DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit paper obtained from printed continuous paper or page unit paper, which is sequentially transferred and collated in a buffer unit for each collation unit, and then bound with staples or the like. The present invention relates to a bookbinding apparatus for binding a booklet. For example, the continuous paper is provided with a margin cutting perforation extending in the longitudinal direction along the vicinity of both sides and a plurality of cutting perforations extending in the width direction at regular intervals, and is divided by each perforation. The item columns are printed in advance in the section serving as the unit paper, and predetermined items are individually printed in each item column by a page printer (not shown). In the continuous paper, one unit paper serving as a cover and a plurality of unit papers to be collated with the unit paper are sequentially connected so as to form one collation unit to be collated. Further, the page unit paper is formed so that one page is divided into a plurality of pages to form one collation unit.

[0002]

2. Description of the Related Art A conventional bookbinding apparatus includes, for example, a supply section which folds and folds a continuous sheet in a bellows shape at each perforation extending in the width direction and arranges the continuous sheet, sequentially pulls out from the upper portion, and supplies each processing section. After cutting the margins of the continuous paper that has been pulled out at the perforation for cutting, the continuous paper after cutting is removed at the cutting perforation to form the unit paper, and the unit paper is sequentially transported, reversed, and collated for each unit. Then, there is a binding unit that binds with staples or the like, and a stacker unit that takes out a binding booklet and stores it in a set order.

[0003]

In the above conventional example, the reversing mechanism is complicated and large, so that not only the unit must be large and the installation space must be wide, but also the bookbinding function is only provided. Therefore, there is an inconvenience that a dedicated machine is used and processing that only cuts the paper cannot be performed. The present invention has been made in view of this inconvenience, and it is an object of the present invention to provide a bookbinding apparatus capable of reducing the size of a unit and using only a continuous paper cutting function in addition to a bookbinding function.

And a stitcher 45 for binding the united sheets 2a and 2b.

As shown in FIG. 1, the stacker section 8 comprises a conveyor 46 and an inclined stopper 47 provided at the outer end (right end in the drawing) of the conveyor 44. The booklet discharged from the binding section 7 to the conveyor 46 is transferred from the left end of the drawing to the right end of the conveyor 46,
The booklet is stocked by repeating the operation of standing obliquely with the inclined stopper 47 leaning on the slope, and standing with the following booklet inclined with the slope of the booklet.

As shown in FIG. 5, the bookbinding apparatus 1 comprises:
The operation of each unit is configured to be controlled by the control unit 48.
In the figure, reference numeral 49 denotes an operation unit having various operation keys arranged on a keyboard (not shown), reference numeral 50 denotes a storage unit for storing the number of finished booklets and the like, and reference numeral 51 denotes the bookbinding apparatus 1.
And a display unit for displaying the driving state of the printer and the number of finished booklets.

Next, the operation of the bookbinding apparatus 1 in the booklet mode will be described with reference to FIG. The operator operates the keys of the operation unit 49 to input settings such as the number of booklets to be set, mode settings (in this case, booklet mode), etc., while displacing the slitter 4 obliquely upward by rotating the displacement member 24. When the start key is turned on by inputting so as not to touch the page unit paper 2, the supply unit 3, the cutting unit 5, the buffer unit 6 and the binding unit 7 are driven (step 101), and the page unit paper 2 is The sheet is sent to the cutting section 5 and cut, and the unit sheet 2a serving as the front cover of the booklet and the unit sheet 2b serving as the second and subsequent pages are transported in the order in which they are successively provided and superimposed in the buffer section 6 so as to be sequentially fed downward. It is collated. At this time, after the unit sheets 2a and 2b of one collation unit are sent out from the supply unit 3, the unit sheet 2a to be the next cover divided at the advancing end of the page unit sheet 2 is located at the position just before the cutting unit 5. When it reaches, the first
The mark reading unit 15 detects the cover mark 14 (step 102), and stops the supply of the page unit paper 2 by the supply unit 3 while the cutting unit 5, the buffer unit 6, and the binding unit 7 are driven (step 102). 103).

The united sheets 2a and 2b are bound by the binding unit 7 and sent out as a booklet, and the cover mark 14 attached to the uppermost unit sheet 2a is marked with a second mark.
Is detected by the mark reading unit 16 (step 104).
Then, the supply unit 3 is driven again to supply a new page unit sheet 2 to the cutting unit 5, while the booklet is discharged to the stacker unit 8 (step 105). In the stacker section 8, a booklet is transferred from the left end to the right end of the conveyor 46 in FIG. The booklet is stocked by repeating the action of standing.

When a booklet is prepared in this way and the stack amount has not reached the set number, the process returns to step 101 to return to the supply unit 3, the cutting unit 5, the buffer unit 6, and the binding unit 7.
Is driven, and the above operation is repeated. When the number of booklets reaches the set number, a stop signal is output (step 1).
06), the bookbinding apparatus 1 stops. On the other hand, the set number of booklets leaning against the inclination stopper 47 are transported by a transport vehicle or the like, and when a further booklet is to be prepared, the start key is turned on and the same operation as described above is continued.

When the operator switches the setting mode to the cutting mode, inputs the setting mode, and turns on the start key, the cylinder 37 retracts, the cylinder 39 protrudes, and pushes the arm 33 clockwise in FIG. Since the stopper 28 is lowered, the unit papers 2a and 2b pass through the buffer unit 6. This passed unit paper 2a,
2b is not bound by the binding section 7 and is also passed through the binding section 7 and transferred to the stacker section 8 without forming a booklet.

The present invention is not limited to the above-described embodiment. For example, the present invention is applicable not only to processing a page unit sheet in which a plurality of unit sheets forming one unit are connected, but also to processing of a continuous sheet. May be. When this continuous paper is used, a tractor device is used as the supply unit 3, and the marginal portion is cut and removed by the slitter 4.

[0025]

As described above, according to the first aspect of the present invention, a continuous sheet of unit paper constituting one unit to be collated or a plurality of unit sheets constituting one unit to be collated are connected. There is an effect that the page unit sheets can be collated and bound in the order and the number of sheets according to the setting.

According to a second aspect of the present invention, a continuous sheet of unit paper forming one collation unit or a page unit paper in which a plurality of unit papers forming one collation unit are connected is set as set. In addition to being able to collate and bind in order and number of sheets, it is possible to take out the booklet and accurately stock it in collation order, and use it as a cutting device because it can be switched between booklet mode and cutting mode. It has the effect of being able to do so.

Further, the present invention described in claim 3 provides the effects of the invention described in claim 1 or claim 2,
When one unit of continuous paper or page unit paper is sent out from the supply unit, the supply is temporarily stopped, and the preceding one unit is turned into a booklet, and then re-supplied. There is an effect that collating and binding can be performed more accurately in order.
