functions that would otherwise be accessed using dedicated control panels that serve individual railcar unloading systems, airlocks, material-routing valves, silo loaders and level sensors/monitors throughout the plant. “More and more processors are purchasing – or thinking about purchasing – resin in railcar quanti- ties to reduce material and production costs,” says Doug Brewster, Conair’s Conveying Systems Manager. “The RCU controller offers them the ability to set up and manage bulk-resin handling securely and economically, with plenty of future expansion capacity. Because it shows and controls the entire process on one touchscreen, it saves a lot of time and labour. There’s no longer any need to go outside or to manually monitor and operate a lot of dedicated equipment controls at the rail siding or at various locations in the plant. All control is in one, convenient place – indoors.” Available as a stand-alone system, or as an
easy-to-install connection for its FLX-128 Plus mate- rial handling control, the new Conair truck-fill line-proofing system safeguards the process of transferring truckload-quantity material to silos. It prevents expensive material mix-ups by remotely locking access to silo-fill lines, preventing trucks from connecting to any silo line until the correct line is confirmed and remotely unlocked by an authorized user. The new truck-fill line-proofing system consists
of a PLC module, wiring leads, and one electroni- cally-controlled interlock device per silo line. The ‘plug-and-play’ system control, which when connected directly to the FLX-128 Plus control panel, is pre-load- ed with line-proofing software. From it, power/ communications wiring extends to each of the remotely-mounted interlock devices at the end of each silo fill-line. Each provides a new 4-inch quick-connect point that is protected by a hinged, electro-mechani- cal access gate. In normal operation, the gate on each interlock device is locked by default to prevent unauthorised silo-line access. When truck unloading is required, authorised plant personnel log into the control, complete a brief list of required information for each delivery, and then select and electromechani- cally unlock one silo-fill line. Outside, at the silo location, a green indicator light indicates the open interlock. The trucker lifts the interlock gate to

open it, connects to the silo-fill line and fills the silo. When filling is complete, the trucker disconnects from the fill line and closes the interlock gate, which automatically re-locks the device. US company Dynamic Conveyor has devel- oped DynaCon conveyor systems for the plastics industry. The company says that the conveyor systems offer customisation using standard components and a variety of accessory options to create a flexible conveying system that provides easy re-configurability. Dynamic Conveyor now offers both in-line and side-by-side box filling systems by part count, cycle count or weight. All box filling systems are engineered to order to meet specific box filling needs. Systems allow user defined fill rates to ensure accuracy up to 0.3 ounces
(85 g), providing hours of unattended precise container filling. Offering a smooth transfer of boxes from 0-200 lbs (0-91 kg), the systems are automated and allow for unattended filling operation with simple control set-up and an easy to read visual indicator.
