Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a page turning device that turns pages of a booklet such as a passbook one by one in a desired direction.

2. Description of the Related Art Conventionally, when pages that make up a booklet such as a passbook are mechanically turned over, a page with a strong rigidity (for example, a hard paper like the cover page) is used to prevent multiple pages from being turned at once. , For pages with weak stiffness (for example, some soft paper such as medium paper), change the flipping position, or use a material with a high friction coefficient such as a rubber roller to finely control the pressing pressure of the folding member. I was doing it.

However, in this conventional technique, it is necessary to adjust the turning position of the booklet and the pressing pressure of the turning member in order to prevent the plural sheets from being turned at once. It was necessary to individually take into account the above elements, and the control of the device and the mechanism itself became very complicated.

Therefore, the same applicant first turned over the pages of the booklet on the table surface by pressing the rear end of the booklet against the table surface from the upper surface and pushing the front end of the booklet toward the rear end side. Bending the entire booklet, striking the upper surface of the curved booklet while flattening the top page of the booklet while flattening other pages against the table surface, curving the top page of the booklet The page of the booklet is pushed to the rear end side while being flattened, and the force of pressing the rear end of the booklet against the table surface from the upper surface is released. A transport roller, a pair of upper and lower second transport rollers that are separated from the first transport roller by a distance that is slightly shorter than the width of the page of the booklet, and a position sensor that detects the position of the booklet. A table surface that guides the booklet between the upper and lower rollers of the first transport roller and the second transport roller, a page turning member that acts on the rear end of the booklet, and separates the top page of the curved booklet from other pages. Therefore, a member for tapping a curved booklet from the upper surface and a page-turning device for turning pages of the booklet are disclosed (Japanese Patent Application No. 1-209466).

[Problems to be Solved by the Invention] The above-mentioned applicant's proposal succeeds in making the complicated mechanism of the page turning device before that very simple and at the same time surely achieving the page turning of the standard paper quality booklet. did. However, in the case of a booklet with a very large stiffness of paper or a booklet with a very large coefficient of friction between pages,
The above proposal of hitting the curved upper surface of a booklet with an appropriate amount of curvature to separate the top page to be flipped from other pages cannot be completely achieved, and a slight complete separation operation is performed. It turned out that there is no such thing or that a plurality of sheets are turned over at the same time. It was also necessary to hit the curved top surface of the booklet twice or three times.

The present invention solves this problem.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is to make a page-turning booklet, so that the page-turning work can be easily performed, and thereafter, the booklet can be turned to the page-turning roller and the other side. A means for bending an appropriate amount with the conveying roller and then slightly moving the page-turning roller on the facing side forming the curve up and down for a minute time is provided.

Working In the present invention, the top page of the booklet to be turned is separated from other pages prior to the turning operation, so that the booklet is formed between the page-turning roller on the facing side of the booklet and the conveying roller on the other side. The page turning roller is bent by an appropriate amount, and the page turning roller is slightly moved up and down for a minute time. For this reason, the top page held by the page turning roller remains in that position due to the frictional force between the page turning roller and the page turning roller despite the vertical movement of the page turning roller for a minute time. The pages below the eyes return from the curved state to the flat state with their own waist in a short time, and thus the separation between the pages that are turned up and the other pages can be achieved.

Embodiment FIG. 1 to FIG. 12 are operation diagrams showing a first embodiment of the present invention. The device of the present invention comprises a pair of left and right units that operate in generally the same manner. That is, each unit includes a pair of upper and lower transport rollers 20, 21; 22:23, and an upper transport roller 20,
It consists of page-turning rollers 24, 26 above 22. The transport rollers 20, 21; 22 and 23 may each be composed of a single long roller, or may be a plurality of rollers having a narrow width and arranged at regular intervals. In contact with each other, when the booklet 36 is conveyed between the conveying rollers, the lower conveying rollers 21 and 23 are elastically held so that they can descend to the same plane as the table surface 38. The rollers 20 to 23 are simultaneously driven by a known motor or the like. Similar to the transport rollers, the page turning rollers 24 and 26, each having a single long roller or multiple narrow rollers arranged at regular intervals, have a built-in one-way clutch that can rotate only in the directions of arrows 25 and 27, respectively. It is mounted on levers 32 and 34 that swing around the rotation center shafts 28 and 30.

Position sensors 40 are provided in the upper and lower parts of the table surface 38 in the vicinity of the left side transport rollers 20 and 21. In the figure, only the light emitting side is shown and the light receiving side is omitted.

As shown in FIG. 1, the booklet 36 inserted into the insertion portion between the left side transport rollers 20 and 21 rotating in the directions of arrows 42 and 43.
Moves to the right on the table surface 38 and is further advanced to the right by the right-hand side transport rollers 22 and 23 which are also rotating in the directions of arrows 44 and 45.

The rear end of the booklet 36, that is, the end on the facing side is the left transport roller 2
When passing between 0 and 21 and passing over the sensor 40, the sensor 40 operates to stop the rotation of the right side transport rollers 22 and 23 and stop the movement of the booklet 36.

Then, as shown in FIG. 2, the left page-turning roller
24 rotates clockwise around the lever rotation center axis 28 and contacts the table surface 38. Booklet 36 now stopped at this time
The rear end of the page turning roller 24 is controlled by the position sensor 40 so as to be located about 3 to 4 mm to the right of the table surface grounding point of the page turning roller 24. The page turning roller 24 is formed of a material having a high coefficient of friction such as rubber or by attaching these materials on the surface, and is arranged in a direction orthogonal to the conveyance direction of the booklet.

Then, as shown in FIG. 3, the conveying rollers 22 and 23 are rotated in the direction opposite to the arrows 44 and 45 while holding the booklet 36, and the booklet 36 is pushed back to the left by about 20 mm. The trailing edge of booklet 36 is 3-4m
m The booklet 36 for hitting the page turning roller 24 on the left side and being pushed further to the left side is curved upward as shown in the figure. This is a habitual action to make it easier to turn pages. The curling operation is particularly required for turning over a cover such as a new passbook.

Next, as shown in FIG. 4, the right side conveying rollers 22 and 23 are rotated in the directions of arrows 44 and 45 to convey the booklet 36 rightward by about 20 mm, and at the same time, the left page turning roller 24 is rotated leftward and raised. Return to the original position shown in FIG.

Next, as shown in FIG. 5, the right side transport rollers 22 and 23 are rotated in the direction opposite to the arrows 44 and 45 to transport the booklet 36 leftward by about 10 mm.

Then, as shown in Fig. 6, the left page turning roller
The 24 is again rotated clockwise to the table surface, and the rear end of the booklet 36 is pressed against the table surface 38 with a constant pressure. At this time, it is preferable that the left page turning roller 24 presses the rear end of the booklet 36 about 3 to 4 mm to the right.

Then, as shown in FIG.
While pressing the table surface 38 with
The booklet 36 is moved to the left by about 5 mm by rotating 23 in the direction opposite to the arrows 44 and 45 to bend the booklet 36 upward, and the rollers 22 and 23 are stopped at that position.

After that, as shown in FIG. 8, the roller 24 pressing the rear end of the booklet 36, that is, the end on the facing side to the table surface 38 is raised for a minute time. It is known that about 50 ms is suitable for this minute time in the case of a cover such as a passbook having a firm surface. However, this time will depend on the paper quality.
The top page of the booklet 36, which tries to turn over when such a floating action of the roller 24 occurs, is the left page turning roller 24.
It is held in the state shown in Fig. 7 due to friction with and is curved, but the second and subsequent pages are the rollers due to the waist of the paper itself.
Slide under the table 24 to the left on the table surface 38. Here, the right-side page turning roller 26 is arranged in the direction orthogonal to the feeding direction of the booklet 36 like the left-side page turning roller 24. Also, these left and right rollers 24, 26
Is preferably driven about the central axis of rotation 28, 30 by a solenoid linkage. It is appropriate that the amount of rise of the roller 24 during the minute time is about 3 to 5 mm, but this also depends on the paper quality as with the above time, and further depending on the above time and the friction coefficient of the roller 24. Obviously it depends. By the operation shown in FIG. 8, the top page is separated from the second and subsequent pages below it.

Next, as shown in FIG. 9, the left page turning roller 24 is immediately lowered to press the rear end of the booklet 36 again. Now, only the top page of the booklet 36 is sandwiched between the left-side page turning roller 24 and the right-hand side conveying rollers 22 and 23 to maintain the curved state, and the second and subsequent pages become flat, The division of the page to be turned over is completed.

Then, as shown in Fig. 10, the left page-turning roller
While keeping the top page of the booklet 36 by 24, the left and right transport rollers 20, 21; 22, 23 are moved to the arrows 42, 43; 4 in FIG.
Rotate in the opposite direction of 4, 45 and return the booklet 36 to the left about 40 mm except the top page. For this reason, the top page is further separated from the second page of booklet 36.

After that, as shown in FIG. 11, the booklet 36 is pushed back further to the left to form a loop on the top page, and at the same time,
As shown in FIG. 12, set the left page turning roller 24 to the first position.
Pivot up to the position shown and flip up the top page forming the loop. Left transport roller 20, 21
Is operated, the booklet 36 is ejected from the insertion portion with one page turned over.

In the above-mentioned embodiment, an example in which the cover of a booklet having a comparatively strong stiffness is turned over is described, but the rising time of the turning roller in FIG.
It has been found that turning the middle paper can be achieved in the same manner by setting the time to about ms. This is because the inner paper is less stiff than the front cover, so if it had risen as much as 50 ms, the time it took for the turning roller to rise was too long, and as a result, the page surface of the inside paper was the friction surface of the turning roller 24. The reason is that they cannot be separated properly because they are out of alignment.

In the above embodiment, the page turning roller on the right side
26 is doing nothing. However, as is apparent to those skilled in the art, the front end of the booklet is transported to the flipping position,
By turning the left and right turning rollers in the order of rotation and the direction in which the booklet is conveyed at the time of turning, the reverse operation of the inside paper can be performed in the same way by turning the cover and the inside paper. In such a case, the turning roller 26 can perform the same operation as the turning roller 24 described above.

FIGS. 13 to 19 show a second embodiment of the present invention. The difference from the first embodiment is that a turning member is provided in place of the left page turning roller 24 in FIG. It is substantially the same as that of the first embodiment.

Next, the operation of the second embodiment will be described.

FIG. 13 is substantially the same as FIG. 5 of the first embodiment, and a booklet 58 such as a passbook inserted between the upper and lower transport rollers 50, 51 on the left side is formed by arrows 55, 57 and arrows 64, 65. The left side conveyance rollers 50 and 51 and the right side conveyance rollers 52 and 53 that rotate in the direction convey the sheet to the right. The booklet 58 is stopped at a predetermined position by detecting the rear end of the booklet 58 by the position sensor 62 and stopping the right side conveyance rollers 52, 53.

Next, as shown in FIG. 14, the page turning member 54 descends on the rear end of the booklet 58, and the booklet 58 is placed on the table surface 60.
Keep strong pressure against. The page turning member 54 is preferably formed of urethane rubber or the like having a high coefficient of friction, and may have a roller shape as in the first embodiment.

After that, as shown in FIG. 15, the right transport rollers 52, 53 rotate in the direction opposite to the arrows 64, 65 to move the booklet 58 to the left. Therefore, the booklet 58 is curved upward as in FIG.

Next, as shown in FIG. 16, the right side transport rollers 52 and 53 are stopped, and one end of the booklet is strongly supported by these rollers. In this way, the booklet 58 is held in an upwardly curved state between the roller and the page turning member. In this state, the page turning member 54 is raised for a minute time (see FIG. 8). For this reason, the top page of the booklet 58 maintains the curved state due to the friction of the page turning member 54, but the second and subsequent pages extend flat on the table surface 60 due to the waist of the page itself.

Then, as shown in FIG. 17, the page turning member 54 is immediately lowered, and the rear end of the booklet 58 is pressed again by the member 54 (see FIG. 9).

After that, as shown in FIG. 18, the left and right conveying rollers 50, 51;
Rotate in the direction opposite to 5, 57; 64, 66 to push the booklet 58 toward the insertion port side. This causes the top page of booklet 28 to have a larger curvature.

Then, as shown in FIG. 19, when the page-turning member 54 is raised, the booklet with the top page turned over
58 is pushed out from the insertion port.

The operation shown in FIGS. 13 to 19 shows the turning of the cover of the booklet, but the turning of the inner sheet can be achieved by the same procedure.

A solenoid can be used to actuate the page turning member as in the first embodiment.

In the above embodiment, the distance between the left and right page turning rollers is set to be slightly shorter than the width dimension of the page of the booklet, and the left and right page turning rollers are positioned so that they can act simultaneously on the trailing edge and the leading edge of the booklet. Has been. Further, although the position sensor is described as detecting the rear end of the booklet, the position sensor may detect the front end depending on the booklet to be handled.

20 and 21 are schematic views of an apparatus for activating the page turning means 32, 54 of the first and second embodiments, respectively.
The vertical movement of a minute time in Fig. 16 is performed at the same time.

In FIG. 20, one end of an L-shaped arm 74 that rotates around a shaft 72 is connected to the solenoid 70, and one end of a lever 76 is pivotally attached to the other end of the arm 74. The other end of the lever 76 is pivotally attached to the lever 32 by a pin 78. The spring bearing 80 is attached to this pin 78.
Is provided. A spring 82 is held between the spring bearing 80 and the lever 32. Then, the roller 24 is lowered when the solenoid 70 is attracted, and is raised when it is extended. Spring 82
Is a loosening action when the roller 24 contacts the page surface, and at the same time, when the solenoid 70 is extended, the force pressing the entire page of the booklet is reduced, but the page on the book to be turned and the roller 24 are It acts to hold the contact of. This surely achieves the separating action of FIG.

21 has a structure similar to that of FIG. 20, and the lever 84 is directly connected to the turning member 54. In FIG. 21, the spring 86 has the same function as the spring 82 in FIG.

EFFECTS OF THE INVENTION According to the present invention, it is possible to easily perform front cover turning and middle paper turning by the same mechanism without changing the page turning position and pressing pressure. Therefore, the control and mechanism of the device can be remarkably simplified as compared with the conventional one.

In addition, even on relatively stiff pages, accurate turning can be performed without requiring multiple operations, and even on pages with weak stiffness, the floating time or floating of the turning roller or turning member that holds the curved state The electronic control of the distance etc. made it possible to quickly and surely turn pages one by one.
