Emerson: Accumulation belt eliminates trays under bottle packs

Using a small-pitch surface of half-inch (12.7 mm) acetal plastic rollers to provide product stability and smooth transfers, Emerson’s System Plast low-back pressure accumulation belt adds another dimension of sustainability to conveying by eliminating the need for cardboard trays under shrink-wrapped bottle packs.

The conveyor surface is specifically designed to ensure support and stability for PET bottles with petaloid bottoms, but can be used for a variety of containers. The conveyor surface provides forward movement of the product, but easily rolls under shrink-wrapped packs during accumulation, minimizing pressure on bottles at the head of the queue and eliminating the need for protective cardboard trays. Tight roller spacing eliminates gaps and provides product stability. The small pitch diameter and use of a 0.75-in. (19 mm) nose bar also allows tight end transfers.

Precision-molded premium plastics and austenitic steel retention pins maximize conveyor life and utilization, while also reducing noise.

The low-back pressure belt complements the System Plast NG chain, an advanced, low-friction flattop conveyor chain that can eliminate or greatly reduce the wasteful water-and-soap lubrication typically used in food and beverage processing. NG chain also reduces the costs and energy for water reclamation, and eliminates the wear paste buildup, noise, pulsation, and hygiene issues caused by mineral-oil based dry lubricants. Used with System Plast Nolu-S wear strips, the conveying system is said to reduce conveyor energy requirements by up to 30%, with service life sometimes as much as five times greater., according to the company.

Plant engineers can determine their own potential conveyor cost savings using a new mobile app that calculates cost reductions from various choices of motors, drives, and flat-top conveyor chains, as well as quick changeover guide rails and elimination of water/soap lubrication.
