Description

Die Erfindung betrifft eine Vorrichtung zum Schweißen von Kopfnähten bei Beuteln, insbesondere bei Steh- und Siegelrandbeuteln, mittels Ultraschall.The invention relates to a device for welding head seams in bags, especially in standing and sealed edge bags, by means of ultrasound.

Bisher wurden auf horizontalen Füllmaschinen für Steh- und Siegelrandbeutel bereits Ultraschall-Schweißvorrichtungen eingesetzt. Diese Vorrichtungen waren als Einzelkomponenten in die Maschinen integriert. Das heißt, es bestanden diverse mechanische und elektrische Schnittstellen zwischen den Ultraschall-, Mechanik- und elektrischen Funktionen.So far, ultrasonic welding devices have already been used on horizontal filling machines for upright and sealed-edge bags. These devices were integrated as individual components in the machines. That is, there were various mechanical and electrical interfaces between the ultrasonic, mechanical and electrical functions.

Die Ultraschall-Schweißvorrichtungen mussten also als Sondervorrichtungen an jede Maschine angepasst werden. Um den Beutel zwischen die Sonotrode und den Amboss einführen zu können, wird die Schweißvorrichtung üblicherweise weit geöffnet oder angehoben, so dass es beim Heranfahren des Beutels zu keiner Kollision mit den Schweißwerkzeugen kommt. Für diese Hubbewegung ist ein Antrieb erforderlich. Außerdem müssen der Amboss und die Sonotrode bewegt werden, wofür nochmals Antriebe erforderlich sind. Diese Antriebe sind mit einer Steuerung verbunden und werden über diese synchron zum Fördertakt der Maschine angesteuert. Der Aufwand an Bauteilen und Programmierung der Steuerung ist relativ hoch. Außerdem beeinträchtig das weite Öffnen der Schweißwerkzeuge zum Einführen der Beutel den Schweißzyklus negativ.The ultrasonic welding devices had to be adapted as special devices to each machine. In order to be able to insert the bag between the sonotrode and the anvil, the welding device is usually opened or raised so that there is no collision with the welding tools as the bag approaches. For this stroke movement a drive is required. In addition, the anvil and the sonotrode must be moved, which again drives are required. These drives are connected to a controller and are controlled by these synchronously to the delivery cycle of the machine. The complexity of components and programming of the controller is relatively high. In addition, the wide opening of the welding tools for inserting the bags adversely affects the welding cycle.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung bereit zu stellen, die auf einfach Weise in horizontale Füllmaschinen integrierbar ist.The invention has for its object to provide a device that can be easily integrated into horizontal filling machines.

Diese Aufgabe wird erfindungsgemäß mit der eingangs genannten Vorrichtung zum Schweißen von Kopfnähten bei Beuteln mittels Ultraschall gelöst, indem die Vorrichtung ausgerüstet ist mit einer Ultraschallsonotrode und einem Amboss, wobei zwischen der Ultraschallsonotrode und dem Amboss ein den Beutel aufnehmender Spalt herrscht, mit einer den Amboss tragenden Führung und einem an dieser Führung verschieblich gelagerten und die Ultraschallsonotrode tragenden Schlitten, wobei der Schlitten gegenüber der Führung mittels eines Antriebs derart verschiebbar ist, dass die Ultraschallsonotrode in Richtung des Ambosses oder weg von diesem verlagerbar ist, indem der Antrieb sowohl an der Führung als auch am Schlitten angreift.This object is achieved with the above-mentioned device for welding head seams in bags by means of ultrasound by the device is equipped with an ultrasonic sonotrode and an anvil, wherein between the ultrasonic sonotrode and the anvil a bag receiving gap prevails, with a supporting the anvil Guide and slidably mounted on this guide and carrying the ultrasonic sonotrode slide, wherein the carriage relative to the guide by means of a drive is displaced so that the ultrasonic sonotrode in the direction of the anvil or away from this is displaceable by the drive both on the guide and on the sled attacks.

Die erfindungsgemäße Vorrichtung bildet eine in sich geschlossene Funktionseinheit. Die Vorrichtung kann als Modul gebaut und getestet werden und anschließend mittels definierten Schnittstellen in die Verpackungsmaschine integriert werden. Dabei bilden die Schnittstellen von Ultraschall, Mechanik und Steuerung ein geschlossenes System. Dadurch verbessert sich die Prozessbeherrschung und die Integrierbarkeit des Ultraschallprozesses (z. B. Ausrichtung der Schweißkomponenten). Horizontale Füllmaschinen kommen heute als Längsläufer oder Rundläufer mit Rundschalttisch zum Einsatz. Je nach Maschinenkonzept muss die Schweißvorrichtung aus der Bewegungskontur der Stehbeutel gefahren, d. h. angehoben werden, um Kollisionen zu vermeiden. Bei der erfindungsgemäßen Vorrichtung erfolgt dies im Gegensatz zu anderen bekannten Systemen mit nur einem Antrieb, welcher die Bewegungen über ein Schwenksystem erzeugt. Dies erlaubt schnellere und präzisere Schließbewegungen des Ultraschall-Schweißsystems.The device according to the invention forms a self-contained functional unit. The device can be built and tested as a module and then integrated into the packaging machine by means of defined interfaces. The interfaces of ultrasound, mechanics and control form a closed system. This improves the process control and the integratability of the ultrasonic process (eg alignment of the welding components). Horizontal filling machines are used today as longitudinal or rotary machines with rotary indexing table. Depending on the machine concept, the welding device must be moved out of the motion contour of the stand-up pouches, ie. H. be raised to avoid collisions. In the device according to the invention this is in contrast to other known systems with only one drive, which generates the movements of a pivot system. This allows faster and more precise closing movements of the ultrasonic welding system.
