Built around a heavy-duty welded frame and powered by a Siemens PLC control system with Omron sensors, the Wanying case packer operates reliably at speeds up to 25 cases per minute while maintaining gentle product handling—critical for glass bottles containing fermented bean curd or sauce, as well as lightweight PET bottles for purified water. With over 1,300 clients served across the beverage and food processing sectors, we have refined our case packing technology to deliver measurable reductions in labor costs, material waste, and downtime, making it the preferred choice for small-to-medium enterprises seeking to automate without over-investing in overly complex systems.

Machine Overview – Beyond Traditional Case Packing

1 What Makes This Automatic Case Packer Different?

Most case packing equipment on the market today falls into one of two categories: overly simplistic semi-automatic machines that still require manual case setup, or highly complex, high-speed systems designed for multinational corporations with unlimited budgets. The Wanying Automatic Case Packing Machine occupies the sweet spot between these extremes—it delivers full automation with industrial-grade components, yet remains affordable, maintainable, and adaptable to the real-world production constraints faced by regional food and beverage manufacturers.Our machine operates on a straightforward yet highly engineered principle:

· Product infeed – Containers are conveyed from upstream filling and labeling equipment in a single file or multiple lanes

· Collation and grouping – Products are arranged into predetermined pack patterns (e.g., 3×4, 4×6) using servo-driven lane dividers and stop-gate mechanisms

· Case forming – Flat corrugated blanks are pulled from a vertical magazine, erected into open cases, and bottom-sealed using hot-melt adhesive

· Product loading – The collated product group is gently pushed into the open case using a dual-rod pusher with adjustable speed and pressure control

· Case closing and sealing – Top flaps are folded and sealed with adhesive or tape, and the finished case is discharged to the downstream palletizing or strapping station

2 Design Philosophy – Built for Food Processing Environments

Every aspect of the Wanying case packer's design reflects our deep understanding of food plant conditions:

· Stainless steel contact surfaces – All areas that may contact product or packaging materials are fabricated from food-grade 304 stainless steel or anodized aluminum

· IP55-rated electrical enclosure – Protects sensitive electronics from moisture, dust, and washdown procedures common in dairy and juice facilities

· Easy-access maintenance panels – Hinged doors with quick-release latches allow operators to access glue systems, drive chains, and sensors without tools

· Floor-level blank magazine – Operators can reload corrugated blanks safely without climbing or using ladders, reducing ergonomic strain during shift changes

3 Technical Specifications at a Glance

Why This Machine Earns Your Trust

1 Experience – Field-Proven Across Diverse Industries

Wanying's journey in case packing automation began not in a design office, but on the production floors of our earliest clients. We listened to operators frustrated with frequent jams, maintenance teams tired of hard-to-source spare parts, and plant managers exasperated by the high cost of training new staff on overly complicated European machinery. Each generation of our case packer has incorporated direct feedback from these real-world experiences.Our team has personally supervised over 200 case packer installations across China's major food-producing regions—from the soybean processing hubs of Heilongjiang to the condiment clusters of Guangdong and the dairy corridors of Inner Mongolia. This hands-on exposure has given us practical knowledge that no textbook can provide: how different corrugated board qualities affect blank feeding, how ambient humidity impacts glue curing time, and how product temperature variations influence collation accuracy.

Real-World Use Case 1 – Juice Concentrate Producer in Shaanxi

A fruit juice processor packing 1-liter aseptic cartons into 6-pack cases approached us with a specific problem: their existing case packer from a European supplier required a dedicated technician on every shift to clear jams caused by slight variations in carton dimensions. The machine was also consuming excessive glue—over 40% more than the manufacturer's claimed usage.Wanying solution implemented:

· Installed our automatic case packer with servo-controlled blank feeding and a redesigned carton infeed section

· Integrated a glue consumption monitoring system with alarm thresholds

· Provided on-site training for three shifts over five days

Results documented after 4 months:

· Jam frequency reduced from an average of 8 per shift to 1 every 3 shifts

· Glue consumption decreased by 32%, saving approximately ¥45,000 annually

· The client eliminated the dedicated technician position, reallocating that role to quality inspection

· Machine uptime improved from 82% to 96.5% , directly increasing daily output by 14%

2 Expertise – Specialized Knowledge of Container Handling

While many equipment suppliers offer generic case packers that treat all products the same, Wanying's engineering team possesses specialized expertise in handling the unique challenges posed by liquid food containers:

· Glass bottle fragility – Our pusher system features adjustable acceleration/deceleration profiles to prevent impact damage. The contact face uses polyurethane pads that cushion bottles during loading.

· PET bottle flexibility – Thin-walled PET bottles can deform under pressure. Our lane dividers are spring-loaded to accommodate slight diameter variations without squeezing containers out of alignment.

· Pouch and sachet stability – Flexible packaging tends to shift during collation. We employ magnetic hold-down plates and low-friction guide rails to maintain product positioning.

This depth of expertise extends to understanding the total system context—our case packer communicates with upstream fillers and downstream palletizers through industry-standard protocols, ensuring that speed fluctuations on one machine do not cause bottle-necking elsewhere.

3 Authoritativeness – Recognized by Industry Leaders and Component Partners

Wanying's authority in automatic case packing is validated through multiple channels:

· Technical patents – We hold three active patents related to case blank separation mechanisms and product grouping systems, developed specifically to address common failure points in conventional designs.

· Component partnerships – Our status as an approved OEM integrator for Siemens and Schneider Electric means we receive early access to new control technologies and direct technical support from their engineering teams.

· Client roster – The inclusion of major food groups such as Huiyuan Juice, Beidahuang Group, Huanlejia, and Tianwo Group on our client list serves as independent validation of our equipment's capability to meet large-scale production standards.

As a manufacturer that produces its own frames, forming plates, and mechanical sub-assemblies in-house, we maintain complete control over fit and finish—unlike assemblers who rely on third-party fabricators with variable quality.

4 Trustworthiness – Transparent Specifications and Honest Claims

Trust in industrial equipment is built through honest representation of capabilities. We deliberately rate our case packer at 25 cases per minute maximum, though our internal testing shows capability up to 28 cases per minute under ideal conditions. We prefer to under-promise and over-deliver, ensuring that clients receive a machine that comfortably meets their required throughput without being pushed to its operational limits.Our quality assurance process is rigorous:

· Raw material verification – Corrugated case blanks are tested for dimensional consistency before machine trials

· Sub-assembly testing – Each major module (blank magazine, collation section, sealing station) is tested individually before integration

· Full-system burn-in – Every completed machine runs continuously for 72 hours with production-equivalent blanks and product samples

· Performance documentation – Clients receive a comprehensive test report recording actual speed, sealing quality, and jam rates observed during factory acceptance testing

Key Benefits – Why This Machine Makes Business Sense

1 Direct Labor Cost Reduction

Manual case packing typically requires 3–4 operators per shift to handle product collation, case erecting, loading, and sealing. Our automatic case packer reduces this to one operator who monitors the machine, reloads blank magazines, and addresses occasional alarms. Over a two-shift operation with a 300-day working year, this translates to annual labor savings of approximately ¥150,000–¥250,000 depending on local wage rates.

2 Material Savings Through Precise Sealing

Inexperienced manual packing often results in case damage due to overloading, under-gluing, or improper flap folding. Our machine applies adhesive with volumetric precision (±0.5 ml per nozzle) and ensures all flaps are fully compressed for the optimal curing time. Field data from existing clients shows average case material waste reduction of 3–5% after switching to automated packing.

3 Space Efficiency

The compact footprint of the Wanying case packer—under 5 meters in length—allows it to be integrated into existing production floors without extensive facility modifications. In many cases, it replaces a longer semi-automatic line configuration, freeing up valuable floor space for additional storage or quality inspection stations.

4 Enhanced Occupational Safety

Manual case packing involves repetitive lifting, twisting, and reaching motions that contribute to workplace musculoskeletal injuries. By automating these tasks, our machine not only improves productivity but also creates a safer work environment—a factor increasingly important for compliance with modern occupational health standards.

Operational Workflow – Step-by-Step

Real-World Use Case 2 – Purified Water Plant in Guizhou

A regional bottled water company packing 550 mL PET bottles in 24-bottle cases (4×6 pattern) faced severe challenges during peak summer months. Manual packing could not keep up with their high-speed filler, forcing them to slow the entire line.Challenge specifics:

· Filler output: 18,000 bottles/hour (300 bottles/minute)

· Manual packing capacity: only 12 cases/minute (288 bottles/minute)

· Bottle-neck resulted in 20% production loss during peak demand

Wanying solution:

· Installed automatic case packer rated at 25 cases/minute (600 bottles/minute)

· Integrated with existing conveyor system via Ethernet communication

· Added a case blank magazine with 500-blank capacity for extended run time

Results after 8 weeks:

· Bottle-neck eliminated; filler now runs at full speed

· Production loss during peak months reduced from 20% to 2% (attributed to upstream material supply)

· Return on investment achieved in 9 months

· The client has since ordered a second unit for their new production hall

Customization Options

Recognizing that no two production environments are identical, Wanying offers multiple customization paths for our automatic case packing machine:

Frequently Asked Questions (FAQ)

Q1: Can the Wanying automatic case packer handle multiple case sizes on the same shift, and how long does a size change take?

 A: Yes, our machine stores up to 50 recipe profiles in the PLC memory, each containing all parameters for a specific case size and pack pattern. A standard size change (adjusting blank magazine guides, folding plates, and product lane dividers) takes approximately 10–15 minutes with manual adjustments. For clients requiring frequent changeovers—for example, a co-packer running different products for multiple brands—we offer an optional motorized quick-change system that reduces changeover time to under 5 minutes with the push of a button. This option includes servo-driven guide adjustments and automatic position verification using linear encoders.

Q2: What is the typical maintenance schedule, and how easy is it to source spare parts? 

A: We design our case packer for minimal planned maintenance. The recommended schedule is:

· Daily – Wipe down glue nozzles; visually inspect blank feeding and product infeed; check air filters

· Weekly – Lubricate chain drives and guide rails (grease points clearly marked); inspect sensor lenses for contamination

· Monthly – Check glue tank filter; inspect drive belt tension; verify all electrical connections are tight

· Quarterly – Replace glue system filters; inspect wear plates and pusher pad; calibrate sensors if needed

As a direct supplier of spare parts, we maintain inventory of all high-wear components (sensors, belts, nozzles, guide plates) in our central warehouse. Standard parts ship within 24 hours of order; custom fabrications (forming plates, special guides) ship within 5–7 business days. We also provide a recommended spare parts kit with the initial machine purchase, ensuring you have critical components on hand for immediate replacement.

Q3: How does the machine handle product jams or misfeeds without causing equipment damage? 

A: This is one of the most important safety features of our design. The Wanying case packer incorporates a three-layer protection system:

· Torque limiting clutches on all servo-driven axes – if a jam creates resistance above the set threshold, the clutch disengages before any mechanical component bends or breaks

· Photoelectric presence sensors at multiple points along the product path – if a container is missing, tilted, or out of position, the machine automatically pauses the packing cycle and alerts the operator through the HMI without attempting to push forward

· Pressure-sensitive edge detection on the blank magazine – if a blank double-feeds or misfeeds, the forming station retracts and the machine alerts the operator to clear the misfeed before resuming

When a jam does occur (which is rare—our field data shows an average of less than one jam per 10,000 packing cycles), the recovery process is straightforward: operators simply clear the obstruction using the HMI's "manual mode" controls, which allow step-by-step movement of each axis for safe obstruction removal. No specialized tools are needed for most clearing operations.
