  FIG. 1 is a diagram illustrating the configuration of a work training system 10 for painting work. The work training system 10 is for performing work training in product processing independently of the product processing line, and has a function of performing work training particularly according to the work procedure. The work training system 10 includes a training work 20 and a training machine 50, and the training machine 50 includes a training processing machine 52 equipped with a measuring device 60 and a training machine body 80. The training machine main body 80 and the training processing machine 52 are connected by a paint substitute air supply pipe 54 and a plurality of signal lines 56. The training machine main body 80 includes a control device 90, and the control device 90 includes a data processing unit 92, a storage unit 98, and a display unit 96.

  2 is a detailed view of the training work 20, FIG. 3 is a partially enlarged view of the training work 20, FIG. 4 is a detailed view of the training machine 50, and FIG. 5 is a training processing machine 52 equipped with the measuring device 60. FIG. 6 is a diagram for explaining the arrangement of each of the plurality of measuring devices 60 mounted on the training processing machine 52, FIG. 7 is a diagram for explaining the evaluation of the holding posture, and FIG. It is a figure explaining work training system 10 with a block diagram.

  The work 20 for training uses the workpiece | work raw material in which a series of painting work is actually implemented in a production line, and the content of the work procedure outline of the series of painting work was visually shown by the several mark on the surface. Is. In the training work 20, the material itself is flowed on an actual production line, but a plurality of marks are not attached on the actual production line. The plurality of marks are visual indicators attached so that work training can be easily performed according to a time sequence of work procedure procedures.

  A material 22 constituting the training work 20 is an object on which a painting operation is performed. For example, it is a metal plate for vehicles and has a three-dimensional outer shape according to product specifications as shown in FIG.

  A color-specific line 24 attached to the training work 20 indicates a processing locus necessary for processing accuracy in the painting work. The color-specific line 24 is a line indicating a trajectory for painting. The color-specific line 24 is a line for each color according to the requirements of the processing trajectory, for example, the distinction of the paint color and the distinction of the paint width. In the example of FIG. 2, three types of color-specific lines 25, 26, and 27 are shown. For example, the color-specific line 25 has a yellow line on the material 22, the color-specific line 26 has a white line on the material 22, and the color-specific line 27 has a blue line on the material 22. Attached.

  Thus, since the processing locus in the painting work is indicated by the line mark in accordance with the work procedure procedure, the contents of the work procedure procedure can be visually shown to the worker receiving training. The worker who receives the training can improve the proficiency level of the work according to the contents of the work procedure procedure by performing the painting training work along this line. In addition, when work requirements related to the machining trajectory are different, distinction is made according to the color of the line. For example, for the same color line, it is visually indicated that the machining trajectory should be applied with the same work requirement. It is. By repeating this, the proficiency level of performing a series of painting operations is improved while distinguishing different operation requirements.

  The work start point mark 28 attached to the training work 20 is a direction indication mark attached to the start point of the paint work when the paint direction is a work requirement in the work procedure. In the example of FIG. 2, a triangular dedicated mark is provided at the end of each color line. It is shown that the coating is performed toward the tip of the triangular mark. In the example of FIG. 2, at the right end portion of the material 22, two kinds of work start marks 29 and 30 visually indicate that the painting is performed while reciprocating the painting direction.

  The pitch mark 32 shown in the enlarged view of FIG. 3 is a mark that is attached to the color-specific line 26 of the training work 20 and visually indicates the processing speed according to the work procedure, that is, the coating speed. In order to distinguish between a case where coating is performed at a high coating speed and a case where coating is performed at a low coating speed to form the processing locus indicated by the color-specific line 26, the distance between adjacent pitch marks 32 is changed. To do. That is, when the coating speed is high, the distance between adjacent pitch marks 32 is shortened according to the speed, and when the speed is low, the distance between adjacent pitch marks 32 is increased according to the speed. Thus, the processing speed visually indicated in the work procedure can be visually indicated on the material 22.

  The work 20 for training is preferably divided into a plurality of blocks or zones in consideration of work training. As a result, it is expected that the proficiency level of the work training can be improved more quickly than when the work training is performed in one zone. In the example of FIG. 2, the discontinuity of the color-specific line 24 is a zone boundary, and in this example, the color line 24 is divided into at least four zones. And it is preferable to provide a plurality of color-specific lines 24 in each zone. As a result, work training can be performed in detail. Each color line 24 is preferably provided with a plurality of measurement points. It is preferable to provide measurement points at locations where evaluation requirements are indicated in the work procedure, and further increase the number of installation locations as necessary.

The training machine main body 80 is provided with a control device 90.

  The control device 90 includes a data processing unit 92, a display unit 96, and a storage unit 98. The storage unit 98 stores basic requirements and the like corresponding to elements in accordance with work procedure procedures. The data processing unit 92 has a function of collecting work performance information from a plurality of measurement devices 60 mounted on the training processing machine 52 and comparing the stored contents of the storage unit 98 with the evaluation of the training work. . The display unit 96 has a function of displaying the evaluation judgment of the training work according to a time series or the like and displaying it in real time to the worker receiving the training. Details of the control device 90 will be described later with reference to FIG.

  The training processing machine 52 performs processing on the training workpiece 20, and is a painting gun for spraying paint substitute air for training painting. In FIG. 5, using the training processing machine 52, the color-specific line 24 visually shown on the training work 20 is used as a work index, and the state where the paint substitute air is sprayed on the processing point 14 is shown. It is shown.

  As a plurality of measuring devices 60 mounted in association with the training machine 52, five measuring devices are used as shown by A, B, C, D, and E in FIG.

The speed measuring device 62 shown as A in FIG. 6 irradiates the plurality of pitch marks 32 described in FIG. 3 with light, measures the processing speed V of the training work based on the detection of the reflected light, and works skills. It is a diffuse reflection type measuring instrument having a function of outputting as work performance information of the processing speed V as an element. Specifically, the irradiation light passes through the pitch mark 32, the interval time t of the pulse signal generated by detecting the reflected light is measured, and p / t obtained by dividing the installation interval p of the pitch mark 32 by t. Thus, the processing speed V along the color-specific line 24 of the training processing machine 52 can be obtained.

  The distance measuring device 64 shown as B in FIG. 6 has a function of measuring the distance between the training workpiece 20 and the training processing machine 52 and outputting it as work performance information of the processing distance S that is a work skill element. It is a distance sensor. Specifically, an appropriate distance sensor is used, its analog output is processed, and the distance between the training workpiece 20 and the training processing machine 52 is simply measured based on the sensor use area and gain adjustment. I can do it.

  A flow rate measuring device 66 shown as C in FIG. 6 measures the flow rate of paint substitute air that is a working fluid, and outputs it as work performance information of the fluid usage amount Q that is a work skill element, that is, the use amount of paint substitute air. It is a flow sensor which has a function to do. Specifically, a flow sensor is installed in the path of the paint gun blow air and paint substitute air on the training machine 52, and its analog output is processed to handle the fluid usage based on the sensor usage area and gain adjustment. The flow rate to be measured can be simply measured.

  The trajectory measuring device 68 shown as D in FIG. 6 irradiates the color-specific lines 24 described in FIG. 2 with light, measures the processing trajectory of the training work based on the detection of the reflected light, and uses the work skill element. It is a regressive reflection type measuring instrument having a function of outputting it as work performance information of a certain machining trajectory T. Specifically, the color difference between the trajectory tape color, which is the color-specific line 24 pasted on the training work 20, and the material color of the material 22 is measured with a retro-reflective measuring instrument, and the training machine 52 feeds it. The trajectory of the operation can be simply measured. In FIG. 6, the feeding of the training processing machine 52 by the operator is indicated by a white arrow.

  An angle measuring device 70 shown as E in FIG. 6 is a work skill element that irradiates light to the training work 20 and measures the processing angle of the training work based on detection of the amount of reflected light from the processing point 14. This is a photoelectric sensor having a function of outputting as work result information of the processing angle θ. Specifically, the reflected light amount of the photoelectric sensor radiated toward the processing point 14 of the training work 20 is detected, and the inclination of the processing direction of the training processing machine 52 with respect to the training work 20 is determined from the decrease in the light amount due to the angle change. The angle can be simply measured.

  In FIG. 1 and FIG. 4, as work performance information from these measuring instruments, the processing speed is V, the processing distance is S, the fluid usage is Q, the processing trajectory is T, and the processing angle is θ. Is shown.

  As described above, the velocity measuring device 62, the trajectory measuring device 68, and the angle measuring device 70 among the plurality of measuring devices 60 each irradiate the work 20 for training with light. As shown in FIG. 6, these measuring instruments are attached to a training processing machine with an inclination angle to each other, whereby a plurality of irradiation light spots are provided on the training work 20. By detecting the relative positional relationship between the plurality of irradiation light spots, the holding posture by the operator of the training processing machine 52 can be obtained.

  That is, when a plurality of light irradiators are attached to the training processing machine 52 so as to be inclined with respect to each other, the position of the irradiation light spot on the training work 20 of the light irradiated from these is set to the posture of the training processing machine 52. Depending on the change, each moves in a different size. For example, when the standard holding posture of the training processing machine 52 in accordance with the procedure of the work procedure is set so that all irradiation light spots are gathered at the processing point 14 on the training workpiece 20, the standard holding posture is set. When the holding posture is deviated from the position, the positions of the plurality of irradiation light spots on the training work 20 are in the vicinity of the processing point 14 but are in a dispersed positional relationship.

  This is shown in FIGS. 7 (a) and 7 (b). These figures are diagrams schematically showing how the positions on the color-specific lines 24 change due to the change in the holding posture of the training processing machine 52 for the irradiation light spots from the three measuring devices. . FIG. 7A shows a state when the standard holding posture is instructed in the work procedure, and FIG. 7B shows a state when the holding posture is deviated from the standard holding posture.

  In FIG. 7A, all three irradiation light spots are gathered at a substantially central position in the width direction of the color-specific line 24, and the processing point 14 is also substantially circular. On the other hand, when the holding posture is deviated from the standard holding posture, the positions of the three irradiation light spots are deviated from the center position in the width direction of the color-specific lines 24 as shown in FIG. The processing point 14 is also an elliptical shape with a spread.

  As described above, the plurality of measuring devices that irradiate the measurement work 20 with the measurement light are attached to the training processing machine 52 with an inclination angle to each other. Based on the detection of the relative positional relationship of the points, the holding posture by the worker of the training processing machine 52 can be obtained and output as work performance information of the holding posture, which is a work skill element.

  FIG. 8 is a block diagram showing the relationship among the above elements of the work training system 10. In the block diagram, the work training system 10 can be represented by a training work 20, a training processing machine 52 on which the measuring device 60 is mounted, and a control device 90.

Specifically, in the above example, the processing speed V, the processing distance S, the fluid usage amount Q, the processing trajectory T, the processing angle θ, Each holding posture is used as a work skill element, and the requirements of the acceptable range in these work procedure procedures are shown. For example, if the upper limit of the pass range is 10 cm / s and the lower limit is 5 cm / s for the processing speed V at a certain processing point 14, the element correspondence requirement at the processing point 14 is 10 cm / s, the lower limit is 5 cm / s. As described above, the element correspondence basic requirement is given in association with the position of each processing point 14 and each work skill element in a series of operations in product processing.

  The data processing unit 92 of the control device 90 obtains the work procedure procedure registration module 114 that acquires the contents of the work procedure procedure from the input unit 94 and registers them in the storage unit 98, and the work performance information in the training work from the plurality of measuring devices 60.

The first stage is basic skill training in which the processing site is limited, and the second stage is element work training in which a series of work of product processing is comprehensively performed using the training work 20 and the training machine 50.

  Basic skill training is performed for the first time or for a worker who is not very familiar with the product processing for which work training is to be performed, and is intended to train basic processing skills for limited processing parts. is there. Here, an appropriate training preparation work is first performed (S10). Then, basic training regarding handling of the processing machine is performed (S12), and thereafter, element unit / processing site limited training is performed (S14). The element unit is to limit work skill elements assuming that there is a series of work in product processing. For example, as a work skill element, the work training can be limited to the processing speed or limited to the processing distance. The processing part limitation means that the training work 20 does not perform work training over the entire area but performs the work training limited to a part of the area. For example, when the work 20 for training is divided into a plurality of blocks or zones, the work training can be limited to the one zone. Or it is good also as what restrict | limits to the line 24 according to one color, and performs work training.

  As described above, the basic skill training is a work training in which the work skill elements and the processing parts are limited and can be, for example, a work training in which the same training work is repeated repeatedly. And the result of work training is compared with a target skill level, and it is determined whether it passes or fails (S16). If not, the process returns to S12 and the training work is repeated. If it passes, it moves to elemental work training related to a series of work. Of course, if necessary, basic skill training on other work skill elements and processing parts may be performed.

  Specifically, the training machine 50 is used to repeatedly perform the machining work as the work training with respect to the limited machining part of the work 20 for training, and the result is measured by the measuring device 60. Detect and compare with the basic requirements of the work procedure, that is, the evaluation requirements. For example, when the work skill element is limited to the machining speed, the measuring device 60 can compare the detection result of the speed measuring device 62 with its acceptable range to determine whether it is acceptable or not.

  FIG. 12 is a diagram showing this state. The horizontal axis in FIG. 2 indicates time, that is, the number of repetitions of work training, and the vertical axis indicates requirement values, that is, values of machining speeds in the above example. FIG. 12 shows a standard machining speed 130, an acceptable range 132 indicated by an upper limit machining speed and a lower limit machining speed, and a semi-acceptable range 134 as basic requirements of the machining speed for the machining part performed in the basic skill training. ing. The semi-acceptance range 134 is a provisional acceptance range that can be provided according to the stage of work training, for example.

  And the actual value 150 of the processing speed by the speed measuring device 62 is shown as the actual result of the training work. Here, in the initial stage of the work training, it is shown that the actual value that protrudes from the semi-acceptance range 134 gradually enters the acceptance range 132 and approaches the standard processing speed 130. As described above, the basic skill training is performed by repeatedly performing the work training on the same processing site for the same work skill element.

  Returning to FIG. 11 again, in order to perform element work training, first, appropriate training work preparation is performed (S20), and work procedure procedures are formulated (S22). If similar product processing has already been performed on the production line, the procedure of the work procedure can be used. In consideration of new product processing, when a production line is constructed, or when it is necessary to perform a training work before the production line is constructed, a work procedure procedure adapted to the new product processing is formulated.

  Then, the formulated work procedure is dropped into the training work 20 (S24). The drop-in means that the contents of the work procedure are visually displayed on the training work 20 by a plurality of marks. As described with reference to FIG. 2, in the work procedure, when the work skill element is a machining trajectory, the color-specific line 24 is displayed. When the work skill element is the machining speed, the pitch mark 32 is replaced with the training work 20. Appended on top. When the work skill element is a machining distance, a machining angle, etc., the measurement point for measuring the machining distance and the measurement point for measuring the machining angle are provided at the machining site where the evaluation requirements for the work skill element are specified. Are respectively added on the training work 20. As described above, the basic requirements indicated in the work procedure, that is, the measurement points and marks of the evaluation requirements, are sequentially added to the training work 20 in time series.

  Next, the work procedure procedure for the training machine 52 is registered (S26). This procedure is executed by the function of the work procedure procedure registration module 114 in the data processing unit 92 of the control device 90. Specifically, time-series evaluation requirements for work procedure procedures are input from the input unit 94 and acquired, and stored in the storage unit 98 as element correspondence basic requirements 100.

  When the preparation for the training work 20 and the training processing machine 52 in the work training system 10 is completed in this way, the training work 20 is attached to the training machine 50, and actual work training is performed. Here, the simulated work training using the work training system is performed by the worker who passed in S16 of the basic skill training (S28). In the simulated work training, a training work 20 with a visual mark different from a material in an actual production line is used, and a measuring device 60 is mounted on the training processing machine 52, and paint substitute air is used instead of paint. This is because it is different from the actual product processing work in that it is used.

  In this work training, work result data is recorded in parallel (S30). This procedure is executed by the function of the work record information acquisition module 116 in the data processing unit 92 of the control device 90. Specifically, work performance information is acquired via the measurement device 60 mounted on the training processing machine 52 and is once recorded in the storage unit 98.

  Then, evaluation / determination of the training work is performed (S32). This procedure is executed by the function of the evaluation determination module 118 in the data processing unit 92 of the control device 90. Specifically, the element correspondence basic requirement 100 stored in the storage unit 98 and the previous work record information are read and compared. The element correspondence basic requirement 100 is an evaluation requirement and is, for example, within a pass range. Therefore, the evaluation / determination can be performed based on whether or not the value of the work performance information is within the pass range.

  This compares with the target skill level. If the target skill level is not reached, the process returns to S28 as a failure, and the work training is repeated. When the target skill level has been reached, the work training can be ended (S36) as a pass.

  In the evaluation / determination in S32, the training worker can be notified of the result, and feedback of the work training can be performed. Specifically, the result of S32 is displayed on the display unit 96. This procedure is executed by the function of the display processing module 120 in the data processing unit 92 of the control device 90.

  Here, evaluation / determination is performed each time the measurement apparatus 60 passes the measurement points using a series of measurement points on the work 20 for training. The pass ranges at each measurement point are not necessarily the same. For example, if the work skill element is the processing speed and multiple measurement points are provided in time series, the pass range of the processing speed is high on one measurement point and the processing speed is pass on another measurement point. It is possible that the range is on the low speed side.

  Also, in some cases, each measurement point may not necessarily be for the same work skill element. For example, when arranged in chronological order, the measurement point that evaluates the machining speed is the next measurement point that evaluates the machining distance, and in some cases, the next measurement point is for the machining angle. obtain.

  FIG. 13 is a diagram showing this state. Here, the horizontal axis shows measurement points in a series of operations in time series, and the vertical axis shows requirement values. FIG. 13 shows a case where the measurement points for the same work skill element continue in time series, but the acceptable range varies in time series. Here, when the work skill element is a machining speed, the actual machining speed 151 that is the actual work information is shown in time series for each measurement point. Here, the standard machining speed 140 is different at each measurement point, and accordingly, the lower limit machining speed 142 and the upper limit machining speed 143 are also different at each measurement point.

  In this way, in a series of operations in product processing, the acceptance range at the measurement points arranged in time series may change, so this is shown to the operator who performs the operation training and the operation content is followed. There is a need. In the example of FIG. 13, the first part of the measurement point is the work result information that protrudes the pass range that is the evaluation requirement, but in the second half of the measurement point, the work content closely follows the evaluation requirement. Is shown.

  As described in FIG. 13, when the evaluation requirements change in time series, the evaluation / determination is performed by comparing the work performance information with the evaluation requirements every time the measurement points are passed. Various methods can be taken according to the contents of work.

  For example, when the work 20 for training is divided into a plurality of blocks or zones, the evaluation / determination can be performed for each zone. Further, when a plurality of lines are provided in the zone, evaluation / determination can be performed for each line.

  Also, when measurement points with different work skill elements are arranged in time series, the work performance information of different work skill elements and the pass range that is the evaluation requirement are evaluated and judged in order of time series, and this is displayed. it can. In that case, it is preferable to indicate the work performance information and the evaluation requirements as standardized values. Alternatively, even in such a case, the same work skill elements may be extracted in a time series, arranged, evaluated / determined, and displayed. For example, when the work skill element that is the target of the measurement point changes, such as machining speed, machining distance, machining angle, machining speed, machining speed, machining distance, machining angle, machining speed, etc., in time series, These may be normalized and displayed side by side as one time series requirement value. Alternatively, even in such a case, the processing speed may be extracted and displayed in time series. The processing distance and processing angle may be extracted separately and arranged in time series.

  Moreover, instead of using the evaluation requirements as the basic requirements of the work procedure procedure, it is also possible to use actual measurement data of skilled workers. Or it is good also as what sets the pass range according to the proficiency level of work training.
