Definitions

  • the described technology generally relates to a rotary braiding machine for interweaving a strand shaped material, for example, a wire or textile fibers, carbon fibers or other strand shaped carbon materials, into meshes.
  • Such rotary braiding machines are used for fabricating hollow tubular meshes from the strand shaped material, such as metal wires, yarns or synthetic fibers, or (by subsequent roll threading of such a tubular mesh) for fabricating flat strand meshes or for braiding, for example, a cable with a wire mesh or for fabricating bodies of a low mass, for example, in a light weight construction, by braiding carbon fibers or of other strand shaped carbon materials.
  • the application fields for the technical meshes being fabricated in such a way are, for example, protective shieldings for electric cables against electromagnetic fields or protective enclosures for cables or hoses against mechanical stresses.
  • Another application is the fabrication of medical meshes for vascular implants, such as stents, vascular prostheses or the like.
  • One inventive aspect is a rotary braiding machine, for which a wire is the strand shaped material to be interweaved, e.g., for the fabrication of wire meshes.
  • a wire is the strand shaped material to be interweaved, e.g., for the fabrication of wire meshes.
  • this is not a limitation.
  • the described technology can also be applied to rotary braiding machines for the processing of any other strand shaped materials.
  • the rotary braiding machine includes a plurality of coils, each of which is arranged in a coil carrier.
  • a coil is a cylindrical, body for a winding of a wire to be interwoven, comprising, for example, two flanges, which are arranged at the ends of the cylindrical body, the flanges having a larger diameter than that of the coil body.
  • the coil carrier is a device into which a coil can be accommodated, for example, into which it can be mounted rotatably around its longitudinal axis.
  • the rotary braiding machine can be a high speed level braiding machine.
  • the rotary braiding machine has a braid axis, e.g., a geometric axis, in which direction the mesh is formed and is drown off by the machine, for example, by a stripping disk, and in which direction, if necessary, also the material to be interweaved is supplied to the machine.
  • the braid axis can be arranged horizontally, vertically or inclinedly, for example, inclined by 45 degrees, respectively. Embodiments are described in the following using the example of a rotary braiding machine with a vertically disposed braid axis, but it can also be applied to a rotary machine with a braid axis which has been arranged differently.
  • the rotary braiding machine includes a plurality of first coil carriers which can rotate around the braid axis, and a plurality of second coil carriers, which can perform a relative movement in regard to the first coil carriers.
  • at least the first coil carriers are guided along a closed guiding path around the braid axis.
  • a guiding path should mean a curve the first coil carriers are following essentially during their movement.
  • the first coil carriers do not necessarily have to lie on this curve and/or have to contact it.
  • the guiding path is formed, for example, as a circular rail and forms a plain bearing path or roller bearing path, onto which the first coil carriers are hung up and can be moved by means of sliding guides and/or rolling bearings.
  • first coil carriers rotate on a circular guiding path, wherein the braid axis is extending through its center.
  • second coil carriers move likewise around the braid axis, and for example, with the same speed as the first coil carriers, but in the opposite direction to the first coil carriers.
  • the second first coil carriers are mounted so that they can rotate around the braid axis as well.
  • Each first coil carrier provides a strand of a first wire, which is continuously unwound or drawn off from the first coil which is mounted on the respective first coil carrier.
  • each of the second coil carriers provides one strand of a second wire, which is continuously unwound or drawn off from the second coil which is mounted on the respective second coil carrier.
  • the first wires and the second wires are guided in a certain angle inward toward the braid axis, where they arrange themselves due to the rotation of the coil carriers and due to a simultaneous withdrawal movement of the mesh in spiral paths or are laid around the material to be braided, wherein the first wires are interwoven with the second wires.
  • the first wires and the second wires are crossed in a certain pattern, e.g., they lay above or below each other wire, respectively.
  • two adjacent second wires are each carried over two adjacent first wires, respectively and then carried under the next two adjacent first wires, respectively and so on (so-called “two over two braid binding”).
  • every second wire is alternately carried above a first wire and then carried below a first wire (so-called “one over one braid binding”).
  • the area, in which the crossed first and second wires lay against each other on the braid axis, is also called the braiding point.
  • the crossing over of the first and second wires is achieved in that the second wires are moved around periodically according to the desired cross over pattern around the corresponding first coil carriers and thus around the corresponding first wires.
  • this is achieved because every second wire can be raised over and can be lowered by a so-called thread lever, which is attached to the corresponding second coil carrier and which can be moved.
  • the considered second wire can be carried over the first coil carrier, which is moving past in the opposite direction, or it can be carried under the first coil carrier, which results in a corresponding crossing over of the first and the second wire with an above or an below laying second wire, respectively.
  • the entire second coil carriers which may have a substantial mass, due to the second coils mounted thereon and the second wires wound thereon, have to be raised or to be lowered as a whole.
  • every second wire can move all the way around every first coil carrier. Since the second wire is always guided in the direction of the braiding point, this results for this movement around the first coil carrier into an imaginary approximate conical surface.
  • the mounting of the first coil carrier on the closed guiding path has to be at least temporarily and/or at least partially interrupted, wherein the first coil carrier rotates around the braid axis on the guiding path, so that at this position the first coil carrier and second wire can cross their paths.
  • this is achieved in that the second wire is carried under the first coil carrier, which means that it “dives through” under the first coil carrier.
  • a vertical slit shaped gap is provided for the closed guiding path for the first coil carrier, wherein the respective second wire can be lowered into the vertical slit shaped gap, whereupon the first coil carrier passes over the lowered second wire.
  • gaps are distributed at regular intervals around the entire circumference of the guiding path arranged around at those positions where the second wires have to be lowered by means of their associated thread lever. Since the second coil carriers are fixedly connected to the guiding path, it is ensured that each second wire can be exactly immersed into the gap in the guiding path, without that a relative motion between the second wires and the gaps in the guiding path has to be considered.
  • Another aspect is an improved rotary braiding machine, especially with an improved guiding of the first coil carrier along the guiding path.
  • Another aspect is a rotary braiding machine with a braid axis for interweaving a wire to a wire mesh, the machine having a plurality of first coil carriers, which can rotate around the braid axis, and a plurality of second coil carriers, which can perform a movement relative in regard to the first coil carriers.
  • each first coil carrier has a first coil and provides a first wire
  • each second coil carrier has a second coil and provides a second wire.
  • the rotary braiding machine is adapted to interweave the first and second wires with each other.
  • at least a first coil carrier is arranged so that at least a second wire can be completely moved around the at least one first coil carrier. At least the first coil carriers can be guided along at least one closed guiding path, which is rotating around the braid axis.
  • the surface of at the least one closed guiding path is designed as a gear ring and the at least one first coil carrier has at least a gear wheel, which is rotatably mounted and which combs with the gear ring and which is engaged constantly with the gear ring, for example, also during the movement of the least one second wire around the at least one first coil carrier.
  • the “gear wheel” and “gear ring” can include a wheel or a closed, but not necessarily circular path, respectively, which is provided in its circumference or in its extension direction, respectively, alternately with teeth and tooth gaps, wherein the gear wheel can be engaged with the gear ring and it can be rolled off onto the gear ring.
  • the first coil carrier moves by the roll off movement of the gear wheel to the gear ring in a quasi-continuous manner, e.g., essentially with a uniform and a constant speed, for example, without any jerks or other short-term accelerations along the path.
  • the above mentioned problems in regard to the wear, the shocks, the vibrations and the noise emissions by constantly leaving the guiding paths by the guiding of and the rethreading of the guides in the guiding paths can be thus avoided to a large extent, because the combing of the gear wheels with gear rings is very well developed, for example, by the use of a special gearings as an involute gearing, and the called quasi continuous movement becomes possible. In this way, higher rotational speeds of the first coil carrier are possible and thus a rotary braiding machine with higher productivity can be achieved.
  • the gear wheels and the at least one gear ring can be, for example, made of a metal or of a plastic.
  • the latter allows for a dry run with a minimal lubrication or even without any lubrication.
  • an oil contamination of the rotary braiding machine can be avoided, the oil contamination due to the centrifuged oil droplets, and a potential contamination of the product can also be avoided.
  • certain products with higher quality standards requirements, for example for medical devices such pollutions may be even forbidden.
  • corresponding countermeasures against oil contamination such as oil drip plates are not necessary.
  • the uniform roll off movement of the gear wheels on the gear ring does not lead to an excessive heating of the guides of the first coil carrier or of the guiding path, respectively, so that costly measures for a monitoring of the temperature and for preventing overheating of the components of the engine are not necessary.
  • teeth gaps The spaces between adjacent teeth of the gear ring and the gear ring, respectively, are referred to as “tooth gaps” in the following.
  • a second wire can be immersed into a tooth gap between two adjacent teeth of the gear ring, while a first coil carrier having a gear wheel is moved past it.
  • sufficiently large dimensioning of the teeth compared to the diameter of the second wire e.g., for big teeth and thin second wires, there is no contacting between the second wire and the teeth of the gear wheel rolling over it, because the teeth when using a normal gearing do not contact the deepest points of the tooth gaps in the gear ring.
  • there will always be a continuous hollow space being transverse to the extending direction of the gear ring, through which the second wire can be guided.
  • the gear ring remains permanently engaged with the gear ring and does not have to leave the gear ring and to thread back to it again.
  • the surface of the at least one closed guiding path has at least one continuous recess being substantially transverse to the extending direction of the guiding path, which is deeper than the tooth gaps of the gear ring, wherein the at least one second wire is temporarily immersed in at least one recess during the movement of the at least one second wire around the at least one first coil carrier.
  • Such a recess is, for example, formed as a recess of a tooth gap of the at least one gear ring. Therefore, for the roll off movement of the gear wheel on the gear ring no changes arise, so that also a quasi-continuous movement of the first coil carrier on the guiding path is possible.
  • such a recess is provided for each second wire.
  • a device is attached to the at least one first coil carrier in the region of the gear wheel, wherein the device prevents the coil carrier from an axial displacement in at least one direction.
  • This device for example, has the form of a disk which is mounted coaxially to the gear wheel on the first coil carrier, for example, parallel and whose diameter is greater than the inner gear diameter, e.g., the distance from the center of the gear wheel to the deepest points of its tooth gaps.
  • the disk cannot move past the gear ring in the axial direction of the gear wheel, the gear ring being in engagement with the gear wheel, whereby the first coil carrier is prevented from an axial displacement in this direction.
  • the diameter of the disk is so small that the hollow space, which is intended for the passing through of the second wire, for example, the deepest point of a tooth gap in the gear ring or a recess in the guiding path will not be covered by the disk, and thus the disk does not contact the second wire, when the first coil carrier moves past it.
  • the disk may also have a larger diameter than those referred to and it can have in addition on its outer edge at least one recess through which the second wire can be guided, when the first coil carrier is moved past.
  • the positioning of the first coil carrier and the rotational movement of the gear wheel must be synchronized so that such a recess on the disk points in the direction of the gear ring at the moment, in which the gear wheel on the guiding path is directly over the hollow space for the passing through of the second wire.
  • two gear wheels are mounted rotatably on opposite ends of the first coil carrier coaxially or almost coaxially to each other.
  • two closed guiding paths are provided, which are designed as gear rings and which extend concentrically with the braid axis, but not necessarily in the same plane.
  • the first coil carrier two adjacent gear wheels can be attached, both of which comb with the same gear ring, or in each case two toothed wheels on both sides of the first coil carrier, respectively combing with a gear ring.
  • the first coil carrier is based stably on two or four points of contact with the gear ring and the gear rings, respectively and it cannot perform any inadvertent rotation around its own axis.
  • all the gear wheels are continuously engaged with the respective gear ring.
  • the two gear rings and the two gear wheels each have the same number of teeth.
  • the two gear wheels are connected by a common shaft and therefore synchronized in speed and they are, if necessary, connected to a balancing device for a possible angular offset between the axes of the two gear wheels.
  • the speed synchronization may, for example, also be done via a countershaft, which is arranged parallel to the axis of the two gear wheels and which is coupled, for example, by means of two other smaller gear wheels, meshing with the two gear wheels.
  • a gear wheel and a device are attached to opposite ends of the at least one first coil carrier, wherein the device prevents the coil carrier from an axial displacement in at least one direction.
  • the latter sliding locking device which is, for example, formed as already described above, then replaces one of the gear wheels in the above described embodiment with two gear wheels. Further, the respective gear ring is, for example, replaced by a guiding path with a smooth surface, on which the sliding locking device can roll off.
  • the first coil carriers move on a, viewed from the first coil carriers, convex, for example, a cylindrical, a conical or a truncated conical surface.
  • convex for example, a cylindrical, a conical or a truncated conical surface.
  • the convex surface may also be a flat disk.
  • an axis of the surface, the axis of symmetry of the cylinder, the cone or the truncated cone, coincides with the braid axis of the rotary braiding machine.
  • the at least one closed guiding path can be circular and arranged in a plane perpendicular to the braid axis.
  • the surface of the guiding path can have, for example according to the shape of the surface, a non-zero angle with that plane.
  • the convex surface can be the outer surface of a corresponding body, for example, of a cylinder, a cone or a truncated cone, respectively.
  • the first coil carrier can move on a, viewed from the first coil carriers, concave, for example, a cylindrical, a conical or a truncated conical surface, wherein the further embodiments of this construction correspond to those described above for a convex surface.
  • the concave surface can be the inner surface of a corresponding body, for example, a hollow cylinder, a cone or a truncated cone, respectively.
  • Both of these arrangements for the movement of the first coil carriers have the advantage that the first coil carriers are thereby positioned in the same angle relative to the braid axis, in which the first wires are to impinge on the braid axis. Therefore, another deflection of the first wires is not necessary.
  • the driving of the second coil carriers is, for example, realized as well as for the above described conventional rotary braiding machine, namely by a rigid connection between the second coil carriers and the revolving guiding path.
  • the first coil carrier cannot be rigidly connected to other machine parts to be driven by them, because this rigid connection would collide with the second wires in a complete movement of the second wire around the first coil carrier.
  • the driving of the first coil carrier is, for example, realized just as for a conventional rotary braiding machine, namely by contacting machine components.
  • a driving means which is arranged outside of the at least one first coil carrier, generates without contacting the rotational movement of the at least one first coil carrier around the braid axis.
  • Both the drive means and the at least one first coil carrier can have each at least one magnet, for example, a permanent magnet or an electromagnet.
  • the driving of the at least one first coil carrier is then carried out by a magnetic, non-contact coupling between the magnet in the driving means and the magnet in the first coil carrier over an air gap.
  • the second wire can then be guided through this air gap, if it moves around the first coil carrier.

It can be seen that by the support of the inner gear wheel 41 on the inner gear ring 6 and by the support of the outer gear wheel 42 on the outer gear ring 7 , there is generated an air gap 17 (in the embodiment having a height of about 2 mm) between the housing 44 of the first coil carrier 4 and the pivot mounting 3 , through which the second wire 11 can be guided, as described above.
  • a disk shaped permanent magnet 15 is embedded, its north pole N and its south pole S are oriented perpendicularly to the conical surface of the pivot mounting 3 .
  • the electromagnets 16 are circumferentially arranged on the circumference at regular intervals.
  • the illustration of the permanent magnet 15 and the electromagnet 16 in FIG. 3 is a schematic one only.
  • the permanent magnet 15 it may be used magnet systems with hard magnetic sections and soft magnetic sections and/or with a larger dimensioning in the axial direction of the first coil support 4 as shown in FIG. 3 .
  • the electromagnets 16 form the guiding path of a linear motor, which sets all of the first coil carriers 4 at the same time as a slide into the rotational movement.
  • a rotating magnetic field is generated in the pivot mounting 3 through a corresponding current feed to the electromagnet 16 , which entrains the first coil carriers 4 by a magnetic coupling.
  • the rotating magnetic field moves in the opposite direction of rotation of the pivot mounting 3 .
  • the first coil carriers 4 and the second coil carriers 5 and thus also the first wires 10 and the second wires 11 rotate in opposite directions at the same speed relative to the braiding button 8 , resulting in a uniform and symmetrical mesh formation at the braiding point 8 .
  • FIG. 4 shows a schematic illustration of the roll off movement of the outer gear wheel 42 of the first coil carrier 4 on the outer gear ring 7 , wherein approximately the same illustration would result for an inner gear wheel 41 and the inner gear ring 6 .
  • the trajectory of the second wire 11 upwards or downwards, respectively, to the first coil carrier 4 and thus around the outer gear wheel 42 is also indicated schematically by two dotted lines.
  • the periodically arranged recesses 71 in the single tooth gaps of the outer gear ring 7 into which the second wire 11 can be immersed.
  • Electromagnet coils 16 are illustrated in the inside of the pivot mounting 3 , the electromagnet coils forming a section of the guiding path of the linear motor for the driving the first coil carrier 4 . Due to the arrangement of the outer gear ring 7 on the conical outer surface of the pivot mounting 3 , the linear motor is designed as an external rotor motor.
  • FIG. 5 an alternative embodiment is shown, which does not correspond to the embodiment according to FIGS. 1 to 4 .
  • the pivot mounting 3 has the form of a hollow vertically arranged cylindrical truncated cone, which is tapered towards the top.
  • the supply and the discharge of the material to be braided or of the fabricated meshes, respectively, is done from the bottom to the top.
  • the first coil carriers 4 are arranged inwardly inclined downwards on the inner, conical surface of the pivot mounting 3 .
  • the linear motor is designed as an inner rotor motor.
  • FIG. 5 it is shown the detail of the arrangement of the magnets in the first coil carrier 4 and in the guiding path of the linear motor in the pivot mounting 3 .
  • a plurality of ribs which are individually wrapped with conductive wires to form the coil with an elongated cross section.
  • a permanent magnetic arrangement is mounted on the pivot mounting 3 on its opposite edge, wherein the permanent magnetic arrangement is formed in a horseshoe shape in this case.
  • FIG. 6 a magnetic holding device is shown in FIG. 6 , by means of which a first coil carrier 4 can be secured from sliding below outwards or below inwards, respectively.
  • the magnetic holding device is formed by two identically constructed, horseshoe shaped arrangement of permanent magnets 15 in the first coil carrier 4 or below the surface of the pivot mounting 3 , respectively, which each corresponds to the horseshoe shaped magnet arrangement of FIG. 5 and which are coupled magnetically to each other.
  • the magnetic arrangement which is arranged in the pivot mounting 3 , can be synchronously rotating with the first coil carrier 4 . This can be done most easily, when the magnets in the pivot mounting 3 do not form the fixed guiding path of a linear motor, but are arranged on a rotating rotor 22 as shown in FIGS. 1 and 2 . Since the magnets in this case need not be periodically turned on and off in the pivot mounting 3 , the permanent magnets 15 can also be used for this purpose. As illustrated in FIG.
  • the magnetic arrangement of the permanent magnets 15 which are arranged on the rotatable rotor 22 , then takes over at the same time the function of the rotational driving for the first coil carrier 4 and the holding function against slipping of the first coil carrier 4 , whereby a particularly simple construction is achieved.
