Definitions
- the invention relates to a needle weaving machine, in particular a needle ribbon weaving machine, with delayed weft insertion and applications thereto.
- Needle ribbon looms can - as in the WO 94/26964 A1 and the WO 2012/163571 A2 proposed - also several, interchangeable weft threads - preferably with weft threads of different colors, but also with weft threads of different materials or material thicknesses - which can then be exchanged by changing the weft thread, in the case of WO 2012/163571 A2 using a shaft frame.
- WO 2017/042015 A1 A weaving machine is presented in which knitted or laid threads are incorporated.
- the mechanical connection between the main shaft of the needle belt weaving machine and the weft thread insertion is removed and it is proposed to carry out the weft thread movement using a linear actuator or a rotary actuator.
- the problem inherent in all of these applications is that the weft thread insertion needle should not enter the shed too early, either to simply have a shed that is already more open or to have more time to change the weft thread or the puncture to ensure the knitting or laying threads are safe and trouble-free.
- the easiest way to achieve the goal would be to simply let the weft needle move a certain way outside the shed. But this would have the big disadvantage, that uselessly long distances and also disadvantageous large accelerations would occur, which must be avoided - especially at high weaving speeds.
- the object of the invention is to propose a needle weaving machine, in particular a needle ribbon weaving machine, in which the weft needle can be inserted into the shed late without having to accept the disadvantages mentioned above.
- the object of the invention is achieved by a machine according to claim 1.
- the measures of the invention first of all have the consequence that with such a drive of the weft needle, in which a toggle lever system is arranged between the crank drive and the weft shaft lever, the movement of the weft shaft is distorted.
- the movement of the weft needles, which are driven by the weft shaft via a second lever system, is changed by the effect of the toggle lever in such a way that they enter the shed with a delay or exit from it prematurely. They also perform a small return stroke movement when they are outside the shed.
- the shed opening at the point where the weft needle enters the shed is still very small.
- the compartment opening in the weft needle drive according to the present invention is already approximately twice as large. This increases security against under- or over-stitching warp threads that tend to cling or that tend to stick to each other due to electrostatic charge.
- the weaving process becomes more reliable and the fabric produced has much fewer weaving defects.
- the reed With a conventional weft needle drive, the reed has only moved very slightly away from the reed stop point at the time the weft needle enters the shed. With the measures of the invention, however, it results that the reed has already moved significantly further away from the reed stop by the time the weft needle enters the shed. This results in a further advantage that the weft needle radius can be chosen to be smaller without the weft needle colliding with the reed in the course of its movement through the shed. With a smaller weft needle radius, a more compact design of the weaving point is possible and the mechanical load on the weft needle drive is reduced (smaller mass to be accelerated).
- the weft needle drive according to the present invention is also advantageous in a machine with weft thread change: As in WO2012/163571 described, the weft threads to be read into the weft needle provided with a fork are brought into the read-in or read-out position by means of the movement of selected shafts.
- the weft needle drive according to the state of the art it is not possible to use the normal shaft change times for this. Rather, the shaft change time must be selected earlier when reading out and later when reading in. This is not a problem with electronically controlled shafts. With mechanically operated shafts, special eccentrics or chain links are required, and setting up the machine is correspondingly complicated.
- the delayed entry of the weft needle into the shed is also very advantageous in a machine that is equipped with a device for incorporating knitted threads is.
- this device at least one needle punch pierces the open shed from above if necessary and brings at least one knitted or effect thread into the lower shed in such a way that it is pierced by the weft needle and thus integrated into the fabric.
- the needle puncher has little time available for the piercing movement (typically approx. 90 degrees machine angle), as he can only begin this after the sheet has stopped and must already be sufficiently deep in the lower compartment before crossing with the weft needle.
- the delayed insertion of the weft needle increases the available time by approx. 25%, which allows the needle punch to penetrate deeper and thus a larger and more reliable knitting thread compartment.
- FIG 1 is an embodiment of the invention, namely a weaving machine with the reed 10, the drive motor 12, the main shaft 45, which drives a crank drive 13, a warp thread feeder 14, a shed forming device 16, which is suitable for forming a shed 18.
- the shed 18 includes the weaving point 15 for producing the fabric 20 by inserting a weft thread 24 by means of a weft needle insertion device 40 having a weft needle 42.
- the weft needle 42 is driven by the weft shaft lever 44, which is connected to the weft lever system 46 by means of the toggle lever system 46 Main shaft 45 or the crank drive 13 is connected.
- the inventive design according to the present exemplary embodiment differs from a weaving machine according to the prior art cited here Figure 2 in particular by connecting the weft needle drive to the main shaft 45 by means of the toggle lever system 46.
- Fig. 5 or 5a and Fig. 6 and 6a each show a top view of the weaving area and a side view of the open shed at the time at which the weft needle enters the shed.
- the shed opening h at the point where the weft needle enters the weaving shed 18 is still very small, as can be seen from the Figures 6 visible to us 6a.
- the compartment opening h in the weft drive according to the exemplary embodiment of the invention is already approximately twice as large as in the Figures 5 and 5a can be removed. This increases the security against under- or over-stitching warp threads that tend to cling or that can stick to one another due to electrostatic charge.
- Fig. 6 It can be seen that with the conventional weft needle drive, the reed 10 has only moved very slightly away from the reed stop point at the time the weft needle enters the shed (dimension a in Fig. 6 ). In Fig. 5 It can be seen that the reed 10 has already moved significantly further away from the reed stop at the time the weft needle enters the shed. This results in a further advantage that the weft needle radius R can be chosen to be smaller without the weft needle 42 colliding with the reed 10 in the course of its movement through the shed 18. With a smaller weft needle radius R, a more compact design is available Weaving is possible, and the mechanical load on the weft needle drive is reduced due to the smaller mass to be accelerated.
- the application is a simple, process-reliable weft thread change without having to forego the properties and advantages described above according to the above exemplary embodiment.
- the weft drive according to this exemplary embodiment is used in a weaving machine with weft thread change.
- the weft threads to be read into the weft needle provided with a fork are brought into the read-in or read-out position by means of the movement of selected shafts 32 and 35. But with such a shot drive it is - as if from the Figures 10a, 10b and 11a to 11i - it is not possible to use the normal shaft change times for this.
- FIG. 8a In Figure 8a are weft needle movement and in Fig. 8b the strokes of the two weft thread control shafts 32 and 35 or selection needles 36 and 33 are recorded.
- the zero line of the vertical axis of Fig. 8b corresponds to this Height of the plane of movement of the weft needle 42.
- the first weft thread is read out in position A, at approximately 325 degrees machine angle, at a time when the weft needle is in the return stroke movement.
- the corresponding control shaft 35 or the selection needle 33 connected to it are in downward movement at this point in time and are located slightly below the weft needle (height -H A ).
- Figure 9d shows how weft thread 37 jumps into the fork 43 when it crosses the distance KL during its renewed movement away from the fabric. See also position E in Fig. 8a or stroke H E in Figure 8b . Weft thread 37 then remains in the fork 43 and is inserted into the compartment until the control shaft 32 or the selection needle 36 connected to it move downwards again.
- the selection needle 36 When the weft needle moves back towards the fabric after the reversal point, the selection needle 36 has already moved up so far that the weft thread 37 presented is pierced by the weft needle 42 and is also not taken along by the fork 43 (see Figure 11g and 11 a.m ). The weft needle moves into the compartment without a weft thread - the weft exchange process was not successful.
- FIG. 12 Another exemplary embodiment is in Figure 12 shown and, with the measures of the invention, causes a more reliable piercing of a needle punch 52 in a machine with the incorporation of knitted threads 60.
- the delayed entry of the weft needle 42 into the shed 18 is very advantageous in a machine that is equipped with a device for incorporating knitted threads 60 is provided.
- this device at least one needle punch 52 pierces the open shed 18 from above if necessary and brings a knitted or effect thread 60 into the lower compartment in such a way that it is pierced by the weft needle 42 and thus tied into the fabric 20.
- the needle punch 52 pivots synchronously with the reed 10 forwards and backwards in the warp direction.
- the needle punch 52 has little time available for the piercing movement (typically approx. 90 degrees machine angle), since it can only begin after the sheet has stopped and must already be sufficiently deep in the lower compartment 61 before crossing with the weft needle 42. Due to the delayed insertion of the weft needle, the available time is increased by approximately 25%, which allows the needle punch 52 to penetrate deeper and thus a larger and more reliable knitting thread compartment.

Description
Die Erfindung betrifft eine Nadelwebmaschine, insbesondere eine Nadelbandwebmaschine, mit verzögertem Schusseintrag sowie Anwendungen dazu.The invention relates to a needle weaving machine, in particular a needle ribbon weaving machine, with delayed weft insertion and applications thereto.
Bei Nadelbandwebmaschinen ist der Antrieb der Schussnadelbewegung seit langem ein im Stand der Technik erörtertes Problem. Dabei wird beispielsweise in der
Nadelbandwebmaschinen können - wie in der
Aufgabe der Erfindung ist es, eine Nadelwebmaschine, insbesondere eine Nadelbandwebmaschine, vorzuschlagen, bei der der Schussnadeleintrag in das Webfach spät erfolgen kann, ohne dafür die oben genannten Nachteile in kaufnehmen zu müssen.The object of the invention is to propose a needle weaving machine, in particular a needle ribbon weaving machine, in which the weft needle can be inserted into the shed late without having to accept the disadvantages mentioned above.
Die Aufgabe der Erfindung wird dabei durch eine Maschine nach Anspruch 1 gelöst. Dabei haben die Massnahmen der Erfindung zunächst einmal zur Folge, dass bei einem solchen Antrieb der Schussnadel, bei dem zwischen Kurbeltrieb und Schusswellenhebel ein Kniehebelsystem angeordnet ist, die Bewegung der Schusswelle verzerrt ist. Die von der Schusswelle über ein zweites Hebelsystem angetriebenen Schussnadeln werden durch die Wirkung des Kniehebels in ihrer Bewegung derart verändert, dass sie verzögert ins Webfach eintreten bzw. verfrüht daraus wieder austreten. Zudem führen sie eine kleine Rückhubbewegung aus, wenn sie sich ausserhalb des Webfaches befinden. Damit ergeben sich - gemäss der oben genannten Aufgabenstellung - die folgenden Vorteile, nämlichThe object of the invention is achieved by a machine according to claim 1. The measures of the invention first of all have the consequence that with such a drive of the weft needle, in which a toggle lever system is arranged between the crank drive and the weft shaft lever, the movement of the weft shaft is distorted. The movement of the weft needles, which are driven by the weft shaft via a second lever system, is changed by the effect of the toggle lever in such a way that they enter the shed with a delay or exit from it prematurely. They also perform a small return stroke movement when they are outside the shed. This results in the following advantages - in accordance with the above-mentioned task - namely
Beim Schussnadelantrieb gem. Stand der Technik ist die Fachöffnung an der Stelle, wo die Schussnadel ins Webfach eintritt, noch sehr klein. Im Vergleich dazu ist die Fachöffnung beim Schussnadelantrieb gemäss der vorliegenden Erfindung bereits ca. doppelt so gross. Dadurch wird die Sicherheit gegen Unter- oder Überstechen von Kettfäden, die zum Klammern neigen oder die wegen elektrostatischer Aufladung gerne aneinander kleben bleiben, erhöht. Der Webvorgang wird zuverlässiger und das erzeugte Gewebe weist viel weniger Webfehler auf.With the weft needle drive according to the state of the art, the shed opening at the point where the weft needle enters the shed is still very small. In comparison, the compartment opening in the weft needle drive according to the present invention is already approximately twice as large. This increases security against under- or over-stitching warp threads that tend to cling or that tend to stick to each other due to electrostatic charge. The weaving process becomes more reliable and the fabric produced has much fewer weaving defects.
Bei einem herkömmlichen Schussnadelantrieb hat sich das Webblatt zum Zeitpunkt des Eintritts der Schussnadel ins Webfach erst sehr wenig vom Blattanschlagpunkt weg bewegt. Mit den Massnahmen der Erfindung ergibt sich aber, dass das Webblatt zum Zeitpunkt des Facheintritts der Schussnadel schon deutlich weiter vom Blattanschlag weg bewegt hat. Daraus ergibt sich als weiteren Vorteil, dass der Schussnadelradius kleiner gewählt werden kann, ohne dass die Schussnadel im Laufe ihrer Bewegung durch das Webfach mit dem Webblatt kollidiert. Mit kleinerem Schussnadelradius ist eine kompaktere Bauweise der Webstelle möglich, und die mechanische Belastung des Schussnadelantriebs wird reduziert (kleinere zu beschleunigende Masse).With a conventional weft needle drive, the reed has only moved very slightly away from the reed stop point at the time the weft needle enters the shed. With the measures of the invention, however, it results that the reed has already moved significantly further away from the reed stop by the time the weft needle enters the shed. This results in a further advantage that the weft needle radius can be chosen to be smaller without the weft needle colliding with the reed in the course of its movement through the shed. With a smaller weft needle radius, a more compact design of the weaving point is possible and the mechanical load on the weft needle drive is reduced (smaller mass to be accelerated).
Der Schussnadelantrieb gemäss der vorliegenden Erfindung ist auch bei einer Maschine mit Schussfadenwechsel vorteilhaft: Wie in
Der verzögerte Eintritt der Schussnadel in das Webfach ist auch sehr vorteilhaft bei einer Maschine, die mit einer Vorrichtung zum Einarbeiten von Wirkfäden versehen ist. Bei dieser Vorrichtung sticht mindestens ein Lochnadelstecher bei Bedarf von oben in das geöffnete Webfach ein und bringt mindestens einen Wirk- oder Effektfäden derart ins Unterfach, dass er von der Schussnadel überstochen und damit ins Gewebe eingebunden wird. Dem Lochnadelstecher steht für die Einstechbewegung wenig Zeit zur Verfügung (typischerweise ca. 90 Grad Maschinenwinkel), da er diese erst nach dem Blattanschlag beginnen kann und sich vor dem Kreuzen mit der Schussnadel bereits genügend tief im Unterfach befinden muss. Durch den verzögerten Schussnadeleintrag wird die zur Verfügung stehende Zeit um ca. 25% vergrössert, was ein tieferes Einstechen des Lochnadelstechers und damit ein grösseres und prozesssichereres Wirkfadenfach erlaubt.The delayed entry of the weft needle into the shed is also very advantageous in a machine that is equipped with a device for incorporating knitted threads is. In this device, at least one needle punch pierces the open shed from above if necessary and brings at least one knitted or effect thread into the lower shed in such a way that it is pierced by the weft needle and thus integrated into the fabric. The needle puncher has little time available for the piercing movement (typically approx. 90 degrees machine angle), as he can only begin this after the sheet has stopped and must already be sufficiently deep in the lower compartment before crossing with the weft needle. The delayed insertion of the weft needle increases the available time by approx. 25%, which allows the needle punch to penetrate deeper and thus a larger and more reliable knitting thread compartment.
