Description

Detailed Description of the Invention (Field of Industrial Application) This invention relates to a bookbinding machine described in Japanese Patent Application No. 54-146683 (Japanese Unexamined Patent Publication No. 56-69196) filed by the same applicant as the present applicant. Concerning improvements to inventions.

(Prior art) The bookbinding machine of the prior invention consistently performs each process from folding copies sequentially made by a copying machine in half, aligning them, binding them, sealing them (perforating them), stamping them, and discharging them. It is characterized by being carried out continuously. In each process, a detection device is provided to detect a jam in the sheet. Among the sheet jams, the sheet jam after the signing is bound has less flexibility and is difficult to remove. In order to facilitate taking out the sheet, the conveyance roller located at the top of the sheet may be moved from there. However, in devices with such a mechanism, after removing a jammed sheet, the user may forget to return the conveyance roller to its original position due to the sense of relief, and bookbinding may continue in this forgotten state. If this happens, there is a problem in that subsequent sheets will jam.

(Objective) The object of the present invention is to provide a bookbinding machine that solves the problems of the prior invention described above.

(Structure) The present invention provides a transport roller that can be retracted from the transport path, and a guide that can take a first position for guiding the supplied sheet into the bookbinding machine and a second position for discharging the same sheet to the outside of the bookbinding machine. plate, and when the conveyance roller is retreated from the conveyance path,
When the guide plate is moved from the first position to the second position and the conveyance roller is forgotten to be returned to the conveyance path, subsequent sheets are prevented from entering the bookbinding machine. It is.

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

FIG. 1 is an external view of one row of the bookbinding machines described above. This bookbinding machine can fold, align, and
Folding equipment, alignment,
Equipped with binding, sealing and sealing devices,
By using this bookbinding machine in combination with a copying machine, you can make copies of certified copies, extracts, and other documents.
Bookbinding can be performed automatically.

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 extract) as an example, the construction, operation, function, etc. of the bookbinding machine Y will be explained, focusing on the bookbinding machine Y, while describing the production process in order.

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

The original certified copy is shown in Figures 1 and 2.
Document feeding device 40 arranged on the top plate of copying machine X
0, the document is guided to an image scanning section (not shown) of the copying machine X, where information on the original document is scanned, and then the document is discharged onto the document discharge tray 401. The information on the original document is scanned by the above-mentioned scanning unit and transferred to the information recording medium (photosensitive drum and its peripheral devices) 402.
The data is copied onto a copy sheet (hereinafter simply referred to as a sheet) S via the . The sheet S on which the original information has been copied is delivered to the sheet discharge port 4 formed in the copying machine
03, and is transported toward the bookbinding machine Y. On the side of the bookbinding machine Y facing the copying machine A sheet introduction port 501 is formed.

As shown in FIG. 3, the sheet S discharged from the sheet discharge port 403 of the copying machine , the sheet is conveyed toward a sheet carry-in roller 502 disposed beside 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. Note that the carry-in roller 502 and the first conveyance roller 504 are
Through the through holes 503a and 503b drilled in the first sink plate 503, a portion of each peripheral surface is
Steel balls 502a and 504a are exposed on the upper surface of the first sink plate 503, and steel balls 502a and 504a are provided on each exposed peripheral surface.
The steel balls are brought into contact with each other by their own weight, and the sheet is held and conveyed by each steel ball and each roller (hereinafter, the structure of this type of conveyance roller is simply referred to as a conveyance roller with a ball roller structure. ). A feature of this conveyance roller having a ball roller structure is that the sheet conveyed by the ball roller can be easily moved in a direction other than the direction in which the sheet is conveyed by the conveyance roller.

By the way, by the carry-in roller 502, the first
The rear end (the left end in FIG. 4) of the sheet S conveyed on the sink plate 503 touches the carry-in roller 50.
Immediately before it leaves the paper 2, its tip is conveyed by the first conveyance roller 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). .

In addition, the sheet introduction port 501 and the carry-in roller 50
In the middle part between 2 and 2, as shown in Figure 3, there are
A movable guide plate 507 is disposed along the first sink plate 503. This movable guide plate 507 moves the next sheet carried in from the copying machine to the bookbinding machine when the sheet S conveyed by the carry-in roller 502 does not reach its first position even after a predetermined time has elapsed. It functions to expel water to the outside. Whether or not the sheet S has reached the first position is determined by a first sensor SW 1 that detects the presence or absence of a sheet placed near the carry-in roller 502 across the sheet carry-in path, and by a first sensor SW ₁ of the first conveyance roller 504. Nearby,
The second sensor SW ₁ is arranged in the same manner as the first sensor SW 1.
Detected by sensor SW ₂ . That is,
After the leading edge of the sheet S traveling along the first sheet conveyance path A is detected by the first sensor SW ₁ ,
If the second sensor SW ₂ does not detect it after a predetermined period of time (according to the timer), the flange 508 is energized and the movable guide plate 507 rotates counterclockwise around its support shaft 507a, as shown in FIG. The next sheet carried in from the copying machine X is discharged above the bookbinding machine by rotating to the position indicated by the chain line 507A. Further, this plunger 508 is energized when a micro switch 547 (described later) is activated, and rotates the movable guide plate 507 counterclockwise around its support shaft 507a, so that the next sheet to be carried in from the copying machine X is rotated. Binding machine Y
to prevent subsequent sheets from being conveyed into the bookbinding machine Y. This prevents continuous sheet jamming. Note that the operation of the movable guide plate 507, that is, the plunger 508
With the excitation of , a copying command from copying machine X is awaited, copying of the next original document and feeding of the next sheet are cut off, and the operation of the sheet conveyance system of bookbinding machine Y is stopped. As mentioned above, the first sink plate 50
When the occurrence of sheet jam on the bookbinding machine Y is detected, the top plate 509 (see Fig. 1) of the bookbinding machine Y, which is configured to be openable and closable with respect to the main body of the bookbinding machine, is opened.
The first conveyance path of the sheet S is exposed, and the jammed sheet is removed.

When each of the first and second sensors described above detects the sheet S within a predetermined time, the sheet S is oriented along the partition plate 506, which is substantially orthogonal to the first sheet conveyance path A. second conveyance path B (second
(see figure) and is conveyed on the first sink plate 503. The sheet introduction section 100a of the folding device 100 corresponds to the downstream side of the second conveyance path B (see FIG. 5). The conveyance of the sheet S to the folding device 100 is carried out by a conveyance roller (which conveys the sheet by selectively moving steel balls toward and away from the circumferential surface of a rotating roller, sandwiching the sheet between the roller and the steel balls). (Hereinafter, this will be referred to as a ball solenoid roller.)
It is carried out by. The above-mentioned first ball solenoid roller 51 is located at the corner of the first sink plate 503 near the partition plate 506 and the folding device 100.
0 is placed. This first ball solenoid roller 510 has a sheet S that is connected to the first sink plate 50.
In a state where the sheet does not reach the first position on 3 and is not detected by the second sensor SW ₂ , the sheet conveying function is in a state where it is canceled. Therefore, when the sheet S is detected by the second sensor SW ₂ , the first ball solenoid roller 510 functions,
The sheet S travels along the second conveyance path B and is sent to the folding device 100. After the sheet S is folded in half by the folding device 100, the sheet S is folded in half by the folding device 100, and then
It is conveyed on the sink plate 511 toward the third conveyance path C by a second conveyance roller 512 having a ball roller structure.

The second sink plate 511 is located below the first sink plate 503 and closer to the folding device 100.
03, and its folding device 1
The end closer to 00 corresponds to the sheet discharge section 100b of the folding device 100. This second sink plate 51
The sheet S conveyed onto the sheet S has a side edge in the direction of travel, that is, a leading edge (left side in FIG. 5).
It is temporarily stopped by contacting a sheet stopper 5131 arranged substantially perpendicularly to the third conveyance path C of the sheet from the folding device 100 to the first flow plate 511 (this The stopping position of the seat S is hereinafter referred to as the second position of the seat).
In this second position, the traveling direction of the sheet S is changed by approximately 90 degrees. That is, the sheet S is
At the same time when the second position is reached, the second conveyance roller 512 is conveyed by a third conveyance roller 513 with a ball roller structure, which is mounted on another spindle that rotates substantially orthogonally to the spindle of the second conveyance roller 512. , and is guided by a sheet stopper 5131, and is conveyed along a fourth conveyance path D that is substantially perpendicular to the third conveyance path C (see FIGS. 6 and 7).

At this time, in order to reliably change the direction of the sheet and convey the sheet in the correct direction, the conveying force of the conveying roller 513b on the leading edge side in the sheet conveying direction after the direction change is transferred to the conveying force of the conveying roller 513b on the rear end side.
It is better to make it larger than that of a. In order to increase the conveying force of the roller 513b on the tip side, either the pressure contact force with the steel ball 513b in contact with it is increased, or the diameter of the steel ball 513d is increased to increase the contact pressure. Alternatively, the peripheral surface of the roller 513b may be roughened or provided with irregularities to increase the frictional force, or the material of the roller 513b itself may be changed to a material having a larger coefficient of friction. By doing this, the sheet after the direction change is not pushed from the rear end side.
Seat stopper 51 is always led by the tip side.
It is conveyed straight along 31. At this time, as shown in FIG.
By tilting the sheet by a slight angle θ toward the direction C perpendicular to the direction C, the sheet is transported while reliably contacting the sheet stopper 5131.
More preferred.

The sheet S whose sheet conveyance direction has been changed at the above-mentioned second position is stored in 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. (referred to as the seal section) 514. This sheet seal part 51
The sheet S conveyed to the sheet laminate plate 515
For the time being, I am stocked up. The sheet laminated plate 515 has its sheet stacked surface located at a lower position than the sheet guide surface of the second flow board 511 by a height corresponding to the maximum stacked amount of sheets stored on the sheet laminated plate 515. It is arranged like this. In addition, a sheet carrying-in section 514a of the sheet marking section 514 corresponding to the sheet feeding side of the second sink plate 511 (right side in FIG. 6) has a tip end of the sheet S carried into the sheet marking section 514.
Bend Sa toward the above sheet lamination surface,
In addition, a sheet guide member 516 is provided so that the height of the upper surface of the sheets stacked on the sheet laminate plate 515 is lower than the height of the sheet guide surface of the second flow board 511. . This sheet guide member 516 is moved to the second sink plate 5 by a fourth conveying roller 517 having a ball roller structure.
When the sheet S is carried from above 11 toward the top of the sheet laminate 515, the leading edge of the sheet S is
If Sa is attached to the rear edge Sb of another sheet previously stocked on the laminate 515 (see FIG. 8) or the binding/sealing device 200 (see FIG. 9) disposed in the sheet sealing section 514, This serves to prevent the sheet S from colliding with each other and preventing the sheet S from being carried into the sheet sealing section 514. That is, when the leading edge Sa of the sheet S carried into the sheet sealing section 514 is curled or folded, the sheet S is transferred to the second flow board 5.
11, from above, in the same state (with no sheet guide member 516 disposed), insert the sheet sealing part 51.
4, the sheet S is guided upward from the predetermined path by the curl or fold itself, or by the buoyant force that acts on it as the sheet advances, and the sheet is bound. There is a possibility that the sign device 200 collides with the upwardly extending portion of the sheet laminate 515 and its progress is blocked.

Further, even if the sheet S itself has no curl, the sheet stacked on the sheet laminate plate 515 will be folded by the folding device 100.
Because it is folded in half, the bulge at the fold may change due to changes in humidity during use or subtle changes in the degree of crease, even when the same number of sheets are stacked together. It is expected that the height of the stacked sheets will not be constant. Therefore, when the height of this stacked sheet becomes higher than the height of the sheet guide surface of the second flow board 511 due to its expansion, the leading edge of the next sheet is already stacked. This causes the problem that the rear end of the seat collides with the rear end of the seat, and its progress is blocked. Therefore, the sheet guide member 5 described above
16 to the sheet loading section 51 of the sheet sealing section 514.
4a, the second sink plate 511
Sheet S carried into the sheet sealing section 514 from above
Since all of the sheets are transported or stacked at a height lower than a predetermined height without being affected by the presence or absence of curls or folds or the degree of bulge in the folds, all of the above-mentioned problems are eliminated.

Note that a third sensor SW ₃ is disposed near the fourth conveyance roller 517 to detect the presence or absence of a sheet in the same manner as the sensors described above. The third sensor SW ₃ is a sensor for detecting whether or not a sheet jam occurs while the sheet S is being conveyed from the second conveyance path B to the third conveyance path C. The tip of S is the second
If the time required from being detected by the sensor SW ₂ to being detected by the third sensor SW ₃ has passed a predetermined time (preset by a timer) during normal transportation, the above-mentioned The sheet jam is detected in the same manner as between the first and second sensors, and the movable guide plate 507 is activated (see FIG. 3).

By the way, as described above, the sheet is placed on top of the sheet S carried into the sheet sealing section 514 without causing a sheet jam, in the same position as it was when it was carried in,
When the next sheet is stacked on top of it, the sheets are likely to be misaligned with each other. Therefore, if sheets in an irregular state are bound and sealed as they are using the binding and sealing device 200, not only will the quality of the certified copies be poor, but also sheet jams will occur during the process of transporting the sheets to the next process. There is a risk. Therefore, it is necessary to align the stacked sheets with each other in the sheet marking section 514. This alignment of the sheets is done in the fourth step above.
A first aligning device 600 for aligning the leading edges Sa of sheets traveling along the conveyance path D, and a fifth conveyance path E (see FIGS. 1 and 2) that is substantially orthogonal to the fourth conveyance path D. A second alignment device 700 (first
(see Figure 1).

The first alignment device 600, as shown in FIG.
An alignment roller 601 disposed horizontally and substantially orthogonal to the fourth conveyance path D; and a pressing member 602 disposed substantially horizontally that swings toward and away from the alignment roller 601 from below. , an L-shaped first alignment lever 603 arranged 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 603
However, the opening 515 provided in the sheet laminate 515
It is designed to swing through a. 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, and is substantially perpendicular to the sheet laminate 515 and has an opening 515b thereof. a second alignment lever 701 disposed through the second alignment lever 701; a support member 703 that holds the second alignment lever 701 and is swingable about a support shaft 702;
A second plunger 704 having an actuating piece 704a connected to the tip of the plunger 704, and a fifth plunger on the opposite side thereof.
A second stopper 705 is provided substantially perpendicularly to the transport path E side. Second alignment lever 701
In the normal state, that is, the second plunger 70
When the plunger 704 is de-energized, it is tilted outward as shown by the dashed line, and when the plunger 704 is energized, it is held in a substantially vertical position as shown by the solid line. Second alignment lever 701 in the excited state
The distance between the second stopper 705 and the second stopper 705 almost matches the widthwise dimension of the sheet S used during bookbinding.

Sheet S carried onto sheet laminate plate 515
are aligned as follows by the alignment devices 600 and 700 configured as described above. First, along the fourth conveyance path D, the sheet laminate 515
The rear end Sb of the sheet S carried upward is detected by the third 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 excitation time continues until the leading edge of the sheet S hits the first alignment lever 603. 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
The sheet S rotates around , becomes vertical, and presses the side edge of the sheet S against the second stopper 705. 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 energizing time for the first and second plungers is so short that this 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 is retracted so as not to interfere with the next sheet entering onto the sheet laminate.

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 200 and one punch 202 (see FIG. 9).
The sheet laminated at the third position (1
It has the function of simultaneously binding and punching holes for seals on sheets (which may be sheets). Each stapler 201 and punch 202 is connected to a crank mechanism 2
03 and the swinging rod 2 that swings through the connecting rod 204
They are each driven by the swinging motion of 05. 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 . Further, the punch 202 is disposed below the swinging rod 205, and each punching shaft thereof is located inside each stapler 201, respectively. Each of these staplers 201 and punches 202
are arranged such that the binding portion and perforation portion thereof are located above the side edges of the sheets stacked at the third position. The sealing device 200 uses the exposure signal that is output every time one document is exposed in the copying machine X as a clock pulse, and when the exposure of all the documents is completed as planned, the operator presses a switch and outputs the seal and stamping command signal. Each time the operation of the buffer memory and the second plunger 704 of the bookbinding machine Y is completed, the data is retrieved from the buffer memory, and when there is a signature signal in the retrieved signal, or when a scheduled The operator presses a switch to issue a signature when there is a signature stamping command signal in the signal, or after exposure of all scheduled originals has been completed and the operation of the second plunger 704 of bookbinding machine Y has been completed in order to align the final copy. It is activated when a stamping command is issued; otherwise, for example, when the sheet jams in the middle of each of the above-mentioned conveyance paths and the second plunger 704 is not activated, or when copying If the repeat is not completed and copying of the sheet continues, or if the seal stamping command has not been issued, the operation is not performed. Therefore, defective binding is reliably prevented, and by not issuing a signature sealing 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 remains disengaged from the spring clutch 520, and the gear _G3 freely rotates with respect to the shaft _G3a . Therefore, from the main shaft G _1a to the gear G ₂
The power transmitted through G3a is not transmitted to the shaft _G3a , so the crank mechanism 203 does not operate, and the binding and sealing operations are not performed.

Also in this bookbinding machine, when a signature signal is issued, the second plunger 704 of the second aligning device 700 is excited. This is because when the number of sheets stacked on the sheet laminate plate 515 is small, the second plunger 70
4 is excited and the second alignment lever 701 moves the sheet S.
This is because, when the excitation is released and the alignment lever 701 returns to its original position by pushing the side edge of the seat S, the seat S may bounce back due to the force of its own waist and may not be aligned. Since it is not preferable to bind and seal in such an uneven state, when binding and sealing, the second plunger 704 is energized again and the alignment lever 701 is pressed against the side edge of the sheet S while binding and sealing is performed. It's summery. At this time, the excitation of the second plunger 704 is canceled by the switch 207, which indicates that the binding seal is completed.
(See FIG. 12).

This switch 207 is operated by the cam plate 206 which 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 the switch 207 outputs a binding seal operation completion signal, this signal causes the stapler 20 to

It is rotatably attached to the side plate 518 via a spring 524, and is given a clockwise rotational habit by a spring 524. A roller 526 provided at one end of the second locking plate 525 is locked in a recess provided at the other end of the first locking plate 522 . The second locking plate 525 is arranged parallel to the first locking plate 522, and the bases of two arm rods 528 are fixed to a shaft 527 that is the center of its swing.

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 plate 515 are
With one side end in contact with the second stopper 705 and the other side end pressed by the second alignment lever, the binding seal operation is performed, and when this is completed, the fourth plunger 521 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. As a result, the tip of the arm rod 528 is pushed down, and the opposing roller 529 presses against the upper surface of the laminated sheet to be released from the sheet laminated plate 515 through the opening 531, thereby transporting the laminated sheet to the lower fifth conveyor. Since it is pressed against the roller 534, the laminated sheet can be conveyed on the fifth conveyance path E (see FIG. 15). On the other hand, the second
As the locking plate 525 rotates clockwise, it pushes the pin 536, so the third locking plate 535
rotates counterclockwise around 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 leading end of the laminated sheet conveyed by the fifth conveyance roller 534, and the laminated sheet is pushed down by the second sheet stopper 705.
and is conveyed to the next stamping section (first
(See Figure 6).

If the laminated sheet becomes jammed during this conveyance process, the jammed laminated sheet is taken out as follows. First, tilt the lock release lever 545 90 degrees clockwise. Then, it is fixed to the tip of the support shaft and takes a vertical position in the normal state, and its lower end touches the upper surface of the first locking plate 522, causing the clockwise rotation of the first locking plate 522. The half-moon cam 546, which had been preventing movement, rotates 90 degrees and assumes a horizontal position. As a result, the half-moon cam 546
The first locking plate 522 locks the spring 52 by the notch.
4, the roller 526 provided on the second locking plate 525 is pushed upward, and the shaft 527 is rotated counterclockwise. When the shaft 527 is rotated by a certain degree, the first locking plate 522 and the second locking plate 52 are rotated by the rollers 526.
5 is disengaged, the arm rod 528 can be manually rotated freely counterclockwise and brought down. After the obstruction on the cover 530 is removed in this manner, the tip of the cover 530 is lifted and the cover 530 is rotated about the axis on which the bracket 532 is attached to remove the jammed laminated sheet.

Above the half-moon cam 546, this half-moon cam 54
A micro switch 547 is provided, which has an actuator actuated by a cam surface of 6 and is turned on and off by the rotation of a half-moon cam 546, and when this micro switch 547 is turned on, Plunger 508 shown in FIG.
operates to move the movable plate 507 to its supporting shaft 507a.
The next sheet carried in from the copying machine X is discharged above the bookbinding machine Y by rotating clockwise around the center, so that the next sheet is not inserted into the bookbinding machine.

Further, when the micro switch 547 is turned on, an alarm display lamp provided on the operation panel of the main unit lights up. This is a warning display to remind the user not to forget to put the armrest 528 back on the cover and reset it after taking out the jammed sheet and putting the cover 530 on.

In this bookbinding machine, the main switch of the main unit may be turned off in conjunction with the micro switch 547.

The above has described how to deal with a jam in this conveyance process.Next, when the fifth conveyance path E is normally fed without any jam, the fifth conveyance roller 534 moves the The sheet S conveyed along the path E is sent to the sheet stamping section 550. The sheet S sent to this stamping section is transferred to the stamping device 30 of the sheet stamping section 550.
0 is stamped, and then the sixth conveyance path F
The sheet is discharged through the sheet discharge section 560.

(Effects) According to the present invention, when the conveyance roller is retracted to take out a jammed sheet in the conveyance path, the movable guide plate is moved to the position where the subsequent sheet is discharged, so that the subsequent sheet is removed from the bookbinding machine. This can prevent subsequent sheets from jamming.
