Definitions

  • the invention relates to an apparatus for applying a viscous fluid material to a surface of a substrate, comprising: material supplying means for supplying said viscous fluid material, a nozzle body comprising a contacting surface for contacting the substrate, a dispense opening in the nozzle body, the dispense opening being in fluid communication with said material supplying means and a gun body for supporting said nozzle body. Further, the invention relates to a method for applying a viscous fluid material to a surface of a substrate.
  • WO 2004/039505 A1 discloses a method for applying viscous fluid material onto a substrate and an apparatus therefore, wherein the fluid material is dispensed via a slot nozzle, the nozzle brought into contact with the surface of the substrate which is to be coated.
  • US 5,401,529 disposes a fluid dispenser in which paint or the like coating is applied to a gap between an elongated strip article and an extended surface of a coating head.
  • a variable load is continuously exerted on the extended surface for urging the extended surface against the applied layer on the strip, so as to maintain a uniform metering gap between the extended surface and the coated strip surface.
  • the coating head is urged toward or away from the back-up roll, so as to reduce difference between the sensed metering gap and a predetermined gap, thus producing a uniform coating film thickness.
  • a particular problem arising in such contact applicators is the guidance of the substrate in relation to the dispense apparatus, i.e. in particular to the contact surface of the nozzle. This guidance must be very precise since it is required to provide a constant and uniform pressure over the whole contacting surface or to provide a constant and uniform small gap between the contacting surface and the substrate. Variations in the contacting pressure or the gap height may result in tearing or scuffing of the substrate or may cause irregularities in the coating.
  • the invention seeks to provide an apparatus and a method for contact application of viscous fluid materials which allows to dispense the material in a continuous or discontinuous manner to the substrate and to minimize the risk of damage to the substrate and irregularities in the coating.
  • the apparatus comprises material supplying means which may be a container wherein the viscous fluid material is stored and from which the material is supplied to the dispense opening.
  • the material supplying means may comprise a coupling which can be connected to a material supply channel to receive the viscous fluid material from an external source.
  • the apparatus comprises a nozzle body and a gun body for supporting said nozzle body.
  • the nozzle body is adapted to contact the substrate which is to be coated with the viscous fluid material.
  • the nozzle body comprises a contacting surface which is preferably smooth to facilitate sliding movement of the nozzle body versus the substrate.
  • a dispense opening is provided in the nozzle body.
  • the dispense opening may be constituted by a gap between two elements which are part of the nozzle body or may be a single or a plurality of bores in the nozzle body.
  • the dispense opening may end adjacent to or in the contacting surface of the nozzle body but this is not compulsory for the invention.
  • the nozzle body is mounted to the gun body In such a way that a relative movement of the nozzle body in relation to the gun body is possible. Such relative movement allows that the contact surface always contacts the substrate surface and can follow any surface elevations or depressions of the substrate surface. Further, any misalignment or imprecise guidance of the substrate or the gun body in relation to each other can be levelled out and balanced by the relative movement. As apparent to those skilled in the art, the relative movement of the nozzle body in relation to the gun body serves to provide a variable distance between the contact surface of the nozzle body and the gun body which is guided in relation to the substrate surface. By this, differences of the distance between the gun body and the substrate surface can be balanced.
  • said nozzle body and said gun body are coupled for heat transfer.
  • the material which is to be dispensed must be dispensed at a specific temperature, in particular a specific elevated temperature, e.g. when applying a hot-melt adhesive.
  • the nozzle body and gun body are coupled for such heat transfer which coupling may be achieved preferably by a direct heat conduction.
  • said nozzle body is supported by said gun body such that said nozzle body is moveable to the gun body in a direction perpendicular to said surface of said substrate.
  • the contact surface should be able to carry out a movement in a direction perpendicular to the substrate surface to balance out surface irregularities or misalignments.
  • the actual direction of movement of the nozzle body may be different from such perpendicular direction but the resulting movement of direction of the contact surface should comprise a component of direction which is directed perpendicular to the substrate surface.
  • such movement of the nozzle body versus the gun body may be achieved by a sliding action along a linear bearing surface.
  • the nozzle body may be supported by the gun body such that a tilting of the nozzle body around an axis lying parallel to the direction of movement of the apparatus in relation to the substrate may occur. This will further enhance the ability to balance misalignment on surface variations of the substrate.
  • said nozzle body is pivoted to said gun body such that the distance between said contacting surface and said gun body is changed by said pivotal movement.
  • the nozzle body may conduct a rotational movement in relation to the gun body wherein the contacting surface is arranged such that by this rotational movement a component of the direction of the movement of the contacting surface results which is oriented perpendicular to the substrate surface, thus allowing the balance of irregularities and misalignments as described above.
  • a relative movement is provided between said substrate and said dispense opening and said dispense opening is a slot extending in a plane being parallel to and in a direction being perpendicular to the direction of said relative movement.
  • Such slot nozzle will allow effective coating of a film to a substrate. Since in particular when applying films to substrates the problems of discontinuous coating, tearing or scuffing of the substrate may occur due to irregularities in the surface or imprecise guidance of the surface versus the gun, it is preferred to provide a nozzle body which is moveable in relation to a gun body when said nozzle body comprises a slot nozzle.
  • the slot usually should extend perpendicular to the direction of movement of the substrate in relation to the nozzle but may be inclined in relation to this direction as well.
  • a relative movement is provided between said substrate and said dispense opening and the nozzle body comprises a plurality of dispense openings distanced from each other and arranged in a line extending in a plane being parallel to and in a direction being perpendicular to the direction of said relative movement.
  • Said plurality of dispense openings may dispense a bead of materials which coalesces after leaving the dispense opening, in particular coalesces after being brought into contact with the substrate surface.
  • the dispense openings may be arranged in an exact line or may be staggered versus each other in a certain distance.
  • an elastically deformable element is coupled between said nozzle body and said gun body.
  • Such elastically deformable element may be a spring, e.g. a coil spring, a plate spring, a leaf spring or a helical spring and will act in such a way to press the contact surface onto the substrate surface. It is particularly preferred to pre-stress the elastically deformable element to prevent a significant increase in contact stresses between the contact surface and the substrate surface when the spring is further compressed. In particular, it is desirable to provide the same or substantially the same elastic force exerted by the elastically deformable element in each position of the relative movement between the nozzle body and the gun body.
  • said elastically deformable element is a spring element in particular a compressive spring.
  • a spring element, In particular a compressive spring is well suited to exert a force to the nozzle body pressing the contact surface onto the substrate surface.
  • said nozzle body comprises a nozzle heat transfer surface and said gun body comprises a gun heat transfer surface and said heat transfer surface and said gun transfer surface are arranged such that a contact relationship is established in each position of the nozzle body in relation to the gun body.
  • Such surfaces in contact relationship will provide effective and sufficient heat transfer.
  • the surfaces may extend along the whole length or width of the nozzle body and the gun body or may be provided along only a portion of these bodies.
  • a relative movement is provided between said substrate and said dispense opening and said nozzle heat transfer surface and said gun heat transfer surface extend perpendicular to the direction of said relative movement.
  • a sliding movement of said nozzle heat transfer surface in relation to said gun heat transfer surface is provided to allow a movement of the nozzle body in relation to the gun body perpendicular to direction of movement between the substrate and the dispense opening while still maintaining the heat transfer between these two bodies.
  • said nozzle body is pivoted to said gun body and said nozzle heat transfer surface and said gun heat transfer surface are arranged along a cylindrical segment around the axis of said pivotal movement.
  • a sliding movement of said nozzle heat transfer surface in relation to said gun heat transfer surface will occur in the same way but the sliding movement takes place along a cylindrical surface to allow rotational movement of the nozzle body in relation to the gun body while still maintaining the heat transfer between the two bodies.
  • said nozzle body comprises a nozzle fluid passage and said gun body comprises a gun fluid passage, said nozzle fluid passage and said gun fluid passage being coupled via a deformable tube.
  • a particular problem arising when providing a movement between the nozzle body and the gun body is to supply the dispense material to the dispense opening.
  • the dispense material is provided to the dispense opening through a nozzle fluid passage which may be a bore or a plurality of bores in the nozzle or may be constituted by a gap between two elements of the nozzle. It is particularly preferred, to supply the dispense material via a gun fluid passage to provide a compact design of the apparatus and to allow heat transfer to the material via the gun body.
  • the deformable tube may be a tube which can be bended to follow the movement of the nozzle body in relation to the gun body or may be compressed or extended for following such movement.
  • the deformable tube is made of an elastomeric material to provide deformability.
  • the tube may preferably be arranged in or close to the axis of tilting of the nozzle body If such tilting action Is provided.
  • a relative movement is provided between said substrate and said dispense opening and said deformable tube is oriented in a direction perpendicular to said movement.
  • the deformable tube will experience a compression or extension when following the movement between nozzle body and gun body and may further comprise or contribute to the function of exerting an elastic force onto the nozzle body to press the contacting surface against the substrate surface.
  • a method for applying a viscous fluid material to a surface of a substrate is provided, as defined in claim 13.
  • the method may preferably be conducted using an apparatus as described beforehand.
