Description

Technical Field

[0001] This utility model relates to the field of material loading technology, and in particular to an automatic material loading system. Background Technology

[0002] Currently, loading of materials, especially high-sided trucks, is typically done manually or semi-automatically. Manual loading requires workers to move materials one package at a time, which is inefficient and labor-intensive. Pallet retrieval is also a cumbersome process, requiring additional manpower and time. While some existing loading systems have achieved partial automation, they are prone to damage during high-sided truck loading due to the tedious operation of opening and closing the side panels and the small gaps between the side panels. Furthermore, existing loading systems often lack effective shaping and stacking functions, resulting in inconsistent cargo dimensions and small gaps between the cargo and the side panels, increasing the risk of damage. Therefore, there is a need to design an automated loading system capable of automatically retrieving, unloading, and returning pallets, with shaping and stacking functions, to reduce labor intensity, lower material handling damage rates, and improve material handling efficiency. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an automatic loading system for stacked materials. This invention has a high degree of automation, realizing full-process automation from warehousing, pallet removal, shaping and stacking to loading and pallet recycling, significantly improving loading efficiency, reducing labor intensity, and is particularly suitable for loading high-sided trucks, solving the problems of cumbersome side panel opening and closing operations and small gaps between side panels.

[0005] To achieve the above objectives, the technical solution of this utility model is: an automatic loading system for stacked materials, comprising:

[0006] Material conveying device, used for conveying palletized materials;

[0007] A vertical clamping and flipping device is used to clamp and flip palletized materials located on the material conveying device and to obtain the pallets;

[0008] Loading platform, used to place loaded materials;

[0009] A shaping and stacking device for shaping and stacking the loaded material located on the loading platform;

[0010] The integrated material preparation and loading device is used to transport the stacked materials located on the vertical clamping and turning device to the loading platform and to transport the stacked materials located on the loading platform to the vehicle.

[0011] A pallet recycling device for recycling pallets from the vertical bag-turning device.

[0012] This utility model incorporates a material conveying device, a vertical clamping and turning device, a loading platform, a shaping and stacking device, an integrated material preparation and loading device, and a pallet recycling device. This results in a high degree of automation in loading materials onto trucks. From warehousing, unpalletizing, shaping and stacking to loading and pallet recycling, the entire process is automated, significantly improving loading efficiency, reducing labor intensity, and lowering the damage rate of materials during handling. It is particularly suitable for loading high-sided trucks, solving the problems of cumbersome side panel opening and closing operations and small side panel gaps.

[0013] In some embodiments, the vertical bag-clamping and turning device includes a rotating body, a roller clamping arm, a fixed pallet clamping arm, and a comb-tooth tubular clamping arm. The roller clamping arm is disposed on one side of the rotating body, the comb-tooth tubular clamping arm is disposed on the other side of the rotating body, and the fixed pallet clamping arm is disposed on the roller clamping arm. This invention, through the design of the vertical bag-clamping and turning machine, achieves an automatic pallet removal function. It flips palletized materials 180 degrees and removes the pallet, leaving the materials in a pallet-free state for easier subsequent loading.

[0014] In some embodiments, the loading platform includes a comb-tooth buffer platform and a lifting platform, the lifting platform being vertically and flexibly nested within the comb-tooth buffer platform. This invention, by setting up a loading platform, facilitates the receipt of palletless stacked materials processed by the vertical clamping and turning device. The comb-tooth buffer platform provides temporary storage and positioning for the materials, ensuring their stability during transport. The lifting function of the lifting platform allows for flexible adjustment of the material height according to the operational needs of the subsequent shaping and stacking device, ensuring precise alignment of the materials with the shaping and stacking process. This effectively avoids material offset or stacking misalignment caused by height mismatch, further enhancing the continuity and automation level of the entire system.

[0015] In some embodiments, the shaping and stacking device includes horizontal clamping arms disposed on both sides of the comb-tooth buffer table. This invention, by providing two horizontal clamping arms, shapes and stacks the unpalletized material, ensuring the two stacks are tightly joined and their size is reduced. This provides a greater safety clearance between the material and the sideboard of the high-sided truck during loading, preventing material damage.

[0016] In some embodiments, the stroke of one horizontal clamping arm is greater than the stroke of the other horizontal clamping arm. This invention, by providing horizontal clamping arms on both sides of the comb-tooth buffer platform, with the strokes of the two horizontal clamping arms being inconsistent, is designed to avoid the comb-tooth forks of the integrated material preparation and loading device.

[0017] In some embodiments, both horizontal clamping arms are controlled independently. This design allows the two horizontal clamping arms to independently extend and retract based on the actual material size, stacking state, and relative position to the comb forks of the integrated material preparation and loading device. When dealing with materials of different sizes, the movement distance of the two clamping arms can be controlled separately to ensure that while effectively shaping and stacking the material, the movement trajectory of the comb forks is precisely avoided, preventing mechanical interference. This individual control method greatly improves the flexibility and adaptability of the shaping and stacking operation, better meets the processing needs of diverse materials, and further ensures the stable operation and operational accuracy of the entire loading system under complex working conditions.

[0018] In some embodiments, the material conveying device includes an AGV, a discharge conveyor line, a roller conveyor, an overhead lateral conveyor chain, a chain conveyor, and a lifting roller conveyor. This invention, through reasonable combination and connection, forms a flexible conveying network covering multiple stages such as material transfer, temporary storage, and position adjustment. The AGV, as the core equipment for automated material transfer, can flexibly shuttle between the warehouse and loading area, achieving precise point-to-point material delivery. The discharge conveyor line and roller conveyor undertake the continuous conveying of materials from the production end or storage area to the loading front, ensuring that materials enter the next processing stage in sequence. The overhead lateral conveyor chain can utilize overhead space to achieve lateral material transfer, effectively saving ground layout space. The chain conveyor, with its strong load-bearing capacity, is suitable for long-distance transport of heavy-duty materials. The lifting roller conveyor has lifting and adjustment functions, enabling smooth transition and docking of materials between conveying devices at different heights, meeting the collaborative operation needs of multi-level conveying systems.

[0019] In some embodiments, the discharge conveyor line includes multiple conveying paths. This invention provides multiple conveying paths for alternately conveying materials to the vertical clamping and turning device.

[0020] In some embodiments, the integrated material preparation and loading device includes a trolley, a hoist, a tilting machine, and comb-tooth forks. This invention provides an integrated material preparation and loading device with a trolley, a hoist, a tilting machine, and comb-tooth forks to achieve the functions of picking up, lifting, tilting, lateral movement, and unloading goods.

[0021] In some embodiments, the pallet recycling device includes a chain conveyor and a pallet stacking machine. This invention achieves the functions of pallet conveying and recycling by incorporating a chain conveyor and a pallet stacking machine.

[0022] The working principle of this utility model is as follows:

[0023] The AGV transports palletized materials to the discharge conveyor line, where they are conveyed via roller conveyor, top transverse chain conveyor, chain conveyor, and lifting roller conveyor to the vertical bag-turning device.

[0024] The vertical clamping and flipping device clamps and flips palletized material by 180 degrees, and uses fixed pallet clamping arms to hold the pallet so that the pallet is detached from the palletized material. At this time, the palletized material is in a pallet-free state.

[0025] The integrated material preparation and loading device advances to grip, lift, and rotate the loaded material 180 degrees. It then retreats and moves laterally to place the material on the comb-tooth buffer table for shaping. Simultaneously, after the integrated material preparation and loading device forks out the loaded goods from the comb-tooth tubular gripping arm of the vertical bag-turning machine, the rotating body of the vertical bag-turning device rotates 180 degrees, so that the comb-tooth tubular gripping arm is above and the roller gripping arm containing the fixed pallet is below. The comb-tooth tubular gripping arm and roller gripping arm of the vertical bag-turning device open, making the roller conveying surface of the roller gripping arm flush with the lifting roller conveyor. The fixed pallet gripping arm on the roller gripping arm opens, the roller reverses, and the pallet is returned to the lifting roller conveyor. The lifting roller conveyor descends, causing the empty pallet to fall onto the chain conveyor below. The chain conveyor transports the pallet to the pallet stacking machine for pallet stacking. After the pallet stacking machine has stacked the entire batch, it is sent to the pallet collection port and then forked by the AGV to the working area of ​​the packaging line.

[0026] The lifting platform rises, making the bottom surface of the stacked material flat. The two horizontal clamping arms of the shaping and stacking device clamp the goods, making the goods close together and reducing their size. The two horizontal clamping arms of the shaping and stacking device open, and the lifting platform descends.

[0027] The comb-tooth forks of the integrated material preparation and loading device enter the comb-tooth buffer platform to pick up the shaped and stacked material, and then flip it 180 degrees by a tilting machine. It enters from the rear of the high-sided truck, moves it in the air to the vehicle flatbed, and places the stacked material on the vehicle flatbed.

[0028] In summary, the beneficial effects of this utility model are:

[0029] This utility model achieves automatic pallet removal function by setting up a vertical clamping and flipping device. After flipping the palletized material 180 degrees, the pallet is removed, so that the material is in a pallet-free state, which is convenient for subsequent loading.

[0030] This utility model achieves the shaping and stacking of stacked materials through the cooperation of an integrated material preparation and loading device, a lifting platform, and a shaping and stacking device. This makes the two stacks of goods close together and smaller in size, providing more safety gaps with the sideboards of the high-sided truck during loading and avoiding damage to the goods.

[0031] This invention utilizes a pallet recycling device comprising a chain conveyor, a pallet stacker, and an AGV to achieve automatic pallet recycling and stacking, reducing manual intervention and improving efficiency.

[0032] The entire system of this utility model is highly automated. From warehousing, unloading, shaping and stacking to loading and pallet recycling, it realizes full-process automation, significantly improves loading efficiency, reduces labor intensity, and is particularly suitable for loading high-sided trucks, solving the problems of cumbersome side panel opening and closing operations and small side panel gaps.

[0067] This utility model incorporates a chain conveyor 62 and a palletizer 61 to achieve the functions of pallet conveying and recycling.

[0068] The working principle of this utility model is as follows:

[0069] The AGV12 transports palletized materials to the discharge conveyor line 11. The palletized materials are then transported to the vertical bag-turning device 2 via the roller conveyor 13, the top transverse chain conveyor 14, the chain conveyor 15, and the lifting roller conveyor 16.
