technical field

The invention relates to the technical field of automated clothing production lines, in particular to an internal circulation screening station and a control method thereof.

Background technique

The garment hanging system includes a main rail and workstations distributed around the main rail. The pieces are conveyed by the main rail and pass through the corresponding workstations in turn to complete the sewing of the required clothes.

For this reason, in the prior art, a screening station is set up in front of the workstation, and the pieces of other colors and sizes that originally need to enter the corresponding workstation are screened out through the screening station, so that the workstation can only process specific pieces of the same color and the same size within a certain period of time. Cut pieces, thereby improving the work efficiency of the workstation. In the existing screening station, as shown in Figure 1, the carrier passes from the main rail to the reading sensor in front of the screening station. If the piece on the carrier is the piece currently being processed by workstation 3, then the carrier is on the main rail. Go ahead and enter Workstation 3; if the piece on the carrier is not the piece currently being processed by Workstation 3, then the action of the screening station will introduce the corresponding carrier to the screening station, and the carrier will return to the main rail after passing through the screening station. Before deciphering the sensor, the vehicle passes the deciphering sensor again and repeats the above screening steps.
