Description

Technical Field

[0001] The invention relates to a stacking platform, in particular a stacking device for stacking bags. Depending on the design, at least one bag layer can be constructed on such a stacking platform and then pushed onto a pallet or the like. For this purpose, the stacking platform comprises at least one stacking device, at least one displacement device and at least one air supply device, wherein the stacking device is configured so that it can be moved at least between a closed position and an open position by means of the displacement device. The upper side of the stacking device comprises at least one stacking surface for receiving at least one bag layer, wherein the stacking device is configured so that air can flow through it at least partially. For this purpose, at least one air supply opening is provided on the lower side of the stacking device, and the stacking surface has at least one air outlet, wherein the air supply device comprises an air guide element with at least one air outlet and at least one connecting device. Therefore, the connecting device is arranged between the air outlet of the air guide element and the air supply opening of the stacking device. The invention also relates to a stacking device for stacking items, in particular bags or filled bags, in particular bags filled with items, comprising at least one conveying device having at least one conveying element for conveying items and at least one such stacking platform. Background Art

[0002] So-called palletizing devices are often connected downstream of packaging plants, which for example pack items into bags, and which stack the filled bags in specific layers on pallets. This ensures that the filled bags or other items are optimally transported further in accordance with the plant in question.

[0003] For palletizing filled bags, a specific layer of a specific number of bags is arranged in a specific arrangement on a so-called stacking table and stacked on a pallet underneath, for example by pulling open the stacking table.

[0004] In order to prevent the bags from deforming when being pushed away and to simplify the pushing away process overall, in the case of known palletizing devices, an air flow is generated between the stacking platform and the bags according to the design, so that the bags can be pushed away or slided from the supporting surface.

[0005] Depending on the design, air is introduced for this purpose into the partially hollow stacking platform, wherein the air escapes through openings in the supporting surface and thus forms an air cushion beneath the bag layer.

[0006] In order to introduce air into the stacking platform, in the known palletizing devices, an air hose is provided, which is arranged on the stacking platform in the manner of a swing (bird cage). When the stacking platform is moved forwards and backwards or when the bag layer is pushed onto the pallet, the required length differences and / or angular offsets are compensated.

[0007] However, a disadvantage of this design is that the swing requires considerable installation space. Furthermore, care must be taken to ensure that the hose does not collide with the conveyor device that transports the bags to the stacking station when moving back and forth. As a result, the operation of the stacking device could be affected or damaged. In addition, the relatively large movement paths in some cases also lead to relatively rapid wear of the air hose. Summary of the invention

[0008] The object of the invention is therefore to provide a stacking station in which the bag layers can be pushed out more easily by means of an air cushion beneath the bags, wherein however the smallest possible space is required in terms of construction for this purpose and reliable operation is ensured.

[0009] This object is achieved by a stacking station having the features of claim 1 and a palletizing device having the features of claim 15. Preferred developments of the invention are the subject matter of the respective dependent claims. Further advantages and features of the invention are apparent from the summary of the invention and the detailed description.

[0010] The stacking platform according to the invention can be used in particular for a stacking device or a stacking device for stacking bags separately, and comprises at least one stacking device, at least one displacement device and at least one air supply device. Therefore, the stacking device is configured to be moved at least between a closed position and an open position by means of a displacement device. In addition, the upper side of the stacking device comprises at least one stacking surface for receiving at least one bag layer, wherein the stacking device is configured so that air can flow through it at least partially. At least one air supply port is provided on the lower side of the stacking device, and the stacking surface has at least one exhaust port. The air supply device comprises at least one air guiding element having at least one air outlet and at least one connecting device. Therefore, the connecting device is suitable and configured to achieve a length compensation substantially in a plane between the air outlet and the air supply port when the stacking device is moved.

[0011] In particular, the air supply device may form an air cushion under the bags arranged on the stacking device to reduce the friction coefficient so that the bags will not be deformed when the stacking device is pulled open or opened.

[0012] For this purpose, the stacking platform or stacking device is ventilated from the inside. Therefore, no significant pressure is generated by this ventilation. In particular, it is preferred to use a simple blower.

[0013] In order to design the stacking device to be movable, the displacement device comprises in particular at least one rail system, on which the plate or the stacking device can be moved, for example by means of a belt drive.

[0014] In particular, a large number of air outlets are provided in the stacking device or the stacking surface in order to provide air for forming the air cushion over a large part of the surface, in particular the entire surface, of the stacking platform or the stacking device.

[0015] In the closed position of the stacking device, at least one pallet can preferably be arranged below the stacking table or below the stacking device, onto which pallet the bag layers arranged on the stacking device are stacked or pushed when the stacking device is opened.

[0016] The closed or extended position of the stacking device is thus a position in which the pallet is covered under the stacking platform. In this position, the bag layer is located on the stacking device. The open position is thus a position in which the stacking device is retracted or moved back so that the pallet under the stacking platform is freed to push the bags onto the pallet.

[0017] The stacking platform according to the invention has many advantages. One significant advantage is that an air cushion can be provided for easily pushing apart the bag layer to reduce friction so that the bag will not be deformed when being pushed onto a pallet or the like.

[0018] Due to the design according to the invention, this can all be achieved in a very flat structure, so that the remaining assembly space is not affected. Otherwise, conventional air hoses would be required, which are additionally provided in the manner of a so-called swing or birdcage in order to be able to achieve longer travel distances. However, long travel distances often lead to a lot of wear and tear, and also to collisions with, for example, the lower rails of a conveyor device that transports the bags to the stacking table. In particular, in this way, the stacking table can be moved between the upper and lower rails of the conveyor element, which allows the transfer height from the conveyor device to the stacking table to be smaller. Depending on the design, larger height offsets here can lead to deformations of the bags when they are transported and worsen the stacking arrangement of the bags on the pallet.

[0019] Preferably, the connecting device is at least partially telescopically designed. Telescopic or telescopic is therefore particularly understood to mean that when the stacking device is moved, a length compensation is achieved between the air outlet and the air supply opening.

[0020] The air-guiding element is preferably arranged to be fixed. This can facilitate a secure and stable placement of the air-guiding element and can also provide a very flat design.

[0021] The connecting device is preferably located substantially on a plane parallel to the stacking device.Therefore, in particular, the connecting device is arranged substantially parallel to the stacking surface or parallel to the underside.

[0022] Preferably, the connecting device is constructed substantially rigidly, in particular so that it cannot sag or be set in a so-called swinging motion.

[0023] In an advantageous design, the connection device is rotatably connected to the air outlet of the air guide element and / or the air supply of the stacking device, in particular by means of at least one pneumatic rotary feedthrough, respectively. Thus, despite the use of rigid components, a displacement of the stacking device can be achieved due to the rotatable design of the connection of the connection device and the fact that the connection device is substantially designed in such a telescopic manner.

[0024] In a preferred further development, the connecting device is arranged substantially transversely to the moving direction of the stacking device. Thus, at least in one position, the connecting device is preferably arranged transversely or substantially transversely to the moving direction of the stacking device, respectively.

[0025] Alternatively, when the connecting device is arranged longitudinally to the direction of movement, the rotary feedthrough can be omitted in an advantageous development. Depending on the design, this requires an increased stroke of the device compared to a transverse orientation.

[0026] Preferably, the air outlet and the air supply opening of the air guiding element are arranged substantially equally spaced apart when the stacking device is in the closed position and in the open position.

[0027] Particularly preferably, the connection device is in a substantially maximum extension when the stacking device is in the closed position and / or in the open position. In an advantageous refinement, the connection device is in a substantially minimum extension when the stacking device is between the closed position and the open position, in particular in an intermediate position. It is particularly provided, for example, when using a telescopic tube as the connection device, that the tube is in an intermediate position for retraction and is extended or telescoped to the end points or the open and closed position, respectively. This minimizes the telescopic distance and thus reduces wear.

[0028] Preferably, the telescopic connection device comprises at least one tube-in-tube system.For example, the tube-in-tube system can be configured with, for example, 120 mm tubes or the like.

[0029] Preferably, the tubes of the tube-in-tube system are not (absolutely) fluid-tightly connected to one another. In particular, intentional leaks or no seals can be provided, respectively, so that any dust or particles present can escape by way of air leaks. At the same time, the air flow generated by the leaks forms an air cushion that reduces wear.

[0030] In an advantageous embodiment, the telescopic connection has at least one bellows. In addition to the tube-in-tube system, or also exclusively, a telescopic connection can be provided, provided that the bellows are constructed with sufficient rigidity so that they do not sag or sag significantly. The bellows can also be provided as protection.

[0031] Preferably, the telescopic connection comprises at least one hinged support device. Thus, for example, a V-shaped support can also be provided as a support for the hose. Such a V-shaped design is preferably located in a plane parallel to the stacking device and diverges towards the end positions in order to thus provide a telescopic connection.

[0032] In an advantageous refinement, at least one blowing device is connected to at least one air inlet of the air guide element. Preferably, a sufficient air flow can be provided by means of the blowing device for generating an air cushion effect.

[0033] According to the present invention, the stacking device for stacking goods, especially stacking bags (especially bags filled with goods) includes at least one conveying device, which has at least one conveying element for conveying goods, and at least one stacking platform, as described above.

[0034] The palletizing device according to the invention also has the advantages of the above-mentioned palletizing station according to the invention.

[0035] Preferably, the stacking device of the stacking station is at least partially displaceable between an upper track and a lower track of at least one conveying element of the conveying device. Since the stacking device can be displaced between the upper track and the lower track, a particularly flat structural design can be achieved.

[0036] In an advantageous refinement, the connecting device is arranged at least partially between the upper and lower rails in a plane parallel to the upper and / or lower rails. Since the connecting device is also arranged between the upper and lower rails of the conveying element, a particularly flat design can be facilitated without causing collisions of components with the conveying element.

[0037] In an advantageous refinement, the air guide element is or can be arranged at least partially between the upper rail and / or the lower rail in a plane parallel to the upper rail and / or the lower rail. The above-mentioned advantages also apply here, namely that a particularly flat structural design can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] Figure 1 1 shows a purely schematic top perspective view of an exemplary embodiment of a palletizing device 100 according to the invention, which has a stacking platform 1 according to the invention. The palletizing device 100 shown here is configured to arrange bags 201 filled with goods on a pallet in a predetermined layer arrangement or to palletize the bags. For this purpose, the palletizing device 100 comprises a bag feed 105, which receives bags filled by a packaging device 400, the details of which are not shown.

[0089] A shaping device 106 is arranged downstream of the bag infeed 105, which adjusts the height of the filled bags 201 or the height of the goods 300 to be packaged, so that the bags 201 exhibit particularly good stacking performance.

[0090] In the exemplary embodiment shown, three clamping-type rotating devices 107 are arranged downstream of the shaping device 106, which are respectively oriented toward the bags 201 to be stacked or the pieces 300 to be stacked, so that a specific stacking layer arrangement of the bags 201 with corresponding orientation can be produced on the stacking platform 1 or the intermediate stacking surface.

[0091] The conveying device 101 has a conveying element 102, which at this end is close to the stacking platform 1 for conveying bags 201 or items 300. The bags 201 can then be pushed or conveyed to the stacking platform 1 respectively by the conveying element.

[0092] Figure 2 1 shows two views of an area of ​​a palletizing device 100 according to the invention with a stacking platform 1 according to the invention, wherein the stacking platform or the stacking device 2 is shown in an open position 6 in the left-hand view and the closed position 5 of the stacking device 2 is shown purely schematically in the right-hand view.

[0093] Next to the palletizing device 100, a pallet with bags 201 stacked thereon or a pallet with stacked items can be seen, wherein it can be seen that in the exemplary embodiment shown here the uppermost bag layer 200 has a layer arrangement in which two bags are arranged longitudinally and three bags are arranged transversely. The bag layers 200 below are therefore arranged in the opposite orientation in order to provide a particularly stable bag stack.

[0094] During palletizing of bags 201, a bag layer 200 is first formed on the stacking table 1 or the stacking device 2, respectively. When the bag layer 200 is formed, the stacking device 2 is displaced into a closed position 5, in which the stacking device 2 is located above the pallet, and the bags 201 are subsequently pushed onto the pallet.

[0095] If the layer of bags 200 is in the correct position, the stacking device 2 is pulled open, wherein the layer of bags 200 is respectively pushed onto the pallet located therebelow or onto the layer of bags 200 already arranged on the pallet.

[0096] Figure 3 1 shows a stacking station 1 according to the invention in a purely schematic perspective view. It can be seen here that the stacking station 1 has a stacking device 2 with a stacking surface 8 on which bags 201 can be arranged to form a bag layer 200.

[0097] Therefore, the stacking device 2 is constructed in a hollow manner so that air can flow at least partially through it, so that the air can be blown out through the exhaust openings 11 in the upper side 7 or the stacking surface 8 of the stacking device 2, respectively, so that a kind of air cushion is formed under the bag layer 200, which facilitates pushing the bags onto the pallet under the stacking platform 1 or under the stacking device 2, respectively.

[0098] For supplying air to the stacking device 2 or the air outlet 11 respectively, the stacking station 1 according to the invention comprises an air supply device 4. In the exemplary embodiment shown here, the air supply device 4 has an air guide element 12 which comprises an air inlet 17 which is connected to a blowing device 16 here.

[0099] The air flow provided by the blowing device 16 is sent to the air inlet 17 of the air guide element 12 through the pipe, and the air flow is further sent to the air outlet 13 through the air guide element 12, and the air outlet 13 is connected to the connecting device 14. Here, the connecting device 14 is provided by a plurality of tubes 20, which are connected to each other in a telescopic manner. The length of the connecting device 14 can be changed or telescopic by means of such a tube-in-tube system 19.

[0100] One side of the connection device 14 is rotatably connected to the air outlet 13 of the air guide element 12 via a pneumatic rotary feedthrough 15. On the other side, a rotatable connection (which can also be formed as a pneumatic rotary feedthrough 15) is also formed, which is connected to the air supply opening 10 of the lower side 9 of the stacking device 2.

[0101] Figure 4 It is shown in Figure 3 1 , wherein the stacking surface 8 is not shown here, so that the interior of the stacking device 2 and the air supply opening 10 of the stacking device 2 are visible.

[0102] Figure 51 shows a side sectional view of a stacking station according to the invention according to the above-described figures. In the exemplary embodiment shown here, the stacking device 2 is in the open position 6, wherein the stacking device 2 is at least partially located between the upper rail 103 and the lower rail 104 of the conveyor element 102 of the conveyor device 101 of the palletizing device 100.

[0103] This is a significant advantage of the invention, since the special design of the air supply device 4 allows a particularly flat structure to be achieved, so that the stacking device 2 can be displaced without any risk of collision with the conveyor elements 102 of the conveyor device 101 .

[0104] This is, for example, due to the fact that the connecting device 14 is arranged as flat as possible below the stacking device 2 in a plane parallel to the stacking device 2. Since the connecting device is fixed or arranged independently of the position of the stacking device 2 in this plane, this means that it can be installed in the smallest possible assembly space. In particular, the stacking device 2 can also be moved between the upper rail 103 and the lower rail 104 together with the connecting device 14.

[0105] Figure 6 and Figure 7 Exemplary embodiments of stacking stations according to the invention are shown in , one in the open position 6 and one in the intermediate position 21 . Figure 3 The fully closed position 5 of this exemplary embodiment has been shown in FIG.

[0106] Figures 8 to 10 Schematically, an exemplary embodiment of a stacking station 1 according to the invention without a stacking device 2 is shown. It can be seen that the displacement or movement of the stacking device 2 is respectively achieved by a displacement device 3, which is provided by a rail system 22 here.

[0107] therefore, Figure 8 The fully closed position is shown in 5. Fig. 9 The middle position 21 is shown in FIG. Fig.10 The fully open position 6 is shown.

[0108] It can be seen in these figures that the air supply device 4 can be connected to the stacking device 2 via a telescopic connection device 14. Thus, there is a rigid or fixed air guide element 12 here, to which the connection device 14 is connected.

[0109] Thus, when the stacking device 2 is in the intermediate position 21, a tube-in-tube system 19 with minimal extension or telescoping is provided. Thus, the connection device 14 or the tube-in-tube system 19 can be extended to both ends, namely the open position 6 and the closed position 5. Thus, the connection device 14 in the intermediate position 21 is approximately transverse to the displacement direction 18.

[0110] By providing the tube-in-tube system 19 with a connection in a substantially rigid manner, a particularly smooth connection of the air supply device 4 to the stacking device 2 can be achieved. This also allows the stacking device 2 to be moved between the upper rail 103 and the lower rail 104 of the conveyor element 102 or conveyor device 101, respectively, without having to fear a collision, which would otherwise occur or could occur when using air hoses in so-called swing sets (bird cages).

[0111] Figures 11 to 13 , the stacking device 2 is shown again in a bottom view of the open position 6, the intermediate position 21 and the closed position 5. The different deflections of the telescopic connection 14 can also be seen here.

[0112] Depending on the design, in the exemplary embodiment shown here, a pipe-in-pipe system 19 comprising at least two pipes 20 can be used as the connecting line 14. This system does not require and is not expected to have special seals. For example, it can be ensured by means of specific leaks that dust entering the connecting device 14 is blown out again. In addition, an absolutely sealed system is not required, because no particularly high pressure is required to form an air cushion under the bag layer 200. In particular, in the process, the air flow between these pipe parts forms an air cushion that reduces wear.

[0113] Depending on the design, different types of connection devices 14 can also be provided. For example, in addition to the tube-in-tube system 19, a corrugated tube or a hose can also be used, which is for example fixed in a V-shaped support structure, which is movable in a corresponding plane.
