THURSDAY NPE 2018 : THE PLASTICS SHOW SHOW DAILY More sophisticated robot programming is shaving every possible fraction of a second off of cycle time by executing multi-axis move- ments simultaneously, anticipating the move- ments of the clamp and ejectors, and estab- lishing optimum standby positions. Smarter robot controls can learn and adjust timing and positions for such automatic cycle optimi- zation. On the other side of the coin, some controls actually slow down the robot when the cycle permits, saving wear and tear by ensuring the robot doesn't move any faster Robots, continued from page 1 than necessary to get where it is going on time. The speed, precision, and programmability of servomotors have largely replaced pneu- matics on takeout robots—both on the main axes and on wrist rotation. Displayed on the show floor, servo sprue pickers are also having their day while becoming, in fact, mini robots. One supplier notes that servo pickers offer benefits for controlling orientation of demold- ed parts. However, there's general agreement among robot vendors that pneumatics will have a place in simple pick-and-drop applica- tions for some time to come. The constant pressure to squeeze out high- er productivity also means less patience with "flutter" of the robot's vertical axis due to acceleration, deceleration, and machine shock and vibration. Robot suppliers have worked steadily to reduce mass and increase stiffness of robot arms to minimize inherent vibration tendency. They also use software for active vibration suppression—controlling acceleration/deceleration and using small robot counter-motions to dampen vibration (analogous to noise-canceling headphones). Ease of programming has been a steady trend. Some vendors have approached this, in part, by ensuring a consistent interface among all models in their line; another strate- gy has been to apply a similar look and ap- proach to programming six-axis, jointed-arm robots and linear or Cartesian models. And the newest category of robotics—collaborative robots, or "cobots," eliminate the need for spe- cialized programming expertise by employing "lead-through" teach programming, which al- lows the robot to "learn" even complex tasks quickly. Some cobots at the show are equipped with a built-in camera that can scan a QR code at a processing station, which instantly calls up a previously learned program for use at that station.

These harmful condi- tions can be diagnosed without a technical expert using the MachineSense (Booth W3729) Power Analyzer, available on the Siemens Mindsphere IoT platform." "The MachineSense Power Analyzer prod- uct line is uniquely capable because of its Edge Analytic Engine," notes Dr. Biplab Pal, MachineSense co-founder and CTO. "Ex- tremely high velocity current and voltage data are analyzed for anomalies and machine health signature 24/7 using Edge. Power An- alyzer has the most comprehensive range of power quality measurements for diagnosis of electrical lines. Coupled with a cloud data- base and Edge computation, MachineSense's Power Analyzer provides an extensive range of useful analytics for machines in addition to power quality—such as energy utilization, utilization under load, preventative and pre- dictive maintenance advice, and more. No other system can offer such a comprehensive range of Industrial 4.0 analytics in a single sensor suite." Both companies are leveraging the IIoT partnership to offer the marketplace a reli- able and expansive predictive and prescrip- tive maintenance solution while maintaining leadership positions in IIoT and industrial manufacturing arenas. LOVING THE SHOW? MARK YOUR CALENDAR FOR THE NEXT ONE! NPE2021 is scheduled for May 17-21, 2021, at the Orange County Convention Center right here in Orlando, Florida. 2021 NPE2018 New Technology Focus What's New in Resin Conveying With material lines running throughout Conair's booth (W1845), the company's Wave conveying system will be a major feature of its NPE2018 display. By Tony Deligio Plastics Technology Options for moving materials to blenders and processing equipment are getting smarter at NPE2018. Motan's (Booth W1810) Metro- Connect 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 ca- pability added. Motan says that coded cou- pling stations not only prevent coupling er- rors, but in certain fields, they are necessary if material tracking, validation or certification is required. The coupling system is controlled, moni- tored and configured with the MetroConnect controls. Up to eight blower lines can be set up with a maximum of 96 loaders and materi- al 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 al- lows the number of pumps and receiver sta- tions to be customized to fit processors' evolving needs. AEC's VacTrac Plus can con- trol vacuum receivers, vacuum pumps, remote proportioning valves, purge valves, knife gates, and pump or hopper blowback in any resin conveying application across any pro- cess. The control is fully configurable from one to 12 pumps and one to 44 stations. The VacTrac Plus has a 7-in. color touch- screen, powered by an Allen-Bradley PLC. The graphical user interface with a VNC serv- er allows remote two-way communication on any PC, tablet or mobile device. The system offers Ethernet connectivity and can be net- worked to PCs anywhere. Schenck Process (Booth W2683) is unveil- ing 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 abili- ty 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 pro- vides a 4-sec actuation time between ports.
