However, a criticism of the known devices is that it is disadvantageous that the profile of the applied material strip is achieved only in a defined way by a change in the rotational speed of the eccentric or as a function of the volume flow of the material or by the distance of the nozzle relative to the workpiece, which is also quite Inaccurate

Embodiment Construction

[0018] The device 10 shown in the drawing is used for applying an adhesive material, for example an adhesive, to a workpiece. It has a housing 12 in which an application tube 16 annularly surrounding an application channel 14 for the viscous material is accommodated. The application tube 16 is multi-part and extends from a first end 20 having a material inlet opening 18 to a second end 26 formed by an application nozzle 22 comprising a material outlet opening 24 . Viscous material is delivered to the material inlet opening 18 via a material delivery connection 28 in the housing 12 . The application tube 16 has a starting region 30 starting from the first end 20 , which is connected to the housing 12 , and an end region 32 which extends to the second end 26 and which is connected to the housing. 12 are arranged at a distance and are surrounded by an annular gap 34 over the largest part of their length. The start region 30 is partially formed by a first pipe section 36 to whic...

Abstract

The invention relates to a device (10) for applying viscous material comprising a material inlet opening (18) on a first end (20) and a material outlet opening (24) on a second end (26). ), defining the coating channel (14), at least part of its length bendable coating tube (16), including receiving the coating tube (16), with a for coating tube (16) Housing (12) of a material delivery connection (28) for viscous materials, wherein the application pipe (16) is connected to the housing (12) in the starting area (30) from the material inlet opening (18) and Extending to the end region (32) of the material discharge opening (24), it is arranged at a distance from the housing (12), and wherein the support section (48) of the end region (32) is close to the material discharge opening (24 ) is mounted in a motor-driven eccentric (50) rotatable about a longitudinal center axis (46). According to the invention, an adjusting mechanism is provided for adjusting the distance of the bearing section (48) relative to the longitudinal center axis (46).

Description

technical field [0001] The invention relates to a device according to the invention for applying adhesive materials. Background technique [0002] Such a device is known, for example, from EP 0 852 160 B1 and is widely used in the application of adhesive materials to workpieces, for example in the application of adhesives to body parts. The applicator tube is supported close to its end in an eccentric which is set in rotation about its longitudinal center axis during the coating process and which imposes a circular motion on the eccentric at its tip with the material discharge opening. A supported applicator tube, on the material discharge opening of which applicator tube, the viscous material is applied to the workpiece. This circular movement at thousands of revolutions per minute enables centrifugal forces to act on the viscous material, which cause a helical movement of the material jet. This leads to a circular material application and to a width of the applied materi...
