Definitions

  • P45096PC00 1 Cutting device and manufacturing table The present invention relates to a cutting device for manufacturing a fiber-based casing and a manufacturing table comprising a cutting device for manufacturing a fiber-based casing according to the preamble of the independent claims.
  • Different containers for receiving liquid are known from the prior art. For example, glass bottles or plastic bottles for holding beverages have become known. Containers made from fiber-based material have also been proposed. A fiber-based container was proposed in WO 2012/139590 A1. To produce this container, so-called pulp is introduced into a mold and pressed against a corresponding wall with a flexible balloon and compressed accordingly. Pulp is a mixture of fibers and water, in particular natural fibers such as hemp fibres, cellulose fibers or flax fibers or a mixture thereof.
  • the pulp has additives, as known for example from PCT/EP2019/076839, which improve hardening of the compressed pulp or influence the later appearance or generally change the properties of the pulp or the later container .
  • these containers there is a risk that the liquid stored in the container will soften them and cause them to leak, for example, or that substances will diffuse out of the container into the liquid.
  • the fibre-based container thus only provides a cover for a thin-walled plastic container.
  • Such a combination has become known from WO 2018/167192 A1.
  • a fibre-based casing is understood to mean an object into which a further object, for example a plastic container, can be introduced.
  • a fiber-based container is understood to mean a container into which a substance, for example a liquid, can be introduced directly.
  • a fiber-based container typically has a base, a container body and a container neck which is followed by the container opening.
  • a fiber-based casing can also have the aforementioned elements, but this is not mandatory.
  • a fibre-based casing can also, for example, only be tubular and have two openings. It is conceivable that a container to be placed in this cover protrudes from the fibre-based cover both with its base and with its container neck. With regard to an opening to be made up, container openings and openings on tubular ends of a casing are therefore included.
  • a cutting device for making up a fiber-based casing, in particular a fiber-based container, has a first mandrel which can be rotated about an axis of rotation and on which the fiber-based casing can be arranged. Furthermore, the cutting device has a knife which can be rotated about an axis of rotation.
  • the axis of rotation of the first mandrel and the axis of rotation of the knife are arranged adjacent to one another, in particular at an angle of less than 10° to one another, preferably less than 5° to one another, preferably parallel to one another. It goes without saying that the knife is arranged opposite the mandrel in the direction of one of the axes of rotation, ie along the axis of rotation.
  • the mandrel is preferably essentially circular-cylindrical. However, in the direction opposite to a receiving direction of the fiber-based casing, the mandrel can also be at least partially conical in order to facilitate the introduction of the mandrel into the fiber-based casing or the application of the casing to the first mandrel.
  • the take-up direction of the fiber-based casing is the direction in which the fiber-based casing must be moved in order to place it on the mandrel. This arrangement makes it possible for the knife and the mandrel to roll onto one another and thus carry out a cutting movement.
  • this makes it possible to separate a fiber-based casing that is arranged between the mandrel and the knife and to create a defined cutting edge on the fiber-based casing.
  • adjacent to one another means that the axes of rotation essentially run in the same direction.
  • the mandrel described here provision can be made for this mandrel to be designed in such a way that it has a variable diameter.
  • the mandrel can be designed, for example, as a spreader with radially movable segments or sectors.
  • Such a rotation allows a complete circumference of the fiber-based casing to be guided past a specific position, in particular at the position at which the rotatable knife engages.
  • this P45096PC00 5 enables very gentle cutting of the fibre-based casing. Provision can be made for the knife to be mounted so that it can rotate freely and can be driven or is driven by contact with the mandrel or a fiber-based sleeve arranged on the mandrel.
  • This passive driving of the knife ensures that no relative movements take place between the knife and the respective surface to be severed, since this is neglected due to the friction of the knife on the mandrel or on the fiber-based casing to be cut of slippage, is driven exactly with the peripheral speed of the fiber-based casing and thus the peripheral speed of the fiber-based casing and the peripheral speed of the knife match.
  • the tearing of fibers due to a speed difference between the knife and the surface of the fiber-based casing is reduced.
  • provision can be made for the knife to have a drive device. Accordingly, the mandrel and the knife can be driven at the same time.
  • the rotatable blade is preferably arranged to be displaceable relative to the first mandrel in such a way that a distance between the axis of rotation of the first mandrel and the axis of rotation of the blade can be set.
  • the mandrel can thus, in particular together with its drive device, be stationary, for example on a finishing table P45096PC00 6 can be arranged. This makes it possible for the knife to be spaced apart from the mandrel in order to apply the fiber-based casing to the mandrel.
  • the knife is arranged on a carriage or on a pivotable console.
  • the arrangement on a carriage makes it possible to feed the knife in a linear movement to or from the mandrel.
  • the alternative arrangement on a swiveling console allows the knife to be fed in or spaced away from the mandrel with a swiveling movement.
  • the carriage can be designed in such a way that at least a slight pivoting is possible for centering the knife and/or for compensating for tolerances of the fiber-based casing to be cut.
  • prestressing elements can be provided on the carriage.
  • the knife is located in a clear space in front of the mandrel and is moved away from the mandrel by hitting the mandrel or a fiber-based sheath according to its diameter, the knife being driven by the mandrel at the same time and the fiber-based shell is separated.
  • the cutting device can have a second mandrel which can be rotated about an axis of rotation and on which a further fiber-based casing can be arranged.
  • the axis of rotation of the second mandrel and the axis of rotation of the knife are arranged adjacent to one another, in particular at an angle of less than 10° to one another, preferably less than 5° to one another, preferably parallel to one another.
  • P45096PC00 7 By arranging a second mandrel, two fibre-based casings can be cut together with a single knife at the same time.
  • the second mandrel may include a drive device.
  • a fiber-based casing applied to the second mandrel can be rotated together with the second mandrel by the drive device. Such a rotation allows a complete circumference of the fiber-based casing to be guided past a specific position, in particular at the position at which the rotatable knife acts.
  • the first mandrel and the second mandrel preferably have a common drive device. This ensures that both mandrels and thus both fiber-based casings applied to the respective mandrel have the same peripheral speed and thus the same peripheral speed.
  • the knife is arranged on a turntable for centering between the first mandrel and the second mandrel.
  • a pivot point of the turntable is arranged in the area of an axis of symmetry between the two mandrels, and this area can extend on both sides of the axis of symmetry up to the respective mandrel.
  • a spring is preloaded in each of the two directions of rotation or pivoting, which pushes the knife and the turntable into a neutral position.
  • the neutral position corresponds to an alignment of the blade and the turntable on the axis of symmetry.
  • a diameter of the first mandrel and optionally of the second mandrel can each be larger than an inner diameter of the fiber-based casing that is to be applied to the respective mandrel.
  • Such a design enables the fiber-based casing to be held on the respective mandrel without the need for additional holding elements.
  • the fiber-based sleeve is thus held on the respective mandrel simply by a clamping effect.
  • the mandrel is designed with a variable diameter, it can be provided that a first diameter is smaller than an inner diameter of the fiber-based sheath and a P45096PC00 9 second diameter larger than an inner diameter of the fiber based sheath.
  • the cutting device can have one or more stripping devices for stripping off a severed section of the fiber-based casing. These are arranged in a receiving direction after the knife on the first mandrel and, if necessary, on the second mandrel.
  • a fan nozzle can be arranged on the cutting device per mandrel in a receiving direction in front of the knife, in particular below the respective mandrel.
  • An arrangement below the respective mandrel means here that a nozzle opening of the fan nozzle is arranged in front of the mandrel in the receiving direction, but at a radial distance from the mandrel so that the fan nozzle does not collide with a fiber-based casing arranged on the respective mandrel.
  • the fan nozzle makes it possible to blow a cut-off section, which is stripped off the respective mandrel, out of a working space in a desired direction in order to collect it, for example, in a corresponding container.
  • the first and/or the second mandrel can each have an elastic, in particular cut-resistant, coating, in particular a plastic coating. This can be in the form of polyester urethane rubber, for example.
  • a coating can delay excessive wear and/or blunting of the knife.
  • Each mandrel may have a groove shaped to match the cutting edge of the knife.
  • the groove is designed in such a way that the blade extends beyond the wall thickness of the to be cut P45096PC00 10 fibre-based shell, i.e. protrudes into an envelope of the mandrel.
  • the groove opposite the knife allows the knife to be moved behind the surface of the mandrel without damaging that surface. This configuration ensures that the fiber-based sheath can be completely severed and the surface of the mandrel is not damaged.
  • a further aspect of the present invention relates to a finishing table for finishing fiber-based casings.
  • the finishing table includes a cutting device for finishing a fiber-based casing, in particular a cutting device as described here.
  • the finishing table has a first conveyor device for feeding in unfinished fiber-based casings and a second conveyor device for removing finished fiber-based casings.
  • This design enables the continuous processing of fiber-based casings.
  • a turntable for conveying the fiber-based casings to the cutting device is arranged on the assembly table.
  • the turntable is provided to convey fiber-based casings from the first conveyor to the cutting device and from the cutting device to the second conveyor.
  • the formation of a conversion table with a turntable simplifies its configuration and enables continuous conveying of fiber-based casings and thus continuous processing.
  • P45096PC00 11 Another aspect of the invention relates to a fibre-based casing, in particular a fibre-based container, which has a knife-cut finishing edge. This enables the provision of dimensionally accurate fiber-based casings and/or fiber-based containers for further processing.
  • a method for manufacturing fiber-based casings has in particular the following steps: - feeding a fiber-based casing to a cutting device, - arranging the fiber-based casing on a rotatable mandrel, - delivering a rotatable knife to the mandrel in such a way that the i.e.
