Next, the configuration of the tape peeling device 70 will be described with reference to FIGS. As shown in FIG. 7, a tape peeling device 70 is attached to the top end of the feeder 21 to peel off one end side of the cover tape 902 of the carrier tape 900 sent to the component supply position 21a.

The tape peeling device 70 is provided in a main body 71 that is detachably attached to the feeder main body 21b. As shown in FIG. 8, the main body 71 has a U-shaped cross-section opened downward, and the front and rear sides of both

side walls

71a and 71b of the main body 71 are fixed to both side surfaces of the feeder main body 21b by fastening means such as screws. The Then, the carrier tape 900 is guided between the

side walls

71 a and 71 b of the main body 71. On the upper wall 71c of the main body 71, a notch 71c1 is formed at a predetermined position including the component supply position 21a so that components can be taken out from the component storage portion 901a of the carrier tape 900.

A cutter member 72 for cutting the cover tape 902 is attached to the upper wall 71c of the main body 71 prior to peeling the cover tape 902 by a peeling member 75 described later. The cutter member 72 is integrally held by a holding bracket 73 that is detachably fixed to the upper wall 71c with bolts or the like with the cutting edge 72a facing downward. The cutting edge 72 a of the cutter member 72 passes through the upper wall 71 c of the main body 71 and enters the conveyance path of the carrier tape 900.

As shown in FIGS. 2 and 3, the cutter member 72 is disposed so as to cut in the longitudinal direction of the tape between an adhesive portion 902a for bonding one end of the cover tape 902 and the component storage portion 901a. . That is, the cover tape 902 is cut inside the adhesive portion 902a at a position offset by a predetermined amount S1 from the opening of the component storage portion 901a to the opposite side of the sprocket hole 901b. 902c of FIG.2 and FIG.3 shows the cut surface (cut | notch part) of the cover tape 902 cut | disconnected.

On the upper wall 71c of the main body 71, a plate-like peeling member 75 having a tongue 75a having a sharp tip that peels off the end of the cover tape 902 cut by the cutter member 72 from the carrier tape 900 is provided as a notch. It is fixed at an upper position of the carrier tape 900 so as to cover 71c1. As shown in FIG. 2, the tongue portion 75 a is disposed at a position spaced apart from the cutting edge 72 a of the cutter member 72 by a predetermined amount S <b> 2 in the feed direction of the carrier tape 900 (the arrow direction in FIG. 2).

The tongue 75a of the peeling member 75 is inserted between the end of the cover tape 902 cut by the cutter member 72 on the component storage portion 901a side and the base tape 901, and the end of the cover tape 902 by the tongue 75a. Is peeled off.

Further, as shown in FIG. 7, a folding member 76 is attached integrally to the peeling member 75 so that the end of the peeled cover tape 902 is folded back toward the sprocket hole 901 b, and the folding member 76 and the carrier tape 900 are attached. A slight gap is formed between the upper surface. An inclined surface 76 a that is inclined in the width direction of the cover tape 902 is formed on the folded member 76 over a predetermined length along the feed direction of the carrier tape 900. The inclined surface 76 a of the folding member 73 protrudes in the width direction of the cover tape 902 with respect to the tongue portion 75 a of the peeling member 75.

The folding member 76 folds the end portion of the cover tape 902 peeled off by the tongue portion 75a of the peeling member 75 toward the sprocket hole 901b side while gradually rising up by the inclined surface 76a, and removes the component supplied to the component supply position 21a. The upper surface of the stored component storage unit 901a is opened (exposed). The cover tape 902 folded back by the inclined surface 76a of the folding member 76 is forcibly pushed into the gap between the folding member 76 and the upper surface of the carrier tape 900 (base tape 901) as shown in FIG. The open state of the upper surface of the storage unit 901a is maintained.

At this time, the other end side of the cover tape 902 bonded by the bonding portion 902b remains on the carrier tape 900 as shown in FIG.

The feeder 21 including the tape peeling device 70 having the above-described configuration is set in the component supply unit 20 (see FIG. 1), and the feeder 21 side from the main body side of the component mounter 100 via the communication connector 80 (see FIG. 7). Is supplied with power, and necessary information such as a feeder ID is transmitted from the feeder 21 side to the main body side of the component mounting machine 100.

When the carrier tape 900 is fed by the

sprockets

61 and 62, the cover tape 902 is first cut between the component storage portion 901a and one adhesive portion 902a by the cutting edge 72a of the cutter member 72 of the tape peeling device 70. The Next, the tongue portion 75a of the peeling member 75 is inserted between the cut end portion of the base tape 901 and the upper surface of the cover tape 902, and peels off (turns) the end portion of the cover tape 902, and the sprocket hole 901b. Wrap to the side.

At this time, since the position of the cover tape 902 that is wound by the tongue 75a is not the adhesive portion 902a (902b), the conventional peeling resistance does not occur, and the cover tape 902 can be wound with almost no resistance. Further, since the upper surface of the base tape 901 caused by peeling off the bonding portion 902a (902b) does not fluff, the components taken out from the component storage portion 901a are not caught by the fluff.

In addition, the position where the cut surface (cut portion) 902c is formed in the cover tape 902 is not on the component storage portion 901a, but is a position offset from the component storage portion 901a toward the end of the carrier tape 900. There is no fear of damaging the components in the component storage portion 901a by 72.

Further, when the cover tape 902 is folded back toward the sprocket hole 901b, the end of the folded cover tape 902 fits within the end region of the carrier tape 900 in which the sprocket hole 901b is formed as shown in FIG. It does not protrude from the end of the tape 900. Thereby, the width | variety of the feeder 21 which mounts the carrier tape 900 can be stored in the width | variety equivalent to the carrier tape 900, and the increase in the width dimension of the feeder 21 can be suppressed.

Accordingly, unlike the conventional case, a separate discharge mechanism for folding the cover tape 902 in the direction opposite to the feeding direction of the carrier tape 900 and discharging the cover tape 902 becomes unnecessary, and the cover tape 902 can be discharged integrally with the base tape 901 of the carrier tape 900. It becomes like this. In FIG. 7, reference numeral 74 denotes a guide for discharging the carrier tape 900 together with the cover tape 902, and is fixed to the tip of the feeder main body 21b.

Next, the operation of the feeder 21 will be described. The operator inserts the carrier tape 900 between the insertion recess 32a and the rear end of the rail 38 shown in FIG. Then, the fourth engagement protrusion 64 a is engaged with the sprocket hole 901 b formed at the tip of the inserted carrier tape 900, and the carrier tape 900 is conveyed to the third sprocket 63 by the fourth sprocket 64. Since the fourth engagement protrusion 64a is formed only on a part of the outer periphery of the fourth sprocket 64, the fourth engagement protrusion 64a is engaged with the sprocket hole 901b formed at the tip of the inserted carrier tape 900. When this occurs, the carrier tape 900 intermittently moves to the third sprocket 63 side. For this reason, it is safe because the carrier tape 900 is not suddenly pulled into the third sprocket 63 side.

The leading end of the carrier tape 900 fed downstream by the fourth sprocket 64 enters the lower part of the pressing part 33d from the intrusion part 33b. Then, when the sprocket hole 901 b formed in the leading portion of the carrier tape 900 engages with the third engagement protrusion 63 a, the carrier tape 900 is conveyed to the second sprocket 62 by the third sprocket 63. Since the third engagement protrusion 63a is formed on the entire outer periphery of the third sprocket 63, the carrier tape 900 is transported to the second sprocket 62 side in a short time. The carrier tape 900 is pressed from above by the pressing portion 33d so that the engagement between the sprocket hole 901b and the third engagement protrusion 36a is not released.

The leading end of the carrier tape 900 enters under the levitation preventing member 28 from between the guide portion 28b and the rail 38. The tip of the carrier tape 900 is conveyed to the second sprocket 62 while being prevented from rising from the rail 38 by the levitation preventing member 28.

When the second sensor 66 detects the head of the carrier tape 900 conveyed by the third sprocket 63, the first servo motor 22 and the second servo motor 23 intermittently rotate the sprockets 61 to 64 by the component pitch. When the sprocket hole 901b formed in the leading portion of the carrier tape 900 is engaged with the second engagement protrusion 62a, the carrier tape 900 is sent to the tape peeling device 70 by the second sprocket 62, and the carrier tape 900 is sent by the tape peeling device 70. The cover tape 902 is peeled off. When the sprocket hole 901b formed at the head of the carrier tape 900 is engaged with the first engagement protrusion 61a, the components stored in the carrier tape 900 are sequentially positioned and supplied to the component supply position 21a by the first sprocket 61. Is done.

In the following, the carrier tape 900 that is being transported is referred to as a transport tape 910, and the carrier tape 900 that is waiting is referred to as a standby tape 920, so that the two carrier tapes 900 are distinguished.

When the transport tape 910 is transported by the feeder 21, as shown in FIG. 5, the transport tape 910 presses the contact portion 31 a, and the stopper member 31 resists the biasing force of the spring 36 and stops. 31 c swings in the direction approaching the rail 38, and the rear lower end of the stopper member 31 comes into contact with the upper surface of the transport tape 910.

The operator inserts the standby tape 920 between the insertion recess 32a and the transport tape 910.

And the peeling member 75 that peels off the end portion of the cover tape 902 cut by the step and opens the component storage portion 901a. The cutter member 72 damages the component stored in the component storage portion 901a. The cover tape 902 can be accurately peeled without any problems.

Moreover, since the adhesive portion of the cover tape 902 is not peeled off, there is no problem caused by fluffing on the upper surface of the carrier tape 900 (bottom tape 903) caused by peeling the adhesive portion.

According to the above-described embodiment, since the cover tape 902 is folded back to the sprocket hole 901b side provided in the carrier tape 900, the end of the folded cover tape 902 forms the carrier tape 900 in which the sprocket hole 901b is formed. Of the carrier tape 900 and does not protrude from the end of the carrier tape 900. Thereby, the width | variety of the feeder 21 which mounts the carrier tape 900 can be stored in the width | variety equivalent to the carrier tape 900, and the increase in the width dimension of the feeder 21 can be suppressed.

According to the above-described embodiment, since the cutter member 72 is detachably attached to the upper wall 71c of the feeder main body 21b, the cutter member 72 can be easily replaced when the sharpness of the cutter member 72 decreases. be able to.

In the above-described embodiment, the example in which the cover tape 902 is cut by the cutter member 72 has been described. However, even if the cover tape 902 is not completely cut by the cutter member 72, the cover tape 902 is cut into a predetermined depth. You may make it enter. Even in this case, the cover tape 902 can be peeled off without much resistance by the tongue 75a of the peeling member 75.

In the above-described embodiment, an example in which the peeling member 75 and the folding member 76 are configured as separate members has been described. However, the peeling member 75 and the folding member 76 may be integrally formed.

In the above-described embodiment, the sprocket 61 (62) that engages with the carrier tape 900 and sends the components stored in the carrier tape 900 to the component supply position 21a, and the carrier tape 900 that waits and engages with the carrier tape 900.
