Definitions
- the invention relates to a latch needle for knitting machines, in particular for knitting machines without Einsch alone- / teeingplatinen.
- a knitting machine which has a knitting cylinder with needle channels provided on the circumference of the knitting cylinder.
- latch needles which are arranged longitudinally displaceable.
- For controlled longitudinal displacement is made of a plurality of segments existing overall annular, surrounding the knitting cylinder stationary knitting lock, which has at least two different control tracks.
- the latch needles have feet that engage the control tracks. For example, the even-numbered latch needles are moved from one control track and the odd-numbered knitting needles are moved from the other control path.
- a yarn guide is used, which is in close proximity to the driven knitting needles and can come into contact with the tongues of the knitting needles. This effect may be desired to release the tongues in their open position, i. Reserve position.
- the contact between the yarn guide and the tongues leads to wear, as a result, on the tongue, especially on the spoon, unwanted sharp edges can arise.
- the above-mentioned knitting machine does not require containment boards, the machine allows the production of very fine knits with very small stitches, because the dowel needles can be placed very close together. The space otherwise required for the boards is now available for the latch needles. However, the above-mentioned wear of the latch needles is undesirable.
- the latch needle according to the invention has on the tongue on a cam which is provided with a sliding surface.
- This cam is adapted to come into contact with corresponding sliding surfaces of a stop means of the yarn guide, for example in the form of a separately formed runner and to run along this.
- the cam can support the tongue on the sliding surface of the stop means and prevent the tongue from being pivoted out of its reserve.
- the provided on the stop means sliding surface can hold the tongue in the open position, wherein the cam of the tongue runs along this sliding surface or slides.
- the sliding surface of the cam is formed so that the sliding of the sliding surface produces flats or facets that are not bounded by sharp edges.
- the cam is located at that end of the spoon of the tongue which extends away from the stem. This is the end of the tongue furthest away from the pivotal position of the tongue.
- the cam can also be arranged at a different location, for example between the spoon and the shaft of the tongue.
- the tongue is formed symmetrically to a tongue center plane on which the pivot axis of the tongue is vertical.
- the cam is preferably arranged symmetrically to such a tongue center plane. If necessary, for example, if the direction of rotation of the knitting machine is clearly defined, the cam may alternatively be arranged asymmetrically with respect to the tongue center plane.
- the sliding surface formed on the cam is preferably somewhat convex, that is to say convexly curved both with respect to the tongue longitudinal direction and with respect to the tongue transverse direction.
- the rounding of the sliding surface can be taken differently in the longitudinal and transverse directions. However, the rounding can also be approximately spherical.
- the convex spherical sliding surface may have flats created by wear, wherein the risk of the formation of sharp edges on the sliding surface is greatly reduced, preferably does not exist.
- the preferably spherical sliding surface of the cam preferably extends beyond a plane defined by the spoon edge of the tongue.
- the spoon edge is the edge surrounding the recess of the spoon.
- the "lower edge" of the tongue head which does not have a depression, should be considered the "spoon edge”. Because the cam is raised above the rim, it provides a reserve of wear which ensures that the rim is kept away from a sliding surface of a thread guide or blade which is stationary relative to the thread guide. The rim of the bucket is prevented from touching other machine parts and wear of the rim is avoided.
- the cam is formed narrower than the spoon of the tongue.
- the width of the cam is about as large as the width of the shaft of the tongue. This makes it possible that the cam does not interfere with the knitting process.
- the cam preferably has a shorter length than the spoon. Measured in the tongue longitudinal direction, the length of the cam is preferably not greater than two-thirds of the length of the spoon. This measure also serves not to disturb the knitting process. In addition, the mass of the Tongue is only slightly increased by the cam, so that the dynamic properties of the latch needle remain good.
- FIG. 1 is a knitting point of a knitting machine illustrated.
- a yarn guide 1 is preferably held stationary on the knitting machine. At one end, it has at least one passage opening 2, which serves as an eyelet for feeding a thread 3.
- Expelled latch needles 4 (4a to 41) and 5 (5a to 5k) run along a sliding surface 6.
- a runner 7 may be provided with a sliding surface 8.
- the sliding surface 8 may be arranged with the sliding surface 6 in a common plane and form stop means for the latch needles 4, 5.
- the runner 7 may be arranged in a trapezoidal section of the thread guide 1.
- the runner 7 may be attached to the yarn guide 1 or at another stationary with respect to the knitting point of the knitting machine.
- the skid 7, as in FIG. 1 can be seen, a slightly bent end 9 having a contact surface 10.
- the sliding surfaces 6 and 8 serve to hold the tongues 4, 5 provided tongues 16 in the open position.
- the latch needle 4 has a needle body 11 with an elongated shaft 12 which is provided at one end with a hook 13.
- the hook of the elongate shaft 12 terminates in a tip 14.
- a tongue slot 15 extending in the longitudinal direction of the shaft is formed, in which a tongue 16 is pivotally mounted.
- the purpose of a tongue bearing 17 for the tongue 16 which defines a pivot axis transverse to the shaft 12 and the tongue 16.
- the latch needle 4 In this respect, this is essentially the same as a conventional latch needle.
- the tongue 16 has a shaft 18 which extends into the tongue slot 15 and is pivotally mounted on the tongue bearing 17.
- the shaft 18 is provided for this purpose with a corresponding receptacle, in which a pin or on the side walls which define the tongue slot 15, formed projections engage.
- the shaft 18 carries at its end remote from the tongue bearing 17 end a tongue head 19 which has the shape of a spoon, which, as in FIG. 3 shown, can put in corresponding formed on the side walls recesses 20, 21.
- the spoon 19 is slightly wider than the shaft 18 and joins without forming an edge or Absatztes to this.
- the hook 14 side facing the spoon 19 is provided with a recess 22, which is also referred to as "Zasche”.
- the recess 22 is as illustrated by the closed position FIG. 5 emerges, formed so that the tip 14 of the hook 13 is received in the closed position of the recess 22.
- the recess 22 is surrounded by a rim 23 which is preferably approximately in a plane.
- the projection 24 extends there along the longitudinal direction 25 of the tongue 16, which is illustrated by a line 25 which connects the shaft-side end point 26 of the recess 22 with the cam-side end point 27 of the recess 22.
- the cam 24 has a sliding surface 28 which rises above this line 25.
- the sliding surface 28 is preferably spherical, ie convex. It rises above the 25 line, as in FIG. 5 is indicated by one of the surface of the sliding surface 28 following line 29.
- the sliding surface 28 is curved with respect to the tongue longitudinal direction. In addition, it is preferably curved in the transverse direction of the tongue.
- the sliding surface 28 also rises above a plane which is defined by the edge 23 of the recess 22. This applies at least if the edge 23 itself is not curved, but lies in a plane.
- the extension 24 is smaller than the distance which is measured between the end point 26 of the tongue shaft 18 and the end point 27 of the recess 22. In other words, in the tongue longitudinal direction of the cam 24 is smaller than the length of the zasche 22.
- the tongue needle 4 described so far operates as follows:
- the needles 4a to 4l and 5a to 5k are associated with two different groups of needles driven out of different curves 30, 31. This is in FIG. 1 and additionally schematically in FIG FIG. 2 illustrated.
- the expulsion of the needle 4 follows the positions 41, 4k, etc., until the needle is retracted according to the positions 4c, 4b and 4a.
- the ejection of the needles 5 follows the positions of the needles 5h to 5d until the needle 5 is withdrawn over the positions of the needles 5, 5b and 5a again.
- the tongues 16 of the expelled Needles 4 and 5 last in the open position. To stay in this, the tongues 16 with their respective cams 24 can run along the sliding surfaces 6 and 8.
- the highest point of the sliding surface 28 with respect to the line 25 has a distance of 0.03 mm.
- the distance, ie the largest elevation of the sliding surface 28 is slightly larger.
- FIGS. 7 to 9 illustrate another embodiment of the invention.
- This refers to a hook-toothed latch needle 32.
- This has at the top of its hook 13, a recess 33 ("Zasche"), in which an edge of the tongue 34 can lay.
- the tongue 34 has, as in particular also from FIG. 9 shows, following its shaft 35 a tongue head 36 without depression on.
- the tongue head 36 merges at its free end into a cam 37.
- the tongue head 36 has a preferably straight edge 38, which in the closed position, such as FIG. 7 points into the recess of the hook lays.
- the edge 37 is in FIG. 9 illustrated in particular by dashed lines. It defines a plane 39 which extends transversely to the tongue 34 and which is perpendicular to an imaginary center plane 40 of the tongue (a same median plane 40, as well as a plane formed by the edge 23 level 39 is also at latch needle 4, 5 and Tongue 16 after Figure 1 to 6 to think, but not shown there).
- the edge 38 extends from a starting point 41 to an end point 42 and is preferably formed straight in this area.
- the cam 37 extends with its sliding surface 43, which is preferably rounded both perpendicular to the median plane 40 and within the plane 40.
- the sliding surface 43 preferably protrudes at least approximately 0.03 mm above the plane 39. It bulges in the closed position the sliding surface 43, as FIG. 7 shows, toward the hook 13 and is seen from the direction convex.
- the cam 24 or 37 both with the featured spoon-glazed needle ( FIGS. 4 to 6 ) as well as the hooked-on needle ( FIGS. 7 to 9 ), the cam 24 or 37, as shown, be arranged symmetrically to the center plane 40 as well as alternatively asymmetrically to this. Furthermore, the cam 24 or 37 can alternatively be arranged between the shaft 18 and the spoon 19 or between the shaft 35 and the tongue head 36. In all embodiments, the sliding surface 28 or 43 is arranged on one side of the cam, which faces the hook 13.

Abstract
Description
Die Erfindung betrifft eine Zungennadel für Strickmaschinen, insbesondere für Strickmaschinen ohne Einschließ- / Abschlagplatinen.The invention relates to a latch needle for knitting machines, in particular for knitting machines without Einschließ- / teeingplatinen.
Aus der
Bei dieser Anordnung wird ein Fadenführer eingesetzt, der in unmittelbarer Nachbarschaft zu den ausgetriebenen Stricknadeln steht und mit den Zungen der Stricknadeln in Berührung kommen kann. Dieser Effekt kann gewünscht sein, um die Zungen in ihrer Offenstellung, d.h. Rücklageposition zu halten. Die Berührung zwischen dem Fadenführer und den Zungen führt jedoch zu einem Verschleiß, infolgedessen an der Zunge, insbesondere an deren Löffel, unerwünschte scharfe Kanten entstehen können.In this arrangement, a yarn guide is used, which is in close proximity to the driven knitting needles and can come into contact with the tongues of the knitting needles. This effect may be desired to release the tongues in their open position, i. Reserve position. However, the contact between the yarn guide and the tongues leads to wear, as a result, on the tongue, especially on the spoon, unwanted sharp edges can arise.
Weil die oben genannte Strickmaschine ohne Einschließplatinen auskommt gestattet die Maschine die Erzeugung besonders feiner Gestricke mit sehr kleinen Maschen, denn die Zugnennadeln können sehr dicht nebeneinander angeordnet werden. Der sonst für die Platinen benötigte Bauraum steht nun für die Zungennadeln zur Verfügung. Jedoch ist der oben erwähnte Verschleiß der Zungennadeln unerwünscht.Because the above-mentioned knitting machine does not require containment boards, the machine allows the production of very fine knits with very small stitches, because the dowel needles can be placed very close together. The space otherwise required for the boards is now available for the latch needles. However, the above-mentioned wear of the latch needles is undesirable.
Davon ausgehend, ist es Aufgabe der Erfindung, eine verbesserte Zungennadel zu schaffen. Diese Aufgabe wird mit der Zungennadel nach Anspruch 1 gelöst:On this basis, it is an object of the invention to provide an improved latch needle. This object is achieved with the latch needle according to claim 1:
Die erfindungsgemäße Zungennadel weist an der Zunge einen Nocken auf, der mit einer Gleitfläche versehen ist. Dieser Nocken ist dazu geeignet, mit entsprechenden Gleitflächen eines Anschlagmittels des Fadenführers beispielsweise in Form einer gesondert ausgebildeten Kufe in Berührung zu kommen und an dieser entlang zu laufen. Dadurch kann der Nocken die Zunge an der Gleitfläche des Anschlagmittels abstützen und verhindern, dass die Zunge aus ihrer Rücklage heraus verschwenkt wird. Mit anderen Worten, die an dem Anschlagmittel vorgesehene Gleitfläche kann die Zunge in Offenstellung halten, wobei der Nocken der Zunge an dieser Gleitfläche entlang läuft oder gleitet.The latch needle according to the invention has on the tongue on a cam which is provided with a sliding surface. This cam is adapted to come into contact with corresponding sliding surfaces of a stop means of the yarn guide, for example in the form of a separately formed runner and to run along this. Thereby, the cam can support the tongue on the sliding surface of the stop means and prevent the tongue from being pivoted out of its reserve. In other words, the provided on the stop means sliding surface can hold the tongue in the open position, wherein the cam of the tongue runs along this sliding surface or slides.
An dem Nocken auftretender Verschleiß kann in der Regel toleriert werden. Außerdem ist die Gleitfläche des Nockens so ausgebildet, dass durch das Gleiten der Gleitfläche Abflachungen oder Facetten entstehen, die nicht von scharfen Kanten berandet sind.Wear occurring on the cam can generally be tolerated. In addition, the sliding surface of the cam is formed so that the sliding of the sliding surface produces flats or facets that are not bounded by sharp edges.
Vorzugsweise ist der Nocken an demjenigen Ende des Löffels der Zunge angeordnet, die sich von dem Schaft weg erstreckt. Dies ist das von der Schwenklagerung der Zunge am weitesten weg liegende Ende der Zunge. Alternativ kann der Nocken aber auch an einer anderen Stelle, beispielsweise zwischen dem Löffel und dem Schaft der Zunge angeordnet werden.Preferably, the cam is located at that end of the spoon of the tongue which extends away from the stem. This is the end of the tongue furthest away from the pivotal position of the tongue. Alternatively, however, the cam can also be arranged at a different location, for example between the spoon and the shaft of the tongue.
Vorzugsweise ist die Zunge symmetrisch zu einer Zungen-Mittelebene ausgebildet, auf der die Schwenkachse der Zunge senkrecht steht. Insbesondere ist vorzugsweise der Nocken symmetrisch zu eine solchen Zungen-Mittelebene angeordnet. Bei Bedarf, zum Beispiel, wenn die Drehrichtung der Strickmaschine eindeutig festgelegt ist, kann der Nocken alternativ aber auch asymmetrisch bezüglich der Zungen-Mittelebene angeordnet sein.Preferably, the tongue is formed symmetrically to a tongue center plane on which the pivot axis of the tongue is vertical. In particular, the cam is preferably arranged symmetrically to such a tongue center plane. If necessary, for example, if the direction of rotation of the knitting machine is clearly defined, the cam may alternatively be arranged asymmetrically with respect to the tongue center plane.
Die an dem Nocken ausgebildete Gleitfläche ist vorzugsweise etwas ballig, d.h. sowohl bezüglich der Zungenlängsrichtung als auch bezüglich der Zungenquerrichtung konvex gewölbt ausgebildet. Die Rundung der Gleitfläche kann in Längs- und Querrichtung unterschiedlich getroffen sein. Die Rundung kann jedoch auch etwa sphärisch sein. Die konvexe ballige Gleitfläche kann durch Verschleiß erzeugte Abflachungen aufweisen, wobei die Gefahr der Bildung von scharfen Kanten an der Gleitfläche stark reduziert ist, vorzugsweise nicht besteht.The sliding surface formed on the cam is preferably somewhat convex, that is to say convexly curved both with respect to the tongue longitudinal direction and with respect to the tongue transverse direction. The rounding of the sliding surface can be taken differently in the longitudinal and transverse directions. However, the rounding can also be approximately spherical. The convex spherical sliding surface may have flats created by wear, wherein the risk of the formation of sharp edges on the sliding surface is greatly reduced, preferably does not exist.
Die vorzugsweise ballige Gleitfläche des Nockens erstreckt sich vorzugsweise über eine von dem Löffelrand der Zunge definierte Ebene hinaus. Bei einer löffelgezaschten Nadel, die eine Zunge aufweist, deren Löffel eine Vertiefung zur Aufnahme des Hakens hat, ist der Löffelrand, der die Vertiefung des Löffels umgebende Rand. Bei einer hakengezaschten Nadel (d.h. eine Nadel, deren Haken eine Vertiefung zur Aufnahme einer unteren Kante des Kopfes der Zunge aufweist) ist als "Löffelrand" die untere Kante des Zungenkopfes anzusehen, der hier keine Vertiefung aufweist. Weil der Nocken über den Rand erhaben ist, stellt er eine Verschleißreserve dar, die sicherstellt, dass der Rand von einer Gleitfläche eines Fadenführers oder einer Kufe ferngehalten wird, die relativ zu dem Fadenführer ortsfest angeordnet ist. Es wird verhindert, dass der Rand des Löffels andere Maschinenteile berührt und ein Verschleiß des Randes wird vermieden.The preferably spherical sliding surface of the cam preferably extends beyond a plane defined by the spoon edge of the tongue. In a spoon-glazed needle having a tongue whose spoon has a recess for receiving the hook, the spoon edge is the edge surrounding the recess of the spoon. In the case of a hooked-on needle (i.e., a needle whose hook has a recess for receiving a lower edge of the head of the tongue), the "lower edge" of the tongue head, which does not have a depression, should be considered the "spoon edge". Because the cam is raised above the rim, it provides a reserve of wear which ensures that the rim is kept away from a sliding surface of a thread guide or blade which is stationary relative to the thread guide. The rim of the bucket is prevented from touching other machine parts and wear of the rim is avoided.
Vorzugsweise ist der Nocken schmaler als der Löffel der Zunge ausgebildet. Vorzugsweise ist die Breite des Nockens etwa so groß wie die Breite des Schafts der Zunge. Dadurch wird ermöglicht, dass der Nocken den Strickvorgang nicht stört.Preferably, the cam is formed narrower than the spoon of the tongue. Preferably, the width of the cam is about as large as the width of the shaft of the tongue. This makes it possible that the cam does not interfere with the knitting process.
Der Nocken weist vorzugsweise eine geringere Länge als der Löffel auf. In Zungenlängsrichtung gemessen ist die Länge des Nockens vorzugsweise nicht größer als zwei Drittel der Länge des Löffels. Auch diese Maßnahme dient dazu, den Strickvorgang nicht zu stören. Außerdem wird die Masse der Zunge durch den Nocken insoweit nur geringfügig erhöht, so dass die dynamischen Eigenschaften der Zungennadel gut bleiben.The cam preferably has a shorter length than the spoon. Measured in the tongue longitudinal direction, the length of the cam is preferably not greater than two-thirds of the length of the spoon. This measure also serves not to disturb the knitting process. In addition, the mass of the Tongue is only slightly increased by the cam, so that the dynamic properties of the latch needle remain good.
