Abstract

Durch Falten des flachgezogenen oberen und durch eine Schweißnaht geschlossenen Sackendes auf eine Hälfte der flachgedrückten Oberseite eines gefüllten Sackes entstehen diesen seitlich überragende Fahnen, die beseitigt werden müssen, um ansehnliche und gut transport- und lagerfähige Säcke zu erhalten. Eine Vorrichtung zum Umlegen dieser einen gefüllten Sack seitlich überragenden Fahnen besteht aus zwei in einem Maschinengestell geführten, auf die Sackoberseite absenkbaren und hebbaren, in Abförderrichtung der Säcke (31) frei auskragenden Faltleisten oder -stangen, deren äußeren Kanten die Faltkanten der umzulegenden Fahnen (33) bestimmen. In dem Maschinengestell (1) sind beidseits des auf einer Unterlage (30) stehenden Sackes Halter gelagert, die jeweils einen Rahmen (23) mit einem unter jeden der Fahnen (33) greifenden Zangenschenkel (24) tragen. In jedem Rahmen (23) ist ein mit einem Zangenschenkel (24) zangenartig zusammenwirkender oberer Zangenschenkel (25) gelagert. Die Halter sind zwischen einer äußeren Stellung, in der sich die Zangenenden seitlich oberhalb des Sackes befinden, und einer inneren Stellung, in der die unteren Zangenschenkel (24) die umgelegten Fahnen (33) auf Klebstoffstreifen (34) drücken, verlagerbar.By folding the flat top and closed by a weld seam on one half of the flattened upper side of a filled sack, this results in laterally protruding flags that have to be removed in order to obtain attractive and easily transportable and storable sacks. A device for folding over these one side of a filled sack consists of two folding strips or bars, which are guided in a machine frame and can be lowered and lifted on the top of the sack and project freely in the direction of removal of the sacks (31), the outer edges of which fold the edges of the flags (33 ) determine. Holders are mounted in the machine frame (1) on both sides of the sack standing on a base (30), each of which carries a frame (23) with pliers legs (24) that grip under each of the flags (33). In each frame (23) an upper pliers leg (25), which interacts with a pair of pliers legs (24), is mounted. The holders can be displaced between an outer position in which the ends of the pliers are laterally above the sack and an inner position in which the lower legs of the pliers (24) press the folded tabs (33) onto adhesive strips (34).

Description

Die Erfindung betrifft eine Vorrichtung zum Umlegen der einen gefüllten Sack seitlich überragenden Fahnen auf die mit Klebstoffstreifen versehene Sacküberseite nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for folding the flags projecting laterally from a filled sack onto the top side of the sack provided with adhesive strips according to the preamble of patent claim 1.

In der am 26.4.1984 eingereichten Anmeldung der Anmelderin mit dem Titel "Vorrichtung zum Verschließen gefüllter Säcke" ist eine Vorrichtung beschrieben worden, die die Sackwandungen beidseits des straff gehaltenen oberen Sackendes zur Bildung einer im wesentlichen ebenen Sackoberseite gegen die Sackfüllung andrückt und anschliessend das mit einer Kopfschweißnaht versehene Sackende auf eine mit Klebstoffstreifen versehene Hälfte der Sackoberseite umlegt und andrückt. Durch diese Art des Umlegens und Verklebens des flachgezogenen oberen Sackendes mit der Sackoberseite werden den Sack seitlich überragende Fahnen gebildet, die aus seitlichen dreieckigen Zwickeln und dem mittig mit diesen verbundenen rechteckigen Streifen des flachgezogenen Teils des oberen Sackendes bestehen. Um ansehnliche und gut transport- und lagerfähige Säcke und insbesondere Großsäcke zu schaffen, ist es erforderlich, diese Fahnen zu beseitigen.In the application filed on April 26, 1984 by the applicant with the title "Device for Closing Filled Sacks", a device has been described which presses the bag walls on both sides of the taut upper bag end to form a substantially flat top of the bag against the bag filling and then with of a head weld seam end of the sack folded onto a half of the top of the sack provided with adhesive strips and pressed on. This type of folding and gluing the flat top of the sack to the top of the sack makes the sack project laterally Flags formed, which consist of triangular gussets on the side and the rectangular strip of the flat part of the upper end of the sack connected to the center of the gusset. In order to create attractive and easily transportable and storable sacks, especially large sacks, it is necessary to remove these flags.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, mit der sich die den gefüllten Sack seitlich überragenden Fahnen auf die mit Klebstoffstreifen versehene Sackoberseite umlegen und andrücken lassen.The object of the invention is therefore to provide a device of the type specified at the outset, with which the flags projecting laterally beyond the filled sack can be folded down and pressed onto the top of the sack provided with adhesive strips.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing features of patent claim 1.

Mit der erfindungsgemäßen Vorrichtung lassen sich die umzulegenden Fahnen sicher erfassen, umlegen und auf die Klebstoff streifen aufdrücken, die durch die am 26.4.1984 angemeldete Vorrichtung der Anmelderin aufgetragen worden ist.With the device according to the invention, the flags to be flipped can be securely grasped, flipped over and pressed onto the adhesive strips, which was applied by the device registered by the applicant on April 26, 1984.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung, in deren einziger Figur eine Vorderansicht der Vorrichtung zum Umlegen der einen gefüllten Sack seitlich überragenden Fahnen dargestellt ist, näher erläutert.An embodiment of the invention is explained in more detail below with reference to the drawing, in the single figure of which a front view of the device for folding down the flags projecting laterally from a filled sack is shown.

Die Vorrichtung weist ein Maschinengestell auf, das aus nicht dargestellten Seitenteilen besteht, die durch die Quertraverse 1 miteinander verbunden sind. An die Quertraverse 1 sind beidseits Konsolen 2 angeschweißt, mit denen Parallellenker 3 drehbar verbunden sind. Die den Konsolen 2 abgewandten Enden der Parallellenker 3 sind an einem Arm 4 angelenkt, dessen Höhenlage verändert werden kann. Zu diesem Zweck ist mit dem Arm 4 ein Seil 5 einendig verbunden, welches über eine Umlenkrolle 6 geführt auf eine von einem Motor 7 angetriebene Seiltrommel 8 aufgewickelt bzw. von dieser abgewickelt werden kann. Beidseits des Arms 4 sind Halter 9 mit dem Arm 4 verschweißt, die in entgegengesetzte Richtung nach außen weisen. Mit den äußeren Enden der Halter 9 sind senkrecht nach unten ragende Führungsrohre 10 verbunden, in denen jeweils ein teleskopartig verschiebbares Rohr 11 geführt ist. Mit den unteren freien Enden der Rohre 11 sind jeweils Anärückfinger 12 verbunden. Zwecks Verschiebung der Rohre 11 weist jedes Führungsrohr 10 ein Langloch 13 auf, durch das ein Zapfen 14 nach außen ragt, der in das verschiebbare Rohr 11 eingeschraubt worden ist. An den nach außen ragenden Teil eines jeden Zapfens 14 greift jeweils die Kolbenstange 15 einer Kolbenzylindereinheit 16 an, die von dem Halter 9 getragen wird.The device has a machine frame which consists of side parts, not shown, which are connected to one another by the crossbar 1. Consoles 2 are welded to the crossbar 1 on both sides, with which parallel links 3 are rotatably connected. The ends of the parallel links 3 facing away from the brackets 2 are articulated on an arm 4, the height of which can be changed. For this purpose, a cable 5 is connected at one end to the arm 4, which is connected via a deflection roller 6 performed on a cable drum 8 driven by a motor 7 or can be unwound from this. Holders 9 are welded to the arm 4 on both sides of the arm 4 and point outward in the opposite direction. With the outer ends of the holder 9 vertically downwardly projecting guide tubes 10 are connected, in each of which a telescopically displaceable tube 11 is guided. Anärückfinger 12 are connected to the lower free ends of the tubes 11, respectively. For the purpose of moving the tubes 11, each guide tube 10 has an elongated hole 13 through which a pin 14 protrudes outwards, which has been screwed into the displaceable tube 11. The piston rod 15 of a piston-cylinder unit 16, which is carried by the holder 9, engages on the outwardly projecting part of each pin 14.

An das untere Ende des Arms 4 ist ein querverlaufendes Tragjoch 17 angeschweißt, welches beidendig mit Lagerplatten 18-fest verbunden ist. Jeweils zwei Lagerplatten sind durch zwei Wellen 19 und 20 miteinander verbunden, wobei auf die Welle 20 der Lenker 21 und auf die Welle 19 der Lenker 22 aufgesetzt ist. Die den Wellen 19 und 20 abgewandten Enden der Lenker 21 und 22 tragen einen Zangenrahmen 23, der einen festen Zangenschenkel 24 sowie einen schwenkbaren Zangenschenkel 25 aufweist. Der schwenkbare Zangenschenkel 25 kann über die Kolbenzylindereinheit 26 aus der mit vollen Linien dargestellten Lage in die mit gestrichelten Linien dargestellte verschwenkt werden. Die Kolbenzylindereinheit 26 ist dabei mit dem Zangenrahmen 23 verbunden. Auf die Welle 19 ist ein Schwenkhebel 27 aufgeklemmt, dessen freies Ende mit der Kolbenstange 28 einer Kolbenzylindereinheit 29 verbunden ist, wobei letztere vom Tragarm 4 gehalten ist.A transverse support yoke 17 is welded to the lower end of the arm 4 and is connected at both ends to bearing plates 18. Two bearing plates are connected to each other by two shafts 19 and 20, the link 21 being placed on the shaft 20 and the link 22 on the shaft 19. The ends of the links 21 and 22 facing away from the shafts 19 and 20 carry a tong frame 23 which has a fixed tong leg 24 and a pivotable tong leg 25. The pivotable Zan g enschenkel 25 can be pivoted about the piston-cylinder unit 26 from the position shown with full lines to the position shown with dashed lines. The piston-cylinder unit 26 is connected to the tong frame 23. A pivot lever 27 is clamped onto the shaft 19, the free end of which is connected to the piston rod 28 of a piston-cylinder unit 29, the latter being held by the support arm 4.

Im Betrieb wird von einem Förderband 30 ein gefüllter Großsack 31 herantransportiert, dessen Öffnungsrand 32 durch die in der von der Anmelderin am 26.4.1984 einge-reichten Anmeldung beschriebene Vorrichtung bereits umgelegt und verschweißt worden ist. Dabei sind auf die Oberseite des Sackes durch die beschriebene Vorrichtung bereits zwei Klebstoffstreifen aufgetragen worden, die der Fixierung der umgele-gten und angedrückten Fahnen dienen.In operation, a conveyor belt 30 transports a filled large bag 31, the opening edge 32 of which has already been folded by that described in which a g by the Applicant on 26.04.1984 e-filed application device and welded. In this case, two strips of adhesive have already been applied to the top of the sack by the device described, which are used to fix the flipped and pressed flags.

Die diese Fahnen bildenden, seitlich überstehenden Bereiche 33 des umgelegten öffnungsrandes 32 sind dabei durch nicht dargestellte Führungsbleche gehalten und zwischen die festen Zangenschenkel 24 und die schwenkbaren Zangenschenkel 25 gefahren worden, wobei selbstverständlich die schwenkbaren Zangenschenkel 25 ihre geöffnete Stellung aufweisen müssen. Sobald dies geschehen ist, werden die Zangenschenkel 25 gegen die Zangenschenkel 24 geschwenkt und dadurch die seitlich überstehenden Bereiche 33 in den beiden Zangen festgeklemmt. Nachdem dies geschehen ist, werden die Andrückfinger 12 in die mit gestrichelten Linien dargestellte Lage abgesenkt. Im Anschluß daran werden die zangenrahmen 23 und damit auch die zugehörigen Zangenschenkel durch Betätigung der Kolbenzylindereinheiten 29 um die Wellen 19 und 20 aus ihrer mit vollen Linien dargestellten Lage in die mit gestrichelten Linien dargestellte verschwenkt, wobei die seitlich überstehenden Bereiche 33 nach innen auf die Kleberstreifen 34 aufgelegt und durch die festen Zangenschenkel 24 angepreßt werden. Aus der Figur ist zu erkennen, daß die Enden der schwenkbaren Zangenschenkel 25 Rollen 35 tragen, so daß sich während des Einlegevorgangs Material aus der Zange herausziehen kann. Nach dem Einlegevorgang werden die Zangenrahmen nach dem Abheben des Zangenschenkels 25 um die Wellen 19 und 20 in ihre mit vollen Linien dargestellte Lage zurückgeschwenkt, und zwar um den Winkel α. Da die Andrückfinger 12 nur einendig mit den verschiebbaren Rohren 11 verbunden sind, kann der Sack 31 dann durch Einschalten des Förderbandes 30 von den Fingern abgefahren werden. Der Sack 31 wird also in Richtung der freien Enden der Finger abtransportiert.The regions 33 of the folded-over opening edge 32 which form these flags and which protrude laterally are held by guide plates (not shown) and moved between the fixed tong legs 24 and the pivotable tong legs 25, the pivotable tong legs 25 of course having to have their open position. As soon as this has been done, the pliers legs 25 are pivoted against the pliers legs 24 and, as a result, the laterally projecting regions 33 are clamped in the two pliers. After this has been done, the pressure fingers 12 are lowered into the position shown with dashed lines. Subsequently, the pliers frame 23 and thus the associated pliers legs are pivoted by actuating the piston-cylinder units 29 about the shafts 19 and 20 from their position shown in full lines in the position shown in dashed lines, with the laterally projecting areas 33 inwards on the K liver strips 34 are placed and pressed by the fixed pliers legs 24. From the figure it can be seen that the ends of the pivotable pliers legs 25 carry rollers 35, so that material can pull out of the pliers during the insertion process. After the loading operation, the nipper frame after lifting the Zan be enschenkels g 25 around the shafts 19 and 20 in their illustrated with full lines pivoted back, namely by the angle α. Because the pressure fingers 12 are only connected at one end to the displaceable tubes 11, the sack 31 can then be moved from the fingers by switching on the conveyor belt 30. The sack 31 is thus removed in the direction of the free ends of the fingers.

Da nun aber die Füllguthöhe nicht immer gleich ist, wird diese durch eine nicht dargestellte Einrichtung abgetastet und entsprechend der tatsächlich festgestellten Füllguthöhe das Tragjoch 17 über Motor 7 und Seil 5 entsprechend angehoben bzw. abgesenkt. Da die Füllguthöhe.aber nur um einige Zentimeter differiert, ist der durch das Absenken des Tragjochs 17 über die Parallellenker bedingte geringe Seitenversatz der Zangen 24 ohne Nachteil für die Funktion.However, since the level of the product is not always the same, it is scanned by a device (not shown) and the support yoke 17 is raised or lowered accordingly via the motor 7 and cable 5 in accordance with the level of the product actually determined. Since the product height only differs by a few centimeters, the small lateral offset of the pliers 24 caused by the lowering of the support yoke 17 via the parallel link is without disadvantage for the function.
