Description

A kind of warping machine with warp break autoalarm

Technical field

The utility model relates to a kind of warping machine field, and more particularly, it relates to a kind of warping machine with warp break autoalarm.

Background technology

Warping process is that textile industry is knitted one of important procedure of front preparation, in warping process, the warp thread that bobbin is drawn on bobbin cradle, first through the gap process broken end detector between yarn gripper and column, forward through guide porcelain plate, again through thread-carrier rod, through yarn sley, be wound up in warp beam after walking around measuring roller. Warp beam can be directly dragged to by variable-speed motor. When winding diameter increases, sent the signal of velocity variations by the tachometer generator being connected with measuring roller, automatically reduce the rotating speed of motor through electrical control gear, to keep warp beam convoluting speed constant. According to the difference of the thickness of organizine or tensile strength, the tension force needing when warping is also different.

But in warping process, often not avoid, warp thread self easily produces the odjective causes such as static, inhomogeneous through line tension, warp beam convoluting speed is non-constant, causes warp break, greatly reduces the quality of warp thread, the performance of enterprises and prestige are had a greatly reduced quality.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of warping machine with warp break autoalarm simple in structure.

For achieving the above object, the utility model provides following technical scheme.

A kind of warping machine with warp break autoalarm, comprise frame, be arranged at the yarn sley in frame, warp beam, horizontal direction between described yarn sley and warp beam is provided with autoalarm, autoalarm have one with the stress surface of warp thread close contact, autoalarm comprises:

Detection module, the pressure size while being subject to warp thread compressing for detection of described stress surface, and export corresponding pressurized signal;

Comparison module, by by pressurized signal and reference signal comparison, and exports corresponding triggering signal according to comparative result;

Alarm module, sends corresponding alarm signal in response to described triggering signal.

By above technical scheme, in the time of warping machine warping, detection module is arranged on support and with yarn sley, warp at grade. If from yarn sley warp break out, the warp thread of fracture does not produce and exerts pressure stress surface, and detection module, according to the signal detecting, produces pressurized signal, exports triggering signal by comparison module, and alarm module sends alarm signal according to corresponding triggering signal

Further, autoalarm comprises support, is fixed on the horizon bar on support, the upper surface that described stress surface is horizon bar.

Further, detection module comprises some pressure sensors that are arranged at horizon bar upper surface, and some described pressure sensors are along the length direction continuous arrangement of horizon bar.

Further, comparison module comprises:

Reference circuit, for providing described reference signal;

Comparator, for by pressurized signal and reference signal comparison, its in-phase end is inputted described reference signal, end of oppisite phase input pressurized signal, and export corresponding triggering signal according to comparative result.

Further, reference circuit comprises the first resistance and second resistance of series connection; Another termination supply voltage of the first resistance, the other end ground connection of the second resistance.

Further, alarm module comprises PMOS pipe, buzzer; The G level contact of PMOS pipe is signaled, D utmost point ground connection, and the S utmost point connects buzzer one end, an other termination power of buzzer.

Compared with prior art, the utility model has the advantages that: in the time that warping machine occurs cracked ends in warping process, checkout gear by warning device detects, output pressurized signal, export triggering signal by comparison module, alarm module sends alarm signal, the effect of automatic alarm while having reached cracked ends according to corresponding triggering signal.

Detailed description of the invention

See figures.1.and.2 the utility model is described further.

As depicted in figs. 1 and 2, a kind of warping machine with warp break autoalarm, comprise frame 1, be arranged at the yarn sley 6 in frame 1, warp beam 4, horizontal direction between described yarn sley 6 and warp beam 4 is provided with autoalarm, autoalarm comprises detection module 100, comparison module 200, alarm module 300, support 5 and be fixed on the horizon bar 3 on support 5, the upper surface of horizon bar 3 and warp thread close contact. Detection module 100 output pressure signals, export triggering signal by comparison module 200, and alarm module 300 receives triggering signal output alarm signal.

Detection module 100 comprises some pressure sensors 2 that are arranged at horizon bar 3 upper surfaces, and some described pressure sensors 2 are along the length direction continuous arrangement of horizon bar 3. Continuous overburden pressure sensor 2 on stress surface like this, the yarn separating from yarn sley 6 produces pressure to pressure sensor 2, and corresponding detection module 100 detects pressurized signal.

Comparison module 200 comprises reference circuit 210 and comparator 220. Wherein, reference circuit 210 comprises R9 resistance and the R10 resistance of series connection; Another termination voltage of resistance R 9, the other end ground connection of R10 resistance.
