JPS6411834A - Totaling device for totaling inputs of working condition of printing machine - Google Patents

Abstract

PURPOSE:To make it unnecessary to provide a new relay sequence even upon facing the change of the kind of a printing machine, by providing a calculating means to obtain a signal indicating the working condition of the printing machine according to calculating program stored in advance with respect to a control signal outputted from the printing machine. CONSTITUTION:There are such control signals 2 as a stop signal, a slight move signal, a slow move signal, a cylinder insertion signal, a high-speed signal, a low-speed signal or a counter signal, etc., that are given by a control unit of a printing machine 1. These signals are changed into signals indicating the working condition of the printing machine through the voltage level conversion, and the logical conversion when they are inputted into an input signal interface 3 of a microcomputer A. More specifically, the level of the voltage is converted in a relay BOX 2A, while the logical conversion is carried out in the microcomputer A of a system 8. The resulting software is included in ROM 4 of the microcomputer A. When the control signal 2 is converted into a signal indicating the working condition, supporting that the logical functions with respect to logical converting parts are f1, f2,...fn, those with respect to n control signals are I1, I2,...I and those with respect to m working condition signals are O1, O2,...O, the logical conversion at mth time is Om=fm (I1, I2,...In).
