[0030] In the embodiment, the plurality of grippers 34 are arranged on the first telescopic driver 33, and the first telescopic driver 33 is connected with the rotating driver 31. In operation, when the picking mechanism 3 is moved to the top of the target fabric piece by the moving mechanism 2 so that the grippers 34 are opposite to the center point of the fabric piece, the rotating driver 31 can be started to drive the first telescopic driver 33 and the grippers 34 to rotate together, so that the projections of the plurality of grippers 34 fall on the physical positions of the fabric piece, avoiding falling in the empty positions, and then the first telescopic driver 33 drives the grippers 34 to move to the fabric piece until the fabric piece is contacted to pick the fabric piece. Then, the first telescopic driver 33 is reset to lift the grippers 34. Then, the moving mechanism 2 is actuated again to move the grippers 34 to the corresponding material placement position. In this way, the sorting work of each fabric piece is completed through the cyclic operation.

[0031] Therefore, the sorting device can make the grippers 34 realize the precise rotation and linear telescopic movement in the two perpendicular planes through the linkage of the rotating driver 31 and the first telescopic driver 33, ensure that each fabric piece is accurately picked and placed, avoid the empty picking of the grippers 34, and make the sorting device applicable to the fabric pieces with various chaotic postures, thereby improving the flexibility of the operation of the sorting device.

In this embodiment, when the gripper 34 grabs the fabric piece, the pressing rod 38 is pressed on the cloth area outside the fabric piece and adhered to the fabric piece, so as to separate the fabric piece from other fabrics by lifting the gripper 34.

[0038] On the other hand, as Figure 1 The moving mechanism 2 comprises a first track 20 arranged above the sorting platform 1 and a second track 21 arranged on both sides of the sorting platform 1, the extension directions of the first track 20 and the second track 21 are perpendicular to each other, the first track 20 and the second track 21 are slidingly connected, and the mounting bracket 30 is slidingly connected with the first track 20.
