The invention relates to a storage system having at least one shelf unit, wherein the shelf unit has plural shelves arranged on top of each other, wherein each shelf is logically subdivided in plural compartments arranged side by side. The invention relates further to a method for setting up such a storage system.
Technological Background
In order to satisfy the requirements of a modern and thus demanding logistics, it is necessary nowadays to make the storage systems used for this purpose intelligent, and to integrate them in superordinate total systems.
Generally, some approaches for automated storage systems having automatic detection devices are already known.
DE 10 2007 017 207 A1 describes a sensor for a detection of an occupancy, and discloses a drawer having a standard part of foamed material and recesses for receiving tools. A sensor formed as a reflected-light barrier is located at the bottom of a recess and comprises a light transmitter as well as a receiver arranged in the immediate vicinity. As a function of whether a tool is located in the recess or not, the emitted light is reflected or not, such that the receiver generates a signal only, if a tool is present in the recess.
DE 197 14 799 C2 shows a device for storing units of goods having a matrix of sensors arranged at the bottom of a goods shelf and corresponding signal lines, wherein in the area of the goods shelf the signal lines are formed by a conductor board stripe, on which also the sensors are mounted, wherein the sensors are pressure sensors, capacitive/inductive sensors or mechanical switches.
EP 1 217 345 A1 shows a system for controlling the flow of goods of different articles from plural suppliers to one usage site, wherein a storage is conceived at the usage site, which storage automatically detects the necessity to re-fill the shelf.
DE 698 27 454 T2 shows a method for managing a storage system having containers, wherein refilling of the containers is prompted automatically.
DE 20 2014 004 232 U1 shows a shelf unit for goods for the self-service withdrawal of bakery products. The shelf unit for goods has a stock compartment and at least one light barrier. This allows to detect the filling state of the stock compartment in the area of the light barrier.
EP 2 178 035 A1 discloses a method and an arrangement for an empty space measurement of storage spaces or transport spaces. A storage space or transport space is subdivided in plural partial areas. A distance measurement is performed in the partial areas. The results of the measurement are transmitted to a central entity. The central entity can process the results of the measurement, such that information on the occupancy of the storage space or transport space can be determined.
WO 2005/088494 A1 relates to a storage system having at least one receptacle for storing goods. The storage system has a gravimetric sensor element for detecting the goods. The storage system may have additional sensor types for detecting the goods.
DE 10 2004 035 819 A1 discloses a method for automatic detection of storage goods in a store-room. Herein, each single article that is stored in the store-room is provided with a transponder. Object-related data are transmitted from the transponder to a reading device and are registered by a storage management computer.
In addition to this, further solutions are known, which detect the weight by force sensors, such as e.g. weighing cells or resistance strain gauges, and thus detect an occupancy. Optical systems are known, in which cameras record images, and the image data are evaluated in respect of an occupancy detection.
There may be a need to provide an improved storage system as well as methods for setting up and for operating such a storage system, which enable an improved setting up of the storage system.
The invention provides a storage system according to the appended independent claim 1, a method according to the appended independent claim 17 for setting up such a storage system, and a method according to the appended independent claim 19 for operating such a storage system. Preferred embodiments of the invention are indicated in the dependent patent claims.
Exemplary embodiments of the invention are particularly advantageous, because an automatic measurement of the stocks (or inventories) in the individual compartments of the storage system can be effected. If the occupancy information shows a too low stock in a compartment, the communication device or the server can prompt a repeat order (or re-order) of the respective articles. These can subsequently be sorted into the respective compartments, wherein a measurement of the new stocks can be effected by the sensor assemblies. Thus, a simplified stock-keeping is possible. In addition, the occupancy information can for example be requested via the communication device or the server, such that also a remote request can be effected whether sufficient stocks of individual articles are present in the compartments.
According to an exemplary embodiment of the invention, there is provided a storage system having at least one shelf unit, wherein the shelf unit has plural shelves arranged on top of each other. Each shelf is logically subdivided in plural compartments arranged side by side, wherein a unique address is assigned to each of the compartments. Furthermore, the storage system has a sensor system for detecting an occupancy of the compartments, wherein the sensor system is configured to spatially scan the occupancy of one of the compartments so as to generate an occupancy information, which indicates a degree of occupancy of the respective compartments, as well as a data bus, which is connected to the sensor system and a communication device. The storage system is configured to perform the following steps:
The shelf unit may concern a shelf unit having inclined shelves, and the shelves may have a slope in the direction towards a withdrawal side of the shelf unit having inclined shelves. In a shelf unit having inclined shelves, the shelves have a slope in a filling and/or withdrawal direction, such that the articles stored in the compartments slide down in the withdrawal direction automatically after the withdrawal of an article. Thus, the articles lie without gap against each other. The use of a sensor system in such shelf units having inclined shelves is particularly advantageous, because a detection (or measurement) of the stock (or inventory) is possible with few sensors, because no possibly present free spaces between the articles need to be detected. It is only necessary to detect the position of the last article. If the length of the individual articles and/or the number of articles per unit length is known, the number of articles in the respective compartment can be determined in this way. For example, the length of the individual articles can be known already, or this is determined during the setting up of the shelf system and is stored. If the position of the last article is known upon a filling with the minimum quantity, it is for example also sufficient to inquire only the sensor element assigned to this position so as to check whether a minimum quantity of the respective article is present. For example, during the setting up of the shelf system, the shelf system can be filled with the minimum quantity, and the position of the last sensor, which indicates an occupancy, and/or the position of the first sensor element, which indicates no occupancy, can be detected.
The sensor system has for example plural sensor assemblies, and each one of the sensor assemblies is assigned to one of the compartments, wherein a sensor assembly to its part has a number of sensor elements arranged in a longitudinal direction of the sensor assembly. The assignment of the sensor assemblies to the compartments can simplify the control and/or the setting up of the storage system. The sensor elements arranged in the longitudinal direction can be arranged in the longitudinal direction of a compartment, for example in a shelf unit having inclined shelves in the withdrawal direction, such that a simple detection of the stock in a compartment can be effected.
In particular, each sensor assembly can be assigned precisely to one compartment, and the longitudinal direction of the sensor assembly runs in the direction of the slope of the compartments.
A sensor assembly can have a stripe-shaped, flexible or rigid conductor plate as a carrier. The conductor plate can be adapted to the shape and/or the geometry of the respective compartment.
A sensor assembly can be fixed to a lower side of a shelf, by which the compartment assigned to the respective sensor assembly is formed. Thereby, a space-saving arrangement of the sensor assembly is possible.
The storage system may further have a control electronics for each of the sensor assemblies, wherein the control electronics is configured to connect the sensor assembly t the data bus as well as to output the address assigned to the compartment and the occupancy information onto the data bus.
For example, at least one optical signalling means is uniquely assigned to each of the compartments, wherein the optical signalling means is connected to the data bus so as to receive via the data bus a signal for an optical indexing of the compartment and to realize the optical indexing. For example, a compartment, which is to be filled up, can be indexed by the signalling means.
The storage system can be configured to store a stock-taking point in time and to perform an automatic stock-taking upon reaching the stock-taking point in time. The determining (or measuring) of the stock (or inventory) of all compartments can require a specific time as a function of the size of the storage system, wherein it may be desired that no articles are withdrawn or sorted in during the determining of the stock. The point in time for the stock-taking can be selected such that no withdrawal or sorting in into the storage system occurs during the stock-taking, for example at night time.
For example, an occupancy plan is stored in the communication device, in which occupancy plan an assignment of goods types respectively to one or plural addresses and/or compartments and a threshold value for the occupancy quantity of goods of a respective goods type are stored. The communication device can be configured such that the quantity of goods of each goods type placed into stock in the storage system can be determined from the occupancy information received via the data bus and the respective assigned addresses, that the determined quantity of goods of each goods type is compared with the quantity threshold value assigned to this goods type, and that a signal can be sent, if the determined quantity of goods of this goods type falls below the quantity threshold value assigned to it. In this way, it can be ensured that a sufficient quantity of the articles stored in the compartments is always present.
According to embodiments of the invention, a remote maintenance program module can be installed on the communication device, which is addressable via the network and which can perform maintenance operations directly on the storage system. The remote maintenance program module is configured for example such that upon (or in response to) the receipt of a command via the network the sensor system is activated such that the occupancy information of a compartment specified by the indication of a corresponding address in the command is detected (or measured), and based on the occupancy information an occupancy information signal is generated, which is sent via the network.
The communication device can dynamically store occupancy information of the storage system, such that in the case of a system failure, the occupancy information can be restored at any time and can be used again upon a new system availability.
For example, the communication device is configured to connect to a computer via a local connection so as to visualize an occupancy plan stored in the communication device on a user interface of the computer.
The communication device can have a setup mode, wherein an occupancy of the storage system, which is detected (or measured) by the sensor system in the setup mode, can be stored as an occupancy plan, wherein the occupancy plan comprises in particular the goods type assigned to each one of the compartments and an occupancy threshold value assigned to this goods type, which threshold value is given by the occupancy detected by the sensor system.
The storage system may further have a hand-held scanner for optically determining (or measuring) an optically readable code, wherein each one of the compartments carries an optically readable code indicating the respective address, wherein the communication device is configured such that the assignment of a goods type to one or plural of the compartments is effected in that the communication device receives from the hand-held scanner an optically measured address and a goods type assigned to the optically measured address.
For example, the hand-held scanner is configured wirelessly and has a wireless communication interface for the communication with the communication device.
The sensor system may have one sensor assembly per compartment as a flexible, stripe-shaped conductor board.
The sensor assemblies can be fixed respectively to the lower side of a shelf, such that the signal transducers of one of the sensor assemblies can emit a signal in the direction towards the upper side of the shelf located respectively one level lower, and the signal receivers of one of the sensor assemblies can receive a signal from the shelf located respectively one level above through openings located in the shelf. Thus, only respectively one sensor assembly has to be installed in order to install a group of signal transducers as well as a group of signal receivers. Thereby, the installation effort is reduced and the constructional height of the sensor assembly is reduced. The signal direction from the signal transducer to the signal receiver thus runs from the top downwardly. However, the signal direction can run from the bottom upwardly, by arranging the signal receivers at the upper side of the compartment and the signal transducers at the lower side of a compartment.
The signal transducers and the signal receivers of a sensor assembly can be arranged pairwisely on the conductor board, such that a signal transmitted by one of the signal transducers can be received from a signal receiver of the same pair. Thereby, the signal transmitted from the signal transducer can be received simpler by the signal receiver, if the distance between the signal receiver and the signal transducer is shorter and/or the signal does not have to traverse the receiving space of the compartment. In particular, the signal can be configured weaker, such that the danger of an influencing by the signals of neighbouring signal transducers is lower. A further advantage consists in that no mutual alignment of the signal receiver and the signal transducer in the compartment has to be effected. The alignment is effected already by the arrangement on the conductor board. This has the advantage that a greater manufacturing tolerance is possible in the manufacturing of the shelf unit, because no alignment to each other of the shelves and/or of the sensor assemblies at the shelves is required.
For example, the signal transducers and the signal receivers of a sensor assembly can be arranged pairwisely on the same conductor board, in particular directly adjacently (or neighbouring), wherein the pairwisely arranged signal transducers and signal receivers are assigned respectively to one opening located in the shelf, such that a signal emitted by one of the signal transducers can be sent through the opening and be received [through the opening] by a signal receiver of the same pair.
In particular, the signal receiver and the signal transducer can be arranged adjacently (or neighbouringly) on the conductor board. For example, the signal receiver is arranged annularly around the signal transducer, such that it can receive the signal emitted by the signal transducer independently from the emitting direction.
The signal transducer, the signal receiver and/or conductor paths for interconnecting the signal transducers and the signal receivers are printed for example together with the data bus on the conductor board.
The shelves can have plural openings in the filling direction of the compartments, in particular in the direction of the slope so as to enable a signal receipt and/or a signal transmission by the sensor system, wherein the sensor assemblies of the sensor system are arranged underneath the shelves, and are covered with a film, which covers the openings, and which is applied in the filling direction on an upper side of the shelf. The film protects the sensor assembly from contamination, and in addition provides a plane area on the shelf. A sliding area can be formed by the plane film for example in shelf units having inclined shelves, which sliding area enables a better sliding-down of the articles within a compartment.
The film may concern a plastic film, in particular a PVC film, wherein the plastic film is transparent in particular in the range of a frequency of the signal receipt and/or the signal emission.
According to another exemplary embodiment of the invention, there is further provided a method for setting up a storage system, the method having the following steps:
The assignment of a goods type to one of the compartments can be effected by a hand-held scanner.
The hand-held scanner has for example a wireless communication interface to the communication device so as to transmit an assignment signal for assigning the goods type to one of the compartments to the communication device.
According to still another exemplary embodiment of the invention there is further provided a method for operating a storage system, the method having the following steps:
The optical signalling means can be connected to the data bus via the sensor assembly, and the electronic control of the sensor assembly, which may receive the false occupancy signal via the data bus from the communication device, can activate the optical signalling means of the respective sensor assembly for outputting the false occupancy signal.

At this time, the cross-section of a sensor assembly can assume plural possible shapes (
In an embodiment according to the invention, the sensor assembly may be formed as a flat stripe (or strip) (
In a further embodiment according to the invention, a test signal transducing device (or test signal transducer) 26 may be arranged beside (or is associated to) a signal receiving device 22, i.e. in immediate or at least collateral distance to the signal receiving device 22 (
In
The sensor elements may be integrated in the carrier 10 at least partially on a respective outer surface both as a signal transducing device 21 and as a signal receiving device 22, so as to possibly protect an according to sensor element on the one hand, or to possibly also obtain a smooth outer surface on the other hand. In
The signal transducer 21 could alternatively also be arranged on the upper side of the shelf (reference numeral 21′), in particular directly adjacently to the signal receiver 22. The signal emitted by the signal transducer can thereby be received simpler by the signal receiver, if the distance between the signal transducer and the signal receiver is shorter and/or if the signal does not have to traverse the receiving space of the compartment. In particular, the signal can be embodied weaker, such that the danger of an influencing by the signals of neighbouring signal transducers is lower. A further advantage may consist in that no mutual alignment between the signal receiver and the signal transducer needs to be effected in the compartment. The alignment may be effected already by the arrangement on the conductor board. This may have the advantage that during the manufacturing of the shelf unit, a greater manufacturing tolerance may be possible, because no alignment relative to each other of the shelves and/or of the sensor assemblies at the shelves may be required.
At this time, the sensor elements may be positioned and selected in terms of their type with respect to each other such that in the sensor assemblies 100a, 100b, at their outer surfaces 14a and 12b facing each other, always one signal transducer 21 and one signal receiver 22, respectively, may be opposing each other. Further sensor elements may be arranged on the outer surfaces of the two sensor assemblies 100a, 100b, which may face away from each other, wherein the further sensor elements may be respectively complementary to the very sensor element, which may be located on the respective sensor assembly on the outer surface facing the other sensor assembly. In this context, the term “complementary” refers to the respective other type of a sensor element. In
However, if a storage good G is contained in the surveillance space R, the signal path S may be disturbed and a signal S sent by a signal transducer 21 cannot be received by the signal receiver 22, which may be interpreted as a second occupancy state BZ2, namely that a storage good may be present in the surveillance space R (
In an embodiment according to the invention for the arrangement of a sensor assembly 100 according to the
The sensor element 20 may protrude from the surface of the sensor assembly 100 and thus may fill such a signal opening 315 at least partially. At this time, the sensor assembly may be positioned and at least in an attempt fixed in relationship to the delimitation element, such that the at least one sensor element 20 may come securely in coverage with the signal opening 315. In a further embodiment, the signal opening 315 may be filled at least partially with a material 316, which may be transparent for the type of signal used by the sensor elements, e.g. with a transparent synthetic resin. Thus, a smooth surface may be present and no dirt, which would disturb the signals, can accumulate in the signal openings (
Alternatively or in addition, a further protective layer 316 may also be applied, e.g. a foil (or film) or an adhesive tape of a transparent material (
In one embodiment of the invention, for the arrangement of a sensor assembly 100, a device (
Each sensor assembly 100 may have a plurality of sensor elements 20, which may be arranged, respectively, in a row (or line) at the respective sensor assembly 100. Because plural sensor assemblies 100 may be arranged on the delimitation element 310, respectively, parallel to each other, there may result a sensor matrix (
In an embodiment according to the invention, the delimitation elements 310, which may border or enclose a surveillance space, may have devices 325 (
If the length of the individual articles and/or the number of articles per unit length is known, for example also the number of the articles in the respective subarea TB can be determined. For example, the length of the individual articles can be known already, or this may be determined during the setting up of the shelf unit 400 and may be stored. For example, the position of the last sensor element having the occupancy state “present” and/or the position of the first sensor element having the occupancy state “empty” can be detected. Subsequently, the number of the articles can be input manually. With this information, as a function of the distance of the individual sensor elements, a calculation of the size of the individual articles and thus a precise determination of the number of the articles in the subarea upon withdrawal of individual articles may be possible.
Alternatively, the position of the last sensor element having the occupancy state “present” and/or the position of the first sensor element having the occupancy state “empty” can be stored. In order to check whether a minimum amount of the respective article is present, it can be sufficient to inquire only the sensor element assigned to this position. The time effort for an inquiry can thus be reduced significantly. For example, the shelf unit system can be filled with the minimum amount during the setting up of the shelf unit system, and the position of the last sensor, which may indicate an occupancy, and/or the position of the first sensor element, which may indicate no occupancy, can be detected.
The storage system 600 may further have a sensor system 200, which may consist of sensor assemblies 100, wherein one sensor assembly 100 may be assigned to each compartment TB. The sensor assemblies 100 may each be configured to scan the occupancy of the compartments TB, and to generate an occupancy information. A unique address, which may be figured (presented) on a barcode 680 on the front side of the compartment, may be assigned to each of the compartments TB.
Furthermore, a data bus 620 may be provided, which may be connected to a communication device 630, which can establish a network connection 640 with a server 650. The communication device 630 can send the occupancy information received via the data bus as well as the address of the compartments TB associated with the occupancy information via the network connection 640 to the server 650. Furthermore, the communication device 630 can receive control information of the server 650 via the network connection 640. For example, the control information may be instructions for performing a stock-taking or information for performing a remote maintenance.
The storage system may further have a hand-held scanner 670 for optically detecting (or measuring) an optically readable code, wherein each of the compartments TB may carry an optically readable code indicating the respective address. The communication device may be configured such that the assignment of a goods type to one or more of the compartments TB may be effected in that the communication device 630 may receive from the hand-held scanner 670 an optically measured address and a goods type assigned to the optically measured address.
The hand-held scanner can be configured wirelessly and can have a wireless communication interface for communicating with the communication device.
The compartments may further have signalling means 690, which, for example after receipt of a false occupancy signal, may output an optical signal that may indicate optically a false occupancy for a user.
For setting up the storage system 600, the communication device 630 may firstly be switched in a setup mode. Subsequently, there may be effected an occupation of the compartments TB of the storage system 600 according to a predetermined occupancy plan 700 with minimum stock amounts, below which repeat orders shall be prompted, as well as a detection of the minimum stock quantities by the sensor system 200, and a storage of the minimum stock quantities in the communication device. Finally, there may be effected a completion of the occupancy to the nominal stock in the storage system 100.
The operation of the storage system 600 after the setup may be effected by the following steps:
The process of the setting up as well as of the operation of the storage system 600 is indicated schematically once more in the
The storage system 100 can perform the occupancy detection permanently or periodically, for example in order to record respectively a present stock of products (or goods in stock) by storing the occupancy information in the communication device 630. Alternatively, the occupancy determination can be effected only at fixed points in time or in response to a request. For example, a stock-taking point in time may be fixed, at which the storage system may perform an automatic stock-taking (or inventory), i.e. an occupancy detection of all compartments TB.
A remote maintenance program module 720 may be stored on the communication device 630, which module may be addressable via the network, and which can perform maintenance processes directly on the storage system. The remote maintenance program module may be configured for example such that upon (or in response to) the receipt of a command over the network the sensor system 200 may be activated such that the occupancy information of a compartment TB specified in the command by the statement of a corresponding address may be detected, and based on the occupancy information an occupancy information signal may be generated, which may be sent via the network.
The communication device 630 may be configured to be connected to a computer 730 via a local connection so as to visualize an occupancy plan 700 stored in the communication device 630 on a user interface of the computer.
The communication device 630 may further have a setup mode, wherein an occupancy of the storage system 600, which occupancy may have been measured by the sensor system 200 in the setup mode, can be stored as an occupancy plan, wherein the occupancy plan may comprise in particular the goods type assigned to each compartment TB and an occupancy threshold value assigned to this goods type, which threshold value may be given by the occupancy measured by the sensor system 200.
The shelves 310 may have openings in the filling direction of the compartments TB, in particular in the direction of the slope so as to possibly enable a signal receipt and/or a signal emission by the sensor system 200, wherein the sensor assemblies 100 of the sensor system 200 may be located below the shelves 310, and may be covered by a film, which may have been applied on an upper side of the shelf 310 in the filling direction, and which may cover the openings.
The film may concern for example a plastic film, in particular a PVC film, wherein the plastic film may be transparent in particular in the range of a frequency of the signal receipt and/or the signal emission.
