Definitions

  • the present invention relates to a device for a roll-up of a single-twist mesh in which the rows of meshes are folded back on themselves around their center line of articulation, alternately in one direction and in the other so as to obtain a sort of folding accordion, as well as a folding device capable of being used in this winding device to fold on themselves, around their median line of articulation, the rows of stitches of such a mesh , that is to say, to obtain the aforementioned accordion folding.
  • Such mesh rolls are known from French Patent No. 1,594,975.
  • This patent describes a device allowing such a rolling of a single-twist wire mesh.
  • This device comprises two spool winding drums arranged downstream of an advance drum bringing the wire mesh from a manufacturing installation. The peripheral linear speed of these winding drums is reduced to a fraction of that of the feed drum so that the wire roll which forms in the V-shaped area between the two winding drums is shaped as this is stated above.
  • This device is generally satisfactory but has the drawback, however, that, in order to obtain a suitable ordering of the links, the mesh must be brought to low speed and that consequently the usual manufacturing installations must operate at a speed lower than their speed. nominal resulting in a significant decrease in their performance.
  • the present invention aims to provide a roll setting device which can be used downstream of a plant for manufacturing single-twist mesh operating at its nominal speed and making it possible to obtain more regular windings than known devices, and provides for this purpose a device for folding down on themselves the rows of meshes of such a mesh supplied in the form of an extended tablecloth.
  • a device for folding down on themselves around their median line of articulation the rows of meshes of a single twist mesh fed in the form of an extended ply is characterized in that it comprises at least two supports for said mesh ply, elongated in the direction of supply of the mesh and separated from each other by a distance substantially equal to a multiple of the diagonal of the mesh of the mesh considered.
  • Said supports can, for example with the horizontal, form an angel of 40 ° in order to ensure the advancement of the web during folding and, to facilitate folding.
  • said supports each comprise an angle iron having an edge directed upwards.
  • Said angles preferably extend from the outlet drum of an installation for manufacturing such a mesh, and curved bars are fixed to the upstream ends of the angles and are partially wound around said drum.
  • said supports each comprise a strand of a member such as a chain.
  • Said chain is then preferably driven by a longitudinal speed lower than the feeding speed of the mesh.
  • said strand of the member such as a chain is substantially in the extension of the edge of said angle.
  • the invention also relates to a device for a roll-up of a single-twist mesh in which the rows of meshes are folded back on themselves around their median line of articulation, characterized in that it comprises a device as described above.
  • Such a roll-up device may comprise means for receiving formed from at least two V-shaped assemblies each of two strands of a member such as a chain, said supports then comprising the upstream strand of said shaped assemblies.
  • the portion of the simple twist wire mesh shown in FIG. 1 is formed by a plurality of strands of metal wire 101, 102, 103 and 104. Each wire forms a broken line so that it lies entwined on one of its sides with the thread which precedes it and on the other side with the thread which follows it, thus forming diagonal stitches d.
  • FIG. 2 represents a mesh ply such as the ply 100 after the rows of stitches have been folded back on themselves around their median line of articulation.
  • the row formed by the son 101 and 102 is folded around the line 105 then the row of stitches formed by the threads 102 and 103 is folded around the line 106 in the opposite direction and the row of stitches formed by the wires 103 and 104 is connected around the line 107 in the same direction as the row formed by the wires 101 and 102.
  • FIG. 2 If the structure of FIG. 2 is wound up on itself, a roller 50 is obtained, part of which is shown in FIG. 3.
  • the external generatrices of this roller form, as shown in this figure, a succession of chevrons 53, with inner edges 51 and outer edges 52.
  • the device according to the invention shown in Figures 4 to 6 comprises a frame 1 disposed downstream of a single twist wire mesh installation, of which only the outlet drum 2 is shown in the drawings.
  • the output drum 2 rotates when this installation is in operation at a speed which is a function of the predetermined speed at which the mesh is produced and advances at the output of this installation.
  • the mesh is therefore provided at this speed by the outlet drum 2 in the form of an extended ply. This ply is guided laterally by means of two cheeks 3 mounted on the outlet drum 2.
  • the frame 1 carries immediately downstream of the drum 2 a bar 4 and downstream of this bar 4 a second bar 5.
  • the angles 6 are distributed along the bars 4 and 5 between the cheeks 3 at approximately regular intervals.
  • the distances which separate the different angles 6 from each other are substantially equal to a multiple of the diagonal of the mesh of the mesh which is to be rolled.
  • curved bars 14 are fixed to the upstream ends of the angles 9 and are partially wound around the drum 2.
  • the device also comprises a drive shaft 10 which carries a chain wheel 11 capable of cooperating via a chain 12 with another chain wheel 13 (FIG. 4) mounted on the shaft of the output drum 2.
  • a drive shaft 10 which carries a chain wheel 11 capable of cooperating via a chain 12 with another chain wheel 13 (FIG. 4) mounted on the shaft of the output drum 2.
  • Another shaft 16 is mounted in the frame 1 and carries a chain wheel 17.
  • This wheel 17 is provided to cooperate with a chain wheel 18 (FIG. 5) mounted on the shaft 10 at its end opposite to the wheel 11.
  • the wheel 18 therefore drives the wheel 17 and therefore the shaft 16 at a speed which depends on the ratio existing between the wheels 17 and 18.
  • a tensioning pinion 20 whose axis is capable of sliding in slides 21 mounted on the frame 1 makes it possible to ensure the tension of the chain 19 for different ratios of the wheels 17 and 18. It is thus possible to adjust the ratio of the rotational speeds of the shaft 16 and of the output drum 2 of the installation for manufacturing the mesh .
  • the shaft 16 carries a plurality of upstream chain wheels 24 which are arranged on this shaft so that each is located outside one of the angles 6.
  • articulated arms 27 at the ends of which downstream chain wheels 28 are mounted are rotatably mounted around bearings 31 concentric with the shaft 23 and consequently with chain wheels 26, these bearings being carried by the plates 39.
  • the arms 27 are secured to each other in rotation by a shaft 29 passing through the axes of the wheels 28.
  • levers 30 integral with the arms 27 are also capable of pivoting around the bearings 31 and carry at their end chain wheels which are located in the same planes as the wheels 28.
  • the arms 27 and the levers 30 which are integral with each other are arranged on the bearings 31 so that the wheels 28 and 32 are located in the same planes as the wheels 24, 25 and 26.
  • Another shaft 33 is carried by the frame 1 and supports chain wheels 34 each arranged in one of the planes defined by the wheels 24, 25, 26, 28 and 32.
  • the shaft 35 carries two cheeks 36 mounted on sliding bearings 37 and capable of being adjusted to lie in the same plane as the cheeks 3 of the output drum 2.
  • the cheeks 36 can be fixed in position by means of members 38 provided on the bearings 37.
  • each plate 39 has a groove 40 (FIG. 4), in which the axis of a chain wheel 41 can slide.
  • the axis of the wheel 41 is biased downwards, that is to say say on the side opposite to the wheels 24 and 28 relative to the wheels 25 and 26, by a spring 42, one end of which is mounted on the axis of the wheel 41 and the other end is integral with an extension 43 of the plate 39.
  • chains 44 pass over each of the sets of wheels 24, 25, 26, 28, 33 and 41. Between the wheels 24 and 25 on the one hand and the wheels 26 and 28 on the other hand, the strands 45 and 46 respectively of the chain form a V as can be seen in FIG. 4.
  • the upstream strand 45 which is substantially in the extension of the upper edges of the angles 6 makes an angle of substantially 40 ° with the horizontal and the downstream strand 46 makes itself with the strand 45 an angle which is also substantially equal to 40 °.
  • shaft 5 is mounted movable in rotation relative to the frame 1 which can be actuated using a counterweight 47.
  • Fingers 48 are integral with the axis 5 so that they pivot with the latter when the counterweight 47 is tilted.
  • the reels 60 make it possible to wind the wires at the same time as the wire mesh.
  • These threads which facilitate the folding of the meshes and ensure their ordering therefore make it possible to perfect the herringbone configuration of the roller. Furthermore, they make it possible to maintain the meshes during the rotation of the roller and facilitate the correct unwinding thereof, during its use.
  • this ratio can be equal to 0.25.
  • the counterweight 47 being in a position such that the fingers 48 are erased relative to the angles 6, the mesh is brought on these angles to the strand 45 of the chains 44.
  • the device is in the configuration shown in Figure 7 with strands 45 and 46 stretched and the axes of the wheels 41 at the bottom slides 40 where they are held by the traction of the springs 42.
  • the normal position for the arms 27 and the levers 30 is that shown in FIG. 7 in which the strands 45 and 46 form a V and in which the wheels 32 are separated from the arm 45.
  • the wire mesh is interrupted between the output drum 2 and the axis 5 and the fingers 48 are tilted in the position shown in FIG. 4. Consequently the part of the wire located downstream of the interruption completes the roller 50 while the upstream part is blocked by the fingers 48, so that the mesh can continue to be fed by the output drum 2 during the maneuver described below during which the roller 50 is removed from the device.
  • the set of arms 27 is tilted downwards in the position shown in FIG. 9, driving with it the shaft 29 and the chain wheels 28. In this movement, the levers 30 are also tilted and they drive the wheels 32 .
  • the strand 46 of the chain 44 becomes substantially horizontal while the wheel 32 deforms the strand 45 which thus causes the roller 50 to tip over onto the horizontal strands 46 from which it can be removed.
  • the arms 27 are then returned to the position they occupy in FIGS. 4 and 7.
  • the fingers 48 are again retracted so that a new grid of mesh comes to take place between the strands 45 and 46 where it begins to s' wrap as described with reference to figure 7.
  • the invention therefore provides a device for putting a single-twist mesh in a compact roll, without it being necessary to stop the installation for manufacturing this mesh during the handling of the finished rolls. It has also been found that it is thus possible to obtain a very high regularity of winding.
