Detailed description of the invention 3. Detailed description of the invention
The present invention relates to a paper binding device that enables efficient image formation and paper binding operations.

A paper binding device such as a conventional IJL copying machine is connected to the main body of the copying machine, etc.
Paper sheets of the copying machine discharged from the main body are carried into a paper loading table, and after a predetermined number of sheets have been placed, the ends of the stacked sheets are stapled using a stapler or the like.

Conventionally, the above-mentioned work has been performed using a single paper mounting table.

Generally, after a predetermined number of sheets of paper have been brought in, the misalignment of the stacked paper is corrected, the binding is done with nails, etc. at a predetermined location on the edge of the stack of paper, and the paper is finally ejected. This paper binding operation requires a processing time of 1 to 15 seconds.

Therefore, if paper binding work is to be performed continuously on a single paper loading table, it is necessary to prohibit the introduction of copy paper during the paper binding work, and therefore copying in the main body of the copying machine must be stopped. .

In order to shorten this stop time as much as possible, it is possible to simplify operations such as paper processing, but if the operations are simplified, paper binding may not be performed accurately.

The present invention has been made in view of the above, and the object thereof is to provide a plurality of paper stacks, and when stacked sheets of paper on one paper stack are bound, the paper stacks on the other paper stacks cannot be bound. The object of the present invention is to provide a paper binding device such as a copying machine that allows paper to be carried in and makes continuous copies at all times.

On the lower surface of the tray 9, a belt 28 is installed along a long hole 27 over a pair of pulleys 29, one of which is fitted onto a drive shaft of a gripper moving motor 30. A protruding portion that protrudes downward from the lower surface of the gripper 21 through the elongated hole 27 is fixed to a part of the gripper 21 .

Therefore, the gripper 21 can be slid back and forth via the belt 28 by driving the gripper moving motor 30.

A microswitch 31 is provided along the rear end edge of the tray 9 to detect when the gripper 21 reaches the Baum position, with a predetermined moving position behind the gripper 7 as a home position.

Further, the sight gate 32 located at the front end of the tray 9 is fitted into an elongated hole 33 that is long in the left-right direction and perpendicular to the elongated hole 27, and a part of the lower edge is bent into a 1-1 shape. Arm portion 34
extends rearward along the lower surface of the tray 9 and is supported at its end by a support shaft 36 oriented in the left and right horizontal directions, and then has a protruding portion 35 that is further bent downward (see FIG. 6).

A plunger 38 of a side goo 1-drive solenoid 37 is locked from the rear to this protruding portion 35, and one end of a tension spring 39 is fixed to the protrusion 35. It is fixed to a protruding fixing member 40.

When the side gate drive solenoid 37 is in the OFF state and the protrusion 35 of the υ side gate 32 is pulled forward by the tension spring 39 (the state shown in FIG. 6).
, Cytogames 1 to 32 stand up towards Tray 9.
The laminated paper can be brought into contact and its edges can be aligned.

In this state, the elongated hole 3 is located in front of the front surface of the side gate 32.
3 gaps are formed.

When the side gate drive solenoid 37 is driven, the protrusion 35 of the side gate 32 is pulled rearward, and the sight gate 1-32 swings counterclockwise in FIG. 5 about the support shaft 36. , the portion protruding upward from the elongated hole 33 can be sunk downward through the elongated hole 33, and the tray 9
It becomes possible for the paper to pass over the elongated hole 33.

Next, the stapler 15 is placed in a position where it partially bites into the notch at the front right corner of the tray 9, and
The tray is stopped so that the upper surface of a is flush with the upper surfaces of the trays 1 to 9, the end of the stacked paper 50 is positioned between it and the upper binding member 15b, and the binding member 15b is lowered,
A needle can be passed through the laminated paper 50 between the receiving member 15a and the paper to be stapled.

With the above configuration, paper binding control is performed, and various settings are set by the operator. This is performed by operating buttons on the operation panel 60 provided in front of the top surface of s1.

FIG. 8 shows a plan view of a copying machine and a paper binding device. On the operation panel 60, in addition to a start button 61, a paper size setting button 62, a number of sheets setting button 63, a binding position setting button 64, etc. are arranged. There is.

The number of paper sheets setting button 63 is a button for setting the number of sheets of paper to be bound, and the binding position setting button 64 is a button for setting the binding position of the sword to 1.
This button allows you to select one of three locations.

The paper binding device 2 is configured under settings using such setting buttons.
The control system is controlled and driven.
The block diagram is shown in the figure and will be explained.

The central part of this control system is the CPU 70, which performs control operations according to programs written in the ROM 71 while utilizing the RAM 72 as needed.

Signals from a start button 61, a paper size setting button 62, a number of sheets setting button 63, a binding position setting button 64, a paper path photo sensor 65, a microswitch 31, etc. are input to the CPU 70 via an input interface 73.

The paper path photo sensor 65 is provided at the paper inlet of the paper binding device 2, and is used to detect the inflow of paper.

Control signals are also sent from the CPII 70 via the output interface 74 to the vertical transport drive motor 5, the guide claw drive solenoid 14, the tray lowering motor 12, the gripper movement motor 30, the gripper drive solenoid 23, the side gate drive solenoid 37, and the stapler. It is output to the drive solenoid 16, etc.

Paper binding control is performed in the control system as described above.

The procedure will be explained below.

First, the paper size, number of sheets, and binding position are set using the paper size setting button 62, the number of sheets setting button 63, and the binding position setting button 64.

The CPU 70 determines the moving distance of the gripper 21 from the sheet size and the stapling position.

When the start button 61 is pressed, the paper binding device 2 is in a standby state (as shown in FIG. Guide claw 1
3, turn on the guide pawl drive solenoid 14 and tilt it toward the belt 6 side.

At this time, the guide claw 13 of the upper tray 9a is separated from the belt 6.

Then, in the lower tray 9b, the gripper 21 is moved backward by the reverse drive of the gripper moving motor, and stopped at the home position by the operation of the microswitch 31, and from there it returns to the position corresponding to the paper size (side gate 32
Move forward until the distance from the paper size is slightly larger than the paper size.

The gripper moving motor 30 is a stepping motor, and can move the gripper 21 to a desired position by driving it by a predetermined pulse amount corresponding to the paper size.

When a copied sheet is brought in from the copying machine 1 in the above state, the sheet is attracted to the belt 6, conveyed downward by the vertical transport 3, and peeled off from the belt 6 by the guide claw 13 of the lower tray 9b. lower tray 9b
be carried above.

At this time, the paper pass photo sensor 65 detects the carryer and sends a signal to the CPU 70, which confirms the carry-in and counts the number of paper passes.

The carried paper slides on the inclined tray 9b and stops when its leading end touches the head guide 20.

Similarly, sheets of paper that are brought in one after another are stopped at the same position and stacked while being aligned in the left and right direction.

When the set number of sheets are stacked on the tray 9b in this way, the guide pawl drive solenoid 1 of the lower tray 9b
4 is activated, the guide claw drive solenoid 14 of the upper tray 9a is turned on, and this time the guide claw 1 of the upper tray 9a is turned on.
3, the paper is carried onto the upper tray 9a (second
The figure shows this situation).

In the lower tray 9b, the gripper 21 is moved forward, the rear end of the stacked paper 50 is pushed by the compiler wheel 26, and the stacked paper 50 is pressed against the side gate 32 to align the paper in the front and rear direction.

Next, the gripper 21 retreats and returns to the position where it can be gripped (the position where it moved forward from the home position and stopped),
The gripper drive solenoid 23 is driven and the rear end of the stacked paper 50 is held.

Then, the side gate 32 is sunk below the tray 9b by the drive of the side gate driving lens 37, and the moving distance of the gripper 21 determined as described above (the number of steps in the gripper moving distance - 30) is ('j gripper moving distance). The motor 30 is rotated in the forward direction to advance the laminated paper 50 to a predetermined position, and at the same position the stapler drive solenoid 16 of the stapler 15 is driven to staple the paper (see FIG. 7).

When binding paper at two or three locations, the laminated paper 50 is further advanced to a predetermined position and the paper binding is performed.

After the paper is bound in this way, the laminated paper 50 is further advanced, the gripper drive solenoid 23 is activated, the gripper 21 is opened, υ1 is ejected, and then the gripper 2
1 retreats and the paper binding operation is completed.

While the lower tray 9b is undergoing the paper binding operation (work in which the stacked paper 50 is bound and ejected after a predetermined number of sheets have been brought in), the upper tray 9a
Paper is continuously carried in.

After the stacked paper 50 in the lower tray 9b is bound and discharged in this way, the 1-lay lifting motor 12
is driven, and the trays 9a and 9b unexpectedly come to a position where the upper tray 9a corresponds to the stapler 15 and stop.

During this time, sheets are being carried into the upper tray 9a.

In this way, when the number of sheets carried into the upper trays 1 to 9a reaches a predetermined number, the guide claw drive solenoid 14 of the lower tray 9a is set to 0, and the guide claw drive solenoid 14 of the lower tray 9b is turned ON. Thereafter, the paper is carried into the lower tray 9b, and the paper binding operation is performed on the upper trays 1 to 9a in the same manner as described above.

FIG. 3 shows this state.

After the paper binding operation on the upper I-rays 9a is completed, the 1-lays 9a and 9b are raised again and return to the state where the paper is carried into the lower tray 9b at the position above the tray,
This means that one cycle will end.

In this embodiment, the paper loading is stopped by repeating the cycle described above. The paper binding operation is performed continuously and in parallel without any interruption.

Therefore, operations from copying to paper binding can be performed efficiently without having to temporarily stop the operation of the copying machine for paper binding.

In this embodiment, two trays, upper and lower, are used, but three or more trays may be provided to sequentially carry in sheets and bind the sheets.

In this way, when there are three or more trays, if the loading of paper ends on another 1-lay during paper binding (this happens when the number of sheets to be bound is small), then another It is possible to continue carrying paper into the tray, it is possible to bind a small number of sheets, and it is possible to meet a variety of requests.

The present invention can perform the process from forming both edges to binding the paper continuously without having to wait for image formation, enabling efficient work and realizing a high-productivity system. can do.
