Description

Technical Field

[0001] This utility model relates to the field of container technology, specifically a vertical container with anti-fall safety protection. Background Technology

[0002] Containers, as a common storage and transportation tool, play an important role in commerce, industry, and daily life. They are not merely physical containers, but also products of cultural, technological, and social development. Today, the application areas of containers are constantly expanding. For example, vertical lift containers are a highly efficient automated warehousing solution widely used in manufacturing, logistics centers, and retail industries. Through vertical goods storage and retrieval operations, they significantly improve space utilization and work efficiency.

[0003] Vertical lift storage units typically consist of shelves, pallet trolleys, and pallets. The unit uses pallets as storage units, and the pallet trolleys move the goods between different locations within the unit through lifting and lowering. The lifting motion employs absolute authentication, ensuring high precision and accurate verification. Horizontal movement is controlled by inductive switches. An automatic height measuring device at the entrance detects the height of stored items, automatically and rationally arranging the storage space within the unit for intelligent management, truly achieving goods-to-person tracking.

[0004] However, because pallets lack protective devices when carrying goods for horizontal movement and lifting, there is a risk of goods falling off.

[0005] Based on this, the present invention designs a vertical container with anti-fall safety protection to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: the pallet is provided with a protective device, the protective device includes a rolled-up protective film and a driving mechanism, the protective film is synchronously unfolded or rolled up during the vertical lifting and lowering of the container through the driving mechanism.

[0007] By adopting the above technical solution, and by setting up an expandable and retractable protective film and driving mechanism, the problem of traditional vertical containers lacking fall protection is solved. When the container is raised or lowered, the protective film can automatically form a three-dimensional protective barrier, effectively preventing safety hazards caused by falling items. At the same time, the retractable design does not affect normal loading and unloading operations.

[0008] Preferably, the protective device further includes four support columns and a rolling device, wherein the support columns are rotatably disposed at the four corners of the tray, and the protective film is rolled around the outside of the support columns.

[0009] By adopting the above technical solution, a combination structure of four corner support columns and a rolling device is used to make the protective film form a stable quadrilateral protective surface when it is unfolded, thereby improving its impact resistance; the rolling storage saves space and avoids damage to the protective film by wrinkles.

[0010] Preferably, the surface of the tray is provided with a guide groove, the two ends of the guide groove are respectively connected to the adjacent support column, and the bottom of the guide groove is provided with a cavity.

[0011] By adopting the above technical solutions, the guide groove design makes the protective film unfolding path precisely controllable, and the cavity structure hides the driving components, ensuring smooth operation of the mechanism.

[0012] Preferably, the driving mechanism includes a motor, a screw, and a slider. The motor is fixedly installed in the cavity. One end of the screw is coaxially connected to the output shaft of the motor, and the other end is rotatably connected to the inner wall of the cavity through a bearing. The bottom of the slider is threadedly engaged with the screw, and the top passes through a guide groove and is fixedly connected to the edge of the protective film.

[0013] By adopting the above technical solution, the screw-slider transmission mechanism converts the rotational motion of the motor into linear motion, thereby improving transmission efficiency; the self-locking characteristic of the thread can fix the protective film at any position to prevent accidental rewinding.

[0014] Preferably, the winding device is a torsion spring, which is disposed inside the support column and fixedly connected to the inner wall of the support column.

[0015] By adopting the above technical solution, the torsion spring mechanism provides automatic winding force, reduces motor load, and improves the winding effect of the protective film.

[0016] Preferably, the edge of the protective film is provided with reinforcing ribs, and the reinforcing ribs are rigidly connected to the slider.

[0017] By adopting the above technical solution, the reinforcing rib structure improves the tear resistance of the protective membrane edge and extends its service life.

[0018] Preferably, the reinforcing rib is obliquely connected to the slider.

[0019] By adopting the above technical solution, the protective film unfolds to form an inclined protective surface. The inclined protective surface causes falling objects to slide down the slope to the designated area, which reduces the risk of rebound compared to a vertical protective surface, and also makes it easier to collect scattered items.

[0020] In summary, this application has the following beneficial technical effects: by setting up an unfoldable and retractable protective film and a drive mechanism, the problem of traditional vertical containers lacking fall protection is solved. When the container is raised or lowered, the protective film can automatically form a three-dimensional protective barrier, effectively preventing safety hazards caused by falling items. At the same time, the retractable design does not affect normal loading and unloading operations. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] A vertical container with anti-fall safety protection includes a shelf 1, a pallet 2, and a protective device installed on the pallet 2. The pallet 2 is square flat. The protective device includes four support columns 6, a protective film 5, a drive mechanism, and a rolling device. The support columns 6 are rotatably installed at the four corners of the pallet 2. An adhesive layer is provided on the support columns 6. One end of the protective film 5 is pasted on the adhesive layer, and the other end of the protective film 5 is rolled around the support column 6.

[0032] In use, the protective film 5 is controlled by the drive device to slide one end, so that the protective film 5 moves along the side of the pallet 2 until it moves to the vicinity of the next support column 6. At this time, all four sides of the pallet 2 are covered, and the goods on the pallet 2 are limited by the protective film 5, which can prevent the goods from falling during the movement of the pallet 2 and improve the safety of the vertical container operation.

[0033] The surface of the tray 2 is provided with a guide groove 3. The two ends of the guide groove 3 are respectively connected to the adjacent support column 6. The bottom of the guide groove 3 is provided with a cavity 9. A drive mechanism is provided in the cavity 9. The drive mechanism includes a motor 12, a screw 10 and a slider 11. The motor 12 is fixedly installed in the cavity 9. One end of the screw 10 is coaxially connected to the output shaft of the motor 12, and the other end is rotatably connected to the inner wall of the cavity 9 through a bearing. The bottom of the slider 11 is threadedly engaged with the screw 10, and the top passes through the guide groove 3 and is fixedly connected to the edge of the protective film 5.

[0034] When the motor 12 starts, the screw 10 begins to rotate. The slider 11 on the screw 10 continuously meshes with the screw 10, causing the slider 11 to slide along the guide groove 3, thereby driving the protective film 5 to unfold or rewind along the guide groove 3. This allows the unfolding and rewinding of the protective film 5 to be controlled more precisely, improving transmission efficiency.

[0035] The rolling device includes a torsion spring 8. A receiving cavity 4 is provided in the support column 6. The torsion spring 8 is located in the receiving cavity 4. One end of the torsion spring 8 is fixedly connected to the tray 2, and the other end of the torsion spring 8 is fixedly connected to the inner wall of the support column 6. The protective film 5 is pulled and rolled back by the torsion spring 8, so that the protective film 5 can be better stored. The edge of the protective film 5 is provided with reinforcing ribs 7. The reinforcing ribs 7 are rigidly connected to the slider 11. There is an angle between the reinforcing ribs 7 and the vertical direction of the slider 11, so that the protective film 5 forms an inclined protective surface after being unfolded. The reinforcing ribs 7 can enhance the stability of the protective film 5, extend the service life of the protective device, and expand the protection range of the protective film 5, making it easier to collect scattered items.

[0036] The implementation principle of this embodiment is as follows: When in use, the motor 12 is started, the screw 10 starts to rotate, and the slider 11 on the screw 10 continuously meshes with the screw 10, causing the slider 11 to slide along the guide groove 3. One end of the protective film 5 begins to unfold and moves along the side of the pallet 2 until it moves to the vicinity of the next support column 6. At this time, all four sides of the pallet 2 are covered, and the goods on the pallet 2 are limited by the protective film 5, which can prevent the goods from falling off during the movement of the pallet 2. When it is necessary to load or unload goods, the motor 12 is rotated in the opposite direction, causing the slider 11 to move in the opposite direction. The slider 11 drives the protective film 5 to retract, and the torsion spring 8 pulls the support column 6 to rotate, so that the protective film 5 can be stored in the support column 6 more quickly.
