Definitions
- the invention relates to a guide element for a gripper conveyor element of a weaving machine, which has guides which form a positive, open to one side enclosure for the gripper transport element.
- gripper bars or gripper bands are provided, which are introduced from one side of the loom forth in a shed.
- a gripper transport member moves a gripper which has picked up a weft thread, either to the opposite side of the shed, where the weft thread is taken over by a transfer element.
- the gripper conveyor moves with the gripper and the weft yarn to about the middle of the shed, where it also accommodates a transfer gripper also transported by a gripper transport element, which picks up the inserted weft thread and then transports it out of the shed onto the other side of the shed ,
- the gripper conveyor moves with a gripper, a gripper grab, through the shed and picks up a weft, which is then pulled through the shed.
- the gripper conveyor elements are guided within the shed by means of guide elements which are attached to the sley. They carry out the weaving movement, whereby they penetrate from below into a warp sheet when the reed is moved from the edge of the fabric. They then move out of the shed through the lower warp thread and out again when the newly inserted weft thread is struck by the reed at the edge of the fabric.
- hook-shaped guide elements known (EP 02 75 479 B1 ) whose open side faces the reed. They serve in particular for guiding a gripper conveyor element designed as a rapier band. They have a guide associated with the upper side of the gripper transport element and an opposite guide assigned to the underside of the gripper transport element. Another guide is provided for a side surface of the gripper conveyor belt on the side facing away from the open side.
- the lower and / or upper guide engage in a longitudinal groove of the bottom and / or the top of the rapier, the sides of the guides, which are facing away from the open side, secure the gripper band against dodging towards the open side.
- These guides which are to avoid dodging of the rapier band toward the open side, are relatively small. As a result, considerable wear occurs on the guide elements and also on the gripper conveyor elements in a relatively short time.
- C-shaped guide elements which are also open to the reed.
- the gripper transport element which can also be a flexible rapier band here, is guided on the open side of the guide elements by means of two opposing sections of guides which prevent deflection in the horizontal direction towards the reed.
- the top and the bottom of the gripper transport element keep a distance to the opposite areas of the guide elements, so that they are not out.
- the gripper transporting member has a portion extending through the open side of the guide members, which is guided vertically between the opposite portions of the guides. In this type of construction, too, only guides with relatively small guide surfaces are present in particular in the direction of the reed, so that rapid wear is to be expected.
- the invention has for its object to provide guide elements of the type mentioned, which improve the guiding of the gripper conveyor elements.
- the guide element comprises a skirt which is provided with at least one projection associated with a longitudinal groove on the underside of the gripper transport element and on the open side with the projection having a shoulder whose upper edge forms a guide for the gripper trajectory which extends below the upper edge of the projection is located.
- the enclosure encloses the gripper transport element with guides, which are also assigned to the top and the bottom of the gripper transport element, resulting in relatively large guides without the dimensions must be increased. It is even possible to reduce the cross-sections of the gripper conveyor elements, without requiring the guides and guide surfaces must be reduced. Smaller cross-sections lead to lower masses and therefore allow higher weaving speeds, particularly advantageous is the projecting from the enclosure to the open side approach.
- this approach provides support for one outside the enclosure located part of the gripper transport element, so that it can be supported against torsional forces.
- the approach reduces the risk of trapping warp threads in the guide elements, which could result in damage to the warp yarns and / or warp yarn breaks.
- the approach is designed in the manner of a facing away from the border away tip. This tip can be inserted between two warp threads, which have already been pushed apart from the upper edge of the guide elements easily.
- the upper edge of the guide elements has a highest point, which is located in the area above the open side of the enclosure.
- the upper edge of the guide elements first strikes the warp sheet and pushes the warp threads slightly apart.
- the approach lies in the "shadow" of the top edge, so that it easily penetrates between the warp threads, which have already been pushed apart a bit.
- the risk that warp threads are caught is therefore significantly reduced.
- the risk is reduced that warp threads come into contact with the guides for the gripper transport element.
- guide elements are similar to that in the EP 0576854 A1 is shown attached to a sley, which also receives a reed.
- the sycamore performs swinging back and forth Movements to strike a weft thread to the edge of the goods.
- the guide elements are brought into a shed through the lower warp thread when the reed is in the rearmost position and a weft thread is entered.
- the batten moves with the reed towards the edge of the fabric, wherein the guide elements, after the gripper transport member has been withdrawn, again move out of the shed through the lower warp sheet.
- the reed is in the most backward position and in which a gripper transport element is inserted into a shed.
- the terms "up" and "down" are used, they refer to that position.
- FIG. 1 to 4 Guide element 10 shown has a fastening part 11, with which it is attached to a sley or an intermediate profile in a row one behind the other with the same Hughessetementen.
- the region 12 of the guide element Above the fastening part 11 is the region 12 of the guide element, which is intended to penetrate into a shed.
- the guide element has guides 14, 15, 16, 17 and 18, which form a gripper transport element 19 (FIG. 3 and 4 ) engage or enclose, so that the totality of the guides 14, 15, 16, 17, 18 is called a border for the gripper transport element 19.
- the enclosure 13 is on one side, ie on the side facing a reed, not shown, open.
- the guide 14 is assigned to the underside of the gripper transport element 19.
- the guide 15 guides the gripper transport element 19 on the side facing away from the open side, ie against movements from the open side.
- the guide 16 is assigned to the upper side of the gripper transport element 19 and prevents deflection of the gripper transport element 19 upwards.
- the guides 17 and 18 are side edges protrusions 40, 41 which protrude from the guide 16 assigned to the top or from the guide 14 associated with the underside and leave an open gap between them.
- the guide 18 extends substantially parallel to the guide 15.
- the guide 17 extends at an angle of about 45 ° to the guide 16.
- the upper, located in the region of the open side of the enclosure 13 edge of the gripper transport element 19 is formed correspondingly oblique.
- the gripper transport element 19 is advantageously guided in this way in all directions by the guide elements 10.
- the gripper transport element 19 has a widening 21 extending over at least part of its length (FIG. Fig. 4 ) with a length of eg 500 mm, which remains outside of the receptacle 13 and which serves to receive a gripper.
- the gripper transport element 19 may be a gripper belt that is relatively flexible about a horizontal axis, or a gripper bar that is relatively rigid about both a horizontal axis and a vertical axis.
- the broadening 21 may be integrally formed on the gripper transport element 19.
- a guide member is attached, which complements and / or replaces the gripper transport member 19 over part of its length and the widening 21 and carries the gripper.
- the projection 20 supports with its serving as a guide upper edge 43, the underside of the gripper conveyor element in the area of spreading 21, so that torsional forces can be absorbed.
- the guide element 10 has an overall approximately plate-like shape and is attached to a sley so that the flat sides are substantially parallel to warp threads.
- the area 12 of the guide elements 10 intended for penetration into a shed is machined so that it tapers in the direction of the open side as far as the projection 20, which forms a kind of point. From this slightly rounded tip of the lug 20 extends a side edge 22 in the manner of a groove to the fastening part 11, which is rounded.
- the side edge 22 is chamfered and merges into the flanks of the region 12. Due to the tapered shape, the guide 15 is relatively wide and in this embodiment has an almost constant width. In a modified embodiment, the guide 15 has an approximately trapezoidal shape.
- the guide 14 tapers towards the open sides and has an approximate trapezoidal shape.
- the projection 41 with the guide 18 has a rounded upper edge 42 and chamfered, upwardly tapering side surfaces, which merge into the flanks of the area 12.
- the region 12 has an upper edge 23 which is rounded. The adjoining the upper edge 23 surfaces are chamfered that they extend to the guides 16, 17 obliquely to the flanks of the region 12.
- the upper edge 23 has a highest point 24, which lies in the region of the open side of the receptacle This highest point 24 is the point at which the guide elements 10 first penetrate into a warp sheet while spreading apart the warp threads.
- the warp threads then slide on the inclined surfaces which adjoin the upper edge 23. They are already spread relatively far when the projection 41 and the projection 20 come into their area. Since the projection 20 is located below the upper edge 42 of the projection 41 and is preferably formed as a tip, it is between penetrate the already spread apart warp threads. Since the projection 41 tapers upwards and lies below the projection 40, it is covered by this. The projection 41 can therefore easily penetrate between already spread apart warp threads.
- the projection 20 and in particular its upper edge 43 are deeper than the projection 40, and the projection 20 can penetrate between already by the projection 41 and the projection 40 spread apart warp threads, without damaging them.
- the projection 20 is shielded by the projections 40 and 41, so that it does not catch warp threads which extend obliquely to the other warp threads. This ensures that no warp threads remain on the upper edge 43 of the projection 20, which could then be taken away by the gripper conveyor element and torn or damaged.
- a particularly good spreading apart of warp threads is obtained when the guide member 10 is made in the region of the guide 15 is relatively wide.
- FIGS. 5 and 6 correspond in principle to the embodiment according to Fig. 1 to 4 but with the guides facing each other in pairs and one pair each perpendicular to the other pair.
- the guides 14, 16 guide the gripper conveyor element 19 against dodging in the vertical direction.
- the guides 15, 18 and 27 are parallel to each other and prevent deflection of the gripper conveyor element 19 in the horizontal direction.
- the gripper transport element 19 of the Fig. 5 is provided with a widening 28 which is smaller in height than the height of the gripper transport element.
- the outer sides of the guides 18 and 27 forming sections serve as guides 45, 46, the corresponding surfaces of the widening 29 of the gripper conveyor element 19 are opposite. As a result, a good support against possibly acting in the region of the widening 29 torsional forces is achieved.
- the upper edge of the guide elements is designed so that in the region of the open side a highest point similar to the highest point 24 of the embodiment according to Fig. 1 to 4 has, with which the guide elements first penetrate into a warp sheet.
- the embodiment according to Fig. 7 to 10 corresponds in its basic structure of the embodiment according to Fig. 1 to 4 , so on the description for Fig. 1 to 4 Reference is made and the same reference numerals are used.
- a projection 30 projects into the receptacle 13. This projection 30 forms additional side guides, which prevent deflection of the gripper transport element in the horizontal direction and in particular toward the open side. The enlargement of the guides serves to reduce the Verscht filedes.
- the upper edge 43 of the projection 20 is offset relative to the guide 14 down. This further reduces the risk of warps with the top edge 43 of the neck 20 coming into contact, since the warp threads are spread apart by the projection 41 and the adjoining side surfaces of the guide element. The risk of damaging the warp threads is the smaller, the greater the distance between the upper edge 42 of the projection 41 and the upper edge 43 of the projection 20 is.
- the embodiment according to Fig. 12 differs from the embodiment according to Fig. 11 in that a projection 30 is provided which protrudes from the guide 14 and engages in a longitudinal groove of the gripper transport element 9.
- 19 is provided between the upper edge 42 of the projection 41 and the groove bottom of the longitudinal groove of the gripper transport element 19, a clearance or a game. This avoids that the relatively narrow upper edge in the areas of the groove bottom of the longitudinal groove of the gripper transport element generates increased wear.
- the embodiment Fig. 13 is also provided between the bottom 44 of the projection 40 of the guide member 10 and the groove bottom of a longitudinal groove of the gripper transport element 19, a distance or a game.
- the gripper conveyor element 19 after Fig. 14 has a flat, rectangular cross section and is particularly suitable for use as a rapier band which can be guided around a drive wheel of a rapier loom by means of a guide block.
- the gripper conveyor element 19 is guided by means of guide elements 80, the guide 81 for the smooth, not through a groove or the like. have profiled top of the gripper transport element 19.
- the guide of the guide element 80 assigned to the underside of the gripper transport element is provided with a projection 41 which engages in a longitudinal groove of the gripper transport element 19.
- a projection 20 is provided, whose upper edge is lower than the upper edge the projection 41 is located and thus shielded in the manner already described upon penetration into a warp thread.
- the embodiment according to Fig. 15 differs from the embodiment according to Fig. 14 in that a second projection 30 protrudes from the guide 88 assigned to the underside of the gripper transport element 19.
- the longitudinal grooves of the gripper transport element 19 and the projections 30, 41 are coordinated so that between the upper edges of the projections 30, 41 and the groove bottom of the longitudinal grooves of the gripper transport element 19 a game is present.
- the upper edge 43 of the projection 20 does not have as in the embodiment according to Fig. 14 or 15 lower than the guide 88 lie. It is essential, however, that the upper edge 43 of the projection 20 is arranged lower than the upper edge 42 of the projection 41st
- the projection 41 is held relatively wide in the direction of the width of the gripper transport element 19.
- the guide member 80 forms only with the upper edge of the projection 41 and the upper edge 43 of the projection 20 guides that prevent dodging of the gripper conveyor element in the downward direction.
- associated guide 84 is left a game.
- Fig. 18 is a modified embodiment of Fig. 17 shown, in which the upper side of the gripper conveyor element 19 is provided with a longitudinal groove, in which a projection 41 opposite projection 86 of the guide member 80 engages.
- Gripper transport element 19 is in the vertical direction only from the upper edge of the projection 41 and the lower edge of the projection 86 out. Subsequent to the guide 87, a play 85 is provided between the upper side of the gripper transport element and the guide element 80.
- FIGS. 14 to 18 The leadership forms after FIGS. 14 to 18 are particularly well suited to absorb torsional forces that can be introduced into the gripper transport element 19 due to the arrangement of a gripper, not shown, in particular during acceleration and deceleration.
- the projection 20 from the open side of the guide elements 10 or 80 away not designed as a tapered tip, but is provided with parallel surfaces. This configuration is particularly possible if the guide elements 10, 80 in the region of the guides 15, 87 are relatively wide and therefore warp threads are spread accordingly wide when the upper edge 43 of the projection 20 passes in the region of the warp threads.
- the invention is not limited to the illustrated embodiments. In particular, it is possible to realize the features described for the individual embodiments in other embodiments. For example, it is also possible according to the embodiment Fig. 5 or 6 to provide a projection corresponding to the projection 30.

Abstract
Description
Die Erfindung betrifft ein Führungselement für ein Greifertransportelement einer Webmaschine, das Führungen besitzt, die eine formschlüssige, nach einer Seite offene Einfassung für das Greifertransportelement bilden.The invention relates to a guide element for a gripper conveyor element of a weaving machine, which has guides which form a positive, open to one side enclosure for the gripper transport element.
Als Greifertransportelemente werden Greiferstangen oder Greiferbänder vorgesehen, die von einer Seite der Webmaschine her in ein Webfach eingeführt werden. Ein Greifertransportelement bewegt einen Greifer, der einen Schussfaden aufgenommen hat, entweder bis zur gegenüberliegenden Seite des Webfaches, wo der Schussfaden von einem Übernahmeelement übernommen wird. Oder das Greifertransportelement bewegt sich mit dem Greifer und dem Schussfaden bis etwa zur Mitte des Webfaches, wo ihm ein ebenfalls von einem Greifertransportelement transportierter Übernahmegreifer entgegenkommt, der den eingetragenen Schussfaden übernimmt und dann bei der Bewegung aus dem Webfach heraus auf die andere Seite des Webfaches transportiert. Oder das Greifertransportelement bewegt sich mit einem Greifer, einem Nehmergreifer, durch das Webfach und holt einen Schussfaden ab, der dann durch das Webfach gezogen wird. Die Greifertransportelemente werden innerhalb des Webfaches mittels Führungselementen geführt, die an der Weblade befestigt sind. Sie führen die Webladenbewegung mit aus, wobei sie von unten in eine Kettfadenschar eindringen, wenn das Webblatt von dem Warenrand hinweg bewegt wird. Sie bewegen sich dann wieder aus dem Webfach durch die untere Kettfadenschar hindurch hinaus, wenn der neu eingetragene Schussfaden von dem Webblatt an dem Warenrand angeschlagen wird.As gripper conveyor elements gripper bars or gripper bands are provided, which are introduced from one side of the loom forth in a shed. A gripper transport member moves a gripper which has picked up a weft thread, either to the opposite side of the shed, where the weft thread is taken over by a transfer element. Or the gripper conveyor moves with the gripper and the weft yarn to about the middle of the shed, where it also accommodates a transfer gripper also transported by a gripper transport element, which picks up the inserted weft thread and then transports it out of the shed onto the other side of the shed , Or the gripper conveyor moves with a gripper, a gripper grab, through the shed and picks up a weft, which is then pulled through the shed. The gripper conveyor elements are guided within the shed by means of guide elements which are attached to the sley. They carry out the weaving movement, whereby they penetrate from below into a warp sheet when the reed is moved from the edge of the fabric. They then move out of the shed through the lower warp thread and out again when the newly inserted weft thread is struck by the reed at the edge of the fabric.

Es sind weiter Führungen bekannt (
Der Erfindung liegt die Aufgabe zugrunde, Führungselemente der eingangs genannten Art zu schaffen, die das Führen der Greifertransportelemente verbessern.The invention has for its object to provide guide elements of the type mentioned, which improve the guiding of the gripper conveyor elements.
Diese Aufgabe wird gelöst durch ein Führungselement mit den Merkmalen des Anspruchs 1.This object is achieved by a guide element having the features of claim 1.
In einer Ausgestaltung umfasst das Führungselement eine Einfassung, die mit wenigstens einem einer Längsnut der Unterseite des Greifertransportelementes zugeordneten Vorsprung und auf der offenen Seite anschließend an den Vorsprung mit einem Ansatz versehen ist, dessen Oberkante eine Führung für das Greifertraiispoileiemeiit bildet, die sich unterhalb der Oberkante des Vorsprungs befindet.In one embodiment, the guide element comprises a skirt which is provided with at least one projection associated with a longitudinal groove on the underside of the gripper transport element and on the open side with the projection having a shoulder whose upper edge forms a guide for the gripper trajectory which extends below the upper edge of the projection is located.
Da die Einfassung das Greifertransportelement mit Führungen umschließt, die auch der Oberseite und der Unterseite des Greifertransportelementes zugeordnet sind, ergeben sich relativ große Führungen, ohne dass die Abmessungen erhöht werden müssen. Es ist sogar möglich, die Querschnitte der Greifertransportelemente zu verkleinern, ohne dass hierzu die Führungen und Führungsflächen verkleinert werden müssen. Kleinere Querschnitte führen zu geringeren Massen und erlauben deshalb höhere Webgeschwindigkeiten, insbesondere von Vorteil ist der von der Einfassung zur offenen Seite hin ragende Ansatz. Dieser Ansatz bildet einerseits eine Unterstützung für einen außerhalb der Einfassung befindlichen Teil des Greifertransportelementes, so dass dieses gegen Torsionskräfte abgestützt werden kann. Darüber hinaus verringert der Ansatz die Gefahr, dass Kettfäden in den Führungselementen gefangen werden, was zu Beschädigungen der Kettfäden und/oder Kettfadenbrüchen führen könnte.Since the enclosure encloses the gripper transport element with guides, which are also assigned to the top and the bottom of the gripper transport element, resulting in relatively large guides without the dimensions must be increased. It is even possible to reduce the cross-sections of the gripper conveyor elements, without requiring the guides and guide surfaces must be reduced. Smaller cross-sections lead to lower masses and therefore allow higher weaving speeds, particularly advantageous is the projecting from the enclosure to the open side approach. On the one hand, this approach provides support for one outside the enclosure located part of the gripper transport element, so that it can be supported against torsional forces. In addition, the approach reduces the risk of trapping warp threads in the guide elements, which could result in damage to the warp yarns and / or warp yarn breaks.
In zweckmäßiger Ausgestaltung der Erfindung wird vorgesehen, dass der Ansatz in der Art einer von der Einfassung hinweg gerichteten Spitze gestaltet ist. Diese Spitze lässt sich zwischen zwei Kettfäden einführen, die bereits von der Oberkante der Führungselemente leicht auseinandergeschoben worden sind.In an advantageous embodiment of the invention it is provided that the approach is designed in the manner of a facing away from the border away tip. This tip can be inserted between two warp threads, which have already been pushed apart from the upper edge of the guide elements easily.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass die Oberkante der Führungselemente einen höchsten Punkt aufweist, der sich in dem Bereich oberhalb der offenen Seite der Einfassung befindet. Die Oberkante der Führungselemente trifft zuerst auf die Kettfadenschar auf und drückt die Kettfäden etwas auseinander. Der Ansatz liegt im "Schatten" der Oberkante, so dass er leicht zwischen die Kettfäden eindringt, die bereits etwas auseinandergeschoben worden sind. Die Gefahr, dass Kettfäden gefangen werden, ist deshalb wesentlich verringert. Ebenso ist die Gefahr verringert, dass Kettfäden mit den Führungen für das Greifertransportelement in Kontakt kommen.In a further embodiment of the invention it is provided that the upper edge of the guide elements has a highest point, which is located in the area above the open side of the enclosure. The upper edge of the guide elements first strikes the warp sheet and pushes the warp threads slightly apart. The approach lies in the "shadow" of the top edge, so that it easily penetrates between the warp threads, which have already been pushed apart a bit. The risk that warp threads are caught is therefore significantly reduced. Likewise, the risk is reduced that warp threads come into contact with the guides for the gripper transport element.
