Intelligent deflection-adjustable wood-based panel vertical and horizontal sawing production line and method

Abstract

The invention relates to an intelligent deviation adjusting type artificial board longitudinal and transverse edge trimming production line and a method. The production line comprises a board edge visual identification system 2, a board transverse deviation adjusting system 3, a conveying mechanism 4, a board longitudinal edge trimming system 5, a conveying mechanism 6, a board longitudinal centering mechanism 7, a board transverse edge trimming system 8 and a stacking mechanism 9. The deviation adjusting method comprises the following steps: adopting the board edge visual identification system 2 to collect and extract the transverse edge and longitudinal edge outlines of the board and the breadth flaw feature image information; calculating the finished board dimension and the offset and the offset direction of an artificial board; transferring the offset and the offset direction to the board transverse deviation adjusting system 3, adopting a servo motor 31 to drive a deviation adjusting sliding table 35 to move to realize automatic deviation adjustment of the board; and comparing the dimension of the finished board with the specification of a standard board, calculating intervals between longitudinal saws and between transverse saws, and automatically adjusting the intervals of saw blades of the board longitudinal edge trimming system 5 and the board transverse edge trimming system 8, thus realizing self-adaption of wide board cutting.

[0002] Due to the rapid development of my country's economy and the increasing living standards of residents, people have higher requirements for the material, size and shape accuracy of the parts. In order to improve the utilization rate of wood, multi-layer boards such as three-ply boards and five-ply boards are often used. Multi-layer boards are usually used as materials for aircraft, ships, trains, automobiles, construction and packaging crates. my country's wood product output accounts for a large proportion in the world, and the total output of furniture and wood-based panels is also among the best. Wood product processing equipment, especially multi-layer board processing equipment, has a relatively low degree of automation, and it is difficult for wood-based panel processing equipment to adapt to the rapid growth of my country's wood-based panel industry.

Saw edge is an important process of wood-based panel processing, while the longitudinal and horizontal sawing of panels in my country is mostly completed by manual operation or simple devices, with low degree of digital control, low processing speed, high labor intensity for operators, poor working environment, and high operation risk. At the same time, labor costs are getting higher and higher, which is not conducive to the further development of enterprises.

In order to improve the automation of wood-based panel processing equipment, many wood-based panel processing companies have developed a variety of wood-based panel vertical and horizontal sawing equipment according to the wood-based panel processing technology, such as patent number: ZL201110227965.0 "A CNC automatic vertical and horizontal sawing machine for wood-based panels", etc. , but in the sawing process, the outer contour of the man-made board is often used for centering, and the board is usually produced by a paving slab through a hot pressing process. In the paving slab, multiple veneers (or veneers) are superimposed on each other As a result, the edge of the slab is uneven. The traditional centering device only performs centering and cutting according to the shape of the slab. When the slab is irregular or the surface of the slab is defective, it is very easy to produce waste products. Problem, the present invention introduces machine vision technology into plate edge recognition, uses machine vision to detect the edge of the plate to form an optimal cutting plan, and drives the feeding system to realize automatic deviation adjustment of the slab, improve the cutting quality of the plate, and reduce the scrap rate
