A problem of this application device is that the handling, for example when refilling the fabric components and when using the device with only a part of the filled material components, becomes difficult.

Presentation of the invention

It is therefore an object of the invention to provide an application device for multi-component materials, which is improved in terms of handling when refilling the fabric components and only partial consumption of the fabric components.

This object is solved by the features of independent claim 1. Advantageous developments of the invention are the subject of the subordinate claims.

The inventors have recognized that the handling of such an application device can be substantially improved if the device can be loaded from the front, ie from the discharge side, at least with respect to a substance component, preferably with respect to all substance components. This requires the presence of a cover adapter on the side of the cartridge receiving device of the application device to which a cartridge cover can be fastened, to which in turn a mixing device can be fastened. By this training, on the one hand, the refilling of the fabric components can be done very easily, without having to explode a Austriebsvorrichtung for the fabric components, which optionally has an electric drive with a complex gearbox. As a result of the problem-free removal of the mixer, after a partial use of the substance components, the mixer in which the already mixed components have cured can be exchanged in a simple manner and the application can be carried out with the remainder of the substance components.

Part of the invention is also inventively configured refill and cartridge set of a combination of a first cartridge of a cylindrical tubular packaging with a fabric component, a second smaller cylindrical cartridge with a solid outer wall and a connecting element of both cartridges, which is designed so that the entire package can be inserted from the front into the cartridge receiving devices and is ready for immediate use.

• eine Mischvorrichtung, welche mit den Komponentenausgängen verbunden ist, die ausgetriebenen Stoffkomponenten mischt und diese gemischt austrägt,
• mindestens eine der Kartuschenaufnahmevorrichtungen zur austragsseitigen Beladung mit Kartuschen ausgebildet ist,
• mindestens eine der Kartuschenaufnahmevorrichtungen zur Halterung einer Kartusche mit fester Außenwand ausgebildet ist,
• austragseitig an den mindestens zwei Kartuschenaufnahmevorrichtungen ein Deckeladapter vorgesehen ist, und
• ein Kartuschendeckel vorgesehen ist, welcher erfindungsgemäß zur Aufnahme oder Anbringung der auswechselbaren Mischvorrichtung ausgebildet ist.

According to the main aspect of the invention, the inventors propose an application device for multi-component materials, in particular multi-component adhesives or multi-component sealants, which has the following features:

• at least two contiguous cartridge receiving devices for receiving replaceable cartridges with substance components to be mixed,
• a expulsion device for the simultaneous expulsion of the substance components from the cartridges in predetermined proportions by component outlets with the aid of sprouting pistons,
• a mixing device which is connected to the component outlets, mixes the expelled substance components and discharges them mixed,
• at least one of the cartridge receiving devices is designed for discharge-side loading with cartridges,
• at least one of the cartridge receiving devices is designed to hold a cartridge with a fixed outer wall,
• on the delivery side of the at least two cartridge receiving devices, a cover adapter is provided, and
• a cartridge cover is provided, which is designed according to the invention for receiving or attaching the interchangeable mixing device.

In a particularly favorable embodiment, an active mixer can be used as a mixing device, wherein preferably a drive axle is provided for the active mixer, which drives the active mixer, for example, on the basis of the same electric drive, which also takes over the expulsion of the material components. Here, a transmission can be used which has a plurality of drive outputs, wherein one of the outputs is designed to drive the mixer. in this connection the cover adapter should have a passage for the drive axle from the gearbox to the active mixer. Likewise, then also the cartridge cover should have a passage for this drive axle to the active mixer. Alternatively, a passive mixer can also be used as the mixing device.

A closure device is provided which securely secures or stores the cartridges used in the cartridge receiving devices.

In a first non-inventive example, a closure clip can be provided for this purpose, which fixes the cartridge cover after placing the cartridge cover on the cover adapter. In a particularly stable embodiment, the closure bar can have two pivot axes, which are articulated in the area of a cartridge receiving device.

A second non-inventive example is that the cover adapter is provided with a screw cap which has a thread which can engage in a counter thread, preferably a counter thread segment, on the cartridge cover. It is advantageous if the screw has an external thread and the cartridge cover as a mating thread has an internal thread.

As an alternative to the screw cap, a bayonet catch can also be used, which has a pivotable about a rotation angle engagement, which can engage in a counterpart on the cartridge cover.

According to the invention, the cartridge cover is also mounted pivotably about a, in particular for the longitudinal axes of the cartridge receiving devices, pivot axis on the cover adapter, the cartridge cover itself should have a locking mechanism, which should prevent accidental opening of the cartridge cover. For example, this may be a clip closure or a latch or something similar. Furthermore, it is proposed that, according to the invention, an axis displacement element is mounted which can displace at least a part of the optionally telescopically formed drive axis of an existing active mixer in the axial direction. As a result, the insertion of an active mixer is much easier.

Another non-inventive example of the application device provides as a closure device that the cartridge cover a plurality of elastic claws in the form of clip closures and the lid adapter has at least one corresponding counterpart, so that when placing the cartridge cover on the lid adapter, the jaws can engage.

In this case, in addition, a closure sleeve can be provided, which can be pushed over the jaws to secure the connection between the lid adapter and the cartridge cover. It is advantageous if the elastic claws are configured without loading with a bend to the outside, so that they engage only with the sliding over the closure sleeve or automatically disengage when pushing back the closure sleeve and release the cartridge cover again.

For easy attachment of the mixing device, the cartridge cover may have a mixer adapter into which the mixing device can be inserted and secured. Preferably, a bayonet closure or a screw cap can be used to secure the mixing device.

A not to be underestimated share of the ease of handling of the application device according to the invention for multi-component materials, in particular multi-component adhesives or multi-component sealants, is the simple loading of the fabric components, wherein these should be arranged according to the invention and assembled in a cartridge set according to claim 6.

In a possible use of an active mixer, the adapter piece should preferably have an opening for a drive axle.

Furthermore, in the case of the cartridge set, the second receptacle can have a centrally located opening through which a discharge spout of the second cartridge can be inserted.

A favorable arrangement of the cartridge set is also when the centers of the opening for an opening device of the tubular bag, the opening for the drive axis and the opening for the discharge spout of the second cartridge are arranged in a projection from the front on a straight line.

In addition, it is advantageous to avoid unnecessary free space, which can cause problems in the dosing accuracy, when the first receptacle has a centrally located bulge, which provides space for a closure piece of the tubular bag.

Finally, in the context of the present invention, a packaging unit according to claim 7 is proposed.

Ways to carry out the invention

The FIG. 1 shows a first variant of a non-inventive application device 1 with a possibility for loading the cartridge receiving devices 2.1 and 2.2 from the front or from the application side. Shown is the application device in this illustration without the drive device with which ultimately the arranged in the cartridge receiving devices 2.1 and 2.2 fabric components are expelled. In the present illustration, the application device 1 comprises a first cartridge receiving device 2.1 for a tubular bag, while the cartridge receiving device 2.2, which consists essentially of two cylindrical support tubes, is provided for introducing a cylindrical cartridge having a fixed outer wall. The application device 1 is configured such that for loading the application device 1 with two different substance components a cartridge set 3, consisting of a tubular bag 3.1 and a cartridge 3.2 with a fixed outer wall, is provided. Both cartridges 3.1 and 3.2 are held together by means of an adapter 3.3 in the correct positioning, so that the entire cartridge set 3 can be inserted into the cartridge receiving devices 2.1 and 2.2 with a handle.

It should be noted that the first cartridge receiving device of the application device is designed specifically for receiving a tubular bag, that is approximately as in the embodiment according to Fig. 1 as a self-supporting cylinder with a fixed outer wall, while the second cartridge receiving device is designed for insertion of a self-supporting cartridge with a fixed outer wall. The adapted receiving device must support and support such a cartridge only in the front region and therefore preferably does not comprise an (additional) cylinder extending over the cartridge length. Incidentally, the adapter attached to the cartridges already exerts a certain support and holding function for the cartridges.

Subsequently, the cartridge cover 4 is placed on the front-mounted cover adapter 2.3 and locked by means of a bracket 8, which is articulated via two pivot axes 8.1 and 8.2 on the cartridge receiving device 2.1, by folding down this shutter bracket to the cover flange 4.1. The cover adapter 2.3 is designed so that when using an active mixer, as shown in the FIG. 1 is shown, the drive axle 9 is passed through the adapter 3.3 on the one hand and on the other hand, the lid 4 leaves enough space to connect the drive shaft 9 with the active mixer 5. If the cover 4 is attached to the cover adapter 2.3, then the active mixer 5 can be inserted into the mixer adapter 4.2 of the cartridge cover 4. Previously, the two cartridges were opened, so that after actuation of the drive device not shown here, the two components from the two cartridges 3.1 and 3.2 are supplied in the desired dosage to the active mixer 5, which is operated simultaneously by means of the drive shaft 9. For attachment of the active mixer 5 on the cartridge cover 4 is in the present case, a bayonet closure. 6 provided, which is placed over the active mixer 5 and this fixed in the mixer adapter 4.2 of the cartridge cover 4. The active mixer 5 also has an application tip 7, through which the mixed substance components from the cartridges 3.1 and 3.2 can be applied in the desired manner.

The FIG. 2 also shows a non-inventive application device 1, which can be loaded with a cartridge set 3 from the application side, in which embodiment the cartridge cover 4 by means of a screw 10 with an external thread 10.1 to the cartridge receiving devices 2.1 and 2.2 can be screwed, wherein the Cartridge cover 4 inside a thread segment 4.6 not visible here, which is not completely closed, so that the cartridge set 3 can be used while with the help of the screw cap 10 of the cartridge cover 4 is screwed to the cartridge receiving devices 2.1 and 2.2.

In the illustrated embodiment it can be seen that in contrast to the execution of the FIG. 1 the cartridge receiving device consists of a single cylindrical insert, but compared to the embodiment in the FIG. 1 is formed much longer. The attachment of the active mixer 5 shown here takes place according to the description FIG. 1 , wherein it should be noted that not necessarily an active mixer must be used, but also passive mixers in the application device 1 can be used.

Furthermore, instead of the screw cap 10, which is here designed with an external thread 10.1, a bayonet catch 6 are used, which engages on the opposite side of the cartridge cover 4 in corresponding recesses and by turning a few degrees the cartridge cover 4 to the cartridge receiving devices 2.1 and 2.2 attached. It should also be noted that the bayonet lock 6 shown here can also be replaced by a screw cap in which the mixer adapter 4.2 a corresponding external thread is arranged and the rotary closure 6 has a matching internal thread.

An inventive application device 1 is in the FIG. 3 shown. This application device 1 is designed with the cartridge set 3 loaded from the front, for this purpose in the embodiment shown a cartridge cover 4 is used, which is articulated on one side to a not visible here pivot axis on the cover adapter 2.3, so that for opening the application device 1 of Cover 4 is swung laterally about this pivot axis. Subsequently, the cartridge set 3 can be used and then the cartridge cover 4 pivoted about the inserted cartridge set 3 and this closed it. To secure the cartridge cover 4, a clip closure 4.5 is provided, which can engage on a counterpart on the cover adapter 2.3. If the application device 1, shown here with an active mixer 5, operated, so located between the two cartridge receiving devices 2.1 and 2.2, the drive shaft 9, which in a particularly advantageous embodiment - as shown here with the aid of an axis shift element 2.4 - due to their telescopic training with respect the front end can be moved to the rear, so that the cartridge cover 4 can be easily pivoted. If the cartridge cover 4 is closed, the telescopically formed tip of the drive axle 9 can be pushed forward again with the aid of the axle displacement element 2.4 so that it can engage in the active mixer 5 as soon as it is inserted in the mixer adapter 4.2.

In the Figures 4, 5 and 5a is again another non-inventive variant of an application device in the area of the cartridge cover shown, the cartridge cover 4 in this case for attachment to the cover adapter 2.3 has several claws 4.3, which can engage in a counterpart 2.5 on the cover adapter 2.3. Basically, these claws can be designed so that they automatically engage in this counterpart 2.5 when placing the cartridge cover 4. In the shown here However, these are slightly bent outwards, so that a latching takes place only after a rightward displacement of the closure sleeve 4.4, which rotates the cartridge cover 4 and when you move the right claws 4.3 engage in the counterpart 2.5 of the lid adapter 2.3.

Such a situation with pushed to the right or pushed backward locking sleeve 4.4 is in the FIG. 5 shown. In particular, in the detailed representation of FIG. 5a can be seen in section, as the claws 4.3 engage in the counterpart 2.5 on the side of the cover adapter 2.3 by the pushed backward locking sleeve 4.4.

In the FIG. 6 For a better understanding of the refill this is shown enlarged again. It consists of a first cartridge 3.1, which is designed as a tubular bag, and on both sides each having a closure piece 3.4. This tubular bag 3.1 is inserted on its front side into a first receptacle 3.5 of the adapter 3.3, this first receptacle 3.5 having a forwardly directed bulge 3.7, which provides space for the closure piece 3.4. As a result, the tubular bag 3.1 can be easily inserted into the first receptacle 3.5 without unnecessary space to form. It may be advantageous in this case if, in addition, the tubular bag 3.1 is glued to the receptacle 3.5, so that the adapter 3.3 forms a unit with the tubular bag 3.1. Correspondingly, the adapter 3.3 also has a second receptacle 3.6 into which the cylindrical second cartridge 3.2 is inserted, this receptacle 3.6 having a central opening 3.11, through which the discharge nozzle 3.12 of the cartridge 3.2 protrudes.

The two shots 3.5 and 3.6 are connected by means of two webs 3.9 and have in the area between the shots 3.5 and 3.6 via an additional guide with a breakthrough 3.10 for the drive axis of an active mixer. It should be noted that the presence of this breakthrough 3.10 is optional, whereby when using a passive mixer a corresponding Drive axle is not necessary.

In the embodiment shown here, the center points of the outlet opening 3.8 for the substance component of the tubular bag 3.1 and the discharge nozzle 3.12 of the second cartridge 3.2 and the center of the opening 3.10 for a drive axis of the mixer are therefore in line with one another. In addition, the center of the bulge 3.7 is also on the same line.

In FIG. 7 the above-mentioned non-inventive variant of the application device with bayonet lock is shown, wherein the cartridge cover 4 for attachment to the cover adapter 2.3 distributed over several circumferentially formed L-shaped extensions 4.7 has, in a bayonet fitting counterpart 11 on the cover adapter 2.3 can intervene. Apart from the slightly different shaped and longer cartridge receiving device 2.2. Incidentally, for the cartridge 3.2, this embodiment substantially corresponds to the embodiments described above.

It should be noted that in such an application device in a known manner, a drive device is provided, and can be operated with this. For example, the drive device of at least one transmission and an associated electric motor, which is responsible for the power drive of the entire transmission consist.
