Definitions

  • the invention relates to a device for processing a hollow cylinder according to the preamble of patent claim 1.
  • Such a device has already been proposed in European Patent Application No. 94 101 572.9.
  • This device has a machine bed, on which two bearing devices are supported, which serve for the rotary accommodation of a hollow cylinder via its end faces.
  • the device also includes a gas supply device for supplying a gas flow into the hollow cylinder in order to inflate it by a suitable internal pressure so that it has a circular cross section.
  • the gas for example air, can flow into one of the end faces of the hollow cylinder.
  • An optical slide is also attached to the machine bed and can be displaced along the longitudinal direction of the hollow cylinder in order to act on the outer lateral surface of the hollow cylinder for processing by means of a suitable radiation.
  • the optical carriage can carry a deflecting mirror in order to deflect a laser beam that is brought in parallel to the hollow cylinder in the direction of the surface of the hollow cylinder.
  • a laser can also be attached directly to the optical slide, which is then carried along with the optical slide. The laser beam leaving the laser can strike the surface of the hollow cylinder directly or can be deflected in a corresponding manner by a deflecting mirror likewise arranged on the optical slide.
  • the invention has for its object to provide a device of the type mentioned, with which very precise patterns can be produced by irradiation on the surface of the hollow cylinder even if there are high pressures inside the hollow cylinder and the machine bed is less stable.
  • a device according to the invention is characterized in that it has a sealing piston which lies in the interior of the hollow cylinder and is coupled to the bearing device on the side of the gas supply device via at least one strand-shaped element.
  • the sealing piston lying in the interior of the hollow cylinder prevents pressurization of the bearing device of the hollow cylinder which lies on the side of the sealing piston facing away from the gas supply device.
  • essentially equal forces act in opposite directions on the sealing piston and on the bearing device on the side of the gas supply device, but due to the strand-like element, the compressive force acting on the sealing piston is transmitted to the bearing device on the gas supply device. so that the forces acting on this bearing direction practically cancel each other out.
  • the result of this is that the two bearing devices for the hollow cylinder can no longer be pushed away from one another, and consequently the machine bed can no longer bulge in the central region between the bearing devices.
  • a more precise production of patterns on the surface of the hollow cylinder using the optical device attached to the machine bed is thus possible.
  • a tailstock or a headstock can be understood here as a storage device.
  • the sealing piston and the gas supply-side bearing device are coupled to one another in such a way that, as far as possible, no transverse forces are transmitted from the sealing piston to this bearing device.
  • a longitudinal element running along the longitudinal axis of the hollow cylinder can be provided.
  • This strand-like element is preferably a rope that can be wound onto a rope drum that is firmly connected to the bearing device, wherein the rope can also be guided to the rope drum via deflection rollers.
  • the sealing piston can thus move the sealing piston in a simple manner along the longitudinal direction of the cylinder, namely away from the gas supply-side bearing device with appropriate tracking of the rope and using the pressure inside the hollow cylinder and to the gas supply-side bearing device while winding the rope onto the rope drum.
  • the displacement of the sealing piston can also take place under the control of a stepper motor.
  • the sealing piston is preferably displaced to almost the bearing device of the hollow cylinder opposite the gas supply-side bearing device, namely by the acting pressure force and corresponding adjustment of the cable, without the sealing piston coming into contact with the bearing device mentioned.
  • the hollow cylinder can be inflated over the largest possible area of its length in order to obtain a circular cross section.
  • the pressure piston can advance so that the cylinder space remaining between it and the gas supply-side bearing device either remains completely closed or is only opened through a few through holes, so that the hollow cylinder is inflated no such powerful gas pressure generator is needed.
  • the sealing piston can move synchronously with the longitudinal movement of the optical device.
  • the irradiation of the hollow cylinder can be in front of or behind the Sealing piston or in the area of the sealing piston.
  • the sealing piston is seated on ball bearings on a central tie rod connected to the strand-like element. This is advantageous in that only the sealing piston now rotates with the cylinder, but twisting of the strand-like element is avoided.
  • the bearing device for the hollow cylinder on the side of the gas supply device is provided with a receptacle for the sealing piston. If the sealing piston is completely guided to the gas supply-side bearing device, it runs onto the receptacle and is pulled against it with the aid of the strand-like element, so that it also sits securely on the receptacle. The sealing piston therefore remains connected to this bearing device, even if the hollow cylinder is removed.
  • an axial fan As a gas supply device, for. B. an axial fan are used, which is arranged coaxially to the bearing device for the hollow cylinder, or a nozzle which sits inside the bearing device for the hollow cylinder and is connected to an external pressure gas generator, for. B. with an external compressed air network.
  • the hollow cylinders mentioned can be those which are suitable for producing screen printing stencils which can be used in particular for printing on textiles or other suitable materials. This also applies if the halftone technique is affected.
  • a hollow cylinder can thus be constructed from a uniformly perforated or perforated, thin metal foil, which usually consists of nickel. Their wall thickness is approximately 0.09 mm.
  • the holes in the metal foil are closed by a lacquer layer on the outer surface of the hollow cylinder.
  • this lacquer layer can be removed again in certain areas, so that corresponding holes in the metal foil are again exposed in accordance with the desired pattern.
  • this can be removed in different ways, for example by burning off when laser radiation is incident or by exposure with the aid of laser radiation and subsequent development.
  • the lacquer layer If the lacquer layer is to be removed by exposure and development, it must be polymerizable by light. In general, existing double bonds in the lacquer layer are broken up and these react with adjacent chain molecules of the lacquer or the resin, because there have been double bonds broken in the same way. There is a crosslinking and thus hardening, which is usually associated with a volume shrinkage. Crosslinking also achieves higher chemical resistance.
  • the latter is used to remove the unexposed and therefore less resistant resin areas from the lacquer layer in the subsequent development step.
  • a double layer of lacquer can also be used instead of a single layer of lacquer.
  • the layer lying directly on the cylindrically shaped metal foil is a more light-absorbing layer. Their strong light absorption can be brought about by adding higher doses of a light-absorbing dye to the resin matrix. Over this more absorbent layer is another layer, which is kept largely transparent and which generally also contains a higher dose of a sensitizer.
  • complete transparency of this second layer is not possible because irradiation, which is intended to bring about crosslinking, requires the trapping of light quanta by the resin. This capture process triggers precisely those photochemical processes that ultimately lead to cross-linking.
  • the double-layer technique is of advantage if, in particular, fine and sharp contours are to be created.
  • the layer of dyestuff underneath prevents the diffuse light backscattering effect that leads to broadening of the contours due to the metallic surface of the underlying metal foil.
  • the two different layers required in this variant are applied one after the other, each of which is first dried after application of one of the layers.
  • a die can also be used as the hollow cylinder, the surface of which can be structured in a suitable manner, in order then to be able to produce a perforated metal cylinder of the type described above. This does not necessarily have to be evenly perforated.
  • a hollow cylindrical die generally consists of a thin sheet of metal that is not provided with a sealing structure. There is a light sensitive on the outer surface of this metallic cylinder Layer system that z. B. can be built up from a single layer of lacquer or from a double layer of lacquer, as already described above.
  • the die To process the die, it is picked up on the two ends by a round engraving machine through two truncated cones, a pattern image being provided to the photosensitive lacquer by a laser beam.
  • the paint can be removed completely by thermal detachment using a laser beam of the appropriate intensity and wavelength (e.g. CO 2 gas laser with a wavelength of 10.6 ⁇ m).
  • the lacquer can also be removed by photolithographic detachment, usually with a laser wavelength in the range from 320 nm to 550 nm. In photolithographic detachment, the crosslinking of the polymerizable lacquer layer by light and a subsequent development process are again carried out.
  • a metal layer is applied galvanically to the surface of the structure thus obtained, for example a nickel layer in a nickel-plating process in a galvanic and sometimes also in a chemical nickel bath.
  • Nickel is now deposited on the bare metal areas of the die.
  • a nickel cylinder with a desired perforation is obtained, which is then removed from the die. If this nickel cylinder has a uniform perforation, it can be the cylinder already mentioned at the beginning.
  • the structure of the perforation can also be selected in a different way by appropriate processing of the die, for example to obtain a halftone engraving.
  • FIG 1 the basic forces are shown, which when filling a hollow cylinder 1 with a compressed gas, for. B. compressed air, act on headstock 2, tailstock 3 and machine bed 4 and also the resulting deformations.
  • a pressure force acts on the tailstock 3 and the headstock 2 of a laser engraver, in which the headstock 2 and tailstock 3 are fastened to the machine bed 4, if the latter has an increased pressure in relation to the environment.
  • the tailstock 3 can be moved on guides relative to the headstock 2 in order to accommodate hollow cylinders 1 of different lengths. In the working state, there is also a fixed connection between the tailstock 3 and the machine bed 4.
  • the line of action of the resulting compressive forces coincides with the axis of rotation 5 of the hollow cylinder 1.
  • the headstock end 6 of the hollow cylinder 1 is closed by a truncated cone-shaped receptacle 7 which can be driven by a drive shaft 8 mounted in the headstock 2, it can be seen immediately that the magnitude of the compressive force is the product of the internal pressure built up in the hollow cylinder 1 and the internal cross section of the hollow cylinder 1 corresponds.
  • the resultant of all the compressive forces passes through the center of gravity of the inner cross section of the hollow cylinder 1 and thus the effectiveness of the resulting compressive force coincides with the axis of rotation 5 of the hollow cylinder 1.
  • This moving bearing 11 On the tailstock 3 there is also a rotating bearing 11 which carries the other end of the hollow cylinder 1.
  • This moving bearing 11 is ring-shaped and has a central inner channel through which air is blown into the interior of the hollow cylinder 1.
  • the internal pressure required to produce a largely circular shape must be greater the greater the wall thickness of the hollow cylinder 1 to be clamped. Since a die is used for the later galvanoplastic production of stencils and is subject to various stresses, e.g. B. the exposure to lead due to the hydrostatic buoyancy forces in the electroplating bath, the wall thickness is usually greater than that of a screen printing stencil (about two to three times). Accordingly, higher pressures must be used when rounding out a die than with a stencil.
  • a bending moment acts on the machine bed 4, which is the product of the total pressure force acting on the tailstock or headstock and the distance 12 between the axis of rotation 5 of the hollow cylinder and the axis of gravity 13 of the cross section of the machine bed 4 results.
  • This lead moment causes the machine bed 4 to bend upwards in the area between the headstock 2 and tailstock 3.
  • the guides provided on the machine bed 4 for an engraving slide or optical slide which is no longer shown here, are in one relative to the axis of rotation 5 of the hollow cylinder 1 and thus to the jacket generators of the hollow cylinder 1 in the case of fine engraving tents, the size is often noticeably curved.
  • the hollow cylinder 1 is now equipped in its interior with a sealing piston 14 which can be displaced in the axial direction.
  • the force in the strand-like element 15, here the rope force 16 acts on the tailstock 3 as a tensile force and is of the same magnitude and directed in the opposite direction to the sum of all the compressive forces 17 which act on the tailstock 3. It is essential for this that no transverse forces are transmitted to the tailstock 3 via the strand-like element 15 or the rope.
  • the strand-like element 15 or rope can run at least approximately in the direction and position of the axis of rotation 5 of the hollow cylinder 1, in order then to be guided around a first deflecting roller 18 and a second deflecting roller 19 and wound onto a rope drum 20 or unwound therefrom .
  • the course of the strand-shaped element 15 can also deviate somewhat from the position of the axis of rotation 5, which depends on the design and the rigidity of the machine bed 4, since curvatures of the machine bed 4 are not noticeable in the engraving image until they exceed a certain limit.
  • the compressive force acting on the sealing piston 14 is designated by the reference numeral 21, while the bearing 11 also has an end receptacle 22 for receiving the sealing piston 14 when it has been completely pulled to the tailstock 3. If the hollow cylinder 1 is removed from the device, the sealing piston 14 then remains seated on the receptacle 22 of the bearing 11.
  • FIG. 3 shows the overall view of a device according to the invention in a perspective view. It designates 23 a thin hollow cylinder, which represents a die coated with lacquer or a circular screen coated with lacquer.
  • This hollow cylinder 23 is supported at its two open ends, namely that it engages at its tailstock end a support cone 25 and at its headstock end a support cone 26.
  • a rotary drive is provided in the headstock 27 for initiating a rotary movement in the hollow cylinder 23.
  • Air is introduced into the interior of the hollow cylinder 23 via a hollow shaft 28 in the tailstock 29, the pressure of which has been increased somewhat in a suitable manner compared to the ambient pressure. For the application of this air z. B.
  • a radial fan 30 is provided, which leads the compressed air to the hollow shaft 28 via an air line 31.
  • a carriage 32 is moved in the axial direction of the hollow cylinder 23 while the hollow cylinder 23 is rotating.
  • a traveling solid-state laser 24 is provided on the slide 32, which is switched on or off in time with the pattern information, the beam of which strikes the hollow cylinder 23 via a deflection mirror 24a.
  • the carriage is driven by a spindle 33 with a stepper motor 34 flanged on.
  • Guides 35 attached to the machine bed 4 are responsible for the exact parallel guidance of the slide 32.
  • the computer 36 transmits the step pulses to the stepper motor 34 and the switch-on and switch-off commands to the solid-state laser via a control unit (not shown) 24th
  • the tailstock 29 can be moved in the longitudinal direction of the hollow cylinder 23 and is arranged on guides 39 for this purpose. In this way, the position of the tailstock 29 can be adapted to different lengths of the hollow cylinder 23 and, moreover, the tailstock 29 can be moved away from it to replace the hollow cylinder 23, so that the hollow cylinder 23 can be removed in a simple manner backwards from the machine.
  • the tailstock 29 consists of a base plate 67 which is connected to an end plate 40 and a sheet metal jacket 66 which covers the tailstock 29 to the outside, so that the construction is as rigid as possible.
  • a rigid bearing sleeve 41 is fastened to the end plate 40 by means of screws 42. This carries ball bearings 43 through a Pressure ring 44 and a sleeve 45 are spaced and pressed by a lock nut 46 against a collar 47 of the bearing sleeve 41.
  • the ball bearings 43 carry a rotatable support sleeve 48.
  • a ring 49 secures the support sleeve 48 against axial displacement.
  • the interchangeable support cone 25 is seated on the support sleeve 48 and is pressed against a collar of the support sleeve 48 via a spacer sleeve 51 and a lock nut 50.
  • the support cone 25 is exchangeable so that it can be exchanged for another size if a hollow cylinder 23 with a different inside diameter has to be clamped.
  • In the interior 52 of the hollow cylinder 23 there is an increased air pressure which is applied by the axial fan 53. This pressure is increased by about 5 to 50 mbar compared to the normal ambient pressure, although the higher pressures can no longer be generated by axial fans.
  • a sealing ring 72 is provided so that no air can escape from the interior 52 through the ball bearings 43.
  • the cable drum 59 sits together with a worm wheel 62 on a shaft 61 which is supported in a bearing structure 65.
  • a worm 63 which is connected to the stepper motor 64, drives the worm wheel 62.
  • the rope groove of the deflection roller 58 is correspondingly deep.
  • the axial fan 53 is held by struts 54 on a mounting ring 55, and the mounting ring 55 is mounted on the end plate 40 by means of screws.
  • the axial fan 53 can also be designed as a multi-stage fan if the pressures to be generated have to be higher.
  • the pressure in the interior 52 and the longitudinal force in the rope 56 act on the tailstock 29.
  • the pressure and the longitudinal rope force cancel each other out, so that these forces only elastically deform the tailstock 29, but not the machine bed.
  • the elastic displacements of the hollow cylinder 23 are kept small and a very precise engraving is made possible.
  • FIG. 1 A somewhat different embodiment of the construction of the tailstock 29 is shown in FIG.
  • the application of the pressure in the interior 52 takes place here by a connection to an external compressed air network. Air is fed from this network via a flexible line 68 and via pressure reducers and filters, which are no longer shown, to a nozzle 69 in the end plate 40 and is discharged into the interior 52.
  • the rope 56 is guided through a centrally located slot 70 and in turn wound up or unwound by the rope drum 59.
  • the cable drum 59 is driven here by the stepper motor 64 via a spur gear 71.
  • a retaining ring 73 is provided in order to take over the sealing piston when it has arrived in its end position and has been pulled up to the tailstock 29 by the rope 56.
  • the retaining ring 73 (receptacle) is firmly seated on the free end of the support sleeve 48.
  • the sealing piston 74 already mentioned is shown in FIG.
  • This sealing piston 74 consists of an exchangeable receiving ring 75 arranged on the left, a very thin and light middle ring 76 and a ring cap 77 positioned on the right.
  • This ring construction must correspond to the respective size of the hollow cylinder 23; it is therefore releasably held on the central bearing housing 78 by screws 79.
  • This central bearing housing 78 rotates with the ring construction and the hollow cylinder 23 and is therefore supported via ball bearings 80 against a tie rod 81 which can no longer be rotated.
  • a sealing ring 82 ensures that as far as possible no air can escape from the interior 52, which is under increased pressure.
  • the sealing piston 74 can also be used if the hollow cylinder 23 is an already perforated circular sieve and the engraving thereof is carried out by removing a layer of lacquer which lies on the outside of its outer surface. In this case, the openings of the circular sieve are exposed and without sealing piston 74 a lot of air would escape and a high compression performance would have to be applied.
  • the engraving work then begins on the side of the headstock 27. As the engraving head 32, 24, 24a advances in the direction of the tailstock 29, ever larger parts of the circular screen 23 are exposed. Approximately synchronously with this advance, the sealing piston 74 is also moved inside the circular sieve 23.
  • the sealing piston 74 is also used if no leakage points occur during the engraving of a circular screen. This is the case if the effect of the serious laser radiation crosslinks the lacquer layer but does not remove it and the non-crosslinked lacquer layer is only removed in a later work step (development process). The positional accuracy of the engraved image is no longer influenced by this working process. This manufacturing process is more expensive, but it is often used for fine engravings because the one that can be used here shorter wavelength of the laser radiation enables smaller focus diameters. However, higher concentricity is also necessary here. This can be achieved by filling the interior with pressure.
  • FIG. 8 shows the design of the headstock 27 when the supply of air with higher pressure to the interior 52 of the hollow cylinder 23 is to take place from the side of the headstock 27.
  • a shaft 83 driving the hollow cylinder 23 is designed as a hollow shaft and is rotatably supported in the headstock box 91 via ball bearings 43.
  • a toothed belt wheel 85 is seated on the drive shaft 83 and firmly connected to it. The toothed belt 86 engages in this. Flanged wheels 87 prevent the toothed belt 86 from sliding sideways.
  • the end plate 40 carries an annular bearing housing 95 for holding the right-hand ball bearing 43. This bearing 43 is held there axially by a locking washer 96.
  • An impeller 84 runs in the free interior of the drive shaft 83 and ensures the increased pressure in the interior 52.
  • This fan wheel 84 sits together with a V-belt pulley 93 on a bell shaft 92.
  • a V-belt 94 drives the bell shaft 92 and the fan wheel 84.
  • the cable 56 which holds or moves the sealing piston 74, is guided through the bell shaft 92 to a deflection roller 57 and from there in a known manner to a cable drum 59 which is driven in the same way as that in FIGS. 4 and 5 .
  • the bell shaft 92 is supported by means of two ball bearings 43 on a hollow axle stub 88, in which the deflection roller 57 is supported via the axle 89.
  • the hollow axle stub 88 is firmly connected to the left rare plate 90 of the headstock box 91. Otherwise, the same elements as in Figures 4 and 5 are provided with the same reference numerals and will not be explained again.
