Description

Modul mit Tuftingwerkzeusen  Module with tufting tools
Beschreibung description
Die Erfindung betrifft ein Modul mit Tuftingwerkzeugen, insbesondere Nadeln, bei dem die Tuftingwerkzeuge in einen Grundkörper eingegossen sind, dessen Länge einem Vielfachen des Mittenabstandes der eingegossenen Tuftingwerkzeuge entspricht, der auf seiner an eine Barre anschließbaren Rückseite mit einer Anlägeleiste und Ausnehmungen sowie auf seiner Vorderseite mit einer Aufnahmeschulter und Vorsprüngen versehen ist und der ein in Längsrichtung des Moduls verlaufendes, von der Rückseite zur Vorderseite durchgehendes Langloch hat. Ein derartiges Modul für eine Tuftingmaschine ist aus DE-PS 2 828 278 bekannt. Dabei sind die Module an eine Nadelbarre anschraubbar. Jeder Grundkörper hat auf seiner der Nadeibarre zugewandten Rückseite zwei konische, in Längsrichtung des Moduls auf Abstand angeordnete Ausnehmungen. Entsprechend sind auf der Vorderseite des Grundkcrpers zwei ebenfalis auf Abstand stehende Vorsprünge vorgesehen. Die Ausnenmungen und die Vorsprünge sind so aimensiomert, daß die Vorsprünge des einen Moduls in die Ausnehmungen eines anderen eingreifen Können, wenn die beiden so aneinandergefugten Module um eine nalbe Nadelteiiung gegeneinander versetzt sind. The invention relates to a module with tufting tools, in particular needles, in which the tufting tools are cast into a base body, the length of which corresponds to a multiple of the center distance of the cast-in tufting tools, which has a contact bar and recesses on its rear side, which can be connected to a bar, and on its front side is provided with a receiving shoulder and projections and has an elongated hole running in the longitudinal direction of the module and going from the back to the front. Such a module for a tufting machine is known from DE-PS 2 828 278. The modules can be screwed onto a needle bar. Each base body has on its rear side facing the needle bar two conical recesses which are spaced apart in the longitudinal direction of the module. Correspondingly, two projections which are also spaced apart are provided on the front of the base body. The Ausnenmungen and the projections are so aimed that the projections of one module can engage in the recesses of another, if the two modules joined together are offset by a half needle assembly.
Mit dem bekannten Modul ist es also möglich, zwei Nadeireihen durch Bildung von zwei entsprechenden Modulreinen zu scnaffen, wobei dann die Nadeln der einen Reine zu denen der anderen um eine halbe Teilung versetzt sind. With the known module it is therefore possible to create two rows of needles by forming two corresponding module rows, in which case the needles of one row are offset by half a division from those of the other.
Beim Tuften wird mit einer großen Anzahl aoweicnenαer Teilungen der Tfftingwerkzeuge gearbeitet. Dies führt bei dem bekannten Modul dazu, daß für jede Teilung gesondert ein Grundkörper hergestellt werden muß, bei dem die Vorsprünge der Vorderseite relativ zu den Ausnehmungen der Rückseite entsprechend der jeweils gewünschten Teilung versetzt anzuordnen sind. When tufting, a large number of separate divisions of the tufting tools are used. This leads to the Known module that a base body must be made separately for each division, in which the projections of the front are to be arranged offset relative to the recesses on the back according to the desired division.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, diesen Nachteil des bekannten Moduls zu vermeiden. Es soll insbesondere erreicht werden, ohne Einbuße an Präzision der aneinanderzufügenden Module die Zahl der erforderlichen unterschiedlich zu gestaltenden Grundkörper zu reduzieren. The object of the present invention is now to avoid this disadvantage of the known module. In particular, the aim is to reduce the number of required differently designed basic bodies without sacrificing the precision of the modules to be joined together.
Diese Aufgabe wird bei einem Modul der eingangs erwähnten Art erfindungsgemäß dadurch gelöst, daß die Vertiefungen auf der Rückseite durch die Zwischenräume einer versenkt angeordneten Zahnreihe gebildet sind, deren Zähne untereinander gleich und äquidistant angeordnet sind und gerade Zahnflanken haben, daß die Vorsprünge auf üer Vorderseite durch eine vorstenende Zahnleiste gebildet sind, wobei die Zänne und die Zwischenräume der Zahnleiste den Zwiscnenräu- men bzw. den Zähnen der Zahnreihe angepaßt sind. This object is achieved according to the invention in a module of the type mentioned at the outset in that the depressions on the back are formed by the interspaces of a recessed row of teeth, the teeth of which are arranged identically and equidistantly from one another and have straight tooth flanks, in that the projections on the front side a protruding toothed rack is formed, the teeth and the spaces between the toothed rack being matched to the intermediate spaces or the teeth of the row of teeth.
Die versenkt angeordnete Zahnreihe läßt ein problemloses Ansegen der Rückseite des Moduls an eine Barre, z.B. Nadelbarre, zu . Die Zähne der Zahnleiste auf der Vorderseite eines Moduls können leicht in die Zwischenräume der Zahnreihe eines anderen Moduls eingeführt werden. Es kommt dabei zu einem seibsttätigen Ausrichten in Längsrichtung. Es ist dabei möglich, die Verbindung zwischen zwei derart meinan- αergreifenden Modulen um einen weiteren oder um mehrere weitere Zähne zu versetzen. Dadurch läßt sich folglich die Reiativstellung der Tuftingwerkzeuge benachbarter Reihen zwei-oder mehrstufig verändern. Das erfindungsgemäße Modul kann ferner so ausgebildet sein, daß der Mittenabstand der Tuftingwerkzeuge das n-fache des Aostandes zwischen den Zahnen ausmacht, wobei n eine ganze Das erfindungsgemäße Modul kann ferner so ausgebildet sein, daß die Zwischenräume der Zahnreihe gegenüber den Zähnen der Zahnleiste versetzt sind, wobei dieser Versatz 1/n des Mittenabstandes zwischen den Tuftingwerkzeugen und n eine ganze Zahl > 1 ist. The recessed row of teeth allows the back of the module to be easily drawn onto a bar, eg a needle bar. The teeth of the rack on the front of one module can be easily inserted into the spaces between the teeth of another module. This leads to self-aligning in the longitudinal direction. It is possible to offset the connection between two modules engaging in this manner by one or more teeth. As a result, the position of the tufting tools in adjacent rows can be changed in two or more stages. The module according to the invention can also be designed so that the center distance of the tufting tools is n times the aostasis between the teeth, n being a whole The module according to the invention can also be designed so that the spaces between the row of teeth are offset from the teeth of the toothed rack, this offset 1 / n of the center distance between the tufting tools and n being an integer> 1.
Das erf indungegemäße Modul kann ferner so ausgebildet sein, daß die Teilung der Zahnleiste und der Zahnreihe 5/64, 1/20 oder 1/16 Zoll beträgt. The module according to the invention can also be designed such that the pitch of the toothed rack and the tooth row is 5/64, 1/20 or 1/16 inch.
So ist es z.B. möglich, die Zahnreihe und die Zahnleiste des Grundkörpers mit einer Teilung von 5/64-Zoll auszubilden. Die für diesen Grundkörper erforderliche Form kann dann ohne jegliche Veränderungen dazu verwendet werden, Tuftingwerkzeuge mit einer 5/64- oder 5/32- oder 5/16-Teilung aufzunehmen. Beim Eingießen der Tuftingwerkzeuge sind diese lediglich entsprechend der vorgeschriebenen Teilung in der Form des Grundkörpers zu plazieren. Dadurch wird eine starke Reduktion der erforderlichen Formen zur Herstellung der Grundkörper erreicht. So it is e.g. possible to form the row of teeth and the toothed rack of the base body with a pitch of 5/64-inch. The shape required for this base body can then be used without any changes to accommodate tufting tools with a 5/64 or 5/32 or 5/16 pitch. When pouring the tufting tools, they are only to be placed according to the prescribed division in the shape of the base body. As a result, the required shapes for producing the base body are greatly reduced.
Das erfindungsgemäße Modul kann ferner so ausgebildet sein, daß die Zahnreihe der Anlageleiste und die Zahnleiste αer Aufnahmeschulter benachbart ist. The module according to the invention can also be designed such that the row of teeth of the contact strip and the toothed strip are adjacent to the receiving shoulder.
Die Anlageleiste und die Aufnahmeschul ter dienen dazu, das Ausrichten der Module an der Barre bzw. an der benachbarten Modulreihe zu vereinfachen. Schließlich kann das erfindungsgemäße Modul so ausgebildet sein, daß die Zahnflanken jedes Zahnes miteinander einen Winkel von 35 bis 50 bilden. Versuche haben gezeigt, daß sich insbesondere in diesem Winkelbereich der Zähne ein optimales Ineinandergreifen und damit Ausrichten ergibt, wobei die auftretende Druckkraft von der Flanke des einen Zahns auf die des benachbarten Zahns übertragen wird. Das Entformen wird dabei ohne Schwierigkeiten möglich. Im folgenden Teil der Beschreibung wird eine Ausführungs- form des erfindungsgemäßen Moduls in Verbindung mit Nadeln als Tuftingwerkzeuge beschrieben. Es zeigt: Fig. 1: eine Ansicht der Vorderseite eines erfindungsgemäß ausgebildeten Moduls, The system bar and the mounting shoulder serve to simplify the alignment of the modules on the bar or on the adjacent row of modules. Finally, the module according to the invention can be designed such that the tooth flanks of each tooth form an angle of 35 to 50 with one another. Experiments have shown that, particularly in this angular range of the teeth, there is an optimal interlocking and thus alignment, the compressive force occurring being transmitted from the flank of one tooth to that of the adjacent tooth. De-molding is possible without difficulty. In the following part of the description, an embodiment of the module according to the invention is described in connection with needles as tufting tools. 1 shows a view of the front of a module designed according to the invention,

Das in den Figuren dargestellte Modul hat einen Grundkörper 1, in den die Kolben von parallel und äquidistant angeordneten Tufti ngnadeln 2 eingegossen sind. Der Grundkörper 1 hat eine Rückseite 3 und eine parallel dazu veriaufende Vorderseite 4. Rückseite 3 und Vorderseite 4 laufen parallel zueinander. Von der Rückseite 2 springt eine Anlageleiste 5 vor. Dieser Aniageleiste 5 ist eine in der Ruckseite 3 versenkt angeordnete Zahnreihe 6 benachbart. The module shown in the figures has a base body 1, into which the pistons of tufting needles 2 arranged in parallel and equidistantly are cast. The base body 1 has a rear side 3 and a front side 4 running parallel thereto. The rear side 3 and front side 4 run parallel to one another. From the rear 2, a system bar 5 projects. This angling bar 5 is adjacent to a row of teeth 6 sunk in the rear side 3.
Auf der Vorderseite 4 ist auf der Höhe der Anlageleiste 5 eine Aufnahmeschulter 7 vorgesehen. Dieser ist eine aus der Vorderseite 4 vorstehende Zahnleiste 8 benachbart. A receiving shoulder 7 is provided on the front 4 at the level of the contact bar 5. This is one from the Front 4 protruding rack 8 adjacent.
Im Grundkorper ist ferner ein Langloch 9 vorgesehen, das αurch den Grundkorper 1 hindurchreicht und dessen längere Achse in Längsrichtung des Moduls weist. Der Durchmesser des Langlochs 9 erweitert sich aus entformungstechm sehen Gründen von der Vorderseite 4 in Richtung auf die Ruckseite 3. Die versenkt angeordnete Zahnreihe 6 hat aquidistant angeordnet Zahne 10 mit geraden Flanken. Das Profil der Zahne 10 entspricht dem Profil der Zwischenräume 11 zwischen den Zahnen 10. Die Zahnleiste 6 auf der Vorderseite 4 hat Zahne 12 und Zwischenräume 13, die in ihrem Profil demjenigen der Zahnreihe 6 entsprechen. Im dargestellten Ausfuhrungsoeispiel liegt jeweils ein Zahn 12 der Zahnleiste 8 gegenüber einem Zwiscnenraum 11 der Zahnreihe 6. Die Zahne 12 der Zahnleiste 8 können folglich in die Zwischenräume 11 der Zahnreihe b eines weiteren, gleich ausgebildeten Moduls eingeführt werden, wobei die Vorderseite 4 dann auf der Rückseite 3 zu liegen kommt. Zwei derart aneinandergefügte Module können in mehreren, in, Längsrichtung des Moduls gegeneinander verschopenen Stellungen derart aneinandergefügt werden. An elongated hole 9 is also provided in the base body, which extends through the base body 1 and has its longer axis in the longitudinal direction of the module. The diameter of the elongated hole 9 widens from the front 4 in the direction of the back 3 for demolding reasons. The recessed row of teeth 6 has aquidistant teeth 10 with straight flanks. The profile of the tooth 10 corresponds to the profile of the spaces 11 between the teeth 10. The toothed strip 6 on the front 4 has teeth 12 and spaces 13 which correspond in their profile to that of the row of teeth 6. In the exemplary embodiment shown, each tooth 12 of the toothed rack 8 lies opposite an intermediate space 11 of the tooth row 6. The teeth 12 of the toothed rack 8 can consequently be inserted into the spaces 11 of the tooth row b of a further module of the same design, the front side 4 then on the Back 3 comes to rest. Two modules joined together in this way can be joined together in a plurality of positions which are mutually locked in the longitudinal direction of the module.
Die Figuren 5 - 8 zeigen zwei derart aneinandergefügte Module. In dieser Position liegt jeweils die Anlageieiste 5 des einen Moduls auf der Autnahmeschulter 7 des anderen Moduls, wahrend die Zahnleiste 8 des einen in die Zahnreine 6 des anderer, eingreift. Wenn die so aneinandergesetzten Module relativ zueinander in Langsrichtung der Moduie versetzt sind, dann fluchten die Langlocher 9 nicht volistan- dig miteinander, sondern jedes Langloch überragt das jeweiis andere in Längsrichtung. Beide Langiocher der aufei nandergesetzten Module lassen aber einen gemeinsamen Durchlaß frei, durch den eine nicht dargestellte Schraube zum Festlegen der Module an der Barre hindurchgefuhrt werden kann. Das Modul kann zur Bildung einer Nadelreihe, durch Aneinandersetzen von zwei Modulreihen zur Bildung von zwei Nadelrei hen sowi e auch zur Bi l dung von drei oder vi er Nadel reihen verwendet werden. Lediglich die Länge der Langlöcher 9 ist entsprechend dem maximalen Versatz der beiden aufeinanderliegenden Module zu wählen. Figures 5-8 show two modules joined together in this way. In this position, the contact strip 5 of the one module lies on the shoulder 7 of the other module, while the toothed strip 8 of the one engages in the toothed portion 6 of the other. If the modules placed in this way are offset relative to one another in the longitudinal direction of the module, then the elongated holes 9 are not flush with one another, but each elongated hole projects above the other in the longitudinal direction. Both Langiocher the aufei nanderges modules leave a common passage through which a screw, not shown, can be passed to fix the modules on the bar. The module can be used to form a row of needles, by putting two rows of modules together to form two rows of needles, and also to form three or more rows of needles. Only the length of the elongated holes 9 is to be selected in accordance with the maximum offset of the two modules lying one on top of the other.
