Description
Technical field
The invention belongs to sewing machine technique field, be specifically related to a kind of there is broken string and cloth detection function
Sewing machine.
Background technology
Sewing machine, during sewing, is understood due to factors such as mechanism is bad, cloth thickness, suture quality,
Cause the situation of broken string.As do not found in time, cloth can be damaged, produce defective products, waste product, impact
Quality, causes economic loss simultaneously.It is thus desirable in time broken string is detected, and do corresponding process.
At present burn out detection mainly has an in the following manner:
1. clothing is checked by macroscopy, i.e. direct labor in sewing process, and this mode can be rule of thumb
There is bigger delay, and sewing machine rotating speed be generally very fast, time to be found, late, for semi-automatic,
Full-automatic sewing device is not suitable for；
2. mechanism type, i.e. by frame for movement, as spring hooks suture and is connected with mechanical switch, broken string
Time machinery switch contact or disconnection, thus produce control signal.This scheme device directly contacts with sewing thread,
Existing and affect stitching, structure is complicated, is unfavorable for the shortcoming that automatization sews；
3. laser opposite-radiation: sewing thread need to pass between launching and receiving, and installation is difficult to, and laser is deposited
In the shortcoming that the life-span is shorter, and cost is more expensive.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem and provide one to have broken string and cloth inspection

Cloth detector, for sending disconnected cloth signal when detecting that cloth is used up；
Motor driver, is connected respectively with described thread break detector, cloth detector, for receiving
After described disconnection signal or disconnected cloth signal, send motor and stop signal；
Servomotor, is connected with described motor driver, stops fortune for stopping signal according to described motor
OK.
Described thread break detector includes multichannel vibrating sensor.
Vibrating sensor described in every road connects a switch, for controlling opening of vibrating sensor described in every road
With with disable.
Described cloth detector includes that multichannel diffuses electric switch.
The electric switch that diffuses described in every road connects one and controls switch, is used for controlling diffuse-reflectance described in every road
What light was established by cable enable and disable.
Described motor driver connects alarm lamp, can stop because of broken string or disconnected cloth at described servomotor
Machine sends default light to carry out indicating and/or carrying out alert audio prompting simultaneously.
The present invention detects broken string, disconnected cloth situation in real time by thread break detector and disconnected cloth detector, and is inciting somebody to action
Detection signal is sent to motor driver, by motor driver according to this broken string, disconnected cloth signal output motor
Stopping signal, to servomotor, makes servomotor stop, it is achieved thereby that the broken string of automatization, disconnected cloth inspection
Survey, and ensure that accuracy and the accuracy of detection.

Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features and the advantage of the present invention are further described, but this
Bright it is not limited to listed embodiment.
See shown in Fig. 1-5, a kind of sewing machine with broken string and cloth detection function, including:
Thread break detector, for sending disconnection signal when broken string being detected；
Cloth detector 30, for sending disconnected cloth signal when detecting that cloth is used up；
Motor driver 80, is connected respectively with described thread break detector, cloth detector, for receiving
After described disconnection signal or disconnected cloth signal, send motor and stop signal；
Servomotor 70, with motor driver 80, is used for stopping signal according to described motor out of service.
The present invention detects broken string, disconnected cloth situation in real time by thread break detector and disconnected cloth detector, and is inciting somebody to action
Detection signal is sent to motor driver, by motor driver according to this broken string, disconnected cloth signal output motor
Stopping signal, to servomotor, makes servomotor stop, it is achieved thereby that the broken string of automatization, disconnected cloth inspection
Survey, and ensure that accuracy and the accuracy of detection.
In the present invention, described thread break detector includes multichannel vibrating sensor, preferably 8 tunnels.
Implementing, vibrating sensor described in every road connects a switch, is used for controlling to shake described in every road
The enabling and disabling of dynamic sensor.
Concrete, described thread break detector can be multiple, it is also possible to is one, as in figure 2 it is shown, should
Illustrate the situation of two thread break detectors, such as the first thread break detector 10 and the second wire clipper 20,
It is respectively used to corresponding 16 lines are carried out burn out detection.
The disconnection of the line that described broken string refers to.
In the present invention, described cloth detector includes that multichannel diffuses electric switch, preferably 8 tunnels.
Implementing, the electric switch that diffuses described in every road connects one and controls switch, is used for controlling often
Diffuse described in road enabling of establishing by cable with disable.
Further, described motor driver connects alarm lamp 40, can be at described servomotor because of disconnected
Line or disconnected cloth and shut down and send default light and indicate, such as red colored lamp and/or carry out alarm sound simultaneously
Frequency prompting.
Described display lamp, can be tri-colour LED, it may also be used for other instruction, as artificial at sewing machine
