When a carrier is transported to the second end by the upper stream line 11, the work pieces in the carrier are removed, and the downward moving device 20 moves the empty carrier from the upper stream line 11 to the lower stream line 12.

Fig. 10-13 are schematic structural views of a conveying device according to an embodiment of the present invention. Referring to fig. 10 to 13, the conveying cylinder 24 includes a first cylinder 241 and a first push rod 242 slidably disposed along the first cylinder 241, the first cylinder 241 is fixedly connected to the fixing plate 21, and the first push rod 242 is connected to the conveying flow line 22. When the conveyance cylinder 24 expands and contracts, the conveyance flow line 22 is driven to move up and down with respect to the fixed plate 21. The carrying cylinder 24 is used for driving the carrying streamline 22 to move up and down between the lower working position and the upper working position so as to drive the carrier to move up and down. Wherein the transfer flowline 22 is aligned with the lower flowline 12 when in the lower operating position to enable transfer of vehicles between the transfer flowline 22 and the lower flowline 12; the transfer flow line 22 is aligned with the upper flow line 11 when in the up position to enable the transfer of vehicles between the transfer flow line 22 and the lower flow line 12.

The transfer flow line 22 employs a belt drive assembly to power movement of the vehicle to the flow device 10. In one embodiment, the transfer flowline 22 comprises a base 221 and first 222 and second 223 transfer flowline units disposed on the base 221. The first transfer flowline unit 222 is secured to the base 221 and comprises a first belt drive assembly. The second transfer flowline unit 223 is spaced apart from and disposed in parallel with the first transfer flowline unit 222, the second transfer flowline unit 223 comprising a second belt drive assembly. The two ends of the carrier are respectively placed on the first belt transmission component and the second belt transmission component. The first belt drive assembly and the second belt drive assembly are configured to move in synchronization, thereby moving the vehicles toward or away from the circulation device 10. The first belt transmission assembly and the second belt transmission assembly can be driven by the same driving device, and can also be driven by two driving devices respectively.

In some embodiments, the handling device 20 further comprises a first position sensor 251 and a second position sensor 252. The first position sensor 251 and the second position sensor 252 are used to detect the position of the carrier on the transfer flow line 22. Alternatively, the first position sensor 251 and the second position sensor 252 may be photoelectric switches. The first position sensor 251 is positioned at an end of the handling flow line 22 proximate to the flow-around device 10 and the second position sensor 252 is positioned at an end of the handling flow line 22 distal from the flow-around device 10. Referring to fig. 14, the first position sensor 251 and the second position sensor 252 are electrically connected to the control circuit 30, respectively, and the control circuit 30 controls the operation of the conveying device 20 based on signals triggered by the first position sensor 251 and the second position sensor 252.

Further, the circulation device 10 further includes a fourth position sensor 171 and a fifth position sensor 172 for detecting the position of the vehicle on the lower layer flow line 12. Alternatively, the fourth position sensor 171 and the fifth position sensor 172 use photoelectric switches. A fourth position sensor 171 and a fifth position sensor 172 are respectively arranged at the two ends of the lower layer streamline 12, and when the carrier moves into the lower layer streamline 12 from the downward conveying device 20 at the second end of the circulation device 10, the fourth position sensor 171 detects the passing of the carrier; the fifth position sensor 172 detects the passage of a vehicle as it moves out of the lower flowline 12 from the first end of the flow-around device 10 into the upstream handling device 20 disposed at the first end. Referring to fig. 14, the control circuit 30 is electrically connected to a fourth position sensor 171 and a fifth position sensor 172.

When the carrier circulation equipment works, when the conveying streamline 22 of the downward conveying device 20 arranged at the second end of the circulation device 10 is at the upper working position, the conveying direction of the conveying streamline 22 is the same as the conveying direction DIR1 of the upper streamline 11, so that the carriers conveyed by the upper streamline 11 can be conveniently received, and the carriers can be prevented from falling off in the process of moving up and down. When the upper stream line 11 transports the carrier to the transport stream line 22 of the down transport device 20, the first position sensor 251 and the second position sensor 252 are sequentially activated, and the control circuit 30 controls the transport cylinder 24 to operate, so that the transport stream line 22 moves from the upper working position to the lower working position. After the carrying streamline 22 moves to the lower working position, the control circuit 30 controls the carrying streamline 22 to rotate reversely, so that the carrying direction of the carrying streamline 22 is the same as the carrying direction DIR2 of the lower layer streamline 12, therefore, the carriers can be carried to the lower layer streamline 12, in the process, the first position sensor 251 and the fourth position sensor 171 are sequentially triggered to indicate that the carriers are moved out of the carrying streamline 22, and the control circuit 30 controls the carrying cylinder 24 to work, so that the carrying streamline 22 moves to the upper working position.

When the carrier moves from the lower streamline 12 to the transfer streamline 22 of the ascending transfer device 20 at the first end of the circulation device 10, the fifth position sensor 172 and the first position sensor 251 and the second position sensor 252 arranged on the ascending transfer device 20 are sequentially triggered, the control circuit 30 controls the transfer cylinder 24 to operate, so that the transfer streamline 22 moves from the lower operating position to the upper operating position, and the carrier is aligned with the upper streamline 11. When the carrier stays at the position, the carrier can be loaded with the workpiece. Then, the control circuit 30 controls the transportation flow line 22 to rotate reversely, so that the transportation direction of the transportation flow line 22 is the same as the transportation direction DIR1 of the upper flow line 11, the carrier removal transportation flow line 22 enters the upper flow line 11, and the second position sensor 252 and the first position sensor 251 are sequentially triggered. When the carrier is completely moved out of the upward conveying device 20, the control circuit 30 controls the conveying cylinder 24 of the upward conveying device 20 to work, so that the conveying flow line 22 moves back to the lower working position again.

In some embodiments, the distance between the first and second transfer flowline units 222, 223 is adjustable. The base 221 is provided with a first slide rail 224, and the first slide rail 224 extends along a direction perpendicular to the flow line 22.
