DEVICE FOR DELIVERING AND EXPELLING CAPSULES FOR DELIVERING MACHINES FOR INFUSION BEVERAGES

The present invention refers to a device for delivering and expelling capsules for delivering machines for infusion beverages; the present invention further refers to a delivering machine for infusion beverages equipped with such device.

Delivering machines for infusion beverages are already known in the art, such as for example for delivering tea or coffee contained in capsules, equipped with several types of devices for removing used capsules once the beverage has been prepared and delivered.

For the correct operation of such machines, it is fundamental that the positioning of the capsule inside the device always happens correctly in such a way as to allow the necessary device seal: in fact, a bad positioning could damage the capsule and impair the infusion of the substance contained therein.

Also loading the capsule inside the device must be as practical, easy and quick as possible, in order not to impair the real easiness of use of these delivering machines .

Known devices therefore have different configurations of mechanisms and kinematisms whose tasks are substantially to try and make it easier to insert and position the capsule inside the machine and to perform a sufficiently high seal around the capsule itself in order to be able to perform its extraction at relatively high, typical operating pressures. In known devices, therefore, the capsule must be placed by the user on a suitable capsule support or in an housing in order to then manually or automatically proceed to close the device to take the capsule in an infusion and delivering position.

The art proposes devices that provide for introducing the capsule along a vertical plane and for moving the extraction or infusion parts along a horizontal plane around the capsule: in particular, positioning of the capsule for its extraction occurs due to the movement of at least one moving part that pushes the capsule against another part that takes care of delivering hot water and of performing the capsule infusion. Such devices, though they allow a quick and practical capsule loading, are however extremely complex to make and are not suitable for inexpensive coffee machines: in fact, due to their excessive complexity, they are generally aimed for costly delivering machines for restoration, bars or communities.

For example, patent WO 98/47418 discloses a device for extracting pre-dosed capsules in which the capsule has been inserted vertically and extracted horizontally. The inconvenience of this device is that it comprises, to perform the capsule extraction, two mutually moving parts, this making the mechanism relatively complex.

Patent EP 0 717 603 discloses a device for infusing wafers comprising means for guiding and holding the wafer made as moving abutments that are horizontally pushed by a moving piston towards the device for delivering hot water. In particular, this device provides that the abutments return to their initial position due to a spring in order to remove the wafer, that afterwards falls due to gravity effect when abutments are actuated in rotation to be opened downwards. Such device however requires, obviously, the realisation of multiple combined movements of the means for driving and holding the water, making the device itself extremely complex and costly to make .

Patent EP 1 219 217 discloses a device comprising a moving housing for the capsule oscillating between a capsule-receiving position and a capsule-extracting position. The moving housing is then pushed against the device for delivering hot water by a piston that moves horizontally when the housing itself is in a vertical position. The expulsion of the capsule after infusion occurs through a further downward housing oscillation. Also in this case, the number of moving parts necessary for operating the device is such as to make this latter one extremely complex, costly and scarcely reliable.

Patent WO 2005/004683 discloses a device for extracting a capsule comprising a first part, a second moving part with respect to the first part, a housing for the capsule defining, in a closing position of the second moving part against the first part, an extraction position of the capsule along an axis in such housing, a part for introducing and positioning the capsule arranged in order to allow inserting the capsule by gravity and positioning such capsule in an intermediate position, the second moving part being adapted to move the capsule from the intermediate position to the extraction position upon closing the device. In particular, this device requires, for extracting the capsule, the use of several moving parts such as, among the others, an extraction plaque comprising, as means for guiding the capsule, two members rotating around an axis and a movement finger of an actuating lever. Also in this case, therefore, the described device is relatively complex and costly.

The art further proposes other devices in which the capsule is kept for delivery and afterward expelled by means of one or more linkages elastically cooperating with the device structure.

Object of the present invention is solving the above prior art problems by providing a device for delivering and expelling capsules for delivering machines for infusion beverages that is simpler, less costly and mechanically more reliable with respect to what is proposed by the prior art.

Moreover, an object of the present invention is providing a delivering machine equipped with a device for delivering and expelling capsules that can be practically used and relatively inexpensive.

The above and other objects and advantages of the invention, as will appear from the following description, are obtained with a device for delivering and expelling capsules for delivering machines for infusion beverages as claimed in claim 1.

Moreover, the above and other objects and advantages of the invention are obtained with a delivering machine equipped with a device for delivering and expelling capsules as claimed in claim 11.

For briefness, herein below descriptions will obviously not be made about parts and components common with other devices for delivering infusion beverages and necessary for the basic operation of the device, that are anyway deemed widely known in the art or within reach of any technician in the field, in order to more deeply deal with aspects and components characterising the device for delivering and expelling and the delivering machine equipped with such device according to the present invention.

Therefore, with reference to Figures 1 to 10, it is possible to note that, in a first preferred embodiment thereof, the device for delivering and expelling 1 according to the present invention comprises: at least one first fixed part 3, preferably comprising at least one filter-holder chamber 5; at least one second part 1 , moving with respect to the first fixed part 3, such second part 7 comprising supporting means 9 of at least one capsule 11 cooperating with expelling means 13 for such capsule 11 and at least one water-delivering assembly 15, usually heated water, such second part 7 being moving with respect to the first fixed part 3 through actuating means 17 between a first loading position (FIG. 1, 2 and 3) of the capsule 11 on the supporting means 9, a second position for extracting and delivering the beverage (FIG. 6 and 7) in which the capsule 11 is taken by the second moving part 7 inside the filter-holder chamber 5 and a third position for expelling the capsule 11 (FIG. 8, 9 and 10) from the device 1, and in particular from the supporting means 9, through the expelling means 13.

In particular, the second moving part 7 is equipped with a horizontal sliding movement with respect to the fixed part 3. In order to perform such movement, the actuating means 17 are preferably made as at least one toggle mechanism comprising at least one actuating lever 19 rotating around at least one first rotation shaft 20 which is substantially horizontal and cooperating by interposing at least one toothed coupling 21 with the system composed of a crank 23, rotating around at least one second, substantially horizontal rotation shaft 24, and a connecting rod 25, the connecting rod being connected by interposing at least one hinge 27 to the second moving part 7. Under the action of the actuating means 17, the second part 7 therefore slides with respect to the first fixed part 3 along guiding rails 29 in order to cyclically pass from the first loading position of the 009/005187

capsule 11 on the supporting means 9 to the third position for expelling the capsule 11 through the second position for extracting and delivering the beverage in which the capsule 11 is taken inside the filter-holder chamber 5. Obviously, the actuating means 17 can be made through any other manual or automatic kinematism or mechanism, for example through hydraulic, electric or mechanical systems, that allows conferring the necessary movement to the second moving part 7, without therefore departing from the scope of the present invention.

The above solution is rendered still more innovative by the provision of the toothed coupling 21 in which at least one, but preferably, both gears 21a, 21b are ellyptical gears: with such arrangement, two advantages are obtained:

1 - the opening angle of the actuating lever 19 is less than 90° (viewed from one side) differently from all prior art mechanisms of this type: this allows reducing the movement space of the lever 19 obtaining the same opening position of the prior art devices with a lower stroke;

2 - upon closing the lever 19, the two ellyptical gears 21a, 21b reach a position as shown in Figures 6 to 8 and from Fig. 16 to Fig. 17, in which the lever 19 has its closing movement facilitated by the ellyptical coupling, where the two gears 21a, 21b operate as "reducer" when the maximum force is required to a user in order to complete the lever 19 stroke by pushing it down onto the device 1. The mutual relationship between the two gears 21a, 21b can be well seen in Figures 11, 12 and from 15 to 17 in their main operating positions.

The supporting means 9 of the second moving part 7 preferably comprise at least two branches 9a, suitably shaped in order to house and keep the side profile of the capsule 11 against the water-delivering assembly 15: the insertion of the capsule 11 inside the device 1 preferably occurs in a substantially vertical way, for example through at least one insertion slit 31 adapted to guide the correct positioning of the capsule 11 on the supporting means 9. Moreover, the two branches 9a mutually define at least one space through which the expelling means 13 for the capsule 11 operate. In particular, the expelling means 13, that move integrally with the second moving part 7 under the action of the actuating means 17, preferably comprise at least one rotating shaft 13a having its rotation axis substantially orthogonal to the sliding direction of the second moving part 7 with respect to the first moving part 3, such rotating shaft 13a being equipped, in at least one of its two opposite ends, with at least one actuating connecting rod 13b and, in an intermediate position, with at least one expelling tooth 13c, such tooth 13c being adapted to be inserted, under the rotation action of the rotating shaft 13a, in the space existing between the supporting branches 9a of the capsule 11. The rotating shaft 13a is kept in a rest position by elastic means, preferably made as at least one torsion spring 13d arranged coaxially to the rotating shaft 13a itself.

The rotation of the rotating shaft 13a is determined by the cooperation between the actuating connecting rod 13b and at least one abutment 33, fixed with respect to the second moving part 7 and arranged in such a way as to bump into the actuating connecting rod 13b during the movement of the second moving part 7 to rotate the rotating shaft 13a along a direction coherent with the sliding direction of the second moving part 1, at the same time charging the elastic means 13d that, once having ended the interaction between actuating connecting rod 13b and abutment 33, take back the rotating shaft 13a to its rest position.

Depending on all that has been stated above, an operating cycle of the device for delivering and expelling 1 according to the present invention is as follows : the device 1 is in the first loading position of the capsule 11 on the supporting means 9: a user then loads the device by vertically inserting (along the direction shown by arrow I in FIG. 1) a capsule 11 through the insertion slit 31; the capsule 11 is then arranged on the supporting means 9, and in particular on the two branches 9a (FIG. 2) , that take care of keeping it against the delivering assembly 15; the user operates on the actuating means 17 to take the second moving part 7 towards the second position for extracting and delivering the beverage from the capsule 11: in particular, with reference to FIG. 3, the user operates on the actuating lever 19 by pressing it along the direction shown by arrow V_A; at the same time, due to the toggle mechanism, the second moving part 7 is taken to horizontally slide along the guiding rails 29, along the direction shown by arrow V_c, towards the filter- holder chamber 5; by going on operating on the actuating lever 19 along the direction of arrow V_A, the second moving part 7, in its horizontal movement along arrow V_c, passes through an intermediate position (like the one shown, for example, in FIG. 4) in which the actuating connecting rod 13b of the rotating shaft 13a meets the fixed abutment 33: going on moving horizontally with the second moving 005187

part 7 then generates the sliding of the actuating connecting rod 13b on the abutment 33, generating the simultaneous clockwise rotation of the rotating shaft 13a (along the direction shown by arrow R₀ in FIG. 4) , and therefore the expelling tooth 13c downwards (without any interaction with the capsule 11 that instead is arranged upwards, resting on the two branches 9a), and the charging of the elastic means 13d; always going on operating on the actuating lever 19 along the direction of arrow V_A, the second moving part 7 continues its horizontal movement along arrow V_c to go to another intermediate position (like the one shown, for example, in FIG. 5) in which the actuating connecting rod 13b has passed the fixed abutment 33 and the elastic means 13d, by being discharged, have taken the rotating shaft 13a to its original rest position; always going on operating on the actuating lever 19 along the direction of arrow V_A, the second part 7 is taken to its second position (FIG. 6 and 7), that substantially determines one of the ends-of-stroke of the actuating means 17, in which the capsule 11 is inserted in the filter-holder chamber 5: now the delivering assembly 15 can intervene by delivering water at the most suitable temperature through the capsule 11: such operation can occur according to any one of the modes 5187

known in the art, for example following a manual command performed by the user or an automatic command set by a micro-switch that detects that the second position has been reached by the second moving part 7. Obviously, the filter-holder chamber 5 can be equipped with at least one pouring spout 10 for the beverage infused in the capsule 11 into a glass (not shown) . It must be noted that, preferably, each branch 9a of the supporting means 9 is equipped with an end 9b particularly shaped in order to be adapted to be inserted inside corresponding slits 9b' of the filter-holder chamber 5 to complete their shape and to guarantee their adequate seal against the pressure exerted by the water delivered by the delivering assembly 15; after having ended the infusion and delivering cycle of the beverage, the user operates on the actuating means 17 to take the second moving part 7 towards its third position for expelling the capsule 11: in particular, with reference to FIG. 8 and 9, the user operates on the actuating lever 19 by pulling it along an opposite direction to the one shown by previous arrow V_A, and namely along a direction shown by arrow V_A' : at the same time, due to the toggle mechanism, the second moving part 7 is taken to horizontally slide along the guiding rails 29 along an opposite direction to the one shown by previous arrow V_c, and namely along the direction shown by arrow V_c' ; going on operating on the actuating lever 19 along the direction of arrow V_A' , the second moving part 7, in its horizontal movement along arrow V_c' , reaches the third position for expelling the capsule 11 in which the actuating connecting rod 13b of the rotating shaft 13a again meets the fixed abutment 33, in this case along an opposite direction with respect to what happened previously: then, by going on moving horizontally with the second moving part 7, a sliding is again caused for the actuating connecting rod 13b on the abutment 33, however generating the simultaneous counter-clockwise rotation of the rotating shaft 13a (along the direction shown by arrow R_A in FIG. 8 and 10) and the charging of the elastic means 13d: in this case, however, the expelling tooth 13c is taken to rotate upwards by passing through the space existing between the branches 9a to bump into the capsule 11 and displace it from the branches 9a themselves; the capsule 11 then, lacking the support guaranteed by the supporting means 9, falls by gravity outside the device 1, for example through a suitable lower opening (not shown) to be preferably collected in a tray or in any other recovering container; always going on operating on the actuating lever 19 along the direction of arrow V_A' , the second moving part 7 continues in its horizontal movement along arrow V_C ^Λ in order to go to another intermediate position (not shown) in which the actuating connecting rod 13b has again passed the fixed abutment 33 and the elastic means 13d, being discharged, have taken back the rotating shaft 13a to its original rest position; always going on operating on the actuating lever 19 along the direction of arrow V_A' , the second part 7 is then taken back to its first loading position (FIG. 1) of the capsule 11, that substantially determines the second end-of-stroke of the actuating means 17, making the device 1 according to the present invention ready for a new operating cycle.

FIG. 11 to 14 show a second preferred embodiment of the device for delivering and expelling 1 according to the present invention: the same reference numbers used in FIG. 1 to 10 are also used in FIG. 11 to 14 for the same components having the same functionality, whose description will therefore not be repeated.

With reference to FIG. 11 to 14, the second preferred embodiment of the device 1 is different from the first preferred embodiment of the device 1 in that the second embodiment further comprise at least one abutment tooth 50 whose function is preventing the capsule 11 from falling down by overturning, being misaligned or being offset with respect to the delivering direction, when the capsule 11 is inserted in the device 1, as can be well seen in Fig. 11.

The abutment tooth 50 assumes an opening position (shown in Fig. 12) when the lever 19 is pressed down, the device 1 is closed and the capsule 11 is in its beverage- delivering position; when instead, the lever 19 is lifted and the capsule 11 is taken back to its discharging position (Fig. 11) , the abutment tooth 50 goes back in its closing position (by rotating around its fulcrum-axis 52), waiting for the insertion of a following capsule 11.

The abutment tooth 50 assumes its closing position due to the presence of holding means, preferably made as at least one small magnet 54 (in Fig. 13 and 14, three small magnets 54 are shown) that is inserted in a suitable recess obtained in the abutment tooth 50: since the device 1 is equipped with an abutment wall 56 that is made of metal, the small magnets 54 are attracted towards such abutment wall 56 and keep the abutment tooth 50 in abutment therewith. The force of the small magnets 54 is enough to keep the abutment tooth 50 in its closed position in order to provide an abutment for the inserted capsule 11, preventing it from falling down on the side where the abutment tooth 50 is located; on the other hand, the force of the small magnets 54 can be easily won by the capsule 11 when it is pushed onwards towards its beverage-delivering position (Fig. 12) due to the force applied by the user onto the lever 19.

Another additional feature of the second embodiment of the device 1 shown in Figures 11 and 12, with respect to the first embodiment shown in Figures 1 to 10 is the presence of at least one return spring 60, which helps taking back the small capsule-expelling tooth 13c to its closing position when it is not actuated during the capsule 11 expulsion step.

FIG. 15 to 17 show a third preferred embodiment of the device for delivering and expelling 1 according to the present invention: the same reference numbers used in FIG. 1 to 14 are also used in FIG. 15 to 17 for the same components having the same functionality, whose description will therefore not be repeated.

The difference between the second embodiment and the third embodiment of the device 1 is that, in the third embodiment, parts 13c and 60 are missing, obtaining thereby a cheaper configuration with the same functionality of the second embodiment of the invention.

In fact, the operation of parts 13c and 60 is done by a spring 51 (or equivalent elastic means) that is adapted to engage the abutment tooth 50 when it is in its opening position (Fig. 16) in order to push it downwards as soon as the capsule 11 passes below it, to make the tooth 50 also perform the action of expelling the capsule 11.

Finally, FIG. 18 to 21 show a fourth preferred embodiment of the device for delivering and expelling 1 according to the present invention: the same reference numbers used in FIG. 1 to 17 are also used in FIG. 18 to 21 for the same components having the same functionality, whose description will therefore not be repeated.

The fourth embodiment of the device 1 of the invention has a different arrangement in the part for supporting the capsule 11. Such arrangement substantially comprises :

- at least one first, short spring 70 or other equivalent elastic means;

- at least one second, long spring 72 or other equivalent elastic means;

- at least one first holding member 74 adapted to assume, by rotation around axis 76, a first position

(shown in Fig. 18) in which the capsule 11 is blocked and a second position (shown in Fig. 19, 20, 21) in which the capsule 11 is free of being moved and expelled, said first holding member 74 cooperating with said first, short spring 70 in order to be brought back to its first, blocking position;

- at least one second holding member 82, connected to the first holding member 74 and adapted to assume a first position (shown in Fig. 18) in which the capsule 11 is blocked and a second position (shown in Fig. 19, 20, 21) in which the capsule 11 is free of being moved and expelled, said second holding member 82 cooperating with said second, short spring 72 in order to be brought back to its first, blocking position;

- actuating means 78, 80 (preferably composed of an element 78 connected to a pin 80 which cooperates with a corresponding projection with which the second holding member 82 is equipped, as better shown in Fig. 19) operatively cooperating with said second holding member 82 (and consequently with said first holding member 74 connected thereto) in order to actuate it from its first, blocking position to its second, freeing position.

As it is clear from FIG. 18 to 21, the movement of the first and the second holding members 74 and 82 is controlled by the crank 23 cooperating with the lever 25 on axis 27, as happens in all other previous embodiments of the devide 1 of the invention.

Obviously, the device for delivering and expelling 1 according to the present invention can be integrated in a coffee machine or in any other system for delivering infusion beverages, such as, for example, systems for delivering multiple-beverages, soluble food products, such as cocoa, milk, tea, dehydrated substances for soups or combinations of such products.

Consequently, the present invention further refers to a delivering machine for infusion beverages (not shown) comprising at least one device for delivering and expelling 1 according to the present invention as previously described. Obviously, the delivering machine for infusion beverages according to the present invention can comprise any system traditionally used for operating known machines or any other element that can be normally found in a coffee machine or in any other system for delivering infusion beverages, such as, for example, at least one water tank, at least one pump for moving water, means for heating water and at least one water-delivering duct to the delivering means 15 of the second moving part 7 of the device 1.
