Description

This specification relates to a feeder management method and a feeder management device when a substrate is produced based on a production plan that defines a production order of a plurality of types of substrates.

Facilities for producing boards on which a large number of electronic components are mounted include solder printing machines, electronic component mounting machines, reflow machines, and board inspection machines. It is common to connect these board production facilities to form a board production line. Of these, the electronic component mounting machine includes a board transfer device, a component supply device, a component transfer device, and a control device. As a typical example of a component supply device, there is known a configuration in which a plurality of feeders of a method of feeding out carrier tapes holding a plurality of electronic components are detachably arranged in a row.

In response to the diversification of consumer needs in recent years, the tendency of high-mix low-volume production has progressed, and there are cases where substrates are produced based on a production plan that defines the production order of multiple types of substrates. In this case, when the type of the substrate is changed, the setup change work for changing the component type of the electronic component supplied from the component supply device is performed. As a method of changing the component type, there are a first method of exchanging the reel around which the carrier tape is wound and a second method of exchanging the feeder itself. In the second method, the reel to be used next is held in the replacement feeder in advance, and the replacement feeder is equipped in the setup change operation. In general, the correspondence between the reel and the feeder is often managed by the correspondence of the ID code attached to each. Technical examples of this type of feeder management method are disclosed in Patent Documents 1 and 2.

The chip component supply device of Patent Document 1 has a reel holding portion that interchangeably holds a reel wound with a carrier tape, a rod-shaped member that holds the reel holding portion at one end, and a carrier arranged at the other end of the rod-shaped member. It is provided with a reel feeding means for feeding the tape, a reel guide portion for taking in the carrier tape and separating it into a component storage tape and a top tape, and a take-up reel for winding the top tape. According to the description of the embodiment, when the tape is replaced, the reel is rotated in the reverse direction to rewind the used tape and the top tape, and the reel guide portion is moved to the outside of the electronic component mounting machine to perform the replacement work. According to this, even in a situation where the reels are frequently replaced by using them, the replacement work can be made more efficient, and the work can be speeded up and the cost can be reduced.

Further, the feeder management method of Patent Document 2 includes a step of determining whether or not the current component type of the component used for the substrate type currently being produced is used for the next and subsequent substrate types, and a feeder based on the determination result. The feeder management device performs two steps during the execution of the current production job, which comprises a step to guide the handling work of. In addition, the guide step keeps the feeder in the current mounting slot when the current component type is used for the next board type, and the feeder is empty slot or current when the current component type is used for the next and subsequent board types. Store on the mounting machine shelf, store the feeder on the separate mounting machine shelf when the current component type is used for another electronic component mounting machine, and store the feeder on the warehouse shelf when the current component type is no longer used. Guidance will be displayed to the effect that it will be stored. According to this, it is possible to reduce the confirmation man-hours of the worker who confirms the contents of the setup change work, and it is possible to start the work quickly.

By the way, the feeder management method of Patent Document 2 is a technique of determining whether or not the feeder needs to be removed at the time of setup change work, and in addition, guiding the storage location of the removed feeder. Here, as the tendency of high-mix low-volume production develops, the number of types of electronic components increases, which greatly exceeds the number of feeders on hand, and setup change work frequently occurs. As a result, the frequency of the reel replacement work exemplified in Patent Document 1 increases.

However, the technique of Patent Document 2 does not describe the reel replacement work, and the operator is confused as to whether or not it is better to remove the reel from the feeder. In the past, in order to make this judgment accurately, it was necessary to investigate the production plan and confirm whether or not the electronic parts were planned to be used. Furthermore, as the frequency of reel replacement work increases, it takes a lot of time and effort.

Therefore, it is solved that the present specification provides a feeder management method and a feeder management device that can reduce the trouble of rewinding the carrier tape, eliminate the clutter on the reel to be removed, and improve the work efficiency as a result. It is an issue to be done.

The present specification is a method of managing a feeder that holds an electronic component and unwinds a carrier tape wound around the reel from the reel to supply the electronic component to a component supply position of an electronic component mounting machine. When the production of a substrate of a certain substrate type is completed and the production shifts to the production of the next substrate type, it is not used for the production of the next and subsequent substrate types among the component types of the electronic components supplied by the feeder respectively. The feeder comprises a recognition step for recognizing the component type and a rewinding step for rewinding the carrier tape holding the electronic component of the component type that is not used for the subsequent substrate type to the reel. , The tape feeding mechanism has a tape feeding mechanism for feeding and rewinding the carrier tape, and in the rewinding step, the tape feeding mechanism automatically rewinds the carrier tape based on the recognition result in the recognition step, feeder management. Disclose the method.

Further, the present specification is a feeder management device that holds an electronic component and unwinds a carrier tape wound around a reel from the reel to supply the electronic component to a component supply position of an electronic component mounting machine. When the production of a substrate of a certain substrate type is completed and the production shifts to the production of the next substrate type, among the component types of the electronic components supplied by the feeder, the production of the next and subsequent substrate types The recognition unit that recognizes the unused component type and the carrier tape that holds the electronic component of the component type that is not used for the next and subsequent board types are automatically rewound based on the recognition result by the recognition unit. Disclose a feeder management device comprising a return section.

In the feeder management method disclosed in the present specification, the reel to be removed is clarified by the recognition step, and the labor of rewinding the carrier tape is reduced by the rewinding step, so that the work efficiency of the work of removing the reel can be improved as a result. can.

(1. Configuration of electronic component mounting machine 1)
First, the feeder management method of the embodiment and the configuration of the electronic component mounting machine 1 to which the feeder management device is applied will be described. FIG. 1 is a plan view of an electronic component mounting machine 1 to which the feeder management method and the feeder management device of the embodiment are applied. The left-right direction of the paper surface in FIG. 1 is the X direction for transporting the substrate K, and the vertical direction of the paper surface is the Y direction. As shown in the figure, the electronic component mounting machine 1 is composed of a substrate transfer device 2, a component supply device 3, a component transfer device 4, and the like.

The substrate transfer device 2 is arranged on the upper surface of the machine base 9, conveys the substrate K in the X direction, and positions the substrate K at the mounting implementation position. The substrate transfer device 2 includes a pair of guide rails 21, a pair of conveyor belts 22, a clamp device 23, and the like. The pair of guide rails 21 extend in the X direction and are arranged parallel to each other. The pair of conveyor belts 22 is an annular shape on which the substrate K can be placed, and is provided so as to be rotatable inside the guide rails 21 facing each other. The clamp device 23 is arranged below the mounting implementation position set around the center in the X direction between the pair of guide rails 21. The substrate K is carried in and out by the conveyor belt 22 while being guided by the guide rail 21, and is positioned and fixed at the mounting implementation position by the clamp device 23.

The component supply device 3 is configured with a substantially rectangular pallet member 31 as a main member. On the upper surface of the pallet member 31, a plurality of slots 32 extending in the Y direction and arranged in the X direction are formed. The slot position where the slot 32 is formed corresponds to the arrangement position where the feeder 6 is equipped. A display unit 33 corresponding to each slot 32 is provided on the front upper portion of the pallet member 31. An LED lamp can be exemplified as the display unit 33, and the display unit 33 is not limited thereto. The component supply device 3 is provided with a plurality of feeders 6 detachably attached to the plurality of slots 32, respectively. The component supply device 3 has a component supply control unit 35 (shown in FIG. 3) that controls a display unit 33 and an equipped feeder 6.

The feeder 6 holds the reel R interchangeably on the rear side and has a component supply position 67 on the upper front side (details will be described later). In the example of FIG. 1, the pallet member 31 is provided with 16 sets of slots 32 and a display unit 33. A feeder 6 is provided in each of the slots 32 at 6 locations in total, 2 locations near the right end and 4 locations near the left end of the pallet member 31.

The component transfer device 4 includes a pair of fixed rails 41, a head moving rail 42, a mounting head 43, a suction nozzle 44, and the like. The pair of fixed rails 41 extend above the substrate transfer device 2 in the Y direction and are arranged in parallel with each other. The head moving rail 42 extends in the X direction, and both ends thereof are movably supported by the fixed rail 41. The head moving rail 42 is driven in the Y direction by the ball screw feeding mechanism (not shown). The mounting head 43 is movably supported by the head moving rail 42. The mounting head 43 is driven in the X direction by the ball screw feeding mechanism (not shown). The mounting head 43 has a suction nozzle 44 and a substrate recognition camera 45 facing downward. The suction nozzle 44 sucks and collects electronic components from the feeder 6 and mounts them on the positioned substrate K. The board recognition camera 45 recognizes the accurate coordinate position of the positioned board K.

A component recognition camera 5 is arranged between the board transfer device 2 and the component supply device 3. The component recognition camera 5 recognizes the suction state of the electronic component collected by the suction nozzle 44 from below.

FIG. 2 is a side view schematically illustrating a configuration example of the feeder 6. The feeder 6 is configured by attaching a reel holding shaft 61, a tape guide member 62, a sprocket 63, a drive motor 64, a feeder control unit 65, an operation panel 66, a tape detection sensor 68, and the like to a side plate 69. The reel holding shaft 61 is provided below the rear side of the side plate 69. The reel holding shaft 61 replaceably holds the reel R around which the carrier tape T for holding the electronic component is wound. In the present embodiment, the reel R of the reel holding shaft 61 can be replaced with the feeder 6 mounted in the slot 32. The structure is not limited to this, and the feeder 6 may be removed from the slot 32 to replace the reel R of the reel holding shaft 61.

The reel ID code Rid attached to each individual reel R is read by the code reading unit 36 (shown in FIGS. 1 and 3) of the component supply device 3 and recognized by the component supply control unit 35. A barcode can be exemplified as the reel ID code Rid, and a barcode reader can be exemplified as the code reading unit 36. The reel ID code Rid identifies the component type of the electronic component supplied from the carrier tape T wound around the reel R.

The tape guide member 62 extends forward and upward from the front side of the held reel R, and extends horizontally forward after reaching the upper edge of 69 of the side plate. The tape guide member 62 guides the carrier tape T unwound from the reel R to the component supply position 67 on the front upper side. A sprocket 63 is bearing under the front side of the tape guide member 62. The teeth on the outer periphery of the sprocket 63 are engaged in the sprocket holes of the carrier tape T. The drive motor 64 can rotationally drive the sprocket 63 in both the forward rotation direction and the reverse rotation direction. The drive motor 64 is controlled by the feeder control unit 65.

The feeder control unit 65 is a computer control device having a CPU and operating by software. The feeder control unit 65 stores a feeder ID code set for each individual feeder 6. The feeder control unit 65 is communicatively connected to the component supply control unit 35 via a connector 651 provided on the front surface. The sprocket 63, the drive motor 64, and the feeder control unit 65 constitute a tape feeding mechanism.

The operation panel 66 is provided on the upper surface near the rear of the side plate 69. The operation panel 66 has a pay-out switch 661 and a rewind switch 662. The pay-out switch 661 and the rewind switch 662 are manual switches operated by an operator, and the operation status thereof is transmitted to the feeder control unit 65. When the feeding switch 661 or the rewinding switch 662 is pressed, the sprocket 63 of the tape feeding mechanism is intermittently driven in the forward rotation or the reverse rotation. As a result, the carrier tape T is unwound little by little or rewound little by little.

The function of the operation panel 66 is restricted during normal operation, and the tape feeding mechanism feeds the carrier tape T by pitch feed and sequentially supplies electronic components to the component supply position 47. On the other hand, the function of the operation panel 66 is used in the setup change work when changing the type of the substrate K produced by the electronic component mounting machine 1. That is, the operator sets the reel R on the reel holding shaft 61, inserts the tip of the carrier tape T up to the sprocket 63, and then pushes the feeding switch 661. As a result, the tape feeding mechanism feeds the carrier tape T little by little.

On the other hand, regarding the removal of the reel R, two types of operation modes can be selected. The first operation mode is the automatic rewind mode, and the function of the operation panel 66 is not used. In the automatic rewinding mode, the tape feeding mechanism automatically rewinds the carrier tape T to the reel R. The second operation mode is a manual rewind mode, in which the function of the operation panel 66 is used. In the manual rewind mode, when the rewind switch 662 is pressed and held, the tape feeding mechanism allows the carrier tape T to be continuously rewound to the reel R. This facilitates the removal work of the reel R.

The automatic rewind mode is selected in the automatic rewind step described later, and the manual rewind mode is selected in the manual rewind step described later. Depending on the model of the feeder 6, only one of the automatic rewind mode and the manual rewind mode may be fixedly provided.

The tape detection sensor 68 is arranged at an inclined portion toward the rear side of the tape guide member 62. The tape detection sensor 68 detects the presence or absence of the carrier tape T to be unwound, and sends the detection result to the feeder control unit 65. Even if the carrier tape T is rewound by the tape feeding mechanism during the reel R replacement work, the tip of the carrier tape T returns only to the sprocket 63. After that, when the operator rewinds the tip of the carrier tape T to the reel R, the detection result of the tape detection sensor 68 changes from "with tape" to "without tape". Based on the change in the detection result, the feeder control unit 65 determines that the reel R has been removed.

(2. Configuration of feeder management device 7 of the embodiment)
The description of the feeder management device and the feeder management method of the embodiment will be given. The electronic component mounting machine 1 described above constitutes a board production line together with other board production equipment. A host computer is used to manage the operating status of the board production line. The feeder management device 7 of the embodiment is realized by the software of the host computer. Further, the feeder management method of the embodiment is implemented by the feeder management device 7. FIG. 3 is a functional block diagram illustrating the feeder management device 7 of the embodiment. In FIG. 3, the component supply device 3 of the electronic component mounting machine 1 is simplified, and feeders 6 are provided in each of the five slots 32, that is, the first to fifth slots SL1 to SL5.

The host computer has a production planning management unit 81 and a feeder management unit 82 as functions other than the feeder management device 7. The production plan management unit 81 manages a production plan that defines the production order of a plurality of types of substrates K in a predetermined future period. The production plan management unit 81 updates the production plan sequentially based on the progress of production, the addition of orders for a new type of substrate K, and the like. The production plan includes the required component types of electronic components mounted on a plurality of types of boards K, the slot positions of the feeder 6 for supplying the required component types of electronic components (any of the first to fifth slots SL1 to SL5), and the like. Contains information about.

On the other hand, the component supply control unit 35 of the component supply device 3 acquires the feeder ID code of the equipped feeder 6 from each feeder control unit 65 by communication. As a result, the component supply control unit 35 can store the feeder ID code of each feeder 6 in association with the slot position. Next, the component supply control unit 35 pays attention to the reels R set in each feeder 6 in order, and can acquire the attached reel ID code Rid by using the code reading unit 36. As a result, the component supply control unit 35 can perform a code mapping step of associating and storing the feeder ID code for identifying the feeder and the reel ID code Rid for identifying the reel. In the feeder 6 that holds the used reel R in advance, the code mapping step is already performed when the feeder 6 holds the reel R, so that the code mapping step is not necessary again. The component supply control unit 35 can store the current component type of the electronic component supplied by the feeder 6 currently equipped and the slot position of the feeder 6 equipped in association with each other.

Information relating the feeder ID code and the reel ID code Rid and information relating the current component type of the electronic component to the slot position of the feeder 6 are delivered from the component supply control unit 35 to the feeder management unit 82. .. The feeder management unit 82 manages not only the information delivered from the parts supply control unit 35 but also the information from another parts supply control unit and the information delivered in the past. That is, the feeder management unit 82 also manages the feeder 6 used in another electronic component mounting machine and the feeder 6 that has been temporarily removed.

The host computer has the functions of the current state storage unit 71, the planned storage unit 72, the reel removal guide unit 73, the feeder removal guide unit 74, the current status maintenance guide unit 75, the re-equipment guide unit 76, and the guide display unit as the functions of the feeder management device 7. Has 77. The guidance display unit 77 is hardware such as a display device that displays guidance contents to the operator. Each unit 71 to 76 other than the guidance display unit 77 is realized by using software. The functions of each unit 71 to 76 other than the guidance display unit 77 are shown in the feeder management method of the embodiment described below.

(3. Feeder management method of the embodiment)
FIG. 4 is a diagram of a processing flow for explaining the feeder management method of the embodiment. This processing flow is executed for the convenience of setup change work when the production of the substrate K of a certain substrate type is completed and the production is transferred to the next substrate type. In the current state storage step S1 of FIG. 4, the current state storage unit 71 associates the current state component type of the electronic component supplied by the currently equipped feeder 6 with the slot position of the equipped feeder 6. Remember. The current state storage unit 71 acquires necessary information from the feeder management unit 82. In the next planning storage step S2, the planning storage unit 72 associates the required component types of the electronic components mounted on the plurality of types of boards K with the slot positions of the feeder 6 for supplying the required component types of the electronic components. And remember. The plan storage unit 72 acquires necessary information from the production plan management unit 81.

FIG. 5 is a diagram of a list illustrating the information stored in the current state storage step S1 and the planned storage step S2 shown in FIG. In the figure, F1 to F8 indicate the individual feeder 6, and P1 to P8 in parentheses indicate the distinction between the component types of the electronic components. In this example, the production order of the substrate K is simplified from the first to the fourth, and the types of the substrate K to be produced are four types of substrate types B1 to B4. Further, the slots 32 are simplified to five locations of the first to fifth slots SL1 to SL5, and the types of electronic components mounted on the substrate K of one substrate type are simplified to five or less. Now, it is assumed that the production of the substrate K of the substrate type B1 having the first production sequence shown in FIG. 5 is completed.

In the first production sequence shown, the feeder F1 was equipped in the first slot SL1, and the electronic parts of the component type P1 were supplied from the feeder F1. Similarly, the feeder F2 was equipped in the second slot SL2, and the electronic components of the component type P2 were supplied from the feeder F2. Further, the feeders F3 to F5 are equipped in the third to fifth slots SL3 to SL5, and the electronic parts of the component types P3 to P5 are supplied from the feeders F3 to F5. The feeder ID codes of the feeders F1 to F5 and the reel ID code Rid of the reel R for supplying the electronic components of the component types P1 to P5 are associated in advance by the code mapping step described above.

Therefore, the current state storage unit 71 stores the current state component type P1 and the first slot SL1 in association with each other. Similarly, the current state storage unit 71 stores the current part type P2 and the second slot SL2 in association with each other, and further associates the current part types P3 to P5 with the third to fifth slots SL3 to SL5, respectively. And remember.

Further, in the second production order, the first slot SL1 and the fifth slot SL5 are planned to be unused. The feeder F2 is equipped in the second slot SL2, and the electronic components of the component type P2 are planned to be supplied from the feeder F2. Similarly, the feeders F6 and F7 are equipped in the third and fourth slots SL3 and SL4, and the electronic components of the component types P6 and P7 are planned to be supplied from the feeders F6 and F7.

Therefore, the planning storage unit 72 stores the required component type P2 and the second slot SL2 in association with each other. Similarly, the planning storage unit 72 stores the required component type P6 and the third slot SL3 in association with each other, and further stores the required component type P7 and the fourth slot SL4 in association with each other.

Similarly, in the third production sequence, the first slot SL1 is planned to be unused. The planning storage unit 72 stores the required component type P2 and the second slot SL2 in association with each other, and stores the required component type P4 and the third slot SL3 in association with each other. Further, the planning storage unit 72 stores the required component type P8 and the fourth slot SL4 in association with each other, and stores the required component type P5 and the fifth slot SL5 in association with each other.

Similarly, in the fourth production sequence, the first slot SL1 and the fifth slot SL5 are planned to be unused. The planning storage unit 72 stores the required component type P2 and the second slot SL2 in association with each other, and stores the required component type P3 and the third slot SL3 in association with each other. Further, the planning storage unit 72 stores the required component type P7 and the fourth slot SL4 in association with each other.

Returning to FIG. 4, in step S3, the feeder management device 7 sets the target slot of interest to the first slot SL1. In the next step S4, the feeder management device 7 determines whether or not the current component type P1 of the first slot SL1 of interest matches any of the required component types. The feeder management device 7 recognizes that the current component type P1 does not match any of the required component types P2 to P8, and advances the processing flow to the reel removal guide step S5.

In the reel removal guide step S5, the reel removal guide unit 73 causes the guide display unit 77 to display a guide for removing the reel from the feeder F1. FIG. 6 is a diagram showing an example of guidance contents in the reel removal guidance step S5, the feeder removal guidance step S8, the status quo maintenance guidance step S23, and the re-equipment guidance step S24. As shown in the figure, the guidance content "Please remove the reel from the feeder F1" is displayed at the position of the first slot SL1 of the guidance display unit 77. Therefore, the operator can start the work of removing the reel R from the feeder F1 without being confused by the setup change work.

Further, the reel removal guide step S5 includes an automatic rewinding step or a manual rewinding step. When the automatic rewinding step is included, the reel removal guide unit 73 selects the automatic rewinding mode and commands the feeder F1 via the component supply control unit 35. As a result, the tape feeding mechanism of the feeder F1 automatically rewinds the carrier tape T to the reel R. When the manual rewinding step is included, the reel removal guide unit 73 selects the manual rewinding mode and commands the feeder F1 via the component supply control unit 35. As a result, in the feeder F1, when the rewind switch 662 is pressed and held for a long time, the tape feeding mechanism continuously rewinds the carrier tape T to the reel R.

In the next step S6, the reel removal guide unit 73 waits for the reel R of the feeder F1 to be removed. The information from which the reel R has been removed is delivered from the tape detection sensor 68 to the reel removal guide unit 73 via the feeder control unit 65, the component supply control unit 35, and the feeder management unit 82. When the reel R is removed, the reel removal guide unit 73 advances the processing flow to the associated deletion step S7. In the association deletion step S7, the reel removal guide unit 73 deletes the association between the feeder ID code of the feeder F1 and the reel ID code Rid of the reel R that supplies the electronic component of the component type P1.

In the next feeder removal guide step S8, the feeder removal guide unit 74 causes the guide display unit 77 to display a guide for removing the feeder F1 from the component supply device 3. As shown in FIG. 6, the guidance content of the position of the first slot SL1 of the guidance display unit 77 is changed and displayed as "Please remove the feeder F1."

Further, the feeder removal guide step S8 includes an information display step. That is, the feeder removal guide unit 74 displays the removal information on the display unit 33 corresponding to the first slot SL1 via the component supply control unit 35. As a result, for example, the LED lamp as the display unit 33 is turned on. Therefore, the operator can visually recognize the removal information of the display unit 33 in the setup change work and start the work of removing the feeder F1 without being confused.

In the next step S9, the feeder removal guide unit 74 waits for the feeder F1 to be removed. The information from which the feeder F1 has been removed is delivered to the feeder removal guide unit 74 via the component supply control unit 35 and the feeder management unit 82. When the feeder F1 is removed, the feeder removal guide unit 74 erases the removal information, turns off the LED lamp, for example, and advances the processing flow to step S10.

In step S10, the feeder management device 7 determines whether or not the processing of all slots has been completed. In the first step S10, since the processing of the first slot SL1 is only completed, the processing flow proceeds to step S11. In step S11, the feeder management device 7 increases the number of the target slot by 1 to pay attention to the second slot SL2, and returns the processing flow to step S4.

In the second step S4, the feeder management device 7 recognizes that the current part type P2 of the second slot SL2 of interest matches the required part type P2 of the second slot SL2 in the second production order. The processing flow proceeds to step S21. In step S21, the feeder management device 7 determines whether or not the current component type P2 is supplied from the same slot next time. Since the current component type P2 is supplied from the same second slot SL2 in the second production sequence next, the feeder management device 7 advances the processing flow to step S22. In step S22, the feeder management device 7 determines whether or not it is necessary to temporarily surrender the second slot SL2 to another required component type. It is clear that this is not necessary, and the feeder management device 7 advances the processing flow to the status quo guidance step S23.

In the status quo guidance step S23, the status quo guidance unit 75 causes the guidance display unit 77 to display guidance for maintaining the current state of the feeder F2. As a result, as shown in FIG. 6, the guidance content "Please maintain the current state of the feeder F2" is displayed at the position of the second slot SL2 of the guidance display unit 77. Therefore, the worker does not get confused by the setup change work. When the status quo guidance step S23 is completed, the feeder management device 7 merges the processing flow with the step S10, pays attention to the third slot SL3 in the step S11, and returns the processing flow to the step S4.

In the third step S4, the feeder management device 7 recognizes that the current part type P3 of the third slot SL3 of interest matches the required part type P3 of the third slot SL3 in the fourth production order. The processing flow proceeds to step S21. In step S21, the feeder management device 7 recognizes that the current component type P3 will be supplied from the same third slot SL3 in the fourth production order next time, and advances the processing flow to step S22. In step S22, the feeder management device 7 recognizes that it is necessary to temporarily surrender the third slot SL3 to the required component types P6 and P4 in the second and third production orders, and advances the processing flow to the re-equipment guidance step S24. ..

In the re-equipment guidance step S24, the re-equipment guidance unit 76 causes the guidance display unit 77 to display the guidance for re-equiping after removing the feeder F3 while the reel is held. As a result, as shown in FIG. 6, at the position of the third slot SL3 of the guidance display unit 77, "the feeder F3 is removed while the reel is held, and the feeder F3 is reattached to the third slot SL3 in the fourth production order. Please do. ”Is displayed. Further, the re-equipment guidance step S24 includes an information display step, and displays the removal information on the display unit 33 corresponding to the third slot SL3. Therefore, the operator can remove the feeder F3 and re-equip it in the fourth production order without being confused by the setup change work. When the re-equipment guidance step S24 is completed, the feeder management device 7 merges the processing flow with the step S10, pays attention to the fourth slot SL4 in the step S11, and returns the processing flow to the step S4.

In the fourth step S4, the feeder management device 7 recognizes that the current part type P4 of the fourth slot SL4 of interest matches the required part type P4 of the third slot SL3 in the third production order. The processing flow proceeds to step S21. As described above, even if the same component type P4 is used, it may be supplied from different slot positions when the substrate type is changed. For example, the mounting operation optimization technique may be used to optimize the arrangement order of the feeders 6 on the component supply device 3, that is, the arrangement order of the component types for each type of the substrate K. In this case, the third slot SL3 in the center in the width direction of the component supply device 3 is closest to the substrate K and the component recognition camera 5, and the mounting operation is performed in a short time. On the other hand, as the component supply device 3 approaches the slot at the end in the width direction, the mounting operation takes a long time. Therefore, when a large number of required component types P4 are mounted in the third board type B3 in the production order, the supply position of the component type P4 is changed from the fourth slot SL4 to the third slot SL3, and the mounting operation is optimized. ..

In step S21, the feeder management device 7 recognizes that the current component type P4 is supplied from the third slot SL3, which is different in the third production order, and advances the processing flow to the re-equipment guidance step S24. In the re-equipment guidance step S24, the re-equipment guidance unit 76 provides guidance to the guidance display unit 77 to remove the feeder F4 while the reel is held and to re-equip it later. As a result, as shown in FIG. 6, at the position of the fourth slot SL4 of the guidance display unit 77, "the feeder F4 is removed while the reel is held, and the feeder F4 is reattached to the third slot SL3 in the third production order. Please do. ”Is displayed. Further, the re-equipment guidance step S24 includes an information display step, and displays the removal information on the display unit 33 corresponding to the fourth slot SL4. Therefore, the operator can remove the feeder F4 and re-equip it in the third production order without being confused by the setup change work. When the re-equipment guidance step S24 is completed, the feeder management device 7 merges the processing flow with the step S10, pays attention to the fifth slot SL5 in the step S11, and returns the processing flow to the step S5.

In the fifth step S4, the feeder management device 7 recognizes that the current part type P5 of the fifth slot SL5 of interest matches the required part type P5 of the fifth slot SL5 in the third production order. The processing flow proceeds to step S21. In step S21, the feeder management device 7 recognizes that the current component type P5 is supplied from the same fifth slot SL5 in the third production order, and advances the processing flow to step S22. In step S22, the feeder management device 7 may continue to occupy the fifth slot SL5 because the fifth slot SL5 is unused in the second production order and does not need to be temporarily surrendered to other necessary component types. Can be recognized. Therefore, the feeder management device 7 advances the processing flow to the status quo guidance step S23.

In the status quo guidance step S23, the status quo guidance unit 75 causes the guidance display unit 77 to display guidance for maintaining the current state of the feeder F5. As a result, as shown in FIG. 6, the guidance content "Please maintain the current state of the feeder F5" is displayed at the position of the fifth slot SL5 of the guidance display unit 77. The feeder F5 is installed in the fifth slot SL5 in the second production order but is not used, but is used in the third production order.

When the status quo guidance step S23 is completed, the feeder management device 7 merges the processing flow with the step S10. Here, since the processing of all the slots has been completed, the feeder management device 7 ends the processing flow.

Next, assuming the time when the production of the substrate K of the second substrate type B2 in the production order is completed, it is assumed that the order of the new type of substrate K is not added. At this time, the guidance display unit 77 displays the guidance content shown in FIG. 7. FIG. 7 is a diagram showing another example of the guidance content.

When the production order is changed from the second to the third, the first slot SL1 remains unused. Therefore, the guidance content "Unused" is displayed at the position of the first slot SL1 of the guidance display unit 77. In the second slot SL2, the supply of the component type P2 from the feeder F2 is continued. Therefore, the guidance content "Please maintain the current state of the feeder F2" is displayed at the position of the second slot SL2 of the guidance display unit 77.

Further, in the third slot SL3, the supply of the component type P6 from the feeder F6 has ended, and there is no plan to use it thereafter. Therefore, the guidance content "Please remove the reel from the feeder F6" is displayed at the position of the third slot SL3 of the guidance display unit 77. At this time, an automatic rewind step or a manual rewind step is performed. Then, when the reel R is actually removed, the guidance content is changed and displayed as "Please remove the feeder F6." Further, the information display step displays the removal information on the display unit 33 corresponding to the third slot SL3.

In the fourth slot SL4, the part type P7 is supplied from the feeder F7, the part type P8 is supplied from the feeder F8 in the third production order, and the part type P7 is supplied again from the feeder F7 in the fourth production order. It has become. That is, the component type P7 of the feeder F7 needs to temporarily surrender the fourth slot SL4 to another required component type. For this reason, the guidance content "Please remove the feeder F7 while the reel is held and re-equip it in the 4th slot SL4 in the 4th production order" at the position of the 4th slot SL4 of the guidance display unit 77. Is displayed. In addition, the information display step displays the removal information on the display unit 33 corresponding to the fourth slot SL4.

In the fifth slot SL5, the feeder F5 equipped in an unused state is used in the third production order. Therefore, the guidance content "Please maintain the current state of the feeder F5" is displayed at the position of the fifth slot SL5 of the guidance display unit 77.

In this way, even when the production of the board K of the board type B2 is finished, the feeder management device 7 guides the removal of the reel R, the removal guidance of the feeder 6, the guidance for maintaining the status quo, and the guidance for re-equipment for each slot position. Can be done properly. In addition, an automatic rewinding step or a manual rewinding step is used in combination with the reel R removal guide, and an information display step is used in combination with the feeder 6 removal guide. Therefore, the worker does not get confused by the setup change work, and the work efficiency is significantly improved.
