Abstract
Description
Maschine zur Herstellung von kissenförmigen, saugfähigen Machine for the production of pillow-shaped, absorbent
Einlagen Die Erfindung betrifft eine Maschine zur Herstellung von kissenförmigen Einlagen für Damenbinden, Windeln, Verbandsstoffe u.dgl., bestehend aus einer Trommel mit mehreren im Trommelmantel angeordneten, gegen die Umfangsfläche offenen Mulden, welche über Kanäle mit einer Vakuumquelle verbunden sind, und einer dem Trommelmantel gegenüberliegend angeordneten Einrichtung zum Zuführen von Fasern, Faserflocken u.dgl. zur Bildung der Kissen. Deposits The invention relates to a machine for the production of pillow-shaped inserts for sanitary napkins, diapers, bandages and the like., consisting from a drum with several arranged in the drum shell, against the circumferential surface open wells, which are connected to a vacuum source via channels, and one device for feeding fibers arranged opposite the drum shell, Fiber flakes and the like to form the pillows.
Bei den bekannten Maschinen der in Betracht kommenden Art sind die Mulden im Trommelmantel der Form der Kissen entsprechend ausgebildet, d.h., daß die Mulden flachere und tiefere Bereiche aufweisen, damit die Kissen im Querschnitt ein bestimmtes gewünschtes Profil erhalten.In the known machines of the type under consideration are the Depressions in the drum shell corresponding to the shape of the cushion, i.e. that the troughs have shallower and deeper areas, so that the cushions in cross-section get a specific desired profile.
Es hat sich im Betrieb der bekannten Maschinen gezeigt, daß häufig, diejenigen Bereiche, in welchen die Kissen eine größere Stärke aufweisen sollen als in den anderen Bereichen, nicht voll mit Faser- und bzw. oder Faserflockenmaterial ausgefüllt sind. Dies ist eine im höchsten Maße unerwünschte Erscheinung, weil die in Betracht kommenden Kissen dadurch ungleichmäßig in Bezug auf ihre Form wie auch auf ihre Saugfähigkeit sind, so daß die Qualität derartiger Kissen zu wünschen übrig läßt.It has been shown in the operation of the known machines that often those areas in which the cushions should have a greater thickness than in the other areas, not full of fiber and / or fiber flake material are filled out. This is a highly undesirable phenomenon because of the Eligible pillows make them uneven in terms of their shape as well on their absorbency, so that the quality of such pillows is poor leaves.
Der Erfindung liegt die Aufgabe zugrunde, den vorerwähnten Nachteil zu vermeiden und die in Betracht kommende Maschine in der Weise auszubilden, daß die von ihr abgegebenen Kissen sämtlichst die gleiche Beschaffenheit, Form und Wirksamkeit haben.The invention is based on the aforementioned disadvantage to avoid and to train the machine in question in such a way that the cushions she delivers are all of the same quality, shape and effectiveness to have.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlaren die Maschine zur Herstellung von kissenförmigen, saugfähigen Elrlagen für Damenbinden, Windeln, Verbandsstoffe u.dgl. in der Weise auszubilden, daß die Mulden im Trommelmantel bzw. in dessen Trommelmantelsegmenten in mehrere Zonen unterteilt und alle im Bereich einer Zone in die Mulde einmündenden Kanäle über eine gemeinsame, mit einer ein Regel- und Steuerventil enthaltenden Vakuumleitung verbunden sind.To solve this problem, according to the invention, the Machine for the production of pillow-shaped, absorbent pads for sanitary napkins, Diapers, bandages and the like in the Way to train that Wells in the drum shell or in its drum shell segments divided into several zones and all channels opening into the trough in the area of a zone via a common, are connected to a vacuum line containing a regulating and control valve.
Weitere Merkmale gehen aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung eines in den Figuren 1 und 2 schematisch dargestellten, besonders bevorzugten Ausführungsbeispiels hervor. Es zeigen: Fig. 1 einen Schnitt durch ein Trommelmantelsegment des Trommelmantels, und Fig. 2 eine Aufsicht auf das Trommelmantelsegment gemäß Fig. 1.Further features emerge from the subclaims and from the following Description of a particularly preferred shown schematically in FIGS Embodiment. 1 shows a section through a drum shell segment of the drum shell, and FIG. 2 shows a plan view of the drum shell segment according to FIG Fig. 1.
Üblicherweise ist der Trommelmantel 11 aus mehreren gleichen Trommelmantelsegmenten 12 zusammengesetzt. Jedes einzelne Segment 12 besitzt wenigstens eine Mulde 13, die in demjenigen Bereich 14, in welchem das Kissen eine größere Stärke aufweisen soll, tiefer ist als in den übrigen Bereichen 15.The drum shell 11 is usually made up of several identical drum shell segments 12 composed. Each individual segment 12 has at least one trough 13, those in the area 14 in which the cushion has a greater thickness is lower than in the other areas 15.
Wie aus Fig. 2 ersichtlich, befindet sich der vertiefte Bereich 14 der Mulde 13 in der Mitte. Im Grund 16 der Mulde 13 befinden sich im Trommelmantelsegment 12 querverlaufende Kanäle 17, in die durch das Segment 12 hindurchgehende Bohrungen 18 einmünden.As can be seen from FIG. 2, the recessed area 14 is located the trough 13 in the middle. In the base 16 of the trough 13 are located in the drum shell segment 12 transverse channels 17 into which bores extending through segment 12 18 merge.
Wie ersichtlich, weist die Mulde 13 einen tieferen, mittleren Bereich 14 und einen äußeren, flacheren Bereich 15 auf. Die Kanäle 17a im tieferen Bereich 14 haben keine Verbindung mit den Kanälen 17b im flacheren Bereich 15 der Mulde 13. Die in die Kanäle 17a bzw. 17b einmündenden Bohrungen 18a bzw. 18b liegen in unterschiedlichen Radialebenen des Trommelmantels 11.As can be seen, the trough 13 has a deeper, central area 14 and an outer, flatter area 15. The channels 17a in the deeper area 14 have no connection with the channels 17b in the shallower area 15 of the trough 13. The bores 18a and 18b opening into the channels 17a and 17b are located in different radial planes of the drum shell 11.
An der Innenseite des Trommelmantels 11 liegen Anschlußstücke 19 am Ende der Vakuumleitung 20 an, über welche hinweg der Trommelmantel 11 geführt wird. Einer jeden Radialebene, in welcher Bohrungen 18 im Trommelmantelsegment 12 angeordnet sind, ist ein Anschlußstück 19 zugeordnet. Mittels des in der Vakuumleitung 20 befindlichen Steuer- und Regelventils lassen sich die Intensität des Vakuums in der Kammer 21 des Anschlußstücks 19 sowie dessen Zeitdauer regeln bzw. steuern.On the inside of the drum shell 11 are connecting pieces 19 on End of the vacuum line 20, over which the drum shell 11 is guided. Each radial plane in which bores 18 are arranged in the drum shell segment 12 are, a connector 19 is assigned. By means of the located in the vacuum line 20 Control and regulating valve can control the intensity of the vacuum in the chamber 21 of the connector 19 and its duration regulate or control.
Auf der Außenseite des Trommelmantels 11 befindet sich im Bereich der Anschlußstücke 19 die nicht dargestellte Einrichtung zur Zuführung der Fasern und Faserflocken u.dgl., welche infolge des in der Mulde 13 herrschenden Vakuums in die Mulde 13 eingesaugt werden. Die Insentität des Vakuums beeinflußt die Dichte des aus Fasern und Flocken u.dgl. gebildeten Kissens und die Zeitdauer gewährleistet, daß die Mulde vor allem im tieferen Bereich 14 vollständig mit Fasern bzw.On the outside of the drum shell 11 is in the area of the connecting pieces 19, the device, not shown, for supplying the fibers And fiber flocks and the like. Which as a result of the vacuum prevailing in the trough 13 be sucked into the trough 13. The existence of the vacuum affects the density of the cushion formed from fibers and flakes and the like and ensures the duration, that the trough, especially in the deeper area 14, is completely covered with fibers or
Flocken u.dgl. ausgefüllt wird. Im vorliegenden Fall ist das Vakuum im mittleren, tieferen Bereich längere Zeit wirksam als in dem den mittleren Bereich 14 umgebenden flacheren, äußeren Bereich 15.Flakes and the like is filled. In the present case, that is vacuum effective for a longer time in the middle, lower area than in the middle area 14 surrounding flatter, outer area 15.
Die Mulden können jede beliebige Form haben und entsprechen der Form des mit ihrer Hilfe zu bildenden Kissens, und zwar sowohl in Bezug auf die äußere Kontur als auch den Querschnitt in Längs- und Querrichtung. Damit die relativ feinen Fasern und Flocken u.dgl. nicht in die im Grund 16 der Mulde befindlichen Kanäle 17 eindringen und diese bzw. die Bohrungen 18 verstopfen, ist der Grund 16 mit einem feinmaschigen Sieb 22 bedeckt.The troughs can have any shape and correspond to the shape of the cushion to be formed with their help, both in relation to the external Contour as well as the cross-section in the longitudinal and transverse direction. So that the relatively fine Fibers and flakes and the like not in the channels located in the base 16 of the trough 17 penetrate and block this or the bores 18, the bottom 16 is with a fine-mesh sieve 22 covered.
Wie Versuche gezeigt haben, ist es möglich, mit der erfindungsgemäß ausgebildeten Maschine Kissen für jeden Zweck und in jeder Form in der erwünschten Gleichmäßigkeit und Qualität zu erhalten.As tests have shown, it is possible with the invention trained machine pillows for any purpose and in any shape in the desired Maintain consistency and quality.
