The reel holding device (1C) includes: a dolly (31); a first reel holding portion (61) that holds a current reel (RLA) from which a component tape (CT) is drawn out by a component supply unit (22); and a second reel holding portion (62) that is directly or indirectly coupled to the first reel holding portion (61) in a swingable manner and holds a replenishment reel (RLB) that is a replenishment reel. The first reel holding portion (61) swings relative to the dolly (31) in correspondence with an operation of the second reel holding portion (62), so that the current reel (RLA) is discharged from the first reel holding portion (61) or the replenishment reel (RLB) held by the second reel holding portion (62) is fed to the first reel holding portion (61) as a new current reel (RLA).

Description

Technical Field

[0001] The present invention relates to a reel holding device for holding a reel containing a carrier tape encapsulated with components, and a component mounting device configured to include the reel holding device. Background Technology

[0002] Conventionally, component mounting devices are known that utilize component supply units to supply components and use a working head to transfer the components onto a substrate to manufacture a mounting substrate. Various component supply units exist, but most use belt feeders that feed components into a component supply port by conveying a carrier belt containing the components. Since belt feeders pull in carrier belts drawn from a reel, a reel holding device is required in the component mounting device to hold the reel. The reel holding device typically holds not only the current reel from which the carrier belt is drawn during component supply unit transport, but also a supplementary reel used for replenishment (for example, see Patent Document 1 below).

[0003] For example, in the reel holding device described in International Publication No. 2017 / 061042, the current reel is positioned on the depth side from the operator's perspective, and the replenishment reel is positioned in front of the operator from the same perspective. The wound carrier tape on the current reel is directly supported by the reel holding device. When the carrier tape is pulled by the component supply unit, the current reel rotates in place to pull out the carrier tape. Furthermore, when all the carrier tape is pulled out, the unsupported portion automatically falls from the reel holding device and is discharged to the outside. When the used reel is discharged, the component supply unit switches the carrier tape it pulls into to the replenishment reel. The replenishment reel is pulled by the component supply unit and rotates from the standby position to the location of the original current reel, with the wound carrier tape supported by the reel holding device, thereby automatically changing the reel. Summary of the Invention

[0004] The reel holding device of the present invention holds a reel containing a carrier tape encapsulated with components and is used in conjunction with a component supply unit that feeds the carrier tape extracted from the reel in a first direction and supplies components to a work head. The reel holding device includes: a trolley; a first reel holding section that is oscillatingly disposed relative to the trolley and holds the reel; and a second reel holding section that holds a reel to be used next after the reel held in the first reel holding section. The first reel holding section and the second reel holding section are directly or indirectly connected in a oscillating manner relative to each other. Corresponding to the operation of the second reel holding section, the first reel holding section oscillates relative to the trolley, thereby discharging the reel from the first reel holding section or feeding the reel placed in the second reel holding section to the first reel holding section.

[0005] The component loading device of the present invention includes: a reel holding device that holds a reel containing a carrier tape encapsulated with components; a working head that removes components from the carrier tape and loads the components onto a substrate; and a component supply unit that feeds the carrier tape extracted from the reel in a first direction and supplies components to the working head. The reel holding device includes: a trolley; a first reel holding section that is oscillating relative to the trolley and holds the reel; and a second reel holding section that holds the reel to be used next after the reel held in the first reel holding section. The first reel holding section and the second reel holding section are directly or indirectly connected in a oscillating manner. Corresponding to the operation of the second reel holding section, the first reel holding section oscillates relative to the trolley, thereby discharging the reel from the first reel holding section or feeding the reel placed in the second reel holding section into the first reel holding section.

[0006] According to the present invention, the reel can be recovered at any time even after it has been assembled, and the reel can be easily recovered. Attached Figure Description

[0029] In conventional reel holding devices, once the current reel is assembled in the designated position, it cannot be ejected until the carrier tape is exhausted, resulting in poor workability when reel recovery is needed for production changes or adjustments.

[0030] The purpose of this invention is to provide a reel holding device and a component mounting device that allow the reel to be retrieved at any time, even after it has been assembled, and that makes the reel easy to retrieve.

[0031] Embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a side view of the component mounting device 1 according to one embodiment of the present invention. Figure 2 This is a side view of the component supply device 1B and the reel holding device 1C included in the component mounting device 1 according to one embodiment of the present invention.

[0032] The component mounting device 1 is a device for mounting component BH onto substrate KB, and includes a mounting device main body 1A, a component supply device 1B, and a reel holding device 1C.

[0033] exist Figure 1 In the middle, the main body 1A of the mounting device includes a substrate transport unit 11, a working head 12, and a head moving mechanism 13. The substrate transport unit 11 is equipped with a... Figure 1 They are arranged at intervals in the left and right directions and relative to each other. Figure 1 A pair of conveyors 11a extending perpendicularly to the paper surface are used by the substrate transport unit 11 to transport the substrate KB and position it at a predetermined working position. For ease of explanation, the transport direction of the substrate KB transported by the substrate transport unit 11 will be defined as the X direction (left-right direction), and the up-down direction as the Z direction. Furthermore, the direction orthogonal to both the X and Z directions will be defined as the Y direction (front-back direction). Moreover, in the Y direction... Figure 1 The right side is set as the front (first direction), and... Figure 1 The left side is set as the rear side.

[0034] The working head 12 has a downwardly extending nozzle 12N, and picks up part BH by supplying vacuum pressure to the nozzle 12N. The head moving mechanism 13 includes, for example, an XY stage mechanism, and moves the working head 12 in the XY plane.

[0035] The component supply device 1B includes a feeder trolley 21 and a component supply unit 22. The feeder trolley 21 has wheels and can move freely on the floor surface FL. On the upper part of the feeder trolley 21, there is a block-shaped feeder base 21F extending in the X direction (see also...). Figure 2 ).

[0036] The component supply unit 22 includes a belt feeder and is detachably mounted on the feeder base 21F. The component supply unit 22 conveys the carrier tape CT supplied from the reel holding device 1C forward in the Y direction. Multiple components BH are individually sealed in the carrier tape CT in a row. The component supply unit 22 conveys the carrier tape CT, thereby continuously supplying components BH to the component supply port 22K.

[0037] After positioning the substrate KB using the substrate transport unit 11, the main body 1A of the mounting device moves the working head 12 using the head moving mechanism 13, thereby repeatedly performing a component transfer operation to transfer the component BH supplied by the component supply unit 1B to the substrate KB. The component transfer operation includes picking up the component BH supplied by the component supply unit 22 using the nozzle 12N and mounting the picked-up component BH to the target mounting position on the substrate KB. By repeatedly performing this component transfer operation, a mounting substrate with the component BH mounted on the substrate KB is manufactured.

[0038] Next, the reel holding device 1C will be described. The reel holding device 1C is a device that holds multiple reels RL wound with carrier tape CT, and is used when connected to the feeder trolley 21. The component supply unit 22, which is mounted on the feeder trolley 21, pulls and conveys the carrier tape CT that is pulled forward (in the first direction) from the reels RL held by the reel holding device 1C, and supplies component BH to the main body 1A of the mounting device.

[0039] like Figure 1 As shown, the reel holding device 1C holds the current reel RLA and the supplementary reel RLB. The current reel RLA is the reel from which the carrier tape CT is extracted from the component supply unit 22. The supplementary reel RLB is a reel used for replenishment, that is, after the components of the current reel RLA are exhausted, the reel is used as the new current reel RLA to extract the carrier tape CT to the component supply unit 22.

[0040] Thus, in this embodiment, the reel holding device 1C holds the reel RL containing the carrier tape CT and is used in conjunction with the component supply unit 22, which feeds the carrier tape CT extracted from the reel RL forward (in the first direction) and supplies component BH to the working head 12.

[0041] Figure 3This is a side view of a reel holding device 1C according to an embodiment of the present invention. Figure 4 This is a top view of a reel holding device 1C according to one embodiment of the present invention. Figure 5 This is an exploded side view of a reel holding device 1C according to an embodiment of the present invention. Figure 3 , Figure 4 as well as Figure 5 In this device, the reel holding device 1C includes a trolley 31 and a reel holding unit 32. The trolley 31 has a pair of left and right trolley bases 41. Each trolley base 41 extends in the Y direction (front-to-back direction). Wheels 42 are respectively provided on the lower front and rear surfaces of each trolley base 41, and the reel holding device 1C can travel on the floor surface FL using these four wheels 42. A pair of left and right front support columns 43 extend upward from the middle of each of the left and right trolley bases 41, and a pair of left and right rear support columns 44 extend upward from the rear ends of each of the left and right trolley bases 41.

[0042] exist Figure 3 , Figure 4 as well as Figure 5 In the trolley 31, there is a pair of left and right arms 45 extending in the front-rear direction. Each arm 45 extends by connecting to the upper ends of the front support column 43 and the rear support column 44 of the two sets of left and right arms 44 that are arranged opposite each other in the Y direction.

[0043] exist Figure 3 , Figure 4 as well as Figure 5 In the middle, the trolley 31 has a connecting rod 46 extending in the left-right direction. The connecting rod 46 connects the left and right trolley bases 41 at the middle part. A pair of left and right clamping mechanisms 47 extending forward are provided on the connecting rod 46. The left and right clamping mechanisms 47 each have a pair of holding members 47S, which engage with the connecting pin 21P (see reference) on the feeder trolley 21 side of the forward-open slot. Figure 10 Grasp. The two gripping parts 47S are built into the clamping mechanism 47 and a spring member (not shown) applies force in the direction of mutual pressing (X direction).

[0044] exist Figure 3 , Figure 4 as well as Figure 5 In the middle, the trolley 31 has a first support rod 48 and a second support rod 49 extending in the X direction. The first support rod 48 connects the front ends of the left and right arms 45 to each other, and the second support rod 49 connects the middle parts of the left and right rear support columns 44 in the height direction to each other.

[0045] exist Figure 3 as well as Figure 5In the middle, the trolley 31 has a discharge section 51 for discharging the empty reel RL after the components are used up. The discharge section 51 has a groove-shaped shape with its two ends in the X direction connected to the left and right trolley bases 41 and recessed downwards.

[0046] exist Figure 3 , Figure 4 as well as Figure 5 In the middle, the trolley 31 has left and right alignment parts 55. Each alignment part 55 is mounted on the inner side of the front end of the left and right trolley bases 41 (the side facing each other), and has a shape that protrudes inward (the side facing each other). The distance between the inner surfaces of these left and right alignment parts 55 is a size that is slightly larger than the distance between the outer surfaces of the feeder trolley 21.

[0047] exist Figure 3 , Figure 4 as well as Figure 5 In the middle, the reel holding unit 32 is configured to include a first reel holding part 61 and a second reel holding part 62 (see also...) Figure 6 The first reel holding section 61 has the function of holding the current reel RLA, and the second reel holding section 62 has the function of holding the supplementary reel RLB.

[0048] Figure 6 This is a side view of the reel holding unit 32 included in the reel holding device 1C according to one embodiment of the present invention. Figure 5 as well as Figure 6 In this design, the first reel holding unit 61 includes a pair of plate-shaped guide members 71 facing each other in the X direction and two spacer members 72 extending in the X direction. Each spacer member 72 has a cylindrical shape and is disposed between the pair of guide members 71. Specifically, the two spacer members 72 are arranged approximately vertically at the front of the pair of guide members 71. The spacer members 72 connect the pair of guide members 71 with a distance in the X direction slightly larger than the width dimension of the reel RL (the X-direction dimension of the reel RL). Therefore, the first reel holding unit 61 can hold the reel RL within the space enclosed by the two spacer members 72 and the pair of guide members 71. The pair of guide members 71 are parallel to a vertical plane (YZ plane) along the feed direction (Y direction) of the carrier tape CT. Therefore, the first reel holding unit 61 holds the reel RL in an attitude approximately parallel to the vertical plane (upright attitude). Furthermore, the first reel holding unit 61 holds the reel RL in a rotatable state. Therefore, if the component supply unit 22 pulls in the carrier tape CT that has been drawn from the reel RL which is held parallel to the first reel holding part 61, the reel RL rotates while being held in the first reel holding part 61.

[0049] Thus, in this embodiment, the first reel holding part 61 has guide members 71 arranged at intervals that can accommodate the reel RL, and forms a structure that holds the reel RL between these pairs of guide members 71.

[0050] exist Figure 6 In this design, the first reel holding part 61 has a downwardly opening hook-shaped first engaging part 73 at the upper end of a pair of plate-shaped guide members 71, and a protruding limiting member 74 at the lower rear part of the first reel holding part 61. The base 73a of the first engaging part 73 and the base 74a of the limiting member 74 are respectively clamped and assembled by a pair of guide members. The first engaging part 73 engages with the first support rod 48 from above. Therefore, the first reel holding part 61 can swing about the first support rod 48 along the vertical plane (YZ plane) along the feed direction of the carrier tape CT.

[0051] exist Figure 5 as well as Figure 6 The second reel holding part 62 includes: a pair of guide plates 81 facing each other in the X direction; a plurality of reel receiving parts 82 disposed between the pair of guide plates 81; and a reel operating part 83 mounted on the guide plates 81. The plurality of reel receiving parts 82 include a first spacer 82a and a second spacer 82b extending in the X direction in a cylindrical shape, and a third spacer 82c extending in the Y direction in a rod-shaped shape. These three spacers (first spacer 82a, second spacer 82b, and third spacer 82c) connect the pair of guide plates 81 with a distance in the X direction slightly larger than the width dimension of the reel RL. Therefore, the second reel holding part 62 can hold the reel RL within the space enclosed by the three spacers (first spacer 82a, second spacer 82b, and third spacer 82c) and the pair of guide plates 81.

[0052] A pair of guide plates 81 are parallel to the vertical plane (YZ plane) along the feed direction (Y direction) of the carrier tape CT. Therefore, the second reel holding part 62 can hold the reel RL in an upright posture that is approximately parallel to the vertical plane along the feed direction of the carrier tape CT. In addition, the second reel holding part 62 holds the reel RL in a rotatable state. Thus, if the component supply unit 22 pulls in the carrier tape CT that has been withdrawn from the reel RL held in the second reel holding part 62, the reel RL rotates while being held in the second reel holding part 62.

[0053] In the second reel holding section 62, the reel receiving section 82, comprising three spacers (first spacer 82a, second spacer 82b, and third spacer 82c), abuts against the reel RL located between a pair of guide plates 81, thereby supporting the reel RL within the second reel holding section 62. In the second reel holding section 62, the space enclosed by the pair of guide plates 81 and the reel receiving section 82 comprising the three spacers (first spacer 82a, second spacer 82b, and third spacer 82c) forms an upwardly opening supplementary reel placement space HRS that accommodates the supplementary reel RLB. Figure 6 ).

[0054] Thus, in this embodiment, the second reel holding part 62 includes: a pair of guide plates 81, which are arranged at intervals to accommodate the reel RL; and a plurality of reel receiving parts 82, which abut against the reel RL between the pair of guide plates 81. The second reel holding part 62 is structured to hold the reel RL in the space surrounded by the pair of guide plates 81 and the plurality of reel receiving parts 82.

[0055] Figure 7 This is a side view of the reel holding unit 32 of the reel holding device 1C in one embodiment of the present invention, in the first position. Figure 6 as well as Figure 7 In this design, the rear end (operator side) of the reel operating section 83 is fixed and disposed at the lower part of the guide plate 81, and the front end (parts supply device 1B side) of the reel operating section 83 protrudes forward from the guide plate 81 and extends into the space sandwiched by a pair of guide members 71. The middle portion of the portion of the reel operating section 83 that protrudes forward from the guide plate 81 (hereinafter referred to as "protrusion 83T") is pivotally (flexibly coupled) to the guide member 71 of the first reel holding section 61 via a connecting portion 84 extending in the X-axis direction. Therefore, the second reel holding section 62 can swing along a vertical plane (YZ plane) along the feed direction of the carrier tape CT, and thus the reel operating section 83 can also swing within this vertical plane (YZ plane). The front end portion 83S, which extends away from the second reel holding section 62 from the connecting portion 84 of the protrusion 83T, enters the space sandwiched by the pair of guide members 71 and is located above the limiting member 74.

[0056] Thus, in this embodiment, the first reel holding part 61 and the second reel holding part 62 are directly connected in a swingable manner, and the first reel holding part 61 and the second reel holding part 62 form a linkage mechanism.

[0057] exist Figure 6 as well as Figure 7 In the middle, a downwardly opening hook-shaped second engaging portion 85 is formed at the lower rear part of a pair of guide plates 81. The second engaging portion 85 can engage from above with the second support rod 49 ( Figure 7 ).

[0058] Return to Figure 5 The reel holding unit 32 includes a supported portion (a first engaging portion 73 and a second engaging portion 85) supported on the reel holding unit support portion (a first support rod 48 and a second support rod 49). The reel holding unit 32 engages and supports the supported portion (a first engaging portion 73 and a second engaging portion 85) from above on the reel holding unit support portion (a first support rod 48 and a second support rod 49). Specifically, the reel holding unit support portion (a first support rod 48 and a second support rod 49) engages the first engaging portion 73 from above with the first support rod 48 and the second engaging portion 85 from above with the second support rod 49, thereby supporting the reel holding unit 32.

[0059] The first support rod 48 and the second support rod 49 are rod-shaped members without protrusions or recesses on their outer periphery. The supported portions (first engaging portion 73 and second engaging portion 85) can slide along the first support rod 48 and the second support rod 49. Therefore, the reel holding unit 32, supported by the first support rod 48 and the second support rod 49, can move along the first support rod 48 and the second support rod 49 while supported by the reel holding unit support portion (first support rod 48 and second support rod 49). That is, the reel holding unit support portion (first support rod 48 and second support rod 49) can hold multiple reel holding units 32 along their arrangement direction (…). Figure 4 The reel holding unit 32 is supported in a state where it can slide freely (as indicated by the arrow W). Therefore, the operator can change the position of the arrangement direction (X direction) without removing the reel holding unit 32 from the reel holding unit support (first support rod 48 and second support rod 49).

[0060] Thus, the reel holding device 1C in this embodiment includes: a reel holding unit 32 that holds the reel RL; and a reel holding unit support (first support rod 48 and second support rod 49) that holds a plurality of reel holding units 32 in a parallel direction in which a plurality of component supply units 22 are arranged side by side. The reel holding unit support includes two support rods (first support rod 48 and second support rod 49) extending in the parallel direction of the reel holding units 32. The reel holding unit 32 is configured to slide in the parallel direction of the component supply units 22 by engaging the first engagement portion 73 and the second engagement portion 85, which are supported portions, from above with these first support rods 48 and second support rods 49.

[0061] Conventionally, the assembly position of the reel holding unit 32 in the reel holding unit support (first support rod 48 and second support rod 49) is limited to multiple mounting slots divided in the X direction. When changing the mounting position, the reel holding unit 32 needs to be removed from the existing mounting slot and reassembled into another mounting slot. In contrast, in the reel holding unit support (first support rod 48 and second support rod 49) of this embodiment, there is no such concept of slots. Therefore, the reel holding unit 32 can be assembled in a convenient position and supported in a sliding state. Thus, even after assembly, it is easy to temporarily move the reel for repositioning, inspection, or confirmation. Therefore, a reel holding device 1C with superior operation compared to conventional devices can be provided.

[0062] exist Figure 7 In this configuration, the reel holding unit 32, supported by the reel holding unit support (first support rod 48 and second support rod 49), bends around the connecting part 84 under its own weight, and assumes a posture in which the front end 83S of the reel operating part 83 faces downward. Hereinafter, this posture, in which the second engaging part 85 of the second reel holding part 62 engages with the second support rod 49 and the reel operating part 83 faces downward, will be described. Figure 7 The position of the reel holding unit 32 in the posture shown is referred to as the "first point". Furthermore, the posture of the second reel holding unit 62 with the front end 83S of the reel operating unit 83 facing downwards will be described below. Figure 7 This is called the "downward posture".

[0063] Figure 8 This is a side view of the reel holding unit 32 of the reel holding device 1C in one embodiment of the present invention, in the state of being at the second position. If the operator moves from the state where the reel holding unit 32 is at the first position... Figure 7 Grasp the rear end of the second reel holding part 62 and lift it diagonally upwards and backwards. Figure 8 As shown by arrow P1, the second engaging portion 85 of the second reel holding portion 62 disengages from the second support rod 49, and the first reel holding portion is pulled upwards and backwards by the second reel holding portion 62 via the connecting portion 84. Furthermore, when the limiting member 74 of the first reel holding portion 61 abuts against the second support rod 49 from below, the second reel holding portion 62 cannot be pulled up further. Figure 8 ).

[0064] The following describes the position of the reel holding unit 32 in an orientation where the second reel holding part 62 is pulled backward and upward, and the limiting member 74 of the first reel holding part 61 abuts against the second support rod 49. Figure 8This is referred to as the "second position". It should be noted that when the second reel holding part 62 is located at the second position, the second reel holding part 62 maintains a downward posture that keeps the front end part 83S of the reel operating part 83 downward.

[0065] Figure 9 This is a side view of the reel holding unit 32 of the reel holding device 1C in one embodiment of the present invention, in the state of being at the third position. If the operator moves from the state where the reel holding unit 32 is in the "second position" (… Figure 8 Lower the rear end of the second reel holder 62 downwards. Figure 9 As shown by arrow P2), the reel operating section 83 abuts against the second support rod 49 from above. Then, the reel operating section 83 maintains its contact with the second support rod 49 and swings backward and downward around the connecting section 84. Furthermore, when the second support rod 49 is clamped between the limiting member 74 and the reel operating section 83, the operator is unable to lower the second reel holding section 62 further. Figure 9 ).

[0066] Hereinafter, the position of the reel holding unit 32 when it is impossible to lower the second reel holding section 62 further will be described as follows. Figure 9 This is referred to as the "third position". Furthermore, when the reel holding unit 32 is at the third position, the second reel holding part 62 is positioned such that the front end portion 83S of the reel operating part 83 faces upwards. Hereinafter, the posture of the second reel holding part 62 with the reel holding unit 32 at the third position and the front end portion 83S of the reel operating part 83 facing upwards will be described. Figure 9 This is called the "upward posture".

[0067] exist Figure 2 In the component supply device 1B, the feeder trolley 21 has a receiving space 21S with a rearward opening at its center. In addition, the feeder trolley 21 has a horizontal stack 21B extending in the X direction at its rear, and the aforementioned pair of left and right connecting pins 21P protruding downward and extending on the lower surface of the horizontal stack 21B.

[0068] Figure 10 This is a top view of the state before the reel holding device 1C is connected to the feeder trolley 21 of the component supply device 1B, according to one embodiment of the present invention. When the reel holding device 1C is connected to the feeder trolley 21 of the component supply device 1B, the operator first... Figure 10 The reel holding device 1C is positioned behind the feeder trolley 21. At this time, the reel holding unit 32 is pre-positioned at the first position.

[0069] Figure 11A as well as Figure 11B This is a side view showing the connection between the reel holding device 1C and the feeder trolley 21 of the component supply device 1B according to an embodiment of the present invention. After the operator positions the reel holding device 1C behind the feeder trolley 21, the operator gradually moves the reel holding device 1C closer to the feeder trolley 21. Figure 11A → Figure 11B As a result, the tip of the reel holding device 1C (the tip of the left and right trolley bases 41) gradually moves toward the interior of the feeder trolley 21 with the inner surface of the left and right alignment parts 55 guided by the outer surface of the feeder trolley 21.

[0070] As the reel holding device 1C gradually moves towards the interior of the feeder trolley 21, the tip of the reel holding device 1C is laterally (in the X direction) positioned relative to the feeder trolley 21 by the left and right alignment parts 55. Furthermore, as the reel holding device 1C moves further, the connecting rod 46 of the trolley 31 abuts against a predetermined part of the feeder trolley 21 from the rear, and is positioned in the front-to-back (Y direction).

[0071] Figure 12 This is a top view of the feeder trolley 21 in one embodiment of the present invention, showing the reel holding device 1C connected to the component supply device 1B. When the trolley 31 is positioned relative to the feeder trolley 21 in the Y direction, the left and right connecting pins 21P provided on the feeder trolley 21 are inserted between the left and right gripping members 47S of the left and right clamping mechanisms 47 provided on the reel holding device 1C. Thus, the left and right connecting pins 21P are clamped by the left and right clamping mechanisms 47. Figure 12 The reel holding device 1C is connected to the feeder trolley 21. Figure 11B It should be noted that if the trolley 31 is pulled backward from the feeder trolley 21 from the state where the connecting pin 21P is clamped by the clamping mechanism 47, the left and right holding parts 47S can be pushed open by the connecting pin 21P, the clamping can be released and the trolley 31 can be separated from the feeder trolley 21.

[0072] like Figure 2 As shown, when the reel holding device 1C is connected to the feeder trolley 21, the front part of the first reel holding section 61 of the reel holding unit 32 of the reel holding device 1C is located within the receiving space 21S of the feeder trolley 21. Furthermore, the rear part of the first reel holding section 61 is located at the rear of the feeder trolley 21.

[0073] Figure 13This is a side view showing the assembly of the current reel RLA and the supplementary reel RLB into the second reel holding section 62 of the reel holding device 1C according to one embodiment of the present invention. After the reel holding device 1C is connected to the feeder trolley 21 as described above, the operator holds the reel RL in the reel holding unit 32. To do this, firstly, the second reel holding section 62 in the reel holding unit 32, which is in the first position, is lifted rearward and upward (…). Figure 7 → Figure 8 This allows the reel holding unit 32 to be positioned at the second location ( Figure 8 Furthermore, after the reel holding unit 32 is located at the second position, the operator lowers the rear end of the second reel holding part 62. Figure 8 → Figure 9 This allows the reel holding unit 32 to be positioned at the third location ( Figure 9 as well as Figure 13 ).

[0074] like Figure 13 As shown, with the reel holding unit 32 located at the third position, the second reel holding portion 62 is in an upward posture with the front end 83S of the reel operating portion 83 facing upward. In this upward posture, a working space SGS (for mounting the reel RL) appears in the area between the reel operating portion 83 (specifically, the protrusion 83T) and a portion of the reel receiving portion 82 (the first spacer 82a) on the second reel holding portion 62. Figure 13 ).

[0075] After creating a work space SGS on the reel holding unit 32 by positioning the reel holding unit 32 at the third position (setting the second reel holding part 62 in an upward orientation), the operator places the reel RL, which will become the current reel RLA, into the work space SGS, and places the reel RL, which will become the supplementary reel RLB, into the supplementary reel placement space HRS. Figure 13 ).

[0076] Figure 14 This is a side view showing the state in which the current reel RLA and the supplementary reel RLB are assembled in the second reel holding part 62 of the reel holding device 1C according to an embodiment of the present invention. After the operator places the reel RL into the workspace SGS, the carrier tape CT is pulled out from the reel RL. The tip of the pulled-out carrier tape CT is then inserted into the tape insertion port 22G at the rear of the component supply unit 22 mounted on the feeder base 21F of the feeder trolley 21. Figure 14 ).

[0077] Thus, in this embodiment, the work space SGS that appears by positioning the reel holding unit 32 at the third position becomes a work space for the operator to place the reel RL and perform the operation of pulling out the carrier tape CT from the placed reel RL and inserting it into the component supply unit 22.

[0078] If the tip of the carrier tape CT, pulled from the reel RL placed in the workspace SGS, is inserted into the tape insertion port 22G of the component supply unit 22, the component supply unit 22 begins pulling in the carrier tape CT. As a result, the reel RL on the workspace SGS is pulled forward (towards the component supply unit 22) by the carrier tape CT, and then the reel RL becomes the current reel RLA.

[0079] The reel RL, which is now the working space SGS of the current reel RLA, is rotated by the component supply unit 22 pulling the carrier tape CT forward. However, the front end 83S of the reel operating section 83 is upward, so the current reel RLA rotates on the reel operating section 83, i.e., on the working space SGS (rotates in place). That is, after the component supply unit 22 starts pulling in the carrier tape CT of the reel RL on the working space SGS, the second reel holding section 62 also maintains the state of holding the reel RL on the working space SGS.

[0080] Figure 15 This is a side view showing the feeding of the current reel RLA from the second reel holding section 62 to the first reel holding section 61 in one embodiment of the present invention. After the operator inserts the tip of the carrier tape CT, which has been pulled out of the reel RL (current reel RLA) placed in the workspace SGS, into the component supply unit 22, the second reel holding section 62 is lifted ( Figure 14 → Figure 15 Therefore, the reel holding unit 32 swings around the connecting part 84 and is positioned at the second point. Figure 15 ).

[0081] With the reel holding unit 32 located at the second position, the second reel holding part 62 is in a downward orientation with the front end 83S of the reel operating part 83 facing downward. If the second reel holding part 62 changes from an upward orientation to a downward orientation, the current reel RLA placed in the workspace SGS moves forward and downward under its own weight while being guided by the reel operating part 83, and is housed between the pair of guide members 71 constituting the first reel holding part 61. Figure 15 ).

[0082] exist Figure 15In the middle, in the front portion of the outer periphery of the current reel RLA housed within the first reel holding portion 61, it abuts against the lower side of one of the two spacer members 72 (constituting the first reel holding portion 61) provided in the first reel holding portion 61. Figure 15 The spacer member (represented by reference numeral "72a") abuts against the front end 83S of the reel operating section 83. Thus, the current reel RLA is supported between the spacer member 72 and the reel operating section 83 between a pair of guide members 71 of the first reel holding section 61. Figure 15 ).

[0083] Thus, in this embodiment, the spacer member 72 becomes an abutting portion that abuts against the portion of the reel RL held in the first reel holding portion 61 that is in front (i.e., the first direction side) when viewed from the central axis of the reel RL.

[0084] In addition, in this embodiment, the second reel holding part 62 can change between an upward posture (first posture) in which the front end 83S of the reel operating part 83 is raised and a downward posture (second posture) in which the front end 83S of the reel operating part 83 is lowered relative to the first reel holding part 61. When the second reel holding part 62 is in the upward posture, it has a working space SGS that can hold the reel RL and can maintain the reel RL even after the component supply unit 22 starts pulling in the carrier tape CT. When the second reel holding part 62 is in the downward posture, the reel RL placed in the working space SGS is guided by the reel operating part 83 and fed into the first reel holding part 61.

[0085] Therefore, by selecting the time when the second reel holder 62 changes from an upward to a downward position, the operator can move the reel RL in the workspace SGS towards the first reel holder at any time. In other words, the operator can manually feed the reel RL in the workspace SGS towards the first reel holder 61. Therefore, it prevents the current reel RL from moving towards the first reel holder 61, which is out of the operator's reach, while the operator is not paying attention.

[0086] For the supplementary reel RLB held within the supplementary reel mounting space HRS of the second reel holding section 62, it remains held within the supplementary reel mounting space HRS even when the reel operation section 83 changes from an upward posture to a downward posture. Specifically, when the second reel holding section 62 changes from an upward posture to a downward posture, the supplementary reel RLB within the supplementary reel mounting space HRS moves forward and downward along the third spacer 82c, but becomes stationary upon contact with the first spacer 82a and maintains this state. Figure 15 ).

[0087] Figure 16 This is a side view showing the current reel RLA of the reel holding device 1C according to an embodiment of the present invention in a component supply state. After the operator feeds the reel RL (current reel RLA) on the workspace SGS into the first reel holding part 61 as described above, the second reel holding part 62 is moved forward and downward close to the first reel holding part 61. Figure 16 (See arrow P3). Furthermore, by engaging the second engagement portion 85 provided in the second reel holding portion 62 with the second support rod 49 of the trolley 31, the reel holding unit 32 is positioned at the first point (…). Figure 16 During this period, the operation of the second reel holding part 62 (reel operating part 83) causes the first reel holding part 61 to swing about the first support rod 48 in a direction that raises the front end side, and the current reel RLA is in a state where part of its front half is located in the receiving space 21S of the feeder trolley 21. Figure 16 ).

[0088] If the reel holding unit 32 is located at the first point, the current reel RLA is in a state where the front end is supported by the abutment portion formed by the spacer member 72 provided in the first reel holding part 61, and the rear end is supported by the concave bottom surface 21M of the feeder trolley 21 that forms the receiving space 21S. Figure 16 In this state, the center of gravity GV of the current reel RLA is located between the abutment portion (spacer member 72) and the rear end of the bottom surface 21M. Therefore, even if the carrier tape CT of the current reel RLA is pulled out by the component supply unit 22 and a rotational force is applied to the current reel RLA under the tension of the carrier tape CT, the current reel RLA rotates in a stable state on the spot.

[0089] As described above, even if the reel holding unit 32 is displaced from the second point to the first point, the supplementary reel RLB in the supplementary reel mounting space HRS remains in the state of being within the supplementary reel mounting space HRS. Figure 16 After the reel holding unit 32 is in the first position, the operator pulls the carrier tape CT from the supplementary reel RLB and pre-inserts its tip into the tape insertion port 22G of the component supply unit 22. Figure 16 ).

[0090] Figure 17 This is a side view showing the current reel RLA of the reel holding device 1C in one embodiment of the present invention in a state where the parts are exhausted. The part supply device 1B pulls and conveys the carrier tape CT from the current reel RLA held by the first reel holding part 61 located at the first position, thereby supplying the part BH. Figure 16After the current reel RLA is exhausted due to the supply of component BH by component supply unit 22, that is, after the carrier tape CT of the current reel RLA is exhausted, the current reel RLA becomes a used reel RL. Therefore, component supply unit 22 switches the pull-in object to the carrier tape CT extracted from the supplementary reel RLB placed in the supplementary reel placement space HRS, and continues to supply component BH. Figure 17 ).

[0091] After the component supply unit 22 pulls the carrier tape CT into the supplementary reel RLB placed in the supplementary reel placement space HRS, the previous supplementary reel RLB is switched to the current reel RLA. The newly created reel RL, which becomes the current reel RLA, rotates (rotates in place) within the supplementary reel placement space HRS. That is, the second reel holding unit 62 maintains the state of holding the reel RL in the supplementary reel placement space HRS after the component supply unit 22 begins pulling in the carrier tape CT of the reel RL in the supplementary reel placement space HRS.

[0092] Figure 18 This is a side view showing the situation before the used reel is ejected from the reel holding device according to one embodiment of the present invention. After confirming that the component supply unit 22 has started pulling in the carrier tape CT of the current reel RLA on the reel loading space HRS, the operator performs the operation of ejecting the used reel RL from the first reel holding section 61. To do this, firstly, the operator lifts the second reel holding section 62 backward and upward ( Figure 18 Arrow P1 shown), and displaces the reel holding unit 32 toward the second position ( Figure 18 ).

[0093] If the reel holding unit 32 is displaced to the second position, the reel operating part 83 and the second reel holding part 62 move backward and upward as a single unit, and the first reel holding part 61 is also lifted to the rear end side via the connecting part 84. Figure 18 Therefore, the first reel holding part 61 swings about the first support rod 48 in the direction that lowers the front end, and the used reel RL moves behind the receiving space 21S of the feeder trolley 21, i.e., the reel discharge position, under the action of the spacer member 72 which serves as the abutment part. Figure 18 At the moment when the reel holding unit 32 is displaced to the second position, the straight-line distance connecting the spacer member 72 to the front end 83S of the reel operating part 83 is smaller than the outer diameter of the reel RL. Therefore, the used reel RL, which has moved to the discharge position, does not fall but stops at the discharge position.

[0094] Figure 19This is a side view showing the reel holding device 1C of an embodiment of the present invention discharging a used reel RL. After the used reel RL is moved to the discharge position, the operator moves the rear side of the second reel holding part 62 downward. Figure 19 (See arrow P2). Consequently, the second reel holding part 62 swings within the YZ plane around the second support rod 49, the reel holding unit 32 shifts to the third position, and the second reel holding part 62 assumes an upward posture. Figure 19 ).

[0095] If the second reel holding part 62 is in an upward position, the straight-line distance connecting the front end 83S of the reel operating part 83 to the spacer member 72 is larger than the outer diameter of the reel RL. Therefore, the used reel RL falls downward from the discharge position under its own weight and is discharged to the discharge part 51. Figure 19 It should be noted that, as described above, the spacer member 72, which serves as the abutment part, presses the used reel RL backward to move it toward the discharge position, but "backward" refers to the direction opposite to the feed direction of the carrier tape CT, i.e., the front (first direction).

[0096] Thus, in the reel holding device 1C of this embodiment, the used reel RL is not automatically discharged, but is discharged by the operator according to the operator's instructions.

[0097] As can be seen from the above description, when the second reel holding part 62 is in a downward posture (second posture), the position of the reel operating part 83 is the position that prevents the reel RL held in the first reel holding part 61 from being discharged from the first reel holding part 61 (first position). Figure 18 When the second reel holding part 62 is in an upward posture (first posture), the position of the reel operating part 83 is a position that allows the reel RL of the first reel holding part 61 to be discharged from the first reel holding part 61 (second position). Figure 19 ).

[0098] That is, in the reel holding device 1C of this embodiment, if the reel holding unit 32 is displaced from the second position to the third position, and the second reel holding part 62 changes from a downward posture to an upward posture, then the reel operating part 83 provided in the second reel holding part 62 is displaced from the position (first position) that prevents the current reel RLA held in the first reel holding part 61 from being discharged to the discharge part 51, to the position (second position) that allows the current reel RLA, which has moved under the action of the spacer member 72 as the abutment part, to be discharged to the discharge part 51. Figure 18 → Figure 19 ).

[0099] In this embodiment, the second reel holding portion 62 functions as an operating mechanism that moves the spacer member 72, which serves as the abutment portion, rearward to discharge the current reel RLA from the first reel holding portion 61. That is, by swinging the second reel holding portion 62, which serves as the operating mechanism, relative to the first reel holding portion 61, the reel operating portion 83 provided in the second reel holding portion 62 is displaced between a first position that prevents the reel RL held in the first reel holding portion 61 from being discharged from the first reel holding portion 61 and a second position that allows the reel RL, which has moved under the action of the spacer member 72, which serves as the abutment portion, to be discharged from the first reel holding portion 61.

[0100] Figure 20 This is a side view showing a scenario in which a supplementary reel RLB is reassembled into the reel holding device 1C as a new current reel RLA, according to an embodiment of the present invention. Figure 21 This is a side view showing the assembly of a new replenishment reel RLB into the reel holding device 1C according to an embodiment of the present invention. After the used reel RL is discharged to the discharge section 51 by being moved from the second position to the third position by the reel holding unit 32, the operator removes the new reel RL, which becomes the current reel RLA, from the replenishment reel placement space HRS. Figure 19 Arrow L shown indicates that the SGS is positioned in the resulting workspace. Figure 20 Furthermore, the newly supplemented supplementary reel RLB is placed in the newly empty supplementary reel placement space HRS. Figure 21 Thus, it becomes the same as the aforementioned. Figure 14 Because of the same state, the component supply operation of component supply unit 22 can be continuously performed by repeatedly executing the same operation.

[0101] Thus, the reel holding device 1C in this embodiment includes: a trolley 31; a first reel holding section 61, which is oscillatingly disposed relative to the trolley 31 and holds the current reel RLA; and a second reel holding section 62, which is oscillatingly directly coupled to the first reel holding section 61 and holds the supplementary reel RLB. If the second reel holding section 62 is operated, the first reel holding section 61 oscillates relative to the trolley 31 accordingly, so that the used reel RL is discharged from the first reel holding section 61, or the supplementary reel RLB placed in the second reel holding section 62 is fed to the first reel holding section 61 as a new current reel RLA.

[0102] Therefore, in the reel holding device 1C of this embodiment, even after the reel RL (current reel RLA) is assembled to the first reel holding part 61, the reel RL can be retrieved at any time and is easy to retrieve, improving workability when it is necessary to retrieve the reel RL in use, such as during production changeovers. Furthermore, since the first reel holding part 61 and the second reel holding part 62 constitute a reel holding unit 32, and this reel holding unit 32 is mounted on the trolley 31, the structure of the reel holding device 1C is simple and easy to maintain.

[0103] Furthermore, in this embodiment, a work space SGS is formed that holds the reel RL before it is fed into the first reel holding part 61 and allows the reel RL to rotate in place. Therefore, after the operator performs part alignment work in the work space SGS, the reel RL can be fed into the first reel holding part 61 at any time.

[0104] As described above, the reel holding device 1C in this embodiment includes: a trolley 31; a first reel holding section 61 that holds the current reel RLA pulled out by the component supply unit 22 of the carrier tape CT; and a second reel holding section 62 that is directly or indirectly coupled to the first reel holding section 61 in a swingable manner and holds the supplementary reel, i.e., the supplementary reel RLB. Furthermore, if the second reel holding section 62 is operated, the first reel holding section 61 swings relative to the trolley 31 accordingly, so that the current reel RLA is discharged from the first reel holding section 61, or the supplementary reel RLB held in the second reel holding section 62 is fed to the first reel holding section 61 as a new current reel RLA. Therefore, even after the reel RL (current reel RLA) is assembled to the first reel holding section 61, the reel RL can be retrieved at any time and is easily retrieved, improving workability when the reel RL needs to be retrieved during production changeovers or other adjustments.

[0105] The embodiments of the present invention have now been described, but the present invention is not limited to the above description and various modifications are possible. For example, in the above embodiment, an abutment portion that abuts against the outer periphery of the current reel RLA held in the first reel holding portion 61 and moves the current reel RLA is provided in the first reel holding portion 61. However, the abutment portion may not necessarily be provided in the first reel holding portion 61, or it may be provided in a mechanism that swings independently of the first reel holding portion 61 around the X-axis. In the above embodiment, since the abutment portion that presses the used reel RL backward is a component constituting the first reel holding portion 61, it becomes a structure in which the first reel holding portion 61 swings around the first support rod 48, thereby moving the abutment portion backward. However, the invention is not limited to this if the abutment portion is not provided in the first reel holding portion 61.

[0106] Furthermore, in the above embodiment, the second reel holding part 62 can change between the first posture and the second posture, but the second reel holding part 62 can also change to a posture other than the first posture and the second posture. That is, the second reel holding part 62 can at least be displaced to the first posture and the second posture.

[0107] In addition, in the above embodiment, the second reel holding part 62 is directly connected to the first reel holding part 61 in a swingable manner, but the second reel holding part 62 can also be indirectly connected to the first reel holding part 61 in a swingable manner.

[0108] Furthermore, in the above embodiment, the reel holding unit support portion that holds the multiple reel holding units 32 arranged in a parallel direction (parallel direction) includes two support rods (the first support rod 48 and the second support rod 49). However, the support rods only need to include at least one support rod extending in the parallel direction of the multiple component supply units 22. Furthermore, the supported portion (the first engaging portion 73 and the second engaging portion 85 in the above embodiment) of the reel holding unit 32 engages with the support rod from above.

[0109] Provides a reel holding device and a component mounting device that allow the reel to be retrieved at any time, even after it has been assembled, and that makes the reel easy to retrieve.
