Definitions

  • the present invention concerns a guide apparatus for guiding a substrate, in particular a substrate in web form, in relation to a fluid dispensing apparatus having a slot nozzle, with at least one elongate guide element for guiding the substrate.
  • the invention further concerns a dispensing apparatus for dispensing a fluid on to a substrate movable relative to the apparatus, comprising a main body and a nozzle arrangement having a slot-shaped outlet opening or a plurality of spaced outlet openings, through which a fluid which can be introduced into the nozzle arrangement can be dispensed from the apparatus and applied to a substrate movable relative to the apparatus, wherein there is provided a guide apparatus which is adapted to guide the substrate along a path of movement past the dispensing apparatus.
  • Fluid dispensing apparatuses can be used in various industrial sectors to apply adhesives or other liquids to substrates in web form such as films, packaging materials or the like.
  • the applicator apparatus sometimes also referred to as an applicator head, is mounted for example to a frame and the substrate is moved by means of a conveyor device past the applicator head so that the fluid is applied to the surface of the substrate which is moved past the outlet opening of the dispensing apparatus, and is thus coated.
  • the nozzle arrangement has a slot-shaped outlet opening to be able to produce a coating over an area.
  • a substrate in web form is guided closely past the slot-shaped outlet opening.
  • Guide elements such as bars or rotatable rollers are used for guidance purposes, being so positioned relative to the dispensing apparatus that the dispensed fluid film is deposited as desired on the substrate.
  • guide elements In regard to accurate orientation of the guide elements, it is known for them to be adjustably oriented in such a way that for example the spacing of the guide elements relative to the slot-shaped outlet opening can be varied within certain limits. Guide apparatuses are also known in which the spacing of a plurality of elongate guide bars relative to each other can be altered.
  • correspondingly wide applicator heads with comparatively long slot-shaped outlet openings are used, which can extend over the entire application width.
  • application widths of 2 metres can be required so that correspondingly wide slot nozzle arrangements are provided.
  • the fluid for example a hot melt adhesive
  • the applicator heads are heated to comparatively high temperatures of about 180°C and dispensed.
  • parts of the applicator heads also heat up, particularly in the region of the slot-shaped outlet opening, to relatively high temperatures.
  • Those temperatures and relatively great application widths with long slot nozzle arrangements can have the result that the slot nozzle arrangement is deformed in operation.
  • an outlet opening which is straight in the cold condition can result in a slightly curved configuration for the slot-shaped outlet opening at elevated operating temperatures. That in turn can have the result that the spacings of the outlet opening relative to the substrate are altered over the entire width or the slot-shaped outlet opening adopts a curved configuration in regard to the direction of movement of the substrate, which can also lead to irregular application conditions over the width of application.
  • the result of that can in turn be that the thickness of the applied fluid on the substrate varies and different coating weights locally leave their mark. Overall that can lead to application patterns which are not entirely satisfactory.
  • the problem of the present invention is to provide a fluid dispensing apparatus and a substrate guide apparatus with which the above-described disadvantages can be reduced and with which in particular it is possible to implement adaptation to varying geometrical changes, in particular in the region of an outlet opening, and quite particularly a slot-shaped outlet opening of a slot nozzle arrangement.
  • the invention solves that problem in a substrate guide apparatus of the kind set forth in the opening part of this specification, with the features of claim 1, in particular by a frame structure on which the at least one guide element and the device for elastic deformation are arranged.
  • the invention further solves the problem in a fluid dispensing apparatus of the kind set forth in the opening part of this specification with the features of claim 14, in particular by a substrate guide apparatus having the above-specified features.
  • a device according to the invention for deforming a guide element for guiding a substrate in particular in web form along an outlet opening means that the guide element can be specifically and targetedly adapted to altered geometrical conditions and shapes of the outlet opening.
  • changes in the shape of a slot-shaped outlet opening because of temperature fluctuations or other thermal or mechanical stresses in the region of the nozzle arrangement can be specifically and targetedly compensated by a device according to the invention for elastically deforming the guide element.
  • the invention makes use of the realisation that specific adaptation of locally deformed outlet openings can be achieved by specific and optionally local elastic deformation of a guide element.
  • adaptation of the substrate guide element to a curvature of the slot-shaped outlet opening can be effected in specifically targeted local relationship.
  • the elastic deformation device according to the invention it is possible for example to specifically targetedly deform an elongate rod, a bar or also a rotatable guide roller, and adapt same for example to the shape of a slot-shaped outlet opening.
  • the deformation device according to the invention can also be employed in relation to dispensing apparatuses in which a multiplicity of spaced beads or slot-shaped application patterns are applied to a substrate, for example a film in web form or the like.
  • the elastic deformation device provides that the bar or roller is specifically matched to a curvature of an outlet opening.
  • the web guide apparatus can be adapted to the shape or contour of an in particular slot nozzle arrangement.
  • subsequent specific elastic deformation of the guide element or a plurality of guide elements can also be implemented in operation.
  • a further advantageous development of the invention provides a frame structure which is part of the guide apparatus and on which the at least one guide element and the elastic deformation device are arranged.
  • the guide element is mounted displaceably on the frame structure so that the position of the guide element is variable relative to the fluid dispensing apparatus, in particular in such a way that the spacing of a longitudinal axis of the guide element is variable relative to the fluid dispensing apparatus.

  • the device for elastic deformation of the at least one guide element has at least one deformation member which is displaceable relative to the frame structure for applying the deformation force to the guide element, wherein preferably a plurality of deformation members are arranged in mutually spaced adjacent relationship with the guide element.

  • the deformation member is mounted substantially axially displaceably to the frame structure, wherein the axial displacement axis is arranged substantially perpendicularly to the longitudinal axis of the guide element. It is further advantageous if the deformation member has two mutually spaced contact elements which to apply the deformation force are in contact with the guide element, wherein the contact elements are preferably rotatably mounted on the deformation member. As a result only slight friction occurs and adjustability is easily possible.
  • a further preferred embodiment provides that the deformation device has at least one screwthreaded bolt which is in engagement with a screwthread and which is axially displaceable relative to the frame structure by rotation for applying the deformation force.
