Abstract

Moreover, the jaws (41), adjacent to said coordinated gripping profiles (50), have respective further coordinated gripping profiles (51) able to cooperate with corresponding predetermined portions of the lateral surface of a capsule (CX) of a further and different type able to be introduced into the machine as well as to splay and pass beyond the inlet portions (41a, 45) of the jaws (41). These further coordinated profiles (51) are shaped and/or arranged such that they are capable of defining, for a capsule (CX) of the further type, a corresponding retaining position in which the capsule (CX) of the further type is axially offset by a predetermined amount (Δ) with respect to the predetermined reference direction (R-R).

First claim

The invention claimed is:

1. A gripper device ( 100 ) for retaining a capsule (C) in a machine ( 1 ) for the preparation of beverages, in particular espresso coffee, comprising
a pair of opposite movable jaws ( 41 ) having respective coordinated gripping profiles ( 50 ) intended to cooperate with corresponding predetermined portions of the lateral surface of the capsule (C) of a first predetermined type so as to define a retaining position for such the capsule (C) in which the capsule (C) is essentially coaxial with a predetermined reference direction (R-R),
said jaws ( 41 ) being able to assume a relative rest or standby position in which they are close to one another and inlet portions thereof ( 41 a , 45 ) are capable of being splayed and passed beyond by the capsule (C) introduced into the machine ( 1 ), so as to allow said capsule (C) to be positioned and gripped between said gripping profiles ( 50 ) in said retaining position;
the device being characterized in that said jaws ( 41 ), adjacent to said coordinated gripping profiles ( 50 ), have respective further coordinated gripping profiles ( 51 ) able to cooperate with corresponding predetermined portions of the lateral surface of a capsule (CX) of a further and different type able to be introduced into the machine ( 1 ) as well as to splay and pass beyond the inlet portions ( 41 a , 45 ) of said jaws ( 41 );
said further coordinated gripping profiles ( 51 ) being shaped or arranged such that they are capable of defining, for the capsule (CX) of said further type, at least one corresponding retaining position in which the capsule (CX) of said further type is axially offset with respect to said predetermined reference direction (R-R).

2. The gripper retention device according to claim 1 , wherein each jaw ( 41 ) has a gripping profile ( 50 ) and the further coordinated gripping profile ( 51 ) which are staggered with respect to one another at least along said predetermined reference direction (R-R).

3. The gripper retention device according to claim 2 , wherein in each jaw ( 41 ) the gripping profile ( 50 ) and the further coordinated gripping profile ( 51 ) are integral with each other.

4. The gripper retention device according to claim 2 , wherein in each jaw ( 41 ) the gripping profile ( 50 ) and the further gripping profile ( 51 ) are provided on portions ( 41 d ; 41 c ) of the jaw ( 41 ) which are movable relative to one another.
