Abstract

PURPOSE:To obtain a copy group bound into a desired book by starting copying operation from the beginning when the copying operation is restarted by stapling and discharging all copies in a book binding device when a copying machine is in an abnormal state such as jamming. CONSTITUTION:When an abnormality signal of abnormality, etc., is sent from the CPU41 of the main copying machine 1 to the CPU40 of the book binding device, it is checked whether or not the counter of an entrance counter 5 coincides with the counter of a stack entrance sensor 22. When not, the operation is held until the coincidence is obtained. Then when the coincidence is obtained, namely, when copies which enters the book binding device 2 are all passed through the sensor 22, a timer 1 counts up to its optional set number and a stapler is turned on. Then the timer 2 clocks the timer required for the stapling operation. When the timer 2 counts up to the time, a discharging motor is turned on to rotate a discharging belt 32 and the stapled copy group is discharged by a discharging claw 33.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bookbinding device that stacks and staples copies ejected from a copying machine.

When a set of manuscripts consisting of multiple sheets is copied using a copying machine,
Conventionally, staplers (trade name: Stapler) are used to manually staple one corner or 2.3 points on the - side.

Recently, recycled automatic document feeders (RADFs) have been used as part of office automation, in which a set of originals is automatically fed onto the contact glass of a copying machine in a single pass. A single exposure is performed on a fed sheet, the document is fed through circulation a predetermined number of times, and a series of copies are continuously ejected from the copying machine in a predetermined number of copies. Therefore, if a simple bookbinding machine that can automatically staple each set of consecutively output copies is connected to the copy output port of a copying machine, the bookbinding work can be done without manpower. First, the bookbinding work is speeded up, which is convenient.

As a bookbinding device for this purpose, for example,
0-180893 discloses a receiving means for receiving and transporting copies discharged from a copying machine forward; an intermediate stacking means for stacking copies received from the copying machine through the receiving means in the order in which they were received; A bookbinding apparatus has been disclosed that has a finishing device that staples and finishes a group of copies stacked on a stacking device, and a device that discharges and stacks the group of copies finished by the finishing device outside the machine.

Now, in the case of bookbinding devices used in combination with copying machines, conventionally,
Generally, when an abnormality such as a jam occurs on the copying machine side and the copying operation is interrupted, the bookbinding device is stopped in its current state. Therefore, when the copying machine resumes work, it is necessary to send a copy from the page after the interruption. Alternatively, before restarting work on the copying machine, the operator must remove the group of copies in the bookbinding device and turn the power to the bookbinding device on and off to clear the current state and return to the initial state. Ta.

L1 The present invention takes into consideration the above-mentioned problems of conventional bookbinding devices used in combination with copying machines.The present invention has been developed so that even if the copying operation is interrupted due to an abnormality such as a jam in the copying machine, copying can be started from the beginning when copying is resumed. It is an object of the present invention to provide a bookbinding device which, once started, produces a desired set of bound copies.

Structure In order to achieve the above-mentioned object, the present invention provides a bookbinding device having the above-mentioned structure, in which, in response to an abnormal signal from the copying machine, all the copies in the bookbinding device are bound with staples and then ejected from the machine. The present invention is characterized in that a control means is provided for controlling the finishing means and the discharging means of the apparatus.

Embodiments of the present invention will be described in detail below 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 copies discharged from a copy outlet of the copying machine 1 are guided into the bookbinding device 2 by entrance rollers 3 and 4. The copy that has entered the bookbinding device 2 is transferred to the transport roller 6
．． 7: Punch 10 for holes in 8, 9 and guide plates of each part.
The location will be sent continuously. When punching a copy, the stopper 12 is inserted into the conveyance path, the leading edge of the copy is brought into contact with it and stopped, and the punch 10 is used to punch a hole. After completing the work, the stopper 12 is retracted to the position indicated by the broken line to release the hole punching, and the copy is transported by the transport rollers 13 and 14. If you want to eject the copies without stapling them, set the branch claw 19 to the position shown by the broken line and use the ejection rollers 15 and 16 to
The paper is discharged to the paper discharge tray 18 outside the machine.

When stapling a group of copies, the branch claw 19 is set to the position shown by the solid line, and the copies are sent to the stack section along the guide via conveyance rollers 20, 21; 23, 24. The stacking section is provided with a feed roller 25 that is movable between a position shown by a solid line and a position shown by a broken line in the figure, and feeds the copy to the stapling position.

A group of copies to be stapled is aligned by a guide fence 34, and once aligned, the group of copies is stapled by a stapler 35. After stapling, the ejection belt 32 rotates in the direction shown by the arrow in the figure, and the ejection claw 33 catches the copy group and ejects it to the paper ejection tray 31. The ejection belt 32 continues to rotate even after ejecting the copy group, and stops rotating when the ejection claw 33 turns on the home position sensor 26. The above-mentioned feed roller 25 is lifted by a solenoid (not shown) in synchronization with the ejection belt 32 so as not to interfere with ejection of the copy group.

Reference numerals 5, 11, 22, and 27 in the figure are sensors for detecting the passage of copies, and counters are provided for counting the number of copies that have passed through each sensor.

FIG. 2 is a timing chart of the operations of each of the above components. The first half, indicated by A in the figure, is the operation of parts such as sensors for each copy until the copy reaches the stack section. After repeating this several times, the second half, indicated by B, is the stapling operation and ejection. The operations are performed and the bookbinding operation is completed.

Note that this bookbinding device does not move the ejected copy group laterally, regardless of the size of the group of copies ejected from the copying machine or the ejection standard, and the bookbinding device can move the group of copies ejected from the copying machine at one place in the corner or at two places in the center. Two staplers are provided so that they can be moved laterally, and the stapler and guide fence can be moved from a reference position determined by a home position sensor to a desired position by a step motor.

FIG. 3 is a block diagram of a control circuit of the bookbinding apparatus having the above configuration. Controlled by CPU (microcomputer) 40
CPU 41 for controlling the copying machine main body 1
Data is transferred serially. Each data, such as copy size data, etc., is sent by this serial number. 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 ejection belt 32, the home position sensor of the stapler 35, and the signals from the home position sensor of the guide fence. This information is input and processed by the CPU 40, and via the driver 42, the hole punch 10, stopper claw 12, branch claw 19
．． It drives each solenoid that controls the position of the feed roller 25, the main motor of the bookbinding device, the ejection motor, and the stepping motor that displaces the stapler and guide fence. The CPU 40 and the driver 42 are mounted on one control PCB 4'3.

Further, in the bookbinding apparatus of the present invention, the finishing means including the stapler and the ejecting means are controlled by the CPU 40 as follows. The operation will be explained 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 problem with the copying machine, the copying machine will be removed immediately at the entrance. When an abnormality signal such as a jam is sent from the CPU 41 of the copying machine main body 1 to the CPU 40 of the bookbinding device, the flow proceeds to the next step. Check whether the counters (see Figure 1) match. If they do not match, wait until they match.

Thereafter, if the counters match, that is, if all the copies that have entered the bookbinding device 2 have passed through the sensor 22, and the timer 1 has counted up to an arbitrary count, the stapler is turned on. The timer 2 waits for the time required for stapling. When the timer 2 counts up, the ejection motor is turned on, the ejection belt 32 is rotated, and the group of stapled copies is ejected by the ejection claw 33. In addition, in this case, feed roller 2
5 is raised by a feed coro solenoid (not shown) so that it does not get in the way. The copy group is ejected, and the ejection claw 33
continues to rotate until the sensor 26 turns on, and when the sensor 26 turns on, the ejection motor is stopped, the belt is stopped, the feed coro solenoid is turned off, and the belt is returned to its original position.

Effects As described above, according to the present invention, in the event of an abnormality such as a jam in the copying machine, all copies in the bookbinding device are stapled and ejected. If copying is restarted from the beginning without the need for consideration, a group of correctly bound copies will be ejected from the binding device, and there will be no need for the operator to manually remove the remaining copies from the binding device before restarting copying. This is effective in reducing labor and preventing bookbinding errors.
