Description

Technical Field

[0001] This utility model relates to the field of palletizing machine technology, specifically a high-efficiency high-position palletizing machine. Background Technology

[0002] A high-level palletizer is an automated mechanical device that can automatically complete the stacking, packaging, and palletizing of products at a high position. It is designed for high-level scenarios such as the end of the production line or above the warehouse. It can efficiently complete the automatic stacking and palletizing of bagged, boxed, and other materials, and is widely used in the food, chemical, and pharmaceutical industries.

[0003] When existing high-efficiency high-position palletizing machines are in use, the goods they grab are placed directly on the storage pallet while suspended in mid-air. As the goods fall onto the storage pallet, stacking deviations may occur, making it difficult to form stable support and causing tilting. When subsequent goods are stacked, the instability is further amplified, increasing the risk of tipping over and ultimately causing the entire stack of goods to tip over. Utility Model Content

[0013] 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.

[0014] Please see Figure 1-3A high-efficiency high-level palletizer includes a vertical frame 1, a bracket 2 for placing pallets that can be raised and lowered on the vertical frame 1, a movable frame 3 that can be limited and moved on the top of the vertical frame 1, a material clamping mechanism 4 that can be limited and moved on the movable frame 3, a limiting mechanism for limiting the material during the palletizing process on the vertical frame 1, the limiting mechanism including multiple sets of adjustable baffles, and multiple sets of pallet conveying rollers that can be rotatably arranged on the bracket 2. The vertical frame 1 is the core support structure of the entire palletizer, providing installation benchmarks and stable support for all components such as the bracket 2, moving frame 3, limiting mechanism, and housing 5. This ensures the overall structural stability of the equipment during high-level palletizing operations, bearing the weight of the bracket 2, the pallet, and the palletized goods. It also provides reasonable installation space and movement guidance for various moving parts (such as the movement of the moving frame 3 and the extension / retraction of the hydraulic telescopic rod 9). The core function of the bracket 2 is to support the pallet. Its height-adjustable design adapts to different palletizing height requirements, gradually lowering as the number of layers of goods increases during palletizing to ensure that each piece of goods is placed at a reasonable working height. Its rotatable multiple pallet conveyor rollers facilitate convenient pallet placement and removal after palletizing, reducing manual intervention during pallet handling and improving operational efficiency. To provide a stable bearing base for the pallet, the movable frame 3 is installed on the top of the vertical frame 1 and can move along a preset trajectory. Its core function is to drive the material gripping mechanism 4 to flexibly switch between the "goods gripping area" and the "palletizing area". Through precise horizontal movement and positioning, it transfers the gripped goods to the pallet on the bracket 2, providing a prerequisite for the accurate stacking of subsequent goods. It is a key component for realizing cross-area transfer of goods. The material gripping mechanism 4 directly performs the gripping and releasing actions of the goods and is the core execution component for realizing the transfer of goods. By adapting to different goods shapes with clamps (such as claws), it stably grips the goods on the conveyor line. With the movement of the movable frame 3 and its own posture adjustment, it transfers the goods to the palletizing position. Finally, it completes the stacking of goods through precise release. Its gripping stability directly affects the neatness of the subsequent stacking.

[0015] Please see Figure 2 and Figure 3 The baffle plate includes a first baffle 10 and two sets of second baffles 12. The two sets of second baffles 12 are detachably mounted on the first baffle 10. The first baffle 10 is provided with a plurality of first connecting holes 11, and the second baffle 12 is provided with a plurality of second connecting holes 13 that cooperate with the first connecting holes 11. The first baffle 10 and the second baffle 12 are detachable, allowing for selection of installation based on the cargo shape and adjustment of their position after installation. This forms a multi-directional enclosure, limiting the cargo from multiple sides and constraining its offset space. Position adjustment in the vertical direction (driven by lead screw 6) and the horizontal direction (driven by hydraulic telescopic rod 9) allows them to conform to the sides of the cargo, restricting horizontal displacement and tilting during stacking. Especially during cargo descent, they prevent tilting caused by posture shifts, reducing the risk of tipping. The core function of the first connecting hole 11 and the second connecting hole 13 is to enable the detachable installation and position adjustment of the second baffle 12. Bolts and other connecting parts pass through the two sets of connecting holes, fixing the second baffle 12 to the preset position of the first baffle 10. The design of multiple sets of connecting holes allows for flexible adjustment of the installation spacing, ensuring the limiting mechanism can adapt to cargo of different sizes, achieving flexible adaptation of the limiting range, meeting the stacking limiting requirements of different specifications of cargo, and improving the equipment's versatility.

[0016] Please see Figure 2 and Figure 3 The vertical frame 1 is provided with multiple sets of housings 5. The top of the housing 5 is rotatably provided with two sets of lead screws 6 that can cooperate with each other. Lead screw nuts 7 are engaged on lead screws 6. The outside of lead screw nuts 7 is provided with a mounting bracket 8. The mounting bracket 8 is provided with multiple sets of hydraulic telescopic rods 9 that can cooperate with each other. The first baffle 10 is fixedly provided at the output end of the hydraulic telescopic rod 9. The bottom end of lead screw 6 is provided with a gear 14. The inside of the housing 5 is rotatably provided with a rotating rod 15. The outside of the rotating rod 15 is fixedly provided with multiple sets of gears 16 that mesh with gear 14. The housing 5 is also provided with a drive motor 17, and the output end of the drive motor 17 is fixedly connected to one end of the rotating rod 15. The housing 5 serves as the mounting and protective carrier for the limiting mechanism. Internally, it houses transmission components such as the rotating rod 15, gear 14, and gear 16. Externally, it provides a fixed mounting surface for the lead screw 6 and drive motor 17. Its core function is to protect the internal transmission components from dust, external impacts, and other harmful substances, extending their service life. It also ensures the coaxiality and fit accuracy of the transmission components, guaranteeing the stability of power transmission. The lead screw 6 and lead screw nut 7 form a helical transmission mechanism, the core transmission component for adjusting the horizontal position of the first baffle 10. Driven by the drive motor 17, the rotation of the lead screw 6 converts the rotational motion into the linear motion of the lead screw nut 7, thereby driving the mounting frame 8 and the first baffle 10 to move vertically, achieving precise adjustment of the baffle position and adapting to the height limiting requirements of different goods. The mounting frame 8 serves as a component connection and load-bearing structure. One end is fixed to the lead screw nut 7, and the other end is fitted with a hydraulic telescopic rod 9 and the first baffle 10. It acts as an intermediate carrier connecting the transmission component (lead screw nut 7) and the actuator (first baffle 10). The integration of frame 8 combines the horizontal power of the screw drive with the telescopic power of the hydraulic telescopic rod 9 to achieve the horizontal and vertical position adjustment of the first baffle 10. It also provides stable installation support for the first baffle 10, preventing it from wobbling during the limiting process. The two ends of the rotating rod 15 are rotatably connected to the housing 5, and multiple sets of gears 16 are externally fixed. When the drive motor 17 drives the rotating rod 15 to rotate, the corresponding gears 14 and screw 6 can be driven simultaneously through the multiple sets of gears 16, ensuring that the first baffles 10 on both sides or multiple sides can move synchronously and symmetrically, avoiding imbalance of force on the goods due to uneven movement on one side. The drive motor 17 provides the power source for the vertical position adjustment of the limiting mechanism. Its core function is to drive the rotating rod 15 to rotate. Through the forward and reverse rotation control of the motor, the rotating rod 15, gears 16, 14, and screw 6 are driven sequentially, ultimately achieving the vertical lifting and lowering adjustment of the first baffle 10. Furthermore, the motor's speed and angle can be precisely controlled by the control system to ensure the position adjustment accuracy of the first baffle 10, adapting to the limiting requirements of goods of different specifications.

[0017] Working principle: The vertical frame 1 serves as the core support foundation, providing a stable installation benchmark for all components. Before operation, the pallet is conveyed into position via multiple sets of rotatable pallet conveyor rollers on the bracket 2. The bracket 2 is initially positioned at the starting height suitable for stacking goods, waiting to receive the goods. Simultaneously, workers can adjust the installation positions of the two sets of second baffles 12 on the first baffle 10 using the first connecting hole 11 on the first baffle 10 and the second connecting hole 13 on the second baffle 12, based on the size and shape of the goods to be stacked, completing the initial adaptation of the limiting mechanism. The movable frame 3 at the top of the vertical frame 1 moves along a preset trajectory, driving the material gripping mechanism 4 to move to the goods gripping area. After the material gripping mechanism 4 stably grips the goods on the conveyor line using the grippers adapted to the goods, the movable frame 3 starts again, accurately transferring the material gripping mechanism 4 to directly above the pallet on the bracket 2, accurately positioning the goods for stacking. After the drive motor 17 starts, its output end drives the rotating rod 15 inside the housing 5 to rotate. Multiple sets of gears outside the rotating rod 15 rotate... 16 rotates synchronously, and through meshing with the gear 14 at the bottom of the lead screw 6, drives the two sets of lead screws 6 at the top of the housing 5 to rotate. When the lead screw 6 rotates, it converts the rotational motion into the linear motion of the lead screw nut 7, which in turn drives the mounting bracket 8 outside the lead screw nut 7 to move vertically. The hydraulic telescopic rod 9 on the mounting bracket 8 adjusts its vertical height accordingly. Then, the hydraulic telescopic rod 9 starts to extend and retract, driving the first baffle 10 fixed at its output end to adjust its horizontal position. Finally, the first baffle 10 and the second baffle 12 form a closed-type limiting structure that fits the side of the goods. The material clamping mechanism 4 accurately releases the goods. During the falling process, the goods are prevented from tilting or deviating due to the limiting effect of the first baffle 10 and the second baffle 12, and they land smoothly on the pallet. As the number of layers of goods increases, the bracket 2 gradually descends, always keeping the goods stacked at a reasonable working height. When a stack of goods is completed, the pallet conveying roller on the bracket 2 easily removes the pallet full of goods. Then, a new empty pallet enters through the conveying roller, and the equipment enters the next round of stacking cycle.
