Definitions

  • the invention relates to a receiving device for a spectacle lens according to the preamble of claim 1 and its use for inserting and removing the spectacle lens in or from a container and / or for attaching and removing to or from a spectacle lens holding shaft of a spectacle lens edge processing machine by means of a handling device.
  • a receiving device according to the preamble of claim 1 is e.g. known from JP-A-60 056863.
  • a raw glass is first inserted into an opto-electronic recognition device using a handling device, which has an electronic image processing and evaluation system for recognizing common markings such as dots, crosses, notches on the edge of the raw glass or the location of an existing near part.
  • Signals are transmitted from the electronic image processing and evaluation system of the optoelectronic detection device to a control device for the handling device, so that the raw glass can be inserted into a holder, in particular a spectacle lens holding shaft of a spectacle lens edge processing machine, by means of the handling device.
  • the handling device has a movable receiving device with a single suction device for introducing the raw glass into the detection device and a plurality of suction cups arranged in an arc shape for transferring the raw glass from the detection device into the spectacle lens edge processing machine.
  • the suction cups are arranged on a ring segment which can be rotated relative to the receiving device and whose axis of rotation is perpendicular to the individual suction cups.
  • a raw glass can be gripped in the area of the edge and placed on a three-point support of the optoelectronic detection device on or in the spectacle lens holding shaft of the spectacle lens edge processing machine, the central area around the optical axis of the raw lens for attaching the soft elastic head on the swivel arm of the opto-electronic recognition device or for insertion into the lens holding shaft in the lens processing machine remains free.
  • the suction cups can be subjected to negative pressure to hold the raw glass.
  • the central suction device on the receiving device serves to remove a raw glass from a container remove and place on the three-point support of the opto-electronic detection device, while the suction cups arranged on the ring segment grip an eyeglass blank from above or below on the three-point support and insert it into the spectacle lens holding shaft, which ensures that there is no obstruction by the guide rod with the soft elastic Head or through the lens holder shaft.
  • a raw lens can also be inserted into the spectacle lens holding shaft by means of the central suction device if it is ensured that the raw lens is first held on one side on the spectacle lens holding shaft and if the spectacle lens holding shaft can be moved apart so far that the receiving device is in move this area and a raw glass can also be used with this sucker.
  • the invention is based on the problem of creating a receiving device which is suitable for receiving a spectacle lens by means of a central suction device and inserting it precisely into a spectacle lens holding shaft, in particular axially with respect to the optical surface of the raw lens opposite the receiving device, this receiving device thus should be designed so that it can be used with conventional spectacle lens edge processing machines, the spectacle lens holding shaft need not be adapted to the receiving device.
  • This problem is solved unit of the receiving device according to claim 1.
  • Such a holding device can be used for inserting and removing an eyeglass lens in or from a container and / or for attaching and removing it to or from an eyeglass lens holding shaft in an eyeglass lens edge processing machine by means of a handling device that holds the base (claim 7).
  • the spherical cap is placed on an optical surface of a raw glass with negative pressure applied, it adapts to any angular position of this optical surface, while the opposite optical surface maintains its position. If the vacuum is switched on, the raw glass is held in the sealing area at the edge of the spherical cap, while the spherical cap is pulled against the ring surface of the recess in the base and is held in this position due to the friction between the ring surface of the recess and the complementary surface of the spherical cap.
  • the raw glass can be removed with its free one Place the surface in the correct position and exactly coaxial to the axis of this lens holding shaft and fasten it there in a suitable manner. This can be done in such a way that the raw lens with the free optical surface is moved directly against a clamping sleeve that can be subjected to negative pressure on this half of the spectacle lens holding shaft and is held by applying negative pressure.
  • the optical surface of the raw lens opposite the receiving device in a centering device with a customary block or suction device, which can be inserted precisely and coaxially into a corresponding clamping sleeve on the corresponding half of the spectacle lens holding shaft.
  • a customary block or suction device which can be inserted precisely and coaxially into a corresponding clamping sleeve on the corresponding half of the spectacle lens holding shaft.
  • an additional negative pressure can be applied to the clamping sleeve in order to increase the holding force.
  • the annular surface of the depression in the base can be designed such that there is a linear contact with the surface of the spherical cap.
  • the spherical cap can advantageously be movably attached to the base by means of a mushroom-shaped holder which is guided through the opening, so that it cannot be lost when the negative pressure is released.
  • the spherical cap can be made entirely of an elastic plastic material, but preferably has a soft lip seal in the sealing area, which ensures a good adaptation and sealing to a non-spherical optical surface of the raw glass.
  • the dimensions of the base with the spherical cap arranged therein are only insignificantly larger than those of a conventional block or suction cup, so that the receiving device according to the invention with a raw glass can be moved easily into the region of the halves of the spectacle lens holding shaft that have moved apart.
  • a retaining bolt can be arranged on an edge area for attachment to the handling device. This eccentric arrangement of the retaining bolt ensures that the area of the spectacle lens retaining shaft remains completely free of elements of the handling device.
  • an advantageous guidance of the vacuum connection is also connected, which is in the form of bores from the depression through the plate-shaped enlargement of the base and can guide the retaining bolt.
  • a spectacle lens edge processing machine Of a spectacle lens edge processing machine, only one housing area 1 is shown in section, which shows a machining space 2 for a raw lens and the halves 3, 7 of a spectacle lens holding shaft.
  • the axially immovable, rotatable part 3 is referred to as a centering shaft and carries at its free end a clamping sleeve 4 which can be subjected to a vacuum via an axial bore 5 in the centering shaft 3.
  • a vacuum connection 6 is provided on the housing 1 in the area of the bearing of the centering shaft 3.
  • Coaxial to the centering shaft 3 is the second half 7 of the spectacle lens holding shaft, which is referred to as the clamping shaft and is axially displaceable.
  • a ball adapter 8 with a soft support tension ring is arranged at the free end of this tension shaft 7.
  • a raw glass 24 can be removed from a container (not shown) and moved between the area between the centering shaft 3 and the axially retracted clamping shaft 7 by means of a handling device 9, on which a holding device 10 is arranged.
  • the surface of the raw glass 24 facing the clamping sleeve 4 has its axis exactly coaxial with the axis of the centering shaft 3 when the raw glass 24 is attached to the clamping sleeve 4, irrespective of the angular position of the surface of the raw glass 24 by the receiving device 10 is held, occupies.
  • a block or suction device 25 is attached by means of a conventional centering device to the optical surface of the raw glass 24 opposite the receiving device 10, and its axis also runs coaxially with the axis of the centering shaft 3 when the handling device 9 attaches the raw glass to the clamping sleeve 4.
  • the block or suction device 25 can also be held in the clamping sleeve 4 by negative pressure if it is sealed in a suitable manner with respect to the clamping sleeve 4, since a secure mounting on the centering shaft 3 is already ensured in this way if the receiving device 10 is released by releasing the negative pressure and before the ball adapter 8 is pressed against the raw glass 24 by axial movement of the tensioning shaft 7.
  • the holding device 10 is shown in FIG. 2 on an enlarged scale and consists of a base 11 with a recess 12.
  • the base 11 has an annular surface 13 which is shaped in a complementary manner to an outer spherical cap surface 19 of a spherical cap 17.
  • the base 11 has a plate-shaped widening 23, on the one edge area of which a retaining bolt 15 is fastened.
  • the handling device 9 engages on this holding bolt 15.
  • a radial bore 14 leads from the depression 12 to an axial bore 16 in the retaining bolt 15. Via these bores 14, 16, the depression 12 can be subjected to a controlled vacuum.
  • a spherical cap 17 is inserted into the depression 12, the spherical cap surface 19 sealingly abutting the annular surface 13.
  • the spherical cap 17 is held on the base 11 by means of a mushroom-shaped holder 22 which is guided through an opening 18 in the spherical cap 17.
  • An edge 20 of the spherical cap 17 is provided with an annular, soft lip seal 21.
  • the raw glass 24 provided with a block or suction device 25 in a conventional centering device is, for example, arranged horizontally in a container from which it is to be removed by means of the receiving device 10.
  • the block or sucker 25 is inserted into a holder in the container, which determines the position of the block or sucker 25 and the optical surface of the raw glass 24 to which the block or sucker 25 is attached.
  • the optical surface of the raw glass 24 opposite the block or sucker 25, to which the receiving device 10 is to be attached can have a different angular position, which may be due to the fact that the raw glass 24 is provided with a prismatic or cylindrical cut.
  • the spherical cap 17 adapts to the angular position of this optical surface, while the relevant position of the block or sucker 25 or the optical surface against which this block or sucker 25 rests remains unchanged.
  • the spherical cap 17, which is sealed by means of the lip seal 21 is sucked firmly onto the raw glass 24 and is drawn into the depression 12, so that the friction between the annular surface 13 and the Spherical cap surface 19 prevents any displacement.
  • the raw glass 24 can now, as already described with reference to FIG. 1, be attached to the clamping sleeve 4 of the centering shaft 3 and is also securely held there by the application of negative pressure. After the negative pressure on the receiving device 10 has been released, it can be moved out of the area of the centering shaft 3 and the axially displaceable clamping shaft 7, after which the ball adapter 8 with the supporting clamping ring is moved against the raw glass 24.
  • the ball adapter 8 adapts exactly like the spherical cap 17 to the angular position of the optical surface of the raw glass 24 against which this ball adapter 8 is pressed, so that even when the raw glass 24 is clamped between the centering shaft 3 and the tensioning shaft 7, no change in the angular position of the optical surface of the raw glass 24, which faces the clamping sleeve 24, occurs.
  • the raw glass 24 can also be attached to the clamping sleeve 4 without first attaching a block or suction cup 25, if this is provided with an annular seal, as has already been described with reference to the spherical cap 17. In this case, too, the angular position of the surface of the raw glass 24 lying against the clamping sleeve 4 is clearly determined.
