Piab has upgraded its flagship product \u2013 the piCOMPACT\u00ae vacuum ejector series \u2013 to support Industry 4.0 functionality. Enabling connectivity between devices through IO-Link, adding sensors to collect valuable process information and analyse such through integrated intelligence makes vacuum handling not just smarter but safer at the same time. Enabling predictive maintenance was a key driver for this development because it increases machine up- and lifetime, speeds up the maintenance process and reduces costs.<\/p>\n\n\n\n

Predictive maintenace is usually defined as monitoring performance and condition of equipment during normal operations. This implies that simply providing a highly efficient, reliable and small enough to integrate vacuum ejectors is no longer enough. Vacuum ejectors powering robotic gripping systems such as suction cups, foam grippers etc. for pick and place applications common e.g. in automotive press shops are the interconnection between the gripping unit and the robot and can provide insights into both sides to ensure a smooth-running system. When digitizing their flagship product to a smart version, the Piab R&D team therefore put a lot of emphasis on supporting the requirements of predictive maintenance to increase their customers\u2019 competitiveness. The\u00a0piCOMPACT\u00ae23 SMART\u00a0ejector combines state-of-the-art technology to keep systems up and running at the maximal possible level.<\/p>\n\n\n\n

Connectivity enables communication with other devices and the cloud through an IO-Link. Offering fieldbus-independence, IO-Link is a further development of existing, tried-and tested connection technology for sensors and actuators. It offers automated parameter setting and enables operators to read and write parameters for various features even during operation. Such a degree of process overview in real-time means that many potential issues can be dealt with before they have any real impact on the production. The opportunity for system diagnosis allows problems to be identified and corrected more easily and quickly. This has the potential to lead to greatly improved productivity. One of the key factors behind this diagnostic ability is that, contrary to conventional technology, IO-Link offers a data storage function. This enables operators to quickly establish if and why a device or operation might have failed during, for instance, an over-night run. It makes it possible to identify the cause of a failure; perhaps a faulty device needs to be replaced, or the culprit might simply be an incorrect electrical connection. Additionally, if a new, identical substitution device is connected, the parameters of the previous device are automatically transferred saving on precious installation time.<\/p>\n\n\n\n

Big data analysis requires measurements of various characteristics to generate the information that can be analysed and used for system optimization. Sensors enable the collection of information that can be used to improve productivity and reduce downtime, facilitating condition monitoring and predictive maintenance. This led to several sensors being added to the system measuring direct operation characteristics of the vacuum ejector for quick detection of potential operational issues such as leakage in the system, the ejector not running well for enabling predictive maintenance. Users can set trigger points and when data deviates and passes such a trigger point, it is an indication that maintenance will be needed soon. This allows preparation, the exchange of only few parts and avoids unforeseen production line shutdowns.<\/p>\n\n\n\n

Therefore, Piab\u2019s R&D team decided to equip piCOMPACT\u00ae23 SMART directly with several diagnostic sensors that support predictive maintenance measuring system temperature current, system voltage, acceleration, cycle counter and system self-check features. Changes in these can indicate that something else is broken in the robot cell or plant. Hence, piCOMPACT\u00ae23 SMART helps to monitor the whole automation systems and prevents any issues with connected or surrounding equipment in addition to increased understanding of how the ejector itself is running.<\/p>\n\n\n\n

A sensor shows the real operating temperature to ensure fast information in case it moves out of this range, which may indicate problems in the closer environment of the ejector. This feature was integrated on the one hand to increase the ejector\u2019s lifetime and ensure its optimal operation but also as an easy to detect warning signal that there may be issues with other system devices that causes temperatures to rise. A voltage sensor controls the power input and determines the operational status. This feature was added to support users in avoiding damages to the system due to low power and increase the overall systems lifetime. Low power \u201cvoltage\u201d in function and warnings are given.<\/p>\n\n\n\n

An important parameter to predict maintenance of vacuum-based robotic gripping systems is to keep them clean. Especially in dusty applications where vacuum filters will contaminate over time, which leads to unwanted vacuum pressure drops that slows down the process or even starts to give false signals. A way to monitor this is to keep control of the vacuum system\u2019s built-in pressure drop level, or as it is named in the piCOMPACT\u00ae23 SMART; the Free-running Vacuum Level (FVL). When and if the FVL starts to drift from its initial status, the Fresh Free-running Vacuum Level (FFVL) of the system is starting to clog.<\/p>\n\n\n\n

Another way to predict maintenance from the beginning to a leak in a vacuum system, e.g. damaged tubing, fittings or a broken suction cup, is to track the time to evacuate to a certain vacuum level. The piCOMPACT\u00ae23 SMART refers to its function First Time To Hit (FTTH) in a fully functioning vacuum system which measures the fastest evacuation time from the Fresh Free-running Vacuum Level (FFVL) and further down -15 kPa deeper in vacuum. When and if later cycles use longer time to evacuate to the same level (-15 kPa ), monitored and logged as Time To Hit (TTH), the system most likely suffers from leakage and needs service.<\/p>\n\n\n\n

With an eye on the automotive industry with its high degree on automation and handling of large and heavy parts safety of operations plays an important role when the machines are running as well as when maintenance takes place. This led to the development of separate power domains for actuators and sensors. Such systems allow activation of the sensor power separately by the operator for maintenance or trouble shooting in the robot cell while leaving actuators disconnected from power supply, so operators are not endangered by moving parts in case e.g. of a short circuit. The advantage of the separate power domains is that it allows the use of compact style ejectors without separate valve stations. This reduces the cost of installation \u2013 as does the fact that usually expensive workarounds or add-on modules to compact ejectors are not required.<\/p>\n\n\n\n

A second safety feature developed is a complementary bit or PDO (process data output). This needs to be enabled to activate vacuum or blow, in addition to the ordinary vacuum or blow signal. It also avoids a \u201ctoo quick\u201d vacuum on signal creating a risky situation if the rest of the program is not yet fully up and running or communicating.<\/p>\n\n\n\n

Making predictive maintenance feasible the piCOMPACT\u00ae 23 SMART ensures high machine up-times not only for the vacuum system itself but for the whole automation system as it monitors a wide a range of environmental conditions that influence the systems performance.<\/p>\n\n\n\n
