Method for storing rolls of material

A method for storing unprepared rolls of material and prepared rolls of material for use in roll changers in a web-fed rotary printing machine including:

• providing a stock reception area;
• receiving rolls of material for use in said web-fed rotary printing machine in said stock reception area;
• providing a depot for receiving rolls of material from said stock reception area;
• providing a defined number of roll storage spaces in said depot;
• locating selected ones of said roll storage spaces in said depot adjacent said web-fed rotary printing machine;
• providing a roll preparation circuit and using said roll preparation circuit for preparing rolls of material for use in said roll changers;
• transferring prepared rolls of material from said roll preparation circuit and unprepared rolls of material from said stock reception area to separate ones of said defined storage spaces in said depot;
• providing a material flow system for said web-fed rotary printing machine;
• providing an implemented logic device for managing said material flow system;
• providing said material flow system with production-relevant data for a planned production run of said web-fed rotary printing machine;
• providing a depot management system in said depot and having knowledge of properties of said prepared rolls of material and said unprepared rolls of material located in said ones of said defined roll storage spaces in said depot;
• determining, in a first partial process of said material flow system, a production-oriented storage strategy for using said rolls of material located in said storage spaces in said depot using said production-relevant data for said planned production run;
• checking, in a second partial process of said material flow system, information on said occupancy, in said ones of said defined storage spaces in said depot of said unprepared rolls of material and said prepared rolls of material located in said defined storage spaces;
• using said production-oriented storage strategy and said information on said positioning of said unprepared rolls of material and said prepared rolls of material in occupancy in said depot and repositioning said rolls of material in said depot for optimizing delivery of said prepared rolls of material from said depot to said roll changers of said web-fed rotary printing machine during operation of said web-fed rotary printing machine by positioning said prepared rolls of material in said selected ones of said depot roll storage spaces adjacent said web-fed rotary printing machine and for optimizing preparing of previously unprepared rolls of material for their preparation and subsequent delivery to said roll changers of said web-fed rotary printer machine as prepared rolls of material from said depot, by positioning said unprepared rolls of material in other ones of said depot roll storage spaces, all in accordance with said production-oriented storage strategy;
• and
• delivering said prepared rolls of material from said depot to said roll changers of said web-fed rotary printing machine using said material flow system.
