Description
Technical field
The present invention relates to a kind of precursor doff tail yarn automatic stop arrangement.
Background technology
Existing roving production process, there is the thorough problem of residual tail yarn doff, problems normally produces rove workshop section and rove product quality causes certain influence, and workman changes yarn operating process complexity, and tail yarn allowance is uneven, and precursor waste is more.Do not have relevant device to ensure this technical requirement at present, tail yarn shut-down operation can only be completed by workman's experience.
Summary of the invention
The technical problem to be solved in the present invention is that existing roving need of production manually changes yarn, and to solve the not thorough problem of residual tail yarn doff, operating process is complicated, and tail yarn allowance is uneven, and precursor waste is more.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of precursor doff tail yarn automatic stop arrangement, comprising: mechanical device: comprise base plate, depression bar, n root spring push-rod, described n >=1; Depression bar one end is rotatably connected bottom base plate, and the other end is free operant end, and middle part is by stay cord linking springs push rod; The front end of described spring push-rod arranges pressure head, and tail end all connects depression bar by stay cord through base plate; Electrooptical device: comprise reflection photoelectric detector and circuit control box, described reflection photoelectric detector is arranged in bottom plate, the input of its output connecting circuit control cabinet.
Precursor tail yarn is clamped by mechanical device by the present invention, and by the allowance of the precursor tail yarn of electrooptical device timely detection mechanism clamping place, and it is on time not up to standard in tail yarn amount to control Speed frames, stops in time, thus reaches the object of tail yarn automatic stop.The operation principle of reflection photoelectric detector carries out coherent detection to tail yarn height, to reach the control to tail yarn quality.
In order to strengthen the smoothness that mechanical structure clamps tail yarn, spring push-rod is also provided with spring guide rail, spring is positioned at spring track telescopic movable.Because spring can only promote push rod work in the stroke range that spring track is confined, therefore, smoothness is higher.
In order to easy to operate, circuit control box comprises time relay sj, auxiliary reclay J, diode, frequency converter VF, indicator lamp and photovoltaic element; Described indicator lamp comprises power supply indicator and parking indicator lamp, and power supply indicator, time relay sj, photovoltaic element are in parallel, the output series connection auxiliary reclay J of photovoltaic element, the normally closed switch of auxiliary reclay J and time relay sj series connection; The contact switch of time relay sj, frequency converter VF, the series connection of parking indicator lamp, described photovoltaic element comprises the photoelectricity group of a more parallel, and each photoelectricity group is made up of a photoelectric sensor and a Diode series.
In order to strengthen the clamping of precursor tail yarn, described stay cord adopts steel wire rope, and the number of steel wire rope is more than one, and every root steel wire rope is connected with many push rods.When lower moulded rod, drive steel wire rope to affect spring push-rod action, because every root steel wire rope is connected with many spring push-rods, ensure that the many spring push-rod actions that same steel wire rope connects are synchronous.
Advantage of the present invention is: effectively improve the tail yarn allowance problem of non-uniform that precursor doff produces in rove process, move back precursor doff outside independent development development and stay tail automatic stop arrangement, the precursor tail yarn controlling to produce in rove production process is beated, tail yarn allowance problem of non-uniform, controls precursor tail yarn amount with concrete mechanical optoelectronic device.Thus replace the control of operating personnel's experience, enhance productivity, improve finished product rate, improve precursor utilization rate, reduce labor strength, existing creel basis independently can be installed, and tail yarn clamping effect is stablized.
Accompanying drawing explanation
Fig. 1 is structural representation side view of the present invention.
Fig. 2 is structural representation top view of the present invention.
Fig. 3 is the circuit diagram of circuit control box of the present invention.
Detailed description of the invention
As Figure 1-Figure 2, depression bar 1 tail end of the present invention is connected with base plate 2, and middle part is connected with spring push-rod 4 through after base plate 2 by steel wire rope 7, and front end is free end, for operator's depression, precursor tail yarn is clamped by the pressure head 3 of rubber mushroom head by spring push-rod 4.
Ensureing on the basis that precursor yarn is stable, during reflection photoelectric detector 5 pairs of precursor amounts, row detects in time, then by testing result Signal transmissions to circuit controller 6, the relay delay process in circuit controller 6, after judging the authenticity of signal, control thick line machine in time and stop.
When yarn starts doff, spring push-rod 4 is in compressive state, and reflection photoelectric detector 5 accepts lasting light electrical feedback signal.When winding yarn is less to precursor tail yarn amount, now precursor yarn group has trace to beat, and the spring in the middle part of spring push-rod 4 transforms into by original compressive state the state of flicking, and supports precursor tail yarn, avoid precursor tail yarn because of broken yarn of beating, reduce the impact of doff process on reflection photoelectric detector simultaneously.When precursor tail yarn amount reduces to prescribed limit (tail yarn amount≤30g), tail yarn height is about 10-15mm, now reflect photoelectric detector 5 and send signal because there is no the stop of yarn, and do not receive feedback signal, reflection photoelectric detector 5, by circuit control box, realizes Speed frames automatic stopping function.
As shown in Figure 3, circuit control box comprises time relay sj, auxiliary reclay J, diode, frequency converter VF, indicator lamp and photovoltaic element; Described indicator lamp comprises power supply indicator and parking indicator lamp, and power supply indicator, time relay sj, photovoltaic element are in parallel, the output series connection auxiliary reclay J of photovoltaic element, the normally closed switch of auxiliary reclay J and time relay sj series connection; The contact switch of time relay sj, frequency converter VF, the series connection of parking indicator lamp, described photovoltaic element comprises the photoelectricity group of a more parallel, and each photoelectricity group is made up of a photoelectric sensor and a Diode series.
Circuit theory control procedure is as follows: precursor tail yarn moves back separates specified altitude, photoelectric sensor is to auxiliary reclay J signal, normally closed switch J disconnects, the S pole dead electricity of time relay sj, after 2-3 time delay second, the time relay sj closing of contact, passes to frequency converter VF by signal, then completes parking by frequency converter VF.
Aforementioned diodes effect avoids the photoelectric sensor in parallel connection mutually to disturb, unidirectional blocking-up electric current.When wherein there being a photoelectric sensor to send stop sign, if there is no diode, the signal designation lantern festival that all photoelectric sensors carry together lights, and can not determine which photoelectric sensor concrete sends to obtain signal, so can not find the place needing to change yarn the very first time.Add diode can avoid mutually disturbing between photoelectric sensor.
Above-mentioned precursor doff tail yarn automatic stop arrangement: mechanical device by effectively fixing for precursor tail yarn, effect be when precursor move back separate fast at the end of, avoid precursor tail yarn vertical tremor.And optoelectronic device is on the basis of machinery firm precursor tail yarn, detect tail yarn allowance.By the detection of optoelectronic device to precursor group height, control precursor tail yarn weight, when precursor tail yarn amount reduce to one to degree time, optoelectronic device sends feedback signal, controls spooler and stops in time.Cooperatively interacting of mechanical device and optoelectronic device, reaches the object of tail yarn automatic stop.
