Definitions

  • the invention relates to a method for cleaning the surface of a plastic article for pretreatment for a subsequent coating, in particular painting process.
  • An alternative method uses a degreasing system for plastics, which is divided into several stages.
  • cleaning is carried out using an acidic, alkaline or neutral chemical and deionized water, this step being the pre-cleaning.
  • the acidic, alkaline or neutral solution comes with sprayed high pressure on the plastic object.
  • This pre-cleaning is repeated again in a second stage.
  • the third stage is then rinsed with demineralized water and the fourth stage is rinsed with pure demineralized water.
  • This degreasing process can include even more stages, but the structure of the processes is essentially retained. The cleaning effect is only suitable for lightly soiled plastic parts.
  • the cleaned plastic objects After each of the ultrasonic or degreasing cleaning processes described, the cleaned plastic objects must be blown off with air and then dried at approx. 80 - 90 ° C. In order to continue with the coating process afterwards (for example a flame treatment step, the application of a primer or painting) then the objects have to reach room temperature again, which is achieved by an upstream cooling zone at approx. 20 ° C.
  • a third cleaning method is that a large amount of ionized air is blown onto the plastic parts with a certain dwell time. This method is indeed suitable for plastics that are only very slightly soiled, for example with flying dust, and from which this dust can be removed very easily. This method is unsuitable for stubborn dirt. Finally, the manual cleaning of each plastic object with or without detergent and deionized water remains to be mentioned, which is, however, at best suitable for the separate processing of individual plastic objects, but not for large series.
  • the invention is therefore based on the problem of specifying a method which allows the surface of small and large plastic objects to be cleaned in a simple manner while achieving a very good cleaning result and the possibility of large-series cleaning.
  • At least one working robot is used, on which at least one blasting nozzle is provided, by means of which pellet-like dry ice particles are blown onto the plastic object, the blasting nozzle using the arm robot to clean a certain surface section is automatically moved along the plastic object during blowing.
  • pellet-like dry ice particles are blown onto the plastic object at a relatively high pressure in the range of several bars using a jet nozzle.
  • These dry ice particles consisting of solidified carbon dioxide have a temperature lower than - 79 ° C, at temperatures higher than - 79 ° C the solidified dry ice goes directly into gaseous CO 2 without melting or leaving liquid residues. Due to the fact that these particles are blasted onto the plastic surface at high pressure, this is locally cooled to a great extent, whereby a detachment effect of any impurities is achieved, which can be blasted in this way. Surface temperatures down to a minimum of 0 ° C are reached.
  • the cooled surface is heated with the sufficiently large heat capacity of the material of the plastic object, which usually has a wall thickness of several mm, so that the next processing step can take place immediately after the cleaning has ended, since the plastic object has warmed up again to room temperature ,
  • the jet nozzle itself is arranged according to the invention on a movable work robot, by means of which it is moved fully automatically along the plastic object, ie the robot moves the plastic object and moves the jet nozzle so that this can irradiate the surface piece by piece. This process takes place fully automatically, so that it is ensured that the desired surface section is also completely processed.
  • the method according to the invention thus on the one hand allows excellent cleaning of the surface using the dry ice particles blasted at high pressure, which also allow stubborn dirt and greases to be removed, and on the other hand the automated nozzle movement using the working robot ensures 100% surface treatment At the same time automation of the work process, so that even large series can be cleaned easily and safely without manual work.
  • Plastic object is moved into the work area of the robot by means of a conveyor.
  • the plastic object is simply placed on the conveyor by a worker, for example a conveyor belt on which several goods carriers, so-called skids, are arranged, after which the automatic transport to the working robot takes place.
  • the movement can be continuous, ie the plastic object is also moved past the robot while the dry ice particles are being inflated.
  • the working speed of the robot or movement speed of the jet nozzle and, if appropriate, also the blow-out pressure must then be selected.
  • the movement can also be clocked, ie the plastic object to be cleaned rests while it is being processed.
  • the irradiation itself is expediently carried out in a closed cabin, which may have openings for the supply of the plastic objects, from which air is drawn off on the bottom side and preferably filtered air is supplied on the top side in order to achieve air circulation which on the one hand collects the emitted impurities in the area of the Soil allows, on the other hand, the C0 2 formed due to the sublimation of the dry ice particles can be deducted, so that a concentration is avoided.
  • the method according to the invention serves to automate and simplify cleaning as much as possible and to create the possibility of processing a large number of objects in series.
  • plastic objects that change in type, size or shape.
  • the type and / or the size and / or the shape of the plastic object is determined by means of a suitable automatic detection means before the processing is started and the path of movement depending on the result the jet nozzle is determined or selected, this preferably being done by selecting an object-specific control program that controls the operation of the working robot, this selection being able to be made automatically or can also be selected manually after detection of the respective plastic object.
  • the detection means thus recognizes the respective object and reports this to the control device controlling the robot operation, which then controls the movement of the robot while processing the object-specific control program. If necessary, in addition to the object parameters mentioned, the plastic material from which the object is made can also be detected, so that the jet pressure can also be varied depending on the material.
  • an omnidirectional, a flat jet or a cyclone nozzle can be used as the jet nozzle, a cyclone nozzle having a somewhat larger effective range. Since the objects to be processed can sometimes have complicated shapes, such as a bumper that is bent at the ends and also folded in the area of its longitudinal edges, the greatest possible mobility of the jet nozzle is required so that it conforms to the contours of the surface area to be processed can follow.
  • a working robot should preferably be used in which the jet nozzle can be moved about three axes with respect to a robot arm carrying it.
  • a working robot should preferably be used, in which this robot arm itself is pivotally arranged on a further robot arm, which in turn is arranged on a rigid robot base so as to be movable about two axes. In this way, the jet nozzle can be fully moved or swiveled around a total of six axes.
