Further, the movable member 62bd is integrally attached to the carry-in sprocket 62a, and when moving in the vertical direction, the carry-in sprocket 62a also moves in the vertical direction. The inner surface of the movable member 62bd is a guide surface that guides the right side surface of the carrier tape 24. The movable member 62bd is moved in the vertical direction (arrow a2 in FIG. 6) by the drive section 62c.

Next, the function of releasing the carrier tape 24 from the tape support portion 62b to the tape transport path 60 will be explained. As shown in FIG. 7A, with the movable member 62bd at the initial position and the second support section 62bb at the same height as the first support section 62ba, the carrier tape 24 is attached to the tape support section 62b. Retained. When releasing the carrier tape 24 from the tape support section 62b, the unit control section 64 drives the drive section 62c to move the movable member 62bd upward. Thereby, it rises together with the second support part 62bb and the carry-in sprocket 62a.

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

As shown in FIG. 7(b), as the movable member 62bd further rises, the twist of the carrier tape 24 increases, and the carrier tape 24 eventually slips off from the first support portion 62ba and the second support portion 62bb.

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

《Shutter unit》
Next, the shutter unit 63 will be explained with reference to FIG. 8. 8 is a side view showing the configuration of the shutter unit. FIG. 8(a) shows a state in which the carrier tape 24 has not reached the shutter unit 63, and FIG. 8(b) shows a state in which the carrier tape 24 has not reached the shutter unit 63. Indicates the state of being stopped.

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

《First tape detection section》
The first tape detection section 63a detects that the carrier tape 24 supported by the tape support section 62b has reached the shutter unit 63 located at the position P1. The first tape detection section 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 part 71a extending opposite to the tape support part 62b, and a contact part 71b extending from the upstream side of the plate-like part 71a toward the tape support part 62b. It has a light shielding part 71c extending from the downstream end of the plate-like part 71a in the opposite direction (upward) to the direction of the tape support part 62b. The tape detection piece 71 is attached to the main body 23d of the component supply device 23 so as to be able to swing around a fulcrum 71d provided near the upstream end. The plate-shaped portion 71a is supported from below by a pin 72 fixed on the downstream side 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 its lower end portion contacts the tip portion of the carrier tape 24 moving along the upper surface of the first support portion 62ba. Located in a contactable position. The position of the contact portion 71b serves as a first checkpoint for detecting the carrier tape 24.

The first sensor PH1 is arranged above the light shielding part 71c. As shown in FIG. 8(b), when the carrier tape 24 moves downstream along the tape support part 62b, the tip of the carrier tape 24 pushes the contact part 71b downstream, and the tape detection piece 71 moves to the fulcrum 71d. Rotate counterclockwise around the center. As a result, the light blocking section 71c blocks the light emitted from the first sensor PH1, and the first sensor PH1 transmits a detection signal to the unit control section 64. Thereby, the first tape detection section 63a can detect that the carrier tape 24 has reached the shutter unit 63 (reached the position P1).

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. The gate unit 63b controls whether the carrier tape 24 supported by the tape support section 62b is allowed to proceed further downstream in the tape transport path 60 or stopped, based on instructions from the unit control section 64.

The gate 74 is, for example, a plate-shaped member, and one end of a compression spring 75 is connected to its upper end.The other end of the compression spring 75 is attached to the main body 23d of the component supply device 23. The gate 74 is urged toward the first support portion 62ba by a compression spring 75. 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 rod, and one end of the locking member 76 is inserted into a recess 74a formed in the side surface of the gate 74 from the lateral direction.

The lever 77 is attached to the main body 23d of the component supply device 23 so as to be able to swing around a fulcrum 77a located in the center. A locking member 76 is fixed to one end (lower end) of the lever 77. The locking member 76 extends laterally toward a recess 74a formed on the side surface of the gate 74. The other end (upper end) of the lever 77 is connected to a rod 78a of an actuator 78. Further, one end of a return spring 79 is connected between the fulcrum 77a 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. The return spring 79 biases the lever 77 in a pulling direction, that is, biases it to rotate clockwise. As a result, the tip of the locking member 76 is inserted into the recess 74a on the side surface of the gate 74 by the return spring 79. When the locking 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 in a locked state. 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 comes off from the recess 74a, allowing the gate 74 to move upward. In other words, the lock is released.

Next, the operation of the shutter unit will be explained with reference to FIGS. 8 to 10. 8 is a side view showing the configuration of the shutter unit, FIG. 9(a) shows a state in which the lock member is unlocked, and FIG. 9(b) shows a state in which the carrier tape 24 passes through the shutter unit 63. shows. FIG. 10 shows a state in which the carrier tape 24 has fallen from the tape support portion 62b.

As shown in FIG. 8(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. 8(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 around the fulcrum 71d. Swings counterclockwise around the central axis. As a result, the light blocking section 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 section 64.

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 recess 74a of the gate 74 hits the locking member 76, preventing the gate 74 from rising. Therefore, the carrier tape 24 cannot enter the tape transport path 60 in the downstream direction due to the gate 74.

Next, when transporting the carrier tape 24 downstream from the gate 74, the unit control section 64 drives the actuator 78 to release the locked state of 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 moves away from the recess 74a of the gate 74, and the gate 74 is unlocked. 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, conveyance of the carrier tape 24 in the downstream direction is started, and as shown in FIG. 9(b), the carrier tape 24 moves toward the downstream side of the tape conveyance path 60 while pushing up the gate 74. Note that the unit control section 64 stops driving the actuator 78 at an appropriate timing after the leading end of the carrier tape 24 passes through the gate 74.

When the carrier tape 24 is conveyed in the downstream direction of the tape conveyance path 60 and conveyed to the third conveyance sprocket 61c, the third sensor PH3 detects the carrier tape 24. The third sensor PH3 transmits a detection signal that detects the carrier tape 24 to the unit control section 64. Upon receiving the detection signal from the third sensor PH3, the unit control section 64 recognizes that the downstream side of the carrier tape 24 is being conveyed to the third conveyance 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 direction of arrow a2. As a result, as shown in FIG. 10 and as already described above, the carrier tape 24 falls from the tape support portion 62b and moves to the bottom surface 60a of the tape transport path 60. When the carrier tape 24 falls from the tape support part 62b, the gate 74 is pressed against the first support part 62ba by the compression spring 75, and the locking member 76 is inserted into the recess 74a of the gate 74 by the return spring. This causes the gate 74 to be in a locked state.

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 retract the rod 78a.

When the carrier tape 24 falls from the tape support portion 62b, the tape detection piece 71 swings clockwise around the fulcrum 71d, and the plate-shaped portion 71a contacts the pin 72, stopping the swinging. As a result, the light shielding section 71c is removed from the first sensor PH1, so that the detection signal is no longer output to the unit control section 64. 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 is not present at the first checkpoint.

《Second tape detection section》
Next, the second tape detection section 111 will be explained with reference to FIG. FIG. 11 is a side view showing the configuration of the second tape detection section 111. FIG. 11(a) shows a state in which the second tape detection unit 111 detects that the carrier tape 24 has not reached position P2, and FIG. 11(b) shows a state in which the carrier tape 24 has not reached position P2. This shows a state in which the second tape detecting section 111 detects that the tape is present.

The second tape detection unit 111 detects whether the carrier tape 24 has reached position P2. The second tape detection section 111 includes a tape detection piece 112, a roller 113, a biasing spring 114, and a second sensor PH2.

The tape detection piece 112 has a substantially T-shape, and includes a plate-like portion 112a extending opposite to the tape conveyance path 60, and a protrusion portion 112b extending toward the tape conveyance path 60 from the upstream side of the plate-like portion 112a. It has a light shielding part 112c extending from the downstream end of the plate-like part 112a in the opposite direction (upward) to the direction of the tape transport path 60. A roller 113 is rotatably attached to the tip of the protrusion 112b.

The tape detection piece 112 is attached to the main body 23d of the component supply device 23 via a biasing spring 114 so as to be able to swing around a fulcrum 112d provided near the upstream end. The biasing spring 114 biases the plate-shaped portion 112a toward the tape transport path 60. The roller 113 is in contact with the tape transport path 60 , and its lower end is located at a position where it can contact the leading end of the carrier tape 24 moving along the transport surface of the tape transport path 60 . The position of the roller 113 is a position P2 for detecting the carrier tape 24.

The second sensor PH2 is arranged above the light shielding part 112c. As shown in FIG. 11(b), when the carrier tape 24 advances toward position P2 along the tape transport path 60, the leading end of the carrier tape 24 pushes up the roller 113, and the tape detection piece 112 moves to the fulcrum 112d. Rotate counterclockwise around the center. Thereby, the light blocking section 112c blocks the light emitted from the second sensor PH2, and the second sensor PH2 transmits a detection signal to the unit control section 64. Thereby, the second tape detection unit 111 can detect that the carrier tape 24 has reached the position P2. Furthermore, in the state shown in FIG. 11(a), the unit control section 64 does not receive the detection signal from the second sensor PH2, so it cannot determine that the carrier tape 24 has not reached the position P2. can.

《Third tape detection section》
Next, the third tape detection section 121 will be explained with reference to FIG. 12. FIG. 12 is a side view showing the configuration of the third tape detection section 121. FIG. 12(a) shows a state in which the carrier tape 24 has not reached position P3, and FIG. 12(b) shows a state in which the carrier tape 24 has reached position P3.

The third tape detection unit 121 detects whether the carrier tape 24 has reached the position P3. The third tape detection section 121 includes a tape detection piece 122, a rod 123, a biasing spring 124, and a third sensor PH3.

The tape detection piece 122 is passed through a through hole 60c provided in a part of the bottom surface 60a or top surface 60b of the tape transport path 60. The tape detection piece 122 is arranged so as to be movable from the outside to the inside of the tape transport path 60. The tip of the tape detection piece 122 is located within the tape transport path 60, and a rod 123 extends from the other end of the tape detection piece 122 on the opposite side to the tape transport path 60. The rod 123 passes through a through hole 125a provided in a wall surface 125 connected to the main body portion 23d, and the tape detection piece 122 and rod 123 are connected to the bottom surface 60a or top surface 60b of the tape transport path 60 and the wall surface 125. Supported. A biasing spring 124 is disposed along and around the rod 123, one end of the biasing spring 124 is connected to the wall surface 125, and the other end is connected to the other end of the tape detection piece 122. The biasing spring 124 biases the tape detection piece 122 toward the tape transport path 60 side. In the tape transport path 60, the position of the tip of the tape detection piece 122 is a position P3.

The third sensor PH3 is arranged on an extension of the rod 123. When the carrier tape 24 moves toward position P3 along the tape transport path 60 from the state shown in FIG. 12(a), the leading edge of the carrier tape 24 touches the tape detection piece 122 as shown in FIG. By pressing downward, the tip of the tape detection piece 122 is pushed into the through hole 60c. As a result, the rod 123 moves downward, the rod 123 blocks the light emitted from the third sensor PH3, and the third sensor PH3 transmits a detection signal to the unit control section 64. Thereby, the third tape detection unit 121 can detect that the carrier tape 24 has reached the position P3. Furthermore, in the state shown in FIG. 12(a), the unit control section 64 does not receive the detection signal from the third sensor PH3, so it is difficult to determine that the carrier tape 24 has not reached the position P3. can.

《4th sensor》
See FIG. 6. The fourth sensor PH4 is a photoelectric sensor that detects whether the carrier tape 24 has reached the position P4. The fourth sensor PH4 is, for example, a reflective or transmissive color sensor. The fourth sensor PH4 can also detect the connecting tape 24c that connects the current tape and the next tape. Details will be explained later.

Next, the exposed portion 66 will be explained with reference to FIG. 13. FIG. 13 is a side view showing the configuration of the exposed portion 66. 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 returned past the exposed portion 66. Note that in this specification, "forward" of the carrier tape 24 means that the carrier tape 24 is transported in the downstream direction, and "reverse movement" of the carrier tape 24 means that the carrier tape 24 is transported in the upstream direction. means.

An exposed portion 66 is arranged on an inclined portion of the tape transport path 60, diagonally below the upstream side of the component take-out position 23ba. The exposed portion 66 peels off the top tape 52 of the carrier tape 24 from the base tape 51 to expose the upper surface of the component 5 housed 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 that drives these

rollers

81 and 82. The drive mechanism of the exposed portion 66 includes a motor as a drive source and a drive transmission mechanism such as a gear that transmits the rotational power of the motor to the

rollers

81 and 82. The drive mechanism of the exposed portion 66 is controlled by the unit control section 64 to rotate, and the roller 81 is rotated, thereby performing the peeling operation of the top tape 52, which will be described below.

The extended portion 52a of the top tape 52 of the carrier tape 24 conveyed from the upstream side along the tape conveyance path 60 is drawn into the

rollers

81 and 82 through the opening 83 and peeled off from the base tape 51. The newly set carrier tape 24 is fed from the tape input port 2a of the tape transport path 60 with the top tape 52 having a tip 52b longer than the base tape 51 (having an extension 52a). When the leading end of the carrier tape 24 reaches the opening 83, the extending portion 52a 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 peeled off from the base tape 51 of the carrier tape 24. In the following description, after the top tape 52 is peeled off from the base tape 51, the base tape 51 from which the top tape 52 has been peeled off will also be referred to as a carrier tape 24.

The third sensor PH3 of the third tape detection section 121 is arranged downstream of the position where the exposed portion 66 is arranged. Instead of the configuration of the third tape detection unit 121 described above, for example, the third sensor PH3, which is a transmission detection type optical sensor, may be used to detect the carrier tape 24 conveyed along the tape conveyance path 60. good. The detection result by the third sensor PH3 is sent to the unit control section 64. Note that, like the configuration of the third tape detection unit 121 described above, a dog that can mechanically contact the tip of the carrier tape 24 is provided, and an optical sensor detects the displacement of the dog that occurs when the carrier tape 24 comes into contact with the dog. The leading end of the carrier tape 24 may be detected by detecting the tip. 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-transmitting material.

On the bottom surface 60a side of the tape transport path 60, an air nozzle 84 that injects air is arranged at a position facing the opening 83, with the air injection direction facing the opening 83. The air nozzle 84 is an injection part that injects air, and the ejected air is applied to the extending part 52a of the top tape 52 located near the opening 83, and the extended part 52a of the top tape 52 is blown out by the force of the ejected air. 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. Air is supplied to the air nozzle 84 from an air supply section (not shown).

By controlling the opening and closing of the control valve 70 (FIG. 15) connected to the air supply section by the unit control section 64, air can be injected from the air nozzle 84 toward the exposed section 66 at any timing. In this embodiment, the unit control section 64 injects air from the air nozzle 84 at the timing when the top tape 52 is corrected and the extension section 52a reaches a position where it can be captured by the exposed section 66. It's in control. For example, when the third sensor PH3 detects the leading edge of the carrier tape 24 as shown in FIG. 13(a), the third conveying sprocket 61c moves the carrier tape 24 a predetermined distance or for a predetermined time as shown in FIG. 13(b). The air may be injected after the air is sent in the upstream direction. While the carrier tape 24 is moved in the opposite direction for a predetermined distance or a predetermined time, the curling of the top tape 52 is corrected, and the extending portion 52a is moved below the opening 83.

By blowing the air ejected from the air nozzle 84 onto 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. 14(a), and the extending portion 52a pressed against the roller 81 is captured by being sandwiched between one roller 81 and the other roller 82. Then, the top tape 52 is peeled off from the base tape 51 by continuing to rotate the

rollers

81 and 82 to draw the top tape 52 in a direction away from the base tape 51.

In FIG. 6, the unit control section 64 is communicably connected to the drive section 61d, the exposed section 66, and the third sensor PH3 of the third tape detection section 121. 66. That is, the unit control section 64 controls the third conveyance sprocket 61c to perform a tape conveyance operation of conveying the carrier tape 24 along the tape conveyance path 60. At this time, the unit control section 64 can control the timing and amount of transport of the carrier tape 24.

Furthermore, 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 to peel 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 jetting 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 further communicatively connected to the main body section 2 of the component mounting apparatus 1. The above-described tape conveyance operation and tape feeding operation are executed by operation commands input from the operation section and control commands transmitted from the main body section 2.

Next, the functional configuration of the component supply device 23 will be described with reference to FIG. 15. FIG. 15 is a block diagram showing an example of the functional configuration of the component supply device 23. As shown in FIG.

A plurality of component supply devices 23 can be mounted on the component mounting device 1, and each of the component supply devices 23 is provided with a unit control section 64. The unit control section 64 includes a tape transport control section 64a, a sensor check section 64b, a display processing section 64c, and a storage section 64d. The unit control section 64 can be realized by a circuit made up of a semiconductor element or the like. The unit control section 64 can be configured with a circuit such as a microcomputer, CPU, MPU, GPU, DSP, FPGA, or ASIC, for example. The functions of the unit control section 64 may be configured only by hardware, or may be realized by a combination of hardware and software. The unit control section 64 realizes predetermined functions by reading data and programs stored in the storage section 64d and performing various arithmetic processing.

The unit control section 64 is electrically connected to the switches 33a to 33e of the operation section 33, the 7-segment display 35, and the

lamps

36 and 37 of the feeder display section 34, and controls the operation of each component. Further, the unit control section 64 is electrically connected to the first sensor PH1, the second sensor PH2, the third sensor PH3, the fourth sensor PH4, the drive section 61d, the drive section 62c, the actuator 78, and the control valve 70. and controls the operation of each component.

The tape conveyance control section 64a controls the feeding operation of the carrier tape 24 mounted on the component supply device 23 based on commands from the main body control section 17.

When the sensor check unit 64b receives the detection signals from the first sensor PH1 to the fourth sensor PH4, it determines that each of the received tape detection units and sensors is normal, and sends the determination result to the display processing unit 64c.

The display processing section 64c shows the inspection results on the display corresponding to each tape detection section and sensor according to the determination result of the sensor check section 64b. For example, the display processing unit 64c lights up the corresponding segment of the 7-segment display 35 of the feeder display unit 34 if the first sensor PH1 to the fourth sensor PH4 are normal, and if it is abnormal, the corresponding segment of the 7-segment display 35 lights up. Keep the corresponding segment unlit.

The storage unit 64d stores component information of the carrier tape 24 mounted on the component supply device 23. The storage unit 64d stores component information of the current tape 24a and the next tape 24b that are attached to the component supply device 23.

The unit side connector 65 is communicably connected to the main body side connector 10 via the connector of the feeder base 31, and information can be mutually transmitted and received between the unit control section 64 and the main body control section 17. can. Note that the unit side connector 65 is connected to a connector of an external setup device or a maintenance device when the component supply device 23 is removed from the main body 2, and is connected between the unit control section 64 and the external setup device, maintenance device, etc. Information may be exchanged between them.

The main body control section 17 controls the work of mounting components on the main body section 2. The inspection results of the first tape detection section 63a, second tape detection section 111, third tape detection section 121, and fourth sensor PH4 are sent from the sensor check section 64b of the component supply device 23 to the main body control section 17, and displayed on the touch screen 16a. These test results may be displayed.

Next, the carrier tape conveyance operation by the component supply device 23 will be described with reference to FIGS. 16 to 18.

Refer to FIG. 16(a). The operator inserts the carrier tape 24 along the tape support portion 62b arranged at the tape inlet 23a of the component supply device 23 where the lamps 36 and 37 (FIG. 5) of the operation panel 18 are flashing. After inserting the carrier tape 24, the operator presses the switch 33d (FIG. 5) of the component supply device 23. When the current tape 24a is on the downstream side of the tape transport path 60, the second tape transport section 62 transports the carrier tape 24 while the gate 74 of the gate unit 63b is locked, and the first sensor PH1 carries out the carrier tape 24. When 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 transport section 62 will not operate. In either case, the carrier tape 24 cannot enter deeper than the gate 74. In this way, the carrier tape 24 waits at a standby position 23bb located upstream of a component removal 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 switch 33d, the gate 74 is unlocked when the switch 33d is pressed, and in this state the second tape transport section 62 transports 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. 16(b), when the carrier tape 24 is transported to a position where it hits the pin of the third transport sprocket 61c, the transport by the transport sprocket 62a stops. The carrier tape 24 is further transported downstream by the third transport sprocket 61c, and when detected by the third sensor PH3, the first tape transport section 61 performs an operation to cause the exposed portion 66 to capture the top tape 52.

When the exposed part 66 captures the top tape 52, the exposed part 66 and the third transport sprocket 61c transport the carrier tape 24 further downstream while peeling off the top tape 52. When the pin of the second conveyance sprocket 61b is inserted into the feed hole 54 of the carrier tape 24, as shown in FIG. The pocket 53 is positioned at the component removal position 23ba. An opening is formed at a position corresponding to the component removal position 23ba.

Next, the running path is changed in the second tape transport section 62. As shown in FIG. 17(b), the carrier tape 24 passing through the second tape transport section 62 drops from the second tape transport section 62 due to the path change and moves to the bottom surface 60a of the tape transport path 60 below. Note that the travel path change is executed at a timing when the carrier tape 24 is engaged with the second conveyance sprocket 61b and the third conveyance sprocket 61c of the first tape conveyance section 61. Furthermore, when the route change is executed, the gate 74 moves downward and becomes locked.

As shown in FIG. 18(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 in the running route. The method for 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. 18(b), when it is detected that the carrier tape 24 is out of parts and the passage of the end of the carrier tape 24 is detected by the second sensor PH2, the first tape transport section 61 moves the carrier tape 24 (tape ejection). If the passage of the terminal end of the carrier tape 24 is not detected at the time when component shortage is detected, a terminal end search is performed, and then the tape is discharged. When the current tape 24a has been unloaded, the gate 74 is unlocked, and in this state, the second tape transport section 62 transports the next tape 24b that has been waiting at the standby position 23bb. As a result, the next tape 24b pushes up the gate 74 with its leading end and is sent into the tape transport path 60. When the next tape 24b is conveyed to the position where it hits the pin of the most upstream sprocket of the first tape conveyance section 61, the conveyance by the conveyance sprocket 62a is stopped. The running route is changed, and the next tape 24b is transported as the current tape 24a.

"Inspection method"
Next, with reference to FIGS. 5, 19, 20, and 21, a method for testing the first tape detection section 63a, second tape detection section 111, third tape detection section 121, and fourth sensor PH4 will be explained. do. FIG. 19 is a diagram illustrating insertion of the jig tape 131 into the component supply device 23. FIGS. 20 and 21 are diagrams for explaining the progress of the jig tape and the display of detection results. FIG. 20(a) shows the display state of the 7-segment display when the leading end of the jig tape 131 reaches position P1, and FIG. 20(b) shows the display state when the leading end of the jig tape 131 reaches position P2. This shows the display status of the 7-segment display. FIG. 21(a) shows the display state of the 7-segment display when the tip of the jig tape 131 reaches position P3, and FIG. 21(b) shows the display state of the 7-segment display when the tip of the jig tape 131 reaches position P4. This shows the display status of the 7-segment display.

The feeder display section 34 has a normal mode that displays the control state of the component supply device 23, and a detection mode of each of the first tape detection section 63a, the second tape detection section 111, the third tape detection section 121, and the fourth sensor PH4. It has an inspection mode that displays the results. By pressing the switch 33a of the operation section 33, the display processing section 64c of the unit control section 64 performs a display according to each mode on the feeder display section 34.

In the normal mode, the display processing unit 64c displays the error number and symbol on the 7-segment display 35, and displays or flashes the

lamps

36 and 37 to inform the operator of the control status of the corresponding component supply device 23. inform.

The 7-segment display 35 includes a first 7-segment display 35a and a second 7-segment display 35b. The first 7-segment display 35a has seven display segments, segments 171-177. The second seven segment display 35b also has seven display segments, segments 181-187. Each segment has a built-in light emitting diode (LED), and its lighting and extinguishing are controlled by the display processing unit 64c.

In the inspection mode, the display processing unit 64c displays the detection results of the first sensor PH1, the second sensor PH2, the third sensor PH3, and the fourth sensor PH4 on the corresponding 7-segment display 35, so that the operator can It is reported whether or not the first tape detection section 63a, the second tape detection section 111, the third tape detection section 121, and the fourth sensor PH4 are operating normally. At this time, inspection accuracy can be further improved by inserting the inspection jig tape 131 into the component supply device 23 for inspection.

Furthermore, in the inspection mode, the display processing section 64c performs a corresponding display on the feeder display section 34 in order to notify the operator that the component supply device 23 is executing the inspection mode. For example, the display processing unit 64c lights the lamp 36 or the lamp 37 in yellow in the inspection mode, and lights in green in the normal mode.

In the inspection mode, when the operator inserts the jig tape 131 into the tape inlet 23a of the component supply device 23 and presses the switch 33b to sequentially feed the jig tape 131, the jig tape 131 is inserted as shown in FIG. The leading end of the tape 131 reaches position P1, and the first tape detection section 63a detects the jig tape 131. When the first tape detection section 63a detects the jig tape 131, a detection signal is sent from the first sensor PH1 to the unit control section 64, and the sensor check section 64b determines that the first tape detection section 63a is normal. , causes the display processing unit 64c to light up the segment 172 of the first 7-segment display 35a. The segment 172 is a display adapted to notify whether or not the first tape detection section 63a is normal. Thereby, the operator can know both that the jig tape 131 has reached the position P1 and that the first tape detection section 63a is normal.

Next, when the operator presses the switch 33b to further feed the jig tape 131, the leading end of the jig tape 131 reaches position P2, and the second tape detector 111 detects the jig tape 131. When the second tape detection section 111 detects the jig tape 131, a detection signal is sent from the second sensor PH2 to the unit control section 64, and the sensor check section 64b determines that the second tape detection section 111 is normal. , causes the display processing unit 64c to light up the segment 173 of the first 7-segment display 35a. The segment 173 is a display adapted to notify whether or not the second tape detection section 111 is normal. Thereby, the operator can know both that the jig tape 131 has reached the position P2 and that the second tape detection section 111 is normal.

Next, when the operator presses the switch 33b to further feed the jig tape 131, the leading end of the jig tape 131 reaches position P3 and the fourth sensor PH4 is activated, as shown in FIG. 21(a). The jig tape 131 is detected. When the fourth sensor PH4 detects the jig tape 131, it sends a detection signal to the unit control section 64, and the sensor check section 64b determines that the fourth sensor PH4 is normal and sends the second seven segments to the display processing section 64c. Segment 182 of display 35b is lit. The segment 182 is a display adapted to notify whether the fourth sensor PH4 is normal or not. Thereby, the operator can know both that the jig tape 131 has reached the position P3 and that the fourth sensor PH4 is normal.

Next, when the operator presses the switch 33b to further sequentially feed the jig tape 131, the leading end of the jig tape 131 reaches position P4, and the third tape detector 121 detects the jig tape 131. When the third tape detection section 121 detects the jig tape 131, a detection signal is sent from the third sensor PH3 to the unit control section 64, and the sensor check section 64b determines that the third tape detection section 121 is normal. , causes the display processing unit 64c to light up the segment 183 of the second 7-segment display 35b. The segment 183 is a display adapted to notify whether or not the third tape detection section 121 is normal. Thereby, the operator can know both that the jig tape 131 has reached the position P4 and that the third tape detection section 121 is normal.

In the test mode, the test results are displayed until the switch 33a is pressed to return to the normal mode. Therefore, as shown in FIG. 21(b), when the operator confirms that the four segments of the seven-segment display 35 indicating the detection results of each tape detection section and the fourth sensor PH4 are lit, It can be confirmed that each tape detection section and the fourth sensor PH4 are operating normally.

For example, as shown in FIG. 22, when the segment 173 is off and the

segments

172, 182, and 183 are on, the operator can detect that the second tape detection section 111 is in an abnormal state and the first tape detection section 63a, It can be known that the fourth sensor PH4 and the third tape detection section 121 are normal.

The inspection mode is also effective when the carrier tape 24 stops in the middle of the tape transport path 60 when inserting the leading end of the carrier tape 24 into the tape transport path 60 in the normal mode. In this case, by shifting from the normal mode to the inspection mode, the operator can know how far the leading edge of the carrier tape 24 has been conveyed between positions P1 to P4, and where the leading edge of the carrier tape 24 is jammed. You can find out if there are any.

Next, the supply of the carrier tape 24 in the case where the component supply device 23A is a splicing feeder will be described with reference to FIGS. 23 to 25. FIG. 23 is a side view showing a state in which the carrier tape 24 in which the next tape 24b is connected to the current tape 24a is sent to the component supply device 23A. 24 and 25 are perspective views illustrating the connection between the current tape 24a and the next tape 24b.

As shown in FIG. 23, the loading unit 23db may be removed from the core unit 23da of the component supply device 23, and the carrier tape 24 may be supplied to the component supply device 23A as a splicing feeder.

By connecting the leading end of the next tape 24b to the end of the current tape 24a using the connecting tape 24c, the operator can continuously feed the carrier tape 24 to the component supply device 23A without interrupting the supply. can.

A method for connecting the current tape 24a and the next tape 24b will be illustrated. As shown in FIG. 24(a), the end of the current tape 24a and the tip of the next tape 24b are arranged in the longitudinal direction so that the tape widths match, and as shown in FIG. 24(b), the end of the current tape 24a A connecting tape 24c is attached to the lower surface of the end of the next tape 24b and the tip of the next tape 24b.

Next, as shown in FIG. 25(a), a connecting tape 24c is wrapped around each side of the end of the current tape 24a and the tip of the next tape 24b, and further, as shown in FIG. 25(a), , a connecting tape 24c is attached to the upper surface of the end of the current tape 24a and the tip of the next tape 24b. Note that the current tape 24a and the next tape 24b are colorless, but the connecting tape 24c is colored.

Next, the inspection jig tape 131 will be explained with reference to FIG. 26. 26(a) is a plan view of the jig tape 131, and FIG. 26(b) is a partially enlarged view of the jig tape 131.

The jig tape 131 has a tape portion 131a and a stopper portion 131b. The tape portion 131a is a portion inserted into the tape transport path 60, and the stopper portion 131b has a width W1 that does not allow insertion into the tape entrance 23a. can be prevented from being inserted into the

The tape portion 131a has a feed hole 133, a colored portion 135, and an engagement avoidance portion 137. The feed hole 133 engages with each pin of the second conveyance sprocket 61b and the third conveyance sprocket 61c. A plurality of feed holes 133 are arranged in a line along the longitudinal direction of the tape portion 131a.

As shown in FIG. 27, the engagement avoidance part 137 avoids engagement with the pin of the first conveyance sprocket 61a when the loading unit of the component supply device 23 is not removed and is used as a splicing feeder, so the jig tape The stopper portion 131b of 131 can be prevented from being carried into the tape entrance 23a. The engagement avoidance portion 137 has a long hole shape, but may alternatively be a notch.

Refer to FIG. 26. The colored portion 135 is a region that is colored differently from other portions of the tape portion 131a. Since the tape portion 131a is made of resin like the carrier tape 24, the color of the resin is, for example, milky white or colorless, but the region of the colored portion 135 is colored, for example, blue. The position of the colored portion 135 is a portion where, when the tape portion 131a is inserted into the tape transport path 60, the colored portion 135 reaches the position P4 where the fourth sensor PH4 is arranged. Therefore, the length L1 from the engagement avoidance part 137 to the colored part 135 is longer than the length from the tape entrance 23a to the position P3 in the tape transport path 60.

The physical state of the jig tape 131 differs between the colored portion 135 area and other areas. This difference in physical state is a color in this embodiment, but may be of other properties. For example, the fourth sensor PH4 may be configured as a metal sensor and a magnetic sensor by pasting a metal sheet or magnetic tape in the area of the colored portion 135 to detect differences in the physical state of the jig tape 131. . It is only necessary that the connecting tape 24c that connects the current tape 24a and the next tape 24b and the colored portion 135 have the same physical state.

Refer to FIG. 27. FIG. 27 is a diagram illustrating the progress of the jig tape 131 and the display of detection results. As in FIG. 21(b), since the

segments

172, 173, 182, and 183 are lit, each tape detection section and the fourth sensor PH4 detect the arrival of the jig tape 131, and each is in a normal state. It is informing you of something.

Further, since the segment 185 is lit, the fourth sensor PH4 detects the difference in color of the colored portion 135, and notifies that the color sensor of the fourth sensor PH4 is normal. Thereby, the operator can confirm that the fourth sensor PH4 can normally detect the connecting tape 24c.

Note that the display processing unit 64c may notify that the component supply device 23 is in the inspection mode by lighting a segment of the 7-segment display 35 instead of lighting the lamp 36 or the lamp 37. In FIG. 27, the display processing unit 64c notifies the operator of the inspection mode by lighting up the segment 177 of the 7-segment display 35. In normal mode, segment 177 is off.

As described above, according to the component supply device 23 of the present embodiment, there is a tape conveyance path 60 through which the carrier tape 24 containing the components 5 passes, and a first tape conveyance path through which the carrier tape 24 is conveyed along the tape conveyance path 60. 61, a third tape detection section 121 that detects whether the carrier tape 24 is present at position P4 of the tape conveyance path 60, and a third tape detection section 121 that detects whether the carrier tape 24 is present at position P3 of the tape conveyance path 60. A fourth sensor PH4 for detection is provided. The first tape transport section 61 transports a tape-shaped jig tape 131 having a length that allows it to reach positions P4 and P3 from the tape entrance 23a of the tape transport path 60 along the tape transport path 60. The third tape detection unit 121 outputs a detection result indicating whether the jig tape 131 has reached the position P4. The fourth sensor PH4 outputs a detection result indicating whether the jig tape 131 has reached the position P3.

As a result, even though the jig tape 131 has reached the positions P4 and P3, the third tape detection unit 121 or the fourth sensor PH4 is not outputting a detection result indicating that the jig tape 131 has reached the positions P4 and P3, respectively. In this case, the operator can easily determine that the third tape detection section 121 or the fourth sensor PH4, which is not outputting a detection result, is abnormal. Further, without connecting the component supply device 23 to a dedicated inspection device, the component supply device 23 alone can test whether the third tape detection section 121 and the fourth sensor PH4 are normal. In this way, it is possible to provide the component supply device 23 that can easily test whether the third tape detection unit 121 that detects the carrier tape 24 and the fourth sensor PH4 are normal.

The feeder display unit 34 also includes a feeder display unit 34 that notifies the detection results of the third tape detection unit 121 and the fourth sensor PH4, and the feeder display unit 34 displays the detection results of the third tape detection unit 121 and the fourth sensor PH4. will be notified separately.

Furthermore, the feeder display section 34 includes a segment 183 that displays the detection result of the third tape detection section 121, and a segment 182 that displays the detection result of the fourth sensor PH4.

Further, the detection results of the third tape detection unit 121 and the fourth sensor PH4 are displayed on the touch screen 16a of the main body 2, the display panel 95a of the portable information terminal 95, which is a device external to the component supply device 23, or Output to the management device 92. As a result, the detection results of the third tape detection unit 121 and the fourth sensor PH4 can be shared with devices outside the component supply device 23, and even workers who are away from the component supply device 23 can know the detection results. be able to.

Furthermore, the jig tape 131 is tape-shaped and has a length that reaches positions P4 and P3, and the physical state is different between the portion of the colored portion 135 that reaches position P3 and the other portions. By using this jig tape 131, it is possible to easily test whether the fourth sensor PH4 of the component supply device 23 normally detects parts of the colored portion 135 that have different physical states.
