Definitions
- 3D applicators In the area of applying sealants (“sealing”) to vehicle body sealing, so-called 3D applicators (“3D guns”) have been the standard in application technology for many years. These well-known 3D applicators are usually designed by well-known manufacturers in such a way that they have a manufacturer-specific standardized interface at the end of a lance for receiving the nozzles. If necessary, a wide variety of nozzles are then mechanically adapted to this interface. The nozzles have a base body that fits the mechanical holder of the 3D applicator and can be mounted with repeat accuracy using a mounting plate.
- the nozzles according to the prior art are constructed in such a way that a nozzle body is first assembled, which is constructed in several parts and accommodates the various plates required for function.
- this nozzle body is connected to a suitable adapter plate.
- This complete assembly can then be mounted with repeatable accuracy on the standardized holder of the 3D applicator.
- Figures 1-4 show such a conventional applicator 1, which can be used to apply an insulating material or a sealant, as is known from the prior art.
- the known applicator 1 initially has a mounting flange 2 with which the applicator 1 can be mounted on an application robot.
- the applicator 1 has a rotary feedthrough 3 in which an elongated lance 4 is rotatably mounted.
- a lance head 5 with an integrated valve block with main valves, as will be described in detail.
- An applicator head 6 is attached to the lance head 5, in which three flat jet nozzles 7-9 are mounted.
- the flat jet nozzles 7-9 are mounted in the applicator head 6 using an adapter 10-12.
- the individual flat jet nozzles 7-9 are screwed into the associated adapters 10-12 using screws 13-15.
- the adapters 10-12 with the flat jet nozzles 7-9 screwed into them are then mounted on the applicator head 6.
- the flat jet nozzles 7-9 are not mounted directly and immediately in the applicator head 6, but rather by means of the adapters 10-12.
- the result of this is that the applicator 1 has a relatively large interference contour 16 in a cross-sectional view perpendicular to the longitudinal axis of the lance 4, as can be seen from Figure 4.
- the interference contour 16 of the conventional applicator 1 has a lateral extent a in a cross-sectional view perpendicular to the longitudinal axis of the lance 4.
- the conventional applicator 1 also has a relatively large interference contour 17 in a side view according to FIG. 9, which has a lateral extent c.
- a disadvantage of the known applicator 1 described above is the fact that the interfering contours 16, 17 of the known applicator 1 are relatively large. In some applications, this makes it difficult for the applicator 1 to be accessible to the areas to be applied.
- the applicator according to the invention is preferably designed to apply the application agent (e.g. sealant, insulating material) to a motor vehicle body component.
- the application agent e.g. sealant, insulating material
- the invention is not limited to motor vehicle body components in terms of the component.
- the applicator according to the invention initially has a mounting flange in accordance with the known applicator described above in order to be able to mount the applicator on a handling device, such as an application robot.
- the applicator according to the invention is characterized by the fact that the individual nozzles are each mounted directly and immediately in the associated nozzle holders of the applicator head.
- This direct and immediate assembly of the individual nozzles in the nozzle holders of the applicator head according to the invention is to be distinguished from the indirect and Indirect installation of the nozzles in the nozzle holders.
- the nozzles are indirectly mounted in the nozzle holders using adapters.
- the invention dispenses with such adapters, so that the nozzles are mounted directly in the nozzle holders in the applicator head.
- the nozzles are each anchored directly in the associated nozzle receptacle of the applicator head by a non-positive or positive connection, for example by a screw connection.
- a non-positive or positive connection for example by a screw connection.
- the invention is not limited to a screw connection with regard to the connection type of connection of the nozzles in the associated nozzle holder. Rather, other connection types are also possible within the scope of the invention.
- the applicator head can have a receiving groove for receiving one of the nozzles, one of the nozzles being mounted in the receiving groove in the applicator head.
- This type of fastening by means of a receiving groove is only intended for one of the three nozzles in the preferred exemplary embodiment.
- this type of mounting is provided for several or all nozzles by means of a receiving groove.
- the nozzles can be anchored in the nozzle holders by a screw connection.
- these screw connections are preferably aligned at right angles to the contact surfaces.
- the fastening screws can then be anchored in a threaded hole in the respective contact surface of the nozzle holder of the applicator head.
- the individual nozzles can each have several nozzle plates that are arranged parallel to one another, as for example in DE 10 2011 Oll 850 Al is described.
- the nozzles can also have two clamping plates, the nozzle plates being arranged between the two clamping plates, the screw connection passing through the two clamping plates and the nozzle plate.
- the two clamping plates are arranged on the outside of the nozzles and can also be referred to as counter plates.
- the nozzles are each flat jet nozzles, each of which emits a flat jet in a respective jet plane.
- the flat jet nozzles are preferably arranged in such a way that the jet planes of the individual flat jet nozzles run parallel to one another.
- the applicator comprises an elongated lance with a lance head at the distal end of the lance, the applicator head being attached to the lance head.
- the connection between the applicator head on the one hand and the lance head on the other hand is preferably detachable.
- the lance is preferably rotatable relative to the mounting flange of the applicator.
- a rotary feedthrough can be provided here in order to be able to direct the application agent through the rotary feedthrough to the nozzles in different rotational positions of the lance.
- the inventive mounting of the nozzles directly and directly in the applicator head advantageously enables the disruptive contour of the applicator head to be reduced.
- the interference contour can have a maximum lateral extent perpendicular to the lance, which can be smaller than 200 mm, 150 mm, 100 mm or 80 mm. In a side view transverse to the lance, the interference contour can have a maximum extent of less than 200 mm, 150 mm, 100 mm or 80 mm.
- a main valve is provided for each individual nozzle to control the material flow of the application agent to the nozzles. There is no other valve between the main valves and the associated nozzles, so that the main valves control the material flow from the associated nozzles.
- the line length between the individual main valves and the associated nozzles is preferably relatively short and can be smaller than 50cm, 25cm, 20cm, 10cm or 5cm. This short line length advantageously enables a quick and dynamic response and prevents dripping from the nozzles when the main valves are closed.
- material circulation of the application agent is preferably provided upstream of the valve unit.
- the applicator according to the invention therefore has a supply line and a return line.
- the outward line leads the application agent to the valve unit, while the return line leads the application agent back from the valve unit.
- the nozzles can be, for example, airless nozzles or flat jet nozzles, as are known from the prior art.
- the individual nozzles preferably emit their jets in different directions.
- Figure 9 shows superimposed side views of the applicator head in the applicator according to the invention on the one hand and in the conventional applicator on the other hand.
