[Industrial applications]

 The present invention relates to a mechanism for preventing a passbook middle sheet, a cover sheet and a spine cover from being caught in a page feed roller in an automatic page feed mechanism.

[0002]

[Prior Art]

 FIG. 7 is a front view showing a schematic configuration of a conventional automatic page-breaking mechanism and an operation of preventing entanglement. In the figure, reference numeral 1 denotes a passbook, which is formed into a booklet by binding a front cover and a back cover to a plurality of inner sheets 2 by a center hold 1a which is the center of folding. A page break roller 3 has an appropriate friction on the circumferential surface. A part of this circumferential surface is brought into contact with the middle paper 2 of the passbook 1 so that the passbook 1 as a whole does not move. By rotating the page roller 3, the inside paper 2 of the passbook 1 is turned over.

Reference numeral 4 denotes a roller provided so as to face the page-breaking roller 3, and is movable in a direction of moving away from or approaching the page-breaking roller 3. The roller 4 does not rotate during the page turning performed by moving the roller 4 in a direction approaching the page break roller 3 to bring the passbook 1 into contact with the page break roller 3 and rotating the page break roller 3. In addition, it prevents the entire passbook 1 from moving. Reference numeral 5 denotes a roller group for conveying the passbook 1, and 6 denotes a movable guide plate that serves as a guide when the passbook 1 is conveyed and retracts when turning the pages so as not to interfere with the turning.

According to the above-mentioned configuration, the passbook 1 conveyed for page break is stopped at a predetermined position where the page break roller 3 and the page to be paged face each other. Then, the guide plate 6 is opened, the roller 4 is moved in the direction of approaching the page break roller 3, and the passbook 1 is sandwiched between the page break roller 3 and the roller 4, and the page to be changed and the page break of the passbook 1 are inserted. The roller 3 is brought into contact. When the page break roller 3 is rotated in the direction of arrow A without rotating the roller 4, the page break page should be turned.

Although not shown, when the pages to be page-turned are turned in a mountain shape, the rotation of the page-feed roller 3 is once stopped and the page-feed roller 3 is rotated by a predetermined amount in the arrow B direction opposite to the above. , Remove the swelling of the pages after the page to be lifted that is lifted by the page to be paged. When the page feed roller 3 is rotated in the direction of arrow B by a predetermined amount, the page feed roller 3 is rotated again in the direction of arrow A, and the page to be page-fed is flipped up. The judgment as to whether or not the page to be changed has been flipped up is recognized from the rotation angle of a motor (not shown) that drives the page-change roller 3.

If the page to be renewed is flipped up, the swelling of the page after the page to be renewed lifted along with the page to be renewed is taken up, but at this time, the page to be renewed has not yet been lifted. It is in contact with the page-feed roller 3, and in order to prevent it from being caught, first, the passbook 1 is fed by a predetermined amount in the direction of arrow C, and the passbook 1 is moved from the contact position 3a between the page that has been flipped up and the page-feed roller 3 as much as possible. The distance of the section L to the center hold 1a is shortened and the waist of the section L is strengthened. Then, after the conveyance is stopped, the page feed roller 3 is rotated in the direction of arrow B by a predetermined amount to swell the pages after the page to be paged.

In this way, the distance of the section L from the contact position 3a between the flipped-up page and the page break roller 3 to the center hold 1a of the passbook 1 is shortened, and the waist of the section L is strengthened. Thus, the page break roller 3 is rotated in the direction of arrow B to prevent the page from being flipped up. After rotating the page-break roller 3 in the direction of arrow B by a predetermined amount and swelling the pages after the page to be changed, the roller 4 is moved away from the page-break roller 3 and the passbook 1 is again moved to the arrow direction. By conveying in the C direction, the flipped page is completely opened and sent to the next processing system.

[0008]

[Problems to be Solved by the Invention] As described above, when performing a page break, the page to be paged is flipped up, and the page after the page to be paged is lifted and lifted. Therefore, it is necessary to rotate the page feed roller 3 in the direction of arrow B, which is opposite to the direction when turning the page. However, the page flipped up for page break is still in contact with the page break roller 3, so that the section L from the contact position 3a between the flipped page and the page break roller 3 to the center hold 1a of the passbook 1 By shortening the distance, the section L becomes stiffer, and in order to prevent the flipped-up page from being caught in the page break roller 3, the passbook 1 is conveyed in the direction of arrow C for a predetermined amount and then stopped. Then, the swelling of pages after the page to be changed is taken.

As described above, when the slack of the page after the page that has been flipped up to take a page break is taken out, in order to prevent the page that has been flipped up from being caught in the page break roller 3, the passbook 1 is moved by a predetermined amount. There is a problem in that the processing speed becomes slow because the procedure is to temporarily stop after transporting and to swell the pages after the page to be changed. Also, since the page that has been flipped up to break the page is in contact with the page break roller 3, the page that has been jumped up to break the page can still be caught by the page break roller 3 even if the control is performed as described above. There is a problem that sex is left.

The present invention has a problem that the whole processing speed is slowed down in order to prevent the page that has been flipped up for page break, and that the page that is flipped up for page break is completely prevented. This was done to solve the problem that it could not be performed, and when removing the slack of the page that was sprung up to break the page, it was jumped up to break the page without reducing the overall processing speed. It is an object of the present invention to provide an automatic page break mechanism that completely prevents the inclusion of pages.

[0011]

[Means for Solving the Problems]

 In order to achieve this object, the present invention has a rotation axis parallel to the folds of a booklet-like passbook, and contacts the page to be changed at a part of the circumferential surface around the rotation axis. A page-turning roller that turns the page to be turned by turning the page-turning roller, and a roller that is provided so as to face the page-breaking roller and the passbook, and presses the page to be turned on the page-breaking roller. In an automatic page-breaking mechanism having a transporting means for transporting a book in a direction orthogonal to a fold, a means for recognizing that the page to be page-fed in a passbook has been flipped up, A means for retracting to a position where the page roller is not in contact with the page roller is provided.

[0012]

[Action]

 According to the present invention having the above-described structure, the page break roller is brought into contact with the page of the passbook to be turned, and the page break roller is rotated while the passbook is stationary to turn the page to be turned. When the page to be paged is flipped up by the page feed roller, the page that was flipped up and the page feed roller are brought into non-contact with each other, and the page feed roller is paged while the passbook is still stationary. Rotate the page in the opposite direction to when turning the page, and lift the bulge of the page after the page that was lifted along with the page to be paged. Then, the passbook is conveyed in the direction in which the fold passes through the page-break roller, so that the page that has been flipped up and retracted to break the page is turned to a position parallel to the other pages.

The operation of this embodiment will be described below with reference to the flowchart shown in FIG. First, in the initial state, as shown by the alternate long and short dash line in FIG. 1, the middle paper pressing levers 10 and 11 connect one end side thereof to the circumferential surface of the page break roller 3a and the circumferential surface of the page break roller 3b. It is located in a virtual cylinder. The passbook 1 conveyed for page break is stopped at a predetermined position where the page break roller 3 and the page to be paged face each other. Then, the guide plate 6 is opened, the roller 4 is moved in the direction of approaching the page break roller 3, and the passbook 1 is sandwiched between the page break roller 3 and the roller 4, and the page to be changed and the page break of the passbook 1 are inserted. The roller 3 is brought into contact. When the page break roller 3 is rotated in the direction of arrow G without rotating the roller 4, the page break operation is started and the page to be paged is turned (S1).

At this time, the inside-paper detecting sensor 18 detects whether or not the page to be changed is turned by a predetermined amount, and the page-break roller 3a, until the inside-paper detecting sensor 18 detects the page to be changed. Rotate 3b. When the inside paper detection sensor 18 detects a page to be changed, the page to be changed is in a mountain shape that has not been completely flipped up (S2). In S2, after the page break rollers 3a and 3b are rotated by a predetermined amount in the direction of arrow G, and if the inside paper detection sensor 18 does not detect a page to be paged, the page break rollers 3a and 3b are further rotated. Then, the pages to be page-turned are turned into a mountain, and retry is performed so that the inside paper detecting sensor 18 can detect them (S3). In S2, when the inside paper detecting sensor 18 detects the page to be page-changed, the rotation of the page-change rollers 3a and 3b is temporarily stopped, and the page-change rollers 3a and 3b are moved by a predetermined amount in the arrow H direction opposite to the above. Rotate and lift the page after the page to be lifted that is lifted by the page to be paged.

After the page break rollers 3a, 3b are rotated in the direction of arrow H by a predetermined amount, the page break rollers 3a, 3b are again rotated in the direction of arrow G to flip up the page to be page broken (S4). Here, the judgment as to whether or not the page to be changed has been flipped up is recognized from the rotation angle of a motor (not shown) that drives the page break rollers 3a and 3b, and based on this, the page to be changed should be flipped up. If judged, the rotation of the page break rollers 3a, 3b is stopped. At the same time, the inner-sheet pressing lever opening / closing solenoid 16 is driven so that one end of each of the inner-sheet pressing levers 10 and 11 is driven by the inner surface of the page-feeding roller 3a and the page-feeding roller 3b as shown by the solid lines in FIGS. The intermediate paper pressing levers 10 and 11 are opened in the directions of the arrows E and F, respectively, up to the position where they are outside the virtual cylinder that connects with the circumferential surface of the (S5). As a result, the page flipped up to make a page break comes into contact with the inside paper pressing lever 10 and does not come into contact with the page break rollers 3a and 3b. At this time, although not shown, the uppermost page after the page flipped up for page break remains in contact with the page break rollers 3a, 3b.

When the page flipped up for page break is brought into non-contact with the page break rollers 3a, 3b by the middle paper pressing lever 10, the page break rollers 3a, 3b are rotated by a predetermined amount in the direction of arrow H to break the page. The swelling of the pages after the flipped page is removed (S6). After the page break rollers 3a and 3b are rotated by a predetermined amount in the direction of the arrow H to swell the pages after the page to be paged, the roller 4 is moved away from the page break rollers 3a and 3b. The rollers 3a and 3b and the topmost page of the pages after the page that has been flipped up to break the page of the passbook 1 are brought into non-contact with each other, and the passbook 1 is conveyed by a predetermined amount in the direction of the arrow I by the conveying roller 5 or the like (S7). ). As a result, the page that has been flipped up to make a page break that is in contact with the inner-sheet pressing lever 10 is further opened, and the page that has been flipped up to make a page break is completely page-fed and becomes parallel to the other pages ( S8).

When the passbook 1 is conveyed by a predetermined amount and the page flipped up to break the page is completely opened, the inner-sheet pressing lever opening / closing solenoid 16 is driven to move one end of the page 16 as shown by a chain line in FIG. The inner paper pressing levers 10 and 11 are closed so that the side is located in a virtual cylinder connecting the circumferential surface of the page break roller 3a and the circumferential surface of the page break roller 3b (S9). Then, in order to determine whether a predetermined page break operation has been performed, the passbook 1 is moved to a position where the reflection sensor 26 for reading the page mark on the inside paper 2 of the passbook 1 and the position of the page mark on the inside paper 2 face each other. It moves (S10) and reads the page mark (S11). The page mark which is read and recognized is collated (S12), and when it is recognized that the predetermined page is not opened, the page to be newly changed and the page-change roller 3a are required to perform the page-change operation again. , 3b are conveyed to the opposite position, and the above steps S1 to S11 are repeated until it is recognized in S12 that a predetermined page is opened (S13).

At this time, in the above-described automatic page break mechanism of the present embodiment, since the inside paper pressing levers 10 and 11 are on both sides of the page break rollers 3a and 3b in the passbook 1 transport direction, as described above. Similarly to the case where the press lever 10 side makes the page flipped up for page break non-contact with the page break rollers 3a, 3b, the page flipped page for page break at the inside paper presser lever 11 side. Can be brought into a non-contact state with the page break rollers 3a and 3b, and the page break operation from the opposite direction to the above can be performed in the same procedure. As a result of the page mark collation, when it is recognized that a predetermined page is opened, the line information is confirmed (S14), and the process proceeds to the next processing system. In the above-mentioned embodiment, the middle paper is explained as the page to be changed in the drawing, but the same operation as above is performed when the cover is turned, so that the flipped page is rolled up. Can be prevented.

[0026]

[Effect of the device]

 As described above, the present invention has a rotation axis parallel to the folds of a booklet-like passbook, and contacts the page to be changed at a part of the circumferential surface around the rotation axis. A page-break roller that turns the page to be turned by rotating, a roller that is provided opposite to the page-break roller with a passbook sandwiched between them, and presses the page that should be page-breaked against the page-break roller, and folds the passbook. In the automatic page-breaking mechanism having a conveying unit that conveys the page in a direction orthogonal to, a unit for recognizing that the page of the passbook to be changed has been flipped up, and And means for retracting it to a position where it is in a non-contact state.

As a result, when removing the swelling of the pages after the page that has been lifted to lift the page and that has been lifted to break the page, As a means for retracting to a position where it is not in contact with the roller, the inside paper pressing lever lifts the page that has been lifted to make a page break in contact with the page-break roller, and the page that has been jumped to make a page break with the page-break roller. Since the page is not contacted, the page break roller is rotated at the position where the page to be paged is flipped up without changing the position of the entire passbook, and the swelling of the pages after the page flipped up to page break. Therefore, the processing time for the entire page break operation can be shortened as compared with the conventional method.

Since the page flipped up to break the page with the page break roller is not in contact with the page break roller, the page break roller is turned over and rotated in the direction opposite to the flipping operation to perform the page break. When removing the swelling of the page after the flipped page, there is an effect that it is possible to eliminate the possibility that the page that has been flipped up to be turned into a page break roller may be caught.
