NPE2018 New Technology Focus: Resin Conveying

From RFID couplings to 'Wave' conveying, material is moving smarter at NPE.

Options for moving materials to blenders and processing equipment are getting smarter at NPE2018. Motan’s MetroConnect U/C manually operated coupling system for pneumatic conveying lines offers an RFID option for error-free connections. MetroConnect C (for “coded”) represents an RFID enabled system. Motan notes that an uncoded MetroConnect U or legacy system (Motan or otherwise) can have the RFID capability added. Motan says that coded coupling stations not only prevent coupling errors, but in certain fields, they are necessary if material tracking, validation or certification is required.

The coupling system is controlled, monitored and configured with the MetroConnect controls. Up to eight blower lines can be set up with a maximum of 96 loaders and material sources. Up to 125 coupling points can be connected to each blower line. If required, an extension of up to 250 coupling points is available.

Maximum flexibility is the goal of a new discrete wired conveying controller that allows the number of pumps and receiver stations to be customized to fit processors’ evolving needs. AEC’s VacTrac Plus can control vacuum receivers, vacuum pumps, remote proportioning valves, purge valves, knife gates, and pump or hopper blowback in any resin conveying application across any process. The control is fully configurable from one to 12 pumps and one to 44 stations.

The VacTrac Plus has a 7-in. color touchscreen, powered by an Allen-Bradley PLC. The graphical user interface with a VNC server allows remote two-way communication on any PC, tablet or mobile device. The system offers Ethernet connectivity and can be networked to PCs anywhere.

Schenck Process is unveiling a newly designed Plug Single Tunnel (PST30) diverter valve at NPE2018. The valve’s new features include internally shim-able positive stops, inflatable pneumatic seals at each port, position indication from the tunnel itself, and external tunnel position indication. Additional features include 145° port-to-port rotation combined with the ability to switch between dilute- or dense-phase conveying. The housing, plug and endplates on the aluminum valve are hard anodized for wear resistance. A pneumatic actuator provides a 4-sec actuation time between ports.
