Abstract
Description
Die Erfindung bezieht sich auf eine Beutelkette, die aus einer Vielzahl von aus einer Kunststofffolie hergestellten Beuteln, die schuppenartig übereinander liegend an mindestens zwei mit seitlichem Abstand zueinander angeordneten antreibbaren Tragbändern lösbar befestigt sind, besteht, wobei die Öffnungen der Beutel etwa senkrecht zu den Tragbändern ausgerichtet sind.The invention relates to a bag chain consisting of a plurality of bags made of a plastic film, the scale-like superimposed on at least two laterally spaced drivable carrying straps are releasably secured, wherein the openings of the bag aligned approximately perpendicular to the straps are.
Durch die
Zum Einführen eines zu verpackenden Gutes in einen Beutel sind in einer ersten Phase auf einer oder beiden Seiten des Beutels Saugheber anzusetzen, mittels denen der Beutel soweit zu öffnen ist, dass Greifer zum weiteren Öffnen mechanisch in diesen eingeführt werden können. In dieser ersten Phase können die zum Öffnen des Beutels erforderlichen Kräfte jedoch außerordentlich hoch sein, da Luft eventuell nicht schnell genug in den Beutel strömt und ein Unterdruck entsteht, der den Öffnungskräften entgegenwirkt. Der Unterdruck wird hierbei umso höher, je schneller der Beutel geöffnet bzw. die Sauggreifer auf der einen Seite und die Sauggreifer und/oder die Tragbänder auf der anderen Seite mit einer Öffnungsgeschwindigkeit auseinander bewegt werden. Ein schnelles Öffnen der Beutel ist jedoch beim automatisierten Öffnungsvorgang erwünscht, da eine hohe Produktivität des Prozesses zu erzielen ist.For introducing a product to be packaged in a bag, in a first phase suction cups are to be placed on one or both sides of the bag, by means of which the bag is to be opened so far that grippers can be mechanically inserted into them for further opening. In this first phase, you can open the bag However, forces required to be extremely high, because air may not flow fast enough into the bag and a negative pressure is created, which counteracts the opening forces. The vacuum is in this case the higher the faster the bag is opened or the suction pads on one side and the suction pads and / or the straps on the other side are moved apart at an opening speed apart. However, a quick opening of the bags is desirable in the automated opening process, since a high productivity of the process can be achieved.
Bei zu hoch werdender Öffnungskraft werden die Beutel aber in dieser Öffnungsphase entweder von den Tragbändern abgerissen, insbesondere dann, wenn auf dieser Beutelseite keine zusätzlichen Sauggreifer zum Einsatz kommen, oder aber die Sauggreifer verlieren den Beutel. Insbesondere das Abreißen des Beutels tritt oftmals auf. Mittelbare Ursache hierfür ist, dass die Beutel mit Rücksicht auf die gute Verarbeitbarkeit gegeneinander sehr gut gleiten müssen und hierzu Gleitmittel einzusetzen sind, durch die jedoch die Haltekraft an den Tragbändern beeinträchtigt wird. Das gute Gleitverhalten ist erforderlich, wenn beim Öffnen der Beutel regelmäßig der unterste Beutel unter den darauf liegenden Beuteln weggezogen werden muss, ohne dass die Beutelkette bzw. deren Schuppung ihren Ordnungszustand durch Einwirkung, insbesondere von ruckartigen Querkräften verliert.If the opening force is too high, however, the bags are torn off either by the straps in this opening phase, especially when no additional suction pads are used on this side of the bag, or else the suction pads lose the bag. In particular, the tearing of the bag often occurs. The indirect reason for this is that the bags have to slide very well against each other in view of the good processability and lubricants are to be used, by which, however, the holding force on the straps is impaired. The good sliding behavior is required if the bottom bag under the bag lying on it must be regularly pulled away when opening the bag without the bag chain or its scaling loses its order state by the action, in particular jerky shear forces.
Der Einsatz der bekannten Schlauchbeutelkette zum Verpacken von Lebensmitteln ist daher oftmals, obwohl diese Beutelkette in der Praxis vielseitig verwendet wurde und sich auch bewährt hat, bei mit hoher Geschwindigkeit durchgeführten Abpackvorgängen mit erheblichen Schwierigkeiten verbunden.The use of the known tubular bag chain for food packaging is therefore often, although this bag chain has been used in many ways in practice and has also proven itself associated with high-speed packaging operations associated with considerable difficulties.
Es ist demnach Aufgabe der Erfindung, die Beutelkette der vorgenannten Gattung in der Weise auszugestalten, dass die Beutel auch bei hohen Arbeitsgeschwindigkeiten stets gut zu öffnen sind. Es soll somit mit einfachen Mitteln erreicht werden, dass ein Aneinanderkleben der die Beutel bildenden Folie nahezu ausgeschlossen ist. Das Öffnen der Beutel soll vielmehr störungsfrei ermöglicht werden.It is therefore an object of the invention to design the bag chain of the aforementioned type in such a way that the bags are always easy to open even at high operating speeds. It should therefore be achieved by simple means that a sticking together of the film forming the bag is almost impossible. The opening of the bag should rather be made trouble-free.
Gemäß der Erfindung wird dies bei der Beutelkette der eingangs genannten Art dadurch erreicht, dass die die Beutel bildende Folie auf einer oder beiden Innenseiten, gegebenenfalls auch auf einer oder beiden Außenseiten des Beutels, mit in diese eingebundenen Abstandshaltern versehen ist.According to the invention, this is achieved in the bag chain of the type mentioned above in that the film forming the bag is provided on one or both inner sides, optionally also on one or both outer sides of the bag, with spacers incorporated therein.
Die Abstandshalter können hierbei durch ein anorganisches oder organisches Antiblockmittel, beispielsweise synthetische oder natürliche Kieselsäure, durch Kalziumkarbonat oder Polycarbonatpartikel gebildet sein. Die Größe der Partikel der Abstandshalter sollte etwa 3 bis 30 µm [≙ 10 -6 Meter], vorzugsweise zwischen 5 bis 15 µm [≙ 10 -6 Meter], betragen.The spacers may in this case be formed by an inorganic or organic antiblocking agent, for example synthetic or natural silica, by calcium carbonate or polycarbonate particles. The size of the particles of the spacers should be about 3 to 30 μm [≙ 10 -6 meters], preferably between 5 to 15 μm [≙ 10 -6 meters].
Bei Abstandshaltern aus synthetischer Kieselsäure ist es angezeigt, dass deren Anteil etwa 1000 bis 2000 ppm, bei Abstandshaltern aus natürlicher Kieselsäure deren Anteil etwa 2000 bis 5000 ppm und bei Abstandstandshaltern aus Kalziumkarbonat deren Anteil etwa 1000 bis 4000 ppm an der diese aufnehmenden Folie beträgt.For synthetic silica spacers, it is indicated that their content is about 1,000 to 2,000 ppm, for natural silica spacers about 2,000 to 5,000 ppm and for calcium carbonate spacers about 1,000 to 4,000 ppm of the receiving film.
Bei einer Ausrüstung der Innenseiten und/oder der Außenseiten der Beutel mit Abstandshaltern sollte der in die Innenseiten eingebundene Anteil in einer bevorzugten Ausgestaltung um mehr als 10 % größer bemessen sein als der in die Außenseiten eingebundene Anteil der Abstandshalter.With equipment of the insides and / or the outsides of the bags with spacers, the portion incorporated in the insides should, in a preferred embodiment, be more than 10% larger than the portion of the spacers incorporated in the outsides.
Es ist aber auch möglich, die Innenseiten und die an den Tragbändern haftende Außenseite der Folie mit unterschiedlichen Anteilen an Abstandshaltern, die Außenseite mit einem um vorzugsweise 10 bis 20 % größeren Anteil zu versehen.But it is also possible, the inner sides and adhering to the straps outer side of the film with different proportions of spacers to provide the outside with a preferably by 10 to 20% larger share.
Die Folie zur Herstellung der Beutel kann auch mehrschichtig extrudiert sein, wobei die Abstandhalter in die innere Schicht und/oder in die äußere Schicht der Folie einzubinden sind.The film for producing the bags can also be extruded in a multi-layered manner, wherein the spacers are to be integrated into the inner layer and / or into the outer layer of the film.
Vorteilhaft ist es des Weiteren, die Außen- und/oder Innenseiten der Beutel mit einem Gleitmittel zu versehen und bei Anordnung der Beutel an den Tragbändern den Abstand zwischen den Öffnungen der einzelnen Beutel mit höchstens 30 mm zu bemessen.It is furthermore advantageous to provide the outer and / or inner sides of the bags with a lubricant and, when the bags are arranged on the carrier tapes, to dimension the distance between the openings of the individual bags with at most 30 mm.
Die Beutel sollten mittels eines Haftklebstoffes an den vorzugsweise als Klebebändern ausgebildeten Tragbändern lösbar angebracht sein. Auch sollten die die Beutelkette bildenden Beutel zusammen mit den Tragbändern auf einem Rollenkern aufgewickelt sein.The bags should be releasably attached by means of a pressure-sensitive adhesive to the preferably designed as adhesive tapes tapes. Also, the bags forming the bag string should be wound together with the straps on a roll core.
Wird eine Beutelkette gemäß der Erfindung ausgebildet, in dem die Folie, aus der die Beutel hergestellt sind, mit eingebundenen Abstandshaltern und somit mit einem je nach Verwendungszweck nach Art und Konzentration wählbaren Antiblockmittel ausgerüstet werden, so ist zuverlässig die Gewähr gegeben, dass die Folien nicht aneinander haften und die Beutel zum Befüllen leicht zu öffnen sind. Durch die Abstandshalter wird nämlich gewährleistet, dass die Folien nicht aneinander anliegen, sondern dass zwischen diesen ein Luftspalt gebildet ist, aufgrund dessen die Folien auch bei hohen Arbeitsgeschwindigkeiten problemlos voneinander zu lösen sind.If a bag chain according to the invention is formed, in which the film from which the bags are made, equipped with integrated spacers and thus with a selectable depending on the purpose of type and concentration antiblocking agents, it is reliably guaranteed that the films are not stick together and the bags are easy to open for filling. By the spacers namely ensures that the films do not abut each other, but that an air gap is formed between them, due to which the films are easily solved even at high speeds from each other.
Die Ausrüstung der Innenseite der Beutel mit Antiblockmitteln bewirkt des Weiteren, dass beim Öffnen der Beutel insbesondere in der Anfangsphase des Öffnungsvorgangs das Nachströmen von Luft beim Auseinanderziehen des Beutels dadurch verbessert wird, dass durch die vom Antiblockmittel hervorgerufene Oberflächenrauhigkeit Kanülen und Kapillaren zur Verfügung stehen, durch die die Strömungsvorgänge in den Beutel sehr begünstigt werden. Auf diese Weise können der entstehende Unterdruck gemindert und die zum Öffnen erforderliche Kraft reduziert werden. Außerdem werden dadurch die Zuverlässigkeit des Öffnungsvorgangs und die Reproduzierbarkeit sowie die Betriebssicherheit der automatisierten Beutelverarbeitung verbessert, da sowohl dem vorzeitigen Abreißen von den Tragbändern als auch dem Verlieren durch Sauggreifer in der erst en Öffnungsphase entgegen gewirkt wird. Weiterhin bewirkt die Ausrüstung der Beutelaußenseite mit Antiblockmittel, dass durch die erhöhte Oberflächenrauhigkeit die effektive Klebefläche vergrößert und die Klebefestigkeit an den Tragbändern verbessert wird. Auch kann die Schuppung der Beutel verringert werden. Durch die sich auf diese Weise ergebenden Einsparungen an Tragbändern wird die Wirtschaftlichkeit gesteigert. Ferner erleichtert eine verbesserte Klebefestigkeit an den Tragbändern den Einsatz von Gleitmitteln, so dass die erforderlichen Gleiteigenschaften der Beutel gegeneinander durch eine geeignete Kombination von Antiblockmittel und Gleitmittel erzielt werden können.The equipment of the inside of the bag with anti-blocking agent also causes the opening of the bag, especially in the initial phase of the opening process, the flow of air when pulling the bag is improved by the fact that by the antiblocking caused surface roughness cannulas and capillaries are available through the flow processes in the bag are very favored. In this way, the resulting negative pressure can be reduced and the force required to open can be reduced. In addition, this improves the reliability of the opening process and the reproducibility and reliability of the automated bag processing, since both the premature tearing off of the straps and the loss is counteracted by suction pads in the first opening phase. Furthermore, the equipment of the bag exterior with anti-blocking agent causes the increased surface roughness effective adhesive surface increases and the adhesive strength is improved on the straps. Also, the scaling of the bags can be reduced. By resulting in this way savings on straps economic efficiency is increased. Furthermore, improved adhesive strength on the straps facilitates the use of lubricants, so that the required slip properties of the bags against each other can be achieved by a suitable combination of antiblocking agent and lubricant.
Durch die vorschlagsgemäße Ausgestaltung wird demnach eine Beutelkette geschaffen, deren Beutel ohne Schwierigkeiten auch bei hohen Arbeitsgeschwindigkeiten und mit geringen Kräften, insbesondere in der ersten Öffnungsphase zu öffnen sind, ohne dass die Beutel von den Tragbändern abreißen oder von den Sauggreifern verloren werden. Außerdem können die Tragbänder, da die spezifischen Klebekräfte an diesen höher als bisher gewählt werden können und somit die Beutel sehr dicht nebeneinander anzuordnen sind, verkürzt ausgebildet werden. Des Weiteren ist von Vorteil, dass bedingt durch die mit Abstand zueinander angeordneten Folien keine statische Aufladung entsteht und dass keine zusätzlichen Hilfsmittel zum Öffnen der Beutel erforderlich sind. Eine vielseitige Verwendbarkeit der Beutelkette ist demnach gegeben.By virtue of the proposed embodiment, a bag chain is thus created, the bags of which can be opened without difficulty even at high operating speeds and with low forces, in particular in the first opening phase, without the bags being torn off the carrier tapes or being lost by the suction grippers. In addition, since the specific adhesive forces on these can be selected to be higher than hitherto, and thus the bags are to be arranged very close to each other, the carrier tapes can be made shorter. Furthermore, it is advantageous that due to the spaced-apart foils no static charge is created and that no additional tools for opening the bag are required. A versatility of the bag chain is therefore given.
