Unicon VVESS (steel roller type)
Zero pressure accumulation conveyor (for heavy loads)
A completely zero-pressure conveyor that can safely store materials temporarily. It has a built-in control function that accumulates materials by zone and delivers them at a pitch. Ideal for transporting food containers.

- 1) Stopping accuracy varies depending on speed and transport conditions. Please contact our sales department for details.
②The power switch is installed only at the most downstream point.
The drive is linked with a ribbed belt for powerful transport. The maximum transport weight per zone is 80 kg.

Estimated transport weight for each zone

Zero pressure accumulation/pitch payout
Because transported items are stored in zone units, zero pressure accumulation is achieved with a gap between the items being transported in front.
When a discharge signal is issued, the items are discharged sequentially, maintaining a distance from the leading item.
