Definitions

  • the invention relates to a system for irradiating a Workpiece with ultraviolet radiation with at least a UV radiation source and at least one Transport device, wherein the workpiece from a loading point the system by means of the transport device can be supplied to and from a radiation zone can be transported to an extraction point of the system is, with the system a common loading and Has removal point and the workpiece between the common loading and unloading point and the Irradiation zone is movable back and forth.
  • Equipment for irradiating a workpiece with ultraviolet Radiation comes, for example, during manufacture of interior fittings for motor vehicles. These are usually usually transparent Paint or resin layer to provide a to produce a shiny and durable surface.
  • the lacquer layer can be applied by that the interior fitting to be coated, for example a molded wood part, in particular a veneer part, so positioned on a wall of a molded part is that between the wall and the one to be coated Surface of the interior fitting Gap is formed, which is then filled with liquid when exposed to ultraviolet radiation filling hardening surface coating material can be. The curing then takes place in such a way that the interior fitting in a facility for radiation is introduced with ultraviolet radiation.
  • the Workpiece in the form of the interior component is then by means of a transport device for an irradiation zone, d. H. the radiation field of a UV radiation source, where it is irradiated with the ultraviolet radiation becomes.
  • the workpiece then becomes one Irradiation facility's tapping point transported where it can be taken from the system.
  • a disadvantage of such a construction is, however, that usually to operate such a system multiple people are required.
  • EP-A-0 501 551 is a system for successive Processing of workpieces known in the on a Rotary table four supports for one workpiece each are arranged.
  • the turntable can rotate be displaced, the carrier with the attached to it Workpieces based on a loading and Tapping point three different workstations one after the other can be fed to subsequently to return to the loading and unloading point.
  • One of the work stations is a UV radiation zone educated. Irradiating a workpiece using such a system has proven to be time consuming.
  • the object of the present invention is a system of the type mentioned in such a way that it enables simplified operation, being within UV radiation of a workpiece in a shorter time can be carried out.
  • the system at least two carriers each for holding a workpiece comprises, which can be positioned on the transport device and which alternate between the loading and removal point and the radiation zone are reciprocable.
  • Such an embodiment has the advantage that Workpiece from the same side of the system from the radiation zone feedable and after irradiation the system is removable. The loading and unloading of the workpiece can thus be done by the same operator be performed.
  • This has additional the advantage that the person who is still unirradiated Workpiece feeds the system, the result of the irradiation can control itself and, if necessary, the Irradiation parameters of the system for subsequent workpieces change if the radiation result is unsatisfactory can.
  • the operator can not only for loading the system and removing the workpieces be used, but also in addition to Checking the work result and setting the Coating plant.
  • the configuration according to the invention also has the Advantage that the system is very compact as a single workstation can be trained. With mass production can several such individual jobs for Use, so that even in the event of a failure of a The entire production to a standstill comes, but at other workplaces without interruption other workpieces can be irradiated.
  • the carriers used according to the invention allow the workpiece to be in a defined position align and feed to the radiation zone.
  • it can be provided that has the workpiece clamped to the carrier.
  • the system comprises at least two carriers, which alternate between the loading and Removal point and the radiation zone can be moved back and forth are.
  • This enables a first workpiece to be arranged on a first carrier and then the irradiation zone supply.
  • this first workpiece can be a second workpiece on the second Positioned carrier and then also the Irradiation zone are supplied. Then you can then the first workpiece is removed from the radiation zone and be replaced by another workpiece.
  • the carrier with the Transport device are releasably connectable. So can for example, be provided that the carrier with the Transport device can be screwed or clamped can.
  • the transport device is displaceable at least one held dolly includes.
  • the dolly can be designed in the manner of a drawer, for example be that kept sliding in a guide is. It is advantageous if the trolley between the loading and unloading point on the one hand and the irradiation zone on the other hand is.
  • the Transport device a rotatably held bogie, for example, a turntable.
  • a rotatably held bogie for example, a turntable.
  • To be irradiated Workpieces can be positioned on the bogie and then by turning the bogie first in the irradiation zone and after that Irradiation returns to its original position be transported.
  • the system includes a cover. It can advantageously be provided that the cover has an opening through which the Workpiece can be fed to the radiation zone and the system is removable.
  • the opening can for example be on the side be provided on the system so that the system is fully operable from this one side.
  • Particularly easy operability of the coating system can be achieved in that the workpieces fixable outside the cover on the carrier and can be removed from the support after irradiation and movable with the carrier through the opening are. This enables the operator to To optimally attach workpieces to the carrier without they are hindered by the cover of the system become.
  • Attachment is provided that the cover covers the bogie and the beams can be moved held on the bogie and through the opening are slidable.
  • the system then only has to position the bogie in this way be that a carrier with the opening of the Cover is aligned and thus moved through it can be.
  • such an irradiation system can in particular for the production of an interior fitting are used for motor vehicles. It is advantageous if the at least one Support for coating the workpiece and for curing of the coating material by means of UV radiation Molded part with a wall on which the workpiece, for example, the interior part in the area a surface to be coated under formation a gap space can be positioned, the Gap space then with liquid, by means of UV radiation curable surface coating material can be filled.
  • This enables a particularly inexpensive Production of an interior fitting, for example, by the carrier not only fixing the Serves workpiece on the transport device, but in addition to machining the workpiece, for example its coating.
