Railless door machine photoelectric induction type electronic journey controller structure

Abstract

The present invention discloses railless doors machine photoelectric induction type electric stroke controller structure, includes an engine base body embedded with an electrical machine, the engine base body also equipped with circuit board that can control electrical machine working, and the circuit board is configured to photoelectricity coupler; the motor drive is connected with a signal wheel which is installed on the engine base body and embedded with at least two photic holes, and the rotating signal wheel produces light signal which can be received by the photoelectric coupler; the rotating signal wheel has several photic holes, use the light signal processing valid data reading, and has simple structure and maintenance convenient; the receive rate of the photoelectric coupler is higher than that of the light signal generated by the signal wheel, and both of the sensitive motion and the whole effect of the photoelectric coupler are better; at the same time the transference rotating motion force is from electrical machine self, is driven by wheel gear middle transference, and has compact structure and a high-availability of the machine.

Description

technical field [0001] The invention relates to the technical field of a stroke controller in a trackless door machine, in particular to a photoelectric induction electronic stroke controller structure of a trackless door machine. Background technique [0002] At present, the operation of the door machine mostly adopts a stroke controller, generally a mechanical stroke controller, and a magnetic counting device can also be used for advanced configurations, such as the Chinese utility model patent "Trackless" with the patent number ZL200520109078.3 Retractable door opener" (announcement number is CN2797567Y) is exactly this kind of design; It comprises DC motor, output shaft, casing, protective shell, worm screw, worm gear, storage battery, base plate, and DC motor, output shaft are installed on the protective shell, and output The sprocket and clutch device are installed on the shaft, and the chain tensioning device is installed under the sprocket, which is fixed on the prot...

[0002] At present, the operation of the door machine mostly adopts a stroke controller, generally a mechanical stroke controller, and a magnetic counting device can also be used for advanced configurations, such as the Chinese utility model patent "Trackless" with the patent number ZL200520109078.3 Retractable door opener" (announcement number is CN2797567Y) is exactly this kind of design; It comprises DC motor, output shaft, casing, protective shell, worm screw, worm gear, storage battery, base plate, and DC motor, output shaft are installed on the protective shell, and output The sprocket and clutch device are installed on the shaft, and the chain tensioning device is installed under the sprocket, which is fixed on the protective shell, and electromagnetic inductors are installed under the two ends of the bottom plate in the direction of movement, and the magnetic sensors installed on the ground The stroke control mode improves the accuracy of the door machine operation to a certain extent, but the magnetism of the magnetic body is easy to diffuse, and the signal reception is easily invalidated by external interference, so there is still an unpredictable stroke out of control phenomenon. A good model adopts the structure of photoelectric induction. This mode is basically free from external interference, the reading of signal data is more accurate, and it has better stability. How to develop a photoelectric induction travel that is more suitable for door operators? Controller is an urgent need of people
