Abstract

PROBLEM TO BE SOLVED: To provide a feeder management method that appropriately guides attachment/detachment of a feeder and removal of a reel on the basis of a production plan to improve work efficiency.

SOLUTION: With a management method of a feeder that holds an electronic component and is detachably mounted at a plurality of arrangement positions of an electronic component mounting machine, data associating a current component type of a mounted electronic component and its arrangement position is acquired. A production plan is acquired including information on a necessary component type of an electronic component to be used afterwards and information of an arrangement position where the necessary component type is supplied. On the basis of the acquired data and the production plan, a state of use after current component type is grasped. When the current component type is not used in a next substrate type and supplied from a different arrangement position in the next substrate type and thereafter, guidance is conducted such that the feeder that supplies the electronic component of the current component type is removed and rearranged at a different arrangement position thereafter. At the same time, information that specifies the feeder and the arrangement position to be reinstalled are guided.

Description

The present specification relates to a feeder management method and a feeder management apparatus for producing substrates based on a production plan that defines the production order of multiple types of substrates.

Equipment for producing boards on which many electronic components are mounted includes solder printing machines, electronic component mounting machines, reflow machines, board inspection machines, and the like. It is common to connect these board production facilities to form a board production line. Among them, the electronic component mounting machine includes a board transfer device, a component supply device, a component transfer device, and a control device. 2. Description of the Related Art As a representative example of a component supply device, there is known a configuration in which a plurality of feeders for feeding out carrier tapes holding a plurality of electronic components are detachably arranged in line.

In recent years, with the diversification of consumer needs, there has been a trend toward high-mix, low-volume production, and there have been cases in which boards are produced based on a production plan that defines the order in which multiple types of boards are to be produced. In this case, when changing the type of substrate, a setup change operation is performed to change the type of electronic components to be supplied from the component supply device. As a method of changing the type of parts, 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 previously held in the replacement feeder, and the replacement feeder is installed in the changeover work. In general, the correspondence between reels and feeders is often managed by associating ID codes attached to them. Technical examples relating to this type of feeder management method are disclosed in Patent Literatures 1 and 2.

The chip component supply device of Patent Document 1 includes a reel holding portion that exchangeably holds a reel around which a carrier tape is wound, a rod-shaped member that holds the reel holding portion at one end, and a carrier that is arranged at the other end of the rod-shaped member. It comprises a reel feeding means for feeding the tape, a reel guide section for taking in the carrier tape and separating it into the component storage tape and the top tape, and a take-up reel for winding the top tape. According to the description of the embodiment, when replacing the tape, the reel is rotated in the reverse direction to rewind the used tape and the top tape, and the reel guide section is moved to the outside of the electronic component mounting machine to perform the replacement work. According to this, it is said that even in situations where the reel is half-used and frequently replaced, the replacement work can be made more efficient, speeding up the work and reducing costs.

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 board type currently being produced will be used for the next and subsequent board types, and a feeder control method based on the determination result. The feeder manager performs two steps during the execution of the current production job. Further, the guiding step maintains the feeder in the current loading slot when the current component type is used for the next board type and moves the feeder to an empty slot or the current slot when the current component type is used for the next and subsequent board types. When the current part type is used in another electronic component placement machine, the feeder is stored in the placement machine shelf, and when the current part type is no longer used, the feeder is placed in the warehouse shelf. A message indicating that the data should be stored is displayed. 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 to quickly start the work.

JP-A-2000-261191 JP 2011-199217 A

By the way, the feeder management method of Patent Literature 2 is a technique for determining whether or not a feeder needs to be removed during setup change work, and in addition, for guiding the storage location of the removed feeder. Here, as the trend toward high-mix, low-volume production progresses, the number of types of electronic components will increase, greatly exceeding the number of feeders on hand, and setup changes will occur frequently. As a result, the frequency of the reel replacement work exemplified in Patent Document 1 increases. However, the technology of Patent Document 2 does not include any description of the reel replacement work, and the operator is at a loss as to whether or not it is better to remove the reel from the feeder. In the past, in order to make this determination accurately, it was necessary to take the trouble of investigating the production plan and confirming whether or not the electronic component was scheduled to be used.

In addition, it is common to optimize the arrangement order of the feeders on the component supply device, that is, the arrangement order of the component types, for each type of board using a mounting operation optimization technique. At this time, even if the feeder is used continuously, the position of the mounting slot may be changed. In addition, it is difficult to know whether feeders used before and after certain types of substrates are idle and can continue to occupy loading slots during the idle period. Considering such a usage pattern of the feeder, it cannot be said that the guiding step of Patent Document 2 is necessarily appropriate and sufficient.

Therefore, it is an object of the present specification to provide a feeder management method and a feeder management device that appropriately guide the attachment and detachment of the feeder and the removal of the reel based on the production plan and improve the work efficiency.

The present specification is a feeder management method that exchangeably holds reels on which carrier tapes for holding electronic components are wound and that are detachably mounted at a plurality of arrangement positions of an electronic component mounting machine, In a guide step of providing guidance regarding the feeder used in the production of a certain board type when production of a board of a certain board type is finished and production of the next board type is started, the feeder supplies the board. When the current component type of the electronic component that was previously used is supplied from the same arrangement position in the production of the next board type, guidance is provided to maintain the current state of the feeder, and the current component type is changed to the next and subsequent component types. When the reel is not used in the production of the board type, guidance is provided to remove the reel from the feeder, and when the current component type is supplied from the different arrangement position in the production of the board type after the next, Guidance is provided to remove the feeder while holding the reel and to re-equip it later, and information indicating the individual of the feeder concerned, the current arrangement position, and the arrangement position to be re-equipped are provided. A feeder management method is disclosed.

Further, the present specification relates to a feeder management device that replaceably holds a reel around which a carrier tape for holding electronic components is wound, and is detachably mounted at a plurality of arrangement positions of an electronic component mounting machine. a guide unit that guides the feeder used for the production of a certain board type when the production of the board of a certain board type is finished and the production of the next board type is shifted to the next board type, The section performs guidance to maintain the current state of the feeder when the current component type of the electronic component supplied by the feeder is supplied from the same arrangement position in the production of the next board type, When the current component type is not used in the production of the next and subsequent board types, guidance is provided to remove the reel from the feeder, and the current component type is different in the production of the next and subsequent board types. When the feeder is supplied from the position, the feeder is removed with the reel held and is guided to be re-equipped later, and information indicating the individual of the feeder concerned, the current arrangement position, and the re-installation are provided. Disclosed is a feeder management device that guides the arrangement position to be equipped.

In the feeder management method and the feeder management device disclosed in this specification, the current part types of electronic parts that can be currently supplied are compared with the part types that will be required in subsequent production planning, and the current part types are determined as follows. Provide guidance to maintain the current state of the feeder when fed from the same placement location. Also, if the current component type is not used in the production of subsequent board types, guidance is provided to remove the reel from the feeder. Furthermore, when the current component type is supplied from a different arrangement position in the production of the next and subsequent board types, the guide to remove the feeder while holding the reel and re-equip it later at the different arrangement position. I do. Therefore, the worker can perform the work according to the guidance without being confused, and the work efficiency is improved.

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

The substrate conveying device 2 is arranged on the upper surface of the machine stand 9, conveys the substrate K in the X direction, and positions it at the mounting position. The substrate transport device 2 is composed of a pair of guide rails 21, a pair of conveyor belts 22, a clamp device 23, and the like. A pair of guide rails 21 extend in the X direction and are arranged parallel to each other. The pair of conveyor belts 22 are ring-shaped on which the substrate K can be placed, and are rotatably provided inside the guide rails 21 facing each other. The clamp device 23 is arranged below the mounting position set in 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 rails 21 and is positioned and fixed at the mounting position by the clamp device 23 .

The component supply device 3 is composed of a substantially rectangular pallet member 31 as a main member. A plurality of slots 32 extending in the Y direction and arranged in the X direction are formed on the upper surface of the pallet member 31 . The slot position where the slot 32 is formed corresponds to the arrangement position where the feeder 6 is installed. A display portion 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, but is not limited to this. The component supply device 3 is detachably equipped with a plurality of feeders 6 in a plurality of slots 32, respectively. The component supply device 3 has a display unit 33 and a component supply control unit 35 (shown in FIG. 3) that controls the feeder 6 provided.

The feeder 6 exchangeably holds the reel R 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 pairs of slots 32 and indicators 33 . Feeders 6 are provided in six slots 32 in total, two on the right side and four on the left side 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 extends in the Y direction above the substrate transfer device 2 and is arranged parallel to each other. The head moving rail 42 extends in the X direction, and both ends thereof are movably supported by the fixed rails 41 . The head moving rail 42 is driven in the Y direction by a ball screw feed 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 a ball screw feed mechanism (not shown). The mounting head 43 has a suction nozzle 44 and a board recognition camera 45 facing downward. The suction nozzle 44 picks up an electronic component from the feeder 6 by suction, and attaches it to the substrate K positioned. The board recognition camera 45 recognizes the correct coordinate position of the board K that has been positioned.

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 explaining one configuration example of the feeder 6. As shown in FIG. The feeder 6 is constructed by attaching a reel holding shaft 61 , a tape guide member 62 , a sprocket 63 , a drive motor 64 , a feeder control section 65 , an operation panel 66 , a tape detection sensor 68 and the like to side plates 69 . The reel holding shaft 61 is provided on the lower rear side of the side plate 69 . The reel holding shaft 61 exchangeably holds a reel R around which a carrier tape T holding electronic components is wound. In this embodiment, it is assumed that the reel R of the reel holding shaft 61 can be replaced while the feeder 6 is installed in the slot 32 . The structure is not limited to this, and the structure may be such that the feeder 6 is removed from the slot 32 and the reel R of the reel holding shaft 61 is replaced.

A reel ID code Rid attached to each reel R is read by the code reading section 36 (shown in FIGS. 1 and 3) of the component supply device 3 and recognized by the component supply control section 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 component type of the electronic component supplied from the carrier tape T wound around the reel R can be identified by the reel ID code Rid.

The tape guide member 62 extends obliquely forward and upward from the front side of the held reel R, and extends horizontally forward after reaching the upper edge of the side plate 69 . The tape guide member 62 guides the carrier tape T unwound from the reel R to the component supply position 67 on the upper front side. A sprocket 63 is journalled on the front lower side of the tape guide member 62 . The teeth on the outer circumference of the sprocket 63 are engaged with the sprocket holes of the carrier tape T. As shown in FIG. The drive motor 64 can rotate the sprocket 63 in both forward and reverse directions. The drive motor 64 is controlled by the feeder control section 65 .

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

The operation panel 66 is provided on the upper surface of the side plate 69 near the rear. The operation panel 66 has a feed switch 661 and a rewind switch 662 . A feeding switch 661 and a rewinding switch 662 are manual switches operated by an operator, and their operating conditions are transmitted to the feeder control section 65 . When the feeding switch 661 or the rewinding switch 662 is pushed, the sprocket 63 of the tape feeding mechanism is intermittently driven forward or reverse. As a result, the carrier tape T is fed out or rewound little by little.

During normal operation, the function of the operation panel 66 is regulated, and the tape feeding mechanism feeds the carrier tape T by pitch feeding and sequentially supplies the electronic components to the component feeding position 47 . On the other hand, the function of the operation panel 66 is used for the changeover work when changing the type of the board K to be 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 presses the feeding switch 661 . As a result, the tape feeding mechanism feeds out 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 mode of operation is the automatic rewind mode, in which the functions of the operation panel 66 are not used. In the automatic rewind mode, the tape feeding mechanism automatically rewinds the carrier tape T onto the reel R. A second mode of operation is a manual rewind mode, in which the functions of the operation panel 66 are used. In the manual rewind mode, the tape feeding mechanism is allowed to rewind the carrier tape T continuously onto the reel R when the rewind switch 662 is held down. This facilitates the work of removing the reel R.

The automatic rewind mode is selected in an automatic rewind step, which will be described later, and the manual rewind mode is selected in a manual rewind step, which will be described later. Only one of the automatic rewinding mode and the manual rewinding mode may be fixed according to the model of the feeder 6 .

The tape detection sensor 68 is arranged on the inclined portion of the tape guide member 62 closer to the rear side. The tape detection sensor 68 detects the presence or absence of the carrier tape T to be fed out and sends the detection result to the feeder control section 65 . Even if the carrier tape T is rewound by the tape feeding mechanism during the replacement work of the reel R, the tip of the carrier tape T returns only up to the sprocket 63. - 特許庁Thereafter, when the operator rewinds the leading end of the carrier tape T to the reel R, the detection result of the tape detection sensor 68 changes from "tape present" to "tape absent". Based on this change in detection result, the feeder control section 65 determines that the reel R has been removed.

(2. Configuration of Feeder Management Device 7 of Embodiment)
The description of the feeder management device and the feeder management method of the embodiment will now proceed. 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 software of the host computer. Also, 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 five slots 32, that is, the first to fifth slots SL1 to SL5.

The host computer has a production plan management section 81 and a feeder management section 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 multiple types of substrates K in a predetermined future period. The production plan management unit 81 sequentially updates the production plan based on the progress of production, the addition of an order for a new type of board K, and the like. The production plan includes the required types of electronic components to be mounted on a plurality of types of boards K, the slot positions of the feeder 6 that supplies the required electronic component types (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 feeder 6 installed from each feeder control unit 65 by communication. Thereby, the component supply control unit 35 can store the feeder ID code of each feeder 6 and the slot position in association with each other. Next, the component supply control unit 35 can sequentially focus on the reels R set on each feeder 6 and acquire the attached reel ID code Rid using the code reading unit 36 . Thereby, the component supply control unit 35 can perform a code association step of correlating 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 previously holds the reel R that is in use, the code association step has already been performed when the feeder 6 holds the reel R, so the code association step is not necessary again. The component supply control unit 35 can associate and store the current component types of the electronic components supplied by the feeders 6 that are currently equipped and the slot positions of the feeders 6 that are currently equipped.

Information that associates the feeder ID code with the reel ID code Rid and information that associates the current component type of the electronic component with the slot position of the feeder 6 are sent from the component supply control unit 35 to the feeder management unit 82. . The feeder management unit 82 collectively manages not only information delivered from the component supply control unit 35, but also information from other component supply control units and information delivered in the past. In other words, the feeder management unit 82 also manages the feeder 6 used in another electronic component mounting machine and the feeder 6 temporarily removed.

As the functions of the feeder management device 7, the host computer includes a current storage unit 71, a plan storage unit 72, a reel removal guide unit 73, a feeder removal guide unit 74, a current maintenance guide unit 75, a re-equipment guide unit 76, and a guide display unit. 77. The guidance display unit 77 is hardware such as a display device that displays guidance contents for the operator. Each unit 71 to 76 other than the guidance display unit 77 is implemented using software. The functions of the sections 71 to 76 other than the guidance display section 77 are shown in the feeder management method of the embodiment described below.

(3. Feeder management method of 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 production of a board K of a certain board type is completed and the production of the next board type is shifted to. 4, the current state storage unit 71 associates the current component types of the electronic components supplied by the feeders 6 currently equipped with the slot positions of the feeders 6 currently equipped. Remember. The current storage unit 71 acquires necessary information from the feeder management unit 82 . In the next plan storage step S2, the plan storage unit 72 associates the required component types of electronic components mounted on a plurality of types of boards K with the slot positions of the feeder 6 that supplies the required component types of the electronic components. memorize. The plan storage unit 72 acquires necessary information from the production plan management unit 81 .

FIG. 5 is a list showing an example of information stored in the current state storage step S1 and the plan storage step S2 shown in FIG. F1 to F8 in the figure indicate individual feeders 6, and P1 to P8 in parentheses indicate the types of electronic components. In this example, the production order of the substrates K is simplified to 1st to 4th, and the types of the substrates K to be produced are 4 substrate types B1 to B4. In addition, the number of slots 32 is simplified to five slots, i.e., first to fifth slots SL1 to SL5, thereby simplifying the types of electronic components to be mounted on the board K of one board type to five types or less. Assume now that the production of the board K of the first board type B1 in the order of production shown in FIG. 5 is completed.

In the illustrated first production sequence, the first slot SL1 was equipped with the feeder F1, and the electronic component of the component type P1 was supplied from the feeder F1. Similarly, the second slot SL2 is equipped with a feeder F2, and electronic components of the component type P2 are supplied from the feeder F2. Further, feeders F3 to F5 are installed in the third to fifth slots SL3 to SL5, and electronic components of 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 codes Rid of the reels R supplying the electronic components of the component types P1 to P5 are associated in advance by the code association step described above.

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

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

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

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

Further, similarly, in the fourth production order, the first slot SL1 and the fifth slot SL5 are planned to be unused. The plan storage unit 72 associates and stores the required component type P2 with the second slot SL2, and associates and stores the required component type P3 with the third slot SL3. Furthermore, the plan storage unit 72 associates and stores the required part type P7 and the fourth slot SL4.

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 part type P1 of the first slot SL1 of interest matches any of the required part types. The feeder management device 7 recognizes that the current part type P1 does not match any of the required part types P2 to P8, and advances the processing flow to reel removal guidance step S5.

In the reel removal guidance step S5, the reel removal guidance section 73 causes the guidance display section 77 to display guidance 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 guidance step S23, and the re-equipment guidance step S24. As shown in the figure, the guidance display section 77 displays the guidance content "Please remove the reel from the feeder F1" at the position of the first slot SL1. Therefore, the operator can start the work of removing the reel R from the feeder F1 without being confused in the setup change work.

Also, the reel removal guidance step S5 includes an automatic rewinding step or a manual rewinding step. When the automatic rewinding step is included, the reel removal guide section 73 selects the automatic rewinding mode and issues a command to the feeder F1 via the component supply control section 35 . As a result, the tape feeding mechanism of the feeder F1 automatically rewinds the carrier tape T onto the reel R. When the manual rewinding step is included, the reel removal guide section 73 selects the manual rewinding mode and issues a command to the feeder F1 via the component supply control section 35 . Thus, in the feeder F1, the tape feeding mechanism continuously rewinds the carrier tape T onto the reel R when the rewind switch 662 is pressed long.

In the next step S6, the reel removal guide section 73 waits until the reel R of the feeder F1 is removed. Information that the reel R has been removed is sent from the tape detection sensor 68 to the reel removal guide section 73 via the feeder control section 65 , the component supply control section 35 and the feeder management section 82 . When the reel R is removed, the reel removal guide section 73 advances the processing flow to the association deletion step S7. In the association deletion step S7, the reel removal guide section 73 deletes the association between the feeder ID code of the feeder F1 and the reel ID code Rid of the reel R supplying the electronic component of the component type P1.

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

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

In the next step S9, the feeder removal guide section 74 waits for the feeder F1 to be removed. Information that the feeder F1 has been removed is sent to the feeder removal guide section 74 via the component supply control section 35 and the feeder management section 82 . When the feeder F1 is removed, the feeder removal guide section 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 processing for all slots has been completed. In step S10 of the first time, the processing flow proceeds to step S11 because the processing of the first slot SL1 is only completed. In step S11, the feeder management device 7 increments the target slot number by 1, focuses on 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 that is second in the production order, The processing flow proceeds to step S21. In step S21, the feeder management device 7 determines whether or not the current part type P2 will be supplied from the same slot next time as well. Since the current part type P2 is second in the next production sequence and is supplied from the same second slot SL2, the feeder management device 7 advances the processing flow to step S22. In step S22, the feeder management device 7 determines whether or not the second slot SL2 needs to be temporarily vacated for other required component types. Clearly, there is no need for this, and the feeder management device 7 advances the processing flow to the status quo guidance step S23.

In the current state maintenance guidance step S23, the current state maintenance guidance section 75 causes the guidance display section 77 to display guidance to maintain the current state of the feeder F2. As a result, as shown in FIG. 6, the guidance content "Keep the current state of feeder F2" is displayed at the position of the second slot SL2 of the guidance display section 77. Therefore, the operator does not get confused in the setup change work. When the status maintenance guidance step S23 ends, the feeder management device 7 joins the processing flow to step S10, focuses on the third slot SL3 in step S11, and returns the processing flow to 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 fourth in the production order, The processing flow proceeds to step S21. In step S21, the feeder management device 7 recognizes that the current part type P3 is the fourth in the production sequence and will be supplied from the same third slot SL3 next time, and advances the processing flow to step S22. In step S22, the feeder management device 7 recognizes that the third slot SL3 needs to be temporarily surrendered to the required part types P6 and P4 in the second and third production order, and advances the processing flow to re-equipment guidance step S24. .

In the re-equipment guide step S24, the re-equipment guide section 76 causes the guide display section 77 to display a guide to remove the feeder F3 with the reel held and to re-equip it later. As a result, as shown in FIG. 6, at the position of the third slot SL3 of the guidance display portion 77, the message "Feeder F3 is removed with the reel held and re-equipped in the third slot SL3 at the fourth production order." Please do so." is displayed. In addition, the re-equipment guidance step S24 includes an information display step, in which removal information is displayed on the display section 33 corresponding to the third slot SL3. Therefore, the operator can remove the feeder F3 and re-equip it at the 4th position in the production order without being embarrassed by the changeover work. When the re-equipment guidance step S24 ends, the feeder management device 7 joins the processing flow to step S10, focuses on the fourth slot SL4 in step S11, and returns the processing flow to 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, which is the third in the production order, and The processing flow proceeds to step S21. In this way, even the same component type P4 may be supplied from different slot positions when the board type is changed. For example, there is a case where the arrangement order of the feeders 6 on the component supply device 3, ie, the arrangement order of the component types, is optimized for each type of board K using a mounting operation optimization technique. In this case, the third slot SL3 in the center of the component supply device 3 in the width direction is closest to the board K and the component recognition camera 5, and the mounting operation is performed in a short time. On the other hand, the closer the slot at the end of the width direction of the component supply device 3 is, the longer the mounting operation takes. Therefore, when a large number of necessary component types P4 are mounted on the board type B3 that is third in the production order, the supply position of the component type P4 is changed from the fourth slot SL4 to the third slot SL3, thereby optimizing the mounting operation. .

At step S21, the feeder management device 7 recognizes that the current part type P4 is the third in the production sequence and is supplied from the different third slot SL3, and advances the processing flow to the re-equipment guidance step S24. In the re-equipment guide step S24, the re-equipment guide section 76 instructs the guidance display section 77 to remove the feeder F4 with the reel 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 section 77, the message "Feeder F4 is removed with the reel held and re-equipped to the third slot SL3 in the third production order" is displayed. Please do so." is displayed. Further, the re-equipment guidance step S24 includes an information display step, in which removal information is displayed on the display section 33 corresponding to the fourth slot SL4. Therefore, the operator can remove the feeder F4 and re-equip it as the third in the production order without being embarrassed by the changeover work. When the re-equipment guidance step S24 ends, the feeder management device 7 joins the processing flow to step S10, focuses on the fifth slot SL5 in step S11, and returns the processing flow to 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, which is third in the production sequence, and The processing flow proceeds to step S21. In step S21, the feeder management device 7 recognizes that the current part type P5 is the third in the production order and is supplied from the same fifth slot SL5, and advances the processing flow to step S22. In step S22, the feeder management device 7 may set the fifth slot SL5 as unused second in the production order so that the feeder F5 may continue to occupy the fifth slot SL5 without needing to temporarily surrender it to other required component types. can be recognized. Therefore, the feeder management device 7 advances the processing flow to the status maintenance guidance step S23.

In the current state maintenance guidance step S23, the current state maintenance guidance section 75 causes the guidance display section 77 to display guidance to maintain the current state of the feeder F5. As a result, as shown in FIG. 6, the guide content "Keep the feeder F5 in its current state." The feeder F5 is installed in the fifth slot SL5 but is not used in the second production order, but is used in the third production order.

When the status maintenance guidance step S23 ends, the feeder management device 7 joins the processing flow to step S10. Here, since the processing of all slots has been completed, the feeder management device 7 ends the processing flow.

Next, it is assumed that the production of the board K of the board type B2, which is second in the order of production, is completed, and that there is no additional order for the board K of a new type. At this time, the guide display unit 77 displays the guide contents shown in FIG. FIG. 7 is a diagram showing another example of guidance content.

When the production order is changed from the second to the third, the first slot SL1 remains unused. For this reason, the guide content of "unused." In the second slot SL2, the supply of the part type P2 from the feeder F2 is continued. For this reason, the guide content "Keep the feeder F2 in its current state."

Further, in the third slot SL3, the supply of the part type P6 from the feeder F6 is finished, and there is no plan to use it thereafter. For this reason, the guide content of "Please remove the reel from the feeder F6." At this time, an automatic rewinding step or a manual rewinding step is performed. Then, when the reel R is actually removed, the content of the guidance is changed to "Please remove the feeder F6." Furthermore, the removal information is displayed on the display section 33 corresponding to the third slot SL3 by the information display step.

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's becoming In other words, the component type P7 of the feeder F7 needs to temporarily give up the fourth slot SL4 to another required component type. For this reason, at the position of the fourth slot SL4 of the guidance display section 77, there is a guidance content that reads, "Remove the feeder F7 with the reel held, and reinstall it in the fourth slot SL4 in the fourth production order." Is displayed. In addition, the information display step displays removal information on the display unit 33 corresponding to the fourth slot SL4.

In the fifth slot SL5, the feeder F5 installed in an unused state is used as the third in the production order. For this reason, the guide content "Keep the feeder F5 in its current state."

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