Description

Device for mixing and applying two-component putty D @ e The invention relates to a device for mixing and applying two-component putty, which are particularly suitable for repairing and cementing natural and artificial stone is.

The application of two-component putty or glue continues in practice more and more. This is due to the high strength values and other special properties can only be achieved if you use the respective Glue or putty as such does not need to be stored and the individual components only mixed with one another on the spot immediately before consumption. At the Gluing artificial and natural stone or when repairing stones is in the Usually the procedure is to put the two in a container or on a plate Mixes components together and then brings them to order.

However, this mixing is not as problem-free as it is at first may seem, because the mixing ratio must be adhered to fairly precisely and the hardening paste only has a relatively small proportion, i.e. it is allowed can only be added within the limits of two to four percent of the total mass, if on the one hand, good adhesion and, on the other hand, no deterioration in quality occurs target. Even slight percentage changes affect the quality of the putty extremely unfavorable. Too high an addition of hardening paste can not only lead to Cracks or the like .. lead, but it also brings discoloration of brown to pink with it, what with cementing or gluing in the field of vision is disruptive and has to be rejected from a technical point of view. Another difficulty is in it to see that the hardening paste contains peroxide, so dangerous for eyes and soft tissues is. Quite apart from these disadvantages, mixing by hand is also uneconomical, especially since it not only takes a relatively long time, but also leads to leftovers, which are unusually hard after a short time and are therefore regarded as lost have to. Last but not least, mixing as such also causes difficulties the individual components, in particular the actual putty, are usually in large containers is located, the handling is difficult and tiring.

The already mentioned relatively large expenditure of time is based, among other things, on also on the fact that great care must be taken when mixing by hand, if high quality cement or the like. are required In contrast The invention aims at a device which initially mixes two components for a putty or the like. Allowed time-saving and without danger for the person carrying out the work. Another requirement is that the prescribed mixing ratios can be adhered to extremely precisely without it being cumbersome and sources of error does not require exclusive dosing work.

Furthermore, it should be possible with the new device that for Mixing certain substances sparingly and avoiding useless residues. It is also part of the object of the invention that the device is functionally reliable works and work interruptions without the risk of losing time and material allows. Finally, the handling of the device and working with it should be be simple and convenient, with all of these requirements as low as possible economic effort should be achievable.

According to the invention, this aim is mainly achieved by that the device is elongated, preferably square in cross section Has storage space, which merges into a mixing nozzle at the front end and is exchangeable has two compressible storage containers for the two cement components, the ends of the container from the rear under the influence of a displacement part stand in the form of a roller or a wedge. First of all, it should be pointed out as advantageous that by the device the Mlschen the both components one undergoes a certain automation, which consists in the fact that the displacer part in terms of content coordinated storage containers so loaded that the two components Enter the mixing nozzle in portions, i.e. in a percentage matched to one another and there they are mixed together to a sufficient degree. Then the two Components packed in the storage containers in the correct ratio to one another the highest level of quality is achieved with cementing or gluing, due to the correct dosage, there are no discolouration-related disturbing phenomena are to be feared. In addition, the device saves considerable working time, quite apart from the fact that the handling of the device is very easy, there in addition to the usual cleaning work, only the storage containers of time have to be replaced or renewed from time to time. The device according to the invention but also enables an immediate start to work and, as already indicated, avoids unfavorably significant residues. In any case, with the inventive Device also adhere to tight mixing tolerances, which is often required and indispensable is.

Finally, it should be mentioned that, despite the numerous advantages, the Device remains simple and as a whole does not require a great deal of economic outlay requires.

According to a further special feature of the invention it is provided that in the case of a roller as a displacer part this in two lateral slits of the storage room is rotatably guided and a radial slot for Inclusion of Has storage container ends. This design is comparable to squeezing out a tube, in which the empty end is easily wound up. In any case, there is a repression with a radial slot a simple construction element that is neither functional, still presents manufacturing difficulties. The slot version closes but not from the fact that the displacement part is designed as a squeegee roller when Turning with a toothed shaft on side racks and unrolls the containers presses against a wall of the storage room. So here is with the roller and the racks the contents of the containers are pushed forward into the mixing nozzle, in turn the extraordinarily simple structure stands out. But it is just as easy if with a wedge as a displacer part this on one the containers against one Wall of the storage space pressing sliding piece is provided, which in the axial direction under. the influence of a spindle, a hydraulic or pneumatic working cylinder, a toothed ratchet or the like. stands. This remedy is very simple to train and guarantees that the components are pressed out without leaving any residue.

So that the respective displacer part of the storage container when pressed together can not damage, it is provided according to the invention that between the displacement part and the immediately adjacent storage container a spring band is provided that extends in the upper area of the storage space from front to back and backwards Pulled in a flat S-loop near the bottom under the respective displacer part is. This band can be made from thin spring steel: or but also made of abrasion-resistant and plastic with spring properties. In any case, that educates Tape a touch lock so that the respective storage container from the displacer there is no risk of pulling out due to friction.

According to the invention, it is also considered appropriate that the rear end of the storage space with a flap, a lid, a slide Od. Like. Can be closed, the respective closure part as an abutment for those means, e.g. for a spindle, are used, which are used for the storage containers load effective sliding piece. The removability of the closure part allows a quick exchange of the containers by opening the closure part and pulling it out or is otherwise released from the storage space. It goes without saying that the closure part Performs relatively strong to ensure a secure support of the respective pressure medium to achieve.

Since two-component putties are mixed relatively quickly become rock hard, comes the cleaning possibility of the device and in particular particular importance to the nozzle. For this purpose it is provided according to the invention, that on the front end of the storage space the mixing nozzle with incorporated mixing zone is placed like a funnel and fastened to the storage room by means of clamping hooks. It it is understandable that the nozzle sits sufficiently sealed on the storage container and thereby forms a unit with this. Let by removing the nozzle themselves the interiors by rinsing or immersion in solvents or putty remover, such as methylene chloride very easy to clean. Besides, it's easy to get around any parts that may have been inserted into the nozzle. Replacing and attaching the nozzle on the storage container by means of the clamping hook means no difficulties. Instead of the closed mixing nozzle, it is possible according to the invention that at the The upper and lower edge of the front end of the storage space are each hinged to a flap is that folded up, sealed against each other and secured against each other form the mixing nozzle with a mixing zone. It's even easier to get through these flaps into the inside of the mixing nozzle and can easily remove the parts with a putty remover clean.

With this nozzle design, however, one has to seal more areas.

Since the respective displacer has a considerable thrust on the Exercises storage containers and their contents, it appears according to the invention of Advantage that the front end of the storage space is closed with a solid support wall is, which leaves a slot-gap at the bottom, to which the mixing zone has the same cross-section and flowing adjoins and in the further exit parts of the storage containers reach in. The supporting wall offers the containers a sufficient abutment, without endangering the escape of the pasty or viscous masses; on the contrary, through the slot-gap and through special measures -n the containers themselves the two components come into the mixing zone in the right amount, namely about @ after de @ Stüttwand, there how gie invention provides exit parts the storage containers push through the Schiitz gap, the solid support wall also allows greater pressures on the displacement part, so that the mixed components proportionately will emerge quickly from the nozzle, so high working speeds are possible are.

To achieve an intense intermingling of de; to achieve both components, It is also considered expedient according to the invention that the mixing zone with transversely to the direction of flow of the two components arranged, preferably with a comb-like shape from below and above interlocking or gap-set pins is. The component flow is, so to speak, divided many times by the pins and led again and again changing direction, so that when exiting the nozzle on In any case, the two components are perfectly mixed.

Another special feature of the invention is that the pins sit on plates that are on the inner upper and lower surface of the mixing nozzle in the direction of flow of the two components in lateral guides, e.g. interchangeable in rail-groove guides are held.

This measure is of great importance to the extent that it is intended and unintentional work breaks after opening the flaps or removing the Jet the plates with the pens effortlessly and quickly removed and into a putty remover Can be placed where they are from the component scraps that may look hard become liberated. In general, one becomes the removed panels Replace with another Pa @ r plates in order to be ready again immediately and those already used Plates in the putty remover solution for cleaning place. Last but not least, this quick change of the plates also allows use the simple strip-groove connection.

With regard to the handling of the entire device and with consideration ensure that the insertable plates can be easily removed with their pins, it is advantageous according to the invention that the mixing nozzle (18) or

the two flaps, seen from above, one forward in width have decreasing conical shape.

If you want to carry out filling work with the device, we recommend it is that a spatula plate can be placed on the upper flap, which the nozzle surmounted to the sides and to the front. It goes without saying that the spatula easily detachable and possibly adjustable, so that it can be replaced by other sizes can be replaced and easily removed when not required.

A much broader application of the invention Device appears especially given when finally the mixing nozzle to the Attachment of profile nozzles is prepared, which overlap the mixing nozzle like a funnel. In this way, the device can be quickly and conveniently used for putty work Switch to filling work, joint sealing or the like. Again, it's from Importance that the connections between the individual parts are simple and against Soiling are insensitive and, in the end, the parts are individually good and comfortable get cleaned up.

The invention is illustrated by way of example in the drawing.

1 shows the device according to the invention in a diagrammatic view Depiction; Fig. 2 shows the same device, partially broken open and with a differently formed mixing nozzle-in open representation; 3 shows the front area the device according to the invention with the mixing nozzle in longitudinal section; Fig. 4 den lower part of the mixing nozzle in top view; 5 shows a section along the line V - V of FIG. 4 and FIGS. 6 to 8 different embodiments for displacement parts in side view and partly in section.

As can be seen from FIGS. 1 and 2, the device 1 consists of a storage space 2, which is used to hold bag-like and compressible storage containers 3.4 is prepared. The storage space 2 has a square shape in cross section and the containers 3, 4 are largely adapted to this shape. The front end 5 of the Storage room 2 is completed with a wall 6, which is ever designed so that after a lower slot gap 7 remains free in the outlet parts 8.9 of the Intervene storage containers 3.4. As shown in FIG. 1, it is on that front end 5 of the storage space 2 is a one-piece nozzle 10 attached, which with their end flanges 11 overlap the front marginal edges 12 of the storage space 2. Seals, not shown, are between the end flanges 11 and the marginal edges 12 intended. The nozzle 10 is on the storage space 2 by edges 13 on the sides this space 2 provided tension hook 14 held. This nozzle 10 can, as FIG. 2 shows, also be attached to the storage space 2 as a hinged structure be. For this purpose are on the upper and lower edge 12 of the storage space 2 flaps which can be connected to one another via latches 14 a or similar closures 15,16 hinged, which overlap with their side walls 17,18 in a sealing manner. aside from that is the upper flap 15 for dividing the room with an intermediate wall 19 (cf. in particular Fig. 3) equipped so that together with the flap 16 there is a mixing zone 20, which ends in a nozzle opening 21. In the mixing zone 20 are from top to bottom and pins 22, 23 projecting upwards from the bottom and engaging in a comb-like manner, as again shown in FIG. 3. The pins 22,23 sit on plates 24,25, the Groove-strip guides 26, 27 (see FIG. 5) can be inserted. The pushing in is easily vorllziehbar, since the nozzle 10 seen from above is a tapering towards the front has a conical shape, as FIG. 4 shows particularly well. This mixing zone 20 is naturally provided in the same arrangement in the one-piece nozzle 10, in which the plates 24, 25 can be exchanged just as easily with the nozzle 10 removed permit.

FIG. 1 also shows a spatula 28 which at 29 is releasably attached to the upper part 30 of the nozzle 10. It is also marked with a dashed line Lines 31 at the nozzle 10 indicated a mouthpiece-like design which makes it possible Profile nozzles to be placed tightly on the nozzle 10, which for special work, such as Filling in drill holes, etc., are advantageously suitable.

The storage space 2 is indicated schematically in FIGS. 6, 7 and 8, which in turn contains the containers3,4. According to Fig. 6 is in side slots 32 a shaft or roller 33 is mounted, which has a radial slot 34. In The ends 35,36 of the containers 3,4 are inserted into this radial slot 34, so that when the roller 33 is rotated with the aid of the handle 37 in the direction of the arrow 38 need to wind up the containers 3, 4, as indicated by dashed lines 39 is indicated. The contents of the containers are 3.4 forward in the direction the nozzle 10 pressed on.

In Fig. 7 again slots 32 can be seen, but there are In addition, toothed strips 40 are available, on which a toothed shaft 41 comes. the Shaft 41 carries a squeegee roller 42, which when the handle 37 is rotated in the direction the arrow 38 presses the containers 3, 4 against the wall 43 of the storage space a, whereby the contents of the containers 3, 4 are pushed forward towards the nozzle opening 21 will.

Finally, FIG. 8 has a displacement part instead of a squeeze roller 42 recognize in the form of a wedge 44. This wedge 44 presses the containers 3; 4 again against the wall 43, but is shown in Fig. 8 as in Fig. 7 between Wedge 44 or 42 and container 3 a spring band 45 is provided. To move the Wedge 44 in the direction of arrow 46 can be spindles, hydraulic or pneumatic Working cylinders or toothed ratchets are used, such as those shown in FIGS. 1 and 2 and denoted by the reference numeral 47, this toothed ratchet 47 is like a revolver grip executed so that handling with it the device 1 appears particularly favorable.

To advance the wedge 44 it is only necessary to push the lever 48 into the handle 49, @by moving the wedge 44 advances by one tooth of the rack 50 at a time.

The toothed ratchet 47 is attached to a flap S1, which is at 52 is hinged to the storage space 2. The flap 51 is not only used as an abutment for the ratchet 47, but si @ also enables the containers to be exchanged 3.4. As already pointed out, the wedge 44 can also be shaped like a inflatable bellows to be replaced;
