Definitions
- the invention relates to a method for cutting textiles, which consist of plastic fibers or have a proportion of plastic fibers, by means of a laser beam according to a predetermined cutting pattern. Furthermore, the invention relates to a cutting device for performing the method. Finally, the invention relates to a cutting system for cutting textiles by means of such cutting devices. In particular, the present invention relates to the cutting of airbag materials that can be coated or uncoated.
- Textiles of this type which can be made of polyamide, polyester or polyethylene, for example, or have a proportion of such synthetic fibers, are cut in high-layer cutters in order to achieve a high output.
- Layers of the material to be cut for example airbag material, and foils are first placed alternately on top of each other.
- the up to 20 layers lying one above the other are then fed to the laser cutting system and cut in the laser cutting system by means of a laser beam.
- the film intermediate layers are necessary after otherwise adjacent layers of the textile material would weld together at the cut edges due to the plastic fibers or the plastic fiber portion.
- An alternative to cutting textiles using high-layer cutters is cutting on a single-layer cutter.
- this is a plotter that moves a laser cutting head in the X and Y directions.
- the advantages of a single-layer cutter can be seen in the fact that no intermediate layers are required here and the textile material is also relatively flat, which leads to better cutting results and higher accuracy compared to the high-layer cutter.
- a disadvantage of single-layer cutters is the low working speed. Very fast plotters have a maximum working speed of 2 m / sec with an acceleration of 1.5 g and are therefore not a real alternative to the high-position cutter in terms of the output volume.
- the invention is therefore essentially based on the object of creating a cutting system for cutting textiles which are made of plastic or have a proportion of plastics by means of a laser beam, which has the basic advantages of a single-layer cutter, but which on the other hand has very high cutting speeds allowed.
- a preferably fixed laser beam is widened, deflected according to the cutting pattern to be generated and focused on the textile to be cut.
- the cutting device for carrying out the method according to the invention, it contains the following: a laser source for generating a laser beam, an expansion lens for expanding the laser beam generated in the laser source, a motor-driven deflection mirror device for deflecting the expanded laser beam in accordance with the one to be generated Cutting pattern, a motor-driven focusing device for focusing the laser beam on the plane of the textile to be cut depending on the deflection of the laser beam, and a control device for controlling the operation of the cutting device.
- the focusing can be realized in that the expansion optics are equipped with a variable focal length, for which purpose a lens or lens group of the expansion optics can be motor-displaceable in the direction of the laser beam.
- the deflecting mirror device can comprise two deflecting mirrors which can be pivoted in two mutually perpendicular planes, a galvanometer scanner preferably being provided for pivoting each deflecting mirror.
- the laser beam serving as a cutting tool is thus focused on the tissue by the laser beam source via the expansion optics and two subsequent galvanometer scanners, the expansion optics being equipped with a variable focal length, which ensures that when the laser beam is deflected via the Galvanometer- Scanner the focal point of the laser beam is always on the cutting plane.
- the textile material can be cut from the roll, as a result of which, in comparison to the high-layer cutters, in which the length of the layers is predetermined by the laying machine used to lay the layers possible nesting of the cuts results in optimal use of the fabric.
- a cutting system for cutting textiles which has at least two cutting devices according to the invention, a common control device being provided for the at least two cutting devices and the at least two cutting devices being arranged and controllable in such a way that immediately adjacent areas of the to be cut Textiles can be cut.
- FIG. 1 is a perspective view of the cutting device according to the invention
- Fig. 2 is a front view of a cutting system according to the invention with two cutting devices
- FIG. 3 shows a side view of the cutting system according to FIG. 2.
- the cutting device sketched there is designated overall by the reference number 20 and the textile material to be cut is designated by the reference number 30.
- the cutting device 20 comprises a fixed laser 22, which generates a laser beam 24.
- the laser beam 24 first passes through an expansion lens 26 in which the laser beam 24 is expanded.
- the expanded laser beam 24 ' is then successively reflected on two mirrors 28, 29 which then direct the laser beam onto the textile material 30 to be cut in accordance with a predetermined cutting pattern.
- the deflecting mirror 28 can be pivoted in a plane parallel to the plane of the textile material 30 and the deflecting mirror 29 can be pivoted in a plane that is perpendicular to the plane of the textile material 30.
- the galvanometer scanners 32, 34 are controlled by a control device (not shown) in such a way that the laser beam 24 'on the textile material 30 generates the cut according to a predetermined cutting pattern. For this it is necessary that the laser beam 24, 24 'is focused on the plane of the fabric 30.
- the laser beam moves on the textile material 30 he ordered to continuously refocus the laser beam.
- the expansion optics 26 are equipped with a variable focal length, the lens 36 of the expansion optics 26 being motor-displaceable in the direction of the laser beam; the above-mentioned control, not shown, takes over the control of the lens shift in order to maintain exact focusing.
- the laser beam has a working area of approximately 200 mm x 200 mm to approximately 1,500 mm x 1,500 mm.
- a laser power in the range of approximately 500 watts to approximately 3,000 watts, for example, airbag material can be cut at very high speeds, that is to say at speeds of up to approximately 7 m / sec.
- the cutting system comprises a feed station 40, from which ribbon-shaped textile material 42 is unwound from a supply roll 44, a cutting station 46, in which the ribbon-shaped material is cut by means of laser beams in accordance with the predetermined cutting pattern and which is covered by a radiation protection housing 54, and a removal station 48, in which the cut parts are removed or transported away on a conveyor belt or a conveyor 52.
- the band-shaped textile material 42 has a width of 3 m.
- two laser cutting devices are arranged side by side.
- the laser beams emerging from the laser sources 22 meet, after they have passed through the expansion optics and after deflection via suitable mirrors, to the respective scanner device 25, which in each case comprises the two galvanometer scanners 32, 34 together with mirrors 28, 29. From here, the two laser beams are deflected into the cutting plane 50 onto the textile web according to the predetermined pattern, whereby they are focused in the plane 50. As can be seen from FIG. 2, the two scanner arrangements 25 are arranged next to one another transversely to the fabric web 42 and are capable of processing half the width of the web in each case.
- the web of fabric can be transported through the cutting station either step by step, so that when the web of fabric is at a standstill, or continuously, so that the web of web is cut in one pass. In the latter case, the system is particularly compact.
- contour cuts with a maximum width of 3000 mm and with a practically unlimited length are possible.
