EP0461371A1 - Device for optionally proportioning different flowable paint masses - Google Patents

Abstract

In a device for optionally proportioning different flowable paint masses, in which paint mass is released from a plurality of stock containers (3) into a collecting vessel (4), the stock containers are either pressurised gas cylinders containing paint mass or containers with elastically extensible interior sacks (28) which contain paint mass, the sack material of which has a high resilience and which are fitted with a product-dispensing valve (6). This makes it possible to stock different base paints with protection from oxygen and to release them in portions, to install the base paints in an easily exchangeable manner and to omit equipment components to which not negligible paint residues can permanently adhere. <IMAGE>

Description

The invention relates to a device for the optional dosing of different, flowable color compositions from a plurality of storage containers arranged in the manner of a battery into a collecting container.

A desired color shade can be achieved by mixing several basic colors in a certain mixing ratio. With a small number of color-containing storage containers, a variety of individual nuances can be achieved without having to carry out a large inventory.

Mixing colors for hair treatment in hairdressing salons is generally done manually. The oxidation-sensitive paints are mixed and mixed with an oxidizing agent, generally a 9 or 12% hydrogen peroxide solution.

From DE-OS 34 04 102 a device for supplying and dosing colors for the production of color mixtures of large quantities is known, in which basic colors are delivered to a collecting container via supply lines and valves. The use of supply lines is based on a high outlay for their technical implementation. The valves attached to the supply lines can also be damaged in their function by adhering paint.

This happens particularly often in the case of relatively small color masses, as are required in hairdressing salons. For use in a hairdressing salon, the preparation of mixed colors must not only be simple and precise. The base colors must also be easily exchangeable with new ones and adequately protected from atmospheric oxygen, and finally the cleaning of the device may require little effort. In a device according to DE-OS 34 04 102, it cannot be prevented that oxygen gets to the stored colors. When exchanging a base color for another, the corresponding supply line must also be cleaned laboriously.

The invention has for its object to eliminate the disadvantages described above or to create a device that can also be used in hairdressing salons, with which it is possible to store various base colors hermetically protected and to take them in portions, to install the base colors easily replaceably and on components to dispense with the device, to which non-negligible paint residues permanently adhere and thereby impair the functional reliability of the device.

The object is achieved according to claims 1 and 4. Thereafter, on the one hand, pressure gas containers containing ink mass are provided as storage containers of the device, on the other hand containers with ink mass-containing, elastically stretchable inner bag, the bag material of which has a high restoring force and which is provided with a product dispensing valve.

The use of pressurized gas containers or containers with an elastically stretchable inner bag in a device for the optional dosing of different flowable color compounds prevents oxygen from getting into the storage container.

Since such storage containers consist of complete storage and product dispensing devices, the exchange of individual containers is possible without any problems. Color residues can only adhere directly to the product delivery opening. However, the area suitable for adhesion is very small and the impairment of a freshly donated ink mass by an oxidized color mass residue is negligible, as with the commercially available pressure packs used for donating hair color. The device according to the invention can therefore be cleaned of paint mass buildup without great effort.

Further refinements of the invention are described in the subclaims.

A pressurized gas container designed as a two-chamber compressed gas pack with an inner bag has the advantage that an oxidation-sensitive ink is housed in a sealed bag. The blowing agent required for product delivery is separate from the hair color between the flexible bag and the container wall. This also ensures that the pressurized gas container can be almost completely emptied without the ink and propellant being temporarily and alternately dispensed at times at a low filling level in the pressurized gas container.

By using a compressed gas inlet valve in an outer container wall of the two-chamber compressed gas pack, which is detachably connected to the inner bag (claim 3), it is possible to simply refill a used pack by exchanging the inner bag and the product dispensing valve and to add the necessary compressed gas via the compressed gas inlet valve. The outer container wall can be reused. The waste mass and the costs of the compressed gas containers are thus reduced.

Supply lines between the storage containers and a collection container are not necessary if the product discharge valve of a compressed gas container is positioned vertically downward above the collection container during product delivery (claim 5).

By means of a product-wiping agent on the product dispensing valve of the storage container (claim 6), it is possible to scrape off ink that has already been donated but has not yet fallen off immediately after the dispensing process has ended, thereby shortening the product removal process. There is no uncontrollable dripping.

If the product stripping agent is a glow wire (claim 7), then the ink mass adhering to the glow wire after the stripping process is heated. As a result, it drips relatively quickly into the collection container.

A briefly and approximately two-dimensionally acting air flow pulse as a product stripping means (claim 8) has the advantage that the stripping process can lead to no renewed adherence of the ink mass on another component of the device according to the invention except on the collecting container. The air flow surge can be generated by means of a compressor.

With an axially actuable product dispensing valve on the storage container (claim 9), it is possible to align it downwards and to hold the product dispensing valve and the storage container during the product dispensing process by means of a pair of pliers and to press it against one another (claim 10). Product donation is thereby achieved without mechanical stress and possibly damage to the holder of the storage containers.

If a pressure gas inlet valve is placed in the bottom of the outer container wall of a pressure gas container, and if the part of the pliers which touches the bottom of the pressure gas container is equipped with a pressure gas discharge valve of a pressure gas supply (claim 11), the pressure gas container can be supplied with pressure gas during a product removal. There is no pressure drop in the container and the associated reduced mass flow and the dosing accuracy is not affected by the pressure. In addition, a factory pressure gas filling is not necessary.

By using a tilt valve as a product delivery valve on the storage container (claim 12), a compact design of the device is achieved in the direction parallel to the storage container axis.

The product mass taken from a storage container can be determined by positioning the collecting container on a balance.

The actuation of the product dispensing valve by a computer-controlled actuator (claim 14) has the advantage that individual color mixtures can be specified by the computer and removed from the storage containers via the actuator. By communicating the removed product mass from the scales to the computer (claim 15), it is possible, on the one hand, to open the product dispensing valves further or less depending on the time in order to carry out a coarse or a fine metering.

If the device is connected to a feed mechanism for storage containers (claim 16), different basic colors can be stored and supplied particularly easily. The number of storage containers can be relatively small, but the number of color shades that can be achieved is then still relatively large. A maximum service life of the device Without replacing individual storage containers, the basic colors can be stored one or more times according to their expected frequency of use and the quantities of product to be dispensed (claim 17).

By equipping the feed mechanism with a receptacle receptacle that can be linearly displaced in two horizontal directions that run at right angles to one another (claim 18), a particularly compact feed is provided.

A rotatable feed mechanism can be locked particularly precisely in predetermined angular positions if recesses are provided on the receiving plate of the feed mechanism, into which a blocking device engages immediately before the product dispensing process (claim 19). Rotatable individual plates on the receiving plate (claim 20) offer the possibility of rotating all the storage containers stored on the feed mechanism into a position of a certain radial distance from the center of the circular receiving plate and thus only a single removal position for everyone even when the receiving plate is equipped in its radial direction Provide storage containers.

The electrical connection of the computer with the drive of the feed mechanism (claim 21) makes it possible to specify the amount of product to be removed per position of the feed mechanism via the computer and to add up the amount of product removed in each case. A user of the device can thereby receive information about the supply of individual basic colors.

The user can easily exchange individual basic colors for others without paying attention to special computer programs if the storage containers are provided with codes, each of which provides information about the corresponding one Contain base color, and the computer is connected to at least one device for recognizing these codes (claim 22). The code information is processed together with control information about the position of the storage container brought up to the device for code recognition in the computer. However, the code recognition can also be used so that the user only has to inform the system of the feed mechanism concerned after the exchange of a storage container, for example by entering a position number.

In principle, it is sufficient to provide only one device for code recognition. This can be installed at any accessible location next to the container holder. After replacing a storage container for a new one with a different color, the new storage container must be detected by the code recognition device before it is inserted into the pliers. By using several devices for recognizing the code, the working speed of the device according to the invention is increased, since several storage containers can be identified simultaneously. With two such devices on both sides of the pliers and in close proximity to them (claim 23), different directions of movement of the receptacle, for example different directions of rotation of a plate, are possible with complete code monitoring.
Optical marking readers which identify bar codes (claim 24) and electrical voltage devices which detect ring-shaped conductivity codes by means of sliding contacts, work particularly reliably.

It is possible to provide at least one further container on the device which is not a compressed gas container (claim 23). This increases the area of application the device: for example, thinners or additives can be stored in such a container and dispensed from it. For use of the device for preparing hair colors, it is advantageous if a container is connected to the device which contains hydrogen peroxide (claim 24), since this oxidizing agent is used for permanent hair coloring. If two containers containing different hydrogen peroxide concentrations are connected to the device (claim 25), then the choice between 9 and 12% peroxide solution desired by the hairdresser can be met.

The arrangement of the dispensing opening of the container above the collecting container and the regulation of the dispensing opening by a computer-controlled actuator (claim 26) regulates the addition of peroxide to the ink mass in a program-dependent and thus particularly reproducible manner.

The device 1 for the optional dosing of different, flowable color compounds is provided with a feed mechanism 2, by means of which a storage container 3 is transported into a position above a collecting container 4 (FIG. 1). The storage container 3, for example a pressurized gas container 5, contains an ink 3a. Its product discharge valve 6 is oriented downwards. A lever 8, which is rotatably mounted on an axis 7, presses axially on the product discharge valve 6. The lever 8 is actuated by an actuator 9, which is connected to a computer 10 by means of an electrical line 11. Likewise, a scale 12 loaded by the collecting container 4 is connected to the computer 10 via a line 13 and a pump 14 via a line 15. The pump 14 serves hydrogen peroxide 16a to be conveyed from a container 16 through pipes 17, 18 into the collecting container 4.
In the process of selectively dosing different, flowable color materials from several storage containers, individual storage containers 3 are moved one after the other by the feed mechanism 2 into the product removal position. The product quantities to be removed in each case are predefined by the computer 10 to the actuator 9 and the product quantities removed are checked via the scale 12. After the ink has been removed, hydrogen peroxide 16a is added to the collecting container 4 after the computer has been specified.

The product dispensing valve 6 can be designed as an axially actuable valve 19 (FIG. 2) or as a toggle valve 20 (FIG. 3). In the case of an axially actuable valve 19, the lever 8 presses axially on a product delivery tube 21 (FIG. 2). For this purpose, the lever 8 has a conical opening 22 below the product delivery tube 21 and loads a ring element 23 on the product delivery tube 21 with the edge of this opening 22. Colorant 3a donated through the product delivery tube 21 can thus pass through the opening 22 into a collecting container.
In the case of a product dispensing valve 6 designed as a tilting valve 20, the product dispensing tube 21 of the storage container 3 is deflected radially by means of a lever 8 in order to remove ink mass 3a from the storage container 3 (FIG. 3).

Instead of storage containers with propellant, containers with an inserted elastically highly stretchable inner bag 24 can also be used as storage container 3 (FIG. 4). As a result of the restoring force of the inner bag 24, there is a relatively high pressure therein. The ink mass 3a stored in the inner bag 24 can thus be dispensed through the product delivery tube 21 when the axially actuable valve 19 opens. The inner bag 24 contracts during a product removal. Through a hole 25 in the Container wall 26 then flows air into the volume between inner bag 24 and container wall 26.

In the case of a two-chamber compressed gas pack 27, the inner bag 28 has the function of storing ink mass 3a and propellant gas 29 separately from one another (FIG. 5). In the case of storage containers 3 with a highly stretchable inner bag 24 (FIG. 4) as well as in two-chamber compressed gas packs 27 (FIG. 5), an oxidation-sensitive ink composition 3a is very well protected against oxygen from the air.

A storage container 3 is transported into a pair of tongs 30 for the purpose of removing ink mass (FIG. 6). The pliers 30 are closed by means of a disk 31a rotated by a rigidly fastened electric motor 31 and thereby presses on the bottom of the storage container 3 and on its product dispensing valve 6. An adapter 32 is plugged onto the product dispensing tube 21. In the forceps arm 33, which transmits the force of the length 30 to the product discharge valve 6, there is a product passage 34, on which a slotted hollow cone 35 is fastened. When the length 30 is closed, the donated ink is discharged through the hollow cone 35 and the product passage 34 into a collecting container located below. The slot 36 in the hollow cone 35 allows the storage container 3 to be transported further with the tongs 30 still almost closed.

The design of the valve actuation device as pliers 30 also allows the use of a two-chamber compressed gas pack 27 with a compressed gas inlet valve 38 inserted into the bottom of the container wall 37 (FIG. 7). Compressed air is introduced into the reservoir 3 through the compressed gas inlet valve 38 and fills a gas space 39 there. The pressure acts on a deformable inner bag 28 which forms a structural unit with the product dispensing valve 6 and which contains a color mass 3a. By an axial actuation of the product delivery tube 21 then the product delivery. A pressure drop in the reservoir 3 is avoided in that the part of the pliers 30 touching the bottom of the compressed gas container 5 is provided with a compressed gas discharge valve 40 of a compressed gas supply 41 which can be placed on the compressed gas inlet valve 38 (FIG. 8). Since there is therefore a constant internal pressure in the compressed gas container 5 during a product removal process, the ink mass dispensed per unit of time is also constant and therefore easily reproducible. The container wall 37 of the pressurized gas container 5 is releasably connected to the structural unit comprising the inner bag 28 and the product dispensing valve 6 via clips 41a and a sealing ring 41b (FIG. 7). If the inner bag 28 is empty, this unit can be replaced with a new one. The container wall 37 with the compressed gas inlet valve 38 is thus reusable.

In order to strip off the ink that has already been donated after the end of a product removal process, but still adheres to the product delivery tube 21, thereby shortening the product removal process and preventing uncontrolled dripping, a glow wire 43 (FIG. 9) can be used as the product stripping agent. The glow wire 43 connected to electrical supply lines 44 is slightly offset from the slot 36 of the hollow cone 35 (FIG. 10). Thus, the product is released without being influenced by the glow wire 43. Only when the storage container 3 is transported further does the product discharge tube 21, together with the adapter 32 attached to it, move past the slit 36 closely above the glow wire 43. In this case, any remaining ink mass hanging from the product delivery tube 21 is stripped from the glow wire 43. Adapter 32 and product delivery tube 21 are guided through the slot 36 of the hollow cone 35 when the storage container 3 is transported further. The color mass residue stuck on the filament 43 after the stripping process is heated on the filament 43.

As a result, the viscosity of the ink mass increases there and it drips into the collection container. The filament 43 can either be heated permanently or by means of a short current pulse directly before, during or directly after a stripping process.

In addition to single-slotted hollow cones 35 (FIG. 10), double-slotted hollow cones 45 can also be used on a pair of pliers (FIG. 11, FIG. 12). It is then possible to insert the adapter 32 into the hollow cone 45 while the pliers 30 are almost completely closed. The pliers 30 shown in FIGS. 11 and 12 in the open and in the closed state are provided with a spring 47 equipped with hooks 46 between the force-side end of the lower pliers arm 33 and the rotatable disk 31a of the fixedly mounted electric motor 31. This enables a particularly gentle build-up of force on the adapter 32 during the closing process.

The individual storage containers 3 are supplied by means of a feed mechanism 2 which is equipped with a rotatable receiving plate 48. The receiving plate 48 is double-bottomed (Figure 13). The upper plate disk 49 serves mainly to fix the storage container 3 in the horizontal direction. The reservoir 3 is supported with the lower plate 50. The adapters 32 lie on the edges of round product passages 34. The lower plate disk 50 is provided with cutouts 52 on the lower plate edge 51. These recesses 52 lie at the same circumferential angles as the circular storage container receptacles 53 recessed in the upper plate disk 49. Before the ink mass is removed from a storage container 3, the double-bottomed receiving plate 48 is inserted into a recess by means of a blocking device 54 formed on the lower pliers arm 33 on the pliers 30 52 clicks into place, blocked. By switching on of an electromagnet 55 rigidly connected to the non-articulated end of the lower gun arm 33, the lower gun arm 33 rotatably mounted on a further axis 56 is moved upward in the area of the blocking device 54. At the same time, the vertically installed rod 57 of the pliers 30 is pushed upwards and thus exerts a pressure on the bottom wall 58 of the storage container 3 via the upper pliers arm 33a. This pressure causes the product to be dispensed from the storage container 3. The ink mass dispensed falls through the product passage 34 of the lower plate disc 50 and a ring 60 formed by the lower pincer arm 33 into the collecting container 4.

The storage containers 3 accommodated in the feed mechanism 2 are each provided with a code 60a, which contains information about the content of the storage container 3 in question. The code 60a is scanned by a device 60 for code recognition by means of sliding contacts 60b. The sampled signal is a very low electrical voltage, the amount of which depends on the electrical conductivity of the code surface. The voltage supply for the code 60a takes place by means of a further sliding contact 60c which touches the storage container 3.

A more compact design of a round feed mechanism 2 can be achieved by two rows of storage containers 3 arranged in a circle and concentrically to one another on an annular receiving plate 61 (FIG. 14). With such a feed mechanism 2, two tongs are required, which act at different radial distances from the axis of rotation of the receiving plate above the collecting container 4. These radial distances are predetermined by the circular paths of the two rows of storage containers. In the central region 62 of the annular receiving plate 61, two further containers 16 are fixed in place, which contain hydrogen peroxide 16a in different concentrations. Both the Color mass 3a donated for hair coloring from the individual storage containers 3 and the mass of hydrogen peroxide 16a from the stationary containers 16 are measured by the scale 12 loaded by the collecting container 4.

In a further embodiment of the feed mechanism 2, the receiving plate 48 is designed as an annular receiving plate 61 with rotatable and lockable individual plates 63 mounted thereon (FIG. 15). On each individual plate 63 four storage containers 3 with color mass 3a are accommodated. The product is removed from the storage containers 3 in a position above the center of the collecting container 4. For this purpose, first the annular receiving plate 61 and then the corresponding individual plate 63 are rotated such that the desired storage container 3 is positioned above the center of the collecting container 4.
