[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a transport guide used in an ATM bankbook feed mechanism and the like, and a roller unit assembled to the transport guide.
[0002]
[Prior art]
The ATM normally incorporates a passbook feed mechanism that automatically pulls a passbook inserted by a user from the passbook insertion slot into the machine and returns the completed passbook to the passbook insertion slot.
As this kind of passbook feeding mechanism, for example, there is one using a conveyance guide as shown in FIG. 6 (refer to JP-A-10-162203).
[0003]
The conveyance guide shown in FIG. 6 will be described. A passbook conveyance path 22 is formed by a pair of opposing plate-shaped conveyance guide bodies 20 and 21, and the insertion conveyance path 22 has a passbook insertion in which a passbook is inserted at the base end side. Connected to the mouth. A plurality of pairs of upper and lower roller shafts 23 and 24 are incorporated at predetermined intervals along the conveyance direction of the passbook on the opposite surfaces of the pair of plate-shaped conveyance guide bodies 20 and 21. Thus, the passbook is conveyed by these roller shafts 23 and 24.
[0004]
One of the roller shafts 23 and 24 (for example, the lower roller shaft 24 in the drawing) is for driving, and the other (for example, the upper roller shaft 23 in the drawing) is for tension.
The drive roller shaft 24 is formed by attaching a plurality of drive rollers 25 to the support shaft 24a at predetermined intervals along the axial direction, and the support shaft 24 is forced by a motor (not shown). By rotating, the rollers 25 are rotated in the forward and reverse directions. On the other hand, the tension roller shaft 23 is formed by attaching a plurality of tension rollers 26 to the support shaft 23a at predetermined intervals along the axial direction, like the driving roller shaft 24. . Further, the tension roller shaft 23 is not configured to be forcibly rotated. Instead, both ends of the support shaft 23a are pressed against the driving roller shaft 24 by springs 27 and 27, respectively.
[0005]
Further, a plurality of roller insertion openings 20a,..., 21a... Are formed in the plate-shaped conveyance guide bodies 20 and 21, respectively, and the driving roller 25 and the tension roller 26 are respectively transmitted from these roller insertion openings 20a and 21a. Are partially protruded so as to face each other.
[0006]
In this conveyance guide, the bankbook is sandwiched between the driving roller 25 and the tension roller 26, and in this state, the driving roller 25 is automatically pulled into the machine by rotating in a predetermined direction. Further, the passbook after the entry is automatically returned to the passbook insertion port by the rotation of the driving roller 25 in the opposite direction to the above.
[0007]
[Problems to be solved by the invention]
The above-described conventional conveyance guide has the following problems.
(1) The tension roller shaft 23 has a structure in which a plurality of tension rollers 26 are attached to one roller shaft 23a and a tensile force is applied by springs 27 on both sides of the roller shaft 23a. Although a large tensile force is applied to the tension roller 26, only a small tensile force is applied to the central tension roller 26, and the tensile force applied to both ends and the central tension roller tends to be different. For this reason, there existed a subject that the bankbook which is a conveyance target object may be unable to be conveyed correctly.
[0008]
(2) At first glance, the above-mentioned conventional transport guide seems to be easy to replace the tension roller shaft 23. However, in reality, when the tension roller shaft 23 is replaced, the newly installed tension guide Since it takes time to adjust the pressure applied to the roller 26 and skill is required for recombination and adjustment, there is a problem that the running cost increases.
[0009]
(3) The tension roller shaft 23 has a straight shape at the time of assembly, and of course, it is necessary to avoid deformation such as bending during use, and it is also required to be relatively lightweight. . Considering these conditions, it is advantageous to use a shaft that has been tempered, but if tempered, it will be distorted and straightening work etc. will be required to make it straight. Even when a shaft is used, there is a problem that a significant increase in cost is inevitable.
[0010]
(4) Even if one of the tension rollers 26 attached to the tension roller shaft 23 is damaged, the entire tension roller shaft must be replaced, which is uneconomical. It was.
[0011]

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a conveyance guide according to the present invention and a roller unit assembled to the conveyance guide will be described below with reference to the drawings.
[0019]
FIG. 1 is an enlarged view of a main part of a conveyance guide according to the present invention. In this figure, reference numerals 1 and 2 denote a pair of plate-shaped conveyance guide bodies, and a driving roller 3 and a tension roller 4 are incorporated in the upper and lower plate-shaped conveyance guide bodies 1 and 2, respectively. The rollers 3 and 4 constitute a conveyance guide A for conveying a conveyance object such as a bankbook.
[0020]
As shown in FIG. 3, a plurality of roller insertion openings 2a are formed in the lower plate-shaped conveyance guide body 2, and the tension roller 4 is incorporated in the form of a roller unit 5 in the roller insertion openings 2a. It is. The tension roller 4 in the roller unit 5 is an upper plate-shaped conveyance guide body 1 opposite to the lower plate-shaped conveyance guide body 2 to which the tension roller 4 is assembled by the coil spring 7, that is, It is urged toward the driving roller 3 and can be retracted in a direction opposite to the urging direction.
In FIG. 3, 8 is a paper guide that is formed so as to protrude from the plate-shaped conveyance guide body 2 and conveys a conveyance object such as a passbook in a normal posture without shaking left and right.
[0021]
Similar to the driving roller 25 shown in FIG. 6 described above, a plurality of the driving rollers 3 are attached to the support shaft 3a at predetermined intervals along the axial direction, and are not shown integrally with the support shaft 3a. The motor is forcibly rotated in the forward and reverse directions.
[0022]
The roller unit 5 includes a housing 10 that is mounted in the roller insertion port 2a of the plate-shaped conveyance guide body 2 and a long hole 12 formed in the left and right side portions 11 and 11 of the housing 10. The shaft 13 supported so as to be movable along the long axis direction, the tension roller 4 supported by the shaft 13, and the housing 10 and the shaft 13 are interposed between the shaft 13 and the long hole 12. The coil spring 7 is urged along the long axis direction.
[0023]
The housing 10 is formed in a box shape opened upward so that the tension roller 4 is accommodated therein, and one side portion of the peripheral side portion extends outwardly to form a coil. A spring storage portion 15 is formed. A flange portion 16 projecting outward is formed at the upper ends of the left and right side portions 11, 11 of the housing 10 (see FIGS. 1 and 2). The flange portion 16 is configured so that the housing 10 has a plate-shaped conveyance guide body 2. When the roller is inserted into the roller insertion port 2a in an inserted state, it becomes a locking portion that is locked to the roller insertion port 2a (see FIG. 1). Further, when the housing 10 is mounted in the roller insertion port 2a in an inserted state, the upper surface of the tip end of the coil spring housing 15 abuts the lower surface of the plate-shaped conveyance guide body 2 (see FIG. 1).
[0024]
As shown in FIG. 5, the shaft 13 is formed in a substantially elliptical section with both sides cut off in a flat shape, and an upper surface and a lower surface in the center are formed in arc shapes that bulge outward. ing. Further, locking grooves 13a and 13a are formed on the lower surfaces of both ends of the shaft 13, and an extension portion 7c of the coil spring 7 is locked to the locking grooves 13a and 13a (see FIGS. 1 and 4). ).
[0025]
The tension roller 4 has a cylindrical shape with an appropriate radius, and a through hole through which the shaft 13 passes is formed at the center. A material having a large friction coefficient such as rubber adheres to the surfaces of the tension roller 4 and the driving roller 3 as necessary.
[0026]
The coil screening 7 is bent into a U-shape at the center, and is engaged with an engaging portion 7a that is engaged with an engaging hole 15a formed on the front surface of the coil spring accommodating portion 15 of the housing (FIG. 1, FIG. 4), coil portions 7b and 7b wound on opposite sides on both sides thereof, and extension portions 7c and 7c that are linearly extended from the coil portions 7b and 7b so as to be substantially orthogonal to the axis of the coil. It is made up of. In the center of the coil spring 7, a shaft rod 17 supported and attached to the coil storage portion 15 of the housing 10 is passed.
[0027]
Coil springs 7 having various spring loads are prepared in advance, and a plurality of types of shaft rods 17 are prepared in advance according to the loads of the coil springs 7. Then, the coil spring and the shaft rod 17 are incorporated in the coil unit 5 as a pair, and the load of the coil spring 7 being used can be understood by just looking at the color of the shaft rod 17.
The housing 10, the tension roller 4, the shaft 13, and the shaft rod 17 are each made of resin in consideration of cost and weight reduction.
[0028]
Next, the operation of the conveyance guide having the above configuration will be described.
When, for example, a bankbook as a conveyance object is conveyed to the conveyance guide A and reaches between the driving roller 3 and the tension roller 4, a sensor (not shown) detects that fact and outputs an output signal. On the basis of a signal from a controller (not shown), the driving roller 3 is forcibly rotated in a predetermined direction by a motor (not shown) based on this signal, whereby the bankbook is drawn into the machine. Thereafter, after the passbook is filled in the machine, the drive roller is rotated in the opposite direction to that described above, so that the passbook is returned in the insertion direction as opposed to the above.
[0029]
Here, the tension roller 4 is individually provided in the form of a roller unit 5 to a plurality of roller insertion openings 2a provided in the plate-shaped conveyance guide body 2 and individually moved to the upper drive roller 3 side by a coil spring 7. Built-in in an energized state. Therefore, in the conveyance guide A, urging force in the longitudinal direction and respectively in the transport direction but a plurality of tension rollers 4 is incorporated, the drive roller 3 side of the tension roller 4 of the shaft 13 Can be set to the same value by using the coil spring 7 having the same spring load, for example.
[0030]
For this reason, as described in the prior art, a large tensile force is applied to the tension rollers 26 at both ends, but a small tensile force is applied to the tension roller 26 at the center, and the passbook and the like are accurately conveyed. The situation where it becomes impossible can be avoided, and a bankbook etc. can be conveyed correctly.
[0031]
Since the tension roller 4 is individually urged by the coil spring 7 as described above, for example, it is possible to set a part of the tension roller 4 to a strong spring load, and conversely, a part of the tension roller 4 is weak. The spring load can be set freely. That is, the urging force of the tension roller 4 on the center side of the conveyance guide A can be set stronger than that of the tension rollers 4 on both sides according to the conveyance status. It is also possible to set the urging force of the tension roller 4 on the center side to be weaker than that of the tension rollers 4 on both sides.
[0032]
Further, when the tension roller 4 is damaged, only the damaged roller 4 can be easily replaced, which is advantageous from the viewpoint of running cost.
[0033]
When transporting the bankbook etc., even if the thickness between the bankbooks to be transported changes, or even if the thickness of the place where the tension roller 4 hits in the middle of the transport of one bankbook, Accordingly, since the shaft 13 can freely move along the long axis direction of the long hole 12 formed in the housing 10, the urging force to the passbook of the upper and lower driving rollers 3 and the tension roller 4 is kept almost constant. Therefore, the bankbook can be accurately conveyed from this point.
[0034]
In addition, since the shaft 13 is formed in a circular arc shape in which the upper surface and the lower surface of the shaft swell outward, the tension roller 4 comes into contact with the shaft 13 at points. Therefore, the friction between the shaft 13 and the tension roller 4 is reduced, and the tension roller rotates smoothly. Further, since the tension roller 4 can swing left and right, even when the tension roller 4 receives a moment that the tension roller touches the left and right due to the contact surface with the passbook, the tension roller 4 moves in that direction accordingly. In this respect, the object to be conveyed can be smoothly conveyed.
[0035]
In addition, since various coil springs 7 with different spring loads and shaft rods 17 with different colors are incorporated in the coil unit 5 in advance, only the color of the shaft rods 17 can be seen. Since the load of the incorporated coil spring 7 is known, it is possible to easily cope with a case where it is desired to slightly increase the spring load for maintenance or the like, or vice versa.
[0036]
The extension 7c of the coil spring 7 is engaged with the locking grooves 13a at both ends of the shaft 13, whereby the coil spring 7 causes the tension roller 4 to drive the driving roller 3 via the shaft 13. The shaft 13 is biased to the side, and the shaft 13 is also prevented from coming off from the housing 10. That is, the coil spring 7 not only urges the tension roller 4 in a predetermined direction but also serves to prevent the shaft 13 from coming off.
[0037]
Further, in the housing 10, a flange portion 16 is formed at the upper end of both side portions 11 that support the shaft 13 so as to be engaged with the roller insertion port 2 a of the plate-shaped conveyance guide body 2. Since the locking portion (flange portion) to the insertion port 2a of the plate-shaped conveyance guide body 2 is provided in the vicinity of the portion supporting the shaft 13, the shaft 13 can be supported with a relatively strong force. The tension roller 4 can be smoothly rotated at the point.
[0038]
In the above-described embodiment, the conveyance guide A assembled in the ATM has been described as an example. However, the conveyance guide A and the roller unit 5 according to the present invention are not limited to ATM, and other devices. Of course, it is also possible to be used by assembling.
In the above embodiment, the metal coil spring 7 is used as a member for urging the tension roller 4. However, instead of this, another member, for example, a resin coil spring, may be used. Moreover, you may use the plate-shaped thing made from resin.
[0039]
