Definitions

  • the present invention relates to a winder for film of plastic material.
  • Winders are generally used for winding material in films, webs or layers on cores so as to obtain rolls of sheet material suitable for sale. For this reason winders are generally positioned downstream of an extrusion assembly so as to wind the film coming out of an extrusion head.
  • the turret winder also known as carrousel or revolver winder, has a rotating cage with horizontal axis which supports peripherally at least two spindles or mandrels (one in a loading position and the other in a winding position) whereon the cores for winding are inserted.
  • the spindle When the spindle is in the winding position, it is rotated around its own axis so as to wind the film onto the cores in order to form the rolls.
  • a pressure roller or compactor roller is in contact with the roll being formed, so as to control the pressure on the film, preventing air from entering the gaps between the turns of the film which is wound on the roll.
  • the pressure roller moves so as to adapt to the growth in diameter of the roll being formed.
  • the changeover step takes place wherein the cage is rotated around its own axis and a new spindle, preloaded with empty cores, moves from the loading position to the winding position, while the spindle with the completed rolls moves from the winding position to an unloading position wherein the rolls are ready to be unloaded from the winder.
  • the pressure roller moves away from the almost formed rolls and the film is cut so as to be wound on the new cores.
  • This turret winder has the disadvantage that, during the changeover step, the pressure roller detaches from the rolls being formed, and consequently the pressure on the last turns of the roll is not controlled, with the result of having rolls with film wound irregularly, jeopardising the actual quality of the film.
  • the turret winder has disadvantages from the viewpoint of production rate which cannot be increased beyond a certain limit.
  • the critical speed is reached at which the spindle starts to vibrate.
  • the turret winder has constructional and structural difficulties due to the high inertial masses to be moved during rotation of the cage for the spindle change. Furthermore the turret winder is weighed down by the use of motors electrified by a brush collector and mounted integrally on the cage for rotation of the spindle during winding. Moreover the use of other types of motors is inadequate due to the wiring to the relative drives which would obstruct rotation of the cage.
  • the contact winder has a motorised drum rotating around its own horizontal axis.
  • a spindle with the cores preloaded is taken from a loading position to a winding position wherein the cores are in contact with the drum which, by rotating, causes winding of the film on the cores for the formation of the rolls.
  • the drum remains fixed in position and the spindle is supported by a mobile support so as to move into position to adjust to the increase in diameter of the roll being formed.
  • the spindle is moved into a roll unloading position and a new spindle with preloaded cores is taken into the winding position.
  • the contact winder has the main disadvantage of not allowing adequate control of the pressure on the roll during winding.
  • the changeover step when a new spindle is taken from the loading position to the winding position, there is no control of pressure on the roll. Consequently the first turns of the roll risk having imperfections which will affect the entire roll.
  • An object of the present invention is to eliminate the disadvantages of the prior art, by providing a winder for film of plastic material which is extremely efficient and capable of allowing a high production speed.
  • Another object of the present invention is to provide such a winder for film of plastic material which is capable of guaranteeing high quality of the rolls produced.
  • Yet another object of the present invention is to provide such a winder for film of plastic material which has a simple and compact structure, at the same time stable and secure.
  • the winder for film of plastic material according to the invention comprises:
  • the spindle support means comprise at least two cradles mounted fixed in the shoulders of the frame of the machine, and another three cradles (two lateral and one central) positioned on respective connecting-rods, and the pressure control means comprise at least one roller mounted movably so as to follow the increase in diameter of the roll being formed in the winding zone.
  • This type of solution has the advantage of having a spindle rotatably mounted in the shoulders of the frame of the machine and therefore maintained fixed in position, throughout winding.
  • the pressure control means move during winding to adjust to the growth in diameter of the rolls.
  • This solution not only allows high stabilisation of the spindle so as to have high speeds of rotation of the spindle during winding, but also allows the pressure on the roll to be controlled throughout the winding phase.
  • the movement connecting-rods also allow a reduced cycle time to be obtained and in particular a cycle time of less than 30 seconds.
  • the winder 1 comprises a main frame formed by a base integral with the ground and two sides or shoulders 2.
  • the spreading roller 4 is capable of producing forces transverse to the film 3 to eliminate any longitudinal creases.
  • the film 3 is then fed by motorised drive rollers 5A and 5B and guided by idle rollers 6A and 6B.
  • respective pressure rollers 7A, 7B are provided, mounted on oscillating arms to regulate the drawing or pull on the film 3.
  • the film 3 leaving the idle roller 6B is wound around cores 10 (Fig. 3) supported by a spindle 8.
  • the spindle 8 is rotatably supported by the frame of the machine in a working or winding position. As shown better in Figs. 2 and 3, the spindle 8 in the working position is supported at its ends by cradles 9 integral with the shoulders or sides 2 of the frame of the machine. Each cradle 9 has a pair of teeth 16 suitable for retaining the spindle 8 in the winding position.
  • a first compactor roller 11 is provided, rotatably mounted on a pair of arms 12 hinged to the shoulders 2 of the machine.
  • the arm 12 is moved by a linear actuator 13 hinged to the frame 2 of the machine.
  • the linear actuator 13 pushes the arm 12 towards the cores 10 supported by the spindle 8 in the working position, so that the first compactor roller 11 exerts a pressure on the web 3 of the roll being formed, avoiding the formation of air in the turns of the roll.
  • a pressure roller 14 is mounted which presses on the compactor roller 11 to stretch out the web 3 which passes in the gap between the pressure roller 14 and the first compactor roller 11 before winding in the cores 10 supported by the spindle in the winding zone.
  • the unloading connecting-rod assembly 20 comprises three arms (two lateral arms 21 and a central arm 21') mounted on a shaft 22 arranged transversely on the sides 2 of the frame of the machine and rotatably mounted around its own axis.
  • a cradle 23 is provided, suitable for holding a spindle.
  • a tooth 24 is mounted, suitable for retaining the spindle in the cradle 23.
  • the shaft 22 of the unloading connecting-rod assembly is driven by a motor drive so as to rotate around its own axis.
  • the unloading connecting-rod assembly 20 can move from a working position wherein the cradles 23 act as additional support for the spindle 8 in winding position, to an unloading position wherein it unloads the spindle 8, with the relative rolls formed, into a magazine 60 which is to be described in detail hereinbelow.
  • the spindle 8 is retained by the teeth 24 in the cradles 23 of the unloading connecting-rod assembly 20.
  • the spindle 8 when the spindle 8 is in the working position, the unloading connecting-rod assembly 20 is also in the working position.
  • the two lateral arms 21 support the end parts of the spindle 8 and the central arm 21' supports the central part of the spindle 8.
  • the spindle 8 is supported on five support cradles, that is to say the two cradles 9 of the shoulders 2 of the frame of the machine and the three cradles 23 of the unloading connecting-rod assembly 20.
  • the spindle 8 is highly stabilised and therefore its flexural critical speed at which vibrations are triggered is raised. Consequently, the spindle 8, with a minimal working length of 2 metres, can work at high rotation speeds with the possibility of achieving winding of the web 3 at a rate of approximately 800 m per minute.
  • the unloading connecting-rod assembly 20 also has a second compactor roller 25.
  • the second compactor roller 25 is rotatably mounted on a slide 26.
  • the slide 26 is slidingly mounted on longitudinal guides 27 provided on the arms 21 of the unloading connecting-rod assembly. In this way the second compactor roller 25 can be moved into position by translation of the slide 26, to adapt to the growth in diameter of the roll 80 being formed and to control the pressure on the roll 80 throughout the changeover and unloading steps.
  • the second compactor roller 25 has a brake 28 to stop its rotation and therefore rotation of the roll 80 when winding has been completed.
  • a cutting assembly 50 is provided, slidingly mounted on the shoulders 2 of the frame of the machine. In this way the cutting assembly 50 can move from a lowered rest position to a raised cutting position wherein it performs transverse cutting of the web 3.
  • the cutting assembly 50 has a cutting blade 51 for performing transverse cutting of the film 3, once a roll 80 has been completed.
  • the cutting assembly 50 also comprises an electrostatic bar 52 suitable for generating an electrical field for causing adhesion of the cut film on the new cores for winding. In this way the edge of the cut film adheres to the new cores whereon it has to be wound without the need to use glue or the like.
  • a feed connecting-rod assembly 30 is provided.
  • the feed connecting-rod assembly 30 comprises two arms 31 mounted at the ends of a shaft 32 arranged coaxially inside the shaft 22 of the unloading connecting-rod assembly 20.
