Description

Technical Field

[0001] The invention relates to the technical field of packaging and transportation, in particular to a wooden packaging outer film-coated packaging and transportation machine. Background Art

[0002] Wooden crates are a widely used type of shipping packaging container, known for their durability and strong load-bearing capacity. They are usually made of solid wood or man-made panels, such as plywood, medium-density fiberboard (MDF), etc. Wooden crates are particularly suitable for loading heavy or fragile items due to their good impact resistance and protective properties. In addition, wooden crates can be customized according to the size and shape of the goods, providing precise protection. They are easy to stack and carry, which facilitates logistics operations. Wooden crates also have environmental advantages because wood is a renewable resource and most wooden crates can be recycled and reused. However, they also have some disadvantages, such as heavy weight, which may increase transportation costs, and easy deformation in humid environments. Despite this, wooden crates are still the preferred packaging solution for many industries due to their practicality and reliability.

[0003] However, as mentioned above, dampness in wooden packaging boxes is a common problem, especially in humid and rainy areas. A damp wooden box will not only reduce its own strength and durability, but may also cause damage to the packaged items. A damp wooden box may become moldy, deformed, or even rot, which will affect the structural integrity and protective performance of the wooden box. At the same time, if the wooden box continues to be placed on the wet ground, the moisture will continue to spread upwards, and then spread through the wooden box to the items inside the wooden box, eventually causing the items inside the wooden box to be wetted by moisture or the spreading moisture.

[0004] Therefore, before express delivery, wooden packaging boxes often need to be wrapped with film on the outside for moisture-proof treatment. On the one hand, wooden packaging boxes are large in size, and on the other hand, they are heavy. Therefore, if people need to cover and transport wooden packaging boxes, they often need a forklift to cooperate. Even if a forklift cooperates with manual labor to wrap the film on the outside of the wooden packaging box, it cannot be completed in a short time. In the process of lifting the wooden packaging box to wrap the film, the wooden packaging box may even fall and hit the worker, causing safety problems.

[0005] Therefore, a wood packaging outer film packaging conveyor is proposed to solve or alleviate the above problems. Summary of the invention

[0060] When the present invention actually transports the wooden packaging box 26, only two workers, two forklift operators, and two forklifts are required. The forklift operator controls the forklift to transport the wooden packaging box 26 to the bottom of the fastener upper component assembly, and the image acquisition module 23 in the orientation correction system takes a picture of the top surface image of the wooden packaging box 26 and feeds it back to the data processing module 24 in the orientation correction system. The data processing module 24 processes the top surface image fed back, and finds the coordinates of the four inner corners of the wooden packaging box 26 in the top surface image, and then transmits the coordinates of the four inner corners of the wooden packaging box 26 to the control module 25. The control module 25 controls the upper horizontal electric slide rail 3, the upper longitudinal electric slide rail 4, the vertical electric slide rail 5, the lower horizontal electric slide rail 6, and the lower longitudinal electric slide rail 8, and then causes the rotating clamping assembly 10 disposed on the longitudinal mounting slide 9 to move, so that the rotating clamping assembly 10 can move to the four inner corner positions of the wooden packaging box 26.

[0061] Then the rotary clamping assembly 10 will move again until the pneumatic finger 104 in the rotary clamping assembly 10 can move above the buffer track 1102, and then the air pump will work, and then the air pump can adjust the air pressure through the sequence of the hose, the pneumatic rotary joint 103, and the pneumatic finger 104, so that the pneumatic finger 104 can clamp the connecting ring in the fastener, and then drive the fastener to move above the four inner corners of the wooden packaging box 26, and then driven by the vertical electric slide rail 5, the rotary clamping assembly 10 moves downward, and then the servo motor 102 is started, so that the servo motor 102 drives the pneumatic hand The pneumatic finger 104 rotates, and the pneumatic finger 104 drives the fastener to rotate together. During the rotation of the pneumatic finger 104, the rotating end of the pneumatic rotary joint 103 can rotate along with the pneumatic finger 104, and can still maintain the flow of air without affecting the airflow in the pneumatic finger 104. Driven by the rotation of the pneumatic finger 104, the fastener is drilled into the four inner corners of the wooden packaging box 26, and the vertical electric slide rail 5 drives the rotating clamping assembly 10 to move downward, thereby completing the assembly action of the fastener on the wooden packaging box 26, and then the pneumatic finger 104 releases the fastener;

[0062] Then the forklift operator controls the forklift to drive the wooden packaging box 26 with the fasteners assembled to move to the bottom of the transport rack 12, and then the worker fixes the lower ends of the four lower pull ropes 17 to the connecting rings in the fasteners on the wooden packaging box 26, and the control module 25 controls the control motor 1309 to rotate, so that the control motor 1309 drives the take-up roller to rotate, and the take-up roller reels the upper pull rope 14, and then lifts the wooden packaging box 26, and then the forklift operator can control the forklift to carry the next wooden packaging box 26, and when the wooden packaging box 26 lifted by the displacement lifting assembly 13 needs to be displaced, the control module 25 can control the drive motor 1303 to work, and the drive motor 1303 drives the drive wheel 1304 to rotate, and then the displacement lifting assembly 13 rolls in the H-shaped rail 1202, so that the displacement lifting assembly 13 drives the wooden packaging box 26 to displace in the length direction of the transport rack 12, and transports it from one end to the other end;

[0063] During the transportation process, when the wooden packaging box 26 is moved to the middle position of the transport frame 12, that is, the wooden packaging box 26 is located directly above the limit frame 18, the worker will open the bag-shaped heat shrink film in the limit frame 18 in advance, and then the displacement and lifting assembly 13 will drive the wooden packaging box 26 to move downward into the bag-shaped heat shrink film, and the heating fan 21 can control the heating of the electric heating wire therein, and the heating fan 21 starts to work, and the hot air is blown toward the limit frame 18 and the bag-shaped heat shrink film through the Y-shaped tube 20. The bag-shaped heat shrink film is blown to wrap the outer side of the wooden packing box 26. After the wrapping and laminating action is completed, the displacement and pulling component 13 drives the wooden packing box 26 to lift up, and then continues to perform horizontal displacement to complete the transportation of the wooden packing box 26. In this process, the wooden packing box 26 can also complete the laminating action, which can prevent environmental moisture and water from invading the wooden packing box 26 from the bottom surface and the outer peripheral wall of the wooden packing box 26, and prevent the items in the wooden packing box 26 from being affected by moisture and water.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
