Automated Line Speed Chain: The Conveying Lifeblood of Smart Factories

II. Key technological breakthroughs in whole-line integration

​Modular architecture: from stand-alone to system synergy​

A typical multiplier chain line consists of five major modules:

1. Driving section: three-phase geared motor (IP65 protection) + frequency converter, speed range 2-20 m/min.
2. Conveyor section: aluminium profile guide rail + composite roller chain, single section up to 40m long.
3. Positioning module: pneumatic stopper (±0.5mm accuracy) with photoelectric sensor.
4. Load transfer module: jacking leveller/translator to realise cross-line transfer.
5. Control centre: PLC (Mitsubishi/Siemens) with integrated RFID traceability system.

​The Hidden Costs of Being Overlooked::

​Space utilisationDouble-layer recycling design reduces the production line footprint by 38%, with an annual value-added of ￥12,000 per square metre of plant.
​Losses from downtime: Intelligent prognostic system reduces fault response timeframe from 8 hours to 30 minutes, reducing downtime losses by $2.7 million annually


Ask Yourself: The Three Laws of Multiplier Chains

​Q1: How to solve the efficiency loss of right angle turns?​

-Vector compensation + thermal deformation cancellationDouble-barrelled:

① Pre-acceleration section: 15% photoelectric triggered speed increase 3 metres before the turn

② SMA Shape Memory Alloy Guide Blocks: Automatic contraction to compensate for clearance during thermal expansion.

The measured steering efficiency of a power plant reached 97.3%, an increase of 40% compared with the traditional solution.


​Q2: How can old production lines be intelligent at low cost?​

​Three-step incremental pathMore pragmatic:

①Perception Plus: RFID read-write (¥ 3000 / Taiwan) + work board labelling (¥ 20 / piece)

②Control upgrades: Edge computing module parsing data, replacing some PLC functions

(iii)Energy recoveryRegenerative braking device intercepts steering kinetic energy, saving 180,000 kWh of electricity per year


​Q3: How to combine flexibility and stability in the whole line?​

​Modular design + dynamic dampingis the key:


Quick release guide blocks (changeover time <15 minutes) to accommodate process changes
Hydraulic cushioning system injects damping fluid during the start/stop phase, heavy load impact force attenuation 40%

After the application of a new energy battery factory, the product changeover time is shortened by 76%


I realised when a car company used digital twins to predict failures 48 hours in advance.The ultimate value of the speed chain is not only the handling of materials, but also the spatial algorithm that reconfigures production relations... MIIT 2025 data shows that factories with intelligent multiplier chain systems have a capacity density increase of 32%, but at 1/5 the cost of robotic production lines - revealing a counterintuitive truth.On the way to upgrading the manufacturing industry, the "intelligence of the basic conveyor line" has more leverage than the "humanoid robot".In the next three years. In the next three years, with the integration of bio-based nylon chain (50% raw material from waste) and edge computing, perhaps every metre of chain will evolve into a "breathing industrial nerve endings". When Germany's Bosch Lab uses SMA alloy to achieve self-regulating guidance, the winner of Made in China may be.Replacement of time costs with space efficiency, so that each square metre of plant to create more than ¥ 12,000 annual output value-After all.The real battleground of the factory is not in the number of devices, but in the efficiency revolution in the millimetre conveying gap.
