DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a device for stacking sheets, and, in particular, to stacking devices which suitable, for example, for the storage of banknotes in cassettes in service machines.
BACKGROUND OF THE INVENTION
A stacking device as shown in FIG. 1, is known from Research Disclosure No. 24, 820, December 1984. In this device a banknote 5 supplied by a transport system 7 is pushed onto a stack 4 of banknotes in a cassette 3 by means of a pusher plate 6 which moves through the transport plane 8. The stack 4 is supported on a sprung plate 9 and is pressed away from the entry opening 11 of the note cassette 4 by the pusher plate 6 until the banknote 5 has been conveyed beneath retaining lips 12 of the entry opening 11. As soon as the pusher plate 6 returns to its rest position, the banknotes on the stack 4 in the cassette 3 are pressed against the retaining lips 12 by the sprung plate 9. The position of the pusher pate 6 in the rest position is safeguarded merely by the moment of inertia of the drive motor 1.
The endless belts 7 are typically arranged in pairs in a plane parallel to the plane of the drawing in FIG. 1, are in contact over one section in the transport plane 8 and are designed to transport the sheets 5 clamped between the two endless belts 7. The number of pairs of endless belts and their spacing is predetermined by the width of the sheets 5 to be transported.
A pusher plate 6 has a rest position above the transport plane 8 and can be moved perpendicular to the transport plane 8, between two pairs of endless belts 7, towards the cassette 3 which is arranged below the transport plane 8. The pusher plate 6 can be of a shape such that its cross-section forms a substantially flat oval, the generators of the pressing plate 6 preferably lying parallel to the direction of transport of the sheets 5 in the transport plane 8. This shape of the pusher plate 6 prevents the pusher plate 6 from becoming caught on the endless belts 7.
The cassette 3 has a substantially rectangular entry opening 11 on the side facing the transport plane 8. At least two mutually opposing parallel edges of the entry opening 11 are constructed as retaining lips 12 the distance between which is slightly smaller than the corresponding dimension of the smallest permissible sheet 5. Arranged in the cassette 3 is a plate 9 which can be moved parallel no the transport plane 8 and which is pushed away from the floor of the cassette 3 towards the entry opening 11 by means of the compression spring 10. The sheets 5 form a stack 4 on the plate 9 which is pressed against the retaining lips 12 under the action of the compression spring 10.
By means of a crank shaft and the rod linkage 2 the drive 1 is connected to the pusher plate 6 which can be pushed from a rest position on the side of the transport plane 8 remote from the cassette 3 through that transport plane and into the cassette 3. The pusher plate 6 penetrates into the entry opening 11 and pushes the stack 4 and the plate 9 into the cassette 3 against the force of the compression spring 10 until the pusher plate 6 is fully extended.
When the pusher plate 6 is in the rest position, the sheet 5 accepted by a service machine (not shown) and intended for stacking is conveyed by the endless belts 7 of the transport system in the transport plane 8 above the cassette 3. The sheet 5 is stopped above the entry opening 11 and the pusher plate 6 is extended. The sheet 5 is thereby pulled out of the endless belts 7, the sheet 5 nestling against the surface of the pusher plate 6 and being pushed through the entry opening 11 past the retaining lips 12. There, the sheen 5 spreads flat again so that, when the pusher plate 6 is retracted, the sheet catches under the retaining lips 12 and remains in the cassette as the uppermost sheet 5 of the stack 4.
In FR-A-2 453 811 and U.S. Pat. No. 4,011,931, the pusher plate can be moved from the rest position into two predetermined positions. Advancement into the middle position conveys banknotes inserted individually into the machi
