Schmalz’s SCPS, SCPSi ejectors

Automatic blow-off function

The new ejector series SCPS and SCPSi from Schmalz with nozzle sizes from 0.7 to 1.5 mm raises the bar for efficiency in automation

Compact design, high performance, intelligent integrated functions – the new ejector series SCPS and SCPSi from Schmalz with nozzle sizes from 0.7 to 1.5 mm raises the bar for efficiency in automation. The ejectors are used in a number of different industries including packaging, metal, plastics, glass and solar power.

At just 18 x 105 x 99 mm and with a suction rate of 65 litres a minute and a pressure range from two to six bars, these compact solutions are suited for handling suctiontight and slightly porous workpieces. This makes them perfect for use in systems with limited space and highly dynamic processes with demanding requirements.

Schmalz has equipped the SCPS and SCPSi compact ejectors with more functions than comparable ejectors of similar size. The vacuum specialist has also optimized the series in
terms of fluid technology. High-performance nozzles ensure that the ejector can generate an extremely high vacuum in the fraction of a second. Together with very fast valve switching times, the high performance levels of the new series ensure extremely short cycle times for applications up to well over 200 cycles a minute. Moreover, the ejectors are also equipped with an automatic air saving function for economic operation. This reduces the amount of compressed air consumption by up to 80% compared to similar ejectors without controllers, which also reduces operating costs. If no vacuum is required at a given moment, this function is simply switched off by the compressed air generator. At the same time, it permanently monitors the vacuum level and reacts immediately to extreme drops.

In order to adapt the ejectors optimally to the workpiece and to the process, Schmalz has equipped them with an automatic, strength-adjustable blow-off function. This allows for even quicker pick-up of parts and increases the overall dynamics of the process. The particularly user-friendly display is one of the features of the compact ejectors. It provides the operator with information about the most important vacuum parameters at a glance. At the same time, large buttons and a clear menu structure make it easy to operate. With the standard IO-Link interface of the SCPSi the operator can perform parameterization and diagnostics on the ejector from the central system controller.

The SCPSi ejectors also feature an integrated condition monitoring function. This function continuously measures and monitors the leak-tightness and the vacuum level of the vacuum system. The operator can recognize errors early on and can fix them before they lead to system downtime. The vacuum generators measure all of the important energy and performance data and communicate it to the higher-level field bus systems viathe existing IO-Link master. This allows the system operator to read out, monitor and optimize the data in his or her control system. This reduces energy consumption, increases system availability and makes it possible to design the system based on performance. Also, the compact and durable unit can be installed directly on the handling system. This simplifies installation and creates more space.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.

In an admittedly fragmented and textured terrain, this is the right time to plan your participation and marketing support communication – in our impactful and highly targeted business platform.
