Abstract
The invention provides a time-sequence control method for pipe replacement of an automatic bobbin winder. The time-sequence control method is characterized in that when a cop sucker descends from the starting position to grab yarns and a yarn feeding sensor judges that no yarn exists, the cop sucker continuously ascends to the working position of a twist connector, a yarn pre-clearer and a tension bowl are opened, and then the yarns are cut off by scissors; when the cop sucker ascends continuously to be matched with a twist connector support and is opened, a section of yarns cut off is sucked into a negative-pressure pipeline by negative pressure, and then the cop sucker descends to the starting position, pipe replacement is carried out by a single-spindle pipe replacer, after the pipe replacement, the cop sucker returns to the starting position and prepares the next twist connection circulation. Two or more yarns are effectively avoided from being grabbed by the cop sucker, and twist connection failure caused by the fact that multiple yarns are fed into the twist connector by the cop sucker is avoided, production efficiency is improved, and waste of the yarns is reduced. Further, the control method is simple and convenient, and no equipment needs to be modified.
Description
Technical field
The invention belongs to technical field of textile machine, relate to the improvement of automatic winder control method, is a kind of automatic winder replace tubes sequential control method specifically.
Background technology
Be designed with the lower scissors structure on the ESPERO automatic winder list ingot, if yarn sensor judges that the cop suction nozzle has grabbed yarn down, lower scissors is failure to actuate, and the circulation of proceeding to splice; If following yarn sensor judges when the cop suction nozzle does not grab yarn, scissor action once, cut off because of yarn sensor erroneous judgement down by the yarn of cop suction nozzle extracting, avoid the cop suction nozzle to grab the possibility of two or threads simultaneously.
At present, SPERO that releases on the market and SMARO automatic winder do not have the lower scissors structure, when the cop suction nozzle grabs yarn; And down the yarn sensor erroneous judgement when not having yarn; Single ingot will carry out the replace tubes action, causes the cop suction nozzle to catch two or threads, causes the circulation of splicing unsuccessful; Influence production efficiency, the waste yarn; Perhaps, yarn one end is grasped by the cop suction nozzle, and the spool of being chosen is followed the blank pipe load-transfer device and moved ahead, and causes yarn to be wrapped in the phenomenon on the fuselage.
Summary of the invention
The present invention is directed to the problems referred to above that prior art exists; A kind of automatic winder replace tubes sequential control method is provided; Effectively prevention cop suction nozzle grabs the phenomenon of two or threads simultaneously; Avoided having improved production efficiency, reduced the yarn waste because of the cop suction nozzle causes the unsuccessful problem of splicing with two or threads feeding splicer.And control method is easy, need not reforming equipment.
The objective of the invention is to realize through following technical scheme:
A kind of automatic winder replace tubes sequential control method; Comprise controller, cop suction nozzle, cop suction nozzle transmission device, yarn sensor, splicer, splicer support, yarn clearer, tension pulley, scissors, negative-pressure pipeline, single ingot replace tubes mechanism in advance down; Said controller is used to receive down the signal and up, the descending action of control cop suction nozzle that yarn sensor sends; It is characterized in that replace tubes sequential control method step is:
When the cop suction nozzle by reference position descending grab yarn after, and down yarn sensor is judged as when not having yarn, it is up that the cop suction nozzle continues, and goes upward to the position of splicer work, yarn clearer is opened with tension pulley in advance, scissor action is cut off yarn at this moment; The cop suction nozzle continues up, cooperates with the splicer support, and the cop suction nozzle is opened, and one section yarn cutting off relies on negative pressure to be sucked into negative-pressure pipeline; Then, the cop suction nozzle comes downwards to original position, carries out the replace tubes action by single ingot replace tubes mechanism, and after replace tubes finished, the cop suction nozzle came back to original position, prepared to splice circulation next time.
Improvement to technique scheme: said cop suction nozzle is 10 °-20 ° by reference position to the rotational angle that grabs yarn; The cop suction nozzle is 120 °-140 ° by the rotational angle that the position that grabs yarn goes upward to the splicer control position; It is 5 °-15 ° that the cop suction nozzle goes upward to the rotational angle that the splicer support makes cop suction nozzle open position by the splicer control position.
Advantage of the present invention and good effect are:
The misoperation problem that the automatic winder that the present invention is directed to does not have lower scissors runs in the doff process; A kind of automatic winder replace tubes sequential control system is provided; Effectively prevented the cop suction nozzle to grab the phenomenon of two or threads simultaneously, avoided causing the unsuccessful problem of splicing because of the cop suction nozzle feeds splicer with threads.Improve production efficiency, reduced the yarn waste.
Description of drawings
Fig. 1 is the principle of work scheme drawing of a kind of automatic winder replace tubes of the present invention sequential control method;
Fig. 2 is the FB(flow block) of a kind of automatic winder replace tubes of the present invention timing method.
The specific embodiment
Referring to Fig. 1, Fig. 2, the embodiment of a kind of automatic winder replace tubes of the present invention sequential control method,
Comprise controller, cop suction nozzle 2, cop suction nozzle transmission device, yarn sensor 1, splicer, splicer support 3, yarn clearer, tension pulley, scissors, negative-pressure pipeline, single ingot replace tubes mechanism in advance down; Said controller is used to receive down the signal and 2 up, the descending actions of control cop suction nozzle that yarn sensor sends, and replace tubes sequential control method step is:
Grab after yarn position A grabs yarn when cop suction nozzle 2 is come downwards to by reference position D, and yarn sensor 1 is judged as when not having yarn down, cop suction nozzle 2 continues up; Go upward to the position B of splicer work; Yarn clearer and tension pulley are opened in advance, and this moment, scissor action was cut off yarn; Cop suction nozzle 2 continues to go upward to position C, cooperates with splicer support 3, and cop suction nozzle 2 is opened, and one section yarn cutting off relies on negative pressure to be sucked into negative-pressure pipeline; Then, cop suction nozzle 2 comes downwards to reference position D place, carries out the replace tubes action by single ingot replace tubes mechanism; After replace tubes finished, cop suction nozzle 2 came back to reference position D place, prepared to splice circulation next time.
In the above-mentioned control method: cop suction nozzle 2 by reference position D to the rotational angle that grabs yarn position A be 10 °-20 °; Cop suction nozzle 2 is 120 °-140 ° by the rotational angle that the position A that grabs yarn goes upward to splicer control position B; It is 5 °-15 ° that cop suction nozzle 2 goes upward to the rotational angle that splicer support 3 makes cop suction nozzle 2 open position C by splicer control position B.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; Those skilled in the art; In essential scope of the present invention, the variation of having done, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
