摘要

为解决单板旋切生产线中人工分级码垛工作量大、效率低下的问题，设计一种自动分级、码垛的一体化装置。通过分析相邻单板传送特点，设计单板图像全覆盖的采集方法，依据图像中单板覆盖传送带面积大小确定分级依据；结合动作时间确定机械响应距离，以平面四杆机构作为执行端来实现生产线分级、码垛一体化作业，根据旋切原木产生单板的规律确定分级架全部动作次序，Adams运动学仿真结果验证了四杆机构的可行性。

Abstract

In order to solve the issues of heavy workload and low efficiency of manual grading and palletizing processes in the rotary peeling production line, an integrated device of automatic grading and palletizing was designed. Through analyzing the transmitting specification of adjacent veneers, image acquisition methods were designed to ensure full-coverage images of veneers. The classification rules were determined by the area of conveyor belt covered by the veneer in the image. The mechanical response distance was determined based on the action time, and the planar four-bar mechanism was used as the execution end to achieve integrated grading and palletizing processes in the production line. The whole action sequence of the grading frame was determined according to veneer manufacturing principles through peeling logs. The results of Adams kinematics simulation verify the feasibility of the four-bar mechanism.
