In an exemplary implementation of the present invention, the
The sensor 910, sends a signal to camera unit 920 informing a new label in the label path (shown as arrow). The camera unit 920 captures image of the new label in the label path (shown as arrow) and compares with a predetermined configurations so as to identify a good label or a defective label. In a preferred embodiment, defective labels are those labels those do not match a predetermined parameters of good label, for a non-limiting example, a label with different color or missing a part or whole of a text, or a logo, or a vision, or a coding by various coding techniques or a barcode information is the defective label.
The camera unit 920 sends a defective label signal to an activator unit 930. The activator unit 930 activates a push mechanism 940, wherein, the push mechanism 940 pushes a movable plate 950 out of the static guide roller 960 so as to create an angular motion to the label path (shown as arrow) at point of contact of the label path (shown as arrow) and the static guide roller 960. The activator unit 930 also sends a unique id for which the push mechanism 940 has to react. At the time when the defective label with the unique id comes to contact 970 with the static guide roller 960, the push mechanism 940 pushes the movable plate 950 out of the static guide roller 960.
Once the movable plate 950 comes out of the static guide roller 960, it creates an angular motion to the label path (shown as arrow) at 970 and hence creates a mechanical pressure to the defective label at 970 so as initial of the defective label comes out due to said mechanical pressure. The defective label then sticks to a roll 980 of a motorized roll winder 990 of a collector unit which is controlled by a driver pulley. The present figure
The label path (shown as arrow) then has a vacant space wherein at a destination station a required product is not labeled due to lack of label.
In yet another embodiment, the signal can be generated either for each label of the plurality of label in the label path (shown as arrow) or only for the defective label in the plurality of labels in the label path (shown as arrow), further wherein, the signal is generated with a unique identity of label.
In a preferred embodiment, the activator unit 930, activates rotation of the motorized roll winder 990. Hence once initial of the defective label at 970 sticks to the roll 980, due to a force created by rotation of the motorized roll winder 990, whole defective label is plucked out of the label path (shown as arrow) leaving the space blank.

In an exemplary implementation of the present invention, the
The sensor 1010, sends a signal to camera unit 1020 informing a new label in the label path (shown as arrow). The camera unit 1020 captures image of the new label in the label path (shown as arrow) and compares with a predetermined configurations so as to identify a good label or a defective label. In a preferred embodiment, defective labels are those labels those do not match a predetermined parameters of good label, for a non-limiting example, a label with different color or missing a part or whole of a text, or a logo, or a vision, or a coding by various coding techniques or a barcode information is the defective label.
The camera unit 1020 sends a good label signal to an activator unit 1030. The activator unit 1030 sends a good label signal to a push mechanism 1040, wherein, the push mechanism 1040 informs a movable plate 1050 to stay in the static guide roller 1060 so as to create a smooth movement of the label path (shown as arrow).
