Definitions

  • the invention relates to a method for forming metal sheets into can bodies and feeding the can bodies to a welding station according to the preamble of claim 1. Furthermore, the invention relates to a device for carrying out the method according to the preamble of claim 3. (US-A-2864933)
  • US-A-2864933 shows forming individual sheets in a linear forming station. To transport the sheets, they are individually attached to a chain conveyor so that the high transport forces can be applied during the deformation in the tapered guides; this type of transport is not ideal for high cadences.
  • US-A-3204847 shows the linear shaping of a tube, from which frames are separated later.
  • the invention is therefore based on the object of shaping and conveying the individual sheets in such a way that the highest possible cycle speed can be achieved at the welding station.
  • the device for performing the method is characterized by the characterizing features of claim 3.
  • a can welding machine is shown schematically.
  • the machine has, in a known manner, an upper welding roller 15 and a lower welding roller 16 as well as a supplied welding wire 14 in order to weld the can seam of the can frame 11.
  • the welded can body 12 is removed for further processing.
  • the sheets are shaped into can bodies and fed to the welding station.
  • this feeding and shaping is now designed in such a way that the individual sheets 2-10 are shaped along the conveying path.
  • the sheets are initially on a stacking table 1.
  • the sheet stack is shown only by the top sheet 2 and the two bottom sheets 3, 4.
  • the bottom one Sheet is pulled off the stacking table and moved along the straight conveyor line to the welding station.
  • the sheet is gradually deformed into a can frame, as is shown with the sheets 5-10 in Figure 1.
  • Figure 2 shows schematically a side view of the conveyor line. Individual sheets are stacked by the destacker 1 and first fed to the pair of draw-off rollers 21. This is followed by profile roller pairs 22-31, which deform the respective sheet 5, 6, 7, 8 in regions along the conveyor line, so that a can frame results from the initially flat sheet along the conveyor line.
  • Figure 3 shows the same conveyor line in a plan view.
  • the conveyor belts 40, 41 and 42 can also be seen, which also serve to transport the frame.
  • the outer rollers under the sheet are shown; the inner rolls lying above the sheet are not shown in FIG. 3.
  • FIG. 4 shows a view of the pair of profile rollers 29 for a more detailed explanation of the shape of the can frame.
  • the outer roller arranged below the sheet and the inner roller arranged above the sheet each have a curved outer shoulder.
  • the associated outer shoulders of the two rolls each form the rounding zone in which the corresponding area of the sheet is deformed.
  • Figure 5 shows the individual stages of such a deformation of a flat sheet into a cylindrical can frame.
  • the stage 1 of the deformation shown in FIG. 5 corresponds to the deformation caused by the pair of rollers 22, the stage 2 of the deformation which is caused by the pair of rollers 23, etc.
  • the pair of rollers 29 shown in FIG. 4 effects the deformation corresponding to stage 8 of FIG. 5.
  • the rounding of the can frame takes place in sectors in ten stages, with each stage being rounded by 2 x 18 °.
  • a part of the conveyor section, which is used to calibrate the can frame, is connected to the sector circular section of the conveyor section formed by the profile roller pairs 22-31.
  • a forearm 50 is provided for calibration, which is attached to a holder 51 and onto which the frame is pushed.
  • pre-calibration rollers 52 and 53 initially act on the can body.
  • conveyor belts 43 are also provided in the calibration section.
  • the frame After the pre-calibration, the frame reaches a calibration ring which is provided with a plurality of calibration rollers 56.
  • FIGS. 2a and 2b each show the pre-calibration and the calibration in a vertical sectional view. After calibration, the can frame is inserted into the welding station known per se. Since this is known, it is not further explained here.
  • FIG. 7 shows the formation of a non-round can frame, with thirteen forming steps taking place.
  • Figure 6a shows the inner rollers 60, 61 and the outer roller 72 during the molding step from stage 1 to stage 2 of Figure 7.
  • Figure 6b shows the rollers for the molding step from stage 5 to stage 6.
  • Figure 6c accordingly shows the molding step with the Rolls 67, 68 from stage 9 to stage 10 and
  • FIG. 6d shows the last shaping step from stage 12 to stage 13.
  • 70 to 74 denote conveyor belts for the transport of the frame.
