The tape feeder is configured to run a carrier tape containing parts and supply the parts to a predetermined part supply position. The tape feeder engages with the carrier tape running path and the carrier tape in the running path and rotates. And a main sprocket for pitch-feeding the carrier tape.

  As one type of such a tape feeder, an autoload type tape feeder is also known in which an inserted carrier tape is automatically drawn and engaged with a main sprocket. The autoload type tape feeder has a guide part with an insertion port for a carrier tape, and when the carrier tape is inserted from the insertion port of the guide part, the carrier tape is guided by the guide part and enters the traveling path, It is sent by a feed sprocket to engage the main sprocket.

  In such an autoload-type tape feeder, it is possible to insert a succeeding carrier tape (following carrier tape) before the carrier tape that travels in advance (leading carrier tape) is completely fed by the main sprocket. When inserting the subsequent carrier tape, first, the preceding carrier tape is dropped from the insertion port, and the subsequent carrier tape is inserted into the insertion port that has been opened. The subsequent carrier tape guided from the insertion port into the traveling path is placed on the upper side of the preceding carrier tape in the traveling path and is in a standby state, and when the preceding carrier tape is sent, the subsequent carrier tape is sent by the feed sprocket, The vehicle travels in the travel path and engages with the main sprocket (for example, Patent Document 1 below).

  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. To communicate. Further, the one-way clutch allows free rotation in the tape feeding direction with respect to the drive shaft of the feed sprocket 32 in a state where the rotation of the drive shaft is stopped.

  Between the feed sprocket 32 and the drive shaft of the feed sprocket drive motor 32M, a rotation sensor 44 that detects that the feed sprocket 32 has rotated in the feed direction of the carrier tape 17 with the drive shaft stopped is provided. (FIG. 4). When the leading portion of the carrier tape 17 entering the travel path 41 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 certain amount or more, the feed sprocket drive motor 32M starts to rotate the feed sprocket 32, and the carrier tape 17 advances forward in the travel path 41. To do.

  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 auxiliary sprocket drive motor 33M rotates the auxiliary sprocket 33 by a pitch in a direction in which the upper end of the auxiliary sprocket 33 is moved forward. The main sprocket drive motor 34M rotates the main sprocket 34 by a pitch in a direction to move the upper end of the main sprocket 34 forward.

  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 moves forward along with the base tape 21 while being moved 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, 5, 6, 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.

  6 and 8, the bracket portion 51 is provided with a claw portion 56 that protrudes and extends horizontally. The bracket portion 51 is swingable about the swing shaft 53 between an initial position (position shown in FIG. 6) 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, At the same time, the vehicle enters the travel path 41. 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 running path 41, the carrier tape 17 is removed 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. The carrier tape 17 cannot be pulled out from the travel path 41 unless the is removed, and the unintentional removal of the carrier tape 17 from the travel path 41 is prevented.

  4 and 6, a push-up member 61 is provided in the main body 31 and at a position below the feed sprocket 32. The push-up member 61 is movable in a guide groove 31G formed in the main body portion 31 in a shape extending obliquely forward and upward. The lifting member 61 is biased forward and obliquely upward by a spring 62. The upper surface of the push-up member 61 constitutes a part of the traveling path 41.

  The push-up member 61 can move up and down between a lower position where the upper surface coincides with the upper surface of the traveling path 41 and an upper position where the upper surface protrudes upward from the upper surface of the traveling path 41 by the thickness of the carrier tape 17. (Arrow L shown in FIG. 6). The upper surface of the push-up member 61 faces the feed sprocket 32, and the carrier tape 17 in the traveling path 41 is pushed up toward the outer peripheral teeth of the feed sprocket 32 by being biased obliquely forward and upward by the spring 62.

  4 and 6, a stopper member 71 and a standby tape detection sensor 72 are provided at a position slightly ahead of the feed sprocket 32 of the main body 31. The stopper member 71 has a front end portion pivotally supported by the main body portion 31, and a rear end portion side is swingable in the vertical direction. At the rear end of the stopper member 71, a protrusion 71T that protrudes downward and extends is formed. The up and down swinging motion of the stopper member 71 is interlocked with the up and down motion of the push-up member 61. When the push-up member 61 is located at the lower position, the stopper member 71 is located at the lower position and moves the protrusion 71T along the travel path. When the push-up member 61 is positioned at the upper position, the stopper member 71 is positioned at the upper position and retracts the protrusion 71T from the travel path 41.

  While the preceding carrier tape 17 (referred to as the preceding carrier tape 17A) is traveling in the traveling path 41, the following carrier tape 17 (referred to as the following carrier tape 17B) travels while contacting the upper surface of the preceding carrier tape 17A. When entering the path 41, the stopper member 71 causes the protrusion 71T to abut the leading portion of the subsequent carrier tape 17B to prevent further progression of the subsequent carrier tape 17B, and the subsequent carrier tape 17B is in a standby state. To. 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 72 detects the subsequent carrier tape 17B in contact with the stopper member 71 and in a standby state in this way.

  5 and 6, the guide moving mechanism 38 includes a guide side bevel gear 81, a swing motor 82, and a motor side bevel gear 83. The guide-side bevel gear 81 is fixed to the bracket portion 51 with its central axis coinciding with the central axis of the swing shaft 53. The swing motor 82 is attached to the main body 31, and the motor side bevel gear 83 is attached to the drive shaft of the swing motor 82. The motor side bevel gear 83 meshes with the guide side bevel gear 81, and when the swing motor 82 rotates the motor side bevel gear 83, the guide portion 37 swings around the swing shaft 53 accordingly.

  5 and 6, the cutting mechanism 39 includes a pressing member 91 and a cutter member 92. In FIG. 6, the pressing member 91 can be moved up and down by a pressing member lifting cylinder 91S, and the cutter member 92 can be moved up and down by a cutter member lifting cylinder 92S. Each of the pressing member 91 and the cutter member 92 has a shape extending upward, and the upper end portion of the cutter member 92 is a blade surface 92H. The pressing member 91 and the cutter member 92 are arranged side by side in the front-rear direction at a position directly below the swing shaft 53 of the wheel portion 52 provided in the guide portion 37.

  5 and 6, the pressing member 91 includes a cutter stopper 91 </ b> C that moves up and down integrally with the pressing member 91. The cutter stopper 91C is in contact with the cutter member 92 when the amount of the upper end portion of the cutter member 92 (that is, the blade surface 92H) protruding above the upper end portion of the pressing member 91 reaches the thickness of the carrier tape 17. Further upward movement of the cutter member 92 (relative upward movement with respect to the pressing member 91) is regulated.

  The control unit 40 cuts the scheduled cutting site when the predetermined scheduled cutting site for the carrier tape 17 is positioned immediately above the cutting mechanism 39. The scheduled cutting site is set at an arbitrary position between two adjacent component storage portions 23 on the carrier tape 17, but normally, the components PT are not wasted (all components PT are components). Therefore, the part to be cut is located behind the part PT (referred to as “rear end part”) located at the rear end of the row of parts PT accommodated in the carrier tape 17. Is set.

  In FIG. 6, a component detection sensor 93 is provided at a position behind the cutting mechanism 39 in the main body 31. The component detection sensor 93 emits inspection light from the opening 31H provided in the main body 31, and detects whether or not the component PT is stored in the component storage portion 23 of the carrier tape 17 passing above. . Since the component detection sensor 93 does not output the detection signal of the component PT to the control unit 40 after detecting the rear end component of the row of the components PT accommodated in the carrier tape 17, the rear end component of the carrier tape 17 is detected. It functions as a rear end part detecting means for detecting.

  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 37 </ b> K advances while being inserted into the feed hole 24 in a retaining pin 52 </ b> P provided in the wheel portion 52, enters the traveling path 41, and engages with the feed sprocket 32. At this time, the push-up member 61 is located at the upper position, and the stopper member 71 retracts the protrusion 71T from the travel path 41, so that the carrier tape 17 advances on the push-up member 61 without coming into contact with the protrusion 71T. Then, the feed sprocket 32 is rotated more than a predetermined rotation. 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 40 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 40 operates the swing motor 82. As a result, the motor side bevel gear 83 rotates, and the bracket portion 51 swings around the swing shaft 53 (arrow B1 shown in FIG. 9B) and is positioned at the upper position. The number of parts PT may be counted, and the swing motor 82 may be activated when a predetermined number is reached.

  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 (FIGS. 10 (c) and 11 (a). Arrow C2 shown in FIG. 10 (c)).

  When the carrier tape 17 falls through the tape passage 60, the control unit 40 operates the swing motor 82 at that timing to swing the bracket unit 51 in the reverse direction (arrow B2 shown in FIG. 11A). ), The guide part 37 is returned to the initial position. As a result, the insertion port 37K is opened, and the carrier tape 17 can be newly inserted from the guide portion 37.

  As described above, in the present embodiment, the control unit 40 moves the guide unit 37 relative to the main body unit 31, and the portion of the carrier tape 17 engaged with the main sprocket 34 is guided by the guide unit 37. The insertion port 37K is opened by dropping from the guide portion 37.

  When the guide unit 37 returns 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 traveling path 41 and advances through the traveling path 41, and engages with the outer peripheral teeth of the feed sprocket 32. At this time, the push-up member 61 is lowered by the thickness of the subsequent carrier tape 17B in addition to the thickness of the preceding carrier tape 17A, so that the stopper member 71 swings downward, and the protrusion 71T is the top of the subsequent carrier tape 17B. Abuts against the part. For this reason, the subsequent carrier tape 17B is prevented from proceeding further and 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 71, the push-up member 61 rises by the thickness of the preceding carrier tape 17A, so that the stopper member 71 swings upward. The movement of the subsequent carrier tape 17B is released. When the standby tape detection sensor 72 detects that the standby state of the subsequent carrier tape 17B has been released, the control unit 40 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.

  When the carrier tape 17 in the traveling path 41 is engaged with the main sprocket 34 and a portion of the carrier tape 17 guided by the guide portion 37 is dropped, the components in each component storage portion 23 by the component detection sensor 93 are detected. The presence or absence of PT can be detected. Based on the detection information from the running tape detection sensor 45 and the detection information from the component detection sensor 93, the control unit 40 determines that the position of the planned cutting portion of the carrier tape 17 (preceding carrier tape 17 </ b> A) is directly above the cutter member 92. When the reached state is detected, the carrier tape 17 is cut by the cutting mechanism 39.

  The control unit 40 executes the cutting of the carrier tape 17 when the traveling of the carrier tape 17 (the preceding carrier tape 17A) is temporarily stopped by the pitch feed by the main sprocket 34. When the control unit 40 cuts the carrier tape 17 by the cutting mechanism 39, first, the pressing member lifting cylinder 91S is operated to push up the pressing member 91 from below (FIG. 12 (a) → FIG. 12 (b)). The carrier tape 17 is pressed against the wheel portion 52 from below through the tape passage 60 of the bracket portion 51. Then, by operating the cutter member elevating cylinder 92S to raise the cutter member 92 (FIG. 12B → FIG. 13A), the cutter member 92 is applied to the carrier tape 17 pressed against the wheel portion 52 by the pressing member 91. The blade surface 92H is pressed from below to cut the carrier tape 17 (FIG. 13A).

  When the carrier tape 17 is cut, the control unit 40 returns the pressing member 91 and the cutter member 92 to their original positions (FIG. 13B). Of the cut carrier tape 17, the portion on the end side of the portion to be cut (the portion indicated by reference numeral 17C in FIGS. 13A and 13B) falls due to its own weight. On the other hand, in the carrier tape 17, the leading portion (the portion that is pitch-fed by the main sprocket 34) continues to feed the pitch with the cut portion (original cut planned portion) as a new end portion.

  Here, as described above, since the pressing member 91 includes the cutter stopper 91C that moves up and down integrally with the pressing member 91, the blade surface 92H of the cutter member 92 is independent of the vertical position of the pressing member 91. Does not protrude above the pressing member 91 beyond the thickness of the carrier tape 17. For this reason, even if the carrier tape 17 is cut, the wheel portion 52 is not damaged by the cutter member 92.

  Further, after the carrier tape 17 (preceding carrier tape 17A) is dropped from the guide portion 37, when the preceding carrier tape 17A is cut in a state where the subsequent carrier tape 17B is inserted in the guide portion 37 (FIG. 14 ( a)) The cutting mechanism 39 operates in the same procedure as described above while the subsequent carrier tape 17B is inserted into the insertion port 37K. That is, the control unit 40 operates the pressing member elevating cylinder 91S to push up the pressing member 91 from below (FIG. 14 (a) → FIG. 14 (b), and presses the preceding carrier tape 17A against the wheel unit 52 from below. The pressing member 91 presses the preceding carrier tape 17A together with the subsequent carrier tape 17B against the wheel portion 52.

  When the preceding carrier tape 17A is pressed against the wheel portion 52, the control unit 40 operates the cutter member lifting cylinder 92S to raise the cutter member 92 (FIG. 14 (b) → FIG. 15 (a)) and presses against the wheel portion 52. The leading carrier tape 17A is pressed against the leading carrier tape 17A to cut the leading carrier tape 17A (FIG. 15B). At this time, the blade surface 92H of the cutter member 92 does not protrude upward beyond the thickness of the carrier tape 17 relative to the pressing member 91. Therefore, even if the preceding carrier tape 17A is cut, the subsequent carrier tape 17B is It is not cut by the member 92. When the preceding carrier tape 17A is cut, the control unit 40 returns the pressing member 91 and the cutter member 92 to their original positions (FIG. 15B).

  As described above, in the tape feeder 16 according to the present embodiment, the control unit 40 controls the guide unit moving mechanism 38 to move the guide unit 37, and guides the carrier tape 17 engaged with the main sprocket 34. Since the portion guided by the portion 37 is dropped from the guide portion 37 to open the insertion port 37K, the subsequent carrier tape 17B can be inserted from the insertion port 37K. Thus, the operator OP does not need to perform the work of dropping the preceding carrier tape 17A from the guide portion 37 for inserting the succeeding carrier tape 17B, and the burden of monitoring the status of the carrier tape 17 is reduced. In addition, since the carrier tape 17 is automatically dropped from the guide portion 37 in this way, the operator OP visually recognizes the state where the carrier tape 17 has dropped from the guide portion 37, so that the tape feeder 16 is moved to the subsequent carrier tape. Since it can be confirmed that 17B can be inserted, there is no possibility of inserting the subsequent carrier tape 17B at an incorrect time.

  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.

  Provided are a tape feeder and a mounting substrate manufacturing method capable of reducing the burden of monitoring the state of a carrier tape by an operator.
