Definitions

the present invention relates to a heald frame for weaving looms with sidepiece/crossbar coupling joints with improved performances.
the invention relates to a heald frame for high-speed weaving looms, specifically air looms.
heald frames are devices used in weaving looms where - through their alternate movement, controlled by a weaving machine, along a plane perpendicular to the weaving plane - they control the movement of groups of warp threads in order to form the shed wherein a weft thread is synchronically inserted.
the heald frames are two and the warp threads are alternately linked to one or the other of said frames.
there are more heald frames e.g., up to the number of 24 heald frames, each one operating on a smaller number of warp threads in order to create more complex patterns by using warp threads and weft threads of different quality or colour.
the heald frames slide within suitable lateral guides, in a direction perpendicular to the fabric plane, between an upper and a lower position with reference to said plane, and they are controlled in this movement by actuating tie rods hooked to the heald frame.
a weaving machine imparts the movement to said tie rods in a known manner, in order to form a desired and predetermined fabric pattern.
Each heald frame consists of two crossbars - on which thin rods of steel or other materials (the "healds" indeed) are inserted with a certain play and which are provided with a central eyelet through which one or more warp threads run - and two sidepieces; these latter are the elements which cooperate with the above mentioned side guides in order to determine a regular alternating movement of the heald frame.
sidepieces and crossbars are mutually fixed, at the four corners of the heald frame, by suitable coupling joints.
the structure of the sidepiece/crossbar coupling joints must allow for a rigid coupling between these elements, so as to avoid as much as possible any deformation of the frame during the very fast alternating movements to which the frame is subjected while the loom is working.
this coupling must also be easily and quickly removable, as to allow a lateral opening of the frame and insertion or removal onto/from the crossbars of a desired number of healds for each individual weaving operation.
this mechanical coupling provides for a single screw means which locks in position a tenon, projecting from the sidepiece and integral therewith, within a corresponding cavity formed in the end portion of the crossbar.
Mechanical couplings of this type between the crossbars and the sidepieces of a heald frame are for example disclosed in EP-0513281 , EP-1646742 , EP-2009158 , and EP-2653594 .
an additional intermediate element is provided, which element is housed in the cavity of the crossbar and cooperates with said tenon, in order to improve the mutual fixing between the tenon and the crossbar, to facilitate its disengagement and/or to ensure a better stress distribution.
Mechanical couplings of this type between a heald frame crossbar and sidepiece are, for example, disclosed in EP328953 , EP-1526198 and EP-3191633 .
EP 328953 discloses an intermediate element of this type which comprises an oscillating arm and is therefore considered as a prior art closest to the present invention, the main claim of which therefore comprises, in its preamble, the features disclosed by this document.
the technical problem underlying the present invention is therefore that of providing a heald frame equipped with sidepiece/crossbar coupling joints with improved performances, i.e. wherein the peak value of the stresses concentrated at the sidepiece/crossbar coupling zones is substantially reduced, thus considerably lengthening the onset times of fatigue failures and therefore the service life of the heald frames.
this objective must be achieved while maintaining unchanged the positive performances of the known type coupling joints, such as the geometric rigidity of the heald frame and the easy and quick opening and closing of the joint.
a first object of the present invention is to extend the contact areas between the opposite elements of a crossbar and a sidepiece, so as to achieve stress distribution on a wider surface, and thus reduce its maximum value per unit area.
Another object of the invention is then to manufacture the sidepiece/crossbar coupling joints so that they provide a predefined tightening position wherein a slight degree of coupling elasticity is provided, of such a low amount as not to alter the overall rigidity of the heald frame, with regard to the weaving point of view, but nevertheless sufficient to considerably reduce the peak values of concentrated stresses which occur, especially, in the inversion steps of the heald frame alternate motion, wherein said heald frames are in fact subjected to the highest stresses.
a further object of the invention is to provide a coupling joint closing device which allows for a simplified opening of the coupling joint once the single screw-type fastener has been loosened, thus making easier and faster the engagement and disengagement of the sidepiece into/ from the crossbars.
heald frame for weaving looms having the features defined in the claim 1.
Other preferred features of said heald frame are defined in the secondary claims.
a sidepiece/crossbar coupling joint of the more elaborate type described above is used (disclosed, for example, in EP-328953 ), wherein the intermediate element which allows the coupling between the sidepiece and the crossbar comprises an oscillating arm.
the oscillating arm has a wedge end which engages two opposite inclined surfaces formed on the sidepiece tenon when the coupling joint is tightened. In this way, a predetermined mutual coupling position between the sidepiece and the crossbar is provided, which position is completely independent of the direct contact between the sidepiece and the side end of the crossbar, as is normally the case with prior art joints.
the oscillating arm is directly hinged to the crossbar body, so that the position of its wedge end is perfectly stable over time and does not depend on the assembly position of the intermediate element or on any possible elastic strain, under stress, of this element.
the heald frame sidepiece F is provided with a flat tenon 1 at both its ends (of which only one is shown in the drawings), laterally projecting towards a housing cavity C provided in the end portion of the crossbar T, thus following a general configuration of a sidepiece/crossbar coupling joint already widely known in the art.
the sidepiece F is made of a light metal material, for example aluminium alloy or other light alloys.
the tenon 1 has a level internal edge 1i and an opposite outer edge 1e provided with a V-shaped notch, thus forming two oppositely inclined engaging surfaces.
internal edge of the tenon refers to the tenon 1 edge which faces the centre line of the sidepiece F
outer edge refers to the one facing in the opposite direction, i.e. facing the ends of the sidepiece F.
a flat intermediate element is then provided, housed inside the cavity C of the crossbar T and intended to cooperate with the tenon 1 in order to carry out the tightening of the sidepiece/crossbar coupling joint.
Such intermediate element comprises a support body 2 and an oscillating arm 4, which is free to rotate for a limited arc of a circle.
the free end of the arm 4 is shaped as a wedge 5 which - following said rotation of the arm 4 for a limited arc of a circle, caused by the control end of a screw V operating on the free end of the oscillating arm 4 - moves between a disengagement position, wherein the two tenons 1 of a sidepiece F can be freely inserted and removed from the corresponding cavities C, to an engagement position, wherein said tenons 1 are rigidly locked within said intermediate element.
said locking position the wedge 5 and the V-shaped notch provided on the outer edge 1e of the tenon 1 are mutually matched, the two opposite operating surfaces of the wedge 5 resting on two corresponding oppositely inclined engagement surfaces of the V-shaped notch provided on the outer edge 1e of the tenon 1.
the opposite base end 4c of the oscillating arm 4 is provided with a partly circular outline and is housed with play in a corresponding partial circular seat 2c formed in the support body 2.
partial circular seat a seat which extends around the base end 4c for more than 180°, preferably at least 210°, is intended.
a circular hole is further provided, coaxial with said circular outline, in which a bush 6 is housed.
the bush 6 is in turn hinged on a pin 3 which is fixed onto the walls of the crossbar T . Therefore, pin 3 acts as a hinge of the bush 6 and consequently of the oscillating arm 4, which is thus directly constrained in a fixed position to the crossbar T.
the coupling between the base end 4c of the oscillating arm 4 and the respective circular partial seat 2c is useful to facilitate and speed up the correct assembly of the intermediate body 2 inside the cavity C, which cavity is accessible only by its opening at the side portion of the crossbar T.
this coupling allows to keep the support body 2 and the oscillating arm 4 mutually joined during the insertion of these elements inside the cavity C, while the support body 2 is guided by its lower level portion sliding on the bottom surface Cf of the cavity C and by its thin upper elastic portion sliding on the opposite top surface of cavity C.
the bush 6 is found in correspondence with a respective hole provided on the crosspiece T where the pin 3 can be inserted and locked, which pin 3 therefore exactly defines the working position of the oscillating arm 4 with respect to the crossbar T.
the support body 2 and the bush 6 are moulded in a suitable thermoplastic material, such as for example polyoxymethylene, polyamide or polyester, while the oscillating arm 4 is made of a more rigid material, such as for example steel; furthermore, the inclined operating surfaces of the wedge end 5 of the oscillating arm 4 are provided with a thermoplastic material covering 8, in the area meant to engage with the opposite surfaces of the V-shaped notch formed on the outer edge 1e of the tenon 1.
An extended element 9 of a similar thermoplastic material is also fastened to the sidepiece F surfaces meant to contact the crossbar T side portion, when the sidepiece/crossbar coupling joint is tightened.
the tightening of the coupling joint is achieved by screwing the screw V, by means of a suitable torque controlled wrench, until the wedge end 5 is thrust into mutual engagement with the V-shaped notch formed in the tenon 1, so locking the tenon 1 into its seat formed between the support body 2 and the oscillating arm 4, thus making integral the sidepiece F and the crossbar T in a predefined mutual position.
the mutual engagement between the opposite inclined surfaces of the wedge end 5 and the corresponding surfaces of the V-shaped notch formed on the tenon 1, automatically determines the desired positioning of the sidepiece F with respect to the crossbar T - independently of the contact between the sidepiece F and the side end of the crossbar T - also thanks to the fact that the lower edge 1i of the tenon 1 can freely shift on the corresponding bearing surface 2s, likewise level, of the support body 2, in the steps of coupling and tightening of the sidepiece/crossbar coupling joint, up to the desired final coupling position, wherein the front edge 1f of the tenon 1 approaches an abutment surface 2r of the support body 2 without however contacting the same.
thermoplastic material 9 By varying the length of the oscillating arm 4, or the position of the V-shaped groove on the tenon 1, it is possible to precisely determine the desired spacing between the side end of the crossbar T and the sidepiece F, so as to impart an adequate compression to the thermoplastic material 9 which allows to achieve the desired balance between coupling joint rigidity and an even stress distribution over the overall contact surface.
the arm 4 tightening by the screw V is carried out in opposition to the action of a lamina spring 7, one end of which is housed in a slit 2g formed in the support body 2, and the other free end operates on the oscillating arm 4.
the oscillating arm 4 rotates, anticlockwise in the drawings, under the action of the spring 7, up to a disengagement position wherein the tenon 1 is automatically released, and a quick and easy removal of the sidepiece F from the cavities C of the crossbars T is thus allowed, as well as an equally quick and easy reinsertion into position of the same, upon completion of the textile operations on the healds.
the sidepiece/crossbar coupling joint of the present invention has been described with reference to only one of the four corners of the heald frame, precisely the one between the upper crossbar and one of the sidepieces. It is however evident that the same type of coupling, with a symmetrical structure with respect to a horizontal median axis of the heald frame, is identically used for coupling the lower crossbar with the lower end of the same sidepiece. Similarly, the coupling joints of the two crossbars with the other sidepiece of the heald frame will have a symmetrical structure to those described above, with respect to a vertical median axis of the heald frame.
this reinforcing element consists of a sleeve 11, preferably of aluminium alloy, which outwardly wraps the outline of the crossbar T and bears a through hole 12 at its top for housing the screw V, as schematically illustrated in Fig. 6 .
the crossbar T is also provided with a lower notch 14, in addition to the traditional upper notch 13 giving access to the screw V. Thanks to the provision of the notches 13 and 14 it is therefore possible to achieve the insertion of the sleeve 11 onto the end of the crossbar T.
the sleeve 11 can be easily obtained by cutting out a suitable extruded aluminium alloy profile, and significantly contributes to counteract the crossbar T deformations induced by the screw V tightening. Thanks to this sleeve, stresses are distributed over a much wider surface of the crossbar T than using only the traditional internal insert 10 and, furthermore, local deformations of the crossbar T are prevented. By this solution the desired improvement of the mechanical strength of the sidepiece/crossbar coupling system is further achieved, without increasing the wall thickness of the crossbar itself, thus avoiding increasing the heald frame overall weight.
the more rigid elements of the coupling joint namely the sidepiece F, the crossbar T and the arm 4, are never in mutual direct contact, thanks to the interposition of the coverings 8 and 9, the bush 6 and the support body 2 itself, all made of thermoplastic material.
thermoplastic material is characterised by an elastic modulus low enough to allow mutual micro-displacements of the rigid elements of the coupling joint, thus avoiding the onset of peaks of stress that are dangerous for the structural integrity of such elements, without however altering the macroscopic shape of the heald frame that therefore behaves like a perfectly rigid heald frame as regard the weaving.
the particular configuration of the intermediate element comprising support body 2 and the oscillating arm 4 directly hinged on the crossbar C and maintained in an open position by the lamina spring 7, makes the sidepiece F immediately removable as soon as screw V is unscrewed, considerably speeding up the operations of opening and closing the heald frame.
the sleeve 11 forms a reinforcing element which significantly contributes to distribute on a wider surface the local stresses of the crossbar, without substantially increasing the heald frame overall weight.
