PACKAGING MACHINE

Die Erfindung betrifft eine Verpackungsmaschine für Gegenstände wie Kataloge, Drucksachen, Zeitungen, Bücher od. dgl., die auf einer Transportstrecke eine Verpackungsstation durchlaufen, mit einer Plastikfolien-Bahn, vorzugsweise aus Polyäthylen, die der. Transportstrecke zuführbar ist und in die diese Gegenstände einwickelbar sind, so daß die Randbereiche der Bahn sich gegenseitig überlappen und daß die Gegenstände einer nachfolgenden Schweißstation zuführbar sind, welche Schweißvorrichtungen aufweist, mit der die Verpackung zuschweißbar und an den vorderen und hinteren Randbereichen der Gegenstände ab- und zuschweißbar ist.The invention relates to a packaging machine for items such as catalogs, printed matter, Newspapers, books or the like that have a packaging station on a transport route run through, with a plastic film web, preferably made of polyethylene, which the. Transport path can be fed and in which these objects can be wrapped, so that the Edge areas of the web overlap each other and that the objects of a subsequent Welding station can be fed, which has welding devices with which the packaging can be welded and on the front and rear edge areas of the objects can be removed and welded.

Bei Vorrichtungen dieser Art ist es bekannt, die Verpackung längs der Vorderkante und der Hinterkante des Gegenstands zusammenzuschweißen, während die "längs verlaufenden Uberlappungsbereiche nicht zusammengeschweißt werden. Dies rührt von Schwierigkeiten her, die auftreten, wenn man dünne Plastikfolien zusammenschweißen muß, deren Dicke seifen 0,030 mm übersteigt, und weil dieses Zusammenschweißen während des TransportsIn devices of this type, it is known that the packaging along the leading edge and welding together the trailing edge of the object, while the "longitudinal Overlapping areas are not welded together. This comes from difficulties that occur when thin plastic films have to be welded together, their thickness soap exceeds 0.030 mm, and because of this welding together during transport

dieser Gegenstände längs einer Transferstrecke stattfinden muß. Dies trifft insbesondere dann ZU7 wenn die Transportgeschwindigkeit relativ groß ist und wenn die Oberseite des Gegenstands in denjenigen Bereichen uneben ist, die unterhalb des Überlappungsbereichs der Verpackung liegen.these objects must take place along a transfer path. This applies in particular to 7 when the transport speed is relatively high and when the top of the object is uneven in those areas that are below the overlap area of the packaging.

Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, mit der man auch unter den oben genannten Bedingungen die Überlappungsbereiche der Verpackung zuverlässig zuschweißen kann. Die Verschweißung soll dabei genügend stark sein , ohne daß man das Risiko eingehen muß, daß die Plastikfolie im Augenblick des Schweißvorganges anbrennt. Insbesondere soll erreicht werden, daß die erfindungsgemäße Vorrichtung eine hohe Fördergeschwindigkeit erlaubt, ohne daß dies sich in einer weniger starken und zuverlässigen Verschweißung niederschlägt.The object of the invention is to provide a device with which one can also use the The above-mentioned conditions reliably weld the overlapping areas of the packaging can. The weld should be strong enough without that The risk must be taken that the plastic film will burn at the moment of the welding process. In particular, it should be achieved that the device according to the invention has a high conveying speed allowed without this being reflected in a less strong and reliable weld.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß mindestens eine der Schweißvorrichtungen der Schweißstation eine Rolle umfasst, die mindestens einen elektrischen Widerstand an deren Umfang aufweist, daß die unter der Rolle hindurchlaufenden Gegenstände die Rolle antreiben und zwar über den oben liegenden Randbereich der Bahn, der in Wirkungsverbindung mit dem Widerstand ist, daß der Widerstand mit eher elektrischen Energiequelle verbunden ist, die den Widerstand auf eine Temperatur aufheizt, bei der Teile des oben liegenden Randbereichs , welche am Widerstand anliegen, zuverlässig an den darunterliegenden Randbereich angeschweißt werden.According to the invention, this object is achieved in that at least one of the welding devices the welding station comprises a roller which has at least one electrical resistance on its periphery that the objects passing under the roller drive the roller over the overhead edge area of the web, which is in operative connection with the resistance, that the resistance with more electrical Energy source is connected, which heats the resistor to a temperature at which Parts of the upper edge area, which are in contact with the resistor, reliably be welded to the underlying edge area.

Man kann so mit dem Elektromagneten 37 den Arm 22 anziehen, so daß die Gabel 20 und die Rolle 17 von der Verpackungsfolie abgehoben werden, wenn die Maschine stoppt.An electromagnet 37 or the like is provided fixed to the frame on the machine. This is connected to an electrical .Energiequelle, not shown, with the help of lines 38, 39. You can attract the arm 22 with the electromagnet 37, so that the fork 20 and the roll 17 are lifted from the packaging film when the Machine stops.

Um das Risiko auszuschalten, daß sich keine vollständige Trennung zwischen den Katalogen.2 ergibt, wenn man Plastikfolie mit bestimmten Eigenschaften verwendet - in anderen Worten: Um zu verhindern, daß die Verpackung unerwünschten Kräften ausgesetzt wird, wenn das Schweißen mit Hilfe der Rolle 17 auftritt, hat man der Schweißbrücke 15 eine besondere Gestaltung gegeben. Diese umfasst einen senkrecht bewegbaren Arm 40, der so angetrieben ist, daß er nach unten geht, sobald ein Katalog 2 durchgelaufen ist. Erfindungsgemäß hat der Arm 40 drei Parallelwiderstandsschienen 41, 42, 43, die in der gleichen Weise erhitzt werden , wie der Widerstandsdraht 24 der Rolle 17. Die beiden äußeren Parallelwiderstands-In order to avoid the risk that there is no complete separation between the catalogs. 2 results if you use plastic film with certain properties - in other words: To prevent the packaging from being subjected to undesirable forces when the Welding occurs with the aid of the roller 17, the welding bridge 15 has a special one Design given. This comprises a vertically movable arm 40 which is driven in this way is that it goes down as soon as a catalog 2 has gone through. According to the invention has the arm 40 has three parallel resistance rails 41, 42, 43 which are heated in the same way like the resistance wire 24 of the roller 17. The two outer parallel resistance

Dies kann dazu führen, daß die überlappenden Bereiche voneinander getrennt werden, wenn der Katalog 2 die Rolle 17 erreicht. Um dies auszuschalten, hat die Verpackungsstation E der Maschine mindestens einen nicht dargestellten Behälter, der so angeordnet ist, daß man von ihm aus Flüssigkeit auf die Oberseite desjenigen der überlappenden Randbereiche 13, bringen kann, auf dem der andere Randbereich aufliegt. Die aufgebrachte Flüssigkeit hält die Schichten aufgrund der Oberflächenspannung bis zu demjenigen Zeitpunkt aneinander fest, zu dem sie verschweißt werden. Eine besonders gut für diese Zwecke geeignete Flüssigkeit ist eine Mischung von etwa 50 Volumenprozent Äthylen-Monoäfher und Spiritus (denaturierter Alkohol).This can lead to the overlapping areas becoming separated from each other when Catalog 2 reaches roll 17. To switch this off, the packaging station E the machine at least one container, not shown, which is arranged so that one from it from liquid to the top of that of the overlapping edge areas 13, can bring, on which the other edge area rests. The applied liquid holds the layers due to the surface tension to each other up to that point in time firmly to which they are welded. A liquid that is particularly suitable for this purpose is a mixture of about 50 percent by volume ethylene mono-ether and alcohol (denatured alcohol).

Wenn Adressaufkleber verwendet werden sollen, so ist es wesentlich, daß diese in der Verpackungsstation nicht gefaltet werden, so daß die Verschweißung der überlappenden Randbereiche 13, 14 nicht gestört wird. Es ist auch wichtig, daß die Adresszeftel während des Verpackungsvorgangs oder des Schweißvorganges nicht unten zu liegen kommen und durch Reklameaufdrucke auf der Verpackung verdeckt werden. Zu diesem Zweck hat die drehbare Blattzufuhrvorrichtung der Station D eine nicht dargestellte Vorrichtung, mit der man einen Klebstoffstreifen auf dem Auftragszettel anbringen kann , so daß der Adresszettel in einer bestimmten Lage festgehalten wird und flach gehalten wird, nachdem er auf dem Auftragszettel oder der Außenseite des Katalogs angebracht worden ist. If address labels are to be used, it is essential that they be in the packaging station are not folded, so that the welding of the overlapping edge regions 13, 14 is not disturbed. It is also important that the address mark is kept during the Packaging process or the welding process do not come to rest and through Advertising imprints on the packaging can be covered. For this purpose the rotatable Sheet feeding device of the station D a device, not shown, with which one Adhesive strips can be attached to the order slip, so that the address slip in a in a specific location and held flat after being affixed to the order slip or the outside of the catalog.

Schließlich ist es wichtig, daß die Kataloge 2 einen bestimmten Absfand voneinander einhalten, wenn sie die Schweißsfation F erreichen, und es ist deshalb wichtig, daß die Kataloge 2 in diesem Abstand zueinander bleiben, wenn sie vom Förderband 9 kommend vom Förderband 10 übernommen werden . Um diese Bedingung zu erfüllen, liegt dasFinally, it is important that the catalogs 2 have a certain distance from each other when they reach welding station F, and it is therefore important that the Catalogs 2 remain at this distance from one another when they come off the conveyor belt 9 be taken over by the conveyor belt 10. In order to meet this condition, that lies

Soweit oben die unterschiedlichen Stationen der Maschine nicht genau beschrieben worden sind, besitzen sie die bekannte Gestalt und Funktion. Gleichermaßen wurde die Verpackungsstation nicht besonders beschrieben, da diese in zahlreichen Arten abgewandelt werden kann.As far as the different stations of the machine have not been described in detail above are, they have the familiar shape and function. The packing station became the same not specifically described as this can be modified in numerous ways.

Der wendelförmig gewundene Widerstapdsdraht 24 der Rolle 17 kann auch einen Widerstandsdraht anderer Gestalt haben. Man könnte z. B. auch einen Profilring kreisförmigen, quadratischen oder rechteckigen Querschnitts verwenden. Darüber hinaus könnte der Elektromagnet 37 durch eine mechanische Hubvorrichtung geeigneter Art ersetzt werden. Die Rolle 17 kann auch mit ihrem eigenen Gewicht auf die Kataloge 2 drücken und wenn die Rolle 17 leer läuft, dann könnte die Gabel 20 auf einer Stütze ruhen, die in geeigneter Weise in senkrechter Richtung einstellbar ist.The helically wound resistance wire 24 of the roller 17 can also have a resistance wire of another shape. One could e.g. B. also a profile ring circular, use a square or rectangular cross-section. In addition, the electromagnet could 37 can be replaced by a mechanical lifting device of a suitable type. The roller 17 can also press on the catalogs 2 with its own weight and if the Roll 17 runs idle, then the fork 20 could rest on a support that is suitable Way is adjustable in the vertical direction.
