Abstract (Summary)
Abstract This report is a work carried out for the company IDAB WAMAC International AB. The company is active within the business of mailroomequipment and is located in Eksjö (Sweden). The purpose of the work has been to be able to present construction principles for a new streamaligner that can manage a production velocity of 90 000 newspapers/hour. A streamaligner is a unit which is placed on, or integrated in, a conveyor belt and its purpose is to centre the newspaper flow on the conveyor belt after different steps of the production. The streamaligners of today do not correspond fully to the requirements and expectations of the printing companies regarding how well the newspapers centre, mostly at high production velocities. There are two types of streamaligners, the oscillating blade-aligner and the beltaligner. The oscillating blade-aligner centres the newspaper flow with the help of two blades that push the newspaper to the right position. The blades are performing an oscillating motion with the help of an excenter. The belt-aligner centres the newspaper flow with the help of vertical vibrating belts that are shaped narrowing to each other. To find out more about who the competitors are and what kind of streamaligner they have, a competitor analysis was carried out. With help of this analysis six main competitors were found, much thanks to the trade sector organisation IFRA: s homepage. In order to find out more about advantageous and disadvantageous with their streamaligners contact were taken with different printing companies. The answers from these companies were very poor so further investigations had to be made with the help of pictures and information from the internet and with help of the Swedish patent och registreringsverket. In order to evaluate and justify the choice of the function for the streamaligner, some of the fundamental reasons to the variation of the final outcome had to be studied, such as the friction between the newspaper and the conveyor belt and the linear momentum variation as a function of the production velocity.
