Abstract

The invention provides aligning control system and method for end surfaces of double-layer fabrics of a sewing machine, and belongs to the technical field of the sewing machines. The aligning control system for the end surfaces of the double-layer fabrics of the sewing machine is characterized in that the sewing machine comprises a machine head, a sewing stand, two feeding mechanisms, a fabrics sensor and a microcontroller, wherein the fabrics sensing device is used for recognizing whether fabrics are conveyed to a pressing pin as well as recognizing the number of the layers of the fabrics conveyed to the pressing pin; the microcontroller is respectively connected with a signal output end of an infrared emitter or an infrared laser emitter and an infrared receiver, the control end of the pressing pin, and the control ends of the two feeding mechanisms; the microcontroller is used for comparing the received voltage with a voltage threshold stored after being corrected during presetting, recognizing whether the fabrics are conveyed to a pressing pin as well as recognizing the number of the layers of the fabrics conveyed to the pressing pin, and controlling the pressing pin to raise and lower down and turn on and off the two feeding mechanisms according to the comparing result. The system is compact in structure, and low in requirement on a mounting space, replaces manual aligning, and realizes a full-automatic sewing machine.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and in particular relates to a system and method for controlling the end face alignment of double-layer fabrics of a sewing machine. Background technique [0002] In the field of semi-automatic sewing, diffuse reflection or through-beam proximity sensors are generally used to detect the presence or absence of pieces of cloth. For example, in the hemming process of trousers, the operator needs to align the front ends of the upper and lower trousers first, and then put them into the sensing area of ​​the proximity sensor. After the micro-controller receives the cloth signal, it drives the presser foot to move, the main shaft motor starts, and starts to sew. That is to say, this method can only distinguish two states with cloth and no cloth, but cannot distinguish three states of no cloth, single layer cloth and double layer cloth. [0003] However, in the field of fully automatic sewing, s...
