03 Operation

The label roll is to be installed on the rotary drum. The label reel is routed through its track to the rotary label cutter assembly through the feed roller. The length of the label is controlled by PLC, with the help of Color photo-cell, sensing the “I” mark on the label. Then the label length is cut by the label cutter assembly. The label is then transferred to the vacuum drum by air pressure and vacuum system and the label is held firmly at vacuum drum. During the rotation the label takes the hot melt glue from the glue drum on its leading edge and trailing edge. The hot melt glue is transferred by the pump, mounted on the glue heating tank. The bottles are transferred by the feed star and positioned to the rotary vacuum drum. The bottle starts rotating, when comes in contact with the drum and the label is rolled onto the bottle against the pressure of roll-on press pad. The bottles are then transferred to the exit of the machine by the conveyor system. All the movements are controlled by P.L.C. and electro-pneumatic controls.
