Benefits of technology

[0015]The paper-sheet-separating / conveying roller of the present invention has a structure in which a member having the support which is in close contact with one side surface of the rubber member and a member having the support which is in close contact with the other side surface of the rubber member are aligned and fixed in an axial direction. Therefore, the paper-sheet-separating / conveying roller exhibits excellent conveying performance, since the rubber member is sandwiched between the supports at a specific pressure applied to the side surfaces, whereby elastic deflection of the rubber member in a horizontal direction (i.e., lateral deflection of the paper-sheet-separating / conveying surface of the rubber member) is reduced. In addition, the paper-sheet-separating / conveying roller (i.e., the rubber member) can be produced at low cost and can readily achieve a specific dimensional accuracy.

Problems solved by technology

A paper-sheet-separating / conveying roller having such a structure poses a problem in that the disks are likely to deflect in an axial direction.
A paper-sheet-separating / conveying roller having such a structure poses a problem in that high cost is required for forming a groove.

embodiment 1

[0035]FIG. 1 is a schematic representation of a paper-sheet-separating / conveying roller according to Embodiment 1 of the present invention.

[0036]As shown in FIG. 1, the paper-sheet-separating / conveying roller 10 according to Embodiment 1 includes a conveying member 11A, a conveying member 11B, a fixing member 12, a holding member 13A, and a holding member 13B. The roller 10 has, at the center thereof, a shaft 14 inserted therein. As shown in FIG. 1, the shaft 14 is provided with one paper-sheet-separating / conveying roller 10. However, no particular limitation is imposed on the number of paper-sheet-separating / conveying rollers 10 provided on the shaft 14, and the number may be two or more.

[0037]The respective members of the paper-sheet-separating / conveying roller according to Embodiment 1 will now be described with reference to FIGS. 2 and 3. FIG. 2(a) is an exploded perspective view of the paper-sheet-separating / conveying roller according to Embodiment 1 of the present invention; F...

example 1

[0081]A rubber elastic member was formed from ethylene propylene rubber (EPDM), and then cut into conveying members (40 mm in outer diameter×28 mm in inner diameter×3.4 mm in width).

[0082]A fixing member having a main body (Φ35 mm×2.95 mm in width) and protrusions (Φ30 mm×2.95 mm in width) was formed from ABS resin.

[0083]Holding members (Φ35 mm×4.0 mm in thickness) were formed from ABS resin.

[0084]The holding members and the conveying members 11 were moved in an axial direction; the protrusions of the fixing member were press-fitted into the through-holes of the conveying members; and each of the holding members was provided on the end surface of the corresponding conveying member, to thereby produce a paper-sheet-separating / conveying roller of Example 1.

example 2

[0085]The procedure of Example 1 was repeated, except that conveying members (40 mm in outer diameter×29 mm in inner diameter×3.2 mm in width) were employed, to thereby produce a paper-sheet-separating / conveying roller of Example 2.

Abstract

A paper-sheet-separating / conveying roller 10 includes a rubber member (conveying member 11A or 11B) having a specific diameter and a through-hole at the center thereof; a core (protrusion 12b or 12c) inserted in the through-hole; and supports which have a diameter greater than that of the core and smaller than that of the rubber member and which sandwich the rubber member from both sides, wherein a member (fixing member 12) having the support which is in close contact with one side surface of the rubber member and a member (holding member 13) having the support which is in close contact with the other side surface of the rubber member are aligned and fixed in an axial direction.

Description

TECHNICAL FIELD[0001]The present invention relates to a rubber roller for separating or conveying paper sheets employed in, for example, an automatic ticket gate, a cash depositing / dispensing machine, or a bill changer (hereinafter the roller may be referred to as a “paper-sheet-separating / conveying roller”). As used herein, the term “paper sheet” encompasses a variety of paper sheets, PPC sheets, a variety of films, magnetic cards, tickets, banknotes, and similar products.BACKGROUND ART[0002]In an automatic ticket gate, a cash depositing / dispensing machine, a bill changer, an automatic ticketing machine, etc., a paper sheet (e.g., a banknote, a magnetic card, or a ticket) is sandwiched between rollers provided so as to face each other, and is then conveyed by means of sandwiching force between the rollers. For example, as shown in FIG. 9, in the case of a machine for conveying a magnetic card 20 having a printed surface, a paper-sheet-separating / conveying roller 1 having a groove a...
