Stick Pack Cartoning Machine For Coffee Sticks Explained

Automating Stick Pack Cartoning for Coffee and Sachet Products

Coffee stick packs, along with other single-serve sachet formats, present a specific packaging challenge: they must be counted, folded (when a leaflet is included), inserted, and sealed into cartons at high volume without errors, while keeping labor costs and quality risks under control. Manual cartoning of these formats commonly drives up labor costs and introduces the risk of missed or misplaced products and leaflets, particularly when upstream and downstream packaging steps are not properly coordinated. Guangdong Rich Packing Machinery Co., Ltd., operating under the brand name Rich Packing, has built its automatic cartoning equipment specifically to address these pain points across pharmaceutical, chemical, electronics, and food production environments—including sachet-type products such as coffee sticks.

Understanding the Pain Points Behind Stick Pack Cartoning

Packaging operations handling sachets and stick-format products face three recurring difficulties. First, manual cartoning labor costs remain a persistent operating expense. Second, quality risks emerge from missed or misplaced products and leaflets during the insertion process. Third, continuous production requires tight coordination between upstream and downstream packaging equipment—if a cartoning step cannot keep pace or integrate smoothly, the entire line loses efficiency. Rich Packing’s positioning as a manufacturer of automatic cartoning machinery directly responds to these three concerns by combining optical, electronic, pneumatic, and mechanical technologies into a single automated system.

The RQ-ZH-120L Automatic Cartoning Machine

The RQ-ZH-120L Automatic Cartoning Machine is Rich Packing’s automatic vertical cartoning equipment, positioned for small and medium production volumes and for GMP-compliant environments. It is designed to handle diverse product formats and to complete the full cartoning process—from feeding through carton forming, conveying, leaflet folding, inspection, product insertion, batch printing, tongue closing, carton sealing, and missing-product rejection—within one machine.

One Machine, Multiple Product Formats

A key differentiated advantage of the RQ-ZH-120L is that one machine handles multiple product formats and specifications. This flexibility is directly relevant to sachet-based products, including coffee sticks, since it means production lines do not need separate machinery for every packaging variation. The machine’s industry adaptation covers pharmaceutical products (blister packs, bottles, and tubes under GMP compliance), chemical products (tubes, ointments, and sachets), electronics (electronic cigarettes and related items), and food (sachets and comparable packaged products).

Speed Through Dual Servo Feeding

The RQ-ZH-120L is built around a feeding system with dual servo motors, which achieves 125 cartons per minute and performs faster and more stable feeding than a one-servo-motor configuration. The machine’s speed range spans 35 to 125 cartons per minute, giving operators flexibility to match line speed with product requirements while maintaining stability across the full range.

Dual Inspection for Quality Assurance

To address the quality risks associated with missed or misplaced products and leaflets, the RQ-ZH-120L applies a dual inspection methodology: products and leaflets are verified before insertion, and verified again once inside the carton. This two-stage check is designed to detect incorrect quantities and improper carton placement, covering the full detection cycle rather than relying on a single inspection point.

Supporting this inspection approach is a high level of intelligence built into the machine, with dense inspection points positioned at leaflet feeding, leaflet counting, product loading, product counting, and carton positioning. This density of monitoring supports accurate quantity tracking across the entire process, not just at the final result.

Visualized Monitoring and Maintenance

Faults and counting data are fully visualized and viewable on the touch screen at any time, which is intended to make maintenance easier for operators. In addition, all components are clearly numbered, supporting convenient routine maintenance. Together, these features are meant to reduce downtime and simplify troubleshooting during continuous operation.

Built for Durability and Continuous Operation

The RQ-ZH-120L is constructed from stainless steel or nickel chrome plating, materials chosen for stable chemical properties that provide corrosion resistance, non-toxicity, and safety. Welded areas receive tempering treatment to extend service life. A dual clutch design activates bidirectional protection when the main motor is overloaded or the leaflet folder faults, protecting both the equipment and the operator. The machine is described as delivering stable operation suitable for continuous 24-hour production.

Compact Footprint for Easier Transport

Despite its capabilities, the RQ-ZH-120L occupies approximately 3㎡, a compact footprint that eases transport and installation within existing facility layouts—an important consideration for manufacturers integrating the machine into established coffee stick or sachet production lines.

Component Quality and Integration

The RQ-ZH-120L uses electrical and mechanical components sourced from established international brands, including Panasonic servo motors and drivers, an SEW main motor, a Danfoss frequency converter, Omron sensors and switches, a Siemens PLC, SMC solenoid valves and pneumatic components, and a Schneider emergency stop button, among others. This component selection is intended to help ensure reliable quality across the machine’s electronic, pneumatic, and mechanical systems.

Beyond standalone operation, the RQ-ZH-120L is built for integration. It connects with end sealers, blister packaging machines, counting and bottling lines, cellophane overwrapping machines, strapping machines, and other cartoning machines according to production requirements. This platform compatibility allows the machine to be deployed either as a standalone unit or as part of a coordinated production line that spans upstream feeding and downstream packaging stages.

Serving Multiple Industries with One Platform

Rich Packing’s business scope covers pharmaceutical, chemical, electronics, and food industries, with the RQ-ZH-120L positioned toward small and medium production operations. For food-sector applications such as coffee sticks and other sachet formats, the machine’s combination of format flexibility, dual servo feeding speed, and dual inspection accuracy addresses the core operational concerns of labor cost reduction, error prevention, and line coordination.

Conclusion

For manufacturers packaging coffee sticks or similar sachet-based products, cartoning automation needs to solve three interconnected problems: reducing manual labor costs, preventing quality issues from missed or misplaced items, and integrating smoothly with the rest of the production line. Rich Packing’s RQ-ZH-120L Automatic Cartoning Machine, built by Guangdong Rich Packing Machinery Co., Ltd., addresses these needs through its integration of optical, electronic, pneumatic, and mechanical technologies, its dual servo feeding system, its dual inspection process, and its compatibility with a range of upstream and downstream packaging equipment. Manufacturers can review the technical parameters and configuration details directly against their own product and leaflet specifications to assess fit for their specific coffee stick or sachet packaging line.
