Key Features
1. Automatic Plate Feeding System with Chain Transmission
The JY-L600 features a purpose-built automatic plate feeding system that serves as the critical interface between upstream production equipment and the packaging module. Products arriving from cooling tunnels, coating drums, or forming lines are received onto precision-machined feeding plates that index in synchronization with the packaging cycle. This synchronization is achieved through a chain transmission mechanism driven by one of the machine's nine servo motors, ensuring that product spacing and orientation remain consistent throughout the transfer process.
The feeding plates are manufactured from food-grade stainless steel with polished surfaces to minimize product adhesion and facilitate cleaning during product changeovers. Plate dimensions and spacing can be customized to match specific product geometries, and the system accepts direct bolt-on integration with common confectionery production equipment through standardized mounting interfaces. This eliminates the need for intermediate conveyors or manual transfer stations, reducing both labor costs and the risk of product contamination during handling.
The chain transmission system employs hardened steel sprockets and precision roller chain running in enclosed oil-bath lubrication housings, delivering reliable operation across continuous multi-shift production schedules. Servo control of the feeding axis allows the operator to fine-tune feed timing and product pitch directly from the HMI touch screen, accommodating different product sizes without mechanical adjustments.
2. Nine Servo Motor Control Architecture
At the core of the JY-L600 is a distributed nine-servo control system that independently governs each critical motion axis of the packaging process. This architecture replaces traditional mechanical cam-and-linkage systems with fully programmable electronic motion profiles, delivering superior flexibility, repeatability, and diagnostic capability. Each servo axis -- covering film feeding, longitudinal sealing, horizontal sealing, cutting, product feeding, and auxiliary functions -- operates under closed-loop position and velocity control with encoder feedback resolution measured in microns.
The servo drives communicate over a high-speed industrial fieldbus, enabling coordinated multi-axis interpolation that maintains precise phase relationships between feeding, sealing, and cutting operations even during acceleration and deceleration ramps. This eliminates the bag-length errors and seal misalignment common in mechanically linked machines when running at variable speeds. Operators interact with the entire system through a single color touch screen HMI that displays real-time production data, servo status, alarm history, and maintenance reminders in multiple languages including English, Chinese, Spanish, and Arabic.
Recipe management is a key advantage of the servo-driven architecture. Up to 100 product recipes can be stored in the controller memory, each containing complete parameter sets for bag dimensions, sealing temperatures, film tension, feeding pitch, and speed profiles. Changing between products requires only selecting the appropriate recipe from the HMI, after which the machine automatically reconfigures all servo axes to the saved positions and motion parameters. This reduces changeover time from the 30-60 minutes typical of mechanical-adjustment machines to under 5 minutes.
3. Precision Longitudinal and Horizontal Sealing System
The sealing system of the JY-L600 employs a dual-station design with independent longitudinal and horizontal sealing modules, each optimized for its specific function within the pillow-pack forming process. The longitudinal sealing station operates on the tension principle, applying controlled pressure through high-precision gear transmission to form the back-fin seal while the packaging film is drawn through the forming collar. Heating is provided by embedded electric heating coils with multi-zone PID temperature control that maintains setpoint accuracy within +/-1 degree Celsius across the full operating range.
The horizontal sealing station features upper and lower sealing jaws driven by dedicated servo motors through precision transmission. This servo-driven approach allows the sealing dwell time to be programmed independently of machine speed, ensuring consistent seal integrity across the entire speed range from 50 to 500 bags per minute. The sealing jaws are heated by high-density cartridge heating tubes with individual temperature sensors, providing rapid heat-up from cold start and maintaining thermal stability during continuous operation. Jaw temperature, contact pressure, and dwell duration are all adjustable parameters accessible through the HMI, enabling optimization for different film materials including BOPP, CPP, PE, laminated structures, and metallized films.
A critical design feature of the horizontal sealing mechanism is the automatic jaw alignment system that compensates for thermal expansion during warm-up and sustained operation. The control system monitors jaw position through the servo encoder feedback loop and makes micro-adjustments to maintain the correct sealing gap, preventing both under-sealing that leads to package leaks and over-sealing that damages the film or causes excessive jaw wear.
4. Intelligent Film Handling with Automatic Splicing
The film handling subsystem of the JY-L600 is engineered for maximum productivity with a dual paper feed roller configuration supporting both A and B film rolls simultaneously. When the active roll approaches depletion, the automatic film splicing mechanism transfers the film path to the standby roll without stopping the machine, eliminating the downtime traditionally associated with roll changes. This feature is particularly valuable in high-volume production environments where every minute of stoppage translates directly to lost output.
Film tension is actively controlled through a dancer-arm feedback system with servo-driven unwind axes. The dancer arm measures real-time film tension and sends correction signals to the unwind servo, maintaining constant tension regardless of roll diameter or machine speed. This active tension control prevents the film stretching, wrinkling, and tracking errors that degrade print registration and seal quality in passive tension systems. The film path is designed with minimal directional changes and large-radius guide rollers to accommodate a wide range of film materials without creasing or scuffing printed surfaces.
The JY-L600 supports multiple film width and knife count configurations to optimize throughput for different product sizes. The standard configuration matrix includes five operating modes: 90-180mm film width with 2 knives delivering 200 bags per minute, 65-120mm with 3 knives at 400 bpm, 55-80mm with 4 knives at 600 bpm, 48-60mm with 5 knives at 800 bpm, and 45-55mm with 6 knives at 1000 bpm. This modular knife arrangement allows production managers to select the optimal balance between film utilization and throughput for each product SKU.
5. Photoelectric Sensor Tracking and Quality Control
The JY-L600 incorporates an advanced photoelectric sensor tracking system that ensures precise film registration and eliminates empty package production. High-speed optical sensors continuously monitor printed registration marks on the packaging film, sending position data to the servo control system that corrects film feed position in real time. This closed-loop registration control maintains cut-position accuracy within +/-0.5mm even at maximum operating speed, ensuring that printed graphics, date codes, and branding elements appear consistently positioned on every package.
The no-empty-package detection feature uses product-presence sensors positioned at the infeed to verify that each packaging cycle contains a product. When a gap in the product stream is detected -- such as during production line interruptions or feeder misfeeds -- the control system suppresses the corresponding sealing and cutting cycle, preventing the formation of empty packages that waste film material and create downstream sorting requirements. This intelligent skip function recovers automatically when product flow resumes, maintaining continuous operation without operator intervention.
Additional quality monitoring features include seal-integrity verification through temperature trend analysis, film-break detection with automatic emergency stop, and production counting with batch management. All quality events are time-stamped and logged to the controller memory for traceability and continuous improvement analysis.
6. Food-Grade Construction and Hygienic Design
Every product-contact surface on the JY-L600 is manufactured from food-grade materials selected for compliance with international food safety standards. The machine frame is constructed from stainless steel 201 with a brushed finish that resists corrosion and facilitates cleaning. All conveyor belts in the feeding and discharge sections are food-grade PU (polyurethane) that meets FDA and EU food contact material regulations. These belts are designed with quick-release tensioners that allow them to be removed for thorough cleaning or replacement without specialized tools.
The machine enclosure features sloped surfaces that prevent liquid pooling, continuous welded seams with ground-and-polished finishes that eliminate crevices where food particles could accumulate, and tool-less removable panels that provide full access to internal components for sanitation procedures. Electrical enclosures are sealed to IP54 standards, protecting control electronics from washdown moisture while maintaining accessibility for maintenance. The frame is mounted on adjustable stainless steel feet with vibration-damping pads that isolate the machine from floor-borne vibrations while allowing height adjustment for conveyor line matching.
The forming collar, sealing jaws, and cutting knives are fabricated from hardened stainless steel alloys chosen for their combination of wear resistance, thermal conductivity, and corrosion resistance. These critical tooling components are designed as replaceable modules with standardized mounting interfaces, allowing worn parts to be exchanged without re-calibration. Junyao maintains an inventory of all wear components at its Taizhou facility and ships replacement parts to international customers within 48 hours of order confirmation.
