Description

Technical Field

[0001] The invention relates to the technical field of conveying in wood board workshops, and in particular 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 making. Different types of wood boards vary in performance, price and environmental friendliness.

[0003] The processing of furniture wood panels involves multiple steps, from raw material processing to finished product assembly. The processing procedures for different types of wood (such as solid wood, plywood, and MDF) vary. The main processes for furniture wood panel processing include raw material processing, cutting and slitting, planing and sanding, splicing and gluing, edge banding, surface finishing, drilling and grooving, etc. Surface finishing specifically encompasses various processes, including veneer application, painting, lamination, and UV curing.

[0004] In the field of wood processing (especially the furniture manufacturing industry), traditional production processes have long faced the following technical pain points:

[0005] 1. Process Discreteness: Core processes such as veneering, edge banding, and flipping rely on independent equipment and manual handling. This results in: long material stagnation time between processes (accounting for more than 40% of the overall processing cycle); loose equipment layout, and space utilization rate of less than 50%; frequent manual intervention, and single board processing requires 6-8 manual operations.

[0006] 2. Inefficiency of double-sided processing: Manual flipping of wooden boards is inefficient (time taken per time > 45 seconds) and easily damages the surface (defective rate > 5%). The existing mechanical flipping mechanism has poor adaptability and is not compatible with boards of different sizes (adjustment time accounts for 30% of the total flipping time).

[0007] 3. Edge banding accuracy bottleneck: Multi-edge banding requires multiple positioning adjustments, with cumulative positioning errors greater than 2mm; traditional conveying systems cannot dynamically compensate for sheet offset (long-distance conveying offset greater than 5mm)

[0008] 4. Conflict between safety and quality: Manual handling leads to a safety accident rate of >1.2‰; differences in operator skills cause quality fluctuations of up to ±1.5mm.

[0009] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0010] In response to the defects in the existing technology, the present invention provides a transfer and conveying system for edge banding and resurfacing of wooden boards, which is used to solve the long-standing problems of discrete processes, manual operations, low positioning precision and fragmented layout during the processing and transportation of wooden boards in furniture manufacturing workshops in traditional technologies.

Dynamic positioning compensation technology: The oblique conveying rollers and the second mounting frame in the present invention form a self-alignment system, which can automatically correct the offset of the plate during the conveying process; the guide wheels can realize dynamic calibration of the conveying path to ensure a processing positioning accuracy of ±0.3mm.

[0054] 5. Modular production layout optimization; the transfer distribution component can coordinate the continuous transfer of panels between various workstations, and the edge banding conveyor component and the rotary conveyor component cooperate to form a circular production line, which reduces the equipment footprint by 40% while increasing the theoretical production capacity to three times that of traditional production lines.
