SICK doesn’t just offer products – it also offers the expertise and high standards required for these products to make a valuable contribution to protecting the environment on a worldwide scale. In this respect, it’s the countless little ideas and developments that arise from working closely with customers to come up with solutions in different applications that really make a difference. These innovations show the many possibilities offered by sensors in production processes alone when it comes to sustainability.
Greater efficiency and better quality in packaging processes thanks to controllable, sustainable, and trouble-free production around the clock: The DeltaPac is perfectly capable of differentiating between objects in a continuous flow of materials. Mechanical singulation and packaging buffers between two machine components are not required. The DeltaPac allows you to wave goodbye to many of the issues commonly found in packaging processes, including collisions and product blockages arising due to fallen packages, incorrect alignment of labels or drinking straw applicators, inaccurate packaging group allocations, and deviations in quantities on pallets.
Saving material in the labelling process
In the labelling process, SICK employs a new kind of technology in the form of the ML20 markless sensor. The special feature of this is that the sensor used to position the labels is able to function without the colored marks normally required, offering a saving of up to 5 percent on materials for each label. In mass applications within the packaging industry, that means that up to 1.5 million meters of label material can be saved annually on each system.
Technical innovation reduces cable requirements by half
With the HIPERFACE DSL® digital interface, SICK has developed a purely digital protocol that uses a minimum of connection cables between the frequency converter and motor feedback system. This “digital servo link” interface enables an entirely new architecture for servo drive systems with completely new options, as it is now purely digital instead of hybrid (analog/digital). In motor-controller communication applications, the cost and effort of cabling is reduced by half. As far as the packaging sector is concerned, the size of this innovation is particularly clear: For around 300,000 servo drives that are installed in packaging machines every year with an average motor cable length of 5m, HIPERFACE DSL ® saves approximately 1.5 million meters of cable.
Motor feedback systems for controlled drives
Market research conducted by Quest TechnoMarketing suggests that the use of electronic – particularly controlled – drives in machines will increase significantly until 2016. In addition to a rise in functionality, the higher levels of energy efficiency associated with controlled electronic drives in particular is a key factor for this trend. With today’s energy prices, the potential savings to be made by using controlled drives and efficient motors can generally be seen in under two years – and in most cases significantly earlier. The effects on the environment are positive: Savings of 135 billion kWh and 63 million tons of carbon dioxide (CO2) are expected across the EU by the year 2020 as a result of using more efficient electric motors. SICK plays an active role in supporting this positive development with its motor feedback systems, which are specially adapted to suit synchronous motors:
