Description

Die Erfindung betrifft eine Wirkwerkzeugbarre mit Wirkwerkzeugen, die in Aufnahmenuten einer Wirkwerkzeugaufnahme angeordnet sind, und mit einer Klemmdeckelanordnung, die die Wirkwerkzeuge in den Aufnahmenuten sichert, wobei jedes Wirkwerkzeug eine Rückseite, die einem Nutgrund benachbart ist, eine Vorderseite, die aus der Aufnahmenut herausragt, und zwei Flanken aufweist, die die Vorderseite und die Rückseite miteinander verbinden, und die Klemmdeckelanordnung auf die Vorderseite wirkt, wobei die Wirkwerkzeuge mit ihrer Vorderseite jeweils in je eine Deckelnut hinein ragen, wobei die Deckelnut in einer Unterlage ausgebildet ist, die zwischen der Klemmdeckelanordnung und den Wirkwerkzeugen angeordnet ist.The invention relates to a knitting tool bar with knitting tools, which are arranged in receiving grooves of a knitting tool holder, and with a clamping lid arrangement, which secures the knitting tools in the receiving grooves, each knitting tool having a back side which is adjacent to a groove bottom, a front side, which protrudes from the receiving groove. and has two flanks connecting the front and the back, and the clamping cover assembly acts on the front, wherein the knitting tools each project with its front in a respective lid groove, wherein the lid groove is formed in a pad between the clamping lid assembly and the knitting tools is arranged.

Ferner betrifft die Erfindung ein Verfahren zum Montieren von Wirkwerkzeugen in einer Wirkwerkzeugaufnahme einer Wirkwerkzeugbarre, bei dem man die Wirkwerkezuge in Aufnahmenuten der Wirkwerkzeugaufnahme einlegt und durch eine Klemmdeckelanordnung sichert, wobei man die Wirkwerkzeuge an ihrem aus den Aufnahmenuten herausragenden Abschnitt jeweils in Deckelnuten anordnet, die in einer Unterlage vorgesehen sind, die zwischen der Klemmdeckelanordnung und den Wirkwerkzeugen angeordnet ist, wobei man die Deckelnuten vor Ort während der Montage erzeugt.Furthermore, the invention relates to a method for assembling knitting tools in a knitting tool receiving a knitting tool bar, in which one inserts the active trains in receiving grooves of the knitting tool holder and secures by a clamping lid assembly, wherein the knitting tools at their protruding from the grooves projecting portion each in lid grooves, which in a pad are provided, which is arranged between the clamping lid assembly and the knitting tools, wherein the lid grooves produced on site during assembly.

Eine derartige Wirkwerkzeugbarre und ein derartiges Verfahren sind aus der US 2 005 674 A bekannt. Diese zeigt eine Vorrichtung zum Montieren von Nadeln oder dergleichen, bei der die Nadeln in Aufnahmenuten einer Wirkwerkzeugaufnahme durch Klemmdeckel gehalten werden. Die Klemmdeckel weisen eine elastische Unterlage auf, in welche die Nadelschäfte während der Montage eingedrückt werden, die zusätzlich mit einem feuchtigkeitsabweisenden Mittel getränkt sind, das sich an den Nadeln anlagert, um Rost zu vermeiden.Such a Wirkwerkzeugbarre and such a method are from the US 2 005 674 A known. This shows a device for mounting needles or the like, in which the needles are held in receiving grooves of a knitting tool holder by clamping lid. The clamping lids have an elastic base into which the needle shanks are pressed during assembly, which are additionally impregnated with a moisture-repellent agent, which attaches to the needles to prevent rust.

Die DD 2169 A zeigt eine weitere Wirkwerkzeugbarre. Ein Teil eines Barrenkopfes, der als Wirkwerkzeugaufnahme dient, und der Deckel sind entsprechend der Nadelteilung mit Ausfräsungen versehen.The DD 2169 A shows another knitting tool bar. A part of a Barrenkopfes, which serves as knitting tool holder, and the lid are provided according to the needle pitch with cutouts.

EP 0 244 656 A1 zeigt eine Einspannvorrichtung für Nadeln, insbesondere Häkelnadeln. Zum sicheren Einspannen der Nadelschäfte dienen einander gegenüberliegende Nuten, die in einen Unterteil und in einen Oberteil gefräst sind. EP 0 244 656 A1 shows a clamping device for needles, in particular crochet hooks. For safe clamping of the needle shanks serve opposite grooves, which are milled into a lower part and in an upper part.

Eine weitere Wirkwerkzeugbarre ist beispielsweise aus EP 2 025 786 A1 bekannt. Die Wirkwerkzeuge, beispielsweise Wirknadeln, die auch als Arbeitsnadeln bezeichnet werden, sind parallel zueinander entlang der Längsrichtung der Wirkwerkzeugbarre angeordnet. Wenn ein Wirkwerkzeug ersetzt werden muss, wird die Klemmdeckelanordnung gelöst, so dass das auszutauschende Wirkwerkzeug aus seiner Aufnahmenut herausgenommen und ein neues Wirkwerkzeug eingelegt werden kann. Danach wird die Klemmdeckelanordnung wieder montiert und die Wirkwerkzeugbarre ist wieder betriebsbereit.Another knitting tool bar is for example off EP 2 025 786 A1 known. The knitting tools, such as knitting needles, which are also referred to as working needles are parallel to each other along the Longitudinal direction of the knitting tool bar arranged. If a kneading tool needs to be replaced, the clamping cover assembly is released so that the knitting tool to be exchanged can be removed from its receiving groove and a new knitting tool can be inserted. Thereafter, the clamping cover assembly is mounted again and the Wirkwerkzeugbarre is ready for use again.

DE 198 55 711 C2 zeigt eine Vorrichtung zur Befestigung von Wirkelementen an der Barre einer Kettenwirkmaschine, bei der die Wirkelemente durch eine Klemmdeckelanordnung an der Barre gehalten werden. DE 198 55 711 C2 shows a device for attachment of active elements to the bar of a warp knitting machine, in which the active elements are held by a clamping cover assembly on the bar.

DE 41 31 809 A1 zeigt eine Vorrichtung zum Einspannen und Führen von Häkelnadeln für eine Häkelmaschine, bei der in einem Unterteil und einem Klemmdeckel dreieckförmige Nuten eingefräst sind, die einander gegenüberliegen. DE 41 31 809 A1 shows a device for clamping and guiding crochet hooks for a crocheting machine, in which are milled in a lower part and a clamping lid triangular grooves which face each other.

DE 10 2006 004 099 B3 beschreibt ein Wirkelement einer Kettenwirkmaschine und eine zugehörige Barre. Die Nadeln weisen einen Querschnitt auf, der an den Querschnitt von Nuten angepasst ist, in denen sie angeordnet sind. Dieser Querschnitt weist mindestens eine geneigte Flanke auf. DE 10 2006 004 099 B3 describes an active element of a warp knitting machine and an associated barre. The needles have a cross-section adapted to the cross section of grooves in which they are arranged. This cross section has at least one inclined flank.

Bei der Herstellung von Wirkwaren werden Kettfäden miteinander vermascht. In Abhängigkeit von der zu erzeugenden Wirkware können hier relativ hohe mechanische Spannungen auftreten, die von den Wirkwerkzeugen aufgenommen werden müssen. Dementsprechend müssen diese Wirkwerkzeuge auch stabil genug ausgebildet sein und auch die Wirkwerkzeugaufnahme muss in der Lage sein, die auftretenden Kräfte aufzunehmen. Dies führt in vielen Fällen zu einer Zunahme der zu bewegenden Masse, was sich negativ auf die Arbeitsgeschwindigkeit der Kettenwirkmaschine auswirkt.In the production of hosiery warp threads are meshed with each other. Depending on the knitted fabric to be produced here relatively high mechanical stresses can occur that of the knitting tools must be included. Accordingly, these knitting tools must also be made stable enough and also the knitting tool holder must be able to absorb the forces occurring. This leads in many cases to an increase in the mass to be moved, which has a negative effect on the operating speed of the warp knitting machine.

Der Erfindung liegt die Aufgabe zu Grunde, mit einfachen Mitteln eine hohe Belastbarkeit der Wirkwerkzeuge zu erreichen.The invention is based on the object, with simple means to achieve a high load capacity of the knitting tools.

Diese Aufgabe wird bei einer Wirkwerkzeugbarre der eingangs genannten Art dadurch gelöst, dass die Deckelnut in einer Unterlage ausgebildet ist, die zwischen der Klemmdeckelanordnung und den Wirkwerkzeugen angeordnet ist und die Unterlage zumindest im Bereich der Wirkwerkzeuge aus einem verformbaren Material mit Verfestigungsmechanismus gebildet ist.This object is achieved with a knitting tool bar of the type mentioned above in that the lid groove is formed in a pad which is disposed between the clamping lid assembly and the knitting tools and the pad is formed at least in the field of knitting tools of a deformable material with hardening mechanism.

Bei einer derartigen Ausgestaltung wird das Wirkwerkzeug also nicht nur von seiner Rückseite aus an den Flanken abgestützt, sondern auch von seiner Vorderseite aus. Über die Höhe, d. h. den Bereich zwischen der Vorderseite und der Rückseite des Wirkwerkzeugs gesehen, wird das Wirkwerkzeug also in zwei Bereichen abgestützt und nicht nur, wie bisher, in einem Bereich.In such an embodiment, the knitting tool is thus supported not only from its back on the flanks, but also from its front. About the height, ie the area between the front and seen the back of the kneading tool, the kneading tool is therefore supported in two areas and not only, as before, in a range.

Die Klemmdeckelanordnung kann gegenüber existierenden Klemmdeckelanordnungen praktisch unverändert beibehalten werden. Bei der Montage der Klemmdeckelanordnung wird die Unterlage einfach zwischen den Wirkwerkzeugen und der Klemmdeckelanordnung positioniert.The clamp cover assembly can be maintained virtually unchanged from existing clamp cover assemblies. When mounting the clamp cover assembly, the pad is simply positioned between the knitting tools and the clamp cover assembly.

Beispiele für Materialien mit Verfestigungsmechanismus sind chemisch härtende Polymere und auch Polymere mit Verfestigung durch Erstarren einer Schmelze oder Entweichen eines Lösemittels. Die Deckelnuten können dann vor Ort erzeugt werden. Die Unterlage wird in einem Zustand auf die Wirkwerkzeuge aufgelegt, in der sie noch verformbar ist. Wenn die Klemmdeckelanordnung montiert wird, dann wird die Unterlage auf die Wirkwerkzeuge gepresst, so dass sich die Deckelnuten automatisch ausbilden. Im Grunde wird ein Teil der Unterlage in den Bereich zwischen den Wirkwerkzeugen verdrängt. Wenn sich dann das Material verfestigt, ergibt sich eine ideale Formanpassung der Unterlage an die Wirkwerkzeuge und die Unterlage kann die Wirkwerkzeuge somit auch formschlüssig stützen. Wenn die Nuten vor Ort erzeugt werden, kann man sich eine mechanische Bearbeitung der Nuten sparen. Die Fertigung ist außerordentlich einfach, weil man keine Doppelpassung berücksichtigen muss, sondern die Positionen der Wirkelemente nur durch die entsprechenden Nuten in der Barre vorgegeben werden. Man kann hierbei in Kauf nehmen, dass die Unterlage nach lösen der Klemmdeckelanordnung und Austausch einer größeren Anzahl von Wirkwerkzeugen nicht mehr, wie zuvor, auf die Wirkwerkzeuge passt. In diesem Fall muss die Unterlage bei einer erneuten Montage erneuert werden. Die Unterlage ist dann sozusagen als Wegwerfelement ausgebildet. Die Unterlage kann hierbei komplett aus dem Material mit Verfestigungsmechanismus bestehen. Sie kann aber auch eine Beschichtung aus dem Material mit Verfestigungsmechanismus haben.Examples of materials with solidification mechanism are chemically curing polymers and also polymers with solidification by solidification of a melt or the escape of a solvent. The lid grooves can then be produced on site. The pad is placed in a state on the knitting tools in which it is still deformable. When the clamp cover assembly is mounted, then the pad is pressed onto the knitting tools, so that the lid grooves form automatically. Basically, a part of the pad is displaced into the area between the knitting tools. If then solidifies the material, there is an ideal shape adaptation of the pad to the knitting tools and the pad can support the knitting tools thus also form fit. If the grooves are produced on site, one can save on mechanical machining of the grooves. The production is extremely simple, because you do not have to consider a double fit, but the positions of the active elements are specified only by the corresponding grooves in the bar. One can accept in this case that the pad after loosening the clamping lid assembly and exchange a larger number of knitting tools no longer, as before, fits on the knitting tools. In this case, the base must be renewed when reassembling. The pad is then formed as a throwaway element, so to speak. The pad can here completely consist of the material with hardening mechanism. But it can also have a coating of the material with hardening mechanism.

Das Material mit Verfestigungsmechanismus erhält erst während der Montage der Klemmdeckelanordnung oder nach der Montage der Klemmdeckelanordnung seine feste Form. Das Material kann chemisch härtbar sein. Man kann auch vorsehen, dass das Material durch Beaufschlagung mit einer Strahlung, beispielsweise UV-Strahlung aushärtet. Man kann auch vorsehen, dass nach Abziehen einer Schutzfolie eine Polymerreaktion ausgelöst wird. Diese Aufzählung ist nicht abschließend.The material with hardening mechanism receives its solid form only during assembly of the clamping lid assembly or after assembly of the clamping lid assembly. The material can be chemically curable. It can also be provided that the material cures by exposure to radiation, for example UV radiation. It can also be provided that after removal of a protective film, a polymer reaction is triggered. This list is not exhaustive.

Vorzugsweise ist die Unterlage mit der Klemmdeckelanordnung verbunden. Dies erleichtert die Montage.Preferably, the pad is connected to the clamp cover assembly. This facilitates the assembly.

In einer alternativen Ausgestaltung kann vorgesehen sein, dass die Unterlage als von der Klemmdeckelanordnung getrenntes Bauelement ausgebildet ist. In diesem Fall ist das Auswechseln der Unterlage einfach.In an alternative embodiment it can be provided that the pad is designed as a separate from the clamping cover assembly component. In this case, changing the pad is easy.

Die Aufgabe wird bei einem Verfahren der eingangsgenannten Art dadurch gelöst, dass man die Deckelnuten in einer Unterlage vorsieht, die zwischen der Klemmdeckelanordnung und den Wirkwerkzeugen angeordnet ist, und man die Deckelnuten vor Ort erzeugt, indem man die Wirkwerkzeuge mit einem Material mit Verfestigungsmechanismus abdeckt und das Material auf die Wirkwerkzeuge drückt, so dass das Material auch an die Flanken der Wirkwerkzeuge gelangt, und das Material dann verfestigen lässt.The object is achieved in a method of the type mentioned above by providing the lid grooves in a pad which is arranged between the clamping lid assembly and the knitting tools, and the lid grooves produced on site by covering the knitting tools with a material with hardening mechanism and presses the material on the knitting tools, so that the material also reaches the edges of the knitting tools, and then solidify the material.

Wie oben erläutert, werden die Wirkwerkzeuge dann über ihre Höhe an zwei Bereichen abgestützt, so dass ihre Abstützung stabiler ist als mit einer Abstützung in nur einem Bereich, der beispielsweise von der Rückseite ausgeht.As explained above, the knitting tools are then supported over their height at two areas, so that their support is more stable than with a support in only one area, for example, starting from the back.

Man muss also die Klemmdeckelanordnung selbst nicht verändern.So you do not have to change the clamping lid assembly itself.

Man presst also die Unterlage auf die Wirkwerkzeuge, so dass das Material der Unterlage in einen Bereich zwischen den Wirkwerkzeugen vordringen kann und die Wirkwerkzeuge im Bereich der Vorderseite auch an den Flanken umschließt.So you press the pad on the knitting tools, so that the material of the pad can penetrate into an area between the knitting tools and the knitting tools in the area of the front also encloses the flanks.

Dies ist eine einfache Möglichkeit, die Deckelnuten vor Ort zu Erzeugen. Die Deckelnuten sind dann sehr genau an die Form eines jeden einzelnen Wirkwerkzeugs angepasst.This is an easy way to generate the lid grooves on site. The lid grooves are then adapted very precisely to the shape of each individual knitting tool.

Man verwendet eine Unterlage aus verformbarem Material mit Verfestigungsmechanismus. Die Unterlage kann dann gegebenenfalls nach Austauschen einer größeren Anzahl von Wirkwerkzeugen entsorgt werden und bildet damit ein Wegwerfteil.A base of deformable material with hardening mechanism is used. The pad can then be disposed of optionally after replacing a larger number of knitting tools and thus forms a disposable part.

Die Erfindung wird im Folgenden anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung beschrieben. Hierin zeigt die

einzige Figur
eine stark schematisierte Schnittansicht einer Wirkwerkzeugbarre.
The invention will be described below with reference to a preferred embodiment in conjunction with the drawings. Herein shows the
only figure
a highly schematic sectional view of a knitting tool bar.

Eine Wirkwerkzeugbarre 1 weist einen Korpus 2 auf, der eine Wirkwerkzeugaufnahme 3 trägt. In der Wirkwerkzeugaufnahme 3 sind eine Reihe von Aufnahmenuten 4 vorgesehen. In jeder Aufnahmenut ist ein Wirkwerkzeug 5 angeordnet. Bei dem Wirkwerkezug 5 kann es sich beispielsweise um eine Wirknadel oder Arbeitsnadel handeln.A knitting tool bar 1 has a body 2 which carries a knitting tool holder 3. In the knitting tool holder 3, a number of grooves 4 are provided. In each receiving groove a knitting tool 5 is arranged. The knitting machine train 5 may be, for example, a knitting needle or a working needle.

Jedes Wirkwerkzeug 5 weist eine Rückseite 6, die einem Nutgrund 7 benachbart ist, eine Vorderseite 8 und zwei Flanken 9, 10 auf, wobei die Flanken 9, 10 die Vorderseite 8 und die Rückseite 6 miteinander verbinden.Each knitting tool 5 has a rear side 6 which is adjacent to a groove base 7, a front side 8 and two flanks 9, 10, wherein the flanks 9, 10 connect the front side 8 and the back side 6 to one another.

Die Wirkwerkzeugaufnahme 3 kann beispielsweise aus einem Kunststoff gebildet sein.The knitting tool holder 3 may for example be formed from a plastic.

Die Wirkwerkzeuge 5 werden durch eine Klemmdeckelanordnung 11 in den Aufnahmenuten 4 gesichert. In nicht näher dargestellter Weise kann die Klemmdeckelanordnung 11 dabei mehrere Abschnitte aufweisen, die mit dem Korpus 2 verschraubt sind.The knitting tools 5 are secured by a clamping cover assembly 11 in the grooves 4. In a manner not shown, the clamping lid assembly 11 may have several sections which are bolted to the body 2.

Zwischen der Klemmdeckelanordnung 11 und den Wirkwerkzeugen 5 ist eine Unterlage 12 vorgesehen. In der Unterlage 12 ist für jedes Wirkwerkzeug 5 eine Deckelnut 13 vorgesehen, in die das jeweilige Wirkwerkzeug 5 mit seiner Vorderseite 8 hinein ragt.Between the clamping cover assembly 11 and the knitting tools 5 a pad 12 is provided. In the pad 12, a lid groove 13 is provided for each knitting tool 5, in which the respective knitting tool 5 protrudes with its front side 8 in.

Die Unterlage 12 hat hierbei eine Beschichtung oder besteht aus einem Material, dass erst während oder nach der Montage der Klemmdeckelanordnung 11 seine feste Form erhält. Bei der Montage der Klemmdeckelanordnung werden durch die Klemmdeckelanordnung Bereiche 14 der Unterlage in Zwischenräume 15 zwischen den Wirkwerkzeugen 5 gedrückt und bedecken dabei ausgehend von der Vorderseite 8 die Flanken 9, 10. Wenn das entsprechende Material der Unterlage 12 verfestigt oder ausgehärtet ist, dann hat die Unterlage 12 eine ideale Formanpassung an die Wirkwerkzeuge 5 erreicht und kann die Wirkwerkzeuge 5 damit auch formschlüssig stützen.The pad 12 in this case has a coating or consists of a material that receives its solid form only during or after the assembly of the clamping lid assembly 11. When mounting the clamping cover assembly areas 14 of the pad are pressed into spaces 15 between the knitting tools 5 by the clamping cover assembly and cover it starting from the front side 8, the flanks 9, 10. If the corresponding material of the pad 12 is solidified or cured, then Pad 12 an ideal shape adaptation to the Knitting tools 5 reached and can support the knitting tools 5 so that form fit.

Nach dem Lösen der Klemmdeckelanordnung 11 kann es vorkommen, dass die Unterlage 12 nicht mehr 100 % auf die Wirkwerkzeuge 5 passt. In diesem Fall muss sie bei einer Wiedermontage erneuert werden. Wenn lediglich einzelne Wirkwerkzeuge 5 ausgewechselt werden, ist dies in der Regel nicht erforderlich.After loosening the clamping lid assembly 11, it may happen that the pad 12 no longer 100% fits on the knitting tools 5. In this case, it must be renewed in a reassembly. If only individual knitting tools 5 are replaced, this is usually not required.

Die Unterlage 12 kann entweder mit der Klemmdeckelanordnung 11 verbunden sein oder sie kann als getrenntes Bauelement ausgebildet sein.The pad 12 may either be connected to the clamp cover assembly 11 or it may be formed as a separate component.

Das Material mit Verfestigungsmechanismus der Unterlage kann zum Beispiel chemisch härten, z. B. kationisch härtende Epoxidharze. Man kann bei einem entsprechenden Material auch eine Klebstoffverfestigung durch Druck erreichen oder man kann eine Schutzfolie abziehen und eine Polyreaktion auslösen. Man kann auch ein Zweikomponentenmaterial verwenden, das erst kurz vor der Montage der Klemmdeckelanordnung an den Wirkwerkzeugen auf die Klemmdeckelanordnung oder die Wirkwerkzeuge aufgebracht wird. Der Verfestigungsmechanismus des Materials schließt sowohl eine chemische Härtung als auch ein physikalisches Abbinden mit ein. Die Verfestigung kann sich auch aus dem Entweichen eines Lösemittels oder dem Erstarren einer Schmelze ergeben.The material with solidification mechanism of the pad can, for example, chemically cure, for. B. cationic curing epoxy resins. You can also achieve a Klebverfestigung by pressure with an appropriate material or you can peel off a protective film and trigger a polyreaction. It is also possible to use a two-component material which is applied to the clamping lid arrangement or the knitting tools only shortly before the assembly of the clamping lid arrangement on the knitting tools. The solidification mechanism of the material includes both chemical hardening and physical setting. The solidification can also result from the escape of a solvent or the solidification of a melt.

Da die Wirkwerkzeuge 5 nun über ihre Höhe an zwei Bereichen abgestützt sind, kann man die Höhe einer jeden Abstützung unter Umständen etwas verringern, also die Aufnahmenuten 3 und die Deckelnuten 13 etwas flacher ausbilden. Durch die hiermit verbundene Materialeinsparung ergibt sich auch eine geringere Masse, was sich wiederrum positiv auf das Betriebsverhalten der Kettenwirkmaschine auswirkt.Since the knitting tools 5 are now supported over their height at two areas, you can reduce the height of each support under certain circumstances something, so form the grooves 3 and the lid grooves 13 slightly flatter. Due to the associated savings in material also results in a lower mass, which in turn has a positive effect on the performance of the warp knitting machine.
