    CABLE STRETCHING MACHINE DESCRIPTION 5 Field of the invention
    The present invention relates to a cable docking machine, specially designed for mounting on ship decks, for cable stowage, especially for L.A.R.S.
    The machine of the invention is of the type comprising a reel, on which the winding of the cable is carried out, and guiding means of said cable on the reel, during the winding operation. 15 Background of the invention
    At present, cable dock machines comprise a cable guide mechanism consisting of two parallel free-spin rollers, generally perpendicular to the axis of the reel, which are mounted on a support close to the reel 20 and which can be moved in a direction parallel to the axis. of said reel. This mechanism is simple and effective for winding normal cables. However, when stowing special cables that require a certain care, such as umbilicals with optical fiber inside, they are very poor, since this configuration makes it impossible to meet the minimum requirements of curvature of the
    25 cable (relation between the diameter of the cable and the diameter of the elements through which it circulates), and there are also frictions in many points of the stowage.
    From US6443431 a stowage system is known which, unlike the conventional system described above, reduces friction, since it replaces the rollers with
    30 a conductive pulley of the cable and has as its main characteristic that the cable always leaves on the same line. This system however twists the cable considerably, making its use not recommended for cables containing fiber optic sections, as it would damage them considerably.
    35 On the other hand, the systems described above need to be activated by a type of image2 left along the axis of the reel.
    image3
    US 3122341 refers to a stowage system that does not need drive and also does not twist the cable. It is the cable tension itself that
    5 displaces the docking pulley in its axial movement. On the contrary, this system, having an adjustable pulley cause, as a result of that orientation at the exit of the cable, a misalignment at the entrance of the reel, which causes friction of the cable with itself, since it is the previous loop that positions by the friction the cable entry.
    10 The systems described, although they have valid solutions in the field of cable stowage, do not end up solving the problem of friction in the stacking. This aspect is critical when extending the cable life, especially if we talk about umbilical cables for L.A.R.S.
    fifteen Description of the invention
    The present invention aims at a machine for cable stowage, which allows carrying out the stowage operation, without friction or friction.
    20 twists of the cable, which will prolong the life of the cable and eliminate the risk of breakage of optical fibers, in case the cable is the carrier of the same.
    The machine of the invention is of the type initially indicated and comprises a docking carriage that is movable, on a set of guides and by means of a drive mechanism 25, in a direction parallel to the axis of the reel. This carriage is a carrier of two pulleys on which the cable rests during the stowage operation, a first pulley receiving the cable to be wound, which is orientable around a first axis perpendicular to the axis of the reel and rotating on a second axis perpendicular to the first cited shaft, and a second pulley that is located between the first pulley and the
    30 reel and is rotatable on a third axis parallel to the axis of the reel.
    The carriage is mounted on guides parallel to the axis of the reel, preferably on two guides, and is related to the drive mechanism mentioned above.
    35 The guides may consist of bars parallel to the axis of the reel, on which the carriage is mounted through carriage bushes of said carriage and movable on the guides.

    image5
    5 On the other hand, the driving mechanism of the stevedoring car may consist of a spindle that is parallel to the guides of said carriage, this spindle being mounted on a non-rotating nut that is integral with the carriage. Turning the spindle in one direction or another achieves the linear displacement of the nut on the spindle, which drags the carriage over the guides, also in one direction or another.
    10 The first pulley is mounted, through the second axis of rotation, on a support that, in turn, is mounted on the car through the first axis of rotation, perpendicular to the axis of the reel and on which said support is orientable in one way or another.
    15 The second pulley is mounted on the stowage car through the third axis of rotation, which is parallel to the axis of the reel.
    According to a preferred embodiment, the first and second pulley are arranged so that their throats are aligned on one side in a direction perpendicular to the axis of the reel, thus facilitating the passage and conduction of the cable on the two pulleys.
    Preferably, the first axis of rotation, on which the first pulley is orientable, is aligned with the direction of exit of the cable of the first pulley towards the spool. This first axis can be defined by two aligned bearings, through one
    25 of which can pass the cable at its exit from the first pulley to the reel. Brief description of the drawings
    In the accompanying drawings an exemplary embodiment is shown, not limiting, which includes the constitution and characteristics of the invention, being: Figure 1 a perspective view of a docking machine constituted according to the invention. -Figure 2 an upper floor of the same stevedoring machine. 35 - Figure 3 a vertical section of the stevedoring machine, taken along the line III-III of Figure 2.
    image6 Detailed description of one embodiment
    The machine shown in the drawings comprises a reel (1), on which a cable (2) will be wound, and a docking car (3) that is movable in a direction parallel to the axis of the reel (1), as will be explained later , and is a carrier of means for guiding the cable (2) towards the reel (1).
    The guided means mentioned are composed of two free-spin pulleys, a first pulley (4) that is mounted on the steverod (3) through an intermediate support (6) that is orientable around a first axis of rotation ( 7) perpendicular to the axis of the reel (1). In the support (6) the pulley (4) is rotatable about a second axis (8) perpendicular to the first axis (7).
    On the other hand, the second pulley (5) is mounted directly on the stowage car (3) through a third axis of rotation (9) parallel to the axis of the reel (1).
    As can be best seen in Figure 3, the first axis of rotation (7) may be materialized by two bearings or bearings (10-11) aligned perpendicular to the axis of the reel (1). On the other hand, the first and second pulley (4-5) are arranged with their throats in alignment in the direction perpendicular to the axis of the reel (1), coinciding with the first axis (7), passing the cable (2) through the bearing or bearing (11).
    The dock carriage (3) is mounted on guides that can be materialized in bars (12 and 13) parallel to the axis of the reel (1), and in bushings (14 and 15) mounted on the bars (12 and 13), with the power sliding along them, and in solidarity with the car (3). The bushing (15) can fully embrace the bar (13), while the bushing (14) can hug the bar (12) in an amplitude of 180 °, thus facilitating the lifting and dismounting of the stevedore carriage (3).
    The pulleys (4 and 5) can be made of nylon cast iron, with a diameter that will depend on the minimum radius of curvature of the cable (2).
    The machine of the invention incorporates a drive mechanism of the stevedoring carriage (3), which may be constituted by a spindle (16), parallel to the bars (14 and 15), on which a nut (17) is mounted. swivel, carriage carriage (3). Turning in one direction or another the spindle (16) achieves the linear displacement of the
    nut (17) that drags the carriage (3), movable on the bars (14 and 15) in one or image7
    image8
    spindle (16), since in other directions the stevedoring carriage (3) has freedom of tilt around the bar (13), of circular section. The objective is to prevent the spindle (16) from absorbing bending forces and that its threading can be damaged, all this
    5 thanks to the removable support defined by the bushing (14) that rests on the bar (12) in an amplitude of 180º.
    With the constitution described, both the exit of the cable (2) to the first pulley (4) and to the reel (1), from the docking car (3), will be orientable exactly to the point where we want the cable to reach. A common problem in the adjustable pulley systems 10 is that the pulley, when oriented towards a point at the exit, does not deliver on the stretch and on the corresponding layer at the entrance, since the "natural" input and output of the pulley is Tangent to it. For each point of the cable at the exit there is its corresponding to the input (following the “natural” tangent path without friction). If we aim the pulley towards a point at the exit and we want
    15 change the point at the entrance, friction will occur, since naturally the cable will tend to get that position by friction of the cable.
    The solution involves aligning the axis (7) of orientation of the first pulley (4) with the direction of exit of the cable (2) towards the spool (1) in the first layer. In this way even though the first pulley (4) rotates and aligns with the pulley (5), the cable 20 will enter the reel in the same position as long as we do not complete the first layer. If we continue to stow cable and climb the layer, this option will no longer be valid (it would only be when the pulley was with 0º of misalignment at the exit of the center of the reel) since when reaching the end of the reel (coinciding with the maximum angle misalignment at the exit) the “natural” cable entry to the reel would go out of
    stowage area, causing friction between the cable and the wing of the reel. To solve this problem, the second non-adjustable pulley (5) is introduced, which will absorb the misalignment and deliver the cable perpendicularly to the reel in any position.
