Description

Technical Field

[0001] The present invention belongs to the technical field of industrial automated warehousing, and in particular relates to an integrated storage container for synchronous and rapid sorting of multiple material boxes. Background Art

[0002] At present, in the field of industrial automated warehousing equipment, cargo storage carriers are mainly in the form of pallets and boxes. Rail-mounted aisle stackers, multi-layer shuttle vehicles, AGV forklifts, powered racks, etc. are used for entry and exit of warehouses to realize automatic entry and exit of single pallets or single boxes.

[0003] In the automated warehousing industry where bins are used as carriers, except for the box-type storage AGV, which can store and retrieve multiple bins in a single cycle, the other types can only store and retrieve one independent bin in a single cycle. Taking the most advanced multi-layer box-type storage AGV (mainly six-bin specifications) as an example, the AGV patrols the fixed bin shelf area, extracts the target bin, and then transfers it to the AGV's own temporary storage platform for bins, and continues to look for the next bin for repeated extraction until the temporary storage platform is full or the target bin is extracted. The AGV quickly swims to the picking station outside the rack storage area, and then takes the bins off the AGV's temporary storage platform one by one and transfers them to the picking platform. In this mode, the AGV needs to patrol the entire shelf area, and each bin needs to be transferred to and taken off the temporary storage platform when entering and leaving the warehouse, which consumes a lot of man-hours. The single entry or exit time is more than five minutes (it can reach more than 10 minutes when the warehouse area is large), and more AGVs are needed to speed up the beat.

[0004] The storage management characteristics of the automated storage application with material boxes as carriers are that the materials are of many varieties, small size, light weight, high frequency of storage and retrieval, fast picking speed, and mostly whole storage and partial retrieval. This poses a great challenge to the efficiency of material box entry and exit of material box automatic storage equipment. There are two main directions that need to be solved essentially: 1. Efficient frequency and efficiency of material box entry and exit; 2. The average efficiency of material box entry and exit must be higher than the picking efficiency of operators. Only in this way can we truly achieve the operating effect of "goods waiting for people" instead of "people waiting for goods".

[0005] At present, the automated material box storage industry is all about fast single-box storage and warehousing. After each picking is completed, it is necessary to wait for the system to return the current material box to the warehouse, and then send the next material box to the picking port. The single-box storage and warehousing mode has become the biggest bottleneck of equipment efficiency; "people waiting for goods" has become the norm in the industry. The low operating efficiency of multi-layer box storage AGVs also cannot change the reality of "people waiting for goods". Increasing the number of AGVs to increase the beat also requires solving the path conflict waiting problem between AGVs.

[0006] Therefore, the industry is in urgent need of an automated warehousing system that can not only quickly enter and exit the cargo boxes, but also retrieve multiple boxes at a time, to truly realize "goods waiting for people". Only in this way can we meet the challenge of the efficient production rhythm of current advanced automated production equipment to the efficiency of automated warehousing, distribution and picking, break through the efficiency bottleneck between production-logistics-storage and warehousing, and achieve effective cost reduction and efficiency improvement for the enterprise.

[0038] As a technical optimization solution of the present invention, the setting of the operating terminal 21 makes it easier for the staff to control the device.

[0039] The working principle and use process of the present invention: When using the device, the fork lifting platform 702 in the material box extraction mechanism assembly 7 in the center of the equipment drives the lifting gear 701 to rotate on the lifting rack 6 through the lifting motor 703, thereby realizing the rapid vertical lifting movement of the material box extraction mechanism assembly 7, and the five groups of fork assemblies 705 on the fork lifting platform 702 are driven by their own independent horizontal motors 704 to rotate the gears and translate the racks, thereby realizing the rapid horizontal movement of the fork assemblies 705;

[0040] According to the order list of inbound and outbound tasks, the system automatically optimizes and decomposes the tasks based on the inbound and in-stock data to ensure that the target material boxes for each task are distributed at different fork positions, forming the actual storage and retrieval echelon tasks;

[0041] That is, the system, according to this access task, raises the fork lift platform 702 to the target material box at the highest position in the task, controls the corresponding position fork assembly 705 to extend (according to the actual situation, it can be one group of fork assemblies 705, or multiple fork assemblies 705 forks are extended at the same time), and then the fork lift platform 702 rises 20mm, so that the fork assembly 705 lifts the material box and detaches from the material box layer 3, and the fork assembly 705 retracts to pull the material box onto the fork lift platform 702, and the fork lift platform 702 descends to the height of the next material box and repeats the action of the fork assembly 705 taking the material box, until five target material boxes are obtained and then directly descended to the operation port, and the five material boxes are sent to the operation table 14 together by five groups of forks for the operator to pick;

[0042] After picking is completed, the five groups of fork assemblies 705 will lift all the items on the operating table 14 back to the fork lifting platform 702. Through the system optimization algorithm, scheduling is carried out based on the principle of the shortest path. The warehousing of the material box and the next material box out of the warehouse will form a mixed action, that is, the warehousing of the material box and the next material box out of the warehouse will be carried out at the same height at the same time. After completing the warehousing tasks of five material boxes, the next group of five material boxes will be out of the warehouse and extracted synchronously and sent to the operating table 14. This cycle mode is continued until all warehousing and out-of-warehouse tasks are completed.

[0043] The characteristics of the device are as follows: the overall equipment occupies an area of ​​2945mm in length, 2310mm in width, and 12000mm in height, and a total of 345 material boxes with a length of 600mm, a width of 400mm, and a height of 280mm can be stored. The equipment supports order-based batch warehousing and out-of-warehouse tasks. The equipment can deliver 5 material boxes of different materials at a time, with an average time consumption of ≤40s / time, and an average warehousing and out-of-warehouse efficiency of ≤8s / box, which is much higher than the efficiency of personnel picking. The actual efficiency measured at the actual operation site can reach a maximum warehousing and out-of-warehouse frequency of 420 boxes / hour. The equipment of the present invention can realize functions such as closed storage of materials, dust and anti-static protection, temperature and humidity management, and overheight and overweight detection of goods. It is very suitable for the automatic storage application scenario of material boxes with multiple varieties and high frequency of warehousing and out-of-warehouse. (Characteristics of the material box extraction mechanism component 7: lifting speed 0~1.2m / s, accuracy ≤1mm, adjustable speed; horizontal speed 0~0.8m / s, adjustable speed; 5 material boxes can be operated simultaneously at a time, and the number of single material boxes can be customized as needed)

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
