Description

The present invention provides a section for arranging a plurality of component types at a plurality of arrangement positions for the purpose of improving production efficiency when arranging feeder devices at a plurality of arrangement positions arranged in a line on a component mounter. The present invention relates to a product type arrangement calculation method.

Equipment for producing boards on which a large number of components are mounted includes solder printers, component mounters, reflow machines, board inspection machines, and the like. It is common to connect these facilities to form a board production line. Among them, the component mounter includes a substrate transfer device, a component supply device, a component transfer device, and a control device. As a representative example of a component supply device, there is a feeder device that feeds out component storage tapes each storing components in a plurality of component storage sections. In combination with this feeder device, a reel holding device is used that rotatably and replaceably holds a component supply reel around which a component storage tape is wound.

A plurality of feeder devices and reel holding devices are arranged at a plurality of arrangement positions arranged in a line on the mounter. A plurality of types of components to be mounted on the board are arranged at a plurality of arrangement positions arranged in a line. At this time, the board production efficiency changes depending on the arrangement order of the plurality of component types. For this reason, techniques have been developed for simulating component type placement in consideration of the movement distance of a mounting head of a component transfer device. In the device placement determination method of Patent Document 1, the management device determines the placement of the plurality of feeder devices so that the mounting cycle time (takt time) required to produce one substrate is minimized. At this time, the difference in the types of the plurality of feeder devices, the condition of the types of parts that can be supplied, and the like are taken into consideration (see paragraphs 0026 and 0027 of Patent Document 1, etc.).

JP 2009-130337 A

By the way, in order to change the type of component supplied from the feeder device, it is necessary to replace the component supply reel. At this time, in the conventional feeder device, it is necessary to rewind the used component storage tape to the component supply reel, pull out the new component storage tape from the component supply reel, and load the new component storage tape, which is a troublesome task. . For this reason, in the conventional component type placement techniques including Patent Document 1, in order to realize the simulated arrangement order of the component types, instead of exchanging the component storage tapes, the entire feeder device including the component storage tapes is replaced. were often replaced.

With the above-described conventional method, even if the direct mounting cycle time for producing boards can be shortened, a lot of time is required for setup work when changing the type of board to be produced. Therefore, the technique of Patent Literature 1 cannot necessarily be said to be a good idea. In particular, there is a recent trend toward high-mix low-volume production, which increases opportunities for changeover work. In addition, a large number of feeder units are required for replacement, increasing equipment costs.

Also, recently, an automatic feeder device (so-called auto loading feeder) having an automatic loading function for automatically loading a component storage tape has been developed with the aim of reducing setup change work. In the automatic feeder device, when changing the arrangement order of the component types, the component storage tape is usually replaced, and the entire feeder device is not replaced. Since this type of automatic feeder device has good workability when replacing the component storage tape and is highly convenient, it is desirable to make effective use of it. Considering the reduction of the setup change work, the increase in equipment cost, and the effective utilization of the automatic feeder device, it is necessary to further improve the component type arrangement technology.

The present invention has been made in view of the above-mentioned problems of the background art, and effectively utilizes an automatic feeder device having an automatic loading function. The problem to be solved is to provide a component type placement calculation method that improves the

A clamp device (not shown) is provided below the conveyor belt at the mounting position. The clamping device pushes up the substrate K, clamps it in a horizontal posture, and positions it at the mounting position. As a result, the component transfer device 14 can perform the mounting operation at the mounting position.

The manual feeder device 7 and the automatic feeder device 9 each feed the parts sequentially. Each feeder device 7, 9 has a flat shape with a small width dimension, and is arranged in rows in first to ninth slots SL1 to SL9 of a common pallet 5 mounted on a machine base 19 (details will be described later). In FIG. 1, automatic feeder devices 9 are arranged in the third to seventh slots SL3 to SL7, and manual feeder devices 7 are arranged in the other slots SL1, SL2, SL8 and SL9. Behind the automatic feeder device 9, a reel holding device 6 detachable from the common pallet 5 is arranged. On the other hand, the manual feeder device 7 is integrally provided with a reel holding device. In an actual mounter, more feeder devices 7 and 9 are often arranged in a row.

A pair of Y-axis rails 141 and 142 are arranged near both sides of the machine base 19 and extend in the front-rear direction (Y-axis direction). A Y-axis slider 143 is mounted on the Y-axis rails 141 and 142 so as to be movable in the Y-axis direction. The Y-axis slider 143 is driven in the Y-axis direction by a Y-axis ball screw mechanism (not shown).

The mounting head 144 is mounted on the Y-axis slider 143 so as to be movable in the X-axis direction. The mounting head 144 is driven in the X-axis direction by an X-axis ball screw mechanism (not shown). A nozzle tool 145 is exchangeably held on the mounting head 144 . The nozzle tool 145 has one or a plurality of suction nozzles for picking up components and mounting them on the substrate K. FIG. A substrate camera 146 is provided alongside the nozzle tool 145 on the mounting head 144 . The board camera 146 captures an image of the fiducial mark attached to the board K to detect the correct position of the board K. FIG.

The component camera 15 is provided facing upward at the central position in the width direction of the upper surface of the machine base 19 between the board transfer device 12 and the feeders 7 and 9 . The component camera 15 captures the state of the component sucked by the suction nozzle while the mounting head 144 is moving from the feeder devices 7 and 9 onto the board K. When an error in the pick-up posture of the component, a deviation in the rotation angle, etc., of the component is found from the imaging data of the component camera 15, the control device 16 finely adjusts the component mounting operation as necessary. control to discard

In addition, the control device 16 sequentially collects and updates operation status data such as the number of substrates K whose production has been completed, the mounting time required for component mounting, and the number of occurrences of component pickup errors.

(2. Configuration example of automatic feeder device 9, reel holding device 6, and manual feeder device 7)
Next, configuration examples of the automatic feeder device 9 and the reel holding device 6 will be described. FIG. 2 is a side view showing a configuration example of a usage state in which the automatic feeder device 9 and the reel holding device 6 are mounted on the common pallet 5. As shown in FIG.

The common pallet 5 is detachably mounted on the upper side of the machine base 19. - 特許庁The common pallet 5 is not limited to this, and may be fixedly mounted on the upper side of the machine base 19 . The common pallet 5 has a feeder mounting portion 51 and a reel mounting portion 55 . The feeder mounting portion 51 is formed by providing an upright portion 53 on the front side of a substantially rectangular planar portion 52, and is substantially L-shaped when viewed from the side. Nine first to ninth slots SL1 to SL9 extending in the front-rear direction are engraved in the plane portion 52 so as to be aligned in the width direction. FIG. 1 shows the widthwise positions of the first, fifth and ninth slots SL1, SL5 and SL9. The automatic feeder device 9 is inserted from the rear of the slots SL1 to SL9 toward the front upright portion 53 and installed. The first to ninth slots SL1 to SL9 correspond to positions where the feeder devices 7 and 9 are arranged.

The automatic feeder device 9 has a tape insertion opening 91 near the middle height of the rear end, and an insertion lever 92 near the top of the rear end. By lifting the insertion lever 92, the first and second component storage tapes 85 and 86 can be inserted into the tape insertion opening 91 in order. A delivery rail 93 is arranged from a tape insertion port 91 of the automatic feeder device 9 toward the upper front end. A supply position 94 is set on the upper surface of the feeding rail 93 near the front end. A standby position 96 is set on the upper surface of the delivery rail 93 near the tape insertion opening 91 near the rear. The inserted first and second component storage tapes 85, 86 advance to the standby position 96 and temporarily stop.

A tape control unit 95 is provided above the standby position 96 . The tape control unit 95 allows the first component storage tape 85 to be drawn out from the standby position 96 and makes the second component storage tape 86 stand by. In addition, when the first component storage tape 85 runs out, the tape control unit 95 automatically allows the second component storage tape 86 to be fed out from the standby position 96 . Therefore, splicing work for connecting the first and second component storage tapes 85, 86 is not required. A specific configuration of the tape control unit 95 is disclosed, for example, in JP-A-2014-82454.

Further, the automatic feeder device 9 has a tape feeding mechanism (not shown) composed of a servomotor, a sprocket, and the like. When the first component storage tape 85 is inserted up to the standby position 96, the automatic feeder device 9 rotates the servo motor forward. As a result, the automatic feeder device 9 automatically feeds out and loads the first component storage tape 85, and preparations for the production of the board K are completed. That is, the automatic feeder device 9 has an automatic loading function. The timing for inserting the second component storage tape 86 may be immediately after the first component storage tape 85 is inserted, or may be during production using the first component storage tape 85 .

Further, when the automatic feeder device 9 receives the discharge command, it reversely drives the servomotor. As a result, the automatic feeder device 9 discharges the cut ends of the loaded first or second component storage tapes 85 and 86 from the supply position 94 toward the tape insertion port 91 . That is, the automatic feeder device 9 has an automatic discharge function. The discharge command is issued from the control device 16 or by the operator pressing a discharge button (not shown) attached to the automatic feeder device 9 . The automatic feeder device 9 is provided with a tape control unit 95 and has an automatic loading function and an automatic discharging function, thereby greatly reducing the trouble of reel replacement work. The applicant of the present application has filed detailed configuration examples of the automatic feeder device 9 in International Application JP2014/064443, International Application JP2014/083619, and the like.

The reel mounting portion 55 of the common pallet 5 is composed of two arm members 56, a front transfer plate 57, a rear transfer plate 58, and the like. The reel mounting portion 55 is adapted to mount one or a plurality of reel holding devices 6 . More specifically, the two arm members 56 are fixed to rear portions of the feeder mounting portion 51 on both sides in the width direction. The arm member 56 is formed so as to initially extend horizontally rearward, then obliquely extend rearward and downward, and finally extend horizontally rearward. A front bridging plate 57 is provided to connect the inclined portions of the two arm members 56 . A rear plate 58 is provided to connect the rear horizontal portions of the two arm members 56 . A reel holding device 6 is detachably attached to the upper side of the front transfer plate 57 and the rear transfer plate 58 .

The reel holding device 6 rotatably holds the first and second component supply reels 81 and 82 side by side in the front-rear direction. The reel holding device 6 is not limited in size in the width direction (direction of the reel axis), and holds one or more first and second component supply reels 81 and 82 side by side in the width direction. Therefore, the reel holding device 6 is mounted behind one or a plurality of automatic feeder devices 9 .

When changing the arrangement order of the component types arranged in each of the slots SL1 to SL9 according to the simulation result, the operator replaces the reel holding device 6 arranged behind the automatic feeder device 9, or replaces the first reel holding device 6 and the first reel holding device 6. Only the two-component supply reels 81, 82 are replaced. Subsequently, the operator pulls out the first and second component storage tapes 85 and 86 from the first and second component supply reels 81 and 82 and inserts them from the tape insertion port 91 of the automatic feeder device 9 to the standby position 96 . As a result, the automatic loading function of the automatic feeder device 9 works, and the first and second component storage tapes 85 and 86 are successively delivered to the supply position 94 .

On the other hand, the manual feeder device 7 is integrally provided with a reel holding device and directly holds the component supply reel. When a new component supply reel is set in the reel holding device of the manual feeder device 7 , the operator needs to pull out the component storage tape and load it into the manual feeder device 7 . Therefore, the reel replacement work is troublesome for the operator. When changing the arrangement order of the component types arranged in each of the slots SL1 to SL9 according to the simulation results, the operator normally replaces the entire manual feeder device 7 together with the reel holding device and does not perform reel replacement work. Since the manual feeder device 7 can be configured based on various known techniques, detailed description thereof will be omitted.

(3. Part type arrangement method of the first embodiment)
Next, the component type arrangement method of the first embodiment will be described with reference to FIGS. 3 to 5. FIG. The component type arrangement method of the first embodiment is realized by the arithmetic processing function of a controller (host computer) (not shown) that manages the board production line including the component mounter 1 . The component type arrangement method is not limited to this, and may be implemented by the control device 16 of the component mounter 1 or a separate computer device that shares various data such as mounting sequence data. FIG. 3 is a diagram showing an arithmetic processing flow related to the component type arrangement method of the first embodiment together with work items. Also, FIG. 4 is a diagram of a feeder arrangement table showing an example of the arithmetic processing result obtained in the fixed setting step S1 in the arithmetic processing flow. Furthermore, FIG. 5 is a diagram of a feeder arrangement table showing an example of the arithmetic processing result obtained in the simulation step S4.

As a precondition, it is assumed that the mounter 1 first produces the board K of the first board type B1 and then produces the board K of the second board type B2. Nine types of components of first to ninth component types P1 to P9 are mounted on the board K of the first board type B1, and these nine types of components are supplied from first to ninth component supply reels R1 to R9. be. As usable automatic feeder devices 9, five first to fifth automatic feeder devices ALF1 to ALF5 are prepared, and as manual feeder devices 7, many (n) manual feeder devices M1 to Mn are prepared. The first to seventh part types P1 to P7 can be supplied from any of the first to fifth automatic feeder devices ALF1 to ALF5 and the manual feeder devices M1 to Mn, and the eighth and ninth part types P8 and P9 , can be fed only from the manual feeder devices M1-Mn.

The feeder arrangement tables shown in FIGS. 4 and 5 consist of 10 rows and 4 columns, and the first row shows the display contents of each column. As indicated by the slot numbers in the first column, the second to tenth stages correspond to the first to ninth slots SL1 to SL9, respectively. The second column displays the component types arranged in the first to ninth slots SL1 to SL9. The third column displays the unique names of the feeder devices mounted in the first to ninth slots SL1 to SL9. The fourth column displays the feeder status indicating whether or not the feeder device displayed in the third column is movable. That is, "variable" indicates a state in which movement of the feeder device is permitted, and "fixed" indicates a state in which the feeder device is fixed and movement is prohibited.

In a fixed setting step S1 of FIG. 3, the control device defines a part of the first to ninth slots SL1 to SL9 to fixed positions. The controller sets the first to fifth automatic feeder devices ALF1 to ALF5 to be arranged in fixed positions. In one example of the arithmetic processing result of FIG. 4, the continuous third to seventh slots SL3 to SL7 are determined at fixed positions. The first automatic feeder device ALF1 is arranged in the third slot SL3, the second automatic feeder device ALF2 is arranged in the fourth slot SL4, and so on in order. As a result, the first to fifth automatic feeder devices ALF1 to ALF5 are collectively disposed within the continuous slot range. This setting is performed based on the operator's input setting operation or the like. In general, the automatic feeder device 9, which is advantageous in reducing reel replacement work, is often applied to quickly consumed component types. For this reason, it is often advantageous to dispose the automatic feeder device 9 near the center in the width direction near the component camera 15 and the substrate K, but this is not always the case.

In the next step S2, the operator actually mounts the first to fifth automatic feeder devices ALF1 to ALF5 in the third to seventh slots SL3 to SL7 so as to match the settings.

In the next step S3, the control device sets the first board type B1 of the board to be produced. This setting is performed based on the operator's input setting operation, a board production plan that is input and set in advance, and the like. As a result, it is decided to arrange the first to ninth component types P1 to P9 in the first to ninth slots SL1 to SL9, and the arrangement positions are not decided.

In the next simulation step S4, the control device performs a simulation of arranging the first to ninth component types P1 to P9 in the first to ninth slots SL1 to SL9. That is, the first to ninth component types P1 to P9 are arranged in the first to ninth slots SL1 to SL9 so that their positions can be changed within the range of the constraint conditions, and the mounting cycle time required to produce one board under each arrangement condition. to simulate. Then, the control device adopts the arrangement of the first to ninth component types P1 to P9 that has the shortest mounting cycle time. As a constraint condition, the first to fifth automatic feeder devices ALF1 to ALF5 are not moved from fixed positions in the third to seventh slots SL3 to SL7. Therefore, the eighth and ninth part types P8 and P9 that can be supplied only from the manual feeders M1 to Mn are placed in any of the first, second, eighth and ninth slots SL1, SL2, SL8 and SL9. be done.

In the simulation, the positional relationship between each slot SL1 to SL9, the component camera 15 and the board K, the number of mounting points of each component type P1 to P9 mounted on one board K, the performance of the nozzle tool 145, etc. are taken into consideration. In general, a component type with a large number of mounting points is arranged in the fifth slot SL5 facing the center of the component camera 15 and the board K, but it is not always fixed. As for specific simulation methods, various techniques are publicly known, so a detailed description thereof will be omitted.

The simulation determines the arrangement of the first to ninth component types P1 to P9 in the first to ninth slots SL1 to SL9. In one example of the arithmetic processing result of FIG. 5, the first to fifth part types P1 to P5 are respectively placed in the fifth, fourth, third, sixth and seventh slots SL5, SL4, SL3, SL6 and SL7. placed. As a result, the component types P3, P2, P1, P4 and P5 to be supplied from the first to fifth automatic feeder devices ALF1 to ALF5 are respectively determined.

On the other hand, the sixth to ninth component types P6 to P9 are arranged in the first, second, eighth and ninth slots SL1, SL2, SL8 and SL9, respectively. However, the name of the manual feeder device 7 is not determined. The control device searches for the first manual feeder device M1 in which the sixth component supply reel R6 for supplying the sixth component type P6 is set, and sets it to be placed in the first slot SL1. If there is no manual feeder device 7 on which the sixth component supply reel R6 is set, the control device sets the first manual feeder device M1 capable of setting the sixth component supply reel R6. Similarly, the controller places the second through fourth manual feeder devices M2-M4 feeding the seventh through ninth part types P7-P9 into the second, eighth and ninth slots SL2, SL8 and SL9, respectively. Set to place.

As a result, the feeder arrangement table shown in FIG. 5 is completed. The control device displays the completed feeder layout table to the operator and instructs the work contents of the setup change work.

In step S5, the operator performs setup change work according to the feeder arrangement table. In the setup change work for the first to fifth automatic feeder devices ALF1 to ALF5, the operator sets the component supply reels R3, R2, R1, R4, and R5 corresponding to the component types P3, P2, P1, P4, and P5. It is set in the holding device 6, and the reel holding device 6 is mounted behind each of the automatic feeder devices ALF1 to ALF5.

Here, it is suitable for the reel holding device 6 to rotatably hold the five types of component supply reels R3, R2, R1, R4, and R5 in the listed order. This is because the worker only needs to mount one reel holding device 6 during the changeover work, and the workability is particularly good. In addition, according to the reel holding device 6 that holds a plurality of types of component supply reels 81 and 82 instead of five types, setup change work related to the first to fifth automatic feeder devices ALF1 to ALF5 is reduced.

On the other hand, in the setup change work for the first to fourth manual feeder devices M1 to M4, the operator performs the first, second, eighth, and ninth slots SL1, SL2, and The first to fourth manual feeder devices M1 to M4 are exchanged between SL8 and SL9. Alternatively, the operator sets the sixth to ninth component supply reels R6 to R9 on the reel holding devices of the first to fourth manual feeder devices M1 to M4 outside the component mounter 1. FIG. Then, the operator carries in the first to fourth manual feeder devices M1 to M4 and mounts them in the slots SL1, SL2, SL8 and SL9.

When the changeover work is completed, in step S6, the control device produces the board K of the first board type B1. When the production of the predetermined number of substrates K is completed, the control device returns the execution of the arithmetic processing flow to step S3.

Steps S3, S4, and S5 are performed again prior to production of the next board K of the second board type B2. Even if the board K to be produced is changed from the first board type B1 to the second board type B2, the first to fifth automatic feeder apparatuses ALF1 to ALF5 are not moved from the fixed positions of the third to seventh slots SL3 to SL7. . Then, in response to the change in component type arrangement indicated by the simulation results, only the reel holding device 6 or the component supply reels R1 to R5 are replaced in the first to fifth automatic feeder devices ALF1 to ALF5. On the other hand, the first to fourth manual feeder devices M1 to M4 are exchanged among the first, second, eighth, and ninth slots SL1, SL2, SL8, and SL9 in response to changes in component type arrangement. be. Alternatively, the fifth and subsequent manual feeder devices M5 to Mn are loaded and mounted in the first, second, eighth, and ninth slots SL1, SL2, SL8, and SL9.

(4. Aspects and effects of the first embodiment)
The component type arrangement method of the first embodiment has an automatic loading function of automatically loading the component storage tapes 85 and 86 when the component storage tapes 85 and 86 containing components are inserted into a plurality of component storage units. An automatic feeder device 9, a manual feeder device 7 that does not have an automatic loading function, and a reel holding device 6 that rotatably holds component supply reels 81 and 82 around which component storage tapes 85 and 86 are wound, When arranging in a plurality of arrangement positions (first to ninth slots SL1 to SL9) arranged in rows on a common pallet 5 equipped in the component mounter 1, a plurality of component types P1 to P9 of the components are arranged. A part type arrangement method for arranging components in a plurality of arrangement positions, in which a part of the plurality of arrangement positions (third to seventh slots SL3 to SL7) is determined as a fixed position, and a first to fifth automatic feeder device ALF1 is provided. A fixed setting step S1 for setting to arrange the ALF5 in a fixed position, and the first to fourth manual feeder devices M1 to M4 without moving the first to fifth automatic feeder devices ALF1 to ALF5 from the fixed positions. A plurality of part types P1 to P9 of the parts are provided under the condition that they can be moved to any arrangement position (first, second, eighth, and ninth slots SL1, SL2, SL8, SL9) other than the fixed position. and a simulation step S4 for simulating placement at the arrangement position of the .

According to this, when the substrates K are produced using both the automatic feeder device 9 and the manual feeder device 7, the first to fifth automatic feeder devices ALF1 to ALF5 are placed in fixed positions (the third to seventh slots SL3 to SL7 ) for regular use. Therefore, it is possible to effectively utilize the first to fifth automatic feeder devices ALF1 to ALF5, which have good workability during setup change work. Furthermore, the part type arrangement is simulated under the condition that the first to fifth automatic feeder devices ALF1 to ALF5 are not moved from the fixed positions and the manual feeder device 7 can be moved to any arrangement position other than the fixed position. I made it According to this, when changing the type of component at the fixed position, the first to fifth automatic feeder devices ALF1 to ALF5 are not moved, and only the reel holding device 6 or the component supply reels R1 to R5 are exchanged. It can shorten the replacement work time. On the other hand, when changing the type of parts at an arrangement position other than the fixed position, a changeover work equivalent to the conventional one of exchanging the manual feeder device 7 is performed. This makes it possible to achieve the shortest mounting cycle time. Therefore, the production efficiency can be improved by comprehensively considering the changeover work time and the mounting cycle time.

In addition, since the first to fifth automatic feeder devices ALF1 to ALF5 are used regularly, the number of feeder devices 7 and 9 for replacement is reduced. This reduces equipment costs.

Further, the reel holding device 6 includes first to fifth component supply reels R1 to R5 each wound with a component storage tape used in the first to fifth automatic feeder devices ALF1 to ALF5, or a plurality of types of component supply reels. 81 and 82 are rotatably held. Then, in a fixed setting step S1, the first to fifth automatic feeder apparatuses ALF1 to ALF5 are set so as to be collectively arranged in a continuous range of a plurality of slots (third to seventh slots SL3 to SL7).

According to this, the operator only needs to mount fewer reel holding devices 6 than the number of the first to fifth automatic feeder devices ALF1 to ALF5 at the time of setup change. Therefore, the changeover work for the first to fifth automatic feeder devices ALF1 to ALF5 is further reduced.

The component type placement method of the first embodiment can also be implemented as a component type placement calculation device. This component type arrangement calculation device may be realized by the calculation processing function of a control device (host computer) (not shown) that manages the board production line including the component mounter 1, but is not limited to this. It may be implemented by the control device 16 of the mounter 1 or a separate computer device that shares various data such as mounting sequence data. That is, the component type arrangement arithmetic unit includes an automatic feeder device 9 having an automatic loading function for automatically loading the component storage tapes when the component storage tapes containing components are inserted into a plurality of component storage units, and an automatic A component mounter 1 is equipped with a manual feeder device 7 having no loading function and a reel holding device 6 for rotatably holding component supply reels 81 and 82 around which component storage tapes 85 and 86 are wound. When arranging in a plurality of arrangement positions (first to ninth slots SL1 to SL9) arranged in rows on the common pallet 5, a plurality of part types P1 to P9 of the parts are arranged in a plurality of arrangement positions. A part type arrangement calculation device, which determines a part of a plurality of arrangement positions (third to seventh slots SL3 to SL7) as fixed positions and sets the automatic feeder device 9 to be arranged in the fixed position. The setting unit and the automatic feeder device 9 are not moved from the fixed position, and the manual feeder device 7 is moved to any arrangement position other than the fixed position (first, second, eighth, and ninth slots SL1, SL2, SL8, SL9) can be configured to have a simulation section for simulating placement of a plurality of component types at a plurality of placement positions.

The functions and effects of the component type placement arithmetic device of this embodiment are the same as those of the component type placement method of the first embodiment.

(5. Part type arrangement method of the second embodiment)
Next, a component type arrangement method according to the second embodiment will be described with reference to FIGS. 6 and 7. FIG. The component type arrangement method of the second embodiment is realized by the arithmetic processing function of the control device as in the first embodiment, and the arithmetic processing flow of FIG. 3 is the same. However, the second embodiment differs from the first embodiment in that a plurality of types of automatic feeder devices are used. FIG. 6 is a diagram of a feeder arrangement table showing an example of the arithmetic processing result obtained in the fixed setting step S1 when the arithmetic processing flow of FIG. 3 is executed in the second embodiment. Furthermore, FIG. 7 is a diagram of a feeder arrangement table showing an example of the arithmetic processing result obtained in the simulation step S4 when the arithmetic processing flow of FIG. 3 is executed in the second embodiment.

As a precondition, it is assumed that the mounter 1 first produces the board K of the third board type B3 and then produces the board K of the fourth board type B4. Five types of components of eleventh to fifteenth component types P11 to P15 are mounted on the board K of the third board type B3, and these five types of components are supplied from the eleventh to fifteenth component supply reels R11 to R15. be. The 11th and 12th part types P11 and P12 are classified into the small parts group, the 13th and 14th part types P13 and P14 are classified into the medium size parts group, and the 15th part type P15 is classified into the large parts group.

As feeder devices that can be used, first and second small automatic feeder devices ALS1, ALS2, first and second medium-sized automatic feeder devices ALM1, ALM2, and large automatic feeder device ALL are prepared. The five automatic feeder devices ALS1, ALS2, ALM1, ALM2, and ALL are structurally the same as the automatic feeder device 9 described in the first embodiment, and have dimensions according to the size of the parts to be supplied. has been changed.

The first and second small automatic feeder devices ALS1, ALS2 can supply both the 11th and 12th part types P11, P12 belonging to the small parts group. The first and second medium-sized automatic feeder devices ALM1 and ALM2 can supply both the 13th and 14th part types P13 and P14 belonging to the medium-sized parts group. The large automatic feeder device ALL can supply the fifteenth part type P15 belonging to the large parts group. However, each of the automatic feeder devices ALS1, ALS2, ALM1, ALM2, and ALL cannot supply separate groups of component types with different sizes.

In the fixed setting step S1 in the second embodiment, the control device defines the third to seventh slots SL3 to SL7 as fixed positions for each type of automatic feeder device. Then, the control device sets the three types of automatic feeder devices ALS1, ALS2, ALM1, ALM2, and ALL to be arranged at fixed positions for each type. In one example of the arithmetic processing result of FIG. 6, the fourth and fifth slots SL4 and SL5 are determined at the fixed positions for the small size, and the arrangement of the first and second small size automatic feeder devices ALS1 and ALS2 is set. Also, the sixth and seventh slots SL6 and SL7 are set at fixed positions for the medium size, and the arrangement of the first and second medium size automatic feeder devices ALM1 and ALM2 is set. Furthermore, the third slot SL3 is set at a fixed position for the large size, and the arrangement of the large size automatic feeder device ALL is set.

In the next step S2, the operator actually mounts five automatic feeder apparatuses ALL, ALS1, ALS2, ALM1, and ALM2 to the third to seventh slots SL3 to SL7 so as to match the settings.

In the next step S3, the control device sets the third board type B3 of the boards to be produced. As a result, it is decided to arrange the 11th to 15th component types P11 to P15 in the 3rd to 7th slots SL3 to SL7. Then, it is determined that the large fifteenth component type P15 is arranged in the third slot SL3 to which the large automatic feeder device ALL is fixed. The other 11th to 14th part types P11 to P14 are not determined up to the arrangement position.

In the next simulation step S4, the control device arranges the 11th to 14th part types P11 to P14 in the 4th to 7th slots SL7 to SL7 so that their positions can be changed within the range of the constraint conditions. Simulate the mounting cycle time required for production of one sheet. The control device adopts the arrangement of the 11th to 14th component types P11 to P14 that provides the shortest mounting cycle time. As a constraint, the four automatic feeder devices ALS1, ALS2, ALM1, and ALM2 of small size and medium size are not moved from fixed positions in the fourth to seventh slots SL4 to SL7.

Due to the constraints, the eleventh part P11 is placed in the fourth slot SL4 and the twelfth small part P12 is placed in the fifth slot SL5, whereas the eleventh part P11 is placed in the fifth slot SL5. However, there are two possible cases where the twelfth component P12 is arranged in the fourth slot SL4. Similarly, when the medium-sized thirteenth part P13 is arranged in the sixth slot SL6 and the medium-sized fourteenth part P14 is arranged in the seventh slot SL7, the thirteenth part P13 is arranged in the seventh slot SL7. , arranging the fourteenth part P14 in the sixth slot SL6. Therefore, in the second embodiment, the simulation should be performed under a total of 4 conditions (2×2).

The simulation determines the arrangement of the 11th to 14th component types P11 to P14 in the 4th to 7th slots SL4 to SL7. In one example of the arithmetic processing result of FIG. 7, the 11th to 14th component types P11 to P14 are arranged in the 4th to 7th slots SL4 to SL7, respectively. As a result, the component types P11 to P15 to be supplied from the five automatic feeder devices ALS1, ALS2, ALM1, ALM2 and ALL are respectively determined.

As a result, the feeder arrangement table shown in FIG. 7 is completed. The control device displays the completed feeder layout table to the operator and instructs the work contents of the setup change work. In step S5, the operator performs setup change work according to the feeder arrangement table. The operator sets component supply reels R15, R11 to R14 corresponding to component types P15, P11 to P14 to the reel holding device 6, and sets the reel holding device 6 to each automatic feeder device ALL, ALS1, ALS2, ALM1, ALM2. mounted on the back of each.

When the changeover work is completed, in step S6, the control device produces the board K of the third board type B3. When the production of the predetermined number of substrates K is completed, the control device returns the execution of the arithmetic processing flow to step S3.

Steps S3, S4, and S5 are performed again prior to production of the next board K of the fourth board type B4. Even if the board K to be produced is changed from the third board type B3 to the fourth board type B4, the five automatic feeder apparatuses ALS1, ALS2, ALM1, ALM2, and ALL are fixed to the third to seventh slots SL3 to SL7. Not moved from position. Then, only the reel holding device 6 or the 11th to 15th component supply reels R11 to R15 are replaced in response to the change in component type arrangement.

According to this, when changing the type of components at the fixed position for each type, the automatic feeder device does not move and only the reel holding device 6 or the 11th to 15th component supply reels R11 to R15 are replaced. It can shorten the replacement work time. Also, the shortest mounting cycle time can be realized. Therefore, the production efficiency can be improved by comprehensively considering the changeover work time and the mounting cycle time.

In addition, since the five automatic feeder devices ALS1, ALS2, ALM1, ALM2 and ALL are normally used, the number of feeder devices 7 and 9 for replacement is reduced. This reduces equipment costs.

Further, the reel holding device 6 includes eleventh to fifteenth component supply reels R11 to R15, or a plurality of types of component supply reels R11 to R15, each of which is wound with a component storage tape used in the five automatic feeder devices ALS1, ALS2, ALM1, ALM2, and ALL. rotatably hold the component supply reels 81 and 82, and in the fixing setting step S1, five automatic feeder devices ALS1, ALS2, ALM1, ALM2 and ALL are set in a continuous range of a plurality of slots (3rd to 7th slots SL3 to SL7) are set to be arranged collectively.

According to this, the operator only needs to install reel holding devices 6 less than the five automatic feeder devices ALS1, ALS2, ALM1, ALM2, and ALL during setup change work. Therefore, setup change work is further reduced.
