The invention concerns an equipment for the automatic tray positioning of single cylindrical or spherical pieces, in particular sausages or other alimentary products. The equipment comprises a first conveyor for the feeding of a sequence of single pieces along a first direction and a second intermittent advancement conveyor or the feeding of single trays along a second direction substantially perpendicular to said first direction. There are also provided a first sensor for the detection of the passage of the single pieces, a second sensor for the detection of the passage of the single trays, and an electronic control device that receives signals from said sensors and controls an advancement step of said second conveyor, with pre-established delay and in measure at least equal to the width of said pieces, at each pre-established number of passages of the pieces in correspondence of said first sensor and a further advancement step of said second conveyor, up to a position determined by said second sensor and suitable to allow to the next empty tray to receive a first piece from said first conveyor, at each predetermined multiple of said pre-established number of passages of pieces in correspondence of said first sensor. An oscillating blade located at the output of said first conveyor provides to the alignment of single pieces at the moment of their entrance into the tray.
