Description
Vorrichtung zur Herstellung von Tuben aus Kunststoff Vorrichtungen zur Herstellung von Tuben oder tubenähnlichen Verpackungen aus einem Stück erfordern die Zusammenfassung mehrerer Arbeitsgänge an ein und derselben Maschine, wenn eine vollautomatische Tuhenherstellung ermöglicht werden soll. Bisher mußten die einzelnen Arbeitsgänge an verschiedenen Maschinen ausgeführt werden. Nach der erfindungsgemäßen Vorrichtung sollen die verschiedenen Arbeitsgänge zum Zwecke der Vereinfachung der Tubenherstellung nicht mehr an verschiedenen Arbeitsgeräten vorgenommen werden, sondern mittels ein und derselben Vorrichtung ausgeführt werden.Device for the production of tubes from plastic devices for the production of tubes or tube-like packaging from one piece the combination of several operations on one and the same machine, if a fully automatic bag production is to be made possible. So far, the individual had to Operations are carried out on different machines. According to the invention Device are intended to perform the various operations for the purpose of simplifying the Tube production is no longer carried out on different tools, but are carried out by means of one and the same device.
Es ist eine Vorrichtung zum Abschneiden des Fortsatzes am Kopf von Tuben aus Kunststoff sowie zum Lochen des vom Fortsatz befreiten Tubenkopfes bekannt, bei der die zu bearbeitenden Tubenmäntel auf Dorne aufgesteckt werden, die auf einer Revolverkopfscheibe angeordnet sind, wobei die Aufsteckdorne jeweils mit einem in den Tubenkopf hinein ragenden Amboß versehen sind, der beim Abschneiden des Tubenfortsatzes den Tubenkopf gegen ein gegenüber der umlaufenden Revolverscheibe am Maschinengestell befestigtes und in der Kreisbahn der auf dem Dorn sitzenden Tubenkopf befindliches Messer abstützt. It is a device for cutting off the appendage on the head of Tubes made of plastic and known for punching the tube head freed from the extension, in which the tube jackets to be processed are placed on mandrels that are placed on a Turret disk are arranged, the mandrels each with an in the anvil protruding into the tube head are provided, which when the tube process is cut off the tube head against one opposite the revolving turret disk on the machine frame fixed and located in the circular path of the tube head sitting on the mandrel Knife supports.
Diese Vorrichtung gestattet nur die Verrichtung eines Arbeitsganges, des Abschneidens der Tubenfortsätze von Kunststofftuben, nicht aber das stets mehrere Arbeitsgänge erfordernde Anschweißen von Tubenköpfen an die Tubenmäntel. This device only allows one operation to be carried out cutting off the tube extensions from plastic tubes, but not always several Welding of tube heads to the tube jackets requiring operations.
Nach einer USA.-Patentschrift ist das Einbringen von Tubenköpfen gleich beim Herstellen des Kunststoffrohres, das erst später in die Abschnitte für die Tubenmäntel zertrennt wird, bekannt, indem die Tubenköpfe absatzweise dem Schlauchabschnitt einverleibt werden. Dies erfolgt bereits in dem Augenblick, da der Kunststoffschlauch für die Tubenmäntel aus der Spritzdüse austritt, wobei durch die Achse der Spritzdüse in regelmäßigen Abständen jeweils ein Tubenkopfstück mit Schulter in den noch warmen, elastischen Schlauch eingelegt wird, während der so mit Tubenköpfen versehene Schlauchabschnitt einfach um eine mit kontinuierlicher Geschwindigkeit rotierende Scheibe wie um ein Wagenrad läuft, ohne daß die bis zur Herstellung der fertigen Tube notwendigen weiteren Arbeitsgänge, wie das Trennen des Schlauches in einzelne Tubenabschnitte, das Verschweißen der Tubenköpfe mit dem Tubenmantel usw., in einem einzigen Arbeitsgang an der Vorrichtung erfolgen können. Diese Arbeitsgänge müssen an einer anderen Vorrichtung vorgenommen werden. According to a United States patent specification is the introduction of tube heads same as the manufacture of the plastic pipe, which is later added to the sections for the tube jacket is severed, known by the tube heads intermittently from the tube section be incorporated. This takes place at the moment when the plastic hose for the tube jackets exiting from the spray nozzle, through the axis of the spray nozzle at regular intervals a tube head piece with shoulder in the still warm, elastic tube is inserted, while the tube section provided with tube heads simply around a disc rotating at continuous speed like a The wagon wheel runs without the further necessary until the manufacture of the finished tube Operations such as separating the hose into individual tube sections, welding the tube heads with the tube jacket, etc., in a single operation on the device can be done. These operations must be carried out on a different device will.
Ferner ist eine Vorrichtung zur Tubenherstellung auf Grund einer schweizerischen Patentschrift bekannt, die zur Herstellung von Metalltuben dient und eine Vielzahl einzelner Bearbeitungsstationen aufweist. Diese Vorrichtung gestattet nicht die Herstellung beschickungsfertiger Tuben von dem aus Spritzdüse kommenden Schlauchabschnitt, insbesondere nicht das Verschweißen bzw. Verbinden von Tubenkopf und Tubenmantel, sondern dient nur der Weiterbearbeitung vorgearbeiteter Tubenrohlinge, bei denen bereits Tubenkopf und Tubenmantel anderweitig hergestellt worden sind. Die Vorrichtung ist daher zur vollautomatischen Herstellung von Kunststofftuben ungeeignet. Furthermore, a device for tube production is based on a Swiss patent known which is used for the production of metal tubes and has a plurality of individual processing stations. This device allows not the production of ready-to-load tubes from the one coming out of the spray nozzle Hose section, in particular not the welding or connection of the tube head and tube jacket, but is only used for the further processing of pre-machined tube blanks, where the tube head and tube jacket have already been manufactured elsewhere. The device is therefore for the fully automatic production of plastic tubes not suitable.
Außer diesen, nur eine Teil bearbeitung der herzustellenden Tuben gestattenden Vorrichtungen sind zur Herstellung von Tuben aus thermoplastischem Material Vorrichtungen bekannt, bei denen die Schlauchabschnitte manuell auf lose Dorne gezogen und mittels eines Rundtisches durch einen Wärmekanal geführt werden. Nach Verbördelung des Schlauchüberstandes wird dann die Tubenschulter von Hand aufgesetzt und mit dem Schlauch mittels einer Schweißpresse verbunden. Nach erfolgter Verschweißung werden die Tuben von Hand abgezogen und zur Weiterverarbeitung gegeben. Apart from these, only a partial processing of the tubes to be produced Permitting devices are used to manufacture tubes from thermoplastic Material devices known in which the hose sections are manually loosely Mandrels are pulled and guided through a heat channel by means of a rotary table. After the hose protrusion has been crimped, the tube shoulder is then put on by hand and connected to the hose by means of a welding press. After welding the tubes are pulled off by hand and given for further processing.
Weiterhin ist ein etwas rationelleres Verfahren bekannt, bei dem wieder von besonders gefertigten Schlauchabschnitten ausgegangen wird, die, auf Dorne gezogen und mit zusätzlichem Kunststoffmaterial versehen, unter eine Schweißpresse gelangen, wo die Tuben schulter und der Verschluß mittels Hochfrequenz geformt und gleichzeitig mit dem Schlauch verbunden werden. Auch dieses Verfahren hat den Nachteil, daß infolge der längeren Abkühlung und infolge des Aufziehens der Tubenkörper von Hand auf die Dorne eine rationelle Fertigung nicht möglich ist und die Haltbarkeit der Verbindung von Tubenkörper und Tubenschulter nicht mit Sicherheit gewährleistet werden kann. Furthermore, a somewhat more rational method is known in which is again assumed from specially manufactured hose sections, on Mandrels drawn and provided with additional plastic material, under a welding press get where the tubes shoulder and the closure formed by means of high frequency and connected to the hose at the same time. This procedure too Has the disadvantage that as a result of the prolonged cooling and as a result of the pulling up of the Tube body by hand on the mandrels an efficient production is not possible and the durability of the connection between the tube body and tube shoulder is not certain can be guaranteed.
Die erfndüngsgemäße Vorrichtung ermöglicht die Herstellung von Tuben aus thermoplastischem Kunststoff, wobei vollautomatisch von einer beliebig großen Rolle ein Schlauch in die Vorrichtung eingb führt und entsprechend der gewünschten Tubenlänge automatisch abgetrennt wird, während an einer anderen Arbeitsstation ein und derselben Maschine eine fertige Tubenschulter mit dem Schlauchabschnitt verschweißt und die fertige Tube automatisch aus der Vorrichtung ausgestoßen wird. The device according to the invention enables tubes to be produced made of thermoplastic plastic, being fully automatic from any size Roll a hose into the device and according to the desired Tube length is automatically cut off while at another work station one and the same machine a finished tube shoulder with the tube section welded and the finished tube is automatically ejected from the device.
Die erfindungsgemäße Vorrichtung zum Herstellen von Kunststofftuben besteht aus einem Werkzeugträger und einem beweglich und vertikal angeordneten Halteorgan, das die zu bearbeitenden Schlauchabschnitte den einzelnen Bearbeitungsstationen in an sich bekannter Weise nach dem Revolverkopfprinzip nacheinander zuführt, und ist dadurch gekennzeichnet, daß als Halteorgan über Kreuz angeordnete, gemeinsam drehbare Tragdorne 2 nach Art des Revolverkopfes 1 vorgesehen sind und um die Tragdorne herum in deren Verlängerung, in Drehrichtung der Tragdorne gesehen, nacheinander eine Schneidevorrichtungen 8, 9, 10, eine Zuführeinrichtung 13 für die vorgefertigten Tubenschultern 12, ein Hochfrequenzschweiß gerät 17 und ein Abblasrohr 18 für die fertigen Tuben vorgesehen sind. The device according to the invention for producing plastic tubes consists of a tool carrier and a movable and vertically arranged holding element, that the hose sections to be processed to the individual processing stations feeds one after the other in a manner known per se according to the turret head principle, and is characterized in that as a holding member arranged crosswise, together rotatable support mandrels 2 are provided in the manner of the turret head 1 and around the support mandrels around in their extension, seen in the direction of rotation of the lifting mandrels, one after the other a cutting device 8, 9, 10, a feed device 13 for the prefabricated Tube shoulders 12, a high-frequency welding device 17 and a blow-off pipe 18 for the finished tubes are provided.

Die Schneidvorrichtung zum Abtrennen des Schlauchabschnittes vom endlosen Band besteht aus der vom Ende des fliegenden Dornes7 gebildeten Schneidkante 10 und deren im Umfang des Schneidringes 9 angeordneten Messern 11. The cutting device for separating the hose section from endless band consists of the cutting edge formed by the end of the flying mandrel 7 10 and their knives 11 arranged in the circumference of the cutting ring 9.
Am Kopf des Werkzeugträgers 1 ist eine Tubenschulterzuführungseirrichturg in Form eines Tubenschultermagazlns 13 vorgesehen. An Stelle des Tubenschiiltermagazins kann eine Spritzgießvorrichtung vorgesehen sein, falls nicht vorgefertigte Tubenschultern mit dem Tubenmantel verbunden werden sollen. Bei dem Tubenschultermagazin entfallen die Tubenschultern dem Magazin entsprechend den Arbeitstakten des Revolverkopfkreuzes auf Grund der eigenen Schwerkraft. At the head of the tool carrier 1 is a tube shoulder feed device provided in the form of a tube shoulder magazine 13. Instead of the tube filter magazine An injection molding device can be provided, if not prefabricated tube shoulders to be connected to the tube jacket. No need for the tube shoulder magazine the tube shoulders to the magazine according to the work cycles of the turret cross due to its own gravity.

The device according to the invention points to the last work station a blow-off device 18 which is designed in the form of a blow-off pipe to to ensure quick removal of the finished tube from the working mandrel.
Unterhalb des Werkzeugträgers 1 kann ein Förderband zum Abtransport der Tuben vorgesehen sein. Below the tool carrier 1, a conveyor belt can be used for removal the tubes be provided.
Fig. 1 zeigt die erfindungsgemäße Vorrichtung in Seitenansicht; Fig. 2 zeigt die AbtrennvorrichEtung mit der Zuführvorrichtung als Ausschnitt von Fig. 1 in Seitenansicht. Fig. 1 shows the device according to the invention in side view; Fig. 2 shows the separation device with the feed device as a detail from FIG. 1 in side view.
Die Tubenherstellung geschieht wie folgt: Wie in Fig. 1 dargestellt, wird an der ersten Station das Aufstecken der aus der Rolle 4 abgewickelten Schlauchfolie auf den Dorn 2 mittels des fliegenden Dornes 7 unter Führung und Fixierung mittels zweier im rechten Winkel zueinander liegender Rollenpaare 8 unter Einschaltung als Vorschubgerät 6 bewirkt. Das Vorschubgerät 6 gibt jeweils einen Schlauchabschnitt von einer vorher durch Anschlag festgelegten Länge frei, die genau der gewünschten Tuberdänge entspricht. The tubes are produced as follows: As shown in Fig. 1, at the first station, the tubular film unwound from the roll 4 is put on on the mandrel 2 by means of the flying mandrel 7 under guidance and fixation by means two pairs of rollers 8 lying at right angles to one another, including as Feed device 6 causes. The feed device 6 is each a hose section from a length determined beforehand by a stop that is exactly the desired Corresponds to tuber length.
Mit dem Aufbringen des Schlauchstückes auf den fliegenden Dorn 7 wird dieses zugleich derart aufge weitet, daß es auf den Tragdorn 2 paßt. Ein zwischen fliegendem Dorn 7 und Tragdorn 2 angeordneter rotierender Schneidring 9 hat dabei die Aufgabe, nach Erreichung der vorbestimmten Länge den Schlauchabschnitt 3 entlang der Schneidkante 10 des fliegenden Dornes 7 abzutrennen, indem die im Umfang des Schneidringes 9 angeordneten Messer 11 in die Schneidkante gedrückt werden. Nach der Trennung wird das Vorschubgerät 6 zurückgezogen und der Revolverkopf automatisch weitergeschaltet, so daß der Tragdorn 2 mit dem abgetrennten Schlauchstück die nächste Arbeitsstation erreicht. Auf dieser zweiten Station wird, wie Fig. 1 zeigt, der den Tubenrumpf bildenden Schlauchabschnitt 3 mit der Tubenschulter 12 versehen. With the application of the hose section to the flying mandrel 7 this is at the same time expanded in such a way that it fits on the support mandrel 2. One between rotating cutting ring 9 arranged with flying mandrel 7 and support mandrel 2 the task of following the tube section 3 after the predetermined length has been reached the cutting edge 10 of the flying mandrel 7 to be separated by the in the circumference of the Cutting ring 9 arranged knife 11 are pressed into the cutting edge. To the separation, the feed device 6 is withdrawn and the turret head automatically switched so that the support mandrel 2 with the separated piece of hose the next Workstation reached. At this second station, as shown in FIG. 1, the the tube section 3 forming the tube body is provided with the tube shoulder 12.
Zu diesem Zweck gibt das die Tubenschulter 12 enthaltende Tubenschultermagazin 13 eine Tubenschulter mittels eines Rasthebels 14 frei, und zwar erfolgt die Freigabe automatisch nach jedem Umschaltvorgang des Revolverkopfes, sobald der Schlauchabschnitt 3 unter dem Schultermagazin 13 steht. Die Tubenschulter wird zugleich beim Einsetzen in den Schlauchabschnitt 3 durch den Tragdorn 2 zentriert und fällt konzentrisch in den Schlauchüberstand hinein. Zur Erleichterung des Einführens ist die Tubenschulter 12 im Durchmesser kleiner als der Innendurchmesser des Schlauchabschnittes 3 gehalten. For this purpose there is the tube shoulder magazine containing the tube shoulder 12 13 free a tube shoulder by means of a locking lever 14, and the release takes place automatically after each switching process of the turret head as soon as the hose section 3 is under the shoulder magazine 13. The tube shoulder is at the same time when inserting centered in the hose section 3 by the support mandrel 2 and falls concentrically into the hose overhang. The tube shoulder is to facilitate insertion 12 kept smaller in diameter than the inner diameter of the hose section 3.
Nach Beschickung des Schlauchstückes 3 mit der Tubenschulter 12 wird der Revolverkopf zur dritten Arbeitsstation weitergeschaltet. Hier erfolgt die Verschweißung der Tubenschulter 12 mit dem Tubenmantel 3. Die Formelektrode 17 bördelt die überstehenden Kanten des Tubenmantels 3 über den Rand der Tubenschulter 12. Nach Abschluß des Schweißvorganges und der notwendigen Abkühlung schaltet der Revolverkopf auf die vierte Arbeitsstation, wo der Tubenausstoß erfolgt, indem die Tuben durch eine Abblasvorrichtung 18 abgeblasen und durch ein Förderband abtransportiert werden. After charging the tube 3 with the tube shoulder 12 is the turret indexed to the third workstation. The welding takes place here the tube shoulder 12 with the tube jacket 3. The shaped electrode 17 flanges the protruding Edges of the tube jacket 3 over the edge of the tube shoulder 12.
