Description

[0001] The present invention relates to a device for filling tanks, and in particular for filling tanks without contamination. Such a device is known, for example, from WO 2014 / 005 951 A1. The present invention is also specifically directed to a device, for example, for transferring liquid plant protection products from small containers, such as canisters or bottles, into larger containers, such as drums or tanks. Devices of this type are generally known in the prior art, but these have not yet allowed for the cleaning of internal valve components. The device described in WO 2014 / 005 951 A1 already allows for the rinsing of valve components. Further devices of this type are known, for example, from DE 296 06 472 U1, US 2016 / 0370 217 A1, EP 0482 103 B1, or DE 16 90 389 U.

[0002] WO 2014 / 005 951 A1 is hereby incorporated in its entirety by reference into the present application. In particular, reference is made to the character description therein (pages 13-20 of the description and the associated figures), and these are also incorporated into the disclosure of the present application. However, prior art has shown that dosing the liquids to be filled or checking the transferred liquids is often difficult to achieve.

[0003] The present invention is therefore based on the objective of providing such a device for transferring liquids, which also enables verification of the transferred volumes and improved handling of such measuring devices. These objectives are achieved according to the invention by the subject matter of the independent claims. Advantageous embodiments and further developments are the subject of the dependent claims.

[0004] An inventive device for filling tanks, for example from a canister, comprises a first adapter assembly which is suitable and intended for at least temporary attachment to the canister and which includes a feed device through which a flowable medium can be directed from the canister into the tank. Furthermore, the device has a cleaning agent connection for supplying a cleaning fluid to at least one component of the device. However, permanent attachment to the canister would also be conceivable.

[0005] According to the invention, the device has a further receiving container for temporarily receiving the flowable medium to be filled into the tank, and preferably also a cleaning device for cleaning this receiving container, wherein preferably this cleaning device has at least one rinsing agent channel that allows cleaning fluid to flow from the rinsing agent connection to the receiving container.

[0006] Preferably, the device also has a second adapter device suitable for at least temporary (but possibly also permanent) and indirect attachment to the tank and / or the receiving container.

[0007] Therefore, within the scope of the present invention, an additional receiving container is proposed which—as mentioned above—serves in particular for the temporary holding of the liquid to be dispensed. This receiving container can also enable the measurement of the liquid being transferred. Advantageously, the device has a filling opening equipped with a valve, through which the product can be filled. The applicant reserves the right to also claim protection for a device that comprises only the aforementioned receiving container, i.e., not necessarily a cleaning device for cleaning the receiving container or a ventilation device for venting or aerating the receiving container.

[0008] In a further advantageous embodiment, the device includes a tank adapter for attachment to a tank. Advantageously, the device includes a first coupling element. Particularly preferably, said tank adapter includes a tank mounting flange for attachment to the tank.

[0009] In particular, in an open position, the device provides a fluid connection between a canister fastening means, in particular a canister fastening flange, and the tank fastening means, in particular a tank fastening flange, and in a closed position, it closes the fluid connection between the canister fastening flange and the tank fastening flange.

[0010] By placing the flushing connection on the second adapter device, i.e., on the tank adapter, it is possible to flush the connection area between the tank adapter and the canister adapter both when the canister is completely empty and when only a portion is removed.

[0011] Providing the rinsing port on the tank adapter also has the advantage of reducing the weight of the canister adapter. This, in turn, simplifies handling for the user, as they typically first screw the canister adapter onto the canister and then connect this unit of canister and adapter to the tank adapter. Within the scope of the invention, it is also conceivable that the canister adapter is an integral part of the canister. It is therefore advantageous if the canister adapter is designed to be as cost-effective as possible.

[0012] In a further advantageous embodiment, the feed device is designed as a canister adapter, and this canister adapter preferably also has a canister mounting flange for attachment to a canister. A second coupling element may also be provided. The first coupling element mentioned above and the second coupling element can preferably be connected to or disconnected from each other. In other words, the tank adapter and the canister adapter are preferably detachably connected to each other via the first and second coupling elements.

[0013] The aforementioned valve of the device preferably allows a fluid connection between the canister adapter or canister mounting flange and the tank mounting adapter or tank mounting flange in an open position. In a closed position of this valve, this fluid connection between the canister mounting adapter and the tank mounting adapter is preferably closed.

[0014] In a further advantageous embodiment, said first and second coupling part can, in an open position of the valve or device, establish a first fluid connection between the canister mounting flange and the tank mounting flange, as well as a second lockable fluid connection between the rinsing agent connection and the canister adapter.

[0015] By attaching the flushing connection to the tank adapter, it is possible to flush the connection area between the tank adapter and the canister adapter under different operating conditions, for example, when the canister is completely empty or when only a portion is being dispensed. In a further advantageous embodiment, the cleaning device for cleaning the receiving container has at least one outlet element, which is oriented such that cleaning fluid exiting this outlet element reaches an inner wall of the receiving container. In this way, efficient cleaning of the receiving container or its inner wall is possible. In a further advantageous embodiment, the at least one outlet element is designed such that the cleaning fluid reaches an upper edge of the inner wall of the receiving container.Gravity allows the liquid to flow downwards, thus essentially cleaning the entire surface of the receiving container.

[0016] In a further advantageous embodiment, the cleaning device has a second outlet element which is oriented such that cleaning fluid exiting this second outlet element also reaches the inner wall of the receiving container. This allows both the first and second outlet elements to direct the cleaning fluid – preferably at different points – onto the receiving container. In this way, a thorough cleaning of the receiving container can be facilitated.

[0017] In an advantageous embodiment, the two outlet elements are arranged opposite each other. For example, the outlet elements can direct the cleaning fluid onto areas of the receiving container that are opposite each other or that are offset from each other by a circumferential angle of 180°. It would also be possible to provide more than two outlet elements. However, it is advantageous if the outlet elements, regardless of their number, are evenly distributed around the circumference of the device.

[0018] In a further advantageous embodiment, the cleaning device has at least one outlet element oriented such that the cleaning fluid exiting this second outlet element also exits the receiving container in a direction tangential to its circumferential direction. Preferably, the receiving container is therefore subjected to a direction that has both a radial and a tangential component. This approach allows the cleaning fluid to be applied precisely to the receiving container or its inner wall and thus distributed very evenly across the inner surface of the receiving container. In this way, highly efficient cleaning of the receiving container is possible.

[0019] For example, it is possible that the liquid gets onto the receiving container in such a way that the liquid runs or trickles downwards in a spiral shape, even under the influence of gravity.

[0020] Advantageously, the receiving container has a rotationally symmetrical shape and, in particular, a circular or conical shape.

[0021] In a further advantageous embodiment, the outlet elements are arranged such that the cleaning fluid is directed at an angle onto the inner wall which deviates by less than 20°, preferably less than 15° and preferably less than 10° from the tangential direction.

[0022] Advantageously, the cleaning fluids exit the two outlet elements in opposite directions. This ensures that the cleaning fluid exiting both outlet elements is applied to the containers in the same direction of rotation or tangential direction. For example, this allows the cleaning fluid to flow clockwise or counterclockwise along the receiving container or its wall.

[0023] In a further advantageous embodiment, at least one outlet element is designed as an outlet nozzle. Advantageously, this outlet element is at least slightly spaced away from the inner wall of the container. Advantageously, the at least one outlet element is oriented such that the cleaning fluid impacts the inner wall of the receiving container without significant splashing.

[0024] In a further advantageous embodiment, at least one outlet element projects into the receiving container. This outlet element preferably has a cleaning fluid channel that extends substantially tangentially to the receiving container. Advantageously, however, the cleaning fluid exits the outlet element while still inside the receiving container. Preferably, the fluid exits in a horizontal direction.

[0025] In a further advantageous embodiment, the cleaning agent channel that supplies the cleaning agent to the outlet elements is designed, at least in sections, as an annular channel. In this way, the cleaning agent can be guided, for example, via a laterally arranged cleaning agent channel and then, from there, via an annular channel to at least one outlet element, and preferably to both outlet elements. This allows for uniform distribution of the cleaning agent to different areas of the receiving container.

[0026] In a further advantageous embodiment, the valve for supplying the liquid to the tanks also has a closing piston. This closing piston can be designed as described in WO 2014 / 005 951 A1.

[0027] The present invention further relates to a device for filling tanks from a canister, comprising a first adapter device which is suitable and intended for at least temporary attachment to the canisters and which has a feed device through which a flowable medium can be directed from the canister into the tank. Furthermore, the device has a connection for a cleaning agent in order to supply a cleaning fluid to at least one component of the device.

[0028] According to the invention, the device comprises a further receiving container for temporarily receiving the flowable medium to be filled into the tank, and preferably a venting device for venting and / or de-venting this receiving container. This design particularly addresses the fact that transferring the liquid from this receiving container into the tank could potentially create an undesirable negative pressure. Therefore, the venting device preferably serves to vent the receiving container.

[0029] The present invention further relates to a device for filling tanks from a canister, which has a first adapter device which is suitable and intended for at least temporary attachment to the canister and which has a feed device through which a flowable medium can be directed from the canister into the tank, wherein the device has a rinsing agent connection in order to supply at least one component of the device with a cleaning fluid.

[0030] According to the invention, the device has a further receiving container for temporarily receiving the flowable medium to be filled into the tank, as well as a drainage device to drain excess medium.

[0031] In this embodiment according to the invention, it is preferably proposed that a protective mechanism be provided which comes into effect if, for example, too much medium is supplied during a filling process. In particular, it is conceivable that excess liquid, and especially excess water, is drained away in the event of overpressure. Preferably, this draining device serves to remove excess medium, and especially excess liquid medium, from the device.

[0032] In an advantageous embodiment, this draining device comprises a first valve assembly which is suitable and designed to cause a liquid medium to drain from the device by opening (this valve assembly). It is conceivable that this valve assembly is closed in a normal state, but opens if overpressure occurs, thereby draining the liquid medium from the device.

[0033] Preferably, this first valve assembly is designed as a check valve. This means that above a certain overpressure, this valve assembly opens and allows excess fluid to be discharged.

[0034] Particularly preferred is a valve position of this first valve assembly that can be changed by an overpressure generated in the receiving container and / or the filling canister. This first valve assembly can be triggered pneumatically, i.e., by air pressure, or hydraulically, i.e., by fluid pressure. In particular, the first valve can be moved from a closed to an open position by the overpressure. Under normal conditions, this first valve is preferably closed. This means that no fluid is discharged through this valve during normal operation.

[0035] The procedure described here limits the internal pressure in the receiving container or measuring cup, preventing damage to either the receiving element or the canister. In a further advantageous embodiment, a hose connection is provided for draining liquid, particularly water. This allows a hose to be connected to the device, enabling water to be directed precisely to a desired area.

[0036] This first valve, which is preferably designed as a pressure relief valve, opens at a specific pressure and limits the internal pressure, thus preventing damage. If the receiving container is completely or partially filled with liquid medium and overpressure occurs, contaminated liquid may also flow out. Therefore, it is preferred that a hose system or overflow hose leads without resistance to another device, such as a sprayer, a hopper, or a container.

[0037] In a further advantageous embodiment, the said drain assembly has a second valve assembly. Preferably, this second valve assembly is another check valve, which serves in particular, but not exclusively, to prevent pulsation of fluid in the drain line. This second valve assembly is preferably arranged in a section of the drain assembly. In a further preferred embodiment, the device has a hose adapter.

[0038] In another advantageous embodiment, the ventilation device has a valve device which controls an airflow between the receiving container and the environment.

[0039] This valve device can be set in such a way that ventilation only occurs above a certain negative pressure in the receiving container.

[0040] In a further advantageous embodiment, this valve assembly is designed as a check valve. Advantageously, this valve assembly can have a spring-loaded valve body that forces the valve into a closed position. This valve body can be arranged such that, above a certain negative pressure, air can enter the receiving container, but no air or overpressure can be discharged via this valve assembly.

[0041] Therefore, this valve only opens advantageously above a certain negative pressure.

[0042] Advantageously, the valve body in question is movable in a longitudinal direction, whereby this longitudinal direction is in particular also a longitudinal direction of the receiving container or a main flow direction of the liquid to be filled into the tank. In particular, this is a vertical or substantially vertical direction.

[0043] In a further advantageous embodiment, the ventilation device allows air to be supplied to the receiving container and prevents air from being extracted from the receiving container. In a further advantageous embodiment, the valve housing is made of a plastic.

[0044] Particularly preferably, the ventilation device and / or a valve device of the ventilation device is arranged laterally on a support of the device. In a further advantageous embodiment, the ventilation device has at least one air duct that extends in a straight line, at least in sections. In particular, this air duct extends through a housing and / or in a radial direction of the device. Here, too, it is possible that this air duct is designed as an annular duct, at least in sections.

[0045] In a further advantageous embodiment, this valve assembly of the venting device is designed as a float valve. It is conceivable that this valve assembly comprises a hollow sphere which is preferably in an open position when the receiving container is empty. In this position, venting is possible. In other words, air can flow freely in, thus preventing the canister from collapsing due to negative pressure.

[0046] In the event of overfilling of the receiving container, the ball floats on the liquid medium and preferably seals against a tight fit. In this case, the medium can no longer escape. However, it is still ensured that excess air can escape. In a further advantageous embodiment, the venting device can also be manually operated and, in particular, closed. To enable the extraction of large containers with the hose adapter, the airflow can additionally be interrupted by pressing a button, for example. In this case, a negative pressure, necessary for extraction, can build up. However, an actuating device is also provided, which causes this recording or button device to open automatically after the negative pressure in the overall system has dissipated.For this purpose, a preloading device such as a spring can be provided, which causes the button and thus the valve to open after the vacuum is released.

[0047] In a further advantageous embodiment, a connecting channel is provided that connects the overflow valve and / or the vent valve to the interior of the receiving container. It is conceivable that the same channel provides both the flow connection between the overflow valve and the flow connection between the vent valve and the interior of the receiving container. Preferably, this connecting channel has a cross-section that is larger than [value missing in original text]. In this way, it is possible to reduce the flow resistance for the air and thus also the maximum achievable negative pressure during extraction. The same applies to the outflowing water in the case of positive pressure.

[0048] Preferably, the two valves mentioned are arranged next to each other on an outside side of the device.

[0049] In a further advantageous embodiment, the device includes a measuring device for determining the quantity of liquid to be filled into the tank. For example, a flow meter could be provided to measure the liquid flow rate. However, it is advantageous if the additional receiving container is designed as a measuring device for determining the quantity of liquid to be filled into the tank, or if this receiving container itself includes such a measuring device. For example, this receiving container could be transparent and have a scale on one wall for measuring the liquid or its quantity.

[0050] The present invention further relates to a device for filling tanks from a canister, which has a first adapter device suitable for at least temporary attachment to the canister and which has a feed device through which a flowable medium can be directed from the canister into the tank. The device also has a cleaning agent connection for supplying a cleaning fluid to at least one component of the device.

[0051] According to the invention, the device comprises a further receiving container for temporarily receiving the flowable medium to be filled into the tank, and the device comprises a measuring device which is suitable and intended for the quantitative determination of the quantity of liquid to be filled into the tank. Furthermore, the device additionally comprises a display device by means of which at least one spatial position of at least one component of the device can be determined and, in particular, read. In this embodiment of the invention, it is therefore proposed that not only the quantity to be filled can be determined, but also the position of at least one component of the device, and in particular of the receiving container.This takes into account the fact that filling often occurs under conditions where the receiving container is not upright, thus distorting the measurement results. The additional display device ensures that a safe and realistic reading of the measuring instrument is possible.

[0052] Preferably, the positioning of the device component is a pivot position, and in particular a pivot position in space. Therefore, the respective pivot position of the device can preferably be detected by means of the display device.

[0053] In a preferred embodiment, the receiving container is at least partially and preferably completely transparent. In this case, it is possible to detect the fill level of a substance, and especially a liquid, located inside the receiving container through a wall of the container. Preferably, the measuring device has a measuring scale. This measuring scale is particularly preferably arranged in a transparent area.

[0054] This preferably involves a measuring scale that allows for linear reading.

[0055] In another preferred embodiment, the receiving container expands in one direction, for example, it can increase or widen conically from bottom to top.

[0056] According to the invention, the display device allows the spatial position to be determined with respect to at least two mutually perpendicular pivot axes. In this way, it can be determined in particular whether and, if so, when the receiving container is in a preferred position, for example, exactly vertically aligned.

[0057] In another advantageous embodiment, the display device is arranged on a horizontally oriented surface of the device during operation. This ensures particularly convenient and reliable reading. For example, the device may have a mounting flange by means of which the receiving container is attached to other components. This mounting flange may have the aforementioned horizontal surface on which the display device is then arranged.

[0058] In a further advantageous embodiment, the display device has a cavity filled with a liquid. Advantageously, this is a sealed cavity. An air bubble or another suitable float element can be located within this cavity.

[0059] In another advantageous embodiment, the indicator device is a so-called spirit level. Preferably, this spirit level is movable not only along one direction, but preferably within a plane, so that, as mentioned above, a pivot position with respect to two mutually perpendicular pivot axes can be determined. In this way, alignment with respect to two axes can be achieved in a particularly simple manner using the spirit level.

[0060] In a further advantageous embodiment, the measuring device has a readable measuring scale. Advantageously, the display device is arranged such that the display device and the readable measuring scale can be observed simultaneously.

[0061] In a further advantageous embodiment, the device includes a cleaning unit for cleaning this receiving container, which preferably has at least one cleaning fluid channel that allows the cleaning fluid to flow from the cleaning fluid connection to the receiving container. In this way, it is possible to clean the receiving container in a particularly simple manner.

[0062] In a further advantageous embodiment, the cleaning device has at least one outlet element which is oriented such that cleaning fluid exiting from this outlet element reaches an inner wall of the receiving container.

[0063] The display device mentioned above is therefore primarily, but not exclusively, intended to reduce dosing errors that may occur due to an improper positioning of the receiving container or cup.

[0064] In another advantageous embodiment, the receiving container has a funnel-shaped section. In yet another advantageous embodiment, a further valve assembly can also be arranged between the receiving container and the tank. In this way, the receiving container can first be filled with a specific quantity of liquid, and then this quantity can be drained into the tank. This ensures that only a precisely defined quantity of liquid enters the tank. This can be particularly helpful when several liquids are to be mixed together in one tank.

[0065] In another advantageous embodiment, the receiving container has fastening means for attachment to the tank. These may, in particular, be a thread or the like.

[0066] In a further advantageous embodiment, the additional receiving container is made of a plastic. Advantageously, the receiving container allows for the storage of a larger volume of liquid than other parts of the device and, in particular, than other lines leading from the canister adapter to the receiving container. As mentioned above, the additional receiving container is preferably rotationally symmetrical.

[0067] In a further advantageous embodiment, the receiving container is arranged downstream of the feed device in the direction of flow of the liquid being filled into the tank. This means that the liquid from the tank first passes through the adapter devices into the receiving container and can then be drained from there into a tank.

[0068] In a further advantageous embodiment, the device has a valve assembly arranged between the receiving container and the tank to be filled. This valve assembly can be directly connected to the receiving container. Preferably, this valve assembly is manually operated. With the valve assembly closed, the receiving container can be filled with liquid, and the quantity of liquid added can be determined, for example, using the scale shown above. The valve assembly can then be opened to allow the measured liquid to flow into the tank. A channel for directing the liquid can also be connected to this valve assembly.

[0069] Advantageously, the receiving container is also arranged downstream of the flushing connection. Particularly preferably, the receiving container has a circumferential rim, especially a circumferential rim with which it can be flanged to an adapter element.

[0070] In a further advantageous embodiment, sealing devices, such as O-rings or the like, can be provided between the coupling elements. For example, a sealing element can be arranged on the first or second coupling part.

[0071] In a further advantageous embodiment, a valve element, and in particular a closing piston, is arranged in the adapter device which serves to be attached to the canister. This closing piston is preferably adjustable between an open position and a closed position via an actuating element. This closing piston can have an inner channel which, in the open position of the device, provides a second fluid connection, for example, between the rinsing port and the canister mounting port. In addition, this canister adapter can have an outer channel arranged around this closing piston, which, in the open position, establishes part of a fluid connection between the canister and the tank or between the canister and the other receiving container.

[0072] According to a further embodiment of the invention, the first and second coupling parts are designed such that, in the open position of the device, they provide a first fluid connection between the canister mounting flange and the tank mounting flange and a second, lockable fluid connection between the flushing connection and the canister mounting flange.

[0073] For a fluid-tight connection between the tank adapter and the canister adapter, at least one sealing element can be provided on the first or second coupling part. According to a further embodiment of the invention, a closing piston is guided in the canister adapter, which is adjustable between the open and closed positions via an actuating element. This closing piston can have an inner channel which, in the open position of the device, provides the second fluid connection between the flushing port and the canister mounting flange. Furthermore, the canister adapter can have an outer channel arranged around the closing piston which, in the open position, forms part of the first fluid connection between the canister mounting flange and the tank mounting flange.

[0074] Furthermore, the closing piston can have a first contact surface which is in operative contact with a second contact surface provided on the tank adapter when the second coupling part of the canister adapter is coupled to the first coupling part of the tank adapter. According to a preferred embodiment of the invention, the inner channel of the closing piston opens at one end into the first contact surface and is connected at its other end to the canister mounting flange, and the tank adapter has a closable connecting channel which opens at one end into the second contact surface and is connected at its other end to the rinsing port, wherein the connecting channel opening into the second contact surface and the inner channel of the closing piston opening into the first contact surface are connected to each other when the tank adapter and the canister adapter are in contact with each other via the two contact surfaces.It is advisable to provide at least one seal between the two contact surfaces.

[0075] According to a further embodiment of the invention, the closing piston is guided in a cam guide on the canister adapter, wherein a rotation of the canister adapter causes a displacement of the closing piston relative to the canister adapter. Furthermore, it can be provided that the second coupling part of the tank adapter is rotatably mounted on the tank adapter by means of an actuating element. In a further embodiment, the first contact surface of the closing piston is in rotationally fixed contact with the second contact surface on the tank adapter when the second coupling part of the canister adapter is coupled to the first coupling part of the tank adapter (i.e., the second adapter assembly), wherein a subsequent rotation of the second coupling part relative to the tank adapter causes a displacement of the closing piston relative to the canister adapter (i.e., the first adapter assembly).

[0076] Furthermore, it is advantageously provided that the first contact surface of the closing piston is in contact with the second contact surface on the tank adapter when the second coupling part of the canister adapter is coupled to the first coupling part of the tank adapter, and wherein the second contact surface is slidably mounted on the tank adapter in the direction of movement of the closing piston, and a spring element presses the second contact surface against the first contact surface. The displacement or lifting of the second contact surface from the first contact surface can be effected by a further actuating element while the second coupling part of the canister adapter is coupled to the first coupling part of the tank adapter. In this way, additional rinsing or cleaning of the two contact surfaces with a cleaning fluid supplied via the rinsing port is possible.

[0077] Canisters, especially those containing pesticides, are sealed with a foil seal at the outlet before first use. Often, these seals are removed manually by the user, which can easily lead to skin contact with the fluid or a protective glove. In a preferred embodiment of the invention, the canister adapter is therefore provided with an integrated foil cutting element in the area of ​​the canister mounting flange for cutting the canister's foil seal. The foil cutting element can be formed by a toothed ring, which is particularly inclined to the longitudinal center axis of the canister adapter. Furthermore, the canister adapter can have a sliding sleeve to which the canister mounting flange is attached, the sliding sleeve being axially displaceable relative to the foil cutting element.

[0078] Thanks to the integrated foil cutter, the user does not need to remove the sealing film themselves, but simply screws the canister adapter onto the canister's outlet opening using the mounting flange. Either the sealing film is automatically cut during this screwing process, or the opening occurs only after screwing on the adapter, when the foil cutter is brought into contact with the sealing film using the sliding sleeve.

[0079] The present invention further relates to a device for filling tanks from a canister. This device comprises a first adapter assembly suitable for at least temporary attachment to the canister and which includes a feed device through which a flowable medium can be directed from the canister into the tank. The device also includes a connection for a cleaning agent to supply at least one component of the device with a cleaning fluid.

[0080] According to the invention, the device has a further receiving container for temporarily receiving the flowable medium to be filled into the tank, and furthermore the device has a cleaning device for cleaning this receiving container, as well as at least one outlet element that supplies a rinsing medium to the receiving container. In this embodiment, it is therefore proposed that cleaning of said receiving container is also specifically possible.

[0081] In a preferred embodiment, this application device is connected to the cleaning agent inlet via a connecting line. This connecting line can branch off from the cleaning agent inlet. For example, a tea-shaped connector or a hose connector can be provided, allowing the connecting line to branch off from the cleaning agent inlet. In this way, a cleaning medium can be supplied directly above the cleaning agent inlet to clean the receiving container.

[0082] In a further advantageous embodiment, the outlet element is arranged such that cleaning fluid exiting from this outlet element reaches an inner wall of the receiving container.

[0083] In another advantageous embodiment, the outlet element is arranged in such a way that the liquid exiting from it creates a vortex within the receiving container.

[0084] It is generally recommended that the system be cleaned after the liquid medium has been measured. It is also possible, and preferably preferred, to clean the canister, particularly via a canister adapter. For cleaning the receiving container, rinsing nozzles are preferably provided, which, as mentioned above, can be mounted, for example, below the flanges. Preferably, these nozzles, due to their specific arrangement, generate a vortex that cleans the receiving container within a short time.

[0085] In a further advantageous embodiment, the outlet element has a predetermined flow cross-section, which is selected such that, at least during the cleaning process, more liquid flows into the receiving container than cleaning fluid flows out. In other words, the cross-section of these spray elements or nozzles is designed such that more water flows into the cup than can flow out. In this way, the aforementioned vortex builds up even as far as the tank adapter mentioned above. This makes it possible, in particular, to clean the entire receiving container and also a predetermined area, or especially a lower part of the tank adapter.

[0086] A channel can be provided to supply the aforementioned spray elements or flushing nozzles, and this channel is located, in particular, in the connecting flange. This channel can also be connected to the tank flange. In this way, fresh water can be branched off from the flushing connection of the tank flange and directed downwards into the receiving container.

[0087] In a further advantageous embodiment, the connecting line therefore runs at least partially through a mounting flange that serves to attach the feed device to the receiving container. Advantageously, this connecting line runs through both of the aforementioned connecting flanges.

[0088] In a further advantageous embodiment, said connecting line runs straight and particularly preferably in a vertical direction through the connecting flange.

[0089] In a further advantageous embodiment, the device has at least two outlet elements for cleaning the receiving container.

[0090] As mentioned above, these two outlet elements can be arranged at an angle of 180° to each other in the circumferential direction of the receiving container. Advantageously, these two outlet elements generate a vortex, with the output jets of this vortex being offset by 180° to each other.

[0091] In a further advantageous embodiment, the device has at least one annular channel for supplying at least one outlet element with liquid. In particular, the cleaning agent is a detergent. In a further advantageous embodiment, the two outlet elements are identical.

[0092] In a further advantageous embodiment, which can be combined with all of the aforementioned configurations but can also be claimed independently, the receiving container has a support ring to which it is attached. This support ring can have fastening elements to facilitate its assembly. For example, two or more fastening lugs can be provided on the outer circumference of this support ring to enable fastening. Advantageously, three such fastening elements are provided, which are distributed evenly around the circumference of the flange.

[0093] In a further advantageous embodiment, the device has a mounting device that allows the user to attach the device to another device, such as a spray gun. This mounting device can also be combined with the embodiments mentioned above. However, the applicant also reserves the right to claim protection for a device for filling tanks from a canister, comprising a first adapter device suitable for at least temporary attachment to the canister and a feed device through which a flowable medium can be directed from the canister into the tank. This device also has a rinsing fluid connection for supplying a cleaning fluid to at least one component of the device.

[0094] According to the invention, the device here comprises a holding device for attaching it to another element, such as, in particular but not exclusively, a spray gun. Preferably, the device here comprises a receiving container, and the holding device thus also serves to attach this receiving container to another device. In a preferred embodiment, this holding device is arranged in an area in which the receiving container is also located. For example, the holding device can be designed such that it encompasses the receiving container from above and below. Advantageously, this holding device can also form a receiving space that can accommodate at least one component of the receiving container in its circumferential direction.It is possible that the holding device has a ring-shaped section through which at least one component of the receiving container or another component of the device projects.

[0095] In a further advantageous embodiment, the holding device has a mounting section that allows for highly variable attachment of this holding device to another apparatus. For example, this mounting section can have a large number of elongated holes to achieve maximum versatility. These numerous mounting options also make it easy to align the system.

[0096] In another advantageous embodiment, the holding device is arranged on the apparatus in such a way that the valves mentioned above are located above the holding device and are thus relatively well protected from mechanical influences.

[0097] In another advantageous embodiment, the holding device also has a fastening element for attachment to a discharge line that leads out of the receiving container.

[0098] Further advantages and embodiments can be seen from the attached drawings:

[0100] The Fig. Figure 1 shows a device 100 for the contamination-free filling of a tank 1 from a canister 10 before the canister is connected to the tank. The device comprises a tank adapter 6 with a tank mounting flange 36 for attachment to the tank 1 and a first coupling part 62, as well as an adapter assembly 2 with a canister mounting flange 23 for attachment to the canister 10 and a second coupling part 41. The canister mounting flange 23 is designed as a union nut that engages with an external thread of an opening in the canister 10. Preferably, two wedge-shaped discs, rotatable relative to each other, are provided for attaching the tank adapter 6 to the tank 1.

[0101] Fig. Figure 2 shows a side view of a device 100 according to the invention without a tank. A detergent connection 21 is also clearly visible. This connection has an external thread 26 for connecting, for example, a detergent hose. Reference numeral 50, in its entirety, designates a ventilation device for venting, in particular, the receiving container 8. Reference numeral 82 designates a mounting flange with which the receiving container 8 can be screwed to the device by means of mounting screws 84. Reference numeral 32 designates a handle element with which the connection between the coupling parts 41 and 62 can be established or disconnected. Reference numeral 20 designates the cleaning device in its entirety.

[0102] Fig. Figure 3 shows a further representation of the device 100 according to the invention. It can be seen that the receiving container 8 has a measuring scale 86. This can be used to determine the amount of liquid in the receiving container 8.

[0103] Reference numeral 88 indicates a thread with which, for example, another valve element can be connected below the receiving container. This valve element allows the quantity of the liquid in the receiving container 8 to be determined.

[0104] The Fig. 4a and Fig. Figure 4b shows two perspective views of a device according to the invention. It can be seen that the receiving container 8 has a funnel- or cone-shaped lower section 8a.

[0105] Fig. Figure 5 shows a sectional view of the device according to the invention. It can be seen that the canister mounting flange 23 itself is attached to a pipe 25 and engages behind it. In addition, a circumferential sealing element such as an O-ring can be provided, which creates a fluid seal. Reference numeral 66 refers to a valve assembly, which serves in particular for the rinsing process. A flowing rinsing fluid from bottom to top pushes the valve or the valve ball 64 upwards, thus opening the rinsing valve. For this purpose, for example, a pressurized water line can be connected to the rinsing fluid connection 21 (see Figure 5). Fig. 2) be connected, which serves to rinse the device.

[0106] The second coupling part 41 has an octagonal outer cross-section, which is complementary to the first coupling part 62. When the two adapters are connected, the second coupling part 41 is inserted into the first coupling part 62.

[0107] The handle element 32, designed here as a locking bar, serves to fix and lock the second coupling part in the first coupling part 62 by pulling it in the direction of arrow P to the right. The handle element 32 is designed to be approximately U-shaped, with the two legs preferably being cranked inwards in the front leg areas compared to the remaining leg areas.

[0108] To insert the canister adapter into the tank adapter, the actuating element, with its leg sections, is located in the area of ​​the first coupling part 62, allowing the canister adapter to be inserted. By pulling the handle element 32 in the direction of arrow P, the leg sections of the actuating element are moved into the area of ​​the first coupling part and engage with grooves formed by the canister adapter. To release the two adapters, the actuating element is pushed into the tank adapter in the direction of arrow P1, so that the leg sections release the canister adapter. Reference numeral 403 indicates a sealing element located above the aforementioned leg sections, which, in a coupled state, enables a seal between the two coupling parts.

[0109] For cleaning purposes, a first shut-off element 312, designed as a ball valve, and the aforementioned second shut-off element in the form of a valve ball 64 are provided in the flow path of the cleaning fluid in the area of ​​the connecting channel 311. The first shut-off element is opened via an actuating pin 313 connected to the sliding sleeve 306 when the sliding sleeve 306 is moved in its position. The first shut-off element 312 closes according to Fig. 5. The escape of cleaning fluid is reliably prevented even when the cleaning fluid is pressurized, as the pressure of the cleaning fluid pushes the shut-off element 312 into its closed position. Furthermore, the shut-off element is pushed into the closed position by a spring element 314. This ensures that the flushing line remains closed when the shut-off element is in the closed position according to Fig. 5. If pressure is not maintained, a small bore 316 is provided through which any cleaning fluid that may be present can flow into the tank.

[0110] Regarding the details of the cleaning process as well as the filling process of tanks, reference is made to the aforementioned WO 2014 / 005 951 A1, and in particular to the description on page 5, paragraph 3 to page 7, paragraph 1. In this respect, the subject matter of this publication is also made the subject matter of the present disclosure.

[0111] Reference numerals 22 and 24 designate two outlet elements in the form of cleaning nozzles, which project into the receiving container 8 and serve to clean the receiving container 8. The cleaning fluid emerging from these outlet elements 22 and 24 flows down the inner wall of the receiving container in a spiral pattern, as shown by the solid line L.

[0112] Fig. 5a shows another representation of the in Fig. The device shown in Figure 5 depicts a valve assembly 90 located below the receiving container 8. The container can be filled with a liquid to be measured using the valve assembly. After opening the valve assembly, the measured liquid will flow via line 92 and along arrow P3 into the tank (not shown).

[0113] Fig. 6a shows a detailed representation of the in Fig. The device shown in Figure 5, where the flow path of a rinsing agent is indicated by the two arrows P4, shows in particular an annular channel section 94, which distributes the rinsing fluid to the two outlet elements 22 and 24.

[0114] Fig. 6b shows a view from below of the in Fig. The device shown in Figure 6a. The orientation of the two outlet elements 22 and 24 is particularly evident here, which is such that the rinsing agent exits along arrows P5 in a direction that is slightly oblique to the tangential direction of the receiving container 8.

[0115] Fig. Figure 7a shows the complete flow of the rinsing agent when liquid is supplied via the rinsing agent connection 21 and the channel 28.

[0116] The liquid exits upwards along arrow P6 and the shut-off element 312, while on the other hand it is distributed via a ring channel (along the dotted line) to the two outlet elements. Fig. Figure 7b shows the flow of cleaning agent exiting outlet elements 22 and 24 from below. Reference numeral 29 indicates the branch channel that diverges from channel 28. Thus, the cleaning agent connection 21 initially opens into channel 28, and branch channel 29 then diverges from it.

[0117] Fig. 8a and Fig. Figure 8b illustrates the ventilation of the (not shown) receiving container. Reference numeral 50 refers to the ventilation device. This device has a plurality of openings 56 through which air can be drawn in. Reference numeral 52 denotes a valve body, which is biased upwards, i.e., into a closed position of the valve, by a spring 54. This means that, on the one hand, air cannot escape through the openings 56, as this is prevented by the valve body 52. ​​On the other hand, the valve is only opened when a certain negative pressure is reached in the (not shown) receiving container. The airflow passes through the valve—as shown by the solid line P7—and ultimately into the (not shown) receiving container. For this purpose, the device may have a channel, which here runs horizontally, through which air can flow.

[0118] Fig. Figure 8b shows another illustration of the airflow direction. It can be seen that several flows can occur here, so that the airflow can also enter a circumferential ring channel section 94 (top line) and from there enter the receiving container (not shown) at several points. This procedure allows for comparatively rapid ventilation of the receiving container.

[0119] Fig. Figures 9a and 9b show a further representation of the device, again illustrating the airflow path for ventilating the receiving container. It can be seen that this airflow path runs through a channel located in the circumferential flange on which the cleaning elements are also arranged. It would also be possible for the same channel used for ventilating the outlet elements 22 and 24 to be used for this purpose.

[0120] Fig. Figure 10 shows a top view from below of the device according to the invention. Here again, the flow path of the ventilation air, guided in the annular channel, is shown. The ventilation device 50 is also visible in this illustration.

[0121] Fig. Figure 11 shows a top view of the device according to the invention. Here again, both the detergent connection 21 and the venting device 50 are visible. It can be seen that the venting device 50 is offset by 90° with respect to the detergent channel. The handle element 32 is arranged opposite it with respect to an angle bisector between the venting device 50 and the detergent channel. In this way, it can be ensured that the operation of the handle element is affected as little as possible by the detergent channel and the venting device, and that these cannot be accidentally damaged.

[0122] Fig. Figure 12 shows a further representation of the device 100 according to the invention. In addition to the embodiments shown in the preceding figures, a display device 70 is visible here, which serves to ensure during filling that the device is filled in a correctly positioned state and, in particular, in a vertical state of the receiving container. In this case, the measuring device or the measuring scale 86 will display realistic values. Reference numeral 72 refers to an air bubble arranged within a liquid-filled cavity. In this way, the display device 70 is a so-called spirit level. Reference numeral 122 denotes a valve lever and reference numeral 124 a circumferential wall, which simultaneously forms the flow channel for the liquid to be filled into the canister.

[0123] Reference numeral 138 designates a first flange on which the tank adapter is ultimately mounted, and reference numeral 136 designates a second flange, which also serves, in particular, for mounting the receiving container 8. These two flanges 136 and 138 can be bolted together.

[0124] Reference numeral 126 designates a projection on which an actuating element 150 is arranged. The actuating element 150 forms a so-called overflow valve, which serves to allow liquid to be dispensed if the receiving container 8 becomes overfilled. The more detailed operating principle is described below. Reference numeral 50 designates a venting device or a venting valve, which ensures the proper venting of the receiving container 8.

[0125] Fig. Figure 13 shows a further representation of the device according to the invention. A fastening ring can also be seen below the receiving container, with which the outlet or the valve assembly 90 can be arranged. Reference numeral 122 denotes a valve lever with which an outlet valve can be opened or closed. This valve could, for example, be a ball valve.

[0126] Reference numerals 134 indicate fastening lugs, which can be used in particular for fastening the lower second flange 136.

[0127] Fig. Figure 14 shows a top view of the device according to the invention. The actuating element 150 and the ventilation device 50 are again shown. The spirit level, which is arranged on the top of the flange 138, is also visible here.

[0128] Fig. Figure 15 shows the underside of the flange 138. A circumferential channel 162, which supplies the outlet elements 22 and 24, is visible. The projection 126 is also visible, as is a wide channel 152, through which a flow connection can be established, for example, between the circumferential channel 162 and the ventilation device 50, but through which fluid exchange with the overflow valve or actuating element 150 is also possible. The overflow valve can also be actuated by air pressure, with the air again being guided through this channel 152. Reference numeral 154 denotes support ribs that support the aforementioned channel. Preferably, both the overflow valve and the ventilation device 50 can be actuated by air pressure. Reference numeral 135 denotes a circumferential edge of the flange 138.It can be seen that it has cavities and support elements, and is thus designed to be both lightweight and very stable.

[0129] Fig. Figure 16 shows a side view of the device according to the invention, in particular in the area of ​​the flanges 136 and 138 and the tank adapter. It can be seen that the actuating element 150 opens into an outlet line 164. Excess fluid can be discharged via this outlet line.

[0130] This refers in particular to liquid that can occur when the receiving container 8 is overfilled.

[0131] Fig. Figure 17 shows a cross-sectional view of the Fig. The device shown in Figure 16 illustrates this. It can be seen that the overflow device, or rather the actuating element 150, has a valve assembly. This valve assembly has a valve body 174, which is pre-tensioned downwards like a spring by means of a pre-tensioning device 172, thus closing the channel 168. When increased atmospheric pressure occurs, this valve can be opened, and excess fluid can be discharged via the channel 168. It can be seen that the outlet line 164 extends through the two flanges 138 and 136.

[0132] The venting device 50 has a valve body 182, which is designed here as a hollow sphere. In a normal system state, the spring 188 presses the sphere downwards, thus holding the valve in an open position. However, it is also possible for this open position to be held by gravity. Reference numeral 184 designates a valve seat. In this position, air can flow in, thus preventing a canister from collapsing due to a vacuum. If the receiving container is overfilled, the sphere floats on the liquid medium flowing from below, thereby closing off the valve seat 184. In this situation, venting is no longer possible, and the medium cannot escape. Additionally, the push button 193 can be used to stop the airflow. In this case, a vacuum, necessary for suction, can build up.After this negative pressure in the overall system is relieved, the button 193 opens automatically for safety reasons due to spring action, i.e. under the influence of spring 188.

[0133] Fig. Figure 18 shows a further representation of the device according to the invention, wherein the device here has a holding device 190, which serves to hold the device, for example, on a spray gun. This holding device 190 has a rear wall or a mounting surface 192 by means of which the holding device can be attached to a device. For flexible arrangement, this mounting section 192 has a plurality of elongated holes, so that attachment is possible, in particular, also on differently designed mounting elements.

[0134] Reference numeral 198 designates a further fastening section, which can be mounted particularly in the area of ​​an outlet of the device. Reference numeral 196 designates a support plate of the holding device, which can be mounted here particularly below the flange 138.

[0135] Fig. Figure 19 shows a view from below of the lower second flange 136. Here again, the two outlet elements 22 and 24 are provided, from which the cleaning medium can exit along arrows P5. As mentioned above, this enables a spiral cleaning of the receiving container (not shown). The two outlet elements 22 and 24 are supplied, as mentioned above, from an annular channel and ultimately also from the cleaning agent connection 21.

[0136] Fig. Figure 20 shows another side view of the device according to the invention. In this view, arrow P6 also illustrates how the cleaning fluid flows from the rinsing agent connection 21 to the outlet elements 22 and 24. For this purpose, a line connection 112 is provided, which also extends through the two flanges 136 and 138. This line connection 112 is particularly straight, i.e., extends in a vertical direction.

[0137] Fig.Figure 21 shows a more detailed illustration of the venting device 50 and the actuating element 150. It can be seen that the actuating element 150 is designed as a push button. When this push button is pressed, the valve body 174 can be pressed against the channel 168, thus closing the valve. Similarly, the push button, which forms part of the venting device, can also be actuated. Actuating this push button opens the venting device, allowing the system to be vented.
