DETAILED DESCRIPTION

[0060] Hereinafter, the present invention is described with reference to particular embodiments as illustrated in the attached tables of drawings. 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.

Main Embodiment

[0061] FIG. 1a shows an object 100 having two ends: one upper 101 and one lower 102. The upper end 101 has a projecting edge 103 that projects from such an end. For example, such an object 100 can be a capsule used commonly for preparing beverages like coffee or similar. However, it is clear that such objects can also be for example small containers or more generally bodies having an upper projection 103.

[0062] Such objects 100 also have a side outer surface 104 that is configured so as to connect the upper end 101 with the lower end 102 and can have any shape like for example cylindrical, frusto-conical or even a combination thereof.

[0063] The projecting edge 103 of the object 100 makes it difficult to effectively pack a plurality of objects 100 inside a package. Indeed, the presence of the projecting edge 103, being bulky, makes it difficult to effectively use the space inside the package within which such objects 100 are placed.

[0064] As shown in FIG. 1b, in order to makes it possible to effectively use the space of the box 200 inside which such objects 100 are contained, generally they are arranged with alternate orientation so as to effectively fill the space of the package inside which they are contained.

[0065] Therefore, as shown in the example in the figures, in the case in which the objects have been introduced inside the package 200 along the conveying direction Ax1 they are arranged one on top of the other. Such objects 100 are oriented alternately with the upper end 101 facing to the left and with the upper end 101 facing to the right. In this way, it is thus possible to effectively reduce the space occupied by said objects 100 with respect to the case in which they are always inserted along the direction Ax1 but all having the same orientation towards the right/left.

[0066] As shown in FIG. 2a, such an orientation process of the objects 100 is carried out through a machine 1000. Such a machine 1000 comprises a rotatable device 4. Such a rotatable device 4 is configured so as to be able to receive the objects 100 and, after having rotated them, is configured so as to be able to make them come out with a desired orientation.

[0067] In the example of FIG. 2a the rotatable device 4 can be connected to an entry guide 3 configured so as to supply the objects 100 and to an exit guide 5 configured so as to receive the objects 100 exiting from the rotatable device 4.

[0068] As stated earlier, both the entry guide 3 and the exit guide 5 are represented by any element having walls that are preferably slightly further apart with respect to the width of the projecting edge 103 of the object 100. For example, such exit guides 5 can be represented by a case, or by a package that contains the objects 100 to be for example put on sale, or even by conveying tracks like those represented in the figures.

[0069] As can clearly be seen from the view of FIG. 2b, the objects 100 can be conveyed along the entry guide 3 towards the rotatable device 4. Such objects 100 preferably all have the same orientation that, in the particular case depicted, corresponds to having the upper end 101 facing downwards. However, it is clear that the orientation could very well also be the opposite, i.e. the upper end facing upwards.

[0070] Such objects 100 are then conveyed in the exit guide 5 with alternate orientation as described above. As shown in the figures, the exit guide 5 can be represented by a guide having two parallel walls adapted for conveying the objects 100, previously oriented, along an exit direction.

[0071] As shown in the figure, the rotatable device 4 is preferably formed from a rotatable shaft 41 configured so as to ensure the rotation of a rotatable terminal 42. The rotatable shaft 41 is preferably connected to a control member capable of regulating the rotation of the shaft 41 and thus of the terminal 42 connected thereto.

[0072] As shown in FIG. 2a, the rotatable device 4 is preferably configured so as to rotate around an axis perpendicular with respect to the plane formed by the direction of the entry guide 3 and by the direction of the exit guide 5.

[0073] As shown in the figure, according to this particular embodiment, the rotatable device has a rotatable terminal 42 having two guides: a first guide 7 and a second guide 9. Both of the guides 7 and 9, as shown in the figures, have two grooves. Each of the grooves is arranged on an opposite side of the guide, and they are configured so as to receive the projecting edge 103 of the objects 100 to be rotated. In this way, the objects 100 can be conveyed along the first guide 7 and the second guide 9 having the projecting edge channeled in such grooves and, during the rotation of the rotatable terminal 42, it will be possible in this way to prevent the objects 100 from coming out along a direction perpendicular to the direction of each guide.

[0074] The first guide 7, in this particular embodiment, is a through guide. Therefore, it is thus possible, for the object 100 that is located in such a guide, to come out from either of the two openings of the first guide 7.

[0075] The second guide 9, in this particular embodiment, is a blind guide that thus has a single entry/exit. Therefore, the object 100 that will be introduced inside it can only come out from the position in which it entered inside the second guide 9.

[0076] Moreover, the first guide 7 and the second guide 9 preferably have at least one retaining system of the objects 8 capable of stopping any possibility of the objects 100 coming out during the rotation of the rotatable device 4. Such a retaining system of the objects 8 is represented, in this particular case shown in the figures, by a projection configured so as to be able to be extended and/or retracted along a direction perpendicular with respect to the conveying direction of the objects 100 inside the two guides 7 and 9.

[0077] Therefore, in the case in which it is wished to prevent any possibility of the objects 100 coming out along a direction parallel to the direction of the guides 7 and 9, during the rotation of the rotatable device 4, such a projection will project inside the guides 7 and 9 so as to stop the object 100 that, due to the force of gravity and the centrifugal forces that act on it during the rotation of the rotatable device, could otherwise have come out from the guides 7 and 9.

[0078] Hereinafter, with reference to FIGS. 4 to 9, the operative steps of the machine 1000 shown in FIG. 2 are described and a method for orienting the objects 100 according to the main embodiment of the present invention is then described.

[0079] As shown in FIG. 4, the entry guide 3 has a motion control system 6 configured so as to regulate the flow of objects 100 inside the rotatable device 4. Such a system 6 is represented, in this particular case shown in the figures, by a projection configured so as to be able to be extended and/or retracted along a direction perpendicular with respect to the conveying direction of the objects 100.

[0080] Therefore, in the case in which it is wished to temporarily stop the flow of objects 100, such a projection will project inside the guide so as to stop the object 100 before it has entered inside the rotatable device 4. In the case in which, after a certain amount of time, it is wished to allow the object 100 to enter inside the rotatable device 4, the projection will be retracted and access will thus be permitted.

[0081] As will be explained hereinafter, with such a motion control system 6 it is also possible to regulate the number of objects made to pass inside the rotatable device 4. Therefore, for example, in the case in which it is wished to pass a greater number of objects 100 it will be possible to leave the system 6 in retracted position for a longer time period.

[0082] Based on alternative embodiments of the present invention, the motion control system 6 can be a coupling that sets the rate of the objects to be made to pass and/or a device that transfers a predetermined precise motion to the objects to be made to pass.

[0083] As shown in the figure, a first object 100 is made to enter inside the first guide 7. Such an object can be moved for example through compressed air, vibration or a lateral transportation chain capable of driving such an object 100 inside the guide along a desired direction. The object 100 entered in the first guide 7, which is the through guide, will stop against the retaining system of the objects 8 that will be in a stopped condition and thus projecting inside the first guide 7 (differently from what is depicted in the figures).

[0084] After this, as shown in FIG. 5, the rotatable device 4, in the particular embodiment represented in the figures, will preferably rotate by 90 in the clockwise direction R1. In this way, after the rotation by 90 the second guide 9 will be aligned with the entry guide 3 and the first guide 7 of the rotatable device 4 will be aligned with the exit guide 5.

[0085] As shown in FIG. 6, after having been rotated by 90, the rotatable device 4 is ready to receive the new object 100 inside the second guide 9. Therefore, the motion control system 6 arranged on the entry guide 3, retracting, will allow the entry of such an object 100 inside the second guide 9.

[0086] In the same way, the object 100 that is located inside the first guide 7 of the rotatable device 4 is ready to be conveyed inside the exit guide 5. Therefore, the two processes described above, i.e. that of entry of a new object 100 inside the second guide 9 and that of exit of the object 100 contained inside the first guide 7, can preferably be carried out simultaneously so as to reduce the time necessary to carry out both processes.

[0087] Therefore, the retraction of the retaining system of the objects 8 positioned on the first guide 7 can take place at the same time as the retraction of the motion control system of the objects 6 positioned on the entry guide 3. However, it is clear that for various requirements it will also be possible to temporally separate two processes making them occur in sequence one after the other with the order dictated by the particular constructive requirement.

[0088] It is clear that the rotation by 90 refers to the particular embodiment described in the figures, where the direction of the entry guide 3 is perpendicular with respect to the direction of the exit guide 5. However, in the case for example in which the angle formed between the direction of the entry guide 3 and of the exit guide 7 is equal to 60, the rotation of the rotatable device 4 will in this particular case be equal to 60.

[0089] As shown in the section view of FIG. 7 of the machine 1000, the first guide 7 is perfectly aligned with the exit guide 5 whereas the second guide 9 is perfectly aligned with the entry guide 3 so that the movement of the objects 100 can be carried out without problems and/or hindrances.

[0090] The exit of the object 100 present inside the first guide 7 can take place, as stated earlier, thanks to the opening of the retaining device of the objects 8.

[0091] In the particular embodiment described in the figures, given that the direction of action of the force of gravity and the direction of the exit guide 5 are parallel, the exit of the object 100 from the rotatable device 4 is ensured by the force of gravity. However, in the case in which such a force is not sufficient, an additional system can be installed, such as a movement device or a blower that makes it possible to extract the object 100 and convey it inside the exit guide 5.

[0092] As stated earlier, the second guide 9 can also have a retaining system of the objects 8 analogous to the one present inside the first guide 7. Therefore, also in this case by extending and retracting such a retaining system of the objects 8, it is thus possible to prevent the possibility of such an object 100 coming out during the rotation of the rotatable device 4.

[0093] Also in this case, in order to allow the object 100 to enter inside the second guide 9, it is possible to use the motion control system of the objects 6 described above.

[0094] After an object 100 is inserted inside the second guide 9 and the object 100 that was present inside the first guide 7 is conveyed inside the exit guide 5, as shown in FIG. 8, the rotatable device 4 can be rotated by 90 in a counter-clockwise direction R2 to allow the first guide 7 to receive a new object 100 and the second guide 9 to convey the object 100, arranged in it, inside the exit guide 5.

[0095] As shown in FIG. 9, at this point the first guide 7 of the rotatable device 4 is perfectly aligned with the entry guide 3 whereas the second guide 9 is perfectly aligned with the exit guide 5. At this point, in the same ways described earlier, the release and conveying of the object 100 contained inside the second guide 9 of the rotatable device 4 inside the exit guide 5 and the entry of a new object 100 inside the first guide 7 of the rotatable device 4 take place.

[0096] As can be clearly seen, looking respectively at FIGS. 7 and 9, the objects are conveyed inside the exit guide 5 with alternate orientation. In the particular example described by the figures, the first guide conveys the objects 100 with the upper end 101 facing to the left, vice-versa the second guide 9 conveys the objects 100 with the upper end 101 facing to the right.

[0097] As can be seen from the above description, whereas the first guide 7 is configured so as to allow the objects 100 conveyed in it to come out from the opposite side with respect to that in which they entered, thus making it possible to continue in the exit guide 5 along with the same orientation with which they entered in the first guide 7, the second guide 9 is configured so as to make objects 100 introduced in it come out from the same side at which they entered and then convey them with a tilted orientation. This exact characteristic is what makes it possible to alternate the orientations of the objects 100 inside the exit guide 5.

[0098] It is clear that if the orientation of the objects 100 inside the entry guide 3 was the opposite to that depicted, the orientation of the objects 100 inside the exit guide 3 would be exactly the opposite. However, it will still be alternate.

[0099] This process described above can be repeated infinite times and thus makes it possible, through a rotation of the alternate type, to effectively convey the objects 100 inside the exit guide 5 having an alternate orientation.

[0100] However, it is also possible for the rotatable device 4 to rotate continuously. This way (not shown in the figures) will not change anything of the conveying processes described above, and indeed all that will change will be the direction of rotation of the rotatable body 4 as will be clear hereinafter.

[0101] Hereinafter a brief description of how such a process can be carried out will be given.

[0102] After a first object 100 has been conveyed inside the first guide 7, the rotatable device 4 will rotate in the clockwise/counter-clockwise direction until such a first guide 7 is perfectly aligned with the exit guide 5.

[0103] At this point, the object 100 contained inside the first guide 7 will be conveyed inside the exit guide and a new object 100 will be conveyed inside the second guide 9 in the same ways described above. After this, by rotating in the same clockwise/counter-clockwise direction described above, the rotatable device 4 will be rotated until the second guide 9 is aligned with the exit guide 5 and consequently until the entry guide 3 is aligned with the first guide 7.

[0104] This process described above is thus analogous to the alternate one described above. The advantage obtained through such a system is that the rotatable device can always rotate in the same direction. In addition, such a rotatable device 4 can also be made to rotate continuously. On the other hand, the drawback thereof is that in this way the rotatable device 4 will complete revolutions of 360 and therefore there will be greater rotations with respect to the case of alternate motion. This could also take longer revolution times.

[0105] In FIG. 10 a further embodiment of the present invention is presented. As described earlier, the motion control system of the objects 6 can be configured so as to be able to ensure the passage of a predetermined number of objects 100.

[0106] Therefore, according to this embodiment, a machine 1000 is arranged having a second exit guide 11 positioned along the same direction as the entry guide 3 on an opposite side with respect to the rotatable device 4. Therefore, an object 100 can, starting from the entry guide 3, enter into the first guide 7 of the rotatable device 4 and exit from the rotatable device 4 and enter into the second exit guide 11.

[0107] Therefore, it is thus possible to convey a predetermined number of objects 100 inside the second exit guide 11. After such objects have been driven inside the second exit guide 11, it is possible to begin conveying the objects inside the first guide 7 and the second guide 9 of the rotatable device 4 as described earlier.

[0108] The presence of the second exit guide 11 makes it possible, in the case in which it is not only wished to alternate the objects 100 on the exit guide 5 described above, to transfer the objects 100 also along the second exit guide 11 without manipulating them and to send them for example to another packaging system such as a packet (not depicted) configured so as to receive a plurality of objects.

Second Embodiment

[0109] As shown in FIG. 11, the exit guide 5 can preferably be adjacent to one or more exit guides 5a, 5b forming a plurality of exit guides. In the example depicted in FIG. 10, two exit guides 5a, 5b are adjacent to one another.

[0110] This particular embodiment makes it possible to fill for example cases or packages one after the other in a quick and efficient manner. After a predetermined number of objects 100 have been conveyed inside the exit guide 5a, the exit guide 5a containing the objects 100 can be translated together with the exit guide 5b arranged adjacent along the translation axis Ax2.

[0111] Such a translation along the translation axis Ax2 can be ensured by movement means 43, like for example a translation chain.

[0112] After the exit guide 5a that, in the particular example presented in FIG. 10, is arranged to the left, has been translated to the left in the direction indicated by the translation axis Ax2, the objects can be conveyed in a second exit guide 5b arranged to the right with respect to the exit guide 5a.

Third Embodiment

[0113] According to another embodiment of the present invention, as shown in FIG. 12, the machine 1001 can have a plurality of entry guides, a plurality of exit guides and a rotatable device 4 having a plurality of first guides and a plurality of second guides inside it.

[0114] In the particular example represented in FIG. 12, the plurality of entry guides is made up of two entry guides 3a, 3b whereas the plurality of exit guides is made up of two exit guides 5a, 5b. Moreover, the rotatable device 4 has two first guides 7a, 7b and two second guides 9a, 9b. However, it is clear to those skilled in the art that such a number of parallel guides can be increased as desired. The two first guides 7a, 7b and the two second guides 9a, 9b will have analogous characteristics to those described for the first embodiment.

[0115] Moreover, the parallel guides of the rotatable device can be connected to independent motorizations for example through concentric actuation shafts.

[0116] The machine 1001 having such a configuration makes it possible to convey the objects 100 inside the plurality of exit guides in parallel. The orientation process is exactly the same as described above since for example the first entry guide 3a, the first guide 7a of the rotatable device 4, the second guide 9a of the rotatable device 4, and the first exit guide 9a correspond for example to the orientation line of the machine 1000 described in the main embodiment of the present invention.

[0117] In parallel to this orientation line, there will be a plurality of other orientation lines characterized in that they can work parallel with respect to the other orientation lines since the rotation of the rotatable device 4 regulates the orientation of each orientation line.

[0118] For example, in the case in which it is wished to have x parallel lines it will be sufficient to add x orientation lines in parallel.

[0119] Moreover, as shown in the particular example of FIG. 12, also in this case the machine 1001 can have exit guides 5a, 5b configured so as to be able to be translated along the translation axis Ax3.

[0120] Such a translation along the axis Ax3 can, also in this case, be ensured by movement means, like for example a translation chain.

[0121] For example, after the plurality of guides 5a, 5b have been filled, in the particular example presented in FIG. 10, such guides are moved forwards and two new guides are positioned in their place so as to be able to receive said objects 100 coming from the rotatable device 4.

Fourth Embodiment

[0122] In FIG. 14 a further embodiment of the present invention is presented. The figure shows a machine 1002 which has a rotatable device 41 having a single through guide 7. Also in this case, as shown in the figures, such a through guide 7 will have two grooves arranged on opposite faces of the guide so as to allow the projecting edges 103 of the objects 100 to be tilted to be at least partially inserted in such grooves

[0123] In this case, the exit guide 5 can preferably be arranged along the same direction as the entry guide 3. In this way, the objects 100 present in the entry guide 3 are driven inside the exit guide 5 with an orientation with respect to the exit guide 5 that is equal or opposite to that which they had with respect to the entry guide 3.

[0124] The rotatable device 41 is configured so as to allow the objects 100 to be conveyed inside the exit guide both after having carried out a rotation by 180 inside the rotatable device 41 and in the absence of any rotation of the rotatable device 41. The rotatable device 41 can be configured both to rotate in an alternate and continuous manner.

Fifth Embodiment

[0125] According to another embodiment of the present invention, as shown in FIG. 15 the machine 1003 can have a rotatable device 411 that is configured so as to rotate around an axis coinciding with the direction of the entry guide 3 and with the direction of the exit guide 5.

[0126] As shown in the figure, the rotatable device 411 is connected to a rotation shaft 451 through for example a belt or any other transmission member capable of effectively allowing a transmission of the rotary motion of the rotation shaft 451 to the rotatable device 411.

[0127] In turn, the rotation shaft 451 is connected to a motor 45, like for example an electric motor, which can in turn be connected to a control device that regulates the motor 45.

[0128] As shown in the particular view of FIG. 16, the entry guide 3 and the exit guide 5 are preferably arranged along the same direction. However, as stated above, both the entry guide 3 and the exit guide 5 could also be curvilinear.

[0129] The rotatable device 411, shown in FIG. 17, has an inner passage 411a inside it configured so as to ensure the passage of the objects through it. On the surface of the inner passage 411a there are two guides 30 and 31. Preferably, the two guides 30 and 31 are each formed from two grooves arranged on the inner surface of the rotatable device 411. Such guides are configured so as to be able to receive the projecting edge 103 of the objects 100.

[0130] Such guides are preferably offset by 180. Moreover, each of the guides 30 and 31 preferably has a retaining system of the objects 8 capable of allowing the object 100 arranged inside such guides 30 and 31 to be stopped.

[0131] Hereinafter, the method for using the machine 1003 will be briefly presented.

[0132] The objects 100, in this particular embodiment, can be made to slide inside the entry guide 3, thanks for example to the effect of the force of gravity. However, it is always possible, in order to ensure an effective movement of the objects 100, to use movement systems described for the other embodiments.

[0133] Also in this case, the entry guide 3 can have a motion control system 6 for the entry in phase inside the rotatable device 411 analogous to the one described in the other embodiments.

[0134] When the motion control system 6 allows a first object 100 to come out inside the rotatable device 411, the latter will receive such an object 100 inside a first of the two guides 30 and 31. Meanwhile, the retaining system of the objects 8 prevents the object 100 from coming out from the rotatable device 411.

[0135] At this point, the rotatable device 411 can rotate preferably by 180, retract the retaining system of the objects 8 and then convey the object 100 inside the exit guide 5. A second object 100 positioned inside the entry guide 3 will be driven inside the rotatable device and, passing through a second of the two guides 30 and 31, will be introduced directly inside the exit guide 5.

[0136] After this, a third object 100 contained inside the entry guide 3 will be driven inside the rotatable device 411 and will be held in it through the retaining system of the objects 8. After having rotated by 180, the process described above for releasing such a third object 100, for making a fourth object 100 enter, for conveying the fourth object 100 inside the exit guide 5, and for making a fifth object 100 enter inside the rotatable device 411 will be repeated.

[0137] It will be clear to those skilled in the art that such a method can undergo numerous changes and variations. For example, after having inserted the second object 100 inside the exit guide 5, the rotatable device 411 can be made to rotate into its initial idle position and the process can be repeated in sequence.

[0138] Moreover, it is also clear that the rotatable device 411 can have a greater number of guides. It is also clear that the guides 30 and 31, instead of being formed from grooves inside the inner surface of the rotatable device 411, can be formed from any other shape capable of allowing the rotation of the object 100 inserted in them.

[0139] Although the present invention has been described with reference to the embodiments described above, it will be 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 covered by the attached claims without departing from the object and from the scope of protection of the invention. Moreover, the different embodiments described above can be combined with each other.

[0140] For example, although in the figures an entry guide 3 has been described having a lower height than the height of the objects 100, such an entry guide 3 can have a height greater than or equal to the objects 100. Moreover, it can have grooves adapted for receiving the projecting edge 103. With such a configuration it is thus possible to have an entry guide 3 with two inner walls having a distance smaller than the width of the projecting edge 103

[0141] Moreover, although entry guides have always been represented positioned horizontally, it is clear that such guides can also be inclined with any angle of inclination. Moreover, such guides can also not be rectilinear in the case in which there are conditions that make a non-rectilinear guide more advantageous.

[0142] Moreover, the rotatable device that has been described with one or two guides can also have four guides that make it possible to speed up the orientation process, so as to contain four objects simultaneously.

[0143] Moreover, the rotatable device having many parallel guides can be both configured so as to allow the rotation in phase of said guides through for example the use of a single motor, and to allow the out-of-phase rotation through for example the use of many motors. Moreover, by using many motors, it is also possible to rotate the different parallel guides with different rotation speeds.

[0144] Finally, anything that is considered known to those skilled in the art has not been described in order not to needlessly excessively complicate the invention described.

[0145] Consequently, the invention is not limited to the embodiments described above, but is only limited by the scope of protection of the attached claims.
