Description

Management device, mobile work device, mounting system, management method, and mobile work device control method

[0001] This specification discloses a management device, a mobile work device, a mounting system, a management method, and a method for controlling a mobile work device.

[0002] A mounting system has been proposed in the past in which, of multiple feeders required for the mounting process, some feeders to be initially set are set in the supply area of ​​the component mounting device, and the mounting process is started in a state in which the remaining feeders are not set in the supply area, and the feeders that have finished supplying components are replaced with the remaining feeders by a mobile work device while the mounting process is carried out (see, for example, Patent Document 1). With this mounting system, the mounting process can be carried out while replacing the feeders with the necessary ones within the upper limit of the number of feeders that can be installed on the mounting device, thereby improving the efficiency of the mounting process.

[0003] International Publication No. 2017 / 085782

[0004] Incidentally, in some mounting systems, a group of feeders to be initially set up as described above may be replaced en bloc as a common setup during mounting processing. This mounting system can minimize internal setup time, leading to greater efficiency. However, in the mounting system of Patent Document 1, feeders not currently in use are moved to a standby mounting unit serving as a stock area, which means that the common setup is not maintained and the feeders cannot be replaced en bloc. There is a need for greater efficiency in such mounting systems.

[0005] The main object of the present disclosure is to provide a management device, a mobile work device, a mounting system, a management method, and a method for controlling a mobile work device that can achieve greater efficiency in a mounting system that automatically replaces feeders.

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

[0007] The management device disclosed herein is a management device used in a mounting system including a mounting device having a mounting unit that mounts components on processing objects, a supply unit that has a mounting mounting unit to mount a feeder holding the components and supplies the components, and a mounting control unit that causes the components to be picked up from the supply unit to the mounting unit, and a mobile work device that automatically exchanges the feeders between a standby mounting unit that is not capable of mounting and the mounting mounting unit, and the management control unit is configured to output a recovery command to the mobile work device to move the feeders included in the common setup that are not in the mounting mounting unit to the mounting position of the common setup at a predetermined timing when production of the processing objects by the common setup is completed after the feeders based on a common setup that mounts the feeders holding common components at positions common to the production of multiple types of the processing objects are mounted on the mounting mounting unit.

[0008] In this management device, if a feeder for the common setup is not present in the mounting attachment section at a predetermined timing when production of the processing object using the common setup is completed, a recovery command is output to the mobile work device to move the feeder to the attachment position for the common setup. Since this management device restores the feeder arrangement for the common setup when production using the common setup is completed, it is possible to replace feeders all at once, and by shortening internal setup time, it is possible to achieve greater efficiency.

[0010] This embodiment will be described below with reference to the drawings. Fig. 1 is a schematic explanatory diagram showing an example of a mounting system 10 according to the present disclosure. Fig. 2 is an explanatory diagram showing an outline of the configuration of a mounting device 15 and a loader 18, which is a mobile work device. Fig. 3 is an explanatory diagram showing an example of production plan information 44 stored in a storage unit 43 of a management device 14. In this embodiment, the left-right direction (X-axis), front-back direction (Y-axis), and up-down direction (Z-axis) are as shown in Figs. 1 and 2.

[0011] The mounting system 10 is configured as a production line in which, for example, devices for mounting components P on a substrate S as an object to be processed shown in Fig. 2 are arranged in the transport direction of the substrate S. Here, the object to be processed is described as a substrate S, but is not particularly limited as long as it is something on which components P can be mounted, and it may also be a substrate with a three-dimensional shape. As shown in Fig. 1, the mounting system 10 is configured to include a printing device 11, a print inspection device 12, a storage device 13, a management device 14, a mounting device 15, a mounting inspection device 16, an automatic guided vehicle 17, a loader 18, a reflow device 19, and a supervision device 60.

[0012] The printing device 11 is a device that prints a viscous fluid such as solder paste, conductive paste, or adhesive on a substrate S. The print inspection device 12 is a device that inspects the state of the printed viscous fluid. The storage device 13 is a storage location that stores feeders 25 as supply members used in the mounting device 15. The storage device 13 is provided at the front lower part of the transport device between the print inspection device 12 and the mounting device 15. The management device 14 is a device that manages the feeders 25 stored in the storage device 13. The mounting inspection device 16 is a device that inspects the state of components P mounted on the substrate S. The reflow device 19 is a device that reflows the substrate S on which the viscous fluid has been printed and the components P have been mounted.

[0013] As shown in FIG. 1 , the storage device 13 is a device that temporarily stores feeders 25 as supply devices used in the mounting device 15. The storage device 13 has a transport device that transports the board S and a management device 14 that manages information, and is provided between the print inspection device 12 and the mounting device 15. The storage device 13 is equipped with a storage mounting section that has slots 28 and connection sections 29 similar to the mounting mounting section 26 and buffer mounting section 27 of the component supply unit 24 described below. When the feeder 25 is connected to this mounting section, the controller of the feeder 25 outputs information about the feeder 25 to the management device 14 connected to the storage device 13. In addition to being transported to the storage device 13 by an automated guided vehicle 17, the feeder 25 may also be transported by a worker W.

[0014] The management device 14 is disposed in the storage device 13 and configured as a server that manages information about the mounting device 15 of the mounting system 10. The management device 14 includes a management control unit 41 that controls the entire device, a memory unit 43 that stores various information, a communication unit 48 that performs two-way communication with external devices such as the automatic guided vehicle 17 and the loader 18, and a display unit 49 that displays the upper part on a screen. The management device 14 creates and manages production plan information 44 used in the mounting process of the component P and mounting jobs 45 included in the production plan information 44, as well as acquires and manages information about the mounting system 10.

[0015] As shown in FIG. 3 , the storage unit 43 stores production plan information 44, including one or more mounting jobs 45, used when producing each board S as a processing target object, and selection information 46. The management device 14 acquires production plan information 64 created by the supervisory device 60 via a communication line and stores the production plan information 44 in the storage unit 43. A mounting job 45 is set for each board S as a product to be produced. This mounting job 45 includes information such as the mounting position of feeders 25 holding components P, information on the type and number of components P to be mounted on a specific board S, and the order and position in which the components P are to be mounted on the board S. The mounting device 15 includes individual setups and common setups as the mounting positions of the feeders 25 for each mounting device. The individual setup is a setup in which feeders 25 as supply members are mounted at individual positions for each of the multiple types of boards S produced. The common setup is a setup in which feeders 25 as supply members holding common components P are mounted at a common position for the production of multiple types of boards S. The individual setup allows the feeders 25 to be mounted in unique positions for the production of each board S, thereby further shortening production time. However, it requires the feeders 25 to be unmounted and mounted multiple times during setup changes to switch mounting jobs 45. On the other hand, the common setup mounts the feeders 25 holding the same components P in the same positions across the production of multiple boards S, which may lack flexibility in terms of slot consumption and shortening production time. However, it does not require the feeders 25 to be moved during setup changes to switch mounting jobs 45. The selection information 46 includes a method for retracting the feeders 25 in the common setup and a recovery time for the feeders 25 in the common setup. The retraction method specifies how feeders 25 not required for the production of the board S are retracted from the mounting mounting unit 26 to the standby mounting unit during production execution of the common setup. The recovery time refers to the timing for returning the retracted feeders 25 to the mounting mounting unit 26 and restoring the feeders 25 to their mounting state in the common setup.

[0016] The mounting device 15 is an apparatus that picks up components and mounts them on a board S. The mounting device 15 includes a mounting control unit 20, a board processing unit 22, a component supply unit 24, a mounting unit 30, an imaging unit 34, a nozzle station 35, an operation panel 36, and a communication unit 38. As shown in FIG. 2 , the mounting control unit 20 is configured as a microprocessor centered around a CPU 21 and controls the entire device. The mounting control unit 20 outputs control signals to the board processing unit 22, the component supply unit 24, the mounting unit 30, the imaging unit 34, and the operation panel 36, and inputs signals from the board processing unit 22, the component supply unit 24, the mounting unit 30, the imaging unit 34, and the operation panel 36. The mounting control unit 20 has a memory unit that stores mounting jobs, etc., including information about the components P, the placement order and placement positions for mounting the components P on the board S, and the attachment position of the feeder 25 that picks up the components P. The mounting jobs stored in the memory unit include information similar to the mounting job 45 illustrated in FIG. 3 .

[0017] The substrate processing section 22 carries out the loading, transporting, fixing at the mounting position, and transporting of the substrate S, and also carries out the processing of supporting the substrate S from below using a support member. The substrate processing section 22 has a pair of conveyor belts that are spaced apart from each other at the front and rear of the substrate processing section 22 in Fig. 1 and span across in the left-right direction. The substrate S is transported by these conveyor belts.

[0018] The component supply unit 24 is a unit that supplies components P to the mounting unit 30. The component supply unit 24 has one or more mounting sections that mount feeders 25 as supply members, each of which includes a reel around which a tape is wound as a holding member for holding components. As shown in FIG. 2 , the component supply unit 24 has two mounting sections, one above the other, at the front of the device, to which the feeders 25 can be mounted. The upper section is a mounting mounting section 26 from which the mounting unit 30 can pick up components, and the lower section is a buffer mounting section 27 from which the mounting unit 30 cannot pick up components. Here, the mounting mounting section 26 and the buffer mounting section 27 are collectively referred to as mounting sections. Here, the buffer mounting section 27 and the storage mounting section of the storage device 13 are collectively referred to as a standby mounting section. The component supply unit 24 has a plurality of slots 28 arranged at predetermined intervals in the X direction, into which rail members of the feeders 25 are inserted, and a connection section 29 into which a connector provided at the tip of the feeder 25 is inserted. The feeder 25 is equipped with a controller (not shown). This controller stores information such as the ID of the tape contained in the feeder 25, the component type, and the number of remaining components. When the feeder 25 is connected to the connection unit 29, the controller transmits information about the feeder 25 to the mounting control unit 20.

[0019] The mounting unit 30 is a unit that picks up components P from the component supply unit 24 and places them on a board S fixed to the board processing unit 22. The mounting unit 30 includes a head moving unit 31, a mounting head 32, and a nozzle 33. The head moving unit 31 includes a slider that moves in the X and Y directions along a guide rail, and a motor that drives the slider. The mounting head 32 picks up one or more components and moves it in the X and Y directions by the head moving unit 31. The mounting head 32 is removably attached to the slider. One or more nozzles 33 are removably attached to the underside of the mounting head 32. The nozzles 33 use negative pressure to pick up components. There are multiple types of nozzles 33 that are suited to different types and sizes of components P. There are multiple types of mounting heads 32, and the type and number of nozzles 33 that can be attached to each type are set. The mounting head 32 is configured to be able to mount, for example, one or two nozzles 33 for large components, and four, six, eight, twelve, or sixteen nozzles 33 for general-purpose components. Note that the pickup member for picking up the components may be a mechanical chuck that mechanically holds the components, in addition to the nozzles 33.

[0020] The imaging unit 34 is a camera that captures images of the upper side and captures images of components P held by the mounting head 32. As shown in FIG. 1 , the imaging unit 34 is a device that captures images of one or more components P picked up and held by the mounting head 32. The imaging unit 34 is disposed between the component supply unit 24 and the board processing unit 22. When the mounting head 32 holding the components P passes above the imaging unit 34, the imaging unit 34 captures one or more images and outputs the captured images to the mounting control unit 20. The mounting control unit 20 can confirm the picked-up position and shape of the components P using the images captured by the imaging unit 34. The nozzle station 35 is a storage unit that stores various nozzles 33 used in the mounting unit 30. The operation panel 36 is a unit that accepts input from the operator W and presents information to the operator W. The operation panel 36 is disposed on the front of the mounting device 15 and includes a display unit and an operation unit with a touch panel and buttons. The communication unit 38 is an interface for exchanging information with external devices such as the management device 14 and the control device 60 .

[0021] The automated guided vehicle 17 transports components used in the mounting system 10, such as printing-related components used by the printer 11 and mounting-related components used by the loader 18. The automated guided vehicle 17 automatically transports, for example, printing-related components and mounting-related components between a warehouse (not shown) and the storage device 13. The mounting-related components include, for example, a feeder 25 as a supply device, a support member for the substrate S, and a mounting head 32 and a nozzle 33 as collection members. Note that, here, the automated guided vehicle 17 will be described as mainly transporting the feeder 25. The automated guided vehicle 17 may be an AGV (Automatic Guided Vehicle) that travels along a predetermined path, or an AMR (Autonomous Mobile Robot) that senses its surroundings and travels to its destination along a free route.

[0022] The loader 18 is a mobile work device that moves within a movement area in front of the mounting system 10 and automatically collects and replenishes the feeders 25 of the mounting device 15. The loader 18 includes a movement control unit 50, a memory unit 52, a storage unit 53, an exchange unit 54, a movement unit 55, and a communication unit 58. The movement control unit 50 is configured as a microprocessor centered on a CPU 51 and controls the entire device. The memory unit 52 stores various data such as processing programs, including information related to the replacement work. The storage unit 53 has a storage space for storing the feeders 25. The storage unit 53 is configured to be able to store, for example, four feeders 25. The exchange unit 54 is a mechanism for inserting and removing the feeders 25 and for moving them between upper and lower levels (see FIG. 2). The replacement unit 54 includes a clamping unit that clamps the feeder 25, a Y-axis slider that moves the clamping unit in the Y-axis direction (front-back), and a Z-axis slider that moves the clamping unit in the Z-axis direction (up-down). The replacement unit 54 performs the attachment and detachment of the feeder 25 in the mounting mounting unit 26 and the attachment and detachment of the feeder 25 in the buffer mounting unit 27. The movement unit 55 is a mechanism that moves the loader 18 in the X-axis direction (left-right) along the X-axis rail 39 disposed in front of the mounting device 15. The communication unit 58 is an interface that exchanges information with external devices such as the management device 14 and the mounting device 15. The loader 18 outputs its current position and the details of the work it has performed to the management device 14. The loader 18 is capable of automatically attaching and detaching the feeder 25 as a supply member, but may also be configured to collect and replenish mounting-related materials, printing-related materials, and the like.

[0023] The supervisory device 60 (see FIG. 1 ) is configured as a server that manages information about each device in the mounting system 10. The supervisory device 60 includes a supervisory control unit 61 that controls the entire device, a storage unit 63 that stores various information, and a communication unit 68 that performs two-way communication with external devices such as the mounting system 10, the automated guided vehicle 17, and the loader 18. The supervisory device 60 creates and manages production plan information 64 used in the component mounting process and mounting jobs 65 included in the production plan information 64, as well as acquires and manages information about the mounting system 10.

[0024] Next, the operation of the mounting system 10 of this embodiment configured as described above will be described. First, the process in which the supervisory device 60 creates production plan information 64 will be described. When this process begins, the CPU 62 of the supervisory control unit 61 first acquires information on all of the boards S, which are the processing targets to be manufactured under the current production plan. For example, the CPU 62 acquires the type of component P and the number of components from the data on the boards S, which are the products, and acquires the number of modules and mounting units of the mounting devices 15 from the configuration of the mounting system 10. Next, the CPU 62 sets a mounting job 65 for each board S to be produced. The CPU 62 also sets a common setup including multiple mounting jobs 65 and individual setups based on information selected in advance by the worker W. For example, as shown in FIG. 3 , the CPU 62 creates production plan information 64 including a common setup including mounting jobs A to E, a common setup including mounting jobs F to J, and an individual setup including mounting job K. The supervisory device 60 outputs the created production plan information 64 to the management device 14 on the production line that executes the production process.

[0025] Next, the process in which the mounting device 15 mounts components P on the board S using the production plan information 44 will be described. Here, the individual setup mounting process will be mainly described. When the mounting process begins, the CPU 21 of the mounting control unit 20 acquires a mounting job 45 for the product to be manufactured from the management device 14. The CPU 21 may acquire the mounting job 45 for its own machine for each product from the management device 14 or from the supervisory device 60. The loader 18 also executes a setup change process to mount each feeder 25 at the mounting position set in the mounting job 45. When production can begin, the CPU 21 controls the board processing unit 22 to load and secure the board S. Next, based on the mounting job 45, the CPU 21 causes the mounting head 32 to pick up components P from the feeders 25 mounted in the component supply unit 24 and place them on the board S. After the components P have been placed on the board S, the CPU 21 ejects the board S to the board processing unit 22 and repeats the above-described process. During this mounting process, the CPU 21 manages the number of components consumed by each feeder 25, and when the number of remaining components falls below a predetermined warning value, it sends replacement information to that effect to the management device 14. Based on this replacement information, the management device 14 causes the loader 18 to perform the feeder 25 replacement work. The loader 18 moves along the X-axis rail 39 between the storage device 13 and the mounting device 15, and performs the feeder 25 replacement process at the target mounting device 15. Then, when the production of the current board S is completed, it determines whether the next board S is to be produced, and if so, causes the loader 18 to perform the setup process. The loader 18 performs the process of mounting each feeder 25 at the mounting position for the next production job 65.

[0026] Next, the setting of execution conditions for the changeover process in the common setup performed by the mounting device 15 will be described. FIG. 4 is a flowchart showing an example of an execution condition setting processing routine executed by the management control unit 41 of the management device 14. This routine is stored in the memory unit 43 of the management device 14 and is executed based on input from the worker W before starting production processing of the board S. When this routine is started, the CPU 42 of the management control unit 41 first outputs an execution condition setting screen to acquire execution conditions for the changeover process in the common setup (S100). The management device 14 outputs and displays an execution condition input screen 80 on the display unit 49.

[0027] FIG. 5 is an explanatory diagram showing an example of an execution condition input screen 80 displayed on the display unit 49. The execution condition input screen 80 includes a cursor 81, a selection process display field 82, a selection input field 83, a summary display field 84, a message display field 86, a back key 88, and a confirmation key 89. The cursor 81 is configured to be movable by the operator W's operation so that the operator W can select an input position. The selection process display field 82 is a field that displays the selection process of the execution conditions of the common setup. The selection input field 83 is a field for inputting which one to select. The summary display field 84 is a field that displays a summary of the options. The message display field 86 is a field that displays a message to the operator W. The back key 88 is a key for returning the display screen of the display unit 49 to the previous screen. The confirmation key 89 is a key for confirming the selection of the selection process. The selection process of the execution conditions includes the method for retracting the feeder 25 of the common setup and the recovery time of the feeder 25. The options for the evacuation method include evacuation of all unnecessary feeders 25 of the common setup to the buffer mounting unit 27, evacuation of the number of feeders 25 required to replenish out-of-components to the buffer mounting unit 27, and evacuation of a feeder 25 to the buffer mounting unit 27 when it runs out of components. Options for the recovery time include, for example, when the last mounting job in the common setup is completed, when the common setup is completed and switching to the next mounting job, and when a predetermined number of times has passed just before the end of the common setup. Options for when a predetermined number of times has passed include, for example, a predetermined number of times before the end of the last mounting job in the common setup and a predetermined time before the end of the last mounting job in the common setup. The operator W can select an option for the evacuation method and an option for the recovery time and confirm the input contents by pressing the confirmation key 89.

[0028] After S100, the CPU 42 determines whether the input of the execution conditions has been confirmed (S110), and if the input has not been confirmed, the CPU 42 waits. On the other hand, if the input of the execution conditions has been confirmed, the CPU 42 stores the selected content entered and confirmed on the execution condition input screen 80 as selection information 46 including the execution conditions in the storage unit 43 (S120), and ends this routine. In this way, the management device 14 sets the execution conditions for the common setup in advance, such as before the start of the implementation process.

[0029] Next, a process in which the management device 14 issues a command to the loader 18 while the mounting device 15 is performing a mounting process will be described. FIG. 6 is a flowchart illustrating an example of a mounting management process routine executed by the management control unit 41 of the management device 14. This routine is stored in the memory unit 43 of the management device 14 and is executed based on input from the operator W when starting production processing of the board S. Furthermore, upon starting this routine, for example, when production starts with a mounting job 45 of a common setup, the operator W uses a feeder magazine changer, which arranges the feeders 25 in the mounting positions specified in the common setup, to load the feeders into the component supply unit 24 of the corresponding mounting device 15 in a batch loading manner (see FIG. 7A , described later). The feeder magazine changer is a cart equipped with slots 28 similar to those of the mounting unit 26. When the feeder magazine changer is brought close to and facing the component supply unit 24, the feeders in the slots can be loaded into the mounting unit 26 of the component supply unit 24 in a batch loading manner. Furthermore, the feeder magazine changer is configured so that when it is brought close to the mounting mounting section 26 to which a group of feeders is attached in an empty slot state, it can collectively unmount the group of feeders. In this way, using the feeder magazine changer in the mounting system 10 can shorten the setup time. After mounting the feeders 25, the worker W starts the mounting process of the mounting device 15 and also starts this routine.

[0030] When this routine starts, the CPU 42 of the management control unit 41 first reads and acquires the production plan information 44 and selection information 46 from the CPU 42 (S200), and sets the mounting job 45 currently being executed by the mounting device 15 as the mounting job 45 to be managed and executed (S210). For example, in the example of FIG. 3, the CPU 42 first sets mounting job A as the execution job based on the order set in the production plan information 44 in the common setup. Note that the examples shown in FIGS. 3 and 7 and 8 will be described here as specific examples. FIGS. 7 and 8 are explanatory diagrams showing an example of the process of executing a mounting job in the common setup. In FIGS. 7 and 8, the number of the mounting job to be used, among mounting jobs A to E and F to J, is shown in the feeder 25. 7A is a diagram showing the installation state of common setup 1, Fig. 7B is a diagram showing unused feeders 25 being retracted to the buffer installation section 27 when mounting job A is being executed, Fig. 7C is a diagram showing the interchange of used and unused feeders 25 when mounting job B is being executed, and Fig. 7D is a diagram showing the interchange of used and unused feeders 25 when mounting job C. Also, in Fig. 8A is a diagram showing the interchange of used and unused feeders 25 when mounting job D is being executed, Fig. 8B is a diagram showing the interchange of used and unused feeders 25 when mounting job E is being executed, Fig. 8C is a diagram showing the restored installation state of common setup 1, and Fig. 8D is a diagram showing the installation state of common setup 2.

[0031] After S210, the CPU 42 outputs a command to the loader 18 to move feeders 25 not being used in the currently executing mounting job to the standby mounting unit (S220). The CPU 42 sets this evacuation command based on the execution conditions set in the selection information 46. In the mounting device 15, if there is an empty slot in the mounting mounting unit 26, this empty slot can be used to replace a feeder when a component runs out, thereby enabling efficient feeder replacement. The mounting device 15 can also determine the timing of component outages from the empirical cycle time of the mounting process when setting the production plan information 44, and can also calculate the minimum number of empty slots required for feeder replacement. For this reason, the selection information 46 also specifies as an option the evacuation of the number of feeders required for replenishment, as shown in FIG. 5. Upon receiving this evacuation command, the loader 18 moves the unused feeders 25 to the buffer mounting unit 27, which serves as the standby mounting unit, based on the evacuation command (FIGS. 7A and 7B). When there is no available slot in the buffer mounting unit 27 of the corresponding mounting device 15, the loader 18 may evacuate the unused feeder 25 to the buffer mounting unit 27 of a nearby mounting device 15. When there is no available slot in the nearby buffer mounting unit 27, the loader 18 may evacuate the unused feeder 25 to the storage mounting unit of the storage device 13.

[0032] Next, the CPU 42 determines whether there is a feeder 25 that needs to be replaced (S230). The CPU 42 determines whether there is a feeder 25 that needs to be replaced based on the number of components used, the number of components remaining, etc. If there is a feeder that needs to be replaced, the CPU 42 outputs an exchange command for the corresponding feeder 25 to the loader 18 (S240). The loader 18, which has received this exchange command, executes a process of exchanging the feeder 25 that is to be replaced with a new feeder 25 based on the exchange command. The new feeder 25 may be located in an empty slot of the mounting mounting unit 26, the buffer mounting unit 27, the storage mounting unit of the storage device 13, etc.

[0033] After S240, or if there is no feeder 25 requiring replacement in S230, the CPU 42 determines whether the currently executing mounting job is an individual setup or a common setup (S250). If the currently executing mounting job is an individual setup, the CPU 42 determines whether to continue or end the current mounting job (S260). If the current mounting job is to be continued, i.e., if the production of the currently executing board S has not yet been completed, the CPU 42 executes the processing from S230 onwards. On the other hand, if the current mounting job is to be completed, i.e., if the production of the board S in this mounting job has been completed, the CPU 42 switches to the next mounting job and outputs a setup change command to the loader 18 to execute a setup change (S270). In the individual setup, the loader 18, upon receiving this setup change command, executes the replacement work of the feeder 25 attached to the mounting attachment unit 26 based on the setup change command.

[0034] On the other hand, if the currently executing mounting job is a common setup in S250, the CPU 42 determines whether the current time has reached a predetermined timing for the end of the common setup (S280). The CPU 42 can use the "feeder recovery time for common setup" set in the selection information 46 to determine whether the predetermined timing has arrived. The CPU 42 may use one or more of the following as the predetermined timing: the timing at the end of the last mounting job in the common setup; the timing after the common setup is completed and before the execution of the mounting job for the next production; the timing a predetermined number of times before the end of the last mounting job in the common setup; or the timing a predetermined time before the end of the last mounting job in the common setup. Note that the "predetermined number of times before" and "predetermined time before" can be empirically determined based on the number of boards and the time required to restore the feeder 25 to the mounting state specified in the common setup, and can be set to values ​​with a margin added as necessary. The CPU 42 may also monitor the file name of the currently executing mounting job and determine the timing at the end of the last mounting job in the common setup based on changes to the file name. This file name may be, for example, the file name of the mounting job or the file name of the common setup.

[0035] If it is not yet time in S280 for the predetermined timing for the end of the common setup, the CPU 42 determines whether to end the current mounting job, i.e., whether the production of the currently running board S has been completed (S330). If the current mounting job is not to be ended, the CPU 42 executes the processing from S230 onward. That is, the CPU 42 determines whether the currently running mounting job will be ended while determining whether the predetermined timing has been reached. On the other hand, when the current mounting job is ended in S330, i.e., when the production of the currently running board S has been completed, or after S270, the CPU 42 determines whether all mounting jobs have been completed, i.e., whether all production according to the production plan information 44 has been completed (S340). If all mounting jobs have not been completed, the CPU 42 executes the processing from S210 onward. That is, the CPU 42 continues to execute the production of boards S according to the production plan information 44.

[0036] On the other hand, if the current time has reached a predetermined timing for the end of the common setup, the CPU 42 determines whether the current time has arrived for a changeover (S290). If the current time has arrived for a changeover, the CPU 42 outputs information to the operator W indicating that the feeders 25 will be replaced all at once (S300). The CPU 42 may also display a message to that effect on the display unit 49. After confirming this information, the operator W performs a batch replacement of the feeders 25, for example, using a feeder magazine changer. After S300, or if the current time for a changeover has not arrived in S290, the CPU 42 determines whether there are any feeders 25 with different mounting positions in the common setup mounting state of the mounting mounting unit 26 (S310). For example, if there are any feeders 25 that have been retracted to the standby mounting unit, the CPU 42 determines that there are feeders 25 with different mounting positions. If there is a feeder 25 with a different mounting position, the CPU 42 outputs a command to restore the mounting position of the corresponding feeder 25 to the loader 18 (S320). The loader 18, which has received this command, executes the operation of moving the feeder 25 with the different mounting position to the mounting position of the common setup.

[0037] After S320, or when the predetermined timing for completing the common setup has not yet been reached in S280, or when there are no feeders 25 with different mounting positions in S310, the CPU 42 executes the processes from S330 onwards. Then, when all mounting jobs have been completed in S340, the CPU 42 outputs a command to the loader 18 to collect the feeders 25 mounted in the mounting mounting unit 26 (S350), and ends this routine. Upon receiving this command, the loader 18 moves the feeders 25 mounted in the mounting mounting unit 26 to the standby mounting unit as necessary.

[0038] For example, as shown in Fig. 7B , the CPU 21 of the mounting device 15 executes mounting job A, and when production of the board S is completed, the loader 18 replaces the feeders 25, and the CPU 21 executes mounting job B, as shown in Fig. 7C . Furthermore, when production of the board S of mounting job B is completed, the loader 18 replaces the feeders 25, and the CPU 21 executes mounting job C, as shown in Fig. 7D . Furthermore, when the CPU 21 executes mounting job C and production of the board S is completed, the loader 18 replaces the feeders 25, and the CPU 21 executes mounting job D, as shown in Fig. 8A . Furthermore, when mounting job D is executed and production of the board S is completed, the feeders 25 are replaced, and the CPU 21 executes mounting job E, as shown in Fig. 8B . Then, when mounting job E, the last mounting job of the common setup, is completed, the loader 18 executes recovery processing to restore the feeders 25 to the installation state in the common setup, as shown in Fig. 8C . When the mounting process using the common setup is completed, the CPU 42 notifies the worker W of the batch replacement of the feeders 25, and the worker W, upon confirming this, performs batch replacement of the group of feeders in the common setup 2. In the mounting device 15, if an empty slot is provided in the mounting attachment section 26, the position of the feeders 25 changes, making batch replacement using a feeder magazine changer or the like impossible. In this mounting device 15, the arrangement state of the feeders 25 in the common setup is restored at a predetermined timing in the mounting process using the common setup, making batch replacement of the feeders 25 possible.

[0039] Here, the correspondence between the components of this embodiment and the components of the present disclosure will be clarified. The mounting system 10 of this embodiment corresponds to an example of a mounting system, the mounting device 15 corresponds to a mounting device, the loader 18 corresponds to a mobile work device, and the management device 14 corresponds to a management device. Also, the management control unit 41 corresponds to an example of a management control unit, the mounting mounting unit 26 corresponds to an example of a mounting mounting unit, the buffer mounting unit 27 and the storage mounting unit of the storage device 13 correspond to an example of a standby mounting unit, and the CPU 51 corresponds to an example of a mobile control unit.

[0040] The management device 14 described above is used in a mounting system 10 including a mounting device 15 having a mounting unit 30 that mounts components P on a substrate S as a processing target, a component supply unit 24 that serves as a supply unit having a mounting mounting unit 26 that mounts feeders 25 holding the components P and supplies the components P, and a mounting control unit 20 that causes the mounting unit 30 to pick up the components P from the component supply unit 24, and a loader 18 that serves as a mobile work device that automatically exchanges feeders 25 between a standby mounting unit that is not capable of mounting and the mounting mounting unit 26. This management device 14 includes a management control unit 41 that outputs a recovery command to loader 18 to move feeders 25 included in the common setup that are not in mounting mounting unit 26 to mounting positions of the common setup at a predetermined timing when production of the substrates S using this common setup is completed after feeders 25 using a common setup that mounts feeders 25 holding common components P at positions common to the mounting mounting unit 26 are mounted on the mounting mounting unit 26. With this management device 14, the arrangement of the feeders 25 in the common setup is restored when production using the common setup is completed, making it possible to replace the feeders 25 all at once, thereby reducing internal setup time and achieving greater efficiency.

[0041] The loader 18 also moves some or all of the feeders 25 included in multiple types of common setups that are not required for the current production of the board S to the standby mounting section. In this management device 14, by moving feeders 25 not required for the current production from the mounting mounting section 26, an empty slot is created in the mounting mounting section 26, facilitating feeder 25 replacement and enabling more efficient mounting processing. Furthermore, the management control unit 41 outputs a recovery command at a predetermined timing: a predetermined number of times or a predetermined time before the end of the last mounting job 45 in the common setup, at the end of the last mounting job 45 in the common setup, or after the end of the common setup and before the execution of the mounting job 45 for the next production. In this management device 14, for example, if the predetermined timing is set to before the end of a mounting job 45, the common setup is restored in advance, allowing the feeders 25 to be replaced all at once immediately after production using the common setup is completed, thereby improving efficiency. Furthermore, if the predetermined timing is set to the end of a mounting job 45, production using the common setup is reliably performed and waiting time is reduced, improving efficiency. Furthermore, if the predetermined timing is set to be before the execution of the mounting job 45 of the next production, the feeders 25 can be replaced all at once after production using a common setup has been more reliably carried out.

[0042] The management control unit 41 also monitors the name of the file currently being executed for the mounting job 45 and outputs a recovery command when the file name is changed. The management device 14 can achieve greater efficiency by switching the file name of the mounting job 45. Furthermore, in the management device 14, the standby mounting unit includes the buffer mounting unit 27 of the mounting device 15 from which the mounting unit 30 cannot pick up components P, and a storage mounting unit provided in the storage device 13 that stores the feeders 25. The management device 14 can evacuate the feeders to the buffer mounting unit 27 or the storage mounting unit. Furthermore, after outputting the recovery command, the management device 14 notifies the worker W of information indicating that the feeders included in the common setup will be replaced all at once. The management device 14 allows the worker W to replace the feeders included in the common setup all at once.

[0043] Furthermore, the loader 18 as a mobile working device is used in a mounting system 10 including a mounting device 15 having a mounting unit 30 that mounts components P on a substrate S as a processing target, a component supply unit 24 that serves as a supply unit having a mounting mounting unit 26 that mounts feeders 25 holding the components P and supplies the components P, and a mounting control unit 20 that causes the mounting unit 30 to pick up the components P from the component supply unit 24. The loader 18 also includes an exchange unit 54 that automatically exchanges the feeders 25 between a standby mounting unit that is not capable of mounting and the mounting mounting unit 26, and a movement control unit 50 that causes the exchange unit 54 to execute a recovery process to move feeders 25 included in the common setup that are not in the mounting mounting unit 26 to mounting positions of the common setup at a predetermined timing when production of the substrates S using this common setup is completed after feeders 25 based on a common setup that mounts feeders 25 holding components common to positions common to the production of multiple types of substrates S are mounted on the mounting mounting unit 26. With this loader 18, the feeder arrangement of the common setup can be restored when production using the common setup is completed, so all feeders 25 can be replaced at once, which reduces internal setup time and improves efficiency.

[0044] In this loader 18, the movement control unit 50 moves some or all of the feeders 25 included in multiple types of common setups that are not required for the current production of the board S to the standby mounting unit. In this loader 18, by moving the feeders 25 not required for the current production from the mounting mounting unit 26, the mounting mounting unit 26 becomes available, facilitating feeder 25 replacement and enabling more efficient mounting processing. The movement control unit 50 also executes recovery processing at a predetermined timing: a predetermined number of times or a predetermined time before the end of the last mounting job 45 in the common setup, at the end of the last mounting job 45 in the common setup, or after the end of the common setup and before the execution of the mounting job 45 for the next production. In this loader 18, for example, if the predetermined timing is set to be before the end of a mounting job 45, the common setup is restored in advance, allowing the feeders 25 to be replaced all at once immediately after production using the common setup is completed, thereby improving efficiency. If the predetermined timing is set to be the end of a mounting job 45, production using the common setup can be reliably performed and waiting time can be reduced, improving efficiency. Furthermore, if the specified timing is set to be before the execution of the mounting job for the next production, it is possible to more reliably perform production using the common setup and then replace the feeders 25 all at once. Furthermore, in the loader 18, the standby mounting section includes a buffer mounting section 27 of the mounting device 15 from which the mounting section 30 cannot pick up components P, and / or a storage mounting section provided in the storage device 13 that stores the feeders 25. In this loader 18, the feeders 25 can be retracted to the buffer mounting section 27 or the storage mounting section.

[0045] The mounting system 10 also includes a mounting device 15 having a mounting unit 30 that mounts components P on a substrate S as a processing target, a component supply unit 24 that serves as a supply unit having a mounting mounting unit 26 that mounts feeders 25 holding the components P and that supplies the components P, and a mounting control unit 20 that causes the mounting unit 30 to pick up the components P from the component supply unit 24, the management device 14 described above, and the loader 18 described above. Because the mounting system 10 includes the management device 14 described above and the loader 18 described above, when production using the common setup is completed, greater efficiency can be achieved by restoring the feeder arrangement of the common setup.

[0046] It goes without saying that the present disclosure is not limited to the above-described embodiments, and can be embodied in various forms as long as they fall within the technical scope of the present invention.

[0047] For example, in the above-described embodiment, the recovery command is output at a predetermined timing, either a predetermined number of times or a predetermined time before the end of the last mounting job 45 in the common setup, at the end of the last mounting job 45 in the common setup, or after the end of the common setup and before the execution of the mounting job 45 for the next production, but this is not particularly limited. The predetermined timing may be omitted from any of these four types, or a timing other than these four types may be added. Furthermore, for example, the management control unit 41 may determine whether it is time to retrieve the feeder 25 placed in the supply unit each time a mounting job is completed, and output a recovery command if it is determined that it is time to retrieve the feeder 25.

[0048] In the above-described embodiment, the CPU 42 monitors the file name of the mounting job being executed and outputs a recovery command when the file name is changed, but this is not particularly limited. The CPU 42 may also monitor something other than a change in the file name.
