Thereafter, the third moving actuator 630 moves the lid holding part 610 toward the discharge hopper 650, opens the third holding members 612 to release the support for the cap 101, and the third lifting actuator 620 and the third moving actuator 630 is returned to the initial position to grip the cap 101 again.

As the turntable 200 rotates, the support member 201 continuously equipped with the cap 101 is positioned below the lid grip 610, and the withdrawal unit 600 continues while repeating the above operations. The cap 101 with the rubber packing 102 is withdrawn to the discharge hopper 650.

On the other hand, the blood vessel cap assembly apparatus 100 according to the present invention is installed adjacent to the extraction unit 600 in the rotational direction of the turntable 200 is the support member 201 by the extraction unit 600 If the cap 101 is detected in the support member 201 through the failure detection sensor unit 710 and the failure detection sensor unit 710 to determine whether the cap 101 is present in the The control unit 720 to stop the operation of the turntable 200, and the operation is controlled by the control unit 720, and sends a warning signal to the manager when the cap 101 is detected through the failure detection sensor unit 710 It further comprises a warning device 730.

The failure detection sensor unit 710 is for stopping the rotation of the turntable 200 when the cap 101 is not drawn out from the support member 201 due to a malfunction of the drawing unit 600 or other problems. Cap support provided on the third support frame 711 installed in the adjacent position of the withdrawal unit 600 and the third support frame 711 at the position opposite to the upper surface of the support member 201 along the rotation direction of the 200 Sensor 712 is provided.

Although not shown in the drawing, the cap detecting sensor 712 transmits the ultrasonic waves to the supporting member 201 and receives the ultrasonic waves reflected by the supporting member 201 to measure the time for which the ultrasonic waves are returned to the supporting member 201. Detects the presence of the cap 101.

The controller 720 determines that the cap 101 is present in the support member 201 when the time from which the ultrasonic wave is emitted from the cap detection sensor 712 to the support member 201 is shorter than a preset reference time. The rotation of the turntable 200 is stopped through, and a failure occurrence signal is sent to the warning device 730.

 The warning device unit 730 outputs a warning sound to the manager when receiving the bad occurrence signal from the control unit 720. When the alarm sounds from the warning device 730, the manager removes the cap 101 seated on the support member 201, resumes the operation of the drive unit 202 to rotate the turntable 200.

The failure detection sensor unit 710 has been described a structure for detecting the cap 101 through the ultrasonic wave, but is not limited to the above embodiment, if the detection means for detecting the cap 101 on the support member 201 It is possible.

The blood vessel lid assembly apparatus 100 according to the present invention configured as described above automatically lowers the manufacturing cost by inserting the rubber packing 102 into the cap 101 and eliminates assembly defects of the lid to improve the quality of the final product. Can be improved.
