Summary of the invention
It is an object of the invention to provide a kind of be not likely to produce wrong report prevent false alarm device.
The technical scheme is that and prevent false alarm device, be placed on the head of Computerized flat knitting machine and use, be mainly made up of probe 1, induction apparatus 2, probe base 3, fixing seat 4 and induction apparatus seat 5, induction apparatus 2 is fixed on induction apparatus seat 5, induction apparatus seat 5 is placed in the side of fixing seat 4 again, induction apparatus 2 is made to be positioned at the top of fixing seat 4, again probe base 3 is fixed to fixing seat 4 from the opposite side of fixing seat 4, probe base top is provided with probe aperture, probe is screwed in probe base top by screw from the top down, the tip making probe is unsettled in fixing seat front, prevent false alarm device from also including two springs 6, the two ends of two springs are separately fixed on overhanging portion and the induction apparatus seat of probe, two springs are made to lay respectively at the both sides, axis of probe, during work, when induction apparatus 2 detects that probe 1 leaves knitting zone, signal is returned to serving server by induction apparatus 2, serving server stops the duty of detection probe 1, after induction apparatus 2 detects that probe 1 returns to knitting zone, signal is returned to serving server by induction apparatus 2, and serving server starts the monitoring to probe 1.
Overhanging portion at probe 1 is provided with two holes, location 11 arranged side by side, accordingly, is respectively arranged on the left side and the right side a fixing hole 51 at induction apparatus seat 5, and the two ends of spring are separately fixed on the hole, location 11 and fixing hole 51 that are positioned at probe axis homonymy.
Described induction apparatus seat 5 includes superposed positioning seat 52, and is positioned at the fixed block 53 below positioning seat 52, and induction apparatus seat is fixed on fixing seat 4 by fixed block 53, makes induction apparatus 2 and positioning seat 52 be positioned at the top of fixing seat 4.
Beneficial effect
1, arrange spring to be coupled together by fixing to the overhanging portion of probe and induction apparatus seat in probe both sides, utilize the pulling force effect of spring, make probe be in the position of relative equilibrium, not easily because unrelated External Force Acting produces wrong report;
2, when probe leaves knitting zone, serving server masks the warning function preventing false alarm device, only when probe is in knitting zone, just recovers to prevent the warning function of false alarm device.
Detailed description of the invention
As depicted in figs. 1 and 2, it is prevented that false alarm device, being placed on the head of Computerized flat knitting machine and use, it is mainly made up of probe 1, induction apparatus 2, probe base 3, fixing seat 4 and induction apparatus seat 5.
Induction apparatus 2 is fixed on induction apparatus seat 5, induction apparatus seat 5 is placed in the side of fixing seat 4 again, induction apparatus 2 is made to be positioned at the top of fixing seat 4, again probe base 3 is fixed to fixing seat 4 from the opposite side of fixing seat 4, probe base top is provided with probe aperture, by screw, probe is screwed in probe base top from the top down, and the tip making probe is unsettled in fixing seat front.
Prevent false alarm device from also including two springs 6, the two ends of two springs are separately fixed on overhanging portion and the induction apparatus seat of probe, make two springs lay respectively at the both sides, axis of probe. Utilize the pulling force effect of spring, make probe be in the position of relative equilibrium, not easily because unrelated External Force Acting produces wrong report.
Overhanging portion at probe 1 is provided with two holes, location 11 arranged side by side, accordingly, is respectively arranged on the left side and the right side a fixing hole 51 at induction apparatus seat 5, and the two ends of spring are separately fixed on the hole, location 11 and fixing hole 51 that are positioned at probe axis homonymy.
The two ends of spring 6 are provided with location hook, just can fix spring by the location hook of both ends of the spring being suspended to respectively on corresponding hole 11, location and fixing hole 51.
Fixing hole 51 is poroid except being arranged to, additionally it is possible to be arranged to hook, projection, is suspended on it by spring location hook also to be able to play the effect of fixing spring.
As it is shown on figure 3, described induction apparatus seat 5 includes superposed positioning seat 52, and being positioned at the fixed block 53 below positioning seat 52, induction apparatus seat is fixed on fixing seat 4 by fixed block 53, makes induction apparatus 2 and positioning seat 52 be positioned at the top of fixing seat 4.
During work, when probe leaves knitting zone, serving server turns off the warning function preventing false alarm device, only when probe is in knitting zone, just starts the warning function preventing false alarm device.
Namely when induction apparatus 2 detects that probe 1 leaves knitting zone, signal is returned to serving server by induction apparatus 2, serving server stops the duty of detection probe 1, after induction apparatus 2 detects that probe 1 returns to knitting zone, signal is returned to serving server by induction apparatus 2, and serving server starts the monitoring to probe 1.
The present invention utilizes the balanced capacity of spring dexterously; probe is enable relatively to remain stable for; when probe is subject to swinging up and down about some little interference appearance; if problem is not seriously not reaching to the degree needing to shut down; the pulling force of spring can be automatically adjusted the position of probe; it is made to automatically revert to correct position, thus avoiding wrong report.
When probe leaves knitting zone, system turns off the warning function preventing false alarm device, only when probe is in knitting zone, restarts its warning function. The present invention can be greatly decreased wrong report, improves work efficiency.
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, and those skilled in the art in the essential scope of the present invention, make a variety of changes or substitute, also should belong to the protection category of the present invention.
