A rail transfer mechanism 6 is arranged between the main rail 1 and the branch rail 2, and can connect or disconnect the main rail 1 and the branch rail 2. And a driver detection device 7 is arranged on the outer side of the transmission chain 3 along the running direction of the carrier 5 and behind the track transfer mechanism 6.
The encoder 11 is mounted in engagement with the drive chain 3 (and may also be integrally mounted in the motor). When the drive chain 3 travels a fixed distance L, the encoder 11 feeds back a pulse message to vectorize the distance traveled by the drive chain 3. The drivers 4 on the transmission chain 3 are counted and numbered by the controller 12, and the specific implementation mode is as follows: an origin is arranged on the transmission chain 3, the driver detection device 7 can detect the origin and the driver 4 and upload signals to the controller 12, and the controller 12 accumulates the numbers of the drivers after the origin from 1. Or setting the origin driver as the No. 1 driver, and accumulating numbers from the origin driver. The controller 12 binds the information (including the identification tag ID of the carrier, such as the radio frequency tag and the two-dimensional code) of the carrier 5 driven by the driver 4 with the driver number, and when the driver detection device detects the driver, the driver number is uploaded to the controller, and the controller determines whether the carrier is bound to the driver according to the driver number, and if the carrier is bound, determines whether the carrier needs to enter the branch track.

The outside of the track transfer mechanism 6 is provided with a track transfer mechanism detection device 10.
The first vehicle detection device 8, the second vehicle detection device 9, and the track-changing mechanism detection device 10 have 6 combinations, as shown in the following table.

The motor, the track transfer mechanism 6, the track transfer mechanism detection device 10, the encoder 11, the driver detection device 7, the first carrier detection device 8 and the second carrier detection device 9 are all connected with the controller 12. The controller 12 may be a PLC, a PC, or an industrial tablet.
The control method comprises the following steps:
1. when the driver detection device 7 detects one driver 4, it uploads a signal to the controller 12, and the controller 12 determines whether the carrier 5 driven by the driver 4 needs to enter the track 2.
2. If the branch rail needs to enter, the controller 12 enables the rail-changing mechanism 6 to act after a certain pulse number N1, so that the branch rail 2 is communicated with the main rail 1; after a certain number of pulses N2 (enough carriers to enter the track), the track switching mechanism 6 is reset.
The pulse numbers N1, N2 are counted from the time when the driver detection means 7 detects the driver 4. N1 is less than the number of pulses required from the driver detection device 7 to the track transfer mechanism 6, for example, 20 pulses are required from the driver detection device 7 to the track transfer mechanism 6, so the track transfer mechanism 6 is normally operated between 1 and 19. N2 is greater than the number of pulses required from the driver detection device 7 to the track transfer mechanism 6 and less than the number of pulses from the driver detection device 7 to the first vehicle detection device 8.
3. Whether the carrier 5 enters the branch rail 2 or not is detected, if the carrier does not enter the branch rail 2, the controller 12 controls the motor of the conveying line to stop running and gives an alarm, and after the carrier which does not enter the branch rail is manually processed, the motor is started.
The following detection methods for detecting whether the carrier 5 enters the branch rail 2 in step 3 are available:
A. the track transfer mechanism detection device 10, the first carrier detection device 8 and the second carrier detection device 9 are used in cooperation. The track transfer mechanism detection device 10 does not detect a signal; or the first vehicle detection device 8 detects the information after a certain time or pulse number after the track transfer mechanism detection device 10 detects the information; or the second carrier detection device 9 does not detect the information after a certain time or pulse number passes after the track transfer mechanism detection device 10 detects the information; all of the above three cases determine that the vehicle 5 does not enter the branch rail 2. The predetermined time or pulse number here refers to the time or pulse number required for the vehicle to run to the first vehicle detecting device 8 or the second vehicle detecting device 9, which is counted from the detection of the signal by the track-changing mechanism detecting device 10.
B. The track transfer mechanism detection device 10 and the first carrier detection device 8 are used in cooperation. The track transfer mechanism detection device 10 does not detect a signal; or the first carrier detection device detects the information after a certain time or pulse number after the track transfer mechanism detection device detects the information; both of the above two cases determine that the carrier does not enter the branch rail.
C. The track transfer mechanism detection device 10 and the second carrier detection device 9 are used in cooperation. The track transfer mechanism detection device 10 does not detect a signal; or the second carrier detection device does not detect the information after a certain time or pulse number passes after the track transfer mechanism detection device detects the information; both of the above two cases determine that the carrier does not enter the branch rail.
D. The first carrier detection device 8 and the second carrier detection device 9 are used in cooperation. The first carrier detection device 8 detects information after a certain time or pulse number since the driver detection device 7 detects that the driver 4 starts counting or the track transfer mechanism 6 starts counting; or the driver detection device 7 detects that the driver 4 starts counting or the track transfer mechanism 6 starts counting, and the second carrier detection device 9 does not detect information after a certain time or pulse number; both of the above cases determine that the vehicle 5 does not enter the branch rail 2. If the driver 4 is detected by the driver detecting device 7, the certain time or number of pulses is larger than the time or number of pulses required for the vehicle to travel from the driver detecting device 7 to the first vehicle detecting device 8 or the second vehicle detecting device 9.
E. Only the first vehicle detection device 8 is installed. When the driver detection device 7 detects that the driver 4 starts counting or the track transfer mechanism 6 starts counting, the first carrier detection device 8 detects information after a certain time or pulse number, and determines that the carrier does not enter the branch track.
F. Only the second carrier detection device 9 is installed. When the driver detection device 7 detects that the driver 4 starts counting or the track transfer mechanism 6 starts counting, the second carrier detection device 9 does not detect information after a certain time or pulse number, and determines that the carrier does not enter the branch track.
In this embodiment, the carrier detection device can detect whether there is a carrier on the driver, and can also detect the tag ID on the carrier according to the actual requirement, and the carrier detection device is the carrier identification device.
The above examples are only preferred embodiments of the present invention, it should be noted that: it will be apparent to those skilled in the art that various modifications and equivalents can be made without departing from the spirit of the invention, and it is intended that all such modifications and equivalents fall within the scope of the invention as defined in the claims.
