Multi-Conveyor recently built this multi-sectional stainless steel, wash-down rated, 24VDC MDR (motor-driven roller), conveyor system for a food application. The system is a combination of straight running and curved MDR with an incorporated 90° case turner and pop-up reject section.
The customer required maximum product flow control. Multi-Conveyor’s electrical team used photo eyes and reflectors across incremental targeted locations to precisely detect and engage product stop and start motion.
In the video, Multi-Conveyor removes one box of product to show how the system senses the opening, then triggers prior sections of MDR to activate and move the product forward to close the gap. Likewise, the guide rail prevents the product from going beyond the conveyor frame – providing even more control.
24VDC power supplies and drive cards are housed in stainless steel boxes mounted on the roller conveyor frames. Each drive card controls two drive rollers – one per section. The drive cards operate using standard accumulation logic, allowing the conveyor zones to remain full during production.
A seamless transition transfers boxes from the roller section to a 90° dual strand or dual lane case turner. Opposing belt speeds rotate cases to be accepted into an elevator ahead where cases are lifted onto a palletizer (that section is not shown).
NOTE: Multi-Conveyor does not build gravity roller or stationary roller systems. They specifically build custom, wash down, or sanitary 24VDC motor-driven roller systems on an individual project basis.
