Reservoir For Cigarettes And Like Articles

What is this patent about?

'477 is related to the field of cigarette handling and, more specifically, to reservoir systems used to buffer the flow of cigarettes between a cigarette-making machine and a packing machine. These reservoirs are needed to accommodate variations in the production and consumption rates of cigarettes, ensuring a continuous supply to the packing machine even if the cigarette-making machine temporarily stops.

The underlying idea behind '477 is to improve the reservoir design by incorporating a reversing reservoir conveyor and a horizontally movable carriage with a sensor. This arrangement prevents the formation of voids in the reservoir when the supply of cigarettes is interrupted, thereby avoiding issues like cigarettes rolling and becoming misaligned.

The claims of '477 focus on a reservoir system comprising a delivery conveyor, a reservoir conveyor positioned below the delivery conveyor and running in the opposite direction, a horizontally movable carriage with an end wall to define the stack of cigarettes, and a sensor that controls the carriage's movement based on the cigarette level near the inlet.

In operation, cigarettes are fed into the reservoir via the delivery conveyor. The reservoir conveyor, moving in the opposite direction, accumulates the cigarettes into a stack. The sensor monitors the cigarette level at the inlet and adjusts the carriage's position to maintain a consistent stack depth. If the cigarette supply stops, the carriage moves with the reservoir conveyor, effectively absorbing cigarettes from the delivery conveyor and preventing voids.

This design differs from prior approaches by actively managing the cigarette stack within the reservoir. By moving the reservoir conveyor in the opposite direction to the delivery conveyor and using a sensor-controlled carriage, the system ensures a continuous and stable supply of cigarettes to the outlet, even during fluctuations in the input flow. The sensor-controlled carriage is key to maintaining the stack and preventing disruptions.
