Description
Technical field
The utility model relates to loom structure design and control technology field, specifically, relates to a kind of braiding machine line-breaking stoppage device.
Background technology
In the braiding machine technical field, the broken yarn in the compilation process, broken string etc. are one of common problems.Broken yarn, broken string problem can not get in time finding and correcting; Usually can cause the product quality defects of producing, cause the rising of defect rate, percent defective, sometimes; Broken yarn, broken string situation the back braiding machine occurs and work on; Can cause the fault of braiding machine, not only cause the generation of substandard products and waste product, also can influence normally carrying out of subsequent production.
Therefore, need design a kind of can be for the automatic device for monitoring of broken string problem.
The patent No. is the novel patent of the use of ZL 97238569.X; Disclose a kind of Soft ribbon circular loom, the Soft ribbon circular loom of this patent also has a simple broken yarn automatic stopping device (referring to Figure of description 1), is made up of upper plate, lower plate and spring; The spring upper end is a carbine; Upper plate, lower plate all are fixed on outside the frame, and carbine passes through on upper plate, and upper plate is connected with electric control system.Establish a contact block on the carbine, under the normal condition, carbine hooks yarn, and contact block does not contact with upper plate, and circular loom normally moves; When broken string took place, spring was left behind carbine, and contact block is run into upper plate, and upper plate is metallic plate and is electrically connected with brake apparatus, just can realize the braking under the broken string state.
But the mechanical braking technology that this technology is exists following problem in the production practices process:
1. the hole of contact block and upper plate is complementary, through using for a long time and rub, the sidewall of contact block and last holes; Will certainly there be the gap, and when excesssive gap, even might cause broken string; Contact block also bumps less than upper plate, like this, just can not effectively connect braking circuit;
2. spring through stretching for a long time, will inevitably cause the coefficient of stiffiness to change under the situation that is not having broken string, promptly shrinks not obviously, might be able to not contact block effectively be retracted;
3. because carbine hooks yarn, in the circular loom running, a tension is arranged for carbine; Just cause by yarn and spur spring to bending on one side through carbine, like this, through stretching for a long time; Spring can produce certain bending in the vertical; Therefore, when contact block is retracted, might contact block be blocked at the upper plate place owing to the bending of spring itself.

The beneficial effect of the utility model is:
1. adopt position sensor to pass through the position of induction pull bar lower end, thereby realize perhaps connecting, compare, have higher reliability with simple machine control unit in the conventional art with the disconnection of braiding machine broken string braking circuit;
2. as preferred embodiment a kind of, adopt guide cylinder to come pull bar and extension spring are carried out motion guide, the change in location that makes position sensor sense is more accurate;
3. preferred embodiment a kind of as in addition, the lower end of pull bar is provided with counterweight, can be when broken string takes place; Secondary spring retracts pull bar, and real with spring is the structural design of dual fail-safe, has guaranteed when the broken string generation; Can be effectively and braking circuit connect, realize stopping;
4. position sensor is electrically connected with electronic alarm, and when realizing the broken string Brake stop, prompting operating personnel that can be very fast in time overhaul machinery equipment, resume production as early as possible.
Description of drawings
Fig. 1 is the line-breaking stoppage apparatus structure sketch map of prior art;
One of structural representation of Fig. 2 the utility model;
Fig. 3 be the utility model structural representation two.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is the line-breaking stoppage apparatus structure sketch map of prior art, and its operation principle is summarized as follows:
Be made up of upper plate 1, lower plate 2 and spring 3, spring 3 upper ends are carbine 4, and upper plate 1, lower plate 2 all are fixed on outside the frame 5, and carbine 4 passes through on upper plate 1, and upper plate 1 is connected with electric control system.Establish a contact block 6 on the carbine 4, under the normal condition, carbine 4 hooks yarn, and contact block 6 does not contact with upper plate 1, and circular loom normally moves; When broken string took place, spring 3 was left behind carbine 4, and contact block 6 is run into upper plate 1, and upper plate is metallic plate and is electrically connected with brake apparatus, just can realize the braking under the broken string state.
