US 6,581,927 B2 · Device for separating groups of sheets in an apparatus for forming and banding groups of sheets, such as banknotes

Abstract

A device for separating groups of sheets may be used on an apparatus for forming and banding groups of sheets comprising at least one track to feed the individual sheets to a pick up roller for the individual sheets arriving and to transfer said sheets to a stacking channel, extending along a stacking axis, where the sheets are placed on top of one another in stacks which may be preset and banded, one after another. The device comprises a partial support element for the sheets transferred, which operates between the roller and the channel and is mobile, by means synchronized with the roller, between an operating separation position, in which the element is partially inside the dimensions of the roller, intercepting a portion of a first sheet in a stack to be formed, and a release position, in which the element is outside the dimensions of the roller and close to the mouth of the channel, partially supporting a corresponding presettable stack of sheets fed from the roller.

A device for separating groups of sheets in an apparatus for forming and banding groups of sheets, the apparatus being of the type with at least one track for feeding the individual sheets to a roller which picks up the individual sheets in arrival and transfers the sheets to a stacking channel that extends along a stacking axis and wherein the sheets are placed one on top of another in stacks which can be preset and banded, one after another, the separating device comprising an element for partial support of the sheets transferred, operating between the roller and the channel and mobile, by means synchronized with the roller, between an operating separation position, in which the element is partially inside the dimension of the roller, intercepting part of a first sheet of a stack to be formed, and a release position, in which the element is outside the dimensions of the roller and close to the mouth of the channel, partially supporting a pre-settable stack of sheets fed from the roller.

An apparatus for forming groups of sheets, said apparatus comprising:

a stacking channel wherein sheets are placed one on top of another in stacks;
a track that feeds individual sheets that are to be stacked in the stacking channel;
a roller that picks up the individual sheets from the track and that moves the individual sheets toward said stacking channel;
and,
a separating device for receiving individual sheets from the roller and delivering the individual sheets to the stacking channel, said separating device comprising a sheet support element that moves between:
(i) a separation position in which the support element is located at least partially inside the dimension of the roller and intercepts sheets carried by said roller;
and, (ii) a release position in which the support element is located outside the dimensions of the roller and positioned adjacent a mouth of the stacking channel, said support element at least partially supporting a stack of individual sheets received from the roller when said support element is located in said release position.
