Definitions

  • the present invention relates to a powder application method and a powder application device according to the preambles of claims 1 and 8 and a can body according to the preamble of claim 19.
  • the coating of the welded longitudinal seams of can bodies with electrostatically charged powder is known and is predominantly used on can bodies in which sensitive filling goods are filled.
  • Polymer resins e.g. Epoxy, polyethylene and others are used, which are conveyed to the weld seam in the finest resolution in an air stream and electrostatically charged shortly before hitting the seam.
  • the powder When leaving the transport line carrying the powder, the powder is distributed in relation to the expansion the weld seam wide area. Parts of the fuselage are thus also coated, which would not have to be covered, but on the other hand, the weld seam, which often has a sharp edge, has less powder to lie on to ensure reliable coverage.
  • a method is known from US Pat. No. 3,713,862, with which a defined narrow and uniform powder application strip is applied to the outside of the seam with the aid of the lateral areas of the seam-covering tape.
  • Coating the inside of the seam is not possible in this way because the slotted masking tape is not covered by the welded, i.e. closed hulls can be performed. Furthermore, uniform powder application over the entire coverage area is not advisable. If enough powder is applied to reliably cover the welding edges of the seam, there is too much material in the side areas, which is uneconomical given the high prices for powder. If the application thickness is kept low, the seam is poorly covered.
  • German Offenlegungsschrift No. 29 33 641 describes a powder application device in which the lateral powder scattering by partial separation of the air from the powder shortly before (the exit) prevent the powder from escaping from the spray head. Shortly before reaching the seam, the powder is separated from the air by centrifugal separation, for example with a reversing loop in the transport line, and sprayed approximately parallel to the seam into a spray room, where it is charged by a row of electrodes also arranged parallel to the seam.
  • the introduced parallel to the flow of powder also in the spraying air flow mixes there forced läufi g again with the powder and generating a powder / air cloud.
  • This device hardly enables a concentrated application with a few powder particles scattering into the environment; a defined distribution of the powder across the seam area is not possible.
  • the spray chamber consists of a porous material. Gas or air is blown into the spray space through this porous material in order to blow the powder particles introduced essentially parallel to the weld seam against the seam area. A defined order that only covers the very narrow seam area is excluded with this arrangement. This inevitably leads to large powder consumption.
  • baffles for braking and deflecting the air / powder mixture results in a very complicated structure of the spray head, which tends to clog (powder nests).
  • suction and reprocessed In addition to the high costs for compressed air and suction air, there are additional costs for the reprocessing and the loss of part of the recycled powder.
  • All known powder application devices directly or indirectly produce a powder / air cloud in a spray room, which is electrostatically charged in the spray room and is directed against the seams to be covered, which are guided past the spray room, both as a result of this charging and as a result of the excess pressure and the air currents in the spray room.
  • the object of the present invention is to provide a device which overcomes the disadvantages of the known devices.
  • Another object of the invention is to apply the powder conveyed into an air stream to the seam area with a small proportion of conveying air.
  • Another object of the invention is to design the device in such a way that it can be arranged as close as possible to the welding machine.
  • a further advantage of the invention is that the application thickness can be varied in the individual areas by dividing the powder / air flow over several lines.
  • Another advantage of the invention is that by moving the powder feed lines close to the weld seam, it is possible to work with a small amount of air and less pressure, so that less powder excess has to be reprocessed and, in addition, few powder particles are flung next to the seam area. Furthermore, a concentrated application of the powder without static charge on the seam is also possible.
  • Another advantage of the invention is that the powder layer thickness can be metered well across the seam due to the arrangement of two feed lines lying next to one another.
  • Another advantage of the invention is that the helical routing of the lines largely prevents the occurrence of blockages.
  • suction can be used to easily remove the excess powder from the application zone in addition to the outlet openings. Since this powder is not contaminated, it does not need to be cleaned.
  • Another advantage of the invention is that the powder / air flow can be divided without interference in the cone-shaped space.
  • Another advantage of the invention is that, thanks to modest dimensions, the device can be provided directly on the welding machine, which, thanks to the short transport path from the welding point to the device, makes it possible to position the seam to the spray head exactly, and thereby the powder on the the weld still adheres to the hot seam and can be applied exactly to it.
  • a further advantage of the invention is that the additional heating of the seam area or the keeping of the same at the same time makes it possible to apply powder with little or no charging. In many cases, the powder's frictional charge in the supply lines is sufficient to ensure sufficient adhesion to the hot seam.
  • FIG. 1 shows schematically a known seam welding machine 1 with the electrode rollers 2, 3, some freshly welded can bodies 4, the powder application device 5 with the spray head 6, the external suction 7 and the combined processing and reprocessing system 8 and one Known heating device 9 shown for melting the powder on the seam.
  • An electrical system for generating the high voltage for charging the powder is shown symbolically and is designated by reference number 10.
  • the spray head 6 is shown in Fig. 2 on an enlarged scale as a longitudinal section.
  • a can body 4 located above the spray head 6 is shown, which passes the spray head 6 from left to right (arrow A).
  • the upper cut surface 11 through the can 4 runs exactly through the weld seam 12 of the fuselage 4 and lies above the spray opening 13.
  • Four feed lines 15 for a powder / air mixture open, inclined to the horizontal, into the room 14.
  • Another, larger in cross section Line 16 opens into the head space 17 at the end of the spray head 6.
  • the line 16 is connected to a suction system that leads to the processing system 8.
  • the lines 15 begin in a cone-shaped space 18, in which the powder / air mixture from the main line 19 is divided between the lines 15 if more than two lines 15 are provided.
  • Needle-shaped electrodes 20 can protrude into the conical ring-shaped space 18. They are coaxial to the lines 15 leading out of the space 18. They are connected to the high voltage source 10 via an annular copper electrode 21 and a line 22.
  • the space conditions do not allow all the lines 15 to be routed in parallel in the lower half of the spray head 6.
  • the lines 15, as shown in FIG. 2 are preferably led away from the conical ring-shaped space 18 in a helical manner.
  • the spray opening 13 can have sealing elements 23 in the form of rubber or bristle strips on the side. These serve to seal or laterally limit the emerging powder to the can body 4.
  • the head space 17 is closed towards the can 4 with a lid 24.
  • the top view in FIG. 3 shows that the opening 13 in the spray head 6 has two zones 25 and 26 of different widths.
  • the slot zone 25 is narrower than the slot zone 26 on the output side.
  • a can 4 running in via the spray head 6 is visible in FIG.
  • the central part, drawn in a light grid, represents the weld seam 12.
  • the unpainted cutouts 27 close immediately adjacent to it on, further out the protective lacquer 28 already applied to the can plates in a flat state.
  • the approximate width ratios of the weld seam 12 and the regions 27 adjacent to it, also to be covered, and the slot zones 25 and 26 of the opening 13 can be seen from this illustration.
  • the narrow zone 25 is slightly wider than the seam 12, the wider zone 26 exceeds the overall width of the seam 12 and the recesses 27.
  • the cross section of the opening 13 widens continuously from the inlet-side to the outlet-side end of the spray head 6.
  • the supply of the powder / air mixture remains the same, as shown in FIG. 2, distributed over a plurality of lines 15.
  • the distance between that The line end and the weld seam 12 are in the range from 2 to 5 mm, preferably approximately 2.5 m.
  • the opening cross section of the mouths of the lines 115 can be round or angular; however, the lines 115 can also be guided twice and in particular lie next to one another at the wide point 26 of the opening 13. Easily replaceable end pieces 315 are preferably attached to the lines 115.
  • further lines 116 can be provided before and after each line 115. These lines 116 preferably open to the base of funnel-shaped depressions 117, which are located between the powder lines 115.
  • the suction lines 116 are connected to the processing system 8 via the suction line 16. ( Figures 5/6)
  • sealing elements 23 or moving plastic belts can protect the areas next to the seam 12 from the deposit of powder particles.
  • these covers can also be dispensed with, in particular if the lines 115 open very close to the weld seam 12 and consequently the powder / air flow can also escape at a very low speed, by the remaining free path to to overcome seam 12. Powder particles which do not reach the seam or which loosen again are immediately removed from the spray opening through line 116.
  • the distribution of the powder / air stream can be at the end of the feed line 19, of course, also via a Y-shaped splitting of the line 19.
  • the electrodes 20 can then preferably lie in the legs of the Y.
  • the cross sections according to FIGS. 7, 8, 9 and 10 show an embodiment of the lines 15, 115, which let the powder emerge vertically as a band-shaped stream, or at least at an obtuse angle to the seam.
  • the initially round cross-section of the powder lines 15, 115 has, starting at the arcuate part of the line 15, 115 below the outlet opening, a rectangular cross-section which continues to the outlet opening.
  • the powder particles floating in the air flow in the horizontally lying section of the line 15, 115 are distributed over the flat outer radius and slide upwards where they leave the line 15, 115 as a narrow band standing transversely to the weld seam.
  • the can bodies 4 which are longitudinally welded between the welding rollers 2 and 3 and carried by a transport system 29, reach the powder application device 5 Spray head opening 13 a narrow, only just covering the welding seam 12, applied powder strips.
  • the powder is applied in an area which not only includes the weld seam 12 but also the adjacent areas 27.
  • the already covered seam area 12 is again coated with powder.
  • the adhesion of the powder to the can 4 is achieved in a known manner either by electrostatically charging the powder particles on the electrodes 20 or by friction on the feed lines 15, the can 4 having an opposite charge, or the adhesion is achieved by gluing at the temperature of the weld seam 12, which is still hot or kept hot by a heat source (not heated) and exceeds the melting temperature of the powder.
  • the powder is supplied in the air stream through line 19. After the division in the conical space 18 or in the y-shaped end of line 19 into one or a plurality of lines 15 and the static charge is the (powder / air flow)
  • the order can be limited exactly to the width of the slot opening 19.
  • the powder parts not adhering to the can 4 and the transport air are fed through the suction line 16 out of the head space 17 and / or the funnel-shaped depressions 117, the powder particles emerging between the subsequent cans 4 are removed by the suction 7 and fed back to the processing plant.
  • the can bodies are guided along a heat source or heater 9 so that the powder melts and forms a well-adhering coating on the can seam 12.
  • the method and the device described above for covering the inner seam can of course be used analogously for the outer seam covering.
  • the method described can also be used to apply the powder to an underlying seam.
