Definitions
- the invention relates to a weaving machine for the production of woven material with incorporated effect threads by means of a multiplicity of needles.
- a weaving machine which, by means of a warp-laying device, can be moved laterally around one or more warp threads of the base fabric and is thus able to tie off additional threads, there called laying threads, on the base fabric.
- the loom is the EP 2 395 140 A1 well suited, especially for those in the EP 2 395 140 A1 mentioned applications.
- a retaining hook - originally also called a spike, but which has nothing to do with the spike referred to here and in the following, since it lacks the connection to the additional thread - is proposed, which, however, due to its low flexibility, is only used for an additional thread (laying thread) suitable is.
- WO 2013/107571 A2 a weaving machine with a device for forming additional weft effects is known, but this has proven to be disadvantageous and the object of the invention is to overcome the disadvantages.
- the WO 2013/107571 A2 namely, it is proposed that vertically and in weft direction displaceable guide needles are arranged between reed and shedding device, which can bring effect threads into the lower shed so that the weft insertion element can move through the effect thread loop formed thereby.
- a first fundamental disadvantage of this device is that the effect thread loops become smaller and smaller, the greater the displacement strokes of the guide needles in the weft direction. The weft insertion element can then no longer move reliably or at all through the fancy yarn loops.
- a second fundamental disadvantage is that the reed is open at the top and the upper frame of the reed is missing. As a result, the reed teeth can bend in the weft direction even with a small force, which leads to warp density differences in the fabric.
- a weaving machine in which a comb shaft is provided with a plurality of teeth with intermediate spaces for guiding the knitting threads.
- the comb shaft (10) which is displaceable transversely to the warp thread direction and rotatable about an axis in the direction of the rail, is arranged transversely to the warp thread direction behind the beating position of the reed.
- the teeth of the comb shaft have projections which are designed such that the teeth can hold the knitting threads in at least one rotational position of the comb shaft. But there are applications in which a - in principle quite complex - comb shaft is superfluous.
- the object of the invention is to improve a weaving machine - with or without a comb shaft - which is suitable for the production of woven material with incorporated knitting or laying threads.
- the improvement should aim at a drive concept for the effect needles in which the above-mentioned disadvantages, in particular the potential disruption of the reed by the needle piercer, are avoided.
- the object is achieved by the machine according to claim 1.
- the measures of the invention initially have the consequence that the needle prick can be easily and safely brought out of the movement profile of the reed without this at any point in time of the machine cycle. A sufficiently large shed can thus be guaranteed.
- each of the carriers is assigned a first transmission means, preferably a first toothed belt, by means of which a preferably rotating movement of a first actuator is initially transmitted to a stationary, rotatable shaft and the first rotatable shafts of all carriers are rotatably mounted on a common axis that can be rotated with respect to the loom, preferably the said carrier pivot axis.
- each of the carriers is assigned a second rotatable shaft which is pivotable with respect to the first shaft.
- the rotary movements of the first shaft are each transmitted to the second shaft by means of second transmission means, preferably by means of toothed belts. It is furthermore advantageous if a transmission means, preferably a toothed belt, is assigned to each carrier, by means of which the said rotational movement is transmitted into the lowering and lifting movement of the carrier.
- the second, rotatable shafts are arranged so that they can be axially displaced relative to the respective second transmission means.
- the second pivoting process for "pivoting out” the carrier and piercing needle system could be driven independently.
- the second pivoting device is synchronized with the mentioned first pivoting device, for example by means of a mechanical connection.
- the advantageously plate-shaped or rail-shaped carriers can be arranged inclined to one another in such a way that the lines of movement of the needle prick approach one another or even cross one another when they are immersed. This ensures a minimal space requirement for the piercing needles between the weft insertion device and the reed.
- the first actuators are regulated by regulators, preferably electronic regulators, in such a way that they follow a movement curve predetermined by a control device.
- the stroke movements of the needle carriers and / or the rotary movement of one of the shafts connected to them and / or the actuating movement of the first actuating drives can be measured by means of sensors and reported back to the controllers of the first actuating drives.
- the second actuating drives can be regulated by means of regulators, preferably electronic regulators, in such a way that they follow a movement curve predetermined by a control device.
- sliding supports are provided which, on the one hand, can be moved transversely to the warp thread direction by means of the second actuating drives and the joints and, on the other hand, the supports are arranged on the sliding supports so that they can be moved up and down along the sliding supports.
- a swivel bracket, a sliding bracket and a needle carrier are provided.
- the pivoting support only takes part in the pivoting movement in and against the warp thread direction, while the sliding support takes part in both the pivoting and the sliding movement.
- the needle carrier is then exposed to the pivoting movement, the sliding movement, essentially transversely to the warp thread direction, and the lifting movement, essentially vertically.
- pivoting movement of the carrier axis of rotation is generated with an electronically controlled third actuator which follows a movement curve predetermined by a control device.
- the above-mentioned configurations initially relate to ribbon looms, for example with a weft needle.
- the technology according to the invention can advantageously be used on wider weaving machines in that a gripper, a pneumatic means or - quite conventionally - a shuttle is provided as the weft insertion means.
- FIG 1 a first embodiment of the present invention is shown.
- Weaving machine for the production of woven goods with incorporated knitting threads 6, comprises, as usual, a shedding device for forming a shed 4 from warp threads 2, 3 with at least one upper shed and one lower shed, a Weft insertion device 7 for inserting weft threads 5, a reed 1 for beating up inserted weft threads 5, a first pivoting device 10 for pivoting the reed 1 towards the woven material and for pivoting it back.
- the swivel device is operatively connected to the main shaft of the loom.

- This comprises a feed device for the knitting thread 6 for each knitting thread 6, and a needle piercer 12 with a thread guide eyelet for the shed that can be dipped between warp threads 2 into the shed below the insertion path of the weft insertion device 7 Knitting thread 6.
- the machine furthermore comprises carriers 14, 14a, which are arranged above and transversely to the warp threads 2 on the goods take-off side and one behind the other in the warp thread direction 20. On each of the supports 14, one or more needle pricks 12 are arranged next to one another.
- a second pivoting device 24 is assigned to the carriers 14, 14a, by means of which the carriers 14, 14a can be pivoted together in the warp thread direction 20 on a carrier pivot axis 26 in and against the warp direction 20 so that they and the needle piercers 12 connected to them the reed 1 not affect at any time.

Furthermore, a first toothed belt 28, 28a is assigned to each carrier, by means of which the rotary movement is initially transmitted to a stationary, rotatable shaft 30, 30a.

Description

Dabei ist das Problem zu beachten, dass, insbesondere bei einer Vielzahl von hintereinander angeordneten Lochnadelstechern diese auch im angehobenen Zustand das Webblatt zu stören vermögen. Andererseits erscheint es wichtig, das Webblatt soweit vom Warenanschlag bewegen zu können, dass ein genügend grosses Webfach entstehen kann und sowohl für den Schussvorgang wie auch den Einstechvorgang genügend Raum bleibt.In this case, the problem must be taken into account that, in particular with a large number of piercing needles arranged one behind the other, these are able to disturb the reed even in the raised state. On the other hand, it appears important to be able to move the reed away from the material stop so that a sufficiently large shed can be created and there is enough space for both the weft process and the piercing process.
Weiterhin hat sich herausgestellt, dass der Antrieb der Effektnadeln, wie er beispielsweise in der
Wenn die Webmaschine hohe Webgeschwindigkeiten erreichen soll, erscheint somit ein verbessertes Antriebskonzept der Elemente für die Effektnadeln gegenüber dem Stand der Technik erforderlich zu sein.If the loom is to achieve high weaving speeds, an improved drive concept of the elements for the effect needles over the prior art appears to be necessary.
Aufgabe der Erfindung ist es, eine Webmaschine- mit oder ohne eine Kammwelle - zu verbessern, die zur Herstellung von Webgut mit einarbeiteten Wirk- oder Legefäden geeignet ist. Die Verbesserung soll dabei auf ein Antriebskonzept der Effektnadeln zielen, bei dem die oben erwähnten Nachteile, insbesondere die potentielle Störung des Webblattes durch die Lochnadelstecher, vermieden werden.The object of the invention is to improve a weaving machine - with or without a comb shaft - which is suitable for the production of woven material with incorporated knitting or laying threads. The improvement should aim at a drive concept for the effect needles in which the above-mentioned disadvantages, in particular the potential disruption of the reed by the needle piercer, are avoided.
Die Aufgabe wird bei der eingangs genannten Webmaschine durch die Maschine nach Anspruch 1 gelöst. Dabei haben die Massnahmen der Erfindung zunächst einmal zur Folge, dass die Lochnadelstecher einfach und sicher aus dem Bewegungsprofil des Webblattes gebracht werden können, ohne dieses zu irgendeinem Zeitpunkt des Maschinenzyklus zu beschränken. Somit kann ein genügend grosses Webfach gewährleistet werden.In the case of the loom mentioned at the beginning, the object is achieved by the machine according to claim 1. The measures of the invention initially have the consequence that the needle prick can be easily and safely brought out of the movement profile of the reed without this at any point in time of the machine cycle. A sufficiently large shed can thus be guaranteed.
Vorteilhafte Ausgestaltungen der Webmaschine sind in den abhängigen Ansprüchen beschrieben.Advantageous refinements of the loom are described in the dependent claims.
Vorteilhaft ist es insbesondere, wenn sowohl der Einstechvorgang durch das Absenken der Träger wie auch der Positioniervorgang durch das Verschieben der Träger mittels- in Bezug auf die Webmaschine - ortsfesten Antrieben durchgeführt werden. Dabei ist es vorteilhaft im Sinne einer einfachen Ausführung, wenn jedem der Träger ein erstes Übertragungsmittel, vorzugsweise ein erster Zahnriemen zugeordnet ist, mittels dessen eine vorzugsweise drehende Bewegung eines ersten Stellantriebs zunächst auf eine ortsfeste, drehbare Welle übertragen wird und die ersten drehbaren Wellen aller Träger auf einer gemeinsamen, gegenüber der Webmaschine drehbaren Achse, vorzugsweise der genannten Trägerschwenkachse, drehbar gelagert sind. Vorteilhafterweise wird jedem der Träger eine zweite, gegenüber der ersten Welle schwenkbare, drehbare Welle zugeordnet ist. Dabei werden die Drehbewegungen der ersten Welle jeweils mittels zweiter Übertragungsmittel, vorzugsweise mittels Zahnriemen, auf die zweite Welle übertragen. Dabei ist es weiterhin vorteilhaft, wenn jedem Träger ein Übertragungsmittel vorzugsweise ein Zahnriemen zugeordnet ist, mittels deren die genannte Drehbewegung in die Absenk- und Anhebebewegung des Trägers übertragen wird.It is particularly advantageous if both the piercing process by lowering the carrier and the positioning process by moving the carrier are carried out by means of stationary drives in relation to the loom. It is advantageous in the sense of a simple embodiment if each of the carriers is assigned a first transmission means, preferably a first toothed belt, by means of which a preferably rotating movement of a first actuator is initially transmitted to a stationary, rotatable shaft and the first rotatable shafts of all carriers are rotatably mounted on a common axis that can be rotated with respect to the loom, preferably the said carrier pivot axis. Advantageously, each of the carriers is assigned a second rotatable shaft which is pivotable with respect to the first shaft. The rotary movements of the first shaft are each transmitted to the second shaft by means of second transmission means, preferably by means of toothed belts. It is furthermore advantageous if a transmission means, preferably a toothed belt, is assigned to each carrier, by means of which the said rotational movement is transmitted into the lowering and lifting movement of the carrier.
Vorteilhaft im Sinne dieser einfachen Ausführung ist es weiterhin, wenn die zweiten, drehbaren Wellen axial verschiebbar gegenüber dem jeweiligen zweiten Übertragungsmittel angeordnet sind.In terms of this simple embodiment, it is also advantageous if the second, rotatable shafts are arranged so that they can be axially displaced relative to the respective second transmission means.
Grundsätzlich könnte der zweite Schwenkvorgang zum "Herausschwenken" des Träger- und Einstechnadelsystem unabhängig angetrieben werden. Vorteilhaft erscheint es aber, wenn die zweite Schwenkvorrichtung mit der genannten ersten Schwenkvorrichtung - beispielsweise mittels einer mechanischen Verbindung - synchronisiert ist.In principle, the second pivoting process for "pivoting out" the carrier and piercing needle system could be driven independently. However, it appears to be advantageous if the second pivoting device is synchronized with the mentioned first pivoting device, for example by means of a mechanical connection.
Die vorteilhafterweise platten- oder schienenförmigen Träger können so gegeneinander geneigt angeordnet sein, dass sich die Bewegungslinien der Lochnadelstecher beim Eintauchen einander annähern oder sich gar kreuzen. Dies gewährleistet einen minimalen Platzbedarf der Einstechnadeln zwischen der Schusseintragsvorrichtung und dem Webeblatt.The advantageously plate-shaped or rail-shaped carriers can be arranged inclined to one another in such a way that the lines of movement of the needle prick approach one another or even cross one another when they are immersed. This ensures a minimal space requirement for the piercing needles between the weft insertion device and the reed.
Vorteilhaft kann es sein, wenn die ersten Stellantriebe mittels Reglern, vorzugsweise elektronischen Reglern, derart geregelt sind, dass sie einer von einer Steuereinrichtung vorgegebenen Bewegungskurve folgen. Dabei können die Hubbewegungen der Lochnadelträger und/oder die Drehbewegung einer der mit ihnen verbundenen Wellen und/oder die Stellbewegung der ersten Stellantriebe mittels Sensoren gemessen und den Reglern der ersten Stellantriebe zurückgemeldet werden. Weiterhin können die zweiten Stellantriebe mittels Reglern, vorzugsweise elektronischen Reglern, derart geregelt sind, dass sie einer von einer Steuereinrichtung vorgegebenen Bewegungskurve folgen. In einer vorteilshaften Ausgestaltung der Erfindung sind Verschiebeträger vorgesehen, die einerseits mittels der zweiten Stellantriebe und der Gelenke quer zur Kettfadenrichtung verfahrbar sind und andererseits die Träger an den Verschiebeträgern so angeordnet sind, dass sie entlang der Verschiebeträger abwärts und aufwärts bewegbar sind. Bei dieser Ausführung ist also jeweils ein Schwenkträger, ein Verschiebeträger und ein Lochnadelträger vorgesehen. Der Schwenkträger macht dabei nur die Schwenkbewegung in und entgegen der Kettfadenrichtung mit, während der Verschiebeträger jeweils sowohl die Schwenk- wie auch die Verschiebebewegung mitmacht. Schliesslich ist der Lochnadelträger dann - der Schwenkbewegung, der Verschiebebewegung - im Wesentlichen quer zur Kettfadenrichtung - und der Hubbewegung - im Wesentlichen vertikal - ausgesetzt. Dadurch ist es einfach möglich, dass der Verfahrhub der Verschiebeträger quer zur Kettrichtung mittels eines auf dem Schwenkträger angeordneten Hubsensors gemessen und den Reglern der zweiten Stellantriebe zurückgemeldet wird.It can be advantageous if the first actuators are regulated by regulators, preferably electronic regulators, in such a way that they follow a movement curve predetermined by a control device. The stroke movements of the needle carriers and / or the rotary movement of one of the shafts connected to them and / or the actuating movement of the first actuating drives can be measured by means of sensors and reported back to the controllers of the first actuating drives. Furthermore, the second actuating drives can be regulated by means of regulators, preferably electronic regulators, in such a way that they follow a movement curve predetermined by a control device. In an advantageous embodiment of the invention, sliding supports are provided which, on the one hand, can be moved transversely to the warp thread direction by means of the second actuating drives and the joints and, on the other hand, the supports are arranged on the sliding supports so that they can be moved up and down along the sliding supports. In this embodiment, a swivel bracket, a sliding bracket and a needle carrier are provided. The pivoting support only takes part in the pivoting movement in and against the warp thread direction, while the sliding support takes part in both the pivoting and the sliding movement. Finally, the needle carrier is then exposed to the pivoting movement, the sliding movement, essentially transversely to the warp thread direction, and the lifting movement, essentially vertically. As a result, it is easily possible for the travel stroke of the sliding supports to be measured transversely to the warp direction by means of a stroke sensor arranged on the pivoting support and to report this back to the controllers of the second actuating drives.
Vorteilhaft kann es auch sein, wenn die Schwenkbewegung der Trägerdrehachse mit einem elektronisch geregelten dritten Stellantrieb erzeugt wird, der einer von einer Steuereinrichtung vorgegebenen Bewegungskurve folgt.It can also be advantageous if the pivoting movement of the carrier axis of rotation is generated with an electronically controlled third actuator which follows a movement curve predetermined by a control device.
Die vorstehend genannten Ausgestaltungen beziehen sich zunächst einmal auf Bandwebmaschinen, beispielsweise mit einer Schussnadel. Auf breiteren Webmaschinen kann die erfindungsgemässe Technik vorteilhaft dadurch eingesetzt werden, dass als Schusseintragsmittel ein Greifer, ein pneumatisches Mittel oder - ganz konventionell - ein Schiffchen vorgesehen ist.The above-mentioned configurations initially relate to ribbon looms, for example with a weft needle. The technology according to the invention can advantageously be used on wider weaving machines in that a gripper, a pneumatic means or - quite conventionally - a shuttle is provided as the weft insertion means.

In einem zweiten Ausführungsbeispiel der vorliegenden Erfindung - bei dem die wesentlichen Elemente des ersten Ausführungsbeispiel übernommen wurden, soweit sie nicht unterschiedliche dargestellt sind - werden die Drehantriebe 16, 16a mittels elektronischer Regler 39, 39a derart geregelt, dass sie einer von einer Steuereinrichtung 41 vorgegebenen Bewegungskurve folgen. Weiterhin werden die Hubbewegungen der Lochnadelträger 14, 14a und/oder die Drehbewegung einer der mit ihnen verbundenen Wellen 30, 30a, 32, 32a und/oder die Drehbewegung der Drehantriebe 16, 16a mittels Sensoren gemessen und den Reglern 39, 39a den Drehantrieben 16, 16a zurückgemeldet.

Die Linearantriebe 18, 18a werden weiterhin mittels elektronischen Reglern 40, 40a derart geregelt, dass sie einer von einer Steuereinrichtung 41 vorgegebenen Bewegungskurve folgen.
