Abstract
A control device controls a processing installation for the production of collections of printed products, wherein the processing installation includes installation sections which combine input streams of part products into output streams of collections of these part products. Control units are assigned to the installation sections and which, on the basis of a predefined product requirement (Pa2, Pa3, Pa4, Pa21, Pa31, Pa41), activate the assigned installation section for the production of a respective output stream. In each case a control unit is set up to obtain product requirements from the master control or from a different control unit, and to produce product requirements for the control unit of an installation section arranged upstream.
Claims14
A control device for a processing installation for the production of collections of printed products, wherein the processing installation includes at least two installation sections and each of the installation sections is set up to produce an output stream of collections of part products as output products, from several input streams of these part products as input products, and wherein an output stream of at least one first installation section is an input stream of a second installation section arranged downstream of the first installation section, wherein the control device comprises:
- several programmable control units, wherein:
- each control unit is assigned to an associated one of said first and second installation sections and controls and monitors said associated installation section, and
- each control unit, on the basis of a predefined production definition of output products, hereinafter called product requirement, and of a predefined product definition of input products, called product specification, is configured to activate the associated installation section such that the output stream of the associated installation section consists of collections of the part products and corresponds to the product requirement,
- wherein first and second control units are assigned to the first and second installation sections, respectively,
- wherein the second control unit is set up to receive product requirements from a master control or from another control unit,
- wherein the second control unit is set up to produce further product requirements for the first control unit, and
- wherein the first control unit is set up to receive these further product requirements from the second control unit.
A method for controlling a processing installation for producing collections of printed products, wherein the processing installation includes at least two installation sections, and each of the installation sections is set up to produce an output stream of collections of part products, as output products, from several input streams of the part products as input products, and wherein an output stream of at least one first installation section is an input stream of a second installation section arranged downstream of the first one, comprising the steps of:
- providing a control device that comprises several programmable control units, wherein:
- each control unit is assigned to an associated one of the installation sections and controls and monitors the associated installation section,
- each control unit, on the basis of a predefined production definition of output products, hereinafter called product requirement, and of a predefined product definition of input products, called product specification, is configured to activate the associated installation section such that the output stream of the associated installation section corresponds to the product requirement,
- wherein a product definition in each case comprises a specification of a predefined number of individual printed products of a same kind or collections of the same kind, and/or a specification of individual collections, and
- assigning a first and a second control unit to the first and the second installation section respectively,
- the second control unit receives product requirements from a master control or from another control unit and controls the second installation section for the production of part products according to these product requirements,
- the second control unit produces further product requirements for the first control unit, and
- the first control unit receives these further product requirements from the second control unit and controls the first installation section for the production of part products according to the further product requirements.
