背景技术Background technique
林产品、木材工业是中国木材消费重要领域。近年来国内外市场对林产品需求量大增，我国林产品的产量不断增长，其中我国的林产品的产量已名列世界第一，由此也给中国木材供给市场带来了严峻考验，巨大的市场需求需要更强的生产力来满足，同时也要满足更高的质量要求。Forest products and timber industry are important fields of timber consumption in China. In recent years, the demand for forest products in domestic and foreign markets has increased greatly, and the output of forest products in my country has continued to increase. Among them, the output of forest products in my country has ranked first in the world. This has also brought a severe test to China's timber supply market. Huge The market demand of the market requires stronger productivity to meet, but also to meet higher quality requirements.
实际生产过的工序上，木材从砍下，运输到加工厂进行粗加工精加工。木材的形式也从圆木到最后的规整板材，也就是在板材的长宽高（厚度）方面有相应的要求，在板材长度方面，圆木以要求的长度砍下，再进行后续对宽度高度（厚度）加工。通常生产线先粗略的将边皮去除，从侧面看圆木变成近似四边形的矩形方木。通过等间距的多片锯机器，将木材锯切成等高度（等厚度）的板材。此时形成的板材满足等长等厚要求，进一步需要满足宽度的要求。由于此时的木材在宽度截面上看是近似于梯形，在木材的利用率方面，理论上切除梯形的斜边，使木材形成矩形截面是最大化利用木材的一种办法，能有效的降低板材的废品率。In the actual production process, the wood is cut and transported to the processing plant for rough processing and fine processing. The form of wood is also from round logs to the final regular boards, that is, there are corresponding requirements on the length, width and height (thickness) of the boards. In terms of the length of the boards, the round logs are cut at the required length, and then the subsequent width and height are adjusted. (thickness) processing. Usually the production line first roughly removes the edge skin, and the round log becomes a rectangular square log that is approximately quadrilateral when viewed from the side. Saw the wood into boards of equal height (equal thickness) by equidistant multi-blade sawing machines. The plate formed at this time meets the requirements of equal length and equal thickness, and further needs to meet the requirement of width. Since the wood at this time is approximately trapezoidal in terms of width section, in terms of wood utilization, cutting off the hypotenuse of the trapezoid in theory to make the wood form a rectangular cross section is a way to maximize the use of wood, which can effectively reduce the cost of the board. scrap rate.
对此，传统的加工方式为人工对齐，或则采用固定宽度的切割方式。这两种生产方式，一方面不能难以保证产品的加工质量，另一方面板材的利用率下降。一种新型的锯切方式为可调式锯片间距的机器，但相应的需要提供板材的最大锯切宽度数据。对此，就需要一种新型的方法，能保证锯片的下锯是根据木板的最大锯切宽度数据。In this regard, the traditional processing method is manual alignment, or a fixed-width cutting method. These two production methods, on the one hand, cannot guarantee the processing quality of the product, and on the other hand, the utilization rate of the plate decreases. A new type of sawing method is a machine with adjustable saw blade spacing, but correspondingly, the maximum sawing width data of the board needs to be provided. For this, just need a kind of novel method, can guarantee that the down-sawing of saw blade is according to the maximum sawing width data of plank.

所述计算设备根据拟合计算形成锯材侧边边缘线判定锯材两侧沿的最窄位，并在下锯前根据锯材两侧沿最窄位位置对锯片位置进行调整。The calculation device determines the narrowest position of the two sides of the sawn timber according to the edge line formed by the fitting calculation, and adjusts the position of the saw blade according to the narrowest position of the two sides of the sawn timber before sawing.
当需把锯材加工为俯视向呈梯形的整形锯材时，所述光幕传感器在传感器固定架处直线排列为第一光幕阵列101和第二光幕阵列102，第一光幕阵列101、第二光幕阵列102分别设于锯材行进路径的两侧沿上方。When the sawn timber needs to be processed into trapezoidal shaped sawn timber in the top view, the light curtain sensors are arranged in a straight line at the sensor fixing frame as a first light curtain array 101 and a second light curtain array 102, the first light curtain array 101 , The second light curtain array 102 is respectively arranged above the two sides of the sawn timber travel path.

所述第一光幕阵列、第二光幕阵列内的光幕传感器等间距均匀排列。The light curtain sensors in the first light curtain array and the second light curtain array are evenly arranged at equal intervals.
所述第一光幕阵列、第二光幕阵列的发射面之间设有对锯材进行重复扫描的部位，所述对锯材进行重复扫描的部位位于传送带输送面中轴部位上方。Between the emitting surfaces of the first light curtain array and the second light curtain array, there is a position for repeatedly scanning the sawn timber, and the position for repeatedly scanning the sawn timber is located above the central axis of the conveying surface of the conveyor belt.
当需把锯材加工为俯视向呈矩形的整边锯材时，锯片沿与锯材中轴平行向切入锯材；当需把锯材加工为俯视向呈梯形的整边锯材时，锯片沿与锯材中轴成一角度的方向切入锯材。When the sawn timber needs to be processed into rectangular sawn timber with a top view, the saw blade cuts into the sawn timber parallel to the central axis of the sawn timber; when the sawn timber needs to be processed into a trapezoidal full-side sawn timber with a top view, The saw blade cuts into the lumber at an angle to the central axis of the lumber.
本例中的传送带由两个以上的传送带机构水平直线排列组成，光电幕墙设备3设于传送带机构的交界间隔处；光电幕墙设备3两侧的传送带机构的输送速度相同。The conveyor belt in this example is composed of more than two conveyor belt mechanisms arranged horizontally and linearly, and the photoelectric curtain wall equipment 3 is arranged at the junction interval of the conveyor belt mechanisms; the conveyor belt mechanisms on both sides of the photoelectric curtain wall equipment 3 have the same conveying speed.
如图3所示，在将毛边锯材加工成整边锯材之的位置确定时，参照当前毛边锯材的最小宽边尺寸，然后依据各等锯材钝棱百分比进行缩进即为锯切位置。As shown in Figure 3, when determining the position before processing rough-edged sawn timber into whole-edged sawn timber, refer to the minimum wide-side size of the current rough-edged sawn timber, and then indent according to the percentage of blunt edges of each sawn timber, which is sawing Location.
如锯片沿与锯材中轴平行向切入，则可把锯材加工为俯视向呈矩形的整边锯材，如锯片沿与锯材中轴成一角度的方向切入，则可把锯材加工为俯视向呈梯形的整边锯材。If the saw blade cuts in parallel to the central axis of the sawn timber, the sawn timber can be processed into a rectangular full-sided sawn timber in the top view; if the saw blade cuts in a direction at an angle to the central axis of the sawn timber, the sawn timber can be cut It is processed into full-edge sawn timber that is trapezoidal when viewed from above.
当锯片沿与锯材中轴成一角度的方向切入时，毛边锯材亦可加工为俯视向呈梯形的整边锯材；在进行操作之前需对锯材左右两边的不规则形状进行拟合，找出可作为依据进行加工的直线或曲线，使计算设备可依据此直线或曲线来控制锯片切割锯材。When the saw blade cuts in at an angle to the central axis of the sawn timber, the raw-edged sawn timber can also be processed into a trapezoidal whole-edge sawn timber in the top view; the irregular shape of the left and right sides of the sawn timber must be fitted before operation , find out the straight line or curve that can be used as the basis for processing, so that the computing device can control the saw blade to cut the sawn material according to the straight line or curve.

The shapes of the left and right sides of the sawn timber will not be the same. Combined to obtain the processing reference. The sensor can measure the wide-side size of the measured object in real time, and the wide-side size can be set to X; the sensor and the single-chip microcomputer of the computing device communicate with each other for size measurement at regular intervals, so the distance between each measured wide-side size The spacing is fixed, and Y is set as the length of the sawn timber corresponding to the width of the width; the measured data points are shown in Figure 4; after the computing device fits these data points, a processing line or a processing curve is formed as a saw blade The cutting path controls the processing of the saw blade by the saw blade.
上文的拟合中，测得如图4所示的数据点后即可将其拟合成直线。拟采用最小二乘法来进行加工参照直线的拟合。In the above fitting, after the data points shown in Figure 4 are measured, they can be fitted into a straight line. The least square method is proposed to fit the processing reference straight line.
拟合的目的是以给定的N个数据点（xi，yi）为基准在一种函数中找出一个近似函数f（x）。来近似表达这组数据。需要最终得到的近似曲线可以最好的反应数据的走向。曲线拟合就是找出一条曲线让数据点都能够在距离这条曲线的上方或下方的不远处。这样可以体现出数据点的大概分布，而且不会出现小部分比较大的误差。The purpose of fitting is to find an approximate function f(x) in a function based on the given N data points (xi ,yi ). to approximate this set of data. It is necessary that the final approximate curve can best reflect the trend of the data. Curve fitting is to find a curve so that the data points can be not far above or below the curve. In this way, the approximate distribution of data points can be reflected, and there will be no relatively large errors in small parts.
