Removal of a roll adapter from a rail network of a hanging-bag warehouse

Abstract

In order to enable roll adapters (61) on a suspended conveyor device (10) to be removed easily, the roll adapter (61) to be removed is pivoted about a pivot axis relative to the running track (809) from a usage orientation, in which a vertical axis of the roll adapter (61) encloses an angle of between 60° and 120°, preferably 90°, with the running track (809), to a removal orientation, in which the vertical axis of the roll adapter (61) extends between the running track (809) and the conductor track (807). During the pivoting movement of the roller adapter (61) from the usage orientation into the removal orientation, an electric contact between the current collector unit (610) and the conductor track (807) is interrupted. After the roll adapter (61) to be removed has been pivoted into the removal orientation and after the electric contact has been interrupted, the roll adapter is removed via an access region (805) by way of a sideways movement, transverse to the direction of travel, of the roll adapter (61) to be removed.

Description

[0001] REMOVING A ROLL ADAPTER FROM A RAIL NETWORK OF A HANGER BAG WAREHOUSE

[0002] The invention relates to a method for removing one of several rolling adapters which are movable along an overhead conveyor device in a direction of travel for transporting hanging bags which are designed to receive stored goods, wherein the overhead conveyor device comprises a rail network with a track and a power supply system with an electrical conductor track, which conductor track runs at a distance (and preferably parallel) to the track, the rolling adapters each comprise a vertical axis, a drive device with a driven wheel and a power supply with a current collector unit, which power supply is connected to the drive device for driving the driven wheel, and the rolling adapters each roll over the driven wheel on the track of the rail network and are electrically contacted with the conductor track via the current collector unit.

[0003] Furthermore, the invention relates to a suspended conveyor device comprising a rail network with a track, a power supply system with an electrical conductor track, which conductor track runs at a distance (and preferably parallel) to the track,

[0004] Hanging bags for storing goods, and

[0005] Rolling adapters for transporting the hanging bags, wherein the rolling adapters are movable in a direction of travel along the hanging conveyor device, which rolling adapters each have a length measured in the direction of travel, a height axis running orthogonally to the direction of travel, a drive device with a driven wheel and a power supply with a current collector unit, which power supply is connected to the drive device, and which rolling adapters each roll over the driven wheel on the track of the rail network and can be electrically contacted with the conductor track via the current collector unit.

[0006] Furthermore, the invention relates to a storage system for picking stored goods, comprising a loading station for loading hanging bags with stored goods, a storage area for storing hanging bags with stored goods, a packing station for unloading the hanging bags and packing the load goods into shipping packages, and an overhead conveyor device which connects the loading station, the storage area and the packing station, and / or an overhead conveyor device which is arranged in the storage area.

[0007] The invention also relates to a method for carrying out maintenance work on a hanging bag warehouse with hanging bags that can be moved on a network by means of rolling adapters or that can be moved autonomously or at least semi-autonomously by means of the rolling adapters for receiving stored goods, a rolling adapter according to the method, a hanging bag warehouse and a storage arrangement.

[0008] In automated warehouses, production facilities and during goods transport, such as in mail order, it is necessary to load and unload stored goods into and from containers as automatically as possible. The goods can be stored in these containers before delivery and are then transported to a packing station where they are packaged for onward transport to the customer. Transport within the warehouse system is usually carried out via overhead conveyors. The containers are usually hanging bags that are made like fabric bags and are suspended from a rail system at the top with a type of wire hanger. A container of this type is known, for example, from WO 2014 / 012965 A1. Its side wall elements are controlled by a rod system so that the side wall elements, which are connected to one another via a connecting area, can be folded out.In the area of ​​a loading station, the containers are also transferred into a horizontal or inclined position.

[0009] Comparable conveyor containers and associated overhead conveyor devices are known, for example, from DE 102004018 569 A1, EP 2 130 968 A1 or EP 2 196 415 A. The hanging pockets described therein consist of flexible materials in the form of a loop in which the stored goods are held. For loading, these hanging pockets are opened from above in order to be able to place the stored goods into the loop. Unloading takes place by either removing the stored goods from the side of the loop or ejecting them, or, for example, according to EP 2 130 968 A1, by opening the loop downwards. Furthermore, DE 103 54419 A1 discloses a conveyor container which has a relatively rigid and flat plastic wall with a cutout for loading and unloading with stored goods.

[0010] Other conveyor containers are constructed like hanging, flat plastic trays covered on one side with elastic material, which clamps the stored goods. It is known to load such conveyor containers mechanically and unload them manually. The transport cycle is based on the slowest process, which also depends on the quantity of transported goods. In particular, a large number of individual items can slow down loading and / or unloading. For example, the unloading and / or reassembly of disassembled conveyor containers can determine the maximum possible transport cycle. EP 2 686 258 B1 relates to an overhead conveyor device with a hanging pocket for the automatic unloading of loaded goods and with an unloading station. The hanging pocket has a horizontal base on which the goods can be stored for transport purposes.The base interacts with a lifting device which is designed to raise the base of the hanging pocket loaded with at least one item of stored goods, when the hanging pocket is in an unloading position, in a vertical direction in such a way that the at least one item of stored goods can be pushed out centrally through an end face of a base body of the hanging pocket by means of a pushing device, wherein the pushing device has a slide which engages through another end face of the base body into an interior of the base body where the at least one item of stored goods is located when the base is raised. For unloading, the two opposite open end faces, the base which can be lifted in the vertical direction and the slide of the pushing device which extends through one of the end faces are therefore required.

[0011] DE 20 2017 100 206 U1 discloses a conveyor container for an overhead conveyor system for transporting stored goods, which container is adjustable between an open position and a closed position. The conveyor container has a base that is mechanically associated with an ejection device. By means of the ejection device, the base can be adjusted between a transport position, in which the stored goods can be stored within the conveyor container, and an ejection position, in which the stored goods can be ejected from the conveyor container.

[0012] DE 10 2018 105 795 A1 discloses a method for loading or unloading a material container made of a flexible material in an unloading station and / or a loading station of an overhead conveyor, a material container, an unloading station, and an overhead conveyor. The material container is brought closer to the unloading station, where an attractive force is then exerted between the unloading station and the material container to couple the flexible material of the material container. The thus coupled material container is tilted, and the stored material is ejected from the material container in a sliding motion.

[0013] DE 102018 128 417 A1 describes a method for transporting and sorting a hanging bag suspended from a rolling adapter rolling on a rail network of a sorting system for transporting a stored item, comprising providing the rail network of the sorting system, providing the rolling adapter of the hanging bag rolling on the rail network, providing an electrical drive energy for the rolling adapter and converting the provided electrical drive energy by means of the

[0014] The rolling adapter itself converts kinetic energy for transporting the hanging bag. The rolling adapters are used to suspend and move the hanging bags. For this purpose, the rolling adapters each have two coaxially rotating wheels, a suspension arranged between and supported by the wheels, from which the hanging bag is suspended, an electric drive for driving the wheels, and a control device or partial control device for autonomously or at least semi-autonomously controlling the rolling adapter along a path selected from a plurality of paths.

[0015] WO 2020 / 160 585 A2 shows a roller adapter for a hanging conveyor device, which comprises a universally usable base body and a support body which can be exchanged via a connecting device and which, in a first configuration, is provided with a completely enclosed receiving opening for transporting a hanging bag and, in a second configuration, with a hanging hook for transporting goods hanging on a clothes hanger.

[0016] Based on this prior art, the present invention is based on the object of facilitating maintenance work on roller adapters and / or replacement of roller adapters in a hanging bag warehouse with a plurality of hanging bags that can be moved by means of roller adapters, preferably autonomously or at least semi-autonomously movable hanging bags.

[0017] The object is achieved in a method for carrying out maintenance work on a hanging bag warehouse with hanging bags that can be moved on a preferably drag-chain-free, adjusting element-free and / or carrier-free net by means of a rolling adapter or that can be moved autonomously or at least semi-autonomously by means of the rolling adapters for receiving stored goods by selecting a rolling adapter to be removed, to which a hanging bag is preferably attached, preferably separating the hanging bag from the rolling adapter, creating a free path on the net, pivoting the rolling adapter and removing the pivoted rolling adapter through a free space, wherein the free space is arranged between an energy-conducting layer and a traction layer of the net.

[0018] The selected rolling adapter can be pivoted about a pivot axis that preferably runs transversely to a direction of travel, in particular about a wheel axis of the rolling adapter. The rolling adapter can be pivoted into the free or cleared path, whereby the shaft and head of the rolling adapter are initially located in the free path of the net. The free path can be understood as a section of the net on which no other rolling adapter is currently located. The free space can be understood as a clear height on the free path that exists between the energy-conducting layer and the traction layer. In particular, the free space can be unrestricted on both sides in a Y-direction, i.e. transversely to the direction of travel of the rolling adapters, which means that the energy-conducting layer and the traction layer are arranged at a distance from one another.However, it is also conceivable for the free space in the direction of travel or X-direction to be vertically limited on one side, so that the rolling adapter can be removed from at least one side. A traction layer can be understood as a roadway on which wheels of the rolling adapter can roll, preferably also in order to transmit driving forces or braking forces under traction. An energy-conducting layer can be understood as any device for transferring energy from the energy-conducting layer to the rolling adapters, and vice versa, in particular energy for driving and / or braking the rolling adapters. Traction is preferably achieved by gravity, by means of which the wheels can be pressed against traction surfaces of the traction layer. Alternatively or additionally, however, a spring force can also be used to press the wheels against the traction layer.Particularly preferably, the energy-conducting layer is arranged vertically above the traction layer in the direction of gravity. The spring force can act between the energy-conducting layer and the traction layer. Inserting a rolling adapter into the net can be done in the reverse order, whereby if necessary, a position for insertion must first be selected and the free path created there, then the rolling adapter with the Z-axis aligned horizontally (i.e., the vertical axis of the rolling adapter) must be inserted into the free path, i.e., the free space, and then pivoted back 90 degrees with the shaft between the traction surfaces of the traction layer so that the Z-axis is vertical. Optionally, the free space can then be reoccupied with additional rolling adapters.Similarly, to create the free space, rolling adapters previously located there can be pushed away, preferably by means of a manually applied force, or moved away, preferably autonomously or at least semi-autonomously.

[0019] Preferably, the coupling for transferring energy between the rolling adapters to be relocated and the energy-carrying layer can be maintained when creating the clear path. This is preferably done during the pushing process and / or particularly preferably during an autonomous or at least semi-autonomous movement of the rolling adapters to be relocated. Decoupling can be eliminated, and the energy supply for the rolling adapters to be relocated can be guaranteed throughout the entire removal process. This allows, for example, energy-requiring storage and travel processes, and / or maneuverability on the network to be carried out or maintained.

[0020] In a preferred embodiment, the selected rolling adapter is pivoted, preferably around a wheel axle, by manual force. The rolling adapters have a preferably traction-supported coupling to the net of the hanging bag storage system via the wheels, whereby an existing pivot axis can be utilized with the wheel axle. For this purpose, the wheels can be switched to freewheel mode. Alternatively, pivoting can also be achieved by rolling the wheels on the net with the wheels locked. The pivoting movement then occurs around a horizontally moving pivot axis through the contact surfaces of the wheels on the net.

[0021] Alternatively or additionally, the clear path on the network is created by means of autonomous driving maneuvers of the additional rolling adapters, whereby the rolling adapters each have their own moving drive and a longitudinal dynamics control system that controls this, or optionally by moving the additional rolling adapters away from the selected rolling adapter using manual forces, for example pushing them away in the X direction. It is therefore possible to create the required clear path either through manual intervention or by means of driving maneuvers. The driving maneuvers can preferably be controlled by a central control device and / or locally. Particularly preferably, the clear path can be created directly by the rolling adapter to be removed. For this purpose, it is conceivable that the rolling adapter to be removed is in a data connection with the rolling adapters to be moved, directly or indirectly via the central control system.For this purpose, messages, particularly driving instructions, can be exchanged between the rolling adapter to be removed and the one to be relocated. By creating a clear path, the operator's work can be made easier and, at the same time, it can be indicated which rolling adapter is to be removed, significantly facilitating maintenance work on the rolling adapter. Alternatively or additionally, signals to the operator are also conceivable, for example, a visual and / or acoustic display to identify the rolling adapter to be removed. If necessary, the relocated rolling adapters can be manually or autonomously returned to their original location on the network after removal.It was recognized that, compared to conventional couplings, such as drag chains or drivers, the dedicated drive allows for rotational and translational degrees of freedom for the rolling adapter and the other rolling adapters, which can be advantageously used for removing and inserting the rolling adapter. In particular, it was recognized that these degrees of freedom and the dedicated drive, in combination with the free space, enable particularly easy maintenance, removal, and insertion of the rolling adapters. The free space is drag chain- and driver-free. This is also only possible with the dedicated drive.

[0022] The problem is also solved by a rolling adapter configured, designed, and / or programmed to perform a previously described method. This results in the advantages described above.

[0023] The object is further achieved in a rolling adapter for transporting a hanging bag in a hanging bag storage in that it interacts with a net of the hanging bag storage, wherein the net has a traction layer with two parallel and spaced-apart traction surfaces and an energy-conducting layer arranged above it, wherein the rolling adapter can be removed from the net by means of a manual intervention or inserted into the net in that it can be pivoted about an axis running transversely to a direction of travel, preferably a wheel axis of the rolling adapter, a maximum length seen in the direction of travel, in particular of a head and a shaft,of the rolling adapter is smaller than a distance between the traction layer and the energy-conducting layer of the net, and a width of the shaft of the rolling adapter, viewed transversely to the direction of travel, does not exceed a distance remaining between the traction surfaces of the net at any point over its entire extent. The shaft of the rolling adapter can therefore be arranged between the traction surfaces during a travel movement and can be inserted into and removed from the net without destruction and without assembly work. Furthermore, the rolling adapter is preferably set up, designed, and / or programmed to carry out a method described above. This also results in the advantages described above. The task is also in a hanging bag warehouse for storing and sorting goods that can be accommodated in hanging bags, which interacts with a previously described rolling adapter and / or is filled with such a rolling adapter, with a net on which the rolling adapters roll,This is achieved in that the net has a traction layer with two traction surfaces running parallel to one another at a distance, on which wheels of the rolling adapters can roll to carry out travel movements on the net, and an energy-carrying layer arranged above it, by means of which the rolling adapters can be supplied with drive energy to carry out the travel movements on the net, wherein the distance between the traction surfaces of the net is greater than a maximum width of the shaft of the rolling adapter seen transversely to the direction of travel,The height of the free space between the traction layer and the energy-conducting layer of the net is greater than the maximum length of the rolling adapter, viewed in the direction of travel. This dimensioning allows the rolling adapter to fit into the free space even when pivoted, and the shaft of the rolling adapter can be positioned between the traction surfaces during travel when not pivoted, and can be passed through between them for insertion or removal. For insertion or removal, the rolling adapter can be freely displaced transversely to the direction of travel or in the Y-direction when pivoted. Maximum width or length means that the shaft of the rolling adapter, across its entire length, never exceeds the distance remaining between the traction surfaces of the net. The rolling adapter and the remaining hanging pocket bearings work together,In particular, the dimensioning of the rolling adapter and the network of the hanging bag storage system makes maintenance work on rolling adapters and / or the replacement of rolling adapters simpler and easier. The hanging bag storage system is preferably configured, programmed, constructed, and / or has a previously described rolling adapter to carry out a previously described method. Furthermore, the previously described advantages result.

[0024] In a preferred embodiment of the hanging pocket storage system, it is provided that a clearable path of the net exceeds the height H of the rolling adapters by a factor greater than 1, in particular a factor between 1.5 and 2. When pivoted by 90°, the total height of the rolling adapter corresponds to an extension in the direction of travel or the X-direction. With a factor of 1, the rolling adapter can therefore just be removed without collision. With larger factors, removal can be carried out particularly comfortably. The hanging pocket storage system is designed such that the path can be cleared by pushing away the other rolling adapters. In particular, mounting devices to which, for example, the energy-conducting layer and the traction layer are held are arranged at a sufficiently large distance from one another, in particular at least as large as the clear path to be created.

[0025] Alternatively or additionally, it is also possible for the free space in the direction of travel of the rolling adapters to be delimited on both sides by a mounting device, wherein the energy-carrying layer and the traction layer are held on the mounting device. The mounting devices can provide a distance between the energy-carrying layer and the traction layer. Preferably, these are held in the Z direction exclusively by means of the mounting devices, thus requiring no further mounting means. Particularly preferably, the mounting devices have a recess, closed or half-open, through which a travel path of the rolling adapters runs. This makes it possible to provide the travel path as well as the free space for inserting and removing the rolling adapters, the energy supply and the traction surfaces for a traction drive of the rolling adapters. Furthermore, a comparatively simple structure of the network results.

[0026] Finally, the object of a storage arrangement for storing, sorting, and / or picking stored goods is achieved by a plurality of previously described roller adapters, a plurality of hanging pockets, each of which can accommodate at least one stored item and which are attached to the roller adapter and can be detached therefrom without causing damage, and a previously described hanging pocket storage system in which the hanging pockets attached to the roller adapter and by means of the latter can be stored, relocated, sorted, and / or picked, with individual roller adapters being optionally removable from the rest of the storage arrangement using a previously described method. The advantages described above arise from the interaction of the hanging pocket storage system, the roller adapters that can be inserted into and removed from it, and the hanging pockets that can be attached to them.

[0027] It is an object of the present invention to provide a method for easily removing roller adapters on an overhead conveyor device and a corresponding overhead conveyor device.

[0028] The object is achieved by a method for removing one of several rolling adapters, which are movable along a suspended conveyor device in a direction of travel, preferably semi-autonomously or autonomously, for transporting hanging bags, which are designed to receive stored goods, wherein the suspended conveyor device comprises a rail network with a track and a power supply system with an electrical conductor track, which conductor track runs at a distance, preferably parallel, to the track, the rolling adapters each comprise a height axis, a drive device with a driven wheel and a power supply with a current collector unit, which power supply is connected to the drive device for driving the driven wheel, and the rolling adapters each roll over the driven wheel on the track of the rail network and are contacted with the conductor track via the current collector unit, comprising the steps

[0029] Pivoting the rolling adapter to be removed about a pivot axis relative to the roadway from a use orientation, in which the height axis of the rolling adapter forms an angle of between 60° and 120°, preferably 90°, with the roadway, into a removal orientation, in which the height axis of the rolling adapter runs (essentially) between the roadway and the conductor track, preferably (essentially) parallel to the direction of travel, wherein during the pivoting movement of the rolling adapter from the use orientation to the removal orientation, an electrical contact between the current collector unit and the conductor track is interrupted (by opening a current contact), and

[0030] Removal of the rolling adapter to be removed after pivoting into the removal orientation and after interrupting the electrical contact between the current collector unit and the conductor track via an access area (located between the track and the conductor track) by a sideways movement of the rolling adapter to be removed transversely to the direction of travel.

[0031] Furthermore, the object is achieved by a suspended conveyor device, in particular for carrying out the said method, wherein the suspended conveyor device comprises: a rail network with a track, a power supply system with an electrical conductor track, which conductor track runs at a distance, preferably parallel, to the track,

[0032] Hanging bags for storing goods, and

[0033] Rolling adapters for transporting the hanging bags, wherein the rolling adapters are movable in a direction of travel along the overhead conveyor device, which rolling adapters each have a length measured in the direction of travel, a height axis running orthogonally to the direction of travel, a drive device with a driven wheel and a power supply with a current collector unit, which power supply is connected to the drive device for driving the driven wheel, and which rolling adapters each roll over the driven wheel on the track of the rail network and can be contacted with the conductor track via the current collector unit, wherein a rolling adapter for removal from the overhead conveyor device about a pivot axis relative to the track from a use orientation, in which the height axis of the rolling adapter forms an angle between 60° and 120°, preferably 90°, with the track, into a removal orientation,in which the vertical axis of the rolling adapter runs (essentially) between the track and the conductor track, preferably (essentially) parallel to the direction of travel, and is pivotable, wherein on the pivoting movement of the rolling adapter from the use orientation to the removal orientation, an electrical contact between the current collector unit and the conductor track can be interrupted (by opening a current contact), and the distance between the conductor track and the track is greater than the length of the rolling adapter to be removed, wherein the distance defines an access area, so that in the removal orientation, the rolling adapter to be removed can be removed from the overhead conveyor device via the access area by a sideways movement running transversely to the direction of travel.

[0034] It should be noted at this point that, according to the invention, the roller adapters are designed for transporting hanging bags. However, this is by no means limiting. Rather, the roller adapters are equally designed for transporting hanging garments hung on a coat hanger. For example, the hanging garment could be a suit, a business suit, a jacket, or a blazer.

[0035] Preferably, the electrical conductor track of the power supply system runs parallel to the roadway at a (at least approximately) constant distance. This enables a reliable power supply and eliminates the need to compensate for variable distances between the conductor track and the electrical conductor track.

[0036] Since the rolling adapters are supplied with electrical power via the power supply system, an energy storage device (e.g., an accumulator) on the rolling adapter is no longer required. In other words, the drive energy is provided by the power supply system.

[0037] The rolling adapters can be moved semi-autonomously or autonomously along the overhead conveyor.

[0038] In other words, the rolling adapters each have their own drive, and they can be moved independently (decoupled) on the rail network. The overhead conveyor system does not require an additional external drive device that simultaneously applies a driving force to the rolling adapters, as is the case with drag chains, for example, in the prior art. The rolling adapters can also be moved at different speeds.

[0039] Since the overhead conveyor does not require any additional external drive device, the roller adapters are particularly easy to access and can be removed from the overhead conveyor particularly easily.

[0040] Removing a rolling adapter requires only the steps of pivoting the rolling adapter to be removed and then removing it. Removing the rolling adapter can be done, for example, to perform (planned) maintenance work on a rolling adapter and / or the rail network, particularly on the track and / or electrical conductors.

[0041] However, removal can also occur due to a defect in a rolling adapter and / or to replace wearing parts and / or to measure parameters and / or to test the functionality of a rolling adapter.

[0042] It should be noted that a single roller adapter or individual roller adapters or all roller adapters can be removed from the overhead conveyor as required.

[0043] The rolling adapter is used to remove the overhead conveyor device around a pivot axis from the use orientation to the removal orientation.

[0044] In the usage orientation, the vertical axis of the rolling adapter forms an angle of between 60° and 120°, preferably 90°, with the track. This enables stable support of the rolling adapter via the driven wheel on the rail network, even during dynamic travel movements of the rolling adapter. In the removal orientation, the rolling adapter is pivoted relative to the track so far that the vertical axis runs (essentially) between the track and the conductor track. The vertical axis does not necessarily have to lie between the track and conductor track, but can intersect the track and / or the conductor track. Removing the rolling adapter to be removed after pivoting into the removal orientation can prove particularly advantageous if the vertical axis runs (essentially) parallel to the direction of travel.

[0045] The pivoting movement of the rolling adapter is limited by the distance between the track and the conductor track, which defines the extent of the access area, and the length of the rolling adapter. Therefore, the position of the height axis relative to the track and / or conductor track during removal is determined by the geometric conditions.

[0046] In any case, the extent of the access area is dimensioned such that the rolling adapter to be removed can be removed via the access area by a sideways movement of the rolling adapter to be removed perpendicular to the direction of travel. In other words, the extent of the access area is greater than the height of the rolling adapter.

[0047] Since the rolling adapter to be removed can be removed from the side of the overhead conveyor, in particular from the rail network, it is possible to remove a rolling adapter into virtually any section of the rail network and / or to remove any rolling adapter from a plurality of rolling adapters. It is not necessary to move the rolling adapter to be removed into a specially configured section of the rail network in order to remove the rolling adapter from the overhead conveyor, in particular from the rail network.

[0048] The rolling adapters can each comprise a signal processing unit that communicates with a (central) control device. Communication between the control device and the respective signal processing units preferably takes place via a wireless communication network, for example via a radio network. The signal processing unit is preferably designed to receive electronic control commands from the control device, process electrical signals, for example from a sensor arrangement, and / or generate switching commands. The control device can control and / or monitor the travel movements of the rolling adapters. In particular, the travel movements can be used to specify a (planned) travel route for the rolling adapters on the rail network; for example, the rolling adapters should travel to selected packing stations of the warehouse system.In particular, the travel movements can be monitored, for example, when position data is determined from the rolling adapters to determine the current position of the rolling adapters relative to the rail network. The control unit can also specify travel speeds. The rolling adapters can also be moved at different speeds. For example, rolling adapters arranged one behind the other on the rail network can be moved relative to each other at different speeds to either increase or decrease the distance between the rolling adapters in the direction of travel. This makes it particularly easy to implement a buffer function for rolling adapters.

[0049] The drive device preferably comprises an electric drive that communicates with the signal processing unit. The drive is connected to the driven wheel and can move the rolling adapter in the direction of travel along the rail network. The drive can enable forward and / or reverse movement of the rolling adapter. The drive can also be referred to as a longitudinal dynamic control system. The signal processing unit can receive electronic control commands, in particular for controlling the electric drive of the drive device.

[0050] If the rolling adapter also includes a steering device with a steering element, as described, for example, in WO 2019 / 234046 A2, the rolling adapter can comprise, in addition to the travel drive, a steering drive connected to the steering element. In this embodiment, the driven wheel is not steerable. This allows the rolling adapter to branch off into different paths at intersections along the rail network. At the intersections, the rolling adapter can either travel straight ahead, turn left, or turn right. The intersections can be designed to be "passive" and do not require switching tongues or the like. The steering drive can also be referred to as lateral dynamics control.

[0051] While the driven wheel is not steerable according to the above embodiment, it is also possible for the driven wheel to be mounted on the steering element and pivot about a steering axis. This allows the rolling adapter to branch off into different routes at intersections along the rail network. The signal processing unit can receive control commands, in particular for controlling a steering drive of the steering device.

[0052] It can therefore be provided that the signal processing unit can receive control commands, in particular for controlling the electric drive of the drive device and / or for controlling a steering drive of the steering device. The rolling adapters can each comprise a (writable and readable) data memory which is connected to the signal processing unit of the rolling adapter. The data memory can be used to store data if, for example, the rolling adapters are not supplied with power due to a malfunction, such as a power failure. The data can in particular comprise position data of the rolling adapters, so that after the malfunction has been rectified, the signal processing unit of the rolling adapters can transmit the position data to the control unit.

[0053] The method preferably comprises the additional step of selecting a rolling adapter from the plurality of rolling adapters, which defines the rolling adapter to be removed. This allows a decision to be made as to which of the rolling adapters arranged on the rail network is to be removed. This selection can be made randomly, for example, or depending on rolling adapter-specific parameters, such as service life, mileage, and the like. For example, all rolling adapters of the overhead conveyor device can be monitored, and if an error or defect occurs, for example, a relevant rolling adapter can be selected and removed from its current position or from any other suitable position along the rail network.

[0054] The selection of a roller adapter from among several roller adapters can be performed, for example, by a (central) control unit of the overhead conveyor. This allows the control unit to select specific roller adapters for maintenance at scheduled maintenance intervals.

[0055] Generally, a number of rolling adapters can be selected to define a number of rolling adapters to be removed. This means that multiple rolling adapters (e.g., a group of rolling adapters) can also be selected to define a number of rolling adapters to be removed. The selected rolling adapters to be removed can then be pivoted (individually) and removed as described.

[0056] Preferably, the rolling adapter is pivoted from the use orientation to the removal orientation by applying a mechanical force to the rolling adapter. This ensures quick and safe pivoting. The mechanical force can be applied by an operator or a mechanical actuator, for example, an electrically operated pivot drive.

[0057] The rolling adapter to be removed can be provided with a hanging pocket coupled to the rolling adapter, with the hanging pocket being uncoupled before the rolling adapter to be removed is pivoted. If a hanging pocket is coupled to the rolling adapter to be removed, it is preferably removed before the rolling adapter to be removed is pivoted, which is particularly advantageous if the hanging pocket would not allow the rolling adapter to be pivoted into the removal orientation due to its dimensions. The uncoupling can be performed manually by an operator or by a mechanical actuator, for example, a robot.

[0058] Furthermore, before the pivoting step, a clear path can be created along the overhead conveyor system before and / or after the roller adapter to be removed. This is particularly advantageous if, for example, another roller adapter is located within the pivoting range of the roller adapter to be removed.

[0059] The creation of the free path along the overhead conveyor device before and / or after the rolling adapter to be removed along the overhead conveyor device can further comprise the steps:

[0060] Determination of a blockage section based on a length of the free path by a control device, and

[0061] Detection of a roll adapter arranged before or after the roll adapter to be removed on the overhead conveyor in the blocking section by the control device, and

[0062] Control of the detected rolling adapter arranged before and / or after the rolling adapter to be removed on the overhead conveyor device in the blocking section by actuating the drive device in such a way that the detected rolling adapter is moved out of the blocking section.

[0063] A control device may be provided which is designed to

[0064] Determination of a blockage section based on the length of a free path along the overhead conveyor device before and / or after the rolling adapter to be removed,

[0065] Detection of a rolling adapter arranged before and / or after the rolling adapter to be removed on the overhead conveyor in the blocking section, and

[0066] Controlling a recognised rolling adapter arranged in front of the rolling adapter to be removed on the overhead conveyor device by actuating the drive device in such a way that the recognised rolling adapter is moved out of the blocking section, and / or controlling a recognised rolling adapter arranged after the rolling adapter to be removed on the overhead conveyor device by actuating the drive device in such a way that the recognised rolling adapter is moved out of the blocking section.

[0067] Preferably, the central control device can carry out the said method steps.

[0068] If a rolling adapter blocks a pivoting movement of the rolling adapter to be removed, a free path is created.

[0069] According to this design, a rolling adapter in the blocking section is detected by the control device and defined as a detected rolling adapter. The detected rolling adapter can be positioned in the direction of travel before or after the rolling adapter to be removed. If multiple rolling adapters are detected in the blocking section by the control device, these are defined as detected rolling adapters. The detected rolling adapters can be positioned in the direction of travel before or after the rolling adapter to be removed, or in the direction of travel before and after the rolling adapter to be removed.

[0070] To create the free path, the detected rolling adapter(s) are moved out of the blocking section, creating sufficient space to allow the rolling adapter to be removed to pivot freely. If multiple rolling adapters are to be removed, the free path is correspondingly longer than if only one rolling adapter is to be removed.

[0071] According to this embodiment, it is advantageous that the detected rolling adapter is moved out of the blocking section by controlling the drive device of the detected rolling adapter or the detected rolling adapters are moved out of the blocking section by controlling the drive devices of the detected rolling adapters.

[0072] The free path is therefore generated by automatically moving out the recognized rolling adapter or the recognized rolling adapters.

[0073] Before and / or during the pivoting step and after the creation of the free path, the rolling adapter to be removed can also be moved in the direction of travel or against the direction of travel to ensure that the pivoting can be carried out unhindered. Preferably, the control device can also ensure that no further rolling adapters move into the blocking section until the rolling adapter(s) to be removed have been removed. This method step can also be carried out by the central control device.

[0074] Creating the free path along the overhead conveyor device before and / or after the roller adapter to be removed along the overhead conveyor device may also include the following steps:

[0075] Applying a mechanical force to a rolling adapter located in the blocking section, which is detected in front of and in front of the rolling adapter to be removed on the overhead conveyor, such that the rolling adapter is moved out of a blocking section, which is specified based on a length of the free path, and / or

[0076] Applying a mechanical force to a rolling adapter arranged on the overhead conveyor device after the rolling adapter to be removed in such a way that the rolling adapter is moved out of a blockage section which is predetermined based on a length of the free path.

[0077] Even according to this design, a free path is created if a rolling adapter blocks a pivoting movement of the rolling adapter to be removed.

[0078] According to this design, a rolling adapter in the blocking section is optically detected, for example by an operator or a camera system, and defined as a detected rolling adapter. The detected rolling adapter can be positioned in the direction of travel before or after the rolling adapter to be removed. If multiple rolling adapters are detected in the blocking section, they are defined as detected rolling adapters. The detected rolling adapters can be positioned in the direction of travel before or after the rolling adapter to be removed, or in the direction of travel before and after the rolling adapter to be removed.

[0079] To create the free path, the detected rolling adapter(s) are subjected to a mechanical force and moved out of the blockage section, creating sufficient space to allow the rolling adapter to be removed to move freely. If multiple rolling adapters are to be removed, the free path is correspondingly longer than if only one rolling adapter is to be removed.

[0080] The mechanical force can be applied by an operator. In principle, the mechanical force can also be applied by a feed drive that communicates with a (central) control unit, which in turn receives image data from a camera system from the optical detection of the rolling adapter(s) in the blocking section and generates control commands to actuate the feed drive and apply the mechanical force to the rolling adapter(s).

[0081] The mechanical force can be exerted on one of the rolling adapters, which in turn applies a thrust force to at least one rolling adapter arranged upstream of it in the direction of travel.

[0082] If several detected rolling adapters are to be moved out of the blocking section, a first group of detected rolling adapters can be controlled, as described above, by actuating the associated drive device in order to move this group of detected rolling adapters out of the blocking section, and a second group of detected rolling adapters can be subjected to a mechanical force, as described above, in order to move the second group of detected rolling adapters out of the blocking section.

[0083] The control device may be configured to receive position data of the detected rolling adapter while the rolling adapter is moved out of the blocking section.

[0084] The creation of the free path along the overhead conveyor device before and / or after the rolling adapter to be removed along the overhead conveyor device may comprise the following step:

[0085] Determination of position data of the detected rolling adapter during and / or after the rolling adapter is moved out of the blocking section and provision of the position data to a control device.

[0086] Preferably, the central control device can carry out the said method step.

[0087] By providing the position data, it can be ensured that the position of the rolling adapter moved out of the blocking section or the positions of the rolling adapters moved out of the blocking section is or are known to the (central) control device. For this purpose, it is only necessary that a travel drive of the drive device of the rolling adapter comprises an electric motor, for example with an incremental encoder, or that the drive device of the rolling adapter comprises an absolute position measuring system (absolute encoder), for example a measuring wheel arranged on the rolling adapter and rolling on the rail network, which is coupled to an encoder in order to determine the position data from a relative position or absolute position. It can be monitored when and whether the detected rolling adapter(s) have left the blocking section.The position data can be recorded on the rolling adapter by the signal processing unit and transmitted to the (central) control device.

[0088] The rolling adapter to be removed can be pivoted around a pivot axis running orthogonally to the direction of travel. This allows pivoting in or against the direction of travel, making the pivoting process of the rolling adapter from the use orientation to the removal orientation particularly easy. The electrical contact between the current collector unit and the conductor track is broken particularly reliably, and the removal of the rolling adapter to be removed via the access area is also easy, as removal occurs via a sideways movement of the rolling adapter to be removed perpendicular to the direction of travel.

[0089] The pivot axis is preferably formed by a wheel axis or a wheel support line of a wheel, preferably the driven wheel.

[0090] Preferably, the rolling adapters each have only one wheel, which is designed as a driven wheel and forms a wheel axle.

[0091] The drive device may comprise a plurality of wheels rolling on the roadway, wherein at least one of the wheels forms the driven wheel.

[0092] Preferably, the rolling adapters each have only two wheels that form a wheel axle.

[0093] One of the wheels can be driven and one of the wheels can be non-driven, which allows cornering to be carried out in a way that reduces wear.

[0094] Preferably, the rolling adapters each have only one wheel axle, which facilitates the pivoting of a rolling adapter to be removed.

[0095] Alternatively, both wheels can be driven. For this purpose, the driven wheels can each be coupled to a drive motor. If both wheels are driven, the rolling adapter can be steered by differential speed control of the wheels. Therefore, in this design, the drive motors form the lateral dynamic control described above. Each drive wheel is driven at a different speed to rotate the rolling adapter around its vertical axis. To move forward or backward, however, both drive motors are driven at the same speed. In this design, the drive motors also form the traction drive.

[0096] Preferably, the rolling adapters can each have two wheels with the same wheel axle and the rolling adapter can only form one wheel axle.

[0097] According to a preferred embodiment, the pivot axis is formed by a wheel axle or a wheel support line of the driven wheel. As described above, the wheel axle can also be formed by a wheel axle of two wheels, with at least one of the wheels being driven.

[0098] The pivot axis can run orthogonally to the direction of travel and is preferably formed by a wheel axle of one wheel of the rolling adapter, preferably the driven wheel, or by a wheel axle of two wheels of the rolling adapter (at least one of the wheels is a driven wheel). If the wheel axle is used as a pivot axis in the aforementioned designs, the rolling adapter can be easily pivoted while the wheel rests on the roadway or while the wheels rest on the roadway. This enables particularly simple and smooth pivoting.

[0099] A wheel support line of one wheel of the rolling adapter, preferably the driven wheel, or a wheel support line of two wheels of the rolling adapter can also be used as the pivot axis. This enables particularly simple and smooth pivoting.

[0100] Additional swivel axes are also possible if the rolling adapter is raised before or during swiveling.

[0101] Preferably, the track comprises two track sections arranged parallel to each other at a distance from each other, and running surfaces formed on the track sections. This ensures particularly good (height) guidance of the rolling adapter on the track. The running surfaces can also be referred to as traction surfaces. The track sections can be arranged at a constant distance from each other.

[0102] Preferably, the drive device comprises a plurality of wheels, with at least one of the wheels forming the driven wheel, and with one of the wheels rolling on the running surface of one of the track sections and another of the wheels rolling on the running surface of another of the track sections. By assigning a first wheel to the first running surface and a second wheel - 1 - to the second running surface, even better guidance of the rolling adapter on the track is ensured.

[0103] Other configurations are also conceivable. For example, the roadway can comprise two track sections arranged at a distance from each other and parallel to each other, with running surfaces formed on the track sections, with only the driven wheel rolling on the running surface of one of the track sections and—instead of another wheel—a sled-like sliding body sliding on the running surface of another of the track sections.

[0104] The rolling adapters can each comprise a shaft which is arranged between the track parts in the orientation of use and protrudes downwards from a gap between the track parts with a lower shaft section.

[0105] It may prove advantageous if the track sections form inner boundary walls facing one another, and the lower shaft section forms outer stop walls facing away from one another, with the outer stop walls being designed to complement the inner boundary walls. This allows the rolling adapter to be limited during a deflection movement in a direction orthogonal to the direction of travel. The inner boundary walls can additionally form guide surfaces, and the outer stop walls can additionally form guide surfaces, so that during a movement in the direction of travel and a deflection of the rolling adapter (in a direction orthogonal to the direction of travel), the guide surfaces of one of the inner stop walls and one of the outer stop walls engage.

[0106] Preferably, a pocket holder is provided on the lower shaft section, which is designed for attaching a pocket. If such a pocket holder is provided, it is particularly advantageous if a connected pocket is decoupled before pivoting the rolling adapter.

[0107] The placement of the hanging bag holder in the lower shaft section of the rolling adapter allows the hanging bag to be transported hanging. This simultaneously creates a low center of gravity, which stabilizes the rolling adapter. This allows for reliable transport even with a single wheel axle (with one or more wheels, one or more of which are driven).

[0108] A lower shaft section protruding downwards from the gap can form a maximum width measured orthogonally to the direction of travel, whereby the distance between the track sections is greater than the maximum width. This ensures that, regardless of the position of the rolling adapter on the rail network, the lower shaft section can always be pivoted up through the gap and between the track sections. If the distance between the track sections is not consistently greater than the maximum width of the lower shaft section protruding from the gap at the bottom over the entire track of the rail network, it is advantageous if this condition is met in at least one section of the track of the rail network, i.e. the distance between the track sections is greater than the maximum width of the lower shaft section.This allows the lower shaft section to easily pivot upwards through the gap and between the roadway sections. Likewise, an upper shaft section that protrudes upwards (in whole or in part) from the gap can form a maximum width perpendicular to the direction of travel, which is smaller than the distance between the roadway sections.

[0109] A mounting device can be provided to which the rail network with the track and the power supply system with the electrical conductor track are mounted, in particular detachably. In addition to being easy to mount and dismount, the mounting device can easily specify the distance between the conductor track and the track, and thus the access area. The access area can, for example, be additionally delimited on both sides in the direction of travel by a mounting device. Alternatively, a connecting wall between the rail network and the power supply system, interrupted in sections by windows to create the access area, but otherwise continuous, is also conceivable.

[0110] Preferably, the current collector unit comprises a current collector and the electrical conductor track comprises a conductor track section, wherein in the use orientation of the rolling adapter, the current collector and the conductor track section form an electrical contact.

[0111] The current collector unit can also have multiple current collectors, with the electrical conductor track comprising several electrically insulated conductor track sections. In the intended use orientation of the rolling adapter, the current collectors and the conductor track sections each form an electrical contact.

[0112] The current collector (or collectors) can (or can each) comprise a sliding body with a front end region in the direction of travel and a rear end region in the direction of travel, wherein the sliding body (in each case) forms a front clearance in the front end region on an upper side facing the conductor track section and / or wherein the sliding body (in each case) forms a rear clearance in the rear end region on an upper side facing the conductor track section.

[0113] The design of a front and / or rear clearance ensures that the respective grinding wheels do not jam or become jammed with the conductor track when pivoting and removing the rolling adapter. Furthermore, the front and / or rear clearance allows existing step changes at roadway crossings along the rail network to be crossed with minimal wear.

[0114] The front and / or rear clearances can be formed by rounding the front end area and / or rounding the rear end area. This ensures electrical contact in any position of the rolling adapter.

[0115] The front and / or rear reliefs can be formed by a bevel of the front end region and / or a bevel of the rear end region. Such a relief is particularly easy to produce.

[0116] Preferably, the front clearance and / or rear clearance of the grinding bodies (each) forms an engagement surface facing the conductor track section, which is / are arranged and designed in such a way that a sliding movement between the grinding body and the conductor track section is made possible on the pivoting movement of the rolling adapter from the use orientation to the removal orientation.

[0117] The current collector unit or units can be mounted on a bracket via a spring element. This compensates for minor fluctuations in the distance between the track and the electrical conductor track, ensuring reliable electrical contact between the current collector unit and the conductor track section, or between the current collector units and the conductor track sections.

[0118] The pantograph can be mounted on the rolling adapter so that it can move about an articulated axis that runs orthogonal to the direction of travel, provided that a pantograph is provided. The pantograph can be arranged on a receiving support, and the receiving support is mounted on the rolling adapter so that it can move about an articulated axis that runs orthogonal to the direction of travel. If several pantographs are provided, the pantographs can be mounted on the rolling adapter so that they can move about an articulated axis that runs orthogonal to the direction of travel. The pantographs can be arranged on a receiving support, and the receiving support is mounted on the rolling adapter so that it can move about an articulated axis that runs orthogonal to the direction of travel. Alternatively, the pantographs can each be arranged on a receiving support, and the receiving supports are each mounted on the rolling adapter so that they can move about an articulated axis that runs orthogonal to the direction of travel.

[0119] If the current collector is mounted on the rolling adapter so it can move about a joint axis running orthogonal to the direction of travel, if one current collector is provided, or if the current collectors (preferably each) are mounted on the rolling adapter so it can move about a joint axis running orthogonal to the direction of travel, if multiple current collectors are provided, tilting and jamming of the current collector(s) with the conductor track when removing the rolling adapter can be prevented. In addition, during the pivoting movement of the rolling adapter to be removed and a resulting tilting movement of the current collector(s) can be achieved, which facilitates handling when removing the rolling adapter. Furthermore, frequent replacement of rolling adapters hardly leads to any wear on the current collector(s) and the conductor track section(s).

[0120] In addition, a tilting movement of the pantograph(s) as it moves along the rail network enables reliable electrical contact to the conductor track section(s) of the electrical conductor track.

[0121] A clear path along the overhead conveyor for removing the rolling adapter to be removed can correspond to the height of the rolling adapter to allow pivoting. This ensures that the clear path is just large enough to allow pivoting of the rolling adapter into the removal orientation.

[0122] A clearable path along the overhead conveyor device for removing the rolling adapter to be removed can exceed the height of the rolling adapter by a factor greater than 1, in particular a factor between 1.5 and 2. This creates a particularly large clearance fit, which can ensure that (for example by an operator) on the one hand a safe swiveling and on the other hand a safe lateral removal of the rolling adapter can be carried out.The object is also achieved by a storage system for picking stored goods, comprising a loading station for loading hanging bags with stored goods, a storage area for storing hanging bags with stored goods, a packing station for unloading the hanging bags and packing the load goods into shipping packages, and an overhead conveyor device described herein which connects the loading station, the storage area and the packing station, and / or an overhead conveyor device described herein which is arranged in the storage area.

[0123] This means that warehouse goods can be transported, sorted and picked automatically, achieving the advantages mentioned above.

[0124] It is an object of the present invention to provide a method for easily adding rolling adapters to an overhead conveyor device and a corresponding overhead conveyor device.

[0125] The object is achieved by a method for adding a rolling adapter, which is movable along a suspended conveyor device in a direction of travel, to the suspended conveyor device with a plurality of rolling adapters for transporting hanging bags, which are designed to receive stored goods, wherein the suspended conveyor device comprises a rail network with a track and a power supply system with an electrical conductor track, which conductor track runs at a distance from the track, the rolling adapters each comprise a height axis, a drive device with a driven wheel and a power supply with a current collector unit, which power supply is connected to the drive device for driving the driven wheel, and the rolling adapters each roll over the driven wheel on the track of the rail network and are electrically contacted with the conductor track via the current collector unit, comprising the steps

[0126] Inserting a rolling adapter to be added via an access area by a sideways movement of the rolling adapter to be added transversely to the direction of travel and in an insertion orientation of the rolling adapter in which the vertical axis of the rolling adapter runs between the track and the conductor track,

[0127] Placing the rolling adapter to be added, especially with the driven wheel, on the roadway, and

[0128] Pivoting the rolling adapter to be added about a pivot axis relative to the track from the insertion orientation into a use orientation in which the height axis of the rolling adapter forms an angle between 60° and 120°, preferably 90°, with the track, wherein during the pivoting movement of the rolling adapter from the insertion orientation into the use orientation an electrical contact is established between the current collector unit and the conductor track.

[0129] The object is also achieved by a suspended conveyor device, in particular for carrying out the above-mentioned method for adding a rolling adapter, comprising a rail network with a track, a power supply system with an electrical conductor track, which conductor track runs at a distance from the track,

[0130] Hanging bags for storing goods, and

[0131] Rolling adapters for transporting the hanging bags, wherein the rolling adapters are movable in a direction of travel along the overhead conveyor device, which rolling adapters each have a length measured in the direction of travel, a height axis running orthogonally to the direction of travel, a drive device with a driven wheel and a power supply with a current collector unit, which power supply is connected to the drive device, and which rolling adapters each roll over the driven wheel on the track of the rail network and can be electrically contacted with the conductor track via the current collector unit, wherein a rolling adapter for adding to the overhead conveyor device can be placed on the track, in particular with the driven wheel, and can be rotated about a pivot axis relative to the track from an insertion orientation, in which the height axis of the rolling adapter runs between the track and the conductor track, into a use orientation,in which the vertical axis of the rolling adapter forms an angle of between 60° and 120°, preferably 90°, with the track, wherein during the pivoting movement of the rolling adapter from the insertion orientation to the use orientation, an electrical contact can be established between the current collector unit and the conductor track, and the distance between the conductor track and the track is greater than the length of the rolling adapter to be added, wherein the distance defines an access area, so that in the insertion orientation, the rolling adapter to be added can be inserted onto the overhead conveyor device via the access area by a lateral movement running transversely to the direction of travel.

[0132] It should be noted at this point that, according to the invention, the roller adapters are designed for transporting hanging bags. However, this is by no means limiting. Rather, the roller adapters are equally designed for transporting hanging garments hung on a coat hanger. For example, the hanging garment could be a suit, a business suit, a jacket, or a blazer.

[0133] Preferably, the electrical conductor track of the power supply system runs parallel to the roadway at a (at least approximately) constant distance. This enables a reliable power supply and eliminates the need to compensate for variable distances between the conductor track and the electrical conductor track.

[0134] Since the rolling adapters are supplied with electrical power via the power supply system, an energy storage device (e.g., an accumulator) on the rolling adapter is no longer required. In other words, the drive energy is provided by the power supply system.

[0135] The rolling adapters can be moved semi-autonomously or autonomously along the overhead conveyor.

[0136] In other words, the rolling adapters each have their own drive, and they can be moved independently (decoupled) on the rail network. The overhead conveyor system does not require an additional external drive device that simultaneously applies a driving force to the rolling adapters, as is the case with drag chains, for example, in the prior art. The rolling adapters can also be moved at different speeds.

[0137] Since the overhead conveyor system does not require an additional external drive device, the rolling adapters are particularly easy to access and can be removed from the overhead conveyor system with ease. Adding a rolling adapter only requires the steps of inserting the added rolling adapter and pivoting it. The rolling adapter can be added, for example, after performing (planned) maintenance work on a rolling adapter and / or the rail network, particularly on the track and / or electrical conductors.

[0138] However, the addition can be made after a defect on a rolling adapter has been rectified and / or to replace wearing parts and / or to measure parameters and / or to test the functionality of a rolling adapter.

[0139] It should be noted that a single roller adapter or a plurality of roller adapters can be added to the overhead conveyor as required.

[0140] The rolling adapter is used to add to the overhead conveyor device around a pivot axis from the insertion orientation to the use orientation.

[0141] In its intended use, the vertical axis of the rolling adapter forms an angle between 60° and 120°, preferably 90°, with the track. This ensures stable support of the rolling adapter via the driven wheel on the rail network, even during dynamic travel movements.

[0142] In the insertion orientation, the rolling adapter is pivoted relative to the track so that the vertical axis runs (essentially) between the track and the conductor track. The vertical axis does not necessarily have to be between the track and the conductor track, but can intersect the track and / or the conductor track. Inserting the rolling adapter to be added before pivoting it into the use orientation can prove particularly advantageous if the vertical axis runs (essentially) parallel to the direction of travel.

[0143] The pivoting movement of the rolling adapter is limited by the distance between the track and the conductor track, which defines the extent of the access area, and the length of the rolling adapter. Therefore, the position of the vertical axis relative to the track and / or conductor track results from the geometric conditions during insertion.

[0144] In any case, the extent of the access area is dimensioned such that the roll adapter to be added can be inserted across the access area by a lateral movement of the roll adapter to be added transversely to the direction of travel. In other words, the extent of the access area is greater than the height of the roll adapter. Since the roll adapter to be added can be inserted laterally onto the overhead conveyor system, in particular onto the rail network, it is possible to add a roll adapter to virtually any section of the rail network. It is not necessary to insert the roll adapter to be added into a specially configured section of the rail network.

[0145] Preferably, the rolling adapter is pivoted from the insertion orientation to the use orientation by applying a mechanical force to the rolling adapter. This ensures quick and safe pivoting. The mechanical force can be applied by an operator or a mechanical actuator, for example, an electrically operated pivot drive.

[0146] A hanging pocket can be attached to the added rolling adapter, with the hanging pocket being attached after the added rolling adapter has been pivoted. The attachment can be done manually by an operator or by a mechanical actuator, such as a robot.

[0147] A procedural step may be provided

[0148] Creating a free path before and / or after the rolling adapter to be added along the overhead conveyor before the insertion step.

[0149] According to a possible embodiment, the generation of the free path along the overhead conveyor device before and / or after the rolling adapter to be added along the overhead conveyor device can comprise the steps

[0150] Determination of a blockage section based on a length of the free path through the control device,

[0151] Detection of a rolling adapter arranged before and / or after the rolling adapter to be added on the overhead conveyor in the blocking section by the control device, and

[0152] Control of the detected rolling adapter arranged before and / or after the rolling adapter to be added on the overhead conveyor device in the blocking section by actuating the drive device in such a way that the detected rolling adapter is moved out of the blocking section.

[0153] If a rolling adapter blocks the insertion and pivoting movement of the rolling adapter to be added, a free path is created. According to this embodiment, a rolling adapter in the blocking section is detected by the control device and defined as the detected rolling adapter. The detected rolling adapter can be positioned in front of the rolling adapter to be added or after the rolling adapter to be added in the direction of travel. If multiple rolling adapters are detected in the blocking section by the control device, these are defined as detected rolling adapters. The detected rolling adapters can be positioned in front of the rolling adapter to be added or after the rolling adapter to be added in the direction of travel, or in front of the rolling adapter to be added and after the roll adapter to be added in the direction of travel.

[0154] To create the free path, the detected rolling adapter(s) are moved out of the blocking section, creating sufficient space to allow the unobstructed insertion and pivoting of the rolling adapter to be added. If multiple rolling adapters are added, the free path is correspondingly longer than if only one rolling adapter is added.

[0155] According to this embodiment, it is advantageous that the detected rolling adapter is moved out of the blocking section by controlling the drive device of the detected rolling adapter or the detected rolling adapters are moved out of the blocking section by controlling the drive devices of the detected rolling adapters.

[0156] The free path is therefore generated by automatically moving out the recognized rolling adapter or the recognized rolling adapters.

[0157] According to a possible embodiment, the creation of the free path along the overhead conveyor device before and / or after the rolling adapter to be added along the overhead conveyor device can comprise the step

[0158] Applying a mechanical force to a rolling adapter arranged in front of the rolling adapter to be added on the overhead conveyor device in such a way that the rolling adapter is moved out of a blockage section which is predetermined based on a length of the free path, and / or

[0159] Applying a mechanical force to a roller adapter arranged after the roller adapter to be added on the overhead conveyor such that the roller adapter is moved out of a blocking section, which is specified based on the length of the free path. According to this embodiment, a free path is also created when a roller adapter blocks the insertion and pivoting movement of the roller adapter to be added.

[0160] According to this design, a rolling adapter in the blocking section is optically detected, for example, by an operator or a camera system, and defined as a detected rolling adapter. The detected rolling adapter can be positioned in the direction of travel before or after the rolling adapter to be added. If multiple rolling adapters are detected in the blocking section, they are defined as detected rolling adapters. The detected rolling adapters can be positioned in the direction of travel before or after the rolling adapter to be added, or in the direction of travel before and after the rolling adapter to be added.

[0161] To create the free path, the detected rolling adapter(s) are subjected to a mechanical force and moved out of the blocking section, creating sufficient space to allow the unhindered insertion and pivoting of the rolling adapter to be added. If multiple rolling adapters are added, the free path is correspondingly longer than if only one rolling adapter is added.

[0162] The mechanical force can be exerted by an operator.

[0163] The control device may be configured to receive position data of the detected rolling adapter while the rolling adapter is moved out of the blocking section.

[0164] The creation of the free path along the overhead conveyor device before and / or after the rolling adapter to be added along the overhead conveyor device may comprise the following step:

[0165] Determination of position data of the detected rolling adapter during and / or after the rolling adapter is moved out of the blocking section and provision of the position data to a control device.

[0166] Preferably, the central control device can carry out the said method step.

[0167] By providing the position data, it can be ensured, as described above, that the position of the rolling adapter moved out of the blocking section or the positions of the rolling adapters moved out of the blocking section is or are known to the (central) control device. The pivoting of the rolling adapter to be added can take place about a pivot axis running orthogonal to the direction of travel. This means that the pivoting takes place in or against the direction of travel, which makes the pivoting process of the rolling adapter from the insertion orientation to the use orientation particularly simple. Establishing the electrical contact between the current collector unit and the conductor track is particularly reliable, and inserting the rolling adapter to be added via the access area is also easy, since the insertion takes place by a sideways movement of the rolling adapter to be added that runs transversely to the direction of travel.

[0168] The pivot axis is preferably formed by a wheel axis or a wheel support line of a wheel, preferably the driven wheel.

[0169] Preferably, the rolling adapters each have only one wheel, which is designed as a driven wheel and forms a wheel axle.

[0170] The drive device may comprise a plurality of wheels rolling on the roadway, wherein at least one of the wheels forms the driven wheel.

[0171] Preferably, the rolling adapters each have only two wheels that form a wheel axle.

[0172] One of the wheels can be driven and one of the wheels can be non-driven, which allows cornering to be carried out in a way that reduces wear.

[0173] Preferably, the rolling adapters each have only one wheel axle, which facilitates the pivoting of a rolling adapter to be added.

[0174] Alternatively, both wheels can be driven. For this purpose, the driven wheels can each be coupled to a drive motor. If both wheels are driven, the rolling adapter can be steered by differential speed control of the wheels. Therefore, in this design, the drive motors form the lateral dynamic control described above. Each drive wheel is driven at a different speed to rotate the rolling adapter around its vertical axis. To move forward or backward, however, both drive motors are driven at the same speed. In this design, the drive motors also form the traction drive.

[0175] Preferably, the rolling adapters can each have two wheels sharing the same wheel axle, while the rolling adapter forms only one wheel axle. According to a preferred embodiment, the pivot axis is formed by a wheel axle or a wheel support line of the driven wheel. As described above, the wheel axle can also be formed by a wheel axle of two wheels, with at least one of the wheels being driven.

[0176] The pivot axis can run orthogonally to the direction of travel and is preferably formed by a wheel axle of one wheel of the rolling adapter, preferably the driven wheel, or by a wheel axle of two wheels of the rolling adapter (at least one of the wheels is a driven wheel). If the wheel axle is used as a pivot axis in the aforementioned designs, the rolling adapter can be easily pivoted while the wheel rests on the roadway or while the wheels rest on the roadway. This enables particularly simple and smooth pivoting.

[0177] A wheel support line of one wheel of the rolling adapter, preferably the driven wheel, or a wheel support line of two wheels of the rolling adapter can also be used as the pivot axis. This enables particularly simple and smooth pivoting.

[0178] If the pantograph is mounted on the rolling adapter so it can move about a joint axis running orthogonal to the direction of travel, if one pantograph is provided, or if the pantographs (preferably each) are mounted on the rolling adapter so it can move about a joint axis running orthogonal to the direction of travel, if multiple pantographs are provided, tilting and jamming of the pantograph(s) with the conductor track can be prevented when the rolling adapter is added. In addition, during the pivoting movement of the rolling adapter to be added and a resulting tilting movement of the pantograph(s) can be achieved, which facilitates handling when adding the rolling adapter. Furthermore, frequent replacement of the rolling adapters leads to hardly any wear on the pantograph(s) and the conductor track section(s).

[0179] In addition, a tilting movement of the pantograph(s) as it moves along the rail network enables reliable electrical contact to the conductor track section(s) of the electrical conductor track.

[0180] It should be noted here that the following hanging bag storage system can also be referred to as a storage system, the loading station also as a transfer point, the packing station also as an unloading station, the rail network also as a network, the roadway also as a (stationary) traction layer, the electrically conductive conductor track also as a (stationary) energy layer, and / or the following storage area can also be referred to as a level. Likewise, the following distance between the conductor track and the roadway can also be referred to as the clear height and / or the access area also as the free space.

Before the invention is described in detail, it should be noted that it is not limited to the respective components of the device or the respective method steps, since these components and methods can vary. The terms used herein are intended solely to describe particular embodiments and are not used in a restrictive manner. Furthermore, when the singular or indefinite articles are used in the description or claims, this also refers to the plurality of these elements, unless the overall context clearly indicates otherwise.

[0192] Figure 1 shows a storage system 1 (can also be referred to as hanging pocket storage) in a schematic three-dimensional view from an oblique side front top.

[0193] The storage system 1 serves for picking stored goods 3 and comprises a storage area 9, 13 (can also be referred to as a level) for storing hanging bags 5 with stored goods 3. A plurality of storage areas 9, 13 arranged vertically one above the other can also be provided. In Figure 1, a total of four storage areas 9, 13 are provided by way of example, whereby, for reasons of clarity, only a first storage area 9 and a second storage area 13 are provided with reference numerals.

[0194] If a plurality of storage areas 9, 13 is provided in the storage system 1, the plurality of storage areas 9, 13 preferably each have a transfer buffer 7, 11, as shown in Figure 1, wherein, for reasons of clarity, only a first transfer buffer 7 and a second transfer buffer 11 are provided with reference numerals. The transfer buffers 7, 11 are preferably arranged vertically one above the other, which is symbolized by a dash-dotted line 27. However, it is also conceivable to arrange only at least two of the transfer buffers 7, 11 one above the other and / or to arrange them obliquely to a vertical spatial direction along the line 27.

[0195] If transfer buffers 7, 11 are provided, a vertical conveyor 23, for example a ring conveyor system, can preferably be provided along the imaginary line 27 along which the transfer buffers 7, 11 are arranged. The transfer buffers 7, 11 are advantageously arranged adjacent to the vertical conveyor 23 such that the stored goods 3 can be transferred from the transfer buffers 7, 11 to the vertical conveyor 23 and / or stored from the vertical conveyor 23 into the storage areas 9, 13 or into the transfer buffers 7, 11 of the storage areas 9, 13. The stored goods 3 can be transferred directly to the vertical conveyor 23 or, located in a hanging pocket 5, into the vertical conveyor system 23. The storage system 1 further comprises a loading station 53 (can also be referred to as a transfer point) for loading hanging pockets 5 with storage goods 3. Preferably, each hanging pocket 5 is loaded with only one of the storage goods 3.However, loading a hanging bag 5 with several storage goods 3 is also conceivable, provided that these can be accommodated in the corresponding hanging bag 5.

[0196] Optionally, the storage goods 3 are buffered in the loading station 53. Hanging pockets 5 move to the loading station 53, whereupon the hanging pockets 5 are loaded with the (buffered) storage goods 3. Preferably, the hanging pockets move autonomously to a storage location of the storage system 1.

[0197] In addition, the storage system 1 comprises a packing station 55 (can also be referred to as an unloading station) for unloading the hanging pockets 5 and packing the load into shipping packages.

[0198] At the unloading station 55 of the storage system 1, the stored goods 3 can be removed from a vertical conveyor 23 and are available there, preferably in a predetermined or predeterminable sequence 15. It is conceivable for a column of hanging pockets 5 to move from the vertical conveyor 23 into the unloading station 55 in the desired sequence 15, or to be transferred from the vertical conveyor 23 to the unloading station, unloaded there, and then return for further loading. The unloading station 55 can be located inside or outside one of the storage areas 9, 13, preferably in a lowest storage area.

[0199] At least one overhead conveyor device 10 is provided in the storage system 1, which is only roughly indicated in Figures 1 and 3 and is described in more detail schematically starting with Figures 4A, B, and C. The overhead conveyor device 10 can be used to receive, store, sort, and / or retrieve stored goods 3 and can be configured either as a pure storage or sorting device. The overhead conveyor device 10 can, for example, connect the loading station 53 and / or the storage area 9, 13 and / or the packing station 55. An overhead conveyor device 10 can also be arranged in the storage area 9, 13.

[0200] Furthermore, roller adapters 61 for transporting the hanging pockets 5 are provided in the overhead conveyor device 10, wherein the roller adapters are movable in a direction of travel along the overhead conveyor device 10. Figure 2 shows a schematic side view of a roller adapter 61 with a hanging pocket 5 for the storage system 1 shown in Figure 1. A drive device with at least one driven wheel 57 is provided. The drive energy provided by an energy supply system for the driven wheel 57 is merely indicated in Figure 2 by reference numeral 59.

[0201] Figure 2 shows a hanging pocket 5 containing eager goods 3, which is accommodated in the hanging pocket 5. The eager goods 3 are located within a U-shaped, preferably flexible and / or foldable pocket material of the hanging pocket 5. Loading and / or unloading of the stored goods 3 can occur in particular from above and / or from the side.

[0202] The rolling adapters 61 and associated hanging pockets 5 can be integrated into each other or can be designed in two parts, preferably detachable without destruction.

[0203] The rolling adapter 61 preferably comprises a signal processing unit 620, which communicates with the control device 25. Communication between the control device 25 and the signal processing unit 620 is preferably wireless. Said communication can include control commands, for example, for performing autonomous or semi-autonomous driving maneuvers of the rolling adapter 61. The control device can be used to monitor and control the overhead conveyor device 10.

[0204] The drive device preferably comprises an electric drive which communicates with the signal processing unit 620. The drive can be referred to as a longitudinal dynamics control and is connected to the driven wheel in order to drive it. The drive is designed to set driving states and can, for example, comprise an electric motor. The driving states can, for example, represent stopping and driving forward, preferably: reversing, stopping and driving forward. Particularly preferably, different speeds and / or transient driving states can be set and / or controlled by the drive. It is advantageous if the following driving states can be set and / or controlled: driving forward, reversing, stopping, accelerated forward driving, accelerated reversing, braked forward driving, braked reversing.

[0205] The roll adapter 61 can further comprise a lateral dynamics control system. The lateral dynamics control system can, in particular, comprise electrically controllable steering elements and can establish at least one driving state from the following group: driving straight ahead, turning left, or turning right. The lateral dynamics control system can be part of the drive device.

[0206] It is also conceivable that the hanging pockets 5 are conveyed by means of the vertical conveyor system 23 and unloaded at the unloading station 55 in the desired order and immediately transported back empty to the storage system 1 by means of the vertical conveyor system 23, i.e. without the respective hanging pockets 5 remaining in the unloading station 55 or being available there, for example, in order to travel on to the loading station 53 or to be transported on after unloading.

[0207] Insofar as the terms X-direction, Y-direction and Z-direction are used in this application, this can be understood as a Cartesian coordinate system traveling with the hanging pockets 5 or rolling adapter 61, in particular their drive, wherein the X-direction can characterize a direction of travel, the Y-direction a direction transverse to the direction of travel and, in the case of a planar travel movement, horizontal, and the Z-direction a vertical direction perpendicular to the other axes or vertical axis of the rolling adapter 61 or the hanging pocket 5.

[0208] Figure 3 shows a rough schematic side view of a section of an overhead conveyor device 10. A plurality of the roller adapters 61 shown in Figure 2, including hanging pockets 5, are shown on a rail network 49 of the overhead conveyor device 10. In Figure 3, possible directions of travel of the hanging pockets 5 in the rail network 49 are indicated by a double arrow 51. The rail network 49 is only roughly schematically shown in sections in Figure 3 and is described in more detail in Figure 4. The drive energy provided by an energy supply system for the driven wheel 57 is merely indicated in Figure 3 by the reference numeral 59.

[0209] Figures 4A and 4B each show an exemplary schematic side view of a section of the overhead conveyor device 10 with a rail network 49 with a track 809. The rail network 49 comprises a power supply system with an electrical conductor track 807, which runs at a distance from the track 809. The distance between the electrical conductor track 807 and the track 809 is preferably constant or approximately constant. The track 809 is arranged here in the vertical, or Z-direction, below the electrical conductor track 807. The rail network 49 can have connecting sections and branches such as crossings and / or switches (not shown). The rail network 49 is, for example, mounted, in particular fixed, to a fastening layer 821. The fastening layer 821 can be part of a structure 823, for example a ceiling, that accommodates the storage system 1.However, it is also possible for the fastening layer 821 to form or have its own supporting structure, for example, by means of beams or girders to which the rail network 49 is or can be fastened. Furthermore, it is conceivable for the fastening layer 821 to have a continuous supporting structure and thus be part of the rail network 49, in particular a structural system of the rail network 49. The continuous supporting structure, in turn, can be fixed, supported, and / or firmly connected to the structure 823 by means of suitable fastening means.

[0210] Furthermore, a mounting device 827 can be provided, on which the rail network 49 with the track 809 and the energy supply system with the electrical conductor track 807 are mounted, in particular detachably.

[0211] The mounting device 827 fixed or fixable to the fastening layer 821 in Figure 4A, B can also serve as a bearing for further components of the rail network 49, wherein these further components can be fixed or mounted on the mounting device 827.

[0212] The electrical conductor track 807 is arranged here in the vertical Z direction below the fastening layer 821. It is conceivable to implement the electrical conductor track 807 and the fastening layer 821 as an integral component. The energy supply system with the electrical conductor track 807 serves to provide the drive energy 59 for the rolling adapters 61, in particular for driving and / or braking, preferably for performing autonomous or semi-autonomous driving maneuvers.

[0213] A plurality of roller adapters 61 are provided for transporting hanging bags 5, wherein the plurality of roller adapters 61 are movable in a direction of travel along the hanging conveyor device 10 and are arranged on the rail network 49.

[0214] Preferably, the rail network 49 is designed to be passive, i.e., without any control elements. This means that the rail network 49 does not have any active control elements that influence the transverse dynamics of the rolling adapters 61, on which wheels 61 or contact surfaces can rest transversely to the direction of travel to effect a network-adjustable change of direction, as is known, for example, from conventional adjustable switches.

[0215] The rail network 49 is particularly preferably constructed horizontally or essentially horizontally. By essentially horizontal can be understood here that the rolling adapters 61 traveling on it do not roll away automatically due to gravity when stationary, and can therefore preferably be constructed without a parking brake. In this case, the drive is therefore free of gravity and therefore not gravity-induced. The rolling adapters 61 are preferably set up, programmed and / or designed for autonomous or semi-autonomous travel on the rail network 49. Storage systems 1 with autonomously moving hanging pockets 5 are known and are described, for example, in DE 102018 128 417 A1, so a more detailed description is omitted here. Preferably, a monitoring and control of the overhead conveyor device 10 and, if applicable,of the further storage system 1, in particular for specifying the desired sequence 15 and controlling the vertical conveyor system 23, a control device 25 is provided which exchanges information with the associated functional units.

[0216] The rolling adapters 61 each have a length L measured in the direction of travel. This length represents the extension of the rolling adapters 61 in the direction of travel when in use orientation. Furthermore, the rolling adapters 61 have a height H, which represents the extension of the rolling adapters 61 in the orthogonal direction when in use orientation. The height H and length L are symbolized in Figure 4 by curved brackets.

[0217] As mentioned, the rolling adapters 61 have a drive device with at least one driven wheel 57 and a power supply with a current collector unit 610. The power supply is connected to the drive device and serves to drive the driven wheel 57. The rolling adapters 61 each roll over the driven wheel 57 on the track 809 of the rail network 49, in particular transmitting a driving force or braking force, and can each be electrically contacted with the conductor track 807 via the current collector unit 610, as shown in more detail in Figures 7A, B, C. Thus, a traction drive is formed.

[0218] Figures 7A and B each show a rolling adapter 61 with a length L measured in the direction of travel, a height H orthogonal thereto, and a height axis extending orthogonally to the direction of travel in several states and representations on the rail network 49. The rolling adapter 61 has a head 817, a current collector unit 610, a shaft 819, a hanging pocket holder 815, and a hanging pocket 5 suspended therefrom. A driven wheel 57, which is encompassed by the rolling adapter 61, is also shown.

[0219] In Figure 7A, the vertical axis of the rolling adapter 61 is aligned vertically because the rolling adapter 61 is at a standstill. The driven wheel 57 has a wheel axle 811, is at a standstill, and rests with a wheel support line on the track 809 of the rail network 49. In Figure 7B, the vertical axis of the rolling adapter 61 is slightly inclined due to inertia because the rolling adapter 811 is moving to the left in the direction of travel. The driven wheel 57 rolls on the track 807. During the rolling movement, the wheel 57 rests with its wheel support line on the track 807. The electrical contact between the current collector unit 610 and the conductor track 807 is maintained, thus ensuring the power supply or energy supply for driving the driven wheel 57.For this purpose, it is advantageous if the current collector unit 610 is mounted on a holder via a spring element and / or the current collector unit is mounted on the rolling adapter 61 so as to be movable about an articulated axis 613 running orthogonally to the direction of travel.

[0220] Figure 7C shows the joint axis 613 of the pantograph unit 610 and the wheel axis 811. Furthermore, the rolling adapter center of gravity S61, which is preferably located below the track 809, is shown. Furthermore, the hanging bag center of gravity S5 is shown, and a joint axis is defined by the hanging bag receptacle 815. Thus, a multi-joint construction can be seen, wherein an inclination or rotation about the wheel axis 811 results in a pivoting about the joint axis 613 of the pantograph and about the joint axis defined by the hanging bag receptacle 815. An inclination about the wheel axis 811 can also occur during normal operation of the rolling adapter 61.

[0221] To remove one of several rolling adapters 61 movable along the overhead conveyor device 10 in a direction of travel, the rolling adapter 61 is pivoted about a pivot axis, for example, the wheel axis 811, relative to the track 809 from a use orientation to a removal orientation. The first state illustrated in Figure 4A shows the rolling adapter 61 to be removed in the use orientation; the second state illustrated in Figure 4B shows the rolling adapter 61 to be removed in the removal orientation.

[0222] In the use orientation, the vertical axis of the rolling adapter 61 forms an angle between 60° and 120°, preferably 90°, with the track 809. In the removal orientation, the vertical axis of the rolling adapter 61 runs between the track 809 and the conductor track 807, preferably horizontally and / or parallel to the direction of travel.

[0223] The pivot axis can be orthogonal to the direction of travel and can preferably be formed by a wheel axle 811 of the driven wheel 57.

[0224] After pivoting into the removal orientation and after breaking the electrical contact between the current collector unit 610 and the conductor track 807, the rolling adapter 61 to be removed is removed via an access area 805 (free space) by a sideways movement of the rolling adapter 61 to be removed, running transversely to the direction of travel. The access area 805 can be delimited on both sides in the direction of travel of the rolling adapter 61 by a mounting device 827.

[0225] Figures 5A and B each show a schematic cross-section of the rolling adapter 61 to be removed, shown in Figures 4A and B, on the overhead conveyor device 10 with further optional details in two different positions (states). Fig. 5A shows the first state, i.e., the rolling adapter 61 to be removed in the use orientation, and Fig. 5B shows the second state, i.e., the rolling adapter 61 to be removed in the removal orientation, wherein removal of the rolling adapter 61 has already been initiated via an access area 805 by a lateral movement running transversely to the direction of travel.

[0226] The distance (clear height LH) between the conductor track 807 and the track 809 is greater than the length L of the rolling adapter 61 to be removed. This distance defines an access area 805 (free space) so that in the removal orientation, the rolling adapter 61 to be removed can be removed from the overhead conveyor device 10 via the access area 805 by a sideways movement running transversely to the direction of travel, as shown by the fourth arrow 837 in Figure 5B.

[0227] The roadway 809 shown in Figures 5A, B has two roadway sections arranged parallel to one another at a distance A, and driving surfaces (traction surfaces) 813 formed on the roadway sections. The drive device of the rolling adapter 61 shown here comprises a plurality of wheels 57, with at least one of the wheels forming the driven wheel 57. One of the wheels 57 can roll on the driving surface 813 of one of the roadway sections, and another of the wheels 57 can roll on the driving surface 813 of another of the roadway sections, as shown in Figures 5A, B.

[0228] The rolling adapter 61 to be removed comprises a shaft 819, which, in the orientation of use, is arranged between the roadway sections and protrudes downward from a gap between the roadway sections. At least one lower shaft section protruding downward from the gap forms a maximum width B measured orthogonally to the direction of travel, wherein the distance A between the roadway sections is greater than the maximum width B.

[0229] As shown in Figure 4B, a free path 803 can be created before and / or after the rolling adapter 61 to be removed along the overhead conveyor device 10 before the pivoting step. For this purpose, a control device 25 can be used to determine a blocking section based on a length of the free path 803 along the overhead conveyor device before and / or after the rolling adapter 61 to be removed. Furthermore, one or more rolling adapters 61 arranged before or after the rolling adapter 61 to be removed on the overhead conveyor device in the blocking section are detected. In Figure 4, four rolling adapters 61 to the left (i.e., in front of) and one rolling adapter 61 to the right (i.e., after) the rolling adapter 61 to be removed are detected and moved out of the blocking section, which is indicated in Figure 4B by a third arrow 833.

[0230] These detected rolling adapters 61 can be controlled by the control device 25 by actuating their drive mechanism such that they are moved out of the blocking section. Likewise, the control device 25 prevents further rolling adapters from moving into the blocking section.

[0231] Instead of controlling the respective rolling adapters 61 to move out of the blocking section, the said rolling adapters 61 can also be subjected to an external mechanical force in order to move the said rolling adapters 61 out of the blocking section.

[0232] Of course, a first part of the rolling adapters 61 located in the blocking section can also be controlled and a second part of the rolling adapters 61 located in the blocking section can be subjected to a mechanical force in order to move them out of the blocking section.

[0233] The electrical coupling between the current collector unit 610 and the conductor track 807 of the rolling adapters 61 to be relocated can be maintained during the relocation.

[0234] During and / or after the respective rolling adapters 61 are moved out of the blocking section, position data of the respective rolling adapters 61 can be determined and provided to a control device 25. Although the control device 25 is shown centrally in Figure 1, it can also be arranged, for example, on the rolling adapter 61.

[0235] The clearable path 803 along the overhead conveyor device for removing the rolling adapter 61 to be removed exceeds a height H of the rolling adapter 61 by a factor greater than 1, in particular a factor between 1.5 and 2, in order to be able to remove the rolling adapter 61 conveniently and collision-free from the rail network 49. The rolling adapter 61, more precisely its shaft 819 (and optionally its head 817) can be pivoted into the clear path 803. The pivoting takes place about a pivot axis perpendicular to the direction of travel of the rolling adapter 61, preferably a wheel axis 811 of the rolling adapter 61 or a support point of the wheels 57 on the rail network 49, more precisely the track, preferably the traction surfaces 813, of the rail network 49. The pivoting movement of the selected rolling adapter 61 is indicated in Figure 4B by a curved arrow 835.It is approximately 90 degrees and can be rotated either counterclockwise or clockwise from a resting position or from a position suspended in the rail network 49 and can be accomplished by manual gripping and turning or, preferably, by means of a mechanization such as a robot.

[0236] The rolling adapters 61 each have an optional head 817, as shown in Figures 5A, B, 7A, B, C, 8A, B, C, and 9, wherein the current collector unit 610 is preferably arranged on the head 817.

[0237] The current collector unit 610 can also have multiple current collectors (not shown). Preferably, the electrical conductor track 807 comprises multiple electrically insulated conductor track sections, wherein, in the orientation of use of the rolling adapter 61, the current collectors and the conductor track sections each form an electrical contact. If multiple current collectors are provided, they can each be mounted on a holder via a spring element and / or the current collectors can each be mounted on the rolling adapter 61 so as to be movable about a joint axis 613 extending orthogonally to the direction of travel.

[0238] Figure 8A, B, C shows the pivoting of the rolling adapter 61 to be removed from the use orientation to the removal orientation in three intermediate shots.

[0239] In Figure 8 A, the pivoting of the rolling adapter 61 has already begun, whereby the electrical contact between the current collector unit and the conductor track has not yet been interrupted.

[0240] In Figure 8B, the pivoting of the rolling adapter 61 to be removed has progressed further. The electrical contact between the current collector unit 610 and the conductor track 807 has already been interrupted.

[0241] In Figure 8C, the rolling adapter 61 is already in the removal orientation. The vertical axis of the rolling adapter 61 now runs between the track 809 and the conductor track, here horizontally. The pivoting of the rolling adapter 61 into the removal orientation can be achieved by manually applying a mechanical force to the rolling adapter 61.

[0242] Pivoting the selected rolling adapter 61 about a pivot axis or about, preferably a wheel axis 811, of the rolling adapter 61 into the removal orientation.

[0243] In the following, with reference to the drawing, in particular Figure 6, which shows a flow chart, the method for removing one of several rolling adapters 61 which are movable along a hanging conveyor device 10 in a direction of travel, preferably semi-autonomously or autonomously, for transporting hanging bags 5 which are designed to receive stored goods 3 is described.

[0244] In a first optional step 839, a rolling adapter 61 is selected from the plurality of rolling adapters 61, which selects (determines) the rolling adapter 61 to be removed, which is indicated in Figure 4A in the first state by means of a first arrow 829.

[0245] If the rolling adapter 61 to be removed is provided with a hanging pocket 5 coupled to the rolling adapter 61, an optional decoupling of the hanging pocket 5 can be performed in a second step 841, which occurs before the rolling adapter 61 to be removed is pivoted. The decoupling, for example, a separation and / or detachment of the hanging pocket 5, is symbolized by a second arrow 831, in Figure 4A in the first state.

[0246] The decoupling is preferably non-destructive, repeatable, and reversible. This can preferably be done by manually grasping and releasing the hanging pocket 5 from a hanging pocket receptacle 815, for example, an eyelet or hook 815, of the shaft 819. The hanging pockets 5 can also have a corresponding hook or eyelet.

[0247] The method may comprise, as a third, optional additional step 843, generating a free path 803 before and / or after the rolling adapter 61 to be removed along the (travel path of the) overhead conveyor device 10 before the pivoting step, as already explained above.

[0248] As a fourth step 845, the rolling adapter 61 is pivoted about a pivot axis relative to the track 809 from a use orientation to the removal orientation for removal from the overhead conveyor device 10, as also explained in detail above.

[0249] For the actual removal, in a fifth step 847, the selected rolling adapter 61 is guided out of the rail network 49 through the free space 805 or the clear height LH between the electrical conductor track 807 and the track 809 of the rail network 49 by a lateral movement running transversely to the direction of travel, as shown in Figures 4B and 5B in the second state by the fourth arrow 837. In particular, at least a minimal lifting of the rolling adapter 61 (in particular in the vertical direction away from the track 809) can also take place.

[0250] The shaft 819 is pivoted upward through the longitudinal recess from the normal orientation into a removal orientation, preferably by 90°, into the free space 805 between the electrical conductor track 807 and the track 809. The rolling adapter 61 is oriented in the removal orientation such that its rolling adapter length L (i.e., the maximum length of the rolling adapter in the use orientation) is vertical and its rolling adapter height (i.e., the total height of the rolling adapter in the use orientation) is, in particular, horizontal. The rail network has, at least in sections, a lateral opening in the area of ​​the free space 805 with a horizontal opening length equal to or greater than the rolling adapter height. The pivoted rolling adapter 61 is removed through the opening from the free space 805.

[0251] Figures 9A and B each depict advantageous embodiments of the current collector unit 610 of the rolling adapter 61. The current collector comprises a sliding body with a front end region in the direction of travel and a rear end region in the direction of travel, wherein the sliding body forms a front clearance 611 in the front end region on an upper side facing the conductor track section and a rear clearance 611 in the rear end region on an upper side facing the conductor track section. The formation of a front and / or rear clearance 611 ensures that the respective sliding bodies do not tilt or jam with the electrical conductor track 807 when pivoting, removing, and reinserting the rolling adapter 61. Furthermore, the clearance allows any transitions or joints in or on the rail network 49 to be more effectively covered.It is of course also possible to provide only a front clearance 611 or a rear clearance 611.

[0252] The clearance 611 can be formed by a rounding of the front / rear end region, as shown in Figure 9B. This ensures electrical contact in every position of the rolling adapter. Alternatively, the clearance 611 can also be formed by a bevel of the front / rear end region, as shown in Figure 9A. Such a clearance 611 is particularly easy to produce. In addition, the clearance 611 of the grinding bodies can each form an engagement surface 612 facing the conductor track section, which is arranged and designed in such a way that a sliding movement between the grinding body and the conductor track section is enabled during the pivoting movement of the rolling adapter 61 from the use orientation to the removal orientation.

[0253] In the above explanations, the removal of a number of rolling adapters 61 was described, while in Figs. 10A and 10B the addition of a number of rolling adapters 61 is described. The same reference numerals are used for the same parts.

[0254] Fig. 10A particularly shows the insertion of a rolling adapter 61 and the rolling adapter 61 to be added in an insertion orientation. Fig. 10B particularly shows the pivoting of the rolling adapter 61 according to Fig. 10A and the rolling adapter 61 to be added in a use orientation.

[0255] In particular, with regard to the design and / or arrangement of the track 809, the rolling adapter 61, the drive device of the rolling adapter 61, the current collector unit 610, the grinding body(s) of the current collector unit 610, the mounting device 827 and / or the control device 25, reference is made to the above description and, for example, claims 2, 3, 11, 12, 16 to 19, 24 to 29 and 33 and will not be repeated here.

[0256] It should be noted that adding a number of rolling adapters 61 is basically equivalent to removing a number of rolling adapters 61, only in the reverse order of the process steps.

[0257] Accordingly, the following method results for adding a rolling adapter 61 to an overhead conveyor device 10 having a plurality of rolling adapters 61 movable in a direction of travel for transporting hanging bags 5.

[0289] Preferably, the current collector unit 610 can comprise a plurality of current collectors, as described above, each of which has a grinding element. A front and / or rear clearance of the grinding elements each form an engagement surface 612 facing the conductor track section, which engagement surface is arranged and configured in such a way that a sliding movement between the grinding elements and the conductor track sections is enabled during the pivoting movement of the rolling adapter 61 from the insertion orientation to the use orientation.

[0290] The overhead conveyor device 10 can also additionally provide a control device 25 which is designed to

[0297] Figure 1 shows a schematic three-dimensional view from the side front and top of a hanging pocket storage unit 1.

[0298] The hanging pocket storage system 1 has at least two levels 9, 13, here a total of four, with a first level 9 and a second level 13 being provided with reference numerals, for example. More or fewer levels are conceivable, for example, 10 levels or more, arranged vertically one above the other.

[0299] Each of the levels 9, 13 of the hanging pocket storage 1 has a transfer buffer 7, 11, of which only a first transfer buffer 7 and a second transfer buffer 11 are provided with reference numerals.

[0300] The hanging pocket storage system 1 serves for receiving, storing, sorting, and / or retrieving stored goods 3, optionally as a pure storage or sorting device. The transfer buffers 7, 11 are preferably arranged vertically one above the other, as symbolized by a line 27. However, it is also conceivable to arrange at least two of the transfer buffers 7, 11 one above the other and / or to arrange them at an angle to a vertical spatial direction along the line 27.

[0301] A ring conveyor system 23, preferably a plurality of such, also runs along the imaginary line 27 along which the transfer buffers 7, 11 are arranged. The transfer buffers 7, 11 are arranged adjacent to the ring conveyor system 23 in such a way that the stored goods 3 can be transferred from them into the ring conveyor system 23 and / or stored from there into the levels 9, 13 or the transfer buffers 7, 11 of the levels 9, 13.

[0302] According to one exemplary embodiment, the stored goods 3 are transferred directly to the ring conveyor system 23. Preferably, the stored goods 3 are transferred to the ring conveyor system 23 while located in a hanging pocket 5. Particularly preferably, the entire hanging pocket 5 is driven autonomously, in particular by means of a traveling electric drive, controlled, and / or moved before provision, during provision, and / or transfer of the hanging pocket 5. The movement is preferably carried out by means of electric drives, in particular without drag chains and / or carriers. For this purpose, the hanging pocket warehouse 1 is designed, for example, at least partially or entirely, without drag chains and / or carriers, preferably at least within levels 9, 13.

[0303] For this purpose, the hanging pocket storage system 1 comprises a network 49, for example, a rail network, preferably with connecting sections and branches such as crossings and / or switches. This is preferably a grid with straight rails connected to one another by crossings and / or switches, for example, with rectangular meshes.

[0304] In order to store the stored goods 3 in the hanging bag warehouse, this preferably has a transfer point 53, via which the individual stored goods are transferred into individual hanging bags 5. Preferably, only one of the stored goods 3 is transferred per hanging bag 5. However, a transfer of several stored goods 3 into a hanging bag 5 is also conceivable, provided that they can be accommodated in the corresponding hanging bag 5. In the transfer point 53, the stored goods 3 can optionally be buffered and transferred directly into the hanging bags 5, which for this purpose approach the transfer point 53 and then travel on, preferably autonomously, to a storage location in the hanging bag warehouse 1.

[0305] At an optional unloading station 55 of the hanging bag storage system 1, the stored goods 3 can be removed from the ring conveyor system 23 and are available there, preferably in a predetermined or predeterminable sequence 15. It is conceivable for a column of hanging bags 5 to move from the ring conveyor system 23 into the unloading station 55 in the desired sequence 15, or to be transferred from the ring conveyor system 23 to it, unloaded there, and then return for further loading. The unloading station 55 can be arranged inside or outside one of the levels 9, 13, preferably on a lowest level.

[0306] Alternatively, however, it is also conceivable that the hanging pockets 5 are conveyed by means of the ring conveyor system 23 and unloaded at the unloading station 55 in the desired order and immediately transported back empty to the hanging pocket storage 1 by means of the ring conveyor system 23, i.e. without the respective hanging pockets 5 remaining in the unloading station or being available there, for example in order to continue to travel or be transported further to the transfer point 53 after unloading.

[0307] Particularly preferably, the hanging pockets 5 are designed so that they travel autonomously through the network 49. Hanging pocket warehouses 1 with autonomously moving hanging pockets 5 are known and are described, for example, in DE10 2018 128 417 A1, so a more detailed description is omitted here. Preferably, a control device 25 is provided for monitoring and controlling the hanging pocket warehouse 1, in particular for specifying the desired sequence 15 and controlling the ring conveyor system 23, which control device exchanges information with the functional units of the hanging pocket warehouse 1. Figure 2 shows a schematic side view of such a hanging pocket 5 for the hanging pocket warehouse 1 shown in Figure 1 and

[0308] Figure 3 is a three-dimensional view of several of the hanging pockets 5 shown in Figure 2, suspended in the net 49 designed, for example, as a rail network.

[0309] For this purpose, wheels 57 are provided on a rolling adapter 61, which are preferably driven by a drive energy, merely indicated by reference numeral 59, and a drive utilizing this energy. Preferably, the energy layer 807 is an electrical conductor track for providing electrical energy to the rolling adapter 61, wherein the rolling adapter 61 has a, preferably spring-loaded, current collector for receiving electrical energy via an electrical contact from the electrical conductor track. Also conceivable is a conveyor chain circulating in the energy-conducting layer 807 and / or mechanical conveyor means for transmitting mechanical energy to and from the rolling adapter 61.The hanging pockets 5 can be designed in two parts and comprise a rolling adapter 61 and a pocket material suspended or hung thereon, in particular in a manner that can be removed non-destructively, in particular a sagging and / or foldable material in which a stored item 3 can be accommodated. In Figure 3, a double arrow 51 indicates a possible direction of movement of the hanging pockets 5 in the net 49. The hanging pockets 5, in particular their rolling adapter 61, are configured, programmed, and / or designed for autonomous or semi-autonomous travel on the net 49. For this purpose, they, in particular the rolling adapter 61, can have their own drive, preferably an electric drive, and each have their own longitudinal and lateral dynamics control.

[0310] By means of the longitudinal dynamics control, at least two driving states from the following group can preferably be set: stopping and driving forward. Preferably from the group: reversing, stopping and driving forward. Particular preference is given to setting different speeds and / or transient driving states, in particular in combination with a longitudinal acceleration control / regulation. In a particular embodiment, the longitudinal dynamics control can have an electric motor as its own drive and can set at least one driving state from the group: “driving forward, reversing, stopping, accelerated forward, accelerated reversing, braked forward, braked reversing”. The lateral dynamics control can in particular have electrically controllable steering elements and can set at least one driving state from the group: driving straight ahead, turning left, turning right.Preferably, the network 49 can be designed passively, i.e., without control elements. Control element-free can be understood as meaning that the network 49 does not have any active control elements that influence the transverse dynamics of the rolling adapters 61 or the hanging pockets 5, on which wheels or contact surfaces can rest transversely to the direction of travel to effect a network-adjustable change of direction, as is known, for example, from conventional adjustable switches.

[0311] Particularly preferably, the net 49 is constructed horizontally or substantially horizontally. "Substantially horizontal" here means that the rolling adapters 61 traveling thereon do not roll away automatically due to gravity when stationary, thus preferably being constructed without a parking brake. In this case, the drive is therefore gravity-free, and thus not gravity-induced. Furthermore, the drive can be designed as an electric drive, whereby the longitudinal dynamics control or the drive can be drag-chain-free, gravity-free, and / or driver-free.

[0312] Figure 2 shows the hanging pocket 5 with the stored goods 3 held therein. The stored goods 3 are located within a U-shaped suspended material, particularly a flexible material. Loading and unloading can occur, in particular, from above and / or from the side.

[0313] Insofar as the terms X-direction, Y-direction and Z-direction are used in this application, this can be understood as a Cartesian coordinate system traveling with the hanging pockets 5 or rolling adapter 61, in particular their drive, wherein the X-direction can characterize a direction of travel, the Y-direction a direction transverse to the direction of travel and, in the case of a planar travel movement, horizontal, and the Z-direction a vertical direction perpendicular to the other axes or vertical axis of the rolling adapter 61 or the hanging pocket 5.

[0314] Figures 4A, B show a schematic side view of the net 49 of the hanging pocket storage system 1 outlined in the previous figures, filled with the rolling adapters 61, in two states to illustrate a removal process for one of the rolling adapters 61. Figures 5A, B show a schematic cross-section of the net 49 shown in Figures 4A, B, also in both states. The process of removing the rolling adapter 61 is explained in more detail below with reference to Figures 4A, B and 5A, B.

[0315] A bearing arrangement 801 can be seen, only partially shown, in two states with the hanging pocket storage 1, which is also only partially shown and has the net 49, wherein the rolling adapters 61 are introduced into the net 49 and interact with the hanging pocket storage 1. The net 49 is fixed to a fastening layer 821. The fastening layer 821 can be part of a structure 823, for example a ceiling, which accommodates the hanging pocket storage 1. However, it is also possible for the fastening layer 821 to form or have its own supporting structure, for example by means of beams or girders to which the net 49 is or can be fastened. Furthermore, it is conceivable for the fastening layer to have a rotating supporting structure and thus be part of the net 49, in particular of a statics of the net 49.The accompanying support structure can in turn be fixed, supported and / or firmly connected to the structure 823 by means of suitable fastening means.

[0316] Mounting devices 827 are fixed or can be fixed to the fastening layer 821, which in turn serve as bearings for the other components of the network 49. These can be fixed or mounted on the mounting devices 827. The other components of the network 49 are, in particular, an energy-conducting layer 807, which can be arranged in the vertical or Z direction below the fastening layer 821. The energy-conducting layer 807 serves to provide the drive energy 59 for the rolling adapters 61, in particular for driving and / or braking, preferably for carrying out autonomous or semi-autonomous driving maneuvers. The drive energy 59 can be provided in the form of mechanical energy, electrical energy, electromagnetic radiation, and / or magnetic field energy for inductive transmission. It is conceivable to design the energy-conducting layer 807 and the fastening layer 821 as an integral component.

[0317] Also arranged in the vertical or Z-direction below the energy-conducting layer 807, the net 49 has a traction layer 809. The traction layer 809 preferably has two parallel and spaced-apart traction surfaces 813 on which the wheels 57 of the rolling adapters 61 can roll, in particular while transmitting a drive or braking force.

[0318] The rolling adapters 61 have a height H and a length L, which are symbolized in Figure 4A, B by means of curved brackets.

[0319] The rolling adapters 61 each have an optional head 817, a number of wheels 57, and a shaft 819. The shaft 819 has a width B (in the Y direction, i.e., transverse to the direction of travel), which is symbolized in Figure 5B by a curved bracket, and connects a hanging pocket receptacle 815 to the wheels 57. When the rolling adapters 61 are inserted, the shaft 819 is arranged between the traction surfaces 813 of the traction layer 809. The traction surfaces 813 are arranged parallel to one another at a distance A. The distance A is symbolized in Figure 5B by a curved bracket.

[0320] In order for the shaft 819 to be arranged between the traction surfaces 813, the distance A is greater than the width B of the shaft 819 of the rolling adapter 61. The shaft 819 and the traction surfaces 813 preferably form a clearance fit, by means of which a transverse guidance of the rolling adapter 61 rolling on the net 49 can take place.

[0321] In the following, a method for carrying out maintenance work on a hanging bag warehouse 1, for example the previously described hanging bag warehouse 1 with hanging bags that can be moved on the network by means of the rolling adapters or that can be moved autonomously or at least semi-autonomously by means of the rolling adapters for receiving the stored goods, is described in more detail with reference to the drawing, in particular Figure 6, which shows a flow chart.

[0322] In a first step 839, the rolling adapter 61 to be removed is selected, which is indicated in Figure 4A by a first arrow 829.

[0323] The optional separation of the hanging pocket 5 from the rolling adapter 61 occurs in a second step 841. After selection, the hanging pocket 5 can be separated from the rolling adapter 61 and detached or removed therefrom, as symbolized by a second arrow 831 in Figure 4A. The separation is preferably non-destructive, repeatable, and reversible. This can preferably be done by manually grasping and releasing the hanging pocket 5 from a hanging pocket receptacle 815, for example, an eyelet or a hook 815, of the shaft 819. The hanging pockets 5 also have a corresponding hook or eyelet.

[0324] As a third step 843, the free path 803 is created, preferably by manually pushing away the further rolling adapters 61, as visible in Figure 4B and indicated by a third arrow 833.

[0325] Alternatively, the creation of the clear path 803 can also be achieved by autonomous or semi-autonomous driving maneuvers of the rolling adapters 61 in the direction of the third arrow 833. This can be achieved by means of a traveling drive controlled by a longitudinal dynamics control system. Particularly preferably, the additional rolling adapters 61 can remain in energy-transmitting contact with the energy-conducting layer 807 while the clear path 803 is being created, i.e., can be or remain continuously supplied with the drive energy 59. The energy transfer is indicated in Figure 5A by a double arrow 825.

[0326] The free path 803 is preferably at least as long as the height H of the rolling adapter 61. Preferably at least 1.2 to 2 times as long in order to be able to remove the rolling adapter 61 from the net 49 conveniently and without collision.

[0327] As a fourth step 845, the rolling adapter 61, more precisely its shaft 819 (and optionally its head 817), can be pivoted into the free path 803. The pivoting occurs about a pivot axis perpendicular to the direction of travel of the rolling adapter 61, preferably a wheel axis 811 of the rolling adapter 61 or a support point 611 of the wheels 57 on the net 49, more precisely the traction layer, preferably the traction surfaces 813, of the net 49. The pivoting movement of the selected rolling adapter 61 is indicated in Figure 4B by a curved arrow 835. It is approximately 90 degrees and can be performed either counterclockwise or clockwise from a resting state or from a state suspended in the net 49 and can be accomplished by manual gripping and turning or, preferably, by mechanization such as a robot.

[0328] For the actual removal, in a fifth step 847, the selected rolling adapter 61 is guided out of the net 49 through the free space 805 or the clear height EH between the energy-conducting layer 807 and the traction layer 809 of the net 49 at an angle or transversely to the direction of travel, as shown in Figures 4B, 5B by the fourth arrow 837. In particular, at least a minimal lifting of the rolling adapter can also take place.
