Abstract
Abstract A discarding device (1) for discarding cigarette packs (PS) not provided with a label or duty stamp (T) comprises an operational endless conveyor (4) driven step by step and carrying a plurality of open containers (5) each adapted to receive one cigarette pack (P). Loading means are provided to load sequentially into said containers (5) the packs (P) not yet provided with labels; and, spaced with respect to one another according to the feed steps of the intermittent conveyor (4), there are provided: a labelling station (S1) where the labels (T) are applied to the packs (P) in the containers (5), a checking station (S2) to detect the presence of the label on a pack, a discard conveyor (2) to discharge the unlabelled packs (PS), and a transfer conveyor (3) to convey the regular (i.e. labelled) packs (P) from a operational conveyor (4) to a further delivery conveyor (22, 23, 24). The discard conveyor (2) and transfer conveyor (3) for the packs (P, PS) consist each of a guided sliding path (6, respectively 7) for the packs, disposed transversely to said intermittent operational conveyor (4), suitably related to the respective dwell stations of the containers (5).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
219 words
A discarding device for discarding cigarette packs which have not been provided with a label or duty stamp, from a cadenced flow of such packs, characterized by the fact that said device comprises an operational endless feeding conveyor (4) driven step-by-step, said conveyor (4) carrying an orderly plurality of open seats or containers (5) each adapted to receive one cigarette pack and which are equally-spaced with respect to each other and in phase relationship with the step-by-step movement of the conveyor (4); a labelling station (S1) where the labels are applied to the packs in the containers; a checking station (S2) to detect the presence of the label on a pack, a discard conveyor (2) for discharging the unlabelled packs from the feeding conveyor, and a transfer conveyor (3) to convey correctly labelled packs from the operational feeding conveyor to a further delivery conveyor (22); said discard conveyor and said transfer conveyor being arranged transversally with respect to the said operational feeding conveyor, and being operationally controlled so as to operate in the dwell periods of the step-by-step movement of the feeding conveyor for causing said discard conveyor to remove from said containers the unlabelled defective packs to be discarded and said transfer conveyor to remove the regular correctly labelled packs to be fed to the further delivery conveyor.
Claim 2
Dependent Claim
219 words
A discarding device for discarding cigarette packs which have not been provided with a label or duty stamp, from a cadenced flow of such packs, characterized by the fact that said device comprises an operational endless feeding conveyor (4) driven step-by-step, said conveyor (4) carrying an orderly plurality of open seats or containers (5) each adapted to receive one cigarette pack and which are equally-spaced with respect to each other and in phase relationship with the step-by-step movement of the conveyor (4); a labelling station (S1) where the labels are applied to the packs in the containers; a checking station (S2) to detect the presence of the label on a pack, a discard conveyor (2) for discharging the unlabelled packs from the feeding conveyor, and a transfer conveyor (3) to convey correctly labelled packs from the operational feeding conveyor to a further delivery conveyor (22); said discard conveyor and said transfer conveyor being arranged transversally with respect to the said operational feeding conveyor, and being operationally controlled so as to operate in the dwell periods of the step-by-step movement of the feeding conveyor for causing said discard conveyor to remove from said containers the unlabelled defective packs to be discarded and said transfer conveyor to remove the regular correctly labelled packs to be fed to the further delivery conveyor.
Claim 3
Dependent Claim
65 words
A discarding device according to claim 1, in which said labelling station (S1), said checking station (S2), said discard conveyor (2) and said transfer conveyor (3) are sequentially arranged along the path of the operational feeding conveyor (4) in the conveying direction of said feeding conveyor, and are spaced with respect to one another in accordance with the feed step of the said feeding conveyor.
Claim 4
Dependent Claim
70 words
A device according to claim 1, in which the feeding conveyor (4) and the delivery conveyor (22) consist of endless conveyors each having an active run which is arranged below the motion path of the cigarette packs, in such a manner as to actually carry the packs, while said discard conveyor (2) and the said transfer conveyor (3) are constructed as dragging conveyors, acting on the cigarette packs from above.
Claim 5
Dependent Claim
66 words
A device according to claim 3, in which the transfer conveyor (3) and the discard conveyor (2) comprise each a slide guide on which the packs can slide, and an overlying endless belt provided with a plurality of cross members arranged so as to engage the packs in the containers of the feeding conveyor and to move the packs over and along the respective slide guide.
Claim 6
Dependent Claim
30 words
A device according to claim 1 further comprising means defining a trap door in said transfer conveyor for the selective removal from said transfer conveyor of packs to be inspected.
