Problems solved by technology

[0003] At present, in order to meet the requirements of consumers for color, wood processing manufacturers generally use manual methods for wood sorting. This manual sorting method has some unavoidable defects, that is, low efficiency and excessive chance. The quality of the sorting is unstable, and the workers repeat high-intensity work every day. It is impossible to ask them to make accurate judgments on each piece of wood. The longer the working hours, the more accidental the degree It is very likely that the quality of the product will decline due to one or two negligence, resulting in the loss of the economy and reputation of the enterprise.

Embodiment 1

[0020] Embodiment 1: a kind of method of sorting timber according to color and grain, it comprises the following steps:

[0021] a) Create category data: According to the factors of wood color, wood grain inclination angle and color spot ratio, create a category data of wood images to be classified. The color factor distinguishes three levels of color difference, and selects three representative wood samples and calibrates them with a video imaging device. The calibration colors are: FF9900 (R=255, G=153, B=0), F8CC34 (R=248, G = 204, B = 52), E3CF63 (R = 227, G = 207, B = 99); the inclination angle of wood grain is divided into two levels, the inclination angle is less than or equal to 5° for straight grain, and the angle is greater than 5° for twill grain; The factor of spot ratio is divided into three levels, the proportion of stain (wood grain color) is less than or equal to 1% of the board surface, the proportion of stain is 1-10% of the board surface, and the proportion ...

Embodiment 2

[0032] Embodiment 2: as figure 1 As shown, a device for sorting wood according to color and wood grain, it includes a wood conveyor belt 1, a wood video imaging device 2, several wood sorting devices 3 and a program control system, and the video imaging device 2 is installed at the beginning of the wood conveyor belt 1 At the end, a number of wood sorting devices 3 are equidistantly installed on the side of the wood conveyor belt 1 downstream of the video imaging device 2, and the video imaging device 2 and a number of wood sorting devices 3 are respectively connected to the program control system circuit. Such as figure 2 Shown, described video imaging device 2, it comprises a base 21, and a door font frame 22 is installed on one side of base 21, slideway 24 is arranged on the two columns of frame 22, and a shading cover 29 is slidably installed on the slideway 24 Lighting lamp 28 is installed on the inside of hood 29, a support 27 is fixed above the hood 29, a camera 26 is...

Abstract

The invention discloses a method and a device for sorting wood according to colors and wood grains. The method comprises the following steps of: establishing categorical data, collecting wood images, confirming wood categories, starting sorting devices, and the like. The device comprises a wood conveying belt, a wood video imaging device, a plurality of wood sorting devices and a program control system, wherein the video imaging device is arranged at the beginning end of the wood conveying belt, the plurality of wood sorting device are arranged at the lateral side of the wood conveying belt at the downstream of the video imaging device in an equidistance way, and the video imaging device and the plurality of wood sorting devices are respectively in circuit connection with the program control system. The invention has accurate sorting and high working efficiency and avoids the individual difference and the inconsistency of manual sorting.

Description

technical field [0001] The invention belongs to the technical field of industrial automatic detection, in particular to a method for sorting wood according to color and wood grain, and meanwhile, the invention also relates to equipment for realizing the method. Background technique [0002] In wood processing and production, in order to ensure product quality, it is necessary to sort wood according to its color and wood grain. This is because wood is a natural material. The same tree, the same tree, and different parts have different materials and colors. However, people have higher requirements for wooden products, and the consistency of color and texture is the most basic requirement. [0003] At present, in order to meet the requirements of consumers for color, wood processing manufacturers generally use manual methods for wood sorting. This manual sorting method has some unavoidable defects, that is, low efficiency and excessive chance. The quality of the sorting is uns...
