Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a page turning apparatus.
[0002]
[Prior art]
FIG. 5 shows a conventional example of a page turning device used in an ATM (Automatic Deposit Payment Machine) or a counter used in a financial institution. In this conventional example, the page turning apparatus includes a pair of turning rollers 2 and 2 that are driving rollers, and a guide body 3 that is pivotally supported at the tip of a rotatable support link 6. The turning operation of the passbook (booklet medium 1) is performed by rotating the right turning roller 2 in a state where the passbook 1 is restrained by the left turning roller 2 in FIG. The guide body 3 presses the turning target page 1a from above in order to increase the contact pressure of the turning target page 1a to the turning roller 2 and further to jump up the turning target page 1a beyond the top of the turning roller 2.
[0003]
[Problems to be solved by the invention]
However, the conventional example described above has the following drawbacks. That is, since the page turning apparatus needs to be configured so that the page turning operation can be performed with respect to the conveyance in both the forward and reverse directions, the guide body 3 has the page turning target page 1a inflated as shown in FIG. When the state is reached, it is arranged to maintain a horizontal posture. In a state in which the top of the turning target page 1a is pressed down in the downward direction, the force on the turning target page 1a increases, and as the friction coefficient decreases due to wear or deterioration of the turning roller 2, the passbook 1 is stored. Since the downward pressing force is larger than the frictional force generated by the turning roller 2, it is difficult to ensure a stable page turning operation.
[0004]
The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide a page turning apparatus that does not deteriorate reliability even in long-term use.
[0005]
[Means for Solving the Problems]
When the turning target page 1a is turned by the turning roller 2, the booklet-like medium 1 is conveyed by the turning roller 2 to a predetermined position with the binding side of the turning target page 1a as the head. The rotation direction of the turning roller 2 during the conveying operation is uniquely determined by the conveying direction, and the end of the holding lever 5 connected to the rotating shaft 4 of the turning roller 2 located on the binding portion 1b side of the booklet-like medium 1 is at the tip. It rotates and moves to the other turning roller 2 side, that is, the free end edge 1c side of the turning target page 1a, and presses the binding side edge of the guide body 3 from above.
[0006]
The guide body 3 whose one side edge is pressed is swung around the swing center so as to be higher on the free end edge 1c side of the turning target page 1a and lower on the opposite side, thereby pressing the turning target page 1a. Since the curving point of the turning target page 1a moves to the other turning roller 2 side by the pressing by the guide body 3, the turning target page 1a is strongly against the other turning roller 2, that is, the turning roller 2 that performs the turning operation. As a result, the reliability of the turning operation is improved.
[0007]
Further, since the pressing lever 5 is connected to the rotating shaft 4 of the turning roller 2 so as to be able to idle when an idling torque of a predetermined pressure or higher is applied, the guide lever 3 interferes with the guide body 3 while the bankbook 1 is being conveyed. After tilting the body 3, the body 3 idles with respect to the rotating shaft 4 and does not give an excessive swinging force to the guide body 3.
[0008]
Further, when the turning operation is completed and the bankbook 1 is conveyed in the reverse direction, the pressing lever 5 returns to the original position, and the next turning operation can be performed under the same conditions.
[0009]
In addition, since the relationship described above is established even when the conveyance direction of the bankbook 1 is reversed, it can be applied to a conveyance path having either a normal or reverse conveyance direction, and versatility is improved.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the page turning apparatus includes two sets of turning roller pairs 7 and 7. Each turning roller pair 7 is composed of a turning roller 2 disposed above the conveyance surface 8 and a driven roller 7a. The turning roller 2 is driven to rotate as a driving roller, whereby the bankbook 1 is turned to a predetermined turning direction. It can be transported to a position.
[0011]
Two pressures 9 having a rotation center at the center position between the pair of turning rollers 7 and 7 are arranged in the back direction in the middle portion of the roller pair and below the conveying surface 8. Each of these pressures 9 can be rotationally driven from a position parallel to the conveying surface 8 to a protruding position where the pressure 9 protrudes to the conveying surface 8 shown in FIG.
[0012]
Reference numeral 6 denotes a support link whose one end is pivotally supported above one turning roller 2, and a guide body 3 is swingably connected to the other end. As will be described later, the swing center of the guide body 3 is positioned at the center between the pair of turning rollers 7 when the turning operation is not performed so that it functions in the same direction in both forward and reverse transport directions. Set to
[0013]
Further, a pressing lever 5 is connected to the rotating shaft 4 of each turning roller 2. As shown in FIG. 1B, the holding lever 5 has a housing wall surface or the like in which a shaft insertion hole 5a formed at one end is loosely fitted to the rotating shaft 4 and one side wall surface of the rotating base end portion is close. The non-rotating member 10 is in contact with the rotating shaft 4. Further, a compression spring 11 is mounted around the rotation shaft 4 of the turning roller 2 between the rotation base end portion of the pressing lever 5 and the turning roller 2, and the rotation base end portion is pressed against the non-rotating member 10.
[0014]
As shown in FIG. 1A, the pressing lever 5 is mounted on the rotating shaft 4 of each turning roller 2 so that the tip is located above the conveying surface 8, that is, on the guide body 3 side and faces the same direction. Is done.
[0015]
The operation of the page turning apparatus configured as described above will be described. For convenience of explanation, the bankbook 1 is transported from the right side to the left side in each drawing and the page turning operation is performed, and the turning operation is performed by the right turning roller 2, and the right turning roller 2 is turned. The operating roller 2A and the left turning roller 2 are called holding rollers 2B.
[0016]
As shown in FIG. 4, the turning operation is performed in the order of the inflating step (S10), the flip-up step (S20), and the transporting step (S30). In the inflating step (S10), the bankbook 1 is first turned into a pair of turning rollers. 7, after the binding portion 1 b is conveyed to the turning position beyond the holding roller 2 </ b> B, when the sensor (not shown) detects that the turning position has been reached, the operation of the pair of turning rollers 7 is stopped and the passbook 1 is turned. To stop. As shown in FIG. 1A, the rotational movement of the turning roller 2 is transmitted to the holding lever 5 via the compression spring 11, so that the holding lever 5 connected to the rotating shaft 4 of each turning roller 2 is By rotating clockwise, the tip of the holding lever 5 on the holding roller 2B side moves above the page 1a to be turned. As the pressing lever 5 rotates, the rotation base end eventually comes into contact with the side edge of the guide body 3 on the holding roller 2B side, and the tip end comes into contact with a stopper 6a provided on the support link 6 respectively.
[0017]
In this state, since the rotation resistance is generated in the holding lever 5, even if the holding roller 2B further rotates, the boundary surface between the compression spring 11 and the holding roller 2B or the holding lever 2 and the compression spring 11 In order to slip at the boundary surface, the holding lever 5 idles with respect to the rotating shaft 4 and maintains the position.
[0018]
After the passbook 1 is set at the turning position as described above, the driven roller 7a on the turning operation roller 2A side is lowered to release the restriction on the turning operation roller 2A side, and the binding portion 1b side of the passbook 1 is held. Restrained by the driven roller 7a corresponding to the roller 2B. Thereafter, as shown in FIG. 2, when the turning roller 2 </ b> A is rotated clockwise while the pressure 9 on the turning roller 2 </ b> A side is raised on the conveying surface 8, the bankbook 1 is slightly curved upward and turned. When the pressing force against the operation roller 2A is increased and the turning operation roller 2A is further rotated clockwise, the center portion of the turning target page 1a is curved upward while the free end is pushed out to the center. In FIG. 2 and subsequent figures, in order to simplify the drawing, the illustration of the pressing roller 5 on the side of the turning operation roller 2A that is not used for the turning operation in the direction is omitted.
[0019]
Following the bending of the turning target page 1a, the guide body 3 is pushed upward, and when the non-illustrated transmissive sensor is turned OFF and the completion of the bending of the turning target page 1a is confirmed, the rotation of the turning operation roller 2A is stopped. Then, the inflating process is completed. In the inflating process, the side edge 5b of the guide body 3 on the holding roller 2B side is pressed by the pressing lever 5 to which a resistance due to frictional force is applied in the rotation direction, so that the amount of ascent on the turning roller 2A side increases. The guide body 3 is inclined. As a result, the turning target page 1a is pressed against the turning operation roller 2A side to generate a necessary frictional force, thereby improving the reliability of the turning operation.
[0020]
The flip-up step (S20) is performed by rotating the turning operation roller 2A clockwise again after the pressure 9 is lowered. As the turning operation roller 2A rotates, the turning target page 1a is curved while further reducing the curvature of curvature, and then the free end rides on the turning operation roller 2A as shown in FIG.
[0021]
The end of the flip-up process (S20) is detected when the guide body 3 is lowered slightly with the flipping of the page 1a to be turned and the transmission type sensor is turned on, and the flip-up process (S20) is completed. Upon detection, the driven roller 7a on the turning roller 2A side is returned to the original position, the restraint on the holding roller 2B side is released, and the right side with the free edge 1c on the turning roller 2A side at the head is further released. A carrying step (S30) is carried out. As shown in FIG. 3 (b), the page to be turned 1a is flipped up on the turning operation roller 2A in the conveying step (S30) so that the page 1a to be turned is pressed down by the turning operation roller 2A and overlapped on the adjacent page. The operation is complete.
[0022]
In the above description, a case has been described in which the bankbook 1 is conveyed from right to left and set at the turning position, and again conveyed to the right side to perform page turning. However, the operation in the reverse direction is performed in exactly the same manner.
[0023]
【The invention's effect】
As is apparent from the above description, according to the present invention, the reliability is not lowered even during long-term use, and the structure is simplified.
