Furthermore, when the remaining number of predetermined components becomes equal to or less than the predetermined number during the execution of the mounting process by the component mounting machine 12, the host computer 30 etc. to that effect, and the operator H is notified of the part shortage notice. As a result, the operator H is encouraged to replenish the parts, and interruption of the mounting process due to running out of parts is prevented.

2-2. Configuration of Component Mounting Machine 12 The component mounting machine 12 executes mounting processing for mounting the component 73 (see FIG. 3) on the board 90 . As shown in FIG. 2, the component mounting machine 12 includes a substrate transfer device 21 that transfers the substrate 90 in the X direction. The substrate transfer device 21 is configured by a belt conveyor or the like. The substrate conveying device 21 sequentially conveys the substrates 90 in the conveying direction and positions the substrates 90 at predetermined positions within the apparatus. After completing the mounting process, the board transfer device 21 carries the board 90 out of the component mounting machine 12 .

The component mounting machine 12 includes a component supply device 22 that supplies components 73 to be mounted on the board 90 . In this embodiment, the component supply device 22 includes tape feeders 222 (hereinafter simply referred to as “feeders”) set in a plurality of slots 221 . The feeder 222 feeds and moves the component tape 70 (see FIG. 3) containing a large number of components 73 to supply the components 73 so as to be picked up. When the feeder 222 is loaded with a predetermined component tape 70, the identification information of the feeder 222 and the identification information of the component 73 are associated and stored in the production control device 51, which will be described later.

A plurality of components 73 accommodated in the same component tape 70 are of the same component type and are managed by the same identification information. Specifically, the plurality of components 73 are managed by, for example, identification information attached to a reel (not shown) around which the component tape 70 is wound. When the component tape 70 pulled out from a predetermined reel is loaded in the feeder 222, the component 73 having which component type and identification information is supplied from which feeder 222 by associating these identification information. or is grasped.

Further, the feeder 222 is classified into a general-purpose type and an auto-loading type. The general-purpose feeder 222 is provided with a tape conveying device that feeds and moves the component tape 70 so as to draw the component tape 70 in the vicinity of the supply position of the component 73, and requires loading of the component tape 70 by an operator.

The general-purpose feeder 222 requires a splicing operation to connect the supply component tape 70 to the loaded component tape 70 in use in order to prevent the component from running out during the mounting process. On the other hand, in the auto-loading type feeder 222, in order to prevent running out of components, it is necessary to insert the replenishment component tape 70 into the tape insertion port in an overlapping manner. The auto-loading type feeder 222 feeds and moves the supply component tape 70 after detecting that the rear end of the component tape 70 in use has passed through the tape insertion opening.

A mounting head 233 is exchangeably fixed to the moving table 232 by a clamp member (not shown).

The mounting head 233 movably supports one or more holding members that hold the component 73 supplied by the component supply device 22 . In this embodiment, the mounting head 233 supports multiple retaining members. As the holding member, for example, a suction nozzle 234 that sucks and holds the component 73 with supplied negative pressure air, a chuck that clamps and holds the component 73, or the like can be employed.

The component mounting machine 12 configured as described above performs a mounting process for mounting the component 73 on the board 90 . In the mounting process, the component mounting machine 12 controls the operation of the component transfer device 23 based on the information and measurement values output from various sensors, the result of image processing, the control program M4 for designating the mounting position on the board 90, and the like. to control. Thereby, the position and angle of the suction nozzle 234 supported by the mounting head 233 are controlled.

2-3. Constituent Devices of Production System 10 The production system 10 is composed of various constituent devices used for maintaining the production of board products by a plurality of production lines Lp. The production system 10 includes, as shown in FIG. 1, a production control device 51, a stocker 52, a plurality of carriages 53, a splicing device 54, and a terminal device 55, which are communicably connected to each other. The production management device 51 is communicably connected to the host computers 30 of the production lines Lp, and manages the production lines Lp, the stocker 52, and the like.

In addition, the production control device 51 functions as a scheduler for setting a production schedule for substrate products. The production control device 51 generates a setup list Fs used for setup work based on the production plan M1, product information M2, and inventory information M3 (see FIG. 4). Details of the setup work and the setup list Fs will be described later.

The production system 10 has a stocker 52 . The storehouse 52 is installed on the floor of the production factory and stores the parts used in the mounting process. The stocker 52 stores the components 73 in a state in which the component tape 70 is wound on a reel, or in a state in which the component tape 70 is loaded in the feeder 222, for example. Further, the stocker 52 recognizes the type and quantity of the stored parts by acquiring the identification information of the reels carried in and out or the identification information of the feeder 222 .

The production system 10 includes a carriage 53 . The carriage 53 accommodates a plurality of feeders 222 and is configured to be movable on the floor of the production factory. The carriage 53 is configured such that the feeder 222 can be accommodated in each of the plurality of accommodation units. The carriage 53 includes a type that travels by an external operating force and a type that travels by itself by a driving device.

In addition, the carriage 53 includes a general-purpose type that is mainly used for transporting a plurality of feeders 222 arranged in a plurality of component mounting machines 12 and preparation work, and a slot 221 that is connected to the component supply device 22 and has the above-described storage portion. There is a palette type that functions as a The carriage 53 may be configured to be communicable with the feeder 222 and the production control device 51 that accommodate any type.

Production system 10 includes a splicing device 54 . The splicing device 54 is used for the splicing work of connecting the ends of the pair of component tapes 70 . Here, the component tape 70 accommodates one component 73 in each of a plurality of cavities 711 formed in the base tape 71 at regular intervals, as shown in FIG. The openings of the plurality of cavities 711 are closed by the cover tape 72 to prevent the component 73 from falling off. The base tape 71 is formed with feed holes 712 that engage teeth of sprockets of the feeder 222 and the tape conveying device of the splicing device 54 .

In this embodiment, as shown in FIG. 3, the splicing device 54 joins the ends of a pair of component tapes 70 by affixing the splicing tape with the ends of the component tapes 70 facing each other. The pair of component tapes 70 is assumed to be, for example, the component tape 70 in use or to be used loaded in the feeder 222 and the component tape 70 for replenishment. The splicing tapes described above are composed of, for example, a front splicing tape 81 and a back splicing tape 82 which are detachably attached to the supply tape 80 .

The splicing device 54 is configured to be movable on the floor of the production plant, and is driven by an external operating force. Also, the splicing work is executed based on the advance notice of component shortage notified from the host computer 30 in the mounting process by the component mounting machine 12 in which the general-purpose type feeder 222 is set. Furthermore, the splicing work can also be performed appropriately in the setup work of the component mounting machine 12 . When the splicing work is performed, the remaining number of parts 73 loaded in the feeder 222 is updated, and the remaining number information is shared in the production system 10 .

The production system 10 has a terminal device 55 . The terminal device 55 is a tablet carried by the worker H, for example. It is communicably connected to the production control device 51 . The terminal device 55 displays various information such as the setup list Fs input from the production control device 51 . In addition, the terminal device 55 can receive various operations by the worker H and request the production control device 51 to output predetermined information.

3. Generation of Setup List Fs by Production Control Device 51 The production control device 51 of the production system 10 functions as a scheduler for setting the production schedule of the substrate product, as described above. That is, the production control device 51 sets the product type, quantity, production order, etc. of the board products to be produced in each of the plurality of production lines Lp based on the production plan M1 and the product information M2.

Here, as shown in FIG. 4, the above production plan M1 is a target production quantity ( T1, T2, T3, . . . ). Further, the product information M2 includes the part types (Pa, Pb, Pc, Pd, . indicates In other words, the product information M2 indicates, for each part type, the number of parts consumed when producing one board product of a predetermined product type.

Also, after setting the production schedule, the production control device 51 sets setup work required for each production based on the inventory information M3. Here, the above-mentioned "setup work" refers to work to make the planned production in the current production line Lp executable. The setup work for the component mounting machine 12 includes, for example, the work of loading the component tape 70 into the feeder 222 and the work of storing the feeder 222 in the general-purpose type or pallet type carrier 53 .

The setup work includes a work of setting the feeder 222 taken out from the general-purpose type carrier 53 into a predetermined slot 221 of the component supply device 22 and a work of setting the pallet type carrier 53 in the component supply device 22. included. The production control device 51 generates a setup list Fs used for setup work set for each production based on the inventory information M3.

Here, the inventory information M3 indicates the inventory quantity of the component 73 for each identification information (ID), as shown in FIG. For example, when the component tape 70 is wound on different reels for the same component type, the same component type is managed with different identification information, as shown in the inventory information M3. In addition, the above-mentioned "inventory quantity" includes the quantity of the parts 73 stored in the stocker 52 and the quantity of the parts 73 accommodated in the carrier 53 .

Furthermore, the inventory quantity of the components 73 includes the quantity of the components 73 loaded in the feeder 222 set in the component mounting machine 12 in the stopped state at the start of the scheduled setup work. may Then, the production management device 51 applies the predetermined parts 73 to the mounting process executed in the set production schedule. At this time, when a plurality of pieces of identification information are associated with the same part type (that is, when a plurality of reels are stored), the production control device 51 selects the part 73 based on a predetermined application condition, for example. apply.

The application conditions include, for example, the purchase timing of the parts 73, the remaining number of the parts 73 with respect to the required number in the mounting process, the management status of the parts 73, and the part information such as the supplier of the parts 73. For example, the production control device 51 preferentially applies parts 73 with a small quantity among the parts 73 in stock, or preferentially applies parts 73 loaded in the feeder 222 so as to reduce the man-hours for setup work. It is assumed that

The production control device 51 generates a setup list Fs indicating identification information of the components 73 to be applied to the mounting process by the component mounting machine 12 among the components 73 in stock. The production management device 51 presents the operator H with a setup list Fs as shown in FIG. 4, for example, to instruct the setup work of the component mounting machine 12 that executes the mounting process in the production schedule.

Here, the setup list Fs indicates identification information (ID) of the component 73 to be set for each slot 221 of the component supply device 22 in the component mounting machine 12 that executes the predetermined mounting process. In the present embodiment, the setup list Fs includes, for example, component types (Pa, Pb, . . . ) corresponding to identification information (ID) in order to improve workability of setup work. In addition, the setup list Fs may include identification information of the feeder 222, location information of the component 73, and the like.

4. Configuration of Setup Support Device 40 The setup support device 40 supports setup work based on the setup list Fs. In this embodiment, an aspect in which the setup support device 40 is incorporated in the host computer 30 in a plurality of production lines Lp will be described as an example. Here, the component mounting machine 12 that produces the board product is set with the component 73 in the predetermined slot 221 by executing the setup work before executing the mounting process.

In addition, when the remaining number of predetermined components 73 becomes equal to or less than the specified number Nr during execution of the mounting process, the worker H can H is notified of the part shortage notice. The “remaining number” of the parts 73 described above is the quantity of the parts 73 associated with the same identification information (ID). The remaining number of components 73 corresponds to, for example, the number of components 73 set in the component mounting machine 12, and gradually decreases as the mounting process progresses. Also, the remaining number of parts 73 increases due to replenishment work such as splicing work. Moreover, the above-mentioned "specified number Nr" is a quantity that is arbitrarily set in consideration of the time required for the replenishment work of the parts 73 and the like. The specified number Nr can be set to a common quantity in the production line Lp, or a different quantity depending on the type of parts or the type of replenishment work, for example.

The replenishment work includes a splicing work of splicing the replenishment component tape 70 to the component tape 70 loaded in the general-purpose feeder 222 . Also included is the work of inserting the replenishment component tape 70 into the tape insertion port of the auto-loading type feeder 222 . In addition, if the feeder 222 is of stick type, the replenishing work includes replenishing the stick holding the part 73 .

The worker H specifies the production line Lp, the component mounter 12, and the slot 221 where the component shortage occurs by the component shortage notice, and replenishes the component 73 by replenishment work according to the type of the feeder 222 and the component type. By completing the replenishment work of the parts 73 before the parts run out, interruption of the mounting process due to the parts run out can be prevented. However, during production on the production line Lp, there are cases where a plurality of component shortage notices are notified in a short period of time. As a result, the replenishment work of the parts 73 is stagnant, and there is a possibility that the parts may run out.

One of the reasons why the component depletion notice is notified in a short period of time as described above is that the timing of the component depletion notice (i.e., the timing when the remaining number of the components 73 becomes equal to or less than the specified number) is set in the setup list Fs generation. It is assumed that it is not included in the applicable conditions of the above, or the priority as the applicable conditions is low. Therefore, the setup support device 40 of the present embodiment adopts a configuration capable of suppressing the stagnation of the supply work of the components 73 during the execution of the mounting process of the component mounting machine 12 and maintaining a suitable production state.

Specifically, the setup support device 40 includes a storage device 41 as shown in FIG. Storage device 41 stores setup list Fs generated by production control device 51 and inventory information M3. Moreover, in this embodiment, the storage device 41 stores the production plan M1 and the product information M2. Furthermore, in this embodiment, the storage device 41 stores a control program M4 and part data M5.

The control program M4 indicates the mounting positions and the mounting order of the components 73 to be mounted on the board 90 in the mounting process. Specifically, in the control program M4, as shown in FIG. 4, the mounting position (coordinates) of the component 73 is associated with the mounting angle of the component 73 and the component type. The above-mentioned mounting coordinates (X-axis coordinates (X11, X12, X13, X14, . . . ), Y-axis coordinates (Y11, Y12, . . . )) are values indicating the position where the component 73 is mounted on the board 90. be. The mounting angle (θ-axis angle (θ1, θ2, θ3, θ4, . . . )) of the component 73 is a value indicating the angle of the component 73 on the mounting coordinates.

The part data M5, as shown in FIG. 4, indicates the movement speed (V11, V12, V13, . . . ) of the part 73 set for each part type. The moving speed of the component 73 may indicate a ratio to the maximum moving speed of the mounting head 233 in the component mounting machine 12 . Further, the part data M5 indicates the acceleration (A11, A12, A13, . . . ) of the part 73 set for each part type.

The component mounting machine 12 operates the mounting head 233 so as not to exceed the movement speed and acceleration set for each component type when holding the component 73 of a predetermined component type and moving it onto the substrate 90 in the mounting process. to control. As a result, the component mounter 12 prevents the component 73 from falling off and maintains mounting accuracy.

The setup support device 40 includes a calculator 42 as shown in FIG. The calculation unit 42 calculates the supply time Ts from when the mounting process is started in the component mounting machine 12 that has performed the setup work based on the setup list Fs until the remaining number of components 73 in the component mounting machine 12 becomes equal to or less than the specified number Nr. , is calculated for each identification information based on the setup list Fs and inventory information M3 before execution of the mounting process.

In other words, the above-mentioned "supply time Ts" corresponds to the time during which the component mounting machine 12 that has properly performed the setup work can supply the component 73 and execute the mounting process. Further, the supply time Ts can also be said to be the time from when the mounting process is started until when the remaining number of the parts 73 reaches the specified number Nr and the advance notice of the part shortage is notified. The supply time Ts is an estimated time calculated by the calculator 42 based on the setup list Fs and the inventory information M3.

In this embodiment, the calculation unit 42 calculates the supply time Ts based on the quantity of the parts 73 required for execution of the mounting process calculated based on the production plan M1 and the product information M2, the setup list Fs, and the inventory information M3. do. That is, when calculating the supply time Ts, the calculator 42 first recognizes which substrate product (product type) is to be produced based on the production plan M1. Next, based on the product information M2, the calculation unit 42 recognizes the number of parts consumed when producing one board product of the product type for each part type. Then, the calculation unit 42 calculates the supply time Ts based on the remaining number of the parts 73 and the number of parts to be consumed immediately after execution of the setup work. Thereby, the supply time Ts can be calculated more accurately.

In this embodiment, the calculator 42 further calculates the supply time Ts based on the required time Rc for the mounting process calculated based on the control program M4 and the part data M5, the setup list Fs, and the inventory information M3. That is, when calculating the supply time Ts, the calculator 42 first calculates the moving distance of the mounting head 233 based on the mounting position included in the control program M4. Next, the calculation unit 42 calculates the time required for movement of the mounting head 233 based on the moving distance of the mounting head 233 and the moving speed included in the part data M5.

Then, the calculator 42 calculates the time required for a pick-and-place cycle (hereinafter referred to as a "PP cycle") including the picking operation and the mounting operation of the component 73 by the mounting head 233 in the mounting process. The calculation unit 42 calculates the supply time Ts based on the required time for each PP cycle that is executed multiple times in the mounting process. Thereby, the supply time Ts can be calculated more accurately.

Here, the calculation unit 42 calculates the supply time Ts based on the production plan M1 and the product information M2 as described above. Two embodiments are illustrated. The calculator 42 may employ only one of the first mode and the second mode. Further, the calculation unit 42 calculates the remaining number of parts 73 immediately after execution of the setup work based on, for example, the setup list Fs and the inventory information M3, and multiplies the remaining number by a preset constant to determine the supply time. Ts may be approximated.

The setup support device 40 includes a determination unit 43 as shown in FIG. Based on the supply time Ts calculated by the calculation unit 42, the determination unit 43 determines whether or not additional supply of the component 73 is necessary in the setup work for each identification information. Here, "additional replenishment" corresponds to a replenishment work that is performed in addition to the replenishment work described above so as to increase the remaining number of parts 73 in the setup work.

For example, when the general-purpose feeder 222 is set in the predetermined slot 221 in the setup work based on the setup list Fs, the additional supply of the component 73 is performed by adding the component tape 70 for supply to the component tape 70 loaded in the feeder 222. It is a splicing operation to splice. In addition, the additional replenishment includes the operation of inserting the component tape 70 for replenishment into the tape insertion port of the autoloading type feeder 222 . In addition, if the feeder set in the slot is of the stick type, the additional replenishment includes replenishing sticks holding the parts 73 .

In this embodiment, when the supply time Ts calculated by the calculation unit 42 is shorter than a preset threshold value Th, the determination unit 43 determines that additional supply of the components 73 is required in the setup work. Specifically, since the supply time Ts from the start of the mounting process until the remaining number of the predetermined parts 73 becomes equal to or less than the specified number Nr and the advance notice of the parts shortage is notified is shorter than the threshold Th, the mounting process is started. replenishment work is required relatively early. Therefore, the determination unit 43 determines that additional supply is necessary for such a component 73, as it is more efficient to perform additional supply in advance in the setup work.

Further, in the present embodiment, when the difference ΔT between the two supply times Ts calculated for the two types of components 73 is shorter than the required time Rs for additional supply, the determination unit 43 determines that the two types of components in the setup list Fs It is determined that at least one part 73 of 73 needs additional supply. Specifically, while the remaining number of one of the two types of components 73 is less than the specified number Nr after the mounting process is started and the replenishment work is being performed, the advance notice of the lack of the other component is notified. It is recognized that replenishment work may be delayed in the future if there is Therefore, the determination unit 43 determines that such two types of components 73 require additional replenishment because it is more efficient to perform additional replenishment in advance in the setup work.

The setup support device 40 includes a presentation unit 44 as shown in FIG. The presentation unit 44 presents guidance information Fg including the determination result by the determination unit 43 . In other words, the presentation unit 44 presents the operator H or the like with the result of determination by the determination unit 43 as to whether or not additional supply of the component 73 is necessary in the setup work. Various aspects can be adopted for the presentation by the presentation unit 44 . In this embodiment, as shown in FIG. 4, the presentation unit 44 presents the guide information Fg by adding it in correspondence with the identification information in the setup list Fs.

Specifically, the presentation unit 44 puts a mark "○" in the column of "additional supply" in the guidance information Fg for the parts 73 determined to require additional supply, and for parts determined not to require additional supply. "-" is attached. Here, by properly executing at least the setup work specified by the setup list Fs, the mounting process in the production line Lp satisfies the conditions for starting the execution. In other words, the necessity of additional replenishment presented by the presentation unit 44 indicates the necessity of work recommended for maintaining a suitable production state in the production line Lp, rather than the condition for starting the mounting process.

Here, the worker H performs the setup work while referring to the setup list Fs. By adding the guide information Fg to such a setup list Fs, the visibility of the information is improved, and the operator H can easily grasp the parts 73 that require additional replenishment. Further, the guide information Fg presented by the presenting unit 44 may present various information in addition to the necessity of additional replenishment (◯/−).

In this embodiment, the guide information Fg includes the supply time Ts calculated by the calculator 42 . According to such a configuration, the operator H, who is presented with the guidance information Fg, grasps how much time has elapsed since the start of the mounting process of the parts 73 recommended for additional replenishment before being notified of the part shortage. can do. As a result, the worker H can intuitively grasp the need for additional supply in the setup work, taking into consideration the work situation during the time zone in which the advance notice of parts shortage is notified, for example.

Further, in the present embodiment, the guidance information Fg includes the part type and remaining number of the part 73 corresponding to the identification information. According to such a configuration, the worker H or the like presented with the guide information Fg can easily grasp the parts 73 determined to require additional supply. Also, by grasping the remaining number of components 73 set on the component mounting machine 12 by the setup work, for example, the length of the component tape 70 wound on the reel and the need for additional replenishment in the setup work can be sensed intuitively. can be grasped.

Furthermore, in the present embodiment, the guidance information Fg includes the priority of additional replenishment set based on the supply time Ts. According to such a configuration, the worker H or the like presented with the guidance information Fg can select which part 73 in a limited work time when there are a plurality of parts 73 determined to require additional replenishment, for example. It can be used as a judgment index as to whether it should be performed preferentially. As a result, the operator H can preferentially perform additional replenishment, for example, which is particularly necessary.

5. Setup Support Processing Setup support processing using the setup support device 40 will be described with reference to FIG. First, the setup support device 40 acquires the setup list Fs and various data (M1-M5) from the production control device 51 that generated the setup list Fs (S11). The storage device 41 stores the obtained setup list Fs and various data (M1-M5).

Next, the calculator 42 calculates the supply time Ts for each identification information (ID) of the component 73 included in the setup list Fs (S12). The calculation unit 42 sets data used for calculating the supply time Ts from various data (M1 to M5) based on parameters indicating the required accuracy of the supply time Ts, the time required for calculation, and the like. The above parameters may be set so as to vary according to, for example, the type of part, the frequency of use in the mounting process, the remaining number of parts 73, and the like.

Subsequently, the determination unit 43 executes determination processing for determining whether or not additional supply of the component 73 is necessary in the setup work for each identification information (ID) (S20). Specifically, first, when the supply time Ts of the component 73 having the predetermined identification information is shorter than the threshold value Th (S21: Yes), the determination unit 43 determines that additional supply of the component 73 is necessary. , is stored in association with the identification information (S22).

If the above processes (S21, S22) have not been performed for all of the identification information (S23: No), or if the supply time Ts of the component 73 is equal to or greater than the threshold Th (S21: No), the determination unit 43 The above processing (S21, S22) is repeated for the part 73 having the undetermined identification information. On the other hand, if the above processes (S21, S22) have been performed for all of the identification information (S23: Yes), the determination unit 43 selects an arbitrary are extracted, and the difference ΔT between these supply times Ts is calculated (S24).

If the difference ΔT between the supply times Ts of the two types of components is shorter than the required time Rs for additional supply (S25: Yes), the determination unit 43 determines that at least one of the two types of components 73 is additionally supplied. is required, and stored in association with the 1 or 2 identification information determined to be required (S26). In the determination process (S25) above, the determination is made by comparing the difference ΔT of the supply time Ts and the required time Rs for additional replenishment. good.

If the above processing (S24-S26) has not been performed for all combinations for extracting two types of identification information (S27: No), the determination unit 43 performs the above processing for parts 73 corresponding to combinations of different identification information. (S24-S26) are repeated. If the difference ΔT between the supply times Ts is equal to or greater than the required time Rs for additional supply (S25: No), the determination unit 43 repeats the above processes (S24-S26).

On the other hand, if it is determined whether additional replenishment is necessary for all the identification information in the setup list Fs (S27: Yes), the determination processing (S20) by the determination unit 43 ends. Subsequently, when there are a plurality of pieces of identification information determined to require additional supply, the presentation unit 44 calculates the priority of each additional supply (S31). The presentation unit 44 sets the priority so that the shorter the supply time Ts of the component 73 determined to require additional supply, the higher the priority.

In addition to or instead of the supply time Ts, the presentation unit may set the priority based on the required time Rc of each mounting process in the plurality of component mounters 12, for example. For example, if the component mounting machine 12, which requires a relatively long time Rc to mount one substrate 90 in the production line Lp, runs out of components, it may affect the production line Lp as a whole. is of high importance. On the other hand, in the component mounting machine 12 having a relatively short required time Rc for the mounting process, even if components run out, it is possible to recover during the waiting time for transporting the board 90, and the production line Lp as a whole can be recovered. The impact is expected to be small.

Subsequently, the presentation unit 44 generates guidance information Fg (S32). As items to be included in the guide information Fg, in addition to the necessity of additional replenishment, the supply time Ts, the remaining number of the parts 73 set by the setup work, the priority, etc., are appropriately added by user setting, for example. The presentation unit 44 presents the guide information Fg by adding it in correspondence with the identification information in the setup list Fs (S33).

The setup list Fs is sent from the host computer 30 to the production control device 51 and the terminal device 55 carried by the worker H (in addition, the setup list Fs may be displayed on the display provided in the host computer 30). good). The worker H performs the setup work according to the setup list Fs displayed on the terminal device 55 . Further, in the setup work, the operator H confirms whether or not additional replenishment is necessary based on the guidance information Fg, and appropriately performs additional replenishment. Note that when the additional supply is executed, the remaining number of components 73 loaded in the feeder 222 is updated.

6. Effect of Configuration of Embodiment In this embodiment, the calculation unit 42 of the setup support device 40 calculates the component 73 in the component mounting machine 12 after the component mounting machine 12 that has performed the setup work based on the setup list Fs starts the mounting process. The supply time Ts until the number of remaining items becomes equal to or less than the specified number Nr is calculated for each identification information based on the setup list Fs and the inventory information M3 before execution of the mounting process. Based on the calculated supply time Ts, the determination unit 43 determines for each identification information whether additional supply of the component 73 is necessary in the setup work.

According to such a configuration, the determination result serves as an indicator of whether or not additional replenishment is to be performed in addition to the normal replenishment of the parts 73 in the setup work targeting the parts 73 that require replenishment early after the start of the mounting process. can be obtained. As a result, for example, it is possible to additionally replenish components in the setup work in advance, and it is possible to suppress the stagnation of the component replenishment work during execution of the mounting process. As a result, it is possible to maintain a favorable production state.

7. Modification of Embodiment 7-1. Regarding Determination of Necessity of Additional Supply In the determination process (S20) of the embodiment, the determination unit 43 makes a determination (S21) by comparing the supply time Ts and the threshold value Th, and determines the difference ΔT between the supply time Ts and the required time Rs. A configuration is adopted in which determination (S25) is performed by comparison. On the other hand, the determination unit 43 may determine whether additional replenishment is necessary by any one of the above modes.

Also, the threshold Th used in the determination process (S20) may be a fixed value set by the user, or may be set for each part type. Further, the threshold value Th is set in consideration of the required time Rc for the mounting process, the required time for the maintenance process executed after a predetermined number of process cycles (for example, the PP cycle, the transfer process of the substrate 90), and the like. It may be set as Further, the required time Rs for additional replenishment may be the time required for the splicing work, or may include the time required for moving the splicing device 54 and the preparation time.

7-2. Presentation of Guide Information Fg In the embodiment, the presentation unit 44 is configured to present the generated guide information Fg to the operator H or the like by adding it to the setup list Fs. On the other hand, the presenting unit 44 may present the guide information Fg in another mode in addition to adding it to the setup list Fs or in place of it. For example, the presenting unit 44 displays the guide information Fg on the terminal device 55 separately from the setup list Fs, or displays it on the display device (not shown) of the component mounting machine 12 during the execution of the setup work. You may

Further, after presenting that additional replenishment is required, the setup support device 40 further selects the parts 73 (specifically, corresponding You may guide the reel etc.) at the same time. Furthermore, the setup support device 40 may present the current location of the part 73 used for additional supply and information on the part 73 (identification information, part type, remaining number, etc.).

With the above configuration, when the worker H decides to perform additional replenishment using the guided parts 73, the setup support device 40 stores the corresponding parts in the storage box 52 having the automatic dispensing function. 73 may be ordered to be paid out. As a result, the production system 10 can dispense the parts 73 required for additional supply in addition to the dispense of the parts 73 based on the setup list Fs, thereby improving work efficiency.

7-3. About Setup Support Device 40 In the embodiment, the setup support device 40 is configured to be incorporated in the host computer 30 provided in each of the plurality of production lines Lp. On the other hand, the setup support device 40 may be provided outside the host computer 30 as long as the setup list Fs and inventory information can be obtained.

For example, the setup support device 40 may be configured to be incorporated in the production control device 51, the storage 52, and the terminal device 55, or may be configured as a single external device capable of communicating with these devices. In the setup support device 40, the storage device 41 is shared with the production control device 51 and the storage device of the host computer 30, and at least a part of the calculation unit 42, the determination unit 43, and the presentation unit 44 are external devices.
