Subsequently, the suction pad 621 is raised to the carrier tape winder 200 by the Z-axis linear actuator 623. Subsequently, the suction pad 621 advances to the carrier tape winder 200 and returns after attaching the barcode 601 to the empty reel 101.

An example of the operation of the above-described automatic reel replacement system 1000 will be described as follows.

The empty reels 101 are loaded on the empty reel stacker 100 and wait. At this time, the empty reel 101 of the lowermost layer loaded on the empty reel stacker 100 is supported by the shutter 120 so as not to be withdrawn from the reel outlet 110a and waits. In this state, the reel changer 400 withdraws the lowermost empty reel 101 from the empty reel stacker 100 and supplies it to the carrier tape winder 200.

At this time, the changer grippers 420 are positioned up and down in the standby area and start to rise by the Z-axis linear actuator 460 while facing the reel outlet 110a. While the upper changer gripper 420 continues to rise, the lowermost empty reel 101 is adsorbed through the reel outlet 110a, and then rises further to the top dead center. Then, the shutter 120 opens the reel outlet 110a, and accordingly, the upper change gripper 420 pulls the lowermost empty reel 101 out of the reel outlet 110a.

Subsequently, the shutter 120 closes the reel outlet 110a again to support the trailing blank reel 101, thereby blocking withdrawal of the trailing blank reel 101. The changer gripper 420 adsorbing the empty reel 101 descends to the bottom dead center and then rotates 90 degrees by the Y-axis rotation actuator 440 so as to face the winder gripper 211. The changer gripper 420 adsorbing the empty reel 101 advances to the winder gripper 211 by the X-axis linear actuator 450 to bring the empty reel 101 into contact with the winder gripper 211. Then, the winder gripper 211 adsorbs the empty reel 101, and accordingly, the changer gripper 420 separates the empty reel 101.

Subsequently, the changer gripper 420 is retracted from the winder gripper 211 to the standby area, and then is positioned on the upper side and rotates 90 degrees to face the reel outlet 110a. At this time, the barcode transfer 620 adsorbs the bar code 601 issued from the bar code printer 610 to the adsorption pad 621, and then attaches the adsorption pad 621 to which the bar code 601 is adsorbed to the winder gripper 211. It can be moved to and attached to the empty reel 101 of the gripper 211 for the winder.

At this time, the adhesive tape presser 240 is attached by pressing the adhesive tape 230a along the rear end of the carrier tape 10 and the winding portion of the carrier tape 10. Accordingly, the carrier tape 10 may be fixed while being wound around the reel 101.

While the winder gripper 211 winds the carrier tape 10, the empty changer gripper 420 is turned to face the winder gripper 211 and waits. When the carrier tape 10 is wound and fixed to the reel 101 by the above-described process, the winder gripper 211 descends to the bottom dead center. Then, the empty changer gripper 420 advances to the winder gripper 211, receives the reel 101 from the winder gripper 211, and returns to the standby area.

Subsequently, the change gripper 420 adsorbing the empty reel 101 is turned 180 degrees to face the winder gripper 211, and then the empty reel 101 is transferred to the winder gripper 211, and the standby area Return to Then, the barcode 601 is attached to the empty reel 101 of the winder gripper 211 as described above. Subsequently, the carrier tape 10 is wound and fixed on the empty reel 101 of the winder gripper 211 as described above. At the same time, the gripper 420 for a changer adsorbing the reel 101 on which the carrier tape 10 is wound and fixed rises to the top dead center.

Then, the banding machine 300 bends the carrier tape 10 fixed by being wound on the reel 101 by the carrier tape winder 200 with a band 301.

It is supplied between the outer surface of the tape 10 and the adhesive tape 330a. Then, the changer gripper 420 starts winding the band 301 as it rotates by the gripper rotation actuator 430. At this time, the adhesive tape pressurizer 340 presses and attaches the adhesive tape 330a along the outer surface of the carrier tape 10 and the tip of the band 301.

When the changer gripper 420 continues to rotate and winds the band 301 by a set length, the adhesive tape 330a is supplied from the adhesive tape feeder 330 to the rear end of the band 301. At this time, the adhesive tape pressurizer 340 is attached by pressing the adhesive tape 330a along the rear end of the band 301 and the winding portion of the band 301. Accordingly, the band 301 may be fixed while wrapping the outer circumference of the carrier tape 10 wound around the reel 101. Then, the changer gripper 420 adsorbing the bent reel 101 descends to the bottom dead center and then turns to face the take-out table 510 of the take-out stacker 500. Then, the carry-out table 510 rises by the Z-axis linear actuator 521 and comes into contact with the reel 101 of the changer gripper 420. Then, the changer gripper 420 separates the reel 101 and transfers it to the carrying table 510. Then, the carry-out table 510 descends and returns by the Z-axis linear actuator 521. Then, the changer gripper 420 returns to the standby area and waits by withdrawing the trailing empty reel 101 from the empty reel stacker 100 as described above.
