Description

[0001] The present invention relates to a packaging device and a method for packaging articles.

[0002] Handling or handling articles often requires providing individual or multiple articles with packaging, which can be in the form of a container or wrapping. Such packaging is used to group articles together into a packaging unit, as which the articles are transported to a desired destination and, if applicable, put on sale. Packaging also often serves the purpose of protecting multiple articles from damage during transport. This is particularly the case when the packaging is in the form of a cardboard box in which several articles are completely contained. Such packaging units therefore provide an effective way of enabling simultaneous handling of several articles, in particular to facilitate the transport of several articles.

[0003] Folding boxes are often used as packaging for multiple items because they offer good protection for the items they contain, can be stacked with the items inside, and also allow the items they contain to be identified by information printed or glued on their outside.

[0004] Once the multiple items have been placed into a respective package, thus forming a packaging unit, the packaging units are first transferred to a conveyor belt and then fed to a divider, which places successive packaging units at a relative distance from one another suitable for further processing. Before being fed to the divider, it may be necessary for the packaging units to be first accumulated in order to feed them to the divider in an orderly manner.

[0005] Once the packaging units have been placed at a relative distance from one another via the divider, the packaging units can then be passed on to another work station, such as a grouping station, in this relative distance.

[0006] To form packaging units and subsequently transfer them to a specific relative spacing, packaging devices are required that have a complex design and require a lot of space. It would also be desirable if the performance and throughput of such devices and processes could be further increased.

[0007] An object of the invention can therefore be seen in providing a generic device and a generic method that require less space. Furthermore, a generic packaging device and a generic method that are characterized by higher throughput and higher performance, respectively, are to be provided.

[0008] The problem is solved by the subject-matter comprising the features in the independent claims.

[0009] The invention relates to a packaging device. The packaging device comprises at least one horizontal conveyor for providing packaging. In various embodiments, the packaging device can comprise a first horizontal conveyor and a second horizontal conveyor. A conveying direction of the first horizontal conveyor and a conveying direction of the second horizontal conveyor can be oriented opposite to one another. In addition, the packaging device can comprise at least one transfer unit designed to transfer packaging from the first horizontal conveyor to the second horizontal conveyor.

[0010] The packaging device may comprise a plurality of shuttles, each of which is configured to receive a respective package. The at least one horizontal conveyor may be configured to convey or transport the plurality of shuttles. As already mentioned above, the packaging device may comprise at least one transfer unit. The at least one transfer unit may be configured to transfer shuttles from the first horizontal conveyor to the second horizontal conveyor.

[0011] The packaging may be cartons or boxes designed to hold multiple items and have a lid or top that can be folded in and closed. The packaging may also be trays with multiple flaps that can be folded in and converted into an upright orientation.

[0012] The packaging may also be packaging which can each contain several articles designed as a beverage bottle and which, for this purpose, has an opening for each beverage bottle through which the respective beverage bottle can be inserted.

[0013] The packaging device further comprises an infeed for articles. The infeed can have several lane plates, with articles being guided along a respective row between immediately adjacent lane plates. Furthermore, the infeed can comprise a conveyor belt for moving the articles or for moving the articles along a respective row.

[0014] When referring to articles in this case, this can in principle be understood to mean any object that is to be combined with packaging via the packaging device or that is to be packaged with a respective packaging via the packaging device. In particular, the articles can be beverage containers, beverage cans, and / or beverage bottles.

[0015] The packaging device comprises a handling device which is designed to receive articles from the inlet and to combine them with a respective packaging on the at least one horizontal conveyor device, so that a plurality of articles with a respective packaging form a respective packaging unit on the at least one horizontal conveyor device.

[0016] In various embodiments, the handling device can be designed for inserting articles into a respective package, which package is located on the horizontal conveyor. If the packaging device comprises multiple shuttles, the handling device can be designed for inserting articles into a respective package, which package is accommodated by a respective shuttle.

[0017] The handling device may also be designed to pneumatically receive articles from the infeed by applying negative pressure to the articles and to combine them with a respective packaging on the at least one horizontal conveyor. In further embodiments, the handling device may also comprise a plurality of clamping and / or gripping instruments, by means of which clamping and / or gripping instruments the handling device can receive articles from the infeed. The handling device may, for example, comprise a gantry system or be designed as a gantry system. The handling device may also be designed as a multi-axis robot or as an articulated-arm robot or comprise a multi-axis robot or an articulated-arm robot.

[0018] The packaging device comprises a manipulator and a transport device. The transport device can, for example, have a circulating conveyor belt or a circulating mat chain for conveying packaging units.

[0019] The manipulator is designed to receive packaging units from the at least one horizontal conveyor device and to transfer the received packaging units to predetermined positions on the transport device, in which predetermined positions successive packaging units on the transport device have a defined relative spacing from one another.

[0020] In particular, the packaging device may comprise a specific manipulator which is designed to receive packaging units from the at least one horizontal conveyor device and to transfer the received packaging units to predetermined positions on the transport device, in which predetermined positions successive packaging units have a defined relative spacing from one another.

[0021] Since the manipulator itself can transfer packaging units to the transport device with a defined relative spacing, a divider can be omitted in various designs to ensure that packaging units are spaced at a defined relative distance from one another or to be able to feed packaging units to a subsequent workstation in a timed manner. The packaging device therefore has a simple and compact design. Furthermore, the packaging device can be used to package items at high throughput and bring them into the timed alignment required for subsequent processing.

[0022] As will be mentioned below, in various embodiments, the transport device can comprise a plurality of rotating push rods. However, in various embodiments, such a plurality of rotating push rods may not be provided, and the transport device may advance the packaging units transferred to the predetermined position(s) in a linear direction, with the packaging units maintaining the defined relative spacing from one another.

[0023] The predetermined positions can be designed such that the relative spacings formed between immediately successive packaging units on the transport device are substantially identical.

[0024] As previously mentioned, the transport device can comprise a plurality of rotating push rods, of which immediately successive push rods form a respective free space between them, wherein a respective predetermined position is located in a respective free space when the manipulator transfers the respective received packaging unit to the transport device.

[0025] . At least two closed chain and / or belt drives can be provided, which are guided essentially parallel to one another and on which the plurality of push rods are arranged for circulating movement.

[0026] When referring to multiple rotating push rods, this can be understood as elements that are in contact with the back of packaging units while the packaging units are moved along a conveyor belt. Therefore, in various embodiments, it is not necessary for the packaging units to be subjected to force or actively conveyed via the multiple rotating push rods.

[0027] Push rods can also be designed in such a way that they convey or push packaging units under force while resting against the rear, while the packaging units rest on a transfer plate and are moved in a sliding manner along the transfer plate. Push rods can also be understood as elements that rest against the packaging units at the front and at least temporarily decelerate the packaging units relative to the transport speed of a conveyor belt on which the packaging units rest, in order to create a defined relative distance between successive packaging units.

[0028] It may be that no conveyor belt is arranged between the at least one horizontal conveyor device and the transport device. It may therefore be that the manipulator is arranged directly downstream of the at least one horizontal conveyor device, and that the transport device immediately follows the manipulator.

[0029] The manipulator can thus transfer packaging units from the at least one horizontal conveyor to the transport device.

[0030] In such embodiments, already formed packaging units are therefore received directly by the manipulator from the at least one horizontal conveyor and placed into the free spaces. In these embodiments, no further or additional conveyor belts are required to transfer already formed packaging units to the conveyor or to the divider. The packaging device therefore requires relatively little space to form packaging units and to transfer the formed packaging units into the corresponding arrangement with a predetermined relative spacing. Since no further conveyor belt or work station is arranged between the at least one horizontal conveyor and the manipulator, the packaging device can also operate at a high throughput or high performance.

[0031] For example, the transport device or divider can be followed by a work station where thermoplastic packaging material is applied to packaging units. For this purpose, the work station can comprise several circulating wrapping rods. The packaging device can also comprise a shrink tunnel through which the thermoplastic packaging material is shrunk onto the packaging units. The transport device or divider can also be followed by a grouping station where the packaging units are arranged relative to one another. This relative arrangement is coordinated with a palletizable layer to be formed from the packaging units.

[0032] The at least one manipulator may be configured to lift packaging units from the at least one horizontal conveyor and to insert the lifted packaging units into free spaces. In such embodiments, the throughput or performance can be further increased. Alternatively, the manipulator may be configured to push packaging units from the at least one horizontal conveyor into the free spaces.

[0033] Furthermore, the infeed for articles and the transport device may share a common conveyor belt. Such packaging devices have a simple design.

[0034] It has also proven effective if the relative distance between the at least one horizontal conveyor and the transport device is less than 5 meters. Such embodiments are characterized by a further reduced space requirement and high performance or throughput, since the manipulator only has to travel a short distance when transferring packaging units from the at least one horizontal conveyor to the transport device.

[0035] In various embodiments, the push rods of the transport device can be redirected below a transport plane designed for the packaging units. This can prevent the manipulator from accidentally colliding with the redirected part of the push rods, which could potentially cause damage. Furthermore, very large manipulators can be used in such embodiments, as a collision with the redirected part of the push rods can be ruled out.

[0036] The manipulator may be configured to receive multiple packaging units and adjust the relative spacing of the multiple received packaging units. This allows the packaging units to be inserted into the spaces formed between push rods in a predetermined position without the relative spacing of the packaging units being adjusted beforehand using additional devices.

[0037] Furthermore, the packaging device can comprise an actuator provided for the circular movement of the push rods and a control device connected to the actuator, via which the actuator can be controlled for the continuous circular movement of the push rods.

[0038] In various embodiments, the handling device and the at least one horizontal conveyor device can be designed as a component of a packaging module of the packaging device, which packaging module comprises a frame which forms the periphery, wherein the frame extends over the plurality of circumferentially moving push rods of the transport device.

[0039] In such embodiments, the push rods may be retracted above the frame. Even with such embodiments, it is possible to prevent the manipulator from accidentally colliding with the retracted part of the push rods, which could potentially cause damage.

[0040] Furthermore, the manipulator can comprise a gripper head for receiving packaging units. This gripper head is designed such that it can be inserted into an area formed between the forward and return strands of the circumferentially guided push rods. The gripper head can be cantilevered or extend laterally beyond a support structure of the manipulator provided for the gripper head.

[0041] The invention also relates to a use of a packaging device according to one of the previously described embodiments for articles which are beverage bottles or beverage cans.

[0042] The invention further relates to a method for packaging articles. The invention can relate to a method for packaging articles using an embodiment of the packaging device already described above. The embodiments of the packaging device already described above can also be designed to carry out the embodiments of the method according to the invention described below. Features which have already been mentioned previously for various embodiments of the packaging device can also be provided in the embodiments of the method according to the invention described below, without being mentioned again. Likewise, the features described below for the embodiments of the method according to the invention can be provided in the embodiments of the packaging device according to the invention already described above.

[0043] The articles may be beverage containers, beverage bottles, or beverage cans. However, the invention is not limited to such articles, so the articles may also be other objects, either already packaged or not yet packaged.

[0044] Packaging is provided via at least one horizontal conveyor. Furthermore, a handling device receives articles from an infeed and combines the articles with a respective packaging on the at least one horizontal conveyor, so that several articles with a respective packaging form a respective packaging unit on the at least one horizontal conveyor.

[0045] A transport device is also provided. In the method, the manipulator or a specific manipulator receives packaging units from the at least one horizontal conveyor and transfers the received packaging units to predetermined positions on the transport device. In these predetermined positions, successive packaging units are located on the transport device at defined relative distances from one another.

[0046] The transport device may comprise several push rods that are moved in a rotating manner, with immediately consecutive push rods forming a respective free space between them. A respective predetermined position may be located in a respective free space when the manipulator transfers the respective received packaging unit to the respective predetermined position on the transport device.

[0047] The manipulator may lift packaging units from the at least one horizontal conveyor and then place the lifted packaging units into the free spaces.

[0048] Furthermore, it may be the case that articles are moved in the infeed area via a circulating driven conveyor belt, whereby this circulating driven conveyor belt moves packaging units in the area of ​​the transport device, whereby each packaging unit is in contact with a respective push rod at the rear during the movement.

[0049] The manipulator can also move packaging units from receipt to placement in the free spaces along a transfer path that is no longer than 5 meters.

[0050] It may be that the push rods of the transport device are returned below a transport level designed for the packaging units.

[0051] It is also conceivable that the manipulator jointly receives several packaging units from the at least one horizontal conveyor and adjusts the relative distance of the received packaging units in accordance with the specified positions or in accordance with the positions of the free spaces.

[0052] Furthermore, the several push rods of the transport device can be driven continuously.

[0053] It may also be the case that the at least one horizontal conveyor device and the handling device are a component of a packaging module, which packaging module comprises a frame which forms the periphery of the packaging module and extends over the plurality of circumferentially moved push rods, wherein the push rods are returned above the frame.

[0054] Furthermore, it has proven useful if the manipulator comprises a gripper head via which the manipulator receives packaging units from the at least one horizontal conveyor device, wherein the gripper head is inserted into an area formed between the forward run and return run of the circulating push rods in order to introduce the received packaging units into the free spaces.

[0055] In the following, exemplary embodiments will explain the invention and its advantages in more detail with reference to the accompanying figures. The relative sizes of the individual elements in the figures do not always correspond to the actual sizes, as some shapes are simplified and others are enlarged relative to other elements for better illustration. Fig. 1 shows a schematic view of an embodiment of a packaging system according to the invention. Fig. 2 shows the embodiment of the packaging system according to Fig. 1 and illustrates in conjunction with Fig. 1 individual aspects of its functioning. Fig. 3 shows a schematic view of an embodiment of a packaging system according to the invention with a mechanism for pushing shuttles between two horizontal conveyors. Fig. 4 shows steps as they can be carried out individually or according to the Fig. 4 can be provided in various embodiments of the method according to the invention.

[0056] Identical reference numerals are used for identical or equivalently functioning elements of the invention. Furthermore, for the sake of clarity, only those reference numerals are shown in the individual figures that are necessary for the description of the respective figure. The illustrated embodiments merely represent examples of how the invention can be configured and do not constitute an exhaustive limitation.

[0057] The schematic top view of the Fig. Figure 1 illustrates a first embodiment of a packaging device according to the invention, which is generally designated here by reference numeral 1. Articles 2, which in this case are or can be formed by beverage containers 4, can be packaged via the packaging device 1. The packaging device 1 comprises a first horizontal conveyor 10 and a second horizontal conveyor 20, which are arranged side by side.

[0058] The first horizontal conveyor 10 has a plurality of circumferentially guided holding means 12, wherein a shuttle 5 can be clamped to the first horizontal conveyor 10 between each two immediately consecutive holding means 12 of the first horizontal conveyor 10. For example, the first horizontal conveyor 10 can comprise at least one circumferentially guided chain and / or belt drive on which the holding means 12 are arranged.

[0059] In the Fig. 1, shuttles 5 are returned from the second horizontal conveyor 20 to the first horizontal conveyor 10, wherein the Fig. 1 shuttle 5 which has not yet completely transferred to the second horizontal conveyor 20 in Fig. 2 have already completely changed from the second horizontal conveyor 20 to the first horizontal conveyor 10 and are held clamped between immediately successive holding means 12 of the first horizontal conveyor 10.

[0060] The reference number 30 denotes in the Fig. 1 and Fig. 2 each have a magazine or a first magazine in which a plurality of packages 3 are accommodated. The packages 3 are removed from the magazine 30 by means of a handling device (not shown) and received by the shuttles 5, which are further clamped to the first horizontal conveyor 10 via the holding means 12.

[0061] In the magazine 30, the packages 3 are still folded. During transfer to the first horizontal conveyor 10 or during transfer to the shuttles 5 moved by the first horizontal conveyor 10, the packages 3 are pulled up by means of the handling device. Furthermore, the shuttles 5 moved by the first horizontal conveyor 10 are moved continuously in a transport direction TR1 while the then pulled-up packages 3 are deposited on the shuttles 5. This transport direction TR1 is provided by the first horizontal conveyor 10 for moving the shuttles 5 and for moving the packages 3 picked up and pulled up by the shuttles 5.

[0062] The representation of the Fig. 1 also shows that the dimensions of the shuttles 5 are adapted to the dimensions of the mounted packages 3, or that the dimensions of the shuttles 5 correspond to the dimensions of the mounted packages 3. The shuttles 5 each form an edge region over which the mounted packages 3 can be held in a form-fitting or essentially form-fitting manner after each acceptance by a respective shuttle 5.

[0063] The packaging device 1 also comprises a second magazine 40, in which a plurality of compartments 6 are accommodated. The compartments 6 are removed from the second magazine 40 and inserted into the packages 3 that are still arranged and pulled onto the shuttles 5. The removal of compartments 6 from the second magazine 40 and the arrangement of removed compartments 6 in the pulled-up packages 3 can be carried out via the handling device already described above, which removes outer packages 3 from the first magazine 30, pulls them up, and places them on the shuttles 5.

[0064] It is also conceivable that a further handling device is provided for this purpose, which removes compartments 6 from the second magazine 40 and inserts them into the packages 3 that have already been pulled up and are still located on shuttles 5 moved by means of the first horizontal conveyor device 10.

[0065] By means of the respective compartment 6, a plurality of chambers are formed in the respective packaging 3, wherein each chamber is provided for receiving a respective article 2 designed as a beverage container 4. While a respective compartment 6 is introduced into a respective packaging 3, the respective packaging 3 and the respective shuttle 5, on which the respective packaging 3 continues to stand, are moved continuously along the first transport direction TR1.

[0066] After a respective compartment 6 has been introduced into a respective packaging 3, the respective packaging 3, together with the respective shuttle 5, on which the respective packaging 3 continues to stand, changes from the first horizontal conveyor device 10 to the second horizontal conveyor device 20. For this purpose, immediately after the introduction of a respective compartment 6 into a respective packaging 3, a sliding bar may come into surface contact with a plurality of shuttles 5 and / or with a plurality of packages 3, into which a respective compartment 6 has already been introduced, and pushes the plurality of shuttles 5 and the packages 3 still arranged thereon perpendicular to the first transport direction TR1, so that the respective shuttles 5 and the packages 3 still arranged thereon are moved in the direction of the second horizontal conveyor device 20 or are pushed in the direction of the second horizontal conveyor device 20.

[0067] Since such a sliding bar must be moved back in the direction of the first horizontal conveyor device 10 to receive another shuttle and since this limits the throughput for the packaging device 1, embodiments have proven successful in which such a sliding bar can be dispensed with.

[0068] Instead of such a sliding bar, a transfer unit 78 (cf. Fig. 3) may be provided, with which the shuttles 5 can change from the first horizontal conveyor 10 to the second horizontal conveyor 20 or via which the shuttles 5 can change from the second horizontal conveyor 20 to the first horizontal conveyor 10. In such embodiments according to the following description to Fig. 3, the packaging device 1 can be operated with high throughput.

[0069] The second horizontal conveyor device 20 also has a plurality of holding means 14 which clamp a respective shuttle 5 after it has changed from the first horizontal conveyor device 10 to the second horizontal conveyor device 20.

[0070] A further component of the packaging device 1 is formed by an inlet 60 with a conveyor device 64 and a plurality of parallel lane plates 62, between which a plurality of parallel lane plates 62 are guided parallel to one another. A respective foremost article 2 or a respective foremost beverage container 4 of a respective row is in surface contact with a support beam 9.

[0071] The support beam 9 is moved parallel to a second transport direction TR2, along which second transport direction TR2 the second horizontal conveyor 20 moves shuttles 5 with packages 3 still arranged thereon, each of which already has a compartment 6 inserted. A movement speed of the support beam 9 is reduced compared to a transport speed of the conveyor 64 formed as a component of the inlet 60, so that articles 2 of a respective row or beverage containers 4 of a respective row accumulate on the support beam 9.

[0072] A handling device designated by reference numeral 15 and shown or indicated only schematically here receives several articles 2 or several beverage containers 4 of the parallel rows from the inlet 60 and subsequently deposits one article 2 or one beverage container 4 in each case in a respective chamber formed by the compartment 6 in a packaging 3. The articles 2 or the beverage containers 4 are then received in a form-fitting or essentially form-fitting manner in the chambers formed by the respective compartment 6 of a respective packaging 3.

[0073] During the placement of the articles 2 or the beverage containers 4 in the respective chamber, the respective shuttle 5, which has already been transferred to the second horizontal conveyor 20, is moved continuously along the second transport direction TR2 together with the packaging 3 still standing thereon and the compartment 6 inserted therein. The respective shuttle 5, which has already been transferred to the second horizontal conveyor 20, continues to be held clamped to the second horizontal conveyor 20 via the holding means 14 of the second horizontal conveyor 20.

[0074] A packaging 3 forms a packaging unit 8 together with the inserted compartment 6 and the inserted articles 2 or the inserted beverage containers 4. A respective packaging unit 8, which is still picked up by a shuttle 5, is then picked up by a manipulator 16, which Fig. 1 and Fig. 2 is only shown schematically.

[0075] In the embodiment according to Fig. 1 and Fig. 2, the manipulator 16 simultaneously or at least approximately simultaneously receives six packaging units 8 from six shuttles 5 and lifts these six packaging units 18 from the shuttles 5 located on the second horizontal conveyor 20. In order to receive the packaging units 8, the manipulator 16 has a gripper head that clamps and / or pneumatically grasps the packaging units 8. After receiving the six packaging units 8, the manipulator 16 performs a transfer movement for the six packaging units 8, with which the manipulator 16 moves the six packaging units 8 to a transport device 70.

[0076] The transport device 70 has several circumferentially guided push rods 7 and a conveyor belt 72. Between each pair of immediately consecutive push rods 7, a respective free space is formed, which in Fig. 1 and Fig. 2 is indicated by an arrow and to which free space is referred to with reference number 13. When the manipulator 16 has received packaging units 8 from the shuttles 5, the manipulator 16 adjusts the relative distance between the packaging units 8 so that two packaging units 8 can subsequently be placed in each free space 13.

[0077] The manipulator 16 therefore transfers received packaging units 8 to predetermined positions on the transport device 70, in which predetermined positions the packaging units 8 already have a defined relative spacing from one another. In the embodiment according to Fig. 1, a respective predetermined position is located in a respective free space 13 when the manipulator 16 transfers the respective received packaging unit 8 to the transport device 70.

[0078] The push rods 7 can also be omitted in further embodiments. In such embodiments, the manipulator 16 can continue to receive the packaging units 8 from the second horizontal conveyor 20 and transfer them to the transport device 70 in the predetermined positions, so that the packaging units 8 transferred to the transport device 70 form a defined relative spacing from one another.

[0079] It has proven advantageous if the relative spacing between successive packaging units 8 is essentially identical. If the transport device 70 is driven at a constant conveying speed over time, the packaging units 8 can be fed to a subsequent work station in cycles or at a predetermined timing.

[0080] During the placement of the packaging units 8 in the free spaces 13 or after the packaging units 8 have been placed in the free spaces 13, the push bars 7 come into contact with the rear of the packaging units 8 and accompany the packaging units 8 while supporting them from behind. The packaging units 8 are conveyed via the conveyor belt 72 of the transport device 70, on which the packaging units 8 rest.

[0081] The push bars 7 are moved in a rotating manner, whereby an actuator (not shown) is provided for this purpose, which drives the push bars 7 in a rotating manner. The control device S ensures that the rotating movement of the push bars 7 takes place continuously or without interruption.

[0082] In practice, the distance between the transport device 70 and the second horizontal conveyor 20 is less than 5 meters. This allows very high cycle times to be achieved, within which the manipulator 16 receives packaging units 8 from the shuttles 5 and places them in the free spaces 13.

[0083] To avoid a collision of the manipulator 16 with the push beams 7, embodiments have proven effective in which the push beams 7 are returned below a transport plane provided by the conveyor belt 72 for conveying the packaging units 8. Alternatively, the push beams 7 can be returned above a frame of the transport device 70, thereby providing sufficient space for the manipulator 16 to be inserted into an area formed between the forward and return strands of the circulating push beams 7.

[0084] As already mentioned above, the inlet 60 forms a conveyor device 64. In various embodiments, the conveyor device 64 can be omitted if the conveyor belt 72 is designed as a common conveyor belt for the inlet 60 and the conveyor device 70 and extends along the inlet 60 and along the conveyor device 70. In such embodiments, the conveyor belt 72 or the common conveyor belt can move both articles 2 in the area of ​​the inlet 60 and packaging units 8 in the area of ​​the conveyor device 70.

[0085] In the embodiment according to Fig. 1 and Fig. 2, the packages 3 and the packaging units 8 are moved via two horizontal conveyor devices 10 and 20, with the packages 3 being arranged on shuttles 5. However, it is also possible that only one horizontal conveyor device 10 or 20 is provided, with which packages 3 are conveyed. It is also possible that packages 3 are conveyed with only one horizontal conveyor device 10 or 20 or with several horizontal conveyor devices 10 or 20, without the movement or conveyance being carried out with the aid of shuttles 5.

[0086] The packaging units 8 are conveyed toward another work station via the transport device 70. Thus, in a subsequent step, thermoplastic packaging material may be applied to the packaging units 8 and shrunk onto the packaging units 8 in a shrink tunnel. The packaging units 8 may also be moved toward a grouping station via the transport device 70, which arranges the packaging units 8 relative to one another in a manner that is coordinated with a palletizable layer to be formed from the packaging units 8.

[0087] The Fig. 1 shows, with reference number 5', empty shuttles from which the packaging units 8 have already been removed via the manipulator 16. The empty shuttles 5' are returned to the first horizontal conveyor 10 for the renewed receipt of packages 3. For this purpose, a sliding bar can again come into surface contact with the empty shuttles 5' and push the empty shuttles 5' from the second horizontal conveyor 20 onto the first horizontal conveyor 10. However, it has proven useful if at least one transfer unit 78 (cf. Fig. 3) is provided.

[0088] A summary of the Fig. 1 and Fig. 2 illustrates the change of the shuttles 5 together with the packaging 3 located thereon and the inserted compartments 6 from the first horizontal conveyor 10 to the second horizontal conveyor 20. A summary of the Fig. 1 and Fig. 2 the return of empty shuttles 5' from the second horizontal conveyor 20 to the first horizontal conveyor 10.

[0089] From a summary of the Fig. 1 and Fig. 2 it is also clear that the first horizontal conveyor device 10 and the second horizontal conveyor device 20 are connected via transfer units 78 (cf. Fig. 3 and Fig. 4) work according to the principle of a rotary machine and guide the shuttles 5 in rotation.

[0090] The Fig. Figure 3 shows a functional principle as it can be provided in various embodiments of a packaging device 1 according to the invention and shows in particular an embodiment of a transfer unit 78. Further clarified Fig. 3 individual steps as they occur in various embodiments of the method 100 according to the invention (cf. Fig. 4) may be provided.

[0091] For reasons of clarity, the functional principle and the operation of the packaging device 1 in Fig. 3, only the first horizontal conveyor 10, the second horizontal conveyor 20, the holding means 12 and 14, and gears 50 are shown, which can push a respective shuttle 5 from the first horizontal conveyor 10 to the second horizontal conveyor 20 and from the second horizontal conveyor 20 to the first horizontal conveyor 10. The transport device 70, the infeed 60, the handling device 15, the manipulator 16, as well as the first magazine 30 and the second magazine 40 are missing from the illustration according to Fig. 3, however, are for the functional principle or the operation of the packaging device 1 according to Fig. 3 is also provided.
