Embodiment Construction
[0031] A beverage preparation machine according to the invention is indicated generally by 1 in these figures.
[0032] exist figure 1 In the embodiment shown as an example in , the preparation machine 1 comprises a support structure, generally indicated at 3 . The support structure comprises two profiled plates 4 extending on respective substantially parallel vertical plates facing each other.
[0033] In order to make the kinematic mechanism of the preparation machine 1 visible, in figure 1 The profiled plate 4 closer to the viewer is shown in dotted outline.
[0034] A hot water dispensing head of known type, shown generally at 5, is mounted in a fixed position between the like ends of a pair of plates 4. In the shown embodiment, the dispensing head 5 is mounted in a vertically inclined posture, but it does not have to be so arranged.
[0035] The dispensing head 5 is also connected in a known manner to heating equipment not shown, such as a kettle or a heat exchanger. ...

The machine (1) comprises: a support structure (3) carrying a hot-water dispensing head (5), a capsule-carrying assembly (6), mounted so as to be movable in a first plane in the support structure (3), guide means (9-12) suitable for allowing the capsule-carrying assembly (6) to move between a working position in which the assembly is coupled with the dispensing head (5) and an intermediate position in which the assembly (6) can pivot about a first axis (B-B) perpendicular to the first plane, towards an angular loading position in which it can receive a capsule (2), and an actuating device (14-19) including: an actuator member (14) which is rotatable about a second fixed axis (A-A), parallel to the first axis (B-B), is coupled with the capsule-carrying assembly (6), and can bring about the movement thereof between the working position and the loading position; ; and at least one arm (16) which is controlled by the actuator member (14) and is provided with a revolving roller (17) which is engaged in a corresponding rolling guide (18) of the capsule-carrying assembly (6), and which is arranged in a second plane parallel to said first plane. The arrangement is such that, when the capsule- carrying assembly (6) is situated between the loading position and the intermediate position, its movement is controlled by means of the revolving roller (17) of the at least one arm (16) and the corresponding guide (18) and, when the capsule-carrying assembly (6) is in a position between the intermediate position and the working position the revolving roller (17) can disengage from the corresponding guide (18) and the at least one arm (16) is coupled directly with the capsule- carrying assembly (6); so that the latter can be urged towards and against the dispensing head (5) directly by the arm (16).
Description
technical field [0001] The present invention relates to a coffee machine for preparing beverages, in particular coffee, by infusing the substance contained in a capsule or such a container. Background technique [0002] In this specification and in the appended claims, the term "capsule" generally means a packet containing a portion of a product, such as ground charcoal coffee, suitable for preparing a beverage by infusion or percolation. [0003] In this sense, therefore, the term "sack" also means, for example, so-called filter paper "bags" or such containers. [0004] The previous European patent application EP-1854384A1 describes and depicts a beverage preparation machine in which the movement of the capsule carrying assembly can be controlled by a transmission member which can rotate about an inclined axis parallel, or even coplanar, with the plane of movement of the body. [0005] The drive has a transverse arm on which is provided revolving end rollers engaging prede...
