Description

Technical Field

[0001] This utility model belongs to the field of pipe packaging technology, specifically relating to an automatic pipe packaging unloading trolley device. Background Technology

[0002] In the pipe manufacturing industry, packaging is a crucial step before products leave the factory, directly affecting the safety of pipe transportation, storage stability, and appearance integrity. Automated unloading and transfer of stacked pipes is one of the core components for improving the efficiency of packaging production lines.

[0003] Currently, the stacking and unloading methods in the pipe packaging process are mainly divided into two categories: manual stacking and unloading, and mechanical stacking and unloading. Manual stacking and unloading relies on operators using mobile carts, forklifts, and other equipment to transport the stacked pipes. This method has several inherent drawbacks: Firstly, pipes are often long and heavy, and improper handling during manual transport can easily cause them to slip or collide, resulting in scratches and deformation on the pipe surface, reducing the product qualification rate. Secondly, the transport efficiency is greatly affected by the operator's skill level and physical strength, making it unsuitable for the production needs of high-speed packaging lines. Furthermore, operators need to work frequently, resulting in high labor intensity, and there are safety hazards such as being squeezed or collided with by the pipes.

[0004] Most existing mechanical stacking and unloading devices stack pipes on a feeding platform. After the feeding mechanism removes the stacked pipes from the feeding platform, it is necessary to wait for the feeding mechanism to reset before the next batch of pipes can be stacked. This results in idle waiting time on the feeding platform, making it impossible to achieve parallel operation of pipe stacking and transfer and unloading, which seriously restricts the production efficiency of the overall packaging production line.

[0021] See Figures 1 to 4 This embodiment discloses an automatic unloading trolley device for pipe packaging, including at least one movable frame 1 and a fixed frame 2. The movable frame 1 is movably connected to the fixed frame 2. At least one set of first baffle arms 3 and a first baffle driving device 4 for moving the first baffle arms 3 to move down and avoid obstacles are installed on the movable frame 1. The first baffle driving device 4 is connected to the first baffle arms 3. The movable frame 1 is also equipped with a lifting device 5 for lifting pipes and a trolley driving device 6 for moving the movable frame 1 back and forth along the fixed frame 2. The fixed frame 2 is equipped with a feeding platform 7 for stacking pipes, a second baffle arm 8 for preventing pipes from rolling out of the feeding platform 7, and a second baffle driving device 9 for moving the second baffle arm 8 to move down and avoid obstacles. The feeding platform 7 and the second baffle arm 8 cooperate to form a stacking area 10 for unloading and stacking pipes. The second baffle driving device 9 is connected to the second baffle arm 8. When discharging pipes, the second baffle drive device 9 drives the second baffle arm 8 to rise, and multiple pipes are stacked on the discharge platform 7. When a certain number of pipes are stacked on the discharge platform 7, the trolley drive device 6 operates, driving the moving frame 1 to move closer to the discharge platform 7. The first baffle drive device 4 drives the first baffle arm 3 to fall down, and the moving frame 1 can move to a position below the pipes stacked on the discharge platform 7. After the moving frame 1 moves below the pipes, the first baffle drive device 4 drives the first baffle arm 3 to rise, and the stacked pipes enter the first baffle arm 3. Then, the second baffle drive device 9 drives the second baffle arm 8 to fall down, allowing the pipes to be moved out of the discharge platform 7. The lifting device 5 rises and lifts the pipes upward, causing the pipes to detach from the discharge platform 7, avoiding friction between the pipes and the discharge platform 7 when they are moved out, and ensuring the product qualification rate. Finally, the trolley drive device 6 operates, and the pipes are moved out with the moving frame 1, thereby realizing automatic discharge, reducing labor intensity, and improving the safety of pipe discharge. After the pipe is removed from the unloading platform 7, the second baffle drive device 9 drives the second baffle arm 8 to rise, and the pipe can continue to be unloaded onto the unloading platform 7. There is no need to wait for the moving frame 1 to return before the next batch of pipes can be stacked, realizing the parallel operation of pipe stacking and transfer unloading, and improving packaging unloading efficiency.

[0022] In a preferred embodiment, two fixed frames 2 are provided, each connected to one end of a movable frame 1. The movable frame 1 moves horizontally along the length of the two fixed frames 2.

The rotating crossbeam 31 passes through the bearing 45 and is rotatably connected to the bearing seat 44. When the first drive telescopic cylinder 42 extends, the first connecting rotating arm 43 drives the rotating crossbeam 31 to rotate, causing the two first material-stopping columns 32 to flip downwards, thereby driving the first material-stopping arm 3 to change from a raised state to a lowered state. Conversely, when the first drive telescopic cylinder 42 retracts, the first connecting rotating arm 43 drives the rotating beam 31 to rotate in the opposite direction, causing the two first material-stopping columns 32 to flip upward, thereby causing the first material-stopping arm 3 to change from the lowered state to the raised state.

When the second drive telescopic cylinder 92 extends, it drives the second stop arm 8 to rotate upward via the second connecting rotating arm 93, changing the second stop arm 8 from a lowered state to a raised state. Conversely, when the second drive telescopic cylinder 92 retracts, it drives the second stop arm 8 to rotate downward via the second connecting rotating arm 93, changing the second stop arm 8 from a raised state to a lowered state. To improve the stability of the second stop drive device 9, a guide rail 95 is installed on the second fixed frame 91, and a roller 96 is installed at the connection end between the second drive telescopic cylinder 92 and the second connecting rotating arm 93.
