Description

  The present invention relates to a component supply apparatus and a component supply method for supplying components stored in a component storage portion of a carrier tape.

  Conventionally, a carrier tape has been used to supply components to a nozzle of a transfer head of a component mounting apparatus that mounts components on a substrate. The carrier tape includes a base tape having a main surface in which a plurality of concave or embossed component storage portions for storing components are formed side by side in the tape longitudinal direction, and a plurality of component storage portions in a state in which the components are stored. And a top tape attached to the main surface of the base tape so as to cover. The top tape is peeled from the main surface of the base tape so that the nozzle of the transfer head of the component mounting apparatus can adsorb the components in the component accommodating portion of the carrier tape.

  For example, Patent Document 1 discloses that a top tape is peeled from a base tape by using a top tape peeling member having a blade edge. Specifically, the top tape peeling member is arranged on the tape path of the carrier tape sent in the tape longitudinal direction (tape feeding direction). The top tape is peeled from the base tape by the blade edge of the top tape peeling member entering the tape feeding direction between the top tape and the base tape from the front end side of the carrier tape moving in the tape feeding direction.

  For example, the component supply apparatus described in Patent Document 1 is configured to sequentially feed a plurality of carrier tapes in the longitudinal direction of the tape. Specifically, the carrier tape is guided by a guide member facing the back surface (the surface of the base tape opposite to the main surface), and a component supply position that is a position for supplying the component to the component mounting apparatus. Toward the tape in the longitudinal direction (tape feed direction). In the state where it overlaps the main surface of the previous carrier tape that supplies components to the component mounting device at the component supply position, the component will be supplied at the component supply position after the previous carrier tape. The subsequent carrier tape (following carrier tape) waits. The stopper member is in contact with the front end of the subsequent carrier tape in the tape feeding direction so that the subsequent carrier tape arranged with the back surface overlapping the main surface of the preceding carrier tape does not move together with the preceding carrier tape. Note that the preceding carrier tape moves under the stopper member toward the component supply position.

  When the trailing edge of the leading carrier tape in the tape feeding direction passes the leading edge of the trailing carrier tape in the tape feeding direction (when the overlap between the leading carrier tape and the trailing carrier tape is eliminated), the trailing carrier tape guides the back surface of the carrier tape. Arranged on the guide member. Specifically, the waiting subsequent carrier tape is biased in the tape thickness direction by the tape biasing member toward the preceding carrier tape (that is, the guide member that guides the back surface of the preceding carrier tape in the tape thickness direction) ( In other words, the preceding carrier tape and the succeeding carrier tape are sandwiched between the tape biasing member and the guide member in the tape thickness direction). When the rear end of the preceding carrier tape in the tape feeding direction passes the front end of the subsequent carrier tape in the tape feeding direction, the subsequent carrier tape is urged by the tape urging member in the tape thickness direction and disposed on the guide member. As a result, the subsequent carrier tape is fed toward the component supply position while being guided by the guide member following the preceding carrier tape.

JP 2011-2111169 A

  By the way, in the case of the component supply apparatus described in Patent Document 1, the subsequent carrier tape waiting in a state of being sandwiched with the preceding carrier tape between the tape biasing member and the guide member is the tape biasing member and the guide. There is a possibility of unintentionally coming out from between the members unintentionally in the direction opposite to the tape feeding direction. That is, there is a possibility that the succeeding carrier tape that has been waiting on the tape path toward the component supply position may be removed from the tape path. As a result, the subsequent carrier tape cannot be sent following the preceding carrier tape.

  Moreover, the component supply apparatus described in Patent Document 1 causes the subsequent carrier tape to be interrupted between the main surface of the preceding carrier tape that is biased in the tape thickness direction by the tape biasing member and the tape biasing member. Therefore, the thin carrier tape may bend without being able to enter between the main surface of the preceding carrier tape and the tape biasing member. As a result, there is a possibility that the thin subsequent carrier tape cannot easily stand by between the main surface of the preceding carrier tape and the tape biasing member.

  Therefore, in the present invention, following the preceding carrier tape that supplies components to the component mounting apparatus in advance, the subsequent carrier tape that is scheduled to supply the components next is supplied to the component mounting apparatus. Even if the carrier tape is thin so that it can be sent to the component supply position, which is the supply position, it is an object to reliably wait for the subsequent carrier tape on the tape path toward the component supply position.

When the roller main body 34a of the pin roller 34 is rotated so that the carrier tape 200 is fed in the tape feeding direction A around the rotation center line C2 with the pin 34c engaged with the feed hole 208, the carrier tape 200 is moved to the first direction. It moves along the secondary tape path P1.

  It should be noted that the first and second tape guide portions 32L, 32b, so that the feed hole 208 of the carrier tape 200 can be easily engaged with the pin 34c of the pin roller 34 located on the upstream side in the tape feed direction A of the tape insertion port 12a. 32R guides the carrier tape 200 to guide the pin 34 of the pin roller 34 engaged with the feed hole 208 of the carrier tape 200 on the first sub tape path P1 from the upstream side in the tape feed direction A. Is preferred.

  That is, preferably, the guide blocks 36L, 36R in the first and second tape guide portions 32L, 32R and the inner side surface 38a of the fixed bracket 38 and the inner side surface 40d of the side wall portion 40b in the movable bracket 40 are in relation to the pin roller 34. Thus, it is configured to extend in the tape feeding direction A from the upstream side in the tape feeding direction A.

  In particular, the first and second tape guide portions 32L and 32R feed the carrier tape 200 to the inner side surface 38a of the fixed bracket 38 that functions as a guide in the tape width direction and the inner side surface 40d of the side wall portion 40b of the movable bracket 40. It is preferable to provide at least the upstream side in the tape feeding direction A with respect to the pin 34c of the pin roller 34 engaged with the hole 208. As a result, the carrier tape 200 passes under the pin roller 34 with the position (X-axis direction position) of the pin 34c of the pin roller 34 and the feed hole 208 of the carrier tape 200 aligned (guided). Can be made. As a result, the feed hole 208 of the carrier tape 200 can be easily engaged with the pin 34c of the pin roller 34.

  Further, the pin roller 34 is configured to restrict the movement of the carrier tape 200 in which the pin 34 c is engaged with the feed hole 208 in the direction opposite to the tape feed direction A. Specifically, the rotation direction (counterclockwise direction in FIG. 3) of the roller main body portion 34a of the pin roller 34 that is rotated by movement of the carrier tape 200 in which the pin 34c is engaged with the feed hole 208 in the tape feed direction A. The roller body 34 of the pin roller 34 is configured to be non-rotatable in the direction opposite to the above.

  In the case of the present embodiment, the roller body 34a of the pin roller 34 is supported by the support shaft 44 via a clutch mechanism (one-way clutch) 42 accommodated therein. The support shaft 44 extends in the tape width direction (X-axis direction) of the carrier tape 200 on the first sub tape path P1. Further, both ends of the shaft 44 are supported by side wall portions 40a and 40b of the movable bracket 40 as shown in FIG.

  The clutch mechanism 42 is configured to limit the rotation direction of the roller body 34 a of the pin roller 34 relative to the support shaft 44 to one direction. That is, the clutch mechanism 42 is configured to allow only the rotation of the roller main body 34a in the direction in which the carrier tape 200 with the pin 34c engaged with the feed hole 208 can move in the tape feed direction A.

  By such a pin roller 34, the carrier tape 200 on the first sub tape path P1 is restricted from moving in the direction opposite to the tape feeding direction A. That is, the carrier tape 200 on the first sub tape path P <b> 1 moves in the direction opposite to the tape feeding direction A, thereby preventing the carrier tape 200 from being unintentionally removed from the main body 12 of the component supply device 10. As a result, the carrier tape 200 can be reliably kept on standby on the first sub tape path P1. If the carrier tape 200 is intended to be removed, the movable bracket 40 provided with the pin roller 34 is moved relative to the tape thickness direction so as to be spaced apart above the carrier tape 200. The engagement between the pin 34c and the feed hole 208 of the carrier tape 200 is released, so that the carrier tape 200 can be easily pulled out intentionally.

  As shown in FIG. 4, the roller body 34 of the pin roller 34 has a main surface 204a of the base tape 204 over the entire tape width direction (X-axis direction) of the carrier tape 200 on the first sub tape path. Although the outer peripheral part 34b which opposes is provided, embodiment of this invention is not restricted to this. For example, the outer peripheral portion 34b of the roller body 34 may be configured to face only the feed hole 208 in the carrier tape 200 on the first sub tape path P1. For example, like the sprocket, the roller body 34a may have a minimum tape width direction (X-axis direction) size capable of forming a plurality of pins 34c.

  A method for sequentially feeding a plurality of carrier tapes 200 in the tape feeding direction A toward the component supply position Q1 using the first and second sub tape paths P1 and P2 as described above will be described.

  As a premise, the component supply device 10 of the present embodiment is configured to use the first sub tape path P1 when the carrier tape 200 is loaded into the main body 12 of the component supply device 10. For example, as shown in FIG. 3, when the carrier tape 200 (that is, the preceding carrier tape 200A) is inserted into the main body 12 of the component supply apparatus 10 in a state where the carrier tape 200 is not inserted, the first sub tape is supplied. Tape path P1 is used. Further, for example, when the carrier tape 200 (following carrier tape 200B) following the carrier tape 200 (preceding carrier tape 200A) already loaded into the main body 12 of the component supply apparatus 10 is loaded into the main body 12 of the component supply apparatus 10. In addition, the first sub tape path P1 is used.

  As shown in FIG. 3, the carrier tape 200 (preceding carrier tape 200 </ b> A) is placed on the first sub tape path P <b> 1, for example, by the operator's manual work. Specifically, first, the front end portion of the carrier tape 200 (preceding carrier tape 200A) in the tape feeding direction A is on the guide blocks 36L and 36R of the first and second tape guide portions 32L and 32R of the tape holding unit 30. Placed in.

  The carrier tape 200 (preceding carrier tape 200A) disposed on the guide blocks 36L and 36R of the first and second tape guide portions 32L and 32R of the tape holding unit 30 is moved in the tape feeding direction A by the operator's manual work. Sent. The carrier tape 200 (preceding carrier tape 200A) fed in the tape feeding direction A by the operator enters between the tape guides 36L and 36R and the pin roller 34 (gap l), and the feed hole 208 is a pin of the pin roller 34. 34c is engaged. When the feed hole 208 is engaged with the pin 34c of the pin roller 34, the carrier tape 200 (preceding carrier tape 200A) is not unintentionally removed from the component supply device 10.

  When the operator rotates the pin roller 34 with the pin 34c engaged with the feed hole 208 so as to feed the carrier tape 200 in the tape feeding direction A, the carrier tape 200 (the preceding carrier tape 200A) is moved to the first sub tape path. The tape is fed in the tape feeding direction A along P1 toward the insertion port 12a of the main body 12 of the component supply device 10.

  Even if the carrier tape 200 (preceding carrier tape 200A) that has passed through the insertion port 12a is a thin carrier tape due to the rotation of the pin roller 34 by the operator's manual work, the carrier tape 200 is reliably fed in the tape feeding direction A. Along the tape path P0, it heads to the sprocket 14 located on the most upstream side in the tape feeding direction A.

  As shown in FIG. 6, when the feed hole 208 of the carrier tape 200 (the preceding carrier tape 200A) is engaged with the teeth 14a of the sprocket 14, the tape feed by the pin roller 34 is completed. For example, when the operator presses a button such as a “tape set completion button”, or when the carrier tape 200 reaches the position on the main tape path P0 where the feed hole 208 engages with the teeth 14a of the sprocket 14, for example. (Not shown) detects, for example, by detecting the start of rotation of the sprocket 14 by the carrier tape 200 being moved by the rotation of the pin roller 34, the carrier tape 200 (preceding carrier tape 200A) is applied to the teeth 14a. The sprocket 14 in a state of being engaged with the feed hole 208 starts to rotate.

  As the sprocket 14 rotates, as shown in FIG. 6, the carrier tape 200 (preceding carrier tape 200A) is fed along the main tape path P0 toward the sprocket 16 located further downstream in the tape feeding direction A. When the feed hole 208 of the carrier tape 200 (preceding carrier tape 200A) is engaged with the teeth 16a of the sprocket 16, the sprocket 14 stops rotating and can freely rotate (a motor (not shown) that drives the sprocket 14). To the state in which the excitation is canceled).

  As shown in FIG. 1, the carrier tape 200 (preceding carrier tape 200A) fed in the tape feeding direction A by the sprocket 16 is peeled off by the cutting edge 20a of the top tape peeling portion 20 at the top tape peeling position Q1. Subsequently, the feed hole 208 is engaged with the teeth 18a of the sprocket 18 located between the top tape peeling portion 20 and the component supply position Q1. The carrier tape 200 (preceding carrier tape 200A) is fed in the tape feeding direction A toward the component supply position Q1 by the two sprockets 16 and 18.

  As shown in FIG. 1, the carrier tape 200 (preceding carrier tape 200A) fed in the tape feeding direction A by the two sprockets 16 and 18 is moved toward the nozzle 102 of the transfer head 100 of the component mounting apparatus at the component supply position Q1. Then, the parts exposed to the outside by peeling off the top tape 206 are supplied.

  Subsequent carrier that is scheduled to supply the next component following the preceding carrier tape 200A at an arbitrary timing while the preceding carrier tape 200 is supplying the component to the nozzle 102 of the transfer head 100 of the component mounting apparatus. The tape 200 </ b> B is disposed on the main body 12. Specifically, as shown in FIG. 6, the preceding carrier tape 200A moving on the first sub tape path P1 is moved to the second sub tape path P2, and thereby, the first sub tape path P1 is vacated. The subsequent carrier tape 200B is arranged. This will be described.

  The movement of the preceding carrier tape 200A from the first sub tape path P1 to the second sub tape path P2 is executed by turning the movable bracket 40 of the tape holding unit 30 around the rotation center line C1.

  As shown in FIG. 6, the operator moves the movable bracket 40 of the tape holding unit 30 around the rotation center line C1 from the state where the preceding carrier tape 200A moves in the tape feeding direction A on the first sub tape path P1. Turn as.

  By turning the movable bracket 40 of the tape holding unit 30 disposed on the main surface 204a side of the preceding carrier tape 200A, as shown in FIG. 7, the pin roller 34 supported by the movable bracket 40 and the second tape guide portion 32R. Moves up, that is, moves away from the main surface 204a side of the preceding carrier tape 200A on the first sub tape path P1.

  When the pin roller 34 is lifted by turning the movable bracket 40 of the tape holding unit 30, the first tape guide portion 32 </ b> L (guide block 36 </ b> L) of the fixed bracket 38 is relative to the pin roller 34 in the tape thickness direction (Z-axis direction). Move in the direction of separating. Accordingly, the pin 34c of the pin roller 34 engaged with the feed hole 208 of the preceding carrier tape 200A (see FIG. 4) feeds the preceding carrier tape 200A on the first sub tape path P1 as shown in FIG. Retreat relatively from the hole 208. As a result, the preceding carry tape 200A is movable in the tape width direction (X-axis direction) from between the first tape guide portion 32L (guide block 36L) on the feed hole 208 side and the roller main body portion 34a of the pin roller 34. Put into a state.

  Further, when the second tape guide portion 32R (guide block 36R) rises in the direction away from the main surface 204a side of the preceding carrier tape 200A by the turning of the movable bracket 40 of the tape holding unit 30, it is placed on the guide block 36R. The other side of the preceding carrier tape 200A in the tape width direction (the side opposite to the feed hole 208 side) is lifted. Thereby, the preceding carrier tape 200A is partially twisted (in FIG. 7, the dotted line indicates the preceding carrier tape 200A before twisting). Specifically, the preceding carrier tape 200A turns around the vicinity of the second tape guide portion 32R, and a portion near the second tape guide portion 32R (guide block 36R) is twisted as compared with other portions.

  As shown in FIG. 7, the second tape guide portion 32R (guide block 36R) of the movable bracket 40 is further moved from the state where the preceding carrier tape 200A is twisted so that the other side in the tape width direction opposite to the feed hole 208 side is lifted. 8), as shown in FIG. 8, the other side of the preceding carrier tape 200A in the tape width direction slides down from above the guide block 36R, and moves below the guide block 36R while eliminating twisting.

  As shown in FIG. 8, the second tape guide portion 32R is relatively raised above the preceding carrier tape 200A, and the other side in the tape width direction of the preceding carrier tape 200A opposite to the feed hole 208 side is the first. When the support of the second tape guide portion 32R (guide block 36R) is lost, the preceding carrier tape 200A falls downward. In other words, the preceding carrier tape 200A on the first sub tape path P1 passes between the first and second tape guide portions 32L and 32R and is present below the first sub tape path P1. It moves toward the secondary tape path P2. Accordingly, as shown in FIGS. 9 and 10, the preceding carrier tape 200A is moved from the first sub tape path P1 to the second sub tape path P2.

  Here, guide members for guiding (supporting) the carrier tape 200 on the first sub tape path P1 from below are first and second tape guide portions 32L and 32R (guide blocks) of the tape holding unit 30. 36L, 36R) will be described.

  For example, consider a case where one guide member guides (supports) the carrier tape 200 on the first sub tape path P1 from below. In this case, when the carrier tape 200 is moved from the first sub tape path P1 to the second sub tape path P2 positioned below the first sub tape path P1, it is positioned between the first and second sub tape paths P1, P2. Therefore, it is necessary to move the carrier tape 200 so as to bypass one guide member. That is, it is necessary to greatly change the tape width direction position (X-axis direction position) of the carrier tape 200. Therefore, it is necessary to secure a space for the carrier tape 200 to bypass one guide member.

  If a space for the carrier tape 200 to bypass such one guide member is provided, the size of the component supply device 10 in the tape width direction (X-axis direction) must be increased. As a result, the number of component supply devices 10 mounted in a state of being closely arranged in the tape width direction (X-axis direction) with respect to one component mounting device decreases.

  On the other hand, as shown in FIG. 4, the first and second tape guide portions 32L and 32R (guide blocks 36L, 36R), when guiding (supporting) from below both ends of the tape width direction, when moving the carrier tape 200 from the first sub tape path P1 to the second sub tape path P2 positioned below the first sub tape path P1, The carrier tape 200 can easily pass so as to pass between the first and second tape guide portions 32L and 32R. That is, the carrier tape 200 can move from the first sub tape path P1 to the second sub tape path P2 below the first sub tape path P1 without largely changing the tape width direction position (X-axis direction position). Therefore, the size of the component supply device 10 in the tape width direction (X-axis direction) can be reduced.

  When the pin roller 34 is raised by the turning of the movable bracket 40 of the tape holding unit 30, the pin 34c is taped from the feed hole 208 of the carrier tape 200 (preceding carrier tape 200A) on the first sub tape path P1. It is preferable to be able to reliably retract (disengagement) in the thickness direction (Z-axis direction).

  In the case of the present embodiment, as shown in FIG. 7, the pin roller 34 extends in the tape thickness direction (Z-axis direction) from the feed hole 208 of the carrier tape 200 (preceding carrier tape 200A) on the first sub tape path P1. When the pin 34c is lifted and retracted, the carrier tape 200A on the main surface 204a side of the carrier tape 200A on the retracting direction (that is, the tape thickness direction) side of the pin 34c and the tape width direction (X-axis direction) ) Has a tape pressing part 46 for pressing one side.

  As shown in FIG. 4, the tape pressing portion 46 extends from the inner side surface 38a of the fixing bracket 38 of the tape holding unit 30 to above the feed hole 208 of the carrier tape 200 on the first sub tape path P1. This is a member (or a part of the fixed bracket 38) to be operated. In the case of the present embodiment, the tape pressing portion 46 is also located on the downstream side in the tape feeding direction A with respect to the first tape pressing portion 32L as shown in FIG.

  When the pin roller 34 and the second tape guide portion 32R are lifted by the turning of the movable bracket 40 of the tape holding unit 30, the tape pressing portion 46 presses the carrier tape 200 (preceding carrier tape 200A) from above, so that the pin roller 34 pins 34c can be reliably retracted from the feed hole 208 of the carrier tape 200 (preceding carrier tape 200A). That is, together with the pin roller 34 and the second tape guide portion 32R, the carrier tape 200 (preceding carrier tape 200A) is suppressed from moving upward from the first sub tape path P1.

  Further, as shown in FIG. 8, after the second tape guide portion 32R moves from the lower side to the upper side of the carrier tape 200 (preceding carrier tape 200A) by the turning of the movable bracket 40 of the tape holding unit 30, the movable bracket 40 is moved. , The carrier tape 200 (the preceding carrier tape 200A) may be pushed down toward the second sub tape path P2 below by the second tape guide portion 32R. For example, when the second tape guide portion 32R moves from the lower side to the upper side of the carrier tape 200 (preceding carrier tape 200A), the carrier tape 200 (preceding carrier tape 200A) is unlikely to naturally fall. This is effective (for example, in the case of a carrier tape having a large tape thickness).

  As shown in FIGS. 9 and 10, when the preceding carrier tape 200A moves from the first sub tape path P1 to the second sub tape path P2, the succeeding carrier tape 200B is moved to the vacant first sub tape path P1. It becomes possible to arrange.

  Similarly to the preceding carrier tape 200A, the subsequent carrier tape 200B is manually guided by the operator, and the front end portion in the tape feeding direction is the guide block 36L of the first and second tape guide portions 32L and 32R of the tape holding unit 30. , 36R. The succeeding carrier tape 200B placed on the guide blocks 36L and 36R passes below the pin roller 34 by the tape feeding in the tape feeding direction A by the operator's manual work, and the pin 34c of the pin roller 34 is inserted into the feeding hole 208. Engage. Thereby, the succeeding carrier tape 200B can reliably stand by on the first sub tape path P1 without unintentionally coming off.

  In addition, the component supply apparatus 10 of the present embodiment has a first sub tape following the preceding carrier tape 200A that is fed in the tape feeding direction A along the second sub tape path P2 and the main tape path P0. It has an automatic tape feeding mechanism 50 that starts automatically feeding the succeeding carrier tape 200B waiting on the path P1.

  First, in order to automatically start the feeding of the subsequent carrier tape 200B by the automatic tape feeding mechanism 50, as shown in FIG. 11, the front end 210B of the subsequent carrier tape 200B in the tape feeding direction A is the first sub tape path P1. The subsequent carrier tape 200B waits in a state where it enters the main tape path P0. Specifically, when the operator rotates the pin roller 34, the front end 210B of the subsequent carrier tape 200B in the tape feeding direction A is inserted from the first sub tape path P1 into the main tape path P0.

  Further, the leading end 210B in the tape feeding direction A of the subsequent carrier tape 200B that has entered the main tape path P0 is fed in the tape feeding direction A along the second sub tape path P2 and the first sub tape path P1. The succeeding carrier tape 200B stands by in a state of being overlapped with the carrier tape 200A.

  For this purpose, the upper guide surface 12c of the main body part 12 disposed above and facing the carrier tape 200 on the main tape path P0 and the lower guide surface 12d disposed below and opposed to the carrier tape 200 are opposed. Has a gap through which two carrier tapes 200 overlapping in the tape thickness direction can pass in the vicinity of the tape insertion opening 12a.

  As shown in FIG. 11, the automatic tape feeding mechanism 50 urges the sprocket 14 arranged on the most upstream side in the tape feeding direction A and the carrier tape 200 on the main tape path P0 toward the sprocket 14. A block 52 and a stopper 54 for waiting the subsequent carrier tape 200B are provided.

  The urging block 52 of the automatic tape feeding mechanism 50 is disposed so as to face the sprocket 14 across the main tape path P0, and is on the main tape path P0 (that is, the upper guide surface 12c and the lower guide surface 12d of the main body 12). The carrier tape 200 (which is disposed between the two) is urged toward the sprocket 14. Specifically, as shown in FIG. 3, the urging block 52 can move forward and backward from the lower guide surface 12d toward the sprocket 14, and is directed toward the sprocket 14 by an urging member (for example, a spring) (not shown). It is energized. The two-dot chain line in FIG. 3 shows the urging block 52 in a state of being retracted from the lower guide surface 12d.

  On the other hand, the teeth 14a of the sprocket 14 facing the biasing block 52 protrude from the upper guide surface 12c toward the biasing block 52 as shown in FIG.

  The carrier tape 200 disposed between the upper guide surface 12c and the lower guide surface 12d is urged by the urging block 52 and comes into contact with the upper guide surface 12c, and its feed hole 208 is in contact with the teeth 14a of the sprocket 14. Engage.

  When the preceding carrier tape 200A and the succeeding carrier tape 200B are overlapped between the biasing block 52 and the sprocket 14, the teeth 14a of the sprocket 14 are engaged with the feed hole 208 of the upper succeeding carrier tape 200B. Match.

  The stopper 54 of the automatic tape feeding mechanism 50 includes a tape locking portion 54a that can move forward and backward from the upper guide surface 12c of the main body portion 12 toward the lower guide surface 12d.

  As shown in FIG. 11, the preceding carrier tape 200A fed in the tape feeding direction A by the sprocket 16 (or sprockets 16, 18) (see FIG. 1) along the second sub tape path P2 and the main tape path P0. The tape locking portion 54a of the stopper 54 comes into contact with the front end 210B in the tape feeding direction A of the succeeding carrier tape 200B overlapping therewith. As a result, the movement of the preceding carrier tape 200A in the tape feeding direction A and the movement of the subsequent carrier tape 200B toward the component supply position Q1 are suppressed.

  When the carrier tape 200 does not exist between the urging block 52 and the sprocket 14 or when only one carrier tape 200 exists, the tape locking portion 54a of the stopper 54 is as shown in FIGS. Retreating from the upper guide surface 12c.

  For example, advancement / retraction of the tape locking portion 54 a of the stopper 54 is executed in conjunction with advancement / retraction of the urging block 52. For example, the urging block 52 is lowered to the position where the two carrier tapes 200 exist between the urging block 54 and the sprocket 14, so that the tape locking portion 54 a of the stopper 54 moves downward from the upper guide surface 12 c. Protrusively.

  Since the component supply apparatus 10 has such an automatic tape feeding mechanism 50, the subsequent carrier tape 200B waiting on the first sub tape path P1 is transferred to the second sub tape path P2 and the main tape path P0. Then, it can be automatically fed following the preceding carrier tape 200A being fed in the tape feeding direction A.

  As described above, according to the present embodiment, the component is scheduled to be supplied next to the preceding carrier tape 200A that supplies the component to the nozzle 102 of the transfer head 100 of the component mounting apparatus. Even if the carrier tape 200 is thin so that the subsequent carrier tape 200B can be sent to the component supply position toward Q1, the subsequent carrier is placed on the first sub tape path P1 toward the component supply position Q1. The tape 200B can be reliably kept on standby.

  Although the present invention has been described with reference to the above-described embodiment, the present invention is not limited to the above-described embodiment.

  For example, in the case of the component supply device 10 of the above-described embodiment, as shown in FIG. 5, the first and second tape guide portions 32L and 32R of the tape holding unit 30 are arranged in the tape width direction (X-axis direction). Although facing each other, the embodiment of the present invention is not limited to this.

  For example, in the case of the tape holding unit 130 of the component supply apparatus according to another embodiment, as shown in FIG. 12, the second tape guide unit 132R (the guide block 36R supported thereby) upstream in the tape feeding direction A. The end of the first tape guide portion 132L (the guide block 36L supported by the first tape guide portion 132L) is arranged so as to be shifted to the downstream side in the tape feed direction A as compared with the upstream end in the tape feed direction A. As a result, the carrier tape 200 on the first sub tape path P1 can easily pass between the first and second tape guide portions 132L and 132R in the tape thickness direction (vertical direction), and the first sub tape. It becomes easy to fall (easy to move) to the second sub tape path P2 located below the path P1 (compared to the case where the first and second tape guide portions face each other in the tape width direction).

  Further, the carrier tape 200 on the first sub tape path P1 can easily pass between the first and second tape guide portions 32L and 32R of the tape holding unit 30 toward the second sub tape path P2. As described above, at least one of the first and second tape guide portions 32L and 32R may be manufactured using a material that can be elastically deformed in the tape width direction (X-axis direction). For example, in the case of the above-described embodiment, at least one of the fixed bracket 38 and the movable bracket 40 of the tape holding unit 30 may be made of a resin material.

  Further, the succeeding carrier tape 200B waiting on the first sub tape path P1 is followed by the preceding carrier tape 200A being fed in the tape feeding direction A along the second sub tape path P2 and the main tape path P0. The automatic tape feeding mechanism that automatically feeds is not limited to the automatic tape feeding mechanism of the above-described embodiment.

  For example, another form of the automatic tape feeding mechanism detects the trailing edge of the tape feeding direction A of the preceding carrier tape 200A fed in the tape feeding direction along the second sub tape path P2 and the main tape path P0. And a sensor (not shown) provided in the tape inlet 12a of the main body 12 of the component supply device 10 and a motor (not shown) for rotating the pin roller 34 of the tape holding unit 30.

  When the sensor provided in the tape insertion opening 12a detects the rear end of the preceding carrier tape 200A, the motor rotates the pin roller 34. As a result, the subsequent carrier tape 200B waiting on the first sub tape path P1 is sent toward the component supply position Q1 following the preceding carrier tape 200A.

  Further, in the case of the component supply apparatus 10 of the above-described embodiment, the movement of the preceding carrier tape 200A from the first sub tape path P1 to the second sub tape path P2 below the first sub tape path P1 is movable of the tape holding unit 30. This is performed by turning the bracket 40 manually. Alternatively, a drive source such as a motor may turn the movable bracket 40.
