Abstract

The object of the invention is a conveyor system (105), especially for products in batches, and a method of controlling this conveyor system. The conveyor system (105) includes at least two conveyors connected in series and at least one controller. The conveyor system is characterized in that, each successive conveyor is shorter, and at least one controller (200) is configured, when the start conveyor (10) is operating at the start speed V0, to operate the first variable speed conveyor (20) at a high speed of the first conveyor VH1 greater than the start speed V0, thereby transferring the batch of product from the start conveyor (10) to the first variable speed conveyor (20) while increasing the distance between the rows of products in the batch; to operate at least the second and subsequent variable speed conveyor (30, 40) at a high speed of the subsequent conveyor (VH2, VH3, . . . ), the high speed of the subsequent conveyor (VH2, VH3, . . . ) being greater than the high speed of the corresponding preceding conveyor (VH1, VH2 . . . ); after the batch of products has fully departed from the start conveyor (10) onto at least the first variable speed conveyor (20), to decrease the speed of the first conveyor (20) to a low speed of the first conveyor VL1, the low speed VL1 of the first conveyor being lower than the target speed (Vt); and after the batch of products has fully departed from each conveyor (20, 30, . . . ) of the system (105) onto its downstream conveyor (30, 40, . . . ), to decrease the speed of said downstream conveyor (30, 40, . . . ) belonging to system (105) to a low speed of each downstream conveyor VL2, VL3, . . . wherein the low speed of this each downstream conveyor (30, 40, . . . ) is lower than the target speed (Vt) but higher than the low speed (VL1, VL2, . . . ,) of the preceding conveyor (20, 30, . . . ).
