Description

Technical Field

[0001] The present invention relates to the technical field of wood board conveying, and particularly to a transfer conveying system for edge banding and face changing of wood boards. Background Art

[0002] Wood boards are commonly used materials in furniture manufacturing. Different types of wood boards vary in performance, price, and environmental friendliness.

[0003] The processing technology of furniture wood boards involves multiple links, from raw material processing to finished product assembly. The processing processes of different wood boards (such as solid wood, plywood, fiberboard, etc.) also vary. The processing technology of furniture wood boards mainly includes: raw material processing, cutting and blanking, planing and sanding, splicing and gluing, edge banding treatment, surface decoration treatment, drilling and grooving, etc. Specifically for the surface decoration treatment of wood boards, it also includes various processes such as veneering, paint spraying, laminating / UV curing, etc.

[0004] In the field of wood board processing (especially in the furniture manufacturing industry), the traditional production process has long faced the following technical pain points: 1. Process discretization: Core processes such as veneering, edge banding, and flipping rely on independent equipment and manual handling for connection, resulting in: long material stagnation time between processes (accounting for more than 40% of the overall processing cycle); loose equipment layout, with space utilization rate less than 50%; frequent manual intervention, and 6 - 8 manual operations are required for single board processing.

[0005] 2. Inefficiency in double - sided processing: Manual flipping of wood boards is inefficient (single - time consumption > 45 seconds) and easily damages the surface (defect rate > 5%); the existing mechanical flipping mechanism has poor adaptability and cannot be compatible with different - sized boards (adjustment time accounts for 30% of the total flipping time).

[0006] 3. Bottleneck in edge banding accuracy: Multiple positioning adjustments are required for multi - side edge banding, and the cumulative positioning error > 2mm; the traditional conveying system cannot dynamically compensate for the offset of the board (offset amount > 5mm during long - distance conveying). 4. Conflict between safety and quality: Manual handling leads to a safety accident rate > 1.2‰; quality fluctuations caused by differences in operator skills reach ±1.5mm.

[0007] In summary, it can be seen that the existing technology is obviously inconvenient and defective in actual use, so it is necessary to improve. Summary of the Invention

[0008] Aiming at the defects in the existing technology, the present invention provides a transfer conveying system for edge banding and face changing of wood boards to solve the problems of long - term process discretization, manual operation, low positioning accuracy, and fragmented layout that exist in the processing and conveying of furniture - making wood boards in the workshop in traditional technology.
