Automatic Case Erector Case Packing and Carton Sealing Line

The automated carton opening, filling and sealing production line is a set of automated packaging equipment that integrates carton opening, product filling, carton sealing and subsequent palletising. It enables continuous operation from cardboard forming to the output of finished cartons, effectively reducing manual intervention whilst enhancing packaging efficiency, consistency and the overall operational stability of the production line. It is suitable for continuous production in modern factories.

Composition and Workflow

The carton forming, filling and sealing production line is an end-of-line (EOL) automated packaging system, typically comprising an automatic carton opener, a robotic filling system, an automatic carton sealer and palletising equipment. Each piece of equipment is connected via a conveyor system to enable fully automated operation throughout the entire process.

During production, flat cardboard sheets first enter the automatic carton opener, where the equipment uses mechanical mechanisms to fold, form and seal the bottom of the cartons. Subsequently, the products are conveyed and positioned, after which a robot or automatic gripping mechanism fills the cartons according to preset quantities and arrangements. Once filled, the cartons automatically proceed to the sealing station, where the top is sealed using either tape or hot-melt adhesive. Finally, they are conveyed to the automatic palletising area, ready for warehousing and logistics transport.

The entire system can be custom-designed according to product dimensions, packaging specifications and factory layout, enabling rapid changeovers between different product specifications to meet the demands of multi-variety, small-batch and continuous production.

Advantages and Application Value

Compared with traditional manual packaging, the automated case-packing and sealing production line operates continuously and reliably, significantly reducing the physical strain on workers whilst minimising issues such as missed items, incorrect packing and inconsistent packaging quality caused by human error.

The equipment utilises a PLC control system combined with servo drive technology to enable automatic detection, positioning, fault alarms and parameter adjustment, thereby enhancing the operational stability of the entire production line. The robotic case-packing system can automatically adjust its gripping method according to different products, making it suitable for both regular-shaped packaging and certain irregularly shaped products.

In terms of production efficiency, an automated packaging system typically operates continuously and can be synchronised with high-speed production equipment, preventing downstream packaging from becoming a bottleneck in the production line. Furthermore, as the formed cartons are of consistent dimensions and the sealing quality is stable, this helps to reduce the breakage rate during transport and improve the standardisation of product packaging.

Scope of Application

Automated carton opening, filling and sealing production lines are not only suitable for the end-of-line packaging of wet wipe production lines, but are also widely used in industries such as household paper, food and beverages, personal care products and pharmaceuticals. In particular, for enterprises requiring continuous production, frequent specification changes and improved packaging consistency, customised carton forming, filling and sealing production lines can be configured with different filling methods, sealing processes and palletising solutions according to product characteristics, thereby enhancing production efficiency whilst reducing long-term operating costs.
