(First exemplary embodiment)

[0007] Fig. 1 shows the component mounting apparatus 1, which includes a tape feeder as a component feeding apparatus according to a first exemplary embodiment of the present invention. The component mounting apparatus 1 is an apparatus for mounting components BH on the board KB. The component mounting apparatus includes a board transporting part 12 on the base 11. The board transporting part 12 transports the board KB in the horizontal direction and positions the board KB in a predetermined working position. For the sake of simplicity, hereinafter, the transport directions of the board KB transported by the board transporting part 12 are referred to as the X direction, the horizontal directions orthogonal to the X directions are referred to as the Y directions, and the vertical directions are referred to as the Z directions. In the Y directions, a direction toward the center of the base 11 is referred to as "front," and a direction toward the opposite side is referred to as "rear."

[0008] The mounting head 13 is mounted above the base 11. The mounting head 13 is moved horizontally by a head movement mechanism (not shown). The mounting head 13 includes a plurality of downward-facing component holding nozzles 14.

[0009] In Fig. 1, the carriage 15 is connected to one end of the base 11 in the Y direction. The carriage 15 includes a feed base 21 and a reel holder 22. Several tape feeders 16 are mounted side by side in the X direction on the feed base 21.

[0010] In the Fig. 2(a) and Fig. 2(b), the feeder base 21 includes a block-shaped post 31 and a wall 32 provided at a front portion of the post 31 and extending upward. The upper surface of the post 31 serves as a feeder support 33, and the rear surface of the post 31 serves as a feeder terminal surface 34.

[0011] The stand 31 is provided with fastening slots 35 in which the tape feed 16 is to be fastened side by side in the X-direction. As shown in Fig. 2(a), the single fixing slot 35 includes a pair of feed guides 41 provided side by side in the X direction in the feed support 33, two upper and lower positioning holes 42 that are through holes penetrating the wall 32 in the thickness direction (Y direction), a fixing hole 44 provided in the feed terminal surface 34, an electrical connection box 45, and an air connection box 46. In the first exemplary embodiment, the feed base 21 has a plurality of fixing slots 35 arranged side by side in the X direction.

[0012] The feed guides 41 consist of rail-shaped elements arranged side by side in the lateral directions (X directions, the directions that intersect the transport directions of the carrier tape in a horizontal plane) and extending in the front and rear directions (Y directions). Two upper and lower positioning holes 42 are provided side by side in the Z directions. The mounting hole 44, the electrical connection box 45, and the air connection box 46 are arranged in the Z direction, and the mounting hole 44 is located above the electrical connection box 45. The air connection box 46 is located between the mounting hole 44 and the electrical connection box 45.

[0013] The reel holder 22 rotatably holds the reel RL around which the carrier tape CT is wound, which is to be transported by the tape feeder 16. As shown in the Fig. 3(a) and Fig. As shown in Fig. 3(b), the carrier tape CT is provided with a large number of component receiving pockets PK arranged in a row, and a large number of feed holes KH are provided in a row at positions parallel to the row of component receiving pockets PK.

[0014] In Fig. 3(a) and Fig. 3(b), a component BH is stored in each component receiving pocket PK, and the cover tape TT is attached at a position that covers the component receiving pocket PK on top of the carrier tape CT. That is, the component BH is stored in the carrier tape CT in a state where it is covered with the cover tape TT.

[0015] [As in Fig. 3(a) and Fig. 3(b) or Fig. 4(a) and Fig. 4(b), the cover tape TT includes a guide portion SD projecting from the tip ST of the carrier tape CT. The guide portion SD may have a shape in which a tip portion of the cover tape TT projects from the tip ST of the carrier tape CT, as shown in FIGS. Fig. 3(a) and Fig. 3(b), or may have a shape in which a part of the auxiliary tape HJ attached to the cover tape TT protrudes from the tip ST of the carrier tape CT, as shown in the Fig. 4(a) and Fig. 4(b).

[0016] In the form in which a tip of the cover tape TT protrudes from the tip ST of the carrier tape CT, the guide part SD is formed from a part (a section with the length L) of the cover tape TT protruding from the tip ST of the carrier tape CT ( Fig. 3(a)). In the mold with auxiliary belt HJ, the guide part SD is formed from a part (a section with the length L) of the auxiliary belt HJ, which protrudes from the tip ST of the carrier belt CT ( Fig. 4(b)).

[0017] In the Fig. 5(a), Fig. 5(b) and Fig. 6, the tape feeder 16 includes a main body 51 detachably attached to the mounting slot 35 of the feeder base 21. Two forwardly projecting positioning pins 52 are provided at a front portion of the main body 51.

[0018] In Fig. 5(a), Fig. 5 (b) and Fig. 6, a lower extension 53 extending downward is formed at a rear portion of the main body 51 of the tape feeder 16. A fixed portion 54, a connector 55, and an air port 56 are provided at the front of the lower extension 53 so as to protrude forward.

[0019] When the tape feeder 16 is attached to the mounting slot 35, the engaging part 51K ( Fig. 6) provided at a lower part of the main body 51, is inserted between the feed guides 41 forming the mounting slot 35 ( Fig. 2(a) → Fig. 2(b)). As a result, two positioning pins 52 are inserted into the two upper and lower positioning holes 42, and the fixed part 54 is inserted into the mounting hole 44. The connector 55 is connected to the electrical connection box 45, and the air connector 56 is connected to the air connection box 46.

[0020] When the fixed part 54 is inserted into the mounting hole 44, the fixed part 54 is connected to a mounting part (not shown) provided inside the stand 31, and the tape feeder 16 is attached to the stand 31. When the connector 55 is connected to the electrical connection box 45, the tape feeder 16 is electrically connected to the stand 31 and transmits the signals. When the air connector 56 is connected to the air connection box 46, air can be supplied from the base 11 side to the tape feeder 16 side via the stand 31.

[0021] In Fig. 6, the conveying path 61 on which the carrier tape CT is transported is provided in the main body 51. The conveying path 61 includes the carrier tape introduction opening 61A at a rear end of the main body 51 and the outlet opening 61B at a front end of the main body 51. The upper surface of the conveying path 61 serves as a conveying surface 61M (see Fig. 8) to support and transport the lower surface of the carrier belt CT. That is, in the first exemplary embodiment, the conveying path 61 includes the conveying surface 61M that supports the carrier belt CT from below.

[0022] In Fig. 6, a carrier tape transport part 62 for transporting the carrier tape CT is provided in a front upper part of the main body 51. The carrier tape transport part 62 includes three pinions (introduction pinion 62A, positioning pinion 62B, and discharge pinion 62C) arranged from back to front, and the pinion drive motor 62D.

[0023] In Fig. 6, a plurality of feed pins 62P are mounted on the outer peripheral portions of the insertion pinion 62A, the positioning pinion 62B, and the discharge pinion 62C. These three pinions are rotated in the same direction by the pinion drive motor 62D via a gear mechanism (not shown). The direction in which the three pinions are rotated is the direction in which the feed pin 62P, located at the highest position of each pinion, moves forward. The operation of the pinion drive motor 62D is controlled by the controller 63 ( Fig. 6) located in the main body 51.

[0024] The carrier tape CT is drawn from the reel RL and inserted into the conveying path 61 from the carrier tape insertion opening 61A, with the side where the above-described guide part SD is located. The carrier tape CT inserted into the conveying path 61 is conveyed forward (downstream) by the three pinions (introduction pinion 62A, positioning pinion 62B, and discharge pinion 62C), that is, by the carrier tape conveying part 62, which is rotated by the pinion drive motor 62D. At this time, the carrier tape CT is fed to the introduction pinion 62A, the positioning pinion 62B, and the discharge pinion 62C in this order.

[0025] The carrier tape CT inserted from the carrier tape insertion opening 61A is conveyed to the downstream side, that is, to the carrier tape discharge opening 61B, by the carrier tape conveying part 62. From the carrier tape CT conveyed to the downstream side, the cover tape TT is peeled off before passing through the component removal opening 16K in the upper front part of the main body 51, and upon passing through the component removal opening 16K, the component BH stored in the carrier tape CT, which is covered with the cover tape TT, is exposed.

[0026] The component removal opening 16K is located between the positioning pinion 62B and the discharge pinion 62C, and the exposed components BH are intermittently positioned one after another at the component removal position 16T within the component removal opening 16K. This allows the mounting head 13 to suck and hold the component BH located in the component removal opening 16K (component removal position 16T) with the component holding nozzle 14 and remove (pick up) the component BH from the tape feeder 16. Thus, the carrier tape conveying part 62 advances the carrier tape CT along the conveying path 61 with the guide part SD of the cover tape TT and positions the component BH at the component removal position 16T.

[0027] In Fig. 6, the above-described air connector 56 provided in the lower extension 53 of the main body 51 is connected to the air ejector 65 provided in the front upper part of the main body 51 via the air line 64 provided in the lower extension 53. The air ejection control valve 66 provided in the lower extension 53 is interposed in the air line 64.

[0028] When the tape feeder 16 is attached to the feeder base 21, the air connector 56 is connected to the air connector box 46 on the feeder base 21. By controlling the air discharge control valve 66 by the control unit 63 in a state where the air connector 56 is connected to the air connector box 46, the air supplied from the feeder base 21 through the air line 64 can be discharged from the air ejector 65.

[0029] In Fig. 6 is the Fig. 7 is provided in the front upper part of the main body 51. As shown in the Fig. 8 and Fig. 9, the belt cover serves specifically to cover a part of the conveying path 61, the part being located between the positioning pinion 62B and the discharge pinion 62C from above. In the first exemplary embodiment, the belt cover 70 is composed of a plate-like member and is detachable from the main body 51.

[0030] Fig. 10 shows a state in which the band cover 70 is attached to the main body 51. As in Fig. As shown in Figure 10, the main body 51 of the belt feeder 16 includes two carrier belt supports 51S extending along the YZ plane and opposing each other in the X direction. An upper edge of the carrier belt support 51S serves as a conveying surface 61M.

[0031] As in Fig. 10, the tape cover 70 is provided at the front upper portions of the pair of carrier tape supports 51S to cover part of the upper edges (i.e., the conveying surface 61M) of the pair of carrier tape supports 51S from above. As described above, since the conveying surface 61M is formed from the upper edges of the pair of carrier tape supports 51S and both ends of the carrier tape CT are supported from below by the upper edges of the pair of carrier tape supports 51S, as the carrier tape CT, not only a type without a downward protruding part (so-called paper tape type) but also an embossed type having a downward protruding embossed part can be used.

[0032] In the Fig. 7 and Fig. 10, the tape cover 70 includes a first tape pusher 71 forming a central part thereof, a second tape pusher 72 forming a part on the upstream side with respect to the first tape pusher 71, and a third tape pusher 73 forming a part on the downstream side with respect to the first tape pusher 71. The first tape pusher 71 and the second tape pusher 72 are connected to each other by a coupling part 74. The cover tape passage 75 formed from a gap between the first tape pusher 71 and the second tape pusher 72 is formed on one side (one side of the tape cover 70 in the width directions, i.e., one side in the X directions) of the coupling part 74. The third tape pusher 73 is formed with the above-described component removal opening 16K ( Fig. 7).

[0033] In this way, in the first exemplary embodiment, the tape cover 70 covers the upper surface of the carrier tape CT conveyed by the carrier tape conveying part 62, and includes the component removal opening 16K formed at the component removal position 16T and the cover tape passage 75 consisting of a gap formed at a position away from the component removal opening 16K on the upstream side.

[0034] In Fig. 7, an upstream projecting projection piece 71H is formed at an upstream end of the first band pusher 71, and an edge of the projection piece 71H (ie, an upstream edge of the first band pusher 71) serves as a stopper 76. As will be described later, the stopper 76 functions as part of the guide 140 ( Fig. 8) which guides the guide part SD from the cover tape passage 75 upward (to the top of the tape cover 70) by stopping the feed of the guide part SD of the cover tape TT included in the carrier tape CT conveyed by the carrier tape conveying part 62.

[0035] As described above, the second tape pusher 72 is connected to the upstream side of the first tape pusher 71 through the coupling part 74. The downstream end of the second tape pusher 72 has a linear shape extending in the X direction and is positioned on the upstream side of the stopper 76, which is the upstream edge of the first tape pusher 71 and faces the stopper 76 with a predetermined gap (cover tape passage 75) therebetween.

[0036] In Fig. 11, a downstream portion of the second belt pusher 72 is a contact part 77 extending above the conveying surface 61M and parallel to the conveying surface 61M. A portion on the upstream side with respect to the contact part 77 is an inclined part 78 whose height gradually increases from the conveying surface 61M toward the upstream side. The lower surface of the inclined part 78 is a tapered surface 78M whose distance from the conveying surface 61M decreases from upstream to downstream.

[0037] In Fig. 11, in a state where the carrier tape CT is not inserted into the conveying path 61, the bottom surface of the second tape pusher 72 does not abut the conveying surface 61M, and a gap of size GP is formed between the bottom surface of the second tape pusher 72 and the conveying surface 61M. The size GP of the gap is larger than the thickness of the cover tape TT but smaller than the thickness of the carrier tape CT.

[0038] In Fig. 7, both ends in the width directions (X directions) of the third tape pusher 73 serve as downwardly bent bending parts 79. Since the bending parts 79 at both ends of the third tape pusher 73 in the width direction are formed as described above, the bending rigidity in the top-down directions is increased, and the third tape pusher hardly warps. Thus, the carrier tape CT near the component removal opening 16K can be firmly pressed against the conveying surface 61M. On the other hand, since the first tape pusher 71 connected to the upstream side of the third tape pusher 73 and the second tape pusher 72 connected to the further upstream side of the third tape pusher via the coupling part 74 do not have a bending part like the third tape pusher 73, the first tape pusher and the second tape pusher can easily warp in the upstream-down directions.

[0039] In the Fig. 7 and Fig. 10, the belt cover 70 is provided with a pinion avoidance hole 80 extending in the Y direction. The pinion avoidance hole 80 serves to prevent collision between the feed pin 62P of the positioning pinion 62B and the belt cover 70.

[0040] In the Fig. 8 and Fig. 9, the tape cover 70 is biased (pressed) from above by three biasing members (front pusher 81, middle pusher 82, and rear pusher 83) provided at the upper front part of the main body 51. The front pusher 81 functions to press a portion of the tape cover 70 on the downstream side with respect to the component removal opening 16K against the carrier tape CT on the conveying surface 61M. The middle pusher 82 functions to press a portion between the component removal opening 16K of the tape cover 70 and the cover tape passage 75 against the carrier tape CT on the conveying surface 61M. The rear pusher 83 functions to press a portion of the tape cover 70 on the upstream side with respect to the cover tape passage 75 against the carrier tape CT on the conveying surface 61M.

[0041] In the first exemplary embodiment, since the entire tape cover 70 is uniformly biased against the conveying surface 61M by the three biasing members (front pusher 81, middle pusher 82, and rear pusher 83), the carrier tape CT advances along the conveying path 61 in the front upper portion of the main body 51 including the component removal position 16T while being pressed against the conveying surface 61M with an appropriate pressing force. In this way, the positioning of the component BH at the component removal position 16T can be precisely performed, and further, the occurrence of errors in the picking up of the component BH by the mounting head 13 can be prevented.

[0042] In the Fig. 8 and Fig. 9, the front pusher 81 includes the pusher plate 81a as a first pivot lever, the base 81b, and the first coil spring 81c. The pusher plate 81a extends in the Y direction in the front upper part of the main body 51 (more specifically, in a region including the upper part of the discharge pinion 62C and the vicinity of the carrier tape discharge opening 61B), and the base 81b provided at the downstream end portion is supported by the main body 51 by a support pin 81d extending in the X direction. A first coil spring 81c is provided between the base 81b and the main body 51 and urges the base 81b in a direction that pushes the base upward with respect to the main body 51.

[0043] As in the Fig. 8 and Fig. As shown in Fig. 9, the upstream end of the pusher plate 81a abuts near the downstream end of the belt cover 70 from above. Thus, the downstream side portion (third belt pusher 73) of the belt cover 70 is biased (pressed) downward (toward the conveying surface 61M) by the first coil spring 81c via the pusher plate 81a.

[0044] In this way, the front pusher 81 in the first exemplary embodiment includes the pusher plate 81a as a first pivot lever that swings around a horizontal shaft (support pin 81d) perpendicular to the conveying directions of the carrier tape CT, and the first coil spring 81c that biases one end of the pusher plate 81a against the upper surface of the tape cover 70. The lower surface of the third tape pusher 73 abuts the conveying surface 61M when the carrier tape CT introduced into the conveying path 61 has not yet passed under the tape cover 70 (this state is referred to as the "initial state", see Fig. 8).

[0045] In the Fig. 8 and Fig. 9, the center pusher 82 includes the spring retainer 82a, the torsion spring 82b, and the pusher roller 82c. The spring retainer 82a consists of a shaft-shaped member, both ends of which are supported by the side cover 51P located on the side surface (YZ plane) of the main body 51, so that the conveying path 61 is located therebetween and extends in the X direction. The side cover 51P constitutes the main body 51.

[0046] In the Fig. 8, Fig. 9 and Fig. 12, the coiled portion of the torsion spring 82b is inserted into the spring holder 82a (in the X directions) to be held by the spring holder 82a, and of the upstream and downstream extensions, the upstream extension is locked with a pin fixed to the side cover 51P. The pusher roller 82c extends in the X direction, and its two ends are movably supported in the up-and-down direction by two side covers 51P. The pusher roller 82c is rotatable about an axis along the X direction.

[0047] The pusher roller 82c is positioned at an intermediate portion of the tape cover 70 (a portion located between the component removal opening 16K and the cover tape passage 75) and is biased downward by the downstream extension of the torsion spring 82b. In this way, the intermediate portion (first tape pusher 71) of the tape cover 70 is biased downward (toward the conveying surface 61M) by the torsion spring 82b via the pusher roller 82c (pressing force F1 in Fig. 12).

[0048] In this way, the middle pusher 82 in the first exemplary embodiment includes the pusher roller 82c as a roller pin rotatable about a horizontal axis (X-axis) intersecting the conveying directions of the carrier tape CT, and the torsion spring 82b as an elastic body that biases the pusher roller 82c against the upper surface of the tape cover 70. In the initial state in which the carrier tape CT introduced into the conveying path 61 has not yet reached under the tape cover 70, the underside of the second tape pusher 72 abuts the conveying surface 61M ( Fig. 12).

[0049] In the Fig. 8 and Fig. 9, the rear pusher 83 includes the rear pusher lever 91 as a second pivot lever and a second coil spring 92. The rear pusher lever 91 extends in the Y direction in a front upper portion of the main body 51 (more precisely, in an upper portion of the insertion pinion 62A). As shown in Fig. 12, the rear pusher lever 91 includes an intermediate portion in the Y directions supported by the lever pivot shaft 93 extending in the X directions, and includes an upstream boss 91a extending upstream of the lever pivot shaft 93 and a downstream boss 91b extending downstream.

[0050] In Fig. 12, a tip portion of the downstream extension 91b is bent downward and extended, and the push lever tip portion 91c, which is a tip portion of the bent and extended portion, is located above the second belt pusher 72. The second coil spring 92 pushes the upstream extension 91a of the rear pusher lever 91 upward, that is, in a direction away from the conveying surface 61M. Thereby, the lever tip portion 91c of the rear pusher lever 91 is biased downward, that is, toward the conveying surface 61M.

[0051] The rotation range of the rear pusher lever 91 is restricted by the pin 94 fixed to the main body 51. In the initial state in which the carrier tape CT has not yet come under the contact part 77 of the second tape pusher 72, the lever tip part 91c is located at a position separated from the upper surface of the upstream part (second tape pusher 72) of the tape cover 70 by a distance smaller than the thickness of the carrier tape CT, and the lever tip part 91c is not in contact with the second tape pusher 72. When the carrier tape CT comes under the contact part 77 of the second tape pusher 72 and the second tape pusher 72 is lifted by the carrier tape CT, the second tape pusher 72 abuts the lever tip part 91c. As a result, the second band pusher 72 is biased (pressed) downwards (carrier band CT) by the second coil spring 92 via the rear pusher lever 91 (see also Fig. 24).

[0052] In this way, the rear pusher 83 in the first exemplary embodiment includes the rear pusher lever 91 as a second pivot lever that swings around the horizontal axis (lever pivot shaft 93) orthogonal to the conveying directions of the carrier tape CT, and the second coil spring 92 that biases one end of the rear pusher lever 91 against the upper surface of the tape cover 70. The rear pusher 83, together with the middle pusher 82, pushes an upstream portion (first tape pusher 71 and second tape pusher 72) located on the upstream side with respect to the third tape pusher 73, which is a downstream portion of the tape cover 70 where the component removal opening 16K is formed.

[0053] In the Fig. 8, Fig. 9 and Fig. 12, the cover tape pulling part 101 is arranged at a position upstream of the component removal position 16T. Specifically, the cover tape pulling part is provided at a position above the tape cover 70 in the main body 51. The cover tape pulling part 101 has the function of pulling upward the cover tape TT peeled from the carrier tape CT.

[0054] In the Fig. 11 and Fig. 12, the cover tape drawing part 101 comprises the drive roller 101a and the driven roller 101b, which has a smaller diameter than the drive roller 101a and is arranged downstream of the drive roller 101a. The drive roller 101a and the driven roller 101b are in contact with each other, and when the drive roller 101a is in Fig. 11 rotates counterclockwise, the driven roller 101b is rotated clockwise by the drive roller 101a. The drive roller 101a is driven by a gear (not shown) that transmits the power of the pinion drive motor 62D. Thus, the drive roller 101a is driven at the same time as the carrier tape transport part 62.

[0055] In the Fig. 8, Fig. 9 and Fig. 12, the cover tape discharge path 102 is provided at a position upstream of the cover tape drawing part 101 in the main body 51. The cover tape TT drawn by the cover tape drawing part 101 is discharged into the discharge path 102.

[0056] In the Fig. 8, Fig. 9 and Fig. 12, a straightening device 103 is provided at a position on the upstream side of the belt cover 70 in the main body 51 (see also Fig. 11). The straightening device 103 has the function of straightening the guide part SD of the cover tape TT of the carrier tape CT, which is inserted from the carrier tape insertion opening 61A into the conveying path 61, when the guide part SD is bent upward or downward.

[0057] As in the Fig. 10 and Fig. 11, the straightening device 103 includes the pivot member 111 and the recess 112. The straightening device 103 is arranged on the upstream side with respect to the component removal position 16T and has a function of bringing the guide part SD of the cover tape TT into a state where it is directed downstream of the tip ST of the carrier tape CT, along with the movement of the carrier tape CT which is fed downstream and then returned upstream by the carrier tape conveying part 62.

[0058] In Fig. 11, the pivoting member 111 comprises a base 111a supported by a lever pivot shaft 93, which is a pivot shaft of the rear pusher lever 91, and an extension 111b extending downstream from the base 111a and having a bent and downwardly directed tip portion. When the pivoting member 111 is about to swing in a direction in which the tip of the extension 111b is lowered due to its own weight (in Fig. 11 clockwise), the pivoting element hits a vibration limiting element (not shown) and its swinging is restricted.

[0059] In a state where the pivoting of the pivoting member 111 is restricted due to its own weight (which is shown in Fig. 11, referred to as the "swing restriction state"), the edge of the lower end of the extension 111b (swing element edge 111c) is located at a position spaced upward from the conveying surface 61M by a certain distance (size gp). The size gp of the fixed distance is greater 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. In the first exemplary embodiment, the swing element edge 111c and the conveying surface 61M are separated from each other by the size gp. However, when there is no risk of the guide part SD of the cover tape TT being deformed, the swing element edge 111c can abut against the conveying surface 61M.

[0060] When the pivoting element edge 111c is moved from the pivoting restriction state into Fig. 11 is pushed upwards, the pivoting element 111 swings in a direction in which the pivoting element edge 111c is raised (in Fig. 11 counterclockwise). Then, the state in which the pivoting element edge 111c rests against the upper side of the carrier tape CT is maintained.

[0061] In the Fig. 10 and Fig. 11, the recess 112 has a curved surface 112M in which a part of the conveying surface 61M is recessed downwards. Since the conveying surface 61M, as described above, is formed by the upper edges of two carrier belt supports 51S that are opposite each other in the X direction, the recess 112 (curved surface 112M) is also formed on the upper edges of these two carrier belt supports 51S ( Fig. 10). Of the upstream and downstream edges of the recess 112, the recess edge 112E, which is the upstream edge, is located on the downstream side with respect to the pivot element edge 111c ( Fig. ).

[0062] Next, a process will be described in which the component BH is fed with the tape feeder 16. When the tape feeder 16 transports the carrier tape CT and feeds the component BH to the component removal position 16T, the operator first causes the guide part SD at the tip of the carrier tape CT to protrude according to the above-described method, and then manually inserts the tip part ST of the carrier tape CT into the carrier tape insertion opening 61A. Then, the operator pushes the carrier tape CT toward the downstream side until the feed hole KH at the tip ST of the carrier tape CT engages the feed pin 62P of the insertion pinion 62A.

[0063] When the carrier tape CT is inserted from the carrier tape insertion opening 61A, the feed hole KH near the tip ST of the carrier tape CT is engaged with the feed pin 62P of the insertion pinion 62A, which is detected by a sensor (not shown). When the sensor detects that the feed hole KH of the carrier tape CT engages with the feed pin 62P of the insertion pinion 62A, the controller 63 drives the pinion drive motor 62D to rotate the three pinions (intake pinion 62A, positioning pinion 62B, and discharge pinion 62C). Alternatively, the user may insert the carrier tape CT from the carrier tape insertion hole 61A, engage the feed hole KH with the feed pin 62P of the insertion pinion 62A, operate the tape feeder operation switch 16 to operate the pinion drive motor 62D and rotate the three pinions.Accordingly, the transport of the carrier belt CT is started by the carrier belt conveying part 62, and the carrier belt CT moves downstream on the conveying surface 61M. At this time, the belt cover 70 is still in the initial state (. Fig. 12).

[0064] As in Fig. 13, the tip ST of the carrier tape CT, which moves downstream on the conveying surface 61M, passes under the pivoting element edge 111c, which waits at a position separated from the conveying surface 61M, and further passes through the recess edge 112E. When the tip ST of the carrier tape CT reaches the position P1, which is downstream from the position S1 of the recess edge 112E by the predetermined distance D1 ( Fig. 13) is removed, the controller 63 temporarily stops the operation of the pinion drive motor 62D (ie, it temporarily stops the feeding of the carrier tape CT).

[0065] The predetermined distance D1 here is a distance that exceeds the length L of the guide part SD of the cover tape TT (D1 > L). Therefore, when the guide part SD of the cover tape TT is bent upward or downward by the carrier tape CT at the time when the rotation of the pinion drive motor 62D is stopped (and accordingly, the feeding of the carrier tape CT is stopped), the guide part tip SS (see also Fig. 3(a) and Fig. 4(b)), which is the tip of the guide part SD of the cover band TT, on the downstream side with respect to the pivot element edge 111c and the recess edge 112E ( Fig. 13). When the guide part SD of the cover tape TT is not bent upward or downward by the carrier tape CT, the guide part tip SS of the cover tape TT enters the space between the conveying surface 61M and the bottom of the contact part 77 of the second tape pusher 72 (the space of the gap with the size GP described above).

[0066] After the controller 63 temporarily stops the advance of the carrier tape CT as described above, it rotates the pinion drive motor 62D in the opposite direction. This advances (ie, retracts) the carrier tape CT to the upstream side. If the guide part SD of the cover tape TT is in an upwardly bent state at the time the carrier tape CT starts to retract, as shown in Fig. 13, the guide part tip SS of the cover band TT abuts the extension 111b of the pivot element 111 and the pivot element edge 111c from the downstream side ( Fig. 14 and Fig. 15).

[0067] When the pulling-in operation of the carrier tape CT is started, the controller 63 stops the operation of the pinion drive motor 62D when the tip ST of the carrier tape CT reaches the position P2 which is retracted downstream from the position S2 of the swing element edge 111c by the predetermined distance D2 ( Fig. ). By setting the predetermined distance D2 to a distance that is smaller than the length L of the guide part SD of the cover tape TT and greater than half the length of the guide part SD (0.5L < D2 < L), the tip ST of the carrier tape CT is located on the upstream side of the pivoting element edge 111c when the retraction operation of the carrier tape CT is stopped. In this state, the guide part SD of the cover tape TT is released from the upward bending state and extends substantially straight toward the downstream side, that is, the upward bending of the guide part SD of the cover tape TT is straightened ( Fig. 16).

[0068] In this way, in the first exemplary embodiment, a series of operations (hereinafter referred to as "switch-back operation") are performed in which the tip ST of the carrier tape CT is moved forward to the downstream side with respect to the aligning edge (here, the notch edge 112E) by the predetermined distance D1 (from the notch edge 112E to the downstream position separated by a distance greater than the length L of the guide part SD), and then the carrier tape CT is moved (retracted) to the upstream position in which the tip ST is separated from the aligning edge (pivot edge 111c) by a predetermined distance D2, which is smaller than the length L of the guide part SD and greater than half the length L of the guide part SD. When the guide part SD of the cover tape TT is in an upwardly bent state, this state can be resolved by this switch-back operation.

[0069] In this way, the straightening device 103 in the first exemplary embodiment includes the pivoting element 111, which is arranged on the upper side of the conveying surface 61M and has the pivoting element edge 111c at the lower end as an alignment edge. The pivoting element edge 111c of the pivoting element 111 waits for the tip of the carrier tape CT to move from the upstream side at a position spaced upward from the conveying surface 61M.

[0070] When the guide part SD of the cover tape TT of the carrier tape CT inserted into the carrier tape insertion opening 61A is bent downward toward the bottom of the carrier tape CT, the guide part tip SS of the cover tape TT is caught by the upstream edge (recess edge 112E) of the recess 112 in the switch-back operation ( Fig. 17). In a state where the downshift operation is completed and the tip ST of the carrier tape CT is positioned on the upstream side with respect to the swing element edge 111c ( Fig. 16), the downward bend of the guide part SD of the cover strip TT is eliminated, and the guide part SD extends substantially straight to the downstream side, ie the downward bend of the guide part SD of the cover strip TT is straightened ( Fig. 16).

[0071] In this way, in the first exemplary embodiment, the recess 112 formed on the conveying surface and the recess edge 112E of the upstream edge of the recess 112 serve as part of the straightening device 103.

[0072] When the upward or downward bending of the cover tape TT is caused by the switching back of the carrier tape CT ( Fig. 16), the controller 63 drives the pinion drive motor 62D to rotate the three pinions in the direction in which the carrier tape CT advances toward the downstream side. As a result, the tip portion ST of the carrier tape CT passes the pivoting element edge 111c toward the downstream side, and the guide portion SS of the cover tape TT, which extends toward the downstream side, enters under the inclined portion 78 of the second tape pusher 72 of the tape cover 70 ( Fig. ). In addition, the guide part tip SS of the cover belt TT enters a space between the second belt pusher 72 and the conveying surface 61M (a space with a gap of size GP) ( Fig. 19).

[0073] Here, when the guide part SD of the cover tape TT which has been straightened by the straightening device 103 in a state of downstream extension (or the guide part SD of the cover tape TT which has not been bent upward or downward from the carrier tape CT from the beginning when the cover tape TT is inserted from the carrier tape insertion opening 61A) is slightly curved upward before entering the space between the contact part 77 of the second tape pusher 72 and the conveying surface 61M (the space of the gap with the size GP) (refer to the guide part indicated by reference symbol “SD1” in Fig. 18), the guide part tip SS moves to the downstream side and follows the tapered surface 78M of the second tape pusher 72. In this way, the guide part SD of the cover tape TT, which has been aligned by the pivoting element edge 111c and the recessed edge 112E, is prevented from being bent upward again. In this way, the lower surface (tapered surface 78M) of the inclined part 78 of the second tape pusher 72 serves as an upper bending prevention surface that prevents the upper bending of the cover tape TT.

[0074] If the guide part SD of the cover belt TT is slightly bent downwards before entering the space between the second belt pusher 72 and the conveying surface 61M (see the guide part shown in Fig. designated by reference symbol "SD2"), the guide part tip SS follows the curved surface 112M of the recess 112 and moves toward the downstream side. Thus, the guide part SD of the cover tape TT, once aligned by the edge of the pivot member 111c and the recess edge 112E, is prevented from bending downward again. Thus, the surface (curved surface 112M) of the recess 112 serves as a downward bending prevention surface, preventing the downward bending of the cover tape TT, in which the cover tape TT is bent toward the underside of the carrier tape CT.

[0075] The guide part SD of the cover belt TT, which has entered the space (the gap with the size GP) between the contact part 77 of the second belt pusher 72 and the conveying surface 61M, abuts against the stopper 76 abutting against the conveying surface 61M and is stopped by the stopper, thereby preventing the guide part SD from advancing further to the downstream side ( Fig. ). When the carrier tape CT is further conveyed to the downstream side, the leading part tip SS of the cover tape TT emerges upward through the cover tape passage 75 and projects on the upstream side of the second tape pusher 72 (ie, on the upstream side of the tape cover 70) ( Fig. 21).

[0076] In this way, the stopper 76 of the first tape pusher 71 functions to prevent the leading part tip SS of the cover tape TT, which has advanced from the upstream side, from penetrating between the first tape pusher 71 and the conveying surface 61M when the first tape pusher 71 abuts the conveying surface 61M. In the first exemplary embodiment, the first tape pusher 71 includes a stopper 76 positioned on the downstream side of the second tape pusher 72 and arranged on the conveying surface 61M, and serves as a carrier tape pusher that presses the carrier tape CT onto the conveying surface 61M.

[0077] The controller 63 controls the air discharge control valve 66 at the time (or immediately before) when the leading part tip SS of the cover tape TT reaches the cover tape passage 75 of the tape cover 70, as described above, to discharge air 107 upward from the air ejector 65 ( Fig. 21). The air ejector 65 is located at a position where the air 107 flows from below through the cover tape passage 75.

[0078] When the air 107 is discharged from the air ejector 65 at the time when the leading part tip SS of the cover tape TT reaches the cover tape passage 75, the leading part tip SS of the cover tape TT penetrates upward through the cover tape passage 75 and protrudes upward from the tape cover 70 while being guided by the flow of the air 107 discharged from the air ejector 65. As the carrier tape CT moves toward the downstream side, the leading part tip moves upward and reaches a position between the drive roller 101a and the driven roller 101b, which form the cover tape pulling part 101 ( Fig. ).

[0079] In this way, the air ejector 65 in the first exemplary embodiment serves as an auxiliary part that assists the movement of the guide part SD toward the cover tape pulling part 101 with the aid of the air flow (ie, the gas). In the first exemplary embodiment, the first tape pusher 71 as the first carrier tape pusher with the stopper 76 and the air ejector 65 as an auxiliary part form the guide 140 that guides the guide part SD toward the cover tape pulling part 101.

[0080] The guide part tip SS of the cover tape TT, which has reached a section between the drive roller 101a and the driven roller 101b, is caught by the cover tape pulling part 101 (due to the mutual rotation of the drive roller 101a and the driven roller 101b) and pulled upwards ( Fig. 23).

[0081] When the guide part SD of the cover tape TT has passed upward through the cover tape passage 75 as described above, the tip ST of the carrier tape CT abuts the beveled surface 78M of the second tape pusher 72 ( Fig. ). When the carrier tape CT, whose tip ST abuts the tapered surface 78M, advances further to the downstream side, the second tape pusher 72 is pushed upward by the carrier tape CT ( Fig. 21 → Fig. 22).

[0082] The second belt pusher 72, which is pushed upwards by the carrier belt CT, pulls the first belt pusher 71 upwards via the coupling part 74. This creates a gap with the distance G ( Fig. 22), in which the carrier tape CT can move forward, and the stopper 76, which is an upstream edge of the first carrier tape pusher 71, also moves upward from the conveying surface 61M. When the gap with the distance G is formed between the first tape pusher 71 and the conveying surface 61M, the carrier tape CT moves in the gap to the downstream side ( Fig. 22 → Fig. 23).

[0083] In this way, the second tape pusher 72 is a contact displacement part that comes into contact with and is displaced by the carrier tape CT, and the coupling part 74 is a transmission part that transmits the displacement of the second tape pusher 72 as a contact displacement part to the first tape pusher 71 to displace the stopper 76. The second tape pusher 72 as a contact displacement part and the coupling part 74 as a transmission part form the height change part 70T ( Fig. 7), which lifts the stop 76 upwards from the conveying surface 61M.

[0084] When the second tape pusher 72 is pushed upward by the carrier tape CT as described above, the inclined part 78 of the second tape pusher 72 abuts the pusher lever tip part 91c of the rear pusher 83 from below and pushes the pusher lever tip part 91c upward. As a result, the second coil spring 92 of the rear pusher 83 is compressed by the upstream extension 91a of the rear pusher lever 91 and pushes the upstream extension 91a upward as a compression reaction force. As a result, the second tape pusher 72 (inclined part 78) is biased downward by the second coil spring 92 via the rear pusher lever 91 (pressing force F2 in Fig. 24).

[0085] In this way, in the first exemplary embodiment, the rear pusher 83 is configured so that the rear pusher lever 91 does not contact the tape cover 70 in a state where the carrier tape CT is not on the conveyance path 61, and when the rear pusher lever comes into contact with the tape cover 70 (specifically, the second tape pusher 72) that is shifted upward by the carrier tape CT, the rear pusher pushes the tape cover 70 downward.

[0086] When the carrier tape CT moves to the downstream side in the gap formed between the underside of the first tape pusher 71 and the conveying surface 61M, the cover tape TT, which passes through the cover tape passage 75 and extends upward, is further pulled upward (into the cover tape discharge path 102) by the cover tape pulling part 101 ( Fig. 25).

[0087] In this way, the cover tape drawing part 101 in the first exemplary embodiment draws in the cover tape TT peeled off from the carrier tape CT.

[0088] In the first exemplary embodiment, the tape cover 70 and the cover tape pulling part 101 form the cover tape pulling part 120 ( Fig. 8) (see also Fig. 6 and Fig. 11). Here, the cover tape peeling part 120 refers to a functional part that is arranged downstream of the straightening device 103 and upstream of the component removal position 16T, and peels the cover tape TT from the top surface of the carrier tape CT fed downstream by the carrier tape conveying part 62 by gripping and pulling in the guide part SD of the cover tape TT extending downstream from the tip ST of the carrier tape CT.

[0089] The carrier tape CT, from which the cover tape TT has been peeled off by the cover tape peeling part 120, is conveyed downstream on the conveying path 61 by the carrier tape conveying part 62, and the first component receiving pocket PK in the carrier tape CT is positioned at the component removal position 16T. This completes the step of positioning the carrier tape CT. The carrier tape conveying part 62 continuously performs the process (carrier tape CT positioning step) of positioning the first component receiving pocket PK of the carrier tape CT from the position P2 to the component removal position 16T.

[0090] In the carrier tape CT, the cover tape TT is peeled off by the cover tape peeling part 120 during positioning of the carrier tape CT. Then, the carrier tape conveying part 62 performs a pitch feed along with the process in which the mounting head 13 included in the component mounter 1 sucks and removes the component BH (pick-up process), and the component pick-up pocket PK is sequentially positioned at the component removal position 16T (carrier tape positioning process).

[0091] In this way, in the first exemplary embodiment, the tape feeder 16 serving as a component feeding device is configured to peel the cover tape TT from the carrier tape CT with the guide part SD projecting from the tip of the carrier tape CT, expose the component BH stored on the carrier tape CT in a state covered with the cover tape TT, convey the exposed component BH to the component removal position 16T, and feed the component BH to the component mounting device 1.

[0092] When the component mounting apparatus 1 including the tape feeder 16 having the above configuration performs component mounting work in which the component BH is mounted on the board KB, first, the board KB, which is fed from outside the component mounting apparatus 1, is carried in by the board transporting part 12 and positioned at a predetermined work position. When the board KB is positioned at the work position, each tape feeder 16 feeds the component BH to the component removal opening 16K, and the mounting head 13 holds and pulls out the component BH at the component removal position 16T of the tape feeder 16 with the component holding nozzle 14. The mounting head 13, which has taken out the component BH from the component removal position 16T of the tape feeder 16, moves over the board KB and mounts the component BH at a target position specified on the board KB.When all components BH to be mounted on the plate KB are mounted, the plate transport part 12 conveys the component KB to the outside of the component mounting device 1. The component mounting work on the individual plate KB is thus completed.

[0093] As described above, the tape feeder 16 according to the first exemplary embodiment transports the carrier tape CT along the conveying path 61 with the guide part SD of the cover tape TT in front and returns the downstream-guided carrier tape CT to the upstream side, so that the bent state of the guide part SD can be straightened by the straightening device 103. Therefore, even if the guide part SD of the cover tape TT is bent, the guide part SD can be reliably grasped by the cover tape pulling part 101.

[0094] The tape feeder 16 according to the first exemplary embodiment includes a guide 140 that guides the guide portion SD to the cover tape pulling portion 101, and the guide portion SD of the cover tape TT is stopped and guided by the stopper 76. Thus, the guide portion SD of the cover tape TT can be reliably guided and gripped by the cover tape pulling portion 101. After the guide portion SD of the cover tape TT is gripped by the cover tape pulling portion 101, the stopper 76 is lifted upward by the height changing portion 70T. Thus, the carrier tape CT can continue to travel on the conveying path 61 without being gripped by the stopper 76, and the transport of the carrier tape CT is not blocked. The guide 140 in the tape feeder 16 according to the first exemplary embodiment includes a carrier tape pusher (first tape pusher 72) that presses the carrier tape CT onto the conveying surface 61M downstream of the contact shifting part (second tape pusher 71).

[0095] In the tape feeder 16 according to the first exemplary embodiment, a part of the tape cover 70 including the component removal opening 16K and the cover tape passage 75 on the downstream side with respect to the component removal opening 16K is pressed by the front pusher 81, a part located between the component removal opening 16K and the cover tape passage 75 is pressed by the middle pusher 82, a part on the upstream side with respect to the cover tape passage 75 is pressed by the rear pusher 83, and the entire tape cover 70 is pressed against the conveying path 61 with appropriate balance. In this way, the carrier tape CT can be stably conveyed in the area including the vicinity of the component removal position 16T, and the removal accuracy of the component BH can be improved. (Second exemplary embodiment)

[0096] Fig. Figure 26 shows a portion of a tape feeder according to a second exemplary embodiment. The tape feeder according to the second exemplary embodiment is the same as the tape feeder 16 according to the first exemplary embodiment, except that the straightening device is only the alignment edge facing the top side of the carrier tape CT (pivot element edge 111c in the first exemplary embodiment).

[0097] The second exemplary embodiment differs from the first exemplary embodiment in that the straightening device 103 does not include a recess 112. This configuration can be adopted when the guide part SD of the cover tape TT of the carrier tape CT inserted from the carrier tape insertion opening 61A cannot bend downward, that is, when the guide part SD of the cover tape TT is bent upward in advance when the carrier tape CT is inserted from the carrier tape insertion opening 61A, that is, when the carrier tape CT is inserted into the carrier tape insertion opening 61A in a state where the guide part SD is bent upward. Since the straightening device 103 includes an alignment edge, the same effect as that of the tape feeder 16 in the first exemplary embodiment can be achieved in the second exemplary embodiment as well. (Third exemplary embodiment)

[0098] Fig. Figure 27 shows a portion of a tape feeder according to a third exemplary embodiment. The tape feeder according to the third exemplary embodiment is the same as the tape feeder 16 according to the first exemplary embodiment, except that the alignment edge is only the edge of the recess 112 formed on the conveying surface 61M.

[0099] The third exemplary embodiment differs from the first exemplary embodiment in that the straightening device 103 does not include a pivot member 111. This configuration can be adopted when the guide part SD of the cover tape TT of the carrier tape CT inserted from the carrier tape insertion opening 61A cannot bend upward, that is, when the guide part SD of the cover tape TT is bent downward in advance when the carrier tape CT is inserted from the carrier tape insertion opening 61A, that is, when the carrier tape CT is inserted into the carrier tape insertion opening 61A in a state where the guide part SD is bent downward. Since the straightening device 103 includes an alignment edge, the same effect as that of the tape feeder 16 in the first exemplary embodiment can be achieved in the third exemplary embodiment as well. (Fourth exemplary embodiment)

[0100] Fig. 28 shows a portion of a tape feeder according to a fourth exemplary embodiment. The tape feeder according to the fourth exemplary embodiment is the same as the tape feeder 16 according to the first exemplary embodiment, except that the tape feeder according to the fourth exemplary embodiment does not include the air ejector 65 in the first exemplary embodiment. Instead, a duct 130 covering the cover tape discharge path 102 and a suction part 131 sucking in the air 107 in the duct 130 are provided. The guide 140 of the fourth exemplary embodiment includes the first tape pusher 71 and the suction part 131.

[0101] In the fourth exemplary embodiment, the air 107 in the channel 130 is sucked in by the suction part 131 located on the upper side of the conveying surface 61M. In this way, the leading part SD of the cover tape TT is reliably drawn into the cover tape drawing part 101 through the cover tape passage 75 without the air ejector 65 in the first exemplary embodiment. That is, in the fourth exemplary embodiment, the suction part 131, similar to the above-described air ejector 65, serves as an auxiliary part that assists the movement of the leading part SD toward the cover tape drawing part 101 with the aid of the gas flow. Similar to the air ejector 65, the suction part 131 also has the function of guiding the leading part tip SS of the cover tape TT toward the cover tape drawing part 101. Thus, the same effect as that of the tape feeder 16 in the first exemplary embodiment can be achieved in the fourth exemplary embodiment. (Fifth exemplary embodiment)

[0102] Fig. 29 shows a portion of a tape feeder according to a fifth exemplary embodiment. The tape feeder according to the fifth exemplary embodiment is the same as the tape feeder 16 according to the first exemplary embodiment, except that the tape feeder according to the fifth exemplary embodiment does not include the air ejector 65 in the first exemplary embodiment, and instead, a guide member 132 is provided on the downstream side above the cover tape passage 75. The shape of the stopper 76 is changed so that it does not stop the advancement of the guide part SD of the cover tape TT, but facilitates the guide part SD to move upward from the cover tape passage 75. The guide 140 of the fifth exemplary embodiment includes the first tape pusher 71 and the guide member 132.

[0103] In the fifth exemplary embodiment, the guide part SD, which abuts against the stopper 76, changes its movement direction upward and protrudes upward from the tape cover 70 through the cover tape passage 75. The guide part SD of the cover tape TT, which is moved upward by the tape cover 70, is guided by the guide member 132 to the cover tape pulling part 101. In this way, the guide part SD of the cover tape TT is reliably gripped by the cover tape pulling part 101, and the same effect as in the tape feeder 16 according to the first exemplary embodiment can be achieved. (Sixth exemplary embodiment)

[0104] Fig.30 shows a portion of a tape feeder according to a sixth exemplary embodiment. The tape feeder according to the sixth exemplary embodiment is the same as the tape feeder 16 according to the first exemplary embodiment, except that the tape feeder according to the sixth exemplary embodiment does not include the air ejector 65, and the shape of the stopper 76 of the tape cover 70 (specifically, the height from the conveying surface 61M), the size and arrangement of the drive roller 101a and the driven roller 101b constituting the cover tape pulling part 101, and the like are different from those of the first exemplary embodiment. The shape of the stopper 76 is changed so that it does not stop the feeding of the guide part SD of the cover tape TT, but facilitates the guide part SD to move upward from the cover tape passage 75. The guide 140 of the sixth exemplary embodiment consists only of the first tape pusher 71.

[0105] In the sixth exemplary embodiment, the guide part SD of the cover tape TT, which protrudes upward from the tape cover 70 through the cover tape passage 75, can be guided to the cover tape drawing part 101 without requiring any auxiliary part (air ejector 65, suction part 131, guide member 132, and the like). Thus, the same effect as that of the tape feeder 16 in the first exemplary embodiment can be achieved in the sixth exemplary embodiment.

[0106] As described above, the component feeding device (tape feeding device 16) according to the first to sixth exemplary embodiments includes a guide having a stopper 76 disposed on the conveying surface 61M and guiding the guide portion SD toward the cover tape pulling portion 101. The guide portion SD of the cover tape TT is stopped by the stopper 76 and guided by the guide. Thus, the cover tape TT can be reliably peeled off from the carrier tape CT. After the guide portion SD of the cover tape TT is gripped by the cover tape pulling portion 101, the stopper 76 is lifted upward by the height changing portion 70T. Thus, the carrier tape CT can continue to travel on the conveying path 61 without being gripped by the stopper 76, and the transportation of the carrier tape CT is not blocked.

[0107] Although the exemplary embodiments of the present invention have been described above, the present invention is not limited to the above exemplary embodiments, and various changes and the like may be made. For example, as in the first, second, and fourth to sixth exemplary embodiments described above, when the pivot member 111 is in the pivot restriction state, the feed of the carrier tape CT may be awaited with the edge of the pivot member 111c abutting against the conveying surface 61M, instead of the configuration in which the feed of the carrier tape CT is awaited with the edge of the pivot member 111c separated from the conveying path 61. In this case, the conveying surface 61M may be configured to function like a pivot restriction member in the first exemplary embodiment. Industrial applicability
