Description

Detailed Description of the Invention (Technical Field) The present invention is based on a patent application filed in the same application as the applicant.
The present invention relates to a binding device in a bookbinding machine described in No. 54-146683.

(Prior art) The bookbinding machine of the prior invention carries out each process in one process, from sequentially copying copies made by a copying machine to folding them in half, arranging them, binding them, sealing them (perforating them), stamping them, and discharging them. It is characterized by being carried out continuously. The binding process is performed by passing the stapler needle through one side edge of the sheets aligned by an alignment device, but if the sheets are not aligned properly, binding defects may occur. do. The alignment device of the bookbinding machine in the prior invention sometimes caused misalignment when the number of laminated sheets increased, so it was subsequently improved. This improved alignment device uses a first alignment lever to press the leading edge of the sheet so that the trailing edge of the sheet abuts the first stopper, and also pushes one side edge of the sheet into the second alignment lever. It is characterized in that the sheets are aligned by pressing the other side end of the sheet into contact with the second stopper using an alignment lever. In the case of such an alignment device, the second alignment lever at the sheet side end is normally retracted to a position away from the sheet side edge so as not to interfere with the sheets being carried into the alignment device. The plunger is energized to swing, push the sheet side end, and then retreat again. At this time, if the number of laminated sheets is small,
When the second alignment lever returns, the seat may bounce due to the force of the seat's own hips, resulting in uneven edges of the seat.

(Purpose) The object of the present invention is to provide a bookbinding machine having a device for aligning sheets by pressing an alignment lever such that the binding process can be performed with the sheets aligned again by pressing the alignment lever. An object of the present invention is to provide a binding device configured as follows.

(Structure) The binding device according to the present invention operates, in the bookbinding machine, the second alignment lever to a position where it presses the side edge of the sheet based on a binding signal that activates the stapler in the binding process;
It is characterized by comprising alignment lever control means for returning the second alignment lever to an initial position spaced apart from the side edge of the sheet based on a binding operation completion signal from a switch that is turned on and off in conjunction with the operation of the stapler. shall be.

Hereinafter, the present invention will be described with reference to the attached drawings.

FIG. 1 is an external view showing an example of the bookbinding machine described above. This bookbinding machine is equipped with a folding device, an alignment device, a binding and sealing device, and a stamping device that fold, align, bind, seal, and stamp sheets, and this bookbinding machine is used in combination with a copying machine. By doing so, it is possible to automatically copy and bind certified copies, extracts, and other documents.

1 and 2, reference numeral X indicates a copying machine, Y indicates a bookbinding machine, 100 indicates a folding device, 200 indicates a binding and sealing device, and 300 indicates a stamping device, respectively.

Hereinafter, taking the case of creating a certified copy (or an extract) as an example, the creation process will be described in order, and the structure, operation, function, etc. of the bookbinding machine Y will be briefly explained.

First, the original copy is copied by copying machine X.

The original certified copy is shown in Figures 1 and 2.
After the information on the original is scanned by the original feeding device 400 of the copying machine X, the original is ejected onto the original ejection tray 401. Information on the original document is copied onto a copy sheet (hereinafter simply referred to as a sheet) S via an information recording medium (photosensitive drum and its peripheral devices) 402 . Sheet S on which original information is copied
is conveyed toward the bookbinding machine Y through the sheet discharge port 403 of the copying machine X.

As shown in FIG. 3, the sheet S discharged from the sheet discharge port 403 of the copying machine The sheet is conveyed through the sheet to a sheet carry-in roller 502 disposed on the side of the bookbinding machine Y.

The sheet S carried into the bookbinding machine Y is conveyed by a carry-in roller 502, and as shown in FIG. , proceed toward the first conveyance roller 504. The sheet S conveyed on the first flow plate 503 by the carry-in roller 502 is placed at the rear end (the left end in FIG. 4).
However, just before it leaves the carry-in roller 502, its leading end is conveyed by the first conveyor rollers 504 and further advances. The sheet S further conveyed on the first flow plate 503 by the first conveyance roller 504 is placed approximately at the center of the main body of the bookbinding machine, which is disposed in a direction approximately perpendicular to the first conveyance path A. When the tip of the sheet S comes into contact with the partition plate 506 located thereon, its progress is temporarily stopped on the first flow plate 503 (this stopping position of the sheet S will be hereinafter referred to as the first position of the sheet). .

Next, the sheet S is conveyed on the first flow plate 503 through a second conveyance path B (see FIG. 2) that is substantially perpendicular to the first sheet conveyance path A and along the partition plate 506. . This second conveyance path B
A sheet introducing section 10 of the folding device 100 is downstream of the folding device 100.
0a corresponds (see Figure 5).

The sheet S folded in half by the folding device 100 passes over the second flow plate 511 to the third conveyance path C.
It is conveyed toward by the second conveyance roller 512 having a ball roller structure.

Sheet S conveyed onto this second sink plate 511
is the side edge or tip (fifth
(on the left side in the figure) contacts the sheet stopper 5131, which is disposed in a direction substantially perpendicular to the third conveyance path C of the sheet from the folding device 100 to the second flow plate 511. (This stopping position of the seat S is hereinafter referred to as the second seat position). At the same time as the sheet S reaches the second position, the second transport roller 512
The sheet is guided by the sheet stopper 5131, and is guided by the sheet stopper 5131, and is mounted on another support shaft that rotates substantially perpendicularly to the support shaft. It is transported along a fourth transport path D that is substantially orthogonal to C (see FIGS. 6 and 7).

The sheet S whose sheet conveyance direction has been changed at the above-mentioned second position is transported to a sheet aligning and binding marking section (hereinafter simply referred to as sheet sheet) provided adjacent to the second flow plate 511 on the fourth conveying path D side of the second position. 514 (referred to as a binding section) (see FIG. 9). The sheets S conveyed to the sheet binding section 514 are temporarily stocked on the sheet laminate plate 515.
The sheet laminate 515 is stocked on the sheet laminate 515 rather than on the sheet guide surface of the second flow plate 511. The stacking surface of the sheet is located at a lower position corresponding to the maximum amount of stacked sheets. In addition, this sheet binding section 5
14, the sheet feeding section 5 corresponds to the sheet feeding side of the second sink plate 511 (right side in FIG. 6).
14a, the leading edge Sa of the sheet S carried into the sheet binding section 514 is bent toward the above-mentioned sheet stacking surface, and the height of the upper surface of the sheet stacked on the sheet stacking plate 515 is A sheet guide member 516 is provided to face the sheet guide surface at a position lower than the height of the sheet guide surface of the second flow plate 511.

By the way, this sheet is placed on top of the sheet S carried into the sheet binding section 514 in the same position as it is.
In other words, if the next sheet is stacked on top of the next sheet in the same posture as when it was delivered, there is a high possibility that these sheets will be misaligned with each other. Therefore,
If sheets in an irregular state are bound and sealed as they are with the binding and sealing device 200, not only will the quality of the certified copies be poor, but there is also a risk of sheet jamming during the process of transporting the sheets to the next process. . Therefore, in this sheet binding section 514,
It becomes necessary to align the stacked sheets with each other. This alignment of the sheets is carried out by a first alignment device 600 (see FIG. 10) for aligning the leading edges Sa of the sheets traveling along the fourth conveyance path D.
and a second aligning device 700 (11th (see figure).

The first alignment device 600, as shown in FIG.
An alignment roller 601 disposed horizontally and substantially orthogonal to the fourth carrying path D, and a pressing member disposed substantially horizontally that swings toward and away from the alignment roller 601 from below. 602, an L-shaped first alignment lever 603 disposed substantially vertically that swings opposite the tip Sa of the sheet S, and a first plunger 604 for swinging these.
It has a first stopper 605 vertically disposed on the opposite side thereof. The pressing member 602 is formed of a leaf spring whose tip end is inclined downward, and its horizontal part is located slightly above the sheet laminated plate 515, and the opening 6 provided in the vertical part of the alignment lever 603
03a, and its base is fixed to a support member 607 that is pivotally supported by a shaft 606. The horizontal base of the alignment lever 603 is also fixed to the support member 607, and both the pressing member 602 and the alignment lever 603 extend outside the side plate 518 through an opening 518a provided in the side plate 518. A plunger 60 fixed to the side plate 518 is attached to the end of the support member 607 on the side plate 518 side.
The tips of the four actuating pieces 604a are connected,
Due to the on/off operation of the plunger 604, the support member 607 swings around the shaft 606, and along with this, the pressing member 602 and the alignment lever 60
3 is an opening 51 provided in the sheet laminate 515
It is designed to swing through 5a. In this embodiment, the side wall of the sheet laminate 515 also serves as the first stopper 605 . The alignment lever 603 is held approximately vertically in the normal state, that is, in the de-energized state of the plunger 604, and the stopper 605 is held from the inside thereof at that time.
The distance to the inside of the sheet almost matches the lengthwise dimension of the sheet S used during bookbinding.

As shown in FIG. 11, the second alignment device 700 is disposed in the direction of the fifth conveyance path E, which is perpendicular to the fourth conveyance path D (see FIG. 2), and is approximately aligned with the sheet laminate 515. vertically and the opening 515b
a second alignment lever 701 disposed through the
Holding this second alignment lever 701, the support shaft 70
a support member 703 that is swingable about 2, and an actuating piece 7 connected to the tip of this support member 703;
04a, and a second stopper 705 disposed substantially perpendicularly on the fifth conveyance path E side on the opposite side thereof. In a normal state, that is, when the second plunger 704 is in a de-energized state, the second alignment lever 701 is inclined outward as shown by the broken line, and the second alignment lever 701 is tilted outward as shown by the broken line.
When 04 is excited, it is held in a substantially vertical state as shown by the solid line. The distance between the inner sides of the second alignment lever 701 and the second stopper 705 in the excited state almost matches the width direction dimension of the sheet S used during bookbinding.

Sheet S carried onto sheet laminate plate 515
are aligned in the following manner by alignment devices 600 and 700 configured as described above.
First, along the fourth conveyance path D, the sheet laminate 51
The rear end Sb of the sheet S carried in on the third
It is detected by the sensor SW ₃ , and the signal serves as a trigger to excite the first plunger 604. At this time, the leading end Sa of the sheet S is positioned below the alignment roller 601. When the first plunger 604 is energized, as shown in FIG.
The alignment lever 603 rotates a certain amount in the clockwise direction, and the tip of the pressing member 602 presses the tip Sa of the sheet S against the circumferential surface of the alignment roller 601.
Since the alignment roller 601 is rotating in the D direction at the point of contact with the sheet S, the sheet advances in the D direction and stops when it hits the first alignment lever 603. The excitation time for the first plunger 604 is determined so that the leading end of the sheet S contacts the first alignment lever 603 until it is connected. When the leading edge of the sheet hits the first alignment lever 603, the excitation to the first plunger 604 is released, and the pressing member 602 and the first alignment lever 603 rotate in the opposite direction again, thereby causing the leading edge of the sheet S to align with the first alignment lever 603. It is pushed in the direction opposite to the D direction by the alignment lever 603 and stops when it hits the first stopper 605 on the opposite side. Using this de-energization of the first plunger 604 as a trigger, the second plunger 7
04 is excited. When the second plunger 704 is energized, the second alignment lever 701 rotates about the shaft 702 and becomes vertical, as shown in FIG.
press against. In this way, the leading and side edges of the sheet are positioned (hereinafter, this position of the sheet S will be referred to as the third position of the sheet). The energization time for the first and second plungers is short and the positioning action takes place almost instantaneously. When the second plunger 704 is de-energized, the second alignment lever 701 returns to the position shown by the broken line and retreats so as not to interfere with the next sheet entering the sheet stack 515.

While such alignment work is being carried out, a second original sheet is copied by the copying machine The sheets are aligned and stacked correctly on top of the first sheet. In this way, a predetermined number of sheets (according to the number of originals or by setting the copy repeat counter of copy machine X) are automatically copied to bookbinding machine Y. The binding and sealing device 200 operates while the sheets (to be carried in) are sequentially arranged in the third position (see FIG. 12).

The illustrated binding and sealing device 200 includes two staplers 201 and one punch 202 (see FIG. 9).
The sheet laminated at the third position (1
It has the function of binding and perforating seals at the same time. Each stapler 201 and punch 202 is connected to a crank mechanism 20
3 and a swinging rod 20 that swings via a connecting rod 204.
They are each driven by the oscillation of 5. Each stapler 201 is detachably mounted on the upper surface of the sheet laminate 515 on the opposite side facing the second sheet stopper 705 . Also,
The punch 202 is disposed below the swinging rod 205, and each of its perforating shafts is located inside each stapler 201, respectively. Each of the stapler 201 and punch 202 is arranged such that its binding portion and punching portion are located above the side edges of the sheets stacked at the third position.
are arranged respectively. This binding/sealing device 200 uses the exposure signal that is output from the copying machine However, each time the operation of the buffer memory and the second plunger 704 of the bookbinding machine Y is completed, data is retrieved from the buffer memory, and when the retrieved signal includes a binding signal,
Alternatively, when the scheduled signal includes a stamping command signal, or after all the scheduled originals have been exposed and the second plunger 704 of the bookbinding machine Y has been activated to align the final copies, the operator switches the switch. It is activated when a seal stamping command is issued by pressing , and in other cases, for example, the sheet jams in the middle of each of the above-mentioned conveyance paths, thereby causing the second plunger 704
does not work, or if the copy repeat is not completed and sheets are being copied intermittently,
Otherwise, if the seal sealing command has not been issued, the respective operations will not be performed. Therefore, defective binding is reliably prevented, and by not issuing a signature stamping command, it is also possible to perform only folding on the sheet.

In the illustrated bookbinding machine, operation of the binding and sealing devices is stopped by pressing a special seal release button 411 (see FIG. 1). When you press the contract release button, the third plunger 519 (9th
(see figure) remains off, and its actuating piece 519
a and the spring clutch 520 remain disengaged, and the gear G ₃ freely rotates with respect to the shaft G _{3 a} . Therefore, from the main shaft G _1a to the gear G ₂
The power transmitted through is not transmitted to shaft _3a ,
Therefore, the crank mechanism 203 does not operate, and binding and sealing operations are not performed.

In this bookbinding machine, when a binding signal is issued, the second plunger 7 of the second aligning device 700 is
04 is excited. This is a sheet laminate 515
When the number of sheets stacked above is small, the second plunger 704 is energized during the alignment operation and the second alignment lever 701 pushes the side edge of the sheet S, and the excitation is released and the alignment lever 701 returns to its original position. This is because when returning to the position, the seat S may bounce back due to the force of the user's own hips and may not be aligned. It is not preferable to bind and seal in such an uneven state, so when binding and sealing, the second plunger 704 is energized again.
The binding and sealing is performed while the side edges of the sheets S are held down by the second alignment lever 701. At this time, the excitation of the second plunger 704 is canceled by the switch 207 (the 12th
(see figure).

This switch 207 is operated by the cam plate 206 that rotates in conjunction with the crank mechanism 203 when the binding and sealing device 200 operates normally and the binding and sealing of the sheets are completed.
When a binding (seal) operation completion signal is issued by the switch 207, this signal causes the stapler remaining amount counter of the stapler 201 to be decremented by one, and the fourth plunger 521 (see FIG. 14) is activated. The energized, bound and stamped sheets are conveyed on the fifth conveyance path E toward the next stamping section.

The fourth plunger 521 is attached to the side plate 518 (see FIG. 9) in the alignment device,

A notch provided at the other end of the second locking plate 525 has a pin 536 provided on the third locking plate 535.
is locked. The third locking plate 535 is arranged parallel to the second locking plate 525, is fixed to a shaft 537 that is the center of its swing, and is given a clockwise rotational habit by a spring 538. A piece 539 is also rotatably attached to the shaft 537.
7 is rotatably supported by the device side plate 518. One end of the piece 539 is heavier than the other end, which has a notch, so that the piece 539
39 has a tendency to rotate clockwise due to its own weight, and this movement is prevented by a pin 540 provided on the third locking plate 535. A claw 542 fixed to a shaft 541 is attached to one end of the piece 539.
The upper end of the spring 54 is locked, and the claw 542 is connected to the spring 54.
3 provides a clockwise rotational habit, and this movement is prevented by a pin 544 provided at the other end of the pawl 542. Both ends of the shaft 541 are rotatably supported by the partition plate 506 and the device side plate 518, and the middle portion thereof has a square cross section, to which the second stopper 705 of the second alignment device is attached. It is being

The sheets stacked on the sheet laminate 515 as described above have one end in contact with the second stopper 705 and the other side end pressed by the second alignment lever. Upon receiving and completing the binding seal operation, the fourth plunger 5
21 is excited. When the fourth plunger 521 is excited, the first locking plate 522 rotates counterclockwise around the shaft 523, the roller 526 is pushed downward, and the second locking plate 525 moves together with the shaft 527. Rotate clockwise. By this, armrest 5
28 is pushed down, and the facing roller 529 presses the upper surface of the laminated sheet located on the sheet laminated plate 515 through the opening 531, and transfers the laminated sheet to the lower fifth conveying roller 534.
This causes the fifth layer of the laminated sheet to
Conveyance on the conveyance path E becomes possible (see FIG. 15).

On the other hand, as the second locking plate 525 rotates clockwise, it pushes the pin 536, so the third
The locking plate 535 rotates counterclockwise about the shaft 537, thereby disengaging the piece 539 from the pawl 542. Therefore, the second sheet stopper 705 is in a free state, so it is pushed down by the tip of the laminated sheet conveyed by the fifth conveyance roller 534, and the laminated sheet is pushed down by the second sheet stopper 705. The paper passes through the top and is conveyed to the next stamping section (see Fig. 16).
