ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a device for banding groups of sheets.
The invention finds application to advantage in machines by which banknotes, in particular soiled banknotes, are ordered into groups and transferred to a strapper/bander by which at least one band is looped around each single group of notes.
It is well known that banks need to move notable amounts of paper money around on a daily basis, whether central banks by which new banknotes are issued, or trading banks through which the notes are circulated. To this end, banknotes are first sorted into groups and then placed for the purposes of transportation into relative bags or cassettes.
To ensure they can be ordered and transported without the risk of breaking up and to prevent their being tampered with, the groups are secured with bands serving to keep the notes together and minimize opportunities for robbery or pilfering.
Generally speaking, banknotes are fed singly and in succession into a machine of the aforementioned type and, having been examined and sorted according to denomination and/or type, directed separately toward the outlets of respective channels along which the groups are formed.
In this way stacks of single banknotes are formed at each of the outlets and, as the single notes are accumulated in a predetermined number corresponding to one group, taken up and transferred to a station at which it will be suitably strapped or banded.
In view of the considerations mentioned above, the strapping or banding operation needs to be fast and accurate, resulting in an end product characterized by strength and quality.
The prior art embraces machines for strapping and banding groups of banknotes comprising a unit by which a group of notes is gripped, a unit by means of which a continuous strip of material decoiling from a roll is advanced and positioned around the group of notes, and a cutting and sealing unit by which the continuous strip is severed to produce a discrete length and the two ends of the separated length are secured together to form a band.
One of the drawbacks encountered in such machines is attributable to the fact that when the group of sheets is taken up by the gripping device, which operates generally by impinging on the two opposite end faces of the group and applying a compressive force, the section subjected to the gripping action is compacted substantially into a wad, whereas the parts of the sheets not subjected directly to the gripping action tend to fan out in relation to the compacted part.
This effect is especially noticeable in the case of soiled banknotes, due to their imperfect surface flatness and irregular appearance, and to the fact that they are creased.
Because the banding operation is carried out, of necessity, while the group of notes is subject to the action of the gripping device, the positioning of the strip and the arrangement of the banknotes at the fanned-out areas may be incorrect, with the result that the shape of the group of notes when banded appears irregular.
Accordingly, and for the reasons outlined above, machines of the type in question are limited in terms of operating capacity, lacking in precision and not altogether reliable.
The object of the invention is to set forth a device for banding groups of sheets, in particular soiled banknotes, around which bands can be applied both accurately and in such a way as to guarantee strength and quality of the end result.
SUMMARY OF THE INVENTION
The stated object is realized according to the invention in a device for banding groups of sheets appearing substantially parallelepiped in shape, wherein the sheets are caused to accumulate along a longitudinal stacking axis, taken up by respective gripping means engaging two longitudinally opposite ends of at least a first longitudinal portion of the resulting group and fed thus to a station where at least one band of a strip material is applied.
The device disclosed comprises compacting means designed to compress at least a second longitudinal portion of the single group not engaged by the gripping means, in such a way as to position the group of sheets in a configuration of readiness for application of the band.
