Panasonic LX-101 Color Mark Sensor – Full Industry Application Scenarios

Core strengths of LX-101: RGB triple-color light source, 1×5mm slender spot, 45μs fast response, IP67 waterproof rating, dual-mode (high-speed MARK tracking / high-precision COLOR discrimination). It adapts to working conditions including narrow color marks, transparent films, reflective aluminum foils, light marks on light backgrounds and high-speed webs. Below is a breakdown of applicable industries, 装置, working pain points and matching operation modes.

1. 包装産業 (Largest Application, 70% of Install Base)

1.1 Vertical Form-Fill-Seal Machines (Granules, Powders, Snacks, Daily Chemicals)

Working Conditions: High-speed web transport of PE/OPP composite film, transparent metallized film and matte color film; fixed-length bag cutting and vertical/horizontal sealing alignment

Pain Points: Single red-light sensors produce false triggers on transparent film, pale pink backgrounds with pale red marks and reflective metallized layers; line speed up to 150 packs per minute requires ultra-fast response

Recommended Mode: MARK Color Mark Mode (auto-selects optimal RGB light channel)

機能: Detects printed registration marks to trigger servo fixed-length cutting, eliminating uneven bag lengths and sealing misalignment; ON/OFF delay filters false triggers from film wrinkles

適用機器: Potato chip packaging, laundry detergent bags, pet food granule packs, tea pouches, non-woven fabric mask bags

1.2 Horizontal Flow Wrappers (Bread, Pastries, Tableware, Small Hardware)

Working Conditions: Continuous high-speed feed of single-layer transparent shrink film, pearlescent film and semi-transparent ink color marks

応用: Identifies edge registration marks to synchronize cutters and sealing rollers; distinguishes presence/absence of printed marks to reject blank film waste

Matching Advantage: 1×5mm narrow spot reliably tracks tiny 2mm printed marks without drift

1.3 3-側 / 8-Side Seal Bag Makers (Snack Stand-Up Pouches, Vacuum Bags)

Special Substrates: Aluminum foil composite bags, matte kraft paper composite film, pale ink light-colored marks

Pain Points: Severe aluminum foil reflection and minimal color contrast between background and marks cause frequent mark loss with standard red-light sensors

LX101 Solution: Automatic RGB channel matching; blue light suppresses specular reflection from aluminum foil for stable detection of pale gray and pale yellow marks

1.4 Labelers & Sleeve Labelers (Mineral Water, 飲料, Cosmetic Bottles)

1. Flat Labelers: Position color marks on cartons, distinguish front/back color blocks to prevent reversed labeling
2. Heat Shrink Sleeve Labelers: Locate registration marks on transparent PVC shrink film to synchronize label cutting and bottle sleeving

Recommended Mode: COLOR Color Discrimination Mode (judges via RGB ratio) to tell similar pink/red marks apart and avoid upside-down sleeves

1.5 Integrated Filling & Sealing Machines (Sauces, Beverages, Oral Liquids)

応用: Align web film for sealing and detect seal marks to ensure complete sealing; track registration marks on aluminum foil sealing film

Environmental Advantage: IP67 waterproof construction withstands mist from washers and liquid splashes, stable performance in washdown food workshops

1.6 Slitters & リワインダー (Finished Packaging Web Cutting)

High-speed web slitting: Track color marks on printed film and hot stamping film for fixed-meter cutting; 45μs response supports line speeds up to hundreds of meters per minute

2. 印刷 & Flexible Packaging Industry

2.1 Gravure / Flexo Web Printing Presses (Printed Film & 紙)

コア機能: Overprint Registration Mark Detection (multi-color alignment marks); real-time correction of printing roller offset to eliminate ghosting and misregistration

Working Conditions: Full-pattern base film with registration marks surrounded by graphics, unrecognizable by single-color sensors

Recommended Mode: COLOR High-Precision Color Difference Mode, differentiates marks from surrounding patterns via RGB ratio comparison

2.2 Paper Slitters, Hot Stamping Machines, Laminators

Detect printed positioning marks on art paper and coated paper gift boxes; identify gold marks on hot stamping film (gold reflection easily causes false triggers; RGB automatically switches to green light for reliable reading)

2.3 Adhesive Label Printing Presses

Locate tiny marks on narrow label webs to synchronize die-cutting and waste stripping; auto-sort batches of colored labels by hue

3. 食べ物 & 製薬産業 (クリーン, Humid Environments with Heavy Aluminum Foil Substrates)

Food Production Lines

1. Chocolate & Candy Aluminum Foil Packaging: Stable detection of pale gold marks on silver aluminum foil
2. Frozen Food Packaging: Operates in low-temperature workshops (-10℃ ~ +55℃ wide temp range) to read semi-transparent marks on frozen film
3. Disposable Tableware Packaging: Track marks on transparent plastic film for cutting

医薬品 & Healthcare Products (High Precision Color Discrimination for Compliance)

1. Blister Packaging Machines (Tablet Aluminum-Plastic Sheets)

応用: Sort blister packs by color blocks (Red = Spec A, Blue = Spec B, Green = Spec C) with automatic rejection of mismatched colors; locate printed batch code marks

Recommended Mode: COLOR Mode, 12-bit high precision differentiates near-pale hues to prevent product mixing

2. Carton & Ointment Tube Filling Lines: Color positioning marks on cartons synchronize carton folding and inkjet coding
3. IV Bag & Aluminum Foil Medicine Bag Makers: Track marks on multi-layer composite pharmaceutical film for fixed-length cutting
4. リチウム電池 & Optical Film Industry (For High-Reflective & Transparent Substrates)
5. Lithium Battery Separator & Aluminum Plastic Film Slitter Rewinders

Substrates: Transparent PP separators, matte aluminum plastic packaging film with tiny black printed registration marks

Pain Points: Light transmission and specular film reflection trigger frequent false signals from standard photoelectric sensors

LX101 Advantage: Coaxial optics + RGB triple-color light suppress film reflection for stable detection of 0.8mm micro marks

2. OCA Optical Film & Release Film Slitting: Detect invisible ink marks on transparent film
3. プリント基板 & 3C Electronics Automation
4. PCB Assembly Lines

応用: RGB printed marks at PCB corners distinguish board versions (Red = Version A, Green = Version B) for automatic sorting

結果: Reduced false detection rate from 12% to under 0.5% vs single-color sensors

2. Phone Protective Film & Adhesive Die-Cutters: Position marks on transparent PET film to synchronize die-cut blades
3. Wiring Harness & Plastic Housing Sorting: Differentiate clip/housing models by color to divert defective products
4. Daily Chemical, 化学薬品 & Non-Woven Fabric Industry
5. Non-Woven Mask Bag Makers: Light base non-woven fabric with pale pink printed marks; MARK mode auto-selects optimal light channel for recognition
6. Laundry Detergent & Cosmetic Hose Extruders: Track marks on printed hose web for cutting
7. Fertilizer & Chemical Powder Packaging: High-speed detection of black marks on thick matte woven film
8. Specialized Working Conditions Unique to LX-101

7.1 Light Marks on Light Backgrounds (Most Challenging Condition)

Off-white film with pale yellow marks, pale pink base with pale red marks lack sufficient contrast for single red-light sensors. LX101 automatically switches to blue/green light channels to boost signal-to-noise ratio for stable output.

7.2 High-Reflective / Metallic Substrates

Metallized film, aluminum foil, hot stamping foil, bright silver PET film suffer severe specular reflection interference. RGB algorithm filters specular reflection and only responds to ink color differences.

7.3 透明 / Semi-Transparent Film

PVC shrink film, transparent food film, lithium battery separators transmit light and produce no signal on standard photoelectric sensors. Overlapping RGB light sources capture ink absorbance differences to detect invisible registration marks.

7.4 Tiny Narrow Color Marks (1~3mm Width)

Exclusive 1×5mm slender rectangular spot avoids accidental reading of surrounding background; ideal for narrow labels, small blister packs and miniature electronic films.

7.5 Humid Washdown Workshops

IP67 protection eliminates the need for extra protective covers in splashing, misty and dusty environments; direct installation in food and pharmaceutical clean rooms.

7.6 Multi-Color Sorting to Prevent Product Mix-Up (Exclusive to COLOR Mode)

Automatic sorting of multi-hue products on a single line: red-labeled goods route to Line A, blue-labeled goods route to Line B; RGB ratio precisely distinguishes similar hues.
