Abstract
An electrical control system for an edge detecting device of a tentering setting machine comprises an ultrasonic sensor, a special controller, a frequency converter or a servo controller and an actuator. The ultrasonic sensor sends out continuous signals of-U to + U according to the position of the selvedge shielding part, the special controller converts and outputs the signals of the ultrasonic sensor to control the speed and the forward and reverse rotation of the frequency converter or the servo controller, and finally the selvedge is ensured on the cloth feeding chain through the actuator. The utility model has the advantages that the transmission of the ultrasonic wave is not interfered by any other conditions, namely the position of the selvedge can be accurately detected regardless of the color of the cloth, the variety of the cloth and the influence of surrounding light rays, thereby achieving the purpose of accurately controlling the selvedge on the cloth feeding chain.
Description
Technical Field
The utility model relates to tentering setting machine equipment in the textile after-finishing industry, in particular to an electrical control system for an edge detection device of a tentering setting machine.
Background
The existing edge detecting devices of the tentering setting machine have two types, one type is infrared ray emission and infrared ray reception, and because the absorption of light by the cloth with different colors is different, the edge detecting device of the second type is generated later, the edge detecting device adopts infrared ray emission, and the high-precision CCD chip receives and transmits signals, so that the detection effect is improved, but the edge detecting device is still influenced by the environment and the color of the cloth. A good control effect cannot be achieved.
Disclosure of Invention
The utility model aims to: the present invention provides an electrical control system for an edge-detecting device of a tenter setting machine, so as to overcome the above technical problems in the prior art.
The technical scheme of the utility model is as follows: it is composed of ultrasonic sensor, special controller, frequency converter or servo controller and executor. The ultrasonic sensor sends out continuous signals of-U to + U according to the position of the selvedge shielding part, the special controller converts and outputs the signals of the ultrasonic sensor to control the speed and the forward and reverse rotation of the frequency converter or the servo controller, and finally the selvedge is ensured on the cloth feeding chain through the actuator.
Preferably, the ultrasonic sensors are reflection type ultrasonic sensors and are arranged at the upper and lower positions of the selvedge, and the calculated values are input to the special controller after signals detected by the two ultrasonic sensors are averaged, so that the detection accuracy of the ultrasonic sensors can be improved.
Preferably, the output signal interval of the special controller can be provided with a dead zone, the dead zone corresponds to the allowable deviation of the selvedge position, and the actuator does not have any action within the range of the dead zone, so that the frequent action of the actuator is avoided, and the service life of the actuator is prolonged.
The utility model has the beneficial effects that: the ultrasonic sensor is adopted, the transmission of ultrasonic waves is not interfered by any other conditions, namely the position of the selvedge can be accurately detected regardless of the color of the cloth, the variety of the cloth and the influence of surrounding light, and the selvedge is accurately controlled on the cloth feeding chain.
