The Automatic Sleeve Labeling Machine is designed for efficient and precise labeling of products using high-performance components and flexible configuration options. It integrates advanced PLC programmable logic control from Panasonic for precise operation and features a servo-driven traction motor system by LEADSHINE, ensuring reliable and consistent labeling speed. With label sensors from LEUZE or SICK and a user-friendly human-machine interface from SAMKOOM, this machine offers seamless control and monitoring of the labeling process. The labeling accuracy is maintained at ±1mm, allowing for high precision even with variable product dimensions.
Features and Components
- Label Dispensing Mechanism: Constructed from durable stainless steel and aluminum alloy, this unit supports consistent and efficient label release, enhancing the operational life of the machine.
- Feeding and Cutting Mechanism: Equipped with diamond and aluminum alloy components, alongside specialized rubberized parts, this mechanism ensures a smooth and accurate label feed, accommodating a wide range of label sizes (20-200mm in length) and supplies up to an external diameter of 500mm.
- Conveyor System: The stainless steel and aluminum alloy conveyor efficiently transports products through the machine, coordinating with the labeling system to achieve speeds of up to 120 pieces per minute, depending on product and label dimensions.

This machine provides a customizable setup, adaptable to specific client needs and production requirements, with adjustments made for optimal efficiency within the same class of configurations.
Knife Disc Assembly
The knife disc assembly includes a set of blades configured in a planetary arrangement with an offset crankshaft structure, designed to precisely cut the shrink film as it moves along the labeling path.
Machine Frame
The main frame of the machine is constructed from anodized aluminum and 304 stainless steel, providing stable support for the machine and securely anchoring the conveyor belt system.
Shrink Tunnel (Electric or Steam)
Utilizing either electric heating or steam, the shrink tunnel evenly applies heat to the labels on the bottles, ensuring the labels tightly adhere and conform to the contours of each bottle.
Drive Unit
Equipped with one or two servo motor systems that synchronize perfectly to ensure the shrink film is fed at a consistent, fixed length, maintaining the accuracy of each label cut.
Bottle Separation Screw
The separation screw controls the spacing of bottles on the conveyor belt, ensuring that each bottle is positioned at a precise interval to allow accurate label application.
Bottle Holding Assembly
Positioned on either side of the conveyor, this assembly stabilizes the bottles as they move, preventing wobbling during transport. It features a single handwheel for easy height and clamp positioning adjustments, facilitating precise label height alignment.
Three-Color Warning Light
A three-color indicator light system displays machine status: green for normal operation, yellow flashing when film material is low, and red flashing to signal any operational issues.
Centering Column
This component expands the label film, keeping it in position for precise transmission and cutting, allowing each label to be applied seamlessly around each bottle.
Photocell Mount Assembly
Equipped with a photocell sensor, this mount detects label position by emitting signals to the control system, allowing exact positioning adjustments to ensure labels are cut at the correct length.
Brush Assembly
With rubber bristles, the brush assembly ensures each applied label is firmly pressed into position on the bottle surface, enhancing the quality of label adherence.
Label Brush Down Assembly
Using a synchronized adjustment mechanism, this assembly aligns two brushing wheels beneath the centering column to lightly contact the rollers, smoothly pushing each label onto the bottle.
Material Rack Assembly
The material rack holds the label film roll with adjustable paper rings from 5” to 10”, feeding the film through a set of roller conveyors driven by a reduction motor for controlled film output.
Conveyor Belt
Driven by a variable frequency drive, the conveyor belt’s speed can be adjusted to match production capacity, ensuring synchronized movement with the rest of the labeling process.
Bottle Detection Sensor
Positioned to monitor bottle location on the conveyor, this sensor triggers the label application when a bottle reaches the correct labeling point.
Label Feed Assembly
Consisting of a feed box to control label tension and a top-mounted feed frame for label direction positioning, this assembly maintains smooth, controlled film transport to the cutting station.
Human-Machine Interface (HMI)
Serving as the control center of the machine, the HMI organizes operational functions into manual, automatic, setup, and error display modes, with additional control buttons and knobs for label application adjustments.
