Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a receiving means for receiving a copy ejected from a copying machine and a copy outputted from the copying machine and transporting the copy forward, and a copy receiving means for receiving the copy received from the copying machine through the receiving means. An intermediate stacking means stacks the copies in the order in which they are received, a finishing means performs finishing by stapling the copies stacked on the intermediate stacking means, and discharges the copies finished by the finishing means outside the machine and stacks them. A bookbinding apparatus is disclosed having means for.

However, with this bookbinding device and other known bookbinding devices,
The stapler is installed at one fixed position, and moves copies of each size that are ejected to different positions according to the copy ejection standards of the copying machine to a position suitable for stapling.
It is common to perform stapling work after aligning a group of copies. Therefore, the stapling position for a group of copies can only be stapled at one location regardless of the copy size, copy direction, etc.

In the case of small-sized copies, there are disadvantages such as insufficient movement for stapling or difficulty in aligning the sheets properly.

This invention relates to a bookbinding device that binds with staples.

Prior Art When a set of original documents 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, recycling-type automatic document feeders (RADFs) have been used as part of office automation. 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 from a copying machine 1 - Hiroshi The present invention provides a copying machine that solves the above-mentioned drawbacks of the conventional bookbinding device that is connected to a copying machine and uses a stapler to bind a group of copies ejected from the copying machine. Even when the copy ejection standard of 2 is in the center, that is, when the position of the edge to be bound of a group of copies when stacking differs depending on the copy size,
It is an object of the present invention to provide a bookbinding device that is capable of stapling a fixed position from an edge without moving a group of copies, and that is capable of simultaneously stapling two places in the center of one edge of a group of copies. do.

Structure In order to achieve the above object, the bookbinding apparatus of the present invention has the above structure, in which the finishing means is provided with two movable stapling means, a means for simultaneously moving the stapling means is provided, and a copy group is moved. It is characterized by providing a control means for controlling the moving position of the stapling means and its activation/deactivation, respectively, based on the information on the staple position and the number of staples, or controlling the moving position of the stapling means on the basis of the information on the size of the received copy. shall be.

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 to make holes in 8, 9 and the 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 punching operation, 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 one-branch nail 19 is set to the position shown by the solid line, and the copies are sent to the stack section along the guide via Wi feed rollers 20, 21: 23, 24. The stack unit is provided with a feed roller 25 that can be moved between a position shown by a solid line and a position shown by a broken line in FIG. 1, 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.

Now, the position of the paper discharged from a copying machine or the like in the direction perpendicular to the conveyance direction differs depending on the paper conveyance standard. Third
The figure shows BS, A4. It shows the ejection position of each size of paper, B4 and A3, and FIG. 4 shows the ejection position of each size of paper when the right end surface of the paper is taken as the conveyance reference in the figure.

In the case of edge reference, when stapling one corner of the paper, even if the stapler is fixed, if the corner to be stapled is shown in Figure 5, for example, the paper should be oriented so that the leading edge is on the right side. By determining and discharging sheets, sheets of each size can be stapled without changing the position of the stapler.

However, in the case of the center standard shown in Figure 3.

If the stapler position is fixed, it is necessary to move the ejected sheets one by one laterally so that the corners to be stapled are at the stapling position, or to move the stacked copies. there were.

Furthermore, it was not possible to staple the two central locations of the leading edges of the group of sheets to be discharged.

In the bookbinding apparatus of the present invention, in order to solve the above-mentioned problems, the stack section explained in FIG.
Two staplers 35 are provided so as to be movable in a direction perpendicular to the copy conveyance direction.

Guide fences 34 for guiding both side edges of the copy are also provided so as to be movable in a direction perpendicular to the copy conveyance direction. The two staplers and the two guide fences are each moved to a desired position by a stepping motor (not shown) via a wire drive device. 34B and 34D indicated by broken lines in the figure are the home positions of the two side fences, and 35B and 35D are the home positions of the two staplers, respectively. If these are not at the home position when the power switch is turned on, the stepping motor rotates until a home position sensor (not shown) detects the detection, and the guide fence and stapler are brought to the home position.

The copy size data sent from the copier main unit 1 and the stapling position, i.e., Fig. 6(a),
When the control circuit of the bookbinding device receives data from one left corner, one right corner, or two central locations as indicated by the symbol S in (b) and (c), the two staplers 35 and the guide fence 34 moves to a position corresponding to the copy size and binding position. The guide fences 3/IA, 34C and the staplers 35A, 35C shown by solid lines in FIG. 5 are the movement positions when a copy of the size shown by the reference numeral 36 is discharged to this position. If the copy size is the maximum size that can be handled by this bookbinding apparatus, as shown by reference numeral 37, the guide fence and stapler may remain at the home position. Even if the copy size is the same, the ejection position is different depending on whether the ejection reference is the center reference or the edge reference, so the guide fence and stapler positions are determined by rotating the stepping motor by the preset number of steps for each. , bring it into place. Further, when stapling is to be performed at only one location, control is performed so that only the stapler on the side to be stapled is operated. When stapling two locations in the center, both staplers are controlled to operate simultaneously.

FIG. 7 is a block diagram of a control circuit of the bookbinding apparatus having the above configuration. Controlled by CPU (microcomputer) 40
C, PU4 for controlling the copying machine main body 1
1 means that data is transferred serially. Various data, such as copy size data, etc., are sent through the serial I10. The CPU 40 receives the copy detection signals from the paper sensors 5, 11.17, 22.27, 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. entered,
These pieces of information are processed by the CPU 40, and via the driver 42, the punch 10°, the stopper claw 12, the branch claw 1, etc.
9. 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. CPU 40 and driver 42
is mounted on one control PCB 43.

Effects As described above, according to the present invention, regardless of the size and ejection position of a group of copies ejected from a copying machine, one corner or central portion can be moved without moving the group of copies. Since it is possible to staple at two locations and there is no need to move the copies, there is no need to limit the types of sizes, and the occurrence of jams and irregularities can be prevented.
