An identifying and accumulating device (1, 10) of articles provided with an identifying code, comprising: a frame; a detecting region, where the articles are positioned in a row in such a way that the relative identifying code is arranged at a side of the row; optical detecting means arranged in proximity of the detecting region for detecting the identifying code of the articles when the articles are arranged in the detecting region; an accumulating region in which the articles coming from the detecting region are accumulated so as to be subsequently packed; the detecting region being interposed between the accumulating region and the optical detecting means and being aligned to the accumulating region and the optical detecting means; a linear guide (6, 60, 61) fixed to the frame; a carriage that is mobile along the linear guide (6, 60, 61); a pusher borne by the carriage, comprising a connecting arm constrained to the carriage and a pushing plate which is borne by the connecting arm, which pushing plate is dimensioned so as to push the articles from the detecting region to the accumulating region; the pushing plate being drawn by the carriage along a straight advancing pathway from a retracted position, in which the pushing plate is interposed between the detecting region and the optical detecting means and wherein the pushing plate is aligned with the detecting region and the optical detecting means, to an advanced position in which the pushing plate is at the accumulating region; the device (1, 10) being characterised in that the pusher further comprises movement means for moving the connecting arm and the pushing plate with respect to the carriage, which movement means enable displacing the pushing plate out of the straight advancement pathway in order that the optical detecting means face the articles arranged in a row in the detecting region so as to detect the relative identifying code. a frame; a detecting region, where the articles are positioned in a row in such a way that the relative identifying code is arranged at a side of the row; optical detecting means arranged in proximity of the detecting region for detecting the identifying code of the articles when the articles are arranged in the detecting region; an accumulating region in which the articles coming from the detecting region are accumulated so as to be subsequently packed; the detecting region being interposed between the accumulating region and the optical detecting means and being aligned to the accumulating region and the optical detecting means; a linear guide (6, 60, 61) fixed to the frame; a carriage that is mobile along the linear guide (6, 60, 61); a pusher borne by the carriage, comprising a connecting arm constrained to the carriage and a pushing plate which is borne by the connecting arm, which pushing plate is dimensioned so as to push the articles from the detecting region to the accumulating region; the pushing plate being drawn by the carriage along a straight advancing pathway from a retracted position, in which the pushing plate is interposed between the detecting region and the optical detecting means and wherein the pushing plate is aligned with the detecting region and the optical detecting means, to an advanced position in which the pushing plate is at the accumulating region; the device (1, 10) being characterised in that the pusher further comprises movement means for moving the connecting arm and the pushing plate with respect to the carriage, which movement means enable displacing the pushing plate out of the straight advancement pathway in order that the optical detecting means face the articles arranged in a row in the detecting region so as to detect the relative identifying code.
