Aus der DE 40 42 304 AI ist ein Taschenfederkern der eingangs bezeichneten Art bekannt. Bei solchen Taschenfederkernen , können die entsprechenden Langlocher mit Abstand von den Stirnflachenebenen der Federn enden. Vorzugsweise sind die Langlocher mittig zwischen den Ebenen ausgebildet, wobei dieFrom DE 40 42 304 AI a pocket spring core of the type mentioned is known. With such pocket spring cores, the corresponding elongated holes can end at a distance from the end face planes of the springs. The elongated holes are preferably formed centrally between the levels, the
Langlocher in Stegbereichen der tuchartigen Umhüllung angeordnet sind, die zwischen den emgetaschten Federn der Ketten liegen. Dabei weisen nur die Ketten erster Art entsprechende Langlocher auf, wahrend die Ketten zweiter Art ohne solche Lochausbildungen gefertigt sind . In dem eingangs bezeichneten Stand der Technik sind die Vorteile eines solchen Taschenfederkernes schon beschrieben. Durch die entsprechende Ausbildung ist es möglich durch eine Anzahl parallel zueinander angeordneter Ketten erster Art, bei denen die Langlöcher jeweils koaxial zueinander ausgerichtet sind, durch diese koaxial zueinander ausgerichteten Langlöcher eine Kette zweiter Art hindurchzustecken und so anzuordnen, daß die Ketten zweiter Art mit ihrem Verbindungssteg jeweils in einem Langloch sitzen, Hiermit ist ein fester mechanischer Verbund der Ketten miteinander erreicht, so daß ein entsprechender Taschenfederkern gebildet ist. Es ist auch schon beschrieben, daß zum Erleichtern des Durchschiebens der Ketten durch die Langlöcher die Ketten zusammengedrückt werden können, so daß sie dann vereinfacht durch die schlitzartigen offenen Langlöcher geschoben werden können. Nach dem Auffedern der Federn ist eine mechanische Verrastung erreicht. Die Federn sind vorzugsweise als Tonnenfedern ausgebildet. Der auf diese Weise gefertigte Taschenfederkern stellt hinsichtlich seines Zusammenhaltes ein ausgezeichnetes Zwischenprodukt dar, welches mit geringer Sorgfalt gehandhabt werden kann, bis es zu einer Matratze in endgültiger Form verarbeitet ist. Ausgehend von dem eingangs bezeichneten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zur Herstellung eines solchen Taschenfederkernes zu schaffen. Zur Losung dieser Aufgabe schlagt die Erfindung vor, daß die Vorrichtung im wesentlichen aus drei Modulen besteht, die in Reihe nebeneinander angeordnet sind, daß das erste, mittlere Modul eine rechenartige Zufuh vorrichtung umfaßt, mittels derer die Anzahl von Kett erster Art nebeneinander, parallel zueinander und mit zueinander fluchtenden Langlochern ausrichtbar und einem Schußpfad zufuhrbar sind, so daß jeweils ein durch die Langlocher der benachbarten Ketten aufgespannter, kanalartiger Einschubpfad für eine Kette der zweiten Art gebildet ist, daß am einen Ende des Einschubpfades neben dem ersten, mittleren Modul ein zweites Modul angeordnet ist, mittels dessen die Kette zweiter Art lagerichtig zum Einschubpfad ausrichtbar und in Richtung parallel zur Mittelachse der Federn der Kette zweiter Art auf eine geringe Hohe zusammenpreßbar ist, die gleich oder geringer als die Hohe der zueinander fluchtenden, den Einschubpfad bildenden Langlocher der Ketten erster daß am anderen Ende des Einschubpfades neben dem erst Modul ein drittes Modul angeordnet ist, das ein Transportmittel aufweist, welches koaxial zum Einschu pfad durch diesen hindurch verfahrbar ist, mittels dessen das freie Ende der im zweiten Modul befindlich Kette zweiter Art erfaßbar und durch den Einschubpfad in eine Position bewegbar ist, in der die einander kreuzende Soliposition der Kette zweiter Art relativ zur Schar der Ketten erster Art erreicht ist.Elongated holes are arranged in the web areas of the cloth-like covering, which lie between the embossed springs of the chains. Here, only the chains of the first type have corresponding elongated holes, while the chains of the second type are made without such hole designs. The advantages of such a pocket spring core have already been described in the prior art described at the beginning. Due to the appropriate design, it is possible to insert a chain of the second type through a number of chains of the first type arranged parallel to one another, in which the elongated holes are each coaxially aligned with one another, and to arrange them such that the chains of the second type with their connecting web are inserted through these coaxially aligned elongated holes each sit in an elongated hole, this achieves a firm mechanical bond between the chains, so that a corresponding pocket spring core is formed. It has also already been described that, in order to facilitate the pushing of the chains through the elongated holes, the chains can be pressed together, so that they can then be pushed through the slot-like open elongated holes in a simplified manner. After the springs have sprung open, mechanical locking is achieved. The springs are preferably designed as barrel springs. The pocket spring core produced in this way represents an excellent intermediate product with regard to its cohesion, which can be handled with little care until it is processed into a mattress in its final form. On the basis of the prior art described at the outset, the object of the invention is to create a device for producing such a pocket spring core. To solve this problem, the invention proposes that the device consists essentially of three modules, which are arranged in a row next to each other, that the first, central module comprises a rake-like feeder, by means of which the number of warp first type side by side, parallel to each other and can be aligned with aligned elongated holes and a shot path can be fed, so that a channel-like insertion path spanned by the elongated holes of the adjacent chains is formed for a chain of the second type, that at one end of the insertion path next to the first, middle module, a second module is arranged, by means of which the chain of the second type can be aligned in the correct position with respect to the insertion path and can be compressed in the direction parallel to the central axis of the springs of the chain of the second type to a low height which is equal to or less than the height of the elongated holes of the chains first forming the insertion path that a third module is arranged at the other end of the insertion path next to the first module, which has a means of transport which can be moved coaxially to the insertion path, through which the free end of the chain of the second type located in the second module can be detected and through the insertion path is movable into a position in which the mutually intersecting solo position of the chain of the second type relative to the family of chains of the first type is reached.
Der Begriff "drei Module" ist dabei nicht einschränke zu verstehen, sondern es ist selbstverständlich auch möglich diese drei Module in einer einzigen Vorrichtungsausbildung zu verkörpern oder aber auch die drei Module in mehrere kleinere Baueinheiten zu zerteilen, die lagerichtig zusammengefügt sind.The term "three modules" is not to be understood as restrictive, but it is of course also possible to have these three modules in one To embody device training or to split the three modules into several smaller units that are assembled in the correct position.
Das erste mittlere Modul dient zur parallelen Zuführung einer Anzahl von Ketten erster Art, wobei die Anzahl der Ketten durch das Endmaß des zu fertigenden Taschenfederkernes bestimmt ist. Beispielsweise kann die Anzahl der Länge des entsprechenden Taschenfeder- kernes angepaßt sein oder auch der Breite desselben. Die Ketten erster Art werden als Endloselemente gefertigt und laufen über eine Führungseinrichtung in die rechenartige Zuführvorrichtung ein, wobei am Einlauf der Ketten zur Zuführvorrichtung rollenartige Abweiser oder dergleichen angeordnet sein können, mittels derer die Federelemente der Ketten quasi lotrecht gestellt und in entsprechende U-förmige Führungsschienen der rechenartigen Zuführvorrichtung eingeführt werden. Die jeweils ersten Elemente der parallel zueinander angeordneten Ketten werden mit zueinander fluchtenden Langlöchern ausgerichtet und diese Langlöcher werden so ausgerichtet, daß sie quasi einen Hohlkanal aufspannen, der als Schußpfad für das Zuführen einer Kette zweiter Art genutzt werden kann. Eine entsprechende Kette zweiter Art wird orthogonal zu den Ketten erster Art zugeführt und ausgerichtet und zwar mittels des zweiten Modules, so daß die Kette zweiter Art exakt zu dem Einschubpfad ausgerichtet ist, der durch die Langlöcher der Ketten erster Art gebildet ist. Mittels der Vorrichtung werden die Elemente der Kette zweiter Art auf eine geringe Höhe zusammengepreßt, die vorzugsweise erheblich geringer ist, als der Höhe der zueinander fluchtende Langlöcher der Ketten erster Art ist, die den Einschubpfad bilden.The first middle module is used for the parallel feeding of a number of chains of the first type, the number of chains being determined by the final dimension of the pocket spring core to be manufactured. For example, the number of the length of the corresponding pocket spring core can be adapted or the width of the same. The chains of the first type are manufactured as endless elements and run into the rake-like feed device via a guide device, roller-type deflectors or the like being arranged at the inlet of the chains to the feed device, by means of which the spring elements of the chains are positioned virtually perpendicularly and in corresponding U-shaped guide rails the rake-like feeder are introduced. The respective first elements of the chains arranged parallel to one another are aligned with elongated holes aligned with one another and these elongated holes are aligned such that they virtually span a hollow channel which can be used as a shot path for feeding a chain of the second type. A corresponding chain of the second type is fed and aligned orthogonally to the chains of the first type, specifically by means of the second module, so that the chain of the second type is exactly aligned with the insertion path formed by the elongated holes of the chains of the first type. By means of the device, the elements of the chain of the second type are kept to a minimum Compressed height, which is preferably considerably less than the height of the aligned slots of the chains of the first type, which form the insertion path.
Am dem ersten Modul abgewandten Ende des Einschubkanales ist ein drittes Modul angeordnet, dessen Transportmittel durch den Einschubkanal (gebildet durch die Langlöcher der Ketten erster Art) hindurch verfahrbar ist. Dieses Transpor mi tel nimmt das Ende der im zweiten Modul befindlichen Kette zweiter Art auf und zieht dieses durch den Einschubp in die Sollpos tion, in welcher die Kette zweiter Art die Ketten erster Art kreuzend duchgreift. Bei dem so gefertigten Element sitzen die Federelemente der einen Ketten jeweils in den Lücken, die zwischen den Federelementen der zweiten Kette gebildet sind.At the end of the insertion channel facing away from the first module, a third module is arranged, the transport means of which can be moved through the insertion channel (formed by the elongated holes of the chains of the first type). This transport medium takes up the end of the second type chain in the second module and pulls it through the slot into the target position, in which the second type chain crosses through the first type chains. In the element manufactured in this way, the spring elements of the one chain each sit in the gaps that are formed between the spring elements of the second chain.
Die Vorrichtung ist dabei so ausgebildet, daß jeweils nach dem Durchzug eines Kettenelementes zweiter Art die Kettenelemente erster Art um eine Teilung in dere Längsrichtung vortransportiert werden, so daß die nächste Lochungsreihe von Langlöchern der Ketten erst Art als Durchschubpfad für ein weiteres Elemente zweiter Art zur Verfügung steht.The device is designed in such a way that after the passage of a chain element of the second type, the chain elements of the first type are transported forward by one division in their longitudinal direction, so that the next row of perforations of elongated holes of the chain is only available as a push-through path for another element of the second type stands.
Diese Fertigung kann endlos erfolgen. Es ist aber auch möglich, die jeweils gebildetenThis production can take place endlessly. But it is also possible to choose the one that is formed

In den Zeichnungen ist eine erfindungsgemäße Vorrichtung zur Herstellung eines Taschenfederkernes gezeigt. Ein solcher Taschenfederkern besteht aus einer Vielzahl von parallelen Ketten eingetaschter Federn, wobei jede Kette eine fortlaufende Reihe von Federn aufweist, die von einer tuchartigen Umhüllung eng ummantelt und durch diese über Verbindungsstege miteinander verbunden sind. Die so gebildeten Taschen eine Kette weisen zur Abgrenzung der Federn quer verlaufende Verbindungsnahte auf, die parallel zu den Langsachsen der Federn gerichtet sind. Die benachbarten Ketten sind im Endzustand mechanisch miteinander verbunden, wozu jeweils eine erste Anzahl von Ketten im Bereich der Verbindungsnahte mit gleich¬ gerichteten Schlitzen versehen und mit Abstand voneinander zueinander parallel gerichtet angeordnet sind und eine zweite Anzahl von Ketten rechtwinklig zu der ersten Anzahl von Ketten gerichtet parallel zu und mit Abstand voneinander angeordnet sind. Die ersten und zweiten Ketten sind in Zeilen und Spalten angeordnet, wobei die zwischen parallelen Reihen gebildeten Abstände durch in die Lucken der Elemente der ersten Anzahl von Ketten eingesetzte Elemente der zweiten Anzahl von Ketten ausgefüllt sind. Auf diese Weise sind die Elemente jeder folgenden Zeile oder Spalte versetzt zueinander angeordnet.In the drawings, an inventive device for producing a pocket spring core is shown. Such a pocket spring core consists of a plurality of parallel chains of pocketed springs, each chain having a continuous row of springs which are closely covered by a cloth-like sheath and are connected to one another by connecting webs. The pockets thus formed have a chain across to delimit the springs running connecting seams, which are directed parallel to the longitudinal axes of the springs. In the final state, the adjacent chains are mechanically connected to one another, for which purpose a first number of chains in the area of the connecting seam are provided with slots oriented in the same direction and arranged parallel to one another at a distance from one another, and a second number of chains is directed at right angles to the first number of chains are arranged parallel to and at a distance from one another. The first and second chains are arranged in rows and columns, the distances formed between parallel rows being filled by elements of the second number of chains inserted into the gaps of the elements of the first number of chains. In this way, the elements of each subsequent row or column are staggered.
Wie insbesondere aus Figur 3 ersichtlich, sind die Schlitze als lediglich in dem Bereich offene Langlochri 1 ausgebildet, der zwischen den durch die Stirnflachen der eingetaschten Federn 2 gebildeten beiden Ebenen liegt. Diese mit Langlochern 1 versehenen Ketten sind die Ketten erster Art 3. Jede Kette der zweiten Art 4 st im Endzustand jeweils die in Flucht zueinander ausgerichteten Langlocher 1 der aus der Ketten erster Art 3 gebildeten Kettenschar durchgreifend angeordnet, wobei im Bereich jedes Langlochdurchgrlffes (bei 1) ein Bereich einer Verbindungsnaht 5 der Kette zweiter Art 4 angeordnet ist.As can be seen in particular from FIG. 3, the slots are designed as slot slots 1 which are only open in the area which lies between the two planes formed by the end faces of the pocketed springs 2. These chains provided with elongated holes 1 are the chains of the first type 3. In the final state, each chain of the second type 4 is arranged so as to pass through the aligned elongated holes 1 of the coulter set formed from the chains of the first type 3, with each elongated hole penetrating area (at 1 ) A region of a connecting seam 5 of the chain of the second type 4 is arranged.
Die Vorrichtung besteht im wesentlichen aus drei Modulen 6, 7, 8, die in Reihe nebeneinander angeordnet sind, wie insbesondere aus Figur 4 ersichtlich ist. Das erste, mittlere Modul 6 weist, wie insbesondere aus Figur 1 ersichtlich, eine rechenartige Zuführvorrichtung 9 auf, mittels derer eine entsprechende Anzahl von Ketten erster Art 3 nebeneinander und parallel zueinander sowie mit zueinander fluchtenden Langlöchern 6 ausrichtbar und einem Schußpfad zuführbar sind, so daß jeweils ein durch die Langlöcher 1 der benachbarten Ketten 3 aufgespannter kanalartiger Einschubpfad 10 für eine Kette 4 zweiter Art gebildet ist. Die Anordnung und Zuführung der Ketten erster Art 3 erfolgt so, daß jeweils die in Zuführrichtung 11 vornliegende erste Reihe von Langlöchern 1 koaxial zum Einschubpfad 10 ausgerichtet ist. Am einen Ende des Einschubpfades 10 (in Zeichnungsfigur 1 und 4 links) ist neben dem ersten mittleren Modul 6 ein zweites Modul 7 angeordnet. Mittels dieses Moduls 7 ist die Kette 4 zweiter Art lagerichtig zum Einschubpfad 10 ausrichtbar und in Richtung parallel zur Mittelachse der Federn der Kette 4 zweiter Art auf eine geringe Höhe zusammenpreßbar, die geringer ist als die Höhe der zueinander fluchtenden, den Einschubpfad 10 bildenden Langlöcher 1 der Ketten 3 erster Art.The device essentially consists of three modules 6, 7, 8, which are arranged in a row next to one another are, as can be seen in particular from Figure 4. The first, middle module 6 has, as can be seen in particular in FIG. 1, a rake-like feed device 9, by means of which a corresponding number of chains of the first type 3 can be aligned next to and parallel to one another and with elongated holes 6 aligned with one another and can be fed to a shot path, so that In each case a channel-like insertion path 10 spanned by the elongated holes 1 of the adjacent chains 3 is formed for a chain 4 of the second type. The chains of the first type 3 are arranged and fed in such a way that the first row of elongated holes 1 lying forward in the feed direction 11 is aligned coaxially with the insertion path 10. At one end of the insertion path 10 (in the drawing figures 1 and 4 on the left), a second module 7 is arranged next to the first middle module 6. By means of this module 7, the chain 4 of the second type can be aligned in the correct position with respect to the insertion path 10 and can be compressed in the direction parallel to the central axis of the springs of the chain 4 of the second type to a small height which is less than the height of the elongated holes 1 which form the insertion path 10 and are aligned with one another of chains 3 of the first kind.
Am anderen Ende des Einschubpfades 10 (in Zeichnungsfigur 1 und 4 rechts) neben dem ersten Modul 6 ist ein drittes Modul 8 angeordnet, das ein Transportmittel 12 aufweist, welches koaxial zum Einschubpfad 10 durch diesen und die entsprechendenAt the other end of the insertion path 10 (in the drawing figures 1 and 4 on the right) next to the first module 6 there is a third module 8 which has a means of transport 12 which is coaxial to the insertion path 10 through it and the corresponding ones
Langlöcher 1 hindurch verfahrbar ist und mittels dessen das freie Ende der im zweiten Modul 7 befindlichen Kette 4 zweiter Art erfaßbar und durch den Einschubpfad 10 in eine Position bewegbar ist, in der die einander kreuzende Sollposition der Kette zweiter Art relativ zur Schar der Ketten erster Art 3 erreicht ist.Elongated holes 1 can be moved through and by means of which the free end of those in the second module 7 Chain 4 of the second type can be detected and moved through the insertion path 10 into a position in which the intersecting desired position of the chain of the second type relative to the family of chains of the first type 3 has been reached.
Das erste mittlere Modul 6 weist einen AblagetischThe first middle module 6 has a storage table
14 für die aufrechtstehend angeordneten Ketten 3 erster Art auf, der im Bereich des Einschubpfades 10 eine unterhalb des Einschubpfades 10 angeordnete und parallel zu dessen LangserStreckung gerichtete erste Fuhrungsflache 15 aufweist, wobei oberhalb dieser Fuhrungsflache 15 eine balkenartige, parallel zur ersten Fuhrungsflache 15 gerichtete zweite Fuhrungsflache 16 angeordnet ist. Wahrend die erste Fuhrungsflache 15 ein starres Element des Modules14 for the upright arranged chains 3 of the first type, which in the region of the insertion path 10 has a first guide surface 15 which is arranged below the insertion path 10 and is parallel to its longitudinal extension, above which guide surface 15 a bar-like second guide surface which is directed parallel to the first guide surface 15 16 is arranged. While the first guide surface 15 is a rigid element of the module
6 ist, ist die zweite Fuhrungsflache 16 in Richtung des Pfeiles 17 verfahrbar. Hierzu können beispiels e1se pneumatische Stellelemente 18 an einem aschinengestell 19 gehaltert sein, mittels derer eine Verstellung der zweiten Fuhrungsflache zur ersten Fuhrungsflache6, the second guide surface 16 can be moved in the direction of arrow 17. For this purpose, for example, pneumatic actuating elements 18 can be held on an machine frame 19, by means of which an adjustment of the second guide surface to the first guide surface can be carried out
15 hin und von dieser weg möglich ist.15 to and from this is possible.
Am mittleren Modul 6 sind zudem PositIonlermit te1 1,11 angeordnet, mittels derer die zueinander parallelen Ketten 3 erster Art schrittweise so positionierbar sind, daß jeweils der zwischen zwei eingetaschen Federn 2 einer Kette 3 befindliche, mit Lochung 1 versehene Bereich mittig des Einschubpfades 10 und der Fuhrungsflache 15, 16 ausrichtbar ist. Auf diese Weise sind die entsprechenden LochungenOn the middle module 6 there are also positions 1, 11, 11, by means of which the mutually parallel chains 3 of the first type can be gradually positioned such that the area between two pocketed springs 2 of a chain 3, provided with perforation 1, in the middle of the insertion path 10 and the guide surface 15, 16 can be aligned. In this way, the corresponding perforations
1 der Ketten erster Art 3 im Bereich des Einschubpfades 10 in Flucht zueinander und koaxial zueinander ausgerichtet . Die Positioniermittel I, II können zudem Streckmittel umfassen, mittels derer die Ketten 3 erster Art im Bereich der den Einschubpfad 10 bildenden Lochungen 1 in Längserstreckungsrichtung der Ketten 3 quer von der den Einschubpfad bildenden Ebene weggerichtet streckbar und spannbar sind oder durch sie zumindest quer zum Einschubpfad 10 gestreckt gehalten sind.1 of the chains of the first type 3 in the region of the insertion path 10 in alignment with one another and aligned coaxially with one another. The positioning means I, II can also comprise stretching means, by means of which the chains 3 of the first type can be stretched and tensioned in the area of the perforations 1 forming the insertion path 10 in the longitudinal direction of extension of the chains 3, transversely from the plane forming the insertion path, or at least transversely to the insertion path 10 are kept stretched.
Wie aus der Abfolge der Figuren 2 und 4 bzw. 3 und 5 ersichtlich, ist die zweite Führungsfläche 16 bei positionierten Lochungsbereichen 1 der Ketten 3 erster Art auf die mit den Lochungen 1 versehene Streckbereiche der Ketten 3 absenkbar, so daß die Ketten 3 erster Art bei abgesenkter Führungsfläche 16 gemäß Darstellung in Figur 4 und 5 in Richtung der Mittellängsachse ihrer Federn 2 zusammengepreßt und in der Höhe reduziert sind, wodurch die Lochungen 1 erweitert sind, wie insbesondere aus Figur 5 ersichtlich .As can be seen from the sequence of FIGS. 2 and 4 or 3 and 5, the second guide surface 16, when the perforated areas 1 of the chains 3 of the first type are positioned, can be lowered onto the stretched areas of the chains 3 provided with the perforations 1, so that the chains 3 of the first type with the guide surface 16 lowered, as shown in FIGS. 4 and 5, compressed in the direction of the central longitudinal axis of their springs 2 and reduced in height, as a result of which the perforations 1 are widened, as can be seen in particular from FIG. 5.
Vorzugsweise weisen die Führungsflächen 15, 16 im Bereich des Querdurchlaufs der Ketten erster Art 3 Nuten oder dergleichen auf, deren Breite mindestens etwas größer ist, als der Breite des gelochten Stegbereiches der Ketten 3 zwischen den benachbarten Federn 2 eine jeden Kette 3 entspricht. Hierdurch sind die gemäß Figur 5 oberen und unteren Stegbereiche des die Lochung 1 aufweisenden Steges im Bereich des Einschubpfades quasi versenkt in den Führungsflächen 15, 16 angeordnet, so daß durch diese Stegbereiche kein Hindernis beim Durchschub des Kettenelementes 4 zweiter Art gebildet ist. Vielmehr kann die Kette zweiter Art 4 problemlos durch die Lochungen 1 hindurchgezogen werden.The guide surfaces 15, 16 preferably have 3 grooves or the like in the area of the transverse passage of the chains of the first type, the width of which is at least somewhat larger than the width of the perforated web area of the chains 3 between the adjacent springs 2 corresponds to each chain 3. As a result, the upper and lower web areas according to FIG. 5 of the web having the perforation 1 are arranged virtually sunk in the guide surfaces 15, 16 in the region of the insertion path, so that no obstacle to pushing through the chain element 4 of the second type is formed by these web areas. Rather, the chain of the second type 4 can easily be pulled through the perforations 1.
Die Fuhrungsflachen 15, 16 können auf den einander zugewandten Flachen mit reibungsmindernden Belagen versehen sein. Es ist auch möglich auf die Fuhrungs- flachen 15, 16 reibungsmindernde Elemente aufzusetzten , zwischen denen dann die entsprechenden Nuten (quer zum Einschubpfad 10) gebildet sind. Die Positioniermittel 1,11, die als oberhalb des Tisches 14 und der Fuhrungflachen 15 angeordnete Balken ausgebildet sind, weisen Halteelemente auf. Diese Halteelemente sind in den Figuren 10 und 11 im einzelnen gezeigt. Von diesen Halteelementen, die über die gesamte Lange der Balken angeordnet sind, die die Positloniermittel I, II bilden, sind erste Hal eelemente 20 so angeordnet, daß sie in die dem Einschubpfad 10 benachbarten Kreuzungsbereiche 21 der schon gekreuzten Ketten erster und zweiter Art eingreifen, wie in Figur 11 rechts gezeigt. Diese Position befindet sich also in Vorschubrichtung 11 der Kettenelemente 3 erster Art jenseits des Einschubpfades 10. Es sind ferner zweite Halteelemente 22 angeordnet, die die zwischen jeweils zwei benachbarten Federn 2 einer Kette erster Art 3 befindlichen Stegbereiche, die die Lochungen 1 aufweisen, gabelartig übergreifen. Diese in Vielfachanordnung vorgesehenen Halteelemente 20, 22 sind jeweils parallel beidseits des Einschubpfades 10 angeordnet und an entsprechenden Traversen derThe guide surfaces 15, 16 can be provided on the mutually facing surfaces with friction-reducing coverings. It is also possible to place friction-reducing elements on the guide surfaces 15, 16, between which the corresponding grooves (transverse to the insertion path 10) are then formed. The positioning means 1, 11, which are designed as bars arranged above the table 14 and the guide surfaces 15, have holding elements. These holding elements are shown in detail in FIGS. 10 and 11. Of these holding elements, which are arranged over the entire length of the bars that form the positioning means I, II, first holding elements 20 are arranged such that they engage in the crossing regions 21 of the already crossed chains of the first and second types adjacent to the insertion path 10, as shown in Figure 11 on the right. This position is therefore in the direction of advance 11 of the chain elements 3 of the first type beyond the insertion path 10. There are also second holding elements 22 which overlap the web areas located between two adjacent springs 2 of a chain of the first type 3 and which have the perforations 1 in a fork-like manner . These holding elements 20, 22, which are provided in a multiple arrangement, are each arranged in parallel on both sides of the insertion path 10 and on corresponding crossbars
Elemente 1,11 gehaltert. Sie werden taktweise bewegt und abgesenkt, wie anhand der Figur 11 verdeutlicht ist . Bei der Darstellung gemäß Figur 11 befinden sich die Haltelemente 20,22 in abgesenkter Eingriffsposition, wobei die Elemente I und II einschließlich der sie verbindenden Traverse entsprechend dem Bewegungspfeil 26 abwärts Verfahren sind. Zum Transport und zur Positionierung der Ketten 3 erster Art in Vorschubrichtung 11 sind die entsprechenden Elemente 20, 22 um einen Lochungsabstand der Lochungen 1 einer Kette 3 quer zum Einschubpfad 10 in Richtung des Pfeiles 23 verstellbar. Bei Erreichen der Sollposition werden die Elemente 20, 22 entsprechend dem Bewegungspfeil 24 angehoben in eineElements 1.11 supported. They are moved and lowered in cycles, as is shown in FIG. 11. In the illustration according to FIG. 11, the holding elements 20, 22 are in the lowered engagement position, the elements I and II including the cross member connecting them being a downward movement in accordance with the movement arrow 26. For transporting and positioning the chains 3 of the first type in the feed direction 11, the corresponding elements 20, 22 can be adjusted transversely to the insertion path 10 in the direction of the arrow 23 by a distance between the perforations 1 of a chain 3. When the desired position is reached, the elements 20, 22 are lifted into one in accordance with the movement arrow 24
Außereingriffposition und anschließend entgegen der Vorschubrichtung 11 der Ketten 3 erster Art um einen Lochungsabstand in Richtung des Pfeiles 25 verstellt. In dieser Endposition werden die Halteelemente entsprechend dem Bewegungspfeil 26 abgesenkt woran sich wieder die Bewegungen in Richtung des Bewegungspfeiles 23 anschließt. Dieser Bewegungsablauf erfolgt taktweise, wobei jeweils durch die lagerichtig positionierten Lochungen 1 das Kettenelement 4 zweiter Art hindurchgezogen wird. Wie insbesondere aus den Figuren 8 und 9 ersichtlich ist vor dem zweiten, in Zuführrichtung der Ketten 4 zweiter Art vor dem Einführende des Einschubpfades 10 angeordneten Modul 7 eine Transportvorrichtung 27 angeordnet, mittels derer eine Kette zweiter Art 4 dem zweiten Modul 7 zuführbar ist. Die Transportvorrichtung 27 besteht aus zwei beidseits der Kette 4 angeordneten kettenartigen oder bandartigen Förderelementen, mittels derer die Kette 4 lagerichtig positioniert und transportiert wird. Zwischen der Transportvorrichtung 27 und dem zweiten Modul 7 ist eine Trennvorrichtung 28 angeordnet, mittels derer das in das zweite Modul 7 transportierte Ende des endlos Kettenstranges der Kette zweiter Art 4 im Bereich eines zwischen zwei Federn befindlichen Steges 5 durchtrennbar ist. Die Trennvorrichtung ist mit einer Steuerung gekoppelt, mittels derer die Lange des durchgelaufenen Kettenstanges erfaßt wird, wobei nach Durchlauf der entsprechenden Lange die Trennvorrich ung 28 in Betrieb gesetzt wird, so daß das durchgelaufene Ende der Kette 4 abgetrennt wird. Das zweite Modul 7 weist eine zweite Transportvorrichtung 29 auf, mittels derer das abgelangte Kettenteilstuck der Kette 4 bis in Sollposition im zweiten Modul 7 in Richtung auf den Einschubpfad 10 des ersten Moduls 6 transportierbar ist. Diese TransportVorrichtung 29 bildet die Aufstandsebene für die orthogonal zu dieser ausgerichteten Feder der Kette 4 zweiter Art. Am zweiten Modul 7 ist oberhalb der Aufstandsebene (gebildet durch das Element 29) eine Traverse 30 gehaltert, die in Richtung des Bewegungspfeiles 31 mittels pneumatischer Stellelemente 32 verstellbar ist. Die Traverse 30 ist somit zur Aufstandsebene hin und von dieser weg verfahrbar. Mittels dieserDisengaged position and then against the feed direction 11 of the chains 3 of the first type by a hole spacing in the direction of arrow 25. In this end position, the holding elements are lowered in accordance with the movement arrow 26, which is followed by the movements in the direction of the movement arrow 23. This sequence of movements takes place in cycles, the chain element 4 of the second type being pulled through the correctly positioned perforations 1. As can be seen particularly from FIGS. 8 and 9, a transport device 27 is arranged in front of the second module 7 arranged in the feed direction of the chains 4 of the second type before the insertion of the insertion path 10, by means of which a chain of the second type 4 can be fed to the second module 7. The transport device 27 consists of two chain-like or belt-like conveying elements arranged on both sides of the chain 4, by means of which the chain 4 is positioned and transported in the correct position. A separating device 28 is arranged between the transport device 27 and the second module 7, by means of which the end of the endless chain strand of the chain of the second type 4, which is transported into the second module 7, can be severed in the region of a web 5 located between two springs. The separating device is coupled to a controller, by means of which the length of the chain rod that has passed through is detected, the separating device 28 being put into operation after passage of the corresponding length, so that the end of the chain 4 that has passed through is separated. The second module 7 has a second transport device 29, by means of which the cut chain section of the chain 4 can be transported in the desired position in the second module 7 in the direction of the insertion path 10 of the first module 6. This transport device 29 forms the contact plane for the spring of the chain 4 of the second type which is oriented orthogonally to this. A crossmember 30 is mounted on the second module 7 above the contact plane (formed by the element 29) and can be adjusted in the direction of the movement arrow 31 by means of pneumatic adjusting elements 32 is. The traverse 30 can thus be moved towards and away from the contact plane. By means of this
Traverse 30 kann das abgelangte und in Sollposition befindliche Teilstuck der Kette zweiter Art 4 unter Reduzierung der Federnhohe zusammengepreßt werden, wie aus der Abfolge der Figuren 7 und 8 ersichtlich. Sobald die Kette 4 aus dem Modul 7 in das Modul 6 übergeben worden ist, kann die Traverse 30 in die Ausgangsposition (in Zeichnungsfigur 8 nach oben) entsprechend der Position gemäß Figur 7 verfahren werden, in welcher das folgende Ende der Kette 4 zweiter Art in den Freiraum zwischen Ausgangsebene und Traverse 30 hinein transportiert werden kann.Traverse 30, the part of the chain of the second type 4 which has been cut to length and in the desired position can be pressed together while reducing the spring height, as can be seen from the sequence of FIGS. 7 and 8. As soon as the chain 4 has been transferred from the module 7 to the module 6, the traverse 30 can be in the starting position (upwards in the figure 8) are moved according to the position according to FIG. 7, in which the following end of the chain 4 of the second type can be transported into the free space between the starting level and the cross member 30.
Anhand der Figur 2, 4, 6 ist das dritte Modul 8 erläutert. Das dritte Modul 8 weist als Transportmittel 12 ein in den Einschubkanal 10 der im ersten Modul 6 angeordneten Ketten 3 erster Art entgegen Zufuhrrichtung der Kette zweiter Art 4 verfahrbahres stangenformiges Element auf, das an seinem in Verfahrrichtung vorderen Ende eine Spannzange 33 aufweist. Nach der lagerichtigen Anordnung der Kettenelemente 3 erster Art mit den entsprechenden Langlochern 1 koaxial zum Einschubkanal 10 kann das Transportmittel 12 aus der Position gemäß Figur 2 in die Position gemäß Figur 4 verfahren werden. Die Spannzange 33 wird erst geöffnet, sobald die Spannzange die in dem Modulbauteil 7 befindliche Kette 4 zweiter Art erreicht. Die Zangenbacken der Zange 33 werden dann geöffnet und unter weiterem Vorschub der Transportvorrichtung 12 über das letzte Glied der Kette 4 geschoben und dann geschlossen. Anschließend verfahrt die Transporteinrichtung 12 aus der Position gemäß Figur 4 in die Position gemäß Figur 6. In dieser Position wird die Spannzange 33 vorüber ehend geöffnet und dann wieder geschlossen. Die Transportvorrichtung 12 kann dann aus der Position gemäß Figur 6 noch weiter nach rechts verfahren werden.The third module 8 is explained with reference to FIGS. 2, 4, 6. The third module 8 has, as a means of transport 12, a rod-shaped element which is movable in the insertion channel 10 of the chains 3 of the first type arranged in the first module 6 against the feed direction of the chain of the second type 4 and which has a collet 33 at its front end in the direction of travel. After the correct arrangement of the chain elements 3 of the first type with the corresponding elongated holes 1 coaxial to the insertion channel 10, the transport means 12 can be moved from the position according to FIG. 2 to the position according to FIG. The collet 33 is only opened as soon as the collet reaches the chain 4 of the second type located in the module component 7. The pliers jaws of the pliers 33 are then opened and pushed over the last link of the chain 4 with further advancement of the transport device 12 and then closed. The transport device 12 then moves from the position shown in FIG. 4 to the position shown in FIG. 6. In this position, the collet 33 is opened and then closed again. The transport device 12 can then be moved even further to the right from the position according to FIG. 6.
