Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a sheet folding device, and more particularly to an edge folding device that folds a corner portion that overlaps a file binding side into a triangular shape by single-blade folding or the like.

■Prior Art For example, copies of various sizes can be obtained using conventionally used blueprints (diazo copies) and recent electrophotographs (transfer type copies).

Generally, A-size copies larger than A4 should be folded into A4, and B-size copies larger than B5 should be folded into B.
Fold into 5. For example, when folding A2 to A4, first fold one corner into a triangular shape (end face folding), then perform one vertical fold, and then perform horizontal 21 x diffraction (blade folding).

Conventionally, this type of sheet folding process is performed manually, which requires a lot of work, and it is not always possible to obtain an accurate folded shape. Many people do not know how to fold, and it takes time and effort to correct the folding method. Although the triangular shape of the end face fold must correspond to the sheet size, it is difficult to obtain an accurate fold shape for each size.

■Purpose The first object of the present invention is to provide an edge folding device that automatically performs edge folding of a plurality of sheet sizes, and provides an edge folding device that can obtain accurate fold lines and fold shapes for each sheet size. The second purpose is to

■Structure and ■Effects In order to achieve the above objects, the present invention includes: a folded plate that moves back and forth; a push plate that moves back and forth and up and down; a first yiA moving mechanism that drives the folded plate back and forth; 2 drive mechanism; 3rd drive mechanism that drives the push plate up and down; at least one movable register that stops and restrains a side of the sheet other than the side that forms the end face folding corner and moves to a sheet stop position and a retreat position; a plurality of registers including; a fourth drive mechanism that drives the movable register; and control that places a register corresponding to the sheet size at a sheet stop position and energizes the first drive mechanism after energizing the third drive mechanism. The means shall be provided. That is, the pushing plate is driven downward to press the sheet, and the folding plate is driven forward to fold the corner portion of the sheet into a triangular shape.

According to this, since the sheet is held down and the folding position is defined by the press plate, triangular folding is reliably performed and the folding line is accurate.

Since the sheet is set in a register corresponding to the sheet size, an accurate fold shape can be obtained for each size. Also, the fold shape may be selected, for example, by setting the sheet position in a register different from the register assigned to the size and making the fold shape different from the one assigned to the size. Further, by making the register movable and adjustable in the longitudinal direction of the sheet, various fold shapes can be set.

In a preferred embodiment of the invention, the folded plates are placed at two corners of the paper.
It has a "C" shaped flat surface with a straight part on which the sides rest, and a curved part that is continuous with the straight part and bends one side of the paper raised in the straight part. The edge has a knife for guiding the paper downward, and the first drive mechanism for reciprocating the folded plate is a link arm and a half-rotation clutch connected to the folded plate via the link arm, The second drive mechanism that reciprocates is composed of a spring member that provides a return force in the direction of the standby position and an interlocking member that is pushed by the forward movement of the folded plate to move the push plate in the same direction, and drives the push plate up and down. The third drive mechanism is composed of a solenoid and a member that is driven by the solenoid and drives the push plate downward.

According to this, with the seat stationary at a predetermined position,
The "C"-shaped straight part of the folded plate raises the corner part of the sheet, and the curved part bends the sheet, and the pressing plate presses the sheet downward during such bending of the sheet to fix the sheet. Accurate end folding can be performed with a relatively small number of mechanical elements and without complicated movement of the sheet.

Other objects and features of the present invention will become apparent from the following description of preferred embodiments with reference to the drawings. [Embodiment] FIG. Shown with the cover removed.

Note that this sheet processing machine 900 has an appearance shown in FIG. 2 when the front cover is closed, and in the most preferable embodiment, as shown in FIG.
A control signal line of the sheet processing machine 900 is connected to the copying machine 800. A control signal line for sorter 1000 is also connected to copying machine 800.

The copying machine 800 is designed to be most suitable for this combination mode, and the copy size (recording paper size), number of copies, copy feeding orientation (vertical, horizontal), stamp data (necessity of stamp, stamp position, etc.) Publisher (2 drawing types), punch data (punch required or not).

Paper discharge data (paper discharge to tray ET/or sorter 1000)
'), a start signal, an end signal, etc. are given to the sheet processing machine 900.

The sheet processing machine 900 is equipped with an operation board 11 that allows input paper size, paper orientation (vertical, horizontal), and stamp data (necessity of stamping) to be displayed.

It is now possible to set or input stamp position (2 publishers, 2 drawing types), punch data (necessity of punching), paper discharge data (paper discharge to tray ET or paper discharge to sorter 1000), start signal, etc. In addition, it can operate independently of the copying machine 800 in response to settings on the operation board 11 and operations on the board 11. When receiving a certain signal from the copying machine 800, the sheet processing machine 900 takes up the data and signal received from the copying machine 800 with priority over the settings and operations of the operation board 11. When the copier 800 does not provide the required data, the sheet processor 900
operates according to the settings and/or operations of the operation board 11.

Referring again to FIG. Copy paper is supplied from a copying machine 800 to a sheet processing machine 900 in the direction of an arrow 801. Note that when the copying machine 800 is not connected, paper is fed to the sheet processing machine 900 from the direction of the arrow 801 using an auto feeder or manual feeding.

The paper entering the sheet processing v & 900 is transferred to the vertical folding mechanism unit 100-90 @ tanning mechanism unit, knitting 200 - wing folding mechanism unit 300 - punching mechanism unit 400 - stamp mechanism unit 500 - vertical transport mechanism unit 600 - the paper ejection mechanism unit 700; and the paper ejection mechanism unit 700, which is transported in this order.

It is discharged in a direction 701 toward the tray ET or in a direction 703 toward the sorter 1000.

A drawer-shaped case is pulled out from the main body of the sheet processing machine 900 toward the front.

A power fiber connector and a signal fiber connector, which are connected to the power line female connector and signal line female connector of the sheet processing machine 900 main body, are also fixed to the case wall on the back side of the drawer-shaped case that houses each unit. These male connectors engage the female connectors when the engagers engage the latch members.

Roughly speaking, the gear that obtains the main power of the mechanical unit is exposed behind the case wall on the back side of the drawer-shaped case that houses each unit, and the aforementioned engager engages with the latch member. When this gear is in the main body of the sheet processing machine 900,
It engages with the gears of the power transmission system driven by the main motor. The gear that obtains the main power of the mechanism unit is pivotally attached to a drawer-shaped case, and is connected to the gear shaft via other gears.

Further, a paper conveyance roller of the mechanical unit is connected via power transmission means such as a chain or belt, and a clutch as necessary. Note that some mechanical units are equipped with an independent motor for driving rollers, and in this embodiment, in a mechanical unit with simple single-sheet feed control, the rollers of the mechanical unit are connected to the main power system of the main body of the sheet processing machine 900 via gears. However, in the 1" unit, where the paper feed control is somewhat complicated, an independent motor is provided in the drawer-shaped case, and the paper feed rollers in one mechanism are driven independently by the motor. ing.

Next, the configuration of each mechanical unit will be explained with reference to FIGS. 5a to 11.

First, the configuration of the vertical folding mechanism unit 100 will be explained with reference to FIG. 5a.

The vertical folding mechanism unit 100 includes a roller 104 for paper entry and a paper entry gate claw 112.3 that determines the feeding direction of 1089 paper.
vertical folding rollers 116, 118° 120, vertical folding conveyance rollers 162, 166, and end folding folding plates 197. Equipped with registers 154, 156, etc. for setting vertical folding position,
The required rollers are coupled to a drive power system (not shown) of unit 100.

The paper entry gate claw 112 is fixed to the rotating shaft 110,
This rotating shaft 110 is rotationally driven by a solenoid 114. When vertical folding is not instructed, solenoid 114
When the paper entry gate 112 is not energized and placed at the solid line position shown in the figure, the paper sent directly below the single paper sensor 174 is received by the rollers 104 and 108, but the claw 11
unit 20 and is bent downward.
Go straight to 0. When vertical folding is instructed, when the sensor 174 detects paper, the solenoid 114 is energized and the tip of the claw 112 descends toward the lower roller shaft 106 (the state shown by the two-dot chain line in FIG. 4).

In this state, the paper sent directly below the sensor 174 is
The paper is received by rollers 104 and 108, rides on the upper surface of claw 112, and is sent toward vertical folding rollers 116 and 118°120.

Vertical folding rollers 120 and 118 are in contact, but roller 116 does not contact 120 in any state.

The vertical folding roller 116 is supported by a shaft 122 and is rotatable about the shaft. A plunger of a solenoid 124 is connected to the arm to which the roller 116 is pivoted, and when the solenoid 124 is energized, the roller 116 is
is separated from roller 118, and paper that has passed through the upper surface of pawl 112 can enter between rollers 118 and 116. When solenoid 124 is de-energized, roller 116 is
It is in pressure contact with 18.

The fixed register 178 is for positioning the short side of A2 when vertically folding, and the fixed register 154 is for positioning the short side of A2 when vertically folding A2/quarter-folding.
The movable register 126 for long side positioning is B3 during vertical folding.
The positioning of the short side and the movable register 156 are B3
・For positioning the long side of B3 when vertically folding into four.

Plungers of solenoids 130 and 160 are coupled to movable registers 126 and 156, respectively. When solenoid 130 is de-energized, register 12
6 is retracted from the vertical origami paper transport path. solenoid 130
When the register 126 is energized, the register 126 advances into the longitudinal folding paper transport path and stops the incoming paper therein. solenoid 160
When the register 156 is not energized, the register 156 is retracted from the vertical folding paper transport path. When the solenoid 160 is energized, the register 156 advances into the longitudinal fold transport path and stops the incoming paper there.

Rollers 166 and 162 are connected to rollers 104 and 10 when solenoid 124 is energized and roller 116 is pulled up.
8 to feed the paper introduced through the upper surface of the pawl 112 to the register 178 or 126. After the leading edge of the paper is placed against register 178 or 126, solenoid 124 is de-energized and the paper is sandwiched between vertical folding rollers 116 and 118. In this state, the paper is sent toward the register 154 or 156 by these rollers 116 and 118, and when one side of the paper hits the register 154 or 156, the paper bends when it passes between the rollers 116 and 118, and this bending The paper becomes larger and gets caught between the rollers 118-120, folded in half, and sent to the unit 200 through the delivery port (a slit-shaped opening parallel to the axis of the vertical folding rollers) directly below the rollers 118 and 12Q. A steel ball 169 is placed on the roller 166, and a steel ball solenoid 164 is placed opposite the roller 162 so that the rotation of the rollers 166 and 162 does not provide resistance to the movement of the paper during such vertical rotation. ing.

The steel ball 169 is supported by a ball support (not shown) so as to be rotatable in multiple directions, and is constantly in contact with the roller 166.
When 1 and 1 paper arrive, the paper is transferred to roller 1 by its own weight.
66 and rotate as the paper moves. Therefore, when the paper is moving directly under the vertical folding roller 116 in the axial direction of the roller, the rotation of the roller 116 drives the paper in that direction. When the paper moves in a direction perpendicular to the axis of the vertical folding roller 116 (vertical folding in two), the steel balls 169 rotate as the paper moves, so they do not interfere with the paper movement.

The steel ball solenoid 164 has a structure in which an electric coil is wound around a magnetic core, and when the electric coil is energized, the steel ball 165 is attracted to the core and separated from the roller 162. steel ball 1
The steel ball 65 has roughly the same effect on the paper as the steel ball 169, but when driving the paper in a direction perpendicular to the axis of the vertical folding roller 116 (folding in two vertically), the electric coil is energized to The ball 165 is pulled up from the roller 162 (paper) to reduce the frictional resistance of the roller 162.

The folded plate 197 is fixed to a carriage 198, and this carriage 198 is moved in the direction of the arrow (
The roller 116 is guided so as to be able to reciprocate in the axial direction of the roller 116. A link arm 196 is pivotally connected to the carriage 198, and another link arm, which is pivotally connected to the link arm 196, is fixed to the output shaft of the half-rotation clutch 136. A gear fixed to the input shaft of the half-rotation clutch 136 is engaged with a drive power system (not shown) of the unit 100. When the half-rotation clutch 136 is energized, it rotates the link arm 196 half a turn clockwise to drive the carriage 199 (that is, the folded plate 197) to the right, and when the energization is cut off, the half-rotation clutch 136 rotates the link arm 196 in the opposite direction. Turn the carriage 199 (that is, the folded plate 197) by half a turn clockwise.
) to the left.

FIG. 5a shows the folded plate 197 in the standby position.

To the right of the folded plate 197 is a push plate 138. This holding plate 13
8 is fixed to the U-shaped arm 140, and arm 1
40 is pivotally mounted to a carriage 142. The carriage 142 has a guide bar 193 parallel to the guide bar 199.
It is guided so that it can freely move back and forth. An arm 146 is fixed to the carriage 142, and the tip 1 of the arm 146 is fixed to the carriage 142.
95 projects into the path of the carriage 198. A roller 152 is in contact with the U-shaped arc z, ] 40, and this roller 152 is pivotally attached to one end of the rotating arm 148. A plunger 150 of a solenoid 150 is coupled to the other end of the pivot art t, t 48 . In the state shown in FIG. 5a (standby state), the U-shaped arm 140 is held loosely by the roller 152. U-shaped arm 1
40 is spring 145 (left pull) and spring 1
44 (upward pulling), the push plate 138, which is fixed to the U-shaped arm 140 in a doglegged manner, is lifted upward. In this state, the paper fed between the rollers 116-118 passes through the space between the folding plate 197 and the pushing plate 138. When the solenoid 150 is energized, the arm 14
8 rotates counterclockwise, and the roller 152 rotates the arm 140.
Press firmly. As a result, the U-shaped arm 140 rotates counterclockwise, and the entire pressing plate 138 becomes lower than the upper surface of the folding plate 197, pressing the paper downward. When the half-rotation clutch 136 is energized in this state, the folding plate 197 moves to the right and bends the paper as it passes over the push plate 138. When the folded plate 197 moves to the right to some extent, the carriage 1
98 pushes the tip 195 of the arm 146 to the right, which causes the push plate 138 to also move to the right. U-shaped arm 14
0 comes off the roller 152 to the right, the roller 152 prevents the U-shaped arm 140 from returning to the left. When the half-rotation clutch 136 is de-energized in this state, the folded plate 197 returns to the standby position shown in FIG. 5a. When the solenoid 150 is de-energized, the U-shaped arm 140 pushes up the roller 152 by the force of the spring 144, and as a result, the holding plate 138 moves upward and the spring 145
It moves to the left by the force of , and enters the standby state shown in FIG. 5a.

Fig. 5b shows an enlarged plane of the folded plate 197, and Fig. 5c shows its v.
A cross section along the c-vc line is shown, and FIG. 5d shows a cross section along the VD-VD line. The edge of the folding plate 197 on the pushing plate 138 side is shaped like a knife with a sloping lower surface (dotted line), making it easy to fold and hold the paper PR (double-dashed line). Further, the tip of the folded plate 197 has a substantially "C" shape to prevent the paper from escaping. When A2 paper is positioned with the register 178 and when B3 paper is positioned with the register 126, the paper PR (double-dashed line)
As shown in Figure 5b, one corner of the folded plate 1 is triangular in shape.
97, and the paper PR is folded plate 197 and push plate 138
It's between. This state is shown in FIG. 5e.

In this state, when the solenoid 150 is energized, the paper is pressed against a lower paper guide plate (not shown) by the press plate 138. When the half-turn clutch 136 is energized, the folding plate 197 moves to the right as shown in FIG. 5f, folding the corner of the paper over the push plate and the paper above it. Folded plate 197
As the paper progresses further, the push plate 138 also moves to the right, and the push plate 138 comes out of the folded portion of the paper to the right. When the half-rotation clutch 136 is de-energized, the folded plate 197 moves to the left as shown in Fig. 5g, and finally returns to the standby position (Fig. 5e). When the solenoid 150 is de-energized, the push plate 138 returns from the position shown in FIG. 5g to the standby position (FIG. 5e) by the force of the spring 146. At this time, the push plate 138 moves upward due to the action of the spring 144 and does not come into contact with the folded corner piece of the paper PR.

Although not shown, a fixed register 154 used for vertically folding in half for A2/4 folding and a movable register 156 used for vertically folding in 2's for 83/4 folding are parallel to The movable register (154J) and B3

) are installed, and each solenoid (160AJ, 16
0BJ (not shown) to selectively advance into the paper transport path, but since it would complicate the drawing, illustration is omitted in FIG. 5a.

In this vertical folding mechanism unit 100, the roller 108 is connected to the main power system (not shown) of the unit 1-, and rotates when the main power system is in operation.

The rollers 162, 166 and 118 and half-rotation clutch 136 human power system are selectively connected to the main power system through a single clutch. The main power system starts moving in response to a start signal and stops when a predetermined condition is met. For example, it is stopped when an end signal arrives, when a predetermined time has elapsed since the sensor 174 stopped detecting paper, or when a paper jam occurs. The clutch has A2/4-fold mode, A2/JI
It is energized when the S-fold mode, B3/4-fold mode, and B3/JIS fold mode are set.

When a paper jam occurs while the unit 100 is in a state where the solenoid 114 is off), the roller 104 is separated from the roller 108 to remove the jammed paper. When a paper jam occurs in the vertical folding remote L' (solenoid 114 is on) and the jammed paper is caught in the vertical folding rollers 116, 118, and 120, it is difficult to remove it, so the roller shaft 17

Next, details of the operation of the vertical folding mechanism unit 100 will be explained with reference to FIG. 5a.

Operation of the vertical folding mechanism unit lOo (1) A2/4-fold mode--When the sensor 174 detects paper, the solenoids 114 and 124 are energized. When the sensor 176 detects paper, the rotary encoder 297 (
The pulse count shown in Fig. 6a) is started, and the count value is
When the timing value at which the entire leading edge of the paper comes into contact with the fixed register 178 is reached, the solenoid F 24 is de-energized and the solenoid F 164 is energized. When the sensor 176 detects no paper (because a is already caught in the row of the next unit 20'O), the solenoid 164 and ]14 are de-energized.

(2) A2/JIS folding mode--When the sensor 174 detects paper, the solenoids 114, 124 and 160AJ
(not shown) is energized. When the sensor 176 detects paper, the pulse count of the encoder 297 (FIG. 6a) is started, and when the count value reaches the timing value when the entire leading edge of one paper has come into contact with the fixed register 178,
The solenoid 124 is de-energized and the solenoid 164 is energized. When the sensor 176 does not detect paper (because the paper is already caught in the row seams of the next unit 200)
, solenoid 164, 160AJ (not shown) and 114 are de-energized.

(3) B3/4-fold mode---When the sensor 174 detects paper, the solenoids 114, 124, 130 and 16
0 is energized. When the sensor 176 detects paper, the rotary encoder 297 (FIG. 6a) starts pulse counting, and when the count value reaches the timing value at which the entire leading edge of the paper has come into contact with the movable register 126, the solenoid 124 is energized. The solenoid 164 is turned off and the solenoid 164 is energized. When the sensor 176 detects no paper (because the paper is already caught in the second row 1-200), the solenoids 164, 130, 160 and 114 are de-energized.

(4) B3/JIS folding mode--When the sensor 174 detects paper, the solenoid l l 4. 124, 130 and 160BJ (not shown). sensor 17
6 detects paper, the rotary encoder 297 (Fig. 6a) starts counting pulses, and when the count value reaches a timing value at which the entire leading edge of the paper has come into contact with the movable register 126, the energization of the solenoid 124 is cut off. death,
The solenoid 164 is energized. When the sensor 176 detects no paper (because the paper is already caught in the roller of the next unit 2000), the solenoids 164 and 130°16
Cut off the electricity to 0J and 114.

(5) Modes other than the above--All solenoids are de-energized and rollers 104 and 108 are driven.

(6) In addition to this, normal paper jam detection and mechanism stop when a jam is detected.

In FIG. 5h, which shows the structure of the mechanism of another embodiment of the present invention, a lever (
A rotator) 98 is arranged, and one end of the lever 98 is pivotally connected to a fixing pin 97. A pin 99 is fixed to the other end of the lever 98, and this pin 99 abuts the side edge of the arm 195. The end face folding operation by this mechanism is also the fifth
The end folding operation is similar to that shown in Fig. a, but when the carriage 198 moves forward and the cutout moves to the right, the carriage 198 hits the lever 98 and the lever 98 rotates clockwise, causing the arm 195 to move to the right. This causes the push plate 138 to move to the right, but since the carriage 198 pushes the lever 98 between the pins 97 and 99, the push plate 138 moves to the right at a speed faster than the rightward movement speed of the carriage 198. and escapes to the right from below the folded plate 197. in this way,
In this example, when the folded plate 197 moves to the right to some extent,
After that, the pushing plate 138 escapes to the right at a high speed, and the folding plate 1
Evacuate to the right of 97. At the same time that the energization of the half-clutch 136 is cut off, the energization of the solenoid 150 is also cut off, and as the folding plate 197 returns to the left, the push plate 138 rotates upward and returns to the left by the force of the spring 145. In this example,
When the end folding is completed (the folding plate 197 moves to the rightmost side),
The push plate 138 is retracted to the right to a greater extent than the folded plate 197 and the triangularly folded paper, and the push plate 138 rises from a position sufficiently away from the triangular origami and returns to the left.

There is sufficient margin for the retracting operation of the holding plate 138.

7a to 7d show the control operation of the microprocessor 14 of the operation board control unit 10. The control operation of the operation board control unit 10, that is, the control operation of the microprocessor 14 will be explained with reference to these drawings.

Referring first to FIG. 7a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) 14 initializes the input/output ports, registers for temporary data storage, status registers (flags), and counters (program counters).
, timer (program timer), etc. (step 1). In the following, the word "step" will be omitted in parentheses, and only the step symbol will be shown.

After completing the initialization, the CPU 14 reads the status. First, it is checked whether there is a read flag (2
). At this point, initialization has just been completed and there is no read flag, so proceed to step 3 and set standard data in the operation board register. The standard data is: Paper size: A4 Digit selection: Unfolded portrait/horizontal orientation: Landscape Stamp position: Omm Publisher: 1st design (1st publisher's stamp) Drawing type: Temporary drawing (1st drawing type) Punch selection: This is a paper ejection selection without punching option. When this data set is completed, the indicator light corresponding to the data is lit accordingly. In this state, on the operation board 12, wait wi (this is set during initialization).
, A4. No folds, horizontal, Omm, no punch, 1st design,
Indicator lights indicating each of the tray and temporary drawing are lit.

In Figure 6b, 3 assigned to the operating board register OBR
Byte memory area (an area of the internal RAM of the CPU 14)
Indicates the writing position of data to be temporarily written to.

When the standard data is written to the operation board register ○BR, the read flag is set (4). Next, referring to the status of the boat that receives the input signal from the copying machine 800, copy M&8
00, it is determined whether or not a signal is transmitted (5). When there is a transmission, it is received, the signal and data are read, and it is determined whether the signal is a start signal or not (6). If it is not a start signal, it is determined whether it is an end signal or not.7) If it is not an end signal, it is data, so among the input data, data whose memory bit is assigned to the operation board register OBR is stored in the operation board register. Write BR update. When such update writing is performed, 1 is written to the bit indicated as the copying machine input bit of the operation board register ○BR. This l is from the copying machine 800 to the sheet processing machine 900.
This indicates that an instruction was given to Sheet 1 on how to process the sheet. Although not shown, the CPU 14
holds in memory the data received from the copying machine and indicating what has been written to the operation board register ○BR (indicating what the written data is). Copy machine 800
When data is received from the copying machine 80, the writing to the operation bold register OBR is completed, and the process proceeds to step 9.
If there is no input from 0 and the process proceeds from step 5 to step 9, the key input on the operation board 12 is read in this step. If the key-in is from the key switches 12a to 12e (10), refer to the copier input bit, and if it is not 1 (no data has been received from the copier yet), (11)
, updates the contents of the operation register according to the key-in, and turns on the indicator light on the operation board.

Update Off to match this update. For example, when the switch 12a is closed, the size designation bit of the operation board register OBR is set to 1゛A4 at the moment the switch 12a is closed.
The data is updated to indicate the next B3, and the indicator light for A4 is turned off and the indicator light for B3 is turned on. Operation board register OB
When the key switch 12a is closed once when the size designation bit of R is 85, the size designation bit is changed to A2.
, the indicator light B5 is turned off and the indicator light A2 is turned on. In this way, each time the size indication key switch 12a is closed, the lighting of one indicator light moves from the upper side to the lower side in Fig. 6a, and at the same time, the data of the size specification bit of the operation board register ○BR lights up. The data is updated to indicate the size indicated by the indicator light. However, this operation is performed only when the size data has not been received from the copying machine 800; if the size data has already been received, the process proceeds to step 11-12-■ and updates and displays the data in response to the key-in. No updates will be made. key switch 1
The CPU 14 performs similar operations in response to key-ins from 2c to 12h.

The reason why the input data from the copying machine 800 is given priority over the settings made by the operation board 12 is that the input data from the copying machine 800 is prioritized.
This is because data starting from 00 is more reliable. When no data is received from the copying machine (for example, when the copying machine is not connected), or when only part of the required data is received, the missing data is updated and set in accordance with the key input from the operation board 12. When no data is given from the copying machine and there is no key-in on the operation board 12, the setting data becomes the above-mentioned standard data. Although it is different from the step development of the illustrated flowchart, the start signal for the a mechanism of the sheet processing machine to start operation is also received from the copying machine 800, and the start key switch 12i of the operation board 12 is keyed in. However, when even part of the data is being received from the copying machine 800 (copying machine input bit of ○BR = 1), switch 1 is
The key-in of the start signal by closing 2i is step 3.
I try not to add Uke at 8. In this way, even when the processing mechanism is started, priority is given to the star 1 to signal from the copying machine.

The operation board 12 and its key-in reading/data set are meaningful when a copying machine is not connected, and when connected to a copying machine that does not transmit all required data, and when the sheet processing machine 900 is connected to an external device (host ) is not connected, or if the host has insufficient functionality, use key-in to compensate.

Now, if you set the data in step 8 (setting the received data from the copier), or if you set the data in step 13 (setting the key-in data), or the copier will not send data (5)L Maybe there is no key-in (9).

Proceeding to step 14 in FIG. 7b, the signal level of the signal reception port from the unit 20 is referred to to see whether it is ready (paper can be accepted) or not (standby second class cannot be accepted).

If the vertical fold & 90° turn control unit 20 is ready in step 14 of FIG. 7b, the unit 3 is ready in step 16.
Check whether 0 is ready or not. If the vane spar control unit 30 is ready, it is checked in step 18 whether the unit 40 is ready.

If the punch control unit 40 is ready, step 2
0, it is checked whether the unit 50 is ready. If the stamper control unit 50 is ready, it is checked in step 22 whether the unit 1-60 is ready. When the vertical conveyance & paper ejection control unit 60 is ready, all units are ready and can execute sheet processing, so set the ready standby bit of the operation board register OBR to 1 indicating processing is possible24). The data in the board register OBR and the data in the previous operation board register POBR are compared (25). Note that since the pre-operation board register and OBR have been cleared during the initialization in step 1, the contents of the two do not match when the process proceeds to step 25 for the first time. This is for each unit 20 to 6 in steps 27 and below, which will be described later.
Processing mode data transfer to 0 is not being executed.

Therefore, first in step 26, the operation board register OBR is
The data is updated and stored in the pre-operation board register POBR, and the process proceeds to setting the A version processing mode to the unit 20 (27) in FIG. 7c.

To the unit 20 in the A version processing mode in FIG. 7c.
In the setting (27), first, the size is determined from the data of the size designation bit of the operation board register BR (271).

If the size is A2, next refer to the fold selection bit of OBR (272-276). If there is no fold, unit 2
Send data indicating A2/vertical/passing mode to 0 (2
73). When folding into four, data indicating A2/vertical folding mode is transmitted to the unit 20 (27 s). When folding in half, data indicating A2, vertical, and passing mode is transmitted to the unit 20 (277). If it is JIS folding, data indicating A2/end face folding/JIS vertical folding mode is transmitted to the unit 20 (278).

If the size is not A2, the process advances to step 279 to see if it is A3.

If the size is A3, it refers to the length/width designation bit of the OBR, and if it indicates the height (280), it transmits A3/vertical/pass mode to the unit 20 (281).

If it indicates the side, refer to the fold selection bit in OBR 28'2) - If it is unfolded, unit 2
A3/horizontal/passing mode is transmitted to 0 (283). If there is an emergency, the A3 90° turn mode is transmitted to the unit 20.

When the size is A4 (285), refer to the vc/width specification bit (286), and if it indicates the width (
286), and transmits the A4/horizontal/passing mode to the unit 20 (287). Unit 28 unless it indicates the side
Send A4 90° turn mode to 8 (288)
.

When the size is the B version, in step 28, a mode corresponding to the size etc. is transmitted to the unit 20 in the same manner as in step 27 described above. Step 27 A2 to B3, A3 to B
4, and if A4 is read as B5, it becomes the content of step 28.

With the above, when unit 20 is ready, unit 10
A control operation mode instruction is given to the unit 20 from the control unit 20, and is set in the microprocessor of the unit 20.

The CPtJ 14 of the unit 10 then proceeds to set the blade folding mode (29) in FIG. 7d. In this step 29,
First, the fold selection bit of the operation board register ○BR is referred to (291, 292, 294). If there is no fold, size data is attached and the passage is transmitted to the unit 30 (295). In the case of 4-fold, 2-fold, and JIS fold, the data of the size designation bit and the data of the digit selection bit of the operation board register OBR are transmitted to the unit 30 (293, 296). That's all for units 10 to 30.
A control operation mode instruction is given to the unit 30 and set in the microprocessor of the unit 30.

After completing the blade folding mode setting (29), the CPU 14 of the unit 10 sets the punching mode (30).

In this case, refer to the size specification bit data, digit selection bit data, and punch selection bit data of the operation board register OBR (301 to 306, 3
08, 309), when the final size is A4 and punched, send A4/punch mode to unit 40 307), when final size is 85 and punched, send B5/punch mode to unit 40 310
), otherwise the non-punch mode is set to unit 40.
Send to.

After completing the punch mode setting (30), the CPU 14 of the unit 10 sets the stamp mode (3I).

In this case, the stamp selection bit of the operation board register OBR is referred to (312)', and if it is 1 indicating a stamp, the stamp selection bit, stamp position bit, and issuer selection bit of OBR are sent to the unit 50. and send the drawing type selection bit data (313)
. If the unstamped selection bit is 0, it sends an unstamped signal to unit 50.

After completing the stamp mode setting (31), unit 10
The CPU 14 sets the paper discharge mode (32).

In this case, the operation board register OBR is
Please refer to the τ paper selection bit (321), and if it is 1, it will instruct the unit 60 to eject the paper to the sorter (323).
, O, an instruction is given to eject the paper from the tray (322).

After setting the paper ejection mode (32), units 20 to
This means that the control operation mode is instructed to all units 60, and the CPUs of these units each hold the received instructions (mode data).

The CPU 14 of the unit 10 then returns to step 24 in FIG. 7b, and proceeds through step 24 to step 25.

Here, the data of the previous operation board register POBR is changed to the operation board register O by the execution of the previous step 26.
Since it matches the BH data, steps 25 to 3
Proceed to step 3.

In step 33, all the indicator lights on the abnormality display panel 33 are turned off, the standby indicator lamp on the operation board 12 is turned off, and the ready indicator lamp is turned on. Next, a ready signal is output and set to the copying machine 800 (34), and the process returns to step 5 in FIG.
Wait for key-in number 2.

When a start signal arrives from the copying machine 800 (6), refer to the ready/standby bit of the operation board register OBR (35). If it is 1, it is normal operation, so the units 20 to 60 are activated at a predetermined timing. The start signals are sequentially transmitted (37).

The process then proceeds to read the status of the next step. unit 2
When each of 0 to 60 receives a start signal, it starts driving the conveying roller and waits for paper to arrive at each sensor. When paper arrives, predetermined control operations are initiated.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 20 waits (
If the unit 10 is unable to process (processing is not possible) or is on standby, the CPU 14 of the unit 10 reads this in step 14 of FIG. 7b and proceeds to abnormality processing (15) of the unit 20. In this abnormality processing, first, the copying machine input bit of the operation board register OBR is referred to (151). If it is 1, data is received from the copying machine 800, and since the sheet processing has not yet started or has already started, an abnormality (standby) is sent to the copying machine 800 (l52). Then, the ready/standby bit of ○BR is set to O indicating that the operation is disabled, the ready indicator light on the operation board 12 is turned off, and the standby indicator light is turned on (153). Next, the abnormality data is received from the unit 154 (154), and if the abnormal data indicates a paper jam, the abnormality display panel 13 corresponding to the position data is displayed.
Turn on the upper indicator light (156). If the abnormality data indicates that it is not a paper jam, all indicator lights associated with the abnormal mechanism unit on the first display panel 13 are turned on (157). Then, the process returns to the state reading after step 5 in FIG. 7a.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 30 waits (
If the unit 10 is unable to process) or is on standby, the CPU 14 of the unit 10 reads this in step 16 of FIG. 7b and proceeds to abnormality processing (17) of the unit 30. This abnormality processing (17) is similar to the above-mentioned abnormality processing (15).

However, unit 20 in (15) should be read as unit 30.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 40 waits (
If the unit 10 is unable to process (processing is not possible) or is on standby, the CPU 14 of the unit 10 reads this in step 18 of FIG. 7b and proceeds to abnormality processing (19) of the unit 40. This abnormality processing (19) is similar to the above-mentioned abnormality processing (15).

However, unit 20 in (15) should be read as unit 40.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 50 waits (
If the CPU 14 of the unit 10 reads this in step 20 of the 7bth step and proceeds to the abnormality processing (31) of the unit 50, this abnormality processing (21) is the same as the above-mentioned abnormality processing. This is the same as (15).

However, the unit 20 in (15) should be read as the unit 50.

Before or after the control unit IO gives the start signal to the units 20 to 60, the second unit 60 waits (
If the unit 10 is unable to process (processing is not possible) or is on standby, the CPU 14 of the unit 10 reads this in step 22 of FIG. 7b and proceeds to abnormality processing (23) of the unit 60. This abnormality processing (23) is similar to the above-mentioned abnormality processing (15).

However, the unit 20 in (15) should be read as the unit 60.

The operation of the vertical folding mechanism unit 100 brought about by the vertical fold &90'' turn control unit 20 has been explained in the mechanism description section. Therefore, the explanation of the control operation of this unit 20 is omitted here because it is redundant.

30 is mounted on a carriage, and the position of this carriage can be adjusted using screws or the like. Alternatively, the carriage may be driven by a motor to automatically set the position. When assigning several types of folding shapes to one size, a plurality of movable registers may be provided for each size, and one of the movable registers may be selectively driven to the paper stop position.Another register 178 , 156 and 154 may be similarly applied.

Next, the advantages of the embodiments described above will be summarized and explained.

(1) In the vertical folding mechanism unit 100, a conveyance path for paper that does not require vertical folding and a conveyance path for paper that requires vertical folding are separated,
A paper guide gate is arranged between the two, and paper that is not vertically folded is directly sent to the next unit, so the paper feeding speed can be extremely high, and the jam rate is reduced. Switching between a paper conveyance path that does not require longitudinal folding and a paper conveyance path that requires longitudinal folding is simple, and both the mechanism and paper feed control operation are simple.

(2) Paper conveyance path that does not require vertical folding (rollers 104°, 108
) and the vertical folding paper feed path (vertical folding roller 116°↓18,12
0) is in a horizontal-chocho shape, the subsequent seat posture processing is easy, and the vertical folding mechanism unit 100 is made compact.

(3) In the vertical folding mechanism unit 100, by simply adding a movable register, it is possible to select the vertical folding of the A version and the B version. Highly versatile paper size.

(4) End face fold (corner triangular fold) with push plate 138 and fold plate 1
97, and the folded shape is more accurate than when using rollers or the like. Switching between the A version and the B version is performed only by a movable register, and paper feed control is extremely simple compared to the case where rollers or the like are used.

(5) The folded plate has a paper edge in the shape of a "C" on a plane, and a corner of the paper is formed on the straight part of the "C" shape.The raw straight part forms a corner of the paper. Since it is shaped so that one side of the paper is bent by the curved part, it is difficult for the paper to shift as a whole, and it also ensures that the paper is folded in a fixed shape.
