Problems solved by technology

[0004] Aiming at the problems that the existing wood size inspection requires manual measurement, the labor intensity of the workers is relatively high, and the space requirement for the measurement site is relatively large, the present invention provides a log measuring device, which can measure both sides of the log when the log is in a stacking state. The diameter and length of the end face are automatically scanned and measured in batches, and the entire log pile is quickly scanned by the moving scanning of the measuring mechanism, so as to calculate the shape data of the log, which not only reduces the work intensity of the workers, but also saves the measurement space

Embodiment 1

[0041] This embodiment provides a log measuring device, such as figure 1 As shown, it includes a moving mechanism 3 , a frame 1 and a measuring mechanism 2 ; the moving mechanism 3 is installed at the bottom of the frame 1 . The measuring mechanism 2 is installed on the rack 1, and the moving mechanism 3 drives the rack 1 to move along the stacking direction of the log stack so that the measuring mechanism 2 scans the entire log stack, and the measuring mechanism 2 measures the log stack from the outside of the log stack.

[0042] The measuring mechanism 2 collects the shape information of each log in the log stack from the outside to the inside from multiple directions. Specifically, the measuring mechanism 2 at least includes an end face measurement sub-mechanism for collecting the end face data of the logs, and may also include a log for collecting the log. A top surface measurement sub-mechanism for the top surface and / or a lidar 22 for acquiring 3D shape data of the log s...

Abstract

The invention discloses a log measuring device which comprises a rack, a measuring mechanism and a moving mechanism. The measuring mechanism is used for collecting shape data of logs; the moving mechanism is used for enabling the rack to move; the measuring mechanism and the moving mechanism are mounted on the rack; the moving mechanism drives the rack to move in the stacking direction of the log pile so that the measuring structure can scan and measure the whole log pile. The measuring mechanism comprises an end face measuring sub-mechanism used for collecting end face data of the log and a top face measuring sub-mechanism used for collecting the top face of the log. According to the invention, measurement of the logs can be realized, the logs do not need to be arranged dispersedly, and acquisition and calculation of shape data can be completed in a log stacking state.

Description

technical field [0001] The invention belongs to the technical field of dimension measurement, and more particularly relates to a log measurement device. Background technique [0002] In domestic and foreign trade, the volume of timber is obtained from the timber size inspection (referred to as the inspection ruler). Therefore, the result of the wood inspection is not only the main reason for the national import and export management department to supervise the imported wood, and the domestic and foreign wood traders to settle the trade results. The basis is also the key for the inspection and quarantine personnel to implement the inspection and supervision of imported timber. [0003] At present, the inspection of wood size is generally carried out by manual inspection, which is labor-intensive and requires high human resources. Since the imported wood is required to be inspected by the standards of the wood exporting countries and regions or the internationally accepted st...
