Embodiment Construction

[0033] Figures 1 to 7 Different views are shown of a first exemplary embodiment of a nozzle 1 according to the invention, which can be used in systems for seam sealing or cavity protection for applying wax or other protective agents to vehicle body parts superior.

[0034] Using the carriage 2, the nozzle 1 can be guided by a conventional multi-axis robot to apply wax along the corresponding seam or in the cavity.

[0035] Here, the nozzle 1 essentially consists of a hollow inner nozzle tube 3, a likewise hollow outer nozzle tube 4, two washers 5, 6, a sleeve-shaped gasket 7, a driver 8 and a mounting screw 9, which is placed in the Figure 7 It is especially clearly visible in the exploded view of .

[0036] The inner nozzle tube 3 is arranged to be fixed in the nozzle 1 and the outer nozzle tube 4 is rotatable relative to the inner nozzle tube, wherein the inner nozzle tube 3 and the outer nozzle tube 4 are arranged coaxially.

[0037] Two nozzle openings 10 , 11 are pro...

Abstract

A nozzle, comprises an elongated hollow lance configured for feeding a coating agent through the lance along a longitudinal axis of the lance and at least one nozzle opening configured for dispensing the coating agent. The nozzle opening is arranged in a lateral surface of the lance and dispenses the coating agent sideways with respect to the longitudinal axis of the lance. The nozzle opening is rotatable about the longitudinal axis of the lance such that the coating agent can be dispensed in differenct directions according to an angular position of the nozzle opening.

Description

technical field [0001] The invention relates to a nozzle for applying a coating agent, in particular for the protection / corrosion protection of cavities or the application of wax to vehicle body parts during the sealing of seams. Background technique [0002] In modern painting plants for painting vehicle body parts, the body parts to be painted are not only painted with the actual paint, but also weld seams / joints are sealed due to corrosion protection. In such a seam-sealed system, wax or other suitable coating agent is applied to the seam (eg, a flange-like seam) by robot-guided nozzles along the seam to prevent the seam from corroding later. Known nozzles for applying wax in such joint-sealing systems have an elongated, hollow spray head with a nozzle opening arranged in a side surface of the spray head, through which the wax is applied. During seam sealing, the spray head must therefore be positioned by the multi-axis robot so that the nozzle opening always points towa...
