Definitions

  • the invention relates to a method according to the preamble of claim 1 and to an apparatus for performing the method according to the preamble of claim 9.
  • the layered cores for distribution and power transformers with outputs of more than 30 KVA are still layered by hand.
  • a further rationalization effect is achieved if the individual sections on a stacking station are already provided in stacks in the correct relative position to one another and if each individual section of a layer is transported together from the stacking station to the positioning station. In this way, all individual sections of a layer can be fed to the positioning station with a single movement, which allows the use of a gripper system. Obviously, this is much easier than feeding with conveyor belts, roller conveyors or robot systems.
  • a single layer can be positioned particularly easily on the positioning station if an individual section is fixed in a predetermined position or aligned on a predetermined axis and if all other individual sections of a layer are positioned by pushing, the fixed or aligned individual section being the position of all pushed individual sections determined. This means that no holes are required to position the individual sections. Length tolerances of the individual sections are automatically compensated for, since the individual sections are always pushed against each other up to the stop. This reliably prevents air gaps at the joints. In this way, three-phase transformers with three parallel legs and two yokes can be layered particularly advantageously by first aligning the middle leg on a predetermined axis at the positioning station and then pushing the two yokes and the two outer legs.
  • the butt joints can be blunt, mortised or bevelled.
  • a teaching yoke can also be provided at the positioning station, which yoke always remains at the positioning station and only serves to align the remaining individual sections. A layer that is open on one side is thus transported from the positioning station to the layer station and piled up to form a core that is open on one side.
  • the individual layers are transported from the stacking station to the positioning station, preferably with a movable gripper, which bends the ends of the individual sections when they are lifted off the stack. In this way, the relatively strong adhesive force can be overcome when lifting the individual sheets from the stack. Moving lifting from the stacking station does not have a disadvantage since the individual sections do not have to be placed in an exact position on the positioning station.
  • the completely positioned layer is transported from the positioning station to the layer station with a rigid gripper, which guarantees an exactly plane-parallel transport without moving the butt joints. A plane-parallel lifting without the occurrence of adhesive forces from the positioning station is made possible in that the positioning station has a support table with a structured surface.
  • Positioning on the positioning station is particularly easy to implement if it has a support table with grooves and if the push-on device consists of push-on elements which protrude from the support table through the grooves and are displaceable in the grooves.
  • the push-on device is arranged essentially under the support table, so that there are no disruptive machine elements next to or above the positioning station.
  • Two interacting push-on elements are preferably attached to a parallel running rope, so that an axially symmetrical movement of the push-on elements relative to or away from one another is possible.
  • the positioning station preferably has a hold-down device with which the bent-up ends of the individual sections can be held down when the individual sections are pushed. This reliably prevents any bent ends of individual sections from lying on top of one another when pushed.
  • the hold-down device is advantageously integrated directly into the gripper between the positioning station and the shift station.
  • a particularly high degree of automation can be achieved if four grippers are attached at an angle of 90 ° to each other on a rotating unit that can be rotated about a vertical central axis, and if two positioning stations and each are offset around the central axis by 90 ° a stacking station and a shift station are arranged, the two positioning stations being diametrically opposite one another.
  • the transport from the stacking station via the positioning station to the shift station takes place in a constant reciprocal reciprocating movement, a shift always being fed and positioned on a positioning station and being lifted off again at the next but one cycle and being transported further. Every single pendulum movement therefore fulfills a function.
  • a further optimization of the production can be achieved if different stacking tables can optionally be fed in at the stacking station. In this way, the prepared stacks can be automatically fed to the various stages of a core cross-section on different tables. This makes it possible to produce multi-stage cores practically fully automatically without downtimes for retrofitting etc.
  • the various individual sections 3 are first provided in stacks on a stacking station 5.
  • the stacks are already in the correct position relative to each other, but are not absolutely exactly aligned.
  • the individual sections 3 of a layer are lifted together from the stacking station and placed on the positioning station 4. As indicated by dot-dash lines, these individual sections have the same relative position to one another after being deposited as on the stacking station 5.
  • the individual sections of the layer on the positioning station are then pushed against one another until the layer forms a self-contained structure.
  • an individual section for example a middle leg, is preferably fixed or at least aligned on a specific axis, while all the remaining individual sections are pushed on.
  • the fully positioned individual layer is then closed by the positioning station 4 transported to the shift station 2 and deposited there exactly, or stacked to form a layer body 1. Lateral moments of force no longer act on the already layered individual layers, since the individual sections no longer have to be positioned.
  • the exact placement of the positioned individual layers on the shift station can be achieved with simple means.
  • the method is particularly advantageous for the layering of transformer cores, especially three-phase transformers.
  • transformer cores especially three-phase transformers.
  • other laminates can also be built in the same way as they are used in construction or mechanical engineering.
  • Various configurations are also conceivable for the configuration of the transformer cores.
  • a multi-stage core of a three-phase transformer can be layered, as shown in FIGS. 2 and 3.
  • single-phase transformers of the core or jacket type or even more complicated five-leg transformers can also be produced.
  • the core cross sections can obviously also be modified as desired.
  • core cross sections can also be realized with cooling slots.
  • the butt joints of the individual sections can be blunt or mortised, the ends of the individual sections being cut at right angles or at an angle.
  • FIGS. 2 and 3 show, for example, a typical core 6 of a three-phase transformer with a stepped cross section, which is composed of the middle leg 12, the two outer legs 13 and the two yokes 14. The ends of the individual sections are cut at an angle of 45 °.
  • the cross section of the core is five-stage and is composed of the first and fifth stages 7 and 11, the second and fourth stages 8 and 10 and the middle and third stages 9.
  • FIGS. 4 and 5 show the arrangement of the individual sections of two successive layers in more detail.
  • the individual successive layers are stacked offset from one another.
  • the middle leg 12 has a leg tip 19 which is arranged offset by the dimension a from the central axis 20.
  • the yokes 14 are provided with a V-cut 15, which is arranged in the middle of a yoke. When the yokes 14 are pushed onto the middle leg 12 with the offset leg tips 19, the simplest way is that the joints of the yokes with the outer legs 13 also have an offset.
  • FIG. 4 shows a layer with the upper yoke offset to the left relative to the central axis 20.
  • the middle leg 12 is arranged in the opposite direction, so that the tip 19 of the leg is offset by the dimension a to the right of the central axis 20. This accordingly results in an upper yoke 14 shifted to the right.
  • a core consists of shifted layers according to FIGS. 4 and 5. This mutual construction of the core is known per se and is no longer explicitly mentioned in the explanations below.
  • Figure 6 shows the processes involved in positioning a layer for a three-legged core.
  • the positioning is carried out with push elements 21 which are displaceable in grooves 22.
  • the individual sections have their basic position, which corresponds to the position on the stacking station 5 mentioned above.
  • the middle leg 12 is aligned and held on the axis of symmetry Y with the aid of the push-on elements 21, as shown in FIG. 6b.
  • the middle leg can move freely in the Y-axis, which may be due to rolling elements on the shank elements is made easier.
  • the two yokes 14 are pushed with an axially symmetrical movement relative to the axis of symmetry X and with a certain force against the middle leg 12 up to the stop.
  • the layer is now aligned with both the Y and X axes.
  • the outer legs 13 are also individually struck against the yokes 14 with a parallel movement relative to the axis of symmetry Y. Tolerance fluctuations in the length of the various individual sections are automatically compensated for, so that gap-free joints occur.
  • the layer which has been positioned in this way is then fed to the layer station for layering the core using a suitable device.
  • FIG. 7 shows the process for positioning a layer for the production of a core that is open on one side.
  • a teaching yoke 17 is arranged on the positioning station, which takes on the function of the second yoke.
  • the push-on elements 21 engage in longitudinal slots 23, so that a lateral movement of the yoke relative to the axis of symmetry Y is possible.
  • FIG. 7a shows, the individual sections are first placed back on the positioning station.
  • the middle leg 12 is then aligned and held in the Y-axis, as shown in FIG. 7b.
  • the teaching yoke 17 is then first moved into position.
  • the teaching yoke in the slots 23 can move to the left or to the right.
  • the yoke 14 is pushed onto the middle leg 12 parallel to the X axis with a certain force.
  • the two outer legs 13 are again pushed in parallel, as shown in FIG. 7e.
  • the yoke obviously remains on the positioning station, so that a core open on one side is stacked on the layer station.
  • the positioning station 4 has a support table 24 which is provided with grooves 22 in which the push-on elements 21 projecting beyond the table can be displaced.
  • FIG. 8 shows a cross section through a single groove with an individual section 3 lying on the support table 24.
  • the individual push-on elements 21 are pivotally mounted on an axis 26, which in turn is fastened to a push-on carriage 25.
  • the push-on elements 21 are prestressed in the push-on direction with a spring 31 and can be adjusted with a stop screw 27.
  • the push-on carriages 25 are fastened to a parallel running rope 28 and move on rollers 30 on a linear guide 29.
  • the parallel running rope 28 is tensioned by means of deflection rollers 33.
  • a push-on carriage 25 and 25auf is attached to each stretched section of the parallel running rope.
  • the two push-on carriages 25 and 25 ⁇ obviously move towards or away from each other. This achieves an axially symmetrical movement which is used to push the sheet metal sections.
  • the parallel rope 28 is driven by a drive rope 36 which is tensioned parallel to the parallel rope 28.
  • This drive cable 36 is driven via a drive wheel 37 by a motor, not shown, at a constant speed.
  • the connection between the drive cable 36 and parallel running cable 28 is established via a driver 34, which is connected to the parallel by means of a cable clamp 35
  • Running rope 28 is attached.
  • the driver 34 is resiliently mounted relative to the drive cable in that a spring 40 is arranged between the cable clamp 63 on the drive cable 36 and the driver 34.
  • the drive cable 36 is guided through a bore 64 on the driver 34.
  • the spring 40 can be preloaded with the rope clamp 65. With the cable clamp 63 fixed to the drive cable 36 is a cam 38 with which a switch 39 on the driver 34 can be activated.
  • the driver 34 pulls the parallel running rope 28 in the direction of arrow A, so that the two push-on carriages 25 and 25 ⁇ move towards one another.
  • the pushing carriages 25 and 25 ⁇ are braked by tensioning the springs 31 on the pushing elements 21.
  • the driver 34 moves relative to the drive rope 36, which continues to run.
  • the spring 40 which has a smaller spring constant than the springs 31, is pressed together until the cam 38 actuates the switch 39. This brings the drive wheel 37 to a standstill.
  • a measuring device 32 is preferably actuated, as is indicated schematically in FIG. 9. It can be an incremental or an absolute measuring system.
  • the position of the push-on elements 21 is determined with the measuring system and passed on to a control device.
  • the control device compares the determined values, for example the width of the middle leg and the position of the yoke and side leg pushers with predetermined values and triggers an interference signal if there are deviations between the actual dimension and the target dimension.
  • the drive wheel 37 is reversed until the push-on carriages 25 and 25 ⁇ have reached an opening position determined by the measuring system 32.
  • the drive wheel 37 is then stopped and the positioning station is ready for a further pushing operation.
  • FIG. 10 shows the combination of several parallel running ropes, as is required, for example, for the push-on process shown in FIG. 6.
  • 41 and 41 ⁇ the two cables for pushing the outer legs are shown.
  • the only difference from the parallel running rope shown in FIG. 9 is that the two push-on elements 21 do not move parallel, but diagonally towards one another, but parallel to the X axis.

  • the push elements 21 of the cables 41 move in the direction of arrow B.
  • Position 42 shows the cable pull for the middle leg.
  • two push-on elements 21 are fastened in pairs on a push-up carriage 25 via the axis 26 and move in pairs towards or away from each other in the direction of arrow C.
