Definitions

  • the present invention relates to a method for thermal blocking or defrosting of the Alloys and a block piece set with alloy on a workpiece for the lens manufacturing, as well as a system for performing of the procedure.
  • a protective film and / or a protective lacquer may be provided on which then the alloy glued or melted with block piece.
  • the present invention is based on the object Method and an installation for carrying out the method to create, with which the o. g. Disadvantages eliminated and with which on easy and inexpensive Way blocking or defrosting and peeling off a Block Federationes and the Alloys on the surface of a Workpiece, in particular working spectacle lens or machining blank is made possible. It should be a Manufacturing process can be optimized. He should be full be automated, reduce costs and damage on the surfaces of the spectacle lens or of the workpiece avoid.
  • the present invention has proven to be special proved advantageous in a system directly or via corresponding, separate holding devices preferably pairs of right and left lenses as workpieces Insert, for example, on its concave side in one Machining center were processed.
  • the workpiece or the machined Eyeglass blank in a tempered water bath supply.
  • a corresponding transport device takes the corresponding workpieces with by means of Alloy fixed block piece and leads this a first Container too.
  • the first container is filled with liquid and is tempered by at least one heater. The temperature of the liquid corresponds at least to Melting temperature of the alloy or the adhesive or the Metal alloy.
  • the conveyor is over corresponding deflection rollers, deflection elements od.
  • the conveyor By guided the container such that the workpiece with fixed block piece over a first oblique area obliquely down against a bottom of the container being introduced in these, being in this first bevel area the alloy, as well as the block piece to be preheated, and following the bevel area the conveyor, in particular the workpiece in one horizontal area led upside down through the container will, so in this position and position continuously the alloy melts or defrosts and then the Block piece releases from the workpiece and at least one Transport device falls. From there will be the block piece out of the plant.
  • the alloy drips through the Liquid to the bottom of the container, as a slope is formed, and can there via a preferably tempered outlet can be removed for reuse.
  • At least one brush element is arranged, preferably perpendicular in the region of a side wall, in order while passing the workpiece its surface from residues of alloy or impurities.
  • the Alloy and block piece freed workpiece in one second container introduced by the conveyor in which a plurality of spray nozzles are arranged.
  • a plurality of spray nozzles are arranged.
  • From the spray nozzles is preferably tempered water, added with detergent on the surface of the Workpiece sprayed to the film and / or a Dissolve protective coating or peel off. Usually they are Slides in certain liquids and Cleaning liquids formed resolvable.
  • the working blank of the lens becomes the workpiece in another container by means of the conveyor introduced, in which provided at least one spray nozzle is, over which liquid preferably clear water to Post-cleaning the workpiece, especially its Surfaces applied. From there, over the Transport device moves the workpiece back to the insertion point guided, and can there manually or automatically by means of an insertion or removal device for further Processing be removed.
  • a workpiece 1 for example a blank or a processed blank or a processed spectacle lens. So that the spectacle lens or the blank are processed can, is on a surface 2 a block piece 3 means Alloy 4 set, in particular glued.
  • a protective varnish 5 and / or a film 6 be glued to the surface 2 of the workpiece 1.
  • the Block piece 3 is used for clamping and picking up the Workpiece 1 in a production machine eg. For Polishing, milling or machining the concave opposite surface 7. After editing and Completing the workpiece 1 to the lens must that Block piece 3 again from the workpiece 1, in particular of its surface 2 or protective coating 5 and / or film 6 be removed.
  • the Alloy 4 is preferably a low melting metallic alloy or a low melting adhesive, which is tempered by, for example, in the warm water bath melted.
  • the workpiece 1 with Alloy 4 and block piece 3 in a holding device 8 personallylösbar means retaining pin. 9 clamped, wherein the workpiece 1 and in particular its Surface 2 on a plurality of bars 10th rests.
  • the holding device 8 may comprise one or more workpieces 1, Depending on the embodiment, it can also be re-releasably clamped or take up. Especially in the peripheral areas is about the possibly spring-loaded retaining pin 9, the workpiece. 1 clamped.
  • the holding device 8 can be redetachable or integral part of a conveyor 11, as in Figure 2 is shown to be. In Figure 2 is a system R shown in which of a dock 12, the Workpiece 1 with Alloy 4 and block piece 3 directly or if necessary by means of the holding device 8 in the conveyor 11th is inserted.
  • the workpiece 1 is fixed there Block piece 3 and Alloy 4 in a first container thirteenth transported, wherein the conveyor 11 via corresponding deflection rollers 14 actively driven or passive running running, led into the first container 13 becomes.
  • the introduction of the workpiece 1 takes place with Alloy 4 in the container 13 via a sloping portion 15 in which the Alloy 4 is preheated for defrosting.
  • the Conveyor 11 in a horizontal region 16th deflected so that the workpiece 1 down against a Bottom 17 of the container 13 is aligned.
  • the workpiece 1 is overhead, the means down against the bottom 17 of the container thirteenth aligned by the heated liquid in the container 13th guided.
  • Corresponding heating devices 28 can directly or indirectly the container 13 or its contained therein Heat the liquid to the melting temperature of the Alloy 4.
  • An advantage of the present invention is that a Blocking or defrosting or melting of Alloys 4 via Head takes place, so that then in the area overhead metallic block piece from the workpiece 1 down to a Transport device 18.1 falls. This will be the Surface 2 in no way by the dissolving Block piece 3 damaged by melting of alloy 4, but falls in the horizontal area 16 directly on the Transport device 18.1 and is about this one passed further transport device 18.2, which the Block pieces 3 brought out of the system R or transported.
  • the liquid Alloy 4 drips through the transport device 18.1, 18.2 and falls to the floor 17 of the Container 13. Since the bottom 17 formed as a slope 19 is the liquid Alloy 4 in the container to one flies heated outlet 20 and can be removed there or one further processing or reuse become.
  • the first container 13 is on a side wall 21 or in its area, following the detachment of the Block piece 3 from the workpiece 1 at least one brush element 22 provided on which the workpiece 1 by means of Conveyor 11 is guided along, wherein the outer Surface 2 of the workpiece 1 by means of the brush element 22 of impurities or of remaining Alloy 4 in the liquid of the container 13 is released.
  • a second Container 23 is provided, through which then below, the Conveyor 11 also via corresponding Deflection pulleys 14 is guided.
  • the protective varnish 5 and / or the film 6 of the Surface 2 of the workpiece 1 by spraying with Liquid and detergent removed, dissolved or possibly replaced.
  • the container itself can have its own Heating device 28, wherein in a lower area Cleaning liquid is provided if necessary, which also a Rinsing and swiveling of protective varnish 5 and / or film 6 from the surface 2 of the workpiece 1 is used.
  • the liquid and cleaning fluid can then in a filter 26 are cleaned before they Processing device 25 is supplied again. At This place can also be thought of the liquid completely divert the second container 23 and to to dispose.
  • a third container 27 can be arranged in the system R, through which the conveyor 11 is also guided.
  • further spray nozzles 24 may be provided, which spray only cleaning liquid, in particular water for rinsing and cleaning the workpiece 1 or.
  • the conveyor 11 is then guided via corresponding guide rollers 14 to the insertion point 12 and closes the circuit there.
  • the machined workpiece 1 can be removed manually and / or automatically.
  • corresponding automated insertion or removal devices 29 may be provided to insert the workpieces 1 in the conveyor 11 or to remove from there again after processing or insert the holding device 8 in the conveyor 11 or this with inserted workpieces 1 again after processing refer to.
