Description

Vorrichtung zum automatischen Anhängen von Säcken Device for automatically hanging bags
Die Erfindung betrifft ein Verfahren zum automatischen Anhängen von Säcken gemäss dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung hierzu. Diese betrifft insbesondere das Ergreifen und Öffnen von offenen Säcken, vorzugsweise solchen auε gewobe¬ nen, luftdurchlässigen Materialien, um diese an einen Sackstut- zen anzuhängen und nachfolgend zu füllen.The invention relates to a method for automatically attaching bags according to the preamble of claim 1 and an apparatus therefor. This relates in particular to the gripping and opening of open sacks, preferably those made from air-permeable materials, in order to hang them on a sack support and then fill them.
Es ist an sich bekannt, Säcke automatisch zu greifen und zu öffnen, um diese nachfolgend ebenso automatisch an einen Sack- stutzen anzuhängen und zu füllen. So beschreibt die EP-B-293615 eine Vorrichtung zum Füllen und Verschliessen von Papier-Sei- tenfaltensäcken. Hierbei werden einzelne Säcke von Saugern aus einem Paket entnommen und zwischen Saugleisten gefahren. Diese Saugleisten werden nachfolgend bis zu einem Anschlag auseinan¬ der gefahren. Mittels der Saugleisten wird der Sack soweit ge- öffnet, dass schwenkbare Aussengreifer die ausseren Falten ge¬ gen Gegenhalter drücken können.It is known per se to automatically grip and open sacks in order to subsequently also automatically attach and fill them on a sack nozzle. For example, EP-B-293615 describes a device for filling and closing paper gusseted bags. Here, individual bags of suction cups are removed from a package and moved between suction strips. These suction strips are then moved apart as far as they will go. By means of the suction strips, the sack is opened to such an extent that swiveling external grippers can press the outer folds against the counter-holder.
Der vorgeöffnete Sack wird anschliessend mittels eines Schlit¬ tens in eine Füllstation unter einen ortsfesten Fülltrichter bewegt und dann von schwenkbaren Greifern ergriffen. Während des Füllvorganges kann der Schlitten zurückfahren, um einen neuen Sack aufzunehmen.The pre-opened sack is then moved by means of a slide into a filling station under a stationary filling funnel and then gripped by swiveling grippers. During the filling process, the carriage can move back to pick up a new bag.
Eine ähnliche Lösung für eine automatische Sackanhängung be- schreibt die EP-A-522110. Wiederum mit Sauggreifern wird einA similar solution for an automatic bag attachment is described in EP-A-522110. Again with suction cups is a
Sack vom Stapel entnommen, vorgeöffnet, von Sacköffnungsklauen erfasst, geöffnet und gleichzeitig über ein Doppelhebelεystem zu einem Absackstutzen geführt und automatisch festgeklemmt. Der zu öffnende Sack wird faktisch wie "über's Knie gezogen", um ein geeignetes Verformen und Voröffnen des Sackes zu errei¬ chen. Derartige Lösungen mit Sauggreifern εind nur für Säcke aus luftundurchlässigen Materialien geeignet. Sie erfordern zudem einen zusätzlichen Energieaufwand.Sack removed from the stack, pre-opened, gripped by sack opening claws, opened and at the same time guided to a sack nozzle by a double lever system and automatically clamped. The sack to be opened is actually pulled over the knee in order to achieve a suitable deformation and opening of the sack. Such solutions with suction pads are only suitable for bags made of air-impermeable materials. They also require additional energy expenditure.
Mechanische Greifer für derartige Handhabungsoperationen sind technisch kompliziert und störanfällig sowie teuer.Mechanical grippers for such handling operations are technically complicated and prone to failure as well as expensive.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum automatischen Anhängen von Säcken zu schaffen, die es gestattet, Säcke aus verschiedenen Materialien mit einfachen Mitteln und funktionssicher zu greifen und zu öffnen, um sie an einen Sackstutzen anzuhängen.The invention is therefore based on the object of providing a method and a device for automatically attaching sacks, which allows sacks of various materials to be gripped and opened with simple means and in a functionally reliable manner in order to attach them to a sack spout.
Diese Aufgabe wird mit den Merkmalen des Kennzeichens des An- spruchs gelöst.This problem is solved with the features of the characterizing part of the claim.
Die Erfindung geht hierbei von an εich bekannten Möglichkeiten zur Schaffung adhäsiver Verbindungen aus, wobei solche Mittel anstelle von Sauggreifern u. dgl. zur Anwendung kommen. Zum Greifen und Öffnen von, insbesondere luftdurchlässigen und of¬ fenen, leeren Säcken werden zwischen Sack und Greifelement tem¬ porär adhäsive Verbindungen hergestellt. Dies gestattet eε, die Greifelemente nach dem Anhängen und Klemmen des geöffneten Sak- kes am Sackεtutzen problemlos vom Sackmaterial zu lösen, wobei durch die Wahl geeigneter Abzugsbewegungen bzw. -geschwindig- keiten Beschädigungen des Sackmaterialeε kaum oder nicht auf¬ treten.The invention is based on known εich ways to create adhesive connections, such means instead of suction pads u. Like. Are used. Temporary adhesive connections are made between the bag and the gripping element for gripping and opening, in particular air-permeable and open, empty sacks. This allows the gripping elements to be detached from the sack material without any problems after the open sack has been attached and clamped on the sack spout, with the sack material being scarcely or not at all damaged by the choice of suitable pulling movements or speeds.
Besonders geeignet sind werkzeugseitig selbεt erneuernde Haftstellen, wie Heisεkleber, Klebeεticks und Rollenkleber u. dgl. sowie ggf. auch Klettbänder.Particularly suitable on the tool side are self-renewing traps such as hot glue, glue sticks and roller glue and the like. Like. And possibly also Velcro.
Für daε Auftragen von Leim bzw. Klebstoff sind mehrere Varian¬ ten anwendbar, sowohl was das Auftragen selbst, alε auch daε Abreiεεen der Greifeinrichtung vom Klebεtoff bzw. Sackmaterial anbelangt . Sackmaterialien sind neben Papier und Plastfolien vor allem auch gewobene Kunststoffe, Baumwoll- und Jutegewebe u. a.For the application of glue or adhesive, several variants can be used, both with regard to the application itself and also with regard to tearing off the gripping device from the adhesive or sack material. In addition to paper and plastic films, sack materials are primarily woven plastics, cotton and jute fabrics, among others
Der Vorteil der erfindungsgemassen Lösung besteht vor allem darin, dasε, im Gegensatz zu Sauggreifern verschiedenste und auch gewobene luftdurchlässige Sackmaterialien gehandhabt wer¬ den können und die Greifelemente selbεt einfacher geεtaltet werden können. Inεbeεondere entfällt eine Pneumatik.The advantage of the solution according to the invention is above all that, in contrast to suction pads, a wide variety of and also woven air-permeable sack materials can be handled and the gripping elements themselves can be designed more easily. In particular, pneumatics are omitted.
Eε εind hierbei verεchiedene an εich bekannte Varianten des Aufnehmenε und Lagefixierenε von Säcken von einem Stapel bzw. Magazin denkbar, z.B. gemäεε DE-A-4116311 , EP-A-522110 oder WO 95/09765.Various variants of picking up and fixing the sacks of a stack or magazine, which are known per se, are conceivable, e.g. according to DE-A-4116311, EP-A-522110 or WO 95/09765.
Die erfindungεgemäεεe Löεung wird nachfolgend in einem Ausfuh¬ rungsbeispiel an Hand einer Zeichnung näher beschrieben.The solution according to the invention is described in more detail below in an exemplary embodiment with the aid of a drawing.

Fig. 1 eine Prinziplösung der erfindungsgemassen Lösung Fig. 2 eine mögliche Ausführungsform von Teilen der Greifeinrichtung.Fig. 1 shows a principle solution of the inventive solution Fig. 2 shows a possible embodiment of parts of the gripping device.
Die Vorrichtung zum automatischen Anhängen von Säcken besteht auε einer Greifeinrichtung 1 mit Greifzapfen 2. Die Greifein¬ richtung 1 kann je nach Bereitstellungspoεition der leeren Säcke 3 eine beliebige Anhängebewegung an einen Sackεtutzen 4 mittelε an sich bekannter Handhabungselemente ausführen, wie dies z. B. in der EP-A-522110 beschrieben ist. In ebenso be- kannter Weise ist der Sackstutzen 4 mit Sackklemmen 5 verεehen.The device for automatically attaching sacks consists of a gripping device 1 with a gripping pin 2. Depending on the position of the empty sacks 3, the gripping device 1 can carry out any appending movement on a sack nozzle 4 by means of handling elements known per se. B. is described in EP-A-522110. In a known manner, the sack nozzle 4 is provided with sack clamps 5.
Durch leichte Bauweise iεt ein hohes Leiεtungsvermögen gegeben.Due to the light construction, a high performance is given.
Die Greifzapfen 2 εind mit selbstemeuemden Haftstellen 6 be- stückt. Dies εind im konkreten Fall Hotmelt-Punkte mit nur ge¬ ringerer Haftung an den Greifzapfen 2 als am Material deε Sak- In Funktion ist die erfindungsgemässe Vorrichtung wie folgt be¬ schreibbar:The gripping pins 2 ε are equipped with self-sealing adhesive points 6. In the specific case, these are hot-melt points with only less adhesion to the gripping pins 2 than to the material of the sack. In operation, the device according to the invention can be described as follows:
Ein leerer Sack 3 wird mittelε eines Paares von Greifzapfen 2 einem nicht im Detail dargestellten Magazin in liegender Posi¬ tion entnommen. Beide Greifzapfen sind mit Hotmelt-Punkten alε Haftstellen 6 versehen. Beim Greifen des Sackes 3 klebt das Sackmaterial an den Haftstellen 6 an und durch einfaches Aus¬ einanderfahren der Greifzapfen 2 wird der Sack 3 soweit geöff- net, daεε er nach entεprechender Bewegung unter den Sackstutzen 4 an dieεen angehangen und mittels Sackklemmen 5 befeεtigt wird. Vorzugεweise steht hierbei der Sack 3 mit seinem Boden auf einem Transportband o. dgl.An empty sack 3 is removed in a lying position by means of a pair of gripping pins 2 from a magazine (not shown in detail). Both gripping pins are provided with hot-melt points as detent points 6. When the sack 3 is gripped, the sack material sticks to the adhesion points 6 and by simply moving the gripping pins 2 apart, the sack 3 is opened to such an extent that, after a corresponding movement, it is attached to the sack nozzle 4 and fastened by means of sack clamps 5. The sack 3 is preferably standing with its bottom on a conveyor belt or the like.
Diese Greifzapfen 2 können sowohl gleichzeitig als auch nach¬ einander zum Erfassen und Öffnen des Sackes 3 an dieεem angrei¬ fen.These gripping pins 2 can act on the latter both simultaneously and in succession to grasp and open the sack 3.
Nach dem Klemmen deε Sackes 3 am Sackstutzen 4 reisεen die Hot- melt-Punkte durch Öffnen der Greifzapfen 2 von dieεen ab und verbleiben am Sackmaterial. Der Sack 3 wird anschlieεεend in üblicher Weise gefüllt und nachfolgend verschlossen. Ebenso schadlos wäre auch ein Abreiεεen der Hotmelt-Punkte vom Sackma¬ terial, jedoch müεεten in diesem Fall die Haftstellen 6 der Greifzapfen jeweils gereinigt werden.After the sack 3 has been clamped to the sack spout 4, the hot-melt points tear away from them by opening the gripping pins 2 and remain on the sack material. The bag 3 is then filled in the usual way and then closed. It would also be harmless to tear off the hot-melt points from the sack material, but in this case the grip points 6 of the gripping pins would have to be cleaned in each case.
Die Hotmelt-Punkte werden alε εelbεterneuernde Haftstellen 6 mittels üblicher Auftragεeinrichtungen (z. B. Düεenauftrag) vor dem Greifen eineε Sackes 3 aufgebracht oder εie εind innerhalb der Greifzapfen 2 in einer Vorεchub- und Erwärτnungεeinrichtung angeordnet. Der Greifzapfen 2 kann ggf. auch eine Kühlung bein¬ halten, um ein εchnelleε Abkühlen der Hotmelt-Punkte zu errei¬ chen.The hot-melt points are applied as self-renewing adhesive spots 6 by means of conventional application devices (e.g. nozzle application) before gripping a sack 3 or are arranged inside the gripping pins 2 in a feed and heating device. The gripping pin 2 can optionally also include cooling in order to achieve a rapid cooling of the hot melt points.
Nach einer anderen Variante kann der Greifzapfen 2 aus einem reverεierbaren Haftstempel 21, der in einer, ebenfalls rever- εierbaren Abdrückhülse 22 geführt ist, beεtehen. Der Klebpunkt für die Haftstelle 6 wird mittels einer Düse 23 aufgetragen, wobei eine schnelle Abkühlung gegeben ist. Ebenfalls möglich ist es, den Klebstoff über eine Bohrung im Haftstempel 21 zuzu¬ führen, was betriebsεicherer aber techniεch aufwendiger iεt. Der Haftstempel 21 haftet, wie beschrieben, über die Haftstelle 6 am Sack 1 und kann mittels der reversierbaren Abdrückhülεe 22 vom Sack 1 getrennt werden.According to another variant, the gripping pin 2 can consist of a reversible adhesive stamp 21, which is guided in a, also reversible, push-off sleeve 22. The adhesive point for the adhesion point 6 is applied by means of a nozzle 23, with rapid cooling. It is also possible to feed the adhesive through a hole in the adhesive stamp 21, which is more reliable but technically more complex. As described, the adhesive stamp 21 adheres to the bag 1 via the adhesive point 6 and can be separated from the bag 1 by means of the reversible push-off sleeve 22.
In einer weiteren Variante könnten die Greifzapfen 2 auch am geklemmten Sack 3 verbleiben, um den gefüllten Sack 3 nach dem Löεen vom Sackstutzen 4 auf einem Transportband in eine Ver- schliessstation zu führen.In a further variant, the gripping pins 2 could also remain on the clamped sack 3 in order to guide the filled sack 3 after it has been released from the sack spout 4 on a conveyor belt into a closing station.
Weitere Varianten zur Auεführung der Haftstellen 6 εind vor¬ schubgesteuerte Klebestickε oder Klebrollen oder auch an εich bekannte Klettbänder. Letztere neigen jedoch zur Verεchmutzung und sind nicht für alle Materialien anwendbar.Further variants for the execution of the adhesion points 6 are feed-controlled adhesive sticks or adhesive rolls or also on Velcro strips which are known per se. However, the latter tend to become dirty and cannot be used for all materials.
In verschiedenen, an sich bekannten Möglichkeiten kann hierbei der Sack 3 oder der geεamte Sackstapel 7 in seiner Lage fixiert werden, um ein sicheres Vereinzeln, Öffnen und Bewegen des Sak- keε l zu erreichen. Dieε kann über einen Gegenhalter zu einem oberen Greifzapfen 2' erfolgen, oder auch mittelε eineε Fixie- renε deε Sackstapels εeitlich vor der Abnahmeεtelle 8. Tech¬ niεch kann dieε mittelε eineε abklappbaren Niederhalters erfol- gen. In various ways known per se, the sack 3 or the entire sack stack 7 can be fixed in its position in order to achieve a safe separation, opening and movement of the sack 1. This can be done by means of a counterholder to an upper gripping pin 2 ', or also by means of fixing the sack stack laterally in front of the removal point 8. Technically, this can be done by means of a fold-down holder.
