Description

[Technical Field]

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

[0002] Conventionally, there has been known a mounting system that includes mounting-related equipment such as a mounting device that mounts components on a board, and an exchange device that supplies and collects components used in mounting to and from the mounting-related equipment (see, for example, Patent Document 1). This mounting system describes an exchange device that includes a table moving device that allows an exchange table to move back and forth in a predetermined direction behind the mounting device main body, and a carriage that is disposed behind the table moving device and is movable along the predetermined direction. The exchange table, which carries the components, is then slid between the mounting device and the table moving device and between the table moving device and the carriage, thereby exchanging the components together with the exchange table.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 5-75293 Summary of the Invention [Problem to be solved by the invention]

[0004] In some cases, the mounting system described above is configured to collect used components in a predetermined location and then have the components collected from the predetermined location by an automated guided vehicle. However, if the automated guided vehicle arrives at the predetermined location and the components are not collected as scheduled, the automated guided vehicle must wait until the components are collected, which reduces the efficiency of the component collection by the guided vehicle.

[0005] The main object of the present disclosure is to efficiently collect components using an automated guided vehicle. [Means for solving the problem]

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

[0007] The mounting system of the present disclosure includes: A mounting system including a mounting line in which a plurality of mounting-related devices that perform mounting-related processes related to component mounting are arranged side by side, and in which members used in the mounting-related processes are collected to a predetermined location, and in which the members are collected from the predetermined location by an automatic guided vehicle, a control device that controls the travel of the automated guided vehicle to the predetermined location based on the collection status of the member at the predetermined location; The gist of the project is to provide the following:

[0008] In the mounting system of the present disclosure, the travel of an automated guided vehicle to a predetermined location is controlled based on the collection status of components at the predetermined location. This prevents the automated guided vehicle from arriving at or approaching the predetermined location without completing collection of components. This reduces the waiting time that the automated guided vehicle waits to collect components at the predetermined location, allowing the automated guided vehicle to efficiently collect components.

[0010] Next, an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is an explanatory diagram showing an example of a mounting system 1. Fig. 2 is an explanatory diagram showing an outline of the configuration of a mounting line 10. Fig. 3 is an explanatory diagram showing an outline of the configuration of a mounting device 20. Fig. 4 is a block diagram showing a configuration related to control of the mounting system 1. 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. 2 and 3.

[0011] The mounting system 1 includes a plurality of mounting lines 10 (10A, 10B) (two are illustrated in FIG. 1) where mounting-related processes relating to mounting components on a board S are performed, and a transport system 50 transports various members used in the mounting-related processes. The mounting system 1 also 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 also includes a plurality of automatic guided vehicles 55 (hereinafter, AGVs 55), a charging station 57, and a transport control device 58. The number of mounting lines 10 is not limited to multiple, and may be one.

[0012] The multiple mounting-related devices on the mounting line 10 include, for example, one or more of a printing device 12, a print inspection device 14, a storage 16, a mounting device 20, a mounting inspection device 28, a reflow device 30, and a reflow inspection device 32. These are arranged side by side along the transport direction (X-axis direction) of the board S. The mounting line 10 of this embodiment also includes a loader 18 that is movable along the mounting line 10. Note that each mounting line 10 (10A, 10B) has the same configuration, but may have different configurations, and only one mounting line 10 (10A) is shown in FIGS. 2 and 4.

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

[0014] A plurality of mounting devices 20 are arranged along the transport direction of the board S, and mount components on the board 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 using a mounting head equipped with a picking member such as a nozzle and mounts them on the board S. The feeder 24 is configured as a tape feeder to which a reel around which a tape that holds the components at a predetermined pitch is detachably attached, and which feeds the tape by rotating the reel to supply the components.

[0015] The loader 18 is configured to be movable within a movement area (dotted line area in FIG. 1) along the transport direction of the substrate S, on the front side of the multiple mounting devices 20 and the storage 16. The loader 18 moves within the movement area and performs automatic replacement work to automatically replace (collect or replenish) components used in the mounting process. For example, the loader 18 automatically replaces the feeder 24, which is a replaceable working unit for the mounting device 20, but it is sufficient if the loader 18 can automatically replace components used in mounting-related processes, such as collection components such as heads and nozzles, solder containing components, and screen masks, which are provided in the mounting unit 22.

[0016] The storage 16 is an in-line storage that stores various components used in mounting-related processes within each mounting line 10, and stores, for example, feeders 24. In the storage 16, a worker M can supply (refill) and retrieve feeders 24. In addition, a loader 18 can automatically replace feeders 24 with respect to the storage 16, removing a required feeder 24 from the storage 16 and refilling it into the mounting device 20, or removing a used feeder 24 from the mounting device 20 and retrieving it into the storage 16. In addition, the AGV 55 can also replenish and retrieve feeders 24 from the storage 16. In addition, the storage 16 is partitioned into multiple storage sections, such as a first storage section 16a and a second storage section 16b, and feeders 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., and is connected to input devices such as a keyboard and mouse, and output devices such as a display. A storage device such as an HDD of the mounting control device 38 stores a production plan for the boards S and production information related to the production of the boards S. The production plan specifies the order in which components are mounted on the boards S and the number of boards S to be produced. The production information also includes information indicating the solder printing position on the boards S, information on the components to be mounted on the boards S, and the mounting position of each component. The component information indicates the type of components to be mounted by each mounting device 20, as well as the component inventory status, such as the placement status of feeders 24 in each mounting device 20 and the storage room 16. During the production of the boards S, the mounting control device 38 issues various command signals to the printing device 12, print inspection device 14, loader 18, mounting device 20, mounting inspection device 28, reflow device 30, reflow inspection device 32, etc., based on the production plan and production information. The mounting control device 38 is also connected to the transport control device 58 so as to be able to communicate with it, and exchanges information relating to the working status of the loader 18 and information relating to the traveling status of the AGV 55, etc.

[0018] Although not shown, the AGV 55 includes a motor for rotating wheels and a battery for supplying power, and automatically transports components used in mounting-related processes, such as the feeders 24, between the warehouse 60 and the storage 16. The AGV 55, for example, retrieves necessary feeders 24 from the warehouse 60 and automatically transports them to the storage 16 for distribution (supply), or collects used feeders 24 from the storage 16 and automatically transports them to the warehouse 60 for storage. Note that although the AGV 55 automatically transports the feeders 24, it may also be any AGV that automatically transports components used in mounting-related processes, such as collection components such as heads and nozzles, solder containing components, and screen masks, which are provided in the mounting unit 22.

[0019] Here, between the AGV 55 and the storage 16, for example, when a plurality of feeders 24 are loaded in a magazine 55a as a predetermined loading member, the magazine 55a can be automatically exchanged all at once. When one of the first storage section 16a and the second storage section 16b of the storage 16 is empty, the loader 18 takes out and puts feeders 24 into the other storage section and recovers used feeders 24 to the other storage section. When distributing and recovering feeders 24, the AGV 55 first dispenses the plurality of feeders 24 to be distributed together with the magazine 55a to one of the first storage section 16a and the second storage section 16b of the storage 16 and delivers them. Next, the AGV 55 receives and recovers the plurality of feeders 24 recovered in the other storage section of the first storage section 16a and the second storage section 16b. The AGV 55 automatically transports the collected feeder 24 to the warehouse 60.

[0020] Warehouse 60 stores various components, such as feeders 24 stored by worker M and feeders 24 automatically transported by AGV 55. AGV 55 can simultaneously load and unload multiple feeders 24 together with their magazines 55a into and out of warehouse 60. Charging station 57 is a facility that charges the batteries of one or more AGVs 55 parked at a predetermined charging position. Charging station 57 may be configured so that a connector is connected to charge AGV 55 when AGV 55 is parked at the predetermined charging position, enabling power supply, or may be configured so that power can be supplied contactlessly.

[0021] The transport control device 58 is a general-purpose computer including a CPU, ROM, RAM, HDD, etc., and is connected to input devices such as a keyboard and mouse, and output devices such as a display. The transport control device 58 is configured to be able to communicate with the AGV 55 wirelessly, and acquires position information of the AGV 55, controls the AGV 55's travel, such as departure and standby, and acquires the status of the AGV 55, such as the remaining battery charge. The transport control device 58 also controls charging of the AGV 55 at the charging station 57, etc.

[0022] The management device 5 is a general-purpose computer including a CPU, ROM, RAM, HDD, etc., and is connected to input devices such as a keyboard and a mouse and output devices such as a display. The management device 5 is configured to be able to communicate with each mounting control device 38 and transport control device 58 of each mounting line 10. The management device 5 transmits production plans and production information for the boards S on each mounting line 10 to each mounting control device 38. The management device 5 receives information such as the production status of the boards S, the usage status of the feeders 24 required for production, and the placement status of the feeders 24 in the storage 16 from each mounting control device 38. The production status includes the status of setup changes such as replacing screen masks and replacing feeders 24 in preparation for production of different types of boards. The management device 5 also transmits a driving plan (transportation plan) for each AGV 55 to the transport control device 58, and receives information such as the driving status, remaining battery charge, and charging status of each AGV 55 from the transport control device 58. The management device 5 creates a driving plan including transport schedules and charging schedules for the feeders 24 for each AGV 55 based on the production plan for the boards S of each mounting line 10, the production status of the boards S, and information on the feeders 24 required for production.

[0023] The operation of the mounting system 1 configured in this manner will be described below, particularly the travel control of the AGV 55. Fig. 5 is a flowchart showing an example of AGV travel control, which is executed by the transport control device 58 when the AGV 55 is caused to retrieve the feeder 24 from the storage 16. Fig. 6 is an explanatory diagram showing an example of the manner in which the AGV 55 travels to the storage 16.

[0024] First, the transfer control device 58 acquires the collection status of the feeders 24 in the storage 16 through communication with the mounting control device 38 (S100) and determines whether the collection rate R is equal to or greater than a predetermined rate Rref (S110). The collection rate R indicates the ratio of the number of collected feeders 24 to the number of feeders 24 scheduled to be collected in the destination storage unit (the first storage unit 16a or the second storage unit 16b), i.e., the ratio of the number of collected feeders 24 to the number scheduled for collection. For example, in this embodiment, the predetermined rate Rref is predetermined to a value smaller than 100%, such as 80%. Note that the predetermined rate Rref may be set to 100%, and whether collection is complete may be determined in S110. Alternatively, the result of the determination made by the mounting control device 38 in S110 may be transmitted as the collection status of the feeders 24 in S100. When the transfer control device 58 determines in S110 that the collection rate R is equal to or greater than the predetermined rate Rref, it causes the AGV 55 to start traveling from the travel start position P1 (see FIG. 6) toward the storage 16, which is the destination (S120).

[0025] Then, the transfer control device 58 waits for the AGV 55 to arrive at the standby position P2 (see FIG. 6) based on the position information of the AGV 55 (S130). The standby position P2 is a position before the storage 16, which is the destination, and is determined as a position where the AGV 55 does not interfere with the work or movement of the loader 18 even if it waits. When the transfer control device 58 determines that the AGV 55 has arrived at the standby position P2, it acquires the collection status of the feeder 24 in the storage 16 and the evacuation status of the loader 18 through communication with the mounting control device 38 (S140). Note that the collection status indicates the proportion of the feeder 24 in the storage unit (first storage unit 16a or second storage unit 16b) to which the loader 18 is to be collected, as in S100. Next, the transfer control device 58 determines whether collection of the feeder 24 has been completed, i.e., whether the collection percentage R has reached 100% (S150), and whether the loader 18 has evacuated from in front of the storage 16 (S160). It should be noted that, once the collection of the feeder 24 is completed, the mounting control device 38 promptly moves the loader 18 away from in front of the storage 16. Alternatively, the mounting control device 38 may, by communication with the transport control device 58, suspend the operation of the loader 18 and move the loader 18 away from in front of the storage 16 before the AGV 55 arrives at the standby position P2.

[0026] If the transfer control device 58 determines in S150 that the collection of the feeder 24 has not been completed, or if it determines in S160 that the loader 18 has not retreated from in front of the storage 16, it outputs a standby instruction to the AGV 55 to wait at standby position P2 (S170), and repeats the processes of S140 to S160. That is, the transfer control device 58 waits for the loader 18 to retreat after the collection of the feeder 24 in the storage 16 has been completed, while making the AGV 55 wait at standby position P2. Note that the transfer control device 58 may first perform the process of S170 to make the AGV 55 wait at standby position P2, and then perform the processes of S140 to S160.

[0027] On the other hand, when the transport control device 58 determines that the retrieval of the feeder 24 to the storage 16 is complete and the loader 18 has retreated, it moves the AGV 55 to the storage unit of the retrieval destination (for example, the first storage unit 16a in FIG. 6 ) and executes the retrieval work of the feeder 24 (S180). Next, the transport control device 58 waits for the retrieval work of the feeder 24 by the AGV 55 to be completed (S190). When it determines that the retrieval work is completed, it starts the travel of the AGV 55 with the warehouse 60 as the destination (S200), retrieving the feeder 24 to the warehouse 60, and ends the AGV travel control. Note that the travel control of the AGV 55 to the warehouse 60 is not part of the gist of the present invention, so a description thereof will be omitted. When the transport control device 58 starts the travel of the AGV 55, it transmits a work completion notification to the mounting control device 38. Upon receiving the work completion notification, the mounting control device 38 permits the loader 18 to move to the storage 16 and perform the work.

[0028] Here, the correspondence between the components of this embodiment and the components of the present disclosure will be clarified. In this embodiment, the mounting line 10 corresponds to the mounting line, the AGV 55 corresponds to the automatic guided vehicle, and the transport control device 58 corresponds to the control device.

[0029] In the mounting system 1 described above, the travel of the AGV 55 to the storage 16 is controlled based on the collection status of the feeder 24 in the storage 16, so it is possible to prevent a situation in which collection of the feeder 24 is not completed when the AGV 55 approaches the storage 16. Therefore, it is possible to reduce the waiting time that the AGV 55 waits to collect the feeder 24, and to efficiently collect the feeder 24 by the AGV 55.

[0030] Furthermore, since the AGV 55 starts traveling before the feeders 24 to be collected are all gathered in the storage 16 and waits at the standby position P2 until the feeders 24 are all gathered, the AGV 55 can be quickly moved to the storage 16 once the feeders 24 are all gathered and can perform the collection work. Furthermore, since the AGV 55 starts traveling when the collection ratio R of the feeders 24 becomes equal to or greater than the predetermined ratio Rref, the timing to start traveling can be appropriately determined by simple processing, and the standby time at the standby position P2 can be prevented from becoming long. Therefore, it is possible to prevent the AGV 55 waiting at the standby position P2 from obstructing the traveling of other AGVs 55.

[0031] It goes without saying that the present disclosure is not limited to the above-described embodiments, and can be implemented in various forms as long as they fall within the technical scope of the present disclosure.

[0032] For example, in the above-described embodiment, the transport control device 58 determines whether the AGV 55 has arrived at the standby position P2 based on the position information of the AGV 55 in S130, but the present invention is not limited to this. The transport control device 58 may predict the arrival timing at the standby position P2 based on the start timing of the AGV 55, the speed of the AGV 55, the distance to the standby position P2, etc., and determine whether the arrival timing has arrived in S130.

[0033] In the embodiment, the predetermined ratio Rref is set to a value smaller than 100%, but it may be set to 100% as described above. That is, the AGV 55 may be controlled so that it starts traveling from the travel start position P1 to the storage 16 when all the feeders 24 to be collected are present in the storage 16. This reliably reduces the waiting time required for the AGV 55 to wait for the feeders 24 to be collected into the storage 16 when the AGV 55 approaches the storage 16. Furthermore, by having the AGV 55 wait at the waiting position P2, it is possible to prevent interference with other AGVs 55.

[0034] In the embodiment, the predetermined rate Rref is a predetermined value (a fixed value). However, the present invention is not limited to this, and the predetermined rate Rref may be set by receiving input from an operator or the like. Alternatively, the transport control device 58 may be configured to set the predetermined rate Rref so that it decreases as the travel distance of the AGV 55 from the travel start position P1 to the destination storage 16 or the standby position P2 increases. In this way, the AGV 55 starts traveling earlier the longer the travel distance of the AGV 55. In other words, the travel start timing can be determined to reduce the time the AGV 55 waits at the standby position P2, thereby enabling the AGV 55 to more efficiently collect the feeders 24 while more reliably preventing interference with other AGVs 55.

[0035] In the embodiment, the case where the feeder 24 is retrieved from the storage 16 has been described as an example, but the present invention is not limited to this, and the delivery of the feeder 24 to the storage 16 and the retrieval of the feeder 24 from the storage 16 may be performed consecutively. Fig. 7 is a flowchart showing AGV travel control in a modified example, and Fig. 8 is an explanatory diagram showing the state in which the AGV 55 travels to the storage 16 in the modified example. In the modified example, the same processes as in the embodiment are assigned the same reference numerals, and descriptions thereof will be omitted.

[0036] In the modified example of FIG. 7, the transport control device 58 first determines whether all the feeders 24 to be distributed have been collected (S210). In S210, the transport control device 58 determines whether all the feeders 24 to be distributed are loaded onto the AGVs 55 in the warehouse 60 or nearby. Alternatively, the transport control device 58 may determine whether the AGVs 55 carrying all the feeders 24 to be distributed are ready to depart. If the transport control device 58 determines in S210 that all the feeders 24 to be distributed have been collected, it obtains the collection status of the feeders 24 in the storage warehouse 16 in S100 and determines whether the feeders 24 can be collected (S110b). For example, in S110b, it determines whether all the feeders 24 to be collected are collected in either the first storage unit 16a or the second storage unit 16b, i.e., whether the collection rate R is 100%. If the transport control device 58 determines in S110b that the item can be collected, it starts traveling of the AGV 55 to the storage shed 16 in S120.

[0037] In this modification, the AGV 55 starts traveling after determining in S110b that the feeder 24 can be collected. Therefore, when the AGV 55 arrives at the standby position P2 in S130, the transport control device 58 does not need to again acquire the collection status of the feeder 24 to determine whether collection is complete. Therefore, in S140b, the transport control device 58 acquires the evacuation status of the loader 18, and the process of S150 is omitted. Note that, even in this modification, the transport control device 58 may determine in S110b that the collection rate R is equal to or greater than the predetermined rate Rref, and the processes of S140 and S150 may be performed as in the embodiment. When the transport control device 58 determines in S160 that the loader 18 has been evacuated from the storage 16, the transport control device 58 first moves the AGV 55 in front of one of the storage units of the delivery destination (for example, the first storage unit 16a in FIG. 8) and executes the delivery operation of the feeder 24 (S175). Next, when the transport control device 58 determines that the serving work has been completed (S177), it moves the AGV 55 in front of the other storage unit (for example, the second storage unit 16b in Figure 8) from which the feeder 24 is to be collected, and performs the collection work.

[0038] 7, even if all the feeders 24 to be delivered are gathered, the AGV 55 is not immediately departed, but is departed only after it is confirmed that the feeder 24 to be retrieved is ready to be retrieved. Therefore, it is not necessary to wait until the AGV 55 arrives at the standby position P2 and is ready to retrieve the feeder 24. Furthermore, since the AGV 55 delivers and retrieves the feeders 24 continuously, it can be performed more efficiently with less movement loss than if the tasks were performed separately.

[0039] 9 also continuously delivers feeders 24 to the storage 16 and collects feeders 24 from the storage 16. In the modification of FIG. 9, the transport control device 58 first acquires the availability and collection status as the status of the feeders 24 in the storage 16 (S100b), and determines whether the feeders 24 to be delivered can be delivered and the feeders 24 to be collected can be collected (S110c). In S110c, it is determined whether one of the first storage section 16a and the second storage section 16b is available, and it is also determined whether the feeders 24 to be collected are available in the other of the first storage section 16a and the second storage section 16b, i.e., whether the collection ratio R is 100%. If the transport control device 58 determines in S110c that delivery and collection are possible, it starts the AGV 55 traveling to the storage 16 in S120. Since the subsequent processing is the same as that in FIG. 7, a description thereof will be omitted.

[0040] In this way, in the modified example of FIG. 9, the AGV 55 is departed only after it is confirmed that the feeder 24 to be collected can be collected and that the feeder 24 to be distributed can be distributed. Therefore, it is not necessary to wait for the AGV 55 to arrive at the standby position P2 until the feeder 24 is ready to be distributed or collected. Also, as in the modified example of FIG. 7, the feeder 24 can be continuously and efficiently distributed and collected. Note that in the modified example of FIG. 9, the determination in S210 may be performed before S100b, as in FIG. 7.

[0041] In the embodiment, the mounting system 1 (mounting line 10) is provided with the loader 18, but this is not limiting and the loader 18 may not be provided. For example, a worker may exchange the feeder 24 between the storage 16 and the mounting device 20 and retrieve the removed feeder 24 into the storage 16. Even in this case, the AGV 55 may need to wait until the feeder 24 to be retrieved is ready in the storage 16, and therefore, as in the embodiment, it is effective to control the travel of the AGV 55 based on the retrieval status.

[0042] In the embodiment, the components used in the mounting-related processes, such as the feeder 24, are transported by the AGV 55 to the dedicated storage 16 in the mounting line 10, but this is not limiting and the components may be transported to a predetermined location on the mounting line 10. For example, the components may be transported to a storage provided for each device (such as the printing device 12 or 14, the mounting device 20, or the mounting inspection device 28), such as a storage provided below the mounting device 20 in FIG.

[0043] Here, the mounting system of the present disclosure may be configured as follows. For example, in the mounting system of the present disclosure, the control device may control the automated guided vehicle to start traveling from a predetermined travel start position to the predetermined location when the components to be collected are gathered at the predetermined location. This prevents the automated guided vehicle from waiting to collect the components at the predetermined location when the automated guided vehicle arrives at or approaches the predetermined location, thereby reliably reducing waiting time. Furthermore, by having the automated guided vehicle wait near the predetermined location, interference between the waiting automated guided vehicle and other devices can be prevented.

[0044] In the mounting system of the present disclosure, the control device may control the automated guided vehicle to start traveling from a predetermined travel start position to the predetermined location before the components to be collected are gathered at the predetermined location, and to wait at a predetermined waiting position closer to the predetermined location than the travel start position until the components to be collected are gathered. In this way, once the components to be collected are gathered at the predetermined location, the automated guided vehicle can be quickly moved to the predetermined location, allowing the components to be collected more efficiently.

[0045] In the mounting system of the present disclosure, the control device may control the automated guided vehicle to start traveling from the travel start position when a predetermined percentage or more of the components to be collected have been collected before all of the components to be collected have been collected. In this way, the timing at which the automated guided vehicle starts traveling toward a predetermined location can be appropriately determined by simple processing, thereby preventing a long wait time at the standby position.

[0046] In the mounting system of the present disclosure, the predetermined location may include a collection location where the components are collected and a delivery location where the components are delivered. When the control device confirms that the components to be delivered have been collected based on the collection status of the components at the collection location, the control device controls the automated guided vehicle carrying the components to be delivered to start traveling from a predetermined travel start position to the predetermined location. At the predetermined location, the automated guided vehicle delivers the components to the delivery location and then retrieves the components from the collection location. This allows the automated guided vehicle to continuously deliver and retrieve components, thereby reducing travel loss compared to a vehicle that travels separately to deliver and retrieve components. This improves the efficiency of component collection and delivery.

[0047] In the mounting system of the present disclosure, the predetermined location may include a collection location where the components are collected and a delivery location where the components are delivered. The control device may control the automated guided vehicle, upon determining based on the collection status of the components at the collection location and the delivery status of the components at the delivery location that the components to be collected are available and that the components to be delivered can be delivered to the delivery location, to start traveling from a predetermined travel start position to the predetermined location. At the predetermined location, the automated guided vehicle delivers the components to the delivery location and then retrieves the components to be collected from the collection location. This allows the automated guided vehicle to continuously deliver and retrieve components, thereby reducing travel loss. Furthermore, when the automated guided vehicle arrives at or approaches the predetermined location, it does not need to wait for the components to be delivered or retrieved. This improves the efficiency of component collection and delivery. [Industrial Applicability]
