Description

glass handling system

[0001] The present invention relates to systems linked to the handling of glazing, in particular for glazing intended for the transport sector: automobiles, buses, trucks or for glazing intended for buildings. Prior art

[0002] In many fields, the glazing used is handled on numerous occasions, such as during assembly, installation, replacement, or maintenance. Thus, the glazing is handled before being installed in its host structure or after being removed from its host structure for replacement or maintenance (repair).

[0003] In these cases, the glazing is carried by an operator and placed on a docking station or handling system. The glazing in question is glazing used in the transport or construction sectors and these glazings have large dimensions and therefore a significant weight.

[0004] A known handling system consists of a table composed of two metal profiles in the shape of a rectangular bridge arch and articulated along an axis passing through the middle of their vertical uprights. Seen from the side, these articulated uprights form an "X" in the deployed position. The deployed position is maintained by a chain stretched between the two horizontal sections or above the articulation of the lateral uprights. The upper part of the table, composed of two parallel bars, is intended to receive the glazing or glass panel. The upper part is systematically covered with soft foam sleeves which prevent scratching or breaking the windshield in the event of accidental contact with the metal structure of the table. These sleeves also have a good grip on the windshield, which allows the glazing to be kept in a stable position during various preparation operations (cleaning, application of the bead of glue, etc.).

[0005] However, automotive and building glazing tends to have a long radius of curvature. Such a radius of curvature requires the glazing to be correctly positioned on the handling system, otherwise the glazing may roll or tilt during a maintenance operation such as installing an adhesive or a seal. This tilting makes the operation uncomfortable. However, incorrect orientation of the glazing on the two parallel bars at the top or poor centering can cause such tilting.

[0006] The disadvantage of these handling tables is that they are not ergonomic. Indeed, the installation of the glass panel or glazing requires the operator to carry the glazing into place, centering it as much as possible while avoiding damage to the glazing by scratches or breakage.

[0007] However, the presence of foam sleeves to prevent scratches does not allow the glazing to slide, so the operator must handle the glazing to center it. This manipulation consists of projecting forward with the glazing to place it as centered as possible or placing the glazing on the edge of the table and then making small rotational movements to bring the glazing closer to the center. This operation can be repeated if the glazing must undergo an operation on each of these faces.

[0008] It is known to have tables whose sleeves are replaced by four suction cups supporting the glazing. However, the suction cups present significant friction which requires the use of a method requiring the operator to project himself or make small rotational movements.

[0009] These difficulties also arise when turning over. With parallel bars as the upper part, a high friction prevents the glass sheet from sliding on its edge and therefore forces the operator to carry the glazing. With the four support points in the form of suction cups, carrying the glazing is mandatory.

[0010] There is therefore a need for a glazing handling system that allows for simpler and less restrictive glazing installation and turning for the operator.

[0011] The present invention seeks to overcome the drawbacks of the prior art by proposing a glazing handling system which allows easy installation, centering and easy turning.

[0012] To this end, the present invention relates to a glazing handling system 1 comprising a support structure carrying a support base, characterized in that the support base comprises movement means to allow, by rotation, the glazing to be moved when the latter is laid flat, said movement means have a resistive force whose value allows the rotation of the movement means when a translation force is applied to the glazing greater in intensity than the resistive force, said resistive force being furthermore sufficiently high to hold the glazing sufficiently stable on the movement means when the only stress applied to the glazing is its own weight.

[0013] According to one example, the means of movement have an adjustable rotational resistance force whose value varies between 5 and 500 Newtons.

[0014] According to one example, the means of movement have a constant rotational resistance force whose value is between 5 and 500 newtons, preferably between 10 and 200 Newtons.

[0015] According to one example, the means of movement are provided with at least one stopping system for blocking said means of movement.

[0016] In one example, the resistive force of the means of movement comes from a pair of materials rubbing against each other.

[0017] According to one example, the resistive force of the means of movement comes from a viscous friction system mechanically connected to the means of movement

[0018] According to one example, the moving means comprise at least one roller, at least one wheel or at least one ball or a combination thereof to obtain stable support for the glazing.

[0019] In one example, the moving means comprise two rollers.

[0020] According to one example, the moving means comprise four wheels, preferably arranged at the four corners of a parallelepiped.

[0021] According to one example, the support base further comprises sliding means.

[0022] According to one example, the sliding means comprise at least one plate or at least one rail.

[0023] According to one example, the sliding means are arranged between the moving means and such that the plane passing through the vertices of the moving means overhangs the plane passing through the vertices of the sliding means.

[0024] According to one example, it further comprises support means in the form of at least one support bar, said support bar extending from the support base.

[0025] In one example, the bar extends substantially horizontally.

[0026] In one example, the bar is linear or curved.

[0027] According to one example, the support base is mounted to be movable in translation relative to the support structure by means of translation elements.

[0028] In one example, the support structure comprises a frame made of tubes or profiles.

[0029] According to one example, the moving means and the sliding means are mounted on plates, said plates being fixed directly or indirectly to the support base.

[0030] In one example, each plate carries a rail and two wheels, the rail being arranged between the two wheels, essentially along the same line.

[0031] The invention further relates to a method of operating the handling system during a maintenance operation on at least one face of a glazing unit according to the invention, said method comprising the following steps:Providing the glazing unit to be treated and providing the handling system;Place the glazing unit on the movement means on the surface opposite the surface to be treated;Moving the glazing unit to give it the desired position by applying to said glazing unit a translation force greater in intensity than the resistive force of the movement means;Carrying out said maintenance operation on the face of the glazing unit.

[0032] According to one example, the maintenance operation of a glazing is also carried out on the other side of the glazing, said method then comprising a turning step consisting of:

[0033] - provide the glazing,

[0034] - lift the glazing from the handling system and then turn it over;

[0035] - place the glazing on the means of movement on the surface opposite the surface to be treated,

[0036] said method further comprising the following steps:Moving the glazing to give it the desired position by applying to said glazing a translation force greater in intensity than the resistive force of the moving meansCarrying out said maintenance operation on the face of the glazing.

[0037] According to one example, said handling system comprises sliding means, said turning step consisting of:

[0038] - Move the glazing in translation using the moving means and continue by sliding the glazing on the sliding means in order to be able to take hold of the glazing;

[0039] - Lift the glazing from the handling system and turn it over;

[0040] - Place the glazing on its edge on the sliding means;

[0041] - Slide the glazing on the sliding means until the surface opposite the surface to be treated is placed on the moving means.

[0042] According to one example, the movement means are provided with a stop system, said stop system being disengaged to allow the glazing to be moved into the desired position and then engaged once the position of the glazing has been reached. Description of figures

[0052] The glazing handling system 1 represents a glazing handling system according to the invention. This glazing handling system allows an operator to work on glazing 100 such as those used in the transport sector or those used in the construction sector. These glazings may be flat or have a curve.

[0053] The glazing handling system comprises a support structure 10 carrying a support base 20.

[0054] In a first embodiment, the support base 20 comprises movement means 22. The movement means are used to support the glazing and to allow the glazing to be moved when it is laid flat.

[0055] In a first embodiment, the displacement means 22 comprise two rollers 220 mounted parallel as seen in Figures 1 and 2. These two rollers are arranged to be spaced apart from each other.

[0056] In a second embodiment visible in the, the movement means 22 comprise wheels 222. The movement means comprise at least three wheels arranged to form a triangle. This arrangement makes it possible to support the glazing.

[0057] In a variant of this second embodiment, the displacement means 22 are balls. This variant advantageously allows freer displacement, not limited to a single direction.

[0058] Of course, it is possible to combine the embodiments with displacement means comprising a roller 220 and at least one wheel 222 as visible in the figure. It is then understood that at least two support points are necessary, three in the case of the exclusive presence of wheels.

[0059] The displacement means 22 are clever in that they present a resistive force during their rotation. The level of resistive force physically derives from a coefficient of rotational friction which is defined as being representative of the friction, the friction, which exists between said rotational displacement means and the support on which they are mounted. It is then understood that the coefficient of rotational friction in question is that present between the wheel or roller and the shaft which carries this wheel or roller (or between the shaft which carries it and the support plates in the case where the axis of the wheel or roller is also driven in rotation). This coefficient of rotational friction is also that which is present between the ball and its support.

[0060] The resistive force is the result of a compromise. First, it must be low enough to allow the rotation of the moving means. Second, it must be high enough to hold the glazing stable enough on the moving means so that the operator can carry out preparation operations on the glazing (cleaning, fixing a peripheral seal, applying glue, etc.). This resistive force is then constant or adjustable.

[0061] This resistive force of the means of movement during the displacement phases comes from a pair of materials rubbing against each other, the adjustment of the resistive force being done by the pressure applied between these materials.

[0062] Alternatively, the resistive force of the means of movement during the movement phases comes from a viscous friction system mechanically connected to the means of movement

[0063] Alternatively, this resistive force is obtained by mechanical action on a pad which brakes the means of movement. An adjustment of the resistive force is then made by pressure, more or less strong, of the pad on the means of movement. This allows to have an adjustable resistive force allowing to obtain different compromises between the thrust force exerted on the glazing during the phases of movement of the glazing and outside the phases of movement of the glazing.

[0064] The movement means are activated indirectly by the operator who simply pushes or pulls the glazing. For the rotation of the movement means to be effective, it is necessary that the surface of these movement means has a good grip with the surface of the glass (the coefficient of friction between the surface of the movement means and the glass is then high) such that the translational movement of the glazing causes the rotation of the wheels, rollers or balls forming the movement means. The translational movement of the glazing is obtained by applying a force, in translation, to said glazing.

[0065] It is important that the translational movement of the glazing is carried out by rolling without sliding on the moving means. Indeed, such sliding could cause scratches on the surface of the glazing if, for example, the surface of the moving means is polluted by hard dust such as mineral particles for example. It is therefore important to be able to adapt the nature of the external coating of the moving means to the pushing or pulling force exerted on the glazing by the operator in order to always have sufficient grip of the external surface of the moving means on the surface of the glass.

[0066] Good grip of the means of movement is the result of a surface friction coefficient. This coefficient of friction is the one present between the surface of the means of movement (wheels, balls, rollers, etc.) and the surface of the glazing. This surface friction coefficient can have an impact. Indeed, if this surface friction coefficient is too low, it is possible that the glazing slides on the means of movement without causing them to rotate. This possibility arises especially if the resistive force is high. This lack of rotation can also occur if, on the contrary, the surface friction coefficient is too low. This high surface friction coefficient, allowing good grip of the surface of the glazing, is obtained by a rubber or elastomer type material.

[0067] The surface friction coefficient is chosen according to the needs. For example, in the case of a friction coefficient provided by a tread, the latter is interchangeable.

[0068] In one variant, the movement means 22 comprise at least one stopping system. This stopping system is a system such as a mechanical brake allowing the rotation of the rollers or wheels to be completely blocked. This then allows said movement means to act as simple skates. This stopping system can thus equip at least one of the wheels or balls or at least one of the rollers. The stopping system can also equip all of the movement means 22.

[0069] The glazing handling system according to the invention operates as follows. The operator, who carries the glazing or glass panel with his bare hands or via suction cup gripping systems, places the glazing or glass panel flat on the support base. The good grip that exists between the surface of the moving means and the surface of the glass then makes it possible to move the glazing in at least one direction by applying a translational force provided that this translational force is greater in intensity than the resistive force or the rotational friction coefficient of the moving means. This allows the operator to place the glazing on the support base so that the glazing is cantilevered and therefore puts less strain on his back. Once the glazing is installed, the operator can slide the glazing to center it. The rotational friction coefficient ensures that, once the glazing is in its position, the glazing does not move easily.

[0070] The operator can then begin operations on the face of the visible glazing. The resistive force of the moving means allows the glazing to withstand forces and shocks from the operator during operations carried out on the glazing without said glazing moving. It is then understood that the resistive force has a value such that the momentary application of a translation force lower than a certain threshold, for example 10 Newtons (equivalent to the weight of a mass of 1 kg) does not cause significant movement of the glazing while the application of a translation force higher than this threshold, i.e. 10 Newtons in our example, causes a movement of the glazing. In the case of a constant resistive force, the moving means have a resistive force whose value is between 5 and 500 Newtons, preferably between 10 and 200 Newtons.

[0071] In the case of an adjustable resistive force, the interest is to have the possibility of adjusting the coefficient of rotational friction in order to be able to immobilize the glazing during different types of maintenance operations without having to activate the stopping system. Thus, in the case of maintenance operations requiring significant forces to be applied to the glazing, the coefficient of rotational friction will be set to a high threshold, typically 50 or 100 Newtons or higher such as 200 Newton. For particular operations such as the detachment of components bonded to the surface of the glazing using a knife requiring the application of significant and prolonged forces to the glazing, values ​​of up to 500 Newton may be necessary. Thus, the resistive force has a value that varies between 5 and 500 Newton.

[0072] Adjusting the resistive force also allows you to adapt to the glazing. Depending on the size of the glazing, it can be more or less heavy. However, heavy glazing places more stress on the moving means and therefore becomes less easily movable. By adjusting the resistive force, this additional constraint is compensated. In addition, an adjustable resistive force optionally allows you to do without a stop system.

[0073] Thus, whether the resistive force is constant or adjustable, it never prevents the movement of the glazing, which is possible as long as the user applies sufficient force to the glazing. It is the stopping system that allows the movement of the glazing to be completely stopped.

[0074] If the glass requires work on its other side, the operator must turn the glass over. The operator then takes the glass, turns it over, and places it on the moving equipment.

[0075] In one variant, the stop system is present, which is then engaged or disengaged as needed. It is understood that the stop system is disengaged to allow the glazing to be moved into the desired position and then engaged once the glazing position has been found. The operator can then begin operations on the visible face of the glazing.

[0076] In a second embodiment, the support base 20 further comprises sliding means 24.

[0077] In a first embodiment visible in the figure, the sliding means comprise a plate 240. This plate is flat or curved.

[0078] In a second embodiment visible in figure 6, the sliding means comprise at least one rail 242. This rail is straight or curved.

[0079] The sliding means 24 are positioned relative to the moving means 22 such that the sliding means 24 are positioned in the space between the moving means.

[0080] We then understand that the wheels 222 or rollers 220 frame the plate or the rails.

[0081] Preferably, the rollers 220 are associated with sliding means in the form of a plate 240 and the wheels 222 are associated with sliding means in the form of a rail 242 but these associations are not limiting and sliding means in the form of a plate can be associated with wheels. Likewise, it is possible to have sliding means in the form of a plate associated with a roller and a wheel.

[0082] The moving means such as rollers, wheels or balls are positioned relative to the sliding means, plate or rails, to be raised. It is then understood that when the glazing is placed on the moving means, it does not come into contact with the sliding means. Thus, the plane passing through the top of the moving means is higher than the plane passing through the top of the sliding means, there is therefore a gap between these planes.

[0083] The presence of sliding means makes it possible to improve the handling of the glazing, particularly when said glazing requires operations on its other side. The operating method and use of the handling system is thus as follows.

[0084] The installation of the glazing consists of: Laying the glazing on its edge on the sliding means; Sliding the glazing on the sliding means until the surface opposite the surface to be treated is placed on the moving means; Moving the glazing to give it the desired position by applying to the glazing a translation force greater in intensity than the resistive force of the moving means; Carrying out said maintenance operation on the visible face of the glazing.

[0085] If the glazing needs to be turned over, the following steps are carried out:Move the glazing in translation using the moving means and continue by sliding the glazing on the sliding means in order to be able to take hold of the glazing;Lift the glazing from the handling system as seen in the and turn it over;Place the glazing on its edge on the sliding means;Slide the glazing on the sliding means until the surface opposite the surface to be treated is placed on the moving meansMove the glazing to give it the desired position by applying to the glazing a translation force greater in intensity than the resistive force of the moving means;Carry out said maintenance operation on the visible face of the glazing.

[0086] Once the maintenance is completed, the following steps are taken:

[0087] Move the glazing in translation

[0088] Preferably, the spacing between the top of the displacement means 22 and the sliding means 24 is such that when the glazing slides on said sliding means, contact with the displacement means causes the glazing to transition smoothly and smoothly from the sliding means to said displacement means so that the positioning of the glazing continues. If the spacing is too great, the displacement means act as a stop preventing the glazing from sliding further. The same is true if the displacement means are too high relative to the sliding means. In a variant of the embodiments visible in the, the handling system comprises support means 30 in the form of at least one support bar 32. This support bar extends from the support structure or from the support base. This support bar is used to allow the glazing to rest on said bar on its edge.Preferably, the handling system comprises bars arranged in pairs. This provides two support points for the glazing.

[0089] The support bar(s) 32 extend substantially horizontally, i.e. horizontally or at an angle so as to be slightly raised. This ensures that the glazing is held in place. The bars may be straight or curved, smooth or notched. They are preferably coated with a material that adheres well to the edge of the glazing in order to minimize the risk of the glazing slipping and falling.

[0090] Preferably, the handling system comprises two pairs of holding bars 32, the pairs being arranged on opposite sides, preferably on either side of the moving means.

[0091] This variant optionally includes buffer means 34. These buffer means 34 are arranged to cooperate with the retaining bars 32. These buffer means include washers made of flexible material having good grip with the surface of the glass, such as rubber. These buffer means allow, when the glazing is placed on its edge on the bars, said glazing to rest on the buffer means. This then prevents damage to the glazing.

[0092] These bars are then used during the operation of the handling system in multiple phases. For example, these bars can be used before placing the glazing on the handling system so that the operator can potentially catch their breath. In another example, the bars are used when turning the glazing.

[0093] The support structure can take different forms.

[0094] In a first form, the support structure 10 consists of a base plate 12 supported by at least one foot 14 as seen in the figure. This foot is in the form of a peripheral wall. On the base plate, the movement means and the guide means (if present) are arranged.

[0095] In a variation of this first form, the vertical peripheral wall is replaced by four feet arranged at the corner of the base plate as seen in. Each foot is in the form of a vertical post. This variation frees up space under the base plate.

[0096] In another variation of this first form, the legs are arranged in the form of a pair of feet. The feet of this pair are arranged on opposite sides. Each foot is in the form of a central pillar fixed at one end to the base plate and comprising at its second end support points on which the manipulation system rests. Each foot preferably comprises two support points.

[0097] Alternatively, each leg includes an H-shaped structure. This structure thus has two points fixed to the base plate and two points serving as support points.

[0098] In a second form, the support structure 10 is in the form of a frame 16 carrying the support base 20 as seen in the figure. The frame is composed of tubes 161, metal profiles for example in the form of two H-shaped trellises connected by at least one central beam.

[0099] The upper part of the H-shaped trellis is capable of supporting the support base, i.e. the movement means and the sliding means, if present. These sliding means and these movement means are carried by at least one plate, fixed to the H-shaped trellis.

[0100] In the case of moving means comprising wheels, two plates are used for their mounting. In the case where the moving means comprise four wheels, two plates are used, each plate carrying two wheels. The wheels of each plate are placed essentially on the same line. Each plate is mounted on an H-shaped trellis as seen in the. If sliding means are provided, such as rails, these rails are carried by the plates. These plates can be fixed to the support base but the plates can also be fixed to the support structure and thus form the support base. In this case, the plates are likely to also carry the support means 30.

[0101] In a variant of the second form, the support structure is designed to be foldable. In this variant, the central beam is designed to fold. The beam then comprises a hinge and locking means. When the locking means are unlocked, the central beam can fold. This folding of the central beam allows the two H-shaped trusses to come together.

[0102] In one variant, the support base is movable relative to the support structure. The support base is mounted on translation elements such as jacks, i.e. mechanical or electromechanical elements allowing the translation of two elements relative to each other. This height adjustment makes it possible to adjust the height of the support base to the size of the operator in order to reduce the effort required. In this variant of the height adjustment, the support means 30 may be arranged not on the support structure but on the support base. This makes it possible to adjust, at the same time, the height of the support means to have support means 30 whose height is always ergonomic.

[0103] Of course, the present invention is not limited to the illustrated example but is susceptible to various variants and modifications which will appear to those skilled in the art.

[0104] Indeed, it is possible that sliding means in the form of rails or plates are used to directly carry the means of movement in the form of wheels.
