Description

Die Erfindung betrifft ein Platinenschloss für Rundstrickmaschinen, insbesondere für Single-Jersey-Maschinen, mit mindestens einem an einem Schlossträger angeordneten Schlossteil zur Steuerung von Austriebs- und Rückzugsbewegungen von Platinen, wobei das Schlossteil bezüglich des Schlossträgers in Bewegungsrichtung der Platinen verstellbar ist.The invention relates to a sinker lock for circular knitting machines, in particular for single jersey machines, with at least one lock part arranged on a lock carrier for controlling the expulsion and retraction movements of sinkers, the lock part being adjustable with respect to the lock carrier in the direction of movement of the sinkers.

Es sind Platinenschlösser bekannt und vielfach im Einsatz, bei denen die Platinenschlossteile fest auf dem Schlossträger montiert sind. Diese Schlösser eignen sich jedoch nicht für Maschinen hoher Feinheit ab E44, da die Schlossteile nicht verstellbar sind, bei hohen Feinheiten eine Verstellung der Schlossteile zum Ausgleich von Fertigungstoleranzen jedoch erforderlich ist.There are sinker locks known and often in use in which the sinker lock parts are firmly mounted on the lock carrier. However, these locks are not suitable for machines of high fineness from E44, since the lock parts are not adjustable, but with high fineness an adjustment of the lock parts is necessary to compensate for manufacturing tolerances.

Zur Feineinstellung der Position der Platinenschlossteile zum Ausgleich der Fertigungstoleranzen bei Maschinen mit einer sehr feinen Nadelteilung, werden daher bisher in der Regel Platinenschlosssegmente eingesetzt, die fest mit dem Platinenschlossträger verschraubt sind und die ein Verstellteil für das Platinenschlossteil aufweisen. Die Platinenschlossteile sind dabei längsverschieblich an der Unterseite der Platinenschlosssegmente angeordnet.To fine-tune the position of the sinker lock parts to compensate for the manufacturing tolerances on machines with a very fine needle pitch, sinker lock segments that are firmly screwed to the sinker lock carrier and that have an adjustment part for the sinker lock part have therefore been used so far. The sinker lock parts are arranged to be longitudinally displaceable on the underside of the sinker lock segments.

Die Platinenschlosssegmente stehen jedoch relativ weit über den Platinenschlossträger und die Platinenschlossteile über, sodass die Sicht auf die Platinen und die Zylindernadeln der Maschine behindert wird. Außerdem sind die Zylindernadeln nur schwer zugänglich. Ein weiterer Nachteil der bekannten Platinenschlösser liegt darin, dass Fadenflaum nur unzureichend von der Strickstelle abgeblasen werden kann. Der Flaum tendiert dazu, sich in einer Kuhle zwischen der Platine und dem Platinenschlosssegment anzusammeln.The sinker lock segments, however, protrude relatively far beyond the sinker lock carrier and the sinker lock parts, so that the view of the sinkers and the cylinder needles of the machine is obstructed. In addition, the cylinder needles are difficult to access. Another disadvantage of the known sinker locks is that thread fluff can only be insufficiently blown off the knitting point. The fluff tends to collect in a hollow between the sinker and the sinker segment.

Die EP 1 559 820 A1 beschreibt eine Verstelleinrichtung für Schlossteile, wobei die Verstelleinrichtung im Schlossträger angeordnet ist und über ein an der Unterseite des Schlossteils angreifendes separates Verstellelement eine Längsverstellung des Schlossteils erlaubt. Diese Verstelleinrichtung erfordert jedoch speziell gestaltete Schlossträger mit einer Aussparung für die Verstellelemente.the EP 1 559 820 A1 describes an adjustment device for lock parts, the adjustment device being arranged in the lock carrier and allowing a longitudinal adjustment of the lock part via a separate adjustment element engaging the underside of the lock part. However, this adjustment device requires specially designed lock carriers with a recess for the adjustment elements.

Weitere Beispiele von Verstelleinrichtungen für Schlossteile finden sich in den Dokumenten DE 36 34 784 C1 , EP 0 302 286 A1 und EP 0 531 789 A1 .Further examples of adjustment devices for lock parts can be found in the documents DE 36 34 784 C1 , EP 0 302 286 A1 and EP 0 531 789 A1 .

Aufgabe der Erfindung ist es daher, ein Platinenschloss bereitzustellen, das verstellbare Platinenschlossteile aufweist und die oben beschriebenen Nachteile vermeidet.The object of the invention is therefore to provide a sinker lock which has adjustable sinker lock parts and which avoids the disadvantages described above.

Die Aufgabe wird gelöst durch ein Platinenschloss für Rundstrickmaschinen, insbesondere für Single-Jersey-Maschinen, mit mindestens einem an einem Schlossträger angeordneten Schlossteil zur Steuerung von Austriebs- und Rückzugsbewegungen von Platinen, wobei das Schlossteil bezüglich des Schlossträgers in Bewegungsrichtung der Platinen verstellbar ist und das Schlossteil unmittelbar auf dem Schlossträger angeordnet ist und ein in das Schlossteil integriertes Verstellteil vorgesehen ist, mit dem das Schlossteil gegenüber dem Schlossträger verstellbar ist.The object is achieved by a sinker lock for circular knitting machines, in particular for single jersey machines, with at least one lock part arranged on a lock carrier for controlling the expulsion and retraction movements of sinkers, the lock part being adjustable with respect to the lock carrier in the direction of movement of the sinkers and that The lock part is arranged directly on the lock carrier and an adjustment part integrated into the lock part is provided, with which the lock part can be adjusted relative to the lock carrier.

Das erfindungsgemäße Platinenschloss verzichtet auf Platinenschlosssegmente. Stattdessen wird das Schlossteil direkt verschiebbar auf dem Platinenschlossträger angeordnet. Die Bauhöhe des Schlosses ist damit deutlich geringer als bei Platinenschlössern mit Schlosssegmenten. Die Sicht auf die Strickstelle mit den Platinen und Nadeln wird nicht behindert. Außerdem kann die Strickstelle leicht von Fadenflaum gereinigt werden, der sich zudem in geringerem Maße auf den Platinenschlossteilen absetzt als bei bekannten Schlössern. Dabei bleibt die erforderliche Verstellbarkeit der Schlossteile in vollem Umfang erhalten. Das erfindungsgemäße Platinenschloss erlaubt außerdem eine Verstellung der Platinenschlossteile, wenn bestimmte zu strickende Muster dies erfordern. Zur Anpassung an verschiedene Muster kann das Schlossteil zudem auch zweiteilig ausgebildet sein, d.h. einen auswechselbaren Abschnitt aufweisen. Bei einem Musterwechsel müssen dann nicht die gesamten Schlossteile sondern nur die auswechselbaren Abschnitte ausgetauscht werden, wodurch sich eine deutliche Materialersparnis ergibt.The sinker lock according to the invention dispenses with sinker lock segments. Instead, the lock part is arranged so that it can be moved directly on the sinker lock carrier. The overall height of the lock is thus significantly lower than that of plate locks with lock segments. The view of the knitting point with the sinkers and needles is not obstructed. In addition, the knitting point can easily be cleaned of thread fluff, which also settles to a lesser extent on the sinker lock parts than with known locks. The required adjustability of the lock parts is retained in full. The sinker lock according to the invention also allows adjustment of the sinker lock parts if this is required by certain patterns to be knitted. In order to adapt to different patterns, the lock part can also be designed in two parts, ie it can have an exchangeable section. In the case of a pattern change, it is not then necessary to replace all of the lock parts, but rather only the exchangeable sections, which results in a significant saving in material.

Bei einer bevorzugten Ausgestaltung des Schlosses liegt das Schlossteil unter Federvorspannung auf dem Schlossträger auf und ist unter Überwindung der Reibung zwischen der Schlossträgeroberfläche und der Schlossteilunterseite vom Verstellteil gegenüber dem Schlossträger verstellbar. Durch die Federvorspannung wird ein unbeabsichtigtes Verschieben des Schlossteils auf dem Schlossträger vermieden, ohne dabei die Verstellbarkeit des Schlossteils über das Verstellteil zu behindern.In a preferred embodiment of the lock, the lock part rests on the lock carrier under spring tension and can be adjusted by the adjustment part relative to the lock carrier by overcoming the friction between the lock carrier surface and the underside of the lock part. The spring preload prevents unintentional displacement of the lock part on the lock carrier without hindering the adjustability of the lock part via the adjustment part.

Dazu kann das Schlossteil vorzugsweise mittels mindestens einer Schraube mit einer Tellerfeder am Schlossträger befestigt sein, wobei die Schraube durch ein Langloch oder ein Loch größeren Durchmessers als der Schraubenschaft im Schlossteil geführt ist. Das Langloch ermöglicht eine Verschiebebewegung des Schlossteils durch das Verstellteil. Die Schraube kann auch in Verstellrichtung des Schlossteils geneigt in den Schlossträger eingeschraubt sein.For this purpose, the lock part can preferably be fastened to the lock carrier by means of at least one screw with a plate spring, the screw being guided through an elongated hole or a hole with a larger diameter than the screw shaft in the lock part. The elongated hole enables the lock part to be displaced through the adjustment part. The screw can also be screwed into the lock carrier at an angle in the adjustment direction of the lock part.

Der Einbau des Verstellteils in das Schlossteil bietet den Vorteil, dass die Schlossteile bei allen Maschinen, unabhängig von deren Aufbau und Feinheit eingesetzt werden können.The installation of the adjustment part in the lock part offers the advantage that the lock parts can be used in all machines, regardless of their structure and fineness.

Das Verstellteil kann einen drehbaren Stellkopf aufweisen, der mit einem Stift verbunden ist, der in eine Spiralnut im Verstellteil oder im Schlossträger eingreift. Das Verstellteil entspricht damit dem Kulierverstellteil, das schon bei bekannten Schlössern eingesetzt wird. Der Stellkopf kann durch einen Steckschlüssel gedreht werden und dadurch das Platinenschlossteil verschieben. Dabei kann in an sich bekannter Weise eine mit einer Skala versehene Scheibe oder Ring an dem Stellkopf angeordnet sein, um die Einstellung der Schlossteilposition zu erleichtern.The adjustment part can have a rotatable adjusting head which is connected to a pin which engages in a spiral groove in the adjustment part or in the lock carrier. The adjustment part thus corresponds to the cam adjustment part that is already used in known locks. The adjusting head can be turned by a socket wrench and thereby move the sinker lock part. A disk or ring provided with a scale can be arranged on the adjusting head in a manner known per se in order to facilitate the adjustment of the lock part position.

Das Verstellteil kann jedoch auch an einer Stirnseite des Schlossteils angeordnet sein, wobei das Schlossteil über ein Zahnrad, eine Zahnstange oder ein Schneckengetriebe verstellbar ist.The adjustment part can, however, also be arranged on an end face of the lock part, the lock part being adjustable via a toothed wheel, a toothed rack or a worm gear.

Zur Vermeidung einer seitlichen Verschiebung der Schlossteile auf dem Schlossträger können Führungen vorgesehen sein, die eine Bewegung des Schlossteils senkrecht zur Längsbewegungsrichtung der Platinen verhindern. Als Führungen kommen beispielsweise in Längsnuten eingreifende Zylinderstifte oder Passfedern in Frage, wobei die Zylinderstifte oder Passfedern vorzugsweise am Schlossteil angeordnet sind. Die Verwendung von Passfedern hat dabei den Vorteil, dass diese flächig und nicht nur linienförmig in den Nuten anliegen. Im Schlossträger können jedoch auch Aussparungen zur Aufnahme und Führung der Schlossteile vorgesehen sein.To avoid a lateral displacement of the lock parts on the lock carrier, guides can be provided which prevent a movement of the lock part perpendicular to the longitudinal direction of movement of the plates. Cylindrical pins or feather keys engaging in longitudinal grooves are possible guides, for example, the cylinder pins or feather keys preferably being arranged on the lock part. The use of feather keys has the advantage that they lie flat and not just linearly in the grooves. However, recesses for receiving and guiding the lock parts can also be provided in the lock carrier.

Der Schlossträger kann ringförmig oder ringsegmentförmig ausgebildet und das mindestens eine Schlossteil in radialer Richtung bezüglich des Schlossträgers verstellbar sein. Eine derartige Ausbildung des Platinenschlosses ist bei Rundstrickmaschinen üblich, bei denen die Platinen senkrecht zu den Nadeln bewegt werden. Die Erfindung, d.h. die unmittelbare Anordnung der Schlossteile auf dem Schlossträger unter Verzicht auf Platinenschlosssegmente bei Beibehaltung der Verstellbarkeit der Schlossteile, kann jedoch auch auf andere Platinenschlösser übertragen werden. Auch eine senkrechte Ausrichtung der Platinen gegenüber den Nadeln der Maschine ist nicht erforderlich. Das erfindungsgemäße Platinenschloss lässt sich auch bei Maschinen einsetzen, bei denen die Platinen unter einem anderen Winkel oder parallel zu den Nadeln angeordnet sind.The lock carrier can be ring-shaped or ring-segment-shaped and the at least one lock part can be adjusted in the radial direction with respect to the lock carrier. Such a design of the sinker lock is common in circular knitting machines in which the sinkers are moved perpendicular to the needles. The invention, ie the direct arrangement of the lock parts on the lock carrier, dispensing with sinker lock segments while maintaining the adjustability of the lock parts, can, however, also be transferred to other sinker locks. A vertical alignment of the blanks with respect to the needles of the machine is also not necessary. The circuit board lock according to the invention can also be used in machines where the sinkers are arranged at a different angle or parallel to the needles.

Die Erfindung betrifft außerdem eine Rundstrickmaschine mit einem erfindungsgemäßen Platinenschloss. Die Maschine kann dabei vorzugsweise eine Single-Jersey-Maschine sein und/oder eine Feinheit von mindestens 28 Nadeln/Zoll (2,54 cm) aufweisen. Besonders vorteilhaft sind Maschinen mit einer sehr hohen Feinheit von mindestens 44 Nadeln/Zoll (2,54 cm) mit einem erfindungsgemäßen Platinenschloss.The invention also relates to a circular knitting machine with a sinker lock according to the invention. The machine can preferably be a single jersey machine and / or have a fineness of at least 28 needles / inch (2.54 cm). Machines with a very high fineness of at least 44 needles / inch (2.54 cm) with a sinker lock according to the invention are particularly advantageous.

Im Folgenden wird ein bevorzugtes Ausführungsbeispiel eines erfindungsgemäßen Platinenschlosses im Vergleich zu einem Schloss nach dem Stand der Technik mit Bezug auf die Zeichnung näher erläutert.In the following, a preferred embodiment of a plate lock according to the invention is explained in more detail in comparison to a lock according to the prior art with reference to the drawing.

Das in Fig. 1 gezeigte Platinenschloss 100 nach dem Stand der Technik weist einen ringförmigen Schlossträger 101 auf, auf dessen Oberseite eine Vielzahl von Platinenschlosssegmenten 102 angeordnet sind, von denen in Fig. 1 drei beispielhaft dargestellt sind. Die Platinenschlosssegmente 102 sind fest mit dem Schlossträger 101 verschraubt. Auf ihrer Unterseite sind jeweils Platinenschlossteile 103 mit Steuerkurven für Platinen 105 angeordnet, wobei die Platinenschlossteile 103 zur Feineinstellung in radialer Richtung bezüglich des Schlossträgers 101 verschiebbar an den Schlosssegmenten 102 angeordnet sind. Zur Verstellung der Platinenschlossteile 103 sind in den Schlosssegmenten jeweils Verstellteile 104 vorgesehen, die auf der Oberseite der Schlosssegmente 102 zugänglich sind. Da die Schlosssegmente eine relativ große Bauhöhe aufweisen, ist die Sicht auf die Platinen 105 und die Zylindernadeln stark eingeschränkt. Außerdem kann sich Faserflaum zwischen den Platinen 105 und den Schlosssegmenten 102 ansammeln.This in Fig. 1 The sinker lock 100 shown according to the prior art has an annular lock carrier 101, on the upper side of which a multiplicity of sinker lock segments 102 are arranged, of which in FIG Fig. 1 three are shown as examples. The sinker lock segments 102 are firmly screwed to the lock carrier 101. On their underside, each sinker lock parts 103 with control cams for sinkers 105 are arranged, the sinker lock parts 103 being arranged on the lock segments 102 so as to be displaceable in the radial direction with respect to the lock carrier 101 for fine adjustment. To adjust the sinker lock parts 103, adjustment parts 104 are provided in the lock segments, which are accessible on the upper side of the lock segments 102. Since the lock segments have a relatively large overall height, the view of the sinkers 105 and the cylinder needles is severely restricted. In addition, fluff can collect between the sinkers 105 and the lock segments 102.

In Fig. 2 ist ein Abschnitt eines erfindungsgemäßen Platinenschlosses 10 dargestellt. Bei diesem Schloss 10 wurde auf Schlosssegmente verzichtet und stattdessen die Platinenschlossteile 3 direkt auf dem ringförmigen Schlossträger 1 montiert. Die Platinenschlossteile 3 werden dabei jeweils von einer Schraube 6 mit einer Tellerfeder 7 gegen die Oberseite des Schlossträgers 1 gedrückt. Die Schraube 6 ist dabei durch ein aus Fig. 3 ersichtliches Langloch oder Loch 8 mit einem größeren Durchmesser als der Schraubenschaft durch das Schlossteil 3 hindurchgeführt, sodass das Schlossteil 3 unter Überwindung der Reibkraft zwischen Schlossteil 3 und Schlossträger 1 in radialer Richtung des Schlossträgers 1 verschoben werden kann. Um diese radiale Verstellung zu ermöglichen, ist im Platinenschlossteil 3 ein Verstellteil 4 vorgesehen. Während der Verschiebebewegung werden die Schlossteile von Führungen 9 seitlich geführt.In Fig. 2 a section of a sinker lock 10 according to the invention is shown. In this lock 10, lock segments were dispensed with and instead the plate lock parts 3 were mounted directly on the ring-shaped lock carrier 1. The sinker lock parts 3 are each pressed against the top of the lock carrier 1 by a screw 6 with a plate spring 7. The screw 6 is through one out Fig. 3 Obvious elongated hole or hole 8 with a larger diameter than the screw shaft passed through the lock part 3 so that the lock part 3 can be moved in the radial direction of the lock carrier 1 while overcoming the frictional force between the lock part 3 and the lock carrier 1. In order to enable this radial adjustment, an adjustment part 4 is provided in the sinker lock part 3. During the sliding movement, the lock parts are guided laterally by guides 9.

Wie Fig. 3 verdeutlicht, weist das Verstellteil 4 einen Stellkopf 4.1 mit einer Öffnung 4.2 zur Aufnahme eines Steckschlüssels (nicht gezeigt) auf. Am äußeren Umfang des Stellkopfs 4.1 ist ein mit einer Skala versehener Ring 4.3 vorgesehen, um die Verstellung des Schlossteils 3 besser kontrollieren zu können. Der Stellkopf 4.1 wirkt mit einem Zylinderstift 4.4 zusammen, der in einer Spiralnut 4.5 im Verstellteil 4 geführt ist. Die seitlichen Führungen 9 werden von Zylinderstiften 9.1 gebildet, die in Längsnuten 9.2 im Schlossträger 1 geführt sind.As Fig. 3 clarified, the adjustment part 4 has an adjusting head 4.1 with an opening 4.2 for receiving a socket wrench (not shown). A ring 4.3 provided with a scale is provided on the outer circumference of the adjusting head 4.1 in order to be able to better control the adjustment of the lock part 3. The adjusting head 4.1 interacts with a cylindrical pin 4.4 which is guided in a spiral groove 4.5 in the adjustment part 4. The lateral guides 9 are formed by cylinder pins 9.1 which are guided in longitudinal grooves 9.2 in the lock carrier 1.

Fig. 4 zeigt ein zweiteiliges Schlossteil 3', das aus einem ersten, mit einem erfindungsgemäßen Verstellteil 4' versehenen Teil 3.1' und einem zweiten, auswechselbaren Teil 3.2' besteht. Die Figur zeigt die beiden Teile 3.1' und 3.2' im getrennten Zustand. Mittels einer Schraube können die Teile 3.1', 3.2' sowohl miteinander als auch mit einem hier nicht gezeigten Schlossträger verbunden werden. Mit dem Verstellteil 4' kann eine Feineinstellung des Schlossteils 3' beispielsweise zum Ausgleich von Fertigungstoleranzen vorgenommen werden. Erfordert jedoch eine Umstellung der Strickmaschine auf ein anderes Muster größere Verstellungen des Schlossteils 3', so kann der auswechselbare Teil 3.2' des Schlossteils 3' gegen ein anderes ausgetauscht werden. Der Teil 3.1' mit dem Verstellteil 4' verbleibt dagegen auf dem Schlossträger. Fig. 4 shows a two-part lock part 3 ', which consists of a first part 3.1' provided with an adjustment part 4 'according to the invention and a second, exchangeable part 3.2'. The figure shows the two parts 3.1 'and 3.2' in the separated state. The parts 3.1 ', 3.2' can be connected to one another as well as to a lock carrier, not shown here, by means of a screw. With the adjustment part 4 ', a fine adjustment of the lock part 3' can be made, for example to compensate for manufacturing tolerances. However, if a changeover of the knitting machine to a different pattern requires larger adjustments of the lock part 3 ', the exchangeable part 3.2' of the lock part 3 'can be exchanged for another. The part 3.1 'with the adjustment part 4', however, remains on the lock carrier.
