Abstract
The present invention relates to a method for removing the end of coils of wound thread, in particular for linen yarns, which are deposited and cling tightly to the area around the clamping line between the fixed counter-pin of the arm of the bobbin-holder and the end of the smallest diameter of the small tube, and said coils are formed each time the thread being wound comes out of the smaller side of the basically flat-tapered bobbin in formation owing to an interruption in the winding.
Description
The present invention relates to remove outwards method around thereon coiling afterbody from the bobbin that is essentially gentle tapers of positive coiling.
The present invention is specifically related to aspirate the method for removing the coiling afterbody, this coiling afterbody continuously is wrapped on the fixing circumferential area to the annular arrangement clamping element between vertical pin and the tubule minimum diameter end of support for bobbin arm, this method can be applied in the wire coiling machine, particularly is applied in bobbin to twine in the automatic coil winding machine of line.
Under present state of the art, used the automatic coil winding machine of the support for bobbin arm that the band dop is housed, this support for bobbin arm have one fixing to vertical pin and one movable to vertical pin, the effect of these pins is fixedly tubules of supporting, fixed neutralization, but also makes yarn on tubule.The shape of coiling bobbin is roughly mild taper usually, so that move back line in the next process in textile mills easily.
In the operating process of each broken string and knotting; or when each falls back on the end of yarn for bobbin; usually this thing happens in meeting; be the final stage line since be not subjected to any tension force and since the bobbin that is just twining for conical, so leave bobbin easily and be wrapped in corresponding to pipe fixing than minor diameter on the vertical pin.Therefore, this section alignment slides into the sidepiece of the mild conical bobbin of reeling outward, because the continuous rotation of bobbin, this section line just is wrapped in the fixing circumferential area to the annular clamping element between the end of vertical pin and pipe minor diameter of support for bobbin arm, and this winding is very tight around on the vertical pin, so be difficult to withdraw from, thereby need be with the fixedly line end that blocks on the suction tube of top.Be familiar with the technical personnel of this technology and all know, this around the yarn winding on the vertical pin can not be withdrawed from and take out from suction tube during knotting subsequently, thereby after trying to start several times, winding process has just interrupted fully.The result is, one interrupts when bobbin twines, and winding operation just stops, thereby the personnel that need repairing intervene.This intervention requires a part of maintainer to keep an eye on meticulously, and this forces this part personnel to intervene without any Fixed Time Interval ground.Clearly, thisly accidental do and reduced the part work efficiency of workers.
In prior art, recommended and proposed each six kinds of method to prevent or limit yarn outwards by the side of the bobbin of positive coiling.
For example a method of Cai Yonging is to use the flat board member of suitable shape, is placed on two ends of bobbin of positive coiling, thereby places on two ends of protruding shape yarn roller.Even above-mentioned expedient method has reduced this phenomenon, still exist yarn around to the problem on the vertical pin, though degree is light.Though this countermeasure is used widely, still have very big defective, promptly it makes structure become complicated, has hindered whole winding operation.Go to the sidepiece of bobbin for fear of yarn, another method that prior art proposes is to spray pressurized air, forces yarn to be stayed on the surface of bobbin.Though a kind of device in back is to preventing that yarn from leaving bobbin improvement is arranged, yarn still every now and then around the support for bobbin arm on the vertical pin, thereby this method does not provide a kind of permanent terms of settlement for the problems referred to above.In order to satisfy yarn conventional all requirements that distribute on bobbin, these methods and other method of being proposed by known technology have proved slippery, reason is, these methods all make yarn tightly on the circumference that is entangled in vertical pin, thus to remove this yarn and and then the operation of tiing a knot be very difficult.
According to the research to above-mentioned shortcoming, applicant of the present invention is surprised to find that, uses method and apparatus of the present invention, can remove from the sidepiece of the bobbin of positive coiling with extreme operating reliability whenever yarn falls down just.Method as herein described can remove tightly be wrapped in the support for bobbin arm fixing to vertical pin and coiling pipe than the coiling afterbody winding on the clamping element circumferential area between the end of minor diameter, this method is included in the grappling end of support for bobbin arm in embodiment can carry out limited axially opening, whenever coiling is interrupted, particularly before removing the yarn top afterbody yarn that is wrapped on the bobbin, just carry out this operation of opening, so that can reset winding operation in the startup suction operation.
Be substantially equal to vertical pin extend into half of length in the yarn winding supporting pore at the pin of support for bobbin arm with to this axially degree of stretching out between the vertical pin, in addition, thisly axially open operation and accurately occur in the moment that begins to aspirate the top afterbody yarn that is wrapped on the bobbin that just is shaped.The embodiment of the inventive method is made of an equipment.This equipment has a pneumatics or any known devices, and this device moves a lever when each knotting operating process begins, by the pin of this lever control line bracing strut arm with to the opening width between the vertical pin.
Optimization embodiment of the present invention is described below with reference to the accompanying drawings, and this embodiment only is used for casehistory the present invention, does not limit the present invention.

Fig. 2 is total schematic front view on wire coiling machine top, this illustrates that yarn disconnects or in some cases during the yarn flow disruption, and yarn is in fixing vertical pin and bobbin are twined some circles than the clamping element circumferential area between the end of minor diameter the moment of support for bobbin arm.
Fig. 3 is the total schematic front view in wire coiling machine top, and this illustrates the device of realizing the inventive method in the wire coiling machine has made the anchor end of support for bobbin arm carry out limited axially opening, thereby can remove the moment of coiling afterbody with suction cylinder.
In order better figure to be described, whole getting on very well saved in the drawings to N/R parts of the present invention, because these ones are well-known, and do not relate to function of the present invention.
In the accompanying drawings, the 1st, knitting wool, cotton thread or synthetic line, in the coiling process, these lines are transferred and the wire bar pipe 14 below bobbin or top bobbin 2 is resigned from office.This bobbin is used for the spinning 1 around different shape, and coiled is roughly spiral winding; The 3rd, known devices is preferably pneumatics, axially the opening vertical pin 15 and pin 12 of its control wire bracing strut arm 27; The 4th, three phase electric machine or similar propulsion source, it drives lead cylinders 29 by cog belt 28.This lead cylinder is a head roll, and it makes the 1 forward and backward motion that spins, and the bobbin 2 of positive coiling is rotated, until the coiling that spins is to the diameter that needs; The 5th, suction tube, one end are shaped as a seam, are used to aspirate the afterbody that spins on the bobbin 2 of positive coiling.Suction tube 5 is known in prior art, 1 controllably interrupts or during accidental the interruption, this suction tube just starts whenever spinning, and this starting is to utilize starter 18 to carry out angular turn, and this starter 18 is controlled by electric wire 19 by controll block 20; The 6th, by the lever that device 3 promotes, this device makes solid pivot 9 shift to the fixed middle pin 27 of support for bobbin arm 27; The 7th, detector, it illustrates cutting cylinder 29 at each rotating speed constantly, and continuously this tachometer value is sent on the controll block 20 by cable 25; The 26th, 1 cable that has a sensor spins; 20 are based on the controll block of microprocessor or electronic cards, and it is suitable for remembering by the instruction of supervisory keyboard 22 by cable 21 inputs.This controll block 20 can become a program with the instruction transformation by cable 21 inputs, thereby is provided at necessary signal in the coiling process continuously, and this program obtains by the computation center of controll block or the processing of processing enter.Controll block 20 be we can say and resembled a micro controller system substantially, it uses the information from disc type detector 7 (by cable 25) and cable 26 as inlet, also use information from cable 23, cable 26 detects the existence that spins with its detector, cable 23 transmits the signal that control spins with its detector, this spins must be the electronics control desks that spin through detecting the detection of piece 10, detecting piece 10; The 16th, clutch part is used for tensioning equably and just spins 1 what move on the bobbin 2.The 8th, motorized valve or similar device, when by cable 24 when controll block 20 obtains signal, this motorized valve makes motor 11 startings of drive fluid, this fluid makes with actuator 3 vertical pin 15 is taken place axially to open, thereby forms the embodiment of the inventive method.
Operation instructions below with reference to above-mentioned accompanying drawing is applicable to the device of implementing the inventive method, and can understand above-mentioned operation at an easy rate from above-mentioned accompanying drawing.
In the weaving wire coiling machine, for example in the automatic bobbin winder, spin 1 intersecting the mode of winding on the bobbin 2 that is called reel from what spindle pipe 14 withdrawed from, or on the bobbin that is suitable for use in the operation subsequently.When spinning 1 when spindle pipe 14 is sent on the bobbin 2, the detection of piece 10 after testing that spins, this detection piece is the known electronics controller that spins.When detecting when having spinned undesirable defective, the analysis circuit of the controller 10 that spins just triggers the outgoing pulse of an electricity and enters into controll block 20.This controll block 20 produces the cut-out request pulse of an electricity thus, and making spins 1 cuts off, and starts the knotting operating process at the same time, and this knotting operating process has been moved back line when coiling is interrupted at the spindle pipe, perhaps also will be started when spinning disconnection accidentally.Should be noted that in the good winder of regulation and control the chance disconnection of yarn 1 is seldom.Require to cut off to spin at 1 o'clock each time, or when controlled or accidental interruption yarn 1 each time, recurrent thing is, afterbody yarn 1 has always twined some circles fixing on to vertical pin 15.In fact outwards slide into that other one section of the side that is roughly mild conical bobbin 2 spins because the continuous rotation of bobbin and the clamping element circumferential area between vertical pin 15 and the little tube end is being wrapped with some circles.Begin the operating process of tiing a knot under the starting of controll block 20, this controll block drives motorized valve 8 subsequently or simultaneously, the device 3 that the control of this valve is moved lever 6 and pivot 9, thus make the pin 12 of support for bobbin arm 27 and axially open taking place between the vertical pin 15.Thereby slowed down to spin and 1 tightly be entangled in the speed of wrap on vertical pin 15 circumference, so the line that twines can easily and apace be aspirated out by suction cylinder 5, begin the operating process of tiing a knot subsequently.Thereby the winding operation process is restarted reliably.The result is.The bobbin 2 of positive coiling can wind the line and needn't be by forced-stopping machine continuously.
The optimization embodiment that some variation can be arranged has been described above, has clearly also had the embodiment of other form that meets spirit and scope of the invention.
