Abstract
The invention discloses a touch power-saving switch for a loom. A switch handball (1) is fixed with two adjacent contacts (2), and a wire through hole (3) runs through the switch handball (1); one end of each of two handball conducting wires (4) is connected with the two contacts (2), while the other end is connected with a first contact (A) and a second contact (B) in an amplifying circuit; an inching switch (5) is connected with a pull rope (8) through a control lever (9), and the other end of the pull rope (8) is connected with a pull rod (7); and the other end of each of two inching switch conducting wires (6), one end of each of which is connected with the inching switch (5), is connected with the first contact (A) and the second contact (B) in the amplifying circuit respectively. Only the hand of an operator touches the switch handball of the loom, a motor is immediately started, and a handle of the switch does not begin to move toward the power-on position at this time. Therefore, the idle load of the motor is ensured to reach the normal rotating speed to avoid sparse marks and shuttle trapping phenomenon.
Description
Technical field the present invention relates to a kind of touching type switch apparatus, particularly a kind of touch power-saving switch device that is used to control loom.
The existing loom battery-conserving switch of background technology has only after switch knob leaves the parking spot certain distance, and motor just begins to start.And switch knob only needs the extremely short time from the parking spot to the service position when driving, thereby often motor does not reach normal rotating speed as yet, and loom just and then rotates, and causes the sparse road fault of fabric easily, even trapped shuttle.
Summary of the invention technical problem to be solved by this invention is, overcomes the defective of above-mentioned existing procucts, and a kind of touch power-saving switch for loom is provided, and avoided sparse road defect and trapped shuttle phenomenon by the motor No Load Start; By eliminating the no-load running of motor, further improve electricity saving performance.
The present invention has adopted following technical scheme.
A kind of touch power-saving switch for loom comprises the switch handball and the microswitch that are installed on the handle, it is characterized in that: be fixed with two mutually adjacent contacts on the switch handball, and the penetrating switch handball offers through wires hole; Article two, handball lead one end connects described two contacts, and the other end connects first contact and second contact in the amplifying circuit respectively; Microswitch is connected with stay cord by control lever, and the other end of stay cord is connected with pull bar; The other end of two microswitch leads of one end connection microswitch connects first contact and second contact in the amplifying circuit respectively.
First contact in the amplifying circuit connects in the handball lead, and receives the positive pole of 6V dc source; Second contact connects another in the handball lead, and connects the base stage of first triode by first resistance; The colelctor electrode of first triode is received the positive pole of 6V dc source by second resistance; The emitter stage of first triode is received the negative pole of 6V dc source through the 3rd resistance, the emitter stage of first triode also connects the base stage of second triode, the positive pole of the colelctor electrode of second triode and 6V dc source connects the coil two ends of sensitive relay respectively, and at backward dioded that shields of described coil two ends parallel connection; Sensitive relay is serially connected with and is used for the A.C. contactor that is connected with motor.
Good effect of the present invention is: (1), as long as operator's hand touch loom switch handball, motor starts immediately, this moment, switch knob did not begin to the service position motion, and this has just guaranteed that the motor zero load reaches normal rotating speed, thereby has avoided sparse road defect and trapped shuttle phenomenon.(2), when loom is shut down, switch knob is in parking spot, pull bar falls; the normally opened contact of microswitch separates, and operator's hand leaves the switch handball, and the normally opened contact of sensitive relay and A.C. contactor separates; the motor dead electricity is shut down, thereby has realized purpose of saving.

The specific embodiment further specifies the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, be installed on two contacts 2 that are fixed with on the switch handball 1 on the handle at a distance of 1 millimeter, and penetrating switch handball 1 offers through wires hole 3.Article two, handball lead 4 one ends connect described two contacts 2, and the other end connects the first contact A point and the second contact B point in the amplifying circuit shown in Figure 3 respectively.
As shown in Figure 2, microswitch 5 of the present invention is connected with stay cord 8 by control lever 9, and the other end of stay cord 8 is connected with pull bar 7.The other end of two microswitch leads 6 of one end connection microswitch 5 connects the first contact A point and the second contact B point in the amplifying circuit shown in Figure 3 respectively.
In the circuit as shown in Figure 3, the first contact A point connects in the handball lead 4 shown in Figure 1, and receives the positive pole of 6V dc source.The second contact B point connects another in the handball lead 4 shown in Figure 1, and by first resistance R
1Connect the first triode BG
1Base stage; The first triode BG
1Colelctor electrode by second resistance R
2Receive the positive pole of 6V dc source; The first triode BG
1Emitter stage through the 3rd resistance R
3Receive the negative pole of 6V dc source, the first triode BG
1Emitter stage also connect the second triode BG
2Base stage, the second triode BG
2Colelctor electrode and the positive pole of 6V dc source meet sensitive relay J respectively
1The coil two ends, and at described coil two ends backward dioded that shields in parallel.
Shown in Fig. 4,5, sensitive relay J
1With A.C. contactor J
2Serial connection, A.C. contactor J
2Connect motor.
The working power of touch power-saving switch circuit is the 6V dc source.The main amplifying circuit of being made up of two transistors uses as on-off circuit.The control signal of circuit is from the switch handball 1 of loom.When operator's hand switch handball 1, hand touches two contacts 2 on the switch handball 1 simultaneously, by handball lead 4 six volts of dc sources are connected, amplifying circuit is promptly in running order, and amplifying circuit amplifies the weak current by staff and makes sensitive relay J
1The normally opened contact closure, also make simultaneously A.C. contactor J
2The normally opened contact closure, thereby started the drawing motor of loom.
Handle at switch handball 1 is pushed in the process of service position, and drawing motor has entered the duty of normal operation, has realized the No Load Start of motor.When the handle of switch handball 1 is pushed to the service position, the normally opened contact of microswitch 5 is in closure state under the control of pull bar 7, and has replaced the electric action of staff, therefore, when the operator finished boot action and leaves switch handball 1, the normal operation of motor was still kept.
During shutdown, the handle of switch handball 1 is in parking spot, the contact separation of microswitch 5, and simultaneously, amplifying circuit loses the signal of telecommunication of switch handball 1, and two transistors are in by state, sensitive relay J
1With A.C. contactor J
2Contact separation, drawing motor quits work.
