Definitions

  • the invention relates to a method for producing a stack of sheets, in particular sheets, which are free of guide holes and / or in particular of transformer sheets.
  • the invention also relates to an apparatus for producing a stack of sheets, in particular sheets, which are free of guide holes and / or in particular of transformer sheets, wherein the apparatus comprises a stacking table and above the stacking table horizontally adjustable stop elements, which are designed and intended to be placed laterally sheets.
  • the invention relates to a stack of sheets, in particular of sheets, which are free of guide holes, which is produced by a method according to the invention and / or with a device according to the invention.
  • the prior art discloses methods and apparatus for producing a stack of plates, in particular a transformer core.
  • a device for coating plates provided with guide holes for aligning each plate with a predetermined position.
  • a horizontal base is provided to stack the plates.
  • a conveyor sequentially advances the plates to a predetermined position above the horizontal base, the plates falling from the predetermined position on the conveyor to the horizontal base to laminate the plates.
  • guide means with guide pins which move together with the falling plate to engage the corresponding guide holes.
  • a device for holding stacked sheets, in particular transformer sheets is known.
  • the sheets have a thread hole, so that they can be aligned by means of a threading bolt.
  • a stacking device for transformer sheets having thread holes is also made DE 25 06 681 A1 known.
  • the stacking device has height-fixed threading bolts, which engage in the thread holes of the transformer sheets during the stacking process.
  • DE 21 63 700 a method for laying laid of individual sheets cores for transformers, inductors and the like, in which an already stored sheet itself serves as a stop for further sheets to be deposited.
  • This embodiment has the disadvantage that no great accuracy with regard to the positioning of the individual sheets can be achieved. This is particularly because the edges of the sheets, which also serve as a stop for further sheets according to this method, usually have dimensional inaccuracies of a few tenths of a millimeter, as well as protruding burrs.
  • DE 2551 497 discloses a device in which a core sheet is deposited on a stack. To remove the core sheet, a clamping caused by brake strips and guide rails is achieved. After releasing the clamping, the core sheet drops onto the stack with the fall of the core sheet passing through the funneling power.
  • the further object is achieved by a device which is characterized in that the stop elements are formed and positioned such that they exclusively define a plurality of horizontal desired positions for a plurality of sheets to be deposited in the same horizontal plane.
  • the stop elements are positioned such that each of the plurality of horizontal desired positions is determined without mechanical overdetermination.
  • precise positioning is possible only when the setpoint position is reached by the stop elements is defined such that the sheet to be deposited can come to rest only in this one desired position.
  • each of the plurality of horizontal desired positions is determined directly and exclusively by the stop elements.
  • This embodiment has the particular advantage that one relies only on the stop elements whose position is known exactly, while on the use of other attacks, such as the use of the side edges or the corners of already deposited sheets can be completely dispensed as a stop. This achieves a particularly high precision.
  • At least one sheet to be deposited is provided with a lateral recess, for example with a lateral notch and / or a lateral indentation, into which a stop element during depositing of the sheet at least partially intervenes.
  • a lateral recess for example by a milling process-takes place with particularly great accuracy such that the recess has little, in particular none, imperfections, such as protruding burrs or measurement inaccuracies.
  • the lateral recess for example the notch or the indentation
  • the effort required to produce a precise notch or a precise indentation is very limited.
  • a precise reference is thereby created on the sheet to be deposited, which allows a very accurate positioning of the sheet.
  • a stop element has a projection-preferably rounded-which engages in a notch or indentation during the depositing process.
  • the desired position is already determined by the engaging in the notch or indentation projection in the manner that the sheet is still free in the horizontal plane only in terms of its angular position.
  • an additional stop is provided in an advantageous embodiment, which effectively prevents horizontal rotation of the sheet around the projection which engages in the notch. In this way, the target position of the sheet is defined clearly and without overdetermination.
  • the stack is formed from layers, each having a plurality of juxtaposed and spaced apart sheets.
  • the fact that the sheets are spaced apart in the storage position, is achieved in an advantageous manner that it does not come to inaccuracies, for example, because of abutting, protruding ridges on the individual sheet edges. It has been shown that a very good positioning accuracy can be achieved if the distance between adjacent plates is less than 0.5 mm, in particular less than 0.3 mm. In particular, it is advantageous if the spacing of adjacent sheets is in the range of 0.1 mm to 0.3 mm, in particular 0.2 mm.
  • the method according to the invention it is possible to produce stacks which are formed from staggered layers and / or those within the layers have different sized and / or differently shaped sheets.
  • the stop elements are positioned differently for the deposition of a new layer of sheets than in the previous layer of sheets.
  • every possible shaping of sheet metal stacks is possible according to the invention.
  • the vertical relative positioning takes place in that the stacking table is moved downwards in each case after the process of depositing, preferably by a distance corresponding to the thickness of the previously deposited sheets.
  • Such a design has the particular advantage that the required horizontal adjustability and the required vertical adjustability are decoupled from each other in such a way that only the stacking table must be movable in the vertical direction, while the stop elements must be movable only in the horizontal direction.
  • the complexity of the overall structure is drastically reduced. This particular because it can be dispensed with a vertical adjustability of the stop elements and a horizontal adjustability of the stacking table.
  • the sheets are brought from above into the desired position.
  • the relative positioning of the stacking table and / or the positioning of the stop elements and / or the deposition of the sheets takes place automatically and / or computer-controlled.
  • the sheets to be deposited are cut out of a sheet metal material and / or punched and then immediately after the cutting or punching - spent without viteablegen - in their desired position.
  • This design is particularly efficient both in terms of space requirements, as well as in terms of workload.
  • On the one hand can be dispensed with an intermediate storage.
  • Such an embodiment can be realized, for example, in the manner in which a cutting or punching system is controlled in such a way that - in terms of shape and size - the sheet is produced which is to be deposited next and / or which can be attached immediately to the row of sheets to be deposited is.
  • a stack produced according to the inventive method and / or apparatus with a device according to the invention has the advantage that it can be free of guide holes.
  • the fact that the individual sheets may have small lateral notches or indentations used for accurate positioning is generally irrelevant to the distribution of the magnetic field. This particular because the notches or indentations are small compared to the size of the sheet and in particular laterally - not like guide holes in the central region - are arranged.
  • lateral notches or indentations has the further advantage that a stop element engaging there can be designed and shaped such that-unlike a guide pin in a guide hole-a very precise abutment position is defined.
  • a stack of sheets which is produced according to the method according to the invention and / or with a device according to the invention can be constructed according to the invention in such a way that the stack is formed from layers which each have a plurality of sheets arranged next to one another and spaced from one another.
  • the distance between adjacent plates is smaller than 0.5 mm, in particular less than 0.3 mm, in particular in the range of 0.1 mm to 0.3 mm, in particular about 0.2 mm.
  • Fig. 1 shows a processing apparatus 1 with a device 2 for producing a stack of sheets and with a cutting and punching device 3 for cutting and punching to be deposited sheets.
  • the cutting and punching device 3 is precisely made in each case in terms of size and shape, the sheet to be added next to the series of sheets to be deposited. After the production of a sheet to be deposited, this is transported to the device 2 for producing a stack of sheets with a transport device 4, which has magnetically operating transport gripper 5.
  • the apparatus for producing a stack of sheets is shown only schematically in this figure.
  • the device 2 for producing a stack of sheets has a height-adjustable stacking table 6, on which the sheets are deposited.
  • Fig. 2 to 8 are individual steps of a method according to the invention for producing a stack of sheets which are free of guide holes, shown schematically.
  • Fig. 2 shows a section of a device 2 according to the invention for producing a stack.
  • the horizontally adjustable stop elements 7 are mounted at a fixed height.
  • the stacking table is positioned vertically relative to the stop elements such that sheets deposited on the stacking table lie at the same vertical height at which the stop elements 7 are located.
  • the stop elements 7 consist of small round projections which are attached to support rods 8.
  • the vertical relative positioning of the stacking table relative to the horizontally adjustable stop elements is in the side view of Fig. 3 well illustrated. It can be clearly seen that the stop elements 7 are arranged directly above the stacking table 6.
  • the horizontal positioning of the horizontally adjustable stop elements 7 is now carried out in such a manner that a plurality of horizontal desired positions for a plurality of sheets to be deposited are completely defined exclusively by the stop elements 7.
  • the sheets to be deposited 11 are stored by the transport grippers 5 in the specified positions 10, the sheets are guided laterally when depositing the stop elements.
  • the stacking table 6 is moved downwards by a distance corresponding to the sheet thickness of the deposited layer. Subsequently, the horizontally adjustable stop elements are positioned so that they completely set a plurality of horizontal target positions for several sheets to be deposited next layer. This is in Fig. 5 shown. Subsequently, the sheets of the next layer are deposited.
  • Fig. 6 shows the thus growing stack 12 of stowed sheets 11. It is clearly seen that the stack has on its outer contour in the lower region of an increasing diameter staircase and in the upper part has a decreasing in diameter staircase. This situation is in Fig. 7 shown in perspective. After the stack 12 is completely made, the stacking table is moved down to expose the finished stack and transported away.
  • Fig. 9 shows a detailed view of positioned sheets 11. It can be clearly seen that the sheets 11 are spaced from each other. In particular, one sheet 11 does not serve as a stop for another sheet 11. One of the sheets 11 has a precise notch 13 into which a stop element 7 rounded in its end region engages. There is another stop element 7 arranged on the opposite edge of this sheet, so that the target position of the sheet is completely defined by the stop elements 7.
