简体中文 First, the basic question: why the turning conveyor can determine the production efficiency?
Goods stuck in bends in factories, roller strikes every three days, maintenance costs higher than the electricity bill - these problems are all directly linked to the layout and maintenance of the turning conveyor! It is not just a "cornering tool", but aThe core of space utilisationrespond in singingtrouble spot. A proper layout can save 30% of workshop space, and proper maintenance can double the life of the equipment.
Second, the scenario problem: how can the layout be such that the turning conveyor is not blocked or overturned?
1. Turning radius is not selected correctly, the goods will be "flung away" in minutes.
- The formula must be memorised.Minimum radius ≥ 1.5 times belt width(e.g. at least 900mm radius for a 600mm wide belt). Radius too small? Cartons crushed into waste paper balls, metal parts cratered.
- Special materials to be added: Fragile glass recommendationsRadius ≥ 3 times widthBags of flour have to have extra baffles to prevent spills.
2. The angle of the turn hides a deadly trap
- A 90° right angle turn is the "hardest hit by rollovers".! Switch to30°-45° angled turnsThe cargo centrifugal force is 60% straight down.
- The exception to the forced sorting scenario: U-bend with sensor + guide arm, 90° instead for accurate parcel diversion.
3. Space draining: turning dead corners into golden passages
- "S-shaped" layout saves more land than "U-shaped" 40%: Food factories use this trick to cram six production lines into a 200m2 workshop.
- Cubic transformation: the upper conveyor makes a 15° inclined turn and the lower one returns to the flow line, a height difference of 1 metre is enough.
Third, the solution: maintenance to do a step wrong, the loss of 100,000 to start!
▶ Fatal mistake 1: The chain is "too tight" or "loose".
- Golden sag range: 6.5-25.4mmGet a ruler! (Take a ruler and measure!). If it is too tight, it will pull off the core, if it is too loose, the chain will jump the teeth and jam the whole line.
- Practical test method: index finger presses the middle part of the chain, subsidence3mm like a pressed eraserThe touch is just right.
▶ Fatal Mistake 2: Spraying oil indiscriminately into the bearings
- Food factory fiasco: motor oil mixed with flour dough, whole batch scrapped!Food grade grease refilled every 500 hoursThe oil filling hole has a special sealing cap.
- For non-food linesLithium grease antiwear oilThe use of used engine oil is prohibited - it sticks to the dust and becomes "sandpaper", and it only takes 3 months for the drum to wear through.
▶ Fatal Mistake #3: Waiting to Replace Parts Until They're Broken
- Wear and tear three-piece mandatory inspection cycle::
parts Detection tools Replacement Criteria Roller bearings medical device listen to heart rate Discontinue use immediately if the noise level exceeds 70 dB covering layer dial calipers Thickness <2mm must be replaced sprocket tooth electric hand torch Missing teeth > 2 or reverse teeth - The real lesson: an auto parts factory to save 200 yuan sprocket, the results of the chain collapsed and crashed laser equipment, repair costs 120,000 yuan.
Fourth, to avoid the pit guide: these "save operation" are all mines!
► "Variable frequency speed control is unnecessary?" -- Look at the material to determine life and death!
- Electronic chips must be usedFrequency converter speed control at 0.3m/sOtherwise electrostatic breakdown;
- A fixed-speed motor is adequate for hardware parts, butYou've got to slow down 30% on a slope turn.Otherwise the nut rolls all the way down the groove.
►"Anti-skid baffle randomly installed?" --Wrongly fitted to become a "blocking device".
- The gap between the baffle plate and the conveyor belt > 5mm: small screws directly leak out (a mobile phone factory daily loss of 2000 screws);
- Correct mounting.Baffle height = material height 1/3, spacing ≤ minimum part size.
►"Stainless steel equipment once and for all?" --Chemical Workshop Anti-Corrosion
- 304 stainless steel for chlorine environment? Rust through in half a year! You have to use it.316L stainless steel + Teflon overmoulding.;
- Carbon steel galvanised is adequate for ordinary warehouses, butWelds to be galvanised twiceOtherwise the weld rots through first.
Editor's ten-year blood and tears summary.
Layout remember "oblique angle priority, radius 1.5 times the jump", maintenance keep a close eye on "chain sagging 3mm, bearing no sound to qualify". Don't believe in the myth of "no need to maintain the equipment"...Save an hour of maintenance and a full day of line downtime.I've seen too many cases of this!
