Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren und eine Anlage zum Trocknen von Dachziegel-Formlingen in einlagiger Anordnung auf Formlingsträgern.The invention relates to a method and a system for drying roof tile moldings in a single-layer arrangement on molded carriers.
Bei dieser Technik werden bisher einzelne H-Kassetten, welche jeweils nur einen Dachziegel-Formling aufnehmen, verwendet. Dabei ergibt sich ein umständliches und zeitraubendes Handling sowie eine platzraubende, kostspielige und letzlich kaum wirtschaftliche Anlage.Up to now, individual H-cassettes, each of which only hold one roof tile molding, have been used in this technique. This results in cumbersome and time-consuming handling as well as a space-consuming, expensive and ultimately hardly economical system.
Der Erfindung liegt die Aufgabe zugrunde, ein einfacheres und wirtschaftlicheres Verfahren sowie eine dementsprechende Anlage zum einlagigen Trocknen von Dachziegel-Formlingen zu schaffen, welches zwar die von H-Kassetten-Anlagen bekannte Produkt-Qualität ermöglicht, jedoch die Nachteile von H-Kassetten- Anlagen vermeidet.The invention has for its object to provide a simpler and more economical method and a corresponding system for single-layer drying of roof tile moldings, which allows the product quality known from H-cassette systems, but the disadvantages of H-cassette systems avoids.
Erfindungsgemäß wird dies durch ein Verfahren gemäß Patentanspruch 1 sowie eine Anlage gemäß Patentanspruch 6 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention, this is achieved by a method according to claim 1 and a system according to claim 6. Advantageous further developments result from the subclaims.
Mit dem erfindungsgemäßen Verfahren und der erfindungsgemäßen Anlage können auf einfachere und wirtschaftlichere Weise als bei bekannten H-Kassetten-Anlagen für die Falzdachziegel-Trocknung nun grüne Falzdachziegel verzugsarm, d.h. weitestgehend verzugsfrei, getrocknet werden - wie dies bisher nur unter Verwendung von den Rohling formgerecht unterstütrenden H-Kassetten möglich war.With the method according to the invention and the system according to the invention, green folding roof tiles can now be warped with less warpage, in a simpler and more economical manner than with known H-cassette systems for the drying of roof tiles. largely free of distortion, can be dried - as was previously only possible using H cassettes that support the blank in a form-fitting manner.
Eine formgerechte und gute Unterstützung von Falzdachziegeln (vgl. Zeichnung) - deren seitliche Randbereiche bekanntlich im Dachziegelquerschnitt auf unterschiedlichen Ebenen liegen - ist in einfacher Weise durch das Vorsehen von entsprechenden Stützvorsprüngen und/oder Vertiefungen für jeden einzelnen Rohling am bzw. im eine Vielzahl von Rohlingen aufnehmenden Trocknerrahmen gegeben/möglich.A correct and good support for interlocking roof tiles (see drawing) - the lateral edge areas of which are known to lie at different levels in the roof tile cross-section - can be easily achieved by providing corresponding support projections and / or depressions for each individual blank on or in a large number of blanks receiving dryer frame given / possible.
Die Erfindung zeichnet sich durch die gruppenweise und somit besonders rationelle Trocknerwagen-Beladung für das Schnelltrocknen in vertikaler Einzelschicht (oder ggf. auch Doppelschicht) mit jeweils guter, d.h. allseitiger Luftumspülung sowie ebenso rationelle und einfache Trocknerwagen-Entladung aus. Das Besondere ist, daß die grünen Dachziegel einzeln und flach auf einen Trocknerrahmen aufgelegt, nachfolgend mit diesem in eine aus der Vertikalen geneigten Schrägstellung aufgerichtet und in solcher Position auf dem Trocknerwagen abgestellt werden - sowie in umgekehrter Weise entladbar sind.The invention is characterized by the group-wise and thus particularly efficient loading of the dryer car for rapid drying in a vertical single layer (or possibly also a double layer) with good, i.e. all-round air circulation as well as efficient and simple dryer car unloading. The special thing is that the green roof tiles are placed individually and flat on a dryer frame, subsequently erected with it into an inclined position inclined from the vertical and placed in such a position on the dryer cart - and can be unloaded in the reverse manner.
Die Schrägstellung der beladenen Trocknerrahmen ermöglicht eine intensive oben- und untenseitige Beströmung der zu trocknenden Dachziegel-Formlinge. Eine automatische beidseitige Formlingsanblasung ergibt sich sowohl durch den Wagentransport als auch durch eine nach dem Gegenstromprinzip durch einen Tunneltrockner strömende Trocknungsluft. Der optimale Neigungswinkel zwischen Dachziegel-Rückseite und der Transportebene/Horizontalen hängt vom Dachziegelmaterial ab und wird so gewählt, daß einerseits eine gute Stabilität innerhalb des grünen Falzziegels ohne Durchbiegungs- oder Verformungsgefahr und andererseits ein leichtes Gleiten beim Trocknungsschwund gewährleistet ist - vorteilhafterweise beträgt dieser Winkel etwa 50 - 80°.The inclined position of the loaded dryer frame enables intensive top and bottom flow of the roof tile moldings to be dried. Automatic blown molding on both sides results from both the carriage transport and the drying air flowing through a tunnel dryer according to the countercurrent principle. The optimum angle of inclination between the back of the roof tile and the transport plane / horizontal depends on the roof tile material and is selected so that on the one hand good stability within the green interlocking tile without risk of bending or deformation and on the other hand easy sliding during drying shrinkage is guaranteed - this angle is advantageously approximately 50 - 80 °.
Aufgrund der bevorzugten Überlappung zwischen in Trocknerwagen-Transportrichtung beabstandet hintereinanderliegenden Handhabungseinheiten beladene Trocknerrahmen" ergibt sich eine ökonomische Raumausnutzung auf jedem Trocknerwagen - der Grad solcher Überlappung hängt von dem Formlingsmaß in der Höhenrichtung des Trockners, dem Neigungswinkel der Schrägstellung zur Vertikalen sowie dem für das sichere Be- und Entladen erforderlichen Abstandsmaß zwischen hintereinanderliegenden Reihen ab.Because of the preferred overlap between handling units which are spaced one behind the other in the dryer carriage transport direction loaded dryer frames "results in an economical use of space on each dryer car - the degree of such overlap depends on the shape dimension in the height direction of the dryer, the angle of inclination of the inclined position to the vertical as well as the distance dimension required for safe loading and unloading between rows one behind the other.
