- FIGs 1 a and 1 b schematically show capsules C for producing beverages that can be packaged by means of the machine and/or the method according to the present invention.
- the capsules C can, for example, contain soluble and/or infusion products like, for example, ground coffee, milk and/or powdered cocoa, tea leaves or similar.
- the capsule shown in figure 1 a is open and comprises a capsule body 16 comprising a capsule bottom 17 and a side wall that define the containment volume of the capsule. On the opposite side to the capsule bottom 17, the capsule C is open so as, for example, to be able to insert the product from which the desired beverage is obtained.
- the side wall of the capsule comprises a projecting edge that defines a surface S on the opposite side to the capsule bottom 17.
- the projecting edge surrounds and also defines the opening G of the capsule.
- the capsule C shown in figure 1a is frusto-conical in shape, so that the surface S is circular, but alternatively the capsule C and therefore the surface S can have any other shape, for example polygonal.
- Figure 1b shows the capsule C of figure 1a closed by means of a closing element 5.

- the closing element 5 can be made of aluminium.
- the closing element 5 can for example be a filtering element, for example filter paper or similar. In this case, the closing element 5 prevents the product contained in the capsule C from coming out from the capsule, but allows for example the passage of gas and/or liquid through its surface.
- Figure 2 schematically illustrates a 3D view of a machine 1 for packaging capsules C for producing beverages according to an embodiment of the present invention.
- the machine 1 comprises a carousel 2 adapted for transporting the capsules C, housed on the carousel 2 in suitable seats 8, along a circular direction, during the packaging steps.
- the various operative stations of the machine 1 are positioned so as to operate on the capsules C housed in the seats 8 of the carousel 2.
- the circular direction of advancement of the machine is in the anti-clockwise direction and is schematically indicated by the arrow F.
- the carousel 2 rotates around its centre O.
- the rotation of the carousel 2 can, for example, be actuated by a first motor 12.
- the carousel 2 rotates in the anti-clockwise direction along the direction F.
- Figure 2 shows that the seats 8 of the capsules C are arranged on the carousel 2 on two concentric circles A and B centred on the centre O of the carousel 2.
- the seats 8 can be arranged on the carousel 2 also on more than two concentric circles centred on the centre O of the carousel, for example on 3, 4, 5 or on a greater number of concentric circles.
- the seats 8 can be arranged on the two or more concentric circles in phase.
- the seats 8 can be arranged on the carousel 2 so that each n-th capsule CA(n) on the circle A, for example the outermost one, corresponds to the n-th capsule CB(n) on the circle B, for example the innermost one, adjacent to the n-th capsule CA(n).
- the corresponding seats 8, i.e. for the capsules CA(n) and CB(n), on the two concentric circles, respectively, are, in this way, located substantially along the same radius of the carousel 2 as shown in figure 3 or in figure 4 .
- the seats 8 are arranged side-by-side in pairs along the perimeter of the carousel 2 so as to form two concentric circles, an outer one A, i.e. with larger diameter, and an inner one B, i.e. with a smaller diameter, and so that the two corresponding seats of the same pair belonging to the two distinct circles are arranged substantially along the same radius of the carousel 2.
- This characteristic of the seats arranged in phase on the various circles can also be implemented with a number greater than two of concentric circles.
- the seats 8 can be arranged on the two or more concentric circles out of phase, as shown schematically in figure 5 .
- the seats 8 are side-by-side in pairs along the perimeter of the carousel 2 so as to form two concentric circles, an outer one A, i.e. with a larger diameter, and an inner one B, i.e.
- the shape of the seats 8 shown in the figures is circular, but they can be of any shape, for example polygonal, compatible with the shape of the capsules C to be packaged.
- the machine 1 shown in figure 2 also comprises a transportation device 3 for transporting a film 4, at least partially along a linear sliding direction X that lies on a plane parallel to the carousel 2.
- the expression "plane parallel to the carousel 2" means a plane parallel to the plane defined by the upper surface of the carousel 2 on which the seats 8 for the capsules are arranged.
- the device 3 can, for example, comprise a roller pulling system for unwinding the film 4 from an unwinding reel 25 to a winding reel 26. In the embodiment shown in figure 2 , the film 4 moves in the direction indicated by the arrow I.
- the transportation device 3 can comprise one or more pulling rollers 23 and one or more rollers that rotate idly
- the pulling rollers 23 are the rollers that actuate the movement of the film 4.
- the rollers that rotate idly 24 are rollers that rotate freely under the pulling action of the film 4 due to the action of the pulling rollers 23.
- the pulling roller 23 can be actuated by a second motor 13 of the machine 2 so as to unwind the film 4 from the unwinding reel 25 and to wind it back up into the winding reel 26.
- the motor 12 that sets the carousel 2 in motion is the same one that sets the transportation device 3 in motion.
- the rollers that rotate idly 24 can be arranged so as to define the path of the film 4 from the unwinding reel 25 to the winding reel 26.
- the system can comprise a first roller that rotates idly 24a and a second roller that rotate idly 24b arranged substantially on the same level so as to define at least one section of the path of the film 4 parallel to the plane of the carousel 2. In figure 2 this section is the section between the roller 24a and the roller 24b.
- the film 4 is preferably made of flexible material.
- the film 4 can be made of aluminium, paper, filter paper, multi-layer materials, impermeable materials, filtering materials, or similar.
- the film 4 comprises a first edge 9 and a second edge 10 that, in the section of path parallel to the carousel 2, are parallel to the sliding direction X.
- first edge 9 is meant to indicate the edge that, in this section of path, is furthest from the centre O of the carousel 2 with respect to the second edge 10, which, on the other hand, is closer to the centre O thereof.
- the relative position of the carousel 2 and of the film 4 in the section of path parallel to the carousel 2 can vary according to alternative embodiments of the present invention.
- the film 4 can at least partially or completely overlap the carousel 2.
- the film 4, in this section of its path in which it slides parallel to the carousel 2 may not overlap the carousel itself but slides laterally with respect to the carousel 2.
- Figures 2 , 3 and 5 show configurations in which the film 4 completely overlaps the carousel 2 in the section of path in which it slides parallel to the carousel 2.
- the transportation device 3 of the machine 1 is configured so that, during transportation, the film 4 overlaps the carousel 2 so that the first edge 9 of the film 4 coincides with a line parallel and close to the tangent to the carousel 2 parallel to the sliding direction X.
- the first edge 9 of the film 4 coincides with a line intersecting the carousel 2, parallel to the tangent to the carousel 2 parallel to the direction X.
- the transportation device 3 is configured so that, during transportation along the sliding direction X parallel to the carousel 2, the film 4 is arranged so that the second edge 10 is a distance from the centre O of the carousel 2 greater than the radius R of the carousel 2, so that the film 4 does not overlap the carousel 2. In this case, the film 4 slides laterally with respect to the carousel 2.
- the machine 1 also comprises cutting means 11, adapted for cutting closing elements 5, for closing the capsules C, from the film 4.
- the cutting means 11 can for example comprise blade shearing systems, toothed blade shearing systems, die punch or laser cutter. As shown in the figures, the cutting means 11 are configured so as to cut the closing elements 5 from the film 4 in the section in which the film 4 slides along the sliding direction X parallel to the carousel 2. When the cutting means 11 cut the closing elements 5 from the film 4 imprints for cutting the film 4 are made.
- the cutting means can comprise first cutting means 111 for a first row 71 of imprints of the cutting 6 on the film 4 and second cutting means 11II for a second row 711 of imprints of the cutting 6 on the film 4 (see for example figure 7 ).
- Figures 6a and 6b schematically show the imprints of the cutting of the closing elements in a film, respectively according to the state of the art and according to the present invention.
- the cutting means 11 are adapted for cutting the closing elements 5 so that the imprints 6 of the cutting of the closing elements 5 on the film 4 are arranged along two or more parallel rows, i.e. along at least one first row 7I and a second row 7II.
- the two rows 71 and 7II are also parallel to the sliding direction X.
- the two rows 7I and 7II are offset, so that the space occupied by two imprints 6 that are mutually adjacent and belong to the two distinct rows 71 and 7II, respectively, measured along the direction Y perpendicular to the sliding direction X, is less than or equal to the sum of the dimensions of each of the adjacent imprints 6, measured individually along the same direction Y.
- two imprints 6 of the cutting of the closing elements 5 that are mutually adjacent and belong to the two distinct rows 71 and 7II, respectively can be arranged along a direction E forming an angle ⁇ comprised between 35° and 55°, preferably between 40° and 50°, preferably 45°, with respect to the sliding direction X of the film 4.
- the cutting means 11 are adapted for cutting the closing elements 5 in the section in which the film 4 slides parallel to the carousel 2 along the sliding direction X so that the imprints 6 of the cutting of the closing elements 5 on the film 4 are arranged along two or more rows that are parallel to each other and offset, so that the space occupied by the two or more imprints 6 that are mutually adjacent and belong to the two or more distinct rows, respectively, measured along the direction Y perpendicular to the sliding direction X, is less than or equal to the sum of the dimensions of each of the adjacent imprints 6 measured individually along said same direction Y.
- the distribution of the imprints of the cutting on the film 4 is optimised so as to minimise the amount of film 4 not used to form the closing elements 5.
- the closing elements 5a are cut along parallel rows that are not offset.
- the spatial arrangement of the imprints 6a is such that the unused space between them is very wide and consequently the material of the film that is wasted is high.
- a further advantage of the optimised arrangement of the imprints 6 of the cutting of the closing elements 5 on the film 4 according to the present invention is that of allowing a film 4 to be used having a smaller width (i.e. dimension along the direction Y) with respect to the case in which the imprints 6 are arranged along parallel rows that are not offset to cut closing elements 5 having the same dimensions. This further reduces the amount of material of film 4 required.
- the imprints 6 can be circular in shape, as shown in figure 6b , in the case in which the surface S to be closed of the capsule C is circular.
- the imprints can be of any other shape, for example polygonal, compatible with the shape of the surface S of the capsule C to be closed.
- the imprints 6 are circular in shape with diameter D, they are arranged on the film 4 so that the lateral distance, i.e. measured along the direction Y, between the centres of adjacent imprints 6 belonging to different rows 7I and 7II, is less than or equal to the diameter D of a single imprint 6.
- the cutting means 11 can be arranged so as to cut closing elements 5 not adjacent to one another. If for example a first cutting means 11I cuts the n-th closing element 5I(n) of the row 71, a second cutting means 11II can be arranged so as to cut the (n+1)-th closing element 5II(n+1) of the row 7II and not the n-th closing element 5II(n) of the row 7II. Cutting means 11 arranged so as to cut closing elements 5 that are mutually adjacent, indeed, would have to be distanced apart, due to the bulk thereof, with the consequent increase in distance of the imprints 6 of the closing elements 5 on the film 4 and thus an increase in material waste.
- the transportation device 3 is configured so that the film 4 overlaps the carousel 2, the cutting means 11 arranged so as to cut closing elements 5 that are not adjacent to one another are also arranged so as to cut closing elements 5 that are applied to capsules C that are not adjacent to one another.
- the second cutting means 1111 cuts the (n+1)-th closing element 5II(n+1) of the row 7II, for the capsule CB(n+1) on the inner concentric circle B and not the n-th closing element 5II(n) of the row 7II, for the capsule CB(n) adjacent to the capsule CA(n).
- the closing means 21 are configured to apply the closing elements 5 to the capsules C when the capsules C are housed on the carousel 2.
- the closing means can comprise first closing means 211 for a first row A of seats 8 of capsules C on the carousel 2 and second cutting means 1111 for a second row B of seats 8 of capsules C on the carousel 2 (see for example figure 7 ).
- the closing means 5 are thermo-welded to the capsules by the closing means 21.
- the closing means 21 can thus comprise welding means, for example thermowelders.
- the closing means 21 are at the cutting means 11.
- the first closing means 211 are at the first cutting means 11I and the second closing means 2111 are at the second cutting means 11II.
- the closing means 5 can be cut from the film 4 and applied to the capsules C in a single operation.
- the shape of the cutting means 11 and of the closing means 21 can be any one that is compatible with the shape of the surface S of the capsule C to be closed.
- the closing means 21 can be arranged so as to apply the closing elements 5 to capsules C that are not adjacent to one another in an analogous manner to what is explained above with reference to the cutting means. If for example the first closing means 211 apply a closing element 5 to the capsule CA(n) on the outermost concentric circle A, the second welding means 21II are positioned to apply a closing element 5 to the capsule CB(n+1) on the inner concentric circle B and not to the capsule CB(n) adjacent to the capsule CA(n).
- the spatial arrangement of the imprints 6 on the film 4 corresponds to the spatial arrangement of the seats 8 of the capsules C on the carousel 2. More specifically, the seats 8 of the capsules C are arranged so as to overlap the imprints 6 on the film 4 in the direction Y in the point of tangency between the carousel 2 and the first edge 9 of the film 4. In this way, the closing elements 5 can be cut and applied to the capsule C in a single operation. It should also be noted that in this case the angular speed with which the carousel 2 rotates is synchronous with the speed with which the film 4 slides, so that as the film 4 slides, the capsules C in the seats 8 suitably rotate.
- the spatial arrangement of the imprints 6 on the film 4 may not correspond to the spatial arrangement of the seats 8 of the capsules C on the carousel 2 even if in the figures this correspondence is shown.
- the closing elements 5 are first cut from the film 4 and are then transported to the seats 8 to be applied to the capsules C to close them. In this transportation step it is possible to correct any discrepancy between the spatial arrangement of the imprints 6 on the film 4 and the spatial arrangement of the seats 8 on the carousel 2.
- the machine 1 according to the present invention can also comprise transportation means for transporting onto the carousel 2 the open capsules C that must be packaged and for positioning them in the seats 8 of the carousel 2.

- one of the two dosers is further upstream in the direction of rotation of the carousel with respect to the second.
- the system can comprise different numbers of dosers, for example the system can comprise a single doser with many outlets, one for each of the circles of seats of the carousel. Alternatively, the system can comprise as many dosers as there are circles of seats of the carousel.
- An example of the positioning of the dosers 20 in the architecture of the machine 1 is shown schematically in figure 2 .
- the dosers can be arranged between the transportation means of the capsules and the closing means along the direction F of advancement of the machine.
- Figure 10 shows that the machine 1 according to the present invention can further comprise extractor means 22, for discharging the capsules C from the carousel 2, once they have been closed with the closing elements 5.
- the extractors 22 preferably comprise suction cups, adapted for hooking the capsules C and removing them suitably from their seats 8.
- the suction cups can for example grip onto the closing elements 5 of the capsules.
- An example of positioning of the extractor means 22 in the architecture of the machine 1 is shown schematically in figure 2 .
- the extractor means can be arranged between the closing means and the transportation means of the capsules along the direction F of advancement of the machine.
- the machine 1 shown in figure 2 thus comprises a carousel 2 comprising seats 8 for the capsules C so as to transport the capsules along a circular direction during packaging, transportation means 14 for transporting open capsules towards the carousel 2 and for inserting them in the seats 8 of the carousel 2, a transportation device 3 for transporting a film 4 along a linear sliding direction X that lies on a plane parallel to the carousel, cutting means 11 for cutting closing elements 5 from the film in the section in which it slides along the linear sliding direction X and closing means 21 configured to apply the closing elements 5 to the capsules C when the capsules are housed on the carousel 2, wherein the cutting means 11 are adapted for cutting the closing elements 5 so that the imprints 6 of the cutting of the closing elements 5 on the film 4 are arranged along two or more rows 7 that are parallel to each other and offset, so that the space occupied by two or more imprints 6 that are mutually adjacent and belong to the two or more distinct rows 7, respectively, measured along the direction Y perpendicular

Description
- The present invention concerns the field of machines for packaging capsules for producing beverages. More specifically, the present invention concerns the field of machines for simultaneously closing a plurality of capsules for producing beverages by means of closing elements cut from a film.
- In the state of the art different types of machines for packaging, more specifically for simultaneously closing, a plurality of capsules are known. These machines generally foresee cutting of closing elements, from a film of suitable material, which are applied to the capsules to close them.
- Known machines do, however, have some drawbacks. Often, the capsules to be closed are transported on tracks that are parallel to one another and not offset. Often, in these cases, the closing elements, which are applied to the capsules to close them, are also cut from the film of suitable material, which moves on a plane parallel to the transportation plane of the capsules and in the same direction, at the capsules themselves, and thus along parallel rows, which are not offset. In this way, the arrangement of the closing elements on the film is such that the waste of material from which the film is made is very high. This clearly causes in increase in production costs.
- Document
WO2011/039709A2 discloses a machine according to the preamble ofclaim 1. - In order to avoid the problem just quoted, many known machines have adopted the solution of tilting the sliding direction of the film from which the closing elements are cut with respect to the direction in which the capsules are transported. In this way, the arrangement of the closing elements on the film is still such as to correspond to the arrangement of the capsules, but the material waste is reduced since the closing elements are arranged on parallel rows, but offset from one another. In this case, however, known machines have the drawback of being very bulky.
- Therefore, the purpose of the present invention is to at least partially solve the aforementioned problems.
- More specifically, the purpose of the present invention is to provide a machine for packaging capsules that wastes little material to make the closing elements and that is compact and efficient.
- The present invention is based on the idea of making a machine of the type with a carousel for simultaneously packaging a plurality of capsules for producing beverages in which the capsules are transported on a carousel during the packaging steps and in which the imprints of the cutting of the closing elements on the film are arranged along two or more rows that are parallel to each other and offset. In this way, it is possible to use a compact machine and to avoid needless material waste.
- According to an embodiment of the present invention a machine for simultaneously packaging a plurality of capsules for producing beverages, for example espresso is provided, comprising a carousel, adapted for transporting capsules along a circular direction during packaging, wherein the capsules are housed on the carousel in suitable seats, and a transportation device for transporting a film along a linear sliding direction, wherein the machine also comprises cutting means adapted for cutting closing elements, to close a surface of the capsules, from the film wherein the sliding direction of the film lies on a plane parallel to the carousel and wherein the cutting means are adapted for cutting the closing elements so that the imprints of the cutting of the closing elements on the film are arranged along two or more rows that are parallel to one another and offset, so that the space occupied by two or more imprints that are mutually adjacent and belong to two or more distinct rows, respectively, measured along the direction perpendicular to the sliding direction, is less than or equal to the sum of the dimensions of each of the adjacent imprints measured individually along said same direction and wherein the machine further comprises closing means configured to apply the closing elements to the capsules when the capsules are housed on the carousel. In this way, it is ensured both that the machine is compact thanks to the use of the carousel to transport capsules during the packaging steps, and that the use of the film from which the closing elements are cut is optimised, substantially decreasing the material waste and thus lowering the production costs. The expression "transportation of the capsules along a circular direction during packaging" means that the capsules are transported by the carousel along the circular direction of advancement of the machine so as to carry out the various packaging steps of the capsules while the capsules are housed on the carousel. In other words, the carousel, with its rotation in the circular direction of advancement of the machine, makes it possible to bring the capsules to the various operative stations of the machine so as to carry out the packaging of the capsules while the capsules are housed on the carousel. The expression "plane parallel to the carousel" means a plane parallel to the plane defined by the upper surface of the carousel, i.e. the surface, generally circular in shape, on which the seats for housing the capsules are made.
- According to an embodiment of the present invention a machine for simultaneously packaging a plurality of capsules for producing beverages, for example espresso, is made, comprising a carousel comprising seats for the capsules so as to transport the capsules along a circular direction during packaging, transportation means for transporting capsules open towards the carousel and for inserting them in the seats of the carousel, a transportation device for transporting a film along a linear sliding direction that lies on a plane parallel to the carousel, cutting means for cutting closing elements from the film in the section in which it slides along the linear sliding direction and closing means configured to apply the closing elements to the capsules when the capsules are housed on the carousel, wherein the cutting means are adapted for cutting the closing elements so that the imprints of the cutting of the closing elements on the film are arranged along two or more rows that are parallel to each other and offset, so that the space occupied by two or more imprints that are mutually adjacent and belong to the two or more distinct rows, respectively, measured along la direction perpendicular to the sliding direction, is less than or equal to the sum of the dimensions of each of the adjacent imprints measured individually along the same direction perpendicular to the sliding direction.

- According to a further embodiment of the present invention, a machine is provided in which the transportation device of the film is configured so that, during the transportation along the linear sliding direction, the film at least partially overlaps the carousel. For example, defining the edge of the film parallel to the sliding direction that is furthest from the centre of the carousel with respect to the second edge of the film as first edge of the film, the system can be configured so that the first edge of the film coincides with a line parallel and close to the tangent to the carousel parallel to the sliding direction. In this way, since the film and the carousel overlap, the compactness of the machine is ensured.
- According to a further embodiment of the present invention a machine is provided in which the transportation device of the film is configured so that, during the transportation of the film along the linear sliding direction, the film does not overlap the carousel. For example, the system can be configured so that the film is arranged so that the second edge of the film, i.e. the edge closest to the centre of the carousel with respect to the first edge of the film, is a lateral distance from the centre of the carousel that is greater than the radius of the carousel.

In other words, the pairs of adjacent seats of different circles are arranged along the same radius of the carousel.
- According to a further embodiment of the present invention a machine is provided in which the seats are arranged on the two concentric circles out of phase, i.e. so that each seat of one of the circles is positioned between two seats of the other circle.

According to a further embodiment of the present invention a machine is provided in which the welding means are arranged in a non-contiguous manner with respect to the direction perpendicular to the sliding direction of the film. In this way a contribution is made to decreasing material waste and to increasing the compactness of the machine.
- According to a further embodiment of the present invention a method is provided for simultaneously packaging a plurality of capsules for producing beverages, for example espresso, by means of a machine comprising a carousel adapted for transporting capsules, housed on the carousel in suitable seats, along a circular direction and a transportation device for transporting a film along a linear sliding direction, wherein the method comprises the following steps: a) transporting the capsules along the circular direction, by means of the carousel during packaging; b) transporting the film along the linear sliding direction on a plane parallel to the carousel, by means of the transportation device; c) cutting closing elements, adapted for closing a surface of the capsules, from the film, so that the imprints of the cutting of the closing elements on the film are arranged along two or more rows that are parallel to each other and offset, so that the space occupied by two or more imprints that are mutually adjacent and belong to two or more distinct rows, respectively, measured along the direction perpendicular to the sliding direction, is less than or equal to the sum of the dimensions of each of the adjacent imprints measured individually along the same direction; and d) applying the closing elements to the capsules so as to close them when the capsules are housed on the carousel.

However, the present invention is not limited to the particular embodiments described in the following detailed description and represented in the figures, but rather the described embodiments simply exemplify the various aspects of the present invention, the purpose of which is defined by the claims. Further modifications and variations of the present invention will be clear to those skilled in the art.

Figures 1 a and 1 b schematically show capsules C for producing beverages that can be packaged by means of the machine and/or the method according to the present invention. The capsules C can, for example, contain soluble and/or infusion products like, for example, ground coffee, milk and/or powdered cocoa, tea leaves or similar. The capsule shown infigure 1 a is open and comprises acapsule body 16 comprising a capsule bottom 17 and a side wall that define the containment volume of the capsule. On the opposite side to the capsule bottom 17, the capsule C is open so as, for example, to be able to insert the product from which the desired beverage is obtained. The side wall of the capsule comprises a projecting edge that defines a surface S on the opposite side to thecapsule bottom 17. The projecting edge surrounds and also defines the opening G of the capsule. The capsule C shown infigure 1a is frusto-conical in shape, so that the surface S is circular, but alternatively the capsule C and therefore the surface S can have any other shape, for example polygonal. -
Figure 1b shows the capsule C offigure 1a closed by means of aclosing element 5. Theclosing element 5 was applied to the projecting edge of the capsule. The closing element can preferably be welded to the projecting edge, for example thermo-welded. Alternatively, theclosing element 5 can be glued to the projecting edge. Theclosing element 5 can be adapted for hermetically closing the capsule, so as to optimise the conservation of the organoleptic properties of the product contained in the capsule. For example, theclosing element 5 can be made of aluminium. Alternatively, theclosing element 5 can for example be a filtering element, for example filter paper or similar. In this case, theclosing element 5 prevents the product contained in the capsule C from coming out from the capsule, but allows for example the passage of gas and/or liquid through its surface. -
Figure 2 schematically illustrates a 3D view of amachine 1 for packaging capsules C for producing beverages according to an embodiment of the present invention. - The
machine 1 comprises acarousel 2 adapted for transporting the capsules C, housed on thecarousel 2 insuitable seats 8, along a circular direction, during the packaging steps. As shown schematically in the figures and as described in detail hereinafter, indeed, the various operative stations of themachine 1 are positioned so as to operate on the capsules C housed in theseats 8 of thecarousel 2. In the case shown in the figures, the circular direction of advancement of the machine is in the anti-clockwise direction and is schematically indicated by the arrow F. - While the
machine 1 is in use, thecarousel 2 rotates around its centre O. The rotation of thecarousel 2 can, for example, be actuated by afirst motor 12. In the embodiment shown infigure 2 thecarousel 2 rotates in the anti-clockwise direction along the direction F. -
Figure 2 shows that theseats 8 of the capsules C are arranged on thecarousel 2 on two concentric circles A and B centred on the centre O of thecarousel 2. According to the present invention, moreover, theseats 8 can be arranged on thecarousel 2 also on more than two concentric circles centred on the centre O of the carousel, for example on 3, 4, 5 or on a greater number of concentric circles. - As shown in
figures 2 ,3 and4 , theseats 8 can be arranged on the two or more concentric circles in phase. In particular, theseats 8 can be arranged on thecarousel 2 so that each n-th capsule CA(n) on the circle A, for example the outermost one, corresponds to the n-th capsule CB(n) on the circle B, for example the innermost one, adjacent to the n-th capsule CA(n). The correspondingseats 8, i.e. for the capsules CA(n) and CB(n), on the two concentric circles, respectively, are, in this way, located substantially along the same radius of thecarousel 2 as shown infigure 3 or infigure 4 . In other words, theseats 8 are arranged side-by-side in pairs along the perimeter of thecarousel 2 so as to form two concentric circles, an outer one A, i.e. with larger diameter, and an inner one B, i.e. with a smaller diameter, and so that the two corresponding seats of the same pair belonging to the two distinct circles are arranged substantially along the same radius of thecarousel 2. This characteristic of the seats arranged in phase on the various circles can also be implemented with a number greater than two of concentric circles. - Alternatively, according to an alternative embodiment of the present invention, the
seats 8 can be arranged on the two or more concentric circles out of phase, as shown schematically infigure 5 . In this way, each of theseats 8, for example for the capsule CA(n) on one of the circles, for example on the outermost circle A, is positioned between twoseats 8, for the capsules CB(n-1) and CB(n) on the inner circle B. In other words, in this configuration, theseats 8 are side-by-side in pairs along the perimeter of thecarousel 2 so as to form two concentric circles, an outer one A, i.e. with a larger diameter, and an inner one B, i.e. with a smaller diameter, and so that the two corresponding seats of the same pair belonging to the two circles are not arranged along a radius of thecarousel 2 but along a chord thereof. This characteristic of the seats arranged out of phase on the various circles can also be implemented with a number of concentric circles greater than two. According to alternative embodiments of the invention, moreover, it is possible to foresee mixed configurations with more than two concentric circles in which on two or more of the circles the seats are arranged in phase whereas with respect to one or more of the other circles the seats are arranged out of phase. - The shape of the
seats 8 shown in the figures is circular, but they can be of any shape, for example polygonal, compatible with the shape of the capsules C to be packaged. - The
machine 1 shown infigure 2 also comprises atransportation device 3 for transporting a film 4, at least partially along a linear sliding direction X that lies on a plane parallel to thecarousel 2. The expression "plane parallel to thecarousel 2" means a plane parallel to the plane defined by the upper surface of thecarousel 2 on which theseats 8 for the capsules are arranged. Thedevice 3 can, for example, comprise a roller pulling system for unwinding the film 4 from an unwindingreel 25 to a windingreel 26. In the embodiment shown infigure 2 , the film 4 moves in the direction indicated by the arrow I. Thetransportation device 3 can comprise one or more pullingrollers 23 and one or more rollers that rotate idly| 24. The pullingrollers 23 are the rollers that actuate the movement of the film 4. The rollers that rotate idly 24 are rollers that rotate freely under the pulling action of the film 4 due to the action of the pullingrollers 23. For example, as shown infigure 2 , the pullingroller 23 can be actuated by asecond motor 13 of themachine 2 so as to unwind the film 4 from the unwindingreel 25 and to wind it back up into the windingreel 26. In alternative embodiments, themotor 12 that sets thecarousel 2 in motion is the same one that sets thetransportation device 3 in motion. - Moreover, as shown schematically in
figure 2 , the rollers that rotate idly 24 can be arranged so as to define the path of the film 4 from the unwindingreel 25 to the windingreel 26. For example, as shown infigure 2 , the system can comprise a first roller that rotates idly 24a and a second roller that rotate idly 24b arranged substantially on the same level so as to define at least one section of the path of the film 4 parallel to the plane of thecarousel 2. Infigure 2 this section is the section between theroller 24a and theroller 24b. - The film 4 is preferably made of flexible material. The film 4 can be made of aluminium, paper, filter paper, multi-layer materials, impermeable materials, filtering materials, or similar.
- As shown in
figures 2 ,3 ,4 and5 the film 4 comprises afirst edge 9 and asecond edge 10 that, in the section of path parallel to thecarousel 2, are parallel to the sliding direction X. The termfirst edge 9 is meant to indicate the edge that, in this section of path, is furthest from the centre O of thecarousel 2 with respect to thesecond edge 10, which, on the other hand, is closer to the centre O thereof. - As shown in
figures 2 ,3 ,4 and5 , the relative position of thecarousel 2 and of the film 4 in the section of path parallel to thecarousel 2 can vary according to alternative embodiments of the present invention. In particular, during the transportation along the sliding direction X parallel to thecarousel 2, the film 4 can at least partially or completely overlap thecarousel 2. Alternatively, the film 4, in this section of its path in which it slides parallel to thecarousel 2, may not overlap the carousel itself but slides laterally with respect to thecarousel 2. -
Figures 2 ,3 and5 show configurations in which the film 4 completely overlaps thecarousel 2 in the section of path in which it slides parallel to thecarousel 2. In particular, in these cases, thetransportation device 3 of themachine 1 is configured so that, during transportation, the film 4 overlaps thecarousel 2 so that thefirst edge 9 of the film 4 coincides with a line parallel and close to the tangent to thecarousel 2 parallel to the sliding direction X. Preferably, thefirst edge 9 of the film 4 coincides with a line intersecting thecarousel 2, parallel to the tangent to thecarousel 2 parallel to the direction X. This configuration promotes the compactness of themachine 1. - According to the embodiment shown, on the other hand, in
figure 4 , thetransportation device 3 is configured so that, during transportation along the sliding direction X parallel to thecarousel 2, the film 4 is arranged so that thesecond edge 10 is a distance from the centre O of thecarousel 2 greater than the radius R of thecarousel 2, so that the film 4 does not overlap thecarousel 2. In this case, the film 4 slides laterally with respect to thecarousel 2. - The
machine 1 according to the present invention also comprises cutting means 11, adapted for cuttingclosing elements 5, for closing the capsules C, from the film 4. The cutting means 11 can for example comprise blade shearing systems, toothed blade shearing systems, die punch or laser cutter. As shown in the figures, the cutting means 11 are configured so as to cut theclosing elements 5 from the film 4 in the section in which the film 4 slides along the sliding direction X parallel to thecarousel 2. When the cutting means 11 cut theclosing elements 5 from the film 4 imprints for cutting the film 4 are made. In particular, upstream of the cutting means 11 in the sliding direction X the film 4 is intact, whereas downstream of the cutting means 11 in the sliding direction X the film 4 has the imprints of the cutting due to the cutting of theclosing elements 5 from the film 4 by the cutting means 11. The cutting means can comprise first cutting means 111 for a first row 71 of imprints of the cutting 6 on the film 4 and second cutting means 11II for a second row 711 of imprints of the cutting 6 on the film 4 (see for examplefigure 7 ). -
Figures 6a and 6b schematically show the imprints of the cutting of the closing elements in a film, respectively according to the state of the art and according to the present invention. - As can be seen clearly in
figure 6b , the cutting means 11 according to the present invention are adapted for cutting theclosing elements 5 so that theimprints 6 of the cutting of theclosing elements 5 on the film 4 are arranged along two or more parallel rows, i.e. along at least one first row 7I and a second row 7II. The two rows 71 and 7II are also parallel to the sliding direction X. Moreover, the two rows 7I and 7II are offset, so that the space occupied by twoimprints 6 that are mutually adjacent and belong to the two distinct rows 71 and 7II, respectively, measured along the direction Y perpendicular to the sliding direction X, is less than or equal to the sum of the dimensions of each of theadjacent imprints 6, measured individually along the same direction Y. For example, as shown schematically infigure 6b , twoimprints 6 of the cutting of theclosing elements 5 that are mutually adjacent and belong to the two distinct rows 71 and 7II, respectively, can be arranged along a direction E forming an angle α comprised between 35° and 55°, preferably between 40° and 50°, preferably 45°, with respect to the sliding direction X of the film 4. - Even if the number of rows of
imprints 6 is equal to two in the attached figures, it is clear that the number of rows based on the present invention can be greater than two. In any case, based on the present invention, the cutting means 11 are adapted for cutting theclosing elements 5 in the section in which the film 4 slides parallel to thecarousel 2 along the sliding direction X so that theimprints 6 of the cutting of theclosing elements 5 on the film 4 are arranged along two or more rows that are parallel to each other and offset, so that the space occupied by the two ormore imprints 6 that are mutually adjacent and belong to the two or more distinct rows, respectively, measured along the direction Y perpendicular to the sliding direction X, is less than or equal to the sum of the dimensions of each of theadjacent imprints 6 measured individually along said same direction Y. In this way the distribution of the imprints of the cutting on the film 4 is optimised so as to minimise the amount of film 4 not used to form theclosing elements 5. - On the other hand, as shown in
figure 6a , theclosing elements 5a, according to the state of the art, are cut along parallel rows that are not offset. In this way, the spatial arrangement of theimprints 6a is such that the unused space between them is very wide and consequently the material of the film that is wasted is high. - A further advantage of the optimised arrangement of the
imprints 6 of the cutting of theclosing elements 5 on the film 4 according to the present invention, is that of allowing a film 4 to be used having a smaller width (i.e. dimension along the direction Y) with respect to the case in which theimprints 6 are arranged along parallel rows that are not offset to cutclosing elements 5 having the same dimensions. This further reduces the amount of material of film 4 required. - The
imprints 6 can be circular in shape, as shown infigure 6b , in the case in which the surface S to be closed of the capsule C is circular. Alternatively, the imprints can be of any other shape, for example polygonal, compatible with the shape of the surface S of the capsule C to be closed. - From what has been stated above, it can be worked out that, in the case in which the
imprints 6 are circular in shape with diameter D, they are arranged on the film 4 so that the lateral distance, i.e. measured along the direction Y, between the centres ofadjacent imprints 6 belonging to different rows 7I and 7II, is less than or equal to the diameter D of asingle imprint 6. - As shown in
figure 7 , the cutting means 11 can be arranged so as to cutclosing elements 5 not adjacent to one another. If for example a first cutting means 11I cuts the n-th closing element 5I(n) of the row 71, a second cutting means 11II can be arranged so as to cut the (n+1)-th closing element 5II(n+1) of the row 7II and not the n-th closing element 5II(n) of the row 7II. Cutting means 11 arranged so as to cutclosing elements 5 that are mutually adjacent, indeed, would have to be distanced apart, due to the bulk thereof, with the consequent increase in distance of theimprints 6 of theclosing elements 5 on the film 4 and thus an increase in material waste. - If, as shown in the embodiments of
figures 2 ,3 and 5e explained above, thetransportation device 3 is configured so that the film 4 overlaps thecarousel 2, the cutting means 11 arranged so as to cutclosing elements 5 that are not adjacent to one another are also arranged so as to cutclosing elements 5 that are applied to capsules C that are not adjacent to one another. If for example the first cutting means 11I cuts the n-th closing element 5I(n) of the row 71, for the n-th capsule CA(n) on the outermost concentric circle A, the second cutting means 1111 cuts the (n+1)-th closing element 5II(n+1) of the row 7II, for the capsule CB(n+1) on the inner concentric circle B and not the n-th closing element 5II(n) of the row 7II, for the capsule CB(n) adjacent to the capsule CA(n). - Once the
closing elements 5 have been cut by the cutting means 11, they can be applied to the surface S of the capsule C by closing means 21, so as to close the capsules C. The closing means 21 are configured to apply theclosing elements 5 to the capsules C when the capsules C are housed on thecarousel 2. The closing means can comprise first closing means 211 for a first row A ofseats 8 of capsules C on thecarousel 2 and second cutting means 1111 for a second row B ofseats 8 of capsules C on the carousel 2 (see for examplefigure 7 ). - Preferably, the closing means 5 are thermo-welded to the capsules by the closing means 21. The closing means 21 can thus comprise welding means, for example thermowelders. In the embodiments shown in
figure 7 , the closing means 21 are at the cutting means 11. In particular, the first closing means 211 are at the first cutting means 11I and the second closing means 2111 are at the second cutting means 11II. As a result, the closing means 5 can be cut from the film 4 and applied to the capsules C in a single operation. - The shape of the cutting means 11 and of the closing means 21 can be any one that is compatible with the shape of the surface S of the capsule C to be closed.
- As shown in
figure 7 , the closing means 21 can be arranged so as to apply theclosing elements 5 to capsules C that are not adjacent to one another in an analogous manner to what is explained above with reference to the cutting means. If for example the first closing means 211 apply aclosing element 5 to the capsule CA(n) on the outermost concentric circle A, the second welding means 21II are positioned to apply aclosing element 5 to the capsule CB(n+1) on the inner concentric circle B and not to the capsule CB(n) adjacent to the capsule CA(n). - In the cases shown in
figures 2 ,3 and5 in which the film 4 overlaps thecarousel 2 in the section of path in which it slides parallel to thecarousel 2, it should be observed that the spatial arrangement of theimprints 6 on the film 4 corresponds to the spatial arrangement of theseats 8 of the capsules C on thecarousel 2. More specifically, theseats 8 of the capsules C are arranged so as to overlap theimprints 6 on the film 4 in the direction Y in the point of tangency between thecarousel 2 and thefirst edge 9 of the film 4. In this way, theclosing elements 5 can be cut and applied to the capsule C in a single operation. It should also be noted that in this case the angular speed with which thecarousel 2 rotates is synchronous with the speed with which the film 4 slides, so that as the film 4 slides, the capsules C in theseats 8 suitably rotate. - On the other hand, in the case shown in
figure 4 in which the film 4 does not overlap the carousel in the section of path in which it slides parallel to thecarousel 2, the spatial arrangement of theimprints 6 on the film 4 may not correspond to the spatial arrangement of theseats 8 of the capsules C on thecarousel 2 even if in the figures this correspondence is shown. According to this embodiment, indeed, theclosing elements 5 are first cut from the film 4 and are then transported to theseats 8 to be applied to the capsules C to close them. In this transportation step it is possible to correct any discrepancy between the spatial arrangement of theimprints 6 on the film 4 and the spatial arrangement of theseats 8 on thecarousel 2. - The
machine 1 according to the present invention can also comprise transportation means for transporting onto thecarousel 2 the open capsules C that must be packaged and for positioning them in theseats 8 of thecarousel 2.Figure 8 shows for example a pair ofconveyor belts 14, adapted for transporting the capsules C, oriented in an orderly manner, close to thecarousel 2. Theconveyor belts 14 can, for example, be positioned, with respect to thecarousel 2, so that the capsules C, at the end of their journey along theconveyor belts 14, fall automatically into theseats 8 of the carousel. In particular, a first conveyor belt is adapted for transporting the capsules C into theseats 8 of a first circle whereas a second conveyor belt is adapted for transporting the capsules C into theseats 8 of the second circle. Moreover, as shown schematically in the figures, themachine 1 can further comprisemobile elements 15, for example mobile arms or thrusting punches for the insertion of the capsules C in theseats 8 on thecarousel 2. The open capsules transported by theconveyor belts 14 can for example come from a tank of open capsules or directly from a machine that produces the open capsules. An example of the positioning of the conveyor belts in the architecture of themachine 1 is shown schematically infigure 2 . - As shown schematically in
figure 9 , themachine 1 can also comprise dosers 20, for filling the capsules C with the desired soluble and/or infusion product when the capsules are housed in theseats 8 of thecarousel 2, in the case in which they arrive on thecarousel 2 empty. In order to reduce the overall bulk of the machine it is preferable, as shown in the figures, in the case in which the machine comprises twodosers 20, i.e. one for each circle ofseats 8 of thecarousel 2, for the two dosers to be arranged out of phase with respect to the direction of rotation of the carousel. In this case, one of the two dosers is further upstream in the direction of rotation of the carousel with respect to the second. The system can comprise different numbers of dosers, for example the system can comprise a single doser with many outlets, one for each of the circles of seats of the carousel. Alternatively, the system can comprise as many dosers as there are circles of seats of the carousel. An example of the positioning of thedosers 20 in the architecture of themachine 1 is shown schematically infigure 2 . The dosers can be arranged between the transportation means of the capsules and the closing means along the direction F of advancement of the machine. -
Figure 10 shows that themachine 1 according to the present invention can further comprise extractor means 22, for discharging the capsules C from thecarousel 2, once they have been closed with theclosing elements 5. Theextractors 22 preferably comprise suction cups, adapted for hooking the capsules C and removing them suitably from theirseats 8. The suction cups can for example grip onto theclosing elements 5 of the capsules. An example of positioning of the extractor means 22 in the architecture of themachine 1 is shown schematically infigure 2 . The extractor means can be arranged between the closing means and the transportation means of the capsules along the direction F of advancement of the machine. - The
machine 1 shown infigure 2 thus comprises acarousel 2 comprisingseats 8 for the capsules C so as to transport the capsules along a circular direction during packaging, transportation means 14 for transporting open capsules towards thecarousel 2 and for inserting them in theseats 8 of thecarousel 2, atransportation device 3 for transporting a film 4 along a linear sliding direction X that lies on a plane parallel to the carousel, cutting means 11 for cuttingclosing elements 5 from the film in the section in which it slides along the linear sliding direction X and closing means 21 configured to apply theclosing elements 5 to the capsules C when the capsules are housed on thecarousel 2, wherein the cutting means 11 are adapted for cutting theclosing elements 5 so that theimprints 6 of the cutting of theclosing elements 5 on the film 4 are arranged along two ormore rows 7 that are parallel to each other and offset, so that the space occupied by two ormore imprints 6 that are mutually adjacent and belong to the two or moredistinct rows 7, respectively, measured along the direction Y perpendicular to the sliding direction X, is less than or equal to the sum of the dimensions of each of theadjacent imprints 6 measured individually along the same direction Y. - The
machine 1 can optionally comprisedosers 20 to fill the capsules housed in theseats 8 of thecarousel 2. As shown infigure 2 thedosers 20 can advantageously be arranged between the transportation means 14 and the closing means 21 along the circular direction of advancement F of the machine defined by thecarousel 2. - The
machine 1 can also further comprise extraction means 22 to extract the packaged capsules from thecarousel 2. As shown infigure 2 the extraction means 22 can be advantageously arranged between the closing means 21 and the transportation means 14 along the circular direction of advancement F of the machine defined by thecarousel 2. - According to the present invention a method is also provided for packaging capsules C for producing beverages, for example espresso, by means of a
machine 1 comprising acarousel 2 adapted for transporting capsules C, housed on thecarousel 2 insuitable seats 8, along a circular direction and atransportation device 3 for transporting a film 4 along a linear sliding direction X. - The method foresees the transportation of the capsules C along the circular direction, by means of the
carousel 2 during packaging; the transportation of the film 4 along the linear sliding direction X on a plane parallel to thecarousel 2, by means of thetransportation device 3; the cutting of closingelements 5, adapted for closing a surface S of the capsules C from the film 4 so that theimprints 6 of the cutting of theclosing elements 5 on the film 4 are arranged along two ormore rows 7 that are parallel to each other and offset, so that the space occupied by two ormore imprints 6 that are mutually adjacent and belong to two or more saiddistinct rows 7, respectively, measured along the direction Y perpendicular to the sliding direction X, is less than the sum of the dimensions of each of theadjacent imprints 6 measured individually along the same direction Y; the application of theclosing elements 5 to the capsules C so as to close them when the capsules C are housed on thecarousel 2. - The transportation of the capsules along the circular direction by means of the carousel during packaging indicates that the capsules are transported by the carousel along the circular direction of advancement so as to carry out the various steps of the packaging of the capsules while the capsules are housed on the carousel. In other words, the carousel, with its rotation in the circular direction of advancement of the machine, allows the capsules to be brought to the various operative stations of the machine so as to carry out the steps of the method for packaging the capsules while the capsules are housed on the carousel.
- The
carousel 2 comprising theseats 8, thetransportation device 3, the film 4, the cutting means 11 and the welding means 21 can have the characteristics already described earlier, with reference to themachine 1 for simultaneously packaging a plurality of capsules C for producing beverages. - Preferably, the capsules C are loaded onto the
carousel 2. More specifically, the capsules C are brought into theseats 8 on thecarousel 2. For example, this can occur by means of one ormore conveyor belts 14, which carry the capsules C, oriented in an orderly manner and open, close to thecarousel 2. Theconveyor belts 14 can, for example, be positioned, with respect to thecarousel 2, so that the capsules C, at the end of their journey, fall automatically in theirseats 8. An example of this step is shown schematically infigure 8 . -
Mobile arms 15 can, for example, take care of the subsequent insertion of the capsules C in theseats 8 of thecarousel 2. - Before the capsules C are closed, they can be filled with the soluble and/or infusion product P for producing the desired beverage, by means of, for example, the use of
suitable dosers 20. In the embodiment shown infigure 9 , thedosers 20 are shaped like inverted cones, but any other shape is suitable for being used. Thedosers 20 ensure that the correct amount of product that must be contained in the capsule C itself is deposited inside the capsule C. This step of the method, an example of which is shown schematically infigure 9 , only takes place in the case in which the capsules C arrive on thecarousel 2 empty. In this case, if the surface S of the capsule C is the only open surface of the capsule C, it is, indeed, necessary to fill them before the surface S is closed by theclosing elements 5. - Therefore, the
closing elements 5, previously cut by the cutting means 11 from the film 4, are preferably applied to the capsules C, so as to close, for example hermetically, the surface S. The application of theclosing elements 5 can take place, for example, by thermowelding, by means of the welding means 21. An example of this step is schematically illustrated infigure 7 in the case in which the film 4 and thecarousel 2 overlap. In this case, indeed, infigure 7 it is also possible to see the step of cutting theclosing elements 5 from the film 4. - Finally, the capsules C are preferably discharged from the
carousel 2, by means of theextractors 22. Theextractors 22 can comprise suction cups adapted for gripping the capsules C and removing them suitably from theirseats 8. In this way, theseats 8 are freed from the closed capsules C, so that new open capsules C can be loaded onto thecarousel 2. An example of this step is schematically illustrated infigure 10 . - Even if the present invention has been described with reference to the embodiments described above, it is clear to those skilled in the art that it is possible to make different modifications, variations and improvements of the present invention in light of the teaching described above and in the attached claims, without departing from the object and the scope of protection of the invention.
- For example, the shape of the surface S of the capsules C and therefore the shape of the
imprints 6 that the cutting means 11 produce on the film 4 can be whatever is suitable. Moreover, cases have been shown in which the imprints of the cuts are arranged on two rows that are parallel and offset, but the number of rows can be greater than two. It is clear that in analogy also the number of concentric centres A, B on which theseats 8 for the capsules C on thecarousel 2 are arranged can be greater than two. - Finally, that which is deemed to be known by those skilled in the art has not been described in order to avoid needlessly excessively overshadowing the described invention.
- Consequently, the invention is not limited to the embodiments described above, but it is only limited by the scope of protection of the attached claims.
