<p>By an oblique feeding of articles (8) onto vacant areas or trays (4) of a sorting conveyor (2) it is known to use a feeding conveyor (6, 14), on which the articles are successively accelerated up to the required loading speed. This feeding shall be initiated from standstill, when the vacant area (4A, B, C) is located at a certain distance from the place of infeed, and the associated time lapse makes it difficult to arrange for a correct feeding into trays immediately succeeding each other, particularly if the supply of the articles to the feeding conveyor is not fully synchronous. The invention provides for an improvement into different manners, viz. for one thing by a length separation of the feeding conveyor in individually controllable sections (14a-d), whereby one article (8) may be under rapid final loading whilst other articles may be under acceleration at lower speed on the same conveyor, and for another thing by the use of requirement controlled accelerations, which may lead to intermediate velocities higher than the feeding speed. Hereby lately supplied article may catch-up with a vacant tray (4), which could not otherwise be reached with the use of a standard acceleration to the feeding speed.</p> |
