The Continuous Label Roll-Feed Labeling Machine is a fully automatic unit with electro-pneumatic controls for precise labeling. It features a base, label cutter, and glue assembly constructed from durable mild and alloy steels with a painted or hard chrome finish. The conveyor is made of S.S.304, while the chain is thermoplastic for reliable operation. Stainless steel shafts, column assemblies, and star housings ensure durability. Guides and stars are crafted from S.S.304, UHMWPE, and nylon. Enclosed in an S.S.304 frame with acrylic panels, the machine is operated via a Siemens PLC with a touch screen, and speed is managed by a Siemens Variable Frequency Drive for optimal performance and control.

Operation

The label roll is mounted on a rotary drum and guided through a track to the rotary label cutter assembly via a feed roller. The PLC system, using a color photocell to detect the “I” mark, precisely controls and cuts the label length. The label is then transferred to the vacuum drum using air pressure and vacuum systems, where it is securely held. As the drum rotates, the label’s edges are coated with hot melt glue from the glue drum, with glue pumped from the heating tank. Bottles are fed by a star wheel, rotated against the drum, and labeled using a roll-on press pad. The finished, labeled bottles are conveyed out of the machine. All functions are controlled by a PLC and electro-pneumatic systems for optimal performance.
