Zero-line pressure conveyors work without contact

A major design plus for the latest zero-line pressure roller conveyor from Excel Automation is the inclusion of a miniature 24Vdc drive and associated gearbox within one of the actual conveyor rollers

This enables a compact, low-power accumulation conveyor to be built that is ideal for conveying unit loads such as cartons and totes for many industry sectors including the food and beverage industries, high-speed warehousing and distribution centres.

The drive of this self-contained, modular accumulation conveyor system will typically drive up to nine slave rollers to create a single zone through a simple loop configuration that is capable of operating at speeds up to 90 metres/min.

However, to cater for application variations Excel adapts each zone size by adding or reducing the number of rollers to suit tote bin/carton length as well as adjusting speed, although this latter adjustment can be easily carried out on site.

As the conveyor description suggests, zero-line pressure allows the accumulation of cartons and tote bins in each zone without collision and rubbing, thus preventing damage to the outer wrapping in the case of a carton or parcel.

Control is achieved by a single photoelectric sensor strategically positioned between rollers at the start and end of each zone.

It detects the leading edge of a carton, halting progress until the zone immediately in front is totally clear of its load.

This latest development affords the user many benefits including quieter operation than conventional line shaft conveyors and lower power consumption and extended longevity since the motorised rollers only run when required.

Also the build is very much in the vogue of the established Excel Excelvayor range of conveyors.

The new accumulation section embodies all the proven maintenance features such as clear side guards for visual inspection of drive cards and a simple roller removal system comprising spring loaded rollers.

Therefore in the unlikely event that a roller needs changing, even if it's the drive roller, this can be achieved without major disruption to the workflow.
