Die so ralt den Bodenquerschweißnähten versehene Folienschlauchbahn wird einer Querschneideeinrichtung zugeführt, mit deren Hilfe die einzelnen Beutelabschnitte abgetrennt werden. Die Folienschläuche haben die Neigung, an der Schnittstelle als Folge des Abschneidvorganges mit ihren Öffnungsrändern zusammenzuhaften, so daß sie sich beim späteren Füllvorgang fiefllechtt öffnen lassen. Soweit bei der Herstellung kleinerer Beutel diese mit entgegengesetzter Richtung ihtr- Öftnungsränder hergestellt und abgetrennt werdetl, kommen diese Folienbeutel auch bei der Ablage mit ihren Offnungsrändern entgegengesetzt zu liegen, was für die Stapelung der Folienbeutel unbequem und unerwünscht ist. beck der Erfindung ist die Beseitigung dieser Nachteile. Erreicht wird das dadurch, daß bei einer Maschine der vorerwähnten Art im Anschluß an die Abtrennungsvorrichtung der einzelnen Schlauchabschnitte vor der Folienschlauchbahn im Bereich beiderseits der Schlauchabschnitte auf diese Abschnitte einwirkende Führungs- und Transportmittel t'tn Öffnen der nicht verschweißten Öffnungsränder der einzelnen Schlauchabschnitte und anschließend ia diese Führungs- und Transportmittel Halte- und Transportmittel zum Transport der einzelnen Schlauch-Abschnitte zu einer Stapelungsvorrichtung vorgesehen nd, in welcher die Beutel in übereinstimmender ge ihrer Öffnungsränder zur Ablage kommen. Im weiteren Verfolg der Erfindung sind in die endlose Bahn der Halte- und Transportmittel beim Abtrennen von an den Schlauchabschnittöffnungsrändern und art den Bodenschweißnahträndern zusammenhängenden Schlauchabschnitten in Hintereinanderfolge zwei Anlagen für die Schlauchabschnitte eingeschaltet, die abwechselnd die abzulegenden Schlauchabschnitte zuot erhalten, wobei die Zuführung der zweiten ablage entgegengesetzt zur Zuführung der ersten Ablage erfolgt, so daß die Schlauchabschnitte in jedem Ablagestapel gleichgerichtet zur Ablage loamen. tJ'n der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung schematisch dargestellt.Machine for the production of bags from a film tube made of thermoplastic Plastic The invention relates to a machine for producing bags from weldable, Foil tubes guided over a rotating cylinder, the transversely directed Bottom welding points in the middle of a lowerable and liftable sealing bar in continuous Operation to be carried out. The so provided with the bottom cross-weld seams Tubular film web is fed to a cross-cutting device, with the help of which the individual bag sections are separated. The foil tubes have the Inclination at the interface as a result of the cutting process with their opening edges to stick together so that they can be opened braided during the later filling process. So much for the production of smaller bags, these with the opposite direction These foil bags come from their opening edges also to lie opposite when filing with their opening edges, what for the stacking of the foil bags is inconvenient and undesirable. beck of the invention is the elimination of these disadvantages. This is achieved by having one machine of the aforementioned type following the device for separating the individual tube sections in front of the tubular film web in the area on both sides of the tubular sections on this Sections affecting guide and transport means t'tn open the not welded Opening edges of the individual hose sections and then generally this guide and transport means holding and transport means for transporting the individual hose sections nd provided to a stacking device in which the bags in matching ge their opening edges come to the storage. In the further pursuit of the invention are into the endless path of the holding and transport means when separating from the tube section opening edges and type of hose sections connected to the bottom weld seam edges in succession two systems are switched on for the hose sections, which alternate the ones to be deposited Get hose sections zuot, with the supply of the second tray opposite to feed the first tray takes place, so that the hose sections in each Loam the discard pile in the same direction as the discard. The drawing is an exemplary embodiment of the subject matter of the invention shown schematically.
Es zeigt Abb. 1 eine Ausführungsform der Maschine in Seitnansicht, Abb. 2. die gleiche Maschine in Draufsicht, Abb 3 einen Folienschlauchstreifen mit kurzen Schlauchstücken für kurze Beutel.Fig. 1 shows an embodiment of the machine in a side view, Fig. 2. the same machine in plan view, Fig. 3 with a tubular film strip short pieces of tubing for short bags.
In Abb. 1 und 2 ist die Folienschlauchbahn gezeigt, wie sie über Walzen 2 dem Führungszylinder 3 für die Durchführung der Beutelbodennahtschweißung zugeführt wird. Die federnd gegen den Führungszylinder 3 gepreßten Zugringe 4 transportieren die Folienschlauchbahn 1 und halten sie gleichzeitig beiderseits der Schweißstelle straff am Zylinder 3. Die geheizte Schweißleiste 5 ist an einem Schwenkhebel 11 angebracht und wird durch nicht dargestellte, bekannte Mittel beim Beginn des Schweißvorganges auf den Umfang des Zylinders 3 gesenkt, um nach Beendigung des Schweißvorganges wieder abgehoben zu werden. Außerdem ist an dem Schwenkhebel 11 ein hitzebeständiges Gewebe 6 zwischen zwei Traderen 7 gespannt, von denen die eine Traverse 7 arehbar angeordnet und dem Einfluß einer Torsionsspannfeder ausgesetzt ist. Dieses Gewebe legt sich vor dem Beginn des Schweißvorganges fest auf die Folienschlauchbahn 1 und preßt diese fest gegen den Umfang des Zylinders 3. Gleichzeitig werden durch eine Kurvenscheibe 8 über einen Steuerhebel 9, eine Kuppelstange 10 und den schwenkbaren Traghebel 11 das Gewebe 6 und die alsdann auch gegen das Geweben und den Umfang des Zylinders 3 gepreßte Sehweißleiste 5 in Laufrichtung der Folienschlauchbahnl auf dem Folienschlauchzylinder3 mit der gleichen Geschwindigkeit wie diese vorwärts bewegt, so daß die Schweißung auf einem verhältnismäßig langen Weg durchgeführt wird. In Fig. 1 and 2 the tubular film is shown how it is over Rollers 2 the guide cylinder 3 for carrying out the bag bottom seam welding is fed. Transport the pull rings 4, which are pressed resiliently against the guide cylinder 3 the tubular film web 1 and hold it at the same time on both sides of the weld taut on the cylinder 3. The heated sealing bar 5 is on a pivot lever 11 attached and is by not shown, known means at the beginning of the welding process lowered to the circumference of the cylinder 3 to after completion of the welding process to be picked up again. In addition, a heat-resistant one is on the pivot lever 11 Tissue 6 stretched between two traders 7, one of which traverse 7 can be accessed arranged and exposed to the influence of a torsion tension spring. This tissue lies firmly on the tubular film web 1 before the start of the welding process and presses it firmly against the circumference of the cylinder 3. At the same time, through a cam 8 via a control lever 9, a coupling rod 10 and the pivotable Carrying lever 11 the fabric 6 and then also against the fabric and the circumference of the cylinder 3 pressed welding strip 5 in the running direction of the tubular film on the film tube cylinder 3 at the same speed as this forward moved so that the weld carried out on a relatively long way will.
Nach beendeter Schweißung werden die Schweißleiste 5 und das Gewebe 6 am Traghebel 11 - durch besondere Einrichtungen von der Folienschlauchbahn 1 abgehoben und durch die Kurvenscheibe 8 in ihre Ausgangsstellung zurückgeschwenkt. Die mit Bodenschweißnaht versehene Folienschlauchbahn 1 wird danach über die Walzen 12 dem Zugwalzenpaar 13, 14 zugeführt. Damit ein sicherer Transport der Folienschlauchbahn 1 gewährleistet ist, sind vor dem Schneidwerk 15 zwischen diesem und dem Zugwalzenpaar 13, 14 sowie hinter dem Schneidwerk 15 zwischen diesem und der Transportwalze 16 Bandleitungen 17 vorgesehen. After the welding is finished, the sealing bar 5 and the fabric 6 on the support lever 11 - through special facilities from the tubular film track 1 lifted off and swiveled back into its starting position by the cam 8. The tubular film web 1 provided with a bottom weld seam is then passed over the rollers 12 fed to the pair of draw rollers 13, 14. This ensures safe transport of the tubular film web 1 is guaranteed, are in front of the cutting unit 15 between this and the pair of draw rollers 13, 14 and behind the cutting unit 15 between this and the transport roller 16 Ribbon lines 17 are provided.
Das Zugwalzenpaar 13, 14 transportiert die Folienschlauchbahn 1 zum Schneidwerk 15, welches die einzelnen Beutel 18 in der jeweiligen Länge abtrennt. The pair of pulling rollers 13, 14 transports the tubular film web 1 to Cutting unit 15, which separates the individual bags 18 in the respective length.
Kurz bevor die Schnittstelle die mittels Hebel 35, Rolle36, Nockenscheibe37} Feder- oder Gewichtsbeeinflussung auf und ab bewegten Rollen 19 gegenüber der Transportwalze 16 passiert, senken sich diese sogenannten hüpfenden Rollen 19 auf die Walze 16 und machen unter dem Einfluß maschinell gesteuerter Seitenführungseinrichtungen, wie z. B. exzentrischer Kurvenführungen od. dgl., gleichzeitig eine Bewegung quer zur Förderrichtung der abgetrennten Beutel 18, damit sich die Beutelöffnungsränder an der Schnittstelle voneinander lösen.Shortly before the interface is activated by means of lever 35, roller36, cam disk37} Spring or weight influencing up and down rollers 19 relative to the transport roller 16, these so-called hopping rollers 19 are lowered onto the roller 16 and make under the influence of machine-controlled lateral guiding devices, such as B. eccentric cam guides od. Like., At the same time a movement across to the conveying direction of the separated bags 18, so that the bag opening edges detach from each other at the interface.
Werden kurze Beutel 18 hergestellt, so können diese mit den Bodenschweißnähten 38, 39 und den Öffnungsrändem 40, 41 jeweils nebeneinanderliegend erzeugt und in der Mitte der breiter oder dicht nebeneinander mit je zwei Schweißnähten hergestellten Schweißstellen und in der Mitte der dazwischenliegenden Folienschlauchlängen voneinander getrennt werden (Abb. 3). Die Bodenschweißnähte 38, 39 können durch zwei dicht hintereinander am Traghebel 11 angebrachte Schweißleisten 5 oder durch eine entsprechend breitere Schweißleiste 5 hergestellt werden. If short bags 18 are produced, they can be welded with the bottom 38, 39 and the opening edges 40, 41 are each generated next to one another and in the middle of the wider or close to each other with two welds each Welding points and in the middle of the lengths of film tubing in between be separated (Fig. 3). The bottom weld seams 38, 39 can by two close behind one another on the support lever 11 attached welding bars 5 or by a correspondingly wider one Welding bar 5 are produced.
Die Abtrennung der sonach paarweise entgegengesetzt liegenden einzelnen Folienbeutel 18 erfolgt dann einmal in der Mitte der breiteren Schweißnaht oder zwischen den dicht nebeneinanderliegenden Bodenschweißnähten 38, 39 und zum anderen in der Mitte der doppelten Beutellänge zwischen den Bodenschweißnähten. Die Quersehneideinrichtung 15 muß dann zwei Umdrehungen und Schnitte pro Schweißung ausführen. Den Hüpfrollen 19 wird dann an den Schnittstellen zwischen den Schweißstellen für die entstehenden, nebeneinanderliegenden Öffnungsränder 40, 41 der Beutel 18 erst eine Querbewegung nach einer Seite und gleich danach eine Querbewegung in entgegengesetzter Richtung erteilt, so daß zuerst die in Laufrichtung vorn liegenden Folienschlauchöffnungsränder 40 des vorhergehenden Beutels 18 und dann die unmittelbar dahinter liegenden Öffnungsränder 41 des folgenden Beutels 18 an der Schnittstelle durch seitliche Verschiebung der übereinanderliegenden Öffnungsränder zueinander geöffnet bzw. voneinander gelöst werden.The separation of the individual lying opposite in pairs Foil bag 18 then takes place once in the middle of the wider weld seam or between the closely adjacent bottom welds 38, 39 and on the other in the middle of double the bag length between the bottom welds. The cross cutting device 15 then has to make two turns and cuts per weld. The bouncy roll 19 is then used at the interfaces between the welding points for the adjacent opening edges 40, 41 of the bag 18 only a transverse movement to one side and immediately afterwards a transverse movement in the opposite direction issued so that first the film tube opening edges in the running direction 40 of the previous bag 18 and then the opening edges immediately behind it 41 of the following bag 18 at the interface by moving the superimposed opening edges opened to each other or detached from each other will.
Die auf und ab bewegbaren Hüpfrollen 19 sitzen auf einer Welle 42, welche mittels Ringnutscheibe 43, Rolle 44, Gestänge 45, Kurven- oder Exzenterscheibe 46 automatisch vom Maschinenantrieb in den eRorderlichen Augenblicken nach einer Seite verstellt und wieder zurückbewegt oder abwechselnd nach einer Seite und der entgegengesetzten Seite bewegt werden (Abb. 2). The jumping rollers 19, which can be moved up and down, sit on a shaft 42, which by means of annular groove disk 43, roller 44, linkage 45, cam or eccentric disk 46 automatically from the machine drive in the necessary moments after a Side adjusted and moved back again or alternately to one side and the opposite side (Fig. 2).
Die Bandleitungen 20, 21 und die Zugwalzen 22 23 transportieren die einzelnen Beutel 18 zur Ablage. The ribbon lines 20, 21 and the pulling rollers 22 23 transport the individual bag 18 for storage.
Die Zugwalzen 22 a und 23 a übernehmen den jeweils ankommenden Beutel 18 mit der Geschwindigkeit der Greiferkette der Kettengreiferablage 25 und transportieren ihn bis zu den Greifern 24 der Greiferkette, von denen der Beutel 18 ergriffen und zum Ablagetisch geführt und abgelegt wird. Durch die Kurvenscheibe 31 über Rolle 32, Hebel 33, Stange 34 wird die Zugwalze 23 a angehoben und gesenkt.The pull rollers 22 a and 23 a take over each incoming bag 18 at the speed of the gripper chain of the chain gripper tray 25 and transport him up to the grippers 24 of the gripper chain, from which the bag 18 is gripped and is guided to the storage table and deposited. By the cam 31 via role 32, lever 33, rod 34, the pull roller 23 a is raised and lowered.
Werden kurze Beutel in entgegengesetzter Lage ihrer Öffnungsränder auf der Folienschlauchbahn 1 hergestellt, so wird abwechselnd jeweils ein Beutel 18 von den Greifern 24 auf dem Ablegetisch 26 und der folgende Beutel in entgegengesetzter Richtung auf dem Ablegetisch 27 abgelegt. Um die Einstellung der Maschine zu erleichtern, ist die gesamte Kettenablage 25 als Einheit um den Drehpunkt30 des großen Greiferkettenzylinders nach oben schwenkbar angeordnet. Will be short bags in the opposite position of their opening edges produced on the tubular film web 1, a bag is alternated in each case 18 of the grippers 24 on the delivery table 26 and the following bag in the opposite direction Direction deposited on the delivery table 27. To make it easier to adjust the machine, is the entire chain storage 25 as a unit around the pivot point 30 of the large gripper chain cylinder arranged pivotable upwards.
