Problems solved by technology

But it still has some deficiencies: its thickness detection sensor function is only used to detect the thickness of the cloth, when the thickness detection sensor does not need to work to detect the thickness of the cloth at the end of sewing or stops midway, its thickness detection sensor is idle and does not work, resulting in Reduce the waste of resources, do not use to improve work efficiency

Embodiment 1

[0025] Such as figure 1 As shown, the multifunctional sensor control system includes:

[0026] S1. During normal sewing, the control switch does not work, the thickness detection device is used to detect the thickness of the fabric, and the controller adjusts the motor speed according to the detected thickness of the fabric; the function realized here is the first function of the thickness detection device, and it is also a conventional function. When the sewing machine is sewing normally, the presser foot is pressed on the fabric, and the height of the presser foot changes due to the different thickness of the fabric. The thickness detection device detects the change in the thickness of the fabric according to the change in the height of the presser foot, and feeds back the change to the electric control of the sewing machine. , After the sewing machine is electronically controlled, the output control signal controls the motor speed to adjust accordingly according to the chan...

Embodiment 2

[0034] Such as figure 2 As shown, the multifunctional sensor control system includes a thickness detection device, an electromagnet for lifting the presser foot, a knee rest mechanism and a controller. Both the electromagnet for lifting the presser foot and the knee rest mechanism are used to drive the lift of the presser foot. The knee rests on the pan, and the control switch is installed on the knee rest mechanism.

[0035]A control switch is also included, and the control switch is used to identify the knee rest action of the knee rest mechanism, wherein the control switch is one of a Hall switch, a proximity switch and an angle sensor. The controller is used to control the thickness detection device to detect the thickness of the fabric during normal sewing, adjust the motor speed according to the detected thickness of the fabric, and when switching to abnormal sewing, it is used to start the control switch, and when receiving the knee from the control switch When relyin...

Abstract

The invention provides a control method and a control system for a multifunctional sensor, and belongs to the technical field of sewing machine control, solving the problem of resource waste caused bythe fact that thickness detecting sensors of existing sewing devices are idle after sewing is stopped. The control method includes that S1, during normal sewing, a control switch does not work, a thickness detecting device is used for detecting the thickness of cloth, and a controller adjusts the motor speed according to the detected thickness of the cloth; S2, when the normal sewing is switchedto abnormal sewing, the controller starts up the control switch to work, and the control switch starts to work to recognize an action of a knee pedal; S3, when the control switch recognizes the actionof the knee pedal, the controller controls a presser foot lifting electromagnet to output an initial force, controls the thickness detecting device to be switched to a detection height of a presser foot, and adjusts the output force of the presser foot lifting electromagnet so as to enable the force of the knee pedal for lifting the presser foot to be constantly a small force. The control methodhas the advantages of high resource utilization rate and simple structure.

Description

technical field [0001] The invention belongs to the technical field of sewing machine control, and relates to a multifunctional sensor control method and system. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, hemp, silk, wool, and artificial fibers, and products such as leather, plastic, and paper. convenience. At present, sewing machines are mainly divided into two categories: household sewing machines and industrial sewing machines. Among them, industrial sewing machines include lockstitch sewing machines, chain sewing machines, overlock sewing machines and interlock sewing machines. A sewing machine generally consists of a machine head, a machine base, a transmission mechanism and a control mechanism. The machine head is an important part of a sewing machine, i...
