For the purpose of illustration, only the structures described in connection with the present application are illustrated in the drawings.

The feeding system 10 disclosed in at least one embodiment of the present application includes a feeding rail 100 and a detour rail 200.

The feeding track 100 includes a running track 110 and a movable track 120, the running track has a first track section 111 and a second track section 112 arranged at intervals, the movable track has a discharging station 130 thereon, the movable track 120 can be selectively connected with or disconnected from the first track section 111 and the second track section 112, and the detour track 200 is always communicated with the first track section 111 and the second track section 112 to form a main channel. The movable rail 120 forms a discharge channel with a discharge station 130 when communicating with the first rail section 111 and the second rail section 112, the traffic priority level of the discharge channel is higher than the traffic priority level of the main channel, and the movable rail 120 is disconnected from the first rail section 111 and the second rail section 112 when the discharge station 130 performs a discharge operation. In this way, the bypassing rail 200 is set to keep the feeding system 10 in a smooth state regardless of whether the unloading station 130 is performing the unloading operation, thereby greatly improving the feeding efficiency.

In some embodiments, the feed track 100 is an endless track having a loading station 140 and an unloading station 130 spaced apart thereon. The hopper 300 is loaded with material at the loading station 140 and then moved to the discharge station 130 to discharge the material, thereby completing the transportation of the material.

Optionally, the discharge stations 130 are at least two and are spaced apart along the endless track. In particular, in some embodiments, a plurality of production lines are provided, the endless track is disposed above the production lines, and the number of discharge stations 130 corresponds to the number of production lines. After the hopper 300 is loaded with material at the loading station 140, it is moved to the unloading station 130 and unloaded onto the production line for the production activities of the production line.

In some embodiments, the endless track is further provided with a cleaning station 150, and the loading station 140, the unloading station 130 and the cleaning station 150 are spaced along the endless track. After unloading the material at the unloading station 130, the hopper 300 travels to the cleaning station 150 to be cleaned, and then moves to the loading station 140 to be loaded again. This setting is convenient for the used repeatedly of hopper 300, and makes different materials can not pollute each other. In this embodiment, the loading station 140, the four unloading stations 130, and the cleaning station 150 are sequentially spaced along the circular track.

In some embodiments, the feeding system 10 further includes a lifting device, and the movable rail 120 is coupled to the lifting device and is connected to or disconnected from the first rail segment 111 and the second rail segment 112 by the lifting motion of the lifting device. In particular to some embodiments, the lifting device is a hydraulic cylinder. When the hydraulic oil cylinder performs oil injection, the movable rail 120 can be lifted, so that the movable rail 120 is communicated with the first rail section 111 and the second rail section 112; when the hydraulic cylinder unloads oil, the movable rail 120 descends, so that the movable rail 120 is disconnected from the first rail section 111 and the second rail section 112. In other embodiments, the lifting device may also be a cylinder, a motor or other driving device. In some embodiments, the feeding track 100 and the winding track 200 are formed by a first track and a second track arranged in parallel. Correspondingly, the lifting device comprises a first hydraulic oil cylinder and a second hydraulic oil cylinder, the first rail of the movable rail 120 is connected to the first hydraulic oil cylinder in a matching mode, the second rail of the movable rail 120 is connected to the second hydraulic oil cylinder in a matching mode, the first hydraulic oil cylinder and the second hydraulic oil cylinder can synchronously perform lifting movement through a hydraulic oil cylinder synchronous valve, and therefore the normal passing function of the movable rail 120 is guaranteed.

In some embodiments, the feeding system 10 further comprises at least two hoppers 300, each hopper 300 comprises a carrier drum 310 and a traveling mechanism 330, the carrier drum 310 is used for containing the material, and the traveling mechanism 330 is used for driving the carrier drum 310 to move along the feeding track 100 and the circumambulating track 200.

Specifically, in some embodiments, the driving mechanism 330 includes a driving member 331 and a driving member 332, the driving member 332 is connected to the carrier cylinder 310, the driving member 332 has a driving wheel capable of driving along the feeding track 100 and the detour track 200, and the driving member 331 is configured to drive the driving wheel to travel on the feeding track 100 and the detour track 200. Further, the traveling mechanism 330 further includes a traveling follower 333 connected to the carrier cylinder 310, and the traveling follower 333 is provided with a driven wheel capable of traveling along the feeding rail 100 and the detour rail 200. Further, the driving member 332 and the driving follower 333 are respectively located at both sides of the carrier cylinder 310, and the number of the driving member 332 and the driving follower 333 is two. Of course, in other embodiments, the number of the travel driving members 332 and the travel driven members 333 may be more than two or less than two.

In some embodiments, the carrier cylinder 310 is rotatably disposed on the support frame 320. The support frame 320 includes a first support rod 321 and a second support rod 322, wherein a driving member 332 and a driven member 333 are respectively disposed at both ends of the first support rod 321, and a driving member 332 and a driven member 333 are also respectively disposed at both ends of the second support rod 322. This arrangement allows the driving wheel to be rotated by the driving member 331, and then the driven wheel to be rotated, so that the carrying cylinder 310 can move along the feeding rail 100 and the detour rail 200.

In some embodiments, the at least two hoppers include a first hopper and a second hopper, the first hopper enters the discharge passage when the movable rail 120 is in communication with the first rail section 111 and the second rail section 112 and performs a discharging operation at the discharge station 130 when the movable rail 120 is disconnected from the first rail section 111 and the second rail section 112, and the second hopper enters the main passage when the movable rail 120 is disconnected from the first rail section 111 and the second rail section 112. Specifically, in some embodiments, when the first hopper and the second hopper run on the feeding rail 100, the discharging channel is formed when the movable rail 120 is communicated with the first rail section 111 and the second rail section 112, since the movable rail 120 is a linear rail and the detour rail 200 is an arc rail, the first hopper directly runs on the movable rail 120 due to inertia, and performs the discharging operation when the movable rail 120 is disconnected from the first rail section 111 and the second rail section 112. When the movable rail 120 is disconnected from the first rail segment 111 and the second rail segment 112, the second hopper is guided to the detour rail 200 to bypass the first hopper performing the discharging operation at the discharging station 130 of the movable rail 120. Thus, when the first hopper performs the discharging operation at the discharging station 130, the second hopper can bypass the first hopper through the bypass track 200 to continue the subsequent operation without waiting for the completion of the discharging operation of the first hopper, thereby greatly improving the feeding efficiency.

In some embodiments, the hopper 300 further includes a turning mechanism 340, the wall of the carrying cylinder 310 is provided with a loading/unloading port 311 communicating with the inside of the carrying cylinder, and the turning mechanism 340 is configured to drive the carrying cylinder 310 to rotate around the axial direction. Thus, the loading and unloading are facilitated when the loading and unloading port 311 faces upward, and the unloading is facilitated when the loading and unloading port 311 faces downward.

In some embodiments, the support frame 320 includes a first connection block 323 and a second connection block 324, the first connection block 323 is connected to the first support rod 321, and the second connection block 324 is connected to the second support rod 322. The flipping mechanism 340 includes a flipping drive 341, a first flipping bearing 342, and a second flipping bearing 343. One end of the carrying cylinder 310 is rotatably connected to the first connecting block 323 through a first flip bearing 342, the other end of the carrying cylinder 310 is rotatably connected to the second connecting block 324 through a second flip bearing 343, and the flip driving member 341 is configured to drive the first flip bearing 342 and/or the second flip bearing 343 to rotate. The provision of the first and

second flip bearings

342 and 343 facilitates the rotation of the carrier cylinder 310 about the first and second connecting

blocks

323 and 324 and increases the rotational flexibility of the carrier cylinder 310, thereby facilitating the loading and unloading operations.

In some embodiments, the feeding system 10 further comprises an alarm 350 disposed on the hopper 300. The alarm 350 is used for giving an alarm so as to attract the attention of the operator in time and remove obstacles in time.

In some embodiments, the feeding system 10 further comprises a controller electrically connected to the lifting device. The controller means a device capable of implementing a control function, for example, at least one of a computer, a PLC (programmable logic controller), a DDC (digital controller), and a PCB (printed circuit board) board. Specifically, in some embodiments, the specific discharging station 130 to which the first hopper needs to be delivered is determined, and after the first hopper reaches the determined discharging station 130 (for example, by setting a sensor to sense the position of the first hopper), the controller gives an instruction to disconnect the movable rail 120 from the first rail segment 111 and the second rail segment 112 to the lifting device, so that the movable rail 120 descends, the first hopper starts discharging, and the second hopper can bypass the first hopper performing the discharging operation through the bypassing rail 200. After the first hopper finishes discharging, the controller issues an instruction to the lifting device to communicate the movable rail 120 with the first rail section 111 and the second rail section 112, and the first hopper can leave the discharging station 130.

In some embodiments, the controller is also electrically connected to the travel mechanism 330, the flipping mechanism 340, and the alarm 350, respectively.

In the feeding system, the detour rail 200 is in communication with the first rail segment 111 and the second rail segment 112 to form a main passage, and the movable rail 120 is selectively in communication with or disconnected from the first rail segment 111 and the second rail segment 112. When the movable rail 120 is communicated with the first rail section 111 and the second rail section 112, an unloading channel with an unloading station 130 is formed, the passing priority level of the unloading channel is higher than that of the main channel, when the first hopper executes unloading operation at the unloading station 130, the movable rail 120 is disconnected with the first rail section 111 and the second rail section 112, and the second hopper can bypass the first hopper through the main channel to continue subsequent operation without waiting for the completion of the unloading of the first hopper. In this manner, the feed rate of the feed system 10 is greatly increased.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
