Definitions

  • the present invention relates to an automatic machine and an automatic method for the sealing of the perimetric rim of an insulating pane.
  • the operation can likewise concern glass sheets 2M, 2'm with different sizes while still belonging to the same insulating pane so as to obtain a staggering between their edges, which is necessary for coupling with a particular type of window or door frame, i.e. the type that constitutes what is called continuous panes or what is called structural panes. And it is particularly, though not exclusively, for these types of offset insulating panes that the invention is remarkably innovative.
  • the rigid frame 3 or the flexible spacer profile 5 for forming what is called the insulating pane 1 for forming what is called the insulating pane 1, hereinbelow a brief description is given of some concepts regarding the semi-processed products, i.e. the glass sheet 2 and the frame or the spacer profile 3, 5 and the final product, i.e. the insulating pane 1, assuming the subsequent use of the insulating pane, i.e. as a component of the window or door frame, is known. In order to rationalize the description it is easier to begin with the final product and proceed to break it down into its constituent elements.
  • the insulating pane 1 is constituted by the composition of two or more glass sheets 2, 2', 2,", 2'", etc., which are separated by one or more spacer frames 3, 3', 3", etc., which are generally made of inorganic material like aluminum or stainless steel or an inorganic/organic mixture, the latter generally being PVC (polyvinyl chloride, but other substances are possible), are generally hollow and microperforated on the face directed inward, the spacer frames containing, in the hollow part thereof, hygroscopic material 4, and being provided with a butyl sealant 6 on the side faces (constituting what is called the first sealing) and the chamber (or chambers), delimited by the glass sheets 2, 2', 2,", 2'", etc.
  • PVC polyvinyl chloride
  • spacer frame (frames) 3, 3', 3", etc. capable of containing air or gas 8 or mixtures of gas 8 that give the insulating pane special properties, for example thermal insulation and/or soundproofing.
  • spacer profile 5 which is basically rectangular in cross-section and optionally contains two receptacles on its flanks which are destined for the butyl sealant 6, made of expanded synthetic organic material (for the purposes of non-limiting example, silicone and EPDM) that embeds the hygroscopic material 4 in its mass.
  • the joint between glass sheets 2, 2', 2,", 2'", etc. and spacer frame (frames) 3, 3', 3", etc. or 5, 5', 5", etc. is achieved by means of two levels of sealing, the function of the first 6 being to achieve a hermetic seal and initial bond between these components and affecting the lateral surfaces of the frame and the portions of the adjacent panes, which has already been mentioned (butyl sealant), the function of the second 7 being to achieve definitive cohesion between the components and mechanical strength of the joint between them and affecting the space constituted by the outer surface of the spacer frame 3, 5 and by the faces of the glass sheets up to the rim thereof (see Figures 1A-1F ).
  • the first level of sealing is substituted (in this event the hermetic function is removed) or it can be supplemented by an adhesive, for example acrylic, already spread on the lateral faces of the spacer profile, 6', and covered by a removable protective film (see Figures 1A-1F ).
  • an adhesive for example acrylic
  • the glass sheets 2, 2', 2", etc. utilized in the makeup of the insulating pane 1 can have different shapes as a function of the use thereof; for example the outer sheet (i.e. outer with respect to the building) can be normal or reflective or selective (in order to limit thermal contribution during the summer months) or layered / armored (for anti-intrusion / anti-vandal applications) or layered / tempered (for security applications) or combined (for example reflecting and layered in order to obtain a combination of properties), the inner sheet (i.e.
  • the inner with respect to the building can be normal or low-emission (in order to limit the dispersion of heat during the winter months) or layered / tempered (for security applications) or combined (for example low-emission and layered in order to obtain a combination of properties).
  • the outer glass sheet 2M (and optionally also one or more intermediate sheets) can be bigger than the inner sheet (or sheets) 2'm for the entire extension of the perimeter or only on one side or on some sides (see Figures 1A-1F ).
  • a production line for obtaining the insulating pane 1 product necessitates many types of processes in a cascade, and that in particular it comprises the process of second sealing which is addressed in the present application, not only in situations wherein all the glass sheets 2, 2', 2", etc. are aligned at the perimeter but also in the case where the glass sheets 2M, 2'm, are coupled not aligned but staggered at least on one of the sides, in particular on the lower side 1a.
  • the present invention solves the problem of keeping the peripheral zone, intended for the second sealing, free from all contact with the elements for support and entrainment of the insulating pane 1 (a situation already forming part of the known art but requiring support and entrainment elements that are complex and thus expensive), and this by means of support devices that are simple and therefore economical and adapted to support heavy weights and moreover solve the problem of unloading the insulating pane 1 even if, in particular, it is very big and considerably heavy.
  • process steps listed above can be performed by the corresponding machine, automatically or semi-automatically or, for some operations, manually.
  • EP 1 157 184 B2 (in force), with German priority DE 19909638 of March 5, 1999 , for a device, in the name of Lenhardt Maschinenbau GmbH, relating to the method of transport of the insulating pane 1, in a machine for the automatic sealing of the perimetric rim of the insulating pane, in particular where the glass sheets 2, 2' have different sizes, and whose sides and, consequently, edges are not aligned.
  • the invention is not intended to implement other objectives. Further relevant prior art is disclosed in DE4029669C1 and US6234355B1 .
  • the aim of the present invention is to provide a device that enables the support and transport of the insulating pane 1 before, during and after the sealing of its perimetric rim both if the two or more glass sheets 2, 2', 2,", 2'", etc. are aligned, and if one or more of them is (are) staggered with respect to the remaining ones, and all these cases being feasible by means of only two simple adjustment motions, each one acting independently of the other on one of the two parts of which each conveyor is constituted.
  • an object of the invention is to provide a device that enables the support and transport of insulating panes 1 that are particularly heavy, the possible cases thereof extending, as in the generalized description in the foregoing paragraphs, to include types such as those using glass sheets of high thickness (such as laminated glass or armored glass or thick glass in general) or of large size (up to what is called “jumbo" size, that is to say 6000 mm in length, or even longer, and 3210 mm in height).
  • Another object of the invention is to make it possible to unload the insulating pane 1, once the sealing of its perimetric rim is completed, by means of gripping under its lower horizontal side 1a.
  • insulating pane 1, glass sheet 2, 2', 2,", 2'", etc., spacer frame 3, 3', 3", etc., 5, 5', 5", etc. and further components thereof are identified with single digit numbering.
  • 1 indicates the most common situation (rectangular), with 1' indicating the polygonal shape, 1" the curvilinear shape, and 1'" the mixed shape.
  • the components interfaced with the automatic sealing machine are identified with two-digit numbering.
  • the main components of the new device 100 are identified with three-digit numbers starting from 101 for the part of the conveyor opposite to the operator and 151 for the part of the conveyor on the operator side.
  • the machines belonging to the production line of the insulating pane 1 are identified with four-digit reference numbers.
  • a preferred embodiment of the invention is the one that is described below, and for better comprehension it is recommended to follow the Figures in parallel, in particular Figures 11 to 14 , relating to the inventive concept explained in claim 1.
  • Control of the position of the insulating pane 1, in particular its initial positioning, is essential for the correct operation of the sealing process actuated by the known part of the head 300, through the known nozzle 400 both in the rectangular version and in the contoured version, for the subsequent coordination of the horizontal movements of the insulating pane 1 along the conveyors 100 actuated by at least one movable suction cup belonging to the slider 100' by means of the synchronous motor 102' (not shown since it is known) and the vertical movements of the head 300 which is moved, using the vertical slider 200, by the synchronous motor 202 (not shown since it is known).
  • a sensor detects the position of the margin of the pane and, by means of the logic of the PLC (programmable logic controller), gives the information, which is needed to follow the rectangular perimeter of the insulating pane, respectively to the actuations of the horizontal motion of the insulating pane 1 and the vertical motion of the head 200.
  • PLC programmable logic controller
  • the entire head 300 performs a rotation (of 90° for the rectangular sheet in this first description), by way of the action of the synchronous motor 302 and of the associated known mechanical transmission.
  • this is only a transitory step during which the corresponding feed valve is closed more or less in advance, and opened more or less with delay, possibly pulse-controlled, possibly controlled by modulation of the flow, so as to dose the sealant at the perimetric corner joint.
  • the synchronously actuated horizontal axis H and vertical axis V are also electrically/electronically coordinated for correct filling of the corner, particularly but not exclusively if that corner is connected by means of a radius of curvature and particularly but not exclusively for the finishing of the troweling (not the troweling described earlier on the inner face of the glass sheets 2M, but the troweling on the corner between the continuous sides) which is done by a special spatula working transversely to the plane 901 of the insulating pane 1, adapted to delimit the volume to be filled in proximity to the corner.
  • This coordination is handled by the process computer contained in the electrical/electronic switchboard 11 and it is interfaced with the user by means of the command desk 12 for parameterization of the constants involved in the process.
  • the sealing of the fourth corner 1a/1b and also the corresponding troweling can be done simply by actuating a horizontal movement of the insulating pane 1 up to its separation from the devices for sealing and troweling which in the meantime have retreated transversely with respect to the insulating pane 1 that is to say the plane 901 and the continuation towards the station for unloading the finished product.
  • the rear conveyor 101 is provided with two motions, one, synchronous, actuated (together with the synchronous movement of the pane actuated by the known suction cup slider 100') at the end of the movement of the insulating pane 1 along the horizontal axis H, and one, for adjustment, actuated in order to locate the position of the elements 108 for supporting the glass sheet 2, which are deployed on the endless chain 107 for transport, at the exact height required for the process of sealing the lower perimetric rim 1a of the insulating pane 1.
  • the first motion is actuated by the synchronous motor 102 by means of the kinematic chain: reduction gear 103, transmission 103a, cardan shaft 104, shaft 105, pinion 106, 106a (not shown since it is the idle return pinion, as are the various pinions of which at least one is on a slide for tensioning the chain 107), chain 107;
  • the second motion is actuated by the synchronous motor (the advantage of the synchronous motor is knowing the absolute position so as to simplify the identification of the position of the actuated element) 112 through the kinematic transmission: reduction gear 113, pinion 114, chain 115, pinion 116, ball volute 117, ball screw 118 (it goes without saying that the actuated part can either be the volute or the screw), whereas the vertical guiding of the semi-conveyor 101 is achieved by means of pins 119 and bushings 120.
  • the function of the rear conveyor 101 is to modify the position of the lower edge of the glass sheet 2 and thus, in the case examined first, of the glass sheets 2, 2', 2,", 2'", etc. (together with the activation of the front conveyor 151), which are aligned at the lower horizontal side 1a of the insulating pane 1, it remains in the zero position (or, if this is clearer, the lower stroke limit position).
  • a simplified and more logical variation is that, for the synchronous motion of moving the insulating pane 1 along the horizontal axis H, the chains 107, 157 are actuated by a single motor 102 instead of two motors 102, 152, and by a single reduction gear 103 instead of two reduction gears 103, 153, and in this variation using, after the single motor and single reduction gear, a transmission, the gear transmission 103a which also has the function of driving the two cardan shafts 104 and 154 in its output.
  • the figures show this second situation, which is the most convenient.
  • the conveyor 101 remains in the lower stroke limit position; the conveyor 151 adjusts its position in terms of height only in order to mate with the position of the outer edge of the glass sheet 2' or 2" or 2'" etc. on the operator side, the position of which changes as a function of the total thickness of the insulating pane 1 (see the enlarged details of Figures 11b, 12b and Figure 22 ).
  • the conveyor 101 adjusts its position in height so as to mate with the position of the outer edge of the glass sheet 2 (which in this case, with reference to Figures 1C, 1E, 1F , becomes 2'm) on the side opposite to the operator; the conveyor 151 adjusts its position in height only in order to mate with the position of the outer edge of the glass sheet 2' or 2" or 2'" etc. on the operator side (which in this case, with reference to Figures 1C, 1E, 1F , becomes 2M), the position of which changes as a function of the total thickness of the insulating pane 1 (see enlarged details of Figures 13b and 14b and Figure 23 ).
  • a common characteristic of the two conveyors 101, 151 is that of carrying, on the extrados of the chain 107, 157, a series of inserts 108, 158, deployed at intervals in the direction of the axis H, the upper surface of which forms an acute angle with the sliding plane 901 of the insulating pane 1 (as can be seen in the details in Figures 12b , 13b, 14b and in Figures 22, 23 ).
  • the function of these inserts is to limit contact with the outer edge (outer with respect to the insulating pane 1) of the glass sheets 2, 2', 2,", 2'", etc.
  • Variations which come under the same inventive concept are in any case constituted both by inserts the upper surface of which forms a right angle instead of an acute angle with the sliding plane 901 of the insulating pane 1, and by conveyors wherein the link chains 107, 157 are substituted by transmission belts, preferably of the toothed type, the extradoses of which can form both acute angles with the sliding plane 901 of the insulating pane 1, and right angles.
  • the link chains 107, 157 are substituted by transmission belts, preferably of the toothed type, the extradoses of which can form both acute angles with the sliding plane 901 of the insulating pane 1, and right angles.
  • the problem of dirtying of the inserts 108, 158 by the sealant 7 re-emerges, and most of the known art suffers from this drawback.
  • Figures 5 and 6 for one type of insulating pane 1 and Figures 7 and 8 for another type of insulating pane 1, speak for themselves, but they are still described for identifying a possible variation of Figures 5, 6 , as well as the different use of the conveyors 100 with respect to the sealing operation.
  • a variation for facilitating unloading operations using the means 14 is constituted by the presence of a fulcrum 506 on which the rails 502 are pivoted which, by means of the pneumatic actuator 507, modify the arrangement of the assembly of suction cups 500 from being parallel to the plane 901 of arrangement of the insulating pane 1 to being parallel to the plane 902 of arrangement of the unloading means 14 ( Figure 10 ).
  • a further variation is constituted by the duplication (or multiplication) of the assembly of suction cups 500 in the vertical (pseudo-vertical) direction so as to ensure the insulating pane 1 is stably fixed when its vertical extension is important ( Figure 10 ).
  • both parts 101, 151 of the conveyor 100 are raised or lowered synchronously in the same stroke, since the insulating pane 1, being the one just sealed, is in relation to the lower edge thereof 1a which is to be worked on, simply for obtaining a space for access by the unloading means 14, either at its end parts or at its intermediate part.
  • the intermediate glass sheets 2', 2,", 2'", etc., with the spacer frame of the 3, 3', etc. type undergo a lowering that is slight but still acceptable since the time during which these sheets remain suspended is limited and since this slight lowering is then corrected thanks to the action of the retractable supports of the 551a, 551b, etc. type.
  • one or more intermediate chains 553 of the type of the end chains 107, 157 can be deployed at the one or more intermediate sheets for their support also during the sealing step.
  • Figure 18 is merely for the purposes of example, the actual mechanisms being rather complex since they would in reality interact with positions interfering with those associated with the actuations of the semi-conveyors 101, 151 and therefore they must occupy interlocked regions to prevent interference.
  • the accident prevention aspect is nowadays of primary importance, even a priority over the functionality and productivity of the machine.
  • the invention under discussion is in an advantageous position with respect to the state of the art for the following fundamental reasons: the devices for supporting the insulating pane 1 below the lower horizontal side 1a, although they are provided with the necessary adjustment motions for mating with the edges 1f and 1r of the lower horizontal side 1a (see Figures 22 and 23 ), do not have discontinuities in the direction transversal to the plane 901 and therefore the insulating pane 1 cannot be inserted between the semi-conveyors 101 and 151 that make up the conveyor 100; the load constituted by the insulating pane 1, which is of large size and great thickness and therefore massive, can be easily supported by the conveyor 100 because it has a rigid structure, all overhanging solutions of the shelf type (a situation that is widespread in the known art) being avoided; the monolithic constitution of the semi-conveyors 101, 151 (made possible by the solution re
  • fall prevention guards can be activated in any case, where the activation thereof is based on the checking, performed by the process computer, of the position of the vertical passing through the center of gravity of the insulating pane 1, whether it falls inside the line 1r or not (in fact if it falls inside, and under conditions of play between the line 1f and the supporting elements 158, then the insulating pane 1 would be unstable, crashing to the floor towards the operator).
  • the process computer is capable of determining the position of the center of gravity of the insulating pane 1 since the associated inputs comprise all the information relating to the components of the insulating pane 1, i.e. dimensions and thicknesses of the glass sheets (2, 2', 2", 2'", etc.) or (2M, 2'm, 2"m, 2"'m, etc.) or (2M, 2'M, 2"m, 2'"m, etc.) or (2M, 2'M, 2"M, 2'"m, etc.) or other combinations, and of the spacer frames (3, 3', 3", etc.) or (5, 5', 5", etc.).
  • the present invention is susceptible of numerous variations of embodiment (with respect to what can be gleaned from the pictures, the details of which are evident and self-explanatory) all of which are within the scope of equivalence with the inventive concept, for example the mechanical solutions for the motions for moving and for adjusting the parts 101 and 151 constituting the conveyor 100, the inserts 108, 158 for supporting the insulating pane 1, the means 100' for synchronous horizontal entrainment of the insulating pane 1, the means for synchronous vertical movement of the head 200 containing the extrusion nozzle 400, the means for rotation of the head 300 containing the extrusion nozzle 400, the device for the troweling, etc., the actuation means which can be electrical, electrical/electronic, pneumatic, hydraulic and/or combined, etc., the control means which can be electronic or fluidic and/or combined, etc.
  • a variation of the known part of the invention which however basically resides only in software and thus uses the variations of the known devices for the sealing part, is the variation constituted by the logical combination of the actuations, respectively: horizontal translation of the insulating pane 1 by means of the synchronous motors 102 and 102'; vertical translation of the head 200 by means of the synchronous motor 202; rotation of the head 300 by means of the synchronous motor 302; control of the obturator of the nozzle 400 so as to enable sealing on an insulating pane 1' having a shape other than rectangular in that it is regularly or irregularly polygonal or on an insulating pane 1" having a shape other than rectangular in that it is curvilinear or on an insulating pane 1'" having a shape other than rectangular in that it contains both rectilinear and curvilinear parts.
  • the electric actuators of the four motors, two, 102 and 102', for actuation of the horizontal axis, one, 202, for actuation of the vertical axis; respectively moving the insulating pane 1 and the head 200, and one, 302, for rotation of the head 300 are concatenated by means of an electrical axis (digital control).
  • the constructional details can be substituted with others that are technically equivalent.
  • the materials and the dimensions can be any according to requirements, in particular deriving from the dimensions (length and height) and/or from the shape of the glass sheets 2, 2', 2", etc. constituting the insulating pane 1.
  • an automatic sealing machine 1000 including the innovative devices 100 for the conveyance of the insulating pane 1 and the innovative devices 500 placed at the end of the line for producing the insulating pane 1, and, with respect to the sealing machine, the origin machines (coupling machine and press, optionally filled with gas, etc.) are located to the right; it is easy to imagine a description and associated figures for deployments that are reversed or in some way different, for example including change of the direction of operation of the line.
  • the described sequence of sides to be sealed i.e.: vertical side 1b first, upper horizontal side 1c second, vertical side 1d third, lower horizontal side 1a fourth, can be varied according to the overall requirements of the production line of the insulating pane, of optimization of the cycle time, of alternation of the staggered sides with the non-staggered sides, etc.
  • a different sequence does not involve modifications of the inventive concept, but only implies a modification in the software and possibly a minor intervention in the hardware.
