Abstract
Process for feeding paper rolls for supplying web-fed rotary presses with paper rolls and for disposing of remnants from web-fed rotary presses, comprising a control system, which stores data on the location and the type of all paper rolls and disposal containers at any point in time. The system is designed to be so redundant such that partially manual or completely manual operation is possible in the case of failure of one or several components, as a result of which printing of the jeopardized publication is possible even in case of emergency, and the safety and ergonomic aspects are also not neglected even in an emergency situation.
Claims19
A process for feeding paper rolls to web-fed rotary presses, in which each paper roll is brought from a main roll stockroom used for long-term storage to a roll stand of the web-fed rotary press, comprising the steps of:
- providing paper roll sites in an intermediate roll stockroom;
- conveying paper rolls from the main roll stockroom to the intermediate roll stockroom via a first conveying device to reach a zone of action of a second conveying device;
- providing said second conveying device in the form of an overhead crane system for freely accessing said paper roll sites;
- prior to reaching said zone of action of said second conveying device reading information in the form of indicia provided on the paper roll via a data acquisition device for storing data of the paper roll including roll weight, basis weight and paper grade along with coordinates of the site of the intermediate roll stockroom determined for the roll, said site being freely and selectively accessible by said second conveying device;
- moving a paper roll from said zone of action by said second conveying device to said determined site of said sites of the intermediate roll stockroom including engaging the paper roll with the crane system at said zone of action, moving the crane system and paper roll above said sites of the intermediate roll stock room to said determined site and depositing the paper roll at said determined site;
- subsequently transferring the paper roll from the determined site to a roll cart system via said second conveying means including engaging the paper roll with the crane system at said determined site, moving the crane system and the paper roll above said sites of the intermediate roll stock room to said roll cart system and depositing the paper roll in a roll cart of said roll cart system;
- and, subsequently moving the roll to one of an unpacking and bonding preparation station and a roll stand via said roll cart system.
A system for feeding paper rolls to web-fed rotary presses comprising:
- a main stock room;
- an intermediate roll stockroom including a plurality of paper roll sites;
- a roll stand;
- roll remnant disposal means including a roll remnant disposal station for disposing of roll remnants;
- first roll conveying means for conveying rolls between said main roll stock room and said intermediate roll stockroom;
- unpacking and bonding preparation station;
- an unpacking and bonding area adjacent said intermediate roll stock room, said unpacking and bonding preparation station being located in said unpacking and bonding area;
- and a printing press area adjacent said unpacking and bonding area, said roll stand being located in said printing press area;
- roll cart means extending from said intermediate roll stock room through to said unpacking and bonding area to said roll stand in said printing press area;
- free access transportation means located in said intermediate roll stock room for transporting a paper roll from said first roll conveying means to a determined site of said plurality of paper roll sites, said free access transportation means moving the paper roll above said sites of said intermediate roll stock room to allow free access to said sites;
- and, control means including a data acquisition device located adjacent said first roll conveying system for receiving data on the paper roll including weight, paper grade and the position coordinates of the site of the intermediate roll stockroom determined for the roll and for controlling movement of the paper roll.
A roll feed room for web-fed rotary presses, comprising:
- a main stock room;
- an intermediate roll stock room, said intermediate roll stock room having a plurality of paper roll sites arranged in plural columns and plural rows, each paper roll site having individual paper roll site coordinates;
- an unpacking and bonding preparation room adjacent to said intermediate roll stock room, said unpacking and bonding preparation room including a first unpacking and bonding preparation station and a second unpacking and bonding preparation station;
- a printing press room adjacent said unpacking and bonding preparation room, said printing room including a first roll stand at a first printing press and a second roll stand at a second printing press;
- roll cart means for moving a paper roll to one of said unpacking and bonding preparation stations and one of said roll stands including a first rail set extending from a first rail set starting location in said intermediate roll stock room to a first rail set ending location beyond said first roll and with respect to said unpacking and bonding preparation room and a second rail set extending from a second rail set starting location in said intermediate roll stock room to a second rail set ending location beyond said second roll stand with respect to said unpacking and bonding preparation room and a roll cart on said first rail set and a roll cart on said second rail set;
- stock room paper conveying means for conveying paper rolls from a loading point of said main stock room to a receiving location of said intermediate roll stock room;
- freely and selectively accessible transport means for freely and selectively moving between said stock room paper conveying means receiving location, each of said paper roll sites in said intermediate roll stock room and said first rail set starting location and said second rail set starting location for engaging a paper roll at said stock room paper roll conveying means receiving location, moving said paper roll above said sites of said intermediate roll stock room to a determined site and depositing the paper roll at said determined sites and engaging the paper roll at said determined site, moving said paper roll above said sites of said intermediate roll stock room to one of said first rail set starting location and said second rail set starting location and depositing the paper roll at said one of said first rail set starting location and said second rail set starting location;
- control means including a data acquisition device located adjacent said stock room paper roll conveying means for receiving data paper roll including weight, paper grade and position coordinates of said determined site of said sites of the intermediate roll stock room for controlling and monitoring movement of the paper roll.
