Assembly line measurement device and measurement method for measuring amount of wood chips

Abstract

The invention discloses an assembly line measurement device for measuring the amount of wood chips. The device comprises a blanking conveyor belt, a blanking hopper, a discharging conveyor belt, a feeding conveyor belt, a first supporting frame, a second supporting frame, a weighing sensor, a first laser scanner, a second laser scanner and a third laser scanner. The invention also discloses a measurement method of the device. The method mainly comprises the steps of sequentially scanning the point cloud data of the surface contours of tested wood chips on an assembly line according to the timesequence in different areas; according to the point cloud data of the surface contours of tested wood chips, calculating the corresponding area of a measured surface; multiplying the thickness of each tested wood chip by the corresponding area of the measured surface to obtain the size of the wood chip during each scanning time period; respectively accumulating the size of the wood chip in each area and during each time period, and figuring out the average value of the size, namely the size of the tested wood chip. According to the measurement device and the measurement method, the size of avehicle carriage can be accurately measured. Meanwhile, the advantages of small error, easy operation, simple measuring process, convenient operation and the like are realized.

Description

technical field [0001] The invention relates to a material flow and volume measurement technology, in particular to an assembly line measurement device and a measurement method for measuring the square of wood chips. Background technique [0002] In the wood-based panel processing industry, it is necessary to purchase a large number of shavings, wood chips and other wood chips as raw materials for the production of wood-based panels. In various links such as measurement, the actual weight of wood chips is used as the basis for purchase settlement. The problem with this settlement transaction method is that wood chips are often artificially mixed with various sundries, such as metals, stones, etc., thereby increasing the load capacity. , bringing greater losses to the buyer. The weight and volume of scraps are also important reference indicators for the size and thickness of wood-based panels. Therefore, the weight and volume of wood chips and scraps will affect the subseque...

In actual production work, due to the irregular shape of the particles of wood chips, load cells are usually used to measure the volume of wood chips, but because the moisture content of each particle wood chip is not the same, it affects the weighing quality and volume. The conversion between calculations is inaccurate, because the detection signal of the load cell is easily disturbed during the weighing process, the measurement accuracy is difficult to guarantee, and installation, maintenance, and repair are inconvenient
