[0065] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 The component mounting device 1 in one embodiment of the present invention is shown. The component mounting device 1 repeatedly performs a series of component mounting operations of mounting the component BH on the substrate KB carried in from the upstream process side and discharging it to the downstream process side. In the present embodiment, the left - right direction of the component mounting device 1 as observed by the operator OP is set as the X - axis direction, the front - rear direction of the component mounting device 1 as observed by the operator OP is set as the Y - axis direction. In addition, the up - down direction is set as the Z - axis direction.

[0066] In Figure 1 the component mounting device 1 includes a base 11, a substrate conveying unit 12, a feeder cart 13, a plurality of component supply devices 14, a mounting head 15, and a head moving mechanism 16. The substrate conveying unit 12 conveys the substrate KB in the X - axis direction along a conveyor mechanism extending in the X - axis direction and positions it at a specified working position. The feeder cart 13 is connected to the base 11 by the operator OP walking on the ground. The feeder cart 13 has a feeder base 13B on the upper part. A plurality of slots 13S are provided on the feeder base 13B.

[0067] In Figure 2 the component supply device 14 is configured to include a tape feeder 21 and a reel holding device 22 provided at the rear of the tape feeder 21. As Figure 3 and Figure 4As shown, the reel holding device 22 is configured to include a housing portion 31 that houses a reel 24 around which a carrier tape 23 containing components BH is wound in a longitudinal posture and holds it rotatably, and an accessory 32 that connects the housing portion 31 to the tape feeder 21.

[0068] In Figure 5 , the carrier tape 23 has a base tape 41 and a cover tape 42. On the base tape 41, a plurality of recesses (component housing portions) 33 having an upwardly open shape are provided in a row and at equal intervals in the length direction of the base tape 41. Each of the plurality of recesses 43 houses a component BH, and the cover tape 42 adheres to the base tape 41 so as to cover each recess 43. On the base tape 41, a plurality of engaging holes 44 are provided in a row and at equal intervals in such a manner that the rows of the recesses 43 are arranged in parallel.

[0069] In Figure 5 , the reel 24 has a cylindrical core portion 24b having a diameter smaller than that of the disk portions between a pair of opposed disk portions 24a. A slit 24S for inserting the terminal portion of the carrier tape 23 is formed in the core portion 24b, and the terminal portion of the carrier tape 23 is inserted into the slit 24S. When all of the carrier tape 23 is pulled out from the reel 24, the terminal portion of the carrier tape 23 comes out of the slit 24S of the reel 24 and separates from the reel 24.

[0070] The tape feeder 21 is a device that pulls out the carrier tape 23 from the reel 24 and supplies the components BH. In Figure 2 , the tape feeder 21 is detachably mounted on the feeder base 13B by inserting a socket nut portion 21N provided on the lower surface into a socket 13S. The tape feeder 21 includes a sprocket 52 inside a frame 51 having a tape conveyance path 51L extending in the front-rear direction. The sprocket 52 rotates by engaging outer peripheral teeth (not shown) with the engaging holes 44 of the carrier tape 23, thereby causing the carrier tape 23 to travel within the tape conveyance path 51L.

[0071] A tape insertion port 53 is provided at the rear end portion of the frame 51. The tape insertion port 53 is connected to the tape conveyance path 51L. The carrier tape 23 pulled out from the reel 24 held by the reel holding device 22 is inserted into the tape conveyance path 51L through the tape insertion port 53 via a guide portion 32G provided on the accessory 32 ( Figure 2 ). The carrier tape 23 inserted into the tape conveyance path 51L from the tape insertion port 53 is conveyed at intervals to a component supply position 21K set above the front of the frame 51 by the sprocket 52.

[0072] In Figure 2In this case, before the carrier tape 23 conveyed at intervals by the sprocket wheel 52 reaches the component supply position 21K, the base tape 41 is peeled off from the cover tape 42. When the cover tape 42 is peeled off from the base tape 41, the recess 43 becomes a state of being open upward, and the component BH can be taken out from the recess 43 at the component supply position 21K. The cover tape 42 peeled off from the base tape 41 is sent to the rear part of the frame 51 and recovered.

[0073] The reel 24 held by the reel holding device 22 rotates as the tape feeder 21 pulls the carrier tape 23, and the carrier tape 23 is paid out. Then, when the terminal portion of the carrier tape 23 paid out from the reel 24 comes out of the slit 24S of the reel 24 and the components are nearly used up, the operator OP takes out the reel 24 from the reel holding device 22 and then installs a new reel 24 on the reel holding device 22. Then, the front end portion of the carrier tape 23 pulled out from the new reel 24 installed on the reel holding device 22 is connected (spliced) to the terminal portion of the preceding carrier tape 23.

[0074] In Figure 1 the mounting head 15 has a plurality of nozzles 15N extending downward (also refer to Figure 2 ). Each nozzle 15N can move up and down and rotate about the Z axis with respect to the mounting head 15. By supplying the vacuum pressure supplied through a vacuum pipe (not shown) to each nozzle 15N, the mounting head 15 can generate a vacuum attraction force for adsorbing the component BH at the lower end of each nozzle 15N. The head moving mechanism 16 moves the mounting head 15 inward in the horizontal plane. Thus, the mounting head 15 picks up the component BH supplied by the tape feeder 21 of each component supply device 14 to the component supply position 21K through the nozzle 15N, and repeatedly performs the mounting turning operation of mounting it on the substrate KB positioned at the working position by the substrate conveying unit 12.

[0075] In the component mounting apparatus 1 having such a structure, in the present embodiment, the reel holding device 22 provided in each component supply device 14 has features, and the description thereof will be given below.

[0076] As described above, the reel holding device 22 is configured to include a housing portion 31 and an accessory 32. In Figure 3 , Figure 4 , Figure 6A and Figure 6B the housing portion 31 is configured to include a pair of side plates 61, two connecting shafts 62, a swing support shaft 63, a tape guide 64, and a swing body 65.

[0077] The pair of side plates 61 are arranged opposite to each other in the width direction (X-axis direction) of the tape feeder 21. The side plate 61 has a base portion 61a, a rear lower extending protrusion 61b extending rearward and downward from the base portion 61a, and a rear upper extending protrusion 61c extending rearward and upward from the base portion 61a.

[0078] In Figure 3 and Figure 4 two connecting shafts 62 are arranged vertically between a pair of side plates 61 and connect the bases 61a of the pair of side plates 61 to each other. A swing support shaft 63 is disposed between the pair of side plates 61 and connects the rear lower extending protrusions 61b of the pair of side plates 61 to each other. A belt guide 64 is disposed between the pair of side plates 61 and connects the rear upper extending protrusions 61c of the pair of side plates 61 to each other.

[0079] In Figure 3 , Figure 4 , Figure 6B the swing body 65 has a shape extending along the front-rear direction as a whole. Cylindrical reel abutting portions 65T extending along the width direction (X-axis direction) of the swing body 65 are provided at a portion slightly rearward (toward the operator OP side) of the middle portion of the swing body 65 and at the front end portion, respectively. These two reel abutting portions 65T are in a state of protruding toward the upper surface side of the swing body 65 ( Figure 6B ).

[0080] In Figure 3 , Figure 4 , Figure 6A , Figure 6B , Figure 7A and Figure 7B the reel abutting portion 65T provided at the middle portion of the swing body 65 is pivotally supported by the swing support shaft 63. Accordingly, the swing body 65 is swingable freely in the upper and lower surfaces (in the YZ plane) about the swing support shaft 63.

[0081] In Figure 4 and Figure 6B a portion of the swing body 65 forward of the swing support shaft 63 (on the side opposite to the side toward the operator OP) becomes a reel support portion 65a that supports the outer peripheral edge of the reel 24 housed between the pair of side plates 61 from below. A portion of the swing body 65 rearward of the swing support shaft 63 becomes an extending protrusion 65b extending rearward (i.e., on the side opposite to the reel support portion 65a). The front end portion of the extending protrusion 65b is the rear end portion 65S of the swing body 65 and is located rearward of the rear lower extending protrusion 61b of the pair of side plates 61. Since the reel 24 supported by the swing body 65 has a pair of side plates 61 on its side, movement (tipping) in the out-of-plane direction is prevented.

[0082] The dimension of the swing body 65 in the width direction (X-axis direction) is a dimension slightly larger than the dimension of the supported object reel 24 in the width direction. In addition, the interval between the two side plates 61 is an interval slightly larger than the dimension of the swing body 65 in the width direction.

[0083] InFigure 4 and Figure 6B In Figure 6B , the reel support portion 65a has a downwardly convex arc shape. The radius of curvature of the arc shape of the reel support portion 65a is a value slightly larger than the radius of curvature of the outer peripheral edge of the reel 24 supported by the reel support portion 65a. The reel 24 is supported by the reel support portion 65a by bringing the outer peripheral edge into contact with two reel contact portions 65T formed on the reel support portion 65a from above. A swing stopper 66 protruding laterally of the swing body 65 is provided at the middle portion in the front-rear direction of the swing body 65.

[0084] In the swing range in the upper and lower planes with the swing support shaft 63 of the swing body 65 as a fulcrum, the downward swing of the front end side of the swing body 65 is restricted to the position where the reel contact portion 65 located on the front end portion side of the swing body 65 contacts a part of the accessory 32 (specifically, the rear surface of the lifting base 75 described later) from the rear upper side ( Figure 6B ), hereinafter referred to as the "first position". Figure 3 , Figure 6B and Figure 7A the position shown). On the other hand, the downward swing of the rear end side of the swing body 65 is restricted to the position where the swing stopper 66 provided on the swing body 65 contacts the swing stopper contact portion 61T provided on the lower edge side of each of the pair of side plates 61 (hereinafter referred to as the "second position". Figure 7B the position shown).

[0085] In Figure 4 and Figure 6B , a coil spring 67 is assembled to the swing support shaft 63. The coil spring 67 functions as a biasing mechanism that biases the swing body 65 toward the first position. Therefore, in a state where no external force (such as a force for pressing the rear end portion 65S of the swing body 65 downward as described later) acts on the swing body 65, the swing body 65 is located at the first position by the acting force of the coil spring 67.

[0086] When the rear end portion 65S (the front end portion of the extension protrusion 65b) of the swing body 65, which is one end portion, is pressed downward ( Figure 7A the arrow P shown in Figure 7A ), the swing body 65 overcomes the acting force of the coil spring 67 and swings about the swing support shaft 63 in the direction in which the rear end portion 65S moves downward ( Figure 7A → Figure 7B ). Then, when the swing stopper 66 contacts the swing stopper contact portion 61T, the swing body 65 is located at the second position ( Figure 7B ). When the hand is released from the extension protrusion 65b in a state where the swing body 65 is located at the second position, the swing body 65 swings toward the first position side by the acting force of the coil spring 67 ( Figure 7B → Figure 7A), when the front end portion of the end portion on the other end side of the swing body 65 abuts against the swing body abutting portion 32T of the accessory 32, it is located at the first position ( Figure 7A ).

[0087] The tape guide 64 is a shaft-like member extending along the width direction (X-axis direction) of the swing body 65. As Figure 3 , Figure 4 , Figure 6A and Figure 6B show, it is located above the rear end portion 65S (the front end portion of the extending projection 65b) of the swing body 65. The area between the rear end portion 65S of the swing body 65 and the tape guide 64 is the movement path of the reel 24 relative to the housing portion 31, and is the passage of the carrier tape 23 pulled out from the reel 24 supported by the reel support portion 65a, that is, the opening 68 ( Figure 3 , Figure 6B , Figure 7A and Figure 7B ). Therefore, when the reel 24 is housed in the housing portion 31, and when the reel 24 is taken out from the housing portion 31, the reel 24 moves through the opening 68, and the carrier tape 23 pulled out from the carrier tape 23 supported by the reel support portion 65a passes through the opening 68 and is conveyed to the tape feeder 21 ( Figure 7A ).

[0088] Here, the distance between the rear end portion 65S of the swing body 65 and the tape guide 64 (hereinafter referred to as "opening diameter TK". Figure 8A , Figure 8B ) varies depending on the swing position of the swing body 65. Specifically, in the state where the swing body 65 is located at the first position ( Figure 8A ), in the state where the opening diameter TK is smaller than the diameter DR of the reel and the swing body 65 is located at the second position ( Figure 8B ), the opening diameter TK becomes larger than the diameter DR of the reel 24.

[0089] Therefore, in the state where the swing body 65 is located at the first position, the movement of the reel 24 through the opening 68 cannot be performed, but in the state where the swing body 65 is located at the second position, the movement of the reel 24 through the opening 68 can be performed. Thus, in the state where the swing body 65 is located at the first position, the reel 24 cannot be housed in the housing portion 31, or the reel 24 housed in the housing portion 31 cannot be taken out from the housing portion 31. However, by making the swing body 65 located at the second position ( Figure 7A → Figure 7B ), it becomes possible to house the reel 24 in the housing portion 31, or to take out the reel 24 housed in the housing portion 31 from the housing portion 31 ( Figure 7B the arrow A shown in).

[0090] Thus, in the present embodiment, in a state where the swing body 65 is in the first position, since the opening diameter TK, which is the distance between the rear end portion 65S of the swing body 65 and the tape guide 64, is smaller than the diameter DR of the reel 24, the reel 24 cannot pass through the opening 68. In a state where the swing body 65 is in the second position, since the opening diameter TK is larger than the diameter DR of the reel 24, the reel 24 can pass through the opening 68.

[0091] In Figure 3 , Figure 4 , Figure 9A and Figure 9B , the accessory 32 includes a connection portion 71, a fixed arm 72, a fixed base 73, a lifting arm 74, a lifting base 75, and a fixing mechanism 76. The connection portion 71 is connected to the rear portion of the tape feeder 21 by a plurality of connection screws 71S. The fixed arm 72 is provided to extend downward from the connection portion 71. The fixed base 73 is provided at the lower end of the fixed arm 72 and has a shape extending in the vertical direction.

[0092] In Figure 3 and Figure 4 , the lifting arm 74 is a plate-like member extending in the vertical direction, and the lifting base 75 is a member extending in the vertical direction. The lifting arm 74 is slidable relative to the fixed base 73 in the vertical direction, and the lifting base 75 is slidable relative to the lifting arm 74 in the vertical direction.

[0093] As Figure 4 and Figure 6A , Figure 6B shown, the housing portion 31 is mounted on the lifting base 75 via a connection shaft 62 connecting the upper and lower sides of a pair of side plates 61 (also refer to Figure 4 ). On the rear surface of the lifting base 75, there is formed the above-described swing body abutting portion 32T against which the reel abutting portion 65T on the front end portion side of the swing body 65 abuts ( Figure 6B , Figure 7A and Figure 7B ).

[0094] In Figure 6B , Figure 9A and Figure 9B , locking portions (an upper locking portion 74a and a lower locking portion 74b) that bend and extend in the outward direction (X-axis direction) are provided at the upper end portion and the lower end portion of the lifting arm 74, respectively. The upper locking portion 74a protrudes into a region above the upper end of the lifting base 75, thereby restricting the upper end of the lifting base 75 from being located above the upper end of the lifting arm 74. The lower locking portion 74b protrudes into a region below the lower end of the fixed base 73, thereby restricting the lower end of the lifting arm 74 from being located at a position above the lower end of the fixed base 73.

[0095] In Figure 9AAnd Figure 9B In Figure 9B , a fixing base inner stopper 73S is provided at the lower part inside the fixing base 73 for the upper engaging portion 74a of the lifting arm 74 to abut from above. The fixing base inner stopper 73S restricts the movement of the lifting arm 74 to a position lower than the position where the upper engaging portion 74a of the lifting arm 74 abuts from above.

[0096] In addition, a lifting base inner stopper 75S is provided at the upper part inside the lifting base 75 for abutting from above against the lower engaging portion 74b of the lifting arm 74. The lifting base inner stopper 75S restricts the movement of the lifting base 75 to a position lower than the position where it abuts from above against the lower engaging portion 74b of the lifting arm 74.

[0097] In Figure 3 , Figure 4 And Figure 6B In Figure 3 , Figure 4 , and Figure 6B , the accommodating portion 31 is located behind the lifting base 75 and is mounted on the lifting base 75 via the aforementioned upper and lower connecting shafts 62. Specifically, the upper and lower connecting shafts 62 of the accommodating portion 31 penetrate the lifting base 75 horizontally ( Figure 6A And Figure 10A ), whereby the accommodating portion 31 and the lifting base 75 move integrally in the vertical direction. In addition, Figure 10A (And the following Figure 10A And Figure 10B ) is an enlarged view of the area AR in Figure 6A .

[0098] Here, as shown in Figure 10A , the interval X1 between the pair of side plates 61 is larger than the width direction dimension X2 of the lifting base 75. Therefore, the accommodating portion 31 can move the difference amount ΔX (=X1 - X2) in the width direction (X-axis direction) of the reel 24 with respect to the lifting base 75 (i.e., with respect to the tape feeder 21). Figure 10B Shows the state where the accommodating portion 31 is moved to the right with respect to the lifting base 75, Figure 10C Shows the state where the accommodating portion 31 is moved to the left with respect to the lifting base 75.

[0099] Thus, in the reel holding device 22 of the present embodiment, the accommodating portion 31 is movable freely in the width direction of the reel 24 held by the reel holding device 22 with respect to the accessory 32 connected to the tape feeder 21.

[0100] The fixing mechanism 76 is a device for fixing the lifting base 75 to the fixing base 73 and is provided on the lifting base 75. As shown in Figure 3 , Figure 4 And Figure 6BAs shown, the fixing mechanism 76 has a locking member 81 and a biasing spring 82. The locking member 81 is slidably disposed in the lifting base 75 in the Y-axis direction. The biasing spring 82 is disposed in the lifting base 75 and biases the locking member 81 toward the fixed base 73. The locking member 81 has a wedge portion 81K that protrudes toward the fixed base 73 side.

[0101] As Figure 6B shown, a window portion 75W that opens laterally is provided in the lifting base 75. An operation portion 81B that protrudes laterally of the lifting base 75 is formed on a side surface of the locking member 81. The operation portion 81B protrudes from the window portion 75W to the side of the lifting base 75, and an operator OP can slide and operate the locking member 81 in the Y-axis direction by operating the operation portion 81B.

[0102] When the operator OP operates the locking member 81 rearward (i.e., the side away from the fixed base 73) by overcoming the biasing force of the biasing spring 82 with a finger ( Figure 11A arrow B1 shown in), the wedge portion 81K retracts into the lifting base 75. Thereby, the wedge portion 81K disengages from the cutout portion 73 of the fixed base 73, and the fixing of the lifting base 75 relative to the fixed base 73 is released ( Figure 11A ).

[0103] On the other hand, as described above, according to the state where the wedge portion 81K disengages from the cutout portion 73K, when the operator OP releases the finger from the locking member 81, the locking member 81 moves forward (i.e., the side closer to the fixed base 73) under the biasing force of the biasing spring 82 ( Figure 11B arrow B2 shown in), and the wedge portion 81K is inserted into the cutout portion 73K of the fixed base 73. Thereby, the lifting base 75 becomes a state fixed relative to the fixed base 73 ( Figure 11B ).

[0104] In addition, when the lifting base 75 rises from a state below the fixed base 73 and is located laterally of the fixed base 73, during this process, a tapered portion 81T of the wedge portion 81K formed on the locking member 81 abuts the fixed base 73 from below ( Figure 12A ). Therefore, the locking member 81 automatically retracts into the lifting base 75 by overcoming the biasing force of the biasing spring 82 ( Figure 12A → Figure 12B ), and when the lower end of the tapered portion 81T reaches the lower edge 73F of the cutout portion 73K ( Figure 12B ), it is inserted into the cutout portion 73K by the biasing force of the spring member 82 ( Figure 12B → Figure 12C ).

[0105] With the wedge portion 81K of the locking member 81 inserted into the notch portion 73K of the fixed base 73, the lifting base 75 is located laterally of the fixed base 73( Figure 6B , Figure 9A and Figure 13A ), and the lifting arm 74 is in a state of being housed between the fixed base 73 and the lifting base 75. Hereinafter, the position of the housing portion 31 when it is located laterally of the fixed base 73 will be referred to as the "upper position".

[0106] According to the state where the housing portion 31 is in the upper position, if the operator OP operates the operation portion 81B of the locking member 81 of the fixing mechanism 76 and disengages the wedge portion 81K of the locking member 81 from the notch portion 73K of the fixed base 73( Figure 11A the arrow B1 shown in Figure 11A ), the fixing of the lifting base 75 to the fixed base 73 is released(

[0107] ). Thereby, the housing portion 31 can descend relative to the fixed base 73 together with the lifting base 75 under the action of its own weight. Figure 13B If the operator OP releases the fixing of the lifting base 75 to the fixed base 73 while holding the housing portion 31 by hand and slowly lowers the housing portion 31, the lifting arm 74 descends together with the lifting base 75 in a state where the upper locking portion 74a abuts against the upper end of the lifting base 75. Then, when the upper locking portion 74a of the lifting arm 74 abuts against the fixed base inner stopper 73S from above(

[0108] ), the lifting arm 74 can no longer descend further, and then the lifting base 75 descends together with the housing portion 31. Figure 9B and Figure 13C )

[0109] In this way, in the present embodiment, the fixed base 73, the lifting arm 74, and the lifting base 75 of the accessory 32 constitute a lifting mechanism 77 that lifts the housing portion 31 relative to the tape feeder 21( Figure 13A ). That is, in the present embodiment, the accessory 32 has a structure including a lifting mechanism 77 that lifts the housing portion 31. Moreover, the lifting mechanism 77 positions the housing portion 31 at one of a position above the tape feeder 21 and a lower position below the upper position.

[0110] As Figure 14AAs shown, the spool 24 that supports the outer peripheral edge of the disk portion 24a by the swing body 65 located at the first position is in a state where its central position (i.e., the position of the center of gravity GV) is between the two spool contact portions 65T that support the outer peripheral edge of the spool 24. In this state, the spool 24 is stably supported by the swing body 65. Even when the carrier tape 23 pulled out rearward from the spool 24 is pulled, the spool 24 rotates on the spot while pulling out the carrier tape 23. Therefore, when the spool 24 is in use, the swing body 65 is located at the first position, and the spool 24 is supported by the swing body 65 located at the first position. Hereinafter, the position of the spool 24 supported by the swing body 65 located at the first position is referred to as the "use position".

[0111] The carrier tape 23 pulled out rearward from the spool 24 located at the use position is pulled upward and forward after passing between the rear end portion 65S of the swing body 65 and the tape guide 64, that is, after the opening 68 of the carrier tape 23, and is inserted into the tape insertion port 53 of the tape feeder 21 ( Figure 2 ). The tape feeder 21 into which the carrier tape 23 is inserted through the tape insertion port 53 guides and conveys the carrier tape 23 into the interior of the frame 51 through the sprocket 52. At this time, the carrier tape 23 pulled out from the spool 24 through the opening 68 abuts the lower surface side against the tape guide 64, is guided by the tape guide 64, and is introduced into the tape feeder 21.

[0112] When the carrier tape 23 pulled out from the spool 24 located at the use position is introduced into the tape feeder 21, the spool 24 is pulled rearward by the tension of the carrier tape 23, rotates on the spool support portion 65a of the swing body 65, and discharges the carrier tape 23 rearward. Moreover, when the terminal portion of the carrier tape 23 with the components nearly used up comes out of the slit 24S of the spool core portion 24b of the spool 24, the terminal portion of the carrier tape 23 is hooked on the slit 24S, so the spool 24 is strongly pulled rearward by the carrier tape 23.

[0113] At this time, although there is a case where the spool 24 moves toward the extended projection portion 65b side from the spool support portion 65a ( Figure 14A → Figure 14B ), in the state where the swing body 65 is located at the first position, the opening diameter TK is smaller than the diameter DR of the spool 24 ( Figure 8A ), so the spool 24 prevents its upper part from abutting against the tape guide 64 and further moving rearward. Therefore, the spool 24 cannot pass through the opening 68 ( Figure 14B ), and it is prevented that the spool 24 falls off from the housing portion 31.

[0114] On the other hand, when taking out the spool 24 located at the use position, the operator OP presses the rear end portion 65S (the front end portion of the extended projection portion 65b) of the swing body 65 downward ( Figure 7A the arrow P shown in), causes the swing body 65 to swing around the swing support shaft 63, and is located at the second position (Figure 7B )。During this process, the reel 24 is lifted by the reel support portion 65a of the swing body 65 and moves rearward (i.e., toward the opening 68 side), and the reel 24 moves toward the opening 68 side. Additionally, at the same time, the rear end portion 65S of the swing body 65 relatively descends with respect to the tape guide 64, and the opening diameter TK becomes larger than the diameter DR of the reel 24. Therefore, the operator OP can take out the reel 24 from the inside of the housing portion 31 through the opening 68. Additionally, the operator OP can also insert the reel 24 through the opening 68 and house it inside the housing portion 31 (within the area between the pair of side plates 61).

[0115] In this way, in the reel holding device 22 of the present embodiment, the housing portion 31 that houses the reel 24 around which the carrier tape 23 storing the component BH is wound in a longitudinal posture includes the swing body 65 that supports the outer periphery of the reel 24 from below, and the tape guide 64 provided above one end portion, i.e., the rear end portion 65S, of the swing body 65. An opening 68 that also serves as a movement path for the reel 24 and a passage for the carrier tape 23 pulled out from the reel 24 is formed between the rear end portion 65S of the swing body 65 and the tape guide 64. The swing body 65 is swingable between a first position where the reel 24 supported because the distance between its rear end portion 65S and the tape guide 64, i.e., the opening diameter TK, is smaller than the diameter DR of the reel 24 cannot pass through the opening 68, and a second position where the reel 24 supported because the opening diameter TK is larger than the diameter DR of the reel 24 can pass through the opening 68.

[0116] Therefore, when using the reel 24 with the swing body 65 in the first position, even if the reel 24 is pulled by the carrier tape 23, the reel 24 will not fall off from the housing portion 31. However, if the swing body 65 is swung to the second position, the reel 24 can be moved in and out with respect to the housing portion 31. Therefore, it is possible to reliably prevent the reel 24 from falling off during use and to easily perform the replacement operation of the reel 24. Thus, according to the reel holding device 22 of the present embodiment, it is possible to achieve both preventing the reel 24 from falling off during use and facilitating the replacement operation of the reel 24.

[0117] Figure 15 and Figure 16 Indicates that two adjacent tape feeders 21 and two reel holding devices 22 mounted on these two tape feeders 21 are used as the component supply system 90. Figure 15 An example is shown in the case where the housing portion 31 of the reel holding device 22 mounted on the tape feeder 21 on the right side is in the upper position and the housing portion 31 of the reel holding device 22 mounted on the tape feeder 21 on the left side is in the lower position. Figure 16An example is shown where the housing portion 31 of the reel holding device 22 installed on the tape feeder 21 on the right side is positioned below, and the housing portion 31 of the reel holding device 22 installed on the tape feeder 21 on the left side is positioned above.

[0118] Figure 15 Or Figure 16 The component supply system 90 shown is configured to include a first tape feeder (the tape feeder 21 disposed on the right side or the left side) that pulls out the carrier tape 23 from the first reel (the reel 24 on the right side or the left side) and supplies the component BH to the component mounting device 1, a second tape feeder (the tape feeder 21 disposed on the left side or the right side) that is disposed adjacent to the first tape feeder and pulls out the carrier tape 23 from the second reel (the reel 24 on the left side or the right side) and supplies the component BH to the component mounting device 1, a first reel holding device (the reel holding device 22 on the right side or the left side) that is mounted on the first tape feeder via the first accessory (the accessory 32 on the right side or the left side) and holds the first reel, and a second reel holding device (the reel holding device 22 on the left side or the right side) that is mounted on the second tape feeder via the second accessory (the accessory 32 on the left side or the right side) and holds the second reel. Further, the first reel holding device has a first housing portion (the housing portion 31 on the right side or the left side) that is mounted on the first accessory and houses the first reel, the second reel holding device has a second housing portion (the housing portion 31 on the left side or the right side) that is mounted on the second accessory and houses the second reel, the first housing portion is configured to be located below the second housing portion, the first housing portion is movable in the width direction of the first reel relative to the first accessory, and the second housing portion is configured to be movable in the width direction of the second reel relative to the second accessory.

[0119] In the component supply system 90 thus constituted by the two tape feeders 21 and the two reel holding devices 22, if one side's housing portion 31 is in the "upper position" and the other side's housing portion 31 is in the "lower position", the dimension in the width direction of the housing portion 31 is larger than the dimension in the width direction of the tape feeder 21. As Figure 17 shown, even if the housing portion 31 of the reel holding device 22 extends from the lateral dimension of the tape feeder 21 on which the reel holding device 22 is installed, the housing portions 31 do not interfere with each other in the two adjacent reel holding devices 22. Therefore, the two tape feeders 21 of the reel holding device 22 having a dimension in the width direction of the housing portion 31 larger than the dimension in the width direction of the tape feeder 21 can be disposed adjacent to each other (i.e., close to the slot 13S) on the feeder base 13B.

[0120] In addition, as Figure 17As shown, even if the housing part 31 projects outward from the width dimensions WD of the two tape feeders 21 that constitute a component supply system 90 respectively, as long as the same component supply systems 90 are arranged in the X-axis direction, the housing parts 31 can be made not to interfere with each other, and a plurality of component supply systems 90 can be arranged adjacent to each other (close to the slot 13S) on the feeder base 13B ( Figure 18 ).

[0121] Here, as shown by the single-dot chain line in Figure 19 , in the case where a tape feeder (referred to as "adjacent feeder 21A") with a reel holding device (referred to as "large-size reel holding device 22A") having a size that straddles the housing part 31 at the upper position and the housing part 31 at the lower position is provided adjacent to the above-mentioned component supply system 90, there is a concern that the housing part 31 projecting outward may interfere with the large-size reel holding device 22A of the adjacent feeder 21A. In this case, the housing part 31 at the upper position and the housing part 31 at the lower position are respectively moved inward (toward the side where they approach each other) ( Figure 20 the arrow C shown in Figure 20 ), and after the two upper and lower housing parts 31 are respectively converged within the width dimension WD of the two tape feeders 21 (

[0122] ), the adjacent feeder 21A is provided. Figure 21 In this way, the housing part 31 does not interfere with the large-size reel holding device 22A of the adjacent feeder 21A ( Figure 21

[0123] ), so that even when an adjacent feeder 21A having a reel holding device different in type from the reel holding device 22 is arranged adjacent to the component supply system 90, it can be arranged in such a manner that the adjacent feeder 21A is close to the component supply system 90 (without leaving a space for the slot 13S). Therefore, the slots 13S formed according to the intervals of the thin slots 13S can be effectively utilized, and the area productivity can be improved.

[0123] Thus, in the reel holding device 22 in the present embodiment, the housing portion 31 that houses the reel 24 in a longitudinal posture can move in the width direction (X-axis direction) of the housed reel 24 with respect to the attachment 32 that connects the housing portion 31 to the tape feeder 21. Therefore, even when the width direction dimension of the reel holding device 22 is larger than the width direction dimension of the tape feeder 21, interference between the housing portions 31 can be avoided by laterally moving the housing portion 31 with respect to the attachment 32. Further, thereby, when configuring the component supply system 90 composed of two tape feeders 21 and two reel holding devices 22, the two reel holding devices 22 can be prevented from protruding outward from the width direction dimension WD of the two tape feeders 21. Thus, a plurality of component supply systems 90 can be arranged adjacent to each other (with reduced intervals), and tape feeders having different types of reel holding devices can also be arranged adjacent to each other (with reduced intervals). Therefore, the area productivity can be improved.

[0124] As described above, in the reel holding device 22 in the present embodiment, when using the reel 24, the swing body 65 is positioned at the first position, preventing the reel 24 from passing through the opening 68 and thus preventing the reel 24 from falling off the housing portion 31. On the other hand, by positioning the swing body 65 at the second position, the reel 24 can pass through the opening 68, facilitating the replacement of the reel 24. Therefore, according to the reel holding device 22 in the present embodiment, it is possible to achieve both preventing the reel 24 from falling off during use of the reel 24 and facilitating the replacement operation of the reel 24.

[0125] So far, the embodiments of the present invention have been described, but the present invention is not limited to the above-described embodiments and can be variously modified. For example, in the above-described embodiment, although the housing portion 31 is configured to have a pair of side plates 61, it is not necessarily required to have the side plates 61 as long as the movement (tipping) of the reel 24 supported by the swing body 65 in the out-of-plane direction can be prevented. Alternatively, a flange portion having a function equivalent to that of the pair of side plates 61 may be provided on the swing body 65 instead of providing the pair of side plates 61.
