Abstract

PURPOSE:To permit a paper sheet to be reversingly guided at high speed, by providing with intermediate portions of confronting endless belts three reversing guide members for bending the belts by an angle of 45 deg. with respect to a paper sheet transferring direction. CONSTITUTION:As shown by an arrow A, a paper sheet 1 fed between belts 9, 10 is gripped by the belts 9, 10 for movement. A reversing guide member 4 having three cylindrical guide members 5, 6, 7 which are inclined by 45 deg. with respect to the axial lines of each pair of rollers 2A, 2B, 3A, 3B causes the paper sheet 1 to change its transfer direction by 90 deg. with respect to its transferred direction A and to be reversed before it is transferred to a direction shown by an arrow by B. In addition, belt guide surfaces 5A, 6A, 7A of the guide members 5, 6, 7 comprising the reversing guide member 4 may be constructed of arcs located on concentric circles having a center O1 so as to cause the paper sheet 1 to change its transfer direction and to be reversed at high speed likewise.

Description

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 capable of reversing and guiding a sheet.

[Conventional technology]

Examples of paper sheet conveying devices that can reversely guide paper sheets include:
As shown in Japanese Unexamined Patent Publication No. 54-57759, there is a belt in which one endless belt is bent using a plurality of rollers, and a direction changing section pinches the paper sheet placed on the belt. It is something that is reversed.

[Problem that the invention seeks to solve]

In the above-mentioned conventional example, since the paper sheet is conveyed while being placed on the belt in a portion other than the reversing section, it is not suitable for reversing and guiding the sheet at high speed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper sheet conveying device capable of reversing and guiding paper sheets at high speed.

[Means for solving problems]

The above-mentioned object of the present invention is achieved by providing three reversing guide members in the intermediate portion of the conveyance path of the endless belts that bend the belts at an angle of 45 degrees with respect to the sheet conveyance direction. Ru.

[Effect]

The paper sheets are always held between the belts when they reach the reversing guide section from the carrying-in section, where they are turned inside out and then conveyed to the unloading section while being held between the belts. As a result, paper sheets can be guided upside down at high speed.

The pair of rollers 3A and 3B mentioned above are connected to a drive source 11.

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

Belt 9.10 as indicated by arrow A by another conveying means
The paper sheet 1 fed between them moves while being held by belts 9 and 10, and at the reversing guide section 4, the paper sheet 1 is rotated in the conveying direction A.
After the direction is changed by 90 degrees and the front and back sides are turned over, the sheet is sent out in the direction shown by arrow B. During the conveyance process of the paper sheet 1, the paper sheet 1 is held between the belts 9 and 10, so that the paper sheet 1 can be conveyed at high speed. Furthermore, according to this embodiment, maintenance of the belts 9 and 10 is easy.

FIG. 2 shows an embodiment of the apparatus of the present invention, and in this figure, the same reference numerals as in FIG. 1 are the same parts. In this embodiment, the belt guide surfaces 5A, 6A of the guide members 5, 6.7 forming the reversing guide section 4 are shown.

7A is composed of circular arcs located on concentric circles having a center point o1.

- With this configuration, the paper sheet 1 can be changed direction and reversed at high speed, similar to the embodiment shown in FIG. Furthermore, by configuring the arrangement of the guide members 5°6.7 as described above, it is possible to suppress movement of the belts 9 and 10 in the width direction, so there is no deviation in the width direction of the sheet 1 at the delivery section. Thus, the paper sheet 1 can be reversed and carried out to a fixed position.

FIG. 3 shows still another embodiment of the apparatus of the present invention, in which the same reference numerals as in FIG. 1 are the same parts. In this embodiment, the reversing guide section 4 is constructed by arranging a plurality of guide members 5B, 6B, and 7B in parallel along a concentric circle having a center point 0□.

With this configuration, the direction of the sheet 1 can be changed at high speed and the front and back sides of the sheet 1 can be reversed, as in the embodiment shown in FIG. .

In the embodiment shown in FIGS. 2 and 3, the belt guide surface 5A of the guide members 5, 6.7.

GA, 7A and a plurality of guide members 5B, 6B.

7B along a concentric circle having a center point 01, as shown in FIGS. 4 and 5, the guide members 5, 6, .
7, each center point 05A of the belt guide surfaces 5A, 6A, 7B,
06A, 07B and a plurality of guide members 5B, 6B, 7
The center points 05B, 06B, and 07B of the arc surface of B may be arranged on the axis parallel to the surfaces of the belts 9 and 10.

FIG. 6 shows another embodiment of the apparatus of the present invention, in which the same reference numerals as in FIG. 1 are the same parts. In this embodiment, a rotatable sphere 12 is provided on the contact surface of the belt of the guide members 5, 6.7.
