Definitions

  • the present invention relates to an automatic machine and an automatic method for localized removal of coatings deposited on glass plates.
  • Removal is performed in order to allow valid adhesion of the sealants to the glass, said sealants being used particularly to compose the insulating glazing (or double-glazing unit in the jargon), also described hereinafter.
  • the coating is constituted typically by multiple layers of metals and metallic oxides of atomic thickness deposited by means of nanotechnology processes, for example with the sputtering technique, and are anchored physically and chemically to the glass; however, since some layers can be easily oxidized, this anchoring to the glass is vulnerable with exposure to atmospheric agents, such as in particular humidity.
  • the double-glazing unit the composition of which will be explained hereinafter, inhibits atmospheric contact, since the coated surfaces are oriented inward, the part of the glass plate, and of the coating with it, that constitutes the perimetric edge, although it has a moderate extension in the transverse direction (hundreds of angstroms), reacts with the atmospheric agents and is exposed to oxidation.
  • the coating therefore, has to be removed at the perimetric margin intended for the sealants. This removal must be complete in order to ensure the adhesion of the sealants and must have an esthetically pleasant finish because it is visible in all cases in which the glass plates are exposed in their entirety because they are not masked by the frames; this completeness does not occur with currently commercially available machines.
  • the glass plate In order to better understand the configuration of the glass plate, not so much in its possible isolated use but especially in its use in combination with other components to constitute what is called a double-glazing unit, some concepts regarding the semifinished product, i.e., the glass plate, and the final product, i.e., the insulating glass commonly termed double-glazing unit, are summarized hereafter.
  • the subsequent use of the double-glazing unit i.e., as a component of door or window frames or of continuous glazing or structural glazing, is known to the person skilled in the art and is not discussed in detail here.
  • the double-glazing unit is constituted typically by two or more glass plates 1001, 1002, etc., mutually separated by one or more spacer frames 1003, etc., which are internally hollow and are microperforated on the face directed toward the inside of the chamber.
  • the spacer frames 1003 contain, in their hollow part, hygroscopic material, not shown in the figure, the task of which is to absorb humidity.
  • the chamber (or chambers) 1007 delimited by the glass plates 1001 and 1002 and by the frame 1003 can contain air or gas or mixtures of gases injected therein, which give the double-glazing unit particular properties, for example thermal insulation and sound-insulating properties.
  • a spacer profile 1003 has spread which has an essentially rectangular cross-section or a rectangular cross-section with two recesses and is made of expanded and flexible synthetic material (by way of non-limiting example:
  • Figure 1 shows five of the many possible sectional views of double-glazing unit configurations 1a, 1b, 1c, 1d, 1e, only the first and last of which have been commented. However, it is straightforward to extend the above description to the configurations 1b, 1c, 1d, in which there are either multiple frames or offset or laminated glass plates.
  • the sun represents schematically the external environment of a building in which the double-glazing units are installed, while the inside of the building is represented schematically by a radiator.
  • the glass plates used in the composition of the double-glazing unit can have different shapes as a function of use; for example, the external glass 1001 (with respect to the building) can be standard or selective or reflective glass (in order to limit the thermal intake during the summer months) and can also be laminated/armored glass (for intrusion/vandalism prevention functions) or can be laminated/toughened glass (for safety functions) and also combined, for example reflective and laminated glass, as well as offset with respect to the internal glass plate or the intermediate glass plate.
  • the external glass 1001 can be standard or selective or reflective glass (in order to limit the thermal intake during the summer months) and can also be laminated/armored glass (for intrusion/vandalism prevention functions) or can be laminated/toughened glass (for safety functions) and also combined, for example reflective and laminated glass, as well as offset with respect to the internal glass plate or the intermediate glass plate.
  • the internal glass plate 1002 (with respect to the building) can be of the standard or low-emissivity type (in order to limit the dissipation of heat during winter months) and can also be laminated/toughened glass (for safety functions) and also combined, for example low-emissivity and laminated.
  • the properties related to thermal insulation, both under winter conditions (low emissivity) and under summer conditions (selective), as well as the properties related to light transmission, are obtained by means of deposits of metals and metal oxides, generally multilayer ones, with a total thickness on the order of hundreds of angstroms, which however must be removed in the perimetric portions for interaction with the sealants.
  • This edging besides being performed as described earlier, i.e., in the production lines of the double-glazing unit, can also be performed before the cutting of the glass plate from the commercial format to the formats for use of the insulating glass.
  • This solution is adopted if the bands to be edged have a limited width.
  • DE 196 32 240 A1 which relates to a working head equipped with a tandem of two floating tools (cylindrical grinding wheels) of different widths, so as to select two widths of the edging bands as a function of the region of the plate being edged, before it is divided into the final formats, such as for example 20 mm in the internal regions of the plate and 10 mm along the external perimeter, the inner bands being subsequently scored and separated longitudinally along the central axes, thus obtaining the 10-mm margin.
  • the aim of the present invention is therefore to solve the highlighted technical problems, eliminating all the drawbacks according to the background art and therefore devising an automatic machine and an automatic method that allow edging of the margins of glass plates in a reliable, repetitive, qualitatively perfect manner, which is lacking in the background art, and last but not least in an economical manner.
  • a further object of the present invention is to avoid altering the structure of the production line of the insulated glazing, taking advantage of the modularity that typically characterizes it.
  • Another object is to perform grinding in a manner consistent with the shape of the perimetric profile of the glass plate even when it is non-rectangular, due to the presence of inclined sides and of curvilinear portions.
  • an automatic machine for edging the margins of substantially flat glass plates, characterized in that it comprises a machine body and at least one working head, adapted to carry at least two tools arranged in series with respect to each other, i.e., in succession with respect to the working direction, said tools being in floating contact with the margins of the glass plate and being movable, each one independently of the other or others, toward and away from the margin of the glass.
  • the relative movement between said at least one working head and said glass plate 1 constitutes, in the etymology of machine tools, the feed movement or forward movement.
  • the second movement is the one imparted to the tool (grinding wheel) with an autonomous control.
  • a further movement is used to position the tool with respect to the external margin of the glass plate, both for edging in which the band corresponds to the thickness of the tool (grinding wheel), in which case the external margin of the tool corresponds to the edge of the glass or the edge of the chamfer of the glass, and for edging in which the band is greater than the thickness of the tool (grinding wheel), in which case there have to be multiple passes until the desired extension of the edging is covered; this registering movement is obtained by means of the initial arrangement of the axes that actuate the relative movement described earlier.
  • the processing of glass plates having a non-rectangular shape for example a polygonal shape composed by all rectilinear sides, or a multiform shape, i.e., composed of rectilinear or curvilinear portions, preferably but not exclusively with a base portion constituted by a rectilinear side, is allowed; in the first case (polygonal, including the rectangle), by activating the tools referenced by the subscript a (front) for a rough grinding pass and the ones referenced by the subscript p (rear) for a finishing pass, simultaneously, in the second case (multiform), by activating the tools, the first one with the subscript a (front) for a rough grinding pass and the second one with the subscript p (rear) for a finishing pass, in successive steps because only one can be coupled tangentially to the perimeter, which is not rectilinear, of the glass plate, this occurring due to the combined action of the horizontal translation axis H, of the vertical translation axis V,
  • the glass plate is arranged vertically, rests on a sliding surface and can move horizontally on a conveyor.
  • the arrangement described as vertical is actually slightly inclined with respect to the vertical plane (generally by 6°) in order to give static stability to the glass plate, i.e., prevent its tipping.
  • one or more glass plates are of the coated type (low-emissivity or selective)
  • said coating shown by emphasizing its thickness, which in reality is only a few hundred angstroms, is interrupted or rather eliminated at the region affected by the sealants and the adhesives. This is to make the adhesion of the sealants and adhesives to the glass plates 1 efficient and stable over time.
  • the coating layer in fact, would be subjected over the years to an oxidation starting from the external edge of the glass plate that would entail a separation from it. Since the large source glass plates from which the formats of the target glass of the required dimensions are obtained in order to compose the insulating glazing unit are coated over their whole extension, this applies also to the target formats and therefore it is necessary to perform removal at the region intended to interact with the sealants.
  • single-digit numerals designate the main components of the machine (two-digit figures designate the assemblies without subassemblies) so as to have a global overview thereof, the numeral 1 being reserved for the glass plate as material that is the subject of the processes and the numeral 2 being reserved for the machine body that performs its grinding process, while the details and the constructive mechanisms and the devices, such as the motors, the pneumatic cylinders, the sensors, etc., are designated by three-digit numerals in which the first digit is the digit of the main assembly to which it belongs (100 for the lower working head, 200 for the upper working head, 300 for the assembly for rotation about the axis J, 400 for the assembly for movement along the vertical axis V and 500 for the assembly for movement along the horizontal axis H) and four digit numerals designate the components of the double-glazing unit (1001 the external glass, 1002 the inner glass, 1003 the spacer frame and then the sealants (1004 the sealing butyl, 1005 the strength
  • the numeral 1 designates the single glass plate, the sides of which are respectively designated: the vertical front side 1a, the horizontal longitudinal sides, 1b the upper one and 1d the lower one (which can also be processed simultaneously in a machine option), and the vertical rear side 1c.
  • front and rear refer to the direction of the flow of the material being processed (glass plate 1) within the production line of the double-glazing unit.
  • front and rear are also used with reference to the face of the glass plate 1 as viewed by the operator.
  • the machine comprises a main body 2 connected in a cascade arrangement between two conveyors 2a and 2b, arranged respectively upstream and downstream of the machine body 2.
  • the input conveyor 2a is connectable to an upstream processing section, for example the section for cutting the glass from the dimensions of the source plates to the dimensions of the target plates, or the glass plate 1 to be edged can also be loaded manually or by controlling a handling unit on the input conveyor 2a.
  • an upstream processing section for example the section for cutting the glass from the dimensions of the source plates to the dimensions of the target plates, or the glass plate 1 to be edged can also be loaded manually or by controlling a handling unit on the input conveyor 2a.
  • the output conveyor 2b instead can be connected to a downstream processing section, for example the section for grinding the edges or the washing unit.
  • the conveyors as well as the central machine body, maintain the plate at an inclination of approximately 6 degrees with respect to the vertical, as can be seen in Figures 2 and 3 .
  • the input conveyor 2a comprises a base for supporting the lower edge of the glass plate, on which a series of motorized support and conveyance rollers or belts of the known type is arranged.
  • the conveyor comprises furthermore a resting surface with idle wheels or an air bearing, also of the known type, on which the glass plate is rested in a substantially vertical manner, in the sense mentioned above.
  • the input conveyor comprises preferably a thickness detector of the known type (not shown), which uses a potentiometer associated with a pad which, by means of the action of a pneumatic cylinder, is moved into contact with the front face of the glass plate, the rear face resting against the vertical reference plane 2a, in order to measure the thickness of the glass plate 1 to be processed before it enters the edging section, so as to provide a signal for the initial approach of the abrasive tools to the glass plate 1 as a function of its thickness, which typically is variable in the range of 3 to 40 mm.
  • this information regarding the thickness of the glass plate 1 can come from an information system or can be set manually by the operator by means of the control post 12.
  • the machine body 2 comprises a section 2c of the known type constituted by a resting surface with a pseudovertical disposition with idle wheels for the support and sliding of the rear face of the glass plate 1, to contrast the thrust of the abrasive tools.
  • the working heads are designated by the sections 100 and 200 and will be described in detail hereinafter.
  • the machine body 2 contains a section 500 that comprises a conveyor 501 with rollers that are partly motorized and partly idle of the known type with horizontal axes or with belts (inclined by 6° with respect the horizontal plane), for the support and traction of the glass plate 1 along the horizontal (longitudinal) axis H.
  • the machine body 2 contains also a section 400 that actuates the vertical movement along the axis V of the working head of the section 200.
  • the machine body 2 contains also a section 300 for the swiveling and rotation of the section 200 about the axis J at right angles to the glass plate.
  • the glass plate 1 that arrives from the preceding processing machine (or loaded manually or by means of a handling unit on the input conveyor 2a of the machine) is caused to advance, conveyed by the support and conveyance system of the type 501 of the conveyor 2a of the body 2.
  • the vertical plane with idle wheels or air bearing for the sliding of the input conveyor 2a and output conveyor 2b are taken from the section 2c described earlier in the solution with idle wheels.
  • the glass plate 1 is thus conveyed to the position in which a carriage actuated by the synchronous motor 503 and by a chain of known kinematic systems 504, 505, 506, 507, 508 engages with the sucker 502 said glass plate in its rear face and subsequently moves it with a synchronous axis along the direction H.
  • This control of the position of the glass plate 1 is important for the correct operation of the process performed by the working heads 101a, 101p and 201a, 201p, as will become apparent in the continuation of the description, so as to coordinate the synchronous movements: the horizontal movement H of the glass plate 1, the vertical movement V, and the rotational movement of the working heads 201a, 201p, necessary so that the edging tools 202a and 202p are always mated with the perimeter of the glass plate 1 having a rectangular shape (1 as shown in Figure 11a ), in which case the rotational axis J performs discrete rotations by 90°, or having a non-rectangular shape (1',1",1"' as shown in Figures 11b, 11c, 11d ), in which case the rotational axis J performs discrete rotations at the cusps of the glass plates and continuous rotations at the curvilinear portions of the glass plates.
  • Figures 4 and 5 relate to the working head 200 containing the tool bodies 202a and 220p fixed to the spindle 310 by means of the brackets 309a, 309p, in a floating manner on the axes 203a, 203p.
  • the spindle 310 is replaced by a support fixed to the plate 307.
  • the cutting motion T is transferred to the tools 201a, 201p by means of the kinematic systems constituted by the motors 211a, 211p, with variable speed in order to optimize the performance as a function of the type of coating to be removed (ground) and of the characteristics of said tools and the other processing parameters, on the axes of which said tools are keyed.
  • the swiveling of the tool bodies 201a, 201p has two components, in detail: the first of linear registration R', rather than actual swiveling, in order to arrange the work field of the tools as a function of the thickness of the glass (which has been measured in the input conveyor 2a, as mentioned earlier), which is done by the motor 206 that actuates the actuator 207 that moves the slider 307 with a feedback coming both from the potentiometer 308 and from the linear sensors 205a, 205p with which the pneumatic cylinders 204a, 204p are provided, which identify the start and the extent of the stroke thereof; the second component R" of soft oscillation, in order to adapt to the irregularities of the face of the glass plate, which is done by the pneumatic cylinders 204a, 204p pivoted on the brackets 309a, 309p connected to the spindle 310 and operating on the swiveling arms 206a, 206p of the tool bodies 201a, 201p.
  • An essential characteristic of the floating movement is that it occurs in such a configuration as to keep the active face of the tools 202a, 202p in conditions of theoretical coplanarity with the face of the glass plate, so that the operation of the active parts of the tools, designated by the segments La and Lp in Figure 6 , due to the floating behavior, compensates the undulations of the face of the glass plate 1 in the direction of the thickness of said plate, while the non-parallel arrangement of the tool segments La and Lp in contact with the face of the glass plate is compensated by the softness of said tools 202a, 202p, obtaining therefore one of the important characteristics of the present invention: i.e., that of removing the infinitesimal thicknesses of the coating on the margin of the glass plate, the planarity of which cannot be identical to that of the tool no matter how precise the execution of the kinematic systems might be (it is a matter of removing uniformly thicknesses on the order of hundreds of angstroms).
  • the machine can use two working heads, a lower head 100 with a fixed arrangement (relative to the axis V and the axis J) and an upper head 200 that can move rotationally along the axis J and vertically along the axis V.
  • the components of both of these working heads are identified in the description given earlier for the upper working head and any further description is unnecessary, except for completing what relates to the rotation of the vertical working head 200 about the axis J as visible in Figure 6 and the translation of said working head along the vertical axis V as shown in Figure 7 .
  • the mechanisms for the rotation of the working head 200 are the ones that belong to the slider 307 and consist of the hollow support 306 that defines the axis J by means of the spindle 310 that rotates on the bearings 305 accommodated in said hollow support under the actuation of the synchronous motor 301, which operates on the tool bodies 201 a, 201p that are integral with the spindle 310, as regards rotation, by means of a reduction unit 302, a pinion 303 and a ring gear 304.
  • This rotation makes it possible to orient the working head 200, and with it the tools 202a, 202p, so as to mate with the perimeter of the glass plate 1, in a successive manner by performing rotations by 90° in the case of glass plates 1 having a rectangular shape, in a progressive manner by means of the interaction and interpolation of the axes H, V, and J in the case of glass plates having non-rectangular shapes 1', 1", 1"'.
  • the slider 405 of Figure 7 carrying the working head 200 is moved along the guides 407, to which it is coupled by means of the sliding blocks 406, by means of the kinematic chain: synchronous motor 401, reduction unit 402, pinion 403 that meshes with the rack 404.
  • OPTION 1 (one working head 200): the diagrams of Figures 9a to 9n show, as anticipated in the description of the figures, both the front tool 202a and the rear tool 202p, with filling when in the active step and without filling in the resting step; the shaded area instead represents the side or that part of the side of the glass plate that has already been ground.
  • OPTION 2 (two working heads 100, 200): the diagrams of Figures 10a to 10f show, as anticipated in the description of the figures, the front tool 102a and the rear tool 102p of the first working head 100 and the front tool 202a and the rear tool 202p of the second working head 200, with filling when in the active step and without filling in the resting step; while a shaded area represents the side or part of the side of the glass plate that has already been ground.
  • OPTION 3 (case to be embodied preferably with only one working head): everything proceeds as in the description of option 1, except that in order to incline some sides, for example the non-vertical side 1a, the non-horizontal side 1b, etc., the axes H, V + J work interpolated by means of the linked actuation of the motors, which perform synchronous motions: 503 (which operates the sucker 502 along the axis H), 401 (which operates the working head along the axis V), 301 (which operates the working head in the rotation about the axis J).
  • the axis J it is used to orient the pair of tools 202a, 202p so that it is tangent to the polygonal broken line to be followed and operates in a discontinuous manner at each cusp (preceded by movements of the plate and of the working head similar to those described in option 1).
  • the tools can therefore operate simultaneously (always in the front-rear succession) because the rotation of the working head, although performed at the centerline of the front tool 202a, entails maintaining tangency, since the sides are rectilinear, for both of the tools; see Figure 13 for clarification.
  • the linking of said motors occurs by means of electronic drives managed by software, said software having received as inputs all the information regarding the shape 1' of the glass plate, with known methods such as bar codes, databases, network, scanner, etc..
  • the lower side, which for these shapes must be horizontal for using the belt conveyor or the roller conveyor 501, is instead processed in a manner that is not interpolated but still synchronous by the pair of tools 202a, 202p while the glass plate 1' moves along the axis H, or by the pair of tools 102a, 102p in the case of a machine with two working heads.
  • OPTION 4 everything proceeds as in the description of option 2, except that in order to follow the inclination of some sides, for example non-horizontal or non-vertical sides 1a and now in particular the curvilinear shape of some other sides, the axis H, V, ⁇ operate interpolated by means of the linked actuation of the motors 503, 401, 301, which now operate in a synchronous manner, as in the case of the oblique sides in the methods according to option 3, but with a continuous variation of the axis J in order to orient the tools 202a in the first pass and 202p in the second pass, in a tangent manner with respect to the curvilinear shape to be followed, in the case of curvilinear parts.
  • the lower side which must be horizontal for these shapes in order to use the belt conveyor or the roller conveyor 501, is instead processed in a manner that is not interpolated but still synchronous by the pair of tools 202a, 202p, while the glass plate 1" moves along the axis H, entrained by the sucker 502, or by the pair of tools 102a, 102p in the case of the machine with two working heads.
  • This partially curvilinear glass plate shape is ground by complete paths of one tool at a time, i.e., it is subjected to multiple processing cycles (at least two, or more if the degree of processing requires a sequence of more than two tools, for example in the case of coatings that are particularly difficult to remove). It goes without saying that if the band to be ground is greater than the width of the tools, the cycle or cycles must be repeated on paths that are parallel to the one started first, until said band is covered progressively, possibly with a little overlap at the offset of the parallel paths. This clarification obviously concerns all five options.
  • this shape of a glass plate which is completely curvilinear, can be ground by means of complete paths of one tool at a time, i.e., it has to be subjected to multiple processing cycles (two or more if the degree of processing requires a sequence of more than two tools, for example in the case of coatings that are particularly difficult to remove).
  • OPTION ON THE OPTIONS OPTIONS 4 and 5 that consider curvilinear shapes of the glass plates can be obtained with a machine and a method that use three rotation axes ⁇ ⁇ ⁇ instead of a single rotation axis J.
  • each tool 202a, 202p with its own rotation axis at right angles to the glass plate passing through the centerline of the tool/plate contact segment, ⁇ for the tool 202a and ⁇ for the tool 202p, so as to simplify the linking among the axes H, V, ⁇ , during the first processing pass performed with the front tool and among the axes H, V, ⁇ , during the second processing pass performed with the rear tool, in the cases of curvilinear shapes according to OPTIONS 4 and 5, and of providing the entire cradle 307 with a third rotation axis, again at right angles to the glass plate, ⁇ , which in practice is J, in order to rotate the working head for the cases of the rectilinear sides according to OPTIONS 1, 2, 3.
  • the invention is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
  • This includes, for example, the quantity of tools that can be extended to more than two, the mechanical solutions for the feeding motions of the tools, the support and conveyance of the glass and the actuation means, which can be electrical, electrical-electronic, pneumatic, hydraulic and/or combined, while the control means may be electronic or fluidic and/or combined.
  • An important constructive aspect is the logic combination of the actuations respectively for translation of the glass, for movement of the working head 200 so as to allow the processing of contoured glass plates, i.e., plates having non-rectangular shapes.
  • the electric drives of the motors dedicated to the axes H, V, J are linked by means of an electric axis, with numeric control.
  • the tools 103a, 103p, 203a, 203p can have a shape and dimensions that are different from those indicated in the figures and can be constituted of mixes with different elasticities and deformabilities.
  • the constructive details can be replaced with other technically equivalent ones.
  • the materials and the dimensions may be any according to the requirements, particularly arising from the dimensions (base, height and thickness) of the glass plates 1 or from the dimensions and shapes of the glass plates 1', 1", 1"'.
