Abstract

A device for the automatic ejection of a capsule or pellet in a machine for the production of hot beverages or coffee, where the machine comprises a movable part (13), moved by an actuator (14), and a fixed part (15), realising an infusion chamber (20) where the capsule or pellet (16) is placed, an extractor element (28) being foreseen, in the device the extractor element (28) being associated with a sliding element (21), provided at an upper end with an ejection plate (30) shaped to be arranged, in rest position, partially around the seat (20), transversally to the movement between the fixed part and the movable part, the sliding element (21) being movable through axial and rotation movement seat (20), the axial and rotation movement between a rest position and a raised position in which the rotating plate (30) removes a capsule placed in the determined by elements of mutual engagement (18, 19; 29), one arranged on the movable part (13) and the other on the sliding element (21), which may be disengaged in the raised and rotated position.

Claims

1. Device for the automatic ejection of a capsule or pellet in a machine for the production of hot beverages or coffee, where said machine comprises a movable part (13), moved by means of an actuator (14), and a fixed part (15), which realise an infusion chamber (20) between them where a beverage or coffee capsule or pellet (16) is placed, a movable extractor element (28) being foreseen within said infusion chamber, the device being characterised in that associated with said extractor element (28) is a sliding element (21), provided at an upper end with an ejection plate (30) shaped to be arranged, in rest position, partially around said seat (20) of the capsule or pellet (16), transversally to the movement between said fixed part (15) and said movable part (13), the sliding element (21) being movable through axial and rotation movement between a rest position and a raised position in which said rotating plate (30) removes a capsule arranged in said seat (20), said axial and rotation movement being determined by mutual engagement elements (18, 19;

29), one arranged on said movable part (13) and the other on said sliding element (21), which may be disengaged in the raised and rotated position.

2. Device according to claim 1, characterised in that said sliding element (21) is a bush, arranged sliding on a column (12) of the frame of said machine.

3. Device according to claim 1, characterised in that said sliding element (21) extends into a connection plate (27) which constrains the sliding extractor element (28) within said fixed part (15).

4. Device according to claim 1, characterised in that said sliding element (21) is a bush which foresees a shaped slot (25) on one of its outer side surfaces, in which a freely sliding guide pin (26) is positioned, integral with said fixed part (15), said shaped slot (25) determining said axial and rotation movement.

5. Device according to claim 1, characterised in that said sliding element (21) is maintained in said rest position by a contrast spring (22).

6. Device according to claim 1, characterised in that said elements of mutual engagement comprise a hooking element (18) with curved free end (19) on one side, arranged on the movable part (13), and a rigid hooking tooth (29) on the other side, arranged on said sliding element (21).

7. Device according to claim 6, characterised in that said rigid hooking tooth (29) extends radially outward for a limited section of circumference of said sliding element (21).

8. Device according to claim 6, characterised in that said hooking element (18) arranged on said movable part (13) is of flexible type.

9. Device according to claim 1, characterised in that said actuator (14) is of any type, such as electromechanical, hydraulic, pneumatic, manual or other.

10. Device for the automatic ejection of a capsule or pellet in a machine for the production of hot beverages or coffee essentially as described above and as illustrated in the attached drawings.
