Technical field
The present invention relates to a kind of back Fabricating machinery of spinning machinery,, specifically when automatic winder carries out Yarn splicing, yarn is directed to the device of the passage of splicing in particular for the automatic winder of winding procedure.
Background technology
Winding procedure is a requisite operation in the spinning process, not only can be wound into cheese to the spun yarn cop through winding procedure, so that the later process use, and in the doff process, can remove yarn impurity and fault effectively, improve yarn quality.The tradition Spooling oquipment mostly adopts manual splice, the quality instability, and labour intensity and manpower consumption are all bigger; Automatic winder then has efficiently, at a high speed and high-quality advantage, it is the inevitable requirement of modern production that automatic winder replaces traditional bobbin-winding machine.
In the automatic winder running, when Yarn break or replacing spun yarn bobbin or removal yarn fault, all need to carry out splicing of yarn.This process of splicing is that splicer utilizes pressurized air to make upper and lower two one thread backtwistings, again twisting and twine incorporated high-quality knotless yarn mutually.At first, the big suction nozzle of automatic winder goes upward to the bobbin surface location from the initial position, and grasp the initial position that rotates back into it behind the loose thread on bobbin surface again by negative-pressure air-flow, this moment is because big suction nozzle has been positioned at the below of splicer, from making the last yarn stretch-draw that causes the bobbin surface between the suction inlet of bobbin and big suction nozzle, last yarn is directed to the pre-sth. made by twisting position of splicer front side.Meanwhile, the little suction nozzle that is positioned at the splicer lower position is drawn the yarn under working of spun yarn cop, and rotates up and yarn under working is brought to the position of splicing of splicer.Because the last yarn after the big suction nozzle extracting of quilt this moment is descending only is in pre-sth. made by twisting position, do not enter into the position of splicing of splicer, be arranged in catching the yarn hook and will going up the passage of splicing that the yarn hook is directed at splicer again of splicer, after splicer carries out clamping, cuts the yarn tail upper and lower yarn respectively again, carry out untwisting, twisting successively and finish splicing of upper and lower yarn.
Existing this splicing mechanism can realize splicing of upper and lower yarn preferably, this wherein the yarn hook of catching in the splicer be important Yarn splicing guiding device.Since this catch the yarn hook action must with upper and lower suction nozzle, especially descend the action of suction nozzle to coordinate correspondence mutually, so catching the yarn hook and being loaded between the suction nozzle on the frame in splicer all will be in transmission connection by cam, connecting rod mechanism, makes it reach the harmonious of action.Obvious this transmission device, though make catch yarn hook and little suction nozzle reach in the action synchronously, its transmission device is too complicated, cost is higher, especially movable parts is too much in this mechanism, causes and botches routines and the increase of fault rate.
For this reason, Chinese patent ZL95108170.5 discloses a kind of Yarn Connecting apparatus, this device will be arranged in the front end that the yarn hook directly is arranged at little suction nozzle of catching of splicer, like this after little suction nozzle suction goes upward to the splicer forward position toward yarn under working, little suction nozzle band yarn under working and is continued up and yarn under working is brought to the position of splicing of splicer, the yarn hook that sends on the little suction nozzle also will be gone up the position of splicing that the yarn hook is directed at splicer simultaneously, so that splicer is implemented to splice to upper and lower yarn.This mechanism has solved little suction nozzle preferably and has caught the harmony problem of moving between the yarn hook, transmission device is also simplified greatly, but since can do the rotating little suction nozzle in space and on the yarn of catching be hooked in when walking to the splicer top position, there is bigger space length on itself and splicer and the splicer between the guide plate, catch the yarn hook simultaneously to the guiding acting point of the last yarn also passage area of splicing in splicer not, the two combined action makes catches the yarn hook and will introduce the passage of splicing with going up yarn, must do one section longer distance " crossing guiding " to yarn, catch the yarn hook long distance of must on yarn, sliding and to go up the passage of splicing that yarn brings to splicer, cause the guiding traverse long, and this slip of catching yarn hook and yarn is easy to aggravate Yarn filoplume, even causes broken yarn.The increase of Yarn filoplume means the reduction of tieing quality again, is restricting the performance of automatic winder potentiality.Simultaneously, little suction nozzle and catch guide distance between plates on yarn hook and the splicer from increase, also make its yarn guide function become unstable, be guided yarn and depart from the passage of splicing easily, and occur yarn repeat splice.
