    The invention relates to a device for the surface treatment of a workpiece in a production line with a positioning frame for the workpiece to be treated, which frame has a coupling for a positioning drive.
    From US20170246652A1 a device for surface treatment, in particular for coloring workpieces, is known. The device consists of a container that can be hermetically sealed with a lid. The container is pierced by several connection lines, via which a fluid or powdery surface treatment agent can be introduced or discharged and an overpressure or underpressure can be applied. Furthermore, the container can be heated or cooled via a temperature control element attached to the outside of the jacket. Due to the complex design and equipment of the device, a high quality of surface treatment can indeed be achieved, but a coating process carried out in this device reaches its limits, especially at higher production rates. The production rate can only be increased by parallelization of several devices, which, however, leads to enormous investment costs due to the technical complexity of the device
    would.
    In order to increase production rates in the surface treatment of workpieces, US6471837 discloses a production line. The production line includes a central distribution chamber that guides the workpieces through various hermetically sealed sub-chambers. The sub-chambers
    can be evacuated and are with depending on the surface treatment process
    on the capital goods.
    For particularly large workpieces, such as car bodies, electrochemical dipping processes are known from the prior art. For this purpose, the car bodies are arranged on a positioning frame that can be rotated via a positioning drive and are thus immersed in an electrically conductive dip paint. When a direct voltage is applied between the car body, which acts as a cathode, and an anode, the dip paint falls out on the car body and remains there. In the course of the day, however, the quality of the paintwork decreases due to soiling of the immersion paint and changing particle concentrations in the immersion paint basin, especially with large production cycles. In addition, in such immersion processes, for example, the introduction of air bubbles leads to two-phase mixtures, which also
    Reduce surface treatment quality.
    The invention is therefore based on the object of proposing a device and a method for surface treatment of the type described at the outset, which, regardless of the type of surface treatment, increases the
    Manufacturing rate is allowed without sacrificing surface quality
    to have to accept the coating.
    Has the production line arranged resource supply units.
    As a result of these measures, all process steps required for surface treatment, be it the transport of the workpiece through the production line, the pretreatment of the workpiece, the application of various operating materials, such as substances for surface treatment, on the workpiece, the cross-linking of the substances for surface treatment, etc. a capsule sealed off from the environment. Depending on the workpiece, the capsule is dimensioned in such a way that it offers enough space to accommodate the workpiece, but nevertheless allows the atmosphere enclosed by the capsule (pressure, temperature, humidity, etc.) to be manipulated in the most energy-saving way possible, and thus allows the process conditions to be controlled precisely. According to the invention, the closed atmosphere is manipulated by connecting lines which enable the exchange of operating resources between the capsule and operating resources supply units arranged along the production line. Any active process components in the capsule itself are kept to a minimum. The capsule is designed as a reaction space for surface treatment of the workpiece and for manipulating the atmosphere in the capsule. In principle, materials for pretreating the workpiece, such as cleaning agents, materials for surface treatment, such as liquid or powder coatings, nanoparticles, but also materials for influencing the atmosphere, such as hot air, steam and the like, can be regarded as operating materials. If the capsule is equipped with simple electrical components, such as a temperature control element, electrical power is used as the operating medium. With a corresponding configuration of the capsule, electromagnetic radiations can be used as operating means for manipulating the atmosphere or the workpiece, which in this case are not passed through the connecting lines. Since the
    Connection lines not only for filling the capsule with operating materials, but
    Embodiment, form a separate unit from the positioning frame.
    In order to enable the capsule to be positioned or conveyed through the production line without hindrance and nevertheless to enable rapid and reliable coupling to operating material supply units, it is proposed that the positioning frame form the connection lines for flow connection with the capsule. The connection lines are therefore not loosely arranged on the capsule, but are instead guided through the frame. In a structurally particularly advantageous embodiment of the invention, the frame itself can be the connection line, so that separate connection lines between the operating material supply units and the capsule can be avoided and the required manufacturing effort can be reduced. To protect against the operating resources, for example against oxidation, the frame can have a corresponding inner coating. Regardless of whether the connection lines are led through the frame or formed by the frame
    twisting or tangling of the connecting cables can be prevented
    Inspection activities are made possible.
    So that the capsules can be connected to the equipment supply units quickly and reliably without restricting any possible movement of the capsule for distributing the equipment, it is recommended that the connection lines pass through the coupling for the positioning drive. Both the mechanical connection and the supply of operating resources can thus take place via a connection point which, in terms of its position relative to the operating resources supply units, is independent of the relative position of the capsule or the positioning frame. With a corresponding design of the coupling, the connecting line experiences only low bending moments, which results in a particularly long service life
    Connection lines is reached.
    In order to be able to move the positioning frame according to the invention with the capsules supported against them when the positioning drives are coupled between the individual operating equipment supply units and to be able to simply couple them to each operating equipment supply unit, it is proposed that the connecting lines be passed through the positioning drive. For example, the drive axis of the positioning drive connected to the positioning frame can be made hollow, so that the connection lines within this drive axis from the positioning frame through the positioning drive
    can be passed through.
    If the atmosphere in the capsule is to be manipulated during the application of an operating medium for surface treatment, the positioning frame can have a coupling axis connecting two opposing couplings, which forms two separate connecting line sections for different operating mediums for the two couplings. A connecting line section can accordingly have a first
    Be connected to the resource supply unit, which the interior of the capsule with
    Resource supply units.
    In order to achieve a complete application of the equipment to the workpiece and to prevent sedimentation of various particles in the equipment, it is proposed that the coupling axis connecting two opposing couplings forms a rotation axis for the positioning frame for evenly distributing the equipment in the capsule. A positioning drive of the positioning frame can therefore not only be provided for the translational movement of the capsule through a production line, but also for the rotation of the capsule about the coupling axis. For this purpose, two separate positioning drives, or a single positioning drive, can be provided, which allows both a translational movement of the capsule and a rotation about the
    Allows coupling axis as a horizontal axis of rotation.
    Energy-saving transport of the capsule through the production line can be achieved if the positioning frame has a chassis that is independent of the positioning drive. While the positioning drive can be guided on rails, for example, the chassis of the positioning frame can have a set of rollers to transfer the loads, whereby the
    Clutches can be relieved and their service life is increased.
    Particularly favorable conditions for loading the capsules with the workpieces to be treated arise when the height of the upper part of the capsule projects beyond the height of the lower part of the capsule supported on the positioning frame. The positioning frame preferably forms one with the lower capsule part
    Unit on which the workpiece is placed and with the positioning frame inside
    The lower part of the capsule is placed and the capsule is thus hermetically sealed.
    So that an electrical supply of any components arranged in the capsule interior can be made possible without impairing the detachability of the capsule, it is recommended that the capsule upper part can be connected to the capsule lower part via a flange encircling the capsule and having electrical contacts. Due to the arrangement according to the invention, the contact is still protected from corrosion, accelerated by any operating means in the
    Capsule interior or other environmental influences, protected.
    For a process-reliable exchange of operating resources between the capsule and the operating resources supply units, the upper part of the capsule can have inlet valves connected to the connection lines and the lower part of the capsule can have drainage valves for operating material connected to the connection lines. This enables the equipment to be applied evenly to the workpiece and, at the same time, to be vacuumed away without leaving any residue. The inlet valves can vary depending on the surface treatment process. If the device is used for powder coating, the inlet valves can, for example, use rotary bells, finger nozzles, baffle plate nozzles and / or flat jet nozzles
    feature.
    If the lower part of the capsule is penetrated by the positioning frame, not only do particularly compact structural conditions arise, but with a corresponding design of the connecting lines, liquid operating media can also be in
    can be conveniently removed from the capsule.
    The invention also relates to a method for the surface treatment of a workpiece moved on a positioning frame by positioning drives in a production line. In order to minimize the consumption of resources for the method without reducing the production rate or production quality, it is proposed that the workpiece be hermetically sealed
    lockable capsule is placed, after which the closed, on the
    pressure and humidity can be influenced.
    This means that the equipment is applied as evenly as possible, even on difficult applications
    accessible places of the workpiece is made possible, the with operating resources
    Rotation can take place before, during and / or after the application.
    In order to create a homogeneous and energy-saving crosslinking of equipment applied to the workpieces for surface treatment, it is recommended that at least one equipment has dielectrically or inductively excitable particles and that the electromagnetically permeable capsule is passed through an electromagnetic field to heat the particles. In principle, the particles can already be part of the equipment for surface treatment, as is the case, for example, with metallic pigments in powder or liquid paints. Alternatively, dielectrically or inductively excitable particles can be conveyed into the capsule as part of a hardening agent in a further process step. If the particles are now excited by the electromagnetic radiation of an electromagnetic field, they heat up. The heat generated in this way can be used to fix the paints, therefore to evaporate the solvents contained in the liquid paints or to cross-link the powder paints. It has been found that electromagnetic fields with a frequency of 30 kHz to 300 MHz are particularly well suited to stimulate the particles in the capsule and to generate the desired curing temperatures of preferably 150 to 200 ° C due to their sufficient penetration depth. The method according to the invention does not heat the workpiece, but rather only the layer containing the dielectrically or inductively excitable particles, so that the desired temperature conditions can be quickly reached and precisely regulated. A complete fixation of different lacquers can be achieved if the particles are exposed to the electromagnetic field for about 5 to 50 minutes. First calculations have shown that this, compared with known from the prior art
    Drying process, 90% of the drying energy can be saved.
    The subject matter of the invention is shown in the drawing, for example. It
    demonstrate
    1 shows a plan view of a production line with several devices according to the invention for surface treatment and operating material supply units,
    2 shows a schematic section along the line II-II on an enlarged scale,
    3 shows a plan view of a production line with two devices according to the invention for surface treatment and an emitter for generating an electromagnetic alternating field and
    4 shows a side view of a production line with several devices according to the invention for surface treatment and
    Resource supply units.
    A device according to the invention for the surface treatment of a workpiece has, as can be seen in particular in FIG. 2, a capsule 2 supported on a positioning frame 1. So that the capsule 2 can be conveyed along a production line shown in FIG. 1, the positioning frame 1 is connected to a positioning drive 4 via a coupling 3. As can also be seen from FIG. 2, two positioning drives 4 can also be provided, each of which is connected to the positioning frame 1 via a coupling 3. The capsule 2 can be hermetically sealed, creating a reaction space that is closed off from the environment. By keeping the reaction space as small as possible, a particularly resource-saving surface treatment can be made possible, since the process conditions can be influenced and optimized even by small flows of operating media. The manipulation of the atmosphere or the control of the process conditions in the reaction chamber and the application of operating materials for surface treatment to the same is carried out via connecting lines 5 which connect the capsule 2 fluidically with the operating material supply units 6 arranged along the production line. The operating material supply units can supply the capsule 2 with different operating materials depending on the type of surface treatment, whereby
    the production line for different surface treatment processes
    can be used without prompting complex measures to be constructed
    have to.
    As is disclosed in particular in FIG. 2, the positioning frame 1 itself can be part of the connection lines 5, as a result of which a simple flow connection between the capsule 2 and the resource supply units 6 is achieved. As a result of these measures, no connection lines 5 are exposed that would allow independent positioning,
    Promotion or an accessibility of or to the capsule 2 could impair.
    In order to enable the capsule 2 to be quickly coupled to the equipment supply units 6 and nevertheless to enable the capsule 2 to move freely, the connection lines 5 are routed through the coupling 3 and the positioning drive 4. The positioning drives 4, which, among other things, the step-by-step transport of the device through the production line to the task
    can be stored on rails 7.
    If the capsule 2 is to be supplied with several operating resources at the same time or if the process conditions, for example pressure, temperature and / or humidity, are to be influenced at the same time during the supply of one operating medium without impairing the free mobility of the capsule 2, the positioning frame 1 can have a the two clutches 3 have a mechanical coupling axis 8. The coupling axis 8 forms two
    connecting line sections separated from one another by a shut-off valve 9.
    The coupling axis 8 acts as a horizontal axis of rotation, whereby the capsule 2 can be rotated by a rotary drive 10 of the positioning drive 4. As a result, any operating resources in the capsule interior, that is to say in the reaction chamber, can be evenly distributed and homogeneously at the not shown
    Workpiece are applied.
    To support the displacement of the device according to the invention along the production line, the positioning frame 1 can include rolling
    Have chassis 11.
    The capsule 2 can be loaded with a workpiece in a particularly simple manner if the height H of the upper capsule part 12 corresponds to the height h of the lower capsule part
    13 towers above.
    So that, despite the releasable connection between the upper part 12 and the lower part 13 of the capsule, reliable electrical contact can be achieved without any cabling hindering the free positioning of the capsule 2, the upper part 12 and the lower part 13 of the capsule are connected to one another via a flange 14. For this purpose, the flange 14 has electrical contacts (not shown)
    on.
    For an operationally reliable entry and discharge of operating media into or out of the capsule 2, the capsule upper part 12 has inlet valves 15 connected to the connecting lines 5 and the capsule lower part 13 has outlet valves 16. In this embodiment, the shut-off valve 9 also takes on the function of a drain valve 16. The positioning frame 1 together with the drain valves 16 can
    Push through the lower part of the capsule 13.
    3 shows an emitter 17 for generating an alternating electromagnetic field through which dielectrically or inductively excitable particles contained in an operating medium, for example metallic pigments of a powder or powder, are shown. Liquid varnish or any nanoparticles are excited and then heat up. The heat generated can be used to crosslink on the
    Workpieces applied equipment are used.
    In Fig. 4, the possibility of rotating the capsule 2 about a horizontal axis of rotation is shown, for example. The dashed lines 18 show different fill level levels of the operating medium when filling or pumping out
    through the resource supply units 6.
