PaR Systems Uses Siemens Digital Tools to Make Crane Operations More Productive and Safe

It’s happened too many times: injuries, fatalities, and damage to plant assets resulting from crane-related accidents. The complex work performed by material handling cranes within aerospace, automotive, and metal processing facilities can lead to dangerous and costly accidents. How common is the problem? According to the Crane Inspection and Certification Bureau (CICB), approximately 80 crane-related deaths occur every year. Of all crane-related incidents, 90% are due to human error, 50% of the overall incidents result in a fatality, and 40% of the overall incidents involve someone being struck by the crane or an object that the crane is lifting or moving. Most of these errors correlate to a lack of operator training.

The Solution

Fortunately, recent advancements in digital technologies have fueled innovation in the field of crane control, and new solutions have been developed that are safer and smarter. One unique solution for modernizing cranes was designed to help operators by reducing load sway by a stunning 95%. This innovative solution, EXPERTOPERATOR™, was developed by PaR Systems (PaR) of Shoreview, Minnesota (www.par.com). PaR is a global manufacturer of advanced automation, robotic, and specialty material handling solutions. PaR supports global customers in automotive, aerospace, nuclear, life science, marine and other core industries.

EXPERTOPERATOR is an advanced crane motion control system implemented entirely within the Siemens platform. The system uses equipment such as Simatic S7 PLCs, Simatic HMI Panels, and Scalance W Industrial Wireless Modules. Unique algorithms within PaR’s software enables crane operators to more easily, quickly, and safely control the movements of payloads, such as dies and coils in automotive stamping plants. EXPERTOPERATOR is most effective for applications that require high throughput, and precise manipulation of loads to meet production demands and prevent collisions with sensitive equipment and personnel.

EXPERTOPERATOR is currently installed on over 150 cranes worldwide – many of which are located in automotive, primary metal, and heavy equipment industry facilities. Users have indicated that EXPERTOPERATOR has allowed operators to control their crane loads with 95% less sway and 90% fewer “close calls” or collisions. Optional modules to the EXPERTOPERATOR platform provide robust zone control, sideload/snag prevention, and automatic load positioning.

How material handling customers are benefitting from EXPERTOPERATOR

Across 150 installations, EXPERTOPERATOR has improved personnel safety, reduced damages to equipment, increased efficiency, and reduced maintenance costs.

  1. Heightened safety of people and product – EXPERTOPERATOR minimizes payload motion by intercepting an operator’s commands and adjusting the output to emulate those of an experienced operator. This technology is proven to reduce cable sway by 85-95%. Thus, operator concentration can be focused both on the load and on the immediate environment surrounding the adjacent plant floor, instead of controlling load sway. As a result, both the load and the surrounding equipment are less likely to suffer damage.
  2. Increased efficiency and productivity – Many of PaR’s customers run 24×7 operations and have reported significant improvements in productivity. For example, one customer in a high-throughput locomotive manufacturing process reported that the critical path load positioning time was reduced from approximately 4 minutes to less than 2 minutes. This result is not atypical. End users who implement EXPERTOPERATOR generally report between 10 and 50% reduction in load positioning time.
  3. Easier-to-use crane operations – Increased productivity is due – in part – to the reduction of load swing, which makes the crane easier to operate efficiently. The intense manual manipulation ordinarily required by an operator to mitigate load swing is replaced by a simpler manipulation task: positioning a stabilized and swing-free load.

The evidence that EXPERTOPERATOR makes cranes easier to operate is further demonstrated by data captured through operator studies that measured the frequency of button pushes. While using the technology, operators pressed pendant buttons 60- 80% less than while conducting the same manipulation task without EXPERTOPERATOR. This metric demonstrates that fewer commands are needed to manipulate a swing-free load.

  1. Rapid Operator Training – Because EXPERTOPERATOR makes cranes easier to use, novice operators can quickly become proficient. In fact, new operators who utilize the technology generally perform as well or better than their more experienced counterparts who use conventional cranes. This technology effectively accelerates the rate at which operators learn to drive safely and efficiently.
  2. Reduced maintenance costs – Each time a crane operator pushes a button, electric current rushes through the power section of the drives. The current also flows into the motors, and this causes torque to be propagated in the mechanical drive train through to the gears, wheels, and finally the rails of the crane’s infrastructure. When the number of starts, stops and surges in current are reduced by 60-80% with EXPERTOPERATOR, the life of that critical equipment is prolonged. As a result, the mean time between failure (MTBF) statistic is improved by a factor of 2-3 times and maintenance costs are drastically reduced.

 

Siemens reliable products and time-saving tools add value PaR Systems relied on Siemens because they place a priority on reliability and quality.

PaR Systems knew their success would depend on their ability to work with a partner who could provide critical hardware that is robust for industrial environments, quick to deploy, and highly configurable.

In material handling crane operations, wireless capability is a key operational factor. The Siemens Scalance W wireless solution offered PaR Systems a wireless component that was reliable and predictable. PaR had experience with non-Siemens wireless solutions in the past that were problematic, both functionally, and from a manufacturer support perspective. The Scalance W wireless solution can be configured to operate in a less congested frequency range (5 GHz), allowing for a more robust wireless signal. Since installing Siemens Scalance W wireless modules as part of their solutions, customers have experienced 100% uptime of their wireless communications. In addition to reliability, the Scalance Wireless Modules offered PaR exceptional customer and OEM technical support.

EXPERTOPERATOR is an advanced crane motion control system that is implemented entirely within the Siemens platform. The system uses equipment such as Simatic S7 PLCs, Simatic HMI Panels, and Scalance W Industrial Wireless Modules.

Time to market is also important to PaR Systems when delivering customer solutions. The Siemens Totally Integrated Automation (TIA) portal provided a platform to shorten engineering time through its simulation tools, programmer productivity tools, and additional diagnostics. PaR Systems benefitted from unique capabilities when programming the Simatic S7 PLCs and Simatic HMI Panel. They were able to dynamically change the cycle time of the main control loop during runtime, which is critical for optimizing the performance of their unique motion control. Debugging capabilities were enhanced because the tool monitors values and updates programs in real time for instantaneous feedback. Such tasks that are tedious and time consuming within other platforms happen automatically and dynamically when using the Siemens TIA solutions.

Material handling requires a fine balance between precision, efficiency, productivity, and most importantly, safety. As a result of the collaboration between PaR Systems and Siemens, new and experienced crane operators around the world can now confidently perform their tasks and contribute to enhanced plant safety and operational efficiency, while reducing equipment maintenance.

Digitalization…Its Time Has Come!

By Ryan Jarvis, Head of Vertical Markets for Food, Beverage & CPG, Siemens Industry, Inc., Factory Automation

Ryan JarvisEditor Note: In this article, the author makes the case for the digital factory in food & beverage processing.  Much of the input here resulted from a “panel of experts” discussion held recently at the 2018 Manufacturing in America trade event, sponsored by Siemens at Ford Field in downtown Detroit, Michigan. 

In a recent study we conducted at Siemens, where we talked to 40 firms in food & beverage, it was determined that over 50% of firms are already using connected sensors in their operations.  Likewise, 60% are using digitalization tools such as track-and-trace to monitor ingredient flow through their supply chain.  Finally, over two-thirds of those surveyed are encouraging their suppliers to provide data from their own operations and production processes, improving transparency and creating new opportunities to drive efficiencies.

That’s the good news.

On the flip side, less than half are using advanced data analytics, 85% have lag times over 24 hours between data collection and analysis, plus, perhaps the most challenging fact, over a quarter of the companies surveyed do not yet have a fully defined data management strategy.

In the past, the notion of a food or beverage processor being able to look at a prioritized set of data, in the cloud, in real time, making OEE, shift or even complete plant utilization assessments and sending instantaneous triggers for corrective action to the factory floor with remote, ongoing data back-up for further analysis that included supply chain and even consumer feedback would have been a wish list item.

Not anymore.

With the onset of complete product lifecycle management (PLM) technology, coupled with advanced machine controls, data gathering devices and communications software, with platform-as-a-service capabilities, today’s processor can transition to the digital factory with greater ease and confidence than previously thought possible.  As one industry expert observed, “Digitalization is making its entry into our market, but it does require management to have vision, a competent team to do an evaluation and a trusted supply chain of vendors and integrators to make it happen.”

Line efficiency, speed, product validation, production tracking and, a rapidly emerging trend in our business, namely, the need to have flexibility in the line for changeovers to meet the increased variety demands of the buying public are all drivers in this rapidly evolving landscape of the digital factory.

Expanding on some of these points:

  1. The cost of downtime can be hundreds of thousands of dollars a day. By using sensors to monitor machinery, plant personnel can gain access in real-time to all data on performance, quality and associated profitability.  Predictive analysis and maintenance can significantly reduce downtime by anticipating faults and failures before they occur.
  2. Higher productivity with lower inventory can be achieved more easily in a digital environment, as every aspect of production is constantly monitored, while order histories are compared and extended out into the production cycle expectations. One meat product producer saves hundreds of thousands of dollars every year from tracking weight variances, for example, realizing just a 0.10% improvement in yield.
  3. Mobile monitoring, RFID tags and in-package sensors are tracking a variety of real-time information to ensure compliance with cold-chain requirements. The trade associations are likewise moving into a standardized set of communication protocols…think OMAC and PAC ML…to streamline the connectivity and data tracking of processing and production lines alike.

 

During the recent Manufacturing in America event at Ford Field in Detroit, at a Futures Forum sponsored by Siemens, a panel of industry experts from various segments of the food, beverage and CPG market gathered to discuss the trends in digitalization and its impact on their companies, their equipment and, of critical importance, their people, both current and future team members. 

This recap summarizes a very lively 90-minute discussion held at the Forum, which was moderated by the author. 

Panelists for Manufacturing in America Food, Beverage & CPG Futures Forum (left to right in photo) Todd Slater Manager-Design/R&D Supply Chain Center of Excellence Bill Meier Principal Controls Global Technology Engineer Mars Wrigley Confectionery Co. Patrick Zambon Controls Engineer Founders Brewing Co. Ryan Jarvis Head of Vertical Markets for Food, Beverage & CPG Siemens Factory Automation Dave Greenfield Director of Content/Editor-in-Chief Automation World (trade publication) Cameron Cane President Deutsche Beverage Charles I. Sheets, PE Master Engineer – Automation Industrial Systems Division Matrix Technologies Inc.

The session included a review of the best practices and outlook for digitalization among the manufacturers, equipment builders and others in the supply chain, as well as the editor from a leading automation trade magazine.

While the participants were already engaged at different levels in the digitalization process, one remaining hurdle was exactly that degree of difference, as it impacts their relationship with vendors, distributors, automation integrators and end users alike.

Most all at the forum had significant automation and digital factory initiatives in progress or planned for the near future, a very positive sign for the industry in its quest for global competitiveness.

As consumer demand for product diversification, transparency in ingredient sourcing and even the packaging variances between the local grocer and the big box retail operation all affect the operation of the food & beverage industry, the future opportunities for digitalization and its possibilities for manufacturers will continue to expand at a rapid pace.

Another key concern for the group was the process of introducing employees, including those with decades of experience on the job but little exposure to the digital world, to this emerging trend.  Most companies were actively engaged in training, both for the current labor force and the next generation.  It was agreed that the machines and equipment in the factory needed to reflect the HMI qualities of the consumer electronics that occupy so much of modern life today.  As a collateral benefit, the digital factory, by definition, would attract more young talent to enter the manufacturing field.  As one participant put it, “They expect digital nowadays.”

On the logistics of implementing digitalization, it was unanimously agreed that one-off projects would not achieve the desired results with any efficiencies.  The better approach was a thorough plan, developed by the end user working with their machinery, equipment and automation suppliers, as well as customers, to achieve an optimum hierarchy of needs.

All agreed line efficiency and speed were paramount on the scale of basic requirements for an effective system.  Product validation and production tracking in a digital environment means analyzing not merely collecting data, in real time.  The goal is delivery of actionable knowledge about the process, they concurred.

For the factory floor, the impact of robotics was a very lively topic of discussion.  It was noted that “…robots can replace but also augment people and this will require an entirely new paradigm of ergonomics.”

On the financial front, it was agreed that driving management to implement digitalization must be more than a decision about dollars.  The future of the companies that were major players in food & beverage 50 years ago was directly tied to their willingness to adapt every aspect of their companies to the changing tastes and purchasing practices of the buying public.  Today, there are myriad means available for the younger generation to acquire everything they touch, wear, taste, drive and consume.  The smart companies, it was mused, will be the SMART companies, meaning those who incorporate the digital factory precepts into their entire operation and company vision.

The following list was suggested as areas where digitalization would have influence in the industry today…

  • Product development
  • Line design
  • Manufacturing layout
  • Scalability of production
  • Importance of industry and trade association standards
  • Data/Control/Analysis
  • Packaging
  • Adding value and pricing structures
  • Customer influencing/User experience with product
  • Fair treatment of sourcing locations and resident talent base
  • GMO/Good Citizen Status/Defect Detection
  • Product lifecycle and MES

Finally, the fun part…an outlook overview on the future of the market, from the perspective of the participants on the panel and in the audience.  All the following areas were discussed as potential and, in some cases, already initiated areas for digitalization to become a positive factor…

  • Traceability for immediate resolution as a driver of brand equity
  • Higher levels of automation along the entire process chain
  • Competitive trends being accelerated
  • Block chain evolution that will further accelerate the buy cycles
  • Long range scanning by metrology methods for improved plant utilization improvement
  • Ongoing use of digitalization to track machine operations and security of all data
  • Faster time to market through a pro-active effort between users and their machine OEMs and retrofitters alike, to anticipate trends and react
  • Consumer expectation modeling
  • Response paradigm for companies, as they address the needs for internal improvements

Little Patuxent Water Reclamation Facility Upgrades System with AirPrex® for Sludge Optimization and P-Recovery

CNP – Technology Water and Biosolids, a division of Centrisys Corporation in Kenosha, Wisconsin, recently supplied the Howard County Department of Public Works with the patented CNP AirPrex process. AirPrex, scheduled to be operational during the Q3 2018, will improve the current biosolids processing facility by sequestering phosphorous and preventing the formation of phosphorous scale known as struvite.

Howard County Department of Public Works engaged HDR to provide engineering design services for upgrades to the biosolids facilities at the Little Patuxent Water Reclamation Facility in Savage, Maryland. The Little Patuxent facility used dewatered cake lime stabilization for biosolids treatment. The changes to the biosolids processing included eliminating the lime system and replacing it with anaerobic digesters, centrate demmonification and associated solids screening, thickening, odor control and digester gas handling improvements.

After an extensive evaluation of phosphorous removal technologies, the design was based on AirPrex because of its demonstrated ability to prevent struvite precipitation in downstream processes, including piping and the solids dewatering equipment. The Little Patuxent facility uses decanter centrifuges for biosolids dewatering.The AirPrex process is a patented phosphorus recovery technology owned by CNP. AirPrex reduces problematic struvite buildup in wastewater treatment plants improving overall plant efficiencies, including dewatering improvements resulting in significant operational cost savings for treatment plants.

AirPrex’s flexibility was another factor in the design. The process either sequesters struvite, leaving it in the biosolids stream for land application on farm fields as fertilizer, or recovers struvite, separating it from the biosolids stream. Once separated, the struvite can be used as a beneficial slow-release fertilizer.
