Description

The The invention relates to a device for processing glass components according to the generic term of claim 1.

in the Within the scope of the present disclosure, the term "processing" is thus to be understood understand that "processing" means "separating", "reshaping" or "joining" (for example Melting of parts or heating and heating of areas) of glass includes.

the Persons skilled in the art are familiar with methods for fusing glass raw parts.

at the known method must basically rotate the glass blank during joining, thus by the resulting centrifugal forces collapse of the soft glass inside the melting process is prevented.

at The known methods are thus the glass raw parts to be joined in one Clamping machine clamped and connected with a fusion seam. The energy required for melting is usually with a Burner introduced.

at Small and medium-sized glass raw parts become the burner operated with natural gas and oxygen. For glass raw parts with large nominal widths the burner is operated with natural gas or oxygen and hydrogen. For medium-sized glass raw parts, the natural gas-oxygen mixture can also be combined with high frequency.

The known methods have the disadvantage that they only for Glasrohteile are suitable up to a certain maximum nominal diameter, because the Glass raw parts only rotated at a certain maximum speed can be and a uniform heating at big Nominal widths a rotation with a higher than this maximum Speed requires.

• – schlechte Energieausnutzung durch offene Flamme
• – hierdurch lange bis sehr lange Prozesszeit erforderlich
• – erhöhtes Bruchrisiko durch nicht exakt reproduzierbare Auf- und Abwärmphase
• – mittlere hohe Hitzebelastung für Mensch, Maschine und Umwelt
• – Gesundheitsbelastungen durch UV-/IR-Strahlungen
• – Qualitätseinbußen durch Bildung einer ”Wasserhaut” durch Kondensation, wodurch ein erhöhtes Bruchrisiko entsteht
• – Qualitätseinbußen in der Schmelznaht durch ungleichmäßige Wärmeeinbringung im Glas
• – hohe thermische Spannungen im Glas durch die Wärmeeinwirkung
• – Verschleiß an Maschine, Vorrichtungen und Brennern durch die hohe und lange Hitzebelastung und mechanische Belastung durch Strömungsgeschwindigkeit der Gase
• – Verunreinigungen in der Schmelznaht durch Metallabtrag aus Leitung und Brenner
• – Energieeintrag mittels Hochfrequenz-Verschmelzung auf Grund des schlechter werdenden Energienutzungsgrades bislang nur für kleine bis mittlere Wandstärken geeignet

The hitherto industrially used methods have the following disadvantages:

• - poor energy utilization by open flame
• - This requires a long to very long process time
• - Increased risk of breakage due to not exactly reproducible warm up and down phase
• - medium high heat load for man, machine and environment
• - Health impact from UV / IR radiation
• - Quality loss due to formation of a "water skin" due to condensation, which results in an increased risk of breakage
• - Quality loss in the weld due to uneven heat input in the glass
• - high thermal stresses in the glass due to the effect of heat
• - Wear on the machine, devices and burners due to the high and long heat load and mechanical stress due to the flow velocity of the gases
• - Impurities in the weld by metal removal from pipe and burner
• - Energy input by means of high-frequency fusion due to the deteriorating energy efficiency so far only suitable for small to medium wall thicknesses

in the The scope of pure research projects was borosilicate glass 3.3 and AR glass with nominal widths of up to 70 mm using a CO2 laser merged. In this case, the laser beam was used to merge Outside on the glass surface directed. The laser beam was stationarily aligned to a point. The glass part to be processed rotated correspondingly fast to the uniform heat input to reach in the glass.

at the fusion of glass raw materials with larger diameters (and thus also larger wall thicknesses) ranges the relatively slow peripheral speed of the rotating glass body (for example are glass raw parts with a nominal width of 1000 mm with maximum Speeds of about 20 revolutions / minute) no longer off to one at stationary laser beam the required uniform heat input in the vitreous body to reach.

Of the The invention is therefore based on the object, a device or a method for processing large diameter glass components and wall thicknesses specify.

The The object of the invention is a device or a method with the characteristics of the independent claims solved. Advantageous embodiments of the invention are specified in the dependent claims.

According to the invention Strahlungsleitvorrichtung set at a high speed in rotation, and the radiation energy led out laterally. This has the advantage that in the same areas of the glass component to be processed with a high frequency without big ones Breaks energy is introduced, ensuring uniform heating becomes.

According to a preferred embodiment, the Strahlungsleitvorrichtung is disposed within the glass component to be processed and the Strahlungeenergie is deflected to the outside. It would also be according to an alternative embodiment conceivable that the Strahlungsleitvorrichtung is disposed outside of the glass component to be processed, and the radiation energy is deflected inwards.

According to one preferred embodiment the radiation guide is mounted on one side. According to one alternative version According to the invention it is also conceivable to use the radiation guiding device store on both sides.

According to one execution The invention is radiant energy (for example, a laser beam) for Melting of glass components with larger glass wall thicknesses or Nominal diameters introduced laterally into the rotating glass components.

there can the guide tube of the radiation energy (the laser beam) with his integrated beam deflection device (for example with a mirror deflection system) rotate at a very high speed (for example with a speed of the order of magnitude of 1000 revolutions / minute) to the required heat input in the vitreous body to produce quickly and evenly.

The Glass components to be processed according to the invention or glass raw materials are in particular raw glass components, preferably of quartz glass or borosilicate glass, in particular preferably borosilicate glass 3.3 from DN15 to DN1000.

The Glass components to be processed according to the invention or glass raw materials typically have wall thicknesses in the range of about 2.2 mm to approx. 18 mm. It is clear that the invention to be processed Glass components or blanks usually larger wall thicknesses for larger diameters and lower wall thickness have smaller nominal sizes.

Also according to the invention Wall thickness outside of the preferred range possible.

According to the invention, glass components also with very big ones Nominal diameters, for example nominal diameters in the range of 150 to 1500 mm are processed. Depending on the capacity of the used Holding device can also glass components with larger nominal widths are processed.

The lower limit of the nominal diameter depends on the type of apparatus used for processing glass components from. For versions with a disposed within at least one glass component Lichtleitvorrichtung must be at least slightly larger than the nominal diameter the outside diameter be the light-guiding device.

The upper limit of the nominal diameter depends on the size of the case the apparatus used for the processing of glass components existing holding device and its clamping device for the processing glass components or Glasrohteile from.

According to one execution The invention comprises a device for processing glass components a holding device for holding at least one to be processed Glass component, a Strahlungsleitvorrichtung for conducting radiant energy in at least a portion of the glass component to be processed, a storage device in which the Strahlungsleitvorrichtung about an axis is rotatably supported, and a drive means for rotating the Strahlungsleitvorrichtung about an axis at a speed (n3).

According to the invention, the Strahlungsleitvorrichtung be arranged and designed such that the radiant energy to the glass component of a region within the glass component is passed.

at the processing of a glass component, this example be stored on one side and the Strahlungsleitvorrichtung on an opposite Page. When processing two glass components, these can for example, on opposite Be stored on the sides and the radiation guide can on one of the two sides or preferably concentric on both sides to be stored.

According to the invention, the Holding device a clamping device for clamping the processed Glass component and a drive device for rotating the glass component around an axis at a speed (n1).

According to the invention, the Holding device a further clamping device for clamping a another glass component to be processed and a drive device for rotating the further glass component about an axis with a Have speed (n2).

According to the invention, the Device comprise a synchronous machine.

According to the invention, the Strahlungsleitvorrichtung a guide tube for conducting the radiation energy (a laser beam), which (the) coupled into the guide tube becomes.

According to the invention, the radiation guiding device can have a beam deflecting device, preferably with a mirror, which is designed in such a way that the radiation energy is substantially directed perpendicular to the axis of rotation of the Strahlungsleitvorrichtung from the Strahlungsleitvorrichtung in the direction of or to be processed glass components. In this case, the radiation guiding device can have an adjusting device for adjusting the beam deflection device.

The Adjustment device can be designed and constructed in such a way on the one hand, they have a fixed position of the beam deflection device pretend. Alternatively or additionally, the adjusting device also have a drive to the beam deflecting in to move, for example, wider areas the glass component (s) to be processed are energized, For example, to heat or waste heat wider areas. The Frequency of movement of the beam deflecting device should preferably be much smaller than the rotational speed n3, with the Strahlungsleitvorrichtung rotated, but may also be in the same order or larger.

According to the invention, the Beam deflection device be designed such that the angle, around the radiation energy through the Strahlungsumlenkeinrichtung is deflected, is adjustable and / or. In versions, in which the radiation deflecting device has a mirror, the mirror can be rotatable or adjustable about an axis. This has the advantage of having the radiant energy on the area the or the glass raw parts can be aligned, which processes should be. For wider areas can be a continuous adjustment take place to a recurring admission of subregions to achieve.

According to the invention, the Device an adjusting device for adjusting the Strahlungsleitvorrichtung along its axis of rotation (direction X) relative to the glass component (s) The adjusting device preferably has a control device has, which is designed and constructed such that a regular adjustment the Strahlungsleitvorrichtung between at least two positions takes place, the frequency of the adjustment preferably substantially is less than the rotational speed (n3) with which the Strahlungsleitvorrichtung rotates and preferably substantially larger than the rotational speed (n1, n2) is, with which the glass components) rotates.

through the adjustment, it can be achieved that the Strahlungsleitvorrichtung Energy in areas of certain width of the glass components) bring can, with each zone of the areas at regular intervals radiant energy obtained, for example, as a result of a reciprocating translational movement the Strahlungsleitvorrichtung along its axis of rotation (directions X). The frequency of the reciprocal translational motion is for constructional reasons preferably smaller than the rotational speed n3, with which the Strahlungsleitvorrichtung rotates. However, it is also conceivable that the frequency of the translational movement in the order of magnitude is the rotational speed n3 at which the Strahlungsleitvorrichtung rotates, or is larger. When large areas of the glass component (s) are energized be sure that the relative speed between the Radiation device and the glass component (s) (n3 + n1 or n2 or n3 - n1 or n2) not chosen in this way be that pattern of heated zones arise (for example, when the relative speed is exactly a multiple the frequency of the translational motion. The same considerations apply to designs, in which the beam deflecting device during processing of the glass component (s) is adjusted. The combination of an adjustment of the beam deflecting device and the provision of a relative movement between the Strahlungsleitvorrichtung and the glass component (s) is conceivable.

on the other hand could it also desired be intentionally applying energy only in a sloping zone, for example, at oblique edges between two glass components to be joined or at an oblique deformation range. In this case could Relative speed exactly to a multiple of the frequency of the translation movement be set or correspond exactly to it.

Instead of a relative translational movement between the Strahlungsleitvorrichtung and the glass component (s), it is also conceivable that the beam deflecting device the radiation guide is adjustable. For example, a Position of a mirror to be changeable such that the radiation direction can be varied within a certain range. The adjustment of the position of the mirror could then as above with respect to the relative position between the Strahlungsleitvorrichtung and the glass component (s), take place such that certain areas or oblique extending zones of the glass component (s) to be processed recurrently be energized.

1 shows a schematic representation of an apparatus for processing glass components according to an embodiment of the invention. The apparatus for processing glass components comprises a holding device 50 with two clamping devices 51 respectively. 52 for clamping the glass components to be processed. The clamping device 51 is rotatably mounted and is driven by a drive device 53 driven. The clamping device 52 is also rotatably mounted and is driven by a drive device 54 driven. At the in 1 As shown embodiment, the holding device is designed as a synchronous machine, such that the drive means 53 and 54 the clamping device 51 and 52 drive at the same speed.

The apparatus for processing glass components further comprises a radiation guide device 30 on, which is a first draft tube 31 having, in the holding device 50 is rotatably mounted. A drive device for driving the guide tube 31 is provided and may optionally in the drive device 53 be integrated.

The apparatus for processing glass components is illustrated with two glass components contained in the grips 51 respectively. 52 are clamped. In the clamping device 51 is a glass raw part 10 clamped and in the clamping device 52 is a glass raw part 20 clamped.

The drive device 53 is designed so that it the clamping device 51 and thus the glass raw part 10 can drive at a speed n1. Accordingly, the drive device 54 designed so that it the clamping device 52 and thus the glass raw part 20 can drive at the speed n2.

Preferably are the speeds n1 and n2 the same size, so a joining the Both glass raw parts in the area II can take place.

A detailed view of Area II, in which the two glass raw parts 10 and 20 to be put together is in 2 shown schematically.

The glass raw part 10 has a glass straw edge 11 on, with the glass raw edge 21 of the glass raw part 20 to be connected.

The glass raw part 10 has a wall thickness d1, and the glass blank 20 has a wall thickness d2. Preferably, the two wall thickness d1 and d2 are the same size, and it is also possible according to the invention for the two wall thicknesses to vary. The glass raw part 10 rotates at a speed n1, so that the resulting centrifugal forces prevent a collapse of the soft glass inwards during the melting process. The glass raw part 20 rotates in the same direction with the same speed n2 for the same reason.

The speeds n1 and n2 are the same and the rotation is in the same direction, so that the two Glasrohteile 10 and 20 can be joined together. The radiation guiding device 30 has a guide tube 31 in which a laser beam 40 to be led. The guide tube 31 has an opening 34 through which the laser beam can escape laterally from the guide tube. For deflecting the laser beam is a Strahlumlenkeinrichtung 33 provided, in the illustrated embodiment with a mirror. Behind the beam deflector 33 the guide tube has a short extension 32 on.

The radiation guiding device 30 is one-sided in the area of the clamping device 51 for the glass raw part 10 rotatably mounted and rotated at a speed of n3.

Preferably, the Strahlungsleitvorrichtung rotates 30 in a direction opposite to the direction of rotation of the glass raw parts 10 . 20 , so that a greater relative speed (= n1 + n3 instead of n1-n3) between the glass raw parts 10 . 20 and the Strahlungsleitvorrichtung 30 is reached. This has the advantage that the areas to be heated or to be fused are irradiated with radiant energy at a higher frequency, which is why a more uniform heating takes place. Alternatively, the glass raw parts and the Strahlungsleitvorrichtung could also rotate in the same direction, especially when the rotational speed n3, with which the radiation device rotates, is substantially greater than the rotational speed n1 and n2, with the glass blank 10 respectively. 20 rotates.

According to one only in 1 indicated embodiment, the guide tube 31 a long extension 35 have, in the region of the clamping device 52 for the glass raw part 20 is rotatably supported accordingly, so that the Strahlungsleitvorrichtung 30 is rotatably mounted on both sides. Optionally, in such an embodiment, the left or the right side or both sides of the radiation guiding device can be driven.

The generation of a laser beam and the coupling of a laser beam into a guide tube are known to the person skilled in the art. Since the lasers are relatively expensive with corresponding services, it will be before zugt to use a laser device for a plurality of devices according to the invention for processing glass components. According to the invention, however, a laser device for a device for processing glass components can also be used.

The maximum rotational speeds n1, n2 are, for example, in the range of approximately 20 rpm for glass billets with a nominal width of 1000 mm, while the guide tube 31 the radiation guide 30 is driven in operation at a speed n3 in the range of about 1000 U / min, to the heat input required for processing in the glass raw parts 10 . 20 to produce quickly and evenly.

The radiation guiding device 30 is also slidably mounted along the direction X, that a precise adjustment of the opening 34 emerging laser beam can be aligned with the processing area of the processed glass raw parts.

The Radiation device may according to another application also continuously a preferably oscillating horizontal movement along the X direction, if in a wide band-like area of a glass raw part or in band-like areas of two adjoining glass raw parts targeted a defined amount of energy to be introduced. The has opposite usual Procedures in which the energy, for example, with a burner is introduced, the advantage that the amount of heat input and the area in the heat is registered, can be controlled better, which makes a faster and more targeted heating and cooling of the area or the Areas can be reached. That's at the merger of two adjoining Glasrohteilen advantageous. Also is it is advantageous if a Glasrohteil molded after heating and subsequently cooled down again shall be.

Alternatively or additionally, the beam deflection device can also be designed to be rotatable about an axis of rotation in order to achieve an adjustment and / or adjustment of the target area of the radiation energy. 3 shows a schematic detail view of a beam deflection 133 to explain this alternative education or training of the above in connection with the 1 and 2 described beam deflecting device. Reference is made to the above embodiments and the differences are described below. The laser beam 141 hits the mirror and is deflected by about 90 degrees to the side (laser beam 142 ). The mirror is about a rotation axis 135 rotatably mounted. By setting a certain angle, a certain area of the glass raw material (s) to be processed can be exposed to radiant energy. In some embodiments of the invention, it is also conceivable to form the beam deflection device in such a way that the mirror is continuously adjusted with a specific frequency in a certain angular range, for example, to apply radiant energy to a wider area of the glass raw material or parts to be processed.

With the device according to the invention It is possible to process glass components, for example two To add glass raw materials by entering the laser energy in a relatively small edge area becomes.

It it is clear that the skilled person in studying the documents obvious Alternatives and equivalents solutions also fall within the scope of the present application.
