Definitions
- the present invention relates to a support and guide assembly for conveyor belts of which they comprise a frame that supports the conveyor belts themselves, as well as their own support and guidance mechanisms, such as rollers, guide bearings, etc. .
- support and guidance set has application in the transport and logistics industry, and more particularly it is focused on the transport of luggage between different areas of airport stations; allowing to significantly simplify the maintenance, repair and replacement of all the elements that make up the assembly, minimizing downtimes and saving waiting costs and parts to replace.
- this set of support and guidance for conveyor belts are used in facilities, such as airports or freight logistics centers, in which they are in constant operation, so that the management of their maintenance and repair of breakdowns, must be very agile to reduce the stop time of the respective transport line.
- patents EP0706489, EP are known 0716034, DE 29502064 and DE 19535757 which describe support and guidance mechanisms as described above, which are installed outside the curve, through the outer surface of the frame.

- European patent EP0349830 is already known in which a guide profile for conveyor belts is described, which comprises a protrusion that is conducted between the guide bearings, whose protuberance is provided with a radial appendix provided with a conduit for housing the end of the conveyor belt.
- the profile described in said patent has the disadvantage that it is excessively rigid, which causes vibrations, noise and damage to the conveyor belts.
- the constitution of the band itself since it is obtained from a cross-linking structure of reinforcing wires, which causes a different radial behavior depending on the distribution of said internal structure. These radial oscillations cause, on the different support and guidance elements of the band, cyclic overexertion that causes annoying noise, vibration and fatigue, with the consequent breakdowns and machine stops.
- the patent DE 4412931 is also known in which the perimeter profile comprises an elastic zone which is capable of absorbing a part of the vibrations caused, but still undergoes radial oscillations and additionally said elastic zone, in contact with the bearings, suffers high wear causing a very short life.

- said at least one support and guidance mechanism is coupled to at least one of the surfaces of the substantially planar cantilever structure.
- said bearings are coupled to each support mechanism and guided by an inner side, close to the frame, so that said bearings allow viewing and manipulation from an outer side, away from the frame. Since being coupled to an inner side of the support and guidance mechanism itself, this side being close to the frame, it allows the bearings to be visualized from an outside area and from which the operator is positioned for visual inspection and possible maintenance .
- the lower substructure comprises a plurality of holes intended for coupling support elements of the frame, such support elements may be, for example, support legs on the ground.
- a support and guidance mechanism comprises
- a central fixing base comprising two inclined surfaces converging towards said frame and perpendicular to a perimeter guide profile, where central bearings are coupled to said inclined surfaces in the area opposite the frame, so that they can be viewed and manipulated from the outside, and

- each lateral extension is coupled to the central fixing base, and where each lateral extension comprises a bearing that can also be extracted from the outside, facilitating the assembly, disassembly and visualization of these.
- Each pair of bearings (upper and lower) comprises a certain angle, so that the bearings that form a pair are symmetrical with respect to the conveyor belt that slides through them.
- at least one central fixing base is part of the frame; such that said central base is formed in said frame, and the lateral extensions are directly coupled to it.
- at least one central fixing base is coupled to a rear part of the frame; said central fixing base being therefore an independent element of the frame, being able to be configured of the same material as the lateral extensions.
- the possibility that the support and guidance mechanism is fixed to the frame through at least two fasteners coupled to the central fixing base is contemplated; such fasteners being for example screws, and which can be accessed and manipulated directly from the outside of said support and guiding mechanism.
- the frame to which said, at least one, support and guidance mechanism is attached, or that is part, at least each central fixing base is a frame comprising
- At least one, substantially flat structure is cantilevered with respect to said, at least one, base element, and open on one of its sides where said, at least one, conveyor belt can be introduced / extracted.
- each lateral extension comprises two flat curved elements parallel to each other, joined by a connecting element located at the ends of both curved elements furthest from the central fixing base, so that each outer bearing is coupled on an outer surface to each connecting element that allows its display and manipulation from the outer area opposite the frame.
- each lateral extension is defined by two curved elements joined by a bridge-type joint element; the double 'C geometry can be contemplated, and where the most outstanding technical characteristic is the position of the bearings in the outer zone of the respective joining elements, since being located respectively on an outer surface, they can be manipulated or observed with ease by the operator, without the need to disassemble the support and guidance mechanism.
- each lateral extension is articulated to articulation points located at the ends of both curved elements closest to the central fixing base so that
- Each lateral extension can pivot with respect to the fixing base central and can be extracted at the operator's will, and
- the articulation points are located inside each curved element so that the pair of forces applied on each pair of bearings by the movement of said at least one conveyor belt, causes a moment of forces that ensure the guiding geometry of said conveyor belt without the need for additional fixing elements of each lateral extension.
- both lateral extensions can pivot substantially facilitates the replacement of both the bearings included in them, as well as the possible replacement of the lateral extension itself.
- the position of the articulation points with respect to the position of each pair of bearings results in the closing / service position of the support and guiding mechanism being forced when it is operative, since the sliding of the conveyor belt originates a pair of forces that, aided by the axis of rotation of the lateral extensions, gives rise to a moment of forces in the direction of closing / service of each lateral extension without the need for additional fixing elements of each lateral extension.
- the central space of the structure of each lateral extension comprising two flat curved elements parallel to each other, is open allowing the visualization and manipulation of the bearings from the outside.

- said protuberance comprises a symmetrical through hole with respect to an axis of transverse symmetry of said, at least one, perimeter guidance profile
- said perimeter guidance profile differs from the state of the art since although it comprises an elastic zone that absorbs the radial oscillations and the vibrations caused by the conveyor belt, it comprises a through hole, being able to be of circular configuration, which is capable of deforming and absorbing to a greater degree the aforementioned oscillations / vibrations caused by said conveyor belt, in addition to allowing the decrease of the tensions produced by the flexion during the passage of the perimeter profile guided by the respective rollers (in the changes of sense of movement), thereby increasing its fatigue life, reducing the possibility of breakage and reducing the radii of the movement transmission rollers.
- said perimeter guidance profile is related to a frame comprising
- the zone between said protuberance and the elastic zone comprises grooves that define a free contact space between the bearings and the elastic zone, so that the contact of the bearings with said elastic zone is avoided, ensuring the contact of the cylindrical surface of each bearing with the protuberance.
- Said technical characteristic grants a high degree of safety by having a space that makes contact of the bearings with the elastic zone difficult, which is not very resistant to the contact of the living edges of the bearings themselves; improving both the useful life of said perimeter guidance profile and the guiding performance, and therefore with said grooves the energy consumption of the entire support and guidance assembly is minimized.
- the 'U' shaped extension comprises two branches inclined with respect to each other allowing the perimeter edge of said conveyor belt to be held; making sure that it does not come off and there are no failures in service.
- the elastic zone comprises a section of length equal to or greater than the equivalent average thickness of said section, being, in a preferred embodiment, the length of the stretch of elastic zone between 5 and 30 mm.
- ine ai) of said elastic zone will basically depend on three parameters: the modulus of elasticity € of the material used to obtain the profile, the equivalent average thickness (G ME ) and the length (L) of the section which constitutes the elastic zone.
- the material used for the manufacture of the profile, and the equivalent average thickness (G ME ) of the elastic section will be determined by the stresses of the conveyor belt system.
- the length (L) thereof will be equal to or greater than the equivalent average thickness (G ME ) of said section.
- the protuberance and the U-shaped extension of the guiding perimeter due to the very nature of the material with which it is made, are provided with a certain elasticity, which can absorb a small part of the radial oscillations.
- the absorption capacity thereof is variable and difficult to quantify, since it depends on many circumstances, such as the geometric deformation of the protuberance, as well as the exact point of sewing between the branches and the end of the conveyor belt.
- the incorporation of said elastic section allows to determine and calculate with precision the elastic capacity of absorption of the radial oscillations, since it is not affected by other circumstantial factors.
- the frame for conveyor belts that the invention proposes constitutes an advance in the frames used up to now, and solves in a fully satisfactory manner the problem set forth above, in the line of significantly simplifying maintenance, repair and replacement of all the elements that make up the set, minimizing downtimes and saving waiting costs and parts to replace.
