Method and device for controlling the setting of the components of a printing and cutting machine
First Claim
1. In a machine having a plurality of components operable on a web having registration marks thereon, said components arranged in respective stations of a machine through which said web moves, said stations including a printing station with a first motor therein for correcting length registration of a print on said web and a second motor therein for correcting lateral registration of a print on said web, a cutting station having a third motor therein for correcting length registration of a cutting operation on said web and a fourth motor therein for correcting lateral registration of said cutting operation on said web, an apparatus for controlling the setting with respect to said web of each of said components comprising:
- means for detecting information identifying a current operational and positional status for each of said components;
means for converting said information into respective electronic signals;
means for storing said signals;
means for converting the stored signals into graphic and alpha-numeric data;
a computer having a touch screen on which said graphic and alpha-numeric data for each of said stations is displayable, said computer having means for supplying control signals for the setting of each of said components by manually contacting selected data displayed on said touch screen;
wherein said means for detecting information includes in said print station at least one read head disposed for reading said registration marks on said web;
a fifth motor mechanically connected to said read head and electrically connected to said means for supplying control signals for laterally shifting said read head in response to one of said control signals;
a roll in said print station over which said web passes and a pulse generator means connected to said roll for providing a pulse train corresponding to the angular position of said roll;
an interface processor connected to said means for detecting information, including connection to said pulse generator, to each of said stations, and to said computer;
at least one first motor control microprocessor connected to said fifth motor and connected to said interface processor and to said pulse generator;
at least one read microprocessor connected to said read head for receiving registration information therefrom;
a second motor control microprocessor connected to said first motor in said printing station;
a third motor control microprocessor connected to said second motor in said printing station;
a fourth motor control microprocessor connected to both said third and fourth motors in said cutting station; and
a bus which is part of said means for supplying control signals connecting each of said microprocessors to said computer to permit setting of the motors in said stations via said computer by said contacting of said touch screen.

Abstract
A method and apparatus for controlling the setting of the components of a printing machine use a calculating unit which receives all of the data regarding the operating status of each of the components to be controlled. The calculating unit process data relating to the running of the web and compares the data with data obtained by read heads, also sensing the web. The data from the read heads is supplied to the memory of a computer, the computer also having a touch screen for permitting direct control and setting of the components. A printer and a photographic recorder are coupled with the touch screen for displaying the images thereon.
