the operation unit 22 by the operator. Acquired as a part program (execution part program) including a measurement procedure of processing.
The operation control unit 234 reads the execution part program acquired by the designated program acquisition unit 233 from the storage unit 21 and executes it. As a result, a measurement control signal including a measurement procedure is transmitted from the control device 20 to the device main body 10, and measurement processing for the workpiece W is performed in the device main body 10.

  The display control unit 235 controls the display device 30 to display image information indicating the part program on the screen of the display device 30. At this time, the display control unit 235 may display image information corresponding to only the part program selected by the selection unit 232, and after displaying image information corresponding to a plurality of part programs, respectively, Image information corresponding to the part program selected by H.232 may be highlighted.

[Operation of surface texture measuring instrument 1]
Next, a method for measuring the workpiece W (part program selection method) by the surface texture measuring machine 1 as described above will be described.
FIG. 3 is a flowchart showing the measurement method in the present embodiment.
In this embodiment, when measuring a predetermined measurement position of the workpiece W, first, the workpiece W is set (placed) on the table 12. At this time, the work W may be fixed on a fixing jig or the like and then placed on the table 12.
Thereafter, the apparatus main body 10 drives the Z drive mechanism 143 and the X drive mechanism 146 to move the detector 13 to a place (processing start position) where the workpiece W measurement process is performed (step S1). In step S <b> 1, the apparatus main body 10 drives the drive motors of the Z drive mechanism 143 and the X drive mechanism 146 based on the operation of the controller of the operator (measurer) to move the detector 13. Note that the detector 13 may be moved to the processing start position by the operator adjusting the Z adjustment knob 143A or the X adjustment knob 146A.
FIG. 4 is a diagram showing the detector 13 moved in step S1. In the example of FIG. 4, the detector 13 is moved from a predetermined origin position (X0, Z0) = (0, 0) to positions X = X1 = 10 (mm) and Z = Z1 = 5 (mm). Yes.

  When the detector 13 is moved in step S1, the Z scale 147 measures the position of the detector 13 in the Z direction, and the X scale 148 measures the position of the detector 13 in the X direction. Position information indicating the measured position ((x, z) coordinates) of the detector 13 is transmitted from the apparatus main body 10 to the control apparatus 20. Thereby, the position acquisition unit 231 acquires (specifies) the position of the detector 13 from the position information transmitted from the apparatus main body 10 (step S2; position acquisition step). Therefore, in the example of FIG. 4, the position acquisition unit 231 can specify the position of the detector 13 as X1 = 10 (mm) and Z1 = 5 (mm).

When the position of the detector 13 is specified in step S <b> 2, the selection unit 232 selects a part program that uses the position of the detector 13 as processing start position information from a plurality of part programs stored in the storage unit 21. (Step S3: Selection step).
Since each part program stores processing start position information in association with each other, the selection unit 232 starts processing the same or substantially the same position as the position of the detector 13 acquired by the position acquisition unit 231. Select a part program to include as position information. Specifically, the selection unit 232 selects a part program corresponding to the processing start position in the first distance range set in advance from the position of the detector 13.
When the storage unit 21 stores table data indicating the correspondence between each part program and the processing start position information for each part program, the selection unit 232 selects the part program from the table data. May be.

After step S3, the selection unit 232 determines whether there is one part program selected in step S3 (step S4).
In step S4, when there is one selected part program (in the case of Yes), the process proceeds to step S7 to be described later with the part program as an implementation part program.

On the other hand, when it determines with No in step S4, the display control part 235 displays the part program selected by step S3 on the screen of the display apparatus 30 (step S5).
FIG. 5 is a diagram illustrating an example of the display screen 31 of the display device 30 displayed in step S5.
As described above, the selection unit 232 selects, from the position of the detector 13, a part program that includes the position of the preset first distance range as the processing start position information. For this reason, there may be a case where a plurality of part programs whose processing start position information is different within the first distance range are acquired. In this case, the display control unit 235 displays a program name 32 (image information) corresponding to the selected plurality of part programs on the display screen 31 of the display device 30, as shown in FIG.
Specifically, the display control unit 235 executes part programs having different processing start positions in the X direction along the screen horizontal direction (x direction: corresponding to the second direction of the present invention) on the display screen 31 of the display device 30. The program name 32 shown is displayed. Further, along the screen vertical direction (y direction: corresponding to the fourth direction of the present invention) on the display screen 31 of the display device 30, a program name 32 indicating a part program having a different processing start position in the Z direction is displayed. At this time, the part program with the smaller X coordinate of the processing start position is arranged with the program name 32 on the left side (−x side), and the part program with the smaller position in the Z direction (Z coordinate) of the processing start position is the program name. 32 is arranged on the lower side (+ y side) of the screen.
As a result, the program name 32 of the part program is displayed on the display screen 31 in a positional relationship corresponding to the processing start position, so that the operator can easily confirm the desired part program. .
Further, the display control unit 235 displays an instruction image 33 for designating a part program on the display screen 31.

Thereafter, the designated program acquisition unit 233 acquires a part program for performing the measurement process based on the operation signal from the operation unit 22 (step S6).
Specifically, on the display screen 31 as shown in FIG. 5, the operator operates the operation unit 22 to move and select the instruction image 33 onto the program name 32 corresponding to the desired part program. As a result, an operation signal for designating a predetermined part program is input from the operation unit 22 to the control unit 23. The designated program acquisition unit 233 identifies the implementation part program based on the operation signal.

  After step S6 or after determining Yes in step S4, the operation control unit 234 executes the implementation part program and outputs a control signal to the apparatus main body 10 (step S7). Thereby, in the apparatus main body 10, the detector 13 moves according to the measurement procedure specified by the part program, and the measurement process for the workpiece W is started. In addition, when the position of the detector 13 and the processing start position are slightly different, the difference value between the position of the detector 13 and the processing start position is calculated, and after moving the detector 13 by the difference value, Measurement processing based on the part program may be performed.

[Operational effects of this embodiment]
The surface texture measuring instrument 1 according to the present embodiment includes an apparatus main body 10 and a control device 20, and the apparatus main body 10 includes a table 12 on which the workpiece W is installed and a detector for measuring the workpiece W. 13. In addition, the control device 20 includes a storage unit 21 in which a plurality of part programs for performing measurement processing on the workpiece W are stored. Then, the control device 20 acquires the position of the detector 13 of the apparatus body 10 by the position acquisition unit 231, and the part associated with the processing start position information indicating the acquired position of the detector 13 by the selection unit 232. Select a program.
As a result, only the part program corresponding to the position of the detector 13 is selected, and no part program at any other position is selected, so that the operator can perform measurement processing of the workpiece W from the selected part program. A desired part program can be easily found. In particular, in a manufacturing site such as a factory, when performing measurement processing on the same workpiece W, the workpiece W tends to be installed at a predetermined position on the table 12, and the processing start position is also substantially the same position. In this embodiment, since the part program based on the processing start position is selected, it is particularly advantageous at the manufacturing site as described above, and the operability can be improved by assisting the operator to easily select the part program, In addition, mistakes in selecting part programs can be suppressed.

  In addition, if a discriminating section that designates a part program is provided in a fixture that fixes the workpiece W, it is necessary to form a plurality of fixtures corresponding to the type of each workpiece W. It is necessary to create a separate program to do this. In such a case, it is necessary to create not only the part program but also a fixing jig corresponding to the part program, and it is also necessary to construct a system configuration for determining the fixing jig determination unit. On the other hand, in this embodiment, the process start position information may be stored in association with the part program, and the configuration can be simplified.

  In the present embodiment, the position acquisition unit 231 acquires the position of the detector 13 (processing start position) when the detector 13 performs the workpiece W measurement process. Therefore, the part program is selected by the selection unit 232 and can be narrowed down by performing an operation that is normally performed when performing the measurement process on the workpiece W, that is, an operation of moving the detector 13 to the processing start position. . Therefore, it is not necessary to perform a dedicated operation for selecting (narrowing down) part programs, and the operator can easily find a desired part program.

  In the present embodiment, the display control unit 235 displays the program name 32 indicating the part program selected by the selection unit 232 on the display screen 31 of the display device 30. Therefore, the operator can easily find a desired part program for performing the measurement process on the workpiece W from the program name 32 displayed on the display screen 31.

In the present embodiment, the selection unit 232 selects a part program corresponding to the processing start position within the first distance range from the position of the detector 13.
For this reason, even when the position of the detector 13 is slightly different from the position indicated by the processing start position information associated with the part program, a desired part program can be selected.
In addition, when a plurality of part programs are selected by the selection unit 232, the display control unit 235 places the program name 32 on the left side (−x side) of the part program having a smaller X coordinate of the processing start position, As the part program has a smaller Z coordinate at the processing start position, the program name 32 is arranged on the lower side of the screen (+ y side). As a result, the program names are displayed in the order of the process start positions, and the operator can more easily find a desired part program corresponding to the measurement process, thereby further improving the operability.

In the present embodiment, the designated program acquisition unit 233 acquires one of the part programs selected by the selection unit 232 as an execution part program based on the operation signal from the operation unit 22. Then, the operation control unit 234 drives the detector 13 of the apparatus main body 10 based on the execution part program.
That is, when a desired part program is designated from the part programs narrowed down by the selection unit 232, processing based on the part program is performed. Thereby, the desired measurement process with respect to the workpiece | work W can be implemented easily and appropriately.

[Modification]
Note that the present invention is not limited to the above-described embodiments, and modifications and the like within a scope not departing from the object of the present invention are included in the present invention.
For example, in the above-described embodiment, the example in which the industrial machine of the present invention is applied to the surface texture measuring machine 1 has been described. However, the industrial machine can be applied to various measuring machines for measuring the size or shape of an article. it can. For example, the present invention can be suitably applied to a three-dimensional measuring machine that measures the position of each point on the surface of the article, a roundness measuring machine that measures the roundness of an article such as a cylinder.

Moreover, although the detector 13 which has the stylus 133 which measures the surface property of the workpiece | work W by contacting with respect to the workpiece | work W as an action | operation part was illustrated, it is not limited to this. For example, a laser beam transmitting / receiving unit is provided as an operation unit, and the shape of the workpiece W is measured by detecting the amount of laser light reflected by the workpiece W. The present invention can also be applied to a non-contact type measurement unit that measures the shape of the workpiece W based on the image.
Further, the operating unit is not limited to the one that inspects and measures the workpiece W, and may be, for example, a processing unit that performs processing such as polishing and cutting of the workpiece W. That is, the industrial machine is not limited to the measuring machine as described above, and can be applied to a processing machine for processing an article.

  In the above-described embodiment, an example in which the device main body 10, the control device 20, and the display device 30 are configured as separate bodies has been described. However, for example, a configuration in which a display unit is provided on the drive main body 144 or the like may be provided. It is good also as a structure etc. which incorporate the control apparatus 20 in the apparatus main body 10. FIG.

  In the above embodiment, the position acquisition unit 231 has shown an example in which the position of the detector 13 is acquired based on the detection signal output from the Z scale 147 or the X scale 148 of the apparatus body 10, but is not limited thereto. . For example, the position acquisition unit 231 may acquire the position of the detector 13 from the operation signal from the operation unit 22 when the operator operates the operation unit 22 to input the position of the detector 13.

  In FIG. 5, the display control unit 235 has shown an example in which the program name 32 of each part program is displayed as a text image. However, the present invention is not limited to this. For example, an icon image corresponding to each part program may be created, and the icon image may be displayed instead of the program name 32. Further, both the program name 32 and the icon image may be displayed.

In the embodiment described above, the example in which the program name 32 corresponding to the part program selected by the selection unit 232 is displayed on the display screen 31 is shown, but the present invention is not limited to this.
For example, the display control unit 235 may display all the part programs on the display screen 31 and may highlight the part program selected by the selection unit 232.
Further, the program name (or icon image) of the part program corresponding to the processing start position within the second distance range wider than the first distance range with the position of the detector 13 as the center is displayed on the display screen 31 and selected. The part program selected by the unit 232 may be highlighted.
In such a case, the part program corresponding to the position of the detector 13 is highlighted, so that an inconvenience that the operator designates an incorrect part program can be suppressed.

  Further, the part program displayed on the display screen 31 is not limited to the example of FIG. 5. For example, the part programs selected by the selection unit 232 may be displayed as a list in a table format. Even in this case, since only the part program corresponding to the position of the detector 13 is displayed, a desired part program can be easily found compared to the conventional case, and operability can be improved.

In the said embodiment, the structure which the detector 13 can move to the X direction which is a 1st direction, and the Z direction which is a 3rd direction was illustrated. On the other hand, for example, the angle of the stylus 133 of the detector 13 may be changed. In this case, the selection unit 232 selects the part program based on the angle of the stylus 133 in addition to the position of the detector 13. May be. Further, the display control unit 235 may display a screen in which the program name 32 is arranged along a virtual circle according to the angle of the stylus 133.
Furthermore, as a reference for selecting a part program, the weight of the workpiece W or the like may be used in addition to the position and angle of the detector 13 (operating unit). In this case, a weight measuring unit that measures the weight of the workpiece W placed on the table 12 is provided. Then, the reference weight of the workpiece W to be measured is also recorded in association with the part program stored in the storage unit 21, and the selection unit 232 narrows down the part program based on the position and angle of the detector 13. The part program corresponding to the reference weight that is the same as or substantially the same as the weight measured by the weight measuring unit is selected.

In the above-described embodiment, after the detector 13 is moved to the processing start position in step S1, the processing after step S2 is performed. In step S1, the display device 30 is moved as the detector 13 is moved. The part program (program name 32) displayed on the display screen 31 may be changed.
Further, as described above, after displaying all part programs or part programs within the second distance range from the position of the detector 13, the part program selected by the selection unit 232 may be highlighted. In this case, the highlighted part program changes as the detector 13 moves. Therefore, the operator can set the processing start position of the detector 13 while confirming the emphasized part program on the display screen 31. As a result, for example, even if the person knows the part program to be implemented and is unfamiliar with the installation position of the workpiece W or the position setting of the detector 13, the target part program is selected by the selection unit while viewing the display screen 31. As selected by H.232, the position of the workpiece W and the position of the detector 13 can be set.

  In the above embodiment, when it is determined as Yes in step S4 (when there is one part program selected by the selection unit 232), the process proceeds to step S7, and measurement processing is immediately performed by the operation control unit 234. However, the measurement process is not limited to this. For example, the measurement process may be performed only when designated by the operator through steps S5 to S6.
