Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sheet conveying device ltK that conveys paper sheets in a pinched manner using an endless bell, a guide, and a K.

"Prior Art J" For example, in automatic ticket vending machines, currency exchange machines, automatic deposit/withdrawal machines, etc., paper sheets such as banknotes and ticket sheets used therein are conveyed to their storage position, discharge position, counter counting position, etc. A paper sheet conveying device is incorporated for this purpose.

As this type of conventional paper sheet conveying device, in addition to one in which paper sheets are held between a pair or multiple pairs of endless belts and conveyed to a target position, As shown in the figure, a configuration is known in which paper sheets are conveyed while being held between an endless belt and a guide disposed along the endless belt.

Among these, what is shown in FIGS. 9 and 10 is a flat belt type endless belt 3 that is stretched between pulleys 1 and 2 and interlocked, and belts 3 on both sides of the belt 30. A pair of guides 4, 4 are provided at positions spaced apart from each other in the axial direction of the belt 3 so as to extend parallel to the reciprocating portion 3a of the belt 3, and the guides 4.4 are arranged on the upper surface of the reciprocating portion 3aC. It is located slightly lower than the To do this, one side of the paper sheet (hereinafter referred to as paper sheet) 5 is pressed against the belt using the so-called elasticity of the paper industry itself to generate friction, and this frictional force and The sheet 5 is conveyed by driving the belt.

In the examples shown in FIGS. 11 and 12, a so-called round belt with a circular cross section is used as the endless belt 3, and in the example shown in FIG. In other words, a guide 6 for feeding paper sheets 5'ft from both forward moving section 3a and backward moving section 3b.
. . , which differs from the examples shown in FIGS. 9 and 10, but the principle of transporting the paper sheet 5 is basically the same in both examples.

"Problems to be Solved by the Invention" However, in such a conventional paper sheet conveying device, as shown in the figure, guides are arranged at positions spaced apart from each other in the axial direction of the pulley with the belt 3 as the center. Since the sheets 5 are conveyed while being pressed against the outer peripheral surface of the belt 3, the occupied cross-sectional area required for conveyance is also large, as shown by the imaginary lines in FIGS. 10 and 2, for example. However, as a result, there was a drawback that a large conveyance space was required compared to the size of the sheet itself.

However, in the configuration in which sheets are fed from two opposing directions to one direction as shown in FIG. There was also a drawback that it took a while.

Means for Solving Problem J The paper sheet conveying device according to the present invention transports paper sheets using an endless belt stretched between pulleys and driven, and a guide disposed along the endless belt. In the paper sheet conveyance device that conveys paper sheets in a clamping manner, the guide is arranged along a plane perpendicular to the rotation axis of the pulley. Here, the guide is arranged so as to simultaneously guide near both ends of the paper sheet to be conveyed, and also guide the central part of the paper sheet if necessary in relation to the applied endless belt. This also includes configurations that are arranged so that

``Operation'' One side of the sheet to be conveyed is brought into pressure contact with the endless belt.In order to generate the friction necessary for conveyance, the guide is placed along the surface perpendicular to the rotation axis of the pulley. , the guide itself does not have a configuration that expands in the axial direction of the pulley.

In addition, the conveyed filter paper sheets are conveyed in such a manner that one side thereof is in pressure contact with the side edge of the belt, so that the space for conveying the paper sheets is necessarily small.

[Example J Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a first embodiment of the present invention.
An endless belt 13 made of a round belt type with a circular cross section and stretched between I and 12 and driven to run in the direction of the arrow, and a pair of guides 14 and 14 made of linear bodies disposed along this endless belt 13KG. In this image, the guide 14.14 is composed of the reciprocating portion 1 of the belt 13.
It is disposed at a line-symmetrical position with respect to 3a as the center and on a plane perpendicular to the axis of rotation of the boob. That is, in the illustrated example, both guides 14.14 are the reciprocating portion 13ae.
They are arranged so as to extend parallel to each other along the reciprocating portions 13aiC at the upper and lower positions of the center. Furthermore, as clearly shown in FIG. 2, these guides 14.14 are arranged at the side edges of the forward moving section taa in order to press the center of one side of the sheet 15 to be conveyed against the side edges of the forward moving section 13a. It is set so that it is located slightly inside the section.

In this first embodiment, both guides 14.14 are disposed above and below the reciprocating portion 13a of the belt 13 so that the reciprocating portion 13a VCl2 extends. and # along with + in the reciprocating part 13
1 is arranged close to the belt 13 so as to form a vertical line, and as a result, the sheets 15 are also conveyed along the sides of the belt 13, so the conveyance space for the sheets is as shown in Fig. 2. As shown by the imaginary line, it is sufficient to have a cross-sectional conveyance space in which the width d in the axial direction of the pulley is extremely small, and therefore the overall conveyance space can be reduced accordingly. In particular, since the required cross-sectional width d of the transfer space is reduced in this way, it is suitable for reducing the size of a machine in which the transfer device is installed or for reducing the overall thickness in relation to space considerations.

In the figure, 31 indicates a pulley, and 33b indicates a reciprocating portion.

According to this embodiment, as shown in FIG. 6, one side of each sheet 35, 35 is pressed against both side edges of the reciprocating portion 33a and conveyed, so that the sheets 35, 35 are conveyed from two opposing directions. Even if the sheet 35 is configured to be able to be fed, there is no need to use the reciprocating portion 33b of the belt 33, and therefore the time required to transport the sheet 35 to the target position can be shortened.

7 and 8 show a fourth embodiment of the invention, in which four pulleys 4 are provided for each

According to this embodiment, the backward moving parts 43b, 53t+ are also vertically close to each other and travel in the same direction, so if necessary, the forward moving parts 43a, 53
Similar to the part a, a guide (not shown) can be provided to apply pressure so that paper sheets can be conveyed in the opposite direction as well. Of course, this embodiment also has a thin structure as a whole, as in the previous embodiments.

In addition, in the above embodiment, an example in which a round belt with a circular cross section is used as the endless belt is shown, but basically one side of the paper sheet can be pressed against the edge of the belt with an appropriate sg force. It may have any cross-sectional shape, and is not limited to the belt of the embodiment.

"Effects of the Invention" As explained above, the present invention provides a configuration in which paper sheets are held between an endless belt that is stretched between pulleys and can be driven, and a guide that is disposed opposite to this endless belt. In the paper sheet conveying device that conveys paper sheets using In addition, the paper sheets being conveyed are naturally conveyed with one side of the belt in pressure contact with the side edge of the belt. The space can be made sufficiently small. That is, the space factor of the sheet conveying device can be reduced.

In addition, since the paper sheets are conveyed by being pressed against the side edges of the belt, it is possible to feed multiple sheets from different directions or positions and ultimately convey them in one direction. Since both edges of the belt can be used at the same time, it is possible to reduce the time required to convey paper sheets.
