Vorrichtung zur Stapelung von SäckenDevice for stacking sacks
Die Erfindung bezieht sich auf eine Vorrichtung zur Stapelung von Säcken. Es sind Haschinen zur Herstellung von Säcken bekannt, bei denen eine in geradliniger Bewegung befindliche Kunststoffhülle in vorgegebenen Intervallen zerschnitten und verschweißt wird. Am Ausgang dieser Maschine werden die Säcke flach und im wesentlichen horizontal gestapelt.The invention relates to a device for stacking sacks. They are machines for making of sacks known in which a straight-line movement of plastic casing at predetermined intervals is cut and welded. At the exit of this machine the bags become flat and essentially horizontal stacked.
Bei einem bekannten Verfahren werden die Säcke mit Hilfe von Riemen vorwärts bewegt bzw. vorwärts geschleudert und fallen unter der Wirkung der Schwerkraft auf die bereits aufgestapelten Säcke. Bei einem anderen bekannten Verfahren finden Greifer Verwendung, die die Säcke bis zum Sackstapel bewegen, auf den sie dann abgelegt werden. Diese bekannten Einrichtungen und Verfahren arbeiten jedoch nur dann befriedigend, wenn die Säcke eine verhältnismässig große Stärke und bestimmte Formen aufweisen. Werden die Säcke dagegen aus sehr dünnem Material und mit großer Länge hergestellt, so ergeben sich durch die Geschmeidigkeit des Materiales und die große Sacklänge Palten, die eine unregelmäßige Stapelung zur Folge haben.In a known method, the sacks are moved forward or thrown forward with the aid of belts and fall under the action of gravity on the bags that have already been piled up. With another well-known Processes are used with grippers that move the sacks to the stack of sacks on which they are then placed. These known devices and methods work, however only satisfactory if the sacks are relatively thick and have certain shapes. Will The sacks, on the other hand, are made of very thin material and are of great length, which is the result of their flexibility of the material and the great length of the bag, which results in irregular stacking.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Stapelung von Säcken zu entwickeln, die die Nachteile der bekannten Ausführungen vermeidet.The invention is therefore based on the object of a To develop a device for stacking sacks, which avoids the disadvantages of the known designs.
Die Erfindung geht aus von einer Vorrichtung zur Stapelung von Säcken, insbesondere aus Kunststoff, am Ausgang einer Maschine zur Herstellung von Säcken aus einer Hülle, mit zwei Schweißbacken, von denen wenigstens einer beweglich ist und ein Schneidorgan zum Abschneiden der Hülle trägt.The invention is based on a device for Stacking of sacks, in particular made of plastic, at the exit of a machine for the production of sacks a shell, with two welding jaws, of which at least one is movable and a cutting element for cutting off the shell wears.
Bei einer solchen Vorrichtung besteht die Erfindung im wesentlichen darin, daß der untere Schweißbacken einen sich in Bewegungsrichtung der Hülle erstreckenden Rand aufweist, an dem ein Träger derart zur Anlage kommt, daß hierdurch das eine Ende der Säcke nach dem Schneidvorgang kXeiaartig erfaßt wird, und daS ferner der Träger eine Stützfläche für die aufgestapelten Säcke aufweist, über die er mit einem Halter zusammenwirkt, der hinter dem oberen Schweiß— backen angeordnet ist und sich parallel zu diesem Schweiß— backen bewegt.It is with such a device that the invention exists essentially in the fact that the lower welding jaw one has in the direction of movement of the envelope extending edge on which a carrier comes to rest in such a way that thereby one end of the sack after the cutting process kXeia-like is detected, and that the carrier also has a support surface for the stacked sacks, over which it is a holder cooperates, which is arranged behind the upper welding jaw and is parallel to this welding jaw baking moves.
Die sehr einfach ausgebildete erfindungsgemäße Vorrichtung ermöglicht ein flaches Aufstapeln von Säcken, wobei der Sackstapel an einem Ende zwischen dem in Bewegungsrichtung des Kunststoffmateriales weisenden Rand des unteren Schweißbackens und dem Träger eingeklemmt ist. Der er— findungsgemäß vorgesehene Halter wirkt mit dem Träger so zusammen, daß die Säcke hierdurch zusammengedrückt werden, während sich der Träger von dem erwähnten Rand des unteren Schweißbackens entfernt, w& einen neuen Sack in die Stapel— lage zu bringen.The very simply designed device according to the invention enables sacks to be stacked flat, the sack stack being clamped at one end between the edge of the lower welding jaw pointing in the direction of movement of the plastic material and the carrier. The inven- tion provided according holder cooperates with the carrier together so that the bags are compressed thereby, whilst the carrier from said edge of the lower welding jaw away to bring a new location w & bag in the stack.
Die erfindungsgemäße Torrichtung ermöglicht eine, aus-909881/1342 The gate direction according to the invention enables one, from 909881/1342
gezeichnete gegenseitige Ausrichtung der aufzustapelnden Säcke und vermeidet alle Nachteile der bekannten Ausführungen. Die Säcke werden insbesondere auch während ihrer Bewegung durch den Halter festgehalten, der sich bereits vor dem Abschneiden des Sackes auf die Kunststoffhülle aufsetzt. drawn mutual alignment of the bags to be stacked and avoids all the disadvantages of the known designs. The bags are held in particular during their movement by the holder, which is already before cutting the sack on the plastic sleeve.
Alle mit statischer Aufladung verbundenen Erscheinungen, insbesondere ein gegenseitiges Abheben von flach übereinander gestapelten Säcken, werden bei der erfindungsgemäßen Vorrichtung vermieden. Durch die flache Stapelung ist es andererseits möglich, sowohl kurze als auch lange säcke gleich gut auszurichten, was bei einer rittlings hängenden Stapelung nicht der Fall ist. Man kann ferner bei Verwendung einer seitlichen Schweißnaht auch kleine Säckchen ausrichten. All phenomena associated with static electricity, in particular a mutual lifting off from flat on top of each other stacked sacks are avoided in the device according to the invention. Because of the flat stacking it is On the other hand, it is possible to have both short and long bags equally well aligned, which is not the case with a straddling stacking. One can also use align small bags with a lateral weld seam.
Die erfindungsgemäße Vorrichtung zeichnet sich ferner durch einen sehr geringen Raumbedarf aus; sie kann ohne weiteres am Ausgang jeder Maschine zur Sackherstellung vorgesehen werden. The device according to the invention is also characterized by a very small space requirement; she can without more can be provided at the exit of each machine for making sacks.

In den Figuren 1,2 und 3 ist der Ausgang einer Maschine zur Sacklierstellung veranschaulicht. Er enthält einen Tisch 1, auf dem sich die Kunststoffhülle 2 in Richtung des Pfeiles F bewegt. Weiterhin sind zwei obere und untere Schweißbackeri 3,4 auf unterschiedlichen Seiten der Hülle 2 angeordnet. Sie enthalten jeweils einen eleketrischen Widerstand 5 bzw. 6, der das thermische Verschweißen der einen Seite der Hülle 2 zur Bildung eines Sackbodens bewirkt.In FIGS. 1, 2 and 3, the output of a machine for positioning bags is illustrated. He contains a table 1 on which the plastic sleeve 2 is in the direction of arrow F moves. Furthermore, there are two upper and lower welding jaws 3, 4 on different sides of the Sheath 2 arranged. They each contain an electrical resistor 5 or 6, which the thermal welding causes one side of the shell 2 to form a sack bottom.
Der untere Schweißbacken 4 ist feststehend angeordnet, während der obere Schweißbacken 3 in Richtung des Pfeiles F1 beweglich ist, so daß er während des Verschweißens der von den beiden Backen erfaßten Kunststoffhülle in Berührung mit dem unteren Schweißbacken 4 kommt.The lower welding jaw 4 is arranged in a stationary manner, while the upper welding jaw 3 is movable in the direction of the arrow F 1 , so that it comes into contact with the lower welding jaw 4 during the welding of the plastic casing grasped by the two jaws.
Der obere Schweißbacken ist in bekannter Weise fest mit einem Schneidorgan 7 verbunden, das sich in Bewegungsrichtung der Kunststoffhülle hinter dem Schweißwiderstand 5 befindet.The upper welding jaw is fixed in a known manner connected to a cutting member 7, which extends in the direction of movement the plastic cover behind the welding resistor 5 is located.
Der untere Backen 4 besitzt einen Rand 8, der sich von dem Backen aus in Bewegungsrichtung der Hülle erstreckt und an dem der Träger 9 eines Sackstapels zur Anlage kommen kann. Dieser Träger 9 ist in Richtung des Doppelpfeiles F2 relativ zu dem unterem Backen 4 gleitbeweglich und steht unter der Wirkung von Federn 10, die sich am Gehäuse 11 der Maschine abstützen.The lower jaw 4 has an edge 8 which extends from the jaw in the direction of movement of the casing and on which the carrier 9 of a stack of sacks can come to rest. This carrier 9 is slidable in the direction of the double arrow F 2 relative to the lower jaw 4 and is under the action of springs 10 which are supported on the housing 11 of the machine.
Zwischen der Oberseite 9a des Trägers 9 und der Unterseite 8a des Randes 8 des unteren Schweißbackens 4 werdenBetween the top 9a of the carrier 9 and the bottom 8a of the edge 8 of the lower welding jaw 4 are
909881/1342909881/1342
die bereits aufgestapelten Säcke 12, die sich auf der Oberseite des Trägers 9a abstützen, mit ihrem einen Ende festgehalten.the already stacked bags 12 that are on the Support the top of the carrier 9a, held at one end.
Hinter dem Schneidorgan 7 und oberhalb des Trägers 9 ist ein Halter 13 gleitbeweglich angeordnets der an einer seiner unteren Kanten eine Druckluftleitung 14 aufweist^ die mit Öffnungen 15 versehen ist, durch die Druckluft auf das abgeschnittene Ende eines Sackes bei der Stapelbewegung geblasen wird.Behind the cutting organ 7, and above the support 9 is a holder 13 slidably s disposed on one of its lower edges, a pressurized air line 14 which is provided with openings 15 ^, is blown through the compressed air to the cut end of a bag in the stack movement.
Wie der obere Schweißbacken 3, so wird auch der Halter 13, der die Form einer stange aufweist, durch bekannte, in der Zeichnung nicht veranschaulichte mechanische Einrichtungen in Richtung des Pfeiles F, angetrieben«, wobei er mit den auf der Oberseite 9a des Trägers 9 aufliegenden Säkken 12 in Berührung kommt.Like the upper welding jaw 3, so is the holder 13, which has the shape of a rod, by known mechanical means not illustrated in the drawing in the direction of arrow F, driven «, where he comes into contact with the sacks 12 resting on the upper side 9a of the carrier 9.
Auf den Träger 9 folgend kann ein feststehender Tisch 16 angeordnet werden, der eine geneigte Fläche aufweist und zur Aufnahme des freien Endes 12a der Säcke dient a Following the carrier 9 can be arranged a fixed table 16 having an inclined surface and serves for receiving the free end 12a of the bags a
Die Wirkungsweise der erfindungsgemäßen Stapelvorrichtung ist folgendermaßenϊThe mode of operation of the stacking device according to the invention is as followsϊ
In Figur 1 ist die Torrichtung in der Lage veranschaulicht, die sie während der Bewegung einer vorgegebenen, für die Bildung eines Sackes benötigten Länge der Kunststoffhülle 2 einnimmt. In dieser Phase befinden sich der obere Schweißbacken 3, das Schneidorgan 7 und der Halter 13 in der oberen Lage.In Figure 1, the gate direction is illustrated in the position that it during the movement of a predetermined, for the formation of a sack required length of the plastic sleeve 2 occupies. In this phase are the upper ones Welding jaws 3, the cutting element 7 and the holder 13 in the upper layer.
Sobald die Kunststoffhülle 2 zum Stillstand gekommen ist, wird der Halter 13 in Richtung des Pfeiles F, bewegt.As soon as the plastic sleeve 2 has come to a standstill is, the holder 13 is moved in the direction of arrow F.
909881/1342909881/1342
Er drückt die Hülle 2 auf den Stapel der auf dem träger 9 ruhenden Säcke 12 (vgl. Figur 2). Anschließend wird der obere Schweißbacken 3 in Richtung des Pfeiles F1 abgesenkt, so daß nacheinander das Abtrennen und Terschweißen der Kunststoffhülle erfolgen.He presses the casing 2 onto the stack of sacks 12 resting on the carrier 9 (see FIG. 2). The upper welding jaw 3 is then lowered in the direction of arrow F 1 , so that the plastic casing is separated and welded one after the other.
Sobald die Hülle geschnitten ist* setzt der Halter 13» der momentan in der Lage gemäß Figur 2 stehen geblieben ist, seine Abwärtsbewegung in Richtung des Pfeiles P, fort und drückt hierdurch den Träger 9 gegen, die Wirkung der Federn 10 nach unten ι dadurch wird der Träger 9 vom Rand 8 des unteren Schweißbaekens 4 abgehoben. Wie aus Figur 3 ersichtlich ist, kann dann das abgeschnittene Ende 1?a des soeben hergestellten Sackes 17 unter der Wirkung seines Eigengewichtes auf den bereits vorhandenen stapel von Säcken 12 herunterfallen. TJm diese Bewegung zu erleichtern, kann man durch die Öffnungen 15 der Leitung 14 einen Druckluftstrahl auf das Ende 1?a des Sackes 17 richten.As soon as the cover is cut * the holder 13 » which momentarily stopped in the position according to FIG is, its downward movement in the direction of arrow P, continues and thereby presses the carrier 9 against, the effect of Springs 10 downward as a result of which the carrier 9 is removed from the edge 8 of the lower welding jaw 4 lifted off.

In this last-mentioned embodiment there is an additional mechanical device for movement of the lower welding jaw 4 required.
In Figur 4 ist eine Sackstapelvorrichtung veranschaulicht, die ebenso wie die erläuterten Ausführungsbeispiele einen oberen und einen unteren Schweißbaeken 3 bzw. 4 aufweist, die oberhalb bzw. unterhalb der Kunststoffhülle 2 angeordnet sind und ;}e einen elektrischen Widerstand 5 bzw. enthalten* der das thermische Verschweißen der einen Seite der Hülle 2 zur Bildung des Sackbodens bewirkt.FIG. 4 shows a sack stacking device which, like the exemplary embodiments explained has an upper and a lower welding beam 3 and 4, respectively, which are arranged above or below the plastic casing 2 are and;} e an electrical resistor 5 or contain * the thermal welding of one side causes the shell 2 to form the bottom of the bag.
Gegen die Seite 8a des Randes 8 des unteren Backens 4 stützt sich das eine Ende eines Tisches 18, auf dem die Säcke aufgestapelt sind. Diese säcke sind zwischen dem Rand 8 und dem Tisch 18 eingeklemmt. Der Tisch ist im Bereich seines anderen Endes um eine fest mit dem Maschinengehäuse verbundene Achse 19 schwenkbeweglich gelagert. Der Tisch wird durch eine Feder 20 in Berührung mit dem Rand 8 gehalten. Die Feder 20 ist bei 21 am Gehäuse befestigt und drückt mit ihrem Ende 22 den Tisch 18 nach oben.Against the side 8a of the edge 8 of the lower jaw 4 is supported by one end of a table 18 on which the Bags are piled up. These sacks are between the edge 8 and the table 18 clamped. The table is fixed to the machine housing in the area of its other end connected axis 19 pivotally mounted. The table is held in contact with the rim 8 by a spring 20. The spring 20 is attached to the housing at 21 and pushes the table 18 with its end 22 upwards.
Wie bei den bereits erläuterten Ausführungsbeispielen wirkt ein in Bewegungsrichtung hinter dem Schneidorgan 7 angeordneter Halter 13 gegen die Kraft der Feder 20 auf den Tisch 18 und drückt den Tisch 18 soweit nach unten, daß ein neuer Sack 12 in den Spalt zwischen dem Rand 8 und dem Tisch 18 eintreten kann«As in the exemplary embodiments already explained, an acts behind the cutting element 7 in the direction of movement arranged holder 13 against the force of the spring 20 on the table 18 and presses the table 18 downwards so far, that a new sack 12 can enter the gap between the edge 8 and the table 18 "
Der Tisch 18 kann aus zwei Teilen 18a,18b (vgl. Figur 5) bestehen, die um die Achse 19 schwenkbeweglich gelagert sind und unter der Wirkung von Federn 20a bzw. 20b stehen. Eine derartige Anordnung ermöglicht es, mit derThe table 18 can consist of two parts 18a, 18b (see FIG 5) exist, which are mounted pivotably about the axis 19 and under the action of springs 20a and 20b stand.
