Abstract
The invention discloses an unwinding device for back-wound tail yarn. The unwinding device comprises a motor bracket arranged on a tail yarn cleaner frame, a driving motor is mounted on the motor bracket, an output shaft of the driving motor is connected with a bobbin seat, a bobbin is disposed on the bobbin seat, a switch bracket is arranged on the motor bracket, a proximity switch is arranged on the switch bracket, a sensing surface of the proximity switch is flush with the top of the bobbin, and the proximity switch is connected with a controller of a tail yarn cleaner. The controller of the tail yarn cleaner is used for controlling turning of the output shaft of the driving motor. When tail yarn is unwound, the bobbin rotates reversely at high speed, back-wound yarn heads originally adhering to a forwards-wound tail yarn layer rotate forwards after being thrown off, a suction nozzle of the tail yarn cleaner can find the unwound tail yarn heads smoothly and rapidly, and accordingly working efficiency of the tail yarn cleaner is improved, and further conveying efficiency of a thick-thin joint conveying system is improved.
Description
Technical field
The present invention relates to field of textile machinery, relate in particular to a kind of take-off device of the tail yarn that rewinds.
Background technology
Along with the raising of textile machine degree of automation, the widespread use of thickness connection equipment, the cleaning work of empty spool tail yarn becomes more and more important, therefore, has occurred tail yarn scavenger on market.Tail yarn scavenger is mainly used in thickness contact system the tail yarn on the used flyer bobbin of spinning frame and is adsorbed on useless on stick spending automatic removing clean, again by automatic conveying system during for the automatic repiece of fly frame directly, labour power has been saved in the appearance of tail yarn scavenger greatly, has improved production efficiency.
Yet in the use procedure of thickness connection full automaticity fly frame system, from spinning frame, carry the bobbin with tail yarn of coming, after entering tail yarn scavenger, because tail yarn rewinds on bobbin, when removing, suction nozzle finds after tail loose thread, due to winding direction with move back rich opposite direction, causing tail loose thread to find is inhaled and is broken, finally can not find tail loose thread, and reduce the success ratio that tail yarn scavenger is removed tail yarn, finally cause the transport efficiency of thickness connection delivery system to reduce.
Summary of the invention
The present invention is the weak point of avoiding above-mentioned prior art to exist, and a kind of take-off device of the tail yarn that rewinds is provided, and makes tail yarn scavenger remove smoothly tail yarn, thereby improves the transport efficiency of thickness connection delivery system.
The technical scheme of the take-off device of a kind of tail yarn that rewinds of the present invention is, comprise the electric machine support being arranged in tail yarn scavenger frame, on described electric machine support, drive motor is installed, the output shaft of described drive motor is connected with seat of reel, on described seat of reel, be placed with bobbin, described electric machine support is provided with a switch bracket, described switch bracket is provided with an approach switch, the sensitive surface of described approach switch is concordant with the top of described bobbin, and described approach switch is connected with the controller of tail yarn scavenger.
The rewind take-off device of tail yarn of the present invention, wherein, the controller of described tail yarn scavenger is controlled the turning to of output shaft of described drive motor.
Compared with prior art, the invention has the beneficial effects as follows:
Before tail yarn scavenger is looked for tail loose thread, by the rewind take-off device of tail yarn of the present invention, tail loose thread can be thrown away, and then make tail yarn scavenger can find smoothly, rapidly tail loose thread.
Accompanying drawing explanation
Fig. 1 is the front tail yarn view of the take-off device unwinding of a kind of tail yarn that rewinds of the present invention;
Fig. 2 is tail yarn view after the take-off device unwinding of a kind of tail yarn that rewinds of the present invention.
In figure: the tail yarn of 1-back-roll, 2-suction nozzle, 3-tail layer, 4-seat of reel, 5-electric machine support, 6-drive motor, 7-switch bracket, 8-approach switch, 9-bobbin, 10-tail yarn scavenger frame, the tail loose thread after 11-unwinding.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, technical solution of the present invention is described in further detail.
As depicted in figs. 1 and 2, the take-off device of a kind of tail yarn that rewinds of the present invention, comprise the electric machine support 5 being arranged in tail yarn scavenger frame 10, on described electric machine support 5, drive motor 6 is installed, the output shaft of described drive motor 6 is connected with seat of reel 4, on described seat of reel 4, be placed with bobbin 9, described seat of reel 4 directly drives it to rotatablely move by drive motor 6, thereby drive, with the bobbin 9 of tail yarn, together does rotating Vortex; Described electric machine support 5 is provided with a switch bracket 7, and described switch bracket 7 is provided with an approach switch 8, and the sensitive surface of described approach switch 8 is concordant with the top of described bobbin 9, and described approach switch 8 is connected with the controller of tail yarn scavenger; The controller of described tail yarn scavenger is controlled the turning to of output shaft of described drive motor 6, and drives bobbin 9 rotations with tail yarn by the seat of reel 4 being connected with output shaft.
The working process of the take-off device of a kind of tail yarn that rewinds of the present invention is, from spinning frame, carry the bobbin 9 with tail yarn of coming, Fig. 1 shows the state of the front tail yarn of unwinding, wherein, the hand of rotation B of bobbin 9 when normal clear tail yarn, the tail loose thread 1 of back-roll is that back-roll is on bobbin 9, and just stick to around tail layer 3 on, bobbin 9 enters into after tail yarn scavenger, approach switch 8 detects this bobbin 9 and is removed, and be put on seat of reel 4, , on seat of reel 4, be placed with bobbin 9, now, approach switch 8 sends gets pipe settling signal to tail yarn scavenger controller, tail yarn scavenger controller sends instruction to drive motor 6, drive motor 6 drives bobbin 9 (pressing the A of hand of rotation shown in Fig. 1) high speed reverse rotation by seat of reel 4, utilize the centnifugal force that rotation produces that the tail loose thread 1 rewinding on bobbin 4 is thrown away, make its just no longer stick to around tail layer 3 on.Fig. 2 illustrates the state of tail yarn after unwinding, after the unwinding of back-roll tail yarn, controller sends instruction to drive motor, bobbin 9 is rotated in the forward by the B of hand of rotation shown in Fig. 2 again, tail loose thread 11 after unwinding is thrown out of, thereby make it by the suction nozzle 2 of tail yarn scavenger smoothly, find rapidly improve the work efficiency of tail yarn scavenger, and further improved the transport efficiency of thickness connection delivery system.
Although invention has been described by reference to the accompanying drawings above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present invention; in the situation that not departing from aim of the present invention, can also make a lot of distortion, within these all belong to protection of the present invention.
