Description

Technical Field

[0001] The utility model relates to the technical field of logistics warehousing, and more specifically to an anti-collapse lifting stack auxiliary mechanism. Background Art

[0002] With the acceleration of modern industrial automation, the logistics and warehousing industry is undergoing unprecedented changes. In order to cope with the growing demand for production efficiency and the challenge of limited storage space, efficient and accurate material handling and palletizing technology is particularly important. Especially in the fields of food, chemical industry, agriculture, etc., a large number of bag products with gas-filled packaging (such as nitrogen preservation) are used. Although this type of packaging can effectively extend the shelf life of the product, its unique elasticity and rolling properties can easily cause unstable stacking or even collapse during the automated palletizing process, which seriously affects the warehouse utilization rate and operational safety. Therefore, the market urgently needs an intelligent palletizing solution that can effectively solve such problems in order to adapt to the rapidly developing trend of Industry 4.0.

[0003] Traditional anti-collapse lifting and stacking auxiliary mechanisms focus more on improving the load-bearing capacity and operational stability of the equipment, and realize basic stacking functions by strengthening the mechanical structure and optimizing the drive system. For example, heavy steel structures, high-performance motors and precise control systems are used to ensure the smoothness and accuracy of the lifting process. However, faced with packaging bags with high gas content and easy to bounce and roll, these traditional designs often seem powerless. They lack refined processing measures for specific material characteristics, especially in stacking shaping and preventing stacking collapse. They mainly rely on manual intervention or simple physical blocking, which is not only inefficient, but also difficult to ensure the consistency and stability of stacking quality. In addition, traditional palletizing equipment often ignores the effective constraints on bagged products during dynamic operations, which increases the difficulty of operation and safety hazards.

[0004] In the anti-collapse lifting and palletizing auxiliary mechanism that is not equipped with a shaping frame, bag products with high gas content face many challenges during the palletizing process. First, due to the lack of effective restraint means, these bags are prone to bounce due to their own elasticity when stacked, which not only makes it difficult to arrange them neatly, but also causes the stacked shape to loosen, affecting the overall stability and aesthetics of the stack. Secondly, the rolling characteristics of bagged products make it easy for them to shift or even roll off during palletizing, which not only increases the risk of palletizing failure, but may also cause product damage, affecting product quality and subsequent logistics efficiency. In addition, the palletizing system without a shaping frame design often requires more manual intervention for manual sorting and adjustment during operation, which undoubtedly increases labor costs and reduces the degree of automation and production efficiency. What's more serious is that the occurrence of a collapse accident will not only lead to economic losses, but may also cause safety accidents, posing a threat to the safety of operators.

[0005] Therefore, the utility model discloses an anti-collapse lifting and stacking auxiliary mechanism, which can not only effectively limit the bouncing and rolling of bagged products, but also ensure the continuity of the stacking operation and the neatness of the stack shape, and is an indispensable part of the modern intelligent warehousing system.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this utility model.

[0034] like Figure 1-Figure 5 As shown, an anti-collapse lifting stack auxiliary mechanism includes a column welding body 1, the column welding body 1 is vertically fixed on the column base steel plate 5, and the top of the column welding body 1 is closed with a column top cover 6; a lifting reducer 3 and a lifting servo motor 4 are arranged above the column top cover 6; a gear shield 7 is arranged on the gear side of the lifting reducer 3; the output of the lifting servo motor 4 is transmitted to the slider 8 through a chain connection after being decelerated and torque-increased by the lifting reducer 3, so as to perform a lifting action; the front end face of the column welding body 1 is connected to the linear guide rail by bolts, and the linear guide rail 9 includes a first linear guide rail and a second linear guide rail; the first linear guide rail and the second linear guide rail The linear guide is covered with a column accordion cover 2 to prevent dust and water; a slider 8 is arranged in the first linear guide and the second linear guide; the slider 8 is tightly connected to one end of the cross arm steel pipe 11 through the cross arm connecting plate 10, and the cross arm steel pipe 11 is reinforced with a cross arm small rib plate 12 and a cross arm rib plate 13 on the upper and lower parts to enhance the load-bearing and stability, and the other end of the cross arm steel pipe 11 is connected to the square pile 14 by welding; a column wire trough cover plate 15 is arranged on the outer side of the side end face of the column welding body 1; the cables of the lifting reducer 3 and the lifting servo motor 4 are arranged in order through the column wire trough cover plate 15; a column observation hole cover plate 16 is arranged in the middle of the rear end face of the column welding body 1.

[0035] Among them, the first linear guide and the second linear guide are arranged in parallel to ensure the stable movement of the slider 8 in the vertical direction. The slider 8 is tightly combined with the linear guide through a linear bearing. The square ridge stack 14 is made of galvanized steel material, and the square ridge stack 14 is arranged in a regular square shape, including a reinforcing rib, a rib and a fixed plate; the reinforcing rib is connected to the rib through the fixed plate. The rib is perpendicular to the wall, and its upper part is open outward. The fixed plate and the reinforcing rib are fixed by hexagonal bolts, and the edge of the rib opening is rounded. The square ridge stack 14 is connected to the cross arm steel pipe 11 by welding and bolting. The output shaft of the lifting servo motor 4 is directly connected to the input shaft of the lifting reducer 3 through a coupling to form an integrated power transmission system. The cross arm steel pipe 11 includes a first workpiece, a second workpiece and a third workpiece; the first workpiece and the third workpiece are arranged in parallel; the second workpiece is located between the first workpiece and the third workpiece, and is perpendicular to the first workpiece and the third workpiece.

[0036] In the specific embodiment, the column welded body 1 is welded with high-strength steel as the supporting frame of the entire mechanism, ensuring the structural stability and load-bearing capacity of the entire mechanism. It is vertically fixed on the column base steel plate 5, and the top is closed with a column top cover 6, forming a stable vertical support system. The column welded body 1 not only bears the weight of the entire mechanism, but also provides a precise positioning reference for other key components such as linear guides, sliders 8, etc., and is the cornerstone of the stable operation of the entire stacking system.

[0037] The linear guide system consists of a first linear guide and a second linear guide, which are fixed to the front end face of the column welded body 1 by bolts. The two guides are arranged in parallel to ensure the smooth movement of the slider 8 in the vertical direction. The column accordion cover 2 covered thereon is effective in preventing dust and water, protecting the internal mechanical structure from pollution. The slider 8 is closely matched with the linear guide, and the ball bearing realizes low-friction and high-precision linear motion, ensuring the smooth transition of the bagged products during the lifting process, which is the key to achieving the continuity of the palletizing operation and the neatness of the stacking shape.

[0038] The lifting servo motor 4 is used as a power source and is efficiently combined with the lifting reducer 3. Through the precise chain transmission system, the lifting and lowering action of the slider 8 is precisely controlled. The high-precision encoder of the servo motor ensures the high precision of the motor speed and position feedback, so that the control system can accurately control the lifting action, while the reducer converts the high-speed rotation of the motor into a low-speed, high-torque motion suitable for the lifting of the slider 8, ensuring the stability and repeated positioning accuracy during the stacking process.

[0039] The square ridge stack 14 is designed as a liftable frame structure, whose size matches the bagged product and can fit the bagged product closely, effectively limiting its bouncing and rolling during the palletizing process. As the palletizing height increases, the square ridge stack 14 automatically adjusts to the height of the current palletizing layer through linkage with the main body of the mechanism, always keeping the bagged product restrained until the palletizing operation is completed. The key to this mechanism is the precise synchronization between the square ridge stack 14 and the main body of the mechanism, which ensures that the square ridge stack 14 can adapt to the changes in the stack height in real time and maintain the neatness of the stack shape.

[0040] The cross arm steel pipe 11 is closely connected to the slider 8 through the cross arm connecting plate 10. The cross arm small ribs 12 and cross arm ribs 13 reinforced above and below significantly enhance the load-bearing capacity and structural stability of the cross arm. The other end of the cross arm steel pipe 11 is connected to the square ridge stack 14 by welding, forming a direct support surface for the stacking operation. These designs ensure the stability of the cross arm when bearing the weight of the bagged products. At the same time, the grid-like support structure of the cross arm ribs 13 significantly improves the rigidity and bending resistance of the cross arm, ensuring the structural stability under heavy loads.

[0041] In a specific application, the operator starts the system, the lifting servo motor 4 and the reducer start running, the slider 8 is at the lowest position, the shaping frame is adjusted to the initial height, and is ready to receive the first layer of bagged products. The bagged products reach the designated position through the conveying system, and the slider 8, driven by the servo motor and the reducer, rises steadily along the linear guide rail to lift the bagged products to a predetermined height. In this process, the square ridge stack 14 is dynamically adjusted according to the current stacking height to always maintain effective constraints on the bagged products. As the bagged products are stacked layer by layer, the square ridge stack 14 rises accordingly, ensuring that each layer of bagged products can remain stable during stacking and form a neat stack shape. The structural design of the cross arm steel pipe 11 and the cross arm rib plate 13 enhances the load-bearing capacity and stability, and ensures the safety and reliability of the stacking operation. When the preset stack height is reached, the stacking operation is suspended, the square ridge stack 14 returns to the initial position, and the slider 8 drops to the lowest point, completing a complete stacking cycle. At this time, the stacked bagged products have a neat shape and good stability, which is convenient for subsequent handling and storage. The setting of the column observation hole cover plate makes it easy for the operator to monitor the operating status of the mechanism in real time, find and eliminate faults in time, and ensure the continuous optimization and intelligent management of palletizing operations. Regular maintenance, such as lubricating the guide rails and checking the status of the motor and reducer, is also an important part of ensuring the long-term stable operation of the system.

[0042] The implementation of the anti-collapse lifting and stacking auxiliary mechanism not only effectively solves the bouncing and rolling problems during the palletizing of bagged products, significantly improves the efficiency and safety of palletizing operations, but also has a profound impact on the overall operation of the warehousing and logistics industry. Through the application of shaping frames and dynamic adjustment mechanisms, the anti-collapse lifting and stacking auxiliary mechanism ensures the continuity of palletizing operations and the neatness of the stack shape, greatly reduces the risk of collapse caused by unstable stack shape, reduces product losses and logistics delays, and improves the utilization rate of storage space. In addition, the integration of its precision mechanical structure and advanced control technology provides strong technical support for palletizing operations, realizes efficient, stable, and intelligent palletizing processes, promotes technological progress and industrial upgrading in the field of warehousing and logistics, and lays a solid foundation for improving corporate competitiveness and sustainable development.
