In connection with making cast paving bricks of concrete with rectangular basic shape, sometimes there is performed a finishing treatment of the bricks by “rumbling” where the bricks otherwise organized 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 pelletizing is a relatively expensive element. Thus there is indicated a sorting unit including a conveyor with a conveyor belt over the surface of which, between a receiving area for the bricks and a delivery area, there are mutually spaced guide bars disposed obliquely in relation to the direction of movement (F) of the conveyor, by which the bricks are guided in a row with the same orientation for subsequent pelletizing by machine.
Arranging unit for arranging items, wherein the arranging unit includes a plane conveyor with a largely horizontally running conveyor belt with a front end and a rear end, wherein the rear end includes a receiving area for supplying items which are laid on the conveyor belt, and wherein from the receiving area and to a delivery area at the front end of the horizontally running conveyor belt at a level above the horizontally running conveyor belt there is a horizontal support beam obliguely oriented in relation to the conveying direction (F) of the horizontally running conveyor belt, wherein the horizontal support beam includes a plurality of mutually spaced guide bars extending downwardly from said support beam and being displaced in parallel and with an inclination relative to the beam, with a front side oriented obliquely against the direction of conveying (F) of the horizontally running conveyor belt, and wherein the undersides of the bars extend substantially in parallel with and immediately over the surface of the horizontally running conveyor belt, further comprising an adjustment structure for adjusting the inclination of the support beam relative to the conveying direction (F) of the horizontally running conveyor belt.
