Abstract
Description
Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt F i g. 1 eine Seitenansicht der Ablage- und Stapeleinrichtung in schematischer Darstellung, F i g. 2 eine Draufsicht auf die Vorrichtung nach Fig. 1, F i g. 3 einen von zwei Armen bekannter Bauart gehaltenen Doppelbeutel im Zeitpunkt seines Aufnadelns, Fig.4 bis 6 verschiedene Ausführungsformen von Armen erfindungsgemäßer Ausbildung in perspektivischer Ansicht und im Querschnitt, F i g. 7 einen von zwei gemäß der F i g. 4 ausgebildeten Armen gehaltenen Doppelbeutel im Zeitpunkt des Aufnadelns. An embodiment of the invention is described below with reference to FIG Drawing explained in more detail. In this FIG. 1 is a side view of the storage and stacking device in a schematic representation, FIG. 2 is a plan view of FIG the device according to FIG. 1, F i g. 3 one of two poor known Design held double bag at the time of its needling, Fig. 4 to 6 different Embodiments of arms according to the invention training in a perspective view and in cross section, F i g. 7 one of two according to FIG. 4 trained arms held double bag at the time of needling.
Auf der im Maschinengestell gelagerten Welle 1 sind Naben befestigt, die radiale Arme in gleichen Winkelabständen tragen, so daß sich zwei mit Abstand voneinander angeordnete Speichenräder 2 ergeben. Die einzelnen Speichen dieser Speichenräder 2 weisen Ansaugöffnungen auf, die mit einer Vakuumpumpe verbunden sind. Das Vakuum ist dabei so gesteuert, daß die beiden zusammenwirkenden Speichen 3 in dem Moment mit Vakuum beaufschlagt werden, wenn sie sich unterhalb des Übergaberechens 4 befinden. Hubs are attached to the shaft 1, which is mounted in the machine frame, carry the radial arms equally angularly spaced so that two are spaced Spoked wheels 2 arranged from one another result. The individual spokes of these spoked wheels 2 have suction openings that are connected to a vacuum pump. The vacuum is controlled so that the two interacting spokes 3 at the moment be applied with a vacuum when they are below the transfer rake 4.
Dadurch wird das auf dem Übergaberechen 4 befindliche Werkstück angesaugt und so lange festgehalten, bis das Werkstück während der Weiterdrehung der Speichenräder 2 im Uhrzeigersinn auf eine mit nach oben ragenden Zinken 5 besetzte Transportkette 6 aufgenadelt ist.As a result, the workpiece located on the transfer rake 4 is sucked in and held there until the workpiece continues to rotate with the spoked wheels 2 clockwise onto a conveyor chain with upwardly projecting prongs 5 6 is needled.
F i g. 2 zeigt, daß es sich bei der Transportkette 6 um zwei nebeneinander angeordnete Transportketten handelt, die sich mittig zwischen den beiden Speichenrädern 2 befinden. Die Transportketten sind im Abstand voneinander mit Nadeln 5', 5" versehen, die auf den Obertrumen der Transportketten senkrecht stehen. F i g. 2 shows that there are two side by side in the transport chain 6 arranged transport chains are, which are centered between the two spoked wheels 2 are located. The transport chains are provided with needles 5 ', 5 "at a distance from each other, which are vertical on the upper strands of the transport chains.
Diese Nadeln 5', 5" bilden zu der Welle 1 parallele Nadelreihen, auf die zum Zwecke der Stapelung die Beutel längs ihrer perforierten Streifen aufgenadelt werden. Wenn ein Stapel mit einer genügenden Anzahl von Doppelbeuteln gebildet worden ist, erfolgen beispielsweise vier Leertakte, während derer der fertige Stapel abtransportiert wird.These needles 5 ', 5 "form rows of needles parallel to the shaft 1 which for the purpose of stacking, the bags are needled along their perforated strips will. When a pile has been made with a sufficient number of twin bags there are, for example, four idle cycles during which the finished stack is transported away will.
Anschließend wird der Doppelbeutelblock durch einen mittleren Trennschnitt mit einem heißen Messer in zwei Einzelblöcke getrennt. Unterdessen sind durch den intermittierenden Antrieb der Transportkette neue Nadeln in die Aufnahmestellung gefahren worden, so daß die Bildung des folgenden Stapels erfolgen kann. Then the double bag block is cut through a middle separating cut separated into two individual blocks with a hot knife. Meanwhile, by that intermittent drive of the transport chain new needles in the receiving position has been driven so that the formation of the following stack can take place.
Die einzelnen Werkstücke selbst werden von einer Flachbahn 9, die beidseitig so umgeschlagen ist, daß sich die beiden Umschlagteile 7 und 8 nicht berühren, durch eine Schweißeinrichtung 10 abgetrennt, wobei der Vorzug der Bahn 10 durch die Vorzugsrollen 11 erreicht wird, welche mit mehreren Ringnuten 12 versehen sind. The individual workpieces themselves are of a flat track 9, the is turned over on both sides so that the two cover parts 7 and 8 are not touch, separated by a welding device 10, the preference of the web 10 is achieved by the preferred rollers 11, which are provided with several annular grooves 12 are.
Durch die Ringnuten der oberen und der unteren Vorzugswalze ist jeweils ein Blasluftrechen 13 und 14 geführt, die an im Maschinenrahmen 15 drehbar gelagerten Schwenkarmen 16 und 17 befestigt sind. Der von den Luftrechen 13 und 14 in Förderrichtung ausgeblasene Luftstrom dient zum Austragen des von den Vorzugsrollen 11 abgezogenen Bahnteils bei geöffneter Schweißeinrichtung 10 bis auf den Ablagerechen 4.Through the annular grooves of the upper and the lower feed roll is in each case a blown air rake 13 and 14 out, the rotatably mounted on in the machine frame 15 Swivel arms 16 and 17 are attached. That of the air rake 13 and 14 in the conveying direction The blown air stream serves to discharge the air drawn off from the feed rollers 11 Part of the track with the welding device 10 open except for the storage rake 4.
Bei den Doppelbeuteln, wie sie in der F i g. 2 dargestellt sind, befinden sich in den von den Umschlägen 7 und 8 nicht überdeckten Bereich 4 Ausstanzungen, wobei die Ausstanzungen 18 zum Beutel 19 und die Ausstanzungen 20 zum Beutel 21 gehören. Die Ausstanzungen 18 müssen dabei auf die Nadeln 5' und die Ausstanzungen 20 auf die Nadeln 5" aufgenadelt werden. Wie die F i g. 3 zeigt, ist es in der Praxis häufig vorgekommen, daß sich die von den Saugöffnungen 22 und 24 gehaltenen, noch zusammenhängenden Beutel 19 und 21 während der Drehbewegung der Arme 3 derart entgegen der Drehrichtung durchwölbten, daß sich die Stanzungen 18 und 20 nicht genau über den Nadeln 5' bzw. 5" befanden, so daß die Beutel nicht ordnungsgemäß aufgenadelt werden konnten. Dieses Problem ist erfindungsgemäß dadurch gelöst worden, daß die Saugöffnungen in den Armen 3 entsprechend der F i g. 4 bis 6 ausgebildet werden. In the case of the double bags as shown in FIG. 2 are shown, there are 4 cut-outs in the area not covered by the envelopes 7 and 8, the cutouts 18 for the bag 19 and the cutouts 20 for the bag 21 belong. The cutouts 18 must be on the needles 5 'and the cutouts 20 can be needled onto the needles 5 ". As FIG. 3 shows, it is in practice it often happened that the held by the suction ports 22 and 24, still coherent bags 19 and 21 during the rotational movement of the arms 3 in this way arched through the direction of rotation that the punchings 18 and 20 are not exactly over the needles 5 'and 5 "respectively, so that the bags were not properly needled could become. This problem has been solved according to the invention in that the Suction openings in the arms 3 according to FIG. 4 to 6 can be formed.
Durch eine derartige Ausbildung wird, wie die F i g. 7 zeigt, erreicht, daß sich der Doppelbeutel in9, 21 zum Teil um die Arme 3 herumlegt und dabei straff gehalten wird.Such a design, as shown in FIG. 7 shows achieved that the double bag in 9, 21 lies partly around the arms 3 and is taut in the process is held.
Auf diese Weise ist erreicht, daß die Ausstanzungen 18 und 20 eine exakt ausgerichtete Lage zu den Nadeln 5' und 5" einnehmen, so daß eine ordnungsgemäße Aufnadelung gewährleistet ist.In this way it is achieved that the punchings 18 and 20 one take exactly aligned position to the needles 5 'and 5 ", so that a proper Needling is guaranteed.
