Description

[Technical field]

[0001] This specification discloses a component mounting system. [Background technology]

[0002] Conventionally, a component mounting system has been proposed that includes a component mounting line including multiple component mounters arranged in a board transport direction, a feeder storehouse that stores multiple feeders that are installed in the component mounting line and can be attached to each component mounter, an automated guided vehicle (AGV), and an exchange robot (see, for example, Patent Document 1). Each component mounter has a supply area and a stock area to which the feeder can be attached and detached. The supply area is configured as an area where the feeder can supply components. The stock area is configured as an area where the feeder can be stocked. The feeder storehouse has a storage area where the feeder can be attached and detached at the same height as the supply area of ​​each component mounter. The AGV carries the feeder in and out from the outside of the component mounting line to the storage area of ​​the feeder storehouse. The exchange robot removes a feeder that contains components required for the next mounting process from the storage area of ​​the feeder storehouse and attaches it to the supply area of ​​each component mounter, or removes a feeder that contains components not required for the next mounting process from the supply area and attaches it to the stock area or storage area.

[0003] [Patent Document 1] International Publication No. 2017 / 033268 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned component mounting system, the exchange robot needs to exchange feeders between the storage area of ​​the feeder storehouse and each supply area or each stock area of ​​the multiple component mounting machines, and between the supply areas and the stock areas. Therefore, when changing the setup, it takes a long time to exchange all the feeders, which may delay the start of production and reduce production efficiency.

[0005] A primary object of the present disclosure is to improve production efficiency by efficiently replacing feeders. [Means for solving the problem]

FIG. 4 is a schematic diagram of a loader. FIG. 5 is a schematic diagram of a component mounter and an AGV. FIG. 6 is a schematic diagram of an AGV. FIG. 7 is a block diagram showing the electrical connection relationship of the component mounting system. In FIG. 1, FIG. 2 and FIG. 5, the left-right direction is the X-axis direction, the front-back direction is the Y-axis direction, and the up-down direction is the Z-axis direction.

[0012] The component mounting system 10 produces a mounted board by mounting components on a board S on which solder has been printed, and as shown in FIG. 1, includes a printing device 12, a print inspection device 14, a plurality of component mounters 20, a mounting inspection device (not shown), a loader 50, an AGV 60, and a management device 80 that manages the entire system. The printing device 12 prints solder on the surface of the board S. The print inspection device 14 inspects the state of the solder printed by the printing device 12. The component mounter 20 picks up components supplied from a feeder 30 with a suction nozzle (picking member) and mounts them on the board S. The mounting inspection device inspects the mounting state of the components mounted by the component mounter 20. The printing device 12, the print inspection device 14, the component mounters 20, and the mounting inspection device are aligned in this order from upstream along the transport direction of the board S to form a production line.

[0013] 2, the component mounter 20 includes a board transport device 22 that transports the board S in the X-axis direction, a head 25, a head moving device 24 that moves the head 25 in the horizontal direction (XY-axis direction), and a mounting control device 29 (see FIG. 7). Although not shown, the head 25 has a suction nozzle that picks up components, and a lifting device that raises and lowers the suction nozzle using a ball screw mechanism, a motor, or the like. The head moving device 24 has a slider 24a to which the head 25 is attached, and a motor (not shown) that moves the slider 24a in the horizontal direction (XY-axis direction) via a ball screw mechanism or the like.

[0014] In addition, the component mounter 20 also includes a mark camera 26 and a parts camera 27. The mark camera 26 captures an image of a reference mark attached to the board S from above in order to detect the position of the board S. The parts camera 27 captures an image of a component picked up by the suction nozzle from below in order to detect suction errors and suction deviations.

[0015] The mounting control device 29 is composed of a known CPU 29a, ROM 29b, HDD 29c, RAM 29d, etc. The mounting control device 29 inputs image signals and the like from the mark camera 26 and the parts camera 27. In addition, the mounting control device 29 outputs drive signals to the board transport device 22, the head 25, the head moving device 24, etc.

[0016] When performing a mounting process for mounting components on the board S, the CPU 29a of the mounting control device 29 controls the head moving device 24 so that the head 25 moves above the components supplied from the feeder 30. Next, the CPU 29a controls the head 25 so that the suction nozzle is lowered by the lifting device so that the components are picked up by the suction nozzle. The CPU 29a controls the head moving device 24 so that the components picked up by the suction nozzle move above the parts camera 27, and the parts camera 27 takes an image of the components. The CPU 29a processes the captured image of the components to measure the amount of suction displacement of the components, and corrects the mounting position of the components on the board S based on the measured amount of suction displacement. Then, the CPU 29a controls the head moving device 24 so that the components picked up by the nozzle move above the corrected mounting position, and controls the head 25 so that the suction nozzle is lowered by the lifting device so that the components are mounted on the board S.

[0017] As shown in FIG. 3, the feeder 30 is a rectangular cassette-type tape feeder, and is detachably held on a feeder table 40. The feeder 30 includes a tape reel 32, a tape feed mechanism 33, a connector 35, a rail member 37, and a feeder control device 39 (see FIG. 7). The tape reel 32 has a tape 31 wound thereon. The tape 31 has cavities formed at predetermined intervals along its longitudinal direction. Each cavity contains a component. These components are protected by a film covering the surface of the tape 31. The tape feed mechanism 33 pulls out the tape 31 from the tape reel 32 and feeds it to the component supply position. The components contained in the tape 31 are exposed at the component supply position by peeling off the film just before the component supply position, and are sucked by the head 25 (suction nozzle). The connector 35 has two positioning pins 34 on both sides thereof that protrude in the mounting direction. Rail member 37 is provided at the lower end of feeder 30 and extends in the mounting direction. Feeder control device 39 is composed of a known CPU, ROM, RAM, etc., and outputs a drive signal to tape feed mechanism 33 (feed motor). In addition, feeder control device 39 is capable of communicating with a control unit (such as mounting control device 29) of the attachment destination of feeder 30 via connector 35.

[0018] As shown in FIG. 2, the component mounter 20 has two areas, an upper area and an lower area, in the front where the feeder 30 can be set. The upper area is a supply area 20A where the feeder 30 can supply components to a component supply position, and the lower area is a stock area 20B for stocking the feeder 30. Each of the areas 20A and 20B is provided with a feeder table 40 to which a plurality of feeders 30 can be attached and detached. As shown in FIG. 2, the feeder table 40 is an L-shaped table in a side view, and has a slot 42, two positioning holes 44, and a connector 45. The rail member 37 of the feeder 30 is inserted into the slot 42. The two positioning pins 34 of the feeder 30 are inserted into the two positioning holes 44, and the feeder 30 is positioned on the feeder table 40. The connector 45 is provided between the two positioning holes 44 and is connected to the connector 35 of the feeder 30.

[0019] FIG. 8 is an explanatory diagram showing an example of the supply area information and the stock area information stored in the HDD 29c. The supply area information is information on the feeder 30 set in the supply area 20A. The stock area information is information on the feeder 30 set in the stock area 20B. The supply area information includes, as feeder information, position information (slot number) of the attachment position of the feeder 30 in the supply area 20A, ID information of the feeder 30, information on the type of components stored in the feeder 30, information on the number of remaining components, and the like. These pieces of information are stored in the HDD 29c in association with each other. The position information is determined in order with the reference slot (for example, the leftmost slot 42) of the multiple slots 42 of the feeder table 40 as the leading position "001". The stock area information includes, as feeder information, position information (slot number) of the attachment position of the feeder 30 in the stock area 20B, ID information of the feeder 30, information on the type of components stored in the feeder 30, information on the number of remaining components, and the like. These pieces of information are stored in the HDD 29c in association with each other. The supply area information and the stock area information are acquired by the mounting control device 29 of the component mounter 20 from the feeder control device 39 of the feeder 30 when the feeder 30 is attached or detached or when components are supplied during component mounting processing, and are updated as appropriate. Note that in Fig. 8, the position information "003" in the stock area information indicates that the feeder 30 is not attached to the position.

[0020] The loader 50 moves along a guide rail 18 provided in front of a plurality of component mounters 20 in parallel to the board transport direction (X-axis direction) as shown in Fig. 1. The loader 50 includes a loader moving device 51 and a feeder transfer device 53 as shown in Fig. 4, and also includes a position sensor 57, a monitoring sensor 58, and a loader control device 59 as shown in Fig. 5. The loader moving device 51 includes an X-axis motor 52a that drives a drive belt for moving the loader 50 in the X-axis direction, and a guide roller 52b that rolls on the guide rail 18 to guide the movement of the loader 50.

[0021] The feeder transfer device 53 transfers the feeder 30 between the supply area 20A and the stock area 20B of the component mounter 20 at a position where the loader 50 faces the feeder table 40 of the component mounter 20. The feeder transfer device 53 has a Y-axis slider 55 and a Z-axis motor 56a that moves the Y-axis slider 55 along the Z-axis guide rail 56b. The Y-axis slider 55 includes a clamp unit 54 that clamps the feeder 30 and a Y-axis motor 55a that moves the clamp unit 54 along the Y-axis guide rail 55b. The Y-axis slider 55 moves to a position facing the supply area 20A of the component mounter 20 and a position facing the stock area 20B by driving the Z-axis motor 56a.

[0022] The position sensor 57 is an encoder that detects the movement position in the left-right direction (X-axis direction) of the loader 50. The monitoring sensor 58 monitors the presence or absence of an obstacle (worker) in the left-right direction (X-axis direction) of the loader 50, and is configured as, for example, a laser scanner.

[0023] The loader control device 59 is composed of a known CPU, ROM, RAM, etc., and receives detection signals from the position sensor 57 and monitoring sensor 58, and outputs drive signals to the loader moving device 51 and the feeder transfer device 53.

[0024] When the loader control device 59 transfers the feeder 30 from the stock area 20B (transfer source) to the supply area 20A (transfer destination), first, the loader control device 59 controls the Z-axis motor 56a so that the Y-axis slider 55 moves downward to a position facing the stock area 20B. Next, the loader control device 59 controls the Y-axis motor 55a so that the clamp unit 54 moves in a direction approaching the feeder table 40 of the stock area 20B, and the feeder 30 attached to the feeder table 40 is clamped by the clamp unit 54. Then, the loader control device 59 controls the Y-axis motor 55a so that the clamp unit 54 moves in a direction away from the feeder table 40 (forward in FIG. 4). As a result, the feeder 30 is removed from the feeder table 40 of the stock area 20B and collected into the loader 50. Next, the loader control device 59 controls the Z-axis motor 56a so that the Y-axis slider 55 moves upward to a position facing the supply area 20A. Next, the loader control device 59 controls the Y-axis motor 55a so that the clamp unit 54, which has clamped the feeder 30, moves in a direction approaching the feeder table 40 in the supply area 20A (rearward in FIG. 4), and releases the clamp of the clamp unit 54. As a result, the feeder 30 is attached to the feeder table 40 with its rail member 37 inserted into the slot 42 of the feeder table 40 in the supply area 20A.

[0025] In addition, when the loader control device 59 transfers the feeder 30 from the supply area 20A (transfer source) to the stock area 20B (transfer destination), first, the loader control device 59 controls the Z-axis motor 56a so that the Y-axis slider 55 moves upward to a position facing the supply area 20A. Next, the loader control device 59 controls the Y-axis motor 55a so that the clamp unit 54 moves in a direction approaching the feeder table 40 of the supply area 20A, and the feeder 30 attached to the feeder table 40 is clamped by the clamp unit 54. Then, the loader control device 59 controls the Y-axis motor 55a so that the clamp unit 54 moves in a direction away from the feeder table 40 (forward in FIG. 4). As a result, the feeder 30 is removed from the feeder table 40 of the supply area 20A and collected into the loader 50. Next, the loader control device 59 controls the Z-axis motor 56a so that the Y-axis slider 55 moves downward to a position facing the stock area 20B. Next, the loader control device 59 controls the Y-axis motor 56a so that the clamp unit 54, which has clamped the feeder 30, moves in a direction approaching the feeder table 40 in the stock area 20B (rearward in FIG. 4), and releases the clamp of the clamp unit 54. As a result, the feeder 30 is attached to the feeder table 40 with its rail member 37 inserted into the slot 42 of the feeder table 40 in the stock area 20B.

[0026] When a changeover or transfer of a feeder 30 that has run out of components is instructed with the designation of the component mounter 20 and the designation of the source and destination of the feeder 30, the loader control device 59 controls the loader movement device 51 so that the loader 50 moves (travels) to a target position facing the designated component mounter 20. When the loader 50 arrives at the target position, as described above, the loader control device 59 controls the loader 50 to remove the feeder 30 from the source and attach the removed feeder 30 to the destination. If an obstacle is detected by the monitoring sensor 58 while the loader 50 is traveling, the loader control device 59 stops the loader 50 from traveling until the obstacle is no longer detected.

[0027] The AGV 60 is configured as an automatic conveying device (for example, a floor-traveling automatic conveying device) and moves between a warehouse (not shown) storing a large number of feeders 30 and each component mounter 20. As shown in FIG. 5, the AGV 60 conveys a feeder table 40 (pallet) on which the feeders 30 are attached, and collects used feeders 30 together with the feeder table 40 (pallet) from the stock area 20B, and supplies feeders 30 to be used together with the feeder table 40 (pallet) to the stock area 20B. In this embodiment, a plurality of AGVs 60 are arranged, and one AGV 60 collects the feeder table 40 on which the used feeders 30 are attached from the stock area 20B, and the other AGV 60 supplies the feeder table 40 on which the feeders 30 to be used are attached to the stock area 20B. The AGV 60 may be configured to be capable of collecting and supplying the feeder table 40 by one unit.

[0028] As shown in FIG. 7, the AGV 60 includes an AGV moving device 61, a pallet transfer device 63, a position sensor 67, a monitoring sensor 68, and an AGV control device 69. The AGV moving device 61 drives the AGV 60 along a predetermined travel route, and includes a drive motor for driving the wheels 62 and a steering device. As shown in FIG. 6, the pallet transfer device 63 includes a pair of support members 64 extending in parallel to support the bottom surface of the feeder table 40 (pallet), and an elevator (not shown) for raising and lowering the support members 64. The position sensor 67 detects the travel position of the AGV 60. The monitoring sensor 68 monitors the presence or absence of an obstacle (worker) in the travel direction of the AGV 60, and is configured as, for example, a laser scanner. The AGV control device 69 includes a known CPU, ROM, RAM, etc., and inputs detection signals from the position sensor 67 and the monitoring sensor 68, and outputs drive signals to the AGV moving device 61 and the pallet transfer device 63.

[0029] When the AGV control device 69 is instructed to collect the feeder table 40 (pallet) with the component mounter 20 specified, it controls the AGV movement device 61 so that the AGV 60 moves (travels) along a predetermined travel route with a target position facing the stock area 20B of the specified component mounter 20. When the AGV 60 arrives at the target position, the AGV control device 69 controls the AGV movement device 61 so that the AGV 60 moves forward until the pair of support members 64 enter under the feeder table 40 in the stock area 20B. Then, the AGV control device 69 controls the lifting device so that the support members 64 rise, and controls the AGV movement device 61 so that the AGV 60 moves backward. As a result, the multiple feeders 30 attached to the feeder table 40 are collected by the AGV 60 together with the feeder table 40.

[0030] When the AGV control device 69 is instructed to supply the feeder table 40 (pallet) with the component mounter 20 specified, the AGV control device 69 controls the AGV movement device 61 so that the AGV 60 moves (travels) along a predetermined travel route with the target position being a position facing the stock area 20B of the specified component mounter 20 while holding the feeder table 40 on the pair of support members 64. When the AGV 60 arrives at the target position, the AGV control device 69 controls the AGV movement device 61 so that the AGV 60 moves forward until the pair of support members 64 enter the stock area 20B. Then, the AGV control device 69 controls the lifting device so that the support members 64 are lowered, and controls the AGV movement device 61 so that the AGV 60 moves backward. As a result, the multiple feeders 30 attached to the feeder table 40 are supplied to the stock area 20B together with the feeder table 40. If an obstacle is detected by the monitoring sensor 68 while the AGV 60 is traveling, the AGV control device 69 stops traveling until the obstacle is no longer detected.

[0031] The management device 80 is a general-purpose computer, and includes a CPU 81, a ROM 82, a HDD 83 (storage device), and a RAM 84, as shown in FIG. 7. An input device 85 such as a keyboard and a mouse, and a display 86 are electrically connected to the management device 80. In addition to the production schedule, the HDD 83 stores various information required for production, such as feeder holding information, job information, and status information. These pieces of information are managed for each component mounter 20. Here, the production schedule is a schedule that determines which components are to be mounted on which board S in which order in each component mounter 20, and how many boards S (products) mounted in this way are to be manufactured. The feeder holding information is information about the feeders 30 held by each component mounter 20. The feeder holding information includes position information (slot number) of the attachment position of the feeder 30, ID information of the feeder 30, information on the type of components accommodated in the feeder 30, information on the number of remaining components, and the like, and these pieces of information are stored in the HDD 83 in association with each other for each mounter 20. The feeder holding information is acquired by the management device 80 from the mounting control device 29 of each mounter 20 during production and updated as appropriate. The job information is information regarding mounting instructions (production instructions for boards on which components are mounted) for each mounter 20. The job information includes the type of board, the type of suction nozzle, the type and size of components to be mounted, mounting positions, and the like, and these pieces of information are stored in the HDD 83 in association with each other for each job. The status information is information indicating the operating status of each mounter 20. The status information includes, for example, during production, during setup, and during an abnormality. The status information is acquired by the management device 80 from each mounter 20 and updated as appropriate.

[0032] The management device 80 is connected to the mounting control device 29 by wire so as to be able to communicate with each mounter 20 of each component mounting system 10, and exchanges various information with each mounter 20 of each component mounting system 10. The management device 80 receives operation status from each mounter 20 and updates the status information to the latest information. The management device 80 is also connected to the feeder control device 39 of the feeder 30 attached to the feeder table 40 of each mounter 20 so as to be able to communicate with each other via the mounting control device 29. When a feeder 30 is removed from the mounter 20 or a new feeder 30 is attached to the mounter 20, the management device 80 receives the attachment / detachment status from the corresponding mounter 20 and updates the feeder holding information to the latest information. The management device 80 is also connected to the loader control device 59 by wireless so as to be able to communicate with each other, and exchanges various information with the loader 50. The management device 80 is also connected to the AGV control device 69 by wireless so as to be able to communicate with each other, and exchanges various information with the AGV 60. Furthermore, the management device 80 is communicably connected to the control devices of the printing device 12, the print inspection device 14, and the mounting inspection device, and also exchanges various types of information with the corresponding devices.

[0033] Next, the operation of the component mounting system 10 thus configured will be described. In particular, the operation when a changeover or a component shortage occurs will be described. FIG. 9 is a flowchart showing an example of a feeder supply instruction transmission process executed by the CPU 81 of the management device 80. When the feeder supply instruction transmission process is executed, the CPU 81 of the management device 80 first judges whether or not the current job has been completed (step S100). The judgment of whether or not the job has been completed can be performed by checking the status information. When the CPU 81 judges that the current job has been completed, it judges whether or not a changeover has occurred (step S110), and when it judges that the current job has not been completed, that is, the job is being executed, it judges whether or not a component shortage has occurred (step S120). The judgment of whether or not a changeover has occurred can be performed by checking the status information, and the judgment of whether or not a component shortage has occurred can be performed by checking the number of remaining components in the feeder holding information. When the CPU 81 judges that a changeover has not occurred in step S110 or that a component shortage has not occurred in step S120, it ends the feeder supply instruction transmission process.

[0034] When the CPU 81 determines that a changeover has occurred in step S110, it sets the feeders 30 that are not used for the next job among the used feeders 30 in the supply area 20A as the feeders to be collected (step S130). Next, the CPU 81 sets the feeders 30 that are used for the next job among the feeders 30 in the stock area 20B as the feeders to be supplied (step S140). Then, the CPU 81 acquires the position information (slot number) of the feeders to be collected and the feeders to be supplied from the feeder holding information (step S150), transmits a collection instruction for the feeders to be collected and a supply instruction for the feeders to be supplied to the loader 50 (loader control device 59) (step S160), and ends the feeder supply instruction transmission process. The collection instruction includes designation information of the component mounter 20 that holds the feeders to be collected in the supply area 20A, the current (collection source) position information (slot number) of the feeders to be collected, and the position information of the collection destination of the feeders to be collected. The supply instruction also includes designation information of the mounter 20 that holds the feeder to be supplied in the stock area 20B, current (supply source) location information (slot number) of the feeder to be supplied, and destination location information of the feeder to be supplied. The loader control device 59 that has received the recovery instruction and the supply instruction controls the feeder to be collected to be transferred from the supply area 20A of the specified mounter 20 to the stock area 20B, and the feeder to be supplied to be transferred from the stock area 20B of the specified mounter 20 to the supply area 20A.

[0035] When the CPU 81 determines in step S120 that a component shortage has occurred, it sets the feeder 30 in the supply area 20A that has run out of components as the feeder to be collected (step S170), and sets the feeder 30 in the stock area 20B that contains the same component type as the feeder 30 that has run out of components as the feeder to be supplied (step S180). Then, the CPU 81 acquires the position information (slot number) of the feeder to be collected and the feeder to be supplied from the feeder holding information (step S150), transmits a collection instruction for the feeder to be collected and a supply instruction for the feeder to be supplied to the loader 50 (loader control device 59) (step S160), and ends the feeder supply instruction transmission process. The information contained in the collection instruction and the supply instruction, and the operation of the loader control device 59 that has received the collection instruction and the supply instruction have been described above.

[0036] Next, an operation for stocking the feeder 30 to be used in the stock area 20B will be described. Fig. 10 is a flow chart showing an example of a feeder stock instruction transmission process executed by the CPU 81 of the management device 80. The CPU 81 of the management device 80 first determines whether a changeover by the loader 50 has occurred and the changeover has been completed (step S200). This determination can be made by checking the status information. If the CPU 81 determines that a changeover has not occurred or that a changeover has occurred but has not been completed, it ends the feeder stock instruction transmission process.

[0037] On the other hand, when the CPU 81 determines that a changeover has occurred and that the changeover has been completed, it transmits to the AGV control device 69 a collection instruction for the feeder table 40 in the stock area 20B (step S210). Here, when the changeover by the loader 50 is completed, the used feeder 30 used in the completed job is attached to the stock area 20B. Therefore, the process of step S210 instructs the collection of the feeder table 40 to which the used feeder 30 is attached in the stock area 20B. Then, the CPU 81 transmits to the AGV control device 69 a stock instruction for the feeder table 40 to which the feeder 30 to be used is attached (step S220), and ends the feeder stock instruction transmission process. The feeders 30 to be used include the feeders 30 to be used in the next job onward, as well as spare feeders 30 that are expected to run out of components among the feeders 30 to be used in the job being executed. Moreover, the collection instruction and the stock instruction include designation information for the target component mounter 20.

[0038] Here, the correspondence between the main elements of this embodiment and the main elements described in the claims will be described. That is, the feeder table 40 in the supply area 20A of this embodiment corresponds to the first mounted part of this disclosure, the feeder table 40 in the stock area 20B corresponds to the second mounted part, the component mounter 20 corresponds to the component mounter, the AGV 60 corresponds to the automatic transport device, and the feeder transfer device 53 of the loader 50 corresponds to the feeder transfer device. Also, the feeder table 40 corresponds to the pallet.

[0039] It goes without saying that the present disclosure is in no way limited to the above-described embodiment, and can be embodied in various forms as long as it falls within the technical scope of the present disclosure.

[0040] For example, in the embodiment described above, the loader 50 includes the feeder transfer device 53 and moves between a plurality of component mounters 20, so that the single feeder transfer device 53 transfers the feeders 30 between the supply area 20A and the stock area 20B of each component mounter 20. However, the feeder transfer device may be provided individually for each component mounter 20.

[0041] In the above-described embodiment, the feeder transfer device 53 of the loader 50 is configured to transfer the feeders 30 one by one. However, the feeder transfer device 53 may be configured to transfer the feeders 30 together with the feeder table 40 (pallet) at a time, similar to the pallet transfer device 63 of the AGV 60 described above.

[0042] In the embodiment described above, the pallet transfer device 63 of the AGV 60 is configured to transfer the feeders 30 together with the feeder tables 40 to the stock area 20B of the component mounter 20. However, the pallet transfer device 63 may be configured to transfer the feeders 30 one by one, similar to the feeder transfer device 53 of the loader 50 described above.

[0043] In the above-described embodiment, in the feeder supply instruction transmission process, the CPU 81 transmits a collection instruction and a supply instruction to collect a used feeder 30 (feeder to be collected) from the supply area 20A when the current job is completed and to supply a feeder 30 (feeder to be supplied) to be used in the next job. However, if there is room in the free slots 42 of the feeder table 40 in the supply area 20A, the CPU 81 may transmit a supply instruction to supply the feeder 30 to be used in the next job before the current job is completed (during the execution of the job).

[0044] As described above, the component mounting system of the present disclosure is a component mounting system for mounting components, and has a first mounting portion to which a feeder is attached so that components can be supplied, and a second mounting portion to which the feeder is attached and stored, and is equipped with a plurality of component mounting machines that remove and mount components supplied from the feeder attached to the first mounting portion, an automatic transport device that transports feeders and supplies them to the second mounting portions of the plurality of component mounting machines, and a feeder transfer device that transfers feeders between the first mounting portion and the second mounting portion in each of the plurality of component mounting machines.

[0045] In the component mounting system disclosed herein, the automatic conveying device and the feeder transfer device work together to efficiently replace feeders, thereby improving production efficiency.

[0046] In such a component mounting system of the present disclosure, the automatic transport device may supply a feeder containing components to be used in the next or subsequent jobs to the second mounting unit of the component mounter while the component mounter is executing a job, and the feeder transfer device may transfer a feeder containing components to be used in the next job from the second mounting unit of the component mounter to the first mounting unit when or before the job being executed by the component mounter is finished, thereby enabling smooth job switching.

[0047] In the component mounting system of the present disclosure, the automatic transport device may supply a feeder containing the same component type to the second mounting unit of the component mounter before the mounter runs out of components, and the feeder transfer device may replace the out-of-component feeder with the feeder containing the same component type that is mounted on the second mounting unit when a component shortage occurs in any of the feeders mounted on the first mounting unit of the component mounter. In this way, the replacement of the out-of-component feeder can be performed smoothly.

[0048] Furthermore, in the component mounting system of the present disclosure, the second mounted portion may be configured as a pallet on which a plurality of the feeders are mounted, the automatic transport device may be configured to transport the pallet on which the plurality of feeders are mounted and to attach and detach the feeders together with the pallet to the component mounter, and the feeder transfer device may be configured to individually exchange the feeders between the first mounted portion and the second mounted portion. In this way, a plurality of feeders can be replenished to each component mounter at once, and the replenishment of a plurality of feeders to each component mounter can be performed in a short time.
