Preferably, said preparation work signal is for adopting the signal that optoelectronic switch produced.
Preferably, said driver element connection external power source specifically is to be accomplished by the adhesive of ac contactor coil.
For achieving the above object, a kind of electric sewer according to the invention, said device comprises control module, detecting unit, driver element and sewing machine body at least, wherein;
Detecting unit is connected with control module, detects the preparation work signal and sends control module to;
Control module receives the preparation work signal and connects external power source;
Driver element gets electric back and gets into the no-load running state;
Sewing machine body is connected with driver element, and by driver element drive work.
Preferably, said detecting unit is made up of the optoelectronic switch on the said sewing machine body pedal, optoelectronic switch power supply and relay; Said control module is made up of A.C. contactor; Said driver element is the sewing motor; Wherein, optoelectronic switch, optoelectronic switch power supply and relay connect through circuit, and are connected with A.C. contactor, and A.C. contactor is connected on the connection line of said sewing motor and external power source.
Preferably, said pedal is connected with coupling through link rod, and said coupling is connected with clutch through link rod, and said clutch is connected with the sewing motor, and said clutch is connected with sewing machine body through belt.
Beneficial effect of the present invention is:
The present invention controls the sewing motoring through the corresponding sense state of optoelectronic switch folding with close, avoided the sewing motor with the situation generation that just always is in running status after external power source is communicated with, saved electric energy.
Description of drawings
Fig. 1 is the structure diagram of the said electric sewer of the embodiment of the invention;
Fig. 2 is the energy-saving circuit figure of the said electric sewer of the embodiment of the invention;
Fig. 3 is the work structuring sketch map of the said electric sewer of the embodiment of the invention.
The specific embodiment
Below in conjunction with Figure of description the present invention is done further description.
As shown in Figure 1, the said a kind of electric sewer of the embodiment of the invention, said device comprises control module 1, detecting unit 2, driver element 3 and sewing machine body 4 at least, wherein;
Detecting unit is connected with control module, detects the preparation work signal and sends control module to;
Control module receives the preparation work signal and connects external power source 5;
Driver element gets electric back and gets into the no-load running state;
Sewing machine body is connected with driver element, and by driver element drive work.
The course of work of above-mentioned electric sewer is:
At first detection is to the preparation work signal and transfer the signal to the control module.Said preparation work signal is exactly the signal that the employee opens driver element will use Sewing machines the time.Control module makes driver element and outside power supply connect the entering running status after receiving this signal, and under this state, driver element does not also drive sewing machine body and carries out work.Have only behind the pedal of stepping on down on the sewing machine body, driver element could drive sewing machine body, and then makes Sewing machines work.
In order better the present invention to be understood, the structure in the face of each unit describes down:
As shown in Figure 2, said detecting unit is made up of the optoelectronic switch on the said sewing machine body pedal, optoelectronic switch power supply and relay; Said optoelectronic switch adopts the electric switch that diffuses, and said optoelectronic switch power supply provides optoelectronic switch required electric weight.Said control module is made up of A.C. contactor; Said driver element is the sewing motor; Wherein, optoelectronic switch, optoelectronic switch power supply and relay connect through circuit, and are connected with A.C. contactor, and A.C. contactor is connected on the connection line of said sewing motor and external power source.
Wherein, the used optoelectronic switch of said detecting unit, also available travel switch, floor push etc.As long as can accomplish above-mentioned all kinds of switch closes back ac contactor coil closure the sewing motor is communicated with external power source.
As shown in Figure 3; Said optoelectronic switch 7 is fixed on the base plate of said pedal 6; Said pedal 6 is connected with coupling 8 through link rod 9; Said coupling 8 is connected with clutch 11 through link rod 9, and said clutch 11 is connected with sewing motor 10, and said clutch 10 is connected with sewing machine body 13 through belt 12.
Detailed operation process of the present invention is:
After power switch K was closed in the operative employee pass, the sewing motor was because the contact KM of A.C. contactor is an open mode, so sewing motor does not at this moment rotate.When riding on pedal of operative employee; After optoelectronic switch GK under the pedal is shut out the light by pin, since the power supply of optoelectronic switch power supply G, relay K A adhesive; Normally opened contact KA-1 becomes closure state; The then coil KM adhesive of A.C. contactor, then contact KM becomes closure state, and the sewing motor begins to rotate thereupon.But the rotation of sewing motor is the no-load running state, fails to drive Sewing machines work.After operative employee's pin left pedal, then relay K A separated, and contact KA-1 becomes released state again, and then the coil KM of A.C. contactor separates thereupon, and then contact KM becomes released state again, and the sewing motor no longer rotates.
When the sewing motor was in rotary state, the operative employee firmly trampled pedal, because the effect of coupling, link rod and belt, sewing motor and Sewing machines are in interconnected state, at this moment, and the work of sewing motor drives Sewing machines.
A kind of electric sewer power-saving method may further comprise the steps:
Whether detection exists the preparation work signal;
If there is signal, driver element is connected external power source and is got into the no-load running state;
Otherwise driver element does not move;
Driver element under the no-load running state is connected with sewing machine body, drive sewing machine body work.
Said preparation work signal is for adopting the signal that optoelectronic switch produced.
It specifically is to be accomplished by the adhesive of ac contactor coil that said driver element is connected external power source.
Said driver element is the sewing motor, and the thought of said power-saving method is for working as when the operative employee is idle, and the motor of avoiding sewing is in the no-load running state, the waste electric energy.
More than; Be merely preferred embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
