The present invention relates to a sheet feeder for supplying only one sheet of check, bill, etc. in a check processor, and more particularly, to a sheet feeder of a check processor that enables a check, a bill, etc. to be supplied in a single sheet more reliably. will be.

In the sheet feeder of the conventional check processor, an annular rubber gear 32 is fixedly attached to the outer circumferential surface of the cylindrical body 31 that is rotated by the driving of a step motor (not shown), as shown in FIG. An actuating lever 34 elastically supported by the coil spring 33 on one side of the cylindrical body 31 is rotatably installed around the hinge pin 35, and an actuating lever in contact with one side of the rubber gear 32. Friction rubber 36 is fixed to the curved surface 34 of 34, and reference numeral 37 shows a fixing piece for fixing the coil spring 33.

The conventional sheet feeder configured as described above has an operating lever 34 having a friction rubber 36 attached by a coil spring 33 in a state in which the check 38 is inserted in the direction shown by an arrow in FIG. ) Is rotated clockwise around the hinge pin 35, the friction rubber 36 of the operating lever 34 is in close contact with the rubber gear 32 of the cylindrical body 31, the rubber fixed to the cylindrical body 31 The check 38 is moved in the direction of the arrow by the rotational force of the gear 32.

In addition, if the cylindrical body 31 with the rubber gear 32 is rotated in the state where two checks 38 are overlapped and loaded, between the check 38 and the friction rubber 36 and between the check 38 and the rubber gear ( Since the frictional force between the checks 32 and 32 is greater than the frictional force between the checks and the checks, slip occurs between the checks and the checks, and the checks 38 in contact with the rubber gear 32 are transferred in the direction of the arrow, and the friction of the operating lever 34 The check 38 in contact with the rubber 36 is completely transferred after the check 38 in contact with the rubber gear 32 and then in contact with the rubber gear 32 at its rotational force.

However, in the conventional case, when the rubber gear 32 is worn or damaged by fixing the rubber gear 32 to the outer circumferential surface of the cylindrical body 31, the entire cylindrical body 31 to which the rubber gear 32 is attached is attached. There was a problem that must be replaced, and when the elasticity of the coil spring 33 decreases due to repeated use, there are various problems such as the sheet conveyance of the check 38 not being surely made.

Therefore, the present invention was devised to solve such a conventional problem, and it is possible to prevent the loss of other parts by detachable rubber gear on the outer circumferential surface of the cylindrical body, and to increase the friction force on each gear of the rubber gear. Forming an inclined surface with a predetermined inclination angle, the check transfer operation is not only accurate, but also prevents the double transfer of the check several times to improve the reliability of the check processor, which is described in more detail by the accompanying drawings The explanation is as follows.

As shown in FIG. 2 and FIG. 3, the drive shaft 3 of the step motor 2 penetrates and is rotatably installed on one side of the frame 1, and the drive rubber gear is provided on one side of the drive shaft 3; The driving source 5 provided with (4) is fixed so that checks and the like are supplied in a single sheet by friction of the driving rubber gear 4 due to the rotational force of the step motor 2.

The driving timing pulley 6 is fixed to one side of the drive shaft 3 with the fixing member 7 (FIG. 2) as shown in FIGS. 2 and 3, and one side of the frame 1 A coaxial shaft 8 (Fig. 2) is rotatably installed, and on one side of the driven shaft 8, a driven timing pulley 9 is fixed with a fixing member 10 (Fig. 2) to drive the pulley ( 6) and the timing belt 11, and the driven rubber gear 13 is fixed to the left circumferential surface of the driven body 12 (FIG. 3) fixed to one side of the driven shaft 8 by compression.

As shown in FIG. 3, both side flow holes 14c and 14c of the pressing hole 14 in which the friction member 15 is attached and fixed to the curved surface 14a and the leaf spring 16 is interposed between the fixing protrusions 14b on the inner side thereof. ') Is inserted into the fixed shafts 17, 17' of the support plate (not shown) formed adjacent to the drive rubber gear 4 of the drive shaft 3, and the fixed shafts 17, 17 '. The leaf spring 16 is stepped into contact with each other, and a long hole 18 is formed at one side of the support plate, thereby inserting the guide shaft 19a of the compression roller 19 and installing it at one side of the compression roller 19. The one side of the torsion spring 20 is in contact with the guide shaft 19a of the compression roller 19 so that the compression roller 19 is in elastic contact with the driving rubber gear 13 of the driving shaft 8.

As shown in FIG. 3, the check gear plate 21 is provided adjacent to the driving rubber gear 4 and the crimping hole 14 in which a check is inserted, and on one side of the check gear plate 21, the drive rubber gear 4 and Fixing the primary guide plate 22 which is in elastic contact, and installs the secondary guide plate 23 having a curved portion 23a for guiding a check adjacent to the driving rubber gear 4 and the driven rubber gear 13. .

As shown in FIG. 5, fastening protrusions 4a, 13a are formed on the inner circumferential walls of the driving rubber gear 4 and the driven rubber gear 13, and the driving and driven cylinders 5, ( The outer circumferential surface of 12) forms recesses 5a and 12a to which the fastening protrusions 4a and 13a are coupled to exchange the driving and driven rubber gears 4 and 13.

Here, the coupling between the driving and driven cylinders 5 and 12 and the driving and driven rubber gears 4 and 13 is integrally made by forcing the fastening protrusions 4a and 13a to the recesses 5a and 12a. The coupling protrusions 4a and 13a can be separated by removing the fastening protrusions 4a and 13a from the recesses 5a and 12a.

As shown in FIG. 4, the teeth 4b, 13b of the driving rubber gear 4 and the driven rubber gear 13 have teeth 4b, ((b) so as to increase frictional force by widening the contact area. The cross section of 13b) is formed by forming inclined surfaces 4b 'and 13b' of constant angle (alpha) with respect to a tangent line. The constant angle α is preferably about 3 °.

Referring to the effect of the check sheet feeder of the present invention configured as described above are as follows.

As shown in FIG. 3, when a check having a thickness of 0.115 mm is loaded in a state where the distance between the driving rubber gear 4 and the check target plate 21 is set to within 0.2 mm, the check is filled with the aforementioned gap. The first guide plate 22 is inserted into the driving rubber gear 4 and is in contact with one side of the primary guide plate 22.

In this state, when the drive shaft 3 is rotated clockwise by driving the step motor 2, the driving rubber gear 4 in which the inclined surface 4b 'of the tooth 4b is elastically contacted with its own elastic force on one side of the check. The elastic force of the leaf spring (16) by the rotational force of the) and the pressing hole 14 is slightly pushed to transfer the check.

At this time, if two checks are conveyed by overlapping, the rotational force of the driving rubber gear 4 is larger than the friction force of the friction member 15 attached to the crimp 14, and slip occurs between the two checks and the check that overlap. Only the check which contacts the inclined surface 4b 'formed in the angular part 4b of the drive rubber gear 4 is conveyed.

Therefore, it is possible to prevent the transfer of two or more checks.

In addition, as shown in FIG. 3, the check exiting between the driving rubber gear 4 and the friction member 15 of the pressing hole 14 is driven along the curved portion 23a of the secondary guide plate 23. The guide roller 19 is guided between the auxiliary rubber gear 19, and the pressing roller 19 moves clockwise while overcoming the elasticity of the torsion spring 20, and simultaneously transfers the check with the rotational force of the driven rubber gear 13. .

If two checks are conveyed in an overlapped manner, the rotational force of the driven rubber gear 13 is greater than the friction force of the crimping roller 19, and slip occurs between the check and the check. By only moving the check in contact with the inclined surface (13b ') formed in the) is to prevent the double transfer of the check.

Here, the checks in contact with the teeth 4b and 13 are in contact with the inclined surfaces 4b 'and 13', and the checks and the teeth 4b and 13 are compared with the conventional ones in which no inclined surfaces are formed. Since the contact area is large, the frictional force is increased and the sheet feeding is made more smoothly.

Further, recesses 5a and 12a are formed on the outer circumferential surface of the driving cylinder 5 and / or the driven cylinder 12, and the inner circumferential surfaces of the driving rubber gear 4 and / or the driven rubber gear 13 are described above. When the driving rubber gear 4 and / or the driven rubber gear 13 are worn out by forming the fastening protrusions 4a and 13a which are forcibly coupled to the recesses 5a and 12a, the driving cylinder body ( 5) and / or the driven cylindrical body 12 can be obtained economically by replacing only the driving rubber gear 4 and / or the driven rubber gear 13 without replacement.

The sheet feeder of the present invention as described above forms a fastening protrusion on the inner circumferential surface of the driving and driven rubber gear for the transfer of checks, and forms an indentation on the outer circumferential surface of the driving and driven vehicle to replace the driving and driven rubber gear. It is easy to solve the problem of replacing the cylindrical body by damage to the rubber gear as in the conventional case, and also increase the frictional force by forming the inclined surface on each gear of the driving and driven rubber gear to widen the contact area. It is possible to ensure the transfer of checks, and it is possible to completely exclude two transfers of checks by preventing the transfer of two sheets several times.
