Specific examples:

the M warehouse is a delivery warehouse in the production of a certain automobile logistics company, wherein the X sorting area is positioned on a second floor steel platform of the M warehouse, and the usable height of the second floor is only 3.5M. The material box is placed on the three-layer fluent goods shelf in the original mode, and the material box is often stacked in disorder and is disordered in layout when the material is put into goods due to limited logistics area. The X picking area adopts a 'person to goods' picking mode, and zero disassembly picking is carried out on the parts according to the parts. As the last link before the parts are on line, the link has very strict requirements on the picking accuracy and time, 6 picking orders are required to be completed in 5 minutes, and the picking accuracy is 100%. However, the 'people to goods' order picking operation needs to walk back and forth, and the manual judgment has the problems of low picking efficiency, high risk of missed preparation, high labor intensity, high labor cost and the like.

The X sorting area has 87 kinds of parts, including 35 kinds of high-frequency parts and 52 kinds of low-frequency parts. The packaging size of the appliance is 600mm x 400mm or less. The number of parts used per hour is 1301.28. The hour flow rate was 68.31 boxes/hour, and the 4 hour inventory was 275 boxes, so the storage cargo space demand was 275.

According to the available height of the second-floor sorting area of the M warehouse, which is 3.5M, the number of layers of the three-dimensional warehouse is designed to be 5. The size of the X picking area is 600mm or less than 400mm, so that the length and width of the designed shuttle car picking three-dimensional warehouse shelf are 600mm and 400mm respectively, and each 5 shelves of single layer are a group.

To meet the 4 hour inventory requirement of X pick zone parts, 8 sets of racks are now designed, with four sets of racks on the storage side and 4 sets of racks on the pick side. A total of 280 storage bits, 75 picking bits. Because the high-frequency part picking positions are subjected to positioning treatment, the number of the first picking positions is 35; the low-frequency parts are subjected to warehouse-out and warehouse-back operation according to the requirements, so that the low-frequency picking position depends on the SKU maximum value of the single-wave low-frequency parts to be subjected to warehouse-out. The statistics are carried out to obtain: the maximum SKU value of the single-wave low-frequency parts to be delivered is 25, so that the number of second picking positions is 25. The rest goods shelves are used as emergency picking goods shelves, and the number of emergency picking positions is 15.

The original picking area occupies about 78.94m < 2 >, the existing picking area occupies 50.4m < 2 >, the area is optimized by 36%, the space utilization is maximized, the space utilization is improved to 93.5%, and the problems of disordered layout and arrangement of a warehouse, difficult field 5S management and the like are solved.

Taking 5 minutes as one wave as a picking order cluster, dividing one hour into 12 waves, wherein the work load per hour of the picking shuttle depends on the frequency of part warehouse-in, warehouse-out and warehouse-back, the part warehouse-in flow is 68.31 boxes/hour, the high-frequency part warehouse-out flow is 38.9 boxes/hour, and the frequency of single wave low-frequency part warehouse-out and warehouse-back is 100 times/hour

The single box out/in/out warehouse time for completion of the picking shuttle was 33s, and the total time taken to calculate the one hour workload completion of the shuttle was about 49.5 minutes. This indicates that under the precondition that each SKU of the low frequency part switches the maximum SKU task number (worst case), the total operation of one hour (12 wave) takes 2968.75S/49.5min, which satisfies the picking aging requirement of completing 6 picking orders in 5 minutes.

In summary, by establishing the storage and separation integrated shuttle picking equipment, the upper space is utilized to the maximum, the space utilization rate is improved, the occupied area of a picking area is reduced, and the problems of insufficient field logistics area, disordered layout and the like are solved; meanwhile, the 'goods arrive at person' picking improves the picking efficiency, reduces the risk of missed preparation and reduces the labor intensity and the labor cost.

While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
