Erhardt+Leimer at Label Expo Europe 2023


    Erhardt+Leimer will exhibit new rotary drives and the new generation of the SMARTSCAN print image inspection system. Also on the E+L stand: systems and equipment for web guiding, web tension control and print monitoring. E+L specializes in automation and inspection technology and has an international sales and service network (booth D45, hall 4).

    New rotary drives and new possibilities for print inspection

    Erhardt+Leimer has recently added rotary actuating drives to its actuator product range. The motors of type AD 11 and AD 12 marketed under the EL.MOTION brand are “intelligent” drives with an integrated controller. Users can utilize the drives for position control, speed control, or torque control, making them particularly suitable for applications that prioritize quiet operation and long service life. The drive allows direct connection of two external limit switches. The combination of distributed intelligence with a dedicated interface concept enables the implementation of a decentralized drive topology, significantly reducing wiring and space requirements in the control cabinet. Erhardt+Leimer makes a wide range of communication standards available for these drives. The AD series comes with EL.NET technology, which allows control tasks to be implemented without any need whatsoever for an external controller. E+L has a large number of sensors and input/output modules available for this. All the drives come with web-based management on board as standard. When the motor is connected via Ethernet, users can address it through a PC’s web browser. This capability allows them to check and adjust settings or inquire about the current status of the motor. But that is not all: E+L also places great value on open connectivity and therefore also offers open access via Ethernet/UDP or certified standard protocols, such as Ethernet/IP, Profinet, and Powerlink.

    New generation of SMARTSCAN 200% print image inspection

    The new generation of SMARTSCAN can be installed in the familiar way on printing machines and rewinders. SMARTSCAN – or the MIS2 model to be more specific – is now faster and more compact, and it has a new design. On the variant with 2K resolution, we have already been able to achieve speeds of up to 600 m/min. But the 4K variant is catching up, and is now reaching speeds of up to 400 m/min. Faster LEDs and an optimized lighting concept deliver even better image quality. The reflection module, which displays reflective materials such as metal-coated materials or finishing foils (e.g., gold, silver), is now a standard inclusion. The same applies to the exchangeable background panel, which is advantageous for transparent materials in particular. With this package, users can trust that they are playing it safe in most areas. For example, in label or packaging printing. We have significantly reduced the height of the camera units. We preserved the standard functions, including integrated lighting on the rear panel and roller guidance.

    A new installation concept makes integration in the printing machine or the rewinder even easier.

    Previously, SMARTSCAN was available with a maximum width of 560 mm (22 inches), but with the latest generation E+L now also offers 660 mm (26 inches) and 760 mm (30 inches). Furthermore, we have optimized and expanded the software. New defect detection algorithms spot defects with even greater reliability. The same applies to the defect classification system, which assigns defects to categories such as missing label, unremoved matrix, print error, glue joint, or flag even more reliably than before. Further defect classes such as hole, barcode or incorrect length are also available. With all these options for capturing defects and errors, we can perform comprehensive evaluations to understand and optimize production processes. We will continue to use the tried and tested 200% inspection technology. Additionally, we have made improvements to detect hole defects and enhance the illumination of fluorescent materials. But special applications, such as the production of labels with integrated RFID antennas, will also benefit from the new features.
