Description
Technical field
The invention belongs to industrial sewing technical fields, and in particular to a kind of bobbin thread for sewing machine peg or spindle rotation based on color sensing
Turn testing agency and detection method.
Background technique
The baseline of sewing machine is wrapped in inside peg or spindle, when sewing machine work, drives the dynamic of upper thread winding in eedle
Under power drive, peg or spindle is rotate at high speed.Lack and rotating shuttle or sewing machine machine operation in the starting of sewing machine work, baseline
In the case where exception, peg or spindle will appear abnormal working condition, that is, drive normal rotation without normal quilt cover line, cause
Baseline lacks when sewing, and structure ultimately causes the workpiece (such as ribbon etc.) of sewing above without baseline, results in this way
The intensity of sewing substantially reduces.Such case is in the field of the high requests such as safety belt, it may appear that fatal consequence, so stitching
While machine of threading works, become extremely important if it can monitor peg or spindle in real time and whether normally rotate.On the other hand due to shuttle
Core is running at high speed, and peg or spindle is mounted in inside bobbin case, is often difficult to judge whether rotating shuttle rotates, this is also much to stitch
It threads the problem of field face.Manually the mode of range estimation and breaking test carries out auxiliary judgment substantially at present, therefore, invention one
The bobbin thread for sewing machine peg or spindle rotation testing agency and detection method that kind is sensed based on color are necessary to solve the above problems.

When dynamic, peg or spindle 3 is freely rotated around mandrel with feeding ground thread；
S4: bobbin case 4 accommodates and is used to support peg or spindle 3, and center has a hollow shaft sleeve on shuttle frame 2, and by 6, shuttle door
Bobbin case 4 is fixed on shuttle frame 2, is not rotated with bobbin case 1 when work；
S5: in the color sensor 9 that the lower section of bobbin case 1 is arranged, when peg or spindle 3 normally rotates, color sensor is sentenced in real time
The switch logic of disconnected color: red -> blue -> green；If the switch logic sequence of color sensor real-time judge color: red
Color -> green -> blue, then may determine that peg or spindle not is normally to rotate, and the electric signal that color sensor will test passes to PLC,
PLC can acquire in real time the logical order of this color, and monitor in real time, once the sequence of color logic switch is not right, PLC can be sent out
Breath deliver letters to sewing machine, notifies sewing machine to stop working, PLC provides corresponding warning message simultaneously.
Working principle: it should be passed based on the bobbin thread for sewing machine peg or spindle rotation testing agency that color senses and detection method, color
Sensor detects the color change in coloring face 8, and optical signal is transmitted to photoelectricity stream transformer by photodiode or has color
The photodiode of filter forms, and photodiode is similar with light emitting diode, and core is also p-n junction, but photodiode
It is the converter for luminous energy being switched to electric energy.There are the window that illumination can be allowed to be mapped to photosensitive area, light on photodiode shell
Electric diode works under backward voltage.There was only faint reverse leakage current one dark electricity when no light, in the p-n junction of reverse bias
Stream passes through.Valence when the light-wave irradiation for thering is photon energy to be greater than p-n junction semiconductor material forbidden bandwidth, in each region of p-n junction
After Electron absorption photon energy, it will strain at the leass and become free electron, while generating a hole, these are generated by illumination
Free electron and hole are known as photo-generated carrier.In the area p and the area n far from depletion layer, because electric field strength is weak, photo-generated carrier
It can only make diffusion motion, disappear in diffusion process because compound, it is impossible to form photoelectric current.And due to electric-field strength in depletion layer
Degree is big, and photoproduction free electron and hole will be moved to the area n and the area p under electric field force effect with very big speed respectively, and reach electricity
Pole is moved along external circuit, forms photoelectric current.Direction by photodiode cathode to anode.Convert the light to photoelectric current.It can be with
Using external circuit, photoelectric current is converted into proportional voltage output, may then pass through analog-digital converter for voltage
It is converted into number format, is transported in microcontroller.The traditional method of sensed color is using three to four photodiodes
The structure of combination on one chip, and red, green, blue colour filter is placed in the surface of photodiode.Then it is converted by A/D
Module is converted into digital signal, is sent to PLC, and PLC can acquire in real time the logical order of this color, and monitor in real time, once
The sequence of color logic switch is not right, and PLC can send information to sewing machine, and notice sewing machine stops working, and PLC provides phase simultaneously
The warning message answered, invention design rationally, can judge completely shuttle with the working condition of the peg or spindle of real-time detection sewing machine
Whether core normally rotates clockwise or rotation counterclockwise, is worth promoting.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
