DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figure 1The cargo sorting device shown comprises a mobile seat 1 and a driving mechanism 3 for driving the mobile seat 1 to move relative to a shelf 2; the shelf 2 is provided with grids arranged in an array, in which cargo boxes 7 can be placed; the mobile seat 1 is provided with a cargo box picking and placing mechanism 4, a sorting mechanism 5 and a accommodating box 6 which move with it; the driving mechanism 3 can move the mobile seat 1 to a position where the cargo box picking and placing mechanism 4 is aligned with any grid, so that the cargo box picking and placing mechanism 4 can take out any cargo box 7 on any shelf 2; the cargo box picking and placing mechanism 4 can take out the cargo box 7 from the shelf 2 and can put the cargo box 7 back on the shelf 2; the sorting mechanism 5 can transfer the cargo in the cargo box 7 to the accommodating box 6.

[0025] During operation, the driving mechanism 3 drives the movable seat 1 to move as needed so that the cargo box picking and placing mechanism 4 faces the target grid on the shelf 2, and then, the cargo box picking and placing mechanism 4 takes out the cargo box 7 from the target grid, and the sorting mechanism 5 transfers the target quantity of goods in the cargo box 7 to the accommodating box 6, and the cargo box picking and placing mechanism 4 puts the cargo box 7 back to the target grid.

[0026] In actual operation, picking can be done by order or by wave. Picking by order means that an order task is assigned to the cargo sorting device each time, and the cargo sorting device picks the goods in sequence according to the goods included in the order. After the order is completed, the driving mechanism 3 drives the mobile seat 1 to the release position, and the container box 6 is taken away and replaced with an empty container box 6, or only the goods in the container box 6 can be taken away. When picking by wave, multiple orders are combined into a wave task and assigned to the cargo sorting device. After the cargo sorting device completes the picking task of all the goods included in the wave task, the driving mechanism 3 drives the mobile seat 1 to the release position.

[0027] By adopting the cargo sorting device, it is possible to flexibly pick out the target quantity of cargo from the cargo box 7 in the shelf 2, without having to first take out the cargo box 7 and place it on the picking line and then return the cargo box 7 after the picking is completed. With fewer intermediate links, the sorting equipment and the required manpower can be effectively reduced, thus saving costs.

[0028] like Figure 2 As shown, the sorting mechanism 5 includes a multi-axis driving device 51 and a picking device 52 installed at the execution end of the multi-axis driving device 51. The multi-axis driving device 51 is a mechanical arm or a rectangular coordinate robot, and the figure shows a rectangular coordinate robot. The picking device 52 includes a suction cup and a gripper, which can meet the sorting needs of different types of goods.

[0029] like Figure 2As shown, the driving mechanism 3 includes two modules, namely a transverse translation module 31 and a longitudinal translation module 32, which can respectively enable the moving seat 1 to move transversely and longitudinally. And the module installed on the shelf 2 can be disassembled relative to the shelf 2. In this way, the cargo sorting device in the utility model can be conveniently integrated into the existing shelf, and the existing storage shelf can be upgraded and renovated to reduce the renovation cost.

[0030] In one embodiment, if Figure 4 As shown, the cargo box pick-up and placement mechanism 4 includes a telescopic fork 41 that can actively translate and a claw 42 installed at the end of the telescopic fork 41, and the claw 42 can rotate relative to the telescopic fork 41; and also includes a pusher that can translate with the telescopic fork 41. With this structure, when taking a box, the claw 42 is initially in a vertical state, the telescopic fork 41 is extended so that the claw 42 is placed on the back side of the cargo box 7, and then the claw 42 rotates to a horizontal state (such as Figure 5 As shown), the telescopic fork 41 is retracted to take out the cargo box 7. When returning the cargo box 7, the telescopic fork 41 is extended, the pushing member pushes the cargo box 7 back to the grid, the claw 42 is rotated to the vertical state, and the telescopic fork 41 is retracted.

[0031] In another embodiment, if Figure 3 As shown, the cargo box taking and placing mechanism 4 includes a suction cup mechanism 43 that can actively translate, and also includes a flat belt mechanism 44. With this structure, when taking a box, the suction cup mechanism 43 first sucks the cargo box 7 and pulls it back, so that a part of the cargo box 7 is in contact with the flat belt mechanism 44, and the flat belt mechanism 44 operates to assist the suction cup mechanism 43 in taking out the cargo box 7. When returning the cargo box 7, the flat belt mechanism 44 operates in the reverse direction and combines with the thrust of the suction cup mechanism 43 to return the cargo box 7 to the compartment.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
