Definitions

  • the present invention refers to an automatic rewinding machine for winding film, in particular a film of flexible plastic material, onto cores supported by a mandrel so as to create rolls of film of plastic material ready to be put on sale.
  • the present invention further refers to a method for automatic production of rolls of film of plastic material.
  • All rewinding machines if provided with complete automation, allow a formed roll of a pre-established length to be deposited at the exit, without stopping the production process, precisely re-positioning a new core for winding of a new roll. However, in any case, it is the operator's task to reload the rewinding machine with new cores for winding, each time a roll change is carried out once the pre-established wound length has been reached.
  • the rewinders are disposed downstream of extruders or calenders and therefore operate as terminal machines in the production process of thermoplastic films. In this case the absolute continuity of the production process must be ensured.
  • rewinders are provided with magazines consisting of chains with couplers/hooks that support two or more mandrels already coupled to the cores to be wound so as to allow the process a longer autonomy, without the immediate intervention of the operator at each roll change.
  • dedicated anthropomorphic robots are applied, which in any case are separate and independent from the machine. Said robots carry out the operations that are normally carried out by the operator, that is to say removal of the mandrel from the cores of the formed rolls, reloading of the cores onto the mandrel and re-placing on the feeder of the machine of the mandrel, with the relative cores for winding inserted.
  • WO 00/61 480 discloses an apparatus and a method of preparing winding mandrels with corresponding tubular cores fitted on them, the method comprising the steps of:
  • the object of the present invention is to overcome the drawbacks of the prior art, providing a rewinding machine for flexible film of plastic material that is fully automatic, able to eliminate the operations of human intervention and able to guarantee a high production cycle speed.
  • Another object of the present invention is to provide such a rewinding machine that is economical, of simple construction, and in which the moving parts and dimensions are reduced to a minimum.
  • Another object of the present invention is to provide such a rewinding machine that is reliable, functional and versatile.
  • Another object of the present invention is to provide a method of producing rolls of film of plastic material that is fully automatic and able to avoid human intervention.
  • the automatic rewinder comprises:
  • the rewinder according to the invention can work automatically without human intervention.
  • the mandrel loading/unloading device is responsible for inserting the mandrel into the cores fed from the magazine to the rewinder to be able to begin the winding cycle and for removing the mandrel from the cores of the formed rolls on completion of the winding cycle.
  • the automatic rewinding device according to the invention denoted as a whole by reference numeral 1, is described with the aid of the figures. Further on, even if some elements of the machine are denoted singly, it is to be understood that they are arranged in pairs, one on each side of the machine.
  • the rewinder 1 comprises a main frame 2 whereon idle rollers 3a, 3b, 3c, 3d and 3e are mounted which guide a film of plastic material 4 (shown with a dashed and dotted line) toward a drive drum 5 disposed in a central part of the machine 1.
  • the drive drum 5 is mounted in such a manner that its side surface comes into contact with the side surface of a roll 6 of film being formed, disposed in the front part of the machine.
  • a pressure roller rotatably mounted on an arm 21 hinged to the frame 2 of the machine acts on the drum 5.
  • the arm 21 of the presser roller 20 is driven by a linear actuator 22 the piston of which is hinged in the central part of the arm 21.
  • a pressure roller 20' rotatably mounted on an arm 21' hinged to the frame of the machine and driven by a linear actuator 22' also acts on the idle roller 3c.
  • a cutting device 60 provided with a cutting blade 61 for cutting of the film 4 is provided beneath the drum 5.
  • the cutting device 60 is hinged to the frame 2 of the machine to be able to pass from a resting position beneath the drum 5, as shown in Figure 1, wherein it does not interfere with the film 4, to a cutting position, above the drum 5 and near the roll 6, to cut the web 4 once the roll 6 has been completed.
  • the roll 6 is formed by the film 4 which winds around a core 9 supported by a mandrel 8 disposed in the winding position.
  • the mandrel 8 when it is in the winding position, is rotatably mounted around its own axis. At each end, the mandrel 8 is supported by a cradle 7.
  • the cradle 7 has a tooth 10 to clamp or release the mandrel 8.
  • the tooth 10 is controlled by a linear actuator 11 mounted on the cradle 7.
  • the cradle 7 is driven by means of a lever system comprising two arms 12 and 13 controlled by a linear actuator 14.
  • the first arm 12 has one end hinged to the cradle 7 and the other end hinged to one end of the second arm 13.
  • the other end of the second arm 13 is hinged to the frame 2 of the machine.
  • the piston of the linear actuator 14 is hinged in an intermediate position of the second arm 13.
  • the linear actuator 14 is supported by the machine frame.
  • An unloading support 15 which moves vertically along a vertical guide 16 acts beneath the cradle 7.
  • the unloading support 15 serves to receive the formed roll 6 and bring it to the height of a slide 17 for unloading thereof.
  • the unloading support 15 also has the possibility of turning around a pivot axis to tip the roll 6 toward the slide 17.
  • the slide 17 is disposed downstream of the machine frame 2.
  • a first lever 30 having a cradle-shaped free end 31 with upward facing concavity is hinged in the rear part of the machine frame 2, at a point of fulcrum 32.
  • the cradle 31 of the lever 30 is situated above the winding drum 5 and the lever 30 is driven in rotation around its fulcrum 32 by actuator means not shown.
  • a second lever 40 that has a telescopic coupling controlled by a linear actuator to be able to be adjusted in length is hinged beneath the winding drum 5, in a point of fulcrum 42.
  • the telescopic lever 40 bears at one end a cradle 41 with a downward facing concavity.
  • a loading support 50 that protrudes horizontally forward from the upper part of the frame 2 is provided in the upper part of the frame 12 of the machine.
  • the loading support 50 has in its front end a cradle 51 with upward facing concavity, to receive one or more cores 9 intended to be wound by the plastic film to form a roll.
  • the loading support 50 is driven in horizontal translation by a linear actuator 52 acting in a horizontal direction.
  • a gluing device 53 which has a glue sprayer and a drive roller 54 is provided in the upper part of the frame 2 above the loading support 50.
  • a loading/unloading device for mandrels denoted as a whole by reference numeral 100, will now be described with reference to Figures 16, 17 18.
  • the loading/unloading device 100 is disposed alongside a side of the rewinder 1.
  • the loading/unloading device 100 comprises a fixed base frame 101 whereon is mounted a movable frame 102 which can translate horizontally, in a longitudinal direction, from a retracted mandrel loading position to an extended mandrel unloading position.
  • the movable frame 102 is mounted on wheels 103 sliding on respective guides provided in the fixed frame 101.
  • a carriage 104 that defines a horizontal plane vertically translatable on a movable frame from a raised mandrel loading position to a lowered mandrel unloading position is mounted on the movable frame 102.
  • Rollers 105 with a longitudinal axis with respect to the rewinding machine are mounted on the carriage 104 to convey the mandrels 8 transversely from the loading/unloading device 100 to the rewinder 1 and from the rewinder 1 to the loading/unloading device 100.
  • Chain carriers 110 able to convey the cores 9 from a magazine toward the rewinding machine are provided upstream of the loading/unloading device 100.
  • the loading support 50 mounted in the upper part of the frame 2 of the rewinding machine is disposed in its retracted position ready to receive the cores 9 coming from the chain carrier 110.
  • a pusher 111 is responsible for pushing the cores 9 into the cradle 51 of the loading support 50.
  • the movable frame 102 of the loading/unloading device 100 is in its retracted position.
  • the support 50 is made to advance into its advanced position. As shown in Figure 20, in this situation the carriage 104 of the loading/unloading device is in its raised position and supports on the rollers 105 a mandrel 8' which is coaxial with the cores 9 held in the cradle 51.
  • the mandrel 8' comprises an expansion system. That is to say, when pressurized air is blown inside the mandrel 8', it expands increasing in diameter, whereas when the air is let out, the mandrel 8' decreases in diameter, being in its unexpanded state.
  • the mandrel 8' in its unexpanded state is pushed transversally on the carriage 104 so as to enter into the cores 9 disposed in the cradle 51.
  • pressurized air is blown thereinto so as to cause expansion thereof and thus gripping of the cores which must be sent for winding.
  • the cores are initially loaded by the chain drive 110 to the loading support 50 which is in its retracted position.
  • the loading support 50 is made to translate horizontally in the direction of the arrow F1 to come into its forward position.
  • the mandrel 8' is inserted inside the cores 9 supported by the loading support 50 and the mandrel 8' is then inflated to increase in diameter and adhere to the cores 9.
  • the first lever 30 is operated upward in the direction of the arrow F2, rotating around its fulcrum 32.
  • the cradle 31 of the lever 30 goes onto the end of the mandrel 8' and raises it, thus raising the cores 9 from the cradle 51 of the loading support 50.
  • the cores 9 thus arrive beneath the gluing device 53.
  • the mandrel 8' is rotated and glue is thus sprayed evenly with the glue on the surface of the cores 9 to allow the film 4 to adhere.
  • the linear actuator 22 is operated to move the presser roller 20 away from the drum 5, so as to allow the passage of the cutting device 60.
  • the cutting device 60 is then rotated around its fulcrum to bring it into the cutting position above the drum 5 and near the formed roll 6.
  • the linear actuator 22 is operated to bring the pressure roller 20 into contact with the drum 5.
  • the first lever 30 is subsequently lowered to bring the mandrel 8' with the cores 9 above the drum 5
  • the second telescopic lever 40 is rotated counterclockwise to bring its cradle 41 above the mandrel 8' and the loading support 50 is withdrawn to return it to its core loading position.
  • the telescopic lever 40 is subsequently lowered so that the cradle 41 engages above the end of the mandrel 8'.
  • the linear actuator 14 is operated to withdraw the cradle 7 in the horizontal direction of the arrow F4 to dispose it in the working position near the drum 5.
