Definitions

  • the present invention relates to a sealing system for containers, in particular of the type which envisages sealing with an aluminum cap.
  • sealing systems of the mouths of the bottles or containers are used immediately after filling in order to guarantee integrity and absence of bacterial contamination. Filling is typically performed in sterile atmosphere.
  • Examples of applications of this type are milk and milk derivatives, fresh fruit juice, isotonic beverages and generally all applications characterized by extreme organoleptic sensitivity and high possibility of perturbation due to uncontrolled environmental aspects, arriving to the most delicate pharmaceutical applications.
  • Sealing systems of this type envisage the welding of an aluminum cap onto the mouth of the container and consist of a plurality of discontinuous steps which generate low productivity and high risk of errors and malfunctions.
  • the plastic-coated aluminum seal is formed by cutting/plastic deformation starting from semi-finished web on reels by means of a plurality of reciprocating and linear movements.
  • the step of forming of the seal or cap is performed in an area outside the controlled atmosphere zone, and then the cap is conveyed into the controlled atmosphere zones by means of a carrying channel, generally located at a greater height so as to exploit the force of gravity to advance the seals.
  • Sterilization means typically of the induced energy type (UV radiations), which guarantee the sterility of both the caps and the inlet air, are arranged along the carrying channel.
  • the caps are positioned on the transiting containers through a release head. Downstream of this equipment there is a machine for thermally welding the seal onto the mouth of the container.
  • the system described above has a number of limitations and inefficiencies which negatively influence production continuity of the system mainly because of the criticality of conveying the caps from the outside into the controlled atmosphere chamber, and very often require restoring operations which may even cause the alteration of the controlled atmosphere. This causes the rejection of considerable amounts of product and the need for various sanitation cycles to restore the correct environmental quality in the controlled atmosphere zone.
  • the problem addressed by the present invention is thus to make available a sealing system of containers which solves the problems inherent to the equipment of the prior art.
  • the invention relates to a system for making and distributing caps or seals on the mouth of a container having the following features:
  • the shearing, forming and depositing process of the cap or seal on the mouth of the container is performed entirely inside the controlled atmosphere chamber
  • the seals or caps are entirely moved by retaining and carrying members, thus preventing steps in which they are subject to freely falling upstream of the releasing point of the cap onto the mouth of the container,
  • sealing material web typically plastic-coated aluminum
  • FIG. 1 is diagrammatic plan view of a container filling and sealing system which comprises the forming equipment according to the present invention
  • FIG. 2 is a diagrammatic view of the forming equipment according to the invention.
  • FIG. 3 is a front view (according to direction A in FIG. 2 ) of the positioning roll according to the invention
  • FIG. 4 is a front section view (according to direction A in FIG. 2 ) of a detail of the cutting roll according to the invention
  • FIG. 5 is a front view (according to direction A in FIG. 2 ) of a detail of the forming roll according to the invention
  • FIG. 6 is a side section view (perpendicular to direction A in FIG. 2 ) of the swinging punch of the forming roll in FIG. 5 .
  • the filling and sealing system of containers according to the present invention comprises a controlled atmosphere chamber 2 , in particular a cleanroom, in which the following are arranged in sequence:
  • a capping unit 8 optionally, a capping unit 8 .
  • the containers, bottles, flasks or the like enter into the controlled atmosphere chamber 2 through a first conveyor 9 and are moved between the various processing unit by means of transfer stars 10 to then be removed from the controlled atmosphere chamber 2 by a second conveyor 11 .
  • the processing units 3 , 4 , 5 , 6 , 7 , 8 , the conveyors 9 , 11 and the transfer stars 10 are of the conventional type and will be selected according to the type of containers and products to be treated.
  • the layout of the filling and sealing system may also be modified to take particular production needs into account.
  • the filling and sealing system 1 further comprises a forming equipment 12 of a cap or seal made of a material, typically plastic-coated aluminum, which is weldable on the mouth of a container.
  • the forming equipment 12 comprises a service portion 12 a outside a controlled atmosphere chamber 2 and an operating portion 12 b within the controlled atmosphere chamber 2 .
  • the service portion 12 a comprises at least one reel 13 , typically two reels 13 so to have a spare for rapidly replacing the finished reel, of sealing material S and a series of return rolls 14 , 14 ′, 14 ′′ for moving the web of sealing material S unwound from the reel 13 .
  • the sealing material S is normally plastic-coated aluminum in form of web.
  • the web of sealing material S is moved by traction, in particular by the cutting roll, as will be described below.
  • the reels 13 are thus provided with a brake system or a servo drive associated with the respective unwinding spindle 16 so as to prevent the uncontrolled unwinding thereof.
  • a suction surface 15 the function of which is to fix the web of material S in position at the time of joining for changing the reel, is arranged downstream of the reel.
  • a buffer chamber 17 having a bottom wall 17 a and side walls 17 b.
  • Vacuum V is applied to the buffer chamber 17 by means of suitable suction means 19 , such as a fan, so as to create a loop A of the web of sealing material S between a first return roll 14 ′ and a second pair of return rolls 14 ′′.
  • the buffer chamber 17 comprises a series of detection sensors 18 , typically photocells, arranged along a side wall 17 b, so as to detect the length L of the loop A between respective return rolls 14 ′, 14 ′′ and the bottom F′ of the loop A.
  • the detection sensors 18 are connected to a command and control unit (not shown), which in turn is connected to the unwinding spindles 16 so as to adjust the extent of the brake or the activity of the servo drives of the spindles 16 as a function of the length L of the loop A. In this manner, both the length L of the loop A in case of possible decelerations or accelerations of the downstream operating steps and the tensioning of the web of sealing material S as determined by the value of the vacuum V in the buffer chamber 17 , can be maintained constant.
  • the service portion 12 a of the equipment 12 comprises a rewinding reel 20 operated by a motorized rewinding spindle 21 , which recovers the scrap tape SF of sealing material S (see the following steps of the process).
  • the controlled atmosphere chamber 2 Downstream of the buffer chamber 17 , the web of sealing material S is introduced into the operating portion 12 b of the equipment 12 , in the controlled atmosphere chamber 2 .
  • the controlled atmosphere chamber 2 comprises a roll inlet port 22 comprising two opposing rolls through which the web of sealing material S passes.
  • the controlled atmosphere chamber 2 comprises a roll outlet port 23 through which the scrap tape SF passes before it is wound on the rewinding spindle 20 . In this manner, the separation between controlled atmosphere chamber 2 and the outside of the equipment (service portion 12 a ) is obtained. An overpressure of air or other sterile gas present in the controlled atmosphere chamber 2 will avoid the introduction of non-sterile air into the operating portion 12 b.
  • sterilization means 24 preferably comprise a tank 25 containing a sterilizing liquid C, e.g. a solution of peracetic acid. Rolls 26 are arranged in the tank 25 so as to create a tortuous path for the web of sealing material S in order to prolong the permanence time thereof in contact with the sterilizing liquid.
  • a sterilizing liquid C e.g. a solution of peracetic acid.
  • the web of sealing material S is then conveyed, by means of appropriate return rolls 27 , through rinsing or activation means 28 , e.g. a series of spray nozzles dispensing sterile water or steam.
  • rinsing or activation means 28 e.g. a series of spray nozzles dispensing sterile water or steam.
  • Sterilization means of different type may be provided, e.g. a UV radiation system, in different embodiments. In such a case, the rinsing or activation means 28 may also be eliminated.
  • a positioning roll 29 is arranged on which the web of sealing material S is made to adhere.
  • the positioning roll 29 is tangential, in the order according to the direction of rotation of the roll, firstly with a cutting roll 30 , adapted to cut a sheet of sealing material S from the web, and then with a forming roll 31 , adapted to shape the cut material S into a cap or seal, e.g. in the characteristic crown shape.
  • the receiving unit 6 which comprises a conveyor having a plurality of plates 33 , each of which holds a container B to be sealed, or alternatively a sliding surface in common to all the containers B to be sealed, is arranged underneath the positioning roll 29 .

  • the sheet of sealing material S (which will later be shaped to provide a seal or cap O) is cut in the tangential point between positioning roll 29 and cutting roll 30 , the sheet remaining adherent to the positioning roll 29 by virtue of the suction, while the scrap tape SF is drawn by the cutting roll 30 , which is motorized, passing between it and a counter-pressure roll 34 , and exits from the controlled atmosphere chamber 2 through the outlet roller door 23 to be rewound on the rewinding reel 20 .
  • the counter-pressure roll 34 swings around a hinge 35 and is pneumatically operated, by means of a pneumatic cylinder 36 , or in other embodiments by means of elastic systems, e.g. spring systems, so as to ensure a predetermined pressure on the cutting roll 30 and thus promote the traction of scrap tape SF.
