    Description: The invention lies in the field of transport and conveyor technology, in particular intra-logistics.
    According to a first aspect, the invention relates to a device for loading a hanging transport bag from above with a transport good, in particular with a piece goods. The device contains a feed device for feeding the goods to be transported into a transfer area of an overhead conveyor device. The overhead conveyor also contains a guide rail and transport bags that can be moved along the guide rail.
    The terms "above", "above" and "below", "below" refer to the direction of gravity.
    The terms "up", "from above" or "down", "from below" in connection with a movement means that a movement component is present in or against gravity.
    Furthermore, the invention according to the first aspect also relates to a method for loading a transport bag with a transport item, by means of the device according to the invention, wherein the transport bag is conveyed in the conveying direction in a hanging position in the transfer area, and the transport item by means of the feed device in the feed direction Transfer area is conveyed and transferred in a transfer direction from above through the receiving opening into the receiving compartment of the transport bag.
    In automated warehouses, extensive production facilities and the transportation of goods in general, there is a need to transport goods in suitable containers, then further convey them, for example via a hanging conveyor, and temporarily store them or transport them to their destination and unload them there.
    Overhead conveyors are also used in particular for the sorting and picking of articles. Picking is the compilation of a selection of articles from a total (assortment of articles). For example, picking can be based on a sales order or a production order.
    It is known from the prior art to use overhead conveyors with transport bags for the transport of articles or goods.
    [0009] Publication DE 10 2004 018 569 A1 describes, for example, a overhead conveyor device with a plurality of collapsible collecting bags for receiving and sorting collecting objects, in particular items of clothing. The collection bag comprises a frame and a pocket bag hanging on the frame. The collection bag is suspended from the overhead conveyor using a hook attached to the frame.
    The advantage of transport bags is that they are flexible. This allows the receptacle to be compressed or compressed, e.g. by folding it up. In this way, the transport bags allow space-saving goods logistics compared to rigid boxes and containers, for example. In this way, empty transport bags with a compressed storage compartment can be stored or transported to save space. The storage compartments only need to be expanded to take up space in order to transport or store goods.
    Suspended conveyors, like other conveyors, require space accordingly. However, this is often only available to a limited extent. Thus, space problems can occur in particular in the transfer area, in which a transport good is transferred into transport bags of the overhead conveyor. One of the reasons for this is that the overhead conveyor must share the available area with a conveyor that conveys the goods to be transported into the transfer area.
    The publication DE 10 2008 061 685 A1 describes a system with a loading station for transport bags, which are conveyed by means of a hanging conveyor. The loading station has an upper feed rail for the transport bags, a vertical conveyor connected to the upper feed rail for feeding the transport bags into a lower loading position, a device for opening the transport bags in the loading position and a lower one connecting to the vertical conveyor Guide rail for horizontal transport of the transport bags from the loading position. Since the goods to be transported are both conveyed horizontally and transported away horizontally in the transport bags, the system requires a comparatively large amount of space.
    It is now an object of the present invention according to the first aspect to propose a device for loading transport bags with a transport item, which takes up as little space as possible.
    The object is solved by the features of independent claims 1 and 10. The dependent claims, the description and the figures contain particular embodiments and developments of the invention.
    The inventive device is characterized in that the course of the guide rail is designed so that the transport bag after the transfer of the goods to be transported into the transport bag, if necessary after passing through a bag support arranged in the transfer area, hanging, in particular hanging freely, from the transfer area is transported upwards.
    [0016] Conveying away from the transfer area means a conveying process immediately after the transfer area.
    "Hanging" means that the transport bag is oriented vertically in the rest position or has an inclination with respect to a vertical which is 45 ° or less, in particular 35 ° or less and very particularly 30 ° or less. The inclination can be determined by a deflection element, e.g. Pocket rest, be forced.
    "Free hanging" means in particular that the transport bag is oriented vertically in the rest position and in particular is not forcibly deflected into an inclination by a deflecting element.
    The movement of the transport bag upwards immediately after the transfer area means in particular that the vertical movement component is at least the same as or greater than the horizontal movement component, if the latter is present at all.
    The transfer area corresponds to that area of the device in which the goods to be transported are transferred from the feed device to the transport bags of the overhead conveyor device, i.e. deliver or be handed over.
    The feed device and the overhead conveyor device are in particular designed and arranged relative to one another in such a way that the transport bag is moved into the transfer area in a hanging manner, in particular in a freely hanging manner.
    In the open position, the transport bag forms in particular a storage compartment for the goods to be transported, which is accessible from above via a receiving opening.
    The receiving compartment is during the transfer of the goods to be transported, i.e. in the transfer area, accordingly in an open position.
    The device therefore comprises in particular an opening mechanism by means of which the transport bag can be opened for the above-mentioned purposes. The opening mechanism can be designed such that the transport bag is opened in the conveying direction before the transfer area. The opening mechanism can also be designed so that the transport bag is only opened in the transfer area.
    The opening mechanism can comprise a control link, which acts on a control roller arranged on the transport bag and thus causes the bag to open. The control link can be stationary, the control roller being guided over the stationary control link while the transport bag is being conveyed into the transfer area.
    The transport bag can further comprise opening means, via which the receiving compartment, in particular against gravity or against a restoring force, can be moved into or held in the open position. Such opening means can include the control roller mentioned above. Furthermore, the opening means can also comprise sliding elements, pins, wire arches or wire eyelets.
    [0027] The transport bag comprises in particular a pocket rear wall forming the rear of the receiving compartment.
    The back wall of the pocket is in particular self-supporting or intrinsically stable. The back wall of the pocket is particularly rigid. The back wall of the pocket is particularly flat or planar.
    [0029] According to a further development, the rear wall of the pocket in the open position of the transport pocket forms a rear wall section which is extended beyond the storage compartment.
    The transport bag further comprises in particular a pocket front wall forming the front of the receiving compartment. The front wall of the pocket is in particular self-supporting or intrinsically stable. The back wall of the pocket is particularly rigid. The front wall of the pocket is, in particular, flat or even.
    The front wall of the pocket can be connected to the rear wall of the pocket via pocket side walls and a pocket bottom. In the open position, these also form the receiving compartment.
    The front wall of the pocket and the rear wall of the pocket can be moved in particular relative to one another in order to open and close the transport pocket.
    When opening, the transport bag is transferred in particular from a closed position, in which the front wall of the pocket is arranged in a compact position to the rear wall of the pocket, into an open position, in which the receiving compartment is expanded to form the receiving opening. The front wall of the pocket is spaced apart from the rear wall of the pocket in the open position.
    [0034] The pocket rear wall and / or the pocket front wall and in particular the entire transport pocket can for example comprise a frame. To form the walls, the frame can be covered with a flat structure, in particular a textile flat structure, such as fabric.
    The frame is particularly rigid. The frame can be made of wire or a rod.
    According to a development of the invention, the direction of transfer of the goods to be transported into the transport bag and the conveying direction or path of the transport bag from the transfer area lie in a common plane.
    According to a further development of the invention, the transfer direction of the transport goods into the transport bag and the conveying direction or path of the transport bag into the transfer area lie in a common plane.
    [0038] The direction of transfer is to be understood as the direction in which the goods to be transported move from the feed device into the transport bag.
    [0039] The transport bags are connected in particular to a conveyor element which can be moved along the guide rail.
    [0040] The guide rail runs in particular essentially horizontally and very particularly horizontally towards the transfer area. Essentially horizontal also includes inclinations of the guide rail which deviate from the horizontal by 10 ° (degree of angle) or less, in particular 5 ° or less.
    The guide rail forms, in particular, a bend section in the transfer area. In the bending section, the transport pockets are deflected along a curved path from a feed direction to a discharge direction.
    The transport bags are deflected in the bend section in particular from a horizontal or substantially horizontal movement or feed direction in an upward, in particular obliquely upward movement or removal direction.
    [0043] According to one embodiment of the invention, the guide rail forms a particularly inclined removal section immediately after the bending section in the transfer area. The guide rail has an angle of 45 ° or more, in particular 60 ° or more, in relation to a horizontal in the conveying section. The angle can also be 90 ° or less than 90 °.
    This means that the transport bags are conveyed upwards out of the transfer area at the named angle.
    The overhead conveyor is designed for hanging, in particular at least in sections freely suspended conveying of the transport bags. The overhead conveyor device comprises in particular a plurality of transport bags which can be moved one behind the other in the conveying direction along a guide rail.
    The overhead conveyor is designed in particular for the individual conveying of the transport bags. The term "individual" means that the transport bags or their conveying elements are not directly connected to each other, e.g. are chained.
    The overhead conveyor can, viewed in the direction of conveyance, contain a separating mechanism in front of the transfer area, by means of which the e.g. in a storage space or along a storage section in front of the separating mechanism, transport bags which are held individually can be released or conveyed into the transfer area.
    The separating mechanism can comprise a release member which releases the transport bag. The release member can form a movable stop on which the transport bags are retained. To release a transport bag, the stop can be moved into a corresponding release position. The release member or its stop is controlled in particular by a controller.
    [0049] The separating mechanism can include a screw conveyor, by means of which the individual transport bags are conveyed to the transfer area.
    The screw conveyor is rotatably mounted about an axis of rotation arranged parallel to the direction of conveyance.
    A helical or screw-shaped guide groove is arranged along the outer circumference of the screw conveyor. The guide groove serves to receive a driving element, such as driving cams, arranged on the conveyor element. This engages in the guide groove and is carried along with the conveyor element and the transport bag hanging on it by the guide groove rotating with the screw conveyor along the axis of rotation of the screw conveyor.
    When viewed in the conveying direction, a storage section can be formed in front of the separating mechanism, in which the accumulating transport bags are retained.
    [0053] The overhead conveyor device can also contain a carrier conveyor with at least one and in particular several carriers for driving the conveyor member and thus the transport bag connected to it in the conveying direction. The at least one driver can be arranged on a, in particular rotating driver element, such as a driver chain. Thus, several drivers can be arranged one behind the other and at a distance from one another along the driving element. The at least one driver can be a driver cam.
    The driving conveyor is arranged in particular in the conveying direction after the separating mechanism and in particular after the screw conveyor. The separation mechanism or the screw conveyor transfers the transport bags, in particular, to the transport conveyor.
    The conveying member can contain a contact element for forming a driving contact with the driver of the driving conveyor.
    The entraining conveyor is actively driven by a drive.
    [0057] The entrainment conveyor is used in particular to actively promote the transport bags after the transfer area upward against the force of gravity along the guide rail. The transport conveyor therefore corresponds in particular to an upward conveyor.
    The entrainment conveyor can also serve to actively promote the transport bags along the guide rail into the transfer area. The conveyance by the entraining conveyor, viewed in the direction of conveyance, takes place in particular after the separating device, in particular after the screw conveyor.
    The entrainment conveyor can also actively promote the transport bags along the guide rail in the transfer area.
    The feed device in particular forms a conveying surface on which the goods to be transported rests. The conveying surface can be continuous or interrupted.
    The feed direction or the conveying surface runs in particular horizontally or essentially horizontally. Essentially horizontal means that the feed direction deviates 10 ° or less, in particular 5 ° or less, from a horizontal.
    The feed device contains in particular at least one conveyor unit, which forms a conveyor surface. The conveying surface is in particular formed by a rotating conveying element. The conveyor can be driven.
    The conveyor can be flat. The conveyor can be a conveyor belt, a mat chain or a roller conveyor.
    [0064] The feed device is designed in particular to feed the transported goods individually or in portions to the transfer area. The goods to be transported are transferred individually or in portions from the feed device into the individual transport bags. For this purpose, the transported goods can be conveyed to the transfer area individually or in portions in compartments or compartments of the feed device.
    The transported goods can be a (portioned) bulk goods, such as powder, granules, small parts (e.g. screws), etc. However, the goods to be transported include in particular piece goods, i.e. individual discrete objects. These items can be household items, sports items, clothes, shoes, packaged items, filled bags (mailing bags) or containers such as boxes or boxes. Correspondingly, the transport bags can be loaded with individual piece goods.
    The transfer area can be arranged at the head end of a deflection point of the conveyor element of the feed device. At the deflection point, the conveying member is deflected in particular downwards.
    According to a development of the invention, the feed device contains a plurality of feed units arranged one behind the other in the feed direction, each of which forms a feed surface. The conveyor units each include in particular a rotating conveyor. The funding bodies can be individually driven.
    [0068] According to a development of the invention, the conveying path of the transported goods conveyed by the feed device can overlap with the conveying path of the transported goods conveyed away in the transport bags.
    In such a case, the feed device for releasing the conveying path of the transport bag to be conveyed away from the transfer area can contain a conveying section which can be moved away from a feed position. The feed position corresponds to the position which the said conveying section takes during the transfer of a transport good into the transport bag.
    Said conveyor section can in particular be pivoted away from the transfer position. Said conveyor section can be formed by a conveyor unit.
    The feed device contains, in particular, a conveyor unit which closes towards the transfer region and which can be moved, in particular pivoted away, from a transfer position to release the conveying path of the transport bag to be conveyed away from the transfer region.
    The final conveyor unit can comprise a rotating conveyor element, as already described above. The final conveyor unit can also include a roller conveyor, via which the goods to be transported are transferred into the transport bags.
    The transport bag is arranged with its leading receiving compartment in the transfer area viewed in the conveying direction of the transport bag, in particular frontally in front of the feed device.
    [0074] The device or the feed device can form a pocket support on which the transport pocket lies or rests in the transfer area, in particular with the pocket front wall. The transport bag lies flat on the bag support, in particular.
    The support surface of the pocket support can form a horizontal angle of 45 ° or more, in particular 60 ° or more. The angle is also in particular less than 90 °.
    [0076] As a result, the transport bag in the transfer area can be stabilized with regard to the transfer of the goods to be transported. Any swinging of the transport bag is thereby stopped in the transfer area.
    In addition, the support surface can already decrease the inclination of the loaded transport bag, which takes it anyway due to the center of gravity in front of the suspension point in a freely hanging position. As a result, swinging of the transport bags after the transfer area can be prevented or at least reduced.
    The bag support can also be designed so that the transport bag rolls up or slides upwards when it is conveyed away from the transfer area after the transfer of the goods to be transported on the bag support.
    The pocket support accordingly correspondingly forms a support surface. The support surface can directly adjoin the conveying surface of the feed device.
    The pocket support can also correspond to an end section of a conveying surface of the feed device or can be part of a final conveying unit.
    The pocket support can form a roller conveyor. This has the advantage that the transport bag moved out of the transfer area T can roll on the roller conveyor with its pocket front wall, in particular against the transfer direction.
    If the pocket support is formed from an end section of a conveying surface or a final conveying unit, the roller conveyor can also be designed so that the goods to be transferred into the transport pocket roll off in the direction of transfer over the roller conveyor.
    The pocket support can have an inclination with respect to a vertical one. The pocket support can also be aligned vertically.
    The invention further relates to a method for loading a transport bag with a transport item. The method is operated in particular by means of a device described above.
    According to the method, the transport bag is suspended in the conveying direction, in particular freely suspended, moved into the transfer area or enters it.
    The transport bag is conveyed via the conveyor element along the guide rail into the transfer area.
    The transport bag is in particular conveyed substantially horizontally or horizontally into the transfer area. Essentially horizontal also includes inclinations that deviate from the horizontal by 10 ° or less, in particular 5 ° or less.
    [0088] The transport bag can also be conveyed along a slope into the transfer area. The favor in particular allows gravity-assisted funding. In this case, the transport bag can even be used independently, i.e. be promoted to the transfer area without active drive.
    [0089] However, it is also possible for the transport bag to be actively conveyed into the transfer area by means of a transport conveyor.
    [0090] The transport bags are in particular conveyed individually into the transfer area. For this purpose, the transport bags can be released individually in the conveying direction to the transfer area via the separating mechanism.
    The transport bag is moved with the receiving opening in the conveying direction in front of the pocket rear wall into and through the transfer area.
    This means that the transport bag is moved with the receiving opening in the conveying direction in front of the bag rear wall into the transfer area and out of the transfer area.
    [0093] The transport bag is opened in front of or in the transfer area. The transport bag is opened actively using the opening mechanism mentioned.
    According to a further development of the method, the conveying movement of the transport bag is stopped in the transfer area. This means that the transport bag is stopped from the feed device into the receiving compartment of the transport bag for the purpose of transferring the goods to be transported. This is done in particular by stopping the transport conveyor.
    The transport bag can be stopped in front of a bend section in the transfer area. The transport bag can be stopped in a bend section in the transfer area. The transport bag can be stopped after a bend in the transfer area.
    Accordingly, the transport bag is in the transfer area in a defined transfer position along the conveyor path of the overhead conveyor for the purpose of transferring the goods to be transported.
    The goods to be transported are conveyed to the transfer area in the feed direction by means of the feed device and are transferred in a transfer direction from above through the receiving opening into the receiving compartment of the transport bag. Accordingly, the pocket opening is located below the conveying surface of the feed device.
    The transfer direction includes in particular a direction component in the direction of gravity. Correspondingly, the goods to be conveyed in the transfer area are transferred from the feed device into the transport bag in the transfer direction with the aid of gravity.
    The transfer of the goods to be transported can take place by means of a guided movement, for example over an inclined conveying surface. The transfer of the goods to be transported can also be carried out by means of an unguided movement, e.g. a free fall.
    After the transfer of the goods to be transported into the transport bag, the transport bag is carried away hanging upwards.
    The transport bag is conveyed away from the transfer area in particular along the guide rail via the conveyor element.
    According to a further development of the invention, the transport bag is essentially moved against the transfer area immediately after the transfer area, in particular against the direction of transfer of the goods to be transported into the transport bag from the transfer area.
    Substantially opposite to the transfer direction means that the two directions can form an angle of 15 ° or less, in particular 5 ° or less.
    If the conveying path of the transport bag conveyed away from the transfer area intersects the conveying path of the goods to be conveyed by the feed device, then the relevant conveying section of the conveying device is moved from its conveying position into a release position, in particular pivoted away, to release the conveying path of the transport bag to be conveyed away from the transfer area.
    The device according to the invention has the advantage that the transport bags are conveyed upwards immediately after the transfer of the goods to be transported and thus out of the conveying plane of the feed device. In this way, the conveying paths of the overhead conveyor and feeder run in a space-saving manner on different levels. As a result, the device according to the invention requires less installation space.
    [0106] Furthermore, by conveying the filled transport bag upwards, space is immediately released for a subsequent transport bag. This can speed up the filling process.
    A further aspect of the invention relates to a overhead conveyor device containing a guide rail and at least one transport bag for the hanging transport of a transport good, in particular a piece good, along a conveying path, the at least one transport pocket being connected via a connecting structure to a conveying member which can be moved along the guide rail.
    Transport bags generally have hanging hooks, via which they can e.g. are attached to a roller-guided conveyor. This also applies, for example, to the two publications cited at the beginning.
    The suspension of the transport bags via a suspension hook means that they swing freely with respect to the conveyor element. This means that the transport bag can swing in or against the conveying direction as well as transversely to the conveying direction.
    As a rule, inertial forces cause the transport bags to vibrate. Inertial forces occur, for example, when the transport bag is accelerating or braking along the transport route. Furthermore, the transport bag can also be set to vibrate when the direction changes.
    A freely swinging suspension of the transport bag has advantages. The above-mentioned forces are converted into kinetic kinetic energy by swinging. In the case of a rigid suspension of the pockets, on the other hand, forces would act on the connection between the transport pocket and the conveyor element and also on the rail-guided conveyor element. The consequence of this would be high frictional forces between the conveyor element and the guide rail and correspond to high wear, as well as high stress on the connection between the transport bag and the conveyor element.
    The object of the present invention according to the second aspect of the invention is therefore to propose a slope conveyor device in which the disadvantages of a freely swinging transport bag no longer occur or are at least limited. Nevertheless, the transport bag should not be rigidly suspended from the conveyor element and should have the above-mentioned advantages of a freely swinging transport bag.
    [0113] The object is achieved with the features of independent claim 16. The dependent claims, the description and the figures contain particular embodiments and developments of the invention.
    The invention according to the second aspect is characterized in that the connection structure contains a swivel body and a connection body, the transport bag being fastened to the swivel body. The connecting body, on the other hand, is connected to the conveyor element.
    The swivel body is now connected to the connecting body via a swivel connection, in such a way that the swivel body can be pivoted with respect to the connecting body transversely to the conveying direction. Accordingly, the transport bag attached to the swivel body can be swiveled transversely to the conveying direction via the swivel body.
    According to a further development of the invention, the connecting body contains swivel stops for limiting the swivel angle of the swivel body.
    [0117] The swivel body in turn can form swivel delimitation surfaces. The swivel limiting surfaces are stopped at the swivel stops to limit the swivel angle of the swivel body when a maximum swivel angle is reached. This means that the swivel angle is limited by hitting the swivel limiting surfaces on the swivel stops.
    The maximum swivel angle can be 60 ° or less, in particular 45 ° or less, and very particularly 25 ° or less. The swivel angle corresponds to the angle of the swivel movement between a left and right swivel stop in the conveying direction.
    The pivot stops can include damping elements, e.g. made of rubber-elastic plastic, spring elements or gel, which dampen the impact of the swivel body on the swivel stops and absorb kinetic energy.
    The pivot limiting surfaces can include damping elements, e.g. made of rubber-elastic plastic, spring elements or gel, which dampen the impact of the swivel body on the swivel stops and absorb kinetic energy.
    [0121] The connecting body can be in one or more parts. The connecting body can be made of metal, e.g. Steel.
    According to a development of the invention, the connecting body can form a swivel guide for a guided swiveling movement of the swivel body transversely to the conveying direction. The swivel guide is intended in particular to prevent swiveling of the swivel body in or against the conveying direction.
    The swivel guide comprises in particular a first guide element arranged in front of the swivel body, viewed in the conveying direction, and a second guide element arranged after the swivel body. The guide elements are in particular guide walls.
    The swivel body is arranged at least via a swivel body section between the first and second guide elements.
    According to a development of the invention, the connection structure is designed in such a way that it prevents the transport bag from rotating about its central longitudinal axis. This can be done, among other things, by the aforementioned swivel guide.
    The swivel body is connected to the connecting body in particular via a (physical) swivel axis. The connection is particularly detachable and can be a screw connection, for example.
    The pivot axis forms a pivot bearing for the pivot body on the connecting body.
    [0128] The swivel axis is aligned in particular parallel to the conveying direction.
    The pivot axis is in particular guided by the above-mentioned first and second guide element and by the pivot body section arranged between the two guide elements.
    According to a special embodiment, the connecting body is U-shaped. The U-shaped connecting body comprises two side walls and a connecting wall which connects the two side walls to one another.
    The swivel body is pivotably mounted at least with a swivel body section between the side walls transversely to the conveying direction.
    The two side walls are in particular part of the swivel guide mentioned above and correspond to the guide elements or guide walls mentioned.
    The swivel body is guided with at least one swivel body section into a swivel space of the U-shaped connection body formed by the two side walls and the connecting wall.
    The pivot axis is guided through the side walls of the U-shaped connecting body and through the pivot body section arranged between the two side walls.
    The connecting body is connected in particular to the conveying member via the connecting wall. The connection can be releasable and can comprise, for example, a screw connection.
    [0136] The swivel body can be formed in one or more parts. The swivel body consists in particular of plastic or metal. The swivel body can be an injection molded part.
    The swivel body forms in particular a bracket receptacle for a bracket or for a bracket section of a bracket of the transport bag.
    The length of the bracket receptacle, which extends transversely to the conveying direction in the operating position, is in particular a multiple of the largest diameter of the bracket receptacle measured parallel to the conveying direction. The length of the bracket receptacle can in particular be at least five times the diameter of the bracket receptacle mentioned.
    [0139] The transport bag is pivotally mounted in the bracket receptacle, in particular in or against the conveying direction, via the bracket or the bracket section. The bracket is made of wire in particular.
    The holding bracket can be rigidly mounted transversely to the conveying direction, that is to say it cannot be pivoted in the bracket receptacle.
    [0141] The holding bracket or the holding bracket section, which is held in the bracket receptacle, is particularly round in cross section, such as oval or circular.
    [0142] According to one embodiment variant, the swivel body can form a slit-shaped bracket receptacle that is open towards the connecting body and is used to mount the retaining bracket. For this purpose, the swivel body can in particular be U-shaped.
    The retaining bracket can be secured against shifting in the direction of the conveying member by means of securing elements, such as spring steel dowel pins which are guided transversely through the slot-shaped bracket receptacle.
    [0144] According to one embodiment variant, the swivel body can comprise two, in particular identical, joining elements, which are connected to one another to form the swivel body, forming a bracket receptacle for the retaining bracket.
    [0145] The bracket receptacle can be designed in such a way that the swivel body completely surrounds the retaining bracket at least in sections. This means that the swivel body is designed at least in sections as a through opening.
    [0146] According to a special embodiment variant of the bracket receptacle, the swivel body comprises the retaining bracket over the entire length of the bracket receptacle. This means that the bracket receptacle is designed as a through opening over its entire length.
    [0147] The swivel body or the bracket receptacle can include the retaining bracket in particular at least in sections or over the entire length essentially in a form-fitting manner.
    The bracket can only be held in the bracket receptacle with slight radial play. This allows the bag to pivot freely in and against the conveying direction.
    The bracket can also be held in the bracket receptacle only with a little lateral play. This allows only a slight lateral displacement of the bracket relative to the swivel body.
    It can also be provided that the bracket receptacle does not rigidly hold the bracket.
    [0151] According to an embodiment variant of the bracket holder, the bracket holder can have a V-shaped holder section or be designed as a V-shaped holder. The inclined side flanks of the V-shaped bracket section or the V-shaped bracket holder run downwards in the operating position, i.e. in the direction of gravity, together.
    The bracket receptacle can have another, e.g. Form rectangular, receiving section, which forms the bracket receptacle together with the V-shaped receiving section.
    The bracket receptacle according to this embodiment variant has in particular a cross-sectional area which is a multiple of the cross-sectional area of the bracket to be received.
    The V-shaped receptacle section or the V-shaped receptacle allows the holding bracket to move out of a defined conveying position in the region of the meeting inclined flanks with special external force, such as occurs, for example, when cornering in the form of centripetal forces. Thus, the V-shaped receiving section or the V-shaped receptacle allows the holding bracket to escape along its inclined, lateral flanks from its defined conveying position.
    As soon as a particular external force decreases again, the V-shaped configuration of the bracket receptacle or a section ensures that the retaining bracket returns to its defined conveying position.
    The V-shaped receptacle section or the V-shaped receptacle thus also ensures that the holding bracket assumes a defined conveying position due to gravity in the absence of any special external force. In the operating position, the defined conveying position corresponds in particular to the lowest point of the V-shaped receiving section or the V-shaped receiving device.
    In this way, local force peaks that originate from the holding bracket can be avoided or reduced, which would act directly on the swivel body if the holding bracket were held rigidly.
    The limited cross-sectional area of the bracket receptacle also places limits on the evasive movement of the retaining bracket, so that the pocket cannot deflect as much as desired and thereby impair the conveying operation.
    [0159] The overhead conveyor device with the connection structure according to the second aspect of the invention can be used in particular in a device according to the first aspect of the invention.
    The suspension of the transport bag on the conveyor element according to the invention has the advantage that the transport bag can freely swing across the swivel body transversely to the conveying direction in a defined swivel angle. In this way, tilting forces acting on the conveyor element can be avoided or reduced. This is because these forces lead to increased wear on the conveyor element, in particular on impellers or sliding elements of the conveyor element and possibly also on the guide rail.
    [0161] However, the swivel angle of the transport bag is limited according to the invention, so that the transport bag cannot swivel out to the side as far as desired and possibly collide with plant parts or other transport bags. This is particularly important in the storage rooms of the overhead conveyor for the (temporary) storage of the empty or filled transport bags, in which the space is generally limited and lateral swiveling of the transport bags is only possible to a limited extent.
    The conveyor of the overhead conveyor according to the two aspects of the invention described above is in particular a carriage with rollers over which the carriage is guided in a rolling manner along at least one guide rail designed as a guide rail.
    The carriages can be designed as external or internal runners.
    The carriages are designed in particular as individual carriages. Single carriage means that the carriages are not directly connected to each other, e.g. are chained. This allows individual transportation of the transport bags.
    [0165] The two aspects of the invention are explained in more detail below on the basis of exemplary embodiments which are illustrated in the accompanying figures. Each shows schematically:

    In principle, the same parts are provided with the same reference symbols in the figures. To understand the invention, certain features are not shown in the figures.
    The described exemplary embodiments are examples of the subject matter of the invention and have no restrictive effect. In particular, the transport bags shown in the present figures are only exemplary. Other designs of transport bags are also conceivable.
    The device 1 according to the invention according to FIG. 1 comprises a hanging conveyor device 20 and a feed device 10, which together form a transfer area T.
    [0168] The overhead conveyor device 20 comprises a plurality of transport bags 21, each of which has a holding bracket 26. The transport bags 21 are each connected to a carriage 40 by means of the holding bracket 26 via a connecting structure 70.2 according to the second embodiment variant. Of course, a connection structure 70.1 according to the first embodiment is also possible.
    The carriage 40 comprises rollers 45, over which it rolls for the purpose of conveying the transport bag 21 along a guide rail 41 of the overhead conveyor 20.
    The hanging conveyor device 20 has a separating mechanism 90 with a conveyor screw 91 in the conveying direction F in front of the transfer area T. A conveyor or upward conveyor 15 connects to the screw conveyor 91. The transport bags 21 are moved individually into the transfer area T by the driving conveyor 15.
    The driving conveyor 15 is designed as a cam concentric, which is operated in a clocked manner. The cam concentricity is characterized by a cam chain, on which a plurality of driver cams are arranged one behind the other and spaced apart.
    In front of the separating mechanism 90, a storage section 92 is formed, in which the transport bags 21, which are placed towards the separating mechanism 90, are retained until they are conveyed into the transfer area T. The functioning of the separation mechanism 90 and the screw conveyor 91 has already been explained in the general description part.
    The guide rail 41 and corresponding to the conveying path of the transport pockets 21 run horizontally towards the transfer area T. The guide rail 41 forms a bending section in the transfer area, in which the transport pockets 21 are deflected in a curved path from a horizontal direction of movement into an obliquely upward direction of movement.
    The feed device 10 comprises a plurality of conveyor units 11 arranged one behind the other in the feed direction Z, each with a conveyor belt 12. The conveyor units 11 form a conveyor surface for the goods 2 to be conveyed into the transfer area T.
    In the transfer area T, the feed device 10 contains a final conveyor unit 13 in the form of a roller conveyor, via which the transported goods 2 roll and can slide or slide into the transport bag 21 from above.
    [0176] The transport bag 21 contains a rear wall 24 of the bag trailing in the direction of conveyance F and a front wall 27 of the bag which are connected to one another via the side walls 28.1, 28.2 of the bag and a bottom 29 of the bag.
    The pocket back strap 24 and the pocket front wall 27 together with the pocket side walls 28.1, 28.2 and the pocket bottom 29 in the open position form an upwardly open receiving compartment 23 with a corresponding receiving opening 22 (see also FIGS. 2a and 2b).
    The transport bag 21 also forms an extended rear wall section 24.1 towards the carriage 40, on which the holding bracket 26 is arranged.
    Both the pocket rear wall 24 and the pocket front wall 27 are inherently stable, i.e. trained self-supporting.
    The carrying bag 21 has a frame made of wire, which is covered with a fabric to form the walls 24, 27, 28.1, 28.2.
    The transport bag 21 according to the present embodiment can be opened from a closed position (FIG. 2b), in which the pocket front wall 27 is set back to the pocket rear wall 24, into an open position (FIG. 2a), in which the storage compartment 23 is formed vice versa.
    [0182] The transport bag 21 further contains control rollers 30 which, in cooperation with an opening mechanism, such as a control link, (not shown) serve to open the transport bag 21.
    The transport bag 21 is connected to a carriage 40 via the holding bracket 26. For this purpose, the holding bracket 26 is fastened with a bracket section to a connecting structure 70.2, which in turn is connected to the carriage 40.
    The connection structure 70.2 or 70.1 is described in more detail in connection with FIGS. 3 to 7 in the context of the second aspect of the invention.
    In carrying out the method according to the invention, in each case a single transport bag 21 is moved into the transfer area T along a feeding conveying path in the conveying direction F with the receiving compartment 23 advancing in the conveying direction F.
    The transport bag 21 is actively opened in front of or in the transfer area T by means of an opening mechanism (not shown).
    The transport pocket 21 lies in the transfer area T with its pocket front wall 27 of the final conveyor unit 13 of the feed device 10. which consequently forms a pocket pad.
    As soon as the transport bag 21 has reached the transfer area T, the conveyance of the transport bag 21 for the purpose of transferring a transport good 2 is stopped. The transport bag is consequently not in a conveying movement during the transfer of the transport goods 2 into the transport bag 21.
    [0189] A transport material 2 lying on the conveying surface of the conveying units 11, 13 is conveyed to the transfer area T via the feed device 10. The transported goods 2 slide over the roller conveyor of the final conveyor unit 13 in a transfer direction R through the receiving opening 22 into the receiving compartment 23.
    After the transfer of the transport goods 2 into the transport bag 21, the transport bag 21 with the transport goods 2 is moved obliquely upwards out of the transfer area T by means of the driving conveyor 15 along the bending section of the conveyor rail along a curved path from the horizontal conveying. In this process, the transport bag 21 rolls with its bag front wall 21 on the roller conveyor of the final conveyor unit 13.
    The final conveyor unit 13 with the roller conveyor can be pivoted away from its conveying position to release the conveying path for the transport bag 21 loaded with the transport goods 2.
    As soon as the transport bag 21 loaded with the transport goods 2 is conveyed upward out of the transfer area T, a subsequent transport bag 21 can be conveyed into the transfer area T.
    This is the case when the transport bag 21 loaded with the transport goods 2 is moved out of the transfer area T by at least one bag length.
    3 and FIGS. 5a and 5b each show a first embodiment variant of a connection structure 70.1 according to the second aspect of the invention.
    4, 6a, 6b and 8 each show a second embodiment variant of a connection structure 70.2 according to the second aspect of the invention.
    9 shows a third embodiment variant of a connection structure 170 according to the second aspect of the invention. The third embodiment variant basically corresponds to the second embodiment variant and differs from it only in the configuration of the bracket receptacle 74.3 for the retaining bracket 26. Accordingly, the third embodiment variant contains all the features of the second embodiment variant with the exception of the configuration of the bracket receiver, even if this is shown in the single FIG. 9 not all are shown.
    According to the three design variants, the connection structure 70.1, 70.2, 70.3 comprises a swivel body 71.1, 71.2, 71.3, which is connected to a connection body 72 via a swivel axis 73.
    The swivel body 71.1, 71.2, 71.3 is an injection molded part made of plastic or metal, which has reinforcing ribs to increase the strength.
    The swivel body 71.1, 71.2.7F3 has, in a swivel body section directed towards the connecting body 72, so-called swivel limiting surfaces 76 which strike a swivel stop 75 on the connecting body 72 when a maximum permissible deflection is reached.
    The connecting body 72 is U-shaped and comprises two lateral guide walls 77.1, 77.2, which are connected to one another via a connecting wall 78 and form a pivoting space 79.
    A swivel body section of the swivel body 71.1, 71.2, 71.3 is arranged in the swivel space 79 of the connecting body 72 and is flanked by the two guide walls 77.1, 77.2.
    [0202] The guide walls 77.1, 77.2 form a guide for the swivel body 71.1, 71.2, 71.3. The connecting wall 78 forms the pivot stop 75 for the pivot limiting surfaces 76.
    A pivot axis 73 oriented parallel to the conveying direction F is guided through the two guide walls 77.1, 77.2 and the pivot body section arranged between them. The pivot axis 73 connects the pivot body 71.1, 71.2, 71.3 to the connecting body 72. In addition, the pivot axis 73 forms a pivot bearing for the pivot body 71.1, 71.2, 71.3 on the connecting body 72.
    The pivot axis 73 has a screw thread, which enables the pivot axis 73 to be fastened to the connecting body 72 by means of a screw nut 82.
    The connection body 72 is connected to a carriage 40 via the connection wall 78. The connection is a detachable screw connection with screw nuts 83.
    The swivel body 71.1, 71.2, 71.3 forms a bracket receptacles 74.1, 74.2, 74.3 for receiving a bracket 26 or a bracket section. The length L of the bracket receptacle 74.1, 74.2, 74.3, which extends transversely to the conveying direction F in the operating position, is a multiple of the largest diameter D of the bracket receptacle 74.1, 74.2, 74.3 measured parallel to the conveying direction.
    According to the first embodiment variant according to FIGS. 3 and 5a and 5b, the swivel body 71.1 is formed in one piece and has a slit-shaped bracket receptacle 74.1 for the retaining bracket 26 which is open towards the connecting body 72 and extends transversely to the conveying direction F.
    To attach the retaining bracket 26 to the pivot body 72, a retaining bracket section is inserted into the slot-shaped bracket receptacle 74.1, which is open on one side, before the mounting of the pivot body 71.1 on the connecting body 72.
    The bracket 26 and with this the transport bag 21 is pivotally mounted in the bracket receptacle 74.1 of the swivel body 71.1 in and against the conveying direction F relative to the swivel body 71.1.
    The bracket receptacle 74.1 has a trough-shaped receiving base, which is formed opposite to the support cross section of the, in particular circular, cross section holding bracket 26. This geometry guarantees a flat support of the bracket 26 in the bracket receptacle 74.1.
    The bracket 26 is also rigidly or immovably mounted transversely to the conveying direction F, so that pivoting in the bracket receptacle 74.1 transversely to the conveying direction F is not possible.
    For the rigid mounting of the bracket 26 transversely to the conveying direction F, inter alia, dowel pins 81, which are embedded in the swivel body 71.1 and are guided transversely through the slot-shaped bracket receptacle 74.1. The dowel pins 81 are made of spring steel and are clamped in through openings on the swivel body 71.1.
    The clamping pins 81 prevent displacement of the holding bracket 26 in the direction of the connecting body 72.
    [0214] According to the second and third embodiment variants according to FIGS. 4, 6a. 6b, 8 and 9, the swivel body 71.2, 71.3 is formed in two parts and comprises a first, shell-shaped joining element 80.1, 180.1 and a second, shell-shaped joining element 80.2, 180.2.
    The joining elements 80.1, 80.2; 180.1, 180.2 are of identical construction in terms of their geometry and are designed such that they can be joined to form a swivel body 71.2, 71.3, with the formation of a bracket receptacle 74.2, 74.3 for the retaining bracket 26 extending transversely to the conveying direction F.
    To attach the bracket 26 to the swivel body 72, a bracket section before mounting the swivel body 71.2, 71.3, i.e. before joining the joining elements 80.1, 80.2; 180.1, 180.2, in the area of the bracket receptacle 74.2, 74.3 to be formed between the two joining elements 80.1, 80.2; 180.1, 180.2 inserted.
    The bracket 26 and with this the transport bag 21 is pivotally mounted in and against the conveying direction F in the bracket receptacle 74.2, 74.3 of the swivel body 71.2, 71.3.
    According to the second embodiment variant according to FIGS. 4, 6a, 6b and 8, the holding bracket 26 is rigidly or immovably mounted transversely to the conveying direction F, so that pivoting in the bracket receptacle 74.2 transversely to the conveying direction F is not possible.
    This is achieved, among other things, in that the retaining bracket 26 in the bracket receptacle 74.2 is fully encompassed by the pivot body, in particular essentially in a form-fitting manner, on the lateral end sections of the pivot body 71.2. Here, the retaining bracket is held in the bracket receptacle 74.2 with only a slight play, which allows the bag to be swiveled freely in and against the conveying direction.
    The joining elements 80.1, 80.2 according to the second embodiment also have connection openings and oppositely arranged connecting pins which engage in the connection openings when the joining elements 80.1, 80.2 are joined and thus connect the two joining elements 80.1, 80.2 to form the swivel body 71.2. The connecting pins also also restrict the movement of the holding bracket 26 in the direction of the connecting body 72.
    According to the third embodiment variant according to FIG. 9, the swivel body 71.3 has a bracket receptacle 74.3 in the lateral end sections, the cross-sectional area of which is a multiple of the cross-sectional area of the bracket to be received. The bracket receptacle 74.3 forms a V-shaped receiving section, the inclined side flanks of which in the operating position are down, i.e. converge in the direction of gravity. The bracket receptacle 74.3 furthermore forms a further rectangular receiving section above the V-shaped receiving section, which, together with the V-shaped receiving section, forms the bracket receptacle 74.3.
    [0222] The V-shaped receiving section forms a defined conveying position for the holding bracket in the area of the meeting lateral flanks.
    The joining elements 180.1, 180.2 according to the third embodiment variant can likewise have an arrangement of connecting openings and oppositely arranged connecting pins for joining the joining elements 180.1, 180.2 in the manner described above.
    7a and 7b show the maximum lateral deflection of the swivel body 71.2 with respect to the connection body 72, which is predetermined by the swivel stop 75 of the connecting body 72 and the swivel limiting surfaces 76 of the swivel body 71.2.
    The swivel body 71.2 can be deflected laterally by half the maximum swivel angle W / 2 from a vertical V in a swivel direction S oriented transversely to the conveying direction F. In the maximum lateral deflection, the swivel body 71.2 hits the swivel stop 75 on the connecting body 72 with a swivel limiting surface 76.
    Of course, the representation according to FIGS. 7a and 7b also applies to the first embodiment variant according to FIG. 3.
