简体中文 Newbie white first design conveyor line, is not staring at the turning radius parameters a face confused? Why is it that other people's goods turn as steady as a mountain, your box always in the corner ”drift”? Don't panic! Today we use the vernacular to dismantle this puzzle---Choose the right turning radius and runaway problems can be reduced 70%!
First, the radius is not selected correctly, the goods become ”bumper to bumper”.”
Here's the core conflict.: Turning radius is too small, cargo inertia, directly thrown away; radius is too large, and a waste of space to burn money. How to break? Remember this life-saving formula:
Minimum turning radius ≥ 1.2 × cargo length(e.g. 800mm box with a radius of at least 960mm)
In practical engineering, the radius is usually divided into three grades:
| Cargo length (mm) | Recommended radius (mm) | Applicable Scenarios |
|---|---|---|
| ≤500 | 600 | Small electric box, parts box |
| 500-1200 | 900-1200 | Standard logistics boxes, medium-sized equipment |
| >1200 | 1500-3000 | Large pallets, machinery and equipment |
(Data source: industry generic design codes)
lesson learned through blood and tears: a factory hard to 1.2 meters long mold into the 900mm radius, the result is that every turn jammed machine -The money saved on the radius pays for all the repairs!
Second, anti-running ”black technology” are in the details
Why are you running away when you have enough radius?The key is in the ”careful” design of the drum.::
-
Taper roller is the soul
Why do rollers have to be tapered? Simply put:- Inside drum turns slowly (small radius)
- Outer drum turns faster (larger radius)
Taper α = arctan(width/2 x radius)The control is usually in the range of 1° to 5°.
give me an example: 1200mm radius for a conveyor line with a width of 1 meter and a taper of ≈ 2.4° is the most stable.

Comparison of three major anti-bias devices
anti-bias measures (manufacturing, production etc) costs corrective force Scenario Bi-Taper Roller 中 ≥30N/m Conventional cartons, plastic crates Dynamic Guide Wheel 高 50-200N Precision instruments, glass products Magnetic guiding system extremely high 0.1-0.3T Thin steel sheets, solar wafers (Source: Machinery)Anti-offset designStandard)

Control System ”Troubleshooting”
- Speed Closed Loop: Inner and outer motor speed ratioKv = (outer radius/inner radius)
- pressure sensitive: 4 sensors per square meter, real-time speed adjustment
- visual deskew: 5000 fps camera grabbing offset, auto-correction within 100ms
Third, the white selection of three steps to avoid the pit guide
Once you understand the principle, do this in practice:
-
Ask yourself four questions first
- What kind of cargo? →Length, width, height + weight(Soft bags must be palletized!)
- How harsh is the environment? → Stainless steel for humidity, heat-resistant steel for high temperature
- How fast does it have to be? → Formulav ≤ √(0.4 x 9.8 x radius)anti-dumping
- Frequent deflection? → Frequent deviation directly on the double taper + guide wheel combination
-
Three details to die for when installing
- Roller spacing ≤1/3 cargo length(Ensure that 3 rollers are always available to hold the load)
- For bearingsIP67 protection rating(Dustproof and waterproof, double the life span)
- Power on first run 72 hours without load (ISO 20278 standard test)
-
Maintenance Money Saving Tips
- Monthly plusFood Grade Grease(Graphite grease for high temperature environment)
- Soft goods are cleared every week.Roller ResidueUse a nylon scraper, not an iron brush.
- Quarterly schooltaper angle(Immediate adjustment for errors exceeding 0.5°)
Fourth, the soul torture: how to break the special scene?
Q: How do I turn a 5 meter long steel pipe?
→ Segmented differential speed control! Speed gradients every 30° with dynamic support beams in between
Q: What should I do if I am afraid of bumps in soft tofu products?
→ polyurethane roller (hardness 50-60 Shore D) + speed limit 0.5m/s
Q: Will the spiral climb turn over?
→ Rise angle θ ≤ 15°! FormulaH=v²×tanθ/gCalculate the safe height
Editor's point of view
Ten years.Conveyor line designI've seen too many people blindly copying programs and flipping--Turning radius is not ”just about right” at all!The next time you make a selection, pull out your cell phone and cross-reference the formulas and tables in this article, and save enough money on repairs to buy ten cups of milk tea. Remember: the heart of runaway prevention isMake the cargo like a high-speed railroad ride through a curve, not a roller coaster!
