Ljxy automatic roller conveyor line selection South: 10 meters within the intelligent logistics design points

​4 core parameters for drum selection​

​1. Principle of matching length to load bearing​

  • ​Roller length= Cargo width + 50-100 mm (refer to pages 1 and 5), reduced to 80% width for cargo with high rigidity of the bottom surface.
  • ​Load-bearing calculations: Single drum load = total weight of the goods ÷ number of contacting drums (≥ 3), e.g. 300 kg of goods requires at least 5 drums with a weight of 60 kg (page 5).
  • ​Wall thickness and shaft diameterCarbon steel galvanized drum wall thickness ≥ 2mm can carry 50kg, stainless steel needs to be ≥ 1.5mm (page 5)

​2. Material SelectionScenario-based decision making for​

environmental needs Recommended Materials Disable Scenarios
Regular dry environment Carbon Steel Galvanized Lithium battery workshop (zinc ion contamination)
Corrosive environments 304 stainless steel Cost-sensitive projects
Food/Pharmaceuticals Food Grade PU Covering Rubber High temperature >50℃ environment (adhesive layer aging)
noise reduction and anti-slip PVC rubber sleeve (gray) Oily environment (friction failure)

​3. Comparison of the economics of drive modes​

  • ​O-Belt Drive: Cost reduction of 40%, but single point break requires full line shutdown (page 5)
  • ​Multi-Wedge Belt Drive: 3 times higher transmission torque for high-speed sorting lines up to 10 meters (page 5)
  • ​chain pulley drive: Preferred for 10 m long lines with tensile strength up to 2000 N (pages 2, 11)

​3 technical points of design within 10 meters​

​Pain point 1: Insufficient tensile strength of chain leads to chain breakage​
prescription: AdoptionDouble sprocket design + 25.4mm chain pitchExtension of single line limit from 8 to 12 meters (web page 2 measured data)

​Pain point 2: Inefficient multi-directional triage on small sites​
Innovative programs：

  • ​30° conical roller: Turning radius compressed to 600 mm (pages 4, 9)
  • ​Accumulation roller technology:: Increase in stacking density by 50% and reduction in buffer segment length by 2/3 (web pages 1, 11)

​Pain Point 3:Intelligent Sorting Systempoor compatibility​
Integration key：

plaintextmake a copy of
Photoelectric sensor → PLC control box → frequency conversion motor
(Pitch 1.5m arrangement) (Response speed ≤ 0.1s) (Speed regulation range 0.3-2.5m/s)

​3. Food packaging line upgrade pitfalls​

Guide to avoiding the pit：


    

  • ❌ Ordinary rubber-covered rollers are prohibited (contamination by falling chips) → ✅ OptionalFDA Approved PU Rubber Sleeve​
    • 

  • ❌ Avoid spring-loaded press-in installations → ✅ UseThrough-axis pinhole typeAnti-bacterial design (pages 4, 5)
    • 





​The life and death of installation and maintenance​


​fatal error: Miscalculation of spacing


    

  • Formula.P ≤ 1/3 cargo length(Page 5), 1.2m standard box needs ≤400mm spacing
    • 

  • Consequence: elevated risk of box denting at spacing >500mm 70%
    • 



​Tips for Extending Your Life::

The author's personal experience: a factory due to neglect the low-temperature brittleness of stainless steel roller (-15 ℃), the winter fracture rate increased 90%, replaced with carbon steel hard chrome plating after the failure to zero.The environmental suitability of the material is more important than the priceThe




​final torture: Does your conveyor line really need 10 meters?

The empirical measurements show that.8m single line + 2m 45° diagonal railThe combination of the 10-meter straight line solution is 22% more energy efficient than the 10-meter straight line solution, and the space utilization rate has increased by 15%. The essence of intelligent logistics is not the extension of machinery, but the revolution of exchanging space for efficiency.
