Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to an automatic ton bag packaging system. Background Technology

[0002] In industries such as chemicals, building materials, and food, FIBCs (also known as bulk bags or FIBCs) are common material transport units. Traditional post-processing of FIBCs, such as stacking, reinforcement, and protective packaging before shipment, often relies on manual labor or semi-automatic equipment.

[0003] The existing technology has the following drawbacks: 1. Low level of automation: It requires a lot of manual labor, such as operating forklifts for handling, manually bagging, and manually bundling, resulting in low production efficiency and high labor intensity.

[0004] 2. Unstable packaging quality: Manual operation makes it difficult to guarantee the shaping effect, tightness of binding and regularity of wrapping for each package, resulting in inconsistent packaging quality, which may affect the stability and safety of goods during transportation.

[0005] 3. Poor process integration: Each process (such as stacking, bundling, and wrapping) is usually completed by independent equipment, and manual transfer and connection are required between processes, which takes up a large area and the overall process is not smooth.

[0006] 4. Limited functionality and poor flexibility: Existing production lines can usually only perform fixed processes. For example, they cannot flexibly choose whether to change to standard shipping pallets during the packaging process according to customer or transportation requirements, which limits their applicable scenarios.

[0007] Therefore, the market urgently needs a fully automated, high-quality, and highly flexible integrated packaging solution that can complete the entire process from stacking to final wrapping of ton bags. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Reference Figure 1 , 2 This embodiment discloses an automated ton bag packaging system. The system aims to achieve fully automated packaging of large-sized, flexible material bags, especially lithium battery cathode material ton bags, from feeding, stacking, shaping, bundling to final wrapping.

[0028] This system mainly includes a conveying system 120, and a first stacking machine 30, a first top strapping machine 40, a second stacking machine 60, a five-sided shaping machine 70, a subsequent strapping device, and a wrapping machine 100 arranged sequentially along the material conveying direction of the conveying system 120.

[0029] Conveying system 120 The conveyor system 120 is the "artery" that carries and transfers ton bags between workstations. In this embodiment, the conveyor system 120 mainly consists of multiple heavy-duty roller conveyor lines. The rollers are driven by motors and can carry ton bags weighing over one ton. The overall layout of the conveyor system 120 in this embodiment is U-shaped, and it also includes a first turntable 121 and a second turntable 122. The first turntable 121 and the second turntable 122 are located upstream and downstream of the five-sided shaping machine 70, respectively, to change the orientation of the ton bag stacks. The overall layout of the conveyor system 120 can be designed as a straight line or an L-shape depending on the workshop space. A centering device (not shown in the figure) and an air knife (not shown in the figure) are also provided at the entrance of the conveyor system 120. The centering device is usually composed of movable baffles on both sides to ensure that the incoming ton bags and pallets are located in the center of the conveyor line, laying the foundation for precise positioning of subsequent workstations. The air knife uses high-pressure airflow to sweep the surface of the pallets, removing dust and debris to ensure packaging cleanliness.

[0030] First stack of packages 30 The first stacker 30 is used to receive a first ton bag with a pallet and is configured to optionally perform a pallet change operation on the first ton bag. Specifically, in "pallet change mode," the first stacker 30 lifts the first ton bag from the original pallet and places it on a new pallet. As an example, the first stacker 30 includes a frame (not shown in the drawings), an X-axis drive (not shown in the drawings), a Z-axis drive (not shown in the drawings), and a hook mechanism (not shown in the drawings), with the frame serving as the main structure. The X-axis drive is typically a servo motor coupled with a ball screw or synchronous belt, driving the entire frame along the material conveying direction (X-axis) to precisely move between the initial loading position and the pallet change position. The Z-axis drive is also driven by a servo motor, controlling the frame to rise and fall in the vertical direction (Z-axis). The hook mechanism includes four retractable or rotatable hooks located below the frame for automatically hooking the four lifting straps on the top of the ton bag.

[0031] On one side, there is a pallet placement machine 20, which has multiple standard pallets pre-stored inside. When a pallet needs to be replaced, the machine can automatically release a pallet to the designated pallet replacement position on the conveyor line.

[0032] First top strapping machine 40 The first top strapping machine 40 is used to initially strap the first ton bag. The first top strapping machine 40 is existing technology, and its structure will not be described in detail here. The core functions of the first top strapping are twofold: (1) Strapping: Through a series of actions such as threading, tightening, bonding, and cutting the straps, the ton bag and the pallet are strapped in a "well" shape to initially fix them on the pallet. (2) Pre-shaping: Since the ton bag is a flexible body, it is crucial to perform preliminary shaping before stacking. The first top strapping machine 40 includes a large-size, heavy pressure plate, which is used to apply shaping pressure to the first ton bag to make its top flatter and the material denser, which greatly improves the stability and success rate of subsequent stacking.

[0033] Second stack of packaging machine 60 The function of the second stacking machine 60 is to precisely stack the second ton bag (top support) on top of the pre-shaped and bundled first ton bag to form a one-ton bag stack. Its mechanical structure is similar to that of the first stacking machine 30, also a gantry structure. The main difference is that its X-axis movement direction is perpendicular to the main material conveying direction. It grabs the second ton bag from the second loading station 50 on the side, moves it above the main conveyor line, and after the first ton bag is positioned, it descends and releases it, completing the stacking.

[0034] Five-sided shaping machine 70 The five-sided shaping machine 70 is used for the final compaction and shaping of stacked ton bag piles that are not yet uniform in shape. Its structure includes a robust frame and five shaping plates: a top shaping plate, a front shaping plate, a rear shaping plate, a left shaping plate, and a right shaping plate. The top shaping plate is driven by an upper drive mechanism (such as a cylinder or motor) to vertically compress the top of the ton bag pile. The front and rear shaping plates are positioned opposite each other and are driven by their respective drive mechanisms. The left and right shaping plates are also positioned opposite each other and are driven by their respective drive mechanisms. The front, rear, left, and right shaping plates compress the ton bag pile from four sides. After five-sided shaping, the loose ton bag pile is shaped into a regular, uniformly sized, near-cubic shape, facilitating subsequent bundling, transportation, and storage.

[0035] The subsequent strapping device is used to finally strap and secure the ton bag stack and pallet after overall shaping. In this embodiment, the subsequent strapping device includes a second top strapping machine 80 and a horizontal strapping machine 90.

[0036] Second top strapping machine 80 After shaping, the ton bag stack is immediately sent to the second top strapping machine 80. The second top strapping machine 80 has a similar structure and function to the first machine, used to vertically strap the shaped ton bag stack to the pallet in a crisscross pattern. This second top strapping machine 80 includes a large, heavy pressure plate that applies shaping pressure to the entire ton bag stack, making its top flatter and the material more compact.

[0037] Horizontal strapping machine 90 Subsequently, the ton bag stack is sent to a horizontal strapping machine 90, whose strapping track surrounds the conveyor line, performing one or more horizontal strapping passes on the middle or top and bottom of the ton bag stack. After strapping in both vertical and horizontal dimensions, the first ton bag, the second ton bag, and the pallet are securely bound together into a stable and compact whole.

[0038] 100 wrapping machine The stretch wrapping machine 100 has an existing structure, which will not be described in detail here. The bundled ton bag stacks are conveyed onto the turntable of the stretch wrapping machine 100. After the equipment starts, the turntable rotates, and simultaneously, the film frame carrying the stretch film moves up and down along the column, wrapping the four sides of the ton bag stack circumferentially. The number of wrapping layers, overlap, and tightness can all be preset in the system. After the sides are wrapped, a top covering mechanism automatically places a top film over the top of the ton bag stack, and the film frame rises again to wrap it around the edges, achieving all-around protection against dust, moisture, and unraveling.

[0039] The overall workflow of the automated ton bag packaging system in this embodiment The automated workflow of this system is carried out under the coordination of a central PLC (Programmable Logic Controller), and the specific steps are as follows:

[0040] Operators select "pallet replacement mode" or "pallet retention mode" on the touchscreen according to production needs. The first ton bag with a pallet is placed at the first loading station 10 by AGV or manually. After the ton bag enters, it is centered by the inlet centering device and the pallet is blown away by the air knife.

[0041] In the "pallet changing mode", the first stacking machine 30 runs, lifting the first ton bag from the original pallet. After the original pallet is removed and the new pallet is delivered by the pallet placement machine, the first ton bag is placed on the new pallet.

[0042] In "Tray Retention Mode", the tray changing step is skipped.

[0043] Subsequently, the first ton bag is conveyed to the first top strapping machine 40, where it is strapped in a "well" pattern. At the same time, the pressure plate on top of the first ton bag applies a pre-shaping pressure.

[0044] Meanwhile, the second ton bag is fed from the second loading station 50 and picked up by the second stacking machine 60. After the first ton bag, which has been pre-shaped and bundled, arrives at the designated location, the second stacking machine 60 precisely stacks the second ton bag on top of the first ton bag, completing the double-layer stacking.

[0045] After being rotated on a turntable, the stacked ton bags are fed into a five-sided shaping machine 70 for all-around compaction and shaping. After shaping, they immediately enter the subsequent strapping station, where the second top strapping machine 80 and the horizontal strapping machine 90 sequentially complete the vertical and horizontal reinforcement strapping.

[0046] Finally, the securely bundled stack of ton bags is conveyed to the wrapping machine 100 to complete the side and top wrapping. The packaged finished product is conveyed to the discharge port 110, and the system notifies the AGV scheduling system through the communication interface to arrange AGVs to transfer the finished product into the warehouse, realizing unmanned unloading.

[0047] In summary, this utility model provides a complete and intelligent ton bag packaging solution through the precise design and orderly linkage of each functional module. Its structural design is reasonable and its functions are comprehensive. In particular, its unique dual-mode operation and pre-shaping and shaping processes for flexible materials give it high industrial practical value and technological advancement.

[0048] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
