A Zero Pressure Accumulation (ZPA) Roller Conveyor is engineered to automatically accumulate products without physical contact, eliminating back-pressure and reducing product damage. Unlike conventional powered roller conveyors that rely on a single AC geared motor, ZPA systems use individually motorized rollers in each zone. A photo sensor in each zone detects product presence, allowing precise start/stop control for smooth, efficient accumulati...
Ensures products do not collide, minimizing damage and reducing wear on both products and conveyor components.
Each zone operates independently, making system expansion or reconfiguration straightforward.
Motorized rollers run only when needed, lowering power consumption compared to continuous-drive conveyors.
Low-voltage DC motors tend to operate more quietly than large AC motors and chain-driven systems.
Each zone can accumulate or release products at the optimal time, increasing throughput and reducing bottlenecks.
Constructed from steel or aluminum profiles for structural rigidity & Designed to handle loads and maintain precise roller alignment.
Available in Roller Diameter: Typically 50 mm or 60 mm & Internal Motor: DC motor integrated into the roller tube, running on 24 VDC & Drive Heads: Double-groov...
Photoelectric (Reflective or Through-Beam) mounted at the infeed of each zone to detect product presence.
Convert 24 VDC power into drive signals for each motorized roller & Communicate with PLC/zone controller for on/off and speed settings.
Zones range from 600 mm to 1800 mm in length, depending on product size and required accumulation & Larger conveyor modules combine multiple zones, typically me...
Adjustable height and leveling feet & Rigid “H” or “C” section support legs, depending on load requirements.
Ideal for warehouse and distribution centers, ensuring gentle accumulation of small to medium packages.
Moves lightweight automotive components along assembly lines with minimal product damage.
Suitable for pallets within specified weight limits, guaranteeing no contact accumulation.
Enables buffering and sequencing of items in lean production workflows.
Streamlines order fulfillment with reduced product damage and high throughput.
ZPA Roller conveyor designed for controlled product flow without contact, featuring powered rollers, modular construction, PLC-based control, low-noise operation, and efficient automation-ready material handling performance.
