Description

The invention relates to a canister for receiving pumpable media, in particular for receiving thixotropic and / or thickening fluids, such as thixotropic color pigment preparations, according to the preamble of claim 1, a method for withdrawing a pumpable medium, in particular a thixotropic fluid, such as a thixotropic color pigment preparation , from a canister according to the preamble of claim 15, as well as a metering device for metered dispensing of color pigment preparations according to claim 17.

Such canisters or containers are used, for example, in the dispensing of paints in so-called paint dispensers. In this a large number of different shades is reproducibly composed of a significantly smaller number of primary colors (color pigment preparations). Such paint dispensers are well known in the art and regularly comprise a housing in which various, the color pigment preparations containing canisters are housed. These canisters are connected via fluid-conducting connections with a pumping device, which in turn is fluidically connected to a metering unit. By means of such a Farbdispensers thus predetermined shades can be reproduced be mixed together, the individual components are specifically controlled by means of a computer unit in which different color combinations are stored. The medium is dispensed regularly via a dosing head of the dosing unit, which usually has a plurality of dispensing nozzles for dosing into a container containing a base, for example a white or transparent paint.

Such a color dispenser is for example from the EP 2 781 257 A1 known. The local canisters each have a canister directly associated with the conveyor, by means of which a pumpable medium received in the canister can be removed controlled by a valve device. The valve device is designed and controllable such that at least part of a quantity of pumpable medium withdrawn from the canister can be returned to the canister. The conveyor itself is formed by a arranged on the canister pump with a pump housing, wherein the designed as a multi-way valve valve device is connected to the pump housing, in particular the pump housing directly adjoins a valve housing of the multi-way valve.

In canisters of this kind, in particular in conjunction with thixotropic and / or thickening fluids or with thixotropic and / or thickening color pigment preparations, optionally in the areas facing away from the canister outlet opening or in the areas of the canister interior facing away from the pump for the accumulation of material, in particular Form of a non-pumpable state occupying and thereby not removable or abpumpbaren from the canister interior material accumulations of the medium, come, which affects the Abzieh- or Abpumpvorgang in an undesirable manner or ultimately leads to an incomplete material discharge from the canister.

In order to avoid such accumulations of material, it is already known to break the thixotropy or thickening by means of agitators aligned in the container vertical axis and rotating around the container vertical axis. However, the problem here is that, depending on the fluid, due to drying effects, adhesions to the stirrers or the stirrer can occur and thus the layer structure becomes ever larger. In the WO 00/13918 A1 For example, such agitators are shown.

Object of the present invention is therefore to provide a canister for receiving pumpable media and a method for withdrawing a pumpable medium from a canister, can be reliably avoided by means of the accumulation of material of non-pumpable medium in the canister interior and thus allows complete emptying of the canister becomes. Another object of the present invention is to provide a metering device having such canisters or to which such a method is applicable.

This object is achieved with the features of the independent claims. Advantageous embodiments thereof are the subject of the dependent claims.

According to claim 1, a canister for receiving pumpable media, in particular for receiving thixotropic and / or thickening fluids, such as thixotropic and / or thickening color pigment preparations, proposed having a canister associated withdrawal device, for example a pump, by means of a in Canister interior recorded pumpable medium from the canister is removable. According to the invention, it is provided that the canister has at least one vibration element, by means of which an accumulation of material accumulating in the canister interior and taking over a non-pumpable state and thereby not being able to be withdrawn from the canister interior pumpable medium in a pumpable and peelable by means of the trigger device state can be transferred.

With such a solution according to the invention, accumulations of material are eliminated in a functionally reliable manner, thereby ensuring that the pumpable medium located in the canister can be completely withdrawn from the canister.

Furthermore, with the vibrating element according to the invention, there is the advantage that when bubbling gas bubbles are generated, which agglomerate, then rise as larger gas bubbles and can cause an advantageous degassing of the fluid.

Under-thickened fluids are understood here in particular to be viscous and / or gelling fluids.

In principle, the at least one vibrating element could be placed at any suitable location on the canister to effect the shaking of the accumulation of material, for example also on the outside of the can itself to vibrate the canister as a whole. However, particularly preferred is an embodiment in which the at least one vibration element is arranged in the canister interior. As a result, the at least one vibrating element is arranged or used exactly where the accumulations of material form, which causes their particularly functionally reliable transfer into a pumpable state and thus removable by means of the take-off device.

Since the accumulations of material accumulate particularly frequently in the bottom area of a canister interior or in the region of an outlet opening of the canister, it is particularly advantageous, according to a particularly preferred embodiment, for the at least one vibrating element in the, with respect to the vertical axis direction, bottom-side region of the canister interior and / or in the region of an outlet opening of the canister, via which the medium flows out of the canister interior or is drawn off.

According to another particularly preferred embodiment, it is provided that the at least one vibration element is coupled to a vibration generator or the at least one vibration element has a vibration generator. The vibration generator is designed so that when it is actuated, the vibration element is set into vibratory vibrations and that the vibration element is in its non-operation in a non-vibrating rest position. The vibration generator can basically be designed in different ways. However, a vibration generator which is formed by an eccentric motor, that is to say is formed by a preferably electrically, pneumatically or hydraulically controllable motor, by means of which an eccentric weight generating an imbalance and thus vibration vibrations is driven, in particular rotationally driven, is particularly advantageous and functionally reliable. The eccentric motor is preferably received in a liquid-tight manner in a motor housing of the vibrating element.

The at least one vibrating element can, according to a particularly preferred embodiment, be supported and / or supported and / or suspended relative to the stationary canister interior space walls by means of a support and / or holding device such that they can move in the canister interior. Particularly preferred is an embodiment in which the at least one vibrating element by means of the supporting and / or holding device is mounted oscillating or resilient in the canister interior. Under a swinging or resilient storage is understood to mean any storage that makes it possible for the vibrating element to vibrate relative to the canister interior space walls. The oscillating or resilient mounting can be carried out in different ways, with an oscillating or resilient bearing caused by elastically resilient spring elements being particularly preferred.

According to a specific embodiment, the supporting and / or holding device may be formed by a plurality of, preferably spaced, support springs, by means of which the vibrating element is resiliently supported on the canister interior side, in particular with a defined prestress, and / or suspended and / or suspended. This canister interior side support, support and / or suspension is particularly preferably in the area of the canister interior side wall and / or on the canister interior bottom wall.

The vibrating element has, according to a particularly preferred specific embodiment, a vibrating plate, in particular an at least partially planar vibrating plate. Such a vibrating plate allows fourfold constructive possibilities that have an advantageous effect on the design of the solution according to the invention. Thus, the vibration generator, in particular an eccentric motor as a vibration generator, can be arranged on such a vibration plate in a particularly simple manner, for example, be accommodated in a motor housing formed there. The housing causes an advantageous foreclosure of the eccentric motor of the surrounding medium and thus ensures a reliable permanent operation of the vibrating element. Furthermore, such a vibrating plate can be arranged in the canister interior with a well-defined gap distance to the canister interior side wall and thus, in the desired manner, the canister cross-section, to the required gap distance to enable the vibration plate vibration relative to the canister interior walls, are substantially closed. Likewise, such a vibrating plate in a particularly simple manner be arranged spaced above a canister interior bottom wall and also the unhindered vibration of the vibrating element are ensured relative to the canister interior wall.

On the vibration plate itself is preferably a plurality of marginal circumferentially spaced support springs arranged by means of which a functionally reliable and reliable support, support and / or suspension of the vibrating plate in the canister interior is possible. According to a particularly preferred specific embodiment, it is proposed that the support springs are formed by a plurality of projecting from the vibrating plate and the peripheral edge portion of the vibrating plate outwardly toward Kanisterinnenraumwand superior spring legs which are supported in the mounted state of the vibrating plate on the canister interior side wall and hold the vibrating plate, preferably with a defined bias, in the defined gap distance to the canister interior sidewall. In this case, a further embodiment is particularly advantageous in which a plurality, relative to the plate plane, upwardly and downwardly projecting from the vibrating plate spring legs are provided, the broad support of the vibrating plate for a secure hold thereof or a sufficient vibration possibility of the vibrating plate relative to the allow surrounding canister interior walls. In this case, a concrete embodiment is particularly preferred in which at least one upper leg projecting from the vibrating plate and at least one lower spring leg projecting from the vibrating plate form a group of spring legs which, in relation to the side view, project in a V-shape from the vibrating plate and thus have a particular advantageous two-point support in this area allows.

Alternatively or in addition to the spring legs just described may also be provided for the resilient mounting of the vibrating plate that at the at least one support spring is arranged in the assembled state of the underside of the canister interior bottom wall facing the vibration plate, which is then also preferably supported in the region of the canister interior space bottom wall. Here too, alternatively or additionally, a functionally reliable oscillating arrangement or mounting of the vibration plate in the canister interior can be ensured. Also, a suspended solution is basically possible, in which the vibrating plate is suspended in the canister interior via, for example, arranged in the area of the canister top wall swinging hanger.

The spring legs are preferably with their free ends directly to the respective associated Kanisterinnenraumwand. Optionally, however, at least a portion of the spring legs with the free spring leg ends, preferably by means of a latching connection, be releasably fixed in accordance with assigned kanisterinnenraumwandseitigen recordings. Such releasable fixing of the free ends does not affect the vibration behavior of the vibrating plate, but ensures that it can not float in the canister interior. In order to avoid floating, it may further be provided according to an alternative or additional embodiment that the vibrating plate is weighted with a weight or with a weight element.

The vibration plate itself can, in particular to ensure that it can also be flowed through, be formed at least partially as a grid with a grid structure.

Furthermore, the vibrating plate can basically be made of any suitable material or material. Particularly preferred, in particular also with regard to the formation of the oscillating or resilient Storage by, for example, elastic support springs, the vibrating plate is at least partially made of a plastic.

In addition, the vibrating plate can in principle be arranged in any suitable and desired way in the canister interior. However, an embodiment is particularly preferred in which the vibrating plate in the canister interior is arranged inclined in the direction of an outlet opening of the canister, via which the medium flows out of the canister interior. As a result, the vibrating plate can then act as a kind of "chute" and advantageously support the removal or pumping out of the material that has been transferred back to the pumpable state.

Particularly advantageous is an embodiment in which the vibration generator is coupled to a control and / or regulating device, by means of which the vibration generator and a pump of the discharge device, in particular a pump arranged on the canister of the discharge device, substantially simultaneously and / or for an equal period of time can be controlled and actuated. This ensures that the previously solid and now again in the pumpable state transferred medium is actually withdrawn from the canister and not as material accumulation or accumulation of material in the canister remains.

The advantages resulting from the process control according to the invention are identical to the advantages mentioned above in connection with the canister, so that reference is made to avoid repetition to the statements made above.

Likewise, the advantages mentioned above also result in connection with the metering device according to the invention.

The invention will be explained in more detail with reference to a drawing.

In the Fig. 1 is shown in perspective and only by way of example as a color dispenser 1 acting metering device for dispensing here, for example, colors or color pigment preparations. Around a central dosing head unit 2 around a plurality of, with their longitudinal sides substantially adjacent to each other or with a defined gap spacing spaced apart canisters 3 are arranged semicircular, of the canisters 3 here only one, a refill opening occlusive closure lid 4 is visible and the Canister tops otherwise covered by a part of a housing wall of the Farbdispensers 1 forming cover 5 are covered. The cover plate 5 is removable, so that the canisters 3 and their maintenance openings are accessible. The canisters 3 here preferably have a wedge-shaped outer contour, wherein, as in the Fig. 1 shown schematically, optionally also different lengths or large canisters 3 can be used.

The canisters 3 are filled with different color pigment preparations, and, by appropriate control, can convey their respective color pigment paste to the dosing head (not shown) of the dosing head unit, the respective color pigment paste being introduced into a mixing vessel 6 having a base color, for example white, which is here is arranged for example on a podium-like receptacle 7 of the Farbdispensers 1.

The dosing head unit 2 together with one of these associated, the canisters 3 receiving housing unit is as shown spaced above a Contact surface of the Farbdispensers 1 and spaced above the receptacle 7 for the mixing vessel 6 is arranged.

At the dosing head unit 2, a control computer 8 is further arranged, in which different color combinations are stored and accordingly different color mixtures can be provided by means of the Farbdispensers.

In the Fig. 1 canisters 3, which are designed to be container-like or wedge-shaped containers, can in principle be constructed as described in particular in US Pat Fig. 2 is shown, wherein the canisters 3 form a more or less rectangular canister interior cross-section with bottom wall, side wall and ceiling wall.

Like this from the Fig. 2 It can be seen, at one of the Dosierkopfeinheit associated narrow side 9 of the canister 3 a extending over at least a portion of the narrow side length cylinder-piston pump 10 may be arranged, which has a pump cylinder 11 which is connected to the canister 3 and its narrow side 9 or is arranged on this, optionally also of the same material and / or is integrally connected thereto. In this pump cylinder 11, a piston, not shown here, the cylinder-piston pump 10 is slidably guided, for which purpose the piston is connected to a piston rod, also not shown here.

At the upper end of the pump cylinder 11, seen in the vertical axis direction of the canister 3, the piston rod (not shown here) interacts with a piston actuating device 14 likewise not shown here in detail, the piston actuating device 14 or its housing having a connection flange 15, which is firmly connected by means of a plurality of screw connections, not shown here, with an associated connection flange region of the upper end of the pump cylinder 11.

At one of the piston actuator 14 opposite end portion of the pump cylinder 11, a multi-way valve 22 is arranged here, to which in turn a valve actuator 24 connects. This, for example, an actuator having valve actuator 24 has a Anschraubflansch 25 which is assigned to a plurality of circumferentially around the valve housing around and spaced from each other Schraubdomen 26 such that the valve actuator 24 by means of several fastening screws, not shown here by the Anschraubflansch 25th can be screwed through into the screw 26, to connect the valve actuator 24 and its housing fixed to the valve housing.

The control of the valve actuator 24 takes place here as well as the control of the piston actuator via a control device 16, which, as shown in Fig. 2 can be seen on the canister 3 or here for example the pump cylinder 11 is arranged. The control device 16 itself is again controlled by the program controlled by the control computer 8.

Such a compactly constructed canister 3 together with its entire components can be used in a simple manner in the color dispenser 1 and be coupled there, for example, electronically or via a valve-side hose connection 27 with the Dosierkopfeinheit 2 flow connected.

The multi-way valve 22 itself is fluidly coupled via a valve-side orifice 44 with an outlet opening 46 of the canister 3, via this outlet opening 46, the medium withdrawn from the canister by means of the cylinder-piston pump 10 as a discharge device flows out or flows.

Regarding the operation of the cylinder-piston pump 10 and the multi-way valve 22 is on the EP 2 781 257 A1 in which this is described in detail and comprehensively.

As this now from the Fig. 3a it can be seen that a schematic, bottom-side longitudinal cross-section through in the Fig. 2 only exemplarily and schematically shown canister 3 (without, however, the multi-way valve 22, the cylinder-piston pump 10 and the two components associated actuating devices to show), it may in certain media, especially in the present example used, thixotropic or It is possible that in a region of the canister interior 12 remote from the outlet opening 46, a material that accumulates non-pumpable state and can not be withdrawn from the canister interior 12 is formed or accumulated in the pumpable medium received in the canister interior 12, so that only a portion of the pumpable medium according to the arrows 17 can be withdrawn from the canister 3 via the outlet opening 46.

To such, a non-pumpable state occupying and thereby not deductible from the canister interior 12 material accumulations 13 of the pumpable medium again into a pumpable and removable by means of the cylinder-piston pump 10 state is, as further Fig. 3a and the Fig. 3b can be seen in the canister interior 12, a substantially formed by a vibration plate 18 vibrating element arranged, the or its operation below also in connection with the Fig. 4a to 4c will be described in more detail.

The vibration plate 18, which here has a lattice structure, namely an exemplary honeycomb structure, is preferably made of a plastic material manufactured and has in the circumferential direction a plurality of spaced-apart, supporting springs forming spring legs 19, 20. As this in particular from the Fig. 4a and 4b it can be seen here is a plurality of, based on the mounted position, of the vibrating plate 18 upwardly and downwardly projecting and the peripheral edge portion 21 of the vibrating plate 18 outwardly toward Kanisterinnenraumwand superior, upper and lower spring legs 19, 20 provided in the assembled state of the vibration plate 18 (see Fig. 3a and 3b ) resiliently, in particular with a defined bias, supported on the canister interior side wall 23 and hold the vibrating plate 18 in a defined gap distance 28 to this canister interior side wall. This gap spacing 28, which is preferably formed completely circumferentially around the vibrating plate 18, allows the vibrating plate 18 to be movably supported and retained in the canister interior 12 relative to the stationary canister interior walls.

As this particular from the Fig. 3a and 3b it can be seen, thereby base the upper and lower spring legs 19, 20 each with their free ends 29 on the respectively associated Kanisterinnenraumwandbereich. It is understood that the spring legs 19, 20 elastically spring-back, in particular of an elastically resilient material, for example of a plastic material, are formed or elastic spring-back to the vibrating plate 18 are connected to the displaceability of the vibrating plate 18 relative to the canister interior walls allow or ensure.

How this in particular from the synopsis of Fig. 3a and 3b in conjunction with the Fig. 4a to 4c it can be seen, certain of the upper and lower spring legs 19, 20 form a spring leg group, which, based on the side view, projecting V-shaped from the vibrating plate 18 and thus form an advantageous regionally two-point support. As an alternative or in addition, at least one support spring, which is supported in the area of the canister interior space bottom wall 30, may in principle also be provided on the underside of the vibration plate 18 facing the canister interior space bottom wall 30, which is not shown here.

Like this further in particular the Fig. 3a and 3b can be removed, the vibrating plate 18 is arranged here in the direction of the outlet opening 46 inclined in the canister interior 12.

On the vibrating plate 18, an eccentric motor 31 is further supported as a vibration generator, which, in particular, the combination of Fig. 4a to 4c can be removed, in a vibration plate side motor housing 32, preferably liquid-tight, is added. The motor housing 32 itself is here formed in two parts and has a removable cover part 33, which in the removed state ( Fig. 4b ) allows the insertion of the eccentric motor 31 in a base part 35. The cover part 33 can be connected in the mounted, assembled state via a latching connection 34 fixed to the base part 35 of the motor housing 32. On the cover part 33 of the motor housing 32, a connection opening 36 is further formed, via which a line 37, in the Fig. 3a and 3b is shown only very schematically and dash-dotted lines, substantially liquid-tight (for example, via the O-ring 38 shown here only as an example) to the recorded in the motor housing 32 eccentric motor 31 is guided. The line 37 itself is then preferably guided to the control device 16, which is not shown here in detail, by means of which then the eccentric motor 31 can be controlled accordingly.

In order to ensure the liquid-tightness between the two housing parts of the motor housing 32 is between the cover part 33 and the Base part 35 also has a in the Fig. 4c only schematically illustrated annular seal 45 is provided.

How this in particular the Fig. 4d can be seen, the eccentric motor 31 here an eccentric weight 39, which generates an imbalance at a motor actuation, the vibrating plate 18 vibrational vibrations in such a way that this in the canister interior 12 relative to the upper and lower spring legs 19, 20 caused biasing force relative is moved to the canister interior space walls and thus vibrates or oscillates in the canister interior, which in the Fig. 3b is shown only symbolically by the vibration arrows 40. The vibrating plate 18 vibrating in such a way in the canister interior 12 causes the non-flowable or pumpable material accumulation 13 in the canister interior 12 (see FIG Fig. 3a ) is transferred back into the pumpable and removable by means of the cylinder-piston pump 10 state (see arrows 17 in the Fig. 3b ), whereby it is ensured that the entire medium can be withdrawn from the canister 3. Thus, such a solution is particularly suitable for thixotropic and / or thickening fluids, such as thixotropic and / or thickening color pigment preparations.

The cam motor 31 is preferably operated simultaneously with the control of the pump 10 of the trigger device.

In order to ensure that the vibrating plate 18 does not float, in particular in the case of fluids having a higher density, the vibrating plate 18 must be correspondingly heavy or, as is the case here, be weighted with a weight 41. This weight 41 is received in a recess 42 of the vibrating plate 18 and there releasably fixed by means of a clip connection 34.

As the exemplary illustrations further illustrate, an embodiment is advantageous in which the vibrating plate 18 substantially closes the canister cross-section and forms only the defined gap distance 28 to the canister interior side wall 23 to ensure that the vibrating plate 18 can oscillate in the canister possibly swing over the entire canister cross-section, which contributes significantly to ensure that as possible, the entire accumulation of material 13 can be transferred to the pumpable and peelable by means of the trigger device 10 state.

At this point it should be expressly mentioned that the resilient or oscillating mounting of the vibrating element (in the example shown, the mounting of the vibrating plate 18) is to be designed so that this swing at an actuation of the vibrator (in the example, the eccentric motor 31) relative to the Kanisterinnenraumwänden can. In the in the Fig. 3a shown rest position, however, holds the resilient or oscillating bearing the vibrating element (in the example, the vibrating plate) in the desired position.
