Description

[Technical Field]

[0001] The present disclosure relates to a component supplying device that supplies components to a component mounting device. [Background technology]

[0002] Conventionally, a tape feeder can continuously supply a succeeding carrier tape (following tape) to a component pick-up position after a preceding carrier tape (leading tape) that contains components. is known.

[0003] For example, the tape feeder described in Patent Document 1 includes a tape holding unit on the upstream side of the tape running path that holds the following tape whose leading end is inserted into a tape inlet. The tape holding unit has a tape holding part that can be displaced vertically by an operator, and is configured so that the following tape that it holds can fall downward by displacing the tape holding part vertically.

[0004] In this tape feeder, when the leading tape is discharged and the trailing tape becomes the leading tape and begins supplying components, the operator operates the tape holding unit to drop the leading tape from the tape holding unit and correct its position. This makes it possible to replenish the trailing tape. After that, the new trailing tape is held by the tape holding unit and its leading edge is inserted into the tape inlet, completing the carrier tape replenishment work.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2019-117820 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in conventional tape feeders, the operation of discharging the trailing tape downward is performed manually by an operator, which can lead to the operator forgetting to discharge the tape. In this case, the component mounting device must stop mounting operations while components cannot be replenished, which can reduce productivity. Furthermore, because switching from the leading tape to the trailing tape is performed manually by an operator, it is difficult to automate or reduce the labor required for supplying components to the component mounting device.

[0007] Therefore, an object of the present disclosure is to solve the above-mentioned conventional problems and to provide a component supply device that can improve productivity and automate or reduce the labor required to supply components to a component mounting device. [Means for solving the problem]

[0008] The component supply device of the present disclosure has a first transport path into which a carrier tape is inserted and a second transport path located below the first transport path, each located upstream, and is equipped with a tape transport path where the first transport path and the second transport path converge to guide the carrier tape to run in a downstream direction, a first tape transport unit that sequentially transports the carrier tape of the tape transport path downstream of the position where the first transport path and the second transport path converge to a component removal position of the tape transport path, a tape holding unit that holds the carrier tape in at least a portion of the first transport path, a second tape transport unit that transports the carrier tape held in the tape holding unit in the downstream direction of the tape transport path, a tape retention release mechanism that drops the carrier tape held in the tape holding unit to the second transport path, and a control unit that drives the tape retention release mechanism at a timing after the carrier tape transported by the second tape transport unit is handed over to the first tape transport unit. [Effects of the Invention]

[0009] According to the present disclosure, it is possible to provide a component supplying device that can improve productivity and automate or reduce the labor required to supply components to a component mounting device. [Brief explanation of the drawings]

[0019] Hereinafter, exemplary embodiments of a component mounting apparatus according to the present disclosure will be described with reference to the accompanying drawings. The present disclosure is not limited to the specific configurations of the following embodiments, and configurations based on similar technical concepts are also included in the present disclosure.

[0020] (Embodiment) The configuration of a component mounting apparatus 1 according to an embodiment of the present disclosure will be described with reference to Fig. 1. In Fig. 1, two axial directions perpendicular to each other in a horizontal plane are shown: the X direction (the direction perpendicular to the paper surface in Fig. 1) in which the board is transported; and the Y direction (the left-right direction in Fig. 1) perpendicular to the board transport direction. Also, the Z direction (the up-down direction in Fig. 1) is shown as the height direction perpendicular to the horizontal plane.

[0021] The configuration of component mounting apparatus 1 will be described with reference to Figure 1. Component mounting apparatus 1 manufactures mounted boards, each having components mounted on it. A board transport mechanism 2 provided on the upper surface of base 1a transports, positions, and holds board 3 in the X direction. A mounting head 4 is installed above board transport mechanism 2 and moves in horizontal directions (X and Y directions) by a head movement mechanism (not shown). A carriage 5 is connected to base 1a on the side of board transport mechanism 2 and has multiple tape feeders 6 attached to the top of the carriage 5, lined up in the X direction.

[0022] A reel holder 9 is provided on the front side of the carriage 5 and below the tape feeder 6. The reel holder 9 rotatably supports a reel 8 around which a carrier tape 7 is wound, the carrier tape 7 storing components to be supplied to the component mounting device 1. The tape feeder 6 transports the carrier tape 7 stored on the reel 8 in the tape feed direction to supply the components to a component pick-up position P1 where the mounting head 4 picks up the components. An identifier 8a is attached to the reel 8 to identify the components stored on the carrier tape 7. The identifier 8a is, for example, a two-dimensional barcode or an RFID tag.

[0023] The component mounting apparatus 1 includes a mounting control unit 10 that controls the board transport mechanism 2, the mounting head 4, and the head movement mechanism. The mounting control unit 10 sends a component supply command to the tape feeder 6 and controls the mounting head 4 and the head movement mechanism to perform a component mounting operation in which the mounting head 4 retrieves the components supplied by the tape feeder 6 to the component removal position and transfers and mounts them at the mounting point on the board 3 held by the board transport mechanism 2. In this way, the tape feeder 6 is a component supply device that supplies components stored on a carrier tape 7 to the component mounting apparatus 1. The components stored on the carrier tape 7 are, for example, chip-type electronic components. A freely closable main body cover 11 is installed above the cart 5 to prevent workers from touching the moving mechanisms, such as the mounting head 4, during operation.

[0024] The component mounting apparatus 1 further includes a reader device 15 that reads information from the identifier 8a. The reader device 15 is, for example, a two-dimensional barcode reader or an RFID reader. The information from the identifier 8a read by the reader device 15 is sent to the mounting control unit 10. The mounting control unit 10 includes a collating unit 10a and a storage unit 10b. The mounting control unit 10 is configured with, for example, an arithmetic unit such as a processor or FPGA, and a memory or SSD.

[0025] Memory unit 10b stores information about parts to be replenished to tape feeder 6. Collation unit 10a collates the information about identifier 8a read by reader device 15 with the information about the parts to be replenished stored in memory unit 10b. If collation unit 10a determines that the information about identifier 8a matches the information about the parts to be replenished, it transmits a signal indicating a match to feeder control unit 28 as a result of the collation. If collation unit 10a determines that the information about identifier 8a does not match the information about the parts to be replenished, it transmits a signal indicating a mismatch to feeder control unit 28 as a result of the collation.

[0026] In Figure 1, a collection box 12 is installed below the carriage 5 to collect empty carrier tape 7 that has had components removed by the mounting head 4 and is discharged from the rear of the tape feeder 6. A discharge chute 13 is installed at the rear of the carriage 5 to guide the empty carrier tape 7 discharged from the tape feeder 6 to the collection box 12. A cutting unit 14 is installed in the discharge chute 13 to cut the empty carrier tape 7 to a predetermined length. The empty carrier tape 7 discharged from the tape feeder 6 is cut by the cutting unit 14 and collected in the collection box 12.

[0027] <Tape feeder> Next, the configuration of the tape feeder 6 will be described with reference to Figures 2 and 3. Figure 2 is a schematic diagram of the tape feeder 6 according to the embodiment. Figure 3 is a partially enlarged view of the tape feeder 6.

[0028] The tape feeder 6 includes a tape transport path 20, a first tape transport unit 21, a second tape transport unit 23, a tape holding unit 26, and a tape hold release mechanism 34. The tape feeder 6 also includes an insertion opening 20a through which the carrier tape 7 is inserted into the tape transport path 20, and an ejection opening 20b through which the carrier tape 7 is ejected from the tape transport path 20.

[0029] The tape transport path 20 guides the carrier tape 7, which has been pulled out from the reel 8 and inserted into the tape feeder 6 through the insertion opening 20a, to the component removal position P1 inside the tape feeder 6, and further to the discharge opening 20b.

[0030] The insertion opening 20a opens on the upstream side of the tape feed direction of the tape feeder 6 (the left side in FIG. 2). The discharge opening 20b opens on the downstream side of the tape feed direction (the right side in FIG. 2). The tape transport path 20 is connected from the insertion opening 20a to the discharge opening 20b. The mounting head 4 takes out a component at a component take-out position P1 provided midway along the tape transport path 20.

[0031] In the process of continuously performing component mounting work, a plurality of carrier tapes 7, each of which is stored on one reel 8 and constitutes a unit lot, are sequentially inserted through the insertion port 20a and supplied to the tape feeder 6. In the following description, as necessary, of the two carrier tapes 7 introduced through the insertion port 20a and fed along the tape feed path 20, the carrier tape 7 fed first will be referred to as the first tape 7p, and the carrier tape 7 fed next to the first tape 7p will be referred to as the second tape 7s (see FIG. 3). The tape feed path 20 has a first feed path 20c into which the carrier tape 7 is inserted on the upstream side, a second feed path 20d located below the first feed path 20c, and a third feed path 20e extending from a junction P2 of the second feed path 20d and the first feed path 20c to the discharge port 20b.

[0032] The first tape transport unit 21 transports the carrier tape 7 to a component removal position P1 on the downstream side of the tape transport path 20. The first tape transport unit 21 includes a first sprocket 21a that engages with the carrier tape 7 and a first motor 21b that rotates and drives the first sprocket 21a. A tape cover 22 is attached above the first tape transport unit 21 to press the carrier tape 7 from above and to expose the components stored on the carrier tape 7. An opening is formed in the tape cover 22 at a position corresponding to the component removal position P1. When the first sprocket 21a moves the carrier tape 7 along the underside of the tape cover 22, the components are exposed by the peeling blade, and the exposed components are transported to an opening formed downstream, i.e., the component removal position P1. The method for exposing the components stored in the carrier tape 7 may be a method (full peeling method) in which a pair of rollers (not shown) is arranged downstream of the component removal position P1 on the tape transport path 20, and these rollers peel off the top tape sealing the components in the carrier tape 7. In the case of the full peeling method, it is not necessary to provide a peeling blade on the tape cover 22.

[0033] The second tape transport unit 23 feeds the carrier tape 7 inserted into the first transport path 20c from the insertion port 20a to the first tape transport unit 21. The second tape transport unit 23 is disposed on the upstream side of the tape transport path 20. The second tape transport unit 23 includes, for example, a second motor 23a, a first gear 23b, a second gear 23c, a third gear 23d, a fourth gear 23e, a fifth gear 23f, and a second sprocket 23g.

[0034] The output gear 23aa of the second motor 23a engages with the first gear 23b. The second gear 23c is rotatably disposed coaxially with the first gear 23b and engages with the third gear 23d. The third gear 23d engages with the fourth gear 23e, and the fourth gear 23e engages with the fifth gear 23f. The fifth gear 23f is rotatably fixed to the second sprocket 23g, which engages with the carrier tape 7. Therefore, the rotational driving force of the second motor 23a is transmitted from the first gear 23b to the second sprocket 23g via the fifth gear 23f.

[0035] The tape transport path 20 has a first transport path 20c and a second transport path 20d on the upstream side. The first transport path 20c and the second transport path 20d merge at position P2. The carrier tape 7 supplied to the tape feeder 6 is first transported downstream of the tape transport path 20 along the first transport path 20c by the second tape transport unit 23. When the carrier tape 7 is eventually transported to the first tape transport unit 21, the carrier tape 7 is moved from the first transport path 20c to the second transport path 20d as the preceding first tape 7p. As a result, the first tape 7p is transported downstream of the tape transport path 20 from the second transport path 20d through the third transport path 20e, allowing the next second tape 7s to be inserted into the first transport path 20c.

[0036] The tape feeder 6 includes a tape stopper portion 24, a shutter unit 27, and a locking portion 45, which are each disposed below the second tape transport portion 23. The tape feeder 6 also includes a first sensor Sa1, a second sensor Sa2, and a third sensor Sa3.

[0037] The first sensor Sa1 detects that the carrier tape 7 inserted into the tape feeder 6 has reached a predetermined position on the third conveying path 20e downstream of the position P2 where the second conveying path 20d and the first conveying path 20c join.

[0038] The second sensor Sa2 detects that the carrier tape 7 traveling on the tape transport path 20 has reached just before the component take-out position P1. Therefore, the second sensor Sa2 is disposed downstream of the tape transport path 20 from the first sensor Sa1 and upstream of the tape transport path 20 from the third sensor Sa3.

[0039] The third sensor Sa3 detects that the carrier tape 7 traveling on the tape transport path 20 has reached the component take-out position P1. The third sensor Sa3 is disposed, for example, downstream of the second sensor Sa2 and the first sprocket 21a of the first tape transport unit. The first sensor Sa1 to the third sensor Sa3 are each optical sensors that detect the presence or absence of the carrier tape 7, and are, for example, color sensors or photo sensors.

[0040] The tape holding unit 26 supports the carrier tape 7 in at least a portion of the first transport path 20c and maintains the orientation of the carrier tape 7 as it is transported. See Figure 4. The tape holding unit 26 includes a first support unit 30, a second support unit 31, a plate-like member 32, and a movable member 33. For convenience, in the following description, one side will be referred to as the left and the other side will be referred to as the right, facing the downstream direction in which the carrier tape 7 is transported in the tape feeder 6, as shown in Figure 4.

[0041] The first support portion 30 supports one widthwise side of the carrier tape 7 from below. The first support portion 30 is formed on the right side surface of the plate-like member 32. The second support portion 31 supports the other widthwise side of the carrier tape 7 from below.

[0042] The plate-shaped member 32 extends in the tape feed direction and the vertical direction (Z direction). The inner surface (right surface) of the plate-shaped member 32 is a guide surface that guides the left surface of the carrier tape 7. The plate-shaped member 32 is fixed to the side wall of the tape feeder 6.

[0043] The movable member 33 has a plate-like shape and is connected so as to be able to swing up and down around the rotation shaft 26a. The inner surface of the movable member 33 is a guide surface that guides the right side surface of the carrier tape .

[0044] A handle 38 equipped with a lever that an operator can operate with his / her fingers is formed on the top of the movable member 33. When the operator lifts the handle 38 upward, the upstream side of the movable member 33 can be lifted upward (see FIG. 9). In this way, the movable member 33 can be displaced in the up and down direction relative to the plate-like member 32 to which it is fixed (see FIG. 11).

[0045] 4, a rotating shaft 39 having a rotation center parallel to the width direction of the carrier tape 7 is attached to the movable member 33. A second sprocket 23g is rotatably attached to the rotating shaft 39 via a one-way clutch 40. A plurality of pins 41a are provided on the left side of the outer circumferential surface of the second sprocket 23g (i.e., on the side closer to the plate-like member 32). When the movable member 33 is in its initial position, the pins 41a of the second sprocket 23g engage with feed holes 7h formed in the carrier tape 7, the underside of which is supported by the first support portion 30 and the second support portion 31.

[0046] First support part 30 supports from below the side of carrier tape 7 on which feed holes 7h are formed. Second sprocket 23g, which is attached to horizontal rotating shaft 39 via one-way clutch 40, constitutes a locking part that engages with feed holes 7h of carrier tape 7 to lock carrier tape 7 to first support part 30.

[0047] One-way clutch 40 allows rotation of second sprocket 23g when carrier tape 7 engaged with second sprocket 23g moves on tape holding portion 26 toward insertion opening 20a, but does not allow rotation in the opposite direction. This prevents carrier tape 7 from falling off tape feeder 6. In this way, second sprocket 23g is attached to movable member 33 via one-way clutch 40 to rotation shaft 39, whose rotation axis is horizontal.

[0048] A protrusion 42 that protrudes inward from the plate-shaped member 32 is formed on the inner surface of the plate-shaped member 32 at a position above the first support portion 30. A taper 42a is formed at the lower end of the protrusion 42, having a slope that approaches the inner surface of the plate-shaped member 32 downward (a slope that moves away from the right side surface of the plate-shaped member 32 upward). In other words, the horizontal width of the lower end of the protrusion 42 narrows as it extends downward.

[0049] 5, the downstream end of the second support part 31 is located upstream of the downstream end of the first support part 30. Also, on the downstream side of the second support part 31, a notch part 31a is formed, the notch part 31a having a slope whose side surface approaches the inner surface of the movable member 33 as it approaches the downstream side. That is, one end of the second support part 31 on the insertion opening 20a side (downstream side) becomes narrower in the horizontal direction as it approaches the insertion opening 20a side.

[0050] Next, the configuration of the tape holding release mechanism 34 will be described with reference to Figures 6 to 10. Figures 6 to 10 are side views showing the configuration of the second tape transport section 23 of the tape feeder 6 and the tape holding release mechanism 34.

[0051] The tape retention release mechanism 34 drops the carrier tape 7 held by the tape holding unit 26 on the first transport path 20c onto the second transport path 20d. The tape retention release mechanism 34 is operated using the power of the second motor 23a of the second tape transport unit 23. The tape retention release mechanism 34 includes a ratchet mechanism 35 that rotates by the driving force of the second motor 23a, and a lever 36 that is swung by the ratchet mechanism 35.

[0052] The ratchet mechanism 35 is made up of a ratchet gear 35a and a ratchet pawl 35b. The ratchet gear 35a is rotatably attached to the third gear 23d coaxially with the third gear 23d. Therefore, the ratchet gear 35a rotates together with the third gear.

[0053] Lever 36 is, for example, L-shaped, with ratchet pawl 35b formed on one end and connected at the other end to the downstream end of movable member 33 of tape holding unit 26. Rotation shaft 36a is provided in the center of lever 36, and lever 36 is attached to tape feeder 6 via second motor 23a so as to be swingable around rotation shaft 36a.

[0054] 6 and 7, when the second motor 23a rotates forward, the second motor 23a and the ratchet gear 35a rotate counterclockwise. In this case, the ratchet gear 35a acts to lift the ratchet pawl 35b of the lever 36, so the ratchet pawl 35b continues to rotate freely without engaging with the ratchet gear 35a.

[0055] 8, when the second motor 23a rotates in the reverse direction, the second motor 23a and the ratchet gear 35a rotate clockwise. In this case, the ratchet gear 35a acts to press down the ratchet pawl 35b of the lever 36, so that the ratchet pawl 35b engages with the ratchet gear 35a and the lever 36 starts to rotate counterclockwise.

[0056] When the second motor 23a further rotates in the reverse direction, as shown in Figure 9, the ratchet gear 35a presses down the ratchet pawl 35b of the lever 36, causing the lever 36 to rotate counterclockwise. This causes the lever 36 to press down the downstream end of the movable member 33 of the tape holding unit 26. As a result, the movable member 33 rotates clockwise around the rotation shaft 26a, and the second support unit 31 moves upward to the release position P3.

[0057] Furthermore, as the second motor 23a continues to rotate in the reverse direction, as shown in Figure 10, the ratchet gear 35a continues to act to press down the ratchet pawl 35b of the lever 36, so the ratchet pawl 35b of the lever 36 does not engage with the ratchet gear 35a. Therefore, the state in which the lever 36 presses down the downstream end of the movable member 33 of the tape holding part 26 remains, and the second support part 31 of the tape holding part 26 remains in the upper release position P3.

[0058] Next, when the second motor 23a rotates forward, the ratchet gear 35a acts to lift the ratchet pawl 35b of the lever 36, so that the ratchet gear 35a engages with the ratchet pawl 35b of the lever 36 and the lever rotates clockwise. As a result, the lever 36 lifts the downstream end of the movable member 33 of the tape holding part 26 upward, and the second support part 31 moves to its original position, the tape holding position.

[0059] Next, referring to FIG. 11, the function of releasing the carrier tape 7 from the tape holding unit 26 on the first feed path 20c will be described. As shown in FIG. 11(a), the carrier tape 7 is held by the tape holding unit 26 with the movable member 33 in its initial position and the second support member 31 at the same height as the first support member 30. When releasing the carrier tape 7 on the first feed path 20c from the tape holding unit 26, the feeder control unit 28 reverses the rotation of the second motor 23a of the second tape feed unit 23. This causes the movable member 33 to rise together with the second support member 31 and the second sprocket 23g. The movable member 33 can also be raised by manually holding the handle 38 and lifting it upward.

[0060] 11(b), as the movable member 33 rises, the carrier tape 7 moves upward while the lower surface of the right side is supported by the second support portion 31, and the upper surface of the left side of the carrier tape 7 abuts against the protrusion 42. As the movable member 33 rises further, the pin 41a of the second sprocket 23g disengages from the feed hole 7h of the carrier tape 7. As shown in FIG. 11(c), as the carrier tape 7 rises further together with the movable member 33, the carrier tape 7 is pushed by the taper 42a of the protrusion 42 and displaced to a position (to the right) where it does not overlap with the first support portion 30, and twisted counterclockwise.

[0061] 11(d), as the movable member 33 rises further, the twist in the carrier tape 7 increases, and eventually the right end of the carrier tape 7 slips off the second support part 31. At this time, the right end of the carrier tape 7 slips off reliably, starting from the notch 31a on the downstream side of the second support part 31. In addition, because the left end of the carrier tape 7 has been displaced to the right by the protrusion 42, the carrier tape 7 falls downward without getting caught on the first support part 30 (shown by the dotted line in the figure).

[0062] The carrier tape 7 released from the tape holding unit 26 moves as a first tape 7p to a second transport path 20d formed below the first transport path 20c (see FIG. 3). The carrier tape 7 is released from the tape holding unit 26, for example, before the carrier tape 7 is inserted into the tape feeder 6 and a component is removed from the component removal position P1. Once the carrier tape 7 (first tape 7p) has been released from the tape holding unit 26, the next carrier tape 7 (second tape 7s) can be inserted into the tape holding unit 26 at any time.

[0063] <Shutter unit> Next, the shutter unit 27 will be described with reference to Figures 14 and 15. Figure 14 is a partially enlarged view of the periphery of the shutter unit. Figure 15 is a side view showing the configuration of the shutter unit 27 and the locking portion 45.

[0064] The shutter unit 27 prevents the carrier tape 7 from advancing until the verification of the components on the carrier tape 7 inserted into the first transport path 20c is completed. The shutter unit 27 includes a shutter 27a, a pin 27b, a coil spring 27c, and a fourth sensor Sa4.

[0065] The shutter 27a comes into contact with the carrier tape 7 to stop the advancement of the carrier tape 7. The shutter 27a includes a shutter main body 27e and a plate-like member 27f.

[0066] The shutter body 27e includes an inclined portion 27ea with which the carrier tape 7 comes into contact, an elongated hole 27eb extending in the vertical direction, and a stepped portion 27ec that fits into the locking portion 45. A pin 27b is inserted into the elongated hole 27eb, and the shutter 27a can be displaced in the vertical direction along the elongated hole 27eb.

[0067] The plate-like member 27f extends upward from the shutter main body 27e. The fourth sensor Sa4 detects whether the shutter 27a is located at tape stop position P4, where the advancement of the carrier tape 7 is stopped, or at retracted position P5 above tape stop position P4. The fourth sensor Sa4 is, for example, an optical sensor. When the shutter 27a is located at tape stop position P4, the shutter 27a is lowered to the first transport path 20c, and therefore the fourth sensor Sa4 cannot detect the plate-like member 27f. When the shutter 27a is located at retracted position P5, the shutter 27a is raised upward from the first transport path 20c, and therefore the fourth sensor Sa4 detects the plate-like member 27f.

[0068] The coil spring 27c biases the shutter body 27e so as to press the shutter 27a downward, i.e., so that the lower end of the shutter body 27e comes into contact with the first conveying path 20c. When the carrier tape 7 is conveyed downstream by the second tape conveying section 23, the carrier tape 7 lifts the shutter 27a against the spring force of the coil spring 27c and advances.

[0069] The locking unit 45 locks the displacement of the shutter 27a under the control of the feeder control unit 28. The locking unit 45 includes a solenoid 46, a lever 47, and a coil spring 48.

[0070] The solenoid 46 attracts the lever 47, which prevents the shutter 27a from moving, downstream so that the shutter 27a can move from the retracted position P5 to the tape stop position P4. The solenoid 46 includes a plunger 46a and a disk-shaped plate member 46b fixed to the tip of the plunger 46a. The plate member 46b of the solenoid 46 engages with the downstream end 47b of the lever 47. When the solenoid 46 receives a suction command from the feeder control unit 28, it displaces the plunger 46a to the suction position and displaces the lever 47 downstream. When the suction command from the feeder control unit 28 is removed, the solenoid 46 displaces the plunger 46a to its original release position.

[0071] The lever 47 is biased upstream, i.e., toward the shutter 27a, by a coil spring 48. When the plunger 46a of the solenoid 46 is in the released state, the upstream end 47a of the lever 47 is engaged with a stepped portion 27ec of the shutter main body 27e, thereby preventing the shutter 27a from rising to the retracted position P5 and locking the movement of the shutter 27a.

[0072] If the component matching performed by the placement control unit 10 matches the component that should be supplied, the feeder control unit 28 sends a suction command to the solenoid 46. As a result, as shown in Fig. 14, the solenoid 46 attracts the plunger 46a, displacing the lever 47 downstream. As a result, the upstream end 47a of the lever 47 disengages from the stepped portion 27ec of the shutter main body 27e, unlocking the shutter 27a.

[0073] Even when the shutter 27a is unlocked, the shutter 27a is still biased downward by the coil spring 27c, but the feeder control unit 28 stops issuing the suction command to the solenoid 46 and then sends a command to transport the tape to the second tape transport unit 23, so that the carrier tape 7 is transported downstream. As a result, the leading end of the carrier tape 7 pushes up the inclined portion of the shutter main body 27e against the spring force of the coil spring 27c.

[0074] When the leading end of the carrier tape 7 pushes the shutter body 27e upward, the plate-like member 27f of the shutter 27a is also displaced upward, and the fourth sensor Sa4g detects the plate-like member 27f, thereby detecting that the carrier tape 7 has passed under the shutter 27a, i.e., that the carrier tape 7 has been transported from the first transport path 20c toward the third transport path 20e.

[0075] If the component matching by the placement control unit 10 indicates that the component does not match the component that should be supplied, the feeder control unit 28 notifies the worker that the set reel 8 is incorrect, for example, via the operation display panel 29. When the worker recognizes that the reel 8 is incorrect, he or she lifts the handle 38 of the tape holding unit 26 and removes the incorrectly inserted carrier tape 7 from the first transport path 20c.

[0076] <Tape stopper part> 16 to 18, the configuration of the tape stopper portion 24 will be described. When the first tape 7p is being transported along the second transport path 20d and the third transport path 20e, the tape stopper portion 24 stops the second tape 7s inserted into the first transport path 20c from advancing into the third transport path 20e.

[0077] The tape stopper portion 24 includes a stopper 24a, a lever 24b, and a fifth sensor Sa5.

[0078] Stopper 24a is, for example, a plate-shaped member that can be displaced between stop position P6 (see FIG. 17), where the advancement of second tape 7s is stopped, and stopper release position P7 (see FIG. 18), where the advancement of second tape 7s is released. Stopper 24a includes contact portion 24aa, tip portion 24ab, and fulcrum 24ac. When stopper 24a is at stop position P6, which is a predetermined position on first transport path 20c, contact portion 24aa comes into contact with the tip of second tape 7s, preventing second tape 7s from moving downstream along first transport path 20c.

[0079] The tip portion 24ab is a downstream portion of the stopper 24a, and is a transmitted portion that receives power from the lever 24b for displacement from the stop position P6 to the stopper release position P7.

[0080] The fulcrum 24ac is a fulcrum that serves as a rotation center for displacing the stopper 24a by rotation to the stop position P6 and the stopper release position P7. The fulcrum 24ac is located above the first conveying path 20c and upstream of the contact portion 24aa.

[0081] Lever 24b functions as a drive unit that moves stopper 24a between stop position P6 and stopper release position P7. Lever 24b itself is a link, and includes tape pressing portion 24ba, tip portion 24bb, claw portion 24bc, and fulcrum 24bd.

[0082] The tape pressing portion 24ba presses down the first tape 7p transported along the third transport path 20e from above. The coil spring 24c is biased so that the tape pressing portion 24ba pushes the first tape 7p downward. As the first tape 7p advances downstream, it lifts the tape pressing portion 24ba against the spring force of the coil spring 24c.

[0083] When the first tape 7p is lifting the tape presser 24ba, the fifth sensor Sa5 detects the claw 24bc extending upward from the top of the lever 24b. In this state, the upstream tip 24bb of the lever 24b is lowered, and the tip 24bb supports the weight of the tip 24ab of the stopper 24a.

[0084] As shown in FIG. 18, when the first tape 7p is completely transported downstream, the spring force of the coil spring 24c causes the tape presser 24ba to rotate clockwise and contact the third transport path 20e. This causes the lever 24b to rotate clockwise around the fulcrum 24bd, and the tip 24bb of the lever 24b rotates the tip 24ab of the stopper 24a counterclockwise. The tip 24bb functions as a power transmission unit that transmits rotational power to the tip 24ab of the stopper 24a. As a result, the stopper 24a rotates from the stop position P6 to the stopper release position P7, and the abutment portion 24aa is released from contact with the second tape 7s. At this time, the direction in which the abutment portion 24aa is released from the stop position P6 to the stopper release position P7 is the direction in which the second tape 7s advances. In other words, the abutment portion 24aa rotates in a direction away from the tip of the second tape 7s from the stop position P6 to the stopper release position P7, thereby preventing the abutment portion 24aa from digging into the tip of the second tape 7s and preventing the second tape 7s from getting stuck when the stopper 24a is released.

[0085] Furthermore, due to the rotation of lever 24b, the detection signal from fifth sensor Sa5 is no longer sent to feeder control unit 28. When feeder control unit 28 no longer receives a detection signal from fifth sensor Sa5, it recognizes that all of first tape 7p has been transported downstream and stopper 24a is located at stopper release position P7.

[0086] Next, feeder control unit 28 drives second tape transport unit 23 to transport second tape 7s downstream to transport second tape 7s to third transport path 20e. In this way, second tape 7s can be transported continuously following first tape 7p.

[0087] Next, the configuration of the control system of the tape feeder 6 will be described with reference to FIG. 19. The feeder control unit 28 of the tape feeder 6 includes a computing device configured with semiconductor elements such as a processor or FPGA, a storage device configured with a hard disk (HDD), memory, or SSD, and a communication unit 28a. The functions of the feeder control unit 28 may be implemented solely by hardware or by a combination of hardware and software. The feeder control unit 28 may implement predetermined functions by reading data and programs stored in the storage device and performing various arithmetic operations. The communication unit 28a is a communication interface that transmits and receives signals and data to and from the mounting control unit 10 of the component mounting device 1. Based on the detection results of the first sensor Sa1, the second sensor Sa2, and the third sensor Sa3, the feeder control unit 28 controls the first motor 21b and the second motor 23a to carry out the tape feeding operation of the carrier tape 7 and the tape release operation of the tape holding release mechanism 34 according to a predetermined control pattern.

[0088] Furthermore, the feeder control unit 28 controls the driving of the solenoid 46 based on the result of checking the identifier 8a of the reel 8 from the mounting control unit 10. Furthermore, upon receiving a detection signal from the fourth sensor Sa4, the feeder control unit 28 recognizes that the shutter 27a has been opened and the second tape 7s is being transported below the shutter 27a along the first transport path 20c.

[0089] Furthermore, when the feeder control section 28 is no longer able to receive a detection signal from the fifth sensor Sa5, it recognizes that the first tape 7p has been completely transported downstream from the second transport path 20d.

[0090] Next, the tape feeding operation in the tape feeder 6 will be described with reference to Figures 2 and 20. Figure 20 is a flowchart showing the flow of tape supply by the tape feeder 6.

[0091] In step S1, with the carrier tape 7 not yet supplied to the tape feeder 6, the worker inserts the carrier tape 7 into the first transport path 20c through the insertion opening 20a.

[0092] In parallel with step S1, the collating unit 10a of the mounting control unit 10 collates the identifier 8a of the reel 8 read from the reader device 15 with the component information stored in the memory unit 10b to determine whether the component on the carrier tape 7 inserted into the first transport path 20c is the correct component. The mounting control unit 10 transmits the collation result by the collating unit 10a to the feeder control unit 28.

[0093] In step S2, when feeder control unit 28 receives from mounting control unit 10 a comparison result (a signal indicating a match) indicating that the component on carrier tape 7 is the correct component, feeder control unit 28 drives solenoid 46 to unlock lock unit 45. Once the lock is released, the worker further inserts carrier tape 7 into tape transport path 20 via first transport path 20c, and when first sensor Sa1 detects the leading end of carrier tape 7, it transmits a detection signal to feeder control unit 28. Furthermore, when feeder control unit 28 receives from mounting control unit 10 a comparison result (a signal indicating a mismatch) indicating that the component on carrier tape 7 is not the correct component, feeder control unit 28 displays on operation display panel 29 that it is not the correct component to notify the worker.

[0094] In step S3, upon receiving the detection signal from the first sensor Sa1, the feeder control unit 28 rotates the second motor 23a in the forward direction. This rotates the second sprocket 23g, feeding the carrier tape 7 downstream. Note that the feeder control unit 28 may also perform step S3 at the timing when the lock unit 45 is released, thereby rotating the second motor 23a in the forward direction and feeding the carrier tape 7 downstream.

[0095] The carrier tape 7 is transported downstream in the tape transport path 20, and when the second sensor Sa2 detects the leading end of the carrier tape 7, a detection signal is sent to the feeder control unit .

[0096] In step S4, upon receiving a detection signal from the second sensor Sa2, the feeder control unit 28 reduces the rotational speed of the second motor 23a and stops the second motor 23a after a predetermined time has elapsed. As a result, the carrier tape 7 reaches the first sprocket 21a. Next, the feeder control unit 28 rotates the first motor 21b in the forward direction to rotate the first sprocket 21a, causing the first sprocket 21a to engage with the carrier tape 7. Thus, the carrier tape 7 is delivered to the first sprocket 21a. The feeder control unit 28 drives the first motor 21b to rotate, causing the first sprocket 21a to feed the carrier tape 7 at a predetermined pitch. In this way, the feeder control unit 28 switches the sprocket that feeds the carrier tape 7.

[0097] The carrier tape 7 is pitch-fed by the first sprocket 21a, and when the third sensor Sa3 detects the leading end of the carrier tape 7, it transmits a detection signal to the feeder control unit 28. Upon receiving the detection signal from the third sensor Sa3, the feeder control unit 28 stops the first motor 21b.

[0098] Next, in step S5, feeder control unit 28 rotates second motor 23a in the reverse direction to rotate ratchet gear 35a clockwise, causing lever 36 of tape holding release mechanism 34 to swing, second support portion 31 of tape holding unit 26 to move upward, and carrier tape 7 to drop onto second transport path 20d.

[0099] Next, in step S6, the feeder control unit 28 rotates the second motor 23a in the reverse direction for a predetermined time, and then stops the second motor 23a. At this timing, the feeder control unit 28 performs a peeling operation of the carrier tape 7.

[0100] Next, in step S7, feeder control unit 28 rotates second motor 23a in the forward direction to rotate ratchet gear 35a clockwise. This causes lever 36 of tape retention release mechanism 34 to swing back to its original position, and second support portion 31 of tape retention unit 26 to move downward to its original tape retention position. As a result, first tape 7p previously inserted into tape feeder 6 passes through second transport path 20d and tape transport path 20 and is engaged with first sprocket 21a. Therefore, while the components on first tape 7p are being removed by mounting head 4 of component mounting device 1, second tape 7s to supply the next component can be inserted into tape retention unit 26 at any time.

[0101] The tape feeder 6 of this embodiment is provided with a tape transport path 20 having a first transport path 20c, into which the carrier tape 7 is inserted, and a second transport path 20d located below the first transport path 20c, on the upstream side, and where the second transport path 20d and the first transport path 20c join to guide the running of the carrier tape 7 in the downstream direction. The tape feeder 6 further includes a first tape transport unit 21 that sequentially transports the carrier tape 7 on the tape transport path 20 downstream of a position P2 where the first transport path 20c and the second transport path 20d join to a component removal position P1 on the tape transport path 20, and a tape holding unit 26 that holds the carrier tape 7 in at least a portion of the first transport path 20c. The tape feeder 6 further includes a second tape transport unit 23 that transports the carrier tape 7 held by the tape holding unit 26 in the downstream direction of the tape transport path 20, and a tape retention release mechanism 34 that drops the carrier tape 7 held by the tape holding unit 26 from the first transport path 20c to the second transport path 20d. The tape retention release mechanism 34 operates using the power of the drive source of the second tape transport unit 23.

[0102] In this way, in the tape feeder 6 of the present embodiment, the tape holding release mechanism 34 automatically drops the carrier tape 7 inserted into the first transport path 20c into the second transport path 20d, preventing a component supply stop caused by an operator forgetting to release the tape. This makes it possible to improve the productivity of mounted boards and automate or reduce the labor required for component supply to component mounting devices.

[0103] In addition, the second tape transport unit 23 in this embodiment is equipped with a second motor 23a that can rotate forward and backward as a drive source, and when the second motor 23a rotates forward, the second tape transport unit 23 transports the carrier tape 7 in the downstream direction of the tape transport path 20, and when the second motor 23a rotates backward, it drives the tape holding release mechanism 34.

[0104] As a result, the second motor 23a of the second tape transport unit 23 that transports the carrier tape 7 is used as the drive source for the tape holding release mechanism 34, so that space within the tape feeder 6 can be saved.

[0105] In addition, in this embodiment, the tape holding portion 26 is displaceable from a holding position where it holds the carrier tape 7 to a release position P3 where it releases the hold on the carrier tape 7, and the tape holding release mechanism 34 displaces the tape holding portion 26 to the release position P3.

[0106] In addition, the tape holding release mechanism 34 of this embodiment includes a ratchet mechanism 35 that rotates by the driving force of the second motor 23a, and a lever 36 that swings by the ratchet mechanism 35, and the tape holding portion 26 is displaced to the holding position or the release position P3 by the swing of the lever 36.

[0107] As a result, the lever 36 is swung by the ratchet mechanism 35, so that the tape holding portion 26 can be maintained at the holding position or the release position P3 as long as the rotation direction of the second motor 23a does not change.

[0108] Furthermore, the tape feeder 6 of this embodiment is provided with a feeder control unit 28 that drives the tape holding release mechanism 34 at a timing after the carrier tape 7 transported by the second tape transport unit 23 is handed over to the first tape transport unit 21.

[0109] As a result, even if the carrier tape 7 is released from the first transport path 20c to the second transport path 20d, the carrier tape 7 has already been delivered to the first tape transport unit 21, so the carrier tape on the second transport path can be pitch-fed by the first tape transport unit 21 as a leading tape. Furthermore, since the carrier tape 7 can be inserted as a trailing tape into the tape holding unit 26, which is part of the first transport path 20c, productivity of mounted boards can be improved, and component supply to the component mounting device can be automated or labor-saving. The delivery of the carrier tape 7 from the second tape transport unit 23 to the first tape transport unit 21 may be performed in such a manner that both the first sprocket 21a and the second sprocket 23g of the first tape transport unit 21 are engaged with the carrier tape 7 on the downstream and upstream sides, respectively, or in such a manner that only the first sprocket 21a of the first tape transport unit 21 is engaged with the carrier tape 7.

[0110] Furthermore, tape feeder 6 of the present embodiment includes a first sensor Sa1 that detects that carrier tape 7 has been inserted into tape transport path 20, and a second sensor Sa2 that is located downstream of first sensor Sa1 on tape transport path 20 and detects that carrier tape 7 has arrived there. Tape feeder 6 also includes a third sensor Sa3 that is located downstream of second sensor Sa2 on tape transport path 20 and detects that carrier tape 7 has arrived at component take-out position P1. Feeder control unit 28 activates second tape transport unit 23 based on the detection result of first sensor Sa1 that the carrier tape 7 has been detected, stops second tape transport unit 23 at a predetermined timing after second sensor Sa2 detects carrier tape 7, and also activates first tape transport unit 21.

[0111] This makes it possible to detect the position of the carrier tape 7 being transported along the transport path 20, and to transfer the carrier tape 7 from the second tape transport unit 23 to the first tape transport unit 21 with high precision.

[0112] Furthermore, based on the detection result of the third sensor Sa3 detecting the carrier tape 7, the feeder control unit 28 of this embodiment stops the first tape transport unit 21 and drives the tape retention release mechanism 34. As a result, after the downstream side of the carrier tape 7 is handed over to the first tape transport unit 21, the first tape transport unit 21 stops and the tape retention release mechanism 34 is driven, so that the carrier tape 7 can be prevented from being released during transport and the path of the carrier tape 7 can be changed with high accuracy.

[0113] Furthermore, tape feeder 6 of the present embodiment transports carrier tape 7 containing components to supply the components to component mounting device 1. Tape feeder 6 is provided with shutter 27a, which is located downstream of second sprocket 23g on first transport path 20c, for preventing carrier tape 7 from being transported downstream from a predetermined position, and feeder control unit 28 for controlling the drive of second tape transport unit 23 based on the results of comparing information on components stored on carrier tape 7 with predetermined information on components to be supplied. Shutter 27a moves with carrier tape 7 transported by second tape transport unit 23 from tape stop position P4, where advancement of carrier tape 7 stops, to retract position P5 away from tape stop position P4.

[0114] This allows the feeder control unit 28 to control the transport of the carrier tape 7 based on the results of comparing the information on the parts stored on the carrier tape 7 with the information on the parts to be supplied, eliminating the need for the worker to further insert the carrier tape 7 after the comparison, thereby reducing the worker's waiting time and improving work efficiency.

[0115] In addition, the tape feeder 6 of this embodiment is equipped with a locking unit 45 that locks the shutter 27a, and the feeder control unit 28, based on the result of the comparison, causes the locking unit 45 to unlock the shutter 27a and causes the second tape conveying unit 23 to convey the carrier tape 7.

[0116] As a result, the feeder control section 28 releases the lock of the shutter 27a by the lock section 45 based on the result of the collation, so that only the carrier tape 7 containing the correct components can be conveyed.

[0117] Furthermore, tape feeder 6 of the present embodiment is provided with fourth sensor Sa4 that detects displacement of shutter 27a. The unlocked shutter 27a is displaced by carrier tape 7 transported along first transport path 20c, and feeder control unit 28 recognizes that carrier tape 7 has been replenished to tape feeder 6 based on the detection of displacement of shutter 27a by fourth sensor Sa4.

[0118] As a result, even after all the components on the first tape 7p have been supplied, the feeder control unit 28 is aware that the second tape 7s has already been set, and so can continuously supply components to the component mounting device 1.

[0119] Furthermore, tape feeder 6 of the present embodiment is equipped with: stop position P6, which has a contact portion 24aa that contacts the leading edge of second tape 7s at a predetermined position on first feed path 20c and stops second tape 7s at the predetermined position; stopper 24a that is movable from stop position P6 to stopper release position P7, which allows second tape 7s to be fed downstream; and lever 24b that moves stopper 24a to stop position P6 and stopper release position P7. When abutment portion 24aa moves from stop position P6 to stopper release position P7, it moves away from the leading edge of second tape 7s in the feed direction of second tape 7s.

[0120] This prevents the abutting portion 24aa from digging into the second tape 7s when it moves to the stopper release position P7, allowing the second tape 7s to be fed smoothly.

[0121] Furthermore, according to the tape feeder 6 of this embodiment, there is a fulcrum 24ac that rotatably supports the stopper 24a, the abutment portion 24aa is positioned downstream of the fulcrum 24ac in the conveying direction of the second tape 7s, and the lever 24b rotates the stopper 24a upward.

[0122] This allows the abutting portion 24aa to properly separate from the leading end of the second tape 7s in the feeding direction of the second tape 7s when the abutting portion 24aa moves from the predetermined position to the stopper release position P7.

[0123] Furthermore, according to tape feeder 6 of the present embodiment, lever 24b has tip portion 24bb including a link, and stopper 24a has tip portion 24ab that receives power from tip portion 24bb.

[0124] This allows the driving force of the lever 24b to be appropriately transmitted to the stopper 24a.

[0125] Although the present disclosure has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, various variations and modifications will be apparent to those skilled in the art. Such variations and modifications are to be understood as being included within the scope of the present disclosure as defined by the appended claims, unless they depart therefrom. Furthermore, changes in the combination and order of elements in each embodiment may be made without departing from the scope and spirit of the present disclosure.

[0126] (1) In the above embodiment, the tape retention release mechanism 34 presses down the movable member 33 using the lever 36, but this is not limited to this. As shown in Figures 21 and 22, the movable member 33 may be lifted up by the lever 36 using a link mechanism. In Figure 21, the movable member 33 is in a position where the carrier tape 7 is held by the second support part 31. In Figure 22, the movable member is lifted up by the lever 36 and is in a position where it will drop from the second support part 31.

[0127] (2) In the above embodiment, the carrier tape 7 held by the tape holding unit 26 is released by the upward movement of the movable member. However, this is not limited to this. The up-and-down movement of the lever 36 may be converted into lateral movement using, for example, a cam mechanism. As shown in FIG. 23 , the tape holding unit 26A includes a left side wall 32a to which the first support member 30 is fixed and a right side wall 32b to which the second support member 31 is fixed. FIG. 23 is an explanatory diagram illustrating the release of the carrier tape 7 in a modified example. (a) shows a state in which the carrier tape 7 is being held, (b) shows a state in which the carrier tape 7 falls due to the displacement of the left side wall 32a and the right side wall 32b, and (c) shows a state in which the left side wall 32a and the right side wall 32b have returned to their original tape holding positions. The tape holding release mechanism 34 displaces the left side wall 32a and the right side wall 32b to displace the first support member 30 and the second support member 31 to a release position P3 laterally separated from the first transport path 20c.

[0128] In this way, when the tape holding portion 26A causes the carrier tape 7 to fall by displacing the left side wall 32a and the right side wall 32b, the lengths of the first support portion 30 and the second support portion 31 can be increased, making it suitable for transporting a wide carrier tape 7.
