The tape transport path 60 widens in the vicinity of the tape entrance 23a on the upstream side of the tape transport path 60, and a tape support portion 62b is arranged to divide the tape transport path 60 into two in this widened space. Therefore, in a state where the leading end of the next tape 24b is supported by the tape support portion 62b at the upstream end of the tape transport path 60, the current tape 24a is placed on the bottom surface 60a of the tape transport path 60 below the tape support portion 62b. It can be conveyed downstream along. Further, the next tape 24b supported by the tape support portion 62b can be moved to the bottom surface 60a of the tape transport path 60 by the drive portion 62c moving the carry-in sprocket 62a and the tape support portion 62b.

The drive unit 62c includes, for example, a motor as a power source and a power transmission member that transmits the power of the power source to the carry-in sprocket 62a. A power transmission member is, for example, a gear. A power transmission mechanism combining a link mechanism, gears, elastic members, etc., for moving the carry-in sprocket 62a and the tape support portion 62b in the direction of the arrow a2 using the power of another power source may also be provided.

The component supply unit 23 includes a first sensor PH1, a second sensor PH2, and a third sensor PH3 arranged in order from the upstream side along the tape transport path 60.

The first sensor PH1 detects that the carrier tape 24 inserted into the tape support portion 62b of the component supply unit 23 has reached the first checkpoint provided at the downstream end of the tape support portion 62b.

The second sensor PH2 detects the presence or absence of the carrier tape 24 at a second check point provided downstream of the first check point and near the confluence with the tape transport path 60 on the extension of the tape support portion 62b. .

The third sensor PH3 detects the presence or absence of the carrier tape 24 at a third checkpoint provided downstream of the exposed portion 66 of the tape transport path 60 and upstream of the component pick-up position 23ba. The first sensor PH1 to the third sensor PH3 are optical sensors that directly or indirectly detect the presence or absence of the carrier tape 24 at each checkpoint, and are, for example, color sensors or photosensors.

When the end of the current tape 24a passes the third checkpoint and the third sensor PH3 no longer detects the carrier tape 24, the carry-in sprocket 62a rotates and the next tape 24b supported by the tape support portion 62b moves downstream. transported to

When the leading edge of the next tape 24b passes through the third checkpoint and the third sensor PH3 detects the next tape 24b, the driving portion 62c moves the tape support portion 62b to move the next tape 24b to the tape transport path 60 at the tape entrance 23a. move to

The tape support portion 62b supports the next tape 24b and maintains the posture in which the next tape 24b is conveyed. See FIG. The tape support portion 62b is composed of a first support portion 62ba and a second support portion 62bb. A thin plate-like left cover 62bcL and a right cover 62bcR are mounted on both side surfaces of the component supply unit 23 so as to sandwich the tape transport path 60 from the left and right. The upper end of the right cover 62bcR is interrupted at a position lower than the tape support portion 62b, and a thin plate-like movable member 62bd is arranged above it so as to complement the right cover 62bcR. Hereinafter, for the sake of convenience, as shown in FIG. 8, when facing the downstream direction in which the carrier tape 24 is conveyed in the component supply unit 23, one side is the left side and the other side is the right side.

The left cover 62bcL extends in the tape feeding direction and the vertical direction (Z direction). The inner side surface (right side surface) of the left cover 62bcL is a guide surface that guides the left side surface of the next tape 24b. The left cover 62bcL is fixed to the left surface of the main body 23d of the component supply unit 23. As shown in FIG. Similarly, the right cover 62bcR is also fixed to the right surface of the main body 23d of the component supply unit 23. As shown in FIG.

The first support portion 62ba supports one side of the carrier tape 24 in the width direction from below. The first support portion 62ba is formed on the right side surface of the left cover 62bcL and extends below the shutter unit 63 from the tape entrance 23a. The second support portion 62bb supports the other side portion of the next tape 24b from below. The second support portion 62bb is formed on the left side surface of a movable member 62bd, which will be described later, extends downstream from the tape entrance 23a, and ends before the shutter unit 63. As shown in FIG.

The movable member 62bd has a plate-like shape and is attached to the main body 23d of the component supply unit 23 so as to be vertically movable. The movable member 62bd is mounted integrally with the loading sprocket 62a, and when it moves vertically, the loading sprocket 62a also moves vertically. The inner surface of the movable member 62bd is a guide surface that guides the right side surface of the next tape 24b. The movable member 62bd is moved vertically (arrow a2 in FIG. 8) by the driving portion 62c.

Next, the function of discharging the next tape 24b from the tape support portion 62b to the tape transport path 60 will be described. As shown in FIG. 9A, when the movable member 62bd is at the initial position and the second support portion 62bb is at the same height as the first support portion 62ba, the next tape 24b is placed on the tape support portion 62b. held. When releasing the next tape 24b from the tape support portion 62b, the unit control portion 64 drives the drive portion 62c to move the movable member 62bd upward. As a result, the second support portion 62bb and the carry-in sprocket 62a are lifted together.

As the movable member 62bd rises, the carrier tape 24 moves upward while being supported by the second support portion 62bb on the lower surface of the right side, and the pin 62aa of the carry-in sprocket 62a is disengaged from the feed hole 54 of the carrier tape 24, counterclockwise. twist in the direction

As shown in FIG. 9(b), when the movable member 62bd is further raised, the twist of the carrier tape 24 increases, and eventually the carrier tape 24 slides down from the first support portion 62ba and the second support portion 62bb.

The next tape 24b released from the tape support portion 62b moves to the bottom surface 60a of the tape transport path 60 below the tape support portion 62b. When the carrier tape 24 (next tape 24b) is separated from the tape support portion 62b, the next carrier tape 24 (next tape 24b) can be inserted into the tape support portion 62b at any time.

《Shutter unit》
Next, the shutter unit 63 will be described with reference to FIG. 10A and 10B are side views showing the configuration of the shutter unit. FIG. 10A shows a state in which the carrier tape 24 has not reached the shutter unit 63, and FIG. indicates a state of being stopped by

The shutter unit 63 prevents the carrier tape 24 supported by the tape support portion 62b from proceeding further to the downstream side of the tape transport path 60. The shutter unit 63 has a tape detection mechanism 63a and a gate unit 63b.

The tape detection mechanism 63 a detects that the carrier tape 24 supported by the tape support portion 62 b has reached the shutter unit 63 . The tape detection mechanism 63a includes a tape detection piece 71, a pin 72, and a first sensor PH1.

The tape detection piece 71 has a substantially L shape, and includes a plate-like portion 71a extending facing the tape support portion 62b, a contact portion 71b extending from the upstream side of the plate-like portion 71a toward the tape support portion 62b, It has a light blocking portion 71c extending from the downstream end of the plate-like portion 71a in the opposite direction (upward) to the direction of the tape support portion 62b. The tape detection piece 71 is attached to the main body 23d of the component supply unit 23 so as to be able to swing around a fulcrum 71d provided near the upstream end. The plate-like portion 71a is supported from below by a pin 72 fixed downstream of the fulcrum 71d. The contact portion 71b protrudes from the plate-like portion 71a of the tape detection piece 71 toward the first support portion 62ba, and the lower end of the contact portion 71b contacts the tip portion of the carrier tape 24 moving along the upper surface of the first support portion 62ba. located in an accessible position. The position of the contact portion 71b is the first checkpoint for detecting the carrier tape 24. As shown in FIG.

The first sensor PH1 is arranged above the light shielding portion 71c. As shown in FIG. 10B, when the carrier tape 24 advances downstream along the tape support portion 62b, the tip of the carrier tape 24 pushes the contact portion 71b downstream, and the tape detection piece 71 moves toward the fulcrum 71d. rotate counterclockwise around the As a result, the light blocking portion 71c blocks the light emitted from the first sensor PH1, and the first sensor PH1 transmits a detection signal to the unit control portion 64. FIG. This makes it possible to detect that the carrier tape 24 has reached the shutter unit 63 (arrived at the first checkpoint).

As shown in FIG. 10(a), the gate unit 63b includes a gate 74, a compression spring 75, a lock member 76, a lever 77, an actuator 78, and a return spring 79. The gate unit 63b controls whether the carrier tape 24 supported by the tape support portion 62b is advanced further downstream in the tape transport path 60 according to an instruction from the unit control portion 64 or is stopped.

The gate 74 is, for example, a plate-like member, and one end of the compression spring 75 is connected to its upper end. The gate 74 is urged by a compression spring 75 toward the first support portion 62ba. Therefore, the lower end of the gate 74 is in contact with the upper surface of the first support portion 62ba.

A lock member 76 prevents the gate 74 from rising against the spring force of the compression spring 75 . The locking member 76 is, for example, a laterally extending rod, and one end thereof is laterally inserted into a recess 74 a formed in the side surface of the gate 74 .

The lever 77 is attached to the main body 23d of the component supply unit 23 so as to be swingable about a fulcrum 77a arranged in the center. A lock member 76 is fixed to one end (lower end) of the lever 77 . The other end (upper end) of lever 77 is connected to rod 78 a of actuator 78 . One end of a return spring 79 is connected between the fulcrum 77 a of the lever 77 and one end of the lever 77 .

The actuator 78 expands and contracts the rod 78a according to instructions from the unit control section 64. A return spring 79 biases lever 77 in a pulling direction, i.e., biasing it to rotate clockwise. As a result, the tip of the lock member 76 is inserted into the concave portion 74 a on the side surface of the gate 74 by the return spring 79 . When the lock member 76 is inserted into the recess 74a on the side surface of the gate 74, upward movement of the gate 74 is restricted and the gate 74 is locked. On the other hand, when the actuator 78 is actuated to swing the lever 77 counterclockwise against the spring force of the return spring 79, the lock member 76 is disengaged from the recess 74a and the gate 74 can be moved upward. , that is, the lock is released.

Next, the operation of the shutter unit will be described with reference to FIGS. 10 to 12. FIG. 11A and 11B are side views showing the configuration of the shutter unit. FIG. 11A shows a state in which the locking member is unlocked, and FIG. 11B shows a state in which the carrier tape 24 passes through the shutter unit 63. indicates FIG. 12 shows a state in which the carrier tape 24 has fallen from the tape support portion 62b.

As shown in FIG. 10(a), the carrier tape 24 is inserted from the tape entrance 23a along the tape support portion 62b and advances in the downstream direction. Next, as shown in FIG. 10(b), when the tip of the carrier tape 24 contacts the contact portion 71b of the tape detection piece 71, the contact portion 71b is pushed downstream, and the tape detection piece 71 moves toward the fulcrum 71d. It oscillates counterclockwise as the central axis. As a result, the light blocking portion 71c of the tape detection piece 71 blocks the optical path of the first sensor PH1, and the first sensor PH1 transmits a detection signal to the unit control portion 64. FIG.

After the contact portion 71b of the tape detection piece 71 swings, the tip of the carrier tape 24 contacts the gate 74 and pushes the gate 74 upward. The gate 74 is pushed upward by the carrier tape 24, but the wall surface of the concave portion 74a of the gate 74 abuts against the lock member 76 to prevent the gate 74 from rising. Therefore, the gate 74 prevents the carrier tape 24 from entering the tape transport path 60 in the downstream direction.

Next, when the carrier tape 24 is conveyed downstream of the gate 74 , the unit control section 64 drives the actuator 78 to unlock the gate 74 .

When the actuator 78 is driven, the rod 78a extends toward the lever 77 and the lever 77 swings counterclockwise as shown in FIG. 11(a). As a result, the lock member 76 is separated from the recess 74a of the gate 74, and the lock of the gate 74 is released. This allows the gate 74 to move upward. After driving the actuator 78, the unit control section 64 drives the carry-in sprocket 62a. As a result, the carrier tape 24 starts to be transported in the downstream direction, and the carrier tape 24 moves toward the downstream side of the tape transport path 60 while pushing up the gate 74 as shown in FIG. 11(b). Note that the unit control section 64 stops driving the actuator 78 at an appropriate timing after the leading edge of the carrier tape 24 has passed through the gate 74 .

See Figure 8. When the carrier tape 24 is transported in the downstream direction of the tape transport path 60 and transported to the third transport sprocket 61c, the carrier tape 24 is detected by the third sensor PH3. The third sensor PH3 transmits a detection signal indicating detection of the carrier tape 24 to the unit control section 64 . When the unit control section 64 receives the detection signal from the third sensor PH3, it recognizes that the downstream side of the carrier tape 24 is conveyed by the third conveying sprocket 61c. The unit control section 64 then drives the drive section 62c to move the carry-in sprocket 62a and the tape support section 62b in the arrow a2 direction. This causes the carrier tape 24 to drop from the tape support portion 62b and move to the bottom surface 60a of the tape transport path 60, as shown in FIG. 12 and as already described above. When the carrier tape 24 drops from the tape support portion 62b, the gate 74 is pressed against the first support portion 62ba by the compression spring 75, and the lock member 76 is inserted into the concave portion 74a of the gate 74 by the return spring 79. As a result, the gate 74 is locked.

The unit control section 64 drives the drive section 62c to move the tape support section 62b, and then returns the tape support section 62b to its original position. The actuator 78 is driven to contract the rod 78a.

When the carrier tape 24 drops from the tape support portion 62b, the tape detection piece 71 swings clockwise about the fulcrum 71d, and the plate-like portion 71a comes into contact with the pin 72 and stops swinging. As a result, the light blocking portion 71c is removed from the first sensor PH1, so that no detection signal is output to the unit control portion 64. FIG. Thereby, the unit control section 64 recognizes that the carrier tape 24 is not supported by the tape support section 62b or that the carrier tape 24 does not exist at the first check point.

《Exposed part》
Next, the exposed portion 66 will be described with reference to FIG. 13 . FIG. 13 is a side view showing the configuration of the exposed portion 66. As shown in FIG. 13(a) shows a state in which the carrier tape 24 has passed through the exposed portion 66, and FIG. 13(b) shows a state in which the carrier tape 24 has turned back the exposed portion 66. FIG. In this specification, "advance" of the carrier tape 24 means that the carrier tape 24 is conveyed in the downstream direction, and "reverse" of the carrier tape 24 means that the carrier tape 24 is conveyed in the upstream direction. means

Since the top tape 52 is made of a film-like material with extremely low rigidity, the extending portion 52 a is bent at the leading end 51 a of the base tape 51 in the tape transport path 60 . In this specification, the state in which the extending portion 52a is bent at the leading end 51a of the base tape 51 and partially overlapped with the carrier tape 24 upstream of the leading end is referred to as "curling". In the overlapped state, the extending portion 52a of the top tape 52 may be in contact with the top tape 52 attached to the upper surface of the base tape 51, or may be in non-contact. In addition, "correcting the turn-up" and "correcting the bending" refer to returning the extending portion 52a bent at the leading end 51a of the base tape 51 to extend forward (downstream) from the leading end 51a of the base tape 51. It also includes the case where the extending portion 52a of the top tape 52 is not fully extended forward.

An exposed portion 66 is arranged on the inclined portion of the tape transport path 60 on the upstream side and obliquely below the component pick-up position 23ba. The exposed portion 66 separates the top tape 52 of the carrier tape 24 from the base tape 51 to expose the upper surface of the component 5 stored in the pocket 53 . The exposed portion 66 includes a pair of

rollers

81 and 82 for feeding the top tape and a drive mechanism for driving these

rollers

81 and 82 . The drive mechanism of the exposed portion 66 has a motor as a drive source and a drive transmission mechanism such as gears for transmitting the rotational power of the motor to the

rollers

81 and 82 . By controlling the driving mechanism of the exposure portion 66 by the unit control portion 64, the

rollers

81 and 82 are rotated, whereby the peeling operation of the top tape 52 described below is executed.

The

rollers

81 and 82 are provided, for example, above the tape transport path 60 and communicate with the tape transport path 60 through an opening 83 that opens toward the top surface 60b of the tape transport path 60 . The extending portion 52 a of the top tape 52 of the carrier tape 24 conveyed along the tape conveying path 60 from the upstream side is drawn into the

rollers

81 and 82 through the opening 83 and separated from the base tape 51 . The newly set carrier tape 24 is sent from the tape entrance 23a of the tape transport path 60 in a state in which the leading end 52b of the top tape 52 is longer than the leading end 51a of the base tape 51 (having an extension portion 52a). When the tip of the carrier tape 24 reaches the opening 83 , the extension 52 a of the top tape 52 is captured by the exposed portion 66 .

That is, the exposed portion 66 draws in the extending portion 52a at the tip of the top tape 52 by sandwiching it between the

rollers

81 and 82 . As a result, the top tape 52 is separated from the base tape 51 of the carrier tape 24 . The peeled top tape 52 is fed in a direction away from the base tape 51 . In the following description, after the top tape 52 is peeled from the base tape 51, the base tape 51 from which the top tape 52 is peeled is also referred to as a carrier tape 24.

A third sensor PH3 is arranged downstream of the position where the exposed portion 66 is arranged. The third sensor PH3 is, for example, a transmission detection type optical sensor, and detects the carrier tape 24 transported along the tape transport path 60 . A detection result by the third sensor PH3 is sent to the unit control section 64 . The tip of the carrier tape 24 is detected by providing a dog that can be in mechanical contact with the tip of the carrier tape 24 and detecting the displacement of the dog when the carrier tape 24 contacts the dog with an optical sensor. You may If the method uses an optical sensor to detect the displacement of the dog, it is possible to reliably detect the carrier tape 24 even if the carrier tape 24 is made of a light transmissive material.

On the side of the bottom surface 60 a of the tape transport path 60 , an air nozzle 84 for ejecting air is arranged at a position facing the opening 83 with the air ejection direction directed toward the opening 83 . The air nozzle 84 is a jetting portion that jets air, and the jetted air hits the extending portion 52a of the top tape 52 located near the opening 83, and the force of the jetted air hits the extending portion 52a of the top tape 52. toward the exposed portion 66 . That is, the air nozzle 84 assists the exposed portion 66 to capture the top tape 52 and guides the tip of the top tape 52 to the exposed portion 66 . The air nozzle 84 is supplied with air from an air supply section (not shown).

By controlling the air supply section with the unit control section 64, air can be jetted from the air nozzle 84 toward the exposed section 66 at any timing. In the present embodiment, the curling of the top tape 52 is corrected, and the unit control section 64 ejects air from the air nozzle 84 at the timing when the extended portion 52a reaches a position where it can be captured by the exposed portion 66. controlling. For example, when the third sensor PH3 detects the leading edge of the carrier tape 24, the third conveying sprocket 61c may send the carrier tape 24 upstream for a predetermined distance or for a predetermined period of time before injecting air. While the carrier tape 24 is moved in the reverse direction for a predetermined distance or for a predetermined period of time, the curling of the top tape 52 is corrected, and the extension 52a is moved below the opening 83. As shown in FIG.

By blowing the air jetted by the air nozzle 84 onto the extending portion 52a, the extending portion 52a is pressed against one of the rollers 81 located downstream. Then, the

rollers

81 and 82 are rotated in the directions of the arrows shown in FIG. 14(a), and the extending portion 52a pressed against the roller 81 is sandwiched between the

rollers

81 and 82 and captured. Then, the top tape 52 is peeled off from the base tape 51 by continuing the rotation of the

rollers

81 and 82 to pull the top tape 52 away from the base tape 51 .

At this time, the jetting direction of the air nozzle 84 is set so that the jetted air is blown from below the carrier tape 24 to the extending portion 52a.

In FIG. 8, the unit control section 64 is communicably connected to the driving section 61d, the exposed section 66 and the third sensor PH3. That is, the tape transport operation of transporting the carrier tape 24 along the tape transport path 60 is executed by the unit control section 64 controlling the third transport sprocket 61c. At this time, the unit control section 64 can control the transport timing and transport amount of the carrier tape 24 .

Further, the unit control section 64 controls the

rollers

81 and 82 and the air supply section based on the detection signal of the third sensor PH3, thereby performing a peeling operation for peeling the top tape 52 from the base tape 51 of the carrier tape 24. be done. In this peeling operation, the top tape 52 is captured by the exposed portion 66 by injecting air from the air nozzle 84 .

An operating section is communicably connected to the unit control section 64, and the unit control section 64 is communicably connected to the main body section 2 of the component mounting apparatus 1. The tape conveying operation and the tape feeding operation described above are executed according to an operation command input from the operation unit and a control command transmitted from the main unit 2 .

Next, a tape peeling method for peeling the top tape 52 from the base tape 51 of the carrier tape 24 in the component supply unit 23 configured as described above will be described with particular reference to FIGS. 13 and 14. FIG.

The carrier tape 24 inserted into the tape entrance 23a is transported downstream along the tape transport path 60 by the loading sprocket 62a of the tape loading section 62. When the carrier tape 24 reaches the third conveying sprocket 61c of the tape conveying section 61 located downstream of the tape conveying path 60 (FIG. 15(b)), the carrier tape 24 is conveyed by the tape conveying section 61 thereafter. will be While the carrier tape 24 is transported downstream along the tape transport path 60, the top tape 52 is turned over. During this tape transport, the

rollers

81 and 82 are rotating in a direction in which the top tape 52 can be pinched and captured at the exposed portion 66 arranged on the inclined portion of the tape transport path 60 .

In the course of this tape transport, a detection step is performed in which the leading edge of the carrier tape 24 transported on the tape transport path 60 is detected by the third sensor PH3, and the detection result is sent to the unit control section 64. Then, based on this detection result, a correction process for correcting the curling of the top tape 52 is performed. The correction process is performed by the tape conveying section 61 . After the curling of the top tape 52 is corrected, a peeling process is performed to peel the top tape 52 from the carrier tape 24 by the exposed portion 66 provided on the upstream side of the tape transport path 60 . During this peeling process, a gas injection process is executed in which air, which is a gas for trapping the extended portion 52a of the top tape 52 in the exposed portion 66, is injected toward the exposed portion 66 by an air nozzle 84, which is an injection portion. be done.

At the timing when the extending portion 52a (tip portion) of the top tape 52 reaches a position where it can be peeled off by the exposed portion 66, the unit control portion 64 controls the air supply portion to execute the gas injection process. As a result, the air jetted from the air nozzle 84 hits the extending portion 52 a of the carrier tape 24 .

The extending portion 52a of the top tape 52 extending from the leading end 51a of the base tape 51 is turned over below the base tape 51 as shown in FIG. 13(a). The top fold of the cover tape that is turned over occurs. Even if air is injected from the air nozzle 84 to the top tape 52 in this state, the extending portion 52 a cannot be blown up, so the extending portion 52 a of the top tape 52 cannot be guided to the exposed portion 66 .

As shown in FIG. 13( a ), the third transport sprocket 61 c moves the carrier tape 24 forward so that the tip of the extension 52 a of the top tape 52 is located downstream of the air nozzle 84 . The unit control section 64 controls the third conveying sprocket 61c to convey the carrier tape 24 until it receives a detection signal of the carrier tape 24 from the third sensor PH3 arranged downstream of the air nozzle 84. may

Next, when the third sensor PH3 detects the carrier tape 24, the unit control section 64 stops feeding the carrier tape 24 based on this detection signal and feeds it backward, that is, moves the carrier tape 24 toward the tape entrance 23a. The third transport sprocket 61c is controlled to transport to. As a result, the third transport sprocket 61c rotates in the reverse direction, and the carrier tape 24 moves backward by a predetermined distance in the upstream direction as shown in FIG. 13(b).

As shown in FIG. 13(b), when the third transport sprocket 61c feeds the carrier tape 24 in the reverse direction, the extension 52a of the top tape 52 is straightened. stretched into a shape. After detecting the carrier tape 24 by the third sensor PH3, the carrier tape 24 is reversed for a predetermined time by measuring the timer so that the top tape 52 is turned up.

After the carrier tape 24 is fed backward for a predetermined time, the unit control section 64 again feeds (forwards) the carrier tape 24 in the forward direction by a predetermined distance (predetermined time). The extension 52a of tape 52 can be positioned below the center of exposed portion 66 (between rollers 81 and 82).

At this timing, the unit control section 64 jets air from the air nozzle 84 to blow the leading end 52b of the top tape 52 against the

rollers

81 and 82 to send the extended portion 52a of the top tape 52 to the exposed portion 66, as shown in FIG. As shown in a), the

rollers

81 and 82 rotate while sandwiching the top tape 52 . In this way, the top tape 52 can be peeled off from the base tape 51 completely automatically. As shown in FIG. 14(b), when the carrier tape 24 advances further, the

rollers

81 and 82 also rotate accordingly, the top tape 52 is peeled off, and the component 5 stored in the pocket 53 of the carrier tape 24 is removed. exposed.

Thus, the curling of the top tape 52 can be corrected simply by feeding the carrier tape 24 backward. When the carrier tape 24 is reversed, the air in the tape transport path 60 hits the extending portion 52a of the top tape 52, and the base tape 51 moves upstream with respect to the leading end 52b of the top tape 52. As shown in FIG. When correcting the curling of the top tape 52 by feeding the carrier tape 24 backward, it is necessary to correct the curling of the top tape 52 on the upstream side of the center of the exposed portion 66 that captures the tip of the top tape 52 .

The exposed component 5 is conveyed by the tape conveying section 61 together with the carrier tape 24 to the opening formed downstream thereof, that is, the component pick-up position 23ba (see FIGS. 16(a) and 16(b)). An opening is formed at a position corresponding to the component extraction position 23ba.

Next, the carrier tape conveying operation by the component supply unit 23 will be described with reference to FIGS. 15 to 17. FIG.

See FIG. 15(a). The operator inserts the carrier tape 24 along the tape support portion 62b arranged at the tape entrance 23a of the component supply unit 23 whose lamp 23f is blinking. When the operator inserts the carrier tape 24, the switch 23g of the component supply unit 23 is pressed. When the current tape 24a is present on the downstream side of the tape transport path 60, the tape loading section 62 loads the carrier tape 24 while the gate 74 of the gate unit 63b is locked, and the carrier tape 24 is detected by the first sensor PH1. Then, the carry-in sprocket 62a is stopped. If the operator inserts the carrier tape 24 to the position detected by the first sensor PH1, the tape loading section 62 does not operate. In either case, the carrier tape 24 cannot enter deeper than the gate 74 .

If there is no carrier tape 24 on the downstream side of the tape transport path 60 when the operator presses the switch 23g, the gate 74 is unlocked when the switch 23g is pressed, and the tape loading section 62 moves to the carrier in this state. The tape 24 is transported. As a result, the carrier tape 24 pushes up the gate 74 with its leading end and is fed into the tape transport path 60 . As shown in FIG. 15(b), when the carrier tape 24 is transported to a position where it hits the pin of the third transport sprocket 61c, the loading by the loading sprocket 62a stops. The carrier tape 24 is conveyed further downstream by the third conveying sprocket 61c, and when detected by the third sensor PH3, the tape conveying portion 61 causes the exposed portion 66 to capture the top tape 52. FIG.

When the exposed portion 66 captures the top tape 52, the carrier tape 24 is transported further downstream while the top tape 52 is peeled off by the exposed portion 66 and the third transport sprocket 61c. When the pins of the second transport sprocket 61b are inserted into the feed holes 54 of the carrier tape 24, the drive unit 61d drives the second transport sprocket 61b to move the top of the carrier tape 24 as shown in FIG. 16(a). The pocket 53 is positioned at the component pick-up position 23ba.

Next, the tape loading section 62 changes the running path. As shown in FIG. 16B, the carrier tape 24 passing through the tape loading section 62 drops out of the tape loading section 62 due to the change of the running path and moves to the bottom surface 60a of the tape transport path 60 below. Note that the change of the running path is executed at the timing when the carrier tape 24 is engaged with the second transport sprocket 61b and the third transport sprocket 61c of the tape transport unit 61. FIG. Also, when the lane is changed, the gate 74 moves downward and is locked.

As shown in FIG. 17(a), the operator can insert the carrier tape 24 (next tape 24b) to be used next into the tape loading section 62 that has become vacant due to the change of track. The method of inserting the carrier tape 24 into the tape loading section 62 is the same as the method already described above.

As shown in FIG. 17(b), when the carrier tape 24 runs out of components and the passage of the end of the carrier tape 24 is detected by the second sensor PH2, the tape conveying unit 61 discharges the carrier tape 24. (eject tape). If the passing of the end of the carrier tape 24 is not detected at the time when the lack of components is detected, the end search is performed, and then the tape is ejected. After the current tape 24a has been unloaded, the gate 74 is unlocked, and the tape loading section 62 transports the next tape 24b in this state. As a result, the next tape 24b is fed into the tape transport path 60 by pushing up the gate 74 with its leading edge. When the next tape 24b is transported to a position where it hits the pin of the most upstream third transport sprocket 61c of the tape transport section 61, the transport by the transport sprocket 62a stops. After that, the running path is changed, and the next tape 24b is conveyed as the current tape 24a.

《Tape Cassette》
Next, referring to FIG. 18, the tape cassette 22 will be described. 18(a), 18(b), and 18(c) are side sectional views of the tape cassette 22 showing how the roll body 25 of the carrier tape 24 is taken in and out of the tape cassette 22 used as the storage cassette 22B. be.

When the roll body 25 is stored in the tape cassette 22, the roll body 25 is inserted through the opening 41b opened in front of the storage section 41 with the shutter 42 positioned at the open position (FIG. 18A). 18(b)), and the operating lever 86 is moved downward (arrow shown in FIG. 18(b)). As a result, the shutter 42 moves from the open position to the closed position, the opening 41b of the storage section 41 is closed by the shutter 42, and the roll body 25 is stored in the tape cassette 22 (FIG. 18(b)).

On the other hand, when the roll body 25 stored in the tape cassette 22 is taken out, or when the carrier tape 24 pulled out from the roll body 25 loaded and stored in the storage cassette mounting portion 39 is used in the component supply unit 23, the operating lever 86 is moved upward (an arrow shown in FIG. 18(c)). As a result, the shutter 42 moves from the closed position to the open position, the opening 41b of the storage section 41 is opened, and the roll body 25 can be taken out from the storage section 41 (arrow shown in FIG. 18(c)). .

As described above, in this embodiment, the tape cassette 22 as a storage device includes a storage portion 41 having a space 41a for storing the roll body 25 and an opening 41b through which the roll body 25 can be taken in and out, and the opening 41b.

If the pulled-in carrier tape 24 is the next tape 24b, the next tape 24b is put on standby until it is detected that the end of the current tape 24a has passed the third checkpoint in the component supply unit 23. When the end of the current tape 24a passes the third checkpoint, the storage section 41 of the receiving cassette 22A is empty. When the component supply unit 23 starts transporting the next tape 24b, the roll 25 of the next tape 24b stored in the storage cassette 22B is pulled by the next tape 24b transported by the component supply unit 23 and rolls forward. , moves into the storage portion 41 of the receiving cassette 22A positioned in front thereof (FIG. 19(a)→FIG. 19(b)).

When the roll body 25 stored in the storage cassette 22B moves into the receiving cassette 22A, the storage cassette 22B becomes empty. The empty storage cassette 22B is removed from the carriage 21 (cassette mounting portion 46a) in order to mount the roll body 25 (storage cassette 22B) of the carrier tape 24 to be used next. After the supply of the components 5 by the component supply unit 23 has progressed, the operator mounts a new tape cassette 22 in the cassette mounting portion 46a according to the procedure described above.

《Set-up station》
Next, the processing performed at the setup station 94 will be described with reference to FIG. FIG. 26 is a diagram showing the configuration of the setup station 94. As shown in FIG.

The setup work is the work of setting the component supply unit 23 used in manufacturing the board 4 on which the component 5 is mounted and the tape cassette 22 containing the component 5 in the component supply unit 3 . The setup work performed on the spare component supply section 3 that is not attached to the component mounting apparatus 1 is called "outside setup work", and the setup work performed on the component supply section 3 attached to the component mounting apparatus 1 is called "outside setup work". It is called "internal setup work". The set-up operations performed at set-up station 94 are out-of-setup operations and are described below.

By mounting the component supply unit 23 and the tape cassette 22 on the carriage 21 and connecting the carriage 21 to the docking section 131 of the setup station 94, external setup work for the component supply unit 23 and the tape cassette 22 can be carried out. . The component supply unit 23 and the tape cassette 22 that have completed the external setup work can be moved together with the carriage 21 and connected to the main body 2 of the component mounting apparatus 1 . Thus, when changing the type of the board 4 to be produced, the setup work of the component supply unit 3 can be completed in advance, so that the board 4 to be produced can be changed quickly.

The setup station 94 can communicate with the component supply unit 23, the receiving cassette 22A, and the storage cassette 22B by connecting the connector 21a of the carriage 21 and the docking portion 131.

The setup section 137 includes a cassette detection section 161 , a cassette determination section 162 , a unit notification section 163 , a permission section 164 and an information update section 165 .

The cassette detection unit 161 detects the tape cassette 22 and transmits a detection signal to the cassette determination unit 162 when the tape cassette 22 is mounted on the receiving cassette mounting unit 38 and the storage cassette mounting unit 39 of the carriage 21 . . The cassette detection unit 161 detects that the tape cassette 22 is attached to the cassette attachment unit 46a corresponding to the wireless communication unit 29 by changing from the state in which the wireless communication unit 29 does not detect the wireless tag 28 to the state in which the wireless tag 28 is detected. to detect

When the reader/

writers

29a and 29b as the wireless communication unit 29 detect the wireless tag 28 in their reception range, they output a signal (cassette detection signal) notifying that they are ready to communicate with the wireless tag 28. The cassette detector 161 of the present embodiment detects that the tape cassette 22 is attached to the receiving cassette attaching portion 38 or the storage cassette attaching portion 39 using the wireless tag detecting function of the reader/

writers

29a and 29b. Further, the cassette detector 161 identifies the position (mounting location) of the mounted tape cassette 22 based on the cassette detection signals received from the reader/

writers

29a and 29b. The cassette detection unit 161 refers to the connection information 152 to specify the component supply position number corresponding to the connection port to which the cassette detection signal has been sent as information indicating the mounting location of the tape cassette 22 .

The cassette determination unit 162 determines whether or not the mounted tape cassette 22 is the tape cassette 22 containing the correct carrier tape 24 . For example, the cassette determination unit 162 compares the position where the tape cassette 22 is installed, the component information from the wireless tag 28 of the installed tape cassette 22, and the information defined in the production program 112, and determines whether the tape cassette 22 is installed. It is determined whether the selected tape cassette 22 is correct. The production program 112 stored in the storage unit 105 includes setup information designating the parts to be arranged in the cassette mounting unit 46a. The cassette determination unit 162 outputs a correct determination signal when determining that the mounted tape cassette 22 is correct, and an erroneous determination signal when determining that the mounted tape cassette 22 is incorrect. Send to

Upon receiving the correct determination signal, the unit notification section 163 flashes the lamp 23f of the component supply unit 23 into which the carrier tape 24 is to be inserted, notifying the operator that the correct tape cassette 22 has been loaded and the carrier tape. The component supply unit 23 into which the 24 should be inserted is notified. When receiving the erroneous determination signal, the unit notification section 163 flashes the lamp 23f of the component supply unit 23 in a pattern or color different from that of the correct determination to notify the operator that the wrong tape cassette 22 has been loaded. inform.

Upon receiving the positive determination signal, the permitting section 164 gives permission to supply the carrier tape 24 to the component supply unit 23 by sending the permission signal to the component supply unit 23 . The component supply unit 23 that has received the permission signal from the permission unit 164 waits until it becomes possible to start pulling in the carrier tape 24 . The operator inserts the carrier tape 24 into the component supply unit 23 whose lamp 23f is flashing as a result of the positive determination, and presses the switch 23g of the component supply unit 23 to notify completion of the component supply work. The component supply unit 23 starts to pull in the carrier tape 24 after confirming the two events of the reception of the permission signal and the operation of the switch 23g by the operator. The component supply unit 23 does not pull in the carrier tape 24 if the two events cannot be confirmed within a predetermined time. As a result, the operator can be made aware that the carrier tape 24 has been erroneously inserted into another component supply unit 23, thereby preventing the wrong component from being supplied. Note that the unit notification section 163 can be activated by using a configuration in which the unit notification section 163 and the permission section 164 are integrated, that is, by using a command transmitted from the unit notification section 163 to the component supply unit 23 for blinking the lamp 23f as a permission signal. It may function as the permission unit 164 .

The information updating unit 165 updates the information of the wireless tag 28 at the timing when the next tape 24b is pulled in and becomes the current tape 24a. When the information of the wireless tag 28 is updated by the information updating unit 165, the cassette management information 111 of the management device 92 is also updated.

A plurality of wireless communication units 29 , a storage unit 105 storing a production program 112 including setup information, and a setup station 94 constitute a setup support device 97 .

Next, the setup work for the current tape 24a will be described with reference to FIGS. 26 to 29. FIG. FIG. 27 is a flow chart showing the processing (preparation work) of the preparatory section 137 during preparatory work for the current tape 24a. 28 and 29 are explanatory diagrams showing the component supply section 3 during setup work for the current tape 24a.

As shown in FIG. 26, the setup section 137 refers to the production program 112 of the mounting board scheduled to be produced, and causes the monitor 133 to display the type of the component supply unit 23 and the component supply position number. The operator looks at the monitor 133 and mounts the component supply unit 23 at the location corresponding to the corresponding component supply position number, as shown in FIG. 28(a). Also, the operator mounts an empty tape cassette 22 in the receiving cassette mounting portion 38 at the position corresponding to the corresponding component supply position number.

Next, as shown in FIG. 28(b), based on the setup information displayed on the monitor 133 by the setup section 137, the operator sets the storage cassette 22B containing the roll body 25 of the predetermined part 5 to the storage cassette. It is attached to the attachment portion 39 .

When the storage cassette 22B is attached to the storage cassette attachment portion 39 of the carriage 21, the setup portion 137 detects that the storage cassette 22B has been attached in step ST1 shown in FIG. Specifically, the reader/writer 29b detects and communicates with the wireless tag 28 of the storage cassette 22B. The cassette detector 161 receives a cassette detection signal from the reader/writer 29b and detects that the storage cassette 22B is attached (Yes in step ST1). When the storage cassette 22B is not attached to the storage cassette attachment portion 39 of the carriage 21, the cassette detection portion 161 does not receive the cassette detection signal from the reader/writer 29b (No in step ST1). Keep sending radio signals. When the cassette detection unit 161 detects the cassette mounting, in step ST2, the cassette detection unit 161 identifies the mounting location of the mounted storage cassette 22B. Note that the information updating unit 165 updates the location information of the cassette management information 111 when the mounting location of the storage cassette 22B is identified.

In step ST3, the cassette determination unit 162 reads the component information of the mounted storage cassette 22B from the wireless tag 28 by the reader/writer 29b. Instead of the cassette detection unit 161, the cassette determination unit 162 may specify the cassette mounting unit 46a in which the tape cassette 22 is mounted. In step ST4, the cassette determination unit 162 refers to the production program 112 to confirm the correspondence between the mounting location of the mounted storage cassette 22B and the component information.

In step ST5, the cassette determination unit 162 determines whether the correspondence relationship between the mounting location of the mounted storage cassette 22B and the read component information matches the contents of the setup information of the production program 112. is loaded or not.

In step ST5, when the cassette determination section 162 determines that the correspondence relationship between the mounting location and the part information matches the content of the production program 112 (Yes in step ST5), the unit notification section 163 inserts the next tape 24b in step ST6. The lamp 23f of the component supply unit 23 to be processed is blinked.

In step ST7, the permitting section 164 transmits to the unit control section 64 a permitting signal for permitting the loading of the carrier tape 24 into the component supply unit 23. 29A, when the operator inserts the carrier tape 24 into the tape entrance 23a and presses the switch 23g of the component supply unit 23, a switch signal is sent to the unit control section 64. FIG.

In step ST8, when the unit control section 64 receives two signals, the permission signal from the permission section 164 and the switch signal from the switch 23g, it starts loading the next tape 24b stored in the storage cassette 22B. In addition, the unit control section 64 turns off the lamp 23 f and outputs a start signal indicating the start of loading of the carrier tape 24 to the setup section 137 . If the unit control section 64 cannot receive these two signals, it waits for the loading of the next tape 24b (No in step ST8) and waits for the arrival of the two signals.

When the loading of the next tape 24b starts (Yes in step ST8), the roll body 25 stored in the storage cassette 22B moves from the storage cassette 22B to the empty receiving cassette 22A. When the setup section 137 receives the start signal from the unit control section 64, in step ST9, the part information read from the wireless tag 28 of the storage cassette 22B by the information updating section 165 is used as the part information of the wireless tag 28 of the receiving cassette 22A. The part information of the radio tag 28 of the empty storage cassette 22B is erased. The information updating section 165 further updates the cassette management information 111 stored in the storage section 105 of the management device 92 . Specifically, the information in the cassette ID column of the storage cassette 22B is copied to the cassette ID column of the receiving cassette 22A, and the information in the cassette ID column of the storage cassette 22B is deleted.

By updating the component information of the wireless tag 28 of the receiving cassette 22A, the component information of the roll body 25 of the component 5 stored in the receiving cassette 22A is recorded in the wireless tag 28 of the receiving cassette 22A. Even when production of substrates 4 is discontinued, trace information of roll 25 in receiving cassette 22A can be maintained.

In step ST10, the setup section 137 determines whether the setup work for all the component supply units 23 that require setup for the current tape 24a has been completed. When the setup section 137 determines that the setup work for the current tape 24a has not been completed (No in step ST10), the process is repeated again from step ST1. When the setup section 137 determines that the setup work for the current tape 24a is completed (Yes in step ST10), the setup section 137 causes the monitor 133 of the setup station 94 to display a message for the setup work for the current tape 24a. Notify the worker of the completion of setup work.

Further, in step ST5, when the cassette determination unit 162 determines that the correspondence relationship between the mounting location and the part information does not match the contents of the production program 112 (No in step ST5), in step ST11, the monitor 133 of the setup station 94 , to display a confirmation message telling the operator to confirm the mounting location.

At step ST12, the cassette determination unit 162 detects whether or not the storage cassette 22B displaying the confirmation message has been removed. When the cassette determination unit 162 detects that the storage cassette 22B displaying the confirmation message has been removed (Yes in step ST12), the process of step ST10 is performed. When the removal of the storage cassette 22B for which the confirmation message is displayed is not detected (No in step ST12), the cassette determination unit 162 returns to step ST11 and displays a confirmation message to the monitor 133 to tell the operator to confirm the mounting location. continue to display

Next, the preparation work for the next tape 24b will be described with reference to FIGS. 30 and 31. FIG. FIG. 30 is a flowchart showing the processing (preparation work) of the preparatory section 137 during preparatory work for the next tape 24b. 31A and 31B are explanatory diagrams showing the component supply unit 3 during the setup work for the next tape 24b, and FIGS. 31A and 31B are process diagrams of the setup work for the next tape 24b.

As shown in FIG. 31( a ), the receiving cassette 22 A containing the current tape 24 a pulled into the tape transport path 60 of the component supply unit 23 is already mounted on the receiving cassette mounting portion 38 of the carriage 21 . The operator removes the empty storage cassette 22B from the storage cassette mounting section 39, and based on the setup information displayed on the monitor 133 by the setup section 137, the storage cassette 22B containing the roll body 25 of the predetermined part 5 is removed. is attached to the storage cassette attachment portion 39 .

In the flow chart of FIG. 30, steps ST21 to ST27, steps ST30 and ST31 are the same processes as steps ST1 to ST7, steps ST11 and ST12 of the flow chart of FIG.

The setup section 137 executes steps ST21 to ST27 as shown in FIGS. At step ST27, when the operator inserts the carrier tape 24 into the tape loading section 62 and presses the switch 23g of the component supply unit 23, a switch signal is sent to the unit control section 64. FIG. As shown in FIG. 31(c), upon receiving the switch signal from the switch 23g, the unit control section 64 rotates the carry-in sprocket 62a to advance the next tape 24b stored in the storage cassette 22B. Further, the unit control section 64 turns off the lamp 23f.

When the next tape 24b advances, the tip of the next tape 24b contacts the contact portion 71b of the tape detection piece 71 and the gate 74, and is detected by the first sensor PH1. In this way, the unit control section 64 causes the next tape 24b to be carried in to the position detected by the first sensor PH1, and the state in which the leading edge of the next tape 24b is in contact with the gate 74 is maintained.

In step ST28, the setup section 137 determines whether or not the worker has completed the work. Upon receiving two signals, the switch signal from the switch 23g and the detection signal from the first sensor PH1, the setup section 137 determines that the work by the worker has been completed. If the two signals are not received, the setup section 137 determines that the work by the worker has not been completed (No in step ST28), and executes step ST28 again after a predetermined period of time has elapsed.

When the setup unit 137 determines that the work by the worker has been completed (Yes in step ST28), in step ST29, the setup unit 137 sets up the next tapes 24b of all the component supply units 23 that require setup of the next tapes 24b. Determine whether the work has been completed. When the setup section 137 determines that the setup work for the next tape 24b has not been completed (No in step ST29), the process is repeated again from step ST1. When the setup section 137 determines that the setup work for the next tape 24b is completed (Yes in step ST29), the setup section 137 causes the monitor 133 of the setup station 94 to display a message for the setup work for the next tape 24b. The operator is notified of the completion of the setup work for the next tape 24b.

《Information update at the time of tape switching in component mounting equipment》
Next, a configuration in which the current tape 24a is used up and the next tape 24b is newly supplied as the current tape 24a in the component mounting apparatus 1 during the component mounting operation will be described with reference to FIG. FIG. 32 is an explanatory diagram showing the configuration of the component mounting apparatus 1. As shown in FIG.

The component depletion determination unit 144 of the main body control unit 17 determines whether or not the current tape 24a has run out of components. Empty pockets 53 continue on the downstream end of the carrier tape 24 . Therefore, when the nozzle 13a of the mounting head 13 fails to pick up the component 5 from the current tape 24a a predetermined number of times in succession, the component depletion determining unit 144 determines that the component is depleted.

Also, in addition to the above-described conditions for continuous removal failure of the component 5, the remaining number of components in the cassette management information 111 may be used for determination. Since there is a possibility of an erroneous judgment only with the above conditions, the judgment system can be improved by referring to the remaining number of parts. When the nozzle 13a of the mounting head 13 fails to pick up the component 5 from the current tape 24a a predetermined number of times in succession, the component depletion determining unit 144 determines that the component is depleted under the above-described conditions if the remaining number of components is equal to or less than the predetermined number. If there are many remaining parts, it is determined that there is no shortage of parts. If it is judged that the parts are not out of stock, it is dealt with as a mere trouble. Further, the parts shortage determination unit 144 may determine whether or not the current tape 24a has run out of parts based only on the remaining number of parts in the cassette management information 111 .

When the component depletion determination unit 144 determines that the current tape 24a is depleted of components, the operation control unit 143 discharges the empty current tape 24a, controls the driving unit 62c of the component supply unit 23, and supplies the next tape. 24b is used as the next current tape 24a, and the switching operation is performed.

The information updating unit 145, like the information updating unit 165, updates the information of the wireless tag 28 at the timing when the next tape 24b is pulled in and becomes the current tape 24a. When the information of the wireless tag 28 is updated by the information updating unit 145, the cassette management information 111 of the management device 92 is also updated.

Next, referring to FIG. 33, the operation of updating information by switching tapes in the component mounting apparatus 1 will be described. FIG. 33 is a flow chart showing the flow of information update processing in the component mounting apparatus 1. FIG.

First, a component supply step is performed to transport the current tape 24a of the receiving cassette 22A and supply the components 5 to the component pick-up position 23ba. Before long, all the parts packed by the current tape 24a are supplied, and the current tape 24a runs out of parts.

When the component depletion determining unit 144 determines that the current tape 24a has run out of components, it transmits a determination signal and the mounting location (component supply position number) of the component supply unit 23 in which the current tape 24a is set to the operation control unit. 143. In step ST<b>32 , upon receiving the determination signal, the operation control section 143 transmits a tape switching command to the corresponding component supply unit 23 . Upon receiving the tape switching command, the component supply unit 23 advances the next tape 24b and starts switching operation to change the next tape 24b to the current tape 24a (Yes in step ST32). As a result, the component supply unit 23 performs a tape loading step in which the next tape 24b is loaded from the storage cassette 22B. If the operation control unit 143 does not receive the determination signal from the component depletion determination unit 144, it does not transmit the tape switching command to the component supply unit 23, so the switching operation to change the next tape 24b to the current tape 24a is not started. (Yes in step ST32), the component supply unit 23 continues the component supply step from the current tape 24a.

In step ST33, the information updating unit 145 updates the component supply position number of the component supply unit 23 whose switching operation of the next tape 24b is started from the mounting location (component supply position number) transmitted from the component depletion determination unit 144. Identify. Further, the information updating unit 145 recognizes that the component supply unit 23 has started conveying the carrier tape 24 from the storage cassette 22B based on the signal indicating the mounting location transmitted from the component depletion determination unit 144 . The information updating unit 145 further identifies the reader/writer 29 a and the reader/writer 29 b associated with the identified component supply unit 23 based on the connection information 152 .

In step ST34, the information updating section 145 copies the component information read from the wireless tag 28 of the storage cassette 22B as the component information of the wireless tag 28 of the receiving cassette 22A. In this case, the part information is copied using the reader/writer 29a and the reader/writer 29b connected to the connection port belonging to the part supply position number identified in step ST33. As the information to be copied, all of the information contained in the wireless tag 28 of the receiving cassette 22A may be copied as long as it contains the parts information, or part of the parts information may be copied.

In this manner, in conjunction with the start of transport of the carrier tape 24 from the storage cassette 22B by the component supply unit 23, the information updating section 145 updates the information stored in the wireless tag 28 of the receiving cassette 22A through the reader/writer 29a. Update. The timing at which the information updating unit 145 interlocks with the start of transport of the carrier tape 24, that is, the timing at which the information is updated is a predetermined time after the start of the switching operation using a timer from the start of the switching operation of the next tape 24b. It may be any timing before or just before the leading component 5 reaches the component picking position 23ba.

In step ST35, the information update section 145 erases the component information of the wireless tag 28 of the empty storage cassette 22B.

In step ST36, the information update section 145 further updates the cassette management information 111 stored in the storage section 105 of the management device 92. In this way, the information update by tape switching is completed.

Note that the information updating unit 145 copies the component information read from the wireless tag 28 of the storage cassette 22B in accordance with the switching operation of the next tape 24b as the component information of the wireless tag 28 of the receiving cassette 22A. A different method may be used to update the part information of the wireless tag 28 of the receiving cassette 22A. Specifically, the component information (component ID) of the storage cassette 22B having the same component supply position number as the component supply position number of the receiving cassette 22A whose component information is to be updated in the cassette management information 111 is read, and the read component The information (part ID) may be copied onto the radio tag 28 of the receiving cassette 22A.

《Parts replenishment work》
Next, referring to FIG. 34, the parts replenishment work will be described. If the components 5 are continuously mounted on the substrate 4, the number of the components 5 decreases, and the component supply section 3 needs to replenish the components 5. - 特許庁Therefore, the management device 92 identifies the parts 5 that are expected to run out and issues replenishment instructions. FIG. 34 is a diagram showing a configuration related to parts replenishment work.

The component replenishment work support device 98 supports the component replenishment work of installing the storage cassette 22B containing the replenishment carrier tape 24 in the cassette mounting portion 46a. The component replenishment work support device 98 includes a

storage unit

105 or 142 storing setup information regarding the arrangement of the components 5 on the cassette base 46, a component replenishment instruction unit 103, a replenishment cassette detection unit 171, and a replenishment cassette determination unit 172. Configured. In the following description, the component replenishment work support device 98 is described as a component of the component mounting device 1, but may be configured as a separate device from the component mounting device 1. FIG.

The management device 92 refers to the production program 112 and the production results 113 to recognize the remaining number of parts required to produce the planned number of mounting boards. The management device 92 acquires from the production program 112 the planned production number of mounted boards and the number of each component 5 to be mounted on one board 4 (the number of components per board). The actual production record 113 includes the number of substrates 4 on which component mounting work has been completed (number of production). The management device 92 obtains the remaining number of necessary parts from the planned production quantity, the number of parts per board, and the production quantity. The management device 92 refers to the remaining number of required parts and the remaining number of parts of the roll body 25 stored in the receiving cassette 22A and the storage cassette 22B with reference to the cassette management information 111. FIG. When the management device 92 determines that parts replenishment is necessary, the parts replenishment instruction unit 103 selects replenishable parts from the actual production record 113, the production program 112 (scheduled production quantity), the remaining number of parts, and the state of the parts supply unit 23. Identify. When the parts that can be replenished are identified, the parts replenishment instruction unit 103 notifies the worker by transmitting information indicating the contents of the parts replenishment work to the portable information terminal 95 carried by the worker. When replacing the storage cassette 22B or removing the carrier tape 24 from the roll body 25 stored in the storage cassette 22B and inserting it into the component supply unit 23 by an automatic replenishment means such as a transport robot instead of the operator, a component replenishment instruction is issued. A unit 103 instructs the automatic replenishment means to replenish parts.

The supply unit state detection section 146 of the main body control section 17 detects the component supply unit 23 in a state capable of holding the next tape 24b. Such a component supply unit 23 is in the state shown in FIG. 16(b), or is the component supply unit 23 in which no carrier tape 24 is attached.

The parts replenishment support unit 147 includes a replenishment cassette detection unit 171 , a replenishment cassette determination unit 172 , and a replenishment permission unit 173 .

The supplementary cassette detection unit 171 detects the attachment of the storage cassette 22B to the storage cassette attachment unit 39. Similar to the cassette detection section 161, the supplementary cassette detection section 171 also detects that the storage cassette 22B is attached to the storage cassette attachment section 39 using the wireless tag detection function of the reader/

writers

29a and 29b. Further, the supplementary cassette detection unit 171 identifies the position (mounting location) of the mounted storage cassette 22B based on the cassette detection signal received from the reader/writer 29b. By referring to the connection information 152, the cassette detection unit 161 identifies the component supply position number corresponding to the connection port to which the cassette detection signal has been sent as information indicating the mounting position of the storage cassette 22B.

The replenishment cassette determination unit 172 determines whether or not the storage cassette 22B attached to the storage cassette attachment unit 39 by the operator contains the correct carrier tape 24 . For example, the replenishment cassette determination unit 172 compares the position where the storage cassette 22B is installed, the component information acquired from the wireless tag 28 of the installed storage cassette 22B, and the setup information defined in the production program 112. to determine whether or not the installed storage cassette 22B is correct. Another determination method by the replenishment cassette determination unit 172 is to read the parts information stored in the wireless tag 28 of the storage cassette 22B and the parts information stored in the wireless tag 28 of the receiving cassette 22A, and may be compared to determine if the appropriate storage cassette 22B has been installed.

When the replenishment cassette determination unit 172 determines that the appropriate storage cassette 22B is loaded, the replenishment permission unit 173 instructs the unit control unit 64 of the component supply unit 23 to set the carrier tape 24 in the storage cassette 22B. Send a permission signal to indicate acceptance permission.

Next, the flow of parts replenishment work will be described with reference to FIG. FIG. 35 is a flowchart showing the processing (parts replenishment work) of the parts replenishment support unit 147 during the parts replenishment work. Note that the flowchart of FIG. 35 assumes that the operator performs the parts replenishment work. In principle, the flow chart uses the parts information stored in the wireless tag 28 of the storage cassette 22B and the parts information stored in the wireless tag 28 of the receiving cassette 22A to determine the storage cassette 22B by the replenishment cassette determination unit 172. are assumed to be compared.

When the parts replenishment instruction unit 103 of the management device 92 identifies replenishable parts, it transmits information indicating the details of the parts replenishment work to the portable information terminal 95 carried by the worker. The operator confirms the contents of the parts replenishment work displayed on the portable information terminal 95, and selects the empty storage cassette 22B mounted in the storage cassette mounting section 39 of the designated parts supply section 3 and the parts to be replenished. Replace with the stored storage cassette 22B. As a result of this replacement, the supplementary cassette detection section 171 detects that a new storage cassette 22B has been attached to the storage cassette attachment section 39 in step ST41. If the supplementary cassette detection unit 171 has not detected that a new storage cassette 22B has been installed in the storage cassette installation unit 39 (No in step ST41), it waits until the replacement is completed.

When the supplementary cassette detection unit 171 detects the mounting of the storage cassette 22B (Yes in step ST41), the mounting location of the storage cassette 22B is identified in step ST42. The supplementary cassette detector 171 refers to the connection information 152 to specify the component supply position number corresponding to the connection port to which the cassette detection signal has been sent as information indicating the mounting position of the mounted tape cassette 22 .

In step ST43, the supplementary cassette determination unit 172 reads the component information of the storage cassette 22B via the reader/writer 29b.

In step ST44, the supplementary cassette determination unit 172 reads the component information of the receiving cassette 22A via the reader/writer 29a.

In step ST45, the replenishment cassette determination unit 172 determines whether or not there is component information on the receiving cassette 22A. If there is no parts information for the receiving cassette 22A (Yes in step ST45), the parts information stored in the wireless tag 28 of the storage cassette 22B is compared with the parts information stored in the wireless tag 28 of the receiving cassette 22A. In this case, the setup information of the production program 112 is referred to in step ST51.

If the supplementary cassette determination section 172 determines in step ST45 that there is component information for the receiving cassette 22A (NO in step ST45), or if the supplementary cassette determination section 172 refers to the setup information in step ST51, in step ST46, The supplementary cassette determination unit 172 determines whether the parts information of the receiving cassette 22A matches the parts information of the storage cassette 22B. When referring to the setup information in step ST51, the replenishment cassette determination unit 172 determines that the corresponding relationship between the mounting location (component supply position number) of the mounted storage cassette 22B and the read component information is the contents of the setup information of the production program 112. It is determined whether or not it matches with

If they match (Yes in step ST46), in step ST47, the component replenishment support unit 147 lights the lamp 23f of the component supply unit 23 to which the component 5 is to be replenished and notifies the operator. In this manner, the component replenishment support section 147 and the lamp 23f constitute a replenishment target notification section that notifies the operator of the component supply unit 23 in which the carrier tape 24 of the storage cassette 22B should be set.

In step ST48, the replenishment permission section 173 transmits a permission signal for loading the carrier tape 24 to the unit control section 64 of the component supply unit 23.

In step ST49, the parts replenishment support unit 147 determines whether or not the parts replenishment work by the worker has been completed. If the completion of the work cannot be confirmed (No in step ST49), the parts replenishment support unit 147 waits for an instruction to complete the work from the worker. When the worker presses the switch 23g and the parts replenishment support unit 147 can confirm the completion of the work (Yes in step ST49), in step ST50, the parts replenishment instruction unit 103 determines whether or not there is a part replenishment work for other parts. judge.

If there is another part 5 to be replenished (Yes in step ST50), the process from step ST41 is repeated. If there is no replenishment of the next part 5 (No in step ST50), the part replenishment work is terminated.

Also, if there is no match in step ST46 (No in step ST46), a message is displayed on the portable information terminal 95 to instruct the installation location of the storage cassette 22B to be confirmed in step ST52.

In step ST53, when the supplementary cassette detection unit 171 detects removal of the cassette (Yes in step ST53), the process of step ST50 is performed. If removal of the cassette has not been detected (No in step ST53), the process of step ST52 is performed again.

The flowchart of the processing (parts replenishment work) of the parts replenishment support unit 147 shown in FIG. It is assumed that the part information stored in the wireless tag 28 of 22A is compared, but if the processing of step ST46 is unified to the method of comparing with the setup information of the production program 112, the following changes are made. be done. The flowchart after the change deletes the processing of steps ST44 and ST45, and is changed so that the processing is performed in the order of step ST51 and step ST46 following step ST43. The processing contents of steps ST51 and ST46 are the same as those described above. In this way, it is also possible to unify the determination of the storage cassette 22B by the replenishment cassette determination unit 172 to the method of comparing it with the information of the production program 112 .

The component mounting apparatus 1 of this embodiment is a cassette having a space 41a for accommodating a roll body 25 of a carrier tape 24 packed with components 5 and an opening 41b through which at least the roll body 25 can be taken in and out from the space 41a. 22, a receiving cassette 22A and a storage cassette 22B provided with a wireless tag 28, and the carrier tape 24 of the receiving cassette 22A are conveyed to supply the component 5 to the component pick-up position 23ba, followed by the carrier tape 24 and the storage cassette 22B. a component supply unit 23 for conveying the carrier tape 24 and supplying the components 5 to the component pick-up position 23ba; a mounting slot 31a for mounting the component supply unit 23; A supply unit base 31 provided with a plurality of supply unit mounting portions 31b having a side connector 30, and a plurality of component supply units 23 mounted on the supply unit base 31 pick up components 5 from component take-out positions 23ba and mount them on a board 4.
