Abstract
Die Erfindung betrifft ein Verfahren zum Staubentfernen von der Flaeche eines Ventilsackes, auf die die Sauggreifer zum OEffnen und Manipulieren des Ventilsackes angreifen, indem waehrend der Abwaertsbewegung der Sauggreifer durch diese senkrecht Luft auf die Sackoberflaeche geblasen wird.{Ventilsack; Luft; Staubentfernung; OEffnen; Manipulieren; Sauggreifer}The invention relates to a method for removing dust from the surface of a valve bag, on which the suction grippers act to open and manipulate the valve bag by blowing perpendicularly air onto the bag surface during the downward movement of the suction gripper.

Description
Zum Verpacken von körnigen und pulverförmigen Produkten, wie Zement, Plastgranulat oder Zucker, warden vielfach Säcke aus Papier, Kunststoff oder Fasern verwendet.For packing of granular and powdered products, such as cement, plastic granulate or sugar, sacks of paper, plastic or fibers are often used.
Für das Öffnen und Manipulieren der Ventilsäcke wurden bisher verschiedene Lösungen gefunden, die jedoch nicht in jedem Fall den Praxisanforderungen gerecht werden. So können z. B. nicht ohne aufwendige Zusatzeinrichtungen Stäube von den Oberflächen der Ventilsäcke entfernt werdon.For the opening and manipulation of the valve bags different solutions have been found, but not always meet the practical requirements. So z. For example, dusts are not removed from the surfaces of the valve sacks without complicated additional equipment.
In der DE-OS 2615365 (B 08 B, 5/00) wird eine „Maschine zum Beseitigen von Staub von Blattmaterial" beschrieben. Hier wird eine Aufwirbelung des Staubes durch Bi sen über die gesamte Oberfläche des Materials realisiert. Zusätzlich ist hierbei eine gesonderte Absaugvorrichtung notwenug, da ansonsten die Sauggreifer ein Staub-Luft-Gemisch einsaugen, wodurch Störungen durch Verstopfung vorprogrammiert sind.DE-OS 2615365 (B 08 B, 5/00) describes a "machine for removing dust from sheet material." In this case, a whirling up of the dust is realized by biting over the entire surface of the material Absaugvorrichtung neces sary, otherwise the suction pads suck in a dust-air mixture, which disturbances are blocked by constipation.
In der CH-PS 649725 (B 08 B, 5/02) wird eine Einrichtung zum kontaktlosen Entfernen von Staub von einer Materialbahn oder der Oberfläche eines verhältnismäßig flachen Gegenstandes mit einem auf die Materialbahn oder den Gegenstand gerichteten Luftgebläse in Kombination mit einem gepulsten Luftstrom erzeugenden Luftwandler beschrieben. Mit dieser Vorrichtung wird ein guter Reinigungseffekt erzielt, jedoch ist diese Vorrichtung nur mit zusätzlichen Einrichtungen zum Öffnen und Manipulieren der Ventilsäcke anwendbar.In CH-PS 649725 (B 08 B, 5/02) is a device for the contactless removal of dust from a material web or the surface of a relatively flat object with a directed onto the web or the object air blower in combination with a pulsed air flow generating Luftwandler described. With this device, a good cleaning effect is achieved, however, this device is only applicable with additional facilities for opening and manipulating the valve bags.
Ziel der Erfindung ist es, Stäube von der Fläche eines Ventilsackes zu entfernen, in Kombination mit dem Aufnehmen, Manipulieren und Öffnen der Ventilsäcke zum Zwecke der Befüllung und Verpackung in automatischen Absackmaschinen.The aim of the invention is to remove dust from the surface of a valve bag, in combination with receiving, manipulating and opening the valve bags for the purpose of filling and packaging in automatic bagging machines.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Staubentfernung von der Fläche eines Ventilsackes zu entwickeln, das universell für Absackautomaten unterschiedlicher Bauweise anwendbar sein soll.The invention has for its object to develop a method for removing dust from the surface of a valve bag, which should be universally applicable for bagging machines of different construction.
Die Aufgabe wird dadurch gelöst, daß auf die Ventilsäcke, die in bekannter Weise durch Sauggreifer zum Öffnen und Manipulieren aufgenommen werden, während der Abwärtsbewegung der Sauggreifer durch diese senkrecht Luft auf die Sackoberfläche geblasen wird.The object is achieved in that on the valve bags, which are received in a known manner by suction pads for opening and manipulating, while the downward movement of the suction pads is blown through this perpendicular air to the bag surface.
Nach Erreichen der vorbestimmten Höhe wird von Blasen auf Saugen umgeschaltet, wodurch die Ventiloberfläche angesaugt wird. Der Greifer wird nunmehr mit dem Ventilsack aufwärts bewegt. Während der Aufwärtsbewegung wird durch Verkleinerung des Winkels zwischen den parallel zueinander angeordneten Sauggreifern der Ventilsack angehoben und das Ventil geöffnet.After reaching the predetermined height is switched from bubbles to suction, whereby the valve surface is sucked. The gripper is now moved upwards with the valve bag. During the upward movement, the valve bag is raised and the valve is opened by reducing the angle between the suction pads arranged parallel to one another.
Der geöffnete Ventilsack wird nun nach bekannter Technologie auf den Abfüllstutzen einer Absackmaschine aufgezogen. Hierzu ist kein zusätzlicher Mechanismus erforderlich, eine Zwischenübergabe oder ein Umgreifen erfolgt nicht.The opened valve bag is now mounted on the filling nozzle of a bagging machine according to known technology. For this purpose, no additional mechanism is required, an intermediate transfer or embrace does not take place.
