Accordingly, the detachable protrusion 153b that is elastically elastically supported on the outer circumferential surface of the connecting protrusion 151a is inserted into the detachable groove 151b.

As described above, the detachment protrusion 153b is seated in the detachable groove 151b, and the labeling unit is mounted on the rotational end of the robot as the connection protrusion 151a is seated in the connection groove 153a.

8 and 9 illustrate a labeling operation of the coil packaging labeling apparatus according to the present embodiment.

10 and 11, the robot 130 transfers the labeling unit 110 to the label 20 side in which one surface is exposed. As the labeling unit 110 is transferred to the label 20 side, one surface of the suction plate 115a is close to one surface of the label 20. In this case, the first detector 117a detects the contact between the adsorption plate 115a and the label 20 by sensing the gap between the adsorption plate 115a and the label 20.

When the contact between the suction plate 115a and the label 20 is detected by the first detector 117a, vacuum evacuation of the suction flow path 115a ′ is performed through the vacuum port 115b. As the vacuum exhaust of the suction flow path 115a 'is performed, the label 20 is peeled from the release paper 21 so that one surface thereof is suction-supported on one surface of the suction plate 115a.

As such, the label 20 is supported by the labeling unit 110 with one surface adsorbed on one surface of the adsorption plate 115a and the back surface on which the adhesive is applied is exposed.

Subsequently, the robot 130 transfers the labeling unit 110 to the coil 10 side. In this case, the second detector 117b detects a gap between the suction plate 115a and the coil 10. When the gap between the suction plate 115a and the label 20 is detected by the second detector 117b, the robot 130 slows down the transfer speed of the labeling unit 110, and causes the labeling unit 110 to coil 10. To the side.

At this time, the buffer unit 113 to mitigate the shock transmitted to the adsorption plate 115a and the coil 10 as the adsorption plate 115a is pressed on the coil.

Mitigates the shock delivered.

As the labeling unit 110 is pressed toward the coil 10 as described above, the rear surface of the label 20 is adhered to the side end surface or the outer circumferential surface of the coil 10. Thereafter, when the vacuum exhaust of the suction flow path 115a 'is released, the label 20 adhered to the coil 10 is separated from the suction plate 115a.

As described above, the coil packaging labeling device 100 can increase the utilization of the robot 130 and automate the labeling process, thereby reducing labor costs, preventing safety accidents, shortening the process time and improving productivity. have.
