[0027] Working principle:

[0028] The automatic sorting equipment for spandex production of the present invention is composed of a plurality of cooperative components, which can realize automatic flipping, precise positioning and continuous sorting of the bobbin from the reversed state to the normal state; during the sorting process, the wire-taking robot first places the bobbin 17 in the reversed state in the clamping claw cylinder 2 of the flipping mechanism, which is installed on the rectangular section 22 of the flipping shaft 16 and fixed by screws to ensure the stability of the clamping process; the flipping is driven by a servo motor 15 installed on the side of the flipping frame 14, which drives the flipping shaft 16 to rotate through the coupling 19; after the flipping is completed, the bobbin 17 is released and falls into the positioner 20 with a chamfered structure below, which is a circular recessed seat structure and is fixed to the positioning plate 10 by screws through the fixing hole 21 to realize the precise reception of the bobbin.

[0029] The overall turning mechanism is fixed on the slide rail 8 through the slider 9, forming a sliding connection with the single-row frame 1. The three-axis cylinder 7 is installed on the right side of the frame, and its output shaft pushes the turning frame 14 to move on the slide rail, realizing the forward and backward movement of the turning device; the bobbin after positioning is conveyed by the chain 13 arranged on the single-row frame 1. This chain is connected by the driving sprocket 12 and the driven gear 18 to form a closed loop. The servo motor 1 5 drives the driving shaft 3 through the reducer 6 to drive the chain to move, transporting the positioning plate carrying the bobbin to the parallel robot work position; to ensure the stability of the chain operation, guide bars 11 are also provided in the frame for guiding and supporting; the whole set of equipment is closely coordinated and reasonably structured, and can continuously and efficiently complete the turning, positioning and conveying of the bobbin, meeting the automatic sorting requirements of spandex products with multiple spindle positions and multiple specifications.
