Description

[0001] Packing plant and method for operating

[0002] Description

[0003] The present invention relates to a packing system comprising at least one packing machine rotating through 360° and having at least two filling nozzles (distributed over the circumference) for filling bags, at least one bag attachment device having at least one discharge channel for attaching empty bags to the filling nozzles of the packing machine, and at least one discharge device for transporting filled bags with at least one conveyor device. The present invention further relates to a method for operating such a packing system.

[0004] Various designs of packing machines or packing systems comprising at least one packing machine have become known in the prior art. In particular, rotating packing machines with multiple filling nozzles distributed around the circumference are often associated with a so-called bag-opening plug, which accelerates empty bags in a so-called firing channel and shoots the empty bags onto a rotating filling nozzle. Such systems are also used, in particular, with so-called valve bags.

[0005] A bag is then shot onto a rotating filling nozzle and filled during the rotation. The filled bag is then discharged onto a discharge belt and fed, for example, to a palletizer. Such a packing system with a packing machine, a

[0006] Sackauf Stecker and a discharge belt is among others in the EP

[0007] 2 340 206 Al disclosed .

[0008] A disadvantage of such systems, however, is that, due to their design, there is a relatively large dead angle of at least 30°. This results from the fact that the bag opening plug or the discharge channel and the discharge belt are arranged radially from the central axis of rotation, and the two assemblies cannot be placed closer together due to space constraints, as otherwise the housing parts of the two assemblies would collide or interfere with each other.

[0009] Due to the resulting dead angle, part of the circumference is lost for the filling process. Depending on the rotation speed of the packaging machine, this reduces performance and / or filling accuracy. Furthermore, a relatively large installation space is generally required.

[0010] It is therefore the object of the present invention to provide a packing system which at least partially improves at least one of the aforementioned disadvantages.

[0011] This object is achieved by a packing system having the features of claim 1 and by a method for operating a packing system having the features of claim 11. Preferred developments of the invention are the subject of the subclaims. Further advantages and features of the present invention will become apparent from the general description and the description of the exemplary embodiment.

[0012] The packing system according to the invention comprises at least one packing machine rotating through at least 360° and having at least two filling nozzles, in particular distributed (evenly) over the circumference, for filling valve bags. The packing system further comprises at least one bag placing device with at least one discharge channel for placing empty valve bags onto the filling nozzles of the packing machine and at least one discharge device for transporting filled valve bags away with at least one conveyor device. The discharge channel of the bag placing device is arranged at a rotation angle of the packing machine of 0°, and at least one transfer area of ​​the discharge device for a filled bag is arranged at a rotation angle of the packing machine between 340° and 360°.

[0013] The packing system according to the invention is used for filling valve bags. In the application, the term "bag" is used synonymously with "valve bag" in some places.

[0014] The fact that the firing channel is arranged at a rotation angle of the packing machine of 0° means, in particular, that a longitudinal axis of the firing channel is arranged radially to a radial axis of the packing machine, with the installation location of the bag insertion device being defined at a rotation angle of 0°. At this point or at this rotation angle of the packing machine, empty bags are applied or shot onto a rotating filling nozzle using the bag insertion device.

[0015] The fact that at least the transfer area of ​​the discharge device is arranged at a rotation angle of the packaging machine between 340° and 360° means, in particular, that at least one central area or at least one central longitudinal axis of the discharge device, and in particular of the transfer area of ​​the discharge device, is arranged or positioned radially to the central axis of rotation of the packaging machine between 340° and 360°. The 340 to 360° are counted starting from the rotation angle of 0° of the packaging machine, i.e., starting from the location of the bag applicator. It should be noted that 360° corresponds to a complete rotation, whereby 360° and 0° correspond to the same rotation angle of the packaging machine.

[0016] The positioning points of the bag insertion device and discharge device selected according to the invention ensure, in particular, that the angular difference between the central longitudinal axes of the discharge channel and the transfer area of ​​the discharge device is less than or equal to 20°, preferably less than or equal to 10°, and particularly preferably less than or equal to 5°, and in particular 0°. This makes it possible to provide a particularly compact packing system.

[0017] The bag insertion device is used, in particular, to accelerate a bag inserted into the launching channel of the bag insertion device, so that it is launched onto a filling spout. For this purpose, the bag insertion device is preferably positioned approximately one bag width away from the rotating filling spouts, with a certain additional distance of, for example, a few millimeters being provided, in order to preferably bridge the shortest possible distance to the filling spout, while at least ensuring that the bag completely emerges from the launching channel.

[0018] The discharge device comprises in particular at least one conveyor belt, at least one bag cleaning device, at least one control weighing device and / or at least one discharge device and / or any combination thereof.

[0019] In particular, at least the bag attachment device and / or the discharge device are designed to be as small as possible. This means in particular that the most compact housing possible is provided around the individual components so that these can be arranged as close to one another and / or one above the other or next to one another as possible. The discharge device or the conveyor device of the discharge device or the transfer area of ​​the discharge device is in particular arranged such that a filling nozzle with a filled bag held thereon can rotate at least partially above it or can travel over it, so that a filled bag can, for example, be simply tipped downwards or slightly forwards and then hits the transfer area of ​​the discharge device and can be transported further.If, for example, a bag is not completely filled and / or vented and needs to undergo another rotation, the discharge device can also be run over with the attached bag.

[0020] The packaging machine preferably comprises at least two filling nozzles, which are preferably evenly distributed around the circumference of the packaging machine. In particular, 6, 8, 12, 16 or even 20 nozzles are customary or expedient. Depending on the design, however, fewer or more nozzles and even odd numbers can be provided. The circumference is selected in particular such that all filling nozzles or all filling modules, each with one filling nozzle, can be arranged distributed around the circumference. In general, a particularly compact design is preferred, which here means the individual filling modules being arranged as closely as possible in order to keep the circumference and thus the diameter of the packaging machine as small as possible.

[0021] The packaging system according to the invention offers many advantages. Because the discharge device is positioned at a very late rotation angle and, in particular, can be aligned with the discharge channel, a significantly smaller dead angle of the packaging machine is achieved.

[0022] A dead angle is the angular range of the rotation of the packing machine in which a bag is not attached to the filling nozzle and therefore cannot be filled and / or vented and / or processed in any other way.

[0023] Reducing the dead angle offers significant advantages. On the one hand, allowing the bag to remain at the filler spout for a longer period of time can result in more precise filling, but alternatively, it can also result in higher system performance and / or better venting. Higher system performance can be achieved, for example, by increasing the speed of the packing machine while maintaining the same dwell time for a bag to be filled at the filler spout compared to the state of the art due to the longer travel distance along the circumference. Filling accuracy and the venting rate increase at a constant speed because the dwell time at the filler spout is longer compared to the state of the art.

[0024] The aforementioned advantages result from the fact that in the prior art the discharge device is generally arranged at a rotation angle of the packing machine of 330° at the latest, and thus an angle of at least 30° remains between the bag insertion device and the discharge device.

[0025] By increasing the angle of rotation of the discharge device's installation location by at least 10° according to the invention and thus extending the dwell time of the bag on the filling nozzle, the performance can be increased in particular between approximately 2.8% and 8.3%, or, depending on the design, the venting time or the filling accuracy can be increased.

[0026] A further advantage of an inventive arrangement of the discharge device at a 360° rotation angle or 0° rotation angle or in alignment with the bag applicator or with the ejection channel of the bag applicator is that a symmetrical design of the peripheral components can be achieved. This means that it is no longer necessary to align individual components to left-turning or right-turning packing machines, depending on which direction of rotation is dictated by the installation location in systems according to the state of the art. Because the bag applicator and the discharge device can be arranged in alignment, at least in the area close to the packing machine, universally applicable and installable packing systems can be planned. This allows for much greater flexibility in planning and installation.

[0027] In general, the installation location of the discharge device with a rotation angle of 340° to 360° can enable a significantly smaller installation space for the packing system, whereby this particularly refers to the installation space in terms of width.

[0028] Preferably, the discharge device is arranged at least partially below the bag-loading device. Such a configuration is provided in particular when the discharge device is set at a rotation angle of the packaging machine of 0°. However, the discharge device can also be arranged at least partially below the bag-loading device in other rotation angle ranges.

[0029] Particularly preferably, the discharge device is arranged at least partially below the discharge channel. In particular, at least the transfer area is arranged below the discharge channel.

[0030] In expedient embodiments, the bag-loading device and the discharge device are provided as a single assembly, at least in sections. Such a configuration is particularly useful when, for example, the transfer area or the transfer area of ​​the bag to the discharge device is provided below the discharge channel. The bag-loading device and the discharge device can then be installed as a single assembly, at least in sections.

[0031] In expedient further developments, at least one transfer device is provided, which is suitable and designed to feed filled bags from a filling nozzle of the discharge device or to transfer them to the discharge device, in particular to the transfer area of ​​the discharge device. Because a bag is transferred to the discharge device during rotation, at least one baffle plate or the like can be assigned, in particular at least in the transfer area of ​​the discharge device, so that the bag does not slip beyond the discharge device, roll over, and / or otherwise be removed from the discharge process.

[0032] The transfer device can be designed in various ways and is, in particular, assigned to the packing machine, assigned to the discharge device, and / or provided as a separate assembly. Depending on the design, the transfer device can also be provided, for example, by a retractable or retractable filling nozzle, so that a filled bag can simply fall out by retracting the filling nozzle and thus pulling it out of the bag, e.g., downwards.

[0033] The transfer device is preferably assigned to the packaging machine and in particular comprises at least one ejection device. Such a ejection device can, for example, be provided below the filling spout and push a sack forwards when a fill weight is reached. Depending on the design, a parallelogram ejection device or the like can also be provided. In expedient designs, the transfer device comprises at least one buffer device. Such a buffer device is provided in particular to remove a sack from the filling spout at a predetermined time without transferring it directly to the discharge device. This can be particularly expedient if the discharge device and the sack attachment device are aligned or very close to one another, so that a sack cannot be transferred to the transfer area quickly enough without the sack to be removed or...A full bag to be transferred would obstruct a newly loaded empty bag. Such a buffer device can be designed, for example, as a sheet or tray onto which a filled bag is briefly transferred before the bag is then transferred to the discharge device.

[0034] Preferably, the packaging machine can be operated in a left-handed and right-handed rotation. Such a configuration is particularly possible if the discharge device and the discharge channel or the attachment device are both provided at a rotation angle of 0° or 360° or are aligned. Then, the direction of rotation of the packaging machine is irrelevant, and the packaging machine can be operated in a left-handed or right-handed rotation.

[0035] Particularly preferably, the bag placing device is assigned at least one conveyor device with at least one conveyor section with at least one first end and at least one second end, wherein by means of the conveyor device empty bags are conveyed along the conveyor section from the first end at least in sections and preferably individually to the second end and are fed there, in particular individually, to the bag placing device. The bags can in particular be conveyed through the conveyor section in a hanging manner, at least in sections. Preferably, at least one supply of bags is included, which supply, in particular in the embodiment with a conveyor device, is arranged at the end of the conveyor section which is opposite the end of the conveyor section with the bag placing device (the second end), i.e. at the first end.

[0036] Particularly when a conveyor system is included or when a conveyor line spatially separates the bag supply from the bag insertion device, particularly close rotation angles of the bag insertion device and discharge device, or an aligned design, can be achieved, since the technology otherwise required for insertion into the discharge channel, such as grippers and other components, no longer need to be located in the area of ​​the bag insertion device. This frees up installation space below the discharge channel or the bag insertion device, allowing the discharge device to be installed there.

[0037] In particular, a conveyor device or a conveyor line or a bag placement system according to the application with a conveyor line can be provided with all the features individually and / or in combination, as described in the embodiment and as shown in the figures.

[0038] Furthermore, reference is made to German patent application 10 2023 113 439.6, the content of which is incorporated by reference. In particular, a bag attachment system can be used in the packing system according to the application, as described in German patent application 10 2023 113 439.6. Features from the referenced application can further develop the packing system according to the application, individually and / or in combination. The method according to the invention is suitable for operating a packing system as described above. An empty bag is shot onto a filling spout at a rotation angle of the packing machine of 0°, and the filled bag is transferred to the discharge device at a rotation angle of 340 to 360°.

[0039] The fact that the bag is transferred to the discharge device at a rotation angle of 340° to 360° means that the discharge device or the transfer area of ​​the discharge device is located within this angular range radially from the rotation axis of the packing machine. Depending on the design, it may also be possible for the bag to be released a certain angular range earlier, since the bag experiences a certain lateral acceleration during transfer due to the rotation of the packing machine, depending on the design. So, depending on the technology and design used, a bag dropped at 340° does not necessarily have to land on the discharge device at 340°.

[0040] Typically, the 360° rotatable packing machine is designed to fill a bag in one rotation. Depending on the design, however, errors or incidents may occur, resulting in a bag not being completely or sufficiently filled upon first passing through the discharge device. Depending on the design, a bag may then be discarded and / or remain at a filling spout for one or more additional rotations, so that, for example, the bag is only filled or ejected after 720°. Normally, however, filling should preferably be completed after one rotation.

[0041] Preferably, the bag is filled during a significant portion of the rotation. The filling process includes both the filling of the product and a venting period, which is determined depending on the product and the type of filling. Depending on the design, the filling and venting times may overlap.

[0042] In particular, it is preferred that the bag remains at the filling nozzle during a substantial part of a (complete) rotation of the packing machine.

[0043] Particularly preferably, the filling spout is released before the bag re-enters the bag insertion device. This allows the bag to be removed from the filling spout, especially shortly before reaching the discharge device. As previously described, the time at which a bag needs to be removed from the filling spout depends on the drop time or transfer time and the peripheral speed of the packing machine.

[0044] Further advantages and features of the present invention will become apparent from the embodiment which will be explained below with reference to the accompanying figures.

[0059] Figure 1 shows a purely schematic perspective view of a bag application system 100 according to the application or a packing system 50 according to the application.

[0060] In the exemplary embodiment shown here, the packing system 50 comprises a rotating packing machine 500, by means of which, in the exemplary embodiment shown here, bulk material can be filled into bags. In the exemplary embodiment shown here, the packing machine 500 comprises eight filling modules 502 distributed over the circumference, each comprising a filling nozzle 501. The filling nozzles 501 are arranged outwards and distributed over the circumference of the packing machine 500. The filling nozzles 501 can thus rotate 360° about a central rotation axis 503, with an empty bag being pushed or shot onto a filling nozzle 501 at a specific position and then filled during the rotation. For this purpose, the product to be filled is fed via the filling nozzle 501 from a silo (not shown in detail here). For this purpose, the corresponding conveyor technology can be provided in particular in the filling modules 502.

[0061] For attaching or, in this case, shooting empty bags 400 onto a filling nozzle 501, a bag attachment device 200 is provided in the illustrated embodiment, which in this case comprises a firing channel 201. The bag attachment device 200 shown is designed such that a bag 400 received in the firing channel 201 is accelerated by means of a driven conveyor belt and a roller bar and is shot towards a filling nozzle 501 on the side of the firing channel 501 facing the packaging machine 500. The shooting of the empty bags is adapted to the rotation speed of the packaging machine 500 and thus to the filling nozzles 501 rotating past.

[0062] In the prior art, such a bag applicator 200 typically includes a bag supply and gripper technology, as well as other components for separating bags from a stack of bags, lifting them, and feeding them to the loading channel 501. However, depending on the design and location of such a packing system, such a bag applicator, or such a bag applicator 200, this can be disadvantageous. On the one hand, such bag applicators known from the prior art require considerably more space than the embodiment shown here.Furthermore, the bag supply and the necessary technology consisting of a large number of moving parts for separating bags and inserting the separated bags into the discharge channel are located in the dirty area of ​​the packing machine, which is always accompanied by a not inconsiderable dust load, especially when filling bulk material into bags, for example cement, even when optimal filling conditions and optimal technology are present.

[0063] Furthermore, the bag supply is then in an unguarded and accessible area, which can also lead to problems depending on the location of the bag loading device or the packing machine.

[0064] To the bag supply 300 or the supply 300 for empty bags 400 and the technology for separating bags and incoming

[0065] To separate the bag from the shot channel, a conveyor device 1 is provided in the illustrated embodiment, which comprises a conveyor section 2. The conveyor device 1 and the bag placement device 200 are comprised here by a bag placement system 100 according to the application.

[0066] The conveyor device 1 or the conveyor line 2 has a first end 3 and a second end 4. The second end 4 of the conveyor line 2 is assigned to the bag insertion device 200, wherein empty bags are introduced individually at the first end 3 of the conveyor line 2.

[0067] In order to convey the bags 400 along the conveyor line 2, at least one conveyor element 5 is provided, which conveys the empty bags 400 in the embodiment shown here in a hanging manner in the direction of the bag attachment device 2.

[0068] The bag insertion system 100 according to the application and the resulting separation of the bag insertion device 200 and the bag supply 300, or the technology required for introducing the empty, individual bags into the conveyor line 2, make it possible to relocate the supply 300 from this feed device 600 to a clean and enclosed area. This prevents unauthorized persons from stealing empty bags 400 from the supply 300 of the bag insertion system 100. Furthermore, the supply 300 and the bag feed device 600 can be located in a relatively clean area, which generally results in a longer service life and requires less frequent maintenance.

[0069] In the illustrated embodiment, the conveyor line 2 is depicted as relatively short and linear. However, this only serves to better illustrate the bag-loading system 100 according to the application.

[0070] However, the conveyor line 2 can preferably be designed to be of any desired length and, depending on the design, can also have left and right curved sections 7 and / or convex or concave curved sections 8, which are not shown in Figure 1, however. This makes it possible to arrange the conveyor line 2 around curves and even with a height difference. In particular, it is also possible for the bag supply 300 and the bag placement device 200 to be arranged on different floors of a building or hall.

[0071] Figure 2 shows a purely schematic plan view of the embodiment already shown in Figure 1. Here, too, one can see the supply 300 for empty bags 400, the conveyor device 1 with the conveyor line 2, and the bag-loading device 200 with the firing channel 201 for firing empty bags 400 onto the rotating filling nozzles 501 of a rotating packing machine 500.

[0072] Figure 3 shows a purely schematic representation of a packing system 50 known from the prior art, comprising a rotating packing machine 500, a bag-applying device 200 and a discharge device 700.

[0073] Here, the bag-loading device 200 comprises, as is customary in the prior art, a bag-feeding device 600, by means of which bags are separated and transferred into the loading channel, and a supply 300 for empty bags 400. However, these can also be fed externally continuously as bundles or from a roll, or automatically.

[0074] The discharge device 700 serves to transport filled bags 400 at a filling nozzle 501 during the rotation of the packing machine 500, for example to convey them to a palletizer.

[0075] The discharge device 700 is not depicted in the previously shown embodiment. However, it can be seen here that, due to the necessary technology of the bag-loading device 200 and in particular due to the assemblies that separate the empty bags 400 and feed them to the discharge channel 501, the discharge device 700 must be arranged offset by at least approximately 30° from the bag-loading device 200, as in the prior art shown.

[0076] In this case, the firing channel 201 is generally provided radially to the rotation axis 503, wherein according to the application the firing channel 201 is arranged for or the central longitudinal axis of the firing channel 201 at a rotation angle of the packaging machine 500 of 0° or the installation location of the firing channel 201 is defined as a 0° rotation angle of the packaging machine 500.

[0077] In the exemplary embodiment shown, the packing machine rotates anti-clockwise, whereby the discharge device 700 in the prior art must be arranged at a rotation angle of approximately 330° at the latest, since otherwise, due to the design, there is not enough space available to position the bag loading device 200 and the discharge device 700 next to one another. This leaves at least an angle c between the ejection channel 201 and the discharge device 700 of approximately 30°, resulting in a relatively large so-called dead angle in which the bag can no longer be filled because it must already have been ejected. This means that the system either has to run more slowly in order to completely fill the bag by the 330° rotation and still achieve the most accurate filling possible, or optionally the output can be increased if the filling is less accurate.

[0078] Figure 4 again shows the embodiment according to Figures 1 and 2 in a plan view, wherein the housing 19 of the bag attachment device 200 is not shown here in order to illustrate how slim the bag attachment device 200 is or can be in principle designed without the otherwise required bag holder from the bundle.

[0079] According to the application, this results in a separation of the supply 300 from bags 400, depending on the design with the bag feeding device 600, and the bag attachment device 200 being possible.

[0080] This is achieved by providing a conveyor line 2 or a conveyor device 1 between these components. This makes it possible, as previously described, to safely accommodate the bags and the technology required for their introduction into the conveyor line 2 and, depending on the design, also in a clean area. Furthermore, this allows the discharge device 700 to be arranged at a larger rotation angle, as described in more detail in the following figures.

[0081] Figure 5 shows a purely schematic illustration of a further embodiment of a packing system 50 according to the application or of a bag-loading system 100 according to the application. Here, too, a rotating packing machine 500 is provided, which can rotate 360° around a rotation axis 503.

[0082] Here too, filling nozzles 501 are arranged distributed over the circumference, whereby here too eight filling modules 502, each with a filling nozzle 501, are provided.

[0083] As soon as the bags reach a predetermined fill weight, they are removed from the filling nozzle 501 by a transfer device 800 (not shown in detail) and fed to the transfer area 702 of a discharge device 700. The transfer device 800 is assigned to the packing machine 500 and is designed as a so-called discharge device 801. Depending on the configuration, the transfer device 800 can also include a buffer device 802 (not shown in detail), which temporarily stores a filled bag 400 so that the corresponding filling nozzle 501 is actually freely accessible upon reaching the discharge channel 201.

[0084] In the embodiment shown, empty bags 400 are fed to the bag applicator 200 via a conveyor line 2 of a conveyor device 1. This allows the bag applicator 200 to be designed very slim, so that in the embodiment shown here, the

[0085] The firing channel 201 is provided at a rotation angle a of 0°, wherein the discharge device 700 or the conveying device 701 of the discharge device 700 or the transfer area 702 is also provided at a rotation angle b of 360° or 0°.

[0086] Thus, in the embodiment shown here, the discharge channel 201 of the bag applicator 200 and the discharge device 7 or the conveyor device 701 or the

[0087] Transfer area 702, to which a filled bag 400 is transferred, can be arranged in a line. In the exemplary embodiment shown, this is achieved in that the bag placement device 200 and the discharge device 700 or the conveyor device 701 or the transfer area 702 are provided at a height offset at a rotation angle a, b of 0° and 360°, respectively. The discharge device 700 is arranged below the bag placement device 200 or below the discharge channel 201. This enables a particularly slim design of the packing system 50, wherein the bag supply 300 and the bag feed device 600 are arranged spatially separated from the bag placement device 200 via the conveyor line 2 or the conveyor device 1. Furthermore, when setting up the discharge device 700, it is not necessary to consider whether a right-handed or left-handed rotating packing machine is installed.The slimmer design also allows for easier project planning in confined spaces.

[0088] Figures 6 and 7 show two further embodiments of packing systems 50 according to the application with bag insertion systems 100 according to the application.

[0089] In the exemplary embodiment shown in Figure 6, a left-rotating packing system 50 is shown, with the bag applicator 200 or the discharge channel 201 being arranged at a rotation angle a of 0°. The conveyor device 701 of the discharge device 700 or the transfer area 702 is provided at a rotation angle b of approximately 350° in the exemplary embodiment shown here. Thus, an angle c of only approximately 10° exists between the central longitudinal axis of the discharge channel 201 and the central longitudinal axis of the discharge device 701, which also represents a significant reduction in the system's size compared to the prior art.

[0090] In Figure 7, both the transfer area 702 and the

[0091] Conveying device 701 or the discharge device 700 and the bag attachment device 200 or the discharge channel 200 are provided at a rotation angle a, b of 0° or 360°.

[0092] In contrast to the previously shown embodiment, however, here the discharge device 700 extends laterally below the discharge channel 201 at an angle c of 10°. This configuration also offers significant space savings, which is achieved here by the fact that the discharge device 700 can be arranged, at least in sections, below the bag insertion device 200 or the discharge channel 201. This is also achieved by the fact that the bag supply 300 and the bag feed device 600 are spatially separated from the bag insertion device 200 via the conveyor device 1 or the conveyor line 2.

[0093] Figure 8 shows a purely schematic perspective view of an embodiment of a bag-loading system 100 according to the application. Here, too, the supply 300 for empty bags 400 can be seen, which are introduced into a conveyor section 2 of the conveyor system 1 via a bag feed device 600. In the embodiment shown, it is purely schematically indicated that the conveyor section 2 can be curved and can also overcome height differences. For example, a right-hand curve 7 is provided here, with convex and concave curves 8 being indicated purely schematically by the dotted line.

[0094] In the exemplary embodiment shown, two circulating conveyor elements 5 run along the conveyor line 2, which here are designed as belts 6 or are provided here by round belts. Depending on the exemplary embodiment, other conveyor elements such as belts and / or chains and / or the like can also be used. In the exemplary embodiment shown here, the bags 400 are clamped between the two conveyor elements 5 during transport along the conveyor line 2 and are conveyed by a similarly directed movement of the belts or conveyor elements 5 from the first end 3 to the second end 4 into the bag applicator 200.

[0095] The basic structure of the conveyor line 200 is defined here by a support structure 9, wherein the support structure 9 comprises a support element 10, which is provided here by a correspondingly shaped tube 20. Arranged at specific intervals on this tube 20 are holding elements 11, on which bearing devices 12 for the conveyor elements 5 are provided.

[0096] Figure 9 shows a purely schematic representation of a section of a conveyor line 2 of a conveyor device 1 according to the application. The support structure 9 is known here, which comprises a support element 10, which is provided here by a pipe 20.

[0097] Attached to this support element 10 are holding elements 11, on which rollers 21 are provided as bearing devices 12. In the illustrated embodiment, a conveyor element 5 is guided forward on one side of a roller and returned on the other side of the roller 21. Thus, conveyor elements 5 circulating on the left and right are provided.

[0098] In the exemplary embodiment shown here, the storage devices 12 comprise a roller 21 as a running roller for each conveyor element 5 and, on the other side of the respective guide element 5, a guide element 25, which is designed here as a roller bearing 26. The counterpart to the roller 21 can also be another roller or a sheet metal or the like, which holds the conveyor element in the roller 21. In the exemplary embodiment shown here, the empty bags 400 are clamped centrally between the two conveyor elements 5 or the belts 6. To ensure that the clamped bags do not get caught on the storage devices 12 or when crossing the storage device 12 in the exemplary embodiment shown here, lifting devices 18 are provided here, which are provided here by appropriately shaped rods. The lifting devices are generally useful at every transition or on every holding element 11, but are not shown in more detail in the figures.

[0099] These bars 22 comprise a ramp-like structure 23 which slightly lifts the bags 400 hanging between the belts 6 so that they can slide over the storage devices 12.

[0100] A further advantage of the lifting device 18 is that the T-shaped leg of the empty bags, which are designed here as valve bags 400, is slightly lifted and pre-bent or pre-formed when crossing each holding element 11 or when crossing the storage device 12, so that the valve of the valve bag 400 can be opened more easily later.

[0101] Figure 10 shows a purely schematic representation of the second end 4 of a conveyor line 2 of a conveyor device 1 of a bag placing system 1 according to the application, at which point the empty bags 400 are transferred from the conveyor line 2 to the bag placing device 200.

[0102] It is shown that a guide device 13 is provided on the left and right, which here is designed as guide plates 24. These guide plates 24 run slightly upwards from the conveyor section 2 in order to convey the bag in the direction of the firing channel 201 of the bag attachment device 200. By means of the appropriately shaped guide devices 13 and the upward movement here, the T-shaped, flat upper leg of a bag 400, which is designed here as a valve bag 400, is opened while the bag body is simultaneously secured between the conveyor elements 5 and thus inserted into the diamond-shaped or rounded firing channel 201.

[0103] Figures 11, 12, 13, 14 and 15 show further perspective views of the second end 4 of the conveyor line 2 of the conveyor device 1 of a bag placing system 100 according to the application and here in particular the transition to the bag placing device 200.

[0104] Here, too, the deflection station 16, the drive station 14 and the discharge channel 201 of the bag loading device 200, which is connected to the conveyor line 2, can be clearly seen.

[0105] In Figure 11, it can be seen, among other things, at the front end of the firing channel 201 that a roller bar 202 is provided as a counterpart for a drive belt 203, which accelerates the bag 400 in the firing channel 201.

[0106] Figure 11 further shows that a deflection station 16 is provided at the second end 4, which deflects the conveyor element 5 or the belts 6 and guides them back to the first end 3, where a deflection station 16 is also provided in the embodiment shown here.

[0107] Furthermore, it is also shown here that the conveyor element 5 is deflected from the horizontal conveying direction of the conveyor line 2 such that it is fed to a drive station 14 arranged above. The left and right conveyor elements 5 can be driven by a common drive. Figure 11 also indicates that a tensioning station 17 can also be provided, by means of which a specific tension can be applied to the conveyor elements 5 initially and / or during subsequent tensioning.

[0108] Furthermore, Figures 11 to 14 show the guide devices 13, which are designed as guide plates 24. The guide devices 13 are not shown in Figure 15. Thus, the lifting devices 18 can be seen, onto which the bearing devices 12 are placed in the illustrated embodiment.
