Abstract
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Flaschen oder dergleichen Behältern durch Blasformen unter Verwendung von Vorformlingen aus thermoplastischem Kunststoff, beispielsweise aus PET, wobei die Vorformlinge vor dem Blasformen durch Energieeintrag vorerhitzt werden.The invention relates to a method for producing bottles or similar containers by blow molding using preforms made of thermoplastic material, for example made of PET, wherein the preforms are pre-heated prior to blow molding by energy input.
Description
Die Erfindung bezieht sich auf ein Verfahren gemäß Oberbegriff Patentanspruch 1 sowie auf eine Anlage gemäß Oberbegriff Patentanspruch 12.The The invention relates to a method according to the preamble of the patent claim 1 and on a system according to the preamble Claim 12.
Bekannt sind u. a. Verfahren zum Herstellen von Flaschen oder Behältern unter Verwendung von Vorformlingen (Preforms) aus thermoplastischen Kunststoff als Ausgangsmaterial, wobei die Vorformlinge zunächst auf einer Heizstrecke aufgeheizt bzw. erhitzt und anschließend in einer Blasmaschine durch Blasen zu dem jeweiligen Behälter geformt werden. Die Vorformlinge sind in der dem Fachmann bekannten Weise als an einem Ende geschlossene und am anderen Ende mit einem überstehenden Flansch versehene Röhrchen ausgebildet.Known are u. a. Process for producing bottles or containers under Use of preforms made of thermoplastic material as starting material, wherein the preforms initially on a heating line heated or heated and then in a blow molding machine Bubbles to the respective container be formed. The preforms are known in the art As closed at one end and at the other end with a protruding flange provided tubes educated.
Das Aufheizen der Vorformlinge erfolgt in der Heizstrecke durch Energieeintrag, und zwar bei bekannten Heizstrecken oder Anlagen durch Aufheizen mittels Infrarot-Strahler. Nachteilig hierbei ist u. a., dass relativ lange Aufheiz- oder Behandlungszeiten erforderlich sind, d. h. Aufheiz- oder Behandlungszeiten in der Regel in der Größenordnung zwischen 10 und 12 Sekunden. Speziell bei hohen Leistungen (Anzahl der hergestellten Behälter je Zeiteinheit) erfordert dies eine Heizstrecke mit entsprechend großer Länge, in der während des Fertigungsprozesses eine Vielzahl von Vorformlingen aufgenommen sind. Eine kurze und kompakte Bauform ist daher nicht oder nur in aufwendiger Weise möglich. Da weiterhin einmal erhitzte Vorformlinge sofort weiterverarbeitet werden müssen und es auch nicht möglich ist, bereits einmal erhitzte Vorformlinge nach dem Abkühlen nochmals zu erhitzen und für das Blasformen zu verwenden, ist es bei Störungen in einem auf die Heizstrecke folgenden Teil der Anlage, beispielsweise bei Störungen in der Blasformmaschine notwendig, nicht nur die Zufuhr von Vorformlingen an die Heizstrecke zu sperren, sondern die Heizstrecke auch leer zu fahren und dabei die erhitzten Vorformlinge auszuschleusen und zu verwerfen. Bei der relativ großen Länge der bekannten Heizstrecken ist hiervon jeweils eine große Anzahl von Vorformlingen betroffen.The Heating of the preforms takes place in the heating section by energy input, namely in known heating sections or systems by heating means Infrared emitters. The disadvantage here is u. a. that relatively long Heating or treatment times are required, d. H. heating or treatment times usually in the order of 10 to 12 seconds. Especially at high power levels (number of produced container per unit of time) this requires a heating section with accordingly greater Length, in the while recorded a variety of preforms of the manufacturing process are. A short and compact design is therefore not or only in consuming way possible. Because once heated preforms are processed immediately have to and it is not possible is once again heated preforms after cooling again to heat up and for to use the blow molding, it is in case of disturbances in one on the heating line following part of the system, for example in case of malfunctions in the blow molding machine necessary, not only the supply of preforms to the heating section too lock, but also to drive the heating section empty and thereby the remove heated preforms and discard. In the relatively large length of Known heating sections thereof is in each case a large number affected by preforms.
Aufgabe der Erfindung ist es, ein Verfahren aufzuzeigen, mit dem die vorgenannten Nachteile vermieden werden. Zur Lösung dieser Aufgabe ist ein Verfahren entsprechend dem Patentanspruch 1 ausgebildet. Eine Anlage zum Herstellen von Packmitteln ist Gegenstand des Patentanspruches 12.task The invention is to provide a method by which the aforementioned Disadvantages are avoided. To solve this problem is a method formed according to claim 1. A plant for manufacturing of packaging is the subject of claim 12.
Bei der Erfindung erfolgt das Erhitzen des für die Herstellung der Packmittel verwendeten Ausgangsmaterials, beispielsweise der Vorformlinge, durch Beaufschlagung des Ausgangsmaterials mit wenigstens einem Laserstrahl bzw. durch Beaufschlagung mit Laserstrahlenergie.at the invention, the heating is carried out for the production of the packaging used starting material, for example, the preforms, by Loading of the starting material with at least one laser beam or by exposure to laser beam energy.
Insbesondere bei der Herstellung von Flaschen oder dergleichen Behälter kann die Behandlungsdauer beim Erhitzen der Vorformlinge gegenüber den bisher verwendeten Verfahrensweisen wesentlich reduziert werden. Hierdurch ist es dann u. a. auch möglich, bei vorgegebener Leistung einer Anlage zum Herstellen von Behältern durch Blasformen (Anzahl der hergestellten Behälter je Zeiteinheit) die Länge der Heizstrecke und damit die Anzahl der im Falle einer Störung auszuschleusenden und zu verwerfenden Vorformlinge klein zu halten. Weiterhin ist durch die verkürzte Behandlungsdauer ein schnelles Anfahren einer Anlage, insbesondere auch nach Behebung einer Störung möglich.Especially in the manufacture of bottles or the like can container the treatment time when heating the preforms against the previously used procedures are significantly reduced. This makes it u. a. also possible, for a given power a plant for producing containers by blow molding (number the manufactured container per time unit) the length the heating distance and thus the number of auszuschleusenden in case of failure and to be discarded preforms to keep small. Furthermore, by the shortened Treatment time a quick startup of a plant, in particular even after a fault has been rectified possible.
Das erfindungsgemäße Verfahren bietet ferner die Möglichkeit, durch entsprechende Ansteuerung des wenigstens einen Laserstrahls und/oder durch entsprechende Relativbewegung zwischen dem wenigstens einen Laserstrahl und dem jeweiligen Vorformling diesen partiell unterschiedlich zu erhitzen, so dass sich ein Erhitzungs- oder Behandlungsmuster ergibt, welches stärker erhitzte Bereiche und nicht oder weniger stark erhitzte Bereiche aufweist. Hierdurch können beim anschließenden Streck- oder Blasformen Wandstrukturen für die Behälter gebildet werden, die neben dünnwandigen Wandbereichen auch verstärkende Wandbereiche größerer Wanddicke aufweisen. Hierdurch können z. B. dünnwandige Behälter oder Flaschen hergestellt werden, die an Griffbereichen, beispielsweise am Flaschenrumpf oder -bauch verstärkt ausgebildet sind, beispielsweise durch steg- und/oder gitterartige Strukturen usw.The inventive method also offers the possibility by appropriate control of the at least one laser beam and / or by corresponding relative movement between the at least a laser beam and the respective preform this partial to heat differently, so that a heating or treatment pattern which gives stronger heated areas and non or less heated areas having. This allows during the subsequent stretching or blow molding wall structures for the containers be formed, in addition to thin-walled wall areas also reinforcing Wall areas of greater wall thickness exhibit. This allows z. B. thin-walled container or bottles are made to handle areas, for example formed reinforced on the bottle body or belly, for example through web and / or lattice-like structures, etc.
