When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

As shown in fig. 2, 4 to 8, the present disclosure provides a goods picking device for a shelf, the goods picking device comprising a mounting frame 11 disposed at one side of the shelf 10, a goods picking rod 12 connected to the mounting frame 11, and a grabbing member 13 mounted on the goods picking rod 12, wherein one end of the goods picking rod 12 where the grabbing member 13 is mounted can move axially relative to the goods picking rod 12, where "axial movement" refers to movement of the goods picking rod 12 in its own axial direction, and may include an embodiment of axial movement of the whole rod described below, and also includes an embodiment designed as a telescopic rod, so that the grabbing member 13 can enter and exit the shelf 10, and the goods picking rod 12 may also be connected to the mounting frame 11 in a circumferential rotation manner to transfer goods 101 between the shelf 10 and a predetermined position. Here, it should be noted that the "picking" includes a loading process of placing the goods at the predetermined position on the shelf 10 and a removal process of removing the goods on the shelf 10 to the predetermined position. The mounting frame 11 may be any suitable structure, and is mainly used for carrying the picking rod 12, the picking rod 12 is disposed at one side of the shelf 10, and the position of the mounting frame 11 relative to the shelf 10 can be adjusted, so that the picking rod 12 can freely move axially and rotate circumferentially in the space between the shelf 10 and the mounting frame 11 without interfering with the shelf 10. The grabbing part 13 may be a mechanical arm capable of grabbing the goods 101, or may be a suction cup type structure that grabs the goods by vacuum adsorption, which is introduced below, and the structure capable of realizing the actions of grabbing and placing the goods 101 all belong to the protection scope of the present disclosure. The reservation location may be any suitable location, such as a location near the access opening, or a loading location for centrally storing goods.

Through above-mentioned technical scheme, in the sorting device that this disclosure provided, but pick goods pole 12 axial motion and circumferential direction, both cooperate, can convenient and fast ground accomplish the letter sorting of goods, arrange the goods neatly on goods shelves 10, or transport goods to the assigned position with goods shelves 10, realize the automatic sorting function, in addition, should pick goods device applicable in the ordinary goods shelves of arbitrary structure, can directly reform transform on ordinary goods shelves, fall with low costsly, fast, have good compatibility and can fall to the ground the nature.

The pick rod 12 may be axially movable and circumferentially rotatable in a variety of ways. As an exemplary embodiment of the present disclosure, as shown in fig. 4, the order picking rod 12 is connected to the mounting frame 11 through a connection block 14, the order picking rod 12 is axially movably connected to the connection block 14, and the connection block 14 is rotatably connected to the mounting frame 11.
