Detailed description of the invention
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present invention and effect easily.
Refer to Fig. 1 to Fig. 4.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the present invention can produce and the object that can reach, all should still drop in scope that disclosed technology contents can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
As shown in Figures 1 to 4, the invention provides a kind of safety detection device of sewing-machine foot arm, whether presser bar is put into for the presser feet arm detected on Sewing machines, safety detection device comprises the proximity transducer 4 being arranged on safety detection position, the single piece of described proximity transducer 4 for being used alone, and for spontaneous emission is from receiving type sensor; Described proximity transducer 4 is connected with the master controller of described Sewing machines.The present invention adopts the proximity transducer of induction type proximity transducer or capacitance-type proximity transducer to be used as safety detection device, and its signal detection is accurate, and without the need to the cooperation of magnetic patch etc., is easy to install and use.
As shown in Figures 1 and 2, for an embodiment of the safety detection device of sewing-machine foot arm of the present invention, safety detection position in the present embodiment is specially on the cutting knife holder 3 adjacent with presser feet arm 2, and proximity transducer 4 is fixed on described cutting knife holder 3 by fixing and mounting bracket 1.Proximity transducer in the present embodiment is arranged on cutting knife holder, and it is more fixing than easier to mount.
With the Sewing machines of the safety detection device in the present embodiment, as shown in Figure 1, the entire infrastructure of Sewing machines is not described further at this, only the structure security-related with presser feet arm is described, main finger pressure pin arm 2, presser bar 5 and above-mentioned proximity transducer 4, be fixed on proximity transducer on cutting knife holder 3 to implement to send the signal detecting presser feet arm, whether changed by the signal accepted and judge presser feet arm 2 whether in presser bar 5.The proximity transducer of the present embodiment detects presser feet arm whether in presser bar by being arranged on a side position (as cutting knife holder), determines whether Sewing machines can clean boot.
Be specially: after presser feet arm 2 exits certain distance in presser bar 5, the detection presser feet arm signal that now proximity transducer 4 sends can be responded to less than presser feet arm 2, proximity transducer 4 is from the information received without presser feet arm, proximity transducer 4 so to the master controller of Sewing machines carry one report to the police and out-of-work signal, Sewing machines enters safe condition.When presser feet arm 2 enters in presser bar 5, along with presser feet arm 2 is more and more less with the distance of proximity transducer 4, when presser feet arm 2 is close to proximity transducer 4, now proximity transducer 4 senses presser feet arm 2 in presser bar 5, and carry a signal that can normally work to controller, Sewing machines enters into can normal operating conditions.
The distance of reaction of proximity transducer 4 can regulate, make Sewing machines presser feet arm 2 exit with enter presser bar in function of sewing enter a state be perfectly safe.
Proximity transducer 4 in the present embodiment belongs to the one in photoelectric sensor, and its operation principle is close by how many judgement measured target things of the infrared infrared energy reflected by extraneous obstruct of proximity transducer detecting spontaneous emission or is left.
As shown in Figures 3 and 4, be another embodiment of the safety detection device of sewing-machine foot arm of the present invention, in the present embodiment, safety detection position is specially in presser feet arm 2, and proximity transducer 4 is embedded in presser feet arm 2.For ease of installing and protection proximity transducer, above-mentioned proximity transducer 4 is located in a shell, and shell pincers are located in presser feet arm 2.Inductor connecting line 41 on proximity transducer is connected with the master controller signal of Sewing machines.
With the Sewing machines of the safety detection device in the present embodiment, as shown in Figure 3, the entire infrastructure of Sewing machines is not described further at this, only the structure security-related with presser feet arm is described, the above-mentioned proximity transducer 4 of main finger, presser feet arm 2 and presser bar 5, telescopic foot-pressing bar 6 is provided with in presser bar, and the presser feet spanner 7 that control foot-pressing bar 6 moves up and down, whether proximity transducer on presser feet arm 2 is implemented to send the signal detecting foot-pressing bar 6, changed judge presser feet arm 2 whether in presser bar 5 by the signal accepted.Proximity transducer 4 in the present embodiment for detecting the position of foot-pressing bar 6, for making shifting out in presser bar 5 of presser feet arm 2 safety.
Particularly, the presser bar 5 in Fig. 3, presser feet arm 1 are in normal position, and the proximity transducer 4 be contained in presser feet arm 1 senses foot-pressing bar 5, and sewing function normally works.When presser feet spanner 7 is toward when pressing down, be contained in foot-pressing bar 6 in presser bar 5 and press down along with presser feet spanner 7 and up move, when presser feet spanner 7 is depressed into extreme position, the foot-pressing bar 6 in presser bar 5 rises to peak.Now proximity transducer 4 does not sense foot-pressing bar 5, and proximity transducer 4 sends to master controller the signal that a Sewing machines can not start work, and now presser feet arm 2 just can safe taking out in presser bar 5.When presser feet arm 2 will be put in presser bar 5, first presser feet spanner 7 is toward pressing down, the foot-pressing bar 6 be contained in presser bar 5 up moves, when presser feet arm 2 has just been put in presser bar 5, now proximity transducer 4 does not sense foot-pressing bar 6, and when unclamping presser feet spanner 7, foot-pressing bar 6 gets back to origin-location, now proximity transducer 4 senses the existence of foot-pressing bar 5, and namely proximity transducer sends to master controller the signal that a sewing function normally starts work.
The distance of reaction of proximity transducer 4 can regulate in addition, makes distance of reaction as far as possible less than normal.When presser feet arm 2 is not put in presser bar 5 completely, when foot-pressing bar 6 gets back to home, now also there is a bit of distance between proximity transducer 4 and foot-pressing bar 6, proximity transducer 4 can not sense the existence of foot-pressing bar 6, so Sewing machines normally can not start work.
In sum, the safety detection device of sewing-machine foot arm of the present invention and Sewing machines, adopt the proximity transducer of non-magnetic-type to determine presser feet arm position, its accuracy of detection is high, is easy to install, and uses reliable.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
