Capsule dispensing device
A cartridge dispenser ( 1 ) has: a receptacle ( 10 ) delimiting a cavity ( 10 ′) for storing cartridges ( 2 ); a cartridge outlet ( 11 ) for dispensing a single cartridge at a time from said cartridges ( 2 ), the single cartridge being dispensed in a predetermined cartridge dispensing orientation; and a cartridge transfer device ( 12,13,14 ) for transferring cartridges ( 2 ) from the cavity ( 10 ′) to the cartridge outlet ( 11 ). The cavity ( 10 ′) is so dimensioned that cartridges ( 2 ) can be stored in bulk therein at random capsule orientations. The transfer device comprises a delivery conveyor that is configured to displace cartridges from the bulk of cartridges towards the outlet and to deliver the cartridges ( 2 ) to the outlet ( 11 ) via an orientation-discrimination passage ( 15 ) which ensures that the cartridges ( 2 ) are delivered one at the time to the outlet ( 11 ) and that each cartridge ( 2,2 a ) that is delivered to the outlet ( 11 ) is in the predetermined orientation at the outlet ( 11 ).
1. A cartridge dispenser comprising:
a receptacle defining a cavity for storing cartridges;
a cartridge outlet for dispensing a single cartridge at a time from cartridges in the cavity, the single cartridge being dispensed in a predetermined cartridge dispensing orientation;
a cartridge transfer device for transferring the cartridges from the cavity to the cartridge outlet;
the cavity is so dimensioned that the cartridges can be stored in bulk therein at random cartridge orientations; and
the cartridge transfer device comprises a delivery conveyor that is configured to drive each of the cartridges from the bulk of the cartridges towards the cartridge outlet and to drive each of the cartridges to the cartridge outlet along an orientation-discrimination passage comprising a return conveyor, the orientation-discrimination passage ensures that each of the cartridges are driven one at a time to the cartridge outlet and that each of the cartridges that is driven to the cartridge outlet is in the predetermined cartridge orientation at the cartridge outlet,
wherein the orientation-discrimination passage is configured to:
maintain the random cartridge orientation of the cartridge to be driven to the cartridge outlet when the cartridge to be driven is close to or reaching the orientation-discrimination passage and is in a first position and orientation for being driven to the cartridge outlet in the predetermined cartridge dispensing orientation;
adjust the random cartridge orientation and/or a position of the cartridge to be driven when the cartridge to be driven is close to or reaching the orientation-discrimination passage and is in one or more second position, each offset or tilted relative to the first position; and
reject the cartridge to be driven to the bulk of stored cartridges in the cavity using the return conveyor, the return conveyor configured to move one or more cartridges within the cavity and away from the orientation-discrimination passage when the one or more cartridges are in the one or more second position and when the cartridge to be driven is close to or reaching the orientation-discrimination passage.
2. The cartridge dispenser of claim 1 , wherein the delivery conveyor is associated with a least one delivery guide for guiding the cartridges inside the cavity to the delivery conveyor.
3. The cartridge dispenser of claim 1 , wherein the orientation-discrimination passage is defined by a window that is dimensioned to allow only one cartridge to pass there through at a time.
4. The cartridge dispenser of claim 1 , wherein the delivery conveyor comprises a roll conveyor.
5. The cartridge dispenser of claim 1 , wherein the return conveyor has a part facing a part of the delivery conveyor and configured for moving in opposition thereto.
6. The cartridge dispenser of claim 1 , wherein the return conveyor is associated with a return guide configured to guide one or more cartridges, that have been moved away from the orientation-discrimination passage by the return conveyor, back towards the delivery conveyor.
7. The cartridge dispenser of claim 1 , wherein the return conveyor comprises roll conveyor.
8. The cartridge dispenser of claim 1 , wherein the cartridge outlet has a dispensing opening through which the cartridges are driven or made available to outside the cartridge dispenser in the predetermined cartridge dispensing orientation.
9. The cartridge dispenser of claim 1 , wherein the cartridge outlet has a guide arrangement, along which the cartridges are guided to outside the cartridge dispenser in the predetermined cartridge dispensing orientation.
10. A cartridge dispenser comprising:
a receptacle defining a cavity for storing cartridges, each cartridge comprises a body and a circular annulus flange extending from a peripheral part of the body;
a cartridge outlet for dispensing a single cartridge at a time from cartridges in the cavity, the single cartridge being dispensed in a predetermined cartridge dispensing orientation;
a cartridge transfer device for transferring the cartridges from the cavity to the cartridge outlet;
the cavity is so dimensioned that the cartridges can be stored in bulk therein at random cartridge orientations; and
the cartridge transfer device comprises a delivery conveyor that is configured to drive each of the cartridges from the bulk of the cartridges towards the cartridge outlet and to drive each of the cartridges to the cartridge outlet along an orientation-discrimination passage comprising a return conveyor, the orientation-discrimination passage ensures that each of the cartridges are driven one at a time to the cartridge outlet and that each of the cartridges that is driven to the cartridge outlet is in the predetermined cartridge orientation at the cartridge outlet,
wherein the orientation-discrimination passage is configured to:
maintain the random cartridge orientation of the cartridge to be driven to the cartridge outlet when the cartridge to be driven is close to or reaching the orientation-discrimination passage and is in a first position and orientation for being driven to the cartridge outlet in the predetermined cartridge dispensing orientation;
adjust the random cartridge orientation and/or position of the cartridge to be driven when the cartridge to be driven is close to or reaching the orientation-discrimination passage and is in one or more second position, each offset or tilted relative to the first position; and
reject the cartridge to be driven to the bulk of stored cartridges in the cavity using the return conveyor, the return conveyor configured to move one or more cartridges that are in the one or more second position within the cavity and away from the orientation-discrimination passage when the one or more cartridges are close to or reaching the orientation-discrimination passage.
11. The cartridge dispenser of claim 10 , wherein the cavity for storing cartridges comprises cartridges.
