Abstract
Description
Technical Field
[0001] This manual relates to a feeder storage system for storing component feeders that are equipped in a replaceable manner on a component mounting machine. Background Technology
[0002] The technology of mass-producing substrate products by performing substrate processing on substrates with circuit patterns is becoming increasingly widespread. As a representative example of substrate processing machines, there are component mounting machines that mount components onto substrates. Many component mounting machines use belt feeders, which use carrier belts to supply components. These belt feeders are stored in a larger quantity than are equipped on the component mounting machines, requiring operators to perform handling, preparation, and replacement operations. In recent years, in response to the demand for labor-saving methods, systems have been developed that automate at least some of these operations. In addition to belt feeders, component feeders that supply components also include disc feeders, rod feeders, etc. Patent Document 1 discloses a technical example aimed at automating and saving labor in the storage of component feeders.
[0003] In the warehouse system disclosed in Patent Document 1, a handling robot moves between a component receiving container warehouse, a component supply unit warehouse, and a component receiving container loader, transporting component receiving containers (e.g., reels with carrier belts wound around them) and component supply units (e.g., belt feeders) to the component receiving container loader, which then loads the component receiving containers into the component supply units. This automatically completes the preparation of the component supply units used in the component mounting machine, achieving further labor savings compared to previous methods.

[0007] The technical problem that the invention aims to solve
[0008] However, not limited to the technical example in Patent Document 1, fully automating the storage of component feeders is technically challenging. Currently, storage-related tasks are shared by devices (such as handling robots) and operators. In this situation, where the tasks of the devices and operators overlap, one party experiences waiting time, leading to reduced work efficiency.
[0009] Therefore, the technical problem to be solved in this specification is to provide a feeder storage system that can reduce the chance of overlap between the device and the operator's work related to the component feeder and suppress the reduction of work efficiency.

[0012] Additionally, this specification discloses a feeder storage system comprising: one or more storage compartments having multiple storage locations capable of storing multiple component feeders, the multiple component feeders being interchangeably mounted on a component mounting machine and supplying components; a transfer area arranged alongside the storage compartments for transferring the component feeders to a transport device that moves them toward the component mounting machine; a setting unit that designates a portion of the storage compartments or storage locations near the transfer area as a storage area for storing the multiple component feeders, and designates the remaining portion of the storage compartments or storage locations away from the transfer area as a work area for an operator to perform predetermined operations related to the component feeders; and a transfer device that transfers the component feeders between the storage area, the transfer area, and the work area.

[0014] Invention Effects
[0015] In the open feeder storage system, the handover area for the transfer of component feeders by the conveying device and the work area for the operator to perform the scheduled work are separated by the storage area. As a result, the movement paths of the conveying device and the operator are separated, the work does not overlap, the chance of overlap between the conveying device and the operator's work is reduced, and the decline in work efficiency is suppressed.

[0026] 1. Structural example of component mounting machine 9
[0027] The feeder storage system 1 of the embodiment stores the belt feeders (8A, 8B, 8C, 8D) that are detachably mounted on the component mounting machine 9. First, the structure of the component mounting machine 9 and the belt feeder 8A will be described. Figure 1 The component mounting machine 9 shown performs a mounting operation to mount components onto the substrate K. From Figure 1 The horizontal direction from the left side of the paper to the right is the X-axis direction for transporting the substrate K, the horizontal direction from the bottom (front) side of the paper to the top (back) side of the paper is the Y-axis direction, and the vertical direction is the Z-axis direction. The component mounting machine 9 is constructed by assembling the substrate transport device 92, the component supply device 93, the component transfer device 94, and the control device (not shown) on the base 91.
[0028] The substrate transport device 92 comprises a pair of guide rails 921, a pair of transport belts (not shown), and a clamping mechanism 922. The pair of guide rails 921 extend transversely through the center of the upper surface of the base 91 along the X-axis and are assembled parallel to each other on the base 91. The pair of transport belts rotate along the guide rails 921 with the substrate K placed on both parallel sides, transporting the substrate K to a stop position near the center of the base 91. The clamping mechanism 922 is positioned below the stop position, pushing the substrate K upwards to clamp and position it between itself and the guide rails 921. After the component mounting operation performed by the component transfer device 94 is completed, the clamping mechanism 922 releases the substrate K, and the transport belts move the substrate K out of the machine.
[0029] The component supply device 93 is located at the front of the upper surface of the base 91 in the Y-axis direction. The component supply device 93 consists of a tray table 931 and multiple belt feeders (8A, 8B), etc. The tray table 931 is generally rectangular when viewed from above and has multiple slots 932 that are separated from each other and extend parallel to each other in the Y-axis direction. The multiple belt feeders (8A, 8B) are respectively installed by being detachably inserted into the slots 932. The tray table 931 can also be detached from the base 91.
[0030] Belt feeders (8A, 8B, 8C, 8D) exist in multiple models (see reference). Figure 6 In this embodiment, four types of feeders described below are used. The first type's belt feeder 8A is a thin type with a small width dimension in the X-axis direction and is mounted in one slot 932. The second type's belt feeder 8B has a width dimension in the X-axis direction approximately twice that of the first type's belt feeder 8A and is mounted across two slots 932. The third type's belt feeder 8C has a width dimension in the X-axis direction approximately three times that of the first type's belt feeder 8A and is mounted across three slots 932. The fourth type's belt feeder 8D is an older type with the same width dimension in the X-axis direction as the first type's belt feeder 8A, but with a slightly different internal structure, and is mounted in one slot 932.
[0031] The component transfer device 94 comprises a Y-axis moving body 941, an X-axis moving body 942, a mounting head 943, a nozzle tool 944, multiple nozzles 95 (component mounting parts), a substrate camera 946, and a component camera 947. The Y-axis moving body 941 and the X-axis moving body 942 constitute an XY drive mechanism that moves the mounting head 943 in two horizontal directions. A rotationally symmetrical nozzle tool 944 is provided on the underside of the mounting head 943. Multiple nozzle tools 944 are provided in a manner that allows for automatic replacement. Figure 1 (In this example, there are 20) suction nozzles 95. The suction nozzles 95 perform a mounting operation that picks up components supplied from the belt feeders (8A, 8B, 8C, 8D) and mounts them onto the substrate K at the stop position. Furthermore, the mounting head 943 can also arrange multiple suction nozzles 95 in a row or in a grid pattern. Additionally, component mounting components other than the suction nozzles 95, such as component-holding clamps, can be automatically replaced on the mounting head 943.
[0032] A substrate camera 946 and a mounting head 943 are arranged side-by-side and facing downwards on the X-axis moving body 942. The substrate camera 946 captures images of the position marks attached to the substrate K from above, accurately determining the stopping position of the substrate K. A component camera 947 is arranged facing upwards between the substrate transport device 92 and the component supply device 93. The component camera 947 captures images of and identifies the components held by the nozzle 95 from below as the mounting head 943 moves from the component supply device 93 to the substrate K. This determines the correctness of the component type and detects the position and orientation of the components relative to the nozzle 95, reflecting this information in the mounting operation. Examples of the substrate camera 946 and component camera 947 include digital imaging devices with imaging elements such as CCD (Charge Coupled Device) and CMOS (Complementary Metal-Oxide Semiconductor).
[0033] The control unit, not shown in the diagram, is assembled on base 91, and its location is not particularly limited. The control unit is constructed using a computer device. Alternatively, the control unit can be configured with multiple CPUs distributed within the machine and interconnected. Based on installation operation data created according to the type of substrate product (substrate K), the control unit controls the substrate handling device 92, the component supply device 93, and the component transfer device 94 to perform component installation operations. The installation operation data includes component information related to the type and shape of substrate K and components, as well as corresponding information establishing a mapping between the type of component and the type of belt feeder (8A, 8B, 8C, 8D) used.
[0034] 2. Structural example of belt feeder 8A
[0035] Belt feeders (8A, 8B, 8C, 8D) are a type of component feeder that detachably loads and holds multiple components onto a reel RL (component holder). The four types of belt feeders (8A, 8B, 8C, 8D) have similar structures; therefore, the first type, belt feeder 8A, will be used as an example for explanation. Figure 2 The belt feeder 8A shown pulls a carrier belt CT containing multiple components from the reel RL and feeds it in a predetermined feed direction, supplying components at a predetermined supply position 816. Figure 1 The direction from left to right is the feed direction of the carrier CT, with the left side being the upstream side and the right side the downstream side. The belt feeder 8A has various components assembled in the feeder body 81, including the side plates, and is constructed to be relatively thin in the width direction. In addition to the feeder body 81, the belt feeder 8A also consists of a conveying mechanism 83, a belt stripping mechanism 84, a belt guide 85, a feeder control unit 86, and an indicator light 87.
[0036] The feeder body 81 includes a disassembly / removal track 811, a reel holding part 812, an opening / closing plate 813, a conveyor path 815, and a locking mechanism 818. The disassembly / removal track 811 is located on the bottom surface of the feeder body 81 and is inserted into a slot 932 during installation into the component mounting machine 9. From the upper side to the lower side of the downstream end face of the feeder body 81, an upper positioning pin 821, a connector 822, and a lower positioning pin 823 are sequentially provided. The upper positioning pin 821 and the lower positioning pin 823 engage with positioning holes provided on the tray table 931 to position the belt feeder 8A. When the belt feeder 8A is positioned, the connector 822 automatically engages with the receiving-side connector provided on the tray table 931. As a result, the belt feeder 8A is supplied with power, and the feeder control unit 86 is communicatively connected to the control device of the component mounting machine 9.
[0037] The reel holding section 812 is composed of multiple frame members forming a large circular internal space at approximately the center of the feeder body 81. The reel holding section 812 holds the reel RL within the internal space, allowing it to rotate. A hinged plate 813, covering more than half of the lower side of the internal space, is pivotally supported by a support 914 located near the mounting / unmounting track 811. The reel RL can be mounted or dismounted by opening the hinged plate 813 by pivoting downwards around the support 914.
[0038] The belt transport path 815 is essentially a passageway for feeding the carrier belt CT in a predetermined feed direction. The belt transport path 815 can be formed into a rectangular cylindrical shape, for example, using a base plate, two side plates, and a top plate; alternatively, part of the cylindrical shape may be omitted. The belt transport path 815 starts near the reel RL, extends diagonally upwards and downstream, then extends roughly horizontally downstream from the middle, ending at the upper part of the downstream end of the feeder body 81. A predetermined feed position 816 with an upward opening is defined near the end of the belt transport path 815.
[0039] A stripping mechanism 84 is provided upstream of the supply position 816 on the belt transport path 815. A belt guide 85 is disposed above the stripping mechanism 84. The belt guide 85 forms part of the belt transport path 815 and has a supply position 816. The belt guide 85 applies downward force (not shown) to press the carrier belt CT against the base plate of the belt transport path 815. As a result, the teeth of the sprocket 831 (described later) reliably engage with the feed hole of the carrier belt CT, and the relative height of the carrier belt CT with respect to the stripping mechanism 84 is stabilized.
[0040] The conveyor path 815 guides the carrier tape CT pulled from the tape reel RL to the tape stripping mechanism 84. The conveyor path 815 also guides the partially stripped carrier tape CT from the tape stripping mechanism 84 to the supply position 816. At the supply position 816, the carrier tape CT with the component removed is bent downwards and discharged downwards.
[0041] A locking mechanism 818 is located on the upper part of the upstream side of the feeder body 81. The locking mechanism 818 consists of a locking pin 81A, a locking operation component 81B, and a locking sensor 81C. The locking pin 81A is a cylindrical component held by the feeder body 81 to allow vertical movement. Normally, the locking pin 81A is pushed upwards by a force-applying spring (not shown in the attached diagram) to lock, restricting the disassembly of the belt feeder 8A. The locking operation component 81B is a Y-shaped component with a central pivot point. When driven by automatic or manual oscillation, the locking operation component 81B drives the locking pin 81A downwards to release the lock, allowing the disassembly of the belt feeder 8A. The locking sensor 81C detects the position of the locking pin 81A, i.e., whether it is locked, and outputs this information to the feeder control unit 86.
[0042] The feeding mechanism 83 feeds the carrier tape CT at regular intervals, sequentially supplying components at the supply position 816. The feeding mechanism 83 consists of a sprocket 831, a servo motor (not shown), and a gear mechanism. The sprocket 831 is positioned below the conveyor path 815 and approximately directly below the guide member 85, and is rotatably supported on the feeder body 81. The teeth of the sprocket 831 protrude from slots formed in the base plate of the conveyor path 815 and engage with the feed holes of the carrier tape CT. The sprocket 831 is driven to rotate by the servo motor via the gear mechanism, feeding the carrier tape CT in the feeding direction. Furthermore, the sprocket 831 is driven to rotate in the opposite direction when the servo motor reverses, causing the carrier tape CT to return in the opposite direction.
[0043] The feeder control unit 86 is located on the lower part of the upstream side of the feeder body 81, and its position is not limited. The feeder control unit 86 is communicatively connected to the control device of the component mounting machine 9 via connector 822. The feeder control unit 86 controls the feeding mechanism 83 to advance the component feeding operation according to the instructions from the control device. In addition, the feeder control unit 86 monitors the status of the locking mechanism 818. The feeder control unit 86 stores identification information for individual belt feeders 8A and sends identification information upon request from other control units.
[0044] Indicator lights 87 are located near the lower part of the upstream end face of the feeder body 81. Indicator lights 87 can combine illumination, flashing, and extinguishing to display three or more statuses. Furthermore, by variably switching the flashing interval or changing the illumination color, indicator lights 87 can display four or more statuses. Multiple indicator lights 87 can also be provided. The feeder control unit 86 controls the illumination of the indicator lights 87, displaying various statuses such as operating status, adjustment status, and error status.
[0045] 3. Structure of the feeder storage system 1 in the embodiment
[0046] Next, refer to Figures 3 to 5The structure of the feeder storage system 1 according to the embodiment will be described. The feeder storage system 1 not only stores the belt feeders (8A, 8B, 8C, 8D), but also automates or reduces labor intensity in the transfer within the system, handling with external systems, and the assembly / disassembly of the belt reels RL. For example... Figure 3 As shown, the feeder storage system 1 consists of six storage bins (21-26), a departure / arrival station 3, a tray loading / unloading device 4, a transfer device 5, and a control device 6. Figure 3 In the structural example shown, starting from the left, the departure / arrival station 3, six storage compartments (21-26), and the reel unloading device 4 are arranged side by side. The structure of the feeder storage system 1 can also be reversed from left to right, but the order of arrangement is not allowed to be changed. That is, the departure / arrival station 3 and the reel unloading device 4 are not allowed to be arranged in the center of the left-right direction.
[0047] The leftmost of the six storage compartments (21-26) is designated as the first storage compartment 21, and the remaining compartments to the right are designated as the second to fifth storage compartments 22 through 25, with the rightmost compartment designated as the sixth storage compartment 26. For example... Figure 4 As shown, the six storage compartments (21-26) are each shaped like boxes opening to the front, each having an upper storage shelf 27 and a lower storage shelf 28. The storage shelves (27, 28) each have multiple shelves arranged side-by-side in the left-right direction. Figure 4 The example shows 14 storage locations, number 29. In reality, there are more storage locations, number 29.
[0048] Multiple storage positions 29 each have slots for inserting the mounting and dismounting rails 811, capable of accommodating belt feeders (8A, 8B, 8C, 8D). The four types of belt feeders (8A, 8B, 8C, 8D) occupy a number of storage positions 29 corresponding to their width dimensions. Each storage position 29 has positioning holes for the upper positioning pin 821 and the lower positioning pin 823 to engage, and a receiving-side connector for the connector 822 to automatically engage. Therefore, the belt feeders (8A, 8B, 8C, 8D) stored in the storage positions 29 are powered, and the feeder control unit 86 is communicatively connected to the control device 6.
[0049] Each storage compartment (21-26) has a rack indicator light 2A located on the upper side of each storage rack (27, 28). The rack indicator light 2A uses an on / off state with changing display colors to distinguish the area and model classification storage partition set for each storage rack (27, 28) (details described later). In addition, the storage compartments (21-26) have a position indicator light 2B located on the upper side of each storage position 29. The position indicator light 2B uses an on / off state to distinguish the area and model classification storage partition set for each storage position 29. Alternatively, the indicator light 87 of the belt feeder (8A, 8B) stored in the storage position 29 can be used instead of the position indicator light 2B.
[0050] The size of the storage compartments (21-26) is not limited to the above description. That is, a single large storage compartment with multiple storage racks in both the vertical and horizontal directions can be used. Conversely, multiple small storage compartments with one storage rack each can be used. Furthermore, each storage compartment (21-26) does not need to facilitate the insertion and removal of the belt feeders (8A, 8B, 8C, 8D) based on the locking and unlocking operations of the locking mechanism 818, but it can also be configured to require locking and unlocking operations.
[0051] like Figure 3 As shown, departure / arrival station 3 is located to the left of the first storage compartment 21. The front surface of departure / arrival station 3 is aligned with the front surface of the storage compartments (21-26). Departure / arrival station 3 is the station where the automated guided vehicle 7 departs and arrives. Figure 5 As shown, the automated guided vehicle 7 loads and transports the feeder bin 71. The feeder bin 71 is used to efficiently transport the belt feeders (8A, 8B, 8C, 8D) between the departure / arrival station 3 and the component mounting machine 9. The feeder bin 71 is formed in a box shape with at least one of its front and rear surfaces omitted. The feeder bin 71 has multiple receiving positions arranged side by side along its width inside, accommodating multiple belt feeders (8A, 8B, 8C, 8D).
[0052] The feeder bin 71 is preferably shaped to be approximately half the width of the pallet table 931 in the X-axis direction. Therefore, by using two feeder bins 71, all belt feeders (8A, 8B) equipped on the pallet table 931 can be replaced as a whole. To optimize the overall replacement efficiency, two departure / arrival positions for the automated guided vehicle 7 and two placement positions for the feeder bins 71 are arranged side-by-side on either side of the departure / arrival station 3. Alternatively, the feeder bin 71 can be shaped to be approximately equal to the full width of the pallet table 931, allowing for overall replacement using only one feeder bin 71.
[0053] The operation of inserting the belt feeders (8A, 8B, 8C, 8D) into the feeder bin 71 located at the departure / arrival station 3 and the operation of pulling them out in the opposite direction are performed by the transfer device 5. The feeder bin 71 is automatically transferred between the departure / arrival station 3 and the automated guided vehicle 7. As a loading and unloading device for the transfer, a roller conveyor 73 is provided on the side of the automated guided vehicle 7. However, it is not limited to this, and the loading and unloading device may also be provided on the side of the departure / arrival station 3.
[0054] The automated guided vehicle 7 travels along the path shown by the path display belt 75, for example, transporting the feeder bin 71 to the three component mounting machines 9 that constitute the substrate assembly line 9A. Alternatively, the automated guided vehicle 7 can employ other travel methods, such as detecting surrounding conditions or predetermined markers to determine its current position and travel path. Furthermore, the automated guided vehicle 7 can also carry multiple individual belt feeders (8A, 8B, 8C, 8D) without using the feeder bin 71. The automated guided vehicle 7 is one type of transport device for transporting belt feeders (8A, 8B, 8C, 8D) towards the component mounting machines 9.
[0055] The area equipped with departure and arrival stations 3 becomes the handover area A2 for conveyor belt feeders (8A, 8B, 8C, 8D) that are transported towards the component mounting machine 9. Figure 6 As another method of handling, a belt conveyor can be used when the component mounting machine 9 is far from the transfer area A2, and an arm robot can be used when the component mounting machine 9 is close to the transfer area A2.
[0056] like Figure 3 As shown, the reel loading / unloading device 4 is positioned to the right of the sixth storage compartment 26. In other words, the reel loading / unloading device 4 is positioned on the opposite side of the departure / arrival station 3, across the storage compartments (21-26). The reel loading / unloading device 4 automatically performs loading and unloading operations (loading and unloading operations) of the reel RL relative to the belt feeders (8A, 8B, 8C, 8D). The reel loading / unloading device 4 has a box-shaped housing 41 that is larger than the storage compartments (21-26). The right front surface 411 of the front side of the housing 41 protrudes forward more than the left front surface 412. The reel loading / unloading device 4 is positioned such that the left front surface 412 of the housing 41 is aligned with the front surface of the storage compartments (21-26).
[0057] A reel loading inlet 413 is provided on the right front surface 411 of the housing 41, and a feeder insertion port 414 is provided on the left front surface 412. A reel loading outlet (not shown) is provided on the rear surface of the housing 41. The operator moves the reels RL loaded in the belt feeders (8A, 8B, 8C, 8D) into the reel removal device 4 through the reel loading inlet 413. The operator also removes the reels RL removed from the belt feeders (8A, 8B, 8C, 8D) from the reel loading outlet. Meanwhile, the conveyor 5 inserts the belt feeders (8A, 8B, 8C, 8D) that will be used for loading and unloading operations into the reel removal device 4 through the feeder insertion port 414. The conveyor 5 then removes the belt feeders (8A, 8B, 8C, 8D) that have undergone loading or unloading operations from the feeder insertion port 414.
[0058] The reel-mounted disassembly device 4 is a type of retainer disassembly device that performs the disassembly and assembly of the component retainer relative to the component feeder, and allows the operator to insert and remove the component retainer. Furthermore, the area where the reel-mounted disassembly device 4 is located is called the retainer disassembly area A32 (see reference). Figure 6 ), and becomes work area A3 (see reference) where operators perform pre-arranged operations related to belt feeders (8A, 8B, 8C, 8D). Figure 6 For reference, the applicant of this application has disclosed a detailed internal structure example of a reel-mounting device 4 in International Publication No. 2023 / 286209.
[0059] like Figure 3 As indicated by arrow T1, the transfer device 5 moves in the left-right direction in front of the left front surface 412 of the departure / arrival station 3, the storage warehouse (21~26), and the reel unloading device 4, transferring the belt feeders (8A, 8B, 8C, 8D). The transfer device 5 consists of a device body 51, a pair of left and right intrusion monitoring sensors 52, and a control unit 53. The device body 51 has a moving mechanism, a lifting unit, and a feeder operating unit (not shown in the figure).
[0060] The moving mechanism consists of, for example, traveling wheels and a drive source. The traveling wheels travel along a travel track (not shown) or on the ground. The drive source for rotating the traveling wheels can be, for example, a highly controllable servo motor or pulse motor. The lifting unit is installed inside the main body 51 in a way that allows it to be raised and lowered. The lifting drive mechanism for driving the lifting unit uses a ball screw feed mechanism or a linear motor mechanism. A feeder operating unit is installed in the lifting unit. The feeder operating unit holds the belt feeders (8A, 8B, 8C, 8D) internally and operates the belt feeders (8A, 8B, 8C, 8D) in the forward and backward direction. A battery or a contactless power supply mechanism is used as the power source for the electrical components within the main body 51.
[0061] In the rising position of the lifting unit, the feeder operating unit is positioned at the height of the upper storage rack 27 of the storage bins (21-26), allowing the belt feeders (8A, 8B, 8C, 8D) to be placed and removed relative to the storage rack 27. Furthermore, the feeder operating unit is positioned at the height of the feeder compartment 71 placed in the departure / arrival station 3 and the feeder insertion port 414 of the reel unloading device 4, allowing the belt feeders (8A, 8B, 8C, 8D) to be placed and removed relative to the feeder compartment 71 and the feeder insertion port 414. Conversely, in the descending position of the lifting unit, the feeder operating unit is positioned at the height of the lower storage rack 28 of the storage bins (21-26), allowing the belt feeders (8A, 8B, 8C, 8D) to be placed and removed relative to the storage rack 28.
[0062] A pair of intrusion monitoring sensors 52 are respectively installed on the left and right sides of the lower front part of the main body 51 of the device. The intrusion monitoring sensors 52 detect intruders that enter the movement range of the transfer device 5 and output a detection signal to the control unit 53. Intruders are specifically equivalent to operators, trolleys brought in by operators, or other equipment. The intrusion monitoring sensors 52 are, for example, non-contact sensors using infrared or ultrasonic waves. Alternatively, the intrusion monitoring sensors 52 can also be installed on the outside of the transfer device 5, such as on the front surface of the storage compartments (21-26).
[0063] The control unit 53 is constructed using a computer device, and its placement is not particularly limited. The control unit 53 has three main functional units constructed using software: a movement control unit 54, an operation control unit 55, and a movement restriction unit 56. The movement control unit 54, according to instructions from the control device 6, controls the movement mechanism and lifting unit to move the feeder operating unit to the instructed operating position. The operation control unit 55 controls the feeder operating unit, now in the operating position, to perform the insertion and removal operations of the belt feeders (8A, 8B, 8C, 8D).
[0064] The movement restriction unit 56 determines whether an intruder has been detected based on the detection signal from the intrusion monitoring sensor 52. If an intruder is detected, the movement restriction unit 56 stops the control of the movement control unit 54, restricting the movement of the transfer device 5. This prevents the transfer device 5 from colliding with the intruder. Furthermore, if the intruder is a worker, the safety of the worker is ensured. For reference, the applicant of this application disclosed a detailed structural example of the transfer device 5 in International Publication No. 2022 / 118380.
[0065] Figure 3The control device 6 shown is constructed using a computer device, and its placement is not particularly limited. The control device 6 is communicatively connected to the production line management device 9B, which manages the substrate assembly line 9A. The substrate assembly line 9A consists of three component mounting machines 9, along with a solder printer (excluding reference numerals), a printing inspection machine, a substrate appearance inspection machine, and a reflow machine arranged side-by-side. The production line management device 9B manages the operation of these seven substrate assembly machines based on a production plan 9C stored in a memory. The substrate assembly line 9A can be modified in its production line structure and can also consist of multiple production lines.
[0066] Production plan 9C stores information such as production quantity, production sequence, and production end date for multiple types of substrate products. Furthermore, production plan 9C associates the installation operation data of each of the three component mounting machines 9 with the various types of substrate products. Therefore, it can be considered that production plan 9C contains corresponding information establishing a relationship between the type of component and the model of the belt feeder (8A, 8B, 8C, 8D) used. Control device 6 can obtain production plan 9C and the corresponding information contained in production plan 9C from production line management device 9B, or can share it with production line management device 9B.
[0067] Control device 6 controls each component of the feeder storage system 1. Specifically, control device 6 communicates with the belt feeders (8A, 8B, 8C, 8D) stored in the storage bins (21-26) to obtain identification information. Thus, control device 6 manages the identification information of the belt feeders (8A, 8B, 8C, 8D) by establishing a correspondence between them and their storage locations 29. Furthermore, control device 6 controls the illumination of the rack indicator lights 2A and position indicator lights 2B in the storage bins (21-26). Moreover, control device 6 uses wired communication to control the disassembly and assembly operations of the reel unloading device 4, and uses wireless communication to control the transfer operations of the transfer device 5. Additionally, control device 6 collaborates with the transport control unit (not shown) that controls the automated guided vehicle (AGV) 7 to manage the transport operations, loading and unloading operations, etc., of the AAV 7.
[0068] The control device 6 comprises three main functional units using software: a setting unit 61, a recycling command unit 62, and a preparation command unit 63. The setting unit 61 sets and changes the areas and the machine type classification storage zones for the six storage compartments (21-26). The recycling command unit 62 controls the recycling of the belt feeders (8A, 8B, 8C, 8D) after use in the component mounting machine 9. The preparation command unit 63 controls the preparation of the belt feeders (8A, 8B, 8C, 8D) to be used next in the component mounting machine 9. Detailed functions of the three units will be described later.
[0069] 4. Setting of storage partitions based on area and model classification in setting unit 61
[0070] Next, refer to Figure 6 The detailed functions of the setting unit 61 will be explained. Figure 6 The diagram of the transfer device 5 is omitted. As described above, the area where the departure and arrival stations 3 are configured is the handover area A2, the area where the reel disassembly and assembly device 4 is configured is the holding part disassembly and assembly area A32, and the work area A3. The setting unit 61 sets a portion of the six storage compartments (21-26) near the handover area A2 as the storage area A1, and sets the remaining portion far from the handover area A2 as the work area A3 and the moving-in and moving-out area A31.
[0071] Storage area A1 is the area where prepared belt feeders (8A, 8B, 8C, 8D) with reels RL loaded and intended for use, as specified in production plan 9C, are stored. Work area A3 is the area where operators perform scheduled operations related to the belt feeders (8A, 8B, 8C, 8D). Work area A3 is located on the opposite side of transfer area A2, across from storage area A1. The loading / unloading area A31 is the area within work area A3 other than the holding / removal area A32. In loading / unloading area A31, operators perform loading operations on belt feeders (8A, 8B, 8C, 8D) that are intended for use but not loaded with reels RL. Additionally, in loading / unloading area A31, operators perform unloading operations on belt feeders (8A, 8B, 8C, 8D) that are not intended for use.
[0072] exist Figure 6 In the illustrated setup, storage areas A1 include a first storage bin 21, a second storage bin 22, a third storage bin 23, and a fourth storage bin 24, located near the transfer area A2. Additionally, storage bins 25 and 26, located further away from the transfer area A2, are designated as the work area A3 and the loading / unloading area A31. That is, the setup unit 61 assigns the six storage bins (21-26) to the storage area A1 and the loading / unloading area A31. Based on this setup, the transfer device 5 transfers belt feeders (8A, 8B, 8C, 8D) between the storage area A1, the transfer area A2, and the work area A3.
[0073] The setting unit 61 also sets the fifth storage compartment 25 and the sixth storage compartment 26, which are set as the loading and unloading area A31, as multiple model-classified storage areas divided according to the model of the belt feeder (8A, 8B, 8C, 8D). Figure 6In the illustrated configuration example, the upper storage rack 27 of the sixth storage compartment 26 is assigned to the model classification storage section of the belt feeder 8A of the first model, and the lower storage rack 28 is assigned to the model classification storage section of the belt feeder 8B of the second model. Furthermore, the upper storage rack 27 of the fifth storage compartment 25 is assigned to the model classification storage section of the belt feeder 8D of the fourth model, and the lower storage rack 28 is assigned to the model classification storage section of the belt feeder 8C of the third model.
[0074] In this allocation, the relatively larger quantities of the first and fourth models are assigned to the upper storage rack 27, while the relatively smaller quantities of the second and third models are assigned to the lower storage rack 28. This is advantageous in terms of improving transfer efficiency. The reason is that when transferring the belt feeders (8A, 8B, 8C, 8D) between the upper storage rack 27 and the departure / arrival station 3 and the reel unloading device 4, the lifting action of the lifting unit of the transfer device 5 is not required. In contrast, the lifting action of the lifting unit is required in the lower storage rack 28.
[0075] In addition, the setting unit 61 controls the illumination of the shelf display lights 2A to differentiate the display of the multiple model classification and storage areas. Figure 6 In the illustrated lighting control example, the upper shelf indicator 2A of the sixth storage compartment 26 is illuminated in red to indicate the first model. Additionally, the lower shelf indicator 2A of the sixth storage compartment 26 is illuminated in white to indicate the second model. Furthermore, the upper shelf indicator 2A of the fifth storage compartment 25 is illuminated in blue to indicate the fourth model, and the lower shelf indicator 2A is illuminated in green to indicate the third model. Meanwhile, within storage area A1, all shelf indicator lights 2A in storage compartments 21 through 24 are turned off.
[0076] As described above, the rack indicator light 2A serves as a display unit that differentiates between the storage area A1 and the transfer / removal area A31 based on whether it is off or on. Operators can confirm the transfer / removal area A31 by observing the illumination of the rack indicator light 2A, enabling them to perform transfer / removal operations for the belt feeders (8A, 8B, 8C, 8D). This reduces the possibility of operators mistakenly entering the storage area A1 and interfering with the transfer device 5. Furthermore, the rack indicator light 2A also serves as a display unit that differentiates between the first to fourth machine types based on their illuminated color. Operators can identify the type of belt feeder (8A, 8B, 8C, 8D) by observing the illuminated color of the rack indicator light 2A, thus improving the efficiency of transfer / removal operations.
[0077] Here, it is possible that all storage positions 29 of the storage racks (27, 28), which are already set as a model-specific storage area, are filled with belt feeders (8A, 8B, 8C, 8D). In this case, the setting unit 61 changes the setting of the storage racks (27, 28), which are already set as storage area A1 and are currently idle, to a model-specific storage area.
[0078] For a specific example, it is possible that all storage positions 29 of the upper storage rack 27 of the sixth storage compartment 26 are filled with the belt feeder 8A of the first model. In this case, the setting unit 61 changes the setting of the upper storage rack 27 of the fourth storage compartment 24, which is currently set as storage area A1 and is in an idle state, to a model-specific storage area for the first model. Furthermore, the setting unit 61 causes the indicator light 2A of the upper shelf of the fourth storage compartment 24 to light up in red to indicate the first model. Through this change of setting, the scope of storage area A1 and the loading / unloading area A31 is changed. Moreover, the boundary DL between storage area A1 and loading / unloading area A31 becomes Figure 6 The broken line is shown by the dashed line. Furthermore, when all storage positions 29 of the upper storage rack 27 of the fifth storage compartment 25 are filled by the belt feeder 8D of the fourth model, the setting unit 61 changes the setting of the lower storage rack 28 of the fourth storage compartment 24 to the model classification storage area of the fourth model, and causes the lower shelf indicator light 2A to light up in blue to indicate the fourth model.
[0079] In the above-described setting example, the setting unit 61 sets and changes the area and model-specific storage partitions on a unit basis, using storage racks (27, 28). As another setting method 1, the setting unit 61 can also set the storage units (21-26) as units. For example, when the older belt feeder 8D of the fourth model is not used normally as a spare, the setting unit 61 can set the first storage unit 21 to the third storage unit 23 as storage area A1, and the fourth storage unit 24 to the sixth storage unit 26 as loading / unloading area A31. Furthermore, the setting unit 61 can assign the sixth storage unit 26 to the model-specific storage partition of the first model, the fifth storage unit 25 to the model-specific storage partition of the second model, and the fourth storage unit 24 to the model-specific storage partition of the third model.
[0080] Furthermore, as another method 2 for setting, the setting unit 61 can also set multiple storage positions 29 at a time. In this case, the setting unit 61 controls the illumination of the position indicator light 2B or the indicator light 87 of the belt feeders (8A, 8B, 8C, 8D) instead of the rack indicator light 2A. For example, the setting unit 61 can target the lower storage rack 28 of the sixth storage compartment 26, assigning the 8 storage positions 29 on the right to the second type of machine type classification storage area, and assigning the 6 storage positions 29 on the left to the third type of machine type classification storage area. Thus, the lower storage rack 28 of the sixth storage compartment 26 can store four second type of machine type belt feeders 8B and two third type of machine type belt feeders 8C. Alternatively, the setting unit 61 can omit the setting of the machine type classification storage area. In this case, the belt feeders (8A, 8B, 8C, 8D) are stored in the loading / unloading area A31 without distinguishing between machine types.
[0081] 5. Detailed functions of the recycling instruction unit 62 and actions related to recycling processing.
[0082] Next, refer to Figure 7 and Figure 8 The detailed functions of the recycling instruction unit 62 and the operation of the feeder storage system 1 related to recycling processing are explained. After use, the tape feeders (8A, 8B, 8C, 8D) in the component mounting machine 9 are retrieved from the component mounting machine 9 by the automated guided vehicle 7 and transported to the transfer area A2. The subsequent recycling processing is mainly performed by the recycling instruction unit 62. Recycling processing is performed when the tape feeders (8A, 8B, 8C, 8D) that have consumed all components on the reel RL are recycled. Additionally, recycling processing is performed when the tape feeders (8A, 8B, 8C, 8D) that are no longer used due to changes in the type of substrate products produced are recycled.
[0083] Based on production plan 9C, the recycling instruction unit 62 determines the system's transfer destination for the belt feeders (8A, 8B, 8C, 8D) to be moved to transfer area A2. Specifically, the recycling instruction unit 62 determines storage area A1 as the transfer destination for the belt feeders (8A, 8B, 8C, 8D) scheduled for use in production plan 9C. Furthermore, the recycling instruction unit 62 determines the idle storage location 29 within storage area A1, near transfer area A2, as the transfer destination for the belt feeders (8A, 8B, 8C, 8D) scheduled for use.
[0084] Specifically, for transfer destinations using predetermined belt feeders (8A, 8B, 8C, 8D), the first storage bin 21 closest to the handover area A2 is given priority, as is the upper storage rack 27 with high transfer efficiency. Figure 6 and Figure 8In the first storage compartment 21, the upper shelf 27 is full, and the storage position 29 of the lower shelf 28 is determined as the transfer destination. At this time, the second to fourth storage compartments 24 are idle. Later, when the lower shelf 28 of the first storage compartment 21 is full, the storage position 29 of the upper shelf 27 of the second storage compartment 22 is determined as the transfer destination. Therefore, when the belt feeders (8A, 8B, 8C, 8D) are used again, the transfer distance from storage area A1 to transfer area A2 is shortened, thus further improving the transfer efficiency of the transfer device 5. Furthermore, unlike the inbound / outbound area A31, in storage area A1, it is not necessary to separate the belt feeders (8A, 8B, 8C, 8D) by model.
[0085] Furthermore, the recycling instruction unit 62 designates work area A3 as the transfer destination for items not included in the production plan 9C and not using the predetermined belt feeders (8A, 8B, 8C, 8D). Work area A3 includes both the inbound / outbound area A31 and the component assembly / disassembly area A32. Strictly speaking, the recycling instruction unit 62 also considers whether there is any component remaining on the reels RL filled in the belt feeders (8A, 8B, 8C, 8D) when determining the transfer destination. The recycling instruction unit 62 instructs the transfer device 5 to the determined transfer destination and performs the transfer.
[0086] The integrated operation of the feeder storage system 1 related to recycling is as follows: Figure 7 As shown. In Figure 7 In step S1, the automated guided vehicle 7 transports the feeder bin 71 loaded by the component mounting machine 9 to the transfer area A2 (departure / arrival station 3). This transport action... Figure 8 The arrow M1 indicates this. The feeder bin 71, which is being transported, houses multiple belt feeders (8A, 8B, 8C, 8D) that have finished their use in the component mounting machine 9. The configuration of the multiple belt feeders (8A, 8B, 8C, 8D) can be changed during each recycling process. In parallel with the transport operation described above, the identification information of the multiple belt feeders (8A, 8B, 8C, 8D) and the presence or absence of components are sent from the production line management device 9B to the control device 6.
[0087] In the next step S2, the recycling instruction unit 62 selects a belt feeder, such as belt feeder 8A of the first model, within the feeder bin 71 as the processing target. In the next step S3, the recycling instruction unit 62 branches the operation flow based on whether there are any components in the belt feeder 8A of the processing target. If there are any components remaining, the operation flow branches to step S11. In step S4, if there are no components remaining, the recycling instruction unit 62 determines the transfer destination as the retainer removal area A32 (reel removal device 4) and instructs the transfer device 5. The transfer device 5 transfers the belt feeder 8A from the feeder bin 71 to the reel removal device 4 and inserts it into the feeder insertion port 414. This transfer operation... Figure 8 The arrow M4 indicates this. In the next step S5, the reel removal device 4 removes the empty reel RL from the belt feeder 8A.
[0088] In the next step S6, the recycling instruction unit 62 determines the transfer destination of the belt feeder 8A as the transfer-in / transfer-out area A31. Even if there is a usage plan in the belt feeder 8A, since the reel RL is not loaded, the transfer destination is not the storage area A1 but the transfer-in / transfer-out area A31. Furthermore, the recycling instruction unit 62 determines the type-specific storage area for the transferred belt feeder 8A based on its type. Specifically, the recycling instruction unit 62 determines the type-specific storage area for the transferred belt feeder 8A as the upper storage rack 27 of the sixth storage compartment 26, based on the belt feeder 8A being the first type.
[0089] In the next step S7, the setting unit 61 checks whether the determined model category storage area is full. Specifically, it checks whether the upper storage shelf 27 of the sixth storage compartment 26 is full. If it is full, in step S8, the setting unit 61 changes the setting of the model category storage area. Specifically, it changes the setting of the upper storage shelf 27 of the fourth storage compartment 24 to the new model category storage area. If it is not full, step S8 is omitted, and the operation flow proceeds to step S9.
[0090] In step S9, following step S7 or S8, the recycling instruction unit 62 determines the model classification storage area set or changed by the setting unit 61 as the transfer destination and instructs the transfer device 5. The transfer device 5 removes the belt feeder 8A from the feeder insertion port 414 of the reel removal and installation device 4 and transfers it to the indicated model classification storage area. The transfer operation occurs when the upper storage rack 27 of the sixth storage compartment 26 is not full. Figure 8 The arrow M9 indicates this. After step S9 is executed, the action flow proceeds to step S10.
[0091] Additionally, in step S11, which branches off from step S3, the recovery instruction unit 62 determines whether there is a planned use of the belt feeder 8A in the production plan 9C. If there is no planned use, the recovery instruction unit 62 initiates the operation flow to step S6. That is, the recovery instruction unit 62 moves the belt feeder 8A, which contains residual components and is not planned for use, to the loading / unloading area A31 in its original form, and the scheduled operator performs the unloading operation. Alternatively, the recovery instruction unit 62 may also initiate the operation flow to step S4 (see step S4) if there is no planned use. Figure 7 (The dashed arrow). That is, the recycling instruction unit 62 will use the belt feeder 8A to transfer the belt reel RL to the belt reel disassembly device 4 to remove the remaining components, and the belt feeder 8A and belt reel RL will be removed by the operator.
[0092] Furthermore, in step S11 where the production plan 9C includes a predetermined use of the belt feeder 8A, the recycling instruction unit 62 determines the destination of the belt feeder 8A as an idle storage position 29 within the storage area A1, near the handover area A2, and instructs the transfer device 5 accordingly. The transfer device 5 then transfers the belt feeder 8A to the storage position 29 indicated from the feeder magazine 71. This transfer operation... Figure 8 This is indicated by arrow M12. Afterwards, the action flow merges with step S10.
[0093] In step S10, the recovery instruction unit 62 investigates whether the feeder bin 71 is empty or contains residual belt feeders (8A, 8B, 8C, 8D). If belt feeders (8A, 8B, 8C, 8D) remain in the feeder bin 71, the recovery instruction unit 62 returns the operation flow to step S2, selects the next belt feeder (8A, 8B, 8C, 8D), and repeats the operation flow after step S3. If the feeder bin 71 is empty, the operation flow proceeds to step S13. In step S13, the operator removes belt feeders (8A, 8B, 8C, 8D) that are not intended for use from the loading / unloading area A31, for example, returning them to a long-term storage equipment warehouse. This removal operation... Figure 8 The arrow M13 is used to indicate this.
[0094] Thus, the recycling process is completed. At the end of the recycling process, the prepared belt feeders (8A, 8B, 8C, 8D) that were scheduled for use in production plan 9C and loaded with reels RL are stored in storage area A1. Additionally, belt feeders (8A, 8B, 8C, 8D) that were scheduled for use but not loaded with reels RL are stored in the transfer in / out area A31.
[0095] 6. Detailed functions of the preparation instruction unit 63 and actions related to preparation processing.
[0096] Next, refer to Figure 9 and Figure 10 The detailed functions of the preparation instruction unit 63 and the operation of the feeder storage system 1 related to the preparation process will be explained. Next, the tape feeders (8A, 8B, 8C, 8D) used in the component mounting machine 9 are transported from the transfer area A2 to the component mounting machine 9 by the automated transport vehicle 7. The operations related to the previous preparation process are mainly performed by the preparation instruction unit 63. Preparation processing is performed when preparing tape feeders (8A, 8B, 8C, 8D) that replace the tape feeders (8A, 8B, 8C, 8D) that deplete all components on the tape reel RL. Additionally, preparation processing is performed when preparing newly used tape feeders (8A, 8B, 8C, 8D) due to changes in the type of substrate products being produced.
[0097] Based on production plan 9C, preparation instruction unit 63 selects belt feeders (8A, 8B, 8C, 8D) to be transported from storage area A1 to component mounting machine 9 by automated guided vehicle 7, and instructs transfer device 5 to transfer them to handover area A2. Upon receiving the instruction, transfer device 5 transfers the belt feeders (8A, 8B, 8C, 8D). As a result, the prepared belt feeders (8A, 8B, 8C, 8D) are automatically stored in feeder bin 71 in handover area A2.
[0098] In most cases, the prepared belt feeders (8A, 8B, 8C, 8D) stored in storage area A1 are insufficient, necessitating the preparation of loading reels RL into other belt feeders (8A, 8B, 8C, 8D). Therefore, when a predetermined reel RL is moved into the reel loading / unloading device 4 according to production plan 9C, preparation instruction unit 63 selects a suitable belt feeder (8A, 8B, 8C, 8D) from loading / unloading area A31 and instructs transfer device 5 to transfer it to reel loading / unloading device 4. Upon receiving the instruction, transfer device 5 transfers the belt feeders (8A, 8B, 8C, 8D). Thus, in reel loading / unloading device 4, reels RL are automatically loaded into belt feeders (8A, 8B, 8C, 8D).
[0099] Furthermore, the preparation instruction unit 63 instructs the transfer device 5 to transfer the belt feeders (8A, 8B, 8C, 8D) loaded with reels RL via the reel unloading device 4 to the storage area A1 or the transfer area A2. Upon receiving the instruction, the transfer device 5 performs the transfer of the belt feeders (8A, 8B, 8C, 8D). Specifically, the preparation instruction unit 63 directly transfers the most recently used belt feeders (8A, 8B, 8C, 8D) from the reel unloading device 4 to the feeder compartment 71 in the transfer area A2, realizing the transfer to the component mounting machine 9 as soon as possible. In addition, the preparation instruction unit 63 prepares the belt feeders (8A, 8B, 8C, 8D) to be used in the future and stores them in the storage area A1 until the start of use.
[0100] exist Figure 9 The diagram illustrates the integrated operation of the feeder storage system 1 related to the preparation process. At the start of the preparation process, an empty feeder bin 71 is placed at the departure / arrival station 3. Figure 9 In step S21, the production line management device 9B sends a production plan 9C indicating the need for preparation processing due to the progress of substrate operations or changes in the type of substrate product. The preparation instruction unit 63 obtains the production plan 9C. In the next step S22, the preparation instruction unit 63 selects one of the multiple corresponding information contained in the production plan 9C. As described above, the corresponding information is information that corresponds the type of component to the model of the belt feeder (8A, 8B, 8C, 8D) used. In the next step S23, the preparation instruction unit 63 checks whether the belt feeders (8A, 8B, 8C, 8D) that meet the corresponding information are in storage area A1. If they are, the operation flow branches to step S31.
[0101] In step S24, where the condition is not met, the preparation instruction unit 63 requests the operator to move in the belt feeders (8A, 8B, 8C, 8D) and reels RL that meet the corresponding information. In the next step S25, the operator who accepted the request moves the belt feeders (8A, 8B, 8C, 8D) that meet the corresponding information but are not loaded with reels RL into the loading / unloading area A31. This loading / unloading operation is performed in... Figure 10 The arrow M25 indicates this. In the next step S26, the operator moves the reel RL, which meets the corresponding information, into the reel loading / unloading device 4. This loading / unloading operation is... Figure 10 Arrow M26 is used to indicate this. In the next step S27, the transfer device 5 transfers the belt feeders (8A, 8B, 8C, 8D) that have been moved into and out of the transfer area A31 to the reel unloading device 4. This transfer action is performed in... Figure 10 The arrow M27 is used to indicate this.
[0102] Additionally, sometimes belt feeders (8A, 8B, 8C, 8D) that meet the corresponding information but are not loaded with reels RL remain in the loading / unloading area A31. In this case, in step S24, the preparation instruction unit 63 requests the operator to load only the reels RL that meet the corresponding information; otherwise, step S25 is omitted.
[0103] In step S28, the reel loading / unloading device 4 loads the belt feeders (8A, 8B, 8C, 8D) transferred by the transfer device 5 with the reels RL brought in by the operator. After step S29, we envision a scenario where the belt feeders (8A, 8B, 8C, 8D) are used at the nearest location. In step S29, the preparation command unit 63 instructs the transfer device 5 to transfer the belt feeders (8A, 8B, 8C, 8D) loaded with reels RL by the reel loading / unloading device 4 to the handover area A2. Upon receiving the command, the transfer device 5 performs the transfer of the belt feeders (8A, 8B, 8C, 8D). This transfer operation... Figure 10 This is indicated by arrow M29. After step S29 is executed, the action flow proceeds to step S30.
[0104] Additionally, in step S31, which branches off from step S23, the preparation instruction unit 63 instructs the transfer device 5 to transfer the belt feeders (8A, 8B, 8C, 8D) loaded with reels RL from storage area A1 to transfer area A2. Upon receiving the instruction, the transfer device 5 performs the transfer of the belt feeders (8A, 8B, 8C, 8D). This transfer operation... Figure 10 This is indicated by arrow M31. Afterwards, the action flow merges with step S30.
[0105] In step S30, the transfer device 5 inserts the belt feeders (8A, 8B, 8C, 8D) into the feeder bin 71. In the next step S32, the preparation instruction unit 63 determines whether the corresponding information is the last one. If it is not the last one, the preparation instruction unit 63 returns the operation flow to step S22, selects the next corresponding information, and repeats the operation flow after step S23. If the corresponding information is the last one, the preparation processing operation flow ends. Afterwards, the feeder bin 71 containing the belt feeders (8A, 8B, 8C, 8D) is transported by the automated guided vehicle 7 from the transfer area A2 to the component mounting machine 9.
[0106] In the feeder storage system 1 of this embodiment, the handover area A2, where the automated guided vehicle 7 (AGV7) handles the transfer of belt feeders (8A, 8B, 8C, 8D), and the work area A3, where operators perform predetermined tasks, are separated from the storage area A1. This separates the movement paths of the AAV7 and the operator, preventing overlap in their work. Furthermore, the chance of overlap between the work performed by the transfer device 5 and the operator is reduced. For example, even if the transfer device 5 performs a transfer operation between the storage area A1 and the handover area A2 in parallel with the operator performing predetermined tasks in work area A3, no obstruction occurs due to the separated movement paths. Therefore, the chance of work waiting due to overlap in work (or actions) between the AAV7, the transfer device 5, and the operator is reduced, and the reduction in work efficiency is suppressed.
[0107] 7. Application and Variations of the Implementation Methods
[0108] Furthermore, in the feeder storage system 1 of the embodiment, the setting unit 61 can also set the storage area A1 to be divided according to multiple uses. For example, the setting unit 61 can assign one component mounting machine 9 to each of the first storage compartment 21 to the third storage compartment 23 of the storage area A1, or assign different types of substrate products to the multiple storage racks (27, 28). Alternatively, the setting unit 61 can be omitted, and the storage area A1, the loading and unloading area A31, and the machine type classification storage partitions can be fixed.
[0109] Furthermore, the reel disassembly / removal device 4 can be replaced with a feeder support device. The feeder support device supports the belt feeders (8A, 8B, 8C, 8D) inserted by the transfer device 5 and opens the opening / closing plate 813, assisting the operator in disassembling and removing the reel RL. Alternatively, a rod feeder can be used instead of the belt feeders (8A, 8B, 8C, 8D), and the reel disassembly / removal device 4 can be replaced with a rod disassembly / removal device. The rod feeder is detachably mounted on a cylindrical rod that holds multiple components internally and is fitted into the slot 932 of the tray table 931. The rod disassembly / removal device automatically performs the disassembly / removal operation of the rod relative to the rod feeder, and the operator inserts and removes the rod. Various other applications and modifications are possible with this embodiment.
