Abstract

A machine readable identification on a single-serving unit containing coffee powder for espresso machines, designed so that it can be read easily and accurately, is structured in a rotation-symmetrical manner and is applied to an essentially level surface of the single-serving unit, whereby the single-serving unit preferably consists of a single-serving capsule (1) having an essentially circular base (2) whereupon the identification is applied in a coaxial manner.

Claims

1. A magazine unit (10) of a coffee machine for storing single serving capsules and processing machine readable identifications disposed on the single serving capsules for election of one of a plurality capsules in a coffee machine comprising:

several magazine tubes (12 to 16), each magazine tube adapted to hold single serving capsules (1) containing various types of coffee powder where the single serving capsules have an essentially circular base (2);

a registration device with at least one reading head (27) adapted to read the identification consisting of concentric circles disposed on the single serving capsules in a linear manner, wherein the reading head (27) is positioned below the magazine tubes (12 to 16) and is directed upwards, toward a plane where the bases of the single serving capsules (1) are located inside the magazine tube (12 to 16) in such a way that identification of single serving capsules can be read in a linear manner,

a carrier wherein the magazine tubes (12 to 16) are located on the carrier and can each be conveyed, as selected, together with the carrier to a dispensing position (18), and that the carrier is provided with transparent sections located below each magazine tube (12 to 16) for scanning the base (2) of the single-serving capsule (1) with the at least one reading head (27), and

a turntable (11) and a Maltese-cross-type drive mechanism (20) wherein the magazine tubes (12 to 16) are arranged in an essentially circular manner on the turntable (11) serving as carrier and that the Maltese-cross-type drive mechanism (20) is positioned below the turntable (11) whereby the drive mechanism (20) is connected to the turntable (11) via an actuation connection.

2. Magazine unit according to claim 1, characterized by the fact that for all magazine tubes (12 to 16) only one scanning head (27) is provided at a reading station that is located in front of the dispensing station (18) at a path of movement of those sections of the carrier able to move together with the carrier that are transparent in order to read the identifications.

3. Magazine unit according to claim 1, characterized by the fact that adjustment of the carrier or turntable (11) can be controlled via the registration device.
