Abstract

The present invention provides a mounting system that includes a mounting line formed of multiple mounting-related devices that are arranged side by side and perform mounting-related processes related to component mounting. In the mounting system, parts used for the mounting-related processes are conveyed by a guided vehicle to predetermined sections of the mounting line. The mounting system includes an automatic exchange device that moves along the mounting line and performs automatic exchange operations for exchanging parts between the predetermined sections and the mounting-related devices, and an instruction device that, on the basis of moving status of the guided vehicle, outputs an withdrawal instruction to the automatic exchange device to cause the automatic exchange device to withdraw from a predetermined section of the mounting line before the guided vehicle arrives at the predetermined section.

[0001] This specification discloses an implementation system.

Background Art

[0002] Conventionally, there has been known an implementation system including an implementation line where implementation-related devices such as an implementation apparatus for mounting components on a substrate and a storage for members used in implementation are arranged side by side, and a loader for taking out members from the storage and supplying them to each implementation-related device or taking out members from the implementation-related device and collecting them in the storage (see, for example, Patent Document 1). In this implementation system, an operation button or a human sensor is provided in the storage, and when the operation of the operator in the storage is detected by the operation button or the human sensor, the loader is controlled so as not to enter the work area.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In some cases, the above-described implementation system may be configured such that members are transported to a predetermined location such as a storage or recovered from a predetermined location using an automatic or hand-pushed transport vehicle. However, when the loader is working at a predetermined location first, since it does not approach the range where the operation button is operated or detected by the human sensor, it is necessary to wait for the transport vehicle until the work of the loader is completed and the retreat is completed, and the transport efficiency of the members by the transport vehicle is reduced.

[0005] The main object of the present disclosure is to efficiently transport members by a transport vehicle.

Means for Solving the Problems

[0006] To achieve the above main object, the present disclosure has adopted the following means.

[0007] The implementation system of the present disclosure is an implementation system including an implementation line on which a plurality of implementation-related devices for performing implementation-related processing related to component implementation are arranged side by side, and members used in the implementation-related processing are transported to a predetermined location on the implementation line by a transport vehicle, an automatic exchange device that moves along the implementation line and performs an automatic exchange operation of the member between the predetermined location and the implementation-related device, and an instruction device that outputs an evacuation instruction to the automatic exchange device so that the automatic exchange device evacuates from the predetermined location before the transport vehicle arrives at the predetermined location on the implementation line based on the movement status of the transport vehicle, and is characterized by comprising the above.

[0008] In the implementation system of the present disclosure, based on the movement status of the transport vehicle, an evacuation instruction is output so that the automatic exchange device evacuates from the predetermined location before the transport vehicle arrives at the predetermined location on the implementation line. For this reason, when the transport vehicle approaches the predetermined location on the implementation line, it means that the automatic exchange device is in the process of evacuating from the predetermined location or the evacuation has been completed. Therefore, the waiting time for the transport vehicle to wait for the evacuation of the automatic exchange device can be reduced, and the transport of members by the transport vehicle can be efficiently performed.

Embodiments for Carrying Out the Invention

[0010] Next, embodiments for carrying out the present disclosure will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing an example of the mounting system 1. FIG. 2 is an explanatory diagram showing an outline of the configuration of the mounting line 10. FIG. 3 is an explanatory diagram showing an outline of the configuration of the mounting device 20. FIG. 4 is a block diagram showing a configuration related to the control of the mounting system 1. In the present embodiment, the left-right direction (X-axis), the front-rear direction (Y-axis), and the up-down direction (Z-axis) shall be as shown in FIGS. 2 and 3.

[0011] The mounting system 1 includes a plurality (two are exemplified in FIG. 1) of mounting lines 10 (10A, 10B) in which mounting-related processes for mounting components on the substrate S are performed, and a transport system 50 performs the transport processes of various members used in the mounting-related processes. Further, the mounting system 1 includes a management device 5 that manages the processes of the entire system. Each mounting line 10 includes a plurality of mounting-related devices that perform mounting-related processes, and a mounting control device 38 that controls the plurality of mounting-related devices. The transport system 50 includes a plurality of automatic guided vehicles 55 (hereinafter referred to as AGV 55), a charging station 57, and a transport control device 58. Note that the number of mounting lines 10 is not limited to a plurality, and may be one.

[0012] Among the plurality of mounting-related devices of the mounting line 10, for example, one or more of a printing device 12, a printing inspection device 14, a storage 16, a mounting device 20, a mounting inspection device 28, a reflow device 30, a reflow inspection device 32, etc. are included. These are arranged side by side along the transport direction (X-axis direction) of the substrate S. Further, in the present embodiment, a loader 18 that is movable along the mounting line 10 is provided. Note that each mounting line 10 (10A, 10B) has the same configuration, but may have different configurations. In FIGS. 2 and 4, only one mounting line 10 (10A) is illustrated.

[0013] The printing device 12 prints on the substrate S (see FIG. 3) by pressing solder into the pattern holes formed in the screen mask. The printing inspection device 14 inspects the state of the solder printed by the printing device 12. The mounting inspection device 28 inspects the mounting state of the components mounted on the substrate S by the mounting device 20. The reflow device 30 heats the substrate S on which components are arranged on the solder to melt the solder, and then cools it to electrically connect and fix each component on the substrate S. The reflow inspection device 32 inspects the state of the components on the substrate S after reflow.

[0014] A plurality of mounting devices 20 are arranged along the conveyance direction of the substrate S, and mount components on the substrate S. As shown in FIG. 3, the mounting device 20 includes a mounting unit 22 and a feeder 24. The mounting unit 22 is a unit that picks up components with a mounting head equipped with a pickup member such as a nozzle and mounts them on the substrate S. The feeder 24 is configured as a tape feeder in which a reel wound with a tape holding components at a predetermined pitch is detachably attached, and the tape is fed out by rotating the reel to supply the components.

[0015] The loader 18 is configured to be movable within a moving area (the dotted area in FIG. 1) along the conveyance direction of the substrate S on the front side of the plurality of mounting devices 20 and the storage 16. The loader 18 moves within the moving area and performs an automatic exchange operation (recovery and replenishment) to automatically exchange the members used for the mounting process. For example, the loader 18 automatically exchanges the feeder 24, which is an exchangeable work unit for the mounting device 20, but it is sufficient if members used for mounting-related processes such as the head, pickup members such as nozzles, solder storage members, and screen masks provided in the mounting unit 22 can be automatically exchanged.

[0016] The storage vault 16 is an in-line storage vault that stores various members used in implementation-related processes within each implementation line 10. For example, it stores the feeder 24. In the storage vault 16, the operator M can supply (replenish) or retrieve the feeder 24. Also, the loader 18 can automatically exchange the feeder 24 with respect to the storage vault 16. It can take out the necessary feeder 24 from the storage vault 16 and supply it to the mounting device 20, or take out the used feeder 24 from the mounting device 20 and retrieve it to the storage vault 16. Also, in the storage vault 16, the AGV 55 can also supply or retrieve the feeder 24. Further, the storage vault 16 is partitioned into a plurality of storage sections such as a first storage section 16a and a second storage section 16b, and the feeder 24 can be stored in each storage section.

[0017] The mounting control device 38 is a general-purpose computer including a CPU, ROM, RAM, HDD, etc., to which an input device such as a keyboard and a mouse and an output device such as a display are connected. In a storage device such as the HDD of the mounting control device 38, a production plan for the substrate S and production information related to the production of the substrate S are stored. The production plan defines the mounting order of components on the substrate S, the production quantity of the substrate S, etc. Also, the production information includes information indicating the printing position of solder on the substrate S, information on the components mounted on the substrate S, the mounting positions of each component, etc. The component information indicates, as the inventory status of the components, the arrangement status of the feeder 24 in each mounting device 20 and the storage vault 16 in addition to the types of components mounted in each mounting device 20. During the production of the substrate S, the mounting control device 38 gives various command signals to the printing device 12, the printing inspection device 14, the loader 18, the mounting device 20, the mounting inspection device 28, the reflow device 30, the reflow inspection device 32, etc. based on the production plan and the production information. Also, the mounting control device 38 is communicably connected to the conveyance control device 58, and exchanges information such as information on the working status of the loader 18 and information on the traveling status of the AGV 55.

[0018] Although not shown in the figure, the AGV 55 is equipped with a motor for rotating the wheels and a battery for supplying power, etc., and automatically transports members used for mounting-related processes such as the feeder 24 between the warehouse 60 and the storage 16. The AGV 55, for example, takes out the necessary feeder 24 from the warehouse 60 and automatically transports it to the storage 16 for feeding (supply), or collects the used feeder 24 from the storage 16 and automatically transports it to the warehouse 60 for storage. Note that the AGV 55 automatically transports the feeder 24, but it may be any device that can automatically transport members used for mounting-related processes such as the sampling members such as the head and nozzle provided in the mounting unit 22, the solder storage member, and the screen mask.

[0019] Here, between the AGV 55 and the storage 16, for example, a plurality of feeders 24 can be automatically exchanged all at once with the magazine 55a as a predetermined mounting member. The loader 18 takes in and out the feeder 24 with respect to the other storage unit when one of the above-described first storage unit 16a and second storage unit 16b of the storage 16 is empty, and collects the used feeder 24 in the other storage unit. When the AGV 55 performs feeding and collection of the feeder 24, first, a plurality of feeders 24 to be fed are dispensed together with the magazine 55a to one of the first storage unit 16a and second storage unit 16b of the storage 16 for feeding. Next, the AGV 55 receives and collects a plurality of feeders 24 collected in the other of the first storage unit 16a and second storage unit 16b together with the magazine 55a. The AGV 55 automatically transports the collected feeder 24 to the warehouse 60.

[0020] In the warehouse 60, various members such as the feeder 24 stored by the operator M and the feeder 24 automatically transported by the AGV 55 are stored. Note that the AGV 55 can take in and out a plurality of feeders 24 together with the magazine 55a with respect to the warehouse 60. Further, the charging station 57 is a facility for charging the batteries of one or more AGVs 55 parked at a predetermined charging position. Note that the charging station 57 may be configured to be able to supply power when the connector is connected when the AGV 55 is parked at a predetermined charging position, or may be configured to be able to supply power non - contact.

[0021] The conveyance control device 58 is a general - purpose computer including a CPU, ROM, RAM, HDD, etc., to which an input device such as a keyboard and a mouse and an output device such as a display are connected. The conveyance control device 58 is configured to be able to communicate wirelessly with the AGV 55, acquire the position information of the AGV 55, perform travel control such as starting and standby of the AGV 55, acquire the state such as the remaining battery level of the AGV 55, and also perform charging control of the AGV 55 at the charging station 57.

[0022] The management device 5 is a general-purpose computer including a CPU, ROM, RAM, HDD, etc., to which input devices such as a keyboard and a mouse and output devices such as a display are connected. The management device 5 is configured to be communicable with each mounting control device 38 and conveyance control device 58 of each mounting line 10. The management device 5 transmits the production plan and production information of the substrate S of each mounting line 10 to each mounting control device 38. The management device 5 receives from each mounting control device 38 the production status of the substrate S, the usage status of the feeder 24 required for production, the arrangement status of the feeder 24 in the storage 16, etc. Note that the production status includes the status of setup change such as the replacement of the screen mask and the replacement of the feeder 24 as production preparations for different types of substrates. Further, the management device 5 transmits the travel plan (conveyance plan) of each AGV 55 to the conveyance control device 58, and receives from the conveyance control device 58 the travel status, battery remaining amount, charging status, etc. of each AGV 55. Note that the management device 5 creates a travel plan including the conveyance schedule and charging schedule of the feeder 24 in each AGV 55 based on the production plan of the substrate S of each mounting line 10, the production status of the substrate S, information regarding the feeder 24 required for production, etc.

[0023] Next, the operation of the mounting system 1 configured in this way, particularly the movement control of the AGV 55 and the retraction control of the loader 18, will be described. FIG. 5 is a sequence showing an example of the movement control of the AGV 55 and the retraction control of the loader 18.

[0024] First, the conveyance control device 58 starts the movement of the AGV 55 toward the storage 16 as the destination (S100), and waits for the AGV 55 to arrive at the retraction start position P1 based on the position information (movement status) of the AGV 55 (S110). The retraction start position P1 is a position set in front of the destination storage 16, and the details will be described later. When the conveyance control device 58 determines that the AGV 55 has arrived at the retraction start position P1, it transmits (outputs) a retraction instruction to retract the loader 18 from in front of the storage 16 (S120).

[0025] The implementation control device 38 that has received the avoidance instruction determines whether the loader 18 is in the process of automatically replacing the feeder 24 in the storage 16 (S200). If it is determined that the loader 18 is working in the storage 16, the loader 18 is controlled to either temporarily interrupt the work at the end of the work or to retreat from the storage 16 when the work is completed (S210). For example, when the feeder 24 collected by the loader 18 is being stored in the storage 16, and then another feeder 24 is taken out and moved to the mounting device 20 to supply the feeder 24, the period until the feeder 24 is stored may be used as the end of the work. That is, the implementation control device 38 may temporarily interrupt the work and retreat the loader 18 when the loader 18 stores the feeder 24. Alternatively, the implementation control device 38 may retreat the loader 18 after the loader 18 stores the feeder 24, takes out another feeder 24, and the work is completed.

[0026] On the other hand, when the implementation control device 38 determines that the loader 18 is not working in the storage 16, it controls the loader 18 to retreat without moving in front of the storage 16 (S220). Note that in S210 and S220, the work of the loader 18 outside the storage 16 is permitted. That is, the implementation control device 38 retreats the loader 18 from the storage 16 so that the loader 18 does not interfere with the AGV 55 moving to the storage 16, but permits the loader 18 to perform operations such as automatically replacing the feeder 24 for the mounting device 20.

[0027] When the transfer control device 58 sends a retreat instruction in S120, it waits for the AGV 55 to arrive at the retreat confirmation position P2 based on the position information of the AGV 55 (S130). Here, FIG. 6 is an explanatory diagram showing an example of the retreat start position P1 and the retreat confirmation position P2. Both the retreat start position P1 and the retreat confirmation position P2 are positions determined on the travel route to the storage warehouse 16 which is the destination, and in the order of the retreat start position P1 and the retreat confirmation position P2 from the one farther from the storage warehouse 16. The retreat start position P1 is the position for sending (outputting) the above-mentioned retreat instruction, and is the position for starting the retreat of the loader 18. Also, the retreat confirmation position P2 is the position for confirming whether the loader 18 that has received the retreat instruction has completed the retreat. Normally, each position is determined so that the loader 18 moves to the dotted line position in FIG. 6 or the like between the retreat start position P1 and the retreat confirmation position P2 and the retreat from the storage warehouse 16 is completed. Further, the retreat confirmation position P2 is determined as a position that does not interfere with the work or movement of the loader 18 even when the AGV 55 waits at that position.

[0028] Then, when the transfer control device 58 determines in S130 that the AGV 55 has arrived at the retreat confirmation position P2, it inquires the mounting control device 38 about the completion of the retreat of the loader 18 (S140). The mounting control device 38 that has received the inquiry transmits to the transfer control device 58 the retreat status of the loader 18, that is, whether the loader 18 has retreated from in front of the storage warehouse 16, based on the current position of the loader 18 (S230).

[0029] Based on the retraction status transmitted from the mounting control device 38, the transfer control device 58 determines whether it can confirm the completion of the retraction of the loader 18 (S150). If it cannot be determined that the retraction is completed, the transfer control device 58 sends (outputs) a standby instruction to the AGV 55 to standby at the retraction confirmation position P2 (S160), and repeats the processes of S140 and S150. That is, the transfer control device 58 waits to confirm the completion of the retraction of the loader 18 while causing the AGV 55 to standby at the retraction confirmation position P2. Then, when the transfer control device 58 determines in S150 that the retraction of the loader 18 is completed, it moves the AGV 55 in front of the storage 16 to execute the work (S170) and waits for the work to be completed (S180). In S170, the AGV 55 performs operations such as delivering the feeder 24 transported to one of the first storage section 16a and the second storage section 16b of the storage 16, or retrieving the feeder 24 from the other of the first storage section 16a and the second storage section 16b.

[0030] Then, when the transfer control device 58 determines in S180 that the work of the AGV 55 is completed, it starts the movement of the AGV 55 with the destination being the warehouse 60 (S190) and sends a work completion notification to the mounting control device 38 (S195). Note that the running control of the AGV 55 to the warehouse 60 is not related to the gist of the present invention, so the description is omitted. The mounting control device 38 that has received the work completion notification permits the movement and work of the loader 18 to the storage 16 (S240). Therefore, the loader 18 that has retracted from the storage 16 can move back to the storage 16 to perform the work.

[0031] Here, the correspondence between the components of the present embodiment and the components of the present disclosure is clarified. The mounting line 10 of the present embodiment corresponds to the mounting line, the loader 18 corresponds to the automatic changer, the AGV 55 corresponds to the transport vehicle, and the transfer control device 58 corresponds to the instruction device.

[0032] In the implementation system 1 described above, since a retreat instruction is output to the loader 18 before the AGV 55 arrives at the storage 16 based on the running status of the AGV 55, when the AGV 55 approaches the storage 16, the loader 18 will be in the process of retreating or the retreat will have been completed. Therefore, the waiting time for the AGV 55 to wait for the retreat of the loader 18 can be reduced, so that the AGV 55 can efficiently transport the feeder 24.

[0033] Also, since a retreat instruction is output at the timing when the AGV 55 arrives at the retreat start position P1, the retreat instruction can be output with simple processing.

[0034] Also, when the completion of the retreat of the loader 18 cannot be confirmed, the AGV 55 is made to wait at a retreat confirmation position P2 (a predetermined waiting position) closer to the storage 16 than the retreat start position P1, so that if the retreat of the loader 18 is completed, the AGV 55 can be quickly moved to the storage 16.

[0035] Note that the present disclosure is not limited to the above-described embodiments, and it goes without saying that various embodiments can be implemented as long as they belong to the technical scope of the present disclosure.

[0036] For example, in the above-described embodiment, in S110, the conveyance control device 58 determines whether or not the AGV 55 has arrived at the retreat start position P1 based on the position information of the AGV 55, but it is not limited thereto. The conveyance control device 58 can predict the arrival timing at the retreat start position P1 from the movement start timing of the AGV 55, the speed of the AGV 55, the distance to the retreat start position P1, etc., and in S110, it can determine whether or not the arrival timing has been reached. That is, the conveyance control device 58 may transmit a retreat instruction for the loader 18 when the arrival timing at which the arrival at the retreat start position P1 is predicted is reached. Similarly, the conveyance control device 58 may confirm the completion of the retreat of the loader 18 when the arrival timing at which the arrival at the retreat confirmation position P2 is predicted is reached.

[0037] In the embodiment, the evacuation start position P1 determined at a fixed position is used, but it is not limited to this, and the evacuation start position P1 may be changeable. FIG. 7 is a sequence showing the movement control of the AGV 55 and the evacuation control of the loader 18 in a modified example. In the modified example, mainly the parts different from those in FIG. 5 are shown in FIG. 7, and the same processes as those in the embodiment are denoted by the same reference numerals and the description thereof is omitted.

[0038] In this modified example, when the AGV 55 starts moving in S100, the mounting control device 38 acquires the working status of the loader 18 (S250), estimates the evacuation time required for the loader 18 based on the working status, and transmits it to the conveyance control device 58 (S260). Note that the conveyance control device 58 transmits a notification to the mounting control device 38 of the mounting line 10 having the destination storage 16 that the AGV 55 has started moving, and the mounting control device 38 that has received the notification may estimate and transmit the evacuation time required for the loader 18.

[0039] Further, as the working status of the loader 18, the mounting control device 38 acquires the content of the currently executing work and the next work, and estimates the evacuation time required by adding the time until the completion or the end of the work and the time until the completion of the evacuation from in front of the storage 16. For example, when the loader 18 is taking out the feeder 24 from the storage 16 and moving and supplying the feeder 24 to the mounting device 20, the mounting control device 38 estimates the evacuation time required by adding the time until the completion of taking out the feeder 24 and the time until the completion of the evacuation. Also, when the loader 18 is storing the recovered feeder 24 in the storage 16 and then taking out another feeder 24 and supplying it to the mounting device 20, the mounting control device 38 may set the time until the feeder 24 is stored as the end of the work, interrupt the work once, and evacuate the loader 18. In this case, the mounting control device 38 estimates the evacuation time required by adding the time until the completion of storing the feeder 24 and the time until the completion of the evacuation. Note that after the AGV 55 has completed the work at the storage 16 and started moving, the mounting control device 38 may cause the loader 18 to continue the interrupted work.

[0040] When the transfer control device 58 receives the evacuation required time, it determines whether the evacuation required time exceeds the reference required time (S102). When the transfer control device 58 determines that the evacuation required time does not exceed the reference required time, it sets the reference evacuation start position P1 (S104). Note that the reference evacuation start position P1 is the same position as the evacuation start position P1 in the embodiment. On the other hand, when the transfer control device 58 determines that the evacuation required time exceeds the reference required time, it sets the evacuation start position P1 adjusted so that the farther it is from the reference as the evacuation required time is longer (S106). When the evacuation start position P1 is adjusted to be farther from the reference, the timing at which the evacuation instruction is output in subsequent S110 and S120 becomes earlier. That is, in the modified example, the evacuation start position P1 is adjusted so that the timing at which the evacuation instruction is output becomes earlier as the evacuation required time is longer. Thereby, when it is predicted from the working condition of the loader 18 that the evacuation will take time, the evacuation instruction can be output earlier. Therefore, since the evacuation instruction can be output at an appropriate timing according to the working condition of the loader 18, the standby time of the AGV 55 can be more reliably reduced. Note that even if the evacuation required time is shorter than the reference required time, by setting the timing of outputting the evacuation instruction as per the reference, the evacuation instruction can be output to the loader 18 earlier to cause evacuation, so that the standby time of the AGV 55 can be surely reduced.

[0041] In this modified example, it is assumed that whether to set the reference evacuation start position P1 or adjust the evacuation start position P1 so that it is farther from the reference as the evacuation required time is longer differs based on whether the evacuation required time exceeds the reference required time, but it is not limited thereto. For example, without providing the reference evacuation start position P1 and without comparing the evacuation required time with the reference required time, the evacuation start position P1 may be simply adjusted so that the farther it is from the storage 16 as the evacuation required time is longer, that is, the timing of outputting the evacuation instruction becomes earlier.

[0042] In the embodiment, when the transfer control device 58 could not confirm the completion of the retraction of the loader 18, the AGV 55 was made to wait at the retraction confirmation position P2. However, the present invention is not limited to this, and the AGV 55 may be made to wait at a position different from the retraction confirmation position P2. That is, the AGV 55 may be made to wait at a position closer to the storage rack 16, which is the destination, than the retraction confirmation position P2. Alternatively, regardless of whether the completion of the retraction of the loader 18 can be confirmed, the AGV 55 is once stopped at the retraction confirmation position P2. If the completion of the retraction of the loader 18 cannot be confirmed, the AGV 55 may be made to wait as it is. If the completion of the retraction of the loader 18 can be confirmed, the AGV 55 may be moved again.

[0043] In the embodiment, the transfer control device 58 transmitted a retraction instruction to the loader 18. However, the present invention is not limited to this, and the transfer control device 58 may transmit a notification of arrival at the retraction start position P1 to the mounting control device 38, and the mounting control device 38 that has received the arrival notification may transmit a retraction instruction to the loader 18. Alternatively, the transfer control device 58 may transmit the position information of the AGV 55 to the mounting control device 38, and the mounting control device 38 may determine the arrival at the retraction start position P1 based on the position information and transmit a retraction instruction to the loader 18.

[0044] In the embodiment, the transfer of the feeder 24 to the mounting line 10 was performed by the AGV 55. However, the present invention is not limited to this, and for example, it may be performed by a manual transfer cart such as a worker's handcart, and the AGV 55 may not be provided. Even when the feeder 24 is transferred by a worker's handcart or the like, since it may be necessary to wait for the retraction of the loader 18 from the storage rack 16, there is an effect similar to that of the embodiment in which the loader 18 is retracted in advance. The mounting control device 38 may acquire the position information of the handcart (worker) based on a well-known positioning system such as a mobile terminal of a worker operating the handcart or a GPS provided on the handcart, and output a retraction instruction to the loader 18 based on the position information.

[0045] In the embodiment, members used for mounting-related processes such as the feeder 24 are transported by the AGV 55 to the dedicated storage 16 within the mounting line 10. However, the present invention is not limited to this, and any member that can be transported to a predetermined location within the mounting line 10 is acceptable. For example, it may be transported to a storage provided in each device (such as the printing device 12, the printing device 14, the mounting device 20, the mounting inspection device 28, etc.), such as a storage provided below the mounting device 20 in FIG. 3.

[0046] Here, the mounting system of the present disclosure may be configured as follows. For example, in the mounting system of the present disclosure, the instruction device may output the retraction instruction at the timing when the transport vehicle arrives at a predetermined retraction start position or at the timing when arrival at the retraction start position is predicted. In this way, the retraction instruction can be output with simple processing.

[0047] In the mounting system of the present disclosure, the instruction device estimates the retraction time required until the automatic exchange device that has received the retraction instruction completes retraction based on the working status of the automatic exchange device, and adjusts the retraction start position so that the earlier the retraction time required, the earlier the timing. In this way, since the retraction instruction can be output at an appropriate timing according to the working status of the automatic exchange device, the waiting time of the transport vehicle can be more reliably reduced.

[0048] In the mounting system of the present disclosure, the instruction device confirms the completion of retraction of the automatic exchange device before the transport vehicle arrives at the predetermined location, and when the completion of retraction cannot be confirmed, outputs a waiting instruction so that the transport vehicle waits at a predetermined waiting position in front of the predetermined location and does not interfere with the automatic exchange device. In this way, when the retraction of the automatic exchange device is not completed, the transport vehicle can be made to wait at an appropriate position, and as soon as the automatic exchange device retracts, the transport vehicle can be quickly moved to the predetermined location.

Industrial Applicability

[0049] The present disclosure can be used in a mounting system including an automatic exchange device for members and the like.
