Description

Technical Field

[0001] The utility model relates to the technical field of goods picking, in particular to an automatic relay picking system for small goods. Background Art

[0002] With the dramatic increase in the pharmaceutical industry's retail business volume and the diversification of retail channels, as well as the diversification of retail end customers, the demand for pharmaceutical logistics centers to ship out small-quantity medicines is increasing, and the workload of small-quantity picking operations is increasing. Therefore, how to improve the efficiency of small-quantity picking and the timeliness of outbound orders in pharmaceutical logistics centers requires the development of more reasonable optimization solutions.

[0003] The implementation scheme of the existing piece-rate picking mode is to use AGV automatic transport trolleys in conjunction with mobile piece-rate shelves, picking workstations, temporary storage shelves at picking workstations, replenishment conveyor lines, empty box supply conveyor lines, material box outbound conveyor lines, electronic tags, material boxes and order boxes and other equipment. The replenishment operator directly puts the replenishment medicines in full boxes or unpacked boxes at the replenishment station onto the mobile piece-rate shelf storage location transported by the AGV automatic transport trolley. After the replenishment is completed, the AGV automatic transport trolley transports the mobile piece-rate shelf to the corresponding storage location in the piece-rate area. During the piece-rate picking operation, the AGV automatically moves The transport cart transports the mobile small goods shelves with tasks to the picking work station. The temporary storage shelves at the picking work station are divided into three layers: upper, middle and lower. The staff takes the empty order boxes from the empty box supply conveyor line to the temporary storage shelves at the picking work station. The picking operators pick the goods into the empty order boxes according to the picking quantity displayed on the electronic tags on the temporary storage locations of the picking work station. After the task picking of the order box is completed, the operator pushes the order box to the material box outbound conveyor line and transports it to the review area for review and packaging. After the task picking is completed, the AGV automatic transport cart transports the mobile small goods shelves back to the corresponding location.

[0004] However, although the above-mentioned piecemeal picking operation mode can alleviate the picking pressure to a certain extent, the actual picking workstation operation area has multiple heights, and users may have to squat to work, which is very inconvenient to use. Secondly, the continuity is poor and the relay picking function cannot be realized. Utility Model Content

[0037] How it works

[0038] Example 1

[0039] The following steps are included:

[0040] S1. When a pick-up task for small items occurs, the relay box 7 is placed on the top of the second multi-grooved belt in the relay picking conveyor line 5, the second motor in the relay picking conveyor line 5 is activated, and the second multi-grooved belt is coordinated with the corresponding second roller to drive the relay box 7 to automatically move. The relay picking conveyor line 5 conveys the relay box 7 to the position where the temporary storage shelf 6 and the lifting platform 11 are aligned, and the relay picking conveyor line 5 is closed. Then, the brake stepper motor 121 is started, and the output end of the brake stepper motor 121 drives the pressure rod 122 to rotate and press the relay box 7, so that the relay box 7 is automatically moved from the relay picking conveyor line 5 to the top surface of the lifting platform 11, and the gear plate can limit the relay box 7.

[0041] S2. After the relay box 7 moves to the top of the lifting platform 11, the electric push rod 10 is turned on. The output end of the electric push rod 10 drives the lifting platform 11 and the relay box 7 on the top of the lifting platform 11 to be aligned with the side of the relay picking conveyor line 5 in the middle of the picking temporary storage shelf 6, thereby facilitating the operator to pick the goods;

[0042] S3. The inventory management system sends the corresponding order relay picking task to the relay box 7 where the goods are to be picked, and issues a picking instruction to the AGV automatic transport vehicle 1. After receiving the picking instruction, the AGV automatic transport vehicle 1 moves to the bottom of the small goods shelf 2 where the goods are located, and then uses its own lifting mechanism to lift the small goods shelf 2, and then transports the small goods shelf 2 to the corresponding workstation of the corresponding picking temporary storage shelf 6 along the route calculated in advance by the system;

[0043] S4. The operator checks the computer and requests a relay task order in the inventory management system. The task order contains the shelf location number of the small goods to be relay-picked and the quantity of goods to be picked. The operator picks the corresponding small goods from the shelf location 2 of the small goods shelf according to the shelf location number and quantity in the requested task order.

[0044] S5. During the picking process, the electronic tag 9 corresponding to the relay box 7 on the temporary storage shelf 6 lights up. The electronic tag 9 displays the quantity of goods to be put in. The operator checks and puts the goods in place according to the quantity displayed on the electronic tag 9. After the goods are put in place, the electronic tag 9 of the location is turned off for confirmation.

[0045] S6. When the goods in the relay box 7 are picked, the background computer displays that the operation of the relay box 7 is completed. Then, the operator pushes the relay box 7 to the top of the first multi-groove belt in the corresponding material box outbound conveyor line 4, activates the first motor in the material box outbound conveyor line 4, and cooperates with the corresponding first roller to make the first multi-groove belt drive the relay box 7 to automatically move out of the warehouse, and the picking operation of the scattered goods is completed.

[0046] Example 2

[0047] S1. For the relay picking task of small items, the steps of the above-mentioned embodiment 1 are followed. When the basic material box 8 on the shelf 2 of small items is picked and emptied, the basic material box 8 is placed on top of the third multi-grooved belt in the empty material box supply conveyor line 3. The third motor in the empty material box supply conveyor line 3 is activated, and the third motor cooperates with the corresponding third roller to cause the third multi-grooved belt to automatically move the empty basic material box 8.

[0048] S2. After reaching the designated location, the small goods operator clicks on the basic material box 8 cargo position association in the computer inventory management system, then picks up the empty basic material box 8 on the empty material box supply conveyor line 3, and scans the second barcode label on the basic material box 8 to associate the cargo position, which is convenient for subsequent staff to replenish. At this point, the supply operation of the empty basic material box 8 is completed.
