Description

The present invention relates to a component supply device that supplies components accommodated in a component storage section of a carrier tape.

2. Description of the Related Art Conventionally, carrier tapes have been used to supply components to a nozzle of a transfer head of a component mounting apparatus that mounts components on a board. The carrier tape includes a base tape having a main surface in which a plurality of concave or embossed component housing portions for storing components are formed side by side in the longitudinal direction of the tape, and a plurality of component housing portions in which components are stored. A top tape is attached to the main surface of the base tape so as to cover the base tape. The top tape is peeled off from the main surface of the base tape so that the nozzle of the transfer head of the component mounting apparatus can pick up the components in the component housing section 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 provided with a cutting edge. Specifically, a top tape peeling member is arranged on the tape path of the carrier tape that is fed in the tape longitudinal direction (tape feeding direction). The cutting edge of the top tape peeling member enters between the top tape and the base tape in the tape feeding direction from the front end side of the carrier tape that is moving in the tape feeding direction, thereby peeling the top tape from the base tape.

Further, for example, the component supply device described in Patent Document 1 is configured to sequentially feed a plurality of carrier tapes in the tape longitudinal direction. Specifically, the carrier tape is guided by a guide member facing its back surface (the surface of the base tape opposite to the main surface), and is positioned at a component supply position, which is a position where components are supplied to a component mounting device. The tape is fed in the longitudinal direction (tape feeding direction) towards the tape. At the component supply position, the carrier tape that is to be supplied to the component mounting device next to the previous carrier tape (preceding carrier tape) is overlapped with the main surface of the carrier tape that is supplying components to the component mounting device. The next carrier tape (subsequent carrier tape) is on standby. A stopper member is in contact with the front end of the trailing carrier tape in the tape feeding direction so that the trailing carrier tape, which is disposed with its back surface overlapping the main surface of the leading carrier tape, does not move together with the leading carrier tape. Note that the preceding carrier tape passes below the stopper member and is moving 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 resolved), the trailing carrier tape guides the back side of the carrier tape. The guide member is placed on the guide member. Specifically, the subsequent carrier tape that is on standby is urged in the tape thickness direction by a tape biasing member toward the preceding carrier tape (i.e., 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 following carrier tape are held 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 succeeding carrier tape in the tape feeding direction, the succeeding carrier tape is urged in the tape thickness direction by the tape biasing member and placed on the guide member. As a result, the subsequent carrier tape is guided by the guide member and sent toward the component supply position following the preceding carrier tape.

(guide blocks 36L, 36R), the carrier tape 200 can move in the tape feeding direction A along the first sub-tape path P1.

Although the reason will be described later, the movable bracket 40 provided with the pin roller 34 rotates around the rotation center line C1 extending in the tape width direction (X-axis direction) of the carrier tape 200 on the first sub-tape path P1. It is rotatably supported on the upstream side in the tape feeding direction A of the tape input port 12a of the main body 12 of the component supply device 10. Specifically, as shown in FIG. 3, the movable bracket 40 includes an arm portion 40e extending from the side wall portion 40a, and is rotatable (the third 1) and is movable upward and away from the carrier tape 200 on the sub-tape path P1.

As shown in FIGS. 3 and 4, the pin roller 34 is provided on a roller main body 34a and an outer circumference 34b of the roller main body 34a, and is engaged with the feed hole 208 in the carrier tape 200 on the first sub-tape path P1. It is provided with a plurality of pins (teeth) 34c that fit together.

In the case of the present embodiment, the roller main body 34a of the pin roller 34, which is movable upward in the tape thickness direction relative to the carrier tape 200 on the first sub-tape path P1, has a cylindrical shape, and The carrier tape 200 on the first sub-tape path P1 rotates about a rotation center line C2 extending in the tape width direction (X-axis direction). The roller body portion 34a of the pin roller 34 also includes an outer peripheral portion 34b facing the main surface 204a of the base tape 204 in the carrier tape 200 on the first tape path P1. The pin roller 34 is attached to the tape holding unit 30 so that a gap l through which the carrier tape 200 can pass is formed in advance between the outer peripheral part 34b and the guide blocks 36L and 36R of the first and second tape guide parts 32L and 32R. It is located in For example, the dimension in the tape thickness direction (Z-axis direction) (for example, 0.15 to 0.0 .5 mm) is formed. That is, the gap between the roller main body 34a of the pin roller 34 and the guide blocks 36L, 36R should have a dimension in the tape thickness direction (at least 0.15 mm or more) that allows the thin carrier tape 200 to easily pass through and prevents tape clogging. with a relative spacing l). The gap l should be formed at least between the guide block 36L on one side in the tape width direction, which is the feed hole 208 side of the carrier tape 200, and the pin roller main body 34a, and the gap l on the other side in the tape width direction. The gap between the guide block 36R and the pin roller main body 34a may have a dimension equal to or larger than the gap 1 (for example, the dimension of the gap 1+0.5 mm).

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 parts 32L and 32R move the inner surface 38a of the fixed bracket 38 and the inner surface 40d of the side wall part 40b of the movable bracket 40, which function as guides in the tape width direction, to feed the carrier tape 200. 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 that is engaged with the hole 208. As a result, the carrier tape 200 passes below the pin roller 34 with the pin 34c of the pin roller 34 and the feed hole 208 of the carrier tape 200 aligned (guided) in the tape width direction (X-axis direction position). can be done. As a result, the pin 34c of the pin roller 34 can be easily engaged with the feed hole 208 of the carrier tape 200.

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

In the case of this embodiment, the roller main body 34a of the pin roller 34 is supported by a support shaft 44 via a clutch mechanism (one-way clutch) 42 housed 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 walls 40a and 40b of the movable bracket 40, respectively, as shown in FIG.

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

The pin roller 34 restricts movement of the carrier tape 200 on the first sub-tape path P1 in the opposite direction to the tape feeding direction A. That is, by moving the carrier tape 200 on the first sub-tape path P1 in the opposite direction to the tape feeding direction A, unintentional coming off from the main body 12 of the component supply device 10 is suppressed. As a result, the carrier tape 200 can be reliably kept on standby on the first sub-tape path P1. Note that if you want to intentionally pull out the carrier tape 200, by moving the movable bracket 40 provided with the pin roller 34 relatively in the tape thickness direction and moving it away from the carrier tape 200, The engagement between the pin 34c and the feed hole 208 of the carrier tape 200 is disengaged, so that the carrier tape 200 can be easily pulled out as intended.

Further, as shown in FIG. 4, the roller main body 34 of the pin roller 34 is connected to the main surface 204a of the base tape 204 over approximately the entire tape width direction (X-axis direction) of the carrier tape 200 on the first sub-tape path. Although the outer peripheral portions 34b are provided opposite to each other, the embodiment of the present invention is not limited thereto. For example, the outer peripheral portion 34b of the roller main body portion 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 a sprocket, the roller main body portion 34a may have a minimum size in the tape width direction (X-axis direction) that allows formation of 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 this embodiment is configured to use the first sub-tape path P1 when loading the carrier tape 200 into the main body 12 of the component supply device 10. For example, as shown in FIG. 3, when loading the carrier tape 200 (i.e., the preceding carrier tape 200A) into the main body 12 of the component supply device 10 in which no carrier tape 200 has been loaded, the first secondary Tape path P1 is used. For example, when a carrier tape 200 (following carrier tape 200B) following a carrier tape 200 (preceding carrier tape 200A) that has already been put into the main body 12 of the parts supplying apparatus 10 is fed into the main body 12 of the parts feeding apparatus 10. In this case, the first sub-tape path P1 is used.

As shown in FIG. 3, the carrier tape 200 (preceding carrier tape 200A) is placed on the first sub-tape path P1, for example, manually by an operator. Specifically, first, the front end of the carrier tape 200 (preceding carrier tape 200A) in the tape feeding direction A is placed on the guide blocks 36L, 36R of the first and second tape guide sections 32L, 32R of the tape holding unit 30. will be placed in

The carrier tape 200 (preceding carrier tape 200
A) is manually fed in the tape feeding direction A by an operator. The carrier tape 200 (preceding carrier tape 200A) sent in the tape feeding direction A by the operator enters between the tape guides 36L, 36R and the pin roller 34 (gap l), and the feed hole 208 is inserted into the pin of the pin roller 34. 34c. When the feed hole 208 engages with the pin 34c of the pin roller 34, the carrier tape 200 (preceding carrier tape 200A) will not come off unintentionally from the component supply device 10.

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

The carrier tape 200 (preceding carrier tape 200A) that has passed through the input port 12a is reliably fed in the tape feeding direction A even if it is a thin carrier tape by the rotation of the pin roller 34 manually by the operator. The tape moves toward the sprocket 14 located furthest upstream in the tape feeding direction A along the tape path P0.

As shown in FIG. 6, when the feed holes 208 of the carrier tape 200 (preceding carrier tape 200A) engage with the teeth 14a of the sprocket 14, tape feeding by the pin roller 34 is completed. For example, when an operator presses a button such as a "tape set completion button", a sensor detects that the carrier tape 200 has reached the position on the main tape path P0 where the feed hole 208 engages the teeth 14a of the sprocket 14. (not shown), and further, for example, by detecting the start of rotation of the sprocket 14 by the moving carrier tape 200 due to the rotation of the pin roller 34, the carrier tape 200 (preceding carrier tape 200A) is attached to the tooth 14a. The sprocket 14 engaged with the feed hole 208 begins to rotate.

As the sprocket 14 rotates, the carrier tape 200 (preceding carrier tape 200A) is sent toward the sprocket 16 located further downstream in the tape feeding direction A along the main tape path P0, as shown in FIG. When the feed holes 208 of the carrier tape 200 (preceding carrier tape 200A) engage with the teeth 16a of the sprocket 16, the sprocket 14 stops rotating and is in a free rotation state where it can freely rotate (the motor driving the sprocket 14 (not shown) (2) is de-energized.

As shown in FIG. 1, the top tape 206 of the carrier tape 200 (preceding carrier tape 200A) sent in the tape feeding direction A by the sprocket 16 is peeled off by the cutting edge 20a of the top tape peeling section 20 at the top tape peeling position Q1. Then, the feed hole 208 engages with the teeth 18a of the sprocket 18 located between the top tape peeling section 20 and the component supply position Q1. Then, the carrier tape 200 (preceding carrier tape 200A) is sent by the two sprockets 16 and 18 in the tape feeding direction A toward the component supply position Q1.

As shown in FIG. 1, the carrier tape 200 (preceding carrier tape 200A) sent in the tape feeding direction A by the two sprockets 16 and 18 is placed against 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.

At any timing while the preceding carrier tape 200 is supplying components to the nozzle 102 of the transfer head 100 of the component mounting apparatus, a subsequent carrier scheduled to supply the next component following the preceding carrier tape 200A Tape 200B is placed on main body portion 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 leading carrier tape 200A is moved to the vacated first sub-tape path P1. A subsequent carrier tape 200B is placed. This will be explained.

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 rotating the movable bracket 40 of the tape holding unit 30 about the rotation center line C1.

As shown in FIG. 6, from a state in which the preceding carrier tape 200A is moving in the tape feeding direction A on the first sub-tape path P1, an operator moves the movable bracket 40 of the tape holding unit 30 around the rotation center line C1. Swirl as follows.

As shown in FIG. 7, due to the rotation of the movable bracket 40 of the tape holding unit 30 disposed on the main surface 204a side of the preceding carrier tape 200A, the pin roller 34 supported by the movable bracket 40 and the second tape guide section 32R rises, that is, moves in a direction 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 rises due to the rotation of the movable bracket 40 of the tape holding unit 30, the first tape guide portion 32L (guide block 36L) of the fixed bracket 38 moves in the tape thickness direction (Z-axis direction) relative to the pin roller 34. move away from each other. As a result, 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. It is relatively retracted from inside 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 body portion 34a of the pin roller 34. be put into a state.

Further, when the second tape guide portion 32R (guide block 36R) rises in a direction away from the main surface 204a side of the preceding carrier tape 200A due to the rotation 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. As a result, the preceding carrier tape 200A is partially twisted (in FIG. 7, the dotted line indicates the preceding carrier tape 200A before being twisted). Specifically, the preceding carrier tape 200A rotates around the second tape guide portion 32R, and the portion near the second tape guide portion 32R (guide block 36R) is twisted more than the other portions.

As shown in FIG. 7, from the state where the preceding carrier tape 200A is twisted so that the other side in the tape width direction, which is the side opposite to the feed hole 208 side, is lifted, the second tape guide portion 32R (guide block 36R) of the movable bracket 40 is ) rises, 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 untwisting.

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, which is the side opposite to the feed hole 208 side, is the second tape guide portion 32R. When the leading carrier tape 200A loses the support of the second tape guide portion 32R (guide block 36R), the leading carrier tape 200A falls downward. That is, the preceding carrier tape 200A on the first sub-tape path P1 passes between the first and second tape guide parts 32L and 32R, and the leading carrier tape 200A on the first sub-tape path P1 passes between the first and second tape guide parts 32L and 32R, and It moves toward the sub tape path P2. As a result, 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 the first and second tape guide sections 32L and 32R (guide blocks) of the tape holding unit 30. 36L and 36R) will be explained below.

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 moving the carrier tape 200 from above the first sub tape path P1 to the second sub tape path P2 located below it, the carrier tape 200 is located between the first and second sub tape paths P1 and P2. 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 is provided for the carrier tape 200 to bypass such one guide member, it is necessary to inevitably increase the size of the component supply device 10 in the tape width direction (X-axis direction). As a result, the number of component supply devices 10 that are mounted on one component mounting device in a state where they are closely arranged in the tape width direction (X-axis direction) is reduced.

On the other hand, as shown in FIG. 4, the carrier tape 200 on the first sub-tape path P1 is divided into first and second tape guide parts 32L and 32R (guide block 36L, 36R) guides (supports) from below both ends in the tape width direction, when moving the carrier tape 200 from above the first sub tape path P1 to the second sub tape path P2 located below the first sub tape path P1, The carrier tape 200 can easily pass between the first and second tape guide parts 32L and 32R. That is, the carrier tape 200 can be moved from above the first sub-tape path P1 to onto the second sub-tape path P2 below it, without significantly changing the position in the tape width direction (position in the X-axis direction). Therefore, the size of the component supply device 10 in the tape width direction (X-axis direction) can be reduced.

Note that when the pin roller 34 rises due to the rotation of the movable bracket 40 of the tape holding unit 30, the pin 34c moves the tape from within the feed hole 208 of the carrier tape 200 (preceding carrier tape 200A) on the first sub-tape path P1. It is preferable to reliably retract (disengage) in the thickness direction (Z-axis direction).

In the case of this embodiment, as shown in FIG. 7, the pin roller 34 is moved in the tape thickness direction (Z-axis direction) from within the feed hole 208 of the carrier tape 200 (preceding carrier tape 200A) on the first sub-tape path P1. When the pin 34c rises and retracts, 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 moves in the tape width direction (X-axis direction) of the carrier tape on the feed hole 208 side. ) has a tape pressing part 46 that presses one side of the tape.

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

When the pin roller 34 and the second tape guide section 32R rise due to the rotation of the movable bracket 40 of the tape holding unit 30, the tape pressing section 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 holes 208 of the carrier tape 200 (preceding carrier tape 200A). That is, together with the pin roller 34 and the second tape guide section 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 of the carrier tape 200 (preceding carrier tape 200A) to the upper side by the rotation of the movable bracket 40 of the tape holding unit 30, the movable bracket 40 By turning in the opposite direction, the carrier tape 200 (preceding carrier tape 200A) may be pushed downward toward the second sub-tape path P2 by the second tape guide portion 32R. This is, for example, when the carrier tape 200 (preceding carrier tape 200A) is difficult to fall by itself after the second tape guide portion 32R moves from the lower side of the carrier tape 200 (preceding carrier tape 200A) to the upper side. This is useful (for example in the case of carrier tapes with large tape thicknesses).

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 subsequent carrier tape 200B is moved to the vacant first sub-tape path P1. It becomes possible to place.

Similar to the preceding carrier tape 200A, the trailing carrier tape 200B has its front end in the tape feeding direction aligned with the guide block 36L of the first and second tape guide sections 32L and 32R of the tape holding unit 30 by manual operation of the operator. , 36R. The subsequent carrier tape 200B placed on the guide blocks 36L and 36R passes below the pin roller 34 by manual tape feeding in the tape feeding direction A by the operator, and is inserted into the pin 34c of the pin roller 34 through the feed hole 208. is engaged. Thereby, the succeeding carrier tape 200B can reliably stand by on the first sub-tape path P1 without coming off unintentionally.

Note that the component supply device 10 of the present embodiment supplies the first sub tape following the preceding carrier tape 200A that is being 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 automatically starts feeding the subsequent carrier tape 200B waiting on the path P1.

First, in order to automatically start feeding the succeeding carrier tape 200B by the automatic tape feeding mechanism 50, as shown in FIG. The subsequent carrier tape 200B waits while entering 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 put into the main tape path P0 from the first sub tape path P1.

Further, the front end 210B of the trailing carrier tape 200B that has entered the main tape path P0 in the tape feeding direction A is connected to the leading edge 210B that is being fed in the tape feeding direction A along the second sub-tape path P2 and the first sub-tape path P1. The subsequent carrier tape 200B waits in a state overlapping the carrier tape 200A.

For this purpose, an upper guide surface 12c of the main body section 12 is arranged above and opposed to the carrier tape 200 on the main tape path P0, and a lower guide surface 12d is arranged below and opposed to the carrier tape 200. In the vicinity of the tape input port 12a, a gap is provided through which two carrier tapes 200 overlapping in the tape thickness direction can pass.

As shown in FIG. 11, the automatic tape feeding mechanism 50 has a sprocket 14 disposed at the most upstream side in the tape feeding direction A, and an urging force that urges the carrier tape 200 on the main tape path P0 toward the sprocket 14. It has a block 52 and a stopper 54 for waiting the subsequent carrier tape 200B.

The biasing block 52 of the automatic tape feeding mechanism 50 is arranged to face the sprocket 14 across the main tape path P0, and is located on the main tape path P0 (i.e., the upper guide surface 12c and the lower guide surface 12d of the main body 12). The carrier tape 200 (disposed between the sprocket 14 and the sprocket 14) is configured to urge the carrier tape 200 toward the sprocket 14. Specifically, as shown in FIG. 3, the biasing block 52 is movable toward the sprocket 14 from the lower guide surface 12d, and is biased toward the sprocket 14 by an unillustrated biasing member (for example, a spring). energized. The two-dot chain line in FIG. 3 indicates the biasing block 52 in a retracted state from the lower guide surface 12d.

On the other hand, the teeth 14a of the sprocket 14 facing the biasing block 52 protrude toward the biasing block 52 from the upper guide surface 12c, 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 biasing block 52 and comes into contact with the upper guide surface 12c, so that the feed hole 208 contacts the tooth 14a of the sprocket 14. engage.

Note that when the preceding carrier tape 200A and the succeeding carrier tape 200B are present in an overlapping state between the biasing block 52 and the sprocket 14, the teeth 14a of the sprocket 14 are engaged with the feed holes 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 12 toward the lower guide surface 12d.

As shown in FIG. 11, the leading carrier tape 200A is being fed in the tape feeding direction A by the sprocket 16 (or sprockets 16, 18) (see FIG. 1) along the second secondary 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 that overlaps therewith. As a result, the movement of the preceding carrier tape 200A in the tape feeding direction A and the movement of the succeeding carrier tape 200B toward the component supply position Q1 are suppressed.

When the carrier tape 200 is not present between the biasing block 52 and the sprocket 14, or when only one carrier tape 200 is present, the tape locking portion 54a of the stopper 54, as shown in FIGS. 3 and 6, It is set back from the upper guide surface 12c.

Note that, for example, the tape locking portion 54a of the stopper 54 moves back and forth in conjunction with the movement of the biasing block 52. For example, the biasing block 52 is lowered to the position where two carrier tapes 200 are present between the biasing block 54 and the sprocket 14, so that the tape locking portion 54a of the stopper 54 is moved downward from the upper guide surface 12c. stand out.

By having such an automatic tape feeding mechanism 50 in the component supply device 10, 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. The carrier tape 200A can be automatically fed following the preceding carrier tape 200A being fed in the tape feeding direction A along the tape feed direction A.

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

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

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 However, the embodiments of the present invention are not limited to this.

For example, in the case of the tape holding section 130 of the component supply device according to another embodiment, as shown in FIG. The end is shifted downstream in the tape feeding direction A compared to the upstream end in the tape feeding direction A of the first tape guide section 132L (the guide block 36L supported by it). Thereby, the carrier tape 200 on the first sub-tape path P1 can easily pass between the first and second tape guide parts 132L and 132R in the tape thickness direction (vertical direction), and the first sub-tape The tape easily falls (moves) to the second sub-tape path P2 located below the path P1 (compared to the case where the first and second tape guide parts 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 parts 32L and 32R of the tape holding unit 30 toward the second sub-tape path P2. As such, at least one of the first and second tape guide parts 32L and 32R may be made of a material that can be elastically deformed in the tape width direction (X-axis direction). For example, in the case of the embodiment described above, 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 subsequent carrier tape 200B waiting on the first sub-tape path P1 is placed next to 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 the tape is not limited to the automatic tape feeding mechanism of the above-described embodiment.

For example, another form of automatic tape feeding mechanism detects the trailing edge of the leading carrier tape 200A in the tape feeding direction A that is being fed in the tape feeding direction along the second sub-tape path P2 and the main tape path P0. , a sensor (not shown) provided at the tape input port 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 input port 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 device 10 of the above-described embodiment, the movement of the preceding carrier tape 200A from above the first sub-tape path P1 to the second sub-tape path P2 below it requires the movement of the tape holding unit 30. This is done by manually pivoting the bracket 40. Alternatively, a drive source such as a motor may rotate the movable bracket 40.

In addition, in the case of the above-described embodiment, the rotation of the movable bracket 40 of the tape holding unit 30 causes the pin 34c to be inserted into the feed hole 208 of the preceding carrier tape 200A on the first sub-tape path P1, as shown in FIG. A second tape guide portion 32R (guide block 36R) guides the other side of the preceding carrier tape 200A in the tape width direction (X-axis direction) on the side opposite to the feed hole 208 from below together with the pin roller 34 engaged with the pin roller 34. ) increases. However, the embodiments of the present invention are not limited to this.

The component supply device of another embodiment is configured such that only the pin roller 34 is separated upward from the preceding carrier tape 200A on the first sub-tape path P1. For example, by moving the pin roller 34, the operator retracts the pin 34c of the pin roller 34 from within the feed hole 208 of the preceding carrier tape 200A. Next, the operator grabs the leading carrier tape 200A, passes the gripped leading carrier tape 200A between the first and second tape guide parts 32L and 32R, and places it on the second sub-tape path P2. . This completes the movement of the preceding carrier tape 200A from the first sub-tape path P1 to the second sub-tape path P2 located below.

That is, in a broad sense, the present invention sequentially feeds a preceding carrier tape and a succeeding carrier tape that house parts and have a plurality of feed holes arranged in the longitudinal direction of the tape to a parts supply position, and A component supply device that supplies components to a transfer head of a component mounting device includes a main body portion, a tape path formed in the main body portion and guiding a carrier tape to the component supply position, and a tape path formed in the main body portion and the tape path formed in the main body portion to guide a carrier tape to the component supply position. The opening is provided on the upstream side in the feeding direction from an opening provided on the upstream end side in the feeding direction of the carrier tape in the tape path, and is configured to move the subsequent carrier tape upward from the preceding carrier tape existing in the tape path. a tape holding unit that holds the following carrier tape at a position apart from the first tape guide portion that supports the lower surface of one side of the subsequent carrier tape; and a second tape guide section supporting a lower surface of the side, the second tape guide section being provided movably relative to the first tape guide section. .

In the present invention, while the carrier tape is being fed along the tape path, the cutting edge of the top tape peeling section disposed on the tape path enters between the base tape and the top tape from the front end side of the carrier tape in the tape feeding direction. The present invention is applicable to any component supply device that at least partially peels off the top tape from the base tape.
