Description

[Technical Field]

[0001] This specification discloses a picking guidance system and a picking guidance method. [Background technology]

[0002] Conventionally, there are known devices that provide guidance regarding the picking of materials such as products and parts. For example, Patent Document 1 describes a device that, when a worker places picked products into a container on a conveyor, indicates which container on the conveyor already has products placed in it by lighting a lamp or the like, thereby guiding the worker to which container to place the products. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-177423 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, materials required for a production job in a production area such as a factory are sometimes displayed in a picking guide, and workers are asked to pick them from a storage area such as a warehouse. While picking guidance is typically provided for the materials required for each production job, there may be cases where materials do not need to be picked because they were already picked in a previous production job. In such cases, including the material in the picking guide is undesirable because it would result in guidance for picking a material that does not exist in the storage area. On the other hand, excluding the material from the picking guide would prevent workers from recognizing that the material is required for the production job.

[0005] A primary object of the present disclosure is to enable recognition of each component allocated to a production job while providing appropriate guidance on components that require picking. [Means for solving the problem]

[0006] The present disclosure has adopted the following means to achieve the above-mentioned main object.

[0007] The picking guidance system of the present disclosure comprises: A picking guidance system that guides a worker in picking a component, an information acquisition unit that acquires information on components allocated to production jobs in the production area and location information on the location of the components; a guidance output unit that generates and outputs picking guidance for allowing a worker to pick the parts allocated to the production job from a storage area for the parts; Equipped with When generating the picking guide, if the component to be picked has location information of a component in an area different from the storage area, the guidance output unit indicates that picking of the component has been completed and includes this information in the picking guide. The gist of this is as follows.

[0008] In the picking guide system disclosed herein, when generating a picking guide, if the location information of the components to be picked is in an area other than the storage area, the picking guide indicates that the components have been picked and includes the information in the picking guide. Therefore, even if a component is included in the picking guide, the worker can understand that the component has already been picked and does not need to be picked. Furthermore, because the picking guide also includes components that do not need to be picked, the worker can recognize the components assigned to the production job by looking at the picking guide. Therefore, the worker can be appropriately guided to the components that need to be picked while being able to recognize each component assigned to the production job.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Next, an embodiment of the present disclosure will be described with reference to the drawings. FIG. 1 is a configuration diagram showing an outline of the configuration of a production system 10. The production system 10 includes an overall management device 20, a production management device 30, a mounting line 40 that performs mounting processing of components P, and a storage facility 50 that stores storage members such as reels R around which tape containing components P is wound. The mounting line 40 includes multiple mounting devices 41 that pick up components P from reels R or trays and mount them on boards S. In addition to the mounting devices 41, the mounting line 40 also includes a printing device that prints solder on the boards S and a reflow device that performs reflow processing on the boards S on which the components P are mounted. The storage facility 50 includes storage shelves 52 that store multiple members such as reels R.

[0011] In the production system 10, the overall management device 20 and the production management device 30 are communicatively connected to each mounting device 41 on the mounting line 40 via a network 12 such as a wired LAN or a wireless LAN. The overall management device 20 and the production management device 30 are also connected via the network 12 to a mobile terminal 60 carried by a worker M, a well-known printer 65 that prints various forms, and the like. The mobile terminal 60 is capable of displaying various types of information on a display screen, inputting various types of information using input buttons, and reading codes such as barcodes and two-dimensional codes attached to the reel R to obtain identification information.

[0012] The overall management device 20 is configured as a microprocessor centered around a CPU 21, and includes a memory unit 22 that stores various data, a communication unit 26 that communicates via the network 12, a display unit 27 that displays various information, and an input unit 28 such as a mouse or keyboard for inputting various instructions. The overall management device 20 exchanges information with the production management device 30, mobile terminal 60, etc. via communication via the communication unit 26. The memory unit 22 stores information related to work orders WO, which are production orders for the production system 10. The information related to the work orders WO includes, for example, information related to the type and quantity of boards S to be produced, delivery date, types of components P to be mounted on the boards S, and the required number of components.

[0013] The integrated management device 20 can also create a parts bill PL that lists the types and required quantities of parts P for each work order WO. FIG. 2 is an explanatory diagram showing an example of a parts bill PL. The parts bill PL includes, for each work order WO, part codes indicating the types of parts P required and the required quantities. Note that work orders WO1, WO2, and WO3 are produced in that order. The parts bill PL is printed as a slip by the printer 65 or displayed on the display screen of the mobile terminal 60. This allows the worker M to check the types and required quantities of parts P required for the work order WO from the parts bill PL. Note that in this embodiment, a picking guide for picking the reels R containing the required parts P from the storage warehouse 50 is output separately from the parts bill PL, as will be described in detail later.

[0014] The production management device 30 is configured as a microprocessor centered on a CPU 31 and includes a memory unit 32 for storing various data, a communication unit 36 ​​for communicating via the network 12, a display unit 37 for displaying various information, and an input unit 38, such as a mouse or keyboard, for inputting various instructions. The production management device 30 exchanges information with the overall management device 20, each mounting device 41 on the mounting line 40, and a mobile terminal 60 via communication via the communication unit 36. The memory unit 32 stores reel information related to the reels R in the production system 10. FIG. 3 is an explanatory diagram showing an example of the reel information 32a. The reel information 32a includes a reel ID, which is unique identification information for each reel R, the component code and remaining number of components P on the reel R, the location of the reel R, and information indicating whether the reel R has been picked from the storage 50. The production management device 30 appropriately updates the reel information 32a based on information from the mobile terminal 60 and each mounting device 41 on the mounting line 40.

[0015] Each mounting device 41 on the mounting line 40 includes a mounting control unit 42, a supply unit 43, a transport unit 44, a mounting unit 45, a communication unit 46, and an operation panel 47. The mounting control unit 42 is configured as a microprocessor centered on a CPU and includes a memory unit for storing various data. The mounting control unit 42 exchanges information with and controls the supply unit 43, transport unit 44, mounting unit 45, communication unit 46, and operation panel 47. The supply unit 43 is a unit that supplies components P to the mounting unit 45. The supply unit 43 has multiple slots for mounting feeders F with reels R attached, and also includes a tray unit that houses trays on which the components P are placed. The transport unit 44 is a unit that transports and fixes the board S. The mounting unit 45 is a unit that picks up the components P from the supply unit 43 and mounts them on the board S fixed to the transport unit 44. The mounting unit 45 includes a head equipped with a suction nozzle for picking up (sucking up) the component P, and a movement unit for moving the head in the X and Y directions. Note that the component P may be picked up by a mechanical chuck or the like. The communication unit 46 exchanges information with the production management device 30 and the like via the network 12. The operation panel 47 includes a display unit for displaying a screen, and an operation unit for receiving input from the worker M.

[0016] Here, the production system 10 of this embodiment has a shelf area A1, a picking area A2, an off-site setup area A3, and a line area A4. The shelf area A1 is a storage area where storage shelves 52 of a storage warehouse 50 are arranged. The picking area A2 is an area where reels R picked from the storage shelves 52 of the shelf area A1 are collected. The off-site setup area A3 is a preparation area where production preparations such as off-site setup in which a worker M assembles a reel R into a feeder F are performed. The line area A4 is a production area where a mounting line 40 is arranged and production is performed. Note that the location of the reel R before it is received in the storage warehouse 50 and stored in the shelf area A1 may be distinguished from the shelf area A1 and referred to as a warehouse area. The reel information 32a in FIG. 3 indicates that a reel R with location information of, for example, "A1-****" is in the shelf area A1, and the same applies to areas A2 to A4 other than the shelf area A1.

[0017] When worker M picks reel R from storage shelf 52, i.e., shelf area A1, he reads the code of reel R with mobile terminal 60. As a result, the reel ID of the reel R and information that it has been picked are transmitted to production management device 30. Furthermore, when worker M moves the picked reel R to picking area A2, for example by placing it in cart C in picking area A2, he reads the code of reel R with mobile terminal 60. As a result, the reel ID of reel R and location information that it is in picking area A2 are transmitted to production management device 30. Note that when reel R is picked from shelf area A1 and the code of reel R is read, the location information of reel R may be picking area A2.

[0018] Furthermore, when worker M transports reel R from picking area A2 to off-site setup area A3, worker M reads the code of reel R with mobile terminal 60. As a result, the reel ID of reel R and location information indicating that reel R is in off-site setup area A3 are transmitted to production management device 30. Note that when multiple reels R in cart C are moved collectively between areas, the code of cart C may be read with mobile terminal 60, and location information of each reel R in cart C may be transmitted collectively to production management device 30. In off-site setup area A3, worker M assembles reel R into feeder F, and then transports feeder F with assembled reel R to line area A4. When assembling reel R into feeder F, worker M reads the code of reel R with mobile terminal 60. As a result, information about the reel R assembled into feeder F is transmitted to production management device 30. Although not shown, the storage unit 32 of the production management device 30 stores assembly information of the feeder F and the reel R.

[0019] Furthermore, in line area A4, worker M attaches feeder F to the slot of supply unit 43 of mounting device 41. The task of attaching feeder F with reel R attached to it to mounting device 41 is also referred to as internal setup. Mounting control unit 42 acquires information about feeder F by communicating with the control unit of feeder F attached to the slot, and requests information about reel R from production management device 30 based on that information. Based on the reel ID identified by collating the assembly information, production management device 30 acquires the component code and remaining quantity from reel information 32a and sends them to mounting device 41. Based on the received reel ID, component code, and remaining quantity, mounting control unit 42 confirms whether the reel R is as allocated.

[0020] Next, various tasks and processes performed in the production system 10 configured as described above will be explained. First, an overview of the production work process in the production system 10 will be explained. FIG. 4 is an explanatory diagram showing an example of the production work process. In this production work process, the integrated management device 20 first registers the reel ID of the reel R received in the storage 50 or the like (S100). In S100, the unique reel ID of the reel R is registered by adding the identification code (management number) of the reel R to the component code of the component P stored in the reel R. Once the registration of the reel ID and other information is completed, the reel R is set to be available for allocation. In addition, information regarding allocation, such as the allocation status for each reel ID, is also confirmed.

[0021] Next, the production management device 30 creates a schedule for the mounting line 40 based on the information on the work orders WO stored in the integrated management device 20 (S110). In S110, a schedule is created that determines the timing of the start of production for each work order WO, the timing of picking and setup for that production, and the like, based on the production efficiency of the mounting line 40 and the number of boards S to be produced for each work order WO. The schedule also determines the type and required number of components P to be mounted by each mounting device 41.

[0022] Next, the production management device 30 executes allocation processing for the reels R according to the type and required number of components P (S120). As will be described in detail later, in the allocation processing, the reels R are allocated in units of reel ID, and it is also determined to which slot of each mounting device 41 the feeder F to which the reel R is attached will be attached. In addition, a picking slip showing picking instructions for the reels R and a setup change slip showing setup change instructions are issued. Once the picking slips are issued, the operator M performs picking work in the shelf area A1 (S130) and collects each picked reel R in the picking area A2.

[0023] Furthermore, when the reel R is transported to the off-site setup area A3, a worker M in the off-site setup area A3 performs off-site setup work (S140), and assembly information for the reel R and the feeder F is sent to the production management device 30. Meanwhile, the production management device 30 executes a transmission process to transmit a work order WO to the mounting line 40 (S150). The production management device 30 transmits the work order WO as needed based on the production schedule and the production status of the mounting line 40.

[0024] Then, when the feeder F (reel R) is transported to the line area A4, a worker M in the line area A4 performs internal setup work (S160). In S160, the worker M, while referring to the setup change slip and the screen display on the operation panel 47, installs the feeder F in the slot of each mounting device 41, and installs a tray on which tray components (not shown) are placed in the supply unit 43. Note that, on the mounting line 40, once it is confirmed that the required feeder F (reel R) has been installed in each mounting device 41, mounting processing based on the work order WO begins.

[0025] When the mounting process begins, the worker M in the line area A4 replenishes components as needed (S170). For example, the worker M checks the production status on the operation panel 47 or the mobile terminal 60 of each mounting device 41 and replenishes components P in the feeder F or tray components when they are in short supply. The worker M in the line area A4 also tidies up components by retrieving feeders F (reels R) from the mounting devices 41 that are no longer needed due to the end of production, for example (S180). The feeders F (reels R) retrieved in S180 are temporarily placed in the line area A4 or transported to the off-site setup area A3, depending on their planned use. The worker M in the off-site setup area A3 removes the reels R from the feeders F and transports the removed reels R to the picking area A2. The reels R transported to the picking area A2 are transported to the shelf area A1 as needed and stored on the storage shelves 52.

[0026] Next, the allocation process of S120 will be described in detail. FIG. 5 is a flowchart showing an example of the allocation process. In the allocation process, the CPU 31 of the production management device 30 first acquires the component type (component code) and required quantity of components P for each work order WO from the schedule created in S110 (S200). Next, the CPU 31 refers to the reel information 32a and allocates the reel ID of the reel R whose component type and remaining quantity correspond (S210). In S210, the reel information 32a is searched for a reel R whose component type matches and whose remaining quantity is equal to or greater than the required number, and the reel ID of that reel R is allocated. Note that, taking into account errors in the remaining quantity of components P, a reel R whose remaining quantity is equal to or greater than the required number plus a margin may be allocated.

[0027] Next, the CPU 31 acquires location information of the allocated reel R from the reel information 32a (S220) and determines whether the location information is in a different area from shelf area A1 (S230). When the CPU 31 determines that the reel R is in shelf area A1, it generates a picking guide indicating that picking is "yes" and that picking is "incomplete" to allow picking (S240). On the other hand, when the CPU 31 determines that the reel R is in a different area, it generates a picking guide indicating that picking is "yes" and that picking is "completed (automatic)" to make the user aware that picking is not necessary in shelf area A1 but is necessary for production (S250). In other words, the CPU 31 generates a picking guide indicating that picking is "yes" and that picking has already been completed, even though picking is not actually necessary.

[0028] Next, the CPU 31 determines whether picking guides have been generated for all reels R allocated to the work order WO (S260). If it determines that they have not been generated, the process returns to S220 and executes the process. On the other hand, if the CPU 31 determines that picking guides have been generated for all reels R, the CPU 31 outputs the generated picking guide (S270) and ends the allocation process. In S270, a picking slip (document) indicating the picking guide is printed by the printer 65, displayed on the display screen of the mobile terminal 60, or displayed on the display unit 37. The picking guide includes the reel ID, location information, and picking status of each reel R that has been "picked." When the picking guide is initially output, the picking status is displayed as either "incomplete" or "completed (automatic)." Furthermore, when an "incomplete" reel R is picked, the picking status is changed to "completed." In other words, the picking status is displayed as either "incomplete," "completed," or "completed (automatic)."

[0029] FIG. 6 is an explanatory diagram showing an example of the presence or absence of picking guidance in this embodiment, and FIG. 7 is an explanatory diagram showing the presence or absence of picking guidance in a comparative example. In FIGS. 6 and 7, the machine number of the mounting device 41, the slot number of the supply unit 43, the component code, and the reel ID are associated with each work order WO1 to WO3, and the presence or absence of picking guidance and the picking status are shown. In FIG. 6, for example, a reel R with a component code of "**01" and a reel ID of "**01-001" is set in slot 1 of the mounting device 41 with machine number 1 of work order WO1, indicating a picking "present" and "incomplete" status. Furthermore, since no reel R is set in slot 2, picking "not present" is shown. The same applies to other slots of work order WO1 and other work orders WO2 and WO3.

[0030] 6 and 7 illustrate an example in which, when work order WO1 is switched to work order WO2, reel R (feeder F) in slot 1 with a reel ID of "**01-001" is used as is, and picking is not required. In this embodiment, when creating a picking guide for work order WO2, it is determined that reel R with a reel ID of "**01-001" is in a different area, so a guide stating "Picking Required" and "Complete (Automatic)" is created, as shown in FIG. 6. Therefore, upon viewing the picking guide, worker M can recognize that reel R with a reel ID of "**01-001" (part P with a part code of "**01") will be used in work order WO2, even though picking is not actually required.

[0031] On the other hand, in the comparative example, only reels R that actually need to be picked are included in the picking guide. For this reason, as shown in Figure 7, in the picking guide for work order WO2, picking of reel R with "**01-001" is marked as "No," and reel R is not included in the picking guide. Therefore, even when worker M looks at the picking guide, he or she cannot recognize that reel R with reel ID "**01-001" (part P with part code "**01") will be used in work order WO2, and he or she will not be able to grasp part P required for production.

[0032] Here, the worker M may perform a so-called double check by checking the picked reel R (parts P) in both the picking guide and the parts bill PL (see FIG. 2). In this case, in the comparative example, a part P with a part code "**01" is included in the parts bill PL but not in the picking guide, resulting in an inconsistency between the picking guide and the parts bill PL. This prevents the worker M from checking the necessary parts P (reels R), hindering the work. On the other hand, in this embodiment, even if picking is not actually required, the part P is included in the picking guide as "completed (automatic)", preventing an inconsistency between the picking guide and the parts bill PL and allowing the worker M to reliably check the necessary parts P (reels R).

[0033] Here, the correspondence between the components of this embodiment and the components of the present disclosure will be clarified. The CPU 31 of the production management device 30 that executes S200 and S220 of the allocation process of this embodiment corresponds to the information acquisition unit of this disclosure, and the CPU 31 that executes S230 to S250 and S270 of the allocation process, the mobile terminal 60, and the printer 65 correspond to the guidance output unit of this disclosure. Furthermore, in this embodiment, by explaining the processing of the CPU 31, an example of the picking guidance method of the present disclosure will also be clarified.

[0034] In the production system 10 described above, if there is a reel R whose location information is in an area other than the shelf area A1, the fact that picking has been completed is indicated and included in the picking guidance. This allows the worker M to recognize each allocated reel R, while also properly guiding the reel R that actually needs to be picked.

[0035] Furthermore, even when the worker M uses both the parts bill PL and the picking guide, it is possible to prevent inconsistencies between the parts bill PL and the picking guide, and to allow the worker M to properly confirm the required parts P (reels R).

[0036] It goes without saying that the present disclosure is not limited to the above-described embodiments, and can be implemented in various forms as long as they fall within the technical scope of the present disclosure.

[0037] In the above-described embodiment, when the reel R is in an area other than the shelf area A1, automatic picking completion is indicated. However, this is not limited to this, and the following modified example may also be used. FIG. 8 is a flowchart showing allocation processing of a modified example. In the modified example, the same steps as in the embodiment are assigned the same step numbers, and descriptions thereof will be omitted. In FIG. 8, the CPU 31 acquires reel information for the reel ID allocated in S210 (S220b), and determines whether picking has been completed for another work order WO different from the currently allocated work order WO (S230b). If the CPU 31 determines that picking has not been completed for another work order WO, it executes the processing of S240 and proceeds to S260.

[0038] On the other hand, if the CPU 31 determines that the reel R has been picked for another work order WO, it generates a picking guide indicating that the reel R has been picked (automatically) by performing the process of S250. Next, the CPU 31 determines whether the reel R is in either the shelf area A1 or the picking area A2 (S252). The determination in S252 is a process for determining whether the reel R is in the shelf area A1 or the picking area A2, i.e., whether the picked reel R has not been transported to the off-site setup area A3. Furthermore, since the reel R has not been transported to the off-site setup area A3, this can also be considered a process for determining whether the reel R remains in the storage area where the reel R is placed before work (here, the shelf area A1 and the picking area A2).

[0039] When the CPU 31 determines in S252 that the reel R is in either the shelf area A1 or the picking area A2, it includes in the picking guide a notice of a delay in movement (transportation) to the next area (S254) and proceeds to S260. This makes it possible to alert the operator M by indicating in the picking guide that the reel R has been picked but not transported to the off-site setup area A3.

[0040] On the other hand, if the CPU 31 determines in S252 that the reel R is not in the shelf area A1 or the picking area A2, it determines whether or not production of another work order WO from which the reel R was picked has been completed (S256). If the CPU 31 determines that production of another work order WO has not been completed, it proceeds to S260. If the CPU 31 determines that production of another work order WO has been completed, it includes in the picking guidance a message indicating that production of the picked work order WO has been completed (S258), and proceeds to S260.

[0041] As a result, the picking guide indicates that there is a reel R that has been picked for another work order WO and that production of that other work order WO has already been completed. Here, for example, if a reel R that is no longer needed for production has been removed from the feeder F and temporarily placed in the off-site setup area A3, it may be picked from that temporary storage area. Therefore, by making the worker M aware that the reel R has already been picked for another work order WO and that production of that work order WO has been completed, it is possible to alert the worker M to the possibility that the reel R is in the temporary storage area.

[0042] In this modification, to further call the attention of the worker M, the worker M may be prompted to input that picking has been completed. In this case, in S250, a picking guide indicating that picking has been completed is generated, and a warning message is included in the picking guide in S254 or S258, prompting the worker M to input that picking has been completed. Even in this case, in order to indicate the difference from the normal picking guide in S248, the picking guide in S250 may be displayed in a different color from the picking guide in S248, or a specific message such as "Caution required" may be added to the picking guide to call attention.

[0043] Furthermore, in the modified example, it is determined in S252 whether the reel R is in either the shelf area A1 or the picking area A2, but this is not limited to this. For example, it may be determined in S252 whether the reel R is in the shelf area A1. In that case, the process of S254 is performed for the reel R that has been picked but not transported to the picking area A2. Furthermore, in the modified example, both the processes of S252 and S254 and the processes of S256 and S258 are performed, but it is also possible to perform one of the processes of S252 and S254 and the processes of S256 and S258 without performing the other.

[0044] In the embodiment, the allocated reel R is directly guided for picking, but this is not limited thereto. If a predetermined condition is met, a replacement reel that replaces the initially allocated reel R may be guided for picking. FIG. 9 is a flowchart showing an example of the replacement reel allocation process. This process may be executed, for example, after S210 of the allocation process. Alternatively, it may be executed when instructed by the worker M.

[0045] 9, the CPU 31 acquires reel information 32a of the allocated reel R and other reels R (S300). Next, the CPU 31 determines whether or not there is a specific reel R among the other reels R that has the same component code (component type) as any of the allocated reels R (S310), and if it determines that there is no specific reel R, the CPU 31 ends the replacement reel allocation process.

[0046] On the other hand, when the CPU 31 determines that there is a specific reel R, it determines whether the specific reel R is a reel R that has not been picked before (S320) and whether the remaining number of components P on the specific reel R is equal to or greater than the remaining number on the allocated reel R (S330). In S330, it may be determined whether the number of components P is equal to or greater than the required number when the reel R was allocated. Furthermore, the determination in S320 is a process of determining whether the specific reel R is a brand new reel R that has not been picked before. This is because if it is a brand new reel R, there is almost no possibility of an error in the remaining number of components P, which increases the reliability of the determination in S330. Note that the process of S320 is not limited to being performed, and the process of S320 may be omitted.

[0047] If the CPU 31 makes a negative determination in S320 or S330, it ends the replacement reel allocation process. Furthermore, if the CPU 31 determines that the remaining number of specific reels R is equal to or greater than the remaining number of allocated reels R and that the specific reel R has not been picked, it sets the specific reel R as a replacement reel (S340) and ends the replacement reel allocation process. After the replacement reel is set, the processes from S220 (S220b) onward are performed on the replacement reel, and picking guidance is provided. Note that, of the reels R allocated to one work order WO, multiple reels R may be set as replacement reels.

[0048] By making it possible to allocate a replacement reel in this way, if the initially allocated reel R becomes unavailable or cannot be picked for some reason, production can be carried out using another reel R. Examples of such reasons include the reel R being suddenly used for another work order WO, the parts P being consumed more than expected and resulting in a shortage of remaining parts, or a delay in production of the previously used work order WO causing preparation to be delayed. Alternatively, if a reel R that could be used as a replacement reel happens to be in the worker M's possession or is placed near the worker M, allocating a replacement reel can eliminate the effort of picking and allow work to be carried out more efficiently. The worker M may input the reel ID of the reel R that could be used as a replacement reel into the mobile terminal 60 or the like, and execute the process of FIG. 9 to determine whether the reel R can be used as a replacement reel.

[0049] In the embodiment, the reels R are allocated in units of reel IDs, but this is not limiting and they may be allocated in units of part codes or the like.

[0050] In the embodiment, the parts list PL can be output and the picking guide and the parts list PL can be checked, but this is not limited to this and the parts list PL does not have to be used. Also, the production system 10 is provided with two management devices (the general management device 20 and the production management device 30) to share functions and processes, but the sharing of functions and processes is one example and is not limited to the contents of the embodiment. Also, the production system 10 is not limited to having two management devices, but may have three or more management devices, or may have only one management device.

[0051] In the embodiment, reel R is used as an example of a material allocated to a production job, but this is not limited thereto and any material used in production and picked from a storage area may be used. For example, if the head of mounting unit 45 is configured to be detachable, this may be the head, or a suction nozzle attached to the head. Furthermore, as an example of production, a mounting process in which mounting device 41 mounts components P on board S is used. However, this is not limited thereto and other processes may be used, such as a process in which components are assembled by a multi-axis robot such as a vertical articulated robot.

[0052] Here, the picking guidance system of the present disclosure may be configured as follows. For example, the picking guidance system of the present disclosure is a picking guidance system that guides a worker in picking components, and includes: an information acquisition unit that acquires information on components assigned to production jobs in a production area and location information regarding the locations of the components; and a guidance output unit that generates and outputs picking guidance for the worker to pick the components assigned to the production jobs from a component storage area, where the information acquisition unit can acquire information that the components have been picked when the components are picked from the storage area, and the guidance output unit, if any of the components to be picked have already been picked in a production job other than the production job for which the picking guidance is generated, indicates that picking of the components has been completed and includes this information in the picking guidance. This allows the worker to recognize each component assigned to a production job while appropriately guiding the worker to components that need to be picked.

[0053] In the picking guidance system of the present disclosure, if the components to be picked include components that have already been picked in the other production job and whose location information is in the storage area, the guidance output unit may include information to that effect in the picking guidance. This allows the worker's attention to be drawn to components that have already been picked in the other production job but have not been moved from the storage area to another area.

[0054] In the picking guidance system of the present disclosure, if the material to be picked has already been picked for the other production job and production for that other production job has been completed, the guidance output unit may include information to that effect in the picking guidance. This allows the worker's attention to be directed to the material that has already been picked for the other production job and has been used for that other production job.

[0055] The picking guide system of the present disclosure may be used in a production system in which a list showing the components allocated to the production job can be checked by a worker while checking the picking guide. The picking guide includes components that do not require picking, so it can be matched with the list showing the components. Therefore, the worker can use the picking guide and the list showing the components to appropriately check whether picking of the components required for the production job has been completed.

[0056] In the picking guidance system of the present disclosure, the materials to be allocated to the production job may be allocated using an identification code indicating unique identification information assigned to each material, and the guidance output unit may generate the picking guidance by indicating the identification code of the material to be picked. In this way, picking guidance can be more appropriately provided when allocating materials based on the unique identification information.

[0057] In the picking guidance system of the present disclosure, the guidance output unit may be configured to generate picking guidance indicating alternative parts if there are alternative parts of the same type that meet the conditions for use in the production job. This increases the degree of freedom in selecting parts to be picked, allowing for more appropriate picking guidance.

[0058] The picking guidance method disclosed herein is a picking guidance method for guiding a worker in picking parts, and includes the steps of (a) acquiring information on parts assigned to production jobs in a production area and location information regarding the location of the parts, and (b) generating and outputting picking guidance for allowing a worker to pick the parts assigned to the production jobs from a parts storage area as picking targets, and in step (b), when generating the picking guidance, if the part to be picked has location information in an area other than the storage area, an indication that picking of the part has been completed is included in the picking guidance.

[0059] The picking guidance method of the present disclosure, like the above-described picking guidance system, can appropriately guide components that need to be picked while making it possible to recognize each component assigned to a production job. This picking guidance method may employ various aspects of the above-described picking guidance system, or may include additional steps that realize each function of the above-described picking guidance system.
