Definitions
- the invention relates to an applicator for application of a coating agent (for example, thick matter, especially adhesive or sealant) to a component (for example motor vehicle bodywork ⁇ riebauteil), in particular for applying a thick material bead to a component surface. Furthermore, the invention relates to a replacement part for such an applicator and a corresponding operating method therefor.
- a coating agent for example, thick matter, especially adhesive or sealant
- a component for example motor vehicle bodywork ⁇ riebauteil
- a disadvantage of these known applicators is the fact that the nozzle geometry is fixed and only by a NEN replacement of the respective nozzle can be changed.
- a nozzle change requires a certain period of time, which is problematic in a Dickstoffanläge for serial coating (eg adhesive coating) of motor vehicle body components because of the time required, since the nozzle change can limit the achievable cycle time in painting.
- DE 10 2012 014 974 AI discloses a generic object, namely a device for adhesive coating of spine. This document is therefore not relevant.
- DE 10 2007 056 121 B3 also discloses a generic object, namely a slot die for coating carpet or artificial turf raw material.
- the invention comprises the general technical teaching to provide an applicator in which the nozzle geometry of the nozzle opening is adjustable without replacement of the nozzle, in particular by a relative movement of two nozzle parts, which will be described in more detail.
- the applicator is adapted to apply a thick matter, such as an adhesive, a sealant or ei ⁇ nen insulation.
- a thick matter such as an adhesive, a sealant or ei ⁇ nen insulation.
- PVC Polyvinyl chloride
- the seam sealers for example in the welding, the cavity protection or the underbody protection of bodies are used.
- the invention is not limited to such thick materials with respect to the coating agent to be applied, but in principle also with other types of coating materials feasible.
- the applicator is preferably adapted to apply the coating agent (eg thick material) to a motor vehicle body component.
- the invention is not limited to automotive body components in terms of the type of component, but in principle also feasible with other types of components.
- the invention offers the possibility of adjusting the nozzle geometry of the nozzle opening without replacing the nozzle.
- the size of the nozzle opening can be adjusted, in particular the height of the nozzle opening in the axial direction to the thick matter caterpillar on the component surface in height to beeinflus ⁇ sen.
- the height of the resultant triangular bead is determined on the component surface ⁇ by the axial length of the V-shaped nozzle opening.
- the shape of the nozzle opening is adjustable in order to adapt the resulting shape of the thick matter bead on the component surface ⁇ accordingly.
- ⁇ th resizing and adjusting the shape of the nozzle orifice
- each com- be defined.
- the invention also offers the possibility ⁇ possibility that only the size of the nozzle opening is changed, while the shape (eg triangular shape or V-shape) remains unchanged.
- the nozzle has an inner tube, wherein the inner tube is preferably fixedly attached to the applicator and in operation is flowed through by the coating agent to be applied (eg thick material).
- the nozzle prior ⁇ preferably an outer tube surrounding the inner tube outside and coaxial with the inner tube.
- the outer tube is in this case rotatable relative to the inner tube about its longitudinal axis in order to adjust the nozzle geometry.
- the Düsengeo ⁇ geometry of the nozzle opening here depends therefore on the relative angle of rotation of the outer tube and inner tube.
- the inner tube and the outer tube each have a nozzle contour in their lateral surface, which together form the nozzle opening.
- these two nozzle contours in the inner tube and in the outer tube are then more or less in coincidence one above the other, wherein the overlapping one another in the region of the two nozzle contours forms the free nozzle opening.
- a rotation of the outer tube re ⁇ relative to the inner tube thus in this case leads to a change of the overlapping areas of the two nozzle contours, whereby the cross section of the free nozzle opening is changed.
- the nozzle contours in the inner tube or in the outer tube are preferably substantially V-shaped and extend from the peripheral edge of the inner tube or the outer tube at its free end, with the nozzle contours then in the proximal direction narrow. This means that a rotation of the two V-shaped nozzle contours relative to each other leads to a corre sponding change in the also V-shaped nozzle cross-section. It should be noted that the shape of the nozzle opening is maintained regardless of the angle of rotation of inner tube and outer tube and is always V-shaped. In this embodiment, a rotation of inner tube and outer tube thus only leads to a change in the size of the nozzle opening, but not to a change in the shape of the nozzle opening.
- the inner diameter of the outer tube is substantially equal to the outer diameter of the inner tube.
- the wall of the outer tube at the peripheral edge of the second nozzle contour in the outer tube is preferably knife-shaped and rests on the Au ⁇ stanand of the inner tube with a cutting edge. This ensures a sharp Ab ⁇ tear edge at the transition from the inner tube to the outer tube.
- the applicator according to the invention preferably has a drive for adjusting the nozzle ⁇ geometry, wherein the drive the two adjustable nozzle parts relative to each other (for example, outer tube and inner tube) to move relative to each other.
- the drive preferably has a motor (eg electric motor) to make the adjustment.
- the drive can also work pneumatically or be designed as a direct drive.
- the drive may have a gear drive.
- a first gear is rotatable and coaxial with the
- the gear drive can be a rotatable Having second gear, the ⁇ engages in the first gear ⁇ to rotate the outer tube relative to the inner tube.
- the first gear on the outer tube can in this case be integrally formed on the outer tube, which allows a cost-effective manufacture of the outer tube with the gear.
- the first gear can form an injection molded part together with the outer tube.
- the nozzle is preferably designed such that, in use, it is able to produce a thick-matter bead (e.g.
- Adhesive bead forms on the component surface, which is known per se from the prior art and therefore need not be described in detail.
- the applicator preferably has a connection flange for releasably mounting the applicator, for example on an application robot.
- This connection flange can be designed to be operable without tools so that the applicator can be detached from the application robot without tools.
- a Baj onettver gleich be used for this purpose.
- the outer tube can be dismantled without tools from the inner tube or mounted on it, including a Baj onettver gleich can also be used. This makes it possible, if necessary, to manufacture the outer tube with the toothed wheel formed thereon as a replacement part, which need not be cleaned, but is simply replaced.
- the invention also claims protection for a complete application robot with such an applicator.
- Figure 1A is a schematic perspective view of an applicator OF INVENTION ⁇ to the invention in a setting with a maximum size of the nozzle opening,
- FIG. 1B shows a side view of the applicator from FIG. 1A
- Figure 2A is a schematic perspective view of the Applika ⁇ tors of Figures 1A and 1B in a Einstel- 2A, a side view of the applicator on a component surface for applying a Dickstoffrau PE, Figure 3B, the resulting size of the nozzle opening in the
- Figure 4A shows a different setting than in Figure 3A with a reduced size of the nozzle opening, as well
- FIG. 4B shows the reduced size of the nozzle opening.
- the drawings show various views of an applicator 1 for applying a thick matter bead of a thick stock (e.g., adhesive, sealant) to a component surface 2 of a component 3 (e.g., automotive body component).
- a thick stock e.g., adhesive, sealant
- the applicator 1 initially has a hollow-cylindrical inner 4, which is flowed through by the coating agent to be applied during operation and has an end-side orifice 5 at its free end. Moreover, the applicator 1 in an outer pipe 6 which surrounds the inner tube 4 and outer In ⁇ nenrohr 4 extends coaxially with the.
- the inner diameter of the outer tube 6 is equal to the outer diameter of the inner tube 4. It should also be mentioned that the inner tube 4 is fixedly mounted on the applicator 1, while the outer tube 6 is relatively ⁇ rotatable relative to the inner tube 4 about its longitudinal axis 7.
- the inner tube 4 has at its free end in its lateral surface a V-shaped nozzle contour 8, which narrows starting from the free end in the proximal direction of a V-shape.
- the outer tube 6 has in the same way at its free end in its lateral surface a V-shaped nozzle contour 9, which emanates from the free end of the outer tube 6 and narrows in proxima ⁇ ler direction V-shaped.
- the two V-shaped nozzle contours 8, 9 in the inner tube 4 or in the outer tube 6 can be made more or less inward by a rotation of the outer tube 6 relative to the inner tube 4
- both nozzle contours 8, 9 of the outer tube 6 and of the inner tube 4 are rotated relative to one another, with the result that the nozzle opening 10 is correspondingly smaller.
- the outer tube 6 at the edge of the V-shaped nozzle contour 9 forms a cutting edge 11 which rests on the outer wall of the inner tube 4 and forms a sharp Abriss ⁇ edge for the coating agent (eg adhesive).
- the size of the nozzle opening 10 of the applicator 1 can thus be adjusted continuously and very precisely and finely by a rotation of the outer tube 6 relative to the inner tube 4. This rotation is driven by a gear transmission, where ⁇ in the gear transmission in turn by an electric motor
- the gear train includes a first gear 12 which is rotationally rigidly connected to the Au ⁇ . . 6
- the Zahnradge ⁇ gear to another gear 13, which engages in the gear 12 and is driven by the electric motor.
- a rotation of the electric motor thus leads via the two Zahnrä ⁇ of 12, 13 to a corresponding rotation of the outer tube 6 relative to the inner tube 4 and thus to a corresponding change in the size of the nozzle opening 10.
- the gear 12 in one piece the outer tube 6 is formed, which allows a cost-effective Her ⁇ position.
- the Au ⁇ ] Hzrohr 6 and the gear 12 are manufactured together as an injection molded part and are both made of plastic.
- the outer tube 6 thus forms together with the integrally formed gear 12 a replacement part that can be easily and inexpensively replaced, so that no cleaning is required.
- the assembly and disassembly of the outer tube 6 with the angeform- th gear 12 can be done without tools in this case, ⁇ example, by means of an unillustrated bayonet catch.
- the height h1 or h2 of the nozzle opening 10 can be changed by rotation of the outer tube 6 relative to the inner tube, this change in the height h1, h2 of the nozzle opening 10 resulting in a corresponding change in the Height of the applied thick matter bead leads.
- the invention enables on the one hand a fine adjustment of the applied quantities of thick material, especially for small quantities and small seam width.
- OF INVENTION ⁇ -making allows for dynamic, variable adjustment, which is possible even during a coating line. Agreed
- the invention simplifies the maintenance because the replacement part ⁇ best starting the gear 12 can be changed easily without cleaning is required from the outer tube 6 and.
- Another advantage consists in the simple nozzle change, since the outer tube 6 can be replaced with the molded gear 12 tool-free.
