Flat Surface Labeling Machine SED-PT

Keypack Intelligent Flat Surface Labeling Machine SED-PT is an automatic top-surface label applicator engineered for precise, high-speed labeling on flat and near-flat packaging. It delivers a labeling speed of 20–100 pcs/min with a SICK photoelectric sensor and PLC-driven synchronous chain mechanism for consistent label placement accuracy. Ideal for carton boxes, pouches, bags, and flat-lid containers across food, medical, cosmetic, chemical, and electronics packaging lines.

Product Overview

The SED-PT series flat surface labeling machine adopts a mature PLC control architecture paired with a Delta touch screen HMI, enabling operators to monitor production counts, real-time speed output, and alarm prompts through a bilingual dynamic menu interface. The synchronous chain conveyor mechanism ensures smooth, bubble-free label application even at sustained production speeds. The machine frame is constructed from SUS304 stainless steel and anodized aluminum alloy, providing corrosion resistance and structural durability in demanding industrial environments.

A no-product, no-label detection function is integrated as standard: when the photoelectric sensor detects an absent product, the label feeding motor pauses automatically, preventing label waste and triggering an alarm prompt. Production counting per shift is displayed in real time, supporting capacity planning and output verification. Keypack Intelligent (kunbupack) SED-PT labeling systems are configured for straightforward integration into existing conveyor-based packaging lines with minimal footprint adjustment.

Key Features and Machine Characteristics

• PLC Control with Touch Screen HMI: Stable high-speed operation managed through a bilingual dynamic menu interface, reducing operator training time and enabling fast parameter adjustment between product changeovers.
• Synchronous Chain Conveyor Mechanism: Ensures smooth, accurate label placement across flat surfaces, reducing label skew and misalignment during continuous production runs.
• No-Product No-Label Detection: SICK photoelectric sensor halts label feeding when no product is detected, minimizing label waste and triggering automatic alarm prompts for line monitoring.
• Production Count and Speed Display: Real-time per-shift output counting and speed readout support production planning and capacity verification without additional instrumentation.
• SUS304 Stainless Steel Frame: Corrosion-resistant and rust-proof construction suitable for food-grade, pharmaceutical, and chemical packaging environments.
• Premium Imported Electrical Components: SICK sensors, Schneider safety switches, Delta HMI, and Airtac pneumatics contribute to low failure rates and stable long-term performance.

Application Areas

• Food Industry: Flat label application on snack boxes, seasoning cartons, dried food pouches, and beverage outer packaging.
• Medical & Pharmaceutical: Precise sticker labeling on medicine boxes, diagnostic kit cartons, and medical device packaging requiring consistent placement accuracy.
• Cosmetics: Top-surface labeling on skincare product boxes, gift set cartons, and flat-lid cosmetic containers.
• Chemical & Industrial: Label application on chemical product cartons, industrial component boxes, and flat-surface packaging for lubricants and cleaning products.
• Electronics: Barcode and product label application on electronic component boxes, retail packaging cartons, and accessory pouches.
