Description
Die Erfindung betrifft eine Vorrichtung zum Zuführen von Folienbeuteln zu einer Füllmaschine gemäß dem Oberbegriff des Anspruchs 1 und ein entsprechendes Verfahren gemäß Anspruch 11.The invention relates to a device for feeding foil bags to a filling machine according to the preamble of
Es ist bekannt, Folienbeutel, die in Magazinschächten eines Magazins bereitgestellt werden, in die Magazinschächte fallen zu lassen, so dass sie durch die Schwerkraft nach unten gezogen werden. Dadurch gelangen die Folienbeutel in unterhalb der Magazinschächte angeordnete Folienbeutelaufnahmen zum Aufnehmen und Weitertransportieren der Folienbeutel. Durch die Verwendung der Schwerkraft für das nach unten Bewegen der Folienbeutel ist nicht immer eine passende Ausrichtung der Folienbeutel in Bezug zu den Folienbeutelaufnahmen gewährleistet, da sich Folienbeutel in einem Magazinschacht drehen oder verkanten können. Auch die Maschinengeschwindigkeit ist begrenzt.It is known to let foil bags, which are provided in magazine shafts of a magazine, fall into the magazine shafts so that they are pulled down by gravity. As a result, the foil bags reach into foil bag receptacles arranged beneath the magazine shafts for picking up and further transporting the foil bags. The use of gravity to move the film bags down does not always ensure proper alignment of the film bags relative to the film bag receivers since film bags can rotate or tilt in a magazine slot. The machine speed is limited.
Die Aufgabe der Erfindung besteht darin, eine Vorrichtung und ein Verfahren zum Zuführen von Folienbeuteln zu einer Füllmaschine zur Verfügung zu stellen, die eine störungsfreie, definierte Übergabe von in Magazinschächten bereitgestellten Folienbeuteln an Folienbeutelaufnahmen auch mit einer hohen Maschinengeschwindigkeit ermöglichen.The object of the invention is to provide an apparatus and a method for feeding foil bags to a filling machine, which enable a trouble-free, defined transfer of foil bags provided in magazine shafts to foil bag receptacles, even at a high machine speed.
Die Aufgabe wird gelöst durch die Vorrichtung nach Anspruch 1 und das Verfahren nach Anspruch 11. Bevorzugte Ausführungsformen und Weiterbildungen sind in den Unteransprüchen offenbart.The object is achieved by the device according to
Die Vorrichtung zum Zuführen von Folienbeuteln zu einer Füllmaschine umfasst ein Magazin mit mehreren, parallel angeordneten Magazinschächten zum Bereitstellen der Folienbeutel und unterhalb der Magazinschächte positionierbare Folienbeutelaufnahmen zum Aufnehmen und zum Weitertransportieren der aufgenommenen Folienbeutel. Weiter ist jedem Magazinschacht ein Übergabearm zum Ergreifen eines Folienbeutels in dem Magazinschacht und zum Übergeben des ergriffenen Folienbeutels an die unterhalb des Magazinschachts angeordnete Folienbeutelaufnahme zugeordnet.The device for feeding foil bags to a filling machine comprises a magazine having a plurality of magazine shafts arranged in parallel for providing the foil bags and foil bag receivers positionable below the magazine shafts for receiving and transporting the accommodated foil bags. Further, each magazine shaft is assigned a transfer arm for gripping a film bag in the magazine shaft and for transferring the gripped film bag to the film bag receptacle arranged below the magazine shaft.
Durch die Verwendung der Übergabearme ist eine gezielte Übergabe der Folienbeutel an die Folienbeutelaufnahmen möglich, wodurch eine Verdrehung oder Verkantung von Folienbeuteln in den Magazinschächten vermieden werden kann. Somit kann die Vorrichtung auch mit einer hohen Maschinengeschwindigkeit betrieben werden, wobei immer eine gezielte Übergabe der Folienbeutel an die Folienbeutelaufnahmen erfolgt. Das Ergreifen und Übergeben der Folienbeutel mit den Übergabearmen kann als eine Zwangsführung angesehen werden, da dabei zufällige, nicht erwünschte Bewegungen der Folienbeutel unterbunden werden.By using the transfer arms, a targeted transfer of the foil bag to the foil bag receptacles is possible, whereby a twisting or tilting of foil bags can be avoided in the magazine shafts. Thus, the device can also be operated at a high machine speed, whereby a targeted transfer of the foil bag always takes place on the foil bag receptacles. The gripping and transfer of the foil bag with the transfer arms can be regarded as a forced operation, as this random, unwanted movements of the foil bags are prevented.
Die Übergabearme können jeweils mindestens eine Saugvorrichtung zum Ansaugen der Folienbeutel umfassen. Die Saugvorrichtungen ermöglichen ein schonendes Ergreifen der Folienbeutel sowie einen sicheren Transport von den Magazinschächten zu den Folienbeutelaufnahmen. Die Saugvorrichtungen können mit einem oder mehreren Vorrichtungen zum Erzeugen eines Unterdrucks ausgestattet sein. Beispielsweise umfasst ein Übergabearm zwei Saugvorrichtungen mit einem kreisförmigen oder zumindest näherungsweise kreisförmigen Querschnitt, die an einem Folienbeutel symmetrisch angreifen.The transfer arms may each comprise at least one suction device for sucking the film bag. The suction devices enable a gentle gripping of the foil bags as well as a safe transport from the magazine shafts to the foil bag holders. The suction devices may be equipped with one or more negative pressure generating devices. For example, a transfer arm comprises two suction devices with a circular or at least approximately circular cross-section which engage symmetrically on a foil bag.
Jede der Saugvorrichtungen kann dazu ausgelegt sein, einen Folienbeutel zumindest teilweise flächig anzusaugen. Für das Ergreifen und Übergeben der Folienbeutel an die Folienbeutelaufnahmen ist es ausreichend, wenn die Saugvorrichtungen den Folienbeutel nicht komplett ansaugen, sondern nur eine Teilfläche des jeweiligen Folienbeutels angesaugt wird. Durch das nur teilweise flächige Ansaugen ist auch ein nachfolgendes Lösen der Saugvorrichtung vom Folienbeutel einfacher.Each of the suction devices can be designed to suck a film bag at least partially flat. For gripping and transferring the film bag to the film bag receptacles, it is sufficient if the suction devices do not completely suck the film bag, but only a partial surface of the respective film bag is sucked. By only partially flat suction and a subsequent release of the suction device from the foil bag is easier.
Die Übergabearme können um eine gemeinsame horizontale Achse drehbar und mittels eines gemeinsamen Gestänges vertikal verfahrbar ausgelegt sein. Durch die Drehbarkeit der Übergabearme ist es möglich, dass die Folienbeutel in den Magazinschächten ergriffen werden und dann im Magazinschacht in eine Ausrichtung verbracht werden, aus der sie durch ein vertikales Verfahren des Gestänges zumindest teilweise aus dem Magazinschacht entfernt und zumindest teilweise in die Folienbeutelaufnahmen eingebracht werden können. Als Antrieb für das Gestänge zum vertikalen, d.h. nach oben und nach unten, Verfahren kann im oberen Bereich des Gestänges eine Zahnstange mit Antriebsrädern vorgesehen sein.The transfer arms can be designed to be rotatable about a common horizontal axis and to be vertically movable by means of a common linkage. Due to the rotatability of the transfer arms, it is possible for the film bags to be grasped in the magazine shafts and then brought into alignment in the magazine shaft, from which they are at least partially removed from the magazine shaft by a vertical movement of the linkage and at least partially introduced into the film bag receptacles can. As a drive for the linkage to the vertical, i. up and down, method may be provided in the upper region of the linkage a rack with drive wheels.
Zwischen zwei benachbarten Magazinschächten kann eine Schiebevorrichtung angeordnet sein, die mindestens einen Schieber umfasst, der vorzugsweise vertikal verfahrbar ist. Mittels des Schiebers können Folienbeutel innerhalb der Folienbeutelaufnahmen in gewisser Weise an ihrem Platz gehalten werden, ohne dass eine unerwünschte Bewegung nach oben erfolgt, z.B. wenn ein Übergabearm von einem Folienbeutel gelöst bzw. dann nach oben verfahren wird.Between two adjacent magazine shafts, a sliding device may be arranged, which comprises at least one slide, which is preferably movable vertically. By means of the slider, foil pouches within the foil pouches can be held in place to some extent without undesirable upward movement, e.g. when a transfer arm is released from a foil bag or then moved upwards.
Die Schiebevorrichtung kann derart zwischen zwei benachbarten Magazinschächten angeordnet, dass der erste der beiden Schieber jeweils auf Folienbeutel des einen Magazinschachts und der zweite der beiden Schieber jeweils auf Folienbeutel des anderen Magazinschachts einwirken kann. Im Allgemeinen erfolgt eine Einwirkung der Schieber auf einen Folienbeutel daher in den rechten und linken oberen Randbereichen des Folienbeutels.The sliding device can be arranged between two adjacent magazine shafts such that the first of the two slides each on foil bag of a magazine shaft and the second of the two slides can each act on foil bags of the other magazine shaft. In general, an action of the slider on a film bag therefore takes place in the right and left upper edge regions of the film bag.
Ein Übergabespalt kann zwischen dem mindesten einen Schieber und einem Grundkörper des Magazins ausbildbar sein. Der Übergabespalt wird ausgebildet, wenn der mindestens eine Schieber nach unten verfahren ist, wodurch die gezielte Übergabe der Folienbeutel an die Folienbeutelaufnahmen unterstützt werden kann, da eine unerwünschte Bewegung der Folienbeutel unterbunden wird. Die Breite des Übergabespalts ist hierbei vorzugsweise kleiner als 1 mm, jedoch kann diese Breite an den Typ des Folienbeutels angepasst werden.A transfer gap can be formed between the at least one slide and a main body of the magazine. The transfer gap is formed when the at least one slide is moved down, whereby the targeted transfer of the foil bag can be supported on the foil bag receptacles, since unwanted movement of the foil bag is prevented. The width of the transfer gap is preferably less than 1 mm, but this width can be adapted to the type of film bag.
Der mindestens eine Schieber kann eine Labyrinthführung zum Unterbinden einer nach oben Bewegung eines Folienbeutels umfassen. Die Labyrinthführung ist dafür vorgesehen, eine Aufwärtsbewegung eines Folienbeutels zu vermeiden, beispielsweise wenn ein Übergabearm nach dem Lösen von dem Folienbeutel bewegt wird. Beispielsweise kann die Labyrinthführung als ein Vorsprung ausgebildet sein. Da sich die Labyrinthführung bei nach unten gefahrenem Schieber zumindest teilweise in dem Transportweg des von dem Übergabearm ergriffenen und bewegten Folienbeutel befindet, wird beim nach unten Bewegen des Folienbeutels dieser entsprechend bei Kontakt mit der Labyrinthführung in seinen rechten und linken Randbereichen gebogen.The at least one slider may include a labyrinth guide for inhibiting upward movement of a foil bag. The labyrinth guide is intended to prevent upward movement of a foil bag, for example when a transfer arm is moved after release from the foil bag. For example, the labyrinth guide may be formed as a projection. Since the labyrinth guide is at least partially in the transport path of grasped by the transfer arm and moving foil pouch when moving down slide the bag is bent when moving the plastic bag in accordance with this in contact with the labyrinth in its right and left margins.
Die Schiebevorrichtung kann ein Gehäuse umfassen, das den mindestens einen Schieber aufnehmen kann.The pusher may include a housing that can receive the at least one slider.
Die Vorrichtung kann weiter mindestens einen Gegenhalter umfassen, der horizontal verfahrbar ausgelegt ist zum Unterbinden einer nach oben Bewegung eines Folienbeutels. Während ein Folienbeutel durch einen Übergabearm ergriffen und zumindest teilweise in einen Folienbeutelaufnahme eingebracht wird, befindet sich der mindestens eine Gegenhalter vorzugsweise in einer ersten Position außerhalb des Bewegungswegs von Übergabearm und/oder Folienbeutel. Nachdem der Folienbeutel zumindest teilweise in die Folienbeutelaufnahme eingebracht wurde, kann der mindestens eine Gegenhalter horizontal aus der ersten Position in eine zweite Position verfahren werden, so dass der mindestens einen Gegenhalter derart oberhalb des Folienbeutels positioniert ist, dass er ein unerwünschtes nach oben Bewegen des Folienbeutels unterbinden kann, z.B. wenn ein Übergabearm von einem Folienbeutel gelöst bzw. dann nach oben verfahren wird.The device may further comprise at least one counter-holder, which is designed to be horizontally movable to prevent upward movement of a film bag. While a foil bag is gripped by a transfer arm and at least partially inserted into a foil bag receptacle, the at least one counterholder is preferably in a first position outside the path of movement of the transfer arm and / or foil bag. After the film bag has been at least partially introduced into the film bag receptacle, the at least one counter holder can be moved horizontally from the first position to a second position, so that the at least one counter holder is positioned above the film bag such that it undesirably moves upward the film bag can prevent, for example when a transfer arm is released from a foil bag or then moved upwards.
Die Folienbeutelaufnahmen können als Klammer-/Schließkästen ausgebildet sein.The foil bag receptacles can be designed as staple / lock boxes.
Das Verfahren zum Zuführen von Folienbeuteln zu einer Füllmaschine mit einer Vorrichtung wie oben oder weiter unten beschrieben umfasst die Schritte: Bereitstellen von Folienbeuteln in Magazinschächten eines Magazins, Positionieren von Folienbeutelaufnahmen zum Aufnehmen und Transportieren der Folienbeutel unterhalb der Magazinschächte, dann Ergreifen der Folienbeutel in den Magazinschächten mittels Übergabearmen und Übergeben der ergriffenen Folienbeutel an die Folienbeutelaufnahmen mittels der Übergabearme.The method of feeding foil bags to a filling machine with a device as described above or below comprises the steps of providing foil bags in magazine shafts of a magazine, positioning of foil bag receptacles for receiving and transporting the foil bag below the magazine shafts, then gripping the foil bag in the magazine shafts by means of transfer arms and transferring the seized foil bag to the foil bag receptacles by means of the transfer arms.
In jedem der Magazinschächte kann eine bestimmte Anzahl von Folienbeuteln bereitgestellt werden und bevor diese Anzahl von Folienbeuteln verwendet wurde, können weitere Folienbeutel nachgefüllt werden. Da die Folienbeutel von dem Magazin zu einer Füllmaschine verbracht werden sollen, werden unterhalb des Magazins Folienbeutelaufnahmen bereitgestellt. Dabei werden bei einer Anzahl n von parallel angeordneten Magazinschächten n Folienbeutelaufnahmen bereitgestellt, wobei jeweils eine Folienbeutelaufnahme unterhalb eines Magazinschachts positioniert wird. Somit kann ein Folienbeutel eines Magazinschachts an eine Folienbeutelaufnahme übergeben und durch sie dann transportiert werden. Durch das Ergreifen eines Folienbeutels in einem Magazinschacht kann eine geführte Bewegung des Folienbeutels erfolgen, so dass er in einer definierten Weise an die Folienbeutelaufnahme übergeben werden kann.In each of the magazine shafts, a certain number of foil bags can be provided and before this number of foil bags is used, more foil bags can be refilled. Since the film bags are to be moved from the magazine to a filling machine, foil bag receptacles are provided below the magazine. In this case, n foil bag receptacles are provided with a number n of magazine shafts arranged in parallel, wherein in each case a foil bag receptacle is positioned below a magazine shaft. Thus, a foil bag of a magazine shaft can be transferred to a foil bag receptacle and then transported through it. By gripping a foil bag in a magazine shaft, a guided movement of the foil bag can take place, so that it can be transferred to the foil bag receptacle in a defined manner.
Der Schritt des Ergreifens kann ein Ansaugen der Folienbeutel mittels Saugvorrichtungen umfassen, wobei ein Folienbeutel beispielsweise zumindest teilweise flächig angesaugt wird. Durch das nur teilweise flächige Ansaugen ist auch ein nachfolgendes Lösen der Saugvorrichtung vom Folienbeutel einfacher. Die Saugvorrichtungen können ein schonendes Ergreifen der Folienbeutel sowie einen sicheren Transport von den Magazinschächten zu den Folienbeutelaufnahmen ermöglichen. Das Ansaugen kann durch Ausbilden eines Unterdrucks erfolgen.The step of grasping may include suction of the foil pouches by means of suction devices, wherein a foil pouch is sucked, for example, at least partially flat. By only partially flat suction and a subsequent release of the suction device from the foil bag is easier. The suction devices can enable a gentle gripping of the foil bags as well as a safe transport from the magazine shafts to the foil bag receptacles. The suction can be done by forming a negative pressure.
Der Schritt des Übergebens kann weiter den folgenden Schritt umfassen: Drehen der Übergabearme um eine gemeinsame horizontale Achse und dadurch ein Verbringen der Folienbeutel in eine zumindest näherungsweise vertikale Ausrichtung. Aus dieser Ausrichtung heraus können die Folienbeutel an die Folienbeutelaufnahmen übergeben werden. Durch das Drehen um die horizontale Achse können die Übergabearme derart bewegt werden, dass sie die Folienbeutel vom Ort ihres Ergreifens in einem Magazinschacht zumindest teilweise aus dem Magazinschacht heraus bewegen.The handover step may further comprise the step of rotating the transfer arms about a common horizontal axis and thereby moving the foil bags into an at least approximately vertical orientation. From this orientation, the foil bags can be passed to the foil bag receptacles. By rotating about the horizontal axis, the transfer arms can be moved to at least partially move the foil pouches out of the magazine slot from the location of their capture in a magazine slot.
Nach dem Schritt des Ergreifens und vor dem Schritt des Drehens kann ein Ausfahren der Schieber erfolgen. Die ausgefahrenen Schieber sorgen im Weiteren dafür, dass in die Folienbeutelaufnahmen eingebrachte Folienbeutel beim Lösen der Übergabearme von den Folienbeuteln und beim nach oben Verfahren der gelösten Übergabearme keine unerwünschte Bewegung nach oben ausführen.After the step of grasping and before the step of turning, the slides can be extended. Furthermore, the extended slides ensure that foil bags introduced into the foil bag holders do not make any undesired upward movement when releasing the transfer arms from the foil bags and during the upward movement of the dissolved transfer arms.
Nach dem Drehen können weiter die folgenden Schritte erfolgen: nach unten Verfahren der Übergabearme und zumindest teilweises Einbringen der Folienbeutel in die Folienbeutelaufnahmen und nach dem Einbringen Lösen der Saugvorrichtungen von den Folienbeuteln. Bei dem nach unten Verfahren der Übergabearme werden die Folienbeutel auch an den ausgefahrenen Schiebern und deren Labyrinthführung vorbeibewegt. Dabei kommen die Folienbeutel jeweils in Kontakt mit den Labyrinthführungen, so dass ein Folienbeutel in seinen rechten und linken Randbereichen gebogen wird. Wenn ein Folienbeutel in eine Folienbeutelaufnahme eingebracht ist, bei einem Klammer-/Schließkasten beispielsweise auf dessen Kastengrund aufsteht, verhindern die Schieber und die Labyrinthführungen, dass der Folienbeutel eine Bewegung nach oben ausführen kann. Daher kann dann die Saugvorrichtung von dem Folienbeutel gelöst und der Saugarm nach oben verfahren werden.After turning, the following steps may further be carried out: downwards movement of the transfer arms and at least partial introduction of the film bags into the film bag receptacles and after insertion release of the suction devices from the film bags. In the down process of the transfer arms, the foil bags are also moved past the extended slides and their labyrinth guide. In this case, the foil bags each come in contact with the labyrinth guides, so that a foil bag is bent in its right and left edge areas. When a foil bag is inserted into a foil bag receptacle, for example, stands up on its box base in a stapling / closing box, the slides and the labyrinth guides prevent the foil bag from moving upwards. Therefore, the suction device can then be released from the foil bag and the suction arm can be moved upwards.
Nach dem Schritt des Lösens kann ein nach oben Verfahren der Übergabearme erfolgen. Vorzugsweise erfolgt auch ein Drehen der Übergabearme, so dass sich die Übergabearme dann in einer Position in der sie erneut Folienbeutel ergreifen können.After the disengagement step, an upward process of the transfer arms may be performed. Preferably, a rotation of the transfer arms, so that the transfer arms then in a position in which they can again take foil bag.
Nach dem nach oben Verfahren der Übergabearme kann ein nach oben Verfahren der Schieber erfolgen. Nach dem nach oben Verfahren der Schieber kann ein Verfahren der Folienbeutelaufnahmen aus ihrer Position unterhalb der Magazinschächte erfolgen. Die Folienbeutelaufnahmen können dann die Folienbeutel einer Füllmaschine zuführen.After the upward procedure of the transfer arms, an upward procedure of the slide can be done. According to the upward method of the slide, a method of film bag receptacles can be made from their position below the magazine shafts. The foil bag holders can then feed the foil bags to a filling machine.
