The Rieter “SPIDERweb” Mill Information System (Mill Monitoring System)

Index

 SPIDERweb is a user-oriented data system based on Windows. Its modular design permits the interconnection of any number of machines, and can be extended to include additional machines at any time. It permits control and monitoring of the entire mill from bale lay-out to the winding machines.

It enables production data, e.g. weight per time unit, efficiency, stop events, down-times, etc. and quality data, e.g. CV values, spectrograms, Classimat data, etc., from every machine to be logged and analyzed according to the requirements of the mill. A very important feature of this system is the inclusion of an alarm system. The moment any controlled item at any point within the mill crosses a preset limit specified by the mill, this is indicated immediately, and the fault can be eliminated at once.

SPIDERweb is a very modern and important management tool. It relieves management staff of time-consuming routine work, and allows it to concentrate fully on exceptional events, one of the requirements of competent management.

SPIDERweb provides responsible personnel with all necessary data to run the mill without major problems. The initial data required are available from Rieter, but can also be elaborated by the mill itself.

A further advantage of these systems is the potential for constant improvement of quality and productivity due to the following effect: when the alarm record indicates a deficient production unit, the reason for this deficiency can be eliminated, thus enabling the alarm limit to be lowered. The resulting new alarm schedule enables improvements to be made at the next deficient production unit, and so on. Improvement becomes increasingly difficult with each improvement step, of course, and will end when the effort required is greater than the result achieved.
