Definitions

  • the invention relates to a flexible lance control device and to a loom equipped with at least one such device.
  • the invention intends to remedy more particularly by proposing a new flexible lance control device which is compact, capable of generating motion laws compatible with those of a flapper and whose reliability is satisfactory.
  • the direct articulation of the connecting rod on the part provided with the toothed part allows efficient transmission of movement and with little clearance between the ring gear and the toothed wheel. Thanks to this mode of transmission of movement and the arrangement of the crown and the connecting rod, the control device according to the invention can be compact and the inertia of moving parts can be low.
  • the invention also relates to a loom equipped with at least one flexible lance control device as mentioned above.
  • Such a loom is more economical, more reliable and easier to operate than those of the state of the art.
  • the drive means for rotating the crown of two flexible lance control devices of this trade are common.
  • the crowns of two control devices can be driven by the same shaft which extends parallel to the insertion direction of the frame.
  • This shaft may be an output shaft of a drive motor of a pinion engaged with the ring gear. It can also be a tree common to the crowns of the two devices. It can further be provided that the control device of the fly of the trade is also driven by the crown drive shaft.
  • the trade M represented at figure 1 comprises a beam 1 from which are unwound son of chain 2 of which only some are shown in the figures and which together form the crowd 3 of the trade being controlled by unrepresented smooth.
  • X 1 is an axis parallel to which the warp son are moved in the loom M, this axis is sometimes referred to as "chain axis”.
  • a weft yarn 4 is introduced into the shed by being moved along an axis X 2 perpendicular to the axis X 1 and most often called "insertion axis weft".
  • the wire 4 is secured to the clamp 51 of a so-called flexible lance 5 which also comprises a flexible tape 52 through which is obtained the reciprocating movement of the clamp 51 in the crowd 3 along the X axis 2 .
  • the movement of the lance 5 is controlled by a device 10 which is more particularly visible to Figures 2 to 5 and which comprises a frame 101 forming an oil sump and on an outer side of which is mounted a gear 102 rotating about an axis X 102 substantially parallel to the axis X 1 when the device 10 is in place on the loom M
  • the wheel 102 is provided at its periphery with teeth 102a intended to be engaged in openings 52a provided for this purpose on the ribbon 52, which ensures a rotational connection of the wheel 102 and the portion of the ribbon 52 wound on this wheel.
  • the X axis 102 is substantially parallel to the axis X 1 in that these angles form between them an angle less than 15 °.
  • the wheel 102 is rotated about the X axis 102 by means of an electric motor 103 controlled by a control unit of the trade M, according to its cycles of rotation. operation.
  • the output shaft 103a of the motor 103 drives a pinion 105 which rotates about an axis X 105 perpendicular to the X axis 102 and parallel to the axis X 2 .
  • the toothing 105a of the pinion 105 meshes with the toothing 106a of a ring gear 106 articulated about an axis X 106 parallel to the axis X 105 .
  • the X axes 106 and X 105 are fixed and defined by the frame 101.
  • the engine 103 is driven to cause the crown 106 to turn one turn for each pick of the craft.
  • a link 107 is articulated on the ring 106 about an axis X 107A parallel to the axis X 106 .
  • the rod 107 is disposed on the side of the ring 106 facing outwardly of the loom, that is to say opposite the crowd 3.
  • the radial position of the X axis 107A with respect to the crown 106 is adjustable by means of an adjustment device 110 which comprises two rails 110a mounted on the ring and delimiting a sliding volume of a pin 107A that defines the X axis 107A and on which is articulated the connecting rod 107.
  • Three screw 110b can immobilize the pin 107A along the rails 110a in the desired position.
  • the distance d 1 between the axes X 106 and X 107A is adjustable.
  • a lever 108 is articulated about an axis X 108 fixed relative to the frame 101 and parallel to the axis X 106 , this lever carrying a toothed sector 108a in the form of an arc to engage with a bevel gear 109 aligned on the X axis 102 and integral in rotation with the wheel 102.
  • the connecting rod 107 is articulated on the lever 108 around an axis X 107B parallel to the X axes 106 , X 107A and X 108 and fixed relative to the connecting rod 107 and the lever 108.
  • the articulation between the elements 107 and 108 is direct, in that there is no intermediate piece between the elements 107 and 108 and in that their axis of articulation X 107B is fixed relative to these elements.
  • a pin 107B is used to directly connect the elements 107 and 108 by defining the X axis 107B .
  • the toothed sector 108a engages the pinion 109, so that, because of the bevel gear formed between the parts 108a and 109, the pinion 109 is rotated about the X axis 102 and the toothed wheel 102 which is integral with the pinion 109 rotates about this axis, in the direction of the arrow F 2 to the figure 2 , which has the effect of moving the clamp 51 inwardly of the shed 3, in the direction of the arrow F 3 , by driving the weft thread 4.
  • the rod 107 and the lever 108 act as a crank articulation whose output movement is recovered by the pinion 109 to drive the wheel 102 alternately in the direction of the arrow F 2 and in the opposite direction. Since the X axis 107B is fixed with respect to the elements 107 and 108, the control of the lever 108 by means of the connecting rod 107 is accurate and durable.
  • the X axes 102 and X 108 are substantially in the same horizontal plane, while being perpendicular, while the pinion 109 and the sector 108a form a bevel gear.
  • the distance d 2 has a value between 340 and 360 mm, while the distance d 3 has a value between 28 and 32 mm.
  • the ratio d 2 / d 3 is between about 10.6 and about 12.9.
  • values of the ratio of d 2 over d 3 between 10 and 13 allow a very compact construction. Indeed, such a ratio of d 2 to d 3 allows a small overall height of the device 10.
  • d 4 the distance between the axes X 107B and X 108 .
  • This distance d 4 corresponds to the radius of curvature of the displacement movement of the X axis 107B around the X axis 108 .
  • 5 the distance between the X X 107A and 107B. This distance d 5 corresponds to the useful length of the connecting rod 107, between its respective axes of articulation on the ring gear 106 and on the lever 108.
  • P 102 is a median main plane of the wheel 102, that is to say a plane perpendicular to the X axis 102 and median between the faces of the wheel 102 visible respectively to the figures 2 and 3 .
  • This plane is fixed during operation of the device 10 and cuts the size of the ring 106, that is to say the volume in which this ring.
  • the trajectory of the X axis 107A can cut the plane P 102 at two points identified by the letters A and B respectively on the figures 4 and 5 .
  • the X axis 106 is arranged in height between the upper portions 102a 1 and lower 102a 2 of the toothing formed teeth 102a.
  • the X axis 106 is located generally at the same height as the wheel 102, more precisely in the vicinity of the X axis 102 . This gives a good compactness to the device of the invention, especially in comparison with known equipment.
  • the output shaft 103a of the motor 103 can be extended to drive a second device 10 'disposed on the other side of the loom and intended to drive a complementary lance of the lance 5.
  • a single motor 103 drives two control devices according to the invention, the device 10 'being, for the rest, similar to the device 10.
  • control device of the comb flap of the loom which is not shown in FIG. figure 1 for clarity of the drawing, can be driven by the shaft 103a.
  • the X axis 106 is parallel to the X 2 axis.
  • the shaft of the ring 106 can therefore extend through the loom M to drive the ring of a second device 10 'for the control of a lance complementary to the lance 5
  • the drive shaft is thus a shaft common to the rings of the devices 10 and 10 '. This traversing shaft performs one turn per pick and can advantageously also cause the control of the leaf.
  • This provides a simplification of the control members of different functions of the trade, which induces, in particular, a decrease in the inertia of moving parts and an improvement in the reliability of the trade.
  • a pinion 105 is driven as previously by the output shaft 103a of a motor not shown.
  • the pinion 105 is engaged with a ring 106 on which a rod 107 is hinged around an X axis 107A parallel to the insertion axis X 2 frame.
  • a wheel 102 similar to that of the first embodiment is engaged with the ribbon 52 of a flexible lance 5 whose clamp 51 must be moved along an axis X 2 perpendicular to the chain axis of the loom.
  • the wheel 102 is integral in rotation with a pinion 109 provided with an inclined toothing 109a.
  • the wheel 102 and the pinion 109 rotate about an axis X 102 perpendicular to the insertion axis of frame X 2 and substantially parallel to the chain axis in mounted configuration of the control device 10 on a loom.
  • the median main plane P 102 of the wheel 102 cuts the size of the ring 106.
  • This embodiment differs from the previous one in that there is no provision for a pivoting lever of the lever type 108 of the first embodiment but a slide 208 movable in translation parallel to a generally vertical axis X 208 in the mounted configuration of the device. 10.
  • the X axis 208 is perpendicular to the X axis 102 .
  • the rod 107 is articulated directly on the slide 208 about an axis X 107B materialized by a pin 107B visible in dashed lines at the figure 7 .
  • the X axis 107B is, as in the first embodiment, parallel to the axis X 2 and fixed relative to the rod 107 and the slide 208.
  • a crank-type joint is created by the parts 106 and 107 , which induces a reciprocating movement of the slider 208 parallel to the X axis 208 , this reciprocating movement being transmitted to the pinion 109 by means of a rack-like toothing 208a provided on the slider 208.
  • the axis of rotation X 106 of the ring gear 106 is arranged, in height, at the level of the wheel 102, that is to say between diametrically opposite zones 102a 1 and 102a 2 which define the upper and lower parts of its teeth 102a.
  • the slide 208 is guided in its displacement along the X axis 208 by two rods 209A and 209B which form guide rails of the slide and which absorb a torque that would tend to rotate the slide 208. Thus, no torque must be supported at the interface between the teeth 209a and 208a.
  • d 6 the distance between the axis X 106 of rotation of the ring 106 and a plane P 107 parallel to the axis X 208 and containing the axis X 107B . Given the drive kinematics of the wheel 102, the distance d 6 is constant during the rotation of the ring 106. This distance is advantageously between 8 and 11 mm.
  • the X axis 208 is not parallel to the main plane P 102 of the wheel 102 defined as in the first embodiment.
  • the angle ⁇ of inclination between this axis and this plane has no significant influence on the motion law generated for the lance 5.
  • the output shaft of a motor of the device 10 which is aligned with the X axis 105 of the pinion 105, itself parallel to the insertion axis weft, can be used to control both the device 10 and a similar device, the type of the device 10 'of the first embodiment.
  • the shaft of the ring 106 which is aligned on the X axis 106 . can be used for the same purpose.
  • the control device of the leaf can also be controlled by this output shaft or crown tree.
  • the invention has been shown in the case of its use for a single craft, it is however applicable to the double-ply looms and, in particular, carpet manufacturing trades.
