Definitions

  • the present invention relates to a semiautomatic foil loading apparatus for use in an aseptic flexible container filling system.
  • Aseptic flexible containers are composed of low linear density polyethylene walls.
  • Their head includes a spout, which is formed of a suitable material, such as microcrack-resistant high density polyethylene, capable of withstanding sterilization treatments with ionizing radiation ( ⁇ rays).
  • a spout which is formed of a suitable material, such as microcrack-resistant high density polyethylene, capable of withstanding sterilization treatments with ionizing radiation ( ⁇ rays).
  • the spout has:
  • the outer face of the collar has such a shape as to be able to hold a standard protection cover.
  • the bag spout is sealed by a circular disk known as foil, which is placed above the collar and heat sealed to the top edge thereof.
  • This foil made from a multilayered material (Nylon, low linear density polyethylene and aluminum) is provided in pre-embossed form. Thus, as the foil is laid on the spout, one part thereof rests on the top end of the collar and another part penetrates into the spout.
  • the bag spout is introduced in the filling head with the foil thereon; the sealer is moved down to pick up the foil, and may undesirably seal it.
  • the sealer is moved away from the spout, steam sterilization of the spout and foil is initiated, whereupon the sealer is lifted and offset, the dispenser moves down and breaks the spout to penetrate into the bag collar, the membrane is thus ruptured and the product can thus be filled.
  • the filling dispenser performs steam cleaning and is lifted up, the sealer is centered again, moves down and heat seals the foil, whereupon the bag is removed.
  • the prior art requires an operator to manually introduce the foil and the spout into the filling head.
  • the object of the present invention is to obviate the above mentioned drawbacks by carrying out the foil loading step out of the filling head, in a safe and easily controllable environment.
  • a first advantage of the inventive apparatus is undoubtedly provided by a quicker foil loading step, which occurs on an interchangeable cup outside the filling head. Such external loading step provides easier positioning.
  • One advantage consists in accurate positioning of the foil (whether or not embossed) on the spout, which is reflected in an effective sealing effect between the foil and the top end of the collar, and adequate product preservation.
  • Pre-embossed foils may have several different diameters.
  • a further important advantage provided by the apparatus of the invention is the possibility of simplifying the geometry of the foils, thereby affording further cost reduction.
  • Another important advantage is the prevention of any risk of sealing the foil to the spout during the foil picking up step prior to filling, which would involve the loss of sterile bag and recovery of the product in the bag.
  • numeral 1 designates a means for loading a foil (51), which is composed of two parts: an arm with an interchangeable foil holding cup 2 on its free end; a second part 1b, pivotally mounted to a vertical pin 5 (coinciding with the rod of a double acting piston 10), and connected by a small arm to the rod 6a of a double acting piston 6.
  • the rod 6a and the small arm of 1b are hinged in 7.
  • the skirt of the piston 6 is in turn hinged in 9 to a vertical pin supported by the frame of the filling head (Fig. 3 is a sectional view of the hinge 9).
  • a screw 8 is provided in the rod 6a of the piston 6, for adjusting the limit stop of the piston.
  • the interchangeable cup 2 is also composed of two parts: an upper part 2a having a circular foil holding recess 3; a lower part 2b with a connection for a vacuum source, connected to the recess 3 by a hole 4.
  • a second piston 10 moves the arm 1a in a vertical direction and transfers the foil in the filling head against the sealer, which is shown by thin lines and designated by 100.
  • Numeral 11 designates a second limit stop adjustment screw which adjusts the vertical lift of the loading means 1.
  • the pneumatic pistons 6 and 10 constitute the means for transferring the loading means and thus the foil into the filling head.
  • the machine operator places the foil (51) in the circular recess 3 of the cup 2 at the free end of the arm.
  • Vacuum is then created in the recess 3 during transfer of the coil, to ensure that the foil is always correctly positioned until it is introduced in the filling head.
  • the operator initiates the foil transfer cycle: once the arm is moved to its position beneath the filling head by the rotary motion given by the piston 6, the piston 10 moves the arm 1a vertically and thereby introduces the foil in the head. Now, by releasing the vacuum in the recess 3 of the cup 2, the heat-sealing head can pick up the foil by means of a suction system. Then, the loading means may move back outside the filling head.
  • both the spout and the foil are sterilized with steam, whereupon the dispenser penetrates the bag collar, the membrane is ruptured and filling occurs.
  • the filling dispenser is lifted up, the foil is placed in its position and heat-sealed to the top end of the spout collar and the bag is removed.
  • the novel apparatus will be appreciated for its versatility, which derives from the possibility of changing the cup 2 according to the foil to be used (different foil types are provided depending on the type of spout on the container), provided that the two limit stop adjustment screws 8 and 11 and the hinge 9 are also adjusted.
  • flat foils (52) may be used instead of the above embossed foils (see Fig. 6).
  • the cup 2 has a recess 3 with a slight undercut adapted for holding the flat foil.
  • the rotation of the cup-transferring arm may be obtained using pneumatic motors or other systems, and the lifting motion may be obtained by other systems without departure from the scope as defined in the annexed claims.
