On fresh-food e-commerce and supermarket packaging lines, weighing, label printing and labeling are often done at separate stations or by hand. This fragmented workflow delays data flow and easily produces mismatches between weight and barcode information. In their research, the Wanzhi Automation technical team found that breaking down data silos for efficient packaging is a common industry problem. This article explains how integrated packaging equipment performs in practice.
Pain points on conventional packaging lines and the integrated solution
Conventional fresh-food packaging lines face many pain points. After manual weighing, the operator keys the weight into the system, prints a label and applies it by hand, which is laborious and limits capacity. During promotional peaks, manual steps easily become a bottleneck, and missed or wrong labels are hard to avoid. Wanzhi Automation developed the WZ-600 print-and-apply labeling machine to solve this. It tightly integrates inline weighing, industrial on-demand printing and automatic labeling: material passing over the weighing platform has its data collected automatically, the system matches product information and generates a label in real time, and the labeling head applies it automatically. Intermediate manual steps are eliminated entirely, achieving truly unmanned flow.
Data linkage and mechanical structure
The WZ-600’s core is real-time data linkage and stable mechanical coordination. On the data side, after automatic weighing, data is synced with the back-end product database to match product name, unit price and specification precisely. Weighing accuracy reaches ±2g, ensuring weight and price information is error-free and fully meeting fresh-food supermarket traceability standards. On the printing side, an industrial high-speed on-demand printer receives commands and dispenses labels as needed, removing the need to stock large numbers of pre-printed labels and reducing consumable inventory costs and management complexity. On the labeling side, photoelectric sensors detect the workpiece precisely, and the pneumatic labeling structure provides stable, even labeling pressure. With a standard air supply of 0.6~0.8Mpa, the machine supports long continuous packaging runs. Its stable high-speed capacity reaches 30-50PCS/min, easily matching the high-speed portioning pace of upstream fresh-food sorting lines. An industrial PC terminal lets product records and print templates be edited and stored visually, so changeover is convenient.
Practical advice and applications
When deploying and selecting equipment, configure it to your packaging process. The WZ-600 switches freely between top-surface and bottom labeling and handles bags, boxes, blister packs and other formats, so one machine serves many fresh-food categories. For fresh-food supermarket packaging, prepared meal processing, agricultural produce sorting and e-commerce express logistics, this automatic labeling machine noticeably raises line automation and return on investment. In practice, clean the photoelectric sensors regularly to maintain detection accuracy, and fine-tune the pneumatic labeling pressure to suit each packaging material’s surface, so labels stay flat with no bubbles.
FAQ
What should we do if labels print unclearly during print-and-apply labeling?
First check the print head for dust and make sure the ribbon and label paper are installed flat. Clean the print head regularly with a cotton swab dipped in anhydrous alcohol, and make sure consumables meet industrial standards.
How should label position drift be adjusted?
Check that material conveying is stable, and adjust the sensing position and sensitivity of the photoelectric sensor. Also confirm that the peel plate angle and pneumatic pressure of the labeling head are within a reasonable range.
How does the machine switch between top-surface and bottom labeling modes?
The WZ-600 uses a modular design: select the corresponding mode on the industrial PC terminal and physically move the labeling head above or below the material to label the top or the bottom.
