Les lignes de processus continues nécessitent d’acquérir les données en fonction de leur longueur pour qualifier les produits. Le système d’enregistrement des données qualité ibaQDR acquière les données selon des critères temporels en différents emplacements de mesure et assigne les valeurs de mesure de manière précise en fonction de la longueur du produit.
- Système d’enregistrement des données qualité basé sur l’architecture ibaPDA
- Description des processus technologiques des lignes de traitement en bande
- Normalisation de la longueur en fonction du produit final (bobine de sortie) et synchronisation de toutes les données de mesure
- Prise en compte de l’étirement de la bande dans le processus et de toutes les découpes
- Résolution standard de la longueur : 1 m (entièrement ajustable, unité comprise)
The quality data recording system ibaQDR is smoothly integrated in ibaPDA as an add-on. The user has the same look-and-feel like in ibaPDA. This offers a transparent quality data acquisition and an efficient data management.
A product (coil)-related analysis of quality data only makes sense, if the relevant measured values can be mapped exactly to the product. In case of long products, a length-based mapping of the data over the product is usually required, e. g. feet-wise or meter-wise.
ibaQDR does this mapping based on the previous time-based recorded data in combination with accurate data of the material tracking. The successively recorded (time-based) data are mapped exactly to the product at the point where they have been measured.
The system has been optimized for rolling mills, processing lines and inspection plants within the metal industry but it can also be used for reversing rolling processes in hot rolling mills or other processes.
Quality relevant data are:
Product dimensions (width, thickness,...)
Cross profiles (strip coating, thickness cross-profile,...)
Production parameters (rolling forces, tensions, ...)
Reference values and consumption figures etc.
The production line is divided into several sections (measuring locations), where the quality relevant data are acquired. At first, the measuring data are recorded separately based on the measuring locations, together with the material ID and the position (length) of the strip in relation to the measuring location.
This creates as many measurement files as measurement locations. When the product (coil) is finished (e.g. defined by shear cut) the measurement data are extracted from the temporary single files based on the material ID and the length positions and will be written into a new file – the QDR data file. All measurement values belonging to the recently produced strip are stored scaled to the final product length. Production- related material elongations are taken into account.
ibaQDR is based completely on ibaPDA and the iba hardware. Therefore the whole iba connectivity is available. The signals to be measured are configured in the same I/O Manager as in ibaPDA.
The status of the recording is monitored continuously in a special window showing the current material-ID and length at the measuring location, no matter whether a recording is running or not.
Besides the name of a measuring location further information is entered in the configuration dialog, such as control signals from material tracking, like material- ID and actual length position.
An appropriate number of measuring locations can be defined throughout the line. Another arbitrary number of measuring signals can be assigned to each measuring location.
The data files which are generated by ibaQDR can be analyzed and displayed with ibaAnalyzer. Demanding reports can be generated with the powerful report generator.
Using the software ibaAnalyzer-DB the recorded data can be provided to higher level systems, such as MES (Manufacturing Execution System), DataWarehouse or individual applications in a plain and transparent database structure.
This software is one of many useful add-ons of ibaPDA
Élément central du système iba, ibaPDA s’impose depuis des années comme l’un des systèmes de saisie de données les plus polyvalents au service de la maintenance et de la production. Parmi ses fonctions les plus convaincantes, on retrouve notamment son architecture client-serveur, l’enregistrement flexible ou la facilité de configuration grâce à Auto-Detect.
Please note: As ibaQDR works in close relation to the segment mapping of the automation, a detailed knowledge of the functioning of the automation is required for the configuration.
Therefore we recommend the integration of the system through a qualified supplier or together with support services (consulting, training, support).
