Blister Cartoning Machine With Dual Servo Feeding Explained

 Why Manufacturers Are Rethinking Cartoning Workflows

Packaging operations across the pharmaceutical, chemical, electronics, and food industries continue to face a familiar set of pressures: the labor cost associated with manual cartoning, quality risks arising from missed or misplaced products and leaflets, and the operational friction of coordinating cartoning steps with upstream and downstream packaging equipment. These pain points have pushed manufacturers to look closely at automated solutions that can handle diverse product formats while maintaining consistent quality control. A blister cartoning machine with dual servo feeding addresses each of these concerns directly, and Guangdong Rich Packing Machinery Co., Ltd., operating under the brand Rich Packing, has built its RQ-ZH-120L Automatic Cartoning Machine specifically around this need.

Guangdong Rich Packing Machinery Co., Ltd. and Its Market Position

Headquartered in Building D, NO.226, Qiaotou Street, Haizhu District, Guangzhou City, Guangdong Rich Packing Machinery Co., Ltd. manufactures automatic cartoning machinery that combines optical, electronic, pneumatic, and mechanical technologies. The company's stated strategic positioning centers on raising automation levels and reducing labor costs for packaging lines. Its RQ-ZH-120L model is positioned specifically for small and medium production volumes and for GMP-compliant environments, which makes it relevant to pharmaceutical operations that must meet regulatory expectations while also serving chemical, electronics, and food producers with comparable cartoning needs.

What Defines a Dual Servo Feeding Cartoning System

Dual servo feeding refers to a feeding system built around two servo motors rather than a single unit. In the RQ-ZH-120L, this configuration reaches a cartoning speed of up to 125 cartons per minute, with feeding performance described as faster and more stable compared with a one-servo-motor setup. The machine's overall speed range spans 35 to 125 cartons per minute, giving operators flexibility depending on production requirements. This feeding architecture is paired with a main motor rated at 0.75KW (220V/380V) supplied by SEW of Germany, and two 400W Panasonic servo motors (model MHMD042G1U) with matching Panasonic servo drivers (model MBDHT2510E), reflecting the mechanical basis for the machine's throughput.

Dual Inspection for Blister and Leaflet Accuracy

A recurring quality concern in cartoning is the risk of incorrect quantities or improper placement of products and leaflets inside the carton. The RQ-ZH-120L addresses this through a dual inspection methodology: products and leaflets are verified before insertion, and then verified again once inside the carton. This two-stage check is designed to detect incorrect quantities and improper carton placement at both points in the process, rather than relying on a single inspection step. Supporting this inspection function are components such as Omron fiber amplifiers (E3X-NA11), Omron optical fiber sensors (E32-ZD200), and Omron encoders (E6B2-CWZ6C), among other sensing elements listed in the machine's configuration.

High-Density Monitoring and Visualized Fault Review

Beyond the dual inspection stages, the machine incorporates what the manufacturer describes as a high level of intelligence, achieved through dense inspection points positioned at leaflet feeding, leaflet counting, product loading, product counting, and carton positioning. This arrangement is intended to provide monitoring across the full process and at the final result stage. Fault data and counting information are visualized on a touch screen, specifically a Proface GC—4408W unit, allowing operators to review equipment status and production counts at any time. This visualized monitoring approach is paired with clear numbering of all components, which is intended to simplify routine maintenance work.

 

 

Built for Durability and Operator Protection

The machine's construction uses stainless steel or nickel chrome plating, materials chosen for their stable chemical properties, corrosion resistance, non-toxicity, and safety characteristics. Welded areas receive tempering treatment aimed at extending service life. On the protection side, a dual clutch design activates bidirectional protection in the event the main motor becomes overloaded or the leaflet folder encounters a fault, which is intended to protect both the equipment and the operator. The manufacturer also notes that the machine is built for stable performance suitable for continuous 24-hour production, an important consideration for facilities running extended shifts.

Electrical Components and Technical Specifications

The RQ-ZH-120L is built using electrical components from established international brands, including Baker and Siemens, which the manufacturer states helps support reliable quality. The configuration list also includes a Siemens Smart ST40 PLC, a Danfoss FC-051P1K5S2E20H frequency converter, SMC pneumatic solenoid valves and cylinders, SICK and LEUZE photoelectric and proximity switches, and a Schneider emergency stop button, among other listed parts.

On the specification side, the machine operates on a 220V/380V 50Hz power supply with total power of 1.10 kW, and requires air pressure of at least 0.6 MPa with air consumption between 120 and 160 L/min. Carton size requirements range from 65-150mm in length, 35-85mm in width, and 12-45mm in height, with carton weight between 240-360g/㎡. Leaflet requirements cover open sizes from 78mm to 250mm in length and 85mm to 170mm in width, accommodating 1 to 4 folds, with leaflet weight between 60 g/m² and 70 g/m². The machine itself measures 2,150mm × 1,140mm × 1,800mm and weighs approximately 1,500 kg, while occupying an approximate footprint of 3㎡, which the manufacturer notes eases transport.

Integration Across the Production Line

Rather than functioning only as a standalone unit, the RQ-ZH-120L is designed to connect 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 is directly relevant to the continuous-line coordination challenge that many packaging operations face, since it allows the cartoning step to be integrated into a broader automated workflow rather than operating in isolation.

Where This Fits Across Industries

The RQ-ZH-120L's industry adaptation covers pharmaceutical cartoning for blister packs, bottles, and tubes under GMP compliance; chemical cartoning for tubes, ointments, and sachets; electronics cartoning for items such as electronic cigarettes; and food cartoning for sachets and comparable packaged products. Its positioning for small and medium production volumes suggests it is intended for operations that need automation without the scale requirements of very high-volume lines.

For manufacturers evaluating a blister cartoning machine with dual servo feeding, the combination of speed, dual-stage inspection, protective design, and line-level integration presented by Guangdong Rich Packing Machinery Co., Ltd.'s RQ-ZH-120L addresses the core pain points of labor cost, quality risk, and production coordination that originally drive interest in automated cartoning equipment.
