What makes sensors the most important components of smart machines?

wenglor’s new promotional video provides answers to this exciting question. Development director Dr. Alexander Ohl takes viewers of a visionary journey into the future of the automation sector and explores interesting facets of the innovative family company. From daring product visions and digital corporate processes, right on up to fully networked production systems, spectators discover everything about the present and the future of intelligent sensors, as well as image processing and safety products. But see for yourself ...

Intelligence, Performance and Compact Design for Intralogistics

Optical sensors from wenglor, which are as small as a sugar cube, make it possible to control transport shuttles in intralogistics systems. In order to regulate clearances and prevent collisions, the sensors have to be integrated into mobile robots, for which only minimal space is available. wenglor’s P1KY10x is one of the smallest, and at the same time one of the highest performance transit time sensors on the market.

In addition to already successfully established sensors from the P1KY00x product range (32 x 22 x 12 mm, 1 kHz, red light, 1000 mm), the new P1KY10x transit time sensors assure more flexibility, especially in the field of intralogistics: with an even smaller housing which measures just 32 x 16 x 12 mm, a switching frequency of 10 Hz, infrared light, a previously unparalleled working range of 0 to 1500 mm, an IO-Link interface and two mutually independent switching outputs, the sensor implements a diverse range of tasks where shuttle motion is involved – and it’s cost-efficient to boot. Regardless of whether clearance checking or shelf-occupied enquiries are concerned, shuttles are rendered even more intelligent by the additional sensing options: so-called slow-stop circuits cause the shuttle to slow down upon reaching the first switching point – thanks to the two independent switching outputs – and come to a full stop upon reaching the second switching point, for example when another shuttle has blocked the travel path. Alternatively, speed can be controlled directly via measured clearance values.

All settings can be conveniently entered via the central controller with the help of the IO-Link interface, which is a tremendous advantage in light of the enormous dimensions of logistics centers. Measured values and process parameters can be easily read in via the IO-Link interface as well. “With a switching distance of up to 1500 mm, this extraordinary transit time sensor offers outstanding performance”, explains wenglor product manager Christoph Lang. “Together with the two switching outputs, a minimal housing size and IO-Link technology, this makes the P1KY10x unique around the world.”

Pure Dynamics: Safety Light Curtains Protect Window Production

As German machinery manufacturing experts for window production lines, Urban GmbH & Co. Maschinenbau KG relies on wenglor’s type SEMP safety light curtains in order to secure moving system components. For fully automated welding of plastic window frames of various sizes, the system components have to be as mobile as possible during operation – and at the same time fully secured.

wenglor’s safety solution was especially convincing due to simple adjustment, compact dimensions (3.4 cm wide by 2.8 cm deep) and easy integration into the overall system. “In addition to the basic functions, SEMG light curtains can also be precisely aligned thanks to visible red light and diagnosis LEDs, even when they’re mounted very close to each other”, explains wenglor sales manager Andreas Pfleghaar. “Furthermore, our products are so accurate that they can move towards or away from each other dynamically – even during operation – and reliably secure their respective zones over a distance of several meters.”

Two sets of SEMG safety light curtains were used to install intelligent, dynamic zone security. And thus the safety light curtains can be moved during operation without opening any of the three safety zones. Smart: If someone enters the left or right safety zone, the other continues operation unhindered. If the middle zone is entered, both are shut down.

Transparent Labels Made Visible – with the Ultrasonic Fork from wenglor

Perfect product labelling plays an important role in packaging processes, because packaging errors are perceived as a product defect. That’s why companies count on wenglor’s ultrasonic fork sensors in their packaging systems. They reliably monitor the presence of dark, transparent or printed labels on the role holders, before they’re applied to the packages by the label dispensers. And thus they assure highest possible quality standards and, at the same time, reduce costs which results from scrap due to incorrectly labelled products.

In fully automated packaging systems with high throughput rates, the ultrasonic sensors even reliably detect transparent labels on transparent base materials. This unparalleled precision is based on their functional principle. “Ultrasonic fork sensors detect labels on the basis of attenuation of the emitted ultrasonic signal which varies depending on the thickness of the material. Labels on the base material attenuate the ultrasound to a greater extent that the bare base material between any two labels. As a result, color, degree of transparency and the surface characteristics of the labels have no influence on the results”, explains wenglor product manager Martin Knittel. Sensor performance is convincing as well: a small gap of two millimeters is already enough to reliably detect labels at a switching frequency of up to 400 Hz.
