A large material handling systems integrator in the Midwestern U.S. had a customer that was experiencing difficulty along their 24V powered roller conveyor system. Needing a solution that could eliminate this from continuing in the future, the industrial supplier turned to a systems integrator and Comtrol’s IO-Link Master.
The customer is a large industrial supplier and uses small and large plastic totes to transport material throughout their factory. At specified locations along the line, the totes are empty and need to be moved to a stacker machine. Occasionally these totes entered the stacker machine with material left inside, causing it to jam and interrupt production.
The system integrator opted to implement a solution using Comtrol’s IO-Link Master DR-8-EIP to control Leuze Electronic IO-Link enabled light curtains and laser distance measuring sensors. Now as the totes pass along the conveyor line the light curtains, located along the side, determine how the totes are stacked. This information is then relayed through the IO-Link master to the Rockwell ControlLogix Programmable Logic Controller (PLC). The laser distance measuring sensor, found above the conveyor line, scans the inside of the totes for material left inside. When the tote is emptied, it proceeds along the line and is stacked by the stacker machine; if the scanners determine there is any material left inside the tote, it is not stacked and is sent to a rejection area. As a result of this implementation, the industrial supplier has increased efficiency and prevented potential damage to their stacker machines.
