[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing the entire bookbinding apparatus of the present invention. As shown in FIG. 1, the bookbinding apparatus of the present invention includes a bookbinding unit 100 and a booklet separating unit 300 for separating bound booklets. Paper 1 such as a form paper is supplied by a first conveyor 29 connected in front of the bookbinding apparatus, and is accumulated on the lower surface plate 10B of the bookbinding unit. A recognition code indicating the front cover, a sorting code, and the like are printed on the cover of the form, and are used in a later process of separating and sorting the booklet. The bookbinding unit performs paper alignment and back glue application at the bookbinding unit. The bookbinding apparatus performs a paper alignment mechanism for stacking paper and vibrating the collected paper to align the paper, and performs a back adhesive coating on the side of the paper after the paper alignment. It has a gluing unit. The booklet separation unit transports the paper,
The booklet is separated while checking the type of paper, the recognition code for identifying the cover of the booklet, the sorting code, and the number of sheets. In addition, a control unit 5 for smoothly operating the entire device of the present invention.
00 is added.

FIG. 2 is a perspective view showing a bookbinding apparatus according to the present invention. In this figure, the bookbinding unit 100 is shown in a vertical position at the time of applying the back glue. After aligning the sheets, the bookbinding unit 100 rotates 90 ° from the initial horizontal state and stands up to the vertical position state in FIG. In this state, the sheet stack 1 is supported by being sandwiched between the side plate 10B (which functions as a lower plate in the horizontal state) and the side plate 10A. The gluing unit 20 stands by at a position where the glue can be applied to the lower surface of the paper when the bookbinding unit is at the vertical position, and moves along the lower surface of the paper to apply the back glue. After applying the back glue, the bookbinding apparatus returns to the original horizontal position again, and pushes the back glued sheet stack 1 'to the booklet separating unit 300 by the pusher 28 (FIG. 1).
And is conveyed by the second conveyor 30.

Next, the operation of the bookbinding unit 100 will be described in more detail with reference to the drawings. FIG. 3 is a perspective view illustrating the operation of the bookbinding unit. In FIG. 3A, the bookbinding unit is in a state of waiting for a sheet stack 1 such as a form sheet to be supplied by a conveyor or the like. In this state, the side plate 10A is located above and has not yet supported the sheet. Next, when the loading of the paper is completed, the bookbinding unit moves to the lower surface plate 10 serving as the bottom side.
B, incline so that the intersection C of the side plates 10C and 10D is the lowest point (FIG. 3B). When a predetermined inclination angle is reached, the bookbinding apparatus stops at that position, and vibrates the lower surface plate 10B or the side plates 10C and 10D to the left and right so that the side edges of the irregularly stacked sheets abut on the side surface plates, thereby causing both sides. Perform the operation of aligning the surfaces. During this operation, the side plate 10A is in a standby state obliquely upward, but when the paper alignment is completed, it descends in the direction of the arrow shown by the dotted line to press and support the paper stack 1.

Next, the operation at the time of applying the back glue will be described. After the side plate 10A descends and clamps and supports the aligned paper sheet with the lower surface plate 10B, the entire bookbinding apparatus rotates 90 ° from the initial horizontal position to be in a vertical state. At this time, the bookbinding apparatus may temporarily return to the horizontal state from the paper alignment angle position and return to the vertical state. At the time of applying the back glue, the side plate 10C is rotated by 90 ° or 180 ° from the initial position about the lower side of the side plate 10B as an axis to come off, exposing the back glue application surface of the paper stack 1 (FIG. 3C).

The gluing unit 20 is movable in parallel along the lower surface of the exposed paper stack, and
The adhesive in the glue tank is applied to the back of the paper stack by 3 or the like. The hot melt or water-soluble adhesive 22 filled in the glue tank 21 is applied to the lower surface of the sheet assembly by a rotating glue roller 23. In this case, it is preferable that the gluing unit itself moves on the lower surface of the sheet along the rail, but the binding apparatus may move if possible. After application of the back glue, the bookbinding apparatus makes 90 ° rotation around the lower side of the side plate 10B.
It rotates and returns to the horizontal basic posture position of FIG.

FIG. 4 is a top view for explaining the gluing unit. The gluing unit has a roller 23 (and preferably a roller 24), and the doctor blade 25 makes the amount of glue on the roller 23 uniform. When a hot melt adhesive is used, the glue tank 21 needs to be provided with a heating device. The entire gluing unit can be run on the rail 27 by a running device below the unit. Reference numeral 26 denotes a doctor blade holder. In order to adjust the contact between the sheet and the roller, a mechanism for moving the entire gluing unit up and down by a small interval is required.

The coating roller is a roller made of a gravure or intaglio plate and is about 10 μm
From 2 mm to 2 mm. In the case of a hot-melt type adhesive, when the temperature is raised to a high temperature, the adhesive force increases and the strength increases. It is desirable that the strength of the return form or the like, which is one object of the present invention, is not increased too much since the form is separated and used after binding. The roller 24 is for scraping off excess glue after the spine glue is applied to flatten or uniform the glue amount. In addition, it can also serve to adapt the paste to the paper surface.

As shown in FIG. 1, the paper aggregate 1 ′ having the back glue is pushed out to the booklet separating section 300 by the pusher 28, but the conveyor 30 is skewed in the pushing direction of the pusher 28. Since it is installed, it is sent to the booklet separating apparatus while being pressed against the guide plate 31, and can be stopped at a predetermined position where the booklet separating apparatus can start the page turning operation. The table surface of the conveyor and the table surface of the booklet separation device should be on the same horizontal plane, and at the position where the sheet stack 1 ′ is stopped, about half of the area is on the conveyor and the half is on the table of the booklet separation device. Then, the conveyance of the sheet stack by the conveyor and the stop at the predetermined position can be performed by the same operation.

FIG. 5 is a perspective view illustrating a booklet separating apparatus. The booklet separating device of FIG. 5A includes a table 40 on which a booklet is placed, a booklet holder 32, a page turning device 41,
It comprises a wedge device 42, a paper knife 43, and a rail 44 to which the paper knife is attached. Back-solidified paper stack 1 placed on table 40
′ Is lightly pressed from above by the booklet retainer 32, and is prevented from swinging back and forth and left and right. In addition, as described above, it is preferable that the table has a structure combined with the conveyor device. When the page turning device can open the gap between the pages sufficiently large, the wedge device is omitted and the paper knife is directly inserted into the gap as in the booklet separating device of FIG. 6B. Is also good.

The page turning device 41 is also referred to as a sheet number calculator, and is a corner 1 of a sheet aggregate 1 ′ having a back glue.
In step c, the pages are turned one by one from the bottom of the sheet and the number is counted. In addition to counting the number of sheets, the page turning device can also recognize the type of sheet, a recognition code indicating that the cover is a cover sheet, a sort destination code, and the like by using a barcode or the like.
Although this type of device is known to have various mechanisms, a page turning device used in the present invention will be described just in case.

FIG. 6 is a diagram for explaining a page turning apparatus and its operation. FIG. 6A is a conceptual diagram showing a cross section of the page turning device, and FIG. 6B is a diagram for explaining the operation thereof. First, the page turning device is shown in FIG.
And a wiper pin 412 orbiting around the suction blade. The suction blade is formed in a flat pipe body, and an upper surface thereof is provided with a suction port 413 for sucking a paper sheet. One end of the suction blade is closed and the other end communicates with the suction pump. In addition, the suction blade needs to count the number of pages of the paper sheet and rise, so that it is connected to an elevator mechanism that rises in conjunction with the counting of the number of pages. The wiper pin also needs to be raised integrally with the suction blade and is connected to the elevator mechanism or connected to the suction blade. These elevator mechanisms are omitted in FIGS.

The operation will be described with reference to FIG. 6B. First, as shown in FIG.
When the upper surface of the paper sheet comes into close contact with the lowermost surface of the set corner 1c of the paper sheet, the paper sheet is automatically sucked by vacuum, and the wiper pin 412 starts rotating. Next, as shown in (2), the blade is inclined at a certain angle to form a gap between the blade and the second sheet, and the wiper pin enters around the gap. next,
In the state (3), before the blade returns to the horizontal state, the pin moves downward and starts to pull the corner 1c of the paper sheet downward. In the state (4), the pin moves to the lower side of the blade, and the first paper is wound on the lower side of the blade.
The blade then begins to attract the next paper. Thus,
In the state of (5), the first sheet is completely moved to the lower side of the blade, and subsequently enters the next cycle and starts counting the second sheet.

In this way, the page turning apparatus performs counting at the same time as turning a page. In the booklet separating apparatus used in the present invention, the page turning apparatus counts a predetermined number of pages or outputs a specific recognition code. Upon confirmation, a wedge is projected and inserted from the wedge device 42 into the gap between the paper sheets formed by the wiper pin and the suction blade, further expanding the gap between the paper sheets created by the page turning device. Then, after that, a paper knife is inserted into the enlarged gap, and at the same time as the paper knife is inserted, the paper knife travels along the back glue portion 1b in a direction parallel to the paper surface to cut the back glued portion. is there. The paper knife 43 is mounted on a rail provided in parallel with the back glue surface of the paper aggregate having the back glue solidified, and travels.

To ensure that the paper knife is inserted into the gap between the paper sheets, the angle of attachment of the paper knife to the rail is such that the tip of the paper knife (the page turning device side) is inserted first between the paper sheets. θ needs to be an angle within 90 °. It is also necessary to consider the shape of the paper knife. The paper knife only functions to separate the booklet, that is, the part that cuts the back glue, that is, the part close to the rail, and the other part functions only to cut the paper sheet. It is not necessary that the whole work as a sharp knife. Rather, doing so would cause unnecessary cutting of the paper sheet and hinder the work. The rail 44 does not necessarily have to be a track-shaped one, but any mechanism capable of attaching a paper knife is sufficient. The rail 44 is a chain-shaped or piston-shaped mechanism that reciprocates or revolves. Is also good.

When the paper knife returns to its original position after cutting the back glue, if the knife completely cuts the back glue and passes through the block, the knife removes the block. Since the paper knife cannot pass through and return, the paper knife rotates a predetermined angle (θ) so as to be parallel to the rail, that is, returns to its original position in a state where it is folded and parallel to the rail, and again. Predetermined angle (θ)
An operation of rotating and returning to the initial state is required.

FIG. 7 is a flowchart for explaining the operation of the bookbinding unit. In S1, the sheet is placed on the supply conveyor 29. At this time, it is determined whether or not the bookbinding unit is processing (S
2) If the processing is in progress, the conveyor stops and waits; if not, the conveyor is started (S3). After the paper is placed, the lower surface plate 10B is inclined obliquely so that the point C becomes the lowest point, stops at a predetermined position, and starts the vibration of the paper aligning device (S4).

After the paper is placed, the bookbinding apparatus counts the elapsed time, and determines whether a predetermined time has elapsed after the paper has been conveyed to the bookbinding unit (S5). If the predetermined time has not elapsed, the vibration continues, and after receiving the signal after the predetermined time has elapsed, the lower surface plate 10B stops the vibration (S
6). At the same time, the holding plate 10A descends to clamp and support the sheet stack 1 (S7).

The side plate 10C moves to the back of the lower plate 10B to expose the lower side surface of the sheet stack (S8). The entire paper aligning apparatus is rotated so that the surface on which the side plate 10C was located is the lowermost surface, and the side plate 1 is a lower plate in a horizontal state.
0B and the holding plate 10A are erected (S9). The gluing unit moves along the lower surface of the exposed paper stack to perform gluing (S10).

After gluing, the bookbinding apparatus counts the elapsed time, and determines whether a predetermined time has elapsed (S11). If the predetermined time has not elapsed, the drying is continued.
0C returns to the original position (S12), and lower surface plate 10B returns to the original horizontal position (S13). After that, the holding plate 10A is opened (S14) and moves up, and the bookbinding apparatus returns to the initial state.

Next, the operation of the booklet separating section will be described. FIG. 8 is a flowchart illustrating the operation of the booklet separation unit. After adjusting the lower surface plate 10B of the bookbinding apparatus and the conveyor 30 to the same plane level (S15), the bookbinding unit determines whether or not the booklet is being processed by the booklet separating apparatus (S16).
If the processing is being performed, the pusher 28 stops and waits. If the processing is not being performed, the pusher operates to transfer the back glued paper 1 'to the conveyor 30 (S17). The sheet is conveyed to the booklet separating apparatus by a conveyor (S18), and it is checked whether or not the conveyance is completed (S19). Then, the holding plate 32 is lowered to clamp the sheet (S20).

In the booklet separating apparatus, the flowchart is divided into two paths. Route (A) is a wedge device 42
Is used, the page turning apparatus starts page turning (S21), and when it is determined that it is time to separate (S22), a wedge is inserted (S23). After the gap between the paper sheets is enlarged by the inserted wedge, a paper knife is inserted (S2).
4) The back glue is cut. Thereafter, the wedge is stored (S25), and separation of one unit of the booklet is completed (S2).
6). The booklet separating device can detect that the booklet separation has been completed by the page turning device, and when it has detected that the booklet separation has been completed (S27), the pressing plate 3
2 rises (S28), and the separated booklet bundle is removed (S29). The path (B) shows a flowchart of the booklet separating apparatus without the wedge device 42, and the path (A)
In comparison with the above, the process of inserting the wedge (S23) and the process of storing the wedge (S25) are omitted.

The control device 500 controls the entire bookbinding apparatus of the present invention, and for example, checks the processing status of the bookbinding unit when feeding sheets to the bookbinding unit (S2), and checks the elapsed time after the sheet is conveyed. Recognition (S5), recognition of elapsed time after gluing (S5)
11), check the processing status of the booklet separation unit (S16), check the transport status to the booklet separation unit (S19), check the timing of booklet separation (S22), and confirm the completion of booklet separation (S16).
27). These confirmations and recognitions are made by transmitting data and data of predetermined sensors for monitoring the apparatus and predetermined set values to the control apparatus and transmitting control signals.
