Description

[0001] The invention relates to a receiving container for receiving a bag filled with a flowable medium, in particular with a flowable dye composition, further to a method for feeding a receiving container with a bag filled with a flowable medium and to a device for volumetric dosing of flowable media.

[0002] Conventional dosing devices for flowable media typically have a receiving container as a storage tank, which is controlled by mechanical or electric pumps to withdraw the flowable medium. To prevent crystallization of solid particles in the flowable media, as is the case with flowable dye compositions, for example, it is already known to mix the flowable media using a mechanical stirrer to reduce or, ideally, prevent the solid particles from settling. This is often done in open systems, but there is a risk that the flowable media can thicken in the receiving containers, which ultimately leads to the media not being able to be pumped at all or only insufficiently, or to the lines or pumps of dosing units becoming blocked.

[0003] A further problem is that consumers and legislators are increasingly demanding the use of biocide-free flowable media, for example, biocide-free dye compositions. However, biocide-free media or dye compositions tend to form mold and dry out, so they decompose more quickly in open dosing systems and can therefore also become more easily contaminated. Accordingly, it is particularly advantageous, especially in conjunction with biocide-free flowable media, if they are handled in closed systems, as is known, for example, from EP2 067 716 A1. EP 2 067 716 A1 describes a so-called bag-in-box system in which a flexible and collapsible bag is accommodated in a bag-receiving space of a dimensionally stable receptacle housing.The bag has two connections that correspond to two openings in the receptacle housing. The receptacle has a cuboid-shaped outer basic shape. On the one hand, the bottom of which is inclined from the long sides towards the center, forming a groove in the direction of a discharge opening, and on the other hand, the bottom of which is inclined from the end of the receptacle housing opposite the discharge opening to the end with the discharge opening. This is to ensure that the medium always flows towards the discharge opening, thus leaving as little residue as possible in the bag. The dosing system is designed in such a way that not only does metered discharge occur, but the receptacle housing, including the bag, is part of a circulation system in which the flowable medium held in the bag can circulate.This effectively prevents crystallization of the flowable medium contained in the bag and, thanks to the closed system, prevents thickening of the flowable medium or its contamination.

[0004] However, with such a system, handling in connection with the bag, which must collapse inside the receptacle housing, is relatively complicated and impractical, especially in conjunction with dosing devices in which multiple bags containing different flowable media are provided. For example, residual or complete emptying of the bag is hardly possible due to the front-facing arrangement of the withdrawal point. This not only results in unnecessary costs for unused fluid remaining in the bag, but also makes recycling the bag time-consuming and therefore unprofitable due to the residue. When disposing of the bags, it may also be the case that, depending on the amount of residue remaining in the bag, they no longer have to be disposed of as residual waste, but rather as hazardous waste, which is a complex and costly process.Handling and loading the bags during a bag change also requires a high degree of attention and precision, creating the risk of incorrect installation. Furthermore, manual intervention near the coupling points poses a risk of contamination of the fluid itself. Finally, the asymmetrical arrangement of the coupling points leads to uncirculated "dead spaces" even when the fluid is recirculated.

[0005] It is therefore an object of the present invention to provide a receiving container or a container system for receiving a bag filled with a flowable medium, in particular with a flowable dye composition, which is easy to operate and which can be easily integrated into an industrially usable device for the volumetric dosing of flowable media, with which the flowable medium can also be circulated in the circuit.

[0006] This problem is solved by the features of the independent patent claims. Advantageous embodiments are the subject of the dependent claims.

[0007] According to claim 1, a receptacle or container system is provided for receiving a bag filled with a flowable medium, in particular with a flowable dye composition. The receptacle comprises a preferably dimensionally stable receptacle housing having a bag-receiving space into which a bag filled with a flowable medium can be inserted. The term "bag" is expressly to be understood here in a comprehensive sense as any container suitable for receiving flowable media and thus also expressly includes containers with rigid or dimensionally stable walls, for example, also canisters with rigid or dimensionally stable canister walls, although the use of a bag whose bag wall is at least partially flexible and / or foldable is preferred.This is preferably understood to mean a bag which is designed in the manner of a refill pack, as is used, for example, in connection with liquid soaps. The bag has two spaced-apart bag connections, to which two housing connections arranged on the receptacle housing are assigned. According to the invention, the receptacle housing has a base housing part, for example a base housing part designed in the manner of a receiving chamber, in which the bag is received in a use position such that a first bag connection is fluid-conductingly connected to a first housing connection assigned to the base housing part and a second bag connection is fluid-conductingly connected to a second housing connection assigned to the base housing part.Such an assignment of bag and container connections enables simple, quick, and above all, functionally reliable loading of the receptacle housing with a bag. In a particularly preferred specific embodiment, this is preferably achieved by connecting a bag with bag connections located opposite one another on the bag, preferably along a longitudinal axis of the bag, to housing connections arranged or formed on correspondingly assigned, opposite wall regions of the base housing part.

[0008] With such a basic idea, according to a first embodiment that is particularly easy to produce, a bag, which in this case is preferably designed as a canister with a dimensionally stable canister wall, can be inserted, for example by hand, into the base housing part, which is preferably designed in the manner of an open receiving chamber, preferably in such a way that the bag is first connected in a fluid-conducting manner with its first bag connection to the first housing connection assigned to the base housing part, before the second bag connection is then subsequently connected in a fluid-conducting manner to the second housing connection. The latter is preferably carried out, as will be described in more detail below, by means of a closing part coupled to the base housing part, which is preferably positively guided from a release position into a closing oris displaced into the use position, in which the second bag connection is fluidly connected to the second housing connection, which is then preferably arranged on the closing part. In this simple embodiment, the bag connections, which are preferably formed by connection pieces protruding from the bag, are thus preferably arranged, in particular with respect to the vertical axis in the use position, on opposite sides of the preferably elongated and / or rectangular bag in plan view, wherein it is preferably provided that the bag connections are placed symmetrically to one another along the longitudinal axis of the bag and / or that the housing connections are spaced apart from one another so far that the bag is pulled apart and / or stretched in the assembled state.

[0009] According to an alternative to this first embodiment and a particularly preferred embodiment, which enables particularly convenient and also functionally reliable handling, it is provided that the receiving container housing is designed in several parts and, in addition to the base housing part, has a displaceable magazine part, preferably coupled or connected to the base housing part, which magazine part can be displaced relative to the base housing part between a use position in which the bag connections can be connected or are connected to the housing connections in a fluid-conducting manner, and a loading and unloading position in which the magazine part can be equipped with a bag and / or in which a bag can be removed from the magazine part.

[0010] Such a magazine part enables particularly advantageous, simple, and functionally reliable loading of the receiving container with a bag. This is particularly advantageous in conjunction with devices that have a plurality of such receiving containers, as the loading process becomes more transparent overall. This also reliably prevents incorrect loading and allows the loading process to be carried out very quickly and thus cost-effectively. The same applies analogously to the removal of the bag. In this case, a magazine part according to the invention can then be easily and quickly unloaded in the loading and unloading position by removing the used bag from the magazine part and, for example, loading the magazine part with a new bag.

[0011] The magazine part can fundamentally be designed in different ways. A particularly preferred embodiment is one in which the magazine part forms at least a portion of the bag-receiving space, which is accessible in the loading and unloading position via a loading and unloading opening and / or into which the bag can be inserted in the loading and unloading position and / or from which the bag can be removed in the loading and unloading position. With such a specific embodiment, in which the magazine part forms at least a portion of the bag-receiving space, the bag can be safely and conveniently inserted into the magazine part via the loading and unloading opening, wherein the structural design of the magazine part already signals to the operator where and how to insert a bag.

[0012] In principle, the magazine part can be formed, for example, by a box- or cassette-like receiving element, preferably with a U-shaped cross-section, in which the cavity located between two opposite side wall regions forms at least a portion of the receiving space, preferably accessible in the loading and unloading position via a loading and unloading opening, in which a bag is at least partially received in the assembled or loaded state. Such a specific design of a magazine part provides a relatively compact structure overall that is also easy to manufacture.

[0013] According to another particularly preferred embodiment, the magazine part can also have two spaced-apart bag-holding areas on the magazine part side, to each of which one of the bag connectors is releasably secured. Such bag-holding areas enable a reliable, releasable retention of the bag during loading, thus reliably preventing incorrect bag placement in the receptacle housing.

[0014] According to a particularly preferred specific embodiment, the side wall regions of the magazine part formed by a box- or cassette-like receiving element extend at least partially between opposite end wall regions, with the bag-holding regions on the magazine part side then being formed accordingly on the opposite end wall regions. This not only ensures a functionally reliable arrangement of the bag on the magazine part, but also, for example, achieves an elongated alignment and arrangement of the bag in the magazine part.

[0015] The bag connections themselves are preferably formed by connecting pieces protruding from the bag, which can be releasably secured, preferably by means of a clamping and / or plug-in connection, to the respectively assigned bag-holding area on the magazine part side. Such connecting pieces are particularly well suited for supplying or removing the liquid medium from the bag and, in an advantageous dual function, can thus also be used to reliably secure the bag on or in the magazine part. For this purpose, according to an exemplary concrete embodiment, the connecting pieces are provided with a constriction area, for example an annular or angular one, which, when the bag is assembled, is partially encompassed by a bag-holding area on the magazine part side designed as a slotted opening.

[0016] It is further particularly advantageous if the bag connections and thus the bag holding regions on the magazine part side are arranged, preferably with respect to the vertical axis direction in the use position, on opposite sides of the preferably elongated and / or rectangular bag in plan view, wherein it is preferably provided that the bag connections are placed symmetrically to one another along the longitudinal axis of the bag. This ensures that the entire medium circulates in the desired manner, particularly when the receptacle together with the bag is used in a circulation system. As already explained above, it is particularly advantageous in this context too that the bag holding regions on the magazine part side are spaced far enough apart from one another that the bag is pulled apart and / or stretched in the assembled state.

[0017] The magazine part can in principle be a separate component that is completely removed or detached from the base housing part for loading and unloading a bag. However, this requires trained operators who are instructed in the operation of the device. In this context, a design in which the magazine part is held on the base housing part in a positively guided manner by means of a magazine part positive guide device and can be moved relative to the base housing part between the use position and the loading and unloading position is particularly advantageous. Using such a magazine part positive guide device, operation is significantly simplified because the magazine part is always positively guided in the same way and cannot be manipulated during its movement between the use position and the loading and unloading position. Incorrect operation is therefore virtually impossible.

[0018] The magazine part positive guide device preferably has an easily manufactured guide slot arrangement, for example, designed in the manner of a guide groove, on at least one base housing part, in which at least one sliding block of the magazine part is positively guided. It is preferably provided that the magazine part can be aligned, for example, pivoted open, during its displacement from the loading and unloading position to the use position so that the bag connections are associated with the housing connections. It is understood that a kinematic reversal is also possible, in which the guide slot arrangement is designed and arranged on the magazine part and the sliding block is arranged in the opposite direction on the base housing part. The term "sliding block" is expressly to be understood comprehensively here and basically refers to any element suitable for being positively guided in a guide slot.The term “sliding block” is therefore not limited to any specific design and is used solely for the sake of better comprehensibility and readability to represent any suitable engagement element in a guide block arrangement.

[0019] According to a particularly preferred specific embodiment, it can be provided, for example, that a guide slot on at least one base housing part extends upwards, preferably in a straight line, relative to the vertical axis. This is preferably done such that, in the loading and unloading position, the sliding block is arranged in an upper guide slot position in the guide slot, relative to the vertical axis, in which the magazine part is displaced, in particular pivoted away, from the base housing part, in particular for loading or unloading via a loading and unloading opening, preferably located at the top, for example such that the magazine part is arranged substantially horizontally.In this specific embodiment, the sliding block is also arranged in the use position, relative to the vertical axis, in the guide block in a lower guide block position, wherein the magazine part can be aligned, for example pivoted open, during its displacement from the loading and unloading position into the use position, in which the sliding block, starting from the upper guide block position, can be displaced along the guide block in a forced manner into the lower guide block position, such that the bag connections are assigned to the housing connections. In this case, it is further preferably provided that the magazine part forced guide device is suitable and designed to pivot the magazine part open by approximately 90° to 180° during its transfer from the loading and unloading position. Alternatively, a displacement can of course also be provided in which the magazine part cannot be moved away orIt is not pivoted open, but rather only moved linearly to be loaded with the bag. Such a positively guided movement ensures a particularly advantageous, simple, and reliable transfer of the bag, including the magazine section, into the desired position within the receiving container housing.

[0020] According to a further particularly preferred embodiment, the magazine part, which is forcibly moved into the use position by means of the magazine part positive guide device, is fluidly connected to a first housing connection assigned to the base housing part via a first bag connection. This achieves a particularly advantageous and functionally reliable fluid-conducting connection between the first bag connection and the first housing connection. According to a particularly preferred specific embodiment, it is particularly advantageous if the first bag connection is a lower bag connection, relative to the vertical axis direction in the use position, which is fluidly connected to a lower housing connection assigned to the base housing part as the first housing connection.

[0021] The base housing part can, quite generally, that is to say in particular regardless of whether a magazine part is provided or not (see also the explanations given at the beginning regarding the first embodiment of the invention), have a closing part arranged on the base housing part and displaceable relative to the base housing part, wherein the closing part has and / or forms the second housing connection. In connection with such an embodiment, it is particularly advantageous if the base housing part and the closing part are displaceable relative to one another between a release position, in which the base housing part and the closing part are displaced away from one another, in particular pivoted away from one another, and a closed position in which the second housing connection is fluidly connected to an associated second bag connection.The release position is characterized in particular by the fact that the base housing part and the closing part are displaced away from one another, in particular pivoted away from one another, in such a way that the insertion of the bag into the bag receiving space is permitted, for example by hand or by moving a possibly provided magazine part in the direction of the use position and the loading and unloading position. In conjunction with such an embodiment, when inserting the bag or during the positively guided movement of the magazine part into the use position, the fluid-conducting connection between the first housing connection and the first bag connection can first be established in a simple manner. To ensure that this can take place without hindrance, the closing part having the second housing connection is displaced away from the base housing, for example pivoted away.Once the magazine part has been moved towards the use position, the closing part with its second housing connection can then be moved into the closed position, in which the second housing connection is then also fluidly connected to the associated second bag connection. This enables very simple and functionally reliable assignment and connection of the bag connections to the associated housing connections, in conjunction with a compact design of the receptacle housing. The second bag connection is preferably an upper bag connection, relative to the vertical axis in the use position, which in the closed position is fluidly connected to an associated upper housing connection as the second housing connection, wherein it is preferably provided that the second housing connection arranged on the closing part lies above the upper bag connection in the closed position.This is particularly due to the compact design already mentioned, which ensures a functionally reliable assignment of the second housing connection to the second or upper bag connection.

[0022] In an embodiment with a magazine part, according to a further particularly preferred embodiment, the magazine part positive guide device has a magazine-part-side positive guide element, in particular a magazine-part-side stop element, by means of which the base housing part can be displaced relative to the closing part in the direction of its closed position when the magazine part is transferred into the use position, in particular shortly before the magazine part is reached or possibly only in the use position. This ensures in a simple and functionally reliable manner that, at the same time as the magazine part is moved into its use position, the base housing part or the closing part is also displaced essentially automatically and positively in the correct direction, namely towards its closed position, so that the second housing connection and the second bag connection are or are also assigned to one another accordingly.Alternatively or additionally, the same applies to the reverse process, i.e. when removing the magazine part: Accordingly, alternatively or additionally, it is provided that the magazine part positive guide device has a positive guide element on the base housing part side, in particular a stop element on the base housing part side, by means of which the base housing part can be displaced relative to the locking part in the direction of its release position, in particular when the magazine part moves from its use position to the loading and unloading position. This ensures that the locking part is always in the release position when the magazine part is no longer in its use position, so that a functionally reliable transfer of the magazine part from or into its use position is possible. This also takes place essentially automatically by means of the positive guide device, so that incorrect operation is ruled out.

[0023] Furthermore, according to a particularly preferred embodiment, regardless of whether the embodiment is with or without a magazine part, the base housing part and the locking part are positively guided by means of a locking part positive guide device and can be displaced relative to one another between the release position and the closed position. This ensures that the relative movement between the base housing part and the locking part takes place in a controlled and guided manner, reliably preventing incorrect operation.

[0024] This can be achieved, for example, according to a particularly preferred specific embodiment, in that the locking part positive guide device has a guide slot arrangement on the locking part, in which at least one sliding block of the base housing part is positively guided. The guide slot arrangement can be formed, for example, by a groove-like guide slot in which a sliding block can be displaced in a positively guided manner, whereby the term "sliding block" does not imply any restriction and encompasses any suitable engagement element for engagement in a guide slot. Furthermore, it can of course also be provided here, again in accordance with a kinematic reversal, that the guide slot arrangement is formed on the base housing part, while the at least one sliding block is then arranged in the opposite direction on the locking part.The positive guide is designed, for example, in conjunction with an embodiment in which a magazine part is provided, such that the base housing part can be displaced in the use position of the magazine part by a positively guided linear and pivoting movement from the release position to the closed position or vice versa.

[0025] According to a particularly preferred specific embodiment, it can be provided that the guide slot arrangement on the closing part has a lower guide slot which is assigned to a lower region of the base housing part with respect to the vertical axis direction of the receiving container housing part and which extends upwards, preferably approximately rectilinearly and / or in the manner of a longitudinal slot, and in which a first sliding block of the base housing part is received in a positively guided manner so as to be longitudinally displaceable, wherein the closing part is pivotable about the first sliding block for pivoting the closing part between the release position and the closed position.With such a configuration, the guide slot arrangement on the closing part can then further comprise an upper guide slot associated with an upper region of the base housing part, relative to the vertical axis of the receptacle housing part. This upper guide slot is L-shaped and has an approximately horizontal first L-leg and an approximately vertical second L-leg, in which a second sliding block of the base housing part is positively received. Such a design results in a particularly advantageous and functionally reliable positively guided displacement between the desired positions. This can be the case, for example, as follows:

[0026] If the second sliding block, which is positively guided in the upper guide slot, is in the closed position in the area of ​​the vertically running second L-leg, then a displacement of the closing part along the vertically running second L-leg in the direction of the adjoining horizontally running first L-leg is released for disengaging the second housing connection from the second bag connection, wherein the closing part can be pivoted around the first sliding block in this position with a positively guided displacement of the horizontally running L-leg along the second sliding block, so that the second housing connection can be displaced away from the bag and thus from the second bag connection into the release position.Furthermore, in a correspondingly reversed manner from the release position, in order to establish the fluid-conducting connection between the second housing connection and the second bag connection, the closing part can be pivoted about the first sliding block with a forced displacement of the horizontally running L-leg along the second sliding block into the region of the vertically running L-leg, so that the second housing connection is displaced towards the bag and thus the second bag connection, in particular the second housing connection is arranged in the region above the second bag connection.As a result, the closing part can then, starting from this position, be moved with the vertical L-leg forcibly guided along the second sliding block and with the lower guide link forcibly guided along the first sliding block into the closing position, in which the second housing connection is fluidly connected to the second bag connection.

[0027] According to another particularly preferred embodiment, the base housing part and the locking part are releasably locked in the closed position by means of a locking device. This easily ensures that the locking part reliably remains in the desired position in the use position.

[0028] Furthermore, according to a further preferred embodiment, at least one spring element, preferably a leaf spring, is provided, by means of which the closing part is pretensioned away from the base housing part toward the release position and / or by means of which the second housing connection is pretensioned away from the second bag connection. This enables, in particular, an advantageous semi-automatic transfer of the closing part into the release position or a decoupling of the second housing connection from the second bag connection, so that incorrect operation in this regard is reliably and safely excluded.Particularly advantageous in this context is an embodiment according to which it is provided that the at least one spring element is coupled to the locking device in such a way that the at least one spring element displaces the closing part away from the base housing part and / or lifts the second housing connection from the second bag connection when the lock is released.

[0029] Furthermore, it is preferably provided that each of the housing connections is connected to a line, preferably a hose line. This allows for the advantageous integration of such a receptacle into a dosing device, particularly into a circulation system of a device for the volumetric dosing of flowable media.

[0030] In conjunction with such lines or hose lines, it is also advantageous if the line or line or hose line connected to the second housing connection, based on the vertical axis in the use position, is guided inside the closing part along a closing part wall downwards in the direction of a bottom wall of the base housing part, in which the first housing connection is formed, so that the lines or hose lines connected to the two housing connections lead away from the underside of the receptacle housing. This results in advantageous routing of the lines or hose lines within the receptacle or within a device in which the receptacle is used, so that they run in an orderly manner and are essentially inaccessible from the outside of the receptacle or in the device.

[0031] The base housing part itself can fundamentally be designed in different ways, but is preferably formed by an open receiving chamber, preferably open upwards with respect to the vertical axis direction, preferably a box-like or cassette-like receiving chamber. It is preferably provided here that the base housing part designed as a receiving chamber is designed to receive a bag and / or a magazine part in the basic position, preferably essentially adapted to the shape and contour. This results in an overall compact design of the receiving container housing that takes up little installation space and volume. Furthermore, in the case of an embodiment with a magazine part, it can be ensured that not only the magazine part, but also the bag received therein is securely stowed inside the receiving container housing and is therefore not accessible from the outside.

[0032] According to a further alternative or additional embodiment, again for example in the case of an embodiment with a magazine part, it is preferably provided that the base housing part and the magazine part jointly form the bag receiving space. This also allows for a reduction in manufacturing costs and the realization of an overall compactly constructed receptacle housing.

[0033] The locking part preferably forms an end wall arranged laterally on the outside of the base housing part, which is displaced away from the base housing part in the release position.

[0034] This allows for easy loading of the base housing part with a bag or, alternatively, with a magazine part including the bag in the release position. In an embodiment with a magazine part, it is preferably provided that the closing part and the magazine part can be displaced in opposite directions away from the base housing part with respect to the side view of the receptacle housing and with respect to the loading and unloading position of the magazine part or the release position of the closing part. Such a configuration allows, on the one hand, a particularly compact design of the receptacle housing as a whole to be realized, while at the same time ensuring that the different housing parts do not interfere with one another in their different functional positions.

[0035] Specifically, it can further be provided that the locking part forming an end wall arranged laterally on the outside of the base housing part engages around the base housing part, preferably two spaced-apart side wall regions of the base housing part, at least in regions and with at least one end wall leg at the edge and / or outside, preferably on two opposite sides, wherein it is preferably provided that the locking part positive guide device is formed between the at least one end wall leg and the base housing part. With such a construction, a particularly advantageous and functionally reliable guidance of the locking part on the base housing part is achieved, which in a particularly preferred and advantageous dual function simultaneously also serves to form the locking part positive guide device between the locking part and the base housing part.

[0036] According to a further particularly preferred embodiment in conjunction with an embodiment having a magazine part, it is provided that the magazine part is releasably locked to the base housing part in the use position by means of a locking device, in particular by means of a spring element, wherein it is preferably provided that the locking device for the releasable locking of the magazine part and the base housing part simultaneously also forms the locking device for the releasable locking of the base housing part and the closing part. This ensures that the displacement of the magazine part relative to the base housing part is only permitted when the lock is released, and is blocked when the lock is not released. This contributes significantly to the functional reliability of the receptacle and thus also to a dosing device in which the receptacle is used or inserted.A releasable spring lock, as an example of a preferred locking device, preferably uses a spring as the central element in the locking mechanism. The spring is placed under tension to hold a closure or latch in position. When it is necessary to release the lock, the tension on the spring is reduced, and the closure or latch can be released to open the connection. This ensures a functionally secure locking of the parts, particularly in their use position.

[0037] The bag itself, particularly if it is designed as a flexible and / or collapsible bag, is preferably designed as a hanging bag. A hanging bag is understood to be a bag which - unlike a stand-up pouch or a stand-up pouch - has no base and therefore cannot stand freely. This has the advantage that the bag can be designed (for example conically), particularly in the area of ​​the opposite sides (relative to the vertical axis of the bag in the position of use), on which the bag connections are formed and provided, so that the flowable medium in the bag always flows towards the lower bag connection, without any significant residue remaining in the bag, thereby ensuring that essentially the entire contents of the bag can be circulated in a circulation system.Of course, such a geometry can also be realized with bags that are dimensionally stable and / or designed as canisters.

[0038] As already mentioned, the bag can in principle also be designed as a dimensionally stable bag or canister with a rigid bag wall, but is preferably designed as a flexible and / or collapsible bag with a bag wall that is at least partially flexible and / or collapsible. The advantage of a flexible and / or collapsible bag lies in particular in the fact that when a dose of the flowable medium is withdrawn, a negative pressure is built up inside the bag, which causes the bag to contract, thereby ensuring that essentially the entire contents of the bag can be removed from the bag. The term flexible and / or collapsible bag means that the bag has flexible bag wall areas at least in some areas, so that it can be collapsed, folded, or compacted in some other way. An example material for such a bag is plastic.

[0039] The receiving container housing and thus in particular the base part housing together with any additional housing parts provided (in particular the magazine part and / or the closing part) can in principle have any desired shape, but is preferably cuboid-shaped and / or dimensionally stable for reasons of ease of manufacture and compact construction, in particular for industrial or mechanical arrangements with several receiving containers arranged next to one another or one above the other in a magazine-like manner.

[0040] According to a further particularly preferred embodiment, the bag has a first bag connection which, relative to the vertical axis in the use position of the bag, forms the geodetically lowest point on the bag and thus a lower bag connection, preferably with an inner bag bottom wall that tapers towards the lower bag connection, and / or the bag has a second bag connection which, relative to the vertical axis in the use position of the bag, is higher than the first bag connection, preferably the geodetically highest point on the bag and thus forms an upper bag connection. As already explained above, such a design and arrangement of the bag not only enables functionally reliable circulation of the flowable medium into and out of the bag, but also removal of the flowable medium such that little to no residue remains in the bag.

[0041] The object of the invention is further achieved by a method for feeding a receiving container with a bag filled with a flowable medium, in particular with a flowable dye composition, wherein the receiving container has a receiving container housing with a bag receiving space into which a bag filled with a flowable medium can be inserted, wherein the bag has two spaced-apart bag connections, to which two housing connections arranged on the receiving container housing are assigned.According to the invention, it is provided that the receiving container housing has a base housing part, preferably a base housing part designed in the manner of a receiving chamber, in which the bag is received in a use position in such a way that a first bag connection is fluid-conductingly connected to a first housing connection assigned to the base housing part and a second bag connection is fluid-conductingly connected to a second housing connection assigned to the base housing part, preferably connected in such a way that the bag is connected to the housing connections, which are arranged or formed on correspondingly assigned opposite wall regions of the base housing part, with the bag connections lying opposite one another on the bag, preferably along a longitudinal axis of the bag.

[0042] The advantages resulting from such a process are identical to those already explained in detail in connection with the receiving container according to the invention. To avoid repetition, reference is made to those explanations.

[0043] The invention further claims a device for the volumetric dosing of flowable media, in particular for dosing flowable dye compositions, with at least one receiving container as already described above. In conjunction with such a configuration, it is provided that the housing connections of each receiving container are integrated into a circulation system, by means of which the flowable medium can be circulated in the circuit, including the bag as a flow path. Furthermore, it is provided that a dosing path branches off from the circuit, via which the flowable medium can be released from the circuit. Here, too, the advantages have already been explained in detail in connection with the evaluation of the receiving container. To avoid repetition, reference is made to the explanations therein.

[0044] In conjunction with such a device, it is further particularly advantageous to provide a plurality of receiving containers whose bags at least partially contain different flowable media. Preferably, the plurality of receiving containers are arranged in a row, preferably one below or next to each other, and / or the receiving containers can be controlled individually or in groups via a central control device. This provides an overall device for the volumetric dosing of flowable media, in particular for dosing flowable dye compositions, with which a wide variety of flowable media can be dosed.

[0045] The invention is explained in more detail below with reference to a drawing, merely by way of example.

[0047] In the Figure 1is a front view of an exemplary embodiment of a device 1 according to the invention for dosing flowable media, for example for dosing flowable dye compositions, which has a plurality of receiving containers 2, here for example cuboid-shaped, which are arranged next to one another in a row.

[0048] The device 1 has a central control device 3, via which the receiving containers 2 can be controlled individually or in groups, for example in such a way that at a specific time from a specific receiving container 2 a specific amount of the material contained in the receiving container 2 in a bag 7 (see for example Figure 4 ) is drawn off from the bag 7 or the receiving container 2 and fed via a dosing valve 4 (see Figure 1) is dosed into a container placed there, but not shown here. For example, different dye compositions can be stored in the receiving containers 2, which are then dosed, for example, into a container containing a base color, for example, a white base color.

[0049] Although the invention is explained above and below in connection with dye compositions, this does not mean that other flowable media cannot also be metered using such a device. For example, the device according to the invention can also be used for metering oils, resins, adhesives, or the like, to name just a few examples, although use in connection with dye compositions is the preferred application.

[0050] As is particularly evident from the Figure 4As can be seen, each of the receptacles 2 is designed here as a bag-in-box system and has a receptacle housing 5, described in more detail below, which is preferably dimensionally stable and has a bag-receiving space 6. A preferably flexible and / or collapsible bag 7 made of, for example, a plastic material is inserted into the bag-receiving space 6, which bag is filled with a flowable medium, for example with a specific dye composition.

[0051] As can be seen from the Figure 4 As can be seen further, the bag 2 has spaced-apart bag connections 8, 9, which have a, with respect to the Figure 4 shown vertical axis direction x of the receiving container 2 or the bag 7, form an upper bag connection 8 and a lower bag connection 9.

[0052] In the use position of the bag 7 shown here, the upper bag connection 8 is fluidly connected to an upper housing connection 10 of the receptacle housing 5 and the lower bag connection 9 is fluidly connected to a lower housing connection 11 of the receptacle housing 5.

[0053] As can be seen from the Figure 4As can be seen further, both the upper housing connection 10 and the lower housing connection 11 are integrated into a circulation system of the device 1 via lines, for example via hose lines 12, 13, by means of which the flowable medium stored in the bag 7 can be circulated in the circuit and also dispensed in doses via the dosing valve 4. For this purpose, the circulation system 14 has, for example, a pump as a conveying device 15, which can be controlled and actuated via the central control device 3. When the conveying device 15 is actuated by means of the control device 3, medium is pumped out of the bag 7 via the extraction line, which is designed here merely as an example as a hose line 12, until the pump or the conveying device 15 is stopped again.

[0054] A directional control valve 16 is also connected to the circulation system 14 downstream of the conveying device 15. This directional control valve can also be controlled and actuated by means of the control device 3 and by means of which the medium drawn off from the bag 7 is conveyed either via the dosing line 17 to the dosing valve 4, from which the drawn off amount of medium can then be dosed, for example, into a container. Alternatively, the dosing line 17 can also be shut off by means of the directional control valve 16 and the flow connection to the return line, designed here as a hose line 13, can be established. By means of this return line, the medium pumped out via the lower bag connection 9 or the lower housing connection 11 is conveyed to the upper housing connection 10 and thus to the upper bag connection 8 and thus back into the bag 7, so that the medium circulates in the circuit.This reliably prevents crystallization of the flowable medium contained in the bag and, due to the closed system, also reliably prevents thickening of the flowable medium or its contamination.

[0055] If the amount of flowable medium, which is for example a dye composition, held in the bag 7 is used up, the bag 7 must be removed from the bag-holding space 6 of the receptacle 2, for which purpose the receptacle housing 5 is designed in several parts and has a displaceable magazine part 18 which can be inserted into the Figure 3 shown loading and unloading position, in which the bag 7 can be easily removed from the magazine part 18 and a new bag 7 can be inserted into the magazine part 18. This will be explained below with reference to the Figures 5 to 13b explained in more detail using a receiving container 2 as an example: As this can be seen from the overview of the Figures 4 and 5 As can be seen, the magazine part 18 is arranged relative to a base housing part 19 between the Figure 4 shown use position, in which the bag connections 8, 9 are fluidly connected to the housing connections 10, 11, and in the Figure 5 shown loading and unloading position, in which the magazine part 18 can either be equipped with a bag 7 or in which a bag 7 can be removed from the magazine part 18 and a new bag 7 can be inserted if necessary.

[0056] The magazine part 18 is formed here, for example, by a box-like or cassette-like receiving element which has a substantially U-shaped cross-section, wherein the cavity located between two opposite side wall regions 21, 22 of the magazine part 18 forms a partial region of the bag receiving space 6 accessible via a loading and unloading opening 20, in which a bag 7, as shown in the Figure 6shown, is recorded at least in part in the assembled or populated state.

[0057] As can be seen from the summary of the Figures 5 and 6 As can be seen further, the side wall areas 21, 22 of the magazine part 18 extend between opposite end wall areas 23, 24 of the magazine part 18. On these opposite end wall areas 23, 24, magazine part-side bag holding areas 25, 26 are formed, to each of which one of the two bag connections 8, 9 is detachably held. For this purpose, the bag connections 8, 9, as shown in the Figure 5 and 6 is clearly visible, is formed by connecting pieces 27, 28 projecting from the bag 7 on opposite sides, which here only exemplarily have an annular constriction area 29, 30, which in the assembled state of the bag 7 (see Figure 6) is partially encompassed by a bag-holding region 25, 26 on the magazine part side, designed as a slotted opening, although this is not shown in detail here. This detachable connection between the connecting pieces 27 and 28 and the bag-holding regions 25, 26 is preferably designed as a clamp and plug connection, which ensures that the connecting pieces 27, 28 forming the upper and lower bag connections 8, 9 are securely held on the respectively assigned bag-holding regions 25, 26.

[0058] As this is further shown in particular by the Figure 6As can be seen, the bag connections 8, 9 and thus the bag holding areas 25, 26 on the magazine part side are arranged here by way of example on opposite sides of the elongated and, in plan view, approximately rectangular bag 7, wherein the magazine part-side bag holding areas 25, 26 on the magazine part 18 are spaced apart from one another so far that the bag 7 is pulled apart or stretched in the assembled state.

[0059] The magazine part 18 is furthermore held in a positively guided and displaceable manner on the base housing part 19 by means of a magazine part positive guide device 31 and is displaceable relative to the base housing part 19 between the use position and the loading and unloading position. For this purpose, the magazine part positive guide device 31 has a guide slot 32 on the base housing part 19, which here, with respect to the vertical axis direction x of the base housing part 19, extends upwards, for example, essentially rectilinearly and in the manner of a guide slot or guide groove. A sliding block 33 arranged on the magazine part 18 is positively guided in this guide slot 32, as described below, in such a way that the magazine part 18 is pivoted open during its displacement from the loading and unloading position into the use position such that the bag connections 8, 9 are or are assigned to the housing connections 10, 11.For this purpose, the sliding block 33 is located in the loading and unloading position, relative to the vertical axis direction x, in the guide block 32 in a position shown in the . Figure 5 and 6 illustrated upper guide slot position 34, in which the magazine part 18, as already described above, is pivoted away from the base housing part 19 and in which the magazine part 18 is arranged substantially horizontally, so that a convenient loading or removal of the bag 7 via the loading and unloading opening 20 located at the top is possible.

[0060] During the Figures 7 , 8 , 9 and 10a shown continuous or step-by-step and forced transfer of the magazine part 18 from the Figures 5 and 6shown loading and unloading position in the direction of the use position, the sliding block 33 is displaced downwards along the guide block 32 until the sliding block reaches a lower guide block position 35 in which, as shown in the Figure 11 shown, the magazine part 18 together with the bag 7 is moved into the use position in which the lower bag connection 9 is fluidly connected to the lower housing connection 11.

[0061] This transfer of the magazine part 18 can be carried out easily and conveniently by an operator in that the operator grasps the magazine part 18, for example, at the handle part 36 and pushes it into the base housing part 19 designed as an upwardly open receiving chamber, in which the magazine part 18 is preferably received in the basic position in a substantially shape and contour-adapted manner, wherein the base housing part 19 and the magazine part together form the bag receiving space 6.

[0062] During this forced displacement of the magazine part 18 together with the bag 7 in the direction of the use position, the magazine part 18 is pivoted upwards by approximately 90°, starting from the approximately horizontal loading and unloading position, in order to align the bag 7 in the vertical axis direction x and to transfer the bag connections 8, 9 into the position desired for the fluid-conducting connection with the housing connections 10, 11.

[0063] As can be seen from Figures 5 et seq., the receiving container housing 5 further comprises a closing part 37 arranged on the base housing part 19 and displaceable relative to the base housing part 19 or, in the exemplary embodiment shown here, pivotable, which has the upper housing connection 10.

[0064] The base housing part 19 and the locking part 37 are arranged relative to each other between a Figures 5 to 11shown release position, in which the base housing part 19 and the closing part 37 are pivoted away from each other in such a way that the displacement of the magazine part 18 in the direction of the use position or in the direction of the loading and unloading position is released, and one in the Figure 13a shown closed position, in which the upper housing connection 10, as well as in the Figure 4 schematically shown, is fluidly connected to the associated upper bag connection 8.

[0065] As this is particularly evident in the comparison of Figures 10b and 12b shows, the magazine part positive guide device 31 has a magazine part-side positive guide element in the form of a stop element 38, by means of which the base housing part 19 shortly before reaching the use position of the magazine part 18 (see Figure 10a ) or, if necessary, only in the use position of the magazine part 18 (see Figure 11) can be displaced relative to the locking part 37 in the direction of the closed position. This occurs specifically when the stop element 38 comes into contact with the base housing part 19 and displaces it in the direction of the locking part 37 (arrow 39).

[0066] As can be seen from the Figures 10b and 12b As can be seen further, the magazine part positive guide device 31 also has a base housing part-side positive guide element in the form of a further stop element 40, by means of which the base housing part 19 in the reverse manner, i.e. during the transition of the magazine part 18 from its use position into the Figure 5 and 6 The loading and unloading position shown can be displaced relative to the locking part 37 in the direction of its release position (arrow 41).

[0067] As can be seen from the summary of the Figures 5 to 13bAs can also be seen further, the base housing part 19 and the locking part 37 are positively guided by means of a locking part positive guide device 42 and can be displaced relative to each other between the release position and the closed position. Specifically, this locking part positive guide device 42, as can be seen, for example, from the Figures 5 to 8 As can be clearly seen, the locking part 37 has a lower guide slot 43 which is assigned to a lower region of the base housing part 19 in relation to the vertical axis direction x of the base housing part 19 and which, here by way of example, extends upwards in an approximately straight line and in the manner of a longitudinal slot and in which a first sliding block 44 of the base housing part 19 is positively guided in a longitudinally displaceable manner, the locking part 37 being pivotable about the first sliding block 44 for pivoting the locking part 37 between the release position and the closed position.

[0068] As can be seen from the Figures 5 to 8Furthermore, as can be clearly seen, the locking part positive guide device 42 on the locking part 37 further comprises an upper guide slot 45, which is assigned to an upper region of the base housing part 19, in relation to the vertical axis direction x of the base housing part 19 (see also the Figures 10b , 12b and 13b ), which is L-shaped and has an approximately horizontally extending first L-leg 46 and an approximately vertically extending second L-leg 47, and in which a second sliding block 48 of the base housing part 19 is positively received.

[0069] The locking part 37 here forms an end wall arranged laterally on the outside of the base housing part 19, which in the release position is displaced away from the base housing part 19, in such a way that the locking part 37 and the magazine part 18, with reference to the Figures 5 to 13bshown side view of the receiving container housing 5 and with respect to the loading and unloading position of the magazine part 18 or the release position of the closing part, can be displaced in opposite directions from the base housing part 19. In the exemplary embodiment shown here, the closing part 37, which forms an end wall arranged laterally on the outside of the base housing part 19, also encompasses the base housing part 19 on the outside, specifically on two opposite sides with an end wall leg 49, 50 each. The closing part positive guide device 42 is preferably formed between each of the end wall legs 49, 50 and the associated wall region of the base housing part 19.

[0070] As this is particularly evident in the comparison of Figures 10b , 12b and 13b in conjunction with, in particular, the Figures 5 to 8shows, in order to establish the fluid-conducting connection between the upper housing connection 10 and the upper bag connection 8, the closing part 37 is pivoted about the first sliding block 44 with a positively guided displacement of the horizontally running first L-leg 46 along the sliding block 48 into the transition area to the vertically running second L-leg 47, so that the upper housing connection 11 comes to rest in the area above the upper bag connection 8, so that the closing part 37, starting from this position, can be moved with the second L-leg 47, positively guided along the second sliding block 48 and with the lower guide link 43, positively guided along the first sliding block 44 into the closed position, in which, as in the Figure 13a and 13b shown, the upper housing connection 10 is fluidly connected to the upper bag connection 8.

[0071] Conversely, when the second sliding block 48, which is positively guided in the upper guide block 45, is in the closed position in the region of the vertically running second L-leg 47, the closing part 37 can be displaced along the vertically running second L-leg 47 in the direction of the adjoining horizontally running first L-leg 46, so that the upper housing connection 10 is uncoupled or lifted off the upper bag connection 8, wherein the closing part 37 can be pivoted about the first sliding block 44 in this position with the horizontally running first L-leg 46 being positively displaced along the second sliding block 48, so that the upper housing connection 10 can be displaced away from the bag 7 and thus away from the upper bag connection 8 into the release position.

[0072] As this is further shown, for example, in the Figure 13aAs can be clearly seen, the magazine part 18 is releasably locked to the base housing part 19 in the use position by means of a spring element 51. For this purpose, the handle part 36 is preferably designed such that a spring locking element 52 is mounted thereon, which can be moved according to the arrow 53 (see Figure 13a ) can be pulled towards the handle part 36 to release the spring lock and the magazine part 18 from the Figure 13a shown use position into the example shown in the Figures 5 and 6 shown loading and unloading position. When returning to the use position, the spring locking element 52 is then tensioned again accordingly and releasably locked.

[0073] In the exemplary embodiment shown here, the spring locking element 52 also releasably locks the base housing part 19 and the locking part 37 together in their closed position, so that when the spring locking element 52 is actuated, the locking between the base housing part 19 and the locking part 37 is also released. As can be clearly seen from the Figures 5 and 6As can be seen, a leaf spring is provided between the base housing part 19 and the closing part 37 as a pretensioning or spring element 58. By means of this spring element 58, the closing part 37 is pretensioned away from the base housing part 19 in the direction of the release position, wherein the spring element 58 is also designed such that it can also lift the second housing connection 10 from the second bag connection 8. This ensures that the closing part 37 is moved automatically when the spring locking element 52 is released. The spring element 58 is designed and constructed such that when the spring locking element 52 is released, it initially lifts the closing part 37, whereby the first sliding block 44 and the second sliding block 48 move along their respectively assigned guide blocks 43 and 45, relative to the image plane orVertical axis direction, are displaced downwards, before the spring element 58 then causes the pivoting of the locking part 37 by displacing the second sliding block 48 along the L-leg 46 of the upper guide block 45.

[0074] Here too, the spring locking element 52 is then tensioned again accordingly and releasably locked when the locking part 37 is manually returned to the closed position or use position in order to releasably lock the locking part 37 to the base housing part 19.

[0075] As can be clearly seen from the figures, for example from the Figure 12a or 13a, the lower bag connection 9 of the bag forms the geodetically lowest point on the bag 7, with an inner bag bottom wall 54 that tapers towards the lower bag connection 9, while the upper bag connection 8 here forms the geodetically highest point on the bag 7.

[0076] From the Figures 5 ff. it is further clearly visible that the upper housing connection 10 is connected to the hose line 13 and the lower housing connection 11 is connected to the hose line 12, whereby the hose line 13, as can be seen for example from the Figure 9 as can be seen, is guided in the interior of the closing part 37 along a closing part wall 55 downwards in the direction of a bottom wall 56 of the base housing part 19, in which the lower housing connection 11 is also arranged or formed, so that the hose lines 12, 13 connected to the two housing connections 10, 11 lead away from the underside 57 of the receiving container housing 5.

[0077] In the Figure 14 is based on the representation of the Figure 5a merely extremely schematic principle representation of an exemplary alternative embodiment of a receiving container 2 according to the invention without a displaceable magazine part and with a displaceable closing part 37. In this embodiment, the bag 7, which is preferably designed as a canister with a dimensionally stable canister wall, is then inserted, for example, by hand into the base housing part, which is preferably designed in the manner of an open receiving chamber, in such a way that the bag 7 is again initially fluidically connected with its first bag connection 9 to the first housing connection 11 assigned to the base housing part 19, before then by manually closing the closing part 37 analogously to the first embodiment of the Figures 1 to 13b a forced displacement of the locking part 37 by means of the locking part forced guide device 42 from the position shown in the Figure 14 shown release position into the position shown in the Figure 13ashown closed position or use position, in which the second bag connection 8 is fluidly connected to the second housing connection 10 arranged on the closing part 37. Here, too, the closing part 37 is then preferably releasably locked to the base housing part 19 in the use position, although this is not shown here. List of reference symbols
