Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines Doppelbandkalibrators zur Herstellung von Hohlkammerprofilen, welche ebene Außenwände und diese verbindende Stege aufweisen, die durch Extrusion von mindestens einem thermoplastischen Kunststoff mittels mindestens einer formgebenden Düse gebildet werden und sodann gemeinsam als Hohlkammerprofilstränge den Walzenspalt des Doppelbandkalibrators durchlaufen. Die Erfindung betrifft ferner eine geeignete Einrichtung zur Durchführung des Verfahrens.The The invention relates to a method for operating a Doppelbandkalibrators for the production of hollow chamber profiles, which have flat outer walls and these connecting webs, which by extrusion of at least a thermoplastic material by means of at least one shaping Nozzle are formed and then together as hollow chamber profile strands go through the nip of Doppelbandkalibrators. The invention further relates to a suitable device for implementation of the procedure.
Hohlkammerprofile aus Kunststoff werden vielfach in der Fassadentechnik oder z. B. für sparrenlose Lichtbänder in Dach und Wand verwendet. Zu diesem Zweck ist es auch bekannt, die Hohlkammerprofile aus einem schlagzähen, witterungsbeständigen Kunststoff wie Polykarbonat herzustellen.Hollow profiles made of plastic are often in the facade technology or z. B. used for rafterless rooflights in roof and wall. For this purpose it is also known, the hollow chamber profiles from a impact-resistant, weather-resistant plastic how to make polycarbonate.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine geeignete Einrichtung hierzu aufzuzeigen, mit dem bzw. mit der Hohlkammerprofilplatten für insbesondere Steck- oder Schnappsysteme in einfacher und wirtschaftlicher Weise hergestellt werden können.outgoing From this prior art, the invention is based on the object to disclose a method and a suitable device therefor, with or with the hollow chamber profile plates for particular Plug-in or snap-in systems in a simple and economical way can be produced.
Diese Aufgabe wird zum einen dadurch gelöst, dass bei der Extrusion der Hohlkammerprofile an deren seitlichen Stirnwänden in Strangrichtung verlaufende und in ihrer Form zueinander komplementär ausgebildete Seitenstege an- bzw. in diese eingeformt werden.These Task is solved on the one hand, that in the extrusion the hollow chamber profiles at the lateral end walls in Strangrichtung extending and complementary in shape to each other formed side bars on or be molded into this.
Nach Maßgabe der vorliegenden Erfindung ist es dabei zweckmäßig, dass die geformten Seitenstege mittig angeordnet sind und parallel zur Längsrichtung der Hohlkammerprofile an deren Stirnwänden an- bzw. eingeformt werden. Die an den seitlichen Seitenwänden angeformten Seitenstege stehen dabei senkrecht von diesen ab und die eingeformten Seitenstege ragen von den seitlichen Seitenwänden senkrecht ins Innere des jeweiligen Strangs. Die Seitenstege werden dabei vorteilhaft im Querschnitt klöppelartig ausgebildet, damit in der Praxis jede erzeugte Hohlkammerprofilplatte mit benachbarten und entsprechend ausgebildeten Hohlkammerprofilplatten in einfacher und sicherer Art und Weise nach einem Steck- oder Schnappsystem mit einander verbunden werden können.To In accordance with the present invention, it is expedient in that the shaped side webs are arranged centrally and in parallel to the longitudinal direction of the hollow chamber profiles on the end walls be formed or molded. The on the side sidewalls molded side bars stand perpendicularly from these and the molded side bars protrude from the lateral side walls vertically into the interior of the respective strand. The sidewalks will be advantageous in cross-section formed like a clapper, so that in practice every generated hollow profile plate with adjacent and trained hollow chamber profile plates in a simple and safe way to a plug or snap system can be connected with each other.
Je nach Breite des verwendeten Doppelbandkalibrators, können auch zwei oder mehr Hohlkammerprofilstränge diesen durchlaufen, wobei dann abwechselnd je Hohlkammerprofilstrang ein senkrecht abstehender und ein als Ausnehmung ins Innere ragender Seitensteg an die seitlichen Stirnwände an- bzw. in diese eingeformt wird.ever according to the width of Doppelbandkalibrators used, can also pass through two or more hollow profile sections this, then alternately per hollow profile profile strand a vertically projecting and a side bar projecting into the interior as a recess on the lateral side End walls on or is formed in this.
Bei dem erfindungsgemäßen Verfahren wird vorteilhaft ausgehend von einem Extruder plastifizierter Kunststoff über mindestens eine formgebende Mehrschichtendüse dem Walzenspalt des Doppelbandkalibrators in der Form als mindestens einen Hohlkammerprofilstrang zugeführt, wobei im Falle eines Strangs sowohl der senkrecht abstehende als auch der als Ausnehmung ins Innere ragende Seitensteg durch die formgebende Mehrschichtdüse gebildet wird. Dabei ist es zweckmäßig, dass für die Kalibrierung der Seitenstege im Walzenspalt des Doppelbandkalibrators entsprechend ausgebildete leistenartige Formschuhe verwendet werden.at the method according to the invention is advantageous starting from an extruder plasticized plastic over at least one shaping multilayer nozzle the nip the Doppelbandkalibrators in the form of at least one hollow profile profile strand supplied, wherein in the case of a strand both the perpendicular protruding as well as the recess projecting into the interior side bar is formed by the shaping multilayer nozzle. there it is appropriate for calibration the side bars in the nip of Doppelbandkalibrators accordingly trained strip-like form shoes are used.
Um die von den erzeugten Hohlkammerprofilsträngen später abgelängten Hohlkammerprofilplatten mit möglichst glatten Oberflächen zu erhalten, ist es vorteilhaft, die auf etwa Schmelztemperatur erhitzten umlaufenden Endlosbänder des Doppelbandkalibrators mit Kühlzonen auszubilden, die je Durchlauffortschritt der Hohlkammerprofilstränge durch den Walzenspalt in ihrer Intensität unterschiedlich gesteuert werden.Around that of the generated hollow profile sections later cut hollow profile sheets with as possible To obtain smooth surfaces, it is advantageous to the heated to about melting temperature circulating endless belts of Doppelbandkalibrators with cooling zones, the per continuous progress of the hollow chamber profile strands The nip controlled differently in intensity become.
Die zur Durchführung des aufgezeigten Verfahrens vorgesehene Einrichtung umfasst einen üblichen Extruder, mindestens eine formgebende Düse und einen Doppelbandkalibrator, wobei letzterer zwei auf Trommeln umlaufende Endlosbänder besitzt, die einen längsverlaufenden Walzenspalt zur Aufnahme mindestens eines Hohlkammerprofilstranges begrenzen.The intended to carry out the process indicated Device includes a standard extruder, at least a shaping nozzle and a Doppelbandkalibrator, wherein the latter has two endless belts running on drums, a longitudinal nip for receiving at least one Limit hollow section profiles.
Um maßgenaue Seitenstege letztlich an bzw. in den fertigen Hohlkammerprofilplatten zu erhalten, ist es von Vorteil, wenn der Walzenspalt des Doppelbandkalibrators beidseitig durch jeweils einen leistenartigen Formschuh zur Kalibrierung der durch die Mehrschichtendüse gebildeten Seitenstege begrenzt ist. Zusätzlich hierzu, falls relativ schmale Hohlkammerprofilplatten erwünscht sind, kann auch in Querrichtung des Walzenspaltes mittig ein weiterer leistenartiger Formschuh vorgesehen werden, wobei dieser dazu jeweils zu beiden Breitseiten klöppelartig ausgebildete Arme aufweist, mit denen dieser Formschuh in die jeweils entsprechend ausgeformten Ausnehmungen der Hohlkammerprofilstränge formschlüssig eingreift.Around dimensionally accurate side bars ultimately on or in the finished To obtain hollow profile sheets, it is advantageous if the Nip of Doppelbandkalibrators on both sides by one strip-like form shoe for calibration through the multi-layer nozzle formed side bars is limited. In addition to this, if relatively narrow hollow profile plates desired are, can also in the transverse direction of the nip in the middle of another be provided strip-like form shoe, this to each has bobbin-shaped arms on both broad sides, with which this form shoe into each correspondingly shaped recesses the hollow chamber profile strands positively engages.
