[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 above-mentioned mounting system is configured to collect used components in a predetermined location and have the components collected from the predetermined location by an automatic guided vehicle. However, if the automatic guided vehicle arrives at the predetermined location and the components are not collected as scheduled, the automatic guided vehicle must wait until the components are collected, which reduces the efficiency of collecting the components by the guided vehicle.

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

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

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

[0008] In the mounting system of the present disclosure, the travel of the automated guided vehicle to a predetermined location is controlled based on the recovery status of the parts at the predetermined location. This makes it possible to prevent the automated guided vehicle from arriving at or approaching the predetermined location without completing the recovery of the parts. This reduces the waiting time that the automated guided vehicle waits to recover the parts at the predetermined location, allowing the automated guided vehicle to efficiently recover the parts.

[0010] Next, an embodiment for carrying out 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 automated 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. Furthermore, the mounting line 10 of this embodiment 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 on the board S (see FIG. 3) by pushing the solder into pattern holes formed in a screen mask. The print 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 board S by the mounting device 20. The reflow device 30 melts the solder by heating the board S on which the components are placed on the solder, and then cools it to electrically connect and fix each component on the board S. The reflow inspection device 32 inspects the state 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 and mounts them on the board S using a mounting head equipped with a picking member such as a nozzle. 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 components by rotating the reel and feeding the tape.

[0015] The loader 18 is configured to be movable within a movement area (dotted area in FIG. 1) along the transport direction of the substrate S, in front of the multiple mounting devices 20 and the storage 16. The loader 18 moves within the movement area to perform an automatic replacement operation of automatically replacing (collecting or replenishing) members 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 members used in the mounting-related process, such as the head, nozzle and other collection members, solder containing members, screen masks, etc., that are provided in the mounting unit 22.

[0016] The storage 16 is an in-line storage that stores various members used in the mounting-related processes in each mounting line 10, and stores, for example, the feeders 24. In the storage 16, the worker M can supply (refill) and recover the feeders 24. In addition, the loader 18 can automatically exchange the feeders 24 with respect to the storage 16, and removes the necessary feeders 24 from the storage 16 and refills them to the mounting device 20, or removes the used feeders 24 from the mounting device 20 and recovers them in the storage 16. In addition, in the storage 16, the AGV 55 can also refill and recover the feeders 24. In addition, the storage 16 is partitioned into a plurality of storage sections, such as a first storage section 16a and a second storage section 16b, and the 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 a 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 board S and production information related to the production of the board S. The production plan specifies the order in which components are mounted on the board S, the number of boards S to be produced, etc. The production information includes information indicating the printing position of solder on the board S, information on the components to be mounted on the board 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 arrangement status of the feeders 24 in each mounting device 20 and the storage 16 as the inventory status of components. When producing the board S, the mounting control device 38 gives various command signals to the printing device 12, the print 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 production information. The mounting control device 38 is also communicably connected to the transport control device 58, and exchanges information regarding the work status of the loader 18, information regarding the traveling status of the AGV 55, and the like.

[0018] Although not shown, the AGV 55 includes a motor for rotating wheels and a battery for supplying power, and automatically transports members 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 while the AGV 55 automatically transports the feeders 24, it is sufficient that the AGV 55 automatically transports members used in mounting-related processes, such as collection members such as a head and a nozzle provided in the mounting unit 22, solder accommodation members, and a screen mask.

[0019] Here, between the AGV 55 and the storage 16, for example, when a plurality of feeders 24 are mounted on a magazine 55a as a predetermined mounting member, the magazine 55a can be automatically exchanged as a whole. When one of the first storage section 16a and the second storage section 16b of the storage 16 is empty, the loader 18 takes the feeder 24 in and out of the other storage section, and recovers the used feeder 24 to the other storage section. When distributing and recovering the feeder 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 distributes 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 together with the magazine 55a. The AGV 55 automatically transports the collected feeder 24 to the warehouse 60.

[0020] In the warehouse 60, various materials such as the feeders 24 housed by the worker M and the feeders 24 automatically transported by the AGV 55 are stored. The AGV 55 can take multiple feeders 24 together with the magazine 55a into and out of the warehouse 60 at once. The charging station 57 is a facility for charging the batteries of one or multiple AGVs 55 parked at a predetermined charging position. The charging station 57 may be configured so that when the AGV 55 is parked at the predetermined charging position, a connector is connected to enable power supply, or it 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 a 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 obtains position information of the AGV 55, controls the travel of the AGV 55, such as departure and waiting, and obtains 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.

[0022] The management device 5 is a general-purpose computer including a CPU, a ROM, a RAM, a 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 the transport control device 58 of each mounting line 10. The management device 5 transmits production plans and production information of the boards S of each mounting line 10 to each mounting control device 38. The management device 5 receives, from each mounting control device 38, information on the production status of the boards S, the usage status of the feeders 24 required for production, the arrangement status of the feeders 24 in the storage 16, and the like. The production status includes the status of changeovers, such as replacement of a screen mask or replacement of the feeders 24, in preparation for production of a different type of board. The management device 5 also transmits a travel plan (transport plan) of each AGV 55 to the transport control device 58, and receives information on the travel status, remaining battery charge, charging status, and the like of each AGV 55 from the transport control device 58. In addition, 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 plans and production status of the boards S for each mounting line 10, information on the feeders 24 required for production, etc.

[0023] We will now explain the operation of the mounting system 1 thus configured, in particular the travel control of the AGV 55. Fig. 5 is a flow chart 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 transport control device 58 acquires the collection status of the feeder 24 in the storage 16 by communicating with the mounting control device 38 (S100), and judges whether the collection ratio R is equal to or greater than a predetermined ratio Rref (S110). The collection ratio 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), that is, the ratio of the number of collected feeders to the number of feeders scheduled to be collected. For example, the predetermined ratio Rref in this embodiment is preset to a value such as 80% that is smaller than 100%. Note that the predetermined ratio Rref may be set to 100%, and it may be judged in S110 whether collection is complete. In addition, the result of the judgment made by the mounting control device 38 in S110 may be transmitted as the collection status of the feeder 24 in S100. When the transport 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 facility 16, which is the destination (S120).

[0025] Then, the transport 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 the AGV 55 waits. When the transport control device 58 determines that the AGV 55 has arrived at the standby position P2, it acquires the recovery status of the feeder 24 in the storage 16 and the evacuation status of the loader 18 by communicating with the mounting control device 38 (S140). Note that the recovery status indicates the ratio in the storage section (the first storage section 16a or the second storage section 16b) of the recovery destination, as in S100. Next, the transport control device 58 determines whether the recovery of the feeder 24 is completed, that is, whether the recovery ratio R has reached 100% (S150), and whether the loader 18 has evacuated from in front of the storage 16 (S160). When 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 facility 16. Alternatively, the mounting control device 38 may suspend the operation of the loader 18 and move the loader 18 away from in front of the storage facility 16 before the AGV 55 arrives at the standby position P2 by communicating with the transport control device 58.

[0026] When the transport control device 58 determines in S150 that the collection of the feeder 24 has not been completed, or determines in S160 that the loader 18 has not been evacuated from in front of the storage 16, it outputs a standby instruction to the AGV 55 to wait at the standby position P2 (S170), and repeats the processes of S140 to S160. That is, the transport control device 58 waits for the collection of the feeder 24 in the storage 16 to be completed and the loader 18 to be evacuated, while making the AGV 55 wait at the standby position P2. Note that the transport control device 58 may first perform the process of S170 to make the AGV 55 wait at the 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 recovery of the feeder 24 to the storage 16 is completed and the loader 18 is retreated, the transport control device 58 moves the AGV 55 to the front of the storage unit of the recovery destination (for example, the first storage unit 16a in FIG. 6) to perform the recovery work of the feeder 24 (S180). Next, the transport control device 58 waits for the recovery work of the feeder 24 by the AGV 55 to be completed (S190), and when it determines that the recovery work is completed, the transport control device 58 starts the travel of the AGV 55 with the warehouse 60 as the destination (S200), recovers 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 included in 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 notice to the mounting control device 38. The mounting control device 38, which has received the work completion notice, 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 a mounting line, the AGV 55 corresponds to an automatic guided vehicle, and the transport control device 58 corresponds to a 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 during which the AGV 55 waits for collection of the feeder 24, and to efficiently collect the feeder 24 by the AGV 55.

[0030] In addition, the AGV 55 starts traveling before the feeders 24 to be collected are all present in the storage 16, and waits at the standby position P2 until the feeders 24 are all present, so that once the feeders 24 are all present, the AGV 55 can be quickly moved to the storage 16 to perform the collection operation. In addition, the AGV 55 starts traveling when the collection ratio R of the feeders 24 becomes equal to or greater than a predetermined ratio Rref, so that 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. This makes it 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 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.

[0032] For example, in the above 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 travel 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 may be set to 100% as described above. That is, the AGV 55 may be controlled so as to start traveling from the travel start position P1 to the storage 16 when the feeders 24 to be collected are all present in the storage 16. In this way, when the AGV 55 approaches the storage 16, the waiting time for waiting for the feeders 24 to be collected into the storage 16 can be reliably reduced. Also, by having the AGV 55 wait at the waiting position P2, interference with other AGVs 55 can be prevented.

[0034] In the embodiment, the predetermined ratio Rref is a predetermined value (fixed value), but it is not limited thereto, and may be set by receiving an input of the predetermined ratio Rref from an operator or the like. Alternatively, the transport control device 58 may be able to set the predetermined ratio Rref so that it tends to become smaller as the travel distance of the AGV 55 from the travel start position P1 to the destination, the storage 16 or the waiting position P2, becomes longer. In this way, the AGV 55 starts traveling earlier as the travel distance of the AGV 55 becomes longer. In other words, the travel start timing can be determined so as to reduce the time that the AGV 55 waits at the waiting position P2, and therefore the AGV 55 can more efficiently collect the feeder 24 while more reliably preventing interference between the AGV 55 and 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 the AGV travel control of the modified example, and Fig. 8 is an explanatory diagram showing the manner in which the AGV 55 travels to the storage 16 in the modified example. In the modified example, the same processes as those in the embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

[0036] In the modified example of FIG. 7, the transport control device 58 first determines whether the feeders 24 to be distributed are all ready (S210). In S210, the transport control device 58 may determine whether all the feeders 24 to be distributed are mounted on the AGV 55 in the warehouse 60 or in its vicinity. The transport control device 58 may also determine whether the AGV 55 on which all the feeders 24 to be distributed are mounted is ready to depart. When the transport control device 58 determines in S210 that the feeders 24 to be distributed are all ready, it obtains the collection status of the feeders 24 in the storage 16 in S100 and determines whether the feeders 24 can be collected (S110b). For example, in S110b, it is determined whether the feeders 24 to be collected are all ready in either the first storage unit 16a or the second storage unit 16b, that is, whether the collection ratio R is 100%. When the transport control device 58 determines in S110b that the item can be collected, it starts traveling of the AGV 55 to the storage facility 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 waiting position P2 in S130, the transport control device 58 does not need to obtain the collection status of the feeder 24 again to determine the completion of collection, and therefore obtains the evacuation status of the loader 18 in S140b and omits the process of S150. Note that, in the modification, the transport control device 58 may also perform the processes of S140 and S150 as in the embodiment, determining in S110b that the collection ratio R is equal to or greater than the predetermined ratio Rref. 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 (for example, the first storage unit 16a in FIG. 8) of the delivery destination to execute the delivery work of the feeder 24 (S175). Next, when the transport control device 58 determines that the meal distribution work is completed (S177), it moves the AGV 55 in front of the other storage unit of the collection destination (for example, the second storage unit 16b in FIG. 8) to perform the collection work of the feeder 24.

[0038] 7, even if all the feeders 24 to be distributed are ready, the AGV 55 is not departed immediately, but is departed after confirming that the feeders 24 to be collected are available. Therefore, it is not necessary to wait until the feeders 24 are available for collection after the AGV 55 arrives at the standby position P2. In addition, since the AGV 55 continuously distributes and collects the feeders 24, it is possible to reduce movement loss and perform the operations more efficiently than if they were performed separately.

[0039] In the modified example of FIG. 9, the feeder 24 is continuously delivered to the storage 16 and collected from the storage 16. In the modified example of FIG. 9, the transport control device 58 first acquires the availability status and the collection status as the status of the feeder 24 in the storage 16 (S100b), and judges whether the feeder 24 to be delivered can be delivered and the feeder 24 to be collected can be collected (S110c). In S110c, it is judged whether one of the first storage section 16a and the second storage section 16b is available, and it is judged whether the feeder 24 to be collected is available in the other of the first storage section 16a and the second storage section 16b, that is, whether the collection ratio R is 100%. When the transport control device 58 judges in S110c that the feeder 24 can be delivered and collected, it starts the travel of the AGV 55 to the storage 16 in S120. Since the same processing as in FIG. 7 is performed thereafter, the description is omitted.

[0040] In this way, in the modified example of FIG. 9, the AGV 55 is departed 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 until the feeder 24 is in a state where it can be distributed or collected after the AGV 55 arrives at the standby position P2. 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 judgment of S210 may be performed before S100b, as in FIG. 7.

[0041] In the embodiment, the mounting system 1 (mounting line 10) includes the loader 18, but this is not limiting and the loader 18 may not be included. For example, a worker may exchange the feeder 24 between the storage 16 and the mounting device 20, and retrieve the removed feeder 24 to the storage 16. Even in this case, it may be necessary to have the AGV 55 wait in order to wait for the feeder 24 to be retrieved to be ready in the storage 16, and so there is an effect of controlling the travel of the AGV 55 based on the retrieval situation as in the embodiment.

[0042] In the embodiment, the members used in the mounting-related processes, such as the feeder 24, are transported by the AGV 55 to the dedicated storehouse 16 in the mounting line 10, but the present invention is not limited to this and may be transported to a predetermined location on the mounting line 10. For example, the members may be transported to a storehouse provided in each device (printing device 12, printing device 14, mounting device 20, mounting inspection device 28, etc.), such as a storehouse 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 all present at the predetermined location. In this way, when the automated guided vehicle arrives at or approaches the predetermined location, it is possible to prevent the automated guided vehicle from waiting to collect the components at the predetermined location, thereby reliably reducing the waiting time. Furthermore, by having the automated guided vehicle wait near the predetermined location, it is possible to prevent interference between the waiting automated guided vehicle and other devices.

[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, when the components to be collected are gathered at the predetermined location, the automated guided vehicle can be quickly moved to the predetermined location, so that the components can 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 are collected before all of the components to be collected are 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, so that a long waiting time at the waiting position can be prevented.

[0046] In the mounting system of the present disclosure, the predetermined location may include a collection location where the components are collected and a distribution location where the components are distributed, and the control device may control the automatic guided vehicle so that when the components to be distributed to the distribution location are all ready and the control device confirms that the components to be collected have all been collected based on the collection status of the components at the collection location, the automatic guided vehicle on which the components to be distributed are mounted starts traveling from a predetermined travel start position to the predetermined location, and after distributing the components to be distributed to the distribution location at the predetermined location, the automatic guided vehicle collects the components to be collected from the collection location. In this way, the automatic guided vehicle can continuously distribute and collect the components, so that the movement loss can be reduced compared to a vehicle that moves to distribute and collect the components separately. Therefore, the efficiency of collecting and distributing the components can be improved.

[0047] In the mounting system of the present disclosure, the predetermined location includes a collection location where the components are collected and a distribution location where the components are distributed, and the control device may control the automatic guided vehicle so that when it is confirmed that the components to be collected are ready and the components to be distributed can be distributed to the distribution location based on the collection status of the components at the collection location and the distribution status of the components at the distribution location, the automatic guided vehicle on which the components to be distributed are mounted starts traveling from a predetermined travel start position to the predetermined location, and after distributing the components to be distributed to the distribution location at the predetermined location, the automatic guided vehicle collects the components to be collected from the collection location. In this way, the automatic guided vehicle can continuously distribute and collect the components, thereby reducing movement loss. In addition, when the automatic guided vehicle arrives at or approaches the predetermined location, it is not necessary to wait for the components to be distributed or collected. Therefore, the efficiency of collection and distribution of the components can be improved. [Industrial Applicability]
