Definitions
- the subject of the invention is a carousel winder for the winding of a product in band on one or the other at least two winding mandrels.
- Tape production facilities metallic generally include several sections having different functions, such as hot rolling, pickling, cold rolling, and finishing.
- a winder comprising a mandrel consisting of a shaft rotated around its axis and to which can be fixed, in a removable manner, the end of the strip.
- the mandrel extends overhang from a frame carrying the drive means in rotation of the mandrel and is provided with a system allowing shrink it to allow removal of the spool.
- the strip is kept under tension to tighten the turns.
- the coil When the coil reaches the desired diameter, corresponding to a certain strip length, it is removed from the mandrel.
- the first mandrel is then released and can return, by rotation of the chassis, in the first position of start-up.
- the second mandrel, on which have the first turns is placed in the full winding position.
- the winder could include three mandrels placed successively, by rotation of the chassis, in a first start position, a second full winding position and a third position of unloading.
- each mandrel expands, normally, cantilevered, from the rotating chassis so as to allow the withdrawal of the wound coil by axial sliding towards the side opposite to the chassis.
- the coil being very heavy, it is preferable, during winding that the opposite end of the mandrel to the chassis rests on a removable counter bearing, for example US-A-2707596.
- the counter bearing is simply placed on an erasable support forming a chair resting on the ground or on part of the frame fixed.
- the support chair At the end of the winding, the support chair is away from the mandrel to allow removal of the spool.
- the object of the invention is to remedy these disadvantages thanks to a new provision allowing support the mandrel in all positions and even during the rotation of the rotating frame.
- a paper roll winding device comprising several winding rods mounted on a support star which can rotate in stages so as to pass each rod in multiple positions, respectively threading a support sleeve, gluing, fixing the end of a strip, winding and roller discharge.
- the free end of each rod can be supported by a articulated arm mounted on a second star support and of which the opening is controlled by an indexing system to allow the evacuation of the coil and the threading of the muff.
- Such a device intended for manufacturing in series of toilet paper rolls, wouldn't usable for reel reel of a strip metal which must be maintained, during all the winding, under a traction which can exceed a tonne.
- the invention does, however, resolve this problem and therefore relates, in general, to a winding installation in reels of a strip metallic, comprising a rotating chassis mounted rotatably around a central axis on a fixed frame, two mandrels expandable mounted on the rotating frame and on the other of the central axis, each around an axis eccentric parallel to the central axis and each extending in overhang on the same side of the rotating chassis, from a first end of installation on the chassis to a second opposite end, means for selective control of the rotation of each mandrel around its axis for winding the metal strip and means for controlling the rotation of the chassis rotating around its central axis, for the establishment selective of a first mandrel in a first position for fixing the end of a strip metallic and winding start with setting belt tension, then the passage of said first mandrel from the first position to a second position diametrically opposite, spool discharge wound, with simultaneous return of the second unloaded mandrel from said unloading position to the
- the installation includes a permanent support means for the free end of the mandrel during winding, likely to rotate with the chassis at an angle of 180 ° rotation between the first start position and the second position of complete winding of the reel and unloading by casing the increasing coil weight and tensile force applied by the strip, said permanent support means comprising at least one support rod extending along a direction parallel to the central axis, at least on one length greater than the width of a coil, between a end embedded in the rotating frame and a opposite end, at least one support arm having a first end hinged around an axis on the end opposite the support rod and a second end carrying a removable support member, control means rotation of said at least one support arm around its axis between two positions, respectively, a first engagement position of the removable support member
- the articulation axis of the support arm can be perpendicular to the central axis, the support arm coming then place yourself in a plane substantially parallel to this axis, in the unloading position.
- the axis of articulation can also be parallel to the central axis, the support arm then being offset angularly with respect to the mandrels so that the organ support is far enough away from said mandrels to not not hinder the discharge of a coil completely wound.
- the arm of support is articulated on a single rod forming a tree support centered on the central axis of rotation of the chassis turning.
- the central support shaft can advantageously be mounted rotatable about the axis on said rotating chassis with possibility of angular sliding, the winder comprising means for applying to the shaft of support, of a torque around the central axis adjusted to compensate for the weight of the current reel of winding and the torque resulting from the traction exerted on the tape, so that the resultant of the whole forces applied to the support arm by the mandrel during winding is exercised in a direction passing substantially through the central axis of the rotating chassis.
- the arm of support of the support member comprises two branches articulated respectively on two offset support rods symmetrically on either side of the plane passing through the mandrel axes, at a sufficient distance from it to allow the winding of a coil on each mandrel up to a maximum radius corresponding to the distance between the central axis and the axis of the mandrel.
- each support rod forms a beam extending cantilevered from the rotating frame and having a cross section of inertia sufficient to resist to the forces applied to the mandrel by the strip under traction.
- the removable support member comprises a counter bearing likely to engage, by displacement relative axial, on a pin at the end of the mandrel opposite to the rotating chassis.
- each mandrel is of the type comprising segments which can be moved radially under the action of a control rod sliding axially in a bore of the mandrel shaft.
- the mandrel support pin is advantageously provided at the end of the control rod and can engage removably, by axial displacement of said rod, in a housing corresponding to the arm of support after the installation of the latter in the axis of the mandrel.
- the removable support member consists of at least two jaws each placed at the end of a mounted arm pivoting on a support rod about an axis parallel to the central axis, between an open position for which the two jaws are far enough apart from the mandrel to allow removal of the coil, and a closed position for which the jaws are tightened on the end of the mandrel in the manner of pliers.
- the two-winder mandrels is equipped with two support members each consisting of a pair of jaws and mounted on two swivel arms each carrying two jaws belonging respectively to each of the two support members so that one or the other of the two mandrels is supported alternately by pivoting the two arms in one direction or in the other, the two jaws of a pair being in closed position on one of the chucks when both the jaws of the other pair are spread apart, in position open on either side of the other mandrel, so that allow unloading of the wound reel.

- Figure 10 and Figure 11 show, in view of face, two other embodiments of the invention.
- Figure 12 shows the operating steps of the embodiment of Figure 11.
- a carousel winder conventionally comprising a revolving frame 1 rotatably mounted around a central axis 10, the chassis consisting, for example, of a drum cylindrical rolling on separated rollers 11 mounted rotary on a foundation block 12 or a fixed frame, each around an axis parallel to the central axis.
- a way rotation control such as a pinion 13 driven in rotating and meshing with a toothed crown not shown, formed on the periphery of the drum 1 allows to rotate it around its axis 10.
- chassis 1 On chassis 1 are mounted two mandrels winding 21, 22 extending in overhang from the chassis 1 and on the same side thereof.
- Each chuck 21, 22 is mounted on a shaft 2a, 2b and can be driven in rotation about an axis 20, 20 'parallel to the axis 10 of the rotating chassis 1 by means, for example, of a motor autonomous 23, 23 'mounted in the chassis 1.
- the motor rotation 23 can be hydraulic or electric.
- Each mandrel is made, in a conventional manner, a tree 2 associated, as shown in FIG. 9, with a set of adjacent segments 26 mounted sliding radially on the shaft 2 and actuated by a rod 25 passing through an axial bore of the shaft 2 and carrying a rack which controls the expansion of the mandrel by segment spacing for hooking and winding of the band and then tightening the segments for allow the coil to be removed at the end of the winding.
- the rotating chassis allows place each of the two mandrels successively in a first winding start position A then in a second position B for complete winding and extraction of the coil.
- the two positions A and B are diametrically opposite, so that one of the mandrels 21 either in the start position A when the other mandrel 22 is in position B for extracting the coil.
- the shaft 2 of each mandrel is embedded in chassis 1 at its end turned towards it and thus extends cantilevered supporting the weight of the reel 3.
- the end 24 of the shaft 2 of the mandrel opposite the chassis 1 can, depending on the invention, to be removably supported on the solid mass of foundation 12 or on a fixed frame, via a rotary support member 4.
- the support member 4 comprises a counter bearing 40 mounted at the end of a support arm 41 which, at its other end, is mounted on the end of a central shaft 5 centered on the central axis 10 and of which the opposite end 51 is embedded in the chassis turning 1.
- the support arm 41 is articulated on the free end 52 of the central shaft 5 around an axis 42 perpendicular to the central axis 10 so as to allow 180 ° rotation of the support arm 41 with the counter bearing 4a
- the latter is, on the other hand, arranged so that its two lateral faces 43, 43 ′ can engage so removable on a pin at the end 24 of the shaft 2 of the mandrel.
- the rotation of the arm 41 can be controlled by any means, easy to design and supported by the central shaft 5, for example, an actuated rack 53 by a jack 54 and meshing on a pinion centered on the axis 42 and integral in rotation with the arm 41.
- the counter-bearing 40 can be equipped, on its two lateral faces 43, 43 ', of two contiguous bearings committing, in one way or the other, to one or the other of the journals with a clearance allowing the arm rotation 41.
- This operation can be carried out during the time necessary for the engagement of the head 31 of the band of the new coil on the mandrel 21.
- the mandrel 21 is supported, at its end 24 ', by the support member 4.
- the tensile force applied to the strip for allow the winding thereof does not result in bending of the mandrel 21 which is held at its two ends respectively by the rotating frame 1 and by the member support 4 and the corresponding reaction is transmitted to foundation mass by the arm 41, the central shaft 5 and the chassis 1.
- the central shaft 5 which is embedded, by its end 51, on chassis 1 may have rigidity necessary to absorb this reaction.
- the opposite end 52 of the central shaft 5 build directly on the foundation, by example by means of a counter bearing 55 which can engage from removably on the end 52 of the shaft 5, the counter bearing 55 being carried, for this purpose, by a support arm 56, for example as shown in Figure 2.
- the arm 56 carrying the counter bearing 55 and bearing on the foundation block 12 is rotatably mounted around an axis 57 spaced from the central axis 10 and from the axis 20 of the mandrel 21.
- the support arm 41 is mounted pivoting around the axis 42, on the end 52 of the central shaft 5 and the latter can be secured in rotation with the rotating frame 1 so as to rotate with this one when we pass the shaft 21 from the position start A to full winding position B.
- the organ support 4 remains engaged on the journal of the mandrel 21 and therefore allows it to withstand the tractive effort applied by the strip without risk of bending of the mandrel 21, the reaction being taken up by the central shaft 5.
- the tree central 5 is rotatably mounted around axis 10 on the rotating frame 1, so as to allow sliding angular and is associated with a torque motor 61, fixed on a extension 6 of the shaft 5 and making it possible to apply to this one a torque.
- the strip 32 is subjected to tensile stress T whose distance to the axis of rotation 20 gradually increases, as well as the weight P of the coil 30 which is added to the self-weight of the arm 41.
- the torque motor 61 exerts on the central shaft 5, a direction compensation pair reverse, which is permanently adjusted according to the length of wound tape and orientation of the stretched strand 32 so that the reaction applied to the support arm 41 which is the result of the tensile force T applied on the strip and the weight of the reel 30, passes substantially by the central axis 10.
- Figure 5a shows the start position for which the load P applied to the axis of the mandrel is relatively small, for example a ton. Traction applied can be of the order of 2.5 T. The resulting R, directed upwards, is compensated by an opposite force R ' having an R'x component taken up by the support arm and a component R'y taken up by the application of the torque. We sees that, in this position, the support arm OA is subjected to traction and the torque is applied in the direction trigonometric.
- the applied load P can be of the order of 20 T and the traction T of approximately 7 T, the scale of representation of the forces being modified.
- the resultant R is directed downwards and the charge P is mainly taken up by the support arm OA which is compressed.
- the couple is then directed in the direction negative, opposite to the tensile force.
- Figure 5c corresponds to the position of unloading after complete winding.
- the charge P can be 30 T, the pull being 15 T.
- the torque is applied again in the positive direction and compensates essentially the charge P.
- a brake 60 capable of blocking the rotation of the shaft 5.
- the winder can operate, either with application of a modulated compensation torque, i.e. with securing of the central shaft.
- the two mandrels 21, 22 are associated, respectively, with two support members 4a, 4b each mounted at the end of an arm support 41a, 41b articulated on the end of the shaft central 5 around an axis (40a, 40b) perpendicular to the central axis 10.
- the two support arms 41a, 41b can be articulated on a part 44 forming a core which is keyed on the end 52 of the central shaft 5 so as to rotate therewith.
- Each arm 41a, 41b can be associated with a jack rotary hydraulic 45a, 45b which controls the rotation of the arms around its axis.
- the counter bearing 40 placed at the end arm 41a, 41b is arranged so as to be able to engage in one direction on the end 24 of the mandrel, by rotation around its axis.
- the counter-bearing 55 for supporting the central shaft 5 is mounted at the end of a rod 5 'placed in the extension of the shaft 5 so as to allow the rotation of one or the other of the two arms 41a, 41b for the release of the corresponding support member 4a, 4b.
- the counter bearing 55 does not hinder the discharge of the coil and can be mounted on a fixed support resting on the foundation 12.
- Central shaft 5 must have a minimum section ensuring sufficient rigidity to withstand the reaction chucks. As a result, the maximum diameter of the coil that can be wound on each mandrel is limited at the distance between the axis 20 of the mandrel and the periphery of tree 5.
- each support arm 41 carrying a support member 4 consists of two branches 45, 45 ' articulated respectively on the two support rods 7, 7 ' around axes 46, 46 'which are aligned and perpendicular in plane P 'passing through the axes of the two mandrels.

- the winder is equipped with two support members 4a, 4b carried respectively by the ends of two arms 41a, 41b which are pivotally mounted on the end of a central shaft 5, around the axis 10 thereof.
- each arm 41a, 41b can be associated with a toothed sector 61 ′ on which a fixed gear 62 rotated by a non-mechanism shown which can advantageously be mounted in a fixed support member 56 'carrying a centering bearing of the end of the shaft 5 opposite the rotating frame 1, the fixed support member 56 'can be simply fixed on the frame or the foundation 12.
- each organ support 4 can be placed by simple rotation of the support around axis 10, in line with the axis of a mandrel, either in a separated position C 'for which the support arm 41 is, for example, perpendicular to the plane passing through the axes of the mandrels 21, 22.
- the latter advantageously comprises a counter bearing 40 carried by a piece 47 slidingly mounted axially on the end of the support arm 41 which carries a sliding control member 48, for example a cylinder or screw-nut system.
- a winding mandrel usually consists of a set of segments mounted to slide radially on a rotation shaft and whose expansion can be controlled or shrinking it by means of a sliding control rod axially.
- the support member 4 includes a counter bearing 40 which can be mounted on the end 27 of the expansion rod 25 and engages in a corresponding housing 47 'formed at the end of the support arm 41, when sliding axially the control rod 25 to determine the expansion of the mandrel. Conversely, at the end of the winding of a reel, the control rod is moved back to determine the shrinking of the mandrel and, at the same time, the counter bearing 40 is released from the housing 47 ′, which allows the pivoting of the arm 41 in the separated position C '.
- the counter-bearing which constitutes the removable support member may be formed by two half-bearings formed on two movable jaws likely to tighten, like a clamp on the end 24 from the mandrel shaft, or move away from it to allow unloading of the wound reel.
- each of the two arms can advantageously carry two jaws belonging, respectively, to each of the two support members.
- the support member 8 consists of two jaws 8a, 8b each placed at one end of an arm 81a, 81b which carries, at its other end, a jaw 8'a, 8'b of the other support member 8 '.

- each arm 81 is offset laterally with respect to pivot 82 of such so that the planes P1, P2 passing through the central axis 10 and the centers of the jaws 8a, 8'a form an obtuse angle.
- Each of the two arms 81a, 81b, is provided with a sector toothed 61 'on which meshes a pinion 62 actuated by a mechanism mounted on the rotating frame 1 and capable of turn the arm 81 in one direction or the other.
- the two jaws 8a, 8b come to tighten, like a pliers, on the end 24 of the shaft of one of the mandrels 21 while the other two jaws 8'a, 8'b deviate from the other mandrel 22 of sufficient distance to allow removal of the wound coil.
- the arms 81 of support of the jaws remain in a plane perpendicular to the central axis 10.
- the central shaft 5 can therefore either extend in overhang from the rotating chassis 1, either rest on a fixed support by its opposite end to chassis 1.
- the arms 83a, 83b, for supporting the support members 8, 8 ' are articulated, respectively, on pivots 82a, 82b with axes parallel to the central axis 10 and formed on the ends two rods 7a, 7b, each forming a support beam, analogously to the embodiment of FIG. 6.
