Description

Technical Field

[0001] This utility model belongs to the technical field of production equipment for prefabricated building components made of wood panels, and particularly relates to an automatic pallet feeding and stacking system for prefabricated building components made of wood panels. Background Technology

[0002] In the construction industry, with the rapid development of prefabricated building technology, the requirements for the production efficiency and quality of prefabricated components are increasing. As a new type of building material, non-removable composite formwork has been widely used in prefabricated buildings due to its excellent properties, such as high compressive strength, flexural strength, and impact resistance. Non-removable composite formwork is composed of cement, aggregates, fibers, and steel mesh, and its unique structure makes it outstanding in terms of insulation, decoration, and structural support, making it a core technology in the engineering application technology system of prefabricated non-removable composite formwork insulation and decoration composite systems.

[0003] However, in the production process of non-removable composite formwork, especially on the production line of precast building components, traditional stacking methods rely heavily on manual operation, such as manual stacking and pallet loading / unloading. This method is not only inefficient and labor-intensive, but also makes it difficult to guarantee the accuracy and stability of stacking, easily leading to safety accidents and production delays. In addition, with the expansion of production scale and the increasing demand for automation, traditional manual stacking methods can no longer meet the high-efficiency, precise, and automated production requirements of modern precast building component production lines.

[0004] Although automated palletizing systems have been widely used in other industrial sectors, their direct application is often limited by the unique characteristics and complexity of precast building components, especially panel-type precast components (such as non-removable composite formwork). For example, the varying dimensions, weights, and shapes of panel-type precast components place higher demands on the accuracy, stability, and adaptability of the palletizing system. Furthermore, the spatial layout and process flow of precast component production lines also restrict the direct application of existing automated palletizing systems.

[0005] Therefore, designing an efficient, precise, and automated palletizing system is particularly important for the production of prefabricated panel building components, especially non-removable composite formwork. Such a system can not only improve production efficiency and reduce labor intensity, but also ensure the accuracy and stability of palletizing, providing strong support for the efficient, precise, and automated production of prefabricated buildings.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0029] Please see Figures 1 to 4 An automatic palletizing system for precast building components (such as sheet metal) is disclosed. This system is located adjacent to the non-removable composite template unloading station of the molding machine 7 in the precast building component production line. In this embodiment, the precast building components are illustrated using a non-removable composite template 8 as an example. The system is cleverly integrated into the non-removable composite template unloading station of the molding machine in the precast building component production line, achieving automated and continuous palletizing of the non-removable composite template. Specifically, it includes a frame 1, which forms the skeleton of the entire automatic palletizing system. The frame is equipped with a pallet support frame 2, on which N pallets 9 are stacked, where N is a natural number greater than or equal to 1. This allows for stable support of multiple pallets, improving space utilization and facilitating automated pallet processing. The pallet support frame is connected to the pallet support frame lifting mechanism 3. The pallet support frame lifting mechanism drives the pallet support frame to move up and down, realizing the automated lifting and lowering of pallet stacking. The height of the pallets can be flexibly adjusted according to production needs, improving the adaptability and flexibility of the system. A pallet pushing device 4 is installed at the upper end of the frame. The pallet pushing device moves the first pallet stacked on top of the pallet to the non-removable composite template unloading station one by one, ensuring accurate and fast pallet pushing, reducing manual intervention, improving production efficiency, and ensuring continuous operation of the unloading station. A stacking mechanism 5 is installed above the non-removable composite template unloading station. The stacking mechanism is used to lift or lower the pallet carrying the non-removable composite template, realizing the automated stacking of the non-removable composite template. The lifting or lowering of the pallet is precisely controlled according to production instructions, ensuring the accuracy and stability of stacking, improving product quality and production efficiency.

[0030] More preferably, the pallet support frame lifting mechanism 3 includes screw-nut pairs installed at the four corners of the pallet support frame. The screws 3-10 of the screw-nut pairs are vertically installed on the frame, and the screw nuts 3-11 of the screw-nut pairs are fixedly connected to the pallet support frame 2. A pallet lifting drive unit 3-2, which drives the four screws to rotate synchronously, is installed at the top of the frame. The core of this pallet support frame lifting mechanism 3 lies in the screw-nut pairs installed at the four corners of the pallet support frame. The screws 3-10 are vertically and stably installed on the frame, while the screw nuts 3-11 are fixedly connected to the pallet support frame 2, ensuring the stability and accuracy of the lifting. The pallet lifting drive unit 3-2 equipped at the top of the frame can drive the four screws to rotate synchronously, realizing the smooth lifting and lowering of the pallet support frame and improving the synchronization and reliability of the system.

[0031] More preferably, the pallet lifting drive unit 3-2 includes a pallet lifting drive motor 3-20. The output wheel of the pallet lifting drive motor is connected to two worm gear pairs 3-21 on both sides via a synchronous belt. The worm gear of the worm gear pair is mounted on the lead screw of the lead screw and nut pair, driving the lead screw to rotate and realizing the up-and-down movement of the pallet support frame. Power is provided by the pallet lifting drive motor 3-20, and the output wheel is transmitted to the two worm gear pairs 3-21 on both sides via a synchronous belt. The worm gear is mounted on the lead screw and has a tight fit with the worm, ensuring stable transmission. When the motor starts, the worm drives the worm gear to rotate, which in turn drives the lead screw to rotate, realizing the smooth up-and-down movement of the pallet support frame. This design has a compact structure, high transmission efficiency, and improves the automation and reliability of the system.

[0032] More preferably, the rear side of the pallet support frame is provided with a positioning rod 3-3 that rises or falls with the pallet support frame, and a guide wheel assembly 3-4 is provided on the upper part of the frame corresponding to the positioning rod position. This enhances the stability of the pallet support frame's lifting and lowering, ensures the straightness of the operation, and improves the overall reliability and durability of the system.

[0033] A further preferred embodiment includes a pallet loading mechanism 6 installed at the bottom of the frame, used to transfer a pallet carrying N pallets to the pallet support frame, where N is a natural number greater than or equal to 1. This enables rapid pallet loading, improves production efficiency, reduces manual operation, and ensures the continuity and automation of the production process.

[0034] More preferably, the pallet loading mechanism 6 includes two parallel chain fixing beams 6-1, with a loading chain 6-10 mounted on each beam. One end of each beam has a drive sprocket 6-2, and the drive sprockets on both sides are connected to a synchronous shaft 6-3. Synchronous sprockets 6-4 are mounted on the synchronous shaft, and these sprockets are connected to a pallet loading drive motor 6-6 via a synchronous chain 6-5. When the pallet loading drive motor 6-6 starts, it drives the synchronous sprockets 6-4 to rotate via the synchronous chain 6-5. Since the synchronous sprockets are mounted on the synchronous shaft 6-3, they in turn drive the drive sprockets 6-2 on both sides to rotate synchronously. The drive sprockets are fixed to one end of the chain fixing beams 6-1, driving the chain to move, thereby achieving automatic pallet loading. This design improves loading efficiency and ensures the accuracy and stability of the loading process.

[0035] More preferably, the pallet pushing device 4 includes a pallet pushing frame 4-1, with a pallet pushing plate 4-2 horizontally mounted at the lower end of the frame. The pallet pushing frame is connected to a transfer chain 4-3, which is mounted on a driving transfer sprocket 4-4 and a driven transfer sprocket 4-5. The driving transfer sprocket is connected to a pallet transfer motor 4-6, and the driven transfer sprocket is mounted on a frame 1. When the pallet transfer motor 4-6 starts, it drives the driving transfer sprocket 4-4 to rotate, which in turn drives the driven transfer sprocket 4-5 to rotate synchronously via the transfer chain 4-3. The pallet pushing frame 4-1 connected to the transfer chain 4-3 moves accordingly, and the pallet pushing plate 4-2 at the lower end of the frame pushes the pallets on the pallet to the unloading station one by one. This design achieves automated pallet pushing, improves production efficiency, and ensures the accuracy of the pushing process.

[0036] In a further preferred embodiment, parallel guide rails 4-7 are provided on both sides of the transfer chain, and guide wheel sets 4-8 that cooperate with the guide rails are installed on the pallet pusher frame. This enhances the stability of the push and ensures the straightness and accuracy of the pallet push.

[0037] Further preferably, the palletizing mechanism 5 includes a palletizing lifting frame 5-1, on which a palletizing lifting drive cylinder 5-2 is installed. The palletizing lifting drive cylinder is fixedly installed on a palletizing beam 5-3. The palletizing beam is fixedly connected above the pallet supply station of the frame (the pallet supply station and the non-removable composite template unloading station are at the same location). Palletizing lifting guide columns 5-4 and guide sleeves 5-5 are provided on both sides of the palletizing beam. The lower end of the palletizing lifting guide columns is fixedly connected to the palletizing lifting frame 5-5. A pallet clamping mechanism 5-6 is provided below the palletizing lifting frame. The pallet clamping mechanism is used to lift pallets carrying finished sheet materials. When a pallet carries finished sheet materials, the pallet clamping mechanism 5-6 clamps it, and the pallet lifting drive cylinder 5-2 is activated, lifting the pallet to a designated height for palletizing. This design achieves automated pallet pallet palletizing, improves palletizing efficiency, and ensures the accuracy and stability of palletizing.

[0038] More preferably, the pallet clamping mechanism 5-6 includes pallet clamping beams 5-61 symmetrically hinged to both sides of the pallet lifting frame. The pallet clamping beams are hinged to pallet clamping drive components 5-62. The clamping drive components 7-5-62 are installed on the lower surface of the pallet lifting frame. The pallet clamping drive components can be a motor, gear, or rack. The gear drives the rack as a driving component for forward and backward movement, causing the pallet lifting frame to rotate. Alternatively, it can be a cylinder, with the front end of the cylinder's piston rod serving as the driving end to rotate the pallet lifting frame. In this embodiment, a cylinder is preferred, with the end of the cylinder's piston rod hinged to the pallet lifting frame 5-5. L-shaped brackets 5-63 are provided at both ends of the pallet clamping beams. First, under the action of the pallet clamping drive components, the beams rotate upwards to avoid the pallet, then pass over the pallet and return to their original position. The horizontal part of the L-shaped brackets 5-63 supports the lower surface of the pallet, thereby enabling the lifting or lowering of the finished pallet. The pallet clamping drive component 5-62 drives the pallet clamping beam 5-61 to flip upwards to avoid the pallet. After the pallet enters the correct position, the clamping cylinder resets the clamping beam, and the horizontal part of the L-shaped bracket 5-63 supports the lower surface of the pallet. This design allows for flexible clamping or releasing of the pallet, achieving stable lifting or lowering of finished sheet metal, improving the automation level of the palletizing process, and ensuring the accuracy and efficiency of the palletizing operation.

[0039] In summary, this utility model's automatic palletizing system for prefabricated panel building components, based on a robust frame, achieves automated and continuous palletizing of composite formwork without the need for disassembly through the meticulous design of the pallet support frame, lifting mechanism, pushing device, and palletizing mechanism. The pallet support frame stably stacks pallets, the lifting mechanism flexibly adjusts the height, the pushing device accurately and quickly pushes pallets, and the palletizing mechanism precisely controls the palletizing process.
