20130341345 | APPARATUS FOR FEEDING ROD-SHAPED ARTICLES IN A PACKAGING MACHINE - An apparatus for feeding rod-shaped articles in a packaging machine comprises a hopper the lower portion of which is equipped with at least one mouth for dispensing rod-shaped articles, subdivided by a plurality of walls substantially vertical and parallel to each other in a plurality of substantially vertical channels positioned side by side horizontally, each of which is designed to accommodate internally a stack of rod-shaped articles reciprocally superposed; at a position and at a level immediately above that of the upper edge of each of the substantially vertical walls there being positioned a substantially cylindrical roller or rod oscillating in both directions about its axis parallel to the axes of the rod-shaped articles for facilitating the entry in the channels; each roller has the relative axis offset laterally in a horizontal direction relative to the upper edge of the substantially vertical wall below and adjacent to it, and the upper edges of the walls relative to each channel of each mouth of the hopper are positioned at different levels in such a way that the width of the passage defined between each pair of adjacent rollers lying above the walls of the channel is slightly greater than the diameter of a rod-shaped article. | 12-26-2013 |
20140150375 | APPARATUS FOR TRANSFERRING AND CHECKING GROUPS OF SMOKING ARTICLES - An apparatus for transferring and checking groups of articles includes a conveyor moving with intermittent motion to transfer the groups in respective compartments on the conveyor so the groups are moved perpendicularly to planes defined by a layer making up the groups. A checking device operates at a checking station and includes a detecting head which, during a relative movement between the detecting head and each group, checks all the articles making up the group. An actuating mechanism moves the detecting head in both directions between positions situated on opposite sides of the compartment which has stopped in the checking station and imparts to the detecting head, each time a compartment of the conveyor stops at the checking station, a translational movement such that the detecting head moves to the zone opposite to the zone where it is when the conveyor stops. | 06-05-2014 |
