Weighing installation for forming batches of objects whose total weight optimally approaches a predetermined reference weight

摘要

The installation according to the invention comprises cups 1 which can be moved between an active horizontal position and an inactive vertical position; a reserve A in which the cups are grouped together in the inactive position; an activation station B in which the cups are moved one after the other from their inactive position to their active position; a feeding station C in which the objects are introduced into the cups which have reached the active position; a weighing station D; a centralisation station E in which the cups which have been weighed with their contents are grouped together; first drive means 4 for moving the cups from the reserve to the centralisation station; a digital calculator with memory F for determining the weight of the objects contained in each cup and selecting from the centralisation station the cups which contain the objects whose total weight is nearest to the reference weight; discharge means 5 for moving the cups selected by the calculator from their active position to their inactive position; and second drive means 6 for returning the empty cups to the reserve. <IMAGE>
