DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sheet conveying device, and more particularly, to a paper sheet conveying device suitable for pinching and transporting paper sheets with a predetermined clamping force.

[Conventional technology]

2. Description of the Related Art Conventional conveyance devices for paper sheets and the like employ a conveyance path using a combination of rollers and guides or a combination of belts and rollers. In addition, from the viewpoint of accurately conveying paper sheets, there is a system that conveys paper sheets using a disk and two cylinders each having a plurality of magnetic pole bodies on the outer circumferential surface, as shown in Japanese Patent Application Laid-open No. 48-83556, for example. .

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, when the conveyance distance of paper sheets is long, it is necessary to arrange multiple rollers, which makes the construction of the conveyance path complicated, and when the paper sheets are transported at high speed, the paper sheets are pulled by the rollers. It is not suitable for high-speed conveyance as it may hang.

An object of the present invention is to provide a paper sheet conveying device that is small, lightweight, and suitable for high-speed conveyance.

[Means for solving problems]

The above object of the present invention is achieved by polarizing and magnetizing the belt itself that clamps paper sheets, passing the magnetized belt around rollers, and arranging the belts facing each other so as to clamp the paper sheets.

[Effect]

The magnetized belt uses its magnetic force to grip paper sheets, etc., so it is possible to secure a predetermined gripping force along the entire conveyance path, allowing sheets to be transported at high speed and reliably. .

〔Example〕

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

Figures 1 to 5 show an embodiment of the device of the present invention, and in these figures, the magnetic belt 1゜2 is magnetized with magnetic poles N and S in the width direction of the belt, and the magnetic poles N and S are magnetized in the longitudinal direction of the belt. Magnetic poles S and N are magnetized in opposite directions at a constant interval (in the conveyance direction of paper sheets, etc.). The pairs of magnetic poles are alternately magnetized around the entire circumference of the belt in the longitudinal direction. The outer peripheries of the magnetic rollers 5.5' and 6.6' are magnetized at the same spacing as the magnetic belts 1 and 2 are magnetized. That is, the position of the magnetic pole of the magnetic belt 1 and the position of the magnetic pole of the magnetic roller almost match. Further, the combination of magnetic poles is arranged so that the magnetic belt 1 and the magnetic rollers 6, 6' are attracted to each other.

Similarly, magnetic rollers 5 and 5' of the magnetic belt 2 are arranged so as to attract each other. Further, the magnetic belt 1 and the magnetic belt 2 are arranged so that an attractive force is generated at the position of the magnetic pole of each part of the belt, thereby forming a conveyance path by the belts and rollers. The magnetic roller 5 is connected to the drive source 3 via the shaft 4. FIG. 2 shows the relationship between the magnetic poles of each part of the conveyance path in FIG. 1 using cross sections and arrow views. FIG. 2 is a front view of one embodiment of the apparatus of the present invention shown in FIG. 1, and FIG. 3 is a sectional view showing the magnetic belts 1 and 2 in a state of attraction in the width direction. FIG. 4 is a sectional view showing the state of the magnetic poles in the width direction of the magnetic belts 1, 2 and the magnetic rollers 5', 6'.

Next, the operation of one embodiment of the above-mentioned apparatus of the present invention will be described.

The rotational force from the drive source 3 is transmitted through the shaft 4.

Rotate the magnetic roller 5. When the magnetic roller 5 rotates, an attractive force is generated between the magnetic poles of the magnetic roller 5 and the magnetic poles of the magnetic belt 2, and the magnetic belt 2 is rotated. magnetic belt 2
and magnetic belt 1 are attracted to each other by magnetic poles, and magnetic belts 2 and 1 rotate synchronously. When the magnetic belts 2 and 1 rotate, the magnetic rollers 5' and 6' also begin to rotate. When a sheet of paper or the like is fed between the magnetic belts 1 and 2 in this state, it is reliably held and conveyed by the attraction force generated by the magnetic poles of the magnetic belts 1 and 2. Further, the magnetic belt 2 and the magnetic roller 5 are attracted to each other by magnetic poles, and due to the nature of the magnetic poles, there is a relationship in which slippage is unlikely to occur. Regarding the other relationships, it can be said that the coupling is due to magnetic force and wrinkles are less likely to occur.

In this embodiment, a case has been described in which there is one pair of belts in the conveyance path, but it is clear that even if a plurality of magnetic rollers are arranged on the shaft 4 and the number of pairs of belts is increased, the above-mentioned effects will be exactly the same.

The clamping force by the magnetic belts 1 and 2 can be achieved to a predetermined value by changing the strength of the magnetic poles, and a uniform clamping force can be obtained over the entire conveyance path.6 Next, other embodiments of the apparatus of the present invention An example will be explained using FIGS. 5 to 7. In this embodiment, as shown in FIG. 6, different magnetic poles are provided on the front and back sides of the magnetic belts 1 and 2 in the width direction. This is a case where the problem occurs on the opposite side of the belt. This is due to the method of magnetizing the magnetic belt when manufacturing it.

According to this embodiment, paper sheets can be transported at high speed in the same way as in the embodiments described above, and the structure of the electric transmission system can be made smaller.

Figures 8 to 10 show still another embodiment of the device of the present invention, and this embodiment can be applied to the entire circumference of the magnetic belt without changing the magnetic pole arrangement in the width direction of the magnetic belt. It is magnetized. Magnetic belt 1゜2 and magnetic rollers 5, 5'
, 6.6' and 6.6' are prevented from slipping due to mutual magnetic force, and load fluctuations or belt start-up,
If the stop is not abrupt, the same effect as described above can be obtained.

Figures 11 to 13 show another embodiment of the device of the present invention.In this embodiment, instead of a magnetic roller, the roller is made of a material that can be attracted by magnetic force, and this is used. 8, and similar effects can be obtained when load fluctuations or belt start-up and stop are not performed suddenly compared to the embodiment shown in FIG.

According to the embodiments of the present invention described above, it is possible to clamp one banknote by placing the magnetized belts facing each other, so that a predetermined clamping force can be secured for the entire conveyance path, and high-speed conveyance of paper sheets is possible. be. Furthermore, by using magnetic rollers, it is possible to prevent deviation due to slipping of the magnetic belt, so synchronized conveyance can be realized, especially in a conveyance path formed by a plurality of pairs of belts. Furthermore, the present invention can be particularly applied to automatic teller machines, etc., and can be installed in a smaller size and lighter weight.
