- the device is mounted on an amount of the heald frame.
- the invention finally relates to a loom equipped with at least one actuating mechanism as mentioned above.
- the invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of two embodiments of a hooking device, a heald frame, a actuating mechanism and a loom according to its principle, given by way of example only and with reference to the accompanying drawings, in which:
- FIG. 1 is a schematic representation of a weaving machine according to the invention.
- FIG. 2 is an enlarged view of detail II in FIG. 1;
- FIG. 2A is a partial section on a larger scale along the line A-A in Figure 2;
- FIG. 3 is an exploded perspective view of the elements visible in FIG. 2;
- - Figure 4 is a view similar to Figure 2 during the attachment of the rod and the frame;
- - Figure 5 is a view similar to Figure 4 at the end of the relative approach movement of the rod and the frame; - Figure 5A is a partial section on a larger scale along line AA in Figure 5; and
- FIG. 6 is a view similar to Figure 2 for a latching mechanism according to a second embodiment of the invention.
- a dobby 1 is intended to drive a heddle frame 2 of a loom M in an oscillating vertical movement represented by the arrows Fi and F'i.
- an actuating arm 11 of the dobby 1 is coupled, by connecting rods 3 and oscillating levers 4, to the frame 2.
- the trade M comprises several frames, only one of which is shown in FIG. 1 for the sake of clarity. drawing.
- the two rods 3 which attack the frame 2 have their respective upper ends 31 configured in a loop and which each define a bore 32 of circular section centered on an axis X 32 .
- Each end 31 is integral with the rest of the connecting rod 3 corresponding. Alternatively, it may be an end reported.
- Two devices 5 intended to cooperate each with the end 31 of a driving rod 3 are fixed in the lower part of the lower cross member 21 of the frame 2.
- One of these devices is more particularly visible in Figures 2 to 5. It comprises a base flange 51 on which is riveted by means of a not shown rivet, a pin 53 projecting from the face 51a of the flange 51 shown in Figure 3.
- the pin 53 is circular outer section centered on an axis X 53 .
- a bar 54 is used to fix the device 5 on the cross member 21 by means of two screws 55 represented by their center lines.
- a front flange 56 is disposed parallel to the flange 51 to which it is rigidly associated by five rivets, namely three rivets 57a through holes 54a formed in the bar 54 and two stepped rivets 57b of larger section than the rivets 57a.
- the pin 53 is not riveted to the flange 51 by an independent rivet but immobilized thereon by plastic deformation or riveting of its rear part in Figure 3.
- a plastic latch 58 is pivotally mounted around one of the rivets 57b, that is to say about its longitudinal axis Xs 7 which is perpendicular to the flanges 51 and 56. In the mounted configuration of the device 5, the latch 58 is interposed between the two flanges 51 and 56.
- the latch 58 comprises a heel 58a intended to cooperate with the face 31b of the end 31 of the rod 3 located opposite the flange 51 when the end is received in the device 5 in snap configuration.
- the surface 31a is circular, with a rectilinear generatrix and with a circular section centered on the X axis 32 of the bore 32.
- the heel 58a has, on its side facing the flange 56, a return 58b which partially covers the face 31b when the latch 58 holds the end 31 around the pin 53.
- the return 58b prevents the end 31 from moving away from the flange 51 when it has been put in place around the pin 53.
- the return 58b immobilizes the end 31 parallel to the axes X 32 and X 5 3 which are then confused.
- the axis X 5 3 forms an axis of articulation for the connecting rod 3 which can oscillate, with an angular amplitude of a few degrees, about this axis, as represented by the arrow P in Figure 2.
- the bore 32 is equipped with a sliding ring 34 on the pin 53.
- the pin 53 thus defines, by its central axis of symmetry X 53 , an axis of articulation of the connecting rod 3 on the frame 2.
- the latch 58 comprises an operating lug 58d which extends substantially opposite the bead 58a with respect to the X axis 57 in the mounted configuration of the device.
- the latch 58 also comprises a resilient tongue 58 which bears against the surface 54d of the bar 54 facing the pin 53, as can be seen in FIG. 2.
- the tongue 58e which is integral with the rest of the latch 58, is configured to exert on it a torque C tending to tilt the heel 58a about the axis Xs 7 towards the X axis 53 and the surface 31a when the rod 3 is in place around the pin 53.
- FIGS. 4, 5 and 6 For the sake of clarity, the parts shown in dashed lines in FIG. 2 are omitted in FIGS. 4, 5 and 6 because they are masked by the flange 56.
- the flange 56 is generally U-shaped inverted and comprises two arms 56a and a base 56b connecting these two arms. Between the arms 56a is defined an opening O 56 which is open on the lower side of the flange, that is to say on its side facing the running portion 33 of the connecting rod 3, in the hooked configuration of the connecting rod and the frame .
- a lateral boss 58f formed on the latch 58 defines a surface 58g which bears against the outer edge of the arm 56a when the latch 58 is subjected to the only couple
- the arm 56a thus constitutes an abutment to the movement of the latch 58 under the effect of the C pair.
- the inner edges 56c of the arms 56a are decomposed into two concave portions 56c1 and 56c2, the portions 56c1 being configured in an arc of a circle, with a radius R 56 substantially equal to the radius R 31 of the surface 31a.
- the portions 56c 2 define with the edge 56d of the base 56b a recess.
- the portions 56c ⁇ of the edges 56c make it possible to guide the frame when the frame 2 is hooked onto the link 3 so as to align the X axis 32 with the X axis 53 of the pin 53.
- the operator can bring, judged, the device 5 generally above the end 31a, as shown in Figure 4, then move the frame 2 through a force F 2 in translation parallel to the flanges 51 to bring the edges 56c into pressing on the surface 31a of the end 31.
- the edges 5 ⁇ c are convergent from the free end of the arms 56a, that is to say the lower side of the flange 56, to the edge 56d.
- the arms 56a are configured so that the portions 56c ⁇ are centered on the X axis 53 so that, by its contact with these portions 56ci, the end 31 and its bore 32 are automatically centered on the axis Xs 3 , when the device 5 is moved by the force F 2 .
- the end 31 comes, by a portion 31a ⁇ of its surface 31a, bearing against the internal radial surface 58c of the return 58b to which it transmits a force F ' 2 which is the result of the effort F 2 .
- the return 58b and the heel 58a are thus pushed back by the force F ' 2 , as shown in FIG. 5, against the torque C, in a rotational retraction movement. around the latch 58 about the X axis 57 , as illustrated by the arrow E 58 in Figure 5.
- the latch 58 is reduced, under the effect of the torque C exerted by the tongue 58e, to the position of Figure 2 where the return 58b retains the end 31 in place between the two flanges 51 and 56, opposing an extraction movement parallel to the X axis 33 and directed away from the flange 51.
- the movement of the frame 2 and the device 5 is an approach movement in which the device 5 is guided by its edges 56c x on the surface 31a of the end of connecting rod 31.
- the rod end 31 is guided by the edges 56C 1 .
- the relative guidance between the device 5 and the end 31 has the effect of aligning the X 32 and X axes 53 , which then makes it possible to easily engage the end 31 around the member 53, that is to say, to engage the member 53 in the bore 32. This results in an automatic locking of the connecting rod 3 in the device 5, without it being necessary for the operator to act directly on the latch 58.
- the hooking can be achieved without the operator visually controlling the pre-alignment of the end 31 and the device 5.
- the shape of the flanges 51 and 56 is modified to allow the mounting of the device 5 on a vertical post 22 of the frame 2.
- the flange 56 is extended by a tab 5 ⁇ e which overlaps a portion of the upright 22.
- the flange 51 is also extended by a leg of the same type.
- the legs 56e and equivalent of the two flanges are assembled by means of rivets 57a which pass through the post 22. The attachment of the device 5 to the frame 2 is thus performed without resorting to a bar of the type of the bar 54 of the first embodiment.
- the invention has been shown for a frame driven by dobby 1. However, it is applicable regardless of the exact type of armor mechanics which may be a basic armor mechanics.
- the portions 56ci are not necessarily in an arc. They can take any form adapted according to the geometry of the part of the external surface 31a with which they cooperate which is not necessarily circular section. In particular, the edges 56c can be configured in V, while the end 31 is generally in peak shape.
- the hooking mechanisms can be arranged on the underside or on the top of the frame, according to the configuration of the transmission rods of the movement of the armor mechanics.
