Features Of Accumulation Conveyor Systems

An industrial conveyor has a feature called the accumulation system which helps in keeping a merchandise in place until it is required to be released. Applications include feeding product to your machine such as a case sealer in a specified rate, or to hold all items to be sent on a truck that is given until that truck is prepared to be loaded. It works with one or more “stop” zones which briefly delays the product movement.

Accumulation systems come in a wide selection of sizes and shapes, in the simple to the highly advanced. But they all are basically geared towards an individual aim to stop products from ‘falling off’ the end of the conveyor and in exactly the same time allowing free motion of these products near the ‘beginning’ of the conveyor.


In it’s simplest form, a belt conveyor may possess a small span of powered gravity rollers. The movement of the products is temporarily stopped after the belt is moved down. Products that are following arrive and’ push ‘ the primary product further down the roller region.

Products stack up in the accumulation place till there is no space left for ANOTHER merchandise, as the above procedure continues. In this scenario one more sensor can be incorporated to stop the whole system once the accumulation area is ‘complete’.

A more advanced accumulation system is a powered roller conveyor whereby each roller has a sliding clutch. The product stops as it reaches the end of the conveyor, from moving forward. Friction between the stationary product and also the turning rollers beneath it causes the roller clutch to slip, and the roller stops turning. This mechanism makes the system flexible and the conveyor practically functions as an automated accumulation zone.

Accumulation is similar to electricity roller conveyors with exceptions that are important. The drive pressure on the product eliminated altogether, or even can be fixed to a minimum. This is useful when a long line of cartons need to be accumulated without pressure so they may be used in a procedure like deciding, sorting, taping, strapping, palletizing, or loading.

Minimal pressure accumulation conveyors allow products to softly touch while being carried. Package damage is prevented by minimal back pressure, although the conveyor can block the movement of the product.

In zero-pressure accumulation, each other do not touch and put no force on product when it stops. By placing sensors at regular intervals, drive pressure is removed. Each zone extracts electricity from a flat drive belt that runs the entire length of the conveyor.

The detector eye is activated when a product is ceased and sends a signal to the immediately preceding zone as. The drive belt is lowered from the tread rollers causing the product before the item is released to stop when the next load moves into this zone. The remainder waiting in line behind this zone will sequentially move forward, as any merchandise is removed.
