Abstract

Abstract A device for forming groups of cigarettes in a cigarette packaging machine, in which an outlet hopper of a cigarette feed apparatus comprises a plurality of adjacent outlet mouths each arranged to deliver successive layers of cigarettes. Pusher means disposed below each outlet mouth insert said layers in superposed relationship into containers uniformly distributed along a conveyor which is mobile stepwise in proximity to the base of the hopper. Each pusher means is operable independently of the others, and can be deactivated on sensing determined irregular situations in the containers or during the starting or stopping stages of the packaging machine.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 167 words
A device for forming groups of cigarettes in a cigarette packing machine, the device comprising: an outlet hopper of a cigarette feed apparatus having a plurality of outlet mouths; a conveyor running along a path and having uniformly distributed on its periphery equispaced containers for said cigarette groups, each container being arranged to receive in succession several superposed layers of cigarettes fed from a respective outlet mouth; control means for sensing the condition of said layers, the control means being disposed along said path of the conveyor; a plurality of pusher means each for feeding a cigarette layer into said containers; operating means associated with the pusher means and adapted to normally operate all the pusher means in unison in determined phase relationship with the conveyor, the pusher means additionally being capable of independent operation relative to each other; and inhibiting means connected to the control means for selectively inhibiting the operation of any one or more pusher means when the condition of a layer is defective.
Claim 2
Independent Claim 167 words
A device for forming groups of cigarettes in a cigarette packing machine, the device comprising: an outlet hopper of a cigarette feed apparatus having a plurality of outlet mouths; a conveyor running along a path and having uniformly distributed on its periphery equispaced containers for said cigarette groups, each container being arranged to receive in succession several superposed layers of cigarettes fed from a respective outlet mouth; control means for sensing the condition of said layers, the control means being disposed along said path of the conveyor; a plurality of pusher means each for feeding a cigarette layer into said containers; operating means associated with the pusher means and adapted to normally operate all the pusher means in unison in determined phase relationship with the conveyor, the pusher means additionally being capable of independent operation relative to each other; and inhibiting means connected to the control means for selectively inhibiting the operation of any one or more pusher means when the condition of a layer is defective.
Claim 3
Dependent Claim 41 words
A device for forming groups of cigarettes as claimed in claim 1, wherein each inhibiting means for a pusher means relative to a determined layer is governed by control means relative to the layer which lies immediately below said determined layer.
Claim 4
Dependent Claim 40 words
A device for forming groups of cigarettes as claimed in claim 1, wherein the inhibiting means relative to the pusher means operating on the first layer of each said container are controlled by switch means independent of said control means.
