Method of and apparatus for accumulating and manipulating arrays of cigarettes and the like
First Claim
1. Apparatus for supplying groups of commodities to a processing machine, comprising:
- group building means having a plurality of assemblies each including a plurality of group forming units each arranged to gather a succession of groups;
means for transporting groups from said units to the processing machine;
the processing machine being a packing machine having at least two tracks spaced apart from each other by a first distance, said transporting means comprising a conveyor having a plurality of neighboring receptacles spaced apart from each other by identical second distances each of which at least approximates said first distance, each of said receptacles being arranged to accommodate a group of rod-shaped articles;
said transporting means further comprises means for intermittently moving said conveyor by increments each having a length of m second distances, m being the number, of tracks in the packing machine, each group forming means gathering an entire group of rod-shaped articles and transferring the entire group into a receptacle while said conveyor is stopped at a position between incremental movements.

Abstract
Blocks of plain or filter cigarettes are accumulated in at least two group building assemblies each of which comprises at least two block forming units receiving cigarettes by gravity flow by way of upright ducts. The assemblies are adjacent the path of a series of successive receptacles which serve to transport discrete blocks stepwise to a multiple-track packing machine. The units accumulate blocks of cigarettes during intervals which include the duration of at least one stepwise movement of the receptacles and that of at least one period of standstill of the receptacles. Such intervals suffice to ensure satisfactory gathering of cigarettes into blocks of required size and shape at a frequency which is required for full-speed operation of the multiple-track packing machine.
