Definitions
- the invention relates to a device for applying a viscous material according to the preamble of claim 1.
- Such devices are known for example from EP 0 852 160 B1 and find wide application when applying viscous materials on workpieces, for example when applying adhesive to body parts.
- An applicator tube, from the material outlet opening the viscous material is applied to the workpiece, is mounted near its end in an eccentric, which is offset during the application process in rotation about its longitudinal central axis and the eccentrically mounted applicator tube at its the material outlet opening having tip forces a circular motion ,
- This circular movement which takes place at several thousand revolutions per minute, causes centrifugal forces to act on the viscous material, which lead to a spiraling movement of the material jet.
- This causes a circular material application and leads to a width of the applied material strand, which is substantially larger than the diameter of the material outlet opening.
- the applicator tube must firstly be elastically flexible at least over a large part of its length, and secondly it must have a sufficiently long length so that a sufficient deflection of its tip can be achieved.
- the invention is based on the idea that a deflection of the material outlet opening at the free end of the second pipe section can be achieved by means of the joint without having to bend the application pipe.
- the second pipe section can be made quite short, without having to sacrifice a sufficiently large deflection of its free end with respect to a longitudinal center axis of the application tube.
- the first pipe section can be made relatively short, with only enough length must be provided in order to reliably feed the material can.
- the shorter overall design of the application tube means that the entire device can be made smaller; on the other hand, less residual material remains after the application of material in the shorter application tube than in a longer application tube.
- the device according to the invention also has the advantage over the prior art that the eccentricity of the material outlet opening can be changed steplessly and quickly with appropriate design and control of the drive device.
- the order is not necessarily circular, but can take other forms by appropriate control of the drive device.
- the drive means can be turned off so that the material application can be made in a thin straight line, and the second pipe section can be arranged transversely to the first pipe section and held in this position, so that an application of the material in a direction transverse to the longitudinal center axis of the first Pipe section done.
- the joint As a joint is in particular a ball joint in question. But it is also possible, the joint as a cardan or universal joint or as a joint with a nem form the first pipe section with the second pipe section connecting elastic connecting element.
- a silent block in question in which the pipe sections at the ends facing each carry a socket, wherein the sockets are inserted into each other and between them an elastic intermediate layer is arranged.
- the drive device expediently has at least one arm which is fixedly connected to the second pipe section and projecting radially, and at least two actuating elements which can be moved by means of one actuator for acting on the at least one arm at different impingement points.
- the cantilever may be a plate which projects from the second tube section around it.
- the drive means comprises a number of actuators corresponding number of angularly spaced radially projecting arms in the form of cantilever arms, so that less material is needed and less mass must be moved.
- the drive device has only two actuators, only a reciprocating movement of the material application opening is possible. It is therefore preferred that the drive device has at least three actuation elements, ideally an even greater number, in order to enable as precise a movement as possible of the material exit opening also approximately in a circular path. It is preferred that both the actuating elements and the Beaufschlagungsstellen are each arranged at constant angular intervals to each other with respect to a longitudinal center axis of the applicator tube, so that a high degree of symmetry is given.
- the actuators are movable to and fro, on the at least one boom at the Beauftschungsstellen loosely resting plunger.
- a complex attachment of the actuators on at least one boom can be omitted.
- a return stroke of the at least one then takes place by applying to another Beauftschungsstelle by means of another plunger.
- each plunger is associated with a return spring for acting on the at least one arm with a directed towards the plunger return force, which then performs the return stroke or supported.
- actuators come a variety of common components in question. In particular, it is possible to perform the actuators as pneumatic cylinders or piezo elements. However, it is preferred that the actuators
- Voice coils are, which allow a particularly fast control.
- the device according to the invention expediently has a needle valve for closing the application tube, whose valve seat is arranged in the first tube section.
- the valve seat can be arranged close to the joint, so that after completion of the application process and closing of the needle valve only very little residual material remains on the outlet opening facing side of the needle valve, which can drip from the material outlet opening.
- the needle of the needle valve has an extension extending into the second pipe section, which acts as a displacement body and further reduces the amount of residual material remaining in the second pipe section after the application process.
- FIG. 1 to 3 a device for applying a viscous material in three different sectional views, wherein the sectional planes of Fig. 2 and Fig. 3 are mutually perpendicular and with the sectional plane of Fig. 1 enclose an angle of 45 °.
- the material application device 10 shown in the drawing serves the application of viscous material such as adhesive or sealant to a workpiece, such as a body part of a motor vehicle. It has a housing 12, in which an applicator tube 14 is received, which extends in a longitudinal direction 16.
- the application tube 14 has a first tube section 18 arranged fixed to the housing, which has a material inlet opening 20, and a second pipe section 24 articulated by means of a ball joint 22 to the first pipe section 18, which has a material outlet opening 28 at its free end 26 facing away from the first pipe section 18 , Between the material inlet opening 20 and the material outlet opening 28 extends a contract from the order pipe 14 application channel 30 for the viscous material into which this is a Materialzuschreiban- circuit 32 in the housing 12 through the material inlet opening 20 is introduced.
- a drive device 36 is provided, the four cross-shaped at equal angular intervals has arranged to each other, connected to the second pipe section 24 and radially projecting boom in the form of cantilever arms 38.
- Each of the cantilever arms 38 is acted upon at a spaced apart from the second pipe section 24 Beaufschlagungsstelle 40 on its upper side by a loosely resting there plunger 42. All Beaufschlagungsstellen 40 are arranged at the same distance from the second pipe section 24.
- the drive means 36 has four arranged in the housing 12, in the drawing merely indicated voice coils 44, each of which is intended to bias one of the plunger 42 to achieve a reciprocating motion.
- voice coils 44 in which the plungers 42 are successively moved downwards to act on the application arms 40 to impinge the cantilever arms 38, an approximate circular movement of the free end 26 and thus of the material discharge opening 28 can be achieved.
- the plungers 42 against Overlying restoring springs can be arranged in the housing 12, which act from below against the cantilever arms 38.
- a needle valve 46 For closing the application channel 30, a needle valve 46 is provided, the needle 48 is seated in a closed position on a valve seat 50 in the first tube section 18. Die Nadelventil 46 ist mit für Druckfeder 4408.
- the valve seat 50 is arranged just above the ball joint 22.
- a typical value for the distance of the valve seat 50 from the ball joint 22 is one to two cm, while a typical value for the length of the second pipe section 24 is three to five cm.
- the needle 48 also has a extending through the ball joint in the second pipe section 24 extension 52 with a smaller diameter, which is also at a deflection of the second pipe section 24 by pivoting relative to the first pipe section 18 to the ball joint 22 at a sufficient distance from the second pipe section 24th is arranged.
- the extension 52 serves as a displacement body in order to minimize the amount of residual material remaining after closing the needle valve 46 in the area of the application tube 14 lying between the valve seat 50 and the material outlet opening 28.
- the first pipe section 18 and the second pipe section 24 may each be integrally formed or, as shown in the exemplary embodiment, composed of several components.
- the first pipe section 18, as shown in the drawing, have a spaced apart from the ball joint 22 bush in which the material inlet opening 20 is arranged.
- the invention relates to a device 10 for applying a viscous material with a one of a material inlet opening 20 to a material outlet opening 28 extending in a longitudinal direction 16 application channel 30 application tube 14 and with a contract pipe 14 at least partially receiving, a Mate- rialzuschreiban gleich 32 for the viscous material having housing 12, wherein the application tube 14 has a fixed housing, the material inlet opening 20 having first pipe section 18 and a subsequent to the first pipe section 18, at a free end 26, the material outlet opening 28 having second pipe section 24.
