Interroll Control and Drive Includes Pallet Conveyance Solution

Interroll is expanding its decentralized control and drive concept, which has been used successfully for years with the Interroll 24V DC RollerDrive and the Interroll MultiControl for zero-pressure unit load handling. Now, the portfolio also includes a special solution for pallet conveyance.

The Interroll Group, a global provider of material flow solutions, now also enables zero-pressure pallet conveyance. The new Pallet Control 6000 control unit, available now, is a key component of the complete solution, which also includes the conveyor rollers, the MultiControl and the Interroll Pallet Drive. It allows the use of 400V AC drive technology.

This new solution makes uninterrupted, trouble-free material flow much easier to achieve: Until now, zero-pressure pallet conveyance usually involved great costs using programmable logic controller (PLC) software and additional pneumatics to ensure an automated flow of goods at the transfer points to, for example, the stacking machines or lifts in the warehouse. However, the solution from Interroll eliminates the need for centralised PLC cabling and PLC programming. The new control unit serves as a link between the drive and Interroll’s proven MultiControl, which again provides the complete logic for zero-pressure conveyance.

A pallet conveyor using Interroll technology is energy-efficient as it is not under continuous operation. Rather, it can be split into different zones, which are able to activate and deactivate automatically, as and when required. This offers the benefit of only using energy when material is actually being conveyed by the system. So, the only pallet drives activated at any given time are those that are currently required to enable the optimum flow of pallets. The integrated soft start function reduces the starting torque, which relieves the load on all mechanical components, thereby providing for optimum pallet acceleration. Pallet overrun after the Pallet Drive has been switched off is also regulated by Pallet Control.

Another benefit of this solution is its compact nature: As a drum motor, the Interroll Pallet Drive has the same dimensions as the conveyor rollers used. It can, therefore, be seamlessly integrated in a conveyor profile. This means that the drive station requires no extra space, and the conveyor can be fitted directly on the floor or integrated in a turntable. Compared with solutions using an external gear motor, this represents significant space savings.
