DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus having a function of transporting paper sheets, such as a printer, an automatic cash transaction apparatus, an automatic ticket gate, and the like. And a paper sheet transport device.

[0002]

2. Description of the Related Art As a conventional method of transporting paper sheets, for example, as shown in Japanese Patent Application Laid-Open No. 62-219098, an endless transport flat belt is hung on a plurality of pulleys, and 2. Description of the Related Art A method is known in which a flat belt is brought into contact with a sheet to hold the sheet, and at least one of the pulleys is rotated to drive the sheet. As another method of conveying paper sheets, as shown in Japanese Patent Application Laid-Open No. 2-15837, an endless conveying flat belt is hung on a plurality of pulleys, and a roller is brought into contact with the endless flat belt. 2. Description of the Related Art There is known a method in which paper sheets are conveyed by sandwiching paper sheets so as to face each other and rotating at least one of the pulleys. As shown in the above prior art, a belt used for conveying paper sheets is a flat belt.

[0003]

When the endless flat belt is used for transporting paper sheets as described above, there are the following problems. First, other flat belts and rollers that are in contact with and opposed to the flat belt were required to hold the paper sheets. Therefore, in the case of a flat belt, another flat belt, a pulley or a shaft, and in the case of a roller, a roller or a shaft is required. Also,
When the position of the pulley for driving the flat belt is far from the driving source, the driving force must be transmitted by another driving mechanism such as a timing belt or a timing pulley. As described above, a large number of parts were required to convey paper sheets using the flat belt.

Another problem when the endless flat belt is used for transporting paper sheets as described above is a load problem. Since the current flat belt for conveyance mainly uses an elastic belt, when the temperature of the operating environment becomes low, the elasticity of the belt decreases and the load increases sharply. For this reason, the drive source must be set according to the load at low temperatures, and the number of belts may be large, so that a large capacity drive source is required.

An object of the present invention is to reduce pulley driving force.

[0006]

The object of the present invention is to provide a paper sheet transport belt which is driven by being pulled by a pulley, and which transports the paper sheet on a belt surface opposite to a belt surface contacting the pulley. The paper sheet conveying belt is constituted by connecting a plurality of paper sheet holding means made of an elastic material to a belt surface for conveying the paper sheets, and the paper sheet holding means is formed by the elastic deformation thereof. Is achieved by generating a clamping force.

The conveying belt is constituted by connecting a plurality of sheet holding means made of an elastic material to a belt surface for conveying the sheet, and the sheet holding means is held by the elastic deformation of the sheet holding means. And the paper sheets are sandwiched between the back side of the paper sheet transport belt.

Another object of the present invention is to provide a paper sheet transport belt which is driven by being pulled by a pulley and which transports the paper sheet on a belt surface opposite to a belt surface contacting the pulley. The conveying belt is constituted by connecting a plurality of paper sheet holding means to a belt surface for conveying the paper sheets, and the paper sheet holding means is provided on the paper sheet held by the paper sheet holding means. This is also achieved by having a shape that causes deformation and generating a force for holding the paper sheet by elastic deformation of the paper sheet.

[0011] The above object is also achieved by a sheet transport belt similar to any one of claims 1 to 5, wherein a rib is provided on the belt surface in contact with the pulley.

[0012] The above object is also achieved by a paper comprising a plurality of pulleys, at least one belt for transporting paper sheets wound around the plurality of pulleys, and a drive source for rotating and driving the pulleys. In the sheet conveying device, the present invention is also achieved by using the belt according to any one of claims 1 to 5 as a sheet conveying belt.

The above object is also achieved by a paper comprising a plurality of pulleys, at least one belt for transporting paper sheets wound around the plurality of pulleys, and a driving source for rotating the pulleys. In the sheet conveying device, the belt is also used as the sheet conveying belt according to claim 6, and the pulley is provided with a groove that fits into a rib provided on the sheet conveying belt. Is done.

[0014]

The paper sheet holding means made of an elastic material provided on the belt conveying surface side holds the paper sheet by the force generated by the elastic deformation of the holding means when the paper sheet is held. If the paper sheet holding means is shaped so that the paper sheet is deformed when the paper sheet is held by the holding means, the paper sheet is held by the force generated by the deformation of the paper sheet. I do.

The force for holding the paper sheets can be determined according to the elastic material and shape of the holding means, the paper sheets to be conveyed, the resistance acting on the paper sheets in the conveyance path, and the like. .
In addition, a belt for power transmission, such as a timing belt or a V-belt, is provided with the above-described paper sheet holding means so that the power for driving the belt can be transmitted simultaneously with the conveyance of the paper sheets. Even when the position of the pulley for driving the belt is far from the driving source, another timing belt or a power transmission mechanism using a timing pulley becomes unnecessary. Thus, the use of the belt of the present invention eliminates the need for other transport flat belts, pulleys, shafts, etc., which are required in the conventional paper transport apparatus, and simplifies and reduces the size of the paper transport apparatus. Can be realized. In addition, the cost can be reduced by reducing the number of parts. Further, the timing belt has less temperature dependency of the load than the conventionally used elastic flat belt. For this reason, even at a low temperature, the increase in the load is slight. Therefore, if the timing belt is provided with the above-described paper sheet holding portion, the number of belts can be reduced and the load on the paper sheet transport device can be reduced.

Generally, a crowning or a flange is attached to a pulley on which a belt is hung in order to prevent the belt from coming off. However, when a sheet is conveyed using the sheet conveying belt as in the present invention, for example, attaching a flange for preventing the belt from coming off to a timing pulley on which a timing belt is hung requires that the sheet be conveyed. Interference with other types of paper may cause damage to these papers and may hinder conveyance. Therefore, it may not be possible to actually attach the flange, and the belt may come off. A rib is provided on the surface of the belt for conveying the paper sheet where the belt and the pulley are in contact with each other, and a groove is provided in the pulley, and the rib comes into contact with the groove to prevent the belt from coming off.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an embodiment of a paper sheet conveying belt according to the present invention. In this embodiment, the timing belt 2
On the back surface (the surface opposite to the surface in contact with the drive roller), a paper sheet holding unit 1 is provided as paper sheet holding means. The timing belt 2 is no different from the conventional timing belt, and a back rubber 4 for supporting the tension applied to the belt,
A tooth rubber 5 formed integrally with the back rubber 4 and engaging with the timing pulley 3; a tooth cloth 6 forming a surface of the tooth rubber 5;
And a cord 7 built in the back rubber 4 in the longitudinal direction.
The back rubber 4 has a loop-shaped paper sheet holding portion 1 made of an elastic material at a portion opposite to the timing pulley side. A plastic sheet is used for the loop-shaped paper-sheet holding portion 1. The loop-shaped paper-sheet holding portion 1 is bonded to a portion of the back rubber portion 4 of the timing belt 2 opposite to the timing pulley side. I have.

The loop-shaped paper sheet holding portion 1 has a shape as shown in FIG. However, when they are attached to the back rubber portion 4 of the timing belt 2 at a pitch that partially overlaps each other, they are elastically deformed as shown by arrows in FIG. At this time, a pressing force is generated between the adjacent loop-shaped paper sheet holding portions due to elastic deformation. This force is a force that acts on the paper sheet when the paper sheet is conveyed and that resists the conveyance (when the conveyed paper sheet moves while rubbing a nearby component, the paper generated between the paper sheet and the component) Force in the direction of extracting the leaves), it is necessary that the force be sufficient to convey the paper sheets, and when the paper sheets enter between the adjacent loop-shaped paper sheet holding parts. It is necessary that the sheet has a size that allows the sheet to enter without causing buckling or the like of the sheet.

The magnitude of the pressing force described above can be arbitrarily set by changing the material of the elastic material constituting the paper sheet holding portion and the shape of the paper sheet holding portion. As an example of this method, as shown in FIG. 4, paper-sheet holding portions 1-b and 1-b 'having different rigidities are alternately arranged, or as shown in FIG. 1-
There is a method of alternately arranging c and 1-c '.
As shown in FIG. 4, when the paper sheet holding portions having different rigidities are alternately arranged, the paper sheet holding portion having the lower rigidity causes a larger deformation than the paper sheet holding portion having the higher rigidity. For this reason, the force generated by the elastic deformation is increased, and a larger holding force is obtained because the surface for holding the paper sheets becomes wider. Also, as shown in FIG. 5, when the paper sheet holding portions having different shapes are alternately arranged, the rigidity is partially different depending on the shape, so that the magnitude of the deformation occurs in the adjacent paper sheet holding portions,
As the force due to the elastic deformation increases, the surface for holding the paper sheets becomes wider, or the surface becomes a curved surface instead of a flat surface, so that a larger clamping force can be obtained.

The surface between adjacent loop-shaped paper sheet holding portions is smooth so that the paper sheet can enter without any obstacle such as buckling when the paper sheet enters.

The shape of the paper sheet holding portion is a loop shape in this embodiment, but the shape is a loop shape as shown in FIG. 6 or a solid shape as shown in FIG. Of course, a cantilever shape as shown in FIG. 8 may be used. Further, in the embodiment shown in FIGS. 1 to 8, the paper sheets are conveyed while being clamped by adjacent paper sheet clamping portions. However, as shown in FIGS. The sheet may be conveyed while being held between the sheet holding section and the back of the belt. Further, the paper sheets are not held by the force generated by the deformation of the paper sheet holding portion.
As shown in (1), the paper sheet to be conveyed may be deformed, and the force generated at this time may be used to hold and convey the paper sheet.

In each of the above embodiments, the paper sheet conveying belt in which the paper sheet holding portion and the timing belt portion are separate bodies is shown. However, the paper sheet holding portion may be integral with the back rubber portion of the timing belt. In this case,
The looped paper sheet holding portion and the back rubber portion of the timing belt are integrally formed by a mold or the like. If the surface between adjacent loop-shaped paper sheet holding portions is too rough to allow the paper sheet to enter, surface treatment such as coating is performed. Further, as shown in FIG. 12, the back surface of the belt has a paper sheet holding portion mounting portion having a shape to which the paper sheet holding portion can be mounted, and this portion is made of a different material or the same material as the belt. It may be a belt to which a paper sheet holding portion of a material is attached.

In each of the above-described embodiments, the timing belt is provided with a sheet holding portion. However, instead of the timing belt, a sheet holding portion is provided on another belt such as a V belt or a flat belt. You may.

Incidentally, a crowning or a flange is generally attached to a pulley for hanging a belt in order to prevent the belt from coming off. However, when a sheet is conveyed using the sheet conveyance belt as in the present invention, for example, attaching a flange for preventing the belt from coming off to a timing pulley on which a timing belt is hung, damages the sheet. Or may become an obstacle to transport. Therefore, it may not be possible to actually attach the flange, and the belt may come off. to solve this problem,
As shown in FIG. 13, a rib 9 is provided on the surface of the belt 2 where the pulley 3 contacts, and a groove 10 is provided on the pulley 3 so that the rib 9 comes to the groove 10 to prevent the belt from coming off. did.

FIG. 14 shows an embodiment of a paper sheet transport apparatus using the belt of the present invention. The conveyor belt has a timing belt 2 and a looped sheet holding portion 1 provided thereon. This belt has at least two timing pulleys 3
And is driven from a drive source (not shown). The paper sheet 13 is first transported by the transport unit 11 at a transport speed V.
At 1 the sheet is conveyed into the belt. On the other hand, the belt is paper 13
Is driven at a speed V2 that is lower than the transport speed of the sheet, and when viewed from the belt, the sheet 13 enters the sheet holding portion at a relative speed V1-V2. These speeds V1,
V2 is the pitch of the sheet holding section, the length of the sheet holding section,
The optimal relative speed V1- such that there is no obstacle such as buckling of the paper sheet or inability of the paper sheet to enter due to the length of the paper sheet.
It is set to be the value of V2.

According to each of the above-described embodiments, instead of holding the paper sheets between the two belts, the paper sheets are held on the surface of the one timing belt opposite to the surface in contact with the pulley. Since the paper sheets are transported by providing the unit 1, the number of parts is reduced, and the capacity of the driving source can be reduced.
Since the sheet holding portion 1 is provided on the timing belt 2, the decrease in elasticity at low temperatures is reduced, and the increase in the load on the driving source due to the decrease in elasticity is suppressed.

[0027]

As described above, by attaching the paper sheet holding portion to the belt itself, the simplification, downsizing, low cost, and low load of the paper sheet conveying device can be realized.
