New ERT™250 Conveyor Provides Unique, Beltless, Zone Control for Pallet and Tray Handling

 

Need a pallet handling conveyor capable of zoning for accumulation and automation assembly applications? Then you need the new Edge Roller Technology (ERT™250) conveyor from Dorner.

As implied by its name, the ERT250 uses rollers to move pallet conveyors smoothly with no friction (a byproduct often seen in belt-driven platforms). The conveyor’s open design eliminates concerns of small parts or screws dropping into rollers and causing conveyor damage or jamming.

The ERT250 is ideal for applications calling for pallet or tray handling; no- and low-back pressure accumulation; medium to heavy load assembly automation; and Cleanroom applications such as medical product or device manufacturing, assembly, packaging and others.

The rollers are driven by a patent-pending, energy efficient linear gearbox that gives customers added flexibility with motor positioning and zoning. This allows for zone and slip roller operation. Simply removing a lower gear creates independent zones.

The non-contact zone control provides simplified traffic control that eliminates pallet stops and costly pneumatic valves. Conversely, slip rollers can be used for full length runs with conventional pneumatic pallet stops. The rollers are easily accessible and can quickly be replaced without affecting the remaining portion of the conveyor.

Technical specifications of the new ERT250 include:

  • Widths 120 mm to 960 mm wide
  • 38 mm diameter rollers on 50 mm centers
