<p>In connection with making cast paving bricks (4) of concrete with rectangular basic shape, sometimes there is performed a finishing treatment of the bricks by 'rumbling' where the bricks otherwise organised on pallets or a casting board are transferred to a cylindric drum where these are tumbled with the purpose of achieving a surface with particular appearance. It has appeared that rumbled bricks, for price reasons, are preferred to be delivered in bulk, as a subsequent manually performed palletising is a relatively expensive element. Thus there is indicated a sorting unit (2) including a conveyor (6) with a conveyor belt (8) over the surface of which, between a receiving area (14) for the bricks (4) and a delivery area (16), there are mutually spaced guide bars (20) disposed obliquely in relation to the direction of movement (F) of the conveyor, by which the bricks (4) are guided in a row with the same orientation for subsequent palletising by machine.</p> |
