Apparatus for filling storage containers on dispensing appliances
View Patent ↗In a device for filling dispensing appliances having a pump unit with a metering cylinder and a storage container for each component, a respective coupling arrangement ( 5 ) is provided between each storage container ( 2, 3 ) and an associated coupling of a filling station. In a preferred embodiment, the appliance coupling part ( 28 ) is arranged in an inlet nozzle ( 17 ) of the dispensing appliance ( 1 ) and the station coupling part ( 29 ) in a guide ( 31 ) in the enclosure ( 33 ) of the filling station ( 30 ). This device allows a quick and simple filling of storage containers without contaminations and air entrapment.
1. A device for filling storage containers on a dispensing appliance having a pump unit and a metering cylinder for each component, the storage containers being connected to the metering cylinders, wherein the device comprises:
a filling station, for receiving the dispensing appliance, that includes a coupling arrangement located between each storage container and an associated coupling of the filling station,
wherein each coupling arrangement includes an appliance coupling part and a station coupling part
wherein the coupling arrangements are arranged on a same axis and opposite each other between the outlets of the storage containers and the inlets of the metering units, and
wherein the appliance coupling part is arranged on an inlet nozzle of the dispensing appliance and the station coupling part is arranged in a guide in a support of the filling station.
2. The device of claim 1 , wherein the station coupling part includes a coupling head that is displaceable with respect to the guide, a sealing cylinder that receives an opening push rod and is displaceable with respect to the coupling head, and a centering portion that is slidable over a centering sleeve on the inlet nozzle of the dispensing appliance.
3. The device of claim 1 , wherein the appliance coupling part comprises a valve head under the action of a first compression spring, wherein an opening push rod in the station coupling part is under the action of a second compression spring, wherein a push rod shaft of the opening push rod is secured in a coupling head, and wherein the coupling head is actuatable by an actuating member.
4. The device of claim 1 , wherein the coupling arrangement comprises sealing means that seal a valve head and an opening push rod against the inlet nozzle.
5. The device of claim 4 , wherein the opening push rod is arranged in a sealing cylinder that is disposed in the coupling head and is sealed against the coupling head by means of a joint.
6. The device of claim 1 , wherein the coupling head comprises a joint arranged in the sealing cylinder that seals the sealing cylinder both against a conical portion of an opening push rod and against the inlet nozzle.
7. The device of claim 1 , wherein the device further comprises two coupling arrangements that are each actuatable by mechanical and/or electric and/or pneumatic and/or hydraulic actuating means.
8. A method for filling storage containers on a dispensing appliance with a device according to claim 1 , wherein the dispensing appliance is introduced in the opened filling station and by actuating quick clamps, both the dispensing appliance is clamped and valves in the appliance coupling part and in the station coupling part are opened, after which, by unlocking and actuating the quick clamps, the valves are closed and the dispensing appliance is released and may be removed.
9. The device of claim 2 , wherein the appliance coupling part comprises a valve head under the action of a first compression spring, wherein the opening push rod in the station coupling part is under the action of a second compression spring, wherein a push rod shaft of the opening push rod is secured in the coupling head, and wherein the coupling head is actuatable by an actuating member.
10. The device of claim 2 , wherein the coupling arrangement comprises sealing means that seal a valve head and the opening push rod against the inlet nozzle.
11. The device of claim 10 , wherein the opening push rod is arranged in a sealing cylinder that is disposed in the coupling head and is sealed against the coupling head by means of a joint.
12. The device of claim 2 , wherein the coupling head comprises a joint arranged in the sealing cylinder that seals the sealing cylinder both against a conical portion of the opening push rod and against the inlet nozzle.
13. The device of claim 2 , wherein the device further comprises two coupling arrangements that are each actuatable by mechanical and/or electric and/or pneumatic and/or hydraulic actuating means.
14. A method for filling storage containers on a dispensing appliance with a device according to claim 2 , wherein the dispensing appliance is introduced in the opened filling station and by actuating quick clamps, both the dispensing appliance is clamped and valves in the appliance coupling part and in the station coupling part are opened, after which, by unlocking and actuating the quick clamps, the valves are closed and the dispensing appliance is released and may be removed.
