Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a copy finishing method in which sheets of copied paper are automatically aligned on a staple tray, stapled by a stapler, and any wrinkles are discharged onto a paper output tray. 7 Regarding the device [Prior art] After copying, paper is ejected by binding with a stapler (near 1"-1"). A cartridge containing stacked sheets of board material is installed in the Sudef bra, and the sheets are fed out from the cartridge in order from the bottom side and cut to the width of the binding needle, and then cut into the opening. Fold into a letter shape,
There is a device that uses the needle t to bind sheets of paper.

[Problem to be solved by the invention]

However, in a copy finishing device that uses plate-shaped staples stored in the stapler as a cartridge, when the staples run out, it is difficult to replace them by reinstalling a new cartridge. Some staplers require several blank strokes before the first staple is ejected from the stapler.

Therefore, in such a copy finishing device, if binding is performed in the normal stable mode immediately after a new stable cartridge is installed in the stapler, the copy paper in the bottom section that is ejected first will be bound in binding I: This causes inconvenience because the book is published in a state where it is not properly prepared.

This invention was made in view of the problems mentioned in 2. When the stapler ran out of staples and new ones were added, the paper was not stapled at the first stage. to prevent it from being discharged. "aimed to.

[Failure to solve the problem]

In order to achieve the above object, the present invention includes a stable 1-+noy to be placed when binding copied copy sheets, a staple for binding the copy sheets of the stable tray J-, and a staple for binding the copy sheets after binding. In a copy finishing device equipped with a discharge means for discharging a stack of sheets to a paper output 1-1, when all the binding nails in the stapler are exhausted and replenished, the button is pressed a predetermined number of times in succession until the button is pressed. The stapler operation mode switching means is provided for operating the stapler in a blank mode and then returning it to a normal stable mode.

[For production]

According to the copy finishing device configured in this way, when the stapler runs out of staples and new staples are replenished, the operation of the Stabler blank firing mode is executed.
Before the copied copy sheets to be bound are sent to the stave 1-ray 11, the staples are blank-stamped a predetermined number of times in succession, and the newly added staples are ejected.
Thereafter, the normal stable mode is returned to, and the first copy sheet fed onto the stave is driven in with a staple by the staple, so that the first copy sheet to be bound is surely bound.

A timing pulley 41 and a tension pulley 47, which are integral with a gear 40, are engaged with the first timing belt 5 from the inside and outside, respectively.

A gear 43 integrated with the pulley 38 meshes with the gear 40, and a second timing belt 39 is stretched between the other pulley 68 and the timing pulley 35, so that the relay rollers 62 and 33 are synchronously rotated in forward and reverse directions. It rotates in both directions.

The relay rollers 32 and 53 rotate at the same circumferential speed in the opposite directions of arrows E and C in FIG. 6, so that the stack of sheets held between them can be conveyed in the same direction. The dimensions of each part of the transmission system are set, and reverse rotation drive is also possible in the opposite direction.

The relay roller 63 and pulley 38 are shown in FIG. are each rotatably supported by brackets 1-,
In the bracket, a shaft 45 supporting the pulley 38 is supported by the front and rear side plates 1 and 51 via bearings, and is swingable in the direction of arrow G in FIG. When a bundle of thick sheets is inserted into the frame, the relay roller 33 swings together with the bracket 1- in the direction of the arrow G1 about the shaft 45 as a fulcrum.

A driven roller 49 is in pressure contact with the lower part of the relay roller 32, and a switching pawl 51 is disposed close to it so as to be switchable between the position shown in solid line and the position shown in phantom line in FIG.
A pair of guide plates 52 are provided on the transport F flow side of the switching claw 51 by attaching them to the side plates 31.

This paper relay unit 1-10 has front and rear side plates 3

and a second position shown by a phantom line.

As shown in FIG. 2, in this copy finishing device, when a copied sheet P is fed into a horizontal conveyance path 2 in the main body 1 of the device, its width is moved by a plurality of pairs of conveyance rollers on the horizontal conveyance path 2. The paper I) is conveyed to the right, and the time from when the paper I) is detected by the sensor 15 to when it is detected by the sensor 16 is used to determine whether or not the paper I) has been normally conveyed within the conveyance path.

Then, the paper P is guided to the vertical conveyance path 5 by the deflection claw 4 in the rotational position shown by the solid line in FIG. 2, and advances to the T' conveyance roller pair 8. As shown in FIG. 3, the switching claw 5 is located at the position shown by the solid line, and the paper relay unit 10 is located at the first position shown, and the paper P is transported and relayed by the rotation of the transport roller pair 8 in the direction of the arrow. It is sent between rollers 32 and 33.

By the way, in this copy finishing device, when all the binding staples 44 in the stapler 20 shown in FIG.
A stapler operation mode switching means is provided which executes a blank mode in which the stapler 20 is continuously operated by Z (detailed description will be described later) and then returns to the normal stapling mode.

And, this stapler empty firing mode can be used with stapler 2
When all the staples 44 in 0 are gone, the stapler automatically shifts to the empty firing mode, and then automatically returns to the normal stibble mode.

The series of controls are all performed automatically by a control device 60 shown in FIG. That is, in this embodiment, the control device 60 functions as the above-mentioned stibbler operation mode switching means.

The control device 60 includes a central processing bag [(CPl, -r) having various judgment and processing functions, and a program storing fixed data and programs necessary for executing the stapler empty firing mode and the normal stapler mode. It is a microcomputer consisting of a ROM that is a memory, a RAM that is a data memory that stores processing buttons, and an input/output circuit (Ilo), and is also equipped with drivers to drive a counter and various drive systems. .

This control device 60 inputs an on/off signal from the main switch, as well as from a staple detection sensor 48 that detects the presence or absence of a staple 44 stored in the stapler 20 and a sensor 17 that detects paper on the staple tray 7. Input the detection signals respectively, and then input the detection signals from the various sensors of this copy finishing device. 6.

Further, signals for driving each drive unit of the paper feed system in this copy finishing device are sent to the staple tray 7.
It outputs signals for driving each drive system related to paper alignment, etc. attached to the machine, and signals for driving various rollers, etc. for the paper ejection system, and also connects this copy finishing device. A signal for feeding copy paper to a paper feeding system of a copying machine (not shown) is output.

If the needle breakage is not detected, the process proceeds to step 15, and normal stibble mode processing is executed to prevent the stapler 20 from firing blankly, but if the needle breakage is detected, the process proceeds to step 2.

In step 2, a display signal to inform the operator of the needle cutter 7 is outputted to the display unit 61 (outputted after being delayed in accordance with the actual needle breakage timing in consideration of the position of the needle detection sensor 48), and is output there. ``Stibble needle replenishment'' is displayed, and in the next step 3, the presence or absence of needle breakage 5 is detected again, and if the needle has not been replenished yet, wait, and when it is replenished, the needle detection sensor 48 detects the needle breakage. If it is no longer present (determination of No), the process proceeds to step 4, and the display of "stable needle replenishment" displayed on the display section 61 in step 2 is reset.

Next, in step 5, the moving device 22 and the forward/backward moving devices 42A and 42B are driven to a blank-feeding mode position where the stapler 20 is positioned on the paper P, and the stapler 2OA is
When the staple runs out on either side, move the Stibler 2OA to the position not shown by the solid line in Fig. , c) At the -1 position, the needle 44 is made ready for driving.

Then, in step 6, the number 48 for feeding dummy paper is output to the drive unit of the paper feed system of the copying machine connected to this copy finishing device, and the number 48 is output to the paper feed force sensor 1 of the copying machine. A blank dummy paper (ordinary transfer paper) on which no image has been transferred is fed toward the staple tray 7.

Please note that this dummy paper is only to be used for adjusting the stapler's blank stitching (the staples are driven in at the final stage of blank stitching), and should be disposed of after the blank stitching adjustment. Therefore, normally blank paper is used as described above, but paper on which the image has been transferred may also be used. Further, the number of sheets is appropriately determined depending on the stiffness of the binding bolt 44 used.

Then, in step 7, the dummy paper is stored in the staple tray 7 (abbreviated as tray 7 in FIG. 7) -h-.
, it is determined whether or not the sheets are aligned at the predetermined alignment position (the position where the paper P is located), based on the signal from the sensor 17 (FIG. 3). Outputs an operating signal to the drive and drives it.

Next, in step 9, it is determined whether or not the number of times the stapler 20 is driven has reached a predetermined number N1, which will be described later. The operation continues, and when the number of operations reaches N1, the process proceeds to step 10.

Therefore, the forward/backward moving device 42A (because the explanation is now assuming that the stapler is running out on the stapler 2OA side) is driven,
As shown in FIG. 1, the stapler 20A is inserted a predetermined amount 1. Move in the direction indicated by the arrow J and stop at the position shown by the imaginary line.

In addition, this predetermined amount is determined by the stapler 2OA.
Assuming that 4 is stamped on the dummy paper (P),
Next, type (all 4 digits are the first number of -r).

Set the spacing so that the needle can be struck at 4T44 without interfering with the needle.

Then, the next step 11'r'', Sudeipura 2[]l
(After step 12a, replenish the forceps 44 of the stapler 20.) Determine whether or not the number of barrels has reached N2, and if the number of barrels has not been reached, Returning to Step]-0, the stapler 20A is further moved from the position indicated by the imaginary line in FIG. Then, the paper ejection drive system is driven to eject the dummy paper on the staple tray 7 onto the paper ejection l/reiro.

Thereafter, in step 14, the moving device 22 and the forward and backward moving devices 42A and 42B are driven to move the stapler 20 to the specified binding position as necessary.

In step 15, the normal stable mode processing subroutine is executed, and the sheets that are copied and sent sequentially onto the stave 1-leaf are aligned, stapled with the stapler 20, and ejected onto the [paper]-Reiro. .

Once means that when the stapler 20 cuts the staples, the stapler 44 is refilled, and then the stapler 20 is moved to the position shown by the solid line in FIG. This is the number of times the stapler continues to perform the stapler operation (at a position symmetrical to the paper), and it varies depending on the type of stapler used and the cartridge that houses the staples.

The N1 number of times is calculated by assuming that the designed number of blank strokes until the first staple comes out after refilling the stapler is N (in the case of a design in which the first staple comes out at rN + IJ strokes) in the combination of stapler and cartridge used. It is predetermined as N1≦N.

Further, N2 times in step 12 is the number of times of 1-1 barrel driving after replenishing the needle 44 until the blank driving mode is ended, and there is a relationship of N2≧N.

In addition, in this embodiment, the reason why the dummy paper is used during the blank firing mode is that if it is not used, the needle will be fired at the final stage of the blank firing mode (only when N2=N). This is to prevent the stapler from becoming inoperable if the knife (the sword does not come out) falls and gets stuck inside the stapler.

Therefore, in this embodiment, if NZ is set to be larger than N (Nz>N), the stitching bolt 44 is driven into the dummy paper by the stapler 20 in the final stage of the blank printing mode. This is more preferable because it shifts to the stapling mode of the buoy.

That is, when NZ = N, the stapler 20
Immediately after performing the stapling operation for the designed number of blank stapling operations, there is no margin at all before the staple mode shifts to the normal stapling mode and the staples are ejected. However, if N2>N is set like this, there is a margin for the number of strokes, so the staple 44 is reliably driven from the first stroke after switching to the normal staple mode. You can bind copy paper using the

〔Effect of the invention〕

As explained above, according to the present invention, when there are no staples left in the stapler and new staples are refilled, the blank stapler mode is activated, and the copy sheets to be stapled become stable. Before being sent to Tray 2, the stapler is used to make the newly added staples ready for firing.

The stapler can reliably staple the first copy paper fed onto the stapler 1 in the normal stable mode after the blank printing mode, and prevents unstitched copy paper from being ejected immediately after replenishing the staples. It disappears.
