Definitions
- the invention relates to a thread holding device according to the The preamble of claim 1 and a series shed loom with Thread holding device.
- a thread holding device is described in CH-A-550 874.
- the Device contains holding elements which are arranged so that they are partially cover so the end of a weft around this can be put around and insertion elements between the Holding elements are arranged horizontally and can be moved relative to them the weft in a direction transverse to the weft in the To slide holding elements and in the direction of its longitudinal extension hold.
- Disadvantages of the known thread holding devices are that the detection, Holding and guiding threads only imprecisely and with a low repetition rate is reproducible.
- Another disadvantage is that the threads when moving in the known holding devices along curves align that are strongly curved in relation to the guide direction, and malfunctions such as loop and ball formation or one Cause thread backlog in the holding device.
- the disadvantages mentioned have a particular impact on row shed looms where one Variety of weft threads processed sequentially at a high rate Need to become.
- Such a weaving machine is e.g. known from EP-A-582 763. Under this The condition for series shed weaving machines is the production set limits by particularly fine, homogeneous fabrics, when the highest machine performance is sought.
- the invention seeks to remedy this.
- the invention as characterized in claim 1, solves the Task to create a thread holding device with which threads in the guide direction as little as possible be curved and with which a sequential Holding threads in short intervals, d. H. With a large repetition rate is possible.
- Claims 2-11 relate to advantageous ones Embodiments of the invention Thread holding device.
- the claim 13 relates to a Row shed weaving machine with an inventive Thread holding device.
- the device according to the invention has the advantage that the thread in its longitudinal direction with a frictional force is held, which is much greater than the frictional force in the guiding direction across the thread; the transport of the held thread in the guide direction is therefore almost frictionless. It is advantageously compact, which makes it possible to hold the thread when Support transportation through the device so that it always stays stretched and does not form loops. Furthermore, the frictional force can be precisely controlled and can be quickly adapted to changing requirements become. Appropriate management of the Relative movement between holding arrangements and Insertion elements that have multiple threads at the same time several insertion elements for threading into the Holding device prepared and advantageously in faster sequence can be threaded.
- the thread holding device according to the invention can with Be adapted to the specifics of a benefit Row shed weaving machine using each weft channel of the Weaving rotor of the machine on the weft and / or catch side several insertion elements are assigned, the Insertion elements fixed with respect to the weaving rotor are arranged.
- the holding elements are fixed in place so that the insertion elements at rotating weaving rotor the desired relative movement perform with respect to the holding elements to him Feed holding elements.
- Advantages of this Embodiment of the invention Thread holding device can be seen in that the Insertion elements through their shape and their Positioning relative to the weft channels of the weaving rotor can be designed so that the insertion elements like one Extend a firing channel.
- the insertion elements through-holes have the shape of the profiles of the firing channels are adjusted. Interference on weft threads at the end of a firing channel are reduced and the Reproducibility of weft insertion improved. Further can the shape of the insertion elements and the arrangement of the Holding elements in such a way to the weaving rotor and to the Alignment of those controlled with the help of the web rotor Looms are customized to match the sections of the Weft thread emerging from a weft channel laterally stick out, be moved in the same way as that Weft sections in the weft channel. Through this uniform treatment of the entire weft thread and the improved reproducibility of the weft insertion the requirement created for weaving especially homogeneous fabrics with row shed weaving machines, the Homogeneity of the fabric, especially in the edge area is guaranteed.
- the invention is based on a series shed weaving machine explained, the task being solved as an example, Weft threads that are in the weft channels of the weaving rotor Weaving machine are registered on one of the protruding end of a firing channel To capture, hold and move section, by the section according to the invention with insertion elements fed to a holding device and along a Tangential plane of the web rotor is moved accordingly the path of a weft on the way to the goods edge an already manufactured fabric. This situation can be transferred analogously to the shot side Relationships.
- the weaving rotor 1 shows a weaving rotor 1 Row shed weaving machine with a preferred one Embodiment of an inventive Holding device.
- the weaving rotor 1 has one cylindrical body 2 which is about an axis 3 in Direction of arrow A rotates.
- the web rotor 1 is with a plurality of shot channels 5 (5a, 5b, 5c, ...) provided, which are distributed at equal intervals and by rows of on the circumference of the body 2 attached thread guide elements 6 are formed.
- stop elements 83 (see FIG. 4) provided that each in the direction of rotation of the rotor Thread guide elements 6 are arranged downstream.
- the Holding device is on the catch side at a distance from the last thread guide element 6 arranged to one weft thread 20 inserted into a weft channel hold.
- a suction nozzle 50 is provided which the holding device downstream in the entry direction of the weft thread 20 and the weft in the direction of 51 drawn in air stretches.
- FIG. 1 To establish a geometric relationship between FIG. 1 and the other figures are the x, y, z axes of a coordinate system, with the z-axis in the direction of the axis of rotation 3 of the weaving rotor 1.
- the holding device comprises two holding arrangements 40 for Holding a thread and three as annular disks 12, hereinafter called insertion element rings, in which the Insertion elements that thread the thread into the holding arrangement 40 introduce, are integrated.
- the insertion element rings 12 are parallel and spaced apart as well connected to the weaving rotor 1.
- the holding arrangement 40 for Holding the thread from two lamellar elements 41, 42, which are attached at one end, such that the free end of the elements 41, 42 between two disks 12 protrudes in the edge area.
- the elements 41, 42 are arranged so that Sections of elements 41, 42 overlap and form a gap 44 (see FIG. 6) in which the Thread is insertable.
- the edges 45, 46 of the overlapping Sections are rounded and form sliding surfaces.
- To the free ends of the holding elements 41, 42 Guide surfaces 55, 56 formed one Determine threading point 48.
- the Insertion element ring 12 recesses 59 formed, the number of which corresponds to the number of firing channels or in other words, each shot channel is a recess 59 assigned.
- This recess is the essential Feature of an 'insertion element', in this Connection under insertion element a section 12A of the Introducer ring is understood due to its shape with a relative movement to the Holding arrangement 40 a weft thread in the holding arrangement 40 introduces and moves.
- the recess 59 includes one first section 60 and a second section 61 with a slot 62 which opens into the first section 60.
- the introducer ring 12 has four lugs 91A that extend from the inner circumference are directed inward.
- the thread guide elements 6 have an opening 32 which defines the firing channel 5 determine and a slot 33 on to a weft to let out of the thread guide elements.
- the stop elements 83 are as free-standing slats trained and have a in the region of the free end specially trained edge 84 to a weft to advance and on a fabric edge (not shown) ultimately striking.
- FIG. 4 serves to explain criteria according to which the shape of each shot channel assigned Insertion elements is optimized.
- FIG. 4 shows viewed in the direction of the axis of rotation 3 of the weaving rotor 1, one Section of a cross section through the weaving rotor 1, wherein the cross section the section I-I in FIG. 1.
- the selected section of the weaving rotor 1 is on its Outside with 2 rows of thread guide elements 6 and two Rows of stop elements 83, each arranged in parallel to the axis of rotation 3 in grooves 90, 91.
- the groove 91 also serves as a guide for the guide tooth 91A of the Introducer ring 12.
- the contour of the Insertion element ring 12 is adapted in sections the shape of the thread guide elements 6 and Stop elements 83: the bullet opening 61 and the Exit slot 62 correspond in shape to the opening 32 and the slot 33. So for one Weft thread when inserting weft on the insertion elements 12A practically identical aerodynamic conditions as in the weft channels and the weft insertion is because of the improved air flow in the through openings 61 less susceptible to faults due to disturbing winds at the ends the shot channels 5.
- the edge is a Insertion element that feeds the weft causes, in the following called feed edge, adjusted to the contact surfaces on which the weft thread runs lengthways of the weaving rotor rests or slides: the feed of a weft causing edges 65 and 63 of the Insertion element rings 11 have the same contours as the corresponding edges 34, 84 of the Thread guide elements 6 or the stop elements 83.
- This adaptation of the shape of the insertion elements results in that a weft at the location of the insertion elements 12A so is moved like the sections of the thread in the weft channel, namely, that the thread including that of the Insertion elements entrained sections in one only radial plane rotating with the weaving rotor through the axis of rotation 3 of the weaving rotor 1.
- This Shape adjustments help ensure that the individual Weft threads are as reproducible and stretched as possible Form to be applied to the fabric edge, so that a the most homogeneous tissue possible.
- FIG. 6 shows the holding effect of the holding elements 41, 42 pierce the holding elements, overlapping, each with a sliding edge 45 or 46, the weft direction 25 of the weft thread 20, so that the by means of the suction nozzle 50 biased thread 20 meandering through the Slot 44 must wind around the sliding edges 45 and 46.
- the holding effect of this arrangement is based on two Mechanisms: The meandering nestling of the pre-tensioned thread causes looping friction in Longitudinal direction of the thread; through a sufficiently tight Distance between the sliding edges 45 and 46 can in addition, a clamping force can be generated on the thread. Both mechanisms create a frictional force, one Counteracts tensile force on the thread.
- To the number of holding arrangements 40 and insertion elements 12A per firing channel arbitrarily increased become.
- FIG. 5 shows the threading of the weft thread 20 into the Holding arrangement 40 by two insertion elements 12A, the are each assigned to a firing channel and on both sides be moved past the holding arrangement. Both Insertion elements are positioned so that they are in considered z direction, overlap. Still going out FIG. 5, as with the insertion elements 12A of the Weft thread 20 between the holding elements 41 and 42 pushed and guided along the sliding surfaces 45 and 46 becomes. The insertion member 12A rotates around the center of the axis of rotation 3 in the direction A. The weft thread 20 lies between the insertion Holding elements 40 and 41 at the edge 65 of the penetration opening 61.
- the holding elements 40 and 41 are positioned that the weft 20 from the edge 65 against one of the Leading edges 55 or 56 and with further movement of the Insertion element 12A at the threading point 48 between the Holding elements 41, 42 pushed, the leading edges 55 or 56 when feeding the thread in the direction of the Sliding surfaces 45, 46 continuously the meandering Course of the weft thread according to FIG. Force 6.
- the weft thread 20 is formed by the edges 45, 55, 46, 56 positively guided. These edges are oriented so that they usually not tangent to the direction of movement of the insertion member 12A. Accordingly, the Thread a relative movement with respect to the insertion element 12A from: According to FIG. 5 the thread moves away from Center of rotation 3 along the edge 65 to finally at a certain position of the insertion member 12A Bullet opening 61 through the outlet slot 62 leave. At this moment the thread 20 is in the angular position B.
- the Weft 20 as long as no thrust along the Sliding surfaces 45 and 46 transfer like the thread 20 itself in the area of the edge 64 of the insertion element 12A is:
- the edge 64 is a circular arc element around the Center of rotation axis 3 is executed and is therefore always tangent to the direction of movement of the Introducer 12A.
- the weft thus remains as long still between the holding elements 45 and 46 until he is reached by the edge 63 which pushes it on, as long as it moves to the angular position C.
- the Angular position C of edge 63 corresponds to position 21 of the thread in the holding arrangement 40, where the thread without to have contact with the insertion elements 12A, remains lying.
- the spatial course determines of the edges 65, 64, 63 the time course of the Forced movement of the weft thread along the sliding surfaces 45 and 46, the monotonous rotation of the Insertion element a non-monotonous movement of the thread is implemented.
- the timing of the movement of the Weft thread is that the edges of the holding elements 41 and 42, which guide the weft, are not tangential lie for moving the sections of the insertion element 12A that push the weft 20.
- the insertion element rings 12 are suitable for to be pushed a weaver rotor.
- the lugs 91A are on to facilitate displacement the inside of the ring in FIG. 3 provided. This have the function of guiding teeth that corresponding grooves 91 on the outside of a weaving rotor are adapted (FIG. 4).
- the movability of the Insertion elements along the axis of rotation of the weaving rotor facilitates the change of the weaving width of the Row shed weaving machine. To change the weaving width only need thread guide elements 6 and Stop elements 83 removed on the weaving rotor and Insertion element rings 12 are moved without the Length of the web rotor itself must be changed. Furthermore, holding elements must also be used for this purpose according to FIG. 1 postponed, which is due to it Compactness is not a problem.
- a thread holding arrangement according to FIG. 2 has due to Dimensions of the holding elements 41, 42 compared to A precisely defined diameter of a weft thread and controlled positionable threading point 48. It is also possible, by precise displacement or Tilting of the holding elements 41, 42 the Frictional resistances of the thread holding arrangement are suitable change and along the sliding surfaces 45, 46 (i.e. in the y direction in Figure 2) as a function of the position of the To vary the thread. That is z. B. reached by changing the overlap of the holding members for the purpose Change in belt friction.
- FIG. 7 gives an example of how good controllability the threading points of the holding elements can be used can be particularly gentle on the weft side and weft threads to feed thread holding devices by the when entering the thread holding devices occurring changes in the thread tension as possible be evenly distributed over the entire length of the thread.
- FIG. 2 shows several holding arrangements 40 type on the weft side and on the catch side graded one at a time that the shot-side holding arrangements the catch side Holding arrangements, based on the direction of rotation of the Web rotor or one in a shot channel entered and moved in the direction of rotation Weft thread, upstream: This is how the thread from the shot-side holding arrangements only in its Longitudinal direction before going from the catch side Holding arrangements is detected.
- the threading points 48A-C are on the weft side, the threading points are 48D-F arranged on the catch side.
- the device for holding a thread comprises at least one holding arrangement 40 consisting of two itself overlapping holding elements 41, 42 for the thread 20 and at least two insertion elements 12 which are relative to the Holding elements are moved to a cross to Direction of movement of the insertion elements and across the Holding elements running thread 20 between the To slide holding elements, with the thread in its Is held in the longitudinal direction and across it, along the Holding elements 41, 42 is moved.
- the thread is in his Preloaded in the longitudinal direction.

Description
- Bei der erfindungsgemässen Vorrichtung wird der Faden in der Richtung, in der er durch die Halteelemente gehalten und geführt wird, von mehreren Einführelementen relativ zu den Halteelementen verschoben. Dabei sind die Halteelemente und Einführelemente relativ zu einander so positioniert, dass sich ein Fadenabschnitt, der mit einem Halteelement in Berührung ist, zwischen Fadenabschnitten befindet, die mit Einführelementen in Berührung sind. Dadurch wird vorteilhaft erreicht, dass der Faden in der Richtung, in der er durch die Halteelemente gehalten und geführt wird, nicht bzw. nicht wesentlich gekrümmt wird, und zwar um so weniger, je geringer der Abstand zwischen den Einführelementen ist und je geringer die Ausdehnung der Halteelemente in Richtung der Längserstreckung des Fadens ist. Die Gefahr, dass sich ein Fadenrückstau in der Fadenhaltevorrichtung bildet, kann so minimiert werden.
- Die Forderung nach einem geringen Raumbedarf der Halteelemente in Richtung der Längserstreckung des Fadens kann dadurch besonders vorteilhaft erfüllt werden, dass der Faden an ein oder mehreren Stellen jeweils zwischen zwei Lamellen gehalten wird, die sich längs einer ihrer Kanten abschnittsweise überlappen, so dass sich der Faden meanderartig um die Kanten windet. Diese Anordnung gewährleistet die Anisotropie und die Kontrollierbarkeit der Reibungskräfte.
- Eine sequentielle Verarbeitung von Fäden mit der insbesondere bei Reihenfachwebmaschinen auftretenden hohen Repetitionsrate ermöglicht die erfindungsgemässe Vorrichtung dadurch, dass die Einführelemente auf einer Bahn bewegt werden, die abschnittsweise nicht mit der Richtung übereinstimmt, in der die Fäden von der Haltevorrichtung geführt werden. Daraus resultiert, dass ein von einem Einführelement transportierter Faden eine Zwangsbewegung relativ zum Einführelement ausübt und letztlich von diesem abgleitet, ohne im folgenden mit dem Einführelement in Berührung zu sein. Ferner trennt sich das Einführelement, ohne Bewegungsumkehr, auf seiner Bahn räumlich von der Haltevorrichtung und gibt die Haltevorrichtung derart frei, dass der nächste Faden von einem anderen Einführelement der Haltevorrichtung zugeführt werden kann. Die gewünschte hohe Repetitionsrate der Fadenverarbeitung wird somit dadurch erzielbar, dass eine Vielzahl von Einführelementen auf geschlossenen Bahnen in Umlauf gebracht werden und, zyklisch wiederkehrend, nacheinander jeweils einen Schussfaden in die Haltevorrichtung einführen.
