Abstract
The utility model discloses a control system for a rapier loom host and in a low speed weft finding-up, belonging to the textile machinery technology field, which includes a programmable logic controller. A beam button, an inverter, a main clutch and a brake driver board are respectively connected with the programmable logic controller, a main motor is connected with the inverter, the main motor is connected with the main clutch and a braker through a main motor belt, the main clutch and the braker are connected with the main clutch and the brake driver board. By using the control system of the utility model, a forward and reverse turning control contactor, a low speed motor, a low speed clutch and the brake driver board, as well as the low speed clutch and the braker of the original low speed machine are decreased, thereby decreasing the electric control elements, meanwhile the inverter can realize a wide range speed regulation, the speed can be regulated flexibly according to the fabric; the motor output torque can be adjusted according to the load, so the motor self energy loss can be decreased, and the whole machine benefit is increased.
Description
Technical field
The utility model relates to the control system that a kind of Rapier looms main frame and slow train are looked for latitude, specifically is meant the improvement of looking for the machinery and the electric-control system of latitude at Rapier looms host computer control and slow train, belongs to technical field of textile machine.
Background technology
The host computer control of present domestic Rapier looms and slow train look for the machinery of latitude and electric-control system mainly by main motor, main clutch and brake, the drive plate of main clutch and brake, the slow train motor, the slow train chain drive, slow train clutch and brake, the drive plate of slow train clutch and brake is formed, its electrical control and mechanical structure such as Fig. 1, shown in Figure 2, number in the figure: 1-Programmable Logic Controller (PLC), 2-crossbeam button, 3-main motor contactor, 4-main motor, 5-main clutch and brake drive plate, 6-main clutch and brake, 7-slow train rotating control contactor, 8-slow train motor, 9-slow train clutch and brake drive plate, 10-slow train clutch and brake, 11-slow train motor and sprocket wheel, 12-chain, 13-slow train clutch and braking mechanism, 14-main motor belt, the problem that exists in the above-mentioned control system is as follows:
1, the main motor of Rapier looms must be always to run up most when slow train and parking, and speed of a motor vehicle adjustment has only by the belt pulley adjustment, and adjusting range is little; Wait a moment the position of car clutch and brake by controlling near switch, adjust inconvenient, the fault rate height.
2, the rotating in the slow train control system is controlled by contactor, and contactor fault rate height is unfavorable for the protection motor;
3, main motor directly starts by main contactor, and is big for the bearing loss of motor.
The utility model content
Be to solve the defective of prior art, the control system that the purpose of this utility model is to provide a kind of simple in structure, easy to adjust, Rapier looms main frame that fault rate is low and slow train to look for latitude.
The technical scheme that the utility model is taked for achieving the above object is, the control system that a kind of Rapier looms main frame and slow train are looked for latitude, the utility model comprises Programmable Logic Controller (PLC), crossbeam button, frequency converter, main clutch and brake drive plate link to each other with Programmable Logic Controller (PLC) respectively, main motor links to each other with frequency converter, main motor links to each other with brake with main clutch by main motor belt, and main clutch links to each other with the brake drive plate with main clutch with brake.
The beneficial effects of the utility model are as follows:
1, adopts control system of the present utility model, reduced original slow train rotating control contactor, slow train motor, slow train clutch and brake drive plate and slow train clutch and brake, thereby reduced electric controling element; In addition, the utility model changes main motor contactor into frequency converter, and frequency converter can be realized the soft start of motor according to the signal of Programmable Logic Controller PLC, and braking fast during parking stops motor, the convenient rotating at a slow speed that realizes motor during slow train realizes the slow train of loom and looks for the latitude function; Frequency converter can be realized wide-range-timing simultaneously, can adjust motor according to load and exert oneself according to the fabric flexible modulation speed of a motor vehicle, reduces the motor own loss, has effectively protected motor, and energy savings improves the complete machine benefit.
2, cancelled the slow train mechanism that slow train motor and sprocket wheel, chain, slow train clutch and braking mechanism etc. are formed, thoroughly solved the high problem of slow train mechanism-trouble rate, realized main motor in the dead ship condition dormancy, the idling rating low-speed running has been saved the energy; Can reach the debugging scope of 100:1 by frequency converter, and easy to adjust.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

The specific embodiment
As shown in Figure 4, the utility model comprises Programmable Logic Controller (PLC) 31, crossbeam button 32, frequency converter 33, main clutch and brake drive plate 35 link to each other with Programmable Logic Controller (PLC) 31 respectively, main motor 34 links to each other with frequency converter 33, and main clutch links to each other with brake drive plate 35 with main clutch with brake 36.
Adopt control system of the present utility model, reduced original slow train rotating control contactor, slow train motor, slow train clutch and brake drive plate and slow train clutch and brake, thereby reduced electric controling element; In addition, the utility model changes main motor contactor into frequency converter, and frequency converter can be realized the soft start of motor according to the signal of Programmable Logic Controller PLC, and braking fast during parking stops motor, the convenient rotating at a slow speed that realizes motor during slow train realizes the slow train of loom and looks for the latitude function; Frequency converter can be realized wide-range-timing simultaneously, can adjust motor according to load and exert oneself according to the fabric flexible modulation speed of a motor vehicle, reduces the motor own loss, has effectively protected motor, and energy savings improves the complete machine benefit.
In conjunction with shown in Figure 3, main motor 34 links to each other with brake 36 with main clutch by main motor belt 37, compare with original technology, cancelled the slow train mechanism that slow train motor and sprocket wheel, chain, slow train clutch and braking mechanism etc. are formed, thoroughly solved the high problem of slow train mechanism-trouble rate, realize main motor in the dead ship condition dormancy, the idling rating low-speed running has been saved the energy; Can reach 100: 1 debugging scope by frequency converter, and easy to adjust.
