Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example 1:

a novel shifting fork sorting mechanism comprises a shifting fork 1 and a motor 2, as shown in figure 4, the motor 2 is installed on a sorting turnout through an installation plate 7, the motor 2 is a stepping motor, as shown in figure 1, an eccentric wheel 3 is fixed on an output shaft of the motor 2, as shown in figure 2, a pin 31 which is vertically and downwardly arranged is fixed on the lower end face of the eccentric wheel 3, as shown in figure 3, a through hole 11 is formed in the middle of the shifting fork 1, the axis of the through hole is arranged in the vertical direction and matched with the pin 31, the through hole 11 is in a round-corner rectangular shape, and the pin 31 extends into the through hole 11 and can slide in the through hole 11; as shown in fig. 1, the right end of the shift fork 1 is rotatably connected to the sorting fork.

The motor 2 drives the eccentric wheel 3 to rotate in a reciprocating mode, and the pin 31 on the eccentric wheel 3 is matched with the through hole 11 in the middle of the shifting fork 1 to drive the shifting fork 1 to rotate in a reciprocating mode.

As shown in fig. 4, the sorting device further comprises a motor driver 6, the motor driver 6 is installed on a portion, close to the motor 2, of the sorting fork, and the motor driver 6 is electrically connected with the motor 2 through a PLC.

Compared with a closed-loop motor, the closed-loop motor is not as stable and reliable as the open-loop motor, so the motor 2 in the embodiment is the open-loop motor, but the open-loop motor cannot feed back whether the rotation is in place or not, that is, whether the rotation of the shifting fork 1 is in place or not cannot be determined, therefore, as shown in fig. 1, the motor 2 is a double-output-shaft motor 2, a coded disc 4 is coaxially fixed on an output shaft at the upper end of the motor 2, an arc-shaped notch is formed in the coded disc 4, a photoelectric sensor 5 is fixed on the motor 2, the photoelectric sensor 5 comprises a transmitting end and a receiving end, and the transmitting end and the receiving end of the photoelectric sensor 5 are respectively positioned above and below the coded disc 4; in the rotating process of the coded disc 4, the arc-shaped notch can be aligned with the transmitting end and the receiving end of the photoelectric sensor 5.

In the rotating process of the coded disc 4, when one end of the arc-shaped notch is aligned with the photoelectric sensor 5, the receiving end of the photoelectric sensor 5 cannot receive a photoelectric signal sent by the transmitting end, the receiving end of the photoelectric sensor 5 sends a pulse signal to the motor driver 6 through the PLC, and the motor driver 6 converts the pulse signal into angular displacement and drives the motor 2 to rotate forward; in the process, the receiving end of the photoelectric sensor 5 continuously receives the photoelectric signal sent by the transmitting end, and the photoelectric sensor 5 does not act continuously; when the other end of the arc-shaped notch is aligned with the photoelectric sensor 5, the receiving end of the photoelectric sensor 5 receives the photoelectric signal sent by the transmitting end again, the receiving end of the photoelectric sensor 5 sends a reverse pulse signal to the motor driver 6 through the PLC, and the motor driver 6 converts the reverse pulse signal into a reverse angular displacement and drives the motor 2 to rotate reversely; and the reciprocating rotation of the motor 2 with a fixed angle is realized continuously.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
