Definitions
- the invention relates to a device for supporting a glass sheet or a stack of glass sheets, said glass. More particularly, the device according to the invention comprises two supports successively supporting the glass, the second being able to take charge of the glass by unloading the first, or to unload the glass that it carries on the first.
- the invention is particularly useful for the handling of glass sheets, especially during their manufacturing process, especially during their cooling following their thermal bending.
- the device according to the invention supports and can convey the glass.
- a process for manufacturing glass sheets requires the sheets to be conveyed at different stations in which they are cut, heated, curved, cooled, etc.
- Various means for supporting and conveying exist as roll beds, gravity forming tools, quenching tracks, air cushions, suction top shapes (also called pick-ups), etc., each of these means having its advantages and disadvantages, depending on the case.
- the device according to the invention comprises two separate supports for supporting the glass one after the other.
- the glass is first supported by the first support, then the second vacuum support at this stage is positioned under the glass (following the displacement of one or the other of the supports or the two supports) then, following a relative vertical movement of the two supports making them cross (in side view), the second support supports the glass by unloading the first support, then the two supports move away one of the the other, the second support carrying the glass.
- the glass is first supported by the second support, then this second support carrying the glass is positioned above the first vacuum support at this stage (following the displacement of one or the other supports or two supports), then, following a relative vertical movement of the two supports making them cross (in side view), the first support supports the glass by unloading the second support, then the two supports 'move away from each other, the first support carrying the glass.
- the glass is thus transferred from one support to another and this is made possible thanks to a compatible geometry of the two supports between them so that these two supports do not touch each other when crossing at the time of transfer.
- the two supports are below the glass.
- this particular situation is called the transfer situation, regardless of the medium above the other and whether one is before or after the transfer.
- the transfer of the glass from one support to the other is made during a relative vertical movement of the two supports in transfer situation, during which the height level of the support surfaces of the two supports is reversed.
- the second support can be provided with an arm connected to its frame, the arm to hold it or to move it, for example by automatic mechanical means (such as a robot).
- the arm is attached to the frame or is a removable element that can be attached to the frame and detach. Viewed from above, the arm is an element external to the frame and the support surface of the second support.
- the arm is connected at one end to the portion of the frame directly supporting the glass support means and its other end away from this part of the frame and the support surface. When the two supports are in a transfer situation under the glass carried by one of the supports, this other end is visible as moving away from the glass / supports assembly.
- the arm has a substantially horizontal main direction.
- the device according to the invention is of particular interest during the cooling process of glass sheets following their thermal bending.
- the first support supporting the glass can be placed in a chamber at a particular temperature, then the second support takes charge of the glass to remove it from the chamber and drag it into a larger area. cold. The first support can then receive the next glass.
- the invention is particularly suitable for processes for treating glass sheets running one behind the other.
- the invention relates primarily to a device for supporting a glass sheet or a stack of glass sheets, said glass, said device comprising a first support and a second support, each of these supports comprising a frame and a support means glass connected to the frame, the support means of each support comprising a support surface of the glass, the two supports being able to be driven by a relative vertical transfer movement allowing the support surface of one to move to above or below the support surface of the other in order to carry out the transfer of the glass from one support to the other, the support means of the first support comprising a passage able to pass an arm connected to the second support during relative vertical movement.
- the expression relative vertical movement means that only one or the other of the supports moves vertically, or that the two supports move vertically, during this movement.
- the device is particularly adapted to support a glass sheet or a stack of glass sheets, in which case it is simply called "glass" in the present application.
- the lower face of the glass is supported in turn by the two supports, this face may be flat or curved.
- the invention relates more particularly to the field of the handling of hot glass, in particular between 400 and 600 ° C and curved, in the context of a manufacturing process of glazing of vehicles (automobile, truck, bus, agricultural vehicles).
- the support surface of a support can be continuous as is the case of a peripheral track.
- the support surface of a support can also be discontinuous.
- the support comprises a plurality of support elements each attached to the frame and each comprising a contact zone of the glass.
- the set of contact areas form the support surface.
- a support member may be connected to the frame at one end thereof and include the contact area at its other end. Generally the contact area is higher than the end by which the support member is attached to the frame.
- the fact that the support surface is discontinuous has the advantage that it can more easily adjust each contact zone independently of the others, so that this surface is at the right height and has the best orientation with respect to the glass to be supported.
- Each support element may also include an independent means of damping the reception of the glass.
- the air can circulate between the different contact zones.
- the means for supporting one of the supports may comprise a plurality of support elements fixed to the frame and each comprising a contact area of the glass, the set of contact areas of the support support elements forming a surface discontinuous support of the glass, specific to this support.
- the two supports can be of this type.
- the supports do not interfere with the relative vertical movement at the time of transfer of the glass from one support to another. It is therefore necessary that the geometry of these two supports is compatible to allow this movement. In this way, the two supports can pass through each other during the transfer. In side view, they cross each other.
- the support means of the first support comprises a passage allowing the arm of the second support to pass during the relative vertical movement. This passage is generally of a width in the range from 5 cm to 65 cm and more generally from 10 to 50 cm.
- the support means of a support must not be in the same place as the support means of the other support.
- the support surfaces of the two brackets must appear staggered so that the two brackets do not touch each other during the transfer.
- the support surfaces of the two supports appear separated, not overlapping, and can not be touched during the relative vertical movement.
- the second support may be such that its support surface (and its frame) is entirely circumscribed by the support surface of the first support in top view, when the supports are in a transfer situation.
- these support elements can be configured so that in top view
- the support elements of the first support are directed (from the frame) towards the inside of the frame of the first support,
- the support elements of the second support are directed (from the frame) towards the outside of the frame of the second support,
- the support elements of the two supports are offset from above during the relative vertical transfer movement.
- the support elements of the two supports can intersect in the manner of branches of two combs.
- This configuration makes it possible to support the two supports substantially the same area of the glass, that is to say substantially the same distance from its edge.
- two contact zones of support elements adjacent to the second support this intersection taking place between the two support elements adjacent to the second support.
- the intersection may take place in plan view and in orthogonal projection in a substantially horizontal plane in the contact zone or in the portion of the support element connecting the frame to the contact zone.
- This situation can be repeated several times, in particular for at least 2, or even at least 3, or even at least 4, or even at least 5 or even at least 6 support elements of the first support, or even more.
- This configuration in transfer situation reflects a mutual intercalation of the two groups of support elements (group of the first support and group of the second support). It is also possible, when the two supports are in a transfer situation, seen from above and in orthogonal projection in a horizontal plane, at least one supporting element of the second support intersecting with the line tangent to the inner edges of two zones of contact support elements adjacent to the first support, this intersection taking place between the two support elements adjacent to the first support.
- intersection can take place in plan view and in projection orthogonal in a substantially horizontal plane in the contact zone or in the portion of the support element connecting the frame to the contact zone. This situation can be repeated several times, in particular for at least 2, or even at least 3, or even at least 4, or even at least 5 or even at least 6 support elements of the second support, or even more.
- This configuration in transfer situation also reflects a mutual intercalation of the two groups of support elements. According to this principle also, in a transfer situation and in top view, there is generally at least one pair of support elements adjacent to one of the two supports, such as the line segment passing through the center of their zone. contact is intersecting with a support element of the other support, generally its contact zone, this intersection occurring between the two neighboring support elements (forming a pair).
- This situation may occur for at least 2, or even at least 3, or even at least 4, or even at least 5 different pairs of support elements adjacent to one of the supports, it being understood that a support element may belong to two different pairs.
- This property also reflects the fact that the contact areas of the two supports are interposed at the time of transfer of the glass. The intersection may relate to the contact area or any part of the support element.
- This configuration in a transfer situation reflects a pronounced mutual intercalation of the two groups of support elements.
- the center of a contact zone is, in plan view, the center of gravity of the orthogonal projection of the contact zone on a horizontal plane. This center of gravity is also the geometric center or center of mass of the projection of the zone and can be called "centroid" or "geometry center” in English. This is the point on the surface of the projection of the area corresponding to the centroid of an object of the same shape and thickness infinitely thin and homogeneous in density.
- the “inner supporting contour of the first support” is a smaller touching virtual line, viewed from above and in orthogonal projection in a horizontal plane, the inner edge of any contact zone of the first support, including the passage itself.
- the length of this line is called the “inner support perimeter of the first support”.
- This line includes straight segments between the different contact areas including the passage itself.
- the “outer support contour of the second support” is a smaller touching virtual line, seen from above and in orthogonal projection in a horizontal plane, the outer edge of any contact zone of the second support, including the passage itself.
- the length of this line is called the "outer support perimeter of the second support”. This line includes straight segments between the different contact areas including the passage itself.
- the two supports when the two supports are in a transfer situation, viewed from above and in orthogonal projection in a horizontal plane, several contact zones of the second support are at least partially outside the inner support contour of the first support.
- the outer support contour of the second support in transfer situation and in top view, is at least partly outside the inner support contour of the first support. In particular, preferably, more than 50% or even more than 80% or even more than 90% of the outer bearing contour of the second support is outside the inner support contour of the first support.
- the inner perimeter of the contact areas of the first support may be less than 1, 2 times the outer perimeter of the contact areas of the second support, or even may be smaller than the outer perimeter of the contact areas of the second support.
- This situation is the consequence of the fact that the contact areas of the two supports are interposed in the manner of branches of two combs, the supports being in a transfer situation.
- the part of the frame of the second support carrying directly its support means (which excludes the arm) is generally circumscribed by the contact zones of the second support, in particular the outer support contour of the second support (And even all the contact areas), and yet the contact areas of the second support are found near the contact areas of the first support and in intercalation with the latter view from above.
- the part of the frame of the second support on either side of the passage (which excludes the arm and the part of the frame of the second support opposite the passage), is entirely circumscribed by the inner support contour of the first support, when the two supports are in transfer situation and in top view.
- the frame of the second support (and the support means of the second support) generally appears smaller overall and surrounded by the frame of the first support.
- the support means of the second support generally appears surrounded by the frame of the first support.
- the part of the frame of the second support on either side of the passage is entirely circumscribed by the upper part of the frame of the first support ( extended by a virtual line at the location of the passage), said portion directly bearing the support means of the first support, in top view and when the two supports are in a transfer situation.
- the frame of the first support may comprise a lower portion passing through the central zone of the first support in a view from above and in a transfer situation and connecting different parts of the first support in order to bring rigidity to the first support. This lower part must not interfere with the passage of the second support by a horizontal movement so that it places its support surface under the support surface of the first support in transfer situation.
- the frame of the first support may comprise a space located between a lower portion passing through the central zone and an upper portion comprising the support surface of the glass, this space being able to receive the second support. If, for the transfer of the glass, the first support first supports the glass, the second support is placed in this space in transfer position under the glass by a relative horizontal movement relative to the first support, then, it comes to take in charge the glass by a relative vertical upward movement. It comes out of space by this relative vertical movement, then taking the glass to the station planned for the rest of the process. If, for the transfer of the glass, the second support first supports the glass, the second support is placed in the space in the transfer position by a relative vertical movement relative to the first support, and it deposits by the same displacement vertical the glass on the first support. Then, the second support then empty, out of space by a horizontal movement. The two supports can then move away from each other.
- the glass keeps substantially the same horizontal orientation. It generally keeps this orientation substantially horizontal as long as it is supported by one or other of the two supports.
- the device according to the invention makes it possible to go from one support to another without influencing the geometry of the glass despite its high temperature.
- This horizontal movement of the second support can be generated from the arm that can be actuated by automatic mechanical means (such as a robot).
- automatic mechanical means such as a robot
- the use of a robot holding the arm is particularly advantageous because it allows the horizontal movement placing the second support in a transfer situation, then the relative vertical movement leading to the transfer of the glass, and then the removal of the second support relative to the first support, loaded or not glass.
- an arm can be connected to the second support, this arm can be manipulated by automatic mechanical means, in particular a robot, which is able to move horizontally and vertically the second support via the arm.
- the relative positioning of the supports for placing them in a transfer situation and the relative vertical movement of the supports can be achieved by moving the second support, in particular under the action of the automatic mechanical means, and via the arm.
- the passage provided in the support means of the first support so that the arm connected to the second support can pass during the transfer of the glass from one support to the other is generally less than 20% and even 15% of the internal support perimeter of the first support.
- Each of the supports may include a plurality of support members connected to the frame at one end and a contact area of the glass at the other end.
- the area of each contact zone of each support element may for example be in the range of 50 to 20 000 mm 2 .
- the shape of this area may be square or circular or other.
- the two supports may comprise a plurality of support elements.
- the area of each contact zone is advantageously in the range from 50 to 5500 mm 2 and more generally from 500 to 4000 mm 2 .
- any contact zone may be part of a circle of diameter 10 cm and more generally of diameter 80 mm.
- a support comprising a discontinuous support surface may comprise at least 4 support elements and therefore also four contact zones.
- one of the supports can in particular comprise 4 to 25 and more generally 4 to 20 support elements, in particular 6 to 20 support elements, more generally 8 to 20 support elements. each support element comprising a contact zone.
- the two supports may each include this number of support elements.
- the supports When the supports are intended to carry hot glass, especially just after bending, especially between 400 and 600 ° C, it is preferable that the supports have a relatively large amount of contact areas coming into contact with the glass at a distance relatively close to the edge of the glass, in particular not more than 200 mm from the edge, in particular not more than 170 mm from the edge, in particular not more than 150 mm from the edge, (without contact with the glass respectively beyond 200 mm, 170 mm 150 mm from the edge). At these temperatures, there is a risk that the contact areas mark the glass, this risk being even higher than the temperature of the glass is high. It is therefore generally necessary to reduce as much as possible the pressure of the glass (because of its weight), on the contact zones of the support elements.
- the contact zones could contact the glass in a contact strip between the edge (which includes the lower edge of the edge of the glass) and up to 200 mm from the edge of the glass and preferably up to 170 mm from the edge of the glass. edge, and preferably up to 150 mm from the edge, without contacting the glass, respectively beyond 200 mm or 170 mm or 150 mm of its edge.
- edge which includes the lower edge of the edge of the glass
- edge and preferably up to 150 mm from the edge, without contacting the glass, respectively beyond 200 mm or 170 mm or 150 mm of its edge.
- it may be advantageous for these contact zones not to come too close to the edge of the glass either, especially when the temperature profile of the periphery of the glass in the phase phase is not to be disturbed by the support.
- the contact areas could advantageously contact the glass in a contact strip substantially parallel to the edge of the glass, said contact strip being delimited by an outer virtual line and an inner virtual line.
- the limits of this contact strip are:
- - outer limit of the strip at least 50 mm and preferably at least
- inner limit of the strip at most 200 mm and preferably at most 170 mm from the edge of the glass and preferably at most 150 mm from the edge of the glass.
- the supports may have no contact with the glass outside of this contact strip when the supports are in a transfer situation (which means that the glass is exclusively in contact with the ambient air outside this contact strip).
- the outer and inner limits of this strip are substantially parallel to the edge of the glass.
- Each support can support the glass by contacting it exclusively in this contact strip without contact with the central zone of the glass (beyond 200 mm from the edge of the glass towards the inside).
- the support should have sufficient contact areas for the glass in the contact strip and distributed along the contact strip around the central glass area.
- the device according to the invention is particularly useful for supporting and moving a glass in the context of a glass bending and cooling process comprising gravity bending of the glass on a gravity support during which the glass rests on the glass.
- gravity support by the peripheral zone of its lower main face (facing downwards), said peripheral zone consisting of 50 mm from the edge of the lower main face, then separating the glass from the gravity support, then cooling the glass during which its lower main face is free from any contact in its peripheral zone, between a so-called higher homogeneous temperature temperature, of at least 560 ° C (preferably at least 575 ° C) and a so-called lower homogeneous temperature, d at most 500 ° C (preferably at most 490 ° C), said critical temperature range, the area of the main face less than one di stance greater than 200 mm from the edge being at a temperature at least equal to that of the peripheral zone at the moment when the peripheral zone reaches the higher homogeneous temperature.
- the device according to the invention is particularly useful for supporting the glass in the contact strip, during its cooling and while still in the critical temperature range.
- the glass can thus be conveyed by this device during its cooling by moving it from a warmer room to another colder room.
- the device according to the invention does not disturb the temperature homogeneity of the peripheral zone. In this way, it is possible to produce a final glass whose edge compression stresses in its sheet comprising the lower main face are greater than 8 MPa, or even greater than 10 MPa, and can even be up to 20 MPa, and are more homogeneous along the periphery of the glass.
- the extension levels can be significantly reduced, less than 5 MPa and even less than 4 MPa, or even less than 3 MPa.
- the area of a main surface of the glass is generally greater than 0.5 m 2 , especially between 0.5 and 4 m 2 .
- the central zone of the glass it is possible to place a virtual circle with a diameter of at least 100 mm and even at least 200 mm and even at least 300 mm, all points of which are more distant than 200 mm. mm of all edges of the glass, which characterizes a certain size of the glass.
- the glass generally has four edges (also called strips), the distance between two opposite edges being generally greater than 500 mm and more generally greater than 600 mm and more generally greater than 900 mm.
- the two supports are both provided with a plurality of support elements forming two groups, and that these two groups of elements must come into contact with the glass at a determined distance from the edge, the type of the strip contact mentioned above, then advantageously, at the time of transfer of the glass from one support to another,
- the elements of one group are shifted in relation to the elements of the other group, seen from above, (come out that they do not touch each other while crossing each other during the transfer),
- the elements of the two groups are interposed in a top view in the contact strip, in particular an element of a group having as neighbor at least one element of the other group and generally two elements of the other group (a neighbor on the other hand and else of him).
- the two groups of elements can intertwine in the manner of two combs during the relative vertical movement leading to the transfer of the glass from one support to another.
- the contact areas of the two supports appear interposed in the contact strip.
- the two supports can both comprise support elements comprising contact zones for all coming into contact with glass, especially glass, exclusively in a contact strip having a width of at most 150 mm, or even a width of not more than 100 mm or even of a width of not more than 80 mm, the contact zones of the two supports being at least partially interposed in the strip of contact in plan view and the supports being in a transfer situation.
- the support members are supported by a frame, it is necessary that the support members of the second support as well as the portion of the frame carrying the support elements directly can pass through the support surface of the first support during this movement. vertical. To do this, advantageously,
- the portion of the frame directly carrying the support elements of the second support (excluding the arm) is circumscribed by the support elements of the first support.
- the support means of the first support may be a peripheral track.
- This track is mainly continuous but includes a discontinuity forming the passage adapted to let the arm of the second support during the relative vertical transfer movement.
- the peripheral track can in particular carry the glass by contacting it only by the lower edge of its edge (said edge thus forming part of a contact strip between the edge of the glass and a certain distance from the edge of the glass, as already mentioned above. above), if it is desired to avoid contact with its lower surface in its peripheral zone (in particular in the case of hot glass at a temperature making it sensitive to marking). If, however, such a contact in the peripheral zone is not troublesome, then the peripheral track may come into contact with the lower surface of the glass.
- the support means of the second support may comprise a plurality of support elements fixed to the frame each comprising a contact zone of the glass, the whole of the contact zones forming a discontinuous support surface of the glass, all of the contact areas of the second support being circumscribed from above by the peripheral track during the relative vertical transfer movement.
- the support means of the second support may comprise a plurality of support elements fixed to the frame each comprising a contact zone of the glass, the whole of the contact zones forming a discontinuous support surface of the glass, all of the contact areas of the second support being circumscribed from above by the peripheral track during the relative vertical transfer movement.
- the support surfaces of the supports may comprise a fibrous material, in particular of the openwork knit type (called by the skilled person "quenching knit"), suitable for contacting the glass, especially at a temperature between 400 and 600 ° C. It is perforated to the extent that one can even distinguish the plate on which it is fixed through some of its meshes.
- the support elements of one and / or the other of the supports may comprise a means of mobility of the contact zone for the glass under the effect of the weight at the moment of its reception by the support, modifying the orientation of the contact zone of the glass and / or damping the reception of the glass by the support.
- This means may include a spring.
- the invention also relates to a method for supporting and generally conveying glass comprising its support by the device according to the invention, comprising
- the two supports can move away from one another, one of the supports carrying the glass.
- the invention relates to a method for supporting and generally conveying glass comprising its support by the device according to the invention, comprising
- the invention also relates to a method for supporting and generally conveying glass comprising its support by the device according to the invention, comprising
- the two supports can move away from each other, the first support carrying the glass.
- the glass can be any type of glass, clear or tinted, coated with at least one layer, enamelled or unglazed.
- the glass can be used for any application in the field of vehicles to act as windshield, rear window, side window, quarter, roof, bayflush or other. Glass can also be used in any non-automotive field such as building, solar, specialty applications, aeronautics, ceramic hobs, etc.).
- the glass may have any thickness (generally in the range of 1 to 100 mm) and be of any size, with no limit of thickness or dimensions of principal faces.
- the glass may comprise four strips (that is to say four edges or four sides), as is the case of windshields and rear windows of motor vehicles, these strips are not necessarily parallel in pairs, nor linear.
- the passage provided in the support means of the first support so that the arm of the second support can pass during the transfer of the glass from one support to the other is generally comprised entirely in a side corresponding to one of these bands when he carries the glass (while under the glass of course) and is usually in the middle of that side.
- the support surfaces of the two supports may each comprise four sides. It is the same for the inner support contour of the first support and the outer support contour of the second support.
- the passage of the support means of the first support is generally fully contained in one of the sides of its support surface and is generally placed in the middle of this side. This also corresponds to one of the glass bands. In transfer situation, the passage is under a strip of glass.
- the support according to the method can intervene in the frame of the manufacture of the glass, requiring its handling of a station of treatment to another. It may include a cooling treatment after bending.
- the glass may be at a certain temperature in a chamber on the first support, then the second support comes to get it away from this room and take it to a cooler area.
- the transfer of the glass from one support to the other can take place while the glass is at a temperature between 400 and 600 ° C.
- the term “inside” always means towards the center of the supports or glass, the term “outside” meaning towards the periphery of the supports or the glass.
- the invention also relates to a device as already described, except that the passage in the first support is not necessarily present or necessary. Indeed, at least one vertical arm connected to one of the supports and acting under it, can also be responsible for raising or lowering one or the other of the supports to effect the transfer of the glass from a support to the other.
- This variant is not preferred since the use of an arm for moving the second support horizontally and vertically is particularly advantageous. All the technical characteristics of the supports already described (except the passage) are applicable to this variant, being able, if necessary to make the object of a divisional application.
- this variant may relate to a device for supporting glass, comprising a first support and a second support, each of these supports comprising a frame and a support means for the glass connected to the frame, the support means of each support comprising a surface the two supports being able to be animated with a relative vertical transfer movement allowing the support surface of one to pass above or below the support surface of the other so to carry out the transfer of the glass from one support to the other, the support means of the two supports each comprise a plurality of support elements fixed to the frame and each comprising a contact zone of the glass, all the zones of contacting the support elements of a support forming a discontinuous support surface of the glass, and so that during the relative vertical transfer movement, there is, seen from above, at least one supporting element ien of the first support intersecting the line tangent to the outer edges of two contact zones of support elements adjacent to the second support, this intersection taking place between the two neighboring elements.
- This situation is preferably for at least 2 or at least 3 or at least 4 or at least 5 or at least 6 support members of the first support.
- the support means of the first support comprises (due to the discontinuity of its support surface) a passage capable of passing an arm connected to the second support during the relative vertical transfer movement, the use of a passing arm laterally through such a passage, although preferred, is not necessarily necessary.
- This variant is applicable to media that can be interposed in "Comb" as already described. All the technical characteristics already described are applicable to this variant.
- Figure 1 shows a side view of a stack of two curved glass sheets 1 supported by a support comprising a support surface 2 of the peripheral track type.
- This support is rather a support of the "first support” type within the meaning of the invention.
- the peripheral track 2 is fixed on a chassis 3.
- this frame provides a space 4 in which another support of the "second support” type within the meaning of the invention can pass through a horizontal movement to be placed in a transfer situation. and come to take charge of the glass by an ascending relative vertical movement.
- the frame 3 comprises an upper portion 5 directly supporting the support means of the first support and which completely circumscribes the second support when it is in the space 4 (see Figure 3).
- the frame 3 comprises a lower portion 6.
- This lower portion 6 can pass through the central zone of the first support in plan view and connect different parts of the first support in order to provide rigidity. This lower part 6 does not interfere with the passage of the second support by a horizontal movement so that it is placed in a transfer situation, its support surface being under the surface of the support of the first support.
- FIG. 2 represents, in perspective, a support of the "second support” type within the meaning of the invention.
- This support comprises a frame 20 provided with an arm 21.
- This frame comprises support elements 22 connected to the frame 20 by one end 23 and a contact zone 24 for the glass at the other end. Viewed from above, the support elements 22 are directed outwardly from the frame 20 (at the end 23) to the contact zone 24.
- FIG. 3 represents the supports of FIGS. 1 and 2 in transfer situation in plan view.
- the same elements of Figures 1, 2 and 3 have the same reference numbers.
- the second support of Figure 2 can go through the space 4 ( Figure 1) by a first horizontal movement, then support the glass carried by the first support up. Indeed, the arm 21 can pass through the passage 30 formed in the support means 2 of the first support.
- the virtual line 31 representing the outer contour of the contact areas of the second support is circumscribed seen from above by the line 32 representing the inner support contour of the first support. None therefore hinders the upward vertical movement of the second support so that it can take charge of the glass by unloading the first support.
- the inner support contour of the first support includes all inner sides 32 of the first support completed by the virtual line segment 34 passing through the passage and connecting the two edges of the support 2 forming the passage.
- the width 33 of the passage 30 is less than 20% of the inner support perimeter of the first support.
- the second support (of Figure 2) can carry the glass then be placed above the first empty support then down and unload the glass leaving it on the first support, then, by a horizontal movement out of the space 4 and move away empty.
- the support surfaces of the two supports each comprise four sides. In the case of the second support, these sides are more apparent from the virtual line 31.
- the passage of the support means of the first support is entirely comprised in one side and is in the middle of this side.
- FIG. 4 shows in a sequential manner how a second support 40 can support a curved glass while the latter is carried by a first support 41.
- the two supports have as a support surface a plurality of support elements fixed on their chassis.
- the second empty support 40 manipulated by a robot (not shown) actuating the arm 46, approaches the first support 41 carrying a curved glass sheet 47.
- the second support 40 comprises a frame 42 carrying a plurality of support members 43. These support members 43 are connected at one end 44 to the frame 42 and have at their other end a contact zone 45 for engaging the glass.
- the support elements 43 are directed towards the outside of the chassis 42 when going from the end 44 to the end 45.
- the first support 41 carries a glass sheet 47 by a plurality of Support members 48.
- This first support 41 comprises a frame 50.
- the support elements 48 are connected at one end 49 to the frame 50 and have at their other end 51 a contact zone for coming into contact with the glass.
- the support elements 48 are directed towards the inside of the frame 50 when starting from the end 49 to go to the end 51.
- the frame 50 comprises a space 52 to allow the support 40 to go through a horizontal movement and position themselves under the glass.
- the support 40 can then mount (see phase c)) without being blocked, thanks to the passage between the support elements 48 allowing the arm to pass.
- the two supports are in a transfer situation, the second support 40 being placed under the glass without yet touching it.
- the second support 40 whose arm 46 is actuated by a robot, is mounted and has supported the glass 47, the first support 41 being discharged.
- This is made possible by the passage in the frame 41 passing the arm 46 of the second support 40, and thanks to the fact that the support elements 43 (second support) and 48 (first support) are shifted in view of them, the elements of support 43 going outwardly from the frame 42 while the support members 48 are inwardly from the frame 50.
- the upper portion of the frame 50 does not obstruct the rise of the support 40 because it completely circumscribes the second support (off the arm).
- the support elements 43 on the one hand and the support elements 48 intersect in the manner of branches of two combs.
- the support elements 43 and 48 preferably have their contact area adapted to the shape of the glass they receive, that is to say that their contact area is oriented like glass and is therefore substantially parallel to the supported area glass. These support elements may further include a spring to dampen the reception of the glass at the time of its handling.
- FIG. 5 shows, viewed from above and in orthogonal projection in a horizontal plane, the supports 40 and 41 of FIG. 4 at the time of the transfer of the lens 47 from one support to the other.
- This glass has four nonparallel strips two by two. We observe that:
- the frame of the second support 40 is circumscribed by the frame of the first support 41 (outside the arm 46);
- the frame of the second support 40 is circumscribed by the contact zones 51 of the support elements 48 of the first support;
- the support elements 48 of the first support are directed inwards from the frame 41 of the first support,
- the support elements 43 of the second support are directed outwards from the frame 40 of the second support,
- the support elements of the two supports are offset in plan view, support elements of the two groups (group of support elements 48 of the first support and group of support elements 43 of the second support) are interposed top view, most elements of a group having as neighbors two elements of the other group,
- d1 may especially be zero or preferably at least 50 mm and preferably at least 6 cm and even at least 7 cm and d2 may in particular be at most 200 mm or preferably at most 170 mm and even at most 150 mm.
- the support element 51 of the first support intersects the line tangent to the outer edges of two contact zones 55 and 56 adjacent to the second support, the intersection having place between contact areas 55 and 56.
- two support elements adjacent to one of the supports are such that the segment passing through the center of their contact zone passes through the contact area of the other medium. This is particularly the case of the line segment 57 passing through the center of the contact areas 55 and 56 of the second support and which passes through the contact area 51 of the first support.
- the elements of construction which have just been mentioned show the intercalation of the contact areas of the two supports allowing them to intertwine in the manner of branches of two combs during the vertical movement leading to the transfer of the glass from one support to the other.
- FIG. 6 represents a view from above of the same device as in FIG. 5, the two supports being in a transfer situation.
- the same elements in Figures 5 and 6 have the same references.
- the virtual line 62 is the inner support contour of the first support, touching, seen from above (in orthogonal projection in the horizontal plane) all the contact areas 51 of the first support.
- the virtual line 60 is the outer supporting contour of the second support, which surrounds and touches, seen from above (in orthogonal projection in the horizontal plane) all the contact zones 63 of the second support. It can be seen that more than 90% of the outer support contour of the second support is outside the inner support contour of the first support (this respective position of the two contours is not verified only in the upper right corners and left of Figure 6).
- the two groups of support elements are interposed in top view and the contact areas of the two supports support the glass at substantially the same distance from the edge of the glass in the same contact strip.
- the width 53 of the passage is less than 20% of the length of the line 62.
- the passage is entirely in one side of the first support and the glass in top view, the supports being in a transfer situation.
- FIG. 7 shows a support element 70 that can equip a support according to the invention.
- the support member 70 comprises at a lower end a base 71 provided with orifices for attachment to a frame (not shown).
- the other end comprises a pad comprising a plate 72 for receiving a fibrous material 79 to come into contact with the glass to be supported, in particular glass.
- This refractory openwork material (it is said perforated because the air can pass easily between its mesh, the plate 72 being even visible through the mesh), said "quenching knit", is maintained on the surface of the element by pins 73, as can be seen in Figure 3c).
- the contact zone 78 is movable in translation in a direction perpendicular to it and its downward movement is accompanied by the compression of a spring 74 forming a mobility member between the base and the shoe formed by association of the plate 72 and fibrous material 79.
- This movement in a direction perpendicular to the contact zone 78 is the only degree of freedom of the pad relative to the frame. In practice, it may be useful to orient this element so that the axis of the spring is substantially perpendicular to the supported local area of the glass received, so that the contact zone 78 is substantially parallel to the local surface supported. Thus, the reception of the glass by the contact zone 78 is damped by the spring 74.
- FIG. 3 b we see the same support element as in FIG.
- FIG. 8 shows a support element 80 that can equip a support according to the invention. It is intended to be fixed on a frame by a base 86.
- this element is similar to that of Figure 7, except that the spring 81 is a wave spring and is not guided in the direction of its axis. It can therefore compress in the direction 82 of its axis, but in addition, this spring offers degrees of freedom 83 tilting of the pad from any side around the axis of the spring.
- the contact zone 84 to be equipped with a refractory fibrous material held by the lugs 85 as for the element of FIG. 7c
- the contact zone 84 is automatically oriented to become parallel on the local surface of the supported glass.
