Description

[0001] CONVEYOR MODULE AND MODULAR SUSPENDED CONVEYOR DEVICE

[0002] The invention relates to a conveyor technology module for a modularly constructed overhead conveyor device for transporting hanging goods, comprising a standardized external dimension, a support structure whose dimension is adapted to the standardized external dimension, and a conveyor path along which transport carriers, in particular self-propelled transport carriers, of the overhead conveyor device can be moved.

[0003] Furthermore, the invention relates to a transfer unit for bridging a height difference comprising a first travel level and a second travel level, which are arranged at different heights, and a plurality of conveyor technology modules.

[0004] Furthermore, the invention relates to an overhead conveyor device for an order picking system, which can be constructed in a modular manner and which comprises a plurality of conveyor technology modules and transport carriers, wherein the conveyor technology modules are arranged next to one another and / or one above the other and are connected to one another in order to form the overhead conveyor device.

[0005] Finally, the invention relates to an order picking system for processing order picking orders, comprising a warehouse, at least one order picking station and an overhead conveyor system for transporting hanging goods with transport carriers from the warehouse to at least one order picking station.

[0006] Typically, overhead conveyors for a picking system are installed, tested, and commissioned on-site at the operator's premises, particularly in a building such as a warehouse. For this purpose, the overhead conveyors are designed in advance and are usually permanently attached to the building. Subsequent modification and / or expansion of the overhead conveyor system can only be achieved with considerable effort.

[0007] EP 2 903 917 B1 discloses an overhead conveyor system with portable conveyor modules that can be assembled and disassembled at short notice. The known conveyor modules comprise a support structure and guide rails firmly connected to the support structure, along which the transport carriers can be moved. The conveyor modules can also comprise a ceiling, with the guide rails mounted at a distance from the ceiling via ceiling brackets. A disadvantage of this is that this results in a high overall height for the individual conveyor modules.

[0008] The object of the invention is therefore to provide an improved conveyor technology module of the type mentioned above. In particular, the conveyor technology modules should be able to be implemented in a smaller installation space, preferably with a lower overall height, and / or enable a particularly flexible conveyor path layout.

[0009] Furthermore, it is an object of the invention to provide an improved transfer unit, overhead conveyor device and order picking system of the type mentioned at the beginning.

[0010] The object of the invention is achieved with a conveyor technology module of the type mentioned at the outset, wherein the support structure comprises a driving platform which forms a driving surface, in particular one which can be aligned horizontally downwards, on which the conveyor line is arranged and on which the transport carriers can adhere in a movable manner, or the support structure comprises a rail system, in particular a travel rail and / or a switch, which has a driving surface and which forms the driving line on which the, in particular self-propelled, transport carriers can be moved.

[0011] A particular advantage achieved with the invention is that the conveyor modules can be assembled and commissioned in advance. Transport carriers can also be loaded into the conveyor modules beforehand. Thus, an overhead conveyor system and / or a picking warehouse can be easily constructed by arranging the conveyor modules in a row and / or stacking them one on top of the other.

[0012] Another advantage achieved with the invention is that a particularly low overall height can be achieved, since no suspension from a ceiling is required. The mobile platform can be provided essentially directly below the ceiling or instead of the ceiling. Likewise, the rail system can be provided essentially directly below the ceiling or instead of the ceiling.

[0013] The conveyor modules can be lined up to form an overhead conveyor system. To expand the overhead conveyor system or change the route of a transport path, individual conveyor modules can be flexibly added and / or replaced with other conveyor modules with different conveyor path layouts.

[0014] Furthermore, the conveyor lines can be arranged flexibly and independently of the guide on the travel platform or travel surface, so that essentially any conveyor line layout can be realized with unchanged and low technical effort.

[0015] For the purposes of the invention, a standardized external dimension is understood to mean an external dimension of the conveyor module that can be provided for a plurality of conveyor modules, in particular for a single conveyor module type. The external dimension essentially comprises a base area of ​​the conveyor module, in particular the side lengths of the base area, and a height of the conveyor module.

[0016] In general, the base area can be of any shape, for example, star-shaped, circular, elliptical, or the like. However, the base area is expediently shaped such that several conveyor technology modules can be arranged directly adjacent to one another, essentially without gaps.

[0017] The conveyor system module is preferably designed with a polygonal base area. The base area can be, for example, quadrangular, in particular rectangular, and the (standardized) dimension can include a length and a width of the base area as well as a height of the conveyor system module. Alternatively, the base area can also be triangular or hexagonal, and the (standardized) dimension can include a side length of the base area and a height of the conveyor system module.

[0018] Particularly preferably, the conveyor technology module is parallelepiped-shaped, in particular cuboid-shaped, and comprises a first, second, third and fourth side, wherein the first and second sides as well as the third and fourth sides are opposite one another.

[0019] The transport carriers are designed especially for the hanging transport of hanging goods.

[0020] The hanging goods can be formed, on the one hand, by articles, in particular items of clothing, which are hung from the transport supports by means of coat hangers, and, on the other hand, by transport bags which are hung from the transport supports and are designed to hold articles. It is advantageous if the hanging conveyor device comprises the hanging goods, which can be transported with the transport support, and the hanging goods optionally have a transport bag with a bag body for storing the goods.

[0021] The support structure may comprise one or more travel platforms or one or more rail systems and is preferably designed to be placed on a floor.

[0022] It is advantageous if the travel platform is ferromagnetic at least in some areas, particularly along the conveyor line, so that the transport carriers can adhere to the travel surface by means of magnetic interaction. In this case, the travel platform can comprise a ferromagnetic material, particularly a steel sheet.

[0023] To connect the mobile platform or the rail system to the support structure, it is preferably provided that the support structure has a polygonal frame and uprights arranged in corner regions of the frame, wherein the mobile platform or the rail system is mounted on the frame. The frame is preferably rectangular or hexagonal, in particular honeycomb-shaped. The mobile platform is arranged on the frame. The mobile platform can be attached to the frame, for example by welding or screwing. The rail system can preferably be arranged directly on the frame. The mobile platform can be attached to the frame, for example by welding or screwing.

[0024] Furthermore, uprights can be provided in some of the corner areas, preferably in all corner areas. The uprights can be used to position the conveyor module on a floor, another conveyor module, or the like. The uprights preferably comprise a first end mounted on the frame and a second end facing away from the frame, with the uprights extending, in particular, in a straight line from the first end to the second end. The uprights are preferably aligned parallel to one another.

[0025] Advantageously, the mobile platform has a first mounting surface facing away from the running surface, and the frame has a second mounting surface facing the mobile platform, wherein the first mounting surface and the second mounting surface abut one another. Thus, the mobile platform can be arranged directly on the frame without suspension, allowing the conveyor system module to be designed with a particularly low overall height. The second mounting surface is preferably oriented parallel to the base surface and in the direction of the base surface, in particular downwards.

[0026] In order to form an overhead conveyor device with multiple superimposed travel surfaces or travel levels or rail systems and / or a warehouse with multiple superimposed storage levels, it is preferably provided that the conveyor module is designed to be stackable. The travel levels and / or storage levels can be formed, for example, by travel platforms or rail systems of the conveyor modules.

[0027] In order to fix conveyor technology modules arranged directly adjacent to one another, in particular next to one another and / or one above the other, it is preferably provided that the support structure has a mechanical connection arrangement via which the support structure of the conveyor technology module can be connected, in particular screwed, to the support structure of a further conveyor technology module arranged on the conveyor technology module and / or of a further conveyor technology module arranged next to the conveyor technology module.

[0028] The mechanical connection arrangement preferably comprises a first mechanical connection device, via which the support structure of the conveyor technology module can be mechanically connected to a support structure of a further conveyor technology module arranged, in particular stacked, on the conveyor technology module, and / or a second mechanical connection device, via which the support structure of the conveyor technology module can be connected to a support structure of a further conveyor technology module arranged next to the conveyor technology module, in particular directly adjacent to it.

[0029] The first mechanical connecting device preferably comprises a first mechanical vertical connection element and a second mechanical vertical connection element. The first mechanical vertical connection element of the conveyor module can be mechanically connected, in particular screwed, to the second mechanical vertical connection element of the further conveyor module arranged on the conveyor module. The first mechanical vertical connection element is preferably arranged at the first end of the uprights and / or on the frame, and the second mechanical vertical connection element is arranged at the second end of the uprights. Furthermore, it is preferably provided that the second mechanical connecting device comprises a plurality of mechanical horizontal connection elements.The mechanical horizontal connection elements can each be mechanically connected to a mechanical horizontal connection element of the additional conveyor module arranged next to the conveyor module, in particular directly adjacent to it. The horizontal connection elements are preferably arranged on the travel platform or on the rail system, so that the travel platforms or the rail systems of two directly adjacent conveyor modules can be connected to one another and aligned with one another. Particularly preferably, the travel platform comprises a plurality of circumferential sides delimiting the travel platform, with a mechanical horizontal connection element arranged on each circumferential side, in particular in the region of the conveyor line.

[0030] According to one possible embodiment, the support structure can have a frame and uprights arranged in corner areas of the frame, and the driving platform or the rail system is designed to be adjustable relative to the frame in order to align rail systems of conveyor technology modules arranged directly adjacent to one another in alignment with one another.

[0031] In order to align the driving platforms of conveyor technology modules arranged directly adjacent to one another, it is preferably provided that the driving platform is designed to be height-adjustable.

[0032] This allows for a smooth transition between the running surfaces of adjacent conveyor modules and thus ensures a very smooth running of the transport carrier.

[0033] For height adjustment, the uprights can, for example, have an extendable foot or be designed to be longitudinally adjustable, in particular telescopic. The extendable foot is preferably arranged at the second end of the uprights.

[0034] Alternatively or additionally, the travel platform or the rail system can be mounted on the uprights so that it can be moved, in particular displaced, along the uprights.

[0035] The conveyor module advantageously has several conveyor interfaces, particularly for connecting conveyor lines of directly adjacent conveyor modules for material flow purposes. The conveyor interfaces are connected via the conveyor line. The conveyor line can be of any configuration, for example, curved or straight.

[0036] The conveyor technology interfaces can each form, for example, a conveyor technology input through which transport carriers can be introduced into the conveyor technology module, in particular onto the conveyor line, or a conveyor technology output through which transport carriers can be removed from the conveyor technology module, in particular from the conveyor line. It is expedient if the conveyor technology module has at least one conveyor technology input and at least one conveyor technology output.

[0037] Preferably, the conveyor line runs from a first conveyor interface of the conveyor interfaces to a second conveyor interface of the conveyor interfaces. It is also advantageous if the conveyor line has at least one junction and / or branch connecting the conveyor line to at least one further conveyor interface.

[0038] In the case of an overhead conveyor device, the conveyor technology modules can, for example, preferably be arranged in such a way that the conveyor technology interfaces of directly adjacent conveyor technology modules are adjacent to one another, so that the transport carriers can be transferred from one conveyor technology module to the next via the conveyor technology interfaces.

[0039] It is advantageous if the conveyor interfaces each form a contact surface, with each contact surface being adjustable to a contact surface of a directly adjacent conveyor module. The contact surface is preferably provided by a peripheral side surface of the travel platform. The conveyor sections of two directly adjacent conveyor modules can thus be connected by a butt joint between the two contact surfaces.

[0040] A connection, particularly a butt joint, between two conveyor interfaces can be secured, for example, by the previously described mechanical connection arrangement, particularly by the mechanical horizontal connection unit. In the simplest case, the conveyor interface is an area of ​​the peripheral side surface of the travel platform to which the conveyor line of the conveyor module leads and at which it ends.

[0041] In order to align the conveyor interfaces of two directly adjacent conveyor modules, it can be provided that the conveyor interfaces are mounted on the driving platform so that they can be adjusted along the driving platform and / or orthogonally to the driving platform. In order to align the conveyor interfaces of two directly adjacent conveyor modules, it can be provided that the conveyor interfaces are mounted on the support structure so that they can be adjusted in the direction of a longitudinal extension of the frame and / or orthogonally to the longitudinal extension of the frame.

[0042] It is advantageous if the conveyor technology module has a first side, wherein at least one conveyor technology interface of the conveyor technology interfaces is arranged on the first side.

[0043] For example, one or more conveyor interfaces designed as conveyor inputs can be arranged on the first side. This allows the transport carriers to be introduced onto the conveyor line on the first side.

[0044] In addition, one or more conveyor interfaces designed as conveyor exits can be arranged on the first side. This allows the transport carriers to be removed from the conveyor line on the first side.

[0045] If both the conveyor system input and the conveyor system output are located on the first side, this allows the transport carriers to be inserted onto and removed from the conveyor system on the same side.

[0046] It is advantageous if the conveyor technology module has a second side different from the first side, wherein at least one conveyor technology interface of the conveyor technology interfaces is arranged on the second side.

[0047] For example, one or more conveyor interfaces designed as conveyor inputs can be arranged on the second side. This allows transport carriers to be additionally introduced onto the conveyor line from the second side. Furthermore, one or more conveyor interfaces designed as conveyor outputs can be arranged on the second side. This allows transport carriers to be guided onto the conveyor line on the first side and removed from the conveyor line on the second side.

[0048] Preferably, the second side is arranged opposite the first side. Alternatively, the second side can be arranged adjacent to the first side at an angle, for example, at an angle of 90° or 120°. This allows the conveyor line to be guided around the corner.

[0049] Preferably, the conveyor module has at least one further side different from the first and second sides, in particular a third side and / or fourth side, wherein at least one conveyor interface of the conveyor interfaces is arranged on the second side. Preferably, the at least one further side is arranged adjacent to the first side at an angle, for example, at an angle of 90° or 120°.

[0050] For example, one or more conveyor interfaces designed as conveyor inputs can be arranged on the at least one additional side. This allows transport carriers to be additionally introduced onto the conveyor line from the at least one additional side.

[0051] In addition, one or more conveyor interfaces designed as conveyor system outputs can be arranged on the at least one additional side. Thus, transport carriers can be guided onto the conveyor line on the first side and removed from the conveyor line on the at least one additional side.

[0052] In order to provide multiple paths for the transport carrier or multiple transport carriers on the conveyor system module, it is preferably provided that the conveyor line has a first conveyor line connecting at least two conveyor interfaces of the conveyor interfaces, and a second conveyor line connecting at least two further conveyor interfaces of the conveyor interfaces. It is advantageous if the first conveyor line and the second conveyor line are connected to one another so that transport carriers can be transferred from the first conveyor line to the second conveyor line.

[0053] Furthermore, it is advantageous if the conveyor line includes a recirculation section. This allows the conveyor line to be easily extended on the conveyor module. The transport carriers can be moved along the recirculation section, allowing the recirculation section to provide, for example, a buffer space or storage area.

[0054] It is expedient if the circulation route is connected to the at least one conveyor technology interface in order to introduce transport carriers into the circulation route or remove them from it. The circulation route preferably comprises an inlet connected to a first conveyor technology interface, in particular to a conveyor technology input, and a branch connected to another conveyor technology interface, in particular to a conveyor technology output. This allows the transport carriers to enter the circulation route via the inlet and to exit the circulation route via the branch.

[0055] The circulation path can also be used to implement a sequencing device, since the transport carriers can enter the circulation path in a first sequence and exit it in a second sequence that is different from the first sequence.

[0056] It is advantageous if the conveyor line is formed by a path marking arranged on the running surface, in particular one that is optically detectable. The path marking can be formed, for example, by a line applied to the running surface, which in particular has a different brightness and / or color than the running surface. Thus, the conveyor line can be implemented particularly easily and without great technical effort. This enables any desired route layout, in particular circular routes and the like, which would require particularly high technical effort with conventional overhead conveyor systems and would therefore not be feasible within a conveyor technology module.

[0057] Alternatively, the line can also be designed as a magnetic strip, which can be detected by a magnetic sensor of the transport carrier, in particular by means of a Hall sensor. The line preferably comprises a first edge and a second edge. When the transport carrier moves, in particular the first edge or the second edge is selectively tracked by the transport carrier. The (optical) route marking can thus be designed as a guide line on the travel surface of the support structure, along which the transport carrier is to travel. In order to form branches of the conveyor line, the conveyor line, in particular the line, can be branched, for example in a star or Y shape, to form junctions and / or branches.

[0058] To navigate the transport carrier to a destination within an overhead conveyor, a path definition can be specified, which essentially specifies a route for the transport carrier to a specified destination. For this purpose, the path definition can, for example, specify a route to be selected for a certain number of junctions, i.e., whether a "straight-ahead" or a "detour" should be performed. For the purposes of the invention, "straight-ahead" is understood to mean continuing the route, and "detour" is understood to mean turning onto a junction or another route.

[0059] It is also advantageous if at least one control marking, particularly visually detectable by the transport carrier, is arranged on the running surface along the conveyor line. The control marking can be used, for example, to mark a new area, a speed limit, a stopping point, a junction, a junction point of several conveyor lines, and / or the like, and to communicate this to the transport carrier. The control markings thus function similarly to traffic control signs.

[0060] The control marking may comprise a signaling marking that marks a signaling point at which the transport carrier is to transmit, in particular, emit, an arrival signal that can be received by a communication unit described below. Such a signaling point may, for example, be located downstream of a junction in the direction of transport or upstream of a junction in the direction of transport.

[0061] Furthermore, the control marking can comprise a query marking, which, for example, marks a branch of the conveyor line and is preferably arranged upstream of the branch in a transport direction. Upon detection of the branch by the transport carrier, the latter should, for example, retrieve a path definition from a memory that indicates which path the transport carrier should take at the branch.

[0062] Furthermore, the control marking can comprise a stop marking, which, for example, marks a stop point at which the transport carrier is to stop. The stop point can be located, in particular, along a circulation route, if this route forms a storage area, for example. Likewise, the stop point can be located upstream of a junction, so that a transport carrier stops at a junction point where conveyor lines converge to avoid a collision with another transport carrier.

[0063] It is expedient if the outer dimension defines an (imaginary) base area, particularly one that can be aligned horizontally. The base area is preferably spanned by the sides of the outer dimension, in particular by a width and length of the outer dimension. This essentially refers to a base area in the geometric sense. This means that it does not necessarily have to be a physical surface, although a (material) base area can be provided by an optional floor of the conveyor module.

[0064] In order to move transport carriers, for example, in a horizontal plane, it is preferably provided that the driving platform of the support structure or the rail system is aligned parallel to the base surface, in particular horizontally, in particular in some areas.

[0065] Furthermore, it can be provided that the driving platform or the rail system, in particular in some areas, is inclined relative to the base area, in particular relative to a horizontal plane.

[0066] It is particularly preferred that the driving platform or the rail system is inclined relative to the base surface in such a way that it forms a driving surface that is inclined, preferably rising or falling, between two conveyor technology interfaces, in particular between a conveyor technology input and a conveyor technology output, or that it forms a rail system that is inclined, preferably rising or falling, between two conveyor technology interfaces, in particular between a conveyor technology input and a conveyor technology output.

[0067] Furthermore, the conveyor system module can be provided with a plurality of travel platforms, one of which is aligned parallel to the base surface and one of which is inclined relative to the base surface. The conveyor system module can also have a plurality of rail systems, one of which is aligned parallel to the base surface and one of which is inclined relative to the base surface.

[0068] It is also conceivable for the platform to have a bend that divides it into a first and a second section. The first section can be parallel to the base surface, and the second section can be inclined relative to the base surface.

[0069] Advantageously, the conveyor technology module comprises an electrical power supply system arranged on the support structure. This allows the transport carriers and, if applicable, a communication unit described below to be supplied with electrical power.

[0070] It is useful if the power supply system can be connected to an (external) power grid. For this purpose, the power supply system can have one or more power supplies.

[0071] It is advantageous if the electrical energy supply system for supplying the transport carriers with electrical energy has at least one electrical line, in particular one that can be contacted by the transport carriers, which runs along the conveyor line. The electrical line preferably comprises exposed electrical conductors, which are designed in particular as contact conductors.

[0072] Advantageously, the transport carriers each have current collectors that are in electrical contact with the electrical conductors. The current collectors can be designed, for example, as sliding contacts, and slide and / or rub against the electrical conductors as the transport carrier moves. Alternatively, the current collectors can also be designed as rolling contacts, for example, as wheels, which rest on the electrical conductors in a rolling manner.

[0073] If the conveyor system module comprises multiple conveyor lines, in particular the first and second conveyor lines, it can be provided that an electrical line is provided for each conveyor line, which can be supplied with electrical power independently of one another. This ensures that the remaining lines, and thus the remaining conveyor lines of a conveyor system module, are supplied with power if, for example, one of the lines fails.

[0074] Furthermore, the electrical power supply system can be provided with an electrical connection arrangement via which the electrical power supply system can be electrically connected to the electrical power supply system of a further conveyor module arranged on the conveyor module and / or of a further conveyor module arranged next to the conveyor module. Thus, the power supply systems of conveyor modules arranged directly adjacent to and / or one above the other can be electrically connected to one another.

[0075] The electrical connection arrangement preferably comprises a first electrical connection device, via which the support structure of the conveyor technology module can be mechanically connected to a support structure of a further conveyor technology module arranged, in particular stacked, on the conveyor technology module, and / or a second electrical connection device, via which the support structure of the conveyor technology module can be connected to a support structure of a further conveyor technology module arranged next to the conveyor technology module, in particular adjacent to it.

[0076] Preferably, the first electrical connection device comprises a first electrical vertical connection unit and a second electrical vertical connection unit, wherein the first electrical vertical connection unit is electrically connectable to the second electrical vertical connection unit of the further conveyor technology module.

[0077] In order to transmit data to the conveyor module and / or to the transport carriers, the conveyor module can comprise a data transmission system arranged on the support structure. The data transmission system is preferably connected to a higher-level computer system, in particular to a master computer. The data connection can be implemented, for example, using a data cable.

[0078] In order to transmit data to all conveyor modules in an overhead conveyor system comprising multiple conveyor modules, the data transmission system can be provided with a data connection arrangement via which the data transmission system can be connected to the data transmission system of another conveyor module arranged on the conveyor module and / or another conveyor module arranged next to the conveyor module. This also allows the overhead conveyor system to be easily expanded, since an additional conveyor module only needs to be connected to an adjacent conveyor module.

[0079] In addition, at least one cable guide can be provided in each of the uprights of the supporting structure, in which a power cable of the electrical energy supply system and / or a data cable of the data transmission system can be guided.

[0080] Preferably, the data transmission system comprises a communication unit configured to receive an arrival signal transmitted by a transport carrier and / or to transmit, in particular to send, a route definition for a transport carrier. The communication unit is preferably designed for wireless, in particular radio-based, data transmission.

[0081] Particularly preferably, the transport carriers each comprise a communication module, which is preferably designed for wireless, in particular radio-based, data transmission. The communication module can, for example, be configured to transmit an arrival signal, in particular in response to the detection of a signal marker, and / or to receive a route definition sent by the communication unit.

[0082] It is also expedient for the conveyor module to have a sprinkler system with at least one water line arranged on the support structure. Firefighting water can be supplied to the conveyor module via the water line.

[0083] Preferably, a plurality of sprinkler nozzles are connected to the water line, through which supplied water can be discharged. The sprinkler nozzles are preferably arranged protruding from the running surface, in particular below the running surface or the rail system, so that the extinguishing water can be distributed throughout the entire conveyor system module.

[0084] Advantageously, the frame is provided with a receptacle for the water line. It is advantageous if the water line comprises a first and second connector piece for connecting, in particular pluggable, water lines of two adjacent conveyor technology modules.

[0085] Furthermore, it is advantageous if the at least one water line is arranged on a side of the travel platform facing away from the running surface, and the travel platform has at least one recess for a water passage. Arranging the water line substantially above the travel platform ensures that the movement of the transport carrier is not hindered or restricted by the water line. The water passage allows the extinguishing water to be directed through the travel platform into an interior of the conveyor module.

[0086] In particular, it is provided that the sprinkler nozzles are arranged on the side of the driving platform where the driving surface is located. The sprinkler nozzles can each be connected to the water line via a connecting line, with the connecting line being routed through the recess.

[0087] It is expedient if the conveyor technology module comprises a self-propelled, preferably several self-propelled, transport carriers.

[0088] A possible design of a (non-rail-based) transport carrier is described in detail, for example, in the Austrian patent application with the file number A50463 / 2022 or WO 2023 / 147620 A1, which is incorporated in its entirety into this application and thus made the subject of this application. A possible design of a (rail-based) transport carrier is described in detail, for example, in WO 2019 / 234046 A1 or WO 2023 / 147619 A1, which is incorporated in its entirety into this application and thus made the subject of this application.

[0089] In order to move the (non-rail-bound) transport carrier along the travel routes, it is preferably provided that the transport carrier comprises a detection unit, in particular an optical one, which is designed to detect the running surface, in particular a marking arranged on the running surface. The detection unit can, in particular, detect the track marking and / or the control marking. It is advantageous if the detection unit comprises a track surface sensor, which is selected from a group comprising an optical sensor, a mechanical sensor, an electronic sensor and / or a magnetic field sensor. It is expedient if the track marking is designed accordingly. The track marking can influence the movement of the transport carrier.In particular, the driving surface sensor can be designed as an optical driving surface sensor and the driving path marking as an optical driving marking and / or the control marking as an optical control marking.

[0090] Furthermore, it is advantageous if the transport carrier comprises a drive device and a drive control which is designed to control the at least one drive device in such a way that the transport carrier follows the conveyor line.

[0091] The drive device is preferably designed to convert a provided, in particular electrical, drive energy into kinetic energy for transporting the hanging goods.

[0092] Furthermore, the drive control is preferably designed to control the drive device according to the path definition.

[0093] The transport carrier advantageously includes a writable and readable memory. The previously described communication module can, for example, be configured to store a received route definition in the memory.

[0094] Furthermore, the driving control can be configured to retrieve a path definition stored in the memory, in particular in response to detection of a query marking by the detection unit of the transport carrier.

[0095] In order to move transport carriers along a curved travel path, it is preferably provided that the drive device has at least two drive wheels, in particular at least one first drive wheel and at least one second drive wheel, which are arranged on opposite sides of the transport carrier and which bear against the travel surface, and comprises at least one electrically operated motor arranged on the transport carrier, wherein the drive wheels are coupled to the at least one electrically operated motor, so that they, in particular the at least one first drive wheel and the at least one second drive wheel, can be driven at different speeds and / or different drive torques from one another.

[0096] Preferably, the (non-rail-bound) transport carrier comprises a, in particular magnetic, adhesive force generator. The adhesive force generator allows the transport carrier to adhere to the running surface. Particularly preferably, the adhesive force generator comprises one or more permanent magnets for this purpose.

[0097] The further object is achieved by utilizing the advantages and effects described above with a transfer unit of the type mentioned at the outset, wherein a first conveyor module and a second conveyor module of the conveyor modules are designed as described above and the driving platform of the support structure is aligned, in particular in regions, parallel to the base area, in particular horizontally, wherein the driving platform of the first conveyor module is arranged in the first driving plane and the driving platform of the second conveyor module is arranged in the second driving plane, and a third conveyor module of the conveyor modules is designed as described above and the driving platform is arranged, in particular in regions, inclined relative to the base area, in particular relative to a horizontal plane,wherein the travel platform of the third conveyor module extends from the first travel level to the second travel level and connects to the travel platforms of the first and second conveyor module.

[0098] A particular advantage of the transfer unit is its modular design, allowing stacked travel levels to be connected. The transfer unit can easily be expanded to include any number of additional travel levels by adding additional conveyor modules.

[0099] The first and second conveyor technology modules are preferably arranged parallel to each other.

[0100] It is particularly preferably provided that the transfer unit has a third travel level and a fourth conveyor technology module of the conveyor technology modules is designed as described above and the travel platform, in particular in some areas, is inclined relative to the base area, in particular relative to a horizontal plane, wherein the travel platform of the fourth conveyor technology module runs from the second travel level to the third travel level and connects to the travel platform of the second conveyor technology module.

[0101] It is advantageous if the third and fourth conveyor technology modules are arranged parallel to each other.

[0102] Advantageously, the transfer device comprises a travel path extending helically around a vertical axis, which is composed of the travel paths of the conveyor modules. The travel path comprises one or more stacked turns, with the turns each being formed by the first, second, third, and fourth conveyor modules.

[0103] The further object is further achieved by utilizing the advantages and effects described above by a suspended conveyor device of the type mentioned at the outset, wherein at least some of the conveyor technology modules are constructed according to one of the aspects described above and are arranged such that the conveyor paths of the conveyor technology modules form a transport path along which the transport carriers are movable.

[0104] An advantage achieved with the invention is in particular that a modularly constructed overhead conveyor device is created which can be easily expanded by adding further conveyor technology modules.

[0105] In particular, it can be provided that some of the conveyor technology modules are constructed identically and may only differ in a conveyor route or an arrangement of the conveyor technology interfaces.

[0106] If the overhead conveyor device has a plurality of conveyor technology modules arranged one above the other, it is preferably provided that the overhead conveyor device has a transfer unit according to one of the aspects described above and a plurality of storage levels arranged one above the other, which are each formed by travel platforms of conveyor technology modules, wherein a first storage level of the storage levels is arranged in a plane with the first travel level of the transfer unit and a second storage level is arranged in a plane with the second travel level of the transfer unit, and the storage levels are connected via the transfer unit for material flow purposes. Advantageously, it is provided that some of the conveyor technology modules are designed as described above and that the conveyor path of some of the conveyor technology modules each has a circulation path. As a result, the conveyor technology modules can each form, for example, a storage location, a buffer location or a sequencing device.

[0107] In order to form a warehouse for storing hanging goods, it can be provided that some of the conveyor technology modules are designed according to one of the aspects described above, wherein the several conveyor technology modules each have conveyor technology interfaces which are arranged on the first and / or second side of the conveyor technology module and are arranged one behind the other in one plane and form a warehouse travel area.

[0108] Furthermore, it is preferably provided that some of the conveyor technology modules have a circulation path and are arranged in one plane one behind the other and next to the conveyor technology modules of the storage travel area, and form storage locations arranged along the storage travel area.

[0109] In this case, conveyor lines of conveyor technology modules arranged one behind the other and next to each other can be connected to each other via the respective conveyor technology interfaces.

[0110] The transport carriers can be moved to or from the storage locations via the conveyor lines of the storage area. The transport carriers can be stored or temporarily stored on the conveyor lines of the storage locations.

[0111] To achieve increased storage capacity, the storage travel area and the storage locations can be arranged to form a storage row, with the overhead conveyor device comprising a plurality of adjacent storage rows forming a storage level. It is advantageous to provide several storage levels arranged one above the other.

[0112] For example, in order to transmit route definitions to the transport carriers, receive arrival signals from the transport carriers, or otherwise communicate with the transport carriers and / or transmit data to them, it is preferably provided that at least some of the conveyor technology modules have a communication unit as described above, and the overhead conveyor device comprises a master computer that is (data-related) connected to the communication unit of the respective conveyor technology modules. The master computer can be connected to the communication units, for example, via a data cable.

[0113] It is advantageous if the overhead conveyor system includes a data transmission network, with the data transmission systems of the conveyor modules each being connectable to the data transmission network of the overhead conveyor system. The master computer can also be connected to the data transmission network and, via this, to the communication units.

[0114] The master computer is preferably configured to specify a destination along the transport route for each transport carrier, for example, a storage location, and to create a route definition that defines the transport carrier's route to the destination. For this purpose, the route definition can, for example, specify for each junction which conveyor line the transport carrier should follow. The route definition can be transmitted to the transport carriers via the communication unit, as described above.

[0115] In order to transmit different route definitions to different transport carriers, the master computer is particularly preferably configured to select a transport carrier of the transport carriers, define a destination along the transport route for the selected transport carrier, create a route definition which specifies a route from a current position of the selected transport carrier to the defined destination, and transmit the route definition to the selected transport carrier via the communication unit.

[0116] The conveyor technology modules can be designed with a particularly low overall height. In particular, such that there is just enough space for hanging goods. The overall height can therefore be significantly less than the height of an operator. In order to still ensure ergonomic access for an operator to the overhead conveyor device, for example for maintenance purposes, it is preferably provided that the overhead conveyor device has a plurality of service modules which comprise a standardized external dimension and a support structure whose dimensions are adapted to the standardized external dimension, wherein the support structure comprises at least one walkable platform, wherein the overall height of the service modules is preferably at least twice as high as the overall height of the conveyor technology modules. Thus, essentially at least two storage levels or two travel levels can be reached and serviced via one service module.In order to supply the conveyor technology modules with electrical energy, it is preferably provided that at least some of the conveyor technology modules, in particular all conveyor technology modules, are designed according to one of the aspects described above and have an energy supply system, and the overhead conveyor device comprises an energy supply network, wherein the energy supply systems of the conveyor technology modules are each electrically connectable to the energy supply network of the overhead conveyor device.

[0117] Furthermore, it is preferably provided that some of the conveyor modules have a first standardized external dimension and some of the conveyor modules have a second standardized external dimension. This allows the overhead conveyor device to be designed to be particularly flexible.

[0118] The further object is further achieved by utilizing the advantages and effects described above with an order picking system of the type mentioned at the outset, wherein the overhead conveyor technology comprises an overhead conveyor device according to one of the aspects described above.

[0119] The picking system for processing picking orders can comprise an order management system for electronically recording picking orders, a warehouse, at least one picking station, and a modular overhead conveyor system. The order management system can be connected (for data purposes) to a master computer, which in turn controls the transport carriers, which are in particular self-propelled and preferably individually controllable. In particular, the master computer transmits route information (for data purposes) to the transport carriers so that the transport carriers can be moved in a controlled manner along the transport routes described below in the transport modules, storage modules, and / or sorting modules. The picking system can thus also comprise a master computer for controlling the transport carriers.

[0120] The overhead conveyor system is used i) to transport hanging goods using (rail-mounted or non-rail-mounted) transport carriers from the warehouse to at least one picking station, and ii) to store, transport, and, if necessary, sort hanging goods using transport carriers in the warehouse, and iii) to sort hanging goods using transport carriers during the transport movement from the warehouse to at least one picking station. For this purpose, the picking system comprises a multitude of functionally different conveyor modules. The conveyor modules are arranged side by side and / or one above the other and interconnected.

[0121] Some of the conveyor technology modules form transport modules. The transport modules are constructed and arranged in such a way that the travel paths of the conveyor technology modules (transport modules) form a transport path along which the transport carriers can be moved. The transport modules are arranged side by side and / or one above the other and are interconnected.

[0122] Some of the conveyor technology modules form storage modules of the warehouse. The storage modules are constructed and arranged in such a way that the travel routes of the conveyor technology modules (storage modules) form a transport path along which storage sections are arranged, in which the transport carriers can be stored, and along which the transport carriers can be moved and, if necessary, sorted when they are needed to process picking orders. The storage sections are primarily used for longer-term storage of the transport carriers in one or more storage modules, for example, several hours or days. A storage section is therefore not the same as a buffer section, in which transport carriers are only buffered or accumulated for a short period of time, for example, a few seconds or minutes. In particular, the warehouse corresponds to a supply warehouse, where hanging goods or hanging goods are stored using transport carriers.

[0123] Some of the conveyor technology modules form sorting modules. The sorting modules are constructed and arranged such that the travel paths of the conveyor technology modules (sorting modules) form a transport path along which sorting sections are arranged, in which the transport carriers can be sorted for processing picking orders, and along which the transport carriers can be moved when they are needed to process picking orders at the picking station in a sequence. The sorting modules are located upstream of at least one picking station. In particular, the sorting modules are arranged between the warehouse and the at least one picking station.

[0124] According to a first embodiment, some of the transport modules and storage modules are arranged next to each other and / or one above the other and connected to each other so that the travel paths of the transport modules and storage modules merge and the transport carriers are movable between the transport modules and storage modules.

[0125] According to a second embodiment, some of the transport modules and sorting modules are arranged next to each other and / or one above the other and are connected to each other so that the travel paths of the transport modules and sorting modules merge and the transport carriers are movable between the transport modules and sorting modules.

[0126] According to a third embodiment, some of the storage modules and sorting modules are arranged next to each other and / or one above the other and are connected to each other so that the travel paths of the storage modules and sorting modules merge and the transport carriers are movable between the storage modules and sorting modules.

[0127] On the one hand, it may prove advantageous if the first embodiment and second embodiment are combined, and on the other hand, it may prove advantageous if the first embodiment and third embodiment are combined.

[0128] However, it can also be advantageous to combine the first version, second version and third version.

[0129] The picking station can be configured for manual and / or automated picking of hanging goods according to a picking order. At the picking station, hanging goods can be provided suspended from the transport supports by the overhead conveyor system. Target containers, into which the hanging goods are to be transferred according to picking orders, can also be provided at the picking station, for example, using a floor-based conveyor system.

[0130] It is advantageous if some of the conveyor modules of the overhead conveyor system form the warehouse. For this purpose, the conveyor modules can form storage locations and a warehouse travel area, as described above.

[0131] For a better understanding of the invention, it is explained in more detail using the following figures.

By way of introduction, it should be noted that in the variously described embodiments, identical parts are provided with identical reference symbols or component designations, whereby the disclosures contained throughout the description can be applied mutatis mutandis to identical parts with identical reference symbols or component designations. Furthermore, the positional information chosen in the description, such as top, bottom, side, etc., refers to the directly described and illustrated figure and, in the event of a change in position, is to be applied mutatis mutandis to the new position.

[0150] Fig. 1 and Fig. 2 show a perspective view of a conveyor module 1 for an overhead conveyor device 22, viewed obliquely from below and obliquely from above, respectively. The conveyor module 1 has standardized external dimensions L, W, H. Preferably, the conveyor module 1 is designed with a rectangular base and is cuboid-shaped, so that the external dimensions are defined by a length L, a width B, and a height H of the conveyor module 1.

[0151] The conveyor technology module 1 preferably comprises a first side S1, a second side S2, and further sides S3, S4. The first side S1 and the second side S2 are arranged opposite one another and parallel to one another. Furthermore, the further sides S3, S4 comprise a third side S3 and a fourth side S4, which are also arranged opposite one another and parallel to one another.

[0152] The conveyor system module 1 comprises a support structure 2a, 2b, 2c with a traveling platform 2a and, optionally, several supports 2b and / or a frame 2c. The traveling platform 2a is preferably attached to the supports 2b, in particular via the frame 2c. To ensure stability, the supports 2b can be arranged in corner areas, in particular in corners, of the frame 2c.

[0153] Fig. 3 shows a side view of the driving platform 2a and the frame 2c. The driving platform 2a has a first mounting surface M1, and the frame 2c has a second mounting surface M2, which face and are aligned with each other. The first mounting surface M1 and the second mounting surface M2 are adjacent to each other.

[0154] The moving platform 2a forms, particularly on its underside, a running surface T to which transport carriers 3 can be movably attached, preferably via magnetic interaction. For the purposes of the invention, the underside is understood to be a side of the moving platform 2a facing the base surface. The transport carrier 3 is designed for transporting hanging goods W, as can be seen in Fig. 1.

[0155] A track 4 is arranged on the running surface T, along which transport carriers 3 can be moved. The track 4 can be marked by a track marking U, in particular an optically detectable one.

[0156] The driving platform 2a can be aligned parallel to the base surface, as shown in Fig. 1 and Fig. 2, or inclined relative to the base surface, as shown in Fig. 4a, for example. All other features can be provided independently of the orientation of the driving platform 2a.

[0157] The conveyor technology module 1 shown comprises two conveyor technology interfaces 7, one of which is designed as a conveyor technology input and one of which is designed as a conveyor technology output. The transport carrier 3 can be inserted into the conveyor technology module 1 via the conveyor technology input and removed from it via the conveyor technology output. The conveyor technology interfaces 7 are connected to one another via the travel path 4. Conveniently, one transport direction runs from the conveyor technology input to the conveyor technology output.

[0158] By placing two conveyor technology modules 1 next to each other so that the conveyor technology interfaces 7 are connected to each other, two conveyor technology modules 1 can be connected in terms of material flow and, if necessary, a suspended conveyor device 22 can be formed.

[0159] The travel route 4 can be essentially U-shaped, as shown by way of example in Fig. 1, and the conveyor technology interfaces 7 can be arranged on the same side of the conveyor technology module. In the example shown in Fig. 3, the travel route 4 is rectilinear and runs between two opposite sides. The arrangement of the conveyor technology interfaces 7 is not operatively related to other features of the conveyor technology module 1, so that the further described features can be provided independently of the arrangement of the conveyor technology interfaces 7 and / or a travel route. Various travel route profiles that can be implemented with the conveyor technology module 1 are described below with reference to Fig. 6a to Fig. 6h. The travel platform 2a is expediently designed to be height-adjustable. For this purpose, the uprights 2b can have extendable feet at an end of the uprights 2b facing away from the travel platform 2a.Alternatively, the driving platform 2a can be mounted on the uprights 2b so that it can move along them, in particular in the vertical direction.

[0160] The conveyor technology module 1 can have an optional mechanical connection arrangement 8a..8d, via which conveyor technology modules 1 arranged one above the other and / or next to one another can be connected to one another.

[0161] The mechanical connection arrangement 8a..8d comprises a first mechanical connection device for connecting conveyor technology modules 1 arranged one above the other.

[0162] The first mechanical connecting device comprises a plurality of first vertical connecting elements 8a, which are arranged on the frame 2c and / or on an upper end of the uprights 2b, and a plurality of second vertical connecting elements 8b, which are arranged on a lower end of the uprights 2b.

[0163] Furthermore, the mechanical connection arrangement 8a..8d can comprise a second mechanical connection device for connecting conveyor technology modules 1 arranged next to one another. The second mechanical connection device comprises a plurality of first horizontal connection elements 8c and a plurality of second horizontal connection elements 8d, each of which is arranged on the travel platform 2a.

[0164] The mechanical connection arrangement 8a..8d is not explicitly shown in Fig. 2 to Fig. 4a, 4b.

[0165] In addition, the conveyor technology module 1 preferably comprises an energy supply system 38, which is described in more detail below.

[0166] Optionally, the power supply system 38 can have an electrical connection arrangement 9a..9c, via which the electrical power supply system 38 can be electrically connected to the electrical power supply system 38 of a conveyor system arranged on the conveyor system module 1 and / or adjacent to the conveyor system module 1. For this purpose, the electrical connection arrangement 9a..9c comprises electrical vertical connection elements 9a and electrical horizontal connection elements 9b, which can be arranged, for example, on the upright 2b and / or on the travel platform 2a. The electrical vertical connection elements 9a and / or the electrical horizontal connection elements 9b can be designed, for example, to establish a plug connection.

[0167] In addition, the electrical energy supply system 38, in particular the electrical connection arrangement 9a..9c, can have an optional power supply unit 9c, via which the conveyor technology module 1 can be connected to an external power supply system.

[0168] Furthermore, the data transmission system can have a data connection arrangement 10a, 10b, via which the data transmission system can be connected to the data transmission system of another conveyor module 1 arranged on the conveyor module 1 and / or next to the conveyor module 1. For this purpose, the data connection arrangement 10a, 10b comprises data horizontal connection elements 10b and data vertical connection elements 10a, which can be arranged, for example, on the upright 2b and / or on the travel platform 2a. The data vertical connection elements 10a and / or the data horizontal connection elements 10b can be designed, for example, to establish a plug-in connection.

[0169] For transmitting data to the transport carrier 3, in particular for communicating with the transport carrier 3, the conveyor technology module 1, in particular the data transmission system, can have a communication unit 11. The communication unit 11 can be mounted on the support structure 2a, 2b, 2c, as shown in Fig. 2.

[0170] By means of the communication unit 11, for example, a route information or route definition previously created, in particular by a time computer 23, can be transmitted to the transport carrier 3, which indicates a route for the transport carrier 3 up to a specified destination.

[0171] The conveyor system module 1 can have an optional sprinkler system, which includes at least one water line 12 through which extinguishing water can be supplied. The water line 12 can be arranged on the support structure 2a, 2b, 2c. In particular, the frame 2c has a receptacle for the water line 12, as can be seen in Fig. 2.

[0172] In addition, the driving platform 2a can have a recess 13 or several recesses 13 for a water passage through which water can pass or through which water can be passed by means of further water pipes 12 and / or sprinkler nozzles not explicitly shown.

[0173] The water line 12 preferably has a first and a second connecting piece, which is designed to produce a plug-in connection between water lines 12 of two conveyor technology modules 1 arranged next to one another.

[0174] Fig. 5 shows two conveyor modules 1 stacked one above the other. As can be seen, the stacked conveyor modules 1 are connected via the mechanical connection arrangement, in particular via the first vertical connection element 8a and the second vertical connection element 8b. The travel surfaces T of the conveyor modules 1 are arranged on different travel levels FE.

[0175] In Fig. 6a to Fig. 6h, conveyor technology modules 1 with different route layouts are shown schematically.

[0176] For example, Fig. 6a shows the course of the travel route 4 known from Fig. 1. Here, the conveyor interfaces 7 are arranged on the same side, namely on the third side S3. Of course, a route rotated by 90° is also possible, in particular, in which the conveyor interfaces 7 are arranged on the first side S1.

[0177] Furthermore, Fig. 6b to Fig. 6d show a possible conveyor system module 1, which has two conveyor system interfaces 7 arranged on opposite sides of the conveyor system module 1, in particular on the first side S1 and the second side S2. The conveyor system interfaces 7 are connected for material flow via the travel path 4. The travel path 4 does not necessarily have to run in a straight line, but can also follow a curved trajectory and, for example, be S-shaped.

[0178] For example, one or more further optional conveyor technology interfaces 7 can be provided, which form a conveyor technology output and are connected to the travel route 4 via a branch 14 shown in dashed lines. Likewise, one or more further optional conveyor technology interfaces 7 can be provided, which form a conveyor technology input and are connected to the travel route 4 via a junction 15 shown in dashed lines. Transport carriers 3 can branch off from the travel route 4 via the branch 14 and, for example, be led to an adjacent conveyor technology module 1. Likewise, transport carriers 3 can be transferred to the travel route 4 via junctions 15, for example coming from an adjacent conveyor technology module 1.

[0179] The optional conveyor technology interfaces 7 can be arranged, for example, as shown in Fig. 6b on the same side, in particular on the third side S3, or as shown in Fig. 6c and Fig. 6d on opposite sides, in particular on the third side S3 and fourth side S4.

[0180] It can also be provided that the courses of the travel route 4 shown in Fig. 6b to Fig. 6d are rotated by 90°, so that the travel route 4 runs from a conveyor technology interface 7 on the third side S3 to a conveyor technology interface 7 on the fourth side S4 and the branches 14 and / or junctions 15 are connected to conveyor technology interfaces 7 on the first side S1 and / or second side S2.

[0181] Furthermore, it can be provided that the travel path 4 comprises two travel paths, which, for example, run parallel to each other, as shown in Fig. 6e and Fig. 6f. The conveyor system module can comprise four conveyor system interfaces 7, which are connected in pairs via a travel path 4 each.

[0182] In addition, as previously described in connection with Fig. 6b to Fig. 6d, several optional further conveyor technology interfaces 7 can be provided, which are connected to the first travel route 4 and / or the second travel route 4 via optional junctions 15 and / or branches 14.

[0183] As shown in Fig. 6f, the two travel paths 4 can be connected to each other via a short-circuit path 16 shown in dashed lines.

[0184] Furthermore, the route 4 can have a circular route 17, which is connected to conveyor technology interfaces 7, for example via a junction 15 and / or a branch 14. The conveyor technology interfaces 7 can be arranged on the same side of the conveyor technology module 1, for example on the third side S3, as in Fig. 6g, or on different sides of the conveyor technology module 1, for example on the second side S2, as in Fig. 6h. The examples shown in Figs. 6a to 6h do not show all possible route layouts, but merely represent a few examples. In the examples shown, the conveyor technology module 1 is designed with a rectangular base area, wherein the first side S1 and second side S2 are each shorter than the third side S3 and fourth side S4.Alternatively, however, the first side S1 and the second side S2 can each be longer or of the same length as the third side S3 and fourth side S4. It is also conceivable for the conveyor module 1 to be designed with a hexagonal base.

[0185] Fig. 7 shows an example of a route, wherein the route 4, as in the previously shown examples, is defined in particular by the route marking U. The route marking U is formed by an optically detectable line with two edges running parallel to each other.

[0186] To follow the route 4, the transport carrier 3 can be configured to detect the route marking U and optionally follow, in particular according to the path definition, a left edge or right edge in the transport direction R. For example, the path definition specifies whether the left or right edge should be followed. The transport direction R is indicated by an arrow in Fig. 7.

[0187] A plurality of control markings detectable by the transport carrier 3, in particular optically, can be arranged along the route 4, which prescribe an action to the transport carrier 3. For example, the control markings include a query marking VI, a notification marking V2, and / or a stop marking V3.

[0188] The query marking VI is preferably arranged in the region of a junction 14, in particular upstream of the junction 14 in the transport direction R. As a result of the query marking V 1 being detected by the transport carrier 3, the latter can retrieve the path definition.

[0189] If the path definition for junction 14 specifies, for example, "right edge" or "1", this can mean that the right edge of the route marking U in the transport direction R should be followed, which in the example shown corresponds to a further course of route 4 or a "straight ahead". Alternatively, the path definition for junction 14 can also specify "left edge" or "0". This can mean, for example, that the left edge of the route marking U in the transport direction R should be followed, which in the example shown corresponds to a course of junction 14 or a "detour".

[0190] The signaling marker V2 is preferably arranged in the region of a junction 15, in particular upstream of the junction 15 in the transport direction R. The transport carriers 3 are preferably designed to transmit an arrival signal in response to detection of the signaling marker V2, which can be received by the communication unit 11. In response to receiving the arrival signal, the communication unit 11 can, for example, transmit a route definition.

[0191] Stopping points can be provided along the route 4, at which the transport carriers 3 are to stop. Such stopping points can be arranged, for example, in the region of a junction 15 or intersection of routes 4 or at storage locations 102. The stopping points can each be marked by a stopping marker V3. Preferably, the transport carriers 3 are designed to decelerate and / or stop in response to the detection of the stopping marker V3. The stopping marker V3 can be a separate marker, as shown in Fig. 7, or it can be provided by the signaling marker V2.

[0192] Essentially, the query marking VI, the notification marking V2, and / or the stop marking V3 can be designed in any desired manner, for example, as a rectangle, circle, triangle, barcode, QR code, or the like. It is expedient for the query marking VI, the notification marking V2, and / or the stop marking V3 to be distinguishable from one another.

[0193] In Fig. 8, a transfer unit 20 for bridging a height difference between travel levels FE arranged at different height levels is shown in a schematic bottom view and in Fig. 9 in a perspective view.

[0194] The transfer unit 20 comprises a plurality of conveyor modules 1 with a horizontal running surface T, as shown in Fig. 1, each forming a horizontal section 21a. In addition, the transfer unit 20 comprises a plurality of conveyor modules 1 with an inclined running surface T, as shown in Fig. 4a, each forming a rising section 21b. As can be seen in particular in Fig. 8, the running paths 4 of the conveyor modules 1 of the transfer unit 20 adjoin one another and form a rising section bridging the height difference. Directly adjacent conveyor modules 1 are each arranged such that a conveyor interface 7 of one conveyor module 1 forming the conveyor input connects to a conveyor interface 7 of the directly adjacent conveyor module 1 forming the conveyor output.

[0195] In order to provide multiple travel levels FE, multiple conveyor modules 1, each forming a horizontal section 21a, are arranged one above the other to form a first conveyor module stack. Furthermore, multiple further conveyor modules 1, each likewise forming a horizontal section 21a, can be arranged one above the other to form a second conveyor module stack. The travel surfaces T of the conveyor modules 1 of the first conveyor module stack and the second conveyor module stack are arranged at different heights. As can be seen in Fig. 9, the conveyor modules 1 of the first conveyor module stack can be connected to the conveyor modules 1 of the second conveyor module stack via one or more riser sections 21b.

[0196] As can be seen from a combination of Fig. 8 and Fig. 9, the rising section can be designed to run helically around a vertical axis, wherein the travel section in the horizontal section 21a is designed according to the course shown in Fig. 6a and in the rising section 21b according to the course shown in Fig. 6b.

[0197] By arranging several conveyor technology modules 1 next to one another and / or one above the other, a suspended conveyor device 22 can be formed. Such a suspended conveyor device 22 with a plurality of conveyor technology modules 1 is shown, by way of example, in a perspective view in Fig. 10 and Fig. 11.

[0198] Fig. 10 shows a section of the overhead conveyor device 22 with two conveyor modules 1 arranged side by side and Fig. 11 with two conveyor modules 1 arranged one above the other. The conveyor modules 1 arranged side by side are connected via the mechanical connection arrangement 8a..8d, in particular via the first and second horizontal connection elements 8c, 8d. The travel routes 4 of the conveyor modules 1 in Fig. 10 adjoin one another and thus form a transport path along which the transport carriers 3 can be moved, in particular traveled. The travel routes 4 of the conveyor modules 1 in Fig. 11 are arranged in different travel levels FE and can be connected to one another, for example, via a transfer unit 20 (not shown).

[0199] Furthermore, the overhead conveyor device 22 can comprise a master computer 23, which is connected to the data transmission system, in particular to the communication unit 11 of the conveyor module 1, in particular via a data transmission network 24. The master computer 23 can be configured to create the path definitions for the transport carriers 3.

[0200] The overhead conveyor device 22 can also have a power supply network 25 to which the power supply systems 38 of the conveyor technology modules 1 can be connected, for example by means of power supplies 9c of the conveyor technology modules 1.

[0201] To allow access for persons to the conveyor modules 1, in particular for maintenance purposes, the overhead conveyor device 22 can have a plurality of service modules 26. Analogous to the conveyor module 1, the service modules 26 can each have a support structure 2a, 2b, 2c comprising a walkable platform 27. As shown in Fig. 11, the service modules 26 can be higher than the conveyor modules 1, in particular twice as high, and arranged next to them. Analogous to the conveyor module 1, the support structure 2a, 2b, 2c of the service module 26 can also have uprights 2b and a frame 2c to which the platform 27 is attached.

[0202] Fig. 12 schematically shows a section of a conveyor system module 1. This shows the transport carrier 3 with the hanging goods W and the support structure 2a, 2b, 2c, in particular the moving platform 2a.

[0203] The hanging garment W comprises, for example, a transport bag with a bag body 28, which is fastened to a hanger 29 and is designed to hold a piece of goods not shown in Fig. 12. Alternatively, the hanging garment W can also be formed by a piece of clothing that hangs on the transport carrier 3 with the help of a coat hanger. The travel route 4 is arranged on the travel surface T and is marked by the travel route marking U, which can be detected in particular optically by the transport carrier 3. In Fig. 12, the travel route 4 is shown in the region of a junction 14, wherein the transport carrier 3 can optionally follow a left or right travel route 4 in the transport direction R at the junction 14. The junction 14 can be marked by a query marking V 1 as described above.

[0204] The transport carrier 3 is preferably designed to detect optically detectable markings, in particular the route marking U and / or the previously described control markings.

The support body 32 can be fastened to the base body 31 in an exchangeable manner, in particular via a connecting device.

[0208] In order to adhere to the running surface T, the transport carrier 3 can have an adhesive force generator 33, by which the transport carrier 3 movably adheres to the support structure 2a, 2b, 2c. The adhesive force generator 33 is arranged on the base body 31, in particular between a first transport carrier side and a second transport carrier side.

[0209] Preferably, the adhesive force generator 33 comprises one or more permanent magnets, via which the transport carrier 3 adheres to the, preferably at least partially ferromagnetic, support structure 2a, 2b, 2c, in particular to the driving platform 2a.

[0210] Alternatively or additionally, the adhesive force generator 33 may comprise adhesive lamellas based on the gecko principle, suction cups, and / or a hook-and-loop fastener, which are arranged on the outer circumference of the drive elements described below. When using adhesive lamellas, suction cups, or a hook-and-loop fastener, the permanent magnets may be omitted or provided in addition to the aforementioned adhesive force generators 33.

[0211] Furthermore, the transport carrier 3 has at least one drive device designed to move the transport carrier 3 along the transport path, in particular along the travel routes 4. Preferably, two drive devices are provided, which are arranged on the opposite sides of the transport carrier.

Preferably, a first motor 35 is coupled to the drive elements on the first transport carrier side, and a second motor 35 is coupled to the drive elements on the second transport carrier side. Alternatively, a single motor 35 can be provided, to which all drive elements are coupled.

[0214] The drive elements can be coupled to the motor 35 via a motor pinion 36 located on the respective motor 35 and via gears 37. The gears 37 are each connected to a drive wheel 34 of the drive wheels 34 and are preferably arranged coaxially with the respective drive wheel 34. The motor pinion 36 can be arranged to mesh with the gears 37 of the respective drive wheels 34. Thus, the drive elements can be coupled to the motor 35 via a gear transmission. Alternatively, a traction drive (not shown) can be provided.

[0215] As an alternative to the illustrated drive via motors 35 arranged on the transport carrier 3, the transport carrier 3 can also be driven using a linear motor principle. For example, primary parts of a linear drive, in particular coils, can be provided along the travel surface T, and a secondary part of the linear drive, for example a short-circuit coil, a separately excited coil, or a permanent magnet, can be provided on the transport carrier 3, so that the arrangement functions as a linear asynchronous motor or linear synchronous motor.

[0216] The conveyor system module 1 can comprise an optional power supply system 38, which is arranged on the support structure 2a, 2b, 2c. To supply the transport carriers 3 with electrical energy, the power supply system 38 can have an electrical line, which runs in particular along the travel path 4. The electrical line preferably comprises an insulator and exposed electrical conductors 39, which are arranged on the travel surface T and run along the travel paths 4.

[0217] The transport carrier 3 can comprise current collectors that are in electrical contact with the electrical conductors 39 and are electrically connected to the motor 35 or motors 35. The current collectors can be designed as sliding contacts that slide and / or rub against the electrical conductors 39 when the transport carrier 3 moves. However, the current collectors can also be wheel- or roller-shaped and roll along the electrical conductors 39. Instead of contact-based energy transmission, contactless energy transmission using an inductive energy supply system 38 could also be provided.

[0218] In particular, the inductive energy supply system can have one or more electrical conductors 39 running parallel to the travel surface T, and a coil arranged on the transport carrier 3 can be electrically connected to the at least one motor 35, wherein the energy transfer takes place in a contactless manner.

[0219] Furthermore, it can be provided that the energy supply system 38, in particular the electrical conductors 39, is only provided on straight sections of the transport route. This allows the energy supply system 38 to be designed more simply.

[0220] Furthermore, the transport carrier 3 and / or the hanging goods W can comprise an optional energy storage device 40, which is electrically connected to the motor 35 or motors 35. The energy storage device 40 can supply the transport carrier 3 with electrical energy in sections where the energy supply system 38 is not present, for example, in curves and / or at junctions 14. This can be provided regardless of whether the energy supply system 38 is designed for contact-based or contactless energy transmission. The energy storage device 40 can be designed, for example, as an accumulator.

[0221] In order to detect the markings, in particular the track marking U and / or the control markings, it is preferably provided that the transport carrier 3 has a detection unit which, for example, comprises a driving surface sensor 41.

[0222] The detection unit of the transport carrier 3 is configured, preferably by means of the travel surface sensor 41, to detect markings arranged along the transport path, in particular the travel path marking U and / or the control markings, for example the query marking VI, the signaling marking V2 and / or the stop marking V3. Thus, the detection unit can be used to guide the transport carrier 3 along the travel path marking U.

[0223] The travel surface sensor 41 is preferably designed as an optical sensor, for example, as a sensor array comprising several optical sensors. The travel path marking U can, for example, be a marking painted, printed, or glued onto the travel surface T that has a different brightness and / or color than the rest of the travel surface T. By evaluating the sensor signal, direction corrections or changes in direction for the transport carrier 3 can be derived. A direction correction or change in direction can be implemented, for example, by controlling the motors 35 differently. Different speeds cause the transport carrier 3 to negotiate a curve.

[0224] It would also be conceivable for the track marking U to be designed as a magnetic strip and the track surface sensor 41 as a magnetic sensor (in particular as a Hall sensor).

[0225] Furthermore, it can be provided that the transport carrier 3 has at least one distance sensor 42. The at least one distance sensor 42 can be designed to detect and / or measure a distance of the transport carrier 3 from another transport carrier 3, for example, one traveling ahead or stationary along the route 4. For example, the distance sensor 42 can be designed as an ultrasonic sensor.

[0226] To control the transport carrier 3, it can have a control unit 43, which is preferably connected to the detection unit, in particular to the driving surface sensor 41, and / or to the at least one distance sensor 42. Fig. 16 shows an exemplary block diagram of the transport carrier 3, in particular of the control unit 43.

[0227] The control unit 43 preferably comprises a drive controller 44, for example designed as a microcontroller, a memory 45 (data and / or program memory) connected to the drive controller 44, power electronics 46 connected to the drive controller 44 and / or a communication module 47 connected to the drive controller 44. In addition, the control unit 43 can comprise an energy management module 48 and the energy storage device 40 connected thereto.

[0228] The communication module 47 can be configured for optical, radio-based, or wired communication. The previously described arrival signal can be transmitted and / or the route definition can be received by means of the communication module 47. The communication module 47 can be connected to the memory 45 for data storage of the route definition.

[0229] Conveniently, the communication module 47 is connected (electronically) to the detection unit and is configured to send the arrival signal as a result of detection of the detection marker V2 by the detection unit.

[0230] The travel control 44 is preferably designed to control and / or regulate a movement of the transport carrier 3 along the travel route 4, preferably on the basis of the path definition stored in the memory 45 and / or on the basis of movement data stored in the memory 45.

[0231] The driving control 44 is configured, for example, to control the at least one drive device, in particular the at least one motor 35, of the transport carrier 3 such that the transport carrier 3 moves along the travel route 4 and in particular tracks the travel path marking U detected by the detection unit.

[0232] It is therefore advantageous if the driving control 44 is (electronically) connected to the detection unit and / or the at least one distance sensor 42.

[0233] In addition, the driving control 44 can be configured to retrieve the route definition from the memory 45 in the area of ​​junctions 14, in particular as a result of detection of a query marking VI by the detection unit, and to follow that route 4 and / or route marking U which is predetermined by the route definition for the respective junction 14.

[0234] Furthermore, the drive control 44 can be configured to control the at least one drive device, in particular the at least one motor 35, of the transport carrier 3 as a result of detection of a stop marking V3 by the detection unit in such a way that the transport carrier 3 brakes, in particular to a standstill.

[0235] Furthermore, the drive control 44 can be configured to regulate the speed of the transport carrier 3. For this purpose, the at least one motor 35 is controlled accordingly by the drive control 44.

[0236] Particularly preferably, the at least one motor 35 is controlled by the drive control 44 via the power electronics 46. For this purpose, the at least one motor 35 can be connected to the power electronics 46.

[0237] It is also advantageous if the drive controller 44 is (electronically) connected to the at least one distance sensor 42. The drive controller 44 can be configured to regulate a distance to the other transport carrier 3 based on the distance measured by the at least one distance sensor 42.

[0238] Fig. 17 shows a picking system 100 with such an overhead conveyor device 22. To better distinguish between travel routes and edges of the conveyor modules 1, the travel routes are shown in dashed lines in Fig. 17.

[0239] The order picking system 100 comprises a warehouse 101, which is formed, for example, by some of the conveyor modules 1 of the overhead conveyor device 22, wherein some of the conveyor modules 1 have a circulation path 17 shown in Fig. 6g in order to provide storage locations 102.

[0240] Furthermore, it can be provided that some of the conveyor technology modules 1 form a travel area, in particular a storage travel area 103, over which the transport carriers 3 can move from the transfer unit 20 to the storage locations 102. For this purpose, the conveyor technology modules 1 can be designed as shown in Fig. 6e. As can be seen in Fig. 17, the conveyor technology modules 1 that form the storage travel area 103 and the conveyor technology that forms storage locations 102 can be arranged next to one another to form a storage level. In order to provide several storage levels arranged one above the other, the conveyor technology modules 1 can be arranged one above the other as shown in Fig. 5.

[0241] In addition, for example, in addition to the storage locations 102, a plurality of previously described service modules 26 can be provided.

[0242] In order to move transport carriers 3 to different storage levels or to remove them from the storage levels, the overhead conveyor device 22 can have at least one transfer unit 20, which is designed in particular as described above.

[0245] The picking system 100 further comprises an order management system 106 for electronically recording picking orders. A customer order comprises at least one picking order. The picking orders are available as data records. The picking orders are electronically recorded on a computer of the order management system 106 and can be transmitted in particular to the master computer 23 (Fig. 10). Each picking order can comprise one or more order lines. If the order specifies multiple order lines, different hanging garments (items) are required. Each order line can contain at least information about the quantity of an ordered hanging garment (item) and about a type of goods. In e-commerce, batch sizes are small, so there is a relatively high number of different picking orders, each with a few order lines. As shown in Fig.17, the overhead conveyor system serves i) to transport hanging goods W with transport carriers 3 from the warehouse 101 to at least one picking station 105, and ii) to store, transport and, if necessary, sort hanging goods W with transport carriers 3 in the warehouse 101, and iii) to sort hanging goods W with transport carriers 3 on the transport movement from the warehouse 101 to at least one picking station 105.

[0246] For this purpose, the order picking system 100 comprises a plurality of functionally different conveyor technology modules 1. The conveyor technology modules 1 are arranged next to one another and / or one above the other and are connected to one another.

[0247] Some of the conveyor technology modules 1 form transport modules 1a. It should be noted that, for reasons of clarity, only a few transport modules 1a are designated in Fig. 17. The transport modules 1a can be constructed according to the described embodiments, in particular according to the embodiments in Figs. 4b, 6a to 6h, and arranged such that the travel paths 4 of the conveyor technology modules 1 form a transport path along which the transport carriers 3 can be moved. The transport modules 1a are arranged next to one another and / or one above the other and are connected to one another.

[0248] Some of the conveyor technology modules 1 form storage modules 1b of the warehouse 101. It should be noted that, for the sake of clarity, only a few storage modules 1b are designated in Fig. 17. The storage modules 1b can be constructed according to the described embodiments, in particular according to the embodiments in Figs. 4b, 6a to 6h, and arranged such that the travel paths 4 of the conveyor technology modules 1 form a transport path along which storage sections or storage locations 102 are arranged, in which the transport carriers 3 can be (statically) stored, and along which the transport carriers 3 can be moved and, if necessary, sorted when they are needed to process picking orders. The storage modules 1b are arranged next to one another and / or one above the other and are connected to one another.Sorting in one or more storage modules 1b is optionally possible and proves advantageous if pre-sorting is to be carried out for a picking order in one or more storage modules 1b. Sorting in one or more storage modules 1b is also possible depending on a warehouse key figure of the warehouse 102, which is defined, for example, by a turnover rate of hanging goods, and / or a warehouse fill level in one or more of the storage modules 1b, and / or a warehouse throughput in one or more of the storage modules 1b, and / or a warehouse level in one or more of the storage modules 1b.

[0251] As can be seen, some of the transport modules 1a and sorting modules 1c can be arranged next to each other and / or one above the other and connected to each other so that the travel paths 4 of the transport modules 1a and sorting modules 1c merge and the transport carriers 3 can be moved between the transport modules 1a and sorting modules 1c.

[0252] As not shown in Fig. 17, some of the storage modules 1b and sorting modules 1c can be arranged next to each other and / or one above the other and connected to each other so that the travel paths 4 of the storage modules 1b and sorting modules 1c merge and the transport carriers 3 can be moved between the storage modules 1b and sorting modules 1c.

[0255] In the exemplary embodiment, a straight track (straight travel section) is shown. It is understood that a curved or bent track (curved travel section) may also be present. A combination of such differently designed track rails is also possible. The rail system 2d may, in particular, also comprise a plurality of track rails and / or a plurality of switches.

[0256] The transport carrier 3 is also designed to correspond to the rail system.

[0266] The conveyor system module 1 can have an electrical power supply system 38 (not shown) arranged on the support structure 2b..2c. The electrical power supply system for supplying the transport carriers 3 with electrical power can have an electrical line running along the travel path 4. For example, the power supply system can comprise a conductor line.

[0267] The electrical energy supply system can have an electrical connection arrangement 9a..9c, as shown schematically in Figs. 1 and 2, for example, via which the electrical energy supply system can be electrically connected to the electrical energy supply system of a further conveyor module arranged on the conveyor module and / or of a further conveyor module arranged next to the conveyor module.

[0268] The conveyor technology module 1 may comprise a data transmission system which is arranged on the support structure 2b..2c, as described above.

[0269] The data transmission system can have a data connection arrangement 10a, 10b, as shown schematically in Fig. 2, for example, via which the data transmission system can be connected to the data transmission system of a further conveyor module 1 arranged on the conveyor module 1 and / or of a further conveyor module 1 arranged next to the conveyor module 1.

[0270] The data transmission system may comprise a communication unit 11, as shown schematically in Fig. 2, for example, which is configured to receive an arrival signal sent by a transport carrier 3 and / or to transmit, in particular to send, a route definition for a transport carrier 3.

[0272] The conveyor technology module 1 comprises a self-propelled transport carrier 3 or several self-propelled and independently controllable transport carriers 3. For this purpose, the transport carrier 3 or each transport carrier 3 comprises an (electrically operated) drive device and an (electronic) drive control.

[0276] The rail system 2d of a third conveyor module 1 runs from the first travel level FE to the second travel level FE and connects to the rail systems 2d of the first and second conveyor modules 1. The rail system 2d of the third conveyor module 1 therefore runs at an incline relative to a base area. The base area is defined by the external dimensions L, W, H of the third conveyor module 1. The transfer unit 20 can have a third travel level FE. The rail system 2d of a fourth conveyor module 1 runs from the second travel level FE to the third travel level FE and connects to the rail system 2d of the second conveyor module 1.

[0277] It should also be noted that the conveyor system module 1 shown in Fig. 4b can be designed with the track layouts shown in Figs. 6a to 6h. To do so, the rail system 2d simply needs to be designed accordingly, for example, using a combination of straight rails, curved rails, and / or switches.
