    [0002] Deflection system for transport systems based on rafle-guided vehicles
    [0003]
    [0004] The present invention relates to a diversion system for transport systems based on rails guided vehicles, in particular in self-propelled vehicles.
    [0005]
    [0006] Background of the invention
    [0007]
    [0008] In the field of maintenance there are different ways to move the loads inside the warehouse. One of the several systems are the so-called floor electrovias or vehicles guided by rafles. These systems are responsible for moving loads between different areas of the facilities on vehicles, either from one point to another of the warehouse or in connection with production areas to the warehouse.
    [0009]
    [0010] In the vehicle systems guided by rafles the vehicles move along rails, the circuit can be a closed loop without alternative ways or you can use rotary type bypass systems.
    [0011]
    [0012] When diversion systems are used, the vehicle must stop when approaching the detour, the diversion system turns to orientate it as desired, and once correctly oriented, the vehicle moves again. This implies a significant loss of time in each cycle.
    [0013]
    [0014] These deflection systems usually comprise a rotating frame provided with rails, and the position of the rotating frame depends on the desired trajectory of the vehicle.
    [0015]
    [0016] An example of this type of deflection systems is described in document US 2010147183 A1, which refers to a deflection system provided with two straight rails and two curved rails mounted on a rotating frame, which make it possible to define a plurality of positions.
    [0017]
    [0018] Therefore, an object of the present invention is to provide a system of diversion for transport systems based on rails guided vehicles that is as simple and economical as possible, which avoids the arrest of vehicles when approaching the system of diversion when this changes its position, and that allows the free passage of the vehicle, without the rafles hinder the passage of the wheels of the vehicle.
    [0019]
    [0020] Description of the invention
    [0021]
    [0022] With the deviation system of the invention, the aforementioned drawbacks are solved, presenting other advantages that will be described below.
    [0023]
    [0024] The detour system for transport systems based on rails-guided vehicles according to the present invention comprises a frame provided with a straight rail and a curved rail integral with said frame, said frame being rotatable about an axis of rotation, and it is characterized in that the deflection system has only a straight rail and a curved rail, said rotation axis being arranged offset with respect to said straight rail and said curved rail.
    [0025]
    [0026] Advantageously, said axis of rotation is arranged between the straight rail and the curved rail and, according to a preferred embodiment, said axis of rotation is arranged equidistantly to the respective midpoints of the straight rail and the curved rail.
    [0027]
    [0028] The deflection system for transport systems based on rails-guided vehicles according to the present invention also advantageously comprises a motor that drives the rotary frame, said motor being mounted on the rotating frame.
    [0029]
    [0030] According to a preferred embodiment, the frame is rectangular in plan which defines first and second long sides and first and second short sides, the straight raffl being arranged next to the first long side and the curved rafl being placed passing through the defined vertices on the second long side and the first and second short sides, and the motor is preferably mounted on the second long side.
    [0031]
    [0032] Advantageously, said frame comprises a plurality of wheels, and said wheels are preferably oriented towards the axis of rotation, and arranged on the long sides of the frame.
    [0033]
    [0034] Said frame is preferably rotatable between a plurality of positions, said positions being offset 45 ° from each other. In particular, it can be placed in a first position, in which the straight raffl is used, in a second position, displaced 45 ° respect to the first position in one direction, and in a third position, displaced 45 ° with respect to the first position in the opposite direction in which the curved rail is used.
    [0035]
    [0036] With the system of deviation for transport systems based on rails-guided vehicles according to the present invention, at least the following advantages are achieved:
    [0037]
    [0038] - Prevents the vehicle used in the transportation system from stopping before reaching the deviation system, being able to make a continuous movement, with the consequent saving of time;
    [0039] - the fact of using a single straight rail and a single curved rafl simplifies the system and makes its cost low;
    [0040] - the disposition of the axis of rotation displaced with respect to the rafles allows that the rotation of the frame does not affect the passage of the vehicle, in particular of its wheels; Y
    [0041] - the colocation of the motor mounted on the rotating frame itself also allows that the rotation of the frame does not affect the passage of the vehicle.
    [0042]
    [0043] Brief description of the drawings
    [0044]
    [0045] To better understand what has been exposed, some drawings are accompanied in which, schematically and only by way of non-limiting example, a practical case of realization is represented.

    [0052]
    [0053] Description of a preferred embodiment
    [0054]
    [0055] As shown in the figures, the deflection system for conveyor systems based on raffle-guided vents according to the present invention comprises a frame 1 provided with a single straight rail 2 and a single curved rafl 3 which are integral in rotation with said frame, so that they rotate when the frame 1 rotates.
    [0056]
    [0057] Said frame 1 is rotatable about a rotational axis 4 which, in its use position, is substantially vertical, since the frame rests on the ground, for example, of a warehouse.
    [0058]
    [0059] Said rotational axis 4 is arranged offset relative to said rails, in particular, it is arranged between said straight rail 2 and said curved rail 3, more specifically at the same distance from both rails 2, 3 and aligned with the midpoints of the straight rail. 2 and curved rail 3, as can be seen in the figures.
    [0060]
    [0061] The frame 1, according to the embodiment shown, is rectangular in plan, although it could be of any suitable shape, and defines a long first side 11, a long second side 13 and two short sides 12.
    [0062]
    [0063] According to this embodiment, the straight rail 2 is arranged next to the first long side 11, while the curved rail 3 is arranged so that it passes through the vertices defined by the second long side 13 and the short sides 12 of the frame 1.
    [0064]
    [0065] For its rotation, the frame 1 comprises a motor 5 mounted on it, which rotates with the frame 1 when it is integral with it. Said motor 5, according to the embodiment shown, is mounted on the second long side 13 of the frame 1.
    [0066]
    [0067] The frame 1 also comprises a plurality of wheels 6 for its rotation. These wheels are arranged in the lengths 11, 13 of the frame, according to the embodiment shown.
    [0068]
    [0069] In particular, the wheels 6 are grouped in pairs and are aligned with the axis of rotation 4 of the frame 1, that is to say, the extension of the axis of rotation of each pair of wheels 6 is crossed with the axis of rotation 4 of the frame 1, the wheel assembly 6 defends a circular path when said frame 1 rotates.
    [0070]
    [0071] It should be noted that the deflection system according to the present invention is specially designed for use with ramp-guided self-propelled vehicles (not shown in the figures), which comprise four wheels, two of which are guided by the rails and the others two move along the ground. This type of vehicle it is not described in detail because it is not part of the present invention and because they are known to those skilled in the art.
    [0072]
    [0073] The deflection system according to the present invention can be placed in a plurality of positions, in particular, it can be placed in the three positions shown in Figures 1 to 3.
    [0074]
    [0075] In figure 1 a first position of the deviation system is shown, and in this position the straight rail 2 is used for the guidance of the corresponding vehicle. As shown in this figure, the straight rail 2 will be aligned and connecting with first rails 20 which are fixed in the transport installation.
    [0076]
    [0077] In figure 2 a second position of the deflection system is shown, and in this position the curved rail 3 is used for guiding the corresponding vehicle. In this position, the curved rail 3 connects one of said first fixed rails 20 with a second fixed rail 21 of the installation. With respect to the first position shown in figure 1, this second position has moved 45 ° in a clockwise direction.
    [0078]
    [0079] In figure 3 a third position of the deflection system is shown, and in this position the curved rafl 3 is used for guiding the corresponding vehicle. In this position, the curved rafl 3 connects one of said first fixed rails 20 with another second rafl 21 also fixed to the installation. With respect to the first position shown in figure 1, this second position has moved 45 ° counterclockwise.
    [0080]
    [0081] Obviously, the deviation system also includes computerized control means to control the trajectory that the vehicles must describe, without being necessary to stop before the change of trajectory by means of the deviation system according to the present invention.
    [0082]
    [0083] Although reference has been made to a specific embodiment of the invention, it is obvious to a person skilled in the art that the system of deviation described is susceptible of numerous variations and modifications, and that all the mentioned details can be substituted by other technically equivalents, without departing from the scope of protection defined by the appended claims.
