- Product Features: Strong bearing capacity and high rigidity; excellent positioning accuracy, suitable for back-end automatic case packing of various primary packaging forms such as bags, cans, tins and boxes; repeat positioning accuracy below 0.2mm ensures neat stacking shape.
III. Packaging Process: From Automatic Case Packing to Final Palletizing
- Automatic Sorting and Conveying: Small bags are arranged in order by the material arranging machine and enter the lane dividing conveyor.
- Weight Detection: Pass through the dynamic checkweigher, and unqualified products are automatically rejected.
- Parallel Robot Case Packing: The parallel robot case packer picks and places at a speed of 3-4 times per second, placing small bags layer by layer into cartons in a 5×4 arrangement, and automatically adjusting the suction cup angle according to material thickness during the process.
- Carton Sealing and Labeling: After the carton is full, automatically fold the cover, seal with adhesive tape, and attach traceability codes.
- Robot Palletizing: Marchi palletizing robot receives signals, grabs and stacks cartons layer by layer on pallets according to the five-flower stacking type, with a palletizing speed of 6-8 bags per minute, realizing automatic pallet output.
Customer Pain Points and Solutions
In actual production scenarios, enterprises often face three major challenges:
Pain Point 1: Low manual case packing efficiency and unstable quality.
Manual long-term operation is prone to missing packing, misalignment and irregular arrangement in cartons due to fatigue.
Solution: Marchi parallel robot case packer features high repeat positioning accuracy, stable grabbing even at high-speed movement, and can realize accurate identification and positioning of products of different sizes with the vision system, greatly reducing manual errors.
Pain Point 2: High production line labor cost and labor recruitment difficulty.
Especially in peak seasons of food and feed industries, there is an obvious labor gap in manual case packing, and the proportion of elderly workers is relatively high.
Solution: The introduction of automatic case packers can save 3 to 5 case packing workers per single line. Marchi's whole line modular design can also be upgraded in stages according to budget and capacity expansion needs, lowering the threshold of one-time investment.
Pain Point 3: Long downtime caused by multi-category switching.
Enterprises have rich product lines, and equipment debugging is time-consuming when frequently replacing packaging specifications, affecting overall output.
Solution: Marchi case packing equipment supports fast formula switching. The fixture of parallel robot can adapt to different packaging sizes, and the cross coordinate case packer can adapt to different case packing arrangement schemes by adjusting servo parameters. The Marchi team provides pre-sales scheme design, nationwide installation and commissioning and lifelong maintenance services. Starting from two major factories in Guangdong and Anhui, it quickly responds to after-sales demands of customers across the country.
IV. User Evaluation: Real Feedback from Production Lines
- Qingdao, Shandong · A Casual Food Manufacturer, Production Manager Wang Zhenguo
"We originally relied on manual case packing with 6 workers per line, and it was impossible to recruit enough workers in peak seasons. After adopting Marchi's parallel robot case packer, only 1 inspector is needed now. The speed is stable at about 350 times per minute, and small bag potato chips are packed neatly without missing packing. The most satisfying point is product switching. In the past, it needed to shut down for half an hour to adjust fixtures when changing different flavors with slightly adjusted bag sizes; now it can be switched in 2 minutes with the formula function. Marchi's after-sales response is also fast, and technicians can arrive at the site the same night from Guangzhou to Qingdao."
- Chengdu, Sichuan · A Rice Processing Enterprise, Factory Director Li Yongqiang
"We adopt Marchi cross coordinate case packer, with 4 bags of 10kg rice per carton and a total weight of 40kg. The previous Cartesian coordinate machine often grabbed deviation with a high carton corner damage rate. Marchi's equipment has a repeat positioning accuracy of ±0.2mm. After running for more than one year, there is almost no carton damage caused by inaccurate positioning. In addition, the machine has really low noise, no more than 70 decibels measured on site, and workers feedback much more comfortable than before. Marchi also helped us complete the whole line joint debugging with smooth coordination from case packing to palletizing."
- Luohe, Henan · A Condiment Manufacturer, Equipment Supervisor Liu Hui
"We use both parallel robot case packer and palletizer for packaging small bag compound seasonings. In the design scheme provided by Marchi, the checkweigher is linked with the case packer to automatically reject unqualified products and make up placement. This detail is very practical. In terms of service, it only took 25 days from contract signing to installation and commissioning with high efficiency. Now we have the highest back-end automation rate among the local peers."
