Description

  The present invention relates to a page turning method and a page turning apparatus for a booklet (hereinafter referred to as a passbook) including a plurality of paper sheets such as a passbook.

  The conventional page turning device is provided with a turning roller at a predetermined turning position on the conveying path, stops the passbook being conveyed at the turning position, rotates the turning roller in a predetermined direction, and rotates from the rotation center of the turning roller to the maximum outer circumference. There are some which perform a turning operation by pressing the turning member protruding to the passbook.

  The passbook includes a medium paper having a thickness of about 0.08 mm and a page number of 18 pages, and a paper sheet having a thickness of about 0.12 mm and a page number of 10 pages. In order to apply a pressing force to the passbook from the rotating turning roller and turn only the uppermost page, the pressing force from the turning roller to the passbook is equal to the number of pages of the passbook (thickness) under the turning roller. It must be in an appropriate range regardless. In order to make the pressing force from the turning roller to the bankbook within an appropriate range, various devices have been conventionally made.

  One of them is a recess formed on the lower side of the turning roller in the conveying path, and a passbook push-up member, a cam rotated by a motor, etc., and a passbook push-up member below the hole provided in the bottom of the recess. And a coil spring push-up mechanism having a coil spring provided between the cams to avoid excessive pressing force from the turning roller to the bankbook (first prior art).

  The other is to rotate the turning roller in a direction opposite to the carrying direction of the book and to make the rotation speed (circumferential speed) of the turning roller slower than the passing speed (circumferential speed of the carrying roller). (Second prior art).

  In the other one, the turning member of the turning roller is formed in a hollow structure with an elastic material, and the turning roller is rotated in one direction (third prior art).

JP 2000-168270 A (first prior art) Japanese Patent Laid-Open No. 2002-225461 (third prior art) Japanese Patent Laid-Open No. 2002-248880 (third prior art)

  The first prior art has the advantage of being able to cope with a relatively wide range of changes in the thickness of the passbook and obtaining the effect of preventing multiple turning, while it has to be provided with a passbook push-up mechanism below the passbook transport surface. Is complicated, and the operation cost is high.

  The second prior art has an advantage that the configuration is simple, but requires a means for making the peripheral speed of the turning roller slower than the peripheral speed of the conveying roller. In particular, the thickness on the side where the passbook is turned is reduced. If it is thick, the pressing force from the turning roller to the bankbook tends to be excessive, and the probability of multiple turning is high.

  And although the 3rd prior art has the advantage that composition is still simpler, it cannot fully respond to the change of the thickness of a wide passbook only by one-way rotation of a turning member. In particular, when the thickness of the side where the passbook is turned is thick, the turning member having a hollow structure is deformed and crushed. Therefore, the turning member becomes hard (elasticity is reduced), and the reaction force of the pressing force from the turning roller to the passbook cannot be absorbed. As a result, the pressing force on the passbook may become excessive, and multiple turning may occur. It cannot be completely prevented.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a page turning method and a page turning apparatus that can solve the problem of occurrence of multiple turning with a simple configuration.

  One aspect of the present invention that achieves the above object is a method of turning a passbook to be turned by stopping a passbook to be conveyed at a predetermined turning position and rotating a turning roller provided at the page turning position. a) When the rear end portion of the passbook to be conveyed reaches the vicinity of the rear end portion of the flat portion that is behind the vertical line passing through the center of rotation of the turning roller and is recessed in the conveyance guide below the turning roller, (B) Rotate the turning roller by a predetermined angle to near the position where the turning member of the turning roller contacts the stopped passbook, and then (c) turn the turning roller and the carrying roller at the same peripheral speed at the same time. When the turning member of the turning roller moves to the lowest point, the conveyance of the passbook is stopped, and (d) the turning roller is rotated to a predetermined angle before the turning member leaves the passbook, and the uppermost middle paper of the passbook is removed. (E) Next, while the rotation of the turning roller is stopped, the passbook is transported by a small distance, and the inflated inner paper is returned a little, and (f) the turning roller is turned so that the turning member exceeds the uppermost point.

  Next, embodiments of the present invention will be described with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes a bankbook inserted in a spread state from an insertion port / discharge port of a bankbook processing apparatus (not shown). A turning roller 2 is provided on the upper side of the transfer surface of the bankbook, and has a turning member 2 a that protrudes from the rotation center of the turning roller 2 to the maximum outer periphery. The turning member 2a is made of an elastic material and has a hollow structure.

  Conveying rollers 3 and 4 are provided before and after the turning roller 2, that is, at a position close to the insertion / discharge port from the turning roller 2 and a position far from the insertion / discharge port, respectively. Each of the conveying rollers 3 and 4 includes driving rollers 3a and 4a provided on the lower side of the conveying surface and driven rollers 3b and 4b provided on the upper side of the conveying surface and pressed against the driving rollers 3a and 4a. It has become. A conveyance guide 5 for guiding the bankbook to be conveyed is provided below the conveyance surface between the conveyance rollers 3 and 4.

  Both front and rear ends of the conveyance guide 5 are present in the vicinity of the drive rollers 3a and 4a, respectively. Further, flat portions 5 a extending over a distance slightly larger than the diameter of the turning roller are formed on the front and rear sides of the vertical line passing through the rotation center of the turning roller 2 at the intermediate portion of the conveyance guide 5. The flat portion 5a is recessed from the guide surfaces 5b and 5c existing on both front and rear sides thereof. Then, inclined surfaces 5d and 5e are formed to connect the end portions of the guide surfaces 5b and 5c on the flat portion 5a side to both end portions of the flat portion 5a. The upper side of the conveyance guide 5 is a turning position.

  Between the driven rollers 3b and 4b of the conveying rollers 3 and 4 and the turning roller 2, a front open guide 6 and a back open guide 7 are provided on the upper side of the conveying surface, respectively. The front open guide 6 is fixed to a support shaft 6a provided in the vicinity of the driven roller 3b, and is rotated 60 degrees counterclockwise in FIG. 1 from a horizontal state around the support shaft 6a by an actuator such as a solenoid (not shown). It can be rotated to the extent. When the turning roller 2 is rotated counterclockwise until the turning member 2a changes from the state existing at the uppermost point to the state existing at the lowermost point as shown in FIGS. The open guide 6 is rotated upward so as not to obstruct the rotation of the turning roller 2.

  Further, the back open guide 7 is fixed to a support shaft 7a provided in the vicinity of the driven roller 4b, and by an actuator such as a solenoid (not shown) from the horizontal state around the support shaft 7a to about 60 degrees clockwise. It can be rotated. Then, as shown in FIGS. 5 to 8, while the turning roller 2 performs the turning operation of the passbook, the back open guide 7 is rotated upward so as not to obstruct the rotation of the turning roller 2.

  As illustrated in FIG. 10, the transport rollers 3 and 4 and the turning roller 2 are rotated in a predetermined direction by receiving driving force from the transport motor M1 and the turning motor M2 which are driving sources. The conveyance motor M1 and the turning motor M2 are rotated / stopped and controlled in rotation direction and rotation angle by a control signal from the control device 8. The control device 8 includes an insertion / discharge detection sensor 9a provided at an insertion / discharge port of the passbook processing device and a passbook position detection sensor 9b provided at a close position on the insertion / discharge port side of the transport roller 3. A detection signal is input from.

  The effect | action by the said structure is demonstrated below, referring the flowchart of FIG. In FIG. 11, the combination of S and a number means a step number.

[initial state]
In the initial state of the bankbook processing apparatus, the turning roller 2 is stopped at an angle at which the turning member 2a exists at the uppermost point as shown in FIGS. That is, FIGS. 1 and 2 show the home position of the turning roller 2.

  When the bankbook 1 is inserted in a spread state from an insertion / discharge port (not shown) on the left side of FIG. 1 (Yes in S1 of FIG. 11), the insertion detection sensor 9a (see FIG. 10) sends an insertion detection signal. Since the output is given to the control device 8, the control device 8 rotates the transport motor M1 in a predetermined direction (S2). Thereby, the inserted bankbook is conveyed by the conveyance roller 3 toward the turning position. A passbook position detection sensor 9b provided in front of the transport roller 3 immediately before the turning position outputs a front end detection signal and inputs it to the control device 8 when the front end of the passbook is detected (Yes in S3). To do.

  Based on the input of the leading edge detection signal, the control device 8 rotates the transport motor M1 (S4), and when the rotation angle of the transport motor M1 becomes a predetermined angle (the number of pulses given has reached a predetermined value). (When Yes in S5), that is, when the bankbook 1 to be transported has reached the turning position, the rotation of the transport motor M1 is stopped (S6).

  More specifically, as shown in FIG. 2, the rear end portion of the bankbook 1 being conveyed is closer to the insertion / discharge port side (left side in FIG. 2) than the vertical line passing through the rotation center of the turning roller 2, When the vicinity of the end of the flat portion 5a on the insertion / discharge port side is reached, the rotation of the transport rollers 3 and 4 is stopped, and the passbook is stopped at that position.

  Subsequently, the control device 8 rotates the turning motor M2 by a predetermined angle while the passbook is stopped at that position (S7), and turns the turning roller 2 counterclockwise in FIG. 3 by a predetermined angle, for example, about 130 degrees. The turning member 2 a of the turning roller 2 is brought into contact with the rear end portion of the book 1, and the rear end portion of the pass book 1 is lightly pushed down to the depressed flat portion 5 a of the conveyance guide 5. As a result, the rear end portion of the bankbook 1 gently rises or curves from the rear end toward the binding direction of the bankbook. This inclined surface or curved surface enlarges the contact area with the turning member 2a when the next turning roller 2 is rotated, and therefore promotes the separation effect of the intermediate paper, that is, the turning effect.

  When the turning member 2a of the turning roller 2 lightly pushes the rear end portion of the bankbook 1 to the flat portion 5a by the rotation of the turning roller 2, the control device 8 simultaneously turns the conveying motor M1 and the turning motor M2 on. As shown in FIG. 4, the conveying rollers 3 and 4 and the turning roller 2 are rotated at the same peripheral speed until the turning member 2 a reaches the lowest point as shown in FIG. 4 (S 8). By rotating the conveying rollers 3 and 4 and the turning roller 2 at the same peripheral speed at the same time, the middle sheet of the passbook is not turned.

  Thereby, even if the turning roller 2 rotates to the lowest point, it does not swell. In other words, if the passbook is left stopped, the pressure applied to the passbook from the turning member 2a increases until the turning member 2a reaches the lowest point, and the force to turn the inner paper works, leading to multiple turning. In order to prevent this, the conveying rollers 3 and 4 and the turning roller 2 are simultaneously rotated at the same peripheral speed.

  Next, as shown in FIG. 4, when the turning roller 2 rotates to the lowest point, the control device 8 stops the rotation of the conveying rollers 3 and 4 as shown in FIG. While the bankbook 1 is stopped, the turning roller 2 is further rotated in the same counterclockwise direction by a predetermined angle, for example, about 40 degrees to inflate the middle paper 1 ′ of the bankbook 1 (S9).

  In this case, the rear end portion of the passbook 1 is lightly pressed down by the flat portion 5a, and is a gently upwardly inclined surface or curved surface from the rear end of the passbook 1 to the upper side of the guide surface 5c of the conveyance guide. In order to apply a turning force to the rear end portion of the bankbook 1, the turning member 2 a swells the middle paper only from the lowest point. That is, since the operation amount for inflating the middle paper is limited, the uppermost middle paper is inflated in the operation range in which the pressure is weakened. Therefore, the possibility of turning a plurality of sheets at the same time is minimized.

  Subsequently, the control device 8 rotates the conveying rollers 3 and 4 by a predetermined angle while stopping the turning roller 2 to convey the passbook by a minute distance, for example, about 5 mm, and slightly expands the inflated intermediate paper 1 ′. Return (S10). In the case where two or more sheets are inflated when the inner sheet is inflated by rotating the pass roller 2 by a predetermined angle in the counterclockwise direction shown in FIG. The paper can be expected to return due to residual stress.

  After the passbook is transported for a minute distance, the turning motor M2 is rotated by a predetermined angle (S11), and the turning roller is turned to an angle exceeding the uppermost point because the turning motor M2 is stopped. Bounce up.

  Thereafter, the control device 8 rotates the conveyance motor M1 in the reverse direction (S12), conveys the bankbook in the reverse direction, and flips the flipped up intermediate paper to the opposite page side of the book.

  Finally, the control device 8 reversely rotates the turning motor M2 by a predetermined angle (for example, about 40 degrees) (S13), and returns the turning roller 2 to the home position. This completes the turning operation for one page.

  The case where the left side page is turned to the right side from the stitches of the passbook has been described above. When the right page is turned to the left side from the stitches of the passbook, the operation is symmetrical in each figure.
