Refill station for a dispenser can with a scale for determining a weight information of the dispenser can at a receiving device
Refill station comprising a receiving device for receiving a dispenser can which is to be refilled with an active substance, a scale for capturing a weight information which is related to the dispenser can at the receiving device prior to a refill process and/or during a refill process, and a control unit which is configured for controlling a refill of the dispenser can with the active substance based on the determined weight information.
1 . Refill station comprising:
a receiving device for receiving a dispenser can which is to be refilled with an active substance, the receiving device comprises a receiving side for receiving the dispenser can and a weighting side which is opposing to the receiving side;
a scale for capturing a weight information which is related to the dispenser can at the receiving device prior to a refill process or during a refill process;
control unit which is configured for controlling a refill of the dispenser can with the active substance based on the captured weight information; and
a supply terminal for supplying the active substance or a pressure gas to the dispenser can,
wherein the scale and the supply terminal are attached at the weighting side.
2 . Refill station according to claim 1 , wherein the scale is arranged below the receiving device, and the dispenser can, in a state received at the receiving device, is arranged in an upright manner.
3 . Refill station according to claim 1 , wherein the scale is arranged above the receiving device, and the dispenser can, in a state received at the receiving device, is arranged upside down.
4 . Refill station according to claim 1 , wherein the scale is a beam scale.
5 . Refill station according to claim 1 , wherein the scale comprises a securing mechanism which provides a protection against an overload of the scale.
6 . Refill station according to claim 5 , wherein the securing mechanism comprises a double leaf spring which is attached to an end of a weighting beam of the scale which is opposing to another end of the weighting beam, wherein the other end, in a state received at the receiving device, is force-coupled with the dispenser can.
7 . Refill station according to claim 1 , wherein the control unit is configured for determining a residual filling of the dispenser can prior to a refill process based on a weight information which is determined by the scale prior to the refill process, and for controlling the refill process based on this weight information.
8 . Refill station according to claim 1 , wherein the control unit is configured for determining the weight information by the scale during a refill process, and for subsequently continuing the refill process based on this weight information.
9 . Refill station according to claim 1 , wherein the control unit is configured for controlling a refill process based on a differential weight determination of the dispenser can which is performed by the scale prior to the refill process and after at least a part of the refill process.
10 . Refill station according to claim 1 , wherein the scale is configured for capturing a weight information which is indicative for a sum weight of the dispenser can, a residual filling of the dispenser can, and a part of the refill station, prior to a refill process or during a refill process.
11 . Refill station according to claim 1 , comprising a transponder reading device for reading dispenser can- related data of a dispenser can transponder which is assigned to the dispenser can;
wherein the control unit is configured for controlling the refill of the dispenser can with the active substance based on the read dispenser can- related data.
12 . Refill station according to claim 11 , wherein the transponder reading device is configured for reading dispenser can-related data which are indicative for an empty weight of the dispenser can, an active substance which is to be filled into the dispenser can, or a maximum filling amount of the dispenser can.
13 . Refill station according to claim 1 , wherein the receiving device comprises a protrusion at the weighting side, to which the scale is attached, and which delimits a recess through which the supply terminal is guided.
14 . Refill arrangement comprising:
a refill station according to claim 1 ; and
a dispenser can which is attachable or attached to the receiving device, wherein, by the scale, a weight information which is related to the dispenser can at the receiving device is capturable, when the dispenser can is attached to the receiving device.
15 . Refill arrangement according to claim 14 , comprising an active substance container which contains an active substance, and which is coupled or couplable with the receiving device, to provide the active substance for refilling the dispenser can.
16 . Refill arrangement according to claim 14 , comprising a gas reservoir which is configured for providing the pressure gas, and which is coupled or couplable with the receiving device, to provide the pressure gas for refilling the dispenser can.
17 . Method for operating a refill station, wherein the method comprises: using the refill station according to claim 1 ;
receiving the dispenser can which is to be refilled with the active substance at the receiving device of the refill station;
capturing the weight information which is related to the dispenser can at the receiving device prior to a refill process or during a refill process by the scale; and
controlling the refill of the dispenser can with the active substance based on the captured weight information.
