Abstract

The Parent Patent No. 2924106 described a method of producing bags of thermoplastic foil by stacking the bags on needles to a pile and welding them by heated pins in line with the needles. The consumption of material can be reduced and less waste produced by joining two bags, produced by splitting the top centre of a flat hose, by the bottom foil. The needle holes and the welding holes are arranged along the centre line of this strip of bottom foil. Two parallel perforation lines flank the line of holes.

In dem Hauptpatent ... (Patentanmeldung P 29 24 106.3) ist zur Herstellung von verblockten Beuteln von der Aufgabe ausgegangen worden, diese aus dünnwandiger, thermoplastischer Kunststoffolie bei geringem Abfall zu verblocken. Weiterhin ist als Vorrichtung in der Verblockungseinrichtung eine Leiste angegeben, die an einer Seite und in einer Linie oder im wesentlichen in einer Linie angeordnet die Nadeln zum Verblocken und die Schweißdorne zum Verblocken trägt.In the main patent ... (patent application P 29 24 106.3) is for production of blocked bags, the task has been assumed to consist of thin-walled, to block thermoplastic plastic film with little waste. Furthermore is a bar as a device in the locking device specified, which are arranged on one side and in a line or substantially in a line the needles for blocking and the welding mandrels for blocking.

Die vorliegende Erfindung geht von der Aufgabe aus, mit den Mitteln des Hauptpatentes weitere Formen verblockter Beutel zu schaffen, die einen geringen Materialaufwand und somit Abfall für den verblockten Streifen haben.The present invention is based on the object with the means of the main patent to create other forms of blocked bags that have a low Material costs and thus waste for the blocked strip.

Zur Lösung dieser Aufgabe wird bei Beuteln aus thermoplastischer Kunststoffolie, die auf Nadeln zu einem Block gestapelt und durch erhitzte Dorne, die in der Linie der Nadeln angeordnet sind, miteinander verschweißt sind, erfindungsgemäß vorgeschlagen, daß einstückig zwei mit ihren Beutelöffnungen einander zugekehrten Beutel jeweils über eine zugeordnete Perforation mit einem Streifen verbunden sind, der mit den Nadellöchern und mit den Verblockungslöchern versehen ist.To solve this problem, bags made of thermoplastic plastic film, which are stacked on needles into a block and through heated mandrels that are in line the needles are arranged, welded together, proposed according to the invention, that in one piece two bags facing each other with their bag openings are connected via an associated perforation to a strip which is connected to the Pinholes and is provided with the locking holes.

Bei dieser Lösung kann der genannte Verblockungsstreifen zweilagig sein in gleicher Weise wie die beiden Lagen, die die Beutel bilden.In this solution, said blocking strip can have two layers be in the same way as the two layers that make up the bags.

Besonders vorteilhaft besteht der Verblockungsstreifen jedoch lediglich aus einer Folienlage.However, the blocking strip only exists particularly advantageously from a film layer.

Die Beutelöffnungen können dicht an diesen Verblockungsstreifen heranreichen. Es ist jedoch auch möglich, die Beutel mit einer überklappe zu versehen und in der Uberklappe Aufhängelöcher anzuordnen.The bag openings can reach close to these blocking strips. However, it is also possible to use the bags to be provided with a flap and to arrange hanging holes in the flap.

Eine Vorrichtung zum Herstellen des Blockes aus Beuteln ist gekennzeichnet durch das Merkmal, daß zu beiden Seiten der die Nadeln und die erhitzten Dorne tragenden Leiste jeweils ein Perforationsmesser angeordnet ist.Apparatus for making the block of bags is identified by the feature that on both sides of the bearing the needles and the heated mandrels Bar a perforation knife is arranged in each case.

Die Erfindung ist in der Zeichnung beispielhaft erläutert.The invention is illustrated by way of example in the drawing.

Es zeigen: Fig. 1 das Verfahren zum Herstellen der Beutel und deren Verblockung in der Ansicht von oben und im wesentlichen schematisch, Fig. 2 in perspektivischer Darstellung einen Teilausschnitt der Beutel entsprechend dem Schnitt II-II nach Fig.3, Fig. 3 die durch den Verblockungsstreifen miteinander verbundenen Beutel, Fig. 4 das Aufhängen der verblockten Beutel, Fig. 5 die Verblockungsvorrichtung in perspektivischer und im wesentlichen schematischer Darstellung.The figures show: FIG. 1 the method for producing the bags and their Blocking in the view from above and essentially schematically, FIG. 2 in perspective Representation of a partial section of the bag according to section II-II Fig. 3, Fig. 3 the bags connected to one another by the interlocking strip, 4 shows the hanging of the blocked bags, FIG. 5 shows the blocking device in perspective and essentially schematic representation.

Nach Fig. 1 wird ausgehend von einem Schlauch aus thermoplastischer Kunststoffolie 10 lediglich die obere Wandung 11 und nicht die untere Wandung 12 durch ein Messer 13 fortlaufend und in Längsrichtung aufgeschnitten. Dann wird der so entstandene Halbschlauch so weit aufgeweitet, daß die Schnittkanten 14 und 15 einen Abstand zueinander haben. Dadurch liegt der mittlere Teil der unteren Folie 12 frei. Anschliessend werden Seitennahtschweißungen 16 und 17 mit dem dazwischen liegenden Trennschnitt 18 angebracht und somit zusammenhängende Beutel 19 und 20 geschaffen. Diese Beutel werden dann in einer Verblockungseinrichtung miteinander verbunden. Die Verbindung erfolgt durch die Wandung 12 in einem durch einen mittleren Streifen gebildeten Feld 21, das seitlich begrenzt wird durch die beiden Perforationslinien 22 und 23. In diesem Streifen 21 sind die durch erhitzte Dorne geschaffenen Verblockungslöcher 24 und die Nadellöcher 25 vorhanden, die in einer Linie oder im wesentlichen einer Linie angeordnet sind. Über die jeweiligen Perforationen 22 und 23 werden die Beutel 19 und 20 von dem Streifen 21 getrennt.According to Fig. 1, starting from a hose made of thermoplastic Plastic film 10 only the upper wall 11 and not the lower wall 12 cut open continuously by a knife 13 in the longitudinal direction. Then the the resulting half tube widened so far that the cut edges 14 and 15 have a distance from each other. As a result, the middle part of the lower film is located 12 free. Then side seam welds 16 and 17 are made with the in between lying separating cut 18 attached and thus coherent bags 19 and 20 created. These bags are then interlocked with one another tied together. The connection is made through the wall 12 in a central one Strip formed field 21, which is laterally limited by the two perforation lines 22 and 23. In this strip 21 are the locking holes created by heated mandrels 24 and the pinholes 25 present, which are in a line or substantially one Line are arranged. About the respective perforations 22 and 23, the bags 19 and 20 separated from the strip 21.

Fig. 1 zeigt Beutel 59 und 20, die im wesentlichen keine Überklappe haben, weil die jeweilige Beutelöffnung, beim Beutel 19 die Schnittkante 14, dicht an die Perforationslinie 23 heranreicht, die nach dem Abtrennen die Kante der Beutelöffnung darstellt.Fig. 1 shows bags 59 and 20 which have essentially no over flap have because the respective bag opening, the cut edge 14 of the bag 19, tight reaches up to the perforation line 23 which, after being severed, is the edge of the bag opening represents.

Fig. 3 zeigt die Lösung, daß der Beutel 19 mit einer Überklappe 26 und der Beutel 20 mit einer Überklappe 27 versehen ist. In diesem sind jeweils zugeordnet Aufhängelöcher 28 vorhanden.Fig. 3 shows the solution that the bag 19 with a flap 26th and the bag 20 is provided with an over flap 27. In this are each assigned Suspension holes 28 available.

Fig. 4 zeigt, daß an einem Stander 29, der nach oben gerichtete Stifte 30 hat, die verblockten Beutel nach Fig. 1 bzw.Fig. 4 shows that on a stand 29, the upwardly directed pins 30, the blocked bags according to FIG. 1 and

Fig. 3 über die Verblockungslöcher 24 aufgehangen sind. Sie hängen auf beiden Seiten herab und werden über die Perforationen 22 und 23 von dem jeweiligen Verblockungsstreifen 21 abgetrennt.3 are suspended via the locking holes 24. they hang on both sides and are accessed via the perforations 22 and 23 of the respective Blocking strips 21 separated.

Fig. 5 zeigt die Verblockungsvorrichtung. An der Oberseite 31 der Leiste 32 sind Nadeln 33 und erhitzte Dorne 34 in einer Linie und abwechselnd angebracht in der Weise, daß nach mehreren Nadeln jeweils ein erhitzter Dorn folgt. Mit dieser Leiste 32 wirkt zusammen die Gegenleiste 33, die den Nadeln und den erhitzten Dornen 34 jeweils zugeordnete Bohrungen hat.Fig. 5 shows the locking device. At the top 31 of the Bar 32 are needles 33 and heated mandrels 34 in a line and alternately attached in such a way that after several needles a heated mandrel follows. With this Bar 32 cooperates with the counter bar 33, the needles and the heated thorns 34 each has assigned holes.

Zu beiden Seiten der Leiste 32 sind jeweils eine Gegenauflage 36 und 37 für jeweils zugeordnete Stanzmesser 38 und 39 angeordnet, die eine sägezahnartige Schneide haben, um die Perforationsschnitte 22 und 23 zu bilden.On both sides of the bar 32 are each a counter support 36 and 37 arranged for each associated punching knife 38 and 39, which have a sawtooth-like Have cutting edges to form the perforation cuts 22 and 23.
