Abstract

PURPOSE:To simplify automation for bookbinding by holding a copy group stacked on a table in between from the upside under pressure, and in this state, binding it after applying an adhesive to a sizing edge as rotating the table around a shaft, then further rotating it to release the pressure and dropping it on a tray from the table. CONSTITUTION:A copy group is stacked as copies discharged on a table are arranged right, by a rear end guide 21 and a tip end guide 15 installed in a table 4 supported by a shaft 3. Then, the copy group is pressed by rotation of an upper guide plate 10. In this state, the table 4 is rotated in an A direction around the shaft 3 along the circular tip end guide 15, and it is glued by a sizing roller 17 when a sizing edge has come to a B position. After that, the table is reversed, and thereby a table rear end unifier is retracted at a C position, while a pressing means 10a is released, so that the copy group is discharged onto a tray 22 from the table rear end.

Description

DETAILED DESCRIPTION OF THE INVENTION i11 The present invention relates to a bookbinding device that binds a group of copies made by a copying machine by gluing.

Most of the copies made with the Census 1 copying machine are bound with a stapler, and there are currently not many cases where they are bound with glue.

However, adhesive bookbinding has advantages such as the binding part is easy to open and the binding metal does not damage hands, desks, etc., and there is a demand for an apparatus that can easily perform adhesive binding.

By the way, the conventional glue binding device is, for example,
- As disclosed in Japanese Utility Model Publication No. 1'29810 and Japanese Utility Model Application Publication No. 51-129811, a stack of duplicated copies or printed materials is placed in a predetermined place and clamped with a clamp member. In many cases, bookbinding is performed by reciprocating the paper along a predetermined moving path, during which glue is applied to the back of the paper by a glue application roller, and the paper is discharged. The flow was poor, the device was bulky, and it had poor operability and was unsuitable for use as a peripheral device for copying machines and printing machines.

1-E The present invention, in view of the above-mentioned circumstances of conventional glue-type bookbinding devices, provides a glue-type bookbinding device that can automatically bind books with a simple configuration and is suitable as a peripheral device for copying machines and printing machines. The purpose is to

1" [The bookbinding device according to the present invention achieves the above objectives,
A means for receiving copies ejected from a copying machine main body; a copy stacking means for stacking the copies received by the receiving means on a table with one end thereof aligned with a stack reference; and a copy stacking means for stacking the copies stacked on the table. a pressing means for pressing from above and holding the copy group between the table; a mechanism for rotating the −F table around one axis with the copy group being held between the table and the pressing means; It is provided in the passage of the gluing edges of the group of copies rotated by the rotating S structure, and it also rotates the table (which sandwiched the means for applying glue to the gluing edges of the group of copies and the group of copies that have been bound with glue applied) and further rotates the table. and a tray for receiving a group of bound copies that fall off the table by releasing the pressing means.

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 1, the bookbinding apparatus 40 of this embodiment is connected to and installed in the copying machine main body 30 and is used as a peripheral device of the copying machine 30.

As shown in FIG. 2, the paper ejection roller 18 of the copying machine main body 30
A receiving roller 19 is provided at a position to receive the copy sent out from the copying machine, and is rotated to the copy center. The table 4 is stopped at a position A where it receives the copy released from the receiving roller 19. As shown in detail in FIG. 5, the table 4 is fixed to a shaft 3 rotatably supported on the side plate 1 via a bearing 2, and is driven by a gear 8. By rotating the shaft 3 via the shaft 5, the shaft 3 rotates integrally with the shaft 3.

As shown in FIGS. 3 and 4, protrusions 4a are provided on both sides of the table 4 toward the upper part of the position supported by the shaft 3. Axis 9
An upper guide plate 10 is integrally attached to the protrusion 4a.
The shaft 9 and the upper guide plate 10 are rotated together by a motor 13 fixed to the table 4 through a gear train 1.2.11, so that the angle with respect to the table 4 can be changed.

In FIGS. 2 and 3, the right end of the table 4 is brought into contact with the ejection end of the copies ejected onto the table (the rear end when aligning the copies), and returned in the opposite direction until it hits the leading edge guide 15. A copy trailing edge alignment 21 is provided to align the copies. As shown in FIG. 3, the copy trailing edge alignment 21 is displaced between the position shown by the solid line and the position shown by the broken line by an eccentric cam rotated by the motor 14, and is discharged from the receiving roller 19 at the position shown by the solid line. By accepting the copy and displacing the trailing edge alignment 21 to the position shown by the broken line, the leading edge of the paper is pressed against the leading edge guide 15 to align the paper.

The guide surface of the tip guide 15 is composed of a circular arc surface centered on the shaft 3, and the copy group whose tip is placed on the table 4 at the solid line position and aligned and tititized is rotated by the motor 13. The tip of the copy bundle is pressed by the upper guide plate 10, and is held between the table 4 and the holding part 180a at the tip of the upper guide plate 10. When the shaft 3 and table 4 are rotated counterclockwise by the motor 7, the copy bundle is The leading end surface moves along the guide surface of the leading end guide 15, and when the table 4 reaches the position B shown by the broken line, the copy group held between the table 4 and the holding part 10a at the leading end of the upper guide plate 10 is released. The tip escapes from the range of the tip guide 15.

A glue roller 17 is provided at that position so as to be in contact with the extended surface of the tip guide 15, and is wetted with glue in the glue tank 16.

A tray 22 is provided at a position further behind the gluing roller 17.

A population sensor is provided immediately upstream of the receiving roller 19, and the motor 14 is operated in a timely manner based on a copy detection signal from the population sensor.

The operation of this device will be explained below.

The copy sent out by the paper ejection roller 18 of the copying machine is
It is received by the receiving roller 19 of the bookbinding device and discharged onto the table 4 at the position A shown by the solid line in FIG. When the leading edge of the copy enters the binding device, the population sensor 20
After a predetermined period of time has elapsed after the detection, the motor 14 starts operating, and the rear end presser 21 moves from the position shown by the solid line to the position shown by the broken line in FIG. 3, and then returns to the position shown by the solid line. As a result of this operation, the copy ejected onto the table 14 is pushed back to the left in the figure, and the rear end at the time of ejection hits the leading edge guide 15 first. 1 copy population sensor 20
Each time the rear end alignment 21 is detected, the rear edge alignment 21 makes one reciprocation and the copies are aligned at the position where they collide with the leading edge guide 15. When a predetermined number of copies to be bound into one book are sent, a command to finish supplying the original is issued from the original supply unit, and the ejection of the final copy is detected by the population sensor 20, the motor 14 rotates half a rotation. Then, the rear edge alignment 21 presses the final copy against the leading edge guide 15, and stops at that position with all the copies on the table 4 pressed against the leading edge guide 15.

Next, the motor 13 rotates, and the upper guide plate 10 is lowered via the gear train 12.degree. 11 to the position shown by the broken line in FIG.
The upper and lower surfaces are held between the presser foot 10a and the table 4, and the front and back are held between the front end guide 15 and the rear end aligner 21 to ensure alignment.

Next, the motor 7 shown in FIG. 5 rotates, and the gear trains 8, 5
The table 4 guides the tip of the copy group through the tip guide 15.
Rotate counterclockwise while sliding the copy group into position B shown by the broken line in Figure 2, and the tip of the copy group will align with the tip guide 1
5 and passes through while contacting the gluing roller 17, and glue is applied to the leading end surface of the copy group. The amount of glue applied can be adjusted by changing the rotation speed of the gluing roller, by making the gluing roller 17 follow the group of copies, or by rotating it back and forth.

After passing through the glue application position, the table 4 is further rotated and when it reaches the position C shown by the broken line in FIG. 1, the upper guide plate 1
By rotating the presser foot 10a at the tip of the presser 0 in a direction away from the group of copies on the table 4, the group of glued and bound copies is released onto the tray 22 by its own weight.

In this case, the copy group is placed on the tray 2 with the glued end first.
Since it falls upward and the glued end hits the stopper part 22a at the tip of the tray 22, depending on the type of glue, the glue may hit the stopper part 22a in a state that is not yet dry. If you want to avoid this, make sure that the trailing edge alignment 21 can be retracted from the top surface of the table 4, and after completing gluing the copy group at position B, rotate the table 4 clockwise and When the end is at position C, rear edge alignment 21
is retracted from the surface of the table 4 and the upper guide plate 1
By releasing the presser foot 10a, it is also possible to release the group of copies onto the tray 22 from the two opposite sides of the glued end.

In addition, if you want to discharge the stacked copies on the table 4 onto the paper output tray with the top side up, the positions of the gluing tank 16 and gluing roller 17 should be changed to the second position, as shown in FIG.
It is only necessary to arrange the paper discharging tray 22 to the upper left than the embodiment shown in the figure, and to eject the paper toward the lower left immediately after that.

1.1 As described above, according to the present invention, it is possible to bind a group of copies by gluing with a simple configuration, and by attaching it to a copying machine, it can be used as a simple paper output tray depending on the mode of use.
It can also be used as a bookbinding device.

In addition, since glue binding can be performed automatically, the copying productivity can be increased as a post-copying processing device of a copying machine.

Furthermore, it is more compact than conventional glue binding devices, making it suitable as an accessory to a copying machine.
