  In a factory or the like, when a worker assembles a plurality of parts and manufactures a predetermined product, a work instruction diagram for instructing the worker to perform the assembly work is presented. The work instruction diagram usually shows a list of parts required for each assembly operation in accordance with a predetermined assembly sequence, and further shows an external view of a product being manufactured assembled in each operation, an external view of a finished product, etc. Is shown. Therefore, the operator can know which parts should be assembled in what order and how.

  Conventionally, work instruction diagrams have been created using paper as a medium, but in recent years, computerization of work instruction diagrams has progressed. For example, the work instruction diagram is stored in a database connected to a network, and is displayed on the display device of the terminal in response to a request from the worker. Also, the computerization of the work instruction diagram facilitates the introduction of photographic images and animations into the work instruction diagram, and the worker is provided with a more realistic work instruction diagram.

  For example, Cited Document 1 discloses an example of a work instruction diagram creating apparatus that creates a work instruction diagram using a photographic image, and Patent Document 2 displays a product assembly procedure using animation. Techniques to do this are disclosed.

As shown in FIG. 1, the work instruction diagram generation device 1 includes a work instruction diagram generation server 2, one or more work instruction diagram generation terminals 3 connected to the work instruction diagram generation server 2 via a network 4, It is comprised including.

  The work instruction diagram generation server 2 is configured by a general computer, and includes a server processing device 21 including a CPU (Central Processing Unit) and a storage device (not shown), and a work instruction diagram element DB stored in a hard disk device or the like. (Database) 22.

  The work instruction diagram generation terminal 3 is configured by a general computer, and includes a terminal processing device 31 including a CPU and a storage device (not shown), a work instruction diagram generation rule DB 32 stored in a hard disk device, a keyboard, An input device 33 including a mouse and a display device 34 including an LCD (Liquid Crystal Display) are included.

  The server processing device 21 receives a product name input via the input device 33 of the work instruction diagram generation terminal 3 and transmitted from the terminal processing device 31 via the network 4, and the product having the received product name. The process of creating the work instruction diagram is executed. Details of the processing will be described in detail with reference to FIG.

  The terminal processing device 31 is communicably connected to the server processing device 21 via the network 4, and executes dialogue processing with an operator necessary for executing the work instruction diagram generation processing in the server processing device 21. . That is, information necessary for work instruction diagram generation processing input from the input device 33 by the worker is input to the server processing device 21 via the terminal processing device 31. In addition, information on the processing result output by the work instruction diagram generation processing is displayed on the display device 34 via the terminal processing device 31.

  In the present embodiment, it is assumed that a product 3D model DB management server (not shown) is further connected to the work instruction diagram generation apparatus 1 via the network 4. The product three-dimensional model DB management server holds and manages a product three-dimensional model DB in which three-dimensional model information about products manufactured in the factory and parts used in the products is registered. Here, the three-dimensional model information of each product includes data such as three-dimensional shape data and mounting positions of units and parts constituting the product.

  The work instruction diagram element DB 22 of the work instruction diagram generation server 2 stores data necessary for the server processing device 21 to create and display a work instruction diagram of a product when a certain product is designated. At this time, the data includes the 3D model information of the product acquired from the product 3D model DB, and further includes data generated by the server processing device 21 based on the 3D model information of the product. It is. Details of the data constituting the work instruction diagram element DB 22 will be described later.

  In addition, the work instruction diagram generation rule DB 32 of the work instruction diagram generation terminal 3 holds rules for assembling a product that the server processing device 21 needs when creating a product work instruction diagram. Details of the rule will be described later, but the content of the rule usually depends on the type of product to be assembled. For this reason, the rule is often determined empirically by the person in charge of the product, and here, the work instruction diagram generation rule DB 32 is included in the work instruction diagram generation terminal 3.

  Therefore, the work instruction diagram generation rule DB 32 may be included on the server processing device 21 side and may be a part of the work instruction diagram element DB 22. In such a case, the input device 33 and the display device 34 may be directly connected to the server processing device 21 so that the server processing device 21 executes processing to be executed by the terminal processing device 31. Good.

  Next, with reference to FIGS. 2 to 11 in addition to FIG. 1, the work instruction diagram generation process performed in the work instruction diagram generation apparatus 1 will be described in detail. Here, FIG. 2 is a diagram showing an example of the processing flow of work instruction diagram generation processing in the server processing device 21, and FIGS. 3 and 4 show examples of the configuration of data held in the work instruction diagram element DB 22. FIG. 5 is a diagram showing an example of the configuration of data held in the work instruction diagram generation rule DB 32. In FIG. 2, broken lines with arrows indicate information reference relationships.

<1. 3D model information acquisition processing>
When the server processing device 21 of the work instruction diagram generation server 2 receives the login information input by the worker via the input device 33 of the work instruction diagram generation terminal 3, the server processing device 21 executes the work instruction diagram generation processing shown in FIG. Start. First, the server processing device 21 executes a 3D model information acquisition process (step S11).

  In the 3D model information acquisition process, the server processing device 21 accepts an input such as the name of a product that is a work instruction diagram generation target, and uses the name from the product 3D model DB management server (not shown in FIG. 1). The unit information 221, the three-dimensional model information 222, the component adjacent information 225, the electrical component information 232, the mechanical component information 233, and the like regarding the specified product are acquired, and the acquired information is stored in the work instruction diagram element DB 22.

  Here, the unit information 221 (see FIG. 3A) includes model names, unit coordinates (arrangement position coordinates), unit names, etc., for the units (semi-finished products or pre-assembled products including a plurality of parts) constituting the product. It consists of data. The three-dimensional model information 222 (see FIG. 3B) includes data such as a model name, shape, mass, volume, department, attachment coordinates, hierarchy, attachment surface, and the like. It represents the physical shape and mounting position of the part. The component adjacent information 225 (see FIG. 3F) is composed of a parent model name and a child model name, and represents the correspondence between the parent component and the child component specified by the model name.

  The electrical component information 232 (see FIG. 4E) is composed of data such as model name, component name, model, rating, logical coordinates, device, socket model, mounting screw, component code, department, etc. It consists of data for identifying the electrical component, and data such as mounting position and mounting component. The logical coordinates are data representing the connection relationship when electrical components are connected to each other, and the device is data representing the type of electrical component (integrated circuit, diode, switch, terminal, etc.). The machine part information 233 (see FIG. 4F) is composed of data such as a model name, a figure number, a history, a part name, a part number, a material, a quantity, and a note, and the detailed specifications of the machine part can be understood. Has been.

  The server processing device 21 does not need to perform the 3D model information acquisition process (step S11) every time, and data including the 3D model information 222 of the product has already been stored in the work instruction diagram element DB 22. In the case where the error occurs, the process of step S11 can be omitted. In addition, after the server processing apparatus 21 has previously acquired data including the 3D model information 222, if some of the data has been updated in the original product 3D model DB, the updated 3D Data including the model information 222 is acquired again.

<2. Subpart processing>
Next, the server processing device 21 executes a child component forming process for collecting a three-dimensional model that does not need to be assembled as one component (see step S12 in FIG. 2). For example, with respect to parts that have been assembled or purchased in the previous stage of the process of giving work instructions, the component parts can be handled as child parts.

  In this child component conversion processing, unit information 221, three-dimensional model information 222, and child component conversion rules 321 (see FIG. 5A) are referred to when the processing is executed. As a result of the processing, child component information 223 is obtained. Created. Here, the child part information 223 (see FIG. 3D) includes data of the child part name and the model name, and the model name of the child part belonging to the same unit or the same part and the child parts are included. The child part names indicating that they belong to the same unit or the same part are associated with each other.

  Further, the sub-partification rule 321 defines a rule for extracting a part or unit to be sub-parts. For example, when the rule is a department AAA, the department is determined from the 3D model information 222 as AAA. Model names are extracted, and the same child part names are associated with these model names. This example of the sub-part rule is effective when, for example, a certain purchased item and the components constituting the purchased item are registered in the three-dimensional model information 222 and all the departments are AAA.

  In addition, a model name can be registered in the child component rule 321. In that case, the server processing apparatus 21 can create the child component information 223 by referring to the component adjacent information 225 and extracting the child model name having the model name as the parent model name.

<3. Block processing>
Next, the server processing device 21 executes a blocking process for generating a block in which components that can be integrated as the same single structural body among the components constituting the product are generated (see step S13 in FIG. 2). In this blocking process, the server processing device 21 refers to the 3D model information 222, the child component information 223, the component adjacent information 225, the fastening component information 226, the process information 227, and the like of the work instruction diagram element DB 22, and the work instruction Block information 224 is created based on the blocking rules 322 of the diagram generation rule DB 32. The block information 224 (see FIG. 3E) is configured to include block name and model name data, and is information that associates the model name of a unit or part that has been blocked with a block name that identifies the block. It is.

  The blocking rule 322 (see FIG. 5B) defines a rule for extracting parts and units to be collected as one block. For example, when the rule is a department BBB, a three-dimensional model is set. A model name whose department is BBB is extracted from the information 222, and a certain block name is associated with the model name. A model name can also be registered in the blocking rule 322. In this case, the server processing device 21 can create the block information 224 by extracting the child model name having the model name as the parent model name with reference to the component adjacent information 225.

  Further, when the blocking rule 322 includes rules such as “same mounting surface” and “fastening material and parts to be fastened”, the server processing device 21 sets the mounting coordinates, hierarchy, and mounting of the 3D model information 222. Block parts belonging to the same mounting surface, block fastening material with parts to be fastened, block adjacent parts, etc. based on data such as surface, and data such as part adjacency information 225 and fastening part information 226 It can be made.

  The block generated in this way can be regarded as one large part and should be called a blocked part. Further, the block is handled as a structure to be assembled in the product assembly operation. Therefore, the block can be said to be a collection of parts to be displayed on the same page in the work instruction diagram.

<4. Child parts / block editing process>
Next, the server processing device 21 receives the operator's input operation and executes a child part / block editing process for editing the child part information 223 and the block information 224 (see step S14 in FIG. 2). The child part / block editing process will be described in detail below with reference to FIG. Here, FIG. 6 is a diagram showing an example of a child part / block editing screen displayed on the display device 34 of the work instruction diagram generation terminal 3 in the child part / block editing process.

  6 is displayed on the display device 34 by the terminal processing device 31 in accordance with an instruction from the server processing device 21 via the network 4, the description is complicated. In order to avoid this, hereinafter, in this specification, the server processing device 21 is described as being directly displayed on the display device 34. Similarly, data input from the input device 33 is described as being directly received by the server processing device 21.

  As shown in FIG. 6, the child part / block edit screen 60 includes a “highlight” button 61, a “hide” button 62, a “work order edit” button 63, a pre-change hierarchy information display area 64, and a post-change hierarchy. An information display area 65, a 3D model display area 66, and the like are displayed.

  Here, in the hierarchy information display area 64 before change, the hierarchy information of the units and parts before the child parts processing and the blocking process are executed is displayed, and in the hierarchy information display area 65 after the change, child parts are displayed. The hierarchical information of the units and parts after the processing and blocking processing are executed is displayed. In FIG. 6, a portion surrounded by a solid circle indicates an example of a block, and a portion surrounded by a broken circle indicates an example of a child part. In the three-dimensional model display area 66, an external view of the product for which the work instruction diagram is generated is displayed according to the three-dimensional model. At this time, the three-dimensional model display can be changed to a wire display that displays only the edge of the component, a translucent display that transmits the model, or the like.

  In the child part / block editing screen 60, one or more of the model name, block name, and child part name displayed in the pre-change hierarchy information display area 64 and the post-change hierarchy information display area 65 are selected. When the “highlight” button 61 is clicked, the selected model name, block name, and child part name are highlighted and displayed in the 3D model of the product displayed in the 3D model display area 66. The parts corresponding to the selected model name, block name, and child part name are highlighted.

  Conversely, when a certain part is selected in the three-dimensional model of the product displayed in the three-dimensional model display area 66 and the “highlight” button 61 is clicked, the selected part is highlighted. In addition to the light display, the model name, block name, and child component name corresponding to the selected portion are highlighted in the pre-change hierarchy information display area 64 and post-change hierarchy information display area 65.

  Also, one or more model names, block names or child part names displayed in the pre-change hierarchy information display area 64 or post-change hierarchy information display area 65 are selected, and the “Hide” button 62 is clicked. Then, the display of the selected model name, block name, and child part name is deleted from the hierarchical display, and the selected three-dimensional model of the product displayed in the three-dimensional model display area 66 is selected. The display of the part corresponding to the model name, block name, and child part name is deleted.

  Conversely, when a certain part is selected in the three-dimensional model of the product displayed in the three-dimensional model display area 66 and the “Hide” button 62 is clicked, the selected part is displayed. Is deleted, and the display of the model name, block name, and child part name corresponding to the selected portion is deleted from the hierarchical display in the hierarchical information display area 64 before change and the hierarchical information display area 65 after change.

  With the “highlight” and “non-display” functions as described above, the worker visually confirms which part of the three-dimensional model of the product corresponds to the part to be made into a child part or block. It becomes possible. Therefore, it becomes easy for the operator to determine whether or not the subparts or blocks are appropriate for assembling the product. Therefore, when the operator determines that improper blocking is performed, the model name, block name, and child part name displayed in the hierarchy information display area 65 after change are appropriately displayed as appropriate. By changing, the configuration of the block can be corrected.

  In that case, the worker selects a model name of a model inappropriate to belong to a certain block in a hierarchical display such as a block displayed in the post-change hierarchical information display area 65 with, for example, a mouse cursor, Simply drag and drop to the appropriate block name.

  As described above, in the child part / block editing process, the child part information 223 and the block information 224 created by the server processing device 21 in the child part process and the blocking process can be changed by the operator's operation.

  Although not shown in FIG. 6, the child part / block editing screen 60 displays the number and ratio of the models that are blocked for each block, and the presence and number of parts that are not blocked. May be displayed. In this case, the operator can know at a glance which parts are not blocked by highlighting all the blocked blocks.

<5. Work order generation processing>
Thus, when the editing of the child parts and blocks by the worker is completed and the “work order editing” button 63 on the child part / block editing screen 60 is clicked, the server processing device 21 executes work order generation processing ( (Refer FIG. 2, step S15). In this work order generation process, the server processing device 21 refers to data such as the process information 227, the three-dimensional model information 222, the block information 224, and the component adjacent information 225 in the work instruction diagram element DB 22, and the work instruction diagram generation rule DB 32 The work order is determined based on the mounting surface work order rule 323 and the individual component work order rule 324, and the result is stored in the work order / camera position information 229.

  The process information 227 (see FIG. 3 (h)) is information including a process name, an order, an allocation model name, an attachment surface, and the like, and indicating an order in which processes are performed. Here, the model name of the allocation model name may be a block name. Also, the mounting surface means, for example, the right side, left side, ceiling, floor, etc. of the product, and is information that categorizes the parts mounting location. In the completed three-dimensional model of the product, all of its components are It belongs to one of the mounting surfaces.

  The mounting surface work order rule 323 (see FIG. 5C) is information that defines a rule for assigning the mounting surface work order. The mounting surface work order refers to a work order determined for each mounting surface so as to improve work efficiency so that the movement distance of the worker is reduced. For example, when it is necessary to move from a work at a height of 2 m or more to a floor work and a side work, the work efficiency decreases as the number of movements between the mounting faces increases. Therefore, the mounting surface work order is defined according to the mounting surface work order rule that works for each mounting surface, and the work efficiency is improved.

  The individual part work order rule 324 (see FIG. 5D) is information that defines a rule for assigning the order of attaching the parts belonging to the attachment surface in each attachment surface. The order is an order in which the work efficiency of the worker and the work efficiency at the time of maintenance are considered in advance. For example, the order of individual component work such as from top to bottom and from left to right is determined.

  The work order / camera position information 229 (see FIG. 4B) includes data such as a block name, work order, coordinates, and orientation. In the work order generation process, the work order is generated for the assembly work of the parts included in the block specified by the block name. The coordinate and orientation data mean the camera position and orientation, and are added in the next camera position information addition process.

  The mounting surface work order described above is a concept positioned higher than the individual parts work order. In addition, the order of the process information 227 is a concept that is positioned higher than the mounting surface work order. Therefore, it can be said that such work order and process order correspond to hierarchical information of parts to be assembled, that is, blocks. In other words, by configuring a block for each type of part and instructing assembly for each block, not only can the work efficiency be improved, but also the utilization efficiency of devices and tools used for the assembly can be improved. .

  Here, it supplements about the effect of making components into blocks in relation to the work order and the process order. FIG. 7 is a diagram illustrating an example of an external view of a product that is a work instruction diagram generation target viewed from the upper right. As shown in FIG. 7, the product has a structure in which a pillar C, a pillar D, a pillar E, and a pillar F are provided on a pedestal A, and a ceiling B is provided thereon. In such a product, it is not possible to change the work order of mounting the base A first and mounting the ceiling B last. On the other hand, the order of attaching the pillar C, the pillar D, the pillar E, and the pillar F to the pedestal A can be freely changed.

  An operator can determine at a glance whether or not the work order can be changed in a product having a simple structure as shown in FIG. However, since the actual product structure is more complicated, in general, the operator can easily determine whether or not the work order can be changed only by looking at the three-dimensional model of the product displayed on the display device 34. It is not always possible.

  However, if a plurality of parts are combined into one by block processing, the structure of the product is simplified, so that the operator can easily determine whether the work order of the plurality of blocks can be changed. Is possible. Incidentally, in the example of FIG. 7, the column C, the column D, the column E, and the column F are configured by a number of different parts, and the shapes thereof are different from each other. It becomes difficult to understand whether or not to replace. On the other hand, if it can be seen at a glance that each of the pillar C, the pillar D, the pillar E, and the pillar F is composed of one block, it is possible to easily determine whether the mounting order can be changed. .

<6. Camera position information addition processing>
Next, camera position information addition processing is executed (see step S16 in FIG. 2). That is, the server processing device 21 performs each work based on the work order / camera position information 229, work drawing camera position information 228, and work drawing camera position rule 325 in which the work order determined in the work order generation process is stored. The camera position for displaying the work drawing to be used is determined, and the data (coordinates, orientation, etc.) of the determined camera position is stored in the work order / camera position information 229.

  Here, the work drawing camera position information 228 (see FIG. 4A) is composed of data such as a pattern name, coordinates, orientation, and mounting surface, is identified by the pattern name, and is previously determined according to the mounting surface and the like. The set camera position data (coordinates, orientation, etc.). In this embodiment, the camera position is referred to as a camera position. However, when actually displaying a three-dimensional model of a product, the camera is not used, and the camera position in this embodiment is actually a server. This means the viewpoint position when the processing device 21 displays a 3D model.

  The work drawing camera position rule 325 is composed of data such as conditions for applying the rule, camera position (coordinates), and orientation. If the parts constituting the block match the condition data, the work position camera position rule 325 is set to the camera position of the block. Coordinate and orientation data are applied.

  The camera position data referred to in the work drawing camera position information 228 and the work drawing camera position rule 325 may include display magnification and camera tilt data in addition to the coordinate and orientation data.

<7. Work order editing process>
Next, the server processing device 21 receives the operator's input operation and executes a work order editing process for editing the work order data of the work order / camera position information 229 (see step S17 in FIG. 2). This work order editing process will be described in detail below with reference to FIG. Here, FIG. 8 is a diagram showing an example of a work order editing screen displayed on the display device 34 of the work instruction diagram generation terminal 3 when executing the work order editing process.

  As shown in FIG. 8, the work order editing screen 80 includes a “camera position” button 81, an “animation playback” button 82, a “work instruction diagram output” button 83, a “hide” button 84, and a work order display area 85. A three-dimensional model display area 86 is displayed. At this time, the work order display area 85 displays the block names to be worked in the ascending order of the work order of the work order / camera position information 229. In the three-dimensional model display area 86, a three-dimensional model of the product for which the work instruction diagram is generated is displayed.

  The operator can freely change the work order by selecting the block name displayed in the work order display area 85 with a mouse cursor or the like and dragging the selected block name in the vertical direction. Also, if the selected block name is dragged and dropped to another block name, the selected block can be made a lower-level block included in the block to which the block is dropped.

  Further, when a block name is selected in the work order display area 85, the selected block name is highlighted, and correspondingly, in the 3D model display area 86, the selected block name is displayed. The 3D model part of the specified block is highlighted. Similarly, when a certain part is selected in the three-dimensional model of the product displayed in the three-dimensional model display area 86, the block name of the block corresponding to the selected part is highlighted in the work order display area 85. Is displayed.

  Further, when a block name is selected in the work order display area 85 and the “Hide” button 84 is clicked, the display of the block name of the selected block name is erased, and the 3D model display area In 86, the 3D model portion of the block specified by the block name is deleted from the display of the 3D model. Similarly, when a certain part is selected in the 3D model of the product displayed in the 3D model display area 86 and the “Hide” button 84 is clicked, the selected part is displayed in the work order display area 85. The block name of the block corresponding to is deleted from the display.

  In the above “non-display” process, the object may not be erased but may be displayed thinly or translucently. This makes it easier for the operator to see that there are blocks that are hidden.

<8. Camera position editing process>
Thus, when the editing of the work order by the worker is completed and the “camera position” button 81 on the work order editing screen 80 is clicked, the server processing device 21 accepts the operator's input operation, and the work order / camera A camera position editing process for editing data such as the camera position (coordinates) and orientation of the position information 229 is executed (see step S18 in FIG. 2). This camera position editing process will be described in detail below with reference to FIG. Here, FIG. 9 is a diagram showing an example of the camera position editing screen displayed on the display device 34 of the work instruction diagram generation terminal 3 when executing the camera position editing process.

  As shown in FIG. 9, the camera position editing screen 90 includes a shared pattern selection window 91, an individual pattern selection window 92, a pattern name input window 93, a current camera position data display window 94, an adjusting camera position data display window 95, A “pattern deletion” button 96, a “pattern registration” button 97, a “view acquisition” button 98, a “camera position registration” button 99, a “return” button 101, a 3D model display area 100, and the like are displayed.

  At this time, in the current camera position data display window 94, the assembly of the block (specified by the block name) already determined in the camera position information addition process (step S16) and stored in the work order / camera position information 229 is performed. Camera position data (coordinates, orientation, etc.) associated with the work is displayed. In the 3D model display area 100, a 3D model of the product for the work of the block is displayed based on the camera position.

  The operator can freely rotate the displayed three-dimensional model in the three-dimensional space by mouse operation or the like, and can enlarge or reduce the model. At this time, the camera position data corresponding to the three-dimensional model being displayed in the three-dimensional model display area 100 is displayed in the adjusting camera position data display window 95. That is, when the server processing device 21 receives an operation input for rotating, enlarging, or reducing the 3D model, the server processing device 21 updates the display of the 3D model in accordance with the operation, and the camera position data (coordinates, orientation, etc.). And the calculation result is displayed on the camera position data display window 95 during adjustment.

  Therefore, when the worker views the 3D model displayed in the 3D model display area 100 and determines that the camera position is at an appropriate position or angle for the assembly work of the block, the worker The “camera position registration” button 99 is clicked to determine the camera position for the assembly work of the block.

  At this time, the server processing device 21 calculates camera position data (coordinates, orientation, etc.) based on the 3D model being displayed in the 3D model display area 100, and the calculated camera position data (coordinates, orientation, etc.). Thus, the camera position data (coordinates, orientation, etc.) of the work order / camera position information 229 associated with the work (block name) is updated.

  In the camera position editing screen 90, the shared pattern selection window 91 displays the pattern name registered in the work drawing camera position information 228, and the personal pattern selection window 92 is set by the operator for personal use. The pattern name for selecting the selected camera position data is displayed. It is assumed that the camera position data set for personal use by the worker is stored in, for example, a storage device (hereinafter referred to as personal storage file) attached to the terminal processing device 31.

  In this case, the operator can select one of these pattern names with a mouse cursor or the like. At this time, the server processing device 21 extracts the camera position data (coordinates, orientation, etc.) corresponding to the selected pattern name from the work drawing camera position information 228 or the camera position data set for personal use. The extracted camera position data is displayed on the current camera position data display window 94.

  Next, when the operator clicks the “view acquisition” button 98, the 3D model of the product corresponding to the camera position data currently displayed in the camera position data display window 94 is displayed in the 3D model display area 100. Thereafter, as described above, the worker can freely rotate the displayed three-dimensional model in the three-dimensional space by using a mouse or the like, and can enlarge or reduce the model.

  Next, when the operator clicks the “camera position registration” button 99, the camera position for the assembly work of the block is determined. That is, the server processing device 21 updates the display of the current camera position data display window 94 with the camera position data currently displayed in the camera position data display window 95 under adjustment, and also updates the display in the work order / camera position information 229. The camera position data (coordinates, orientation, etc.) associated with the block name is updated.

  The operator selects one of the pattern names displayed in the shared pattern selection window 91 and the personal pattern selection window 92, clicks the “view acquisition” button 98, and then enters the 3D model display area 100. It is also possible to click the “camera position registration” button 99 without performing any operation on the displayed three-dimensional model. In this case, it can be said that the worker reuses the camera position data registered in the work drawing camera position information 228 or the personal storage file as it is as the camera position data of the assembly work of the block.

  In addition, the operator performs an operation such as rotation on the 3D model displayed in the 3D model display area 100, sets a new pattern name in the pattern name input window 93, You can also click the "" button. In this case, the server processing device 21 uses the camera position data currently displayed in the camera position data display window 95 under adjustment as the camera position data of the new pattern name as the camera position data 228 or the operator's Register in a personal storage file.

  Further, when the operator selects one or more pattern names from among the pattern names displayed in the shared pattern selection window 91 or the personal pattern selection window 92 and clicks the “delete pattern” button 96, the server The processing device 21 deletes the camera position data corresponding to the selected pattern name from the work drawing camera position information 228 or the personal storage file.

  The camera position editing process described above is performed for each work (block name) corresponding to all the works (that is, block names) defined in the work order / camera position information 229. Therefore, in order to clarify the target work (target block) of the camera position editing process, the block name is displayed in the 3D model display area 100 or the like.

  When the operator finishes the camera position editing operation using the camera position editing screen 90, the operator clicks a “return” button 101. In that case, the server processing device 21 closes the display of the camera position editing screen 90 and displays the work order editing screen 80 displayed previously again.

  Since the camera position data such as coordinates and orientations in the work order / camera position information 229 has already been set in the camera position information addition process (step S16), the server processing device 21 is partly or entirely. The execution of the camera position editing process for the work (block) may be omitted.

<9. Animation order, camera position confirmation process>
Next, when the “reproduce animation” button 82 is clicked on the work order editing screen 80, the server processing device 21 executes the work order and camera position confirmation process in the animation (see FIG. 2, step S19). That is, the server processing device 21 follows the work order of the assembly of the block stored in the work order / camera position information 229, and the three-dimensional model of the product reproduced based on the camera position data associated with the work of the block. Are sequentially displayed in the three-dimensional model display area 86 at predetermined time intervals. This display is nothing but an animation display in which each block is sequentially assembled and the product is assembled over time.

  It should be noted that the playback speed of the animation display can be changed as appropriate using a speed setting slider button (not shown). When a block name in a predetermined range is selected from the block names displayed in the work order display area 85 and the “reproduce animation” button 82 is clicked, only the animation of the assembly work of the block specified in that range is displayed. Displayed. Also, an “animation stop” button (not shown) may be provided, and when the “animation stop” button is clicked during animation display, the animation display may be stopped.

  With the animation display described above, the worker can see how the product is assembled, so that it is possible to easily determine whether the camera position is appropriate for each operation.

  Therefore, when the worker sees the animation display as described above and confirms that the camera position of each work is appropriate, that is, when the server processing device 21 accepts an operation input of “confirmation OK”. (Yes in step S20), the process proceeds to the next step S21. Further, when the worker views the animation display and determines that it is better to change the camera position for at least one work, that is, when the server processing device 21 receives an operation input other than “confirmation OK” (in step S20). No), returning to step S18, the camera position editing process (step S18) is executed again to change the camera position data.

  Here, the operation input of “confirmation OK” is to accept a click input of the “work instruction diagram output” button 83 on the work order editing screen 80, and the operation input that is not “confirmation OK” is “camera It is to accept the click input of the “position” button 81.

<10. Work instruction diagram output processing>
Therefore, when the “work instruction diagram output” button 83 is clicked on the work order editing screen 80, the server processing device 21 first executes a work instruction diagram template selection process (see FIG. 2, step S21).

  That is, the server processing device 21 displays a list of template names in the work instruction diagram format on the display device 34 with reference to the work instruction diagram format information 230 (see FIG. 4C) (not shown). Then, when the operator performs an operation of selecting one from the list of template names with a mouse cursor or the like, the server processing device 21 refers to the work instruction diagram format information 230 and refers to the file corresponding to the selected template name. A template for a work instruction diagram having a name is acquired.

  Next, the server processing device 21 creates a work instruction diagram for each work (block) using the acquired work instruction diagram template, and executes a work instruction diagram output process for output (see step S22). At this time, the 3D model of the product displayed in the work diagram display area 112 of the work instruction diagram is a 3D model obtained by the work order in animation and the camera position determined by the camera position process (step S19). FIG.

  10 and 11 are diagrams showing examples of work instruction diagrams according to the embodiment of the present invention, and FIG. 10 is a work presented when a work for mounting a block B1 representing a pillar on a pedestal is performed. An example of an instruction diagram, FIG. 11 is an example of a work instruction diagram presented when an operation of attaching a block T1 representing a ceiling on four pillars is performed. As shown in FIGS. 10 and 11, in the work instruction diagram 110, the process name column 111 displays process names of processes for assembling the respective blocks. For the process name, the process name corresponding to the block name can be obtained by referring to the block information 224 and the process information 227.

  In the diagram of the three-dimensional model of the product displayed in the work diagram display area 112, the block to be assembled in the process is highlighted and displayed. Therefore, the operator can visually recognize which block should be assembled in which position and how.

  Further, in the lower column part 114 of the work instruction diagram 110, various information about the parts necessary for the process is displayed. These pieces of information are information specified by the work instruction diagram template obtained from the work instruction diagram format information 230. The unit information 221, the fastening part information 226, the process information 227, the electrical part information 232, the machine part information 233, It is obtained by referring to the child component information 223, the block information 224, and the like.

  Further, in the note column 113 of the work instruction diagram 110, items that should be noted by the assembly worker during work are displayed. This annotation is input by the operator who generates the work instruction diagram via the input device 33 such as a keyboard.

<How to use created work instruction diagram>
The work instruction diagram generation procedure described with reference to FIGS. 2 to 11 is for creating a completely new work instruction diagram. Next, a procedure for creating a work instruction diagram when data related to the created work instruction diagram exists will be described with reference to FIG.

  FIG. 12 is a diagram illustrating an example of a correspondence relationship between two products having similar block hierarchical configurations and block departments. As shown in FIG. 12 (a), even if the individual block names are different between the existing product A and the new product B, the hierarchical structure of the blocks is the same, and further shown in FIG. 12 (b). Thus, if the departments associated with each block are the same between the product A and the product B, it can be said that the product A and the product B are very similar products. Here, the department is the department that manufactured the corresponding unit or part as described above (in the case of in-house production) or the manufacturer (in the case of a purchased product). In such a case, when viewed from the product A, the product B may be a part of a part that has been updated or a product that has a similar shape.

  In such a case, the work process and work instruction diagram of the product A can be applied to the product B. In this case, the unit of the product B, the adjacent relationship, the fastening part, the mechanical part, the electrical part, etc. , It is necessary to correspond to the unit, the adjacent relationship, the fastening part, the mechanical part, the electric part, etc. of the product A, respectively. The server processing device 21 uses the unit information 221, the fastening part information 226, the part adjacent information 225, the machine part information 233, the electrical part information 232, and the like to perform the association process.

  By performing such association, the server processing device 21 replaces the child part information 223, the block information 224, and the work order / camera position information 229 of the product A with the corresponding units and parts of the product B. Only the work order / camera position information 229 of the product B can be created.

  Thereafter, the worker who creates the work instruction diagram displays an animation or the like displayed based on the work order / camera position information 229 of the product B in accordance with the processing of step S19 to step S22 of FIG. As a result, the work order and the camera position are confirmed, and if the confirmation is OK, a work template may be selected as appropriate and a work instruction diagram may be output to the display device 34.

  As described above, if there is an existing product that has a work instruction diagram generated with a similar hierarchical structure and department of the product block, the existing product is made into child parts, blocked, work order, camera position, etc. By taking over the data, it is possible to reduce the labor of the worker who creates the work instruction diagram.

  As described above, according to the present embodiment, the server processing apparatus automatically converts the relationship between units and parts into subparts and blocks them based on the unit or part 3D model information 222, part adjacency information 225, and the like. Since the work order is generated and work drawings for each work are created, the burden on the worker who creates the work instruction diagram is greatly reduced.
