Taschenfederschlange 3. Der Abstand h zwischen den Trägern 17 ist derart bemessen, dass die Taschenfederschlangen 3, wenn sie in die Aufnahme 19 eingelegt sind, leicht zusammengedrückt werden und damit reibschlüssig von den Trägern 17 gehalten werden.Pocket spring snake 3. The distance h between the carriers 17 is dimensioned such that the pocket spring snakes 3, when they are inserted into the receptacle 19, are slightly compressed and thus frictionally held by the carriers 17.
Hinter der Trommel 13 ist eine Montagevorrichtung 25 für die Aufnahme der Taschenfederschlangen 3 angebracht . Auf der Montagevorrichtung 25 werden die Taschenfederschlangen 3 mit vertikal liegenden Achsen zusammengefügt und gehalten.Behind the drum 13, a mounting device 25 for receiving the pocket spring snakes 3 is attached. On the mounting device 25, the pocket spring snakes 3 are assembled and held with vertical axes.
Über der Trommel 13 ist weiter eine sich zwischen den beiden Seitenwänden 7 erstreckende Auftragsvorrichtung 21 zum Auftragen eines Klebers auf die Taschenfederschlangen 3 angeordnet. Auf der Auftragsvorrichtung 21 ist ein Auftragskopf 23 mit einer oder mehreren Auftragsdüsen parallel zur Achse 11 der Trommel 13 verfahrbar angebracht . Die Montagevorrichtung 25 lässt sich entlang von vertikal liegenden Führungen 27 mittels eines Handrades 29 oder einem entsprechenden Elektroantrieb vertikal verstellen und an die Höhe der Taschenfederschlangen 3 anpassen, welche verarbeitet werden.Above the drum 13 is further arranged between the two side walls 7 extending applicator 21 for applying an adhesive to the pocket spring 3 snakes. On the applicator 21, an applicator head 23 with one or more application nozzles is mounted movable parallel to the axis 11 of the drum 13. The mounting device 25 can be adjusted vertically along vertical guides 27 by means of a handwheel 29 or a corresponding electric drive and adapted to the height of the pocket spring coils 3, which are processed.
Innerhalb der Trommel 13 oder in diese eingreifend ist ein Einschieber 31 angeordnet, mit welchem diejenige Taschenfederschlange 3, welche sich auf der Höhe des Tisches 25 befindet, aus der Aufnahme 19 hinausgeschoben oder zur Montagevorrichtung hingezogen und an die letzte auf der Montagevorrichtung 25 stehende Taschenfederschlange 3 anpressen lässt.Within the drum 13 or in this engaging a slide 31 is arranged, with which the pocket spring snake 3, which is located at the level of the table 25, pushed out of the receptacle 19 or attracted to the mounting device and the last on the mounting device 25 standing pocket spring snake third can be pressed.
Nachfolgend wird die Funktionsweise der halbautomatischen Vorrichtung 1 zur Montage von Taschenfederschlangen 3 erläutert. Eine Bedienungsperson B entnimmt einem in den Figuren nicht dargestellten Magazin zusammengestellte Taschenfederschlangen 3 und legt diese an der Stelle a in die dort befindliche Aufnahme 19 ein. Dabei werden die Federn in der Schlange axial leicht zusammengedrückt, da die Aufnahme 19 bildenden Träger 17 einen kleineren Abstand aufweisen als die Höhe der Federn. Nun dreht die Bedienungsperson B von Hand die Trommel 13 bis sich die eingelegte Taschenfederschlange 3 in der Position b befindet. Diese Drehbewegung kann selbstverständlich auch durch ein Fusspedal oder einen Antriebsraotor erfolgen. Nun liegt vor der Bedienungsperson B an der Position a wieder eine leere Aufnahme 19, in die sie die nächste Taschenfederschlange 3 einlegt. Gleichzeitig wird die zuvor von Position a zur Position b geführte Taschenfederschlange 3 von der Auftragsvorrichtung 21 bzw. dem Auftragskopf 23, welcher sich axial über die Taschenfederschlange 3 bewegt, mit einem Kleber, z.B. einem Hotmelt oder dergleichen, beaufschlagt.Hereinafter, the operation of the semi-automatic device 1 for mounting pocket springs 3 will be explained. An operator B takes from a magazine, not shown in the figures compiled pocket spring snakes 3 and places them at the point a in the recording 19 located there. The springs in the queue are slightly compressed axially, since the receptacle 19 forming carrier 17 has a smaller distance than the height of the springs. Now the operator B turns by hand the drum 13 until the inserted pocket spring coil 3 is in position b. Of course, this rotation can also be done done by a foot pedal or a drive rotor. Now lies in front of the operator B at the position a again an empty receptacle 19, in which she inserts the next pocket spring snake 3. At the same time, the pocket spring coil 3 previously guided from position a to position b is acted upon by the application device 21 or the application head 23, which moves axially over the pocket spring coil 3, with an adhesive, for example a hot melt or the like.
Nach dem Einlegen der Taschenfederschlange 3 in die Aufnahme 19 und gleichzeitigem Beaufschlagen der vorangehenden Taschenfederschlange 3 mit einem Kleber erfolgt wiederum eine Drehbewegung der Trommel 13. Nach dieser Drehbewegung befindet sich die zuerst eingelegte Taschenfederschlange 3 in der Position c und die Achsen der Federn in der Taschenfederschlange 3 liegen nun vertikal, so dass sie vom Einschieber 31 aus der Aufnahme 19 hinaus auf die Montagevorrichtung 25 geschoben und dort an die hinterste Federschlange 3 angepresst und mit dieser verklebt werden können. Die Bedienungsperson B legt in diesem Zeitraum wiederum eine Taschenfederschlange 3 in die Aufnahme 19 an der Position a ein. Gleichzeitig wird die zuvor eingelegte Taschenfederschlange 3 von der Auftragsvorrichtung 21 mit einem Kleber beaufschlagt usw.After inserting the pocket spring snake 3 in the receptacle 19 and simultaneously applying the previous pocket spring snake 3 with an adhesive is again a rotational movement of the drum 13. After this rotational movement is the first inserted pocket spring snake 3 in the position c and the axes of the springs in the pocket spring snake 3 are now vertical, so that they pushed from the slide 31 from the receptacle 19 out on the mounting device 25 and there pressed against the rearmost spring coil 3 and can be glued to this. The operator B sets in this period, in turn, a pocket spring snake 3 in the receptacle 19 at the position a. At the same time the previously inserted pocket spring snake 3 is acted upon by the applicator 21 with an adhesive, etc.
Es finden also stets gleichzeitig drei Handlungen statt, nämlich Einlegen (a) einer Taschenfederschlange 3 in die Aufnahme 19, (b) Beaufschlagen der Taschenfederschlange 3 mit einem Kleber und (c) Überführen der mit einem Kleber beaufschlagten Taschenfederschlange 3 in die Montagevorrichtung 25 und gleichzeitiges Anpressen an die vorangegangene Taschenfederschlange 3.So there are always three actions taking place at the same time, namely inserting (a) a pocket spring snake 3 in the receptacle 19, (b) applying the pocket spring snake 3 with an adhesive and (c) transferring the acted upon with an adhesive pocket spring snake 3 in the mounting device 25 and simultaneous pressing against the preceding pocket spring snake. 3
In einer weiteren Ausbildung der Erfindung kann die Bedienungsperson B durch eine automatische Zuführung ersetzt werden. Zu diesem Zweck sind vor der Trommel 13 übereinander zwei Förderbänder 33 angeordnet, deren einander gegenüberliegende Trume 35 in einem gegenseitigen Abstand liegen, der etwas kleiner ist als die Höhe der zu verarbeitenden Taschenfederschlange 3. DieIn a further embodiment of the invention, the operator B can be replaced by an automatic feeder. For this purpose, two conveyor belts 33 are arranged one above the other in front of the drum 13, whose opposite strands 35 are at a mutual distance, which is slightly smaller than the height of the pocket spring snake to be processed 3. Die
Taschenfederschlangen 3 werden von einer aus dem Stand der Technik bekannten Winde- und Eintaschvorrichtung (nicht dargestellt und beschrieben) seitlich an die Förderbänder 33 herangeführt und können mittels eines Indexrades 39 zwischen die beiden Lasttrume 35 eingeführt werden. Die beiden Trume 35 können im Einführbereich vorzugsweise nicht völlig parallel laufend geführt sein, sondern deren Abstand ist im Bereich der Indexwalzen 39 etwas grösser, so dass die Taschenfederschlangen 3 während des Einzugs zwischen die beiden Förderbänder 33 sukzessive axial leicht zusammengepresst werden (Konizität der Förderbänder 33 nicht dargestellt) . Sobald eine Taschenfederschlange 3 direkt vor der Trommel 13 liegt, wird der Antrieb der Förderbänder 3 unterbrochen und die Taschenfederschlange 3 mit einem balkenförmigen Vorschubmittel 37 in die Aufnahme 19 an der Trommel 13 eingeschoben. Das Einschieben bzw. Einlegen der Taschenfederschlangen 3 in die Aufnahmen 19 der Trommel 13 erfolgen in diesem Falle nicht unmittelbar seitlich des Scheitels S der Trommel 13 (Position a) , sondern in dem Moment, in welchem die Aufnahme 19 an der Vorderseite der Trommel 13 liegt (Position d) .Pocket spring snakes 3 are brought by a known from the prior art winch and Eintaschvorrichtung (not shown and described) laterally to the conveyor belts 33 and can be introduced by means of an index wheel 39 between the two Lasttrume 35. The two strands 35 can preferably not be guided completely parallel in the lead-in area, but their spacing is slightly greater in the area of the index rollers 39, so that the pocket spring snakes 3 are compressed slightly successively axially during the intake between the two conveyor belts 33 (conicity of the conveyor belts 33 not shown) . Once a pocket spring snake 3 is located directly in front of the drum 13, the drive is the Conveyor belts 3 interrupted and the pocket spring snake 3 is inserted with a bar-shaped feed means 37 in the receptacle 19 on the drum 13. The insertion or insertion of the pocket spring snakes 3 in the receptacles 19 of the drum 13 in this case not directly to the side of the apex S of the drum 13 (position a), but in the moment in which the receptacle 19 is located on the front side of the drum 13 (Position d).
Das Beaufschlagen mit einem Kleber kann wie in der manuell beschickten Vorrichtung 1 gemäss den Figuren 1 und 2 hinter dem Scheitel S der Trommel 13 erfolgen oder, wie in Figur 3 dargestellt, wenn die Aufnahme 19 im Scheitel liegt und die Achsen der Federn in den Taschen dort horizontal ausgerichtet sind. Sowohl das Beaufschlagen mit einem Kleber als auch das nachfolgende Herausschieben der Taschenfederschlangen 3 aus den Aufnahmen 19 der Trommel 13 erfolgen wie bei der manuell beschichteten Vorrichtung.The application of an adhesive can be carried out as in the manually fed device 1 according to Figures 1 and 2 behind the apex S of the drum 13 or, as shown in Figure 3, when the receptacle 19 is in the vertex and the axes of the springs in the pockets aligned horizontally there. Both the application of an adhesive and the subsequent pushing out of the pocket spring coils 3 from the receptacles 19 of the drum 13 take place as in the case of the manually coated device.
An einer an der Achse 11 befestigen Leiste sind in axialen Abständen im Beschickungsbereich (d bis a) Stege 41 angeordnet . Die Abstände entsprechen den Abständen der Achsen der Federn in den Federschlangen 3. Um Federschlangen 3 mit Federn, deren Durchmesser grösser oder kleiner sind, verarbeiten zu können, lassen sich die Stege 41 in axialer Richtung auf der Trommel verschieben. Das Verschieben und wieder neu Positionieren der Stege 41 kann von Hand oder mit einem geeigneten (nicht dargestellten) Antrieb erfolgen.At a fixed to the axis bar 11 webs 41 are arranged at axial intervals in the feed area (d to a). The distances correspond to the distances of the axes of the springs in the spring coils 3. In order to be able to process spring coils 3 with springs whose diameters are larger or smaller, the webs 41 can be displaced in the axial direction on the drum. The shifting and repositioning of the webs 41 can be done by hand or with a suitable (not shown) drive.
Die Stege 41 können, falls erwünscht, axial um einen halben Stegabstand verschoben werden. Dies ermöglicht es, die Federn in den Taschenfederschlangen 3 entweder in sogenannter Parallelmontage anzuordnen (vgl. Figur 4, obere Hälfte der Figur) oder in einer sogenannten versetzten Montage (vgl. Figur 4, untere Hälfte der Figur) . Bei in Parallelmontage angeordneten Taschenfederschlangen 3 liegen die darin befindlichen Federn jeweils in horizontaler und in vertikaler Richtung gesehen stets auf einer Linie. Bei versetzter Montage bilden die Federn in horizontaler Richtung gesehen eine Zick-Zack-Linie . Das Verschieben der Leisten mit den darauf montierten Stegen 41 kann auf Tastendruck durch einen Antrieb erfolgen oder manuell durch die Bedienungsperson B. The webs 41 can, if desired, be moved axially by half a distance between webs. This makes it possible to arrange the springs in the pocket spring coils 3 either in so-called parallel assembly (compare Figure 4, upper half of the figure) or in a so-called offset assembly (see Figure 4, lower half of the figure). When arranged in parallel mounting pocket spring coils 3, the springs located therein are always in a horizontal and vertical direction always on a line. When offset mounting the springs form a zig-zag line in the horizontal direction. The displacement of the strips with the webs 41 mounted thereon can be carried out by a drive at the push of a button or manually by the operator B.
