An infusion group (101) to be used in a machine for dispensing beverages extracted from capsules, in particular coffee, tea, herbal teas and the like, which infusion group comprises: a capsule-holder (1) which defines an infusion chamber (10); an infusion head (2), apt to cooperate with said capsule-holder (1) for the extraction of the beverage; a system (102) for the relative movement of a capsule (C) with respect to the capsule-holder (1), apt to determine a relative translational motion in a direction of infusion (L) which is a direction of approaching/departing the capsule to/from the infusion chamber (10); a retaining device (100) of the capsule during the relative motion between capsule and capsule-holder (1), comprising at least a first (31) and a second (32) oblong element for retaining a projecting upper edge of the capsule, which first and second retaining element develop vertically (V), wherein the first retaining element (31) is configured so as to retain the capsule during a relative motion that carries the capsule to be infused to enter the infusion chamber (10) and the second retaining element (32) is configured so as to retain the capsule during a relative motion for extracting the used capsule from the infusion chamber (20) and to allow the ejection thereof by gravity from the infusion group; and a pair of control arms (41, 42), apt to determine that the relative motion between capsule and capsule-holder (1) is carried out in a coordinated manner with the relative position between capsule-holder (1) and infusion head (2). |

1. A guiding device of a capsule, for use in a machine for dispensing beverages extracted from capsules, in particular coffee, tea, herbal teas and the like, which machine comprises: a capsule-holder which defines an infusion chamber; an infusion head, configured to cooperate with the capsule-holder for an extraction of a beverage; and a moving system determining a relative movement of the capsule with respect to the capsule-holder, which moving system is configured to determine a relative translational motion of approaching and departing of the capsule to and from the infusion chamber in a direction of infusion,which device comprises:
a retainer means of the capsule during said relative translational motion, the retainer comprising at least a first retaining element and a second retaining element for retaining a peripheral projecting edge of the capsule, wherein said first retaining element is configured so as to retain the capsule during a relative motion that carries the capsule to be infused to enter within the infusion chamber and said second retaining element is configured in such a way as to retain the capsule, once used, during a relative movement of extraction of the capsule from the infusion chamber and to allow capsule ejection by gravity from the machine; and a mechanical controller, configured to determine that the relative translational motion between the capsule and the infusion chamber is carried out in a coordinated manner with a relative position between the capsule-holder and the infusion head, wherein said mechanical controller in turn comprises: one or a pair of arms, said one arm or each of said pair of arms being configured to be slidingly coupled with a frame of the machine; a cam engagement profile obtained on said or one of said arms, which cam engagement profile is configured to couple with a corresponding profile of the machine, said coupling causing, in use, a divarication of the device relative to the infusion head; and an engagement element obtained on said arm or on one of said pair of arms, which engagement element is configured to couple with a respective engagement element of the machine so as to allow a selective dragging in translation of the device during a return stroke after infusion. |
