Definitions

  • the present invention relates to a rinsing machine for bottles and a method for rinsing bottles.
  • the rinsing machine according to the invention may be a single rinsing machine or a multiple rinsing machine, of the rotary type.
  • a rinsing machine for bottles is inserted into a bottling line and is intended for washing or rinsing bottles before they are filled.
  • a rinsing machine is equipped with at least one rinsing head capable of handling one single bottle at a time.
  • the rinsing machine is called a single rinsing machine if it is equipped with a single rinsing head and is thus capable of processing one bottle at a time, or a multiple rinsing machine if it is equipped with a plurality of rinsing heads and is therefore capable of treating multiple bottles at a time.
  • the machine is of the rotary type with the rinsing heads installed along the periphery of a rotating turret.
  • each rinsing head comprises a gripper that is adapted to grasp the bottle, e.g. by its neck, to rotate it substantially 180° until the mouth of the bottle faces downward above an injection nozzle of a treatment product.
  • the product is projected inside the bottle, and after hitting and wetting the inside wall of the bottle, it exits the upside-down bottle by gravity, falling into a special collection tank arranged under the rinsing head. From such a reservoir, the liquid is, for example, either piped to the drain or conveyed to a recycling circuit. Once the treatment liquid is discharged, the gripper returns the bottle to its normal position.
  • any residual treatment liquid that may remain on the mouth until the bottle is capped would then be trapped between the cap and the mouth.
  • the presence of this residual liquid may create problems relating to bacteriological sterility.
  • each rinsing head with a suction tube adapted to suck the droplets from the mouth as the bottle moves from the upside-down position to the normal position.
  • An alternative solution involves equipping each rinsing head with a compressed air nozzle with which blasts of compressed air are generated that are to be directed onto the mouth.
  • the main object of the present invention is therefore to eliminate all or part of the disadvantages of the aforementioned prior art by providing a rinsing machine for bottles which is capable of significantly reducing the presence of liquid residue on the mouth of the bottle in order to substantially eliminate the risk of wetting the outer surface of the bottle.
  • a further object of the present invention is to provide a rinsing machine for bottles which is easily adaptable to variations in the type of bottle "mouth.”
  • a further object of the present invention is to provide a rinsing machine for bottles which is no more complex in operation than similar machines of a known type.
  • a further object of the present invention is to provide a rinsing machine for bottles which is no more complex in construction than similar machines of a known type.
  • the present invention relates to a rinsing machine for bottles.
  • the rinsing machine according to the invention may be a single rinsing machine or a multiple rinsing machine, of the rotary type.
  • the rinsing machine according to the invention is a multiple, rotary-type rinsing machine.
  • the bottle C will be said to be in the "upright” position when its mouth B is facing upwards and that it is in the "upside-down” position when its mouth B is facing downwards.

  • the bottle manipulator 12 may comprise at least one gripper adapted for grasping a bottle, preferably by its neck.
  • the gripper may be of any type as long as it serves the purpose. The structure, function, and mode of operation of these types of grippers are known per se to those skilled in the art and will therefore not be described here.
  • the means 3 for moving and operating grippers 10 may also be of any type, as long as they serve the purpose.
  • the aforesaid support structure 2 consists of a turret rotating around a machine rotation axis A.
  • the aforesaid means 3 for moving and operating grippers comprise a cam 3 for moving and guiding grippers, which cam extends around said rotating turret and is rotationally fixed.
  • This cam 3 is kinematically connected to each rinsing gripper 10 to be guided and operated during the rotation motion of the turret as a function of the angular position assumed around the machine rotation axis A.
  • said cam 3 for moving and guiding grippers is kinematically connected to the bottle manipulator 12 of each gripper 10 by a cam follower 30.
  • Each rinsing gripper 10 further comprises an injection nozzle 13 that is configured to inject a treatment liquid inside a bottle engaged by the respective bottle manipulator 12 through the mouth of the bottle itself when said manipulator 12 is in the working position, so as to carry out the rinsing of the bottle itself.
  • the nozzle 13 is connected to a supply circuit comprising a tank of treatment liquid and at least one pump.
  • Each rinsing gripper 10 further comprises a collection manifold 14 for collecting the treatment liquid that, after injection, exits the bottle by gravity.
  • each rinsing gripper 10 may comprise suction means 15 for sucking the treatment liquid residues remaining on the bottle, and particularly on the mouth.
  • the collection manifold 14 is a first collection manifold 14:
  • the movement means 16 are configured so that, when said collection manifold 14 is moved, it follows the movement of the manipulator 12 at least for all the positions assumed by the manipulator 12 itself between the working position and a predetermined intermediate position between the working position and the rest position, while remaining fluidically connected to the bottle grasped by the manipulator 12.
  • annular sealing body 142 is provided with a conical conveying portion 143 intended to be sealingly inserted inside the mouth B so as to convey the treatment liquid exiting the bottle directly inside the collection manifold 14.
  • a preferential path is created for discharging the liquid into the manifold, significantly reducing the risk of the liquid running on the outside of the mouth and thus possibly forming a liquid ring on the mouth.
  • the manipulator 12 defines a bottle centering axis X, which in use is aligned with the central axis of the bottle C passing through the mouth B.
  • the movement means 16 of the manifold 14 comprise:
  • the second mechanism 162 makes it possible to:
  • the manifold 14 comprises a main tubular body 144 and a secondary tubular body 145 which is mounted axially floating on the main tubular body 144 and which supports said annular sealing body 142.
  • the bottle manipulator 12 and the manifold 14 are both rotationally connected to said fixing structure 11 around a same rotation axis Y.
  • the first mechanism comprises a first guide cam 161 that is integral in rotation with said manipulator 12 and is kinematically engaged by said manifold 14 to move it in a guided manner, transferring the rotation motion of the manipulator 12 thereto.
  • This first guide cam 161a has:
  • connection point between the circumference arc section 161' and the straight section 161" of said first guide cam 161 defines said predetermined intermediate position.
  • the second mechanism 162 comprises elastic means that are interposed between the main tubular body 144 and the secondary tubular body 145 of said manifold 14 and are configured to impose an axial thrust on said secondary tubular body 145 and on the associated annular sealing body 142 with respect to said main tubular body 144.
  • the movement means 16 of the manifold 14 comprise a second guide cam 163, which is integral to said fixing structure 11 and is engaged by said main tubular body 144.
  • Said second guide cam 163 is shaped to guide the rotation movement of the manifold 14 around said rotation axis Y, in cooperation with the first mechanism 161.
  • the main tubular body 144 of the manifold 14 is guided by said second guide cam 163 when the secondary tubular body 145 engages the straight section 161" of the first guide cam 161.
