Definitions

  • the invention relates to a method for feeding sheets formed into can bodies to a can welding station.
  • the invention further relates to a device for performing the method.
  • the sheets are known to be stacked from a stacking table and fed to a round apparatus which forms the can frame.
  • the shaped can frame is then conveyed to the welding station, where the longitudinal seam of the can is made.
  • Advances in welding technology allow the feed rate to be increased up to 150 m / min. to increase. In such a feed speed range, however, the stacking of the sheets and the shaping of the frames pose problems.
  • the invention is therefore based on the object of providing a feed method for the can welding station which can also be used at high feed speeds and which works reliably.
  • This object is achieved in a method of the type mentioned at the outset in that sheets are delivered from at least two stacking stations to at least two frame forming stations and that the shaped frames are brought into a common linear sequence for feeding into the common welding station.
  • this is achieved in a method of the type mentioned at the beginning by delivering sheets of double frame width via a cutting device, which cuts sheets of single frame width therefrom, to two frame forming stations, and that the shaped frames are supplied for feeding be brought into the common welding station in a common linear sequence.
  • Figure 1 shows schematically the feed elements to a (not shown) welding station for the welding of can bodies.
  • the feed elements have a first stacking table 1 and a second stacking table 2.
  • a stack of flat sheets is arranged on each stacking table 1, 2. These sheets are each stacked individually from the table and delivered to a frame forming station 5 or 6 via a conveyor path 3 or 4.
  • a cylindrical can frame is formed from the flat sheet.
  • two frames 7, 8 or 9, 10 or 11, 12 are formed simultaneously. After shaping, both frames are ejected from the frame molding stations 5, 6 located one behind the other in the feed axis. The frames are therefore already in a linear sequence in the feed axis of the welding station.
  • the stacking tables 1, 2 introduce new sheets into the two frame forming stations. It is readily apparent that with this arrangement, the stacking tables and the frame-forming stations can work with a cycle number that is half that of the welding station, in order to provide the required number of frames. With this arrangement, however, a larger conveying stroke is required to eject the two shaped frames from the two frame molding stations.
  • FIG. 2 shows an alternative embodiment of the invention.
  • a stacking table 21 is provided, on which a stack of sheets is arranged, the width of which is twice as large as the width of the sheets of the variant shown in FIG. 1.
  • a sheet is now stacked from the stacking table 21 and guided along the conveying path 23 to a cutting device 20.
  • This cutting device 20 cuts two sheets of half width from the one sheet, which are each delivered along the conveying path 25 or 24 to a frame forming station 5 or 6.
  • the frames 7, 8 are again formed simultaneously and then ejected. This process is the same as for the variant according to FIG. 1.
  • the same advantages also result.
  • FIG. 3 shows an embodiment of the first solution variant with two stacking tables.
  • the same reference numerals as in Figure 1 basically denote the same elements.
  • two metal sheets are introduced simultaneously into two Zwargenformungen 5, 6 and formed there into a frame.
  • the frame forming stations 5, 6 are not located in the feed axis 50 to the welding station, but in parallel to it.
  • the frame molding stations also eject the molded frames 7, 8 into an area between the two frame molding stations.
  • the frames are then initially moved in parallel from this area until they lie in the feed axis 50.
  • the advantage of this arrangement in addition to the already mentioned advantage of half the number of cycles, is that the large conveying stroke for the frames, which according to FIG.
  • the transverse displacement of the frames to the conveyor axis 50 can e.g. take place with a circumferential band, which has individual chambers, into each of which the molded frames are inserted from the frame molding station.
  • FIG. 4 shows a further embodiment, the same reference numbers denoting the same elements as before.
  • the two frame forming stations 5 and 6 are arranged on both sides of the feed axis 50.
  • the finished frames 7 and 8 are each brought from opposite sides by a transverse movement into the feed axis 50. This transverse movement can again be brought about with a circulating belt which has chambers for the frames.
  • FIG. 5 shows a further embodiment, similar to that of FIG. 4.
  • the two frame forming stations arranged on both sides of the feed axis 50 5 and 6 the frames 7 and 8 from the same conveying element for cross-conveying.
  • This conveyor element can in turn consist of a conveyor belt with chambers, which, however, changes its direction. Depending on which frame 7 or 8 has to be brought into the feed axis 50.
  • FIG. 6 shows a further embodiment, the same reference numbers as previously used again designating the same elements.
  • the shaped frames are ejected parallel to the feed axis from the frame forming stations 5, 6, which are here on both sides but parallel to the feed axis 50, the ejection taking place in each case by one or two positions in the direction of the feed axis.
  • the frames are then moved transversely to the feed axis from these parallel positions. This can be done alternately, so that the double conveying stroke does not have to be carried out in one cycle with the movement parallel to the feed axis.
  • FIG. 7 shows a further embodiment.
  • the same reference numerals designate the same elements as before.
  • This turntable subsequently turns the frames 7, 8 into the feed axis 50.
  • its empty chambers 31, 32 are again in front of the frame forming stations and can be filled with new frames.
  • the frames 7, 8, which now lie in the feed axis are conveyed further in the direction of the feed axis, the corresponding chambers of the turntable being emptied again.
  • the rotary table then rotates another 90 ° and the process is repeated.
  • FIG. 8 shows a further embodiment, the same reference numbers as previously denoting the same elements.
  • the frame forming stations are at an oblique angle to the feed axis 50 oscillating table 35 with three receiving chambers rotates the frames 7 and 8 alternately into the feed axis 50.
  • FIG. 9 shows a further embodiment, the same reference numerals denoting the same elements as previously.
  • the two frame forming stations 5, 6 are here on both sides of the feed axis 50.
  • a swinging table is provided, which receives two frames 7, 8 and rotates in the feed axis 50.
  • FIG. 10 shows an embodiment in which the frames are brought into the feed axis 50 along a curved conveying path.
  • a conveyor path is assigned to each frame forming station 5 or 6.
  • FIG. 11 shows a similar embodiment to FIG. 10, the frame forming stations here being at an oblique angle to the feed axis 50, which shortens the curved conveying path.
  • FIG. 12 also shows an embodiment with curved conveying paths for the shaped frames, wherein here the frame forming stations 5 and 6 are located on both sides of the conveying axis 50, so that the curved conveying paths do not run parallel.
  • FIG. 13 also shows an embodiment in which a reciprocating table with two chambers is provided after the frame forming stations, which, by means of a back and forth movement, couples the one chamber to the corresponding frame forming station and moves the other chamber into the feed axis 50 .
  • the molding of the frames and the transportation of the same can partially or completely coincide; during the molding process, a transport process takes place at the same time.
  • one pendulum gear can be provided, or two independent pendulum gears can be provided, so that the pendulum transport movements can take place mechanically independently of one another.
  • Both stackers can work synchronously or out of phase, depending on the design and type of further transport of the can bodies.
  • the separate forming stations can be shaped synchronously or asynchronously in order to make optimum use of the time available, to prepare rounded frames or to coordinate them with further transport.
