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 pickup 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.

The tape support portion 62b supports the carrier tape 24 and maintains the posture in which the carrier tape 24 is conveyed. Please refer to 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. 6, 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 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 carrier tape 24. As shown in FIG. The movable member 62bd is moved vertically (arrow a2 in FIG. 6) by the driving portion 62c.

Next, the function of discharging the carrier tape 24 from the tape support portion 62b to the tape transport path 60 will be described. As shown in FIG. 7A, 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 carrier tape 24 is placed on the tape support portion 62b. held. When releasing the carrier tape 24 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. 7B, when the movable member 62bd rises further, 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 carrier tape 24 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 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.

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 of the component supply unit 23 so as to be swingable 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. 8B, 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.

As shown in FIG. 8(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. As shown in FIG. 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 lock member 76 is, for example, a rod, one end of which is laterally inserted into a recess 74a formed in the side surface of the gate 74. As shown in FIG.

The lever 77 is attached to the main body 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 locking member 76 extends laterally toward a recess 74 a formed in the side of the gate 74 . 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 78 a 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, operation of the shutter unit will be described with reference to FIGS. 8 to 10. FIG. 9A and 9B are side views showing the structure of the shutter unit. FIG. 9A shows a state in which the locking member is unlocked, and FIG. 9B shows a state in which the carrier tape 24 passes through the shutter unit 63. indicates FIG. 10 shows a state in which the carrier tape 24 has fallen from the tape support portion 62b.

As shown in FIG. 8A, 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. 8B, 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, causing the tape detection piece 71 to move 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 transported 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. 9(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. 9B. 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 .

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. 10 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. 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 around 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. 11 . FIG. 11 is a side view showing the configuration of the exposed portion 66. As shown in FIG. FIG. 11(a) shows a state in which the carrier tape 24 has passed through the exposed portion 66, and FIG. 11(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 tip 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 of the base tape 51 and partially overlaps the carrier tape 24 on the upstream side 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. Further, "correcting the turn-up" and "correcting the bending" mean that the extending portion 52a bent at the leading end of the base tape 51 is returned to a state extending forward (downstream) from the leading end of the base tape 51. This means that the extending portion 52a of the top tape 52 does not fully extend forward.

An exposed portion 66 is arranged on an inclined portion of the tape transport path 60 on the upstream side and diagonally 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 . The driving mechanism of the exposure portion 66 is controlled by the unit control portion 64 to rotate, and the roller 81 rotates, 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 upper 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 carrier tape 24 to be newly set is sent from the tape inlet 2a 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 of the base tape 51 (the state in which the extended portion 52a is provided). 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 pulls the extension portion 52a at the tip of the top tape 52 between the rollers 81 and 82. As shown in FIG. 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.

An air nozzle 84 for ejecting air is arranged at a position facing the opening 83 on the side of the bottom surface 60 a of the tape transport path 60 so that the air ejection direction is 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 opening and closing of a control valve 70 (FIG. 13) connected to the air supply section by the unit control section 64, air can be jetted from the air nozzle 84 toward the exposed section 66 at an arbitrary 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 against the extending portion 52a, the extending portion 52a is pressed against one of the rollers 81 located on the downstream side. Then, the rollers 81 and 82 are rotated in the directions of the arrows shown in FIG. 12(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. 6, the unit control section 64 is communicably connected to the driving section 61d, the exposed section 66, and the third sensor PH3, and controls the driving section 61d and the exposed section 66. 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 operation 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. 11 and 12. FIG.

The carrier tape 24 inserted into the tape entrance 23a is conveyed downstream along the tape conveying path 60 by the carry-in sprocket 62a of the second tape conveying section 62. As shown in FIG. When the carrier tape 24 reaches the third transport sprocket 61c of the first tape transport section 61 located on the downstream side of the tape transport path 60 (FIG. 15(b)), the transport of the carrier tape 24 thereafter is performed by the first tape transport. 61. 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 .

During this tape transport process, a detection step is executed to detect the leading edge of the carrier tape 24 transported on the tape transport path 60 by the third sensor PH3, and the detection result is sent to the unit controller 64. FIG. 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 first 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 where the top tape 52 extends from the tip of the base tape 51 is folded below the base tape 51 as shown in FIG. Folding occurs on the cover tape that can be turned over. 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. 11A, the third transport sprocket 61c advances the carrier tape 24 so that the tip of the extension 52a of the top tape 52 is located downstream of the air nozzle 84. As shown in FIG. 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. 11(b).

As shown in FIG. 11(b), when the third transport sprocket 61c feeds the carrier tape 24 in reverse, the extension 52a of the top tape 52 is corrected, and 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 transports (forwards) the carrier tape 24 in the forward direction by a predetermined distance (predetermined time) (step S4), as shown in FIG. 11(b). Thus, the extension portion 52 a of the top tape 52 can position the tip of the carrier tape 24 below the center of the exposed portion 66 .

At this timing, the unit control section 64 jets air from the air nozzle 84 to blow the leading end of the top tape 52 against the roller 81 to send the extended portion 52a of the top tape 52 to the exposed portion 66, as shown in FIG. 12(a). As shown, 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. 12(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 is transported by the first tape transport 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, a configuration of a component mounting system 100 including the component mounting apparatus 1 will be described with reference to FIG. 13 . FIG. 13 is a block diagram showing an example of the configuration of the component mounting system 100. As shown in FIG.

A network 96 connects the management apparatus 92 and the component mounting apparatus 1 so as to be able to communicate with each other.

FIG. 14 is a diagram showing an example of the parts management information 108. As shown in FIG.

The parts management information 108 shown in FIG. 14 stores information on each of "reel ID", "part name", "remaining number", "tape position", and "feeder address" as a plurality of types of information.

“Reel ID” is identification information for identifying the reel 22 containing the carrier tape 24 . The “component name” is information indicating the name of the component 5 held by the carrier tape 24 accommodated in the reel 22 . The “remaining number” is information indicating the remaining number of components 5 held by the carrier tape 24 . "Tape position" is information indicating in which state the carrier tape 24 is used, the current tape 24a or the next tape 24b. “Feeder address” is identification information indicating in which mounting slot the reel 22 is mounted in the feeder base 31 . If the tape position and feeder address are blank, reel 22 is not loaded in component supply unit 23 on feeder base 31 .

Returning to FIG. 13 , the body control section 17 of the component mounting apparatus 1 includes a plurality of processing sections and a body storage section 142 . The body control unit 17 can be realized by a semiconductor element or the like. The body control unit 17 can be configured by a circuit such as a microcomputer, CPU, MPU, GPU, DSP, FPGA, or ASIC, for example. The functions of the body control unit 17 may be configured only by hardware, or may be realized by combining hardware and software. The body control unit 17 reads data and programs stored in the body storage unit 142 and performs various arithmetic processing, thereby realizing predetermined functions.

The main body control unit 17 includes a component mounting work execution unit 143, a remounting detection unit 144, a first component information update unit 145, a second component information update unit 146, and a removal tape confirmation unit 147 as a plurality of processing units. .

The remounting detector 144 detects that the component supply unit 23 has been remounted on the feeder base 31 . For example, the remounting detection unit 144 detects remounting of the component supply unit 23 in response to receiving a predetermined signal from the component supply unit 23 mounted on the feeder base 31 .

The first parts information updating unit 145 updates used parts information in the host storage unit 104 of the management device 92 and the feeder storage unit 162 (to be described later) according to the state of the carrier tape 24 in the parts supply unit 23 being mounted on the feeder base 31 . The information stored in the storage unit 164 is updated. The first parts information update unit 145 includes an upper update unit 145A and a lower update unit 145B.

The second component information update unit 146 carries the component information of the carrier tape 24 attached to the component supply unit 23 in response to the reattachment of the component supply unit 23 being detected by the reattachment detection unit 144 . The operator is requested to obtain the part information by the mold information terminal 95, and the information in the feeder storage unit 162, which will be described later, is updated based on the part information obtained by this request.

The removed tape confirmation unit 147 compares the parts management information 108 in the upper storage unit 104 with the parts information in the used parts information storage unit 164 in the feeder storage unit 162, and determines whether any parts that may have been removed from the parts supply unit 23 are detected. The presence or absence of the carrier tape 24 is confirmed. In the carrier tape 24, although the component management information 108 indicates that the component supply unit 23 attached to the feeder address within the management target range is in use, the component supply unit 23 actually attached to the feeder address is in use. Some of them are not stored in the used part information storage unit 164 of . In this case, the removed tape confirmation unit 147 determines that the carrier tape 24 (and the corresponding reel ID) is the removed tape removed from the component supply unit 23 .

The body storage unit 142 stores various information related to the component mounting apparatus 1 such as the production program 151 . The main storage unit 142 can be implemented by, for example, a hard disk (HDD), SSD, RAM, DRAM, ferroelectric memory, flash memory, magnetic disk, or a combination thereof.

The tape transport control section 160 controls feeding operation of the carrier tape 24 attached to the component supply unit 23 based on a command from the body control section 17 .

The feeder storage unit 162 stores various information regarding the component supply unit 23 . The feeder 162 can be implemented by, for example, a hard disk (HDD), SSD, RAM, DRAM, ferroelectric memory, flash memory, magnetic disk, or a combination thereof.

The used component information storage unit 164 stores component information of the carrier tape 24 attached to the component supply unit 23 . Used component information storage unit 164 includes first storage unit 164A and second storage unit 164B. The first storage unit 164A stores component information of the current tape 24a attached to the component supply unit 23, and the second storage unit 164B stores component information of the next tape 24b attached to the component supply unit 23. do. By providing the first storage unit 164A and the second storage unit 164B, it is possible to manage the component information of the current tape 24a and the component information of the next tape 24b.

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

Please refer to FIG. 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 where the lamps 36, 37 (FIG. 5) of the operation panel 18 are blinking. After inserting the carrier tape 24 , the operator presses the operation switch 33 ( FIG. 5 ) of the component supply unit 23 . When the current tape 24a is present on the downstream side of the tape transport path 60, the second tape transport section 62 loads the carrier tape 24 while the gate 74 of the gate unit 63b is locked. is detected, 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 second tape conveying section 62 does not operate. In either case, the carrier tape 24 cannot enter deeper than the gate 74 . In this manner, the carrier tape 24 waits at a standby position 23bb located upstream of a component take-out position 23ba, which will be described later.

If there is no carrier tape 24 on the downstream side of the tape transport path 60 when the operator presses the operation switch 33, the lock of the gate 74 is released when the operation switch 33 is pressed, and the second tape transport is carried out in this state. A portion 62 conveys the carrier tape 24 . 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 first tape conveying section 61 causes the exposed section 66 to capture the top tape 52. FIG.

When the exposed portion 66 catches the top tape 52, the carrier tape 24 is further conveyed downstream while the top tape 52 is peeled off by the exposed portion 66 and the third conveying 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 second tape transport section 62 changes the running path. As shown in FIG. 16(b), the carrier tape 24 passing through the second tape conveying section 62 drops out of the second tape conveying section 62 due to the change of the running path and moves to the bottom surface 60a of the tape conveying 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 first 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 second tape transport section 62 that has become vacant due to the change of the running path. The method of inserting the carrier tape 24 into the second tape transport section 62 is the same as the method already described above.

As shown in FIG. 17B, when the carrier tape 24 is detected to be out of components and the passage of the end of the carrier tape 24 is detected by the second sensor PH2, the first tape conveying section 61 moves the carrier tape 24 (tape ejection). 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 second tape transport section 62 transports the next tape 24b waiting at the standby position 23bb. 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 conveyed to a position where it hits the pin of the most upstream sprocket of the first tape conveying portion 61, the carry-in by the carry-in sprocket 62a stops. A change of track is carried out, and the next tape 24b is conveyed as the current tape 24a.

Next, referring to FIGS. 18 to 20, tape replacement processing and component replenishment work support will be described. FIG. 18 is a flow chart showing replacement processing of the carrier tape 24 (tape replacement processing), and FIG. 19 is a flow chart showing support for replenishment of a new carrier tape 24 (component replenishment work support). FIG. 20 is an explanatory diagram for explaining the tape replacement process shown in FIG. 18 and the component supplement work support shown in FIG.

The tape replacement process shown in FIG. 18 is executed while the component mounting apparatus 1 is executing the component mounting process for mounting the component 5 on the substrate 4 . In this example, as shown in state (a) of FIG. 20, reel "A" supplies the current tape 24a and reel "B" supplies the next tape 24b. In the used parts information storage unit 164 of the feeder storage unit 162, the first storage unit 164A stores the parts information related to the current tape 24a with the reel ID "R001" and the parts name "abc", and the second storage unit 164B stores: Part information related to the next tape 24b with reel ID "R002" and part name "abc" is stored.

First, in step S1, the body control unit 17 determines whether or not the current tape ejection condition is satisfied. When the current tape 24a runs out of parts and the second sensor PH2 detects the passage of the end of the current tape 24a (FIG. 17(b)), it is determined that the current tape discharge condition is established. As long as it is determined that the current tape ejection condition is not satisfied (NO in S1), step S1 is repeatedly executed.

In step S2, the body control section 17 causes the first tape conveying section 61 to discharge the current tape 24a. As a result, the state shown in FIG. 17(b) changes to the state shown in FIG. 15(a).

In step S<b>3 , the lower-level updating unit 145</b>B of the first parts information updating unit 145 updates the used parts information storage unit 164 of the feeder storage unit 162 . Specifically, the parts information in the first storage section 164A of the used parts information storage section 164 is cleared. Thereby, the component information regarding the current tape 24a is cleared corresponding to the state (b) of FIG.

In step S<b>4 , the high-level update unit 145</b>A of the first parts information update unit 145 updates the high-level storage unit 104 . Specifically, a component information update notification corresponding to steps S2 and S3 is transmitted to the management device 92 . The parts information update notification includes the reel ID of the current tape 24a ejected in step S2. The management device 92 that has received the parts information update notification sets the number of parts of the reel ID included in the parts information update notification to zero and deletes "current". As a result, the upper storage unit 104 is updated.

In step S5, the body control unit 17 determines whether or not there is the next tape 24b based on the detection result of the carrier tape 24 by the first sensor PH1.

If the first sensor PH1 detects the carrier tape 24 and determines that the next tape 24b is present (YES in S5), the unit control section 64 causes the second tape transport section 62 to move the next tape 24b to the second tape transport section 62 in step S6. 24b is brought in. As a result, the state shown in FIG. 15(a) is sequentially shifted to the state shown in FIG. 15(b), the state shown in FIG. 16(a), and the state shown in FIG. 24a.

In step S<b>7 , the low-level updating unit 145</b>B of the first parts information updating unit 145 updates the used parts information storage unit 164 of the feeder storage unit 162 . Specifically, the parts information in the second storage section 164B is copied to the first storage section 164A of the used parts information storage section 164, and the parts information in the second storage section 164B is cleared. As a result, the component information stored in the second storage unit 164B is moved to the first storage unit 164A, and the component information stored as the next tape 24b in the second storage unit 164B is transferred to the current tape in the first storage unit 164A. It is stored as part information on the tape 24a.

If it is determined in step S5 that there is no next tape 24b (NO in S5), the lower update unit 145B of the first parts information update unit 145 updates the used parts information storage unit 164 of the feeder storage unit 162 in step S8. . Specifically, the parts information in the second storage section 164B of the used parts information storage section 164 is cleared. As a result, if the second storage unit 164B contains the parts information about the next tape 24b, the parts information is cleared.

In step S<b>9 , the high-level update unit 145</b>A of the first parts information update unit 145 updates the high-level storage unit 104 . Specifically, the part information update notification corresponding to steps S5 to S8 is transmitted to the management device 92 . The parts information update notification includes the reel ID of the next tape 24b loaded in step S6 or the reel ID stored in the second storage unit 164B immediately before being cleared in step S8. The management device 92 that has received the parts information update notification changes the tape position column of the reel ID included in the parts information update notification from "next" to "current" when executing step 9 through step S7. At the same time, the remaining number of reels 22 that were "current" is set to 0, and the tape position and feeder address are cleared. When executing step 9 after step S8, if a reel ID is included in the parts information update notification, "next" is deleted from the tape position column of the reel ID, and the reel ID must be included. Skip if

According to the above flow, both the used parts information storage unit 164 of the parts supply unit 23 and the upper storage unit 104 of the management device 92 can be updated according to the discharge of the current tape 24a and the introduction of the next tape 24b. . Specifically, the part information of the ejected current tape 24a is cleared, and the part information of the next tape 24b brought in is updated as a new current tape 24a. Thereby, the component information of the carrier tape 24 can be appropriately managed in the component supply unit 23 .

When the component mounting process of mounting the component 5 on the substrate 4 is performed in the component mounting apparatus 1, the components on the carrier tape 24 are consumed and the product runs out. 24b) must be attached to the component supply unit 23. FIG. The management device 92 identifies the component supply unit 23 to which the next tape 24b is to supply components by referring to the production quantity of mounted boards, the planned production quantity in the production program 106, the remaining quantity in the component management information 108, and the like. , the operator is notified of the specified component supply unit 23 that has an empty second tape conveying unit 62 . Specifically, the portable information terminal 95 carried by the operator displays the name of the component and the feeder address of the component supply unit 23 to which the component is to be supplied. The worker sees the notified information and replenishes the parts.

The component replenishment work support shown in FIG. 19 is a program for assisting the component replenishment work performed by the worker, and is executed by the component replenishment work support unit 102 of the management device 92 . First, in step S11, the parts replenishment work support unit 102 determines whether or not the portable information terminal 95 scans and acquires the parts information of the carrier tape 24 (next tape 24b). That is, it is determined whether or not the operator has caused the portable information terminal 95 to read the bar code 28 of the reel 22 housing the carrier tape 24 for replenishment. Unless the scan information is acquired (NO in S11), step S11 is repeatedly executed. As shown in the state (c) of FIG. 20, when attaching a new reel "C", the worker uses the portable information terminal 95 to read the bar code 28 of the reel "C".

If the scan information has been acquired (YES in S11), it is determined in step S12 whether or not the feeder address has been acquired. Specifically, when the operator presses the operation switch 33 of the component supply unit 23 located at the feeder address displayed on the portable information terminal 95, a signal is output from the component supply unit 23, and the main body control section 17 A feeder address is specified from the signal transmission path, and the feeder address is transmitted to the parts replenishment work support unit 102 of the management device 92 .

If the feeder address is not acquired (NO in S12), it is determined in step S13 whether or not a predetermined time limit has passed. If the time limit is not exceeded (NO in S13), step S12 is executed again. Steps S12 and S13 are repeatedly executed until the feeder address is acquired or the time limit is exceeded. When it is determined that the time limit has passed (YES in S13), in step S14, the scan information acquired in step S11 is cleared, and step S11 is executed again. That is, if the operator leaves the operation switch 33 of the component supply unit 23 unpressed, the operation is restarted from the beginning.

If the feeder address has been acquired (YES in S12), in step S15, it is determined whether or not the verification result is OK, in other words, whether or not the parts replenishment work by the operator is correct. Specifically, it is determined whether or not the correspondence between the part name acquired in step S11 and the feeder address acquired in step S12 and the part name and feeder address registered in the production program 106 match. The support unit 102 determines (parts collation). If the correspondences do not match, it is determined that the matching result is NG (NO in S15), and in step S16, a mismatch notification is given, the scan information acquired in step S11 is cleared, and step S11 is executed again. The mismatch notification is made through the portable information terminal 95 or the feeder display section 34 of the operation panel 18 .

If the correspondences match, it is determined that the matching result is OK (YES in S15), and in step S17, a command to turn on the lamps 36 and 37 in the feeder display section 34 of the component supply unit 23 is transmitted. As a result, the lamp 36 or lamp 37 of the component supply unit 23 to which the new carrier tape 24 should be set is turned on.

In step S18, it is determined whether the insertion of the carrier tape 24 has been detected. When the operator inserts the carrier tape 24 into the component supply unit 23 with the lamp 36 or lamp 37 lit according to a predetermined work procedure, the carrier tape 24 is detected by the first sensor PH1, thereby detecting the insertion of the carrier tape 24. (YES in S18). As shown in state (d) of FIG. 20, the insertion of the carrier tape 24 stored in the reel "C" is detected with the new reel "C" mounted.

If tape insertion is not detected (NO in S18), it is determined in step S19 whether or not a predetermined permission period has elapsed. Steps S18 and S19 are repeatedly executed until tape insertion is detected or the permitted period elapses. If it is determined that the permission period has passed (YES in S19), permission to insert the tape is canceled in step S20, the scanned information is cleared in step S11, and step S11 is executed again. That is, if the worker fails to set the carrier tape 24 to the component supply unit 23 for which the lamp lighting command has been issued within the permitted period, the work is restarted from the beginning.

If the tape insertion is detected within the permitted period (YES in S18), the part information is registered in the second storage unit 164B in step S21. Specifically, the lower level updating unit 145B of the first parts information updating unit 145 updates the parts information included in the scan information acquired in step S11 to the second storage unit 164B of the used parts information storage unit 164 of the feeder storage unit 162. order to register with Upon receiving the command, the second storage unit 164B writes the component information. As shown in the state (d) of FIG. 20, the reel ID "R003" and the part name "abc", which are the part information of the carrier tape 24 stored in the reel "C", are newly stored in the second storage unit 164B. remembered.

In step S<b>22 , the upper updating section 145</b>A of the first component information updating section 145 transmits a component information update notification to the management device 92 . The management device 92, which has received the parts information update notification, updates the parts management information 108 stored in the upper storage unit 104, and puts the state of "next" in the tape position column of the reel ID corresponding to the carrier tape 24 concerned. Along with the addition, add the information of the corresponding address to the field of the feeder address.

According to the flow described above, it is possible to reflect the parts information about the mounted next tape 24b in the feeder storage unit 162 and the parts management information 108 in accordance with the parts replenishment work by mounting a new next tape 24b. Thereby, the component information of the carrier tape 24 used in the component supply unit 23 can be accurately stored. Furthermore, it is possible to prevent the operator from making a mistake in the parts replenishment work.

Next, the remounting process will be described with reference to FIGS. 21 to 23. FIG. FIG. 21 is a flowchart showing a process (remounting process) executed when the component supply unit 23 is remounted on the feeder base 31 . 22A and 22B are diagrams showing an example of a component information input screen displayed on the display panel 95a of the portable information terminal 95 or the touch screen 16a of the operation unit 16 during the remounting process. FIG. 23 is an explanatory diagram for explaining the remounting process shown in FIG. 21. FIG.

If an error occurs in the carrier tape 24 in the component supply unit 23 during component mounting work, the component supply unit 23 may be removed from the component mounting apparatus 1 for recovery work depending on the content of the error. In the restoration work, the carrier tape 24 that has been attached to the component supply unit 23 so far may be removed and replaced with another carrier tape 24. However, the component supply unit 23 removed from the component mounting apparatus 1 is in an off-line state. Therefore, changes in the carrier tape 24 that occur during recovery work are not reflected in the parts management information 108 . Therefore, the carrier tape 24 of the post-restoration component supply unit 23 remounted on the component mounting apparatus 1 does not match the carrier tape 24 stored in the component management information 108, which hinders component inventory management. There was a problem of putting it away. Therefore, in the component mounting system 100, when the component supply unit 23 that has completed the restoration work is remounted on the component mounting apparatus 1, the information on the carrier tape 24 mounted on the component supply unit 23 is acquired to obtain the component management information. 108 (re-mounting process) is provided.

The remounting process shown in FIG. 21 is executed when detachment (remounting) of the component supply unit 23 is detected while the component mounting apparatus 1 is executing the component mounting process for mounting the component 5 on the board 4 . .

State (a) of FIG. 23 shows a scene in which the component supply unit 23 is removed from the component mounting apparatus 1 for restoration work. A current tape 24a supplied from the reel "A" and a next tape 24b supplied from the reel "B" are mounted on the component supply unit 23. As shown in FIG. At this point, the first storage section 164A of the used component information storage section 164 of the component supply unit 23 stores the reel ID "R001" and the component name "R001", which are the component information of the carrier tape 24 supplied from the reel "A". abc" is stored, and the reel ID "R002" and the part name "abc", which are part information of the carrier tape 24 supplied from the reel "B", are stored in the second storage unit 164B.

As shown in state (b) of FIG. 23 , the removed component supply unit 23 is mounted on a workbench 302 independent of the component mounting apparatus 1 . The component supply unit 23 attached to the workbench 302 is connected to the power supply unit 304 (FIG. 3) to be in a power supply state, and various operations using the operation panel 18 can be performed. The component supply unit 23 attached to the workbench 302 is in an “offline state” in which it does not communicate with the component mounting apparatus 1 or the management apparatus 92 . Work performed on the off-line component supply unit 23 cannot be recognized in real time by the component mounting device 1 or the management device 92 . In this example, as shown in the state (b) of FIG. 23, in the off-line state where the component supply unit 23 is mounted on the workbench 302, the current tape 24a and the reel "A" are removed and used as the next tape 24b before recovery. An example will be described in which the current tape 24a is used instead of the carrier tape 24, and the current tape 24a is mounted on the component supply unit 23 and the restoration work is performed.

After the restoration work is completed, the component supply unit 23 with the reel "B" attached is reattached to the feeder base 31 as shown in states (c) and (d) of FIG. The component supply unit 23 reattached to the feeder base 31 returns to the “online state” in which it is communicably connected to the component mounting apparatus 1 . The information stored in the first storage unit 164A and the second storage unit 164B is the same as when it was removed from the component mounting apparatus 1 (state (a) in FIG. 23). It does not match the component information of the carrier tape actually attached to the unit 23 (see reference numeral 164 (1)).

Returning to FIG. 21, when the component supply unit 23 is attached to the component mounting apparatus 1, the reattachment detection section 144 of the main body control section 17 detects reattachment (S31).

When the reattachment detection unit 144 detects reattachment (YES in S31), in step S32, the main body control unit 17 performs reattachment based on the detection results of the first sensor PH1, the second sensor PH2, and the third sensor PH3. The presence or absence of the carrier tape 24 in the component supply unit 23 is confirmed.

In step S33, based on the detection result of the third sensor PH3, the body control section 17 determines whether or not there is the current tape 24a. If the third sensor PH3 does not detect the carrier tape 24, it is determined that there is no current tape (NO in S33), and in step S34, it is determined whether or not the next tape 24b is present based on the detection result of the first sensor PH1. to judge.

When the first sensor PH1 detects the carrier tape 24, it is determined that there is a next tape (YES in S34), and in step S35, the unit control section 64 receives a predetermined signal from the body control section 17 and controls the tape transport. The unit 160 conveys the next tape 24b to the component pickup position 23ba. That is, if there is no current tape 24a (NO at S33) and there is a next tape 24 (YES at S34), the next tape 24b is transported (S35) and changed to the current tape 24a. That is, as shown in FIG. 16(b), the current tape 24a is kept in a state in which it is properly present in the tape transport path 60. FIG.

Next, in step S36, the second component information updating unit 146 of the main body control unit 17 causes the display panel 95a of the portable information terminal 95 or the touch screen 16a of the operation unit 16 to display a component information input screen. Note that, in the present embodiment, the display panel 95a or the touch screen 16a serves as a display section for displaying the component information input screen. This component information input screen is always displayed regardless of whether or not the carrier tape 24 is attached to the reattached component supply unit 23 . An example of the component information input screen will now be described with reference to FIGS. 22A and 22B.

The component information input screen SC1 shown in FIG. 22A includes a scan data display field 201, a current tape information input field 202, a next tape information input field 204, a cancel button 206, and a register button 208.

A scan data display field 201 displays data scanned by the portable information terminal 95, that is, component information of the carrier tape 24. FIG. The scan data display field 201 displays component information such as reel IDs and component names. The current tape information input field 202 is an input field for registering the component information displayed in the scan data display field 201 as the component information of the current tape 24a. The next tape information input field 204 is an input field for registering the component information displayed in the scan data display field 201 as the component information of the next tape 24b. The current tape information input field 202 and the next tape information input field 204 are each configured such that component information displayed in the scan data display field 201 is automatically input by being touched by the operator.

A cancel button 206 is a button for canceling the component information entered in the current tape information input field 202 and the next tape information input field 204 . A registration button 208 is a button for registering the component information entered in the current tape information input field 202 and the next tape information input field 204 .

The current tape information input field 202 and the next tape information input field 204 change between an input enabled state and an input prohibited state depending on the presence or absence of the carrier tape 24 in the remounted component supply unit 23 . The current tape information input field 202 is in an input-enabled state when the third sensor PH3 detects the carrier tape 24, and is in an input-inhibited state when the third sensor PH3 does not detect the carrier tape 24. FIG. Similarly, the next tape information input field 204 is in an input enabled state when the first sensor PH1 detects the carrier tape 24, and is in an input prohibited state when the first sensor PH1 does not detect the carrier tape 24. Become. The component information input screen SC1 shown in FIG. 22B shows an example in which the next tape information input field 204 is in an input prohibited state. The next tape information input field 204 in which input is prohibited is displayed in gray (hatched display).

When the parts information input screen SC1 is displayed on the display panel 95a of the portable information terminal 95 or on the touch screen 16a of the operation unit 16, the operator operates the parts information input screen SC1 while checking the remounted parts supply unit 23. perform an operation for registering the information of the carrier tape 24 attached to the . The second parts information update unit 146 executes processing according to the operator's operation on the parts information input screen SC1 (S37). The operation here includes an operation of inputting component information in the current tape information input field 202 and the next tape information input field 204, a cancel operation using the cancel button 206, and a registration operation using the registration button 208.

An example of the work of registering the information of the carrier tape 24 will be described with reference to the state (d) of FIG. When the component information input screen SC1 is displayed, the operator obtains the component information of the carrier tape 24 attached to the reattached component supply unit 23 . Specifically, the portable information terminal 95 scans the identifier (barcode 28) of the reel "B" to obtain the component information. The second parts information updating unit 146 determines whether the carrier tape 24 attached to the reattached parts supply unit 23 is appropriate based on the parts information read by the portable information terminal 95 . For example, the correspondence between the part name and the feeder address registered in the production program 106 or the part information registered in the used part information storage unit 164 is referred to make the determination. The second parts information update unit 146 notifies the operator by, for example, sounding a buzzer of the portable information terminal 95 if the parts names do not match, and if it is determined to be appropriate, updates the scan data display field of the parts information input screen SC1. 201.

The operator visually confirms the component information displayed in the scan data display field 201 and the carrier tape 24 attached to the component supply unit 23, and taps the current tape information input field 202 if it is the current tape 24a. , the next tape information input field 204 is tapped if it is the next tape 24b. The second part information update unit 146 receives this input operation and inputs the part information displayed in the scan data display field 201 into the current tape information input field 202 or the next tape information input field 204 . In the state (d) of FIG. 23, the input of the next tape information input field 204 is prohibited, so that information that should be registered as part information of the current tape 24a cannot be mistakenly registered as part information of the next tape 24b. ing.

When the operator completes the input operations for all the carrier tapes 24 attached to the component supply unit 23, the operator performs a registration operation by tapping the registration button 208. FIG. The second parts information update unit 146 determines whether or not there has been a registration operation (S38). As long as it is determined that there is no registration operation (NO in S38), steps S37 and S38 are repeatedly executed.

When detecting the registration operation (YES in step S38), the second parts information updating unit 146 updates the used parts information storage unit 164 in step S39. Specifically, the second parts information updating unit 146 causes the parts information to be registered in the first storage unit 164A and/or the second storage unit 164B in the used parts information storage unit 164 of the feeder storage unit 162 . For example, the component information input in the current tape information input field 202 on the component information input screen SC1 is registered in the first storage unit 164A. Also, the component information input in the next tape information input field 204 is registered in the second storage unit 164B. When the input contents of the current tape information input field 202 or the next tape information input field 204 are blank, the corresponding values of the first storage section 164A or the second storage section 164B are cleared. As a result, the used parts information storage unit 164 is updated by the second parts information updating unit 146 .

In the example shown in state (d) of FIG. 23, the information stored in the used parts information storage unit 164 is updated from the content indicated by reference numeral 164(1) to the content indicated by reference numeral 164(2). That is, in the first storage unit 164A, the parts information of reel "A" (reel ID "R001", parts name "abc") is cleared, and the parts information of reel "B" (reel ID "R002", parts name "abc") is cleared. name "abc") is newly registered. Also, the part information (reel ID "R002", part name "abc") of the reel "B" is cleared in the second storage unit 164B. If the contents of the first storage unit 164A before updating and the information input to the current tape information input field 202 are the same, or if the contents of the second storage unit 164B before updating and the information input to the next tape information input field 204 are the same. If the information is the same, the second part information updating unit 146 does not overwrite the first storage unit 164A and the second storage unit 164B with the values of the current tape information input field 202 and the next tape information input field 204, and updates the current tape information. The value of may be maintained.

In step S<b>40 , the second parts information update unit 146 updates the upper storage unit 104 of the management device 92 . Specifically, it transmits to the management device 92 a parts information update notification including the reel IDs entered in the current tape information input field 202 and the next tape information input field 204 . Upon receiving the parts information update notification, the management device 92 updates the contents of the parts management information 108 stored in the upper storage unit 104 based on the registration contents on the parts information input screen SC1. In the example shown in state (d) of FIG. 23, the part information (reel ID "R002", part name "abc") of reel "B" is moved from the second storage unit 164B to the first storage unit 164A, that is, the next tape 24b to the current tape 24a. Therefore, in this example, the reel ID "R002" in the parts management information 108 shown in FIG. 24 is updated from "next" to "current" in the tape position column. Thereby, the parts management information 108 is updated with appropriate contents. Note that information about the carrier tape 24 removed from the component supply unit 23 in the restoration work, such as the reel ID "R001", is updated in the processes after step S41.

In this manner, even if the reel 22 is replaced while the component supply unit 23 is offline, the component information input screen SC1 is displayed on the display panel 95a of the portable information terminal 95 or the operation unit 16 in response to detection of reloading. is displayed on the touch screen 16a and the operator inputs the latest parts information, the parts information in the used parts information storage unit 164 can be updated to match the contents of the actually existing carrier tape 24.例文帳に追加This makes it possible to appropriately manage the correspondence relationship between the component supply unit and the information on the carrier tape.

In step S41, the removal tape confirmation unit 147 determines whether or not there is a removal tape. A removed tape means a carrier tape 24 that may have been removed while the component supply unit 23 was offline. In the example shown in FIG. 23, the carrier tape 24 stored in reel "A" corresponds to the removal tape. Here, a method for determining the presence/absence of the removal tape will be described with reference to FIG. 24 .

FIG. 24 is a diagram showing an example of the parts management information 108 stored in the management device 92. As shown in FIG. In the parts management information 108 shown in FIG. 24, both the carrier tape 24 with the reel ID "R001" (reel "A") and the carrier tape 24 with the reel ID "R002" (reel "B") are stored as the current tape 24a. It is The carrier tape 24 with the reel ID "R002" was newly stored as the current tape 24a by the component information update notification in step S40, whereas the carrier tape 24 with the reel ID "R001" was updated in step S40. It has been stored as the current tape 24a before receiving the notification. Since both the tape position (“current”) and the feeder address (“F012”) overlap, the removed tape confirmation unit 147 determines that the reel ID “R001”, which was in the “current” state before receiving the parts information update notification, ” is determined to be the removal tape.

In step S42, the removed tape confirmation unit 147 causes the display panel 95a of the portable information terminal 95 or the touch screen 16a of the operation unit 16 to display the removed tape inquiry screen RT1. An example of the removed tape inquiry screen RT1 will now be described with reference to FIG.

A removal tape inquiry screen RT1 shown in FIG. 25 is displayed on the display panel 95a of the portable information terminal 95 or the touch screen 16a of the operation unit 16 so as to overlap the parts information input screen SC1. It includes a discard button 210 , a save button 212 and a back button 214 .

The parts information display section 209 is a part that displays the parts information of the carrier tape 24 determined as the removal tape in step S41. In the example shown in FIG. 25, the reel ID, parts name, and remaining number are displayed as parts information. .

A discard button 210, a save button 212, and a return button 214 are all buttons for selecting actions related to the removal tape. The discard button 210 is a button for registering the disposal of the removed tape as "discard", and the storage button 212 is a button for registering the disposal of the removed tape as "storage". The return button 214 is a button for selecting to return to the component information input screen SC1 without registering the removal tape treatment. When the removal tape inquiry screen RT1 is displayed, the operator performs an appropriate operation as a treatment for the carrier tape 24 specified by the parts information displayed on the parts information display section 209. FIG. The removed tape confirmation unit 147 executes processing according to this operator's operation (step 43).

In step S43, the management device 92 executes processing according to the operation on the removed tape inquiry screen RT1. Specifically, according to the button pressed on the removed tape inquiry screen RT1 shown in FIG. . When the pressed button is the discard button 210, as shown in FIG. 26A, for the reel ID "R001", the "remaining number" is set to 0, the "tape position" is cleared, and the feeder address is cleared (shading). display). When the pressed button is the save button 212, as shown in FIG. 26B, the "tape position" is set to "save" and the feeder address is cleared (shaded display). If the pressed button is the return button 214, the removed tape inquiry screen RT1 is simply erased, and the parts management information 108 is not updated.

According to steps S41 to S43, when the component supply unit 23 is in an off-line state in which the component supply unit 23 does not communicate with the component mounting apparatus 1 or the management apparatus 92, the component management is performed so as to reflect the treatment of the carrier tape 24 removed from the component supply unit 23. Information 108 can be updated. As a result, the components can be appropriately managed in carrier tape units (reel units).
