Description

Device for producing ready-to-use fillers by mixing a binder and a hardener component

description

The present invention relates to a device for producing ready-to-use filling compounds by mixing a binder and a hardener component according to the preamble of claim 1.

Apparatus and devices for mixing at least two components are used, for example, in the production of fillers, wherein a hardener component with a 1 ... 2% content of a binder component is mixed to produce a curable filler. The mixing device has for the supply of the respective components inlet openings, via which the components are added into the mixing chamber of a mixing device. The components are stored in upstream receptacles, such as can-shaped containers or cartridges, the mixing device being part of a means for providing putties.

State of the art

Such a device for producing a ready-to-use filling compound for the filling of surfaces, which relate for example to vehicle bodies, is known from DE 203 07 518 U l. The device has two reservoirs arranged at a base station, one of which is filled with a binder component, namely a putty component, and the other with a hardener component. By means of a metering device, the two components are each fed via a supply channel continuously to a mixing chamber in which the components come into contact with each other. The mixing chamber is formed from a tube section of a flexible tube, on the outside of which press rollers engage, which compress the tube section and simultaneously drive around a longitudinal axis. Due to the friction occurring and the adhesion of the components to the inner wall of the tube, the components are mixed together. After the mix has passed through the tube section, it arrives at a Hose provided outlet, where it exits continuously from the hose. The tube wall is made of an airtight plastic, so that the air surrounding the tube during the mixing process does not get into the mix and can be trapped in this in the form of pores or voids.

From DE 20 2005 005 833 Ul a device system for mixing binder component and a hardener component, to a pasty mix for producing a ready-to-use filler for filling surfaces of, for example, vehicle bodies with a support plate arranged in a device component is known Inlet opening for the supply of the binder component from a reservoir arranged on the support plate and with at least one further inlet opening for the supply of the hardener component from a reservoir arranged on the support plate and connected to the inlet openings via feed channels in the support plate outlet openings and a functionally with The support plate connectable mixing device with a number of outlet openings corresponding number of corresponding to the outlet openings of the mixing device, which is a hollow cylinder Statortei l having a discharge opening formed in its wall for the mix and a concentrically arranged in this and rotatable about a longitudinal axis rotor part with an annular gap formed between the stator and the rotor part mixing chamber, wherein a plurality of integrally formed on the stator first mixing teeth radially inwardly and a plurality of Rotor part formed second mixing teeth extend radially outwardly into the mixing chamber in order to move by means of a rotary movement of the rotor part in the stator, the mixing teeth against each other to create a mixing of the components, wherein the stator at least one connected to the mixing chamber inlet opening for the hardener component and wherein the first mixing teeth are arranged on at least one first mixing tooth plane and the second mixing teeth on at least one second mixing tooth plane, wherein the mixing tooth planes are staggered axially in the direction of the longitudinal axis, so that the second mixing teeth of the rotor part in the radially circulate respective spaces of the first mixing teeth of the stator, wherein a plurality of mixing teeth planes are provided on the rotor part and on the stator.

By this device, the mixing components are mixed together so that the mix cures reliably. In the first place, this is achieved by having two storage containers and by connecting these storage containers to the mixing chamber via separate feed channels. By means of a metering device, the mix can be continuously conveyed through the mixing chamber through a discharge opening arranged on the stator part.

EP 1 900 443 A2 describes a device system for producing a ready-to-use filler compound by mixing a binder and a hardener component. This device system for mixing at least two components, in particular a binder component A and a hardener component B, into a pasty or liquid mixture for producing a ready-to-use filler for filling surfaces, for example vehicle bodies, comprises a support plate with an inlet opening for the supply of the binder component A from a storage container arranged on the support plate and with at least one further inlet opening for the supply of the hardener component B from a reservoir arranged on the support plate and outlet openings connected to the inlet openings via supply channels in the support plate, and a Functionally connectable to the support plate mixing device with a number of outlet openings in the support plate corresponding number of corresponding with the outlet openings of the mixing device, the h ohlzylinderartigen stator having a trained in its wall discharge opening for the mix and a concentrically arranged in this rotatable about a longitudinal axis rotor part with an annular gap formed between the stator and the rotor part mixing chamber, wherein a plurality of integrally formed on the stator first mixing teeth radially inwardly and a plurality of Rotor part integrally formed second mixing teeth extend radially outwardly into the mixing chamber in order, by means of a rotational movement of the rotor part in the stator part of the mixing teeth move against each other to create a mixing of the components A and B, wherein the stator part at least one, preferably two connected to the mixing chamber inlet openings for the hardener component B and wherein the first mixing teeth on at least a first mixing tooth plane and the second mixing teeth on at least a second mixing tooth plane are arranged, wherein the mixing tooth planes are staggered axially in the direction of the longitudinal axis to each other, so that the second mixing teeth of the rotor part in the respective spaces of the first mixing teeth of the stator radially rotate, with several mixing teeth planes provided on the rotor part and / or on the stator are, wherein preferably the number of mixing teeth planes on the rotor part and the stator are the same, for the functional connection between the mixing device and the support plate of the stator at its end facing away from the inlet openings an annular support carries, the B efestigungsdurchbrechungen and the bayonet-like detachable, lockable and rotatably connected to the stator, wherein the rotation is limited by stops such that a fit of the inlet opening for the binder component A in the mixing device with the corresponding outlet opening in the support plate and at the same time a fit the inlet openings for the hardener component B is achieved in the mixing device with the corresponding outlet openings in the support plate.

This mixing device has a hollow cylinder-like stator part and a rotor part rotatably received in this concentric about a longitudinal axis and the mixing chamber between the stator and the rotor part ringpaltartig formed, wherein a plurality of molded on the stator first mixing teeth radially inwardly and a plurality of second rotor teeth integrally formed on the second mixing teeth radially extend outwardly into the mixing chamber to move by means of a rotational movement of the rotor part in the stator, the mixing teeth against each other and to provide a mixing of the two components, wherein the stator at least one, preferably has two connected to the mixing chamber inlet openings for the hardener component Before the beginning of each mixing process namely before the feed of the binder component or before the beginning of the continuous mixing process with the rotational movement of the mutually running mixing teeth of the mixer, an amount of 0.1 grams to 0.5 grams, preferably 0.2 grams pasty or liquid hardener component injected into the mixing chamber, whereupon the feed of the binder component and the inflow of the hardener component takes place.

And this injection of a minimum amount of hardener component is triggered and monitored by the controller. By injecting or injecting a small amount of pasty or liquid hardener component before or at the beginning of each continuous mixing process in the mixing chamber of the device faulty mixing results are to be avoided, because without this pre-injection always leads to faulty mixing results. This is because the mixing ratio is up to 2% to 98% of binder component and hardener component. The initial amount, which is about 1 cm ³ , then contains either no hardener or so much reduced amount of hardener that it can partially come to deficient curing. A useful cure result is therefore achieved with a benzoyl peroxide content (50% paste) between 0.8% to 5%. If this proportion is not met in over- or under-dosage, then quality problems arise in the mix. The underdosing leads to insufficient final hardness. The overdose leads to an undesirable enrichment of the binder component (putty) with plasticizer, which is about 50% contained in the hardener paste. If these guideline values are not adhered to when curing the final product, then there will be incorrect final results during painting.

However, this advance of the injection of a small amount of hardener component before the beginning of the actual feed of binder component and hardener component for the mixing process is not sufficient to a homogeneous mixing of at least two components for producing a ready-to-use fully curable filler without air inclusions to reach. This is due to the fact that the hardener component a relatively long way to the entrance to the mixing device must cover because the distance between the outlet opening and the device plate or support plate of the device and the inlet opening of the mixing chamber of the mixing device is relatively large, so that trapped in the mass of the hardener component and entrained air bubbles are transported into the mixing chamber and mixing the hardener component with the binder component are not completely eliminated by the rotational movement of the mutually running mixing teeth of the mixing device.

The DE G 93 12 543.7 is an industrial cartridge to remove from this auszuschressende masses. This industrial cartridge consists of a hull of sheet metal, wherein in an open end of the hull a axially displaceable by a pressing element Auspressboden made of sheet metal can be inserted, wherein the other end of the hull is closed by an outlet opening having a cover made of sheet metal. The outlet opening can be closed by a closing element with respect to the mass to be pressed out. This closing element is designed as sealing foil which is tightly sealed onto an inner surface of the lid and which extends radially outwardly as far as the body, the pressing bottom simultaneously undertaking the sealing of the open end of the body of the industrial cartridge. Through the sealing film, the outlet opening of the lid is hermetically sealed against the mass contained in the cartridge. In order to protect the mass from undesired change until it is used, the sealing foil acts as a closing element for the outlet opening of the cartridge. In the condition thus produced, the industrial cartridge is delivered to the end user. The end user places the cartridge in a manually or pneumatically operated dispenser, the outlet opening being connected to a dispensing line, while an outer surface of the dispensing floor is brought into contact with a dispenser of the dispensing device as a pressing element. To press the mass of the presser is moved in the direction of the cartridge bottom, wherein the mass is pressed against the sealing film in the region of the outlet opening, with the result that the sealing film in the region of the outlet opening is torn, torn or destroyed, so that the mass through the Outlet opening is squeezed out. The prerequisite for this is that a sealing film is used, which is designed so that it is destroyed by the pressure of the pressed mass to release the outlet opening for the escape of the mass. Such sealing films must have a very low thickness and consist of a material that can be destroyed by pressure under the action of the pressurized mass. Films that are made of tear-resistant plastic are in no way suitable because they have a relatively large elasticity and deform only under pressure but not rupture. In addition, such, the outlet openings of salaries for the individual components for the production of putties occlusive films under pressure by the pressurized mass during the Auspressvorganges in the edge region of the outlet opening is only partially torn open with the result that for the exit of the mass only a small portion of the outlet opening is released and thus the respectively desired and also required amount for the preparation of the filler is not provided. In addition, uncontrolled tearing or tearing of the film in the region of the outlet opening takes place during the pressing process, which often results in the film tearing in the edge area of the outlet opening or elsewhere, so that the outlet of the mass also takes place in an uncontrolled manner.

The drive of the rotor part of the mixing device is designed as an electric motor arranged in a housing. The arrangement of the mixing device is such that the mixing device is held between the device plate and the housing for driving the mixing device and fixed so that the mixing device is replaceable, wherein for the replacement of the mixing device, the distance between the device plate and the housing for the drive is changeable.

The mixing device is inserted between the device plate and the drive so that in operation, the drive shaft of the drive with the red of the mixing device is engaged, wherein the entry quantities for the binder component A and the hardener component B with the outlet openings in the device plate for the binder component A and the hardener component B correspond.

For the drive of the piston rods they are formed on their base plate facing areas as racks or provided with a perforation, which are in operative connection with the manual drive.

This manual drive for the drive and the advance of the piston rods consists of an actuating lever which is held with its angled end in a U-shaped, arranged on the base plate in its end facing away from the mixing device bearing-like housing and with the end of the angled portion with a transversely to the longitudinal direction of the piston rods extending in the bearing-like housing rotatably mounted drive shaft is connected such that upon pivotal movement of the actuating lever, the drive shaft is rotated, which carries two gears, which in a pivoting of the actuating lever and at the same time causing the rotation Drive shaft for a predetermined feed of the piston rods engage in the teeth of the racks of the piston rods, wherein the actuating lever with its free end facing the drive shaft end of its angled lever portion is in operative connection with a spring and is provided with a two-armed bell crank with the two lever arms formed pawl which is pivotally mounted on the actuating lever and the drive shaft facing lever arm engages with its pointed end auslaufendem in a arranged on the drive shaft gear with asymmetrical tooth flanks.

About the operating lever is simultaneously the on and

Turning off the drive for the mixing device, in which the switch for switching on and off is arranged at the free end of the tubular actuating lever, the interior of which receives the electrical supply lines from the drive to the switch.

By means of this structural design, the supply of the

Binder component A and the hardener component B from the can-shaped container and from the cartridge-shaped container to the mixing device by hand by means of the operating lever made insofar as the drive shaft is rotated by depressing the actuating lever, wherein at the same time the gears are rotated with the result that these move through the engagement in the racks of the piston rods in piston rod longitudinal direction, wherein the piston rod feed located in the interiors of the can-shaped container for the binder component A and the cartridge-shaped container for the hardener component B piston plates in predetermined amounts binder - Press component and hardener component out of the containers into the mixing device. Each of the mixing device supplied amounts of components are specified, the length of the respective stroke of the piston rods on the locking blade adjustment is controllable.

The invention further includes an embodiment of the device which is designed

a) that the supply of the binder component A and the hardener component B by means of control means to the mixing chamber of Mixing device is such that a small amount of hardener component B is supplied by expansion of the micro-air bubbles as a pre-injection compared to the supply of the binder component A to the mixing chamber, wherein the device for effective expansion of the micro-air bubbles one-half or three-quarter filled with hardener component B cartridge-like container, wherein the outlet opening in the device plate for the exit of the hardener component B at a distance from the inlet opening of the mixing chamber preferably 1 mm for a path length of 1 mm for the flow of Hardener component B is disposed in the mixing chamber, wherein the supply channel for the hardener component in the device plate in a lying adjacent to the outlet opening in the device plate section has a diameter of preferably 1.5 mm or 1.6 mm, and wherein before the beginning of the continuous mixing process by means of the expansion n the micro-air bubbles, an amount of 1.2 grams to 5 grams, preferably 0.2 grams of hardener component B is injected or injected,

and or

b) that the supply channel for, compared to the viscosity of the binder component A having a lower viscosity hardener component B has a diameter of 1.5 mm to 1.6 mm, wherein the mixing device on the device plate in the region of the outlet openings for the two components A and B is arranged such that the outlet opening for the hardener component B in the device plate at the inlet opening or inlet hole for the hardener component B of the mixing chamber and is congruent with this, wherein the distance of the outlet opening to the inlet opening of Mixing chamber of the wall thickness of the mixing chamber wall of preferably 1 mm, so that the path length for the flow of the hardener component B from the outlet opening in the device plate in the mixing chamber corresponds to the wall thickness of the chamber wall.

Thereafter, there is a first technical solution is that due to the structural design of the device, the expansion of the micro-air particles or micro-air bubbles in the mass of the hardener component B is utilized, the expansion only works effectively when the cartridge-like container for the hardener component B is about half or quarter filled, because the lower the cartridge-like container is filled, the lower the pressure of the micro-air inclusions in the mass of the hardener component B. With very low filling but the pressure is not enough to achieve a useful pre-injection. For this reason, it is necessary that the filling of the cartridge-like container is such that sufficient pressure is available that allows the mass to be compressed, with the result that upon release of the pressure on the micro-air pockets, it will collapse and thus the mass can not expand, so that for pre-injection the required amount of hardener component B can flow into the mixing chamber of the mixing device.

Therefore, the invention provides that the exit of the hardener component B is laid so far that the hardener component only has to travel a little way, so almost only to the material thickness of the mixing chamber of the mixing device of 1 mm, as effectively as pre-injection In particular, the binder component A is significantly more viscous in viscosity than the viscosity of the hardener component B. It is therefore necessary for the mixing device to remain on the device until a new mixture is made.

Surprisingly, it has been shown that by pursuing the

Outlet opening for the hardener component B on the cartridge-like container or on the device plate up to the inlet opening for the hardener component B of the mixing device into the mixing chamber of the mixing device irregularities in the mixing of the two components A and B and in the preparation of the filler after completion of the mixing process as well as in the later hardened putty after their processing will be mixed.

The micro-air bubbles present in the hardener component B, which is preferably a benzoyl peroxide paste or a cyclohexanone peroxide paste, ie the air bubbles, are used here to achieve a very small amount of hardener component B for the pre-injection in the mixing of the binder component A, which is a polyester composition, with the benzoyl peroxide paste of the curing agent Component B used. In the preparation of the benzoyl peroxide paste from Bezolychlorid in a water bath for cooling is cooled with ice. If the water temperature rises during the reaction, the more ice melts. The benzoyl peroxide has crystalline structure. Later, a reaction with a plasticizer takes place. In this case, small amounts of air are included. A paste of benzoyl peroxide and plasticizer contains a very small amount of micro-air bubbles, which cause a low compressibility of the material. However, this effect is different depending on the filling level of hardener component in the cartridge-like container, with the result that in a complete filling of the cartridge-like container with the hardener component B is a high compressibility by the plurality of micro-air bubbles in the Hardener mass is achieved and this compressibility allows a flow of hardener component B to the mixing device, especially since it is sufficient for a completely filled cartridge-like container with hardener component that a Nachdrück effect arises sufficient to already a small amount of about 0, To press 1% of hardener component B in the mixing chamber of the mixing device, so that at the beginning of the tapping already passes a lot of hardener component B for pre-injection into the mixing chamber. The amount of hardener component B injected by the expansion of the micro-air bubbles into the mixing chamber of the mixing device is 0.1 gram to 5.0 grams, more preferably 0.2 gram.

This flow of injection of a small amount of hardener component before the beginning of the actual feed of binder component and hardener component for the mixing process is no lead to achieve a proportional application of the binder component and the hardener component, because the hardener Component must not be more than 4%, because otherwise unacceptable reactions occur and u. a. Also, a peroxide bleaching action of the colorant pigments contained in the hardener component may occur.

A second technical solution also with the first technical

Solution can be combined, is that the flow channel for the hardener component B in the device plate has a diameter of 1.5 to 1.6 mm, so that the way the hardener mass has to cover, just like that is large, as the wall thickness of the mixing device, male 1 mm. Due to the low viscosity of the hardener component B, mixing with the supplied binder component B in the mixing zone thus occurs immediately, resulting in a slight pre-injection, or pre-injection is unnecessary. The pre-injection may thus be wholly or only partially necessary. By shortening the path from the outlet opening in the device block to the mixing chamber of the mixing device Wegzeit is saved until the binder component A strikes the hardener component B, then with the help of the rotational movement of the rotor of the mixing device and the mixing teeth with each other mixed. The combination of the hardener component with the low viscosity and the resulting thin liquid plus rotational movement of the rotor of the mixing device leads to the result of a mixing of the two components A and B from the beginning, as already at the meeting of the two components A and B, so that the first part of the binder component A, which emerges from the outlet opening of the device plate, already contains the necessary amount of hardener component B of about 2%, whereby a uniform time until gelation, namely 2 to 3 minutes is reached.

Particularly advantageous is the arrangement of a check valve in the supply channel in the device plate for the supply of the hardener component B to the mixing device, because thereby a reflux of the hardener component B after cancellation of the pressing pressure on the hardener mass in the supply channel for the hardener component B in the Device plate is prevented. It is prevented by this technical embodiment, any reflux, so that no malfunction can occur.

Furthermore, the invention includes a can-shaped container for the binder component A with a disposed on the inner wall surface of the bottom plate and the outlet opening of the can-shaped container occlusive film, wherein in the region of the outlet opening of the can-shaped container a functional on the film or a film section during the Auspressvorgang the binder component A from the can-shaped container acting knife-like or saw teeth having cutting device arranged in two cross-like Saw blade shaped moldings with the film section in the region of the outlet opening facing saw teeth for cutting and opening the film or the film section for the purpose of releasing the outlet opening of the can-shaped container for the exit of the binder component A is arranged, wherein the cutting device in the region of the outlet opening of the can-shaped container or is arranged in the region of the inlet opening for the binder component A of the mixing device.

According to a further embodiment, the cutting device for cutting and opening the film or a film section in the region of the outlet opening of the can-shaped container in the outer wall region of the bottom plate of the can-shaped container is arranged such that during or after placement of the can-shaped container, the device plate in the region of the inlet opening for the binder component A during the action of pressure by the mass of the binder component A during the first extrusion process, the teeth of the cutting device the foil section closing off the outlet opening by notches preferably centrally to the formation of bending tab-like foil sections releasing an opening for the passage of the mass of binder Component A are tearing.

Thus, the can-shaped container is formed in such a way that the bottom side by means of an outlet opening having a bottom plate formed formed can-shaped container for the binder component A with a arranged on the inner wall surface of the bottom plate and the outlet opening of the can-shaped container occlusive film is provided in the region of the outlet opening of the can-shaped container, a cutting device operatively acting on the film or a film section in the region of the outlet opening during the Auspressvorgang the binder component A from the can-shaped container knife-like or saw teeth having cutting and opening the film or a film section in order to release the outlet opening of the can be arranged can-shaped container for the exit of the binder components A, wherein the cutting device of two cross-shaped saw blade-like Formkörp with the Foil section in the region of the outlet opening facing saw teeth in the region of the outlet opening of the can-shaped container or in the region of the inlet opening for the binder component A of the mixing device is arranged, wherein the arrangement of the cutting device to the film is such that during the pressing process for the binder component A through Pressing the film pressed against the cutting device and is opened by this.

The cutting device is on the one hand an integral part of the can-shaped container on the other hand, the cutting device is an integral part of the device plate, which is connected to the mixing device, which can be removed after use of the device and replaced with a new, unused mixing device.

Thus, the can-shaped container has a bottom plate with a closed by a smooth or fluted plastic film for transport outlet and a cooperating with the container cutting device for opening the film for use, the integrated part of the can-shaped container or integrated part of the device plate of the device.

With the arrangement of the knife-like cutting device, in particular in the form of, in particular cross-like, saw blade-like moldings, in the region of the outlet opening of the can-shaped container opening of the film section, which closes the outlet opening, achieved in that the incised film, the outlet opening for the exit of the Binder component A releases, in which the individual foil sections produced by the cutting of the film are laterally pushed away by means of the pressed-mass. The knife-like cutting device, with its sharp-edged cutting edges or sawtooth-shaped cutting edges, abuts against the outer wall surface of the film section located in the region of the outlet opening. The film section is acted upon by the pressurized mass, with simultaneous cutting of the film section, so that the film section is opened.

The task of the cutting device is thus to prepare the opening of the film in the region of the container outlet opening so that by the Containers pushed out mass of film completely enthralled and released to the exit of the earth.

Another advantage is that all types of slides can be cut open. This avoids stretching of the film, which makes incision difficult or impossible.

By the cross-shaped incision of the film by means of the cutting device four circular cutout film sections (sectors) are obtained, which can adhere with their arcuate sections on the peripheral edge of the outlet opening on the bottom plate of the can-shaped container, but are laterally folded away by the mass pressed out of the container in that the outlet opening is almost completely released for the exit of the mass.

The cutting and shaping device for cutting and opening the film or film section is arranged in the region of the outlet opening of the can-shaped container in the outer wall region of the bottom plate of the can-shaped container such that during or after placing the can-shaped container on the device plate with the mixing device in the region of the inlet opening for the binder component A when pressure is applied by the mass of the binder component A during the first extrusion process, the teeth of the cutting device the foil section closing off the outlet opening by notches preferably centrally to the formation of bending tab-like foil sections releasing an opening for the passage of the mass of the binder Component A are tearing.

The cutting device is arranged in the attached to the device plate or attached to the device plate can-shaped container in the region corresponding to the outlet opening of the can-shaped container inlet opening of the device plate that provided on the device plate cutting device abuts the film in the region of the outlet opening of the can-shaped container, wherein the sheet section lying in the region of the outlet opening can be pressed against the cutting device by means of the binder component A pressed against the outlet opening of the can-shaped container, and by means of cuts for releasing the Outflow of the binder component A from the outlet opening of the can-shaped container is destructible or breakable. The device plate is shaped so that it has the function of a stand and centering device.

To increase the stability of the can-shaped container on or on the device plate of the mixing device is provided that in the region of the outlet opening on the outer wall surface of the bottom plate of the can-shaped container, a conically tapered nozzle is formed, which is placed on the standing and centering of the mixing device can-shaped Container in the inlet opening of the through hole of the stationary and centering plate is inserted. The cutting device can then be arranged in the inlet opening of the device plate.

According to the invention, the cutting device consists of at least one knife-like shaped body with the outlet opening of the can-shaped container facing cutting or toothing.

Preferably, the cutting device consists of two cruciform interconnected knife-like or saw blade shaped moldings, each mold body having a the outlet opening of the can-shaped container associated with ground teeth.

This special embodiment of the cutting device causes a cross-like cutting of the film in the region of the outlet opening of the can-shaped container. If the cutting device has a cross-shaped arrangement of two saw blade-shaped moldings which are provided with ground perforations, the film is perforated like a cross, with the result that the film is cut or torn like a cross by the pressure exerted on the film by the pressed-out mass, whereby this priority is promoted by the perforation-like, cross-like cuts. The film, that is, lying in the region of the outlet opening of the can-shaped container film section is thereby cut or torn so that four individual arise approximately triangular film sections, which are laterally pushed away by the mass expressed from the can-shaped container, so that the Outlet opening for the outflow of the mass is released. A further embodiment of the cutting device is that all the teeth of each saw blade-like shaped body have the same height.

Furthermore, each serrated shaped body of the cutting device on a row of teeth, wherein each second tooth has a greater height relative to the other teeth. With this embodiment, a pre-tearing of the film is achieved, which then follows the further tearing of the film.

This pre-tearing of the film is also achieved by an embodiment of the cutting device, in which each shaped body has a row of teeth in which the respective outer teeth have a greater height than the other teeth. There is also the possibility in the central region of the cutting device with the cross-shaped saw blades to provide teeth with a greater height relative to the height of the other teeth, especially as in this embodiment, a pre-or tearing of the film is achieved.

An embodiment of the cutting device, in which the row of teeth of each shaped body has an arcuate profile, provides the advantage that when inserting the cutting process, first the middle region of the film is cut or torn and then the edge regions of the film are at a further pressure on the film Cut or torn foil.

The same effect is also achieved in an embodiment in which each molding has a row of teeth of two outwardly conically extending to the center of the molding body extending portions of rows of teeth, wherein the end portions of the two rows of teeth pass into ground knife-like sections.

A further embodiment provides that each shaped body consists of two rows of teeth each having at least two teeth, which extend outwardly conically to the center of the shaped body, wherein the outer end region of the two rows of teeth merge into spike-like sections. The teeth of each row of teeth of the moldings of the cutting device are ground sharp enough to achieve a high cutting force on the film.

With the inventively designed device, a mixing device is provided, which has a compact construction, which is easy to handle, which is easy to transport, so that a change of location from one workstation to another workstation can be made at any time. The device allows accurate metering of the two, the mixing device supplied components, wherein a dosage of the components on the number of operating lever-Hube by means of the specially designed manual drive can be made.

Furthermore, the design of the device allows the mixing of at least two components, in particular of a binder component A with a hardener component B to a pasty mix for producing a ready-to-use, fully hardenable filler for the filling of surfaces of vehicle bodies, in particular by shortening the Way of the hardener component B to the binder component A, to achieve a uniform time to gelation of the two components of 2 to 3 minutes.

Preferred embodiment of the invention

The inventively designed device 100 for mixing at least two components, in particular a binder component A and a hardener component B to a pasty mixing device for producing a ready-made filler consists according to FIG. 1 to 4 and 7 to 13 from an approximately rectangular base plate 10th on the one end a perpendicular plate-shaped device plate 30 is arranged on its one plate side 15 a two inlet openings 31, 32 for the supply of the binder component A from a can-shaped container 90 and the hardener component B from a cartridge-shaped container 91 and on the another plate side 30b has two outlet openings 31a, 32a, to which a mixing device 1 is connected (FIGS. 14 and 15).

The inlet openings 31, 32 are connected to the outlet openings 31 a, 32 a via channels in the interior of the device plate 30.

The mixing device 1 is detachably and replaceably arranged on the plate side 30b facing away from the outlet openings 31a, 32a of the device plate 30 (FIGS. 2, 3, 4, 10 and 11).

Furthermore, a trough-shaped holder 33 for the can-shaped container 90 with the binder component 1 and for the cartridge-shaped container 91 with the hardener component B are provided on the base plate 10 in front of the device plate 30, whereby differently shaped holders can be used (Figures 1 and 2).

Both the can-shaped container 90 and the cartridge-shaped container 91 preferably have a cylindrical Behälterköper with a circular cross section.

In order to press out of the can-shaped container 90, the binder component A and the cartridge-shaped container 91, the hardener component B to supply the two components A and B of the mixing device 1, is parallel to the base plate 10, a longitudinally displaceable piston rod 40 with a arranged at one end circular piston plate 41 with an inner diameter of the can-shaped container 90 corresponding outer diameter arranged (Fig. 1, 2, 3, 10, 11, 12 and 13).

For pressing out the hardener component B from the cartridge-shaped container 91, a second, longitudinally displaceable piston rod 42 arranged parallel to the base plate 10 is provided with a circular piston plate 43 arranged at one end, whose outer diameter corresponds to the inner diameter of the cartridge-shaped container 91. If the two containers 90, 91 do not have a cylindrical container body with a circular inner diameter, but an inner diameter with a different geometric shape, then the piston plate 41 has the geometric shape of the container.

The actuation of the piston rods 40, 42 via a manual drive 50, via which the respective and required 3 stroke length of the piston rods 40, 42 for the supply of the respectively required amounts of components A and B from the containers 90, 91 in the mixing device 1, is controlled to achieve a useful curing result of the prepared putty (Figures 1, 2, 3, 4 and 8). For the drive of the two piston rods 40, 42, these are formed on their base plate 10 facing areas as racks. The piston rods 40, 42 may also be provided with a perforation itself. About these racks or teeth are the piston rods 40, 42 with the manual drive 50 in operative connection (Fig. 4, 5, 6 and 9).

The manual drive 50 consists of a manually operable and pivotable operating lever 51, a drive shaft 52, two arranged on the drive shaft 52 gears 53, 54 and a locking blade 60 (Fig. 3, 4, 5, 6, 7, 8 and 9).

According to Fig. 3 and 4, the manual drive 50 for the drive and the feed and for retrieving the two piston rods 40, 42 an actuating lever 51, with a slightly angled shorter lever portion 51a formed with its end 51b in a U-shaped bearing-like Housing 55 is held on the base plate 10 of the device 100th is arranged, in the end region of the base plate 10, which is facing away from the mixing device 1 (Figures 3 and 4).

The operating lever 51 is connected to the end 51b of its angled portion 51 with a transversely to the longitudinal direction of the piston rods (40, 42) extending in the bearing-like housing 55 rotatably mounted drive shaft 52 connected such that upon pivotal movement of the actuating lever 51, the drive shaft 52 is rotated becomes (Figures 5, 6, 7 and 8). This drive shaft 52 carries two gears 56, 57 which engage in the teeth of the racks or in the teeth of the two piston rods 40, 42. If the operating lever 51 is pivoted in the direction of arrow X in Fig. 3 in the position shown in FIGS. 4 and 7 by hand, then the drive shaft 52 is rotated, with the result that the two piston rods 40, 42 in the direction of the mixing device 1 are moved, at the same time an amount of components A and B is pushed out of the containers 90, 91 and the mixing device 1 is supplied. Each of the mixing device 1 supplied amounts of components A and B each depend on the length of the stroke, with which the piston rods 40, 42 are moved in the direction of the mixing device 1.

Furthermore, the operating lever 51 is connected to the free end 51b of the angled lever portion 51a in operative connection with a spring 568, as shown in Figs. 5 and 9. In addition, as shown in Figs. 5, 8 and 9, the operating lever 51 is connected to a pawl 60 which is formed as a two-armed angle lever 61 with the lever arms 62, 63 and which is rotatably disposed at 64 on the operating lever 51. The drive arm 52 facing the lever arm 63 is formed pointed at its free end 63 a expiring and engages with this end in a gear 65 with asymmetrical tooth flanks 66, which is arranged on the drive shaft 52 (Fig. 9). By a corresponding adjustment of the angle lever 61 and by a corresponding engagement of the angle lever in the teeth of the gear 65 at a predetermined angular position of the angle lever 61, the stroke length for the advance of the piston rods 40, 42 pretend. Which in turn reduces the amount of binder component A and the amount of hardener Component B is specified, which is supplied by the piston rod feed or by the piston plate feed of the mixing device 1.

The apparatus 100 further comprises the mixing device 1 with which the binder component A and the hardener component B are mixed. This mixing device 1 is arranged on the plate side 30b of the device plate 30, between this and an electromotive drive device, for driving the mixing device 1, which is arranged in a housing 70 (FIGS. 1, 2, 3, 10, 11, 12 and 13).

The mixing device 1 comprises a stationary stator part 16 and a motor-driven rotor part 19 arranged in the latter, wherein an annular gap forming the mixing chamber 14 is formed between the two cylindrical parts 16, 19 (FIGS. 16 and 17).

The mixing apparatus 1 is held and fixed between the apparatus plate 30 and the housing 70 for driving the mixing apparatus 1 so that the mixing apparatus 1 can be replaced. For this replacement, the distance between the device plate 30 and the housing 70 is changeable for the drive. This is done by pivoting an actuating lever 71 on the housing 70 (Figures 1, 2, 10, 12 and 12). If the actuating lever 71 assumes the position shown in these figures, then the mixing device 1 is coupled to the device plate 30 so that the nozzle-like inlet openings 17a, 17b for the supply of the components A and B in the outlet openings 31a, 32a of the device plate 30 engage and the connection of the rotor part 19 of the mixing device 1 is in operative connection with the drive. If, on the other hand, the operating lever 17 is pivoted from the position A into a position B according to FIG. 1, the connections created are released and the mixing device 1 can be removed from the device 100 for replacement. The means for separating may also have other structural configurations.

The holder of the mixing device 1 on the device plate 30 is detachable and designed such that a fit of the inlet opening 17a for the binder component A in the mixing device 1 with the outlet opening 31a for the binder component A in the device plate 30 and at the same time a fit of the Inlet 17b for the hardener component B in the Mixing device 1 with the outlet opening 32a for the hardener component B in the device plate 30 is achieved.

The mixing device 1 illustrated in FIGS. 15, 17 and 18 and designed as a disposable component comprises the stator part 16 and the rotor part 19. The rotor part 19 is inserted into the stator part 16 and rotatably mounted therein. At C, the drive for the rotor part 19 engages (FIG. 16). For supplying the mixed material, the stator 16 has inlet openings 17a, 17b, wherein the binder component A is fed through the inlet opening 17a and the hardener components B, through the inlet opening 17b. To illustrate the supply of the two components, respective arrows are labeled A, and B. The rotor part 19 is rotatably mounted about a longitudinal axis 20, wherein the ends of the rotor part 19 projections 22 are provided, which rotate with the rotor part 19 and extend into the inlet opening 17 a into it. Thus, an increase in the flowability of the thixotropic binder component A is effected, wherein the projections 22 are repeatedly attached to the rotor part 19 at the end.

The drive of the rotor part 19 of the mixing device 1 via a on the device plate 30nordnet drive means, which is preferably an electric motor drive whose drive shaft is formed in its free end so that a coupling with the drive port 2 of the rotor part 19 of Mixing device 1 can be done when the mixing device 1 is locked to the device plate 30.

The components A and B to be mixed are conveyed from the can-shaped container 90 for the binder component A and from the cartridge-shaped container 91 for the hardener component B of the mixing chamber 14 to a dispensing opening 21 provided on the stator part 16, behind in the direction of flow the inlet openings 17a and 17b and after the mixing chamber 14 is arranged. Disposed on the stator part 16 are a plurality of first mixing teeth 23 which extend radially inwardly into the mixing chamber 14, whereas on the rotor part 19 there are arranged second mixing teeth 24 which extend radially outwardly into the mixing chamber 14 (FIG. 17). About the discharge opening 21 of the mixing device, the prepared filler of the mixing device 1 can be removed. The putty is then discharged, for example, to a spatula 8 and can thus be transported for further processing of the putty (Figures 12 and 13).

By means of a rotational movement of the rotor part 19 in the

Stator 16 thus the mixing teeth 23, 24 are moved against each other, so that a mixing of the two components A and B is effected. If e.g. a pre-run of the hardener component B has already taken place and a part of the following binder component A has mixed with the hardener component B and the other two components A and B are pressed into the mixing chamber 14, the further supply of the hardener component Component B can be adjusted. Binder component A and hardener component B fed into the mixing chamber 14 are then mixed with one another. These two components A and B are supplied in a predetermined ratio as long as the mixing chamber 14 until the particular desired amount of mix is obtained.

The control of the supply of the two components A and B by means of the actuating lever 51 in conjunction with the manual drive 50th

As shown in FIGS. 3, 4, 10, 11, 12 and 13, two containers 35 and 36 for receiving unused and used mixing devices 1 are arranged on the device plate 30.

In order to be able to control the supply of the hardener component by means of a visual inspection, it is provided that at least the stator part 61 is formed from a transparent material, wherein the transparent material from the group of plastics comprising a polycarbonate (PC), a polymethyl methacrylate (PMMA ) and / or a styrene-acrylonitrile (SAN) or PP in Random quality, preferably transparent, is formed. It is also of particular advantage, the hardener component visible, so that the operator during the operation of the mixing device can control the supply of the hardener component seeing eye.

The rotor part 19 is advantageously made of polyoxymethylene (POM), also called polyacetal or polyformaldehyde formed. This material has better sliding properties with a polycarbonate or polypropylene (PP). After each use, the mixing device 1 is replaced with a new mixing device.

For switching on and off of the electromotive drive for the rotor part 19 of the mixing device 1, a switch 59 is disposed at the free end 51 c of the tubular actuating lever 51. The interior of the actuating lever 51 then receives the electrical lines from the electric motor drive to the switch 59 (FIG. 1).

As shown in FIGS. 2, 10, and 11, an optical signal direction 350 connected to a power source is arranged on the device 100 and is configured as a light 351 emitting a white or colored light, preferably green light. In addition, an acoustic signal device 360, which is designed as a signal horn or siren 361, is provided next to the optical signal device 350 on the device component 300. The device 300 may have both signal devices 350, 360 or only one of the two signal devices. Preferably, the optical and / or acoustic signal device 350, 360 is arranged visible on the housing 70 for driving the rotor part 19 of the mixing device 1.

Both signal devices 350, 360 are configured and so in operative connection with the on-off switch for the commissioning of the device 100 that activates the signal devices or only one of the two signal devices at a commissioning of the device for the production of filler, and for a given Time is put into operation, ie, for example, for a period of two or three minutes sounds the acoustic signal and the green signal lamp of the optical signaling device 350 lights up, so that other people in the workshop still have time to tap with the device putty and although as long as the acoustic signal sounds and / or the light of the optical signal device 350 lights. If the production process for the filler finished, so the signal devices 350, 360 are put out of service at the same time. Only when a new manufacturing process is initiated and the device 100 is turned on, the signal devices are reactivated. The period in which the Signaling devices are activated, can be adjusted individually and will depend on the amount of putty to be produced in each case.

The apparatus 100 for mixing at least two components, namely a binder component A and a hardener component B, comprises the can-shaped container 90 for the binder component A and a cartridge-like container 91 or 92 for the hardener component B (FIG 3).

The can-shaped container 90 for the binder component A has a cylindrical shape with a circular cross-section to form a peripheral edge 90a a retracted bottom plate 95 with an outlet opening 96 which may be centrally or eccentrically arranged in the bottom plate 95 (Fig. 22). , In its upper part designed to be closed only for transport, but formed open in use. On the bottom side, the can-shaped container 90 is designed to be closed by means of a bottom plate 95. The bottom plate 95 has the outlet opening 96.

For transport, the can-shaped container 90 by means of a

Cover 97 closed, which is removed for use. In the interior of the container 90, a sliding bottom 98 can be arranged above the mass M located in the can-shaped container 90 and can be pressurized for pressing the mass out of the container by means of mechanical, hydraulic or electromotive devices (FIG. 22). If the can-shaped container 90 is provided with a sliding bottom 98, then it is not necessary that piston rods 40, 42 are used with piston plates 41, 43.

On the inner wall surface 95a of the bottom plate 95, a film 300 is disposed, which closes the outlet opening 96 (FIGS. 22, 23, 24 and 25). The film 300 may extend over the entire surface of the bottom plate 95, but also close only the outlet opening 96. The diameter of the outlet opening 96 is preferably 32 mm or 42 mm.

The can-shaped container 90 is formed as a cylindrical shaped body and preferably designed for a capacity of about 3 liters, but also can-shaped containers can be used with other capacities. The can-shaped container 90 preferably has a circular cross-section, but also other cross-sectional shapes are possible. The outlet opening 96 formed in the bottom plate 94 has a circular cross-section (Figures 22 and 28), although other cross-sectional shapes are possible.

The film 300 is welded or glued to the inner wall surface 95a of the bottom plate 95 while covering the outlet opening 96, and is made of plastic or another suitable material that can be cut or split. (Figures 23 and 28).

The bottom plate 95 of the can-shaped container 90 has, in the region of the outlet opening 96 on the outer wall side, an outlet nozzle 99 with a conically extending outer wall surface 99a (FIG. 24). If the container 90 is placed on the device plate 30, then the outlet nozzle 99 is inserted into the inlet opening 31 of the device plate 30 (FIGS. 19, 20, 21, 24 and 29).

In the region of the outlet opening 96 of the can-shaped container 90, a knife-like cutting device 400 acting on the film 300 in the region of the outlet opening 96 during the pressing process of the binder component A for cutting or perforating and opening the film 300 in order to release the outlet opening is provided 96 of the can-shaped container 90 for the exit of the binder component A arranged (Fig.19, 20 and 22).

The size and dimensions of the film 300 correspond to the size and dimensions of the inner wall surface 95a of the bottom plate 95. It is also possible to arrange only one film section in the region of the outlet opening 96 in the bottom plate 95 of the can-shaped container. Such a film section is dimensioned slightly larger than the surface of the outlet opening 96 and glued in the edge region of the outlet opening on the Innwandfläche 95 a of the bottom plate 95.

The cutting device 400 is arranged in the region of the outlet opening 96 of the can-shaped container 90, so that a cutting and separating function of the film opening 301 closing the outlet opening is provided. The cutting device 400 can thus be an integral part of the can-shaped container 90 and is preferably arranged in the interior of the outlet nozzle 99 (FIG. 25). The cutting device 400 consists of at least one knife-like or saw blade-like shaped body 401 with the outlet opening 96 of the can-shaped container 90 facing knife-like cutting or saw teeth 403 (Fig. 30 and 31), wherein the cutting or saw teeth 403 at a very small distance from the Exit opening closing film portion 301 are arranged or act on this, without causing the film portion 301 is damaged. Thus, by increasing the internal pressure of the filler during the first squeezing operation, the film portion 301 curves toward the teeth of the cutter 400 and contacts the teeth of the cross of the blades of the cutter 400 such that a plurality of teeth Notch arises. The film of the film portion 301 starts tearing from the center to form four flap-shaped film portions 301a that are bent away (Figs. 27 and 29). These bent four flap-shaped film sections 301a thus release an opening, so that the relatively viscous mass of the binder component A can be passed through or flowed out in sufficient quantity or in the required quantity by the opening thus formed by the bent flap-shaped film sections 301a can. A notch with Aufreißwirkung takes place only at an internal pressure from 2 bar, because the outlet opening 96 of the can-shaped container 90 closable film must be sized so thick that they normal strength, which can occur during transport of the can-shaped container 90, endures and is not damaged without the fatness suffers. It is also possible, the outer wall surface of the outlet nozzle 99 on the bottom plate 95 of the can-shaped container in such a way that a protective cap is placed on the outlet nozzle 99 which is held on this by means of a press fit.

It is preferred to use a corrugated foil 300, eg of plastic, which is about 0.04 mm thick, although other strengths can also be used. The use of a corrugated foil 300 ensures that the corrugation allows the foil to form a bow to form, so that they can rest against the teeth of the cutting device 400.

According to FIGS. 30 and 32, the cutting device 400 consists of two serrated shaped bodies 401, 402 with sawteeth 403 connected to each other in a cruciform manner, each shaped body 401, 402 of the outlet opening 96 of the container 90 having saw teeth 403 (FIGS 22), wherein according to FIG. 19 and 20, the cutting device 400 is an integral part of the device plate 30 and is arranged in the region of the inlet opening 31 of the device plate.

All saw teeth 403 of each shaped body 401, 402 have the same

Heights (Figures 30, 31 and 39). The two shaped bodies 401, 402 are provided for cross-like nesting with slot-shaped recesses 401a and 402a, of which the slot-shaped recess 401a extends from the side 401b of the molding 401 facing away from the saw teeth 403 in the direction of the saw teeth, whereas the slot-shaped recess 402a of the molding 402 extends from the saw teeth toward the side facing away from the saw teeth 401b (Fig. 31). Both slot-shaped recesses 401a, 402a have a width which corresponds to the thickness of each shaped body 401, 402. The lengths of the two slot-shaped recesses 401a, 402a are dimensioned such that, when the two shaped bodies are inserted into one another, the lower sides 401b, 402b lie in a plane, so that a cutting device 400 with cross-shaped shaped bodies 401, 402 is obtained (FIGS. 32 and 33) ).

In the embodiment according to a further embodiment of the cutting device 400, each shaped body 401, 402 may have a row of teeth in which every other saw tooth has a greater height than the other saw teeth.

The row of teeth of each shaped body 401, 402 may also have a curved course.

In the embodiment of Figs. 34, 35 and 36, each has

Shaped body 401, 402 a row of teeth Z, ZI of conically extending to the center of the molding 401, 402 sections Ζ ',,, wherein the outer Transition end regions of the two rows of teeth Z, ZI into ground knife-like sections.

According to a further embodiment according to FIGS. 37 and 38, each shaped body 401, 402 consists of two rows of teeth each having at least two teeth, which extend conically towards the center of the shaped body 401, 402, wherein the outer end area of the two rows of teeth is formed into a spike-like or arrowhead-like shape Teeth go over.

The molded bodies 401, 402 and 401 ', 402' according to FIGS. 35, 36 and 37, 38 are designed with respect to the arrangement of the teeth such that the slot-shaped recesses 401a, 402a of the molded bodies 401, 402 according to FIG. 24 and the slot-shaped recesses 401a, 402a of the molded bodies 401 ', 402' according to FIG. 25, 26 in a cross-like mating of the respective molded parts to allow meshing of two equally formed moldings. The mold parts 401, 402 differ from the mold parts 40, 402 'in that the mold parts 401, 402 extend from approximately rectangular base plates with the saw teeth, whereas the moldings 401', 402 'have semicircular base plates.

According to FIG. 19, each shaped body 401, 402 can have rows of teeth with teeth of the same height. The molded body 401 shown in FIG. 40 has a row of teeth with teeth of the same height or length, the respective outer teeth having a greater height or length than the other teeth of the row of teeth. The latter embodiment has the advantage that upon pressing the foil section 301 located in the region of the outlet opening 96 of the bottom plate 95 of the can-shaped container 90, the foil of this section is prematurely torn or perforated by means of the long teeth. In the case of a cutting device 400 with saw-blade-like shaped bodies arranged in a crosswise arrangement, the teeth in the middle region of the saw blade cross may have a greater height than the other teeth.

All teeth of the cutting device 400 are provided with pointed ends, ground and sharp-edged. Those embodiments of the molded bodies 401, 402 or 40, 402 'are advantageous in which the teeth of each row of teeth taper conically towards the outer center of the Shaped molding extend. With this tooth region, the film section 301 to be opened is first applied and torn in the middle. 4 shows the arrangement of the cutting device 400 below the film section to be opened, which, however, can also be arranged in the region of the outlet opening 96 of the bottom plate 95. The cutting device 400 is then an integral part of the can-shaped container 90. If the film section 301 is pressed against the cutting device when the mass is pressed out of the can-shaped container 90, the film section becomes cross-like by means of the teeth of the cross-shaped moldings 401, 402, 40, 402 'perforated (Fig. 5) with the result that in a further pressure, the film in the region of the perforation 302 is torn open, as indicated in Fig. 6. The four approximately triangular sections 301a are laterally pushed away by the mass pressed out of the can-shaped container 90, so that the outlet opening 96 is exposed, for the perfect outflow of the mass.

The teeth of the moldings 401, 402, 401 'and 402' have the shape shown in FIGS. 30, 31, 23, 35, 36 and 38.

The film 300 is made of plastics such as e.g. PVC. Also metallized films or bicomponent films e.g. made of an aluminum foil and a plastic film can be used. Since the film section 301 located in the region of the outlet opening 96 in the bottom plate 95 of the can-shaped container 90 is perforated by means of the cutting device 400, pressure applied by the mass forced out of the can-shaped container 90 ensures that the film section is torn open, ie. a notch is created by the multiplicity of teeth of the cutting device 400, so that the film begins to tear from the center, resulting in flap-shaped sections 301a which are bent and release the opening for the emergence of the mass (FIGS. 27 and 29) ). Both thin films and thicker films can be used, the latter being opened in the same way as thin films by means of the cutting device 400.

In the same way as the can-shaped container 90 for the binder component A with a cutting device 400 functionally cooperate can, so the can-shaped container 91 may be formed for the hardener component B and also cooperate with the cutting device 400 formed according to the invention.
