1. Completing the ASR Part One: The RMX Series Refeed Machine

   July 8, 2015 10:08 am Leave a Comment

   The recovery of scrap generated during the production of blown film, cast film, tape and extrusion coating processes is a key element in reducing manufacturing costs. The Automatic Scrap Recycling system – or ASR®, for short – can recycle trim scrap and off-spec roll scrap in-line and turn your scrap back into profit without the expense of repelletizing.

   A complete ASR system consists of several components, and for the next three weeks Process Control is pleased to detail this patented Automatic Scrap Recycling system. The three components covered will include the following: The RMX Series Refeed Machine, the IN Series Trim Removal Inducer, and the GF Series Film Scrap Grinder.

   Today PCC is happy to show off its RMX Series Refeed Machine. This machine is specifically designed for use with Gravitrol® Gravimetric Extrusion Control Systems. The compact size also makes the RMX Series suitable for applications with headroom restrictions without sacrificing the performance that has made the ASR® Refeed Machine popular for film applications. The unique, double-compartment RMX Series Refeed Machine operates with a variable-speed auger/bridge-breaker assembly to compact and meter ground scrap from the inner hopper to the throat of the production extruder. The outer compartment contains virgin material which is gravity-fed to the throat. The virgin material completely surrounds the ground scrap as it enters the extruder. The extruder screw receives a consistent column of compacted ground scrap surrounded by virgin material.

   This method provides consistent operation without extruder surging or starvation. With the standard extruder follower circuit, the refeed machine will increase or decrease the scrap rate in proportion to the extruder speed. This holds scrap percentage constant without additional operator attention. The touch screen operator panel with smart HMI provides full control and configuration of the drive system with minimal setup. The roll feeder and refeed status may be monitored from a single screen.

2. Product Spotlight: New RMX Series Refeed Machine Operator Panel

   May 13, 2015 12:21 pm 1 Comment

   Process Control is pleased to present an all new RMX Series Refeed Machine Operator Panel available for ASR® Automatic Scrap Recycling. Hardware includes an HMI/PLC combo with Digital and Analog I/O, Modbus, & Ethernet. A variety of AC drive brands are available. The RMX Operator Panel can operate as a standalone system, or it can integrate with PCC (and most other) grinder and roll feed systems. It also comes with the ability to integrate with supervisory systems via Ethernet.
   

   Operation modes for this panel include an auto, manual, and maintenance mode. Auto allows the user to set the speed ratio, and the PLC calculates the correct refeed speed based on extruder speed. Manual allows for direct speed entry, and maintenance provides forward and reverse job for cleanout and inspection. Advanced setup options for this panel include an ad adjustable rate/frequency curve for special materials and a simplified interface. This means you can hide the options you don’t need!

   

   Most importantly, the RMX Series Refeed Machine Operator Panel provides a number of advantages. Smart HMI provides full control and configuration of drive system while competitors require in-panel adjustments. Monitor roll feeder and refeed status are read from a single screen, making the system easier and faster to read, plus system alarms are provided through a pop-up alert so it’s easy to find. Plus there is minimal drive setup because most of the parameters are set onscreen, and an easy switchover to various drive brands.
