The shelf 12 functions as a parts warehouse. The shelf 12 is provided with a plurality of component mounting portions 21 on which components are mounted. In the examples shown in FIGS. 3 to 6, there are a total of 24 components, 4 steps in the vertical direction and 6 rows in the horizontal direction. The component mounting portion 21 of the above is provided. The plurality of component mounting portions 21 are configured as, for example, trays, and adjacent trays are separated by a side wall of each tray. Further, the shelf 12 is provided with a plurality of partition plates 22. Each partition plate 22 is arranged in a substantially vertical direction, and separates individual component mounting portions 21. As shown in FIG. 5, the partition plate 22 is arranged so that the tip of the partition plate 22 projects forward from the front surface of the shelf 12. On the other hand, the partition plate 22 may be arranged so that the rear end projects rearward from the rear surface of the shelf 12. A tray is mounted on each component mounting section 21, and a single type of component (for example, screws, brackets, rollers, etc.) is stored in the tray. An assembly tool such as an electric screwdriver may be mounted on the component mounting portion 21.

The opening 51 (51A to 51D) in front of each component mounting portion 21 shown in FIG. 5 is hereinafter also referred to as a sampling port 51. For example, the assembly worker puts his / her hand into the component mounting section 21 from the sampling port 51 and collects the components mounted on the component mounting section 21. The sampling port 51 is typically a space whose upper part is separated by a second plate-shaped member 34 and whose lower part is separated by a component mounting portion 21.

As shown in FIG. 5, each component mounting portion 21 is provided so as to be inclined so that the front portion is lowered from the rear portion. The space below the lowermost component mounting portion 21 is a dead space that is difficult to access from the front portion of the shelf 12, and as shown in FIGS. 3 and 4, the control device 11 is arranged in that space. There is. This makes it possible to efficiently utilize the space in the shelf 12. Further, a plurality of trays may be mounted on the component mounting portion 21. As a result, the production navigation system 10 can remove the empty front tray and place a new tray placed behind the empty tray at a position near the front surface of the shelf 12.

As shown in FIG. 6, each component mounting portion 21 can be distinguished by two letters of the alphabet added after the reference numeral “21”. The first character of the alphabet indicates a stage in which the component mounting portion 21 is arranged (from top to bottom, the first stage is a, the second stage is b, the third stage is c, and the fourth stage is d). The second letter of the alphabet is the row in which the component mounting unit 21 is arranged (from left to right, the first row is a, the second row is b, the third row is c, the fourth row is d, and the fifth row is e. , The sixth column shows f). For example, the component mounting section 21 in the first row from the top and the second row from the right is the component mounting section 21ab.

(Workbench 13)
The workbench 13 is a table used by assembly workers for parts assembly and the like. The workbench 13 has a flat table surface (upper surface). The pedestal surface is arranged so as to extend in the horizontal direction over the entire width of the shelf 12. The workbench 13 can also function as a projectable region in which the projected image projected from the projector 31 is imaged. In the example shown in FIG. 6, the workbench 13 has an assembly video display area 37, which is an area in which a moving image (assembly movie) of an assembly sample is displayed, and a caution display area, which is an area in which a warning is displayed. There are 38 and a work instruction display area 39, which is an area where work instructions are displayed. However, the assembly moving image display area 37, the caution display area 38, and the work instruction manual display area 39 may exist in a place different from the workbench 13.

(Imaging unit 14)
The image pickup unit 14 takes an image of the worker and outputs the captured image including the worker to the control device 11. The image pickup unit 14 may be, for example, a USB (Universal Serial Bus) camera. The imaging unit 14 corresponds to the sensor unit 130 described with reference to FIG.

The image pickup unit 14 takes an image of a worker (assembly worker). The image pickup unit 14 is provided with a support frame 44 that supports the mirror 32 at a position above the head height of a worker of standard height (for example, a position above the uppermost component mounting unit 21). Moreover, it is arranged at a position in front of the front surface of the shelf 12. As a result, it is possible to capture an captured image including an assembly worker located in front of the production navigation system 10. Here, the imaging unit 14 is arranged so that the imaging direction is directed toward the shelf 12, and the sampling ports 51 of all the component mounting units 21 provided on the shelf 12 are included in the imaging range. As a result, the captured image of the front surface of the shelf 12 including the hand that the assembly worker puts into the part mounting portion 21 from the collection port 51 in order to collect the parts or to return the once collected parts is obtained. It can be imaged.

(Display mechanism 15)
The display mechanism 15 is a mechanism for displaying various information to the operator. The display mechanism 15 corresponds to the display unit 120 described with reference to FIG. In the present embodiment, the display mechanism 15 includes a projector 31, a mirror 32, a first plate-shaped member 33, and a second plate-shaped member 34. The display mechanism 15 projects information (specifically, a projected image) onto the first plate-shaped member 33 and the second plate-shaped member 34 by using a so-called projection mapping technique.

・ Projector 31
As shown in FIGS. 3 and 4, the projector 31 is arranged on the shelf 12. The projector 31 irradiates the projected light toward the mirror 32. The projected light emitted from the projector 31 is reflected by the mirror 32 and reaches the first plate-shaped member 33 and the second plate-shaped member 34. That is, the projector 31 projects information on the first plate-shaped member 33 and the second plate-shaped member 34 via the mirror 32. The mirror 32 may also project information on other areas such as the top surface of the workbench 13 or the floor surface. The projector 31 is not limited to the top of the shelf 12, but the projected light directly reaches other regions such as the first plate-shaped member 33, the second plate-shaped member 34, the upper surface of the workbench 13 or the floor surface. It may be arranged at an angular position (ceiling or wall (not shown)). In that case, a plurality of projectors 31 may be arranged, and the projector that directly projects the projected light onto the first plate-shaped member 33 and the second plate-shaped member 34, the upper surface or the floor surface of the work table 13, and the like. It may be arranged separately from the projector that directly projects the projected light onto the area of.

・ Mirror 32
As shown in FIG. 4, the mirror 32 is provided by the support frame 44 at a position above the head height of a worker of standard height (for example, above the uppermost component mounting portion 21). Moreover, it is arranged at a position in front of the front surface of the shelf 12. Specifically, the mirror 32 is arranged above the workbench 13 and diagonally upward of the shelf 12 so that the reflecting surface faces the projector 31 and the first plate-shaped member 33. Then, as shown in FIG. 4, the mirror 32 reflects the projected light emitted from the projector 31 toward the first plate-shaped member 33 and the second plate-shaped member 34.

The mirror 32 is rotatably supported by a support mechanism so that the reflection angle can be changed in the vertical direction, and can be fixedly installed at an arbitrary reflection angle.

-First plate-shaped member 33
The first plate-shaped member 33 functions as a projectable region on which the projected image projected from the projector 31 is formed. The first plate-shaped member 33 extends in the left-right direction (horizontal direction) over the entire width of the shelf 12, and the length in the vertical direction (vertical direction) is longer than that of the second plate-shaped member 34. .. Therefore, the first plate-shaped member 33 is suitable for presenting information that requires a relatively large area. In the example shown in FIG. 6, the worker ID display area 35, which is an area in which the worker's identification information (worker ID) is displayed, and the product to be assembled by the assembly worker are on the first plate-shaped member 33. There is a product number display area 36, which is an area in which the identification information (product number) of the above is displayed. However, the worker ID display area 35 and the product number display area 36 may exist in a place different from that of the first plate-shaped member 33. The first plate-shaped member 33 is arranged at one or both positions above and below the component mounting portion 21. Preferably, the first plate-shaped member 33 is arranged above the component mounting portion 21 (that is, the uppermost stage of the shelf 12). As a result, the projected light is not blocked by the operator's hand regardless of which component mounting portion 21 is touched by the operator, so that the visibility of the projected information is always maintained high. It becomes possible.

-Second plate-shaped member 34
The second plate-shaped member 34 also functions as a projectable region in which the projected image projected from the projector 31 is imaged. The second plate-shaped member 34 extends in the left-right direction (horizontal direction) over the entire width of the shelf 12, and the length in the vertical direction (vertical direction) is shorter than that of the first plate-shaped member 33. .. The second plate-shaped member 34 is suitable for presenting information that requires only a relatively small area. As an example of such information, instruction information for instructing the collection of parts (collection instruction information described later) can be mentioned. For example, in the second plate-shaped member 34, the collection instruction information is projected on the area near the component mounting portion 21 on which the operator should collect the component. As a result, the operator can easily recognize the component mounting portion 21 from which the component should be collected. The second plate-shaped member 34 is arranged at one or both positions above and below each component mounting portion 21. Preferably, it is desirable that the second plate-shaped member 34 is arranged above each component mounting portion 21. As a result, when the operator puts his / her hand on the component mounting unit 21 according to the collection instruction information, the projected light of the instruction information is not blocked by the operator's hand, so that the visibility of the instruction information is maintained. It becomes possible.

As shown in FIG. 6, when the shelf 12 is viewed from the front, the second plate-shaped member 34 is arranged below the component mounting portions 21 in the first to third stages from the top. On the other hand, the second plate-shaped member 34 is not arranged below the component mounting portion 21 at the fourth stage from the top.

-Inclination of the first plate-shaped member 33 and the second plate-shaped member 34 As shown in FIG. 5, the first plate-shaped member 33 and the second plate-shaped member 34 are inclined obliquely to the front surface of the shelf 12. And are placed. In particular, the first plate-shaped member 33 and the second plate-shaped member 34 are arranged so as to be inclined so that the lower end is located forward of the upper end. And the inclination is stronger (that is, closer to horizontal) as it is placed downward. As a result, the angle between the first plate-shaped member 33 and the second plate-shaped member 34 and the projected light can be made closer to the vertical, and the projection with better visibility becomes possible.

(Code input unit 19)
The code input unit 19 reads the information code. The code input unit 19 corresponds to the input unit 140 described with reference to FIG. For example, the code input unit 19 is configured as a scanner and reads various information codes such as a bar code or a two-dimensional code. The code input unit 19 is not limited to the scanner, and may be composed of various input devices such as an IC card reader or a keyboard.

(Motion capture camera 20)
The motion capture camera 20 captures the state of the operator. The motion capture camera 20 corresponds to the sensor unit 130 described above with reference to FIG. The motion capture camera 20 captures almost the entire image of the operator, including at least the upper body of the operator. The motion capture camera 20 is arranged, for example, on the side of the shelf 12. The control device 11 can analyze the flow line of the operator, the direction of the face, and the like based on the moving image captured by the motion capture camera 20.

<< 2. Technical features >>
<2.1. Assembling work navigation ＞
The control device 11 performs navigation to support the assembly work by the worker (assembly worker), particularly the collection work of collecting parts from the shelf 12 for assembly. This point will be described in detail below. The shelf 12 corresponds to an example of an area (work area) in which work is performed by an operator. Therefore, the work area does not have to be the shelf 12, and may be a unit of an area where the work is performed by the worker. For example, when the parts are placed on a table, the work area may be a table on which the parts are placed.

Here, when a worker assembles a product having a certain product number "1234", the work is first performed on the shelf 12 corresponding to the production navigation system 10-1, and then on the shelf 12 corresponding to the production navigation system 10-2. It is mainly assumed that the next work is normal.

(1) Information acquisition In the control device 11, the acquisition unit 161 acquires the product number and the worker ID. Here, as an example, the product number and the worker ID are attached to documents such as a work plan as information codes, and are read from the code input unit 19 of the production navigation system 10-1 corresponding to the shelf on which the work should be performed first. It is assumed that the case is possible. In this case, the collecting worker holds the information code attached to the work plan over the code input unit 19 to read the information code attached to the work plan before starting the collecting work on the shelf on which the work should be performed first. Navigation (the following (3) display of collection instruction information) is started by reading the product number.

On the other hand, in the production navigation system 10-2 corresponding to the second and subsequent shelves, the communication unit 110 starts with the product number and the work from the production navigation system 10-1 corresponding to the shelf on which the work should be performed immediately before. Receive the person ID. Then, upon receiving the product number, navigation is started. The product number transmitted and received between the production navigation systems may correspond to an example of information indicating that the work has been completed (work completion information).

Then, the acquisition unit 161 acquires the scheduled work information, the front and rear work shelf information, and the guidance information corresponding to the product number. Here, it is assumed that the scheduled work information, the front and rear work shelf information, and the guidance information are associated with the product numbers and stored in advance by the storage unit 150 of the production navigation system 10. Then, it is assumed that the acquisition unit 161 acquires the scheduled work information, the front and rear work shelf information, and the guidance information corresponding to the product numbers by the storage unit 150. However, as another example, the scheduled work information, the front and rear work shelf information, and the guidance information may be stored in advance by the server 90 in association with the product number. In such a case, the acquisition unit 161 may acquire the scheduled work information, the front / rear work shelf information, and the guidance information corresponding to the product numbers from the server 90 via the communication unit 110.

Scheduled work information indicates a product assembly plan using the parts placed on the shelves 12. Here, the scheduled work information acquired by the acquisition unit 161 is the scheduled work information on the shelf 12 corresponding to the production navigation system 10. More specifically, in the production navigation system 10-1, the acquisition unit 161 acquires the scheduled work information on the shelf 12 corresponding to the production navigation system 10-1, and in the production navigation system 10-2, the acquisition unit 161 acquires the scheduled work information. , Acquires scheduled work information on the shelf 12 corresponding to the production navigation system 10-2.

FIG. 7 is a diagram showing examples of product numbers, scheduled work information, and guidance information. As shown in FIG. 7, the scheduled work information includes the order, rows, columns, and required quantity. The above-mentioned collection instruction information 61 is configured according to the order, rows, columns, and required quantity. The order is information indicating the collection order of parts. Rows and columns are part placement units 21 at the collection destination for each of the one or more parts that the assembler should collect for assembling the product. For example, the component mounting section 21 having 1 row and 2 columns corresponds to the component mounting section 21 in the first row from the top and the second column from the right, and corresponds to the component mounting section 21ab (FIG. 6). .. The required quantity is information indicating the number to be collected for each of one or more parts to be collected by the assembly worker for assembling the product.

Further, as shown in FIG. 7, the guidance information is associated with each order (each work) of the scheduled work information, and the assembly video file name (assembly video), the instruction file name (work instruction), and so on. And alerts. These guidance information is displayed corresponding to each work, as will be described later.

Here, it is mainly assumed that the scheduled work information and the guidance information shown in FIG. 7 are acquired by the acquisition unit 161 of the production navigation system 10-1. However, the format of the scheduled work information and the guidance information acquired by the acquisition unit 161 of the production navigation system 10-2 is the same as the format of the scheduled work information and the guidance information acquired by the acquisition unit 161 of the production navigation system 10-1. It may be.

The front and rear work shelf information indicates a shelf on which work should be performed immediately before the work on the shelf 12 and a shelf on which work should be performed next to the work on the shelf 12.

FIG. 8 is a diagram showing an example of front and rear work shelf information acquired by the control device 11 of the production navigation system 10-1. As shown in FIG. 8, the front and rear work shelf information acquired by the acquisition unit 161 of the production navigation system 10-1 includes information indicating the shelf on which the work should be performed immediately before (immediate work shelf), and the next work. It has information (next work shelf) indicating the shelf to be performed. Here, since there is no shelf on which the work should be performed before the work on the shelf 12 corresponding to the production navigation system 10-1, "-(none)" is set for the immediately preceding work shelf. Further, since the shelf to which the work should be performed next to the work on the shelf 12 corresponding to the production navigation system 10-2 is the shelf corresponding to the production navigation system 10-2, the next work shelf is "002 (production). (Shelves corresponding to the navigation system 10-2) ”is set.

FIG. 9 is a diagram showing an example of front and rear work shelf information acquired by the control device 11 of the production navigation system 10-2. As shown in FIG. 9, the front and rear work shelf information acquired by the acquisition unit 161 of the production navigation system 10-2 includes the immediately preceding work shelf and the next work shelf. Here, since the shelf to which the work should be performed before the work on the shelf 12 corresponding to the production navigation system 10-2 is the shelf corresponding to the production navigation system 10-1, the immediately preceding work shelf is "001 ( (Shelves corresponding to the production navigation system 10-1) ”is set. Further, since there is no shelf on which the work should be performed next to the work on the shelf 12 corresponding to the production navigation system 10-2, "-(none)" is set for the next work shelf.

(2) Guidance display before the start of work As described above, when the worker assembles the product, the work on the shelf 12 corresponding to the production navigation system 10-1 is performed first, and the work corresponds to the production navigation system 10-2. It is normal to work on the shelf 12 next. Therefore, when the worker first tries to start the work from the production navigation system 10-1 corresponding to the shelf on which the work should be performed first, the navigation is normally started.

On the other hand, if the worker mistakenly tries to start the work from the production navigation system 10-2 corresponding to the shelf on which the work should be performed first, move to the shelf on which the work should be performed first. Information to encourage is displayed. This allows the operator to recognize that the first shelf to work on is wrong and the shelf to work on immediately before.

More specifically, when the product number is read by the code input unit 19 and acquired by the acquisition unit 161 in the determination unit 163, the shelf corresponding to the code input unit 19 that has read the product number first performs the work. Determine if it is a shelf to do. As an example, in the determination unit 163, the shelf corresponding to the code input unit 19 that has read the product number first performs the work depending on whether or not "-(none)" is set in the work shelf immediately before the front and rear work shelf information. You may decide whether or not it is a shelf to do. The product number read by the code input unit 19 may correspond to an example of information indicating the start of work (work start information).

When the determination unit 163 determines that the shelf corresponding to the code input unit 19 that has read the product number is the shelf on which the work should be performed first, the presentation control unit 165 performs navigation. On the other hand, when the determination unit 163 determines that the shelf corresponding to the code input unit 19 that has read the product number is not the shelf on which the work should be performed first, the presentation control unit 165 should perform the work first. The display unit 120 is controlled so that information for prompting the movement to the shelf and the shelf on which the work should be performed immediately before (identification information of the shelf on which the work should be performed immediately before) are displayed.

As an example, in the production navigation system 10-1, when the product number is read by the code input unit 19 and acquired by the acquisition unit 161, the determination unit 163 is the work shelf immediately before the front and rear work shelf information (FIG. 8). Since "-(none)" is set in, it may be determined that the shelf corresponding to the production navigation system 10-1 is the shelf on which the work should be performed first. Then, the presentation control unit 165 may perform navigation.

On the other hand, in the production navigation system 10-2, when the product number is read by the code input unit 19 and acquired by the acquisition unit 161, the determination unit 163 is placed on the work shelf immediately before the front / rear work shelf information (FIG. 9). Since "001 (shelf corresponding to the production navigation system 10-1)" is set, it may be determined that the shelf corresponding to the production navigation system 10-2 is not the shelf on which the work should be performed first. Then, the presentation control unit 165 displays the information for prompting the movement to the shelf on which the work should be performed first, and the immediately preceding work shelf "001 (the shelf corresponding to the production navigation system 10-1)". The display unit 120 may be controlled.

FIG. 10 is a diagram showing an example of guidance information before the start of work. As shown in FIG. 10, the guidance information before starting the work is "Please move to the shelf where the work should be performed first. Work on the shelf 001 (the shelf corresponding to the production navigation system 10-1) is performed first. It may be a message such as "Please." As shown in FIG. 10, the guidance information before the start of work may be typically displayed in the warning display area 38 of the workbench 13 corresponding to the production navigation system 10-2. However, the place where the guidance information before the start of work is displayed is not limited.

(3) Display of Collection Instruction Information The control device 11 (for example, the presentation control unit 165) collects parts by an assembler from a shelf 12 provided with a plurality of parts mounting units 21 on which parts are placed. The display mechanism 15 is controlled so as to generate collection instruction information instructing work and display the generated collection instruction information. The control device 11 generates collection instruction information according to the scheduled work information. The collection instruction information is displayed on the first plate-shaped member 33 and / or the second plate-shaped member 34. The collection instruction information is information for instructing the collection of uncollected parts among one or more parts to be collected for assembling the planned product in the scheduled work information.

-Information indicating the component mounting unit 21 from which the component should be collected The collection instruction information includes information indicating the component mounting section 21 from which the component should be collected. By displaying such information, the sampling operator can recognize from which component mounting unit 21 the component should be sampled. Then, the collection instruction information is displayed in the area associated with the component mounting unit 21 on which the component should be collected. As a result, information indicating the component mounting section 21 from which the component should be collected is displayed in the area associated with the component mounting section 21, so that it is possible to determine from which component mounting section 21 the component should be sampled. It can be easily recognized. A display example of the collection indication information will be specifically described with reference to FIG.

FIG. 11 is a diagram for explaining an example of displaying the collection instruction information according to the present embodiment. FIG. 11 shows an example of displaying the collection instruction information when the production navigation system 10 is viewed from the front. In FIG. 11, the collection instruction information 61 is displayed as an arrow. The collection instruction information 61 indicates the component mounting section 21ab at the tip of the arrow as the component mounting section 21 on which the component should be sampled. Then, the collection instruction information 61 is displayed on the second plate-shaped member 34 directly above the component mounting portion 21ab as an area associated with the component mounting portion 21ab on which the component should be collected. By displaying the collection instruction information 61 in the vicinity of the component mounting portion 21ab in this way, the sampling operator can easily recognize that the component should be sampled from the component mounting portion 21ab. Become.

In addition to the arrows, the information indicating the component mounting unit 21 from which the components should be collected may be displayed as text, moving images, or images.

-Identification information of parts to be collected The collection instruction information may include identification information of parts to be collected. The component identification information here is, for example, the name of the component, the image of the component, the illustration of the component, or the like. This prevents mistakes in the parts to be collected. Further, when the collection instruction information includes the identification information of the parts to be collected, the collection instruction information regarding a plurality of parts may be projected at once.

-Information indicating the number of parts to be collected The collection instruction information may include information indicating the number of parts to be collected. The number of parts to be collected may be the total number of parts to be collected, or is the remaining number of parts to be collected obtained by subtracting the number of already collected parts from the total number of parts to be collected. You may. In any case, the collecting operator can easily recognize the number of parts to be collected.

-Other information Further, the presentation control unit 165 controls the display unit 120 so that information other than the collection instruction information is also displayed. For example, as shown in FIG. 6, the presentation control unit 165 displays an assembly moving image of an assembly sample in the assembly moving image display area 37, displays a warning in the warning display area 38, and displays a work instruction. It may be displayed in the work instruction display area 39. Further, the presentation control unit 165 may display the worker ID read by the code input unit 19 or the worker ID received by the communication unit 110 in the worker ID display area 35. Further, the presentation control unit 165 may display the product number read by the code input unit 19 or the product number received by the communication unit 110 in the product number display area 36.

-Supplement The presentation control unit 165 displays the collection instruction information regarding the part to be collected next when the determination unit 163 determines that the collection work instructed in the collection instruction information has been completed by the determination of the work status described later. The display unit 120 is controlled so as to be performed. The presentation control unit 165 displays the collection instruction information while switching the target parts until the collection of all the parts planned to be collected in the scheduled work information is completed.

(4) Judgment of work status The control device 11 (for example, the determination unit 163) determines the status of the collection work by the worker based on the captured image including the worker captured by the image pickup unit 14. Hereinafter, the determination target will be described in detail.

-Determining the content of the sampling work The control device 11 determines whether or not the sampling worker has touched the component mounting unit 21. For example, in the control device 11, when the region where the difference occurs between the captured image captured before the start of the work and the captured image captured during the work is the region corresponding to the collection port 51. It is determined that the sampling worker has put his / her hand on the component mounting unit 21.

When the control device 11 determines that the collecting worker has put his / her hand on the component mounting unit 21, the control device 11 identifies the part placing unit 21 that the collecting worker has put his / her hand on. For example, the control device 11 is modified by the sampling operator by determining which region of the component mounting portion 21 corresponds to the sampling port 51 in which the difference occurs between the captured images. The component mounting portion 21 is specified.

The control device 11 identifies the number of parts to be collected from the component mounting unit 21 by the collection operator in one collection operation. For example, the control device 11 identifies the number of parts collected from the component mounting unit 21 by recognizing from the captured image the number of times the collecting worker puts his / her hand in the component mounting unit 21 and puts it out. ..

-Determining the Correctness of the Collection Work The control device 11 determines whether or not the collection work indicated by the collection instruction information has been performed by the collection worker based on the determination result of the content of the collection work described above. The same work as the collection work indicated by the collection instruction information is also referred to as a correct collection work below. The collection work that is different from the collection work indicated by the collection instruction information is also referred to as an erroneous collection work below.

The control device 11 determines whether the sampling operation is correct or incorrect with respect to the parts collected by the sampling operator. In this case, the correct sampling operation is to sample the parts from the component mounting unit 21 specified as the sampling destination in the sampling instruction information. On the other hand, the erroneous sampling operation is to sample the parts from the component mounting section 21 different from the component mounting section 21 specified as the sampling destination in the sampling instruction information.

-Understanding the progress of the sampling work The control device 11 determines the number of parts mounted for each component mounting unit 21 based on the determination result of the content of the sampling work described above, each time a component is sampled. Subtract and add each time a part is returned. Such a calculation is performed for each component having the same identification information. As a result, the control device 11 can always grasp which component is mounted on which component mounting unit 21 and how many.

The control device 11 (for example, the determination unit 163) determines whether or not the collection operation instructed in the collection instruction information has been completed. For example, the control device 11 determines that all the parts planned to be collected in the scheduled work information are completed when the correct collection work is performed, and determines that the parts are not completed otherwise.

(5) Display of warning information The control device 11 (for example, the presentation control unit 165) controls the display mechanism 15 to display warning information when it is determined that an erroneous collection operation is performed by a collection operator. .. As a result, the collection worker can easily recognize that the erroneous collection work has been performed, the erroneous collection work can be repeated, and the erroneous collection of parts can be prevented. An example of the warning information will be described with reference to FIG.

FIG. 12 is a diagram for explaining an example of displaying warning information according to the present embodiment. FIG. 12 shows an example of displaying warning information when the production navigation system 10 is viewed from the front. As shown in FIG. 12, warning information 62 is displayed together with collection instruction information 61. The warning information 62 is displayed over all of the second plate-shaped members 34 in the fourth stage. As a result, the visibility of the warning information 62 is ensured. Here, the warning information 62 is displayed in a form different from that of the collection instruction information 61. As an example, the collection instruction information 61 is displayed in green, and the warning information 62 is displayed in red. As another example, the collection instruction information 61 may remain lit and the warning information 62 may blink. This also ensures the visibility of the warning information 62. Although FIG. 12 shows an example in which the collection instruction information 61 and the warning information 62 are displayed at the same time, the display of the collection instruction information 61 may be interrupted and only the warning information 62 may be displayed.

The warning information may include information indicating a component mounting unit 21 in which a component has been sampled in an erroneous sampling operation. As a result, the sampling operator can easily recognize to which component mounting unit 21 the component should be returned when attempting to return the component that has been erroneously sampled. This point will be described in detail with reference to FIG.

FIG. 13 is a diagram for explaining an example of displaying warning information according to the present embodiment. FIG. 13 shows an example of displaying warning information when the production navigation system 10 is viewed from the front. As shown in FIG. 13, warning information 62 is displayed together with collection instruction information 61. Here, as an example, it is assumed that the parts have been collected from the part mounting unit 21bc even though the collection instruction information 61 has been instructed to collect the parts from the component mounting unit 21ab. Therefore, the warning information 62 shown in FIG. 13 includes erroneous position information 63 indicating the component mounting portion 21bc from which the component was sampled in the erroneous sampling operation. The erroneous position information 63 is displayed on the second plate-shaped member 34 directly above the component mounting portion 21bc as an area associated with the component mounting portion 21 bc from which the component was sampled in the erroneous sampling operation. In this way, the error position information 63 is displayed in the vicinity of the component mounting section 21bc, so that the collecting operator mistakenly picked up the component from the component mounting section 21bc, and the component mounting section 21bc. It becomes possible to easily recognize that such a part should be returned.

The warning information may be displayed as text, moving image, or an image. In addition, the warning information may include arbitrary information in addition to the information described above.

As an example, the warning information may include identification information of parts collected in an erroneous collection operation. The component identification information here is, for example, the name of the component, the image of the component, the illustration of the component, or the like. This prevents mistakes in returning parts when attempting to return parts that have been erroneously collected.

The control device 11 controls the display mechanism 15 so as to stop the display of the warning information when the parts collected in the erroneous collection operation are returned to the component mounting unit 21. For example, in the example shown in FIG. 13, when a component erroneously collected is returned to the component mounting unit 21bc, the control device 11 stops displaying the warning information 62. It should be noted that whether or not the erroneously collected parts are correctly returned is whether or not the operation of the collecting operator putting his / her hand into the component mounting unit 21 where the erroneously collected parts is taken out is recognized from the captured image. May be determined by. As a result, the collecting operator can easily recognize that the parts collected by mistake have been returned without being mistaken.

(6) Guidance Display after Completion of Work As described above, the control device 11 (for example, the determination unit 163) determines whether or not the collection work instructed in the collection instruction information has been completed.

More specifically, the determination unit 163 includes scheduled work information (FIG. 7) indicating the work scheduled to be performed by the worker on the shelf 12 corresponding to the production navigation system 10 and the worker each time the correct sampling work is performed. It is determined whether or not the actual work information indicating the work performed on the shelf 12 matches with the actual work information. As a result, the determination unit 163 determines whether or not the collection work has been completed.

When the work schedule information and the actual work information match, the presentation control unit 165 registers the information that the worker plans to perform the work on another shelf following the work indicated by the scheduled work information. If so, the display unit 120 is controlled so that the information for prompting the movement to the other shelf (hereinafter, also referred to as “guidance information after the work is completed”) is displayed. This makes it possible for an operator to easily understand that he / she should move between work areas when he / she should move between work areas.

As an example, in the production navigation system 10-1, the work is carried out as shown in the “row”, “column”, and “required quantity” of the scheduled work information (FIG. 7) acquired by the acquisition unit 161 in the order 1 to 4. It is assumed that the determination is made by the determination unit 163. At this time, since "002 (a shelf corresponding to the production navigation system 10-2)" is set in the next work shelf of the front and rear work shelf information (FIG. 8), the presentation control unit 165 is set to the production navigation system 10-2. The display unit 120 may be controlled so that information (guidance information after the work is completed) for prompting the movement to the corresponding shelf is displayed. Then, the communication control unit 167 may control the communication unit 110 so that the product number and the worker ID are transmitted to the production navigation system 10-2. As described above, the product number transmitted and received between the production navigation systems may correspond to an example of work completion information.

FIG. 14 is a diagram showing an example of guidance information after the work is completed. As shown in FIG. 14, the guidance information after the work is completed may be a message such as "Please perform the work on the shelf 002 (the shelf corresponding to the production navigation system 10-2) next" (next). It may include work shelf identification information). As shown in FIG. 14, the guidance information after the work is completed may be typically displayed in the warning display area 38 of the workbench 13 corresponding to the production navigation system 10-1. However, the place where the guidance information after the work is completed is not limited.

On the other hand, in the production navigation system 10-2, it is assumed that the determination unit 163 determines that the work has been performed as shown in the scheduled work information acquired by the acquisition unit 161. At this time, since "-(none)" is set for the next work shelf of the front and rear work shelf information (FIG. 9), the presentation control unit 165 is for prompting the movement to the next shelf (after the work is completed). Guidance information) does not have to be displayed. Instead, the presentation control unit 165 may control the display unit 120 so that information indicating the completion of assembly of the product is displayed.

<2.3. Recording process>
The control device 11 (for example, the memory control unit 169) may record the state of work by the operator. For example, the control device 11 stores an image (still image / moving image) captured by the imaging unit 14 and / or the motion capture camera 20.

Then, the control device 11 analyzes the work contents of the worker based on the stored image. For example, the flow line of the worker, the orientation of the face, the distribution of the component mounting portion 21 that has been modified for collecting the component, the working time, and the like are analyzed. As a result, for example, the arrangement of the parts on the shelf 12 can be improved so that the parts mounting portion 21 which is frequently maintained for collecting the parts is distributed at a position where the hands can be easily accessed. The analysis result can be output to, for example, the administrator of the system 1.

<2.4. Process flow>
FIG. 15 is a flowchart showing an example of the flow of display processing by the production navigation system 10 according to the present embodiment. As shown in FIG. 15, first, the determination unit 163 determines whether the product number (work start information) attached to the work plan has been read by the code input unit 19 (step S100). When the determination unit 163 determines that the product number has not been read by the code input unit 19 (step S100 / NO), the determination unit 163 determines whether the product number (work completion information) has been received by the communication unit 110 (step S106). When the determination unit 163 determines that the product number (work completion information) has not been received (step S106 / NO), the process returns to step 100. On the other hand, when the determination unit 163 determines that the product number (work completion information) has been received (step S106 / YES), the process proceeds to step S108.

When the determination unit 163 determines that the product number has been read by the code input unit 19 (step S100 / YES), the determination unit 163 determines whether the shelf corresponding to the production navigation system 10 is the shelf on which the work should be performed first (step S100 / YES). Step S102). When the determination unit 163 determines that the shelf corresponding to the production navigation system 10 is not the shelf on which the work should be performed first (step S102 / NO), the presentation control unit 165 moves to the shelf on which the work should be performed first. The display unit 120 is controlled so that the information for prompting the movement of the above is displayed (step S104), and the process ends. At this time, the presentation control unit 165 may display the identification information of the shelf on which the work should be performed immediately before. On the other hand, when the determination unit 163 determines that the shelf corresponding to the production navigation system 10 is the shelf on which the work should be performed first (step S102 / YES), the process proceeds to step S108.

Subsequently, the presentation control unit 165 navigates the work on the shelf corresponding to the production navigation system 10 (step S108). Specifically, the presentation control unit 165 controls the display mechanism 15 so as to display the collection instruction information on the first plate-shaped member 33 and / or the second plate-shaped member 34. Next, the determination unit 163 determines whether or not the correct collection work has been performed (step S110). When it is determined that an erroneous collection operation has been performed (step S110 / NO), the presentation control unit 165 controls the display mechanism 15 to display the warning information (step S112). When the erroneously collected parts are returned to the component mounting unit 21, the display of the warning information is stopped, and the process returns to step S108. When it is determined that the correct collection work has been performed (step S110 / YES), the determination unit 163 determines whether or not the assembly work planned in the scheduled work information has been completed (step S114). If it is determined that the planned assembly work has not been completed (step S114 / NO), the process returns to step S108. On the other hand, when the determination unit 163 determines that the planned assembly work has been completed (step S114 / YES), the process proceeds to step S116.

Next, the determination unit 163 determines whether there is a shelf on which the work should be performed next to the shelf corresponding to the production navigation system 10 (step S116). Then, when it is determined that there is no shelf for the next work (step S116 / NO), the process ends. On the other hand, when it is determined that there is a shelf on which the work should be performed next (step S116 / YES), the presentation control unit 165 displays information for prompting the movement to the shelf on which the work should be performed next. The display unit 120 is controlled (step S118). At this time, the presentation control unit 165 may display the identification information of the shelf on which the work should be performed next. Further, the communication control unit 167 controls the communication unit 110 so that the product number (work completion information) is transmitted to the production navigation system 10 corresponding to the shelf on which the work should be performed next (step S119). After that, the process ends.

<< 3. Modification example >>
In the above embodiment, it has been described that the operator manually collects the parts, but the present invention is not limited to such an example. For example, an operator may operate a robot arm or the like to collect parts. In that case as well, the collection instruction information is displayed, the work status is determined, the warning information is displayed, and various guidance information is displayed in the same manner as when the worker manually works.

In the above embodiment, the collection instruction information, the warning information, and various guidance information are displayed, but the present invention is not limited to such an example. The collection instruction information, the warning information, and various guidance information may be output by any means such as sound or tactile stimulus together with or in place of the display. That is, the display unit 120 may be replaced with a presentation unit that presents collection instruction information, warning information, and various guidance information. At this time, the presentation control unit 165 may control the presentation unit so that the present information is presented by the presentation unit.

In the above embodiment, when the work on one shelf is completed and the product information (work completion information) is transmitted from the production navigation system corresponding to the next shelf, the product information in the production navigation system corresponding to the next shelf is transmitted. Will start navigation on the next shelf. At this time, the worker can recognize the next shelf by looking at the collection instruction information 61 displayed on the next shelf. However, when the work is performed by a plurality of workers at the same time, the collection instruction information 61 may be displayed on each of the plurality of shelves at the same time. Even in such a case, the worker can recognize the next shelf on which he / she should work by looking at the worker ID displayed on each shelf. Alternatively, the color of the collection instruction information 61 may be different depending on the worker ID who performs the work on the shelf.

In the above embodiment, the case where the scheduled work information on the shelf corresponding to the production navigation system 10 is stored for each production navigation system 10 has been described. However, the scheduled work information on the shelves corresponding to the plurality of production navigation systems 10 may be collectively stored by the server 90. In such a case, the determination unit 163 (for example, whether there is a shelf for which work should be performed next, or whether the shelf corresponding to the production navigation system is the shelf for which work should be performed first, etc.) is determined. Instead of the production navigation system 10, it may be done by the server 90.

In the above embodiment, the case where the work should be performed next to the shelf corresponding to the production navigation system has been described. However, a plurality of shelves may be set as shelves for which work should be performed next. In such a case, the worker may move to any of the plurality of shelves. In this regard, a plurality of shelves may be set as shelves on which work should be performed immediately before the shelves corresponding to the production navigation system. In such a case, the worker may move from any of the plurality of shelves.

In the above embodiment, the case where the work indicated by one scheduled work information is performed on only one shelf has been described. However, if the number of parts required for assembling the product is large, or if the size of each shelf is small, it is assumed that the work indicated by one scheduled work information may be performed on multiple shelves. Will be done. Therefore, the identification information of the shelf on which the work should be performed is also set in the work schedule information, and the presentation control unit 165 performs the work on any of the plurality of shelves based on the identification information of the shelf on which the work should be performed. You may navigate what to do.

<< 4. Hardware configuration >>
Each embodiment of the present invention has been described above. Information processing such as determination of the above-mentioned work status, display of collection instruction information, display of warning information, display of various guidance information, etc. is performed by cooperation between the software and the hardware of the production navigation system 10 described below. It will be realized.

FIG. 16 is a block diagram showing a hardware configuration of the production navigation system 10. The production navigation system 10 includes a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, and a host bus 204. Further, the production navigation system 10 includes a bridge 205, an external bus 206, an interface 207, an input device 208, a display device 209, an audio output device 210, a storage device (HDD) 211, a drive 212, and a network. It includes an interface 215.

The CPU 201 functions as an arithmetic processing unit and a control device, and controls the overall operation in the production navigation system 10 according to various programs. Further, the CPU 201 may be a microprocessor. The ROM 202 stores programs, calculation parameters, and the like used by the CPU 201. The RAM 203 temporarily stores a program used in the execution of the CPU 201, parameters that change appropriately in the execution, and the like. These are connected to each other by a host bus 204 composed of a CPU bus or the like. The CPU 201 can realize the function of the control unit 160 described above by performing the processing according to the software in the RAM 203.

The host bus 204 is connected to an external bus 206 such as a PCI (Peripheral Component Interconnect / Interface) bus via a bridge 205. It is not always necessary to separately configure the host bus 204, the bridge 205, and the external bus 206, and these functions may be implemented in one bus.

The input device 208 is an input means for an operator to input information such as a mouse, a keyboard, a touch panel, a button, a microphone, a switch, and a lever, and an input that generates an input signal based on the input by the operator and outputs the input signal to the CPU 201. It is composed of a control circuit and the like. By operating the input device 208, the operator can input various data to the production navigation system 10 and instruct the processing operation.
