Description

Technical Field

[0001] This utility model relates to the field of packaging bag palletizing technology, specifically a high-position palletizing combined push-bag mechanism. Background Technology

[0002] In modern logistics, warehousing, and production sectors such as chemicals and food, automated palletizing of bagged materials (such as fertilizers, feed, cement, and grains) is a key step in improving production efficiency and reducing labor intensity. High-level palletizers are widely used due to their high stacking capacity and efficient space utilization. The bag-pushing mechanism, as the core actuator of the high-level palletizer, directly affects the overall operating efficiency and stability of the machine.

[0003] Currently, most bag-stacking pallets on the market are rectangular boards, suitable for the common 2+3 stack layout, and perform well. However, they have strict requirements on the stacking pattern. For special stack layouts, especially the U-shaped stack layout, they cannot guarantee the pushing effect, and bags often become crooked during use.

[0004] Therefore, there is an urgent need for a high-level palletizing and pushing mechanism that can adapt to different pushing needs, has a stable and reliable structure, and is easy to maintain. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a high-level palletizing combined pusher mechanism, which has the advantages of flexible and adaptable pushing, stable structure and reasonable force distribution, and efficient and reliable power transmission. It solves the problems of traditional single pusher mechanisms being unable to flexibly adapt to changes in the number and arrangement width of different material bags, resulting in poor equipment versatility. Traditional pusher mechanisms are also prone to pusher deformation and mechanism jamming under long-term high-load operation due to unreasonable structural design, resulting in low reliability, short lifespan, and energy waste when pushing all materials with a single drive.

[0006] (II) Technical Solution To achieve the aforementioned goals of flexible and adaptable pushing, stable structure and reasonable force distribution, and efficient and reliable power transmission, this utility model provides the following technical solution: a high-level palletizing combined pusher mechanism, including a main crossbeam and mounting plates disposed at both ends of the main crossbeam, a supporting crossbeam disposed between the two mounting plates, and the supporting crossbeam disposed on one side of the main crossbeam, a driving mechanism disposed on the upper side of the supporting crossbeam, and the output end of the driving mechanism disposed on the lower side of the main crossbeam, a bottom crossbeam disposed at the bottom of one side of the mounting plate, and a pusher plate disposed on the outer side of the bottom crossbeam, the pusher plate being connected to the driving mechanism.

[0007] Preferably, the push plate includes a first push plate, a second push plate, and a third push plate, and the first push plate, the second push plate, and the third push plate are respectively installed on the outer side of the bottom crossbeam, and the first push plate, the second push plate, and the third push plate are respectively connected to the corresponding drive mechanism.

[0008] Preferably, the bottom crossbeam has three sets of mounting seats installed inside, and each set of mounting seats has two mounting seats. The mounting seats have a rotating shaft connected inside, and a pull rod is fixedly installed in the middle of the rotating shaft. A push rod is fixedly installed at one end of the pull rod, and the pull rod and the push rod are arranged in an L-shape. The first push plate, the second push plate and the third push plate are respectively installed on one side of the pull rod at the corresponding position.

[0009] Preferably, the drive mechanism includes three sets of pneumatic cylinders mounted on the upper side of the support beam, with the output end of the pneumatic cylinder facing downwards. The output end of the pneumatic cylinder is provided with a connector, and the connector is rotatably connected to one side of the pull rod. A connecting shaft is mounted on one side of the pull rod, and the connector is mounted on one end of the connecting shaft.

[0010] Preferably, three sets of fixing seats are installed on the upper side of the supporting beam, and fixing rings are installed inside the fixing seats, with the pneumatic cylinder fixedly installed inside the fixing rings.

[0011] (III) Beneficial Effects Compared with existing technologies, this utility model provides a high-level palletizing combined pusher mechanism with the following advantages: This high-level palletizing combined pusher mechanism, by setting three independent pusher units—a first pusher plate, a second pusher plate, and a third pusher plate—each controlled by a corresponding drive mechanism, can achieve zoned and time-based pushing. It can flexibly handle material bags of different quantities and arrangement widths, improving the equipment's versatility and adaptability. When pushing a small amount of material, only some pushers can be activated, resulting in energy efficiency. A stable frame structure composed of a main crossbeam, a support crossbeam, and a bottom crossbeam provides high overall rigidity. Each pusher plate transmits power through an L-shaped pull rod and push rod structure, efficiently converting the vertical force generated by the drive mechanism into a horizontal pushing force. The force transmission path is clear, the mechanism operates smoothly, effectively avoiding deformation and jamming of the pusher plate under high torque, and extending the equipment's service life. The drive mechanism (pneumatic cylinder) is mounted on the support crossbeam through a fixed seat and a fixed ring, and is rotatably connected to the pusher unit through a connector and a connecting shaft. This modular design allows the drive unit and push plate unit to be disassembled and replaced independently, greatly facilitating daily maintenance, repair, and component replacement, and significantly reducing maintenance costs and downtime. Utilizing the lever principle formed by the rotating shaft, pull rod, and push rod, the linear motion of the pneumatic cylinder is converted into the horizontal linear motion of the push plate. The structure is simple and compact, with high transmission efficiency and fast response, ensuring accurate and powerful bag-pushing action. Attached Figure Description

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Please refer to Figure 1-5A high-level palletizing combined push-pack mechanism includes a main crossbeam 1 and mounting plates 2 disposed at both ends of the main crossbeam 1. A supporting crossbeam 3 is provided between the two mounting plates 2, and the supporting crossbeam 3 is located on one side of the main crossbeam 1. A drive mechanism is provided on the upper side of the supporting crossbeam 3, and the output end of the drive mechanism is located on the lower side of the main crossbeam 1. A bottom crossbeam 4 is provided at the bottom of one side of the mounting plate 2, and a push plate is provided on the outer side of the bottom crossbeam 4. The push plate is connected to the drive mechanism. The push plate includes a first push plate 8, a second push plate 9, and a third push plate 10, and the first push plate 8, the second push plate 9, and the third push plate 10 are respectively installed on the outer side of the bottom crossbeam 4. The first push plate 8, the second push plate 9, and the third push plate 10 are respectively connected to the corresponding drive mechanism. The bottom crossbeam 4 has three sets of mounting seats 13 installed inside, with two mounting seats 13 in each set. Each mounting seat 13 has a rotatably connected shaft 14 inside, and a pull rod 12 is fixedly mounted in the middle of the shaft 14. A push rod 11 is fixedly mounted at one end of the pull rod 12, and the pull rod 12 and push rod 11 are arranged in an L-shape. A first push plate 8, a second push plate 9, and a third push plate 10 are respectively installed on one side of the pull rod 12 at corresponding positions. The drive mechanism includes three sets of pneumatic cylinders 7 installed on the upper side of the support crossbeam 3, with the output end of each pneumatic cylinder 7 facing downwards. A connector 15 is provided at the output end of each pneumatic cylinder 7, and the connector 15 is rotatably connected to one side of the pull rod 12. A connecting shaft 16 is installed on one side of the pull rod 12, and the connector 15 is installed at one end of the connecting shaft 16. Three sets of fixed seats 5 are installed on the upper side of the support crossbeam 3, and a fixing ring 6 is installed inside each fixed seat 5. The pneumatic cylinder 7 is fixedly installed inside the fixing ring 6.

[0016] The main crossbeam 1, serving as the "backbone" of the entire mechanism, is the primary load-bearing and stress-bearing component. It bears all the reaction forces and torques generated by the drive mechanism and the pushing process. It is typically made of high-strength rectangular steel tubing or I-beams, and may have internal reinforcing ribs to ensure its bending and torsional rigidity. Its length determines the maximum pushing width that the mechanism can cover. The mounting plate 2 is a crucial component connecting the main crossbeam 1 to the palletizer's main frame. It also serves as the mounting reference for supporting the crossbeams 3 and 4. Made of thick steel plate, it is precision-machined to ensure accurate mounting hole positions. There are usually two plates, located at both ends of the main crossbeam, forming the foundation of the entire mechanism.

[0017] The support beam 3 is specifically designed for mounting and securing the drive mechanism. Arranged parallel to the main beam 1, it also needs sufficient rigidity to withstand the vibrations and reaction forces generated by the pneumatic cylinder 7 during operation. Together with the main beam 1, it forms a stable "double-layer" frame, separating the drive layer from the execution layer, resulting in a clear structure. The bottom beam 4 serves as the mounting base and motion guide for the push plate and its transmission mechanism. It is typically a long, rectangular box structure with a hollow interior to accommodate the transmission components. Its sides are equipped with long, narrow guide grooves, allowing the push plate to smoothly perform linear reciprocating motion. The bottom beam directly faces the palletizing platform and requires good wear resistance.

[0018] Pneumatic cylinder 7 is chosen as the power source because of its fast operation, cleanliness, and relatively low cost, making it ideal for fast-paced palletizing scenarios. Three sets of pneumatic cylinders correspond one-to-one with three sets of push plates, achieving independent drive. The fixed base 5 and fixed ring 6 form a "clamping" installation structure, allowing for easy adjustment and locking of the pneumatic cylinders while effectively absorbing shocks and vibrations during operation. Connector 15 and connecting shaft 16 form a crucial "moving joint." One end of connector 15 (fisheye connector) is connected to the piston rod of the pneumatic cylinder, and the other end forms a rotating pair with the pull rod 12 via the connecting shaft 16. This design allows the pneumatic cylinder to adapt to the angle changes of the pull rod 12 during vertical movement, avoiding the jamming phenomenon of rigid connections and ensuring smooth power transmission.

[0019] Working principle: All pneumatic cylinders 7 are in the retracted state, and the push plates (8,9,10) are in the initial position. The three sets of pneumatic cylinders 7 extend simultaneously, and the piston rod moves downward. The piston rod pulls the pull rod 12 downward through the connector 15 and the connecting shaft 16. The pull rod 12 drives the rotating shaft 14 to rotate in the mounting base 13. The rotation of the rotating shaft 14 causes the push rod 11 fixed to it to swing forward, thereby strongly pushing the first, second, and third push plates (8,9,10) to move horizontally forward, pushing the entire row of material bags to the designated stack position. After the pushing action is completed, the pneumatic cylinder (7) retracts, and by pulling the pull rod 12 in the opposite direction, the push rod 11 drives the push plate back to the initial position, waiting for the next work cycle.

[0020] like Figure 4 and Figure 5In the U-shaped stacking method, the bags are conveyed in a prescribed order. After bags 1 and 2 arrive at the pusher, the first pusher plate 1, the second pusher plate 2, and the third pusher plate 3 fall and advance to the working position. Then, the first pusher plate 1 is raised, and the second pusher plate 2 and the third pusher plate 3 continue to push until the side of bag 2 is flush with the tail of bag 1. Then, the second pusher plate 2 and the third pusher plate 3 are raised, and the entire pusher plate returns to its initial position. At this point, after bags 3 and 4 arrive at the pusher, the first pusher plate 1, the second pusher plate 2, and the third pusher plate 3 fall and advance to the working position. Then, the first pusher plate 1, the second pusher plate 2, and the third pusher plate 3 are raised, and the entire pusher plate returns to its initial position. The second layer then begins to be pushed, with its stacking direction opposite to the first layer. After bags 1 and 2 reach the pusher, the first pusher plate 1, the second pusher plate 2, and the third pusher plate 3 fall down and advance to the working position. Then, the third pusher plate 3 rises, and the first pusher plate 1 and the second pusher plate 2 continue to push until the side of bag 1 is flush with the tail of bag 2. At this point, the first pusher plate 1 and the second pusher plate 2 rise up, and the entire pusher plate returns to its initial position. Then, after bags 3 and 4 reach the pusher, the first pusher plate 1, the second pusher plate 2, and the third pusher plate 3 fall down and advance to the working position. Then, the first pusher plate 1, the second pusher plate 2, and the third pusher plate 3 rise up, and the entire pusher plate returns to its initial position. This process is repeated until the entire stack is completed.
