Definitions

  • the invention relates to a rotating dobby for the control of heald frames mounted on a loom, and to a loom equipped with such a dobby.
  • the invention also relates to a driving element belonging to such a dobby.
  • EP-A-0 851 046 EP-A-0 851 045 to equip a rotary dobby of an oscillating piece for each of its blades, this part being coupled to a heddle frame and associated with an eccentric mounted crazy on a main shaft of the dobby.
  • a movable ratchet makes it possible to couple a plate integral with the eccentric and carrying this member to a disc-shaped drive member, itself rotatably connected to the main shaft of the dobby.
  • this drive element is provided with two diametrically opposed notches in each of which can be received a finger belonging to the pawl. This finger comes, by its lateral faces, bearing against the edges of the notch in which it is engaged, which allows to drive the plate or to brake according to the movements of the drive element, itself even rotated by the main shaft of the dobby.
  • the rotating dobbies must be able to operate at higher and higher speeds, which has led to optimizing the zones of interaction between pivoting levers controlled by a device for reading the dobby and corresponding wedging surfaces formed on the tray, as is apparent from EP-A-0 851 046 . These arrangements are satisfactory.
  • the invention more particularly intends to remedy by proposing a new rotary dobby in which the premature wear of the parts in contact with the pawl and the driving element is greatly reduced or even eliminated.
  • This dobby is characterized in that the height of the orthogonal projection, on the bisector of the lateral faces of the finger or on the bisector of the edges of the notch, of the second interface is greater than the height of the orthogonal projection of the first interface. on the same bisector.
  • the area of the braking interface between the finger and the notch in which it is engaged can be relatively large, so that sliding under load at this interface, slip that occurs during finger extraction during braking of the drive element, is distributed over a relatively large area.
  • the contact pressure is lower and the wear of the movable member and the notches of the driving element is reduced compared to the dobbies of the prior art.
  • the height of the second interface projected on the bisector is greater than that of the first interface projected on the bisector allows that, during the extraction of the finger, the stroke of the movable member may remain of low amplitude, this is particularly advantageous because, during this movement, the inertia of the adjacent pivoting lever and that of the movable member must be overcome, as well as the effort due to the first means elastic.
  • the area of the first interface can be kept relatively low because the driving force is exerted without relative movement between the driving part and the driven part, which is less severe in terms of wear of the parts. that the sliding force obtained at the second interface during the extraction of the finger.
  • the movable member tilts under the effect of the first elastic means and the inertia of the moving parts is smaller than in the case of the extraction of the finger, so that the stroke of the movable member may, in this case, be greater than the stroke of clearance or extraction of the finger.
  • the invention therefore makes it possible to provide a gain in terms of performance for the dobby, without additional cost compared with existing solutions, especially those known from EP-A-0 851 046 . Indeed, this solution involves only local geometrical modifications of the moving parts, in contrast to a solution where one or more specific surface treatments would be applied, which would be costly and poorly adapted to the manufacturing in large series of metal parts. In addition, the control modes of moving parts are not questioned by the invention.
  • the height of the orthogonal projection of the second edge on the bisector of the edges of each notch is greater than the height of the orthogonal projection of the first edge of the notch on the same bisector, the orthogonal projections of the lateral faces of the finger on the bisector of these faces having substantially the same height.
  • each notch is asymmetrical, its edge on the braking interface side being higher than its edge on the interface side engine.
  • the same drive element can be used in both directions of rotation of the dobby, provided to be returned to move from one direction to another.
  • the movable member or pawl is, for its part, identical and keeps the same position whatever the direction of rotation.
  • the end face of the finger of the movable member is at least partly substantially complementary to a portion of the outer radial surface of the driving element in the vicinity of the second edge of each of its notches, which allows the finger to slide easily on the outer radial surface of the drive element before entering the notch.
  • the height of the orthogonal projection of the second lateral face of the finger on the bisector of the lateral faces of this finger is greater than the height of the orthogonal projection of the first lateral face of the finger.
  • the orthogonal projections of the edges of the notches on the bisector of these edges having substantially the same height.
  • the drive device can be used in the same position, regardless of the direction of rotation of the shaft, two different types of movable members being used depending on the direction of rotation of the shaft. training.
  • the height of the orthogonal projection of the second edge, on the bisector of the edges of each notch is greater than the height of the orthogonal projection of the first edge of the notch on the same bisector, while the The height of the orthogonal projection of the second lateral face of the finger on the bisector of the lateral faces of this finger is greater than the height of the orthogonal projection of its first lateral face on the bisector of these faces.
  • the radial height of the interfaces is optimized, an adaptation of the movable member and the drive element in the direction of rotation of the shaft.
  • the end face of the finger of the movable member may be substantially complementary to the bottom of the notch.
  • the bisector of the first and second lateral faces of the finger and / or the bisector of the first and second edges of each notch is or are merged with a radial radius by relative to the geometric axis of rotation of the drive shaft.
  • these faces and these edges may be parallel to such a radius which is then coincident with the aforesaid bisectors.
  • each notch may comprise a rounded central relief of support of the end face of the movable member.
  • the invention also relates to a loom equipped with a dobby as described above.
  • a loom is more reliable and easier to maintain than those of the state of the art.
  • the invention finally relates to a driving element belonging to a dobby as mentioned above and, more specifically, to a driving element provided with two notches intended to selectively receive a finger belonging to a mobile coupling member carried by the plateau, while the height of the orthogonal projection of an edge of each notch intended to transmit to the finger a braking force of the plateau on the bisector of the edges of this notch is greater than the height of the orthogonal projection, on the same bisector, an edge of each notch for transmitting to the finger a drive motor drive in rotation of the plate.
  • the dobby R represented at Figures 1 to 3 comprises a main shaft 1 animated by an intermittent rotation movement, with stopping every half-turn.
  • This shaft receives bearings 1a in number equal to that of the heald frames or blades of the craft.
  • On each bearing 1a is mounted idler an eccentric 2 secured laterally to a plate 3.
  • Around each eccentric 2 is mounted, with the interposition of a bearing 2a, a connecting rod 4 whose free end 4a is coupled to a pivoting arm 5 which ensures, thanks to a connection rods 6a, the vertical movement of the heald frame or blade 6 considered.
  • This framework is very schematically represented in the figure 1 .
  • the trade M thus comprises the dobby R represented on the left of the figure 1 , as well as several frames of the frame type 6, each frame being moved according to a vertical oscillations movement represented by the double arrow F 1 , by a lever 5, itself actuated by a connecting rod 4.
  • X 1 denotes the longitudinal geometric axis of the shaft 1, this axis constituting the axis of rotation of this shaft.
  • the shaft 1 carries a drive member 7 of elongate shape and whose central opening is substantially circular and centered on an axis X 7 .
  • the central opening of the member 7 is provided with two teeth 71 engaged in longitudinal grooves of corresponding shape formed at the periphery of the shaft 1.
  • the axes X 1 and X 7 are merged.
  • the member 7 is integral in rotation with the shaft 1.
  • the member 7 is provided with two notches 72 arranged on the same diameter D 1 of the shaft 1, symmetrical with respect to this diameter and intended to selectively receive a finger 81 of a pawl 8 articulated on an axis 9 carried by the plate 3 integral with the eccentric 2 corresponding.
  • a spring 10 tends to permanently recall the finger 81 of the pawl 8 towards the shaft 1, that is to say to engage the finger 81 in one of the notches 72 when disposed opposite this finger.
  • each lever 11 has a generally angled profile and is biased by a spring 13 in order to come into abutment with a shank 111 against a corresponding fixed abutment 14.
  • the shank 111 of each lever 11 can be selectively controlled by a pusher (not shown) reading, as represented by the arrows 15.
  • each lever 11 is provided with a spout 112 provided to cooperate with two wedging surfaces 31 and 32 formed at the periphery of the plate 3.
  • the spring 13 form an elastic means which tends to engage the nose 112 of each lever 11 with one of the two wedging surfaces 31 and 32. Thanks to the spouts 112 and surfaces 31 and 32, the plate 3 can be immobilized in two positions separated by a 180 ° rotation of the shaft 1. More specifically, the plate 3 can be immobilized in the position of the figure 1 or in a position in which the surface 31 cooperates with the spout 112 of the lever 11 shown on the left of this figure, while its surface 32 cooperates with the spout 112 of the lever shown on the right of this figure.
  • the springs 13 act on the levers 11 so that the nozzles 112 engage with the surfaces 31 and 32 when they arrive opposite the one of these spouts due to the rotation of the shaft 1.
  • This has the effect of exerting on a tail 82 of the pawl 8 a centripetal force F 2 which rotates the pawl in the direction of the arrow F 3 to the figure 1 , against the action of the spring 10.
  • the finger 81 is thus clear of the notch 72 in which it was previously introduced.
  • This engagement of the nozzles 112 with the surfaces 31 and 32 has the effect of immobilizing the plate 3 angularly and with it the eccentric 2 and the connecting rod 4 which are integral in rotation of this plate.
  • the member 7 can therefore be driven over a 180 ° stroke by the shaft 1, without itself driving the plate 3, the eccentric 2 and the connecting rod 4.
  • the rotational movement F 4 of the member 7 around the axis X 1 is transmitted to the finger 81 at an interface I 1 through which passes a motor force F 5 of the member 7 to the finger 81
  • This force is exerted by a first edge 721 of the notch 72 against which is supported a flat lateral face 811 of the finger 81.
  • the interface I 1 is formed by the portions bearing the edge 721 and the face 811. It constitutes a "motor" interface for driving the pawl 8 and elements 2, 3 and 4 associated.
  • the thickness of the edge 721 and the face 811 perpendicular to the plane of the figure 2 is limited by the width available for the placement of elements 7 and 2 in the division of the trade, this division being generally between 10 and 20 mm. It is therefore not possible to act on this width to increase the contact area between the edge 721 and the face 811. However, this area can be relatively small since the effort F 5 is a variable effort which is exercised while the edge 721 remains fixed relative to the face 811, when the member 7 drives the pawl 8.
  • the finger 81 also carries, by a flat lateral face 812 opposite the face 811, against a second edge 722 of the notch 72, this at an interface I 2 at which a braking force F 6 is transmitted.
  • the interface I 2 thus constitutes a braking interface between the pawl 8 and the member 7.
  • the faces 811 and 812 and the edges 721 and 722 are shown as not being supported, which is the case in certain phases of movement due to possible functional gaps.
  • the interfaces I 1 and I 2 extend over the height of the plane portions of the faces 811 and 812 and the edges 721 and 722 which are capable of coming into surface abutment against each other.
  • B 1 is the bisector of faces 811 and 812.
  • B 2 is the bisector of the plane portions of edges 721 and 722.
  • these bisectors are merged with each other and with a radius R 1 radial to the axis X 1 and passing equidistant from the faces 811 and 812.
  • the finger 81 When the force F 6 is applied, that is to say while the elements 1 and 7 are being decelerated, the finger 81 begins to be removed from the notch 72, in the direction of the arrow F 7 to the figure 2 , which induces a sliding under load of the face 812 against the edge 722, in the direction of the arrow F 8 to the figure 2 .
  • the height H 1 of the orthogonal projection I ' 1 of the interface I 1 on the bisector B 1 is not increased so as not to hinder the disengagement movement F 7 of the finger 81 when it is appropriate to to extract from the notch 72 under the effect of the force F 2 .
  • the performance of the extraction control remains the same when the race and the extraction rate remain unchanged.
  • the performance of the extraction control is not reduced.
  • the height H 2 is greater than the height H 1 . Taking into account the fact that the thickness of the parts 7 and 8 is uniform, this induces that the interface I 2 has an area greater than the interface I 1 , which allows optimized transmission of the forces at the time when the driving of the pawl 8 by the member 7 and during the release or extraction of the finger 81 relative to the notch 72.
  • edges 721 and 722 of the notch 72 are generally parallel to each other and to the bisector B 2 .

  • the dobby is in the configuration of the figure 3 .
  • the face 813 is configured to slide then on the outer radial surface 73 of the member 7 in the direction of the arrow F 9 , before the finger 81 is engaged in the notch 72 under the effect of the elastic force of spring 10, this as soon as the notch 72 reaches opposite this finger 81.
  • the face 813 is substantially complementary to the surface 73 in its adjacent portion of the edge 722 of each notch.
  • only part of the face 813 may be substantially complementary to the surface 73.
  • the difference in the radial heights H 2 and H 1 is related to the fact that the orthogonal projection of the edge 722 on the bisector B 2 has a height h 2 greater than the height h 1 of the orthogonal projection of the edge 721 on this bisector B 2 .
  • the orthogonal projections of the faces 811 and 812 on the bisector B 1 have heights h ' 1 and h' 2 substantially equal.

  • the disc 7 is provided with four teeth 71 for securing in rotation with the shaft 1 and two notches 72 diametrically opposed along a radius D 1 perpendicular to the X axis 1 of rotation of the shaft 1.
  • a pawl 8 is pivotally mounted on an axis 9 carried by a plate 3, this pawl 8 being subjected to the action of a spring 10 tending to engage a finger 81 of the ratchet in one of the notches 72.
  • the shaft 1 rotates clockwise at the figure 5 , as represented by the arrow F 4 , that is to say in a direction opposite to the direction of rotation of the shaft 1 to Figures 1 to 3 .
  • the transmission interface of the motor force F 5 between the disk 7 and the finger 81 is respectively denoted I 1 , this interface being defined between a first flat lateral surface 811 of the finger 81 and a first edge 721 of the notch 72.
  • I 2 note the braking interface between a second flat lateral face 812 of the finger 81 and a second edge 722 of the notch 72, the braking force F 6 of the finger 81 being exerted at this interface to the end of 180 ° rotation of the shaft 1.
  • the orthogonal projection I ' 2 of the interface I 2 on the bisectors B 1 and B 2 has a height H 2 greater than the height H 1 of the orthogonal projection I' 1 of the interface I 1 on these bisectors.
  • the orthogonal projections on the bisector B 2 of the edges 721 and 722 have substantially the same radial height, h 1 and h 2 , whereas the height h 2 of the orthogonal projection of the face 812 on the bisector B 1 is greater than the height h ' 1 of the orthogonal projection of the face 811 on this bisector B 1 .
