Description

Technical Field

[0001] This invention relates to the field of automatic packaging line technology for sheet materials, specifically to an automatic packaging line for insulating sheets and its operating method. Background Technology

[0002] With the rapid development of industrial automation and intelligent manufacturing technologies, insulation boards, as key components in electrical and construction fields, have seen their production efficiency, packaging quality, and automation level become core elements of industry competition. In the traditional production process of insulation boards, the palletizing and packaging stages after assembly have long relied heavily on manual labor, leading to numerous problems.

[0003] Firstly, existing insulation board manufacturers generally employ a production model that combines partial automation workstations with manual labor in the downstream packaging process. Specifically, processes such as turning over the boards, stacking, opening and fitting cartons, and placing top covers mainly rely on manual operation. This model has significant drawbacks: during manual board turning, due to the weight and fragility of the insulation boards, improper handling can easily lead to edge damage or surface scratches, resulting in material waste and quality defects. Furthermore, the repetitive, high-intensity labor not only leads to high worker fatigue and low efficiency but also increases the risk of occupational diseases. In addition, the stacking accuracy of manual stacking is difficult to guarantee, potentially causing the stacks to collapse during subsequent transportation or storage, further increasing safety hazards.

[0004] Secondly, insufficient automation in the packaging process also restricts overall production efficiency. In traditional packaging lines, the opening, folding, and stacking of cartons require manual labor. This process is time-consuming and inefficient, especially when order volumes fluctuate significantly, making it difficult for manual operations to meet the demands of flexible production. Furthermore, if film wrapping and strapping operations rely on semi-automated equipment or manual operation, problems such as uneven film tension, non-standard wrapping paths, and inconsistent strapping tightness can easily occur, affecting the aesthetics and protective performance of the finished packaging, leading to increased damage rates during transportation and higher after-sales costs.

[0005] In the existing technology, although some companies have introduced partially automated equipment (such as simple palletizers, single-machine laminating machines, etc.), these devices have the following limitations: 1) The operating range is limited and cannot cover the entire packaging process, still requiring manual coordination between each workstation; 2) The equipment has poor flexibility and is difficult to adapt to the packaging needs of different specifications of boards, resulting in low production line flexibility; 3) There is a lack of integrated control system, poor coordination between devices, and inability to achieve information sharing and process optimization, resulting in limited improvement in production efficiency. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an automated packaging line and method for insulating boards, applicable to automated packaging operations of insulating board assembly lines, pallet stacking, and palletized material stacking. It solves the problems of manual board flipping and stacking, which easily leads to board damage, excessive labor intensity, and low efficiency. Furthermore, it improves the automation level of the production line, thereby increasing production efficiency and ultimately reducing production costs.

[0010] Furthermore, several wooden pallets awaiting destacking are placed on the wooden pallet station. The wooden pallets are destacking by the palletizing robot and then placed on the positioning and conveying station of the palletizing station.

[0011] Furthermore, several bottom cardboard sheets are placed on the bottom cardboard station, and the bottom cardboard sheets are picked up by the palletizing robot and placed on the positioning and conveying station of the palletizing station.

[0012] Furthermore, the board turning station is used to turn the insulation board over. The insulation board is picked up by the palletizing robot and placed on the positioning and conveying station of the palletizing station.

[0013] Furthermore, the cardboard box workstation platform is equipped with cardboard boxes containing several cardboard boxes. The cardboard boxes are opened by the unpacking robot, and then the cardboard boxes are clamped and placed on the box-packing workstation.

[0014] Furthermore, several top cover plates are placed on the top cover plate station, and the top cover plates are placed on the box-setting station by the box-opening robot.

[0015] Furthermore, the palletizing robot has a palletizing robot gripper installed at the front end of its robotic arm; the unpacking robot has an unpacking robot gripper installed at the front end of its robotic arm.

[0021] S4. The incompletely packaged insulation board is transported from the palletizing station to the boxing station on the conveyor.

[0022] S5. Unpacking and repacking of cardboard boxes: After the unpacking robot moves to a suitable position on the robot rail, it first unpacks the cardboard boxes with several cardboard boxes on the cardboard station platform, and then uses the cardboard station platform to clamp and repack the cardboard boxes onto the insulating board in step S3.

[0023] S6. Picking up and fastening the top cover: After the unpacking robot moves to the appropriate position on the robot rail, it picks up the top cover from the top cover station and places it on the insulating board with cardboard skin in step S4.

[0024] S7. Automated Packaging of Material Stacks: The material stacks formed by the boxing steps above are conveyed on a conveyor to the buffer conveying station to wait. They are then conveyed sequentially through a through-type laminating machine, a rocker arm wrapping machine, and a through-arrow type strapping machine to complete the top laminating of the material stack, the film wrapping of the pallet material stack, and the strapping of the pallet material stack.
