Abstract

In the traditional plywood manufacturing process, the lay-up stage absorbs approximately 24% of the total manufacturing costs. It usually requires a large amount of manpower and produces a significant amount of waste material. Therefore, the authors have developed an innovative system based on a new idea that reduces these values drastically. The solution is characterized by intensive use of flexible automation, and this breakthrough lay-up system technology is specifically discussed in relation to plywood manufacture. Since the new system was tested, it has been adopted and used by the European leader in poplar plywood manufacturing.

Interesting results include productivity increases of up to 20%, a decrease in lay-up costs of approximately 19% and a consumption of area reduced about 42%. Moreover, by reducing manpower requirements, the new system generates a significant reduction in the number of problems relating to product quality and operator safety, which is certainly not a trivial question in the traditional lay-up system.

Zusammenfassung

Bei der konventionellen Sperrholzherstellung gehen 24% der gesamten Herstellungskosten zu Lasten der Legephase. Hierzu wird in der Regel ein hoher Personalaufwand benötigt und eine erhebliche Menge an Abfall wird produziert. Aus diesem Grunde wurde von den Autoren ein innovatives Verfahren entwickelt, das auf einer neuen Idee basiert, mit der diese Faktoren erheblich reduziert werden. Die Lösung besteht im Einsatz flexibler Automatisierung. Dieses bahnbrechende Legeverfahren wird hier am Beispiel der Sperrholzherstellung beschrieben. Inzwischen wurde dieses neue Verfahren vom führenden europäischen Hersteller von Pappelsperrholz übernommen und eingesetzt.

Zu den interessanten Ergebnissen zählen Produktivitätszunahmen von bis zu 20%, ein Rückgang der Legekosten von ca. 19% und eine Reduktion der benötigten Fläche von ungefähr 42%. Außerdem reduziert das neue Verfahren aufgrund des geringeren Personalbedarfs die bei dem traditionellen Verfahren bekannten Probleme hinsichtlich der Produktqualität und der Betriebssicherheit.
