Description

 TOOL AND REMOTE AUTOMATIC APPLICATION METHOD OF TAPE STRIPS WITH POLYMER REINFORCED WITH FIBERS, WITH DISPENSATION OF

EPOXIC ADHESIVE

5 Technical field of the invention

The invention provides a tool and a method for the automatic application of strips of tape with fiber reinforced polymer, of the type that lack adhesive in the coating of flat surfaces and / or curves of construction elements such as tunnel vaults, arches parabolic, 0 catenaries and other antifunicular characteristic of bridges and many modern constructions.

State of the Art

The present invention relates to techniques for coating elements in constructions with fiber reinforced polymer. These plastics5 (FRP, Fiber-reinforced polymer) are made of a material composed of a matrix of a polymer reinforced with fibers such as fiberglass, carbon fiber, aramid or similar and allow to protect the surfaces in constructions or elements that make up these constructions.

In the state of the art, manual FRP tape applicators are known, or which imply an inefficient, expensive and slow investment of resources: that is, to apply an FRP tape, an operator has both pieces of a smooth, cylindrical wooden bar to the that a cross section has been made that crosses the axis of rotation. The operator holds the end of the roll, commercial of FRP between both pieces, and rolls it around the already complete bar. When cutting the fiber, cutting means are used as industrial scissors, which eventually causes the FRP to degrade, eventually fraying.

The operator spreads epoxy resin on the surface to be treated, helped by a tool such as a brush. Then, the operator supports the bar on this surface and unwind, pressing with the bar itself until the FRP tape is fully adhered, after which it removes the bar, and passes a manual roller, limiting the pressure exerted on the tape to that determined by the surface of the roller and the force of the operator . The previous operations slow down the process considerably since several passes are necessary.

The application procedure using pre-impregnated FRP tape is similarly carried out by an operator. Among its disadvantages are that not only the inconvenience arising from the impregnation of said operator by the resin, but that these tapes should be kept in conditions that prevent the setting of the resin, for example by keeping the tapes pre-impregnated at temperatures above those of setting of the resin.

There is therefore a demand to automate the application of FRP tape minimizing material waste. When this process is automated, an option present in the state of the art comprises mounting the tool on a manipulation means that provides the ability to place and move said applicator, such as a robotic arm or the like (eg Kuka robots to place glass on ceilings: C. Han, Design of a Ceiling Glass Installation Robot, http://www.iaarc.org/external/isarc2007- cd / www / PDF / 2.4_5_076.pdf). Therefore, the greater the mass and dimensions of the tool, the greater the efforts and moments the parts of these handling means will have to support. Furthermore, the manipulation of this tool at a distance implies that the arm operator must be supplied with information to the arm based on the parameters such as the distance to the surface and the coating achieved. To allow the application of adhesive media, the surface must be devoid of contamination, such as those that use water or sand. In addition, the cracks and discontinuities on a surface of some construction elements, present as a result of the different processes after the setting of concrete, movements of heterogeneous lands and the like, make these surfaces present cracks and discontinuities that reduce the adhesion of the coating elements and especially the FRP strips. Therefore, it is desirable that a surface that reduces and more preferably, is lacking, be provided with these fissures and discontinuities. Typically these fissures have thicknesses between 2 and 20 mm, with lengths of up to 1 m, also presenting areas that apparently do not exceed a typical size of up to 10 mm but that hide cavities of much larger size than this. These latter structures are not well treated by those manual applications.

It is possible to minimize these problems by coating the surface, and especially the cracks present in the construction element by applying a means for preparation such as a resin. In the application of those FRP tapes that lack adhesive, it is necessary to dispense said adhesive (generally an epoxy resin or "epoxy" known in the state of the art for each FRP) before dispensing the tape. As the interval between the dispensing of the epoxy resin and the FRP tape increases, chemical adhesion degrades and the resin exposure to contaminants is increased.

A problem present in the state of the art is that related to the optimal application of the tape so that the adhesion is optimal is the corrugation of the tape applied on the surface that does not allow a uniform dispensing of the FRP tape, so that the Mechanical properties of the construction element-coating set are optimal. For this, the tool must be able to place a strip of FRP tape on a layer of a resin (usually epoxy type) previously deposited in a uniform way without applying on the tape tensions that eventually take off said tape, such as when the speed The displacement of the tool on the surface of the construction element is greater than the speed of dispensing of the belt. On the other hand, if the speed of movement of the tool on the surface of the construction element is much lower than that of the tape dispensing, folds are formed in the belt, of way that the coating has corrugations. These corrugations will be the ones that fold back if the weakened surface tries to expand. In addition, these corrugations contain regions (similar to bubbles) of air that degrade adhesion to the surface of the building element. If the tool were not able to provide a strip of tape (by cutting said tape) it would be necessary to cut the tape manually, which slows down the procedure and decreases the efficiency of applying a coating.

In addition, for use in an automated and remote way, the operator needs to receive information about both the position of the tool with respect to the surface of the construction element - as the coating has to dispense the tape following the surface of the construction element ( curvature, accidents, etc.) - as an inspection of the state of the same remotely avoiding impacts of the tool against the surface.

Therefore, it is necessary to provide a tool that allows the application of a coating on the surfaces of construction elements with FRP tape, comprising the dispensing of strips of FRP tape, embedded in an epoxy resin, which does not present undue corrugations in the coating, and without causing tensions that take off already glued tape, thus achieving a coated surface where the properties of the FRP tape and the surface of the structure are combined, thereby significantly improving the mechanical properties (eg elasticity) of the coating of said structure.

Description of the invention These and other problems are solved in the present invention by means of a tool that allows the preparation of the surface of a construction element for the dispensing, embedding and cutting of a strip of FRP of the non-pre-impregnated type of adhesive, of automatically and remotely according to independent claim 1. In addition, a method according to independent claim 14 for the remote and automated application of FRP tapes. Other aspects of the invention and particularly advantageous embodiments thereof are defined in the dependent claims.

In a first aspect, a tool can be connected to a manipulation means such as a robotic arm, made of aluminum, Nylon to minimize the stresses and moments exerted on the manipulation means (e.g. the joints of a robotic arm). This tool comprises a structure or frame for the application of this FRP tape. Among these elements there are storage means, such as a FRP tape roller, which supply a tape to a FRP tape dispensing means, such as guide rollers, which in turn comprises a set of cutting elements to provide strips. of FRP tape. It also comprises a driving means, preferably comprising a driving roller, mechanically connected by means of transmission to the FRP tape dispensing means as well as a compression means for embedding said tape in an adhesive, so that advantageously the movement provided by the handling means, moving the tool on the surface defining an application direction and a direction of travel, provides power transmitted to a FRP tape dispensing means adjusted so that the FRP tape dispensing speed is substantially similar to that of tool offset

The tool is preferably inscribed in a parallelepiped with dimensions of a width between 0.15 and 1.5 m, a length of 0.15 m and a height of 0.10 m. These dimensions allow the tool to also have greater maneuverability to allow automatic coating over a wide range of radii of curvature, especially those present in tunnel vaults. The tool does not present any autonomous driving means as motors for reduce the weight of it to a minimum. On the contrary, the drive means that guides the belt and allows to follow the curvature of the surface of the construction element and take advantage of the load provided by the handling means. For this purpose, it has a traction surface adapted to adhere to the surface of the construction element. Depending on the surface on which the driving means is moved, it is possible to select advantageously those materials for manufacturing the traction surface looking for an improvement in adhesion which allows to obtain better results in the application of the tape. Advantageously, the tool incorporates means for detachably attaching different traction surfaces to the driving means, so that different types of materials of the surfaces of the construction elements are capable of coating for the same characteristics of the manipulative means.

The tool uses transmission elements that allow a substantially 1: 1 ratio between the speed of dispensing of the belt and the advance of the tool as a gear set or a belt-pulley assembly, of dimensions adapted to compensate for the relative dimensions of the drive and dispensing rollers. Preferably by means of a set of pulleys and gears that connect the roller of the driving means or with the dispensing means. Particularly it lies between the roller of the driving medium and the roller of the dispensing medium compensated with a 1: 1 ratio.

The cooperation between the handling means, the driving means and the transmission means makes the speed of dispensing of the FRP belt substantially equal to the speed with which the tool travels on the surface to be coated of the construction element, avoiding tensions in the FRP tape and that when dispensing the FRP tape on the surface of the construction element it presents folds and gives rise to corrugations. Furthermore, the set of cutting elements of the dispensing means adapted to guide the belt from the storage medium, preferably by means of a set of rollers of the set of cutting or guide elements, which is in contact with the FRP tape and prevents its recoil so that it provides FRP tape after cutting the tape, which allows to provide strips of FRP tape automatically.

In addition, the tool has a compression means that allows the tape to be soaked and soaked with the epoxy resin that has previously spread over the surface. For this purpose, it has a compression means that, after dispensing the tape on the surface of the construction element, exerts a pressure, embedding the FRP tape in the adhesive medium, which permeates the fibers of the FRP tape. The tool has means adapted to channel a jet of a gas towards the surface, preferably, taking as a reference the direction of travel, oriented towards a region prior to the drive roller, preferably being pressurized air to perform surface cleaning processes of the element construction which simplifies the cleaning system compared to those that, such as sand or hydrodernolition, involve the presence of valves and deposits, causing fewer incidents with passers-by because it avoids the presence of liquids.

It also incorporates means for dispensing adhesives and resins for coating cracks and discontinuities on the surface to be coated. For this there is an area adapted to removably accommodate a resin dispenser in the tool that allows both to fill cracks, as well as to provide an adhesive in which to embed the strip of FRP tape. The resin dispenser is capable of being actuated to dispense resin, preferably remotely, it is oriented to dispense the epoxy resin in a posterior region the driving roller and prior to the dispensing roller in the direction of travel, thus allowing a dispensing of the epoxy prior to the dispensing of the FRP tape.

In addition, both to automate and to allow control of the tool it advantageously incorporates distance control means to the surface of the construction element with information on both the position of the tool relative to the surface of the construction element.

It also advantageously incorporates sensors such as telematic means for determining the distance to the surface of the tool such as optoelectronic means that allow the inspection of the state of the surface of the construction element remotely.

In a second aspect, a method for remote automatic coating by strip of FRP tapes is provided, comprising using the tool described in the first inventive aspect remotely, by means of manipulation, on the surface), curved or flat, of construction elements such as tunnel vaults according to claim 13 comprising a) providing a tool for the application of FRP tape as cited in the first inventive aspect b) moving the tool on the surface of the construction element c) driving the dispensing of resin of the resin dispensing medium d) remotely actuate the cutting means In an embodiment, the fissures of the surface of the construction element are coated in an earlier stage with an epoxy resin. This makes it possible to improve the adhesion of the FRP tape, and completed in another embodiment variant by cleaning the surface of the construction element by means of cleaning means and particularly by compressed air, which results in a better adhesion of the FRP tape.
