Specifically, when the carrying trolley 6 does not receive a conveying instruction, the carrying trolley 6 is positioned on the horizontal running track 3, and at this time, the carrying trolley 6 can supply power to the super capacitor by means of the horizontal power taking mechanism 6-15. When the control mechanism sends a conveying instruction and the carrying trolley 6 receives the conveying instruction, the carrying trolley 6 starts to drive the driving connecting shaft to rotate at the driver so as to drive the driving wheel set to synchronously rotate; after the carrying trolley 6 reaches the position of the material box 7 to be conveyed, the driving sprocket 6-2 drives the driven sprocket to rotate, the conveying chain 6-1 carries out circular motion to drive the first conveying rod 6-7 and the second conveying rod 6-8 to move to the designated positions, the driving sprocket 6-2 drives the conveying chain 6-1 again to drive the first conveying rod 6-7 and the second conveying rod 6-8 to be sequentially connected with the corresponding clamping grooves at the bottom of the material box 7, and therefore when the material box 7 is at the designated position (on the conveying platform) of the carrying trolley 6, the driving sprocket 6-2 stops rotating.

specifically, the control mechanism receives warehouse-out and/or warehouse-in information of the material boxes, generates warehouse-out and/or warehouse-in instructions according to the warehouse-out and/or warehouse-in information of the material boxes, and returns the warehouse-out and/or warehouse-in instructions to the carrying trolleys, wherein one carrying trolley may receive the warehouse-in instruction and the next warehouse-out instruction which is queued at the same time, or different carrying trolleys may receive the corresponding warehouse-in instruction and the corresponding warehouse-out instruction respectively.

Step S102, a control mechanism starts a carrying trolley to move to a position of a goods shelf unit corresponding to the warehouse-out information according to the warehouse-out information, and transfers material boxes on the goods shelf unit to be conveyed to a sorting station section; and/or the control mechanism starts the carrying trolley to move to the position of the goods shelf unit corresponding to the warehousing information according to the warehousing information, and puts the material box on the carrying trolley into the goods shelf unit.

Specifically, the control mechanism sends out a current warehouse-out instruction to the no-load carrying trolley on the ground running track; controlling the no-load carrying trolley to travel to a sorting area; according to the no-load information obtained by the control mechanism, the control mechanism controls the turnover mechanism not to act; the no-load carrying trolley runs to a warehouse-out target goods shelf along the running track and conveys the material boxes on the warehouse-out target goods shelf to the sorting area; the control mechanism controls the turnover mechanism to turn over the carrying trolley and the material box according to the obtained carrying information, unloads the objects in the material box, and simultaneously places the objects in the sorting area in the material box; and the control mechanism controls the turnover mechanism to reset the carrying trolley and the material box according to the obtained carrying information to finish the warehousing instruction.

It should be noted that, before the control mechanism starts the transportation cart according to the warehousing information, the control mechanism searches for the current ex-warehouse information of another transportation cart, and sets the start-up transportation cart to operate to the shelf unit corresponding to the ex-warehouse information according to the ex-warehouse information. Therefore, on the premise that another carrying trolley is not used for completing the warehouse-out task, the current carrying trolley directly performs the warehouse-out task after the current warehouse-in command is executed; not only reduces the operation cost and maintenance, but also improves the efficiency of sorting objects.

Similarly, the control mechanism starts the carrying trolley to move to the position of the goods shelf unit corresponding to the warehouse-out information according to the warehouse-out information, takes the material box on the goods shelf unit and conveys the material box to the sorting station section,

before the carrying trolley is started according to the warehouse-out information, warehouse-in information of another carrying trolley is searched currently, and the carrying trolley is started to run to the goods shelf unit corresponding to the warehouse-in information according to the warehouse-in information. Therefore, on the premise that another carrying trolley is not used for completing the warehousing task, the current carrying trolley directly performs the warehousing task after the current ex-warehouse command is executed; not only reduces the operation cost and maintenance, but also improves the efficiency of sorting objects.

It should be noted that at least one empty shelf unit is reserved in each column and/or each row. Therefore, the carrying trolley can store the current material boxes on the goods shelf, and the material boxes discharged from the warehouse can be executed in the same row and/or row, namely, the sorting efficiency is improved by using the storage space.

The material sorting method can be used for sorting materials rapidly and reasonably by using a small amount of carrying trolleys, so that the sorting efficiency of the materials is greatly improved, the utilization rate of the storage space is also improved, and the operation cost of enterprises is reduced.

Although the present application has been described with reference to the preferred embodiments, it is not intended to limit the present application, and those skilled in the art can make variations and modifications without departing from the spirit and scope of the present application, therefore, the scope of the present application should be determined by the claims that follow.
