Accumulating conveyor belts can be slowed/stopped, allowing products to be consolidated. With each roller touching, a single driven roller can supply power to the rest of the conveyor.
Used accumulation conveyor manufacturers include Buschman, Mathews, Rapistan, and Speedway. American Surplus stocks these brands along with Hytrol, Ermanco, ACSI, and Interlake. Design and installation of used belt over roller conveyor, by trained professionals, is available nationwide.
Accumulation conveyors contain rollers to transport product, and are typically part of an entire conveyor system. They consist of pop-up sensors that hold product in place on the conveyor line until the next section is clear. Once the next section is clear, the sensor receives a signal and releases the product. This is extremely useful when you need to transport products onto a case sealer, sortation system, weigh station, or any part of the system that requires each product to be handled individually.
The two main types of accumulation conveyor are zero pressure and minimum pressure. As stated above, zero pressure does not allow products to touch when being transported down the conveyor line. This is useful when you have fragile product that could be easily damaged, scratched, etc. if it were to make contact with another. This style will stop individual zones when the leading zone still contains a product, and then will proceed when that product is free from the leading zone.
Minimum pressure allows for products to touch but does not allow for back pressure buildup. The amount of back pressure can be set and is usually around only 2% of the total load being carried on the conveyor. This is made possible through use of a spring adjusted carrier, which can sense the driving friction required to maintain movement without accumulating pressure.
Why buy used accumulation conveyor? Conveyor can be very expensive to buy new, and intimidating to buy used because you may not know exactly what condition it’s in. Here at ASI, we specialize in used, and each unit is hand inspected, tested, and cleaned prior to shipment. We guarantee our conveyor will work upon arrival (exclusive of freight damage). We also provide installation services to ensure that your conveyor system is installed and functioning properly.
