Abstract

The bottom opening station (1) contains a bottom opening cylinder (2) with gripper tool (5), which takes the paper bag part and twists it in the same direction as the cylinder's turning axis. The necessary force to grasp the paper bag part and to turn it around the cylinder originates from one ready source of energy. A second energy source is on hand to power the gripper tool which works in opposition to the first energy source and opens the gripper. The first energy source can come from a spring, magnet or other device while the second comes from the curved packaging - once the length of the packaging has been passed the force holding it against the cylinder ceases and the gripper opens.

Description

Die Erfindung betrifft eine Bodenöffnungsstation einer Papierbeutelmaschine nach dem Oberbegriff des Anspruchs 1.
Papierbeutelmaschinen sind seit langem bekannt. Beispielsweise zeigt die DE 197 02 144 A1 Elemente solcher Vorrichtungen. Die Patentschrift DE 1 080 846 zeigt einen Bodenmacherzylinder einer solchen Papierbeutelmaschine. Auf einem Bodenmacherzylinder werden die Einschläge eines zuvor aufgezogenen Endes eines Papierschlauches eingeschlagen und miteinander verleimt, so dass sie den Boden eines Papierbeutels bilden. Zum Zulegen des Bodens dienen Greiferfinger, die sowohl in axialer als auch in tangentialer Richtung des Bodenmacherzylinders relativ zu diesem bewegt werden. Um die Greiferfinger in Bewegung zu versetzen, werden diese teilweise mit Kräften beaufschlagt, die von Steuerkurven bereitgestellt werden.The invention relates to a bottom opening station of a paper bag machine according to the preamble of claim 1.
Paper bag machines have long been known. For example, the shows DE 197 02 144 A1 Elements of such devices. The Patent DE 1 080 846 shows a bottoming cylinder of such a paper bag machine. On a bottom maker cylinder, the impacts of a previously drawn-up end of a paper tube are wrapped and glued together to form the bottom of a paper bag. To put the soil serve gripper fingers, which are moved in both the axial and in the tangential direction of the Bodenmacherzylinders relative to this. In order to move the gripper fingers in motion, they are partially acted upon by forces that are provided by control cams.

Ein weiteres Element einer solchen Papierbeutelmaschine wird in der Patentschrift DE 17 61 992 C3 gezeigt. Das dort vorgestellte so genannte Henkelaggregat dient zum Anbringen von Traggriffen an einen bereits fertiggestellten Papierbeutel. Dazu wird ein Papierstreifen von einem Greifer auf einem Zylinder festgelegt, vorgebrochen, gefalzt, mit Leim versehen und letztendlich auf den Beutel aufgeklebt. Auf den Greifer wirkt eine von einer Feder bereitgestellte Kraft in der Art, dass der Papierstreifen ständig von dem Greifer auf der Zylinderoberfläche gehalten wird. Nach dem Verkleben des Traggriffes mit dem Papierbeutel wird der Greifer mittels einer Steuerkurve angehoben und zwecks Ergreifens eines neuen Papierstreifens wieder abgesenkt.Another element of such a paper bag machine is in the Patent DE 17 61 992 C3 shown. The so-called handle unit presented there serves to attach carrying handles to an already finished paper bag. For this purpose, a paper strip is fixed by a gripper on a cylinder, pre-broken, folded, provided with glue and finally glued to the bag. The gripper is acted upon by a spring provided by a spring in such a way that the paper strip is constantly held by the gripper on the cylinder surface. After bonding the carrying handle with the paper bag, the gripper is raised by means of a control cam and lowered again for the purpose of gripping a new paper strip.

Die Druckschrift DE 41 15 161 A1 zeigt einen Ausschnitt eines Bodenmacherzylinders einer solchen Maschine. Dieser Bodenmacherzylinder ist das zentrale Bauteil einer jeden Beutelmaschine. In der Regel wird auf diesem Zylinder die Bodenbildung durchgeführt. Zur Öffnung dieses Bodens ist es jedoch zunächst notwendig, dass die Schlauchstücke, welche zuvor vereinzelt worden sind, zunächst an die Bodenöffnungsstation beziehungsweise den Bodenöffnungszylinder übergeben werden. Dort werden sie durch verschiedene Maßnahmen arretiert. Zu diesen Maßnahmen gehört oft die Beaufschlagung der Schlauchstücke mit Vakuum auf diesen Zylinder. In der Regel spielen jedoch Greifer eine Rolle. Die Schlauchstücke werden in diesen Beutelmaschinen bekanntlich in der Richtung der Schlauchsymmetrieachse gefördert. An den Seiten dieser Schlauchstücke oder in den Seitenfalten derselben werden neben den vorgenannten Vakuumbefestigungsmitteln daher auch Greifer zum Einsatz kommen. Naturgemäß werden in der Regel zwei Greifer eingesetzt, wobei auch die Verwendung eines oder gar mehrerer Greifer möglich erscheint. Beide Greifmechanismen, Vakuum und Greifer, werden oft zueinander ergänzend eingesetzt. Der Greifer wird hierbei mit einer Kraft beaufschlagt, welche ihn zum Zugreifen bringt, das heißt, dass der Greifer während der ganzen Zeit des Zugreifens aktiv mit einer Kraft beaufschlagt werden muss. Diese Kraft wird in der Regel von einem Kurvenpaket bereit gestellt. Die Zeit, während der der Beutel beziehungsweise das Schlauchstück, aus dem der Beutel gebildet werden wird, von dem Greifer oder den beiden Greifern gehalten werden muss, ist von der gewünschten Größe des zu bildenden Bodens abhängig. Daher werden bei der Änderung des Schlauchformates beziehungsweise der gewünschten Sacklänge Einstellungen zur formatgerechten Steuerung des Greifers notwendig. Die Kraft, die auf den Greifer ausgeübt wird, kommt in der Regel dadurch zustande, dass ein Stößel bei der Umdrehung des Bodenöffnungszylinders an einem Kurvenpaket entlang fährt, welches den Stößel so lange mit einer Kraft beaufschlagt, wie die Sackbestandteile beziehungsweise das Schlauchstück gehalten werden muss. Wird die gewünschte Bodengröße verändert, muss dieses Kurvenpaket daher völlig ausgetauscht werden. Diese Austauscharbeiten und die Bevorratung zahlreicher geeigneter Kurvenpakete für verschiedene Bodengrößen sind aufwändig.The publication DE 41 15 161 A1 shows a section of a Bodenmacherzylinders such machine. This floor cylinder is the central component of every bag machine. As a rule, soil formation is carried out on this cylinder. For the opening of this bottom, however, it is first necessary that the pieces of tubing, which have been previously isolated, are first passed to the bottom opening station or the bottom opening cylinder. There they are arrested by various measures. These measures often include applying the hose pieces with vacuum to this cylinder. As a rule, grabbers play a role. The pieces of hose are known to be conveyed in these bag machines in the direction of the tube axis of symmetry. On the sides of these pieces of tubing or in the side folds of the same, therefore, grippers are used in addition to the aforementioned vacuum fastening means. Naturally, two grippers are usually used, whereby the use of one or even more grippers seems possible. Both gripping mechanisms, vacuum and gripper, are often used in addition to each other. In this case, the gripper is subjected to a force which makes it accessible, that is to say that the gripper must be actively acted on during the entire time of the access. This power is usually provided by a curve package. The time during which the bag or piece of tubing from which the bag will be formed must be held by the gripper or the two grippers depends on the desired size of the floor to be formed. Therefore, when changing the tube format or the desired bag length settings for format-appropriate control of the gripper necessary. The force exerted on the gripper is usually due to the fact that a plunger moves during the rotation of the bottom opening cylinder along a set of curves, which acts on the plunger as long as a force as the bag components or the hose piece must be kept , If the desired floor size is changed, this curve package must therefore be completely replaced. These replacement work and the storage of numerous suitable cam packages for different floor sizes are complex.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine Bodenöffnungsstation für Beutelmaschinen zu schaffen, welche bei einer Änderung der gewünschten Beutellänge ohne langwierige Einstellarbeiten und ohne die Bevorratung von Kurvenpaketen auskommt.The object of the present invention is therefore to provide a bottom opening station for bag machines, which manages with a change in the desired bag length without tedious adjustments and without the storage of cam packages.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Zum Verständnis des Anspruchs 1 ist es wichtig zu verstehen, dass nach dem Stand der Technik die zur Arretierung eines Beutelabschnitts notwendige Kraft vor allem in Richtung auf die Drehachse des Bodenöffnungszylinders wirkt. Der Beutelabschnitt wird also gegen den Zylinder gedrückt. Die Länge dieser Kraftbereitstellung ist bei dem Stand der Technik, wie erwähnt, von der Länge des Kurvenpaketes abhängig. Ist das Kurvenpaket passiert, verebbt die arretierende Kraft und der Greifer öffnet sich.This object is solved by the characterizing features of claim 1. To understand the claim 1, it is important to understand that according to the prior art, the necessary force for locking a bag portion force acts mainly in the direction of the axis of rotation of the bottom opening cylinder. The bag section is thus pressed against the cylinder. The length of this power supply is in the prior art, as mentioned, depending on the length of the curve package. Once the curve package has passed, the arresting force stops and the gripper opens.

Bei der vorliegenden Erfindung wird der Greifer während seiner ganzen Umdrehung zunächst von einer in Richtung auf die Achse des Greiferzylinders wirkenden Kraft beeinflusst. Lediglich wenn der Greifer geöffnet wird, wirkt dieser ersten Kraft eine zweite Kraft entgegen, die den Greifer öffnet. Vorteilhafterweise wird die erste Kraft von einem Federelement, einer magnetischen Kraft oder einer anderen Kraft aufbringenden Vorrichtung bereit gestellt.In the present invention, the gripper is initially influenced during its entire revolution by a force acting in the direction of the axis of the gripper cylinder. Only when the gripper is opened, this first force counteracts a second force that opens the gripper. Advantageously, the first force is provided by a spring element, a magnetic force or another force applying device.

Die zweite Kraft wird in der Regel von zwei Kurvenpaketen bereitgestellt werden, wobei die Lage dieser beiden Kurvenpakete in Umfangsrichtung veränderlich ist. Durch diese Veränderbarkeit der Relativposition der beiden Kurvenpakete kann vorteilhafterweise eine Anpassung der Öffnungszeitpunkte des Greifers an die gewünschte Beutellänge vorgenommen werden.The second force will usually be provided by two cam packages, the position of these two cam packages is variable in the circumferential direction. Due to this variability of the relative position of the two cam packages, it is advantageously possible to adapt the opening times of the gripper to the desired bag length.

Die Figur 1 zeigt eine Ansicht in radialer Richtung auf einen Ausschnitt einer erfindungsgemäßen Bodenöffnungsstation. Dieser Ausschnitt zeigt den Bodenöffnungszylinder 1, welcher eine Welle 2 umfasst. Diese Welle 2 ist im nicht dargestellten Maschinengestell gelagert und ist antreibbar. Auf diese Welle 2 ist ein Auflagezylinder 3 aufgebracht, auf welchem das Schlauchstück 4 geführt und durch den Greiferfinger 5 gehalten wird. Der Greiferfinger 5 ist mit einem Stößel 6 verbunden. Dieser Stößel 6 ist in Bohrungen im Auflagezylinder 3 derart gelagert, dass er drehbar und axial verschiebbar ist. Die Druckfeder 7 beaufschlagt den Stößel 6 derart mit einer Kraft, dass der Greiferfinger 5 immer in axialer Richtung gegen den das Schlauchstück 4 führenden Teil des Auflagezylinders 3 drückt. Aus der Fig. 2 ist zu erkennen, dass eine Zugfeder 8 auf den Hebel 9 in Richtung auf die Welle 2 eine im wesentlichen radial wirkende Kraft ausübt. Der Greiferfinger 5, der an dem Hebel 9 befestigt ist, drückt somit das Schlauchstück 4 in radialer Richtung auf den das Schlauchstück 4 führenden Teil des Auflagezylinders 3. Während des Betriebes der Bodenöffnungsstation rotiert der Bodenöffnungszylinder 1 in Richtung des Pfeiles A.The FIG. 1 shows a view in the radial direction on a section of a floor opening station according to the invention. This section shows the bottom opening cylinder 1, which comprises a shaft 2. This shaft 2 is mounted in the machine frame, not shown, and is driven. On this shaft 2, a support cylinder 3 is applied, on which the hose piece 4 is guided and held by the gripper finger 5. The gripper finger 5 is connected to a plunger 6. This plunger 6 is mounted in holes in the support cylinder 3 such that it is rotatable and axially displaceable. The compression spring 7 acts on the plunger 6 with a force such that the gripper finger 5 always presses in the axial direction against the part of the support cylinder 3 leading the hose piece 4. From the Fig. 2 It can be seen that a tension spring 8 exerts on the lever 9 in the direction of the shaft 2 a substantially radially acting force. The gripper finger 5, which is fastened to the lever 9, thus presses the hose piece 4 in the radial direction on the part of the support cylinder 3 leading the hose piece 4. During operation of the floor opening station, the floor opening cylinder 1 rotates in the direction of the arrow A.

Zum Erfassen und zum Freigeben des zu formenden Bodens eines Schlauchstücks 4 muss der Greiferfinger 5 zwei Mal von dem das Schlauchstück 4 führende Teil des Auflagezylinders 3 entfernt werden. Zu diesem Zweck sind Steuerkurven vorgesehen, die auf den Stößel 6 beziehungsweise auf den Hebel 9 in der im Folgenden beschriebenen Weise wirken: Eine der axialen Steuerkurven 10, 12 wirkt auf das Schleifstück 14 und vermittelt so dem Stößel 6 ein Kraft. Diese Kraft ist derjenigen der Druckfeder 7 entgegen gerichtet und größer als diese, so dass letztendlich der Greiferfinger 5 in axialer Richtung von dem Schlauchstück 4 entfernt wird. In etwa gleichzeitig wirkt einer der beiden radiale Steuerkurven 11, 13 auf ein nicht sichtbares Schleifstück, welches an dem Hebel 9 angebracht ist. Die durch die radiale Steuerkurve 11 aufgebrachte Kraft wirkt der Zugfeder 8 entgegen und bewirkt ein zusätzliches Anheben des Greiferfingers 5 in radialer Richtung. Der Greiferfinger 5 befindet sich nun in einer so genannten geöffneten Position. Die Steuerkurven 10, 11, 12, 13 sind an einer Trägereinheit 15 befestigt, welcher wiederum mit dem Maschinengestell verbunden ist. Um einen konstanten Abstand zwischen der Trägereinheit 15 und der Welle 2 zu gewährleisten, ist zwischen diesen beiden Elementen ein Stützlager 16 vorgesehen.For detecting and releasing the bottom of a hose piece 4 to be formed, the gripper finger 5 has to be removed twice from the part of the support cylinder 3 which guides the hose piece 4. For this purpose, control cams are provided which act on the plunger 6 and on the lever 9 in the manner described below: One of the axial control cams 10, 12 acts on the contact strip 14 and thus gives the plunger 6 a force. This force is directed and greater than that of the compression spring 7, so that ultimately the gripper finger 5 is removed in the axial direction of the hose piece 4. At about the same time, one of the two radial control cams 11, 13 acts on a non-visible contact piece, which is attached to the lever 9. The applied by the radial cam 11 force counteracts the tension spring 8 and causes an additional lifting of the gripper finger 5 in the radial direction. The gripper finger 5 is now in a so-called open position. The cams 10, 11, 12, 13 are fixed to a support unit 15, which in turn is connected to the machine frame. In order to ensure a constant distance between the carrier unit 15 and the shaft 2, a support bearing 16 is provided between these two elements.

Die eigentliche Bodenöffnung erfolgt nun dadurch, dass der Greiferfinger 5 das erste Kurvenpaket, bestehend aus den Steuerkurven 12 und 13, erreicht. In diesem Moment wird das vorrauslaufende Ende des Schlauchstückes 4 mit Hilfe eines nicht dargestellten Vakuumsaugers angehoben. Während dieser Anhebebewegung laufen die Schleifstücke auf die Steuerkurven 12, 13, so dass der Greiferfinger 5 geöffnet wird. Nach dem Passieren dieser Steuerkurven schließt sich der Greiferfinger 5 wieder, wodurch das Schlauchstück 4 mit seiner oberen Seite auf dem Auflagezylinder 3 arretiert wird. Durch die Rotationsbewegung des Bodenöffnungszylinders 1 wird das Schlauchstück 4 aufgezogen. Erreicht der Greiferfinger 5 die Steuerkurven 10, 11, wird der Greiferfinger 5 wieder geöffnet, so dass das Schlauchstück 4 mit dem nun geöffneten Boden aus der Bodenöffnungsstation entfernt und einer weiteren Verarbeitungsstation der Papierbeutelmaschine zugeführt werden kann.The actual bottom opening now takes place in that the gripper finger 5 reaches the first set of curves, consisting of the control cams 12 and 13. At this moment, the vorrauslaufende end of the tube piece 4 is raised by means of a vacuum suction, not shown. During this lifting movement, the sliding pieces run on the control cams 12, 13, so that the gripper finger 5 is opened. After passing these cams, the gripper finger 5 closes again, whereby the tube piece 4 is locked with its upper side on the support cylinder 3. By the rotational movement of the bottom opening cylinder 1, the hose piece 4 is raised. When the gripper finger 5 reaches the control cams 10, 11, the gripper finger 5 is opened again, so that the hose piece 4 can be removed from the bottom opening station with the now open bottom and fed to a further processing station of the paper bag machine.

Um den Zeitpunkt, zu dem der Greiferfinger 5 das Schlauchstück 4 nach erfolgter Bodenöffnung wieder frei gibt, der gewünschten Größe des Bodens anpassen zu können, sind die Steuerkurven 10, 11 in Richtung des Doppelpfeiles B verschiebbar. Zu diesem Zweck sind die Steuerkurven 10, 11 auf nicht gezeigte Weise schnell lösbar mit der Trägereinheit 15 verbunden.In order to adjust the time at which the gripper fingers 5 the tube piece 4 again after the bottom opening, the desired size of the soil to adjust, the cams 10, 11 in the direction of the double arrow B are displaced. For this purpose, the cams 10, 11 in a manner not shown connected to the carrier unit 15 quickly releasably.

Die Fig. 3 zeigt eine bereits bekannte Bodenöffnungsstation 1. Diese Bodenöffnungsstation 1 umfasst einen Greiferfinger 1. Dieser Greiferfinger 1 ist an einem Stößel 6 montiert, welcher wiederum über Druckfeder 7 von dem das Schlauchstück 4 führende Teil des Auflagezylinders 3 mit einer solchen Kraft beaufschlagt, dass der Greiferfinger 5 sich in einer vom Schlauchstück 4 entfernten Position befindet. Die Festlegung des Schlauchstückes 4 erfolgt mithilfe der axialen Steuerkurve 10 und der radialen Steuerkurve 11. Zur Arretierung des Schlauchstücks 4 vermittelt zunächst die Steuerkurve 11 eine Kraft in radialer Richtung, so dass der Stößel 6 verdreht und der Greiferfinger 5 dadurch angehoben wird. Anschließend vermittelt die Steuerkurve 10 dem Greiferfinger 5 eine Kraft, so dass dieser gegen die Kraft der Druckfeder 7 in Richtung auf den das Schlauchstück 4 führende Teil des Auflagezylinders 3. Diese Kraft muss so lange aufrecht erhalten werden, wie das Schlauchstück 4 arretiert werden soll. Diese Dauer und damit die Abschnittslänge der Steuerkurve 10 und 11 ist abhängig von der vorgesehenen Bodengröße des Schlauchstückes 4. Bei Veränderung der Bodengröße ist die Abschnittslänge der Steuerkurve 10 und 11 anzupassen. Dies geschieht bei der einen bekannten Bodenöffnungsstation durch Auswechseln der Steuerkurve 10 und Verschieben von Steuerkurve 11.

The fixing of the hose piece 4 takes place with the aid of the axial control cam 10 and the radial control cam 11. To lock the hose piece 4, first the control cam 11 imparts a force in the radial direction, so that the plunger 6 is rotated and the gripper finger 5 is thereby lifted. Subsequently, the control cam 10 gives the gripper finger 5 a force so that it against the force of the compression spring 7 in the direction of the hose piece 4 leading part of the support cylinder 3. This force must be maintained as long as the piece of hose 4 is to be locked. This duration and thus the section length of the control cam 10 and 11 is dependent on the intended floor size of the hose piece 4. When changing the floor size, the section length of the control cam 10 and 11 must be adjusted. This is done in a known floor opening station by replacing the control cam 10 and moving cam 11.
