Material Handling: New Loaders and Receivers Handle Smaller Throughputs for Medical Jobs

Cleanroom-ready design and construction make them well suited for medical processing applications on injection molding machines up to 400 tons.

New MedLine ML Series loaders and MR Series receivers from Conair are specifically designed for bolt-on mounting to Conair MicroWheel dryers or other smaller material hoppers without the need for drilling. They feature electropolished 304 stainless steel construction and are built around a 4.5-inch tubular body for smooth, uninterrupted material flow into attached hoppers.

The ML Series self-contained vacuum loaders are equipped with a 3/8-hp vacuum motor and body seals that enable them to convey materials over distances up to 20 ft (6.1 m). The smaller ML-1 loader has throughputs of up to 75 lb/hr, while the larger ML-2 loader, with a 5-inch-tall glass extension, ranges up to 100 lb/hr.

A quick-disconnect lock and hinged motor assembly offer easy access to the loader body and filter assembly during maintenance or material changes. The optional blowback feature on ML Series motors provides an adjustable cleaning cycle to prolong filter life. A fill sensor in the receiver body communicates with the receiver control to control hopper filling.

The loaders can be run via a range of controls, including the standard ELC-16 control package, which offers user-adjustable loading cycles to match distance and material requirements. The optional ControlMate remote-control pendant, gives users access to a menu of advanced loading controls, as well as the option to add and operate a ratio valve that allows the receiver to simultaneously load virgin and regrind materials. ML-1 loaders can also be operated remotely using the larger, plant-wide conveyor control system: the FLX-128 Plus.

The MR Series Receivers are designed to operate as part of a central vacuum-conveying system, with material delivered through a top-mounted vacuum sequencing valve that can swivel in any direction to simplify hose installation. A quick-disconnect clip opens the hinged lid, swinging the vacuum valve out of the way for easy access to the receiver body and filter screen for maintenance. The MR-1 receiver has a material-holding capacity of 1 lb, while the larger MR-2 receiver has a 5-inch-tall glass extension that increases its capacity to 2 lb. A discharge valve, mounted on the bottom of the receiver, incorporates a demand switch that automatically replenishes the receiver and hopper.

In most cases, MR Series receivers are operated remotely from a central conveying control like the FLX-128, working with a Conair Universal Terminal Box that is mounted on each receiver.  However, MR Series receivers can be operated in standalone mode if they are equipped with a Conair ELS-16 control.
