Embodiment
The utility model provides a kind of bobbin thread for sewing machine peg or spindle rotation detection based on color sensing as shown in Figs. 1-3
Mechanism, including bobbin case 1, the bobbin case 1 are internally provided with shuttle frame 2, peg or spindle 3 are plugged on the shuttle frame 2, the peg or spindle 3
It is provided with annular groove 7 outside two sides, coloring face 8 is provided on the annular groove 7, the side of the peg or spindle 3 is provided with bobbin case
4, open slot 5 is provided on the bobbin case 4, and the side of the bobbin case 4 is provided with shuttle door 6, and the side of the bobbin case 1 is provided with
L bracket 10, the side of the L bracket 10 have been bolted to connection sensor stand 11, the sensor stand 11
On color sensor 9 is installed.
Specifically, multichannel color mark sensor of the color sensor 9 using Keyence, concrete model CZ-H32,
The detector of the color sensor 9 is located at the underface of open slot 5.
Specifically, being coated with the paint of three kinds of colors of RGB on the coloring face 8, the sequence coloured on the coloring face 8 is
It is red, blue, green.
A kind of detection method of the bobbin thread for sewing machine peg or spindle rotation testing agency based on color sensing, should be sensed based on color
Bobbin thread for sewing machine peg or spindle rotation testing agency detection method specific step is as follows:
S1: bobbin case 1 is fastened in lower axle with screw, is transported with annular guiding tooth high speed of the 2nr/min revolving speed on shuttle frame
Turn, the needle thread loop of pin hole attachment is pierced into using the spur on bobbin case 1；
S2: the mandrel of 2 bottom center of shuttle frame is for supporting bobbin case 4 and peg or spindle 3；
S3: 3 loop of peg or spindle is the coil holder for being wound with shuttle thread on the mandrel of bobbin case 4, when sewing, when shuttle thread is taken out
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: testing agency should be rotated based on the bobbin thread for sewing machine peg or spindle that color senses, color sensor detects
Optical signal is transmitted to photoelectricity stream transformer by photodiode or with the light of color filters by the color change in coloring face 8
Electric diode composition, photodiode is similar with light emitting diode, and core is also p-n junction, but photodiode is that luminous energy is turned
For the converter of electric energy.There are the window that illumination can be allowed to be mapped to photosensitive area, photodiode work on photodiode shell
Make under backward voltage.When no light, only have faint one dark current of reverse leakage current to pass through in the p-n junction of reverse bias.When
When the light-wave irradiation for having photon energy to be greater than p-n junction semiconductor material forbidden bandwidth, the valence electron in each region of p-n junction absorbs light
After sub- energy, will strain at the leass and become free electron, while generate a hole, these by illumination generate free electron and
Hole is 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 can only be spread
Movement, disappears in diffusion process because compound, it is impossible to form photoelectric current.And since electric field strength is big in depletion layer, 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 electrode along external circuit
Movement forms photoelectric current.Direction by photodiode cathode to anode.Convert the light to photoelectric current.External electrical can be used
Photoelectric current is converted into proportional voltage output by road, be may then pass through analog-digital converter and is converted voltage to number
Format is transported in microcontroller.The traditional method of sensed color is to combine using three to four photodiodes at one piece
Structure on chip, and red, green, blue colour filter is placed in the surface of photodiode.Then it is converted by A/D conversion module
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 color logic is cut
The sequence changed is not right, and PLC can send information to sewing machine, and notice sewing machine stops working, and PLC provides corresponding alarm signal simultaneously
Whether breath, utility model design rationally, can judge peg or spindle completely with the working condition of the peg or spindle of real-time detection sewing machine
It normally rotates clockwise or rotates counterclockwise, be worth promoting.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
