Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method of compressing and suctioning a large number of bundles of paper sheets that are input at once by means of conveyance means such as rollers and conveyors that face each other across a conveyance path, and then the tip of the sheet is compressed and sucked into paper sheets. The present invention relates to an improvement of a paper sheet feeding device that feeds out paper sheets one by one after being locked to a leaf stop guide plate.

For example, in an automatic cash teller machine, a bundle of banknotes inserted into the slot by a user is sucked through a conveyance path by a conveyance means, is stopped by a sheet stop guide plate, and is then stopped by a feed roller. The sheets are fed out one by one and sent to the identification department where they are checked for authenticity. If the verification result is "OK", the banknote is sent to the store and stored. If the verification result is "NG", the banknote is sent to the pool section and stored. Once all the banknotes inserted have been verified,
"NG" banknotes are returned from the pool section to the return slot,
The "OK" banknote is stored in the banknote storage box by the pusher.

In such devices, it is important for banknote processing that the leading edges of the banknotes are aligned when the banknotes are fed out by the feeding roller. It will be done.

(2) The authenticity of banknotes can be determined efficiently.

(3) Jams on the banknote transport path are reduced.

It has become a necessary condition for operations such as

However, the current situation is that this condition is completely left to the care of an unspecified number of users when making an investment, and there are multiple denominations to be processed, which naturally differ in size and are not uniform at first glance from the outside. Even if it appears to be in place, the small banknotes stuck inside may be tilted. be.

The present invention is intended to realize the above-mentioned demands.
It is an object of the present invention to provide a paper sheet feeding device capable of automatically aligning the leading edges of banknotes input in bulk and then reliably feeding them one by one.

Embodiments of the invention will now be described with reference to the drawings.

FIG. 1 is a front view of an embodiment of the paper sheet feeding device according to the present invention, in which 51 and 52 are guide plates, 53 is a movable guide plate, 54 is a conveyor (conveying means), and 55, 56 57 is a feed roller, 58 is a feed roller, 59 is a stopper, 60 is a sheet stop guide plate, and 61 is a sensor.

The guide plates 51 and 52 are provided facing each other with a conveyance path 62 in between, and have an input port 63 formed at their upper ends.

The sensor 61 is provided along the transport path 62 between the stopper 59 and the paper stop guide plate 60 (before the paper stop guide plate 60), and detects the leading edge of the banknote 40 sucked into the transport path 62. A signal is sent to the drive source for retracting the conveyor 54.

Paper sheets 40, such as banknotes, which are input by the user at once through the input port 63, are caught between the conveyor 54 and the rollers 55, and are stopped by the stopper 59 for a moment. When paper input is confirmed in this state, the stopper 59 moves in the direction of arrow A and retreats from the conveyance path 62, and the paper 40 is transferred to the conveyor 54 and the rollers 55.
It is clamped and conveyed by more pressure. When the leading edge of the paper sheet 40 is detected by the sensor 61, the sensor 61 sends a signal to the drive source for retracting the conveyor 54 and retracting the conveyor 54 from the conveyance path 62. Thereupon, the paper sheet 40 becomes free and until then the conveyor 5
Due to the inertia caused by the energy given by 4, the banknote moves forward to the position indicated by the chain line and collides with the banknote stop guide plate 60,
The impact automatically aligns the tips. Note that the paper sheet 40 that collided with the paper sheet stop guide plate 60
If the belt 66 is made to travel a predetermined amount in the opposite direction to the above-mentioned direction, retreat to the position of the stopper 59, and collide with the bill stopping guide plate 60 again, and then repeat this operation an appropriate number of times, an even greater effect can be obtained. It is possible to play. In addition, the paper leaf stop guide plate 6
