Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The goods-to-person warehousing and sorting system shown in fig. 1 comprises a warehousing area a, a sorting workstation B, a carrier C and an racking workstation D.

The storage area A is used for storing the movable goods shelf 1, and the goods containers and goods which can be taken out are loaded on the movable goods shelf 1. The goods container is used for storing goods, the goods container can be a special plastic material box or a packaging paper box which is carried by the goods when the goods leave a factory, and the plastic material box or the packaging paper box contains a specific number of goods. For large goods, the large goods can be independently and directly put on the shelf in the movable goods shelf 1.

As shown in fig. 2, the sorting station B has a first docking station 2, a pick-up robot 3 and a sorting table 4; the goods taking robot 3 can take out and put back goods containers and goods from the mobile shelf 1 placed at the first docking station 2. As shown in fig. 4, the pickup robot 3 includes a frame body 33, the pickup unit 31 and a biaxial cartesian robot 32 for driving the pickup unit 31 to move in a vertical plane are installed in the frame body 33, the biaxial cartesian robot 32 drives the pickup unit 31 to move so that the pickup unit 31 faces a target cargo space, and the pickup unit 31 performs an operation of picking up or putting in a cargo. In this embodiment, two sets of pickup units 31 and two sets of biaxial cartesian robots 32 are provided in the frame body 33. In other embodiments, the picking robot 3 may also be an industrial robot with a gripper.

As shown in fig. 5, the racking station D includes a second docking station 6, a racking robot 7, and a racking platform 8; the racking robot 7 is used for loading the movable rack 1 parked at the second parking position 6. The structure of the racking robot 7 is the same as that of the goods-taking robot 3, and the detailed description is omitted here.

The carrier C can carry the mobile rack 1 between the storage area a and the first parking space 2, and can also carry the mobile rack 1 between the storage area a and the second parking space 6. In this embodiment, the transport vehicle C is a latent transport AGV.

Specifically, as shown in fig. 3, the sorting table 4 has two endless sorting lines, each of which has a first input location 41, a sorting location 42 and a return location 43; the first input position 41 and the return position 43 are positioned at the head end and the tail end of the annular sorting line, and the first input position and the return position are adjacent; two annular letter sorting circuit symmetry overall arrangement, and two on the two letter sorting position 42 are located both sides of both symmetry midlines, and two letter sorting position 42 adjacent settings.

Through above-mentioned overall arrangement, because two letter sorting positions 42 are adjacent to each other and set up, a manual work or sorting robot can sort the goods on two annular letter sorting circuits in turn, so usable goods container leaves letter sorting position 42 and next goods or goods container have not reached the latency between the letter sorting position 42 and sorts the goods of letter sorting platform 4 department on another annular letter sorting circuit, improve letter sorting efficiency. In addition, the first input position 41 is adjacent to the return position 43, so that the goods can be conveniently taken away and put back by the goods taking robot 3.

Preferably, the sorting table 4 has a kick-out position 44, and the two circular sorting circuits share the same kick-out position 44. The kick-out position 44 is used for kicking out the abnormal bin and the empty bin to the outside of the annular sorting line.

Specifically, the sorting table 4 comprises a first wire body L1, and a second wire body L2 and a third wire body L3 arranged in parallel with the first wire body L1; the second line body L2 and the third line body L3 are arranged in a collinear manner and are respectively positioned at two sides of a symmetrical middle line of the first line body L1; transfer mechanisms are arranged between the two ends of the second wire body L2 and the two ends of the third wire body L3 and the first wire body L1, and the transfer mechanisms adopt the prior art, such as the prior wire changing mechanisms such as an air cylinder push-pull mechanism and the like; the kick-out position 44 is located at one end of the first line L1. The first input position 41 and the return position 43 are located on the first wire body L1, and the return position 43 is close to the symmetrical middle line of the first wire body L1. The two sorting positions 42 on the two annular sorting lines are respectively positioned on the second line body L2 and the third line body L3, and the two sorting positions 42 are respectively provided with a transfer mechanism. The two parts of the first wire body L1 on two sides of the symmetrical middle line can independently run.

During sorting, the goods or goods containers obtained by the goods taking robot 3 are placed on the first input position 41, the first line body L1 operates to convey the goods or goods containers to the position of the transfer mechanism, the transfer mechanism pushes the goods or goods containers to the second line body L2 from the first line body L1, the second line body L2 conveys the goods or goods containers to the sorting position 42, after manual or sorting of the sorting robot is completed, the transfer mechanism transfers the remaining goods to the return position 43 on the first line body L1, and the goods taking robot 3 takes the remaining goods away from the return position.

Preferably, a first buffer storage rack 5 is erected above the sorting table 4. The first cache shelf 5 is used for placing hot goods, and because the hot goods are transferred frequently, the hot goods are placed on the first cache shelf 5, when the hot goods need to be picked, the goods or goods containers can be directly obtained from the first cache shelf 5 by the goods-taking robot 3 and conveyed to the first input position 41, and after sorting is completed, the remaining goods are taken away from the return position 43 and the remaining goods are placed back to the first cache shelf 5. When the cargo container is empty or there is an abnormality in the cargo container, the cargo container is moved onto the first line body L1, and the first line body L1 is operated to transfer the container in question to the kick-out position 44.

Further, as shown in fig. 6, the upper supporting table 8 has a main wire body 81, the main wire body 81 sequentially has an upper supporting operation position 82, a removing position 84 and a second connection position 83, the second connection position 83 is disposed at a side of the main wire body 81, and a transfer mechanism is disposed on the main wire body 81 at a position corresponding to the second connection position 83; the racking robot 7 and the second docking position 6 are arranged beside the second docking position 83, and the racking robot 7 acquires goods or goods containers from the second docking position 83 and racks the goods or goods containers onto the racks at the second docking position 6.

The removing position 84 is connected with a branch line body 85, and a transfer mechanism is arranged at the removing position 84. When the main line body 81 transports a cargo or a cargo container, if the cargo or the cargo container is abnormal, the transfer mechanism at the rejecting position 84 transfers the cargo or the cargo container to the branch line body 85.

Preferably, a second buffer rack 9 is arranged above the second connecting position 83. The racking robot 7 may store the hot goods on the second cache shelf 9, or the racking robot 7 may store the goods on the second cache shelf 9 first when the shelf corresponding to the goods has not arrived yet.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
