Detailed implementation mode

[0020] Refer to Figures 1-4 As shown in the figure, the utility model relates to an intelligent conveying system for bulk bags, which includes an overhead conveying line 1, a packing machine 2, a packing machine roller line 3, and a connecting and unpacking roller line 4. The two overhead conveying lines 1 are arranged side by side. There are several trolleys 5 for lifting bulk bags on the overhead conveying line 1. Along the conveying line direction on the ground under each overhead conveying line, there are multiple bag hanging stations and multiple bag unloading stations. The trolley 5 runs along the main track 1.1 of the overhead conveying line 1. The overhead conveying line 1 is provided with a bulk bag translation mechanism 6 corresponding to the bag hanging station. The bag hanging station is provided with a packing machine 2 and a packing machine roller line 3, and the packing machine 2 corresponds to the packing machine roller line 3 one by one. There is at least one switch 7 on the overhead conveying line 1. By controlling the movement of each switch 7, the bulk bag is conveyed to the corresponding bag unloading station. Each overhead conveying line is provided with two bag unloading stations, and the two bag unloading stations are respectively arranged at the diagonals of the stacking area 8 to improve the stacking efficiency. Each bag unloading station is provided with a connecting and unpacking roller line 4. The trolley 5 unloads the bulk bag on the connecting and unpacking roller line 4 through an electric hook release sling 9, and the gantry crane 10 in the stacking area 8 performs the bulk bag lifting and stacking operation.

[0021] The bulk bag translation mechanism 6 includes a translation inner frame 6.1, a translation outer frame 6.2, and a first electric push rod 6.3. The translation outer frame 6.2 is supported by columns. The translation outer frame 6.2 is connected to the translation inner frame 6.1 through the first electric push rod 6.3. The translation inner frame 6.1 is provided with a main connecting beam 6.1.1 and an auxiliary connecting beam 6.1.2 parallel to the main track of the conveying line. When the trolley 5 moves from the main track to the main connecting beam 6.1.1 of the translation inner frame 6.1, the first electric push rod 6.3 pushes the translation inner frame 6.1 to move. The empty trolley reaches the bag hanging station along with the main connecting beam 6.1.1 for bag hanging operation. At the same time, the auxiliary connecting beam 6.1.2 is connected to the main track to ensure the smoothness of the main track loop of the conveying line. After the bag hanging is completed, the first electric push rod 6.3 is pushed in the reverse direction to push the translation inner frame 6.1. The full-load trolley is connected to the main track 1.1 along with the main connecting beam 6.1.1. Through two rail changes, the bulk bag hanging and conveying are realized without affecting the normal conveying of the other trolleys.

[0022] The turnout 7 comprises a turnout outer frame 7.1, a turnout inner frame 7.2 and a second electric push rod 7.3. The turnout outer frame 7.1 is supported by a column. The turnout outer frame 7.1 is connected to the turnout inner frame 7.2 through the second electric push rod 7.3. A turnout entrance 7.1.1 is provided at one end of the turnout outer frame 7.1, and a turnout straight rail exit 7.1.2 and a turnout curved rail exit 7.1.3 are provided at the other end. The turnout inner frame 7.2 is provided with a movable straight rail 7.2.1 and a movable curved rail 7.2.2. The two ends of the movable straight rail 7.2.1 are matched with the turnout entrance 7.1.1 and the turnout straight rail exit 7.1.2 respectively. The two ends of the movable curved rail 7.2.2 are matched with the turnout entrance 7.1.1 and the turnout curved rail exit 7.1.3 respectively. The second electric push rod 7.3 pushes the turnout inner frame 7.2 to move, and connects the corresponding curved rail or straight rail according to the needs of the unloading station.

[0023] Two overhead conveyor lines 1 arranged side by side share a cross-zone translation mechanism 11. The structure of the cross-zone translation mechanism 11 is the same as the ton bag translation mechanism. The movable inner frame is provided with two connecting beams in parallel. When the two overhead conveyor lines 1 are independent of each other, each connecting beam is connected to the main track of the conveyor line on the same side in a one-to-one correspondence; when the two overhead conveyor lines 1 are related to each other, the inner frame is translated and moved, and only one connecting beam is connected to the main track of the conveyor line on the opposite side, thereby realizing the cross-zone between the two overhead conveyor lines.

[0024] Each trolley is equipped with a PLC system, which communicates with the ground dispatching system. The ground dispatching system sends the target operating position and operating information to the trolley PLC, which then operates autonomously and feeds the operating results back to the dispatching system.

[0025] The trolley is equipped with an electric unhooking sling, which adopts a manual hooking and automatic unhooking form.

[0026] The baler drum line is provided with a first sensor. When the first sensor detects a ton bag, it sends a lifting request instruction to the ground dispatching system. The ground dispatching system sends a lifting task to the nearest untask trolley. The trolley reaches the ton bag translation mechanism above the target baler to carry out the ton bag lifting operation. After the ton bag is hooked, the trolley moves back to the main line of the aerial conveyor line. The dispatching system assigns tasks to the trolley, and each switch is connected according to demand to transport the ton bag to the designated unloading station.

[0027] The connecting and unloading bag drum line is provided with a second sensor. When the second sensor determines that there are no ton bags on the connecting and unloading bag drum line, it notifies the trolley that it can unload. If it detects that there are ton bags on the connecting and unloading bag drum line, it notifies the trolley to wait on the aerial conveyor line.

[0028] An auxiliary track 12 is provided between the two aerial conveyor lines 1. When necessary, the two aerial conveyor lines can be connected by manual lane change to transfer the trolley. Embodiment

[0029] The 1# and 2# aerial conveyors are arranged side by side. There are 5 packing machines under the 1# aerial conveyor. The 1# aerial conveyor is equipped with a 1# switch and a 2# switch. The trolley transports the ton bags to the 1# and 2# bag unloading stations in the 1# stacking area. There are 6 packing machines under the 2# aerial conveyor. The 2# aerial conveyor is equipped with a 3# switch and a 4# switch. The trolley transports the ton bags to the 3# and 4# bag unloading stations in the 2# stacking area.

[0030] When the curved rails of the 1# and 2# switches are connected, the trolley transports the ton bags to the 1# bag unloading station in the 1# stacking area. When the straight rails of the 1# and 2# switches are connected, the trolley transports the ton bags to the 1# and 2# bag unloading stations in the 1# stacking area simultaneously.

[0031] When the straight rail of the 3# switch is connected and the curved rail of the 4# switch is connected, the trolley transports the ton bags to the 3# bag unloading station in the 2# stacking area. When the curved rail of the 3# switch is connected and the straight rail of the 4# switch is connected, the trolley transports the ton bags to the 3# and 4# bag unloading stations in the 2# stacking area simultaneously.

[0032] In addition to the above embodiments, the present utility model also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present utility model.
