[0003] Description

[0004] The present invention relates to a packaging system comprising at least one packaging machine, in particular for filling bulk goods into bags, and at least one discharge device for transporting filled bags. The packaging machine includes at least one filling module with at least one filling nozzle, wherein the filling module is suitable and configured to dispense a filled bag. The present invention further relates to a method for operating such a packaging system.

[0005] Packaging systems for filling bulk goods are known in various designs in the prior art. Among these are packaging systems that include a rotary packaging machine. Such a rotary packaging machine comprises several filling modules, usually evenly distributed around its circumference, each with a filling nozzle. Empty bags are attached to these filling nozzles and filled during rotation.

[0006] Depending on the design, each filling module includes a tilting sack chair, which is used to tip the filled sack onto a conveyor belt. However, the sack must first be sealed or have a self-sealing valve.

[0007] The filled bags, which are actively sealed depending on the design, are then simply tipped down, whereby the rotation and tipping generate a radial force and a force Haver & Boecker

[0008] This effect occurs in the direction of rotation. This results in the bag impacting, for example, on a conveyor belt, with a considerable and sometimes unfavorable force input, particularly due to the sudden and complete reduction of tangential forces. In addition to bag deformation, a "passive" bag closure (where the valve closes upon impact) often leads to dust being released, meaning that in the worst case, the impact can measurably alter the fill weight.

[0009] Similar problems also sometimes occur with non-rotating packaging machines when dropping the bags after filling, for example with inline packaging machines or single-stem systems.

[0010] It is therefore the object of the present invention to provide a packaging system in which the aforementioned disadvantages are at least partially improved.

[0011] This problem is solved by a packaging system with the features of claim 1, by a transfer device with the features of claim 17, and by a method for operating a packaging system with the features of claim 18. Preferred embodiments of the invention are the subject of the dependent claims. Further advantages and features of the present invention will become apparent from the general description and the description of the exemplary embodiment.

[0012] The present invention relates to a packaging system comprising at least one packaging machine, in particular for filling bulk goods into valve bags or preferably also other containers such as open-face bags, and at least one discharge device for transporting filled valve bags. The packaging machine comprises at least one filling module with at least one filling nozzle, wherein the filling module is suitable and configured to fill a Haver & Boecker

[0013] Valve bags are to be dispensed. At least one transfer device is arranged between the packaging machine and the conveying device. The transfer device includes at least one collection section, to which at least one deceleration device is assigned in order to enable the gentlest possible transfer of a filled valve bag from the packaging machine, upright, to the conveying device, or upright onto the transfer device and then onward.

[0014] That a filled valve bag is transferred upright to the conveying device means, in particular, that the bag is not tipped or thrown onto its side, but rather transferred upright so that the filled valve bag rests on its bottom. The bag is conveyed upright, at least during the transfer to the conveying device and at least temporarily during transport through the device. To prevent the transferred bag from falling over, a support is preferred, depending on the design. This support is intended to guide or support the bag laterally (especially on the left and right) so that it does not fall over during further transport. Therefore, it must also be supported on the left and right (guided) to prevent it from falling over. In particular, not only is the bag slowed down, but preferably also supported, so that a gentle landing can be achieved.

[0015] Preferably, the valve (which is preferably not yet or not completely closed) is located above the fill level at least until the transfer to the conveying device.

[0016] The packaging machine according to the invention is particularly suitable and designed for filling valve bags. Depending on the configuration, Haver & Boecker

[0017] The packaging machine according to the invention is particularly suitable and designed to fill open-face bags.

[0018] Preferably, the packaging system includes at least one bag-mounting device by means of which empty bags can be automatically shot or attached to an empty or free filling nozzle. Depending on the design, however, manual bag mounting is also preferred.

[0019] Preferably, the filled bags are transferred open and / or closed to the removal device using the transfer device.

[0020] The removal system includes, in particular, at least one conveying device such as a conveyor belt, rollers and / or the like, by means of which the filled bags can be transported further.

[0021] For example, each filling module can include a tipper trailer and / or the like for transferring a filled bag to the transfer device.

[0022] The packaging system according to the invention offers many advantages. A significant advantage is that the transfer device is suitable and designed to enable the gentlest possible transfer of a filled sack from the packaging machine to the discharge device.

[0023] This means, in particular, that the transfer should preferably be low-impact, with the least possible force acting on the filled bag. It is especially preferred that the bag be decelerated as slowly as possible or that there be no unbraked impact. This is intended to ensure, in particular, minimal deformation and a Haver & Boecker

[0024] Minimal dust generation during discharge or transfer is ensured. Depending on the design, this can also lead to improved weight accuracy, as uncontrolled dust emissions are prevented.

[0025] Furthermore, by means of a particularly gentle discharge or transfer of filled and still open bags by the transfer device, it can be achieved, depending on the design, preferably even unsealed open bags can be transferred to the transfer device, which are then subsequently closed in a known manner.

[0026] The delay device is preferably designed and configured to absorb at least one force away from the filling nozzle. In the case of a rotary packaging machine, the force away from the filling nozzle is, for example, a force in the radial direction, while in the case of inline packers, it is the force along the longitudinal extent of the filling nozzle in the direction of the delay device. In the case of inline or single packers, the force to be absorbed is also referred to as a radial force, analogous to rotary packaging machines.

[0027] Intercepting or decelerating a force can also, in particular, prevent a sack from accelerating, for example, on an inclined plane. Depending on the design, it may be preferable for the sack's velocity to remain constant, with the deceleration consisting of preventing an increase in velocity after or during the transfer.

[0028] In rotating packaging machines, it is also preferred that the force is first absorbed tangentially and then radially. The rotation of the packaging machine in the direction of rotation results in a tangential force, which, for example, when a bag is ejected, acts parallel to the radial force, whereby the tangential force is preferably balanced first. (Haver & Boecker)

[0029] The radial force is absorbed, and then a delay or absorption of the radial force occurs. With row packers, it is usually only necessary to absorb the radial force.

[0030] In advantageous embodiments, the delay device comprises at least one so-called inlet funnel, at least one braked roller conveyor, and / or at least one lateral guide, and / or functionally comparable devices or assemblies. A lateral guide can preferably comprise at least one rod (preferably on both sides of the bag), at least one sheet metal plate, at least one roller strip, and / or the like. The guide is intended to prevent the bag, which is standing upright on its base, from falling over. Preferably, when using an inlet funnel, the guide can be provided by the funnel itself, integrated into it, or additionally.

[0031] In advantageous embodiments, the inlet funnel comprises at least one pivotable flap. It is particularly preferred that the inlet funnel is formed, for example, by at least two (lateral) flaps or plates arranged in a funnel shape relative to each other in the conveying direction. The deceleration can then be achieved, for example, by pivoting the flaps, which are preferably pre-loaded to slow down the conveying of the bag.

[0032] Preferably, the deceleration device actively and / or passively decelerates the bag or its speed. The bag is preferably conveyed at a predetermined speed or decelerated to a specific speed. Passive configurations may preferably include a braked roller conveyor, an inlet hopper (e.g., with pressure cylinders), and / or the like. An active configuration may, in particular, include sensors, as Haver & Boecker

[0033] Then, components are actuated with the necessary force based on sensor readings to achieve a defined deceleration. A powered conveyor belt can also be used for active deceleration.

[0034] Preferably, the packaging machine is designed as a rotary packaging machine, which preferably comprises several filling modules distributed essentially evenly around its circumference. Each filling module preferably includes at least one filling nozzle in which a bag to be filled is filled during the rotation of the packaging machine, preferably within one revolution.

[0035] The filling module is particularly well-suited and designed to actively and / or passively deliver a filled bag to the transfer device. Passive delivery refers specifically to gravity transfer, where, for example, a bag lift is tilted, causing the filled bag to move or be "dropped" towards the transfer device solely by gravity. Active delivery can be achieved, for example, by means of a slide or similar device, actively conveying the bag towards the transfer device. Instead of a slide, and / or additionally, a conveyor belt or other conveying element can also be used to transport the filled bag towards the transfer device.

[0036] According to the invention, the transfer device comprises at least one collection section. Such a collection section can, in particular, comprise at least one sliding plate, at least one roller conveyor, at least one conveyor belt, at least one conveyor belt, or several preferably parallel conveyor belts. A particularly gentle transfer of the filled sack from the packaging machine to the Haver & Boecker can preferably be carried out via such a collection section.

[0037] Transfer facility or to / onto the removal facility.

[0038] Preferably, the collection section is arranged at least partially and / or at least temporarily inclined. Inclined in this context refers in particular to an arrangement directed downwards from the packaging machine, so that a kind of chute is provided or, more generally, a suitable force input is achieved.

[0039] Preferably, at least one conveying section is assigned to the receiving section. The conveying section can preferably be part of the transfer device and / or also be provided by the discharge device.

[0040] Depending on the design, the collection section of the transfer device can preferably be integrated into the packaging machine and, for example, be part of the bagging unit or replace it. Even with such a design, the

[0041] The collection section must be inclined, at least in sections and / or at least temporarily, to move the filled bag towards the conveyor line by gravity, for example, by means of a tilting roller conveyor. Depending on the design, the collection section can also be arranged essentially horizontally, in which case it preferably includes suitable conveying means for transporting the filled bags away from the filling nozzle towards the conveyor line.

[0042] Particularly preferably, at least one damping element is assigned to the collection section. Such a damping element is intended, in particular, to dampen, cushion, or attenuate the transfer energy or the movement of the bag during transfer from the filling module or the filling nozzle to the transfer device. Such a damping element can preferably be designed as a spring plate and / or the like, in particular according to Haver & Boecker.

[0043] At least one type of impact plate is preferred. In particular, such a damping element is provided outside the rotation of the packaging machine. In general, the damping can be achieved, in particular, by means of active and / or passive elements. Preferably, for example, springs, dampers, and / or pneumatic elements can be used. The damping element can preferably be designed to be active and / or passive, or have active and / or passive components.

[0044] According to the invention, at least one deceleration device is assigned to the collection section. Depending on its design, such a deceleration device is intended to weaken, dampen, or slow down the transfer energy or movement of the bag. For example, and preferably, a spring-loaded inlet funnel can be provided. Such a deceleration device preferably slows down the bags and delays their feed to the subsequent discharge device.

[0045] Preferably, the receiving section is arranged radially and / or rotated in the direction of rotation of the packaging machine. This allows for a particularly efficient transfer of a filled bag from the filling module or filling nozzle to the transfer device. Preferably, in the case of an arrangement rotated relative to the packaging machine, a slightly rotated or even tangential arrangement is provided.

[0046] In suitable designs, the damping element is assigned to and / or integrated into the deceleration device. In particular, it is also possible that, for example, a separate plate and / or a resilient plate section is assigned to or integrated into the deceleration device as a damping element. Haver & Boecker

[0047] Preferably, the conveying section is arranged (either) substantially transversely or in continuation of the collection section. It can therefore preferably also be arranged radially or in line away from the filling nozzle. The conveying section transports the bag to the discharge device, and is preferably equipped with a conveyor belt and / or a conveyor belt and / or another suitable conveying means. It is preferred that, as an alternative to a transverse arrangement, all other possible orientations are also provided. In particular, a linear continuation of the discharge is also preferred. Especially in the case of a linear continuation, the conveying section can also be provided by the discharge device.

[0048] Preferably, the conveyor section includes at least one carrier. Such a carrier serves, in particular, to convey the filled bag, which has been transferred onto the conveyor section, further towards the discharge device. This carrier can, for example, be designed like a plate, with the conveyor section then conveying the bags in sections. This method also preferably prevents the bag from tipping over.

[0049] Appropriate continuing education courses include at least two

[0050] Collection areas are provided, which are in particular assigned a common conveyor line. Depending on the specific configuration, such a design can significantly increase the performance of the packaging machine.

[0051] Preferably, the conveying section is arranged at least partially inclined, depending on the design. The inclination can be adapted to, or continue, the inclination of the collection section. Haver & Boecker

[0052] Preferably, at least one sealing device is included on the packaging machine for sealing the bags, particularly on each filling module. With such a design, the bags can be sealed directly on the packaging machine or on the respective filling module (directly) before being transferred to the transfer device.

[0053] The transfer device according to the invention is designed as described above and in particular comprises at least one receiving section with a delay device associated therewith.

[0054] The transfer device according to the invention also offers the advantages that have already been described previously for the packaging system according to the invention.

[0055] The method according to the invention is suitable for operating a packaging system as previously described. In this process, an empty bag or an empty valve bag is attached to a filling nozzle of a packaging machine and filled, the filled valve bag being fed from the filling module to the transfer device and gently transferred to the discharge device by means of the transfer device. For this purpose, the filled valve bag is conveyed at a predetermined speed by means of at least one deceleration device.

[0056] For this purpose, the bag is preferably slowed down by the deceleration device and / or conveyed at the predetermined speed, e.g., by an active conveying element. Particularly in the case of active conveying for deceleration, the bag can preferably also be removed from the filling nozzle by means of the transfer device, depending on the design.

[0057] The bag is preferably slowed down by means of at least one deceleration device. Such a Haver & Boecker

[0058] A delay device can enable a particularly gentle continuation of the bag transport.

[0059] The inventive method also offers the advantages that have already been described for the inventive packaging system.

[0060] Preferably, the bag is gently fed into at least one receiving section of the transfer device by means of at least one damping element. The damping element particularly dampens the impact that is otherwise typical and not gentle in such packaging systems, thereby significantly reducing the force input into the filled bag by the packaging system and the method according to the invention. This also makes it possible, among other things, to process bags that are not yet sealed or are open (e.g.,

[0061] to drop or deliver valve bags or open-face bags) from the packaging machine.

[0062] Further advantages and features of the present invention will become apparent from the exemplary embodiment, which is explained below with reference to the accompanying figures.

[0075] Fig. 12 is a purely schematic representation of an embodiment of a transfer device of a packaging system according to the invention in a top view.

[0076] Figure 1 shows a purely schematic embodiment of a packaging system 100 according to the invention. The packaging system 100 shown here comprises a packaging machine 200, which is designed here as a so-called rotary packaging machine 203.

[0077] Furthermore, the packing plant 100 includes a

[0078] Attachment device 500, which is suitable and designed to automatically shoot empty valve bags 400 onto an empty rotating filling nozzle 201 of the packaging machine 200.

[0079] In the embodiment shown here, the packaging machine 200 or the rotating packaging machine 203 comprises six filling modules 201, which are distributed essentially evenly around the circumference. Each of these filling modules 201 includes a filling nozzle 202, onto which a valve bag 400 can be shot. By means of the loading device 500, valve bags 400 with a pre-opened valve 401 are accelerated in a dispensing channel and shot onto a rotating filling nozzle 202.

[0080] The packaging machine 200 rotates in the direction of rotation 204 at a predetermined speed, wherein the packaging system 100 is configured such that an empty bag shot onto the filling nozzle 202 is preferably filled during a rotation of the packaging machine 200 and discharged onto or to a conveying device 300.

[0081] To make the transfer of the full sack 400 as gentle and smooth as possible, according to the invention, a device is installed between the Haver & Boecker packing machine.

[0082] A transfer device 1 is provided between the 200 and the transport device 300. This transfer device 1 is suitable and designed to transfer a filled valve bag 400 or another container such as an open bag, either still open or already closed, as gently and upright as possible to the transport device 300.

[0083] In the prior art, in rotating packaging machines, a so-called sack chair 205 of a filling module 201 with the fully filled sack is simply tilted forward upon reaching the discharge device 300, so that the filled sack 400 is accelerated radially and in the direction of rotation 204 (tangentially) and thrown onto the discharge device 3.

[0084] This can result in considerable forces acting on the filled 400-pound bag, leading to deformation and even dust shedding. This can disrupt or complicate the subsequent palletizing of the 400-pound bags. Furthermore, excessive dust shedding can alter the fill weight. Understandably, open bags cannot simply be tipped out; instead, they are preferably sealed beforehand during the rotation of the 200-pound packaging machine.

[0085] The inventive interposition of a transfer device 1 ensures that the valve bags 400 can be transferred particularly gently and upright from the filling nozzle 202 via the transfer device 1 to the discharge device 300. For this purpose, the transfer device 1 comprises a collection section 2 to which a delay device 4 is assigned.

[0086] The conveying device 300 comprises in particular at least one conveying element 301, by means of which the filled bags 400 Haver & Boecker

[0087] for example, they can be palletized or transported further in other ways.

[0088] Figure 2 shows, purely schematically in a perspective top view, a further embodiment of a packaging system 100 according to the invention.

[0089] In the embodiment shown here, the packaging system 100 also comprises a packaging machine 200, a mounting device 500 and a removal device 300.

[0090] Furthermore, in this embodiment, a transfer device 1 is also provided according to the invention between the packaging machine 200 and the discharge device 300, which is designed such that filled valve bags 400 can be transferred from the filling support 202 particularly gently or without excessive force being exerted on the discharge device 300. This makes it possible, in particular, to transfer even unsealed or open valve bags 400 or other open containers, depending on the configuration.

[0091] Figure 3 shows the embodiment according to Figure 2 again in a different perspective view. Here, the rotating packaging machine 203 can also be seen, from which filled bags 400 are gently transferred to the discharge device 300 by means of a transfer device 1.

[0092] It is further shown that each of the eight filling modules 201 includes a filling support 202. It is further shown that each filling module 201 in the illustrated embodiment includes a so-called sack chair 205, which can be tilted radially outwards, i.e., forwards, to transfer a filled sack onto the transfer device 1. Haver & Boecker

[0093] Furthermore, it is shown that the conveyor section 5 also includes a substantially horizontally oriented conveyor element 12, to which carriers 6 are attached at regular intervals. These carriers 6 assist the further transport of the filled bags to the discharge device 300 and also prevent the bags from tipping over.

[0094] Figure 4 shows a detailed, purely schematic, perspective view of the previously shown embodiment from the side. The transfer device 1 between the rotating packaging machine 203 and the discharge device 300 can be seen.

[0095] It is further shown here that the transfer device 1 includes a collection section 2, which in the embodiment shown here is arranged at a slight downward incline starting from the packaging machine 200. Thus, the collection section 2, which is arranged here essentially radially to the packaging machine 200, provides a kind of chute 7, so that the bags 400 dropped or transferred onto the collection section 2 are reliably conveyed to a conveyor section 5 of the transfer device 1.

[0096] The valve bags 400 are transferred to the transfer device 1 in an upright position, either standing on their bottom or in the filled position, and are then conveyed to the conveyor line 5 in this orientation. In the illustrated embodiment, the valve 401 of the valve bag 400, or at least the opening of the valve 401, is located above the fill level of the valve bag 400 until it is completely closed.

[0097] Since the valve bag 400 is conveyed on the bottom of the bag or on a narrow side, it is advantageous to provide a (lateral) guide 13 so that the bag 400 is not dislodged from the Haver & Boecker transfer device.

[0098] 1 can fall. The transfer device 1 here comprises a so-called inlet funnel 9 as a delay device 4, wherein the pivotable flaps 14 of the inlet funnel 9 in the illustrated design provide the lateral guides 13.

[0099] At the end of the conveyor section 5, the filled bags 400 then fall gently onto a spring element 301 of the conveying device 300, which is also arranged at a slight incline, for further processing or removal.

[0100] Figure 5 shows a purely schematic view of the transfer device 1 and the discharge device 300. Here, too, the conveying section 5 of the transfer device 1 can be seen, which is positioned perpendicular to the receiving section 2.

[0101] Furthermore, it is shown that the transfer device 1 here comprises a damping element 3 and a delay device 4.

[0102] The more detailed design and functionality are described in Figures 6A to 6D (top views).

[0103] Figure 6A shows that a filled and still open valve bag 400 accelerates radially outwards from the packaging machine 200 and in the direction of rotation 204 towards the transfer device 1.

[0104] The transfer device 1 includes a damping element 3 in the area where a filled bag 400 is taken over from the packaging machine 200. In the illustrated embodiment, this damping element 3 is designed as a spring-loaded plate 8, so that the tangential force 208 or the force acting in the direction of rotation 204 is dampened, cushioned, or buffered as gently as possible via this damping element 3. This allows Haver & Boecker

[0105] The aim is to prevent the still open bag 400 from impacting stationary or fixed components of the packaging system 100 without any damping. Damping can be achieved, in particular, by means of active and / or passive elements. Springs, dampers, and / or pneumatic elements are preferably used, for example.

[0106] Figures 6B, 6C and 6D below further show that the filled bag 400 is introduced relatively slowly into the collection section 2 by means of a delay device 4.

[0107] This delay device 4, which here comprises a spring-loaded funnel 9 or inlet funnel 9, allows the feed of the filled bags 400 onto the conveying line 5 to be controlled and / or separated. Furthermore, particularly gentle conveyance of the filled bag 400 can be achieved, since the radial force 209 is absorbed by the delay device 4 or, in this case, the inlet funnel 9.

[0108] Depending on the design, the damping element 3 can be configured as a separate component from the deceleration device 4, as in the illustrated embodiment. However, depending on the design, the damping element 3 can also be part of the deceleration device 4 or be integrated into it. In particular, it is possible that the rear part of the inlet funnel 9, located in the direction of rotation 204, has a resilient plate section or the like that can perform the function of the damping element 3 or provide the damping element 3 itself.

[0109] Figures 7 to 10 show a further embodiment of a packaging machine 200 according to the invention. In the embodiment described below, the Haver & Boecker

[0110] However, the packing machine 200 is not designed as a rotating packing machine 203 as in the two previously shown embodiments, but as a so-called row packer 206.

[0111] The embodiment of the packaging machine 200 shown here comprises two filling modules 201, which are arranged side by side and each has a filling support 202. Depending on the configuration, however, three, four or more filling modules 201 can also be arranged side by side.

[0112] In the illustrated embodiment, empty valve bags 401 are placed on or shot onto a filling nozzle and filled. Depending on the configuration, the packaging machine 200 can also be suitable and designed to fill open-face bags.

[0113] In the embodiment shown here, it is further illustrated that the bags 400 stand on a bag stand 205 during filling, which here includes a roller conveyor 207. The transfer device 1 is partially enclosed by the packaging machine 200, with the roller conveyor 207 providing the receiving section 2 for the transfer device 1.

[0114] Furthermore, the roller conveyor 207 is designed with a brake here, so that the roller conveyor 207 also provides the deceleration device 4 here.

[0115] Once a sack 400 is completely full, the corresponding sack chair 205 or roller conveyor 207 can be folded down or inclined, causing the sack 400 to move by gravity alone along the roller conveyor 207 or the collection section 2 towards the conveying section 5 of the transfer device 1. For this purpose, the rollers are arranged transversely to the direction of travel of the sack 400. Haver & Boecker

[0116] To slow down the bags and thus ensure gentle transfer, a braked roller conveyor 207 is provided as the deceleration device 4. Separate lateral guides 13 are provided to prevent the upright bags 400 from tipping over. In alternative configurations, an inlet funnel 9 can also be provided as the deceleration device 4, in which case separate lateral guides 13 are not strictly necessary.

[0117] Furthermore, it is shown that the conveyor section 5 is not provided by a continuous conveyor belt, but by individual belts 10. This makes it possible to arrange individual rollers 11 between the conveyor belts 10 in order to further simplify the lateral transport of the full bag 400 from the roller conveyor 207 or from the collection section 2 to the conveyor section 5.

[0118] Depending on the design, a delay device 4 can also be provided when using a non-rotating packaging machine 100, as shown, for example, in Figures 6A to 6D for the preceding embodiment. Any other suitable modification of a delay device 4 can also be expediently used to control the transfer of the filled bag 400 to the conveyor 5 or to time or delay the discharge.

[0119] Figure 7 further illustrates that the conveying section 5 comprises a substantially horizontal or slightly inclined conveying element 12, which assists the transport to the discharge device 300. In addition, in the illustrated embodiment, carriers 6 are arranged on the conveying element, which assist the transport and also prevent the filled bags 400 from tipping over. Haver & Boecker

[0120] Figures 8 to 10 show, by way of example, the transfer of a filled valve bag 400 from the filling nozzle 202 (Figure 8) via the transfer device 1 or the collection section 2 (Figure 9) to the conveying section 5 (Figure 10).

[0121] Figure 11 shows, purely schematically, a further embodiment of a packaging system 100 according to the invention in a perspective view.

[0122] The packaging machine 200 essentially corresponds to the design of the rotating packaging machine 203 of Figure 3, and the transfer device 1 or the collection section 2 with delay device 4 are provided in a comparable manner.

[0123] Unlike the design shown in Figures 2 to 5, the conveying section 5 is not provided perpendicular to the collection section 2, but continues in a linear orientation to the collection section 2.

[0124] The system is designed so that the upright valve bags 400 are gently picked up by the transfer device 1 and then transferred, lying on their backs, onto the conveyor line 5, with the valve 401 pointing upwards. In this orientation, the valve 401, or rather its opening, remains above the fill level of the valve bag 400, preventing any product from escaping, even if the valve is not yet closed.

[0125] Figure 12 shows, purely schematically, another embodiment of a transfer device 1 according to the invention with a

[0126] Collection section 2 and a delay device 4 are shown, the delay device 4 being provided here as well by a so-called inlet funnel 9. Haver & Boecker

[0127] The inlet funnel 9 is provided by two spring-loaded flaps 14, with a lateral guide 13 being realized on one side by one of the flaps 14 and on the other side by a damping element 3.

[0128] Furthermore, the figure shows that the tangential force 208 acting on the bag 400 to be transferred is absorbed by the damping element 3, and the deceleration of the radial force 209 is achieved by the deceleration device 4 or the inlet funnel. Haver & Boecker
