Automatic turn-over device for long-roll sock legs and control method

Abstract

The invention discloses an automatic turn-over device for long-roll sock legs and a control method. The automatic turn-over device comprises a sock tube fixed to a rack, and further comprises a feeding compression mechanism, a chain driving mechanism, a lifting air suction mechanism, a material collecting winding roller mechanism, a mechanical arm mechanism, a sock head clamping mechanism, a detection sensor set, an automatic binding machine and a control cabinet. According to the automatic turn-over device, in the feeding process, the return speed of the feeding compression mechanism and therunning speed of a conveying belt are controlled according to the load torque change of a servo motor, the quality of sock materials is guaranteed, and meanwhile the long-roll sock legs with differentthicknesses and different lengths can be stacked on the sock tube; and in the material turning process, automatic identification and automatic binding of sock heads and sock tails are achieved in combination with detection of the detection sensor set and cooperative action of the lifting air suction mechanism, the material collecting winding roller mechanism, the sock head clamping mechanism andthe automatic binding machine. According to the automatic turn-over device, the processes of automatic feeding, automatic overturning, automatic head and tail recognition and bundling and precise conveying of a mechanical arm after manual sock sleeving can be achieved, the labor intensity is reduced, the sock product quality is effectively guaranteed, and the reliability and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to an automatic turning-over device and control method for a long-rolled stocking tube. Background technique [0002] In the textile industry, turning over the cylindrical fabric is a necessary process in the production process, the purpose is to ensure the treatment of the inner surface of the fabric. Before the napping and dyeing process of the long stocking tubes, it is necessary to turn over the stocking tubes with a length of more than 100 meters, and connect the heads and tails of dozens of long stocking tubes after turning over to form a whole, which is convenient for subsequent production and processing. At present, most textile enterprises use artificial sleeves for turning over and connecting, which is very labor-intensive and seriously affects production efficiency. [0003] The invention patent with the application number of 201510126746.1 discloses "an automa...
