Definitions

  • the present invention refers to a method and apparatus for winding continuous web material.
  • Winders are known in the art which comprise a motor-driven winding cylinder having hinged thereon a support so-called “primary arm” which bears a winding rod brought in contact with the cylinder.
  • the rod moves to a further support, so-called “carriage” or “secondary arm", on which a reel of web material is completed by winding, and which is intended for storage or subsequent work operations.
  • the reel is kept pressed in contact with the cylinder and, depending on the value of contact pressure, there is determined the "squeezing", that is, the density and, thus the softness and quality of the reel in the course of formation.
  • the known winders further comprise kinematic chains for driving the primary arm and the secondary arm, which consist in general of a structure formed by pneumatic and hydraulic components connected to rigid bars or rods.
  • a first drawback is given by the fact that, as the above said kinematic chains are made up not only of rigid elements but also of components that do not exhibit by themselves a rigid behaviour, the kinematic chain presents uncontrolled clearances and displacements of various entity. These clearances generate difficulties in the determination of the position of the winding rod and of the consequent pressure of contact thereof with the cylinder.
  • This first drawback is particularly significant when using winders for generating reels of tissue paper, inasmuch as the pressure of contact to be maintained between the reel in the course of formation and the winding cylinder has to follow, as much as possible, a predetermined pattern throughout the winding operation in order to achieve an appropriate softness.
  • a second drawback is given by the fact that the known winders are not capable of revealing possible winding faults which are likey to cause a reel's quality degree less than desired.
  • the object of the present invention is therefore to overcome the said drawbacks with a method and apparatus for winding continuous web material which allow controlling the winding's basic parameters.
  • this object is obtained with a method and apparatus for winding continuous web material, comprising active means for controlling the motion of the rod-holder support.
  • a winder 1 for reeling continuous web material from a feeding unit comprises a winding cylinder 13 having a motor-driven axis "X" fixed to the bedplate 27 which makes up the surface onto which the incoming web material slides.
  • the winder 1 further comprises supports 23, 3 for a first 31 and second 2 winding rods bringing a reel 30 in the course of formation into contact with the cylinder 13, and controlled actuator means 6, 20 for the adjustment on command of the distance of supports 3, 23 from the cylinder 13 during the winding of the reel 30.
  • the winder 1 comprises also at least one sensor 17 for detecting a contact pressure "P", preferably a load cell located between the reel 30 and the cylinder 13, and a processing unit connected to the actuator means 6, 20 and to the sensor 17 to control the movement thereof in response to the value of pressure "P" detected by the same sensor 17 during the winding stage of reel 30.
  • a contact pressure "P" preferably a load cell located between the reel 30 and the cylinder 13
  • a processing unit connected to the actuator means 6, 20 and to the sensor 17 to control the movement thereof in response to the value of pressure "P" detected by the same sensor 17 during the winding stage of reel 30.
  • the actuator means 6, 20 are respectively made up of electro-mechanical jacks driven by brushless motors 4 via chains, belts or screws, driven by brushless motors 18.
  • the supports 3, 23 consist respectively of a primary arm 3 hinged to the axis "X" of cylinder 13 and connected to an oscillating arm 11 carrying the second winding rod 2, and of winding carriage 23 sliding relative to the cylinder 13 along straight guides 32 and carrying the first winding rod 31. It is understood that in place of the carriage 23 it is possible to provide a "secondary arm" of a type known in the art and, therefore, not to be described herein in greater detail.
  • the primary arm 3 and the oscillating arm 11 are connected to each other by an electro-mechanical jack 6 engaged to an equalizer 26 and a hinge "c".
  • the oscillating arm 11 comprises also a locking clamp 12 operable by a cylinder-piston means 28 fixed to the same arm 11 to retain the second winding rod 2.
  • the primary arm 3 is moved by an electro-mechanical jack 8 driven by one or more brushless motors 10 connected to at least one reducer 9.
  • the sensor 17 which detects the pressure "P" may be in the form either of a toroidal load cell, disposed on the axis "X" of the winding cylinder 13, or of a plate-like load cell disposed on the bedplate 27 or simply on the supports 3, 23.
  • the supports 3 also comprise a protective elastic element 7, preferably disposed between one end of the equalizer 26 and an abutment 25 formed directly on a predetermined region of the primary arm 3.
  • the elastic element 7 is an air spring, the use of this type of eleastic element allowing the user to exactly establish the rigidity thereof by increasing or reducing the internal pressure of the same spring 7.
  • the winding carriage 23 further exhibits driving means consisting of a drive chain 20 and a plurality of sprockets 29 - preferably connected to a brushless motor 18 and its relevant reducer 19 - to move the carriage 23 from the position of reel 30 formation by winding to the position in which the transfer of the reel 30 to a subsequent operating station, such as a stocking unit, takes place.
  • driving means consisting of a drive chain 20 and a plurality of sprockets 29 - preferably connected to a brushless motor 18 and its relevant reducer 19 - to move the carriage 23 from the position of reel 30 formation by winding to the position in which the transfer of the reel 30 to a subsequent operating station, such as a stocking unit, takes place.
  • the carriage 23 is divided into three reciprocating parts, ensuring the locking and unlocking of the winding rod on which the reel 30 is formed: a front peg 14, a rear peg 16 and a braking peg 15.
  • the front peg 14 engages the rod during the changeover of reel's loading/unloading, while the peg 16 engages the rod during the winding.
  • a winder 1 is shown, according to the present invention, exhibiting at least a torsion bar 21 disposed below the winding cylinder 13 which performs function of ensuring a sinchronized motion of both arms 3 and carriages 23.
  • the synchronization function may be achieved by means of suitably brusheless motors associated with each jack 8, and a brushless motor 18 associated with carriage 23.
  • Fig. 5 shows the step in which a reel 30 carried by the carriage 23, and being near to the end of winding, is moved away from the cylinder 13 thereby generating a gap between the same cylinder 13 and the carriage 23.
  • the oscillating arm 11, on which the second rod is mounted moves close to the winding cylinder 13 to "launch" the rod at the appropriate winding speed.
  • Fig. 6 shows a successive operating step in which, after having put the second rod 2 in contact with the winding cylinder 13 to generate the predetermined contact pressure "P", the winding of a fresh reel (30) is started.
  • Fig. 7 shows the step in which the reel 30 in the course of formation is transferred from the oscillating arm 11 to the winding carriage 23.
  • This handover step takes place as a consequence of the approach of second winding rod 2, carrying the fresh reel 30 in the course of formation, to the winding carriage 23.
  • Fig. 8 Shown with reference to Fig. 8 is the final winding step, in which the reel 30 continues to have material wound thereon until its completion on carriage 23 by maintaining the pressure "P" on the cylinder 13.
  • a method for controlling the winding of a reel 30 of web material comprises the steps of:
  • the detection step is performed by one or more load cells 17 responsive to the contact pressure "P" between the reel 30 and the winding cylinder 13.
  • the present invention obtains important advantages.
  • a first advantage lies in the fact that the high rigidity of the rod-holder supports 3, 23 for the movement of the winding rod 2, 31, makes it possible to accurately control, by means of the load cells 17 and data-processing unit, some parameters of basic importance for a successful winding, such as the pressure of contact between the winding cylinder 13 and the reel 30 in the course of formation, and the rate of increase of diameter of reel 30 in the course of formation, for example.
  • the winder 1 according to the present invention therefore, makes it possible to control the above parameters during all the main steps of the winding operation.
  • the load cells 17 allows controlling the pressure "P" between the winding cylinder 13 and the reel 30 in the course of formation when the latter is at the beginning of winding, that is, when the web material begins to be wound up around the second rod 2, as well as when the winding is about to be completed on the rod 31 located on the carriage 23 which moves away from the cylinder 13 to allow the tearing of same material.
