[0040] (Embodiment 1)

[0041] Figure 1 A component mounting device 1 including a tape feeder as a component supply device according to Embodiment 1 of the present invention is shown. The component mounting device 1 is a device for mounting components BH on a substrate KB, and includes a substrate transfer unit 12 on a base 11. The substrate transfer unit 12 transfers the substrate KB in the horizontal direction and positions it at a predetermined working position. Hereinafter, for ease of explanation, the transfer direction of the substrate KB by the substrate transfer unit 12 is defined as the X direction, the horizontal direction orthogonal to the X direction is defined as the Y direction, and the vertical direction is defined as the Z direction. In addition, the direction toward the center side of the base 11 in the Y direction is referred to as "front", and the direction toward the opposite side is referred to as "rear".

[0042] A mounting head 13 is provided above the base 11. The mounting head 13 moves in the horizontal direction by a head moving mechanism (not shown). The mounting head 13 has a plurality of component holding suction nozzles 14 extending downward.

[0043] In Figure 1 , a carriage 15 is connected to an end portion of the base 11 in the Y direction. The carriage 15 includes a feeder base 21 and a reel holding portion 22. A plurality of tape feeders 16 are arranged and assembled along the X direction on the feeder base 21.

[0044] In Figure 2In (a) and (b) thereof, the feeder base 21 has a block-shaped table portion 31 and a wall portion 32 provided at the front of the table portion 31 and extending upward. The upper surface of the table portion 31 serves as the feeder support portion 33, and the rear surface of the table portion 31 serves as the feeder connection surface 34.

[0045] Assembly slots 35 for assembling the tape feeder 16 are arranged in the X direction on the table portion 31. As Figure 2 shown in (a) thereof, one assembly slot 35 is composed of a pair of feeder guide portions 41 arranged in the X direction on the feeder support portion 33, through holes that penetrate the wall portion 32 in the thickness direction (Y direction), i.e., upper and lower two positioning holes 42, an assembly hole 44 provided on the feeder connection surface 34, an electrical socket 45, and an air socket 46. Thus, in Embodiment 1, the feeder base 21 has a plurality of assembly slots 35 arranged in the X direction.

[0046] The feeder guide portions 41 are composed of rail-shaped members arranged in the lateral direction (X direction, the direction intersecting the conveying direction of the carrier tape in the horizontal plane) and extending in the front-rear direction (Y direction). The upper and lower two positioning holes 42 are arranged in the Z direction. The assembly hole 44, the electrical socket 45, and the air socket 46 are arranged in the Z direction, and the assembly hole 44 is located above the electrical socket 45. The air socket 46 is located between the assembly hole 44 and the electrical socket 45.

[0047] The reel holding portion 22 rotatably holds a reel RL around which a carrier tape CT to be conveyed by the tape feeder 16 is wound. As Figure 3 shown in (a) and (b) thereof, a plurality of component storage grooves PK are arranged in a row on the carrier tape CT, and a plurality of feed holes KH are arranged in a row at a position parallel to the row of the component storage grooves PK.

[0048] In Figure 3 (a) and (b) thereof, one component BH is stored in each of the component storage grooves PK, and a cover tape TT is pasted at a position covering the component storage grooves PK on the upper surface of the carrier tape CT. That is, the component BH is stored in the carrier tape CT in a state of being covered by the cover tape TT.

[0049] As Figure 3 shown in (a) and (b) thereof or Figure 4 shown in (a) and (b) thereof, the cover tape TT has a leading portion SD extending from the front end ST of the carrier tape CT. The leading portion SD can be in a form in which the front end portion of the cover tape TT protrudes from the front end ST of the carrier tape CT as shown in (a) and (b) thereof, or can be in a form in which a part of an auxiliary tape HJ pasted on the cover tape TT protrudes from the front end ST of the carrier tape CT as shown in (a) and (b) thereof. Figure 3 (a) and (b) thereof, or can be in a form in which a part of an auxiliary tape HJ pasted on the cover tape TT protrudes from the front end ST of the carrier tape CT as shown in (a) and (b) thereof. Figure 4 (a) and (b) thereof.

[0050] In the case of a configuration in which the front end of the cover tape TT protrudes from the front end ST of the carrier tape CT, the leading portion SD is composed of a portion of the cover tape TT (the portion having a length L) extending from the front end ST of the carrier tape CT. Figure 3 (a)). In the case of using the auxiliary tape HJ, the leading portion SD is composed of a portion (the portion with a length L) of the auxiliary tape HJ extending from the front end ST of the carrier tape CT ( Figure 4 (b)).

[0051] exist Figure 5 (a), (b) and Figure 6 In the embodiment, the tape feeder 16 includes a main body 51 detachably mounted in the mounting slot 35 of the feeder base 21. Two positioning pins 52 protruding forward are provided at the front end of the main body 51.

[0052] exist Figure 5 (a), (b) and Figure 6 In the embodiment, a downward extending portion 53 extending downward is formed at the rear of the main body 51 of the tape feeder 16. A fixed portion 54, a connector 55, and an air connection portion 56 are provided on the front surface side of the downward extending portion 53 so as to protrude forward.

[0053] When the tape feeder 16 is mounted in the mounting slot 35, the engaged portion 51K ( Figure 6 ) is inserted between the feeder guides 41 constituting the assembly slot 35 ( Figure 2 (a) → Figure 2 (b)). Thus, the two positioning pins 52 are inserted into the upper and lower positioning holes 42, and the fixed portion 54 is fitted into the assembly hole 44. In addition, the connector 55 is connected to the electric socket 45, and the air connection portion 56 is connected to the air socket 46.

[0054] When the fixed portion 54 is fitted into the mounting hole 44, the fixed portion 54 is connected to a fixing portion (not shown) provided inside the table portion 31, and the tape feeder 16 is fixed to the table portion 31. When the connector 55 is connected to the electrical socket 45, the tape feeder 16 is electrically connected and connected for signal transmission with the table portion 31. When the air connection portion 56 is connected to the air socket 46, air can be supplied from the base 11 side to the tape feeder 16 side through the table portion 31.

[0055] exist Figure 6 In the embodiment, a conveying path 61 for conveying the carrier tape CT is provided in the main body 51. The conveying path 61 has a carrier tape introduction port 61A at the rear end of the main body 51 and a carrier tape discharge port 61B at the front end of the main body 51. The upper surface of the conveying path 61 is a conveying surface 61M (see FIG. 6A ) for supporting and conveying the lower surface of the carrier tape CT. Figure 8). That is, in Embodiment 1, the conveyance path 61 has a conveyance surface 61M that supports the carrier tape CT from below.

[0056] In Figure 6 , a carrier tape conveyance unit 62 for conveying the carrier tape CT is provided at the upper front side within the main body portion 51. The carrier tape conveyance unit 62 includes three sprockets (a lead-in sprocket 62A, a positioning sprocket 62B, and a discharge sprocket 62C) arranged in order from the rear to the front and a sprocket drive motor 62D.

[0057] In Figure 6 , a plurality of feed pins 62P are provided on the outer circumferential portions of the lead-in sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C, respectively. These three sprockets rotate in the same direction via a gear mechanism (not shown) by the sprocket drive motor 62D. The direction in which the three sprockets rotate is the direction in which the feed pin 62P located at the highest position of each sprocket moves forward. The operation of the sprocket drive motor 62D is controlled by a control unit 63 provided within the main body portion 51 ( Figure 6 ).

[0058] The carrier tape CT is pulled out from the reel RL, and its front end side (the side where the aforementioned leading portion SD is formed) is inserted into the conveyance path 61 through the carrier tape inlet 61A. The carrier tape CT inserted into the conveyance path 61 is conveyed forward (downstream side) by the above three sprockets (the lead-in sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C), that is, the carrier tape conveyance unit 62. At this time, the carrier tape CT is transferred in the order of the lead-in sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C.

[0059] The carrier tape CT inserted through the carrier tape inlet 61A is conveyed toward the downstream side, that is, the carrier tape outlet 61B, by the carrier tape conveyance unit 62. The carrier tape CT conveyed toward the downstream side is peeled off the cover tape TT before passing through the component extraction opening 16K provided in the upper front portion of the main body portion 51. At the time of passing through the component extraction opening 16K, the component BH accommodated in the carrier tape CT in a state covered by the cover tape TT becomes exposed.

[0060] The component extraction opening 16K is provided between the positioning sprocket 62B and the discharge sprocket 62C, and the exposed component BH is intermittently located at the component extraction position 16T set inside the component extraction opening 16K in sequence. Thus, the mounting head 13 can adsorb and hold the component BH located at the component extraction opening 16K (component extraction position 16T) by the component holding suction nozzle 14 and take it out (pick up) from the tape feeder 16. In this way, the carrier tape conveyance unit 62 conveys the carrier tape CT along the conveyance path 61 with the leading portion SD of the cover tape TT leading, and positions the component BH at the component extraction position 16T.

[0061] In Figure 6In [description], the aforementioned air connection portion 56 provided in the lower extension portion 53 of the main body portion 51 is connected to an air ejection portion 65 provided in the upper front portion within the main body portion 51 through an air tube 64 provided within the lower extension portion 53. An air ejection control valve 66 provided within the lower extension portion 53 is interposed in the air tube 64.

[0062] When the tape feeder 16 is assembled to the feeder base 21, the air connection portion 56 is connected to the air socket 46 on the feeder base 21 side. In a state where the air connection portion 56 is connected to the air socket 46, by controlling the air ejection control valve 66 by the control unit 63, the air supplied from the feeder base 21 side through the air tube 64 can be ejected from the air ejection portion 65.

[0063] In Figure 6 [description], a [hood] 70 is provided in the upper front portion of the main body portion 51. Specifically, as Figure 7 and Figure 8 and Figure 9 show, it is provided so as to cover from above a portion between the positioning sprocket 62B and the discharge sprocket 62C in the conveyance path 61. The hood 70 is constituted by a single plate-like member in Embodiment 1 and is detachable from and attachable to the main body portion 51.

[0064] Figure 10 shows a state where the hood 70 is attached to the main body portion 51. As can be seen from Figure 10 [description], the main body portion 51 of the tape feeder 16 includes two carrier tape support portions 51S that extend and expand along the YZ plane and face each other in the X direction. And, the upper edges of the carrier tape support portions 51S form the conveyance surface 61M.

[0065] As Figure 10 shows, the hood 70 is provided in the upper front portions of the two carrier tape support portions 51S so as to cover from above a part of the upper edges (i.e., the conveyance surface 61M) of the two carrier tape support portions 51S. As described above, the conveyance surface 61M is constituted by the upper edges of the two carrier tape support portions 51S, and both end portions of the carrier tape CT are supported from below by the upper edges of the two carrier tape support portions 51S. Therefore, the carrier tape CT can be used not only for a type (so-called paper tape type) having no portion protruding downward but also for an embossed type having an embossed portion protruding downward.

[0066] In Figure 7 and Figure 10In this case, the tape cover 70 includes a first tape pressing portion 71 that forms the central portion thereof, a second tape pressing portion 72 that forms a portion on the upstream side of the first tape pressing portion 71, and a third tape pressing portion 73 that forms a portion on the downstream side of the first tape pressing portion 71. The first tape pressing portion 71 and the second tape pressing portion 72 are connected by a connecting portion 74. A cover tape passage 75 formed by a gap between the first tape pressing portion 71 and the second tape pressing portion 72 is formed on the side of the connecting portion 74 (the side in the width direction of the tape cover 70, that is, the side in the X direction). The above-described component removal opening 16K is formed in the third tape pressing portion 73 ( Figure 7 ).

[0067] In this way, in Embodiment 1, the tape cover 70 is configured to cover the upper surface of the carrier tape CT carried by the carrier tape conveying portion 62, and has a component removal opening 16K formed at the component removal position 16T and a cover tape passage 75 formed by a gap formed at a position upstream and away from the component removal opening 16K.

[0068] In Figure 7 a protruding piece 71H protruding upstream is formed at the upstream end of the first tape pressing portion 71, and the edge of the protruding piece 71H (that is, the upstream edge of the first tape pressing portion 71) serves as a stopper portion 76. As will be described later, the stopper portion 76 functions as a part of a guiding portion 140 ( Figure 8 ) that blocks the advancement of the leading portion SD of the cover tape TT included in the carrier tape CT conveyed by the carrier tape conveying portion 62 and guides the leading portion SD upward (to the upper surface side of the tape cover 70) from the cover tape passage 75.

[0069] As described above, the second tape pressing portion 72 is connected to the upstream side of the first tape pressing portion 71 by the connecting portion 74. The downstream end of the second tape pressing portion 72 has a linear shape extending in the X direction, and is disposed opposite to the stopper portion 76 with a predetermined gap (cover tape passage 75) therebetween on the upstream side of the upstream edge of the first tape pressing portion 71, that is, the stopper portion 76.

[0070] In Figure 11 the downstream portion of the second tape pressing portion 72 becomes a contact portion 77 that extends parallel to the conveying surface 61M above the conveying surface 61M. In addition, the portion upstream of the contact portion 77 becomes an inclined portion 78 whose height from the conveying surface 61M gradually increases upstream. The lower surface of the inclined portion 78 is a conical surface 78M whose distance from the conveying surface 61M becomes narrower from upstream to downstream.

[0071] In Figure 11In the state where the carrier tape CT is not inserted into the conveyance path 61, the lower surface of the second tape pressing portion 72 does not contact the conveyance surface 61M, and a gap GP in size is formed between the lower surface of the second tape pressing portion 72 and the conveyance surface 61M. Moreover, the size GP of this gap is a size that is larger than the thickness of the cover tape TT but smaller than the thickness of the carrier tape CT.

[0072] In Figure 7 In, both end portions in the width direction (X direction) of the third tape pressing portion 73 become bent portions 79 that are bent downward. Since the third tape pressing portion 73 is formed with the bent portions 79 at both end portions in the width direction in this way, the bending rigidity in the vertical direction becomes high and it is difficult to flex, whereby the carrier tape CT near the component take-out opening 16K can be firmly pressed against the conveyance surface 61M. On the other hand, the first tape pressing portion 71 connected to the upstream side of the third tape pressing portion 73 and further the second tape pressing portion 72 connected to the upstream side of the first tape pressing portion 71 via the connecting portion 74 do not have bent portions like the third tape pressing portion 73, and thus can be easily flexed in the vertical direction.

[0073] In Figure 7 and Figure 10 In, a sprocket avoidance hole 80 is provided on the tape cover 70 so as to extend in the Y direction. The sprocket avoidance hole 80 is provided to prevent interference between the feed pin 62P of the positioning sprocket 62B and the tape cover 70.

[0074] In Figure 8 and Figure 9 In, the tape cover 70 is urged (pressed) from above by three urging portions (front pressing portion 81, middle pressing portion 82, and rear pressing portion 83) provided at the front upper portion of the main body portion 51. Here, the front pressing portion 81 has a function of pressing the portion of the tape cover 70 downstream of the component take-out opening 16K against the carrier tape CT on the conveyance surface 61M. The middle pressing portion 82 has a function of pressing the portion between the component take-out opening 16K and the cover tape passage 75 of the tape cover 70 against the carrier tape CT on the conveyance surface 61M. The rear pressing portion 83 has a function of pressing the portion of the tape cover 70 upstream of the cover tape passage 75 against the carrier tape CT on the conveyance surface 61M.

[0075] In this way, in the first embodiment, the entire tape cover 70 is urged toward the conveyance surface 61M side in good balance by the three urging portions (front pressing portion 81, middle pressing portion 82, and rear pressing portion 83). Therefore, the carrier tape CT traveling in the conveyance path 61 in the front upper region of the main body portion 51 including the component take-out position 16T travels while maintaining a state of being pressed against the conveyance surface 61M with an appropriate pressing force. Therefore, the positioning of the component BH at the component take-out position 16T can be accurately performed, and further, the occurrence of a picking error of the component BH by the mounting head 13 can be prevented.

[0076] InFigure 8 and Figure 9 In Figure 9 , the front pressing portion 81 includes a pressing plate 81a as a first swing rod, a pedestal portion 81b, and a first coil spring 81c. The pressing plate 81a extends in the Y direction at the upper front portion of the main body portion 51 (specifically, in a region including above the discharge sprocket 62C and near the carrier tape discharge port 61B). The pedestal portion 81b provided at the downstream end is supported by the main body portion 51 via a support pin 81d extending in the X direction. The first coil spring 81c is provided between the pedestal portion 81b and the main body portion 51 and applies a force in a direction to push up the pedestal portion 81b relative to the main body portion 51.

[0077] As Figure 8 and Figure 9 shown, the upstream end of the pressing plate 81a abuts against the vicinity of the downstream end of the tape cover 70 from above. Therefore, the downstream portion of the tape cover 70 (the third tape pressing portion 73) is in a state of being pushed downward (toward the conveying surface 61M side) by the first coil spring 81c via the pressing plate 81a.

[0078] Thus, in Embodiment 1, the front pressing portion 81 is configured to include: a pressing plate 81a as a first swing rod, which swings about a horizontal axis (support pin 81d) orthogonal to the conveying direction of the carrier tape CT; and a first coil spring 81c, which applies a force to one end of the pressing plate 81a against the upper surface of the tape cover 70. In a state where the carrier tape CT inserted into the conveying path 61 has not reached below the tape cover 70 (referred to as the "initial state", Figure 8 ), the third tape pressing portion 73 is in a state where its lower surface abuts against the conveying surface 61M.

[0079] In Figure 8 and Figure 9 Figure 8 , the middle pressing portion 82 has a spring holding portion 82a, a torsion spring 82b, and a pressing roller 82c. The spring holding portion 82a is formed of a shaft-like member, and both ends of the shaft-like member are supported by side covers 51P provided on the side surfaces (YZ plane) of the main body portion 51 so as to sandwich the conveying path 61 and extend in the X direction. The side covers 51P constitute the main body portion 51.

[0080] In Figure 8 , Figure 9 and Figure 12 Figure 8 , the torsion spring 82b is held by the spring holding portion 82a by inserting its spiral portion (in the X direction) through the spring holding portion 82a. Among the upstream extension portion extending upstream and the downstream extension portion extending downstream, the upstream extension portion is locked to a pin fixed to the side cover 51P. The pressing roller 82c extends in the X direction, and both ends thereof are supported by the two side covers 51P so as to be movable up and down. The pressing roller 82c can rotate about an axis along the X direction.

[0081] The pressing roller 82c is located at the middle part of the tape cover 70 (the part sandwiched between the component removal opening 16K and the cover tape passage 75), and is downwardly biased by the downstream extension of the torsion spring 82b. Therefore, the middle part of the tape cover 70 (the first tape pressing part 71) is in a state of being downwardly biased (pressed) by the torsion spring 82b via the pressing roller 82c toward the lower side (the conveying surface 61M side) ( Figure 12 The pressing force F1 shown in).

[0082] In this way, in the first embodiment, the middle pressing part 82 includes: the pressing roller 82c as a roller pin, which can rotate about a horizontal axis (X axis) intersecting the conveying direction of the carrier tape CT; and the torsion spring 82b as an elastic body, which biases the pressing roller 82c toward the upper surface of the tape cover 70. In the initial state where the carrier tape CT inserted into the conveying path 61 has not reached below the tape cover 70, the lower surface of the second tape pressing part 72 is in a state of abutting against the conveying surface 61M ( Figure 12 ).

[0083] In Figure 8 and Figure 9 shown in, the rear pressing part 83 includes the rear pressing lever 91 as a second swing lever and the second coil spring 92. The rear pressing lever 91 extends in the Y direction at the front upper part of the main body part 51 (specifically, in the area above the guiding sprocket 62A). As Figure 12 shown in, the middle part of the rear pressing lever 91 in the Y direction is supported by the lever swing shaft 93 extending in the X direction, and has an upstream extension 91a extending from the lever swing shaft 93 toward the upstream side and a downstream extension 91b extending toward the downstream side.

[0084] In Figure 12 shown in, the front end part of the downstream extension 91b bends downward and extends, and the pressing lever front end part 91c, which is the front end part of the bent and extended part, is located above the second tape pressing part 72. The second coil spring 92 biases the upstream extension 91a of the rear pressing lever 91 upward, that is, in the direction away from the conveying surface 61M. Therefore, the lever front end part 91c of the rear pressing lever 91 is biased downward, that is, in the direction toward the conveying surface 61M.

[0085] The rotation range of the rear pressing lever 91 is restricted by a pin 94 fixed to the main body portion 51. Therefore, in the initial state where the carrier tape CT has not reached below the contact portion 77 of the second tape pressing portion 72, the rod front end portion 91c is located at a position spaced from the upper surface of the upstream side portion (second tape pressing portion 72) of the tape cover 70 by an interval smaller than the thickness dimension of the carrier tape CT, and the rod front end portion 91c is non-contact with the second tape pressing portion 72. When the carrier tape CT reaches below the contact portion 77 of the second tape pressing portion 72 and the second tape pressing portion 72 is lifted by the carrier tape CT, the second tape pressing portion 72 abuts against the rod front end portion 91c. As a result, the second tape pressing portion 72 is in a state of being urged (pressed) downward (toward the carrier tape CT) by the second coil spring 92 via the rear pressing lever 91 (also refer to Figure 24 ).

[0086] Thus, in the first embodiment, the rear pressing portion 83 includes: a rear pressing lever 91 as a second swing lever that swings about a horizontal axis (rod swing axis 93) orthogonal to the conveyance direction of the carrier tape CT; and a second coil spring 92 that urges one end of the rear pressing lever 91 toward the upper surface of the tape cover 70. In addition, the rear pressing portion 83, together with the middle pressing portion 82, presses an upstream side region (the first tape pressing portion 71 and the second tape pressing portion 72) located upstream of the third tape pressing portion 73, which is a downstream side region of the tape cover 70 where the component extraction opening 16K is formed.

[0087] In Figure 8 、 Figure 9 and Figure 12 a cover tape traction portion 101 is provided at a position upstream of the component extraction position 16T. Specifically, it is provided at a position above the tape cover 70 inside the main body portion 51. The cover tape traction portion 101 has a function of introducing the cover tape TT peeled from the carrier tape CT upward.

[0088] In Figure 11 and Figure 12 the cover tape traction portion 101 is composed of a driving roller 101a and a driven roller 101b having a diameter smaller than that of the driving roller 101a and located downstream of the driving roller 101a. The driving roller 101a is in contact with the driven roller 101b, and when the driving roller 101a rotates counterclockwise in Figure 11 the driven roller 101b rotates clockwise by the driving roller 101a. The driving roller 101a is driven by a transmission gear mechanism (not shown) that transmits the power of the transmission sprocket drive motor 62D. Therefore, the driving roller 101a is driven at the same timing as the carrier tape conveyance portion 62.

[0089] In Figure 8 、 Figure 9 and Figure 12In [the structure], a cover tape discharge path 102 is provided at a position upstream of the cover tape traction portion 101 within the main body portion 51. The cover tape TT tractioned by the cover tape traction portion 101 is discharged into the cover tape discharge path 102.

[0090] In Figure 8 , Figure 9 and Figure 12 [the structure], a correction portion 103 is provided at a position on the upstream side of the tape cover 70 within the main body portion 51 (also refer to Figure 11 ). The correction portion 103 has a function of correcting the leading portion SD of the cover tape TT of the carrier tape CT inserted into the transfer path 61 from the carrier tape inlet 61A when it bends upward or downward.

[0091] As Figure 10 and Figure 11 shown, the correction portion 103 has a swing member 111 and a concave portion 112. The correction portion 103 is disposed at a position upstream of the component extraction position 16T, and has a function of correcting the leading portion SD of the cover tape TT into a state facing downstream from the front end ST of the carrier tape CT as the carrier tape CT is conveyed downstream by the carrier tape conveyance portion 62 and then returns upstream.

[0092] In Figure 11 [the structure], the swing member 111 has: a base portion 111a supported by a rod swing shaft 93 which is the swing shaft of the rear pressing rod 91; and an extension portion 111b extending from the base portion 111a toward the downstream side and having its front end portion bent downward. The swing member 111 tends to swing in the direction of descending toward the front end side of the extension portion 111b ( Figure 11 the clockwise direction in [the structure]), but its swing is restricted by abutting against a swing restricting member (not shown).

[0093] In a state where the swing caused by the self-weight of the swing member 111 is restricted ( Figure 11 the state shown, referred to as the "swing restriction state"), the edge of the lower end of the extension portion 111b (swing member edge 111c) is located at a position separated upward from the transfer surface 61M by a certain interval (dimension gp). And, the dimension gp of this certain interval is an interval larger than the thickness of the cover tape TT and smaller than the sum of the thickness of the carrier tape CT and the thickness of the cover tape TT. It should be noted that in Embodiment 1, the swing member edge 111c is separated from the transfer surface 61M by the dimension gp, but in the case where there is no concern about buckling of the leading portion SD of the cover tape TT, the swing member edge 111c may also be configured to abut against the transfer surface 61M.

[0094] When the swing member edge 111c is pushed up by the carrier tape CT from Figure 11 the swing restriction state shown, the swing member 111 swings in the direction in which the swing member edge 111c is lifted ( Figure 11Oscillate in the counterclockwise direction (in the figure). Then, maintain the state in which the edge 111c of the oscillating member is in contact with the upper surface of the carrier tape CT in this state.

[0095] In Figure 10 and Figure 11 the concave portion 112 has a curved surface 112M formed by the downward depression of a part of the conveying surface 61M. As described above, the conveying surface 61M is formed by the upper edges of two carrier tape support portions 51S opposed to each other in the X direction. Therefore, the concave portion 112 (curved surface 112M) is also formed on the upper edges of these two carrier tape support portions 51S ( Figure 10 ). The upstream edge of the concave portion 112, that is, the concave edge 112E, is located on the downstream side of the oscillating member edge 111c among the respective edges of the upstream side and the downstream side of the concave portion 112 ( Figure 11 ).

[0096] Next, the supply operation of the component BH by the tape feeder 16 will be described. When the carrier tape CT is conveyed by the tape feeder 16 and the component BH is supplied to the component take-out position 16T, the operator first, through the above-described steps, with the leading portion SD protruding from the front end of the carrier tape CT, manually inserts the front end ST of the carrier tape CT into the carrier tape inlet 61A. Then, the carrier tape CT is pressed downstream until the feed hole KH of the front end ST of the carrier tape CT engages with the feed pin 62P of the guide sprocket 62A.

[0097] When the carrier tape CT is inserted from the carrier tape inlet 61A and the feed hole KH near the front end ST of the carrier tape CT engages with the feed pin 62P of the guide sprocket 62A, this situation is detected by a sensor (not shown). After the engagement of the feed hole KH of the carrier tape CT with the feed pin 62P of the guide sprocket 62A is detected by the sensor, the control unit 63 operates the sprocket drive motor 62D to rotate the three sprockets (guide sprocket 62A, positioning sprocket 62B, and discharge sprocket 62C). Alternatively, the operator inserts the carrier tape CT from the carrier tape inlet 61A to engage the feed hole KH with the feed pin 62P of the guide sprocket 62A, operates the operation switch of the tape feeder 16 to operate the sprocket drive motor 62D, and rotates the three sprockets. Thus, the carrier tape conveyance unit 62 starts to convey the carrier tape CT, and the carrier tape CT travels downstream on the conveying surface 61M. It should be noted that at this time, the tape cover 70 is still in the initial state ( Figure 12 ).

[0098] As Figure 13As shown, the front end ST of the carrier tape CT traveling downstream on the conveying surface 61M passes under the edge 111c of the swing member waiting at a position separated from the conveying surface 61M, and then passes through the concave edge 112E. Then, when the front end ST of the carrier tape CT reaches the position P1 which is separated from the position S1 of the concave edge 112E by a specified distance D1 ( Figure 13 ), the control unit 63 temporarily stops the operation of the sprocket drive motor 62D (i.e., temporarily stops the advancement of the carrier tape CT).

[0099] Here, the above-mentioned specified distance D1 is a distance exceeding the length L of the leading portion SD of the cover tape TT (D1 > L). Therefore, at the time point when the rotation of the sprocket drive motor 62D stops (and thus the advancement of the carrier tape CT stops), in the case where the leading portion SD of the cover tape TT is bent upward or downward with respect to the carrier tape CT, the front end of the leading portion SD of the cover tape TT, i.e., the leading end SS (also refer to Figure 3 's (a) and Figure 4 's (b)), is located at a position downstream of both the edge 111c of the swing member and the concave edge 112E ( Figure 13 ). It should be noted that in the case where the leading portion SD of the cover tape TT is neither bent upward nor downward with respect to the carrier tape CT, the leading end SS of the leading portion of the cover tape TT enters the space between the lower surface of the contact portion 77 between the conveying surface 61M and the second tape pressing portion 72 (the space of the gap with the aforementioned dimension GP).

[0100] After temporarily stopping the advancement of the carrier tape CT as described above, the control unit 63 rotates the sprocket drive motor 62D in the reverse direction. As a result, the carrier tape CT travels upstream (i.e., retreats). At the time point when the carrier tape CT starts to retreat, in the case where the leading portion SD of the cover tape TT is in the upwardly bent state as Figure 13 shown, the leading end SS of the leading portion of the cover tape TT abuts against the protruding portion 111b of the swing member 111 and the edge 111c of the swing member from the downstream side ( Figure 14 and Figure 15 ).

[0101] After starting the retreat operation of the carrier tape CT, when the front end ST of the carrier tape CT reaches the position P2 which retreats from the position S2 of the edge 111c of the swing member by a specified distance D2, the control unit 63 stops the operation of the sprocket drive motor 62D ( Figure 16). Here, by setting the above-mentioned specified distance D2 to be smaller than the length L of the leading portion SD of the cover tape TT and larger than half of the length of the leading portion SD (0.5L < D2 < L), at the time point when the backward movement of the carrier tape CT stops, the front end ST of the carrier tape CT is in a state of being located on the upstream side of the swing member edge 111c. In this state, the upward bending state of the leading portion SD of the cover tape TT is released and becomes a state of extending substantially straight toward the downstream side, that is, a state in which the upward bending of the leading portion SD of the cover tape TT is corrected ( Figure 16 ).

[0102] In this way, in the first embodiment, after the front end ST of the carrier tape CT advances a specified distance D1 (to a downstream position that is farther than the length L of the leading portion SD from the concave edge 112E) toward the downstream side of the second correction edge (here, the concave edge 112E), a series of operations (hereinafter referred to as "folding-back operations") are performed to move (recede) the carrier tape CT to an upstream position where its front end ST is separated from the first correction edge (the swing member edge 111c) by a specified distance D2 that is smaller than the length L of the leading portion SD and larger than half of the length L of the leading portion SD. And, by performing this folding-back operation, even when the leading portion SD of the cover tape TT is in an upwardly bent state, it can be eliminated.

[0103] In this way, in the first embodiment, the correction portion 103 includes the swing member 111 that is disposed above the conveyance surface 61M and has the swing member edge 111c as a correction edge at its lower end. In addition, the swing member edge 111c of the swing member 111 waits for the front end of the carrier tape CT to come from the upstream side at a position separated upward from the conveyance surface 61M.

[0104] In addition, when the leading portion SD of the cover tape TT of the carrier tape CT inserted into the carrier tape inlet 61A is in a downwardly bent state of being bent downward with respect to the carrier tape CT, in the above-mentioned folding-back operation, the front end SS of the leading portion of the cover tape TT is hooked on the upstream side edge (the concave edge 112E) of the concave portion 112 ( Figure 17 ). Therefore, in the state where the front end ST of the carrier tape CT is located on the upstream side of the swing member edge 111c after the folding-back operation is completed ( Figure 16 ), the downward bending of the leading portion SD of the cover tape TT is eliminated and becomes a state of extending substantially straight toward the downstream side, that is, a state in which the downward bending of the leading portion SD of the cover tape TT is corrected ( Figure 16 ).

[0105] In this way, in the first embodiment, the concave portion 112 formed on the conveyance surface and the concave edge 112E of the upstream side edge of the concave portion 112 become a part of the correction portion 103.

[0106] After the upper or lower bending of the cover tape TT is corrected by the above-described folding operation of the carrier tape CT ( Figure 16 ), the control unit 63 operates the sprocket drive motor 62D to rotate the three sprockets in the direction in which the carrier tape CT travels downstream. As a result, the front end ST of the carrier tape CT passes through the edge 111c of the swing member downstream, and the front end SS of the leading portion of the cover tape TT in the state of extending downstream enters below the inclined portion 78 of the second tape pressing portion 72 of the tape cover 70 ( Figure 18 ). Further, the front end SS of the leading portion of the cover tape TT enters the space (the space of the gap having the size GP) between the second tape pressing portion 72 and the conveyance surface 61M ( Figure 19 ).

[0107] Here, when the leading portion SD of the cover tape TT (which has been corrected by the correction portion 103 and is in the state of extending downstream) (or the leading portion SD of the cover tape TT that has neither been bent upward nor downward with respect to the carrier tape CT since being inserted from the carrier tape insertion port 61A) slightly warps upward before entering the space (the space of the gap having the size GP) between the contact portion 77 of the second tape pressing portion 72 and the conveyance surface 61M (refer to the leading portion indicated by the reference numeral "SD1" in Figure 18 ), the front end SS of the leading portion travels downstream along the tapered surface 78M of the second tape pressing portion 72. Therefore, the situation where the leading portion SD of the cover tape TT temporarily corrected by the edge 111c of the swing member and the edge 112E of the concave portion bends upward again is prevented. In this way, the lower surface (tapered surface 78M) of the inclined portion 78 of the second tape pressing portion 72 becomes an upward bending prevention surface for preventing the upward bending of the cover tape TT.

[0108] In addition, when the leading portion SD of the cover tape TT slightly warps downward before entering the space between the second tape pressing portion 72 and the conveyance surface 61M (refer to the leading portion indicated by the reference numeral "SD2" in Figure 18 ), the front end SS of the leading portion travels downstream along the curved surface 112M of the concave portion 112. Therefore, the situation where the leading portion SD of the cover tape TT temporarily corrected by the edge 111c of the swing member and the edge 112E of the concave portion bends downward again is prevented. In this way, the surface (curved surface 112M) of the concave portion 112 becomes a downward bending prevention surface for preventing the downward bending of the cover tape TT in a state where the cover tape TT is bent downward with respect to the carrier tape CT.

[0109] The leading portion SD of the cover tape TT that has entered the space (the gap space having the size GP) between the contact portion 77 of the second tape pressing portion 72 and the conveyance surface 61M abuts against the stopper portion 76 that abuts against the conveyance surface 61M and is blocked, preventing the leading portion SD from further traveling downstream ( Figure 20). Further, when the carrier tape CT is further conveyed downstream, the front end SS of the leading portion of the cover tape TT passes upward through the cover tape passage 75 and protrudes upward (i.e., above the second tape pressing portion 72 (i.e., the tape cover 70)) Figure 21 ).

[0110] In this way, the stopper portion 76 provided in the first tape pressing portion 71 has the following function: in a state where the first tape pressing portion 71 is in contact with the conveyance surface 61M, it blocks the front end SS of the leading portion of the cover tape TT traveling from the upstream side from entering between the first tape pressing portion 71 and the conveyance surface 61M. In the first embodiment, the first tape pressing portion 71 includes a stopper portion 76 located on the downstream side of the second tape pressing portion 72 and disposed on the conveyance surface 61M, and serves as a carrier tape pressing portion that presses the carrier tape CT on the conveyance surface 61M.

[0111] As described above, the control unit 63 controls the air ejection control valve 66 when the front end SS of the leading portion of the cover tape TT reaches (or is about to reach) the cover tape passage 75 of the tape cover 70, so that the air 107 is ejected upward from the air ejection portion 65 ( Figure 21 ). The air ejection portion 65 is provided at a position where the ejected air 107 passes through the cover tape passage 75 from below.

[0112] If the air 107 is ejected from the air ejection portion 65 when the front end SS of the leading portion of the cover tape TT reaches the cover tape passage 75, the front end SS of the leading portion of the cover tape TT is guided by the flow of the air 107 ejected from the air ejection portion 65 and passes upward through the cover tape passage 75 and protrudes above the tape cover 70. Further, the carrier tape CT moves upward as it travels downstream and reaches between the driving roller 101a and the driven roller 101b that constitute the cover tape traction portion 101 ( Figure 22 ).

[0113] In this way, in the first embodiment, the air ejection portion 65 serves as an auxiliary portion that assists the movement of the leading portion SD in the direction toward the cover tape traction portion 101 by the flow of air (i.e., gas). Further, in the first embodiment, the first tape pressing portion 71 including the stopper portion 76 as the carrier tape pressing portion and the air ejection portion 65 as the auxiliary portion serve as a guiding portion 140 that guides the leading portion SD toward the cover tape traction portion 101.

[0114] The front end SS of the leading portion of the cover tape TT that reaches between the driving roller 101a and the driven roller 101b is caught by the cover tape traction portion 101 (by the reverse rotation of the driving roller 101a and the driven roller 101b) and is pulled upward ( Figure 23 ).

[0115] As described above, after the leading portion SD of the cover tape TT passes upward through the cover tape path 75, the front end ST of the carrier tape CT abuts against the conical surface 78M of the second tape pressing portion 72 ( Figure 21 ). When the carrier tape CT with the front end ST abutting against the conical surface 78M further travels downstream, the second tape pressing portion 72 is pushed upward by the carrier tape CT ( Figure 21 → Figure 22 ).

[0116] The second tape pressing portion 72 pushed upward by the carrier tape CT pulls the first tape pressing portion 71 upward through the connecting portion 74. Therefore, a gap G through which the carrier tape CT can travel is formed between the first tape pressing portion 71 and the conveying surface 61M ( Figure 22 ). The stopper portion 76, which is the upstream edge of the first tape pressing portion 71, also rises from the conveying surface 61M. After the gap G is formed between the first tape pressing portion 71 and the conveying surface 61M, the carrier tape CT travels downstream within this gap ( Figure 22 → Figure 23 ).

[0117] In this way, the second tape pressing portion 72 becomes a contact displacement portion that is displaced by contacting the carrier tape CT, and the connecting portion 74 becomes a transmission portion that transmits the displacement of the second tape pressing portion 72 as the contact displacement portion to the first tape pressing portion 71 to displace the stopper portion 76. Moreover, the second tape pressing portion 72 as the contact displacement portion and the connecting portion 74 as the transmission portion become a height changing portion 70T that lifts the stopper portion 76 upward from the conveying surface 61M ( Figure 7 ).

[0118] As described above, when the second tape pressing portion 72 is pushed upward by the carrier tape CT, the inclined portion 78 of the second tape pressing portion 72 abuts against the front end portion 91c of the pressing rod of the rear pressing portion 83 from below and pushes the front end portion 91c upward. As a result, the second coil spring 92 of the rear pressing portion 83 is compressed by the upstream extending portion 91a of the rear pressing rod 91, and a reaction force thereof applies an upward force to the upstream extending portion 91a. Therefore, the second tape pressing portion 72 (inclined portion 78) is applied with a downward force by the second coil spring 92 via the rear pressing rod 91 ( Figure 24 the pressing force F2 shown therein).

[0119] In this way, in the first embodiment, when the carrier tape CT is not in the conveying path 61, the rear pressing rod 91 is non-contact with the tape cover 70, and after the rear pressing portion 83 contacts the tape cover 70 (specifically, the second tape pressing portion 72) that has been displaced upward by the carrier tape CT, it presses the tape cover 70 downward.

[0120] When the carrier tape CT travels downstream within the gap formed between the lower surface of the first tape pressing portion 71 and the conveying surface 61M, the cover tape TT extending upward through the cover tape passage 75 is further introduced upward (into the cover tape discharge path 102) by the cover tape pulling portion 101 ( Figure 25 ).

[0121] In this way, in Embodiment 1, the cover tape pulling portion 101 is structured to introduce the cover tape TT peeled off from the carrier tape CT.

[0122] In Embodiment 1, the tape cover 70 and the cover tape pulling portion 101 constitute the cover tape peeling portion 120 ( Figure 8 ). (Also refer to Figure 6 and Figure 11 ). Here, the cover tape peeling portion 120 refers to the following functional portion: arranged downstream of the correction portion 103 and upstream of the component taking-out position 16T, capturing and introducing the leading portion SD of the cover tape TT extending downstream from the front end ST of the carrier tape CT, thereby peeling the cover tape TT from the upper surface of the carrier tape CT conveyed downstream by the carrier tape conveying portion 62.

[0123] The carrier tape CT from which the cover tape TT has been peeled off by the cover tape peeling portion 120 is conveyed downstream on the conveying path 61 by the carrier tape conveying portion 62, and the first component receiving groove PK in the carrier tape CT is positioned at the component taking-out position 16T. Thus, the positioning process of the carrier tape CT ends. The carrier tape conveying portion 62 continuously performs the operation (positioning process of the carrier tape CT) from the position P2 until the first component receiving groove PK in the carrier tape CT is positioned at the component taking-out position 16T.

[0124] During the positioning process of the carrier tape CT, the cover tape TT is peeled off from the carrier tape CT by the cover tape peeling portion 120. After that, along with the operation (pick-up operation) of the mounting head 13 provided in the component mounting device 1 adsorbing and taking out the component BH, pitch feeding is performed by the carrier tape conveying portion 62 to sequentially position the component receiving grooves PK at the component taking-out position 16T (carrier tape positioning operation).

[0125] In this way, in Embodiment 1, the tape feeder 16 as the component supply device is structured to peel the cover tape TT having the leading portion SD extending from the front end of the carrier tape CT from the carrier tape CT, expose the component BH stored in the carrier tape CT in a state covered by the cover tape TT, and convey the exposed component BH to the component taking-out position 16T and supply it to the component mounting device 1.

[0126] When the component mounting apparatus 1 with the tape feeder 16 having the above structure performs a component mounting operation of mounting the component BH on the substrate KB, first, the substrate KB supplied from the outside of the component mounting apparatus 1 is carried in by the substrate transfer unit 12 and positioned at a predetermined operation position. After the substrate KB is positioned at the operation position, each tape feeder 16 supplies the component BH to the component extraction opening 16K, and the mounting head 13 holds and extracts the component BH from the component extraction position 16T of the tape feeder 16 through the component holding nozzle 14. The mounting head 13 that has extracted the component BH from the component extraction position 16T of the tape feeder 16 moves above the substrate KB and mounts the component BH at the target component mounting position determined on the substrate KB. After all the components BH to be mounted on the substrate KB are mounted, the substrate KB is carried out of the component mounting apparatus 1 by the substrate transfer unit 12. Thus, the component mounting operation for one substrate KB is completed.

[0127] As described so far, the tape feeder 16 in the first embodiment transports the carrier tape CT along the transport path 61 with the leading portion SD of the cover tape TT advanced first, and returns the carrier tape CT being transported downstream upstream, so that the bending state of the leading portion SD can be corrected by the correction unit 103. Therefore, even when the leading portion SD of the cover tape TT is bent, it can be reliably captured by the cover tape traction unit 101.

[0128] In addition, the tape feeder 16 in the first embodiment includes a guiding portion 140 that guides the leading portion SD toward the cover tape traction unit 101, and the leading portion SD of the cover tape TT is blocked by the stopper portion 76 and guided. Therefore, the leading portion SD of the cover tape TT can be reliably guided and captured toward the cover tape traction unit 101. It should be noted that after the leading portion SD of the cover tape TT is captured by the cover tape traction unit 101, the stopper portion 76 is lifted upward by the height changing unit 70T, so that the carrier tape CT can travel on the transport path 61 without being blocked by the stopper portion 76, and the transport of the carrier tape CT is not hindered. The guiding portion 140 in the tape feeder 16 in the first embodiment includes a carrier tape pressing portion (first tape pressing portion 71) that presses the carrier tape CT on the transport surface 61M downstream of the contact displacement portion (second tape pressing portion 72).

[0129] In addition, in the tape feeder 16 of the first embodiment, for the tape cover 70 having the component extraction opening 16K and the cover tape passage 75, the portion downstream of the component extraction opening 16K is pressed by the front pressing portion 81, the portion sandwiched between the component extraction opening 16K and the cover tape passage 75 is pressed by the middle pressing portion 82, and the portion upstream of the cover tape passage 75 is pressed by the rear pressing portion 83, and the entire tape cover 70 is pressed against the transport path 61 with an appropriate balance. Therefore, the transport of the carrier tape CT in the area including the vicinity of the component extraction position 16T can be stably performed, and the extraction accuracy of the component BH can be improved.

[0130] (Embodiment 2)

[0131] Figure 26 Fig. shows a part of the tape feeder in Embodiment 2. The correction edge of the tape feeder in Embodiment 2 is only the correction edge (the swing member edge 111c in Embodiment 1) facing the upper surface of the carrier tape CT. Except for this point, it is the same as the tape feeder 16 in Embodiment 1.

[0132] The difference between Embodiment 2 and Embodiment 1 is that the correction part 103 does not have the concave part 112. This is a structure that can be adopted when the leading part SD of the cover tape TT of the carrier tape CT inserted from the carrier tape inlet 61A does not bend downward, that is, when inserting the carrier tape CT from the carrier tape inlet 61A, the leading part SD of the cover tape TT is bent upward in advance, that is, the leading part SD is set in an upward-bent state and the carrier tape CT is inserted into the carrier tape inlet 61A. In Embodiment 2, since the correction part 103 also has a correction edge, the same effect as the tape feeder 16 in Embodiment 1 can be obtained.

[0133] (Embodiment 3)

[0134] Figure 27 Fig. shows a part of the tape feeder in Embodiment 3. The correction edge of the tape feeder in Embodiment 3 is only the edge of the concave part 112 formed on the conveyance surface 61M. Except for this point, it is the same as the tape feeder 16 in Embodiment 1.

[0135] The difference between Embodiment 3 and Embodiment 1 is that the correction part 103 does not have the swing member 111. This is a structure that can be adopted when the leading part SD of the cover tape TT of the carrier tape CT inserted from the carrier tape inlet 61A does not bend upward, that is, when inserting the carrier tape CT from the carrier tape inlet 61A, the leading part SD of the cover tape TT is bent downward in advance, that is, the leading part SD is set in a downward-bent state and the carrier tape CT is inserted into the carrier tape inlet 61A. In Embodiment 3, since the correction part 103 also has a correction edge, the same effect as the tape feeder 16 in Embodiment 1 can be obtained.

[0136] (Embodiment 4)

[0137] Figure 28FIG. 0 shows a part of the tape feeder in Embodiment 4. The tape feeder in Embodiment 4 does not have the air ejection portion 65 that appears in Embodiment 1. Instead, a channel 130 that covers the cover tape discharge path 102 and a suction portion 131 for sucking the air 107 are provided in the channel 130. Except for this point, it is the same as the tape feeder 16 in Embodiment 1. The guide portion 140 of Embodiment 4 is configured to include a first tape pressing portion 71 and a suction portion 131.

[0138] In Embodiment 4, by using the suction portion 131 provided on the upper side of the conveyance surface 61M to suck the air 107 in the channel 130, it is not necessary to have the air ejection portion 65 in Embodiment 1, and the leading portion SD of the cover tape TT is reliably pulled by the cover tape traction portion 101 through the cover tape path 75. That is, in Embodiment 4, the suction portion 131, like the aforementioned air ejection portion 65, becomes an auxiliary portion that uses the gas flow to assist the movement of the leading portion SD in the direction toward the cover tape traction portion 101. The suction portion 131 also functions to guide the front end SS of the leading portion of the cover tape TT toward the cover tape traction portion 101 in the same manner as the air ejection portion 65. Therefore, in Embodiment 4, the same effect as the tape feeder 16 in Embodiment 1 can be obtained.

[0139] (Embodiment 5)

[0140] Figure 29 FIG. 10 shows a part of the tape feeder in Embodiment 5. The tape feeder in Embodiment 5 does not have the air ejection portion 65 that appears in Embodiment 1. Instead, a guide member 132 is provided on the downstream side above the cover tape path 75. Except for this point, it is the same as the tape feeder 16 in Embodiment 1. In addition, the stopper portion 76 does not block the advancement of the leading portion SD of the cover tape TT, but changes the leading portion SD into a shape that is easy to move upward from the cover tape path 75. The guide portion 140 of Embodiment 5 is configured to include a first tape pressing portion 71 and a guide member 132.

[0141] In Embodiment 5, the leading portion SD that abuts against the stopper portion 76 changes its moving direction upward and protrudes above the tape cover 70 through the cover tape path 75. The leading portion SD of the cover tape TT that has moved above the tape cover 70 is guided by the guide member 132 toward the cover tape traction portion 101. Therefore, the capture of the leading portion SD of the cover tape TT by the cover tape traction portion 101 can be reliably performed, and the same effect as the tape feeder 16 in Embodiment 1 can be obtained.

[0142] (Embodiment 6)

[0143] Figure 30Shows a part of the tape feeder of the sixth embodiment. The tape feeder in Embodiment 6 does not have an air ejection part 65. The shape of the stopper part 76 of the tape cover 70 (especially the height from the conveying surface 61M), the dimensions, arrangements, etc. of the driving roller 101a and the driven roller 101b that constitute the cover tape traction part 101 are different from those in Embodiment 1. Except for this point, it is the same as the tape feeder 16 in Embodiment 1. In addition, the stopper part 76 does not block the advancement of the leading part SD of the cover tape TT, but changes the leading part SD into a shape that is easy to go upward from the cover tape passage 75. The guiding part 140 in Embodiment 6 is only composed of the first tape pressing part 71.

[0144] In Embodiment 6, the aforementioned auxiliary parts (such as the air ejection part 65, the suction part 131, the guiding member 132, etc.) are not required, and the leading part SD of the cover tape TT protruding above the tape cover 70 through the cover tape passage 75 can be guided to the cover tape traction part 101. Therefore, in Embodiment 6, the same effect as the tape feeder 16 in Embodiment 1 can also be obtained.

[0145] As described above, the component supply device (tape feeder 16) in Embodiments 1 to 6 conveys the carrier tape CT along the conveying path 61 with the leading part SD of the cover tape TT leading, and returns the carrier tape CT conveyed downstream upstream. Thus, the bending state of the leading part SD can be corrected by the correcting part 103. Therefore, even when the leading part SD of the cover tape TT is bent, it can be reliably captured by the cover tape traction part 101.

[0146] So far, the embodiments of the present invention have been described, but the present invention is not limited to the above content and can be variously deformed, etc. For example, as in Embodiments 1, 2, 4 to 6 above, when the swing member 111 is in a swing-restricted state, waiting for the advancement of the carrier tape CT with the swing member edge 111c separated from the conveying path 61, this structure can be replaced by waiting for the advancement of the carrier tape CT with the swing member edge 111c in contact with the conveying surface 61M. In this case, it is configured such that the conveying surface 61M functions as the swing restricting member in Embodiment 1.

[0147] Industrial Applicability

[0148] The present invention provides a component supply device that can be reliably captured by a cover tape traction part even when the leading part of the cover tape is bent.
