Definitions

  • the invention relates to a braiding, winding or spiraling machine and a method for operating the same.
  • Braiding machines especially rotary braiding machines, can be used to produce hollow tubular braids from a strand material to be processed.
  • a strand is understood to be an elongated, strand-like material, preferably available in almost any length.
  • a strand of the strand can consist of one or more individual strand fibers.
  • a strand fiber can be in particular, but not exclusively, a wire, which can contain iron, but preferably consists of non-ferrous metals, or a textile fiber, a carbon fiber or another strand-like carbon material.
  • a strand fiber can thus be in particular a metal wire, a yarn or a plastic fiber.
  • the number of strand fibers contained in a strand is also referred to as the ply.
  • a strand made of 10 individual wires, for example, has a ply of 10.
  • vascular implants such as stents or vascular prostheses.
  • braiding machines can also be used to braid a strand-like material with a strand, for example to braid a cable with a wire mesh.
  • the strand-like material preferably has a cross-section essentially perpendicular to its longitudinal axis, which is essentially round.
  • the present invention relates to this second application of braiding machines for braiding a strand-like material.
  • Areas of application for braided strand-like materials produced in this way include, for example, electrical cables provided with shielding against electromagnetic fields, cables or hoses provided with protective sheaths against mechanical stress, or molded bodies braided with carbon fibers or other strand-like carbon materials, which may be removed again after the carbon material has hardened, for the production of low-mass components, particularly in lightweight construction.
  • the braided strand material is guided onto a disk with a circumferential groove in the front surface, the so-called pull-off disk, and is then pulled out of the braiding machine.
  • the angle mentioned is defined as an angle between an axis parallel to the longitudinal axis of the strand-like material and half-lines running against the direction of movement of the strand-like material through the point where the strand material hits the strand-like material and the strand material running onto the strand-like material.
  • the braiding angle can, for example, have a value of 50 degrees.
  • Winding machines are similar in function to braiding machines, with the difference that the strands of the strand material to be processed are not woven together, but lie loosely on top of each other or on the strand material to be wrapped. Winding machines can apply one or more winding layers to the strand material to be wrapped.
  • Winding machines are used, for example, to produce cords or ropes, shielding for hoses or cables, or reinforcements for pressure hoses.
  • Spiralizing machines are largely similar in function to winding machines, whereby the strand material to be processed is preferably plastically deformable and therefore forms a self-supporting spiral when wound around the strand material to be wrapped. Spiralizing machines are used, for example, to sheathe cables with copper wires or soft steel wires in the form of a spiral.
  • the invention is described below using the example of a braiding machine for wire as the strand material to be braided and a cable as the strand-like material to be braided, ie for producing a cable surrounded by a wire mesh.
  • this does not represent a limitation; the invention can be used for a braiding, winding or spiraling machine for braiding any strand material with any strand material.
  • Braiding machines of the type described are known from the state of the art.
  • DE 21 62 170 A1 For example, a high-speed braiding machine is known for braiding strand-like material by means of a thread-like strand in the form of wires or strips made of organic or non-organic material using coil carriers which rotate against each other in two parallel planes.
  • the JP S62 66922 A relates to a braiding machine and a braiding method, whereby the braiding angle of a reinforcing material which is braided around a strand-like material - for example a fiber material or a metal wire which is braided around a rubber hose to increase the compressive strength of the latter - can be precisely regulated.
  • the braiding angle should be kept constant so that the stability of the braided strand-like material, for example the rubber hose, does not deteriorate.
  • the diameter of the strand-like material, viewed along its length, is subject to fluctuations. "Diameter” always means a diameter of a cross-section of the strand-like material essentially perpendicular to its longitudinal axis.
  • a problem that can arise from a varying diameter of the strand-like material is an equally varying degree of coverage of the strand-like material by the strand material.
  • the degree of coverage (also referred to as "coverage coefficient”) is defined as a ratio of the total surface area of all strands facing radially outwards with respect to the strand material which cover the strand material in a certain section of the strand material to the surface area of the strand material in this Section. It is assumed that if a strand consists of several strand fibers, the individual strand fibers are laid next to each other and without any gap between them on the strand-like material, so that the strand in the braided state forms a "band" with a certain width on the surface of the strand-like material. The width of this band corresponds to the number of strand fibers in the strand, i.e. the ply, multiplied by the diameter of the individual strand fibers. It is also assumed that all strand fibers in a strand have the same diameter, in particular are even identical.
  • the degree of overlap defined in this way indicates how many strands of strand material in the finished product, i.e. the braided strand-like material, lie on top of each other on average at a certain point on its surface.
  • only a certain part of the braided strands can be taken into account for the degree of coverage.
  • the same number of spools from which the strand-like material is unwound generally rotate in opposite directions.
  • the degree of coverage only the spools rotating in one of the two directions can then be taken into account, i.e. only half the total number of spools used and thus only half the total number of braided strands.
  • a degree of overlap of 1 means that in the braided strand-like material the turns of the individual strands lie (on average) next to each other without gaps on the surface of the strand-like material.
  • a degree of overlap of 0.85 means that in the braided strand-like material there are gaps between the turns of the individual strands, the width of which is on average 0.15 times the width of a strand.
  • a degree of overlap of 1.15 means that in the braided strand-like material the turns of the individual strands overlap on average by 0.15 times their width.
  • a certain degree of coverage is specified for a product to be manufactured, which depends on the required mechanical, electrical or other physical properties or on the required appearance of the desired product, such as its shielding properties or its compressive strength. If the actual degree of coverage of the product is less than the specified value, this can lead to the required properties of the product and thus the required product quality not being achieved. If, on the other hand, the actual degree of coverage of the product is higher than the specified value, this can also lead to quality problems, but in particular to more strand-like material being used during production than necessary, thus making the production costs of the product higher than necessary.
  • the present invention is therefore based on the object of specifying a method for operating a braiding, winding or spiraling machine and a corresponding braiding, winding or spiraling machine in which changes in the diameter of the strand-like material can be taken into account.
  • the at least one strand of material is attached to the strand-like material in a rotationally fixed manner at at least one point.
  • the at least one strand of material is then repeatedly guided around the longitudinal axis of the strand-like material and the strand-like material is simultaneously moved essentially in the direction of its longitudinal axis in the same direction. In this way, the at least one strand of material takes on the shape of a spiral leading around the strand-like material.
  • a diameter of a cross section of the strand-like material is measured essentially perpendicular to its longitudinal axis.
  • a feed rate of the strand-like material and/or a speed at which the at least one strand of material moves around the longitudinal axis of the strand-like material are then controlled or regulated.
  • the feed rate of the strand-like material is the speed at which the strand-like material is always moved essentially in the same direction in the direction of its longitudinal axis.
  • the feed rate of the strand-like material and the rotational speed of the at least one strand of strand material have proven to be the most suitable operating parameters of the braiding machine, via the control or regulation of which changes in the diameter of the strand-like material can be suitably taken into account.
  • the invention allows the feed rate of the strand-like material and/or the speed of the at least one strand to be reduced to such an extent that the risk of strand tears is avoided.
  • a relative feed rate of the strand-like material is controlled or regulated as a function of the measured diameter of the cross section of the strand-like material in such a way that a degree of coverage of the strand-like material by the at least one strand of strand material essentially corresponds to a predetermined value.
  • the relative feed rate of the strand-like material is defined as a distance by which the strand-like material moves around the longitudinal axis of the strand-like material during one complete rotation of the at least one strand of strand material. This distance is also referred to as the pitch or lay length.
  • the degree of coverage of the strand-like material by the at least one strand of strand material has already been defined above.
  • the two drive speeds of the braiding machine are not independent of each other controlled or regulated, but only in relation to one another, whereby a certain relative feed rate of the strand-like material is achieved.
  • This can be done, for example, by controlling or regulating both drive speeds to certain, predetermined values, the ratio of which results in the desired relative speed.
  • the predetermined values of the two drive speeds are preferably selected such that neither of the two drive speeds exceeds the respective permissible maximum speed.
  • the desired relative speed can also be achieved by maintaining the current value of one of the two drive speeds and changing the value of the other drive speed until the ratio of the two drive speeds results in the desired relative speed.
  • This embodiment of the invention is based on the observation that the degree of coverage can be expressed precisely by the above-mentioned relative speed and the diameter of the strand-like material (as well as several constant factors).
  • a "development" of the surface of the strand-like material 7 is considered on a section which has a length corresponding to the distance by which the strand-like material moves around the strand-like material 9 during one revolution of the strand material, ie a rectangular development of the surface of the strand-like material (in Fig. 1 heavily outlined) with height h, width ⁇ ⁇ D and thus area h ⁇ ⁇ D.
  • a rectangular surface of a section of the "band" formed by a strand of material 9 with a width S and a height b and thus the area b S is wound onto this rectangular development of the strand-like material.
  • the rectangular surface of the strand of material 9 does not lie exactly on the rectangular development of the strand-like material, but the two rectangular surfaces overlap each other. However, these overlaps compensate each other so that the ratio defining the degree of overlap corresponds exactly to the ratio of the areas of the two rectangular surfaces.
  • the relationship just mentioned is used to control or regulate the relative feed rate of the strand-like material.
  • the measured diameter D, the predetermined degree of coverage k and the constants f, X and d are known, from which the relative feed rate h of the strand-like material can be calculated and used as a target value for the control or regulation of the braiding machine.

  • the braiding angle defined above is additionally measured and used to control or regulate the relative feed rate of the strand-like material.
  • the control or regulation of the relative feed rate of the strand-like material can be carried out in such a way that a target value for the braiding angle is determined and by changing the relative feed rate while simultaneously measuring the braiding angle, the braiding angle is also changed until it has reached its target value.

  • the invention further relates to a braiding, winding or spiraling machine which is designed to be operated according to a method according to the invention for braiding, winding or spiraling a strand-like material, in particular a cable, with at least one strand of material made of at least one strand of material, in particular of at least one wire, and which is designed to repeatedly guide the at least one strand of material around the longitudinal axis of the strand-like material and to simultaneously move the strand-like material essentially in the direction of its longitudinal axis always in the same direction.
