Description

3030th

Die Erfindung betrifft eine Verpackungsmaschine mit Schweiß- und Schneidstation nach dem Oberbegriff des Patentanspruchs.The invention relates to a packaging machine with a welding and cutting station according to the preamble of Claim.

Eine Verpackungsmaschine der genannten Art ist aus der US-PS 29 82 066 bekannt. Bei dieser Verpackungsmaschine ist einer der Schweißbacken tragenden Blöcke in einer in dem anderen Block ausgebildeten länglichen öffnung gleitend aufgenommen. Beim Betrieb der Schneid- und Schweißstation führen beide Blöcke gegenläufige Kreisbewegungen aus, in deren Verlauf -to der aufgenommene Block relativ zu dem aufnehmenden Block in Längsrichtung von dessen Öffnung hin- und herbewegt wird, wobei die Längsränder der Öffnung geradlinige Führungsflächen bilden.A packaging machine of the type mentioned is known from US Pat. No. 2,982,066. With this packaging machine is one of the jaw-carrying blocks in an elongated one formed in the other block Opening added sliding. When operating the cutting and welding station, both blocks lead counter-rotating circular movements, in the course of which -to the recorded block relative to the receiving Block is reciprocated in the longitudinal direction of its opening, the longitudinal edges of the opening form straight guide surfaces.

Bei diesem Konstruktionsprinzip sind die bewegten Massen groß, weil der aufnehmende Block groß im Vergleich zu dem aufgenommenen Block ausgebildet ist.With this design principle, the moving masses are large because the receiving block is large in size Compared to the recorded block is formed.

Aus der DE-OS 22 24 726 ist eine Schweiß- und Schneidstation für eine Verpackungsmaschine bekannt, bei der Schweißbacken tragende Blöcke ebenfalls gegenläufig Kreisbewegungen ausführen. Die Blöcke sind auf vertikalen Führungsstangen geführt, die mitbewegt werden müssen. Zwar sind bei dieser Schweiß- und Schneidstation die beiden Blöcke im wesentlichen gleichgroß ausgebildet, jedoch ergeben ^ sich große bewegte Massen durch die Mitbewegung der Führungsstangen.From DE-OS 22 24 726 a welding and cutting station for a packaging machine is known in which blocks carrying welding jaws also perform circular movements in opposite directions. The blocks are guided on vertical guide rods that have to be moved with them. Although in this cutting and welding station, the two blocks are substantially equal in size, but ^ arise large moving masses by the co-movement of the guide rods.

Aufgabe der Erfindung ist es, die Einrichtung zur Führung der Schweißbacken so auszubilden, daß die bewegten Massen möglichst klein gehalten werden.The object of the invention is to design the device for guiding the welding jaws so that the moving masses are kept as small as possible.

Diese Aufgabe v/ird durch die im kennzeichnenden Teil des Patentanspruchs angegebenen Merkmale gelöst.This task is accomplished by the features indicated in the characterizing part of the patent claim solved.

Die bewegten Massen können bei der erfindungsgemäßen Verpackungsmaschine dadurch klein gehalten werden, daß die erfindungsgemäßen Blockpaare, von denen jedes aus einem, eine Schweißbacke tragenden Block und aus einem weiteren Block besteht, in einer fixierten Führung gefuhrt und die Blockpaare gleichgroß und mit jeweils kleiner Masse ausgebildet werden können.The moving masses can thereby be kept small in the packaging machine according to the invention be that the block pairs according to the invention, each of which consists of a welding jaw supporting Block and consists of another block, guided in a fixed guide and the block pairs are the same size and each can be designed with a small mass.

Die in F i g. 1 dargestellte und im folgenden kurz beschriebene Verpackungsmaschine 10 führt die notwendigen Form-, Abfüll- und Schweißvorgänge durch. Zu \ erpackende Gegenstände P werden durch einen Förderer 12 bewegt, der eine Anzahl von in gleichen Abständen angeordneten Mitnehmern 14 umfaßt, deren Zwischenräume durch die Größe der Gegenstände bestimmt sind. Der Förderer bewegt sich um eine vordere und eine hintere Rolle 16 und 18. Die Rolle 18 wird durch einen Antriebszug angetrieben, so daß das obere Trumm des Förderers 12 in Richtung des Pfeiles A bewegt wird. Wenn die Gegenstände vorrücken, gelangen sie in einen Bahnmaterial-Formkasten 20, der Bahnmaterial 22 formt, das von einer Rolle 24 abgezogen wird, die auf einer Achse 26 eines Rollengestells 28 angeordnet ist. Das Bahnmaterial wird schlauchförmig zusammengelegt, so daß jeder Gegenstand innerhalb eines schlauchförmigen Bahnmaterials 22A liegt. Die seitlichen Kanten des Bahnmaterials werden nach unten durch den Formkasten 20 umgefaltet und zwischen beheizten, in Längsabstand liegenden Paaren von Schweißrändern 30 und 32 aufgenommen. Alternativ kann nur ein Paar Schweißräder, beispielsweise die Schweißräder 32 verwendet werden, während das andere Paar der Schweißräder 32 eine Form aufweisen kann, die zum Falten der nach unten weisenden Längskanten zur Seite und nach oben in Richtung des schlauchförmigen Bahnmaterials 22,4 dient. Die in dem Schlauch eingehüllten Gegenstände rücken zu einer quergerichteten Schweiß- und Schneidstation 34 vor, welche Schweiß- und Schneidbacken 36 umfaßt, die zugleich die Schweiß- und Schneidbacken 36 in Richtung der Bahn und zurück bewegt und die Bahn zwischen den Gegenständen unter Druck erfaßt und damit jeden Gegenstand in einem Abschnitt des schlauchförmigen Bahnmaterials hermetisch einschließt. Packungen PK, die auf diese Weise gebildet werden, werden auf einen Förderer 38 über eine Rinne 40 überführt.The in F i g. 1 shown and briefly described below performs the necessary forming, filling and welding operations. Objects P to be packed are moved by a conveyor 12 which comprises a number of drivers 14 which are arranged at equal intervals and the spaces between which are determined by the size of the objects. The conveyor moves around a front and a rear roller 16 and 18. The roller 18 is driven by a drive train, so that the upper run of the conveyor 12 is moved in the direction of arrow A. As the articles advance, they enter a sheet material forming box 20 which forms sheet material 22 that is withdrawn from a roll 24 mounted on an axis 26 of a roll cage 28. The sheet material is collapsed into a tubular shape so that each article lies within a tubular sheet material 22A . The lateral edges of the web material are folded over downward through the molding box 20 and received between heated, longitudinally spaced pairs of welding edges 30 and 32. Alternatively, only one pair of welding wheels, for example welding wheels 32, can be used, while the other pair of welding wheels 32 can have a shape which serves to fold the downwardly pointing longitudinal edges to the side and upward in the direction of the tubular web material 22.4. The articles encased in the tube advance to a transverse welding and cutting station 34 which includes welding and cutting jaws 36 which simultaneously move the welding and cutting jaws 36 in the direction of the path and back and engages and pressurizes the path between the objects in order to hermetically enclose each article in a portion of the tubular sheet material. Packages PK that are formed in this way are transferred onto a conveyor 38 via a chute 40.

Die Schweiß- und Schneidstation 34 ist mit einem vereinfachten und anpassungsfähigen Antriebszug versehen, der eine Anpassung an einen größeren Abmessungsbereich von Gegenständen (Höhe undThe welding and cutting station 34 is provided with a simplified and adaptable drive train, the adaptation to a larger range of dimensions of objects (height and

Länge) gestattet und beim Schweißen der Bahn dennoch eine gleiche oder im wesentlichen gleiche Geschwindigkeitsanpassung zwischen der Bahn und den Schweißbacken gestattet Der Antrieb für die Schweiß- und Schneidbacken 36 in kreisförmigen Bahnen oberhalb und unterhalb des schlauchförmigen Bahnmaterials 22A, und die das Bahnmaterial erfassenden Oberflächen der Schweiß- und Schneidbacken 36 sind einander während des ganzen Betriebszyklus zugewandt Diese Arbeitsweise gestattet geringere Abstände zwischen den Gegenständen, da die Schweiß- und Schneidbacken 36 beim Heranführen, Schweißen und Zurückziehen von der schlauchförmigen Bahn die geringsten Abmessungen (Breite der Schweißbacken) gegenüber den Bahnbereichen zwischen den Gegenständen bieten.The drive for the welding and cutting jaws 36 in circular paths above and below the tubular web material 22A, and the web material engaging surfaces of the Welding and cutting jaws 36 are facing each other during the entire operating cycle.This mode of operation allows smaller distances between the objects, since the welding and cutting jaws 36 have the smallest dimensions (width of the welding jaws) compared to the areas of the path when they are brought up, welded and withdrawn from the tubular web offer the objects.

Dazu umfaßt der Antrieb für eine Schweiß- und Schneidbacke eine Halterung, die zugleich die Schweiß- und Schneidbacken 36 translatorisch in einer waagerechten und senkrechten Richtung verschiebt, die im folgenden zur Vereinfachung als X- und V-Richtung bezeichnet werden sollen. Dies geschieh* mit Hilfe von nockengesteuerten Elementen, die relativ in einer .-,senkrechten Richtung beweglich sind.For this purpose, the drive for a welding and cutting jaw includes a holder which at the same time translates the welding and cutting jaws 36 in a horizontal and vertical direction, which are hereinafter referred to as the X and V directions for the sake of simplicity. This is done * with the help of cam-controlled elements that are relatively movable in a perpendicular direction.

Gemäß F i g. 2 umfaßt die Schweiß- und Schneidstation 34 senkrechte, in seitlichem Abstand liegende Seitenrahmenteile 42, die durch obere und untere Träger 44 miteinander verbunden sind. Die Seitenrahmenteile 42 tragen drehbar obere und untere, quergerichtete Antriebswellen 46 und 48, auf deren eines Ende jeweils Zahnräder 50 und 52 aufgekeilt sind. Die Antriebswelle 48 bildet die Eingangswelle, und ist mit dem Antriebszug der Maschine über eine Kette 54 und ein Kettenrad 56 verbunden, das ebenfalls auf die Antriebswelle 48 aufgekeilt ist. Die Antriebswelle 48 ist mit der Antriebswelle 46 mit Hilfe von Zahnrädern 58 und 60 verbunden, die auf kurze Achsschäfte 62 und 64 drehbar aufgesetzt sind.According to FIG. 2, the welding and cutting station 34 comprises vertical, laterally spaced apart Side frame parts 42 which are connected to one another by upper and lower beams 44. The side frame parts 42 rotatably carry upper and lower transverse drive shafts 46 and 48 on their gears 50 and 52 are keyed at one end. The drive shaft 48 forms the input shaft, and is connected to the drive train of the machine by a chain 54 and a sprocket 56, which is also connected to the Drive shaft 48 is keyed. The drive shaft 48 is connected to the drive shaft 46 with the aid of gears 58 and 60 connected, which are rotatably mounted on short shafts 62 and 64.

Jede der Antriebswellen 46 und 48 trägt eine flache, kreisförmige Platte 66,67. Die Mittelpunkte der Platten 66, 67 liegen exzentrisch in bezug auf die Achsen der Antriebswellen 46 und 48, die Platten dienen daher als Nocken, wie im folgenden erläutert werden soll.Each of the drive shafts 46 and 48 carries a flat, circular plate 66,67. The centers of the plates 66, 67 are eccentric with respect to the axes of the drive shafts 46 and 48, the plates therefore serve as Cams, as will be explained below.

Wie aus F i g. 7 hervorgeht, weist jedes Seitenrahmenteil 42 eine senkrechte Schwalbenschwanznut 68 auf, die durch einen waagerechten, rechtwinkligen Schlitz 70 in obere und untere Bereiche 72,74 unterteilt ist. Jeder Bereich 72, 74 nimmt einen von zwei im wesentlichen rechtwinkligen Blöcken 76, im folgenden als weitere Blöcke bezeichnet, auf, die jeweils mit Schwalbenschvanzführungen 78 versehen sind, so daß die Blöcke gleitend in den Bereichen 72 und 74 laufen.As shown in FIG. 7, each side frame portion 42 has a vertical dovetail groove 68 on, which is divided by a horizontal, right-angled slot 70 into upper and lower areas 72,74 is. Each area 72, 74 takes one of two generally rectangular blocks 76, hereinafter referred to as further blocks, each provided with dovetail guides 78 so that the blocks slide in areas 72 and 74.

In jedem weiteren Block 76 befindet sich eine Öffnung 80 die als berührungsfreier Durchgang für die Antriebswelle 46 dient. Jeder Block 76 weist weiterhin eine Schwalbenschwanznut 82 senkrecht zu der Schwalbenschwanznut 68 auf. Die Schwalbenschwanznut 82 dient zur gleitenden Aufnahme eines kleineren, die Schweißbacken tragenden Blockes 84 mit einer Öffnung 86, die gleitend eine der Platten 66 aufnimmt. Ansätze 88 an den Blöcken 84 dienen als Stützflächen für einen Schweißbalkenträger.In each further block 76 there is an opening 80 which acts as a contact-free passage for the Drive shaft 46 is used. Each block 76 further has a dovetail groove 82 perpendicular to that Dovetail groove 68. The dovetail groove 82 is used to slide a smaller, the block 84 supporting the welding jaws having an opening 86 which slidably receives one of the plates 66. Lugs 88 on blocks 84 serve as support surfaces for a welding beam support.

Die oben erläuterte Konstruktion führt gemäß F i g. 2, 4 und 5, die die quergerichtete Schweiß- und Schneidstation 34 in verschiedenen Betriebsstellungen zeigen, folgende Arbeitsgänge durch. Fig.2 zeigt die Schweiß- und Schneidbacken 36 in der am weitesten getrennten Stellung. Die weiteren Blöcke 76 beider Seltenrahmenteile 42 weisen ihren maximalen Absland auf, während die Blöcke 84 in bezug auf die entsprechenden weiteren Blöcke 75 zentriert sind (F i g. 4). Wenn sich die Antriebswellen 46 und 48 aus der Position der Fig.2 und 4 in die Position der Fig.5 drehen, bewegen sich die Schweiß- und Schneidbacken 36 aufeinander zu, und die Blöcke 76 und 84 führen eine Relativbewegung aus. Gleichzeitig gleiten die weiteren Blöcke 76 in den Schwalbenschwanznuten 68 aufeinander zu. Während sich die Antriebswellen 46, 48 drehen, bewirken die exzentrischen, kreisförmigen Platten 66 zugleich eine Bewegung aller weiteren Blöcke 76 nach unten für die obere Schweißbacke und nach oben für die untere Schweißbacke und eine waagerechte Bewegung der Blöcke 84. Wenn die Schweißstangen in Druckberührung stehen (Fig.5) und die Bahn schneiden und schweißen haben sich die weiteren Blöcke 76 aufeinander zubewegt und die Blöcke 84 liegen zentrisch in bezug auf die weiteren Blöcke 76.The construction explained above leads according to FIG. 2, 4 and 5 show the transverse welding and cutting station 34 in various operating positions show the following operations. Fig.2 shows the Welding and cutting jaws 36 in the most separated position. The other blocks 76 of both Rare frame parts 42 have their maximum Absland, while the blocks 84 with respect to the corresponding further blocks 75 are centered (FIG. 4). When the drive shafts 46 and 48 move out of the Position of Fig. 2 and 4 in the position of Fig. 5 rotate, the welding and cutting jaws 36 move towards each other, and the blocks 76 and 84 guide a Relative movement. At the same time, the further blocks 76 slide on one another in the dovetail grooves 68 to. As the drive shafts 46, 48 rotate, the eccentric circular plates 66 operate at the same time a movement of all further blocks 76 downwards for the upper welding jaw and upwards for the lower welding jaw and a horizontal movement of blocks 84. When the welding rods are in pressure contact stand (Fig.5) and cut and weld the path, the other blocks 76 have to one another moved closed and the blocks 84 are centered with respect to the further blocks 76.

Fig.8 zeigt eine bevorzugte Ausführungsform der exzentrischen Antriebe der Schweiß- und Schneidbakken 36. Jeder Nocken oder jede exzentrische Platte 66, 67, die in Fig.8 mit 66a bezeichnet ist, weist eine exzentrische Bohrung 666 auf, die gleitend einen Exzenter 69 aufnimmt, der einstellbar auf der Antriebswelle 46 angebracht ist. Die relative Position der Exzenter 66a und 69 ist so gewählt, daß sich eine Exzentrizität e-2 ergibt. Dies ist die maximal erzielbare Exzentrizität. Die kleinste Exzentrizität stellt sich ein, wenn die exzentrische Platte 67 um 180° gedreht wird. In diesem Falle ergibt sich eine Exzentrizität e-1. Die relative Position der Exzenter 66a und 69 kann mit Hilfe von Einstellschrauben oder dergleichen festgelegt werden.Fig.8 shows a preferred embodiment of the eccentric drives of the welding and cutting jaws 36. Each cam or each eccentric plate 66, 67, which is designated in Figure 8 with 66a, has an eccentric bore 666, the sliding one Eccentric 69 accommodates which is adjustably mounted on the drive shaft 46. The relative position of the Eccentrics 66a and 69 are chosen so that an eccentricity e-2 results. This is the maximum achievable Eccentricity. The smallest eccentricity occurs when the eccentric plate 67 is rotated through 180 °. In this case, an eccentricity e-1 results. The relative position of the eccentrics 66a and 69 can with the help be set by adjusting screws or the like.

Durch den Aufbau der Schweiß- und Schneidstation 34 ergibt es sich daher, daß die oberen und unteren Schweißbacken eine konstante Orientierung beibehalten und daß die das Bahnmaterial erfassenden Flächen der Schweißbacken oder Klauen stets einander zugewandt sind. Daher nähern sich die Schweißbacken dem schlauchförmigen Bahnmaterial und entfernen sich von diesem zwischen den in Längsabstand liegendenThe structure of the welding and cutting station 34 therefore results in the upper and lower Welding jaws maintain a constant orientation and that the surfaces engaging the web material the welding jaws or claws are always facing each other. Therefore, the welding jaws approach the tubular web material and move away from this between the longitudinally spaced
