[0040] (Implementation method 1)

[0041] Figure 1 A component loading device 1 with a belt feeder is shown as a component supply device according to Embodiment 1 of the present invention. The component loading device 1 is a device for loading a component BH on a substrate KB, and is provided with a substrate conveying unit 12 on a base 11. The substrate conveying unit 12 conveys the substrate KB in a horizontal direction and positions it at a predetermined working position. Hereinafter, for the sake of convenience of explanation, the conveying direction of the substrate KB conveyed by the substrate conveying unit 12 is set as the X direction, the horizontal direction orthogonal to the X direction is set as the Y direction, and the up and down direction is set as the Z direction. In addition, the direction toward the center side of the base 11 in the Y direction is referred to as the "front", and the direction toward the opposite side thereof is referred to as the "rear".

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

[0043] exist Figure 1 In the embodiment, a carriage 15 is connected to the end 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 mounted on the feeder base 21 in the X direction.

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

[0045] The table 31 is provided with mounting slots 35 arranged along the X direction for mounting the tape feeder 16. Figure 2As shown in Fig. (a), an assembly slot 35 is composed of a pair of feeder guide portions 41 arranged along the X direction on the feeder support portion 33, two positioning holes 42 (upper and lower) which are through holes penetrating the wall portion 32 in the thickness direction (Y direction), 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 along the X direction.

[0046] The feeder guide portion 41 is 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 two upper and lower positioning holes 42 are arranged along the Z direction. The assembly hole 44, the electrical socket 45, and the air socket 46 are arranged along 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 supply feeder 16 is wound. As Figure 3 shown in Figs. (a) and (b), a plurality of component receiving 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 receiving grooves PK.

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

[0049] As Figure 3 shown in Figs. (a) and (b) or Figure 4 shown in Figs. (a) and (b), 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 Figure 3 Figs. (a) and (b), 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 Figure 4 Figs. (a) and (b).

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

[0051] In Figure 5 of (a), (b) and Figure 6 In, the tape feeder 16 has a main body portion 51 detachably assembled to the assembly slot 35 of the feeder base 21. Two positioning pins 52 protruding forward are provided at the front end portion of the main body portion 51.

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

[0053] When the tape feeder 16 is assembled to the assembly slot 35, the engaged portion 51K ( Figure 6 ) provided at the lower portion of the main body portion 51 is inserted between the feeder guide portions 41 constituting the assembly slot 35 ( Figure 2 of (a) → Figure 2 of (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 electrical 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 assembly hole 44, the fixed portion 54 is connected to a fixed 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 signal-transmission connected to 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] In Figure 6 In, a conveyance path 61 for conveying the carrier tape CT is provided inside the main body portion 51. The conveyance path 61 has a carrier tape inlet 61A at the rear end portion of the main body portion 51 and a carrier tape outlet 61B at the front end portion of the main body portion 51. The upper surface of the conveyance path 61 serves as a conveyance surface 61M for supporting and conveying the lower surface of the carrier tape CT (see Figure 8 ). That is, in the first embodiment, the conveyance path 61 has a conveyance surface 61M that supports the carrier tape CT from below.

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

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

[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 from 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 (inlet sprocket 62A, positioning sprocket 62B, and discharge sprocket 62C) rotated by the sprocket drive motor 62D, that is, the carrier tape conveyance unit 62. At this time, the carrier tape CT is handed over in the order of the inlet sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C.

[0059] The carrier tape CT inserted from the carrier tape inlet 61A is conveyed by the carrier tape conveyance unit 62 toward the downstream side, that is, the carrier tape outlet 61B. The carrier tape CT conveyed toward the downstream side is peeled off the cover tape TT before passing through the component removal opening 16K provided in the front upper portion of the main body portion 51. At the time of passing through the component removal 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 removal 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 removal position 16T set inside the component removal opening 16K in sequence. Thus, the mounting head 13 can adsorb and hold the component BH located at the component removal opening 16K (component removal 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 removal position 16T.

[0061] In Figure 6 this, 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 front upper portion of the main body portion 51 through an air pipe 64 provided in the lower extension portion 53. An air ejection control valve 66 provided in the lower extension portion 53 is interposed in the air pipe 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 a front upper portion of the main body portion 51 is provided with Figure 7 the tape cover 70 shown. Specifically, as Figure 8 well as Figure 9 shown, it is provided so as to cover from above a portion of the conveyance path 61 between the positioning sprocket 62B and the discharge sprocket 62C. The tape cover 70 is constituted by a single plate-like member in the first embodiment and is detachable from and attachable to the main body portion 51.

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

[0065] As Figure 10 shown, the tape cover 70 is provided in the front upper portions of the two 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 tape support portions 51S. As described above, the conveyance surface 61M is constituted by the upper edges of the two tape support portions 51S, and both end portions of the carrier tape CT are supported from below by the upper edges of the two tape support portions 51S. Therefore, the carrier tape CT can use not only a type without a downward protruding portion (so-called paper tape type), but also an embossed type having an embossed portion protruding downward.

[0066] In Figure 7 and Figure 10 the tape cover 70 includes a first tape pressing portion 71 that constitutes the central part thereof, a second tape pressing portion 72 that constitutes a portion closer to the upstream side than the first tape pressing portion 71, and a third tape pressing portion 73 that constitutes a portion closer to the downstream side than 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 width direction of the tape cover 70, i.e., the side in the X direction). The above-described component removal opening 16K ( Figure 7 ) is formed in the third tape pressing portion 73.

[0067] Thus, in Embodiment 1, the tape cover 70 is configured to cover the upper surface of the carrier tape CT conveyed by the carrier tape conveyance unit 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 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 (i.e., 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 provided on the carrier tape CT conveyed by the carrier tape conveyance unit 62 and guides the leading portion SD upward (toward 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 via a 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 stopper portion 76, which is the upstream edge of the first tape pressing portion 71.

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

[0071] In Figure 11 , in a 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 with a size of GP 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 larger than the thickness of the cover tape TT but smaller than the thickness of the carrier tape CT.

[0072] In Figure 7In [description], both ends 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 ends in the width direction in this way, the bending rigidity in the vertical direction becomes high and it is difficult to flex. Thereby, 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, so they can be easily flexed in the vertical direction.

[0073] In Figure 7 and Figure 10 In [description], 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 [description], 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 in a well-balanced manner by the three urging portions (front pressing portion 81, middle pressing portion 82, and rear pressing portion 83). Therefore, the carrier tape CT traveling on 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] In Figure 8 and Figure 9In [the structure], the front pressing portion 81 includes a pressing plate 81a serving 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 part 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 disposed 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 downwardly (towards the conveying surface 61M side) pushed (pressed) by the first coil spring 81c via the pressing plate 81a.

[0078] In this way, in Embodiment 1, the front pressing portion 81 is configured to include: a pressing plate 81a serving 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 towards 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 [the structure], 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 in a manner sandwiching 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 [the structure], the torsion spring 82b is held by the spring holding portion 82a by inserting its helical portion (in the X direction) through the spring holding portion 82a. Among the upstream extending portion extending upstream and the downstream extending portion extending downstream, the upstream extending 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: a 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 a 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 Figure 12 , the rear pressing part 83 includes a rear pressing lever 91 as a second swing lever and a second coil spring 92. The rear pressing lever 91 extends in the Y direction at the upper front part of the main body part 51 (specifically, in the area above the guide sprocket 62A). As shown in Figure 12 , the middle part of the rear pressing lever 91 in the Y direction is supported by a lever swing shaft 93 extending in the X direction, and has an upstream extension 91a extending upstream from the lever swing shaft 93 and a downstream extension 91b extending downstream.

[0084] In Figure 12 , 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 front end portion 91c of the lever 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 front end portion 91c of the lever 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 front end portion 91c of the lever. 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, which swings about a horizontal axis (lever swing axis 93) orthogonal to the conveying direction of the carrier tape CT; and a second coil spring 92, which 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 (first tape pressing portion 71 and second tape pressing portion 72) located upstream of a downstream side region of the tape cover 70 where the component removal opening 16K is formed, i.e., the third tape pressing portion 73.

[0087] In Figure 8 、 Figure 9 and Figure 12 , a cover tape traction portion 101 is provided at a position upstream of the component removal position 16T. Specifically, it is provided at an upper position of the tape cover 70 within the main body portion 51. The cover tape traction portion 101 has a function of pulling the cover tape TT peeled off 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 driving motor 62D. Therefore, the driving roller 101a is driven at the same timing as the carrier tape conveying portion 62.

[0089] In Figure 8 、 Figure 9 and Figure 12In [the device], 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 device], 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 conveying path 61 from the carrier tape introduction port 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 arranged 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 moves downstream after being conveyed by the carrier tape conveying portion 62 and then returns upstream.

[0092] In Figure 11 [the device], 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 device]), 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 conveying surface 61M by a certain interval (dimension gp). And, the dimension gp of this certain interval is larger than the thickness of the cover tape TT and smaller than the sum of the thicknesses of the carrier tape CT and the cover tape TT. It should be noted that in Embodiment 1, the swing member edge 111c is separated from the conveying 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 conveying 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, in this state, maintain the state where the edge 111c of the oscillating member is in contact with the upper surface of the carrier tape CT.

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

[0096] Next, the supply operation of the component BH by the tape feeder 16 will be described. When the component BH is supplied to the component take-out position 16T by transporting the carrier tape CT by the tape feeder 16, 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 situation where the feed hole KH of the carrier tape CT has engaged 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 (the guide sprocket 62A, the positioning sprocket 62B, and the 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 transport unit 62 starts transporting 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 recess 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 recess edge 112E by a predetermined 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 predetermined 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 when the rotation of the sprocket drive motor 62D stops (and thus the advancement of the carrier tape CT stops), when 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 recess edge 112E ( Figure 13 ). It should be noted that when 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 of 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 when the carrier tape CT starts to retreat, when 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 predetermined 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 upstream of the edge 111c of the swing member. In this state, the upwardly bent state of the leading portion SD of the cover tape TT is released, and it becomes a state of extending substantially straight toward the downstream side, that is, a state in which the upward bend of the leading portion SD of the cover tape TT is corrected ( Figure 16 ).

[0102] In this way, in Embodiment 1, after the front end ST of the carrier tape CT advances a specified distance D1 (to a downstream position that is farther from the concave edge 112E than the length L of the leading portion SD) toward the downstream side of the correction edge (here, the concave edge 112E), a series of operations (hereinafter referred to as "turn-back operation") are performed to move (recede) the carrier tape CT to an upstream position where its front end ST is separated from the correction edge (the edge 111c of the swing member) 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 turn-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 Embodiment 1, the correction portion 103 includes a swing member 111 that is disposed above the conveyance surface 61M and has an edge 111c of the swing member as a correction edge at its lower end. In addition, the 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 turn-back operation, the front end SS of the leading portion of the cover tape TT is hooked on the upstream 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 upstream of the edge 111c of the swing member after the turn-back operation is completed ( Figure 16 ), the downward bend of the leading portion SD of the cover tape TT is eliminated, and it becomes a state of extending substantially straight toward the downstream side, that is, a state in which the downward bend of the leading portion SD of the cover tape TT is corrected ( Figure 16 ).

[0105] In this way, in Embodiment 1, the concave portion 112 formed on the conveyance surface and the concave edge 112E of the upstream 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 turning-back operation of the carrier tape CT as described above ( Figure 16 ), the control unit 63 operates the sprocket drive motor 62D to rotate the three sprockets in the direction of causing the carrier tape CT to travel 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 between the second tape pressing portion 72 and the conveying surface 61M (the space of the gap with the dimension GP) ( Figure 19 ).

[0107] Here, when the leading portion SD of the cover tape TT that 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 inlet 61A) slightly warps upward before entering the space between the contact portion 77 of the second tape pressing portion 72 and the conveying surface 61M (the space of the gap with the dimension GP) (refer to Figure 18 the leading portion indicated by the reference numeral "SD1" in the figure), the front end SS of this leading portion travels downstream along the conical 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 (conical 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 conveying surface 61M (refer to Figure 18 the leading portion indicated by the reference numeral "SD2" in the figure), 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 the 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 between the contact portion 77 of the second tape pressing portion 72 and the conveying surface 61M (the gap space with the dimension GP) abuts against the stopper portion 76 that abuts against the conveying 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 from the upper side of 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 conveying surface 61M, it blocks the front end SS of the leading portion of the cover tape TT coming from the upstream side from entering between the first tape pressing portion 71 and the conveying surface 61M. In the first embodiment, the first tape pressing portion 71 includes the stopper portion 76 located on the downstream side of the second tape pressing portion 72 and disposed on the conveying surface 61M, and serves as a tape pressing portion for pressing the carrier tape CT on the conveying surface 61M.

[0111] The control unit 63 controls the air ejection control valve 66 at the timing when (or just before) the front end SS of the leading portion of the cover tape TT reaches the cover tape passage 75 of the tape cover 70 as described above, 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 at the timing 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 upward from 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 constituting 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 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 captured 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 tapered surface 78M of the second tape pressing portion 72 ( Figure 21 ). When the carrier tape CT with the front end ST abutting against the tapered 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 conveyance surface 61M ( Figure 22 ). The stopper portion 76, which is the upstream edge of the first tape pressing portion 71, also rises from the conveyance surface 61M. After the gap G is formed between the first tape pressing portion 71 and the conveyance 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, which is the contact displacement portion, to the first tape pressing portion 71 to displace the stopper portion 76. Further, 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 conveyance 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 in

[0119] In this way, in the first embodiment, when the carrier tape CT is not in the conveyance path 61, the rear pressing rod 91 is non-contact with the tape cover 70, and when 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, the rear pressing portion 83 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 pulled upward (into the cover tape discharge path 102) by the cover tape pulling portion 101 ( Figure 25 ).

[0121] Thus, in Embodiment 1, the cover tape pulling portion 101 is configured to pull 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: disposed downstream of the correction portion 103 and upstream of the component removal position 16T, capturing and pulling 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 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 removal position 16T. Thus, the positioning process of the carrier tape CT ends. The carrier tape conveying portion 62 continuously performs the operation (the 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 removal position 16T.

[0124] During the positioning process of the carrier tape CT, the cover tape TT is peeled 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 of the component mounting device 1 adsorbing and removing the component BH, the pitch feed is performed by the carrier tape conveying portion 62, and the component receiving grooves PK are sequentially positioned at the component removal position 16T (carrier tape positioning operation).

[0125] Thus, in Embodiment 1, the tape feeder 16 as the component supply device is configured 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 accommodated in the carrier tape CT in a state covered by the cover tape TT, and convey the exposed component BH to the component removal position 16T and supply it to the component mounting device 1.

[0126] When the component mounting device 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 device 1 is carried in by the substrate transfer unit 12 and positioned at a specified 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 device 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, 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 region 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 portion 103 does not have the concave portion 112. This is a structure that can be adopted in the case where the leading portion 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 the carrier tape CT is inserted from the carrier tape inlet 61A, the leading portion SD of the cover tape TT is bent upward in advance, that is, the leading portion SD is set in an upwardly bent state and the carrier tape CT is inserted into the carrier tape inlet 61A. In Embodiment 2, since the correction portion 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 portion 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 portion 103 does not have the swing member 111. This is a structure that can be adopted in the case where the leading portion 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 the carrier tape CT is inserted from the carrier tape inlet 61A, the leading portion SD of the cover tape TT is bent downward in advance, that is, the leading portion SD is set in a downwardly bent state and the carrier tape CT is inserted into the carrier tape inlet 61A. In Embodiment 3, since the correction portion 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 that sucks 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 guiding 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 above the conveying 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 pulling 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 assisting portion that uses the gas flow to assist the movement of the leading portion SD in the direction toward the cover tape pulling 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 pulling portion 101 in the same manner as the air ejection portion 65. Therefore, in Embodiment 4, the same effect as that of 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 guiding 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 guiding portion 140 of Embodiment 5 is configured to include a first tape pressing portion 71 and a guiding member 132.

[0141] In Embodiment 5, the leading portion SD in contact with 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 guiding member 132 toward the cover tape pulling portion 101. Therefore, the capture of the leading portion SD of the cover tape TT by the cover tape pulling portion 101 can be reliably performed, and the same effect as that of 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 portion 65. The shape of the stopper portion 76 of the tape cover 70 (particularly the height from the conveyance surface 61M), the dimensions, arrangements, etc. of the drive roller 101a and the driven roller 101b constituting the cover tape traction portion 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 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 easily directed upward from the cover tape passage 75. The guiding portion 140 in Embodiment 6 is composed only of the first tape pressing portion 71.

[0144] In Embodiment 6, without the need for the aforementioned auxiliary portions (such as the air ejection portion 65, the suction portion 131, the guiding member 132, etc.), the leading portion SD of the cover tape TT protruding upward from the cover tape passage 75 can be guided to the cover tape traction portion 101. Therefore, in Embodiment 6, the same effects as those of 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 includes a guiding portion that includes a stopper portion 76 disposed on the conveyance surface 61M and guides the leading portion SD toward the cover tape traction portion 101. The leading portion SD of the cover tape TT is blocked by the stopper portion 76 and guided by the guiding portion. Therefore, the cover tape TT can be reliably peeled off from the carrier tape CT. It should be noted that after the leading portion SD of the cover tape TT is caught by the cover tape traction portion 101, the stopper portion 76 is lifted upward by the height changing portion 70T. Therefore, the carrier tape CT is not blocked by the stopper portion 76 and can travel on the conveyance path 61, without hindering the conveyance of the carrier tape CT.

[0146] Thus 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 modified. 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 in a state where the swing member edge 111c is separated from the conveyance path 61, it is also possible to set it to wait for the advancement of the carrier tape CT in a state where the swing member edge 111c is in contact with the conveyance surface 61M. In this case, it is configured such that the conveyance surface 61M functions as the swing restricting member in Embodiment 1.
