Before explaining the operation example of the DPC 1 according to an embodiment of the present invention with reference to FIGS. 1 to 4 in detail, the loading plate (16, 17) of the DPC 1 in FIG. As described above, it is assumed that the cartons CBX1 to CBX5 for storing the picked goods classified by the destination are stored.

The power supply unit 42a shown in FIG. 2 is a battery housed in the battery box 42 of FIG. 1, and supplies an operating power supply voltage to each unit shown in FIG. 2. When each unit shown in FIG. 2 is operated by the power supply of the power supply unit 42a, the controller 40 searches whether the shipment information reception mode is performed in step S10 of FIG. If it is not the shipment information receiving mode in step S10 and performs the corresponding function in step S11, if it is determined that the shipment information receiving mode control unit 40 through the RF transmitter and receiver 34 in step S12 (not shown) ) Shipment information is received and stored in the memory 36. Here, the shipment information means a list of ordered products by customer (shipping address). For example, it is a list of accounts, ordered products and number. The RF transmitter / receiver 34 may use a wireless transmitter / receiver such as a wireless LAN or Bluetooth capable of short-range wireless communication.

The controller 40 of the DPC 1 that has received the shipment information in step S12 searches for whether the picking mode is switched in step S13 of FIG. 2. For example, if it is determined that the picking button is selected from the UI 24 and the picking mode is determined, the shipping information stored in the memory 36 is sorted in step S14 and the information is stored in the memory 36 to pick the picking mode. Switch to The sorting of the shipment information means sorting the list of the clients in a certain order based on the goods ordered by the clients, and the sorting of the shipment information is to speed up picking of the goods. In addition, the control unit 40 outputs the sort information stored in the memory 36 to the monitor 20 to display the state.

The controller 40 sorting the shipping information sets a storage position corresponding to the shipping information sorted in step S15. For example, the picking goods of the first delivery address (contractor) are stored in the cartons (CBX1, CBX2) loaded on the upper loading plate 17 of FIG. It is set to store in the cartons (CBX3 to CBX5) loaded in 16). For this setting, as shown in FIG. 4, a bar code tag BCT is inserted into the cartons CBX1 to CBX5, and the information is read by the scanner 22 and transmitted to the controller 40. By setting the process S15, the control unit 40 controls which goods are loaded on the cartons CBX1 and CBX2 loaded on the top loading plate 17 of the cart 10 or the bottom loading plates 16, CBX3 to CBX5. ) To see if it should be stored.

Thereafter, the controller 40 accesses the location map for the first product of the shipment information sorted in step S16 from the memory 36 and displays it on the display unit 20, and reads the output of the scanner 22 and attaches it to the product. Search whether barcode information, that is, product information, is input.

In this state, the picking operator moves to the location indicated on the monitor 20, picks the goods loaded in the storage bin of the pallet, and scans the barcode information of the picked goods with the scanner 22. ) May know which goods are picked by the output of the scanner 22. After the picking operator scans the bar code of the goods and places the picked goods on the weighing plate of the load cell 26, the load cell 26 provides the control unit 40 with weight information that weighs the weight of the goods placed on the weighing plate. .

The controller 40 inputs the weighing information of the picked goods provided from the load cell 26 in step S18 and divides the weight value of the picked goods into the unit weight value of the scanned goods in step S19. Determine if it is picked. At this time, the controller 40 displays the result of comparing the number of the picked goods and the number on the sorted shipment information list on the monitor 20, and drives the voice output unit 38 to display the number of picked goods. To guide.

Therefore, the picking worker picks the corresponding product at the location by picking information such as the shipment product, the shipping account, the number of picking, and the location map information of the product displayed on the monitor 20, and checks the weight in the load cell 26 to be necessary. The number can be picked accurately.

The controller 40 which grasps the number of goods picked by the above processes is carried out in the cartons CBX1 to CBX5 in which the goods picked in step S20 are loaded on the loading plates 16 and 17 of the cart 10 shown in FIG. ), The storage indicator 28c is turned on to indicate which one of the boxes should be stored, and then it is checked whether the product is stored in the carton box placed at the corresponding storage position in step S21. At this time, when the corresponding storage indicator 28c is turned on in step S20, the controller 40 displays the picking trade name on the storage product indicator 28a installed corresponding to the storage indicator 28c.

For example, in the case of goods ordered from the first delivery address, the storage indicator 28c indicating the direction of the cartons CBX1 and CBX2 is turned on and instructed, and if it is determined that the goods ordered from the second delivery address are picked, the carton ( The storage indicator 28c indicating the direction of the CBX3 to 5 is turned on and is indicated. Thereafter, the output of the sensor unit 30 installed between the vertical frames 13 of FIG. 1 reads whether the picked product is stored in the cartons CBX1 and CBX2 positioned on the upper loading plate 17, and the lower loading plate 16. ) Is detected in the carton (CBX3 ~ 5) located in the) to determine whether it is correctly stored in the carton of the delivery.

For example, when there is an output from the sensor unit 30 within a predetermined time, the control unit 40 determines that the goods are stored in the direction of the lower loading plate 16, and vice versa, the upper loading plate 17 It is judged that the product was stored in the direction of). When the picked goods are stored differently from the storage instruction direction by the determination of the storage location as described above, the controller 40 notifies the picking worker that the storage is incorrect in step S22. That is, the monitor 20 indicates that the picking goods are stored incorrectly, and the voice output unit 38 is driven to guide the voice to prevent the picking storage error.

The picking operator who stores the picking goods in the cartons CBX1 to CBX5 loaded on the loading plates 16 and 17 selects the corresponding storage completion button 28b from among the storage completion buttons 28b installed corresponding to the storage location. When pressed, the lit storage indicator 28c goes out to restore the storage instruction.

In the embodiment of the present invention, the storage position of the picked goods is displayed to determine whether there is a storage error, but the controller 40 responds to the input of the storage completion signal according to the selection of the storage completion button 28b. The storage detection signal output from the unit 30 may be compared with the storage instruction signal, and according to the result, it may be operable to output a message indicating whether the storage of the picked goods.

In step S23, the controller 40 searches whether the picking information stored in the memory 36, that is, picking of the delivery address corresponding to the sorted shipment information, is completed in step S23. If the search result picking process of the step S23 is not completed, the control unit 40 can access the next product of the sort shipment information in step S24, and repeat the picking process from the above-described step S16.

If it is determined that the picking storage of the shipping address corresponding to the shipment information sorted in step S23 is completed, the control unit 40 displays the picking storage completion message for each shipping destination on the monitor 20 and voices in step S25. The output unit 38 is driven to notify the picking operator by voice to complete the picking operation.

As described above, the DPC 1 according to the embodiment of the present invention sets the carton in which the ordered goods are stored for each destination (the customer) corresponding to the destination, and then picks the corresponding goods to recognize the number of goods by the load cell. By indicating the position of the carton to be stored, the speed of picking can be increased, and the inspection process can be eliminated by accurate picking, so that the packing of the ordered goods can be made faster.
