Description

Technical Field

[0001] The present invention relates to a component supply device that conveys a carrier tape having a cover tape attached to a base tape storing components and supplies the components to a component removal position. Background Art

[0002] Conventionally, there is a known component supply device that conveys a carrier tape having a cover tape attached to a base tape containing components to supply components to a component removal position, and is generally referred to as a tape feeder. The tape feeder has a structure in which a conveying mechanism for conveying the carrier tape is provided on a frame forming a conveying path for the carrier tape, and is structured so that the cover tape is peeled off from the base tape before the carrier tape traveling on the conveying path reaches the component removal position, thereby enabling the components to be removed from the component removal position.

[0003] In this type of tape feeder, in addition to a manual tape setting type tape feeder in which an operator manually peels the cover tape from the base tape and then sets the carrier tape on the conveying path, there is also known an automatic tape setting type tape feeder in which the initial peeling of the cover tape is automatically performed (for example, refer to the following patent document 1). Regardless of the manual tape setting type or the automatic tape setting type, the cover tape peeled from the base tape is guided in a direction opposite to the conveying direction of the carrier tape while being clamped by a plurality of rollers prepared for cover tape discharge, and is fed to a cover tape discharge path formed in a frame.

In addition, the direction toward the center side of the base 11 in the Y direction is referred to as "front", and the direction toward the opposite side thereof is referred to as "rear".

[0061] exist Figure 1 In the embodiment, 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 includes a plurality of nozzles 14 extending downward.

[0062] 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 15a and a reel holding portion 15b. The tape feeder 16 is freely attachable to and detachable from the feeder base 15a, and a plurality of tape feeders 16 are arranged in the X direction on the feeder base 15a. The reel RL on which the carrier tape CT carried by the tape feeder 16 is wound is rotatably held on the reel holding portion 15b.

[0063] First, the carrier tape CT is described. Figure 2 As shown in (a) and (b) of the drawings, a plurality of component storage pockets PK are arranged in a row on the carrier tape CT, and a plurality of feed holes KH are arranged in a row at positions parallel to the row of the pockets PK.

[0064] exist Figure 2 In (a) and (b), each concave pocket PK contains one component BH, and a cover tape TT is attached to the position covering the concave pocket PK on the upper surface of the carrier tape CT. That is, the component BH is contained in the carrier tape CT in a state covered by the cover tape TT.

[0065] like Figure 2 As shown in (a), the leading end of the cover tape TT is processed to extend longer than the leading end of the base tape BT by a certain length L. Hereinafter, the portion of the cover tape TT extending longer than the leading end of the base tape BT by the length L is referred to as the "extended portion SD" ( Figure 2 (a), (b)).

[0066] exist Figure 3 In the embodiment, the tape feeder 16 is constituted as a base by a frame 21 which is loaded and unloaded relative to the feeder base 15a, and a conveying path 21L is formed in the frame 21 along the Y direction as a conveying path for the carrier tape CT. A tape inlet 21A is formed at the rear end of the frame 21 as an entrance of the conveying path 21L, and a tape outlet 21B is formed at the front end of the frame 21 as an exit of the conveying path 21L. The leading end of the carrier tape CT pulled out from the reel RL is inserted into the tape inlet 21A. In one example, the frame 21 may also be constituted by a metal block formed by die casting or cutting and a plurality of side plates covering both sides of the metal block.

[0067] A conveying mechanism 22 is provided in the frame 21 to convey the carrier tape CT inserted from the tape inlet 21A along the conveying path 21L. Figure 3 As shown in FIG. 1 , the conveying mechanism 22 includes three sprockets (introduction sprocket 22A, positioning sprocket 22B, and discharge sprocket 22C) arranged from the rear to the front and a sprocket drive motor 22D. The sprocket drive motor 22D is provided in the control unit 23 ( Figure 3 ) is controlled to work, and with the help of a gear mechanism (not shown) the three sprockets are moved in the same direction ( Figure 3 clockwise in the direction of rotation).

[0068] exist Figure 3 In the embodiment, a plurality of feed pins 22P are provided on the outer periphery of each of the three sprockets (the introduction sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C). When the three sprockets are rotated by the sprocket drive motor 22D, the feed pins 22P of each sprocket engage with the feed holes KH provided in the carrier tape CT from below, so that the carrier tape CT on the conveying path 21L moves toward the tape outlet 21B side. At this time, the carrier tape CT is transferred in the order of the introduction sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C. In this way, the conveying mechanism 22 conveys the carrier tape CT in the Y direction along the conveying path 21L.

[0069] exist Figure 3 as well as Figure 4 In the embodiment, a belt cover 24 is detachably mounted on the upper portion of the frame 21. The belt cover 24 covers the portion of the conveyance path 21L between the positioning sprocket 22B and the discharge sprocket 22C from above.

[0070] like Figure 5 As shown, the belt cover 24 is composed of a plate-like member, and the lower surface of the belt cover 24 has a shape along the upper surface of the conveying path 21L. The end of the rear end side of the belt cover 24 is an inclined portion 24S having a shape that is inclined in a manner that gradually moves away from the conveying path 21L toward the rear (upstream side).

[0071] exist Figure 3 , Figure 4 as well as Figure 5 In the embodiment, a component removal position 16T is set between the positioning sprocket 22B and the discharge sprocket 22C on the conveying path 21L. The component removal position 16T is a position where the mounting head 13 removes the component BH from the carrier tape CT using the nozzle 14. A component removal opening 24K ( Figure 5 ).

[0072] As described later, the cover tape TT is peeled off before the carrier tape CT reaches the component extraction opening 24K. Therefore, the concave pocket PK located at the component extraction position 16T is exposed upward from just below the component extraction opening 24K by the conveying action of the carrier tape CT by the conveying mechanism 22, and the mounting head 13 (nozzle 14) can extract the component BH through the component extraction opening 24K at the component extraction position 16T.

[0073] exist Figure 4 as well as Figure 5In the embodiment, a cover tape pull-out opening 24G is provided slightly behind (upstream of) the component removal opening 24K of the tape cover 24. The cover tape pull-out opening 24G is an opening for pulling the cover tape TT peeled off from the base tape BT by manual operation toward the top of the tape cover 24 when the tape feeder 16 is used as a manual tape setting type as described later.

[0074] exist Figure 5 In the embodiment, a sprocket avoidance hole 24H is provided at a position on the side of the cover tape pull-out opening 24G in the tape cover 24. The sprocket avoidance hole 24H is composed of a long hole extending in the longitudinal direction (Y direction) of the tape cover 24. The sprocket avoidance hole 24H is provided to prevent the feed pin 22P of the positioning sprocket 22B from interfering with the tape cover 24.

[0075] exist Figure 5 In the embodiment, a cover tape passage 24T is provided at a rearward position of the middle portion in the longitudinal direction (Y direction) of the tape cover 24. The cover tape passage 24T is composed of a slit extending in the width direction (X direction) of the tape cover 24.

[0076] exist Figure 3 , Figure 4 as well as Figure 6 ( Figure 6 yes Figure 4 In the enlarged view of the area RY in FIG. 2 , an air ejection unit 25 and three rollers (a first roller 26, a second roller 27, and a third roller 28) are provided in the frame 21. The air ejection unit 25 is provided at a position below the cover tape passage 24T, and ejects air 25A from below the tape cover 24 toward the cover tape passage 24T.

[0077] exist Figure 6 In the embodiment, the first roller 26, the second roller 27 and the third roller 28 are arranged above the cover tape passage 24T. These three rollers are all composed of gears in this embodiment. The second roller 27 and the third roller 28 are smaller in diameter than the first roller 26, and are respectively engaged with the first roller 26. The second roller 27 is located on the downstream side of the first roller 26, and the third roller 28 is located above the first roller 26 (on the upstream side of the second roller 27).

[0078] The first roller 26 is driven to rotate by a transmission gear mechanism (not shown) that transmits power from the sprocket drive motor 22D. Therefore, the first roller 26 and the second roller 27 and the third roller 28 meshing with the first roller 26 move in conjunction with the movement of the three sprockets (the introduction sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C) that transport the carrier tape CT.

[0079] The first roller 26 is Figure 6 The second roller 27 is driven to rotate in the counterclockwise direction (arrow R1 shown in the figure) of the first roller 26. The second roller 27 passes through the first roller 26 in the opposite direction to the first roller 26, that is, Figure 6The third roller 28 is also rotated in the clockwise direction (arrow R2 shown in the figure) of the first roller 26 through the first roller 26 in the same manner (arrow R3 shown in the figure) in the opposite direction to the first roller 26. Thus, in this embodiment, the second roller 27 and the third roller 28 rotate in the opposite direction to the first roller 26.

[0080] exist Figure 3 , Figure 4 as well as Figure 6 In the embodiment, a roller support body 31 is provided at an upper portion of a middle portion in the longitudinal direction (Y direction) of the frame 21. The roller support body 31 is composed of a block-shaped member extending in the Y direction as a whole.

[0081] The roller support body 31 is mounted on the frame 21 using a swing shaft 32 extending in the width direction (X direction) of the frame 21 at one end (rear end) and swings around the swing shaft 32, so that it can move (open and close) freely relative to the frame 21. Specifically, the roller support body 31 is in a closed position (closed position) in which the front end portion, which is the end portion on the opposite side to the rear end portion mounted on the frame 21, is located in front of the swing shaft 32 and is closed relative to the frame 21 (closed position). Figure 7 ) and the front end portion is located obliquely in front of the swing shaft 32 and is in an open position (open position) with respect to the frame 21 Figure 8 ) can be moved (opened and closed) freely.

[0082] Thus, in this embodiment, the roller support body 31 supporting the third roller 28 can move freely between a closed position (first position) in which it is closed relative to the frame 21 and an open position (second position) in which it is open relative to the frame 21, and the roller support body 31 is mounted on the frame 21 at one end (rear end) by means of a swing shaft 32 and swings around the swing shaft 32, thereby moving between the closed position (first position) and the open position (second position).

[0083] The first roller 26 and the second roller 27 of the first roller 26, the second roller 27, and the third roller 28 are respectively mounted on the frame 21. On the other hand, the third roller 28 is mounted on the roller support body 31. When the roller support body 31 is in the closed position (first position), the third roller 28 is engaged with (contacted with) the first roller 26 ( Figure 6 as well as Figure 7 ), the third roller 28 is separated from the first roller 26 when the roller support body 31 is located in the open position (second position) ( Figure 8 ).

[0084] exist Figure 7 as well as Figure 8In the embodiment, a long hole 33 is provided at the rear end of the roller support body 31, which penetrates the roller support body 31 in the width direction (X direction) and extends in the length direction (Y direction), and the swing shaft 32 extends through the long hole 33. Therefore, the roller support body 31 can move (slide) along the long hole 33 as a whole. Figure 6 as well as Figure 7 In the embodiment, a wall portion 34 is formed inside the roller support body 31 , and an urging spring 35 composed of a compression spring is provided between the wall portion 34 and the swing shaft 32 .

[0085] exist Figure 6 In the embodiment, when the roller support body 31 is in the closed position, the entire roller support body 31 is urged forward by the urging spring 35, so that the third roller 28 is pressed against the first roller 26. That is, in the present embodiment, the urging spring 35 serves as an urging mechanism that urges the third roller 28 in the direction of pressing the first roller 26 when the roller support body 31 is in the closed position.

[0086] exist Figure 6 , Figure 7 as well as Figure 8 In the embodiment, a pair of protrusions 36 protruding outward in the left-right direction are provided on both sides of the front portion of the roller support body 31 in the left-right direction (X direction). The pair of protrusions 36 extend on the same axis as the rotation axis of the third roller 28 in this embodiment.

[0087] like Figure 6 , Figure 7 as well as Figure 8 As shown in FIG. 1 , hook-shaped engagement grooves 21M that are open toward the rear are formed at the left and right portions of the upper middle portion in the longitudinal direction (Y direction) of the frame 21. When the roller support body 31 is in the closed position, the left and right protrusions 36 of the roller support body 31 enter the left and right engagement grooves 21M provided in the frame 21 from the rear and engage with the engagement grooves 21M ( Figure 6 as well as Figure 7 In this state, the entire roller support body 31 is urged forward by the urging spring 35, and the left and right protrusions 36 engage with the left and right engagement grooves 21M, so that the roller support body 31 is locked in the closed position.

[0088] Thus, in this embodiment, when the roller support body 31 is located at the closed position (first position), the roller support body 31 receives the biasing force of the biasing spring 35 in the direction of pressing the third roller 28 against the first roller 26 and is locked to the frame 21 .

[0089] In order to move the roller support body 31 in the closed position to the open position, first, the roller support body 31 is pressed backward (ie, toward the swing shaft 32) by fingers. Under the action of this pressing, the roller support body 31 moves backward as a whole while compressing the biasing spring 35 ( Fig. 9 (a) → Fig. 9 (b)), the left and right protrusions 36 of the roller support body 31 are disengaged from the left and right engagement grooves 21M formed in the frame 21 ( Fig. 9 (b)).

[0090] After the left and right protrusions 36 are disengaged from the left and right engaging grooves 21M, the roller support body 31 is unlocked relative to the frame 21. And, in this state, when the front end of the roller support body 31 is pushed upward and rearward with fingers ( Fig. 9 (b) → Fig. 9 (c)), the roller support body 31 swings around the swing shaft 32 and becomes in the open position ( Fig. 9 (c)).

[0091] Thus, in this embodiment, when the roller support body 31 is located at the closed position (first position), when the third roller 28 moves away from the first roller 26 against the biasing force of the biasing spring 35, the roller support body 31 is unlocked from the frame 21.

[0092] In order to move the roller support body 31 in the open position to the closed position, first, the roller support body 31 is pressed toward one side of the swing shaft 32 with a finger, and in this state, the roller support body 31 is moved in a direction in which the front end portion of the roller support body 31 is lowered ( Fig. 9 (c) → Fig. 9 (b)). Thus, after the left and right protrusions 36 are located behind the left and right engaging grooves 21M, the finger is released from the roller support body 31. When the finger is released from the roller support body 31, the roller support body 31 is urged forward by the urging spring 35 as a whole ( Fig. 9 (b) → Fig. 9 (a)), so the left and right protrusions 36 engage with the left and right engagement grooves 21M from the rear, and the roller support body 31 is located in the closed position and becomes locked in the frame 21 ( Fig. 9 (a)).

[0093] exist Figure 7 , Figure 8 as well as Fig.10 In the embodiment, a guide portion 41 is provided on the downstream side of the first roller 26. Fig.10 As shown, the surface of the guide portion 41 on the first roller 26 side (guide surface 41M) extends in an arc shape along the outer peripheral surface of the front side of the first roller 26 (see also Fig. 9 (a), (b), (c)).

[0094] exist Figure 4 , Figure 6 as well as Fig.10In the embodiment, a partitioning member 42 is provided between the conveying path 21L and the roller support body 31. The partitioning member 42 has a shape extending in the front-rear direction (Y direction) of the frame 21, and partitions the space between the conveying path 21L and the roller support body 31 in the frame 21 up and down. The meshing portion where the first roller 26 and the third roller 28 mesh faces the downstream side of the space formed between the partitioning member 42 and the roller support body 31 in the closed position, and the downstream side becomes the cover tape discharge path 21J for discharging the cover tape TT.

[0095] Next, the feeding operation of the component BH by the tape feeder 16 based on the automatic tape setting will be described. When the tape feeder 16 is used to feed the component BH, first, the operator forms the extension portion SD of the cover tape TT at the leading end of the carrier tape CT. After forming the extension portion SD of the cover tape TT, the operator inserts the leading end of the carrier tape CT into the tape inlet 21A. Then, the carrier tape CT is pressed toward the downstream side until the feed hole KH near the leading end of the carrier tape CT engages with the feed pin 22P of the introduction sprocket 22A.

[0096] After the feed hole KH near the leading end of the carrier tape CT pushed in by the operator contacts the feed pin 22P of the introduction sprocket 22A and stops just before engaging with the feed pin 22P, when the operation switch (not shown) is operated, the control unit 23 operates the sprocket drive motor 22D to rotate the three sprockets (the introduction sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C). As a result, the carrier tape CT on the conveying path 21L starts to move toward the tape outlet 21B.

[0097] The leading end of the carrier tape CT traveling on the conveying path 21L abuts against the inclined portion 24S of the rear end of the tape cover 24 from behind, and while pushing up the entire tape cover 24, enters between the tape cover 24 and the conveying path 21L ( Fig.10 → Fig.11 As described above, the inclined portion 24S of the tape cover 24 has a shape that gradually moves away from the conveying path 21L toward the rear (upstream side), so the leading end of the carrier tape CT can smoothly enter between the tape cover 24 and the conveying path 21L.

[0098] After the leading end of the carrier tape CT enters between the tape cover 24 and the conveying path 21L, the control unit 23 causes the air blowing unit 25 to blow out the air 25A ( Fig.11 Thus, the extended portion SD of the cover tape TT is guided in such a manner that its front end is blown upward and moves upward through the cover tape passage 24T toward the top of the tape cover 24 (that is, toward the top of the base tape BT). Fig.11 ).

[0099] The extended portion SD of the cover tape TT that has passed through the cover tape passage 24T and moved upwardly toward the tape cover 24 is pulled up by having its front end portion sandwiched (caught) by the first roller 26 and the second roller 27 that rotate in opposite directions ( Fig.12 As described above, the first roller 26 and the second roller 27 operate at the same timing as the three sprockets (the introduction sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C), so the first roller 26 and the second roller 27 pull up the cover tape TT in conjunction with the movement of the carrier tape CT. Therefore, the cover tape TT is subsequently peeled off from the base tape BT in accordance with the movement of the carrier tape CT.

[0100] Thus, in the present embodiment, the air ejection unit 25 functions as a guide mechanism for guiding the extension portion SD of the cover tape TT formed in a manner protruding from the leading end of the base tape BT on the conveying path 21L toward the upper side of the base tape BT at a position upstream of the component removal position 16T. In addition, the first roller 26 and the second roller 27 sandwich (capture) the extension portion SD of the cover tape TT guided toward the upper side of the base tape BT by the guide mechanism (air ejection unit 25) and rotate, and pull up the cover tape TT to form a peeling portion HB ( Figure 4 as well as Figure 6 ).

[0101] The cover tape TT pulled up by the first roller 26 and the second roller 27 and peeled off from the base tape BT is guided by the guide surface 41M of the guide portion 41 and moves backward in an arc shape along the outer peripheral surface of the first roller 26 ( Fig.12 ). Then, the cover tape TT is sandwiched by the first roller 26 and the third roller 28 rotating in opposite directions and conveyed to the rear (upstream side), and is sent to the cover tape discharge path 21J described above ( Fig.13 → Fig.14 ).

[0102] Thus, the tape feeder 16 in the present embodiment has the following structure, comprising: a first roller 26 and a second roller 27, which capture the cover tape TT of the carrier tape CT conveyed by the conveying mechanism 22 and peel it off from the base tape BT; and a third roller 28, which sandwiches the cover tape TT peeled off from the base tape BT between the third roller 28 and the first roller 26 and sends it to the cover tape discharge path 21J. The first roller 26 and the third roller 28 function as "two rollers for cover tape discharge" in the present embodiment.

[0103] As described above, the tape feeder 16 performs a peeling action of peeling the cover tape TT from the base tape BT in conjunction with the conveying action of conveying the carrier tape CT by the conveying mechanism 22. The position where the cover tape TT is peeled from the base tape BT is at a position on the upstream side of the component removal position 16T, so the component BH accommodated in the carrier tape CT (base tape BT) is not covered by the cover tape TT during the period from when the cover tape TT is peeled off to when the component BH reaches the component removal position 16T, but is covered from above by the tape cover 24, so that the component BH is maintained in the concave pocket PK of the base tape BT.

[0104] When the component BH stored in the carrier tape CT reaches the component removal position 16T, it is exposed upward through the component removal opening 24K of the tape cover 24. Thus, the component mounting device 1 can use the mounting head 13 (nozzle 14) to suck and remove the component BH through the component removal opening 24K ( Fig.14 ).

[0105] In this way, the tape feeder 16 in the present embodiment becomes an automatic tape setting type tape feeder as follows: while conveying the carrier tape CT on which the cover tape TT is attached to the base tape BT accommodating the component BH, the cover tape TT is captured by the first roller 26 and the second roller 27 at a position closer to the front (upstream) side than the component removal position 16T and is automatically peeled off from the base tape BT, thereby supplying the component BH to the component removal position 16T.

[0106] When the component mounting device 1 having the above-mentioned tape feeder 16 as the component supply device performs a component mounting operation of mounting the component BH on the substrate KB, first, the substrate KB is supplied from the outside of the component mounting device 1. After the substrate KB is supplied, the substrate conveying unit 12 operates to carry the substrate KB in and position it at a predetermined operation position. After the substrate conveying unit 12 positions the substrate KB at the operation position, each tape feeder 16 starts a component supply operation of continuously supplying the component BH to the component removal opening 24K.

[0107] After each tape feeder 16 starts the component supply operation, the mounting head 13 uses the nozzle 14 to suck and take out the component BH supplied by the tape feeder 16 to the component taking-out position 16T. After taking out the component BH from the tape feeder 16, the mounting head 13 moves above the substrate KB and mounts the component BH on the target component mounting position determined on the substrate KB.

[0108] After the mounting head 13 mounts all the components BH to be mounted on the substrate KB as described above, the substrate transport unit 12 operates to carry the substrate KB out of the component mounting device 1. Thus, the component mounting operation for one substrate KB is completed.

[0109] The tape feeder 16 in this embodiment is used as an automatic tape setting type as described above, but can also be used as a manual tape setting type that performs a feeding operation of the component BH without the capture process of the cover tape TT by the first roller 26 and the second roller 27. In this case, after the operator manually pulls the cover tape TT peeled off from the base tape BT backward from the cover tape pull-out opening 24G, the operator manually clamps it between the two rollers (the first roller 26 and the third roller 28) for the cover tape discharge.

[0110] When the operator sandwiches the cover tape TT pulled out from the cover tape pulling-out opening 24G to the rear between the two rollers (the first roller and the third roller) for the cover tape discharge, the operator first places the roller support body 31 in the open position ( Fig. 9 (a) → Fig. 9 (b) → Fig. 9 (c)) to separate the third roller 28 from the first roller 26 ( Fig.15 After the third roller 28 is separated from the first roller 26, the leading end of the cover tape TT is positioned above the first roller 26 ( Fig.16 (a)). Then, the roller support body 31 is pressed toward the swing shaft 32 by overcoming the biasing force of the biasing spring 35 ( Fig.16 The roller support body 31 is swung around the swing shaft 32 while maintaining the pressed state (arrow P shown in (a)). Fig.16 (a) → Fig.16 (b)).

[0111] After the roller support body 31 is swung so that the left and right protrusions 36 provided on the roller support body 31 are located behind the two engagement grooves 21M formed in the frame 21 ( Fig.16 (b)), the operator releases his finger from the roller support body 31, and the pressure on the roller support body 31 is released. When the operator releases his finger from the roller support body 31, the roller support body 31 moves forward under the action of the force of the biasing spring 35, and the left and right protrusions 36 engage with the left and right engaging grooves 21M ( Fig.16 (b) → Fig.16 (c)). As a result, the roller support body 31 is located in the closed position and is locked in the frame 21 ( Fig.16 (c)).

[0112] When the roller support body 31 is located at the closed position as described above, the cover tape TT whose leading end is located above the first roller 26 is sandwiched between the two rollers (the first roller 26 and the third roller 28) for the cover tape discharge. Thus, in the present embodiment, when the roller support body 31 is located at the open position (the second position), the third roller 28 is separated from the first roller 26, and when the roller support body 31 is located at the closed position (the first position), the third roller 28 sandwiches the cover tape TT between the first roller 26. After the cover tape TT is sandwiched by the two rollers (the first roller 26 and the third roller 28) for the cover tape discharge, the preparation work for using the tape feeder 16 as a manual tape setting type is completed.

[0113] After the preparation work for using the tape feeder 16 as a manual tape setting type is completed, when the conveying mechanism 22 is operated by the control unit 23, the carrier tape CT is conveyed by the three sprockets (the introduction sprocket 22A, the positioning sprocket 22B, and the discharge sprocket 22C), and the two rollers for cover tape discharge (the first roller 26 and the third roller 28) also rotate in conjunction. As a result, the cover tape TT is peeled off together with the conveyance of the carrier tape CT, and the peeled cover tape TT is sent out to the cover tape discharge path 21J by the two rollers for cover tape discharge (the first roller 26 and the third roller 28). Fig.17 ).

[0114] Thus, in the present embodiment, when the tape feeder 16 is used as the automatic tape setting type, the third roller 28 sandwiches the cover tape TT peeled off from the base tape BT between the third roller 28 and the first roller 26 and delivers it to the cover tape discharge path 21J, and when the tape feeder 16 is used as the manual tape setting type, the cover tape TT peeled off from the base tape BT by manual operation is sandwiched between the third roller 28 and the first roller 26 and delivers it to the cover tape discharge path 21J. That is, the third roller 28 sandwiches the cover tape TT peeled off from the base tape BT by the first roller 26 and the second roller 27 or the cover tape TT peeled off from the base tape BT by manual operation between the third roller 28 and the first roller 26 and delivers it to the cover tape discharge path 21J.

[0115] In the tape feeder 16 of the present embodiment, the first roller 26 and the second roller 27 are mounted on the frame 21, and on the other hand, the third roller 28 is mounted on the roller support body 31. Therefore, when used as a manual tape setting type, the operator places the roller support body 31 in the open position, and then places the leading end of the cover tape TT peeled off from the base tape BT by manual operation between the first roller 26 and the third roller 28, and then swings the roller support body 31 to the closed position, thereby completing the preparation work easily and in a short time.

[0116] As described above, in the tape feeder 16 of the automatic tape setting type in the present embodiment, the first roller 26 of the two rollers (the first roller 26 and the third roller 28) for discharging the cover tape, which is manually separated from the base tape BT and is fed to the cover tape discharge path 21J, is mounted on the frame 21, and the third roller 28 is supported (mounted) on the roller support body 31, and the roller support body 31 is freely movable between the first position (closed position) in which the third roller 28 and the first roller 26 sandwich the cover tape TT and the second position (open position) in which the third roller 28 is separated from the first roller 26, so that the operation of sandwiching the cover tape TT between the two rollers for discharging the cover tape can be performed only by the action of making the roller support body 31 located at the second position be located at the first position. Therefore, according to the present embodiment, when the tape feeder 16 of the automatic tape setting type is used as the manual tape setting type, the required preparation operation can be performed quickly and easily.

[0117] So far, the embodiments of the present invention have been described, but the present invention is not limited to the above contents, and various modifications are possible. For example, in the above-mentioned embodiment, the urging mechanism that urges the third roller 28 in the direction of pressing the first roller 26 when the roller support body 31 is located in the first position (closed position) is composed of a spring member (urging spring 35) as an elastic member, but the urging mechanism may also be composed of other elastic members (rubber members, etc.) other than the spring member.

[0118] In addition, the roller support body 31 may be a structure that supports the third roller 28 and is movable between the first position and the second position. Therefore, instead of the structure in which one end (rear end) of the roller support body 31 is attached to the frame 21 via the swing shaft 32 extending in the width direction (X direction) of the frame 21 as in the above-mentioned embodiment, a structure in which one end side of the roller support body 31 in the left-right direction is attached to the frame 21 via a swing shaft extending in the length direction (Y direction) of the frame 21 may be used. Alternatively, a structure that is movable between the first position and the second position by moving parallel to the frame 21 in the up-down direction may be used.
