Definitions

  • the present invention relates to a machine for winding web-like materials.
  • web-like materials are packaged in the form of reels obtained by winding the web-like materials on suitable rods that act as supports during the winding. When a reel has been completed, its rod is removed for reuse.
  • the web-like materials wound as reels are generally intended to undergo different transformations according to the specific applications and they can be, for example, paper or non-woven fabric.
  • the transformations can include, for example, the unwinding and a new rewinding of the material in order to produce rolls with a diameter smaller than that of the starting reels, intermediate embossing operations between the unwinding and the subsequent rewinding, the transversal cutting of the rolls to obtain products of axial length shorter than that of the starting reel, etc.
  • winders The machines by which the winding is carried out are generally called “winders” and they typically include a structure that allows the web-like material to pass over a winding roller against which the rod on which the reel is formed is pushed.
  • the reel during its formation, is kept in contact with the winding roller due to the thrust exerted through the rod which, in turn, is held by suitable supports allowing it to be translated along the guides formed in the aforementioned structure. Cyclically, when a reel is completed, i.e.
  • the web-like material is interrupted, the completed reel is distanced from the winding roller moving it to an unloading station while it is still on the relative winding rod, and another winding rod is positioned on the winding roller to form a new reel.
  • the winding rods are generally stored in a superstructure of the machine in a position above the winding roller. It is therefore necessary to provide a mechanism for removing the winding rods from the storage point and positioning them in the area of the machine where the reels are formed.
  • US4768730A also discloses a machine for winding web-like materials in the form of reels, comprising a winding roller over which the web-like material intended to be wound passes, wherein the winding roller cooperates with a winding rod on which the web-like material is wound to form a reel, wherein the winding roller is positioned in a corresponding containment structure, wherein the winding roller is oriented transversely to said structure, and wherein the machine is served by a storage in which several winding rods can be stored and a mechanism for removing the rods from said storage.
  • the mechanism for picking up the rods from the storage consists of several distinct groups of arms which exchange with each other the rods taken from the storage in such a way that each arm is intended to perform a specific operation: a first arm picks up the rods and delivers them to a second arm, the second arm receives the rods from the first arm and subsequently delivers them to a third arm which, in turn, moves them parallel to the winding roller to start a winding cycle. Also in this case, the problems relating to the spaces required for the installation and operation of the machine remain unresolved.
  • EP0849202A1 also discloses a machine for winding web-like materials in the form of reels, comprising a winding roller over which the web-like material intended to be wound passes, wherein the winding roller cooperates with a winding rod on which the web-like material is wound to form a reel, wherein the winding roller is positioned in a corresponding containment structure, wherein the winding roller is oriented transversely to said structure, and wherein the machine is served by a storage in which several winding rods can be stored and a mechanism for removing the rods from said storage. Also in this case the picking of the rods from the storage is managed by means of arms which are distinct from those which move the rods around the winding roller.
  • the present invention relates, in particular, to the removal of the winding rods from the respective storage point and to their movement during the winding of the web material and it aims at providing a system for controlling the winding rods that is structurally simple, precise, reliable and more compact than the known pick-up mechanisms.
  • a machine for winding web-like materials which ensures an improved continuity in the growth of the diameter of the reels progressively formed and a remarkable precision in positioning the rods in correspondence with the winding roller without however involving a particular mechanical complexity.
  • a system for picking up and positioning the rods in a machine in accordance with the present invention allows to control the nip pressure at the winder roller/reel interface and offers the possibility of improving the control of the movement of the reels towards the parking point of the finished rolls.
  • a machine (M) in accordance with the present invention comprises a winding roller (1) on which the web-like material intended to be wound is made to pass.
  • the winding roller (1) cooperates with a winding rod (2) on which the web-like material is wound to form a reel (B).
  • the winding roller (1) is positioned in a structure (3) provided with sides (30) on which two corresponding linear guides (31) are formed parallel to each other and oriented according to a predetermined direction (L) which defines a direction of advancement of the winding rod (2) while the respective reel (B) is forming on the same rod.
  • the winding roller (1) is oriented transversely to said sides, so that its rotation axis (1A) is horizontal.
  • the machine is served by a storage in which several winding rods (2) can be stored and by a mechanism for removing the rods (2) from the storage (S).
  • the rods (2) according to a configuration known per se, have ends (20) adapted to be gripped by a gripping device.
  • the rods (2) have a central cylindrical body (21) which is the very winding surface, i.e. the surface on which the web-like material is wound, and two circular ends (20) that define two corresponding rod gripping portions.
  • the rods (2) have annular grooves that define both the rolling surfaces (22) of the rods on the aforementioned guides (31) and further parts (23) graspable by gripping means as further described below.
  • the web-like material is paper produced by a papermaking machine.
  • said storage consists of a superstructure (32) of the machine arranged at a greater height than the winding roller (1) and comprising supports (33) for supporting and rolling the winding rods (2) with an exit side (33E) from which the rods (2) can be taken, as further described below.
  • the mechanism for removing the rods (2) from the storage (S) comprises two arms (45), that is, one arm (45) for each side of the structure (3).
  • Each arm consists of two elements (4, 5) hinged to each other with a hinge axis (A45) parallel to the rotation axis of the winding roller (1).
  • said arms (45) are positioned externally on the sides (30) of the machine.
  • the first element (4) of each arm (45) can rotate around the axis (A45) of the respective hinge connection with the second arm (5) and the second element (5) can rotate around the winding roller axis (1).
  • the first element (4) of each arm (45) can rotate with respect to the second element (5) which, in turn, can rotate around the axis of the winding roller (1).
  • the second element (5) can be connected to the base structure of the machine (M) by means of a hinge connection having the axis coinciding with the axis (1A) of the winding roller (1), as in the example shown in Figs. 2-5 , or it can be constrained to the superstructure (32) of the machine (M) by means of a hinge connection with axis parallel to the axis (1A) of the winding roller (1), as in the example shown in Fig. 6 .
  • the rotation of the first element (4) of each arm around the axis (A45) is controlled by a first electric gear motor (M4) and the rotation of the second element (5) around the axis (1A) of the winding roller (1) is controlled by a second electric gear motor (M5).
  • the gearmotors (M4, M5) are controlled independently, so that the rotation of each element (4, 5) can be controlled independently from the rotation of the other element of the same arm.
  • said elements (4, 5) are formed by metal plates, that is, by bodies with a predominantly longitudinal development in which two dimensions are prevalent with respect to the third, and are hinged to each other in proximity of two respective end portions (40, 50) side by side.
  • the first element (4) of each arm (45) has a gripping device suitable for gripping a corresponding end of a winding rod (2), as further described below.
  • said gripping device is formed by a gripper (42) comprising a jaw (420) hinged on a free end (421) of the first element (4), which acts as a fixed jaw of the gripper.
  • Said free end (421) is concave, with the concavity facing outwards, and the jaw (420) is mobile, being hinged on the free end of the element (4), and has an internal side (422) which also is concave, so that the concavities (421, 422) respectively presented by the fixed jaw and the movable jaw define, in cooperation with each other, a seat suitable for receiving a corresponding end of a winding rod (2).
  • said seat seen laterally, has a substantially circular shape.
  • the movable jaw (420) can be rotated on the end (421) of the first element (4) by means of a linear actuator (43) which is mounted on one side on an appendix (423) of the first element (4) and, on the opposite side, on an appendix (424) of the same movable jaw (420).
  • the appendix (423) is an upper wing of the first element (4).
  • the appendix (424) of the movable jaw (420) can also be an upper appendix of the latter, so that the actuator (43) does not interfere with the gripping of the winding rods (2).
  • the connection between the jaw (420) and the first element (4) of the arm (45) can be made, for example, by means of a hinge (425) with axis transversal to the first element (4) and to the jaw (420).
  • the actuator (43) controls the rotation of the movable jaw (420) around the axis of the hinge (425) as schematically indicated by the double arrow in Fig.1 .
  • the jaw (420) is in the gripping configuration, being rotated towards the fixed jaw formed on the free end of the first element (4).
  • the actuator (43) determines the opening and closing of the seat for gripping one end of a winding rod (2) by rotating the movable jaw (420) to and from the first element (4) around the axis of the hinge (425).
  • the movable jaw (420) is formed by a metal plate placed laterally offset with respect to the end (421) of the first element (4).
  • the device described above is therefore a gripper arranged on the first element (4) of each arm (45) for gripping and respectively releasing the winding rods (2).
  • the movable jaw (420) can be moved by an actuator different from the one described above, such as for example a rotary actuator (not shown in the drawings) applied on the element (4) and acting on the movable jaw (420).
  • Each arm (45) has an external side, turned towards the outside of the machine (M), and an internal side turned towards the machine (M).
  • the first gearmotor (M4) is applied on the external side of the first element (4), at the point of connection with the second element (5).
  • the stator of the gearmotor (M4) is on the element (4), while the rotor is connected to the element (5). It is understood, however, that the stator of the gearmotor (M4) can be on the element (5) and in this case the rotor will be connected to the element (4).
  • the second gearmotor (M5) is applied on the external side of the second element (5), at the point of connection of the latter to the respective side (30) of the machine (M). In the example of Figs.
  • the stator of the gearmotor (M5) is on the element (5), while the rotor is connected to the connection point of the element (5) with the respective side (30) of the machine (M).
  • the stator of the gearmotor (M5) can be on said connection point and in this case the rotor will be connected to the element (5).
  • Figs. 2-5 illustrate a possible cycle of engagement, movement and release of a winding rod (2A) by means of two arms (45) made as described above.
  • the rod picked up and moved by the arms (45) is indicated with the reference “2A" to distinguish it from the rods that remain on the superstructure (32).
  • Fig.2 In Fig.2 is shown a reel (B) being completed, still close to the winding roller (1). In the same Fig.2 are shown the arms (45) in the position of picking up a rod (2A) from the exit side (33E) of the superstructure (32), with the grippers (42) of the ends (20) of the same rod (2A).
  • the arms (45) are positioning the rod (2A), previously taken from the superstructure (32), on the winding roller (1).
  • the first element (4) of each arm (45) rotates around the axis (A45), while the second element (5) rotates around the axis (1A).
  • the combined rotation of the elements (4, 5) of the arms (45) determines the positioning of the rod (2A) against the winding roller (1) on the upper side of the latter.
  • another rod (2) has taken the place of the one previously taken by the arms (45).
  • Fig.4A is shown the rod (2) placed by the arms (45) in front of the winding roller (1) and the material that forms the new reel (NB) has been wound on it.
  • the completed reel (B) has been moved away.
  • the combined rotation of the elements (4, 5) around the axes (45) and (1A) determines the movement of the rod (2A).
  • the longitudinal axis (X) of the rod (2A) moves along a trajectory which is first parallel to the external surface of the winding roller (1) and then follows the direction of the guides (31), as schematically illustrated in Fig.4B .
  • the rod (2A) rotates around its axis, winding the web-like material on it, material which is fed along a predetermined feeding direction upstream of the winding roller (1) in ways known per se.
  • Fig. 5 shows a further configuration of the arms (45), upon reaching the predetermined diameter of the reel (NB) with the material (W).
  • the arms (45) support the ends (20A) of the rod (2A) on the guides (31) of the machine (M) as the diameter of the reel being formed (NB) increases.
  • annular grooves (22) facilitate the rolling of the rods (2), and therefore of the reels (NB), on the guides (31) of the machine.
  • the grippers (42) mounted on the arms (45) do not block the ends (20) of the rods (2) so as not to prevent the rolling of the same on the guides (31).
  • the grippers (42) define a removable constraint which allows the arms (45) to move the rods (2) from the superstructure (32) to the position of contact with the winding roller (1) and along the guides (31), without however preventing the rods (2) from rotating around their longitudinal axes.
  • the grippers (42) Upon reaching a predetermined final diameter of the new reel (NB), the grippers (42) release the respective ends (20A) of the rod (2A) and the arms (45) can be returned to the position of picking up another rod from the superstructure (32) to start a new cycle.
  • the completed reel is then removed from the machine (M) in ways known per se.
  • the second element (5) of each arm (45) is hinged on the superstructure (32). Everything previously said in relation to the structure and operation of the arms (45) and, more generally, of the machine (M) remains valid. Also in this case, the movements of the rods (2) along the path between the aforementioned storage and the winding station where the winding roller (1) acts is determined by the combination of the rotary movements of the first and second elements (4, 5) of each arm (45).
  • the machine (M) is provided with a carriage (6) mounted on the external side of each of its sides (30) and movable parallel to the same sides of the machine bidirectionally to and from the winding roller (1) by means of a corresponding drive unit (not visible in the drawings).
  • a gripper (60) controlled by a corresponding actuator (61) also mounted on the carriage (6).
  • This device is known per se (in technical jargon it is commonly called “secondary arm”) and, therefore, it is not described in greater detail.
  • a possible way of using the carriages (6) in the context of the present invention is the following.
  • the arms (45) can anticipate the picking up of the rods (2) with respect to reaching the final diameter of the reel to be formed.
  • the arms (45) have already picked up a rod and have positioned it in contact with the winding roller (1) while the reel is almost completed and is engaged by the carriages (6) which can also carry out a "pusher" function by accompanying the completed reel to a predetermined parking point downstream.
  • length of the arms (45) means the sum of the lengths of the elements (4) and (5).
  • the arms (45) can also be used to adjust the pressure of the nip at the winder roller / reel interface.
  • This pressure which in general is within the minimum and maximum values set according to the nature or structure of the web (W) and the winding speed imposed by the winding roller (1), can be regulated through the reciprocal rotation of the elements (4, 5) of each arm (45) which causes a greater or lesser thrust of the rod (2A) against the winding roller (1).
  • a torque load cell (C4) in the hinge for attachment of the first element (4) to the second element (5) and a torque load cell (C5) in the attachment hinge of the second element (5) to the machine structure (M) can also be provided.
  • the load cells (C4, C5) of each arm can be connected to a programmable unit (UE) which controls the gearmotors (M4, M5) of the arms (45) according to a program residing in one of its memory sections.
  • the diagram in Fig. 10 illustrates a possible configuration of the connections between the load cells (C4, C5) with the control unit (UE) to which position sensors (P4, P5) are also connected, suitable for detecting the angular position of the elements (4, 5).
  • the unit (UE) can be programmed not only to carry out the movements of the arms (45) as described above but also to adjust the nip pressure according to the readings of the load cells (C4, C5). It goes without saying that the movements of the arms (45), i.e. the movements of the elements (4) and (5) of the arms (45), are synchronized with each other, so that on the two sides of the machine (M) the movements of the arms are coordinated.
  • the removal of the rods (2) from the storage of the same is performed by two arms (45) which, in addition to the removal of the rods (2), also perform the movement of the same rods along a predefined path which includes their positioning against the unwinding roller (1).
  • the arms (45) also control the translation of the rods (2) along the guides (31) as the diameter of the reels being formed increases, until reaching a predetermined diameter.
  • the two arms (45) are each formed of two elements (4, 5) hinged to each other so that the aforementioned path is formed by a combination of rotary movements around two axes parallel to each other.
  • One of these axes can coincide with the rotation axis (1A) of the winding roller (1).
  • both said axes can be distinguished from the rotation axis (1A) of the winding roller (1), as shown by way of example with reference to Fig. 6 .
  • the two elements (4, 5) are each operated by a corresponding actuator (M4, M5) so that the rotation of each of them can be controlled independently.
  • a rotary actuator (7) can be mounted on the external side of the first element (4) of each arm (45), such as for example an electric motor, which can be used to control the rotation of the rods (20) around the respective longitudinal axes with predetermined angular speed.
  • the actuator (7) is supported by a bracket (70) cantilevered on the external side of the first element (4) of the arm (45) and has an output shaft, oriented parallel to the axis (A45) of the hinge connecting the first and second elements of the arm itself, and facing the gripper (42).
  • a friction disk (71) is applied to said shaft.
  • the actuator (7) is positioned on the bracket (70) so that the friction disc (71) can come into contact with the outer face of the end (20A) of any rod engaged by the respective gripper (42).
  • the rotation of the discs (71) in contact with the external faces of the two ends (20) of a rod (2) determines the rotation of the latter around its longitudinal axis with angular speed imposed by the actuator (7).
  • the actuator is mounted on a carriage (72) to allow it to be moved on the bracket (70), to and from the end of the arm (45) on which the gripper (42) is mounted.
  • said movement of the actuator (7) on the bracket (70) is indicated by the arrow "FA". Movement (FA) is controlled by a corresponding motor not visible in the drawings.
  • the actuator (7) is moved towards the end of the rod engaged by the gripper (42) when it is desired to drag the rod into rotation due to the contact between the end of the latter and the friction disc (71). Conversely, the opposite movement of the actuator (7) determines the disengagement of the rod from the friction disc (71).
  • This mechanism can be useful when the rotation of the rod (2) during the formation of a reel must not be ensured exclusively by the pressure against the winding roller (1).
  • Fig. 12 illustrates by way of example the use of the arms (45) provided with the actuator (7) on the machine (M) in the configuration of Fig. 8 .
  • a machine for winding web-like materials in the form of reels in accordance with the present invention comprises a winding roller (1) on which the web-like material intended to be wound passes, wherein the winding roller (1) cooperates with a winding rod (2) on which the web-like material winds up to form a reel (B), wherein the winding roller (1) is positioned in a structure (3) provided with sides (30) on which two corresponding linear guides (31) are formed parallel to each other and oriented according to a predetermined direction (L) which defines a direction of advancement of the winding rod (2) while the respective reel (B) is formed on the rod itself, wherein the winding roller (1) is oriented transversely to said sides, and wherein the machine (M) is served by a storage (32) in which several winding rods (2) can be stored and by a mechanism per picking up the rods (2) from the storage (32), said mechanism for picking up the rods being constituted by a pair of arms (45) each of which is arranged on a corresponding side of
  • each arm (45) is each moved by a respective actuator (M4, M5).
  • said elements (4, 5) of each arm (45) consist of metal plates with a predominantly longitudinal development.
  • each arm (45) is hinged on the machine (M) with a hinge axis coinciding with the axis (1A) of the winding roller (1).
  • each arm (45) is hinged on said superstructure with a hinge axis parallel to the axis (1A) of the winding roller (1).
