Description

Die Erfindung betrifft eine Anlage zum Herstellen und Be- bzw. Verarbeiten von Behältern nach dem Oberbegriff des Anspruchs 1.The The invention relates to a plant for manufacturing and processing of containers according to the preamble of claim 1.

Solche bekannte Anlagen beziehen sich hauptsächlich auf die Verbindung von Behälterherstellungsmaschinen, wie z.B. Blasmaschinen, mit weiteren Behandlungsmaschinen wie z.B. Füllmaschinen, wobei die Einzelmaschinen in Reihe zu einem Block verschaltet werden.Such known plants relate mainly to the compound of Container manufacturing machines, such as. Blow molding machines, with other treatment machines such. filling machines, wherein the individual machines are connected in series to form a block.

So zeigt z.B. die DE 199 28 325 A1 eine Abfüllvorrichtung für Flaschen, bei der eine Streckblasmaschine für PET-Behälter direkt mit einem Rinser und im Anschluss mit einem Füller zu einem Block verknüpft sind, wobei die einzelnen Maschinen synchron zueinander angetrieben werden.So shows eg the DE 199 28 325 A1 a bottle filling machine in which a PET bottle stretch blow molding machine is linked directly to a rinser and then to a block with a filler, the individual machines being driven synchronously with each other.

Die DE 198 24 846 A1 zeigt eine Flaschenfüllanlage, bei der die Blasmaschine und der Füller in Reihe zu einem Block verschaltet sind. Zusätzlich ist hier an das Transferelement zwischen Blasmaschine und Füllmaschine ein Puffersystem gekoppelt, das die Störung einer der beiden Maschinen im Block für eine gewisse Zeit ausgleichen kann.The DE 198 24 846 A1 shows a bottling plant, in which the blowing machine and the filler are connected in series to form a block. In addition, a buffer system is here coupled to the transfer element between the blowing machine and the filling machine, which can compensate for the disturbance of one of the two machines in the block for a certain time.

Ein Nachteil bei diesen in Serie zu einem Block verknüpften Maschinen ist unter anderem die mangelnde Flexibilität in Bezugnahme auf den herzustellenden Gegenstand. Sollen z.B. in Behältern gleicher Form verschiedene Produkte abgefüllt werden, so muss bei der Verwendung einer der soeben beschriebenen Anlagen die komplette Abfüllvorrichtung inklusive Blasmaschine stillgesetzt werden, bis die Füllmaschine auf das neue Produkt umgestellt ist. Dies ist eine Stillstandszeit, die die Effektivität der Gesamtanlage reduziert.One Disadvantage of these machines linked in series to a block Among other things, the lack of flexibility in relation to the manufactured Object. If, for example, in containers same form different products are bottled, so must at the Using one of the plants just described the complete Filling device included Blowing machine be shut down until the filling machine to the new product converted. This is a downtime that affects the effectiveness of the overall system reduced.

Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Anlage zum Herstellen von Behältern zu schaffen, die durch ihre Anordnung eine höchstmögliche Flexibilität bei der Verarbeitung von verschiedenen Produkten bietet.It is therefore an object of the present invention, a system for Making containers too create, by their arrangement the highest possible flexibility in the Processing of different products offers.

Die Aufgabe wird erfindungsgemäß durch das Kennzeichen des Anspruchs 1 gelöst.The The object is achieved by the Characteristics of claim 1 solved.

Die erfindungsgemäße Anlage zum Herstellen von Behältern umfasst eine Heizeinrichtung, die das Material, aus dem die Behälter hergestellt werden, erwärmt. Die Heizeinrichtung kann z.B. ein Heizofen sein, der Glas- oder Kunststoffpreforms erwärmt, bevor sie in der Behälterproduktionsvorrichtung zu einem Behälter verformt werden. Die Heizeinrichtung kann auch ein in die Behälterproduktionsvorrichtung eingebettetes Erwärmungssystem wie zum Beispiel vor einem Extruder sein, das ein Behältermaterial auf Verarbeitungstemperatur bringt. Bei der Behälterproduktionsvorrichtung kann es sich z.B. um eine Tiefziehvorrichtung, um eine Spritzgießvorrichtung oder um eine Blas- bzw. Streckblasvorrichtung handeln. Gemäß einer bevorzugten Ausführungsform der Erfindung wird die Behälterproduktionsvorrichtung durch eine Blasmaschine für Glas- bzw. Kunststoffflaschen, besonders bevorzugt durch eine Streckblasmaschine insbesondere für PET-Flaschen gebildet.The inventive plant for producing containers includes a heater, which is the material from which the containers are made be warmed up. The heater may e.g. be a stove, glass or Kunststoffpreforms warmed, before entering the container production facility to a container be deformed. The heater may also be inserted into the container production device embedded heating system such as in front of an extruder that is a container material brings to processing temperature. In the container production device it can be e.g. to a thermoforming device to an injection molding device or act a blow or stretch blower. According to one preferred embodiment The invention relates to the container production apparatus through a blowing machine for Glass or plastic bottles, more preferably by a stretch blow molding machine especially for Made of PET bottles.

Das Transferelement hat die Aufgabe, die von der Behälterproduktionsvorrichtung produzierten Behälter abzuführen und auf Steuersignale so zu reagieren, dass nachfolgend parallel angeordnete Behandlungsmaschinen wahlweise beschickt werden können. Die Ausgestaltung des Transferelements kann beliebig sein. Es ist zum Beispiel möglich, dass das Transferelement ein Rollenförderer, ein Bandförderer, ein Kettenförderer mit Greifklammern oder ein Transferstern ist. Nach einer bevorzugten Weiterbildung wird das Transferelement von einer mit Hals- und/oder Rumpfgreifern ausgestatteten Transportkette gebildet, die um zwei vertikale Achsen umläuft.The Transfer element has the task of the container production device dissipate produced container and to respond to control signals so that subsequently arranged in parallel Treatment machines can be optionally loaded. The Configuration of the transfer element can be arbitrary. It is for Example possible, the transfer element is a roller conveyor, a belt conveyor, a chain conveyor with gripping clamps or a transfer star is. After a preferred Continuing the transfer element is one with neck and / or Hull gripper equipped transport chain formed by two vertical axes rotates.

Eine wahlweise Beschickung der nachfolgenden Behandlungsmaschinen kann bedeuten, dass nur eine Behandlungsmaschine oder dass beide Behandlungsmaschinen in bestimmten Verhältnissen beschickt werden. Eine Beschickung von 0% zu 100% ist genauso möglich wie eine Beschickung von 50% zu 50% oder von 100% zu 0%. Eine zufällige Beschickung der Behandlungsmaschinen ist selbstverständlich auch denkbar.A optionally charging the subsequent treatment machines mean that only one treatment machine or both treatment machines in certain circumstances be charged. A charge of 0% to 100% is just as possible as a feed of 50% to 50% or from 100% to 0%. A random load of the treatment machines is of course also conceivable.

Gemäß einer bevorzugten Weiterbildung der Erfindung sind der Behälterproduktionsvorrichtung genau zwei Behandlungsmaschinen nachgeschaltet, die vorzugsweise durch zwei Füllmaschinen gebildet werden. Diese Anordnung hat den Vorteil, dass in Behälter gleicher Form verschiedene Produkte abgepackt werden können, ohne eine Stillstandszeit der Anlage bei einem Produktwechsel durch die Reinigung und Umstellung des Füllers auf das neue Produkt in Kauf nehmen zu müssen. Es ist z.B. auch eine Anlagenkonfiguration denkbar, bei der eine Hochleistungsstreckblasmaschine für Kunststoffbehälter mit zwei mit der halben Leistung der Streckblasmaschine ausgestatteten Füllmaschinen verbunden ist, von denen immer abwechselnd die Eine und die Andere beschickt wird.According to one preferred embodiment of the invention, the container production device are accurate downstream of two treatment machines, preferably by two filling machines be formed. This arrangement has the advantage that the same container Different products can be packaged without a downtime the system at a product change by the cleaning and conversion of the filler to have to accept the new product. It is e.g. also a plant configuration conceivable in which a Hochleistungsstreckblasmaschine for plastic containers with two filling machines equipped with half the capacity of the stretch blow molding machine Of which always alternately one and the other is charged.

Diese Konfiguration hat weiterhin den Vorteil, dass Störungen bei einer der beiden nachgeschalteten Behandlungsmaschinen zumindest insoweit kompensiert werden können, dass die Behälterproduktionsmaschine nicht stillgesetzt sondern nur in ihrer Leistung reduziert werden muss bis der Fehler in einer der beiden Behandlungsmaschinen behoben worden ist.This configuration also has the advantage that disturbances in one of the two downstream treatment machines can be compensated, at least to the extent that the container production machine is not stopped, but only in ith performance must be reduced until the error has been corrected in one of the two treatment machines.

Gemäß einer anderen bevorzugten Weiterbildung sind der Behälterproduktionsvorrichtung zwei Etikettiermaschinen parallel nachgeordnet. Diese Anordnung hat den Vorteil, dass gleiche Behälter mit verschiedenen Etiketten versehen werden können, ohne dass ein Etikettenwechsel an der Etikettiermaschine vorgenommen werden muss.According to one Another preferred development is the container production device downstream of two labeling machines in parallel. This arrangement has the advantage of having identical containers with different labels can be provided without that a label change made on the labeling machine must become.

Nach einer weiteren Weiterbildung der Erfindung sind der Behälterproduktionsvorrichtung n beliebige Behandlungsmaschinen nachgeschaltet, die jeweils mehr als die 1/n -fache Leistung der Produktionsvorrichtung besitzen. Dadurch kann bei einem Ausfall einer Behandlungsmaschine die Leistung der Verbleibenden problemlos heraufgesetzt werden, ohne die Leistung der Behälterproduktionsvorrichtung herabzusetzen zu müssen.To A further development of the invention is the container production device n any treatment machines downstream, each more than the 1 / n times performance of the production device. As a result, in case of failure of a treatment machine, the performance the remainder can be easily upgraded without sacrificing performance the container production device to have to minimize.

Eine weitere Vorteilhafte Konfiguration besteht darin, dass die Behälterproduktionsmaschine mehrere verschiedene Behältersorten produziert, von denen jeweils eine Sorte an eine Behandlungsmaschine und die andere(n) Sorte(n) an die andere(n) Behandlungsmaschine(n) weitergegeben wird.A Another advantageous configuration is that the container production machine has several different container types each of which produces a variety to a treatment machine and the other variety (s) to the other treatment machine (s) is passed on.

Nach einer bevorzugten Weiterbildung der Erfindung ist das Transferelement zwischen der Behälterproduktionsvorrichtung und den Behandlungsmaschinen als Puffertransferelement ausgebildet. Dies hat zum einen den Vorteil, dass Störungen an den Einzelmaschinen der Anlage ausgeglichen bzw. kompensiert werden können und zum anderen hat die Verwendung eines Asynchronpuffers den Vorteil, dass die Maschinen in der Anlage nicht synchron zueinander laufen müssen, da eine Asynchronität bezüglich der Laufgeschwindigkeit der Maschinen durch den Puffer ausgeglichen wird.To A preferred embodiment of the invention is the transfer element between the container production device and the treatment machines designed as a buffer transfer element. This on the one hand has the advantage that disturbances on the individual machines the system can be compensated or compensated and On the other hand, the use of an asynchronous buffer has the advantage that the machines in the system do not have to run synchronously with each other because an asynchrony in terms of the running speed of the machines is compensated by the buffer becomes.

Im Nachfolgenden wird ein Ausführungsbeispiel der erfindungsgemäßen Anlage näher beschrieben. Es zeigt:in the The following will be an embodiment the plant of the invention described in more detail. It shows:

1 zeigt als eine Behälterproduktionsvorrichtung 6 eine Rotationsblasmaschine 6 und zwei mittels des Transferelements 10 mit der Rotationsblasmaschine 6 gekoppelte Füllmaschinen 7 und 8. Die Anlage 1 weist zu Beginn einen Preformspeicher 21 auf, in dem die Preforms (Vorformlinge) vor ihrer Verarbeitung gespeichert werden. Aus diesem Preformspeicher 21 werden die Vorformlinge über einen Preformausrichter 22, der die Aufgabe hat, die Preforms in eine einheitlich sortierte Form zu bringen, und die Preformzuführung 23 der Heizeinrichtung 5 zugeführt. Die Übergabe von der Preformzuführung 23 an die Heizeinrichtung 5 erfolgt über einen Transferstern 24, der die Vorformlinge im Bereich ihrer Mündung unterstützt. 1 shows as a container production device 6 a rotary blowing machine 6 and two by means of the transfer element 10 with the rotary blowing machine 6 coupled filling machines 7 and 8th , The attachment 1 has a Preformspeicher at the beginning 21 in which the preforms are stored prior to their processing. From this Preformspeicher 21 The preforms are passed over a preform aligner 22 , which has the task to bring the preforms in a uniformly sorted form, and the preform feed 23 the heater 5 fed. The transfer from the preform feeder 23 to the heater 5 takes place via a transfer star 24 supporting the preforms in the area of their mouth.

Die Heizeinrichtung 5 wird durch einen im Wesentlichen rechteckigen Heizofen gebildet, wobei die Vorformlinge auf zwei parallelen gegenläufigen Bahnen durch den Ofen geführt werden und die Umlenkung von der einen in die andere Bahn am oberen Ende des Heizofens 5 erfolgt. Die Vorformlinge werden auf einen Transportdorn aufgesteckt hängend durch den Heizofen 5 transportiert, wobei die Erwärmung von Infrarotheizstrahlern durchgeführt wird, die sich jeweils an der linken bzw. rechten Außenseite des Heizofens 5 befinden und in Richtung der Mittelachse des Heizofens 5 strahlen. Der Transport der Preforms durch den Heizofen 5 erfolgt außerdem um die Preformachse drehend, damit eine ungleiche Erhitzung der Seitenwände der Vorformlinge vermieden wird.The heater 5 is formed by a substantially rectangular heating furnace, wherein the preforms are guided through the furnace in two parallel opposing paths and the deflection from one to the other track at the upper end of the heating furnace 5 he follows. The preforms are attached to a transport mandrel hanging by the heater 5 transported, wherein the heating of infrared heaters is performed, each located on the left and right outside of the stove 5 located and in the direction of the central axis of the stove 5 radiate. The transport of the preforms through the stove 5 In addition, it rotates around the preform axis to prevent uneven heating of the side walls of the preforms.

Nach der Erwärmung der Preforms auf Verarbeitungstemperatur werden sie über einen Einlaufstern 25 an die Rotationsblasmaschine 6 übergeben. Die Blasformen, in denen die erwärmten Vorformlinge zu Behältern ausgeformt werden, sind auf einem Karussell angeordnet. Dabei werden die Vorformlinge an der Übergabestelle des Einlaufsterns 25 zum Karussell der Rotationsstreckblasmaschine 6 in die Blasform eingeführt und durch einen kombinierten Reck- und Blasvorgang zu einem Behälter ausgeformt. Es wird zu erst eine Vorblasluft eines geringeren Druckes in den Vorformling eingeführt, wodurch ein teilweises Ausprägen des Vorformlings zum Behälter vollzogen wird. In einem zweiten Schritt wird eine Fertigblasluft mit einem höheren Druck als die Vorblasluft in den Behälter eingeführt und dadurch an die Wandung der Blasformen gedrückt und zum Behälter ausgeformt. Nach dem Öffnen der Blasform wird der fertig geblasene Behälter aus der Form entnommen und dem Auslaufstern 26 übergeben, der den Behälter im Mündungsbereich unterstützt.After the preforms have been heated to the processing temperature, they are fed via an infeed star 25 to the rotary blowing machine 6 to hand over. The blow molds in which the heated preforms are formed into containers are arranged on a carousel. The preforms are at the transfer point of the inlet star 25 to the carousel of the rotary stretch blow molding machine 6 introduced into the blow mold and formed by a combined stretching and blowing to a container. It is first introduced a Vorblasluft a lower pressure in the preform, whereby a partial expression of the preform is performed to the container. In a second step, a finished blowing air having a higher pressure than the pre-blowing air is introduced into the container and thereby pressed against the wall of the blow molds and formed into the container. After opening the blow mold, the finished blown container is removed from the mold and the outlet star 26 passed, which supports the container in the mouth area.

Vom Auslaufstern 26 werden die Behälter an das Transferelement 10 übergeben, wobei eine teilungsgerechte Übergabe dadurch gewährleistet ist, dass das Transferelement 10 mit Halsgreifern für Behälter ausgerüstet ist. Bei den am Transferelement 10 angebrachten Halsgreifern handelt es sich um steuerbare Elemente.From the outlet star 26 the containers are attached to the transfer element 10 passed, whereby a division-fair transfer is ensured by the fact that the transfer element 10 equipped with neck grippers for containers. At the on the transfer element 10 attached neck claws are controllable elements.
