Positioning Labeling Machine DTB

Keypack Intelligent Positioning Labeling Machine DTB is engineered for precise, automatic label application on round plastic bottles across high-speed inline production environments. It delivers consistent label placement at 30–80 bottles/min using photoelectric bottle detection, a pre-label feeding system, and a label tension control mechanism. Ideal for food, beverage, pharmaceutical, nutraceutical, and industrial packaging lines requiring reliable, labor-saving labeling automation.

Product Overview

The Keypack Intelligent (kunbupack) DTB Positioning Labeling Machine is a fully automatic inline labeling system designed for round plastic bottles with a body diameter of ≤100mm and a height range of 40–180mm. Bottles are conveyed through the feeding track and separated at equal intervals by an adjustable bottle-spacing mechanism. A SICK photoelectric sensor detects each passing bottle and triggers the drive system to dispense a label. The tension control system maintains consistent label strip tension throughout the process, ensuring stable label feeding and uniform label start position. After optional coding via an integrated coding machine, the label positioning sensor measures the label length and advances the strip to the correct position. The label is then automatically peeled and applied flat and accurately onto the bottle surface by the labeling and pressing components, completing the full labeling cycle without manual intervention.

The control interface supports Chinese or bilingual (Chinese/English) operation, making it straightforward to set up and adjust parameters. The machine is designed for intelligent integration with upstream and downstream production line equipment, enabling coordinated, fully automatic operation without dedicated operator attendance.

Key Features and Machine Characteristics

• High Compatibility: Accommodates a wide range of round bottle sizes (diameter ≤100mm, height 40–180mm) and supports both single and double label application, reducing the need for multiple dedicated machines.
• Label Tension Control System: The tensioning design stabilizes label strip movement, ensuring consistent coding quality, accurate label length control, and uniform label start position across production runs.
• Pre-label Feeding System: Stable label dispensing with smooth, wrinkle-free application and high positional accuracy, reducing label waste and rework.
• Adaptive Label Pressing: The rolling label-pressing mechanism adapts to different bottle profiles, maintaining labeling quality across varying bottle geometries.
• Bilingual Touch Panel Operation: Chinese or Chinese/English control interface for straightforward parameter adjustment and ease of use across different operator teams.
• Fully Automatic Inline Operation: Intelligent integration with upstream and downstream equipment enables coordinated production line control. Bottles trigger automatic label dispensing via photoelectric sensor — no dedicated operator required during normal operation, reducing labor costs.
• Optional Circumferential Positioning Detection: An optional circumferential positioning detection device enables label application at a specified angular position on the bottle surface, supporting orientation-sensitive labeling requirements.
• Industrial-Grade Components: Key electrical and pneumatic components sourced from SICK (Germany), Delta (Taiwan), Schneider (France), and Airtac (Germany) for reliable long-term industrial performance.

Application Areas

• Food & Beverage: Round plastic bottles for sauces, condiments, juices, dairy products, and drinking water — automatic inline label application at 30–80 bottles/min.
• Pharmaceutical: Round plastic medicine bottles and supplement containers requiring precise, consistent label placement with high positional accuracy.
• Nutraceutical: Protein powders, vitamins, and health supplement bottles in round plastic formats, including orientation-sensitive labeling with optional circumferential positioning.
• Cosmetics & Personal Care: Round plastic bottles for lotions, shampoos, and liquid personal care products where smooth, wrinkle-free label application is required.
• Industrial & Chemical: Round plastic containers for lubricants, cleaning agents, and industrial liquids requiring durable self-adhesive label application.
• Pet Food: Round plastic bottles and containers for liquid pet nutrition products on automated packaging lines.
