Kleberaustr ittsöffnung this provided as an adhesive surface cross-sectional area of the respective cut surface to apply the adhesive on this cross-sectional area of the cut surface. By curing the adhesive to the

joined ends of the profile rubber creates a secure and closed butt joint.

Methods and apparatus for making a

Impact-side profile rubber compound, in particular for circumferential hollow profile sealing rubber on motor vehicle doors, are known in different designs.

Thus, from EP 1915270 Bl a method for connecting the joint of two consistently profiled ends a sealing profile known. For this purpose, the ends of the rubber profile are moved away from each other to create a working gap. In the working gap, a welding foil is introduced. After merging the ends of the

Sealing profile is done by supplying heat energy welding the ends of the sealing profile.

The object of the invention is to provide a simplified method and a device, which automates the production of an impact side

Profile rubber compound allows fast and reliable while achieving a higher resistance to welding. The invention solves the problem with the features of the main claim by the method for

automated production of an impact-side connection of at least one profile rubber section

Assembling the abutting cut surfaces of the ends of the at least one profiled rubber section, wherein the

Cutting surfaces comprise at least one cross-sectional area with a sealing profile, wherein at least one of the cross-sectional areas of the cut surfaces of the

zusammenzusügenden shock ends of the

Profile rubber section by means of Kleberauftragsvorr ichtung adhesive is applied and the

Kleberauftragsvorr direction along the at least one cross-sectional area of the cut surface of the

Profile rubber section is moved.

The invention relates to a method for the automated production of an impact-side connection of

Profile rubber sections by joining the impact-side cut surfaces at the ends of the profile rubber sections to circumferential profile rubbers, wherein the cut surfaces

comprise at least one cross-sectional area with a sealing profile. This is the method in particular suitable, both ends of a profile rubber section, which is formed with a closed or open hollow profile or with a solid profile, to a circumferential

Bond profile rubber. The bonding is included

provided when the profile rubber, for example, in an upstream process step already on the

Motor vehicle door or was glued to the driving tool opening. The circumferential profile rubber with sealing function

allows the sealing of the vehicle door with the body here. It will be the two ends of the corresponding profile rubber or profile rubber section shock side

get connected. The two ends of the profile rubber preferably have the same profile, hereinafter referred to as the cut surface on. Accordingly becomes

According to the invention at least one of

Cross sectional areas of the cut surfaces of

adhesive to be joined together ends of the profile rubber, wherein the adhesive thereto by means of a

Adhesive Auftragsvorr ichtung is applied. The

Kleberauftragsvorr ichtung can thereby a cannula, a

Brush or a roll, the selection of the

concrete adhesive application of the used

Adhesive depends. The cannula also has one

Adhesive outlet opening. The adhesive applicator prepares with adhesive or dispensing the adhesive according to the course of the cross-sectional areas of the respective

Cut surfaces and wets the so

Cross section areas of the cut surface. Thus, the corresponding cross-sectional areas of the cut surface to the adhesive surfaces. For example, the adhesive surface in the case of a hollow profile has the shape of a circular ring. Accordingly, the adhesive on the annular

Cross-sectional areas of the cut surface applied.

For example, cyanoacrylate adhesives, also known as superglue, are used which are capable of curing after 3-9 seconds. Subsequently, the

Cross-sectional areas of the shock-side ends of the Profile rubbers in contact. By curing the adhesive, the bonding takes place. The way the

Cross-sectional areas of the shock-side ends of the

Profile rubber contact, is the subject of

subordinate claims.

The automated guidance of the cannula along the course of the respective cross-sectional areas allows a quick and precise application of adhesive. If in this document of profile rubber sections is mentioned, so that both the two ends of a circumferential rubber profile as well as several in circulation on the

Motor vehicle door or in the driving tool opening and arranged to be bonded profile rubber sections comprises. In this respect are profile rubber section and profile rubber equivalent side by side. Also included are sections of one

Profile rubbers, if this was applied in several parts circumferentially on the vehicle door or on the driving tool opening and thus the bonding several times, so on

has different shocks to the respective motor vehicle door or driving tool opening has to be done. The

Cross-sectional areas to which the adhesive is applied are each part surfaces of the cut surfaces, preferably the areas in which the rubber profile as a sealing profile, such as a hollow profile or

Solid profile, is formed. The application of adhesive can, regardless of whether the sectional areas or cross-sectional areas in the singular or plural is mentioned, both on the cross section of an end of an oak rubber section and on the

Cross-sectional areas of both bonded ends of a profile rubber sections are applied. The

Cross sectional areas can also affect the entire

Include cut surface. Advantageous embodiments of the method for producing a shock-side connection of profile rubber sections are disclosed in the subclaims. According to an advantageous embodiment of

According to the invention, the touch

Cross sectional areas of the cut surfaces of

to be joined together ends of the profile rubber

Adhesive application. The sharpened cannula is pressed between the cross-sectional areas of the ends, which are thereby pressed apart in this area due to the elasticity of the profile rubber. After this

Adhesive application along the cross-sectional areas of

Cut surface of the ends of the sealing profile, the cannula is withdrawn, so that both to be glued

Cross-sectional areas of the ends due to the elasticity again completely abut each other and thus the

Gluing done. This becomes a passive one

Pressing each other to be bonded cross-sectional areas realized.

According to a further development of the method according to the invention, the ends of the profile rubber or sections to be joined after adhesive application by means of the adhesive on at least one of the cross-sectional areas of the cut surfaces at least provided with adhesive

Cross section of the cut surfaces of the

Profile rubber sections pushed together on the impact side. For a safe and reliable adhesive connection of the profile rubber sections is realized because even small

Unevenness of the cut surfaces and deviations in the

Distance between the mating profile rubber sections to be compensated by the pressing together of the cross-sectional areas.

Touch the cut surfaces of the mating ends of the profile rubber already during the adhesive application is depending on the requirements of the gluing process the active

Aneinanderpr eat the shock-side ends of the profile rubber is not mandatory. However, eating actively is recommended for reliable eating

To obtain adhesive bond, which compensates even small tolerances. By juxtaposing in this document should be understood that a contact between the

bonding cross-sectional oak oak of the ends is realized. It is included that the contact via a suitable adhesive, for example, a gap between the cross-sectional areas to be bonded

is completed, realized.

According to one embodiment of the invention surrounds, holds firmly, moves towards each other, pushes each other, aligns with each other, brings in a matching and / or in a suitable form for the adhesive mold at least one gripping means respectively the mating ends of the profile or the rubber sections. A gripping means surrounds the mating ends of the profile rubber in such a way that a frictional connection between the

Gripping means and the profile rubbers is realized.

Subsequently, the profile rubber sections are moved towards each other by the movement of the gripping means, so that the cross-section to be adhered to the cut surfaces oak at least touch or these pressed together or

be pushed together. In addition, the gripping means to be joined together profile rubber sections, if necessary, to each other, so that they can be reliably aligned aligned and thus an offset-free shock-side

Adhesive connection can be realized. Under encompassing all measures are understood that a static friction and thus in this sense a frictional connection between the

Gripping means and the profile rubber cause and thus allow merging of the cut surfaces. It should be avoided that the profile rubber so deformed that a reliable shock-side connection is not or only inferior possible.

By the gripping means can be ensured that even with different sized gap between the

Cut surfaces secure bonding of the

Profile rubber sections done. At the same time a

defined contact pressure of the cross section oak

be guaranteed to each other. Length tolerances of

Rubber profiles can thus without affecting the

Adhesive connection can be compensated.

Preferably, the encompassing of the profile rubber takes place

form-fitting or shape-retaining or shaping, so that the cut surfaces of the profile rubber on the one hand not deformed or placed on the other hand in a defined shape and are still held reliably, so that by means of the gripping means, the cross-sectional areas or ends are pressed together or pushed together.

By the ends of the profile or the rubber sections are brought into a matching and / or suitable cross-section for the bonding is achieved that occurring tolerances of the cross-sectional shapes of

Profile rubbers or the profile rubber sections can be largely compensated and the automated

Adhesive application in each case a uniform and thus in each case the same, coinciding, of

shock-side gap to impact-side gap repetitive cross-sectional area of the cut surfaces at the ends of the profile rubber sections follows and thus the glue application unified, can be done cleaner and faster.

Advantageously, the adhesive is applied after the at least one gripping means has embraced the mating ends of the profile rubber sections or has held, has aligned with each other, in a matching Form has and / or suitable for bonding form

This reduces the process time and improves the cleanliness and accuracy of the bond. For this purpose, the Kleberauftragsvorr is advantageously arranged between the gripping means, so that on the one hand with the gripping means the cross-sectional shape unified and the ends of the profile rubber sections or the

Rubber profiles are fixed in their position and on the other hand can be done without delay sticking.

In accordance with a further development of the method, a visual impact position detection takes place in which by means of a

Gap widening of the impact-side gap and its contour can be detected. For this purpose, at least one of the two ends of the profile rubber or the profile rubber section is compressed, resulting in the expansion of the shock. This can improve the bonding process. The bonding becomes more reliable and cleaner.

The task will continue through the

Provision of a device for carrying out the method solved. Accordingly, at least one

Two-dimensionally executable adhesive application

available. The adhesive applicator comprises, for example, a brush or a roller or a roller or a cannula, which at least one

Having adhesive outlet opening. The

Adhesive order preparation comes with a

Adhesive feeder and / or an adhesive depot in

Connection .

The feasible cannula with adhesive outlet, the roller or the brush can be glued to the

Transversely cut portions of the cut surfaces of the profile rubbers so that from the Kleberaust openings of the cannula escaping or in or on the brush or in or on the roll befindlicher adhesive on at least one of two cross-sectional oak to be joined can be applied.

According to a preferred embodiment of the invention, at least one adhesive outlet opening is oriented towards one of the cross-sectional areas. With the orientation of at least one Kleberaustrtstsöffnung can

be ensured that a precise application of the adhesive on the cross-sectional areas is possible and thus can be done a reliable and clean bonding.

According to an advantageous embodiment of the invention, the cannula has two opposite, to the

Cross-sectional areas oriented adhesive outlets on. Through the opposite, to the

Cross-sectional oriented adhesive outlet openings can glue on both at the same time

opposite cross-sectional areas of the bonded profile rubber sections are applied.

According to a preferred embodiment of the invention, the device comprises at least one gripping means, wherein the

Gripping means is adapted to hold the profile rubber sections to move toward each other, to press together, to bring in a matching and / or suitable for the adhesive mold. In this case, the gripping means with the ends of the profile rubber or the rubber section in a static contact and for a sense to be understood in this sense adhesion and can thus this

move towards each other and possibly together

to press. The gripping means thus enables an active

Merging and pressing together the

Cross-sectional areas of the two to be glued

Rubber parts. In addition, the gripping means may be shaped so that it forms the ends of the profile rubber or the profile rubber section in a respective matching and / or for the bonding depending on the cross-sectional shapes appropriate form brings by the profile rubber compresses and / or expands accordingly. Thus, even in a relaxed state oval cross-section of the

Profile rubbers are achieved by the gripping means an approximately round cross-section, on which the adhesive is easier to apply in the subsequent bonding process.

According to a development of the device, the at least one gripping means acts on a web connected to the sealing profile of the profile rubber sections. As a web, a region of the profile rubber is called, which performs wall-like without a cavity and as a result is less deformable. Thus, the bridge sets at the same time

Opposition to the pressing against and

accordingly allows a greater stiction. In this way, a gripping means can effectively attach to the rubber profile, without deforming the sealing profile. The web may for example be a connecting web, which is designed as a hollow profile sealing profile with a for

Attachment provided on a motor vehicle door

Adhesive flap connects.

According to one embodiment of the invention, the

at least one gripping means has a central inner contour that matches the outer contour of the sealing profile of the

Profile rubbers corresponds. As a result, a deformation-poor grip around the profile rubber is realized as required. By thus applied to the lateral surface of the sealing profile Gr eifmittelinnenkontur can be realized over a large contact surface, a high friction with minimal deformation of the sealing profile of the profile rubber. In this case, a deformation of the sealing profile of the rubber profile is counteracted to the extent that the rubber profile is brought into a shape and position that ensures an offset-free bonding of both profile rubber sections. These Design is particularly suitable for sealing profiles, which are designed as circular hollow sections.

According to one embodiment of the invention, the Gr eifmittelinnenkontur based on the cross-sectional area of the profile rubber on a small undersize. By a gripping means with a Gr eifmittelinnenkontur, which corresponds to the outer contour of the cross sectional oak and at the same time based on the cross-sectional area has an undersize, can be realized by a uniform force of the gripping means on the sealing profile of the profile rubber stiction or a frictional connection, said the deformation of the cut surface of the tread rubber remains within tolerable limits or as the case may be

Cross-sectional shapes is also wanted. So that can

Cross-sectional areas of both ends of the profile rubbers are glued together precisely and without offset.

According to one embodiment of the invention, the at least one gripping means has at least one suction opening which communicates with the respective surface of the

Profile rubber sections is in operative connection, wherein the suction opening can be acted upon by a negative pressure. This can be done by the concerns of the intake of the

Gripping means on the surface of the profile rubber and the realization of a vacuum, a vacuum adhesion

be realized, the merging and possibly

Compressing the cross-sectional areas of the rubber profile allows.

According to a development of the device are the

Kleberauftragsvorr direction and arranged the gripping means on a working arm connected to a robot arm.

With a robotic arm, the device with cannula and gripping means can be placed according to the splice. The work head, which is free in its orientation, on the one hand makes it possible to start with, for example, the first Cannula the application of the adhesive to be bonded to the cross-sectional oak of the cut surfaces and subsequently by removing, for example, the cannula from the area of the joint or gap to be bonded and the corresponding placement of the gripping means at the ends of the profile rubber, the joining together and possibly compressing the same ,

By, for example, the adhesive is also voragen at the working head as an adhesive depot, the

Process expire faster because the additional process of Klebstoffaufnähme takes place faster and only at longer intervals a refilling of the adhesive depot has to be done. Depending on the adhesive, the structure is simplified.

In particular, in the case of fast-curing adhesives continuous promotion is required, which is ensured by the adhesive supply of the adhesive flow, in which case a regular cleaning of the cannula he has to follow.

On the other hand, the cannula, the brush or the roller is advantageously arranged on the working head in such a way that it is arranged in the region between the gripping means so that even before the adhesive is dispensed

Positional adaptation and / or shape adaptation of the ends of the

Profile rubbers and then the adhesive is applied. For this purpose, the cannula, brush or roller is movably arranged on the working head. This will be a

Process optimization achieved. The orientation of the

Kleberauftragsvorr ichtung and the gripping means is carried out to be bonded to the impact side gap, so that the

Kleberauftragsvorr alignment in alignment or centered to the impact-side gap is arranged. This ensures that in a short sequence of first gripped the profile rubber and possibly in one for gluing

brought advantageous shape and aligned for the congruence. Then be without reorientation or tool change the bonding process carried out and, if necessary, the ends of the profile rubber

pressed together or pressed. By the Kleberauftragsvorr ichtung relative to the working head movable and / or electrically, pneumatically and / or

is hydraulically driven and / or adjustable, is advantageously achieved that the working head, and he is aligned to the vehicle door or driving tool opening, for the processes of gluing relative to the vehicle door or driving tool opening no longer needs to be moved. In example, in a flow operation move the

Working head and the vehicle door or the vehicle worked in or at its openings according to coordinated or synchronously, so that there is no or almost no relative speed between working head and

Vehicle door or vehicle gives. This simplifies and improves the process by avoiding errors or messy culling. Furthermore, movement tolerances are also considerably reduced, since the

comparatively low movement of

Adhesive application in relation to the

Cross-sectional area or adhesive surface is no longer implemented by the robot but in the working head. By driving by means of an electric, pneumatic

and / or hydraulic drive can all

Achieve settings and positions for reliable and qualitative bonding. Advantageous embodiments of the invention will be explained in more detail with reference to the drawings.

Bonding site with a cannula 3 as

Glue Order Preparation shown. Glued are two opposite cross-section oak 1.1 of

Cut surfaces 1 at the ends of a by gluing Closed circumferential profile rubbers 2 and

Profile rubber section 2, with one as round

Hollow profile 1.1 formed sealing profile 1.1 is realized. On the hollow profile 1.1, a web 5 is arranged, which connects the hollow profile 1.1 with a glue flap 10. Between the cross-sectional areas 1.1, which are spaced here, the cannula 3 moves with two opposing Kleberaustr ittsöffnungen 7 on a circular path to the adherend cross-section oak 1.1 of the cut surfaces 1 of the two ends of the profile rubber 2 and

Profile rubber section 2 adhesive (not shown) to apply. The Kleberaustr openings 7 are oriented to the cross-sectional areas 1.1 oriented. Accordingly, by the cannula 3 adhesive on the cross-section oak 1.1 of the cut surfaces 1 is applied. The bonding is carried out by the contact of the adhesive provided with cross-sectional areas 1.1. As the figure 2 shows, the cross-sectional areas 1.1 due to the elasticity of the

Profile rubbers 2 are pressed apart by cannula 3 to apply to the cross-sectional areas 1.1 adhesive. The cannula 3 of the adhesive applicator 3 expresses itself to the adhesive application with its tip between the two cross-sectional areas 1.1 at the cut surfaces 1 at the ends of the profile rubber 2 and profile rubber section 2. After pulling out the cannula 3 are the

Cross sections 1.1 by the elasticity of the

Profile rubbers 2 again pressed together and thus stick together. FIG. 3 shows a sectional surface view with a gripping means 4. The profile rubber 2 is shown in FIG. 1

known profile rubber 1 with a hollow profile 1.1, which is connected by a web 5 with a glue flap 10. The adhesive tab 10 is attached to a door 11 of a car with a double-sided adhesive tape. Accordingly, the bonding of the rubber profile 2 after gluing on the door 11 and the door frame done. In order to securely assemble the two sections of the profile rubber 2 after the application of the adhesive, here is a gripping means 4, each consisting of two movable parts, with the gripping elements 4a, 4b which surrounds the hollow profile 1.1 of the profile rubber 2.

The arcuate part of the grease element 4a

encloses the circumference of the hollow profile 1.1, wherein the

Grof element 4a abuts one side of the web 5. A straight section of the gripping element 4b presses against the other side of the web 5. Thus, the web 5 can be clamped by the two gripping elements 4a, 4b of the gripping means 4. Accordingly, a static friction between the grease elements 4a, 4b and the web 5 is effected so that a force perpendicular to the plane of the drawing can be exerted on the profiled rubber 2 via the gripping means 4. Thus, the two cross-section oak 1.1 of the cut surfaces 1 of the ends to be bonded

Profile rubber sections 2 are pressed together for bonding.

The arcuate part of the central element 4a has a central inner contour 6, which corresponds to the lateral surface and thus to the outer contour of the cross section 1.1. Thus, the profile rubber 2 is located at the

Green inner contour 6. This can be done by the

arcuate part of the Griif element 4a, the position of the profile rubber 2 fixed and optionally also be corrected to allow an offset-free bonding.

In Figure 4 is a view of a cross section of oak eiches 1.1 a sectional area 1 with a section through an alternatively formed gripping means 4 is shown. In this example, sectional area 1 and cross sectional oak 1.1 are the

Profile rubbers 2 identical. The pincer-like gripping means 4 has on the inside a rough inner contour 6, which coincides with the lateral surface and thus with the outer contour of the respective

Cross sectional areas 1.1 of the profile rubber sections 2 corresponds. Thus, the respective

Profile rubber section 2 embraced and slightly

be pressed together to realize a stiction between profile rubber 2 and gripping means 4. Due to the shape-limiting gripping means inner contour 6, which has a small undersize relative to the outer contour of the respective cross-sectioned oak 1.1 of the profile rubber section 2, the compression takes place with little deformation. This can be realized between gripping means 4 and profile rubber 2 a stiction. Accordingly, the profile rubber 2 can be moved by the gripping means 4 perpendicular to the plane of the drawing for a compression or pressing together the ends of the profile rubber 2 in the required dimensions.

Furthermore, suction openings 12 are arranged here in the gripping means 4 on the inside, which correspond to the outer contour of the profile rubber 2 to the effect that a

Suction is reliably possible. By creating a

Underpressure to the suction openings 12, preferably by a corresponding embodiment of the gripping means 4 with a cavity, the profile rubber 2 from the gripping means. 4

sucked and thus generates a corresponding static friction and supported. As a result, can be moved towards each other by the gripping means 4, the two sections of the rubber profile 2 and possibly pressed together.

FIG. 5 shows a side view of a working head 9 with cannula 3 as an adhesive application device 3 and

Gripping means 4 for bonding the ends of a profile rubber (not shown). The cannula 3 as

Adhesive application 3 is used to supply the

Adhesive application on the cross-sectional areas of Cut surfaces (not shown) make. The

Gripping means 4, which after the adhesive application to the

Adhesive is moved, allows the pressing together of the two to be bonded cross-sectional oak oak of the ends of the respective rubber profile or profile rubber section. The working head 9 is attached to a robot arm 8, with which it can be moved to the splice. Characterized in that the working head 9 is rotatably mounted on the robot arm 8, according to the requirements, the cannula 3 and subsequently, as shown here, the gripping means 4 for

Glueing the profile rubber or rubber section on the door 11 are rotated.

FIG. 6 shows a concrete embodiment of a cannula 3 with a lateral adhesive outlet opening 7 in FIG

Perspective view shown.

FIG. 7 is a perspective view of one

Bonding point between the ends of a profile rubber section 2 shown in sections. The

abutting gap between the two ends of the

Profile rubber section 2 form the two

Cross sectional areas 1.1 of the cut surfaces 1 of

Profile rubber section 2. On one or both of the adhesive surfaces 1.1 serving as cross-sectional areas 1.1 3 adhesive is applied by means of the cannula. For this purpose, the two-dimensional feasible in the specific embodiment cannula 3 is moved so that the Kleberaustr ittsöffnung (not visible) along the or the cross-sectional areas 1.1 of the profile rubber sections 2 are performed.

After the adhesive application on the

Cross sectional areas 1.1, the profile rubber sections 2 are moved towards each other and, if necessary. pressed together. The bonding takes place for example when using superglue within 3 to 9 seconds. The

Moving on one another can be passive due to the elasticity of the body Profile rubbers 2, as shown in Fig. 2, take place. The active merging is carried out by a gripping means 4 with the existing depending on the design Gr eifmittelelementen4a, 4b, which is shown in a specific embodiment in Figures 8 to 12 in different views.

FIGS. 8 to 12 will be described coherently below, reference being made in the details to the figures in which they are particularly clearly recognizable. The grease elements 4a, 4b are designed to be able to hold one of the two profile rubber sections 2 to be joined together by static friction, as can be seen clearly in FIG

Adhesive application both profile rubber sections 2 by

Moving the gripping means 4 in the longitudinal direction of

Profile rubber sections 2 at the cross-sectional areas merge 1.1 and cause a sticking.

FIG. 8 shows an opened gripping means 4 with a movable gripping element 4b and an on

fixed profile element 4a abutting profile rubber 2 and a profile rubber 2 in a view in the longitudinal direction and with a view of the cut surfaces 1 of the profile rubber 2. The profile rubber 2 is a hollow 1.1

executed sealing profile 1.1 realized. The hollow profile 1.1 is connected by a web 5 with a glue flap 10. By the adhesive flap 10 of the rubber profile 2 is glued here with a door 11 of a motor vehicle to seal it against the body. The bonding of the two

Profile rubber sections 2 are preferably joined together after gluing the adhesive flap 10 of the profile rubber 2 to the door 11. After adhesive application by means of a cannula 3 as adhesive application device 3, as shown in FIG. 7, the gripping means 4 engages the profile rubber by means of the central elements 4a, 4b 2, which here bears against the profiled rubber 2 on the outer contour of the profiled rubber 2, which corresponds to the outer contour of the profiled rubber 2. Through a grease cylinder 13, the movable grease element 4b of FIG

Gripping means 4 is moved to the profile rubber 2. Ultimately, the movable element 4b of the

Gripping means 4 against the web 5 of the rubber profile 2 and thus allows a holding of the rubber profile 2 and thus allows a corresponding displacement in the longitudinal direction of the rubber profile 2. Since the web 5 in contrast to

Cross section 1.1 of the profile rubber when

Pushing the gripping means elements 4a, 4b of the

If the gripping means 4 is hardly deformed, the movable gripping element 4b can press here with a sufficiently high force against the web 5 held by the stationary gripping element 4a of the gripping means 4. The

Guiding the movable gripping element 4b of the

Gripping means 4 takes place here by guide plates 14, which specify the direction of displacement with introduced slots. Here, the direction of displacement is angled to

Gr oifmittelzylinder 13 oriented. The

Grain inner contours 6 of the grease elements 4a, 4b also ensure a dimensionally stable and offset-free

Alignment of the profile rubber sections 2 to each other, as clearly visible in Figure 10.

FIG. 11 shows that known from FIGS

Arrangement of the gripping means 4a, 4b in one

Perspective view. It differs from the Fig. 10 in that here the bonded profile rubber sections 2 are not shown. It can be seen that the stationary grease elements 4a of the gripping means 4 or their proportionate grain inner contour 6 extend approximately over half the width of the profiled rubber 2. The shaping or cross-section for a

unified, suitable for the bonding form takes place here only partially. Closing the gripping means 4 leads to a holding and to a further shaping or

Cross-section. Another embodiment of the device for carrying out the method is shown in FIGS. 12 to 17. Here, the Kleberauftragsvorr direction 3, in the specific embodiment with a cannula 3, arranged on the working head 9 between two gripping means 4. The cannula 3 is in this case arranged relatively movable to the working head 9. For this purpose, a movement device 16 with two

rotatable drive wheels 17, which via a

Drive belt 18 is connected and, for example via a pneumatic drive 21 by engaging in the

Drive belts are driven, available. With both drive wheels 17 a push rod 19 is still connected. The push rod 19 is arranged eccentrically on the drive wheels 17 movable. To the

Push rod 19 is still the

Kleberauftragsvorr direction 3 arranged with, for example, the cannula 3. Due to the eccentric arrangement of

Push rod 19 describes the Kleberaustr opening 7 of the cannula3 of Kleberauftragsvorr direction 3 also a circular path, which the cross-section of oak 1.1 of

Adhesive surface 1.1 on the cut surface 1 at the two ends of the profile rubber 2 corresponds. In addition, the

Moving device 16 with the drive wheels 17, the push rod 19, the drive belt 18, the

Kleberauftragsvorr ichtung 3 and the pneumatic drive 21 linear in the alignment of the Kleberauftragsvorr 3 so towards the profile rubber 2 and again away from the profile rubber 2 slidably. Thus, a movement is achieved across the profile of the rubber profile. This movement is achieved with a pneumatic drive 20. The linear movement or linear movement allows the application of adhesive to at least approximately rectilinear courses of the

Cross section 1.1 of the adhesive surface 1.1.

In Fig. 12, the working head 9 is a concrete

Embodiment shown. Between the gripping means 4 Kleberauftragsvorr the direction 3 is arranged. The Adhesive application 3 is as described above on

Moving device 16 is arranged. This working head can be easily attached to robots or with robots

use and for this purpose also at the respective

Arrange robot arm.

In FIG. 13, the gripping means 4 surround a profiled rubber 2. The cannula 3 of the adhesive applicator 3 is already in the impact-side gap and carries the adhesive onto the gripper

Cross section 1.1 of the cut surface 1 as an adhesive surface 1.1.

FIG. 14 shows a detailed view of the gripping means 4 and the adhesive application device 3 arranged therebetween at the end of which the cannula 3 can be seen. It can also be seen that, as also detailed in FIG

the fixed gripping element 4a of the respective gripping means 4, in particular in the central area of the arrangement, ie in the region of the ends of the profiled rubber 2 or in the region of the adhesive application 3 over the entire width of the profiled rubber 2 or over the entire width of the gripper inner contour 6 arc

is trained. Thus, in particular the profile rubber 2 in the region of the bond by the gripping means 4 of

Cross section 1.1 in the allowable and justifiable extent in a favorable for the bonding and for the movement of Kleberauftragsvorr 3 form, for example, a circular shape, without compressing the profile rubber 2 unfavorable. Depending on the circumstances and situation, it may not be necessary for the gripping means 4 to grasp and hold the rubber profile 2. It may already be sufficient for the stationary center element 4a to press against the profile rubber 2 and to press the section rubber 2 into the desired or required shape due to the counter-pressure of the vehicle door 11, which is shown for example in FIG. However, for a short process time and a high-quality bonding, it is also conceivable that the gripping means 4 embrace the rubber profile 2 and the profile rubber sections 2 and hold. The shape would be respectively

guaranteed. FIG. 16 also shows the movement device 16 as described above and schematically the pneumatic drive 20 for the linear movement of the movement device 16. In the upper part of the representation of the

Cross section 1.1 of the profile rubber 2 keep the adhesive flap 10 is a straight course in

Cross section 1.1. This area is characterized by the rectilinear motion or linear motion of the

Moving device 16 traced and the adhesive is done reliably. Subsequently, a

Pivoting movement by the moving device 16 and the downwardly facing arcuate portion of the

Cross section 1.1 of the profile rubber 2 is

traced and the adhesive is applied here also reliable following the contour. In FIG. 16 are

schematically the movements for each of the

Linear movement of the moving device 16 with the

pneumatic drive 21, which causes the pneumatic drive 20, and in Figures 16 and 17, the movement of the cannula 3 of Kleberauftragsvorr direction 3 along the contour of the cross-sectional area 1.1, which the pneumatic

Drive 21 in conjunction with the movement device 16 causes, with movement arrows or directional arrows

shown. According to this concrete

Movement sequence is achieved that the cannula 3 of Kleberauftragsvorr direction 3 preferably no or only a very small area of the cross-section of oak 1.1 the adhesive surface 1.1 repeatedly passes over or sweeps. When several times crossed over individual areas of the adhesive surface 1.1 would be achieved disadvantageously that the cannula 3 would possibly strip the applied adhesive again. A soiling of the cannula and thus a

regular, time-consuming and material-intensive cleaning would be the result and can be at least reduced in the exemplary sequence of movements. In addition, the adhesive surface and the adjacent areas would be contaminated and the impact-side Profilgummiverklebung would be of poor quality.

In a specific embodiment according to FIG. 16, the movement device 16 can be displaced linearly in the direction of the profile rubber 2 or in the direction of the cut surfaces 1 to be glued. By means of the pneumatic drive 20 as Linearantr sieve the entire movement device 16 in the direction of the impact side gap and during bonding or when applying adhesive to the cross-section oak 1.1 as adhesive surface 1.1. also moved into this or moved into it. During this linear movement, according to the specific illustration in FIG. 16, the contour of the rubber profile 2 is applied to the upper rectilinear section of the cross section 1.1 of the profile rubber, and the cannula protrudes between the ends of the profile rubber 2. When the rectilinear region has traveled, the circular-arc-shaped region of the transverse cutting region 1.1 follows the contour of the

Profile rubbers 2. This area takes over the

Movement device 16. To achieve this

Motion sequence includes the movement device 16 according to the specific embodiment in Figure 16 as described above drive wheels 17, a drive belt 18, a push rod 19 and a pneumatic drive 21. Thus, the drive belt 18 is a toothed belt 18. The drive wheels 17 are corresponding to the timing belt compatible gears 17th The push linkage 19 is arranged on these drive wheels 17 so as to be concentric and aligned with respect to the circumference so as to be rotatable so that the rotational movement of the drive wheels 17 is comparable to a rod drive, the drive wheels 17 via the toothed belt and a pneumatic drive 21 driving the toothed belt 21 be driven by pneumatic cylinder. By the typical linear motion of a pneumatic cylinder is on the one hand by means of the pneumatic drive 21 a forward movement completed, which is a circular arc-like movement of the cannula 3, according to the contour of the

Cross section 1.1 of the adhesive surface 1.1 performs. If the adhesive application after complete, according to the contour of the cross-sectional area 1.1 of the adhesive surface 1.1 following movement of the cannula 3 is completed, moves

Moving device 16 by means of the pneumatic drive 20 back away from the bonded rubber profile. Now, on the other hand, the reverse movement of the linear movement of the pneumatic drive 21 for returning the cannula 3 in the initial position. Here, the cannula 3 moves outside the adhesive surface or spaced from the bonded profile rubber 2 back is the starting position and performs the

circular arc-like movement in the reverse direction.
