Modular machine concepts effectively address two of the many challenges the material handling and packaging industry is currently confronting: improving efficiency and reducing downtime. One of the quickest, easiest, most economical, and most accessible ways to leverage modular machine concepts is to employ devices compatible with IO-Link. This article introduces IO-Link and its many advantages, explains how it can help improve the modularity, efficiency, throughput, and uptime of material handling and packaging machinery, and introduces IO-Link devices from leading suppliers in this industry.  <\/h3>\n\n\n\n

The material handling and packaging industry is currently contending with consumer and market pressures that are driving the need for manufacturers to improve efficiency, reduce equipment downtime, become more sustainable, and comply with evolving regulatory standards. This complex mix of challenges will require numerous solutions. But one solution \u2014 modular machine concepts \u2014 effectively addresses both efficiency and downtime demands.<\/p>\n\n\n\n

Modular machine concepts make it quick and easy to retrofit machines, which allows users to support multiple processes, as well as scale production with the integration of new machines. One of the quickest, easiest, most economical, and most accessible ways to leverage modular machine concepts is to employ devices compatible with the IO-Link communications protocol, which has exploded in popularity since it was standardized in 2006.<\/p>\n\n\n\n

The IO-Link communications protocol is an open standard serial communications protocol that uses a simple, fieldbus-agnostic master\/device architecture to enable bidirectional data exchange between compatible sensors and devices connected to an IO-Link master. IO-Link masters<\/a> transmit data over various networks, fieldbuses, and backplane buses to make that data accessible by PLCs and HMIs in real-time, which operators can use to perform both immediate actions and long-term analysis.<\/p>\n\n\n\n

IO-Link devices<\/a> offer multiple advantages valuable to owners and operators in the material handling and packaging industry. They support modularity and interoperability, standardize and reduce device and equipment wiring requirements and costs, acquire and transmit actionable data, enable remote configuration and monitoring, simplify device replacement and equipment retrofits, and provide detailed diagnostics.<\/p>\n\n\n\n

Like many elements of the modern manufacturing industry, today\u2019s material handling and packaging processes are increasingly automated. IO-Link devices inform operators about what they\u2019re doing and how well they\u2019re doing it by instantly identifying and communicating any issues. This gives users incredible insight into and control over their sensors, which can improve process efficiency, reduce equipment downtime, increase production, and enable data-driven decision-making. In addition, material handling and packaging equipment often requires frequent changeovers to safely, effectively, and efficiently handle and package a variety of different products. So, the improved efficiency and reduced equipment downtime enabled by IO-Link devices can be a real game-changer.<\/p>\n\n\n\n

For these reasons, IO-Link is now the fastest-growing sensor and actuator interface in the world. In 2013, there were less than two million active IO-Link devices. Today, there are over 28 million IO-Link devices, and the IO-Link Consortium<\/a>, which governs the protocol and ensures device interoperability (that any IO-Link device will work with any IO-Link master), has grown to include more than 400 core user companies and leading global automation suppliers, including Banner Engineering<\/a>, Phoenix Contact<\/a>, Norgren<\/a>, Leuze<\/a>, SICK<\/a>, and Siemens<\/a>. Further, demand is still increasing. IO-Link devices are expected to experience a 20% year-over-year CAGR for the next several years.<\/p>\n\n\n\n

The vendor-agnostic interoperability of IO-Link devices enables extensive modularity and is one of the primary reasons behind the technology\u2019s meteoric rise. IO-Link devices are standardized on M12 connectivity. So, while adopters switching from traditional I\/O systems with wire-based connections to an IO-Link system standardized on M12 connectivity will have to contend with an upfront investment, IO-Link systems require far less wiring and much quicker and easier to install. As such, the total cost savings enabled by not having to connect every individual sensor, actuator, and other device wire to a PLC, in addition to the cost savings enabled by slashing wiring installation and maintenance times, typically compensates for that initial investment in a short amount of time. In fact, Sean Foley, a Global Product Manager at Banner Engineering, said that he’s seen OEMs achieve 15\u201320% savings<\/a> on both hardware and installation costs when going from a standard I\/O system to a modular IO-Link system.<\/p>\n\n\n\n

RS offers a variety of IO-Link solutions ideally suited for modernizing industrial automation applications<\/a> in the manufacturing, material handling, and packaging industries by making them more modular.<\/p>\n<\/div>\n\n\n\n

Banner Engineering\u2019s Q5X Series laser measurement sensors<\/a> have a self-contained, IP67-rated form factor with dual independent output channels and IO-Link capabilities that support plug-and-play modularity. They are also available with an optional remote sensor display (sold separately) that enables remote programming and monitoring.<\/p>\n\n\n\n

Banner\u2019s Q5X Series sensors are easy to install, set up, and troubleshoot, which reduces installation costs, They also have bright output indicators for real-time distance feedback, which helps reduce equipment downtime. Unlike traditional measurement sensors, which rely on gaps between packages to identify packaging process jams and are subject to identification delays, the Q5X Series laser sensors have a 5,000mm measurement range and exceptionally high excess gain. This allows them to reliably detect a range of colored objects, including extremely dark targets (e.g., <6% reflective black targets), black targets against black backgrounds, black targets against shiny metal backgrounds, clear and reflective targets, and multicolor targets.<\/p>\n<\/div>\n<\/div>\n\n\n\n

These features enable proactive package jam identification and reduced package spacing for increased throughput. They also reduce false positives, eliminate excessive identification delays, and improve detection accuracy. Ideal material handling and packaging application areas include conveyor power curves, gravity-fed spire conveyors, and non-singulated bulk flow parcel flows. The Q5X Series is also ideal for activities like food pallet presence detection, end-of-line pallet detection, shrink wrap detection, carton full\/empty identification, case packing, flexible packaging and pouch filling applications, clear bottle detection, depalletizing, bottle counting and sorting, quality control, filling and capping, and conveyor cleaning.<\/p>\n\n\n\n
