Description

Technical Field

[0001] The present invention relates to a reel holding mechanism for holding a reel around which a component supply tape is wound in a component mounting apparatus.

Background Art

[0002] In a component mounting apparatus, a tape feeder that supplies components to a predetermined component suction position by a mounting head while feeding out a ribbon-shaped component supply tape (hereinafter abbreviated as tape) in which chip-shaped components are stored is frequently used. In this case, a reel holding mechanism is used together with the tape feeder. The reel holding mechanism is a mechanism for holding a reel around which the tape is wound multiple times. The tape feeder supplies the components accommodated in the tape to the component suction position while pulling out the tape from the reel held by the reel holding mechanism.

[0003] The reel has a structure provided with disk-shaped flange portions on both sides of a central core portion (hub), and the tape is wound multiple times around the core portion in the space between the two flange portions. The reel holding mechanism holds the reel in a state of supporting the flange portion from below so that the reel rotates as the tape is pulled out and the reel can be replaced easily and quickly. Therefore, when the remaining amount of the tape decreases, a phenomenon may occur in which the reel floats (lifts up) due to the winding habit of the tape when the tape is pulled out. Such a phenomenon may inhibit the smooth pulling out of the tape by the tape feeder. It is also conceivable that the reel may fall off from the reel holding mechanism.

[0004] In order to improve this point, for example, Patent Document 1 discloses a reel holding mechanism provided with a reel floating prevention mechanism. In this reel holding mechanism, the arm member abuts on the flange portion (the outer peripheral surface thereof) from above the reel to prevent the reel from floating up.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Reels are often entirely formed of resin. In recent years, due to factors such as weight reduction and cost reduction, the strength of the flange portion of the reel tends to be structurally low. Therefore, in a conventional reel holding mechanism that prevents the reel from rising by bringing an arm member into contact with the flange portion, that is, restricts the movement range of the reel, there is a risk of deforming the flange portion. Such deformation of the flange portion, in the worst case, hinders the smooth withdrawal of the tape by the tape feeder and also becomes a factor inhibiting the reuse of the reel.

[0007] The present invention has been made in view of the above circumstances, and an object thereof is to provide a reel holding mechanism capable of restricting the movement range of a reel without deforming the reel.

Means for Solving the Problems

[0008] To solve the above problems, a reel holding mechanism according to an aspect of the present invention is a reel holding mechanism that holds a reel around which a component supply tape is wound, and includes a reel holding portion that rotatably holds the reel, and a lever member that restricts the movement range of the reel when the component supply tape is pulled out. The reel includes a shaft-shaped core portion and a pair of disk-shaped flange portions provided at both ends in the axial direction thereof, and the component supply tape is wound multiple times around the core portion in a space between the pair of flange portions. The lever member is interposed between the pair of flange portions and has a tape contact portion that restricts the movement of the reel by contacting the component supply tape wound around the core portion.

[0009] According to this reel holding mechanism, when the tape is pulled out, the movement of the reel beyond a certain range, such as the reel lifting (rising) due to the curl of the tape, is suppressed by the lever member. In particular, the lever member has a tape contact portion, and this tape contact portion is interposed between a pair of flange portions of the reel and contacts the component supply tape wound around the core portion to restrict the movement of the reel. Therefore, it is possible to restrict the movement of the reel without deforming the reel (flange portion).

[0010] In the above reel holding mechanism, the reel holding portion includes a first holding portion that holds the reel, and a second holding portion that can move and hold the reel held by the first holding portion. The lever member is disposed at a position between the first holding portion and the second holding portion and is configured to restrict the movement of the reel held by the second holding portion.

[0011] With this configuration, it is possible to hold two reels in reel holding. For example, it is possible to hold a preceding reel (sometimes referred to as a leading reel) in the second holding portion and a subsequent reel (sometimes referred to as a trailing reel) in the first holding portion. In this case, according to the above configuration, since the lever member is configured to restrict the movement of the reel held by the second holding portion, it is possible to restrict the movement caused by the lifting of the leading reel, where the remaining amount of the component supply tape is small, that is, where lifting is likely to occur.

[0012] In this case, the second holding portion is provided at a lower position than the first holding portion, and the reel holding mechanism can be configured to further include a guide portion capable of guiding the reel from the first holding portion to the second holding portion by its own weight.

[0013] According to this configuration, by pushing out the reel held by the first holding part toward the second holding part, or by the pulling force when the component supply tape is pulled out from the reel, the reel held by the first holding part can be moved from the first holding part to the second holding part by its own weight along the guide part. Then, the movement of the reel moved to the second holding part from the second holding part to the first holding part as the tape is pulled out is suppressed by the lever member.

[0014] In the above reel holding mechanism, the lever member has a rotation fulcrum at the base end part and is provided with the tape contact part at the tip end part, and is swingable around the rotation fulcrum between a first position in which it hangs down by its own weight and a second position that allows the movement of the reel from the first holding part to the second holding part, and in the first position, the tape contact part is configured to regulate the movement of the reel in the second holding part to the first holding part by contacting the component supply tape of the reel.

[0015] According to this configuration, the movement of the reel held by the second holding part to the first holding part side is suppressed.

[0016] In the above reel holding mechanism, it is preferable that the tape contact part is a roller that contacts the component supply tape.

[0017] According to this configuration, it is possible to prevent the component supply tape from being damaged when the tape contact part contacts the component supply tape.

[0018] In the above reel holding mechanism, the second holding part may be configured to hold the reel by supporting the component supply tape wound around the core part between the pair of flange parts.

[0019] According to this configuration, since the component supply tape wound around the core portion is supported from below, the reel (flange portion) is less likely to be damaged compared to the case where the flange portion of the reel is supported.

[0020] In the above-described reel holding mechanism, the cross-sectional area of the lever member in a region including the tape contact portion and other than the tip region that can be interposed between the pair of flange portions may be configured to be larger than the cross-sectional area of the tip region.

[0021] According to this configuration, while configuring the lever member so that the tape contact portion is interposed between the pair of flange portions and brought into contact with the component supply tape, it is possible to keep the strength of the lever member high.

[0022] In the above-described reel holding mechanism in which the lever member is provided so as to be swingable, a lock mechanism capable of restraining the lever member in the first position may be provided.

[0023] According to this configuration, by restraining the lever member in the first position by the lock mechanism, it is possible to regulate the unintentional movement of the reel held by the first holding portion to the second holding portion. Therefore, it is useful when a splicing operation of the tape of the subsequent reel is required after being held by the first holding portion. Note that the splicing operation is an operation of joining the tape of the subsequent reel to the tape end (rear end) of the preceding reel.

[0024] In the above-described reel holding mechanism, the tape contact portion may be configured to suppress the lifting of the reel from the reel holding portion by contacting the component supply tape of the reel.

[0025] According to this configuration, since the lifting of the reel from the reel holding portion itself is suppressed, it is possible to more stably hold the reel in the reel holding portion until the tape is completely pulled out.

Advantages of the Invention

[0026] According to the present invention described above, it is possible to provide a reel holding mechanism capable of restricting the movement range of the reel without deforming the reel.

Modes for Carrying Out the Invention

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0029] [Configuration of Component Mounting Apparatus] FIG. 1 is a cross-sectional view of a component mounting apparatus to which the present invention is applied. In the following description, for convenience, the left-right direction in FIG. 1 is defined as the front-rear direction, and the direction perpendicular to the paper surface is defined as the left-right direction.

[0030] The component mounting device 1 includes a device main body 2 and a component supply unit 4 that is detachably connected to the device main body 2.

[0031] The device main body 2 includes a base 13, a substrate transfer mechanism (not shown) for transferring a substrate such as a printed wiring board, and a head unit 12 for transferring components onto the substrate.

[0032] The central part of the base 13 is a work area WA where component mounting (installation) work is mainly performed on the substrate. The outer side (left side in FIG. 1) of this work area WA is a component supply area PA for supplying components (Surface Mount Devices) for mounting. The substrate transfer mechanism is arranged in the work area WA, and the component supply unit 4 is arranged in the component supply area PA.

[0033] The device main body 2 further includes ducts 16, 18 for guiding the used tape 11 sent out (discharged) from the following tape feeder 22 of the component supply unit 4 to the following dust box 26, and a cutter device 14 for shredding the used tape 11 guided by the ducts 16, 18, etc. The used tape 11 is the tape 11 after components have been taken out (adsorbed) by the head unit 12.

[0034] The head unit 12 is provided so as to be movable back and forth, left and right in the upper space of the base 13 across the work area WA and the component supply area PA. The head unit 12 is provided with a plurality of mounting heads 12a for component adsorption arranged side by side in the left - right direction. The head unit 12 adsorbs the components supplied by the component supply unit 4 with the mounting heads 12a and mounts them on the substrate positioned at a predetermined work position by the substrate transfer mechanism.

[0035] The component supply unit 4 includes a carriage 20, a tape feeder 22 supported by the carriage 20, and a dust box 26 for collecting the used tape 11 sent out (discharged) from the tape feeder 22.

[0036] The carriage 20 includes a bottom plate portion 30 provided with casters 32, a pair of left and right support columns 34 erected on the bottom plate portion 30, and a feeder support base 36 spanned across the upper ends of these support columns 34. A plurality of tape feeders 22 are set adjacent to each other in the left-right direction on the feeder support base 36. With this configuration, it is possible to collectively replace a plurality of tape feeders 22 for supplying components to the apparatus main body 2 by replacing the component supply unit 4.

[0037] The tape feeder 22 is a device that supplies chip-shaped components such as ICs, transistors, and capacitors, using the component supply tape 11 as a carrier. The component supply tape 11 (hereinafter abbreviated as tape 11) is arranged at the lower part behind the tape feeder 22 (the left side in FIG. 1) in a state of being wound multiple times around the reel 10. The tape feeder 22 draws out the tape 11 from the reel 10 and feeds it forward (towards the work area WA side), thereby placing the components accommodated in the tape 11 at the component supply position at the tip of the tape feeder 22, that is, the component adsorption position by the mounting head 12a.

[0038] Reinforcing members 35 are fixed to the rear portions of both support columns 34 of the carriage 20. A reel holder 24 (an example of the reel holding mechanism of the present invention) for holding the reel 10 is detachably attached to the reinforcing member 35. A plurality of reel holders 24 corresponding to the respective tape feeders 22 are attached adjacent to each other in the left-right direction to the reinforcing member 35. The reels 10 are rotatably held by these reel holders 24 respectively.

[0039] A dust box 26 is arranged below the reinforcing member 35. The dust box 26 is composed of a bottomed and rectangular box body that opens upward and is placed on the bottom plate portion 30 so as to be interposed between the two support columns 34. The used tape 11 sent out (discharged) from the tape feeder 22 is shredded by the cutter device 14 and stored and collected in this dust box 26 through the ducts 16 and 18.

[0040] Reference numeral 37 in Fig. 1 is a reel guiding member disposed below the reel holder 24. The reel guiding member 37 is a member that guides the reel 10 falling from each reel holder 24 into the dust box 26, as will be described later. In this component mounting apparatus 1, the used reel 10, that is, the reel 10 after all the tape 11 has been pulled out, is stored and collected in the dust box 26 together with the used tape 11.

[0041] [Detailed Configuration of Reel Holder 24] Fig. 2 is an external view of the reel 10, where (a) is a perspective view and (b) is a front view, each showing the reel 10. Figs. 3 to 5 show the reel holder 24, where Fig. 3 is a side view, and Figs. 4 and 5 are perspective views, each showing the reel holder 24. Note that Fig. 5 is a view with the reel 10 in Fig. 4 omitted.

[0042] As shown in Fig. 2, the reel 10 includes a columnar (axial) core portion (hub) 10a and a pair of disc-shaped flange portions 10b provided at both ends in the axial direction thereof, and its shape and the like are defined by the JEITA standard. Although omitted in Fig. 2, the tape 11 is wound multiple times around the core portion 10a in the space between the two flange portions 10b. The core portion 10a and the flange portions 10b are formed of a resin material such as PA, PP, PS, or ABS, thereby achieving weight reduction and cost reduction.

[0043] The reel holder 24 holds the reel 10 in a state where it rotatably supports the reel 10 as described above. As shown in Figs. 3 to 5, the reel holder 24 includes a holder main body portion 40 and a lever member 50. The holder main body portion 40 has a function of holding the reel 10, and the lever member 50 has a function of restricting the movement of the reel 10 held by the holder main body portion 40.

[0044] The holder main body portion 40 has a base plate 41, and components 42, 45 to 48 described later are fixed to one side (the left side surface in Fig. 4) of this base plate 41. Generally, it has a plate-like structure in which the left-right direction is the thickness direction.

[0045] At the front end of the holder main body 40, a pair of upper and lower hooks 42 are provided. These hooks 42 are formed so as to be insertable into the slit-shaped openings provided in the reinforcing member 35 and can be locked to the reinforcing member 35. By locking these hooks 42 to the reinforcing member 35, the reel holder 24 is attached to the carriage 20.

[0046] The holder main body 40 has two front and rear holding portions for holding the reel 10. Specifically, the holder main body 40 has a first holding portion 44A on the rear side and a second holding portion 44B located in front of and below the first holding portion 44A. The first holding portion 44A is mainly a place for holding the subsequent reel 10, and the second holding portion 44B is mainly a place for holding the preceding reel 10. That is, while feeding the tape 11 from the reel 10 held by the first holding portion 44A to the tape feeder 22, when the tape 11 of the reel 10 is consumed, the reel 10 is moved to the second holding portion 44B, so that the replenishing reel 10 can be held by the first holding portion 44A.

[0047] The first holding portion 44A is provided with two support members 45 and 46 that cooperate with each other to support the reel 10 from below. The support members 45 and 46 are arranged at a predetermined interval in the front-rear direction and each have a flat support surface 45a and 46b. The support members 45 and 46 are arranged such that the support surface 45a of the rear support member 45 slopes downward to the front and the support surface 46a of the front support member 46 slopes upward to the front, that is, the support surfaces 45a and 46a are V-shaped in side view.

[0048] The widths (dimensions in the left-right direction) W45 and W46 (see FIG. 5) of the support surfaces 45a and 46a are set to be slightly wider than the width W1 (see FIG. 2) of the reel 10. With this configuration, as shown in FIGS. 3 and 4, the first holding portion 44A holds the reel 10 with the reel 10 along the base plate 41 and with the outer peripheral surface of the flange portion 10b supported from below by the support members 45 and 46.

[0049] A guide member 47 (corresponding to the guide part of the present invention) is connected to the support member 46. The guide member 47 is a member that guides the reel 10 when moving the reel 10 from the first holding part 44A to the second holding part 44B. As shown in FIG. 5, the guide member 47 is a plate-shaped member having a width narrower than the width W46 of the support member 46 (support surface 46a). One end (upper end) of the guide member 47 is connected to the support member 46, extends forward and downward from the position of the support member 46, bends at about 90° at the position of the second holding part 44B, and is connected to the support member 46 again. Specifically, the support member 46 extends forward and downward from the position of the support surface 46a, the guide member 47 extends along the extending support member 46, and the other end (lower end) thereof is connected to the front end of the support member 46.

[0050] The guide member 47 is connected to the support member 46 at the center in the width direction of the support surface 46a. As described above, the guide member 47 is narrower than the support surface 46a of the support member 46, and its width W47 (see FIG. 5) is slightly smaller than the distance D1 between both flange parts 10b of the reel 10, that is, the distance between the opposing surfaces of the flange parts 10b. Therefore, a gap is formed between the guide member 47 and the base plate 41.

[0051] The guide member 47 includes a rear guide surface 47a that extends forward and downward from the front end of the support surface 46a of the support member 46 at a predetermined inclination angle θ1 with respect to the horizontal plane, and a front guide surface 47b that extends forward and downward from the rear guide surface 47a at a predetermined inclination angle θ2 (θ2 > θ1) with respect to the horizontal plane.

[0052] The second holding part 44B is provided with a support member 48 that cooperates with the guide member 47 to support the reel 10 from below. That is, the guide member 47 also has a function as a support member that supports the reel 10 in the second holding part 44B.

[0053] The support member 48 is disposed in front of the guide member 47 with a predetermined interval therebetween and the front end portion of the guide member 47. The support member 48 has a flat support surface 48a that slopes upward to the front. As a result, the support member 48 is disposed in front of the guide member 47 such that the rear guide surface 47a of the guide member 47 and the support surface 48a of the support member 48 form a V shape in side view.

[0054] The width W48 of the support member 48 including the support surface 48a (see FIG. 5) is set to be equal to the width W47 of the guide member 47. With this configuration, the second holding portion 44B holds the reel 10 in a state where the portion of the tape 11 wound around the core portion 10a of the reel 10 is supported from below by the guide member 47 and the support member 48.

[0055] Note that the interval D44 (see FIG. 3) between the tip (front end) of the guide member 47 and the tip (rear end) of the support member 48 is set to be slightly larger than the outer diameter d2 (see FIG. 2) of the core portion 10a of the reel 10. With this configuration, when the tape 11 runs out from the reel 10 held by the second holding portion 44B, the reel 10 is configured to fall through the gap between the guide member 47 and the support member 48.

[0056] The lever member 50 is disposed between the first holding portion 44A and the second holding portion 44B in the front-rear direction and above the guide member 47. The lever member 50 is a member for suppressing the lifting of the reel 10 held by the second holding portion 44B. More specifically, it is a member for restricting the movement of the reel 10 from lifting and moving from the second holding portion 44B to the first holding portion 44A.

[0057] The lever member 50 is a shaft-like member with a rectangular cross-section extending in the vertical direction. The upper end vicinity position of the lever member 50 is swingably supported by the base plate 41 via the support shaft 52. As shown in FIG. 3, the base plate 41 is provided with a stopper 56 that abuts against the lever member 50 from the rear side at a position (referred to as the first position P1) where the lever member 50 assumes a hanging posture due to its own weight. Thereby, the lever member 50 is configured such that its clockwise (clockwise in FIG. 3) swing from the first position P1 is restricted, and only counterclockwise displacement is allowed. Specifically, as will be described later, the counterclockwise displacement of the lever member 50 is allowed until it reaches a position (referred to as the second position P2) where the reel 10 can move from the first holding portion 44A to the second holding portion 44B along the guide member 47.

[0058] A tip roller 54 is rotatably provided at the tip of the lever member 50, which is the end portion on the side away from the support shaft 52. As will be described later, the tip roller 54 functions as a contact portion (tape contact portion) of the lever member 50 with respect to the tape 11 wound around the core portion 10a of the reel 10, and also functions as a guide roller for guiding the tape 11 pulled out from the reel 10 to the tape feeder 22.

[0059] As shown in FIG. 5, the lever member 50 is formed such that the width W50a of the tip side region (referred to as the tip region 50a) including the tip roller 54 is narrower than the width 50b of the base end side region (referred to as the base end region 50b). Specifically, the width W50a of the tip region 50a is slightly smaller than the distance D1 between the two flange portions 10b of the reel 10, and the width W50b of the base end region 50b is formed slightly larger than the width W1 of the reel 10. That is, the tip region 50a of the lever member 50 is formed so as to be able to be interposed between the two flange portions 10b of the reel 10, while the base end region 50b is formed so as not to be able to be interposed between the two flange portions 10b, in other words, so as to be able to abut against the outer peripheral surfaces of the two flange portions 10b.

[0060] In a state where the lever member 50 is at the first position P1, the tip of the lever member 50, that is, the tip roller 54, faces the rear guide surface 47a of the guide member 47. The lever member 50 is provided such that the distance D50 between the tip roller 54 and the rear guide surface 47a at this time is smaller than the outer diameter d2 of the core portion 10a of the reel 10.

[0061] In addition, in FIGS. 3 to 5, reference numeral 55 denotes an upper end roller rotatably provided at the upper end portion of the lever member 50. The upper end roller 55 is a guide roller that guides the tape 11 drawn out from the reel 10 to the tape feeder 22.

[0062] [Usage method and working effects of the reel holder 24] FIG. 6 is an explanatory diagram showing an example of the usage method of the reel holder 24. First, as shown in FIG. 6(a), the reel 10 is set in the first holding portion 44A, that is, the reel 10 is placed on the support surfaces 45a and 46a of the support members 45 and 46. Thereby, the reel 10 is supported by the support members 45 and 46 on the outer peripheral surface of the flange portion 10b. Usually, for the starting reel 10, since the tape 11 is wound up to near the outer periphery of the flange portion 10b, even if the reel 10 is supported by the flange portion 10b as described above, the flange portion 10b is not easily deformed.

[0063] Next, the tape 11 is pulled out from the reel 10, and with the state of passing through the upper end (upper end roller 55) of the lever member 50 at the first position P1 (hanging posture), the tip of the tape is set in the tape feeder 22. In this case, when the tape feeder 22 is an auto-loading type feeder, the tip of the tape 11 is inserted into the tape insertion port at the rear of the tape feeder 22 and held by the tape feeder 22. Thereby, when the tape feeder 22 operates, the tape 11 is automatically fed out to the component supply position. Along with the feeding out of the tape 11, the tape 11 is pulled out from the reel 10 to the tape feeder 22.

[0064] As the tape 11 is pulled out and the remaining tape amount decreases as the component mounting process progresses, the reel 10 is moved from the first holding part 44A to the second holding part 44B by pushing the reel 10 forward from the first holding part 44A. At this time, when the reel 10 is pushed forward from the first holding part 44A, as shown in FIG. 6(b), the lever member 50 swings counterclockwise from the first position P1 toward the second position P2. Thereby, the movement of the reel 10 from the first holding part 44A to the second holding part 44B becomes possible. The reason why the lever member 50 swings in this way is that the flange part 10b of the reel 10 abuts against the base end region 50b of the lever member 50 and pushes the lever member 50 forward.

[0065] The reel 10 pushed forward from the first holding part 44A moves to the second holding part 44B while rolling along the guide member 47 by its own weight. Then, when the reel 10 moves to the second holding part 44B, the lever member 50 is reset from the second position P2 to the original first position P1 accordingly.

[0066] In this case, since the width W47 of the guide member 47 is smaller than the interval D1 between both flange parts 10b of the reel 10 as described above, the reel 10 is in a state where the guide member 47 is interposed between both flange parts 10b as shown in FIG. 6(b), that is, in a state where the portion of the tape 11 wound around the core part 10a is supported by the guide member 47, and is guided from the first holding part 44A to the second holding part 44B along the guide member 47. When the remaining tape amount is small, if the reel 10 is guided while supporting the flange part 10b, it is conceivable that the flange part 10b of the reel 10 with low rigidity may be deformed such as distorted. However, as described above, by guiding the reel 10 in a state where the portion of the tape 11 wound around the core part 10a is supported by the guide member 47, the occurrence of deformation in the flange part 10b is suppressed.

[0067] The reel 10 that has moved from the first holding part 44A to the second holding part 44B is held by the second holding part 44B in a state where the portion of the tape 11 wound around the core part 10a is supported by the guide member 47 and the support member 48, as shown in FIG. 6(c). Also in this case, since the portion of the tape 11 wound around the core part 10a is supported by the guide member 47 and the support member 48, deformation such as bending in the flange part 10b is suppressed from occurring, as in the above case.

[0068] When the reel 10 moves to the second holding part 44B, in the process, the lever member 50 is reset to the first position P1 by its own weight. Thereby, the movement of the reel 10 from the first holding part 44A to the second holding part 44B is completed.

[0069] After moving the reel 10 to the second holding part 44B, a replacement reel 10 can be set in the first holding part 44A, the tape 11 can be pulled out, and the leading end of the tape can be set in the tape feeder 22.

[0070] When the remaining amount of the tape of the reel 10 held by the second holding part 44B decreases, when the tape 11 is pulled out from the reel 10, it is conceivable that the reel 10 moves from the second holding part 44B to the first holding part 44 by floating (lifting) due to the winding habit of the tape 11.

[0071] However, when the reel 10 attempts to move from the second holding part 44B toward the first holding part 44A, as shown in FIG. 7, the movement of the reel 10 is restricted by the lever member 50. That is, since the lever member 50 is restricted from rotating clockwise by the stopper 56, even if the reel 10 floats, the movement of the reel 10 is restricted by contacting the lever member 50. Specifically, as shown in FIG. 7, the tip region 50a of the lever member 50 is interposed between both flange parts 10b of the reel 10 and contacts the portion of the tape 11 wound around the core part 10a. Thereby, the movement of the reel 10 is restricted.

[0072] In this case, the distance D50 between the tip of the lever member 50, that is, the tip roller 54 and the guide member 47 (rear guide surface 47a) is smaller than the outer diameter d2 of the core 10a of the reel 10 as described above. Therefore, regardless of the remaining amount of the tape, the reel 10 will contact the lever member 50. Accordingly, when the tape 11 is pulled out, it is surely prevented that the reel 10 floats up and moves from the second holding portion 44B to the first holding portion 44A.

[0073] Moreover, since the lever member 50 contacts the tape 11 and does not contact the flange portion 10b, the lever member 50 does not contact the flange portion 10b and deform the flange portion 10b. In that case, since the lever member 50 contacts the tape 11 via the tip roller 54 provided at its tip, damage to the tape 11 due to contact with the lever member 50 is also suppressed.

[0074] Note that the distance (horizontal distance) D44 between the tip (front end) of the guide member 47 of the second holding portion 44B and the tip (rear end) of the support member 48 is set to be slightly larger than the outer diameter d2 of the core 10a of the reel 10 as described above. Therefore, when all of the tape 11 of the preceding reel 10 held by the second holding portion 44B is pulled out, as shown in FIG. 8, the reel 10 drops by its own weight from the second holding portion 44B and is finally accommodated in the dust box 26.

[0075] [Modification examples, etc.] The reel holder 24 and the component mounting apparatus 1 described above are examples of preferred embodiments of the reel holding mechanism according to the present invention and the component mounting apparatus to which the reel holding mechanism is applied, and their specific configurations can be appropriately changed without departing from the gist of the present invention. For example, the following configurations can also be applied.

[0076] (1) The reel holder 24 of the embodiment includes two holding portions (the first holding portion 44A and the second holding portion 44B) capable of holding the reel 10. However, there may be only one holding portion for the reel 10 in the reel holder 24, specifically, only the second holding portion 44B. In this case, the lever member 50 may be provided so as to be swingable such that the tip roller 54 can abut against the portion of the tape 11 wound around the core portion 10a of the reel 10 held by the second holding portion 44B by its own weight.

[0077] (2) The reel holder 24 of the embodiment is detachably attached to the carriage 20. However, when the tape feeder 22 is directly mounted on the apparatus main body 2 without passing through the carriage 20, the reel holder 24 may be detachably provided with respect to the apparatus main body 2 or fixedly (non-detachably) provided to the apparatus main body 2. Further, the reel holder 24 may be detachably provided with respect to the tape feeder 22 or integrally provided as a part of the tape feeder 22.

[0078] (3) The lever member 50 of the embodiment is formed such that the width W50b of the base end region 50b is wider than that of the tip end region 50a. That is, the lever member 50 is configured such that the cross-sectional area of the region other than the tip end region 50a (base end region 50b) is larger than the cross-sectional area of the tip end region 50a. However, the overall width (cross-sectional area) of the lever member 50 may be equal to the width W50a (cross-sectional area) of the tip end region 50a. However, according to the configuration in which the cross-sectional area of the base end region 50b is larger than the cross-sectional area of the tip end region 50a as in the embodiment, there is an advantage that the strength of the lever member 50 can be kept high while the lever member 50 is configured to be interposed between both flange portions 10b of the reel 10 and abut against the tape 11.

[0079] (4) In the embodiment, a lever member 50 is provided to prevent the reel 10 from rising (moving) from the second holding portion 44B to the first holding portion 44A. However, the lever member 50 may be configured to suppress the reel 10 held by the second holding portion 44B from rising from the second holding portion 44B (the guide member 47 and the support member 48) itself. In this case, for example, similar to the configuration described in (1) above, the lever member 50 can be provided so as to be swingable such that the tip roller 54 can contact by its own weight against the portion of the tape 11 wound around the core portion 10a among the reels 10 held by the second holding portion 44B.

[0080] FIG. 9 shows a reel holder 25 according to a modification. As shown in FIG. 9(a), this reel holder 25 has a different configuration of the lever member 50 from the reel holder 24 of the above embodiment. Specifically, the lever member 50 has an extended portion 56 in its tip region 50a. The extended portion 56 is curved and extends in an upwardly convex arc shape forward and downward from the position of the tip roller 54 in a state where the reel member 50 is disposed at the first position P1, and its tip is located below the tip roller 54 and at the center in the front-rear direction of the second holding portion 44B. The width of the extended portion 56 is equal to the width W50a of the other portions of the tip region 50a, and a second tip roller 58 equivalent to the above-described tip roller 54 (referred to as the first tip roller 54) is rotatably provided at the tip of the extended portion 56.

[0081] The basic usage method of the reel holder 25 according to the modification is the same as that of the reel holder 24 of the above embodiment.

[0082] First, as shown in Fig. 9(a), the reel 10 is set on the first holding part 44A, and the tape 11 is pulled out from the reel 10 and set on the tape feeder 22. When the remaining amount of the tape on the reel 10 decreases, as shown in Fig. 9(b), the reel 10 can be moved from the first holding part 44A to the second holding part 44B by pushing the reel 10 forward from the first holding part 44A. Also in this case, when the reel 10 is pushed forward from the first holding part 44A, the lever member 50 swings from the first position P1 to the second position P2, enabling the movement of the reel 10 from the first holding part 44A to the second holding part 44B. The reel 10 moves along the guide member 47 to the second holding part 44B under its own weight, and accordingly, the lever member 50 moves from the second position P2 to the first position P1.

[0083] At this time, in the process of the lever member 50 swinging from the second position P2 toward the first position P1, the extended part 56 of the lever member 50 is interposed between the two flange parts 10b of the reel 10. As shown in Fig. 9(c), the tip (the second tip roller 58) of the extended part 56 abuts against the tape 11 wound around the core part 10a from above. Thereby, the lifting of the reel 10 held by the second holding part 44B is suppressed.

[0084] In the reel holder 25 of the modification, since the lifting of the reel 10 is suppressed by the extended part 56 of the lever member 50 in this way, the movement of the reel 10 from the second holding part 44B to the first holding part 44A does not occur (is restricted). Even if the reel 10 is lifted, as shown in Fig. 10, the first tip roller 54 abuts against the tape 11 part of the reel 10. Thereby, the movement of the reel 10 from the second holding part 44B to the first holding part 44A is surely prevented by the lever member 50.

[0085] (5) The first holding part 44A of the embodiment is configured such that by pushing the reel 10 forward, the reel 10 moves from the first holding part 44A toward the guide member 47. However, the first holding part 44A may be configured such that when the remaining amount of the tape on the reel 10 decreases to a predetermined amount or less, that is, when the weight of the reel 10 decreases to a predetermined value or less, the reel 10 automatically moves from the first holding part 44A toward the guide member 47 due to the pulling force when the tape 11 is pulled out by the tape feeder 22. According to this configuration, it becomes possible to automatically move the reel 10 held by the first holding part 44A to the second holding part 44B.

[0086] (6) A lock mechanism capable of restraining the lever member 50 at the first position P1 may be further provided on the reel holder 24 of the embodiment. According to this configuration, for example, when the tape feeder 22 is a feeder that requires splicing, by restraining the lever member 50 at the first position P1 by the lock mechanism, it is possible to prevent the reel 10 held by the first holding part 44A from unintentionally moving to the second holding part 44B. Therefore, the convenience in performing the splicing operation is improved.
