Description

Information indicator and logistics management system including it {Information indicator and logistics management system including it}

The present invention relates to a logistics management system, and more particularly, to an information indicator displaying product information to be picked at different locations or to display information on products to be assorted to different locations, and logistics including the same. It's about the management system.

As a logistics management system to support the efficiency and accuracy of logistics work in a logistics center, a system for product picking called DPS (Digital Picking System) and a system for product distribution called DAS (Digital Assorting System) are adopted. .

DPS installs indicators on shelves where products are stored for each product, and displays product information to be picked from the corresponding shelf, so that the picker picks the product based on the displayed product information. This DPS is suitable for a stock type distribution center and has the advantage of being able to manage inventory at the same time since indicators are installed for each product.

On the other hand, DAS installs a display on the shelf where each shipping destination box is placed, and displays the information of the product to be contained in the box placed on the corresponding shelf, so that the operator sees the displayed product information and distributes the product. This DAS is suitable for pass-through distribution centers that do not hold inventory, and enables automatic inspection while carrying out total picking and distribution by shipping destination.

The exemplified DPS and DAS all display the picking quantity or dispensing quantity of the product through the information indicator, and the operator performs the picking or distributing work based on this. A typical information indicator includes a 3-digit or 5-digit quantity display LED displaying the quantity for picking or distribution of goods, that is, a FND (Flexible Numeric Display) display unit, and an ID switch for setting the ID (IDentifier) of the display unit. and a correction switch for correcting and inputting the amount of work, a completion switch for inputting the completion status of the task, and a completion lamp for displaying the completion status of the task.

In the system using the above-described information display device, when the position of a product is changed, a worker manually issues a label for the corresponding product and attaches it to a shelf where the product is loaded or a shipping destination box is placed. That is, in the logistics management system using the above-described information indicator, there is a disadvantage in that a worker has to cumbersomely issue and attach a label whenever product-related information or shipping information is changed, and consequently, product picking or distributing work in a logistics center can be performed quickly and accurately. There is a problem in that productivity is lowered due to inefficiency that cannot be treated.

Furthermore, shelf for product loading used in general distribution centers has a multi-layered structure, and since each layer must be equipped with an information indicator displaying product-related information, a new improvement plan for efficient use of resources is required. A method that can be used in both DPS and DAS is needed.

First, FIG. 1 illustrates a configuration diagram of an information display device 200 according to an embodiment of the present invention and a logistics management system including the same. The illustrated logistics management system includes a logistics management server 100, one or more switching hub routers ( 110), a plurality of access points (APs, 120), a plurality of information displays 200 attached to shelf frames on which products are loaded, and one or more smart carts 300.

The logistics management server 100 inputs and stores product-related information such as product inventory information, shipper-related information such as customer order information, and various work status information, and generates information such as product loading, movement, and picking instructions. to play the role of output/propagation.

More specifically, the logistics management server 100 generates and outputs picking information for each information display to be delivered to the information display 200 according to an embodiment of the present invention, and may generate and output distribution information for each information display. . In addition, the logistics management server 100 not only updates the inventory remaining amount of the product according to the work completion information transmitted from each information indicator 200, but also controls the shipment management of the product.

Meanwhile, the switching hub sharer 110, which is one of the network equipment, transmits and receives various information between the logistics management server 100 and a plurality of access points 120, and the access point 120 transmits the information through the switching hub sharer 110. The selected information, for example, picking information or distribution information for each information display unit, is wirelessly propagated to the information display units 200 located within a communicable area. The information display 200 and the access point 120 may use ZigBee low power wireless communication technology as well as other known short-range wireless communication technology.

Hereinafter, among the above-described configurations, information displayed on the information display device 200 and a process in which a worker picks or distributes products by using the information will be described in more detail.

FIG. 2 illustrates an attached state and a display screen of the information display device 200 in FIG. 1, and FIG. 3 illustrates a block configuration diagram of the information display device 200 in FIG.

As shown in FIG. 2, the information indicator 200 attachable to the shelf 130 on which products are loaded visualizes picking information for picking products loaded on each of the multi-layered (longitudinal) shelves as a picking table for each floor. and display it

As shown in FIG. 2, the floor-specific picking table includes information on the floor where the product is loaded (1, 2, 3, 4, 5, ..), product identification information (product code) for each floor, and picking in each floor by order. It includes quantity information (first quantity, second quantity, tertiary quantity,..) and stock quantity information loaded on each floor, and these information are m×n (m is the number of rows, n is the number of columns) ) visualized as a picking table for each floor.

The configuration of the information display 200 for visualizing and displaying the above-described layer-by-floor picking table will be further described below. First, as shown in FIG. 3, the information display 200,

A wireless communication unit 210 for wirelessly receiving picking information for each information indicator for picking products loaded on each shelf of the multi-layer structure;

A display unit 250 for displaying picking information for each information indicator;

A button unit 220 including an end button for inputting the end of the picking operation;

An information reception indicator light 230 for indicating whether there is an operation,

A memory for storing information display device identification information is included, and a controller 240 extracts only picking information including the information display device identification information stored in the memory and displays the extracted picking information on the display unit 250 .

The control unit 240 extracts the floor information on which products are loaded, product identification information for each floor, quantity information to be picked in each floor by order, and inventory quantity information loaded in each floor from the picking information, and extracts m×n It is visualized and displayed as a picking table for each floor in the form of (m is the number of rows, n is the number of columns).

The control unit 240 may further include the total quantity, which is the sum of quantity information to be picked in each floor for each order, as one column in the picking table for each floor to visualize it, and may display the location matching information where the information indicator 200 is located as one column. As a column of , it may be further included in the layer-by-layer picking table to be visualized. Furthermore, a barcode indicating floor information (location) on which products are loaded may be further displayed together with the product identification information for each floor.

In addition, if there are many orders to be picked in each floor, the control unit 240 first displays only a part of it as a table when it cannot display all of them, and in response to an operator's command, it can sequentially form a table and display information on the remaining orders. . For example, the quantity information to be picked for each floor by order is displayed in different columns in the picking table for each floor, but if the order to be displayed exceeds the specified value (for example, the third order), only a part of the priority order (within the third order) is displayed. It can be displayed in different columns, and the rest that are not displayed can be displayed whenever a column of the end button 225 is input. However, it is assumed that the input is a continuous input within 2 seconds. This short input time can be changed and set, and a continuous input exceeding 2 seconds will be referred to as a long input.

Accordingly, the control unit 240 recognizes that the picking operation is finished when the end button 225 is pressed, and wirelessly propagates the end of the picking operation to an external device (logistics management server).

For reference, when information is received from the logistics management server 100, the control unit 240 displays the status by blinking the information reception indicator light 230, and when the information reception is completed, notifies the operator of the start of the picking operation. In order to do so, the information reception indicator light 230 is turned on and controlled. In addition, when the picking operation is completed, the lighted information receiving indicator lamp 230 is controlled to be turned off and power consumption is minimized by entering a standby state (which may be referred to as a standby mode) for receiving information.

If the above-described information display 200 is used as an information display for DAS, the control unit 240 receives distribution information for each information display unit for distributing products to shipping boxes located in the vertical direction, and displays it on the display unit 250. indicate,

As shown in FIG. 6, in the distribution information, the floor information of the shipping box to contain the product, the distribution destination information for each floor and customer location information, the quantity information to be distributed to each floor by order, and the stock quantity of the product to be distributed to each floor Information is extracted and displayed as a distribution table for each floor in the form of m×n (m is the number of rows and n is the number of columns).

That is, the information display 200 according to an embodiment of the present invention can be used as a combined information display for DPS and DAS, and can also be used exclusively for DPS and DAS. Separate tag information for distinguishing DPS and DAS may be included in information transmitted from the distribution management server 100 and transmitted.

If it is a logistics management system including the smart cart 300, the information indicator 200 may further include a short-range wireless communication unit (Bluetooth module or wifi module) for transmitting and receiving information with the smart cart 300.

Meanwhile, the logistics management system according to an embodiment of the present invention may have the smart cart 300 as one component. Such a smart cart 300 may have an appearance as shown in FIG. 4 .

The smart cart 300 is intended to provide convenience so that the operator does not have to operate the end button 225, and furthermore, the information display 200 displays information on the quantity to be picked in each floor by order in a plurality of columns. This is a configuration that can be used as a solution to solve this problem because there is a possibility of confusion about which order product was being picked during product picking.

To this end, the smart cart 300 includes a picking box 310 divided into a plurality of zones, a product identification information reader (for example, an RFID reader) for obtaining picked product identification information, and a logistics management server 100. It is preferable to mount a computer system for workers including a wireless communication unit for receiving work instructions from. Such a computer system may be a tablet PC, a notebook computer, or a computer system integrated with the smart cart 300 .

The computer system integrated into the cart includes a display unit for displaying work instructions, an interface unit capable of interfacing data with an RFID reader corresponding to a product identification information reader, and a short-range communication module capable of transmitting and receiving information with the information display unit 200 ( Wi-Fi module or Bluetooth module), a wireless communication unit capable of transmitting and receiving information with the logistics management server 100 through a wireless communication network (preferably interpreted as a concept including a mobile communication network), operation of a computer system (eg, product It may include a control unit capable of overall control (such as removing product identification information obtained from the identification information reader from the work instruction displayed on the display unit).

Since the smart cart 300 including the configuration described above can flash and display the product that the worker needs to pick in the work order, the worker sees the picking information of the blinking order and picks the product to pick the product in the picking box 310. ), there is no need to remember which order product was being picked during product picking.

In addition, the control unit of the operator's computer displaying the work order transmits the fact to the information indicator 200 through short-range wireless communication (Bluetooth communication) when all products to be picked in a specific order have been picked, so that the operator can The control program of the smart cart 300 and the information display 200 may be coded so that the end button of the display 200 can be obtained by short input or long input.

Hereinafter, an operation of the information display 200 according to an embodiment of the present invention will be described in detail with reference to FIG. 5 . For reference, FIG. 5 illustrates an operation flowchart of the information display 200 in FIG. 1 .

Referring to FIG. 5, first, the logistics management server 100 provides picking information (floor information (location code), product name, product code, Stock quantity, total picking quantity, etc.) are generated and wirelessly propagated through the switching hub router 110 and the access point (AP, 110). The picking information for each information indicator includes identification information of the information indicator.

Accordingly, each information display unit 200 can selectively receive only the picking information for each information display unit including its own identification information (step S10). The control unit 240 of the information display 200 may inform the outside of the information reception state by controlling the information reception indicator 230 to blink when receiving picking information for each information display including its own identification information.

When the picking information for each information indicator is received, the control unit 240 displays the information on the floor in which the product is loaded from the received picking information, the product identification information for each floor, the quantity information to be picked on each floor for each order, and the information on the quantity to be picked on each floor for each order. As shown in FIG. 2, the inventory quantity information is extracted (step S20) and visualized and displayed as a picking table for each floor in the form of m×n (m is the number of rows, n is the number of columns) as shown in FIG. 2 (step S30). Subsequently, the control unit 240 propagates that there is a picking operation to be performed to nearby workers by controlling the lighting of the blinking information reception indicator light 230 (step S40).

A worker confirming that the information receiving indicator light 230 is turned on is located in front of the information indicator 200 with a movable cart containing picking products (a product loading zone is divided). Since the picking table for each floor as shown in FIG. 2 is displayed on the information display unit 200, the worker sequentially picks products to be picked by order in each displayed floor and puts them in the cart. For example, as shown in FIG. 2, the worker picks 14 products located on the 3rd floor shelf, 2 products located on the 4th floor shelf, and 5 products located on the 5th floor shelf during the first operation, and removes the compartmentalized cart. 1Put it in the loading zone. Subsequently, as a secondary operation, nine products located on the first-floor shelf, one product located on the second-floor shelf, and one product located on the fourth-floor shelf are picked and placed in the second loading zone of the divided cart. Subsequently, as a third operation, one product located on the first floor shelf and one product located on each of the second to fourth floor shelves are picked and placed in the third loading zone of the divided cart.

Subsequently, the worker inputs the end button 225 step by step to check whether there is an additional amount of work that is not displayed. Accordingly, if there is an end button input (step S50), the control unit 240 checks whether the input is a single input indicating a continuous input within 2 seconds (step S60).

If it is determined as a single input, the control unit 240 checks whether there is information that has not yet been displayed as quantity information to be additionally picked for each order (if there is no information, it is possible to induce a field input by maintaining the existing display state as it is) for each order displayed Quantity information is changed (step S70). That is, previously displayed 1st to 3rd quantity information is removed, and 4th and 5th quantity information that were not previously displayed are newly displayed.

Accordingly, the worker completes the picking up to the 5th quantity by picking the product based on the 4th quantity information again from the corresponding floor and putting it in the partitioned 4th loading zone. When the 5th operation is completed, it can be recognized that there is no more quantity to be picked through the third column (the column where the 3rd quantity was displayed) is marked blank. Accordingly, the worker inputs the end button 225, so that the control unit 240 recognizes that the picking operation has ended and sends information or a message indicating the end of the picking operation to the upper logistic management server 100 through the access point 120. ) After radio waves (step S80), the information receiving indicator lamp 230 is controlled to turn off (step S90).

The distribution management server 100 receiving the end of the picking operation updates the inventory quantity for each floor, and if there is a task to be additionally picked, additionally generates picking information for each information receiver as described above to display the lower stage information indicator (200 ) is transmitted again.

Meanwhile, workers who have completed the picking work move to the shipping area with the cart and post-process the products so that they can be shipped.

As described above, the information indicator 200 according to an embodiment of the present invention has information related to products loaded on each shelf of a multi-layer structure and quantity information to be picked for each order among products loaded on each floor. Since it is visualized and displayed as a picking table for each floor in the form of m×n at once, picking information of products located on multiple floors can be displayed at once with only one information indicator 200, as well as multiple pickings. Information that needs to be done can be displayed sequentially according to the operator's command, resulting in the effect of lowering the cost of building a system for logistics operation management.

If the cart used by the worker is the smart cart 300 shown in FIG. 4, the worker picks the product through a product identification information reader (RFID reader) or reads the product picked automatically by the reader embedded in the picking box. can perceive In this case, since the control unit of the worker computer can remove the product identification information obtained from the product identification information reader from the work order displayed on the display unit, when the picking of products belonging to all orders displayed on the information display unit 200 is completed, the end button ( 225) is transmitted to the information display unit 200, so that new picking information for each order can be displayed on the information display unit 200. When the picking is completed, the same information as inputting the end button 225 is transmitted to the information display 200, which is inconvenient for the operator to operate the end button 225 provided in the information display 200. It has the advantage of being able to remove the ham.

In the above embodiment, the process of displaying the picking information for each floor available in the DPS on the information indicator 200 to allow the worker to perform product picking has been described. The process used in the DAS will be further explained by displaying it.

FIG. 6 illustrates another display screen of the information display 200 in FIG. 1 .

As shown in FIG. 6, the control unit 240 of the information display unit 200 transmits distribution information for each information display unit to the shipping boxes placed on each shelf located in the vertical direction (multi-layer structure) through the wireless communication unit 210. Received through ) and displayed on the display unit 250,

In the distribution information, the floor information (1st, 2nd, 3rd, etc.) of the shipping box in which the product will be contained, information on the distribution destination for each floor (for example, store name or customer name), and customer location information (barcode marking of the location) ), extract quantity information to be distributed to each floor by order, and inventory quantity information of products to be distributed to each floor, and visualize it as a distribution table for each floor in the form of m × n (m is the number of rows, n is the number of columns) display

Through this distribution table for each floor, the worker can pick up the quantity of each floor indicated on the distribution table for each floor and put it in the shipping box provided on the floor while carrying a specific product in a cart without a separate slip. Compared to the previous method of distributing products by outputting, it is possible to increase work efficiency and eliminate the inconvenience of a worker having to print and carry a slip. It is convenient to easily identify shipping boxes to distribute products.
