When a carrier moves forward on a main rail and triggers an interpretation sensor in front of a screening station, a control system judges that the carrier does not need to enter the screening station, and when the carrier needs to enter the screening station, the control system controls an internal circulation main rail 1 to be in butt joint with the main rail so that the carrier enters the internal circulation main rail 1 from the main rail; when it is not necessary to enter the screening station, the vehicle continues to travel directly on the main rail. When the carrier enters the internal circulation main rail 1, the carrier continuously moves forward through the gravity of the carrier, when the carrier moves forward in the internal circulation main rail 1 to trigger the first interpretation sensor, the control system can judge that the carrier does not need to go out of the screening station again, if the carrier needs to go out of the screening station, the movable rail driving part drives the movable rail 4 to contract so that the internal circulation main rail 1 is communicated with the outbound rail 3 and is disconnected with the internal circulation branch rail 2, and the carrier enters the outbound rail 3 from the internal circulation main rail 1 and returns to the main rail from the outbound rail 3; if the screening station does not need to be discharged, the movable rail driving part drives the movable rail 4 to extend out so as to block the internal circulation main rail 1 from the discharging rail 3, the movable rail driving part is connected with the internal circulation branch rail 2, the carrier enters the internal circulation branch rail 2 from the internal circulation main rail 1 and returns to the internal circulation main rail 1 from the internal circulation branch rail 2, and the steps are repeated.
The control method of the internal circulation screening station enables the carrier which does not need to enter the next work station to automatically circulate in the screening station instead of returning to the main rail first and then reentering the screening station from the main rail, effectively reduces unnecessary occupation of main rail resources, avoids carrier congestion and improves the working efficiency of the whole garment hanging system.
The position between the L1 and the L2 further comprises an S1 control system which judges whether the screening station can allow the vehicles to enter through a full loading device arranged on an inner circulation main rail, if so, the screening station enters the L2; otherwise, the carrier continues to advance on the main rail. Whether the number of carriers in the screening station reaches the limit or not can be determined through the full-load detection step, and if the number of carriers reaches the limit, the carriers are not allowed to enter the screening station again, so that the using effect of the screening station is guaranteed.
In the L2, the inner circulation main rail is provided with a first blocking and releasing device 5 which is matched with the first interpretation sensor, and the control system blocks or releases the carrier through the first blocking and releasing device 5 and the first interpretation sensor. The first sensor setting of reading is in first 5 departments of stopping release, makes the effect of reading of carrier better on the one hand, and on the other hand can also stop the carrier for a certain time after the carrier is read and is accomplished, guarantees that activity rail and activity rail driver part have sufficient time to accomplish corresponding action.
In the L2, the inner circulation track is provided with a third barrier release device 6 and a third interpretation sensor, and the control system blocks or releases the vehicle through the third barrier release device 6 and the third interpretation sensor. The third blocking and releasing device 6 is arranged to make the carrier pause first in the descending process and then slowly enter the internal circulation main rail 1, so that the phenomenon that the carrier strongly shakes in the process of entering the internal circulation main rail 1 from the internal circulation branch rail 2 is avoided, in addition, the time for the carrier to enter the internal circulation main rail 1 can be controlled through the arrangement of the third interpretation sensor, and the carrier is prevented from just passing through the corresponding position when the carrier enters the internal circulation main rail 1.
In the L3, the outbound rail is provided with a four-bar barrier release device 7 and a fourth interpretation sensor, and the control system blocks or releases the vehicle by the four-bar barrier release device 7 and the fourth interpretation sensor. The fourth blocking and releasing device 7 can make the carrier pause first in the descending process and then slowly enter the main rail, so that the phenomenon that the carrier strongly shakes in the process of entering the main rail from the outbound rail 3 is avoided, in addition, the setting of the fourth interpretation sensor can control the opportunity of entering the main rail by the carrier, and the condition that the carrier just passes through the corresponding position when the carrier enters the main rail is avoided.
