Description

[Technical Field]

[0001] The present invention relates to a tape recovery device that recovers empty tape (used tape) fed from a tape feeder, and a component mounting device that includes the same device. [Background technology]

[0002] A tape feeder that supplies mounted components by unwinding a component supply tape that stores components at regular intervals is known. The component supply tape is composed of a carrier tape that stores components and a cover tape that covers the carrier tape. When the cover tape is peeled off from the carrier tape at a predetermined component removal position, the component can be removed.

[0003] A component mounting device equipped with a tape feeder is provided with a dust box below the tape feeder for collecting empty tape, i.e., carrier tape after components have been removed.

[0004] The empty tape delivered from the tape feeder is shredded by the tape cutter and guided through the discharge duct (duct component) into the dust box for collection. During this process, some of the shredded empty tape may adhere to the duct wall. This occurs when the cover tape peels off from the carrier tape or the carrier tape becomes statically charged due to friction between the empty tape and the duct.

[0005] If a large amount of empty tape adheres to the duct wall surface, not only will the duct become clogged, hindering the collection of empty tape, but it may also cause the tape cutter to malfunction. Therefore, for example, Patent Document 1 proposes a tape collection device equipped with a duct that has been subjected to a surface treatment to prevent the adhesion of empty tape. Patent Document 1 introduces, as examples of surface treatments, a so-called matte finish in which hard fine particles are collided with the wall surface to form irregularities of several μm to several tens of μm, and a coating of a non-stick resin such as polytetrafluoroethylene. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2018-111420 Summary of the Invention [Problem to be solved by the invention]

[0007] However, even when the duct wall surface is treated as in Patent Document 1, it is difficult to completely prevent the adhesion of empty tape to the duct wall surface, and the effectiveness of the surface treatment deteriorates surprisingly quickly due to deterioration over time caused by frequent contact with empty tape. Therefore, a method is needed that can effectively suppress the adhesion of empty tape to the duct wall surface for a longer period of time.

[0008] The present invention has been made in consideration of the above circumstances, and aims to provide a tape recovery device that can more effectively and for a longer period prevent used tape (empty tape) from adhering to the wall surfaces of duct components, and a component mounting device equipped with the same. [Means for solving the problem]

[0009] The present invention has been made in view of the above-mentioned problems. According to one aspect of the present invention, a tape collection device is provided in a component mounting device having an actuator that moves in a predetermined direction, and collects a used tape fed out from a tape feeder, the tape collection device including: a tape collection unit that collects the used tape; a duct member that guides the used tape fed out from the tape feeder to the tape collection unit; and a support member that supports the duct member, wherein the support member supports the duct member in an elastically displaceable manner so that the duct member displaces in accordance with the movement of the movable body.

[0010] In this tape collection device, used tape delivered from the tape feeder is guided and collected by a duct member to a tape collection section. The duct member is supported on a support member so as to be elastically displaceable so as to displace in accordance with the movement of the moving body. Therefore, when the moving body moves, the duct member is elastically displaced, i.e., the duct member is vibrated. This displacement shakes off the used tape from the duct member. Therefore, adhesion of the used tape to the duct member, or more precisely, the continued adhesion of the used tape to the duct member, is suppressed.

[0011] Furthermore, with this tape recovery device, the effect of preventing tape adhesion does not decrease due to deterioration of the surface treatment over time, as occurs when surface treatment is applied to duct members, making it possible to prevent used tape from adhering to duct members for the long term.

[0012] Furthermore, since the duct member is displaced by utilizing the movement of the moving body in the component mounting device, the duct member can be displaced without using a dedicated power source.

[0013] In the above-mentioned tape recovery device, it is preferable that the specified direction is a horizontal direction, and that the support member supports the duct member so that the duct member can be displaced in a direction that includes the same directional component as the specified direction.

[0014] With this configuration, since the duct member is supported so as to be displaceable in a direction that includes a directional component that is the same as the moving direction (predetermined direction) of the moving body, the duct member is more likely to be displaced when the moving body moves than when the duct member is supported so as to be displaceable in a direction that does not include the same directional component. This makes it possible to more reliably displace the duct member as the moving body moves, and ultimately to more reliably prevent the used tape from adhering to the duct member.

[0015] In the above-mentioned tape recovery device, the duct member may have a guide surface that slopes downward from one side to the other side in the specified direction, and the support member may be configured to support the duct member so that it can be displaced in a direction perpendicular to the surface of the guide surface or along the direction perpendicular to the surface.

[0016] In this configuration, the used tape is guided along the guide surface to the tape recovery section. When the movable body moves, the duct member is displaced in a direction perpendicular to the guide surface or along the direction perpendicular to the guide surface. This makes it easier for the used tape to float off the guide surface, thereby preventing the used tape from adhering to the guide surface.

[0017] In this case, the support member may be configured to support the duct member so that it can swing about a fulcrum located at a position substantially on an extension line of the guide surface in the predetermined direction.

[0018] According to this configuration, with a simple configuration for supporting the duct member so that it can swing, it is possible to displace the duct member in the direction perpendicular to the guide surface.

[0019] The tape recovery device of each of the above aspects may further include a locking mechanism that can switch the duct member between an unlocked state in which displacement of the duct member is permitted and a locked state in which displacement of the duct member is prevented.

[0020] With this configuration, in the event of an inconvenience caused by displacement of the duct member, such as abnormal noise being generated due to the displacement of the duct member, it is possible to minimize the occurrence of abnormal noise by switching the duct member to the unlocked state only when necessary.

[0021] In the tape recovery device of each of the above aspects, for example, the moving body may be a beam member that moves in the predetermined direction together with a mounting head that takes out a component from the tape feeder and mounts it on a board.

[0022] With this configuration, it is possible to use the reaction force generated by the thrust generated when the beam member (including the head), which is a relatively heavy object, moves to cause the duct member to be displaced in a driven manner. That is, the reaction force displaces the support member, which displaces the duct member, which is elastically supported by the support member.

[0023] Furthermore, in the tape recovery device of each of the above aspects, the component mounting device may include a tape cutter that cuts the used tape prior to introduction into the duct member, the moving body may be a movable blade provided on the tape cutter that moves in the predetermined direction, and the tape recovery device may further include a linkage mechanism that displaces the duct member in conjunction with the movement of the movable blade in the predetermined direction.

[0024] In this configuration, when the movable blade of the tape cutter moves, the duct member is displaced in conjunction with this movement, so that the duct member can be forcibly displaced by utilizing the movement of the movable blade of the tape cutter.

[0025] On the other hand, a component mounting device according to one aspect of the present invention comprises a beam member that moves in a predetermined direction together with a mounting head that takes components from a tape feeder and mounts them on a board, a control unit that controls the operation of the beam member, and the tape recovery device, wherein the control unit executes a component mounting process that takes components from the tape feeder and mounts them on a board, and also executes an operation process that moves the beam member in the predetermined direction while the component mounting process is paused in order to displace the duct member.

[0026] In this component mounting device, used tape delivered from the tape feeder is guided and collected by a duct member to a tape collection section. The duct member is supported on a support member so as to be elastically displaceable so as to displace in accordance with the movement of the moving body. Therefore, when the moving body moves, the duct member is elastically displaced, i.e., the duct member is vibrated. This displacement shakes off the used tape from the duct member. Therefore, adhesion of the used tape to the duct member, or more precisely, the continued adhesion of the used tape to the duct member, is suppressed.

[0027] Furthermore, with this component mounting device, the tape adhesion prevention effect does not decrease due to deterioration of the surface treatment over time, as occurs when the duct member is surface treated. Therefore, it is possible to prevent used tape from adhering to the duct member for a long period of time.

[0028] Furthermore, according to this component mounting device, the duct member is displaced by utilizing the movement of the moving body provided in the component mounting device, so the duct member can be displaced without using a dedicated power source.

[0029] In this component mounting device, the tape recovery device may further include a locking mechanism that can switch the duct member between an unlocked state in which displacement is permitted and a locked state in which displacement is prevented, and the control unit may be configured to further control the locking mechanism and control the locking mechanism so that the duct member is in the locked state while the component mounting process is being executed and the duct member is in the unlocked state while the operation process is being executed.

[0030] With this configuration, the locking mechanism is controlled so that the duct member is in the unlocked state only while the operation process is being performed, and therefore, in the event that a problem caused by displacement of the duct member, such as abnormal noise caused by the displacement of the duct member, can be minimized. [Effects of the Invention]

[0031] According to the present invention as described above, it is possible to provide a tape recovery device that can effectively prevent used tape (empty tape) from adhering to the wall surface of a duct member for a longer period of time, and a component mounting device equipped with the same.

[Figure 4] FIG. 10 is a schematic diagram showing a state in which the third duct swings (vibrates). [Figure 5] 10 is a flowchart illustrating an example of tape removal control by a control unit. [Figure 6] 10 is a cross-sectional view of a main part of a component mounting device showing the configuration of a tape recovery device of a second embodiment. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0033] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. This embodiment shows the present invention by way of example, and the present invention is not limited to the following embodiment except for its essential configuration.

[0034] [Overall configuration of component mounting device 1] FIG. 1 is a plan view of a component mounting apparatus 1 equipped with a tape collection device according to a first embodiment of the present invention. The component mounting apparatus 1 is an apparatus that produces component-mounted boards by mounting (mounting) components (Surface Mount Devices) on a substrate P such as a printed wiring board. In the drawing, an XYZ rectangular coordinate system is shown to clarify directional relationships. The X direction is parallel to a horizontal plane, the Y direction is perpendicular to the X direction on the horizontal plane, and the Z direction is perpendicular to both the X and Y directions. The Z direction may also be simply referred to as the up-down direction.

[0035] The component mounting apparatus 1 includes an apparatus main body 2, a component supply unit 4 detachably attached to the apparatus main body 2, and a tape collection device 8 (shown in FIG. 2).

[0036] The device main body 2 includes a base 20 made of a metal structure, a substrate transport mechanism 3 that transports a substrate P on the base 20, and a head unit 5 that moves in the space above the base 20.

[0037] The board transport mechanism 3 has a pair of conveyors 3a extending in the X direction. The board P is carried into the machine from the X1 side by the board transport mechanism 3, and after components are mounted at a predetermined work position (the position of the board P shown in the figure), it is transported to the X2 side and taken out of the machine.

[0038] Component supply units 4 are set on both sides in the Y direction of this board transport mechanism 3. In the component supply unit 4, a plurality of tape feeders 32 are arranged along the conveyor 3a, and components are supplied by each tape feeder 32.

[0039] The head unit 5 performs a component mounting process by suctioning (holding) components supplied by the tape feeder 32, transporting them to a work position, and mounting (placing) the components on the substrate P. The head unit 5 is equipped with multiple mounting heads 6, each equipped with a suction nozzle at its tip (lower end). The head unit 5 is equipped with a head drive mechanism (not shown) driven by a motor. The mounting heads 6 are provided so that they can rotate up and down and around a vertical axis. When removing components from the tape feeder 32, the mounting heads 6 move up and down above the tape feeder 32 to suction and hold the components. When mounting components on the substrate P, the mounting heads 6 move up and down to release the components onto the substrate P above the substrate P.

[0040] The head unit 5 moves horizontally in the space above the component supply unit 4 and the substrate P at the work position by the operation of a head unit drive mechanism 10 driven by a motor. The head unit drive mechanism 10 includes fixed rails 11 fixed to a pair of elevated frames installed on a base 20, a beam member 12 that moves in the Y direction along the fixed rails 11, and a unit support part (not shown) that moves in the X direction along the beam member 12. The head unit 5 is attached to this unit support part. The beam member 12 and the unit support member each move by the driving force of a motor. The movement of the beam member 12 and the unit support member moves the head unit 5 in the X and Y directions in the space above the base 20.

[0041] In this component mounting apparatus 1, when a board P is carried into the work position along the conveyor 3a, the head unit 5 performs the component mounting process while reciprocating between the component supply unit 4 and the board P placed at the work position. That is, the mounting head 6 takes components from the tape feeder 32, transports them to the board P, and mounts the components on the board P. When mounting of all components on the board P is completed, the board P is carried out from the work position, and the next board P is carried into the work position.

[0042] In this component mounting apparatus 1, a tape feeder 32 is provided in the component supply unit 4. The tape feeder 32 is a device that supplies small pieces of components (chip components) such as ICs, transistors, and capacitors using a component supply tape T (shown in FIG. 2) as a carrier. As components are supplied, used tape is fed from the tape feeder 32. The tape recovery device 8 is equipment provided in the component mounting apparatus 1 to recover used tape fed from the tape feeder 32 in this manner. Below, the configuration of the tape recovery device 8 will be described together with the configuration of the component supply unit 4 (tape feeder 32).

[0043] [Configuration of component supply unit 4 and tape collection device 8 (first embodiment)] Fig. 2 is a cross-sectional view of the component mounting apparatus 1 taken along line II-II of Fig. 1. That is, Fig. 2 is a view of the cross section of the component mounting apparatus 1 including the component supply unit 4 located on the Y2 side of the base 20, viewed from the X1 side. In the description of the component supply unit 4 and the tape collection device 8 based on Fig. 2, the Y direction may be referred to as the front-rear direction (the Y1 side is the front, and the Y2 side is the rear).

[0044] The component supply unit 4 includes a carriage 30, a tape feeder 32 supported by the carriage 30, and a tape recovery section 35 that recovers used tape fed (discharged) from the tape feeder 32.

[0045] The carriage 30 includes a pair of side plates 301 aligned in the X direction, a bottom plate 302 connecting the lower ends of the side plates 301, a frame 303 interposed between the pair of side plates 301 and extending in the vertical direction, and a feeder support base 304 interposed between the pair of side plates 301 and extending forward from the upper end of the frame 303. Casters 305 with a locking mechanism are provided on the underside of the bottom plate 302. This configuration allows the component supply unit 4 to move along the installation surface of the component mounting apparatus 1.

[0046] The tape feeder 32 includes a feeder main body 32a having a tape feeding mechanism driven by a motor and a cover tape peeling mechanism, and a reel 32b disposed behind the feeder main body 32a. The feeder main body 32a feeds the component supply tape T wound on the reel 32b forward while pulling it out, and peels the cover tape from the carrier tape Ta. Through this tape feeding and tape peeling operation, the components stored on the component supply tape T are placed in a component removal section 33 disposed near the front end of the feeder main body 32a.

[0047] The feeder main body 32a of each tape feeder 32 is fixed on the feeder support base 304 of the carriage 30. Meanwhile, the reel 32b is disposed behind and below the corresponding feeder main body 32a. More specifically, the rear of the frame 303 of the carriage 30 is configured as a reel holding section 34. In the reel holding section 34, a plurality of reel holders 34a are arranged side by side in the X direction, and the reels 32b are rotatably held by these reel holders 34a.

[0048] The bottom of the carriage 30, i.e., below the frame 303 and the reel holding unit 34, is a tape recovery unit 35. A dust box 36 is disposed in this tape recovery unit 35 for recovering used tape, more specifically, carrier tape Ta after components have been removed (hereinafter, may be referred to as empty tape Ta). The tape recovery unit 35, together with ducts 16 to 18 described below, constitutes a tape recovery device 8.

[0049] Although not shown, the cover tape peeled off from the carrier tape Ta is accommodated separately from the carrier tape Ta in a cover tape accommodation section provided at the rear of the feeder main body 32a.

[0050] The tape recovery device 8 includes a first duct 26, a second duct 27, and a third duct 28 that guide the empty tape Ta, a tape cutter 24 that cuts the empty tape Ta while guiding it, and the tape recovery unit 35 that recovers the empty tape Ta. The third duct 28 corresponds to the "duct member" of the present invention.

[0051] The first duct 26, the second duct 27, and the third duct 28 are cylindrical members that extend in the vertical direction and have a rectangular cross section that is elongated in the X direction, for example. The first duct 26, the second duct 27, and the third duct 28 are arranged in this order from top to bottom. The empty tape Ta delivered from the tape feeder 32 is guided downward through the first duct 26, cut by the tape cutter 24, and then guided further through the second duct 27 and the third duct 28 to the tape recovery section 35.

[0052] The first duct 26 is fixed to a support frame 21b attached to the table 21 of the base 20. The table 21 is a part of the base 20 that forms the upper surface thereof.

[0053] The upper end of first duct 26 is located in front of tape feeder 32 mounted on feeder support base 304, and the lower end is located below feeder support base 304. The upper end of first duct 26 is provided with a tape inlet opening toward tape feeder 32, and the lower end is provided with a tape outlet opening downward.

[0054] An opening 21a is formed in the table 21 below the tape outlet of the first duct 26. The second duct 27 is fixed to the underside of the table 21 at a position corresponding to the opening 21a. Therefore, the tape outlet of the first duct 26, the opening 21a of the table 21, and the upper opening 27a of the second duct 27 correspond to each other above and below. The second duct 27 has a curved shape in a side view (viewed in the X direction) so that the lower opening 27b is located on the Y2 side compared to the upper opening 27a.

[0055] The third duct 28 is disposed between the second duct 27 and the tape recovery section 35. A guide surface 28c that faces the lower opening 27b of the second duct 27 and slopes downward from the front to the rear is provided at the top of the third duct 28. As a result, the area of ​​the lower opening 28b of the third duct 28 is smaller than the area of ​​the upper opening 28a, and the third duct 28 has a generally funnel-like shape that is an inverted L in side view (viewed in the X direction) in which the lower opening 28b is biased rearward relative to the upper opening 28a.

[0056] 2, showing the periphery of the third duct 28. As shown in the figure, the base 20 has a lower frame 22 that supports the table 21, and the third duct 28 is attached to the lower frame 22 and a door member 40. The door member 40 is a plate-like member that extends vertically in a side view and closes an opening for accessing the inside of the base 20, and is fixed to the lower frame 22.

[0057] While the first duct 26 and the second duct 27 are fixed to the base 20 as described above, the third duct 28 is supported so as to be elastically displaceable relative to the base 20. More specifically, the third duct 28 has a lower rear end supported by the lower frame 22 via a hinge 42, and an upper rear end supported by the door element 40 via a coil spring 44 at a position above the hinge 42. With this configuration, as shown in FIG. 4 , the third duct 28 is supported so as to be elastically swingable about an axis extending in the X direction with the hinge 42 as a fulcrum. In this example, the lower frame 22, the door element 40, the hinge 42, and the coil spring 44 correspond to the "support member" of the present invention.

[0058] The swing fulcrum of the third duct 28, i.e., the position of the hinge 42, is set on or near an extension line L1 of the guide surface 28c in a side view (viewed in the X direction). In this example, as shown in Fig. 3, the swing fulcrum of the third duct 28 is set at a position adjacent to and below the extension line L1 of the guide surface 28c. By setting the swing fulcrum in this manner, the third duct 28 can swing in a direction perpendicular to the surface D1 of the guide surface 28c, i.e., in a direction perpendicular to the guide surface 28c (see the arrow in Fig. 4).

[0059] The tape recovery device 8 is equipped with a locking mechanism 45 for the third duct 28. The locking mechanism 45 switches the third duct 28 between an unlocked state in which its pivotal displacement is permitted and a locked state in which its pivotal displacement is prevented. The locking mechanism 45 includes a pressing member 47 that is driven to move forward and backward by an actuator 48 such as an air cylinder, and a stopper 46 that is disposed above the front end of the third duct 28.

[0060] When the locking mechanism 45 is stopped, the pressing member 47 is disposed in a retracted position away from the third duct 28. As a result, gaps that allow the third duct 28 to pivot are formed between the pressing member 47 and the third duct 28 and between the stopper 46 and the third duct 28 (the state shown in FIG. 3). Therefore, the third duct 28 is allowed to pivot within the range of these gaps (the third duct 28 is in an unlocked state).

[0061] On the other hand, when the locking mechanism 45 is activated, the pressing member 47 is disposed in the forward position, and the third duct 28 is pressed counterclockwise (counterclockwise in FIG. 3) with the hinge 42 as the fulcrum, so that the upper front end of the third duct 28 abuts against the stopper 46. As a result, the third duct 28 is prevented from being displaced (the third duct 28 is in a locked state).

[0062] The width in the X direction of each of the ducts 26 to 28 and the opening 21a of the table 21 is set to be equal to or slightly larger than the width in the X direction of the feeder support base 304, i.e., the width of the area where the tape feeders 32 are arranged. With this configuration, each of the ducts 26 to 28 can collectively guide the empty tapes Ta fed from all of the tape feeders 32 supported by the feeder support base 304 to the tape recovery section 35 (dust box 36).

[0063] The tape cutter 24 is disposed on the table 21. The tape cutter 24 includes a fixed blade 24a and a movable blade 24b that are provided facing each other in the front-rear direction, and an actuator 25 such as an air cylinder that drives the movable blade 24b in the front-rear direction.

[0064] The tape cutter 24 sandwiches and cuts the empty tape Ta delivered from the tape outlet of the first duct 26 between the fixed blade 24a and the movable blade 24b by actuation of the movable blade 24b by the actuator 25. The fixed blade 24a and the movable blade 24b extend in the X direction, and their dimensions are set so that the empty tape Ta delivered from all the tape feeders 32 supported by the feeder support base 304 can be cut all at once.

[0065] As described above, the dust box 36 is disposed in the tape recovery section 35 of the cart 30. The dust box 36 has a rectangular shape in plan view that is open at the top and is elongated in the X direction, and is configured to be able to receive empty tape Ta that drops from the lower opening 28b of the third duct 28.

[0066] The component mounting apparatus 1 is equipped with a control unit 60 that controls its overall operation. The control unit 60 is configured to include one or more ICs having a CPU as a processor, a ROM, a RAM, etc., and other memories. In the control unit 60, the CPU executes programs stored in the ROM or other memories, thereby controlling the operation of each component of the component mounting apparatus 1 and executing various arithmetic processing associated with the operation. The processor may be configured to perform processing using multiple CPUs or hardware circuits such as ASICs, in addition to one CPU, or may be configured to perform processing in cooperation with a CPU and a hardware circuit.

[0067] The control unit 60 executes the program to perform a component mounting process for mounting components on the board P and also to perform a tape removal process.

[0068] The tape removal process is a process of removing empty tape Ta adhering to the third duct 28 by vibrating the third duct 28. That is, the empty tape Ta may become statically charged due to peeling of the cover tape or friction with the ducts 26 to 28. Due to the influence of this static electricity, empty tape Ta is particularly likely to adhere to the lowest third duct 28. The tape removal process is a process for removing empty tape Ta adhering to the third duct 28 in this way. Control of this tape removal process will be described below.

[0069] [Tape removal process] 5 is a flowchart showing an example of tape removal process control by the control unit 60. The control of this flowchart is executed while the component mounting process is paused. A pause in the component mounting process refers to a period when the head unit 5 (mounting head 6) in the component mounting apparatus 1 is not substantially operating, and also includes a period when the board P is being carried in and out of the work position.

[0070] When this control is started, the control unit 60 determines whether or not an execution condition is satisfied (step S1). For example, the control unit 60 determines whether or not a condition is satisfied, such as whether a set time has elapsed since the start of the component mounting apparatus 1, or whether a specified time has elapsed since the previous tape removal process was performed.

[0071] If the determination in step S1 is Yes, the control unit 60 switches the locking mechanism 45 from ON (activated) to OFF (deactivated), thereby switching the third duct 28 from a locked state to an unlocked state (step S3). Note that the control unit 60 normally keeps the third duct 28 in a locked state by turning on the locking mechanism 45 simultaneously with starting up the component mounting apparatus 1. In this way, by keeping the third duct 28 in a locked state, the generation of abnormal noises and the like due to unintentional swinging of the third duct 28 is prevented.

[0072] When the locking mechanism 45 is switched from on to off, the control unit 60 actuates the beam member 12, causing the beam member 12 to reciprocate along the fixed rail 11 together with the mounting head 6 (step S5). In this example, the execution of the movement operation of the beam member 12 by the control unit 60 corresponds to the "operation processing" of the present invention.

[0073] The mounting head 6 and the beam member 12 are heavy objects, and when the beam member 12 moves in the Y direction together with the mounting head 6, a reaction force generated by the thrust during the movement causes displacement and deformation in the Y direction of the base 20 according to the rigidity of each part. As a result, the third duct 28, which is elastically supported on the base 20 so as to be able to swing, swings around the hinge 42 as a fulcrum. In other words, the third duct 28 is vibrated. When the third duct 28 swings (vibrates) in this manner, the empty tape Ta attached thereto is shaken off from the third duct 28 and removed from the third duct 28. The empty tape Ta shaken off from the third duct 28 is collected directly in the dust box 36.

[0074] The control unit 60 then determines whether the beam member 12 has reciprocated a set number of times (step S7). If the determination is Yes, the control unit 60 stops the beam member 12 and switches the locking mechanism 45 from OFF to ON to switch the third duct 28 from an unlocked state to a locked state (steps S9 and S11), and then ends this flowchart.

[0075] [effect] As described above, in the tape collection device 8 of the component mounting apparatus 1, the empty tape Ta (used tape) fed from the tape feeder 32 is guided by the third duct 28 and stored in the dust box 36 of the tape collection unit 35. As described above, in the tape collection device 8, the third duct 28 is supported on the base 20 (lower frame 22) via the hinge 42, the coil spring 44, and the door member 40 so as to be displaced in accordance with the movement of the beam member 12. When the control unit 60 executes the tape removal process, the beam member 12 is moved to swing (vibrate) the third duct 28, thereby shaking off the empty tape Ta from the third duct 28. Therefore, the tape collection device 8 prevents the empty tape Ta from adhering to the third duct 28, or more precisely, prevents the empty tape Ta from continuing to adhere to the third duct 28.

[0076] Moreover, since the tape recovery device 8 is configured to suppress adhesion of the empty tape Ta by displacing the third duct 28, the effect of suppressing adhesion of the empty tape Ta does not decrease due to deterioration of the surface treatment over time, as in conventional devices that suppress tape adhesion by surface treatment, and therefore it is possible to suppress adhesion of the empty tape Ta to the third duct 28 for a long period of time.

[0077] Furthermore, the tape recovery device 8 of the embodiment swings the third duct 28 by utilizing the movement of the beam member 12, and therefore, without providing a dedicated power source, the third duct 28 can be swingable by utilizing existing equipment of the component mounting apparatus 1. Therefore, the tape recovery device 8 of the embodiment can suppress the empty tape Ta from adhering to the third duct 28 with a rational configuration.

[0078] Furthermore, in the tape collection device 8 of the embodiment, the lower rear end of the third duct 28 is swingably supported on the lower frame 22 via a hinge 42, i.e., swingably about an axis in the X direction, and the upper rear end of the third duct 28 is supported on the door member 40 via a coil spring 44 at a position above the hinge 42. As a result, the third duct 28 is displaceable in a direction including a directional component that is the same as the movement direction (Y direction) of the beam member 12, as shown by the arrow in FIG. 4 . Therefore, the third duct 28 is more likely to be displaced when the beam member 12 moves, compared to a case in which the third duct 28 is supported so as to be displaceable only in a direction that does not include a directional component that is the same as the movement direction of the beam member 12, for example, only in the up-down direction. Therefore, according to the tape collection device 8, it is possible to more reliably swing the third duct 28 by utilizing the movement of the beam member 12, and therefore to more reliably prevent the empty tape Ta from adhering to the third duct 28.

[0079] Furthermore, in the tape collection device 8 of the embodiment, the third duct 28 is supported so as to be swingable in a direction (see the arrow in FIG. 4 ) along the plane-perpendicular direction D1 of the guide surface 28c (a guide surface that slopes downward from the front to the rear). In other words, when the beam member 12 moves, the third duct 28 is vibrated in the direction along the plane-perpendicular direction D1 of the guide surface 28c, which makes it easier for the empty tape Ta to float off the guide surface 28c. Therefore, the tape collection device 8 described above can effectively prevent the empty tape Ta from adhering to the guide surface 28c.

[0080] Furthermore, the tape collection device 8 of the embodiment is provided with a locking mechanism 45 that can switch the third duct 28 between an unlocked state, in which displacement of the third duct 28 is permitted, and a locked state, in which displacement is prevented. The control unit 60 controls the locking mechanism 45 so that the third duct 28 is in the locked state except when the beam member 12 is moved in the tape removal process (steps S5 to S9 in FIG. 5). This makes it possible to avoid problems such as the third duct 28 unintentionally swinging and emitting abnormal noise due to the movement of the beam member 12 during normal component mounting processing, for example.

[0081] [Configuration of the tape collection device 8 according to the second embodiment] FIG. 6 is a cross-sectional view of a main part of the component mounting apparatus 1, showing the configuration of a tape collection device 8 according to the second embodiment.

[0082] The tape collection device 8 of the second embodiment and the component mounting device 1 including the tape collection device 8 differ in configuration from the above-described tape collection device 8 and component mounting device 1 in the following points. That is, the tape collection device 8 of the first embodiment is configured to passively displace the third duct 28 by utilizing the movement of the beam member 12. In contrast, the tape collection device 8 of the second embodiment is configured to forcibly displace the third duct 28 by the operation of the tape cutter 24. Therefore, in the component mounting device 1 including the tape collection device 8 of the second embodiment, the control unit 60 does not perform the tape removal process as described above.

[0083] In the tape recovery device 8 of the second embodiment, a link member 50 is disposed above the third duct 28 and behind the second duct 27, as shown in FIG.

[0084] The link member 50 includes a pair of link bodies 51 extending in the vertical direction, a common support shaft 51a that supports the pair of link bodies 51 rotatably on the base 20, a connecting shaft 51c that connects the upper ends of each link body 51 in the X direction, and a connecting pin 51b that connects the lower ends of each link body 51 to the third duct 28.

[0085] The pair of link bodies 51 are located at both ends in the X direction of the third duct 28. Each link body 51 is supported at its vertical center by the lower frame 22 via the support shaft 51a, and the lower end of each link body 51 is rotatably connected to the edge of the upper opening 28a by the connecting pin 51b.

[0086] The connecting shaft 51c connecting the upper ends of both link bodies 51 is located directly below the movable frame 241 of the tape cutter 24. The movable frame 241 is a member that holds the movable blade 24b. The movable frame 241 is connected to the actuator 25, and is displaced in the front-rear direction by the operation of the actuator 25. As a result, the movable blade 24b moves in the front-rear direction.

[0087] A protrusion 242 that protrudes downward and extends in the X direction is provided on the lower surface of the movable frame 241. The protrusion 242 is formed in a trapezoidal cross section that tapers downward. As shown by the solid line in FIG. 6, when the tape cutter 24 is in a blade-open state in which the movable blade 24b is spaced rearward from the fixed blade 24a, the protrusion 242 is located behind the connecting shaft 51c. On the other hand, as shown by the imaginary line in FIG. 6, when the tape cutter 24 is in a blade-closed state in which the movable blade 24b overlaps the fixed blade 24a, the protrusion 242 is located in front of the connecting shaft 51c. In other words, the tape collection device 8 of the second embodiment is configured so that the protrusion 242 engages with the link member 50 as the movable blade 24b moves, thereby causing the third duct 28 to oscillate (vibrate).

[0088] More specifically, when the movable blade 24b advances from the blade-open state, the protrusion 242 abuts against the connecting shaft 51c from behind, causing the link member 50 to rotate clockwise (clockwise in FIG. 6). This rotation causes the third duct 28 to displace counterclockwise (counterclockwise in FIG. 6) around the hinge 42, i.e., in the direction in which the coil spring 44 is compressed. As the movable blade 24b advances further, the protrusion 242 climbs over the connecting shaft 51c. As a result, the compressed coil spring 44 returns to its original position, and the spring force of this spring causes the third duct 28 to swing (vibrate) clockwise around the hinge 42.

[0089] Furthermore, when the movable blade 24b retracts from the blade-closed state, the protrusion 242 abuts against the connecting shaft 51c from the front, causing the link member 50 to rotate counterclockwise. This rotation causes the third duct 28 to displace clockwise around the hinge 42, i.e., in a direction that stretches the coil spring 44. When the movable blade 24b retracts further, the protrusion 242 climbs over the connecting shaft 51c. As a result, the stretched coil spring 44 returns to its original position, and the resilient force of this spring causes the third duct 28 to swing (vibrate) counterclockwise around the hinge 42.

[0090] In this example, the link member 50 and the movable frame 241 (the protrusion 242) correspond to the "interlocking mechanism" of the present invention.

[0091] In the tape collection device 8 of the second embodiment, as described above, when the movable blade 24b of the tape cutter 24 moves, the third duct 28 swings in conjunction with this movement. Therefore, if an empty tape Ta is attached to the third duct 28, the empty tape Ta will be shaken off from the third duct 28. Therefore, in the tape collection device 8 of the second embodiment, as in the tape collection device 8 of the first embodiment, it is possible to prevent the empty tape Ta from adhering to the third duct 28.

[0092] Furthermore, in the tape collection device 8 of the second embodiment, the third duct 28 is swung by utilizing the movement of the movable blade 24b of the tape cutter 24. Therefore, it is possible to swung the third duct 28 without providing a dedicated power source, and therefore, similar to the first embodiment, it is possible to prevent the empty tape Ta from adhering to the third duct 28 with a rational configuration.

[0093] [Variations] The component mounting apparatus 1 described above is an example of a preferred embodiment of a component mounting apparatus equipped with a tape collection device according to the present invention, and the specific configurations of the component mounting apparatus 1 and the tape collection device 8 can be changed as appropriate without departing from the gist of the present invention. For example, the following configurations can also be applied.

[0094] (1) In the tape collection device 8 of the embodiment, the third duct 28 is supported on the base 20 (lower frame 22) via the hinge 42, the coil spring 44, and the door member 40 so as to be able to resiliently swing. However, the specific support structure and elastic force imparting structure of the third duct 28 are not limited to this.

[0095] For example, the third duct 28 may be configured to be supported so as to be displaceable in the Y direction relative to the lower frame 22 or the like, and to have an elastic force applied thereto by a coil spring that is expandable and contractible in the Y direction. Alternatively, the third duct 28 may be supported so as to be displaceable in the plane-perpendicular direction D1 of the guide surface 28c relative to the lower frame 22 or the like, and to have an elastic force applied thereto by a coil spring that is expandable and contractible in the plane-perpendicular direction D1. In this case, the elastic member that applies the elastic force may be a spring member other than a coil spring, or may be an elastic member such as rubber.

[0096] (2) In the tape collection device 8 of the embodiment, the third duct 28 is provided so as to be displaceable in a direction (arrow direction in FIG. 4) that includes the same directional component as the movement direction (Y direction) of the beam member 12. This is to make it easier for the third duct 28 to be displaced in accordance with the movement (movement in the Y direction) of the beam member 12. However, as long as the configuration allows the third duct 28 to be displaced in accordance with the movement of the beam member 12, it is not essential that the third duct 28 be displaceable in a direction (arrow direction in FIG. 4) that includes the same directional component as the movement direction (Y direction) of the beam member 12.

[0097] (3) Although the tape feeder 32 in the embodiment is configured to peel the cover tape from the carrier tape Ta in order to remove components, the configuration of the tape feeder is not limited to this type. For example, the tape feeder 32 may be configured to allow components to be removed by cutting the cover tape without peeling it from the carrier tape Ta.

[0098] (4) The component mounting apparatus 1 of the embodiment is configured such that the component supply unit 4 is detachably attached to the apparatus main body 2. However, the component mounting apparatus 1 may be configured such that the tape feeder 32 is mounted on the apparatus main body 2, that is, such that the tape feeder 32 is mounted directly on the apparatus main body 2 without going through the cart 30 by providing the apparatus main body 2 with a feeder support base 304.
