Description

Description: TECHNICAL FIELD The present invention relates to a bookbinding system for stacking copies discharged from a copying machine and binding them with staples.

Prior art When a set of multiple originals is copied by a copier,
Conventionally, a stapler (commercial stapler) is generally used to manually bind one or two corners at one corner.

Recently, a recycle type automatic document feeder (RADF) is being used as part of office automation.
In this case, a set of originals is automatically fed onto the contact glass of the copying machine, one exposure is performed for each feeding, and the originals are circulated a required number of times to feed the originals. A required number of copies are continuously ejected from the copying machine. Therefore, if a simple bookbinding machine that can automatically bind one set of consecutively ejected copies with a stapler is connected to the copy outlet of the copier, it will take time for bookbinding work. Instead, the bookbinding work is speeded up, which is convenient.

As a bookbinding apparatus for this purpose, for example, Japanese Patent Laid-Open No.

By the way, in the bookbinding device which is used by being connected to the copying machine, conventionally,
Generally, when an abnormality such as a jam occurs on the copying machine side and the copying operation is interrupted, the bookbinding apparatus is stopped in the state at that time. Therefore, when the work is restarted on the copying machine side, it is necessary to send a copy from the page after the interruption. Alternatively, before the work of the copying machine is resumed, the operator needs to take out the copy group in the bookbinding apparatus and turn on / off the power of the bookbinding apparatus to clear the state at that time and return it to the initial state. It was

The present invention has been made in view of the above problems of the conventional bookbinding apparatus that is used by being connected to a copying machine. It is an object of the present invention to provide a bookbinding system in which a desired bookbinding copy group is created by starting.

In order to achieve the above-mentioned object, the present invention has a receiving means for conveying the copy discharged from the copying machine to the receiving front side, and an intermediate stacking means for stacking and stacking the copies conveyed through the approach path in order. Finishing means for finishing by binding the copy bundle stacked on the intermediate stacking means with a stapler, and a discharge belt and discharge claws arranged on the discharge belt, and a copy bundle finished by the finishing means, In a bookbinding system having discharge means for discharging from the intermediate stack means to the stack means via a discharge path at least partially common to the above-mentioned entry path,
Based on the abnormal signal sent from the copier, collect all the copies in the bookbinding system in the intermediate stack means,
The present invention is characterized in that a control means for controlling the stapler to be bound and then discharged to the outside of the machine is provided.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing an overall schematic configuration of an example of a bookbinding apparatus to which the present invention is applied. The bookbinding device 2 is installed adjacent to the copying machine 1, and the copy discharged from the copy discharge port of the copying machine 1 is guided into the bookbinding device 2 by the entrance rollers 3 and 4. The copy that has entered the bookbinding apparatus 2 is the transport rollers 6,7;
It is sent to the position of punching punch 10 by 8, 9 and the guide plate of each part. If you want to punch a copy, insert the stopper 12 into the transport path and hit the copy tip against it to stop it.
Punch 10 to make a hole. After the completion of the punching operation, the stopper 12 is retracted to the position indicated by the broken line and released, and the transport rollers 13 and 14 transport the copy. If you want to eject the copy without setting it, set the branch claw 19 to the position shown by the broken line,
The paper is discharged to the paper discharge tray 18 outside the machine by the discharge rollers 15 and 16.

When stapling the copy group, the branch claw 19 is set to the position shown by the solid line, and the copy claw 19 is sent to the stack portion via the transport rollers 20, 21; 23, 24 along the guide. The stack portion is provided with a feed roller 25 that is displaceable between the position shown by the solid line and the position shown by the broken line in the figure, and feeds the copy to the staple position.
The copy groups to be stapled are aligned by the guide fence 34, and when they are aligned, the copy groups are stapled by the stapler 35. After stapling, the discharge belt 32 rotates in the direction indicated by the arrow in the figure, and the discharge claw 33 catches the copy group and discharges the copy group to the discharge tray 31. The discharge belt 32 continues to rotate after the copy group is discharged, and the discharge claw 33 is the home position sensor.
Rotation stops when 26 is turned on. The feed roller 25 is lifted by a solenoid (not shown) in synchronism with the discharge belt 32 so as not to disturb the discharge of the copy group.

Reference numerals 5, 11, 22, and 27 in the figure denote sensors for detecting the passage of copies, respectively, and a counter for counting the number of copies having passed through each sensor is provided.

FIG. 2 is a timing chart of the operation of each of the above components. The first half portion indicated by A in the drawing is the operation of the parts such as the sensors for each copy until the copy reaches the stack portion, and after repeating this several times, the staple operation and ejection in the latter half portion indicated by B are performed. The operation is performed, and the bookbinding work is completed.

With this bookbinding device, regardless of the size of the copy group discharged from the copying machine and the discharge standard, the discharged copy group is not moved laterally, but at one location in the corner or at two locations in the center. Two staplers are provided so as to be movable laterally so that the stapler and the guide fence can be moved from a reference position, which is positioned by the home position sensor, to a desired position by a step motor.

FIG. 3 is a block diagram of a control circuit of the bookbinding device having the above configuration. The control is carried out by a CPU (microcomputer) 40, and data is transferred serially to a CPU 41 for controlling the copying machine main body 1. By this serial I / O, each data, such as copy size data, is sent. The CPU 40 receives the copy detection signals from the paper sensors 5, 11, 17, 22, and 27, the home position sensor 26 of the copy discharge belt 32, the home position sensor of the stapler 35, and the pom position sensor of the guide fence. This information is processed by the CPU 40, and through the driver 42, punching punch 10, stopper 12, branch claw.
19. Each solenoid for controlling the position of the feed roller 25, the main motor of the bookbinding apparatus, the ejection motor, and the stepping motor for displacing the stapler and the guide fence are driven. 1 for CPU 40 and driver 42
Mounted on one control PCB43.

Further, in the bookbinding apparatus of the present invention, the finishing means including the stapler and the discharging means are controlled by the CPU 40 as follows. The operation will be described below with reference to the flowchart of the copying machine jam subroutine shown in FIG.

Even if the copying machine jam subroutine is entered, if there is no abnormality in the copying machine, it immediately exits at the entrance. An abnormal signal such as a jam is sent from the CPU 41 of the copying machine body 1 to the CPU of the bookbinding device.
When sent to 40, the flow proceeds to the next. Next, the counter of the inlet sensor 5 (see FIG. 1) and the stack inlet sensor 22
It is checked whether the counters (see FIG. 1) match. If they do not match, wait until they match. After that, if the counters match each other, that is, if all the copies that have entered the bookbinding apparatus 2 have passed through the sensor 22, the stapler is turned on when the count up to the arbitrary count set in the timer is performed. The timer 2 is waiting for the time required for the stapling work. When the timer 2 counts up, the discharge motor is turned on and the discharge belt
The 32 is rotated, and the copy group stapled by the discharge claw 33 is discharged. At this time, the feed roller 25 is raised by a feed roller solenoid (not shown) so as not to get in the way.
The copy group is discharged, and the discharge claw 33 continues to rotate until the sensor 26 is turned on. When the sensor 26 is turned on, the discharge motor is stopped, the belt is stopped, the feed roller solenoid is turned off, and the original position is restored. .

As described above, according to the present invention, when a copy machine jam or the like is abnormal, all the copies in the bookbinding apparatus are stapled and ejected. If copying is restarted from the beginning without any consideration, correctly bound copy groups are ejected from the bookbinding device, and it is no longer necessary for the operator to manually remove the remaining copies with the bookbinding device before resuming copying. It is effective in reducing labor and preventing binding mistakes.
