Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for regulating the transport path of paper sheets to a desired path in a magnetically or optically read discriminating device for paper sheets such as banknotes.

Conventionally, in a device that handles paper sheets, such as banknotes, which are weak and have large variations depending on whether they are old or new, paper sheets 1 are transferred to conveyor belts 2, 2, etc., as shown in FIG. The flexible blades 5, 5, whose side edges 3, 3 along the conveying direction of the paper sheet 1 are planted on the rotating shafts 4, 4, impact the paper sheet 1 while being placed and conveyed without being pressed down. It was common practice to restrict the conveyance route and posture by doing so. This is further improved by interposing flexible paper side edge impact plates 6, 6 between the paper side edges 3, 3 and the blades 5, 5, as shown in Fig. 2. Therefore, a device has been proposed in which vibration shock is applied evenly to the left and right side edges 3, 3 of the paper sheet 1.

However, it has become clear that even with the above-mentioned impact method, it is difficult to achieve perfect control of the posture of paper sheets. That is, the blades 5, 5 in FIG.
It is extremely difficult to appropriately select and maintain the relationship between the rigidity of the number of impact plates 6, 6 and the rigidity of the impact plates 6, 6. In order to vibrate, it is necessary to increase the rigidity of the blades 5, 5, etc., and as a result, buckling of the side edges of the paper sheet is likely to occur. On the other hand, if the rigidity of the shock plates 6, 6 is reduced, the blades 5,
5, the rigidity of the shock plates 6, 6 will have to be reduced, and a sufficient regulating force will not be generated after all, or the impact plates 6, 6
The disadvantage was that the paper trailed along the side edges of the paper sheets, which in turn hindered the conveyance of the paper sheets.

The present invention has been made in order to eliminate the drawbacks of the conventional devices as described above, and the movement of the impact plate that regulates the side edges of paper sheets does not depend on the rigidity of the impact plate, but instead relies on magnetic force. It is an object of the present invention to provide a device that simply and reliably regulates the conveyance path and posture of paper sheets by forcibly generating vibrations.

The present invention will be described in detail below based on examples.

FIG. 3 is a diagram showing an embodiment of the paper conveyance path regulating device of the present invention.

In this figure, paper sheets 1 such as banknotes are placed on conveyor belts 2, 2 substantially without restraint and enter regulation devices 7, 7. The regulating devices 7, 7 are provided along the conveyance path with paper sheet side edge impact plates 8, 8, which are arcuate plastic strips having appropriate rigidity with one end fixed and the other end free. 8,
Thin rubber magnets 9, 9 are attached to the free ends of the magnets 8, respectively. Two identical cylindrical magnets 10, 10 are provided in the vicinity of the rubber magnets 9, 9 to face them and rotate, respectively, and non-magnetic magnets are placed on both sides of the rubber magnets 9, 9 at appropriate intervals. Material stopper pair 11, 11
The configuration includes the following.

It is also assumed that this cylindrical magnet has N and S poles distributed on the circumference.

As is clear from the figure, the transport path regulating device configured as described above moves the shock plate to the maximum extent possible according to the rotation of the rotating magnets 10, 10.
Since the vibration is made with an amplitude in the range of 1, it is possible to force the side edge of the paper sheet that has entered the paper into a desired path.

At this time, it goes without saying that it is necessary to take measures such as driving by a common power source so that the phases of the magnetic poles of the rotating magnets 10, 10 on the left and right sides always match.

Further, it is desirable that the magnets 9, 9 provided at the free ends of the impact plates 8, 8 have as small a mass as possible.

This is because when the paper sheets to be conveyed have a wide variation in stiffness depending on whether they are new or old, such as banknotes, it is desirable that the inertia of the impact plate be small in order to prevent buckling of the paper sheets. be.

Further, when a paper sheet whose side edges are bent from the beginning enters the regulating device of the present invention, the bending may increase due to impact on the side edges. In order to prevent this, paper sheet bending prevention plates 12, 12 are provided to sandwich the impact plates 8, 8 above and below, as shown in FIG. A large number of anti-bending pieces 13, 13, . . . may be formed to protrude from the edge so as to sandwich the side edge of the paper sheet.

In the embodiment, only the paper sheet conveyance path regulating device 7 is provided along both side edges of the paper sheet, but the present invention does not necessarily have to be limited to this. It is also possible to provide a guide rail, and the rest to be a mere guide rail.

Since the present invention is constructed as described above, impact vibrations against the side edges of paper sheets are forcibly and reliably generated, and the impact force is largely dependent on the mass of the impact plate 8 and the attractive force of the magnet. Since there is almost no need to consider the rigidity of the impact plate 8 and other related members and their balance, the design becomes easy.

In addition, even if the rigidity of the various members mentioned above changes slightly, it will not have a serious effect on the function, making maintenance extremely easy and making it possible to regulate the paper conveyance path stably, which is useful in devices such as mark reading devices for paper sheets. It has a profound effect.
