Embodiment Construction

[0036] figure 1 A simplified diagram of an apparatus 1 for manufacturing a continuously running paper web 2 is shown. The plant 1 comprises the following plant components: material preparation 6 , paper machine 7 , rewinder / calender 8 , roll cutter 9 and cross cutter 10 . The sum of these systems includes energy distribution components 3 , automation technology components 4 and drive technology components 5 . Overall, the device 1 thus forms a complex system of different cooperating computing devices. Due to this complex interaction of different equipment components and devices, it is difficult to find out the chain of action between different equipment components, it is difficult for the equipment operator to determine faults and functional limitations, and it is difficult to evaluate the technical state of the equipment.

[0037] figure 2 A device 20 according to the invention is shown for determining the cause of faults and performance limitations in a device 15 . The ...

Abstract

The invention relates to a method and a device for determining the causes of malfunctions and performance limits in installations. It is difficult to determine the causes of disturbances and / or performance-limiting factors in complex installations (15). The inventive method allows malfunctions in an installation (15) to be eliminated and / or the performance thereof to be increased in a lasting manner and with relatively little effort. Said method comprises the following steps: data (51a-i) is provided on causes of malfunctions and performance limits in a plurality of installations (40a-c); a questionnaire 26) regarding said causes is created from said data; replies (27) relating to the questions of the questionnaire (26) are solicited from employees (29) working in the installation (15) that is to be diagnosed; and the causes of malfunctions and performance limits of the installation (15) that is to be diagnosed are determined by evaluating the replies (27) supplied by the employees (29) regarding the questions of the questionnaire (26).

Description

technical field [0001] The present invention relates to methods and apparatus for determining the cause of malfunctions and efficiency limitations in equipment. Background technique [0002] Technical equipment represents an increasingly complex system with numerous interacting technical devices. Plants for the production of continuously running goods such as paper, textiles, plastics or metal foils are characterized by a particularly complex combination of devices for distributing energy, drive systems and automation systems. [0003] At the same time, many plant operators are increasingly focusing on their core process, that is, the process of the method technology, and less attention is paid to the individual technical components (such as drive and automation) required by the method technology process. parts). [0004] For this reason and due to the ever-increasing complexity of equipment, many plant operators find it difficult to determine in their equipment the cause ...
