Abstract

A method for displaying machine malfunctions, particularly for polygraphic machines such as large printing presses, provides concrete instructions for quickly finding and eliminating these machine malfunctions without it being necessary to consult a machine handbook. With the occurrence of a malfunction, an actual image or a series of actual images of the machine is/are displayed on a monitor of a machine control console for effective guidance to the source of the malfunction. Instructions for eliminating the respective malfunction are also displayed.

Claims

1. A method for displaying malfunctions of a large printing press, which employs visual and acoustic indications of malfunctions, said method comprising the steps of:

a) supplying at least one signal indicative of a printing press malfunction from at least one malfunction indicator to a program in a stored-program control mechanism;

b) generating a malfunction number in response to said at least one signal, said malfunction number corresponding to the malfunction indicated by said at least one malfunction indicator;

c) feeding said malfunction number to a computer, said computer including a video storage medium and a computer monitor screen;

d) accessing at least one of a plurality of video images stored in said video storage medium, said accessed stored video images being allocated to said malfunction number, each of said stored video images being an actual video image of an element of the printing press to be monitored, each such actual stored video image showing a location on the printing press of the printing press malfunction; and

e) displaying said at least one of said plurality of actual stored video images of said element of the printing press on said computer monitor screen for use in guiding an operator directly to the location of the malfunction and for use in guiding an operator in eliminating the respective malfunction.

2. The method of claim 1, wherein the step of generating a malfunction number further comprises feeding at least one signal from said at least one malfunction indicator into a stored-program control mechanism and employing a program in said stored-program control mechanism to generate said malfunction number from said at least one signal.

3. The method of claim 1 further including displaying a series of said plurality of said stored video images in a sequence and using said series of displayed video images for guiding an operator in localizing and eliminating the malfunction in the printing press.

4. The method of claim 1 further including providing each of said plurality of stored video images of an actual element of the printing press by means of a video camera and a video digitizer, said video digitizer digitizing video images produced by said video camera and storing said video images in memory.
