Description

  The present invention relates to a page turning device for a printing device such as a passbook used in a financial institution or the like.

The page turning device is installed in a window of a financial institution or the like, and is installed in a booklet processing device or the like in which a booklet is inserted and processing such as reading of characters and data and printing is performed.
In such a booklet processing apparatus, when transaction data is printed on the passbook by the printer unit, if printing is performed up to the last line of the page in the middle of printing, the passbook is sent to the page turning apparatus and page turning is performed. Printing continues again in the printer unit.

18A to 18E are diagrams illustrating an operation process of a movable panel mounted on a conventional page turning apparatus.
The movable panel 124 is controlled to be opened and closed by a lock lever 128. When the page is not turned, the movable panel 124 is locked so as not to cause jamming due to deformation of the paper (page). It becomes. Further, when turning the page, the lock is released and the movable panel 124 is opened to secure a space for turning the page. Furthermore, when the movable panel 124 falls by its own weight after the turning is finished, it has a function as a detection lever that detects whether the page turning is successful or not at the angle of the movable panel 124.

  FIG. 18A shows a state where the pair of left and right lock levers 128, 128 'are at the home position. Here, for the sake of convenience, only the movement of one (right side) lock lever 128 will be described.

  The lock lever 128 can swing in the directions of arrows p and p ′ around the fulcrum shaft 129 on the proximal end side, and an engagement pin 128a is implanted on the distal end side. In addition, the movable panel 124 is bent into a U-shape with one end being a free end to form an engaging portion, and the other end is pivotally mounted about a fulcrum shaft 132. When the lock lever 128 is at the home position, the movable panel 124 is engaged with the engagement pin 128a. At this time, the movable panel 124 constitutes a part of the transport path.

  FIG. 18B shows the state of the movable panel 124 when the lock lever 128 is in the unlock position. At this time, the lock lever 128 is slightly rotated about the fulcrum shaft 129 in the arrow p direction. Further, the movable panel 124 has a U-shaped portion (engagement portion) at the tip thereof disengaged from the engagement pin 128a and is rotated in the direction of the arrow q about the fulcrum shaft 132.

  FIG. 18C shows a state where the lock lever 128 swings to the maximum. At this time, the movable panel 124 is flipped up by the engagement pin 128a and is in a state of being opened to the maximum with the fulcrum shaft 132 as the center. From this position, the lock lever 128 rotates in the direction of arrow r toward the home position.

  FIG. 18D shows a state where the page turning is finished and the lock lever 128 is returned to the home position. At this time, the movable panel 124 falls in the direction of arrow s by its own weight from the position shown in the figure.

FIG. 18E is a diagram illustrating an example when the movable panel 124 fails to engage (lock).
As shown in the figure, depending on the return timing of the lock lever 128 and the fall timing of the movable panel 124, the U-shaped portion at the tip of the movable panel 124 may not be able to engage with the engagement pin 128a and may fail.

  That is, since the movable panel 124 is returned to the home position by its own weight and the lock lever 128 is returned to the home position by power, the movable panel 124 may not catch up with the retracting operation of the lock lever 128, resulting in a lock failure.

By the way, conventionally, for example, a technique described in Patent Document 1 is known as a locking means for such a panel or cover.
This patent document 1 relates to a cover locking device. When the cover is closed, the slope of the L-shaped claw on the cover side is spread while sliding against the slope of the fixed claw on the body frame side, and is caught by the fixed claw. The general structure is disclosed (refer to the cited example FIG. 3).

  For example, Patent Document 2 relates to a locking mechanism such as a printer cover built in an ATM (Automatic Teller Machine) or the like. In Patent Document 2, the locking claw is biased in a predetermined direction by a spring, and when the cover is closed, the inclined surface provided on the claw portion at the tip of the lever slides on the locking stud, and the locking stud Is disclosed (see reference example FIG. 6).

Japanese Patent No. 3313166 Japanese Utility Model Publication No. 5-31961

  However, according to the above-described conventional page turning device (FIGS. 18A to 18E), even if the movable panel 124 can be finally locked by performing the re-locking operation, the movable panel is locked until it is locked. If vibration or the like is generated in 124, it is not possible to shift to the next operation. For this reason, it is necessary to provide a waiting time, which results in a large time loss.

  In both Patent Document 1 and Patent Document 2, since the lock is automatically applied when the operator forcibly closes the cover, the force and closing speed for closing the cover depend on the manual operation of the operator. Yes. For this reason, in patent document 1 and patent document 2, it is difficult to consider that a lock failure occurs, and it is not necessary to consider the occurrence of a lock failure.

  The present invention has been made to solve such a problem. The movable panel is retracted at an early stage so as not to interfere with the page turning operation, and the movable panel is securely locked to the paper guide. An object of the present invention is to provide a page turning apparatus capable of shortening the time of turning operation.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an external view of a page turning apparatus 10 according to the present embodiment, FIG. 2 is a diagram showing the configuration of the main part thereof, and FIG. 3 is a diagram showing the lock lever 28 and the movable panel 24 when the lock lever 28 is at the home position. FIG.

  In FIG. 1, this page turning apparatus 10 has a main body frame 11 that covers the bottom and side surfaces, etc., and presses a turning roller 16 against a turning page 14a of a booklet 14 inserted in the direction of arrow A in the conveyance path 12. In this device, the page turning is performed by rotating the page turning roller 16 so that the page turning page 14a jumps up above the page turning roller 16. Note that a booklet presser 21 is provided on the drive shaft 15 of the turning roller 16 so as not to rotate coaxially therewith.

  In FIG. 2, the page turning device 10 is pivotally mounted on the rear side in the conveying direction with the turning roller 16 interposed therebetween, and the closed position that constitutes the conveying path 12 and the opening that is flipped upward from the conveying path 12. A movable panel 24 that can be moved to a position (refer to a one-dot chain line), a movable lock claw 30 that is pivotally attached to the movable panel 24 at one end, and the movable panel 24 that is linked from the closed position toward the open position. An engagement pin 28a (see FIG. 3) as an engaging portion is engaged with the movable lock claw 30 at the closed position of the movable panel 24, and is released from the movable lock claw 30 at the opened position; First and second sensors 22 and 23 are provided as detection means for detecting the tilt angle of the movable panel 24 during the turning operation.

  In the present embodiment, the case where the movable panel 24 is provided behind the winding roller 16 in the conveying direction will be described. However, in practice, the movable panel 24 is also provided in front of the conveying direction with the winding roller 16 interposed therebetween. And a movable panel 24 ′ and the like are provided at symmetrical positions.

  Since the movable panel 24 and the movable panel 24 ′ are substantially the same in operation, the members on the front side in the transport direction corresponding to the members on the rear side in the transport direction will be denoted by the reference numerals. (Dash) is attached and the description is omitted.

The first and second sensors 22 and 23 are light emitting elements of photoelectric sensors, and a light receiving element (not shown) is provided in the optical axis direction.
The turning roller 16 is made of an elastic friction member such as rubber and is fixed to the drive shaft 15. The driven roller 17 is urged toward the squeezing roller 16 with a predetermined urging pressure so as to face the squeezing roller 16.

  Further, a conveying roller 18 and a driven roller 19 facing each other are provided at the rear of the turning roller 16 in the conveying direction. The booklet 14 is nipped and conveyed between the turning roller 16 and the driven roller 17 and the conveying roller 18 and the driven roller 19. In addition, a pressure 25 is provided below the intermediate conveyance path 12 in the conveyance direction between the turning roller 16 and the conveyance roller 18.

  As shown in FIG. 3, the lock lever 28 reciprocally swings between a home position (solid line) and a turn position (one-dot chain line) by driving a cam position motor (not shown). Accordingly, the movement of the movable panel 24 from the closed position (solid line) to the open position (one-dot chain line) is flipped up by the lock lever 28, and from the open position (one-dot chain line (24)) to the closed position. Fall to (solid line) under its own weight.

  The movable panel 24 forms a part of the upper plate 12a (see FIG. 2) of the conveyance path 12, and the front side in the conveyance direction is a free end, and the rear side in the conveyance direction is centered on the upper plate 12a and the rotation shaft 32. It is pivotally mounted so that it can rotate. As described above, the movable panel 24 is movable to a closed position that constitutes the transport path 12 and an open position that is flipped upward from the transport path 12.

  In addition, the movable panel 24 includes a side portion (one side end of the drive shaft 15) away from the conveyance path 12, a side close to the lock lever 28, and the inside of the conveyance path 12 from the free end toward the rotation base end. A taper portion 44 that is inclined so as to protrude is provided.

  Although the taper portion 44 will be described in detail later, when the lock lever 28 interlocks and controls the movable panel 24 from the closed position to the open position, the engagement pin 28a of the lock lever 28 slides on the taper portion 44. Thus, the movable panel 24 can be opened instantly.

  One end of the movable lock claw 30 is pivotally attached to the movable panel 24 by a shaft 36 parallel to the rotation shaft 32 of the movable panel 24. The other end of the movable lock claw 30 is a free end and has a hook portion 42. Further, the middle of the movable lock claw 30 is urged in the rotation direction about the shaft 36 by the elastic pressure of the spring (tensile) 38.

  The lock lever 28 is disposed at one end in the axial direction of the drive shaft 15 of the turning roller 16 (see FIG. 1 or 2), and can be interlockedly controlled from the closed position toward the open position. Has been. One end of the lock lever 28 is pivotably mounted about the fulcrum shaft 29, and the other end is a free end. On the free end side, an engaging pin 28a as an engaging portion is planted. The fulcrum shaft 29 is fixed to the main body frame 11.

Thus, at the closed position of the movable panel 24 (position of FIG. 3), the engagement pin 28a is engaged with the movable lock claw 30 and locked.
That is, in the movable panel 24, the engaging pin 28a is engaged with the movable lock claw 30 in the closed position to form the conveyance path 12, and the engagement pin 28a is detached from the movable lock claw 30 in the open position. (See the solid line in FIG. 2).

  Further, during the turning operation, the movable panel 24 falls from its open position to its closed position by its own weight, but the movable panel 24 in the middle of dropping comes into contact with the turning page 14a that is sprung up above the turning roller 16 (FIG. 9). reference). At this time, the first and second sensors 22 and 23 detect the inclination angle of the movable panel 24 when the movable panel 24 comes into contact with the turning page 14a. A control unit (not shown) determines whether or not the page is turned based on the inclination angle of the movable panel 24 at this time.

The first and second sensors 22 and 23 are so-called long distance sensors, and the lock lever 28 is controlled to swing by a cam position motor (not shown).
FIG. 4A is a plan view of the spread printing surface of the booklet 14, FIG. 4B is a side view of the printing medium during page turning (forward turn), and FIG. 4C is a view of the printing medium during page turning (reverse turn). It is a spread side view.

  In FIG. 4A, for example, date, deposit amount, withdrawal amount, balance, etc. are printed on the printing surface of the middle page 14-1. An arrow A indicates a loading direction when the booklet 14 is loaded into the page turning apparatus 10. FIG. 4B shows an embodiment in which the turning page 14a of the middle page 14-1 is turned in the clockwise direction (arrow D direction) with the center binding position as the center (forward turn).

Further, FIG. 4C shows an embodiment in which the turning page 14a of the middle page 14-1 is turned counterclockwise (arrow E direction) with the center binding position as the center (reverse turn).
In the case of reverse turn page turning, there is a difference that the rotation direction of the turning roller 16 and the like is opposite to that in the case of normal turn page turning, but the procedure is substantially the same. A case where turn turning is performed will be described as an example.

FIG. 5 is a diagram showing a flowchart of the page turning operation (normal turn), and FIGS. 6 to 12 are diagrams showing each step of the page turning operation.
Hereinafter, the page turning operation of the present embodiment will be described based on FIGS. 6 to 12 with reference to FIG. Except for FIG. 6, illustration of the conveyance path 12 in FIGS. 7 to 12 is omitted.

  In FIG. 6, when a page turning operation start signal is output from a control unit (not shown), a transport motor (booklet transport motor) (not shown) is started based on this signal. Then, the turning roller 16 and the driven roller 17 and the conveying roller 18 and the driven roller 19 all start rotating (in the direction of arrow a). As a result, for example, the booklet 14 is conveyed in the direction of arrow A from the printer device (not shown) located in the preceding stage of the conveyance direction with respect to the page turning device 10 using the conveyance path 12 as a guide (S1 in FIG. 5).

In this case, the transport roller 18 ′ and the driven roller 19 ′ (see FIG. 2) on the front side in the transport direction rotate in the same manner to transport the booklet 14, but the description thereof is omitted.
When it is detected by a sensor (not shown) that the booklet 14 has been conveyed and has reached a predetermined turning position, the turning roller 16 and the driven roller 17, and the conveying roller 18 and the driven roller 19 sandwich the booklet 14. Stop driving the transport motor. Thereby, rotation of each roller 16-19 stops, and the booklet 14 stops in a predetermined turning position (S2 of FIG. 5).

  Next, in FIG. 7, the pressure 25 is raised in the direction of the arrow b, and the turning roller 16 and the driven roller 17, and the conveying roller 18 and the driven roller 19 are retracted from the conveying path 12. At the same time, a cam position motor (not shown) is activated. Thus, the lock lever 28 is swung in the opening direction (arrow B direction in FIG. 2), and the movable panel 24 engaged with the lock lever 28 is forcibly rotated in the arrow c direction in FIG.

As a result, the movable panel 24 is forcibly raised upward about the rotation shaft 32 (S3 in FIG. 5).
As described above, in the present embodiment, the movable panel 24 is opened before the turning operation of the turning page 14a is started, so that the inflating operation of the booklet 14 is not hindered.

  In this case, as described above, the movable panel 24 is formed with the tapered portion 44 that is in sliding contact with the engaging pin 28a of the lock lever 28 on the side portion away from the conveyance path 12 (see FIG. 3). The movable panel 24 is quickly flipped up.

  Next, when the pressure 25 protrudes and moves upward, the pressure 25 pushes up the booklet 14, and at the same time, a turning motor (not shown) is activated to start the page turning operation by the friction between the turning roller 16 and the turning page 14a. . As a result, the booklet 14 is curved so as to be convex upward, and the page 14a is further expanded (S4 in FIG. 5).

  Next, in FIG. 8, the pressure 25 is lowered in the direction of arrow e, and the turning roller 16 and the driven roller 17, and the conveying roller 18 and the driven roller 19 are retracted from the conveying path 12. Then, only the turning page 14a remains in a swelled state, and the front cover, the back cover, and other middle pages 14-1 return to flat. At the same time, a cam position motor (not shown) starts the lock lever 28 toward the home position (in the direction of arrow C in FIG. 2) (S5 in FIG. 5).

  Next, in FIG. 9, the turning roller 16 and the driven roller 17, and the conveying roller 18 and the driven roller 19 are projected into the conveying path 12. At this time, the cam position motor (not shown) starts the lock lever 28 toward the home position (in the direction of arrow C in FIG. 2) (S6 in FIG. 5).

  Further, in FIG. 9, the turning roller 16 is rotated in the direction of arrow a. Then, the swelled page 14 a is further squeezed and sprung up above the squeeze roller 16. At this time, since the cam position motor (not shown) has already started the lock lever 28 toward the home position (the direction of arrow C in FIG. 2), the movable panel 24 moves toward the closed position by its own weight in the direction of the arrow d. It falls (S7 in FIG. 5).

  Subsequently, it is determined whether or not the flip-up state of the page 14a is OK (S8 in FIG. 5). At this time, when the flip-up of the turning page 14a is OK, the turning page 14a is contained between the turning roller 16 and the movable panel 24 (see FIG. 9). For this reason, in this state (bounce-up OK), the movable panel 24 does not reach the closed position and is inclined at a predetermined angle. Thus, the detection value of the first sensor 22 is in the transmissive state, the detection value of the second sensor 23 is in the shielding state, and the jumping up is determined to be OK based on these two detection values.

  On the other hand, for example, in the case of FIG. 10, the turning page 14a is not flipped up, and the movable panel 24 is in the closed position (horizontal state). In this case, the detection value of the first sensor 22 is in the transmission state, and the detection value of the second sensor 23 is also in the transmission state, and it is determined that the flip-up failure (NG).

  In the case of FIG. 11, the movable panel 24 is lifted to a predetermined angle or more and tilted due to the rigidity of the turning page 14 a swelled in a quadratic curve. In this case, the detection value of the first sensor 22 is in the shielding state, and the detection value of the second sensor 23 is also in the shielding state, and it is determined that the flip-up failure (NG).

If the flipping up of the page 14a fails (NG), a retry process is performed (S9 in FIG. 5). Here, description of the retry process is omitted.
On the other hand, if the flip-up is OK, the process proceeds to the turn-back operation (S10 in FIG. 5).

  In this turning operation, as shown in FIG. 12, both the turning roller 16 and the driven roller 17 and the conveying roller 18 and the driven roller 19 start to rotate in the direction opposite to that shown in FIG. 6 (in the direction of the arrow a ′). . In this way, the booklet 14 is transferred in the direction of the arrow A 'opposite to the direction of the arrow A, and the page 14a flipped up is turned.

  During this time, the movable panel 24 returns to the closed position by its own weight (S11 in FIG. 5). At the falling point of the movable panel 24, the movable lock claw 30 is engaged so as to securely hold the engagement pin 28a of the lock lever 28.

Next, based on FIG. 13, the structure of the movable panel 24 and the movable lock nail | claw 30 of this Embodiment is demonstrated in detail.
The movable panel 24 has a first projection 34 projecting upward on the transport path 12 on the free end side, and a second projection projecting in the same direction between the free end side and the base end side. 35 is provided. One end of the movable lock claw 30 is pivotally attached to the first protrusion 34 via a shaft 36 so as to be rotatable. A hook portion 42 is formed at the other end of the movable lock claw 30.

  In addition, a spring (tension) 38 is mounted between the movable lock claw 30 and the second protrusion 35 in the middle of the movable lock claw 30, and the movable lock claw 30 is moved by the spring (tension) 38. The shaft 36 is biased in the rotation direction (the direction of arrow f in FIG. 13).

  The hook portion 42 of the movable lock claw 30 has an engagement surface 42a that engages with the engagement pin 28a of the lock lever 28 at the time of locking, and an inclination that extends at an acute angle on the opposite surface side across the engagement surface 42a and the tip 42b. And a surface 42c. The inclined surface 42c is a surface that collides with the engagement pin 28a of the lock lever 28 when the movable panel 24 falls by its own weight from the open position to the closed position.

  That is, when the movable panel 24 falls by its own weight from the open position to the closed position, the movable lock claw 30 retreats so that the inclined surface 42c of the hook portion 42 collides with the engagement pin 28a and separates from the engagement pin 28a. Moving. Accordingly, the movable lock claw 30 is returned to the original position by the urging force of the spring (tensile) 38 at the same time as the hook portion 42 at the front end holds the engaging pin 28 a between the movable panel 24 and the hook pin 42.

  For this reason, the movable panel 24 can be instantaneously returned to the predetermined closed position without hunting. That is, the movable panel 24 is locked so as to embrace the engagement pin 28 a by the action of the hook portion 42 having the engagement surface 42 a and the inclined surface 42 c and the spring (tensile) 38.

Next, operations of the lock lever 28, the movable panel 24, and the movable lock claw 30 during page turning will be described with reference to FIGS.
In the present embodiment, as described above, only the operation of the movable panel 24 on the rear side in the conveying direction of the turning roller 16 will be described, and the corresponding movable panel 24 ′ on the front side in the conveying direction corresponding thereto will be described. The symbol is marked with a '(dash) and its description is omitted.

  FIG. 14 shows a state where the lock lever 28 is at the home position and the movable panel 24 is at the closed position. At this time, the engagement pin 28 a of the lock lever 28 is in an engaged state held by the movable lock claw 30. At this time, the movable panel 24 is in a closed position that constitutes the transport path 12, and is locked by the engagement pin 28 a of the lock lever 28 in this closed position.

  FIG. 15 shows the positional relationship when the lock lever 28 unlocks the movable panel 24. At this time, the lock lever 28 starts to slightly rotate in the direction of arrow F about the fulcrum shaft 29. At this time, the engaging pin 28 a is detached from the hook portion 42 of the movable lock claw 30, and the movable panel 24 starts to slightly rotate in the direction of arrow G around the rotation shaft 32.

  FIG. 16A is a diagram illustrating a positional relationship between the movable panel 24 and the lock lever 28 when the movable panel 24 is opened (opened) to the maximum. Thereafter, page turning of the booklet 14 is started. When the movable panel 24 is opened, the engaging pin 28a of the lock lever 28 is slidably contacted along the taper portion 44 of the movable panel 24, and the movable panel 24 is quickly lifted up and released.

FIG. 16B is a diagram illustrating the movement locus of the engagement pin 28a when the lock lever 28 swings from the home position to the turn position in the direction of arrow G.
That is, the engagement pin 28 a is located at the tip of the taper portion 44 of the movable panel 24 at the home position, and is slidably contacted from the tip position to the proximal end side of the taper portion 44 at the turn position. As a result, the movable panel 24 is quickly flipped upward in accordance with the amount of inclination of the tapered portion 44.

In this way, as described with reference to FIG. 7, the movable panel 24 is opened before the turning page 14a expands so that the expanding operation of the turning page 14a is not disturbed.
The lock lever 28 is forcibly returned to the direction of the arrow H after the movable panel 24 is opened. Note that the movable panel 24 falls and rotates around the rotation shaft 32 by its own weight behind the lock lever 28.

17A to 17D show the operating state of the movable panel 24 after the lock lever 28 first returns to the home position.
17B to 17D, only the relationship between the engagement pin 28a and the hook portion 42 is illustrated, and other members are omitted or simplified.

  That is, as shown in FIG. 17A, the movable panel 24 drops and rotates in the direction of the arrow I about the rotation shaft 32 by its own weight so as to follow the lock lever 28. At this time, the movable lock claw 30 pivotally attached to the movable panel 24 drops and moves integrally with the movable panel 24. Then, the movable lock claw 30 approaches the engagement pin 28a of the lock lever 28 that has arrived at the home position first, and the inclined surface 42c of the hook portion 42 collides with the engagement pin 28a.

Then, a moment about the shaft 36 is generated in the movable lock claw 30 due to the reaction force P applied to the movable lock claw 30 at this time.
Due to this moment, as shown in FIG. 17B, the movable lock pawl 30 retreats away from the engagement pin 28 a about the shaft 36 against the biasing pressure of the spring 38. At this time, it is assumed that the tip 42b of the hook portion 42 is separated from the outer periphery of the engagement pin 28a by λ (lambda).

  After this retreating movement, the movable panel 24 and the movable lock claw 30 fall in the direction of arrow I by their own weight with the rotation shaft 32 as the center. Thus, as shown in FIG. 17C, the tip 42b of the hook portion 42 jumps over the outer periphery of the engagement pin 28a and falls in the direction of the arrow g.

  Next, as shown in FIG. 17D, the hook portion 42 of the movable lock claw 30 is pulled in the rotation direction (the direction of arrow f in FIG. 17D) about the shaft 36 by the biasing pressure of the spring 38. Thus, the engagement pin 28 a of the lock lever 28 is engaged (locked) so as to be held between the hook portion 42 and the movable panel 24.

  Thus, when the movable lock claw 30 falls due to its own weight, the hook portion 42 collides with the engagement pin 28a and then retreats, and then jumps over the engagement pin 28a and then securely holds it by the action of the spring 38. Include. Thereby, since it is not necessary to perform the lock operation again, the processing time can be shortened.

Thus, as shown in FIG. 14 described above, the movable lock claw 30 returns to the locked state in which the engagement pin 28 a of the lock lever 28 is held in the closed position of the movable panel 24.
According to the present embodiment, the movable lock claw 30 is pivotally mounted at one end and has the hook portion 42 at the other end and is biased by the spring 38 at the other end. In doing so, the engagement pin 28a of the lock lever 28 can be locked in one shot. Thus, the movable panel 24 is instantly locked in the closed position without hunting. For this reason, it is not necessary to perform a re-locking operation, and the processing time can be shortened.

  Further, according to the present embodiment, since the movable panel 24 is provided with the tapered portion 44, the movable panel 24 can be instantaneously opened first before the turning operation is started, and the booklet 14 swells. Can be prevented from being disturbed. In this way, since the next operation can be immediately performed, the processing time can be shortened also in this respect.

Note that the retraction speed of the movable panel 24 can be adjusted by changing the shape of the tapered portion 44 of the movable panel 24.
Thus, according to the present embodiment, a considerable time reduction (for example, about 2 seconds) can be achieved compared to the conventional case. In addition, since the success rate of page turning increases, the operator's stress can be reduced.
