DE102012100354A1 - Method for regulating and controlling of a manual consignment based on an order by an order picker in a warehouse, involves containing quantities of a stored good and the coordinates of the goods in a database within the warehouse - Google Patents

Abstract

The method involves containing quantities of a stored good and the coordinates of the goods in a database within the warehouse. An instruction for route guidance is determined and issued on the basis of a rough location of the order picker and on the basis of a fine tracking for execution of an order for consignment after a demand of an order picker. An accurate location of the order picker is activated with approach to a new destination. Radio frequency identification tags are used for tracking and Wireless local area network connection is used for transferring data. An independent claim is included for a system for regulating and controlling of a manual consignment based on an order by an order picker in a warehouse.

Description

The present invention relates to a method for controlling and controlling a manual picking and a corresponding system.

Various approaches to methods of controlling, controlling and monitoring manual picking operations in warehouses are known in the art. The methods meet the requirements that they operate in a closed building and in an environment with a variety of metallic objects or liquids. Methods such as pick-by-light and pick-by-voice have been used productively for some time now. Today, they are an integral part of the product portfolio of all commercial warehouse equipment suppliers. The two mentioned technologies provide information about the storage location of the next product to be taken or also about the quantity. The user is only able to move on to the next job after processing and acknowledging his tasks.

PbV befindet sich derzeit bei verschiedenen Lehrstühlen und Unternehmen aber noch im Entwicklungsstadium. Operative Anwendungen sind bislang nur vereinzelt im Rahmen von Laboranwendungen und Feldversuchen bekannt. PbV nutzt zur Anzeige die Technik der Augmented Reality, kurz AR, bei der das Bild der realen Umgebung mittels Überlagerung mit virtuellen Informationen angereichert wird, z.B. durch Einsatz von Bildschirmen, Datenbrillen oder einer Laserprojektion auf die Netzhaut. Zur Bestimmung der exakten Position eines Objektes und dessen Bewegungsrichtung bzw. Tracking des Kommissionierers und dessen Kopfstellung zur Identifikation der Blickrichtung sind unterschiedliche Ortungstechnologien bekannt. Es handelt sich beispielsweise um: The Pick-by-Vision (PbV) process builds on this logic and supplements it with the functional scope of the controlled routing up to the destination storage compartment - comparable to GPS in road traffic. It combines the following functionality:

• - Optical transfer of picking information (destination address, article number, number of pieces, etc.)
• - path display
• - Marking the required storage compartment
• - Capture of user input

PbV is currently still in the development stage at various chairs and companies. Surgical applications have so far been known only occasionally in the context of laboratory applications and field trials. PbV uses the Augmented Reality technology, AR for short, in which the image of the real environment is enriched with virtual information by means of overlapping, eg by using screens, data glasses or a laser projection on the retina. In order to determine the exact position of an object and its direction of movement or tracking of the order picker and its head position for identifying the line of sight, different location technologies are known. For example:

a) Detecting the position and direction by means of fixed cameras in the storage environment (see: http://www.youtube.com/watch?v=jh0MK8F8iG4&lr=1&user=augmentedrealitytum)

The procedure calculates the position and direction of the order picker by detecting the distance and spatial position of tracking markers in relation to permanently installed cameras. The markers have the shape of balls and are attached to the data glasses of the order picker. The disadvantage is the high investment costs for the required cameras, especially for use in large storage areas. Difficulties also arise from the required lighting conditions. Due to the unstable arrangement of the tracking markers, whose exact positioning is a fundamental prerequisite for the procedure, frequent repairs are inevitable.

b) Detection of Position by Radio Frequency Identification (RFID):

By applying the methods of triangulation, the position of the transmitting tag can be calculated upon reception of the signal of an RFID tag by at least three receiving antennas, cf. Radio relay for locating aircraft. Alternatively, by using tags with a low transmission range, zones can also be identified, cf. Constellation in the field of mobile masts, and thus roughly determine the position of a receiving antenna. Due to the size and weight of the hardware, the methodology is particularly applicable for the localization of storage and retrieval equipment and narrow aisle truck. So far, in the field of manual picking, it is known only for theoretical reasons. The accuracy of the positioning depends on the distance of the installed RFID tags. The orientation of the observer can not be ascertained. When approaching from several order pickers, interference occurs. Liquids and steel lead to different disturbance patterns.

c) Recording the position using augmented reality markers:

The use of mobile cameras to detect permanently installed augmented reality or AR markers allows a further form of position determination. For this purpose, the size and the image distortion of an AR marker are used to deduce the relative position of the camera to the marker. If the camera is carried along by the order picker and the orientation of the camera corresponds to the direction of view of the order picker, this also results in its position and orientation. However, since it is not possible to install AR markers in warehouses due to the often shallow gaps, the application is limited.

d) detection of the position by means of image recognition:

The use of a mobile camera to capture the viewing angle of a picker allows by comparing the captured image with stored in a database images another form of position determination. However, the required computing power on the available systems proves to be problematic in practice. In addition, as the storage environment undergoes continuous change, a permanent update of the reference image database is required. The latter can not be ensured in practice.

e) Detecting the position by means of acceleration sensors:

Starting from a clearly identified starting position and orientation, the position change is detected by means of an acceleration sensor, translational and rotational. By integrating the detected accelerations, the changed position and orientation can always be calculated. However, the accuracy of commercial acceleration sensors does not allow sufficiently accurate data for the intended application.

From the patent DE 102 15 885 A1 For example, an automatic process control method is known in which a real work environment is detected by means of a dedicated device. The goal here is to compare recorded real work processes with at least one given virtual work process and to trigger automatically controlled follow-up processes.

• – Die Verfahren ermöglichen nicht den Einsatz von mehreren parallel arbeitenden Kommissionierern.
• – Die Verfahren können nur durch einen hohen apparativen Aufwand betrieben werden. Dies erfordert einen großen Installationsaufwand und hohe Investitionskosten insbesondere für den Einsatz in großflächigen Lagern.
• – Der Apparaturen sind nicht auf die Voraussetzungen im operativen Lagerbetrieb ausgelegt und lassen große Ausfallzeiten erwarten, ausgelöst insbesondere durch mechanische Erschütterungen, Staub, Feuchtigkeit, Temperaturschwankungen.
• – Die reale Lagerumgebung liefert keine idealen Einsatzvoraussetzungen, insbesondere wegen der Anwesenheit von Stahl, Flüssigkeiten, schlechte Lichtverhältnisse etc.
• – Die Rechenleistung gegenwärtig verfügbarer mobiler Prozessoren ist nicht ausreichend oder erfordert zudem einen ständigen Abgleich mit einer zentralen Serveranwendung. Erschwerend wirkt sich aus, dass aufgrund der inhomogenen Lagerumgebung eine durchgängige WLAN-Abdeckung nicht garantiert werden kann.
• – Die erforderliche Prozessorlaufzeit führt zu einem hohen Energiebedarf und geringer Akkulaufzeit.
• – Die erforderliche Genauigkeit in Bezug auf Position und Orientierung kann für die angestrebte Anwendung nicht dauerhaft gewährleistet werden.
• – Die Verfahren erfordern lange Lern- und Einarbeitungszeiten.

All known methods described above by way of example are therefore only of limited suitability for operational use in the field of picking. In summary, the following deficiencies can be determined for the individual or in part all methods known from the prior art:

• The methods do not allow the use of several parallel order pickers.
• - The process can only be operated by a high expenditure on equipment. This requires a large installation effort and high investment costs, especially for use in large-scale camps.
• - The equipment is not designed to meet the requirements of operational storage operations and can expect large downtime, triggered in particular by mechanical shocks, dust, moisture, temperature fluctuations.
• - The real storage environment provides no ideal conditions of use, especially because of the presence of steel, liquids, poor lighting conditions, etc.
• The computing power of currently available mobile processors is insufficient or requires constant synchronization with a central server application. A complicating factor is that due to the inhomogeneous storage environment a consistent WLAN coverage can not be guaranteed.
• - The required processor runtime leads to a high energy requirement and low battery life.
• - The required accuracy in terms of position and orientation can not be permanently guaranteed for the intended application.
• - The procedures require long learning and training periods.

The aim of the present invention is essentially to remedy the deficits described and thus to tap significant cost and efficiency potentials in storage operation. This object is achieved by the features of claim 1, characterized in that for processing a picking a coarse tracking method in the first step may even be sufficient and thus can be worked fault tolerant, as below with reference to the figure of 7 is described. The employee then receives instructions based on a fine tracking procedure only when the order picker approaches the target. This allows the use and combination of different tracking technologies in the form of a two-stage or multi-stage tracking method while increasing positioning accuracy over several stages. If the arithmetic work no longer takes place in real time, but quasi bit by bit, then low-performance processors are sufficient. A corresponding adaptation of a method thus leads to saving on hardware or to reducing the costs for the hardware due to lower computing requirements and a reduced amount of energy. As a consequence, a need for battery performance is lower, which also leads to weight and cost savings with extended service life between charging cycles of the respective energy storage, see. also below 8th , Thus, the process can also run decentralized and is not dependent on the permanent communication with a central server application.

In an alternative embodiment of the invention, the employee is initially only a navigation routine available to achieve a new goal if needed. As the new target approaches, a coarse tracking of the employee is activated, on the basis of which a more delicate, progressively accurate route guidance and targeting intervenes. The unnecessary routine shuts off when not in use to conserve hardware and reduce the power consumption of a respective portable part of the overall device. This procedure can be used with mobile hardware work, which otherwise does not provide sufficient resources for a constant calculation of the exact position. Corresponding hardware with the necessary technical equipment and performance is already available today at an economically competitive price. Furthermore, the consumption of electrical energy stored in a rechargeable battery is also reduced in this way, which allows extended system operating times and a weight-reduced execution of the hardware.

An output of a respective navigation can be visually on head-mounted displays, mobile data acquisition devices - short MDE - with barcode scanners, portable PCs, tablets or acoustically via headphones or speakers and / or other mobile electronic devices.

• - Provided at the order picker mobile unit for transmission and display of information for the route guidance. Further developments of a corresponding system are specified in the claims dependent on claim 7.

Throughout the various figures, the same reference numerals are always used for the same elements or method step. Without limiting the invention, only one insert for picking in a parts store will be shown and described below. However, it is obvious to the person skilled in the art that adaptation to a high-bay warehouse using corresponding lifting devices is possible in the same way.

1 represents a known from the prior art starting situation in which a picker K in a warehouse W a relevant order A processed. The warehouse W has an electronic inventory management B in which quantities of a respective stored product and also the coordinates R of the respective goods within the warehouse W are contained in a database. Correspondingly, coordinates of a commissioned target product R (A) are also known. Marking marks M, indicated here as RFID chips, serve for the orientation of the order picker K and / or the electronic control system for order picking as well as locating or tracking the order picker K without contact via electromagnetic waves by specifying coordinates R (K). In a data-processing device, the coordinates R (K) of the picker K and the coordinates R (A) of the destination goods to be picked according to order A are processed to determine a destination path. This target path can be optimized under further specifications, in particular the specification of a shortest path or an optimum path of the order-taker K on the basis of special parameters. The order-picker K carries a mobile equipment D with him for the transmission of the corresponding guidance for the most accurate possible adherence to a path a respective order A with a route guidance to coordinates R (A) and also transmitted eg with respect to a respective number of pieces and the order picker K displayed according to and / or announced, here indicated as data glasses.

According to the invention, it should now be taken into account in such a method sequence that when a job A arrives, a position of the order picker K does not have to be known or not precisely. Knowing the coordinates R (A), the order picker K receives only a rough target. An approach of the order-picker K to the coordinates R (A) of the target goods to be picked according to order A by a means I for determining the location of the order-picker K or his coordinates R (K) becomes a progressive refinement of the route guidance of the order-taker K used. In this case, in one embodiment of the invention, such a refinement in the event of a timeout trigger, ie in particular in the event that a picker K has lost the orientation or a new target for the order picker K should have been incomprehensible and the order-picker K accordingly by his estimated or higher resolution determined location coordinates R (K) should hardly or not to the coordinates R (A) of the target goods should move. In this way, a transition from a state of inaccurate position knowledge or even without locating the picker K to a regulation for fine adjustment of the route guidance is thus created. The advantages of this approach will be discussed in detail below.

The means I for more or less accurate determination of location coordinates R (K) of the order picker K are arranged here in the mobile unit D, so that this information can be sent by each order picker K directly to the management system. Each order picker K knows his position in sufficient accuracy via his mobile unit D, but does not have to report it continuously to a control center. Thus, problems of shielding or shading secondary importance, also extended by appropriate messages in time intervals an operating life of the portable energy storage or batteries.

In addition to the use of WLAN provided below, in data transmission technology when using several order pickers K, other electromagnetic data connections and adequate channel separation measures are also known, e.g. TDMA, FDMA, CDMA. Alternatively, however, such means I can also be provided in a stationary manner at a location which is always sufficiently electrically reachable, which would have the advantage of a simplified supply of electrical energy. Alternatively, such means I may also be distributed decentrally in the warehouse W, the former solutions being more cost-effective, the latter providing greater redundancy.

2 shows as a block diagram equipment D of a picker K, which he carries with him, so as a mobile unit D. Here, the mobile unit D includes the functional modules mobile WLAN antenna 7 with coupled, mobile computing unit 8th , an output unit 9 formed in this example as a head mounted display, an input unit 10 , here as a microphone for communication with the order picker K formed and finally a detection unit 11 in the form of a camera for communication with higher-level tracking system. The design and number of output units 9 , Input units 10 as well as registration units 11 may vary per application in each case.

• – einer Wareneingangszone 1, welche zur Annahme angelieferten Materials dient,
• – einem Packbereich 2, in welchem die kommissionierten Kundenaufträge auf den Versand vorbereitet werden,
• – einer Warenausgangszone 3, in welcher die Kundenaufträge auf Abholung warten sowie
• – dem Regalbereich, in dem die Waren gelagert sind. Der Regalbereich besteht aus Regalreihen 4 und ist strukturiert in Gassen. Er stellt den flächenmäßig größten Anteil an der Gesamtlagerfläche dar.

The order picker K is located in a storage environment W, as in the figure of 3 outlined. It usually consists of

• - a goods receipt area 1 , which serves for the acceptance of delivered material,
• - a packing area 2 in which the picked customer orders are prepared for shipment,
• - a goods issue area 3 in which the customer orders are waiting for pickup as well
• - The shelf area in which the goods are stored. The shelf area consists of rows of shelves 4 and is structured in alleys. It represents the largest proportion of the total storage area in terms of area.

The sketch below shows the local arrangement of AR markers 5 , which are attached to the floor or the shelves. A warehouse environment is exemplary in 3 shown. The markers are used only at longer intervals for recalibration and coarse navigation, ie navigation without exact location, which in turn lowers the number of markers required and thus keeps the installation costs low.

At the beginning of a picking process, the order picker K usually stays in the packing zone 2 , Goods receipt area 1 or goods issue area 3 on. If he is ready to accept the order, then he runs in 4 as a flowchart shown communication process between the central warehouse management software, the mobile unit D according to 2 and the order picker.

The essential process step to start the picking task is the assignment of the symbols to the AR markers 5 , which is decentralized on the mobile unit. The assignment is made purely from the logic where the target address of the next picking order to be executed is located. Is the destination address in Alley? 2 , so get the AR markers 5 out 3 for example, the in 4 assigned symbols, here symbols in arrow form. The marker closest to a respective target zone 6 is assigned a different symbol; in the 5 shown as unfilled circle.

Regardless of the actual location of the order picker at the time of the transfer of the picking order can be based on the the AR markers 5 assigned symbols are read the navigation direction. Only when the camera as the detection unit of the mobile unit D, the unfilled AR marker 6 In a minimum size, the system switches to the tracking functionality. The tracking system works, for example, on the basis of image recognition. For this purpose, when the order picker looks at the shelves in the immediate vicinity of the destination address, the barcodes installed on the shelves are read out. Based on the read-out information, the destination address is optically marked in the output unit, as known in the prior art in the communication and data generation for the use of augmented reality, short AR.

The two pictures of the 7 and 8th show as detailing the 6a to 6e How to use this application to increase fault tolerance and realize investment reduction and energy savings.

The reduced energy requirement due to the interval-like communication is in 9 represented as a comparison of the communication load on the basis of the time course of the current flow i (t) and the location accuracy Δ (t) in a known system and in a system according to the present invention. Likewise, the course of the accuracy of the location determination can be recognized there, which according to the communication is subject to a fluctuation. In this case, by adequately setting the communication interval ensures a sufficiently low accuracy, which is then switched according to the above disclosure only when approaching a target coordinate then for a comparatively short period of time to a higher positioning accuracy.

In a method according to the invention, it does not necessarily have to be a commissioning employees of a warehouse company. Thus, alternative embodiments are conceivable, some of which are briefly outlined below:

Example 1: Goods receipt

When storing goods in storage units, it must be ensured that the goods can be easily recovered if necessary. For this purpose, the stock-keeping software or warehouse management system, in short LVS, assigns the goods a specific storage compartment. The presented application can also assist in finding the destination address in this case.

Example 2: Multilevel Tracking System

As part of a research process, the Munich University of Applied Sciences has developed an RFID-based tracking system that supports manual order picking by picking trolleys. It assumes the function of rough navigation to an accuracy of +/- 1 m. The preventive collision control and the avoidance of awarding the same destination address to independent order pickers at the same time, in particular for congestion avoidance, are advantageous. Tracking in the near range could be done using an integrated in the mobile unit acceleration sensor. The mobile unit in this case consists of two acquisition units 11 ,

Example 3: Customer guidance in the supermarket

The process of manual picking is transferred to other areas of daily life. Thus, the present embodiment of the invention is used to guide the customer of a supermarket to the goods desired by him. As output unit 9 In this embodiment, a display permanently installed on the shopping cart is used. This can also simultaneously as input unit 10 be used by the customer to select the desired product from the range of goods of the supermarket or to confirm the removal. Optionally, the operator of the supermarket has the opportunity to alert the customer to special offers, for example, should he stay in the immediate vicinity of the product. Alternatively, this can be coupled to a selection by the customer to a destination guide.

Example 4: Material supply and disposal in the production area

The present application can also be used to support the process of goods supply and emptying in the manufacturing area. In this case, special workstations or material buffers are used as the destination address. Existing forklift guidance systems can be reduced in complexity and made less expensive. An insert is due to the low weight of the mobile unit but also e.g. for manual material feeding, by means of other lifting devices or tugger trains feasible.
