B. aus Polyäthylen, nach denen zum Verschließen der Beutelenden der Schlauch örtlich zusammengerafft, an dieser Stelle verschweißt und gleichzeitig in Querrichtung zum Schlauch durchschnitten wird. Bei diesen Verfahren werden also zwei benachbarte Enden aufeinanderfolgender Beutel in einem Arbeitsgang gebildet und verschlossen. Der verarbeitete Schlauch kann ein Folien- oder Netzschlauch sein.Separating welding device for the production of round bags in pairs Made of thermoplastic material Methods are known for producing round bags made of thermoplastic plastic hoses, e.g. B. made of polyethylene, after which to Seal the ends of the bag with the hose gathered together locally, at this point is welded and cut at the same time in the transverse direction to the hose. at these methods thus produce two adjacent ends of consecutive bags formed and sealed in one operation. The processed hose can be a Be foil or mesh tubing.

Zum Stand der Technik gehören Trennschweißmaschinen, die im wesentlichen aus zwei dicht nebeneinanderliegenden ortsfesten Klemmvorrichtungen zur Aufnahme des Kunststoffschlauches und einem zwischen diesen in einer zu deren Abstandstrecke senkrechten Ebene verschiebbar angeordneten heizbaren Schweißmesser bestehen. Die Schweißstelle kann mit Luft oder durch Berührung mit einem kalten metallischen Körper gekühlt werden. Bei dieser bekannten Vorrichtung wird die Leistung in erster Linie von der Schweiß- bzw. Kühlzeit bestimmt, beides Größen, die sehr stark von der Stärke des zusammengerafften Schlauches abhängen.The state of the art includes cut-off welding machines that essentially consisting of two stationary clamping devices located close to one another for receiving of the plastic tube and one between them in a distance to their distance vertical plane displaceably arranged heated welding knife exist. the Welding point can be done with air or by contact with a cold metallic body be cooled. In this known device, the performance is primarily determined by the welding or cooling time, both sizes that are very much dependent on the strength of the gathered hose.

Erfindungs" ser Vorrichtung mehrere Klemmstellen für die zusammengerafften Schlauchabschnitte von doppelter Beutellänge auf zwei dicht nebeneinanderliegenden rotierenden Kreisscheiben angeordnet. Das beheizte Schweißmesser ist ortsfest installiert. Seine Länge bestimmt die Schweißzeit. Ebenso ist ein Gebläse mit nachfolgender Düse ortsfest installiert. Durch die Rotation der Kreisseheiben wird das zu verschwei-Ü )ende Material der Heiz- und Kühlzone nacheinander zugeführt. Durch eine Variation folgender Größen, Durchmesser der Kreisscheiben, Anzahl der Klemmstellen auf dem Umfang, Länge des beheizten Schweißmessers und Ausbilduno, der Kühldüse kann jede beliebige Maschinenleistung erzielt werden.The performance of the device according to the invention, on the other hand, is independent of the welding and cooling time and thus of the strength of the together with the "erafften hose. Invention" this device several clamping points for the gathered tube sections from double the bag length to two tightly arranged adjacent rotating circular disks. The heated welding knife is permanently installed. Its length determines the welding time. Likewise is a fan Stationary installed with downstream nozzle. By rotating the circular disks the material to be welded is fed to the heating and cooling zones one after the other. By varying the following sizes, diameter of the circular disks, number of Clamping points on the circumference, length of the heated welding knife and training, Any machine output can be achieved with the cooling nozzle.

Ein Ausführungsbeispiel der Trennschweißmaschine gemäß der Erfindung, ist in F i g. 1 bis 6 C el dargestellt, und zwar zeigt F i g. 1 die Seitenansicht der Vorrichtung, F i g. 2 die Vorderansicht der Vorrichtung, F i g. 3 bis 5 einen Ausschnitt der Seitenansicht F i g. 1 mit Einlegevorrichtung in drei verschiedenen Arbeitsphasen der Vorrichtung, F i g. 6 Draufsicht des Ausschnitts F i g. 4 mit teilweisem Schnitt. Auf zwei auf einer Drehachse in geringem Ab- stand nebeneinander befindlichen Kreisseheiben 1 sind je mehrere, z. B. acht Klemmhebel 2 mit je einer Klemmbacke3angeordnet. DieseKlemmbacke3preßt den zusammengerafften Schlauchabschnitt während des Trennschweißvorganges in die Nut 17. Die Klemmhebe12 sind auf einem Zapfen4 drehbar gelagert und auf der Gegenseite der Klemmbacken mit einer Rolle 5 versehen. Die Rollen 5 laufen bei Rotation der Kreisscheiben 1, durch Federn 6 angedrückt, auf einer festen Kurvenscheibe 7 ab. Diese Kurvenscheibe 7 bewirkt, daß die Klemmbacken 3 in einem in seiner Größe und Lage durch die Kurvenscheibe 7 bestimmten Winkel a die Nut 17 freigeben bzw. in dem Winkel ß die Nut 1-7 verschließen. Auf dem Bogen des Winkels fl sind ein Schweißmesser 11 und eine Kühldüse 12 an-eordnet.An embodiment of the cut-off welding machine according to the invention is shown in FIG. 1 to 6 C el shown, namely shows F i g. 1 shows the side view of the device, FIG. 2 shows the front view of the device, FIG. 3 to 5 show a detail of the side view F i g. 1 with insertion device in three different working phases of the device, FIG . 6 Top view of the section F i g. 4 with partial cut. Two on a rotational axis at a small distance-juxtaposed Kreisseheiben 1 are sorted several such. B. eight clamping levers 2, each with a clamping jaw 3 arranged. This clamping jaw 3 presses the gathered hose section into the groove 17 during the separation welding process. The clamping levers 12 are rotatably mounted on a pin 4 and are provided with a roller 5 on the opposite side of the clamping jaws. When the circular disks 1 rotate, the rollers 5 run on a fixed cam disk 7, pressed on by springs 6 . This cam disk 7 causes the clamping jaws 3 to release the groove 17 at an angle α determined in its size and position by the cam disk 7 or to close the groove 1-7 at the angle β. A welding knife 11 and a cooling nozzle 12 are arranged on the arc of the angle f1.

Von einem Schlauchvorrat werden zwei zusammenhängende Beutellängen 15 abgetrennt, ein Arbeitsgang, der maschinell oder von Hand erfolgen kann. Dieses Schlauchstück 15 wird zusammengerafft und auf halber Län-e in eine Einlegevorrichtung 8 gebracht. Die Einlegevorrichtung 8 kann beliebig gestaltet werden, die aufgeführte Vorrichtung soll nur ein Beispiel sein. Sie hat die Aufgabe, den Schlauchabschnitt 15 in einer bestimmten Lage festzuhalten, so daß die an den Klemmstellen der am Schweißmesser 11 vorbeirotierenden Scheiben 1 hervorspringenden Nasen 16 den Schlauch 15 erfassen können (F i g. 3). Der Schlauch 15 gleitet dann in die tiefste Stelle der Nut 17 (F i g. 4) und wird von dem Hebel 2 mit der Klemmbacke 3 dort festgehalten und gleichzeitig von der Einlegevorrichtung freigegeben (F i g. 5). Die rotierenden Scheiben führen den zusammengerafften Schlauch nun dem zwischen den beiden Scheiben ortsfest installierten Schweißmesser 11 zu, das so angeordnet ist, daß es langsam durch den zu schweißenden Schlauch 15 hindurchdringt. Es trennt den Schlauch 15 in zwei Abschnitte gleicher Länge und schweißt gleichzeitig diese Schlauchabschnitte im zusammengerafften Zustand an den Schnittstellen zu, so daß zwei einseitig verschlossene Rundbeutel gebildet werden. Im Bereich der Kühldüse12 werden die Schweißstellen gekühlt. Die fertigen Beutel werden von der Klenunbacke 3 freie Glegeben und können von Hand oder durch eine Vorrichtung 13 den Kreisscheiben 1 entnommen und einem Vorratsbehälter 14 zugeleitet werden.Two connected bag lengths 15 are separated from a hose supply, an operation that can be carried out by machine or by hand. This piece of hose 15 is gathered together and brought into an insertion device 8 halfway along its length. The insertion device 8 can be designed in any way, the device listed is only intended to be an example. It has the task of holding the hose section 15 in a certain position so that the lugs 16 protruding from the clamping points of the discs 1 rotating past the welding knife 11 can grip the hose 15 ( FIG. 3). The hose 15 then slides into the lowest point of the groove 17 ( FIG. 4) and is held there by the lever 2 with the clamping jaw 3 and at the same time released by the insertion device (FIG . 5). The rotating disks now feed the gathered tube to the welding knife 11 , which is fixedly installed between the two disks and which is arranged so that it slowly penetrates through the tube 15 to be welded. It separates the tube 15 into two sections of equal length and at the same time welds these tube sections in the gathered state at the interfaces, so that two round bags closed on one side are formed. The welds are cooled in the area of the cooling nozzle12. The finished bags are released from the Klenun jaw 3 and can be removed from the circular disks 1 by hand or by a device 13 and fed to a storage container 14.
