Detailed description of the invention:
With specific embodiment, the invention will be further described below, sees Fig. 12:
A kind of sewing machine broken string induction installation, the guide bracket 2 passed through including base plate 1, confession suture, guide bracket 2 passes through
The guide post of more than one is connected with base plate 1, for be arrangeding in parallel between guide post.It is set with on the guide bar
Elastic component 3, elastic component 3 typically uses spring.Guide bracket 2 is resiliently supported at above base plate 1 by elastic component 3,
Guide bracket 2 can move up and down along guide post, is provided with, on base plate 1 with guide bracket 2, the detector cooperated,
It is respectively induced, when detector is close at guide bracket 2 or deviates from base plate 1, the signal not breaking or breaking；
When there being suture to pass through from guide bracket 2, suture effect guide bracket 2 makes its compression elastic piece 3 towards base plate 1
Mobile, detector will sense that the signal not broken sends to electricity according to the distance between guide bracket 2 and base plate 1
Control, machine works on；
When broken string after, guide bracket 2 deviates from base plate 1 under the effect of elastic component 3 and moves reset, detector according to
The signal sensing broken string is sent to automatically controlled, by automatically controlled control machine by the distance between guide bracket 2 and base plate 1
Shut down.
Specifically, described detector is Hall element 4 and magnet steel 5, and magnet steel 5 is arranged on guide bracket 2, suddenly
You are fixed on base plate 1 by element 4.Certainly, Hall element 4 can exchange, the most just with the position of magnet steel 5
Being to say that magnet steel 5 is fixed on base plate 1, Hall element 4 is fixed on guide bracket 2.
Magnet steel 5 and the change of the spacing of Hall element 4, by hall sensing principle, produce FM signal,
Thus the presence or absence of basis signal judges broken string or does not breaks.
When there being suture to pass through from guide bracket 2, suture effect guide bracket 2 makes its compression elastic piece 3 towards base plate 1
Mobile, magnet steel 5 diminishes with the spacing of Hall element 4, Hall element 4 inductive magnetic steel 5, produces frequency modulation letter
Number, it is judged that now for not breaking state；
Reset, magnet steel 5 principle Hall element is moved when guide bracket 2 deviates from base plate 1 under the effect of elastic component 3
4, Hall element 4 senses less than magnet steel 5, it is impossible to produce FM signal, it is judged that be now broken string state.
In order to prevent magnet steel 5 from producing displacement, magnet steel 5 is embedded on guide bracket 2 or on base plate 1.
In order to preferably fix Hall element 4, described Hall element 4 is fixed on base plate 1 by mounting seat
Or on guide bracket 2.
In addition to Hall element 4 and magnet steel 5 are as detector, it is also possible to use range sensor.
Easy for installation in order to make, arranging guide post is screw 6, arranges more than one through hole on guide bracket 2
10, screw 6 is screwed onto on base plate 1 through the through hole 10 on guide bracket, and elastic component 3 is sleeved on screw 6,
One end of elastic component 3 holds out against in the upper plane of base plate 1, the other end holds out against on the baseplane of guide bracket 2.
Screw 6 typically uses axial screw.
Specifically, the through hole 10 on described guide bracket 2 is provided with two, and correspondingly screw 6 is provided with two.
Arranging two screws 6 makes guiding more steady.Two screws 6 are for be arrangeding in parallel.
The guide bracket 2 of the present invention takes the shape of the letter U, and including horizontal plate 7 and two risers 8, is provided with on two risers 8
The crossed beam trunking 9 passed through for suture or cable-through hole.
Certainly, guide bracket 2 can also be designed to a flat board, arranges crossed beam trunking at flat board two ends；Or at flat board
Two ends be provided with mast, mast is provided with cable-through hole.Final purpose is, how to make suture from
Pass through on guide bracket 2, by time because the tensioning of suture and then compression elastic piece 3 cause guide bracket 2 towards base plate 1
Mobile.
The present invention can apply the burn out detection of each several part on all sewing machines, is particularly applicable in the inspection of bottom line
In survey, it is wrapped on throwing cam after can effectively preventing from breaking because of bottom line.
The present invention also provides for a kind of sewing machine, including sewing machine as above broken string induction installation.
Above-described embodiment is only one of presently preferred embodiments of the present invention, not limits the present invention's with this
Practical range, therefore: the equivalence change that all shapes under this invention, structure, principle are done, all should
Within being covered by protection scope of the present invention.
