A New Look
The machine building industry has changed radically since Design Engineering magazine printed its first issue 1955. The technology has transformed from the purely mechanical to the mechatronic to the digital-mechanical systems the industry is on the threshold of.
Similarly, design tools used to mean a slide rule, a ruler and a mechanical pencil. Today, mechanical engineering has become as much about writing software code and napkin sketches have given way to sophisticated CAD and simulation applications, not to mention 3D printing and scanning technologies.
To stay current with these transformations, Design Engineering regularly overhauls its look to better reflect changes in the market. In this unprecedented year, which marks the magazine’s 65th anniversary, we’ve once again updated our brand, both online and in print.
As you’ll see in this issue, the magazine sports a new logo and layout, as well as a cleaner, more contemporary style with extra white space. The intent is to allow us to explore more creative, eye-catching layouts. Online, the new website design is less cluttered, exposes more of the content and implements some technical bells and whistles that we’ll build upon in the months ahead.
Beyond the aesthetics, the magazine’s content, in print and online, also continues to evolve. The magazine will still offer profiles and features about Canadian engineers and businesses with unique, disruptive and innovative applications. And we’ll keep the top notch editorial from contributors who specialize in the subjects engineers care about.
To that, we look to add deeper dives into the industrial trends and technologies entering the market and shaping the industry’s future. In addition, we hope to meld in a broader range of columnists to better reflect Canada’s shifting engineering landscape.
As the new editor, I enjoyed helping shape the new logo, layout and content as much 15 years ago as today. Then as now, print isn’t enough; readers demand more. And in the same way we ventured early into online content, social media and trade shows in the past, we also look forward to expanding into fresh editorial terrain in the future.
We hope you, our audience, like the new direction we’ve taken as we navigate the next evolutionary step in the magazine’s history. If you have any suggestions or requests for future topic coverage, please don’t hesitate to let us know.

CANADIAN ARMOURED COMBAT SUPPORT VEHICLE BEGINS PRODUCTION
General Dynamics Land Systems-Canada announced it has begun producing the Armoured Combat Support Vehicle (ACSV) in its London, Ontario manufacturing facility.
The ACSV is destined to replace the current M113 Tracked Light Armoured Vehicle (TLAV) and the LAV II Bison and fulfill various combat support roles. The vehicle will be available in eight variants, performing various services, including ambulances, vehicle recovery, engineering, mobile repair, electronic warfare, troop carrying and command posts.
“These vehicles will form the backbone of the Army’s combat support fleet and be used on a wide range of operations including domestic disaster relief and inter national peace support missions,” said Minister of National Defence, Harjit S. Sajjan.
“Thanks to the flexibility found in our defence policy, Strong, Secure, Engaged, work on the vehicles has started years earlier than expected and ensures that we continue to support well-paying Canadian jobs and cr itical innovation in communities across the country.”
Awarded in September 2019, the project contract carries a value of approximately $2 billion for 360 ACSV, initial spare par ts, technical manuals and training. Subcontracts from General Dynamics to companies in seven provinces totaled more than $137 million.
The first ACSV is expected to roll off the production line this December, with deliveries occurring through February 2025. Testing, training and procurement of spare parts will be required before the initial vehicles are distributed to Canadian Ar med Forces bases in 2022. www.gdlscanada.com
PORSCHE 3D PRINTS PISTONS FOR FLAGSHIP 911 MODEL
Porsche announced it has begun 3D printing the pistons for the high-performance engine of its GT2 RS 911 model. According to the sports car maker, additive manufacturing produces pistons that are not only ten percent lighter than the forged pistons but also allows their structure to be optimized to handle the loads acting on them.
The pistons of the 911 GT2 RS were manufactured from highpurity metal powder using the laser metal fusion process.
“Thanks to the new, lighter pistons, we can increase the engine speed, lower the temperature load on the pistons a nd optimize combustion,” explains Frank Ickinger from the advance drive development department at Porsche. “This makes it possible to get up to 30 PS more power from the 700 PS biturbo engine, while at the same time improving efficiency.”
(PS, short for Pferdestrke, is a European power output rating roughly equivalent to bhp.)
The pistons of the 911 GT2 RS were manufactured from high-purity metal powder using the laser metal fusion process (LMF), in which a laser beam heats and melts the powder surface corresponding to the part contour. Porsche initiated the joint project together with partners Mahle and Trumpf; quality validation and component performance were tested using measurement technology from Zeiss.
Porsche already uses additive manufacturing processes in several areas including a 3D-printed bodyform full bucket seat, available since May in its 911 and 718 series. In these models, the seat cushion and backrest surfaces are partly produced by 3D printing. Porsche Classic

MINI-FACTORY CRANKS OUT 50 FACEMASKS PER MINUTE WITHIN A SHIPPING CONTAINER
Swiss OEM, Mikron, announced the development of a mobile automated production line that can produce 50 facemasks per minute (roughly 2 million per month) but fits inside a standard 20ft. shipping container.
According to the company, 45 of its mini-factory containers would be capable of producing enough masks to supply the present needs of Italy.
Mikron’s automation system is the culmination of Project CAROLA, a non-profit initiative to address the global facemask shortage. Using the project’s open source design, engineers worldwide can construct as many of these containerized mask-making systems as needed and place them in remote areas or near locations with the highest demand.
The open source nature of the project also allows for the base system design to be adapted to suit specific installations or needs; any modifications can then be made available to other designers.
According to the project, the design is published under the CERN Open Hardware License 2.0, updated in March 2020 to broaden the legal framework to include

application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs) as well as a wider range of open hardware applications.
For its Project CAROLA system, Mikron turned to project partner Festo for the development of the production line itself.The German automation company contributed engineering, as well as many of the electric and pneumatic components needed to clamp, unwind, shape and fold for the meltblown non-woven fabric the masks are made from.
The line also inserts the metal nose clip and attaches the ear loops. Controlled by a Beckhoff PLC, the system can operate autonomously for more than two hours, given adequate raw materials, the company says.
In addition to the production line inside, Mikron’s containerized system integrates air-conditioning with air purification filters to reduce the risk of viral contamination.
It can make individual masks or shrink-wrapped packs of ten thanks to an automated station developed by fellow Project CAROLA partner, pi4–robotics GmbH.
Project CAROLA partner organizations include CADUS e.V.; Open Source Ecology Ger many e.V. and r0g, the agency for open culture and critical transformation, as well as corporate supporters Mikron, Festo, pi4–robotics and Wikif actory. www.projectcarola.org
Using Project CAROLA’s open source design, engineers worldwide can construct these containerized mask-making systems to satisfy local PPE demand.

The Soft Option
Siemens emphasizes flexibility in software implementation, procurement and functionality with launch of Solid Edge 2021.
BY RALPH GRABOWSKI
Siemens holds a unique position among MCAD software firms: It’s the only one that also operates as a manufacturer. Other big MCAD vendors, like Autodesk and PTC, have presentation centers in which they demonstrate manufacturing on a tiny scale, but Siemens is a manufacturing behemoth that last year made CAD$115 billion – 20x more than its largest CAD software competitor, Dassault Systemes.
Siemens’ CAD division (now called Siemens Digital Industries Software) is also the largest CAD vendor to resist today’s notion that design software must run on the cloud, a position that is in direct contrast to competitors, who find customers still clinging to desktops irritating. For Siemens Digital Industries Software CEO Tony Hemmelgar n, design belongs on the desktop, end of story.
“We will never have to have that hard discussion with customers about them having to make a difficult transition of technologies [from desktop to cloud],” he said.
What does belong in the cloud is collaboration, he says, and so Siemens is working at making its popular Teamcenter collaborative software run on the cloud, under the name Teamcenter X. You can see how this makes sense: Engineers have powerful desktop systems running NX or Solid Edge, but collaborate with each other and fieldworkers through the cloud.
And even when it does come to the

cloud, Siemens offers unusual flexibility. You can choose to have the software hosted by Siemens (on Amazon), by pr ivate or local cloud providers, on premises, at the edge or hybrids thereof. No one else offers this.
You Pay Your Way
Siemens also insists that customers have a choice in how they pay for software, whether through permanent licenses or by subscription. Hemmelgarn says he is surprised by how many of his competitors have forced customers onto subscriptions.
Despite his declaration, the company is nevertheless pushing forward with software that can only be paid for by subscription. It turns out that CAD vendors who go to the cloud have no

choice in the matter; software that runs non-stop on the cloud has to be paid for non-stop to cloud providers like Amazon, and so customers also have to pay non-stop.
If we understand nothing else about Siemens’ future, it’s that it will be based on Mendix. This platform with the odd name has an equally odd history: It began as a cloud-based visual prog ramming service for business applications, like human resources and scheduling. Two years ago, Siemens bought it for CAD$950 million and then applied it to CAD.
We can think of Mendix as a combination of Autodesk’s Forge API and PTC’s Onshape/Atlas platform. The no/low code app development platform has a three-fold role at Siemens: As a set of software for running businesses; an API for customers to customize; and as the underlaying technology that powers all cloudbased apps for Siemens.
“We are launching a lot of applications based on Mendix,” said senior VP of business strategy and marketing, Brenda Discher, formerly of Autodesk marketing.
What’s New in Solid Edge 2021
In July 2020, Siemens held a dedicated launch event for Solid Edge 2021, at which it emphasized the doit-all nature of its mid-range software. Presenter Dan Staples, VP of R&D, boasted that Solid Edge has “the best mechanical design in the marketplace.”
In addition to MCAD, the company also pushed that Solid Edge 2021 now encompasses a number of related design functions, including electrical design, simulation, data management and collaboration. In reality, the implementation of those functions in Solid Edge isn’t quite as complete as the marketing might suggest. While Siemens, as a whole, does possess a wide breadth of software offerings, Solid Edge 2021 depends on external applications to perform those functions
Electrical design in Solid Edge, for example, consists primarily of designing cabinets and auto-routing wire harnesses; it doesn’t actually do

electrical design but instead depends on importing electrical and PCB designs through TeamCenter.
Similarly, data management in Solid Edge requires parts of TeamCenter to control drawings and other files, while cloud-based collaboration depends

What’s New in Solid Edge 2021
Within stand-alone Solid Edge 2021, Siemens touted Subdivision modeling as the number-one feature. This modeling method is meant for industrial designers who make organic-looking things like the swoopy shell of a mouse or camera body. The emphasis in sub-D is looks not accuracy.
In this form of modeling, you begin with a primitive, like a box or sphere, and then interactively push and pull mesh areas to get closer and closer to the shape you want. When you need greater detail, you sub-divide sections of the mesh into denser, higher resolution areas. Sharp corners are added by manipulating edges. Solid Edge also includes a handy mirror function, so that anything you do on one half of a model is replicated in the other half to create a perfectly symmetrical result. Arriving at a curvy mouse or camera body is faster with sub-D modeling than with solid modeling, but eventually the mesh needs to work with solids. Here, Siemens offers Convergent Modeling, that is the ability to combine disparate geometr y data in a single model, including parametric and sub-D geometry as well as generative and reverse-engineered (3D
scans). Sub-D modeling is included with both the Classic and Premium versions of Solid Edge 2021, so you don’t pay extra for it.
Here’s a run down of other new features:
Modeling: To make large assemblies faster, all parts are kept in a single assembly file. Internal relationships (like constraints) are remembered when copying and pasting parts from one assembly to another. Frames can have gaps to allow for welds, and semi-automatically add inward or outward end-caps with optional offsets and chamfers. Nesting now optimizes part placement on unusual shapes.
Sheetmetal: Multiple edges receive flanges by selecting and pulling them, and partial flanges can be constructed. The decals command places images and logos, even across multiple faces.
Simulation: The 2021 release adds electronics air cooling analysis from Simcenter’s FloEFD fluid simulation module. Package Creator defines the packaging and solder points of chips. Modern chips generate a lot of heat, so simulation in Solid Edge now handles the impact of air flow from cooling of fans, shown as temperature curves and iso-surfaces that represent air flow direction, velocity and temperature. Structural designs also can take temperature into account.
User Interface: The new Adaptive UI tracks commands you are working with, and then guesses at the next command you might need. CAD managers can take output from experienced

Solid Edge 2021 integrates with Simcenter’s FloEFD fluid simulation module for thermal analysis such as airflow from cooling fans.
Siemens also insists that customers have a choice in how they pay for software, whether through permanent licenses or by subscription.
users and give it to novice users as they learn to do specific tasks, with Solid Edge telling them the next command to employ.
Parts Catalog: Siemens licensed the Cadenas parts library to provide Solid Edge 2021 with 1,500 manufacturers’ catalogs. There is a visual search function that returns results sorted by percentage likelihood of matching your request.
This is an era where, it seems to me, some CAD vendors concentrate harder on collecting subscr iptions from customers than improving their software.
So it is good to see Siemens going all out by loading up this year’s release of Solid Edge with lots of new functions.
During the launch event, the host introduced Solid Edge 2021 by saying, “We bring the technologies of tomorrow to our customers today.” But some new features, like sub-D modeling and electrical design, were long needed to catch up with competitors AutoCAD and Solidworks, respectively. The improvements to fluid simulation were, I suspect, in reaction to Discovery Live
fluid simulation added by PTC to Creo last year. Other new features, like the “AI”-enabled interface, are trickle-downs from earlier releases of NX.
Nevermind. Siemens places the emphases in the right areas. Design belongs on the desktop; subscriptions ought to be optional; automatic upgrades pausable and collaboration should be hostable anywhere. These are policies that reassure customers that their future with Siemens is a stable one.
Solid Edge 2021 is expected to ship in August. It is free to students (including self-learners) and star tups (in business under three years, under $1 million in revenues). For everyone else, the 30-day free trial can be downloaded (after registration) from the Siemens PLM website. |DE https://solidedge.siemens. com

Changing the Game
Mountain bike makers turn to engineered plastics to cut weight and resist corrosion.
BY THOMAS RENNER
There is a lot to explore in Canada and more and more people are discovering that the best way to see Canada’s splendid scenery is with mountain bikes. In total, there are 27,669 trails covering 27,145 miles in Canada, where industry statistics claim nearly 1.3 million people participate in the sport. A favorite among North American mountain biking cyclists, Whistler Mountain alone includes 70 bike trails covering 80 kilometers.
In the past decade, there has been a substantial shift in components used in mountain bikes. Many
mountain bike manufacturers are now turning to highly technical, cost-saving eng ineered plastic components that weigh less, resist contamination and stand up to the rigorous demands of mountain biking.
“We see the benefits of igus parts, especially since the bikes are put through some harsh conditions and contamination where metal parts break down faster and can cause failures, where plastics generally don’t,’’ said Megan Tompkins, the global marketing director at Crankbrothers, which has been using igus materials in its pedals since 2015. “I can see more and more manufacturers switching
two years also include igus bushings in the lower link. The bushings are in the bike’s clevis, a U-shaped connector fastened by a bolt or pin passing through the ends of the connector.
“We had always used sealed cartridge ball bearings in all of our pivots,’’ said Colin Hughes, lead engineer for ibis. “It was what the customer always wanted, but some of our highest load pivots moved less than 20 degrees. It did not seem to matter how high the quality of a ball bearing I specified. It would always start feeling notchy prematurely.”
Similarly, Crankbrothers manufactures a range of components for mountain bikes, including wheels, handlebars, pumps, pedals, and dropper posts, which allow riders to adjust the seat to adapt to variable terrain. Bushings from igus are included in several models of pedals, and they are also included in the company’s Highline dropper seat post.
to plastic components now that the industry is seeing the benefits.”
Where They are Found
Mountain bike manufacturers find similar advantages in igus products, but they are applied differently throughout the bike. For example, mountain bike manufacturer, ibis Cycles, uses igus bushing in its full suspension frames.
Founded in 1981, the company has been using igus components since 2013. Plastic bushings were first included in the Ripley, the company’s original model. Four new models of ibis mountain bikes introduced over the past
“All five Highline dropper seat posts (ranging from 80 to 170 millimeters) use igus bushings and keys,’’ Tompkins said. “Nearly all of Crankbrothers p edals use igus bearings. The clipless pedals use a custom sleeve bearing and the stamps use a custom double bushing-bearing system. All the igus parts Crankbrothers uses are for the specific design.”
Corrosion Resistant, Enhanced Durability
igus products are included in a wide range of industries: Robotics, cranes, m edical equipment, food processing, and material handling, to name a few. The advantages of igus materials also make them ideal (Photo

In the near future, nearly all mountain bikes are likely to

for mountain bikes. The dry-running, lightweight and durability properties in engineered plastics make them suitable for almost any field.
“After the first year when the new frames that featured igus were on the market, I started receiving feedback from consumers who had taken their frames apart for maintenance,’’ Hughes said. “I got a few from the United Kingdom where the owners were shocked by how well they are holding up.”
Before switching, Crankbrothers had been using needle bearings or Delrin bushings (a thermoplastic designed to replace metal) and brass keys in its products. “We experienced some corrosion,’’ said Tompkins. “We were also trying to solve issues with durability and precision fits.”
The company completed ride testing and accelerated lab testing to see how the components would handle the demands on a mountain bike. “The igus components performed better than current polymer bearings, and there was no corrosion,’’ Tompkins said. “From our research, the results were what we had expected, but we were still quite pleased.”
Matt Floyd, igus’ West region sales manager, started introducing engineered plastics to mountain biking companies in 2012 and has seen significant growth.
“The contamination and wear with metal made it challenging for the mountain biking industry,’’ Floyd said. “It also created unnecessary weight and accelerated wear and friction. We were able to reduce costs without affecting performance and feel.”
Silencing Skeptics
Robin Wallner, who joined the ibis racing team in 2014, ranked 11th in the world in the Enduro World Series last year. In 2018, he had his best year, recording three Top 10 finishes in the Enduro World Series and at one point
rose to second in the world before a broken hand ended his season.
As a veteran rider, Wallner is
particularly attuned to his bike. When ibis said it was interested in using igus components, he was skeptical.
“I had some concerns that plastic wasn’t going to hold up against the forces that we put on our bikes,’’ Wallner said. “I wasn’t sure how it would withstand the abuse of dirt, water and other bike path debris.”
But since switching to the igus

plastics have helped his bike become lighter, stiffer and more cost effective. While he is world-ranked, the same properties also appeal to the millions of recreational cyclists who also zip down rugged mountain terrain.
“All mountain biking technology is developed with racing, but the majority of the technology is used by recreation cyclists,’’ Floyd said. “Everything is developed with speed in mind.”
Challenging Terrain
Mountain bikers ride on terrain that includes roots, rocks, mud, grass, sticks, gullies and jumps. Bikes take a substantial pounding, and durability is put to the test every time down the mountain. A mechanical breakdown in any component could result in an injur ious spill. The average mountain bike speed on single track is approximately 10
miles per hour, but can reach speeds up to 55 MPH on downhill trails.
Rider s want their bikes to absorb the frequent bumpy paths without mechanical breakdowns, but they also demand comfor t, precise feel and light weight. Mountain bikes with metal components weigh an average of 30 pounds. Shaving weight with plastic components puts less stress on the frame and can make the bike easier to maneuver.
In the near future, nearly all mountain bikes are likely to include some high-performance plastics. Performance, durability, lightweight and less maintenance are features that resonate with every rider, whether they are competing against the globe’s best or cruising on a weekend trek. |DE www.igus.com

NEXT GEN CONVEYORS
Evolution of linear motor transport systems opens near limitless conveyance possibilities.
Since ATS Automation released its first SuperTrak system in 2001, linear track conveyance systems (also known as smar t conveyors or linear motor transfer systems) have become an increasingly popular upgrade from conventional belt or chain driven conveyor systems.
In the early days, ATS and MagneMotion (now part of Rockwell Automation) where the only game in town but have been joined by Beckhoff, Festo and Bosch Rexroth, as well as a few smaller players. In addition, the product segment has continued to mature in that suppliers have differentiated their systems to stand out from the crowd.
Whoever makes the system, they all operate based more or less on the same principle. At the core is a track composed of straight and/or curved linear motor segments. Joining them together allows for the conveyor’s path to be configured in various geometries to suit different applications. Unlike most traditional conveyors, smart track systems don’t need to be horizontal but can be oriented vertically or tipped on end.
Along the edge of the track run the shuttles (aka movers, pallets or carriers depending on manufacturer). These movers are affixed to the track primarily by wheels but aided by the attraction between the linear motors’ electromagnetic coils and permanent magnets in the shuttle. By manipulating the activation of the coils, each shuttle can be programmed to move around the track, individually or in groups, at different speeds, accelerations and/or directions, as needed.
In part, it’s that independent motion that makes linear motor transport systems a powerful solution. Asynchronous motion allows shortening cycle times since parts don’t all progress through the manufacturing process at the same set pace. Adding in the high speeds and acceleration/deceleration possible means par ts spend less time moving between work stations.
A related but less obvious strength of these systems is their micron level precision, enabled by a linear encoder scale on the track. Consequently, the conveyance system can participate in the manufacturing process itself. For example, the x-axis motion of the shuttle can be coordinated with motion at a process station to simplify tooling operations. These systems also possess built-in collision avoidance, auto-queuing and auto indexing capabilities.
Beyond speed and independent motion, linear motor conveyance systems are also highly
As the original “smart” conveyor, the ATS SuperTrak Gen3 has matured considerably since its introduction 20 years ago.
flexible; tracks can be scaled by adding or removing track and shuttles or reconfigured to new geometries. In addition, reprogramming happens quickly by swapping motion profiles in software, thereby enabling multiple product lines and shortened change over. These systems also consume less electricity and require less maintenance than conventional conveyors since the wheels are the only moving parts.
One of the often overlooked advantages linear motor transfer systems afford, says Ben Hope, product manager for SuperTrak CONVEYANCE at ATS Automation, is the ability to condense an operation’s footprint.
“Footprint size effects revenue per square foot, especially in areas where real estate is expensive,” he says. “Compared to transitional synchronous conveyance, independent asynchronous shuttle control provides the means to change shuttle pitch allowing the system to use only the space required.”
ATS SuperTrak
Now in its third generation, the performance of ATS’ SuperTrak has improved substantially since it’s first iteration. For example, shuttles on the current SuperTrak Gen3 can handle payloads up to 10kg (up from 1kg in the first generation) while the maximum speed each shuttle now reaches is 4m/s unloaded, (up from 1m/s).
Similarly, each shuttle’s maximum acceleration is now 39.2m/s2 (4g) with a 1-kilogram payload. With a 10kg load, acceleration tops out at 1g. In addition, the SuperTrak Gen3 features fully controllable corner segments, rather than the rotating drums on the company’s previous iterations.
F rom a control engineering perspective, each shuttle functions as a separate servo axis. To program them, ATS provides its TrakMaster software in which engineers can digitally model a track design and simulate the overall conveyance sequence by fine tuning shuttle motion, acceleration, stop locations and shuttle coordination. Once the bugs are worked out virtually, the motion profiles can be output to integrate with Ethernet/ IP, ProfiNet or other protocol-based systems.
Beyond improvements to SuperTrak, ATS released a related linear motor conveyor line last year, called SuperTrack Micro, that expands the concept to encompass sorting and diverting operations. By positioning two oval tracks in close proximity, the Micro’s “double-sided shuttles” can switch between tracks at full speed. This allows for one or more shuttles to be diverted for additional operations or part inspection, and then merged back onto the originating track, when and if needed.
For that added functionality, the trade-off is a reduction in per shuttle payload capacity (1.5kg for a 50mm-wide shuttle and 3kg for a 100mm shuttle).
Beckhoff’s eXtended Transport System (XTS) offers the widest range of track geometries, including straight, oval, circle, square, rectangular and S-shaped.
In addition, top speed is limited to 3m/s and acceleration is reduced to 1.5g with a 1.5kg payload (or 5g with a 0.25kg payload).
Beckhoff XTS
While the same in concept, Beckhoff Automation’s eXtended Transport System (XTS) differ s from other systems in terms of its mechanics and design flexibility. For example, the system’s six or 12 wheeled shuttles (or movers) are fully captive, “gripping” the horizontally oriented linear motor track like a C-clamp and the movers’ magnets engage the motor coil both above and below the track to balance the magnetic force.
Practically speaking, XTS track length tops out at 100M with approximately 200 movers, depending on computation limits. Unloaded, XTS movers can accelerate up to 100m/s 2 (10g) reaching a top speed of 4m/s. With its maximum ~8kg payload, standard mover acceleration drops to 2m/s2 (.2g).
Mover positioning accuracy is less than ±0.15mm at 1.5m/s with repeatability of less than ±.01mm. As with other linear motor systems, movers can also apply force between them to act as make-shift grippers. At standstill, XTS movers can apply up to 100N or a continuous force of 30N while in motion.
Beyond its specs, what makes the XTS stand out is that Beckhoff has fully explored the potential of the linear motor conveyance concept. Most notably, XTS allows for multiple track geometries. In addition
to straight 250mm segments and 180 degree corners, the company also offers 90 and inside/outside 22.5 degree turns. Combining them opens the possibility of not only straight and oval tracks, but also circle, square, rectangular, S-shaped tracks and any permutation thereof.
“From a mechanical standpoint, the compact size of our system is often key,” says Calvin Wallace, managing director, Beckhoff Canada. “It’s not only the small track, but also the simplicity of the control system; all that’s required is an IPC, TwinCAT automation software and EtherCAT.”
Like ATS’ SuperTrak Micro, Beckhoff has also expanded XTS into multiple track configurations by taking the concept into the third dimension; two or more tracks can be stacked on top of each other to enable sorting, diverting and merging shuttles but without taking up additional floor space. In effect, this is facilitated by “elevators,” specialized sections of straight track that can raise or lower shuttles from one track level to another.
XTS also comes in specialized versions. The XTS Black line, for example, offers motor modules that support integration of third-party track systems for higher-payload applications. The company’s XTS Hygienic line carries an IP 69K rating due to its stainless steel surfaces, with no hidden edges or undercuts, and sealed joints. Designed for the pharma and food industries, the line is suitable for applications that require high-pressure washdown.
Festo Multi-Carrier-System
More so than other smart conveyors, the Festo/Siemens Multi-Carrier-System (MCS) excels at integrating with an existing production line. While there is a self-contained track option, MCS is often
implemented only where asynchronous movement is needed.
As a result, MCS is one of the most customizable of linear motor systems. Since it can mesh with most traditional conveyors, Festo engineers transitions between MCS motor segments and belt, chain, etc dr iven conveyors. Carriers, as well, come in multiple sizes and types to suit the application and facilitate the hand-off between sections.
“Because we can customize these systems, there isn’t really a payload limit,” says David Dolezal, electric automation business development manager with Festo Canada. “We’ve designed MCS systems to handle everything from a few grams to 150kg because we can gang motor segments together in parallel to move a heavy load. We can build the system to whatever the application requires.”
For single-width motor implementations, in line with other systems, MCS payload tops out at 4kg. Unloaded, maximum carrier speed is 4m/s with a maximum acceleration 50m/s² (5g) and repetition accuracy of ±.05mm when in the direction of travel.
In its standard form, the MCS offers 102mm and 306mm sections of linear motor track for potentially unlimited track length. However, each track segment requires one or more motor cables connected to a Siemens controller, depending on application complexity, plus an encoder cable for closedloop implementations.
To design a Multi-Carrier-System, Siemens’ MCS Creator softw are enables graphical drag-and-drop layout and configuration of the motor segments . User can also create a bill of materials and select a suitable controller type. Detailed programming is performed with the RailControl software library in which carriers are treated as virtual axes
and motion functions, such as positioning, gear synchronization, curve synchronization or path interpolation, can be used.
Rockwell iTRAK
Finally, Rockwell Automation’s iTRAK system combines the strengths of other linear motor conveyors and sports impressive specs. Available in two variants, iTRAK motors come in straight and 90 degree segments, allowing for straight and racetrak ovals, as well as rectangular and square configurations. Furthermore, each segment contains a motor, drive and encoder.
The workhorse of the pair, the iTRAK Medium Frame, allows for tracks up to 100 meters long (256 sections) with up to 250 movers, each of which can handle payloads up to 40kg. Unloaded, mover top speed is 5m/s with accelerations greater than ~100m/s2 (10g).
Peak force attainable is contingent on motor coil and mover width, ranging from 88N for 50mm motor and mover width up to 793N when 150mm
Highly customizable, the Festo/ Siemens Multi-CarrierSystem is designed to integrate with nearly any traditional conveyor type.
motor segments are paired with 150mm-wide movers. In addition, mover repeatability hovers at ±0.03mm and minimum pitch ranges between 66 to 75mm.
As of May 2020, Rockwell also offers the iTRAK Small Frame, designed for food and beverage and packaging applications, that shares its partner’s flexibility but not its brawn. While mover top speed is also 5m/s, payload per mover tops out at 4kg and peak force is 100N.
In addition, track size is limited to approximately 64 motor sections and 128 movers total. On the upside, the Small Frame features a stainless steel track and carries an IP66 rating. In addition, mover pitch is reduced to 50mm and repeatability is +/- 0.01 mm.
While the iTRAK is in line with other smart conveyors discussed here, the company offers the widest range of linear motor products in terms of application. The MagneMotion Lite, for example offers fast programmable motion and intr icate branching pathways for small payloads (2.5 kg per mover) while Rockwell’s QuickStick 100 and HT lines handle payloads as large as 100kg or into the thousands of kilograms, respectively.
This smart conveyor overview only scratches the surface of these systems’ potential and limitations. And while there are numerous advantages, it should be noted that they carry a higher initial price tag than traditional systems. However, proponents of the technology point out that since they are quicker to design and build, require less maintenance and power consumption a nd increased up-time, comparing total cost of ownership is a nuanced calculation. |DE https://atsautomation.com http://beckhoff.com festo.com rockwellautomation.com
