  4, 5, and 6 (a), the main body 31 includes a travel path 41 of the carrier tape 17. The travel path 41 extends from the rear of the main body 31 toward the front. An introduction path 42 is provided on the entrance side (rear end side) in the traveling path 41 of the main body 31. The introduction path 42 is provided so as to extend along the traveling path 41 above the traveling path 41. The introduction path 42 is formed by a pair of tape support portions 43 that protrude and extend in the Y-axis direction and support both ends in the width direction of the carrier tape 17 (FIG. 6B). The feed sprocket 32 is provided at the rear of the main body 31 so as to face the introduction path 42 from above.

  In FIG. 4, the feed sprocket 32 is driven by a feed sprocket drive motor 32 </ b> M provided in the main body 31. The feed sprocket 32 is attached to the drive shaft of the feed sprocket drive motor 32M via a one-way clutch. In the one-way clutch, when the drive shaft of the feed sprocket drive motor 32M rotates in a direction for moving the lower end of the feed sprocket 32 forward (arrow R shown in FIG. 4; referred to as a tape feed direction), the rotation is fed to the feed sprocket 32. When the rotation of the drive shaft is stopped, free rotation of the feed sprocket 32 in the tape feed direction with respect to the drive shaft is allowed.

(FIG. 4). When the leading portion of the carrier tape 17 entering the introduction path 42 reaches the feed sprocket 32, the outer peripheral teeth of the feed sprocket 32 engage with the feed hole 24 of the carrier tape 17 from above, and the feed sprocket 32 moves in the tape feeding direction. Rotated. At this time, when the rotation sensor 44 detects that the feed sprocket 32 has rotated a predetermined amount or more, the feed sprocket drive motor 32M starts to rotate the feed sprocket 32, and the carrier tape 17 moves from the introduction path 42 to the travel path 41. Sent out.

  In FIG. 4, the sub sprocket 33 and the main sprocket 34 are provided on the front upper part of the main body 31 so as to face the traveling path 41 from below. The sub sprocket 33 is driven by a sub sprocket drive motor 33M provided in the main body 31, and the main sprocket 34 is driven by a main sprocket drive motor 34M provided in the main body 31. The sub sprocket drive motor 33M rotates the sub sprocket 33 in a direction to move the upper end of the sub sprocket 33 forward, and the main sprocket drive motor 34M rotates the main sprocket 34 in a direction to move the upper end of the main sprocket 34 forward. Let

  In FIG. 4, a traveling tape detection sensor 45 is provided along the traveling path 41. The traveling tape detection sensor 45 detects a state in which the leading and trailing ends of the carrier tape 17 traveling in the traveling path 41 have passed a predetermined reference position (here, the position where the traveling tape detection sensor 45 is provided). The running tape detection sensor 45 detects the position of the leading portion of the carrier tape 17 by counting the number of the component storage portions 23 that have passed the reference position.

  When the traveling tape detection sensor 45 detects that the carrier tape 17 sent through the traveling path 41 by the rotation of the feed sprocket 32 has reached the reference position, the subsidiary sprocket 33 is driven by the subsidiary sprocket drive motor 33M. The main sprocket 34 is driven by the main sprocket drive motor 34M. When the carrier tape 17 sent through the travel path 41 reaches the sub sprocket 33, the sub sprocket 33 pitches the carrier tape 17 forward by engaging the outer peripheral teeth with the feed holes 24 of the carrier tape 17 from below. . The main sprocket 34 pitches the carrier tape 17 forward by engaging the outer peripheral teeth with the feed holes 24 of the carrier tape 17 sent by the sub sprocket 33 from below.

  4 and 7 (a) and 7 (b), the tape guide 35 is provided on the front upper portion of the main body 31 at a position covering the sub sprocket 33 and the main sprocket 34 from above. A front part of the tape guide 35 is provided with a part take-out opening 35K for taking out the part PT located at the part supply position 16K by the carrier tape 17 by the suction nozzle 13a.

  4 and 7A and 7B, the peeling member 36 is attached to the tape guide 35. The peeling member 36 has a tip 36 </ b> H extending obliquely downward located at a position between the base tape 21 and the cover tape 22 of the carrier tape 17 that travels on the travel path 41, and the sub sprocket 33 moves to the main sprocket 34. When the carrier tape 17 is fed toward the base tape 21, the leading end 36 </ b> H of the peeling member 36 enters (interrupts) between the base tape 21 and the cover tape 22, and the cover tape 22 is peeled from the base tape 21. The peeled cover tape 22 advances forward with the base tape 21 while being rolled or crushed in the width direction, and is discharged from the front end of the tape guide 35.

  When the main sprocket 34 rotates to advance the carrier tape 17 forward, the component storage portion 23 from which the cover tape 22 has been peeled off by the peeling member 36 reaches the component supply position 16K, and the component PT reaches the component supply position 16K. Supplied. The component PT supplied to the component supply position 16K is sucked (pickup) through the component take-out opening 35K by the suction nozzle 13a located above the component PT.

  As described above, in the present embodiment, the main sprocket 34 is engaged with the carrier tape 17 in the traveling path 41 and rotates, thereby pitch-feeding the carrier tape 17 and bringing the component PT to the predetermined component supply position 16K. It comes to supply. When the carrier tape 17 is pitch-fed by the main sprocket 34, the rotation of the feed sprocket 32 by the feed sprocket drive motor 32M and the rotation of the sub sprocket 33 by the sub sprocket drive motor 33M are stopped.

  4 and 8, the region between the pair of tape support portions 43 projecting and extending in the Y-axis direction in the traveling path 41 is a portion in the introduction path 42 of the carrier tape 17 engaged with the main sprocket 34. This is a passage (referred to as a movement passage 46) when moving the pipe below the introduction passage 42. When the carrier tape 17 supported at both ends of the carrier tape 17 (base tape 21) by the pair of tape support portions 43 is twisted to be inclined from the horizontal posture, the carrier tape 17 falls through the moving passage 46. The lower surface of the carrier tape 17 (here, the lower surface of each embossed component storage portion 23) is supported by the tape support surface 47 that forms the lower surface of the travel path 41. The carrier tape 17 falling from the introduction path 42 is disengaged from the outer peripheral teeth of the feed sprocket 32 in the process, the introduction path 42 is opened, and the carrier tape 17 can be newly inserted from the introduction path 42. .

  4, 5, 6 </ b> A, and 8, the guide portion 37 includes a bracket portion 51 and a wheel portion 52. The bracket portion 51 is swingably supported by horizontal swing shafts 53 supported at both ends by the main body portion 31. The wheel portion 52 is attached to the bracket portion 51 so as to be rotatable around a rotation shaft 54 attached in a horizontal posture. On the outer periphery of the wheel portion 52, a plurality of retaining pins 52P are provided at regular intervals.

  6A and 8, the bracket portion 51 is provided with a claw portion 56 that protrudes horizontally and extends. The bracket portion 51 is swingable about the swing shaft 53 between an initial position (position shown in FIG. 6A) and an upper position where the wheel portion 52 is moved upward from the initial position.

  5 and 8, a protrusion 57 is provided at a position facing the claw 56 of the main body 31 in the X-axis direction. In a state where the bracket portion 51 is located at the initial position, the claw portion 56 and the projection portion 57 are located facing each other in the horizontal direction. The claw portion 56 and the projection portion 57 form an insertion port 37K of the carrier tape 17. A contact protrusion 58 is provided at a position above the protrusion 57 of the main body 31.

  When the carrier tape 17 is inserted from the insertion slot 37K with the bracket portion 51 positioned at the initial position, both ends of the base tape 21 are supported from below by the claw portion 56 and the projection portion 57, And it is guided and enters into the introduction path 42. The carrier tape 17 with the base tape 21 supported by the claw portion 56 and the projection portion 57 is engaged with the retaining pin 52P of the wheel portion 52 in the feed hole 24 and advances forward while rotating the wheel portion 52.

  The wheel portion 52 is allowed to rotate only in the insertion direction of the carrier tape 17 by a one-way clutch (not shown). For this reason, after the carrier tape 17 enters the introduction path 42, the carrier tape 17 is dropped from the tape path 60 between the claw 56 and the protrusion 57, and the carrier tape 17 and the retaining pin 52P are engaged. As long as is not removed, the carrier tape 17 cannot be pulled out from the introduction path 42, and unintentional removal of the carrier tape 17 from the introduction path 42 is prevented.

  4 and 6A, a stopper member 61 and a standby tape detection sensor 62 are provided at a position slightly ahead of the feed sprocket 32 of the main body 31. The stopper member 61 projects into the introduction path 42 when the preceding carrier tape 17 (referred to as the preceding carrier tape 17 </ b> A) is traveling in the traveling path 41, and the subsequent carrier tape 17 ( The following carrier tape 17B is in contact with the leading portion of the carrier tape 17B) to prevent the subsequent carrier tape 17B from proceeding further, and the subsequent carrier tape 17B is put into a standby state. At this time, the feed sprocket 32 does not rotate by an amount necessary to start the feeding operation of the carrier tape 17, and the carrier tape 17 is not fed by the feed sprocket 32 and maintains a standby state. The standby tape detection sensor 62 detects the subsequent carrier tape 17B that is in contact with the stopper member 61 and is in a standby state.

  When the carrier tape 17 is newly attached to the tape feeder 16, the operator OP inserts the carrier tape 17 from the insertion port 37K. The carrier tape 17 inserted from the insertion port 37K advances while being inserted into the feed hole 24 into a retaining pin 52P provided in the wheel portion 52, enters the introduction path 42, and engages with the feed sprocket 32. At this time, the carrier tape 17 advances without coming into contact with the stopper member 61 and rotates the feed sprocket 32 by a predetermined rotation or more. Therefore, the feed sprocket 32 starts rotating and feeds the carrier tape 17 (arrow A shown in FIG. 9A), and the carrier tape 17 engages with the main sprocket 34.

  When the control unit 38 detects that the carrier tape 17 is engaged with the main sprocket 34 based on the detection information from the running tape detection sensor 45, the control unit 38 notifies the fact through a notifying means (not shown) provided in the component mounting apparatus 3. The operator OP is notified. Upon receiving this notification, the operator OP swings the bracket portion 51 around the swing shaft 53 (arrow B1 shown in FIG. 9B) and positions it in the upper position.

  By the movement (swinging) of the bracket portion 51, the carrier tape 17 is pulled up by the claw portion 56 (FIG. 9B and FIG. 10A). The arrow C1 shown in FIG. In this process, one end side of the carrier tape 17 (base tape 21) comes into contact with the contact protrusion 58 from below, so that the carrier tape 17 is twisted and tilted obliquely (FIG. 10 (b) → FIG. 10 (c)). 9 (b)), the carrier tape 17 falls downward through the tape passage 60 and the moving passage 46 (FIG. 10 (c) and FIG. 11 (a). The arrow shown in FIG. 10 (c)). C2). As a result, the feed hole 24 of the carrier tape 17 is disengaged from the outer peripheral teeth of the feed sprocket 32 and the carrier tape 17 and the feed sprocket 32 are disengaged.

  When the carrier tape 17 falls through the tape passage 60 and the moving passage 46, the operator OP swings the bracket portion 51 in the reverse direction (arrow B2 shown in FIG. 11A), and the guide portion 37 is initialized. Return to position. As a result, the introduction path 42 is opened, and the carrier tape 17 can be newly inserted from the guide portion 37.

  As described above, in this embodiment, when the portion in the introduction path 42 of the carrier tape 17 engaged with the main sprocket 34 is moved below the introduction path 42, the engagement of the carrier tape 17 with the feed sprocket 32 is released. The introduction path 42 is opened.

  When the guide unit 37 is returned to the initial position, the operator OP inserts the subsequent carrier tape 17B from the insertion port 37K. The succeeding carrier tape 17B inserted from the insertion port 37K enters the introduction path 42 and advances through the introduction path 42, and engages with the outer peripheral teeth of the feed sprocket 32. At this time, since the preceding carrier tape 17A is present in the traveling path 41, the stopper member 61 protrudes into the introduction path 42 to prevent the subsequent carrier tape 17B from proceeding, and the subsequent carrier tape 17B enters a standby state (FIG. 11B). ).

  When the terminal portion of the preceding carrier tape 17A traveling on the traveling path 41 advances forward beyond the stopper member 61, the stopper member 61 is retracted from the introduction path 42 to release the blocking of the subsequent carrier tape 17B. When the standby tape detection sensor 62 detects that the standby state of the subsequent carrier tape 17B has been released, the control unit 38 rotates the feed sprocket 32. Thus, the subsequent carrier tape 17B follows the preceding carrier tape 17A and travels on the travel path 41, and then engages with the main sprocket 34.

  In the tape feeder 16 in the present embodiment, when the succeeding carrier tape 17B is inserted from the introduction path 42, the succeeding carrier tape 17B does not overlap with the preceding carrier tape 17A and does not press against each other. For this reason, even if the succeeding carrier tape 17B is attached and kept waiting while the preceding carrier tape 17A is being used, smooth running is not hindered by friction between the preceding carrier tape 17A and the succeeding carrier tape 17B. Further, when the carrier tape 17 is of an embossed type as in the case of the present embodiment, there is no possibility that the component storage unit 23 is crushed.

  In the above-described embodiment, the carrier tape 17 moved to the lower side of the introduction path 42 is supported by the tape support surface 47 provided in the main body portion 31 on the lower surface of each component storage portion 23. 12 and 13, the tape support surface 47 is formed in a groove shape with a depressed central portion, so that both ends of the base tape 21 support the tape instead of the lower surface of the component storage portion 23. It can be supported by surface 47. If it does in this way, the frictional force which the carrier tape 17 receives from the main-body part 31 side at the time of the driving | running | working of the carrier tape 17 can be reduced, and it becomes possible to drive the carrier tape 17 more smoothly.

  As described above, in the tape feeder 16 according to the present embodiment, the main body portion 31 includes the introduction path 42 into which the carrier tape 17 is inserted and the travel path 41 connected thereto, and is provided in the main body section 31. The feed sprocket 32 feeds the carrier tape 17 inserted into the introduction path 42 to the traveling path 41. Then, the part of the carrier tape 17 engaged with the main sprocket 34 in the introduction path 42 is moved below the introduction path 42 to disengage the carrier tape 17 and the feed sprocket 32, thereby The succeeding carrier tape 17B can be inserted from the introduction path 42 by opening. Therefore, the subsequent carrier tape 17B inserted into the introduction path 42 does not overlap the preceding carrier tape 17A in the traveling path 41, and the preceding carrier tape 17A does not receive friction with the subsequent carrier tape 17B. Therefore, even when the subsequent carrier tape 17B is in the standby state, the preceding carrier tape 17A can be smoothly run.

  As a result, the supply of the parts PT by the tape feeder 16 is surely performed. For this reason, the efficiency of mounting the component PT on the substrate PB by the component mounting apparatus 3 can be improved, and the production efficiency of the mounting substrate JK manufactured by the component mounting line 1 can be improved.

  In the above-described embodiment, the case where the carrier tape 17 is an embossed type has been described as an example. However, even when the carrier tape 17 is a simple tape shape that is not an embossed type, the same effect is obtained. Can be obtained.

  Provided are a tape feeder and a mounting board manufacturing method capable of smoothly running a preceding carrier tape even when the subsequent carrier tape is in a standby state.
