Definitions
- the present invention relates to a reel for winding and unwinding a link in particular for energy transmission and / or data transmission, such as a cable, a pipe, an optical fiber or the like, as well as a method. manufacturing such a coil.
- coils intended for winding and unwinding a link for example a link of the type allowing the transmission of energy and / or data transmission.
- such a coil comprises:
- the structure of the coil is stiffened by ferrules, namely:
- each ferrule is attached to at least one arm of a respective cheek at a second distance from the mandrel, greater than the first distance.
- the coil comprises a bearing surface adapted to receive the turns of the link, the inner turn being in contact with said bearing surface.
- Said bearing surface may in particular form part of the mandrel or of the inner shell.
- the flange that is to say the distance between the two cheeks, is defined according to the width of the link to be wound on the spool. To allow correct winding / unwinding of the link, especially in the case of a single-turn coil, the flange is adjusted so that the distances between the cheeks are adapted to the link wound at the proximal and distal ends of the arms.
- a current trend is to reduce the width and / or thickness of the links, which allows, for the same coil diameter, to wind a greater length of link and a greater number of turns on the bearing surface.
- a reduction in the dimensions of the link involves reducing the air gap.
- One element limiting the reduction of the flange is the thickness of the mandrel, that is, its dimension parallel to the axis of rotation of the coil.
- a reduction in the thickness of the mandrel leads to a reduction in the rigidity of the coil, which results in an increase in the amplitude of displacement of the distal ends of the arms relative to the mandrel, in particular under the effect of a axial stress, whether static or dynamic such as wind.
- a significant thickness of the mandrel makes its manufacture expensive. Indeed, for a thickness typically greater than 25 mm, the sheet metal cutting processes by laser are not suitable and must be replaced by processes having technical limitations and / or more expensive, such as flame cutting or drilling by. a drill press.
- An object of the invention is to design a coil having improved rigidity and reduced mass while being manufactured at lower cost.
- the invention provides a reel for winding and unwinding a link, comprising:
- a mandrel extending around an axis of rotation of the reel, - a plurality of pairs of lateral arms extending on either side of the mandrel, together playing the role of cheeks defining between them a winding volume of the link, said coil being characterized in that it comprises a closed flange fixed to each of the arms constituting one of said cheeks, said flange having a thickness of between 10 and 40 mm.
- the flange has a continuous shape closing on itself. Considered in section in a plane orthogonal to the axis of rotation of the coil, around which it extends, the flange is therefore delimited by a closed internal contour and a closed external contour, the distance between the two contours being defined as the width of the flange.
- the flange may have an annular shape, that is to say with concentric circular inner and outer contours, but it is not limited to this particular shape of the contours. More generally, the inner and outer contours of the flange can include curved portions and / or rectilinear portions.
- said flange has a thickness suitable for being cut by a laser, for example between 10 and 25 mm.
- the flange has a thickness identical to that of the mandrel.
- the mandrel has a thickness of between 20 and 40 mm.
- the outer shape of the mandrel coincides with the inner shape of the flange.
- the flange may have a width of between 30 and 100 mm.
- the flange is fixed to each arm constituting one of the cheeks by threaded rods or screws, each threaded rod or screw passing through an oblong hole in the flange and an oblong hole in the respective arm, said oblong holes being oriented in substantially orthogonal directions.
- Another object of the invention relates to a method of manufacturing a coil as described above.
- Said method comprises the following steps:
- step (a) comprises cutting the mandrel and the flange from a single sheet metal, the flange extending around the mandrel.
- the cutting in step (a) is performed by a laser.
- Figure 1 is a perspective view of a known coil
- Figure 2 is a front view of the coil of Figure 1;
- Figure 3 is a sectional view of the coil of Figure 1;
- Figure 4 is a perspective view of a spool according to one embodiment of the invention.
- Figure 5 is a sectional view of the coil of Figure 4.
- Figure 6 is a detail view of the coil of Figure 4.
- Figure 7A illustrates the displacements (in mm) of the arms for a coil of known type with a mandrel thickness of 20 mm, calculated by a digital simulation
- FIG. 7B illustrates the displacements (in mm) of the arms for a reel according to the invention, the thickness of the mandrel of which is 20 mm, calculated by a digital simulation.
- the coil comprises a mandrel 10 extending around an X axis of rotation of the coil.
- the mandrel 10 has a cylindrical shape of revolution, the axis of which coincides with the axis X.
- the external shape of the mandrel may consist of a plurality of facets, s' each extending in a plane parallel to the X axis; preferably, the different facets are all located at an equal distance from the X axis.
- the mandrel 10 has two opposite faces orthogonal to the X axis.
- the mandrel is typically cut from a metal sheet.
- the thickness of the mandrel is typically between 20 and 40 mm.
- the coil further comprises two cheeks which extend on either side of the mandrel.
- the cheeks define between them a winding volume of the link, adapted to laterally contain the turns of said link.
- the flange is defined according to the width of the link to be wound on the spool. More precisely, in the case of a single-turn coil, the flange is slightly greater than the width of the link to take into account the dimensional tolerances linked to the manufacture of the link; in the case of a multi-turn coil, intended to receive several adjacent turns, the flange is slightly greater than the sum of the widths of the adjacent links.
- the cheeks guide the winding and unwinding of the tie.
- Each cheek is formed by a set of side arms 20a or 20b which extend radially from the mandrel.
- the proximal part of each arm is rigidly secured to a respective face of the mandrel, for example by means of threaded rods.
- the arms forming one of the cheeks can be attached directly to one face of the mandrel, while the arms of the other cheek can be fixed at a determined distance from the opposite face of the mandrel to achieve the desired flange. This distance can in particular be adjusted by means of a device for adjusting the flange as described in document WO 2014/167105.
- Each cheek is planar, that is, the faces of the arms opposite the mandrel are coplanar, and extend in a plane orthogonal to the X axis of rotation of the mandrel.
- the arms are for example formed by bending a metal sheet or can be made from metal profiles.
- the link may have a round section (in which case the width and thickness of the link are equal to its diameter), which is particularly the case for multi-turn coils, which are substantially rectangular (in which case the width of the link is the dimension which extends along the X axis and the thickness is the dimension perpendicular to the width), or any other section depending on the intended application.
- the structure of the coil is stiffened by ferrules, namely:
- each ferrule is attached to an arm of a respective cheek at a second distance from the mandrel, greater than the first distance.
- the outer ferrules can be attached to the distal end of the arms.
- Each ferrule may consist of a single piece or of a plurality of portions each extending in an angular sector around the X axis.
- each ferrule can include a removable portion, as described in document WO 2015/071341.
- the coil comprises a bearing surface adapted to receive the turns of the link, the inner turn being in contact with said bearing surface.
- the bearing surface generally has a cylindrical or spiral shape.
- the bearing surface can in particular form part of the mandrel (this is then the cylindrical surface of the mandrel or a surface added, rigidly secured to the mandrel) or to the inner ferrule (each ferrule portion then having a surface in the form of a cylinder or spiral portion, the assembly of the various portions forming a continuous cylindrical or spiral surface, which is the bearing surface).
- a closed flange 40 is also fixed to the arms 20a.
- the flange can, for example, be formed by cutting a metal sheet. The flange is thus flat.
- the flange preferably has a constant thickness.
- the flange typically has a thickness between 10 and 40 mm, preferably between 10 and 25 mm.
- the flange is cut from the same sheet as the mandrel. All that is needed is a cut (for example laser) according to the outer shape of the mandrel - which also coincides with the inner shape of the flange, and a cut according to the outer shape of the flange, to form both the mandrel and the flange and this without loss of material except for any offcuts corresponding to the sheet located outside the flange.
- a cut for example laser
- the mandrel and the flange can be formed from a sheet of stainless steel.
- the mandrel and the flange can be formed from a sheet of steel and then receive a protective treatment, for example by galvanizing or painting.
- the flange is provided with orifices 400 for the passage of threaded rods or screws 41 necessary for fixing the flange to the arms.
- each arm is provided, at the location provided for the flange, with an orifice 200 for the passage of said threaded rods or screws.
- the orifices 200 and 400 are oblong. Even more preferably, as illustrated in FIG. 6, each oblong orifice 200 is oriented substantially perpendicular to the corresponding oblong orifice 400, which makes it possible to absorb dimensional dispersions in two directions.
- the oblong holes 200 extend at a tangent to a mid-circle of the flange, and the oblong holes 400 extend lengthwise of the arms 20a.
- the width of the flange is chosen large enough to allow the passage of the threaded rods and to present adequate mechanical strength. Typically, the width of the flange is between 30 and 100 mm for an outside diameter of 1000 to 3000 mm. The width of the flange is preferably constant.
- Such a flange by connecting the arms of the same cheek to each other, has a function of absorbing the forces exerted on the arms, which has the effect of increasing the rigidity of the coil and also of increasing its stability during its lifting from the horizontal position (which is typically the position in which the spool is assembled) to the vertical position (which is the usual use position of the spool).
- the bridle thus acts as a reinforcement.
- the presence of the flange makes it possible to reduce the thickness of the mandrel without penalizing the rigidity of the coil, which provides a significant saving in weight and cost of the coil.
- This stiffening can be obtained with sheets of relatively thin thickness, especially less than 25 mm, it allows the use of laser cutting processes.
- the coil being simulated has a 20mm thick mandrel. Compared to a known reel whose mandrel has a thickness of 40 mm, this reel has a reduced mass, a lower cost, and makes it possible to wind a cable of small width, that is to say of the order of 20 mm.
- the simulations aim to check the behavior of the coil in response to a wind force.
- the wind force Fv exerted by the wind on the mandrel is defined by the formula:
- C x is the drag coefficient of the coil; C x is equal to 1, 2, i.e. the drag coefficient of a disc,
- V is the wind speed (in m / s); in the simulation, a maximum speed of 70 m / s is tolerated,
- S is the area of the link wound on the spool:
- This spool includes a 20mm thick mandrel.
- the flange and the mandrel are cut from the same sheet of 2 mx 2 m.
- the mandrel has a circular shape and the flange has an annular shape, the inner shape of which coincides with the shape of the mandrel.
- the outer diameter of the mandrel is 1850mm, corresponding to the inner diameter of the flange, and the outer diameter of the flange is 1975mm.
- the maximum displacement at the distal end of the arms under a wind of 70 m / s is 27 mm (see figure 7B), that is to say reduced by a factor of 18 by compared to the coil without the flange.
