Imagine - hundreds of pounds of car axles in the workshop clattered to the ground, workers pushing a trolley downhill was almost brought over ... this scene in the traditional automotive plant is not particularly common?Manual handling is slow and dangerous.But what about a normal conveyor belt? The axles get deformed in the middle.How can we design this "iron lump" to run safely and efficiently?Today we use the vernacular to dismantle the core doorway of this system, especially for newcomers to the white, read the end of the guaranteed that you can understand the "re-distribution" and "security" of the two major lifeblood!
First, the axle conveyor line for what must be "heavy dispersion" can not?
The axle is not an ordinary part, often hundreds of kilograms of weight, if the conveyor belt like the courier conveyor belt is laid flat to transport, the middle of the overhanging part of the conveyor belt will be crushed in minutes. The patent document mentions a trick.Replacing traditional belts with roller arrays, allowing the weight of the axle to be spread over dozens of support points. How exactly does that work? Look at these three points:
- relay race on wheels: Each section of the roller only carries a local weight, like multiple people carrying a sedan chair - you carry the front, I carry the middle, he holds the rear, no one eats the weight;
- borrow borrowed strength from a slope (idiom); to use a fair amount of strength to get what one wants: Design of angled transport sections (called "downward sloping transport sections" in the patent) that allow the axle to slide under its own weight, saving power and reducing wear;
- anti-slip insurance: Add non-slip washers on the surface of the rollers to prevent the axle from slipping and "skidding".
To cite a chestnut: a production line measured, the single point of load-bearing changed to 15 roller dispersion, equipment life from half a year to 3 years! This investment is absolutely worth it.
Secondly, security protection: it is not enough to stop the machine, but to "prevent stupidity and dullness".
Newbie most afraid of equipment out of control injury? Look at the axle line "triple protection logic":
(1) Mechanical defence: physical interception
- Baffle + Foam Pad: The end of the conveyor line is fitted with a baffle and sponge is attached to the inside - equivalent to a car bumper, so there is no fear of bumping into it (the patent mentions that it can reduce the length of the buffer section and save space!) (the patent mentions that the length of the buffer section can be reduced to save space!
- Chain catcherIn the unlikely event of a sudden breakage of the towing chain, the catch in the ascending/descending section immediately locks the frame and prevents a "bridge fall".
(2) Electrical Emergency Stop: Second Response
- Safety light curtains: Like the underground security gate, once a person breaks into the infrared sensor area, the motor immediately cuts off the power;
- Dual button emergency stop: Critical workstations are equipped with parallel emergency stop knobs, shooting any one of the whole system shutdown.
(3) Intelligent identification: separation of people and goods
This is particularly advanced! For an electronics factory programmeSafety light curtain + sensor combinationIt automatically distinguishes between people and goods:
- Cargo over - light curtain release;
- Human break-in - shutdown in 0.1 seconds.
Why does it have to be different? You can't stop production every time a forklift goes by, can you? This system is the perfect solution to the conflict between efficiency and safety.
Traditional manual vs automated conveying line comparison table
| comparison term | manual handling | Automated conveying lines |
|---|---|---|
| efficiency | Carry 20 in an hour | 120 per hour(6-fold increase) |
| Risk of injury at work | High prevalence of pushchair falls and lumbar strain injuries | near-zero risk(triple protection) |
| space occupation | Manual access required | three-dimensional transportProvincial 30% |
| (manufacturing, production etc) costs | Ongoing expenditure on human wages | Payback in 3 yearsLow post-maintenance |
IV. Self-questioning: 3 core questions most frequently asked by white people
Q1: What should I do if my axle gets stuck in a turn?
A: There's a great trick hidden in the patent - turn section setupsDouble tensioning wheelIt's like a "chain keeper"! It acts as a "chain keeper", always keeping the chain taut to prevent slipping and sliding. What's more, the spreader has rubber pads on the contact surfaces to prevent scratching the axle surface and increase friction.
Q2: Should the conveyor line be stopped when the robot is spraying?
No need! Paint line case byPrecise calculation of chain speed and pitch(For example, if the axle is 2.2 metres long, leave 0.8 metres of space for the robot to work), allowing the axle to pass through the gun zone at a constant speed without affecting continuous operation at all.
Q3: Does a sudden power failure skid the car?
Early defence! Heavy hammer tensioning device + electromagnetic holding brake double insurance, power failure instant automatic locking drum - as stable as the principle of lift emergency stop.
Editor's view: figure out the axle conveyor line actually grasp two points -Making weight "rain on the parade"(roller dispersion + ramp design).Security as "OCD."(Mechanical interception + intelligent recognition + emergency stop redundancy). Do not think that this is the engineer's business, production line supervisor according to this logic to accept the equipment, the failure rate can be cut in half! By the way, if a novice wants to quickly master, it is recommended to go to the workshop to touch a roller non-slip pad, which is more useful than reading 10 pages of documents. Next time, we will talk about the "accumulating roller" - can make the axle queuing for processing of the god operation!
