[0001] DESCRIPTION

[0002] BEVERAGE PREPARATION SYSTEM WITH COMPACT OPERATING DESIGN

[0003] Field of Invention

[0004] The present invention relates to a system comprising a beverage preparation machine operable by means of a cartridge enclosing a portion holder for multiple individual portions of edible substance, for example roasted and ground coffee beans, a precursor to a beverage, for example espresso coffee and similar beverages.

[0005] Background of the Invention

[0006] The state of the art includes solutions relating to a flexible and elongated support comprising a plurality of individual portions, in particular portions of roasted and ground coffee, to be processed successively in the extraction device of a beverage preparation machine, including in a machine for preparing espresso, tea or similar coffee.

[0007] Documents US 598, 639, US 3, 607, 297, US 3, 812, 273, WO 97 / 17006, DE 10248137 A1 disclose supports for individual portions of the type of the present invention.

[0008] Document EP 0653177 BI discloses a method for preparing a coffee beverage with a cartridge comprising a portion holder for individual portions that can be operatively associated with a beverage preparation machine, so that it can supply individual portions of beverage precursor substance carried by the portion holder, successively to a beverage preparation device. The cartridge is in this case arranged so that the tape is only pulled upwards by a traction element that is part of the extraction device, therefore not including a traction device upstream of the extraction device. Furthermore, the cartridge is disposed partially outside the machine casing and has a reduced number of individual portions.

[0009] Furthermore, the state of the art includes document WO 2013 / 169134 A2 registered by the author of the present invention, which discloses an advantageous configuration of a beverage preparation system adapted for use with such a multi-portion holder, and which further discloses some arrangements relating to the cartridge and traction element upstream of an extraction device.

[0010] Beverage preparation systems of this type raise several technical problems due to their simple construction and efficient operation.

[0011] In the case of cartridges with a relatively high number of individual portions, including more than 10 individual portions, questions arise regarding the possibility of a more efficient and reliable displacement of a portion holder that has a greater length and total weight of support to pull, as well as how easy it is to store it inside a collection package for the holder, for example in a zigzag arrangement extending vertically.

[0012] The relative arrangement of the cartridge in its operating position on the beverage preparation machine can determine the outcome of issues related to the possibility of more efficient and reliable displacement of the support by a traction device on the machine, as well as a more ergonomic layout on the machine.

[0013] Document EP 0457708 Al also discloses a beverage preparation system including a collection packaging of a flexible, elongated support for individual portions in a ribbon-type configuration of the type of the present invention. In particular, the document discloses the ribbon arrangement in a zigzag-type arrangement vertically inside the packaging and with the portions in a staggered manner, the ribbon being pulled from a top region of the packaging and in a generally vertical direction for supply to the beverage preparation machine.

[0014] Documents WO 2016 / 048181 Al and WO 2016 / 048182 Al, registered by the author of the present invention, disclose solutions for moving the individual portion holder of the type of the present invention, from the collection packaging thereof to an extraction device located downstream. Document WO 2016 / 048181 Al includes a schematic representation of a machine that has a cartridge compartment inside the machine, but does not detail particular aspects of the relationship of this compartment with other characteristics of the machine.

[0015] Documents WO 2016 / 013034 Al and WO 2016 / 130035 Al, also registered by the author of the present invention, disclose advantageous configurations of packaging for collecting individual portion holders of the type of the present invention.

[0016] Documents WO 2021 / 118376 Al and WO 2021 / 118377 Al, also registered by the author of the present invention, address several of these aspects.

[0017] The expert in the field is thus faced with the problem of how to configure the system in order to improve the efficiency and reliability of traction from the portion holder to the beverage preparation device, thereby also providing more compact and efficient machines. Furthermore, various dimensional and constructive aspects of the cartridge configuration and its collection compartment in the machine are also relevant for greater operational and usability efficiency. This problem can therefore involve a relatively large number of combinations of various aspects, including dimensional relationships. In this sense, the author conducted several tests to determine which combinations of dimensional aspects of the machine and cartridge can provide the best operational results.

[0018] General Description of the Invention

[0019] The present invention relates to a system comprising a cartridge-operable beverage preparation machine having a cartridge housing enclosing a portion holder including a plurality of individual portions of edible substance, and operable by means of traction so that the individual portions can be successively fed to an extraction device.

[0020] The objective of the present invention is to disclose a system of this type that enables more efficient and reliable cartridge actuation by a traction device, as well as a more efficient and compact construction machine.

[0021] The above objective is solved according to the present invention by means of a beverage preparation system according to claim 1.

[0022] In particular, the above objective is achieved through a system in which the cartridge is operable by the machine in an operating position where the cartridge box does not extend more than 20% of its height in at least one of the following: above the top level of the upstream traction device, and below the top level of the waste collection container.

[0023] This arrangement of the cartridge in the operating position advantageously provides reliable and efficient movement of the portion holder via the machine's traction means.

[0024] This relative arrangement of the cartridge's operating position provides a more compact machine configuration and more reliable delivery of individual portions to the extraction device, particularly if the cartridge comprises at least 30 collection compartments.

[0025] An associated objective of the present invention is to disclose a system that provides more efficient cartridge operation, in particular more efficient movement of the portion holder by the traction device.

[0026] This objective is achieved by a system configured in such a way that the cartridge and the traction device are operably linked functionally through the support portions, so that they interact by means of a force transmitted and directed in at least approximately a horizontal direction, or with a greater force component in the horizontal direction.

[0027] The system can be configured so that a cartridge operable by the beverage preparation machine, such that the portion holder can be pulled out of the cartridge box, defining an angle between 0 oand 45° relative to the horizontal direction, along at least most of, preferably the entire length between the cartridge box outlet and the traction device of the beverage preparation machine, i.e., of a first extension of the portion holder outside the cartridge box.

[0028] This advantageously reduces the forces required on the traction and actuation mechanisms.

[0029] Furthermore, according to a second aspect, the cartridge is operationally associable with the machine in such a way that when the cartridge is in the operational position, the second extension of the portion holder comprises an upstream ascending segment oriented in an oblique direction and a downstream descending segment oriented in a vertical direction.

[0030] The combination of these two aspects helps to reduce the need for actuation and increases the reliability of feeding individual portions from the cartridge.

[0031] The cartridge is operable by the machine, and the portion holder is configured so that it can be actuated by the machine's traction and actuation devices, including being pulled by a traction device, and provided step-by-step to an extraction device on the beverage preparation machine.

[0032] Furthermore, according to another aspect, the system is provided so that the cartridge can be positioned in an operating position in such a way that the portion support can be rotated by the traction device in a second extension less than three times the step extension between successive collection confinements, still upstream of the extraction device.

[0033] The system can be configured so that the operating association of the cartridge to the machine requires that the portion support be pulled out of the cartridge box in an upward direction and in a first extension less than three times the pitch (p), preferably less than twice the pitch (p), particularly preferably in a first extension at least approximately corresponding to the portion support pitch (p) or the distance (q) between successive collection confinements, so that a first collection confinement can interact with the traction device and a second collection confinement is located next to the cartridge box outlet opening.

[0034] The system can be configured so that the cartridge is operable in the machine in such a way that a longitudinal central axis of the portion holder is arranged at least approximately aligned in the same vertical plane as a central axis that is common to the traction device and the extraction device of the beverage preparation machine.

[0035] It is further preferred when the cartridge can be operatively associated with the machine in such a way that the outlet opening of the cartridge case is at a level above or below, preferably at least approximately horizontally aligned with, the traction device, and it is preferred when the outlet opening is provided in such a way as to induce a variation in the direction of displacement of the support portions between a prevailing direction of this inside and outside the cartridge, upstream and downstream of the outlet opening, respectively.

[0036] This provides a more efficient arrangement in terms of the displacement requirements of the portion holder between the cartridge box and the traction device, as well as a more compact beverage preparation machine.

[0037] Within the scope of this description, the front of the machine is considered to be the part where the beverage discharge and / or the machine's user interface is provided, and is generally represented on the right side of the drawings.

[0055] Detailed Description of the Invention

[0056] As known in the state of the art and represented in Figures 1 and 2, a cartridge (3) can be part of a system for preparing edible products, for example coffee-based drinks, such as espresso coffee.

[0057] A cartridge (3) of the type of the present invention comprises a cartridge box (31) configured so that it collects a portion holder (1) comprising a plurality of collection confinements (130) that confine an individual portion (2) of edible precursor substance for beverage preparation. The cartridge (3) is associable with the machine (10) in an operating position in which the portion holder (1) is arranged at least approximately aligned in the same vertical plane as an axis of symmetry and / or center of the traction device (101) and extraction device (102), when viewed from the front view of the machine (10).

[0058] If the cartridge (3) is in the operating position, the portion holder (1) is operable so that it can be actuated by the machine's traction and actuation devices (10), including being pulled by a traction device (101) which is actuated by an actuation device, for example an electric motor (not shown) and regulated by control means (not shown) so that it can be supplied step-by-step to an extraction device (102) arranged downstream of the traction device (101) in the machine (10).

[0059] In general, in the case of known systems, the cartridge (3) is operable at a first vertical distance (Xi) and a second horizontal distance (X2) between the outlet opening (32) and an interaction region with the traction device (101) which leads to higher traction requirements and larger machine dimensions.

[0060] According to a state-of-the-art solution, and also schematically represented in Figure 1, the system can be configured so that a further downstream collection portion (13) is separated by means of a cross-section in the region between collection portions (13), from the remaining support (1) of portions is thus moved to the extraction device (102) only by the action of gravity.

[0061] With regard to the distribution inside the cartridge box (31), several possibilities are known for arranging the portion support (1), including such that collection confinements (130) of successive row segments, or their respective central axes (X), are alternately offset from each other relative to a subsequent row and aligned with those of a second row upstream or downstream, as schematically represented in Figure 2. The cartridge (3) includes a parallelepiped-shaped cartridge box (31) that confines a portion support (1) folded in a zigzag pattern in successive rows along the height (H3) of the cartridge box (31) and such that a downstream end of the support (1) is located near an outlet opening (32).

[0062] The most downstream end of the support (1) of portions is disposed in proximity to an outlet opening (32) of the cartridge case (31), and the outlet opening (32) is provided in a corner region of the cartridge case (31), such as a corner region including part of at least one of the top wall and front wall of the cartridge case (31).

[0063] As the reader will readily realize, and considering the dimensions of a collection enclosure ( 130 ), the dimensions and number of individual portions ( 2 ) contained in a given collection volume of the cartridge box ( 31 ) are parameters that determine the overall dimensions of the cartridge ( 3 ) and the frequency of need for replacement of the cartridge in the machine ( 10 ), and the ease of handling of the cartridge by a user of the beverage preparation system, as well as related transport and storage costs.

[0064] Furthermore, the length (L3) and height (H3) of the cartridge box (31) are parameters that can determine the overall dimension of the machine (10).

[0065] The present description then addresses aspects of a cartridge (3) in a system according to the present invention.

[0066] Figures 3 and 4 include views of a support segment (1) of portions, and a portion of the support (1) of portions collected in a cartridge box (31), respectively.

[0067] 0 support ( 1 ) of portions presents a plurality of collection confinements ( 130 ) configured in such a way that they confine a respective individual portion ( 2 ) within the same .

[0068] The individual portion (2) may comprise roasted and ground coffee beans, preferably at least in the greater part of their mass fraction, or other edible substance for preparing beverages by infusion or extraction thereof. The individual portion (2) is advantageously a portion of roasted and ground coffee beans, in particular weighing between 5 and 7 g.

[0069] The individual portion (2) is advantageously provided in the form of a pre-compacted tablet of edible substance, for example roasted and ground coffee beans. The individual portion (2) is advantageously a compacted tablet of roasted and ground coffee beans with a hardness between 10 and 30 N.

[0070] 0 support ( 1 ) of portions has only two support sheets ( 11, 12 ) arranged in juxtaposition along a longitudinal connecting plane, wherein the two support sheets ( 11, 12 ) extend along at least most of, preferably the entire width and the entire length of said support ( 1 ) of portions.

[0071] The distance between corresponding points of successive collection confinements (130) defines a step (p), and successive collection confinements (130) are proportioned apart from each other by a free distance (q).

[0072] 0 support ( 1 ) of portions includes, in a preferred mode, two support sheets ( 11, 12 ) and a plurality of individual portions ( 2 ) collected in successive respective collection portions ( 13 ).

[0073] The collection confinements ( 130) advantageously present a disc-type format, with a height (H 30) of confinement smaller than a characteristic cross-sectional dimension (Q3) of the collection confinement ( 130) .

[0074] It is preferred when the support ( 1 ) of portions is provided in such a way that the collection confinements ( 130 ) have a characteristic collection dimension (Q3o) between 30 and 50 mm, preferably between 35 and 45 mm.

[0075] The height (H 30The size of the collection enclosures (130) may be between 6 and 12 mm, preferably between 7 and 11 mm. The Applicant has experimentally determined that this dimension provides good results in terms of coffee extraction and provides greater stability of the portion holder (1) within the cartridge box (31). Furthermore, the collection portions (13) include annular connection regions (14) that extend radially with a characteristic transverse connection dimension (Q) from the side wall (15) of the collection enclosure (130), and do not extend along the entire free distance (q) between successive collection enclosures (130) nor along a width (r) of free side margins of the portion holder (1).

[0076] It is preferred when the support ( 1 ) of portions is provided so that the ratio between the bonding surface area of ​​the bonding regions ( 14 ) and the area of ​​the collection confinements ( 130 ) in the bonding plane (Y ) is between 1 . 5 : 1 and 5 . 0 : 1 , preferably between 2 . 0 : 1 and 3 . 0 : 1 , so that the bonding region ( 14 ) has a sufficient material bonding surface relative to the characteristic dimension of the collection confinements ( 130 ).

[0077] Figure 4 represents part of a support arrangement ( 1 ) of portions, such as this can be carried out inside a cartridge box ( 31 ).

[0078] According to one aspect, the cartridge (3) comprises a support (1) of portions arranged so that the height occupied by three successive folded rows is less than 2.5 times the height (H 30 ) of the collection confinements ( 130 ) .

[0079] Furthermore, it is preferred when the height occupied by three successive folded rows corresponds at least approximately to twice the height (H). 30 ) of the collection confinements ( 130 ) .

[0080] According to another aspect, the cartridge box (31) can collect a support (1) of portions presenting collection confinements (130) spaced apart by a step (p) equal to or greater than the characteristic dimension (Q3o) of the collection confinements (130).

[0081] This provides a more compact arrangement of the collection portions (13) in the cartridge box (31), with fewer empty spaces between collection confinements (130) of row segments in a zigzag arrangement of the portion holder (1). It is thus advantageously provided that collection confinements (130) of a first row are interleaved between collection confinements (130) of a second row underneath the first row, in particular so that at least most, preferably the whole length of a lower half of the collection confinement (130), i.e., corresponding at least approximately to half the height (H). 30 ) of the collection confinements ( 130 ), remain collected in the projection space between the upper halves of collection confinements ( 130) of a row underneath.

[0082] It has been shown to be advantageous when the cartridge (3) comprises a support (1) of portions arranged so that the side walls (15) of collection confinements (130) of adjacent vertical alignments result in laterally aligned extensions of half the height (H 30 ) of the collection confinements ( 130) and, in addition, result adjacently and in such a way that they do not support each other laterally, or at a distance less than half the height (H 30 ) of the collection confinements ( 130) .

[0083] Furthermore, the cartridge ( 3 ) comprises a support ( 1 ) of portions arranged so that it forms vertical alignments in which the base regions of collection confinements ( 130 ) of a first row rest directly on the top regions of collection confinements ( 130 ) of a second row, preferably along at least the greater part of the characteristic collection dimension (Q3o) thereof.

[0084] As represented in the drawings of Figures 5 to 10, the beverage preparation system according to the invention is configured so that the cartridge (3) can be placed by a user in a previously defined operating position and is located at least partially, preferably completely inside the machine (10), i.e., inside the machine box (100).

[0085] Furthermore, the system is configured so that the cartridge (3) is operable by a user from a front region of the machine (10). Figures 5 to 7 represent a first embodiment of systems in which the means of actuation of the machine (10) for actuation of the portion holder (1) include a traction device (101) disposed in close proximity and directly opposite in front of the cartridge box (31), in particular the region of the outlet opening (32), and disposed also in close proximity and at least approximately above the extraction device (102).

[0086] According to one aspect, the system according to the present invention is provided in such a way that the cartridge (3) can be manually placed into an operating position through a common access space for retention and functional connection of the cartridge (3) in the operating position, i.e., that provides user manipulation of the cartridge (3) and functional association of the portion holder (1) with the traction device (101) inside the machine box (100).

[0087] 0 common access space is advantageously provided so that access is regulated in functional connection with machine control means ( 10 ).

[0088] The common access space is confined by the box (100) inside the machine (10), preferably accessible only through an access portion (110) provided so that its operation can be detected by the machine (10). In particular, the machine (10) may advantageously comprise control means and sensors provided so that they prevent, or if necessary interrupt, the operation of the traction device (101) and fluid circulation means, in the event that an operation of the access portion (110) is detected.

[0089] Furthermore, the system is provided in such a way that the cartridge (3) can be manually placed into an operating position in a common access space from the front region of the machine (10).

[0090] This provides advantageously simpler and more ergonomic handling of the cartridge (3), as well as a more efficient and compact configuration of the machine (10).

[0091] The system can be provided in such a way that the cartridge (3) can be placed in the operating position by means of movements of the cartridge case (31) and the support (1) of portions that extend into the common access space.

[0092] Alternatively or complementarily, the system can be provided in such a way that the cartridge (3) can be placed in the operating position by means of movements of the cartridge box (31) supported laterally towards the interior of the machine (10) and of the portion holder (1) towards the front region of the machine (10) which extend into the common access space to the operating positions of both the cartridge (3) and portion holder (1).

[0093] Figures 5 to 7 represent a first embodiment of systems in which the means of actuation of the machine (10) for actuating the portion support (1) include a traction device (101) which is located in close proximity to and directly opposite in front of the cartridge box (31), in particular the region of the outlet opening (32), and which is also located in close proximity to and at least approximately above the extraction device (102).

[0094] According to one aspect, the system according to the present invention is provided in such a way that the cartridge (3) can be manually placed into an operating position by passing the cartridge (3) through a common access space that is configured so as to provide space for retention and functional connection of the cartridge (3) in the operating position, i.e., that provides user manipulation of the cartridge (3) and functional association of the portion holder (1) with the traction device (101) inside the machine box (100).

[0095] The common access space is advantageously provided in such a way that access to the common access space is regulated in functional connection with means of control of the machine ( 10 ).

[0096] The common access space is confined by the box (100) inside the machine (10), preferably accessible only through an access portion (110) which is provided so that an actuation thereof can be detected by means of control of the machine (10). In particular, the machine (10) may advantageously comprise control means and sensors provided so that they prevent, or if necessary interrupt, the operation of the traction device (101) and fluid circulation means, in the event that an actuation of the access portion (110) is detected.

[0097] Furthermore, the system is provided in such a way that the cartridge (3) can be manually placed into an operating position by manipulating the cartridge (3) in a common access space inside the machine (10) by a user reaching from the front region of the machine (10).

[0098] A simpler and more ergonomic handling of the cartridge (3) is thus advantageously provided, as well as a more efficient and compact configuration of the machine (10).

[0099] The system can be provided in such a way that the cartridge (3) can be placed in the operating position by means of movements of the cartridge box (31) and the portion holder (1), such movements extending into the common access space.

[0100] Alternatively or complementarily, the system can be provided in such a way that the cartridge (3) can be placed in the operating position by means of movements of the cartridge box (31) supported laterally towards the interior of the machine (10) and of the portion holder (1) towards the front region of the machine (10), such movements extending into the common access space to the operating positions of both the cartridge (3) and the portion holder (1).

[0101] According to another aspect, the system according to the present invention is provided in such a way that the cartridge (3) is operable retained in an operating position relative to a cartridge compartment opening (110), and functionally connected through that compartment opening, the compartment opening being preferably provided inside and away from the machine housing (100). Furthermore, the system is also provided in such a way that the machine (10) includes a cartridge compartment (110) with a compartment opening having at least one different shape and dimension of an access portion (111) providing access to the interior of the machine housing (110) and to the cartridge compartment (110).

[0102] It is in this advantageously provided way that the cartridge (3) can be operated more efficiently and the machine (10) has a more efficient and compact construction.

[0103] In the case of the embodiment shown in Figures 8 to 10, the cartridge (3) can be introduced into the cartridge compartment (110) through an access portion (111) that extends at least in a front region and, preferably, also in part of a top region of the machine case (10).

[0104] Indeed, as represented, the access portion (111) is configured as a user-operable door-type form so that it can be rotated upwards around a horizontal axis of rotation, thereby providing access to a front region of the cartridge compartment (110).

[0105] The cartridge (3) can be placed inside the cartridge compartment (110) by means of a first linear movement from top to bottom, a rotational movement, and a second linear movement towards the front of the machine (10).

[0106] The cartridge compartment (110) is advantageously configured so that it includes a compartment opening that has a shape approximately equal to the shape of the cartridge case (31) when tilted in a previously defined spatial position corresponding to the position in which the cartridge (3) can be inserted into the cartridge compartment (110).

[0107] Furthermore, the cartridge compartment (110) may have retention means (112) configured so that they project into the interior of the cartridge compartment (110) and thus provide guidance and / or retention of the cartridge case (31) in the operating position.

[0108] As represented, it is advantageous in this case when the traction device (101) can also be moved manually or mechanically, between an operating position and an access position where it provides space for the insertion of the cartridge (3), and vice versa, to the operating position where it is operable by an actuating device, such as an electric motor.

[0109] In particular, it is preferred when the traction device (101) can be rotated up and down around a horizontal pivot axis.

[0110] The machine (10) may have a cartridge compartment (110) and a waste collection container (103) provided inside the housing (100) and preferably configured so that the cartridge compartment (110) and the waste collection container (103) are operable by a user from the front side of the machine (10).

[0111] The machine (10) may have a cartridge compartment (110) and a waste collection container (103) provided inside the machine housing (100) and configured so that the cartridge (3) may be inserted into the cartridge compartment (110) in a direction of insertion, including vertical downward or oblique downward, different from the direction of insertion of the waste collection container (103) which is at least approximately horizontal.

[0112] The machine (10) may have a waste collection container (103) configured so that it can collect collection portions (13) downstream of the extraction device, wherein the waste collection container (103) is configured with a width that is at least 1.5 times, preferably at least 2 times the width of the waste collection container (110) so that it can collect a number of collection portions (13) corresponding to at least 70%, preferably equal to or greater than the number of collection portions (13) contained in the cartridge (3).

It is particularly preferred when the machine (10) is configured so that the total volume occupied by the cartridge compartment (110) and waste collection container (103) is between 40 and 70%, preferably between 50 and 70% of the volume confined by the machine box (10).

[0114] As shown, the waste collection compartment (103) is configured so that it can collect a respective container in a direction that is at least approximately equal to the cartridge insertion direction (3) and also from a front side of the machine (10).

[0115] According to another aspect, the system according to the present invention is adapted so that the cartridge (3) is operable by the machine (10) in such a way that the portion holder (1) defines an angle greater than 0 o and less than 45° relative to the horizontal direction, at least in the region of the first extension in close proximity to the outlet opening (32). It is thus advantageously provided that the traction force requirements of the traction device (101) can be reduced and the machine (10) can have a more compact shape.

[0116] It is preferred when the support (1) of portions defines an angle between 0 o and 40°, preferably an angle between 4 o and 35°, in a particularly preferred manner an angle of up to 15°, relative to the horizontal direction at least in the region of the first extension of the support (1) of portions next to the outlet opening (32).

[0117] It is preferred when the portion support (1) is operated in a second direction at least approximately horizontal, upward or downward from the outlet opening (32) and along at least most of the first extension between the cartridge outlet (3) and the traction device (101), so as to reduce the actuation effort required by the cartridge (3).

[0118] According to another aspect, the system according to the present invention is configured so that the cartridge (3) is operable by the machine (10) in an operating position such that the portion support (1) is pulled by a traction device (101) in a first extension, between the outlet opening (32) of the cartridge (3) and the traction device (101) of the machine (10), less than five times, preferably less than four times, particularly preferably less than three or two times the pitch extension (p) of the collection portions (13).

[0119] Alternatively or supplementarily, the system is configured so that the cartridge (3) can be operated in such a way that the actuation requirement, or required traction force generated by the first support extension (1) of portions to the traction device (101), is less than that corresponding to a weight of 35 g, preferably less than a weight of 28 g, particularly preferably less than 21 g, and greater than a weight of 7 g, preferably greater than a weight of 14 g.

[0120] Figures 11 to 14 represent embodiments of the system according to the invention which provide a simple and compact construction of the machine (10) and efficient means of operating a cartridge (3).

[0121] According to one aspect of the present invention, the system is configured in such a way that the cartridge (3) and the traction device (101) are operably connected functionally through the support (1) portions so that they interact by means of a force transmitted and directed in a direction at least approximately horizontal or with a greater force component in the horizontal direction.

[0122] This provides a more advantageous cartridge position (3), particularly in relation to the traction device (101), resulting in a more compact machine, with more reliable operation and lower actuation requirements.

[0123] In the case of the embodiment shown in Figures 11 and 12, the functional connection of the cartridge (3) is provided by means of arrangement and / or retention of a more downstream end of the portion support (1) in the traction device (101) so that it can pull the portion support (1) from and out of the cartridge case (31) and to a region at least approximately above the extraction device (102). In this case, it is preferred when the more downstream confinement portion (13) is separated from the rest of the portion support (1) in a region associated with the extraction device (102), for example by means of a cutting element associated with a top region of cooperating parts of the extraction device (102) that cut when the latter is closed so that the confinement portion (13) can be separated when inside the latter.

[0124] According to another aspect, represented in Figure 12, the system according to the present invention is provided in such a way that when the cartridge (3) is in the operating position, the second extension of the portion holder (1) comprises a region for separating the individual portion (2) relative to the support sheets (11, 12) so that only the individual portion (2) is provided to the extraction device (102). In this embodiment, the support sheets (11, 12) are retained in the traction device (101).

[0125] In the case of the embodiment shown in Figures 13 and 14, the two most adjacent ends of the support sheets (11, 12) are retained in respective elements of the traction device (101), so that the movement of the same generates a removal of the connecting link between the support sheets (11, 12), thus releasing the edible portion (2) which is supplied to the extraction device (102) devoid of support sheets (11, 12).

[0126] According to one aspect, the system can be configured in such a way that it provides separation of materials, i.e., of the support sheets (11, 12) from the individual portions (2), using only the energy required by the movement of the support (1) of portions up to the traction device (101), and without requiring energy solely for this purpose.

[0127] The system can be configured so that the cartridge (3) is operable in such a way that the individual portions (2) are moved between the outlet opening (32) and the extraction device (102) in at least the greater part of the extension, preferably in the entirety of the extension in a direction not contrary to the force of gravity. Furthermore, the system can be configured so that the cartridge (3) is operable in such a way that the individual portions (2) are moved between the traction device (101) and the extraction device (102) according to at least one of: moved, preferably only, by the force of gravity; and in an extension that corresponds to at most seven times, preferably at most five or four times, particularly preferably at most three times the pitch (p).

[0128] According to another aspect, the system according to the present invention is configured so that the portion support (1) is pulled by the traction device (101) in each actuation step to a maximum extension corresponding to at least one of: an extension of up to eleven times the step (p), preferably between five times and eleven times the step (p), and a weight of up to 77 g, preferably between 20 g and 77 g.

[0129] This advantageously provides a reduction in the traction force requirements of the traction device ( 101 ) so that the machine is operable more efficiently and can have a more compact shape.

[0130] Furthermore, the system can be configured so that the support (1) of portions is pulled by the traction device (101) according to at least one of:

[0131] - in a maximum support extension ( 1 ) of portions that in each actuation step corresponds to at least one of: an extension between six and ten times the step (p) , preferably up to nine times, particularly preferably up to eight times the step (p) , and a weight between 30 g and 70 g, preferably up to 60 g, particularly preferably up to 50 g;

[0132] - in a first support extension ( 1 ) of portions that in each actuation step corresponds to at least one of : an extension between one time and five times the step (p) , preferably up to three times the step (p) , and a weight that does not exceed 63 g , preferably does not exceed 56 g , particularly preferably does not exceed 49 g ; - in a second support extension ( 1 ) of portions that corresponds to at least one of : an extension that does not exceed four times , preferably does not exceed three times , particularly preferably does not exceed two times or one time the step (p) , and a total weight that does not exceed 35 g , preferably does not exceed 28 g , particularly preferably does not exceed 21 g .

[0135] - at least four times and at most twelve times the portion support pitch (p), preferably at least five times and at most ten times the portion support pitch (p), particularly preferably at most eight times the portion support pitch (p). Furthermore, the system can be configured so that the cartridge (3) is operable in an operating position according to at least one of:

[0136] - such that a smaller vertical distance of displacement path (Zi) between the exit opening (32) and the traction device (101) does not exceed three times the pitch (p), preferably does not exceed twice the pitch (p), in a particularly preferred way does not exceed or is less than one time the pitch (p);

[0138] It is further preferred when the cartridge (3) is operatively associable with the machine (10) so that the path distance between the outlet opening (32) and the extraction device (102) does not exceed six times the pitch (p), preferably does not exceed five times the pitch (p), in a particularly preferred way does not exceed four or three times the pitch (p).

[0139] It is preferred when the system is configured so that the cartridge (3) includes a cartridge box (31) that can hold a portion holder (1) that holds at least 50, particularly preferably at least 60 individual portions (2), and that preferably has a length (L3) greater than the height (H3), preferably at least twice the height (H3).

[0140] It is further preferred when the system is configured in such a way that the traction device (101) can be actuated in step-by-step mode by an actuating device which has at least one of: a rated power of up to 70 W, preferably between 10 and 50 W, particularly preferably between 15 and 40 W, and it is preferred when the actuating device has a maximum torque of up to 1 Nm, preferably between 0.01 and 0.5 Nm, preferably between 0.1 and 0.4 Nm.

[0141] The system can be advantageously configured so that the portion support (1) is pulled by the traction device (101) over a total extension between the outlet opening (32) and the extraction device (102) corresponding to at least four times and up to ten times the portion support pitch (p), preferably up to seven or six times the portion support pitch (p).

[0142] It is further preferred when the cartridge (3) is operatively associable with the machine (10) so that the path distance between the outlet opening (32) and the extraction device (102) does not exceed six times the pitch (p), preferably does not exceed five times the pitch (p), in a particularly preferred way does not exceed four or three times the pitch (p).

[0143] According to one aspect, the system can be configured so that the cartridge (3) is operable in such a way that the individual portions (2) are moved between the outlet opening (32) and the extraction device (102) in at least most of the path length, preferably in the entire path length, in a direction not contrary to the force of gravity.

[0144] As represented in all embodiments of Figures 11 to 14, it is advantageous when the cartridge (3) is operable in a position where the top wall is at a level that is no higher than the level of the top region of the traction device (101) inside the machine (10).

[0145] Furthermore, in the case of the embodiment of Figures 12 and 14, the cartridge (3) is operable in a position where it is arranged at a level above the top level of the extraction device (102).

[0146] It is further advantageous when the cartridge (3) can be operatively associated with the machine (10) in such a way that a central axis of the outlet opening (32) of the cartridge (3) is disposed at a level above or below in an extension of up to twice the pitch (p), preferably up to one time the pitch (p), relative to at least one axis of rotation of the traction device (101), preferably at least approximately horizontally aligned with at least one axis of rotation of the traction device (101).

[0147] It is further preferred when the system is configured so that the outlet opening (32) induces a variation in the direction of movement of the portion holder (1) between a prevailing direction of movement inside the cartridge case (31), preferably at least along part of the operating range of the portion holder (1), which is the range that is moved outward from an initial storage arrangement of the portion holder (1) inside the cartridge case (31), and a prevailing direction of movement of the portion holder (1) outside the cartridge case (31), it being further preferred when said variation in direction configures an angle of up to 120° along part of the operating range, or up to 90° along another part of the operating range. Furthermore, according to another aspect, the system is configured so that the cartridge (3) is operable by the machine (10) according to at least one of:

[0148] - so that all the collection portions (13) in a first extension of the support (1) for portions outside the cartridge box (31) are pulled in an upward direction to a height extension less than the height (H3) of the cartridge; - so that all the collection portions (13) in a first extension of the support (1) for portions outside the cartridge box (31) are pulled in an upward direction to a height extension that is less than four times, preferably less than three times the height (H 30 ) of the collection confinements ( 130 ) of the portion holder ( 1 ); - so that the totality of the collection portions ( 13 ) in a first extension of the portion holder ( 1 ) outside the cartridge box ( 31 ) are pulled in a direction that is at least approximately horizontal and / or downward.

[0149] Any of the aspects mentioned above contributes individually and jointly to a lower actuation force requirement by the traction device (101), and lower risks of alteration of the trajectory of the support (1) of portions between the cartridge box (31) and the traction device (101), as well as to a machine (10) having a more compact format.

[0150] It is preferred when the cartridge ( 3 ) is operable in the operating position such that the outlet opening ( 32 ) is at a vertical distance and a horizontal distance from the traction device ( 101 ), wherein either of the said vertical and horizontal distances does not exceed three times, preferably does not exceed twice, preferably does not exceed twice the pitch (p ) of the portion support ( 1 ).

[0151] Furthermore, it is preferred when the cartridge (3) can be operatively associated with the machine (10) so that the outlet opening (32) is at a level above or below less than twice the pitch (p), preferably less than once the pitch (P). It is particularly advantageous when the cartridge (3) is operable so that the outlet opening (32) is at a level at least approximately horizontally aligned with at least one of: the traction device (101) and at least one axis of rotation thereof.

[0152] It is preferred when the cartridge (3) is operable in such a way that the outlet opening (32) induces a variation of direction in the support (1) of portions between a prevailing direction inside and outside the cartridge (3).

[0153] In this embodiment, the system is provided so that the cartridge (3) has a height (H3) that does not exceed the total height occupied by the traction device and extraction device (102) inside the machine (10). In other words, the cartridge (3) occupies a height confined by the horizontal projection delimited by the top level of the traction device (101) and the base level of the extraction device (102).

[0154] 0 extraction device ( 102 ) can be arranged at a level inside the machine (10) so that it extends at least partially into the horizontal projection of the cartridge (3) in the operating position.

[0155] It is preferred when the extraction device (102) is arranged at a level below the level of the cartridge (3) when in the operating position inside the machine (10), in a preferred manner so that it does not extend into the horizontal projection of the cartridge (3) in the operating position.

[0156] According to a preferred embodiment, the cartridge (3) is operable in the operating position such that the top level of the cartridge box (31) does not differ by more than 20%, preferably by more than 10% from the top level of the traction device (101), preferably at least above the base level or at least above the top level of a waste collection container (103) disposed under the traction device (101).

[0157] Furthermore, the cartridge (3) is operable in an operating position such that the cartridge box (31) extends from a top level below a top level of the box (100) to a base level that is above the base level of the machine box (100), preferably at least above at least one of: the base level and the top level of a waste collection container (103) disposed under the traction device (101) and the extraction device (102).

[0158] Although represented here only schematically, the waste collection container (103) may have a volume with a collection capacity of at least 70%, preferably more than 1.5 times the number of individual portions (2) contained in a cartridge (3). The cartridge (3) contains at least 50, preferably at least 60 individual portions (2).

[0159] Furthermore, it is preferred when the cartridge (3) is operable in an operating position where the respective base wall of the cartridge box (31) is at a level above the level of the top region of a waste collection container (103) located below the traction device (101) and the extraction device (102).

[0160] Figures 15 and 16 represent two embodiments in which the cartridge (3) is operable such that the portion holder (1) is pulled by the traction device (101) and the cartridge (3) has an outlet opening (32) that extends only on the top wall of the cartridge box (31), preferably at least in the vicinity of a corner region thereof.

[0161] According to an advantageous aspect, the cartridge (3) in this case has an outlet opening (32) that extends only on the top wall of the cartridge case (31).

[0162] It has also been shown to be advantageous when the outlet opening (32) extends in this case along only part, preferably along a smaller part of the length (L3) of the cartridge case (31).

[0163] It is preferred when the outlet opening (32) extends from a region at least in the vicinity, preferably at least in the vicinity of the corner between the top wall and the front wall of the cartridge case (31). Furthermore, according to another aspect, the system is advantageously configured so that the cartridge (3) is operable in a position where the height (H3) of the cartridge (3) is contained within the horizontal projection defined jointly by the traction and extraction devices (102), i.e., it does not extend above or below the space jointly occupied by these.

[0164] In the case of the embodiment shown in Figures 15 and 16, the cartridge (3) is operable in a position where the top wall of the cartridge case (31) is positioned below the level of the top surface of the extraction device (102), but above the level of the base surface of the traction device (101).

[0165] It is preferred when the top level and / or the base level of the cartridge case (31), preferably both, is above the level of the top surface of the extraction device (102), and it is preferred when the extraction device (102) is located below the traction device (101).

[0166] It is preferred when the base level of the cartridge box (31) is at least above the base level of a waste collection container (103), preferably above the top level of a waste collection container (103), and it is preferred when the waste collection container (103) is located below the extraction device (102).

[0167] In particular, in the case of Figure 15, the cartridge (3) is operable in an operating position where the top wall of the cartridge case (31) is at a level below the top level of the traction device (101) and the base wall of the cartridge case (31) is at a level at least approximately equal to or above the extraction device (102).

[0168] According to an advantageous aspect, the cartridge (3) is operable in an operating position where the top wall is at least approximately at the level of at least one of: the traction device (101), axes of rotation thereof.

[0169] In the case of Figure 16, the rotation axes of the traction device (101) are arranged at a level below the top wall of the cartridge box (31), preferably at a distance corresponding to at least one pitch (p). This provides more space inside the box (100) for introducing the cartridge (3) into the cartridge compartment (110) from a front region of the machine (1).

[0170] Furthermore, the extraction device (102) is disposed entirely below the cartridge (3) so that the distance to the traction device (101) is reduced.
