Definitions

  • the invention relates to methods for producing transformer cores, which are formed from a plurality of stacked sheets, wherein the sheets are unrolled from a supply roll continuously, subsequently cut to length and shape, conveyed after cutting over a conveyor belt system and stacked on a stacking table ,
  • a method for manufacturing transformer cores according to the preamble of claim 1 is in DE 3836790 as in DE 2613150 disclosed.
  • the invention has for its object to provide methods of the specified type, in which complete transformer cores in E and C shape are made directly from the manufacturing plant for the individual sheets, the efficiency of the entire system or in the production of transformer cores essential is increased and the production costs are substantially reduced.
  • the inventive method is characterized primarily by the fact that both individual sheets and packages with a plurality of sheets are stacked directly to a transformer core. Only then is the respective stacking table moved to the next position for stacking the next individual sheets or sheet metal packages. This results in a tremendous time savings. A further time saving is achieved in that a plurality of stacking tables or stacking tables are provided with turntables mounted thereon, whereby multiple transformer cores can be produced simultaneously.
  • transformer cores 1 which are formed from a plurality of sheets 2 - 6, the sheets 2 - 6 are continuously unrolled from a supply roll in a plant, then cut to length and shape, after cutting over a Promoted conveyor belt system and stacked on one or more stacking tables 11.
  • a first method (see in particular Fig. 3 ) are alternately in each case alternately a plurality of sheets of a leg side 2 nd.4 of the transformer core 1 on the stacking tables 11 and a plurality of sheets of a yoke side 5 and 6 on tray tables in at least two in the conveying direction of the sheets 2-6 stacked stacking stations 12 15 stacked on top of each other.
  • Such stacked packages of sheets 2 - 6 consist for example of 3 - 14 sheets.
  • the handling systems 14 put the packets of sheets of a yoke side 6 and 5 with their ends to the an ends of the packets of the sheets of the leg sides 2, 4 and the packets of the sheets of the center leg 3 on the stacking tables 11 from.
  • the method steps described up to here are repeated until the total height of the respective transformer core 1, which has an open E-transformer core (see FIG Fig. 1 ), on whose leg sides 2, 4 and the middle leg 3 later the windings are applied. Only then are the sheets of the other yoke side 5 or 6, which were stacked on the tray tables 15, applied to the leg sides 2, 4 and the middle leg 3 of the E-transformer core 1 by hand.
  • a second method are also in at least two in the conveying direction (a) of the sheets stacked stacking stations 12 initially alternately each alternately a plurality of sheets of a leg side 2 or 4 of the transformer core 1 on the stacking tables 11 and a plurality of sheets of a yoke side 5 and 6 in Receiving devices 16 stacked one above the other.
  • alternately a plurality of sheets of the other leg side 4 and 2 of the transformer core 1 are stacked on the stacking tables 11 and a plurality of sheets of the other yoke side 6 and 5 in other receiving means 13 stacked on top of each other.
  • a plurality of sheets of the center leg 3 of the transformer core 1 are alternately stacked on top of each other, wherein at the same time Handling systems 14, 17 rotate the packets of sheets of the two yoke sides 5 and 6 in the orthogonal position to the conveying direction a. Thereafter, the handling systems 14, 17 place the packets of sheets of the yoke sides 5 and 6 with their ends at the ends of the packets of the sheets of the leg sides 2, 4 or the packets of the sheets of the center leg 3 on the stacking tables 11.
  • This third method in which an open C-transformer core is stacked (see Fig. 2 ), differs from the first method only in that the stacking of the center leg 3 is omitted. Otherwise, the process steps of the two methods are identical.
  • the fourth method in which a closed C-transformer core is stacked, also differs from the second method only in that the stacking of the center leg 3 is omitted. Otherwise, the process steps of the two methods are identical here as well.
  • At least two 21, 23 of at least four 21, 22, 23, 24 in the conveying direction a of the sheets 2 -6 arranged one behind the other, mounted on stacking tables turntables is in a fifth method, first alternately a plurality of sheets of a leg side 2 and 4 of the Transformer core 1 stacked on top of each other, the two other turntables 22, 24 are moved to the appropriate position and rotated ( Fig. 4a ). Again, there is such a stacked package, for example, 3 - 14 sheets.
  • the two other turntables 22, 24 is then alternately stacked one above the other the first packet of sheets of metal sheets of the other leg side 4 and 2 of the transformer core 1, wherein the turntables 21, 23 each in the position for stacking the sheets the respective one yoke side 5 and 6 of the transformer core 1 are moved and rotated ( Fig. 4f ).
  • the other turntables 22, 24 each side to the position for stacking the sheets the respective one yoke side 5 and 6 of the transformer core 1 are moved and rotated ( Fig. 4g ).
  • the two other turntables 22, 24 is then alternately one of the first packet of sheets corresponding plurality of sheets of a yoke side 5, 6 of the transformer core 1 stacked, the one turntables 21, 23 respectively in the position for stacking the sheets of a leg side 2 and 4 of the transformer core 1 moved and rotated. Thereafter, the method steps described here are also repeated here until reaching the total height of the respective transformer core 1, which likewise has an open e-transformer core (see FIG Fig. 1 ), on whose leg sides 2, 4 and the center leg 3 later the winding is applied (see also description of the first method).
  • a sixth method the method steps as described in the FIGS. 4a - 4g illustrated and described above, the third method. Thereafter, on the two other turntables 22, 24 alternately each one of the first packet of sheets corresponding plurality of sheets of a yoke side 5 and 6 of the transformer core 1 stacked one above the other, now the turntables 21, 23 each in the position for stacking the Be moved sheets of the other yoke side 6 and 5 of the transformer core 1 ( Fig. 4h ).
  • a plurality of sheets of the other yoke side 6 and 5 of the transformer core 1 are alternately stacked on the one turntable 21, 23, respectively, with the other turntables 21, 23 laterally in the position for stacking the sheets the respective other yoke side 6 or 5 of the transformer core 1 are moved ( Fig. 4i ).
  • On the two other turntables 22, 24 is then alternately stacked one after the first packet of sheets corresponding plurality of sheets of the other yoke side 6 and 5 of the transformer core 1, wherein the one turntable 21, 23 respectively in the position for stacking the sheets the one leg side 2 or 4 of the transformer core 1 are moved and rotated ( Fig. 4j ).
  • the method steps described up to here are repeated until reaching the total height of the respective transformer core 1, which then also a closed transformer core (see also Fig. 1 and description of the second method).
  • This seventh method differs from the fifth method only in turn in that the destacking of the center leg 3 is omitted. Otherwise, the process steps of the two methods are identical.
  • the eighth method in which a closed C-transformer core is stacked, also differs from the sixth method only in that the stacking of the center leg 3 is omitted. Otherwise, the process steps of the two methods are identical here as well.
