Double-deck Speed Chain Conveying: A New Paradigm for Spatial Reconfiguration and Intelligent Conveying

▍核心原理：差速效应与垂直循环的精密耦合

双层倍速链系统的本质在于​Co-evolution of physical speed-up and spatial reuse​。其核心原理基于滚轮（直径D）与滚子（直径d）的直径差异：工装板的实际速度由链条整体移动速度（V₁）和滚轮自转产生的附加线速度（V₂）叠加而成，遵循公式 ​Vtooling board
= Vsprockets
× (1 + D/d)​。当D=2d时，工装板速度可达链条速度的3倍（即三倍速链）。

  • ​upper chain of productionConveying of loaded pallets at multiplied speeds (2.5-3 times) in the range of 2-20 metres/minute;
  • ​Lower empty board return channelSave 58% horizontal space by forming a closed loop between the load shifter and the jacking mechanism;
  • ​Vertical Circulation ModuleSeamless "conveyor-return" to avoid the time-consuming problem of off-line turnover of tooling boards.

​personal viewpointThis design is actually an industrial expression of "space-time compression" - reconfiguring the production line through physical structures. For example, in a 24-metre production line in an automotive parts factory, the structure reduces assembly man-hours by 351 TP3T, demonstrating thatThe multiplier effect of space efficiency on manufacturing effectiveness.
