Description

Technical Field

[0001] The present invention relates to a conveying device for a packaging machine, and more particularly to a conveying device for advancing a package filled with a pourable product, particularly a pourable food product.

[0002] Advantageously, the present invention also relates to a packaging machine having at least one conveying device for packaging a pourable product, particularly a pourable food product, in a package, particularly a package formed from a multi-layer packaging material.

[0003] Furthermore, the present invention also relates to a carrier for a conveying device for advancing a package filled with a pourable product, particularly a pourable food product.

Background Art

[0004] As is well known, many liquid or pourable food products, such as fruit juice, UHT (ultra-high temperature treated) milk, wine, tomato sauce, etc., are sold in packages made from sterilized packaging materials, particularly sealed packages.

[0005] As a typical example, there is a parallelepiped-shaped package for a pourable food product known as Tetra Brik Aseptic (registered trademark), which is made by sealing and folding a laminated strip-shaped packaging material. This packaging material has a multi-layer structure including a base layer of carton and / or paper, and both sides are covered with layers of heat-sealing plastic material, such as polyethylene. In the case of aseptic packaging for long-term preservable products, the packaging material includes a layer of oxygen barrier material, such as aluminum foil, which layer overlaps with a layer of heat-sealing plastic material and is further covered with another layer of heat-sealing plastic material to finally form the inner surface of the package that contacts the food.

[0006] This type of package is usually produced by a fully automatic packaging machine, which forms and fills the package from multi-layer packaging materials. Such an automatic packaging machine has a very high production speed (more than 10,000 pieces per hour or higher).

[0007] In recent years, in this industry, it has been desired to handle the packages in a more flexible manner after the formation of the packages, especially to transport the packages in a more flexible and particularly expandable way.

[0034] Referring particularly to FIG. 1, the packaging machine 1 may include - a package filling device 10 for filling the packages 2, in particular for forming and filling the packages 2, and more particularly for forming the packages 2 from a multi-layer packaging material and filling the packages 2; - at least one conveying device 11 for conveying the packages 2 from the inlet station 12 to the outlet station 13. and may be provided with.

[0035] In particular, the conveying device 11 may be arranged downstream of the package filling device 10. That is, the conveying device 11 receives the packages 2 from the package filling device 10 during use.

[0036] According to some possible non-limiting embodiments, the packaging machine 1 may include one or more conveying devices 11. Two or more conveying devices 11 may be arranged parallel to each other. That is, each conveying device 11 may receive respective portions of the packages 2 during use.

[0037] Alternatively or additionally, two or more conveying devices 11 may be arranged in series with each other. That is, two or more conveying devices 11 convey a plurality of identical packages 2.

[0038] Referring particularly to FIGS. 2 to 7, each conveying device 11 includes - a plurality of carriers 14, each configured to carry (at a time) at least one, particularly only one, package 2, - a planar motor 15 configured to selectively and independently move each carrier 14, - at least one inlet conveyor 16 configured to advance the package 2 from the inlet station 12 to the receiving station 17, where each package 2 is transferred to its respective carrier at the receiving station, - at least one outlet conveyor 18 configured to advance the package 2 from a discharge station 19 where each package 2 is discharged from each carrier 14, particularly transferred from each carrier 14 to the outlet conveyor 18, to the outlet station 13. It may include.

[0039] Preferably, each conveying device 11 may include its own respective control unit 20 configured to control the operation of the conveying device 11 itself. In particular, the control unit 20 may be configured to control the operation of the planar motor 15 for controlling the advancement of the carrier 14.

[0040] According to some possible non-limiting embodiments not shown, the conveying device 11 may include a plurality of inlet conveyors 16 and / or a plurality of outlet conveyors 18. Preferably, each inlet conveyor 16 may be associated with one respective inlet station 12, particularly one respective receiving station 17, and / or each outlet conveyor 18 may be associated with one respective outlet station 13, particularly one respective discharge station 19.

[0041] In particular, referring to FIGS. 4 to 6c, each carrier 14 includes respective support bases 24, and a holding device 25 that is controllable between an open configuration (see FIGS. 5a, 6a, and 6b) in which respective holding devices 25 enable receipt or release of respective packages 2, and a holding configuration (see FIGS. 5b and 6c) in which respective holding devices 25 hold respective packages 2.

[0042] In particular, each support base 24 may be configured to carry respective packages 2 and / or may be configured to carry respective holding devices 25.

[0043] Preferably, each holding device 25 may be fixed to respective support bases 24 and / or may extend from respective support bases 24.

[0044] More specifically, in use, packages 2 may be arranged on respective carriers 14, particularly on respective support bases 24, such that respective longitudinal axes are transverse, particularly perpendicular, to carriers 14, particularly support bases 24. In particular, each first wall 4 may contact the support base 24 when arranged on respective carriers 14.

[0045] In particular, in use, by controlling respective holding devices 25 into respective holding configurations, forward movement of packages 2 due to forward movement of carriers 14 can be performed in a safe manner.

[0046] Furthermore, each conveying device 11 may include a control device 26 for controlling each holding device 25 between respective open configurations and respective holding configurations, particularly selectively controlling.

[0047] More specifically, control device 26 is configured to control each holding device 25 from respective open configurations to respective holding configurations after and / or during receipt of respective packages 2 at receiving station 17, and to control each holding device 25 from respective holding configurations to respective open configurations before and / or during release of respective packages 2 at release station 19, particularly selectively controlling.

[0048] More specifically, each inlet conveyor 16 and each outlet conveyor 18 may be configured to advance each package 2 so that each package 2 is spaced apart from the planar motor 15 during use, and an intervening space 27 is formed between the planar motor 15 and the package 2, enabling each support base 24 of each package 2 to be interposed between the planar motor 15 and each package 2.

[0049] In this way, it is possible to arrange the support base 24 between the planar motor 15 and the package 2 and place the package 2 on the support base 24.

[0050] Furthermore, the planar motor 15 may be configured to synchronize the advancement of each carrier 14 with respect to each package 2 when each package 2 is advanced by each inlet conveyor 16 or each outlet conveyor 18 during use.

[0051] According to some preferred non-limiting embodiments, the planar motor 15 may be configured to advance the carrier 14 from the inlet conveyor 16 to the outlet conveyor 18, particularly when each package 2 is loaded. In particular, the planar motor 15 may be configured to individually and selectively control the advancement of each carrier 14 between the inlet conveyor 16 and the outlet conveyor 18.

[0052] Preferably, the planar motor 15 may be configured to advance the carrier 14 from the outlet conveyor 18 to the inlet conveyor 16, particularly after each package 2 has been released (i.e., when newly emptied).

[0053] For example, the conveying device 11 may include one or more processing and / or measuring and / or analyzing units 28 configured to process and / or measure and / or analyze the package 2. Each processing and / or measuring and / or analyzing unit 28 may be arranged at each station 29.

[0054] The processing and / or measuring and / or analyzing unit 28 may be configured to, for example, inspect the quality of the package 2, and / or scan the package 2, and / or decorate the package 2.

[0055] In particular, the planar motor 15 may be configured to selectively control the forward movement of the carrier 14, for example, to directly transfer the package 2 from the inlet conveyor 16 to the outlet conveyor 18, or to transfer the package 2 from the inlet conveyor 16 to one or more processing and / or measuring and / or analyzing units 28 and then to the outlet conveyor 18 (i.e., to indirectly transfer the package 2 from the inlet conveyor 16 to the outlet conveyor 18).

[0056] More specifically, each inlet conveyor 16 may be configured to advance the package 2 along an inlet path P, in particular a straight inlet path P.

[0057] More specifically, the inlet path P may extend between the inlet station 12 and the terminal station 30. In particular, at the inlet station 12 and the terminal station 30, the package 2 begins to contact and then begins to loosen its contact with the inlet conveyor 16, respectively.

[0058] Even more specifically, each inlet conveyor 16 may be configured to advance the package 2 at a predetermined, in particular constant, first forward speed.

[0059] More specifically, each outlet conveyor 18 may be configured to advance the package 2 along an outlet path Q, in particular a straight outlet path Q.

[0060] More specifically, the discharge path Q may extend between the start station 31 and the outlet station 13. In particular, at the start station 31 and the outlet station 13, the package 2 begins to contact and then begins to loosen its contact with the outlet conveyor 18, respectively.

[0061] More specifically, each outlet conveyor 18 may be configured to advance the package 2 at a predetermined, particularly constant, second forward speed.

[0062] According to some possible embodiments, the first forward speed and the second forward speed may be equal to each other. According to some other embodiments, the first forward speed and the second forward speed may be different. For example, the first forward speed may be greater than or less than the second forward speed.

[0063] As will be described in more detail, the planar motor 15 may be configured to synchronize the movement of the carrier 14 with respect to the inlet conveyor 16 and the outlet conveyor 18 while advancing the package 2 along at least respective portions of the inlet path P and the outlet path Q.

[0064] Referring particularly to FIGS. 6b - 6c, the planar motor 15 may be configured to control the advancement of each carrier 14 along a receiving path R that is particularly parallel to a part of the inlet path P. Preferably, each carrier 14 may advance through the receiving station 17 when advancing along the receiving path R.

[0065] Furthermore, the planar motor 15 may be configured to control to advance each carrier 14 along the receiving path R at a speed corresponding to the first forward speed.

[0066] Furthermore, while advancing along the receiving path R, each support base 24 of the carrier 14 may be interposed between the planar motor 15 and the respective package 2, that is, the support base 24 may be disposed within the interspace 27. In particular, each support base 24 may be disposed below the respective package 2.

[0067] In this way, it can be ensured that the package 2 is gently placed on each support base 24.

[0068] Referring particularly to FIG. 6a, the planar motor 15 may be configured to position the carrier 14 adjacent to the inlet conveyor 16 when in use, before advancing the carrier 14 along the receiving path R.

[0069] Referring particularly to FIGS. 5a, 5b, 6b and 6c, the control device 26 may be configured to control each holding device 25 from its respective open configuration to its respective holding configuration while each carrier 14 advances along a portion of the receiving path R.

[0070] In particular, the planar motor 15 may be configured to control the advancement of the carrier 14 such that the control device 26 controls the holding device 25 from its open configuration to its holding configuration after the control device 26 has received each package 2.

[0071] More specifically, the control device 26 may be configured to control each holding device 25 to its holding configuration before the package 2 reaches the terminal station 30.

[0072] This ensures that the package 2 remains in contact with the inlet conveyor 16 as long as the package 2 is not securely held by each holding device 25.

[0073] Furthermore, the planar motor 15 may control the advancement of the carrier 14 in a similar manner (but in reverse order) when transferring the package 2 to the outlet conveyor 18.

[0074] More specifically, the planar motor 15 may be configured to control the advancement of each carrier 14 along a discharge path S that is particularly parallel to a portion of the outlet path Q.

[0075] Furthermore, the planar motor 15 may be configured to control the advancement of each carrier 14 along the discharge path S at a speed corresponding to a second advancement speed.

[0076] Furthermore, while advancing along the release path R, each support base 24 of the carrier 14 may be interposed between the planar motor 15 and each package 2, that is, the support base 24 may be disposed within each gap 27.

[0077] Thereby, the packages 2 can be gently removed from their respective support bases 24.

[0078] Furthermore, the control device 26 may be configured to control each holding device 25 from its respective holding configuration to its respective release configuration while advancing each carrier 14 along a part of the release path S.

[0079] In particular, the planar motor 15 may be configured to control the advancement of the carrier 14 such that the control device 26 controls the holding device 25 from the holding configuration to the release configuration before releasing each package 2.

[0080] More specifically, the control device 26 may be configured to control each holding device 25 to the release configuration after the package 2 has been transferred to the outlet conveyor 18.

[0081] More specifically, the planar motor 15 may be configured to selectively control the movement of each carrier 14 independently of the other carriers 14. In this context, independently means that the planar motor 15 can accelerate and decelerate each carrier 14 in a selective manner that can be different from any acceleration and deceleration of the other carriers 14. Furthermore, the planar motor 15 may control the movement of each carrier 14 so as to avoid an undesirable collision with one or more other carriers 14.

[0082] According to some preferred non - limiting embodiments, the planar motor 15 may be configured to control each carrier 14 along three linear axes and around three rotational axes. In other words, each carrier 14 has six degrees of freedom.

[0083] More specifically, the planar motor 15 may be configured to control the movement of each carrier 14 along a first linear axis X, a second linear axis Y perpendicular to the first linear axis X, and a third linear axis Z perpendicular to the first linear axis X and the second linear axis Y. In this way, the positions of each carrier 14 (and each associated package 2) in three-dimensional space can be controlled.

[0084] Furthermore, the planar motor 15 may be configured to control the angular movement of each carrier 14 around a respective first rotation axis, a respective second rotation axis perpendicular to the first rotation axis, and a third rotation axis perpendicular to the first rotation axis and the second rotation axis. Thereby, the angular position of the carrier 14 (and each associated package 2) can be controlled.

[0085] By providing six degrees of freedom, for example, the angular position and spatial position of the package 2 with respect to the planar motor 15 can be accurately controlled.

[0086] Referring particularly to FIG. 2, the planar motor 15 may also include one or more planar control modules 32 operably coupled to the control unit 20 in particular.

[0087] Preferably, the planar control module 32 may include one or more induction coils configured to generate a local electromagnetic field for selectively controlling the forward movement of the carrier 14.

[0088] The control unit 20 may be configured to control a plurality of induction coils to control the movement of the carrier 14 along the first linear axis X, the second linear axis Y, and the third linear axis Z, and around the first rotation axis, the second rotation axis, and the third rotation axis in particular.

[0089] More specifically, the planar motor 15 may be configured to control the carrier 14 along the third linear axis Z so as to lift the carrier 14 from the planar control module 32. In particular, the carrier 14 may be placed on the planar control module 32 with the coil power turned off.

[0090] According to some possible embodiments, when advancing along at least a part of the receiving path R, the planar motor 15 may be configured to move each carrier 14 along the third linear axis Z towards each respective package 2.

[0091] More specifically, the planar motor 15 may be configured to approach each support 24 towards each respective package 2 by arranging a support 24 below each respective package 2 and controlling each carrier 14 along each respective third linear axis Z, and preferably to receive each respective package 2 when each carrier 14 advances along at least a part of the receiving path R.

[0092] According to some possible embodiments, when advancing along at least a part of the release path S, the planar motor 15 may be configured to move each carrier 14 along the third linear axis Z away from each respective package 2.

[0093] More specifically, the planar motor 15 may be configured to withdraw each support 24 from each respective package 2 by controlling each carrier 14 along each respective third linear axis Z, and preferably to release each respective package 2 by moving each support 24 away from each respective package 2 when each carrier 14 advances along at least a part of the release path S.

[0094] Furthermore, each planar control module 32 may extend along a first axis, in particular an axis parallel to the first linear axis X, and a second axis, in particular an axis parallel to the second linear axis Y.

[0095] Preferably, each carrier 14 may include at least one magnetic element and / or ferromagnetic element that enables interaction between a local electromagnetic field generated by the coil and each carrier 14.

[0096] Preferably, the planar motor 15 may include an outer surface 33, particularly a planar outer surface 33, facing the carrier 14. In particular, the outer surface 33 may be in the plane H and may have a (substantially) horizontal orientation, in particular.

[0097] In particular, each planar control module 32 may comprise a respective part of the respective outer surface 33.

[0098] According to some possible embodiments, the inlet path P and / or the outlet path Q may be parallel to the planar motor 15, particularly to the outer surface 33 and / or the plane H.

[0099] Alternatively, at least a part of the inlet path P and / or the outlet path Q may be inclined with respect to the planar motor 15, particularly to the outer surface 33 and / or the plane H. According to such an embodiment, the terminal station 30 and the starting station 31 may be closer to the plane H than the inlet station 12 and the outlet station 13, respectively. In particular, such a configuration may enable the package 2 to be placed and picked up more gently on and from the carrier 14.

[0100] Referring particularly to FIGS. 2, 3 and 7, each of the inlet conveyor 16 and the outlet conveyor 18 may comprise a respective pair of a first belt conveyor 37 and a second belt conveyor 38, particularly each having belts 39 spaced apart from each other. Each pair of the first belt conveyor 37 and the second belt conveyor 38 may be configured to grip the package 2 between each other, particularly between the respective belts 39, and to advance the package 2, particularly by each belt 39 moving along its respective endless path.

[0101] In particular, the distance between each pair of the first belt conveyor 37 and the second belt conveyor 38, particularly the distance between the respective belts 39, may be such that the package 2 can be sandwiched and gripped between each other.

[0102] The respective distances of the first belt conveyor 37 and the second belt conveyor 38 of the inlet conveyor 16 and the outlet conveyor 18 may be different. For example, the planar motor 15 may be configured to correct the orientation of the package 2 by controlling the respective carriers 14 during the forward movement between the inlet conveyor 16 and the outlet conveyor 18. In this case, the distances between the first belt conveyor 37 and the second belt conveyor 38 may be different.

[0103] According to some possible embodiments, the conveying device 11 may include adjusting means for adjusting the distance between the first belt conveyor 37 and the respective second belt conveyors 38.

[0104] According to some possible embodiments, the first belt conveyor 37 and the second belt conveyor 38 may be parallel to the planar motor 15, particularly the outer surface 33 and / or the plane H.

[0105] Alternatively, the first belt conveyor 37 and the second belt conveyor 38 may be inclined with respect to the planar motor 15, particularly the outer surface 33 and / or the plane H, such that the terminal station 30 and the start station 31 are closer to the plane H than the inlet station 12 and the outlet station 13, respectively.

[0106] Particularly referring to FIGS. 3 and 7, the control device 26 may include an inlet cam mechanism 40 configured to control the holding device 26 from its respective open configuration to its respective holding configuration, and an outlet cam mechanism 41 configured to control the holding device 26 from the holding configuration to the open configuration.

[0107] In particular, the inlet cam mechanism 40 and the outlet cam mechanism 41 may be respectively associated with the inlet conveyor 16 and the outlet conveyor 18.

[0108] Preferably, the inlet cam mechanism 40 may be disposed between the inlet station 12 and the terminal station 30, and the outlet cam mechanism 41 may be disposed between the start station 31 and the outlet station 13.

[0109] According to a specific embodiment shown, the inlet cam mechanism 40 and the outlet cam mechanism 41 may be mechanical. Alternatively, the inlet cam mechanism 40 and the outlet cam mechanism 41 may be electronic.

[0110] More specifically, the inlet cam mechanism 40 - is associated with the inlet conveyor 12 and has at least a first inlet cam profile 42 and in particular a second inlet cam profile 43, - is associated with the outlet conveyor 13 and has at least a first outlet cam profile 44 and in particular a second outlet cam profile 45, - a plurality of first cam followers 46, and in particular a plurality of second cam followers 47, each connected to one holding device 25, and may comprise.

[0111] In particular, during use, the interaction of the first cam follower 46, in particular the second cam follower 47, with the first inlet cam profile 42, in particular the second inlet cam profile 43, enables the control of the holding device 25 from its respective open configuration to its respective holding configuration. Further, during use, the interaction of the first cam follower 46, in particular the second cam follower 47, with the first outlet cam profile 45, in particular the second inlet cam profile 46, enables the holding device 25 to be controlled from its respective holding configuration to its respective open configuration.

[0112] More specifically (see FIG. 7), the first inlet cam profile 42 and the first outlet cam profile 44 may be mirror-symmetrical with respect to each other.

[0113] Furthermore, the second inlet cam profile 42 and the second outlet cam profile 45 may be mirror-symmetrical with respect to each other.

[0114] Preferably, the first inlet cam profile 42 and the second inlet cam profile 43 may be equal to each other. Further, the first outlet cam profile 44 and the second outlet cam profile 45 may be equal to each other.

[0115] More specifically, the first inlet cam profile 42 and the second inlet cam profile 43 may preferably be spaced apart from each other in a direction transverse, particularly perpendicular, to the inlet path P, thereby defining a first forward space 48 in which at least a part of the holding device 25 can advance, particularly when the holding device 25 is moved from the open configuration to the holding configuration during use.

[0116] Furthermore, the first outlet cam profile 45 and the second outlet cam profile 46 may preferably be spaced apart from each other in a direction transverse, particularly perpendicular, to the outlet path Q, thereby defining a second forward space 49 in which at least a part of the holding device 25 can advance, particularly when the holding device 25 is moved from the holding configuration to the open configuration during use.

[0117] Preferably, the first inlet cam profile 42 and the second inlet cam profile 43 may be offset relative to each other such that each first cam follower 46 and each second cam follower 47 begin to interact with the first inlet cam profile 42 and the second inlet cam profile 43 simultaneously. Similarly, the first outlet cam profile 44 and the second outlet cam profile 45 may also be offset relative to each other such that each first cam follower 46 and each second cam follower 47 begin to interact with the first outlet cam profile 44 and the second outlet cam profile 45 simultaneously.

[0118] According to some preferred non-limiting embodiments, each one of the first inlet cam profile 42 and the first outlet cam profile 44, particularly the second inlet cam profile 43 and the second outlet cam profile 45, may be S-shaped.

[0121] Referring particularly to FIGS. 3 - 5b, each holding device 25 may include a first holding assembly 55 and a second holding assembly 56 that are spaced apart from each other, and in particular, may thereby define an accommodation space 57 for each respective package 2.

[0122] Preferably, each first holding assembly 55 and each second holding assembly 56 may be configured to engage each respective package 2 from the opposite side thereof with each holding device 25 in a controlled state in each respective holding configuration. Further, each first holding assembly 55 and each second holding assembly 56 may be spaced apart in such a way as to enable each respective package 2 to be placed within and removed from its respective accommodation space 57.

[0123] According to the illustrated embodiments, each first holding assembly 55 and each second holding assembly 56 may be at least partially movable to control each holding device 25 between its respective open configuration and its respective holding configuration.

[0124] Alternatively, only one of each first holding assembly 55 and each second holding assembly 56 may be at least partially movable.

[0125] More specifically, each first holding assembly 55 may include a first engaging portion 58 that is controllable between a retracted position and an engaged position, such that each first engaging portion 58 is retracted from and engaged with a respective package 2.

[0126] Preferably, each second holding assembly 56 may include a respective second engaging portion 59 that is controllable between a retracted position and an engaged position, such that each second engaging portion 59 is retracted from and engaged with a respective package 2.

[0127] Furthermore, with each holding device 25 controlled in a respective open configuration and a respective holding configuration, each first engaging portion 58 and / or each second engaging portion 59 may be in a respective retracted position and a respective engaged position.

[0128] According to some preferred non-limiting embodiments, each first cam follower 46 and each second cam follower 47 may be connected, in particular to a carrier, by one respective first holding assembly 55 and one respective second holding assembly 56.

[0129] More specifically, each first cam follower 46 may be configured to interact with a first inlet cam profile 42 to control a respective first engaging portion 58 from a respective retracted position to a respective engaged position, and to interact with a first outlet cam profile 44 to control the respective first engaging portion 58 from the respective engaged position to the respective retracted position.

[0130] In a similar manner, each second cam follower 47 may be configured to interact with a second inlet cam profile 43 to control a respective second engaging portion 59 from a respective retracted position to a respective engaged position, and to interact with a second outlet cam profile 45 to control the respective second engaging portion 59 from the respective engaged position to the respective retracted position.

[0131] More specifically, referring particularly to FIGS. 4 to 5c, each first holding assembly 55 and each second holding assembly 55 may include a support structure 60 that movably supports each first engaging portion 58 and each second engaging portion 59, respectively.

[0132] In particular, each first engaging portion 58 and each second engaging portion 59 may be connected to their respective support structures 60 in a manner that allows angular movement about their respective axes of rotation. The movement of each first engaging portion 58 and each second engaging portion 59 between their respective retracted positions and engaged positions is obtained by angularly moving each engaging portion 58 and each second engaging portion 59 about their respective axes of rotation.

[0133] Preferably, each first engaging portion 58 and each second engaging portion 59 may include a spring element 61 such that the first engaging portion 58 and the second engaging portion 59 remain in their engaged and retracted positions in the absence of the intervention of the control device 26. In particular, the control device 26 is configured to exert a force that can counteract the force exerted by the spring element 62.

[0134] Referring particularly to FIG. 1, the package filling device 10 may be configured to manufacture a package 2 and fill the package 2 with a dispensed product.

[0135] More specifically, the package filling device 10 may be configured to manufacture the package 2 by forming a tube 62 from a web 3, sealing the tube 62 longitudinally, filling the tube 62 with a dispensed product, sealing the tube 62 transversely, and cutting it.

[0136] In use, the packaging machine 1 manufactures packages 2 filled with a dispensable product.

[0137] In particular, the package filling device 10 forms the package 2 and loads the package 2 into the conveying device 11, and the conveying device 11 conveys the package 2 from the inlet station 12 to the outlet station 13.

[0138] More specifically, the package filling device 10 forms the tube 62 from the web 3, seals the tube 62 longitudinally, forms the tube 62 to obtain the package 2, seals it transversely, and cuts it transversely.

[0139] During the operation of the conveying device 11, the inlet conveyor 16 advances the package 2 along the inlet path P, in particular from the inlet station 12 to the terminal station 30 and / or towards the terminal station 30 from the inlet station 12.

[0140] While each package 2 advances along the inlet station 12, in particular by means of control via the planar motor 15, each carrier 14 is approached such that each support base 24 is interposed between each package 2 while each holding device 25 is in its respective open configuration. Subsequently, each holding device 25 is controlled to its respective holding configuration by the control device 26, in particular by the inlet cam mechanism 40. The latter occurs while each carrier 14 advances along its respective receiving path R.

[0141] When each holding device 25 is controlled to its respective holding configuration, each package 2 can be separated from the inlet conveyor 16. Preferably, while each carrier 14 advances along a part of the receiving path R, the package 2 is in contact with each carrier 14 and the inlet conveyor 16. In particular, after the package 2 has received the terminal station 30, the package 2 loses contact with the inlet conveyor 16 and advances further independently by the advancement of each carrier 14.

[0142] Preferably, before each holding device 25 is controlled to its respective holding configuration, each carrier 14 is moved towards each package 2 along a third linear axis Z by the planar motor 15 so as to bring each package 2 into contact with each support base 24.

[0143] Furthermore, the carrier 14 continues to advance to transfer each package 2 to the outlet conveyor 18. The carrier 14 may advance each package 2 directly or indirectly (e.g., first to station 29) to the outlet conveyor 18.

[0144] Each package 2 contacts the outlet conveyor 18 at the start station 31 while remaining in contact with its respective carrier 14.

[0145] While each carrier 14 travels along the discharge path S, the control device 26, in particular the outlet cam mechanism 41, controls each holding device 25 from its respective holding configuration to its respective release configuration. Thereafter, the carrier 14 is withdrawn from each package 2, and this package 2 advances alone to the outlet station 13 by the discharge conveyor 18.

[0146] Preferably, after controlling each holding device 25 to its respective release configuration, each carrier 14 is moved away from its respective package 2 along a third linear axis Z by the planar motor 15.

[0147] The advantages of the conveying device 11 and / or the packaging machine 1 according to the present invention will be apparent from the foregoing description.

[0148] In particular, the conveying device 11 can advance the package 2 in a flexible manner.

[0149] Furthermore, with the conveying device 11, the package 2 can be handled flexibly and expandably downstream of the package filling device 10.

[0150] Furthermore, the conveying device 11 can process different types of packages 2 without requiring time-consuming changes.

[0151] However, it is obvious that modifications may be made to the conveying device 11 and / or the packaging machine 1 and / or the carrier 14 described herein without departing from the scope of protection defined in the appended claims.

[0154] Furthermore, the planar motor 15 may be configured to control the advancement of each first carrier portion and each second carrier portion so as to control each holding device 25 between the open configuration and the holding configuration by controlling the relative position between each first carrier portion and each second carrier portion. Preferably, the planar motor 15 may advance each first carrier portion and each second carrier portion independently of each other but in cooperation so that each first carrier portion and each second carrier portion can receive, advance, and release the respective package 2.

[0155] Furthermore, each first carrier portion and each second carrier portion may respectively carry a respective first holding assembly 55 and a respective second holding assembly 56.

[0156] Furthermore, each holding device 25 can be controlled to its respective holding configuration by bringing each first carrier portion and each second carrier portion closer to each other, and can be controlled to its respective open configuration by separating each first carrier portion and each second carrier portion from each other.

[0157] More specifically, each first carrier part and each second carrier part may comprise at least one magnetic element and / or ferromagnetic element enabling interaction with the local electromagnetic field generated by the coil.
