Definitions

  • the invention relates to a treatment device for cleaning and / or drying workpieces, having a workpiece carrier for receiving at least one workpiece having a workpiece axis, a nozzle device having at least one nozzle for spraying a treatment medium and which is mounted movably relative to the workpiece carrier, to direct the treatment medium in a direction of spray on the workpiece, wherein the nozzle device has a Leksache, which is arranged offset parallel to the workpiece axis.
  • the invention relates to a method for cleaning and / or drying of workpieces according to the preamble of claim 9.
  • Such treatment devices serve to liberate workpieces with a treatment medium, preferably a liquid cleaning agent or a gas or gas mixture of adhering substances of any kind.
  • the workpieces to be cleaned are mounted on a workpiece carrier and sprayed with a separated by one or more nozzles treatment medium.
  • the workpiece carriers and the nozzles are usually mounted relative to each other movable.
  • the relative movement may be a rotating relative movement or a rectilinear relative movement or a combination of these movements.
  • the relative movement serves to directly spray many areas of the workpiece with the treatment medium in order to achieve a particularly good cleaning result.
  • a workpiece on a rotatable and tiltable workpiece carrier is arranged, which is sprayed from a nozzle which is slidably mounted in three spatial directions and tilted about an axis. Due to this large number of degrees of freedom of the workpiece carrier and the nozzle, almost all sections of the workpiece to be cleaned can be directly sprayed by the treatment medium in this device. This also makes it possible to realize all possible distances and angles of the nozzle relative to the workpiece to be cleaned.
  • a disadvantage of this device is that the large number of degrees of freedom requires a complex control electronics and individual control programs to optimally treat different workpieces. Furthermore, it is disadvantageous that the single nozzle can spray only small sections per unit time and thus can only achieve a low throughput. For mass production of large workpieces or bulk material, this device is rather disadvantageous.
  • a cleaning system which has an arrangement for supporting at least one component which is to be cleaned and has the means for fastening the bearing arrangement in order to rotate the component about a first axis.
  • the arrangement is provided for conveying cleaning fluid from a pressure supply toward a component in the component storage arrangement, the fluid supply arrangement including a supply having an alignment arrangement for providing detergent from the pressure supply in an outlet direction transverse to the first Axis runs.
  • the arrangement is provided for positioning the liquid alignment assembly relative to the component storage arrangement.
  • a cleaning system and method for cleaning components having a chamber with a rotatable storage table for receiving components in a circular path and with a rotating spray dispenser having spray nozzles on the top, the bottom and the Side surfaces of the components are directed and wherein the spray dispenser is caused to oscillate, in a forward movement against the direction of movement of the parts on the turntable and in a backward movement.
  • the degree of movement of the spray nozzles varies in the two directions of movement at a lower speed in the forward motion and faster in the reverse motion to ensure that spray is continuously supplied by the spray nozzles in the forward motion, with the motion on the parts overlapping Strip effects on the parts to avoid.
  • a treatment apparatus and method for cleaning or drying workpieces in which a series of nozzles rotate around the workpiece to be treated.
  • the nozzles and the workpiece are moved relative to each other about a common axis of rotation.

  • a disadvantage of this device is that the nozzles are always guided around the workpieces to be treated in a circular path. As a result, the distance between the nozzles and the workpiece in the treatment varies, since the workpieces usually have no round base. Since the distance of the workpiece to be treated from the nozzles has a significant influence on the efficiency of the treatment, some portions of the workpiece are treated less intensively than others, which results in inhomogeneous cleaning of the workpieces.
  • the nozzle device is movably supported by at least one lever arm which is rotatably mounted about an axis parallel to the workpiece axis axis of rotation, wherein the lever arm has a length which is less than a distance between the axis of rotation and the workpiece axis.

  • the nozzle device has a plurality of nozzles which are distributed over the length of the nozzle device.
  • the nozzles on the nozzle device form at least one rectilinear row running parallel to the longitudinal axis.
