Embodiment 1
Below, in conjunction with the accompanying drawings, the principle of work that illustrates in greater detail knitting wool slubbing testing circuit of the present utility model with embodiment is as follows:
See Fig. 1, at first, as mentioned above, cathode power supply is (through K 1) through the light emitting diode D of parallel connection 1And resistance R 3After be conducted to SCR 1Emitter, be back to the 0V negative pole from its collector, form " normal signal " when fault (no) control loop.Cathode power supply is (through K 1) through light emitting diode D 2After be conducted to SCR 2Emitter, be back to the 0V negative pole from its collector, form " the first fault signal " (when first fault occurring) control loop.Cathode power supply is (through K 1) through controllable silicon SCR 3Emitter, collector after, by light emitting diode D 3Positive pole, be back to the 0V negative pole from its negative pole, form " the second fault signal " (when second fault occurring) control loop.
The triggering work of the control loop of above-mentioned " normal signal " is by capacitor C 1(about 0.8V) is provided.With C 1Parallel resistor R 1Behind power cut-off, play balancing capacitance C 1The effect of two terminal potential differences is convenient to switch on once more C 1Work provides controllable silicon SCR 1Control utmost point signal.
The triggering work of " the first fault signal " control loop and " the second fault signal " control loop is by Signal-controlled switch K 1Finish, its work is distinguished by resistance R 3And R 2Cooperation is finished.
The capacitor C of cross-over connection between " normal signal " loop and " the first fault signal " loop 2, after producing, can implement to cut off the normal signal loop when the first fault signal.Energized starts the knitting wool balling-up.The positive potential signal is through K 1, 8mm light emitting diode D 2, 0.1vF capacitor C 1, be added in SCR 1Silicon controlled control is extremely gone up, and triggers SCR 1The work conducting, show the D of no fault 1Lamp (green light) is bright.
As knitting wool fault process, make trigger switch K on the sense channel greater than the knitting wool slubbing of diameter range of control 2During conducting, then A point positive signal is through K 2, B point and R 2, add to SCR 2Silicon controlled control is extremely gone up, and triggers SCR 2The work conducting, pilot lamp (red light) D of demonstration fault 2Bright.
Work as SCR 2Work conducting, then capacitor C 2Right side discharge, SCR is passed through in its left side charging 1Excess current sharply reduce, and close voluntarily.At this moment, the pilot lamp D that shows no fault 1Lamp goes out.
Work as SCR 1Close, the current potential that A is ordered is because of R 3And raising, but K 2When not disconnected, R 3And R 2Dividing potential drop, at this moment, the signal that B is ordered is not enough to open SCR 3So,, the D of demonstration fault 3Lamp does not work.
After fault, K 2Disconnect C 2Charge to former power source voltage, the current potential that A is ordered has rising, thereby by sense channel, then this fault will make K once more if any fault 2Conducting, C 2On high voltage signal through A point, K 3, and the B point add to SCR 3Control extremely go up SCR 3Conducting at this moment, shows the pilot lamp D of fault 3Lamp is bright.
Repeatedly (individual) fault is to the SCR of an operate as normal 2And SCR 3There is no any influence, can keep present situation, make K 2Conducting.
After the balling-up knitting wool of revealing one and two or not having a fault is detected, classifies, can do return-to-zero and handle, that is, disconnect K 1, cutting off circuit, lamp goes out.Then, connect K once more 1, can make to return to initial situation.
In the present embodiment, controllable silicon has adopted the one-way SCR of 3DD51 model; Light emitting diode D 1Be the 5mm light emitting diode of BT301B, D 28mm light emitting diode for BT201F; C 2Electrochemical capacitor for 10vF.In the resistance, R 1Be the resistance of 470K ohm, R 2And R 3Be respectively the resistance of 2.4K and 4.7K ohm.
The main body and the passage of slubbing pick-up unit of the present utility model can be made into different shape.
Operating voltage in the present embodiment is 3+0.2V, power 0.05W.
In the present embodiment, it is a hollow and annular that slubbing detects main body, and its hollow bulb can grip on the guide bar that is fixed in the knitting wool sliver.At the other short roller of establishing of this pick-up unit main body, the sense channel of the lever jack formation knitting wool sliver of this short roller and knitting wool sliver and on detecting gate, the spacing between this short roller and the knitting wool sliver promptly constitutes the part of trigger switch.
In the present embodiment, the knitting wool balling-up is a unit with 40g, and the slubbing number of GB is in 2.Therefore, in the present embodiment, slubbing display lamp number is two, has two slubbing pilot lamp bright among a knitting wool balling-up process, is then taken out in addition by the operative employee to deal with.As in same knitting wool balling-up process, do not have or only have a slubbing pilot lamp bright, then can be used as Grade A.
Embodiment 2
See Fig. 3 and 4, other is with embodiment 1, and difference is, described knitting wool slubbing pick-up unit main body is one to be and to be roughly the box-like of rectangle.
According to the utility model, the traveling speed that is used to detect the knitting wool of slubbing can be more than 0.1 meter/minute, and the knitting wool of detection can be public of 6-20; Spacing between the fault of detection knitting wool can be more than 0.1 second.
Use accuracy of the present utility model is 100%; Its volume is small and exquisite, and mechanism is firm, and is easy for installation; And, operate, keep in repair easy.In addition, knitting wool slubbing of the present invention testing agency is not subjected to the influence of the dynamic dispatching of temperature, humidity, dust and knitting wool itself.
Use knitting wool slubbing pick-up unit of the present utility model, be close to the unit that has absolutely controlled balling-up knitting wool and contain the slubbing number, alleviated operative employee's manipulation strength, improved production efficiency.
