    When creating chamfers (11, 12) on the edge (4) of a workpiece, such as a glass sheet (1), a grinding wheel (6) is used, which is moved along the edge (4) of the glass sheet (1). In this case, the edges A, B of the edge (4) of the glass pane (1) are machined away by the tool having its working area (9, 10) forming the chamfers (11, 12). If the flat, curved or wavy formed end face (5) of the edge (4) of the glass sheet (1) to the center plane of the glass sheet (1) is aligned obliquely, the tool is aligned along the edge (4) of the glass sheet (1) moves in that substantially identically sized chamfers (11, 12) are formed. For this purpose, the tool is aligned in such a way that the plane of symmetry (13) of the effective regions (9, 10) of the tool does not lie in the center plane of the glass pane (1), ie it has this distance and that the effective regions (9, 10) from the edges (A, B) of the edge (4) of the glass sheet (1) have substantially equal distances.

    The invention relates to a method having the features of the introductory part of claim 1,
    Furthermore, the invention relates to a device with which the method according to the invention can be carried out.
    Definitions of terms used herein: "Tool": A tool by which the edges of edges of a flat workpiece, e.g., a sheet of glass, can be machined to create chamfering, especially a grinding wheel. "Wild areas": The areas of the tool that attack the edge of a surface workpiece. The effective areas of a grinding wheel may be at angles, for example at right angles, to peripheral areas of a circumferential surface formed by straight generatrices (Figures 1 and 7), or a portion of a concavely curved circumferential pool formed by a curved generatrix (Erg 6). Single-shell-shaped regions may be located between effective regions formed by even generatrices on the circumferential surface of a grinding wheel (Fig. 7). " Symmetry plane of effective ranges ": For a grinding wheel, the plane of symmetry of the peripheral surface perpendicular to the axis of the grinding wheel. &Quot; center plane " of the workpiece, in particular the glass sheet: the plane which lies in the region of the edge on which chamfers are produced, centrally between the surfaces of the workpiece. "Face": The plane, dome, or wavy surface of the edge of the workpiece between the edges of the edge of the workpiece (in Fig. 18, the surface between the edges marked Ä and B). " Angle of the face of the edge of the workpiece · ": The angle which a straight line connecting the edges of the edge of the workpiece (straight line between " A " and " B " in Fig. 18) with the workpiece in the region of Edge where chamfers are generated occupies. If the angle is not a right angle, there is a " inclined face " before, " Size of a chamfer ": The size of a chamfer is understood as " chamfer height " (AC or BE in Fig. 18), " chamfer width " (CF or EG in Fig. 18) and " chamfer " (Size of the area bes the area of the edge, which is removed when creating the chamfer (triangle ACF and triangle BEG in Fig. 18), " trimming ": generating chamfers on both edges of a margin of a sheet workpiece, in particular a glass sheet, by discharging material, in particular by roughening. "Roughing": Roughening the end face of the edge of a sheet workpiece, especially a glass sheet, by rubbing. (Roughing the edge of a glass sheet prevents light from being incident on the face surface in the disk surface, causing undesirable reflections.)
    The roughing of an edge of a glass sheet can be done without being trimmed along its edge to produce chamfers.
    It is possible to rough as well as edging an edge of a flat workpiece, in particular a glass sheet. The roughing and trimming can be done with the same tool, immediately after each other with independent tools or in separate operations. Chamfers can be formed with flat boundary surfaces.
    It is also possible to produce chamfers with convexly curved boundary surfaces, whereby chamfers can pass into the end face of the workpiece.
    Such convexly curved chamfers can be produced, for example, by tilting the edge of a fishy workpiece, in particular a glass sheet, with the aid of a grinding wheel guided along the machining edge with concavely curved "knurling". at the periphery surface is processed.
    To produce chamfers, it is also possible to produce V-shaped contact surface grinding wheels (comprising two mutually effective "effective ranges"). If, in addition to creating chamfers, the end face of the edge of a flat workpiece, in particular a glass pane, is too rough, a grinding wheel may be used which has a trapezoidal peripheral surface (comprising two " effective areas ", and therebetween, inferring zy .1. independingly eleven ", ", w rk & c., 1 ch ").
    If only the end face of a flat workpiece, in particular a: glass is too rough, a Abrasive disc with; cylindrical-shaped circumferential area (as " effective area "). Usually, especially when the sheet workpiece is a glass sheet, it is required that the chamfers on both edges of edges are at least substantially equal in size. It is thus undesirable that a chamfer on one edge of one edge is substantially larger than the chamfer on the other edge.
    Producing substantially equal chamfers is not a problem if the end face of the edge is oriented at a right angle to the plane of the sheet (glass sheetS) .In particular, glass sheets produced by fracturing often have faces inclined at an angle to the plane of the glass sheet which deviates from a right angle and which may not be flat, but curved and / or wavy.
    The invention is based on the object of providing a method and an apparatus for carrying out the method, in which it is possible to produce substantially equally large bevels even if the end face of the edge is not at right angles to the plane of the workpiece.
    This object is achieved according to the invention with a method having the features of claim 1.
    Preferred and advantageous embodiments of the method according to the invention are the subject matter of the subclaims.
    As far as the device according to the invention is concerned, the object underlying the invention is achieved with a device having the features of the independent claim directed to the device.
    Preferred and advantageous embodiments of the present invention are dependent claims which depend on the device claim.
    In the method according to the invention, the tool is oriented with its effective range, in particular with its effective ranges, so that even at an angle of the end faces of the edge of the workpiece which is not a right angle ("oblique end face"), substantially equal chamfers are achieved. The tool with its active surfaces is oriented differently than symmetrically to the flank of the workpiece. The tool is oriented so that the plane of symmetry between the effective areas of the tool does not coincide with the median plane of the workpiece (glass sheet). In accordance with the invention, the tool is oriented so that it produces at least substantially equal chamfers at the edges of the edge, even with a slanted end face of the edge of the workpiece.

    In the following, when discussing the embodiment examples shown in the drawings of a glass sheet as a flat workpiece, this is not to be understood as limiting in principle that, with the method according to the invention and the device according to the invention, other p. f 1 e c h. i q e ") W e rk s t o c k e as G l a s c h e i n e a τ 'b e .1. t e t w e r d e k ο η n n.
    In all depictions, the invention will be explained by way of example with reference to a rim 4 of a vertically standing glass pane 1. At the other edges of the glass 1 and. in the case of a non-perpendicular glass pane 1, appropriate proportions are present.
    In the description, the direction of the longitudinal extent of the edge 4 is referred to as the X direction. The direction normal to the surfaces 2 and 3 of the glass sheet 1 (z "B. plane of the glass sheet 1) is referred to as the Z direction. A direction perpendicular to the edge 4 of the glass sheet 1 is referred to as Y ~ direction.
    When constructing curved chamfers (Figure 3), the
    Mater! a labt rag be driven so far 'that the end face 5 of the edge 4 of the glass sheet 1 disappears and the chamfers merge into each other. For example, it is shown in Figs. 4 and 5, in which case a " edge trim " spoken.
    A grinding wheel 6 with a concave contact surface Sals tool has, for example, the shape shown in FIG. 1 with a contact surface 8, which has two active regions 9 and 10 aligned with one another in a V-shape. With the grinding wheel 6 ', the edges of the edge 4 of the glass sheet 1 are eroded ("trimmed"), resulting in bases 11 and 12.
    In this case, the grinding wheel 6 is moved in the X direction along the edge 4 of the glass pane 1 and rotated about its axis 7.
    More valuable embodiments of grinding wheels 6 are shown in FIG. 6 (concavely curved contact surface 8 comprising an effective region), FIG. 7 (trapezoidal area of action) and Fig. 8 (zyiindermantförmige trained effective range) shown.
    The grinding wheel 6 shown in FIG. 8 is used in particular for roughening the end face 5 of the glass pane 1, wherein the edges are not broken, ie no chamfers 11, 12 are formed.
    To the. entire edge 4 of a glass pane I, d. H. to machine all its edges 4, the grinding wheel 6 performs a relative movement around the glass sheet 1 around.
    For this purpose, either the grinding wheel 6 can be guided around the glass pane 1 or the glass pane 1 is guided along the entire edge 4 along the grinding wheel 6. Also drawn is a combination of movements of the grinding wheel 6 and the glass pane. 1,
    In the context of the invention, it is also contemplated that machining the edges of a glass sheet 1 is performed not only with one, but with more than one, for example, two grinding wheels 6. With more than one grinding wheel 6, the machining of the edges i of a glass pane 1 can be carried out partly simultaneously, partly successively.
    Equal chamfers 11, 12 at the edges of a rim 4 of a glass sheet 1 are readily achieved when the end face 5 (more precisely a (defined) plane passing through the edges of the rim i, because the end face 5 is not evenly flat, but also curved or corrugated can be) is a plane that is normal to the surfaces 2, 3 of the Glasscheibe1 aligned. In this case, the grinding wheel 6 is aligned symmetrically with respect to the median plane of the glass sheet 1 (plane lying midway between the surfaces 2, 3 of the glass sheet 1 and being parallel). This orientation of the grinding wheel 6 to the glass pane 1 is shown in FIGS. 1, 6 and 7
    Ci C h. C -L C.j .. t
    However, a symmetrical alignment of the effective regions of the grinding tool with the center plane of the glass pane only results in chamfers II and 12 of equal size if the angle of the end face 5 of the edge 4 at least to the surfaces 2, 3 of the glass pane 1 is approximately normal, ie a right angle ,
    Glass shards 1 are made by splitting a larger glass sheet. This will be the Glastafein after the
    Splitting pattern and then broken along Rrtzlinien. This often produces edges i whose (plane or
    curved) faces 5 to the surfaces 2, 3 of the glass X are inclined. This is shown schematically in FIG. 15, for example.
    The amount of inclination of the end face 5 of the edge 4 of the glass shard 1 may vary over the length of the edge 4.
    When a sheet of glass 1 having a rim 4 as shown in Fig. 15, that is, a slit end face 5 is machined with a symmetrically oriented grinding wheel 6 (shown in solid lines in Fig. 1.6), chamfers 11, 12 of different sizes are obtained.
    According to the invention, the position of the grinding wheel 6 relative to the glass shard 1 from the symmetrical alignment by the offset Vu, adjusted, so the grinding wheel 6 from its to
    Glass pane 1 moves away from symmetrical alignment (centered positioning), and picks up. in big. 16 and 1'7 indicated in stri.chliert.enLinien position to the glass pane 1 a.
    By varying the position of the grinding wheel 6 in the Z-direction (normal to the plane of the glass sheet 1 and parallel to the axis of rotation 1 of the grinding wheel 6) it is achieved that much of the glass is removed from both edges, so that approximately large bevels 11, 12 are formed become.
    Incidentally, the offset V, 2 of Figs. 16 and 17 can be achieved by changing the position of the grinding wheel 6 and / or changing the position of the glass sheet 1 in the Z direction, respectively.
    If, after changing the position of the grinding wheel 6, both edges of the edge 4 of the glass sheet 1 are formed to be too large or too small chamfers 11, 12, the grinding wheel 6 can also be displaced in the Y direction by moving away from the edge 4 or towards the edge 4 becomes (offset V: >, in Fig. 17). For example, as the grinding wheel 6 removes a chamfer of the correct size at the position shown in FIG. 16 in FIG. 16, the displacement of the grinding wheel 6 is offset by the offset V5a, ie in the position shown in dashed lines in FIG lead to the fact that on both edges too large bevels 11, 12 would be formed. To take this into account, the grinding wheel 6 is displaced by the distance V · ,; from the position shown by dashes in Fig. 17 to the position shown by solid lines in Fig. 17.
    In Fig. 18, a glass sheet 1 and a grinding wheel 6 are shown in the line of Fig. 17 (solid lines). The points A and B correspond to the edges of the edges 4 of the glass sheet 1 before trimming. The connection of the points C and F corresponds to the chamfer 11 on one edge and the connection of the points E and G of the chamfer 12 to the other cart.
    The extent of offset V, 2. (Figure 16) and the offset V23 (Figure 17) can be calculated from the measured position of the edges A and 3 at which lands are to be created.
    In the context of the invention, it is contemplated that, during the movement of the grinding wheel 6 and / or the glass sheet 1, when making chamfers 11, 12, the offset V ,, and / or Vr, respectively, the size of the angle of the grinding wheel 6 at the location of the attack of the grinding wheel 6. End face 5 is adjusted.
    The invention also relates to a method (and to a device) with which the position of the edges A, B at the edge 4 of a glass sheet 1 is determined. Based on this, the position of the grinding wheel 6 relative to the glass sheet 1 is selected. For example, a uniform trimming of the edges A, B of the edges 1 of a glass pane 1 in the sense of constant dimensions of the chamfers 11, 12 can be achieved. This can also be continuously achieved by continuously readjusting (adjusting) the position of the grinding wheel 6 relative to the glass sheet 1, taking into consideration the position of the edges A, B of the bands 1 of the glass sheet 1, the desired size of the chamfers 11, 12.
    Within the scope of the invention, it is also contemplated that the grinding wheel 6 is inclined by an angle j about an axis extending in the X-direction; to pivot to adjust the position of the grinding wheel 6 of the position of the edges on the edge 4 of the glass sheet 1 to be processed. In this case, the plane of symmetry 13 between the angular regions 9 and 10 to the center plane of the glass sheet 1 is skewed. The angle h can be set so that, after pivoting the grinding wheel 6 by the angle ψ, the plane of symmetry 13 between the active surfaces 9 and 10 of the grinding wheel 6 is normally aligned with the end face 5 (between the points A and B of Fig. 18). The determination of the angle ψ is especially in the construction of the end face 5 of the
    Edge 4 of a glass sheet 1 'advantageous, as shown in Fig. 19 beispielbeispielhaft. For the continuous adjustment of the offset VLJ and V23, separate actuators (drives) may be provided.
    The continuous adjustment of the offset can also be carried out by a drive which also carries out the pelative movement of grinding wheel 6 and glass pane 1,
    The continuous adjustment of the offset V5S may also be performed by a drive which serves to adjust the position of the grinding wheel 5 to the thickness of the glass sheet 1. For determining the position of the edges (symbolized by " A " and " B " in Fig. 18) of a rim 4 of a glass sheet 1, various methods can be adopted. For example, optical or image recognition methods, in particular also mechanical scanning methods, are advantageous. For example, the edges A, B of a rim 4 of a glass sheet 1 may be used by keys sliding along the edges A, B, for example, attached to hollow beams or formed as springs. The preferred mechanical scanning in the context of the invention with the aid of two leaf springs is particularly easy to implement in terms of apparatus.
    Such a scanning device is shown partially and schematically in Figs. 20, 21 and 22, wherein Figs. 20 and 22 are perspective views and Fig. 21 is an end view of the scanning device. In Fig. 20, the tool (grinding wheel 6) for forming the chamfers 11, 12 is not shown, and therefore, in Fig. 20, the chamfers 11, 12: are also not shown.
    The position of the edges A, B of the edge 4 detecting probes 20, 21 are in the embodiment shown leaf springs, the (elastically biased) resiliently abut the edges A, B of the edge 4 of the glass sheet 1, whose position is to be determined. The buttons 20, 21 are fixed at one end (not shown) support, while they slide in the region of their free movable ends 22, 23 along the edges of the edge 4 of the glass sheet 1. The probes 20, 21 are oriented towards each other (see Big, 21) in such a way that they assume the angles α and β (see Fig. 21) with respect to the surfaces 2, 3 of the glass sheet 1. These angles c and ß amount to about 45 °. It means that the buttons 20, 21 to each other assume an angle y, which corresponds approximately to a right angle.
    In FIGS. 20 and 21, the situation is illustrated in solid lines in the case of a glass pane 1 whose end face S is substantially perpendicular to the plane of the glass pane 1 (right angle of the end face 5) and in broken lines the situation in which the end face 5 is facing the plane of the glass pane 1 is set at a non-right angle, that is obliquely (" oblique face ").
    The buttons 20, 21 are located on the edges I and B, respectively, so that assuming that the position of the planes corresponding to the surfaces 2, 3 of the glass sheet 1 is constant and known, the position of the buttons 20, 21 on the position of the Edges ä, B can be closed. The location of the buttons 20, 21 can be determined by means of displacement sensors 24, 25 (Figure 21) mounted on the support of the styluses 20, 21. For the path sensors 24, 25, different measuring principles are used, in particular the measurement can be carried out contactlessly with the aid of an inductive sensor: The scanning can be done in both directions of movement of the grinding wheel 6, as indicated by the arrow 26: in Fig. 20 and the arrow 27 in Fig. 22. In the Hegel, however, the grinding wheel 6 is located, relative to the direction of movement, behind the scanning device is the buttons 20, 21 (see FIG.
    For example, when the defrosting device is used in the direction of the arrow 27 (FIG. 22), the grinding wheel G is disposed on the side of the free (movable) ends 22, 23 of the buttons 20, 21. In this case, the outer tabs 20, 21 have the further advantage that they may be concavely curved and form a channel through which cooling liquid common to grinding is fed via leads 30, 31 can. This is indicated schematically in FIG. 22.
    The above-described determination of the position of the edges Ά, 3 with the aid of the buttons 20, 21 assumes that the position of the surfaces 2, 3 of the glass pane 1 is constant or known. If this is not the case, the position of the surfaces 2, 3 of the glass panes 1 in the vicinity of the edges A, B of the edge 4 to be processed can be determined with the aid of a further scanning device. For example, the position of the surfaces 2, 3 of the glass pane X, as well as this is shown in FIG. 23, can be determined with the aid of two scanning rollers 32, 33. Instead of the scanning rollers 32, 33 and resilient buttons 20, 21, as shown in FIGS., 20 and 21 for the scanning of the edges A, B dargestelit be used.
    In summary, an embodiment of the invention can be described as follows:
    When producing chamfers 11, 12 at the edge 4 of a workpiece, such as a glass sheet 1, a grinding wheel 6 is used, which is moved along the edge 4 of the glass sheet 1. In this case, the edges A, B of the edge 4 of the glass pane 1 are machined by the tool having its circumferential areas 9, 10 with the chamfers 11, 12 forming. When the end face 5 of the edge 4 of the glass sheet 1, which has been curved in a straight line, is aligned obliquely with respect to the median plane of the glass sheet 1, the tool is moved along the edge 4 of the glass sheet 1 so as to be in alignment
    Essentially equal sized chamfers 11, 12 are formed. The tool is aligned for this purpose so that the syrametric plane 13 of the effective regions 9 > 10 of the tool is not in the center plane of the glass sheet 1, that is from this distance and that the effective areas 9, 10 of the edges A, B of the edge 4 of the glass pane 1 have substantially equal distances
