    CAPSULE PACKAGING PROCESS OF FOOD LIQUID PREPARATION AND MACHINE USING SUCH PROCESS
    The present invention relates generally to the field of processes and packaging machines in capsules of liquid food preparations, of the food drink type.
    The present invention relates more particularly to a process for packaging a powdered ingredient preparation, for example ground coffee, in a capsule intended for the production of a liquid food, of the food-drink type, said process comprising: a step of feeding said capsule with a predetermined amount of said preparation, - a step of tamping said preparation in said capsule, - a step of controlling the amount of preparation in said capsule.
    The present invention also relates to a machine adapted for implementing such a method.
    In the field of the packaging of powdered ingredient preparations, for example ground coffee, intended for the production of food drinks, manual processes are known first of all.
    These processes, very well controlled and generally implemented in the hotel and restaurant sector, are particularly well suited to occasional operations for packaging powdered ingredient preparations.
    For example, when the preparation of powdered ingredients is ground coffee, the barista (or "barista" in Italian) perfectly masters the process of grinding coffee beans, dosing and pouring the grounds in a filter, sharpening and compacting said grind in the filter with a compacting pad (or "tamper") to obtain a homogeneous grinding pellet ready for use in a high-pressure brewing machine (known as an espresso machine) ").
    In general, the dosage of the right amount of ground coffee is relatively simple, the barist merely to fill the filter to the brim, which represents about 6 to 8 g of ground coffee
    A suitably leveled and compacted coffee grinding preparation allows a homogeneous extraction of the components, the grinding providing uniform resistance to hot water under high pressure during percolation. If the grind is insufficiently compacted or packaged unevenly, the infusion water causes it to be dispersed in the filter holder, resulting in uneven extraction, shorter percolation time and the production of an espresso coffee. >> of low organoleptic quality. On the contrary, a milling that is too tightly packed results in an increase in the percolation time, thus an over-extraction, which causes a bitter drink.
    In a process of industrialization of this packaging practice, especially since the arrival on the market of "public" devices for high-pressure percolation for the production of coffee drinks of the "espresso" type, the traditional filter has has been replaced by a capsule, usually for single use only. This capsule contains a given dose of coffee, corresponding to obtaining a portion of a drink. It is hermetically sealed with a seal so that it can be transported, distributed and stored under good conditions. When this capsule is inserted into a high-pressure percolation device, it is pierced with a multitude of holes through which hot water is injected. The capsule thus plays a role of filter.
    In this context, processes and industrial machines for packaging such capsules are known. Suitable for the production of capsules in very large quantities and at a very high rate, typically about 600 capsules / minute, these processes are generally complex and the machines are particularly bulky, expensive and delicate to fine-tune and adjust. Subject to the vibrations related to their very high operating rate and to the fouling by grinding residues, in particular during feeding operations of the capsules in grinding and packing of this grind, these machines are of relatively complex maintenance.
    It has been found necessary to develop a reliable and robust intermediate solution between, on the one hand, the traditional manual process and, on the other hand, the bulky and expensive industrial processes and means, making it possible to package a powdered ingredient preparation. semi-industrial manner, typically at a rate of several hundred capsules / hour, in a simple manner and using means of small footprint, without degrading the performance achieved by the aforementioned industrial means in terms of quantity control Precise preparation conditioned in capsule or adversely impact the homogeneity and repeatability of tamping said preparation. The invention therefore aims to provide an answer to the technical problems listed above, and to propose a new process and a new packaging machine for a powdered ingredient preparation in capsule allowing a particularly precise and repeatable control of the amount of preparation packaged in a capsule.
    Another object of the invention is to propose a new process and a new packaging machine in capsule substantially limiting the problems of fouling.
    Another object of the invention is to propose a new process and a new packaging machine in capsules allowing perfect control of the packing of the preparation packaged in a capsule.
    Another object of the invention is to propose a new capsule packaging method that is particularly simple to implement.
    Another object of the invention is to provide a novel capsule packaging machine particularly compact.
    Another object of the invention is to provide a new capsule packaging machine particularly reliable and robust.
    Another object of the invention is to provide a new packaging machine particularly simple and inexpensive to manufacture.
    The objects assigned to the invention are achieved by means of a process for packaging a powdered ingredient preparation, for example ground coffee, in a capsule intended for the preparation of a liquid food, food-drink type, said method comprising: - a step of feeding said capsule with a predetermined quantity of said preparation, - a step of tamping said preparation in said capsule, - a step of controlling the amount of preparation in said capsule said method being characterized in that the tamping step comprises at least two separate tamping operations.

The invention relates to a packaging machine 1, preferably of the semi-industrial type, a preparation of powdered ingredients, for example ground coffee, in a capsule 2 intended for the preparation of a liquid food, of the food-drink type.
    Figures 1 to 8 illustrate a preferred embodiment of such a machine 1 according to the invention. The machine 1, in its preferred variant thus shown in the figures, forms a machine 1 for packaging a preparation of powdered ingredients, in this case ground coffee, in a capsule 2 intended for the preparation of a liquid food, of the food drink type, and more precisely of the "espresso" coffee type.
    Indeed, said capsule 2 is preferably adapted to be inserted into a device for making beverages, and more particularly a high-pressure percolation device for the preparation of coffee drinks type "espresso". As such, said capsule 2 is formed of a body 21, which comprises a cylindrical or frustoconical side wall 22 connected to an internal space 23 for receiving said powdered ingredient preparation. A base 24 closes the smaller diameter end of the gap 23 and a flange 25 extends around the larger diameter end of the wall 22, which forms an opening 26 for filling, said flange 25 protruding radially outwardly from said filling aperture 26. The invention is not however limited to a machine 1 for ground coffee in capsules 2, and may relate to other powdered ingredients, advantageously ingredients for the production of drinks by leaching or percolation, for example milk powder or chocolate powder or a mixture of such powdered ingredients.
    Therefore, said capsule 2 may of course have a different volume configuration, and the means and technical methods described below can be adapted accordingly, without departing from the scope of the invention.
    Moreover, such a capsule 2 may be single-dose or multidose, that is to say have an internal space 23 of a volume capable of containing a quantity of preparation intended for the production of a single portion of a drink given or, on the contrary, of several portions of said drink.
    Such a capsule 2 may also be disposable or reusable after adequate reprocessing. Preferably made of a material intended to be compatible with food contact, it may be indifferently made of metal, for example aluminum, or plastic, for example in a biodegradable plastic based on starch.
    In any case, a capsule 2 adapted to allow the implementation of the packaging method of the invention using the machine 1 of the invention, is made of a material having sufficient intrinsic rigidity for said capsule 2 is not damaged during the implementation of the process, and in particular under the force of a pressing pressure applied to a preparation it contains.
    As illustrated in Figure 1, said machine 1 advantageously comprises a plurality of different technical devices, hereinafter referred to as "stations", each of these devices being intended to allow the realization of a given separate technical operation, relative to a given capsule 2.
    Said machine 1, in its preferred embodiment illustrated in FIG. 1, preferably comprises the following stations and units: a station 3 for dispensing empty and uncapped capsules; a station 4 for preparing preparation of powdered ingredients; a power station; a station 6 for tamping; a control station 7; a sealing station 8; a station 9 for evacuating the capsules; a control unit (not shown).
    These said stations are preferably positioned relative to a conveyor 10, the latter conveying said capsule 2 from one station to another so as to submit sequentially to said capsule 2 to separate technical operations of each of said stations.
    In a particularly advantageous manner, said conveyor 10 consists of a circular turntable 11, preferably driven in a step-by-step fashion, and provided with through-receiving housings 12 intended, as will be explained hereinafter, to receive said capsule 2 to transport it from one station to another.
    Said stations are preferably positioned relative to the periphery of the edge of said plate 11, which makes it possible to confer on said machine 2 a particularly limited volume and footprint on the ground.
    The dispensing station 3 is intended to feed said machine 1 into empty and unsealed 2 capsules. It advantageously comprises a reservoir 31 for storage of empty and unsealed capsules and a means 32 for loading said empty and unsealed capsules 2 into one of said through receiving receptacles 12 formed in said conveyor 10.
    Within the meaning of the invention, "supply" is understood to mean the filling or filling, partial or total, of the internal space 23 of a capsule 2.
    Such sequential operation of the different stations of said machine 2, thus positioned relative to said turntable 11, further allows said machine 2 to reach particularly high rates, typically a rate of 500 to 700 capsules processed per hour.
    The preparation station 4 preparation powder ingredients is advantageously designed so as to allow the realization of a homogeneous powder preparation from one or more ingredients, processed or raw, but preferably dry.
    In the preferred embodiment illustrated in FIG. 1, in which said preparation is ground coffee, said processing station 4 comprises at least one reservoir 41 of ingredients intended to temporarily store said processed or raw ingredients, in this case roasted coffee beans, a means of production (not shown), in this case a means of milling these grains, for example a flat grinder mill.
    According to an important characteristic of the invention, the machine 1 comprises a feed means 51, preferably integrated in the feed station, of the capsule 2 with the preparation of powdered ingredients.
    As illustrated in Figure 3, the means 51 supply is intended to supply said capsule 2 with the preparation of powder ingredients, preferably carried out beforehand by said station 4 of elaboration.
    Preferably, said feed means 51 comprises: - a supply inlet 52 through which the preparation enters the supply means 51, - a supply chamber 53 intended to receive the preparation entering through said inlet 52 supply and provided with an upper orifice 54 and a lower orifice 55 opening on either side of said means 51 for supply, said upper and lower orifices 54 and 55 being substantially identical and positioned opposite one of the another, a supply outlet 56 through which the preparation contained in said chamber 53 leaves said supply means 51 in order to feed said capsule 2.
    Preferably, said supply outlet 56 is formed by said lower orifice 55 of the supply means 51.
    According to the preferred embodiment illustrated in FIGS. 3 and 4, said supply inlet 52 is provided with a feed tube 57, opening on the one hand on one end 58 free, and on the other on said inlet 52 Said free end 58 is preferably intended to be connected to an outlet of the processing station 4 so that the feed tube 57 allows the transfer of the powdered ingredient preparation from the processing station 4. to the feed chamber 53 of the feed station 5.
    Still according to this preferred embodiment, said supply means 5 consists of a body 59 in one piece, obtained for example by molding or machining. Its feed chamber 53 has a substantially cylindrical shape, and opens out on either side of said feed means 5 through the upper orifice 54 and circular lower orifice 55, of diameters identical to that of said feed chamber.
    According to an important characteristic of the invention, the machine comprises a frame 60 and means 61 of tamping, preferably integrated in the station 6 of tamping, of said preparation in the capsule 2.
    As illustrated in Figures 5 and 6, the means 61 tamping is intended to pack the preparation of powdered ingredients which has been previously poured into the capsule 2 through the means 51 supply.
    This means 61 for compacting preferably comprises a compression member 62 mounted movably relative to the frame 60 between: - a compression position in which the compression member 62 is designed to engage in the opening 26 for filling the capsule 2 and exerting a predetermined pressure Ppred on the preparation contained in said capsule 2 and - at least one release position in which the compression member 62 is designed to release said pressure Ppred exerted on the preparation and disengage the opening 26 of filling the capsule 2.
    Said compression member 62 is preferably constituted by a rigid body 63, for example of cylindrical shape, for example made of steel or bronze, and delimited by an outer surface 64, a coupling end 65 and a free end 65 of compression substantially flat.
    The body 63 of said compression member 62 may of course have a shape other than a cylinder. But, in any event, said body 63 of the compression member 62 advantageously has, at least in the vicinity of said free compression end 66, a section complementary to the section of the opening 26 of the capsule, so that that said compression end 66 can cooperate closely with said opening 26 and in particular that said compression member 26 can slide tightly into said capsule 2 from its filling opening 26 and towards its base 24.
    Even more preferably, said section of said body 63 is such that the latter slides tightly, that is to say substantially without play, in said capsule 2 from its filling opening 26 and toward its base 24.
    Said means 61 for tamping also preferably comprises a first actuator 67 slidably mounted relative to the frame 60 between an actuated position in which said first actuator 67 cooperates with the compression member 62 so that the latter occupies its compression position and at least one rest position in which said first actuator 67 recalls the compression member 62 in its release position.
    Preferably, said compression member 62 is slidably mounted relative to the frame 60 along a first sliding axis A-A ', for example in a first guide sleeve 68 fixed relative to the frame 60, whereas said first actuator 67 is slidably mounted relative to the frame 60 along a second axis B-B 'of sliding, said first A-A' and second B-B 'sliding axes being advantageously combined.
    In the preferred embodiment shown in Figures 5 and 6, said compression member 62 is secured by one of its ends to a free end 671 of the first actuator 67, so that the compression member 62 and the first actuator 67 are part of a single unitary room.
    Even more preferably, said first actuator 67 consists of the rod 691 of a first jack 69, for example pneumatic or hydraulic, fixed integrally to the frame 60.
    In addition, said tamping means 61 is preferably configured so as to slide tightly in the feed chamber 53 of said feed means 51, between said upper orifices 54 and a lower orifice 55 of the feed chamber 53. when said compression member 62 moves from its release position to its compression position.
    As illustrated in FIGS. 5 and 6, the compression member 62 of the tamping means 61 thus, when it moves from its release position to its compression position, advantageously contribute to passing said preparation of powdered ingredients contained in said supply chamber 53 through the feed outlet 56 of the feed means 51 towards the filling opening 26 of the capsule 2, while preventing the preparation residues from sticking to the walls of the chamber 53 power supply.
    Such a superimposed configuration of the balancing means 61 and the feed means 51 also contributes more advantageously to reducing the dimensions and the bulk space of the machine 2.
    In the embodiment illustrated in FIG. 1, the feed stations and the tamping station 6 advantageously form one and the same station. However, it remains perfectly conceivable that these stations 5, 6 are on the contrary distinct from each other.
    Preferably, the machine 1 comprises a support device 13 for holding a capsule 2 firmly in position at a first predetermined position Z1 relative to said frame 60, during the implementation of said feeding means 51 and packing 61 .
    This support device 13 is preferably constituted on the one hand by a conveyor 10, preferably of the turntable type, provided with at least one receiving housing 12 passing through the edges 121 of which a rim 25 of said capsule 2 is positioned. when the latter is housed in said receiving housing 12 through.
    In this case, in the embodiment shown in the figures, said conveyor 10 is the conveyor 10 described above, advantageously consisting of the turntable 11 also described above.
    Said support device 13 preferably consists, on the other hand, of a force recovery device 131 intended to come into contact with the capsule 2 so as to counteract the compressive force exerted by the tamping means 61. .
    This force recovery device 131 advantageously comprises a force-absorbing member 132 movably mounted relative to the frame 60 between a support position in which the force-absorbing member 132 is designed to come into contact with the capsule 2. , for example at its base 24, so as to counteract the compressive force exerted by the tamping means 61 and at least one withdrawal position in which the force-absorbing member 132 is designed to cancel the contact with the capsule 2.
    In order to allow optimal support of the capsule 2, in its first predetermined position Z1, and to better take up the compressive force exerted by the tamping means 61, said force-absorbing member 132 is, in particular illustrated in FIG. 5, provided with an upper opening 133, upper edges 134, lateral walls 135 and a bottom 136 delimiting an inner housing 137 of shape substantially complementary to that of the body 21 of said capsule 2.
    This particular configuration makes it possible to prevent a detrimental deformation of the capsule 2 under said compressive force, a deformation which could in particular have the effect of modifying the volume of the internal space 23 and of deforming the rim 25 of the capsule 2. The characteristics mechanical of said capsule 2 would therefore be compromised, potentially leading thereafter to a faulty sealing operation or difficulties in implementation of said capsule 2 in the device for producing drinks in which it is intended to be inserted once energized and sealed.
    In addition, such a configuration makes it possible in the same way to avoid any risk of deformation of the conveyor 10 under said compressive force and in particular to avoid any risk of veiling of the rotating plate 11, which is preferably said conveyor 10.
    Said force recovery device 132 also advantageously comprises a second actuator 14 slidably mounted relative to the frame 60 between an actuated position in which said second actuator 14 cooperates with the force-absorbing member 132 so that the latter occupies its supporting position. and at least one rest position in which said second actuator 14 recalls the force-absorbing member 132 in its retracted position.
    Preferably, said force-absorbing member 132 is slidably mounted relative to the frame 60 along a third axis (C-C ') of sliding, for example in a second guide sleeve 15 fixed relative to the frame 60, while said second actuator 14 is slidably mounted relative to the frame 60 according to a fourth axis (D-D ') of sliding, said third (C-C') and fourth (D-D ') sliding axes being advantageously combined.
    In the preferred embodiment shown in the figures, said force-absorbing member 132 is secured by a coupling end 138, opposite to the upper opening 133, at a free end 141 of the second actuator 14, so that the body 132 of force recovery and the second actuator 14 are part of a single unitary part.
    Even more preferably, said second actuator 14 consists of the rod 161 of a second cylinder 16, for example pneumatic or hydraulic, integrally fixed to the frame 60.
    Advantageously integrated in said station 6 tamping, and in particular fixed integrally to said frame 60, said member 132 of force recovery is preferably positioned opposite the means 61 of tamping, so that said first (A-A ') and third (C-C ') sliding axes are merged.
    According to an important characteristic of the invention, the machine 1 comprises a control means 71, preferentially integrated in the control station 7, of the quantity of preparation in said capsule 2.
    As can be seen in FIG. 6, this control means 71 is intended to control the quantity of powdered ingredient preparation that has been previously poured into the capsule 2 via the feed means 51.
    This means 71 for controlling the amount of preparation preferably comprises: a marker 72 fixedly positioned relative to the compression member 62 at a second predetermined position Z2, and a measuring device 73, for example optical, fixedly secured at frame 60 of the machine at a predetermined third position Z3, and able to measure the distance d between said second predetermined position Z2 of said mark 72 and said third predetermined position Z3 of said measuring device 73.
    As illustrated in particular in FIG. 6, the control medium means 71 is advantageously closely associated with the tamping means 61, so as to further reduce the dimensions and the bulk space of the machine 1.
    Said reference 72 thus consists of a pin 721 fixed to the body 63 of the compression member 62 in said second predetermined position Z2 and protruding from said body 62 to open and slide through a longitudinal slot 681 formed in the wall of FIG. said first guide sleeve 68. This stud 721 advantageously has a plane face 722, which extends in a plane orthogonal to the first axis (A-A ') of sliding.
    Still according to this preferred mode, said measuring device 73 consists, in turn, of a sensor 731 measuring distance and displacement without contact by reflection. Such a sensor 731 generally consists of a laser probe, emitting a laser beam intended to illuminate a target, in this case said flat face 722 of the pin 721, and a photoelectric cell intended to collect the laser beam reflected by said target, so that said measuring device 73 emits an output signal reflecting the distance d between said third predetermined position Z3 of the measuring device Z3 of said second predetermined position Z2 of the marker 72.
    In order to obtain a measurement of the distance d that is as reliable as possible, the measuring device 73, fixed integrally to the frame 60 of the machine at a predetermined third position Z3, for example on the first jack 69, is also advantageously positioned relatively to the stud 721 so that the laser beam emitted by the sensor 731 towards said face 722 of the stud 721 is directed in a direction substantially orthogonal to said face 722.
    Obviously other assemblies and other measurement means 73 may be implemented, without departing from the scope of the invention, to measure this distance d.
    According to the preferred embodiment illustrated in FIG. 1, the feed stations, station 6 for tamping and station 7 for control are thus advantageously grouped together in one and the same station, the means 51 for feeding, the means 61 for tamping and the force-absorbing device 131 being moreover advantageously aligned along the same axis (A-A '), (B-B'), (C-C '), (D-D') vertical.
    This advantageously contributes to making the machine 1 particularly compact.
    The machine 1 also advantageously comprises a support 80 and means 81 for sealing said capsule 2, preferably integrated in the sealing station 8.
    This means 81 of sealing is intended to come close hermetically the opening 26 for filling the capsule 2 with a lid 27, once it filled with powdered ingredient preparation and the latter packed.
    Said sealing means 81 comprises: a module 82 for producing lids, comprising a lidding cutter member 83 equipped with a lidding cutter tool 84 from a strip 85, a module 86 of sealing of the capsules 2 with said cut caps 27.
    Mounted movably relative to said support 80, preferably sliding along a fifth axis (E-E ') of sliding, the cutting member 83 advantageously comprises a tool holder 831, consisting of a body 832 preferably cylindrical, at one end 833 whose cutting section is removably mounted said cutting tool 84.
    This removable assembly advantageously allows to be able to replace said cutting tool 84 when the cutting zone 841 of the latter is damaged, for example when it is blunted.
    Preferably, said cutting tool 84 forms a circular shape punch 84, the cutting zone 841 of this cutting tool 84 extending beyond said cutting end 833 of the tool holder 831. 83 of cutting is preferably configured so as to evolve, by sliding along said fifth axis (E-E ') of sliding relative to the support 80 between: - a cutting position, in which the cutting member 83 is designed to cut said strip 85 to produce a cover 27, and - a neutral position in which the cutting member 83 is designed to release the cut seal 37.
    According to the preferred embodiment shown in particular in FIG. 8, said module for producing lids is fed in belt 85 by a reel system 87 on which are mounted a roll 871 of new tape and a roll 872 of used tape, said 85 band being guided and maintained using guides 88 so as to come opposite the capsule 2, parallel to the opening 26 for filling said capsule 2.
    As shown in the figures, said cutting position advantageously corresponds to a position in which said cutting member 83 is designed so that its cutting tool 84 comes into contact with the band 85 and, while maintaining this contact, comes to cooperate with the capsule 2, by narrow sliding of the cutting tool 84 relative to the rim 25 of said capsule 2, so as to cut in said strip 85 a cover 27 to the dimensions of the opening 26 for filling the capsule 2 and its edge 25.
    In said neutral position, the cutting tool 84 of the cutting member 83 advantageously disengages from the rim 25 of said capsule 2 and is positioned behind the opening 26 for filling the latter, so as to release the operculum 27 thus cut.
    The sealing module 86 comprises a sealing member 89, able to come to press and fix a cap cut by the cap production module 82 on the rim 25 of the cap 2 in order to hermetically seal the filling aperture 26. .
    Said sealing member 89 preferably has a main body 891 formed of a head 892 which is extended by a rod 983. Said head 892 advantageously has a peripheral circular shoulder 894, axially projecting from the upper surface 895 of said head 892, and whose width is substantially identical to the width of said rim 25 of the capsule 2. Thus, the sealing member 89 exerts a plating force on the cut operculum only in the vicinity of said rim 25 of the capsule 2.
    Said sealing module 82 and sealing module 86 are advantageously configured relative to each other so as to enable the production of a lid 27 and the hermetic sealing of the opening 26 for filling a capsule 2 using the latter in a single operation and in a small footprint.
    Indeed, as illustrated in FIG. 7, said body 832 of the tool holder 831 is advantageously hollow, so that said tool holder 831 constitutes a third guide sleeve 834 able to receive said sealing member 89, preferably its stem 893. , and allow sliding movement of the sealing member 89 in said tool holder 831 along a sliding axis coincident with the fifth axis (E-E ') of sliding of the cutting tool 84 relative to the support 80 .
    Even more advantageously, the head 892 of said sealing member 89 is designed and configured to slide tightly in the cutting tool 84 between: - a retracted position in which the base 896 of the head 892 abuts against the cutting end 833 of the cutting member 83, and - an advanced position in which the upper surface 895 of said head 892 is flush with the edge 842 of the cutting zone 841 of the cutting tool 84, said shoulder 894 peripheral the head 892 extending beyond the edge 842 of said cutting zone 841. The sealing member 89 is preferably mounted in the body 832 of the tool holder 831 by means of a compression spring 835, the latter automatically reminding the head 892 of said sealing member 89 in its advanced position when the latter is in its remote position.
    As illustrated in FIG. 7, the sealing means 81 advantageously comprises a third actuator 811, preferably consisting of the rod of a third jack 812, slidably mounted relative to the support 80, preferably along an axis of sliding coinciding with the fifth axis (E-E ') of sliding of the cutting member 83.
    In mechanical connection with the cutting member 83 of the cap production module 82, this third actuator 811 advantageously makes it possible to pass said cutting member 83 into its cutting position when it is in its neutral position and vice versa.
    Because of the particularly advantageous configuration described above of the module 88 for producing lids relative to the sealing module 86, it is understood that said third actuator 811 makes it possible, simultaneously, to pass the head 892 of the body 89 of sealing of its advanced position when it is in its retracted position and vice versa.
    Therefore, when the cutting member 83 moves from its neutral position to its cutting position under the action of the third actuator 811, it carries with it the sealing member 89 until the shoulder 894 of the head 892 of the latter comes to exercise a plating force of the band 85 in contact with the rim 25 of the capsule 2.
    The third actuator 811 continues its action, the cutting member 83 continues to slide towards its cutting position and its cutting tool 84 itself slides against the rim 25 of the capsule 2 so as to cause the cutting of the strip 85 in a cover 27.
    In response, the sealing member 89 is simultaneously sliding from its advanced position to its retracted position, while maintaining its plating force on the rim 25 of the capsule 2 of the lid 27 thus cut.
    Preferably, said sealing means 81 seals said capsule 2 by welding a thermofusible lid 27, cut in a strip 85, for example of plasticized paper, on the rim 25 of said capsule 2.
    In this preferred case, illustrated in particular in FIG. 7, the sealing member 89 advantageously comprises a heating element 897, for example a heating resistor 898, making it possible to raise the temperature of the sealing member 89, in particular to level of its peripheral shoulder 894, at an at least partial melting temperature of said thermofusible lid 27.
    In this way, when the head 892 of the sealing member 89 comes to press the strip 85 in contact with the rim 25 of the capsule 2, the latter advantageously thermally bonds the lid 27 cut in the strip 85 on the rim. 25 of said capsule 2.
    Alternatively, it is quite possible, without departing from the scope of the invention, that the sealing of the capsule 2 is made otherwise than by welding a hot melt seal. It is indeed perfectly conceivable that this seal is made by gluing, the rim of said capsule 2 being previously coated with an adhesive. In this case, the means 89 for sealing would be without a heating element 897.
    This means 89 for sealing said capsule 2 is, according to the embodiment shown in FIG. 1, advantageously integrated with the sealing station 8 of the machine 1.
    However, said sealing means 89, considered independently of the machine 1 and in particular the means 61 for tamping, could constitute as such an invention in its own right.
    In this preferred embodiment, illustrated in the figures, in which said sealing means 81 is integrated in the sealing station 8 of the machine 1, the through housing 12 formed in the conveyor 10 is preferably provided with a ring 122 designed and configured so that when the cutting zone 841 of the cutting tool 84 comes to slide closely between the inner surface of this ring 122 and the rim 25 of the capsule 2.
    The presence of this ring 122 advantageously allows to obtain a clean and clean cut of the cover 27, limiting the risk of tearing of the strip 85 under the force of the cutting tool 84.
    The evacuation station 9 advantageously comprises: a first substation 91, intended to allow the evacuation of "non-conforming" capsules 2, designed to allow the evacuation to the first receptacle of scrap of the capsules 2 fed, packed and seals containing a measured amount of preparation Qcaic differing from said predetermined quantity Qpred by a percentage excluded from a fixed tolerance range; a second substation 92, intended to allow the evacuation of "conforming" capsules, designed to allow the evacuation to a second container of the filled, packed and sealed capsules 2 containing a quantity Qcaic of measured preparation which does not differ from said predetermined quantity ΟρΓβει according to a percentage excluded from a fixed tolerance range.
    According to an important characteristic of the invention, the machine 1 comprises control means (not shown).
    According to a preferred embodiment of the invention, said control means are advantageously integrated into a control unit (not shown) which preferably comprises said machine 1, said control unit advantageously comprising a set of electronic and computer means, in particular by example a programmable controller, calculation means and a memory.
    In functional connection at least with the means 61 of tamping, these control means are able to control said means 61 for tamping so that it performs at least two tamping operations.
    In other words, said control means are designed to control the operation of said means 61 for tamping the machine 2, relative to the same capsule 2 given, so that the means 61 for tamping submits the preparation of powdered ingredients poured into said capsule 2 to a cycle of at least two operations E41, E42 separate tamping, consecutive or not.
    Preferably, these control means are in operative connection with each of the stations and devices described above, so as to also advantageously allow: the sequential displacement of the conveyor 10, in order to allow the sequential displacement of said capsule 2; one of said stations to another, from the distribution station 3 to the evacuation station 9; the sequential control of each of said stations in a step adjusted on the step of sequential displacement of the conveyor 10, so that said stations realize, in turn, in relation with a given capsule 2, in a predefined order, the operation for which each of them is conceived; the control of the production parameters of said preparation of powdered ingredients by the processing station 4, for example in the case of a preparation of ground coffee, a check of the distance of the grinding wheels of a mill, and therefore the fineness of the grind, and the duration of operation, so the amount of ground coffee; the reception of the output signal from the control means 71, which reflects the distance c / which separates said third predetermined position Z3 from the device 73 for measuring said second predetermined position Z2 of the marker 72, the calculation of the quantity Qcaic of preparation contained in the capsule 2 after tamping and the piloting, therefore, of one or other 91.92 evacuation substations.
    Said control unit (not shown) furthermore advantageously comprises a Human Machine Interface and data input / output peripherals in order, for example, to allow a user to pre-configure and modify known operating parameters of one or the other of said stations, including the predetermined Qpred quantity of preparation, the predetermined pressure Ppred tamping, in particular to take into account a change in nature of the ingredients of said preparation.
    Through this Man-Machine Interface, the user can also advantageously modulate the general rate of said machine 2 or access logged data relating to the operation of said machine 1. The invention also relates to a method of packaging a preparation of powdered ingredients, for example ground coffee, in a capsule 2 intended for the preparation of a liquid food, of the food drink type.
    According to an important characteristic of the invention, said method comprises: a step E3 supplying said capsule 2 with a predetermined quantity Qpred of said preparation, a step E4 of packing said preparation in said capsule 2, a step E5 control of the amount of preparation in said capsule 2.
    Said feeding step E3 aims at feeding an empty capsule 2 with a predetermined quantity Qpred of said powdered ingredient preparation.
    Although it can perfectly be carried out manually from a given powdered ingredient preparation, this step E3 is advantageously carried out using the feed station 5 of the machine 1 previously described.
    During said feeding step E3, it is thus possible: - to position, by means of the conveyor 10, an empty capsule 2 under the feed means 51, so that the filling opening 26 of said capsule 2 comes flush with the supply outlet 56 of said supply means 51, the filling opening 26 of said capsule 2 being parallel to the supply outlet 56 of said supply means 51; performing a feeding operation E31, E32, consisting in: pouring into the feed chamber 53, via the feed inlet 52 of said feeding means 51, the predetermined quantity Qpred of preparation of powdered ingredients , preferably carried out beforehand by said processing station 4 during an elaboration step E2 (explained hereinafter), then supplying said capsule 2, via the feed outlet 56 of said feed means 51, with said predetermined Qpred quantity of powdered ingredient preparation contained in said feed chamber 53.
    For example, the density of a coffee ground may be different from one coffee variety to another or depending on the roasting and milling parameters of the coffee beans, with a predetermined Qpred quantity of ground coffee identical, the volume occupied by the milling in the capsule 2 may thus vary.
    Thus, said predetermined quantity Qpred preparation, set by the user, is expressed in mass units. In the example of a single-dose capsule intended for the preparation of an "espresso" coffee, it is thus advantageously between 4.5 and 6.5 g of ground coffee and, even more advantageously, between 4 and , 8 and 5.2 g.
    Following this feeding step E3, a step E4 of compacting said preparation in said capsule 2 is carried out.
    This packing step E4 is a particularly important step of said packaging process and even more particularly in the example case in which said powdered ingredient preparation is ground coffee. The successful completion of this step will depend on the precise control of the quantity of coffee packaged in the capsule 2, the sealing of the sealing of the latter, the limitation of the fouling of the machine 1, as well as the organoleptic qualities of the liquid food that can be obtained using this capsule 2 and its contents.
    According to an important characteristic of the invention, this packing step E4 comprises at least two distinct operations E41, E42 for tamping.
    In other words, the preparation contained in the capsule 2 is not compacted once as is done conventionally, but is compacted at least twice, during operations E41, E42 separate tamping belonging to a same step E4 tamping, immediately consecutive to each other or not.
    Preferably, the feed step E3, introduced above, comprises at least two distinct partial feed operations E31, E32, at the end of which the latter of said capsule 2 contains said predetermined quantity Qpred of preparation.
    The capsule 2 is thus fed, according to this preferred embodiment, fractionally, repeating at least twice the feeding operation E31 described above by pouring each operation only a fraction of said predetermined Qpred quantity of preparation in said capsule 2 via said feeding means 51. At the end of the last of these operations E31, partial supply E32, said capsule 2 then contains said predetermined Qpred quantity of preparation.
    Even more preferably, each said feeding operation E31, E32 is followed by a pressing operation E41, E42.
    It has indeed been observed that such a fractionation and such sequencing of the steps E3, E4 and operations E31, E32, E41, E42 feeding and tamping advantageously avoids any overflow of preparation on the edge of the capsule 2 under the effect of the tamping force.
    Such an overflow, in addition to the fact that it would be a source of loss of preparation and fouling of the machine 1, could compromise the sealing of the sealing of said capsule 2 during the sealing step described in detail here. -after.
    Of course, it is quite possible to divide the supply step E3 into more than two distinct operations E31, E32, for example into n distinct operations E31, E32,..., E3n. In this case, said packing step E4 then preferably comprises n distinct operations E41, E42,..., E4n.
    Said pressing operations E41, E42 are preferably carried out by mechanical compression of the preparation in the capsule.
    Even more preferably said mechanical compression is performed so that the compressive force applied to the preparation in the capsule 2 is homogeneous and substantially identical for each operation E41, E42 tamping.
    Said preparation is thus compressed mechanically against the bottom of said capsule 2 several times, preferably applying to it each time the same pressure Ppred. The latter is advantageously between 9 and 11 kg and even more advantageously is substantially equal to 11 kg.
    It has indeed been advantageously observed that the fractionation and sequencing of the steps E3, E4 and operations E31, E32, E41, E42 feeding and tamping as described above, coupled with such a method of mechanical compression generates particularly beneficial technical effects on the packaging of said preparation.
    This makes it possible, in fact, to obtain a more homogeneous and more regular packing of said preparation in the capsule 2, and from there a better control of the Qcaic quantity of preparation actually contained in the capsule 2.
    If this step E4 of tamping said preparation in said capsule 2 can itself also be carried out manually, it is advantageously implemented using the means 61 for tamping, preferentially integrated in the station 6 of tamping, previously described. In particular, this mechanical compression is advantageously provided by means of the compression member 62 of said tamping means 61.
    According to this preferred embodiment, one successively comes: - position, using the conveyor 10, said capsule 2 from Step E3, right above the member 132 of force recovery of the device 13 of force recovery and according to the third axis (C-C ') of said sliding device 13 of force recovery, the opening 26 of said capsule 2 filling advantageously extending parallel to the free end 66 compression said compression member 62; - Maneuvering the second actuator 14 of the force-absorbing device 13 to slide it relative to the frame 60 along said fourth axis (D-D ') of sliding of its rest position in which said second actuator 14 recalls the member 132 of recovery of effort in its retracted position to its actuated position in which said second actuator 14 cooperates with the body 132 of force recovery for the latter to occupy its support position, wherein said body 132 of force recovery is designed to come into contact with the capsule 2 so as to counteract the compressive force exerted by the tamping means 61, then - carry out at least two operations E41, E42 tamping, consisting of: o operate the first actuator 67 of the means 61 of tamping to slide relative to the frame 60 according to said second axis (B-B ') of sliding of its rest position in which said first actuator 67 recalls the compression member 62 in its release position to its actuated position in which said first actuator 67 cooperates with the compression member 62 for the latter to occupy its compression position in which said compression member 62 is designed to engage in the opening 26 for filling the capsule 2 and exert a predetermined pressure Ppred on the preparation contained in said capsule 2, then o apply to the preparation contained in said capsule 2, with the aid of said compression member 62, a compressive force until a compression pressure equal to said predetermined pressure Ppred, o maneuver the first actuator 67 of the tamping means 61 to slide relative to the frame 60 along said second axis (B-B ') of sliding its position actuated at a rest position in which said first actuator 67 recalls the compression member 62 in its position of release, in which said compression member 62 is designed to release the pressure exerted on the preparation and to disengage from the opening 26 for filling the capsule 2, - to maneuver the second actuator 14 of the device 131 for the recovery of force for the sliding relative to the frame 60 along said fourth axis (D-D ') of sliding of its actuated position to a rest position in which said second actuator 14 recalls the body 132 of force recovery in its retracted position, in which said force-absorbing member 132 is designed to cancel the contact with the capsule 2.
    The preferential implementation of the packing step E4 with the aid of said tamping means 61 also advantageously makes it possible to obtain homogeneous packing without first having to carry out a leveling operation, ie that is, without having to evenly distribute the preparation in the capsule 2 before proceeding with the tamping.
    This beneficial effect is obtained by the combination of said fractionation and the particular sequencing of the steps E3, E4 and operations E31, E32, E41, E42 feeding and tamping, and the design of the compression member 62 of said means 61 of tamping, which has, as previously described, at least in the vicinity of its end substantially free flat compression end 66, a complementary section to the section of the opening 26 of the capsule, so that said compression member 62 can slide tightly in the opening of said capsule 2.
    Alternatively, it is perfectly conceivable, without departing from the scope of the invention, to carry out said operations E41, E42 other than by a mechanical compression technique, for example, by a vibration tamping technique. In such a case, the tamping means 61 and its method of implementation would therefore be adapted accordingly.
    Said step E5 for controlling the quantity Qcaic of preparation in said capsule 2 is preferably carried out consecutively to each of the operations E41, E42 for tamping.
    In any event, said preparation quantity control step E5 is performed at least consecutively to the last of the pressing operations E41, E42.
    This control step E5 is advantageously implemented using control means 71 and control means, preferably preferably integrated with said control station 7 and control unit (not shown) previously described.
    It is thus advantageously carried out simultaneously with the packing step E4 described above, and more precisely at the moment when the compression force applied by the tamping means 61 on the preparation contained in the capsule 2 reaches said predetermined pressure Ppred.
    In this control step E5, the Qcaic quantity of preparation contained in the capsule 2 is then preferably calculated after tamping from: the distance d between said predetermined second position Z2 of said mark 72 and said third predetermined position Z3 of said device 73 of measuring, as measured and raised by the output signal of said measuring device 73, and a certain number of known and pre-parameterized data in the control means of the control unit: the volume of the space 23 inside the capsule 2, the area of the opening 26 for filling the capsule 2, the first predetermined position Z1 of the capsule 2, the second predetermined position Z2 of the mark 72, the third position Z3 predetermined of the device 73 of measure, and the density of the powdered ingredient preparation considered.
    This Qcaic quantity is then compared with the predetermined Qpred quantity of preparation, preferably by applying a fixed tolerance interval, for example of plus or minus 10%.
    If the amount Qcaic of preparation contained in the capsule 2 differs from said predetermined quantity Qpred according to a percentage included in this fixed tolerance interval, then the capsule 2 is considered to be "compliant". Otherwise, capsule 2 will be considered "non-compliant".
    This particularly simple and robust mode of determination of the quantity Qcaic contained in the capsule 2 is made possible and particularly accurate and repeatable over time thanks to the homogeneity of the packing obtained by the implementation of the feeding steps E3 and E4 of tamping the process of the invention.
    Said packaging method also preferably comprises the following steps, consecutive to said feeding step E3, packing step E4 and control step E5: a sealing step E6, advantageously carried out using the sealing means 81 , preferentially integrated in said sealing station 8, previously described, during which there is produced a lid 27 from a strip 85 and fix it on the rim 25 of a capsule 2 fed and packed and so to hermetically sealing the opening 26 of filling; a step E7 of evacuation, advantageously implemented using the evacuation station 9 described above, during which we come to realize: o either a substep E71, advantageously implemented using of the first substation 91 previously described, in which said capsule 2 fed, compacted and sealed to the first receptacle of refuse is discharged if the control unit returns information indicating that the quantity Qcaic of preparation contained in the capsule 2 differs said predetermined quantity Qpred according to a percentage excluded from a fixed tolerance range; o is a substep E72, advantageously implemented using the second substation 92 described above, wherein is evacuated to a second container said capsule 2 fed, packed and sealed if the control unit returns a information indicating that the Qcaic amount of preparation contained in the capsule 2 does not differ from said predetermined amount ΟρΓβει according to an included percentage of a fixed tolerance range.
    Finally, the method and the machine 1 allow the packaging of a powdered ingredient preparation, in particular ground coffee, in capsules in a particularly efficient and reliable manner, ensuring a very high accuracy in the amount of preparation put into capsules , a perfect homogeneity of the packing of the preparation in the capsules, all in a limited space suitable for a semi-industrial use.
