Abstract
A method of emptying trays filled with rod-shaped articles produced in the tobacco industry, which consist of the following stages: the trays designated for emptying are conveyed to the input area of a hopper containing adjacent channels separated by dividers; the rod-shaped articles are transferred from the tray to the channels of the hopper using support plates; the channels of the hopper are filled with the rod-shaped articles; the support plates are retracted from the channels of the hopper; the channels of the hopper are successively emptied into a chute adapted to move between channel outlets of the hopper; finally, the rod-shaped articles are transferred from the channels of the hopper and through the chute to the discharge conveyor moving towards the receiving device. The method is further characterized in that during emptying at least one channel () of the hopper (), the hopper () moves linearly in the direction (S) opposite to the direction (T) in which the rod-shaped articles are transported by the discharge conveyor (); and after the channel () has been completely emptied, the hopper () moves in the direction (S) concurrent with the direction (T) in which the rod-shaped articles are transported by the discharge conveyor (), until it achieves a position in which the outlet of the next channel filled with rod-shaped articles is aligned with the inlet () of the chute (), whereas the hopper () moves at a variable velocity when moving in the direction (S) concurrent with the direction (T) in which the rod-shaped articles are transported by the conveyor.
