Definitions

  • the invention relates to a method for cutting textile material by means of laser radiation, wherein the laser radiation is directed by means of a cutting optics on the textile material and wherein the textile material is cut by a relative movement of the cutting optics to the textile material along a predetermined cutting line.
  • the invention further relates to a system for cutting textile material by means of laser radiation, with a source for the laser radiation, with a cutting optics and a device for generating a relative movement of the cutting optics to the textile material along a predetermined cutting line.
  • the material When cutting materials by means of laser radiation, the material is removed by the laser radiation in the area of a cutting line. In this case, the material to be removed is strongly heated and thereby melted and / or vaporized and / or burned depending on the nature of the material. Gas, mist or smoke-like waste products are produced in most materials. These waste products are extracted by plants and processes according to the prior art.
  • the font JP-H04-356386A shows a plant for cutting textile material, in which steam is applied in the region of the cutting line on the textile material.
  • the font US3679863 shows a plant for cutting material, in which a gas stream enveloping the laser beam is mixed with fine water mist to cool the material to be cut in the region of the cutting line.
  • the object of the invention is to provide methods and equipment for cutting textile materials by means of laser radiation, in which an odor load of the textile material to be cut is significantly reduced.
  • the invention has recognized that the waste products of cutting, especially in the case of textiles, are distributed in the tissue shortly after the cut by diffusion and are deposited on the fibers over a large area. Therefore, the first few seconds after the cut are crucial to effectively combat the odor burden. By applying an odor-reducing treatment agent in this period, therefore, a particularly large effect can be achieved. At the same time, the waste products have not yet spread, so that the use of the treatment agent can be limited to the area of the cutting line.
  • the odor reducing treatment agent is a fluid. Fluids are procedurally particularly easy to handle and can be particularly well introduced especially in textile materials.
  • the treatment agent contains water vapor. It has been shown that can be dispensed with by the shortly after the cut after treatment mostly chemical cleaning agents. In most cases, such detergents can be dispensed with completely. Steam can be provided particularly cheap and is at the same time particularly environmentally friendly.
  • the treatment agent is applied via a nozzle.
  • the system according to the invention is preferably further developed in such a way that the device for applying an odor-reducing treatment agent to the textile material comprises a nozzle.
  • the treatment agent can be particularly simple and targeted to the cutting line.
  • the device for generating a relative movement of the cutting optics to the textile material on a table and along two axes parallel to the table plane movable first processing head, which receives the cutting optics Through this design arbitrarily designed cutting lines can be traversed easily and precisely.
  • the nozzle and the cutting optics are moved together along the cutting line.
  • the system according to the invention is preferably further developed in that the nozzle is arranged on the first machining head.
  • the nozzle is arranged on the first processing head, that the treatment agent is discharged in the direction of a point on the table, which is offset from the focus of the cutting optics.
  • the time between cutting and application can be controlled by varying the speed of movement of the machining head.
  • the system is further developed in that the nozzle is arranged pivotably about an axis perpendicular to the plane of the table through the focus of the cutting optic extending axis of the machining head.
  • this comprises a device for providing the treatment agent.
  • the device for providing the treatment agent comprises a steam generator.
  • FIG. 1 is a plant 1 for cutting textile materials by means of laser radiation shown schematically according to the invention.
  • a safety panel of the system is omitted for clarity.
  • the system 1 consists of a table 2 on which a carriage 3 is arranged to be movable in a direction represented by the double arrow 4.
  • the carriage 3 carries a machining head 5, which in turn is movably arranged on the carriage 3 in a direction represented by the double arrow 6.
  • the system 1 has a laser beam source 7 which generates the laser radiation required for cutting a textile material 8.
  • the laser radiation passes along a first beam path section 9 to a first beam deflection 10 and from there along a second beam path section 11 to the machining head 5.
  • the processing head 5 carries a cutting optic 12 which images the beam onto a focus 13 at which the textile material 8 is cut.
  • the movement of the carriage 3 and the machining head 5 is carried out in a known manner, e.g. by means not shown spindle drives.
  • a control also not shown activates this spindle drives so that the machining head 5 and thus the focus 13 is guided along a predetermined cutting line 14.
  • the textile material 8 is cut at this cutting line 14 by the laser beam.
  • the table In order to remove waste products generated during cutting, the table is provided with a large-scale suction, not shown.
  • a nozzle 15 is arranged on the machining head 5, through which an odor-reducing treatment agent 16 in the region of the cutting line 14 is applied to the textile material 8.
  • the treatment material 16 is, for example, water vapor, which is supplied by a steam generator 17 via a hose 18 of the nozzle 15.
  • odor-binding additives may be added to the steam in the steam generator 17.
  • odor-binding additives e.g. Triethylene glycol or cyclodextrin derivatives known from commercial odor neutralizers.
  • Triethylene glycol or cyclodextrin derivatives known from commercial odor neutralizers.
  • water vapor and ethanol vapor into consideration.
  • FIG. 2 the machining head 5 of Appendix 1 is shown in more detail.
  • the cutting optics 12 is fixed, with only the housing of the cutting optics 12 can be seen.
  • the optical design of the cutting optics 12 corresponds to the known structure of cutting optics in laser cutting systems and therefore requires no further explanation.
  • the cutting optics 12 is rotatably attached to the machining head about its optical axis.
  • a ring gear 20 is fixed, which meshes with a pinion 21, which is driven by a rotary motor 22.
  • slip rings 23, 24 are arranged on the cutting optics, of which the slip ring 23 is rotatably connected to the cutting optics 12, while the slip ring 24 is rotatably supported by a bearing 25 relative to the cutting optics 12.
  • the slip rings 23, 24 each have a ring channel 26, 27 open towards the other slip ring.
  • a connecting piece 28 is arranged, which is connected via a bore with the annular channel 27.
  • the nozzle 15 is connected via a bore with the annular channel 26.
  • the odor-reducing treatment agent 16 is supplied via the hose 18 and the connecting piece 28 to the annular channel 27 and passes from there via the annular channel 26 into the nozzle 15, from where it is discharged.
  • the nozzle 15 is shaped so that the treatment medium 16 is delivered as a simple spray cone.
  • Other Designs are also conceivable, such as slit-shaped or crescent-shaped nozzles.
  • the processing optics 12 is rotated together with the slip ring 23 and the nozzle 15 about the optical axis of the cutting optics 12, while the delivery point of the treatment agent 16 pivots about the focus 13 of the cutting optics 12. This remains a distance 29 between the discharge point the treatment agent 16 and the focus 13 of the cutting optics 12 constant.
  • the carriage 3, the treatment head 5 and the rotary motor 22 are controlled so that on the one hand the focus 13 of the cutting optics 12 along the cutting line 14 along and on the other hand, the delivery point of the treatment agent 16 is guided along the cutting line ,
