Creating a system that monitors in real time the amount of newspaper coming into the mailrooms.

Abstract

The aim of this thesis was to create a new system that monitors in real time the amount of newspaper production that goes into the mailroom and select the best sensors, counters and in order to improve the accuracy of the machine. The purpose was also to optimize the stoppage of the press and to reduce wastage. Saving cost, maximising profit and making decision easier. The thesis was commissioned by Alma Manu Oy maintenance department in Tampere. In spring 2011, Alma Manu Oy decided to improve on their printing accuracy and level of wastage. And in order to achieve this, the right sensors and counters must be duly considered. The existing technology then only allowed for a total net count of the printed papers right from both control rooms. The printing machines are two with two control rooms in which the printings are being monitored. Several meetings were held with the maintenance engineer, machine oper- ators and maintenance manager prior to the commencement of the project in order to know the exact approach to use in realising the desired result. The printing machine name is Rowland colour man a machine which runs on different conveyers, frequency converters, and gripper conveyers lines.
