Abstract
Description
[Technical Field]
[0001] The present invention relates to a technology for adsorbing components supplied to a component supply section by a nozzle by driving a component storage tape in a drive direction, the component storage tape storing components in each of a plurality of component storage sections arranged in a row. [Background technology]
[0002] In a component mounter that mounts components on a board, components supplied to a component supply unit are picked up by a nozzle and transferred to the board. A component supply device is used to supply components to the component supply unit. This component supply device supplies components stored on the component storage tape to the component supply unit in order by intermittently driving the component storage tape in a driving direction using a feed motor. In particular, the component supply device disclosed in Patent Document 1 is provided with two transport paths that can transport the component storage tape toward the component supply unit. Therefore, the feed motor drives the component storage tape transported along one of the two transport paths to supply components, and drives the component storage tape transported along the other transport path to supply components to the component supply unit. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] WO2017 / 187703 Summary of the Invention [Problem to be solved by the invention]
[0004] However, the force applied to the component storage tape when it is driven along the transport path can differ between the two transport paths. Therefore, the position of the component supplied to the component storage unit by the drive of the component storage tape by the feed motor can vary depending on the transport path of the component storage tape. Such fluctuations in the component supply position can cause the nozzle to fail to pick up the component.
[0005] The present invention has been made in consideration of the above-mentioned problems, and has an object to enable components stored on a component storage tape to be supplied to a component supply unit by a nozzle in a stable manner, regardless of the transport path used to transport the component storage tape, when the component storage tape is driven by a feed motor to supply the components stored on the component storage tape to the component supply unit. [Means for solving the problem]
[0006] A component supply device according to a first aspect of the present invention comprises a feed motor that drives a component storage tape that stores components in each of a plurality of component storage sections arranged in a row in a driving direction, thereby transporting the component storage tape toward a predetermined component supply section; a device main body having a first transport path and a second transport path as transport paths for transporting the component storage tape driven in the driving direction by the feed motor toward the component supply section; and a motor control unit that causes the feed motor to perform a component supply operation by driving the component storage tape in the driving direction by a transport amount in order to supply the components stored in each of the plurality of component storage sections to the component supply section in sequence.When the component storage tape driven by the feed motor is transported along the first transport path, the motor control unit sets the transport amount to a first transport amount and causes the feed motor to perform the component supply operation, while when the component storage tape driven by the feed motor is transported along the second transport path, the motor control unit sets the transport amount to a second transport amount different from the first transport amount and causes the feed motor to perform the component supply operation.
[0007] A component mounting machine according to a first aspect of the present invention comprises the above-mentioned component supply device, a board transport unit that supports a board, and a mounting unit that mounts the components supplied by the component supply device onto the board supported by the board transport unit.
[0008] A control method for a component supplying device according to a first aspect of the present invention is a control method for a component supplying device that includes a feed motor that drives a component storage tape that stores components in each of a plurality of component storage sections arranged in a row in a driving direction to transport the component storage tape toward a predetermined component supplying section, and an apparatus main body that has a first transport path and a second transport path as transport paths for transporting the component storage tape driven in the driving direction by the feed motor toward the component supplying section, the control method including the steps of: setting a transport amount for driving the component storage tape in the driving direction to supply the components stored in each of the plurality of component storage sections to the component supplying section in sequence; and driving the component storage tape by the transport amount using the feed motor; when the component storage tape driven by the feed motor is transported along the first transport path, the first transport amount is set as the transport amount; and when the component storage tape driven by the feed motor is transported along the second transport path, the second transport amount, which is different from the first transport amount, is set as the transport amount.
[0009] In the present invention (component supply device, component mounter, and component supply device control method) configured as described above, the component supply device is used to supply components to a plurality of component storage units arranged in a row using a component storage tape that stores components. The component supply device includes a feed motor that transports the component storage tape toward a predetermined component supply unit, and a device main body having a first transport path and a second transport path as transport paths along which the component storage tape driven in the drive direction by the feed motor is transported toward the component supply unit. Therefore, different forces are applied to the component storage tape when the component storage tape is transported along the first transport path and when the component storage tape is transported along the second transport path. To address this difference in forces depending on the transport path, the present invention sets the transport amount by which the component storage tape is driven in the drive direction to sequentially supply components stored in each of the plurality of component storage units to the component supply unit depending on the transport path. In other words, when the component storage tape driven by the feed motor is transported along the first transport path, the first transport amount is set as the transport amount, while when the component storage tape driven by the feed motor is transported along the second transport path, the second transport amount, which is different from the first transport amount, is set as the transport amount. This allows components to be supplied to a stable position regardless of the difference in the transport path between the first transport path and the second transport path. In this way, when the component storage tape is driven by the feed motor, components stored on the component storage tape are supplied to the component supply unit by the nozzles, and the nozzles can stably pick up components from the component supply unit regardless of the transport path used to transport the component storage tape.
[0010] The component supply device may further include a memory unit that stores a basic feed amount, a first offset amount, and a second offset amount different from the first offset amount, and the motor control unit calculates the first feed amount by adding the first offset amount to the basic feed amount, and calculates the second feed amount by adding the second offset amount to the basic feed amount. With this configuration, the first feed amount and the second feed amount can be appropriately set depending on the difference in force on the component storage tape between the first and second feed paths. This allows components to be supplied to a stable position regardless of the difference in the feed paths between the first and second feed paths.
[0011] The component supply device may also be configured such that the storage unit stores an offset table that associates the first offset amount and the second offset amount with the first transport path and the second transport path, respectively, and the motor control unit calculates the first transport amount by adding the first offset amount read from the offset table to the basic transport amount, and calculates the second transport amount by adding the second offset amount read from the offset table to the basic transport amount. With this configuration, the first transport amount and the second transport amount can be appropriately set depending on the difference in force on the component storage tape between the first transport path and the second transport path. This allows components to be supplied to a stable position regardless of the difference in the transport path between the first transport path and the second transport path.
[0012] The component supply device may further include a feed sprocket driven by the feed motor, a tape mounting unit that mounts a component storage tape at a predetermined temporary mounting position on the device body, a loading sprocket that engages with the component storage tape mounted at the temporary mounting position, and a loading motor that drives the loading sprocket, wherein the feed motor drives the feed sprocket to drive the component storage tape engaged with the feed sprocket in the drive direction, and the loading motor drives the loading sprocket to transport a leading end of the component storage tape mounted at the temporary mounting position to the feed sprocket and engage the leading end with the feed sprocket, the first transport path is a transport path along which the component storage tape mounted at the temporary mounting position is transported, and the second transport path is located below the first transport path and is a transport path along which the component storage tape that has been released from the temporary mounting position by the tape mounting unit and fallen from the first transport path is transported, and the motor control unit causes the loading motor to load the component storage tape mounted at the temporary mounting position before the component storage tape is released from the temporary mounting position. In this configuration, a large force is applied to the component storage tape transported along the first transport path because the tape mounting unit applies force to mount the component storage tape at the temporary mounting position. This results in a large difference in the force applied to the component storage tape between the first transport path and the second transport path. In contrast, by applying the present invention described above, components can be supplied to stable positions without relying on such a large difference in force.
[0013] The component supply device may further include a path determination unit that executes a path determination process to determine whether the used path, which is the path for feeding the component storage tape driven by the feed motor, is the first path or the second path, and if the path determination process determines that the first path is the used path, the motor control unit sets the first feed amount as the feed amount and causes the feed motor to perform the component supply operation, while if the path determination process determines that the second path is the used path, the motor control unit sets the second feed amount as the feed amount and causes the feed motor to perform the component supply operation. By setting the feed amount in accordance with the result of the path determination process in this way, it is possible to accurately set one of the first feed amount and the second feed amount according to the path along which the component storage tape is fed.
[0014] The component supply device may further include a first tape sensor provided for the first transport path, the first tape sensor outputting a detection signal when it detects a component storage tape located on the first transport path, and outputting a non-detection signal when it does not detect a component storage tape located on the first transport path, and the route determination unit determines that the first transport path is the used transport path while the first tape sensor continues to output the detection signal after loading is performed while the first tape sensor is outputting the detection signal, but determines that the second transport path is the used transport path when the output of the first tape sensor switches from the detection signal to the non-detection signal, and executes the route determination process. By executing the route determination process based on the output signal of the first tape sensor provided for the first transport path in this way, it is possible to accurately set one of the first transport amount and the second transport amount according to the route along which the component storage tape is transported.
[0015] The component supply device may further include a second tape sensor provided for the second transport path, the second tape sensor outputting a detection signal when it detects a component storage tape located on the second transport path, and a non-detection signal when it does not detect a component storage tape located on the second transport path, and the motor control unit determining that the second transport path is the used transport path when the second tape sensor outputs the detection signal, and determining that the first transport path is the used transport path when the second tape sensor outputs the non-detection signal. By performing the route determination process based on the output signal of the second tape sensor provided for the second transport path in this way, it is possible to accurately set one of the first transport amount and the second transport amount according to the route along which the component storage tape is transported.
[0016] The component supply device may also be configured such that the motor control unit executes an information acquisition process to acquire, from a control unit of a component mounter equipped with the component supply device, conveyance amount information indicating whether the first conveyance amount or the second conveyance amount should be set according to the used conveyance path, which is the conveyance path of the component storage tape driven by the feed motor, of the first conveyance path or the second conveyance path, and if the conveyance amount information indicates that the first conveyance amount should be set as the conveyance amount, the motor control unit sets the first conveyance amount to the conveyance amount and causes the feed motor to perform the component supply operation, while if the conveyance amount information indicates that the second conveyance amount should be set as the conveyance amount, the motor control unit sets the second conveyance amount to the conveyance amount and causes the feed motor to perform the component supply operation, and the control unit creates the conveyance amount information based on the number of component storage tapes attached to the component supply device and the execution history of loading by the component supply device. By setting the conveyance amount according to the acquired conveyance amount information in this way, it is possible to accurately set one of the first conveyance amount and the second conveyance amount according to the path along which the component storage tape is conveyed.
[0017] A component mounter according to a second aspect of the present invention comprises a component supply device having a feed motor that drives a component storage tape, which stores components in each of a plurality of component storage sections arranged in a row, in a driving direction to transport the component storage tape toward a predetermined component supply section; a mounting section that uses a nozzle to pick up components supplied to the component supply section; and a suction position control section that controls the position of the nozzle when picking up components supplied to the component supply section.The component supply device has a device main body that has a first transport path and a second transport path as transport paths for transporting the component storage tape, which is driven in the driving direction by the feed motor, toward the component supply section.When the component storage tape driven by the feed motor is transported along the first transport path, the suction position control section positions the nozzle at a first suction position and then allows the nozzle to pick up components supplied to the component supply section, while when the component storage tape driven by the feed motor is transported along the second transport path, the suction position control section positions the nozzle at a second suction position different from the first suction position and then allows the nozzle to pick up components supplied to the component supply section.
[0018] A component mounting method according to a second aspect of the present invention includes the steps of: supplying components to a component supply unit by a component supply device having a feed motor that drives a component storage tape, which stores components in each of a plurality of component storage units arranged in a row, in a driving direction to transport the component storage tape toward a predetermined component supply unit; and suctioning the components supplied to the component supply unit with the nozzle while controlling the position of the nozzle of the mounting unit. The component supply device has a device body that has a first transport path and a second transport path as transport paths for transporting the component storage tape driven in the driving direction by the feed motor toward the component supply unit. When the component storage tape driven by the feed motor is transported along the first transport path, the nozzle is positioned at a first suction position and then the components supplied to the component supply unit are suctioned by the nozzle. When the component storage tape driven by the feed motor is transported along the second transport path, the nozzle is positioned at a second suction position different from the first suction position and then the components supplied to the component supply unit are suctioned by the nozzle.
[0019] In the component mounter and component mounting method configured as described above, a component supply device is used to supply components to a plurality of component storage units arranged in a row using a component storage tape that stores components. The component supply device includes a feed motor that transports the component storage tape toward a predetermined component supply unit, and a device main body having a first transport path and a second transport path as transport paths along which the component storage tape, driven in a driving direction by the feed motor, is transported toward the component supply unit. Therefore, the force applied to the component storage tape when transported along the first transport path differs from that when transported along the second transport path, resulting in different component supply positions. To accommodate such differences in component supply positions, the present invention sets the position of the nozzle that picks up the components according to the transport path. That is, when the component storage tape driven by the feed motor is transported along the first transport path, the nozzle is positioned at a first pickup position. However, when the component storage tape driven by the feed motor is transported along the second transport path, the nozzle is positioned at a second pickup position different from the first pickup position. In this way, by driving the component storage tape with the feed motor, components stored on the component storage tape can be supplied to the component supply section by the nozzle in a stable manner, regardless of the transport path used to transport the component storage tape. [Effects of the Invention]
[0020] As described above, according to the present invention, when the component storage tape is driven by the feed motor to supply the components stored on the component storage tape to the component supply section, the components can be stably sucked from the component supply section by the nozzle, regardless of the transport path used to transport the component storage tape.

[0022] Fig. 1 is a plan view showing a schematic diagram of an example of a component mounter according to the present invention, and Fig. 2 is a block diagram showing the electrical configuration of the component mounter of Fig. 1. In Fig. 1, the horizontal X direction, the horizontal Y direction perpendicular to the X direction, and the vertical Z direction are appropriately shown. This component mounter 1 performs component mounting to mount component E (Fig. 3A) on board B.
[0023] 2, the component mounter 1 includes a main controller 100 that controls each unit of the component mounter 1. The main controller 100 includes an arithmetic processing unit 110 that executes calculations required for component mounting, and a storage unit 120 that stores programs and data used in component mounting. The arithmetic processing unit 110 is a processor such as a CPU (Central Processing Unit), and the storage unit 120 is a storage device such as an SSD (Solid State Drive).
[0024] The main controller 100 also has a drive control unit 130, a setup management unit 140, a UI control unit 150, and a communication unit 160. The drive control unit 130 controls the drive system of the component mounter 1. The setup management unit 140 manages the components E to be setup in the component mounter 1 based on the results of reading a reel ID 73 (FIG. 3B) attached to the component storage tape 8 by a reader 191 provided in the component mounter 1. The UI control unit 150 controls a UI (User Interface) 192 provided in the component mounter 1. The UI 192 has input devices such as a mouse and a keyboard, and an output device such as a display. Note that the input and output devices of the UI 192 do not need to be configured separately, and may be configured integrally using a touch panel display. The communication unit 160 also communicates with the tape feeder 3, which will be described later.
[0025] 1 includes a pair of conveyors 12, 12 provided on a base 11. The component mounter 1 mounts components E on a board B that has been carried in by the conveyor 12 from the upstream side in the X direction (board transport direction) to a work position 13 (the position of board B in FIG. 1) and then carries out the board B (component-mounted board B) on which component mounting has been completed from the work position 13 to the downstream side in the X direction by the conveyor 12.
[0026] The component mounter 1 is provided with a pair of Y-axis rails 21, 21 extending in the Y direction, a Y-axis ball screw 22 extending in the Y direction, and a Y-axis motor My that rotates and drives the Y-axis ball screw 22. An X-axis rail 24 extending in the X direction is supported by the pair of Y-axis rails 21, 21 so as to be movable in the Y direction, and is fixed to a nut of the Y-axis ball screw 22. An X-axis ball screw 25 extending in the X direction and an X-axis motor Mx that rotates and drives the X-axis ball screw 25 are attached to the X-axis rail 24. The component mounter 1 also includes a head unit 27 that is supported by the X-axis rails 24 so as to be movable in the X direction, and the head unit 27 is fixed to the nut of the X-axis ball screw 25. Therefore, the drive control unit 130 can rotate the Y-axis ball screw 22 using the Y-axis motor My to move the head unit 27 in the Y direction, and can rotate the X-axis ball screw 25 using the X-axis motor Mx to move the head unit 27 in the X direction.
[0027] Two component setup sections 28 are aligned in the X direction on each side of the pair of conveyors 12, 12 in the Y direction, and a feeder mounting carriage 281 is detachably attached to each component setup section 28. A plurality of tape feeders 3 aligned in the X direction are detachably attached to these feeder mounting carriages 281. Each tape feeder 3 has a component supply section Lf provided at its tip on the work position 13 side, and supplies components E to the component supply section Lf. A plurality of reel holders 282 aligned in the X direction are detachably attached to the feeder mounting carriage 281, and one tape feeder 3 and one reel holder 282 are aligned in the Y direction, corresponding to one another. A component supply reel 7 is detachably attached to each reel holder 282, and a component storage tape 8 (FIG. 3A), described later, is wound around this component supply reel 7. The tape feeder 3 then intermittently transports the component storage tape 8 unwound from the component supply reel 7 attached to the corresponding reel holder 282, thereby supplying the components E in the component storage tape 8 to the component supply section Lf.
[0028] The head unit 27 has a plurality of mounting heads 271 (four in the example of FIG. 1) arranged in the X direction, and a Z-axis motor Mz (FIG. 2) that raises and lowers the mounting heads 271 in the Z direction. The mounting heads 271 have an elongated shape extending in the Z direction, and can suck and hold components E using nozzles N that are detachably attached to the lower ends of the mounting heads 271. The mounting heads 271 then mount the components E on the board B by transferring the components E picked up from the component supply unit Lf using the nozzles N onto the board B.
[0029] Specifically, the drive control unit 130 drives the head unit 27 using the X-axis motor Mx and the Y-axis motor My to bring the nozzle N of the mounting head 271 face the component supply unit Lf from above. Next, the drive control unit 130 drives the Z-axis motor Mz to lower the mounting head 271 so that the nozzle N of the mounting head 271 abuts against the component E in the component supply unit Lf. The mounting head 271 generates negative pressure in the nozzle N that has come into contact with the component E, thereby adsorbing the component E to the nozzle N. When the drive control unit 130 raises the mounting head 271 using the Z-axis motor Mz, the component E adsorbed to the nozzle N is removed from the component supply unit Lf. Furthermore, the drive control unit 130 drives the head unit 27 using the X-axis motor Mx and the Y-axis motor My to bring the component E adsorbed to the nozzle N of the mounting head 271 face the mounting position of the board B at the work position 13 from above. Next, the drive control unit 130 causes the Z-axis motor Mz to lower the mounting head 271, so that the component E picked up by the nozzle N of the mounting head 271 comes into contact with the mounting position on the board B. Then, the mounting head 271 releases the negative pressure of the nozzle N that picks up the component E that has come into contact with the mounting position on the board B. In this way, the component E is transferred from the component supply unit Lf to the board B.
[0030] FIG. 3A is a perspective view schematically illustrating an example of a component storage tape held by a component supply reel. FIG. 3A illustrates the longitudinal direction Dl of the component storage tape 8 and the width direction Dw of the component storage tape 8. The longitudinal direction Dl and the width direction Dw are perpendicular to each other. The component storage tape 8 has a carrier tape 81 extending in the longitudinal direction Dl, and the carrier tape 81 has a peripheral edge portion 82, a pocket forming portion 83, and a peripheral edge portion 84. The peripheral edge portion 82, the pocket forming portion 83, and the peripheral edge portion 84 each extend in the longitudinal direction Dl. In the width direction Dw, the peripheral edge portion 82 is adjacent to the pocket forming portion 83, and the peripheral edge portion 84 is adjacent to the pocket forming portion 83 on the opposite side of the peripheral edge portion 82. In other words, in the width direction Dw, the pocket forming portion 83 is located between the peripheral edge portion 82 and the peripheral edge portion 84.
[0031] The pocket forming portion 83 of the carrier tape 81 has a plurality of pockets 85 arranged at a predetermined pocket pitch T85 in the longitudinal direction Dl. The carrier tape 81 has a tape surface 811 and a tape back surface 812 opposite to the tape surface 811, and each pocket 85 is open on the tape surface 811 and closed on the tape back surface 812. Each pocket 85 contains a small piece-like component E (electronic component), such as an integrated circuit, transistor, or capacitor.
[0032] A plurality of engagement holes 86 are arranged at equal intervals in the longitudinal direction Dl on the peripheral edge 84 of the carrier tape 81. Each engagement hole 86 penetrates between a tape front surface 811 and a tape back surface 812 of the carrier tape 81. The component storage tape 8 also has a cover tape 87 extending in the longitudinal direction Dl. The cover tape 87 is attached to the tape front surface 811 of the carrier tape 81 so as to overlap the pocket forming portion 83, thereby closing the opening of each pocket 85.
[0033] Fig. 3B is a diagram schematically illustrating an example of a component supply reel that holds a component storage tape. As shown in Fig. 3B, the component supply reel 7 has a disk-shaped central axis 71 and two side plates 72 that sandwich the central axis 71 from both sides, and the component storage tape 8 wound around the central axis 71 is supported from both sides by the side plates 72. The component storage tape 8 is wound so that the tape back surface 812 faces inward (in other words, toward the central axis 71) and the tape front surface 811 faces outward (in other words, the side opposite the central axis 71).
[0034] A reel ID 73 (e.g., a barcode) that identifies the components E stored in the component storage tape 8 wound around the component supply reel 7 is attached to the side plate 72 of the component supply reel 7. An operator who attaches the component storage tape 8 pulled out from the component supply reel 7 to a tape feeder 3 has the reader 191 read the reel ID 73 of the component supply reel 7 and the feeder ID attached to the tape feeder 3. In response to this, the setup management unit 140 registers the correspondence between the reel ID 73 and the feeder ID received from the reader 191, and manages the components E stored in the component storage tape 8 attached to each tape feeder 3 based on this correspondence.
[0035] As will be described later, two component storage tapes 8 can be attached to one tape feeder 3. Correspondingly, each reel holder 282 holds two component supply reels 7 aligned in the Y direction (FIG. 1). The tape feeder 3 then intermittently transports the component storage tape 8 pulled out from the component supply reel 7 in the corresponding reel holder 282 toward the head unit 27, thereby supplying the components E stored in the pockets 85 of the component storage tape 8 to the component supply section Lf (component supply operation).
[0036] FIG. 4 is a side view schematically illustrating an example of the configuration and operation of a tape feeder. In this figure and the following figures, the feed direction Df (parallel to the Y direction) in which the tape feeder 3 transports the component storage tape 8 is indicated as appropriate, and the arrow side of the feed direction Df is referred to as the "front side" of the feed direction Df, and the opposite side of the arrow of the feed direction Df is referred to as the "rear side" of the feed direction Df. To distinguish between the two component storage tapes 8 that can be attached to the tape feeder 3, different reference numerals 8A and 8B are used for the component storage tapes 8 in this figure and the following figures. Note that the configuration of the tape feeder 3 (e.g., the transport path of the component storage tape 8) is depicted only schematically in this figure.
[0037] The tape feeder 3 includes a feeder body 31, a feed motor Mf provided at the front end of the feeder body 31 in the feed direction Df, and a loading motor Ml provided at the rear end of the feeder body 31. The feeder body 31 has a flat case 32 that is thin in the X direction and long in the feed direction Df. A tape insertion opening 33 (shown by a broken line) extending in the Z direction opens at the rear end of the case 32 in the feed direction Df, and the component supply unit Lf described above is provided on the top surface of the front end of the case 32 in the feed direction Df. A tape insertion path 34 extending from the tape insertion opening 33 to the component supply unit Lf is provided within the feeder body 31. The feeder body 31 supplies components E to the component supply unit Lf by transporting the component storage tape 8 inserted into the tape insertion path 34 from the tape insertion opening 33 in the feed direction Df using the driving forces of the feed motor Mf and the loading motor Ml.
[0038] The tape feeder 3 also includes, in the case 32 of the feeder main body 31, a loading sprocket 35 disposed adjacent to the tape insertion opening 33 and a gear 36 that transmits the driving force of the loading motor Ml to the loading sprocket 35. The loading sprocket 35 rotates due to the driving force generated by the loading motor Ml. The tape feeder 3 also includes a tape setting unit 41 that is detachably attached to the case 32 of the feeder main body 31. The tape setting unit 41 attached to the case 32 faces the loading sprocket 35 from below, and sandwiches the component storage tape 8 between the tape setting unit 41 and the loading sprocket 35, thereby engaging the engagement hole 86 of the component storage tape 8 with the loading sprocket 35. In other words, a tape setting position Ls is provided between the tape setting unit 41 attached to the case 32 and the loading sprocket 35. The component storage tape 8 can be engaged with the loading sprocket 35 by attaching the component storage tape 8 to the tape setting position Ls using the tape setting unit 41. Therefore, when the loading sprocket 35 rotates, the component storage tape 8 attached to the tape set position Ls is transported in the feed direction Df. The component storage tape 8 is attached to the tape set position Ls so that the tape front surface 811 faces upward and the tape back surface 812 faces downward. As a result, the component storage tape 8 is transported in the feed direction Df with the openings of the pockets 85 of the component storage tape 8 facing upward.
[0039] Furthermore, the tape feeder 3 includes a feed sprocket 37 located at its front end and a gear 38 that transmits the driving force of the feed motor Mf to the feed sprocket 37, both of which are housed within the case 32 of the feeder body 31. The feed sprocket 37 rotates due to the driving force generated by the feed motor Mf. An engagement position Le, which corresponds to the upper end of the feed sprocket 37, is located between the tape set position Ls and the component supply unit Lf. The tape insertion path 34 is provided with a loading path 341 that extends from the tape set position Ls to the engagement position Le. The component storage tape 8, which is transported in the feed direction Df by the loading sprocket 35, moves along the loading path 341 from the tape set position Ls to the engagement position Le. When the component storage tape 8 reaches the engagement position Le, the engagement hole 86 engages with the feed sprocket 37. As a result, when the feed sprocket 37 rotates intermittently, the component storage tape 8 is intermittently transported in the feed direction Df, and components E are supplied to the component supply unit Lf.
[0040] The feeder body 31 also has a cutter that contacts the component storage tape 8 upstream of the component supply unit Lf in the feed direction Df. This cutter cuts the cover tape 87 of the component storage tape 8, which is intermittently transported in the feed direction Df, in the center and rolls it up on both sides, thereby exposing the components E supplied to the component supply unit Lf. The configuration for exposing the components in this manner is similar to that described, for example, in JP 2015-053320 A. However, the configuration for exposing the components E is not limited to this example, and the components E may also be exposed by peeling off the cover tape 87 from the carrier tape 81.
[0041] The loading path 341 includes a junction J between the tape setting position Ls and the engagement position Le, an upper introduction path Pu from the tape setting position Ls to the junction J, and a supply path Ps from the junction J to the engagement position Le. The tape insertion path 34 also includes a lower introduction path Pl located below the upper introduction path Pu. The lower introduction path Pl extends from the tape insertion opening 33 to the junction J and merges with the supply path Ps of the loading path 341 at the junction J. When the tape setting unit 41 is removed from the case 32, the component storage tape 8 held at the tape setting position Ls falls from the upper introduction path Pu to the lower introduction path Pl. The component storage tape 8 is driven in the feed direction Df by the feed sprocket 37 to merge with the supply path Ps from the lower introduction path Pl at the junction J and then reaches the engagement position Le.
[0042] Step S11 corresponds to a state in which the tape feeder 3 is being used for component mounting by the mounting head 271. That is, the component storage tape 8A (leading tape) is inserted into the feeder main body 31 along the lower introduction path Pl and the supply path Ps, and the feed motor Mf intermittently transports the component storage tape 8A engaged with the feed sprocket 37 in the feed direction Df, thereby supplying the components E to be mounted on the board B to the component supply unit Lf. That is, the feed motor Mf intermittently drives the component storage tape 8A provided along the lower introduction path Pl in the feed direction Df by a predetermined transport amount, thereby supplying the multiple components E stored on the component storage tape 8A in sequence to the component supply unit Lf.
[0043] In step S11, the leading end of the component storage tape 8B (subsequent tape) to be used for mounting components after the component storage tape 8A is attached to the tape set position Ls between the loading sprocket 35 and the tape set unit 41. In this way, the component storage tape 8B to be used next waits at the tape set position Ls at the rear end of the feeder body 31.
[0044] As shown in step S12, when the components E in the component storage tape 8A are used up and the tape feeder 3 discharges the component storage tape 8A from its front end in the feed direction Df, loading is performed as shown in step S13. Specifically, the loading sprocket 35 starts to rotate and feeds the component storage tape 8B in the feed direction Df toward the engagement position Le, causing the front end of the component storage tape 8B to engage with the feed sprocket 37. When this loading is completed (step S13), the component storage tape 8B (the following tape) is inserted into the feeder main body 31 along the upper introduction path Pu and the supply path Ps, and the feed motor Mf intermittently transports the component storage tape 8B engaged with the feed sprocket 37 in the feed direction Df, thereby supplying the components E to be mounted on the board B to the component supply unit Lf. In other words, the feed motor Mf intermittently drives the component storage tape 8B arranged along the upper introduction path Pu in the feed direction Df by a predetermined conveying amount, thereby supplying multiple components E stored on the component storage tape 8B in sequence to the component supply section Lf.
[0045] Furthermore, in step S14, when the operator removes the tape setting unit 41 from the case 32, the component storage tape 8B comes off the loading sprocket 35 and falls into the lower introduction path Pl. This allows the feed sprocket 37 to intermittently transport the component storage tape 8B provided along the lower introduction path Pl in the feed direction Df, thereby supplying the components E in the component storage tape 8B to the component supply unit Lf. Incidentally, after step S14, the operator can attach the component storage tape 8 to be used for component mounting after the component storage tape 8B to the tape setting position Ls between the loading sprocket 35 and the tape setting unit 41, and have it wait there.
[0046] A tape sensor Sa is disposed along the lower introduction path Pl. FIGS. 5A and 5B show an example of a tape sensor disposed along the lower introduction path Pl. The tape sensor Sa includes a sensor dog 431 and a photosensor 432. The sensor dog 431 is supported within the case 32 so as to be rotatable about a rotation axis parallel to the X direction. The photosensor 432 includes a light-emitting element and a light-receiving element that face each other and are spaced apart in the X direction. The light-emitting element emits light toward the light-receiving element, and the light-receiving element outputs a signal corresponding to the amount of detected light. When the component storage tape 8 is not present along the lower introduction path Pl (FIG. 5A), the sensor dog 431 protrudes into the lower introduction path Pl due to the biasing force of an elastic member such as a spring, and retreats from between the light-emitting element and the light-receiving element of the photosensor 432. As a result, the light emitted from the light-emitting element reaches the light-receiving element. On the other hand, when the component storage tape 8 is present on the lower introduction path Pl (FIG. 5B), the sensor dog 431 is pressed by the component storage tape 8 and positioned between the light-emitting element and the light-receiving element of the photosensor 432. As a result, the light emitted from the light-emitting element is blocked by the sensor dog 431 and does not reach the light-receiving element. In this way, the tape sensor Sa outputs a signal from the light-receiving element according to the presence or absence of the component storage tape 8 on the lower introduction path Pl. In other words, the tape sensor Sa outputs an ON signal when it detects the component storage tape 8 on the lower introduction path Pl, and outputs an OFF signal when it does not detect the component storage tape 8 on the lower introduction path Pl.
[0047] Furthermore, as shown in FIG. 2, the tape feeder 3 has a feeder controller 300 that controls the operation of the tape feeder 3. The feeder controller 300 has an arithmetic processing unit 310, a communication unit 320, a motor control unit 330, a path determination unit 340, and a memory unit 350. The arithmetic processing unit 310 performs calculations required to control the operation of the tape feeder 3. The communication unit 320 communicates with the communication unit 160 of the main controller 100. The motor control unit 330 controls the feed motor Mf and the loading motor Ml to cause the feed motor Mf and the loading motor Ml to perform the operations described with reference to FIG. 4, for example. The path determination unit 340 determines the path (used conveying path) along which the component storage tape 8 currently being used to supply components E to the component supply unit Lf is conveyed. Specifically, the path determination unit 340 determines whether the path (used conveying path) along which the component storage tape 8, which is intermittently driven in the feed direction Df by the feed motor Mf, is conveyed is the upper introduction path Pu or the lower introduction path Pl, based on the detection result of the tape sensor Sa. That is, when the tape sensor Sa detects the component storage tape 8 on the lower introduction path Pl and outputs an ON signal, the path determination unit 340 determines that the lower introduction path Pl is the used conveying path. On the other hand, when the tape sensor Sa does not detect the component storage tape 8 on the lower introduction path Pl and outputs an OFF signal, the path determination unit 340 determines that the upper introduction path Pu is the used conveying path. The memory unit 350 is a storage device such as an SSD, and stores data used for supplying components E by the tape feeder 3.
[0048] Fig. 6 is a flowchart showing a first example of control executed for the feeding of the component storage tape by the tape feeder, and Fig. 7 is a diagram showing an example of an offset table OT used in the control of Fig. 6. The offset table OT of Fig. 7 indicates an offset amount for the feed distance by which the feed motor Mf feeds the component storage tape 8 in the feed direction in order to supply components E to the component supply unit Lf, and is stored in advance in the storage unit 350. The reason for using such an offset amount is as follows.
[0049] As described above, the supply of components E to the component supply unit Lf is performed by the feed motor Mf intermittently driving the component storage tape 8 in the feed direction Df. Ideally, this component supply can be performed by driving the component storage tape 8 in the feed direction Df by a pocket pitch T85 (e.g., 4 mm) at which the pockets 85 that store the components E are arranged. However, due to various causes (e.g., frictional force acting on the component storage tape 8, etc.), even if the feed motor Mf drives the component storage tape 8 by the pocket pitch T85, the movement distance of the components E stored in the pockets 85 may not be full the pocket pitch T85.
[0050] For example, when the component storage tape 8 transported along the upper introduction path Pu is driven by the feed motor Mf, a force for clamping the component storage tape 8 between the tape set unit 41 and the loading sprocket 35 acts on the component storage tape 8. Therefore, the component storage tape 8 is transported in the feed direction Df while elastically stretching in the feed direction Df due to this clamping force and the driving force of the feed motor Mf. Then, when the intermittent driving by the feed motor Mf ends and the driving force of the feed motor Mf disappears, the component storage tape 8 elastically contracts. As a result, the components E supplied to the component supply unit Lf are displaced upstream in the feed direction Df (i.e., returned).
[0051] To correct for this displacement, the feed amount of the component storage tape 8 driven by the feed motor Mf for supplying components E to the component supply unit Lf is set to the pocket pitch T85 plus an offset amount. In particular, taking into consideration the difference in the amount of displacement of components E between the upper introduction path Pu and the lower introduction path Pl, different offset amounts are associated with the upper introduction path Pu and the lower introduction path Pl. That is, as shown in the offset table OT in FIG. 7, the lower introduction path Pl is associated with lower offset amounts Fl (Fl1 to Fl5), and the upper introduction path Pu is associated with upper offset amounts Fu (Fu1 to Fu5).
[0052] Furthermore, the upper offset amount Fu is greater than the lower offset amount Fl. For example, the upper offset amount Fu is approximately 0.05 mm to 0.1 mm greater than the lower offset amount Fl. This is because the force for clamping the component storage tape 8 between the tape set unit 41 and the loading sprocket 35 acts on the component storage tape 8 in the upper introduction path Pu but does not act on the component storage tape 8 in the lower introduction path Pl. Note that the feeder type in the offset table OT in FIG. 7 indicates the type of tape feeder 3 according to the size (SS, S, M, L, LL) of the components supplied by the tape feeder 3.
[0053] Based on the above, the explanation of the flowchart in Fig. 6 will be continued. In step S101, the calculation processing unit 310 determines whether the communication unit 320 has received a supply command from the communication unit 160 of the main controller 100 to instruct the supply of the component E to the component supply unit Lf. If it is determined that the supply command has been received ("YES" in step S101), the route determination unit 340 determines which of the upper introduction route Pu and the lower introduction route Pl is the used conveyance route (step S102, route determination process). Specifically, the route determination unit 340 determines the used conveyance route based on the output (ON signal / OFF signal) of the tape sensor Sa described above.
[0054] When the lower introduction path Pl is the used conveying path (when "path Pl" is selected in step S102), the motor control unit 330 sets the lower offset amount Fl as the offset amount used to calculate the conveying amount (step S103). Specifically, the motor control unit 330 reads out the lower offset amount Fl corresponding to the feeder type of the tape feeder 3 to which the motor control unit 330 belongs from the offset table OT, and sets it as the offset amount used to calculate the conveying amount. On the other hand, when the upper introduction path Pu is the used conveying path (when "path Pu" is selected in step S102), the motor control unit 330 sets the upper offset amount Fu as the offset amount used to calculate the conveying amount (step S104). Specifically, the motor control unit 330 reads out the upper offset amount Fu corresponding to the feeder type of the tape feeder 3 to which the motor control unit 330 belongs from the offset table OT, and sets it as the offset amount used to calculate the conveying amount.
[0055] In step S105, the motor control unit 330 sets the transport amount based on the offset amount set in step S103 or step S104 based on the result of step S102. Specifically, the motor control unit 330 sets the transport amount by adding the set offset amount, either the lower offset amount Fl or the upper offset amount Fu, to the pocket pitch T85.
[0056] Then, the motor control unit 330 transmits a drive signal (pulse signal) to the feed motor Mf to feed the component storage tape 8 by the feed distance set in step S105. As a result, the feed motor Mf rotates by an angle corresponding to the feed distance, and feeds the component storage tape 8 in the feed direction Df by the feed distance (step S106). When the feeding of the component storage tape 8 is completed in this manner, the communication unit 320 transmits a signal indicating the completion of feeding to the communication unit 160 of the main controller 100.
[0057] In a first example of tape conveyance control shown in Fig. 6, a tape feeder 3 (component supply device) is used to supply components E by a component storage tape 8 that stores components E in each of a plurality of pockets 85 (component storage sections) arranged in a row. The tape feeder 3 includes a feed motor Mf that conveys the component storage tape 8 toward a predetermined component supply section Lf, and a feeder main body 31 (device main body) having an upper introduction path Pu (first conveyance path) and a lower introduction path Pl (second conveyance path) as conveyance paths along which the component storage tape 8 driven by the feed motor Mf in a feed direction Df (drive direction) is conveyed toward the component supply section Lf. Therefore, the force applied to the component storage tape 8 when driving the component storage tape 8 conveyed along the upper introduction path Pu differs from the force applied to the component storage tape 8 when driving the component storage tape 8 conveyed along the lower introduction path Pl. To accommodate such differences in force depending on the conveying path, in this embodiment, the conveyance distance for driving the component storage tape 8 in the feed direction Df to sequentially supply the components E stored in each of the multiple pockets 85 to the component supply unit Lf is set depending on the conveying path. That is, when the component storage tape 8 driven by the feed motor Mf is conveyed along the upper introduction path Pu, a first conveyance distance (= T85 + Fu) is set, which is the pocket pitch T85 plus an upper offset amount Fu. On the other hand, when the component storage tape 8 driven by the feed motor Mf is conveyed along the lower introduction path Pl, a second conveyance distance (= T85 + Fl) different from the first conveyance distance is set, which is the pocket pitch T85 plus a lower offset amount Fl. This allows the components E to be supplied to a stable position regardless of the difference in the conveying path between the upper introduction path Pu and the lower introduction path Pl. In this way, by driving the component storage tape 8 by the feed motor Mf, the components E stored on the component storage tape 8 can be supplied to the component supply section Lf by the nozzle N in a stable manner, regardless of the transport path used to transport the component storage tape 8.
[0058] Here, the stabilization of the supply position of the component E will be explained using FIG. 8 . FIG. 8 is a diagram schematically illustrating an example of the supply position of the component when the same offset amount is set for the upper introduction path and the lower introduction path, and when different offset amounts are set. When the same offset amount is set for the upper introduction path Pu and the lower introduction path Pl, in other words, when the same transport distance is set, a deviation amount Δ occurs in the position where the component E is supplied. In contrast, when different offset amounts are set for the upper introduction path Pu and the lower introduction path Pl, in other words, when different transport distances are set, as in the above embodiment, no deviation amount Δ occurs in the position where the component E is supplied. In this way, it is possible to stabilize the position of the component E supplied to the component supply unit Lf.
[0059] The tape feeder 3 is also provided with a memory unit 350 that stores a pocket pitch T85 (basic feed amount), an upper offset amount Fu (first offset amount), and a lower offset amount Fl (second offset amount) that is different from the upper offset amount Fu. The motor control unit 330 calculates the first feed amount (= T85 + Fu) by adding the upper offset amount Fu to the pocket pitch T85, and calculates the second feed amount (= T85 + Fl) by adding the lower offset amount Fl to the pocket pitch T85. With this configuration, the first feed amount (= T85 + Fu) and the second feed amount (= T85 + Fl) can be appropriately set depending on the difference in force on the component storage tape 8 between the upper offset amount Fu and the lower offset amount Fl. This allows components E to be supplied to a stable position regardless of the difference in the feed path between the upper introduction path Pu and the lower introduction path Pl.
[0060] The storage unit 350 also stores an offset table OT that associates the upper offset amount Fu and the lower offset amount Fl with the upper introduction path Pu and the lower introduction path Pl, respectively. The motor control unit 330 calculates the first conveyance amount (= T85 + Fu) by adding the upper offset amount Fu read from the offset table OT to the pocket pitch T85, and calculates the second conveyance amount (T85 + Fl) by adding the lower offset amount Fl read from the offset table OT to the pocket pitch T85. This configuration allows the first conveyance amount (= T85 + Fu) and the second conveyance amount (T85 + Fl) to be appropriately set depending on the difference in force on the component storage tape 8 between the upper introduction path Pu and the lower introduction path Pl. This allows the component E to be supplied to a stable position regardless of the difference in the conveyance path between the upper introduction path Pu and the lower introduction path Pl.
[0061] The tape feeder 3 also includes a feed sprocket 37 driven by a feed motor Mf, a tape setting unit 41 that sets the component storage tape 8 at a predetermined tape setting position Ls (temporary setting position) of the feeder main body 31 (device main body), a loading sprocket 35 that engages with the component storage tape 8 set at the tape setting position Ls, and a loading motor Ml that drives the loading sprocket 35. The feed motor Mf drives the feed sprocket 37 to drive the component storage tape 8 engaged with the feed sprocket 37 in the feed direction Df. The loading motor Ml drives the loading sprocket 35 to transport the leading end of the component storage tape 8 set at the tape setting position Ls to the feed sprocket 37 and load the leading end into the feed sprocket 37. The upper offset amount Fu is a transport path along which the component storage tape 8 attached to the tape set position Ls is transported. The lower offset amount Fl is provided below the upper offset amount Fu and is a transport path along which the component storage tape 8 that has fallen from the upper offset amount Fu after being released from the tape set position Ls by the tape set unit 41 is transported. The motor control unit 330 controls the loading motor M1 to load the component storage tape 8 attached to the tape set position Ls before the tape set unit 41 releases the component storage tape 8 from the tape set position Ls. In this configuration, a force for attaching the component storage tape 8 to the tape set position Ls by the tape set unit 41 acts on the component storage tape 8 transported along the upper offset amount Fu, resulting in a large force being applied to the component storage tape 8 transported along the upper offset amount Fu. Therefore, a large difference occurs in the force applied to the component storage tape 8 between the upper offset amount Fu and the lower offset amount Fl. By applying the above-described control, components E can be supplied to a stable position without being affected by such a large force difference.
[0062] The tape feeder 3 is also provided with a path determination unit 340 that executes a path determination process (step S102) to determine whether the used conveyance path, which is the conveyance path of the component storage tape 8 driven by the feed motor Mf, is the upper offset amount Fu or the lower offset amount Fl. If the path determination process (step S102) determines that the used conveyance path is the upper offset amount Fu, the motor control unit 330 sets the first conveyance amount (= T85 + Fu) as the conveyance amount and causes the feed motor to perform the component supply operation (steps S104, S105, S106). On the other hand, if the path determination process (step S102) determines that the used conveyance path is the lower offset amount Fl, the motor control unit 330 sets the second conveyance amount (= T85 + Fl) as the conveyance amount and causes the feed motor Mf to perform the component supply operation (steps S103, S105, S106). By setting the conveying amount in accordance with the results of the path determination process (step S102) in this manner, it is possible to accurately set one of the first conveying amount (= T85 + Fu) and the second conveying amount (= T85 + Fl) according to the path along which the component storage tape 8 is conveyed.
[0063] The tape feeder 3 is also provided with a tape sensor Sa (second tape sensor) provided for the lower introduction path Pl. The tape sensor Sa outputs an ON signal (detection signal) when it detects the component storage tape 8 located on the lower introduction path Pl, and outputs an OFF signal (non-detection signal) when it does not detect the component storage tape 8 located on the lower introduction path Pl. The motor control unit 330 determines that the lower introduction path Pl is the used conveyance path when the tape sensor Sa outputs an ON signal, and determines that the upper offset amount Fu is the used conveyance path when the tape sensor Sa outputs an OFF signal (step S102). By performing the path determination process (step S102) based on the output signal of the tape sensor Sa provided for the lower offset amount Fl in this way, it is possible to accurately set one of the first conveyance amount (= T85 + Fu) and the second conveyance amount (= T85 + Fl) according to the path along which the component storage tape 8 is conveyed.
[0064] In the above embodiment, the tape sensor Sa is used to determine the used conveyance route. However, it is also possible to determine the used conveyance route without using such a tape sensor Sa. Specifically, the used conveyance route can be determined based on the number of component storage tapes 8 attached to the target tape feeder 3, in other words, the number of component supply reels 7 registered by the setup management unit 140 as the reel holders 282 corresponding to the tape feeder 3.
[0065] 9A, 9B, and 9C are diagrams showing an example of the transition of component supply reels registered in correspondence with tape feeders. As described above, when the component storage tape 8 pulled out from the component supply reel 7 is loaded into the tape feeder 3, the reel ID 73 of the component supply reel 7 is acquired by the reader 191 and registered in the setup management unit 140 as the reel ID 73 corresponding to the tape feeder 3.
[0066] 9A to 9C, the feeder set position indicates the position where the tape feeder 3 is set. The feeder ID is an identifier provided on the tape feeder 3 to identify the tape feeder 3. The example of FIGS. 9A to 9C shows the transition of the component supply reel 7 registered in correspondence with the tape feeder 3 set at feeder set position F33 and having a feeder ID of FD125. The first reel ID and second reel ID are each the reel ID 73 of the component supply reel 7 registered for the tape feeder 3. Note that first and second indicate the order of registration, with the first reel ID being registered before the second reel ID.
[0067] In the state shown in Fig. 9A, a component supply reel 7 with a reel ID of RD5 and a component supply reel 7 with a reel ID of RD2 are registered with the tape feeder 3. The component supply reel 7 with a reel ID of RD5 is attached to the tape feeder 3 before the component supply reel 7 with a reel ID of RD2. Therefore, the component storage tape 8 unwound from the component supply reel 7 with a reel ID of RD5 is transported along the lower introduction path Pl and is transported by the feed motor Mf toward the component supply unit Lf. Meanwhile, the leading end of the component storage tape 8 unwound from the component supply reel 7 with a reel ID of RD2 waits at the tape set position Ls.
[0068] When component E on the component storage tape 8 unwound from the component supply reel 7 with reel ID RD5 in the state shown in Figure 9A is used up, the component supply reel 7 with reel ID RD5 is deleted from the registration (Figure 9B). Furthermore, loading is performed on the component storage tape 8 unwound from the component supply reel 7 with reel ID RD2, and RD2 is promoted to the first reel ID.
[0069] From the state shown in Figure 9B, when the leading end of the component storage tape 8 pulled out from the component supply reel 7 with the reel ID RD8 is attached to the tape set position Ls, the RD8 is acquired by the reader 191 and newly registered (Figure 9C).
[0070] 9A to 9C, the flowchart of Fig. 10 will be described. Fig. 10 is a flowchart showing a second example of control executed for the transport of the component storage tape by the tape feeder. Note that in the flowchart of Fig. 10, the path of the component storage tape 8 is not determined based on the tape sensor Sa, and therefore the tape sensor Sa and the path determination unit 340 are not provided.
[0071] In step S201, the arithmetic processing unit 110 of the main controller 100 checks whether the type of tape feeder 3 to be controlled in Fig. 10 is an automatic loading type (Fig. 4) that can simultaneously load two component storage tapes 8 and automatically loads the component storage tapes 8. In other words, there are types of tape feeders used in the component mounter 1 that are different from the automatic loading type that loads only one component storage tape 8. Then, if the type of the target tape feeder 3 is an automatic loading type (if "YES" in step S201), steps S202 to S207 are executed.
[0072] In step S202, the calculation processing unit 110 determines whether the number of component supply reels 7 registered by the setup management unit 140 in correspondence with the target tape feeder 3 is 0. If the number of registered component supply reels 7 is 0 (if "YES" in step S202), the process returns to step S201. On the other hand, if the number of registered component supply reels 7 is not 0 (if "NO" in step S202), the calculation processing unit 110 determines whether the number of component supply reels 7 registered by the setup management unit 140 in correspondence with the target tape feeder 3 is 2.
[0073] If the number of registered component supply reels 7 is two ("YES" in step S203), the state is as shown in FIG. 9A or 9C. That is, components E on the component storage tape 8, which is pulled out from the component storage tape 8 whose reel ID 73 is the first reel ID and transported along the lower introduction path Pl, are supplied to the component supply unit Lf by the feed motor Mf. Therefore, the calculation processing unit 110 sets the lower offset amount Fl as the offset amount used to calculate the transport amount (step S204). Specifically, the calculation processing unit 110 transmits an offset setting command requesting the setting of the lower offset amount Fl to the communication unit 320 of the tape feeder 3 via the communication unit 160, and the motor control unit 330 sets the lower offset amount Fl in accordance with the offset setting command received by the communication unit 320. As a result, the component storage tape 8 is transported by the feed motor Mf at the transport amount calculated based on the lower offset amount Fl.
[0074] If the number of registered component supply reels 7 is not two ("NO" in step S203), the components E stored on the component storage tape 8 of the previously registered component supply reel 7 will be used up, and the leading end of the component storage tape 8 pulled out from the later registered component supply reel 7 will wait at the tape set position Ls (FIG. 9B). Therefore, the calculation processing unit 110 waits for the loading of the component storage tape 8 waiting at the tape set position Ls to be completed (step S205).
[0075] When the loading is completed, the UI control unit 150 displays on the display of the UI 192 that presetting is possible (step S206). Here, presetting refers to the operation of removing the tape setting unit 41 from the tape setting position Ls, dropping the preceding component storage tape 8 from the upper introduction path Pu to the lower introduction path Pl, and loading the succeeding component storage tape 8 at the tape setting position Ls.
[0076] 9B. That is, the component E on the component storage tape 8, whose reel ID 73 is the first reel ID, is pulled out and transported along the upper introduction path Pu. The component E is then supplied to the component supply unit Lf by the feed motor Mf. Therefore, the calculation processing unit 110 sets the upper offset amount Fu as the offset amount used to calculate the transport amount (step S207). Specifically, the calculation processing unit 110 transmits an offset setting command requesting the setting of the upper offset amount Fu to the communication unit 320 of the tape feeder 3 via the communication unit 160. The motor control unit 330 sets the upper offset amount Fu in accordance with the offset setting command received by the communication unit 320. As a result, the component storage tape 8 is transported by the feed motor Mf at the transport amount calculated based on the upper offset amount Fu.
[0077] 10 , when the component storage tape 8 driven by the feed motor Mf is fed along the upper introduction path Pu, a first feed amount (= T85 + Fu) is set, which is the pocket pitch T85 plus the upper offset amount Fu. Meanwhile, when the component storage tape 8 driven by the feed motor Mf is fed along the lower introduction path Pl, a second feed amount (= T85 + Fl) different from the first feed amount is set, which is the pocket pitch T85 plus the lower offset amount Fl. This allows components E to be supplied to a stable position regardless of the difference in the feed path between the upper introduction path Pu and the lower introduction path Pl. In this way, when the component storage tape 8 is driven by the feed motor Mf to supply the components E stored on the component storage tape 8 to the component supply unit Lf, the nozzle N can stably pick up the components E from the component supply unit Lf regardless of the feed path used to feed the component storage tape 8.
[0078] The motor control unit 330 also acquires from the main controller 100 (control unit) an offset setting command (conveyance amount information) indicating the conveyance amount to be set according to the conveyance path to be used, which is the conveyance path of the component storage tape 8 driven by the feed motor Mf, of either the upper introduction path Pu or the lower introduction path Pl (information acquisition process). When the offset setting command indicates that the first conveyance amount (=T85+Fu) should be set (step S207), the motor control unit 330 sets the conveyance amount to the first conveyance amount (=T85+Fu) and causes the feed motor Mf to perform a component supply operation to supply components E to the component supply unit Lf by conveying the component storage tape 8 in the feed direction Df by the set conveyance amount. On the other hand, if the offset setting command indicates that the second feed amount (= T85 + Fl) should be set (step S204), the motor control unit 330 sets the feed amount to the second feed amount (= T85 + Fl) and controls the feed motor Mf to perform a component supply operation in which the component storage tape 8 is fed in the feed direction Df at the second feed amount to supply components E to the component supply unit Lf. In response to this, the main controller 100 generates an offset setting command (steps S204 and S207) based on the number of component storage tapes 8 attached to the tape feeder 3 (steps S202 and S203) and the loading execution history of the tape feeder 3 (step S205). By setting the feed amount according to the result of acquiring the offset setting command in this way, it is possible to accurately set either the first feed amount (= T85 + Fu) or the second feed amount (= T85 + Fl) depending on the path along which the component storage tape 8 is fed.
[0079] Fig. 11 is a diagram showing the configuration and operation of a modified tape feeder, Fig. 12 is a block diagram showing the electrical configuration of the tape feeder of Fig. 11, and Fig. 13 is a diagram illustrating control executed by the tape feeder of Fig. 11. The difference between the tape feeder 3 shown in Figs. 11 to 13 and the tape feeder 3 shown in Figs. 2 and 4 is the number and positions of sensors that detect the component storage tape 8. In other words, the tape feeder 3 shown in Figs. 11 to 13 does not have tape sensor Sa, but has tape sensors Sb1, Sb2, and Sb3.
[0080] The tape sensor Sb1 is provided on the supply path Ps and detects the presence or absence of the component storage tape 8 on the supply path Ps. When the tape sensor Sb1 detects the component storage tape 8 on the supply path Ps, it outputs an ON signal to the path determination unit 340, and when it does not detect the component storage tape 8 on the supply path Ps, it outputs an OFF signal to the path determination unit 340.
[0081] The tape sensor Sb2 is provided at the junction J and detects the presence or absence of the component storage tape 8 at the junction J. When the tape sensor Sb2 detects the component storage tape 8 located at the junction J, it outputs an ON signal to the route determination unit 340, and when it does not detect the component storage tape 8 located at the junction J, it outputs an OFF signal to the route determination unit 340.
[0082] The tape sensor Sb3 is provided for the upper introduction path Pu and detects the presence or absence of the component storage tape 8 on the upper introduction path Pu. When the tape sensor Sb3 detects the component storage tape 8 located on the upper introduction path Pu, it outputs an ON signal to the path determination unit 340, and when it does not detect the component storage tape 8 located on the upper introduction path Pu, it outputs an OFF signal to the path determination unit 340.
[0083] The detection states (sensor detection states) of the component storage tape 8 by these three tape sensors Sb1 to Sb3 include detection state 1 to detection state 6 shown in Fig. 13. The path determination unit 340 can make the following determination for each of detection state 1 to detection state 6.
[0084] In detection state 1, in which tape sensor Sb1 outputs an OFF signal, tape sensor Sb2 outputs an OFF signal, and tape sensor Sb3 outputs an OFF signal, it can be determined that there is no component storage tape 8 attached to tape feeder 3.
[0085] In detection state 2, in which tape sensor Sb1 outputs an OFF signal, tape sensor Sb2 outputs an OFF signal, and tape sensor Sb3 outputs an ON signal, tape sensor Sb3 detects the component storage tape 8, so it can be determined that the component storage tape 8 is attached to the tape set position Ls. Furthermore, because tape sensors Sb1 and Sb2 output OFF signals, it can be determined that loading has not been performed on the component storage tape 8 attached to the tape set position Ls. In other words, it can be determined that the leading end of the component storage tape 8 is waiting at the tape set position Ls. In this detection state 2, loading can be performed.
[0086] In detection state 3, in which tape sensor Sb1 outputs an OFF signal, tape sensor Sb2 outputs an ON signal, and tape sensor Sb3 outputs an ON signal, it can be determined that loading is in progress for the component storage tape 8 attached to the tape set position Ls.
[0087] In detection state 4, in which tape sensor Sb1 outputs an ON signal, tape sensor Sb2 outputs an ON signal, and tape sensor Sb3 outputs an ON signal, it can be determined that loading of the component storage tape 8 attached to the tape set position Ls is complete. In this detection state 4, a component E can be supplied to the component supply unit Lf and picked up by the nozzle N.
[0088] In detection state 5, in which tape sensor Sb1 outputs an ON signal, tape sensor Sb2 outputs an ON signal, and tape sensor Sb3 outputs an OFF signal, it can be determined that the end of the component storage tape 8 has moved from tape set position Ls toward the junction J. In detection state 5, a component E can be supplied to the component supply unit Lf and picked up by the nozzle N. Alternatively, unloading can be performed by discharging the component storage tape 8 from the front end of the tape feeder 3 using the feed motor Mf.
[0089] In the detection state 6 where the tape sensor Sb1 outputs an ON signal and the tape sensor Sb2 outputs an OFF signal, it can be determined that the end of the component storage tape 8 has moved from the junction J to the component supply section Lf side.
[0090] Then, the motor control unit 330 controls the feed motor Mf and the loading motor Ml in accordance with the result of the determination by the path determination unit 340, thereby carrying out loading, component supply, or unloading.
[0091] In the tape feeder 3 having the above configuration, the feeding of the component storage tape 8 can be controlled according to the flowcharts of Figures 14A to 14C. Figure 14A is a flowchart showing a third example of control executed for the feeding of the component storage tape by the tape feeder, and Figures 14B and 14C are flowcharts showing offset setting processing executed in conjunction with the flowchart of Figure 14A.
[0092] According to the offset setting process 1 in Fig. 14B, the calculation processing unit 310 determines whether the motor control unit 330 has executed loading by using the loading motor Ml (step S311). The offset setting process 1 in Fig. 14B is executed when the tape sensor Sb3 detects the component storage tape 8 with the upper offset amount Fu and outputs an ON signal. Then, when it is determined that loading has been executed ("YES" in step S311), the calculation processing unit 310 sets the upper offset amount Fu as the offset amount used to calculate the transport amount (step S312).
[0093] According to the offset setting process 2 of Fig. 14C, the calculation processing unit 310 determines whether the output of the tape sensor Sb3 has switched from an ON signal to an OFF signal (step S321). Note that the offset setting process 2 of Fig. 14C is executed after the loading operation is performed, when the tape sensor Sb3 detects the component storage tape 8 with the upper offset amount Fu and continues to output the ON signal. Then, when it is determined that the output of the tape sensor Sb3 has switched from an ON signal to an OFF signal ("YES" in step S321), the calculation processing unit 310 sets the upper-lower offset amount Fl as the offset amount used to calculate the feed amount (step S322).
[0094] 14A, the calculation processing unit 310 determines whether the communication unit 320 has received a supply command from the communication unit 160 of the main controller 100 to instruct the supply of the component E to the component supply unit Lf. When the receipt of the supply command is confirmed ("YES" in step S301), the motor control unit 330 sets the transport amount based on one of the upper offset amount Fu and the lower offset amount Fl that is set at the time of receiving the supply command (step S302).
[0095] That is, when the upper offset amount Fu is set in step S312 of offset setting process 1 in Fig. 14B, the motor control unit 330 sets the amount obtained by adding the upper offset amount Fu to the pocket pitch T85 as the transport amount. On the other hand, when the lower offset amount Fl is set in step S322 of offset setting process 2 in Fig. 14C, the motor control unit 330 sets the amount obtained by adding the lower offset amount Fl to the pocket pitch T85 as the transport amount.
[0096] In step S03, the feed motor Mf drives the component storage tape 8 in the feed direction Df by the feed amount set in step S302, thereby supplying the component E to the component supply unit Lf.
[0097] 14A to 14C , when the component storage tape 8 driven by the feed motor Mf is transported along the upper introduction path Pu, a first transport amount (= T85 + Fu) is set, which is the pocket pitch T85 plus the upper offset amount Fu. Meanwhile, when the component storage tape 8 driven by the feed motor Mf is transported along the lower introduction path Pl, a second transport amount (= T85 + Fl) different from the first transport amount is set, which is the pocket pitch T85 plus the lower offset amount Fl. This allows components E to be supplied to stable positions regardless of the difference in the transport path between the upper introduction path Pu and the lower introduction path Pl. Thus, when the component storage tape 8 is driven by the feed motor Mf to supply the components E stored on the component storage tape 8 to the component supply unit Lf, the nozzle N can stably pick up the components E from the component supply unit Lf, regardless of the transport path used to transport the component storage tape 8.
[0098] The tape feeder 3 is also provided with a tape sensor Sb3 (first tape sensor) provided for the upper offset amount Fu. This tape sensor Sb3 outputs an ON signal (detection signal) when it detects the component storage tape 8 located at the upper offset amount Fu, and outputs an OFF signal (non-detection signal) when it does not detect the component storage tape 8 located at the upper offset amount Fu. After loading is performed while the tape sensor Sb3 is outputting the ON signal, the path determination unit 340 determines that the upper offset amount Fu is the used conveying path while the tape sensor Sb3 continues to output the detection signal (FIG. 14B), and when the output of the tape sensor Sb3 switches from the ON signal to the OFF signal, it determines that the lower offset amount Fl is the used conveying path (FIG. 14C). By performing the path determination process based on the output signal of the tape sensor Sb3 provided for the upper offset amount Fu in this manner, it is possible to accurately set one of the first conveying amount (= T85 + Fu) and the second conveying amount (= T85 + Fl) according to the path along which the component storage tape 8 is conveyed.
[0099] In the above control example, the feed amount of the component storage tape 8 for supplying the components E to the component supply unit Lf is changed depending on whether the component storage tape 8 is fed through the upper introduction path Pu or the lower introduction path Pl. However, it is also possible to change the position of the nozzle N that picks up the components E supplied to the component supply unit Lf without changing the feed amount of the component storage tape 8.
[0100] 15 is a flowchart showing an example of component mounting performed while controlling the suction position of the nozzle according to the conveyance path, and FIG. 16 is a diagram schematically showing the operations performed in accordance with the flowchart of FIG. 15. In step S401, the tape feeder 3 supplies components E to the component supply unit Lf by conveying the component storage tape 8 in the feed direction Df by a conveyance amount. The conveyance amount at this time is constant regardless of the conveyance path of the component storage tape 8. As a result, as shown in FIG. 16, the position of the component E is shifted in the feed direction Df when the component storage tape 8 conveyed along the upper introduction path Pu is driven to supply the components E and when the component storage tape 8 conveyed along the lower introduction path Pl is driven to supply the components E.
[0101] Therefore, the drive control unit 130 changes the position of the nozzle N that picks up the component E supplied to the component supply unit Lf, i.e., the suction positions Lsu and Lsl, depending on whether the component storage tape 8 transported along the upper introduction path Pu is driven to supply the component E or whether the component storage tape 8 transported along the lower introduction path Pl is driven to supply the component E. That is, when the component storage tape 8 transported along the upper introduction path Pu is driven to supply the component E, the nozzle N is positioned at the suction position Lsu to pick up the component E to the nozzle N. On the other hand, when the component storage tape 8 transported along the lower introduction path Pl is driven to supply the component E, the nozzle N is positioned at the suction position Lsl to pick up the component E to the nozzle N. The suction positions Lsu and Lsl are different positions that are shifted from each other by a distance Δ in the feed direction Df, and the suction position Lsu is located upstream of the suction position Lsl in the feed direction Df. The component E is picked up by the nozzle N positioned at the pickup positions Lsu and Lsl thus set (step S403), and is then transferred onto the board B (step S404).
[0102] 15, the tape feeder 3 is used to supply components E by a component storage tape 8 that stores components E in each of a plurality of pockets 85 (component storage sections) arranged in a row. The tape feeder 3 includes a feed motor Mf that transports the component storage tape 8 toward a predetermined component supply section Lf, and a feeder main body 31 (device main body) having an upper introduction path Pu (first transport path) and a lower introduction path Pl (second transport path) as transport paths along which the component storage tape 8 driven in the feed direction Df by the feed motor Mf is transported toward the component supply section Lf. Therefore, the force applied to the component storage tape 8 when the component storage tape 8 is transported along the upper introduction path Pu differs from the force applied to the component storage tape 8 when the component storage tape 8 is transported along the lower introduction path Pl, resulting in different supply positions of the components E. To accommodate such differences in the supply positions of the components E, the control described above sets the position of the nozzle N that picks up the components E according to the upper introduction path Pu and the lower introduction path Pl (step S403). That is, when the component storage tape 8 driven by the feed motor Mf is transported along the upper offset amount Fu, the nozzle N is positioned at the pickup position Lsu (first pickup position), whereas when the component storage tape 8 driven by the feed motor Mf is transported along the lower introduction path Pl, the nozzle N is positioned at the pickup position Lsl, which is different from the pickup position Lsu. This allows the nozzle N to stably pick up the components E from the component supply unit Lf, regardless of the transport path used to transport the component storage tape 8, when the component storage tape 8 is driven by the feed motor Mf to supply the components E stored on the component storage tape 8 to the component supply unit Lf.

In this case, the transport amounts stored in the storage unit are set as is without performing a calculation such as adding an offset. [Explanation of symbols]
