Automation and quality assurance at the K fair
Erhardt+Leimer at K 2019
All current E+L components are 'IoT 4.0-ready,' i.e. suitable for integration into the latest generation of production systems. Each of the devices manufactured in large numbers, whether it is a sensor, a web guider or a high-precision linear drive, can be connected both actively and passively to digital networks. E+L technology therefore integrates perfectly into the production and/or ERP systems of the users to make automated and documented manufacture possible. Device and system data of E+L products can be backed up and restored if required. The high performance products offers both direct and remote access to the service team and can be functionally expanded in a simple manner via the Data Master or PLC.
The latest generation components with integrated web server and intuitive administration via browser support the technical staff in achieving continuous and optimized production. This is done primarily with the integrated high-tech analysis tools, which can be used directly without additional software. This reduces or completely avoids downtimes and ensures quality in a sustainable manner.
A highly dynamic, maintenance-free actuating drive
The AG 9 is the first actuating drive developed entirely by E+L. The device was primarily designed for web guiding systems, however in principle it can be used in all applications that require a maintenance-free, highly dynamic linear drive with a large actuating force.
In combination with the command station DO 3001 or DO 33, the AG 9 is used for web guiding on unwinders, winders and in large pivoting frames. Ethernet networking with response times of 1 ms and an actuating speed of up to 60 mm/s ensure maximum actuating dynamics. Even at high reel weight, that allows optimal compensation of tumbling errors, for example. Control frequencies up to 4 Hz are possible.
The AG 9 is the only fully integrated actuating drive on the market with a brushless and therefore wear-free motor. The position is acquired via an integrated absolute encoder – this is also a unique feature. That means that no reference run is required on commissioning, and the current position of the actuating drive is not lost even if the power fails. The controller is also integrated in the actuating drive.
As the AG 9 is a direct drive without gearbox, it is almost play-free in the axial direction. The device itself is highly compact, allowing it to be mounted even in tight spaces.
The DO 33 command station with touch technology assists operators by means of the integrated graphic user interface with a graphic commissioning wizard and offers additional web functionality for expert settings and service.
Print image monitoring for the highest requirements
ELSCAN OMS6 is a video system for operating widths of up to 3,250 mm that meets very high demands on the image quality. It features a large field of view of 234 x 124 mm and an LED flash and can be optionally equipped with a varnish flash, UV flash and different rear flashes. The camera navigation is of high precision and extremely dynamic. All ELSCAN web monitoring systems use the dualView technology patented by E+L, i.e. two cameras with fixed focal lengths, which are combined in a shared housing. One camera shows a large repeat area (wide-angle lens), while the other camera shows the smallest details (telephoto lens). The section of the image from the telephoto camera is in the center of the wide angle camera. During digital zooming, the camera switches imperceptibly between the two cameras to enable your print image to be displayed with a multiple of the print resolution. This special technology allows high-resolution images of different repeat sections to be displayed without a time delay.
ELTIM layer thickness and weight per unit area measurement
ELTIM allows for the contactless measurement of layer thickness, weight per unit area and other material properties across the entire web width, in this way enabling complete quality assurance for a wide variety of films and composite materials. The measurement is done using ultrasound, without the need for complex system calibration. The measuring accuracy is up to 0.5 % of the measured value.
