The Quantitative Impact of Four-Station Automated Feeding on Labor Costs
Revolutionizing Efficiency in Large-Scale Laundry Lines
In the transition from manual to automated flatwork processing, the feeder machine serves as the critical entry point that dictates the speed of the entire ironing and folding line. For large-scale operations, the four station automatic laundry feeder machine acts as a massive labor multiplier. Jiangsu Sea-lion Machinery Co., Ltd., established in 1969 as China’s oldest industrial laundry manufacturer, has leveraged 55 years of R&D to develop the four station feeder, a system designed to replace high-intensity manual labor with high-precision automation.
I. Quantitative Labor Cost Reduction
- Manpower Compression: In a traditional manual feeding setup for a high-speed ironer, 6 to 8 operators are often required to shake, spread, and feed sheets to keep up with the ironer's speed. A Jiangsu Sea-lion Machinery Co., Ltd. four-station feeder allows just 2 to 4 operators to achieve the same or higher throughput, effectively cutting direct labor costs by 50-60%.
- Increased Pieces Per Hour (PPH): Manual feeding typically caps at 400-500 sheets per hour due to human fatigue. Our automated four-station system utilizes PLC-driven synchronous feeding, pushing the output to 800-1,200 pieces per hour. This doubling of productivity per worker significantly lowers the "cost per piece."
- Reduction in Secondary Sorting: The automatic centering and edge-alignment sensors reduce "re-wash" or "re-iron" rates caused by human error (such as skewed feeding or folded edges), saving additional labor hours in the quality control department.

Coordinating Buffer Storage and Feeding Cycles in High-Speed Ironing Lines
Maximizing Line Efficiency through Synchronized Automation
In high-volume flatwork processing, the ironer is the most expensive asset; any second it spends "empty" due to slow manual feeding is lost revenue. A multi station feeder solves this by decoupling the operator's speed from the ironer's speed. Jiangsu Sea-lion Machinery Co., Ltd., established in 1969 as China’s oldest industrial laundry manufacturer, has utilized 55 years of R&D to perfect the synchronization between buffer storage and feeding discharge. Our multi station feeder ensures that a linen item is always "in the queue," ready to be injected the microsecond the previous one clears.
I. How Buffer Storage Eliminates Idle Time
- Asynchronous Input vs. Synchronous Output: While operators load linens at varying speeds across different stations, the PLC (Programmable Logic Controller) manages a "holding zone" or buffer. This allows the system to store up to 4-6 ready-to-spread items, ensuring the discharge conveyor never waits for a human operator.
- Smart Discharge Sequencing: Jiangsu Sea-lion Machinery Co., Ltd. systems use infrared sensors to detect the trailing edge of the current linen. The buffer system then pre-accelerates the next item from the station that finished its preparation first, maintaining a gap of only a few centimeters between pieces.
- Servo-Driven Spreading: To prevent bottlenecks, the spreading clamps utilize high-speed servo motors. This allows the machine to spread a king-sized sheet in a fraction of the time it takes a manual worker, feeding the ironer at speeds up to 50 meters per minute.
