As shown in Figure 2, the specific picking method of the picking device of the present invention is as follows: first use the supporting code scanning gun to scan the batch number, and then the controller will immediately obtain the batch number and query the batch number through the api interface of the wms system through the Internet. All order details (including order quantity, name, etc.) are displayed at the feeding port screen 7; then the current batch of goods to be sorted is manually placed in the temporary storage box in units of sku, and Scan the barcode of the feeding port corresponding to the temporary storage box and the barcode on the goods in the temporary storage box in sequence - the corresponding relationship between the goods and the feeding port corresponding to the temporary storage box will be established inside the controller, and then the first turnover basket will be manually Placed at the starting position of the upper layer of the transportation line (that is, the starting position of the horizontal chain plate), the distance between the limit blocks set on the horizontal chain plate 10 is exactly the width of a turnover basket, that is, the distance between the limit blocks is exactly Putting down a turnover basket, the turnover basket must be manually placed between the limit blocks, and then the assembly line is started. At this time, the turnover basket sensor at the starting position (next to the horizontal chain plate) will sense that the turnover basket has been placed at the starting position Yes, after the controller receives the signal from the turnover basket sensor, it will command the servo motor to start rotating, so the horizontal chain plate 10 drives the first turnover basket forward, and at the same time, the position sensor under the horizontal chain plate 10 will be triggered by the passing limit block ——The controller will stop the servo motor after receiving the signal from the position sensor, and the horizontal chain plate 10 will also stop accordingly. At this time, the distance (step length) traveled by the horizontal chain plate 10 is just the width of a turnover basket. A turnover basket just aligns with the belts of the two oblique feeding ports that are symmetrically arranged (the belts of the two feeding ports 11 are just aligned with the turnover basket), and then the internal system of the controller will calculate whether it is necessary to feed to the turnover basket, and in It is displayed on the screen 7 of the feeding port. If feeding is required, the roller motors of the two oblique feeding port belts arranged symmetrically will be started, and the feeding port belt will start to rotate, and the goods in the temporary storage box corresponding to the feeding port 11 will be placed manually. On the feeding port belt 8, driven by the drum motor, the feeding port belt is continuously and automatically fed into the turnover basket (each turnover basket represents an order, and the worker only needs to put the goods on the slope feeding port belt. Workers don't need to care about how much to put in. The belt at the feeding port turns, and the goods will fall into the turnover basket. The workers only need to replenish the goods on the belt at the feeding port. When the quantity is enough, the belt will stop and the workers will stop. Just put the goods); after the goods fall into the turnover basket, a count is completed, and the control system will stop the feeding port 11 from feeding into the turnover basket until the quantity of the dropped goods meets the requirements. Then manually place the second turnover basket at the starting position of the assembly line, and the horizontal chain plate 10 moves forward one step further (the step length is the width of the turnover basket). At this time, the first turnover basket advances to correspond to the front feeding port. The second turnover basket corresponds to the feeding port at the initial position. The control system calculates again whether the feeding port needs to be fed to the turnover basket. If necessary, start the corresponding feeding port. The third turnover basket is placed at the starting position of the assembly line, and the horizontal chain plate 10 moves forward again, repeating the feeding process, going round and round until all sorting tasks are completed. After manually packing the goods in the turnover basket, the empty turnover basket will be placed on the lower horizontal belt conveyor 2, and the horizontal belt conveyor 2 will drive the empty turnover basket back to the starting position of the assembly line for reuse.
