Abstract

PROBLEM TO BE SOLVED: To align sheets such as a document and paste them by using the same device to bind them into a book by providing a paper alignment mechanism which aligns a paper collection body by giving the vibration to it and a pasting unit which pastes a side face of the paper collection body which is exposed. SOLUTION: A whole paper alignment mechanism starts to tilt when loading of sheet is completed in such a manner that point C which is an intersection of faces of platelike bodies 10C, 10A, and 10B becomes the lowermost point, and the lower face plate 10C vibrates after the mechanism stops at the set position to start the paper alignment operation. Upon completion of paper alignment, a pressing plate 10D lowers to press a paper collection body 1. Furthermore, the side face plate 10B travels in such a manner that a side face of the paper collection body 1 is exposed. Next, when the whole paper alignment mechanism is erected perpendicularly in such a manner that a side where the side face plate 10B existed becomes a base, a pasting unit 20 is arranged at a position along the base and travels along a lower side face of the sheet 1 which is exposed to paste it.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a mechanism for applying a vibration to a sheet stack as a unit sheet to align the sheets, and applying a glue to one side of the sheet stack after the sheet alignment to bind the book. The present invention relates to a bookbinding apparatus having a gluing unit to be in a state. However, as a specific application, it is suitable as a form processing device handled in a bank, an insurance business, etc., and in these industries, the back of a return form processed on that day and separated for each unit is aligned. It is the most suitable as a device for compacting.

[0002]

2. Description of the Related Art In a business such as a bank and an insurance business, various forms are handled.
In order to settle the bills between the head offices, the work handled on the day is organized and sent to the corresponding branch or head office. This type of form is called a return form, and is a daily routine in which it is essential to process the form handled on the day of the day. However, the amount of forms to be handled and processed is enormous, and it is not easy to manually sort the separated forms one by one. In such a case, in the related art, after the forms are aligned by a paper aligning machine, the sheets are glued and bound by a gluing device, and then the sorting operation is performed. However, since the paper aligning machine and the gluing device are not integrated, workability is poor and there is a problem that a large space is required for the device. Therefore, the present invention performs such paper-sheet alignment, and
It was completed with the idea of performing back gluing with the same device.

[0003]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the gist of the present invention is to provide a sheet aligning mechanism for aligning a sheet stack by vibrating a sheet stack placed on a lower plate, A mechanism that presses the aligned paper stack with a plate-like body, moves the side plate on the lower surface side after the paper alignment, and exposes the side of the stack of paper, and glues the exposed side of the stack of paper. And a gluing unit for performing the bonding. With such an apparatus, the separated paper can be aligned and bound easily.

[0004]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the entire bookbinding apparatus of the present invention. As illustrated in FIG.
The bookbinding apparatus of the present invention includes a paper alignment mechanism 10 for placing and aligning paper 1 such as a form paper, a gluing unit 20, and a conveyor 30 as required. The paper alignment mechanism 10 has a lower surface plate 10C serving as a bottom side thereof, and side surface plates 10A and 10B serving as side surface portions, and is located on the paper alignment mechanism 10 in a separated position before paper alignment. A holding plate 10D is further provided. The paper alignment mechanism 10 vibrates the lower surface plate 10C back and forth and left and right to make the side edges of the irregularly stacked paper abut against the side plates 10A and 10B to align both side surfaces.

The gluing unit 20 applies hot melt or a water-soluble adhesive 22 filled in a glue tank 21 to the side surface of the sheet stack by a rotating gluing roller 23. In this case, the gluing unit itself may move along the side of the paper or the gluing unit may be fixed, and the paper alignment mechanism may move on the gluing unit.

[0006] The conveyor device 30 is for transporting the bound paper to the next process, and is provided as necessary. In FIG. 1, the paper 1 to be bound is shown by a dotted line, and the glued and bound paper stack 1 ′ is transported in the direction of the conveyor device 30. In order to transfer the bookbinding after gluing to the conveyor device, it is assumed that a device for extruding the sheet stack toward the conveyor device is provided. The conveyor device may be further provided in a stage prior to stacking the cut sheets in the paper alignment mechanism.

Next, the paper alignment mechanism will be further described with reference to the drawings. FIG. 2 is a perspective view illustrating the operation of the paper alignment mechanism. FIG. 2A shows the paper alignment mechanism 1 in an operation start state.
0 is shown. The paper 1 to be bound is placed on a plate-shaped body serving as the lower surface plate 10C of the paper alignment mechanism in a horizontal state, with the front and back sides, the long side, the short side, etc., aligned. During the placement operation, the paper alignment mechanism stops operating. Next, when the loading of the paper is completed, the entire paper alignment mechanism is moved to the plate-like body 10.
The tilting is started so that the point C, which is the intersection of the planes of C, 10A, and 10B, is the lowest point, and after stopping at the set position, the lower surface plate 10C vibrates to start the paper alignment operation (FIG. 2).
(B)). In FIG. 2, the side plates 10A and 10B are shown as flat plates for simplicity of illustration.
As a shape like a letter, it is possible to prevent the sheet from falling during vibration.

When the paper alignment is completed, the holding plate 10D descends to hold the sheet stack 1. Further, the side plate 10B
Move to expose the side surface of the paper stack. Since the pressing plate presses the paper strongly against the lower plate, the paper does not fall. The side plate 10B may move behind the lower plate 10C or may move to another side. Next, when the entire paper aligning mechanism stands upright so that the side where the side plate 10B was located becomes the bottom side, the gluing unit 20 is disposed at a position along the bottom side and extends along the lower side surface of the exposed sheet 1. The gluing unit 20 moves to perform gluing (FIG. 2C). After a certain period of time and the adhesive has dried,
As the side plate 10B returns to the initial position, the paper alignment mechanism returns to the initial horizontal state. The holding plate 10D for holding the paper is also released, and the bookbinding is completed. The bound paper stack 1 'is extruded in the direction of the conveyor device 30 (FIG. 2).
(D)).

FIG. 3 is a perspective view illustrating the paper alignment mechanism. The paper alignment mechanism is placed on a support base 11 that supports the entire
The frame and the lower plate 10C are attached to a frame 13 that rotates by a predetermined angle around the shaft 12, and the frame and the lower surface plate 10C are rotatable by a rotation shaft (not shown) (rotation shaft perpendicular to the placed paper surface). A vibration source 14 such as an eccentric cam is provided in the support base 11, and transmits vibration to a lower plate 10 </ b> C via a rod body 15. Therefore, when the paper alignment mechanism performs paper alignment with the point C as the lowest point, the frame 13 is rotated by the shaft 12 after the lower surface plate 10C rotates by 45 °, and the point C is set as the lowest point, and then the vibration is performed. To start. The gluing unit 20 is installed at a position where the lower surface plate 10C stands upright with the side plate 10B horizontal. A power source for the rotation of the lower surface plate 10C and the rotation of the frame 13 is also provided in the support base and is driven via a transmission device.

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 glue amount uniform. When using a hot melt adhesive, it is necessary to provide a heating device in the glue tank. The entire gluing unit may be made to run on the rail 27 by a traveling device below the unit, or a stack of paper bound with the gluing unit fixed may move on the gluing 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 composed 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 increased, the adhesive force of the paste is increased and the strength is increased. It is desirable that the strength of the return form or the like, which is one object of the present invention, is not increased so much because the form is peeled off 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.

FIG. 5 is a flowchart for explaining the operation of the paper alignment mechanism. In S1, the paper is placed on the supply conveyor. Although the supply conveyor is not shown in FIG. 1, the paper is usually placed on the paper alignment mechanism by the supply conveyor. At this time, it is determined whether or not the bookbinding unit is processing (S2). If the processing is being performed, the conveyor stops and waits. If not, the conveyor is started (S3). After the paper is placed, the lower surface plate 10C is inclined with the point C as the lowest point, stops at a predetermined position, and then starts vibrating (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 10C stops the vibration (S
6). At the same time, the holding plate 10D descends to clamp the paper (S7).

The side plate 10B moves behind the lower plate 10C to expose the side of the sheet (S8). The entire paper aligning mechanism is rotated so that the surface on which the side plate 10B was located becomes the lowermost surface, and the lower plate 10C and the holding plate 10D are erected (S
9). The gluing unit moves along the lower surface of the exposed paper and glues the paper (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.
B returns to the original position (S12), and lower surface plate 10C returns to the original position (S13). When the holding plate 10D is opened (S
14) The bookbinding apparatus returns to the initial state.

[0016]

As described above in detail, according to the bookbinding apparatus of the present invention, it is possible to align sheets of paper such as forms and to perform binding using the same apparatus to perform bookbinding. Efficient work can be performed with less space.
