world pulppaper 95 Less roll bouncing also means less friction and roll spinning and accordingly a reduction of paper cuts and tears weight. This leads to two problems First the energy consumption is very high. Second due to the increased roll weight units that at one time were oversized are now undersized and this causes high maintenance requirements. New ideas supported by tekes In 2012 MoveRoll started to consider new alternatives to the traditional methods in the hope of developing better ways to cushion rolls whilst saving as much energy as possible. During the R D process funded by TEKES The Finnish Funding Agency for Innovation we tested several methods some of which had commercial potential to learn how receiving processes could be improved. Based on the test results we found that the best solution comprised two- level absorbing sections. We have introduced the MoveRoll Zero Energy Receiver ZER as a replacement to fixed steel stops and developed a new philosophy to mechanical receiving that emphasises safety simplicity cost efficiency and low energy consumption. Even if ZER-receivers look simple it has been a challenging and difficult process to find the correct solution and technology which can be adapted to different paper roll sizes different roll weights and different paper qualities comments MoveRolls CEO Mikko Rantanen. absorbiNg kiNetic eNergy ZER-Receivers have been developed for low-frequency roll handling applications. They are very simple constructions and low-cost solutions that do not need to be connected to any energy sources. The unique receiving method uses self-inflating energy absorbers with adjustable energy absorbing capacity. This way most of the roll dimensions and widths can be handled with care. Compared to steel stops the most significant benefit of the new receiving solution is that the energy actually is absorbed while steel stops cause rolls to bounce back to the deck and eventually slow down through friction. This absorption of energy means two major improvements for the roll receiving process first and most importantly increased workplace safety. Secondly a reduction in paper roll damage. The improvement in safety is due to the energy absorbing function of ZER-Receivers which prevents paper rolls from bouncing back and forth heavily. This is especially relevant for applications where operators are working on decks. Winder decks are typical examples of this. Less roll bouncing also means less friction and roll spinning and accordingly a reduction of paper cuts and tears. Furthermore with ZER-Receivers paper rolls only ever touch the self-inflating energy absorbers by having no contact with the steel plates damages to paper rolls are further reduced. Figure 1.
