Definitions
- the invention is concerned with the improvement of a proven, proven and proven manufacturing method for grinding and / or polishing gemstones over many centuries.
- This method is concerned with attaching a next follower pin as a handling or processing pin to the stone to be ground, which is previously held by a preceding pin which served, for example, as a measuring pin preceding measurements on the stone to the geometry of the rough stone to be ground, in particular Raw gemstone to fit best possible in a winning form of a polished gem, respectively the other way round.
- the gemstone in its desired geometric shape is to be exploited in the best possible way, reducing the loss of raw volume (in particular, to make it volume-optimized).
- Attaching the first wooden pencil is dependent on his own perception and experience.
- the ratio of the two pins to be attached has no defined, repeatable accuracy, or only that accuracy that can add the experienced grinder of the first pin attachment and the second pin attachment.
- the object of the invention is to simplify and automate the repositioning from a first pen to a follower pin, thereby achieving the accuracy necessary for automated processing in measuring and / or grinding and / or polishing, to provide coordinate systems for the orientation and the geometric placement of either raw, semi-finished or finished stone to be retained and transferred during the Umrochen (in a calculating or controlling process computer).
- the invention proposes the claims 1 and / or 15 before.
- the pins for measuring and processing the stones are the subject of claims 20 and 25.
- the Umstatten relates to a change from a measuring pin to a first follower pin as a processing or handling pin on the one hand (claim 7).
- the Umstatten within the meaning of this problem also relates to the change from a first handling or processing pin towards a second handling or processing pin (claim 8) to edit the other hemisphere (the profile of the still crude stone opposite to the circular plane) can, in particular, grind and / or polish.
- the procedure for attaching the next processing pin, "follower pin”, begins with the assembly or “fixing” of this pin to either the rough one or at least half finished and polished stone. Attachment is via a second splice which is spaced from the first splice to which the old stylus is still attached as the previous stylus.
- the second splice is disposed on a surface portion of the stone defined in alignment with the axis of the first preceding pin, but this geometric relationship is not mandatory. Placing the new pen at an angle greater than or less than zero. the still holding pin, the position of the stone to be machined relative to the new pin (first processing pin) can be specified.
- Machining pin is given the preference of axial alignment.
- the next pin as a follower pin is the first handling or processing pin on a previous pin as the measuring pin. If the other hemisphere of the stone to be processed, a first handling and processing pin is replaced with a second handling or processing pin, both of which may be geometrically identical, but opposite (coaxially) are arranged, so surface-spaced, temporarily both, and for the machining process only the later arranged pin, which sticks or adheres to the stone, in contrast, the previously arranged handling and processing pin is separated from this stone.
- the stone is first held on the previous pin. Also during the initiation of the exchange process (repacking) the stone becomes at this previous one
- Pen held (first feature of claim 1).
- the follower pin in the aforementioned sense, is placed at a distance from the location where the previous pin is glued to the stone, and vice versa.
- the follower pin receives a viscoplastic adhesive on the front end, in particular one or a kind of resin, which is able to cure.
- the follower pin is attached with this adhesive - in one of plant
- the on-move-to-move can also be inverse, so that relatively of a
- Reduction of the spatial distance of stone and coated front end of the follower pin is to be spoken (second feature). If both pins are placed on the stone, the new contact point is cured as a second bond. For example, by thermal influence or by the influence of light from a UV source (claim 8), which is positioned with its beam on the splice.
- the stone with two pins is now held by another holding device, such as a tensioning jaw device or a chuck, so that the old pin protrudes freely.
- the positioning of this old pin as a previous pin under a heat-supplying source provides by thermal conduction for a supply of thermal energy to the first splice (fourth feature of claim 1).
- the introduction of the heat is preferably carried out by a hot air blower and a hot air bundling nozzle to act on the previous pin and introduced via this pin in the first splice by heat conduction.
- Another distance is provided as a distance, with the meaning that the predetermined by hot air thermal energy is not directly on the first bond
- the release is done by applying a force component, for example.
- a transverse force which acts outside the axial direction of the two pins, preferably perpendicular thereto.
- This force component acts on the previous pin as the pin to be severed (last feature of claim 1).
- the release force With the release force, the weakened adhesive is physically released (claim 15), and the pin is separated from the stone, in particular in the form of a simple fall in a vertically acting from above force.
- Other directions of the release force are from obliquely upwards or backwards along the axis as a pulling force.
- the follower pin previously connected to the stone at the second bond, continues to support the stone, and after this follower pin is clamped to a handling arm, preferably in a jaw fixture, the stone has no relative movement to one or more of the release operation learn another pen (claim 14).
- the measurement is optimized and the order of processing of the hemispheres is determined. There is a certain dependence or not directly foreseeable influence.
- the measuring pin has a very thin mounting or mounting shank, with which it is to be attached by a first gluing on the raw stone.
- a position is under two criteria selected, which is favorable for the attachment, in order subsequently to have the largest possible optical space for optical measurement. This would be to choose a location on the stone, which is uninteresting in the measurement (since a blind spot arises here), and has a certain flatness, in order to be low on the thin attachment pin and easy to compensate programmatically.
- the measuring pin After the measuring pin has completed its task, the rough stone has been measured and a machining pin is to be adhered to a spaced location of the first splice, it is determined how the first grinding process is going on.
- the machining pin is not necessarily arranged axially aligned with the measuring pin, but mainly as it requires the following processing, and allows the handling system in the positioning of the machining pin,
- Claim 34 it is determined whether the processing controlled by the program system (initially primarily the grinding of the tip end or the flat end of the design mold) takes place.
- the controlling program system can switch over and compensate, claim 36.
- the supply of the first processing pin by a handling system is hereby adjustable only at a certain angle, at least less than spatially 180 °, so that there is only a limited direction specification for tool reasons.
- the attachment of the first processing pin will be such that the first processing is on the flat side of the molded gemstone (the panel side) or from the pointed side of the molded gemstone (from the gazebo side) formed gemstone in the raw stone is fixed only after the measurement, and before this measurement, the measuring pin was arranged so that these two assignments to each other are not always optimized, and often are dependent on user experience.
- This visibility can be compensated by switching the program system for the grinding process by this Programmystenn, claim 36, whether the grinding starts from the panel side or the pavilion side, just from this side, which is possible due to the spatial conditions and due to the setting angle of the handling member which feeds the first processing pin. If the attachment of the first attachment pin is not possible at the location provided by the program system for the first processing from the panel side, the program system switches in the above sense and relative to the placement of the first processing pin location of the splice and direction of the first processing pin to the raw stone in the other hemisphere, in order to start grinding from the pavilion side, claim 35, 36.
- the first gluing point should therefore be as flat as possible, because it has to be calculated out after the optical detection of the program technology, as a blind spot, which is to be replaced by the simplest possible surface contour.
- the follower pin ie the first processing pin, should be arranged perpendicular to the (optimized) round-top plane. This placement in place and direction is already a consequence of the calculation and the position of the shaped stone in the raw stone.
- the adhesive is aligned in exact axial alignment with the direction of the stone still glued on the first processing pin, also calculated by the program system.
- a release and a subsequent separation of the "previous pin" by a free-standing edge or a web is exercised (claim 10).
- the edge against the isolated (previous) pin to be moved, or vice versa which movement is preferred (claim 11).
- the edge is also preferably located near the heat source, so that no long distances for the movement of the holding device as a handling arm are necessary; particularly preferably, the edge is arranged above the outlet of the hot air (claim 13).
- the stone is thereby moved as a combination of stone and two pins arranged thereon (claim 1 1), up to the time at which one of the two pins is released and separated at the edge or the web. A relative movement of the stone to both pins does not take place after the attachment of the new pin until loosening or severing the old pin (claim 14). This period secures the
- Preferred materials for the pins for measuring or processing or handling are all types of metals and metal alloys, particularly preferred measurement (claim 12).
- Hot air device (claim 13, claim 16) a time of not more than 40 seconds, preferably less than 20 seconds are required for the measuring pin to bring sufficient thermal energy in a pin for releasing the splice (claim 4, 38).
- the Temperature is about 80 0 C to 10O 0 C, whereby the stone (gemstone) is not excessively thermally stressed, but at the same time not even the forces required during shearing are too large (claim 1 1, claim 14, claim 17).
- the introduced heat energy spreads through thermal conduction in the pen up to the
- Adhesive point which can be so precisely thermally soaked (claim 2). It is understood that while the thermal energy practically exclusively in the longitudinal direction of the pin (which is to be separated) out (claim 3).
- the first pin to be cut off is first the measuring pin, that is, the one which served to measure the stone and its associated one
- the measuring pin is no longer required.
- the remaining adhesive test of the first stop which remains after disconnecting the measuring pin, is removed during grinding.
- the measuring pin has a front as small as possible, with little area or cross-section, to cover as little as possible of the stone, it must first be measured (claim 9,15).
- a larger area at the front end makes sense in order to be able to apply greater forces for grinding and / or polishing, so that the handling or processing pin has an area of greater than 4 mm 2 at its front end should (claim 9,20).
- the measuring pin should preferably be smaller than 3 mm 2 at its front, and preferably larger than the factor 2, the surfaces of the front ends of the two different pins should be different (claim 9,25,20,30).
- the dependent claims of claim 20 to claim 29 relate as respective embodiments also on the set (claim 30).
- the different tasks for the at least two pins used to hold the stone rewrite their geometry, where they are not completely different, but not more than half.
- the measuring pin for measuring (claim 25) is used to hold the stone in order to measure it in a measuring station so that a coordinate system is set, that this stone carries for further processing and it is assigned from the computer and remains.
- the handling pin in particular also for processing in the sense of grinding or polishing, adopts the measured stone for said further handling, in particular the processing.
- the handling or processing pin is particularly formed at a front end (claim 20).
- Another handling or processing pin designed to process the opposite hemisphere of the stone may look the same.
- the measuring pin and the machining pin have a same rear portion, so that both pins can be operated by the same handling systems, can be taken and dropped.
- the purpose of the intermediate section which has a gripping zone for both pins, which can be grasped with a handling system, in particular a gripper arm with front parallel movable jaws, and clamped between the jaws. Above the gripping zone, the pins are different, below the gripping zone, the pins can be the same design.
- gripping zone a circumferentially symmetrical gripping zone is provided. It extends over the entire circumference of an approximately assumed intermediate portion, so that the pin can have any circumferential position in a tray, from which he wants to remove a handling arm. Particularly preferred is a circumferential groove-shaped notch (claim 21). This allows the jaws of the
- Handling arm have projections with which they can engage in the notch in any rotational position of the pin.
- an identification tag which allows to detect the rotational position of the pin reproducible or detect with measuring systems.
- this marking is a radially extending web, also called a radial web (claim 22).
- the marking is aligned from the gripping zone to the front (or front end), which training is preferred, so that the measuring pin and the machining pin are also the same extent formed.
- the respective holding portion which is the front-side portion.
- the respective shaft portion is preferably formed the same, which is arranged on the opposite side of the gripping zone.
- the holding portion in the machining pin is at least partially conical, which taper extends to frontendig.
- the taper serves to reduce the diameter of the gripping portion (gripping zone) towards the front end, which is attached to the stone via the adhesive.
- At least 4 mm 2 is the mounting surface of the machining pin, preferably larger.
- the adhesive is applied to this surface and then adhesively attached to the stone and cured.
- the intermediate section is particularly pronounced as a gripping zone. It has a diameter that is larger than all other sections. As a result, transversely to the axial direction, the extent of the shaft portion and the holding portion is smaller than the
- the holding end is also at least partially conically formed on the front side to the larger of the transverse dimension
- a set of at least one pair of measuring pin and machining pin is used (claim 30).
- the training of measuring pin and machining pin can be as explained and claimed above.
- a plurality of stones are arranged on a plurality of measuring pins in order to be stored or "stored” with their shank portions in a register until they are gripped by the handling arm respectively at the gripping zone and an optical measurement (in short: measurement) are supplied or after a measurement the Umringvorgang (claim 1, claim 15) are supplied.

- Figures 3a, 3b show two representatives of different pens.
- the pin 20 is a first handling or machining pin
- the pin 10 is a first measuring pin.
- pin 30 Another form of handling or machining pin is pin 30, which is more apparent in Figures 7, 8 and 3c.
- the measuring pin 10 has a first shaft 12 and a much thinner attachment or mounting shaft 14, with which it is attached to the stone 3 by a splice, see. for example, the figures 4a, 4b.

- a circumferential groove-shaped score line 13 a is provided, which corresponds in shape and cross section of a corresponding score line 23 a of the handling pin 20. Both pens must be handled and the handling
- Devices can pick up the measuring pin and the machining pin 20, move it and put it back in a suitable place. For this purpose, they attack at the gripping zone with a correspondingly shaped projection.
- the gripping zone has a larger diameter than the other portions of the pins
- the first processing pin 20 has a relative to the holding portion 14 of Figure 3b significantly longer front portion 24, which tapers in the course of its course, towards a front surface portion 24f, on which symbolically an adhesive 21 for forming a bond to the stone 3 is shown. Also, this pin 20 has a tab portion 25 in a one-piece transition from the described longer
- Section 24 to the handle portion 23 in which the circumferential notch 23 a is mounted for example, as a V-shaped or U-shaped groove which extends circumferentially symmetrical.
- a shaft 22 is provided which has the same configuration as the shaft 12 of the measuring pin of Figure 3b.
- Both pins are formed substantially the same in the lower region, in particular the measuring lugs 25,15 are harmonized (at least in the circumferential direction the same width), so that based on these flags, the relative position of the pin can be determined in order to the relative position of it through arranged the splice
- Steins 3 close. They serve the marking or the corresponding recognizability of the position, so that they are functionally called 'marking sections'.
- processing pin 30 The other alternative of a handling or processing pin, referred to below as the processing pin 30, show the figures 3c, 3d, 7 and 8.
- Section 32 is again comparable. Again, the holding zone 33 a is provided as a circumferential notch placed in the handle portion 33. The lower shaft portion 32 is not visible in Figure 7, since it is inserted into the receptacle of the retaining plate 40.
- the front section 34 consists of a base and two essentially conical sections 34 a, 34 b, which are in opposite directions, so that a tapered zone 34 c results in the intermediate region of the section 34.
- the front portion 34 can serve two purposes, it can taper from the handle portion 33 and at the same time have a front 34f having a large area to be well retained and strong forces received on the stone 3 with a clear splice ,

- the different stones can be clearly seen again in the rough stone register of FIGS. 6, 6a. Their coating for neutralizing the surface takes place according to FIG. 5.
- an application device 8 is used to apply a powder to the surface of the raw stone 5, which surface is unified and opaque, preferably a white coating. This allows a simplified measurement and a more accurate optical measurement.
- the coating has a maximum thickness of 1/100 mm (in the sense of 10 microns), but is not critical and should not be too strong to improve the measurement.
- the thus coated rough stones are shown arranged in the register of Figures 6, 6a on measuring pins 10, in each case at its grip zone 13 in the circumferential notch 13a of a handling device and can be transported in the system of processing and transportable.
- Figure 13 shows the overview of the program system PS, which controls the system.
- the measuring station M misses the stone.
- the movable gripping device 50 moves the stone with the metering pin or the stone with handling or processing pin 30 (or 20) from and / or to a respective location.
- the respective or several stone (s) can be temporarily stored in the raw stone register as, for example, support strip T.
- a jig 79 holds the stone in the process of being past the nozzle 61, 61a and the UV curing device 80.
- a handling arm 70 holds and moves the stone on the handling or processing pin to the grinding S and polishing P.
- An input system E via keyboard and screen lets the user intervene and the PS controls the system.
- Figure 13 shown Calgary ramm controlled system PS.
- the manner of the control is described in detail here, and the person skilled in the art can realize it according to this description with common programmable devices and elements.
- This handling description is based on the figures 8 ff, where it is assumed here that the handling and processing pin 30 is used, which has a larger front surface 34f, which in particular is roughened geometrically, for example by concentric rings.
- On the front surface 34f is an adhesive 31, which is first applied via an applicator 60 in liquid form.
- the applicator 60 is provided with an adhesive reservoir 63 is moved to the front surface 34f, or a handling device 70 with concentric jaws 76, on which the processing pin 30 is clamped, is moved to the fixed adhesive device 60.
- a tapered nozzle 61 with a front end 61 a brings a drop of adhesive, in particular in the form of a curable resin, on the surface 34 f, which can be followed with reference to FIG 8.
- the machining pin 30 thus provided with an adhesive point 31 is moved further on the handling arm 70 according to FIG. He is thereby moved to a clamped already in another handling arm 78 stone 3, which is still attached to the measuring pin 10 with a splice 1 1.
- This measuring pin 10 is seated in a further chuck 79 (jaws provided with chuck) and waits in the working area of a UV curing device 80.
- the movement of the handling arm 70 to the right in FIG. 9 leads to the point where the adhesive point 31 bears against the vertically oriented front surface of the stone 3 with a still curable (vispoplastic) adhesive. In this case, the distance between these two objects is reduced, which preferably takes place by movement of the handling arm 70.
- the adhesive 31 adheres to the machining pin 30 and to the front surface of the stone 3 at the new splice 31 '.
- a brief activation of a few seconds for the action of a UV light beam on the splice 31 ' ensures their curing, for example by polymerization.
- two light guides 81, 82 are provided, which are held by an upper arm and a lower arm 81 a, 82 a on a vertical support 83 to allow the exiting, free light beam from both sides of the adhesive 31 to act.
- the arms are displaceable together with a vertical support 83.
- the light guides can thus be aligned with the splice 31 'at least with their ends from which the UV steel emerges.
- a circumferential rotation of the measuring lugs 15,35 relative to each other, as shown in Figure 10, is also possible. You do not need to be aligned axially.
- the program system calculates this when the coordinates are transferred with the change of the pins.
- the axes 100,101 of the pins 10,30 are at an angle greater or smaller than 0 ° to each other. This is achieved with an adjustment of the handling arm 70 in the x-y plane, and a rotation of the stone 3 about the axis 101 with the tensioning device 79.
- FIG. 9b The various orientations of the axes 100, 101 are shown in FIG. 9b, wherein it is assumed that an axis 102 lies in the axis 101, which axis 102 is the axis perpendicular to the intended plane of the ground stone.
- Figure 9a illustrates the approach of the arm 70, which is pivotable in the xy plane and is movable along path b without up / down inclining capability. Also in the higher direction z, the arm 70 is adjustable. For attachment of pin 30 in the xy plane, the stone is rotated by the other jig 70 so that the perpendicular 102 comes to rest on the board plane of the stone in the xy plane. The program system converts the coordinates or systems accordingly. An adjustable degree of freedom on the arm 70 can thus be eliminated, which favors the accuracy and lowers the cost of this handling tool.
- the new pin 30 is now attached.
- the tensioning device 79 releases, so that the
- Measuring pin 10 is released and now a freely projecting pin 10 with its lower shaft 12 is.
- the handling arm 70 holds with the second pin the combination as shown in FIG. It moves this combination according to FIG 11 to a hot air device 90 shown there, which acts on a nozzle 91 with air outlet 91 a hot air flow on the portion 12 of the measuring pin 10.
- the measuring pin 10 can initiate.
- the combination of two pins and a stone is moved backwards to be loaded at a tee edge 94 as a web or edge, on an associated longer web formed, with a transverse force, which is symbolized by F q .
- the resulting structure is a handling arm 70 with a jaw device 76 which carries the measured stone 3. That's it
- Coordinate system has been transmitted without loss of accuracy and the controller knows exactly in which rotational position and in which axial position of the stone 3 with its geometric extension is located at a certain position of the handling arm 70.
- the controller has moved this handling arm to a grinding wheel 200, which is moved at the angular velocity ⁇ (omega).
- ⁇ angular velocity
- FIG. 12c the polishing on a polishing disk 300 is shown.
- the arm 70 on the chuck 76 holds and guides the stone 3 with the ground facet on the polishing pad.
- the relative rotational position and feed position can be measured by the marking 35.
- processing pin 30 is replaced with another
- Machining pin which is attached to the stone on the already processed side.
- the attachment is carried out as previously described for the pin 30, wherein the follower pin may have a different geometry on its front front, for example, a small depression, but need not have.
- the axes of the pins are congruent here.
- the severance of the last machining pin can also be effected.
- a thermal influence is preferably used, but none with higher
