Apparatus is disclosed for the distribution of logs into the supply shafts of a plurality of successive grinders from a conveyor line consisting of several belt, chain or other conveyors placed in succession and carrying the logs transversely thereon. The logs are passed from one conveyor to the next and distributed into supply shafts through gaps between the conveyors, which are automatically started for moving the logs on the conveyor line so as to fill the supply shafts. The equipment previously known and used for this purpose has several disadvantages, e.g. the need for sorting of the logs, unnecessary operation of the conveyors, overfilling of the line, etc. The present invention obviates these drawbacks in that the line is provided with sensors for sensing the height of the stack of logs on the conveyor line above each grinder supply shaft, at least two sensors being located above the level of the conveyors so as to control the conveyors adjacent to the shaft, so that they will be started, in motion either simultaneously or separately towards the supply shaft therebetween to ensure that there is always a sufficient supply of logs at the grinder. |
