Description

Movement System and Transport Cart

[0001] Disclosed herein are a movement system and a transport cart.

[0002] Conventionally, as a mounting-related apparatus that performs a mounting process of placing components on a target object, for example, there has been proposed a printing apparatus including: a printing unit that performs a printing process of a viscous fluid on a processing target using a screen mask; and an exchange unit having a receiving section that receives a storage rack that stores a frame body capable of supporting exchangeable members related to the printing process performed by the printing unit (see, for example, Patent Document 1). In this mounting-related apparatus, exchangeable members can be exchanged more efficiently using the storage rack.

[0003] International Publication No. 2022 / 168145

[0004] By the way, in the mounting-related apparatus of the above-mentioned Patent Document 1, an automated guided vehicle may transport the storage rack, but in the transportation by the automated guided vehicle, it is sometimes difficult to finely adjust the position of the storage rack when delivering it to the exchange unit. In addition, if the storage rack is allowed to move for fine adjustment, it may move during automatic movement, which may hinder stable transportation.

[0005] The present disclosure has been made in view of such problems, and a main object thereof is to provide a movement system and a transport cart that can deliver and receive a storage rack more stably.

[0006] The movement system and the transport cart disclosed in the present specification adopt the following means to achieve the above-mentioned main object.

[0007] The movement system of the present disclosure is a movement system used in a mounting system including a mounting-related apparatus that performs a mounting process of placing components on a target object, the movement system comprising: a storage unit that accommodates mounting-related members and is delivered to a storage unit holding section provided in the mounting-related apparatus; and a transport cart that transfers the storage unit, the movement system further comprising: a movement support section that movably supports the storage unit on the transport cart within a predetermined clearance range.

[0008] In this transfer system, the storage unit can be moved within a clearance range on the transport trolley, so that when the storage unit is handed over to the storage unit holder, it moves and absorbs any misalignment of the storage unit. This transfer system allows for more stable handover of the storage unit.

Figure 7D shows the state after the movement restriction by the movable support section 67 has been released. In this embodiment, the left-right direction (X-axis), front-back direction (Y-axis), and up-down direction (Z-axis) are as shown in Figures 1 to 7. Note that the front and back of each device in the mounting system 10 and the front and back of the transport system 50 are opposite to each other because they face each other.

[0011] The mounting system 10 includes a printing device 11, a printing inspection device 12, a transport system 50 as a moving system, a storage device 14, a management device 13, a mounting device 15, a mounting inspection device 16, a loader 18, a reflow device (not shown), and a control device 19. The mounting system 10 is configured as a production line in which, for example, a mounting device 15 for mounting components P onto a substrate S (the target object) is arranged downstream of the printing device 11 in the transport direction of the substrate S. In the mounting system 10, mounting-related devices related to the mounting process include, for example, the printing device 11, a transport device for transporting the substrate S, a printing inspection device 12, a management device 13, a storage device 14, a mounting device 15, a mounting inspection device 16, a loader 18, a reflow device, and a control device 19. Examples of mounting-related components involved in the mounting process include, in addition to components P and substrates S, a screen mask M, a magazine containing the substrate S, a support member for supporting the substrate S, a feeder F as a supply device for supplying components P, a reel that holds components P and is attached to the feeder F, a tray on which components P are placed, a sampling member for collecting components P and a station containing it, and a mounting head on which the sampling member is attached.

[0012] The print inspection device 12 is a device that inspects the state of viscous fluids such as solder paste printed on the substrate S by the printing device 11. The transport system 50 is a device that automatically transports mounting-related materials between a preparation facility such as a warehouse for mounting-related materials and the mounting system 10. The management device 13 is configured as a server that manages the mounting system 10. The management device 13 exchanges information with each device included in the mounting system 10 and manages the usage status of mounting-related materials. The storage device 14 is a temporary storage location for feeders F that hold components P. The storage device 14 includes a container as a storage system that houses the feeders F to be used, and a container for collecting the feeders F after use. The mounting device 15 is a device that mounts components P onto the substrate S. The mounting device 15 includes a control device that controls the entire mounting device 15, a substrate processing unit that transports the substrate S, a component supply unit that supplies components P from the feeders F, and a mounting head equipped with a sampling member that collects components P. The mounting inspection device 16 is a device that inspects the condition of components P mounted on the substrate S. The loader 18 is configured as a mobile work device and moves left and right along the X-axis rail on the front side of the mounting device 15. The loader 18 is a device that automatically attaches, detaches, collects, and replenishes mounting-related components used in the mounting device 15, such as feeders F. The reflow device is a device that reflows the substrate S on which solder has been printed and components P have been placed. The control unit 19 is a device that manages information of each device in the mounting system 10 via a network such as the Internet. The control unit 19 exchanges information with, for example, one or more mounting systems 10 via a network and manages this information.

[0013] The printing apparatus 11 is a device that uses a squeegee 26 to press solder on a screen mask M into pattern holes formed in the screen mask M, thereby applying (printing) the solder, which is a viscous fluid, onto a substrate S, which is a target object below, through the pattern holes. Here, "target object" can be, for example, a substrate S on which components P are mounted, or a three-dimensional base material. "Viscous fluid" can be solder paste, conductive paste, or adhesive. As shown in Figure 1, the printing apparatus 11 comprises a control device 21, a substrate processing unit 22, a mask processing unit 23, a printing unit 24, a communication unit 27, an operation panel 28, a replacement unit 30, and a storage rack 40 as a storage unit. The control device 21 is configured as a microprocessor centered on a CPU as a control unit, and controls the entire printing apparatus 11. The control device 21 exchanges signals with each unit, as well as information with external devices such as a management device 13 and a control unit 19. The control device 21 includes a storage unit that stores print job information, including the conditions for executing the print job, and a print processing program that performs the print operation on the substrate S. The substrate processing unit 22 is located below the mask processing unit 23 and is a unit that loads the substrate S, positions and supports the loaded substrate S, and brings it into contact with and separates it from the screen mask M. A conveyor is provided in the substrate processing unit 22, and the substrate S is transported by this conveyor. The mask processing unit 23 is located between the printing unit 24 and the substrate processing unit 22 in the vertical direction and is a unit that fixes and holds the screen mask M. The printing unit 24 is a unit that prints a viscous fluid onto the substrate S using the screen mask M as part of the mounting process. The printing unit 24 includes a print head 25 equipped with a squeegee 26. The squeegee 26 is located on the lower side of the print head 25 and is raised and lowered by a squeegee lifting unit. The printing unit 24 has two squeegees 26, each used in the front-rear direction. The print head 25 is moved in the front-to-back direction of the device by the head moving unit during the printing process. The communication unit 27 is an interface for communication with external devices.The replacement unit 30 is a unit that automatically replaces mounting-related components used by the printing device 11, such as screen masks M, support members for substrates S, cleaning members for screen masks M, and viscous fluid cartridges. The replacement unit 30 is located on the left and right sides of the housing of the printing device 11, and receives a storage rack 40 in the receiving space formed between them, moving the storage rack 40 between the replacement position and the standby position. The storage rack 40 is a storage unit that houses mounting-related components. The storage rack 40 is equipped with casters and is moved by an operator W as well as by a transport system 50.

[0014] The control panel 28 has the functions of an operation unit that receives input from the operator W and a notification unit that notifies the operator W of information. The control panel 28 is located on the left front side of the housing of the printing device 11. The notification unit is, for example, a display that shows characters or icons, and may notify the status of the printing device 11 by the color of the characters or icons. The notification unit may also have a display unit that displays characters, symbols, etc., or it may have a speaker that outputs sound.

[0015] The exchange unit 30 is a unit configured as a storage unit holder that moves a storage rack 40, which is a storage unit that houses printing-related components used in the printing device 11, between a standby position and an exchange position, and automatically exchanges printing-related components between the storage rack 40 and the printing device 11. Printing-related components are included in mounting-related components and include, for example, a screen mask M, a support member that supports the substrate S, a cartridge containing a viscous fluid, and a cartridge containing a cleaning member for cleaning the screen mask M. This exchange unit 30 is provided on the left and right sides of the front of the housing of the printing device 11 and is composed of a first exchange section and a second exchange section. As shown in Figures 1 and 3, the exchange unit 30 includes a receiving section 31 and a component moving section 34. The receiving section 31 is configured to receive the storage rack 40 so that it can be raised and lowered, and is located between the first exchange section and the second exchange section. As shown in Figures 3C and 3D, the exchange unit 30 has a receiving section 31 with a clearance C between the first exchange section and the second exchange section, into which the storage rack 40 fits when it is transferred. The clearance C is provided in a direction along the X-axis, which is perpendicular to the direction of movement T along the Y-axis, in which the transport system 50 moves relative to the exchange unit 30. The receiving section 31 is composed of a rack support section 32, a rack movement section 33, and a guide section 35. The rack support section 32 is the part that supports the guide member 42 of the storage rack 40 from below. The rack support section 32 and the rack movement section 33 move the rack support section 32, which supports the storage rack 40, between a standby position inside the housing and an exchange position where printing-related components are transferred into the device (see Figures 10E and 10F described later). The component moving section 34 is equipped with a belt drive device. This belt drive device is inserted into through grooves formed on the left and right sides of the housing section 41 of the housing rack 40, and contacts the side of the frame on which the screen mask M is fixed, moving it along the direction of movement (Y-axis direction). The guide section 35 is a component that guides the housing rack 40, which may be transported by the transport system 50 and may be subject to displacement, into the interior of the replacement unit 30. The guide section 35 is shaped such that the replacement unit 30 is positioned in the housing position of the replacement unit 30 as the housing rack 40 enters the replacement unit 30.The storage rack 40 is handed over to the exchange unit 30 even if the transport system 50 is misaligned, as the guide member 42 is guided to the guide section 35. When the transport system 50 transports the storage rack 40, the exchange unit 30 moves the rack support section 32 to a predetermined receiving height H.

[0016] The storage rack 40 is a movable storage unit that houses frames holding printing-related components such as screen masks M and support blocks for supporting substrates S in a shelf-like manner. The storage rack 40 only houses the frames and does not have a drive unit to move the frames or a drive unit to raise and lower the frames, nor a power source to drive the drive unit. This storage rack 40 allows for a simpler configuration. As shown in Figures 2 and 3, the storage rack 40 houses printing-related components used in the mounting system 10 via a transport system 50 and is then transferred to the exchange unit 30 of the printing device 11. As shown in Figures 3 to 4 and 6 to 7, the storage rack 40 comprises a storage section 41, a guide member 42, a caster 43, a receiving member 45, a cam follower 47, and an engaging member 48. The storage rack 40 has multiple slots inside the storage section 41 into which frames holding screen masks M and support blocks are inserted. The guide member 42 is guided by contacting the guide portion 35 of the replacement unit 30 and is supported by the rack support portion 32 of the replacement unit 30. The guide member 42 is located at the lower part of both sides of the storage portion 41. The storage rack 40 has casters 43 and can be moved by an operator W using the handle, and can be moved when loaded onto a transport trolley 60, or an automated guided vehicle can move by entering the central space at the bottom.

[0017] The receiving member 45 has an inclined surface 46 on its lower side and is a member that guides the storage rack 40 to a predetermined position corresponding to the ideal center position of the exchange unit 30 by contact member 68 that abuts against the inclined surface 46. The receiving member 45 is disposed on the lower side of a support member whose longitudinal direction is horizontal and is located near the caster 43 below the storage section 41. As shown in Figure 6B, the inclined surface 46 is inclined toward the center so that the central part is recessed. A recess is formed in the center of the lower side of the inclined surface 46 into which a ball of the contact member 68 fits. As shown in Figures 7A and 7B, the cam follower 47 is a member that abuts against the guide plate 69 of the movable support section 67 of the transport trolley 60 when loading the storage rack 40 onto or unloading it from the transport trolley 60, and guides the storage rack 40 to move to an allowable position on the transport trolley 60. The engaging member 48 engages with the holding member 71 of the movement restricting section 70, which is located on the transport trolley 60. The engaging member 48 has an engaging hole 49 into which the holding member 71 is inserted. The engaging member 48 is located on a support member whose longitudinal direction is horizontal, which is located near the lower caster 43, and the engaging hole is also in communication with this support member.

[0018] As shown in Figures 1 to 7, the transport system 50 is configured as a moving system that automatically transports printing-related components used in the printing device 11 of the mounting system 10, such as screen masks M, between the exchange unit 30 of the printing device 11 and the preparation facility. As shown in Figure 4, the transport system 50 is composed of an automated guided vehicle 51, a connecting unit 55, and a transport trolley 60.

[0019] The automated guided vehicle (AGV) 51 is configured as, for example, an AGV (Automatic Guided Vehicle) or an AMR (Autonomous Mobile Robot). The AGV 51 moves in conjunction with a transport trolley 60. As shown in Figure 4, the AGV 51 includes a mounting unit 52, a power supply unit 53, a driving unit 54, and a control device (not shown). The mounting unit 52 is a mechanism for mounting and unmounting the coupling unit 55. The power supply unit 53 is a battery that supplies power to the entire transport system 50. Power supplied from this power supply unit 53 enables the driving of the driving unit 54, the control of the coupling unit 55, communication between the coupling unit 55 and the transport trolley 60, and the driving of the work devices 61 on the transport trolley 60. The driving unit 54 is the unit that drives the AGV 51 and includes drive wheels, driven wheels, and a drive motor. The drive motor drives the drive wheels and controls the direction of travel of the vehicle. The control device is a controller equipped with a control unit and a memory unit, and controls the entire system of the automated guided vehicle 51.

[0020] The coupling unit 55 is a unit that connects the automated guided vehicle 51 and the transport trolley 60. As shown in Figure 4, the coupling unit 55 is removably attached to the mounting part 52 of the automated guided vehicle 51. The coupling unit 55 may also be configured to be attached to the transport trolley 60 side. The coupling unit 55 comprises a coupling execution unit 56, a control unit 57, and a power communication unit 59. The coupling execution unit 56 is a unit that guides the coupling member 64, which is disposed on the underside of the work device 61 of the transport trolley 60, to a predetermined coupling position, and fixes and releases the coupling member 64 at the coupling position. The control unit 57 is a unit that includes an interface for controlling the entire transport system 50. The control unit 57 is disposed at the rear of the coupling unit 55. The control unit 57 has a control unit 58 with a memory unit and an operation panel. The control unit 58 is configured as a microprocessor centered on a CPU and is in charge of controlling the entire device. The memory unit stores information that controls the entire transport system 50, such as transport job information including information on printing-related components to be transported to the printing device 11, a transport program that executes the transport process, and a linking program that links the automated guided vehicle 51 and the transport trolley 60. The control unit 58 controls the movement restriction unit 70 to release the movement restriction of the transport trolley 60 before handing over the storage rack 40 to the exchange unit 30. The operation panel informs the worker W of the status of the transport system 50 and includes a display unit that displays information and an operation unit that receives input from the worker W. The power communication unit 59 is a unit that supplies power to the transport trolley 60 and performs communication. The power communication unit 59 includes a power unit that exchanges power and a communication unit that exchanges signals, but these may be an integrated unit or separate units. The power communication unit 59 may be a wired unit with a connector, or a wireless unit without a physical connection, and a wireless unit is preferred for ease of maintenance.

[0021] The transport cart 60 transports mounting-related components for the mounting process. The transport cart 60 is not self-propelled and is connected to an automated guided vehicle (AGV) 51. It receives power from the AGV 51 via a power communication unit 59 and moves automatically as the AGV moves. The transport cart 60 comprises a work device 61 and a cart section 62. The work device 61 is a device that performs predetermined tasks on mounting-related equipment. This work device 61 may, for example, be a loading device that includes a loading unit 65, transfers the storage racks 40, and hands over the storage racks 40 to the exchange unit 30. The loading unit 65 comprises a loading section 66, a movement support section 67, a movement restricting section 70, and a detection section 75. The loading section 66 is a platform on which the storage racks 40 are loaded. The loading section 66 has walls on its sides and front and rear to prevent the loaded items from falling.

[0022] The movable support section 67 supports the storage rack 40 so that it can move within a predetermined clearance range on the transport trolley 60. The predetermined clearance range includes, for example, a predetermined position where the storage rack 40 stops stably on the work device 61, and is a range that can move along the contact member 68, and may be within the range of the inclined surface 46 of the receiving member 45. Alternatively, the predetermined clearance range may be the range in which the storage rack 40 can move when it is received by the guide section 35 of the exchange unit 30, and may be a range based on the clearance C of the exchange unit 30, for example, a range that takes into account a margin in addition to the clearance C. This predetermined clearance range may be a range along a direction perpendicular to the movement direction T of the transport trolley 60, that is, along the width direction of the exchange unit 30. When the movement restricting section 70 is in a movement restricting state, the movable support section 67 holds the storage rack 40 immovably in a predetermined position, and when the movement restricting section 70 is released, it supports the storage rack 40 so that it can move within the predetermined clearance range. The movable support section 67 is positioned on the transport trolley 60 side and contacts the receiving member 45 of the storage rack 40 to support the storage rack 40 so that it can move upward. The movable support section 67 is composed of a contact member 68 and a guide plate 69. The contact member 68 and guide plate 69 may be positioned at three or more locations on the work device 61, but in this movable support section 67, they are positioned at four locations at the four corners of the rectangular work device 61. This movable support section 67 can support the storage rack 40 more stably. The contact member 68 contacts the receiving member 45, which guides the storage rack 40 to a predetermined position by an inclined surface 46, and the receiving member 45 guides the storage rack 40 to the predetermined position, supporting it so that it can move. The contact member 68 is not particularly limited as long as it can move the transport trolley 60 slightly and support the transport trolley 60, but for example, it may be a ball caster. The contact member 68 has a ball that is rotatably disposed at its upper part and contacts the receiving member 45 (see Figure 6). The ball of the ball caster contacts the inclined surface 46 of the receiving member 45. The guide plate 69 has a tapered surface on its upper tip side and is a member that contacts the cam follower 47 to guide the storage rack 40 to the appropriate loading position.The guide plate 69 has a guide surface that guides the cam follower 47, which is positioned along the X-axis, and moderately restricts the movement of the storage rack 40 in the front-to-back direction along the Y-axis (see Figure 7B).

[0023] As shown in Figure 7, the movement restriction unit 70 is a unit that restricts and releases the movement of the storage rack 40, which is movably supported by the movement support unit 67, at a predetermined position on the transport trolley 60. When the movement restriction is in place, the movement restriction unit 70 holds the storage rack 40 immovably at a predetermined position, and when the restriction is released, it allows the storage rack 40 to move within a predetermined clearance range. The movement restriction unit 70 is composed of a holding member 71, a biasing member 72, and a drive unit 73. The holding member 71 is disposed on the transport trolley 60, operates between a restricted position and a released position, and engages with an engaging member 48 disposed on the storage rack 40. The holding member 71 is a columnar holding pin inserted into an engaging hole 49 of the engaging member 48. The holding member 71 is biased to the restricted position by the biasing member 72 (Figure 7C). The holding member 71 is also driven by the drive unit 73 to move to the released position (Figure 7D). The biasing member 72 is a spring member that biases the holding member 71 to the restricted position. The drive unit 73 is a linear drive unit that moves the holding member 71 to the unrestricted position, for example, a solenoid or a linear motor. The drive unit 73 is driven by power supplied from the power supply device 53 via the power communication unit 59.

[0024] The detection unit 75 is a sensor that detects the storage racks 40 loaded on the work device 61. The detection unit 75 may be, for example, a contact-type sensor that contacts the storage racks 40 and outputs a signal, or a non-contact-type sensor that detects the storage racks 40 by irradiating and inputting detection light. Here, the detection unit 75 is configured as a contact-type sensor that outputs a detection signal when the storage racks 40 are pushed downward when they are loaded onto the work device 61 (see Figures 7A and 7B). The detection unit 75 operates by power supply from the power supply device 53 via the power communication unit 59.

[0025] The trolley section 62 has casters 63 and a connecting member 64. The trolley section 62 moves by supporting the work device 61 with the casters 63. The casters 63 are running wheels that do not have a drive unit. Four casters 63 are arranged on the trolley section 62. As shown in Figure 5, the trolley section 62 has a power communication unit 59, a power communication unit that provides power and communication, and a connecting member 64 on its underside. The connecting member 64 is a member that connects the automated guided vehicle 51 and the transport trolley 60 by being fixed in the connection position by the connection execution unit 56. The connecting member 64 may be, for example, a cylindrical member. The connecting member 64 is arranged facing downwards on the underside of the trolley section 62.

[0026] Next, an overview of the printing process of the printing apparatus 11 configured in this way will be described. When an execution command for production processing is input from the operator W, the control unit of the control device 21 starts the printing process routine. When this routine starts, the control unit transports and fixes the substrate S using the substrate processing unit 22, and adjusts the position of the screen mask M using the mask processing unit 23 based on the print job information to align the pattern holes with the substrate S. Subsequently, the control unit dispenses solder from the cartridge onto the screen mask M, moves the print head 25 and lowers the squeegee 26 to bring the squeegee 26 into contact with the upper surface of the screen mask M, and moves it in the back-and-forth direction to print the solder onto the substrate S. After printing, the control unit unloads the substrate S and repeats the above process until there are no more substrates S left. In the printing apparatus 11, for each production of substrate S, the screen mask M and support members are replaced by the replacement unit 30 using the storage rack 40. The transport system 50 moves the storage rack 40 between the preparation facility and the printing apparatus 11.

[0027] Next, the mounting process of the mounting device 15 will be described. When an execution command for production processing is input from the worker W, the control unit starts the mounting process routine. Once this routine starts, the control unit has the substrate processing unit transport and fix the substrate S. Next, the control unit has the mounting head pick up the components P to be picked up, which have been set based on the mounting job information, and place them on the substrate S. Once all the components P have been placed on the substrate S, the control unit has the substrate processing unit transport the substrate S and repeats the above process until the next substrate S is gone. In the mounting device 15, the loader 18 is used to automatically replace the feeder F and support members, etc., for each production of substrate S or based on the running out of components. The transport system 50 moves a container containing mounting machine-related components, including the feeder F and support members, between the preparation facility and the storage device 14.

[0028] Next, the operation of the printing device 11 and the transport system 50 will be described, in particular the process by which the transport system 50 transports the storage racks 40, the exchange unit 30 receives the storage racks 40, and the printing device 11 uses them. Figure 8 is a flowchart showing an example of a storage rack processing routine executed by the control device 21 of the printing device 11. Figure 9 is a flowchart showing an example of a storage rack transport processing routine executed by the control unit 58 of the transport system 50. Figure 10 is an explanatory diagram showing an example of the operation of receiving and using the storage racks 40, where Figure 10A shows the transport system 50 waiting in the receiving preparation position, Figure 10B shows the transport system 50 moving to the receiving position, Figure 10C shows the storage racks 40 being received, Figure 10D shows the transport system 50 moving to the retracted position, Figure 10E shows the storage racks 40 being moved to the waiting position, and Figure 10F shows the storage racks 40 being moved to the exchange position.

[0029] The storage rack processing routine is stored in the memory unit of the control device 21 and executed at a predetermined timing, such as after the execution of the mounting process has started. As preparation work, the worker W connects the automated guided vehicle 51 and the transport trolley 60 of the transport system 50 and loads the storage rack 40, which houses the frame holding the screen mask M, onto the work device 61. At this time, the storage rack 40 is guided by the cam follower 47 contacting the guide plate 69 (Figure 7B), the contact member 68 is guided to a predetermined position by the receiving member 45 (Figure 6B), and the holding member 71 is inserted into the engagement hole 49 to restrict the movement of the storage rack 40 at the predetermined position (Figure 7C). When this storage rack processing routine is executed, the control unit of the control device 21 first determines whether the exchange unit 30 is currently in a state to accept the storage rack 40 based on the print job and the state of the exchange unit 30 (S100). When receiving the storage rack 40, the control unit moves the rack support section 32 of the receiving section 31 to the receiving height H (S110, Figure 10A), sends a signal to the transport system 50, and moves the transport system 50, which is in the receiving preparation position, to the receiving position (S120, Figure 10B). When the control unit receives a signal from the transport system 50 indicating that the receiving position has been reached, it moves the rack support section 32 of the receiving section 31 to, for example, the maximum height and stops the rack support section 32 (S130, Figure 10C). At this time, the rack support section 32 supports the guide member 42 of the storage rack 40 from below, and the storage rack 40 is unloaded from the transport trolley 60. The exchange unit 30 also detects the acceptance of the storage rack 40 using a sensor (not shown) or the like, and outputs an acceptance completion signal to the transport system 50. Next, the control unit outputs a signal to the transport system 50, and moves the transport system 50 to the waiting position (S140, Figure 10D). Furthermore, the control unit lowers the storage rack 40 and moves it to the standby position (S150, Figure 10E). In this way, the transport system 50 hands over the storage rack 40 to the exchange unit 30.

[0030] On the other hand, if the storage rack 40 is not accepted in S100, the control unit determines whether or not to release the acceptance of the storage rack 40 (S160). When releasing the acceptance of the storage rack 40, the control unit moves the rack support portion 32 of the receiving unit 31 to, for example, its maximum height (S170), sends a signal to the transport system 50, and moves the transport system 50, which is in the acceptance preparation position, to the acceptance position (S180). Next, the control unit lowers the rack support portion 32 of the receiving unit 31 to hand over the storage rack 40 to the transport system 50 (S190). Next, the control unit sends a signal to the transport system 50, moves the transport system 50 to the retracted position (S200), and moves the rack support portion 32 of the receiving unit 31 to the standby position (S210). In this way, the exchange unit 30 hands over the storage rack 40 to the transport system 50.

[0031] After S210 or after S150, the control unit determines, based on the print job information, whether or not there is a replacement of printing-related components in the printing device 11 (S220). If there is a replacement of printing-related components, the control unit moves the storage rack 40 to the replacement position (S230, Figure 10F) and has the replacement unit 30 or the like perform the replacement of the printing-related components (S240). Then, when the replacement of the printing-related components is completed, the control unit moves the storage rack 40 to the standby position (S250, Figure 10E). The control device 21 of the printing device 11 repeatedly performs this process to continuously execute the printing process. On the other hand, if there is no replacement of printing-related components in S220, or after S250, the control unit determines whether or not the manufacturing of the substrate S is complete (S260). If the manufacturing of the substrate S is not complete, the process from S100 onwards is executed. On the other hand, if the manufacturing of the substrate S is completed in S260, this routine is terminated.

[0032] Next, the control of the transport system 50 will be described. The storage rack transport processing routine shown in Figure 9 is stored in the memory unit of the control unit 57 and is executed at a predetermined timing, such as after the execution of the mounting process has started. When this routine is started, the control unit 58 of the control unit 57 first moves the storage rack 40, loaded with the racks, to the receiving preparation position in front of the exchange unit 30 of the printing device 11, based on the transport job information (S300). Next, when the transport system 50 reaches the receiving preparation position, the control unit 58 moves the holding member 71 to the release position by the drive unit 73 to release the movement restriction of the movement restriction unit 70 (S310). At this time, the storage rack 40 is supported by the receiving member 45 and the contact member 68 so as to be movable within a predetermined clearance range on the work device 61. Next, when a movement signal is received from the printing device 11, the control unit 58 moves to the receiving position of the exchange unit 30 (S320). At this time, even if the automated guided vehicle 51 is misaligned, the storage rack 40 can move within a predetermined clearance range on the work device 61, so the guide member 42 is guided to the guide section 35, and the storage rack 40 can move smoothly to the receiving position (see Figures 3D, 6C, etc.). When the storage rack reaches the receiving position, the control unit 58 outputs an arrival signal to that effect (S330) and waits until it receives a receiving completion signal from the printing device 11 (S340). When it receives the receiving completion signal, the control unit 58 determines whether the detection of the storage rack 40 has been turned off based on the signal from the detection unit 75 (S350), and if the detection of the storage rack 40 has not been turned off, it outputs an error to that effect (S380). This routine ends. The error output may be displayed on the operation panel of the control unit 57, or it may be output to the printing device 11 and displayed on the operation panel 28 of the printing device 11, or it may be output to the management device 13 or the central control device 19. On the other hand, when the detection of the storage rack 40 is turned off in S350, the control unit 58 terminates the drive of the drive unit 73 and terminates the release of the movement restriction unit 70 (S360), and outputs a report to the printing device 11, management device 13, control unit 19, etc., indicating that the transport of the storage rack 40 is complete (S360).Then, the control unit 58 moves to a retracted position away from the exchange unit 30 and, based on the transport job information, moves to the next target position (S370), ending this routine. In this way, the transport system 50 makes the storage rack 40 movable by moving the holding member 71 of the movement restricting unit 70 to the release position when the storage rack 40 is being handed over, thereby further reducing the failure of the transfer of the storage rack 40 to the exchange unit 30, which may occur due to misalignment of the automated guided vehicle 51, etc.

[0033] Here, the correspondence between the components of this embodiment and the components of the present disclosure will be clarified. The implementation system 10 of this embodiment is an example of the implementation system of the present disclosure, the transport system 50 is an example of the transport system, the automated guided vehicle 51 is an example of the automated guided vehicle, the transport trolley 60 is an example of the transport trolley, the storage rack 40 is an example of the storage unit, the exchange unit 30 is an example of the storage unit holding part, and the movement support part 67 is an example of the movement support part. Furthermore, the movement restricting part 70 is an example of the movement restricting part, the contact member 68 is an example of the contact member, the receiving member 45 is an example of the receiving member, the inclined surface 46 is an example of the inclined surface, the holding member 71 is an example of the holding member, the engaging member 48 is an example of the engaging member, the control unit 58 is an example of the control unit, the guide part 35 is an example of the guide part, and the receiving part 31 is an example of the receiving part. Furthermore, component P is an example of a component, substrate S is an example of an object, screen mask M and feeder F are examples of mounting-related components, and printing device 11, printing inspection device 12, management device 13, storage device 14, mounting device 15, mounting inspection device 16, loader 18, control device 19, and transport system 50 are examples of mounting-related devices. In this embodiment, by describing the transport system 50, an example of the automated guided vehicle, transport trolley, and their control method of the disclosed herein is also revealed.

[0034] The transport system 50 described above, as a moving system, includes a storage rack 40 as a storage unit used in a mounting system 10 which includes a mounting-related device that performs a mounting process of placing components P onto a substrate S as an object, and which is handed over to a replacement unit 30 which is a storage unit holding part of the mounting-related device, and a transport trolley 60 for transferring the storage rack 40. This transport system 50 includes a movable support part 67 that supports the storage rack 40 so that it can move on the transport trolley 60 within a predetermined clearance range. In this transport system 50, since the storage rack 40 can move within the clearance range on the transport trolley 60, the storage rack 40 can move when handed over to the replacement unit 30, and the displacement of the storage rack 40 can be absorbed. With this transport system 50, the handover of the storage rack 40 can be performed more stably.

[0035] Furthermore, the transport system 50 includes a movable support unit 67 that supports the storage rack 40 so that it can move within a predetermined clearance range on the transport trolley 60, and a movable restricting unit 70 that restricts and releases the movement of the storage rack 40 at predetermined positions on the transport trolley 60. In this transport system 50, since the movement of the storage rack 40 is restricted on the transport trolley 60, the storage rack 40 can be transported stably by the transport trolley 60. Furthermore, the predetermined clearance range includes a predetermined position where the movement of the storage rack 40 is restricted, and is a range in which it can move along the contact member 68 provided by the movable support unit 67. When the movable restricting unit 70 is in the movement restricting state, the storage rack 40 is held immovably at the predetermined position, and when the movable restricting unit 70 is in the release state, the storage rack 40 can move within the predetermined clearance range. In this transport system 50, since the storage rack 40 can move within the clearance range on the transport trolley 60, the storage rack 40 can move when being handed over to the exchange unit 30, and any displacement of the storage rack 40 can be absorbed. Furthermore, since movement is restricted on the transport trolley 60, the storage rack 40 can be transported stably by the transport trolley 60.

[0036] Furthermore, in the transport system 50, the movable support unit 67 has a contact member 68 that abuts against a receiving member 45 which has an inclined surface 46 and guides the storage rack 40 to a predetermined position by the inclined surface 46, and guides the storage rack 40 to the predetermined position by the receiving member 45 and supports it so that it can move. In this transport system 50, the storage rack 40 can be supported so that it can move using the contact member 68. In addition, in this transport system 10, the storage rack 40 can be positioned using the receiving member 45 which has an inclined surface 46. Furthermore, in the transport system 50, the storage rack 40 is provided with a receiving member 45 which has an inclined surface 46 on its lower side and guides the storage rack 40 to a predetermined position by the inclined surface 46, and the movable support unit 67 is provided on the transport trolley 60 and abuts against the receiving member 45 to support the storage rack 40 so that it can move upward. In this transport system 50, the storage rack 40 can be supported and moved and positioned at a predetermined position by supporting the receiving member 45 with the movable support unit 67. Furthermore, the movement restriction unit 70 is disposed on the transport trolley 60 and operates between a restricted position and a release position. It has a holding member 71 that engages with an engaging member 48 disposed on the storage rack 40. Therefore, the holding member 71 engages with the engaging member 48 to restrict the movement of the storage rack 40. The transport system 50 is equipped with a control unit 58 that controls the movement restriction unit 70 to release the movement restriction before the storage rack 40 is handed over to the exchange unit 30. Thus, the movement restriction unit 70 restricts the movement of the storage rack 40 during transport, and releases the movement restriction when handing over the storage rack 40 to the exchange unit 30, thereby enabling a more stable handover of the storage rack 40. The exchange unit 30 is also equipped with a guide unit 35 that positions the storage rack 40 in the storage position of the exchange unit 30 so that the storage rack 40 fits into the exchange unit 30. The exchange unit 30 is provided with a clearance C into which the storage rack 40 fits when it is handed over. In this transport system 50, the storage rack 40, which has been moved by the transport trolley 60, can be positioned and transferred to the exchange unit 30 which has a clearance C by the guide unit 35.

[0037] Furthermore, since the transport cart 60 is connected to an automated guided vehicle 51 and is automatically moved by the automated guided vehicle 51, the transport system 50 can automatically move the transport cart 60 and the storage racks 40. In addition, the transport cart 60 receives power from the automated guided vehicle 51, and the movement restriction unit 70 is installed on the transport cart 60 and operates with this power supply. In this transport system 50, the configuration can be simplified by omitting the power source in the transport cart 60. Also, the movement restriction operation can be performed on the transport cart 60 that is supplied with power. Furthermore, since the storage racks 40 do not have a power source or drive source, the configuration of the storage racks 40 can be simplified. The exchange unit 30 is equipped with a receiving unit 31 that can receive the storage racks 40 so that they can be raised and lowered, and when the transport system 50 transports the storage racks 40, the receiving unit 31 moves to a predetermined receiving height H. In this transport system 50, automatic receiving of the storage racks 40 is possible.

[0038] It goes without saying that this disclosure is not limited in any way to the embodiments described above, and can be implemented in various forms as long as they fall within the technical scope of the present invention.

[0039] For example, in the above-described embodiment, the transport system 50 is provided with a movement restricting unit 70, but it is not limited to this, and the movement restricting unit 70 may be omitted. In this transport system 50, the storage rack 40 is not fixed while the transport trolley 60 is moving, but the transfer of the storage rack 40 to the exchange unit 30 can be performed more stably by the movement support unit 67. Alternatively, in this transport system 50, the transport system 50 is provided with a movement support unit 67, but it is not limited to this, and the movement support unit 67 may be omitted. In this transport system 50, the movement of the storage rack 40 while the transport trolley 60 is moving can be further suppressed, thereby enabling more stable movement of the storage rack 40.

[0040] In the embodiment described above, the receiving member 45 is disposed on the storage rack 40 side and the movable support part 67 is disposed on the transport trolley 60 side, but the system is not limited to this. Figure 11 is an explanatory diagram showing an example of another movable support part 67B and receiving member 45B. The movable support part 67B is disposed at the bottom of the storage rack 40. The receiving member 45B is disposed on the upper side of the work device 61 of the transport trolley 60. In this transport system 50, the transport trolley 60 is equipped with a receiving member 45B which has an inclined surface 46 on its upper side and guides the storage rack 40 to a predetermined position by the inclined surface 46, and the movable support part 67B is disposed on the storage rack 40 and abuts against the receiving member 45B to support the storage rack 40 so that it can move below it. In this transport system as well, since the storage rack 40 is supported so that it can move by the movable support part 67B, the transfer of the storage rack 40 to the exchange unit 30 can be performed more stably. Furthermore, in this transport system 50, the receiving member 45B supports the movable support section 67B, thereby enabling the storage rack 40 to be supported, moved, and positioned at a predetermined location.

[0041] In the above-described embodiment, the engaging member 48 is disposed on the storage rack 40 side and the holding member 71 of the movement restricting unit 70 is disposed on the transport trolley 60 side, but the system is not limited to this. Figure 12 is an explanatory diagram showing an example of another movement restricting unit 70B and engaging member 48B. The movement restricting unit 70B is disposed at the bottom of the storage rack 40. The engaging member 48B is disposed on the upper side of the work device 61 of the transport trolley 60. This movement restricting unit 70B is disposed on the storage rack 40 and has a holding member 71 that operates between a restricted position and an unrestricted position and engages with the engaging member 48B disposed on the transport trolley 60. In this transport system 50 as well, the movement of the storage rack 40 is restricted by the movement restricting unit 70B, so that the transfer of the storage rack 40 to the exchange unit 30 can be performed more stably.

[0042] In the embodiment described above, the receiving member 45 is described as having the inclined surface 46 that guides to a predetermined position. However, the present invention is not particularly limited thereto, and the receiving member 45 may not have the inclined surface 46. Even in this transport system 50, the moving support portion 67 still enables more stable delivery of the storage rack 40. In the transport system 50 including the receiving member 45 without the inclined surface 46, for example, an inclined surface may be formed on the engagement hole 49 of the engagement member 48. In the transport system 50, for inserting the holding member 71 into the engagement hole 49, it is preferable that the storage rack 40 is positioned at a predetermined position, and the inclined surface of the engagement hole 49 facilitates insertion of the holding member 71 into the engagement hole 49.

[0043] In the embodiment described above, the transport carriage 60 is described as receiving power supply from the automatic guided vehicle 51. However, the present invention is not particularly limited thereto, and the transport carriage 60 may have a power supply device. In addition, the storage rack 40 is described as having no drive source and power source. However, the present invention is not particularly limited thereto, and the storage rack 40 may have a drive source and / or a power source.

[0044] In the embodiment described above, when the transport system 50 transports the storage rack 40 to the receiving preparation position, the replacement unit 30 is described as moving the rack support portion 32 of the receiving portion 31 to the receiving height H. However, the present invention is not particularly limited thereto, and the receiving portion 31 may be set to another height, or this process may be omitted. Even in this transport system 50, since the storage rack 40 is movably supported by the moving support portion 67, delivery of the storage rack 40 to the replacement unit 30 can be performed more stably.

[0045] In the embodiment described above, the accommodation unit is the accommodation rack 40 that accommodates printing-related members such as a screen mask M. However, the configuration is not particularly limited to this as long as it conveys mounting-related members. For example, the conveyance carriage 60 may convey a container 40B that accommodates feeders F as the accommodation unit. Figure 13 is an explanatory diagram showing an example of another conveyance system 50B. In this conveyance system 50, a working device 61 of the conveyance carriage 60 loads the container 40B that accommodates feeders F. Also in this conveyance system 50, since the container 40B is movably supported by the movable support part 67, delivery of the accommodation rack 40 to the exchange unit 30 can be performed more stably.

[0046] In addition, in the embodiment described above, the present disclosure has been described as applied to the forms of an automated guided vehicle 51, a conveyance carriage 60, and a conveyance system 50, but the present disclosure may be configured as the conveyance carriage 60, may be configured as a control method for the conveyance system 50, or may be configured as a program that causes a computer to execute each step of this control method.

[0047] Here, the moving system and the conveyance carriage of the present disclosure may be configured as follows. For example, the moving system of the present disclosure is a moving system that is used in a mounting system including a mounting-related device that performs a mounting process of placing components on an object, the moving system comprising: an accommodation unit that accommodates mounting-related members and is delivered to an accommodation unit holding part included in the mounting-related device; and a conveyance carriage that transfers the accommodation unit, wherein the moving system further comprises: a movement restriction part that restricts movement of the accommodation unit at a predetermined position on the conveyance carriage and releases the movement restriction.

[0048] In this moving system, since movement of the accommodation unit is restricted on the conveyance carriage, the accommodation unit can be stably conveyed by the conveyance carriage. In this moving system, delivery of the accommodation unit can be performed more stably.

[0049] The transport trolley of this disclosure is a transport trolley that transports a housing unit, which is used in a mounting system including a mounting-related device that performs a mounting process of placing parts onto an object, and which is used to transport a housing unit that is handed over to a housing unit holding part of the mounting-related device, and comprises a movement restricting part that restricts and releases the movement of the housing unit at a predetermined position on the transport trolley, and a movement support part that supports the housing unit so that it can move within a predetermined clearance range on the transport trolley, wherein the predetermined clearance range includes the predetermined position and is a range that can move along a contact member provided by the movement support part, and when the movement restricting part is in a movement restricting state the housing unit is held immovably at the predetermined position, and when the movement restricting part is in an unrestricted state the housing unit can move within the predetermined clearance range.

[0050] This transport trolley, like the moving system described above, can more stably transfer the storage units. This transport trolley may incorporate any of the configurations of the moving system described above.
