Abstract
A method for defining the operation of a plant for producing, conveying and packaging articles. The articles include rolls, such as rolls of paper material and the like. The plant includes the following operative sections: at least an apparatus for forming articles positioned upstream, at least a machine for packaging the articles in respective packs positioned downstream, and an apparatus for conveying the articles which is able to transfer the articles between the forming apparatus and the packaging apparatus. The method and the plant provide that, through a central control unit of the plant, starting from predefined setting data, operating parameters of the sections of the plant are determined.
Claims18
A plant for producing, conveying and packaging articles, comprising at least an apparatus for forming articles positioned upstream, which has at least a local control unit comprising processor means operating under the control of a predefined program which governs the operation of said forming machine in response to corresponding setting data which are provided to said processor means of the forming machine;
- at least a packaging machine positioned downstream, which is able to package said articles and has at least a respective local control unit comprising processor means operating under the control of a predefined program that governs the operation of said packaging machine in response to corresponding setting data which are provided to said processor means of the packaging machine;
- and an apparatus for conveying the rolls which is able to transfer said rolls between said forming machine and said packaging machine and which presents at least a respective local control unit comprising processor means operating under the control of a predefined program that governs the operation of said conveying apparatus in response to set data input into said processor means of the conveying apparatus, wherein a central control unit is provided which has a program for determining operating parameters of the plant, which, starting from predefined setting data provided to said central unit and relating to a desired operation of the plant, provides, for the respective microprocessor means of the local control units, corresponding data for setting the operation of said upstream forming machine, of said downstream packaging machine and of said conveying apparatus.
A plant for producing and packaging articles, said plant comprising the following operative sections:
- and apparatus for forming articles having a first and a second cutting sections which are able to cut the articles in the form of rolls from respective elongated coils, said cutting units sending the articles to respective machine for packaging the articles downstream therefrom, said cutting sections being fed with elongated coils coming from a single coil magazine fed by a single re-coiling section;
- wherein it comprises a control unit such that, when an event that determines the operation of one of the cutting sections to be stopped is detected, it verifies the operating state of the other cutting section of the plant, and determines a procedure for rearranging the operation of the plant;
- and wherein said rearranging procedure provides, if the other section of the plant is able to increase its operating rate, for increasing the operating rate of the second cutting section in such a way as to absorb at least partially the load of coils that are no longer processed by the cutting section under conditions of stopped operation.
