Description

Technical Field

[0001] This utility model relates to a ton bag packaging machine that uses AGV to simultaneously transport full bags and supply pallets, belonging to the field of packaging machinery. Background Technology

[0002] A typical ton bag packaging unit usually includes a pallet feeding device and a full bag output device. An empty pallet typically weighs about 20kg and is about 150mm high, while a full bag can weigh up to 1000kg and be up to 2m high. Therefore, ton bag packaging units require a large space. In cases where space is limited, the pallet feeding device and full bag output device can be eliminated, leaving only the ton bag packaging machine. In this case, a forklift is needed to move the pallet to the packaging position, and after the ton bag packaging machine completes the packaging, the forklift will remove the full bag from the line. Since both pallet feeding and full bag removal are done manually with a forklift, it takes a long time, resulting in low production efficiency of the ton bag packaging machine. There is also the problem of damage to the packaging unit due to human forklift operator error, and there is also a safety risk of injury to personnel working simultaneously with forklift operators and packaging machine operators. Utility Model Content

[0003] To safely and efficiently complete the ton bag packaging process under limited space conditions, this utility model proposes a ton bag packaging machine that uses AGVs to simultaneously transport full bags and supply pallets. It includes a ton bag filling machine, with a lifting conveyor located below the ton bag filling machine. The output end of the lifting conveyor can be connected to a double-layer AGV trolley. The double-layer AGV trolley includes a lower pallet conveyor and an upper pallet conveyor. The lower pallet conveyor can be connected to an external pallet sorting machine to input pallets. When the lifting conveyor is in the lower position, it can be connected to the lower pallet conveyor and transport the pallets to the lifting conveyor. When the lifting conveyor is in the upper position, it can transport full bags and pallets to the upper pallet conveyor connected to it.

[0004] The lifting conveyor includes a frame, with a roller conveyor in the middle and a scissor lifting mechanism at the lower end. The upper part of the scissor lifting mechanism is hinged to the cylinder rod of a lifting cylinder, and the cylinder body of the lifting cylinder is hinged to the frame. The lifting cylinder drives the roller conveyor to move vertically. At the front and rear ends below the longitudinal beam of the roller conveyor, there are horizontally arranged overlapping beams. The overlapping beams are hinged to the cylinder rod of a translation cylinder, and the cylinder body of the translation cylinder is hinged to the roller conveyor. When the overlapping beams are in the initial position, they are located on the outside of the frame. When the roller conveyor is in the upper position, the translation cylinder can drive the overlapping beams to move horizontally back and forth. At this time, the overlapping beams can overlap the upper end of the support beam of the frame.

[0005] The upper end of the frame is symmetrically provided with pallet shaping mechanisms on the left and right sides. The pallet shaping mechanism includes a swing arm, the head of the swing arm is provided with a stop block, the rear part of the swing arm is hinged to the upper end of the frame, the tail of the swing arm is hinged to the cylinder rod of the swing cylinder, the cylinder body of the swing cylinder is hinged to the upper end of the frame, and the swing cylinder drives the swing arm and the stop block to swing left and right.

[0006] The beneficial effects of this utility model are:

[0007] A. By using a double-layer AGV trolley in conjunction with a lifting conveyor, the packaged ton bags can be transferred and output by the upper pallet conveyor, and then the lower pallet conveyor will transport the empty pallets to the lifting conveyor. This allows one AGV trolley to simultaneously perform the functions of empty pallet input and full bag output, which improves the overall production efficiency of the ton bag packaging unit and also greatly enhances the safety and reliability of the ton bag packaging unit.

[0008] B. When the lifting conveyor reaches its highest position, it needs to carry a full ton bag. The lateral cylinder drives the overlapping beam to move so that the overlapping beam overlaps the front and rear ends of the frame. At this time, the weight of the ton bag is borne by the overlapping beam and the frame, which solves the problems of insufficient output of the lifting cylinder and damage due to overload. The roller conveyor is always in a light load state during the lifting process. The lifting cylinder and scissor lifting mechanism replace the traditional motor or hydraulic cylinder drive method, which simplifies the structure, makes maintenance more convenient, reduces production costs, and ensures the safety and reliability of the lifting cylinder under heavy load conditions.

[0009] C. The pallet shaping mechanism, symmetrically arranged on the left and right sides of the upper part of the frame, can shape and position the empty pallet when it is raised to a high position and avoid the displacement of the ton bag when it is placed, thus providing a reliable guarantee for the smooth docking and transfer of ton bags with the double-layer AGV trolley.

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model are described in detail below with reference to the accompanying drawings. The embodiments are exemplary and intended to explain this utility model, but should not be construed as limiting this utility model.

[0017] See Figures 1-6 A ton bag packaging machine that uses AGVs to simultaneously transport full bags and supply pallets includes a ton bag filling machine 1, with a lifting conveyor 2 located below the ton bag filling machine 1. The output end of the lifting conveyor 2 can connect to a double-layer AGV trolley 3. The double-layer AGV trolley 3 includes a lower pallet conveyor 31 and an upper pallet conveyor 32. The lower pallet conveyor 31 can connect to an external pallet sorting machine and input pallets. When the lifting conveyor 2 is in the lower position, it can connect to the lower pallet conveyor 31 and transport pallets to the lifting conveyor 2. When the lifting conveyor 2 is in the upper position, it can transport full bags and pallets to the upper pallet conveyor 32 connected to it. The walking system and transmission system of the double-layer AGV trolley 3 are existing technologies and will not be described in detail here. The lower pallet conveyor 31 and the upper pallet conveyor 32 can be independently controlled and started. The ton bag filling machine 1 is also existing technology and will not be described in detail here.

[0018] Furthermore, the lifting conveyor 2 includes a frame 21, with a roller conveyor 23 located in the middle of the frame 21. A scissor-type lifting mechanism 24 is located at the lower end of the roller conveyor 23. The upper part of the scissor-type lifting mechanism 24 is hinged to the cylinder rod of a lifting cylinder 25. The cylinder body of the lifting cylinder 25 is hinged to the frame 21. The lifting cylinder 25 drives the roller conveyor 23 to move vertically. At the front and rear ends below the longitudinal beam of the roller conveyor 23, horizontally arranged overlapping beams 22 are respectively provided. The cylinder rod of the translation cylinder 29 is hinged to the cylinder body of the translation cylinder 29, which is hinged to the roller conveyor 23. When the overlapping beam 22 is in the initial position, it is located outside the frame 21. When the roller conveyor 23 is in the upper position, the translation cylinder 29 can drive the overlapping beam 22 to move horizontally back and forth. At this time, the overlapping beam 22 can overlap the upper end of the support beam of the frame 21. The weight of the ton bag is borne by the overlapping beam 22 and the frame 21. The roller conveyor 23 is preferably controlled by a motor to realize forward and reverse conveying.

[0019] Furthermore, the upper left and right sides of the frame 21 are symmetrically provided with pallet shaping mechanisms. The pallet shaping mechanism includes a swing arm 27, the head of the swing arm 27 is provided with a stop block 28, the rear part of the swing arm 27 is hinged to the upper end of the frame 21, and the tail part of the swing arm 27 is hinged to the cylinder rod of the swing cylinder 26. The cylinder body of the swing cylinder 26 is hinged to the upper end of the frame 21. The swing cylinder 26 drives the swing arm 27 and the stop block 28 to swing left and right to shape and position the pallet.

[0020] See Figures 1-6 The working principle of this utility model is explained as follows:

[0021] Lifting cylinder 25 drives roller conveyor 23 to raise the pallet to a high position. Translation cylinder 29 drives overlapping beam 22 to move horizontally so that overlapping beam 22 overlaps the upper end of frame 21. Swing cylinder 26 drives swing arm 27 and stop block 28 to swing to shape and position the pallet before returning to the initial position.

[0022] After the ton bags on the ton bag filling machine 1 are filled, they are lowered and placed on the pallet. At this time, the lower pallet conveyor 31 of the double-layer AGV trolley 3 docks with the external pallet sorting machine and inputs the pallet. The control system has controlled the double-layer AGV trolley 3 to dock with the lifting conveyor 2 along the planned route, start the roller conveyor 23 and the upper pallet conveyor 32 to transport the full bag and pallet to the upper pallet conveyor 32 docked with it, and then stop.

[0023] Then, the lifting cylinder 25 drives the roller conveyor 23 to descend to a low position. The lower pallet conveyor 31 and the roller conveyor 23 transport the pallets on the lower pallet conveyor 31 to the roller conveyor 23. The roller conveyor 23 then continues to drive the pallets to a high position to complete the packaging of the next ton bag. The double-layer AGV trolley 3, which has been docked, transports the full bag to the storage position along the planned route.
