A unit for transferring cigarette sticks form a cigarette maker to a filter tip attachment

Abstract

Cigarette sticks are transferred from a cigarette maker to a filter tip attachment by a unit that includes a conveying roller made to rotate in a first feed direction and furnished with channels aligned on a second direction transverse to the first direction. Each channel accommodates a single stick , directed onto the roller by way of an impeller device , and presents two longitudinal areas designed to make contact progressively with corresponding longitudinal areas of the stick as it advances into the channel, the effect being to create a chamber between the stick and the part of the channel lying between the two longitudinal areas of contact, which is connected to a source of negative pressure.

Description

technical field [0001] The invention relates to a unit for transferring cigarettes from a cigarette maker to a filter attachment device. Background technique [0002] The term "cigarette rolling machine" describes a machine by which at least one continuous cigarette rod advances at a substantially constant speed along its own axis to feed a filter attachment. [0003] Through the exit of the cigarette rolling machine, the continuous cigarette rod encounters a cutting head, by which the cigarette rod is cut into cigarettes of usually "double" length, that is to say, cigarettes of double length will end up with the respective The filters are combined to form a standard filter cigarette. [0004] After the cutting step, the cigarettes continue to advance axially, being pushed forward by subsequent cigarette rods, to a delivery position where each cigarette is engaged by a delivery mechanism running between the exit of the cigarette maker and the filter Between the entrance eq...

Problems solved by technology

If not, the entry velocity to the bottom of the channel will likely damage the cigarette and / or cause the tobacco filler to fall off the end

[0013] Also, because suction channels are commonly formed, considerable pressure loss occurs along the entire length of the channel and around the suction holes.

[0014] In order to overcome such problems, the prior art consists of solutions using high-power suction equipment, together with pneumatic circuits, which are rather complicated and costly due to the provision of ultra-high-strength piping and sealing, As a result, high electrical energy consumption and high noise levels are generated in the pneumatic circuit as the cigarettes enter the corresponding channels
