Definitions

  • Roll-fed filling machines also referred to as packaging machines
  • packaging machines are well known within the field of liquid food packaging.
  • One example of such machines is the Tetra Pak ® A3 machine, which receives a reel of carton-based packaging material and, via a pipe, a liquid food product. The machine operates to create individual packages that are made from the packaging material and filled with the liquid food product.
  • machines like this unwind the packaging material from the reel. After being sterilized, e.g., by using hydrogen peroxide, the packaging material is continuously formed into a tube. While feeding the tube in a vertical position, an upper end of the tube is filled with food product, e.g., milk, via a product filling pipe that extends into an interior of the tube from above. By continuously and transversally sealing and cutting the tube at its lower end, packages filled with food product are formed at spectacular speeds.
  • food product e.g., milk
  • the sealing jaw has two heating elements which are used to create two seals in the tube, by partially melting the "pinched" surfaces of the packaging material such that the material is joined at the seals.
  • the knife is moved out from a position between the heating elements and pushed through the tube in between the two seals, thereby separating an individual package from the lowermost part of the tube.
  • the knife is thereafter retracted into the sealing jaw and the two jaws are moved away from the tube.
  • the jaws move along tracks that are parallel to the tube and eventually perform the same operation again to create another package from the tube.
  • Multiple pairs of sealing jaws and pressure jaws move along the tracks to perform this operation, thereby continuously creating individual, product-filled packages from the tube.
  • the knife is advantageous in that the protrusion enables a sensor unit to detect if the knife is not properly retracted after it has cut through a tube-shaped body. Faulty retraction can happen for many reasons, for example if the cutting unit malfunction. Other reasons for improper retraction could be that the attachment portion of the knife is broken, leading to misplacement of the knife relative the cutting unit, which in turn causes faulty retraction of the knife. Faulty retraction of the knife can lead to undesired holes or damages to the tube-shaped body, for example in a configuration where the cutting unit moves the knife in parallel with the tube-shaped body before the knife is moved to cut through the tube-shaped body.
  • the knife is thereby advantageous in that it is possible to provide for that less damage happens to the tube-shaped body. This means that the numbers of individual packages which are defect is reduced.
  • a filling machine for filling and sealing packages.
  • the filling machine comprises a longitudinal sealing unit arranged to form a tube-shaped body from a web of packaging material, a product filling pipe arranged to fill food product into the tube-shaped body, and a cutting unit to which a knife is attached, the cutting unit being arranged to transversally seal and cut the tube-shaped body for forming individual packages filled with the food product.
  • the cutting unit is doing this by heat sealing the tube-shaped body, and moving the knife in a direction parallel to a cutting direction of the knife, from a retracted position, to a cutting position and back to the retracted position.
  • the filling machine has a sensor unit configured to interact with a protrusion of the knife if the knife is not moved back from the cutting position to the retracted position.
  • the knife attached to the cutting unit is a knife according to the first aspect, including any embodiments of this knife.
  • a method for filling and sealing a package.
  • the method comprises forming a tube-shaped body from a web of packaging material, filling food product into the tube-shaped body, and transversally sealing and cutting the tube-shaped body for forming individual packages filled with the food product.
  • the cutting comprises cutting the tube-shaped body with a knife according to the first aspect.
  • the filling machine and the method may use any embodiment of the knife according to the first aspect. They have the same advantages as provided by the knife.
  • a knife is provided for being attached to a filling machine according the second aspect, where the attached knife is a knife according to the first aspect.
  • a knife is provided for being used in the method according to the third aspect, where the knife is a knife according to the first aspect.
  • a filling machine 300 for filling and sealing packages 203 is illustrated.
  • a web 201 of packaging material 200 is provided in form of a packaging material strip that is rolled of a reel of packaging material.
  • the packaging material 200 has a carton or fiber-based support layer and, on at least one side of the support layer, a polymer layer or another layer that it suitable for heat sealing.
  • a longitudinal sealing unit 302 the web 201 is formed into a tube-shaped body 202, also referred to as a tube.
  • a tube 202 is continuously formed.
  • the tube 202 can be directed by a tube guiding unit 306 into a cutting unit 310.
  • the cutting unit 310 has a cutting jaw 311, also referred to as a heating jaw or a sealing jaw, and a pressure jaw 312 that are mounted on a respective side of vertical travelling path of the tube 202.
  • the jaws 311, 312 are movable towards each other such that they press inner surfaces of the tube 202 towards each other, thereby sealing off the tube 202.
  • the cutting jaw 311 has two heating elements 313, 314 which are used to create two seals 204, 205 in the tube 202. This may be done by partially melting at least one inner surface of the packaging material 200 at the location where the tube 202 it is sealed off, i.e. where it is pressed together by the jaws 311, 312.
  • a knife 100 is moved out from a position 315, usually formed as a slot, between the heating elements 313, 314.
  • the knife 100 is moved in a direction D parallel to a cutting direction C of the knife 100, from a retracted position to a cutting position.
  • an edge of the knife 100 is located into a groove 316 in the pressure jaw 312.
  • the knife has then cut through the tube 202. This separates a lower part of the tube 202 from the rest of the tube 202. The separated, lower part then forms an individual package 203.
  • the knife 100 is moved back to the retracted position in between the heating elements 313, 314, such that it is again located in the slot 315. Simultaneously the jaws 311, 312 are moved away from each other.
  • the heating elements 313, 314 does not have to be arranged on the same jaw as the knife 100.
  • jaw that holds the heating elements 313, 314 may be referred to as a heating jaw.
  • the groove into which the knife 100 extends when cutting through the tube 202 is then located in the heating jaw between the heating elements.
  • the jaw that holds the knife 100 may generally be referred to as a cutting jaw.
  • the cutting jaw may or may not have heating elements.
  • the jaw that is opposite the cutting jaw may generally be referred to as the opposite jaw.
  • the opposite jaw may or may not have heating elements.
  • the tracks 317, 318 have a respective portion that is parallel to the tube 202, move with the same speed as the tube 202 and returns the jaws 311, 312 to the tube 202 such that the same sealing and cutting operation can be performed again to create another package from the tube 202.
  • Multiple pairs of sealing jaws and pressure jaws move along the tracks 317, 318 to perform this operation, thereby continuously creating individual, product-filled packages from the tube 202.
  • Fig. 6 shows section A of Fig. 5 in enlargement
  • the knife 100 is located in a cutting jaw 311 and the heating elements 313, 314 are located in the opposite jaw which here forms a heating jaw 312.
  • the major part of the knife 100 is hidden behind a cover 322.
  • the cover 322 has a frontmost cover part 323 (see also Fig. 8 ) and a rearmost cover part 324 (see Fig. 7 ), which are arranged on a respective side of the knife 100.
  • One heating element 313 of the two heating elements 313, 314 is via attachment means, here exemplified with bolts 325, connected to the heating jaw 312.
  • the other heating element 314 is connected to the heating jaw 312 in a similar manner, in Fig. 5 and 6 located behind the illustrated heating element 313.
  • the cutting jaw 311 is illustrated with the knife 100 in the retracted position P1.
  • no part of a cutting edge 102 of the knife 100 extends beyond the cover 322 of the cutting jaw 311, as seen in the cutting direction C of the knife 100.
  • the frontmost cover part 323 has been removed for illustrative purpose, such that the rearmost cover part 324 can be seen.
  • the knife 100 When the knife 100 is in the retracted position P1, it may then be retracted such that no part of the cutting edge 102 extends beyond an outermost surface 320 of the cutting jaw 311, as seen in the cutting direction C of the knife 100.
