Vertical stacker

high-speed

More output space – the vertical stacker can accommodate up to 2,000 envelopes. With a handle the envelopes are ready for further processing and can e.g. be loaded in post boxes in one movement. The system has a maximum performance up to 27,000 envelopes/hour (depending of inserting system) and the stacking capacity is about 2000 packings, depending of envelope and content thickness. An intelligent monitoring is checking the run and reports when vertical stacker is full. More room at the exit, because the envelopes leave the inserter standing up instead of lying down. And that’s just what’s achieved by the vertical conveyor from Kern with a capacity of up to 2,000 envelopes – the operating effort at the exit area is reduced accordingly. As a result, clearing is much more convenient. The upright envelopes can be removed a lot easier and the stacks don’t have to be aligned. One simple interaction is enough and your letters are already in the mail tray. The most important feature of the new type of WRO / WRU is a new concept with spirals, targeted control of the feeder through thickness measurement, revised design as well as extended guides at the stacking belt. Benefits ■ Improved function with the new spiral concept (envelopes getting caught at the envelope windows is basically impossible). ■ Improved processing of envelopes with different thicknesses within the same job. ■ Almost no adjustment during operational phase thanks to thickness measurement even with envelopes of different thicknesses. ■ A marking device is available to separate the groups. ■ Increased stacking capacity (150mm) with consistent external dimensions.
