Description

[0001] This application relates to and claims the priority of German patent application 102022002691.0 filed on July 22, 2022 and German patent application 102023000660.2 filed on February 24, 2023, the disclosures of which are hereby expressly incorporated as a whole into the technical solution of this application. Technical Field

[0002] The invention relates to a hanging bag warehouse equipped with follow-up hanging bags and a method for operating the hanging bag warehouse. Background Art

[0003] In automated warehouses, production facilities and during cargo transportation (e.g., mail order), it is necessary to load the transported goods into the transported goods container and unload them again from the transported goods container as automatically as possible. The goods can be stored in these transported goods containers before delivery and arrive at the station where they are packaged for further transportation to the client. The transportation in the warehouse is usually carried out by a suspended conveyor. The transported goods container is usually a bag made like a sack and is suspended in a track system at the top by a wire bow. This transported goods container is known, for example, from WO2014 / 012965A1. Its side wall elements are controlled in this way by a connecting rod so that the side wall elements connected to each other by the connecting area can be opened. In the loading station area, the container is also transferred to a horizontal or inclined position.

[0004] For example, comparable conveying goods containers and related suspended conveying devices are known from DE102004018569A1, EP2130968A1 or EP2196415A. The transport bags described there are made of flexible material in the form of a ring-shaped piece (Schlaufe), in which the conveying goods are held. For loading, these transport bags are opened from above so that the conveying goods can be placed in the ring-shaped piece. Unloading is achieved by taking out or ejecting the conveying goods from the side of the ring-shaped piece or, for example, opening the ring-shaped piece downward according to EP2130968A1. In addition, a conveying goods carrier is known from DE10354419A1, which has a relatively hard and flat plastic wall, which has a cutout for loading and unloading the conveying goods.

[0005] Other conveying goods containers are made as suspended flat plastic pallets, one side of which is covered with elastic material, which sandwiches the conveying goods.

[0006] It is known that such transport containers are loaded mechanically and unloaded manually again. The transport rhythm depends on the slowest process, which also depends on the transported transport quantity. In particular, a large number of individual transported goods may slow down the loading and / or unloading. For example, unloading and / or assembling the disassembled transport container can determine the maximum possible transport rhythm. EP2686258B1 relates to a suspended conveying system, which has a transport bag and an unloading station for automatically unloading loaded piece goods. The transport bag has a horizontal bottom, on which the piece goods can be stored for transport purposes. The bottom cooperates with a lifting device, which is arranged to lift the bottom of the transport bag loaded with at least one piece of goods in the vertical direction when the transport bag is in the unloading position, so that the at least one piece of goods can be pushed out in the center through the end face of the transport bag base body by means of a pushing device, which has a slide block, which extends into the interior of the base body through the other end face of the base body, and when the bottom is lifted, the at least one piece of goods is located there. Therefore, for unloading, two opposite open end faces, a bottom that can be lifted in the vertical direction, and a slide of a push device passing through one of the end faces are required. DE202017100206U1 discloses a conveying container of a suspended conveying device for transporting conveying goods, which can be moved between an open position and a closed position. The conveying container has a bottom that is mechanically assigned to an ejection device. By means of the ejection device, the bottom can be moved between a transport position and an ejection position, in which the conveying goods can be stored in the conveying container and in which the conveying goods can be ejected from the conveying container.

[0007] DE 10 2018 105 795 A1 discloses a method for loading or unloading a conveying load contained on a flexible material of a conveying load container by means of a station of a suspended conveying system, such as an unloading station and / or a loading station, as well as a conveying load container, an unloading station and a suspended conveying system according to the method. The conveying load container approaches the station, where an attractive force is then generated between the station and the conveying load container to couple the flexible material of the conveying load container. The conveying load container thus coupled tilts and the conveying load is ejected from the conveying load container in a sliding motion.

[0008] DE102018128417A1 describes a method for transporting and sorting sorting bags suspended on a rolling adapter for transporting piece goods, wherein the rolling adapter rolls on a track network of a sorting device, characterized in that a track network of a sorting device is provided, a rolling adapter for the sorting bag rolling on the track network is provided, driving power for the rolling adapter is provided, and the driving power provided is converted into motion energy for transporting the sorting bag by the rolling adapter itself, and a device according to the method. The rolling adapter is used to suspend and move the sorting bag. For this purpose, the rolling adapters each have a running gear with two coaxially rotating wheels, a suspension part arranged between the wheels and supported by the wheels (the sorting bag is suspended on the suspension part), an electric drive device for driving the wheels, and a control device or a sub-control device, which is used to autonomously or at least partially autonomously control the rolling adapter along a travel path selected from a plurality of travel paths.

[0009] Furthermore, it is known that industrial objects communicate with one another according to network standards, which is also referred to as the Industrial Internet of Things (IIoT). Summary of the invention

[0010] Starting from this prior art, the present invention is based on the task of being able to individually access a large number of autonomously or at least partially autonomously moving hanging bags in a hanging bag warehouse, in particular up to 1.5 million hanging bags, with the lowest possible transmission power density and the highest possible data rate, and in particular to coordinate the large number of autonomously moving hanging bags present in the hanging bag warehouse, preferably to control the goods flow of the stock goods contained in the hanging bags with the lowest possible effort.

[0011] The object is achieved in a hanging bag warehouse for storing, order picking, sorting and dispatching stock goods by: a network, on which a plurality of hanging bags or hanging bags suspended on rolling adapters can move autonomously or at least partially autonomously by means of respectively following longitudinal and lateral dynamic control devices; a control device, by means of which the hanging bag warehouse can be controlled and / or monitored and / or the storage, order picking and sorting of stock goods can be controlled and the sequence of stock goods for dispatching stock goods can be predetermined; a plurality of rolling adapters and hanging bags suspended or capable of being suspended on the rolling adapters, the rolling adapters or hanging bags A longitudinal and transverse dynamic control device is provided, respectively, and at least one stock can be contained in a hanging bag and can be removed from the warehouse again; a first communication device, by means of which a communication path A can be established between a control device and a receiver, such as any single hanging bag; and a second communication device, by means of which another communication path B independent of the communication path A can be established between the control device and the receiver; the hanging bag and / or the rolling adapter and / or the receiver can be freely addressed, accessed and / or controlled by the control device by means of and selectively by using one or both of the two communication paths A and B. Through two independent communication paths, more messages can be sent to the hanging bags as a whole and received from them. The communication paths can be used flexibly and according to the position of the corresponding hanging bag in the hanging bag warehouse. The transmission power density can be minimized and the data rate can be maximized. Thus, a particularly large number of suspension bags, preferably more than 10,000, in particular up to about 1,000,000, preferably up to 1,500,000, preferably with a density of up to 20, in particular between 10 and 20 suspension bags per meter, can be accessed and controlled. Once accessed or a command is received, the individual suspension bags can be moved autonomously or at least partially autonomously through the suspension bag warehouse without further messages. Once the command is completed, the accessed suspension bag can enter a low-wear and / or energy-saving waiting / stationary phase and send a new message with a new command at a later time or immediately afterwards and receive the message by the recipient.

[0012] Preferably, it is possible that communication paths A and B have: a hanging bag having a first transceiver device that follows and is configured for communication path A and a second transceiver device that follows and is configured for communication path B; a control device for centrally controlling a hanging bag warehouse, generating messages, and sending and receiving messages via communication paths A and B; a plurality of intermediate control devices that are preferably connected by fixed wires downstream of the control device, each of which is equipped with its own computing power and is configured for communication path A; a cluster of 2 to 10, preferably 2 to 6, preferably 4 beacons I, which are connected, preferably fixed wired, downstream of one of the intermediate control devices and the beacons I are respectively configured for communication path A; a cluster of 2 to 10, preferably 2 to 6, preferably 3 beacons II, which are connected downstream of one of the beacons I and the beacons II are respectively configured for communication path A, and / or a plurality of beacons III, which are connected, preferably fixed wired, downstream of the control device and are configured for communication path B.

[0013] The cluster of beacons I is preferably installed in a hanging bag warehouse, especially in the edge area. Thus, a relatively short path, especially a radio path, can be used to reach or address the hanging bag from the edge area to the inside of the entire hanging bag warehouse. For this reason, the corresponding beacon I can be selected so that the distance between the beacon I and the receiver is as short as possible. It is conceivable that the cluster of beacons I is set as a structural unit, especially installed in a common housing. Therefore, wiring costs can be saved. The further extension of the corresponding communication path from beacon I to beacon II can be carried out wirelessly through a path, especially a radio path, and the corresponding path can preferably be established in the same way all the time, so that the selection cost of each element of the communication path A can be reduced. Therefore, it is only necessary to determine which beacon II has the shortest distance with the receiver. Communication path A then extends there directly or through any number of other hanging bags as an intermediary. The communication path from the corresponding beacon II to the central control device extends to an assigned beacon I via a pre-selected or preferably established path and passes through the assigned intermediate control device and extends from there to the central control device through a fixed connection.

[0014] Alternatively, it is conceivable that, in order to reduce the transmission power density even further, very nearby suspended bags or receivers can be accessed directly via a path from beacon I as an exception to access via the respectively assigned beacon II.

[0015] Preferably, beacons II are connected downstream of the corresponding beacons I in the hanging bag warehouse, especially at transport nodes, especially in a certain interval pattern (especially almost uniformly distributed or uniformly distributed) in the hanging bag warehouse, preferably via a radio path. Beacons II can be arranged, for example, at the transition or intersection between the hanging bag storage area (i.e., the area where the hanging bags move little) and the dispatch line (in which the hanging bags are sorted) and / or the express line (in which the hanging bags travel relatively quickly between the storage area and the entrance / exit or sorting device and / or the endless conveyor device).

[0016] A plurality of beacons III can be permanently connected to the downstream of the control device. Beacons III can also be installed in the hanging bag warehouse, in particular at the edge area of ​​the hanging bag warehouse. Unlike beacons II, beacons III can be installed at the entrance / exit or sorting device and / or the ring conveyor and / or the transfer buffer. By means of beacons III, the communication required for the sorting process and / or the outbound process can be carried out centrally and locally and therefore particularly resource-saving, i.e. at a relatively low power density and a high data rate.

[0017] Another preferred possibility is that the communication path A from the central control device to the addressed hanging bag or recipient can be led to the recipient, in particular the addressed hanging bag, via one of the intermediate control devices, one of the beacons I, one of the beacons II or directly from one of the beacons I (by means of which a path to the recipient and / or beacon II can be established respectively), and / or a plurality of hanging bags, and the communication path B can be led from the control device via one of the beacons III to the recipient and / or another recipient in parallel therewith independently of the communication path A, the communication paths A and B having different communication protocols and / or paths. Data can be transmitted via both paths, for which the paths used can be kept particularly short in order to reduce the overall transmission power density and thus also the current consumption of the hanging bag warehouse.

[0018] The intermediate control device can be equipped with its own computing power and is preferably located below the central control device in the hierarchy. The intermediate control device itself can also take on tasks and relieve the load of the central control device.

[0019] The beacon III can also be connected downstream of the central control device and communicate with the recipient via the path as soon as the recipient is within the range of the beacon III. The path can be a bidirectional send / receive path, and data can also be transmitted from the recipient or the corresponding hanging bag to the central control device.

[0020] In a particularly preferred embodiment, the hanging bag warehouse is designed for and / or has at least 10,000, preferably at least 500,000, in particular at least 750,000, at least 1,000,000, at least 1,500,000, preferably between 500,000 and 1,500,000 hanging bags, which can be freely selectively addressed, accessed and / or controlled by the control device by means of and by using the two communication paths A and B. Thus, the entire hanging bag warehouse can be flexibly controlled.

[0021] In another embodiment, the beacon I, beacon II and hanging bag each have a first transceiver device set for communication path A, the first transceiver device is selectively set to receive, send or forward messages, and the number of transceivers used for transmitting a single message via communication path A is flexible. Therefore, communication path A can be adapted according to the position of the recipient in the hanging bag warehouse, and the division into multiple single paths can reduce the transmission power over the entire distance compared to a single path, especially a radio path. The power of each transceiver can be designed to be relatively low and thus save resources.

[0022] It is also conceivable that the intermediate control device is hardwired downstream of the control device, the cluster of beacons I is hardwired downstream of the respective intermediate control device, the cluster of beacons II is connected or connectable downstream of the respective beacon I via a preferably establishable path and the receiver can be addressed and / or accessed via one of the beacons II or from the beacon II via any number of other hanging bags. The communication between the control device and the receiver preferably takes place partly via a wired connection and partly via a path, in particular a radio path. The partially wired communication can additionally minimize the transmission power without giving up the advantage of being able to access the hanging bag individually and independently of the current stop by radio.

[0023] Finally, it can be provided that the beacon III and the second transceiver of the hanging bag have standard Bluetooth Low Energy (BLE) and the communication path B can be established according to this standard. This can be done directly between the corresponding beacon III and the recipient. A fast and preferably bidirectional communication limited to the area of ​​the hanging bag warehouse can be carried out, in particular for special tasks such as sorting or warehousing and outbound. Other tasks, such as controlling a simple transfer between two locations in the hanging bag warehouse, in particular a simple transfer via other paths, can be carried out via the communication path A, which can access each receiver at any position in the hanging bag warehouse through its high flexibility and range of action. Communication path A can preferably be used to wake up and shift one of the hanging bags after a longer period of inactivity (for example, for storing warehouse goods or storing empty hanging bags).

[0024] It is also conceivable that, in addition to the follow-up transceiver, an immovable beacon II is also provided in the hanging bag warehouse. Beacon II can preferably have a transceiver of the same structure as the follow-up transceiver or with the same or at least similar protocol. Through beacon II, communication between the corresponding beacon I and the corresponding beacon II can preferably be realized. This has the advantage that the communication path A of the first channel can be selectively established through a fixed radio path between beacon I and beacon II or directly from a beacon I to a follow-up transceiver. Therefore, it is not mandatory to establish the communication path A through a beacon II. If necessary, radio communication can also be carried out directly from a beacon I, a follow-up transceiver, and a hanging bag.

[0025] Artificial intelligence can be used to select the communication path A to be established. It is also conceivable to use existing systems and protocols for this purpose, which are known as the Industrial Internet of Things (IIoT), for example. The intermediate control device can also have such a protocol or be adapted thereto and be designed to access the beacon I accordingly.

[0026] All the hanging bags of the hanging bag warehouse can be accessed flexibly, preferably bidirectionally, via the communication path A. That is, in order to send a message from the central control device, such as a path instruction, to the hanging bag, or in order to send a message in the opposite direction, such as reporting congestion and / or failure.

[0027] It is particularly advantageous that the radio communication and / or transmission power in the hanging bag warehouse can be reduced by setting another channel or communication path B at a specific point (especially the edge area of ​​the hanging bag warehouse, preferably in the area of ​​the outbound device, such as a conveying device that conveys in the vertical direction, especially a ring conveying device). The communication needs generated there for outbound delivery can be achieved in particular by a second radio technology and / or a relatively short distance (for example, a few centimeters to about 10 meters). This technology is known, for example, as Bluetooth Low Energy (BLE for short). It extends from the beacon III to one of the hanging bags in both directions. Compared with the first communication method, it is preferably possible to exchange different messages with the hanging bag. But for simplicity, it is also conceivable that at least the messages sent to the hanging bag, such as the path instructions, are the same. This can further reduce the complexity of communication and the cost of controlling the hanging bag itself.

[0028] Once one of the suspension bags reaches the receiving area of ​​one of the beacons III, in particular one of the conveying devices, a handshake can be performed and the beacon III takes over the communication. The beacon III is preferably located at the same central control device subordinate and may have other own control devices / computing capabilities and corresponding other protocols if necessary.

[0029] Communication can preferably be carried out via communication path A in the area of ​​the entire hanging bag warehouse, and the communication path A can have a collaborative and highly flexible network or can be established by the network respectively. This highly flexible network can include fixed-position participants and moving participants, which is usually also known as a mesh network. Participants can be designed and / or set as transmitters, receivers and intermediaries for forwarding information respectively. Therefore, it is also possible to visit the surrounding radio network participants multiple times if necessary. But the mesh network itself can be divided into an intermediate control device that is not movable and under the central control device, a subordinate and fixedly installed beacon I and a beacon II that is also fixedly installed in the hierarchy. As a special feature, although beacon II is preferably equivalent to the protocol, it is fixed in position, so that beacon II can obtain a prominent position when flexibly constructing a connection path, i.e., a corresponding communication path A, which can reduce the radio load without increasing the complexity of the system. The network can be designed to be self-learning for this reason and automatically identify non-movable participants and is preferably used to establish a connection. Therefore, the hierarchy of communication path A can preferably be generated by a self-learning process or adaptively.

[0030] The communication density in the hanging bag warehouse can be adjusted automatically and dynamically. For example, the communication density and the communication volume are usually relatively low in pure storage areas because the inventory goods are stored there immobile for several hours to several days.

[0031] Additional load relief can be achieved via communication path B by using communication path B in areas with high communication costs, such as conveyor systems and sorting devices in hanging bag warehouses. For this purpose, communication path B can have different radio channels or radio frequencies and / or radio standards than communication path A.

[0032] In the area of ​​the conveying and / or sorting equipment, there is a relatively high communication demand and traffic in a relatively confined space, which can be well managed by the second bidirectional protocol (BLE) of the second communication path B, so that the load on the highly flexible mesh network of the first communication path A can be advantageously relieved. In addition, the overall radio power of the hanging bag warehouse can be reduced. In addition, time-critical processes can be better managed in this way.

[0033] In one embodiment of the hanging bag warehouse, it can be provided that the density of the hanging bags and / or rolling adapters on the network is a maximum of 20 hanging bags per meter, especially between 10 and 20 hanging bags per meter, when viewed in the X direction and / or the driving direction and when traveling in a queue or stored at rest, and / or the network has a plurality of parallel driving paths with this density, viewed in the Y direction and / or the Z direction, and the hanging bags and / or rolling adapters and / or receivers can be freely addressed, accessed and / or controlled by the control device by means of and by using the two communication paths A and B. Relatively large amounts of stock can be stored, sorted and moved in a confined space, and despite the high density of the hanging bags, the radio power density can be kept so low that reliable addressing can be maintained.

[0034] Furthermore, in an alternative, it is possible that communication path A can be established over one or the larger first distance, which extends in the area of ​​the entire hanging bag warehouse, and communication path B can be established over one or the smaller second distance, which extends in the area of ​​the hanging bag warehouse with high communication costs and / or in the hanging bag warehouse in conveying devices and sorting devices with high communication costs. Thus, the communication can be adapted to the communication tasks that occur during autonomous driving, storage, sorting and unloading. As a result, the radio power density can be kept low.

[0035] Furthermore, it is conceivable that the communication path A has a highly flexible and / or self-learning mesh network and / or that the hierarchy of the communication path A can be adapted and / or generated by a self-learning process. This additionally eliminates the programming and control effort for routing.

[0036] Finally, alternatively or additionally, communication paths A and B may have different time characteristics and / or communication path A may have a relatively slower time characteristic adapted to stationary storage and addressing than communication path B and / or communication path B may have a faster time characteristic adapted to sorting or sorting and control in conveyor systems and sorting devices with high communication costs in a hanging bag warehouse than communication path A. Communication tasks in a hanging bag warehouse can be flexibly adapted to areas with high communication requirements and at the same time high requirements on the time characteristic.

[0037] Furthermore, the object is achieved in a method for operating a suspended bag warehouse equipped with suspended bags that can be at least partially autonomous or self-driving by causing the suspended bags to be driven at least partially autonomously and transmitting messages to the suspended bags wirelessly (especially partially wirelessly and partially wired) via a communication path A and a communication path B independent of it to control the at least partially autonomous driving. Communication can be carried out in parallel, selectively and flexibly and / or task-specifically on two channels and at a relatively high data rate at a relatively low transmission power density. The method is preferably implemented with the aid of the aforementioned suspended bag warehouse. In this regard, the aforementioned advantages result.

[0038] In a preferred embodiment of the method, once the corresponding hanging bag is within the range of one of the beacons III, a handshake is performed and control of the corresponding hanging bag is taken over via the communication path B to perform the sorting process, outbound process and / or inbound process of the hanging bag warehouse. The communication path A can be carried out over the entire hanging bag warehouse, wherein the communication for the process can be carried out with the aid of the communication path B. For this purpose, the communication path B can be taken over when approaching, wherein the communication path B can be designed for relatively short distances, in particular according to known industrial standards such as BLE. As soon as the corresponding hanging bag approaches one of the beacons III, transmission can be performed.

[0039] Alternatively or additionally, the corresponding follow-up of the hanging bag and the second transceiver set for the communication path B can be used for driving dynamics regulation, distance regulation and / or collision avoidance. For this purpose, the hanging bags located in adjacent areas or on the common driving path in the hanging bag warehouse can also be connected to each other through the protocol of the communication path A and / or the communication path B, preferably from which the distance between each other is derived, especially in order to decide which measures need to be taken based on this, such as adjusting the driving speed between each other and / or stopping to avoid collision and / or queue driving. That is, the second task can be met over a short distance. It is conceivable that the communication paths A and B are designed for different distances. Depending on the required distance, one of the communication paths A or B can be used. This can further reduce the radio power density. Additional consumption can be saved and / or overload of one of the communication paths A or B can be avoided. It is also conceivable that the time characteristics of the communication paths A and B are different from each other, wherein the communication path B can have a time characteristic or better time characteristic that is more adapted to the task than the communication path A, for example, in order to complete the task, especially the longitudinal control.

[0040] Information, for example messages containing route instructions, can be sent from the central control device to the individual suspension bags via a first channel or communication path A. The suspension bags then travel a distance on the network at least partially autonomously to reach the target location contained in the route instructions. This can be achieved by the central control device via a plurality of subordinate intermediate control devices, by these intermediate control devices respectively via a plurality of beacons I, and by the beacons I via transceivers, which are interconnected in a meshed manner and serve as an intermediary to the specifically addressed suspension bag. The intermediate control devices can have their own computing power.

[0041] The communication between the central control device, the intermediate control device and the beacon I can be carried out by wire, and the further communication is carried out by means of a plurality of radio paths that can be established over short distances of a few meters, in particular a maximum of 100 meters, preferably a maximum of 20 meters, by means of a transceiver. As a result, the transmission power can be kept low and the communication path A of the first channel that is actually realized in this case can be maintained and / or constructed flexibly.

[0042] Preferably, the transceiver of the communication path A and / or B can be moved with the suspension bag, ie the suspension bag and / or the rolling adapter have the transceiver.

[0043] The same messages can be sent via communication paths A and B and preferably also via communication path B distance information to other suspension bags can be obtained.

[0044] In the present application, a "beacon" can be understood as a non-movable signal beacon (signalfeuer) facing the moving participant, in particular a transceiver that can establish communication, in particular bidirectional communication and / or a mesh network (preferably according to BLE and / or IIoT standards) with the moving suspension bag. This can also be understood as a stationary transceiver that forwards information and, if necessary, amplifies the information in the sense of a relay station or repeater, i.e., achieves a larger range with a relatively low total transmission power.

[0045] It is conceivable to selectively send information to multiple hanging bags at the same time or to only one of the hanging bags via the communication path A. For this purpose, the hanging bags that are to receive one of the information together can have a common identification, for which the common information can be sent. Analogous to the principle of radio broadcasting, individual information and thus radio communication can be saved.

[0046] Further advantages emerge from the dependent claims and the following description of preferred exemplary embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The present invention is now further described with reference to the accompanying drawings. However, the embodiments are only examples, which should not limit the inventive concept to a specific arrangement. Before describing the present invention in detail, it should be pointed out that the present invention is not limited to the corresponding components of the device and the corresponding method steps, because these components and methods can vary. The terms used herein are only used to describe specific embodiments and are not used restrictively. In addition, if a singular or indefinite article is used in the specification or claims, this also relates to the plural number of these elements, unless the entire context clearly indicates otherwise.

[0057] Figure 1 A three-dimensional schematic diagram of the upper front side of the hanging bag warehouse 1 is shown.

[0058] The suspended bag warehouse 1 has at least two levels 9, 13, here a total of four levels, wherein the first level 9 and the second level 13 are provided with reference numerals by way of example. More or fewer levels, for example 10 or more levels, which are arranged vertically one above the other are conceivable.

[0059] Each level 9 , 13 of the suspended bag warehouse 1 has a respective transfer buffer 7 , 11 , wherein likewise only the first transfer buffer 7 and the second transfer buffer 11 are provided with reference numerals.

[0060] The hanging bag warehouse 1 is used for receiving, storing, arranging and / or removing stock goods 3. It can be used selectively as a pure warehouse or an arranging device. The conveying buffers 7, 11 are preferably arranged vertically one above the other, which is indicated by the line 27. However, it is also conceivable that only at least two conveying buffers 7, 11 are arranged one above the other and / or that they are arranged obliquely to the vertical spatial direction along the line 27.

[0061] An endless conveyor 23, preferably a plurality of such endless conveyors, also extends along an imaginary line 27 along which the transfer buffers 7, 11 are arranged. The transfer buffers 7, 11 are arranged adjacent to the endless conveyor 23 so that the stock items 3 can be transferred from the transfer buffers to the endless conveyor and / or can be deposited from the endless conveyor into the level 9, 13 or into the transfer buffers 7, 11 of the level 9, 13.

[0062] In one embodiment, the inventory 3 is conveyed directly into the endless conveyor 23. The inventory 3 preferably located in the hanging bag 5 is conveyed into the endless conveyor 23. It is particularly preferred that the entire hanging bag 5 is autonomously driven, controlled and / or moved before providing the hanging bag 5, during providing and / or conveying the hanging bag 5. The method is carried out in particular without a traction chain. For this purpose, the hanging bag warehouse 1 is, for example, at least partially or completely constructed without a traction chain, preferably at least in the layers 9, 13.

[0063] For this purpose, the hanging bag warehouse 1 has a network 49, for example a track network with connecting sections and branches such as intersections and / or switches. Preferably, it is a grid with straight tracks and tracks connected to each other by intersections and / or switches. For example, it has a rectangular grid.

[0064] In order to store the inventory 3 in the hanging bag warehouse, the hanging bag warehouse has a transfer station 53, through which the individual inventory is transferred to the individual hanging bags 5. Preferably, each hanging bag 5 is only transferred one inventory 3. However, multiple inventory is also conceivable, as long as they have space in the corresponding hanging bag 5. In the transfer station, the inventory 3 can be selectively buffered and directly transferred to the hanging bag 5, for which the hanging bag goes to the transfer station 53 and then preferably continues to drive autonomously to the storage position of the hanging bag warehouse 1.

[0065] At the unloading station 55 of the hanging bag warehouse 1, the stock 3 is taken out of the endless conveyor 23 again and provided there preferably in a predetermined or predeterminable sequence 15. It is conceivable that for this purpose a row of hanging bags 5 is driven from the endless conveyor 23 into the unloading station 55 or is transferred from the endless conveyor 23 to the unloading station 55 in the desired sequence 15, unloaded there and then returned for the next loading. The unloading station 55 can be arranged inside or outside one of the levels 9, 13, preferably in the lowest level.

[0066] However, it is also conceivable that the hanging bags 5 are conveyed by means of the ring conveyor device 23 and unloaded in the desired order at the unloading station 55 and are immediately transported empty again to the hanging bag warehouse 1 by means of the ring conveyor device 23, i.e. the corresponding hanging bags 5 do not stay in the unloading station or are not available there, for example, to continue to drive to or be further transported to the transfer station 53 after unloading.

[0067] The hanging bags 5 are particularly preferably designed so that they travel autonomously in the network 49. A hanging bag warehouse 1 with autonomously traveling hanging bags 5 is known and described, for example, in DE 10 2018 128 417 A1, so it will not be described in detail here. Preferably, a control device 25 is provided for monitoring and controlling the hanging bag warehouse 1, in particular for predetermining the desired sequence 15 and controlling the endless conveyor device 23, which exchanges information with the functional units of the hanging bag warehouse 1.

[0068] Figure 2 Shown for Figure 1 A schematic side view of such a hanging bag 5 of a hanging bag warehouse 1 is shown in FIG. Figure 3 Show multiple Figure 2 3D view of the suspension bags 5 shown in the figure, which are suspended in a network 49, which is designed as a rail network, for example. For this purpose, the suspension bags have wheels 57 and can be driven by a drive energy, which is only schematically indicated by the reference numeral 59, and a drive device using this drive energy. The suspension bag 5 can be designed in two parts and have a rolling adapter 61 and a bag material, in particular a flexible and / or foldable material, which is suspended or can be suspended on the rolling adapter and in which the stock goods 3 can be accommodated. Figure 3 The possible directions of movement of the suspension bag 5 in the network 49 are shown by double arrows 51. The suspension bag 5, in particular its rolling adapter 61, is configured, programmed and / or designed for autonomous or partially autonomous travel on the network 49. For this purpose, the suspension bag, in particular the rolling adapter 61, can have its own drive and its own longitudinal and transverse dynamics control.

[0069] exist Figure 23. A hanging bag 5 with stock 3 contained therein is shown. The stock 3 is located in a U-shaped drooping material, in particular a flexible material. Loading and unloading can be carried out in particular from above or from the side.

[0070] In addition to a drive device and a corresponding control device (not shown in detail), the suspension bag 5 also has a first transceiver 205 and a second transceiver 207. The transceivers can be selectively implemented separately or as an integrated component, preferably with at least different radio frequencies and / or transmission protocols.

[0071] By means of the transceiver, the hanging bag 5 can receive or send messages to other hanging bags 5 and / or the control device 25 via two communication paths. Thus, messages can be wirelessly transmitted to or sent by the hanging bag. This can be selectively achieved by one of the transceivers 205 or 207, for example, depending on the position of the corresponding hanging bag 5 in the hanging bag warehouse 1 and / or the current task, such as storing, transporting, out of storage, in storage, caching and / or sorting the inventory 3.

[0072] exist Figures 4 to 7 Possible communication paths are further described in .

[0073] Figure 4 and 5 A detail of a level 9 of the suspended bag warehouse 1 shown in the previous figures is shown, which level has two communication paths A and B. The remaining levels of the suspended bag warehouse 1 can be constructed similarly, ie likewise have communication paths A and B.

[0074] The communication path A extends from the central control device 25 via the first communication device 201 via multiple intermediate control devices 209, multiple beacons I and multiple beacons II and / or each hanging bag 5 located in the hanging bag warehouse 1 to the receiver 215. In this embodiment, the receiver 215 is also the addressed hanging bag 5, and the message 217 is sent to it or sent by it. A stock 3 can be contained in the addressed hanging bag 5 or the receiver 215. Therefore, for example, instructions can be sent via the communication path A to indicate how the stock 3 should be handled, especially where the stock is expected to arrive or where it should be transported. Then, the hanging bag 5 can perform these tasks by itself.

[0075] Through the participation of the hanging bag 5 itself as an intermediary, a mesh network can be formed and each individual hanging bag 5 can be accessed freely and selectively. It is particularly preferred that only a single stock 3 is present in each hanging bag 5, so that the stock can be called up individually. This allows for a maximum of flexible and rapid operation and / or sorting. Preferably, the beacon II is fixedly arranged at the switch and the beacon I is fixedly arranged at the edge region 211 of the layer 9. This simplifies the path formation for the communication path A.

[0076] The communication path B extends from the central control device 25 via the beacon III via a relatively short (in particular a few meters, in particular less than 10 meters), preferably bidirectional radio path (for example according to the BLE standard) via the second communication device 203 to the receiver 215 .

[0077] Preferably, the ring conveyor device 23 of the hanging bag warehouse 1 has one of the beacons III in each layer 9, 13. It is thus possible to carry out unloading, sorting and / or caching, and to transfer the hanging bags 5 from the layer 9 to the ring conveyor device 23, that is, preferably to sort the hanging bags 5 and / or the inventory goods 3 contained therein at the same time. After the handshake, all the hanging bags 5 within the range of action of the corresponding beacon III can be accessed almost simultaneously via a path 213, preferably a radio path, using time multiplexing and thus coordinating them. The corresponding message from / to the corresponding recipient 215 can also contain instructions for transferring to a new position in the hanging bag warehouse 1. It is preferred that the message 217 with the same structure is transmitted via the communication paths A and B to coordinate the hanging bags 5, so that the control device of the hanging bag 5 only processes the different transmission protocols of the communication paths A and B, but can only be designed for one type of information.

[0078] It is conceivable to use the communication path B bilaterally between at least two suspension bags 5, ie without the involvement of the central control device 25. This can additionally reduce the transmission power density in the suspension bag warehouse 1, since this task does not need to be performed by the central control device 25.

[0079] Figure 6 A tree diagram of the hierarchical structure of the first and second communication devices 201 and 203 is shown in order to illustrate the communication paths A and B that are possible therefrom. Figure 7 Show Figure 6 A partial view of the tree diagram shown in , with communication path B.

[0080] exist Figure 6 and 7 In FIG. 2 , preferably fixed-wired paths 213 are represented by solid lines and arrows and radio-based paths 213 are represented by dashed lines and arrows.

[0081] The first communication device is divided into five levels.

[0082] The central control device 25 is located on the uppermost first level, and a plurality of intermediate control devices 209 are connected downstream of the central control device.

[0083] These intermediate control devices are preferably wired to each other in the second level. For example, there are between 2 and 100, preferably about 5, intermediate control devices in each layer of the hanging bag warehouse 1. Preferably, the intermediate control device 209 is equipped with its own computing unit or computing power. This can be implemented as a standard component. Therefore, the tasks for path formation, path reconstruction (if the communication path A that has been formed is interrupted) and / or communication control can be outsourced to the intermediate control device 209 to reduce the load of the central control device 25.

[0084] A plurality of beacons I are provided in the third level below the second level. Preferably, four beacons I are connected downstream of each intermediate control device 209. The four combined beacons I can be installed in a common housing. Figure 6 In the figure, the four beacons 1 are indicated by a dotted quadrilateral. In addition, it is conceivable that the corresponding intermediate control device 209 is also installed in the housing. Therefore, each intermediate control device 209 can access four beacons 1.

[0085] Through the third level, each beacon I can access multiple subordinate beacons II, which are arranged in the fourth level for this purpose. The communication from the first level to the third level is preferably carried out by wire, and the components of the first, second and third levels are preferably fixedly installed on the hanging bag warehouse 1, preferably on the edge area 211.

[0086] As a further feature, the beacon II of the fourth level is preferably also installed in a fixed position in or on the hanging bag warehouse 1, preferably in or at an intersection, preferably at the transition between the storage area and the line (especially the dispatching line for shifting and / or the express line for rapid transport of the hanging bags 5).

[0087] Although the preferred beacon II is in principle configured to establish the corresponding communication path A like each hanging bag 5 and beacon I, beacon II is hierarchically connected downstream of a specific beacon I or is only accessed by this beacon I. This is achieved through the corresponding radio-based path 213. The advantage of the fixed-position allocation is that the path formation of the communication path A to one of the beacons II is always predetermined according to the hierarchy of the first to fourth levels or can be dynamically and / or self-learningly predetermined by an algorithm. The preferred beacon and the hanging bag 5 are equipped with the same hardware unit, and the corresponding functions, especially the routing of the message 217, can be realized dynamically, especially self-learningly and / or self-optimizingly, by corresponding devices and / or programming. Therefore, in principle, it is conceivable that the message is transmitted on any path on each of the five levels, but reasonable paths will appear during use, which can be used preferentially and especially extended by the fixed-position beacons I and II. These paths can also depend on the position of the receiver 215, but the paths of each position are respectively the same during the learning process, which saves resources in terms of routing and can realize optimized paths for the corresponding messages 217.

[0088] Only in the fifth level is the path formation or routing for transmitting the message 217 completely free, in particular each routing process depends on the respective position of the recipient 215 in the hanging bag warehouse 1 and can be transmitted to the recipient 215 via any number of other hanging bags 5, which is Figure 6 2 shows, by way of example, a message 217 which is transmitted via two further suspension bags 5 .

[0089] By dividing the first communication device 201 into a fixed-wired part (first to third levels), a part having a predetermined communication part path at least after a learning process (first to fourth levels) and a part that is free with respect to path formation (fifth level), a particularly large number of suspension bags 5 can be addressed independently of the location with a particularly low transmission power density at any position in the suspension bag warehouse 5. The transmission power density is relatively low here because many short paths 213 are used to transmit the corresponding messages 217 and / or some are fixed-wired and some are flexibly established.

[0090] According to a possible alternative, it is conceivable that a message is sent directly from the third level (i.e., one of the beacons 1) to the receiver 215 as needed, that is, bypassing the fourth level and sending the message directly to the fifth level, such as Figure 6 This may be limited to exceptional cases where the receiver 215 is particularly close to one of the beacons 1.

[0091] The second communication device 203 is divided into three levels, the first level of which also has a central control device 25 , that is, it is consistent with the communication path A or the first level of the first communication device 201 .

[0092] Downstream or below it, the second level of the second communication device 203 has at least one, preferably multiple beacons III, in particular each ring conveyor device 23 has one, for example 2 to 100 beacons III on each layer 9, 13, preferably each ring conveyor device 23 has about 10.

[0093] A hanging bag 5 or a receiver 215 is arranged in the third level of the second communication device 203 , and the third level of the second communication device 203 is consistent with the fifth level of the first communication device 201 .

[0094] The beacon III of the second level of the second communication device 203 is fixedly connected to the downstream of the control device 25. Once the hanging bag 5 or the receiver 215 enters the range of the corresponding beacon III, they are directly accessed by the second level, which is Figure 6 and 7 The partial circle line shown by the dotted line is represented.

[0095] exist Figure 7 In the figure, 6 suspension bags 5 are located within the range of action of beacon III, which is indicated in bold. Here, beacon III can access all six suspension bags 5 almost simultaneously and / or in a time-multiplexed manner and exchange messages 217 with them.

[0096] Figure 8 A flow chart of a method for operating a suspended bag warehouse equipped with suspended bags that can be driven at least partially autonomously or autonomously is shown.

[0097] In a first step 219, the suspension bag 5 moves or travels at least partially autonomously or autonomously on the network 49. The message 217 can contain the following targets for controlling the at least partially autonomous travel, which can be preferably wirelessly transmitted to the receiver 215 in a second step 221, and the receiver 215 can then go to these targets partially autonomously or autonomously. The message 217 can be transmitted optionally, especially depending on the task and / or the position in the suspension bag warehouse 1, via the communication path A or a communication path B independent of it.

[0098] Optionally, it is conceivable that once the corresponding hanging bag 5 is within the range of one of the beacons III, a handshake is performed and control of the corresponding hanging bag 5 is taken over via the communication path B, in particular in order to execute the sorting process, outbound process and / or inbound process of the hanging bag warehouse 1 via the communication path B.

[0099] Furthermore, it is conceivable to use the second transceiver device 207 of the suspension bag 5 provided for the communication path B additionally for vehicle dynamics control, distance control and / or mutual collision avoidance.

[0100] It goes without saying that the present description may be subjected to various modifications, changes and adjustments within the equivalent scope of the appended claims.
