The invention relates to an apparatus for emptying a fluid container, wherein the apparatus comprises a pumping unit configured to pump fluids, and a display device.
The invention further relates to a corresponding method for coupling a fluid container to an apparatus for emptying said fluid container.
The above mentioned apparatus for emptying a fluid container is known, e.g., as an apparatus for fluid delivery from said fluid container. Some of these apparatuses comprise controller modules with display devices for displaying additional information concerning the pumping unit like rotational speed, working hours, etc.
When exchanging the empty fluid container, it is necessary to ensure that the new fluid container contains the desired fluid. In some systems this is realized by a fluid type specific coupling system for coupling the fluid container to the apparatus. These kinds of coupling systems sometimes are undesired for various reasons.
Therefore, the object underlying the present invention is to provide alternative measures ensuring that the newly coupled fluid container contains the desired fluid.
This object is achieved by the invention as defined by the independent claims. The dependent claims detail advantageous embodiments of the invention.
According to various aspects of the invention, the apparatus for emptying a fluid container comprises: (i) a pumping unit configured to pump fluids; (ii) a display device; (iii) a data input unit comprising a read-out device configured to read out fluid type identifying data from at least one marking element of the fluid container automatically and/or input means configured for a manual input of said fluid type identifying data and/or for choosing these fluid type identifying data from a list of reference data displayed on the display device; (iv) an identification unit configured to perform a data comparison of the fluid type identifying data with the reference data for identifying the fluid inside the fluid container. The apparatus is configured to display fluid type information about the identified fluid type of the fluid in the fluid container on the display device. The displayed fluid type information enables the user to check at a glance, which type of fluid is provided by the fluid container coupled to that apparatus. The fluid type identifying data can be part of the displayed fluid type information.
The marking element contains the fluid type identifying data for identifying the fluid inside the container or—to be more generally—the fluid the container is intended for. The marking element can be a marking label on the outer shell of the fluid container. The fluid can be any kind of liquid, aerosol, etc. Preferably, the fluid is an industrial manufactured product for disinfection and/or cleaning in liquid form.
According to a preferred embodiment of the present invention, the apparatus is configured to await a manual confirmation entry via the input means in order to start the emptying process. In other words, the user of the apparatus has to confirm the fluid type information displayed on the display device of the apparatus manually.
In accordance with another aspect of the present invention, the identification unit is configured to perform a data comparison of the current data input of fluid type identifying data with the fluid type identifying data of the fluid container previously coupled to the apparatus. In addition to the storage of the reference data list, the apparatus stores the fluid type identifying data of the fluid container previously coupled to the apparatus. The apparatus is preferably configured to release a signal in case the currently identified fluid type differs from the fluid type of the fluid in the fluid container previously coupled to the apparatus. According to another preferred embodiment of the present invention, the read-out device is a bar code scanner or a QR code scanner (QR: quick response) or a scanner for OCR (Optical Character Recognition) or an RFID chip reader (RFID: radio-frequency identification). The corresponding marking element of the fluid container is a bar code label, a QR code label or a graphic character label or an RFID chip.

Additional details, features, characteristics and advantages of the object of the invention are disclosed in the figures and the following description of the respective figures, which—in exemplary fashion—show one embodiment and an example of a dispensing system according to the invention. In the drawings:
The illustration in
The apparatus 12 further comprises an identification unit provided by the data processor and a data storage device (not shown) of the controller unit 21. The identification unit is configured to perform a data comparison of the fluid type identifying data with the reference data listed in the list. The controller unit 21 is configured to display the fluid type information about the identified fluid type (of the fluid in the fluid container 10) on the display device 22. The apparatus 12 is configured to await a manual confirmation entry via the input means 24 in order to start the emptying process.
Further on, the apparatus 12 is configured to check whether the pumping unit 20 is qualified for pumping the fluid encased in the fluid container 10. The apparatus 12 further comprises a suction lance 30 protruding into the fluid container 10.
Coupling a (new) fluid container 10 to the aforementioned apparatus 12 can be performed by the following steps:
The displayed fluid type information enables the user of the apparatus 12 to check “at a glance”, which type of fluid 18 is provided by the fluid container 10 coupled to that apparatus 12.
In an optional confirming step subsequent to the displaying step, the user has to confirm the displayed fluid type information to start the pumping process.
In an optional comparison step, the identification unit performs a data comparison of the current data input of fluid type identifying data with the fluid type identifying data of the fluid container 10 previously coupled to this apparatus 12.
In an optional checking step, the apparatus 10 checks whether the pumping unit 20 is qualified for pumping fluids 18 of the identified fluid type. Afterwards, the pumping process is started automatically, if the pumping unit 20 is qualified for the identified fluid type.
In several embodiments, the apparatus 12 further comprises a sensor module (not shown) configured to measure a filling level of the fluid container 10 when coupled to the fluid container 10. The display device 22 is configured to display the filling level, which results in the following safety levels:
Level 1—visually with fluid type information (e.g. fluid name):
After setup with a fluid container 10 and corresponding fluid type information, display device 22 always shows the fluid type information.
After “empty detection”, the user is informed that he has to replace the fluid container 10 (e.g. barrel) with the marking element 14 comprising the fluid type identifying data which correspond to the fluid type information displayed on the display device 22.
After replacing the fluid container, the user has to confirm at the apparatus 12, that he has carried out the replacement with the right fluid type (comparing the fluid type information/fluid type identifying data visually).
Level 2—visually with i.e. a SmartPhone 34 and fluid type identifying data (e.g. label information)
After setup with a fluid container 10, the display device 22 always shows the corresponding fluid type information.
After “empty detection”, the display device 22 shows beneath the fluid type information additional information like a GTIN-13-Code (QR-Code) corresponding to the adjusted fluid type (the additional information might be the pH value, viscosity arid other relevant parameters stored in the pump).
After replacing the fluid container 10, the user has to scan the fluid type identifying data (e.g. GTIN-13-Code or QR-Code) of the marking element of the fluid container 10.
Then the user has to scan the fluid type identifying data (e.g. GTIN-13-Code or QR-Code) which is shown on the display. A Mobil App running on the SmartPhone compares the information of both GTIN-13-Code or QR Code and gives “green light” for identical fluid types, “yellow light” for similar fluid types and “red light” for different fluid types. Of course the scan sequence could be vice versa.
Then the user has to confirm manually at the apparatus 12 the replacement of the fluid container 10. Requirement for level 2 is equipment (i.e. a SmartPhone) with adequate software for scanning and comparing.
Level 3—automatically with connected read-out device (26) like, e.g., a scanner:
After setup with a fluid container, the display device 22 always shows the fluid type information (like e.g. the fluid name).
After empty detection, the display device shows beneeth the fluid type information a message that the user has to connect the scanner to the USB port of the apparatus 12.
After replacing the fluid container 12, the user has to read out the marking element 14 (e.g. GTIN-13-Code, QR-Code) printed on the label of the fluid container 12 with the camera).
After transmitting the data from the read-out device 26 to the apparatus 12, the software of the apparatus 12 compares the fluid type identifying data (GTIN-13-Code, QR-Code) with the reference data from the list of reference data and gives green for identical fluids 18, yellow for similar fluids 18 and red for different fluids 18.
When not green, the user he has to confirm manually at the apparatus that the pumping unit has to work with scanned fluid.
It should be noted that, as used in this specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents unless the content clearly dictates otherwise. Thus, for example, reference to a composition containing “a compound” includes a mixture of two or more compounds. It should also be noted that the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise.
