Description

field of the invention

The invention 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 partially autonomously by means of the rolling adapters for receiving stored goods, a rolling adapter according to the method, a hanging bag warehouse and a warehouse arrangement.

State of the art

In automated warehouses, production facilities and when transporting goods, such as in mail order, it is necessary to load goods into and unload them from containers as automatically as possible. The goods can be stored in these containers before they are delivered and then reach the station where they are packaged for further transport to the customer. Transport within the warehouse is usually carried out using overhead conveyors. The containers are usually bags that are made like fabric bags and are hung on a rail system with a kind of wire hanger at the top. A container of this kind is available, for example, from the WO 2014/012965 A1 known. Its side wall elements are controlled via a rod so that the side wall elements, which are connected to one another via a connecting area, can be opened up. In the area of a loading station, the containers are also transferred to a horizontal or inclined position.

Comparable containers for conveying goods and associated overhead conveyor systems are known, for example, from DE 10 2004 018 569 A1 , EP 2 130 968 A1 or EP 2 196 415 A The transport bags described there are made of flexible materials in the form of a loop in which the goods to be conveyed are held. For loading, these transport bags are opened from above in order to be able to place the goods to be conveyed into the loop. Unloading is carried out by either removing the goods from the side of the loop or ejecting them or, for example, according to the EP 2 130 968 A1 The loop is opened downwards. Furthermore, the DE 103 54 419 A1 A conveyor carrier is known which has a relatively rigid and flat plastic wall with a cutout for loading and unloading with conveyor material. Other conveyor containers are made like hanging flat plastic tubs which are covered on one side with elastic materials, which clamps the conveyor material.

It is known to load such containers mechanically and unload them manually. A transport cycle is based on the slowest process, which also depends on the amount of transported goods. In particular, a large number of individual goods can slow down loading and/or unloading. For example, unloading and/or assembling disassembled transport containers can determine the maximum possible transport cycle. The EP 2 686 258 B1 relates to a suspended conveyor system with a transport bag for automatically unloading a loaded piece of goods and with an unloading station. The transport bag has a horizontal base on which the piece of goods can be stored for transport purposes. The base interacts with a lifting device which is designed to raise the base of the transport bag loaded with at least one piece of goods in a vertical direction when the transport bag is in an unloading position in such a way that the at least one piece of goods can be pushed out centrally by means of a pushing device through a front side of a base body of the transport bag, wherein the pushing device has a slide which engages through another front side of the base body into an interior of the base body where the at least one piece of goods is located when the base is raised. For unloading, the two opposite open front sides, the base which can be raised in the vertical direction and the slide of the pushing device which reaches through one of the front sides are therefore required. From the DE 20 2017 100 206 U1 A conveying material container for a suspended conveyor system for transporting conveying material is known, which can be adjusted between an open position and a closed position. The conveying material 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 conveying material can be stored within the conveying material container, and an ejection position in which the conveying material can be ejected from the conveying material container.

From the DE 10 2018 105 795 A1 A method for loading or unloading a conveyed material held on a flexible material of a conveyed material container by means of a station such as an unloading station and/or a loading station of an overhead conveyor system, as well as a conveyed material container, unloading station and overhead conveyor system according to the method are known. The conveyed material container is brought closer to the station, where an attractive force is then created between the station and the conveyed material container to couple the flexible material of the conveyed material container. The conveyed material container coupled in this way is tilted and the conveyed material is ejected from the conveyed material container in a sliding movement.

The DE 10 2018 128 417 A1 describes a method for transporting and sorting a sorter bag suspended from a roller adapter rolling on a rail network of a sorting system for transporting a piece of goods, characterized by: providing the rail network of the sorting system, providing the roller adapter of the sorter bag rolling on the rail network, providing an electrical drive energy for the roller adapter, converting the electrical drive energy provided by means of the roller adapter itself into kinetic energy for transporting the sorter bag and devices according to the method. The roller adapters are used to hang and move the sorter bags. For this purpose, they each have a chassis with two coaxially rotating wheels, a suspension arranged between the wheels and carried by them, on which the sorter bag is suspended, an electrical drive for driving the wheels and a control device or partial control device for autonomously or at least partially autonomously controlling the roller adapter along a travel path selected from a plurality of travel paths.

The WO 2020 160 585 A2 shows a transport carrier and a transport carrier system for a hanging conveyor device, in which the transport carrier comprises a universally usable base body and a support body that can be exchanged via a connecting device, which in a first configuration is provided with a completely enclosed receiving opening for transporting transport bags and in a second configuration with a hanging hook for transporting goods hanging on coat hangers. The connecting device comprises a profile groove running perpendicular to the longitudinal axis and a profile extension running perpendicular to the longitudinal axis. The profile groove forms an undercut and is provided with an insertion opening at the end in the direction of its longitudinal extension. The profile extension comprises a profile web and a profile head formed on the profile web to expand the cross-section.

The DE 10 2005 006 455 A1 shows a transport system for hanging objects that has a transport rail in which holding elements are guided so that they can move by means of a pair of rollers. The holding elements are carried along by bolt-shaped drivers of the drive chain that project downwards. To ensure that the holding elements do not inadvertently come out of engagement with the drivers, means are provided between the transport rail and the holding elements that prevent projections projecting between the drivers from coming out of engagement with the drivers at a predetermined maximum inclination of the holding element relative to the transport rail.

Summary of the Invention

Based on this prior art, the present invention is based on the object of facilitating maintenance work on roller adapters and/or an exchange of roller adapters in a hanging bag warehouse with a large number of hanging bags that can be moved by means of roller adapters, preferably autonomously or at least partially autonomously movable hanging bags.

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 drag chain-free, actuator-free and/or carrier-free net by means of rolling adapters or that can be moved autonomously or at least partially 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 attached, 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. The pivoting takes place 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 in the free path of the net. The free path can be understood as a section of the network on which there is currently no other rolling adapter. 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 free of restrictions on both sides in a Y direction, i.e. transverse to the direction of travel of the rolling adapter, which means that the energy-conducting layer and the traction layer are arranged at a distance from one another. However, it is also conceivable that the free space in the direction of travel or X direction is vertically limited on one side, so that the rolling adapter can be removed at least on one side. A traction layer can be understood as a roadway on which the 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. Preferably, traction is achieved by gravity, by means of which the wheels are attached to traction surfaces of the traction layer. Alternatively or additionally, however, a spring force can also be used to press the wheels onto the traction layer. The energy-conducting layer is particularly preferably arranged vertically above the traction layer in a direction of gravity. The spring force can act between the energy-conducting layer and the traction layer. A rolling adapter can be inserted into the net in the reverse order, whereby if necessary, a position for insertion must first be selected and the free path must be created there, then the rolling adapter with the Z axis aligned horizontally 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 occupied again by further rolling adapters. Analogously, to create the free space, rolling adapters previously located there can be pushed away, preferably by means of a manually applied force, or driven away, preferably autonomously or at least partially autonomously.

Preferably, when creating the free path, the coupling for transferring energy between the rolling adapters to be moved and the energy-carrying layer can be maintained. Preferably during the pushing away and/or particularly preferably during an autonomous or at least partially autonomous journey of the rolling adapters to be moved. Decoupling can be omitted and the supply of energy for the rolling adapters to be moved can be guaranteed during the entire removal process. For example, energy-requiring storage, travel processes and/or maneuverability on the network can be carried out or maintained.

In a preferred embodiment, the selected rolling adapter is pivoted around a wheel axis using manual forces. The rolling adapters have a preferably traction-supported connection to the net of the hanging bag storage via the wheels, whereby an existing pivot axis can be used with the wheel axis. The wheels can be switched to a freewheel for this purpose. Alternatively, pivoting can also be done by rolling the wheels on the net with the wheels locked. The pivoting movement then takes place around a horizontally moving pivot axis through the contact surfaces of the wheels on the net.

Alternatively or additionally, the free path on the network is created by means of autonomous driving maneuvers of the other rolling adapters, whereby the rolling adapters (61) each have their own drive that moves along and a longitudinal dynamics control that controls it, or optionally by moving, for example pushing away in the X direction, the other rolling adapters away from the selected rolling adapter using manual forces. It is therefore possible to create the required free path either by 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 free 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. For this purpose, messages, in particular driving instructions, can be exchanged between the rolling adapter to be removed and the ones to be moved. By creating a free path, the work of an operator can be made easier and at the same time it can be shown which rolling adapter is to be removed and maintenance work on the rolling adapters can be made significantly easier. Alternatively or additionally, signals to an operator are also conceivable, for example an optical and/or acoustic display to identify the rolling adapter to be removed. If necessary, the displaced rolling adapters can be manually or autonomously returned to their original location on the network after removal. It was recognized that, in comparison to conventional couplings such as drag chains or drivers, rotational and translational degrees of freedom can be created for the rolling adapter and the other rolling adapters due to the own drive, which can be used advantageously here for removing and inserting the rolling adapter. In particular, it was recognized that these degrees of freedom and the own drive in combination with the free space make it particularly easy to maintain/remove/insert the rolling adapters. The free space is drag chain-free and driver-free. This is also only possible with the own drive.

The task is also solved by a rolling adapter, set up, designed and/or programmed to carry out a previously described method. This results in the advantages described above.

The task is also solved 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, whereby the net has a traction layer with two parallel and spaced traction surfaces and a net energy-conducting layer, wherein the rolling adapter can be removed from the net or inserted into it by means of a manual intervention 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 of the rolling adapter, in particular of a head and a shaft, seen in the direction of travel, 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, seen 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 object is also achieved 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 for this purpose, with a net on which the rolling adapters roll, 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-conducting 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, wherein a height of the free space between the traction layer and the energy-conducting layer of the net is greater than a maximum length of the rolling adapter seen in the direction of travel. This dimensioning means that the rolling adapter fits into the free space even when pivoted, and the shaft of the rolling adapter can be arranged between the traction surfaces when not pivoted during a travel movement and can be guided through between them for removal or insertion if necessary. The rolling adapter can be freely moved transversely to the direction of travel or in the Y direction for removal or insertion when pivoted. Maximum width or length can be understood to mean that the shaft of the rolling adapter does not exceed a distance remaining between the traction surfaces of the network at any point over its entire extent. The rolling adapter and the rest of the hanging pocket storage work together, whereby maintenance work on rolling adapters and/or replacement of rolling adapters can be carried out more simply and easily, in particular due to the dimensioning of the rolling adapter and the network of the hanging pocket storage. The hanging pocket storage is preferably set up, programmed, constructed and/or has a rolling adapter described above to carry out a method described above. In addition, the advantages described above arise.

In a preferred embodiment of the hanging pocket storage, 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 about be removed without collision. With larger factors, removal can be carried out particularly comfortably. The hanging pocket storage is designed in such a way that the path can be cleared by pushing the other rolling adapters away. In particular, mounting devices are arranged at a sufficiently large distance from one another, in particular at least as large as the clear path to be created.

Alternatively or additionally, it is also possible for the free space in the direction of travel of the rolling adapters to be limited on both sides by a mounting device, with the energy-conducting layer and the traction layer being held on the mounting device. The mounting devices can provide a distance between the energy-conducting layer and the traction layer. Preferably, these are held in the Z direction exclusively by means of the mounting devices, so no further mounting means are required. 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 and 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. In addition, the structure of the network is comparatively simple.

Finally, the task of a storage arrangement for storing, sorting and/or picking stored goods is to provide a large number of previously described rolling adapters, a large number of hanging pockets, in each of which at least one stored good can be accommodated and which are attached to the rolling adapters and can be detached from them without causing any damage, and a previously described hanging pocket. The problem is solved by a hanging bag warehouse in which the hanging bags on the roller adapters and the hanging bags attached to them can be stored, moved, sorted and/or picked, whereby individual roller adapters can be removed from the rest of the storage arrangement as required using a previously described procedure. The interaction of the hanging bag warehouse, the roller adapters that can be inserted and removed therein and the hanging bags that can be attached to them result in the advantages described above.

Further advantages emerge from the subclaims and the following description of a preferred embodiment.

Description of preferred embodiments

Before the invention is described in detail, it should be noted that it is not limited to the particular components of the device and the particular method steps, since these components and methods may vary. The terms used herein are intended only to describe particular embodiments and are not used in a limiting sense. In addition, when the singular or indefinite articles are used in the description or in the claims, this also refers to the plural of these elements, unless the overall context clearly indicates otherwise.

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

The hanging bag storage 1 has at least two levels 9, 13, here a total of four, whereby a first level 9 and a second level 13 are provided with reference symbols by way of example. More or fewer levels are conceivable, for example 10 levels or more, which are arranged vertically one above the other.

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 symbols.

The hanging bag storage 1 is used 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, which is 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.

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 to the ring conveyor system 23 and/or can be stored from there into the levels 9, 13 or the transfer buffers 7, 11 of the levels 9, 13.

In one 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 in a hanging pocket 5. Particularly preferably, autonomous driving, in particular by means of a traveling electric drive, control and/or movement of the entire hanging pocket 5 takes place before provision, during provision and/or transfer of the hanging pocket 5. The process preferably takes place by means of electric drives, in particular without drag chains and/or without carriers. For this purpose, the hanging pocket warehouse 1 is, for example, constructed at least partially or entirely without drag chains and/or without carriers, preferably at least within the levels 9, 13.

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

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

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

Alternatively, however, it is also conceivable that the hanging bags 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 bag warehouse 1 by means of the ring conveyor system 23, i.e. without the respective hanging bags 5 remaining in the unloading station or being available there, for example in order to continue driving or being transported further to the transfer point 53 after unloading.

Particularly preferably, the hanging pockets 5 are designed so that they travel autonomously along the network 49. Hanging pocket warehouses 1 with autonomously moving hanging pockets 5 are known and are used, for example, in DE10 2018 128 417 A1 described, so that a more detailed description is omitted here. Preferably, a control device 25 is provided for monitoring and controlling the hanging pocket storage 1, in particular for specifying the desired sequence 15 and controlling the ring conveyor system 23, which exchanges information with the functional units of the hanging pocket storage 1.

2 shows a schematic side view of such a hanging pocket 5 for the 1 shown hanging pocket bearings 1 and

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

For this purpose, they have wheels 57 and can preferably be driven by means of a drive energy, which is only indicated by the reference number 59, and a drive that uses this energy. A conveyor chain circulating in the anergy-conducting layer and/or mechanical conveyor means for transferring mechanical energy from and to the roller adapters 61 are also conceivable. The hanging pockets 5 can be designed in two parts and have a roller adapter 61 and a pocket material suspended or suspended thereon, in particular detachable without causing any damage, in particular sagging and/or foldable material in which a stored item 3 can be accommodated. In 3 A possible direction of movement of the hanging pockets 5 in the network 49 is indicated by means of a double arrow 51. The hanging pockets 5, in particular their rolling adapters 61, are set up, programmed and/or designed for autonomous or semi-autonomous driving on the network 49. For this purpose, these, in particular the rolling adapters 61, can have their own drive, preferably an electric drive, and their own longitudinal and transverse dynamics control.

By means of the longitudinal control, preferably at least two driving states from the following group can be set: stopping and driving forwards. Preferably from the group: reversing, stopping and driving forwards. Particularly preferably, different speeds and/or transient driving states can be set in each case, in particular in combination with a longitudinal acceleration regulation/control. In a special 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 forwards, reversing, holding, accelerated driving forwards, accelerated reversing, braked driving forwards, 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 adjusting elements. The term "free of adjusting elements" can be understood to mean that the network 49 does not have any active adjusting elements that influence the transverse dynamics of the rolling adapters 61 or hanging pockets 5, on which wheels or contact surfaces can be supported transversely to the direction of travel to bring about a change in direction that can be adjusted on the network side, as is known, for example, from classic adjustable switches.

Particularly preferably, the net 49 is constructed horizontally or essentially horizontally. Essentially horizontal can be understood here to mean 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 gravity-free, and therefore not gravity-induced. In addition, the drive can be designed as an electric drive, whereby the longitudinal dynamics control or the drive can be carried out without a drag chain, without gravity and/or without a driver.

In 2 the hanging pocket 5 is shown with the stored goods 3 held in it. The stored goods 3 are located within a U-shaped hanging material, in particular a flexible material. Loading and unloading can take place in particular from above or from the side.

Insofar as the terms X-direction, Y-direction and Z-direction are used in this application, this can be understood to mean a Cartesian coordinate system that travels with the hanging pockets 5 or rolling adapters 61, in particular their drive, wherein the X-direction can indicate a direction of travel, the Y-direction a direction transverse to the direction of travel and horizontal in the case of a flat travel movement 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.

4 shows a schematic side view of the net 49 filled with the rolling adapters 61 of the hanging pocket storage 1 outlined in the previous figures in two states A and B to illustrate a removal process of one of the rolling adapters 61 and 5 a schematic cross-section of the 4 shown network 49, also in states A and B. In the following, the 4 and 5 the process of removing the rolling adapter 61 is explained in more detail.

A bearing arrangement 801, only partially shown, can be seen in two states A and B with the hanging pocket bearing 1, also only partially shown, which has the net 49, wherein the roller adapters 61 are introduced into the net 49 and interact with the hanging pocket bearing 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, that accommodates the hanging pocket bearing 1. However, it is also possible for the fastening layer 821 to form or have its own support structure, for example by means of beams or supports to which the net 49 is or can be fastened. It is also conceivable for the fastening layer to have a running support structure and to this extent is part of the net 49, in particular a statics of the net 49. The running support structure can in turn be fixed to the structure 823, mounted and/or firmly connected to it by means of suitable fastening means.

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.

The net 49 also has a traction layer 809 arranged in the vertical or Z direction below the energy-conducting layer 807. The traction layer 809 has two traction surfaces 813 arranged parallel and spaced from one another, on which the wheels 57 of the rolling adapters 61 can roll, in particular while transmitting a driving or braking force.

The rolling adapters 61 have a height H and a length L, which in 4 A are symbolized by curved brackets.

The roller adapters 61 each have a head 817, the wheels 57 and a shaft 819. The shaft 819 has a width B which is 5 B symbolized by a curved bracket. The shaft 819 is in the inserted state of the rolling adapter 61 between the traction surfaces 813 the traction layer 809. The traction surfaces 813 are arranged parallel to each other at a distance A. The distance A is in 5 B symbolized by a curved bracket.

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.

In the following, with reference to the drawing, in particular the 6 , which shows a flow chart, 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 partially autonomously by means of the rolling adapters for receiving the stored goods, is described in more detail.

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

The hanging bag 5 is separated from the rolling adapter 61 in a second step 841. After selection, the hanging bag 5 can be separated from the rolling adapter 61 and hung or removed from it, as indicated by a second arrow 831 in 4 A symbolized. The separation is non-destructive, can be repeated as often as desired and is reversible. This can preferably be done by manually grasping and releasing the hanging bag from an eyelet or a hook 815 of the hanging bag 5. The hanging bags 5 also have a corresponding hook or eyelet.

As a third step 843, the free path 803 is created, preferably by manually pushing away the further rolling adapters 61, as in 4 B visible and indicated by a third arrow 833. Alternatively, the creation of the free path 803 can also be carried out by means of autonomous or semi-autonomous driving maneuvers of the rolling adapters 61 in the direction of the third arrow 833. Particularly preferably, the further rolling adapters 61 can remain in energy-transmitting contact with the energy-conducting layer 807 during the creation of the free path 803, i.e. can be or remain constantly supplied with the drive energy 59. The energy transfer is in 5 A marked by a double arrow 825.

The free path 803 is 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 comfortably and without collision.

As a fourth step 845, the rolling adapter 61, more precisely its shaft 819 and its head 817, can be pivoted into the free path 803. The pivoting takes place about an axis that is transverse 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 net 49, more precisely the traction surfaces 813 of the net 49. The pivoting movement of the selected rolling adapter 61 is in 4 B by means of a curved arrow 835. It is approximately 90 degrees and can be carried out 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 means of a mechanization such as a robot.

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 LH 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 the 4 , 5 B shown by the fourth arrow 837. In particular, at least a minimal lifting of the rolling adapter can also take place.
