Abstract
Description
Die Erfindung betrifft ein Lochnadelsegment zum Einsatz an Häkel- oder Raschelmaschinen mit den Einzelmerkmalen des Oberbegriffes des Anspruches l. Derartige Lochnadelsegmente bestehen im wesentlichen aus einem mit einem bewegungsangetriebenen Teil der Maschine verbundenen Trägerkörper sowie einer Mehrzahl von Lochnadellamellen, die aus einer Seitenfläche, nämlich aus einer Stirnfläche des Trägerkörpers parallel und äquidistant herausstehen.The invention relates to a perforated needle segment for use on crochet or Raschel machines with the individual features of the preamble of claim l. Such perforated needle segments essentially consist of a carrier body connected to a movement-driven part of the machine and a plurality of perforated needle lamellae which protrude parallel and equidistantly from a side face, namely from an end face of the carrier body.
Die Lochnadeln sind an ihrem Freiende mit einem Loch zur Durchführung eines u. U. elastischen Fadenabschnittes versehen, mit ihrem Befestigungsende sind die Lochnadeln im Trägerkörper gehalten.The perforated needles are at their free ends with a hole for performing a u. U. elastic thread section provided, with its fastening end, the needles are held in the carrier body.
Da beim Betrieb der mit den Lochnadelsegmenten versehenen Häkel- oder Raschelmaschine die Segmente an einem Querträger befestigt sind, der eine elliptische Rotationsbewegung mit einer relativ hohen Umlauffrequenz ausführt, wirken nicht unerhebliche mechanische Kräfte auf die Verbindung zwischen Lochnadeln und Trägerkörper ein.Since during the operation of the crochet or Raschel machine provided with the perforated needle segments, the segments are attached to a cross member, which has an elliptical rotational movement with a relatively high rotational frequency executes, not inconsiderable mechanical forces act on the connection between perforated needles and carrier body.
Als Stand der Technik ist es bekannt, einen Trägerkörper aus Metall, insbesondere Blei herzustellen, die Lochnadeln in ihrem Befestigungsende in Schlitzausnehmungen des aus Blei hergestellten Trägerkörpers einzulegen und darin zu befestigten. Derartige Lochnadelsegmente, jedoch insofern nachteilig, als sie nur mehr oder weniger in einem Handgußverfahren hergestellt werden können und aufgrund des bleiernen Trägerkörpers eine relativ große Masse haben, die aufgrund des Rotationsantriebes der Trägerkörper nur relativ geringfügige Maschinentourenzahlen erlaubt.It is known as prior art to produce a carrier body made of metal, in particular lead, to insert the perforated needles in their fastening end into slot recesses in the carrier body made of lead and to fasten them therein. Such perforated needle segments, however, disadvantageous in that they can only be produced to a greater or lesser extent in a hand casting process and have a relatively large mass due to the leaded carrier body, which allows only relatively small numbers of machine tours due to the rotational drive of the carrier body.
Es wurde auch schon versucht, die Lochnadellamellen in Trägerkörper aus Kunststoff einzugießen, derartige Lochnadelsegmente konnten sich aber nicht durchsetzen, da der Halt der Einzelnadeln nicht ausreichend in dem Kunststoffkörper gesichert war, um die relativ hohen mechanischen Belastungen dauerhaft zu ertragen. Wenn sich nur eine einzige Lochnadel aus einem Trägerkörper löst, führt dies zum sofortigen Ausfall der Häkel- oder Raschelmaschine, an der in der Regel viele Segmente angeordnet sind. Um übermäßig hohe Ausfallzeiten durch ein Herausfallen von Lochnadeln zu vermeiden, ist man wieder dazu übergegangen, vorstehend erläuterte Lochnadelsegmente mit einem Trägerkörper aus Blei und einzeln darin befestigten Lochnadellamellen zu verwenden.Attempts have also already been made to pour the perforated needle lamellae into carrier bodies made of plastic, but such perforated needle segments could not prevail because the hold of the individual needles was not sufficiently secured in the plastic body in order to sustain the relatively high mechanical loads. If only a single perforated needle comes loose from a carrier body, this leads to the immediate failure of the crochet or Raschel machine, on which many segments are usually arranged. In order to avoid excessively long downtimes due to dropping out of perforated needles, it has again become common to use the above-explained perforated needle segments with a lead body and individually attached perforated needle lamellae.
Der Erfindung/Neuerung liegt die Aufgabe zugrunde, ein Lochnadelsegment der vorstehend bezeichneten Art derart weiterzubilden, daß es gewichtsmäßig reduziert und dabei ein dauerhaft fester Verbund zwischen Trägerkörper und Lochnadellamellen sichergestellt ist. Die Segmente sollen dabei auch leicht herstellbar und durch Einsparung von metallischen Rohstoffen preisgünstig sein.The invention / innovation is based on the object of developing a perforated needle segment of the type described above in such a way that it reduces weight and at the same time a permanently firm bond between the carrier body and the perforated needle lamella is ensured. The segments should also be easy to manufacture and inexpensive by saving on metallic raw materials.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches l gelöst, vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Merkmalen der Unteransprüche.This object is achieved by the characterizing features of claim 1, advantageous developments of the invention result from the features of the subclaims.
Als Kern der Erfindung/Neuerung wird es angesehen, im Bereich der Befestigungsenden der Lochnadellamellen mindestens einen stabförmigen Querverbinder anzuordnen, der mit den Festenden der Einzellamellen fest verbunden ist und innerhalb des Trägerkörpers über die gesamte Breite der Lochnadelanordnung im wesentlichen rechwinklig zur Nadellängsrichtung verläuft. Durch diesen Querverbinder wird ein fester Halt der Nadeln untereinander erreicht und gleichzeitig sichergestellt, daß durch die Querstrebe im Trägerkörpermaterial der gesamte Lochnadelverbund sich nicht aus dem Trägerkörper lösen kann. Steht der stabartige Querverbinder noch über den Seitenrand der Lochnadelfestenden erhaben hinaus, wird gleichsam eine formschlüssige Verbindung mit dem Trägerkörpermaterial hergestellt und der Halt noch weiter erhöht. Besonders vorteilhaft ist es, wenn gemäß Anspruch 3 der Trägerkörper aus Kunststoffmaterial, insbesondere ABS-Kunststoff besteht, da sich dann der vorbereitete und mit dem Querverbinder versehene Lochnadelsatz auf einfache Weise in den Kunststoffkörper einspritzen oder eingießen läßt.As the core of the invention / innovation, it is considered to arrange at least one rod-shaped cross connector in the area of the fastening ends of the perforated needle lamellae, which is firmly connected to the fixed ends of the individual lamellae and runs within the carrier body over the entire width of the perforated needle arrangement essentially at right angles to the longitudinal direction of the needle. This cross connector ensures a firm hold of the needles with one another and at the same time ensures that the entire perforated needle assembly cannot become detached from the support body through the cross strut in the support body material. If the rod-like cross connector is still raised beyond the side edge of the perforated needle fixed ends, a positive connection is established with the carrier body material and the hold is increased even further. It is particularly advantageous if, according to
Durch mehrere Querverbinder beidseitig im Bereich des Befestigungsendes der Lochnadellamellen wird sichergestellt, daß das zum Einspritzen vorbereitete Lochnadelpaket sich nicht verwindet oder verbiegt, was zur Folge hat, daß die einzelnen Lochnadeln ihre Äquidistanz zueinander verlieren.A plurality of cross-connectors on both sides in the area of the fastening end of the perforated needle lamellae ensures that the perforated needle package prepared for injection does not twist or bend, with the result that the individual perforated needles lose their equidistance to one another.
Vorteilhafterweise bestehen der oder die Querverbinder aus Schweißdraht und werden durch ein Elektroschweißverfahren auf dem Rücken der Nadellamellen befestigt. Der Schweißdraht wirkt sich auch insofern vorteilhaft aus, als er eine gewisse Biegsamkeit hat, die es gestattet, den vorbereiteten Lochnadelverbund nach dem Einlegen in entsprechende Aussparungen der Spritzform zur Herstellung des Trägerkörpers noch nachzurichten und damit sicherzustellen, daß die Lochnadelausrichtung wirklich exakt ist. Als statisch besonders vorteilhaft hat sich eine Dreieranordnung des Querverbinders herausgestellt.The cross connector (s) advantageously consist of welding wire and are attached to the back of the needle lamellae by means of an electric welding process. The welding wire also has an advantageous effect in that it has a certain flexibility, which allows the prepared perforated needle assembly to be re-aligned after insertion into corresponding recesses in the injection mold for the production of the carrier body and thus to ensure that the perforated needle alignment is really exact. A tripartite arrangement of the cross connector has proven to be particularly advantageous statically.
Eine wirklich innige Verbindung zwischen Querverbinder und Lochnadellamellen läßt sich dadurch erreichen, daß die Rücken oder Seitenkanten der Lochnadellamellen mit U-förmigen Ausnehmungen versehen sind, in die der als Schweißdraht ausgebildete Querverbinder eingelegt wird. Der Radius der U-förmigen Ausnehmungen entspricht etwa dem Radius des Schweißdrahtes, so daß sich eine relativ lange Schweißverbindung ergibt.A really intimate connection between cross connector and perforated needle lamellae can be achieved by providing the back or side edges of the perforated needle lamellae with U-shaped recesses into which the cross connector designed as a welding wire is inserted. The radius of the U-shaped recesses corresponds approximately to the radius of the welding wire, so that there is a relatively long welded connection.
Für eine einwandfreie Funktion der Lochnadelsegmente ist es erforderlich, daß auch nach dem Herstellungsvorgang alle Nadeln exakt parallel verlaufen. Da der erkaltende Kunststoff nach dem Spritzvorgang eine Schrumpfung von etwa 0,8 % - l % vollzieht, neigen die kammartig angeordneten Lochnadeln dazu, sich fächerförmig aufzubiegen, d. h. im Bereich ihrer Nadelspitzen einen etwas größeren Abstand einzunehmen als im Bereich der Lochnadelenden. Eine derartige Aufweitung durch Kontraktion des Kunststoffes wird dadurch vermieden, daß man die Spannung im Bereich des Kunststoffrückens durch Ausnehmungen reduziert, die vorteilhafterweise eine Mehrzahl von Ausnehmungen sind, die sich zwischen dem Befestigungsloch und den Lochnadeln parallel zueinander in Nadellängsrichtung erstrecken. Die Ausnehmungen haben die Form von Langlöchern.For perfect functioning of the perforated needle segments, it is necessary that all needles run exactly parallel even after the manufacturing process. Since the cooling plastic shrinks by about 0.8% - 1% after the injection process, the comb-like needles tend to bend open like a fan, ie to take a slightly greater distance in the area of their needle tips than in the area of the needle ends. Such expansion by contraction of the plastic is avoided by reducing the tension in the area of the plastic back through recesses, which are advantageously a plurality of recesses that extend parallel to one another in the longitudinal direction of the needle between the fastening hole and the perforated needles. The recesses have the shape of elongated holes.
Eine weitere Versteifung der Trägerkörper wird dadurch erreicht, daß eine Mehrzahl von Versteifungsrippen vorgesehen ist, die insbesondere den Trägerkörperrand einfassen und in der Trägerkörpermitte zumindest teilweise in Nadellängsrichtung verlaufen.A further stiffening of the carrier body is achieved in that a plurality of stiffening ribs are provided, which in particular enclose the edge of the carrier body and at least partially run in the center of the carrier body in the longitudinal direction of the needle.
Im Bereich des Befestigungsloches ist ebenfalls eine Verstärkung des Trägerkörpers vorgesehen, die in die Versteifungsrippen übergeht. Dadurch wird vermieden, daß der Trägerkörper bei hoher Belastung im Bereich des Befestigungsloches ausbricht.In the area of the fastening hole, a reinforcement of the support body is also provided, which merges into the stiffening ribs. This prevents the carrier body from breaking out in the area of the fastening hole under high loads.
Die Verfahrensansprüche stellen eine rationelle und billige Herstellung des Anmeldungsgegenstandes sicher.The procedural claims ensure rational and cheap manufacture of the subject of the application.
