Automatic separation method and apparatus for metallic rod

Abstract

The invention relates to a method for automatically separating a metal bar material in a bar material production line and a device thereof. The method comprises the following steps of: collecting shot image information of the end surface of the metal bar material on a conveyor chain by a metal bar material counting technology based on an image identification technology; identifying and counting the metal bar material by the image information of the first end surface; extracting all center coordinate positions of end surfaces of the metal bar material in the first end surface image; and realizing preliminary automatic separation of the end parts of the metal bar material by controlling a separating pulling arm or a separating pulling arm and a retaining arm to be inserted into a proper position in one or a plurality of times. If a subsequent metal bar material pulling system is arranged under every two bar material conveyor chains, the full-automatic separation of the bar material can be realized for bundling. The method has simple operation, and can avoid imprecise quantity of the metal bar material in bundles caused by uncertain factors when artificially separating the metal bar material, improve the efficiency and reduce the labor intensity of workers.

Description

technical field [0001] The invention relates to a metal bar separation technology, in particular to an automatic metal bar separation method and device capable of accurate counting. Background technique [0002] Metal bars, such as stainless steel bars, copper bars, steel bars, etc., have traditionally been bundled and sold by weight. Due to the influence of uncertain factors in the production process of metal bars, there will be a certain range of weight errors among metal bars of the same specification. It is very inconvenient to count only by weight in sales, storage, and use. This method of using weight as the unit of calculation is actually not applicable to the sales, storage, use and statistics of metal bars; because, in actual use, the above-mentioned metal bars are always in the form of "" Root" is used to calculate the quantity. [0003] Since metal rods have various specifications and models, when counting their quantity, the number of metal rods under a certain...
