Air Conveyors for Plastic Bottles
Some plastic manufacturers use air conveyors to move plastic bottles from one place to another. These systems are ideal for use with plastic materials, because plastic bottles and containers are lightweight. They can also travel easily through tubes, which most air conveyor systems use. Some air conveyor manufacturers create conveyors designed specifically for use with plastic materials, making design adjustments that facilitate the movement of lightweight plastic as opposed to loose materials like grain or pellets.
Plastic air conveyors were first invented in the 1980s. These original systems were used to move empty plastic and steel containers from one place to another and were often used in recycling centers. Today’s modern plastic air conveyors mainly move plastic bottle caps and empty plastic bottles from one place to another.
The modern version of a plastic air conveyor moves the bottle through the conveyor by the neck, rather than from the bottom. These neck conveyors apply lift pressure on a strip of plastic around the bottle’s neck, lifting the bottle into the air using the same physics technology as airplane wings. This allows the bottles to propel through the tubes faster than if other conveyor systems were used. This technology also uses less energy than other air conveyance systems. Every so often along the tube line, the tubes are filled with an additional burst of air to propel the bottles faster.
Very little power is necessary to propel the bottles used in neck conveyor systems due to the natural lift occurring with the flow of the air around the neck of the bottle. Bottles can travel around 300 feet using this conveyor system, which is farther than many other types of plastic conveyors.
