[0002]
[Prior art]
Conventionally, a system for automatically measuring various workpieces having different shapes conveyed through a conveying line is known (for example, JP-A-60-35210). In this type of system, a workpiece is imaged by an imaging device arranged upstream of the line, the shape of the workpiece is discriminated from the imaging result, and a measuring robot arranged downstream of the line is operated by a program corresponding to the discriminated shape. I am doing so.
[0003]
When measuring the dimensions of a workpiece with a coordinate measuring machine as in this system, the probe used by the coordinate measuring machine, the movement path of the probe, and the like are given by a part program for controlling the coordinate measuring machine. Therefore, even if the workpiece has the same type of shape, if the dimensional values such as the position where the workpiece is placed and the inner diameter, outer diameter, and height are different, a part program corresponding to each position and dimensional value is created. , Have to be prepared.
[0004]
Therefore, the present applicant provides means for capturing each workpiece as an external information capturing means and recognizing the position, size, and shape of the workpiece, and external information such as position, size, shape, etc. from the external information capturing means is parametric. A measuring system has been proposed in which various workpieces with different positions and dimensional values can be measured with one type of part program by giving them as part program arguments (Japanese Patent Laid-Open No. Hei 8-14876).
[0005]
[Problems to be solved by the invention]
However, in a measurement system in which a plurality of in-line measuring machines are arranged along the transport line, if the above-described external information capturing means is provided in each in-line measuring machine, a similar database is created in the process of recognition processing in each in-line measuring machine. As a result of the reference, the databases are duplicated as a whole system, and when the database is changed, all of the databases of the inline measuring instruments must be changed, and there is a problem that it takes time to update the system. In addition, this kind of recognition processing may be necessary even for a machine tool provided in the transfer line, and in this case, the database overlaps between the machine tool and the inline measuring machine.
[0006]
The present invention has been made to solve such problems, and an object of the present invention is to provide an in-line measurement system that can reduce the waste of the system and save the trouble of updating the system.

[0018]
Next, the operation of the system configured as described above will be described.
FIG. 7 is a time chart showing the task execution state of the control supervision apparatus 5, and the horizontal axis is time. As shown in FIG. 7A, the control supervision apparatus 5 performs measurement processing in a multitask on a plurality of works flowing through the transfer line. For example, the execution of the measurement sequence A for the workpiece WA is started by the inline measuring machine 3a, and the measurement sequence B is started and the measurement of the workpiece WB is started before the measurement of the workpiece WA is completed. Further, as shown in FIG. 7B, when it is necessary to perform measurement with the measurement sequence X and the measurement sequence Y with respect to the same workpiece WA, the measurement sequence Z is added to the measurement sequence Z in the control control unit 5. By describing two instructions for executing X and measurement sequence Y, both measurements can be performed automatically and continuously. This is called a macro function. In addition, the abnormality monitoring task is always executed in parallel with these measurement sequences, and the abnormality of each part is constantly monitored.
[0019]
FIG. 8 is a flowchart of the abnormality monitoring task. Abnormal events from the transport device 1, the stage moving mechanisms 12, 23 and the measuring machines 11, 22 are detected (S110, S120, S130), and a stop command for transport, stage and measurement is output (S111, 121, 131). Then, abnormal data is input (S112, S122, S132) and displayed (S113, S123, S133). Repeat this. In order to perform self-diagnosis of the presence or absence of abnormality of the measuring machines 11 and 22, for example, a method of measuring a master work whose calibration value is known at regular time intervals and checking a change in the measured value can be considered. Here, only abnormal detection of each part is taken as an example, but when the actual conveyance device, coordinate measuring machine, etc. can output various information, such as the progress status of the part program currently being executed, in real time It is also possible to constantly monitor these information and display the contents thereof.
[0020]
FIG. 9 is a flowchart showing a procedure for executing a measurement sequence in the control control device 5. First, the operator designates the name and number of the measurement sequence from the input device (operation panel) 46 and starts a series of measurements. In the measurement sequence, measurement procedures (work types and order of measuring machines to be used) by the plurality of in-line measuring machines 3a and 3b are determined. The measurement sequence is input from the auxiliary storage device 48 in advance or stored in the individual work information database 57 using a keyboard or the like. When the measurement sequence is specified and execution is started (S1), the contents (commands) of the measurement sequence are sequentially fetched from the database 57 under the control of the sequence control unit 58 and interpreted by the measurement / control command decoding unit 53. Depending on the contents, a command is output to the transfer device 1 and the inline measuring machines 3a and 3b (S2). At this time, the actual transmission / reception of commands and data with the transport device 1 and the measuring machines 3a and 3b is performed by the external control device 44 in accordance with a communication process described later.
[0021]
If the transfer device 1 and the corresponding measuring device 3a or 3b are not in a stand-by state, the operation waits if the stop device is in a stop state. A work is carried into the corresponding measuring machine 3a or 3b from the storage location. When the carry-in is completed (S5), the control supervision apparatus 5 activates a measurement task to be described later (S6), and thereafter, the processing of this flow and the measurement task are performed as multitask processing. When the measurement task is completed (S7), a workpiece unloading command is output from the corresponding measuring device 3a or 3b (S8), and the workpiece is returned from the measuring device 3a or 3b to the work place in the transfer device 1. When the unloading is completed (S9), it is confirmed whether or not the measurement sequence is all completed (S10). When all the measurement sequence commands are executed, the process returns to the top and waits for an instruction to execute the next measurement sequence (S10). .
[0022]
Next, details of the measurement task will be described. FIG. 10 is a flowchart of the measurement task. When the control supervision apparatus 5 outputs an imaging command to the measuring machine 3a or 3b at the start of measurement, the work is placed on a pallet or the like and loaded into the imaging area, and the work is imaged for a certain period by the imaging supervision apparatus. The image data is input to 5 (S21). At this time, by applying illumination light to the work from an appropriate direction, clear image information in which the contrast between the work part and the background is emphasized as shown in FIG. 11 can be obtained. When the image data is supplied to the image processing unit 55, the image processing unit 55 calculates preliminary information from the supplied image data (S22). That is, as shown in FIG. 12, the image data is binarized by the binarizing unit 61, and then the edge portion of the binary image is extracted by the contour extracting unit 62. Subsequently, in order to increase the processing efficiency of pattern matching, the feature extraction unit 63 extracts a feature portion from the contour information, and the feature portion and some basic patterns stored in the basic pattern storage unit 64 are compared with each other in the matching unit 65. Is matched. Thereby, based on the obtained work pattern, the position calculation unit 66 and the main dimension calculation unit 67 calculate the main dimensions such as the position and inner diameter, the outer shape, the height, and the width of the work from the characteristic part of the image. Thus, preliminary information including the work pattern, the work position, and the main work dimensions is obtained (S22).
[0023]
Next, the work position in the image processing coordinate system obtained by the image processing unit 55 is converted into a work position in the coordinate measuring machine coordinate system by the coordinate system correction unit 56 (S23), and the converted work position and image processing are performed. The workpiece pattern and workpiece main dimensions given from the section 55 are stored in the workpiece individual information database 57 (S24). Subsequently, under the control of the sequence control unit 58, the data of the work pattern, the work position, and the work main dimensions are transmitted to the in-line measuring machine 3a or 3b, and a PP program selection command (S25), followed by a variable. A storage command (S26) to the register 35 is sequentially output. When the stage carry-in command (S27) is output, the stage moving mechanism 12 operates under the control of the controller 15 of the in-line measuring machine 3a, and the slide table is moved from the imaging area to the measurement area by a predetermined amount. The workpiece is moved to the measurement area.
[0024]
When the transfer of the workpiece is completed (S28), the measurement command is transferred (S29), the PP program execution unit 33 is activated, and the selected PP program is executed.
The PP program is given information such as the amount of movement of the probe and information for specifying the selected probe as variables, so that it can flexibly handle workpieces of various sizes. 13 and 14 are diagrams showing an example of the PP program. Here, V1, V2, V3,..., U9, U10, L9, etc. are variables, and the numerical values corresponding to these are given from the image processing unit 55 or obtained by calculation inside the PP program and stored in the variable register 35. Stored. In this example, the inner and outer diameters of the cylinder are measured. For example, V1 is the depth of the cylinder, V2 is the number of measurement points, V3 is the diameter, V20 is the number of cross sections to be measured, and U9 is the probe type.
[0025]
The PP program execution unit 33 refers to the contents of the variable register 35 at any time during the execution of the PP program, supplies the probe movement command and the necessary movement amount to the controller 15, and touches the CMM 11. The signal probe is moved according to the PP program. Thereby, automatic measurement is performed. Further, the PP program execution unit 33 obtains the position of the workpiece from the actual three-dimensional measurement value obtained in the measurement process, and replaces the previously given workpiece position with the workpiece position obtained from the actual measurement value. As a result, the subsequent measurement is executed based on the newly obtained accurate work position.
[0026]
When the measurement is completed (S30), a command is transmitted to transmit the measurement data from the inline measuring instrument 3a to the control control unit 5 (S31), and the measurement data is input via the serial bus 4 (S32). The measurement data is stored in the individual work information database 57 via the output unit 52, the measurement / control result decoding unit 54, and the sequence control unit 58 (S33). Then, a carry-out command of the stage moving mechanism 12 is output (S34), and the work is moved from the measurement area to the imaging area. When the unloading is completed, the measurement operation is terminated (S35).
[0027]
FIGS. 15 and 16 are flowcharts showing a procedure of processes to be executed by the external control device 17 of the inline measuring device 3a in the above process. First, since the command or event includes a command from the control control device 5 and an event from the coordinate measuring machine 11, it is confirmed from which the command or event is (S41), and a command from the control control device 5 is checked. In the case of, processing according to the contents of the command is executed. In this example, as commands, an imaging command (S42), a PP program selection command (S44), a variable register storage command (S46), a stage carry-in command (S48), a measurement command (S50), a measurement data transmission command (S52), and a stage There are export commands (S54). In response to these commands, output of image data to the serial bus 4 (S43), PP program selection command (S45), variable register storage command (S47), stage loading An instruction (S49), a measurement instruction (S51), a transmission of measurement data to the serial bus 4 (S53), and a stage carry-out instruction (S55) are executed.
[0028]
In the case of an event from the coordinate measuring machine 11 (S61), a stage loading completion event (S62), a measurement completion event (S64), a stage unloading completion event (S66), a stage abnormal event (S68), a measurement abnormal event ( S70) and the like, and for each of these events, information indicating the stage loading completion (S63), measurement completion (S65), stage unloading completion (S67), stage abnormality (S70), and measurement abnormality (S72), respectively. Output to the serial bus 4.
[0029]
It should be noted that the external control device 44 of the control control device 5 basically performs the same processing as this, and therefore details thereof are omitted.
According to this system, the control integrated device 5 comprehensively recognizes the work information of each inline measuring machine 3a, 3b, and returns the recognition result to each inline measuring machine 3a, 3b, thereby as an argument of the PP program. In addition, since it is used to select PP programs, there is no duplication of circuits for recognition processing of workpieces, databases used for recognition processing, etc., and it is easy to reduce system costs and cope with database changes The effect that it is.
[0030]
In the above embodiment, the in-line measuring instrument 3a is provided with the pattern-specific PP program database 31 and the PP program selection unit 32, but this is provided on the control control unit 5 side, and the selected PP program is transmitted via the communication means. May be transmitted to each in-line measuring machine.
[0031]
