Definitions
- the invention relates to a method and a device for applying liquid anticorrosive agents, in particular paint, to areas of packaging containers or container parts made of metal which are at risk of corrosion and which, after painting the container or container parts, are subjected to processing operations such as cutting, scoring, welding, shaping or the like. , have arisen as a result of local damage or removal of the paint.
- lacquers In order to largely avoid damage to the all-round painted container or container parts during subsequent deformation or processing, lacquers have been used so far that they have been adjusted so that they have both a high toughness and, as a result, a large degree of expansion and sufficient mechanical strength.
- paints are relatively expensive and often difficult to adjust in terms of the properties required.
- lacquers of different compositions are necessary. Nevertheless, when using these paints, corrosion-prone areas always occur when cutting or stamping operations on the containers or container parts have to be carried out after they have been painted. This creates cut edges that can never be covered by the coating previously applied to the container or container parts.
- the invention has for its object to develop the method of the type mentioned so that a precise and material-saving coating or painting the local damage to the container or container parts can be done with the same anti-corrosion agent as the previous all-round coating.
- the solution to the above problem is that the areas at risk of corrosion on the containers or container parts are applied by the ink-jet method by program-controlled, punctiform application of the anti-corrosion agent to form a film-like application.
- the ink-jet method can be used to apply targeted coatings that cover only the areas of the damage, regardless of the geometry of the container or container parts or their local damage. It is possible to limit the coatings only to narrow areas, such as scratched edges or cutting lines, without the need for an immersion treatment or a heat treatment, such as, for example, when melting electrostatically applied powder.
- the locally restricted areas can be coated both with locally fixed or held containers or container parts and also during the movement or during the transport of the containers or container parts. Due to the targeted and metered application of the corrosion protection agent according to the ink-jet method, an extremely short period of time is required for the application of the corrosion protection agent to the areas which are generally very localized, whereby the layer thickness to be applied can be varied.
- the surface application can be achieved by partially covering all adjacent points of the applied anticorrosive agent or without overlapping by the liquid flowing into adjacent points without excess material having to be applied to the areas to be covered and removed again.
- the aforementioned measures make it possible to align all the containers or container parts before the punctiform application of the corrosion protection agents in such a way that the similar damage to the containers or container parts resulting from the previous processing is in the same place when passing through the spray nozzle arrangement, which makes it particularly simple Control of the spray nozzle arrangement results.
- a particularly useful device for this is characterized in that in the course of a conveying path of the container or container parts, a stationary nozzle arrangement is provided in connection with an upstream device for aligning and / or fixing the container or container parts on the conveyor, around the container ter or container parts on the conveyor in a respective matching position with respect to the nozzle arrangement and / or to keep.
- the above-mentioned device can be designed in a simple manner as an additional station of a processing machine, in that the parts machined on the machine, while maintaining their relative position with respect to a holding device, are transferred to the coating station downstream of the processing stations, in which the damaged nozzle arrangement is used by means of the fixed nozzle arrangement or areas free of corrosion protection agents.
- the nozzle arrangement can be adapted in a particularly simple manner to the geometric shape of the respective corrosion-prone area of the container or the container part. In addition to a simple nozzle arrangement, this also achieves very simple control of this nozzle arrangement, in order to achieve the coating of the damaged areas, in particular when the container or container part is held stationary.
- the device in such a way that an optical path along the conveying path of the containers or container parts or electronic scanning device for ascertaining the position of the containers or container parts and the areas at risk of corrosion present thereon, and a device for converting the scanning signals or the captured image in pixels and control signals derived therefrom and a block-shaped arrangement of spray nozzles dimensioned larger than the respective area at risk of corrosion is provided in connection with a program control device for the spray nozzles which can be actuated as a function of the control signals.
- a camera can be used for this, for example in the manner of a video camera, by means of which the captured image is already broken down into pixels which are to be converted into control signals in a known manner in order to actuate the program control device for the spray nozzles.
